ABSTRACT
Objective:To investigate the influence of perioperative oral nutritional supple-mentation on short-term efficacy of laparoscopic sleeve gastrectomy (LSG) for obesity patients.Methods:The prospective study was conducted. The clinical data of 218 obesity patients who underwent LSG in the General Hospital of Ningxia Medical University from January 2018 to December 2021 were selected. Patients receiving perioperative oral nutritional supplementation were allocated into the experiment group, and patients receiving perioperative conventional treatment were allo-cated into the control group, respectively. Observation indicators: (1) grouping situations of the enrolled patients; (2) postoperative situations and follow-up; (3) nutrition related indicators; (4) dietary compliance; (5) weight loss related indicators. Follow-up was conducted using telephone interview, WeChat communication and outpatient examination to detect albumin (ALB), hemoglobin (HB), dietary compliance and weight loss related indicators of patients up to February 2022. Patients were followed up once every 30 days after discharge. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the indepen-dent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Comparison of ordinal data was analyzed using the rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 218 patients were selected for eligibility. There were 42 males and 176 females, aged (32±9)years with body mass index (BMI) as (39±7)kg/m 2. Of the 218 patients, there were 109 patients in the experiment group and 109 patients in the control group. Gender(male, female), age, BMI, preoperative albumin (Alb), preoperative hemoglobin (Hb) were 17, 92, (33±9)years, (39±7)kg/m 2, (40.6±4.8)g/L, (141.7±13.9)g/L in the experiment group, versus 25, 84, (31±8)years, (39±8)kg/m 2, (40.9±4.2)g/L, (142.9±9.7)g/L in the control group, showing no signifi-cant difference in the above indicators between the two groups ( χ2=1.89, t=?1.52, 0.51, 0.40, 0.71, P>0.05). (2) Postoperative situations and follow-up. The duration of initial hospital stay, the cost of initial hospital stay were (9.1±2.9)days, (3.6±0.5)ten thousand yuan in the experiment group, versus(11.6±3.7)days, (4.9±1.0)ten thousand yuan in the control group,showing significant differences in the above indicators between the two groups ( t=5.58, 12.38, P<0.05). Of the 218 patients,119 patients were followed up,including 62 patients in the experiment group and 57 patients in the control group,with the follow up time as 31.0(range, 25.0?38.0)days.

ABSTRACT
Objective:To observe early postoperative changes in body composition in patients receiving laparoscopic sleeve gastrectomy (LSG) and to explore the relationship between body composition and glycolipid metabolism, so as to provide stage-specific information for doctors in the weight loss team on metabolic surgery effect assessment and postoperative follow-up and guidance.Methods:The study was a retrospective cohort study. According to inclusion and exclusion criteria, a total of 44 patients who underwent LSG in the Department of Gastrointestinal Surgery, General Hospital of Ningxia Medical University from December 1, 2017 to May 30, 2021 were included. Body composition was measured using bio-electrical impedance analysis at baseline and after surgery.Results:The patients' body composition changed significantly at 1 month and 3 months after surgery, and glucose and lipid metabolism indicators improved significantly. Body composition indicators, including body mass index (BMI), the amount of moisture in the body, inorganic salts, body fat, skeletal muscle mass, fat free mass, body fat percentage, waist-to-hip fat ratio, visceral fat, basal metabolic rate and bone mineral content, decreased significantly within 3 months after surgery ( P<0.05). The ratio of upper and lower limb muscle to body weight (U/W, L/W) increased significantly after surgery ( P<0.05). The ratio of trunk muscle to body weight (T/W) decreased within 3 months after surgery ( P<0.05). Pearson and Spearman correlation analyses showed that skeletal muscle mass and U/W were positively correlated with triglyceride ( r=0.637 and 0.304, respectively, both P<0.05) in 3 months after operation. L/W was positively correlated with fasting blood glucose ( r=0.454, P<0.05). T/W was negatively correlated with triglyceride ( r=-0.643, P<0.05). Conclusions:Patients undergoing LSG displayed significant changes in body composition in the early postoperative period. Changes in muscle mass of different body parts varies and showed different effects on glucose and lipid metabolism parameters. The trunk muscle mass is negatively correlated with glucose and lipid metabolism indicators, while limb muscle mass and skeletal muscle mass are positively. It is suggested that the changes of body composition in different parts should be observed when evaluating patient outcomes after LSG and the trunk body mass should be preserved as far as possible.
