OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.
METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.
RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.
CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.

Objective To investigate the effects of rapamycin on p-JAK2,STAT3,p-STAT3 and PCNA in ranal tissue of IgAN rats.Methods The animal models of IgA nephropathy were devided into control group,IgAN model group,losartan group and rapamycin group.The clinical efficacy of rapamycin,and its influences on the protein and mRNA expressions of STAT3,p-STAT3,p-JAK2 and PCNA were determined by western blot,RT-PCR and immunohistochemical techniques respectively.Results The protein and mRNA expressions of p-STAT3,STAT3,p-JAK2 and PCNA were significantly increased in kidney of IgAN rats(P

AIM: To observe the effects of puerarin on blood pressure(BP),serum lipid in a rat model of insulin resistance and the mechanism.METHODS: Adult SD rats were maintained on high-fat-sugar-salt diet for 12 weeks.Puerarin was administered to the rats from 9th week for 4 weeks by intramuscular injection.BP was measured at the end of 0,8th,12th week.The levels of serum glucose,serum lipid,fasting serum insulin and the levels of MDA,TNF-?,plasma rennin,angiotensinⅡ(AngⅡ) and the activity of SOD were measured and the insulin-sensitivity index was also calculated at the end of the experiment.RESULTS: High and middle dosage of puerarin significantly decreased blood pressure,reduced the levels of serum lipid and AngⅡ,and also increased insulin-sensitivity index.The levels of MDA and TNF-? were significantly decreased by high dosage of puerarin.The activity of SOD was increased significantly.CONCLUSIONS: Puerarin possesses the effects of decreasing the blood pressure and serum lipid in a rat model of insulin resistance,which may be concerned with the changes of rennin-angiotensin system,the levels of oxygen-derived free radicals and TNF-?.

?AIM: To study the association of the single nucleotide polymorphism ( SNP) rs1157699 in the calcitonin receptor-like receptor ( CRLR ) gene with primary angle closure ( PAC) in a Han Chinese population.?METHODS: All samples, involved 232 PAC cases and 306 controls, were obtained from an epidemiologic survey conducted in Funing, Jiangsu Province, China. Genotyping were carried out by TaqMan-MGB probe using the real time quantitative polymerase chain reaction system to study the relationship between SNP of rs1157699 in CRLR gene and PAC.?RESULTS: The prevalence of CRLRrs1157699 genotype was 67.4%, 30.0%, 2.6% for CC, CT, TT in cases, and 71.3%, 27.0%, 1.7% in controls respectively.There was no difference between the two groups in the distribution of genotype and allele frequencies of rs1157699 (P>0.05).?CONCLUSION:Our results do not support a significant role for rs1157699 in CRLR with PAC.
9.Clinical effect of reattachment of permanent anterior teeth with crown fracture.
West China Journal of Stomatology 2011;29(2):171-172
OBJECTIVETo compare the clinical effect between reattachment of permanent anterior teeth with crown fracture using dual-cured resin combined with dentin pin and conventional method.
METHODS49 permanent anterior teeth of 38 patients which had intact incisal edge segments were divided into two groups. In experimental group reattachment was conducted by dual-cured resin combined with dentin pin, while in control group only dual-cured resin was adopted. Cases were assessed clinically by one year's followed up.
RESULTSThe success rate was 95% in experimental group and 64% in control group after one-year's follow-up (P < 0.05).
CONCLUSIONThe clinical effect of reattachment with dual-cured resin combined dentin pin to treat anterior crown fracture is superior to conventional method.

Objective To develop kinesthetic and visual imagery questionnaires applicable to Chinese stroke survivors and evaluate their test-retest reliability,inter-rater reliability and internal consistency.Methods The English version of a kinesthetic and visual imagery questionnaire (KVIQ) was translated into Chinese using wellaccepted questionnaire translation procedures.Thirty stroke survivors were each assessed twice using two versions of the translation (the KVIQ-20 and the KVIQ-10) by two experienced raters with an interval of 7 days between the tests.The test-retest reliability,inter-rater reliability and internal consistency of the visual imagery score (visual imagery subscale),the kinesthetic imagery score (kinesthetic imagery subscale) and the total scores for the KVIQ-20 and KVIQ-10 versions were analyzed.Results The test-retest coefficients,the inter-rater reliability correlation coefficients and Cronbach's alphas for the KVIQ-20 version ranged from 0.879 to 0.945,from 0.894 to 0.936 and from 0.867 to 0.919,respectively.The corresponding measurements for the KVIQ-10 vcrsion were 0.914 to 0.953,0.852 to 0.900 and 0.827 to 0.878.Conclusion Both the KVIQ-20 and KVIQ-10 Chinese instruments have shown good testretest and inter-rater reliability and good internal consistency in assessing stroke survivors.Either is an effective tool for assessing their motor imagery ability.
