Numerical modeling of turbulent flow in a plane channel on the basis of the Cabaret scheme
Authors: Асфандияров Д.Г.
Published: August 2021

Представлены результаты моделирования классической задачи течения вязкой несжимаемой жидкости в плоском канале по схеме Кабаре при числах Рейнольдса, равных 5600, 13750 и 21900. Расчеты выполнены как при полном (прямое численное моделирование DNS Direct Numerical Simulation), так и неполном разрешении спектра турбулентных пульсаций. Во втором случае для расчетов используются сетки, характерные для моделирования пристенных течений методом крупных вихрей. Для более точного моделирования потока импульса на стенки при грубом разрешении пристенной области вводятся специальные искусcтвенные граничные условия. Это позволяет повысить точность определения средних характеристик течения. Проведено сравнение полученных результатов по схеме Кабаре с результатами прямого численного моделирования по псевдоспектральному методу.

Some results of modeling the classical problem of flow of a viscous incompressible fluid in a plane channel at the Reynolds numbers equal to 5600, 13750, and 21900 using the Cabaret scheme are discussed. The computations are performed for the complete turbulence spectrum resolution (direct numerical simulation) and for the incomplete resolution. In the latter case, the grids typical for the large eddy simulation of nearwall turbulent flows are used. In order to obtain a more accurate representation of the momentum transfer toward the wall, some artificial boundary conditions are introduced. This allows us to model the mean flow characteristics with a higher accuracy. The numerical results obtained by the Cabaret scheme are compared with the numerical results obtained by the pseudospectral method.

On optimization of technical devices based on a hierarchy of mathematical models
Authors: Суровежко А.С. , Мартыненко С.И.
Published: August 2021

Рассмотрена задача о топливном коллекторе, которую можно отнести к обратным задачам гидродинамики: необходимо определить геометрию распределительного канала коллектора, обеспечивающего равномерную раздачу топлива. Однако профилирование коллектора на основе 3D стационарных уравнений Навье-Стокса для турбулентного течения несжимаемой вязкой среды в шероховатых каналах требует непрактичных вычислительных усилий. Использована иерархия математических моделей: 1D уравнения Навье-Стокса для профилирования и 3D уравнения Навье-Стокса для калибровки 1D модели. Показано, что используемая иерархия моделей позволяет существенно снизить объем вычислительной работы, необходимой для расчета оптимальной конструкции коллектора. Предложенный подход представляет интерес для оптимизации технических устройств различного назначения.

A fuel collector problem is considered as an inverse problem of hydrodynamics: it is necessary to determine the distribution channel geometry of a collector for a uniform fuel distribution. However, the collector profiling based on the 3D stationary Navier-Stokes equations for turbulent flow of an incompressible viscous medium in rough channels requires impractical computational efforts. A hierarchy of mathematical models (1D Navier-Stokes equations for the collector profiling and 3D Navier-Stokes equations for 1D model validation) is used in this paper. It is shown that the hierarchy of models can significantly reduce amount of computational work needed for computing the optimal collector design. The developed approach is of interest for optimizing technical devices for various purposes.

Published: August 2021

Системы уравнений с запаздываниями широко применяются в различных областях современного математического моделирования. В ходе разработки структуры математической модели и идентификации ее параметров приходится многократно решать задачу Коши для подобных систем. В случае высокой размерности системы, а также при условии жесткости задачи численное решение уравнений с запаздываниями может требовать значительных вычислительных и временных затрат. Таким образом, разработка и реализация эффективных алгоритмов численного решения различных классов уравнений с запаздывающими аргументами является актуальной задачей. В настоящей статье представлена модифицированная версия программного комплекса DIFSUBDEL, в которой реализованы методы численного решения дифференциальных уравнений с запаздываниями на основе линейных многошаговых методов. Переработанная версия разработана с применением принципов структурного программирования и является значительно более удобной в эксплуатации, чем исходная, а также обладает свойством потокобезопасности, что позволяет использовать комплекс в качестве блока в системах, основанных на технологиях параллельного программирования с общей памятью. Был проведен сравнительный анализ производительности переработанной системы DIFSUBDEL c другими существующими программными реализациями численных методов решения дифференциальных уравнений с запаздыванием и показана ее эффективность.

