Air Pollutants and Viral Transmission
Authors: Chen Baicheng
Published: July 2021

Viral infection, especially respiratory viral infection (RVI), is currently one of the infectious diseases with the highest mortality, and the hospital admissions of viral infection rises every year particularly in the developing countries. Researchers currently suspect that there is a certain correlation between levels of air pollution and the ease of viral transmission. In most cases, the hospital admissions of airborne diseases show a positive correlation with the level of air pollutant in that area. Several reasonable explanations for this association have been given based on observations, but none of these theories has yet been well justified, and more researches have to be done. The aim of this article is to discuss the correlation between level of air pollution and the ease of viral transmission, the possible causes of this association, including the physical traits of air pollutant trapping viruses, and the reduced amount of virus-killing rays in sunlight due to air pollution, to offer possible solutions to lower incidence rate of viral infections, and to attract more attentions on exploring this correlation.

Authors: Li Huan , Zhang Xiaofeng , Li Zhe
Published: July 2021

With the popularization of clinical ultrasound technology, small follicular ovulation infertility is gradually being recognized in clinical practice. Low follicle ovulation refers to the phenomenon that the average value of the three diameter lines of the dominant follicle is less than 14mm-18mm under continuous ultrasound monitoring. The dominant follicle ovulates before it develops to maturity, which is a kind of ovulation disorder and one of the leading causes of unexplained infertility, accounting for 25%-30% of the total number of patients with infertility. At present, Western medicine mostly uses ovulation, stimulating drugs to treat this disease. Still, due to the clinical result of "high ovulation but low pregnancy", there are certain obstacles in treatment. The purpose of this article is to discuss Zhang Xiaofeng's understanding of TCM of this disease. The tutor believes that the location of the disease is in the kidney, and the mechanism of the disease is kidney yin deficiency and blood heat. The treatment principle is sequential therapy, nourishing yin and clearing heat, taking into account the protection of the spleen and stomach, and the therapeutic effect is perfect.

Published: July 2021

This study aimed to investigate the sleep quality of medical staff in China who are combatting novel coronavirus pneumonia (COVID-19). To perform this, a survey of 127 medical staff from three separate wards (the general ward, isolation ward, and fever clinic) of a Grade A tertiary hospital in China was conducted. The survey questionnaire measured general characteristics and included the Pittsburgh Sleep Quality Index (PSQI). We consequently found that global PSQI scores differed significantly between the different wards (?2 = 44.561, P<0.001). Whilst the medical staff in the general ward did not report any sleep disturbances, those in the isolation ward and the fever clinic both exhibited various degrees of sleep disturbance (global PSQI score > 7). Medical staff in the isolation ward had the worst sleep quality (mean rank = 91.74), followed by those in the fever clinic (mean rank = 70.52) and the general ward (mean rank = 39.10), respectively. The primary sleep disturbances reported by the medical staff from the isolation ward included difficulty falling asleep (24 cases, 71.42%), waking early or at night (28 cases, 80%), and nightmares (18 cases, 51.42%). In addition, 31.42% (11 cases) of the medical staff from the isolation ward had less than six hours of sleep a night, and 65.71% (23 cases) felt that their sleep quality was poor; meanwhile, for the staff from the fever clinic these ratios were 16.67% (seven cases) and 33.33% (14 cases), respectively. In contrast, among medical staff in the general ward, 98% (49 cases) reported sleeping for more than six hours a night, and 96% felt that their sleep quality was good. In conclusion, of the medical staff providing treatment for COVID-19, those in isolation wards and fever clinics are more likely to experience sleep disturbances.

Published: July 2021

Bladder tumor is characterized by recurrent recurrence and distant metastasis, which determines the difficulty of completely curing bladder tumor. In recent years, the number of patients with bladder cancer is increasing, and the treatment of bladder cancer has become an important direction of clinical research. It is difficult to control bladder tumor by traditional therapy. Photodynamic therapy (PDT), as a new optical therapy, has gradually become the main method in clinical treatment of bladder tumor combined with transurethral resection of bladder tumor. In this paper, a patient with superficial recurrent bladder tumor was treated by photodynamic therapy combined with transurethral resection of bladder tumor. The advantages of photodynamic therapy in the treatment of bladder tumor and the selection of photosensitizer in the process of photodynamic therapy were discussed. After two recurrences, the patients chose photodynamic therapy. The tumors were resected one by one, and the wound was coagulated by roller electrode. After the drug was retained for 20 minutes, the bladder was empty. The spherical optical fiber was implanted into the bladder. The photodynamic energy was adjusted (light power 1.8 W, light time 1302 s). There was no recurrence after operation.Most bladder tumors are superficial tumors, and bladder is a cavity organ, which determines that bladder is an ideal organ for photodynamic therapy. As a targeted drug, photosensitizer is only absorbed by bladder tumor after being perfused into bladder. The photosensitizer forms reactive oxygen species through oxygen and kills tumor cells. Clinical practice has proved that PDT has its unique advantages for superficial and recurrent bladder tumors. As the first generation photosensitizer, xipofen also has selectivity in the treatment of bladder cancer.

