Objective To investigate the associations of atrial natriuretic peptide(ANP)rs5065 and brain natriuretic peptide(BNP)rs198389 gene polymorphisms with human essential hypertension(EH).Methods A total of 976 patients with EH and 976 age-and sex-frequency matched normotensive(NT)control subjects were collected.The ANP rs5065 and BNP rs198389 polymorphisms were genotyped by real-time quantitative polymerase chain reaction(real-time Q-PCR)method--Taqman probe.Results There was significant difference in frequency distribution of AA and AG+GG genotypes,A and G allele of BNP rs198389 between the EH and NT groups(P＜0.05).The frequency of AG+GG genotype and G allele was significantly higher in the EH group(30.5% and 17.3%)than in the NT group(26.1% and 14.1%).There was no difference in distribution of ANP rs5065 polymorphism between EH and NT groups(P＞0.05).By unconditional Logistic regression analysis of rs198389,before adjusted for the EH risk factors,AG+GG genotype presented a significantly higher risk of EH(P=0.04)than AA genotype,and this risk was still significant after adjusted for the EH risk factors(P=0.02).G allele had more significantly increased risk of EH than A allele(P=0.04).However,there was no significant difference before or after adjusted for the EH risk factors in unconditional Logistic regression analysis of rs198389.Conclusion rs198389 polymorphisms of BNP gene may be associated with EH,but rs5065 polymorphisms of ANP gene may be not associated with EH.

OBJECTIVETo verify the clinical efficacy on post-stroke dysphagia treated with acupuncture at Lianquan (CV 23).

METHODSOne hundred and eighty patients were randomized into an acupuncture A group, an acupuncture B group and a rehabilitation group, 60 cases in each one. On the basis of the conventional medication, in the acupuncture A group, acupuncture was applied at Lianquan (CV 23); in the acupuncture B group, acupuncture was applied at Hegu (LI 4) and Neiguan (PC 6) and in the rehabilitation group, the swallowing rehabilitation training was adopted. The treatment was given once a day, 5 times a week, and the 4 weeks of treatment was required in all of the groups. The national institute of health stroke scale (NIHSS) and TV X-ray fluoroscope swallowing scale (VFSS) were used to evaluate neurologic deficit and swallowing function before and after treatment in the patients of each group. The morbidity of pneumonia and clinical efficacy were compared among the groups.

RESULTSThe scores of NIHSS and VFSS were improved apparently after treatment in the patients of the three groups (all P < 0.05) and the results in the acupuncture A group were superior to those in the other two groups (all P < 0.05). The morbidity of pneumonia in the acupuncture A group was lower than that in the acupuncture B group and the rehabilitation group [3.3% (2/60) vs 6.7% (4/60), 8.3% (5/60), both P < 0.05]. The effective rate in the acupuncture A group was better than that in either of the other two groups [95.0% (57/60) vs 81.7% (49/ 60), 75.0% (45/60), both P < 0.05].

CONCLUSIONOn the basis of the conventional medication, acupuncture at Lianquan (CV 23) effectively improves the swallowing function, relieves neurological deficit and reduces the morbidity of pneumonia in the patients of post-stroke dysphagia.

Objective: To prepare Lingyi Formula multicomponent microemulsion and evaluate its anti-lung cancer activity. Methods: Lingyi Formula multicomponent microemulsion was prepared by aqueous titration method using polysaccharides solution of Ganoderma lucidum and Coix lachryma-jobi var. ma-yuen as aqueous phase and coix seed oil as oil phase, loading ganoderma triterpenes. The average particle size, Zeta potential, and stability were detected. The results of antitumor efficacy including tumor inhibitory rate, body weight change, immune organ index, and concentration of TNF-α and IL-6 were investigated. Besides, pathological section of tumor tissue and TUNEL labeling were conducted subsequently. Results: The prepared microemulsion displayed spherical surface with mean droplet size of (69.92 ± 8.43) nm, polydispersity (PDI) of 0.060 ± 0.008, and Zeta potential of (-11.30 ± 1.34) mV. Tumor inhibitory rate of microemulsion (57.25%) was significantly higher than that of suspension (45.89%), immune tissue index as well as the concentration of TNF-α and IL-6 were increased significantly. TUNEL labeling and pathological section of tumor tissue showed that the antitumor activity of microemulsion was significantly effective compared with that of suspensions. Conclusion: Lingyi Formula multicomponent microemulsion has a good anti-lung cancer activity.

Objective To evaluate the cancer risk of benzene and formaldehyde in different indoor air environments in Guiyang city.Methods From 2004 to 2005,benzene and formaldehyde monitoring was conducted in bedrooms,living rooms, kitchens,offices,classrooms and outdoor environments in winter,spring and autumn,and human health risk assessment was done. Results The mean benzene and formaldehyde concentration in different environments were lower than the China indoor air quality standard except for formaldehyde concentration in offices.The benzene cancer risks of male and female adults were 1.63?10~4 and 1.40?10~(-4)respectively.The formaldehyde cancer risks of male and female adults were 6.05?10~(-4)and 5.23?10~(-4) respectively.The human formaldehyde cancer risk was higher than benzene cancer risk,and the risk for male was higher than that for female.Benzene and formaldehyde cancer risks of different population in different indoor environments were above 1.00?10~(-6), the acceptable level of human cancer risk.Conclusion The benzene and formaldehyde concentrations in different environment in Guiyang city has the high cancer risks to human health.

The effects of grape seed oil on serum total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) levels were investigated in experimental hypercholesterolemic rats. The grape seed oil containing about 74% linoleic acid, multivitamins and trace elements. Each animal was given 4 ml/kg BW grape seed oil mixed in high fat ration for 40 days. The results in two experiments showed that TC concentration in the serum of rats fed grape seed oil was markedly lowered as compared to control, but serum HDL-C was less lowered. Furthermore, the ratio of HDL-C to TC in the experimental group was also significantly higher than that of control.

Objective To explore the expression of plasminogen activator inhibitor-3 (PAI-3) in normal adult skin. Methods Immunohistochemistry and RT-PCR were used to detect the expressions of PAI-3 and uPA. Results mRNA of PAI-3 and uPA were detected. PAI-3 was mainly expressed in stratum basale, stratum spinosum and stratum granulosum, and its expression enhanced in the well differentiated keratinocytes of the epidermis. uPA was located in basal layer. Conclusion PAI-3 exists in normal adult skin and is related with the differentiation of epidermal keratinocytes.
