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.

OBJECTIVETo explore clinical outcomes of posterior malleolar fractures with medial-extension type through posterioromedial and posteriorlateral incision.

METHODSFrom January 2008 to January 2011,25 patients with posterior malleolar fractures with medial-extension type were treated by hollow lag screw. Among them, 15 patients were treated through posteromedial incision,including 9 males and 6 females,aged from 21 to 67 years old with an average of 48.1 +/- 1.3; there were 5 cases with type A, 6 cases with type B and 4 cases with type C,according to Denis-Weber classification. Ten patients were treated by through posterior-lateral incision,including 6 males and 4 females, aged from 23 to 64 years old with an average of 46.9 +/- 1.5; there were 3 cases with type A, 5 cases with type B and 2 cases with type C,according to Denis-Weber classification. Operation time, blood loss, length of incision, times of X-ray exposure and complications of two groups were recorded and compared, Baird-Jackson effective evaluation were applied for evaluate clinical outcomes.

RESULTSAll patients were followed up from 12 to 49 months with an average of 20.6 months. There were significant differences in operation time, blood loss, times of X-ray exposure and complications between two group (P < 0.05). While there was no obvious meaning in clinical outcomes between two groups (P > 0.05).

CONCLUSIONTreating posterior malleolar fractures with medial-extension type through posteromedial approach can expose and fix fracture under direct vision, has advantages of shorter operation time, less X-ray exposure and blood loss, is a good choice of surgical approach.

Hyperlipidemia is an important risk factor of cardio-/cerebrovascular disease, and reducing lipids has become an important project for itsclinical preventing and treating. Western medicine, with its confirmative efficacy and clear mechanism, has played an irreplaceable role. Along with the development of modern medicine, integrative medicine has gradually become a growing trend in regulating blood lipids metabolism. It not only could make up the insufficient power for Chinese medicine in lowering lipids, but also could reduce adverse reactions and economic costs brought by long-term administration of Western medicine. As a modern practitioner of Chinese medicine, we should keep clear that integrative medicine regulating blood lipids metabolism does not mean a simple combination of traditional Chinese medicine and Western medicine. We should treat it guided by systematic theories. We combine disease identification and syndrome differentiation, guide lipids lowering by integrative medicine including selecting Western drugs for blood lipids lowering, Chinese medical prescriptions for syndrome typing, and effective Chinese herbs based on modern pharmacologies.

A L-histidine producing mutant was derived from Corynebacterium glutamicum HZ4221(TRA R DCP R AMT R histidase - )by means of mutagenesis with N-methy-N′-nitro- N-nitrosoguanidine(NTG).Contrast to original strain,the amount of histidine accumulation reached to a level of 5.31g/L in a medium containing 80g/Lglucose and 30g/L ammonium sulfate after cultured for 72 hours; the transketolase activity reduced to a degree of 15.7%.The utilization of the carbon sources,genetic stability,effect of metal ions were also been investigated in this paper.

0.05).Conclusion The incidence of VVC is higher in pregnant women with GDM than in pregnant women with GIGT,however, GCT,and OGTT show no statistical differences between women with VVC and those without VVC.

Objective To investigate the effects of high-affinity tyrosine kinase receptors TrkA, TrkC and the low-affinity neurotrophin receptor p75 (p75~ NTR) protein in laser-induced retinal injury. Methods The Wistar rats were anesthetized and exposed to frequency doubling Neodymium:Yttrium,aluminum garnet(ND:YAG,?=532nm) laser for 100 plus per eye, which were sacrificed on 12 hours,1,3,7,14 and 28 days after laser exposure and eyeball was taken out. We investigated retinal histology by hematoxylin and eosin staining, and the expression of TrkA, TrkC and p75~ NTR protein was studied by means of immunohistochemistry. Results Immunohistochemistry results showed a differential distribution for these three neurotrophin receptors in the laser injuried retina. TrkA was enhanced in nerve fiber layer (NFL), ganglion cell layer(GCL) and inner nuclear layer(INL) ,which is the most nuclei of the ganglion cells, proximal M?ller cell end feet and a little cells in the innermost part of the INL, its peak of up-regulation was after day 1-3, after day 28 there was sustained. Whereas TrkC and p75~ NTR expression was enhanced in the outer nuclear layer(ONL), which is distal M?ller cell processes, TrkC up-regulated after 12 hours, its peak was on day 1-3, after day 28 there was sustained, p75~ NTR up-regulated after 24 hours, its peak was on day 3, on day 14-28 there was sustained in the GCL, which is proximal M?ller cell processes. Conclusion The expression of TrkA, TrkC and p75~ NTR participated in the course of laser injuried retinal pathology.

Objective To develop a method for the determination of berberine hydrochloride,palmatine hydrochloride and jatrorrhizine hydrochloride in Yiqi Zhixue Granules. Methods The samples were extracted by ultrasonication with methanol for 30 min,and an ion pair RP-HPLC method was applied to determine three kinds of alkaloids.The column of C18 with temperature at 30 ℃ was used to separate the target components,the mobile phase consisted of the mixed solution of 0.01 mol/L sodium-heptanesulfonate solution and equal volume of 0.01 mol/L potassium dihydrogen phosphate solution(pH being adjusted at 3.1 with phosphoric acid) combined with acetonitrile(70 ∶ 30),the flow rate was 1.0 mL/min,and the detection wavelength was at 345 nm. Results Three kinds of alkaloids were separated perfectly,the average recoveries(n=6)were 100.95 %(RSD=2.10 % ) for berberine chloride,102.14 %(RSD=2.29 % ) for palmatine chloride,and 100.71 %(RSD=2.65 % ) for jatrorrhizine chloride. Conclusion The developed method is demonstrated to be simple,specific and accurate,which can be used to determine the contents of berberine chloride,palmatine chloride and jatrorrhizine chloride in Yiqi Zhixue Granula,and to control the quality of Folium Mahoniae in Yiqi Zhixue Granules.

Objective To study the connection between vascular endothelial growth factor(VEGF) and pool prognosis in nephroblastoma.Methods Serum VEGF was measured with immuneohistochemical(ELISA) methods in 35 children of nephroblastoma at preope-ration,1 week,2 weeks after surgery respectively. Simple visiting happened after surgery 4,8,16,32 weeks.The countrol group was 35 healthy children. Result Before surgery,the median VEGF in the children was (89.47?22.45) ?g/L.After surgery 1 week,2 weeks,levels in the children fell significantly to (2.75?0.31) ?g/L,(1.52?0.18) ?g/L.There was a significant difference compared with preoperation ( t =4.125 P
