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 investigate the effect of tetramethylpyrazine injection on serum ion and β2-GPI/ox-LDL in patients with IgA nephropathy.Methods 58 IgA nephropathy patients were randomly divided into two gorups with 29 cases in each group.The control group were treated by benazepril and conventional treatment of dipyridamole, the experiment group were treated on the basis of the control group with tetramethylpyrazine injection.10 days of 1 courses, 2 courses of treatment.The serum ion,β2-GPI/ox-LDL and renal function related indexes were tested.Results Compared with before treatment, the serum inorganic phosphorus,β2-GPI/ox-LDL, Scr, BUN, CysC levels and 24 h urinary protein quantitation were lower( P<0.05), the blood calcium level were higher(P<0.05).Compared with the control group, the serum inorganic phosphorus,β2-GPI/ox-LDL, Scr, BUN, CysC levels and 24 h urinary protein quantitation were lower(P<0.05), the blood calcium level were higher(P<0.05), the clinical effect were higher (P<0.05).Conclusion Tetramethylpyrazine injection can effectively decrease the serum phosphorus, β2-GPI/ox-LDL, SCR, BUN, CysC levels and urinary protein amount of patients with IgA nephropathy, elevate blood calcium levels, significantly improve renal function and with less adverse reactions.

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.

Antheraea pernyi nucleopolyhedrovirus (ApNPV) PstI-B and C fragments were cloned and sequenced. ApNPV PstI-B was 7406 bp long, contained seven open reading frames (orfs)/genes, including p87, he65, pnk/pnl, odv-ec43 and Orgyia pseudotsugata multicapsid nucleopolyhedrovirus (OpMNPV) orf107,orf108 homologue on either strands of genomic DNA. ApNPV PstI-C was 6663 bp long, contained eleven orfs/genes, including pk-1, orf1629, polh, lef-2, ptp-2, ctl-1, ptp-1 and OpMNPV orf5, orf7, orf8, orf1 1 homologue on either strands of genomic DNA. Among the eighteen baculovirus genes identification, he65 and orf1629 were two diverse genes, while polh and lef-2 were two conserved genes. ApNPV was the third baculovirus found to contain pnk/pnl gene, the fourth baculovirus found to contain both ptp-1 and ptp-2 gene.

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 measure the macular function of the fellow eye in patients with unilateral retinal vein occlusion (RVO).Methods A total of 24 cases of unilateral RVO were diagnosed by fundus fluorescein angiography (FFA),and multifocal ERG (mfERG) was recorded by RETI scan.The mfERG data of 24 fellow eyes of those RVO patients,and 18 normal control eyes were analyzed and compared.The parameters included the amplitude density,latency of the P1 and N1 wave in 6 concentric circles and 4quadrants of the mfERG graphics.Results The amplitude densities of P1 and N1 wave in first and second concentric circles of RVO fellow eyes were significantly lower than normal eyes (t=4.520,2.147;P＜0.05).There was no significant difference (P＞0.05) of P1/N1 latency in any concentric circles or quadrants between RVO fellow eyes and normal eyes.Conclusion The central fovea of the RVO fellow eyes was functionally impaired.
