Objective To investigate changes of CD~+_4CD~+_ 25 regulatory T cells (CD~+_4CD~+_ 25 Treg) and forkhead/winged helix transcription factor(Foxp3) mRNA in peripheral blood mononuclear cells (PBMCs) from patients with asthma, so as to elucidate the possible roles of CD~+_4CD~+_ 25 Treg in the development of asthma. Methods The peripheral blood samples were collected from 29 healthy controls (normal control group) and 78 patients with asthma which included 30 patients in exacerbation group, 25 patients in persistent group, and 23 patients in remission group. By using flow cytometry and RT-PCR, the CD~+_4CD~+_ 25 Treg ratio and Foxp3 mRNA in PBMCs were detected. Results The CD~+_4CD~+_ 25 Treg ratio and Foxp3 mRNA in PBMCs of exacerbation and persistent group were lower than that of remission group and normal control group (P0.05). Compared with persistent group, exacerbation group had lower CD~+_4CD~+_ 25 Treg ratio and Foxp3 mRNA (P

The changes of CD4(+)CD25(+) regulatory T cells (CD4(+)CD25(+) Treg) and Foxp3 mRNA in peripheral blood mononuclear cells (PBMCs) from patients with asthma were investigated in order to elucidate the possible roles of CD4(+)CD25(+) Treg in the development of asthma. The peripheral blood samples were collected from 29 healthy controls (normal control group) and 78 patients with asthma which included 30 patients in exacerbation group, 25 patients in persistent group, and 23 patients in remission group. By using flow cytometry and RT-PCR, the CD4(+)CD25(+) Treg ratio and Foxp3 mRNA in PBMCs were detected. The CD4(+)CD25(+) Treg ratio and Foxp3 mRNA in PBMCs of exacerbation and persistent groups were lower than that of remission and normal control group (P<0.05). Although the CD4(+)CD25(+) Treg ratio and Foxp3 mRNA of remission group also lower than that of normal control group, there was no significant difference between them (P>0.05). As compared with persistent group, exacerbation group had lower CD4(+)CD25(+) Treg ratio and Foxp3 mRNA (P<0.05). It was indicated that the decrease of CD4(+)CD25(+) Treg ratio and its function in PBMCs may be responsible for pathogenesis of asthma.

Objective To investigate the efficacy and adverse effects of methotrexate(MTX) and Bacille Calmette Guerin-polysaccharide nucleic acid(BCG-PSN) in the treatment of steroid dependent asthma.Methods Sixty-eight patients with steroid dependent asthma were divided into therapy group and control group.The patients in therapy group were treated with MTX and BCG-PSN,while the control group was given only MTX.The dose of oral steroid daily,symptom scores,peak flow rates(PEF) and expiratory volume in one second(FEV1) were monitored.Results Compared with before treatment,daily steroid dosage and symptom scores of two groups significantly decreased(P0.05),while PEF and FEV1 significantly increased in therapy group(P0.05).Conclusion The combined use of MTX and BCG-PSN may be more beneficial than the single use of MTX for the treatment of steroid-dependent asthma.

Objective To compare the effects of butorphanol,midazolam and innovar on relieving appendix traction response during appendectomy. Methods Sixty-eight patients who underwent appendectomy were randomly divided into butorphanol group(n=21),midazolam group(n=23) and innovar group(n=24).Butorphanol,midazolam and innovar were intravenously administered to patients during skin incision.The appendix traction response,sedation score,heart rate(HR),mean arterial pressure(MAP) and pulse oxygen saturation(SpO2) were recorded and compared among groups.Results Compared with those before operation,there was no significant changes in HR,MAP and SpO2 during operation.The effective rates of butorphanol,midazolam and innovar in relieving appendix traction response were 95.2%,65.2% and 50.0%,respectively.Butorphanol surpassed midazolam and innovar in sedation and relieving appendix traction response(P

