For uncontrolled hemorrhagic shock the traditional method and target of resuscitation may be harmful. The existing data supported a strategy of less aggressive interventions to those shock with uncontrolled hemorrhage until a decisive surgery begin. The choice of liquor for resuscitation remains in controversy. A combined application of crystalloid and colloid liquor seems to be reasonable and may be accepted by most physicians. It should be noted that the new resuscitation strategy may not be suitable to some kinds of trauma, such as traumatic brain injury, and its long-term effects on to the prognosis should be further evaluated.

Objective:To investigate relationships between serum chemerin and bone mineral density (BMD) in patients with newly diagnosed Graves disease (GD).Methods:A total of 120 newly diagnosed GD patients with a course more than 3 months were enrolled from the Department of Endocrinology between June 2013 and June 2015.Sixty age-and sex-matched healthy people served as a normal control.Serum levels of chemerin,β-crosslaps (β-CTX),and N-MID-osteocalcin (N-MID-OT) were measured by ELISA.Fat mass and BMD were evaluated by dual energy X-ray absorptiometry (DEXA).Results:Compared with the normal control,the fat mass,lean weight,fat mass index (FMI) and body mass index (BMI) in the GD group were decreased,and BMD in all skeletal sites was decreased.There was a positive correlation between them (all P<0.05).Serum level of chemerin was increased and it was positively correlated with β-CTX or N-MID-OT level and negatively correlated with fat mass,FMI or BMI in the GD group.There was a negative correlation between chemerin level and BMD in femoral neck,total hip,lumbar or right forearm distal 1/3 (rs=-0.352,-0.279,-0.379,-0.289,-0.394;P<0.05).After adjusting for age,fat mass or BMI,the correlation of chemerin with total hip or bone mineral density remained significant (rs=-0.273,-0.378;P<0.05).Multiple linear regression analysis revealed that chemerin or BMI was correlated with BMD (P<0.05).Conclusion:The decrease of bone mineral density in patients with GD is not only related to the direct or indirect effect of excessive thyroid hormones on systemic and osteoblastic cells,but it is also related to the negative regulation of bone metabolism due to the elevated chemerin level.

Methods Total of 198 isolates of E. coil and K. pneumoniae were isolated from five hospitals in Hangzhou. ESBLs-producing isolates were detected by inhibitor-potentiated disc diffusion test, Agar dilution method was used to determine the minimum inhibitory concentrations (MIC) of cefotaxime and ceftazidime.ESBLs genes were analysed by isoelectric focusing (IEF) assay and PCR initially,genotypes were determined by sequencing. Results 51 isolates (25.76%) from 198 E. coil and K. pneumoniae strains were obtained. In ESBLs producers, the ESBLs types of SHV, TEM, CTX-M were 17.65%,84.31% and 80.39% respectively. genotypes were: SHV 11,12;TEM 1;CTX M 3and CTX M 3 like, CTX M 13,14. respectively. Conclusions CTX M type were the major genotypes of ESBLs in klebsiella pneumoniae and eschrichia coli isolated in Hangzhou city.

Objective To investigate the methylation status of the promoter of RASSF1A gene in the tissues of bladder cancer and renal carcinoma and its role in tumorigenesis. Methods Methylation specific PCR (MSP) was used to examine the methylation status of RASSF1A in bladder cancer and renal carcinoma.The specimen included 45 cases of bladder cancer tissues and paired adjacent normal tissues from cystectomy,9 cases of bladder cancer tissues from microresection,3 cases of normal bladder tissues from people without tumor,12 cases of renal carcinoma tissues and paired adjacent normal tissues. Results 30 of 54(55.6%)bladder cancer tissues showed RASSF1A gene aberrant methylation.Of which,26 of 45 ( 57.8 %) bladder cancer tissues from cystectomy showed aberrant methylation,while one of the paired normal tissues showed gene methylation,4 of 9 (44.4%) bladder cancer tissues from microresection showed gene methylation.Eight of 12(66.7%)renal carcinoma tissues showed aberrant methylation,while none of the paired adjacent normal tissues showed gene methylation.None of the three normal bladder tissues showed aberrant methylation.There was no significant correlation between the methylation status and the clinical pathological parameters in bladder cancer tissues from cystectomy,though there was a trend that more frequent methylation was detected in higher stage bladder cancer. Conclusions Hypermethylation of RASSF1A gene in bladder cancer and renal carcinoma suggeste its possible role in the tumorigenesis of both tumors.

