Objective The aim of study is to explore the TORCH infection status on the pre-pregnancy women and analyze the relationship with pregnancy outcome in Hongkou District,Shanghai,and provide the reference for the eugenic and superi-or nurture.Methods Enzyme linked immunosorbent assay (ELISA)was used to detect the specificity antibodies to Toxo-plasma (TOX),Rubelavirus (RUV),Cytomegalovirus (CMV)IgG and IgM in sera of the 3 500 pre-pregnant women in Hongkou District,Shanghai.Chi-square test was used for comparative analysis of the different rates.Results The positive rate of TOX-IgG,TOX-IgM,RV-IgG,CMV-IgG and CMV-IgM in pregnancy women from Hongkou district were 1.37%, 0.34%,89.7%,96.2% and 0.60% respectively.The total positive rate of TOX and (or)CMV IgM was 0.94%.According to age group,the results showed that TORCH infections with three pathogens associated with the pre-pregnancy women’s age,and the difference was statistically significant (χ2=102.9,P<0.01).The abnormal pregnancy rate of TORCH infec-tion-positive pregnancy women (25.0%,3/12)was higher than that of TORCH-negative pregnancy women (6.62%,27/408),and the difference was statistically significant (χ2 =4.43,P=0.04).Conclusion The infection opportunity of TORCH in pregnant women in Shanghai Hongkou district was obviously existent and the TORCH infection status could effect on pregnancy outcome.TORCH testing has important practical significance as a routine examination of the pre-preg-nancy healthy service.

Objective:To evaluate the biological functions and underlying mechanisms of transcription factor PAX5 in promoting cell proliferation and anti-apoptosis in multiple myeloma cells.Methods:a PAX5 knockdown cell line was established by stable transfection of vector-based PAX5-siRNA into multiple myeloma IM9 cells.The expressing level of PAX5,p53,XBP-1 and c-Myc was examined by either or both Western blot and RT-PCR for the targets.Cell proliferation and apoptosis were assayed by MTT and flow cytometry,respectively.Results:PAX5 was expressed selectively in IM9 cells,but neither in another common used multiple myeloma KAS6 cells nor in the prostate cancer cells DU145 and PC3.Knockdown PAX5 led to a significant up-regulation of p53 and XBP1,but decreased c-Myc expressions in IM9 cells that were correlated with the increased sensitivity of drug-induced apoptosis and decreased proliferation rates when compared to the control cells.Conclusion:PAX5 is specifically expressed in IM9 cells,which promotes cell proliferation and anti drug-induced apoptosis.In addition to inhibiting the expression of p53 and XBP-1,PAX5 is found to induce expression of oncogene c-Myc in IM9 cells,and this finding indicates an undiscovered signal pathway that may contributes to the malignancy of Multiple Myeloma cells.

Objective To investigate the effect of the serums containing Xuefuzhuyu capsules and Xuesetong capsules on the proliferation of vascular smooth muscle cells (VSMC) induced by 1ysophosphatidie acid (LPA). Methods Rat VSMCs were obtainded by tissue-piece inoculation and divided into seven groups:blank serum group, Xuefuzhuyu (Xuesetong) capsules-containing serum group, LPA+ Xuefuzhuyu (Xuesetong, captopril) containing serum group and LPA+blank serum group. Effects of different groups on the proliferation of VSMCs was evaluated by MTT colorimetry. Analysis of cell cycle and DNA content were performed by flow cytometry. Results The optical density (OD) and the S phase fraction (SPF) of LPA+blank serum group and Xuefuzhuyu capsules-containing serum group were more increased than the blank serum group (P 0.05, P 0.05). Conclusion Xuefuzhuyu capsules and LPA promoted the proliferation of VSMCs in vitro. Xuefuzhuyu and Xuesetong capsules can inhibit the proliferation induced by LPA, and effect of Xuesetong capsules was greater. Part of the mechanism may be associated with the inhibition of DNA synthesis and preventing the transition from G0/G1 to S phase of VSMCs.

Purpose To investigate the clinical outcome of induced membrane technique for treatment of post-traumatic tibial osteomyelitis.Methods A retrospective analysis was made on 17 cases of post-traumatic tibial osteomyelitis admitted from August 2011 to October 2012.There were 13 males and 4 females aged 19-67 years (mean,40.9 years).Mean length of bone defect was 6.7 cm (range,2.0-18.5 cm).Surgical treatments were performed including phase Ⅰ surgical debridement and antibiotics-loaded bone cement impregnation to induce a membrane and phase Ⅱ bone defect reconstruction by intramembranous bone grafting.Clinical effect of the treatment was evaluated.Results Bone healing was detected at the 27-month follow-up (range,24-32 months).Radiographic healing was obtained 4-6 months after operation.Two cases of recurrent infection were noted after phase Ⅰ surgery and had another debridement.External fixator proximal pin track infection occurred in one case and infection was controlled by hardware removal and dressing change.There was one case of metal rejection,two function disorders,one clubfoot,and one ankle stiffness.Conclusion Induced membrane technique is effective in the treatment of post-traumatic tibial osteomyelitis,especially in lone bone defect reconstruction,but limb functional complications are worth consideration during treatment.

Objective To explore the relationship between single nucleotide polymorphisms (rs12953-717) of SMAD7 and susceptibility of non-small cell lung cancer (NSCLC) in Chinese Han population.Methods A single nucleotide polymorphisms (rs12953717) from SMAD7 was detected via Sequenom system in 528 NSCLC cases and 762 healthy controls.Data was statistically analyzed by unconditional Logistic regression method.Results rs12953717 had significant differences between non-small cell lung cancer patients and the controls.Compared with CC/TT (CC combined with TT) genotype,the adjusted odds ratio for the CT genotype was 4.107 (95％ CI:3.206 ～ 5.260,P =0.000 1).Smokers had a 2.004 odds ratio (95 ％ CI =1.583 ～ 2.537,P =0.000 1) of NSCLC compared with the controls.There was a 10.074-fold increased risk of NSCLC among the subjects with CT genotype and smokers.Conclusion The polymorphism of rs12953717 may have relation with risk of NSCLC.Heterozygote (CT) is a susceptibility genotype of NSCLC.Smoking is one of the risk factors of NSCLC.Smoking and CT genotype have synergistic effects on NSCLC susceptibility.

AIM To investigate whether pretreatment with prostaglandin E 1 (PGE 1) might protect myocardium against peroxidative injury in early phase and in delayed phase. METHODS Rats were pretreated with PGE 1 (25 or 150 mg?kg -1 ). Isoproterenol (ISOP)(80 mg?kg -1 ) were injected peritoneally (ip) to induce acute myocardial infarction 20 minutes (early phase) or 24 hours (delayed phase) after pretreatment. Hearts were removed punctually 24 hours after ip ISOP and were assayed for content of malonaldehyde (MDA), activity of glutathione peroxidase (GSH Px) and superoxide dismutase (SOD). RESULTS ISOP caused myocardial injury with increased MDA content and SOD activity, and decreased GSH Px activity. Pretreatment with PGE 1, at each dose and in both phase, decreased the MDA content ( P

Professor YU Ren-cun believes that the responsibility of cough and asthma of lung cancer patients not only lies in the lungs, but also relates with spleen, kidney, heart and liver. Treatment should focus on the whole body and overall conditioning. Syndrome can be divided into 4 types: qi deficiency with phlegm resistance, yin deficiency with toxic heat, qi stagnation with blood stasis, and lung and kidney deficiency. Clinical treatment should pay attention to the combination of disease and syndrome, which can achieve satisfactory efficacy.
