Objective To investigate the prevention and treatment strategy of bile duct injury (BDI) in laparoscopic cholecystectomy (LC). Methods Latest progress was reviewed based on recent documents and the experience on BDI in LC in our department. Results With the popularity of LC, BDI in LC is increasing. The reasons include illegibility and variability of local anatomy in gallbladder trigone,injury caused by galvanothermy, as well as operator’s over confidence. In order to prevent BDI, we should apply more blunt dissection, not to use electrocogulation if possible and to study local anatomy and its variance clearly. The common bile duct and common hepatic duct should be clearly identified. Intraoperative cholangiography, laparoscopic ultrasonography and hepatobiliary scintigraphy are selections as necessary.The treatment of BDI depends on the type of BDI and its site and local condition.The treatment includes end to end anastomosis, repairing the defect, choledochoduodenostomy, Roux en Y choledochojejunostomy and so on. T tube should be maintained in place for more than half a year after operation.Conclusion The key to improve the prognosis of BDI is prevention and treatment in proper time and in correct way.

Objective To investigate the correlation of intima-media thickness (IMT) of the lower peripheral arteries and maximal shear rate (SR) in diabetic (DM) patients and to analyze the related risk factors.Methods A total of 84 diabetic patients and 46 controls were recruited in the study.Color Doppler ultrasonography technique was applied to observe the IMT,diameter(D) and hemodynamics of the lower peripheral arteries and the comparison with biochemical parameters was carried out in order to reveal their correlation to the pathological changes of vascular in DM patients.ResultsIn DM group,the SR was lower than that in control group (P＜0.05).The risk factors related to the lower peripheral arteries of DM patients also were significant difference to that of control group (P＜0.05).Conclusion The decrease of SR in diabetes patients can cause the thicker IMT,which is one of the important factors leading to atherosclerosis and is correlated to various risk factors for metabolic syndrome.

The vast majority of traumatic cranial nerve injuries are associated with compression of fragment fracture, and microsurgery outside the epidural can be used for most of the cases. Therefore, early and accurate diagnosis of cranial nerve injury is especially important. As the cranial nerves go out of the cranial cavity through the holes and cracks of the skull base, and there are a number of special structures through which cranial nerve goes into the human skull, and they include the optic canal, superior orbital fissure, facial nerve canal, jugular foramen and so on. Most traumatic cranial nerve injuries are associated with these structures; however, the common imaging examination is very difficult for these structures due to their deep location. To further study the imaging diagnosis of cranial nerve injury associated with traumatic brain injury, this paper reviews the radiological technology for examination of the special positions in the skull.

Objective To illustrate a method of lifting the upper-lip to alleviate the aging face,and to evaluate its effects and risks.Methods In the past two years,53 cases of overlong upper-lip were performed with this procedure.The recovery periods,lifted effects,side effects and the total satisfactions were evaluated.Results As for recovery periods,edema roughly reduced in 6-20 months,reddish scar faded in 1-11 months,expression restored in 2-8 months,and numbness disap peared from 4 to over 18 months.The lifted effects showed that 37 cases (78.7％) were satisfactory,7 cases (14.9％) of the lifting was not enough and still complained a long upper-lip,2 cases (4.2％) was ineffective,and 1 case (2.1 ％) considered an excessive lifting.The long term follow-up showed that 3 cases (6.4％) had obvious scar (visible at a distance of more than 1 m),14 cases (29.8％) had depression of columella/base of nostril alar or with increased exposure of nostril,3 cases (6.4 ％) had expansion or morphological changes of alar,6 cases (12.8％) had increased thickness of the upper lip and prominent vermilion tubercle,1 case (2.1％) had changes of expression,1 case (2.1％) had asymmetry,1 case (2.1％) had arching sagging,and 35 cases (74.5％) had numbness or insensitivity of upper-lip.Overall results showed very satisfied in 29 cases (61.7％),satisfied in 15 cases (31.9 ％) and dissatisfied in 3 cases (6.4 ％).Conclusions The technique for upper-lip lifting displays a significant effect with few complication.It is recommended for further clinical application.

OBJECTIVE To investigate the applicability of 3DMIA software to upper airway modeling in children with obstructive sleep apnea hypopnea syndrome (OSAHS). METHODS A total of 30 children diagnosed with OSAHS by polysomnography were included in this study. Data regarding upper airway structure were collected via spiral CT while sleeping and awake, from which a three-dimensional model of the upper respiratory tract from the nasopharynx to the supraglottic region using 3DMIA software was constructed. The upper airway volume and airway minimum cross-sectional area were measured employing software algorithms. RESULTS The upper airway volume and airway minimum cross-sectional area of the 30 children during sleep were significantly less than those while awake (P<0.01). CONCLUSION 3DMIA software modeling and software algorithm measurement are more objective than traditional radiology (e.g. Fujioka) with respect to evaluation of the extent of the upper airway narrowing in OSAHS children, and has good applicability to study upper airway morphology and function in children with OSAHS.

Objective To evaluate the effects of consolidation chemotherapy on postponing the relapse in patients with advanced epithelial ovarian carcinoma. Methods 44 patients with advanced epithelial ovarian carcinoma treated in our hospital from March 2000 to April 2004 were enrolled. Clinical complete remission was achieved after standard treatments in all these patients, and they were randomly assigned into consolidation group and control group. Relapse rate and Disease-free Survival were analyzed. Results 22 patients were assigned to consolidation group, and 22 patients as control group. The latest follow up examination was done in July 2005. Relapse rate was 45.5% in consolidation group, and 59.1% in control group (P=0.365). Mean relapse time in consolidation group was 25.3?9.3 months, and was 16.9?6.7 months in control group (P=0.019). Mean Disease-free Survival was 31.9?14.8 months in consolidation group, and was 22.7?12.9 months, in control group (P=0.033). Kaplan-Meier Survival Analysis showed no significant difference P=0.22. Conclusion Consolidation chemotherapy may postpone tumor relapse and prolong Disease-free survival in patients with clinical complete remission advanced epithelial ovarian carcinoma. While it hasn′t been proved but the results in present study did not prove that consolidation chemotherapy could lower relapse rate or elevate survival rate. Further study is needed to achieve better results.
