Objective To discuss the effect of triple therapy plus traditional Chinese medicine in the treatment of peptic ulcer (PU) caused by Helicobacter pylori ( Hp) .Methods 148 cases with PU were randomly divided into study group and control group of 74 cases in each group.The control group were treated with triple therapy (omeprazole +clarithromycin +amoxicillin), and the study group were given liver-discharging and heat-clearing and invigorating spleen and removing blood stasis decoction, additionally.Both groups received treatment for one course of 4 weeks.The changes of clinical symptoms, negative conversion ratio of Hp and adverse reaction were compared.Results The scores of clinical symptoms were all significantly decreased in both two groups after treatment (P<0.05), but the study group changed more than control group (P<0.05).The total effective rate was 95.95%, rather higher than 79.73% in control group (P<0.05).The negative conversion ratio of Hp was 82.43%, obviously higher than 64.86% in control group (P<0.05).The incidence of adverse reaction was 12.16% in study group, similar to 9.46% in control group.Conclusion Triple therapy plus traditional Chinese medicine can significantly improve the clinical symptoms, clinical effect and negative conversion ratio of Hp, and has a good safety and tolerability.

Lots of studies have identified the relationship between hyperuricemia and cardiovascular diseases. Many factors affect the metabolism of uric acid, such as diet, drug, internal environment of organism, etc. However, the relationship between hyperuricemia and cardiovascular diseases is not quite clear. In this review, we present recently published data about the association between hyperuricemia and selected cardiovascular diseases.

To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.

Aim To investigate the effect of acacetin on cell proliferation and the influence of acacetin on estrogen receptor expression in vitro.Methods The proliferation rates and the cell cycle changes of acace-tin-treated T47D cells were measured by sulforhodam-ine B(SRB)assay and flow cytometry,respectively. Moreover,the mRNA expressions of estrogen receptor-alpha(ERα),estrogen receptor-beta(ERβ)and pro-liferating antigen(Ki67)were determined by quantita-tive real time PCR (qPCR).Western blot was em-ployed to detect the ERαand ERβprotein expression. Results Acacetin significantly promoted the prolifera-tion and increased the amount of cells arrested in S and G2 /M phase under the concentration of 0.001 ~1 0μmol·L -1 .Ki67 mRNA level and the ERαprotein level in T47D cells were remarkably upregulated after acacetin treatment.To clarify which estrogen receptors played a role in acacetin induced the proliferation of T47D cells,the combination treatment of acacetin and ERαinhibitor (MPP)/ERβ inhibitor (PHTPP) was employed.We found that MPP could reverse the cell proliferation,the cell arrested in S and G2 /M phase and the increased Ki67 mRNA level induced by acace-tin.PHTPP also alleviated the T47D cell proliferation induced by acacetin,whereas no significant changes were found in cell cycle and Ki67 mRNA level.Con-clusion Acacetin stimulates the cell proliferation of T47D cells in the concentration from 0.001 μmol · L -1 to 1 0 μmol·L -1 ,which is mainly mediated by ERα.

