Objective To study the effects of high salt intake on blood pressure and renin-angiotensin in male rats with different plasm androgen levels.Methods Thirty male Wistar rats were randomized to sham(n=10)or operated(n=10),or castration(n=10),or testosterone replacement after castarion(26.7 mg/kg,n=10)and fed with 8% NaCl for 8 weeks.Tall arterial pressure were recorded before,4 and 8 weeks after experiment.Serum PRA,plasma angiotensin Ⅱ(Ang Ⅱ)and testosterone(T)were determined by radioimmunoassey respectively. Results After 8 weeks high salt dietary,blood pressure was significantly increased in sham and testosterone replace ment rats(Sham operation group:137.3?4.0 vs the basal line:117.5?5.9 mmHg,testosterone replacement group: 134.4?5.2 vs the basal line:116.6?7.7 mmHg,P0.05).Concomitantly,sham operation or testosterone re placement rats had higher PRA and plasm Ang Ⅱ content compared with castrated rats(PRA:Sham operation 5.90 ?0.77 vs testosterone replacement group:5.69?0.47 vs castrated rats:4.90?0.55 mol/(L?h),P

A new non-destructive and rapid method was developed to discriminate the coating process of Rukuaixiao tablets mainly based the support vector machine (SVM) with the near-infrared spectroscopy (NIRs). After the samples that differ in the sugar-coat were acquired, the sample set partitioning based on joint x-y distance (SPXY) method was used to select the training sets and internal principal component analysis (internal PCA) was to select the optimal wavelength. The discrimination model was developed based on support vector machine (SVM), and varieties of pre-processing methods were compared. The results showed that the accuracy of the prediction set was 98.81%. It is concluded that the accuracy of the method is high to use for the quality evaluation of tablet's coating process.

s:The partical coding sequence of E2 gene of 13 Hog Cholera Virus(HCV) field isolates, Shimen strain, Chinese vaccine strain(C strain) and Thiverval strain attenuated by low temperature in France,were obtained by reverse trancriptase -polymerse chain reation (RT-PCR) and sequenced.All size were 251bp.The obtained 224bp sequences were analysed by DNA star and compared with the previously published sequences of Alfort strain ,Brescia strain and other references strains.The results showed that those sequencing fragments of 13 HCV field strains were the sequence of E2 gene of HCV.Compared with Shimen strain,the base substitute of all stains were randomly distributed in the entire sequence,and had not base insert and base gap.The variation most occurred at 3' end. The identity of nucleotide sequence and amino acid sequenceof 22 HCV strains were 78.1%～100%?78.4%～100%. The identity of nucleotide sequence and amino acid sequence of 13 HCV field strains were 78.1%～100%?78.4%～100%.The identity of nucleotide sequence and amino acid sequence of 4 HCV field strains isolated in the 1970s～1980s were 79.0%～88.3%?81.1%～87.8%.The identity of nucleotide sequence and amino acid sequence of 9 HCV field strains isolated in the 1990s were 80.8%～100%?83.8%～100% respectively. This paper showed that the genetic variation of HCV was diversity.

OBJECTIVETo observe and identify the effect of Jiangya Maijing Liquid (JYMJL) on spontaneous hypertension rats (SHR) fed with high lipid diet in antagonizing hypertension and hyperlipidemia and improving pathological changes of kidney.

METHODSForty-two SHR were divided into 5 groups, except Group A, the Groups B-E were fed with high lipid diet, and Group C, D and E was treated with JYMJL, western drug and Niuhuang Jiangya pill respectively. Besides, Group F was set up for control with normal rats fed by normal diet. The changes of blood pressure (BP), biological indices and renal pathology were observed in the 14 weeks' period of observation.

