Objective:To assess the relationship between appendicular skeletal muscle mass (ASM) and ankle brachial index (ABI) among patients with type 2 diabetes.Methods:In this cross-sectional study, from July 2018 to March 2019, a total of 278 patients with type 2 diabetes treated in Zhongda Hospital were enrolled in this study, and there were 158 males and 120 females. General information and clinical biochemical parameters and ABI in the patients were collected. The appendicular muscle mass was quantitatively measured with body composition analyzer to achieve ASM. And the appendicular skeletal muscle mass index (ASMI), skeletal muscle index (SMI), and appendicular skeletal muscle mass/body mass index (ASM/BMI) were calculated respectively. Correlation analysis and multiple linear regression analyses with different adjustment models were conducted to analyze the correlation between ABI and above-mentioned indexes.Results:The Pearson correlation analysis showed that ABI had significant positive correlation with ASM, ASMI and ASM/BMI ( r=0.14, 0.13, 0.13, all P<0.05), but a marginal relation with SMI ( r=0.116, P=0.053). Multiple linear regression analysis suggested that ASMI ( β=0.053, 95% CI: 0.006-0.101, P=0.027) and AMI/ABI ( β=0.347, 95% CI: 0.040-0.654, P=0.027) were significantly related to ABI. Conclusion:ASM is positively associated with ABI in patients with type 2 diabetes.

Immune checkpoint therapy is a new mode of tumor therapy. At present, many kinds of PD-1/PD-L1 inhibitors have been approved for clinical application on various tumors, such as malignant melanoma, lung cancer, bladder cancer, lymphoma, etc. However, with the gradual promotion and application in clinical practice, various immune-related adverse reactions caused by PD-1/PD-L1 inhibitors have attracted extensive attention. Especially in recent years, a number of adverse reactions related to endocrine gland injury have been reported. This paper reviews the research status and corresponding clinical treatment methods of endocrine gland related adverse reactions caused by PD-1/PD-L1 inhibitors.

Objective: To investigate the frequency of KRAS mutation in mucinous epithelial lesions of the endometrium, and analyze the correlation between KRAS mutation and the clinicopathologic features. Methods: The cohort included forty-three cases of mucinous epithelial lesions of the endometrium selected from July 2015 to October 2017 from Beijing Obstetrics and Gynecology Hospital, and 22 control cases. Genomic DNA was extracted from formalin-fixed paraffin-embedded tissue sections. Polymerase chain reaction amplification for KRAS exons 2 and 3 was performed, followed by sequencing using capillary electrophoresis. The Fisher exact test was used to compare the prevalence of KRAS mutation among the different groups. Results: The patients′age ranged from 33 to 77 years [mean (55.12±9.34) years, median 55 years]. None of the eight cases of endometrial hyperplasia with mucinous differentiation without atypia showed KRAS mutation. The frequency of KRAS mutations was 1/10 in endometrial atypical hyperplasia, 1/12 in endometrioid carcinoma, 4/11 in endometrial atypical hyperplasia with mucinous differentiation (EAHMD), 6/15 in endometrioid carcinoma with mucinous differentiation (ECMD) and 8/9 in mucinous carcinoma (MC), respectively. The differences were statistically significant between MC versus EC (P<0.01) and MC versus ECMD (P<0.05). Conclusion The high frequency of KRAS mutation in EAHMD, ECMD and MC indicates that KRAS mutational activation is implicated in the pathogenesis of endometrial mucinous carcinoma.

Objective To verify the antiviral effects of Siji Kangbingdu mixture (SJKBDM) against coxsackievirus A16 (CoxA16).Methods Vero cells and 5-day-old suckling mice, injected with 75/50 and 1×106 TCID50 CoxA16, were used as evaluation models.The preventive influences of SJKBDM against CoxA16 in Vero cells were assessed in the models.The effects of SJKBDM on the mortality, survival time, change rate of body weight, and clinical symptom scores of suckling mice were observed.Results ①The half maximal inhibitory concentration of SJKBDM on Vero cells was 9.59 mg·mL-1.②Toxic effects were not observed from 32.3 g·kg-1 single dose or continuous intraperitoneal injectin of SJKBDM in suckling BALB/c mice.③The SJKBDM had significant inhibitory effect against CoxA16 virus.Doses higher than 1.22 mg·mL-1 could significantly improve the Vero cell survival rate, and the SJKBDM inhibition of 75/50 TCID50 CoxA16 induced pathological changes in Vero cells.④The SJKBDM significantly improved clinical symptoms of mice with CoxA16 viral infection, especially with crude drug doses of higher than 1.62 g·kg-1.The survival rate and other indicators were comparable or slightly higher compared with ribavirin, and the clinical score was higher than that of ribavirin.Conclusion The SJKBDM has significant inhibitory effect on CoxA16 cell proliferation, significantly decreases death rate, and improves clinical symptoms of mice infected with CoxA16 virus.