Objective To evaluate clinical value of ultrasonography before and after stent implantation in the patients with obstructive jaundice.Methods Ultrasonic findings before and after stent implantation in 38 patients with obstructive jaundice were analyzed respectively,and location and pathological natures of the obstruction were compared with those of stent implantation.Results Stent implantation was successfully achieved in all the cases with hilum (15/15,100%) and common bile ducts obstruction(12/12,100%),ampulla of Vater (5/6,83%) ,and duodenal nipple(1/5,20%).A success rate of stent implantation was 100%(8/8) in benign lesions,and 83.3% (25/30) in malignant ones.The total success rate was 86.8%.The significant difference was found between the obstruction location and success rate of stent implantation ( P 0.05 ).Conclusions Ultrasonography not only contributes to diagnosis of location and pathological nature of the obstruction for successful stent implantation but also explores complications early.

Objective To explore the clinical results of metacarpophalangeal(MP) intra-articular fractures treatment assisted with MP arthroscopy. Methods Five patients suffered from MP joint fractures were treated with closed reduction and K-wire fixation under the MP arthroscopy. The age of the patients was from 17 to 53 years with an average of 23.5 years. There were four males and one female. All the fractures were caused by direct trauma. The head of metacarpal bone was injured in one case while the bases of proximal phalange were involved in four cases. 2 were of simple fractures and 3 of comminuted fractures. No joint surface defects were found preoperatively. The duration from injury to surgery was from 5 days to 3 weeks. The treatment results were evaluated with respect to MP arthroscopical findings, the fracture union and the postoperative function. Results The fracture lines could be seen in 4 cases under arthroscopy except one located at the palmar aspect of metacarpal head, which was then treated with open reduction and internal fixation. During the examination with MP arthroscopy, one case each of volar plate injury and collateral ligament injury was found. The patients were followed up 3-6 months with an average of 4.8 months postoperatively. All the patients obtained fracture union with a smooth joint surface. The motion of involved MP joints achieved nearly to their normal active range in 3 cases. No pain or snapping was found during the movement of MP joints. There was also no lateral instability. Only in one case, because of the massive and comminuted fracture, the involved finger was immobilized with plaster for five weeks, the ROM of MP joint became 90? for flexion and -56? for extension at 5 months postoperatively. Conclusion It is a less invasive procedure with good results to treat MP joint fractures assisted with MP arthroscopy. It is suitable for some acute MP intra-articular fractures.

Student awareness of rehabilitation medicine theory was still weak after learning for some time. We tried to impart rehabilitation concepts and thoughts to students during the course of rehabilitation technique. Following one controlled and randomized study, the Results of treatment group was more significant than that of controls.

Purpose To study the expression of HNF-1β in different type ovarian carcinoma and to explore the diagnostic value of HNF-1β in the diagnosis of ovarian clear cell carcinoma. Methods Immunohistochemical EnVision method was used to detect the ex-pression of HNF-1βin 27 clear cell carcinomas, 35 high-grade serous carcinomas, 21 endometrioid adenocarcinoma, 10 mucious carci-nomas, 13 metastatic Krukenberg tumors, and 2 transitional carcinomas. Results All of ovarian clear cell carcinomas variably ex-pressed HNF-1β and the positive rate of HNF-1β in ovarian cleat cell carcinoma was 85. 2%. Of 21 ovarian serous carcinomas, the nuclear positive of HNF-1β was 4 and HNF-1βpositive rate was 2. 9%. There was 5 HNF-1βexpression in endometrioid adenocarci-noma and the positive rate of HNF-1β was 23. 8%. The positive rate of HNF-1β in mucious carcinoma and metastatic Krukenberg tumor was 60. 0% and 53. 8%, respectively. No HNF-1βexpression was seen in transtional cell carcinoma. The sensitivity and speci-ficity of HNF-1β in the diagnosis of ovarian clear cell carcinoma was 85. 2% and 76. 5%. Conclusions HNF-1β may be a higher sensitive marker for the diagnosis of ovarian clear cell carcinoma. The diffuse and strong positive of HNF-1βmay have higher specific for diagnosis of ovarian clear cell carcinoma.
