Background Cardiomyocytes apoptosis was related to oxidative stress which has been shown to play an important role in ventricular remodeling after myocardial infarction(MI).Probucol is a hypolipidemic and antioxidant agents.Several reports demonstrated its cardioprotective effect after MI.However,the exact effect of probucol on the modification of the apoptosis related gene Bcl-2 and Bax is not clear.Objective To investigate the effects of probucol on mRNA and protein expression of Bcl-2,Bax and oxidative stress in myocardial infarcted rats.Methods Forty-one SD rats that survived 24 h after ligating left anterior descending coronary artery were randomly to receive placebo-saline(5 mL/d,n=20)or probucol(probucol 60 mg/kg?d,n=21).Twelve rats underwent sham operation were served as control(n=12).Six weeks after treatment,hemodynamic pararmeters and left ventricular function were measured with catheterization.Cardiomyocytes apoptosis were determined by TUNEL method.Myocardium mRNA of Bcl-2 and Bax expression levels in the non-infarcted myocardium were as- sessed by RT-PCR.The myocardium protein expression of Bcl-2 and Bax in the non-infarcted myocardium were de- termined by Western blot.Colorimetry was used to determine oxidative metabolism index in myocardium.Results 1)Compared with the sham rats,all MI rats showed marked decrease in Bcl-2 mRNA and protein expression in myo- cardium with increase of Bax mRNA and protein expression and apoptosis index(P

Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

Objective:To analyze the relationship between free androgen index and insulin function in obese young men aged from 20 to 35.Methods:A total of 82 young obese men in Obesity Clinic from February to October 2019 were enrolled in the study. The subjects were divided into 3 subgroups according to free androgen index level tertiles. The blood glucose and insulin levels were tested after oral glucose tolerance test. Homeostasis model assessment for insulin resistance (HOMA-IR), homeostasis model assessment for β cell function (HOMA-β), insulin secretion index, and insulin sensitivity index (Matsuda index) were used to evaluate β cell function in oder to analyze the relationship between free androgen index and insulin function.Results:In young obese men, participants with higher free androgen index levels exhibited less waist circumference, lower body mass index, 1 h postprandial insulin, 2 h postprandial insulin, HOMA-IR level but with a higher total testosterone, sex hormone binding globulin, and Matsuda index level (all P<0.05). There was a negative correlation between the free androgen index and the HOMA-IR ( r=-0.386, P=0.016), and the correlation tended to a linear trend after adjustment for age, sex, body mass index, and waist circumference ( Ptrend=0.034). Free testosterone was positively correlated with Matsuda index ( r=0.280, P=0.004), but the correlation disappeared after adjustment ( Ptrend=0.623). The results of further regression analysis showed that the level of free testosterone index decreased by 14.1% ( OR=0.869, 95% CI0.767-0.984, P=0.028) for each increase of HOMA-IR after adjustment. Conclusion:The level of free testosterone index is a predictor of insulin resistance in obese young men, but the association between this parameter and insulin sensitivity may be caused by obesity.

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.

To evaluate the regulating effect of Buyang Huanwu decoction and its simple prescription (Naojian tablet) on CDK4/Cyclin D1 expression in hippocampus tissues of rats with cerebral ischemia, SD rats were divided into the sham-operation group, the model group, the Buyang Huanwu decoction group (ig, 3.15 g · kg⁻¹) and the simple prescription group (ig, 2.41 g · kg⁻¹). Each group was further divided into five subgroups based on time points after the administration, i. e. 1 d, 3 d, 7 d, 14 d and 28 d, respectively. CDK4/Cyclin D1 expressions of the group at different time points were examined by using immunohistochemistry and real-time qPCR. According to the results, the cerebral ischemia model group showed higher CDK4/Cyclin D1 expression than the sham-operation groups (P < 0.05), suggesting that the cell cycle signal pathway would be activated by the cerebral ischemic injury. Both Buyang Huanwu decoction and simple prescription groups showed significantly lower cyclin expression than the model group at 3 d, 7 d, 14 d, 28 d (P < 0.05), indicating both Buyang Huanwu decoction and its simple prescription could play the neuroprotective effect through the cell cycle signal pathway.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.

METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.

RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.

CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.

Objective To analyze the genetic characteristics and the evolution of the influenza A (H3N2) virus strains circulating in Jiangsu province between 2013 and 2014.Methods This study analyzed thirty-one representative strains of influenza A (H3N2) virus, which were isolated in different regions of Jiangsu province and during different time periods from 2013 to 2014.Results Genetic distances in nucleic acid and amino acid between a strain used for vaccine production (A/Texas/50/2012) and the 31 strains were 0.010 5 and 0.012 4.Similarities between them in nucleic acid and amino acid sequences were 97.9%-99.6% and 97.2%-99.3%.Phylogenetic analysis showed that the hemagglutinin (HA) genes of the 31 strains were divided into three different groups.Three strains isolated in 2013 and three strains isolated in 2014 belonged to Group 1 and Group 2, respectively, while the others belonged to Group 3.Three positive selection sites (237, 366 and 367) in HA protein were observed by REL model.Compared with the strain used for vaccine production, the 31 strains were characterized by amino acid substitutions (N128A/T and P198S/A) in HA protein and all of the mutations located in B-cell epitopes.The total number of mutation sites reached 24.Compared with the A/Texas/50/2012 strain, seven strains presented the glycosylation site 126NWT, and three strains showed disappeared glycosylation sites of 45NSS and 144NNS.Evaluation of vaccine efficacy for A(H3N2) virus strains showed that the vaccine efficacy was not very well.Conclusion The HA gene of A(H3N2) virus had undergone a greater variation and the vaccine efficacy was not very well in Jiangsu province during 2013 to 2014, which made the influenza A(H3N2) virus become the circulating strain.

Objective To evaluate lipid profile and its relationship with body mass index (BMI)in 4784 elderly male subjects. To explore the possibility of using an improvemem of dyslipidemia as an alternative target in the weight control in elderly male population. Methods 4784 elderly male subjects were surveyed with, the measurement of blood lipids and were grouped according to age (60-69, 70-79, 80-96 yrs) and BMI (＜18.5, 18.5-23.9, 24.0-27.9, ≥28.0 kg/m2), respectively.Results The mean levels of TC, LDL-C, TG and HDL-C (mmol/L) were (5.1±0.9)mmol/L,( 3.0±0. 8)mmol/L, (1.5±1.0)mmol/L and (1.3±0. 3)mmol/L, respectively. The prevalence of dyslipidemia was 44.8% (2141 cases) in this population, with specific abnormality rates in TC,LDLC, TG, HDL-C being 10. 4% (497 cases), 9.3% (445 cases), 29.8% (1425 cases) and 19.4% (928cases), respectively. Within all age groups, TG decreased dramatically and HDL-C incre ased with increasing age (P＜0.01), while the 60-69 yrs age group versus other age groups showed a tendency to an increment of TG, and a decrement of HDL-C. (P＜0. 05). Prevalences of overweight and obesity were 46.8% and 15.5% in the elderly male subjects, respectively. The level of TC increased with the increasing BMI, while HDL-C decreased. The differences in TG and LDL-C among various BMI groups were of no statistical significances. High TG and low HDL-C were predominant abnormalities amongst the oldest old, whose lipid profile resembled that of the 70-79 yrs age group.Whilst, the prevalences of overweight and obesity were at the lowest levels of 44.6% (228 cases) and 11.9% (61 cases), respectively. Conclusions High TG and low HDL-C are predominant abnormalities in elderly male subjects. TC level in the current population is higher than that from the national census in 2002. Prevalences of overweight and obesity are close to that in developed countries.TC and LDL-C levels are negatively related to age in the elderly male population, contrasting the correlation between HDL-C and age.
