Objective To discuss the application and effect of predictive care in stage divided treatment and salvage of children's persistent status of epilepsy (SE).Methods Sixty-four children with SE were admitted to the First Peoples Hospital of Wenling in Zhejiang Province from December 2014 to December 2016 as the research objects, a controlled study was adopted, in which the stage divided therapeutic method was compared with the conventional method for treatment of SE, and the children were divided into an observation group and a control group, 32 cases in each group. Foresight treatment method was used in the observation group: the first stage of treatment (early treatment or pre-hospital treatment) was intravenous injection of the first-line drugs (benzodiazepines); the second stage of treatment (progressive stage treatment or initial treatment) mainly used epileptic drugs to prevent recurrence; the third stage treatment (referred to after the first-line drug in combination with one second line antiepileptic drug treatment, the disease was still unable to be controlled) adopted the mild hypothermia therapy to reduce the SE attack amplitude and decrease recurrence; in terms of aspects of predictive nursing measures, the respiratory tract nursing, basic nursing, the prediction of complications and their nursing, etc. were implemented. The routine nursing without care about the stages was carried out in the control group. The SE control time, skin lesions, false aspiration, lung infection, tongue bite, cerebral edema, etc. the incidenceof complications were observed in two groups of children.Results The SE control time was significantly shorter in observation group than that in the control group (minutes: 18.13±3.15 vs. 25.19±2.69,P < 0.05), and the incidence of complications was obviously lower in observation group than that in the control group [6.25% (2/32) vs. 28.13% (9/32),P < 0.05]. Conclusion Using different therapy at different stages of children SE combined with predictive care can effectively shorten the SE control time, decrease the incidence of complications and elevate the therapeutic and nursing effects.

AIMTo clone the gene of staphylococcal enterotoxin C2 and express it in the form of a soluble fusion protein in E. coli. Then the activation of SEC2 on mice lymphocyte and its lethal effects on tumor cells were studied.

METHODSStaphylococcus aureus SEC2 gene was cloned into GST gene fusion vector pGEX-4T-1. The resultant plasmid pGEX-4T-SEC2 was used to transform E. coli BL21, where the GST-SEC2 fusion protein was expressed efficiently. The rSEC2 protein was purified with Glutathione Sepharose 4B affinity column and digested with thrombin. The in vitro culture system was utilized to observe the activation of the SEC2 on mice lymphocyte and the lethal effects on tumor cells of the activated mice lymphocyte.

RESULTSThe proper gene of SEC2 was cloned and purified rSEC2 was obtained. The MTT results indicated that rSEC2 have strong ability to stimulate mice lymphocyte to proliferate with a dose-dependent manner. With the proliferation of mice splenic lymphocyte, rSEC2 has a strong lethal effect on tumor cells B16, K562 and K562-AD.

CONCLUSIONIn this study, the gene of SEC2 was cloned and the rSEC2 protein was obtained, which had strong lethal effect on tumor cells B16, K562 and K562-AD.

The filtrate of Staphylococcus aureus culture has been used in an ampule form named as staphylococcal enterotoxin C injection for cancer therapy in clinic for ten years in China and proved to be effective. The active constituent of three kinds of injections is claimed to be staphylococcal enterotoxin C2 (SEC2), and the content of SEC2 is used as quality control. However, the correct content of SEC2 was not known and the relative amount of SEC2 was very low because of the complicated components of the filtrate. In this research, we established a proper ELISA system for the detection of SEC2 in staphylococcal enterotoxin C injection, which will improve the quality control of the injection. We produced and identified polyclonal and monoclonal antibodies of SEC2 and established BA-ELISA method based on the method of sandwich ELISA. It was found that the BA-ELISA method had good specificity, sensitivity and reproducibility, and being able to detect SEC2 at concentration from 2 to 20 ng x mL(-1), with an average CV value of 5.08%. The SEC2 content in staphylococcal enterotoxin C injection was calculated. There is some difference between the actual and labeled contents in the injections.

OBJECTIVETo study the protective effects of polysaccharides from Dendrobium huoshanense (DHP) against CCl4-induced liver injury in mice.

METHODEighty male Kunming mice were randomly divided into normal control group, model control group, dextran control group, starch control group, hydrolyzate control group, three different dose of DPH groups consisting of high-dosage group, middle-dosage group and low-dosage group (200, 100, 50 mg x kg(-1)). Each group contained ten mice. The mice were treated with DHP via intragastric administration for 15 days before treatment of 50% CCl4 in olive oil for consecutive two days. Both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in serum and superoxide dismutase (SOD) activities and malondialdehyde (MDA) contents in liver tissues were determined in all groups. Immunohistochemistry was used to detect the expression of TNF-alpha in hepatic tissue. Hepatic histopathological examination was observed.

RESULTDHP effectively decreased the activities of ALT and AST in serum and the contents of hepatic MDA, and restored hepatic SOD activities in acute liver injury mice. Liver tissue damage induced by CCl4 was ameliorated in mice with DHP administration through histopathology examination. Furthermore, the expression of TNF-alpha was greatly decreased in groups treated with polysaccharides.

CONCLUSIONDHP has a significantly hepatoprotective effect on CCl4-induced acute liver injury in mice. Protective effect of DHP on the liver may be related to its function of scavenging free radicals and inhibiting lipid peroxidation and TNF-alpha expression.

OBJECTIVETo study the HIV infection risk perception, sexual behavior and condom use among college students who had sexual experiences.

METHODSUsing data generated from a survey on AIDS related knowledge and risk perception and sexual behavior (conducted in a coast city of Zhejiang province in 2003), with a questionnaire involving self-reporting history of sexual experience. Software SPSS 12.0 for windows was used for statistical analysis.

RESULTS47.0 percent of the 2785 students having had sexual experience did not feel that sexual experience was related to HIV risk while 51.3 percent them considered their sexual behavior was at much low risk. 80.5 percent of the students with sexual experience had ever used condoms, but only 16.0 percent used it consistently. There was no association between risk perception and condom use, but there was association between risk perception and intention for condom use.

CONCLUSIONThe college students having had sexual experience had low level of risk perception on HIV infection and had a high rate of ever condom use but low in consistent use. Extensive and detailed prevention intervention was needed to improve the safe sexual behaviors.

Hot-melt extrusion was applied to prepare mesoporous silica/ethylcellulose mini-matrix for sustained release, and fenofibrate was used as a model drug, ethylcellulose and xanthan gum were chosen as sustained-release agent and releasing moderator, respectively. This novel matrix obtained the controlled release ability by combining mesoporous silica drug delivery system and hot-melt extrusion technology. And mesoporous silica particle (SBA-15) was chosen as drug carrier to increase the dissolution rate of fenofibrate in this martix. Scanning electron microscope, transmission electron microscope, small angle X-ray powder diffraction and N2 adsorption-desorption were introduced to determine the particle morphology, particle size and pore structure of the synthesized SBA-15. The results showed that SBA-15 had a very high Brunauer-Emmett-Teller specific surface area, a narrow pore size distribution, large pore volume and a ordered two-dimensional hexagonal structure of p6mm symmetry. Differential scanning calorimetry and X-ray powder diffraction results demonstrated that fenofibrate dispersed in an amorphous state inside the pores of the mesoporous silica which contributed to the improvement in the dissolution rate. The drug release of mini-matrices was influenced by ethylcellulose viscosity grades and xanthan gum concentration, which increased with the increasing of xanthan gum concentration and decreasing of ethylcellulose viscosity. Mini-matrix containing 22% xanthan gum exhibited a good sustained release performance, and the drug release behavior followed the first-order kinetics.
