ABSTRACT

Rhei Radix et Rhizoma was first recorded in Shennong Ben Cao Jing, with a wide range of pharmacological activities. Autoimmune disease is a kind of disease that damages the tissue structure and function of immune cells and their components due to the impairment of immune tolerance function, including atherosclerosis, multiple sclerosis, gout, rheumatoid arthritis, autoimmune thyroiditis, ulcerative colitis, type 1 diabetes and IgA nephropathy. In recent years, clinical and experimental studies show that Rhei Radix et Rhizoma has potential therapeutic effects on autoimmune diseases. Under the guidance of the theory of traditional Chinese medicine, this paper reviews therapeutic and intervening effects of Rhei Radix et Rhizoma and its main active ingredient anthraquinone on autoimmune diseases. It also puts forward new study directions in view of the existing problems in studies of rhubarb and its anthraquinone, with the aim to provide reference for clinical treatment and scientific studies of effect of Rhei Radix et Rhizomaon autoimmune diseases.

ABSTRACT

Intestinal Peyer's patches (PPs) are local immune tissues of the intestine, which are considered to be the main induction site of the intestinal mucosal immune response, and closely related to immune-related refractory enteropathies, such as ulcerative colitis and Crohn's disease. In recent years, more and more scholars have tried to find a new breakthrough for treating refractory enteropathies with a limited efficacy of clinical interventions through in-depth study of the relationship between PPs and enteropathy. Traditional Chinese medicine (TCM) polysaccharides are considered to be a key component for immune regulation with TCM. Modern studies show that TCM polysaccharides have a significant positive intervention effect on the structure and function of PPs, with good development prospects. Based on this, this paper focuses on PPs and intestinal-related diseases, and systematically introduces the physiological structure of PPs and their drug delivery mechanism, and summarizes the interactions of PPs with effect on immune-related enteropathies, analyze of current studies and prospects of effect of TCM polysaccharides in intervening intestinal disease and its dysfunction by regulating PPs, with the aim to provide new strategies for basic studies and clinical treatment of immune-related refractory enteropathies from the perspective of PPs, and new ideas for basic studies and clinical studies on effect of TCM polysaccharides in intervening enteropathies.

ABSTRACT

Objective To explore the risk factors and the rate of HBV vertical transmission from HBsAg-positive couple to their infant.Methods 46 families who had antenatal examination at Fujian Provincial Maternal and Child Health Hospital during August 2010 and November 2011 were chosen as research object.Cord blood was sampled after delivery for HBVM and HBV-DNA quantification.Those with HBV-DNA load ≥5 × 102 copies/ml were involved in the case group while those having <5 × 102 copies/ml were chosen as controls.Results The average positive rate of neonatal cord blood HBV-DNA was 45.7% (21/46),while the positive rates of cord blood HBsAg and HBeAg were 34.8%(16/46) and 23.9% (11/46) respectively.The positive rates of maternal serum HBV-DNA and paternal serum HBV-DNA were 52.2% (24/46) and 69.6% (32/46) respectively,with the positive rate of couple serum HBeAg as 39.1% (18/46) and 32.6%(15/46) respectively.Results from univariate analysis showed that hepatitis B surface markers,serum HBeAg-positive,serum HBV-DNA positive,and serum HBV-DNA load of the couples were risk factors to the HBV vertical transmission(x2=8.731,8.414,8.932,9.663,10.823,3.962,13.638,36.501 ;P<0.05).Data from the multivariate analysis showed that maternal serum HBV-DNA positive and paternal serum HBV-DNA load were risk factors to the HBV vertical transmission [OR= 17.6 (1.3-238.4) ;OR = 3.5 (1.6-7.6)].Serum HBV-DNA loads of the couples were positively correlated with the cord blood HBV-DNA load,while the load levels of the couple' s serum HBV-DNA were higher than cord blood HBV-DNA.There appeared dose-response relationship between couple' s serum HBV-DNA load level and the cord blood HBV-DNA load level.Results from the analysis of ROC curve showed that both maternal serum HBV-DNA load level (103 copies/ml) and paternal serum HBV-DNA load level (104 copies/ml) were demarcation points to better forecast the occurrence of vertical transmission of HBV,because there showed higher sensitivity and specificity for the forecasting process.Neonatal outcomes showed no significant difference between the case group and the control group.The negative conversion rate became 15.0% (3/20) when the HBV-DNA positive infants were followed up for 7 months.Conclusion Both maternal serum HBV-DNA positive and paternal serum HBV-DNA load were risk factors of HBV vertical transmission.When the maternal serum HBV-DNA load appeared >103 copies/ml and paternal serum HBV-DNA load > 104 copies/ml,the rate of HBV vertical transmission would increase.

