Objective To explore the relationship between the neighborhood environment and the residents' suicidal risk and provide evidence for suicide prevention.Methods The study sample consisted of 392young suicides (aged 15-34 years) and 416 community living controls from the same areas of China (randomly selected from 16 rural counties in three provinces).Social factors in the village neighborhoods were measured by the WHO SUPRE-MISS scale of Community Stress and Problems.Psychological autopsy methods and multivariable Logistic regression were employed.Two informants were interviewed to collect the information of each subject.Results It was found that there was positive correlation between the community surrounding score and suicide.The community stress and problems was the main risk factor for suicide(Wald x2 =10.036,P＜0.05,OR=1.323).Family disputes,inconvenience transportation,lack of health care and job security,alcohol abuse,and superstition can increase the suicidal risks among rural young Chinese.It was still indicated that relative poverty,suffering from a mental illness(OR=32.346) were the risk factors; but good education,married and good health were the protective factors for suicide.Conclusion Further improving the social assistance system,solving the existing community stress and problems,building better community environment are needed to reduce the stress of community residents.Psychological screening and the community mental health intervention for high-risk groups should be strengthened to improve residents' response capacity to stress.Those measures can reduce the suicide rate of China rural community residents effectively.

Cerebralvasospasmisthemostcommonandmostdangerouscomplicationofsubarachnoid hemorrhage (SAH). If it can not be diagnosed and treated early, it w il result in delayed cerebral ischemia and delayed ischemic neurological deficits, and seriously affect the outcomes of patients. SAH can cause oxidative stress and inflammation, causing vasospasm, and leading to brain tissue damage. Numerous studies have show n that the concentrations and activities of numerous metabolites w il change in these pathological physiological processes. Identification of the changes of location, time and trend of these markers has important clinical significance for investigating the mechanism of cerebral vasospasm after SAH and seeking better therapeutic targets. This article review s the molecular markers of cerebral vasospasm after SAH.

MicroRNAs are small,single-stranded and non-coding RNAs.MicroRNAs modulates gene expression by binding themselves to complementary sites of target genes.It had been discovered that micmRNAs modulate sepsis in multiple levels.Through targeting Ca2+/calmodulin-dependent protein kinase Ⅱ,miR-152 and miR-148 impair innate response and antigen presentation,and also suppress proliferation of antigen specific CD4 + T cells; miR-29 family regulate cellular immunity through setting the threshold in thymic involution; MicroRNA-17-92 plays a causative role in B cell lineage; miR-146 and miR-155 down-regulate proinflammatory cytokines through suppressing components of pattern recognition receptors,while miR-132 through acetylcholinesterase degeneration.miR-124 degenerates mRNA of glucocorticoid receptorαand results in glucocorticoid resistant in treatment of sepsis.Immune regulation of microRNAs in sepsis is briefly described in this paper.

OBJECTIVE:To provide reference for the rational use of narcotic drugs. METHODS:The utilization of narcotic drugs for inpatients in our hospital during 2012-2014 were collected from HIS,and analyzed statistically in respects of consumption amount,consumption sum,DDDs,B/A,DDC and consumption amount of the different departments,and so on. RESULTS:The quantity and consumption amount of Morphine sulfate sustained-release tablets,Oxycodone hydrochloride sustained-release tablets and Codeine phosphate tablet ranked the first 3 places during 2012-2014. Morphine sulfate sustained-release tablets,Oxycodone hy-drochloride sustained-release tablets and Fentanyl transdermal patch(8.4 mg)steadily occupied the first 3 places in the list of con-sumption sum. In the list of DDDs,Fentanyl transdermal patch and Morphine sulfate sustained-release tablets took up the first 3 places;Morphine hydrochloride injection,Bucinnazine hydrochloride injection and Meperidine hydrochloride injection occupied the last 3 places. B/A value of Morphine sulfate sustained-release tablets and Fentanyl transdermal patch(8.4 mg) in 2012,Oxycodo-ne hydrochloride sustained-release tablets in 2014,Fentanyl transdermal patch(2.5 mg)in 2013 and 2014 were all equal to 1 and synchronized well. Others were all biased. DDC of narcotic drugs kept stable in 3 years,and DDC of Oxycodone hydrochloride sus-tained-release tablets took up the first place,followed by Fentanyl transdermal patch (8.4 mg). Narcotic drugs were consumed in 19 departments,but mainly in the department of oncology and general surgery. In the department of oncology,the consumption amount and sum of oral formulation were both significantly higher than other dosage forms,accounting for more than 88% and 52% respectively. CONCLUSIONS:The variety and dosage form of narcotic drugs could meet the clinical needs and its application is basically reasonable. Besides,the utilization of narcotic drugs in the department of oncology consistent with the basic principles of WHO three steps cancer analgesia treatments.

