Objective To assess the efficacy and safety of transurethral resection of the prostate(PKRP) and bladder tumor(PKRBT) with plasmakinetic energy. Methods 300 patients(mean age of 71.6 years;range from 52 to 91) with symptomatic BPH without suspected cancer (confirmed by IPSS,urinary flow rate,ultrasonographic estimate and PSA tests) were treated by PKRP. 37 patients with superficial transitional cell carcinoma (17 with tumors appearing at the lateral wall) were treated by PKRBT.All patients were followed up for 1～6 months postoperatively. Results For PKRP,the duration of the procedure was (48?31) min(range 13 to 98 min).No case need blood transfusion during the operation.No transurethral resection syndrom occurred.The mean catheterization time was 2 days (1 to 4 days). The peak flow rate increased from (5.2?3.9) to (19.2?4.1),(21.8?4.6),(22.3?5.7)ml/s at 1,3 and 6 months respectively. The IPSS decreased from 24.7 to 5.7, 5.4,5.0 and the QOL decreased from 5.3 to 1.7,1.8,1.2 at 1,3 and 6 months respectively.For PKRBT,the duration of the procedure was (24?13) min(range 5 to 39 min) with little bleeding.The adductor reflex was found in 5 of the 17 cases with tumor located at the lateral wall. Conclusions It is suggested that transurethral bipolar plasmakinetic resection of the prostate and bladder tumor is effective and safe. This pilot series permits a comparative study with conventional TUR system.

Objective:To investigate the rational use of antiplatelet drugs and provide references for clinical utilization. Method:The sales amount,defined daily dose(DDDS) and daily expense(DDDc) of antiplatelet drugs in senile wards of our hospital were collected and analyzed,and other kinds of drugs which had drug interaction with aspirin were monitored by the Prescription Automatic Screening System(PASS) during 2007-2008.Result:Clopidogrel Hydrogen Sulphate Tablet was No.1 of all DDDs and Alprostadil Fat Emulsiom Injection was the most expensive of all the antiplatelet drugs,and the DDDs of aspirin was lower only than that of Clopidogrel Hydrogen;moreover,there were some problems in the clinical use of aspirin.Conclusion:The antiplatelet drug utilization in the senile wards almost meets with the guidelines and develops towards the direction to use new drugs with good action and few side-effects,but needs further standardization.

BACKGROUND:Non-operation therapies are commonly used in the treatment of cervical spondylopathy. All of these therapies involve biological mechanics; especially for traction and massage of the cervical vertebrae, they have an obvious property of biological mechanics in rehabilitation of the cervical vertebrae. OBJECTIVE: To probe into the biological mechanics of different rehabilitation methods through comparing the intervention effects between traction and traction combined with massage on cervical spondylopathy.DESIGN: A case-controlled observation. SETTING: Rehabilitation Center of West China Hospital of Sichuan University. PARTICIPANTS: Among the patients who came to the Rehabilitation Center of West China Hospital of Sichuan University between October 2002 and July 2003 for the treatment of spondylopathy, totally 52 patientsmet the criteria for non-operation therapy. They participated in the experiment voluntarily and were randomly divided into 2 groups: the experimental group and the control group, with 26 patients for each. METHODS: ①The patients in the experimental group were treated by traction in combination with massage. Traction was performed once a day,30 minutes each time, 5 times as a course of treatment, and one or two courses of treatment in total. Massage was performed for 8 to 10 minutes each time, once a day, 5 times as a course of treatment, and one or two courses in total. ② The patients in the control group were treated with traction only. Cervical Spondylopathy Therapeutic Effect Rating Scale was adopted to evaluate the effects, three items were selected to set as our scoring criterion, which included clinical symptoms, physical examinations and activities of the daily life (ADL). The improvement index was figured out on the basis of the pre-treatment score and post-treatment score. The improvement index is worked out by the following equation: improvement index = (The post-treatment score-pre-treatment score) / the post-treatment score. The improvement index was evaluated by physicians after the treat ment. Effectual: Clinical symptoms and body symptoms were obviously improved; work, learning, and daily life are not affected. Effective: Clinical symptoms and body symptoms have improved , and work, learning, and the daily life are partially affected. In-effective: There was no improvement in clinical symptoms and body symptoms and showed no effect on the work ,learning, and the daily life. MAIN OUTCOME MEASURES: ① Score of the treatment of cervical spondylopathy of the patients before and after the treatment. ② Intervention effect on the patients after the treatment RESULTS: Totally 52 patients with cervical spondylopathy entered the stage of result analysis with none missing in the midway. ① Comparison of the scores of the treatment of cervical spondylopathy of the patients before and after the treatment: After the treatment, the score in the experimental group was significantly higher than that in the control group [ 16.431 ±3.212,13.147 ±3.036 ( t =4.676, P ＜ 0.01 )], and the improvement index of the patients in the experimental group was significantly higher than that in the control group [0.505±0.163,0.368±0.145 (t=3.860, P ＜ 0.01 )]. ② Comparison of the intervention effects on the patients after the treatment: The effectual rate of the experimental group was higher than that of the control group (80.8%,46.2%).CONCLUSION: The approach of traction combined with massage is superior to simple traction. Different rehabilitation approaches have different properties in biological mechanics. It has showed that the force change is important to therapeutic effectiveness on cervical spondylopathy.

Objective To investigate the expression of syndecan-1 (SDC1) in glioma cells and the effects of synde?can-1 knockdown on the proliferation and invasion of A172 cells. Methods The expression of syndecan-1 in glioma cells was analyzed using quantitative Real-time PCR and Western blotting. A172 cells were transfected with lentiviral vector carrying SDC1 shRNA to establish a stable SDC1-silencing cell line. The cell proliferation was analyzed by MTT assay. Trypan blue exclusion assay and flow cytometry, and Transwell assays were performed to measure the migration and invasion abilities, respectively. The mRNA and protein and expression levels of SDC1, Proliferation Cell Nuclear An?tigen (PCNA) and Matrix Metalloproteinase 9 (MMP-9) were detected by using qRT-PCR and Western blotting. Results The expression levels of SDC1 were significantly different in different glioma cell lines. The stable SDC1-silencing cell line was successfully established, in which the mRNA and protein expression levels of SDC1 were significantly decreased (P<0.05). SDC1 knockdown significantly reduced the cell proliferation, migration(58.40±5.24 vs. 255.8±16.09、226.5± 22.84,F=126.4,P<0.05)and invasion(61.67 ± 16.26 vs. 233.70 ± 17.24、244.30 ± 28.15,F=69.87,P<0.05)compared with either control group or blank group. SDC1 knockdown also significantly decreased the mRNA and protein expression levels of PCNA and MMP-9 (P<0.05). Conclusion:SDC1 knockdown suppresses the capacities of proliferation, invasion and migration of glioma A172 cell, implying that SDC1 may serve as a novel target in the biotherapy of glioma.
