Objective: To conduct the integrated management of hospital, community and family for patients with insulin injection at home, in order to explore the influence of this trinity health education model on the knowledge of medical waste and the standard disposal of discarded needles. Methods: The self-designed questionnaire was used to investigate the knowledge and disposal of medical waste in outpatients, and the causes were analyzed carefully after the problems were found. The hospital, community and family were timely communicated and fed back to the ward and community. After 1, 3 and 6 months of educational intervention, the disposal of insulin needles, the knowledge of medical waste and the recovery of sharp instrument boxes were observed. Results: After 1, 3 and 6 months of health education, the final rate of insulin needles mixed into domestic waste was 51.8% (144/278), 15.1% (42/278) and 4.7% (13/278), respectively. Compared with the first result of 99.6% (277/278), the difference was statistically significant (χ²=173.046, 406.136, 502.346, P<0.01); The first survey found that the correct rate of responding to medical waste knowledge items was low. After health education for 1, 3 and 6 months, the correct rate of medical waste related knowledge items was significantly higher than that of the first survey, and the difference was statistically significant (OR=3.016-3 548.810; 95%CI 2.108-917.869, 4.315-19 777.062; χ²=25.180-524.895; P<0.01) ; After 1, 3 and 6 months of health education, the qualified rate of medical waste knowledge was 82.4% (229/278),75.9% (211/278) and 97.1% (270/278), respectively, which was significantly higher than the first result of 6.5% (18/278). The difference was statistically significant (χ²=324.328, 273.712, 453.832, P<0.01). The sharp box recovery of hepatitis B patients was relatively good. Conclusion Hospital-community-family Trinity health education model can improve the breadth and depth of education objects, not only can improve the knowledge of medical waste related to insulin injection patients at home, but also can improve the standardized disposal ability of insulin waste needles. With the passage of time, the effect of health education continues to be good. This integrated health education model is worth popularizing in clinic.

Curriculum integration has become the core content of the current medical education reform.With the rapid development of information technology,how to reflect the teaching and learning effects and to further improve them,is one of the difficulties in the reform of the integrated curriculum.In view of the problems of single form of assessment model,separate classroom teaching and extracurricular teaching evaluation,low utilization of network and electronic teaching resources,we make full use of network methods to carry out reform on the current formative teaching evaluation system.With the purpose of formative assessment and evaluation,the "Blackboard network teaching system" of the curriculum has been built,and the evaluation indexes of classroom teaching and extracurricular teaching have been established.And at the same time,the formative assessment index has been enriched and perfected in a diversified form,and the formative assessment model adapted to the integrated curriculum is preliminarily explored.

Objective: To explore the effect of ligustrazine on the LPS-induced apoptosis and inflammatory response of osteoarthritis chondrocytes. Methods: Osteoarthritis model was induced by LPS. Chondrocytes were divided into four group: control group, ligustrazine ( 20 μmol/L) group, LPS ( 100 ng/ml) group and ligustrazine ( 20 μmol/L) +LPS ( 100 ng/ml) group. Apoptosis was measured by Hoechst33258 staining. The levels of nitric oxide ( NO), tumor necrosis factor α ( TNF-α) and interleukin ( IL) -6 were detected by ELISA. The protein levels of collagenⅡ, aggrecan, matrix metalloproteinase 13 ( MMP-13), NF-κB P65 and p-NF-κB P65 were tested by Western blot. Results: The LPS-induced abnormal cell morphology and decreased number of cells were ameliorated by ligustrazine ( 20 μmol/L). The apoptosis in LPS group was higher than control group ( P＜0. 05). The LPS-induced enhancive apoptosis was reduced by ligustrazine ( P＜0. 05). Compared with control group, the expression of collagenⅡ and aggrecan was alleviated with increased expression of MMP-13 ( P＜0. 05). The LPS-induced declined expression of collagenⅡ and aggrecan and elevated expression of MMP-13 was inhibited by ligustrazine ( P＜0. 05). The levels of NO, TNF-α and IL-6 in LPS group were higher than control group ( P＜0. 05). The levels of NO, TNF-α and IL-6 in LPS+ligustrazine group were lower than LPS group ( P＜0. 05). Compared with control group, the rate of pP65/P65 in LPPS group was enhanced ( P＜ 0. 05). The LPS-indiced increased rate of p-P65/P65 was decreased by ligustrazine ( P ＜0. 05). Conclusion: Ligustrazine alleviates the LPS-induced apoptosis and inflammatory response of osteoarthritis chondrocytes via inhibiting phosphorylation of NF-κB P65.

