Objective To explore clinical characteristics of patients with cerebral infarction(CI) complicated with metabolic syndrome(MS) and their correlation with severity of cerebrovascular stenosis. Methods A total of 585 cases with CI were retrospectively studied. The patients were catogorized in to groups with and without MS according to NCEP-ATPⅢ diagnostic criteria. Severity of cerebrovascular were evaluated by CT. ResultsTwo hundred ninty cases(49.6%) complicated with MS showed higher body mass index (BMI), waist circumference, blood pressure, serum total cholesterol(TC), triglyceride (TG), uric acid (UA), fasting blood glucose (FBG), two hours postprandial blood glucose (2 h PBG), glucosylated hemoglobin A1c(HbA1c), and lower high-densitylipoprotein-cholesterol(HDL-C) than those without MS. Larger size and multiple infarcts and more serious score of neurological deficit were shown in patients complicated with MS. Severity of cerebrovascular disease disclosed by CT was positively related to levels of waist circumferene, blood pressure, TC, TG, HbA1c, FBG and 2 h PBG while in versely related to the levels of HDL-C (r=-1.23, P

Objective: To analysis the relationship between glucocorticosteroids (GCS) usage and side effects in the treatment of severe acute respiratory syndrome (SARS). Methods: All clinical records of probable SARS patients in Beijing were collected and input into an Epi6 database, in which 1 291 patients had entire information and met the clinical criteria of SARS. The usage of GCS and GCS associated side effects were analyzed retrospectively. Results: Patients accepted GCS therapy were 83.96% (n= 1 084), whereas 16.04%(n=207) did not take GCS. The average dosage of GCS was 160 mg/d in the first week, and then reduced to 80 mg/d and 40 mg/d in the second and the third weeks, respectively. Initial blood glucose, systolic pressure (SBP), and diastolic pressure (DBP) were no significant difference between GCS group and non-GCS group. The highest blood glucose during the treatment in GCS group was markedly higher than that in non-GCS group [(8.68? 4.80 ) mmol/L vs (6.39?3.71) mmol/L, P05). After GCS administration, SBP and DBP were increased gradually, and reached their peaks in the fourth week [SBP (117.2?14.0) mm Hg and DBP (72.5?9.1) mm Hg vs SBP (120.0?12.5) mm Hg and DBP (74.5?8.7) mm Hg, P

Objective To investigate the effects ofShipi-Gushen-Huayu Recipe on the expressions of collagen I, laminin(LN), transforming growth factor-β1(TGF-β1)andα-smooth muscle actin(α-SMA)in adriamycin-induced renal fibrosis in rats.Methods A total of male SD rats were randomly divided into four groups, with 10 rats in each group: a normal group, a model group, a treatment group and a fosinopril sodium group. Except the rats in the normal group, the rest rats were subjected to renal fibrosisvia tail intravenous injection of adriamycin(4 mg/kg). Two weeks after modeling, the rats in the rreatment group and in the fosinopril sodium group were intragastrically administrated daily withShipi-Gushen-Huayu Recipe extract(43 g/kg)and fosinopril solution(2 mg/kg), respectively,both in the normal group and model group with saline. After 30 days, 24-hours urine protein were determined, and the expressions of collagen I, LN, TGF-β1 andα-SMA in kidney tissue were detected with immunohistochemistry staining.Results The expressions of collagen I(24.64±0.67vs. 32.86±0.88), LN(18.71±0.72vs. 28.35±0.87), TGF-β1(14.71±0.68vs. 18.35±0.96)andα-SMA(17.64±0.74vs. 25.86±0.85)in the treatment group were significantly lower than those in the model group(allP<0.01). The expressions of collagen I, LN, TGF-β1 andα-SMA in the fosinopril sodium group were 27.33±0.73, 20.44±0.81, 15.44±0.85 and 19.33±0.77, respectively. There was no statistically significant difference between the expressions of collagen I, LN, TGF-β1 andα-SMA in the treatment group and in the fosinopril sodium group.ConclusionShipi-Gushen-Huayu Recipe can significantly down regulate the expressions of collagen I, LN, TGF-β1 andα-SMA in adriamycin-induced renal fibrosis in rats.

