Objective: To investigate the expression of ciRS-7 in esophageal squamous cell carcinoma (ESCC) and its effect on the cellular proliferation, migration and invasion. Methods: The cancer tissues and paired adjacent normal tissues from 60 ESCC patients treated in the Fourth Hospital of Hebei Medical University between May, 2016 andApril, 2017 were selected for this study. The expressions of ciRS-7 were detected by qRT-PCR. After over-expressing or silencing of ciRS-7, the proliferation of ESCC cell line TE1 was measured by CCK-8 assay; and the migration and invasion were tested by wound healing assay and Transwell invasion assay,respectively. Finally, the effect was validated via animal experiment. Results: CiRS-7 was highly expressed in ESCC tissues (P<0.05), and its expression level was closely related to pathological grade and lymph node metastasis (P<0.05). Over-expression of ciRS-7 significantly increased the proliferation, migration and invasion (all P<0.05) of TE1 cells; while silencing of ciRS-7 remarkably suppressed the proliferation, migration and invasion (all P<0.05). Conclusion: CiRS-7 was up-regulated in ESCC and could enhance ESCC cell proliferation, migration and invasion, suggesting that ciRS-7 could be used as a potential target for the diagnosis and treatment of ESCC.

Objective:To investigate the atherosclerotic cardiovascular disease (ASCVD) risk and blood lipid level of occupational population in Xi'an and to provide reference for the prevention and treatment of cardiovascular diseases.Methods:Data of employees who came from 35 organizations and underwent physical examination in Xi'an city from March to December 2019 in Shaanxi Provincial People's Hospital were collected through cross-sectional investigation to evaluate ASCVD risk factors and compare their blood lipid level.Results:⑴ There were 8 806 subjects, including 7 104 males and 1 702 females. The highest risk factor exposure rates were overweight/obesity and smoking, accounting for 56.0% and 54.1%, respectively. The proportion of dyslipidemia was triglycerides (TG) (42.8%), total cholesterol (TC) (29.0%), high-density lipoprotein cholesterol (HDL-C) (16.2%) and low-density lipoprotein cholesterol (LDL-C) (16.1%). ⑵ According to the ASCVD risk assessment, the proportion of low risk, median risk and high risk were 77.7%, 12.9% and 9.4%, respectively. ASCVD risk was higher in men than in women, and the age ≥40 years group was higher than that of the age < 40 years group (all P<0.05). There were 530 cases taken risk assessment for rest of life, among which 283 cases were at high risk, accounting for 53.4%. ⑶ The average LDL value was (2.69±0.74)mmol/L, with a compliance rate of 78.4%. The average non-HDL value was (3.50±0.92)mmol/L, and the compliance rate was 70.1%. There was no significant difference in LDL and non-HDL compliance rates not only between the ASCVD risk groups, but also between the high-risk group and the non-high-risk group ( P>0.05). Conclusions:The occupational population in Xi'an has a large proportion of exposure to ASCVD risk factors, about 1/4 of which are ASCVD high-risk, and a better lipid control is expected to reduce the 10-year risk of ASCVD incidence.

【Objective】 To understand the prevalence of overweight and obesity in the professional population taking physical examination in Xi’an city so as to analyze the relationship of overweight and obesity with the unhealthy lifestyle and provide scientific evidence for the formulation of obesity management strategies. 【Methods】 A total of 10 616 professional subjects taking health examination were included in the study. Data concerning smoking, drinking, diet, sleep and night shift were collected through questionnaires; the subjects’ height and weight were measured and body mass index (BMI) was calculated. 【Results】 We recruited a total of 10 616 subjects in this study, of whom 8 320 (78.8%) were males and 2 296 (21.1%) were females. The total overweight rate in the study population was 40.8%, with 46.6% for males and 19.6% for females. The total obesity rate was 14.3%, among which 16.8% was for males and 5.0% for females. The overweight rate and obesity rate of males were both significantly higher than those of females (P<0.05). There was a linear correlation of BMI with smoking, drinking, eating habits (vegetarianism, sweet and meat intake), sleeping time, and night shift frequency (P<0.05). There was a grade correlation between exercise frequency and BMI. BMI increased with the increase of exercise frequency (P=0.017). The results of multiple Logistic regression analysis on the influence of different factors on overweight/obesity showed that male, age and meat preference were independent risk factors for overweight, while vegetarianism was the protective factor for overweight. Male, age, smoking, meat preference, and night shift ≥2 times/week were independent risk factors for obesity, while vegetarianism and exercise≥3 times/week were the protective factors. 【Conclusion】 The overweight/obesity rate of males is higher than that of female in Xi’an city. Unhealthy lifestyle such as smoking, meat preference and night shift ≥2 times/week are independent risk factors for obesity, while vegetarian diet and regular exercise habits are conducive to weight management.

