Objective To investigate the effects and mechanisms of 5-aza-2'-deoxycytidine (5-Aza-CdR) on endometrial cancer cell.Methods In vitro experiments of 5-Aza-CdR were done using human endometrial cancer cell line HEC-1B.Evaluation of cellular proliferation and apoptosis was ascertained respectively using trypan blue exclusion and flow cytometry.RT-PCR and methylation specific PCR(MSP) was done to detect the expression of RASSF1 A mRNA and methylation status of RASSF1 A promoter of HEC-1B cell line.Results (1) The status of cellular growth and apeptosis of HEC-1 B cell line:the growth inhibition effects of 5-Aza-CdR on HEC-1B cell line were both concentration-dependent (P ＜ 0.01) and time-dependent(P ＜0.01),as well as the apoptosis rate of HBC-1-B cell line depended on the dose of 5-Aza-CdR obviously(P ＜0.01).(2)The expression of RASSF1A mRNA of HEC-1B cell line:RASSF1A mRNA was expressed in HEC-1B cell after 5-Aza-CdR treatment,but it was undetectable before the treatment.In the groups with different concentration of 5-Aza-CdR (0.05,0.1,1,5,10 nmol/ml),the expression of RASSF1A mRNA was respectively 0.074±0.004,0.105±0.004,0.167±0.006,0.334±0.005,0.484±0.007,which were remarkably different from the group without 5-Aza-CdR(the expression of RASSF1A mRNA was 0;P ＜ 0.01).(3) The hypermethylation of RASSF1A promoter of HEC-1B cell line:the hypermethylation of RASSF1A promoter was detected in HEC-1B cell line.The status of hypermethylation was decreased after treatment with 5-Aza-CdR of 0.05,0.1,1,5 nmol/ml,meanwhile,both methylation bands and demethylation bands were observed by methylation specific PCR.After the treatment with 5-Aza-CdR of 10 nmol/ml the hypermethylation was absent absolutely.Conclusions (1) In HEC-1B cell line,5-Aza-CdR can inhibit cell proliferation and induce cell apopotosis.(2) 5-Aza-CdR can renew the expression of RASSF1A mRNA of HEC-1B cell line and reverse the hypermethylation of RASSF1A promoter.

Abundant experiences have already been accumulated in treatment of stroke with acupuncture. Development of rehabilitation theory also brings unprecedented opportunity and challenge to acupuncture. Combined with the modern rehabilitation theory and practice, it is very helpful to deepen the understanding on treatment of acupuncture for cerebral apoplexy and enhance the therapeutic effect in clinic by studying the mechanism of acupuncture treatment, opportunity of intervention, selection of acupoints, needling manipulations and quantity of stimulations etc. Through analysis on the necessity and the way of combination of acupuncture and modern rehabilitation, it is concluded that rehabilitation evaluation, rehabilitation phases and obstacle analysis should be taken as references by acupuncturists to reinforce the therapeutic effect and creditability of acupuncture treatment on cerebral apoplexy.

The research on regulation rules of traditional Chinese medicine (TCM) syndrome was the core of TCM syndrome information. It was thought that the constitution identification which provided the technology for evaluating health status was one of the bases in drawing the curve of conditional standard of syndrome. It was fitted and analyzed by the curve of conditional evolution of syndrome through establishing the curve of conditional standard of TCM constitution theory. It was the key technology of realizing the dynamical evaluation of TCM clinical effect.

Objective To investigate the relationship between metabolic syndrome (MS) and early recurrence of benign prostatic hyperplasia (BPH) after prostatectomy in the elderly.Methods A total of 152 men aged 65 to 88 years with prostatectomy for more than 5 years were enrolled from August 2008 to March 2013.Blood pressure,body weight,body height,body mass index (BMI) and international prostate symptom score (IPSS) were detected.Levels of fasting blood glucose (FBG),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),prostate specific antigen (PSA) and maximum urinary flow rate (Qmax) were determined.The correlation of MS-related parameters with prostate volume,IPSS and Qmax were evaluated.Results BPH recurrence rate was significantly higher in patients with MS than without MS (11/26 vs.27/126,x2=12.76,P＜0.001).PSA level,prostate volume and IPSS were significantly higher or larger in the MS group than in the non-MS group [(1.96±0.82)μg/L vs.(1.81±0.90)μg/L,(28.26±5.50) ml vs.(22.38±4.00)ml,(11.12±3.18)vs.(7.11±2.37),F=28.654,44.41,38.56,respectively,P＜0.001],while Qmax value was significantly lower in the MS group than in the non-MS group [(14.77±5.29) ml/s vs.(19.80±4.70) ml/s,F=59.48,P＜0.001].The liner regression analysis showed that in postprostatectomy recurrence group,PV and IPSS had significantly positive correlations with levels of FBG and TG,and BMI (P＜0.05),and had significantly positive correlations with BMI and FBG in non-recurrence group (P＜0.05),while Qmax had a significantly negative correlation with BMI,systolic blood pressure and FBG in the two groups (P＜0.05).Conclusions There is a significant relationship between MS and higher BPH recurrence in elderly patients.

