Objective To investigate the effect of intracranial aneurysm isolation combined with extra-intracranial bypass in treatment of middle cerebral artery aneurysm.Methods From January 2013 to March 2015,there were 32 patients with complex middle cerebral artery aneurysm in our hospital,who were treated by intracranial aneurysm isolation combined with extra-intracranial bypass.The clinical symptoms and image examination after surgery were retrospectively analyzed,and the hemodynamic index of middle cerebral artery before and after treat-ment was statistically analyzed.Results The postoperative clinical symptoms of 25 patients were relieved,the mRS score was 0 point.Seven patients received surgery,1 week later,the muscle force of involved side was grade 2 to 3,the mRS score was 2 to 3 point,the blood flowing smoothly in target vessel,with no original aneurysm,no new ischemic stroke or infarct.After intervention,systolic and diastolic blood flow ve-locity were faster than those before the intervention(P <0.05),blood flow resistance were lower than those before intervention(P <0.05). Conclusion The intracranial aneurysm isolation combined with extra-intracranial bypass can effectively improve the clinical symptoms of pa-tients with complex intracranial aneurysms,with high graft patency rate and reliable effect.

re To understand the developmental toxicity of aluminum and its mechanism. Methods The embryos of SD rats at the 9. 5th day after gestation were explanted and cultured in a whole-embryo culture system with exposure to AlCl3 at Al3+ concentrations of 0.6, 0.9, 1.2, 3.0, 6.0 and 9.0 ?g/ml for 48 hours. Using Brown's mor-phological scoring system, yolk sac diameter, crown-rump length, head length and embryonic dry weight were mea-sured. Results A certain dose-effect relationship (r= - 0.890? 0.973, P

Objective To establish a method to investigate micronuclei (MN) and gene mutation at the heterozygous thymidine kinase (tk) locus induced by environmental mutagens in TK6 human lymphoblastiod cells. Methods TK6 cells were used to detect cytotoxic response, MN and mutation frequency at tk locus induced by cyclophosphomide (CP) after treatment with S9 mixture for 4 h. Results Exposure to CP for 4 h decreased relative survival (RS), induced both MN and TK mutation in a concetration-dependent manner. The maximum induction of MN and TK mutations were 8.8 and 15.7 times compared with those of control. Two distinct phenotypic colonies of TK mutants were generated, namely tk-NG and tk-SG mutant colonies but mainly the latter. Conclusion CP induced both MN and TK mutation in TK6 cells. TK6 cells can be used as an in vitro assay system to assess cytogenetic damage and gene mutation at tk locus of environmental chemicals.

AIM: To study extraction process with the aid of cyclodextrin (EPAC) of Radix Salvias Miltiorrhizae. METHODS: Taking tanshinone Ⅱ_A, Danshensu, dry extract as the indexes, EPAC and water extraction process(WEP) were compared. RESULTS:The index of tanshinone Ⅱ_A of EPAC was better than WEP in extract, but there was not obvious difference in the indexes of Danshensu and dry extract. CONCLUSION:EPAC is worth researching further.

Objective To research the absorption mechanism of paeoniflorin across Caco-2 monolayer model. Methods Depending on the Caco-2 cell monolayers drug transport model to study the double transport mechanism of paeoniflorin. To explore the effect of paeoniflorin absorption by time and drug concentration, the drug concentration was determined through the use of HPLC instrument and the Papp was calcalatad. Results In the Caco-2 monolayer model, the transport of paeoniflorin form Apical (AP) to Basolateral (BL) is similar to the transport form BL to AP. Conclusion The main mechanism of the paeoniflorin intestinal absorption in the Caco-2 monolayer model is passive transference.

Objective　To explore the mechanism of male reproductive toxicity of bisphenol-A.Methods　The morphological characteristics of seminiferous tubule,vimentin filaments and p53 gene expression in sertoli's cells of adult SD rats orally exposed to 0.5% bisphenol-A were observed and analyzed by histo-chemical and immuno-histochemical methods.Results　After 2-week-exposure to 0.50% bisphenol-A,the disattachment between sertoli's cell and spermatogonia,spermatogonia arranged in disorder and displacement of spermatogonia away from the basement membrance of seminiferous tubules as well as the flocculated chromatins of nuclei in sertoli's cells and spermatogonia were observed.Fourfold increase of p53 expression in nuclei of spermatogonia and leydig's cells and the collaps of vimentin filaments in sertoli's cells were also found.Conclusion　The results suggested that the disattachment between sertoli's cells and spermatogonia,might be associated with the collaps of vimentin filaments in nuclei of sertoli's cells and the increase of p53 expres sion in nuclei of sertoli's cells and spermatogonia,which might be one of the important mechanisms of reproductive toxicity of bisphenol-A.The increase of p53 expression in nuclei of leydig's cells might predict the potential anti-androgenicity of bisphenol-A

Objective:To explore the influence factors and the characters of infant-mother attachment in Guangdong.Methods:“strange situation"essay was used to assess the characters of infant-mother attachment in 75 infants of 8 to 14 months.An self-formulated questionnaire of infants'general status and family related factors were filled by their mothers.Results:(1)Among 75 infants,65.3% were secure-type,34.6% were insecure-type which included 17.3% of indifferent-type, 13.3% of importunate-type,and 4.0% of disorganized-type;(2)The influence factors were age,approachability,relations between infants and fosterers, and the attitude consistency among family members towards infants.Conclusion:Of this investigation, most infants were secure-type.There were some influence factors involved in the characters of infant-mother attachment.

ATM: To prepare Shenfuqing Lyophilized Powder (Radix Ginsenp Rubra, Pericarpium Citri Reticulatae Viride, ect.) METHODS:Shenfuqing Lyophilized Powder was made by freeze drying. The concentration of Shenfuqing solution and the varieties and quantities of filling material were selected as well as the stability of Shenfuqing solution and powder for injection were examined primarily. RESULTS: The better prescription is 10% mannitol and 6% drug components. CONCLUSION: The quality of Shenfuqing Lyophilized Powder is more stable than that of solution for injection.

[Objective]To evaluate the operative technique and the short-term clinical results of total hip arthroplasty(THA) for developmental dysplasia of the hip(DDH) in adults. [Method]Sixty-one patients(77 hips) with DDH who received THR without cement between December 1997 and October 2006 were followed up.In this group,53 cases were female,and 8 cases were male.The average age was 31.4 years(range,17~56 years).According to the classification of Hartofilakidis,fifteen cases were type I(eighteen hips);twenty-three cases,type Il(thirty hips);and twenty-three cases,type III(twenty-nine hips).The average Harris Hip Score was 40 points(range,16~61).All of patients were exposed through the.posterolateral approach.The threaded cup with coating were put in or near the level of the true acetabulum in all of cases.Full coating stems were used in femoral side,shortening osteotomy below lesser trochanter of femur were performed in twelve cases. [Result]The mean duration of follow-up was 49 months(range,12~118 months),the average Harris Hip Score increased from 40(range,16~61) preoperatively to 91(range,82~95) at the time of the latest follow-up.All the hips acquired union of osteotomy and bone ingrowth.None of the patients had radiographic evidence of aseptic loosening of prosthesis. [Conclusion]Uncemented total hip arthroplasty for the developmental dislocation of the hip in adults can get better results significantly,although it presents greater technical difficulty.
