Objective To compare the effect of different positive end-expiratory pressures (PEEPs) on the efficacy of volume therapy guided by global end-diastolic volume index (GEDVI) and central venous pressure (CVP) in patients with septic shock.Methods Twenty-five patients with septic shock complicated with respiratory failure,of both sexes,aged 18-64 yr,were enrolled in the study.Their APACHE [[scores were 13-31.The patients were endotracheally intubated and underwent volume-controlled ventilation,PEEP was 5-15 cmH2O,and pulse oxygen saturation was maintained > 90 %.The patients were divided into low PEEP (5-10 cmH2 O) group and high PEEP (11-15 cmH2 O) group depending on the different PEEP levels.6 % hydroxyethyl starch (200/0.5)6 ml/kg was infused over 30 min for volume therapy.Right internal jugular vein or subclavian vein was cannulated for CVP monitoring,and GEDVI was continuously monitored by pulse indicator continuous output monitoring (PiCCO) technology.CVP and GEDVI were recorded before and after volume therapy and the changing rate was calculated.Results Compared with CVP and GEDVI before volume therapy,CVP and GEDVI were significantly increased after volume therapy in low PEEP group (P < 0.05),and GEDVI was increased after volume therapy (P < 0.05) and no significant change was found in CVP after volume therapy in high PEEP group (P > 0.05).Compared with low PEEP group,the changing rate of CVP was significantly decreased (P < 0.05),and no significant change was found in the changing rate of GEDVI in high PEEP group (P > 0.05).Conclusion High PEEP can decrease the efficacy of volume therapy guided by CVP,while exerts no effect on the efficacy of volume therapy guided by GEDVI in patients with septic shock.

To study the preventive effect of Grifola frondosa on nonalcoholic steatohepatitis (NASH). The rat model of NASH was established by feeding high-fat diets for 12 weeks and intervened with 0.5 g · kg(-1) · d(-1) and 1.0 g · kg(-1) · d(-1) of C. frondosa powder suspensions. The degrees of hepatocyte fatty degeneration and inflammation were observed under the optical microscope with routine HE staining. The NAFLD activity scores (NAS) were calculated. Serum ALT, AST and hepatic TG and CHOL were tested by the biochemical method. The hepatic MDA was examined by thiobarbituric acid method. The hepatic SOD was tested by the xanthine oxidase test. The hepatic GSH-PX activity was determined by the dithio-nitrobenzoic acid method. Hepatic TNF-α and IL-6 were detected by the enzyme-linked immunosorbent assay (ELISA). The NASH model group induced by high-fat diets showed higher hepatic NAS, ser- um ALT, AST, CHOL and hepatic TG, CHOL, MDA, TNF-α, IL-6 (P < 0.01 or P < 0.05) and lower serum TG and hepatic SOD, GSH-PX (P < 0.01, P < 0.05) than the normal control group. After being intervened with different doses of G. frondosa, the NASH group revealed significantly lower hepatic NAS, serum ALT and hepatic TG, CHOL, MDA, TNF-α and IL-6 (P < 0.05) and higher hepatic SOD, GSH-PX (P < 0.05) than the model group. G. frondosa may prevent the further development of NASH by improving the disorder of lipid metabolism in rats with NASH induced by high-fat diets, relieving the level of oxidative stress and reducing the generation of inflammatory cytokines.

Early diagnosis of sepsis helps make effective clinical decisions and improve the survival rate of patients with severe infection. However, the timely and accurate diagnosis of sepsis is still a great challenge in clinic. In order to settle the very problem, the scientists in the world have made a lot of exploration and research in the field of rapid molecular identification of pathogens. Nowadays, the nucleic acid detection of sepsis is mainly composed of 3 types of methodological strategies, either based on positive blood culture, single colonies, or directly on blood specimens. This paper presents a comprehensive overview of advances in the research of early detection of bacterial nucleic acid as molecular diagnosis of sepsis.

Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

OBJECTIVETo investigate the expression of Caspase-3 and Hsp70 in rabbits after severe traumatic brain injury (TBI) and to explore the feasibility of its application in estimation of injury time in forensic medicine.
METHODSA rabbit model of heavy TBI was developed by high velocity impact on the parietal bone with an iron stick. Totally 8 healthy adult New Zealand white rabbits were randomly divided into control group (n equal to 2) and injury group (n equal to 6). Four hours after injury, tissue specimens from the parietal lobe, temporal lobe, occipital lobe, cerebellum and brainstem were harvested to detect the expression of Hsp70 and Caspase-3 by immunohistochemistry. Besides, the gray values of cells positive for Hsp70 and Caspase-3 were analyzed with an image analyzer.
RESULTSImmunohistochemistry staining demonstrated a low level of Caspase-3 and Hsp70 expression in normal control group. While in injury group, both the Caspase-3 and Hsp70 expression was significantly elevated (P less than 0.05). Positive cells gathered around the lesion focus. Occipital lobe and cerebellum had fewer positive cells while temporal and brainstem had the fewest.
CONCLUSIONThe expression of Caspase-3 and Hsp70 at an early stage following severe TBI is characteristic and can be applied to estimate the time of injury.

The skin of Bufo bufo gargarizans, originated from Bufo bufo gargarizans Cantor (Bufonidae), is widely used in traditional Chinese medicine for the treatment of hepatoma, lung cancer and etc. The preparation of the aqueous components has significant therapeutic effect against the digestive tract cancer. The water-soluble chemical constituents in the skin of Bufo bufo gargarizans were then investigated to make clear the active compounds. Six compounds were isolated and purified by recrystallization and column chromatography on silica gel and ODS, their structures were elucidated as 4-amido-3-hydroxymethyl-cyclooctylamidezotetra-alpha-furanone (I), bufogargarizanine C (II), bufothionine (III), dehydrobufotenine hydrobromide (IV), suberic acid (V) and succinic acid (VI) on the basis of physicochemical properties and spectral data (UV, IR, 1H NMR, 13C NMR and MS). Of the above compounds, compounds I and II are new compounds and named bufogargarizanine B and C, respectively.

Currently available monotherapies of oral nucleoside/nucleotide analogs or interferon are unable to achieve a sustained and effective response in most of patients with chronic hepatitis B (CHB). The objective of the present study was to compare the efficacy and safety of pegylated interferon (Peg-IFN) alpha-2b plus adefovir dipivoxil combination therapy versus Peg-IFN alpha-2b alone. Sixty-one HBeAg-positive chronic hepatitis B patients were randomized to receive Peg-IFN alpha-2b alone (1.5 μg/kg once weekly) or Peg-IFN alpha-2b plus adefovir (10 mg daily) for up to 52 weeks. Efficacy and safety analyses were performed on all participants who received at least one dose of study medication. The rate of HBeAg seroconversion and undetectable HBV-DNA were evaluated after 52 weeks of therapy. At the end of treatment, 11 of 30 (36.7%) patients receiving combination therapy achieved HBeAg seroconversion versus 8 of 31 (25.8%) in the monotherapy group (P=0.36). In contrast, the percentage of patients with undetectable serum HBV DNA was significantly higher in the combination group than in the monotherapy group (76.7% vs. 29.0%, P<0.001). Thyroid dysfunction was more frequent in the combination group than in the monotherapy group (P<0.05). In HBeAg-positive CHB, combination of Peg-IFN alpha-2b and adefovir for 52 weeks resulted, at the end of treatment, in a higher virological response but without significant impact on the rate of HBeAg seroconversion and possibly an adverse effect on thyroid function.
