Objective To observe the effect of acupuncture on proximal gastric accommodation and gastric emptying of functional dyspepsia (FD) patients.Method Eighty FD patients were randomized into a treatment group and a control group by using random number table method according to registration order, 40 cases in each group. The treatment group was intervened by acupuncture treatment, while the control group didn't receive any treatment. The changes of symptom scores, maximum satiety threshold and 2-hour gastric emptying rate in the two groups were observed after 1-month treatment.Result The symptom scores, maximum satiety threshold and 2-hour gastric emptying rate were significantly changed in the treatment group after the intervention (P<0.01). The symptom scores, maximum satiety threshold and 2-hour gastric emptying rate didn't show significant changes in the control group after the treatment (P>0.05). There were significant differences in comparing the symptom scores, maximum satiety threshold and 2-hour gastric emptying rate between the two groups after the treatment (P<0.01). The changes of symptom scores, maximum satiety threshold and 2-hour gastric emptying rate in the treatment group were significantly different from those in the control group (P<0.01).Conclusion Acupuncture can significantly improve the proximal gastric accommodation and gastric emptying of FD patients.

The rat model of dysmenorrhea, pelvic inflammation disease (PID), and uterine myoma were established to observe the effect ofGui-Zhi Fu-Ling Capsule (GZFLC) with the changes of main components. The molecular imprinted technology was used to quantitatively knock out main components in GZFLC (the knocked-out ratios were 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%). And the observation was made on the writhing times, latency, and effects on ET-1 and PGF2α of uterine tissues in the pitocin-induced dysmenorrhea rat model. Effects on TNF-α and IL-2 were observed in PID rat model induced by mixed bacteria plus mechanical damages. Effects on the weight and index of uterus, levels of E2 and P in serum were detected on the uterine myoma rat model induced by estrogen-burden. The results showed that the GZFLC efficacy was decreased with gradient knockout of 15 main components. When 10%-40% was knocked out, there was still significant difference compared to the model group (P < 0.01). However, when 50%-90% was knocked out, there was no significant difference compared to the model group (P > 0.05). Meanwhile, the GZFLC efficacy was decreased significantly compared to the GZFLC group (P <0.05, orP < 0.01). It was concluded that 15 chemical compounds, which included gallic acid, paeoniflorin, paeonol, and etc., may be the main material basis of GZFLC. Meanwhile, it provided a useful reference for the quality control of main components in GZFLC.

Objective:To summarize and compare the characteristics of oral microbiota in women during the preconception period and the third trimester.Methods:This retrospective cohort study involved 55 women who were recruited in the Preconceptional Offspring Trajectory Study (PLOTS) conducted by Fudan University and followed up to the third trimester in the Maternal and Child Health Care Hospital of Jiading District of Shanghai from September 2016 to December 2019. A total of 110 unstimulated saliva samples were collected in the preconception period ( n=55) and the third trimester ( n=55). Features of oral microbiota in the samples were analyzed by 16S rRNA gene-based sequencing. Moreover, the related factors were also analyzed. Paired t test or Wilcoxon matched-pairs signed-ranks test were used to analyze the differences in α-diversity during preconception and the third trimester; t test, analysis of variance (ANOVA), Kruskal-Wallis test and Mann-Whitney U test for comparison between groups with different characteristics and permutational multivariate analysis of variance (PerMANOVA) for β-diversity were used; Linear discriminant analysis (LDA) effect size (LEfSe 1.0) was used to identify the iconic oral flora. Results:(1) The Ace index of oral microbiota was significantly lower in the third trimester than that in the preconception period [661.14(578.15-752.85) vs 730.64 (632.40-911.00), T=1 077.00, P=0.010]. There was also a significance difference in β-diversity ( F=12.539, R2=0.104, P=0.001). Some species such as Saccharibacteria_TM7_G3, Prevotella_7, Absconditabacteria_SR1_G1, Porphyromonas, Ruminococcaceae_UCG_014, Prevotella, Peptostreptococcus, Prevotella_2, Alloprevotella, Parvimonas, Solobacterium and Eubacterium_nodatum_group in saliva were statistically more abundant in the third trimester than those in the preconception period (all P<0.05). (2) The third-trimester Shannon index was lower among those with lower income [5.44 (5.08-5.77) vs 5.75 (5.44-6.12), U=219.00, P=0.029] and those with gargle habit after meal or dessert [5.36 (4.91-5.48) vs 5.72 (5.44-6.05), U=374.00, P=0.046]. Conclusions:The features of oral microbiota vary in women during the preconception period and the third trimester. There is a significant increase in the abundance of oral pathogenic and opportunistic bacteria in the third trimester.