The systems of delay differential equation are widely used in modern mathematical modeling. The process of mathematical model development and identification requires the repeated solution of initial value problems for such systems. The numerical solution of delay differential equations may be computationally expensive, especially when the problem is stiff and high-dimensional. Therefore, it is important to develop and implement the efficient algorithms for the numerical solution of different classes of delay differential equations. In this paper, a new implementation of DIFSUBDEL program package for the numerical solution of delay differential equations based on linear multistep methods is discussed. The modified version is based on structured programming principles to make the program thread safe and user-friendly. The modified program performance is compared with the existing implementations of numerical methods for the solution of delay differential equations.

Authors: Grebenyuk A. A. , Subbotin A. A.
Published: August 2021

The article сarries out an analysis of the practices of using electronic social networks (Facebook, Twitter, Vkontakte, etc.) in the study of migration processes. The paper shows how alternative to traditional sources (administrative, surveys) data allow us to form an up-to-date idea of the spatial-temporal and socio-demographic characteristics of migration. The authors study the integration of migrants in destination countries, including difficulties of assimilation and identity preservation, geography of migration flows, migration due to natural disasters and political reasons, intellectual and labour migration. The specificity of the data generated by social networks is that they cover the entire population and are produced in real time.

The paper highlights the search for the necessary information using the means of platforms – advertising plugins, geolocation in posts and information directly collected from users, the functioning of certain communities, published comments. 

The study also gives important methodological features, the success of the results of any research conducted through the analysis of electronic social networks depends on the consideration of which. The problem of the information obtained with their help lies in such limitations as accessibility (technical features of specific platforms), representativeness (insufficient development of statistical techniques for evaluation) and variability of user preferences. In conclusion, the authors conclude about the prospects of using digital mass communication media in the study of migration processes.

The scientific and practical significance of the research paper lies in the fact that it complements the literature on the topic under consideration, being the first systematic review of it in the Russian language, and also provides recommendations on the use of the information obtained.

Narrativas, infância e educação: reflexões e perspectivas
Authors: Pulino: Lúcia Helena Cavasin Zabotto
Published: August 2021

Este artigo, inspirado em texto poético-filosófico de Walter Benjamin, propõe-se a tratar criticamente as narrativas sobre educação e crianças, num sentido amplo, envolvendo formas de relações em contextos educativos, expressas por palavras, práticas e afetos. Por meio de reflexões filosóficas relacionadas Ã  perspectivas teóricas e metodológicas nos campos do desenvolvimento humano e da educação, problematiza-se a formação de educadores da infância. Criticam-se propostas de formação por se sustentarem em narrativas prescritivas de como deve ser o humano que não abrangem a sua complexidade e a singularidade das pessoas, nem tampouco aceitam a diferença como possibilidade do humano e não como desvio da normalidade. A partir dessa crítica, busca-se traçar uma proposta teórico-metodológica que possa superar as contradições apontadas e que se defina a partir de uma narrativa aberta a novas possibilidades de relações, ao conflito, ao desacordo, Ã  diversidade da experiência humana. Que seja, enfim, uma metodologia de pesquisa e intervenção que possa dar espaço para uma narrativa gestada em “lugares de infância”, marcada pela pergunta, pelo não saber, pelo encontro com o outro, especialmente com a infância.
sociedade de risco e a noção de cidadania: desafios para a educação científica e tecnológica
Authors: Pietrocola Maurício , Souza Carolina Rodrigues de
Published: August 2021

Ulrich Beck, em uma obra de 1986 intitulada "sociedade de risco", afirma que a vida social moderna se defronta com novas formas de perigo produzidas por ela mesma e que desafiam a humanidade. Isso implica que viver em uma "sociedade de risco" seria assumir uma atitude calculista em relação às possibilidades de ação, positivas e negativas, com que somos continuamente confrontados. Esse confronto impacta tanto a existência em nível individual, quanto em nível global. Neste trabalho pretende-se abordar de que forma essa avaliação da modernidade social impacta a noção de cidadania e coloca em suspensão as perspectivas contidas nas abordagens CTS e Alfabetização Científica e avança-se a discussão sobre os desafios da educação científica moderna reflexiva.