Objective To investigate the potential effect of the redox state of plasma factor Ⅺ (FXI) on the pathogenesis of elderly diabetic hypercoagulability and macroangiopathy.Methods The plasma levels of reduced FXI were detected in elderly type 2 diabetic(T2DM)patients with/without macroangiopathy (T2DM group/DMAP group) and healthy subjects (control group),and variables associated with reduced FXI were analyzed.Results Elderly patients with T2DM had higher plasma levels of reduced FXI as compared with healthy controls.The level of reduced FXI was significantly higher in patients with macroangiopathy than without macroangiopathy [control group:(80.6± 15.6) %,T2DM group:(94.7 ± 16.0) %,DMAP group (142.6 ± 36.5) %,all P< 0.05].The multiple stepwise regression analysis showed that plasma levels of triglyceride,cholesterol and HDL-cholesterol were the independent predictors for reduced FXI.Conclusions The plasma level of reduced FXI is increased in elderly T2DM patients with macroangiopathy.The abnormality of lipid profiles may associate with the increment of reduced FXI.These findings maybe provide the novel mechanisms for diabetic hypercoagulability and macroangiopathy.

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.

In this study, the buffering capacity of amphiphilic pH-sensitivity copolymer poly(2-ethyl-2-oxazoline)-cholesteryl methyl carbonate (PEOZ-CHMC) was evaluated. The ammonium sulfate gradient method was used to prepare doxorubicin hydrochloride (DOX x HCl)-loaded liposomes (DOX-L), and then the post-insertion method was used to prepare PEOZ-CHMC and polyethylene glycol-distearoyl phosphatidyl ethanolamine (PEG-DSPE) modified DOX x HCl-loaded liposomes (PEOZ-DOX-L and PEG-DOX-L). The physico-chemical properties, in vitro drugs release behavior, cellular toxicity and intracellular delivery of liposomes were evaluated, separately. The results showed that PEOZ-CHMC has a satisfactory buffering capacity. The sephadex G-50 column centrifugation method and dynamic light scattering were used to determine the encapsulation efficiency (EE) and particle size of liposomes. The EE and particle size of DOX-L were (97.3 ± 1.4) % and 120 nm, respectively, and the addition of PEOZ-CHMC or PEG-DSPE had no influence on EE and particle size. The zeta potentials of three kinds of liposomes were negative. The release behavior of various DOX liposomes in vitro was investigated by dialysis method. In phosphate buffer solution (PBS) at pH 7.4, DOX x HCl was released from PEOZ-DOX-L in a sustained manner. While in PBS at pH 5.0, the release rate of DOX x HCl from PEOZ-DOX-L increased significantly, which suggested DOX x HCl was released from PEOZ-DOX-L in a pH-dependent manner. The intracellular delivery of liposomes was investigated by confocal laser scanning microscopy (CLSM). The CLSM images indicated that PEOZ-DOX-L showed efficient intracellular trafficking including endosomal escape and release DOX x HCl into nucleus, as well as the DOX-L and PEG-DOX-L had no this effect. The cytotoxicity of liposomes against MCF-7 cells was detected by using MTT assay. The results showed that antiproliferative effects of PEOZ-DOX-L enhanced with pH value decreased, whereas DOX-L and PEG-DOX-L did not have any significant difference in inhibitions at different pH conditions. Therefore, the problems of the inhibition of cellular uptake of liposomes and the failed endosomal escape of pH-sensitive liposomes by PEG chain can be overcome by the pH-sensitive liposomes constructed by PEOZ-CHMC.
