In recent years, according to the etiology and pathology researches of slow transit constipation (STC) STC is considered as a kind of "enteric neuropathy", indicating it is a kind of disease caused by abnormity of the enteric nervous system (ENS). Through reviewing the mechanism of acupuncture to regulate STC, it is found out that there is a close relationship between acupuncture regulating STC and ENS. Through various channels including ganglion cells, nerve plexus, neurotransmitter and TRPV1 (the primary sensory neurons receptor of the ENS) of the ENS, acupuncture is likely to make comprehensive adjustment on STC.

Objective:To establish a method for the determination of atractylodin, magnolol and honokiol in Xiangshapingwei pills by GC. Methods:An HP-5 column (30 m × 0. 32 mm × 0. 25 μm) with an FID detector was used, and the flow rate of the carrier gas (N2) was 2. 0 ml·min-1. The column temperature was raised by program: the initial temperature was 100℃ and maintained for 7 min, and then raised to 250℃ at the rate of 20℃·min-1 and kept for 10min. The inlet temperature was 300℃ and the detector tem-perature was 300℃. The injection volume was 1 μl and the split ratio was 20∶ 1. Results:The linear range of atractylodin, magnolol and honokiol was 4. 264-85. 280 μg·ml-1(r=0. 999 7), 9. 856-197. 120 μg·ml-1(r=0. 999 5) and 10. 040-200. 800 μg·ml-1 (r=0. 999 6), respectively. The average recovery wsa 98. 2%, 98. 6% and 99. 3% with RSD of 1. 5%, 1. 5% and 1. 9%, respec-tively (n=6). Conclusion:The method is simple, accurate and reliable, which can be used for the quality control of Xiangshaping-wei pills.

Objective: To explore the relationship between ambulatory arterial stiffness indexes (AASI), AASI-blood pressure variability (AASI-BPVR) and left ventricular mass index (LVMI) left atrium diameter (LAD) in patients with hypertension.
Methods: A total of 286 hypertensive patients were enrolled in this study. The AASI, AASI-BPVR were calculated from 24-hour ambulatory blood pressure monitoring. Left ventricular internal dimension in diastole (LVIDd), interventricular septal thickness in diastole (IVSd), posterior wall thickness in diastole (PWd), LAD were detected by echocardiography and LVMI, relative wall thickness (RWT) were calculated. The fasting blood glucose, blood lipids were examined. According to 24 h AASI, the patients were divided into 2 groups, Group A, the patients with AASI > 0.51, n=133 and Group B, the patients with AASI ≤ 0.51,n=153. Pearson and multi regression analysis were conducted to analyze the relevant correlations.
Results: Group A had increased LVMI than that in Group B,P<0.05, the left ventricular masses were similar between 2 groups,P=0.384. Pearson correlation analysis indicated that LVMI and LAD were not related to arterial stiffness index, the coefifcient between 24 h-AASI and LAD was atr=0.111,P=0.057.
Conclusion: AASI and AASI-BPVR were not the independent factors for left ventricular hypertrophy and left atrial enlargement, therefore, they were not the predictors for cardiac damage in patients with hypertension at present time.

Objective To study the features and differences of electromyography of diabetic polyneuropathy (DPN) and alcoholic peripheral neuropathy (APN ), and to provide reference basis for the clinical application of electromyography.Methods 58 patients with DPN and 30 patients with APN were used as subjects. Nerve conduction studies (NCS)and sympathetic skin response (SSR)were performed in the patients, all data were analyzed.Results In the patients with DPN, the abnormalities of NCS and SSR were increased with the prolongation of the time diabetes,and the abnormality of SSR was higher than that of NCS(P<0.05).In the patients with APN, both demyelination and axonal loss in motor and sensory nerves were significantly involved, and the abnomalities of NCS and SSR were higher than those of the DPN patients (P<0.05 or P<0.01);but the proximal nerves were just involoved mildly. Conclusion Both DPN and APN have characteristic electrophysiological features.Early electromyography is useful for the early diagnosis of DPN and APN.According to the electrophysiological features of DPN and APN,the reason of peripheral neuropathy in the patients who have diabetes mellitus and alcoholism could be differentiated.

The study was made on 3H-leucine incorporation into brain of offsprings born by their mothers who were fed in severe iodine deficiency area. Control group received an iodine-supplemented diet (1.7mg KIO3/kg food). Disintegration per minute (dpm) was used as an index to assess the 3H-leu-cine incorporation rate in comparision of the two groups.The results of 3H-leucine incorporation into brain showed that the dpm/mg of brain cortex and cerebellum was significantly lower in experimental group than that of control group at the time of 1-14 hours after injection of the preparation on 11-day offsprings (p

Objective To investigate the association of PPAR gamma Pro12Ala polymorphisms with conroy heart disease(CHD). Methods One hundred eighty impatients were recruited in the study. Venous blood samples were collected after 12 h of fasting from all patients. DNA was extracted and Pro2Ala polymorphism in the PPAR gamma 2 genes was genotyped through the PCR-RFLP. The frequency and distribution of Pro2Ala polymorphism in Chinese Han population with CHD were analyzed. Gensini Score based on coronarography were used to grade the coronary. Results There were a total of 135 CHD patients,of which 52 were affected with single coronary lesion,43 with multi-coronary lesion,and 45 were normal. The frequency of P12/P12, A12/P12 in the coronary lesion group were 92.6% (125/135) and 7.4% (10/135) which were similar to that of 93.3% (42/45) and 6.7% (3/45)(P =0. 548). In the single coronary lesion group, the frequencies of P12/P12 and A12/P12 were 94.0% (42/52)and 9.6% (5/52) ,and 90.0% (36/40) and 10.0% (4/40) in the bi-coronary lesion group,97.7% (42/43) and 2.3% (1/43) in the multi-coronary lesion group,with no significant difference among the three groups( P ＞0.05).There were no significant difference on the frequency of P12/P12 and A12/P12 between various subgroups defined according to Gensini score (P = 0. 246). Compared to the frequency in non-obese, the frequency of A12/P12 were significantly higher in the obese ( P = 0.028 ). In PPAR gamma 2 genes B the Exton BstuI enzyme restriction site genes, BMI,waist-hip ratio and total cholesterol in the carriers of P12A genotype were significantly higher than those in the P12P genotype carriers ( P ＜ 0. 05 ). Conclusions PPAR gamma Pro12Ala polymorphisms might not be associated with CHD in Chinese Han population. The frequency of A12/P12 in obese is significantly higher than that in non-obese. PPAR gamma Pro12Ala polymorphisms might be associated with adiposity and lipid metabolism.

Objective To study the role of different subtypes of PKC in the neurite outgrowth of primary cultured neurons from embryonic rat spinal cord. Methods We observed the expression and distribution of protein kinase C(?、?Ⅰ、?Ⅱ、? subtypes) by using immunohistrochemical technique in the neurite outgrowth of the primary cultured neurons from the embryonic rat spinal cord by means of computer image analysis system to measure the lengths of neurites and the areas of bodies. Results The areas of the cultured neuronal bodies increased and the neurites prolonged while the expression of the four subtypes of PKC gradually increased before 7div(day in vitro )during primary cultured neurons growth. The expression both in bodies and neurites of neurons decreased after 7div and the processes gradually shrinked and at the same time bubbles appeared inside the bodies. Relative assay demonstrated that ?Ⅱ subtype was most relative to the outgrowth of neurites( r =0 73, P