Authors: Lira Aliandra Cristina Mesomo , Machado Leandra Souza
Published: August 2021

O artigo tem como objetivo problematizar a obrigatoriedade de matrícula na pré-escola para crianças de 4 e 5 anos de idade, proposta pela Lei 12.796, e compreender qual a percepção dos pais com relação aos encaminhamentos envoltos no cumprimento da lei. A pesquisa é de cunho qualitativo, partindo de referencial teórico e análise documental, e entrevistas com os responsáveis pelas crianças matriculadas na pré-escola. Foi possível reconhecer que a obrigatoriedade não necessariamente significa uma pré-escola de qualidade, e que os responsáveis interpretam a implementação da lei como direito ‘de aprender’ mais cedo, a despeito das condições de atendimento.

Authors: Ainy Asmaripa , Misnaniarti  , Fatmalina Febry  , Dian Safriantini
Published: August 2021

Local-food-based complementary feeding (LFBCF) practice may be an important approach in the growth and development of children aged 6 to 24 months. This study aimed to describe potential barriers in implementing local food-based complementary feeding practices among mothers in Banyuasin regency, Indonesia. A qualitative study was conducted by using 24 semi-structured interviews and a focus group discussion. Participants were 24 mothers with children aged 6 to 24 months in Banyuasin Regency, Indonesia that recruited purposively. Data were analyzed using thematic analysis. The majority of the mothers were 20-30 years old. All participants have implemented LFBCF practice because local food ingredients are easy to find locally at an affordable price. Community cadres assisted village midwives in integrated health post service such as disseminating information concerning local food recipes and facilitating information exchange among mothers regarding complementary feeding practice. Three main emerged themes identified from this study were: mother's knowledge about local food recipes, mother's knowledge about healthy complementary food preparation, child-eating behavior. Improving the nutritional status of children starts with the family by motivating mothers to provide complementary foods, which also requires the support of local cadres.

Authors: BOZDUMAN Seda , GÜLER AKSU Gülen , TOROS Fevziye
Published: August 2021

Amaç: Majör depresif bozukluk (MDB) veya anksiyete bozukluğu (AB) tanılı ebeveynlerin çocuklarında yıkıcı duygudurum düzenleyememe bozukluğu (YDDB) başta olmak üzere ruhsal bozuklukların araştırılması amaçlanmıştır. Yöntem: Mersin Üniversitesi Tıp Fakültesi Psikiyatri polikliniğine Eylül 2018-Eylül 2019 tarihleri arasında başvuran MDB olan 46 ve AB olan 34 ebeveynin 6-18 yaşları arasındaki 80 çocuğu çalışmaya dâhil edilmiştir. Kontrol grubunu, herhangi bir psikiyatrik rahatsızlığı olmayan Mersin Üniversitesi Tıp Fakültesi pediatri polikliniğine basit fiziksel yakınmalar ile başvuran sağlıklı ebeveynlerin aynı yaştaki 40 sağlıklı çocuğu oluşturmaktadır. Çocuk ve ebeveyn ile Okul Çağı (6-18 Yaş) Çocukları İçin Duygulanım Bozuklukları ve Şizofreni Görüşme Çizelgesi-Şimdi ve Yaşam Boyu Versiyonu Türkçe (ÇGDŞ-ŞY-T), Beck depresyon, Beck anksiyete, DSM-IV’e dayalı DEHB tanı ve değerlendirme ölçeği, Çocukluk Çağı Kaygı Bozuklukları Ölçeği (ÇATÖ), Çocuklar için Depresyon Ölçeği (ÇDÖ) uygulanmıştır. Bulgular: Çalışmamızda ebeveyninde AB ve MDB olan çocuklarda daha fazla ruhsal bozukluk saptandı. En sık görülen psikopatoloji DEHB iken bunu YAB, MDB, sosyal fobinin takip ettiği görüldü. Tüm örneklemde DSM-5’e göre sadece bir olgu (%2.9) YDDB tanısını karşıladı. Hem MDB hem AB grubunda karşıt olma karşı gelme puanları (p=0.019), AB grubunda ise davranım bozukluğu puanları (p=0.043) kontrollerden anlamlı düzeyde yüksekti. Sonuç: Ebeveynlerinde ruhsal bozukluk olan çocuklar psikopatoloji gelişimi açısından risk altındadır ve ebeveynlere yönelik uygun tarama programlarının geliştirilmesi önem arz etmektedir. Çocuk psikiyatri kliniklerine en sık başvuru şikâyetleri sinirlilik, öfke patlamaları gibi YDDB semptomları iken çalışma sonuçları tanısal anlamda YDDB’nin düşük olduğunu göstermiştir. Bu durum ileri çalışmalarda daha çok YDDB’nin semptomlar düzeyinde irdelenmesinin faydalı olabileceğini düşündürmektedir.
Storage stability of yoghurts enriched with coriander (Coriandrum sativum l.)
seeds extract
Authors: Jameel Q.Y. , Mohammed N.K.
Published: August 2021

