Objective To investigate the curative effect of DrafⅠtype,Ⅱa/b-type frontal sinus drainage used on 42 patients(75 sides)with prosopantritis.Methods A summary analysis of 42 patients(75 sides)with prosopantritis who lined DrafⅠtype,Ⅱa/b-type frontal sinus drainage according to dissect characteristics during January 2011 to October 2012.Results CT of the 42 patients shows that there are 75 sides with prosopantritis,Based on the analysis of anatomical features performed DrafⅠtype,Ⅱa/b-type frontal sinus drainage to these patients,efficiency was 82.67%.Follow-up in half a year,restenosis and atresia again of 21 sides frontal sinus ostium was found.Conclusion Draf drainage has a good curative effect with small creation,few bleed and few recur-rence in chronic prosopantritis.

Objective To investigate the curative effect of Suhuangzhike capsules and Desloratadine Citrate Disodium used in chronicity allergic pharyngits .Methods Branched 147 patients into two sets ,the observation group with 85 patients treated with Suhuangzhike capsules and Desloratadine Citrate Disodium ,the control group with 62 pa-tients treated with Desloratadine Citrate Disodium only .Results The total effective rate of the observation group was 97.6%.The total effective rate of the control group was 75.8%,with statistical significance(χ2 =14.25,P<0.05). Follow up in 6 ~8 weeks,relapse rate of the observation group was 14.1%,relapse rate of the control group was 37.1%,with statistical significance(χ2 =10.53,P<0.05).Conclusion Suhuangzhike capsules and Desloratadine Citrate Disodium has good curative effect used in chronicity allergic pharyngits ,which can be decreased relapse .

With the development of magnetic resonance (MR) technology, the concern is focused on molecular and physiological imaging besides structural information. Ultra high field MR scanner shows great superiority. 3. 0-T MR scanners provide almost two-fold signal-to-noise ratio (SNR) compared with a standard 1. 5-T MR scanner. The higher baseline SNR can be converted into a variety of alternative benefits. There are still some other changes brought about by 3. 0-T, such as higher sensitivity to motion, susceptibility effect, more difference in resonant frequency among different metabolites, and so on. These features may be a double-edged sword in structural and functional imaging. But with the ceaseless progress of the technology and gains in experience, 3. 0-T systems will provide more information and show more advantages.

OBJECTIVE: To review the molecular structure and pharmacological characteristics of DPP-4 inhibitors. METHODS: based on the research literatures in recent years, reviewed the history and development of incretin in diabetes management, especially the R & D process and the molecular structure, pharmacodynamic / pharmacokinetic (PK/PD) and clinical efficacy of DPP-4 inhibitors. RESULTS and CONCLUSION: DPP-4 inhibitors have many advantages and good future in diabetes care.

OBJECTIVE: To establish a highly effective HPLC method for analyzing 1-chlorine-2,4-dinitrobenzene (CDNB), and to determine the activity of GST enzyme in rat liver microsomes (RLM) by use of CDNB as probe and study its enzyme kinetics. METHODS: Welch Materials Ultimate™ XB C18 column (4.6 mm × 250 mm, 5 μm) was used, the mobile phase was acetonitrile-water(7:3), the flow rate was 0.8 mL · min-1, and the detection wavelength was 238 nm. CDNB was incubated with 0.02 mg · mL-1 protein in RLM at 37°C for 7 min and the reaction was terminated by cool acetonitrile. The reaction solution was centrifugated and the supernatant was filtered and analyzed by HPLC. The Vmax, Km and CLint were calculated by Sigma Plot. RESULTS: The retention time of CDNB was about 6 min without any interference. The lowest detection limit of CDNB was 1.0 μmol · L-1, and the calibration curve was linear from 2.5 to 100.0 μmol · L-1. The intra-day and inter-day relative standard deviations were less than 10% respectively. The method recoveries ranged from 99.38% to 108%. The reaction catalyzed by GST was terminated by acetonitrile and the incubation time was 7 min. The kinetic parameters, Vmax, Km, and CLint were 85.45 nmol · min-1 · (mg protein)-1, 15.09 μmol · L-1, and 5.73 mL · min-1 · (mg protein)-1, respectively. CONCLUSION: This method is reliable and the results can ac-curatelly indicate GST enzyme activity, which can be used for the kinetics study of GST in RLM.

Objective To explore the diagnosis,treatment and pathology of malignant brain tumor in children.Methods The clinical data of 61 children with malignant brain tumor were reviewed,including their age distribution,diagnosis,operation route(according to the position of the brain tumors),chemotherapy [using bischloro-nitrosourea(BCNU),teniposide(VM-26) and temozolomide]and radiotherapy (part and whole brain irradiation,three diamensions conformal therapy,gamma knife and X-kinfe).Results Of 61 cases,which including 37 boys and 24 girls whose mean age was 11.3 years,24 cases were supratentorial tumors and 37 cases were infratentorial.Forty-five tumors received total or subtotal recession,10 cases with major recession,and 6 cases with partial recession.After operation,39 cases (63.9%) received radiotherapy,and 29 cases (47.5%) with chemotherapy.Follow-up of 49 cases were achieved,in which 22 cases died and 27 cases survived.Conclusions Surgical removal is still the chief treatment for malignant brain tumor in children.The exairesis profect should be formulated according to the specificity of each case.Radiotherapy methods should be related to post-operational images(CT or MRI).And it was different from the brain tumors in adult.It is good to prolong survival duration for some chosen cases with optimal chemotherapy.

0.05).In the Laparoscopic Group ureterovaginal fistula occurred in 1 case,while in the Open Group there were 1 case of bladder injury and 6 cases of fatty dissolution beneath the incision.No statistical difference was observed in complication rate between the two groups(?2=3.255;P=0.071).Conclusions Total laparoscopic hysterectomy is a safe and effective operation.Compared with open surgery,it offers less invasion,less interference to the abdominal organs,and quicker postoperative recovery.
