Objective To discuss the effect of the shape of mandibular arch on uprightness distortion ratio in computed orthopantomography.Methods 20 specimens of adult head with different shape of mandibular arch were selected.The computed orthopantomography was performed after the markers were inserted in the marking points of mandible,the length of the markers were measured with computer,and the results were statistically analysed.Results In computed orthopantomography,the uprightness distortion ratio of anterior teeth area of square mandibular arch(11.77%) was higher than that of tine mandibular arch(5.05%),and the difference was prominent(P=0.011

OBJECTIVE:To explore the spasmolytic effect of baked Radix Vladimiriae on in vitro intestinal muscle in rabbits. METHODS:Magnus in vitro intestinal muscle accumulative dose method was adopted to observe the dose-effect relationship of petroleum ether parts of baked Radix Vladimiriae with in vitro intestinal muscle of rabbits and its impact on the spasm of rabbit intestinal muscle induced by acetylcholine, histamine phosphate and Bacl2. RESULTS:There was a certain dose-effect relationship between petroleum ether parts of baked Radix Vladimiriae and spasmolytic mechanism of rabbit in vitro intestine. It showed the effect of acetylcholine, histamine phosphate and Bacl2. CONCLUSION:The inhibition effect of petroleum ether parts of baked Radix Vladimiriae on normal in vitro intestinal muscle increase as long as dose increase. The inhibition mechanism may be associated with acetylcholine competing with histamine to block M receptor and H1 receptor as well as to inhibit excitability of intestinal muscle.

Objective To explore the inhibiting effect of valsartan and spironolactone on cardiac fibrosis and the expression of integrin ? 1 and fibronectin in the heart of spontaneously hypertensive rats. Methods Eighteen 6 week old SHR were randomly divided into 3 groups with 6 in each: SHR control group, valsartan treating group(30 mg?kg -1 ?d -1 ) and spironolactone treating group ( 20 mg?kg -1 ?d -1 ). Six homogenous male WKY rats served as normal group. After 14 weeks of treatment, systolic blood pressure, left ventricular mass, the ratio of left ventricular mass to body weight (LVM/BW), collagen volume fraction(CVF) and perivascular collagen area(PVCA) were determined and compared among these groups. The expression of integrin ? 1 and fibronectin were also examined by immunohistochemical method. Results Compared with the untreated SHR S, systolic blood pressure was significantly decreased in both treatment groups. LVM/BW〔(2 84?0 14)?10 -3 vs(3 22?0 15)?10 -3 〕, CVF〔(3 21?0 22)%vs(4 00?0 28)%〕, PVCA〔(0 62?0 15)%vs(0 94?0 56)%〕 were lower in both treatment groups, these parameters in SHR V group were even lower than those in SHR S group. Compared with the untreated SHR S, the expression of integrin ? 1 was significantly reduced in SHR V group, while the expression of fibronectin was markedly reduced in both treatment groups. Conclusions Both valsartan and spironolactone could control blood pressure, and effectively inhibit the cardiac fibrosis. Valsartan could also inhibit the expression of cardiac integrin ? 1 and fibronectin, which might be the reason that valsartan is better than spironolactone in inhibiting cardiac fibrosis.

Objective To investigate whether Ulinastatin (UTI) would minimize the systemic inflammatory response,lessen cardiac dysfunction and protect neurons against injury in hippocampus CA1area after restoration of spontaneous circulation (ROSC). Methods Animal models of cardiac arrest were established in 24 New Zealand rabbits,and those animals were randomly (random number) divided into control group and UTI treated group after ROSC.Changes in the levels of plasma inflammatory cytokines TNF-α and IL-6 were assayed before cardiac arrest and 4,8,12 and 16 hours after ROSC.Cardiac function including FS,EF and E/A were observed with ultrasonography before cardiac arrest and 4,8,12 and 16hours after ROSC,and viable and apoptotic neurons in hippocampus CA1 area and infiltrations of MPO positive cells in myocardium,cerebrum,liver,kidney and intestine were counted 72 hours after ROSC.The t-test or Mann-Whitney rank sum test was used to verify the specified theoretical distribution functions of the biomarkers tested by Kolmogorov-Smirnov test,POST HOC test was used for the multiple comparisons,and Pearson correlation analysis was used to investigate the correlation between inflammatory cytokines and cardiac function. Results The levels of TNF-α and IL-6 in UTI group were lower than those in control group as those data got 4,8,12 and 16 hours after ROSC (P ＜0.05).EF and E/A in UTI treated group were higher than those in the control group as those data got 4,8,12 hours after ROSC.FS values obtained 4 h and 8 hours after ROSC were higher in UTI group than those in control group ( P ＜ 0.05 ).The Pearson correlation analysis showed that the levels of TNF-α and IL-6 significantly correlated with EF after ROSC.The number of viable neurons in CA1 area of control group was ( 13.22 ± 0.97) which was lower than that in UTI group ( 16.89 ± 1.45 ) ( P =0.003 ),while the number of apoptotic neurons in hippocampus CA1 area was higher in control group than that in UTI group (15.67 ± 1.37) vs.(13.67 ± 1.03 ) (P =0.019).The numbers of MPO positive cells were significantly lower in liver,kidney and intestine in group UTI than those in control group. Conclusions UTI could inhibit the infiltration of MPO positive cells in liver,kidney and intestine,decreasing the levels of TNF-α and IL-6 in plasma,in turn lessening cardiac dysfunction and protecting neurons from injury in hippocampus CA1 area after ROSC of New Zealand rabbits.
