Studies on survivin over the past several years have shown it has significant association with cancer, its encoding protein play a important role in control of mitosis and/or apoptosis and the activity of cellullar immunologic response in cancer patients. Survivin is the finding of its splice variants make it more valuble. The multi-subcellular localization of survivin is consistent with its multiple functions in cellular metabolisms and responses. The mechanisms and the subcellular localization by which these splice variants differentially affect cancer development are unclear. This review article will update the role of survivin, and its splice variants in the mitosis/cell cycle, apoptosis, tumorigenesis, chemoprevention, drug/radiation resistance, and cancer therapeutics.

Aim To study tumor suppressor gene OPCML,DAPK methylation changes during the process of CasKi cell apoptosis induced by trichosanthin, and to explore the correlation and the role between cervical cancer cell apoptosis and tumor suppressor gene methylation so as to find new demethylation drugs.Methods ① MTT was applied to assay the inhibition of TCS to CasKi cell proliferation and flow cytometry was used to analyze cervical CasKi cell apoptosis induced by trichosanthin; ② Methylation-specific PCR(MSP) technology was applied to detect cervical cancer and during cell apoptosis process OPCML and DAPK gene promoter methylation status of CpG islands.Results In CasKi cervical cancer cells,OPCML and DAPK gene promoter region showed a high degree of CpG island methylation status, by trichosanthin treatment,the growth of CasKi markedly was inhibited, and flow cytometry analysed the characteristic sub-G1 peak,OPCML and DAPK gene promoter region showed no CpG island methylation of performance.Conclusions During the process of CasKi cell apoptosis induced by trichosanthin,OPCML and DAPK gene demethylated significantly,accordingly, trichosanthin might be a new methylation inhibitor,and there might be some correlation between cell apoptosis and tumor suppressor gene methylation.And OPCML and DAPK gene methylation tests might become new clinical indicators for the early detection of cervical cancer.

Objective To discuss the effects of vitamin C in vitro,on human cancer HeLa cell multiplication and apoptosis, in order to promote vitamin C in the tumor treatment application. Methods the morphology changeof cervical cancer Hela cell was observed under the inverted microscope;the effects of vitamin e on Hela cell by MTT assay; cell cyele and weakly perishing rate was analysed rate was analysed by Flow CytoMeter;applying the agarose gelatin electricity swims to analyse weakly perishes in the process the cell gene group DNA change. Results Vitamin C hinders the HeLa cell by the density and the time dependence way to the G0/G1 period, suppresses it to grow and to induce weakly perishes. Conclusions Vitamin C may suppress the HeLa cell to grow, causes the cell to hinder to the G0/G1 period and induces cell weakly perishing.Its reason possibly was HPV E6 protein expression surrenders to restoring the function of P53 gene.

Objective To investigate the feasibility,safety and efficacy of endoscopic thyroid surgery and the traditional surgical method,in order to further promote the application of endoscopic technology in thyroid surgery.Methods 72 patients from July 2009 to July 2011 in Shaoxing City People's Hospital undergoing endoscopic surgical treatment and 36 cases treated by traditional thyroid surgery were collected,and the surgical data,recovery-conditions and patients' satisfaction were analyzed.Results Except the operation time,the observed indicators of the two laparoscopic groups were superior to those of the conventional thyroid group(P ＜ 0.05).The operation time,flap area,subcutaneous tunnel set-up time,postoperative 24 h visual analogy scale (VAS) score of the sternum group were superior to the areola path group (P ＜ 0.05).The difference of intraoperative blood loss,hospital stay,patient's satisfaction for the 2 groups had no statistical significance(P ＞0.05).Conclusions Laparoscopic surgery is superior to conventional thyroid surgery in treatment effects and patients' satisfaction.As for the surgical path,sternum path is slightly superior to the areola path.Surgeons should choose the best surgical approach and the path according to patients' specific conditions.

Objective To compare the efficacy of ureteroscopic lithotripsy ( URL) combined with occlusion devices and mini-invasive percutaneous nephrolithotomy ( MPCNL) in the treatment of upper incarcerated ureteral stones. Methods A total of 89 patients with unilateral upper ureteral calculi were enrolled from April 2011 to July 2013, 42 of which were treated with MPCNL and 47 of which were treated by rigid ureteroscopic lithotripsy combined with occlusion devices. Resuts There were no significant differences in the success rate of primary lithotripsy (97.6% vs.95.7%, χ2 =0.000, P=1.000).No marked differences were detected in the stone clearance rate (97.5% vs.95.6%, χ2 =0.000, P=1.000), complication rate (7.1% vs.8.5%, χ2 =0.000, P=1.000) and operation time [(80.2 ±11.9) min vs.(65.1 ±10.9) min, t =6.248, P=0.000] between the two groups.The hospitalization time in the URL group was (3.5 ±1.5) d, which was obviously shorter than that in the MPCNL group , in which it was (7.3 ±1.5) d(t=11.931, P=0.000). Conclusion URL combined with occlusion devices can obtain satisfactory results as well as MPCNL in the treatment of upper ureteral calculi by proper case selection and careful operation performance .

