ObjectiveTo observe the clinical effectiveness and safety of Dingchan Granule （定颤颗粒） for paroxysmal atrial fibrillation with syndrome of qi stagnation and blood stasis. MethodsUsing a randomised， double-blind， placebo controlled study method， 90 patients with paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome were divided into 45 cases each in the treatment group and the control group. Both groups were given conventional western medicine treatment， and the treatment group was additionally treated with Dingchan Granule， while the control group was treated with Dingchan Granule placebo， both of which were taken orally for 8 g each time twice a day. Both groups were treated for 8 weeks. We compared the clinical effectiveness， the improvement of traditional Chinese medicine （TCM） symptoms and the recovery rate of atrial fibrillation between the two groups. We compared the number and duration of atrial fibrillation episodes， TCM symptoms score， atrial fibrillation symptom classification， 24-hour average ventricular rate， Pittsburgh Sleep Quality Index （PSQI）， anxiety index， depression index before and after treatment， and evaluated the safety of the two groups. ResultsThe total clinical effectiveness rate in the treatment group was 82.22% （37/45）， which was better than 60.00% （27/45） in the control group （P＜0.05）. The total effective rate of TCM syndrome effectiveness in the treatment group was 88.89% （40/45）， which was better than 66.67% （30/45） in the control group （P＜0.05）； and the rate of atrial fibrillation regression in the treatment group was 26.67% （12/45）， better than 6.67% （3/45） in the control group （P＜0.05）. The number and duration of atrial fibrillation episodes in both groups were significantly decreased （P＜0.01）， and the number and duration of atrial fibrillation episodes in the treatment group were lower than those in the control group （P＜0.01）. The TCM syndrome scores of both groups after treatment were significantly lower than before treatment （P＜0.01）， and the scores of the treatment group was lower than those of the control group （P＜0.05）. The severity of atrial fibrillation symptoms and the grading of atrial fibrillation symptoms in both groups after treatment were improved （P＜0.01）， and the degree of symptom improvement in the treatment group was better than that in the control group （P＜0.01）. The 24-hour average ventricular rate of both groups after treatment was significantly lower （P＜0.01）. The PSQI， anxiety index and depression index of the treatment group were all lower than before treatment （P＜0.01）， while the PSQI and anxiety index of the control group were both lower than before treatment （P＜0.01 or P＜0.05）， the PSQI， anxiety index and depression index of the treatment group being lower than those of the control group （P＜0.05 or P＜0.01）. No adverse events occurred in both groups， and no abnormalities were observed in blood， urine， stool routine， liver and kidney function， and coagulation function indexes. ConclusionDingchan Granule for paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome can alleviate clinical symptom， improve TCM symptom scores， increase atrial fibrillation recovery rate， stabilise the average ventricular rate， and significantly improve the quality of sleep， alleviate the anxiety and depression， with a good safety profile.

OBJECTIVES: To explore the association between GPSM2 expression level and gastric cancer progression and analyze the functional pathways and action mechanism of GPSM2. METHODS: We analyzed GPSM2 expression levels in gastric cancer tumors based on data from the GEPIA database and the clinical data of 109 patients. Public databases enrichment analysis were used to assess the impact of GPSM2 expression level on survival outcomes and the functional pathways and action mechanism of GPSM2. We further observed the effects of GPSM2 knockdown and overexpression on proliferation, migration and apoptosis of MGC803 cells using CCK-8 assay, colony formation assay, flow cytometry and immunoblotting and on the growth of MGC803 cell xenografts in nude mice. RESULTS: Bioinformatic analysis and immunohistochemical staining of the clinical specimens both revealed high GPSM2 expressions in gastric cancer (P<0.01). A high GPSM2 expression was significantly correlated with T3-4 stages, N2-3 stages, a carcinoembryonic antigen (CEA) level ≥5 μg/L, and a carbohydrate antigen (CA) 19-9 level ≥37 kU/L (P<0.05). Cox regression analysis identified high GPSM2 expression as an independent risk factor affecting 5-year survival of the patients (P<0.05). Gene ontology (GO) analysis suggested that GPSM2 was involved in cell cycle regulation. In MGC803 cells, GPSM2 overexpression significantly promoted cell proliferation and G1/S transition and xenograft growth in nude mice. KEGG pathway enrichment analysis indicated that GPSM2 executed its biological functions by regulating the p53 signaling pathway, which was confirmed by the results of immunoblotting experiments showing suppression of p53 signaling pathway activity in GPSM2-over expressing MGC803 cells. CONCLUSIONS GPSM2 is highly expressed in gastric cancer to affect patient prognosis by promoting tumor cell proliferation and G1/S transition possibly via inhibiting the p53 pathway.