This study was aimed to estimate the effects of the extract of coriander seed during
storage on the chemical and sensory properties of yoghurt. Coriander seed extract was
incorporated into yoghurt at different concentrations, 18 mg/mL (T1C1), 36 mg/mL
(T2C2) and 54 mg/mL (T3C3) respectively, while control was performed using a sample
without extract (T0C0). Samples were stored at 4°C for 42 days and every seven days
were evaluated. For all samples containing extract, the values of lactose, fat, pH, protein,
tyrosine, acid degree value, acid value, free fatty acid and sensory properties gave higher
scores than those of yoghurt without extract. A major deterioration beyond 28 days of
storage due to high acidity and an unpleasant taste was discovered by chemical and
sensory evaluations of the yoghurt without plant extract. On the other hand, concentrations
of 18, 36 and 54 mg/mL had shown to have a remarkable 42-day preservation activity in
yoghurt. Compared to formulas T1C1 and T2C2, which contained 18 mg/mL and 36 mg/
mL respectively, formula T3C3, fortified with coriander seed extract at 54 mg/mL, had the
highest value in maintaining the chemical properties of yoghurt after 42 days. The
findings indicated that coriander extract can be applied as a natural food preservative to
milk products in order to increase stability during storage.
The impacts of camera placement on species detectability in an Indonesian terrestrial community
Authors: Van Dam Eric
Published: August 2021

Ecologists have increasingly favoured the use of camera traps in studies of animal populations and their behaviour. Because camera trap study design commonly implements non-random selective placement, we must consider how this placement strategy affects the integrity of our data collection. Selective placement of camera traps have the benefits of 1) maximizing the probability of encounter events by sampling habitats or microhabitats of known significance to a focus or closely-related species and 2) reducing data collection and maintenance effort in the field by situating cameras along more easily-accessible landscape features. Introducing a non-random survey method, such as selective placement, into a project studying a species or community that also expresses non-random habitat use may lead to unintentionally biased data and inaccurate results. By using a paired on-trail/off-trail camera-trap study design, my aim is to investigate potential differences in popular ecological indices, species detection probability (p) using multi-method occupancy models, and intraspecific temporal activity for a terrestrial community in Gunung Palung National Park in Indonesian Borneo. Differences in detection probability between on and off-trail cameras were compared against species characteristics (including body size, diet, and taxonomic group) to find potential correlations. While several species exhibited a significant difference in detection probability between cameras placed on foot trails and those placed randomly off-trail, there was no measured community trend. This stresses my conclusion further that a non-random study design leaves results open to bias from unknown patterns in detection due to underlying variation in behaviour and microhabitat use. Selective placement may be effective for increasing detection probability for some species but can also lead to substantial bias if the features selected for are not explicitly taken into account within the analysis or balanced with a control in the study design. In addition, a positive interactive effect was found between on trail species detection and body size for the terrestrial omnivore guild, and three species presented significant variation in temporal activity between camera placement types. This provides evidence that camera placement not only affects species state parameters and indices but has a noticeable impact on behavioural observations that require accountability as well.
Gravity constraints on structure of the East-West Antarctic lithospheric transition zone
Authors: Treweek Sam
Published: August 2021

The differing structural evolution of cratonic East Antarctica and younger West Antarctica has resulted in contrasting lithospheric and asthenospheric mantle viscosities between the two regions. Combined with poor constraints on the upper mantle viscosity structure of the continent, estimates of surface uplift in Antarctica predicted from models of glacial isostatic adjustment (GIA) and observed by Global Satellite Navigation System (GNSS) contain large misfits. This thesis presents a gravity study ofthe lithospheric transition zone beneath the Taylor Valley, Antarctica, conducted to constrain the variation in lithological parameters such as viscosity and density of the upper mantle across this region.

During this study 119 new gravity observations were collected in the ice-free regions of the Taylor Valley and amalgamated with 154 existing land-based gravity observations, analysed alongside aerogravity measurements of southern Victoria Land. Gravity data are used to construct 2D gravity models of the subsurface beneath this region. An eastward gradient in Bouguer anomalies of ~- 1.6 mGal/km is observed within the Taylor Valley. Models reveal thickening of the Moho from 23±5 km beneath the Ross Sea to 35±5 km in the Polar Plateau (dipping at 24.5±7.2°), and lithospheric mantle 100 km thicker in East Antarctica (~200±30 km) than West Antarctica (~90±30 km).