Objective: To explore the progression rate of cortid maximal plaque area and the risk of new ischemic cardiovascular disease (ICVD) in a rural cohort in Beijing.
Methods: The PRC-USA collaborative study had been regularly conducted in Shijingshan area in Beijing. The carotid ultrasound examination, ICVD risk factor and acute cardiovascular events follow-up were conducted in those participants. A total of 1479 subjects who received at least 2 carotid ultrasound examinations and had no cardiovascular disease before the second ultrasound were studied. They were divided into 5 groups:①Control group, the participants had no plaque detected by 2 ultrasounds; ② New plaque group, new plaque was found at the second ultrasound examination; ③ Plaque regression group; ④ Plaque stabilized group and ⑤ Plaque progression group. The hazard ratio (HR) between the progression rate of corotid maximal plaque area and new ICVD events was estimated by Cox proportional hazard regression analysis .
Results: Compared with Control group, the HR for new ICVD events were higher in groups②,③,④and⑤at 3.5, 5.7, 6.2 and 7.3 respectively, all P<0.05. The increasing trend of HRs remained signiifcant with the adjusted age and gender, P<0.001.
Conclusion: The progression rate of maximal corot id plaque area rate could predict the risk of new ICVD events in clinical practice.

We studied the effects of several medicinal insects on biosynthesis of polysaccharides from Ganoderma lucidum in submerged culture. The results showed that the medicinal insect, Catharsius molossus at 5 g/L significantly promoted the biosynthesis of intracellular polysaccharides (IPS) and extracellular polysaccharides (EPS) of G. lucidum, and compared with control, IPS and EPS yields markedly enhanced from (1.93 +/- 0.09) g/L to (2.41 +/- 0.12) g/L and (520.3 +/- 20.2) mg/L to (608.9 +/- 20.2) mg/L, respectively (P < 0.05). Both IPS and EPS consisted of five kinds of components, and IPS-1 and EPS-1 were the major components of IPS and EPS, respectively. Further separation studies showed that IPS-1 was made up of three single compounds, while EPS-1 was made up of two single compounds. There were no new components in both IPS and EPS obtained from G lucidum in submerged culture by the addition of the insect, C. molossus, suggesting the biosynthetic pathways of the major components of IPS and EPS had not been changed.

We studied the effects of Catharsius molossus (a Chinese medicinal insect) on the cell growth, fermentation kinetics of key bioactive substances and anti-cancer activity of Ganoderma lucidum in submerged fermentation. The results showed that C. molossus at all the tested concentrations had no stimulatory effect on the cell growth. However, addition of C. molossus at 5 g/L lead to significant effects on the fermentation kinetics of polysaccharides and triterpenoids of G lucidum, and at 7th day in fermentation process, the yields of polysaccharides and triterpenoids reached 2.81 g/L and 539.0 mg/L, respectively, while they were 2.25 g/L and 428.2 mg/L in control. In vivo anti-cancer studies showed that the inhibitory rates of control fermented G lucidum (CFG) and a combination of water extract from C. molossus and CFG on the developed tumor (Heps) in mice were 41.61% and 42.24%, respectively. Moreover, the inhibitory rate of the G lucidum fermented with C. molossus (GFC) reached 57.21%, which was enhanced 37.49%, compared to the inhibitory rate of the control fermented G lucidum. These results suggest that supplementation of C. molossus in submerged fermentation of G lucidum lead to a significant enhancement of the anti-cancer activity of cultured G lucidum.

