【Objective】 To explore the influencing factors of adolescent runaway and its correlation with family health so as to provide epidemiological evidence for future comprehensive interventions. 【Methods】 Using the quota sampling method, 1 065 adolescents aged 12-18 years old were surveyed by Questionnaire Star in 120 cities in China from July to September 2021. A well-developed electronic questionnaire was used to collect information about demographic characteristics, psychological characteristics, family health, social support, and behavior of running away from home. Univariate analysis and Logistic regression were used to explore the influencing factors of adolescent runaway and its correlation with family health. 【Results】 A total of 1 065 adolescents were investigated, among whom 334 were the only children (31.36%) and 442 were boys (41.50%). Univariate analysis revealed that 7.6% of teenagers had the experience of running away from home in the last 30 days. Participants who were ethnic minorities (P=0.031) and had education of technical school or junior college (P=0.029) and a low family income (P<0.001) were more likely to have running away behavior. Adolescents with low self-efficacy (P=0.005), depression (P<0.001), anxiety (P<0.001), and more stress had higher detection rates of runaway behavior. However, adolescents with higher family health and social support were less likely to run away from home (P<0.01). Multivariate analysis showed that compared with adolescents with low family health, adolescents with high (OR=0.16, 95% CI: 0.06-0.46) and moderate (OR=0.27, 95% CI: 0.14-0.55) family health had a significantly lower risk of runaway behavior. 【Conclusion】 The family is of great significance in preventing teenagers from running away from home. Parents should build a good parent-child relationship and create a happy family atmosphere to reduce the occurrence of teenagers running away from home.

【Objective】 To explore the effects of perceived risk of COVID-19 of college students on their anxiety and depression, as well as the roles of attention to negative information and perceived social support, so as to provide theoretical basis for colleges and universities to formulate corresponding intervention measures. 【Methods】 By the convenience sampling method, totally 1 404 college students from Shaanxi and Henan provinces were investigated online by using General Information Questionnaire, Perceived Risk of COVID-19 Pandemic Scale, Attention to Negative Information Scale, Patient Health Questionnaire, Generalized Anxiety Disorder and Perceived Social Support Scale. SPSS 20.0 was used for data analysis, Pearson correlation method was used to explore the correlation between variables. The mediating effect of attention to negative information and the moderating effect of perceived social support were analyzed by PROCESS. 【Results】 The scores of anxiety and depression of the 1 404 college students included in the study were 4.03±4.48 and 6.21±5.41, respectively. The detection rate of anxiety symptom was 29.9%, and that of depression symptom was 44.4%. The risk perception of COVID-19 epidemic of the college students was positively correlated with attention to negative information (r=0.373, P<0.001), anxiety (r=0.227, P<0.001), and depression (r=0.226, P<0.001). Anxiety (r=0.553, P<0.001) and depression (r=0.497, P<0.001) were positively correlated with attention to negative information, while perceived social support was negatively correlated with the risk perception of the COVID-19 (r=-0.154, P<0.001), attention to negative information (r=-0.259, P<0.001), anxiety (r=-0.321, P<0.001) and depression (r=-0.278, P<0.001). The risk perception of COVID-19 affected the anxiety and depression of the students mainly through the mediating effect of attention to negative information. The total effect of risk perception of COVID-19 and anxiety was 0.227, and the mediating effect accounted for 80.18% of the total effect. The total effect of risk perception of COVID-19 and depression was 0.228, and the mediating effect accounted for 90.35% of the total effect. Perceived social support played a moderating role in the last half of this mediating model. 【Conclusion】 Risk perception of COVID-19 indirectly affects the occurrence of anxiety and depression in college students through attention to negative information, and perceived social support plays a moderating role in this mediating model. The findings suggest that when a risk event occurs, colleges and universities should pay attention to guiding students to adjust their attentional bias to external information, and give students enough care and support to improve their mental health.

【Objective】 To explore the relationship between chronic comorbidity and the physical and mental health of relatives of elderly people during the nursing home confinement, and to analyze the mediating effects of perceived stress and intolerance of uncertainty in this context. 【Methods】 A total of 568 family members of elderly people in nine elderly institutions in Shaanxi Province were selected. The survey included the short version of the Perceived Stress Scale, Intolerance of Uncertainty Scale, and The World Health Organization-5 Well-being Index. The data were analyzed with Stata for correlation and mediation effects. 【Results】 ① The comorbidities of chronic diseases was positively correlated with the perceived stress (r=0.16, P<0.001) and intolerance of uncertainty (r=0.11, P=0.006) of the family members, but negatively correlated with the physical and mental health of the family members (r=-0.13, P=0.002). ② The mediating effect of perceived stress between chronic disease co-morbidity and physical and mental health of family members in older adults was -0.023, accounting for 18.8% of the total effect; the mediating effect of intolerance of uncertainty between chronic disease co-morbidity and physical and mental health of family members in older adults was -0.041, accounting for 33.5% of the total effect. 【Conclusion】 During closed management in a nursing facility, the physical and mental health of family members of older adults with chronic co-morbidities is poorer than that of family members of non-chronic co-morbidities. And it can lead to a decline in physical and mental health of family members through increased perceived stress and intolerance of uncertainty.