Models of predicted surface uplift history are used to estimate an asthenospheric mantle viscosity of 2.1x1020 Pa.s at full surface recovery beneath the Ross Embayment, differing by ~14% from the viscosity at 50% recovery. The temperature contrast between lithospheric and asthenospheric mantle is estimated as ~400°C, equivalent to a viscosity that decreases by a factor of about 30 over the mantle boundary.

Results demonstrate that the history of surface uplift in the study area may be complicated, resulting in observations of uplift, or subsidence, at GNSS stations. Future work should incorporate additional geophysical methods, such as seismicity and electrical resistivity, improving constraints on gravity models. A better understanding of the surface uplift (or subsidence) history in the Transantarctic Mountains is critical, with implications in reducing uncertainty in GIA models.

Authors: Wang Hui , Tang Ting , Jin Min , Fang Lili , Ou Aihua
Published: August 2021

Objective: To analyze and evaluate the clinical efficacy of different treatment options for patients with peri-implant infection. Methods: The study period was from June 2019 to June 2020. Seventy-six patients with peri-implant infection that were treated in Stomatological Hospital of Hefei were selected as study samples. The patients were divided into a research group and a control group by random number table method in which the sample size of each group was n=38. Patients in the control group were treated with drugs combined with ultrasonic cleaning while patients in the research group were treated with guided bone regeneration combined with flap curettage. The indicators of the two groups were compared and analyzed. Results: The plaque index (PLI), probing depth (PD), and sulcus bleeding index (SBI) of the two groups after treatment were lower than those before treatment (P < 0.05). There was no significant difference between the groups (P > 0.05). However, the height of the implant marginal bone of the study group after treatment was higher than that of the control group (P < 0.05). Conclusion: The use of guided bone regeneration combined with flap curettage for patients with infection around dental implants promotes the fusion of bone and implants. The clinical effect was significant and this should be comprehensively promoted in medical institutions at all levels.

Objective: To discuss the management of safe medication in the treatment of internal diseases in traditional Chinese medicine. Methods: 124 patients with medical diseases were divided into experimental group and control group by random number table method, with 62 cases in each group. The experimental group implemented safe medication management, and the control group implemented routine medication management, all of which were treated for 4 consecutive weeks. The comparison of the improvement of the quality of life, the compliance rate of safe medication and the adverse drug reactions of the two groups after clinical treatment were compared. Results: After 8 weeks of treatment, there was a significant difference in clinical efficacy between the two groups of patients. In terms of quality-of-life scores, the scores of the experimental group were better than those of the control group. The living ability, condition, physical strength and other conditions of patients were significantly different. The t-values were 15.3427, 14.0275, and 7.7113, respectively, and P<0.01 was statistically significant. The compliance rates of patients in the experimental group and observation group were 95.16% and 70.96%, respectively, with significant differences (P<0.05). In terms of the incidence of adverse drug events, the experimental group was 3.22%, which was significantly lower than the observation group’s 8.06% (P<0.05). Conclusion: The implementation of safe medication management in the clinical treatment of TCM internal diseases can improve the quality of life of patients to a certain extent, increase their safe medication compliance rate, and reduce the incidence of adverse medication events. The clinical application value is extremely high, and it can be widely promoted and applied.

Authors: Zhao Kai
Published: August 2021

Objective: To observe the significance of EZH2 and BMI-1 protein expression in the carcinogenesis process of colon serrated adenoma (SSA/P). Methods: Hematoxylin-eosin (HE) staining was used to observe the morphological characteristics of normal tissues, hyperplastic polyp (HP), SSA/P and colon cancer. Immunohistochemical staining was used to detect the expression of EZH2 and BMI-1 protein. The relative expression of EZH2 and BMI-1 was detected by qRT-PCR. Results: Compared with normal tissues, HP and colon cancer tissues, SSA/P showed serrated glandular hyperplasia, glandular dilatation, and deep nuclear staining, which had certain atypia. The positive expression rates of EZH2 and BMI-1 protein were 53.3% and 56%, which were close to those of colon cancer (66.7% and 76.6%) and higher than those of normal group and HP (16% and 8%, P < 0.05). The relative expression of EZH2 and BMI-1 in SSA/P tissue was significantly higher than that in normal group and HP, but lower than that in carcinogenesis group (P<0.05). Conclusion: EZH2 and BMI-1 play an important role in the carcinogenesis of colon serrated adenoma, and can be used as the primary screening index before carcinogenesis.

