Objective To study the influence of siRNA targeting survivin on chemotherapy sensitivity of HCC cells.Methods siRNA eukaryotic expression vector was generated.After the vector stablely transfected into HepG2 cells,the effects of chemotherapy drugs on HCC cells were observed.Results The recombinant plasmid Psilence(+)-survivin was successfully constructed.Survivin mRNA expression inhibition ratio reached 73% detected by RT-PCR.MTT methods detected that siRNA treated HCC cells were affected by MCC,the survival rate of HepG2,HepG2/Silence(-) cells was inhibited only at 48 h(0.505?0.015) compared to control groups untreated with MCC(0.824?0.322)(P

Medical image registration plays an important role in the research of medical image processing field. It is widely used in the areas of clinical diagnoses, treatment, quality assurance and evaluation of curative effect. This paper gives an overview on three medical image registration methods Correlation method, mutual information method, and wavelet transform method. Features of these method and their applications are reviewed.

Objective To observe the effect and safety of modified Yishen Zhuyang Huoxue Huazhuo Formula for polycystic ovarian syndrome (PCOS) in the TCM pattern of deficiency of spleen and kidney with phlegm-dampness. Methods Totally 123 cases were recruited into this study and randomized to two groups by central random approach, 64 cases in the observation group and 59 cases in the control group. Patients in the observation group were given the modified Yishen Zhuyang Huoxue Huazhuo Formula, while those in the control group were given compound cyproterone acetate tablet, for two treatment courses, three months for one course. The changes of ovarian volume and the number of follicles before and after treatment were observed. Adverse reactions were also evaluated. Results Bilateral ovarian volumes in both groups decreased after treatment (P<0.05, P<0.01), while the control group showed a significant better improvement (P<0.05). The number of follicles in the two groups decreased, but no significant difference were observed between the two groups (P>0.05). The rate of adverse reaction in the observation group was lower than the control group. Conclusion Modified Yishen Zhuyang Huoxue Huazhuo Formula is effective for PCOS patient by reducing the ovarian volume with a low incidence of side effect.

OBJECTIVE:To provide reference for the timely and accurate judgment of drug fever induced by Piperacillin sodi-um and tazobactam sodium for injection and rational drug use in the clinic. METHODS:The medication,clinical manifestations, laboratory examination results and the physician treatment of 30 inpatients with drug fever induced by Piperacillin sodium and tazo-bactam sodium for injection from Sept. 2013 to Sept. 2014 were analyzed retrospectively and statistically. RESULTS:Most of the drug fever induced by Piperacillin sodium and tazobactam sodium for injection occurred in continuous 7 to 14 d medication,and the cumulative dosages were between 1.3 to 2.7 g/kg;73.3% of the 30 patients had fever during the intravenous drip,with body temperature mainly≥38.5 ℃;the elevation of eosinophil and slightly increase of serum C-reactive protein (CRP) and blood cell sedimentation rate (ESR) could be used as observation indexes of drug fever,but the leucocyte reduce could’t be suitable;the body temperature dropped to normal within 24 to 48 hours after stopped using it. CONCLUSIONS:The drug fever induced by Piperacillin sodium and tazobactam sodium for injection has no correlation with the patients’gender or age,and no special diagnos-tic criteria. But it has certain correlation with duration of medication,cumulative days and dosages and it can be used as reference of judgment with the combination of hematological examination index. Clinicians should improve the understanding and attention about drug fever to stop using suspicious drug in time.

Objective: To correct the set-up error of patients during radiotherapy is very important for increasing treatment effective. Methods: This paper proposes a registration method based on portal images and reference images. Canny Operator was used to extract edge features. The extracted edge features were set as datum mark to calculate the maximal mutual information between the portal images and reference images. Parameters were optimized with simplex-simulated annealing optimization strategy. Results: The portal images and reference images of 29 patients with the cervix cancer and prostatic carcinoma were registrated in this paper. The results showed that the registration was precise, and the registration speed was increased remarkably. Conclusion: So this registration method can be applied for online estimation for set-up errors in clinical radiation.
