Objective To investigate the clinical efficacy of trimebutine combined with Xiangsha Pingwei in the treatment of functional dyspepsia and its effect on gastrointestinal hormone.Methods One hundred and twenty cases of functional dyspepsia were randomly divided into the control group and observation group,60 cases in each group.The control group was treated with trimebutine 0.2 g,3 times/d and the observation group was treated with trimebutine 0.2 g,3 times/d and Xiangsha Pingwei 10 g,2 times/d.Both groups were treated for four weeks,a course of treatment.Clinical efficacy and the influence on gastrointestinal hormone levels were compared between the two groups.Results The symptoms scores in both groups all decreased significantly after treatment.While the postprandial fullness scores,early satiety scores and epigastric pain scores in the observation group were significantly lower than those in the control group (0.62±0.12 vs.1.85±0.25,0.56±0.14 vs.1.46±0.21,0.48±0.15 vs.1.32±0.12,t=34.36,27.62,33.87,P<0.05).The total effective rate in the observation group was significantly higher than that in the control group (90.00% vs.73.33%,χ2=5.57,P<0.05).MOT and GAS levels in both groups increased significantly.While MOT and GAS levels in the observation group were significantly higher than those in the control group (MOT: (355.2±78.1) ng/L vs.(288.7±82.4) ng/L;GAS:(96.5±17.6) ng/L vs.(88.4±16.0) ng/L,t=4.54,2.64,P<0.05).The somatostatin (SS) level in both groups decreased significantly.While the SS level in the observation group was significantly lower than that in the control group ((41.1±11.1) ng/L vs.(48.9±12.9) ng/L,t=3.55,P<0.05).Conclusion Trimebutine combined with Xiangsha Pingwei can significantly improve the clinical symptoms and gastrointestinal hormone in patients with functional dyspepsia.

Objective: To evaluate the effect of parametrial status on FIGO stage IIIC1 cervical cancer. Methods: A retrospective study was conducted from June 1, 2009, to December 31, 2018.Patients with stage IIIC1 cervical cancer were included and stratified into two groups based on the status of parametrial involvement. Patients with IIIA or IIIB were selected as control. The primary outcomes are overall survival (OS) and progression-free survival (PFS). Results: Of 586 patients included, 377 patients were stage IIIC1 (group A) and 209 patients were stage IIIA/IIIB (group B). Compared control, stage IIIC1 was not associated with worse 5-year OS or PFS. Of the stage IIIC1 patients, 58.1% without parametrial involvement (group A1) and 41.9% with parametrial involvement (group A2). Patients of group A1 showed a better prognosis than group A2 both in 5-year rates of OS (79.09% vs. 59.43%, p<0.001) and PFS (73.27% vs. 56.95%, p=0.0002). However, patients of group A1 showed a better prognosis than group B both in OS and PFS. Also, patients of group A2 showed a comparable prognosis to group B both in OS and PFS. Conclusion Reclassification of stage IIIC1 cervical cancer without parametrial into a new stage is more appropriate and improves discriminatory ability.

BACKGROUND: Pathological cardiac hypertrophy is one of the main activators of heart failure. Currently, no drug can completely reverse or inhibit the development of pathological cardiac hypertrophy. To this end, we proposed a silicate ion therapy based on extract derived from calcium silicate (CS) bioceramics for the treatment of angiotensin II (Ang II) induced cardiac hypertrophy. METHODS: In this study, the Ang II induced cardiac hypertrophy mouse model was established, and the silicate ion extract was injected to mice intravenously. The cardiac function was evaluated by using a high-resolution Vevo 3100 small animal ultrasound imaging system. Wheat germ Agglutinin, Fluo4-AM staining and immunofluorescent staining was conducted to assess the cardiac hypertrophy, intracellular calcium and angiogenesis of heart tissue, respectively. RESULTS: The in vitro results showed that silicate ions could inhibit the cell size of cardiomyocytes, reduce cardiac hypertrophic gene expression, including atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and b-myosin heavy chain (b-MHC), decrease the content of intracellular calcium induced by Ang II. In vivo experiments in mice confirmed that intravenous injection of silicate ions could remarkably inhibit the cardiac hypertrophy and promote the formation of capillaries, further alleviating Ang II-induced cardiac function disorder. CONCLUSION This study demonstrated that the released silicate ions from CS possessed potential value as a novel therapeutic strategy of pathological cardiac hypertrophy, which provided a new insight for clinical trials.
