[Objective] Preliminarily clear the effective substance of Fuzi in treatment of AA by comparing the NO, TNF-α and toe volume in AA rats affected by diester alkaloids,monoester alkaloids and non-ester alkaloids. [Methods]Male wistar rats were randomly divided into comparing group and model group. FCA was given in the left rear toe of rat in model group(once a day,0.1mL each). After 2 weeks ’injection, model rats were randomly divided into model group, diester alkaloids group, monoester alkaloids group and non-ester alkaloids group. Rats in comparing group and model group were given physiological saline and others were given corresponding alkaloids. Detect the NO,TNF-αand toe volume after 2 weeks. [Results]Compared with the model group, the weight gain of rats in other group was suppressed(P<0.05). Compared with the model group, the toe volume and the NO, TNF-αof rats in the alkaloids groups reduced significantly(P<0.01).The toe volume of rats in monoester alkaloids group reduced more obviously. The NO of rats in diester alkaloids group and non-ester alkaloids group reduced more significantly than the rats in monoester alkaloids group( P<0.05). [ Conclusion] The diester alkaloids, monoester alkaloids and non-ester alkaloids in Fuzi al have a significant effect on AA rats and the effect of the monoester alkaloids is the best.

[Objective] To establish a content determination method of Berberine hydrochloride in San Yu Ointment by HPLC.[Methods] RP-HPLC was performed to determine Berberine hydrochloride on a column of Agilent Zorbax Eclipse XDB-C8(4.6?150mm,5?m)at 20℃; Acetonitrile-0.1 % H3PO4 (50∶50)(Adding 0.1 g C12H25NaO4S to every 100 mL)was used as mobile phase,the flow rate was 1.0 mL?min-1.The detection wavelength was at 265 nm.[Results]A good linearity can be found in the range of 39.40 ~394.0 ng,and the regression equation was Y = 4.073?103x+2.248 ? 103 (r=0.9992).The recovery was between 97.9 %~100.9 %,and the average recovery rate was 99.4 %,RSD was 1.5 %.[Conclusion]The method is simple,rapid,accurate and available,which can be used to control the quality of San Yu Ointment.

Objective To make a passive personal sampler for the determination of the styrene in the air. Methods To make a passive personal sampler for the determination of the styrene in the air. Results Under the condition of wind velocity of 100-600 cm/s, relative humidity of 40%-80% and temperature of 10-40 ℃, the sampling flux of the passive sampler was 61.8 ml/min, the capacity was 5.95 mg, the shortest sampling time was 30 min, the self life was at least 30 days, the storage stability was at least 14 days, the RSDs were 8.07%-9.37%. Conclusion This new kind of passive personal sampler can be used as a new device for the determination of the styrene in the air.

Seventy eight patients suspected of intrauterine adhesion (IUA) were scanned with two-dimensional (2D) and three-dimensional (3D) transvaginal uhrasonography, the results were analyzed with hysteroscopic findings as the gold standard. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of three-dimensional transvaginal ultrasonography in diagnosis of IUA were 97% (58/60), 18/18, 97% (76/78), 100% (58/58) and 90% (18/20). Three-dimensional transvaginal ultrasonography was more accurate in diagnosis of IUA than two-dimensional ultrasonography ( P < 0. 01 ),and the IUA classification and grading with three-dimensional transvaginal ultrasonography was better correlated with hysteroscopic findings.

The ratio of plasma aldosterone concentration to plasma renin activity (ARR) is a practical parameter in screening for primary aldosteronism (PA).However,variations of the cutoff value of ARR in different studies have been reported due to plenty of influential factors that may affect the secretions of renin and aldosterone. Lack of standardization of assays for ARR also makes direct comparisons among different studies difficult.The associated influential factors on ARR were introduced in this review.

Objective:To compare the models of guinea pig allergic rhinitis induced by different allergens. Methods: Ovalbumin (OVA), 2,4-tolylene diisocyanate (TDI) and alternariaalternata was respectively used as the allergens to establish the model of guinea pigs allergic rhinitis. The conformity of the models and human allergic rhinitis was studied through the behavioral indices, such as the times of nose itches, nasal discharge flow, histological properties and serum HA and IgE indices. Results:The times of sneezing and scratching nose, serum HA and IgE in OVA group was significantly different from those in the control group (P<0. 001 or P<0. 01). Conclusion:The models of allergic rhinitis induced by OVA are the same as allergic rhinitis in typical symptoms and pathological changes.

The necessity to apply medical devices properly was introduced, and the present situation of the application of hospital medical devices were discussed from the aspects of overuse, abuse, operation and supervision. Some countermeasures were put forward to solve the problems in the application of hospital medical devices. It's pointed out that the application of hospital medical devices tends to be standardized with the progress of medical reformation, the attention on medical devices management, the supervision and etc.