ObjectiveTo investigate the effect of entecavir (ETV) antiviral therapy on the prognosis of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) receiving transcatheter arterial chemoembolization (TACE). MethodsA total of 170 HCC patients who received TACE for the first time in Liver Cancer Center of Nanfang Hospital from January 2011 to March 2018 were enrolled, among whom 114 patients were treated with ETV (ETV treatment group) and 56 patients did not receive antiviral therapy (control group). Baseline demographic data, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), albumin (Alb), platelet count (PLT), Child-Pugh class, HBeAg and HBV DNA levels, alpha-fetoprotein, and BCLC stage were recorded before treatment, and the changes in HBV DNA level, ALT, AST, TBil, Alb, and Child-Pugh class were observed at weeks 4-8 after treatment; long-term survival was also observed after treatment. Short- and long-term clinical benefits (overall survival) were observed for all patients. The t-test or the Wilcoxon signed-rank test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. Multivariate logistic regression analyses were performed for related clinical indices before treatment to identify the risk factors for HBV reactivation. The Kaplan-Meier method was used to analyze the survival curves of overall survival, and the log-rank test was used for comparison of survival curves. ResultsThere was no significant difference in the incidence rate of HBV reactivation between the ETV treatment group and the control group (15.79% vs 16.07%, χ2=0.002，P=0.962). The univariate analysis showed that PLT was a risk factor for HBV reactivation (Z=-2.183,P=0.029), and the multivariate analysis showed that HBV DNA level was an independent risk factor for HBV reactivation (hazard ratio =1.000, 95% confidence interval: 1.000-1.000, P=0.015). The 1-, 3-, and 5-year survival rates were 56.20%, 30.30%, and 13.20%, respectively, in the ETV treatment group and 60.60%, 27.20%, and 16.30%, respectively, in the control group. There was no significant difference in overall survival rate between the two groups (χ2=0.049,P=0.755). ConclusionAntiviral therapy can reduce the incidence rate of HBV reactivation after TACE in patients with HBV-related HCC.

Objective: To observe changes in the molecular expression of the NLR Family Pyrin Domain Containing Protein 3 (NLRP3) pathway in depressed rats after treatment with Xiaoyaosan, and identify the regu-latory mechanism of this compound. Methods: Male Sprague-Dawley rats were randomly divided into five groups with 12 rats in each group, including the control group, model group, Fluoxetine group, Xiaoyaosan group, and MCC950 group. A depression model was generated by chronic immobilization stress (induced by 3 h of restraint immo-bilization every day), and the drugs were administered at the same time in each group for 21 days. The effects of Xiaoyaosan on behavioral changes of depressed rats were observed through macroscopic characterization, body mass, open field experiments, and a sucrose preference test. The mRNA and protein expression of the NLRP3 signaling pathway was examined by fluorescence real-time quantitative PCR and Western blot assays. Results: The Xiaoyaosan group, Fluoxetine group, and MCC950 group rats showed improved depressive behavior and an increased weight of sucrose water consumption. The protein and mRNA expression levels of NLRP3, Caspase-1, and IL-1β were also decreased in the Fluoxetine, Xiaoyaosan, and MCC950 groups. Conclusion: NLRP3, Caspase-1, and IL-1β protein and mRNA expression levels were increased in the cortex of depressed rats, while Xiaoyaosan protected cortical tissue in these rats by decreasing NLRP3, Caspase-1, and IL-1βprotein and mRNA expression.

The elimination of hepatitis C virus(HCV) infection is still a long way to go.Directacting antiviral agents (DAAs) can make HCV completely cured by targeting various stages of its replication life cycle and meanwhile standardize and simplify the treatment.However,those relative factors may affect efficacy and safety should be considered by specialties in choosing the suitable regimens.Therefore,this article reviews various aspects of DAAs including development history,factors correlated with efficacy and safety,therapeutic regimens domestic listed and approved.

