Objective: To investigate the feasibility and operative effect of the one-stage microsurgery for clipping of bilateral posterior communicating artery aneurysms (BpcoAA). Methods: The clinical data of 28 patients with BpcoAA were analyzed retrospectively. All patients underwent craniotomy and microsurgical clipping of BPcoAA via unilateral pterional approach. The patients were followed up for 6 months to 3 years after microsurgery. The head 3 D-CTA of the patients and their general conditions were reexamined. The Glasgow outcome scale (COS) scores were used to assess the prognosis. Results: Circled digit oneGood preoperative 3D-CTA showed 28 cases with 56 aneurysms, the aneurysms were clipped completely in 24 cases, the contralateral aneurysms were not clipped completely in 3 cases, the aneurysm was not clipped completely on the approach side in 1 case, and none of the patients died. The aneurysms ruptured in 8 cases on the approach sides during the microsurgery. Circled digit twoAfter microsurgery, 7 cases had hydrocephalus, and 5 had vasospasm on the approach sides and 3 on the contralateral sides, 3 suffered pulmonary infection, and 2 had oculomotor nerve injury on the contralateral sides. Circled digit threeThe mean follow-up time of the patients was 1.7 years. The GOS scores: 5 points in 10 cases, 4 points in 7 cases, 3 points in 9 cases, and 2 points in 2 cases. There were no aneurysm recurrence and new aneurysm formation. The patients whose aneurysms were not clipped completely had no recurrence of bleeding. Conclusion: According to 3D-CTA examination, using unilateral pterional approach, aiming at the location of the optic chiasm and the contralateral aneurysm pointing, the one-stage microsurgery for clipping of BpcoAA is safe and feasible.

Objective To discuss the relationship between the diameter of portal vein and esophagogastric variceal bleeding and the severity of liver cirrhosis by CT portal venography ( CTPV). To analyze the occurence about esophagogastric variceal bleeding under in different liver cirrhosis degree. Methods 60 patients of portal hyperten-sion with liver cirrhosis and 15 healthy volunteers (controls). According to Child-Pugh classification, 60 patients were divided into Child-Pugh A,B and C groups,According to the patients whether the esophagogastric variceal bleeding or not, it was divided into two groups that esophagogastric variceal bleeding (EVB) and no EVB. All of patients underwent with 64-slice spiral CT. Image post-processing techniques such as MIP, VR, MPR and SSD were applied to measuring the diameters of portal venous system vessels and depict the portosystemic collaterals of portal venous system. Results The diameters of the right branch of portal vein and super mesenteric vein were no statisti-cal significance between bleeding group and no bleeding group. The rest parameters of portal system in EVB group are all larger than those of no EVB group(P<0.05). Age and gender in two groups had no statistic significance. All diameters of portal system in cirrhotic group were all larger than those of control group(P<0.05). In different liver function,there are differences in each groups of diameter. The bleeding rate of different groups according to he-patic function showed statistical significance(P <0.05), higher the degree of liver cirrhosis, higher the bleeding rate. Conclusion The diameters of portal system in EVB group are larger than no EVB. All diameters of portal sys-tem in cirrhotic group are all larger than those of control group. There is difference the diameter of vascular in differ-ent hepatic function. Different degree of liver cirrhosis can predict the esophagogastric variceal bleeding.

Purpose To summarize the clinical and echocardiographic characteristics of congenital quadricuspid aortic valves (QAV) so as to improve the understanding of QAV and the accuracy of preoperative diagnosis.Materials and Methods The clinical and echocardiographic data of 7 patients with QAV at the First Affiliated Hospital of Nanchang University were retrospectively studied,and the features such as the aortic valve (AV) leaf number,echo,shape,opening and closing movements,and its hemodynamics were observed and compared with surgical follow-ups.Results Five out of the 7 patients had chest tightness,chest pain,fluster,shortness of breath,and 2 others had no discomfort.The echocardiography presented that all the cases had moderate or severe aortic valve regurgitation.4 patients were diagnosed as QAV,2 patients were not diagnosed definitely,and the rest 1 was misdiagnosed.6 patients underwent aortic valve replacement and were all confirmed with QAV,among whom 2 patients were combined with infective endocarditis,and 1 patient was with aortic dilatation.All the surgical operations were successful and the patient's physical conditions were good after surgery.Conclusion Echocardiography plays an important role in diagnosis of aortic valve,but it is possible to be missed or misdiagnosed.Most QAV patients have good prognosis,but close follow-ups are needed when QAV is combined with other complex deformity or has induced secondary damages.

