ABSTRACT
Objective To evaluate clinical efficacy on treatment of axillary hyperhidrosis by botulinum toxin type A injection and to introduce a corresponding method evolved from Minor's starch iodine test with MATLAB analysis.Methods Ten patients were involved in the study and evaluated preoperatively by both Hyperhidrosis Disease Severity Scale (HDSS) and Minor's starch iodine test with MATLAB analysis.All cases were treated with botulinum toxin type A injection dosed by 50 U on one side focally and evaluated postoperatively by both above mentioned methods with interval of 1 month and by HDSS only of 6 months.Results The clinical efficiency by the therapy evaluated by HDSS accounted for 100％ and 60％ postoperatively with intervals of 1 month and 6 months respectively.By the Minor's starch iodine test with MATLAB analysis,all patients showed no statistical difference between two matched sides preoperatively (P ＞ 0.05),while postoperatively statistical difference was observed between the treated side and the control (P＜0.05) and also between the treated group and zero control (P＜0.05).Conclusions The clinical efficacy of botulinum toxin type A injection in treatment of axillary hyperhidrosis is highlighted in short term.The evolved Minor's starch iodine test combined with MATLAB analysis serves as an alternative which facilitates operability and objectivity evaluating the therapy outcomes on hyperhidrosis.
ABSTRACT
Objective To study the effect of IZL-2003Ⅱ Immune Therapy System on lymphocyte immuno-function induced by chemotherapy in advanced non-small-cell lung cancer(NSCLC)patients.Methods 112 cases of advanced NSCLC patients were randomly divided into the two groups .The treatment group ( n=56 ) was given IZL-2003ⅡImmune Therapy System after chemotherapy for 6d as a couse and the control group ( n=56) was given chem-otherapy only.The peripheral blood routine and T lymphocyte subgroup (CD3+,CD4+, CD8+and CD4+/CD8+)activity of patients in both group were measured by flow cytometry 1 day before chemotherapy and the 8th day after chemothera-py.ResultsThere was difference between the treatment group and control group on the increasing rate of Leucocyte (P<0.05)the 8th day after treatment;After the 8th day,the expression levels of CD8+T cells was lower,but has no significant(P<0.05);The expression levels of CD3+,CD4+and the ratio of CD4+/CD8+were higher in the treatment group(P<0.05).The expression levels of CD3+T cells was lower,but has no significant(P<0.05);The expression levels of CD4+T cells and the ratio of CD 4+/CD8+were significantly lower after treatment in control group ( P<0.05);the expression levels of CD8+T cell was higher significantly in the control group (P<0.05).Conclusion IZL-2003ⅡImmune Therapy System can antagonize myelosuppression and elevated the immunologyical function of advanced NSCLC patients significantly .
ABSTRACT
The beta-secretase is one of prospective targets against Alzheimer's disease (AD). A three-dimensional quan titative structure-activity relationship (3D-QSAR) model of Hydroethylamines (HEAs) as beta-secretase inhibitors was established using Topomer CoMFA. The multiple correlation coefficient of fitting, cross validation and external validation were r2 = 0.928, q(loo)2 = 0.605 and r(pred)2 = 0.626, respectively. The 3D-QSAR model was used to search R groups from ZINC database as the source of structural fragments. As a result, a series of R groups with relatively high activity contribution was obtained to design a total of 15 new compounds, with higher activity than that of the template molecule. The molecular docking was employed to study the interaction mode between the new compounds as ligands and beta-secretase as receptors, displaying that hydrogen bond and hydrophobicity played important roles in the binding affinity between the new compounds and beta-secretase. The results showed that Topomer CoMFA and To pomer Search could be effectively used to screen and design new molecules of HEAs as beta-secretase inhibitors, and the designed compounds could provide new candidates for drug design targeting AD.

ObjectiveTo evaluate the efficacy of stereotactic body radiotherapy combined with coinstan taneous gemcitabine,and gemcitabine alone for advanced pancreatic cancer.Methods56 advanced pancreatic cancer patients were assigned into observation group,which accepted stereotactic body radiotherapy combined with coinstantaneous gemcitabine 500 mg/m2,d1,d8.Other 50 patients were assigned into the control group which only accepted gemcitabine 1 000 mg/m2,d1,d8,d15.Stereotactic body radiotherapy was delivered with a total dose of 4 000-4 500 cGy in 10 fractions.ResultsCT examinations were carried out 2 months after treatment.The response rate of the observation group and control group was 82％ and 16％ respectively,and the pain relief rate was 67％ and 17％ respectively.The time to progression of the observation group was 14 months,and was better than that of the control group(7.5 months,x2 =7.31,P =0.032).The median survival time of the observation group and control group was 15.8 months and 13.2 months,and the difference had no statistical significance(x2 =3.28,P =0.082).ConcolusionStereotactic body radiotherapy combined with gemcitabine has a better overall response rate and a pain relief rate.It can prolong the time to progression,but can't improve the overall survival.
ABSTRACT
BACKGROUND: The detection of a broad spectrum of HPV genotypes has not been used widely in cervical cancer screening due to technical difficulties and high costs. OBJECTIVES: To develop an asymmetric GP5+/6+ PCR assay and hybridization with a fluorescence polarization (FP) assay of 15 HPV genotypes. STUDY DESIGN: HPV genes in controls and samples were amplified by an asymmetric GP5+/6+ PCR. Fifteen HPV genotypic probes labeled with fluorophores hybridized with target PCR product to identify the presence of specific HPV genotypes. The HPV genotypes in samples were verified by sequence assay. RESULTS: The genotypes determined with the hybridization and FP assay were confirmed by sequence analysis when a monotypic infection was evaluated. CONCLUSION: A simple, economical and specific HPV genotyping assay has been developed that will be adequate for cervical cancer screening programs.