Objective: To explore cyberbullying and risk factors of middle school students, and to provide a reference for cyberbullying prevention in school settings. Methods: A stratified cluster random sampling method was used to select 12 940 students from three junior high schools and four senior high schools in Yixing City of Jiangsu Province, China, to conduct a questionnaire survey from March 1 to May 31, 2019. The Chi -square test was performed to compare differences in the prevalence of cyberbullying among groups with different sociodemographic characteristics, and the multivariate Logistic regression model was employed to analyze the risk factors. A risk predictive nomogram model was constructed and then verified. Results: Middle school students were found to be victims of cyberbullying at a rate of 12.3%. The Logistic regression results showed that alcohol use ( OR =1.93), lack of emotional management ( OR =1.30), feeling unsafe ( OR =1.70), not trusting people ( OR =1.66), increased daily online time ( OR =1.39), higher frequency of using social software or websites ( OR =2.24), poor relationships with family members ( OR =1.46), parental neglect ( OR =1.50), class leadership ( OR =1.30) and poor relationships with classmates ( OR =1.34) were risk factors for middle school students who were victims of cyberbullying ( P <0.05). Based on these 10 independent risk factors, the nomogram prediction model, had good discrimination ( AUC =0.73). Conclusion Cyberbullying is common among middle school students. Internet use, parental neglect and class leadership all have an impact on cyberbullying.

Objective:To explore the mediating effect of smoking, emotional control, and family relationship on the association between relational bullying victimization and perpetration.Method:A total of 11 462 participants were included in the study. Mediating effect model was used to analyze the mediating effect of smoking, emotional control, and family relationship between relational bullying victimization and perpetration.Results:Family relationship (mediation effect value: 0.119, 95% CI: 0.075-0.165, mediation ratio: 8.5%) and smoking (mediation effect value: 0.061, 95% CI: 0.031-0.105, mediation ratio: 4.4%) constitute a separate mediating effect. Family relationship, emotional control, and smoking constitute a chain mediation effect (mediation effect value: 0.007, 95% CI: 0.003-0.013, mediation ratio: 0.5%); family relationship and smoking constitute a chain mediation effect (mediation effect value: 0.036, 95% CI: 0.020-0.056, mediation ratio: 2.6%); emotional control and smoking constitute a chain mediating effect (mediation effect value: 0.007, 95% CI: 0.003-0.013, mediation ratio: 0.5%). Conclusion:Smoking, emotional control, and family relationship partially mediate relational bullying victimization and perpetration.

【Objective】 To analyze the association of overweight and obesity with elevated blood pressure(BP) among children and adolescents in Mengzi City, in order to provide reference for making effective interventions. 【Methods】 A total of 30 classes of students in 14 schools were selected into this study by a stratified random cluster sampling method from October 2020 to September 2021. The paticipants completed a questionnaire survey, and had their height, weight and BP measured. Logistic regression analysis was used to evaluate the association of overweight and obesity with elevated BP. 【Results】 A total of 4 015 children and adolescents aged 7 - 17 years were involved in the study. The detection rate of overweight, obesity and elevated BP was 12.53%, 10.01% and 12.38%, respectively. The detection rate of elevated BP was 9.96%, 19.48% and 25.62% in normal weight, overweight and obese groups, respectively. The risk of elevated BP in the overweight and obese groups was 2.190 times(95%CI: 1.696 - 2.926, P<0.001) and 3.243 times(95%CI: 2.501 - 4.204, P<0.001) as high as that in normal weight groups. The dietary and exercise behaviors of 1 604 adolescents were analyzed, it was found that the detection rate of obesity was significntly higher in non-boarding students(15.09%) and those who consumed fresh fruits at least once a day(13.49%)(χ²=18.012, 7.225, P<0.05), the detection rate of elevated BP was significantly higher in among those who did not consume sugary beverages(16.88%), and performed moderate-to-high intensity physical exercise of 60 minutes or more ≤ 2 days per week(16.88%)(χ²=9.403, 14.921,P<0.01). 【Conclusions】 The risk of developing hypertension increases with the high prevalence of overweight and obesity and is strongly associated with multiple factors. Therefore, it is essential to conduct effective weight control and behavioral lifestyle interventions among children and adolescents.
