Abstract
Coronary artery disease (CAD) is a life-threatening medical emergency which needs urgent medical attention. Percutaneous coronary intervention (PCI) is common and necessary for patients with CAD. The effect of hypercholesterolemia and diabetes on long-term outcomes in patients with stable CAD receiving PCI is unclear.
In this study, patients with stable CAD who underwent PCI were prospectively divided into 4 groups according to the presence or absence of diabetes or hypercholesterolemia. Clinical characteristics, risk factors, medications, angiographic findings, and outcome predictors were analyzed and long-term outcomes compared between groups.
Of the 1676 patients studied, those with hypercholesterolemia and diabetes had the highest all-cause mortality rate after PCI (P < .01); those with diabetes only had the highest cardiovascular (CV) mortality (P < .01). However, the 4 groups did not differ in rates of myocardial infarction (MI) or repeated PCI. In Kaplan–Meier survival analysis, patients with diabetes only had the highest rates of all-cause mortality and CV mortality (both P < .001). In the Cox proportional hazard model, patients with both hypercholesterolemia and diabetes had the highest risk of all-cause mortality (hazard ratio: 1.70), but groups did not differ in rates of MI, CV mortality, and repeated PCI.
With or without hypercholesterolemia, diabetes adversely impacts long-term outcomes in patients receiving PCI. Diabetes mellitus seemed to be a more hazardous outcome predictor than hypercholesterolemia. Hypercholesterolemia and diabetes seemed to have an additive effect on all-cause mortality in patients after receiving PCI.

Abstract
We aimed to investigate heart rate recovery (HRR) in patients with transient ischemic attack (TIA) and the relationship between HRR and health-related quality of life (HRQOL).
All available patients were enrolled during the enrollment period. A total of 120 patients with TIA and 120 healthy controls were included in this study. A treadmill stress test was performed to calculate the HRR. The HRR were calculated as follows: HRR 1, 2, 3, and 5 minutes = heart rate at peak during exercise − heart rate at 1, 2, 3, and 5 minutes at rest. All patients enrolled were asked to fill in the Short Form 36 Health Survey to calculate HRQOL.
We found that the maximum heart rate of TIA patients was significantly higher than that of healthy controls (166 ± 11 vs. 162 ± 14 beats/min, P = .015). Similarly, maximum systolic blood pressure (SBP) and diastolic blood pressure (DBP) were higher in TIA group compared with healthy control group (SBP: 172 ± 15 vs. 165 ± 14 mm Hg, P < .001; DBP: 102 ± 12 vs. 93 ± 16 mm Hg, P < .001). The HRR were significantly lower in TIA group compared with control group (TIA vs. controls, HRR1: 17 ± 7 vs. 30 ± 8 beats/min, HRR2: 32 ± 11 vs. 49 ± 9 beats/min, HRR3: 43 ± 13 vs. 63 ± 12 beats/min, HRR5: 54 ± 16 vs. 73 ± 15 beats/min, all P < .001). Multivariate analysis showed that older age (P = .03) and high BMI (P = .04) were risk factors associated with abnormal HRR in patients with TIA. With regard to HRQOL, we found that role limitations due to physical problems, general health, vitality, and role limitations due to emotional problems were significantly lower in patients with abnormal HRR compared with patients with normal HRR. Multivariate analysis showed that older age (P = .04) and abnormal HRR (P = .03) were predictors for poor HRQOL in TIA patients.
HRR was impaired in patients with TIA. In addition, TIA patients with abnormal HRR suffered from a significantly poorer HRQOL. Hence, given the prognostic value of HRR, patients with TIA should be monitored to prevent cardiovascular events and to improve HRQOL.

Abstract
For benign and borderline tumors in the pancreatic neck and proximal body, laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and laparoscopic central pancreatectomy (LCP) are alternative surgical procedures. Choosing between LSPDP and LCP is difficult. This retrospective cohort study was looking forward to provide evidence for clinical decision.
A total of 59 patients undergoing LSPDP (Kimura procedure) and LCP between June 2013 and March 2017 were selected. The clinical outcomes of patients were compared by χ
2 test or Fisher exact test and Student t test.
This study included 36 patients in LSPDP group, and 23 patients in LCP group. The overall complications incidence in LCP group was significantly higher than LSPDP group (35 vs 6%, P = .004), and the postoperative pancreatic fistula (POPF) (grade B and C) rate and abdominal infection rate in LCP group were still significantly higher than LSPDP group (POPF 22 vs 3%, P = .019; abdominal infection 35 vs 3%, P = .001, respectively). The length of resected pancreas was significantly longer in LSPDP group (9.8 ± 2.0 vs 5.3 ± 1.1 cm, P = .007). The median follow-up was 39 months (range 12–57 months). No patient was confronted by tumor recurrence. The proportion of postoperative pancreatin and insulin treatment in LCP group were similar to LSPDP group (9 vs 17%, P = .383; 0 vs 3%, P = 1.000, respectively).
For patients with poor general condition, the safety of LCP needs to be taken seriously; in some ways, LSPDP may be more secure, physiological, and easier operation for tumor located in pancreatic neck and proximal body.