OBJECTIVE To investigate the risk factors for tigecycline -induced hypofibrinogenaemia by systematic review . METHODS The literature about risk factors for tigecycline -induced hypofibrinogenaemia were retrieved from English databases (PubMed,Cochrane Library ,Embase,Web of Science )and Chinese databases (CNKI,Wanfang Database ,VIP,CBM)during the inception to Feb . 5th,2022. At the same time ,the unpublished clinical trial data were additionally searched . After the quality evaluation of the included literature was carried out by adopting the Castle -Ottawa Scale (NOS),data were extracted from the literature that met the inclusion criteria ,and Meta -analysis was conducted by using RevMan 5.3 software. RESULTS Finally,8 literature were selected ,with a total of 1 374 cases,including 706 cases in the trial group and 668 cases in the control group . There were 4 Chinese and 4 English literature ,all of which were case control studies published between 2017-2021. Meta-analysis showed that the risk factors for tigecycline -induced hypofibrinogenaemia were age [OR=1.04,95%CI(1.02,1.06),P=0.000 5],baseline fibrinogen level [OR=0.54,95%CI(0.42,0.69),P<0.000 01],abdominal infection (sensitivity analysis )[OR=9.43,95%CI(4.24, 20.95),P<0.000 01],dose each time [OR=2.87,95%CI(2.04,4.02),P<0.000 01],medication time [OR=1.10,95%CI(1.00, 1.22),P=0.04]. CONCLUSIONS Advanced age ,low baseline fibrinogen levels ,abdominal cavity infection ,relative high dose each time and slightly long medication time are potential risk factors for tigecycline -induced hypofibrinogenaemia . If the above risk factors exist ,it is suggested to pay close attention to the occurrence of hypofibrinogenaemia in the course of tigecycline administration.

Objective: To investigate the effect of miR-124 on the invasion and migration of esophageal cancer KYSE170 cells by regulating autophagy. Methods: miR-124 mimic was transfected into esophageal cancer KYSE170 cells. Transwell assay was used to detect the change of invasion and migration ability of cells. Dual luciferase reporter gene assay was used to verify the targeted regulation of BECN1 (Beclin1) by miR-124, and Western blotting was used to analyze the expressions of BECN1, P62 and LC3 protein. siRNA targeting BECN1 was transfeted into KYSE170 cells, and then the cell invasion and migration ability was calculated by Transwell assay. The expressions of BECN1, P62 and LC3 protein were detected by Western blotting. miR-124 mimic and BECN1 over-expression plasmid were co-transfected into KYSE170 cells, and then Transwell assay was used to detect the changes of cell invasion and migration ability, and Western blotting to examine the expression levels of autophagy-related gene. Results: The invasion and migration ability of KYSE170 cells were significantly inhibited after transfection with miR-124 mimic (All P<0.05). The expression of autophagyrelated protein P62 was increased, and the expression of BECN1 and LC3 was significantly decreased (All P<0.01); in addition, the activity of luciferase reporter gene was also significantly reduced (P<0.01). Silencing BECN1 expression inhibited the invasion and migration of esophageal cancer KYSE170 cells (P<0.01). However, after co-transfection with BECN1 over-expression plasmids, the effects of miR-124 mimic on the autophagy, invasion and migration of esophageal carcinoma KYSE170 cells were significantly weakened (P<0.01), it was also accompanied with lower P62 expression, and higher LC3 expression (P<0.01). Conclusion: miR-124 mimic can inhibit the invasion and migration of esophageal carcinoma cells. The mechanism may be related to the autophagy-related gene BECN1 expression.