Objective To investigate the role and mechanism of signal transducer and activator of transcription 4 (STAT4) in homocysteine (Hcy)-induced proliferation,migration and senescence of human aorta smooth muscle cells (VSMCs).Methods After VSMCs were incubated with Hcy (0-0.50 mmol/L) for various time periods,a CCK-8 assay was performed to determine proliferation activity.Modified Boyden chamber system (Transwell apparatus) was used to examine migration ability.A SA-β-gal staining kit was used to determine senescence status.Western blotting was performed to examine the expressions of STAT4 and phosphorylated STAT4 (p-STAT4) proteins,and ELISA was performed to examine MCP-1 expression.Results Hcy (from 0.05 mmol/L) significantly increased the proliferation of VSMCs (P ＜ 0.05).Hcy (from 0.10 mmol/L) significantly increased the migration of VSMCs (P ＜ 0.05).Hcy promoted the senescence of VSMC in a concentration-dependent manner,and significantly increased VSMC senescence when the concentration of Hcy reached 0.10 mmol/L (P ＜ 0.05).Hcy (from 0.10 mmol/L) treatment significantly increased the expression of p-STAT4 (P ＜ 0.05) and MCP-1 (P ＜ 0.05).Conclusions Hcy increases the proliferation,migration and senescence of VSMCs,probably by the activation of STAT4 pathway.

Objective To evaluate the effects of aerobic combined strength and balance exercise on cognitive function and satisfaction in patients with cognitive impairment no dementia. Methods Four hundred and twenty patients with cognitive impairment no dementia were divided into control group (200 cases) and experimental group (220 cases) by random digits table method. The control group received general health education and rehabilitation training. The experimental group received aerobic combined strength and balance exercise. The patients were assessed with Montreal Cognitive Assessment (MoCA) to evaluate their cognition before training, as well as after training. And the patients′satisfaction with the questionnaire was evaluated. Results The total scores of MoCA, scores of name, attention, language, memory and directionafter training were (23.47 ±2.38), (2.77 ±0.42), (5.09 ±0.86), (2.50 ±0.65), (3.42 ±0.68), (5.03 ± 0.10) points in the experimental group, and (21.20±2.55), (2.31±0.76), (4.71±1.10), (2.35±0.70), (2.23±0.81), (4.48±0.96) points in the control group, and there were significant differences, P<0.05. There were no significant differences in the space and abstract thinking between experimental group and control group:(3.61±0.91) points vs. (3.45±1.09) points, (1.83±0.76 ) points vs. (1.72±0.52) points, P>0.05. The scores of satisfaction in the experimental group was significantly higher than that in the control group:(49.33 ±1.57) points vs. ( 48.20 ±2.14) points, P<0.01. Conclusion The application of aerobic combined strength and balance exercise could improve the cognitive function and patients′satisfaction.

Internal mammary nodes are part of the first stop of mammary gland lymphatic drainage.It plays an important role in the process of occurrence and development of breast cancer.Whether irradiation internal mammary nodes or not is still a larger controversy.At present,for the early stage patients,the efficacy of internal mammary lymph node irradiation is not clear.For the patients with positive axillary lymph nodes,inboard or central quadrant lesions,postoperative radiotherapy of internal mammary nodes has a certain value.

Objective To understand the nurses' evaluation of current grading nursing system.Methods Self-questionnaire was designed and used to investigate 141 clinical nurses coming from three general hospitals sampled conveniently.Results (1)Clinical nurses lacked in-depth study of grading nursing instruction principle;(2)Doctors and nurses lacked the cooperation during the process of identifying the level of care;(3)Level of care was not consistent with the patients' condition and self-care ability;(4)Disease inspection and primary care were not consistent with patients' level of care;(5)Health guidance and mental nursing couldn't meet the actual needs of patients;(6)Senior nurses' evaluation of the implementation of grading nursing was lower than Junior nurses; (7)Clinical nurses held positive attitudes to nurses and patients participating in grading nursing.Conclusions Nurses thought poorly of grading nursing system in operation,it was necessary to improve the content of principles about grading nursing manner,health instruction and psychological nursing,and implement grading nursing system correctly.It was also important to take patients' willingness of participating in care into account.
