Objective To study the standardization of medical records writing by residents in hospitals. Methods With both quantitative and qualitative analysis, medical records made by residents were sampled in groups to study their standardization. Results Recognition rate of such medical records was 82. 55%, and the excellence rate was 24. 50% in the grade evaluation. For senior residents, their rate of writing excellence falls below those of junior ones; whether the evaluators have medical background bears no significant difference for grade evaluation of medical records writing, yet a significant difference was found with the recognition rate. Conclusion Writing of medical records by residents is found with incompliance now and then, and the recognition rate ought to be improved.

Objective To determine the effects of tacrolimus (FK506) pretreatment on the liver ischemia reperfusion (IR) injury.Methods 32 mature SD rats were randomly assigned into four groups,which were sham-operated group (S),ischemia reperfusion group (IR),low-dose FK506-treated group (L) and high-dose FK506-treated group (H).After the treatment of liver ischemia for 60 minutes and reperfusion for 6 hours,the levels of serum ALT and AST in rats were tested.The TNF-α and IL-1β levels were evaluated by enzyme linked immunosorbent assay.Liver damage was assessed by paraffin sections stained with H&E.The quantitative real-time PCR,the immunohistochemistry and Western blot were used to detect the expression of HMGB1 mRNA and protein with or without FK506 pretreatment.Results The levels of serum ALT [(424.0 ± 137.4)U/L,(291.0 ±42.0)U/L],AST [(554.2 ± 127.7)U/L,(410.2 ±7.0)U/L],TNF-α [(115.1±49.0)ng/L,120.4±28.5) ng/L] and IL-1β [(424.5 ±105.2) ng/L,(612.1 ± 49.6) rig/L] decreased markedly in the group L and group H compared with the group IR (P ＜ 0.05).The liver in the IR group showed hepatic sinusoids congestion,neutrophil infiltration and necrosis.In contrast,tissue damage of the L group and the H group was significantly decreased.The expressions of HMGB1 mRNA and protein reduced significantly when pretreatment with FK506 after reperfusion (P ＜ 0.01).However,there was no significant difference between the group L and group H (P ＞ 0.05).Conclusion FK506 pretreatment can protect the liver by reducing the expression of HMGB1,inhibiting the release of inflammatory cytokines and alleviating cell necrosis after the liver ischemia reperfusion injury in rats.

Full-speed development of the primary health care centering on community health service is key to the ongoing health reform in China. Building a new management mechanism for these grass-root health centers is an innovative approach of such a reform as carried out in Zhejiang province.The authors described the present management mechanism in the province, and focused on the specific measures and main outcomes of the nine Group-scale model as used by a district health bureau in Hanzhou since end of 2007. The paper aims at building an ideal model for group-scale management of community health centers, and improving the new city primary health care system centering on community health service.

Objective To investigate the correlation of spiral CT features with expression of E-cadherin(E-cad) in peripheral lung cancer.Methods Spiral CT scans were performed in 58 patients with peripheral lung cancer confirmed by pathology.Expression of E-cad in 58 cases were detected with SP immunohistochemical techniques.Spiral CT findings were compared with expression of E-cad.Results The abnormal expression of E-cad was showed in 32 cases(55.17%).The positive rates of E-cad expression were 40.63% in I-II cell differentiation group and 73.08% in III-IV cell differentiation group,and the difference was significant(P＜0.05).The abnormal expression of E-cad was associated with the CT features,such as lymph node metastasis,pleural invasion and the size of tumor(P＜0.05),but not the cavity sign,spicular sign and vessel convergence sign(P＞0.05).Conclusion E-cad gene over expression may play an important role in the pathogenesis and CT appearances of lung cancer.

Objective Although heart transplantation surgery has become more common,little is known about the psychological status of patients waiting for a heart transplant.Method Ninety-three patients registered for heart transplantation from March 2013 to March 2014 in a large general hospital in Shanghai were assessed by a psychiatrist using the Hamilton Depression Scale (17 items) and the Hamilton Anxiety Scale.Out of them 36 were preoperatively admitted to the Cardiac Surgery Department.The scales were assessed repeatedly at the 1st day,3rd day,7th day,10th day and so on until the operation took place.Result The mean scores of HAMD and HAMA of 93 patients in the waiting list were separately 13.11 ±3.81 and 14.20±4.57.Among them 18(19.4％) were classified as moderately depressed,31(33.3％) had moderately anxious symptoms,and 14(14.1％) had severe anxious symptoms.Thirty-six patients were preoperatively admitted to hospital.Their mean scores of HAMD and HAMA were separately 13.19-± 3.82 and 16.17 ± 4.35.Among them 7(19.4％) were classified as moderate depression at the time of admission,16 (44.4％) had moderately anxious symptoms and 9 (25.0％) had severe anxious symptoms.The scores of HAMD had significant difference (t =3.383,P =0.002) before and after admission.Paired t test was separately conducted to analyze the first assessment and the 3rd-day assessment of HAMA and HAMD total scores after admission of all the inpatients.The results showed the scores were statistically different (for HAMA,t =2.786,P =0.009; for HAMD,t =14.024,P =0.000).Repeated ANOVA was used to analyze the recipients who had three assessments.The results had statistical difference (for HAMA,F =4.568,P=0.020; for HAMD,F=5.626,P =0.034) and the difference of HAMD score at different time points had a linear trend (F =8.273,P =0.013).Conclusion After hospital admission,the depression symptoms will be significantly alleviated.When waiting for the transplant in the hospital,the anxiety symptoms alleviate slightly in three days and then aggravate significantly.The depression symptoms alleviate slightly continuously.

Objective:To explore the expression of B7-1,B7-2 and B7-H1 on tumor-infiltrating dendritic cells(TIDC) and on splenic dendritic cells(SDC),and to investigate TIDC-mediated and SDC-mediated T-cell function after blocking B7-H1 expression in these dendritic cells.Methods: The TIDCs and SDCs were isolated from tumor-bearing mice using anti-mouse CD11c magnetic beads.The expression of B7-1,B7-2 and B7-H1 on TIDC and SDC was analyzed using flow cytometer.T cells were co-cultured with TIDCs or SDCs for the mixed lymphocyte reaction(MLR),and monoclonal antibodies to B7-H1 or the isotype control antibodies were added to the MLR cultures.T-cell proliferation was assessed using XTT method and the secretion of IL-10 was detected using ELISA.Results: B7-1 and B7-2 positive TIDCs were significantly less than SDCs(P0.05).T-cell proliferation stimulated by TIDCs was weaker than that stimulated by SDCs;T cells produced more IL-10 after TIDCs stimulation than after SDCs stimulation(P