Abstract

Background:
Acute diarrhea is the 2nd highest prevalence disease among children under 5 years of age. It can cause malnutrition and even death in children, especially in developing country. Traditional Chinese medicine therapy has been applied and already in the guidelines for clinical practice of acute infectious diarrhea in children in China, but there is no specific methods or recommendations due to lacking of evidence. Zusanli acupoint injection as a form of acupuncture therapy, which is proved to be effective in randomised controlled trials (RCTs) and very suitable for children, has been used in acute diarrhea in children for a long time; therefore, a systematic review is necessary to provide available evidence for further study.

Methods:
Different studies from various databases will be involved in this study. Only RCTs of children under 5 years of age diagnosed with acute diarrhea using any recognized diagnostic criteria will be included. We will search manually the literature in the databases from China Conference Paper Database. Electronic database includes PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Internet, WanFang, Chongqing VIP, and China Biomedical Literature CDROM Database. Primary outcomes: clinical cure rate (clinical cure is defined as the frequency, timing and character of stool back to normal status, as well as disappearance of diarrhea symptoms), diarrhea duration (from admission to the cessation of diarrhea). Secondary outcomes: stool frequency within 24 hours, rate of adverse effect. Data will be extracted by 2 researchers independently; risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0.

Results:
This study will synthesize and provide evidence based on the data of the currently published zusanli (ST36) acupoint injection for acute diarrhea in children under 5 years old, especially in terms of clinical efficacy and safety.

Conclusion:
This systematic review aims to evaluate the benefits and harms of zusanli acupoint injection for acute diarrhea in children under 5 years old reported in RCTs, and provide evidence reference in TCM field for Chinese guidelines on the treatment of acute diarrhea in children.

Ethics and dissemination:
This study is a systematic review; the outcomes are based on the published evidence, and hence examination and agreement by the ethics committee are not required in this study. We intend to publish the study results in a journal or conference presentations.

Authors: Elkbuli Adel , Dowd Brianna , Flores Rudy , Boneva Dessy , McKenney Mark 
Published: August 2019

Abstract
Teaching status/academic ranking may play a role in the variations in trauma center (TC) outcomes. Our study aimed to determine the relationship between TC teaching status and injury-adjusted, all-cause mortality in a national sampling.
Retrospective review of the National Sample Program (NSP) from the National Trauma Data bank (NTDB). TCs were categorized based on teaching status. Adjusted mortality was determined by observed/expected (O/E) mortality ratios, derived using TRauma Injury Severity Score methodology from the Injury Severity Score and Revised Trauma Score. Chi-square and t test analyses were utilized with a statistical significance defined as P <.05.
Of the 94 TCs in the NSP, 46 were university, 38 were community teaching, and 10 were community nonteaching. For the University TCs, 62.8% were American College of Surgeons (ACS) level 1 and 81.2% state level 1. Of the community teaching TCs, 39.0% was ACS level 1 and 35.1% was state level 1. Of the community nonteaching TCs, 0% was ACS level 1 and 11.1% was state level 1. University TCs had a significantly higher O/E mortality rate than community teaching (0.75 vs 0.71; P = .04). There were no differences in O/E between community teaching and nonteaching TCs (0.71 vs 0.70; P = .70).
Community teaching and nonteaching TCs have lower injury-adjusted, all-cause mortality rates than University Centers. Future studies should further investigate key differences between University TCs and community teaching TC to evaluate possible quality and performance improvement measures.
Clinical trial to evaluate the efficacy of botulinum toxin type A injection for reducing scars in patients with forehead laceration
Authors: Kim Seong Hwan , Lee Seong Joo , Lee Jun Won , Jeong Hii Sun , Suh In Suck 
Published: August 2019

Abstract

Background:
Botulinum toxin type A (BoNTA) is known to prevent fibroblast proliferation and expression of transforming growth factor beta 1 (TGF-β1). It also induces temporary muscle paralysis and decreases tension vectors. Fibroblasts induce scar contracture and hypertrophy by producing collagen fibers in wound healing processes. The aim of this study is to identify the effect of BoNTA on the scar formation.

