Objective To analyze the family burden of the caregivers of the psychosis patients in community, and the psychosocial factors which influence the family burden.Methods Conducted some questionnaires to survey the requirement and attitude on mental health knowledge,social support,family burden and coping style of the caregivers of the psychosis patients from the twelve communities which served as the stations for the psychosis of the twelve prefectures organized uniformly by Guangdong provincial disabled federation.Results 360 questionnaire was provided,and 308 replied to our questionnaire effectively.The mean score of each single item of the family burden questionnaire was beyond the moderate.The factor score of the economy burden was the highest among the factots of the economy burden(2.33±0.52),the daily activity of the family(2.17±0.53),the recreation activity of the family(2.00±0.58),the family relationship(2.10±0.54),the body health of the family members (2.03±0.65),and the mental health of the family members(2.09±0.68).The bad emotion and experience with the patients aggravated some factors of the family burden(P<0.05～0.01).According to correlation analysis and regression analysis,there were significant relation and impact between family burden with the requirement and attitude on mental health knowledge,subject support,coping style,age,economy,culture and so on(P<0.05～0.01). Conclusion Negative assumption to mental health will aggravate the family burden,transfering the positive message and changing passive coping style will help to reduce the family burden.

Objective To investigate the requirement and the attitude of the mental health knowledge and some psychological factors indifferent developed regions. Methods The mental patients, their caregivers and normal people in total of 534 were surveyed with the Zung'sSelf-rating Depression Scale, the Questionnaire of Experience and Attitude of the Psychosis (self-edited), the Questionnaire of Requirementand Attitude on Mental Health Knowledge (self-edited), the Social Support Rating Scale and the Simplified Coping Style Questionnaire.

Objective To explore the efficacy and safety of double dosage of SHUGANJIEYU capsule on mod?erate depression. Methods The study was conducted by a multicenter, random, double-blind and parallel-controlled trial. Trial group received SHUGANJIEYU capsules 4# twice a day. Control group got two SHUGANJIEYU capsules and two simulated ones twice a day. The study lasted 56 days (8 weeks) for both groups. Primary efficacies were evalu? ated by the total score and score changed rate of Hamilton depression scale-17 (HAMD-17)and Hamilton anxiety scale (HAMA) as well safety by reported adverse events and laboratory tests for patients. Results One hundred twenty patients were recruited in trial group and 120 patients in control group. After a 8-week treatment, the remission ratio was 84.2% and 63.3% for the trial group and the control group, respectively according to the HAMD-17. The differ?ence in the remission ratio was significant (P<0.05). Furthermore, the reduction rate of the total scores of HAMD-17 was 35.4% and 27.1% for the trial group and the control group at the 14th day of treatment, respectively, whereas 79.0%and 65.9%for the trial group and the control group at the 56th day. The reduction ratio was significantly higher in trial group than control group (P<0.01). The median time to response was 14 days in both groups. Based on the HA?MA, the remission ratio was 93.3%and 77.5%for the trial group and the control group respectively after 8 weeks and the difference in the remission ratio was significant between the two groups (P<0.05). Incidences of adverse effect were not significantly different between the two groups (17.5%vs. 11.7%, P>0.05). Conclusion SHUGANJIEYU capsule ex?hibits a good therapeutic effect on the depressive symptoms and anxiety symptoms in patients with moderate depres?sion. Double doses of SHUGANJIEYU capsule can increase the effect of SHUGANJIEYU and accelerates SHUGAN?JIEYU-induced improvement of depression symptoms with an acceptable safety.

Neurodegenerative disease is a kind of degenerative diseases of the central nervous system that seriously endanger human health. The complement 3 (C3)-complement 3a receptor (C3aR) pathway is one of the important pathways for classical complement cascade activation. A large number of studies have shown that the C3-C3aR pathway can mediate and regulate the interaction of astrocyte-microglia axis in neurons, resulting in function changes in central nervous system. In addition, studies in recent years have found that the C3-C3aR pathway is closely related to the occurrence and progress of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, stroke, and epilepsy. This article reviews the progress of C3-C3aR pathway and discuss the role of C3-C3aR pathway in several important neurodegenerative diseases, and it provides a new idea fo treatment of these diseases.

ObjectiveTo understand the use of antibiotics in inpatients and the incidence and trend of hospital infections， to explore the implementation effect of comprehensive management measures， and to provide reference for hospitals to use antibiotics reasonably. MethodsBased on the hospital infection monitoring and management system， a retrospective analysis and comparison were conducted on the use of antibiotics， submission of microbial test samples， and incidence of hospital infections among inpatients in a tertiary hospital from 2012 to 2021. ResultsFrom 2012 to 2021， the use of antibiotics showed a downward trend， from 50.82% in 2012 to 41.29% in 2021. At the same time， the use rate of restricted and special antibiotics had also decreased， and the use rate of restricted and special antibiotics in patients without hospital infection was significantly lower than that in patients with hospital infection， and the microbial testing rate was also on the rise. The annual incidence rate of hospital infection was 0.69%‒1.92%， and the annual case-time prevalence rate was 0.79%‒2.17%. The annual average rate of the above two in 10 years was 1.18% and 1.34%， respectively. The results of the exponential smoothing model also showed that the utilization rate of antibiotics was decreasing and the incidence of nosocomial infection was stable. ConclusionLarge general hospitals took comprehensive management measures to strengthen the management of rational use of antibiotics， which led to a decline in the use rate of antibacterial drugs for inpatients and an increase in the rate of microbial examination. At the same time， the overall incidence of hospital infection was relatively stable， suggesting that the comprehensive management measures of antibacterial drugs in hospitals had achieved certain results. The current measures need to be optimized in the future to continuously improve the management level of rational use of antibacterial drugs.
