A questionnaire survey was conducted among 319 mental health workers from 319 grassroots health institutions of 21 districts (cities,counties) in Chengdu in March 2013.The items of survey included general information of participants,subjective perceptions and status of community mental health services.Total 252 effective questionnaires were received,the average age of participants was (33.12 ± 9.39) years (19-61);59.5％ had clinical medicine and 16.3％ had public health background;most of them had educational levels of three-year college or below (84.9％);the average duration of working experience was 18 months;86.5％ was part-time;most of participants (87.4％) thought that the mental health service was a hard job and only 25.3％ expressed satisfaction with the work.Only 16.3％ of community health service centers had rehabilitation facilities for mental illness patients.Public health education was carried out for average (2.21 ± 1.62) times/year,the education for mental patients and family members was (1.62 ± 1.83) times/year.Between areas with sufficient detection rate of mental illness and those with insufficient detection rate,there was significant difference in training frequency of mental workers (P =0.012),there were no significant differences in having formal employment of mental workers (P =0.064),professional guidance,co-working with police officers,co-working with Disabled Persons' Federation,and the duration of working experience (all P ＞ 0.05).The results suggest that the capacity of mental health service in community levels is relatively weak in Chengdu,and the personnel training,public education and rehabilitation work of mental health need to be strengthened.

Objective: To explore the protective effect of salvia miltiorrhiza for enteral nutrition in S-MODS model rats.Methods: 70 Wistar rats were randomly divided into four groups: control group (n=10), model group (n=20), nutrition fibre group (n=20) and salvia miltiorrhiza for enteral nutrition group (n=20) . The experiment period was 12 days. At the end of experiment, blood routine, biochemistry index (ALB, AST, ALT, BUN, Cr, CK and CK-MB), the concentrations of IL-6,TNF-α and IL-1β were measured. Results: The model was successful by clinical manifestation,blood routine and pathology. The clinical symptom was improved, blood routine and pathology damage were relieved in salvia miltiorrhiza group. The concentrations of IL-6, TNF-α and IL -1 in salvia miltiorrhiza group were lower than model group and nutrition fibre group(P<0.05).Conclusions: Salvia miltiorrhiza for enteral nutrition could prevent gut function damage,protect intestinal mucosa and decrease the concentrations of pro-inflammatory cytokines.

Objective To investigate the job stressors and burnout of senior nurses, and explore the possible strategies for alleviating stress and reduction of demission rate of senior nurses. Methods Two hundred and thirty head nurses and senior nurses were included in this study. Nurse Job Stressors Inventory (NJSI) and Maslach Burnout Inventory (MBI) were applied to evaluate the burnout and work-related stress of nurses with the combination of convenience sampling and cluster sampling. Results The NJSI scores of senior nurses and head nurses were (2.62 ± 0.56) points, (2.45 ± 0.47) points, the two scores were significantly different (t=-2.465,P<0.05); the scores of three dimensions of MBI in senior nurses were (30.01±11.86) points, (8.01±5.74) points, (35.35±9.57) points, while the scores in head nurses were (21.65±10.39) points, (5.14±3.37) points, (38.81±8.45) points. Statistically significant difference was seen between the two groups (t=-5.261,-4.705, 2.691,P<0.05). There was a higher positive correlation between job stressors and burnout of senior nurses (r=0.521) than head nurses (r=0.432). Conclusions The level of job burnout is higher in senior nurses than head nurses, attributing to the higher controllability of head nurses. It is suggested to reduce the job burnout of senior nurses and to keep senior nurses in the profession fields, based on the theory of magnetic hospital.