However, after treatment, the levels of cytokeratin 19 soluble fragments (CYFRA21-1), carbohydrate antigen 125 (CA125), and carcinoembryonic antigen (CEA) in the study group were lower than those in the control group (P < 0.05). The effective rate and the quality of life score of the study group were higher than those of the reference group while the incidence of adverse reactions was lower than that of the reference group, P < 0.05. Conclusion: Lung-fire-clearing, phlegm-resolving, and bowels-relaxing decoction can effectively improve the symptoms of patients with lung cancer and improve their quality of life.

The residual amounts of glyphosate in wheat grain after desiccation of crops were determined. Glyphosate is the most widely used herbicide in the world. The level of its ecotoxicity is widely discussed in the scientific literature after the compound was classified as “a likely carcinogenic” pesticide. It is assumed that glyphosate residues can be highest when the crops are desiccated before harvesting. The studies were carried out in 2018 (central forest-steppe of the Novosibirsk Ob region (54°53'13.5"N, 82°59'36.7"E). In the experiment, desiccation of wheat was carried out with the herbicide Zero Super (the content of isopropylamine salt of glyphosate was 750 g/kg) at the recommended dose of 1.5- 2.0 kg/ha. Glyphosate residues in plant biomass were determined using the test system, based on the principle of enzyme immunoassay. Pre-preparation of the samples for the analysis was carried out according to the recommendation of Stylab laboratory, which validated the method for the determination of glyphosate in grain. Glyphosate residues were found in all of the 37 samples tested. Regardless of the sampling period after desiccation, herbicide residues in the grain did not exceed 4.4 mg/kg. In 14 days after desiccation, the minimum pesticide level was lower (0.5 mg/kg) compared to the data obtained in 7 days (2.6 mg/kg). The content of the herbicide residues in wheat straw was higher than in grain. The highest values of glyphosate residues were found in the dry biomass of weed vegetation (up to 9 mg/kg). In the grain stored for 1 year, the content of GR has not decreased. The data obtained were compared with the MRL for the residual amount of glyphosate in wheat grain accepted in the world.

En la parte alta del municipio de Huasca de Ocampo, Hidalgo, el suelo (regolito) es producto de la intemperización de materiales volcánicos con altas tasas de infiltración de agua (13.25 mm día-1) con serias dificultades para almacenar agua. El objetivo de la investigación fue evaluar, en términos de su permeabilidad y costo económico, técnicas de sellado para reducir la infiltración en el área de embalse de un proyecto de bordo de almacenamiento localizado en un suelo residual volcánico. Se evaluaron variables físicas, químicas y mecánicas del suelo. Se aplicaron 46 tratamientos con sus respectivas repeticiones, para sellar el suelo. Se midió en permeámetro de carga constante el coeficiente de permeabilidad del suelo en dos etapas para comparar el efecto a través del tiempo. Los datos de permeabilidad se sometieron a un análisis de varianza (ANDEVA) y la comparación de medias se hizo con el método de la diferencia mínima significativa (LSD), para un nivel de significancia α = 0.05. Con resultados de permeabilidad se elaboró un análisis económico, comparando los precios unitarios de los tratamientos contra el precio de la geomembrana. En términos económicos y en control de la infiltración los tratamientos con dispersantes de partículas (carbonato de sodio, tripolifosfato de sodio y fosfato de sodio) son recomendables, aunque hay que considerar aplicaciones de mantenimiento cada dos o tres años. El tratamiento más económico fue la compactación próctor estándar, sin embargo, esta alternativa no es recomendable por presentar el suelo incrementos de permeabilidad con el tiempo. El uso del cemento-arena y la bentonita sódica resultaron muy eficaces, aunque sus costos son elevados, tienen la ventaja de ser una alternativa duradera.

The objective of biofortification is the human consumption of high nutritional quality food, rich in micronutrients. Selenium (Se) is an essential micronutrient in human nutrition, and its essentiality has not been evidenced in plants. However, its application in crops and subsequent consumption can mitigate the deficiency of this micronutrient in the diet of human populations. This work analyzes the capacity of sodium selenite (Na2SeO3) to increase yield, biosynthesis of bioactive compounds and their accumulation in tomato fruits. For this, five treatments were applied via nutrient solution: 0, 2, 4, 6, and 8 mg L-1. At harvest, the nutraceutical quality and the accumulation of Se in fruits were quantified, as well as the productivity of tomato plant. Biofortification was positively affected by the biosynthesis of phytochemical compounds and their concentration in fruit, although tomato yield decreased. The incorporation of Se in nutritive solution is an alternative to increase both the biosynthesis of phytochemical compounds and the concentration of this element in tomato fruits with the possibility of improving public health through its consumption.