Depression and anxiety is one of common mental illness that are being seriously harm to the physical and mental health of human being in recent years.Depression and anxiety are difficult to be well treated with a single and targeted drug,owing to its biological-psychological-social interaction pathogenic feature.Due to its own multicomponent characteristics,traditional Chinese medicine (TCM) compound Xiao-Yao (XY) powder can exert the antidepression and anxiety effects from multi-level,multi-link and multi-target.Based on previous studies on effect and mechanism of XY powder on anti-depression and anxiety of our group,we proposed that XY powder had two main characteristics when treating depression and anxiety,which were "two-way adjustment" and "multi-target,multisystem,multi-level".Additionally,to further clarify the pharmacodynamic material basis of XY powder,more importance is that we should depend on the variety of disciplinary research methods,focused on the TCM syndrome and the combination of disease and TCM syndrome,brought both disease evaluation and syndrome evaluation method,took the importance of gut-brain axis (GBA),and combined with the correlation between the formula and the syndrome.

Liver is no longer the only organ in the concept of anatomy,but it is a concept that has some specific functions in the visceral manifestations of liver.Liver is wood in the five element theory.It is yang of yin.Liver qi connects to the spring qi.Therefore,the liver function is to dredge and smooth qi of the whole body,which influences the blood and body fluid operation,the operation of the spleen and stomach,emotional changes and reproductive function and many other aspects.Suwen said "liver stores blood",which means that liver has the function of storing,regulating and controlling blood."Liver corresponds to the spring",which means changes in four seasons can affect the function of organs,but also contain the disease occurrence with a seasonal concept,which is an important part of visceral manifestation of liver.Modern medical research achieved some results from the nerve-endocrine-immune network,traditional four-axis,liver-blood vessels as the starting point for the liver as the theoretical mechanism of in-depth study.It was found that depression due to liver failed in soothing was related to the central cortex,the marginal system and the hypothalamicpituitary-adrenal (HPA) axis.The study covered neuropeptide and neurotrophic factor,monoamine neurotransmitter,central amino acid level,and etc.Liver stores blood,which is related to human coagulation system,EPO pathway and hemorheology.Liver corresponds to the spring,which is related to the neuroendocrine-immune network.And the pineal gland may be the highest regulatory site.At present stage,the study was conducted on the microcosmic mechanism of liver visceral manifestations from the gene and protein level.It was used to verify the regulation of liver function abnormality caused by the regulation of liver function in order to greatly explore the biological basis of traditional Chinese medicine (TCM) theory.

Three factors were extracted by exploratory factor analysis and could explain 55.75% of the total variance. Conclusions The Chinese version of DSAS-2 has acceptable reliability and validity,which can be used to evaluate stigma among patients with type 2 diabetes in China.

BACKGROUND:Electroacupuncture has promoting effects on the functional recovery of the injured spinal cord, can decrease pain, and elevate postoperative effect after acute spinal cord contusion.OBJECTIVE:To observe the effect of electroacupuncture on apoptosis in the injured site after spinal cord contusion, and analyze its neuroprotective effects on neurological function in rats with spinal cord contusion. METHODS:A total of 66 adult female Sprague-Dawley rats were randomly divided into: sham surgery group (n=20), spinal cord contusion group (n=20), electroacupuncture stimulation group (n=20) because six rats were excluded due to modeling failure and death. Before model establishment, at 1, 3 days, 1, 2, 3 and 4 weeks after model establishment, motor functions were evaluated by BBB score and the inclined plate test. At 3 days after model establishment, apoptosis of nerve cels could be detected in the site of injury in each experimental group using TUNEL assay. mRNA and protein expression of bax, bcl-2 and caspase-3 was detected surrounding the injury site using RT-PCR and western blot assay. Morphological changes in the site of injury could be observed using hematoxylin-eosin staining. The regeneration of nerve fibers was observed using HRP tracing. RESULTS AND CONCLUSION:(1) Motor function score was significantly increased at various time points in the 2nd week of treatment in the electroacupuncture stimulation group than in the spinal cord contusion group (P< 0.05). (2) Apoptotic index was significantly lower in the electroacupuncture stimulation group than in the spinal cord contusion group at 3 days after model establishment (P < 0.05). (3) mRNA and protein expression of bax and caspase-3 was significantly lower in the electroacupuncture stimulation group than in the spinal cord contusion group at 72 hours (P < 0.05); bcl-2 gene and protein expression was significantly higher (P < 0.05). (4) The number of HRP-positive nerve fibers was highest in the sham surgery group, folowed by electroacupuncture stimulation group, and lowest in the spinal cord contusion group at 4 weeks (P < 0.05). Results indicated that electroacupuncture plays a protective role on the spinal cord contusion by reducing apoptosis of nerve cels at the site of injury.
