Objective To explore the clinical value of video-assisted thoracoscopic mediastinal tumor resection.Methods The clinical data of 32 patients(observation group) who performed video-assisted thoracoscopic mediastinal tumor resection were retrospectively analyzed,compared them with 53 patients with mediastinal tumor who underwent traditional thoracotomy (control group).The clinical outcomes including operation time,intraoperative blood loss,chest drainage duration,postoperative hospital stay,postoperative complication and postoperative analgesia drug application were compared between two groups.Results No perioperative death was observed in two groups.There were no statistical difference in operation time between two groups [(121.9 ± 41.2) min vs.(141.7 ± 35.2) min] (P ＞ 0.05).The observation group was significantly better in the intraoperative blood loss [(116.0 ±53.2) ml],chest drainage duration [(5.2 ± 1.2) d],postoperative hospital stay [(8.5 ± 1.3) d],postoperative analgesia drug application [(0.8 ± 0.7) times],postoperative comolication (3 cases),than those of the control group [(147.2 ± 45.2) ml,(6.8 ± 2.2) d,(11.2 ± 2.4) d,(2.1 ± 0.9) times,15 cases].There were statistical differences between two groups (P ＜0.05).Conclusion Complete video-assisted thoracoscopic mediastinal tumor resection is a valuable way in the treatment of mediastinal tumor,rapidly recovery and less postoperative complication.

This paper explains the research status of chemotherapy sensitivity test in three aspects of history of development, specific methods and clinical application. Chemotherapy sensitivity test is an important way to achieve individual treatment of cancer, after more than 60 years, there are two major categories(in vivo method and in vitro method) of more than 10 kinds of methods. The basic steps of sensitivity test inelude culture of primary tumor cells, chemotherapy drugs mixed, the reaction mixture, observing the results of detection and analysis of indicators. This paper focuses on basic principles, main steps and characteristics of six methods, such as the renal capsule of nude mice model of human cancer, the difference between staining cell, tetrazolium salt colorimetric, adenosine triphosphate based bioluminescence tumor chemosensitivity assay, collagen gel embedded culture method and targeting molecule sensitivity assay. Through the results of several clinical trials, it can be seen that chemotherapy under the guidance of drug sensitivity test significantly improved more than experience chemotherapy in efficient rate, median progression-free survival time, survival time, clinical complete remission rate, pathological complete remission rate, etc.

Objective To observe the bone mineral density(BMD)in type 2 diabetic women and discuss the methods for evaluation of BMD.Methods BMD was measured by dual-energy X-ray absorptiometry(DEXA)at skeletal regions of supine and lateral spine,left femur neck and left hip in 484 type 2 diabetic women and 868 healthy women.The relation of BMD of healthy women in skeletal regions with age changes was found to fit a cubic regression model.Results The peak BMD of lateral spine and hip appeared at 25-34 and 35-44 years old respectively.BMD in diabetic women was not different from age-matched healthy women.The BMD values of the different age stages in diabetic women showed no difference(P>0.05)as compared with healthy women,and decreased with the age increase.The numbers of damaged bone sites were increased with the age increase.The BMD difference values between peak value and values of different age stages showed no difference between diabetic and healthy women groups(P>0.05).Conclusion The changes of BMD in type 2 diabetic women show no difference from age-matched healthy women.And in both diabetic and healthy women,BMD decreases with age increasing.

OBJECTIVE:To study the cost-effectiveness of4dose regimens in treating chronic prostatitis/chronic pelvic cavity pain syndrome(CP/CPPS).METHODS:A total of140patients with CP/CPPS were randomly divided into4groups:Baiyanjing tablets and tamsulosin hydrochloride modified release capsules were administered for Group A;minocycline micro pills and alfuzosin retard tablets for Group B;rexithromycin tablets and doxazosin mesylate controlled release tablets for Group C;and levofloxacin tablets and terazosin tablets for Group D.The cost-effectiveness analysis was performed using pharma?coeconomics.RESULTS:The costs for the Group A,B,C and D were268.8yuan,641.8yuan,660.8yuan and666.4yuan,respectively.The effective rates were71.4%,91.4%,88.6%and91.4%,respectively.The cost-effectiveness ratios were3.76,7.02,7.46and7.29,respectively.The incremental cost-effectiveness ratios of Group B,C and D were18.65,22.79and19.88,respectively as against Group A.CONCLUSION:The treatment cost of CP/CPPS was composed of2parts:an?tibiotics? 1 -receptor blockers.Doctors should make an optimum choice based on patients'previous medication,economic status and physical condition,etc.

Objective: To observe the effect of tripterygium polyglycosid(TP,雷公藤) on airway inflammation and remodeling in rats with asthma.Methods: Forty rats were randomly divided evenly into negative control group,positive control group,normal dose TP group(TPⅠ group) and small dose TP group(TPⅡgroup).The experimental model was induced by ovalbumin sensitization.Number of cells in bronchoalveolar lavage fluid(BALF) was observed by immunocytochemical staining.The expressions of nuclear factor-?B(NF-?B),matrix metalloproteinases-9(MMP-9) and tissue of inhibitor of metalloproteinases-1(TIMP-1) were detected by immunohistochemistry method.Results: Compared with the negative control group,the counts of lymphocyte,neutrophilic leukocyte,macrophage and eosinocyte in BALF were elevated significantly,positive cell percentages of NF-?B, MMP-9 and TIMP-1 in lung tissues increased greatly in positive control group,the differences being significant(all P

Metastasis is one of the main complaints of nasopharyngeal carcinoma. After radiotherapy and chemotherapy, residual and recurrent lymph nodes in the neck are still partially seen. Neck dissection is an important salvage treatment to improve survival and life quality. The present review summarizes the distribution of residual and recurrent lymph nodes, the applications of different salvage surgeries and outcomes.

ZJ-XD-I multifunctional internal sterilization machine for medical instrumentation is applied in medical instrumentations with circulatory loop such as anesthetic machine and respirator. The machine can generate ozone and hydrogen peroxide, and then the two gases are mixed and introduced into the internal loop to eliminate adnexed hydrogen peroxide such as the virus and germ, and thus the nosocomial infection due to repeated uses of medical instrumentations. The machine is composed of the gas compression component, atomization unit, gas extraction component, control circuit and the filtrating unit.
