Objective To evaluate surgical mangement of femoral pseudoaneurysm caused by injection of addictive drugs. Methods The clinical data of 13 cases with femoral pseudoaneurysm resulted from drugs injection were retrospectively analyzed. All cases underwent operation treatment. 1 case received aneurysmectomy and lacerative repair, and 13 cases received aneurysmctomy and vascular grafting. The grafts included autogenous saphenous vein, artificial blood vessel and so on.

Objective To study the method and effect of exposure the recurrent laryngeal nerve(RLN) in preventing the damage of RLN in thyroid surgery. Methods One thousand and ten sides total and(or) subtotal thyroidectomies were operated on 574 cases with RLN exposure in our hospital in recent 9 years. Results The RLN injury rate was 0.3% in this series.Of them, permanent RLN injury occurred in 2 cases and temporary injury in 1. Conclusions The exposure of RLN can greatly decrease the nerve injure in thyroid surgery, especially in total lobectomy. The dissection of RLN must followed the principle of RLN exposure . RLN should be dissected around the inferior thyroid artery first, if the RLN is difficult to be found,then dissecting around the thyroid cartilage, or finding the cervical vagus inside of carotid sheath to find RLN should be done.

Objective Detecting the level of IDO and KYN in ulcerative colitis (UC) patients; using ROC curve to discuss their value in the diagnosis of patients with active UC. Methods 60 cases of UC group, 18 cases of dis-ease control group and 20 cases of healthy control group were included in the study. Immunohistochemical staining methods were used to detect the expression of IDO in colonic mucosa of UC, enzyme-linked immunosorbent (ELISA) methods were used to detect the serum levels of IDO, KYN and CRP, and the value with ROC curve method was analyzed. Results ① There was a positive correlation between IDO level and IDO expression (P<0.05). There was a positive correlation between KYN level and IDO expression (P<0.05). ②The levels of IDO and KYN in UC group were higher than those of disease control group and health control group (P<0.05). ③The levels of IDO and KYN in patients with active UC were significantly higher than that in patients with catabasis UC (P<0.01), and the levels increased with severity of inflammation. ④ The levels of IDO and KYN in active UC were positively related to disease activity and CRP levels (P<0.05). ⑤The IDO,KYN and CRP area under ROC curve were 0.976, 0.856 and 0.864;best cut-off point were 53.66 U/L, 2.34 nmol/L and 1.75 mg/ml;sensitiv-ity were 90.5%, 78.65% and 100.0%; specifity were 94.4%, 83.3% and 61.1%; Youden index were 0.839 2, 0.619 0 and 0.611 1. Conclusion The levels of IDO and KYN in serum can be used as an important index to judge the severity of UC. They have important value in the diagnosis of active UC . The value of IDO is higher than KYN and CRP.

Objective To explore the association of anti-mullerian hormone(AMH)in seminal plasma and serum with sperm counts and energy for male.Methods For 215 cases of healthy male selected from our reproductive clinic,with women′s reason for infertility,seminal plasma and serum AMH were detected,as semen parameters(sperm density,living rate,vitality and malformation rate),6 items of serum sex hormone.In seminal plasma and serum AMH respectively as the dependent variable,using multiple line-ar regression model to explore its quantitative relation with semen parameters and sex hormone levels.Results 215 cases were en-rolled,aged 34.28±5.70 years,while the median of the seminal plasma AMH was 0.47,quartile 0.05-3.09 pmol/ejaculation.The median of the serum AMH was 53.07,quartile 32.32 -72.20 pmol/L.Through multiple linear regression analysis,after adjusted by age and BMI,the seminal plasma of AMH and total number of sperm,sperm concentration,dynamic motility,total sperm activi-ty,serum inhibin B were positively correlated(P <0.05);The correlation between sperm morphology and other serum sex hormone had no statistical significance(P >0.05);Serum AMH negatively correlated with serum FSH,with serum inhibin B positively(P <0.05);Seminal plasma in various parameters and other related serum sex hormone had no statistical significance(P >0.05).Conclu-sion The seminal plasma of AMH were positively correlated with sperm concentration,sperm counts,sperm vitality,with the asso-ciation for serum AMH not yet found.

Objective: To investigate the changes of serum proneurotensin (PNT) and insulin-like growth factor-1 (IGF-1) levels in patients with diabetic peripheral neuropathy (DPN) and their relationship with nerve conduction velocity (NCV) and Toronto Clinical Scoring System (TCSS), so as to observe the clinical efficacy of modified Buyang Huanwu Tang on DPN patients and its effect on the levels of PNT and IGF-1. Method: Totally 68 patients with DPN were randomly divided into treatment group and control group, with 34 cases in each group. Both groups were given mecobalamin capsules orally in addition to routine therapy of diabetes, while the treatment group was given modified Buyang Huanwu Tang orally for 4 weeks. The sensory nerve conduction velocity (SNCV) of median nerve, motor nerve conduction velocity (MNCV) of median nerve, SNCV of common peroneal nerve, MNCV of common peroneal nerve, TCSS score and serum PNT, IGF-1 levels were observed before and after treatment. Result: Before treatment, there was no significant difference in SNCV of median nerve, MNCV of median nerve, SNCV of common peroneal nerve, MNCV of common peroneal nerve, TCSS score and serum levels of PNT and IGF-1 between two groups. Serum levels of PNT and IGF-1 were positively correlated with SNCV of median nerve, MNCV of median nerve, SNCV of common peroneal nerve and MNCV of common peroneal nerve (P<0.05), and negatively correlated with TCSS score (P<0.05). Compared with those before treatment, SNCV of median nerve, MNCV of median nerve, SNCV of common peroneal nerve, MNCV of common peroneal nerve and the levels of serum PNT and IGF-1 in both groups were significantly increased (P<0.05), while TCSS scores were significantly decreased (P<0.05). Compared with control group, SNCV of median nerve, MNCV of median nerve, SNCV of common peroneal nerve, MNCV of common peroneal nerve and the levels of serum PNT and IGF-1 in treatment group were higher than those in control group (P<0.05), TCSS score was lower than that in the control group (P<0.05), and the total effective rate in treatment group was higher than that in control group (P<0.05). Conclusion: Serum PNT and IGF-1 may be involved in the occurrence and progress of DPN in patients with diabetes mellitus. Modified Buyang Huanwu Tang can increase the levels of serum PNT, IGF-1, NCV but reduce TCSS score in patients with DPN. It has a definite curative effect on DPN.
