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.

Chinese Acupuncture & Moxibustion 2014;34(7):627-630
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.

BACKGROUND: Xiongbitong capsule (capsule) increases blood flow in myocardial ischemic area in patients with coronary heart disease, lessens the size of myocardial infarction and improves ischemic S-T alternation in electrocardiogram (ECG).OBJECTIVE: To observe the effect of the capsule on NO metabolism on arterial wall in rabbits and explore the improvement of such drug on myocardial blood flow and protection on myocardium.DESIGN: Randomized group division and control experiment were designed.SETTING: Department of First Internal Medicine, Hospital of Traditional Chinese Medicine, Weifang, Shandong.MATERIALS: The experiment was performed in Teaching-Research Room of Physiology of Weifang Medical College from April 2003 to February 2004. Totally 30 healthy adult rabbits were employed, of either sex and randomized into 3 groups, named normal control, model group and treatment group, 3 rabbits in each one.METHODS: ① Preparation of hyperlipemia (HP) model: In normal control, common granular forage was used. In model group, modeling forage was applied (common granular forage + 3% pig oil + 1% cholesterol powder). In treatment group, besides modeling forage, at the end of the 6th week, the capsule [composed of taizishen (Radix Pseudstellariae), yunling (Poria), gualou (Frnctus Trichosanthis), qingxia (Rhizoma Pinelliae), juhong (Exocarpium Citri Grandis), shichangpu (Rhizoma Acori Graminei), yujin (Radix Curcumaea), zhifuhua (Flos Inulae), jiangxiang (Lignum Dalbergiae Odoriferae), danggui (Radix Angelicae Sinensis), maidong (Radix Liriopis Platyphyllae) and wuweizi (Frnctus Schisandrae).] was administrated every day for gastric perfusion at 1 pill/kg with 10 mL physiological saline for 3 weeks. The intervention was applied totally for 8 weeks. ② Nitrieoxide synthase (NOS) and NO metabolic product kits were provided from Radiation Medical Institute of Military Academy of Medical Sciences. The operation was based on the instrnction. NOS activity was calculated and expressed by NO amount (nmol) produced in one-gram tissue per minutes.Spectrophotometer was used to measure the optic density of sample at 545nm. Sodium nitrite solution was used to prepare standard curve. The concentration of serum NO metabolic products, NO2- and NO3- was expressed with μmol/L. ③ T test was applied for difference comparison among measurement data.MAIN OUTCOME MEASURES: Comparison of NOS activity and concentration of serum NO metabolic products in vessel-wall tissue in eachgroup.RESULTS: Totally 30 rabbits all entered result analysis. For NOS activity and concentration of serum NO metabolic products in arterial-wall tissue,the results in model group and treatment group were lower remarkably than the control (P < 0.05-0.01) and the results in treatment group were higher remarkably than model group (P < 0.05).CONCLUSION: ① NO system of arterial wall is damaged in HP rabbits and NO metabolic level is decreased in serum. ② Xiongbitong capsule improves the above situation and brings the resistance of myocardial ischemia and protection of myocardium into play.
