Objective To analysis the basic condition of the health resources in Chongqing ,and to explore the effect of the al‐location of health resources on doctor‐patient relationship .Methods Health statistics yearbook of Chongqing city was collected ,the fairness of the allocation of health resources in chongqing carried on the analysis and evaluation ,using the DEA model to analyze and evaluation the efficiency of the allocation of health resources in chongqing ,self‐designed questionnaire was used;hospitals ,doc‐tors and patients were investigated ,the descriptive and statistical analysis carried on .Results The distribution of health resources in Chongqing was inequitable on a regional .This inequitable distribution had been evaluated to the effect that ,as per the DEA mod‐el ,7 prefectures were effective with another 5 slightly effective and 26 as DEA ineffective .In the 8 hospitals that had been investiga‐ted ,the occurrence of medical disputes was undergoing a surge ,which indicates the tense relation between doctors and patients .Con‐clusion The total amount of health resources in Chongqing is fairly insufficient ,the high quality health resources are scarce .Unbal‐anced allocation of health resources and allocation inefficiency is the main reason for nervous doctor‐patient relationship and contra‐diction focus .

Objective To study the effects of high matrix metalloproteinase 9 (MMP 9 ) on the biological behaviors of fibroblasts,in order to clarify the possible mechanisms in the wound healing of diabetic foot.Methods Establish the cell model of skin fibroblast with high expression of MMP 9 by high glucose (22.0 mmol/L) and high homocysteine (100 μmol/L) co-culture.Control group was incubated with normal glucose (5.5 mmol/L).Realtime PCR,ELISA and gelatin zymography were used to detect the MMP 9 mRNA,protein expression and activity of MMP 9.Flow cytometry,CCK-8,ELISA assay,scratch test and transwell were used to detect cell proliferation,viability,collagen (hydroxyproline) secretion,horizontal migration and vertical migration of cells.Results Data were expressed as (x- ± s).Differences were considered significant if their P value was ＜ 0.05.Results The expression of MMP 9 mRNA,protein levels and the activity of MMP 9 in high MMP 9 group were 6.05 folds,4.12 folds and 1.58 folds higher than those in control group (P ＜ 0.01,respectively).The proportion of S phase cells,proliferation index,cell viability,collagen (hydroxyproline) secretion,6 h horizontal migration rate and the number of vertical migration cells in high MMP9 group decreased by 29.8 ％,18.1％,23.3 ％,68.7 ％,45.0 ％ and 21.4 ％ than those in control group (P ＜ 0.01,respectively ). Conclusions Fibroblast with high expression of MMP 9 have decreased proliferation,activity,collagen secretion and reduced migration,which suggests that MMP 9 may inhibit the biological behaviors of fibroblasts.

A 36-year-old woman presented with a 3-year history of pruritic erythema and scaling on the trunk and extremities.Dermatological examination revealed ill-defined light pink macules with white lamellar scales on the chest,abdomen and buttocks.Histologically,there was a focal mononuclear cell infiltrate in the superficial dermis,with the epidermotropism of some cells and mild atypia of epidermotropic cells,as well as an interstitial mononuclear cell infiltrate and mild deposition of mucin between the collagen fibers in the middle dermis.CD3 and CD4 were expressed by scattered mononuclear cells infiltrating the upper and middle dermis.Based on these data,the patient was diagnosed with interstitial granuloma fungoides.

The care and support for the patient of AIDS is a vital content,we should enhance international collaboration and intercourse of information,which can promote efficiency.This text shows an analysis on the actuality and characteristic of the support mode of the AIDS community in British.Its purpose is to summarize the successful experience for china and improve the support mode for AIDS.

Objective: To optimize andrographolide pellet by using a quality by design (QbD) approach. Methods: Usingthe cumulative in vitro release as evaluation index, the single-factor investigation and hazard analysis were used to study the core and coating process of andrographolide colon-targeting pellets, and the central composite design-response surface method was used to optimize and predict the three key factors of plasticizer dosage, aging time, and coating weight gain. Results: The optimum coating process parameters were as following: plasticizer dosage of 3 g, coating weight gain of 20%, and aging time of 1 h. The process had been verified that the optimal formulation process had a cumulative in vitro release of 6.9% in the acid phase (0.1 mol/L HCl)-buffered salt phase (pH 6.0) and a cumulative in vitro release of more than 90% in the pH 7.2 buffered salt phase. Conclusion: It is feasible to apply the QbD concept optimization in the study of andrographolide colon-targeting pellets.

ObjectiveTo investigate the clinical characteristics,epidemiology of patients with severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) infection and genetic sequences of SFTSV.MethodsClinical data of five cases of severe fever with thrombocytopenia syndrome (SFTS)from Zhoushan Hospital during May 2011 to July 2011 were retrospectively analyzed.SFTSV gene was amplified by polymerase chain reaction (PCR).CD3+ CD4+ and CD3+ CD8+T lymphocytes were detected by flow cytometry (FCM).The sequences of isolated SFTSV strains were compared with those in GenBank. ResultsThe symptoms of continuous high fever,sore muscles,enlarged superficial lymph nodes,abdominal pain,diarrhea with gastrointestinal hemorrhage were observed.The white blood cells,platelets and CD3+ CD4+ T lymphocytes were progressive decreased in acute phase with the minimum of (0.97-2.00) × 109/L,(12-42) × 109/L and 7.52％-20.39％,respectively.The SFTSV was isolated from the sera of two patients.The sequences were compared with SFTSV sequences in GenBank.The homology of RNA-dependent RNA polymerase gene was 96％ compared with BX-2010,L-WWG,LN3,JS4,SD4,HN6 and AH12; the glycoprotein gene was 94％ ; N protein gene was 95％ compared with JS4,SD4 and LN4.The homology of the above three genes between two isolates was 99％.ConclusionsOur results suggest that SFTSV is sporadic in Zhejiang Province which is probably from native epidemic focus.SFTS is progressive and severe with acute onset.Multiple organ dysfunction is common in severe eases.
