Objective To observe the efficacy of radical nephrectomy plus embolectomy for the treatment of renal cell carcinoma with renal vein or inferior vena cava involvement. Methods Clinical and pathologic data of 8 patients with renal cell carcinoma extending into renal vein or inferior vena cava were summarized.The operative essentials were introduced,and survival periods were followed up. Results A total of 8 patients underwent radical nephrectomy plus embolectomy.One patient died during the operation after embolectomy with exhausted respiration and cardiovascular function.Three patients survived for 2,4 and 22 months respectively,but all died of distal metastasis later.Four patients were alive for 2,14,25 and 47 months respectively after operations till writing of this article. Conclusions Radical nephrectomy plus embolectomy is a valuable method for the treatment of renal cell carcinoma with renal vein or inferior vena cava involvement.

Objective To evaluate the efficacy of repeated internal urethrotomy as the treatment for male urethral stricture. Methods A total of 296 patients with proved urethral stricture was treated with optical internal urethrotomy and the value of repeated internal urethrotomy has been analysed. Results Of the 296 patients internal urethrotomy has been successful in 261 (88.2%),217 patients with single operation,twice or three times with successful outcome in 32 and 12 patients respectively.35 patients (11.8%) failed with more than three times internal urethrotomy,of which 26 patients was then treated with stents and 9 required open surgery. Conclusions Internal urethrotomy is an efficacious treatment for male urethral stricture,but repeated operation is of limited value especially when the course of the disease is longer than 1 year.

Objective To analyze the present situation of technical efficiency in TCM hospitals throughout the country, discuss the influencing factors causing inefficiency and propose corresponding suggestions. Methods The technical efficiency in 60 TCM hospitals in the country was analyzed using the stochastic frontier cost model for panel data and the influencing factors causing inefficiency were discussed using the multiple stepwise regression method. Results The average technical inefficiency was 22.59% and inefficiency showed an upward trend as the areas shifted from the eastern through the middle to the western regions. Five factors, including the utility rate of beds and the proportion of health technicians among the entire hospital staff, were statistically significant so far as the effect on the increase of the overall cost was concerned. Conclusion The stochastic frontier cost model for panel data is the best method for evaluating the technical efficiency in TCM hospitals. On the basis of the above analysis, suggestions for strengthening scientific management, improving the utility rate of resources and reducing unnecessary waste are put forward.

Objective:To observe the clinical effect of regulating Conception Vessel and unblocking Governor Vessel by acupuncture combined with tuina for cerebral infarction. Methods:A total of 61 eligible cases with cerebral infarction were treated with regulating Conception Vessel and unblocking Governor Vessel by acupuncture combined with tuina, once a day, 12 d for a course. There was a 3-day interval between two courses. These cases were treated for 3 courses. Before treatment, the infarction severity was graded using neurological deficit score. The score changes and correlation between infarction severity and therapeutic efficacy were evaluated after 1, 2 and 3 courses of treatment. Results:Before treatment, the neurological deficit score was (18.65±3.28), versus (13.63±3.91), (9.53±3.22) and (5.57±3.97) respectively after 1, 2 and 3 courses of treatment. When the third course was completed, 4 cases obtained almost full recovery, 33 cases obtained marked effect, 18 cases obtained improvement and 6 cases had no effect. The total effective rate was 90.2%. Conclusion:Regulating Conception Vessel and unblocking Governor Vessel by acupuncture combined with tuina can substantially improve limb function in patients with hemiplegia due to cerebral infarction.

