OBJECTIVETo explore the relationship of Chinese medicine (CM) syndrome with carotid intima-media thickness (CIMT) and endothelium-dependent vasodilatation function (EDVF) in patients with hypertensive disease (HD) for providing an objective basis of syndrome differentiation in HD patients.

METHODSColor Doppler's ultrasound was used to measure the endothelium-dependent flow-mediated dilation (FMD) of brachial artery and carotid intima-media thickness (CIMT) in 60 HD patients (the HD group) and 30 normal controls (the control group). And the relationship of the outcomes with Chinese medicine syndrome types in patients was analyzed statistically.

RESULTSFMD was lower and CIMT was higher in HD patients of all syndrome types than those in the control group respectively (P<0.01). Comparison between patients of different syndrome types showed that FMD was higher in patients of Gan-fire exuberance type and yin-deficiency and yang-hyperaction type than in those of both yin-yang deficiency type and phlegm-dampness stagnancy type (P<0.01, P<0.05), while CIMT in patients of Gan-fire exuberance type was the lowest in all types, and that in yin-deficiency and yang-hyperaction type was lower than in yin-yang deficiency type (P<0.01).

CONCLUSIONCIMT and FMD may be used as a reference index for CM syndrome differentiation in HD patients.

Objective: To observe the effects of acupoint thread-embedding therapy and low-carbohydrate diet therapy on obese patients with food addiction. Methods: Sixty-five eligible patients were randomized into a thread-embedding group of 33 cases and a diet group of 32 cases to respectively receive 12-week treatment. Before treatment, after treatment and at 6-month follow-up, the two groups were observed and compared in terms of body mass (BM), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), body mass index (BMI), body fat rate (BFR), basal metabolic rate (BMR) and Yale food addiction scale version 2.0 (YFAS 2.0). Results: At the end of treatment, there were no significant differences in the general efficacy, and the improvements in BM, BMI, WC, HC, WHR and BFR between the thread-embedding group and diet group (all P>0.05). At follow-up, the thread-embedding group showed more significant improvements in all the aforementioned indicators compared with the diet group except HC (all P<0.05). At the end of treatment and follow-up, BMR and YFSA 2.0 had more significant improvements in the thread-embedding group than in the diet group (all P<0.05). Conclusion: Acupoint thread-embedding therapy can produce significant efficacy in treating obese patients with food addiction; it can improve the food addiction state and work better in maintaining the efficacy compared with low-carbohydrate diet therapy.

OBJECTIVETo investigate the evolution of hepatitis B virus (HBV) quasispecies in one patient during lamivudine (LAM) monotherapy and switching to entecavir (ETV) rescue treatment.

METHODSSerum samples were taken at seven different time points during antiviral therapy (0, 24, 48, 60, 72, 96, 152 weeks, respectively), the HBV DNA polymerase gene was amplified, cloned and sequenced to analyze the amino acid substitutions within HBV DNA polymerase gene and distribution of virus quasispecies. Quantitative detection of the HBV wild strains and total virus was performed by amplification refractory mutation system real-time PCR (ARMS-PCR).

RESULTSThree mutation patterns detected during antiviral therapy in the patient: rtM204V, rtM204V+rtL180M and rtM204I. The HBV quasispecies were found always in dynamic variation. The HBV populations were completely replaced with the LAM-resistant variants when the viral breakthrough was encountered during LAM monotherapy. Interestingly, the wild-type variants presented gradually dominant (79.3%) with the decline of HBV DNA load after switching to ETV rescue administration. ARMS-PCR results showed that the wild-type variants account ed for 68.55% of the HBV populations at baseline and this proportion declined to 0.21% when the viral breakthrough emerged under LAM therapy. The wild-type variants gradually increased from week 24 after switching to ETV rescue therapy and the proportion of HBV wild-type variants in the population fluctuated between 16.01% to 26.93%.

CONCLUSIONSThe distribution of virus quasispecies were always in dynamic variation during sequential therapy with nucleotide analogs in chronic hepatitis B patients. Different patterns of dynamic HBV quasispecies may have different contribution in ETV resistance in LMV refractory patients with ETV administration.