Authors: Li Xiaoyu , Feng Sina , Zhang Hui
Published: August 2021

Constipation is one of the common gastrointestinal complications of stroke, which not only affects the quality of life of patients, but also easily induces and aggravates the primary disease and delays the recovery of the disease. At present, most of the treatments for constipation after stroke are oral medicine and enema, but the curative effect is poor and unstable. Acupuncture has the advantages of simple operation, remarkable effect, high patient acceptance and a little toxic effect. It is one of the non-drug treatment ways to prevent and treat constipation after stroke, as well as widely used in the treatment of constipation after stroke. Therefore, the clinical research on acupuncture treatment of constipation after stroke in recent years is summarized to provide reference for the subsequent clinical treatment of constipation after stroke.

The primary outcome was defined as the need for mortality or liver transplantation. Adverse effects and liver biochemical variables were a secondary outcome. Results: Nine randomized controlled trials, involving six different treatment regimens with a total of 996 patients, were included in the analysis. On meta-analysis, IAs was not associated with a reduction in risk of mortality or liver transplantation (risk ratio [RR]: 0.92, 95% confidence interval [CI]: 0.69-1.22, P = 0.57, I2 = 0%), and have resulted in more adverse effects (RR: 1.44, 95% CI: 1.08-1.92, P = 0.01, I2 = 19%). Subgroup analysis showed that IAs monotherapy caused adverse effects such as diarrhea, abdominal pain, and renal insufficiency (RR: 1.36, 95% CI: 1.01-1.82, P = 0.04, I2 = 48%). IAs therapy did not prominently improve markers of liver function except for alkaline phosphatases (weighted mean difference [WMD]: -0.38, 95% CI: -0.62 to -0.14, P = 0.002). Conclusions: IAs cannot reduce the risk of mortality or liver transplantation, whether in IAs monotherapy or combination therapy, and even be associated with more adverse effects.

Authors: Yang Yanjing , Zhu Hongli
Published: August 2021

Objective: To systematically evaluate the efficacy and safety of didroxyprogesterone combined with progesterone in the treatment of luteal insufficiency abortion. Methods: We searched CNKI database, VIP database, Wanfang database, PubMed database, EMBASE database and Cochrane library database for literatures on the treatment of luteal insufficiency-induced abortion with didroxyprogesterone and progesterone. Meta-analysis was performed using Revman 5.3 software after literature extraction and further quality evaluation. Results: Ten randomized controlled trial-related articles that describe studies on a total of 1145 patients, 570 in the combination group and 575 in the control group, were included. The results of meta-analysis showed that combination therapy could improve the effective rate of fetal protection (OR = 0.14, 95% CI [0.07, 0.27], P < 0.00001). The safety of the combination group was significantly higher than that of the control group (OR = 3.09, 95% CI [1.13,8.48], P = 0.03). Conclusion: To sum up, compared with the control group, the combination of progesterone and progesterone is more effective and safer in the treatment of luteal insufficiency abortion. However, the sample size of the data is relatively small and the quality of the literature is low. This conclusion still needs to be further verified in high-quality randomized controlled trials that involve large samples.

The main cause of infertility in elderly women is poor ovarian function, decreased quality and number of oocytes, which ultimately leads to poor fertility. Low ovarian function is the most difficult point in the research of reproductive medicine and reproductive health. At present, the treatment of integrated traditional Chinese and Western medicine has gradually achieved results. Western medicine mainly regulates endocrine and assisted reproductive treatment by supplementing estrogen and progesterone, while traditional Chinese medicine (TCM) mainly focuses on invigorating the kidney, adding and subtracting according to the syndrome. The treatment effect of TCM or western medicine alone is not significant. Many clinical observations show that integrated TCM and western medicine focuses on the specialties of western medicine, which not only makes up for the insufficiency of the slow action of TCM, but also improves its clinical efficacy when combined with western medicine. Based on domestic and foreign research, this article summarizes the treatment of infertility in elderly women with integrated TCM and western medicine.
