Objective • To evaluate the recurrence rate of atrial fibrillation (Af) and its related risk factors in aged patients with chronic diseases after cryoballoon ablation. Methods • With the method of convenient sampling, a total of 159 patients with Af after cryoballoon ablation were enrolled in the Department of Cardiology, Ruijin Hospital from Oct. 2016 to Jan. 2018. Self-rating depression scale (SDS) and CHA2DS2-VASc scores [congestive heart failure, hypertension, age ≥ 75 y (doubled), diabetes mellitus, stroke(doubled)-vascular disease, age 65-74 and sex category(female)] were used to assess the patients. Follow-up checks consisted of chief complaint, postoperative electrocardiogram (ECG), and 24 h Holter monitoring. Logistic regression models were performed to explore the independent risk factors of Af recurrence after cryoballoon ablation. Results • 152 patients (95.6%) completed the follow-up checks, with an average age of (61.9±8.9) years. The average time of follow-up period was (8.35±2.41) months. A total of 41 patients (27.0%) developed Af after cryoballoon ablation. Logistic regression analysis showed the number of chronic disease ≥ 2 (OR=2.466, 95% CI: 1.375-4.452), CHA2DS2-VASc scores ≥ 2 (OR=2.088, 95% CI: 1.142-5.557), irregular use of anti-arrhythmic drugs (OR=1.581, 95% CI: 1.351-2.125), hypertension (OR=1.317, 95% CI: 1.076-2.809), and body mass index (BMI) (OR=1.147, 95% CI: 1.009-1.174) were the independent risk factors of Af recurrence. Conclusion • There is still a certain percentage of recurrence in aged patients with chronic diseases after cryoballoon ablation. 2 and more chronic diseases, irregular use of anti-arrhythmic drugs, hypertension, CHA2DS2-VASc scores ≥ 2, and overweight may be potential risk factors of Af recurrence after cryoballoon ablation.

Objective By means of analyzing the antihypertensive use of hypertension patients of Guiyang in 2013 and impact factors for basic drug use,to evaluate the impacts of the essential medicines list in place in Guiyang to hypertension patients in communities in Guiyang.Methods 969 hypertension patients were surveyed with structured questionnaire of stratified random sampling at 6 community health centers in Guiyang city.Results Hypertension patients in communities averaged 1.4 types of antihypertensive,and the essential medicines used accounted for 39.8％of all the antihypertensive.The distribution differences of the ratio of essential medicines use are significant interms of age,gender,and household annual income.Use ratio of non-essential medicines of the 55～64 age group and 65～74 age group are 3.48 times and 0.47 times over that of the 75 and above age group.For hypertension patients of low income and medium income,their probable use of non-essential medicines is 2.05 and 2.87 times that of high income households.Conclusion As the use ratio of hypertension patients in Guiyang is relatively low,and the factors for it are age and household income,focused intervention is recommended for the 65～74 age group and low-income households,for the purpose of high use ratio of essential medicines of such people.

Objective To clone and express the encoding sequence of glyceraldehydes-3-phosphate dehydrogenase(GAPDH)from periodic Brugia molayi(Bm).Methods Total RNA was extraeted from periodic Brugic malayi.The BmGAPDH gene was amplified by RT-PCR.The PCR product was cloned and then subeloned into pcDNA3.1(+)vector.The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification,and were transformed into COS-7 cell subsequently.The expressed protein was identified by SDS-PAGE.Results BmGAPDH mRNA was highiy expressed in transfected COS-7 cell.The deduced amino acid sequence was identical with that of BmGAPDH.The recombinant pnotein wag about Nr 43 000.Conclusion The recombinant plasmid peDNA3.1(+)-BmGAPDH has been constructed and the protein has been expressed correctly.

Background/Aims: The effect of physical activity on the relationship between dietary fiber intake and constipation has not been comprehensively studied.This study aims to explore the impact of physical activity. Methods: Data were obtained from 3 cycles of the National Health and Nutrition Examination Survey (NHANES) 2005-2010 and included a total of 13 941 participants aged ≥ 20 years. Multiple logistic regression analysis was used to investigate the independent associationbetween dietary fiber and constipation. Interaction analysis was also performed to analyze the relationship between dietary fiber and constipation in different physical activity groups. Results: Among non-active participants, dietary fiber intake did not associate with stool consistency (OR, 1.02; 95% CI, 0.98-1.05; P = 0.407). For physically active participants, 1-gram unit increase in dietary fiber intake reduced the risk of stool consistency by 3% (OR, 0.97; 95% CI, 0.94-0.99; P = 0.020). Moreover, the relationship between dietary fiber intake and stool consistency was significantly different for groups with different levels of physical activity (P interaction = 0.044). However, dietary fiber intake was not related to stool frequency among non-active participants (OR, 0.99; 95% CI, 0.94-1.05; P = 0.767) nor physically active participants (OR, 1.01; 95% CI, 0.97-1.04; P = 0.751). Conclusions Increasing dietary fiber intake was associated with stool consistency-related constipation among physically active participants, but not among non-active participants. However, increasing dietary fiber intake is not significantly associated with stool frequency in different physical activity groups.

OBJECTIVETo research the change of concentration of the amino acid neurotransmitters in the striatum focal cerebral ischemia in rat and the effect of Acorus tatarinowii Schott, one of inducing resuscitation drugs, for 4 of amino acid neurotransmitters.

METHODSTwenty four rats were divided into four groups (n = 6): control group, cerebral ischemia group, sham operation group and Acorns tatarinowii Schott treated group. Rats were established into models of cerebral ischemia by occluding bilateral thread cork method. Formation sampling were performed in a striatum area using microdialysis and the detection of biological sample including aspartic acid, glutamic acid, glycine and gamma-aminobutyric acid by high performance liquid chromatography (HPLC) electrochemical detector system.

RESULTSCompared with the control, the all contents of 4 kinds of the amino acids were significantly increased during cerebral ischemia (P < 0.01). Compared with the cerebral ischemia group, the contents of aspartic acid, glutamic acid that were excitatory amino acids were remarkably decreased in the striatum for Acorus tatarinowii Schott treated group (P < 0.01), It was no significant influence on gamma-aminobutyric acid and glycine that belonged to inhibitory amino acid in a nascent condition but with a elevating in the later period of microdialysis.

CONCLUSIONAcorus tatarinowii Schott can enter the cerebral parenchyma through blood brain barrier and cut down glutamic acid,aspartic acid increased during cerebral ischemia. As a result, the neurotoxicity attributed to the excitatory amino acid has been released in excessive amounts declined so as to avoid the secondary impairment of neurons caused by excitatory amino acids pernicious effects after ischemia. It may be one of the protective mechanism of drugs for inducing resuscitation resembling EAA receptor antagonists to ischemi brain.

Slow transit constipation(STC)is the common type of chronic idiopathic constipation. Due to failure of routine conservative treatment, laxatives abuse is the most choice for majority of the patients, which could damage the enteric nervous system and result in aggravation of constipation. Resection of the slow transit colon is the ultimate option for some patients. It is hard to prevent and treat STC clinically because of the unknown pathophysiologic mechanism. Abnormalities of enteric neurotransmitters such as VIP, SP, NOS and decreased number of interstitial cells of Cajal have been described in the colon of the patients with STC. However, long term application of stimulant laxatives can also result in the almost same changes in the colon. Exploration of the potential relationship among the above reported abnormalities is the direction of future study.