Objective:To explore the effects of pelvic-abdominal mechanics exercises during pregnancy on improving pelvic floor function in primiparous women during the perinatal period.Methods:A single-center prospective study selected 200 primipara of singleton pregnancies with prenatal care and delivery established at Shanghai Tongren hospital from June 2022 to June 2023 as the study subjects. Participants were divided into two groups: the exercise group (100 cases) and the control group (100 cases) by using a random number table method, five participants dropped out of the study due to reasons such as follow-up failure. Ultimately, the exercise group consisted of 97 cases, while the control group consisted of 98 cases. Participants who engaged in pelvic-abdominal mechanics exercises for at least 3 months, exercising once a week, were included in the exercise group. Those who did not engage in exercise were included in control group. Comparing the two groups in terms of pregnancy discomfort symptoms, delivery outcomes, postpartum pelvic floor electromyography results, postpartum quality of life, and pelvic floor disease incidence. The statistical methods utilized included independent t-test, Pearson chi-square test, Fisher′s exact test, and Mann-Whitney U test. Results:In the late stage of pregnancy, the VAS score for low back pain was 5.05±1.22 in the exercise group and 5.47±1.55 in the control group, with a statistically significant difference ( t=2.090, P<0.05). The PFDI-20 score was 23.33±8.41 in the exercise group and 25.76±8.34 in the control group, with a statistically significant difference ( t=2.026, P<0.05). The PFIQ-7 score was 19.21±7.69 in the exercise group and 26.66±6.19 in the control group, with a statistically significant difference ( t=6.851, P<0.05). There was no statistically significant difference in sleep quality and incidence of urinary incontinence between the two groups in late pregnancy ( t=1.252, P=0.396, P>0.05). In terms of childbirth outcomes, the exercise group had a vaginal delivery rate of 81.44% (79 cases), while the control group had a rate of 64.28% (63 cases), with a statistically significant difference (χ 2=9.022, P<0.05). The duration of the second stage of labor was (42.68±21.38) minutes in the exercise group and (50.54±21.33) minutes in the control group, with a statistically significant difference ( t=2.178, P<0.05). At 42 days postpartum, the evaluation of pelvic floor function showed that the vaginal pressure in the exercise group was 62.19±10.04, while in the control group it was 52.68±15.55, with a statistically significant difference ( t=-5.074, P<0.05). The MOS grading in the exercise group was 3.82±1.26, whereas in the control group it was 2.34±1.55, with a statistically significant difference ( t=-7.355, P<0.05). In terms of the incidence of postpartum pelvic floor disorders, the occurrence of pelvic organ prolapse was 7.22% in the exercise group and 12.24% in the control group, with no statistically significant difference (χ 2=1.402, P>0.05). The occurrence rate of stress urinary incontinence was 13.4% in the exercise group and 30.61% in the control group, with a statistically significant difference ( P=0.015, P<0.05). Conclusion:Pelvic-abdominal mechanics exercises may have some advantages in reducing symptoms related to perinatal pelvic floor dysfunction, enhancing pelvic floor function, and preventing the occurrence of pelvic floor disease.

Objective To explore the regulatory role of Abelson interactor 2(ABI2)in progression and prognosis of gastric cancer.Methods TIMER2.0,GEPIA,Kaplan-Meier Plotter and DAVID databases were used to analyze ABI2 expression in pan-cancer and its association with the prognosis of gastric cancer.Gastric cancer and adjacent tissues from 120 patients undergoing radical gastrectomy in our hospital between January,2016 and October,2018 were examined for ABI2 expression and its correlation with disease progression and prognosis.MGC-803 cell models of ABI2 knockdown and overexpression were established for observing the changes in cell proliferation,migration,and invasion,and the impact of ABI2 expression modulation on xenograft growth was evaluated in nude mice.Results Database analysis and examination of the clinical samples showed that ABI2 was highly expressed in gastric cancer tissues.Survival analysis suggested that gastric cancer patients with a high expression of ABI2 had a reduced postoperative 5-year survival rate(P<0.0001),and further Cox univariate and multivariate survival analyses indicated that a high ABI2 expression was an independent risk factor affecting the patients survival outcomes(P=0.022,HR=1.887,95%CI:1.096-3.249).Enrichment analysis suggested the involvement of ABI2 in Wnt signaling.In MGC-803 cells,ABI2 overexpression promoted cell proliferation and xenograft growth in nude mice,increased the expressions of vimentin and N-cadherin,and lowered E-cadherin expression,while ABI2 knockdown produced the opposite effects.Mechanistic analysis revealed that ABI2 overexpression promoted the expressions of Wnt2 and β-catenin in both MGC-803 cells and the xenografts,and their expressions were significantly lowered by ABI2 knockdown.Conclusion ABI2 is highly expressed in gastric cancer,which affects long-term prognosis of the patients,possible due to its regulatory effect on Wnt signaling to promote proliferation,migration and invasion of gastric cancer cells.