ABSTRACT

Objective To study the influence of HBV-DNA with different load levels of HBsAg-positive among fathers on the rate of neonatal cord blood HBV-DNA.Methods Using HBsAg and HBV-DNA as screening indicators for pregnant women and their husbands from an obstetric clinic.161 pregnant women whose HBsAg and HBV-DNA were negative,but HBsAg was positive among their husbands and their newborns,were selected.Blood samples from those pregnant women,their husbands and their newborns were collected to detect the related indicators.Using ELISA to detect hepatitis B virus markers(HBVM),and FQ-PCR to detect the levels of HBV-DNA load.According to neonatal cord blood HBV-DNA detection guideline,newborns with cord blood HBV-DNA positive were selected as cases,others as controls.Results(1)Result of the study showed that there was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive rates in newborns(trend χ~2=64.117,P=0.000).The rate of vertical transmission of HBV from HBsAg-positive father to infant in the paternal serum HBV-DNA>1.0×107 copies/ml group was significantly higher than HBV-DNA<1.0×107 copies/ml group(χ~2=71.539,P=0.000).(2)There was a positive rank correlation between semen positive HBeAg and vertical transmission of HBV from HBsAg-positive father to infant(χ~2=6.892,P=0.009).Conclusion There was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive in newborns.Paternal serum HBV-DNA≥1.0×107 copies/ml and with HBeAg positive status were risk factors of vertical transmission of HBV from HBsAg-positive father to infant.

ABSTRACT

Objective To explore the role of maternal physiology, mentality and prenatal health care on low birth weight (LBW). Methods A LBW-small for gestation age (SGA)-control group retrospective study was conducted based upon a population of infants born from November 2004 to June 2006. 896 cases involved in this study were entirely under voluntary participation and subject could withdraw their consent at any point. All subject recruitment and enrollment took place at Fujian Provincial Maternal and Children Hospital at the time of delivery. Using χ2 test for single factor analysis and logistic regression for multiple analyses Results There were 15 out of 22 single factors having statistical significances, including 2 maternal psychological, 4 physiological, 6 pathological and 3 prenatal health care factors respectively. When multi-factorial stepwise regression analyses was performed, there were 9 factors for main relative factors of LBW ,including women's height, number of prenatal examination, in-normal non-stress test, umbilical cord around the neck, retardation of the umbilical blood flow, week of gestation when the first examination was performed, premature rupture of membrane, preference on the sex of the infant, abnormal family history etc.were influencing the existence of LBW. Awareness on health information appeared to be a protective factor,suggesting that LBW could be prevented during the pregnant period. Conclusion Multiple factors seemed to be contributing to the incidence of low birth weight.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the prevalence of syphilis and risk factors on pregnant women in Fujian province.</p><p><b>METHODS</b>From July 1st, 2004 to June 30th, 2006, epidemiologic methods as questionnaires to fill in and rapid plasma reagent testing (RPR) were performed. Pregnant women with positive RPR test and then were confirmed by treponema pallidum test (TP). Intervention was provided to the pregnant women who were followed up to the postpartum periods. Results were compared during the peri-neonatal stage between syphilis-infected and non-infected women. Factors which were relative to syphilis infection were analyzed by simple and then further logistic regression analysis.</p><p><b>RESULTS</b>There were 38 418 pregnant women under study, of whom 772 were confirmed including 60 who were still pregnant. The prevalence of syphilis during pregnancy was 1.85% (712/38 418), with mostly underlying syphilis which played an important role during the neonatal stage. Main risk factors to have been found as: women's occupation, cultural background, place of living, husband's occupation, family income, having sexually transmitted disease(STD) infection. The prognosis of peri-neonatal stage was worse if the mother was having blood RPR test positive. Mortality of peri-neonatal, preterm birth rate and low-birth weight rate were found also higher among mothers when RPR was positive (P < 0.01).</p><p><b>CONCLUSION</b>The prevalence of syphilis in Fujian province was going up yearly. 8 factors including women's occupation, cultural background, place of living, received poor health education, having multiple sexual partners, husband's occupation, family income and having STD were main risk factors in the province, the mother's status of syphilis infection would strongly relate to the peri-neonatal stage of pregnancy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the prevalence and principal rules of women with syphilis during pregnancy and to develop relative methods to prevent maternal-fetal transmission.</p><p><b>METHODS</b>A nested case control study on epidemiologic research was used based on review and preview methods on prevention and cure. Targeting pregnant women with syphilis diagnosed during premarital or pregnancy stages and were identified through rapid plasma reagin test (RPR) but confirmed by treponema pallidum test (TP),a total number of 339 women receiving treatment, intervention and being followed throughout the pregnant and neonatal periods.</p><p><b>RESULTS</b>The prevalence of syphilis in pregnancy was 2.33%, and the positive rate in neonatal cord blood was closely associated with the opportunity of getting maternal treatment. The lowest RPR positive rate was among these women who got pregnant after receiving the treatment. The RPR positive rate of neonatal cord blood was positively relative to the mother's RPR titer. The higher was the mother's blood RPR titer, the worse the prenatal prognosis would turn to.</p><p><b>CONCLUSION</b>Mother's blood RPR titer and the opportunity of getting treatment were strongly associated with the positive rate in neonatal cord blood. Pregnancy after receiving the treatment was a powerful measure to prevent the maternal-fetal transmission of syphilis.</p>
