Objective To evaluate the influence of metabolic syndrome(MS) on the left ventricular hypertrophy in non-diabetic hypertensive patients.Methods A total of 321 essential hypertensives were included in which 134 patients were diagnosed as MS(EH+MS),187 patients with hypertension alone(EH) as controls.Left ventricular mass index(LVMI) and relative wall thickness(RWT) were determined by echocardiography.Results Compared with hypertension alone(EH) patients,hypertensive patients with MS(EH?MS) were shown to have greater end-diastolic left ventricular internal dimension(LVEDd),end-diastolic interventricular septum thickness (IVSD),end-diastolic posterior wall thickness(LVPWd) and left ventricular mass indexed(LVMI)(P0.05).Left ventricular mass index(LVMI) was strongly related with waist circumstance(r=0.692,P

Objective To observe the curative effect and safety of Xiaoer zhixie decoction in treatment children with infectious diarrhea.Methods 84 cases with infectious diarrhea were randomly divided into 3 groups (positive control group,Xiaoer zhixie decoction group and control group).The control group (n =27) was treated with conventional therapy such as nutritional therapy.The Xiaoer zhixie decoction group (n =28) was given Xiaoer zhixie decoction through clysis.Positive control group(n =29) was treated with oral.Smectite powder.The therapeutic effect of 3 groups was observed during the 3rd day,the 5th day and the 7th day after treatment.Results The total effective rate of control group was 40.7％,positive control group was 79.3％ and Xiaoer zhixie decoction group was 78.6％ after 3 days treatment.Compared with control group,positive control group and Xiaoer zhixie decoction group achieved obvious effect(P ＜0.01).The positive control group and Xiaoer zhixie decoction group did not have significant difference(P ＞0.05).Conclusion The clinical effect of Xiaoer zhixie decoction in treatment children with infectious diarrhea is significant.

OBJECTIVETo investigate the permance index ofof portable X-ray fluorescence spectrometer in the determination of lead on filter membrane and to provide data for the determination of lead in workplace air.

METHODSIrradiated with X-ray, the lead would emit specific X-ray fluorescence during the process from the excited state back to the ground state. Rapid determination of lead was completed using fluorescence energy and wave length for qualitative analysis and fluorescence intensity for quantitative measurement. Under set conditions, a series of customized calibration samples were measured to create a standard curve for quantitative analysis of lead on filter membrane.

RESULTSThe regression equation obtained using a portable X-ray fluorescence spectrometer to determine the lead on filter membrane was y=0.004x-0.182 (r2= 0.9999). The linear range was 0.00 -10.40 mg/m3, the minimum detectable concentration was 0.53 µg/m3, and the minimum quantifiable concentration was 1.76µg/m3. The relative standard deviation (RSD) of within-run precision of samples with different concentrations was 0.48%-6.22%, the RSD of between-run precision was 2.51%-5.09%, and the degree of accuracy was in the calibration range of standard samples.

CONCLUSIONPortable X-ray fluorescence spectrometry is a simple, rapid, repeatable, and accurate method for the determination of lead on filter membrane.

Objective:To observe the changes of visual evoked potential(VEP)in diabetic rats and the influence of nerve growth factor(NGF)and aminoguanidine(AG)on VEP.Methods:Diabetes was induced in adult male Wistar rats with streptozotocin(STZ).Rats were divided into normal control group(CON),diabetes model group(DM).NGF-treated group(D +N)and AG-treated group(D+A).VEP was measured during the 3~(rd)month,6~(th)month,9~(th)month,and 12~(th)month.Results: Compared with the CON group,all rest groups had longer latencies and lower amplitudes(P

Objective To investigate the effects of adrenocorticotropic hormone (ACTH)combined with Huaiqihuang on hypothalamic pituitary adrenal (HPA) in rats. Methods Fifty rats were randomly divided into five groups according to the random number table method:normal control group (group A), prednisone group (group B), Huaiqihuang group (group C), ACTH group (group D) and combined treatment group (group E) with 10 rats in each group. Rats in group B, C, D and E were gavaged by acetic acid prednisone water solution 12.5 mg/(kg · d) for 4 weeks to establish HPA axis suppression model. Group A was given distilled water 10 mL/(kg·d) as control. Rats in group C and E were gavaged with Huaiqihuang 5 g/(kg·d) 30 minutes after intragastric administration of prednisone acetate. At the third week of the experiment, group D and E were subcutaneous injected with ACTH 200 μg/(kg·d). The serum cortisol levels were measured respectively at the start of the ex?periment, 2 weeks and 4 weeks of experiment. Animals were sacrificed at the end of the experiment, and then weights of the pituitary, adrenal glands and the viscera index were calculated. The pathological changes of the pituitary and adrenal glands were observed by HE stainning. Results After 2 weeks, the serum cortisol levels were significantly lower in group B, C, D and E than those of group A (P<0.05), suggesting that the model was successful. After 4 weeks, the serum cortisol levels were significantly higher in group C, D and E than those of group B (P<0.05), and between the treatment group the value was group E>group D>group C (P<0.05). At the same time, the weights of pituitary and adrenal gland and the viscera in?dex were higher in the three groups than those of B group (P<0.05). The HE staining showed that there were no significant changes in the distal part of the pituitary gland in five groups. The adrenal cortex zona was thinning and the structure was dis?ordered in group B. There were different degrees of hyperplasia in group C, group D, and group E, which was the most obvi?ous in group E. Conclusion ACTH combined with Huaiqihuang can promote adrenal cortex zona hyperplasia and cortisol secretion, which reduces the glucocorticoid induced inhibition of HPA axis in rats.

Objective:To observe effects of wrist-ankle acupuncture (WAA) onβ-endorphin (EP), nitric oxide (NO) in uterus tissue and prostaglandin F2α (PGF2α), substance P (SP) in serum of rats with primary dysmenorrhea. Methods:A total of 45 non-pregnant Wistar rats were randomly divided into a control group, a model group and a WAA group, 15 rats in each group. Rats in the model group and the WAA group received continuous abdominal subcutaneous injection of Diethylstilbestrol to establish dysmenorrhea rat models. On the first day after modeling, rats in the WAA group began to receive acupuncture on Point Lower 1 and Point Lower 2, once a day for 10 d. The control group and the model group didn’t receive any treatment. Writhing latencies and frequencies were recorded.β-EP and NO in uterus tissue homogenates and PGF2α, SP in serum were detected. Results:In the model group,β-EP and NO levels were the lowest among the groups, the serum PGF2α level was the highest, and serum SP level was the lowest. These measurements showed significantly difference between the model group and the control group (P<0.05). PGF2α in the WAA group was lower than that in the model group;β-EP, NO and SP levels were higher than those in the model group, with inter-group statistically significant differences (P<0.05). Conclusion: WAA may achieve analgesic effect through decreasing PGF2α, increasingβ-EP, NO and SP to relieve uterine cramps, increase blood flow and promote functional improvement.
