Objective To study the effectiveness of Ginsenoside on serum IL-17 and IL-23 in patients with systemic lupus erythematosus.Methods According to the digital table,86 patients with systemic lupus erythematosus (SLE) were randomly divided into two groups,the control group (n =43 cases) and the observation group (n =43 cases).The patients in the control group were treated through prednisone,while the patients in the observation group were treated through prednisone plus ginsenoside.They were all treated for three months,systemic lupus erythematosus activity index(SLEDAI),serum complement 3 (C3),IL-17 and IL-23 were evaluated.Results SLEDAI after treatment were significantly decreased,compared with the control group,the observation group decreased more significantly (t =2.73,P ＜ 0.05).Mtertreatment,serum C3 were significantly elevated,compared with thecontrol group,the observation group increased more significantly(t =3.04,P ＜0.05).After treatment,serum IL-17 and IL-23 were significantly reduced,and after treatment compared with the control group,the observation group decreased more significantly (t =2.13,3.06,all P ＜ 0.05).The rates of adverse reactions were 25.6％ in the control group and 7.0％ in the observation group.There was a statistically significance between two groups (x2 =4.89,P ＜ 0.05).Conclusion Ginsenoside can decrease serum IL-17 and IL-23 in patients with systemic lupus erythematosus.

BACKGROUND:Tissue-engineered bone, as an emerging method, is used to repair bone defects, but it is difficult to be used widely because of no nutrient metabolism of implants. Pre-vascularized tissue-engineered bone research is performed for this limitation. Forward-looking and procedural vascular construction prior to artificial grafting is perspective to supply the nutrient metabolism of implants.
OBJECTIVE:To analyze the research results and developmental tendency of pre-vascularized bone engineering in vitro using a multilevel analysis.
METHOD:Literature search was performed in CNKI database for Chinese literatures and PubMed database for English literatures from 2000 to 2012. The key words included“tissue-engineered bone, vascularization, implant, osteoblasts, endothelial cel s, co-culture”in Chinese, and“bone engineering, endothelial cel s, osteoblast, implant, cel s co-culture”in English. A review addressing pre-vascularized tissue-engineered bone was completed based on retrieved literature classified according to bone physiological studies, in vitro experimental research and material research.
RESULTS AND CONCLUSION:Total y 60 articles were included in result analysis. Studied have documented that microvascular regeneration in normal bone tissue has an important role in osteogenesis regulation. Current bone tissue engineering research is to simulate this physiological process of vascular regeneration in the human body, and lots of in vitro studies are designed to complete this angiogenic process in bone tissue engineering. It is confirmed that in vitro pre-vascular work is used for bone tissue engineering, especial y for in vivo survival and ossification of tissue-engineered bone, pointing out the developmental direction for the clinical application of tissue-engineered bone.

Objective:To establish a multidrug resistant human salivary adenoid cystic carcinoma cell line. Methods:Salivary adenoid cystic cells of the cell line SACC were exposed to 1 ?g/ml of DDP for 48 h at the interval of one month. 6 months later, the cell line was established and named SACC/DDP. MTT method was used to study the drug resistance of SACC and SACC/DDP cells against 4 chemotherapeutic agents(MTX, PYM, VCR, MMC). Flow cytometry was adopted to study the cell cycle distribution of the cells after treatment with 4 agents at different concentrations for 72 h. Results:The drug resistance of SACC/DDP cells against VCR,MTX,PYM and MMC was 2.9,2.4,1.1 and 1.8 times of that of SACC cells. The ratio of G0 cell number to G1 cell number in SACC/DDP cell line was smaller than that in SACC cell line after treatment with the 4 agents at different concentrations respectively.Conclusion:The multidrug resistant human salivary adenoid cystic carcinoma cell line can be estabished by exposing parent cell line SACC periodically to DDP.

Objective To compare the influence of different feeding mode on the immunoprophylaxis efficacy of the babies born to hepatitis B (HB) carrier mothers. Methods The babies born to HB carrier mothers received HB vaccine alone routinely or HB immunoglobulin (HBIG) plus HB vaccine immunoprophylaxis were followed up. Among infants with HB vaccine alone, 21 were breastfed and 40 bottle-fed, among those with HBIG and HB vaccine, 33 were breastfed and 135 bottle-fed. Results Among babies receiving HB vaccine alone, the positive rates of anti-HBs at 1,3,6,12 month of age are 4.8%, 42.9%, 57.9%, 80.9% in breastfed group, and 12.2%, 26.3%, 60.5%, 73.2% in bottle-fed group. Among those with HBIG and HB vaccine, the positive rates of anti-HBs at 1, 4, 7, 12 month of age are 72.7%,75.8%,77.4%,90.9% in breastfed group, and 77.0%, 72.9%,76.2%,90.4% in bottle-fed group. With HB vaccine alone, 1 infant in breastfed group and 3 in bottle-fed group, and with HBIG and HB vaccine, 0 in breastfed group and 4 in bottle-fed group were chronically infected at 1-year of age. There are no significant differences of the incidence of anti-HBs and immunoprophylaxis failure between breastfed and bottle-fed babies. Conclusion Breastfeeding doesn't pose a negative influence on the response of anti-HBs and the failure rates of the HB immunoprophylaxis in the infants born to HB carrier mothers

High-efficiency exhalation disinfection device for the patient infected with SARS can also meet the disinfection requirements of the patients with severe respiratory communicable diseases. Connected with the exhaust vent of the breathing mask or the respirator by corrugated tubes, this device gathers exhalation containing a large amount of causative agents through the completely leakproof ductwork and then expels purified air after multiplicate disinfection by high temperature, high pressure and chemical disinfectant. The device can prevent the patient with severe respiratory communicable disease from polluting their surrounding air and thus cut off the route of transmission, reduce the infection rate and the death rate of the person and medical personnel who has made intimmate contact with the patient.

Objective To study the effects of CD2-associated protein (CD2AP) on podocyte adhesion and extension ability and to explore its possible mechanism. Methods Conditionally immortalized murine podocyte cell line was cultured in RPMI 1640 medium at 33℃permissive conditions. The podocytes were transfected with CD2AP small interfering RNA (siRNA) and serambing sequences labeled with fluorescein were taken as control. The transfected podocytes were trypsinized and seed into collagen IV coated plates. The relative cell adhesion and cell area were examined 90 min later. Apoptotic rates of CD2AP siRNA transfected podoeytes and different PAN concentrations incubated podoeytes were detected by flow cytometer. The distribution of F-actin was observed under laser scanning confoeal microscope. Nephrin protein expression and its phosphorylation level were examined by immunofluorescence and Western blot. Results The relative ceil adhesion of CD2AP siRNA transfected podocytes was apparently lower than that of control group[(41.72±6.07)% vs (64.46±8.53)%, P<0.05]. The cell area analysis had the similar result. The apoptotic rate of CD2AP siRNA transfected podocytes was significantly higher than that of the controls [(5.73±0.61)% vs (3.26±0.45)%, P<0.05]. 100 mg/L PAN could markedly induce podocytes to apoptosis and impair cell adhesion ability (P<0.05). Nevertheless, no significant difference was found in cell body spreading (P>0.05). The distribution of F-actin in CD2AP depletion podocytes was apparently altered. The expression of nephrin protein and its phosphorylation level was conspicuously descended to some degree (P<0.05). Conclusions CD2AP depletion facilitates podocyte apoptosis and impairs cell adhesion function. Cytoskeleton confusion and nephrin signaling weakness caused by CD2AP depletion may he partly responsible for the decline of cell adhesion and spreading.
