OBJECTIVE@#To compare the curative effect on diarrhea-predominant irritable bowel syndrome (IBS-D) between acupuncture for regulating @*METHODS@#A total of 231 patients with IBS-D were randomized into an acupuncture group (154 cases) and a western medication group (77 cases) at the ratio of 2 to 1. In the acupuncture group, acupuncture was applied to acupoint regimen for regulating @*RESULTS@#After treatment and in follow-up, the total scores of IBS-SSS in the patients of the two groups were all reduced as compared with those before treatment (@*CONCLUSION@#Acupuncture for regulating

Bidirectional regulation of acupuncture: a subgroup analysis of multicenter randomized controlled trial of acupuncture with / 中国针灸

OBJECTIVE@#To explore the bidirectional regulation of acupuncture based on a subgroup analysis of multicenter randomized controlled trial of acupuncture with @*METHODS@#A total of 519 patients were included in the analysis, including 137 patients with constipation type irritable bowel syndrome (IBS-C) (92 cases in the acupuncture group and 45 cases in the polyethylene glycol [PEG] group), and 382 patients with diarrhea type irritable bowel syndrome (IBS-D) (252 cases in the acupuncture group and 130 cases in the pinaverium group). The patients in the acupuncture group were given acupuncture at Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Shangjuxu (ST 37), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) once every other day, 3 times a week. The patients in the PEG group received polyethylene glycol 4000 powder orally, and the pinaverium group received pinaverium bromide tablets orally. All were treated for 6 weeks. The IBS symptom severity score (IBS-SSS) was assessed at baseline, treatment period (2, 4, 6 weeks of treatment) and 12 weeks of follow-up, and the IBS quality of life (IBS-QOL) score was evaluated at the baseline period, 6 weeks of treatment and 12 weeks of follow-up.@*RESULTS@#The total IBS-SSS scores of the two groups of IBS-C patients at 2, 4, 6 weeks of treatment and follow-up of 12 weeks were lower than those in the baseline period (@*CONCLUSION@#Acupuncture with

A correlation analysis of HBV-DNA load levels between in perinatal mother's serum and neonatal cord blood / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the correlations of hepatitis B virus markers and hepatitis B virus -DNA vectors in blood between women in perinatal period and cord blood, and to assess the risk of HBV infections status in pregnant women to intrauterine fetal infective.</p><p><b>METHODS</b>We selected 612 pregnant women who decided to delivery in hospital, in compliance with the principles of informed consent. According the difference of hepatitis virus serological markers existing in pregnant women, samples were divided into six groups. We used enzyme-linked immunosorbent assay to detect hepatitis virus serological markers, existing in serum of mother and cord blood. Real-time fluorescence quantitative PCR was supplied to test HBV-DNA load levels in these two kinds of biological specimen.</p><p><b>RESULTS</b>In group A, hepatitis B virus "big 3 positives" or 1,3 positive 149 lying-in woman examples, two positive rates of HBV-DNA about pregnant women and cord blood are 99.33% and 32.21%; in group B, positive rates of HBV-DNA in two kinds of specimen are 20.00% and 3.08%; in group C and D, two positive rates are and the average contents of HBV-DNA, the results as mentioned in each group respectively are 65.52%, 12.07% and 13.56%, 1.69% respectively. Control group is group E, 86 lying-in woman examples and the detecting results orderly are 1.16%, 0. There was a significant difference in positive rate of HBV-DNA in cord blood between group A and group B subgroups (chi2 = 54.09, P < 0.01). There is significant positive correlation between HBV-DNA vectors existing in mother's serum and the positive rate of HBV-DNA in cord blood. Hepatitis B virus the mother blood " big 3 positives " is the umbilicus blood HBV-DNA 6345 times that carries quantity in average.</p><p><b>CONCLUSION</b>(1) During the perinatal period, along with the HBV-DNA load levels arising of pregnant women, the risk of HBV infections status in pregnant women to intrauterine fetal infective increased. (2) Suggested to develop the compound pattern human hepatitis B immunoglobulin: Increase the composition of efficient price HBeAb-can be combinated HBeAg, HBsAb can be combinated HBsAg, strengthen the hinderance and break hepatitis B virus disseminate. (3) Our government should strengthen the propaganda of hepatitis B virus education. Establish and perfect to surround and produce the system of health protection.</p>

Progress on epigenetics applications in forensic science / 法医学杂志

Epigenetics is the study of heritable changes in gene expression other than changes in the underlying DNA sequence. Such changes include DNA methylation, histone modification, chromatin remodeling, genomic imprinting, X chromosome inactivation and non-coding RNA regulation. Recent progresses on epigenetics open new possibilities in tackling these challenging problems in forensic science, including identification of fetal paternity testing in embryonic period, determination of the necessary allele in paternity testing, discrimination of identical twins, origination analysis of micro tissue, verification of forged DNA. This review focuses on epigenetics concept and its latest application in the field of paternity testing, age estimation, discrimination between the twins, identification of tissue of origin, and estimation of postmortem interval.