Objective To investigate the correlation of CEP192 expression with prognosis of gastric cancer and biological behaviors of gastric cancer cells.Methods Public databases and clinical tissue samples were used to examine CEP192 expression level in gastric cancer.Kaplan-Meier survival curves,univariate and multivariate Cox regression analyses,ROC curves and bioinformatics analyses were used to explore the risk factors affecting the 5-year postoperative survival,the correlation of CEP192 expression level with the patients'survival,and its biological role in gastric cancer development.In gastric cancer MGC-803 cells with lentivirus-mediated CEP192 interference or overexpression,cell proliferation and expressions of PLK1,CDK1 and Cyclin B1 were examined with CCK-8 assay and Western blotting.The effects of CEP192 knockdown or overexpression on tumorigenesis of MGC-803 cells was observed in nude mice,and the expressions of PLK1,CDK1 and Cyclin B1 in the xenografts were detected.Results CEP192 was highly expressed in gastric cancer and associated with poor prognosis of the patients(P<0.05).High expression of CEP192,CEA≥5 ng/mL,CA199≥37 IU/mL,T3-4 stage,and N2-3 stage were independent risk factors affecting the patients'5-year postoperative survival(P<0.05).Bioinformatics analyses suggested that CEP192 was involved in several vital biological processes and positively regulated cell cycle progression.In MGC-803 cells,CEP192 knockdown significantly inhibited cell proliferation and lowered the expression levels of PLK1,CDK1,and Cyclin B1,while its overexpression produced the opposite effects.In the nude mouse models,CEP192 knockdown resulted in lowered tumorigenic potential of MGC-803 cells and decreased protein levels of PLK1,CDK1,and Cyclin B1 in the xenografts,while CEP192 overexpression in MGC-803 cells caused the opposite changes.Conclusion CEP192 overexpression is correlated with unfavorable outcomes of gastric cancer patients and promotes gastric cell proliferation by regulating the key proteins during G2/M phase transition.

Objective:To determine the median effective dose (ED 50) of remimazolam for preoperative sedation in pediatric patients of different ages. Methods:This was a prospective study. American Society of Anesthesiologists Physical Status classification I or Ⅱ pediatric patients, aged 1-6 yr, scheduled for elective surgery in our hospital from July to December 2023, in whom the preoperative anxiety was still not relieved after non-drug intervention (preoperative separation anxiety score [PSAS]≥3), were selected. According to the age, the children were divided into 1-<2 yr group, 2-<3 yr group, 3-<4 yr group, 4-<5 yr group and 5-6 yr group. A child's PSAS score = 1 at the time of separation from parents was classified as satisfactory sedation, and a PSAS score ≥ 2 was classified as unsatisfactory sedation. The initial dose of remimazolam in each group was 0.3 mg/kg, dose ratio 1.15. If the child was satisfactorily sedated, the next patient received a lower dose of remimazolam, or conversely if the child was not satisfactorily sedated, a higher dose was given in the next patient. The test was ended when 7 alternating waveforms appeared. The Dixon-Massey method was used to calculate the ED 50 and 95% confidence interval. Results:In 1-<2 yr group, 2-<3 yr group, 3-<4 yr group, 4-<5 yr group and 5-6 yr group, a total of 120 children were included in this study, with 26, 23, 21, 27 and 23 cases, respectively, and the ED 50 (95% confidence interval) of remimazolam for preoperative sedation was 0.152 (0.126-0.178), 0.159 (0.135-0.183), 0.171 (0.147-0.196), 0.150 (0.126-0.174), and 0.146 (0.121-0.170) mg/kg, respectively. There was no significant difference between the groups ( P>0.05). Conclusions:The ED 50 of remimazolam for preoperative sedation is 0.152, 0.159, 0.171, 0.150 and 0.146 mg/kg for every 1 yr in children aged 1-6 yr, and the age factor does not affect the preoperative sedative effect of remimazolam in children of this age group.
