1.Practice and exploration of the health reform in Wuhu city
Chinese Journal of Hospital Administration 2013;29(10):721-723
Wuhu City has been exploring,since 2007,an innovative health and medical system featuring both the reform of public hospitals and that of the primary care system.This reform aims at strengthening the public health service system,improving the basic medical service system,speeding up the construction of the medical security system,and improving the drug supply system.It is characteristic of a core,two wings,and four-wheel drive,which tells the essence of Wuhu' s reform practices and outcomes.

Objective To examine the levels of serum tissue inhibitor of metalloproteinase in severe sepsis patients with disseminated intra-vascular coagulation (DIC) and evaluate its diagnostic value in severe sepsis with DIC.Methods Sixty patients were divided into 3 groups,namely severe sepsis group (SS group,n =28),severe sepsis with DIC group (SSD group,n =12) and normal group (n =20).Clinical data including APACHE Ⅱ score and DIC score of these patients were collected.Serum levels of TIMP-1 and TIMP-2 of these patients were measured by using ELISA.Results The patients of SS group had higher levels of TIMP-1 (723.74 ± 96.27) and lower levels of TIMP-2 (68.08 ± 14.87) than healthy control subjects (TIMP-1:574.24 ± 79.99,TIMP-2:89.99 ± 18.45) (P < 0.05).The patients of SSD group had higher levels of TIMP-1 (907.56 ± 200.20) and lower levels of TIMP-2 (44.84 ± 22.13) than patients of SS group (P < 0.05).An association was found between TIMP-1 and fibrinogen (FIB) (r =-0.392,P < 0.05),TIMP-1 and D-dimer (r =0.407,P < 0.05),TIMP-2 and PLT (r =0.484,P <0.01),TIMP-2 and PCT (r=-0.523,P<0.01),TIMP-2 and DIC score (r=-0.579,P<0.01).The areas under the curves (AUC) for TIMP-1/TIMP-2 was 0.896 (95% CI:0.843 ~ 0.950 (P < 0.05).Conclusions Serum levels of TIMP-1 in patients with severe sepsis complicated with DIC increased and TIMP-2 decreased,suggesting they were valuable in diagnosis of severe sepsis complicated with DIC.

OBJECTI VE To optimize the extraction technology of the leaves of Dimocarpus longan according to flavonoids and phenolic acids. METHODS The contents of gallic acid ,protocatechuic acid ,ethyl gallate ,quercetin,luteolin and kaempferol in the leaves of D. longan were determined by HPLC. Based on single factor test ,with the ethanol volume fraction ,solid-liquid ratio and extraction time as factors ,using comprehensive scores of the contents of above six components as indexes ,the extraction technology of the leaves of D. longan was optimized by Box-Behnken response surface methodology. RESULTS The optimal extraction technology included ethanol volume fraction of 100%,solid-liquid ratio of l ∶ 7(g/mL),extraction time of 90 min, extraction temperature of 80 ℃. After 3 times of validation tests ,the average comprehensive score was 97.54(RSD=0.33%,n= 3),relative error of which with predicted score (99.05)was 1.55%. CONCLUSIONS Box-Behnken response surface methodology combined with multi-index comprehensive score can be used for the extraction technology of the leaves of D. longan ,and the optimized extraction technology is stable and feasible.

OBJECTIVE To study the metabolites derived from the ethanol extract from the leaves of Dimocarpus longan preliminarily in rats in vivo ,and to provide reference for elucidating the possible metabolic mechanism of the leaves of D. longan in lowering blood glucose . METHODS Ultra high performance liquid chromatography quadrupole time -of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) was adopted by taking ethanol extract of D. longan leaves,the feces and urine of rats at 0-72 h and 0-48 h after intragastric administration of 33.8 g/kg ethanol extract of D. longan leaves(by extract ),the feces and urine of rats at the corresponding time after intragastric administration of normal saline (blank control ) as samples . The accurate relative molecular weight ,formula and fragment information of the compounds were collected , and the compounds were speculated and i dentified by matching with the database and spectrum library of the instrument ,and comparing with the reference substance and relevant literature . RESULTS A total of eight compounds were identified in urine and feces of rats ,including 2 prototype components and 6 metabolites. Three compounds (including two prototype components as quercetin ,luteolin and one metabolite as luteolin or kaempferol) in feces of rats were identified ;five compounds (all metabolites ) in urine of rats were identified ,involving metabolites of quercetin ,luteolin or kaempferol . Metabolites mainly included the products of methylation ,glucuronidation and oxidation. CONCLUSIONS After intragastric administration ,the ethanol extract from the leaves of D. longan is mainly metabolized in rats through methylation ,glucuronidation and other pathways . The identified compounds are mostly metabolites of quercetin and luteolin .