A method has been developed for the determination of stimulants in products of nutritional supplement. The stimulants in the samples were extracted with a solution of sodium hydroxide and then cleaned up by liquid -liquid partitioning.The extracted stimulants were analyzed by gas chromatography with HP-5capilary column and detected by the Nitrogen-Phosphorus detector (NPD). The results showed that the method had good purifying effect with high sensitivity. The operation was also simple and quick. The detection limit ranged from 5 to 40 ?g/L and the average recovery rate was 75.4%～143.1% with relative standard deviations (RSDs) ranged from 0.27% to 5.5%.

Adaptor protein ClpS is an essential regulator of prokaryotic ATP-dependent protease ClpAP, which delivers certain protein substrates with specific amino acid sequences to ClpAP for degradation. However, ClpS also functions as the inhibitor of the ClpAP-mediated protein degradation for other proteins. Here, we constructed the clpS-overexpression Mycobacterium smegmatis strain, and showed for the first time that overexpression of ClpS increased the resistance of M. smegmatis to rifampicin that is one of most widely used antibiotic drugs in treatment of tuberculosis. Using quantitative proteomic technology, we systematically analyzed effects of ClpS overexpression on changes in M. smegmatis proteome, and proposed that the increased rifampicin resistance was caused by ClpS-regulated drug sedimentation and drug metabolism. Our results indicate that the changes in degradation related proteins enhanced drug resistance and quantitative proteomic analysis is an important tool for understanding molecular mechanisms responsible for bacteria drug resistance.

In the experiment, the production of plagues by Bdellovibrio bacteria in solid medium cultivation, the reproduction of Bdellovibrio bacteria in liquid medium cultivation and the attachment of Bdellovibrio bacteria to carrier were observed, which aimed to study the effects of enrofloxacin on the growth and at-tachment ability of Bdellovibrio bacteria BDF-H16. Results indicated that in solid medium cultivation, the production of plagues by Bdellovibrio bacteria BDF-H16 was inhibited by different concentrations (2 ?g/mL, 5 ?g/mL, 10 ?g/mL, 20 ?g/mL, 50 ?g/mL) of enrofloxacin and the inhibitory effects of enrofloxacin became stronger with the increase of the concentration of enrofloxacin. Similarly, in liquid medium cultivation, the reproduction of Bdellovibrio bacteria BDF-H16 was also obviously inhibited by different concentrations ofenrofloxacin and higher concentrations of enrofloxacin such as 10 ?g/mL, 20 ?g/mL, 50 ?g/mL had stronger inhibitory effects on the reproduction of BDF-H16. However, the growth tendency of Bdellovibrio bacteria BDF-H16 was not inhibited in 10 ?g/mL enrofloxacin. Additionally, when zeolite was added, enrofloxacin had also inhibitory effects on the numbers of Bdellovibrio bacteria BDF-H16 attached to zeolite. With the increase of the concentrations of enrofloxacin, the numbers of Bdellovibrio bacteria BDF-H16 attached to zeolite became smaller and smaller. However, the attachment rate of Bdellovibrio bacteria BDF-H16 to zeo-lite became higher under 2 ?g/mL-20 ?g/mL enrofloxacin. The results above showed that enrofloxacin had inhibitory effects on the plague production and reproduction of Bdellovibrio bacteria BDF-H16, but the at-tachment ability of Bdellovibrio bacteria BDF-H16 was strengthened in liquid medium cultivation with 2 ?g/mL-20 ?g/mL enrofloxacin and zeolite, and adding zeolite helped to reduce the adverse effects of en-rofloxacin on Bdellovibrio bacteria BDF-H16.

Objective To explore the mechanism and therapeutic effects of wet dressing with 50％ magnesium sulfate ( MgSO4 ) as a part of comprehensive treatment for wound resulted from pit viper bites in children.Methods A total of 61 children with pit-viper-bitten wound enrolled from May 2009 through May 2011 were divided into two groups,namely the comprehensive treatment group (n =31 cases) and the conventional treatment group (n =30 eases). In the comprehensive treatment group,50％ magnesium sulfate wet dressing applied to the swelling parts of body in the early stage in addition to the conventional treatment and topically bandaged once a day keeping wet with spraying saline on the top of dressing.Before the treatment and on the 1st day,the 3rd day and the 5th day of treatment,the values of myocardial enzyme and the circumference of swelling parts were recorded,and the differences were analyzed by t- test.The differences in rate of wound healing in one week between two groups were analyzed by chi-square test.Results Before the treatment,there was no statistical difference in clinical features between the two groups with different modes of treatment for the viper-bitten children (P ＞ 0.05 ). During comprehensive treatment,the values of myocardial enzyme and the circumference of swelling parts decreased more markedly than those in conventional treatment group ( P ＜ 0.05 ).The rates of wound healing in one week of two groups were 80.5％ and 56.6％ respectively.Conclusions The comprehensive treatment with adjuvant of 50％ MgSO4 for the viper-bitten children can effectively reduce the tissue damage caused by venom,and the swelling as well,restoring function of body and shortening the time for wound healing and preventing complications.
