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.

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.

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.

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.

Objective To investigate the clinical efficacy of Qishen Xiaodian Decoction combined with laser acupoint irradiation for treatment of recurrent Hen?ch-Sch?nlein purpura (HSP) in children. Methods Totally 120 cases of children with recurrent HSP were divided into treatment group and control group according to the digital random table method, with 60 cases in each group. The control group was given anti-allergy, hormones, immunosuppressive agents and other conventional treatment for 4 weeks, while the treatment group was treated with Qishen Xiaodian Decoction based on conventional treatment, 1 dose each day, morning and night (age 4–5 take 1/3 dose, age >5–10 take the half dose, and age >10–14 take the whole dose), for 4 weeks. Zusanli, Xuehai, and Sanyinjiao acupoints were under laser vertical irradiation, 12 min for each time, once a day for 2 weeks. The disappearing time of the main symptoms and the total effective rate of the two groups were compared. Peripheral blood contents of Th17 and Treg cells and serum interleukin-17 (IL-17), and transforming growth factor β1 (TGF-β1) level before and after the treatment were observed. The recurrence rate in 6 months and in 12 months of the two groups were compared. Results The disappearing time of rash, abdominal pain and joint swelling pain and kidney damage of the treatment group were less than those of the control group (P<0.01). The total effective rate was 95％(57/60) in treatment group, significantly higher than control group 80％ (48/60), with statistical significance (P<0.05). Compared with before treatment, Th17 cell content, serum IL-17 and TGF-β1 decreased, and Treg cell content increased after treatment of the two groups (P<0.01). Compared with the control group, contents of Th17 cell and serum IL-17 of the treatment group decreased (P<0.01). The recurrence rate was lower than that of the control group in 6 and 12 months after treatment, with statistical significance (P<0.05). Conclusion Based on the conventional western medicine treatment, Qishen Xiaodian Decoction combined with laser acupoint irradiation on recurrent HSP in children can quickly relieve symptoms and reduce the recurrence rate.

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.
