BACKGROUND: Intravascular stent implantation is one of the main methods for intra-extracranial artery stenosis. The safety and efficacy of stent implantation has been elevated, and symptoms or ischemic advert events with artery stenosis has been reduced. However, risks of thrombosis, cerebralhemorrhage, restenosis, and hyperperfusion still existed. OBJECTIVE: To investigate the influence of atorvastatin on ischemic adverse events following cerebral middle artery stent implantation.METHODS: Twenty-four patients received cerebral middle artery stent implantation were randomly divided into 2 groups. In the treatment group, patients were received atorvastatin 40 mg + plavix 75 mg + aspirin enteric-coated tablet 300 mg, once per day; in the control group, patients were received plavix 75 mg + aspirin enteric-coated tablet 300 rag, once per day. Ischemic adverse events, such as in-stent restenosis, transient ischemic attack, cerebral infarction, or re-interventional therapy were observed by transcranial Doppler, digital subtraction angiography, nuclear magnetic resonance imaging, diffusion weighted imaging, blood lipid level and C-reactive protein level examinations prior to and at months 1, 3, 6 and 12 after stent implantation.RESULTS AND CONCLUSION: Compared with the control group, the levels of blood lipid and C-reactive protein were obviously decreased at months 1, 3, 6 and 12 after treatment (P<0.05, P<0.01 ), with dramatically declined ischemic adverse events (P<0.05, P<0.01 ). Compared with before operation, the levels of blood lipid and C-reactive protein were decreased after operation in the treatment group (P<0.05, P<0.01). No server adverse events occurred in patients treated by atorvastatin, which showed 40 mg was safe for patients. The results revealed that atorvastatin combined with antiplatelet therapy can prevent ischemic adverse events following cerebral middle artery stent implantation.

Objective To explore a new project-integrated teaching method and evaluate its effect in the course of optometry special examination techniques. Methods Class Three of Optometry 2011 was chosen as experimental group and used the new project integrated teaching method while Class Four was chosen as control group and used traditional teaching method , both class having 30 students. After the end of the course the students of both class were assessed the theoretical knowledge and operating skills of the same standard. The self-designed questionnaire was used to investigate stu-dents' self evaluation of the teaching effect. After students of both groups practiced in the same depart-ment of ophthalmology optometry clinic special inspection post for half a year, teachers' evaluation of the students' training performance was collected. Final examination scores, experimental examination scores and the teachers' evaluation scores of the two groups were compared by t-test respectively and the self-assessment results of the students of both groups were compared by chi-square test. Results The final examination and experimental examination scores of the experimental group were both higher than those of the control group significantly(P=0.001,0.002 respectively). The experimental group students had a significantly better self-assessment than the control group in learning interest ( P=0.007), understanding(P=0.046), self-learning ability(P=0.000), summary ability(P=0.009), ana-lytical ability(P=0.000) and innovation ability(P=0.000). The clinical teachers' evaluations of the ex-perimental group were better than the control group. The differences were statistically significant in standardization of practice, application ability, examination report reading ability and case analytical ability(P=0.000). Conclusion The project-integrated teaching method can help to improve the students' leaning motivation and cultivate students' autonomous learning ability and comprehensive analysis capa-bility and so on, which is helpful to reaching a good teaching effect and ensuring the teaching quality.

Objective To investigate the effect of radix paeoniae rubra (RPR) on expressions of p38MAPK, NF-κB and iNOS in ltpopolysaccharide (LPS)-induced acute lung injury (ALI) and explore its protective mechanism. Methods Forty Wistar rats with ALI were divided randomly into five groups: saline control group (Group A) , LPS group (Group B), RPR for treatment group (Group C), RPR for prevention group (Group D) and SB203580 group (Group E). The effects of RPR on protein content and the ratio of neutrophiles in bronchoalveolar lavage fluid (BALF), contents of malondidehyde (MDA) and serum NO in lung tissue were observed. Arterial blood was collected for blood gas analysis. Expressions of p38MAPK, NF-κB and iNOS in rat lung tissues were detected. Results Compared with Group A, expressions of p38MAPK, NF-κB and iNOS were significantly increased (P <0.01 orP< 0.05) , the protein content and the ratio of neutrophiles in BALF, contents of MDA and serum NO were significantly higher (P<0.01 or P<0.05) in Groups B, C, D and E. There was a significant decrease in the level of arterial bicarbonate and partial pressure of oxygen in Groups B, C, D and E (P<0.01 or P<0.05). Compared with Group B, the expressions of p38MAPK, NF-κB and iNOS were significantly lower, and the protein content and the ratio of neutrophiles in BALF, contents of MDA and serum NO were significantly decreased, while the levels of arterial bicarbonate and partial pressure of oxygen were significantly higher in Groups C, D and E (P<0.05 or P<0.01). Compared with Group B, the lunginjury of Groups C, D and E was significantly alleviated, while there was no statistical difference among Groups C, D and E in the indices of lung injury. Conclusion Protective effect of RPR on LPS-induced ALI is closely related to the inhibited expressions of p38MAPK, NF-κB and iNOS.

Objective To explore the genetic association of C1GALT1 gene polymorphisms with susceptibility and prognosis of IgA nephropathy (IgAN) on Uyghur population in Xinjiang Uyghur Autonomous Region.Methods Ninety Uighur patients with IgAN and ninety geographically and age matched healthy controls were recruited.Peripheral blood was collected from recruited individuals for DNA extracting.After amplified by polymerase chain reaction (PCR),genotyping of the four single nucleotide polymorphisms (SNPs) in C1GALT1 gene,which were rs9639031,rs5882115,rs1008898,-527A/G,were detected by direct sequencing analysis.Differences of allele and genotype frequency were analyzed between IgAN and healthy controls.Moreover,the association between these SNPs and the risk and progress in IgAN patients were further analyzed.Results (1) The I allele frequency of rs5882115 in C1GALT1 gene was significantly higher in IgAN than that in healthy controls （x2 =7.788,P =0.015),no difference in allele frequencies of rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Under the dominant mode,the DI+ Ⅱ genotype frequencies of rs5882115 was significantly higher in IgAN than that in healthy controls (x2 =8.563,P =0.009),no difference in genotype frequencies of rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Under the hidden mode,no difference in genotype frequencies of rs5882115,rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Logistic single factor regression analysis showed that the risk to IgAN of whom carry I allele of rs5882115 was 2.469 times than the D allele (OR =2.469),and the risk to IgAN of whom carry DI+ Ⅱ genotype was also higher (OR =2.852).(3) No association was found between these SNPs in C1GALT1 gene and serum creatinine in IgAN.Conclusion Association between rs5882115 in C1GALT1 gene and Uighur IgAN susceptibility suggests that there may be variants in C1GALT1 gene or its linked genetic region,which needs further exploration.