Background Endophthalmitis is a serious infectious eye disease.Efficient drug therapy plays a key role in the early stage.There have been few researches on teicoplanin treating endophthalmitis and pharmacokinetics in ocular tissue.Objective The present study was to investigate the intraocular pharmacokinetic course and feature of intravitreal administration of teicoplanin.Methods Thirty-three Japanese white rabbits were included in this study and randomized into 6 groups.The right eyes of the rabbits were used in experiment.5 g/L of teicoplanin was injected into the vitreous cavity,and vitreous and aqueous humor samples were extracted after 15 minutes,30 minutes,1,2,4,6,12,24,48,96 and 192 hours,and the concentration of teicoplanin was determined by bioassay.Results The logarithmic value of the concentration of teicoplanin was raised with the increase in the bacterial inhibition zone diameters,of which the equation of the regression curve was Y =0.174X-0.813(R2=0.999).A good linear relationship was presented within 1.0-80.0 mg/L.Single intravitreal injection of teicoplanin was compliant with the two-compartment model.Moreover,the distribution phase Tα1/2 and elimination phase Tβ1/2 of vitreous were 1.68 and 152.15 hours,separately.And Tα1/2 and Tβ1/2 of the aqueous humor were 2.83 hours and 70.56 hours,individually.The peak teicoplanin concentrations in the vitreous and aqueous humor were(358.47±21.53)mg/L and(102.17±9.54)mg/L at 1 hour,respectively and remained at(4.38±0.68)mg/L and(2.38±0.38)mg/L,respectively 192 hours later.Conclusions Intravitreal injection of 0.5 mg of teicoplanin can remain therapeutic concentration for a long time in the vitreous and aqueous humor.

Objective To examine the expression of angiotensin Ⅱ (Ang Ⅱ) receptor subtypes in human left and right atrial tissue in atrial fibrillation underlying rheumatic heart disease. Methods Atrial tissue samples were obtained from 39 patients with rheumatic heart disease, 25 with atrial fibrillation(AF) and 14 with sinus rhythm(SR) during open heart surgery. AT1 and AT2 mRNA levels were measured with semi-quantitative reverse transcription polymerase chain reaction techniques. AT1 and AT2 protein levels were measured with immunohistochemical techniques. Results Compared with that of the SR group, left atrial inner diameter was significantly increased in the patients of the AF group. The AT1 mRNA and protein levels in the LA significantly increased in patients with AF compared with those in patients with SR (P < 0. 05), whereas AT2 mRNA and protein were not significantly altered. Investigations of Ang Ⅱ receptor subtypes' mRNA and protein levels in the RA did not exhibit any significant changes either in AT1 or AT2 in patients with AF and SR. Conclusions AF is associated with an up-regulation of AT1 in LA, but does not appear to influence the AT2 expression. This may indicate a possible pathophysiologie role for renin-angiotensin system in the development of AF. The series of effects mediated by ATI activation may be one of the molecular mechanisms involved in the process of atrial remodeling.

OBJECTIVETo explore a more effective therapy for treatment of hyperemesis gravidarum.

METHODSNinety cases were randomly divided into an acupuncture group, a western medicine group and a Chinese medicine group, 30 cases in each group. They were treated with same supplement of water and electrolyte, with acupuncture at Dazhu (BL 11), Shangjuxu (ST 37), Neiguan (PC 6), Gongsun (SP 4), etc. added in the acupuncture group, with oral administration of Luminal 30 mg thrice each day added in the western medicine group and with oral administration of Chinese herbal decoction according to syndrome differentiation of TCM added in the Chinese medicine group. The therapeutic effect, ketone bodies, carbon dioxide combining power (CO2-CP) and electrolyte imbalance situation in all the groups were observed.

RESULTSAfter treatment for 7 days, the total effective rate of 96.7% in the acupuncture group was better than 46.7% in the western medicine group and 60.0% in the Chinese medicine group (both P < 0.01). There were significant improvements in ketone bodies in the acupuncture group compared with those before treatment and those in the western medicine group (both P < 0.05), and improvements in CO2-CP and electrolyte imbalance in all the groups were following the recovery of disease.

CONCLUSIONAcupuncture has rapid and obvious therapeutic effect on hyperemesis gravidarum without adverse reactions.

Aim To study the effects of prenatal hy-poxia on the risk of fatty liver disease to search the drug targets .Methods Intrauterine hypoxia rats model was established .The bodies and livers of fetal rats of 21 days, and adult offspring rats of 5 months with and without anoxic treatment were all weighed .The liver index was calculated and the concentrations of renin-angiotensin system components in circulation system and livers of offspring rats were measured .Results The weight of the bodies , livers and index of liver weight to body weight ( liver index ) were significantly decreased in the PH group compared with the normal group.These differences disappeared in adulthood . However, the liver index of adult offsprings in the PH group after hypoxia stress for 7 days was significantly increased compared with that of adult offsprings in nor-mal group.There were no significant differences in the concentrations of AngⅠ, AngⅡ and ACE in plasma and livers between the two groups of fetal rats and the two groups of adult offspring rats separately .The con-centrations of AngⅡ in the livers of adult rats in PH group were significantly higher than those in normal group.The concentrations of AngⅠ in livers and the concentrations of AngⅡ in plasma and livers in the group treated with hypoxia stress for 7 days were signif-icantly higher than those without hypoxia stress .The concentrations of ACE in livers and the concentrations of AngⅡ in plasma and livers in PH adult offsprings were significantly higher than those of normal adult off-springs .Conclusion PH can induce the increase of RAS content in the livers of fetus and adult rats , RAS is more likely to be activated after hypoxia stimulation in the following adulthood .PH is a potential mecha-nism that mediates offspring susceptibility of fatty liver .

Objective The purpose of the study was to compare the P63 expression in non-small cell lung cancer (NSCLC) between Xuanwei and other regions, and to investigate the relationship of P63 expression and biological behavior. Methods Immunohistochemical method was used. Results The results indicated that the expression of P63 in lung squamous cell carcinoma was extraordinarily high. P63 was related to the TNM staging system,tissue differentiation degree and lymph node metastasis,but not related to gender. In NSCLC,there was no significant difference of the P63 positive expression rate in the same pathological types, staging, tissue differentiation degree, lymph node metastasis and gender between Xuanwei and other regions. It indicated that the expression of P63 was not the reason why it was high incidence of lung cancer in Xuanwei region.