The mammalian central nervous system (CNS) is considered an immune privileged system as it is separated from the periphery by the blood brain barrier (BBB). Yet, immune functions have been postulated to heavily influence the functional state of the CNS, especially after injury or during neurodegeneration. There is controversy regarding whether adaptive immune responses are beneficial or detrimental to CNS injury repair. In this study, we utilized immunocompromised SCID mice and subjected them to spinal cord injury (SCI). We analyzed motor function, electrophysiology, histochemistry, and performed unbiased RNA-sequencing. SCID mice displayed improved CNS functional recovery compared to WT mice after SCI. Weighted gene-coexpression network analysis (WGCNA) of spinal cord transcriptomes revealed that SCID mice had reduced expression of immune function-related genes and heightened expression of neural transmission-related genes after SCI, which was confirmed by immunohistochemical analysis and was consistent with better functional recovery. Transcriptomic analyses also indicated heightened expression of neurotransmission-related genes before injury in SCID mice, suggesting that a steady state of immune-deficiency potentially led to CNS hyper-connectivity. Consequently, SCID mice without injury demonstrated worse performance in Morris water maze test. Taken together, not only reduced inflammation after injury but also dampened steady-state immune function without injury heightened the neurotransmission program, resulting in better or worse behavioral outcomes respectively. This study revealed the intricate relationship between immune and nervous systems, raising the possibility for therapeutic manipulation of neural function via immune modulation.

OBJECTIVE: Obesity is recognized as a significant risk factor for diabetes and hypertension. The present study aimed to examine the associations between adults'obesity risk and childhood and parental obesity. METHODS: A total of 204 children aged 6-17 years were recruited in 2002 with an average follow-up period of 13.2 years. Height and body weight were measured by trained staffs. Overweight and obesity were defined based on the Chinese standard for children and adults. T-test, analysis of variance, and Chi-square analysis were used for single factor analysis. Multiple linear and logistic regression analyses were used to perform multifactor analysis. RESULTS: The percentage of non-obese children who grew up to be non-obese adults was 62.6%, and that of obese children who grew up to be obese adults was 80.0%. There was a significant association between childhood body mass index (BMI) and adulthood BMI with a β regression coefficient of 3.76 [95% confidence interval (CI): 1.36-6.16], and between childhood obesity and adulthood obesity with an odds ratio of 5.76 (95% CI: 1.37-24.34). There was no statistical difference between parental obesity at baseline and children's adulthood obesity, after adjustment of confounders. Male participants and those aged 10.0-13.0 years had a higher risk of adulthood obesity with odds ratios of 2.50 (95% CI: 1.12-5.26) and 3.62 (95% CI: 1.17-11.24), respectively. CONCLUSION Childhood obesity is an important predictor of adulthood obesity.

Rhizosphere bacteria play a vital role in plant nutrition absorption,growth and disease resistance. In this study,high-throughput sequencing technology was used to analyze the rhizosphere bacterial communities of Salvia miltiorrhiza and S. miltiorrhiza f. alba. Moreover,the function of dominant rhizosphere bacterial communities was analyzed. We found that Sphingobacteriales,Sphingomonadales and Nitrosomonadaceae were both dominant and specific bacteria in the rhizosphere of S. miltiorrhiza. The main functions of dominant rhizosphere bacteria communities in both species include promoting transformation of soil nutrients,improving plant immunity and ability of stress tolerance. This study was the first to compare rhizobacterial communities structure and function of S. miltiorrhiza and S. miltiorrhiza f. alba,which provided a new theoretical reference for studing the rhizosphere mechanism of healthy S. miltiorrhiza planting in the future.

