Objective To evaluate the expression of KAII (CD82) gene inhibited by small interfering RNA (siRNA) in human pancreatic cancer cell line T3. Methods Four sequences of siRNA including A, B,C, D were designed, which were based on the KAI1 gene sequence using online RNA interfering designing software and lentivirus vector was built. Then they were used to transfect T3 cells by liposome 2000 and virus titer was determined. Empty vector containing siRNAd1 lentivrus particle ( MOI =5) was also used to infect T3 cells. The expression of CD82 mRNA was detected by real-time PCR. Results The expression of CD82 mRNA in normal control group, empty vector group, A group, B group, C group, D group were 1. 398 ±0.242,1. 311±0.048, 0. 664 + 0. 093, 0. 345 ± 0. 032, 0. 641 ± 0. 049 and 0. 147 ± 0. 049, respectively, the difference between the expression of CD82 mRNA in empty vector group and that of A, B, C, D groups was significant (P<0.01 ). Conclusions RNAi was able to inhibit the expression of KAI1 gene CD82 in human pancreatic cancer cell line T3.

Objective To introduce a locating device for the entry point of intramedullary nail based on the inertial navigation technology,which utilizes multi-dimensional angle information to assist in rapid and accurate positioning of the ideal direction of femoral anterograde intramedullary nails'entry point,and to verify its clinical value through clinical tests.Methods After matching the locating module with the developing board,which are the two components of the locating device,they were placed on the skin surface of the proximal femur of the affected side.Anteroposterior fluoroscopy was performed.The developing angle corresponding to the ideal direction of entry point was selected based on the X-ray image,and then the yaw angle of the locating module was reset to zero.After resetting,the locating module was combined with the surgical instrument to guide the insertion angle of the guide wire.The ideal direction of entry point was accurately located based on the angle guidance.By setting up an experimental group and a control group for clinical surgical operations,the number of guide wire insertion times,surgical time,fluoroscopy frequency,and intraoperative blood loss with or without the locating device was recorded.Results Compared to the control group,the experimental group showed significant improvement in the number of guide wire insertion times,surgical time,fluoroscopy frequency,and intraoperative blood loss,with a statistically significant difference(P<0.01).Conclusion The locating device can assist doctors in quickly locating the entry point of intramedullary nail,effectively reducing the fluoroscopy frequency and surgical time by improving the success rate of the guide wire insertion with one shot,improving surgical efficiency,and possessing certain clinical value.

OBJECTIVETo evaluate the effects of ALT, HBsAg and HBV DNA at the baseline, 4 and 12 weeks after lamivudine treatment on the long term (104 weeks) response in e antigen-negative chronic hepatitis B patients.
METHODS127 adult e antigen-negative chronic hepatitis B patients were enrolled in this study. All patients received treatment on LAM 100 mg/d for at least 104 weeks. The liver function, serum HBV markers and HBV viral load were regularly checked during the treatment. The effects of ALT, HBsAg and HBV DNA at the baseline, 4 and 12 weeks after lamivudine treatment on the response at 104 weeks were statistically analyzed.
RESULTSThe proportion of patients with serum HBV DNA less than 1000 copies / ml at 104 weeks after LAM treatment was 50.0% and 86.8% in patients with baseline ALT less than 5 ULN and ALT is more than or equal to 5 ULN, respectively (P less than 0.01). In patients with baseline HBsAg less than 2000 COI and HBsAg is more than or equal to 2000 COI, the proportion of patients with serum HBsAg less than 500 COI at 104 weeks after LAM treatment was 19.1% and 17.5%, respectively (P more than 0.05). the HBsAg serological conversion rates were respectively 2.1% and 2.5% , respectively (P more than 0.05), the proportion of patients with serum HBV DNA less than 1000 copies/ml was 61.7% and 67.5%, respectively (P more than 0.05). In patients with baseline HBV DNA less than 10(6) copies/ml and HBV DNA is more than or equal to 10(6) copies/ml, the proportion of patients with HBV DNA less than 1000 copies/ml were statistically different at 4 weeks and 12 weeks after treatment, however, the proportion of patients with HBV DNA less than 1000 copies/ml at 104 weeks after LAM treatment was 62.7% and 67.1%, respectively (P more than 0.05). In patients with HBV DNA less than 1000 copies/ml and HBV DNA is more than or equal to 1000 copies/ml at 4 weeks after treatment, the proportion of patients with HBV DNA less than 1000 copies/ml at 104 weeks after LAM treatment was 70.7% and 60.9%, respectively (P more than 0.05). In patients with HBV DNA less than 1000 copies/ml and HBV DNA is more than or equal to 1000 copies/ml at 12 weeks after treatment, the proportion of patients with HBV DNA less than 1000 copies/ml at 104 weeks after treatment was 78.8% and 38.1%, respectively (P less than 0.01).
CONCLUSIONe antigen negative chronic hepatitis B patients with baseline ALT is more than or equal to 5 ULN and HBV DNA less than 1000 copies/ml at 12 weeks after treatment have better virological response at 104 weeks after LAM treatment. The baseline HBsAg and HBV DNA load are associated with the virological response at 104 weeks after LAM treatment.

OBJECTIVETo explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats.
METHODS60 female SD rats were randomly divided into 3 groups: control group, model group and treatment group. The model and treatment groups were established by subcutaneous injection of DHEA, while the treatment group was given RGZ. The serum hormone values, pathohistology of ovarian structure of rats, ovarian ultrastructure and the expressions of TGF-β(1) and CTGF were detected.
RESULTSThe PCOS model was established successfully. The expression intensity of TGF-β(1) and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400, respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133; after treatment with rosiglitazone, the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group (P<0.05, P<0.001). The values in serum of the PCOS groups were 3.749±2.054 and 0.265±0.129, and 1.914±1.801 and 0.096±0.088 in the control group which had statistically significant difference (P<0.05, P<0.001). After treatment with rosiglitazone, the values were 2.3100±1.825 and 0.112±0.187 and were significantly different with those of the model group (P<0.05, P<0.001).
CONCLUSIONTGF-β(1) and CTGF play an important role in the development of ovary fibrosis in PCOS. However, RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β(1) and CTGF.

With Bupleurum smithii var. parvifolium and B. scorzonerifolium as test objects, in order to provide a theoretical basis for the introduction and domestication of B. smithii var. parvifolium, the growth and development dynamics of seedlings, biomass accumulation, the content of malonaldehyde(MDA), the activity of antioxidase such as SOD, POD, CAT and APX between them were comparatively analyzed by direct sowing culture in the open field. The results indicated that the morphological index and the biomass accumulation of B. smithii var. parvifolium such as root diameter, root length, plant height and leaf number were inferior to B. scorzonerifolium, the antioxidase SOD and POD activity of B. smithii var. parvifolium was significantly inferior to B. scorzonerifolium (<0.05), the antioxidase CAT and APX activity of B. smithii var. parvifolium was inferior to B. scorzonerifolium but the difference wasn't significant, while MDA content was superior to B. scorzonerifolium(<0.05). Thus, compared with cultivated B. scorzoneri folium, the plant growth velocity of wild B. smithii var. parvifolium was relatively slower and its resistance was relatively weaker after introduction and domestication.