Objective To estimate the effect of bacille calmette-guerin polysaccharide nucleic acid(BCG-PSN)on skin prick test(SPT)reactions,and to assess the clinical efficacy and therapeutic mechanism of BCG-PSN combined with mizolastine,in patients with chronic idiopathic urticaria.Methods A non-randomized,openlabel clinical trial was carried out.Totally,168 patients with chronic idiopathic urticaria were divided into 2 groups to be treated with mizolastine 10 mg once a day combined with BCG-PSN injection at a dose of 2 ml every other day(experiment group,n =85)or mizolastine 10 mg once a day only(control group,n =83).All the patients underwent SPT,and were evaluated by symptom score at the baseline and after 12 weeks of treatment.Statistical analysis was performed by using the SPSS 10.0 software,t test and Chi-square test were used to analyze the intra-and inter-group differences in symptom score reducing index(SSRI)and SPT results.Results After 12-week treatment,SSRI was significandy higher in the experiment group than in the control group(0.92 ± 0.33 vs.0.74 ± 0.35,t =2.39,P ＜ 0.05).In the experiment group,50 patients were cured,28 patients received a marked response,with a total response rate of 92.0％;meanwhile,32 patients were cured and 30 patients received a marked response in the control group with a total response rate of 74.6％;there was a significant difference in the total response rate between the experiment group and control group(x2 =5.62,P ＜ 0.05).The percentage of positive SPT to Dermatophagoides pteronyssinus and Dermatophagoides farinae was 24.7％ and 17.6％ respectively at the baseline,9.4％ and 5.9％ respectively after treatment,in the experiment group,24.1％ and 16.9％ respectively at the baseline,24.1％ and 15.7％ respectively after treatment,in the control group.Significant differences were observed in the percentage of positive SPT between the control group and experiment group after treatment(x2 =5.82,P ＜0.05),but not at the baseline.A statistical decrease in the percentage of positive SPT was induced by the combined therapy with BCG-PSN and mizolastine(x2 =4.56,P＜ 0.05),but not by mizolastine alone.Conclusions BCG-PSN combined with mizolastine appears superior to mizolastine alone in the treatment of chronic idiopathic urticaria,with a decrease in the percentage of positive SPT reactions and in the sensitivity to allergens.

Objective To discuss the techniques and efficacy of arthroscopy-assisted treatment for popliteal cyst. Methods From June 2004 to January 2006, 14 patients with popliteal cyst were diagnosed and treated with arthroscopy. During the operation, the popliteal cyst was removed, and then the hernial opening was repaired by suturing the medial head of the gastrocnemius tendon. The outcomes of the operation were evaluated by using Rauschning and Lindgren Grading. Results Arthroscopic examinations showed evident pathological changes in the knee joints of the 14 patients, including 6 cases of posterior horn medial meniscus tear, 1 case of chondromalacia of patella, 2 patellofemoral malalignment, 4 osteoarthritis, and 1 discoid lateral meniscal tear. The patients were followed up for 5-18 months (mean 11 months). According to the Rauschning and Lindgren Grading, 8 patients were grade Ⅱ and 6 were grade Ⅲ before the operation. After the operation, 9 patients were grade 0, 4 were grade Ⅰ, and 1 was grade Ⅱ. There was a significant difference between the pre-and postoperative grading (Z=-4.498, P=0.000). No patient had recurrence during the follow-up. Conclusions Popliteal cyst is usually induced by knee joint disorders. It was difficult to eliminate the cyst by simple resection. Arthroscopy-assisted treatment can achieve good outcomes.

Objective To study the effects of compound rhizoma bletillae paint (CRBP) on scalded rats. Methods Rats were randomly divided into test groups (CRBP low, high dose group), CRBP-CA (CRBP without chlorhexidine acetate) group, positive control group (Jingwanhong) and negative control group (no treatment) respectively, with 10 rats in each group. The drugs were administered topically on the surface of scalded places respectively after second-degree and third-degree burn scald models in rats. The rats were bred separately. The scabbing time, decrustation time and wound healing time were recorded. Results The scabbed and the decrustation time were shorter in the test group than that in the negative control group with significant differences (P

[Objective]Through a comparitive analysis between hemiarthroplaty and dynamic hip screws in femoral intertrochanteric fracture,to discuss the differences and similaries between two groups of patients.[Method]Using the methods of retrospective review,the author collected 63 cases of femoral intertrochanteric fracture,treated by hemiarthroplasty and dynamic hip screws respectively.Followed for a minimum period of 6 months,the author compared the postoperative complications,cumulative mortality rate and loss of ambulatory grades between two groups.[Result]There was no siganificant difference in operative time and introperative bleeding and no evident distinctions showed in posteroperative general conditions.But in local symptoms,DHS group appeared the cut-out from femoral head and coax vara resulting from the collapse of medial cortex,hemiarthroplaty group emerged the pain in hip without proof of loosening and infection of prosthesis.Hip scores decreased by 8.6% in DHS group and 9.2% in hemiarthroplaty group.In the opinion of the function convalescence,there was no definition to be worth recommending between two groups.[Conclusion]To eldly patients with unstable intertrochanteric fracture,fine function should be expected equal to preoperation after operation,but the chief motive is to provide the conditions which permit the patients earlier activity.So hemiarthroplaty is a reasonable alternative to a sliding screw device to treat intertrochanteric fractures.