RESULTS(1) BP raised significantly in Group A and B, it became stable in Group C from the 5th week on and was lower than the BP in other groups (P < 0.01). BP in Group F was not changed; (2) The highest level of nitric oxide (NO) was shown in Group F, and that in Group B and E was lower than that in Group C and D; (3) Level of cholesterol was lower in Group A and F than that in Group C, D and E (P < 0.01), and that in Group C was lower than that in Group B and E (P < 0.01 and P < 0.05 respectively); (4) Pathologic examination on kidney showed that no change was found in Group F, the most severe change was shown in Group B among Group B-E, and the improvement after treatment in Group C was better than that in group B (P < 0.01).

CONCLUSION(1) Condition of disease in rats with hypertension complicated with hyperlipidemia was more severe than that with simple hypertension; (2) JYMJL could restrain the developing of hypertension in SHR, the mechanism may be related with the raising of NO; (3) JYMJL has effect of lowering blood lipid; (4) JYMJL has kidney protective effect, it could alleviate the pathological changes in kidney by way of lowering BP and blood lipid.

OBJECTIVETo observe the effect of garlicin on adhension molecules CD11a and deformability of peripheral neutrophil in patients with acute cerebral infarction (ACI).

METHODSNeutrophils were separated from peripheral blood of healthy subjects and ACI patients, and incubated in 37 degrees C in vitro. The CD11a expression was detected by antibody fluorescence labeling method and the time of neutrophils passing millipore membrane were measured for calculation of the filter index.

RESULTSCD11a expression rate in healthy subjects was 34.64 +/- 25.34%, while in patients was 55.35 +/- 30.54%, difference between them was significant (P < 0.05). After garlicin treatment, it lowered to 49.16 +/- 31.68%, as compared with untreated group, P < 0.05. The neutrophil filter index in healthy group, untreated group, garlicin treated group and Nimodipine treated group was 0.87 +/- 0.46, 6.42 +/- 6.40, 3.47 +/- 3.67 and 5.03 +/- 3.72 respectively, comparison between that in the garlicin treated group and in untreated group showed significant difference (P < 0.05).

CONCLUSIONGarlicin could effectively inhibit the CD11a expression in peripheral blood neutrophils and improve the deformability of the neutrophils in ACI patients.

Abstract: Objective　To analyze the epidemiological characteristics of public health emergencies in Xishuangbanna Dai Autonomous Prefecture from 2012 to 2021, and to provide reference for formulating relevant prevention and control measures. Methods　The data of public health emergencies reported in Xishuangbanna from 2012 to 2021 were collected and analyzed through the China Disease Prevention and Control Information System. Results A total of 78 public health emergencies (including "Unrated" events) were reported in Xishuangbanna from 2012 to 2021. The highest 21 cases and the lowest 3 cases were reported every year. A total of 1 0374 cases were reported in 78 public health emergencies, involving a population of 1 703 049, with a morbidity of 609.14/100 000, 24 deaths, mortality of 1.41/100 000 and fatality rate of 231.35/100 000. The event level was mainly "general (level Ⅳ)" with 52 incidents, accounting for 66.67%, and 17 incidents of "major (level Ⅲ)", accounting for 21.79%. 51 cases were mainly infectious diseases, accounting for 65.39%. The peak periods for incidents were May-July and November-February of the next year; there were 39 incidents in schools, accounting for 50%, followed by 20 incidents in families, accounting for 25.64%. The top three reported cases were food poisoning (32.05%), chicken pox 17 (21.79%) and dengue fever 10 (12.82%). Among the 24 deaths in public health emergencies, 22 were caused by food poisoning. Wild bacteria poisoning and alcohol poisoning were the main causes of food poisoning, accounting for 45.83% and 37.5% of the total deaths, respectively. Conclusion Infectious diseases, especially respiratory diseases and food poisoning are the focus of the prevention and control of public health emergencies in Xishuangbanna Dai Autonomous Prefecture, of which Schools and families should be pay close attention. Plague, a Class A infectious disease, caused by the bacterium Yersinia pestis has occurred in two inter-animal outbreaks in 10 years and spread to the population, which should be of great concern.