Objective:To investigate the associations between serum uric acid levels during the third trimester of pregnancy and risks of adverse pregnancy outcomes.Methods:In this retrospective study, a cohort of 7 995 pregnant women who were hospitalized for childbirth from January 2014 to January 2019 were collected to compare pregnancy outcomes between subjects with or without hyperuricemia (HUA). A smooth curve analysis was used to evaluate the relationship between uric acid levels and preterm delivery, low birth weight and smaller than gestational age. Logistic regression analyses were performed to identify risk factors for adverse pregnancy outcomes, and the interaction of the factors.Results:During the third trimester of pregnancy, the uric acid levels of about 10% pregnant women were over 420 μmol/L. In those with HUA, the median neonatal birth weight was 2 590 (1 790, 3 410) g, the probability of premature birth was 49.81%, and the incidence of small than gestational age was 20.41%. These were significantly different from the women without HUA (the median neonatal birth weight: 3300 (2850, 3640) g; the probability of premature birth 23.09%; the incidence of small than gestational age 6.55%, respectively) (All P<0.001). Maternal uric acid levels were negatively correlated with neonatal birth weight, and positively correlated with the risk of smaller than gestational age. It has a U-shaped association with the probability of premature birth, and the lowest probability of premature birth was at 200-400 μmol/L of the uric acid. Risks of low birth weight (adjusted β=-5.22, 95% CI-6.46—-3.99) and smaller than gestational age (adjusted OR=1.03, 95% CI 1.02-1.04) were increased in the function of uric acid levels. High uric acid, hypertension, oligoamnios and preeclampsia were important risk factors for the adverse pregnancy outcomes. The risk of preterm delivery and low birth weight enhanced when hyperuricemia combined with hypertension and preeclampsia. Conclusions:Serum uric acid level can be used as one of reliable markers for predicting adverse pregnancy outcomes, which might provide theoretical basis for clinical intervention in practice.

Objective To investigate the clinical effect of endovascular embolization in treating spinal dural arteriovenous fistulae, and to discuss its imaging manifestations. Methods A total of 7 patients with spinal dural arteriovenous fistulae were included in this study. Endovascular embolization was carried out in all the 7 patients. The clinical data, including epidemiology, spinal MRI and DSA manifestations, therapeutic method and follow-up findings, were retrospectively analyzed. Results Abnormal MRI manifestations of spinal cord were demonstrated in all 7 patients. After the diagnosis was confirmed by DSA, endovascular embolization was carried out. All patients were followed up for 6 months, and their clinical symptoms were improved in different degrees. N-butyl cyanoacrylate (NBCA) glue was used as embolization agent in 4 cases, and no recurrence was observed in them. Onyx liquid glue was used in 3 patients, and in one of them the arteriovenous fistula recurred. Conclusion For the treatment of spinal dural arteriovenous fistulae, endovascular embolization is effective and safe although further investigation is still needed.

[ABSTRACT]AIM:Toobservetheeffectofazithromycinontheratswithchronicobstructivepulmonarydisease ( COPD) , and to explore the underlying mechanism about the airway inflammation and mucus hypersecretion.METH-ODS:Male SD rats were randomly divided into normal control group, COPD model group, azithromycin treatment group. The COPD model was established by the method of cigarette smoking combined with intratracheal injection of LPS.Patho-logical changes of the bronchi and lung tissues of the rats were observed with HE staining.Pulmonary ventilation function in the rats was detected with pulmonary function instrument.The levels of IL-8, IL-17 and TNF-αin bronchoalveolar lavage fluid (BALF) were measured by ELISA.The expression of MUC5ac and TLR4 at mRNA and protein levels in bronchi and lung tissues was determined by real-time PCR and Western blot.RESULTS:HE staining showed that the changes of bron-chi and lung tissues in model group were consistent with typical pathological manifestations of COPD .Compared with model group, these changes were alleviated in treatment group.The pulmonary functions in model group were significantly de-creased compared with control group.The levels of IL-8, IL-17 and TNF-αin the BALF in model group were significantly increased compared with control group (P<0.05).The expression of MUC5ac and TLR4 at mRNA and protein levels in model group was significantly higher than that in control group (P<0.05).Compared with model group, the degree of the descent in pulmonary function in treatment group was significantly lessened.Compared with model group, the levels of IL-8, IL-17 and TNF-αin treatment group were significantly inhibited (P<0.05).Furthermore, the expression of MUC5ac and TLR4 at mRNA and protein levels in treatment group was significantly lower than that in model group ( P<0.05 ) . CONCLUSION:Azithromycin decreases the levels of IL-8, IL-17 and TNF-αin the BALF of COPD model rats, inhibits the protein expression of MUC5ac and TLR4 in the lung tissues, thus playing a preventive and therapeutic role to reduce airway inflammation and airway mucus hypersecretion.
