Background:Gastroesophageal reflux disease(GERD)is a common disease,its incidence is related to geographic environment and race. Studies reported on epidemiology of GERD in minority groups are rare. Aims:To investigate the prevalence and related risk factors of GERD in She population in Ningde. Methods:Three natural villages of She population in Ningde were selected for undergoing the cluster random sampling method. GERD was diagnosed by gastroesophageal reflux disease questionnaire(GerdQ)with score ≥8,and questionnaire was used to detect the prevalence and risk factors of GERD. Results:A total of 936 residents completed the questionnaire,and 89 were diagnosed as GERD, the prevalence was 9. 50% . Univariate analysis showed that the risk of GERD was significantly increased in She population with body mass index(BMI)≥24 kg/ m2 ,intake of strong tea or oily diet(P all < 0. 01). Multivariate analysis showed that BMI ≥24 kg/ m2(OR = 3. 022,95% CI:1. 917-4. 765),intake of strong tea(OR = 2. 145,95% CI:1. 338-3. 438) and oily diet(OR = 2. 016,95% CI:1. 208-3. 318)were the risk factors of GERD. Conclusions:The prevalence of GERD is high in She population in Fujian Province,and the etiology may be related to overweight and diet habit.

Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.

OBJECTIVETo analyze the effects of acupuncture on the level of atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP) in adrenal gland and the content of corticosterone (CORT) in plasma in rats withchronic emotional stress anxiety, and to explore the partial action mechanism of acupuncture on anxiety disorder.

METHODSThirty-two healthy Sprague-Dawley (SD) rats, after 7 days of feeding and domestication, were randomly divided into a blank group (10 rats), a model group (11 rats) and an acupuncture group (11 rats). The rats inthe model group and acupuncture group were treated with unpredictable chronic emotional stress (CES) method toestablish the model of anxiety. Rats in the acupuncture group were treated with acupuncture at "Neiguan" (PC 6)and "Shenmen" (HT 7), once every other day, 30 minutes each time. The model establishment and treatment lasted 15 days. Rats in the blank group were treated with identical immobilization but no treatment was given. Theelevated plus maze was used to test the behavioral changes of rats with anxiety; the level of CORT in plasma wasdetected by ELISA, and the expression level of CNP and ANP in adrenal cortex and medulla was detected by immunohistochemical method.

RESULTS(1) The percentage of open-arms time in total time (OT%) in elevated plus maze in the model group was significantly lower than that in the blank group (P<0. 05); the OT% in the acupuncture group was significantly higher than that in the model group (P<0.01). (2) The content of CORT in plasma in the model group was higher than that in the blank group (P<0. 05), while that in the acupuncture group was significantly lower than that in the model group (P<0. 05). (3) The expression of ANP in adrenal medulla and cortex in the model group was lower than that in the blank group (P<0. 01), while the expression of CNP in adrenal medulla and cortex in the model group was higher than that in the blank group (P<0. 01).

CONCLUSIONThe effects of acupuncture against anxiety are likely to be related to the regulation on the expression of ANP and CNP in adrenal medulla, affecting the release of CORT and inhibition on the activity !f hypothalamic-pituitary-adrenal axis (HPA axis).

Objective: To study the pharmacokinetics and brain/plasma concentration ratio of nortriptyline at multiple doses in mice which were pre-treated with physiological saline, piperine and verapamil. Methods: A total of 216 male Kun Ming mice[(25±3) g] were equally divided into 4 groups randomly. Each group was intragastrically administered physiological saline (B), piperine (170 μg/kg), piperine (5 mg/kg) and verapamil (5 mg/kg) for 8 days. On the 8th day, 1 h atfer giving the above drugs, each mice was intraperitoneally injected nortriptyline (13 mg/kg). The mice were sacriifced by picking off eyeballs at the time intervals of 5, 15, 30 min, and 1, 2, 4, 6, 8 and 12 h, andthe cerebra were collected and weighted. Nortriptyline in mouse plasma and brain was determined by HPLC-MS/MS. The pharmacokinetic properties of the plasma, brain and brain/plasma were calculated. Results: hTe AUC0-12 h of brain/plasma concentration ratio in the 170 μg/kg piperine group was significantly lower than that in the other groups (P<0.05), while the AUC0-12 h of brain/plasma concentration ratios in the 5 mg/kg piperine group and the verapamil group were not signiifcantly different from those of untreated mice. Conclusion: Piperine (170 μg/kg) may induce P-glycoprotein expression in the blood-brain barrier, while piperines at 5 mg/kg has no influence on P-glycoprotein expression in the blood-brain barrier.

OBJECTIVETo compare the dissolution properties of Ginseng micropowder and common powder in vitro and investigate the effect of micronization on dissolution of Ginseng.

METHODSFive ginsenosides including Rg1, Re, Rf, Rb1, and Rb2 were determined by high performance liquid chromatography, and the dissolution curves of Ginseng micropowder and common powder were drawn.

RESULTSThe dissolution rates of ginsenosides from micropowder exceeded 90% within 5 min, significantly greater than that from common powder. But when the powders were packed in tea bags, the dissolution rates of ginsenosides were higher from common powder than from micropowder.

CONCLUSIONMicronization treatments can promote dissolution of ginsenosides from Ginseng.
