Patients with systemic lupus erythematosus (SLE)are susceptible to influenza virus infection due to autoimmune disorder,use of glucocorticoids and the immunosuppressive agents.Influenza virus infection affects the disease stability,and the mortality of influenza virus infection in SLE patients is 5 times higher than that in general people infected by influenza virus.Vaccination is the most effective measure to prevent influenza virus infection.There is lack of studies on the influenza immunization in SLE patients in China,so this paper reviews prevention effect and safety of inoculation,the immune response to vaccine as well as the factors influencing immune response in influenza vaccination for SLE patients.

OBJECTIVE To explore the effect of vacuum packaging technique for storing sterilized packs in order to extend the period of valid storing.METHODS From 420 sterilized packages 210 were randomly taken as a test group,and the other 210 packages as the control group.According to aseptic techniques the packages of test group were vacuumized and the control group was packed as by outine protocol.Two groups were simultaneously stored in aseptic closet,and then regularly taken out 30 samples from two groups respectively for microbial(culturing).RESULTS Bacterial growth was seen in the control group at first month.But none of the specimens in test group showed any microbial growth until the eighth month.There was a statistically significant difference((P

OBJECTIVE To explore the effect of smearing catheter surface with chloramphenicol for preventing catheter -associated urinary tract infections. METHODS Totally 100 cases of preoperative patients needed for indwelling urethral catheters were randomly grouped, 50 of 100 cases as test group, and the others 50 cases as the control group. Catheters after smearing surface with chloramphenicol were inserted using aseptic technique in the test group, urinary catheters without using chloramphenicol were inserted in the control group according to routine aseptic technique protocol, and then regularly taken out urinary specimen from two groups respectively for microbial culture. RESULTS The observation showed bacterial growth positive rate was 30%, and 66.7%, respectively in the control group, but positive rate was 6.7%, and 30%, respectively in the test group after the seventh day and the tenth day. There was a statistic significant difference (P

In this study, the effects of catalase (CAT) inhibitor aminotriazole (ATZ) on alcohol-induced acute liver injury were investigated to explore the potential roles of CAT in alcoholic liver injury. Acute liver injury was induced by intraperitoneal injection of alcohol in Sprague Dawley (SD) rats, and various doses of ATZ (100-400 mg/kg) or vehicle were administered intraperitoneally at 30 min before alcohol exposure. After 24 h of alcohol exposure, the levels of aspartate transaminase (AST), alanine transaminase (ALT) and lactate dehydrogenase (LDH) in plasma were determined. The degree of hepatic histopathological abnormality was observed by HE staining. The activity of hepatic CAT, hydrogen peroxide (H₂O₂) level and malondialdehyde (MDA) content in liver tissue were measured by corresponding kits. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in plasma were determined by ELISA method. The results showed that treatment with ATZ dose-dependently suppressed the elevation of ALT, AST and LDH levels induced by alcohol exposure, and that ATZ alleviated alcohol-induced histopathological alterations. Furthermore, ATZ inhibited the activity of CAT, reduced hepatic levels of H₂O₂and MDA in alcohol exposed rats. ATZ also decreased the levels of plasma TNF-α and IL-6 in rats with alcohol exposure. These results indicated that ATZ attenuated alcohol-induced acute liver injury in rats, suggesting that CAT might play important pathological roles in the pathogenesis of alcoholic liver injury.