Objective:To analyze the risk factors of neovascular glaucoma (NVG) after 25G pars plana vitrectomy (PPV) in proliferative diabetic retinopathy (PDR).Methods:A retrospective study. From January 2017 to December 2018, 340 PDR patients (340 eyes) with vitreous hemorrhage (VH) who were first treated with PPV in Tianjin Medical University Eye Hospital were included in the study. Among them, 185 were male and 155 were female, with an average age of 55.79±10.82 years. The duration of diabetes was 13.01±7.70 years, the fasting blood glucose was 7.55±2.15 mmol/L. Nineteen patients combined coronary heart disease, and 20 patients combined cerebral infarction. All patients underwent best-corrected visual acuity (BCVA), intraocular pressure (IOP), non-contact fundus examination, and fundus color photographs. BCVA was measured using an international standard Snellen visual acuity chart, and the values were converted to logarithm of the minimum angle of resolution (logMAR) scores for data analysis. The baseline logMAR BCVA was 2.04±0.73, The baseline IOP was 15.45±2.93 mmHg (1 mmHg=0.133 kPa). The duration of VH was 2.98±1.46 months, ranged from 3 weeks to 6 months. Three hundred and forty eyes included 93 eyes of PDR Ⅳ stage (27.35%), 107 eyes of Ⅴ stage (31.47%), and 116 eyes of Ⅵ stage (34.12%), combined tractional retinal detachment (TRD) 83 eyes. All patients underwent 25G standard three channel vitrectomy through the pars plana of the ciliary body. Preoperative anti-VEGF injection was performed in 57 eyes, internal limiting membrane (ILM) peeling in 234 eyes, combined phacoemulsification cataract surgery in 262 eyes and 141 eyes intravitreal anti-VEGF injection at the end of surgery. The patients were followed up for at least 12 months, with an average follow-up time of 10.80±5.79 months. NVG was defined as the presence of neovascularization in the anterior chamber angle or iris with an IOP higher than 21 mmHg after vitrectomy. Kaplan-Meier method and Cox univariate and multivariate regression were used to analyze the relationship between baseline factors, ocular factors, surgical factors and the occurrence of NVG after surgery.Results:Among 340 eyes, 66 eyes (19.41%) developed NVG after vitrectomy during 12 months of observation, NVG occurred from 6 to 335 days after surgery, and the mean period between vitrectomy and developing NVG was 98.00±5.79 days. The incidence of NVG was 11.50%, 15.29% and 20.75%, respectively in the 3rd, 6th and 12th month after PPV. The result of univariate analysis with the Cox regression analysis showed that the development of NVG at 12 months after surgery and age, combined coronary heart disease or cerebral infarction, combined with cataract phacoemulsification, ILM peeling, preoperative anti-VEGF injection had effect on postoperative NVG ( P<0.05). Ocular factors such as PDR staging, combined TRD, preoperative logMAR BCVA, preoperative intraocular pressure, etc. had no effect on the occurrence of NVG after surgery ( P>0.05). Combined cataract phacoemulsification surgery, internal limiting membrane peeling, surgical factors such as intracavity injection of anti-VEGF drugs 3 days before surgery, had an impact on the occurrence of NVG after surgery ( P<0.05). The meaningful variables of the Cox univariate analysis were incorporated into the multivariate Cox proportional hazard model for analysis, and the influencing factors of NVG after surgery were gradually regressed. The results showed that age, coronary heart disease or cerebral infarction, combined with phacoemulsification of cataract, and internal limiting membrane removal during surgery were independent risk predictors of NVG after surgery ( P<0.05). Conclusions:Younger, coronary heart disease or cerebral infarction, combined with cataract phacoemulsification are the risk factors of NVG in PDR patients after PPV. The removal of internal limiting membrane can reduce the incidence of NVG.

ObjectiveTo determine the feasibility of using left ventricular volume-time curve in the evaluation of left ventricular diastolic function,and to analyze characteristics of left ventricular volume-time curve changcs in hypertrophic cardiomyopathy (HCM).MethodsSeventeen cases of HCM and 12 healthy volunteers received cardiac MRI (CMRI) examination,and left ventricular (LV) 2-chamber long and short axis cine imaging were performed,LV volume-time curves were reconstructed and platform time,different diastolic volume recovery (DVR) time and their corresponding filling velocity were calculated from LV volume-time curve off-line.The DVR time and their corresponding filling velocity were analyzed by using multiple linear regression analysis. Results Compared with the group of healthy volunteers,ventricular septal HCM group had delayed left ventricular 50％,70％ DVR time[ (8.9 ± 1.3) versus (7.7 ± 0.8 ) phase,F=6.787,P=0.016;(11.3 ±1.6) versus(9.7±1.8) phase,F=4.927,P=0.036] and shortened plateau time [ ( 1.8 ± 1.7) versus ( 4.1 ± 1.4 ) phase,t =6.787,P ＜ 0.01 ].Ventricular septal HCM group had reduced 30％,50％ DVR filling rates [ (0.22 ± 0.11 ) versus (0.40 ± 0.15 ) ml/ms,F =12.916,P ＜ 0.01 ; (0.20 ± 0.09 ) versus (0.30 ± 0.10) ml/ms,F =7.121,P =0.014 ] compared with those in the group of healthy volunteers.But 70％,80％,90％ DVR filling rates showed no statistically significant different in the two groups.In HCM patients,myocardial fibrosis caused 50％,70％,80％ DVR time delay [ (9.6 ± 1.0) versus ( 7.9 ± 1.5 ) phase,F =5.000,P =0.045 ; ( 12.3 ± 1.4 ) versus ( 9.6 ± 1.8)phase,F=8.039,P=0.015;(13.1 ±1.4 ) versus(10.9±1.9)phase,F=5.060,P=0.044],but no significant difference of DVR filling rate was found between the two groups. Conclusions Left ventricular volume curve analysis techniques can be used for detailed evaluation of left ventricular diastolic function.The left ventricular diastolic dysfunction of hypertrophic cardiomyopathy occurs mainly in early diastolic period,and accompanied by the shortening of the plateau time. Myocardial fibrosis can aggravate early left ventricular diastolic dysfunction of hypertrophic cardiomyopathy.

