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.

Gastrointestinal stromal tumors (GISTs) are common mesenchymal neoplasms in the gastrointestinal tract.The results of computed tomography play important roles in the diagnosis,treatment planning and follow up of GISTs. From August 2007 to January 2012,28 patients with GISTs were admitted to the Henan Provincial People's Hospital. Sixteen tumors showed extra-luminal growth,4 showed intra-luminal growth,7 involved both intra- and extra-luminal growth,and 1 showed extra-gastrointestinal growth.After administration of contrast media,9 tumors demonstrated homogeneous enhancement,18 showed heterogeneous enhancement and 1 showed non-obvious enhancement.The enhancement of tumors in arterial and venous phase was 20 Hu higher than that in plain scan.Angiogenesis was displayed in 6 tumors,and feeding arteries were observed in 3 tumors.

Objective To investigate the serological patterns of hepatitis B, understand the prevalence of hepatitis B infection in neonates, infants and preschool children based on hospital data in Zhejiang province and provide a basis for prevention and control of local pediatric hepatitis B infection. Methods Five serological markers were detected on electrochemiluminescence analyzer Roche E601. The results of all serological markers in children with hepatitis B from 2006 to 2010 were exported from laboratory information system and 24 892 (15 810 boys and 9 082 girls) cases were selected for further analysis according to the exclusion criterion including duplicate analysis, children older than 7 years and children living out of Zhejiang province. SPSS13.0 software and EXCEL 2003 were employed for statistical analysis in this study. Results Average HBV vaccination coverage rates among 15 413 boys and 8 840 girls were 99. 16%(98. 87% -99. 45%) and 99. 17% (98. 29% -99. 53%), respectively. Seventeen serological patterns of hepatitis B were observed, and "anti-HBs(+)alone"(64. 997%) was the dominant patterns followed by "negative" (18. 231%), "anti-HBc(+)anti-HBs(+)"(9.911%) and "anti-HBe(+)antiHBc(+) anti-HBs(+)"(4.395%), and the positive rates for other patters were 0. 004% -0. 992%. There were significant difference of detection rates for "anti-HBc(+)alone" and "anti-HBe(+)anti-HBs(+)"patterns between male and female (χ2=7.143,8.123, all P＜0.01), and there were no significant difference of detection rates for the other 15 patterns between male and female (all P ＞0.05). Ninety-four HBsAg positive cases were detected, accounting for 0.38%. Totally 19 899 anti-HBs positive cases were detected, accounting for 79.94%. Totally 16 187 cases were "anti-HBs(+) alone", accounting for 81.3%of the total anti-HBs(+) cases. The group of 1-2 years and 2 day-2 week had the highest and lowest rate for anti-HBs(+)alone respectively. The ratios in three groups with different anti-HBs levels (10-100 mIU/ml,100-1000 mIU/ml and ＞ 1000 mIU/ml) in 16 178 anti-HBs(+) children were 23. 64%, 27.66% and 13. 70%, respectively. Totally 3 904 cases with anti-HBc(+) were detected, accounting for 15.68%. The highest positivity rate and lowest positivity rate were in the group of 2-4 week and 3-4 week respectively. In total 1 565 cases with negative results, the lowest negativity rate and highest negativity rate were in the group of 9-12 month (3. 25%) and 6-7 age (36. 21%) respectively. Conclusions The dominant serological patterns of hepatitis B in local young children is "anti-HBs (+) alone" and most of the anti-HBs concentrations ranged from 100 to 1000 mIU/ml, followed by "negative". The total positive rate of HBsAg is mild. The rate of hepatitis B serological patterns in children is associated with ages but independent of gender. For interpretation of serological patterns of HBV in children below 12 months (especially in 3 months) the status of their mothers' HBV infection should also be taken into consideration.

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 observe the effects of DanShen on the growth of hepatocellular carcinoma in malignant obstructive jaundice in the SD rat model. Methods The model was established by vaccination of transplanting tumour in the porta hepatis with the walker-256 hepatocarcine line, and then obstruction was caused by the infiltration and metastasis of hepatocellular carcinoma. ② The SD rats were divided into four groups: the rats treated by 0.9% NS (n=12), the rats treated by Inosine + Vitamin C (n=20), the rats treated by DanShen (n=20) and the rats treated by 5-FU(n=20). ③ The liver function, morphological changes and the expression of PCNA VEGF and ICAM-1 in carcinoma and peri-carcinoma tissues, adjacent lobe (left-internal lobe) as well as lung tissues were observed after four experimental groups were successively treated by four medicines. ④ Statistical analysis was done to the experimental results. Results ① The growth of rats treated by DanShen injection showed that liver injury caused by malignant obstructive jaundice was significantly relieved compared with liver function and pathological morphological changes in other groups(P0.05); ③ The expression of PCNA VEGF and ICAM-1 in carcinoma, peri-carcinoma adjacent lobe (left-internal lobe) tissues as well as lung tissues were significantly downgraded in groups treated by DanShen injection compared with those in groups treated with 0.9%NS and Inosine combined with Vitamine C (P0.05). Conclusion DanShen injection not only has protective effects on liver injury caused by obstructive jaundice, but the medicine can inhibit the proliferation and growth of hepatocarcinoma, interfere with the vascularization of tumors, and prevent recurrence and metastasis of hepatocarcinoma.

Objective To study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.