To investigate the relationship between serum retinol-binding protein 4(RBP4) and gestational diabetes mellitus (GDM) in Chinese Han pregnant women.195 (23-42 years) pregnant women were recruited (July 2005 to December 2007) from the Department of Gynecology and Obstetric in Ruijin Hospital during their visiting for routine prenatal examination.99 subjects belonged to GDM group,and 96 belonged to the group with normal glucose tolerance (NGT).65 non-pregnant healthy women served as control.Serum RBP4 was measured using sandwich enzyme linked immunosorbent assay (ELISA).Pregnant women had higher level of serum RBP4 than that of non-pregnant control.The concentration of serum RBP4 was significantly increased in GDM group as compared with NGT group[(43.04±1.85 vs 33.84±2.17) rag/L,P<0.01].Multiple stepwise regression analysis showed that triglycerides and homeostasis assessment for insulin resistance (HOMA-IR) were independent variables of RBP4 (r2 =0.165) in pregnant women.The results suggest that serum RBP4 level is significantly increased in pregnant women.Women with GDM had even higher RBP4 level than that of normal pregnant women,and RBP4 levele was positively correlated with triglycerides and HOMA-IR.

OBJECTIVETo evaluate interfering effect of several short interfering RNAs (siRNA) on HCV 5' untranslated region(5' UTR).

METHODSThe green fluorescent protein (GFP) was used as reporter gene. A fused gene of HCV-5'UTR and GFP was constructed. It was cloned into the plasmid pCDNA3.1 named as pcDNA-HCV-5'UTR-GFP. Three siRNAs were designed and transfected into HepG2 cells with pcDNA-HCV-5'UTR-GFP. The change of the fluorescence intensity of HepG2 cells was shown by fluorescence microscopy and numerically detected under 488 nm wave length by flow cytometry.

RESULTSThe fused gene of HCV-5'UTR and GFP was successfully constructed. The seven groups displayed inhibitory effects on the gene expression of GFP. The inhibition rates of siRNA A, B and C were 68.4 percent, 72.6 percent and 75.6 percent, respectively. The inhibitory rates of siRN A + B, siRN B +C and siRN A +C were 91.8 percent, 87.2 percent and 92.4 percent, respectively. The inhibitory rates of siRN A+B +C was the highest, up to 95.7 percent.

CONCLUSIONThese siRNAs could inhibit expression of HCV 5'UTR gene, the inhibitory effect of combined siRNA was better than that of single siRNAs.

BACKGROUND: Little is known about the risk factors for sudden cardiac death (SCD) in the overall hospitalized cardiac department population. This study was conducted to investigate the risk factors and develop a predictive model for SCD in a hospitalized cardiac department population. METHODS: We conducted a retrospective study of patients admitted to the cardiac department of the First Affiliated Hospital of Xinjiang Medical University from June 2015 to February 2017. We collected the clinical data from medical records. Multiple stepwise logistic regression analysis was carried out to confirm the risk factors for SCD and develop a predictive risk model. The risk score was assessed by the area under receiver operating characteristic (AUROC) curve and the Hosmer-Lemeshow goodness-of-fit test. RESULTS: A total of 262 patients with SCD and 4485 controls were enrolled in our study. Logistic regression modeling identified eight significant risk factors for in-hospital SCD: age, main admitting diagnosis, diabetes, corrected QT interval, QRS duration, ventricular premature beat burden, left ventricular ejection fraction, and estimated glomerular filtration rate. A predictive risk score including these variables showed an AUROC curve of 0.774 (95% confidence interval: 0.744-0.805). The Hosmer-Lemeshow goodness-of-fit test showed the chi-square value was 2.527 (P = 0.640). The incidence of in-hospital SCD was 1.3%, 4.1%, and 18.6% for scores of 0 to 2, 3 to 5 and ≥6, respectively (P < 0.001). CONCLUSIONS Age, main admitting diagnosis, diabetes, QTc interval, QRS duration, ventricular premature beat burden, left ventricular ejection fraction, and estimated glomerular filtration rate are factors related to in-hospital SCD in a hospitalized cardiac department population. We developed a predictive risk score including these factors that could identify patients who are predisposed to in-hospital SCD.