OBJECTIVE: To assess and compare the two procedures, total thyroidectomy (TT) and partial thyroidectomy (PT), for papillary thyroid cancer in terms of associated injuries, postoperative complication, recurrence rate and survival, so as to provide a reference and basis for surgical procedure option of this disease. METHOD: Strictly specified into the exclusion criteria, the combination of computer retrieval and manual retrieval and retrieval systems such as CNKI, Wang Fan, PubMed, central, CBM database. Total thyroidectomy and partial thyroidectomy for the treatment of patients with thyroid papillary cancer related literature were compared, with the retrieval time until December 31, 2013. RESULT: According to the retrieval strategy 4630 literatures were found, and 20 witch matched the exclusion criteria were left, all were retrospective study. TT and PT group of recurrent laryngeal nerve injury rate are 5.9%, 2.0% respectively [OR = 0.39, 95% CI (0.17 - 0.90), P < 0.05], TT and PT group of parathyroid injury rate are respectively 4.9%, 0.8% respectively [OR = 0.23, 95% CI (0.08 - 0.68), P < 0.01]. The TT group of 10 years survival rate is 95.24% - 100%, and the PT group is 96.8% - 99.2% [OR = 0.03, 95% CI (0 - 0.34), P < 0.01]. Unstaged, unstaged TT group' postoperative recurrence rate is 4.7%, while PT group is 12.6% [OR = 3.21, 95% CI (1.57 - 6.57), P < 0. 01]. Postoperative recurrence of stage I TT group and PT group are 4.9%, 7.8% respectively [OR = 3.82, 95% CI (1. 07-13.66) P < 0.05]; The rate of stage II TT group is 0.5%, while the rate of PT group is 15.9% [OR = 17.23, 95% CI (4.03 - 73.73), P < 0.01]. CONCLUSION Different methods of primary thyroid papillary carcinoma surgical treatment can all obtaina good survival, but the rate of laryngeal recurrent nerve injury and parathyroid injury caused by partal throidectomy is relatively lower. As a result, partial thyroidectomy can be a good choice for early stage thyroid papillary carcinoma.

Objective To evaluate the accuracy of realtime polymerase chain reaction (PCR) assay in the detection of group B Streptococcus (GBS) in pregnant women. Methods Samples were collected from 1 395 women at 35-37 weeks of gestation from March 1 to December 31, 2009 at three hospitals in Beijing. Samples were obtained from the lower one third vaginal wall and perianal area and tested for GBS using standard culture and PCR. Standard culture and gene analysis for GBS were applied as the gold standard, and the sensitivity and specificity of the rapid assay were determined. Results Of the 1 395 women qualified for PCR testing, 40(2.9%) were identified as GBS positive on the basis of the results of specimen culture, compared to 114 (8.2%) on the basis of PCR assay. The culture was negative and the PCR positive in 77 patients. The results which were not in agreement using the two tests were evaluated by the gene analysis for GBS. Among the 77 samples which were GBS positive by PCR, 66 samples were determined as GBS positive by gene analysis. The sensitivity of the PCR assay was 97.2%(103/106) and specificity was 99.1%(1 278/1 289), the maternal GBS colonization was 7.6%(106/1 395). Conclusions Realtime PCR assay allows rapid and reliable detection of GBS in last trimester with high sensitivity and specificity.

Regular physical activity (PA) is a key element in the prevention and management of type 2 diabetes mellitus (T2DM). Participation in regular PA improves blood glucose control and can prevent or delay T2DM and its complications, along with positively affecting lipids, blood pressure, cardiovascular events, mortality, and quality of life. However, most people with T2DM are not active and show poor adherence. This paper reviews the possible barriers to PA and strategies to improve the adherence to PA. Based on the currently available literature, it is concluded that self-efficacy and social support from family, friends, and health care providers play the important role in adoption and maintenance of regular PA. Here we also highlight some new modern and innovative interventions that facilitate exercise participation and improve the adherence.