Objective To evaluate the efficacy and safety of α1-adrenergic blockers for treating young men with primary bladder neck obstruction (PBNO). Methods A retrospective review was done of the presenting symptoms and videourodynamic findings of 22 young men younger than 35 years with PBNO. Mean age was 28 years (range 18 to 35). The presenting symptoms were hesitancy in 21 (95%), weak stream in 17(77%), frequency in 16(73%), urgency in 8(36%) and pelvic pain in 6 (27%). Mean symptom duration was 28(3-62)months. A dose of 4 mg Doxazosion was adminis-tered for at least 6 months. International prostate symptom score(IPSS), Quality of life(QOL), uro-flowmetry, post-void residual urine and blood pressure were assessed before and 6 months after medi-cation. Improved urine flow was defined as at least 3 ml. per second increase in the maximum flow rate. Improved symptom was defined as more than a 40% decrease in IPSS. Successful treatment was defined as improved in urine flow and symptoms. Results Follow-up data were available for 21 of 22 patients. The medication period was 8.7±2.5 months and follow-up duration was 12.3±4.9 months. Mean Ⅰ-PSS decreased from 16.9±3.7 to 10.7±4.5. Mean QOL decreased from 4.3±1.2 to 2.5±1.0. Mean maximum flow rate increased from (9.8±3.5)ml to (14.9±3.6)ml. per second. Mean post-void residual urine decreased from (78.2±35.6)ml to (46.5±19.4)ml. There were significant differences(P<0.01). Treatment was successful in 14 patients (67%). Drug tolerability was good. Mean blood pressure was (110.0±7.9)/ (75.0±5.9)mm Hg and (107.0±8.7)/(72.0±7.1)mm Hg before medicine therapy and after 6 months medication(P>0.05). Conclusions Videourody-namics is the diagnostic gold standard of PBNO. In our experience α1-adrenergic blockers are clinically effective therapy and safety for PBNO and have been well tolerated in young male patients.

Complications are always likely to occur in the treatment of fractures. Once fracture-related complications occur,their management will be difficuh,resulting in a long handling process that increases physical and financial pain on the patients.Fea- turing“management of fracture-related complications”,this issue intends to draw attention from orthopaedists to the challenging task of prophylaxis and treatment of such problems in clinic.Not only non-union,malunion,heterotopic ossification,bone necrosis but also such systemic complications as deep vain thrombosis,soft tissue infection and necrosis are discussed.They involve long tubular bones,pelvic,proximal femur,tibial plateau and calcaneum.Authors introduce their experience from their clinical practice which can benefit readers a lot.It is well known that an effective prevention is the best treatment.In treatment of fractures,principles must be strictly followed and preventive measures taken throughout the whole process.Once a complication has been detected,therapy should be individualized 1o gain the best outcome.

Objective To retrospectively evaluate effects of early dynamization of interlocking intramedullary nail on union of tibial shaft fractures.Methods From January 2002 to Septemher 2004,75 patients with tibial shaft fractures were treated in our department with internal fixation using static interlocking iutramedullary nails.Early dy- namization(6 to 10 weeks postoperative)was adopted in 32 patients (the dynamic group) according to the fracture con- ditions,while the other 43 patients were treated without early dynamization (the non-dynamic group).The healing time of fractures and the rate of delayed union in both groups were documented.Results All the cases were followed up for a mean duration of 6.5 months (range,4 to 13 months).The mean healing time was 115.6 days (range,105 to 126 days) in the dynamic group and 124.5 days (range,119 to 133 days) in the non-dynamic group.The difference was statistically significant between the two groups (P＜0.05).There were two cases (6.2%) of delayed union in the dynamic group and four (9.4%) in the non-dynamic group.The difference was not significant (P＞0.05). Conclusion Early dynamization of interlocking intramedullary nail can promote union of tibial shaft fractures.

Objective To assess the outcome of internal urethrotomy for the treatment of urethral stricture. Metho ds In the past 10 years, a total of 203 patients with proved urethra l strictures were treated by optical internal urethrotomy.Follow-up studies wer e carried out for 157 patients. Results Of the 203 patie nts 194(96%) have undergone successful internal urethrotomy, 9 patients(4%) with long stricture more than 3 cm failed on repeated internal urethr otomy and required open surgery. Internal urethrotomy was carried out twice for 9 patients and thrice for 5 with successful outcome. Of the 194 patients 157 wer e followed up for 6 months to 8 years, in whom 143 have had satisfactory voiding and 14 needed intermittent dilation. Conclusions Endosc opic treatment shoud be considered as the procedure of first choice for the tr eatment of urethral strictuer, however repeated urethrotomy should be avoided.
