Objective To compare the therapeutic effects of 3 operative options with selective high level ligation of spermatic veins, transinguinal canal and renovated Potomo's laparoscopic manage-ment of varicocele. Methods From January 1990 to November 2006, 1075 primary varicocele above grade Ⅱ patients accepted the operations, of them, 685 patients had follow up data and were recruited into this study. These patients were divided into 3 groups according to the operative methods:group A (n=369) was treated with open selective high level ligation of spermatic veins, group B (n=218) was treated with open transinguinal canal operation, and group C (n=98) was treated by renovated Polo-mo's laparoscopic management of varicocele. The complications of the 3 operative methods were com-pared, such as recurrence rate, testicular atrophy rate, scrotal edema rate and semen analysis. The therapeutic effects of these 3 methods were evaluated. Results The recurrence rates of the 3 groups were 3.3%, 7.3% and 5.1%, respectively. Group A had significantly lower recurrence rate than group B, P<0.05. The testicular atrophy rates of 3 groups were 0.5%, 17.9% and 9.2%, respec-tively. There were significant differences among the 3 groups (P<0.05). The scrotal edema rates of the 3 groups were 1.4%, 17.4% and 16.3%, respectively. Group B and C had higher risk of scrotal edema than group A, P<0.05. For patients with ages younger than 30, the improved semen quality rate in group A was higher than in group B and C. The improved semen quality rate in each group of patients younger than 30 was higher than patients with age over 30. Conclusion The open selective high level ligation of spermatic veins is the best choice in the treatment for patients with primary sper-matic varicocele.

Objective To research the effect to the semen quality of the three operation methods of superiority of highly selective varicocele high ligation,transinguinal canal and laparoseopic of renovated polomo management of varicocele.Methods 561 patients in our hospital who charged by infertility had the operation were analyzed retrospectively and were recruited with primary varicocele above grade II for this study.These patients were divided into three group according to three kinds of operation methods of varicocele :group A was treated with highly selective varicocele high ligation and had 300 patients;group B was treated with transinguinal canal operation and had 181 patients; and group C was treated by laparescopic of renovated polomo operation with 80 patients.Through the comparing of the fertility ability of the three operation methods,to evaluate the therapeutic effect of the three methods.Results The increasing rates of the quality of semen in group B was higher than other groups if patients' ages were lower than 30.The increasing rates of the quality of semen in every group was also higher if patients' ages were lower than 30.No difference was found between three groups in natural conception rate (P＞0.05).Conclusion The methods of highly selective varieecele high ligation would be a better choice in the management of patients with primary varicecele because of higher quality of semen.

This study aims at the mechanism of foveola formation in bovine trabecular bone under fatigue process and its relation with biomechanical pathogenesis of senile osteoporosis. The scanning electron microscope equipped with fatigue stage was used to observe fatigue micro injury accumulation of cancellous bone. The massive foveola formation in the laminal bone of vertical trabeculae was found in the tensile fatigue test. There existed the collagen avulsion in the foveola. The massive foveola formation was also observed in the lamina bone of the horizontal trabeculae in the compressive fatigue test. The bone collagen fibers were protracted, debound with hydroxyapatite crystal, and then avulsed under tensile and bending stresses. Finally the retraction of the avulsed collagen fibers brought on the massive formation of foveolae in lamina bone. The mechanical capacity of bone also declined greatly. We infer that the direct mineralization of avulsed collagen and foveola in lamina bone would be one of the main processes of self repair in vivo, which brings on the increase in fragility and stiffness of trabeculae of senile osteoporotic bone along with the agelong accumulation of collagen fatigue injury and foveola formation in the lamina bone.

OBJECTIVE: To study the efficacy and safety of Fuzheng Huayu Capsule (FZHY Capsule) against liver fibrosis with chronic hepatitis B. METHODS: Multicentric, randomized, double blinded and paralleled control led trial was conducted on patients (aged between 18 and 65) with liver fibrosis in chronic hepatitis B Indexes observed: (1) hepatic histological changes and HBV markers were observed at 0 and 24th week during the treatment; serological indexes (HA, LN, P-III-P, IV-C) were determined and B ultrasound examination of spleen and liver was taken at 0, 12th, 24th week; liver function (during the period of follow-up, liver function and serological indexes for liver fibrosis were evaluated) were observed at 0, 6th, 12th, 18th, 24th week; (2) indexes for safety: blood and urine routine tests, renal function and ECG were examined. RESULTS: (1) Enrollment and demographic data: There was no significant difference between the trial (110 cases) and control group (106 cases) in demographic feature, vital signs, course of illness, history for drug anaphylaxis, history of previous therapy, liver function, serological indexes for liver fibrosis, liver histological examination (99 cases for test group, 96 cases for control group), HBV markers, and renal function, etc. (2) Histological pathological examination: 93 cases of liver histological examination were taken, of these 50 cases for the trial group and 43 cases for control group which turned out to be at S mean value of 2.33 and 2.11 respectively pretreatment according to criteria for liver fibrosis staging. Post-treatment, the trial showed a significant decrease with S value of 1.80 compared to that of pretreatment; however, there was no significant improvement in control group before and after the treatment with S mean value of 2.14. There was significant difference in reversing rate (decrease at least 1 stage according to criteria for liver fibrosis staging) between the trial (52%) and control (23.3%) after liver biopsy. The trial had a rather good effect on improving inflammatory activity and was superior to control group with a marked decrease of mean value of inflammatory activity and score of inflammation (P<0.05). (3)Serological indexes for liver fibrosis: There was a significant decrease in HA, LN, P-III-P, IV-C content in test group after 12 and 24 weeks' treatment compared to that of pretreatment; the differences of HA, LN, P-III-P, IV-C between 12, 24 weeks' treatment and pretreatment were significantly greater than control group (P<0.01 or 0.05); the effectual was defined as 2 of 4 indexes lowered more than 30% of the baseline, according to this criteria, the trial was 72.7%, while control group 27.4% (P<0.01). (4)Liver function: Obvious improvement of serum Alb, ALT, AST, GGT was seen in 2 groups; compared with control group, marked improvement of GGT and Alb in the trial (P<0.05); the effective rate of serum ALT in the trial group was 72.7%, while control 59.4%. (5)No changes of significant difference between pre- and post-treatment in routine tests for blood and urine, renal function and ECG, etc. There was also no difference in the stable rate of ALT and serological indexes for liver fibrosis between the trial and control group 12 weeks after withdrawal (P<0.05). CONCLUSION: Fuzheng Huayu Capsule has good effect on alleviating liver fibrosis in chronic hepatitis B without any adverse effect and is superior to Heluo Shugan Capsule. Fuzheng Huayu Capsule is a safe and effective medicine for the treatment of liver fibrosis in chronic hepatitis B.