Objective To explore factors influencing the incidence of carotid atherosclerosis in different genders so as to provide reference for the specific prevention of the disease. Methods A nested case-control study was conducted to analyze factors influencing the incidence of carotid atherosclerosis in Jinchang cohort population who were randomly selected through stratified sampling by age and followed up. A risk prediction model was established and the goodness of fit was evaluated by the area under the receiver operator characteristic curve (ROC). Results The standardized incidence of carotid atherosclerosis in this follow-up population was 12.32%, and the incidence rate of males (13.65%) was greater than that of females (11.29%). The difference was statistically significant ( 2=4.267, P<0.001). Age, education, elevated systolic blood pressure, and elevated low-density lipoprotein cholesterol were common risk factors for carotid atherosclerosis in both men and women. Elevated fasting plasma glucose (OR=2.556, 95% CI: 1.618-4.038) and elevated triglyceride (OR=1.535, 95% CI: 1.058-2.227) were only associated with men. Abdominal obesity (OR=1.414, 95% CI: 1.013-1.974) was only associated with women. The area under ROC of male and female prediction models was 0.835 (95% CI: 0.815-0.856) and 0.809 (95% CI: 0.788-0.831), respectively. The sensitivity was 78.0% and 78.9%, the specificity was 78.8% and 73.1%, and the diagnostic coincidence rate was 91.3% and 82.4%, respectively. Conclusions There are different risk factors for carotid atherosclerosis in males and females, and targeted prevention and control measures should be taken according to gender. The risk prediction model established by Logistic regression had certain guiding value.

Objective: To observe effect of Mori Folium-containing serum on glucose consumption and cell activity of fat cell line 3T3-L1 insulin resistance (IR) model, in order to screen out the optimal concentration of drug-containing serum, detect effect of Mori Folium on the content of inflammatory factors, and explore the possible mechanism. Method: 3T3-L1 preadipocytes in logarithmic growth phase were selected, and induced with 10 mg·L^-1 insulin (Ins), 0.25 mmol·L^-1 dexamethasone (DEX) and 0.5 mmol·L^-1 3-isobutyl-methylxanthine(IBMX) for 48 h and then with 10 mg·L^-1 Ins for 48 h. After the cells were differentiated into mature adipocytes, they were induced with 1 μmol·L^-1 DEX for 96 h to establish IR model. Glucose content in the supernatant of cells was detected by glucose oxidase after serum containing Mori Folium cultured for 12,24,36, 72 h. Methyl-thiazdyl-tetrazolium(MTT) was used to detect the effect of serum containing Mori Folium on IR cells activity. The content of tumor necrosis factor-α(TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA). Meanwhile, the effects of inflammatory factors on the expressions of insulin signaling pathway proteins insulin receptor (InsR), insulin receptor substrate (IRS), p-IRS1 and glucose transporter 4 (GLUT4) were determined by Western blot. Result: Serum containing Mori Folium could significantly increase the glucose consumption rate and cell activity of IR cells (P<0.01), reduce the content of TNF-α (P<0.01), and regulate the expression of insulin signaling pathway proteins (P<0.05,P<0.01). Conclusion: Mori Folium can significantly improve IR status of 3T3-L1 cells, and its mechanism may be related to inhibiting TNF-α and promoting the expressions of insulin signaling pathway proteins.

BackgroundFunctional dyspepsia (FD) is a common upper gastrointestinal disorder worldwide, but the current treatments for FD are still unsatisfactory. The aims of this study were to investigate the efficacy and safety of Qi-Zhi-Wei-Tong granules in patients with postprandial distress syndrome (PDS)-predominant FD.

MethodsThe study was conducted as a randomized, double-blinded, multicenter, placebo-controlled design in 197 patients with PDS. All participants received placebo treatment for 1 week. Patients whose total symptom score decreased by <50% after the placebo treatment were recruited into the 4-week treatment period, in which they were randomly assigned to be treated with either Qi-Zhi-Wei-Tong granules or placebo. The patients were then followed for 2 weeks without any treatment. Dyspeptic symptoms were scored at weeks 2 and 4 during the random treatment period and 2 weeks after the treatment. Anxiety and depression symptoms were also scored and compared.

Results(1) The total effective rates in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 during the random treatment period and 2 weeks after treatment were all significantly higher than those in the placebo group (38.82% vs. 8.75%, P < 0.001; 69.14% vs. 16.25%, P < 0.001; 77.65% vs. 21.25%, P < 0.001). (2) The total dyspeptic symptoms scores in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 and 2 weeks after treatment were significantly lower than those in the placebo group. (3) The severity and frequency of each dyspeptic symptom at weeks 2 and 4 and the follow-up period were all significantly lower than those in the placebo group. (4) The anxiety scores in the Qi-Zhi-Wei-Tong granules group were significantly lower than those in the placebo group. (5) Qi-Zhi-Wei-Tong granules did not have more adverse effects than the placebo.

ConclusionQi-Zhi-Wei-Tong granules offer significant symptomatic improvement in PDS with no more adverse effects than placebo.
