It is an important measure in improving the practical teaching quality at Chinese westem medical colleges to strengthen the training practice of part-time assistant teachers in clinical teaching bases. To establish a good training model,we should take into consideration its operability and practicability, as well as the positivity of the teachers.The key to making the training succeful is to ascertain the direction and contents, to set up an instructors' team, and to make a specific training plan.

Objective To investigate the organophosphorus pesticide residues in vegetables and fruits in Shnxi area so as to take preventive measures to minimize food contamination. Methods A total of 140 samples of vegetables and fruits were obtained randomly from the local market in Shnxi area. Eight organophosphorus pesticides were analyzed by gas-chromatographic method. Results The incidence of organophosphorus pesticide residues in vegetables and fruits were 20% and 1.7%, respectively. The mean level of parathion in vegetables and dimethoate in fruits were 6.22?g/kg and 3.02?g/kg, exceeding their MRLs. Conclusion There is a misuse of organophosphorus pesticides in Shnxi area and routine monitoring is necessary to reduce food contamination before entering market.

Objective To explore the impact of folate on MeCP2 expression and cervical cancer cells growth.Methods Cervical cancer cell lines Caski (HPV16-positive) and C33A (HPV-negative) were treated with different concentrations of folate.MTT,flow cytometry,Western blott and real-time PCR were used to detect the cells’ viability,apoptosis,the expression of MeCP2 protein and mRNA expressions respectively.Results The inhibitions of both cell growth were upgraded with the folate concentration increasing.The differences were significant between the experimental groups and the control group.With increasing of folate concentration,apoptosis ratio of C33A and Caski increased gradually (C33A:r =0.965,P ＜ 0.001; Caski:r =0.973,P ＜ 0.001) and the expression of MeCP2 protein downgraded gradually,presenting significantly negative correlations between them (C33A:r =-0.952,P ＜ 0.001; Caski:r =-0.947,P ＜ 0.001).There was significantly difference for mRNA expression in different concentration groups of Caski and C33A (C33A:F =77.041,P ＜ 0.001; Caski:F =59.885,P ＜ 0.001).In the same concentration group,the expression of MeCP2 protein and mRNA were higher in Caski than that of C33A,and the difference was significant in the concentration of 500 μg/ml group.There was a negative correlation between the expression of MeCP2 protein and cells’ apoptosis ratio (C33A:r =-0.970,P ＜ 0.001; Caski:r =-0.93,P ＜ 0.001).Conclusion Folic acid can inhibit the growth of cerical cancer cells,promote apoptosis and reduce the expression of MeCP2.The aberrant high-expression of MeCP2 can inhibit apoptosis of Caski and C33A.

Methods From June 1st ,2007 to June 1st ,2011 ,the patients received EST treatment were followed up , the follow‐up time was three to seven years .A total of 2 738 patients were successfully followed up , including 24 patients with two or more than two times of recurrent bile stone after EST who were enrolled in multiple recurrence group .One hundred patients without recurrence were randomly selected by table of random number as control group .The clinical data of two groups were compared by t test or Chi‐square test .The factors were analyzed with multivariate Logistic regression analysis and try to find out the risk factors of multiple recurrence .Results The comparative analysis between two groups showed that the three factors of juxtapapillary duodenal diverticula [17 .0% (17/100 ) vs 41 .7% (10/24 )] ,history of biliary tract surgery [13 .0% (13/100) vs 45 .8% (11/24)] and the angle enclosed between the horizontal portion of the CBD and the horizontal plane (angleofbile duct) less than 45° [2 .0% (2/100) vs 20 .8% (5/24)] were statistically significant (χ2 = 6 .914 、13 .37 、9 .595 ,all P < 0 .01 ) . Furthermore , logistic regression analysis indicated that juxtapapillary duodenal diverticula (B = 1 .421 ,OR = 4 .142 ,P = 0 .01) , history of biliary tract surgery (B = 1 .612 ,OR = 5 .011 ,P= 0 .004) and the angle of bile ductless than 45° (B= 2 .661 ,OR= 14 .31 ,P= 0 .005) were risk factors of multiple recurrence .Conclusion Juxtapapillary duodenal diverticula , history of biliary tract surgery , and the angle of bile duct less than 45° are independent risk factors of multiple recurrence of CBD stones .

This study aims to detect early changes of kidney in patients with primary hypertension by 3.0 T functional magnetic resonance imaging (fMRI). 26 patients with primary hypertension (hypertension group) and 33 healthy volunteers (control group) underwent conventional and functional magnetic resonance scans, which included blood oxygen level-dependent (BOLD) MRI, diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). We measured renal cortical thickness (CT), parenchymal thickness (PT), and functional values of renal cortex and medulla including R2* value, apparent diffusion coefficient (ADC) value and fractional anisotropy (FA) value in each group, and then calculated the cortical/parenchymal thickness ratio (CPR). Compared with those in the control group, CT and CPR in hypertension group were larger (P < 0.01), cortical and medullar R2* values increased (P < 0.01) whereas medullar FA values decreased (P < 0.05). It could be well concluded that noninvasive 3.0 T functional MRI would have important clinical significance in identifying early abnormalities of kidney in hypertension patients.

PARP [poly(ADP-ribose)polymerase] represents a novel potential target in cancer therapy. It is involved in a DNA repair process by catalyzing the transfer of ADP-ribose units from NAD to a number of its substrate proteins. In this work, a series of novel azaindole derivatives was designed and synthesized. Moreover, 16 target molecules were screened and 8 compounds displayed inhibitory activity against PARP-1. It has been demonstrated that these azaindoles bearing cycloamine substituents at 2-position were active to both PARP-1 and PARP-2.

Objective:To observe the therapeutic effect of vibrating the abdomen on anorexia model rats,as well as its effects on cholecystokinin octapeptide(CCK-8)and motilin(MTL)in the peripheral blood. Methods:Forty young rats were randomly divided into a normal group(n=10)and a modeling group(n=30).Rats in the normal group were fed common feed.The anorexia model was established by the etiological simulation method in the modeling group,and these rats were further randomly divided into a drug group,a vibrating abdomen group,and a model group 3 weeks after the anorexia model was induced,with 10 rats in each group.The drug group was given Jian Wei Xiao Shi Pian by intragastric administration at a dose of 0.72 g/(kg·bw)(0.72 g drug was dissolved in 10 mL purified water).The normal group and the model group were given purified water once a day in the morning.The vibrating abdomen group was treated with vibrating the abdomen once a day for 21 times.The body mass,food intake,serum CCK-8,MTL,gastrin(GAS),neurotensin(NT)levels,and the intestinal propulsion rate of rats in each group were measured. Results:Compared with the model group,the body mass,food intake,serum MTL and GAS levels,and the small intestine propulsion rate increased significantly,and the serum CCK-8 and NT levels,the gastric residual rate decreased significantly in the vibrating abdomen group and the drug group(P<0.05).There were no significant differences between the vibrating abdomen group and the drug group(P>0.05). Conclusion:Vibrating the abdomen increases the food intake and body mass of anorexia model rats,reduces the residue of gastric contents,improves the small intestine propulsion rate,and therefore has a good therapeutic effect on anorexia.The mechanism may be related to inhibiting the secretion of CCK-8 and NT in plasma and promoting the release of MTL and GAS in serum.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.