Methods:
Forty-five patients with forehead laceration were enrolled in this study and randomized into 2 groups with or without injection of BoNTA. When the patients presented to the clinic to remove the stitches, BoNTA was injected to the BoNTA group with 24 patients and saline was injected to the control group with 21 patients. The BoNTA was injected on dermal layer with 5 IU/cm. After that, follow-up was done in 1, 3, and 6 months. The scars were analyzed with the patient and observer scar assessment scale, Stony Brook scar evaluation scales (SBSESs), and visual analog scale (VAS) and analyzed with independent T-test, along with clinical photographs, cutometer, and biopsies.

Results:
In all scar scales, the scores changed into favorable direction in both groups and the changes were larger in BoNTA group compared with the control group. On SBSES and VAS, better improvements on BoNTA group showed statistical significance. Skin biopsy showed less collagen deposition on dermal layer in BoNTA group.

Conclusion:
Improvement of aesthetic, functional, and emotional aspect of the scar formation in the groups treated with BoNTA was illustrated. The application of BoNTA may be expanded to prevent hypertrophic scar after trauma, burns, or operations.
Efficacy of Juglandis semen complex extract for knee osteoarthritis
Authors: Kong Hae Jin , Kang Jae Hui 
Published: August 2019

Abstract

Background:
Knee osteoarthritis (KOA) is a common disease in elderly individuals. Many medications for KOA have the potential to cause side effects. We used Juglandis semen complex extract (JCE) consisting of 4 herbs derived from Cheong-A-Won, which has been commonly used for KOA treatment. In this study, we will evaluate whether JCE improves symptoms in patients with KOA and will identify the changes in the inflammation factor.

Methods:
This study will be a single-center, randomized, double-blind, and placebo-controlled trial. Three groups, JCE 1000 mg, 2000 mg, and placebo, will be randomly allocated. Total duration of the clinical trial will be 12 to 14 weeks. Study participants will be followed up every 6 weeks and the effect and safety will be assessed at the 2nd, 3rd, and 4th visit. All participants were asked to maintain a dosage schedule for this protocol. The primary outcomes will be measured using Korean Western Ontario and McMaster Universities Questionnaire and the secondary outcomes will include pain Visual analog scale score, EuroQol Five Dimensions questionnaire, Patient Global Impression of Change, and the changes in the laboratory test parameters of inflammation. Repeated-measure analysis will be used to measure primary efficacy based on full analysis set.

Discussion:
This study has limited inclusion and exclusion criteria and a well-controlled intervention, and it will be the first randomized controlled trial to assess the efficacy and safety of JCE in patients with KOA. This study provides insights into the mechanisms that explain the therapeutic effects of JCE in KOA and will lay the groundwork for further studies.

Published: August 2019

Abstract

Background:
Asthma is a complex disease associated with many factors such as immunologic, environmental, genetic, and other factors. Common medicines used to treat asthma include β-agonist and glucocorticoid. However, in the long-term treatment, the effect of the above-mentioned drugs is not satisfactory, so many patients choose oral Chinese medicines instead of western medicines. The introduction of Chinese medicines therapies, a rapid proliferation of the literature on management of asthma in general, call for novel ways of evidence synthesis in this area. This systematic review is to systematically summarize and evaluate a large number of evidences for Chinese herbal interventions for asthma. Evaluate the efficacy and safety of Chinese medicines in the treatment of asthma and inform a decision aid for the clinical encounter between patients and clinicians. In addition, it helps to establish a future research agenda.

Methods:
Five English databases (PubMed, Web of science, EBASE, Springer Cochrane Library, and WHO International Clinical Trials Registry Platform) and 4 Chinese databases (Wanfang Database, Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, and Chinese Biomedical Literature Database) will be searched normatively according to the rule of each database from the inception to the present. The literature screening, data extraction, and quality assessment will be conducted by 2 researchers independently. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. Asthma control test symptom score will be assessed as the primary outcome. The curative effect of single symptom and sign; Withdrawal and reduction of western medicines in a course of treatment, including: time, type, and quantity; Maintenance of western medicines after the course of treatment, including: type, quantity; Asthma Quality of Life Questionnaire; laboratory efficacy indexes as the secondary outcome. General physical examination; routine examination of blood, urine, and stool; electrocardiogram; liver and kidney function examination; possible adverse reactions and related detection indicators as the security indexes. Meta-analysis will be performed using RevMan5.3.5 software provided by the Cochrane Collaboration.

Results:
This study will provide high-quality synthesis based on current evidence of Chinese medicines treatment for asthma in several aspects, including asthma control score, side effects and laboratory examination such as lung-function test, serum total immunoglobulin, and so on.