ABSTRACT
Objective To explore the effect of sucralfate on cytokines in rats with paraquat (PQ) poisoning. Methods Seventy-two healthy male Sprague-Dawley (SD) rats were randomly divided into PQ model group, sodium bicarbonate intervention group (SB group) and sucralfate suspension gel group (LTL group), with 24 rats in each group. The rat model of PQ poisoning was reproduced by one-time intragastric administration of PQ solution 25 mg/kg. The rats in SB group and LTL group were intragastricly administrated with 5 mL·kg-1·d-1of 100 g/L sodium bicarbonate or 200 g/L sucralfate at 2 hours after exposing to PQ, and the rats in PQ model group were given the same amount of sterile saline. The abdominal aortic blood of rats was collected at 1, 3, 6, and 10 days after PQ poisoning, and the levels of serum tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10) and transforming growth factor-β1 (TGF-β1) were determined by enzyme-linked immunosorbent assay (ELISA). The left lung tissue was harvested, and lung wet/dry weight (W/D) ratio was assessed. Results With prolonged exposure, lung W/D ratios in all the groups were increased gradually, reached the peak at 10 days, but in the SB group and LTL group, the amplitude of increase was obviously reduced, the ratios were significantly decreased at 6 days and 10 days as compared with those in PQ model group (SB group vs. PQ model group: 4.99±0.79 vs. 6.98±0.86 at 6 days, 5.61±0.36 vs. 7.36±0.95 at 10 days; LTL group vs. PQ model group: 4.61±0.24 vs. 6.98±0.86 at 6 days, 4.24±0.20 vs. 7.36±0.95 at 10 days, all P < 0.05), but there was no significant difference between SB group and LTL group (all P > 0.05). After PQ poisoning, the levels of TNF-α, IL-10 and TGF-β1 were elevated, and reached the peak at 3 days and then decreased gradually. Compared with the PQ model group, serum TNF-α, IL-10 and TGF-β1 levels in SB group and LTL group were decreased significantly [SB group vs. PQ model group: 3-day TNF-α (ng/L) was 147.6±12.3 vs. 168.2±11.3, 3-day IL-10 (ng/L) was 65.4±3.2 vs. 115.1±9.2, 3-day TGF-β1 (ng/L) was 356.3±50.3 vs. 415.6±68.3; LTL group vs. PQ model group: 3-day TNF-α (ng/L) was 82.2±7.4 vs. 168.2±11.3, 3-day IL-10 (ng/L) was 44.4±5.2 vs.115.1±9.2, 3-day TGF-β1 (ng/L) was 296.3±40.2 vs. 415.6±68.3, all P < 0.05], especially in LTL group (all P < 0.05). Conclusion Early gastrointestinal lavage with sucralfate could effectively reduce the inflammatory exudation in lung tissue after PQ poisoning, and inhibit the cytokine secretion.
ABSTRACT
OBJECTIVE: This study explored the effects of sucralfate intervention as a novel treatment for paraquat (PQ) poisoning in Sprague-Dawley (SD) rats. METHODS: After PQ poisoning, the SD rats were randomly divided into the PQ control group (treated with normal saline), the sodium bicarbonate (SB) treatment group, and the sucralfate (LTL) treatment group. Then, the rats were administered normal saline, sodium bicarbonate solution, or sucralfate suspension as an intervention by gastric lavage. At 1, 3, 6, and 10days after poisoning, the left lungs of some rats were removed to determine the lung wet/dry (W/D) weight ratio. Additionally, the serum cytokine levels were measured, and the lung and kidney tissues were pathologically examined. RESULTS: After treatment, the signs and symptoms of the rats were improved, the mortality rate was reduced, the W/D weight ratio of the lung was lower, the cytokine levels [transforming growth factor (TGF)-ß1, interleukin (IL)-10, and tumor necrosis factor (TNF)-α] were decreased, and the pathological injuries of the lungs and kidneys were improved. Moreover, sucralfate was significantly more effective than the control (normal saline) group and the SB treatment group. CONCLUSION: The results showed that early gastrointestinal lavage with sucralfate effectively reduced the inflammatory response and lung and kidney injuries and improved the survival of the SD rats.

ABSTRACT
More and more DNA sequences have been obtained since the start-up of human genome project. Powerful system is badly needed for data mining on these DNA sequences. Based on a personal computer and Linux operating system, the Phred/Phrap/Consed software and Blast software were used to construct a platform for batch analysis of the sequences, including identifying raw DNA sequence from chromatogram file, vector sequence removing, contig analysis (sequence assembly), repeat sequence identifying and sequence similarity analysis. Result demonstrated that this robust platform could accelerate data analysis for large-scale DNA sequencing.