Objective To explore the inhibitory effects of Corilagin on the production of proinflammatory cytokines in microglia induced by radiation. Methods The cytotoxicity of Corilagin was measured by MTT assay. Microglia BV-2 cells were irradiated 0 or 32 Gy after pretreated with Corilagin for 12 hours. Realtime-PCR was used to detect the mRNA levels of inflammatory cytokines, such as IL-1β,TNF-α on several time-points. The content of nitric oxide (NO) was determined with nitrate reductase method. The translocation of NF-κB was measured by Western blot and immunocytochemical stain.Confocal microscopy was used to observe the expression of Iba-1 and Nemo. Results No cytotoxicity was detected on BV-2 cells with 1-10 μg/ml Corilagin. Iba-1 expression in microglia cells was activated by irradiation, the expression levels of inflammatory cytokines, such as IL-1β, TNF-α and NO were also elevated. Whereas, the production of IL-1 β, TNF-α in activated microglia cells was significantly inhibited with 5 μg/mL corilagin ( tIL-1β = 6. 341, tTNF-α = 3.41 1, tNO = 3. 134, P ＜ 0. 05 ). Corilagin significantly inhibited the expression of Nemo and the translocation of NF-κB p65. Conclusion Corilagin could inhibit the activation of irradiated microglia cells and down-regulate the expression of inflammatory cytokines, via inhibition of the NF-κB signaling pathway.

Objective:To investigate the relationship between cancer-related fatigue and cortisol in cancer patients and elucidate the underlying mechanism. Methods:A total of 80 cancer cases were divided into two groups:fatigue group (50 cases with cancer-related fatigue) and non-fatigue group (30 cases without fatigue). The scores were evaluated through the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and the Fatigue Symptom Inventory (FSI) report. Serum specimens were examined through electrochemiluminesence immunoassay and enzyme-linked immunosorbent assay. Serum cholesterol was examined through the CHOD-PAP method, and serum total protein and albumin were determined via the Biuret method. Agarose gel electrophoresis was conducted to determine alpha 2 globulin ratio and to calculate serum alpha 2 globulin concentration. Results: The cortisol level in the fatigue group was significantly lower than that in the non-fatigue group[(119.68±5.34) nmol/L vs. (163.45± 31.49) nmol/L, P<0.05], and the adrenocorticotropic hormone (ACTH) level in the fatigue group was significantly higher than that in the non-fatigue group [(104.50 ± 17.15) ng/L vs. (51.43±13.24) ng/L, P<0.05]. Cortisol negatively correlated with MFSI-SF (r=-0.867, P<0.001) but positively correlated with ACTH (r=0.809, P<0.001). Furthermore, cortisol negatively correlated with FSI (r=-0.747, P<0.001) but positively correlated with ACTH (r=0.70, P<0.001). The levels of serum cholesterol [(1.25±0.70) mmol/L vs. (3.28±0.73) mmol/L, P<0.05], albumin[(18.24 ± 7.03) g/L vs. (37.40 ± 8.05) g/L, P<0.05], and alpha-2 globulin [(2.25±1.07) g/L vs. (5.36±1.09) g/L, P<0.05]were significantly lower in the fatigue group than in the non-fatigue group. Conclusion:The patients with cancer-related fatigue exhibited increased MFSI-SF score, decreased serum cortisol level, and enhanced ACTH level. The low serum cortisol levels caused a disorder in the serum ACTH and cancer-related fatigue of malignant tumor patients. The mechanism underlying the reduction in serum cortisol level correlated with the insufficient amounts of serum cholesterol, the composite material of cortisols, and of serum albumin, particularly alpha-2 globulin, the carrier protein of serum cholesterol.
