[Objective] To discuss the relative factors of re-operational effect on iatrogenic bile duct injury(IBDI)induced by laparoscopic cholecystecto-my(LC). [Method] Make analysis on the clinical data of 20 cases of LC-induced IBDI, respectively discussing the relative factors of clinical features, opera-tional opportunity and technology in the operation of IBDI. [Result] LC-induced IBDI was influenced by operational opportunity, the treatment in the past operation and operator’s level of operation for the effect. [Conclusion] The repair opportunity and treatment of LC-induced IBDI were the decisive factors influencing patients’prognosis;it’s better to find and repair timely and for the surgeon with rich experience to do the operation.

AIM To investigate the effect of clonidine on intraocular pressure(IOP) and the possible role in which ? adrenergic mechanism plays. METHODS The change on IOP was observed following clonidine administered via three different routes: (1)clonidine topically administered to eyes; (2)clonidine intracerebroventricularly injected (icv)or topically administered after yohimbine or prazosin icv; (3)microinjection of clonidine into locus coeruleus(LC). RESULTS Clonidine decreased IOP significantly, ? 2 adrenoceptor antagonist, but not ? 1 adrenoceptor antagonist, can reverse the decreasing effect on IOP caused by clonidine icv and administered topically. CONCLUSION Clonidine administered both topically or intracranially can decrease IOP;? 2 adrenoceptor in central nervous system is involved in this effect.

Objective To measure the volume of olfaction-related cortex in olfactory dysfunction patients after upper respiratory tract infections via MRI,and to analyze the differences in the volume of olfaction-related cortex.Methods Fifteen olfactory dysfunction patients after upper respiratory tract infections (patient group) and fifteen age-and gender-matched normal volunteers (control group) were enrolled in this study to undergo 1.5 Tesla MR scanning.The volumes of olfaction-related cortex,including entorhinal cortex (EC),perirhinal cortex (PRC) and insular cortex (IC),were drawn and computed with Dr.View software.Olfactory function test was performed with the Sniffin' Sticks method which consisted of three tests:odor threshold (THR),odor discrimination (DIS),odor identification (ID),and their sum score (TDI).Statistical differences in the volumetric measures of bilateral EC,PRC,and IC between patient and control group were analyzed by analysis of covariance (ANCOVA) with age and intracranial volume (ICV) as covariates.Statistical differences in the olfactory function between patient and control group were analyzed by ANCOVA with age as a covariate.Results (1) The EC volume of patient group in the left and right side were (1.5 ± 0.3),(1.6 ± 0.1) cm3,while the control group were (1.7 ± 0.2),(1.8 ± 0.3) cm3 ; The PRC volume of patient group in the left and right side were (1.9 ± 0.4),(1.9 ± 0.3) cm3,and the control group were (2.5 ± 0.8),(2.3 ± 0.7) cm3 ; The IC volume of patient group in the left and right side were (5.2 ± 0.4),(5.8 ± 0.5) cm3,and the control group were (5.8 ± 0.8),(6.7 ± 0.2) cm3.EC,PRC and IC volumes of patient group and control group were measured and the results showed that the olfaction-related cortex volume was decreased in patient group showing significant statistical difference (F =4.913,4.793,7.832,5.574,9.842,7.221,P ＜ 0.05).(2) Olfactory function test of patient group and control group was performed and the results showed that the scores of patient group were lower than that of control group,and the differences were significant (F =54.508,118.774,93.039,53.692,74.139,53.626,91.842,91.696,P ＜ 0.01).Conclusions It is feasible to measure the volumes of olfaction-related cortex with MRI,and the volumes of EC,PRC and IC decreased in olfactory dysfunction patients after upper respiratory tract infections compared with normal people.

OBJECTIVETo investigate the clinical features, surgical transcranial approaches and outcomes of giant pituitary adenomas.

METHODSA series of 112 consecutive cases of giant pituitary adenomas underwent microsurgery through transcranial approaches at People' s Liberation Army General Hospital were retrospectively analyzed. Of the 112 patients, 58 were male and 54 were female, with age ranging from 3 to 72 years(mean age 44. 3 years). There were 91 non-functioning adenomas and 21 hormone-secreting adenomas. The maximum tumor diameter varied from 4. 0 to 7. 2 cm, with mean diameter of 4. 8 cm. Unilateral subfrontal approach was chosen in 16 cases, pterional approach in 41 cases, anterior interhemispheric approach in 34 cases, transcallosal-interforniceal approach in 6 cases, transcortical- transventricular approach in 5 cases, combined approach in 6 cases and other approaches in 4 cases. Postoperative MRI and endocrine function were re-examined routinely to evaluate the therapeutic efficacy. Staged operation through transsphenoidal approach or adjuvant treatments including medical and radiation therapies were administered in patients with hormone-secreting adenomas when hormonal excess persisted after surgery and in patients with non-functioning adenomas who had postoperative MRI evidence of residual tumor.

RESULTSTotal removal of the lesion was achieved in 57 cases (50. 9%) , 26 patients (23. 2%) underwent subtotal resection, and 29 patients (25. 9%) underwent partial removal. Postoperative mortality occurred in 3 patients (2. 7%). Major surgical morbidity occurred in 38 patients (33. 9%). Vision was preserved or improved in 98 patients (87. 5%). The postsurgical follow-up period varied from 3 to 64 months (mean 19. 5 months) . Nineteen of the 21 patients with hormone-secreting adenomas were considered to be in hormonal remission, and 87. 2% of the cases were capable of normal work and life and 8 patients suffered recurrence during the followed-up period.

CONCLUSIONSSelection of appropriate transcranial approaches is the key to successful microsurgery for giant pituitary adenomas according to the morphological characteristics presented in image examinations and clinical symptoms. Staged transsphenoidal operation and/or adjuvant therapies including medical and radiation therapies offer the best chances to control the residual tumors after the maximal surgical removal of giant adenomas through transcranial approaches.
