OBJECTIVE:To observe clinical efficacy of Felodipine sustained-release tablets(Ⅱ)in the treatment of elderly es-sential hypertension and its improvement effect on arterial elasticity,left ventricular remodeling and the quality of life. METHODS:A total of 96 elderly patients with essential hypertension in our hospital during Aug. 2014-Dec. 2015 were divided into observation group (50 cases) and control group (46 cases) according to random number table. Observation group was given Felodipine sus-tained-release tablets(Ⅱ)5 mg orally,qd,with empty stomach in the morning;control group was given Irbesartan tablets 150 mg, qd,with empty stomach in the morning. Both groups received treatment for 12 weeks. Clinical efficacies of 2 groups were observed as well as 24 h ambulatory blood pressure (ABP),indexes of arlerial elasticity [carotid-radial pulse wave velocity (CR-PWV),carot-id-femoral pulse wave velocity (CF-PWV)], indexes of left ventricular remodeling [diastolic interventricular septum thickness (IVST),diastolic left ventricular posterior wall thickness(LPWT),left ventricular end diastolic diameter(LVIDd)] before and after treatment. The physiological function (PF),social function (SF),role-physical (RP),body pain (BP),mental health (MH),role-emotional(RE),vitality(VT)and general health(GH)score of SF-36 were observed in 2 groups before and after treatment. The occurrence of ADR was compared between 2 groups. RESULTS:There was no statistical significance in total response rate be-tween 2 groups (P>0.05). There was no statistical significance in 24 hABP,CR-PWV,CF-PWV,IVST,LPWT,LVIDd,SF-36 score between 2 groups before treatment(P>0.05). After treatment,the levels of 24 hSBP,24 hDBP and 24 hMAP in 2 groups were decreased significantly,and 24 hSBP and 24 hMAP of observation groups were significantly lower than those of control group,with statistical significance (P<0.05). There was no statistical significance in 24 hDBP (P>0.05). The levels of CR-PWV,CF-PWV, IVST and LPWT in observation group were decreased significantly,and the levels of CR-PWV and LPWT in control group were also decreased significantly. The levels of CR-PWV,CF-PWV,IVST,LPWT and LVIDd in observation group were significantly lower than control group,with statistical significance (P<0.05). SF-36 scores of 2 groups were increased significantly,and the scores of BP,VT,MH and GH in observation group were significantly higher than control group,with statistical significance (P<0.05). There was no statistical significance in scores of PF,SF,RP and RE. There was no statistical significance in the incidence of ADR be-tween 2 groups(P>0.05). CONCLUSIONS:Felodipine sustained-release tablets(Ⅱ)exhibit significant effect and small blood pres-sure fluctuation in the treatment of elderly essential hypertension,and can improve the quality of life with good safety.

Objective To develop a sensitive, simple, and accurate method for the determination of shionone in rat plasma after ig administration of Asteris Radix petroleum ether extract (RAPE).

Objective To study the influence of Noradrenergic systems in Lateral Hypothalamus Area (LHA) on small intestine moving. Methods The effect of noradrenalin、noradrenalin+phentolamine、noradrenalin+propolol、phentolamine on small intestines electro-activity of rats was detected by external alimentary canal electrodes and central nervous system stereo-configuration technology. Results After injecting 2 g/L noradrenaline (NE) the cyclic period of MMC extended, the ratio of the active time to the cyclic period and the number of the fast wave within the active time per minute reduced. NE inhibited the electro-activity of small intestine of rats, and the average effective time was (36.86?7.39)min. Hence injecting 5 g/L PE alone to LHA raised the ratio of the MMC active time to the cyclic period. Phentolamine presented a slight excitability on the electro-activity of small intestine of rats. Conclusion The NE in LHA showed the inhibitive myoelectric activity on small intestines, and this effect was introduced through a acceptor,The reacceptor in LHA may function in the inhibition of the electro-activity in small intestines.

Objective:To discuss the relationship between the geographic environment and blood urea nitrogen(BUN) reference values of the healthy people,and to explore the distributional rule of BUN reference values of the healthy people,and to provide the scientific foundation for establishing the BUN reference value standards of different areas.Methods:A total of 23 geographic factors and 33 521 BUN reference values of healthy adults measured by 403 medical facilities from 23 provinces,4 municipalities and 5 autonomous regions were collected.The spatial autocorrelation analysis was used to determine the spatial autocorrelation of the sample data;the correlation analysis was used to detect the factors which correlated significantly with the BUN reference values;the multiple linear regression,principle component analysis and ridge regression analysis were respectively used to construct the predicted models;the paired-sample t test was used to choose the optimal model;the distribution map of BUN reference values was built by geostatistic analysis.Results:There were 5 geographic factors,latitude(X2),altitude(X3),annual mean temperature(X5),annual mean relative humidity(X6) and annual precipitation(X7),correlated significantly with the BUN reference values.The regression equation of optimal model was Y^=5.112+0.000 127 1X2+0.000 094 61X3-0.000 140 5X5-0.000 136 8X6-0.000 139 1X7±0.531 0;the distribution map of predicted values of the BUN reference values was obtained.Conclusion:The overall trend of BUN reference values is low in the east and high in the west.The BUN reference value is negatively associated with the altitude.If the geographic data of a certain region could be obtained,the BUN reference value of this region will be predicted.

OBJECTIVE To study the diagnosis and management of epistaxis caused by traumatic pseudoaneurysm.METHODS The clinical data of 16 cases with epistaxis caused by traumatic pseudoaneurysm were retrospectively studied.There were 12 males and 4 females.Their ages ranged from 16 to 41 years with an average of 25.4 years.RESULTS All the patients were cured via digital subtraction angiogrophy(DSA) and embolization except one died.The time between the hospitalization and the DSA examinat ion was 3 to15 days.Interestingly,every patient had received anterior and posterior nasal packing one to 5 times.CONCLUSION If the anterior and posterior nasal packing were not effective to the patients with repeated and vast nasal bleeding,who had trauma history before nasal bleeding,the DSA examination should be carried out immediately to identify whether the pseudoaneurysm exists.