Conclusion:
The results of this study will provide updated evidence for whether Chinese medicines is an effective and safe intervention for asthma.

Published: August 2019

Abstract

Background:
Overweight and obesity characterized by abnormal or excessive fat accumulation, can cause many complications. Auriculotherapy, as the traditional Chinese technique, is widely applied in clinical trials for the management of body weight. The program aims to evaluate the effect and safety of auriculotherapy therapy and intervention types on weight control.

Methods:
All randomized controlled trials related to auriculotherapy targeting overweight and obesity will be searched in online databases, such as Medline, EMbase, Cochrane Central Register of Controlled Trials, AMED, CBM, Wanfang Data, and other databases from their inception to July 2019. The primary outcome is the difference in BMI from baseline to the end of studies. Secondary outcomes include the change of weight, percentage of body fat, waist circumference, serum lipid before and after treatment. Study selection, data extraction, and assessment of risk of bias will be performed independently by 2 reviewers. Comprehensive Meta-Analysis software (Version 3; Biostat Inc.) will be used for data synthesis.

Results:
This study will provide a comprehensive review of the available evidence for the treatment of obesity with auriculotherapy.

Conclusion:
The conclusion of this study will provide evidence to judge whether auriculotherapy is an effective therapeutic intervention for obesity.

The clinical effects of antibiotic prophylaxis for hysteroscopic procedures
Authors: Guo Tao , Zeng Ni , Yang Jian , Wu Ping , Liu Pengpeng , Liu Zhisu , Cao Jun 
Published: August 2019

Abstract

Background:
Hysteroscopic procedures were widely applied but the clinical effects of antibiotic prophylaxis for these operations were not specifically addressed. In current study, we aimed to investigate the role of prophylactic antibiotics in hysteroscopic procedures by meta-analysis.

Methods:
We conducted literature retrieval in electronic databases, including MEDLINE, EMBASE, and Cochrane Central, to identify relevant randomized controlled trials (RCTs) investigating the clinical effects of antibiotic prophylaxis for hysteroscopic procedures. The postoperative infection rate was selected for pooled estimation. The I
2 index statistic was used to assess heterogeneity. Publication bias was evaluated using funnel plots and Egger test. Sensitivity analysis based on different subcategories was conducted to examine the stability of the main results.

Results:
Four RCTs including 2221 patients were identified for the final quantitative analysis. Pooled estimation indicated no significant difference in infection rate between the antibiotic prophylaxis group and control group (test for OR: Z = 0.50, P = .616; 95% CI: 0.987–1.008). Sensitivity analysis based on surgical procedure, antibiotic application, follow-up time and administration time revealed similar results.

Conclusion:
Based on current objective evidence, we conclude that antibiotic prophylaxis exhibits no clinical benefit for hysteroscopic procedures. Therefore, it is not recommended. Meanwhile, more high-quality RCTs are needed to support our conclusion.
Prognosis of synchronous colorectal carcinoma compared to solitary colorectal carcinoma: a matched pair analysis

Published: August 2019

Background
Synchronous colorectal carcinoma (CRC) is a specific and rare type of colorectal malignancy. The data on the impact of synchronous CRC are controversial. This study aimed to compare the characteristics and prognosis between synchronous CRC and solitary CRC.

Patients and methods
252 patients who underwent surgery between October 2009 and June 2013 with synchronous CRC (n = 126) or solitary CRC (n = 126) were included. The patients were matched according to age, sex, American Society of Anesthesiologists score, BMI, cancer grade, tumor location, and tumor stage. The short-term outcomes included the length of hospital stay, complications, and 30-day mortality. Long-term endpoints were overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS).

Results
The median follow-up duration for all patients were 42.5 months. The incidence of synchronous CRC was high than in older and male patients as well as in mucinous adenocarcinoma containing signet-ring cell carcinoma, tumor deposit, and polypus. The length of hospital stay after surgery was longer for synchronous CRC than solitary CRC (median: 10 vs. 4 days, P = 0.033). In multivariate analysis, synchronous CRC was an independent prognostic factor associated with poor OS (hazard ratio: 2.355, 95% confidence interval: 1.322–4.195, P = 0.004), DFS (hazard ratio: 2.079, 95% confidence interval: 1.261–3.429, P = 0.004), and CSS (hazard ratio: 2.429, 95% confidence interval: 1.313–4.493, P = 0.005).

Conclusion
The clinical and pathological features exhibit differences between synchronous CRC and solitary CRC and the prognosis of patients with synchronous CRC was poorer than those with solitary CRC.
