Objective To explore mechnism and effect of fentanyl on proliferation of gastric cancer SGC-7901 cell.Methods Gastric cancer SGC-7901 cell was cultured with fentanyl of 0 (negative control), 0.5, 5 and 50 nmol/L, MTT method was used to detect the effect of fentanyl on SGC-7901 viability.The effect of fentanyl on SGC-7901 cell cycle was measured by flow cytometry.The level of cell related protein,cell cycle protein cyclin D1, Bcl-2.Results Compared with control group, fentanyl (0.5, 5, 50 nmol/L) could inhibit SGC-7901 cell viability, and the inhibitory rate was highest at 48 h.0.5, 5, 50 nmol/L fentanyl made cell cycle arrested in G1 phase.Compared with control group, fentanyl can significantly inhibit cyclinD1 and Bcl-2 expression with drug concentration increasing(P<0.05).Conclusion These results suggeste fentanyl inhibit proliferation of gastric cancer SGC-7901 cell.

In recent years, exercise testing has been increasingly used in pediatrics, especially in pediatric cardiovascular diseases.Its ability to monitor heart rate, blood pressure, electrocardiogram, oxygen saturation, and expiratory gas analysis is of great clinical value.In pediatric cardiovascular diseases, exercise testing can further evaluate arrhythmias, facilitate the differential diagnosis of syncope, and detect early myocardial perfusion defects in children with cardiomyopathy and Kawasaki disease; in addition, expiratory gas analysis of exercise testing can assess cardiorespiratory fitness in children and the operative results of congenital heart disease, etc.This article reviews the use of exercise testing in children with arrhythmias, cardiomyopathy, congenital heart disease, and Kawasaki disease.

Objective:To compare the efficacy and safety of endoscopic digestive resection and laparoscopic surgery in the treatment of gastric stromal tumor with diameter<3.5 cm.Methods:Stratified sampling was used to select 100 patients with diameter<3.5cm gastric stromal tumor from January 2018 to January 2020 in Yuncheng Central Hospital, and they were divided into two groups by touching the ball method.The control group (50 cases) was treated with laparoscopic surgery, and the observation group (50 cases) was treated with digestive endoscopic resection.The therapeutic effects of the two groups were compared.Results:The operative time of the observation group was (63.51±13.52)min, which was shorter than that of the control group [(71.24±15.04)min] ( t=2.703, P=0.004). The intraoperative blood loss in the observation group was (38.15±2.55)mL, which was less than that in the control group [(40.12±3.56)mL] ( t=3.181, P=0.001). The postoperative fasting time of the observation group was (20.02±3.85)h, which was shorter than that of the control group [(22.12±2.96)h] ( t=3.058, P=0.001). The postoperative recover defecation time of the observation group was (18.61±1.89)h, which was shorter than that of the control group [(20.05±3.13)h] ( t=2.785, P=0.003). The length of hospital stay in the observation group was (6.25±1.96)d, which was shorter than that in the control group [(7.06±1.16)d] ( t=2.515, P=0.007). The incidence of complications was 4.00% in the observation group, and 8.00% in the control group, the difference between the two groups was statistically significant(χ 2=0.177, P=0.673). There was no statistically significant difference in tumor risk classification between the two groups ( Z=0.386, P=0.534). Conclusion:Endoscopic digestive resection in the treatment of gastric stromal tumor with diameter<3.5cm has advantages of short operation time, less bleeding and fast postoperative recovery, etc., and has certain efficacy and safety.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.