OBJECTIVEAttention deficit hyperactivity disorder (ADHD) is one of the most common behavior disorders in childhood and adolescent. The etiology of ADHD is unknown. The aim of this study was to investigate the relationship between each of the 14 polymorphisms in the five candidate genes and ADHD, and between the combination of some polymorphisms in those genes and ADHD, in attempting to examine whether combinations of genotypes would confer a significant susceptibility to ADHD.

METHODSOne hundred and thirty-nine children with ADHD and one hundred and nineteen normal children were enrolled. Eight single nucleotide polymorphisms (SNP) of three candidate genes were examined with PCR and RFLP techniques. 48 bp VNTR in DRD4 gene was examined with PCR, nondenaturing polyacrylamide gel electrophoresis and silver staining. Five microsatellites (MS) of three candidate genes were examined with genotyping. The relationship between the combinations of 12 polymorphisms and ADHD was examined with logistic regression analysis.

RESULTS1.The frequency of 1065T/1065T genotype and the 1065T allele were significantly higher in ADHD children than that in normal controls (P<0.05). The frequency of -48G/-48G genotype of the A-48G polymorphism of DRD1 gene was significantly lower in ADHD children than that in normal controls (P<0.05). 2. A specific combination of three polymorphisms in the two genes showing an association with ADHD gave a prediction level of 77.5%.

CONCLUSIONSThe T1065G polymorphism in the SNAP-25 may be associated with ADHD. The 1065T/1065T genotype and the 1065T allele may be a risk factor for ADHD. The A-48G polymorphism of DRDI may be associated with ADHD. The -48G/-48G genotype may be a protective factor for ADHD. The specific combination of three sites of SNP in SNAP-25 gene and DRDI gene is found and shows an association with ADHD in 12 polymorphisms of the five candidate genes on glutamatergic/dopaminergic pathway.

BACKGROUND:How to improve the proliferation of human dental pulp stem cells(hDPSCs)in vitro is of great importance in regenerative medicine. OBJECTIVE: To investigate the effect of TAZ, a transcriptional coactivator, on the proliferation of hDPSCs and its potential mechanisms. METHODS:hDPSCs were isolated from human dental pulps and cultured in vitro.The expression of TAZ in hDPSCs was detected by immunofluorescence method. Then, we knocked down the expression of TAZ in hDPSCs, and the proliferation of hDPSCs was measured by MTT and BrdU kit analysis respectively. The levels of CTGF and Cry61, which are the downstream target genes of TAZ, were detected by RT-qPCR and western blot assay. We also investigated the effect of TAZ on the levels of transforming growth factor-β (TGF-β) signaling proteins, Smad3 and Smad 4 by using western blot. RESULTS AND CONCLUSION: TAZ protein was expressed in hDPSCs. After the transfection by siTAZ for 24 hours, the mRNA and protein levels of TAZ were both significantly decreased. After the transfection by siTAZ for 24 and 48 hours, the proliferation of hDPSCs was obviously inhibited. Meanwhile, the mRNA and protein levels of CTGF and Cry61 were decreased by siTAZ transfection. The further research showed that TAZ silence also inhibited the expression of Smad3 and Smad 4, which belonged to the TGF-β signaling pathway. To conclude, TAZ may modulate the proliferation of hDPSCs through regulating the expression of CTGF and Cry61, and TGF-β-dependent signaling pathways may be involved in this regulation.

Objective To develop and explore the effect of model of theory-clinic synchronous practice with double instructors on the nursing undergraduates.Methods Totals of 58 junior students received theory-clinic synchronous practice under the instructions of faculty and clinic instructors.They were investigated with a self-designed clinical teaching satisfaction questionnaire with the dimensions of cases learning (4 items),seminar before and after clinic practice (8 items),practice process (6 items),and its cronbach' s a respectively were 0.75,0.91,0.93.Results Scores of all items and dimensions of satisfaction questionnaire were higher than 4,and the satisfaction score of medium term and practice end were more than 4 too.Scores of dimensions of ‘ cases information',‘ pre and post conferrence' and the total satisfaction score measured at the end of practice were significantly higher than that of medium item (P ＜ 0.05).The score of self-efficacy after practice was significantly higher than that before practice [(3.15 ± 0.42) vs (2.85 ± 0.57)] (t ＝-2.28,P ＝ 0.027).Conclusions The model of theory-clinic synchronous practice with double instructors can improve satisfaction and self efficacy of nursing undergraduates,and will benefit the improvement of comprehensive ability of students.
