Objective To determine the transfection of PTEN gene in human ovarian carcinoma SKOV3 cells by ultrasound mediating and contrast agent′s enhancing, and to explore the mechanism of PTEN gene inhibiting the tumor cells′ invasion. Methods After addition of PTEN gene and 5 ?l lipofectamine,human ovarian carcinoma SKOV3 cells on 6-well plates were explored to ultrasound for 60 s in the presence(200 ?l) of ultrasound agent. The invasiveness of transfected cells was measured quantitatively by Matrigel invasion assays(Transwell chamber) after 48 h. Results The invasiveness of SKOV3 cells transfected by ultrasound-mediated PTEN gene was significantly declined compared with that of the controls. Conclusions The transfection of PTEN gene into SKOV3 cell can inhibit their invasion.The gene transfection can be enhanced by ultrasound and contrast agent,which may be expected to be a new means of clinical gene therapy.

Objective To observe the immunologic function of critically ill newborn and the relative function of nuclear factor kappa B(NF-?B).Methods The critically ill group contained 50 cases,and 25 cases from healthy newborns were used as control group.Blood samples were collected in each case,levels of cytokine interleukin(IL)-4,interferon(IFN)-?,tumor necrosis factor(TNF)-? and NF-?B were detected.Result Compared with control group,NF-?B of the critically ill newborn activated and the cytokine were disorder,and IL-4 and TNF-? increased,but IFN-? decreased.Conclusions Critically ill newborn exist immune functional disorder.Furthermore,NF-?B activation may be involved in the process in infants with critically illness.

Objective To investigate the effects of 1,25-dihydroxyvitamin D_3 on the bone metabolism of primary osteoporosis.Methods Female New Zealand white rabbits aged 8 months were ovariectomized bilaterally as models of postmenopausal osteoporosis and they were randomly divided into 4 groups: pseudo-ovariectomized group(Sham group),ovariectomized group(OVX group),calcii gluconas group(OC group),calcii gluconas and 1,25-dihydroxyvitamin D_3 group(OCR group).Both female New Zealand white rabbits aged 3 years and male New Zealand white rabbits aged 4 years were selected as models of senile osteoporosis.They were randomly divided into 3 groups:control group,calcii gluconas group(Calcium group),calcii gluconas and 1,25-dihydroxyvitamin D_3 group(CR group).Rabbits in OC group and Calcium group were given calcii gluconas and in OCR group and CR group were given calcii gluconas and 1,25-dihydroxyvitamin D_3.The bone metabolic biochemical indexes were determined among all the experimental animals after they were given drug for 8 weeks.Results After the experimental animals were given drug for 8 weeks,the serum calcium(Ca),serum phosphorus(P) and alkaline phosphatase(ALP) of OCR group were significantly higher than those of OVX group and OC group(all P

Objective To study the effects of modified Sanxiang Decoction on gastrointestinal transmission function of patients with functional bloating (FB). Methods Sixty cases of FB patients were randomly divided into treatment group (40 cases) and control group (20 cases). Treatment group was given modified Sanxiang Decoction, while control group was given placebo granules, one bag each time. Twice a day, taking it after mixing it with water. Gastrointestinal symptoms, 48 h GITT, and adverse reactions were recorded. Results There was statistical significance in TCM symptom scores between before and after treatment in the two groups (P<0.05). After treatment, the total score of abdominal distension, belching, anorexia and TCM symptoms of the treatment group were lower than the control group, with statistical significance (P=0.000, 0.000, 0.010, 0.003). The total effective rate was 82%(33/40) in the treatment group, 30%(6/20) in thecontrol group;the treatment group was better than the control group (P<0.05). A total of 30 patients completed gastrointestinal transit test, of which delayed 48 h GITT pass rate accounted for 54% (16/30). Compared with the control group, the 48 h GITT of the treatment group was more obviously improved than that of the control group with statistical significance (P=0.002). There were no significant adverse reactions in both groups. Conclusion Most of FB patients have the problem of abnormal intestinal motility. Modified Sanxiang Decoction can improve the symptoms of patients with FB, promote gastrointestinal motility, and improve intestinal transmission function.

To purify the protein encoding the small capsid protein (SCP) of KSHV and analyze its immunogenicity, the carboxyl terminus of orf65 of Kaposi's sarcoma associated-herpesvirus (KSHV) was expressed in a prokaryotic expression system. The expression of recombinant E. coli containing pQE-80L-orf65 was induced by isopropyl-β-D-thiogalactopyranoside (IPTG) and the fusion protein was purified by chromatography. The expressed protein and its purified product were identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and showed that 9 kDa was the expected size of the purified orf65 protein. The antiserum was produced in rabbit which was immunized by purified orf65 protein. An ELISA assay was established to analyze the immunogenicity of the purified orf65 protein. The ELISA analysis demonstrated that orf65 protein has strong immune activity, and the immune activity of polyclonal antibody against orf65 was more than 4 fold higher than that in the serum of the non-immunized rabbit. These results demonstrate that purified orf65 protein has very strong immunogenicity and can be used in screening KSHV infection in the general population using ELISA.
