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.

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.

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 study the regulation of quorum sensing molecule tyrosol and farnesol on biofilm formation of Candida albicans. Methods Candida albicans biofilms of clinic isolates and standard strain SC5314 were built when quorum sensing molecule existed. And inverted microscope was used to observe the morphology of C. albicans cells. RT-PCR and MTT assay were carried out to investigate the effect of quorum sensing molecule on expression of the two genes (HTA1 and EFG1) and cytoactive. Results Tyrosol could not promote hyphae development and cytoactive of C. albicans biofilms. The expression of HTA1 of C. albicans in biofilms was up-regulated by tyrosol but EFG1 was not. The inhibitory effect of farnesol on hyphae development, cytoactive and gene expression were not changed by addition of tyrosol. Conclusion Tyrosol can make C. albicans biofilms active in early stage. But when tyrosol and farnesol were simultaneously added, the effect of tyrosol were masked by farnesol. And C. albicans cells were more sensitive to farnesol than to tyrosol.

Objective To study the clinical effect of triethanolamine cream in treatment of traumatic wounds and its effect on level of interleukin-2 (IL-2), interleukin-8 (IL-8) and tumor necrosis factor-α(TNF-α).Methods 88 patients with traumatic wounds were selected in our hospital from February 2015 to January 2016, those patients were divided into observation group and control group according to coin method.The control group was treated with alginate dressing, observation group were given triethanolamine cream for treatment.The levels of IL-2, IL-8, TNF-αand visual analogue scale(VAS) between the two groups were compared.The clinical curative effect of the two groups was evaluated.Results After treatment, the total effective rate of the observation group(90.91%) was significantly higher than the control group (68.18%).There were no significant differences in VAS scores between the two groups before treatment, 5, 10,20 days after treatment, the VAS scores of the two groups were significantly lower than before treatment (P<0.05), at 5,10,20 days after treatment, the VAS scores in the observation group were significantly lower than the control group (P<0.05).The level of IL-2 in the observation group were significantly higher than the control group, the levels of IL-8,TNF-αwere significantly lower than the control group (P<0.05).Conclusion Triethanolamine cream can increase the level of IL-2 and decrease the levels of IL-8 and TNF-αin patients with traumatic wounds, it can relieve the pain of patients and has good clinical curative effect.

Objective To analyze the long- term results of vascularized fibular graft to repair defects of long bone. Methods Nineteen patients undergone vascularized fibular graft were followed- up for 5－ 20 years(mean 10.79 years). Limb function was graded with Enneking s system, and presented as percentage of normal limb function. The changes of the vascularized fibular graft were evaluated radiographically according to the International Symposium on Limb Salvage. Results The long term results of the vascularized fibular graft varied in different types of bone defects. Nine patients with congenital pseudoarthrosis of tibia had the limb function restored in 65％ and one had nonunion of fibular graft, 3 fractures(7 times), and 5 angular deformities. Three patients with congenital radial deficiency had 62％ restoration of the limb function. All of them showed early closure of epiphyses of the grafted fibulae. Five cases with osteomyelitis and bone defects combined soft tissue deficiency had 94％ restoration of the limb function, and only one occurred fracture of fibular graft. One case with soft tissue defect and concomitant ulnar defect, ulnar nerve and median nerve injury, 67％ function of limb was recovered, and union of fibula graft was good. 100％ function of limb was recovered in 1 case with cavernoma of radius and without occurring valgus deformity of donor site. Conclusion The vascularized fibular graft is a good method for repairing long segmental defects of bone. Combined with other tissue flap, the operation can reconstruct bone defect and fulfil the cover of soft tissue. For congenital tibia pseudoarthrosis and radial deficiency, the long- term results are not so satisfactory.

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.
