Objective To investigate the appropriate timing of B-lynch suture in the treatment of atonic postpartum hemorrhage during cesarean section.Methods A total of 90 patients with atonic postpartum hemorrhage during cesarean section from January 2012 to December 2014 in our hospital were included in the study.They were divided into two groups, early suture group (applying B-lynch suture when the amount of postpartum hemorrhage reaching 500 ml, n=66 cases) and late suture group (applying B-lynch suture when the amount of postpartum hemorrhage reaching 1000 ml, n=24 cases).The hemostatic effect, amount of bleeding, blood transfusion rate, incidence of DIC, duration of hospitalization, and the puerperal morbidity were compared between the two groups.Results All the 90 patients were successfully treated and were discharged after comprehensive treatment.The amount of postpartum hemorrhage of the early suture group was (656±118) ml, which was significantly less than that of the late suture group [(1550±432) ml, t=-10.003, P=0.001].The rate of blood transfusion of the early suture group was 3.0% (2/66), which was significantly lower than that of the late suture group [(50.0%, 12/24), x2=26.092, P=0.000].There was no case of DIC in the early suture group, and the incidence of DIC in the late suture group was 16.7% (4/24), with the difference statistically significant (Fisher''s exact test, P=0.004).The puerperal morbidity in the early suture group was 3.0% (2/66) and that of the late suture group was 25.0% (6/24), with statistically significant difference (x2=7.952, P=0.005).There was no statistically significant difference in the hospitalization stay between the two groups (P>0.05).Conclusions B-Lynch suture is an effective method in the treatment of atonic postpartum hemorrhage during cesarean section, and early use of it can get better curative effect, such as less bleeding amount and lower rates of blood transfusion, DIC and complications like puerperal morbidity.In case the bleeding volume reaches 500 ml and the general conservative hemostatic methods are ineffective, B-Lynch suture is recommended immediately.

Hepatitis B virus(HBV) infection is a severe health problem in the world.However,there is still not a satisfactory therapeutic strategy for the HBV infection.To search for new anti-HBV agents with higher efficacy and less side-effects,the inhibitory activities of traditional Chinese medicine Rheum palmatum L.ethanol extract(RPE) against HBV replication were investigated in this study.Quantitative real-time polymerase chain reaction(PCR) was employed to analyze the inhibitory activity of RPE against HBV-DNA replication in a stable HBV-producing cell line HepAD38; the expression levels of HBV surface antigen(HBsAg) and e antigen(HBeAg) were also determined by enzyme linked immunosorbent assay(ELISA) after RPE treatment.RPE could dose-dependently inhibit the production of HBV-DNA and HBsAg.The concentration of 50% inhibition(IC50) was calculated at 209.63,252.53 μg/mL,respectively.However,its inhibitory activity against HBeAg expression was slight even at high concentrations.RPE had a weak cytotoxic effect on HepAD38 cells(CC50 = 1 640 μg/mL) and the selectivity index(SI) was calculated at 7.82.Compared with two anthraquinone derivatives emodin and rhein,RPE showed higher ability of anti-HBV and weaker cytotoxicity.So Rheum palmatum L.might possess other functional agents which could effectively inhibit HBV-DNA replication and HBsAg expression.Further purification of the active agents,identification and modification of their structures to improve the efficacy and decrease the cytotoxicity are required.

BACKGROUND:Excessive apoptosis and decreased infiltration of cytotrophoblasts are essential causes for hypertension in pregnancy. Human placenta-derived mesenchymal stem cels contribute to damage repair, which has been shown in many studies, and moreover, human placenta-derived mesenchymal stem cels have a certain endocrine function and can act on the other tissues in an autocrine or paracrine manner. Therefore, we attempt to explore whether the human placenta-derived mesenchymal stem cel can repair damaged cytotrophoblasts, and then to gestational hypertension.
METHODS/DESIGN:This is a randomized controled cytological experiment. Human placenta-derived mesenchymal stem cel culture medium is colected and filtrated as human placenta-derived mesenchymal stem cel conditioned medium. Human cytotrophoblasts, JEG-3 cels, are cultured and randomized into three groups:15% normal pregnant serum is added in control group; 15% serum from severe pre-eclampsia patients is added in gestational hypertension model group; and in condition medium group, 15% serum from severe pre-eclampsia patients is added for 24 hours of culture, and then human placenta-derived mesenchymal stem cel conditioned medium containing 15% serum from severe pre-eclampsia patients is used instead. Flow cytometry is used to detect cel apoptosis rate.
DISCUSSION: This study wil help to find the feasibility of cel transplantation for gestational hypertension by exploring the effect of human placenta-derived mesenchymal stem cels on cytotrophoblasts function in gestational hypertension.
ETHICAL APPROVAL: The protocol is approved by the Ethics Committee of Shenyang Central Hospital of Shenyang Medical University. Informed consent is obtained from normal and pre-eclampsia women in pregnancy.

Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.

OBJECTIVETo explore the intervention of Fagopyrum cymosum (Trev.) Meisn alcohol extract (FAE) on defecation function and motor functions of isolated colons of diarrhea-predominant irritable bowel syndrome (D-IBS) rats and to study its underlying mechanism.

METHODSThe D-IBS rat model was established by neonatal pups maternal separation (NMS) combined with intracolonic infusion of acetic acid (AA). Adult IBS rats were randomly divided into the pre-intervention control group (n = 10, with no gastrogavage), the normal saline control group (n = 10, administered with normal saline by gastrogavage), the pre-treatment model group (n = 8,with no gastrogavage),the normal saline model group (n = 8, administered with normal saline by gastrogavage), the low dose FAE group (n = 8, administered with 6 g/kg FAE by gastrogavage), the high dose FAE group (n = 8, administered with 24 g/kg FAE by gastrogavage), and the Pinaverium Bromide group (n = 8, administered with 0.02 g/kg Pinaverium Bromide by gastrogavage). All medication was performed once daily for 2 weeks. The abdominal withdrawal reflex (AWR) was employed to evaluate the visceral hypersensitivity; their loose and watery stool grade was assessed by Bristol scores for stool consistency; and their fresh feces weight was calculated. In vitro effect of different concentrations of FAE and Pinaverium Bromide (0.02 μg/mL) on spontaneous contraction and spasmodic contraction induced by acetylcholine (Ach) in rats' isolated colon were observed and the influence on the intestinal calcium channel was evaluated.

RESULTSCompared with the pre-intervention control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the pre-intervention model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased drastically (P < 0.01). Compared with the normal saline control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the normal saline model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased markedly (P < 0.01). Compared with the normal saline model group, the pain pressure threshold of 24 g/kg FAE and Pinaverium Bromide group significantly increased (P < 0.05). The loose and watery stool grade and fresh feces weight decreased obviously in the low dose FAE group, the high dose FAE group, and the Pinaverium Bromide group (P < 0.05). FAE (30, 100, 300, 1,000, and 3,000 μg/mL) and Pinaverium Bromide could significantly inhibit spontaneous contraction of isolated intestines (P < 0.05, P < 0.01), and FAE (30, 100, and 300 x 10(-6) g/mL) could remarkably inhibit their spasmodic contraction and contractile tension induced by Ach and Ca2+ respectively (P < 0.05, P < 0.01) in a concentration-dependent manner. Pinaverium Bromide also could significantly inhibit Ach and Ca2+ induced contraction.

CONCLUSIONEffective components of FAE improved the defecation function and inhibited enterospasm induced intestinal hyperactivity in IBS model rats via antagonizing calcium channel competitively and inhibiting colonic motility dose-dependently.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.
