Objective To investigate the effect of liraglutide on the expression of NF-kappa B (NF-κB), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in renal tissue of insulin resistance rats. Method The rats were divided into 4 groups, control group ,high fat group ,liraglutide low dose group [100 μg/(kg· d)], liraglutide high dose group[100 μg/(kg·d)]. Detection of serum creatinine and urea nitrogen by automatic biochemical analyzer, and 24 h urine micro albumin was determined by immunoassay. The protein concentration of serum NF-κB,TNF-α and IL-6 was measured by ELISA. The expression of NF-κB,TNF-α and IL-6 mRNA in renal tissues was determined by RT-PCR. Results Compared with the control group, the serum creatinine, blood urea nitrogen,urinary protein, and the expression of NF-κB, TNF-α and IL-6 were significantly higher in high fat group, respectively (P < 0.05). The glomerular basement membrance thickening and foot process fusion were seen under electron microscope. Liraglutide high dose intervention can significantly reduce these changes. Conclusions Liraglutide can inhibit the expression of NF-κB,TNF-α and IL-6 in renal tissues of high fat induced insulin resistance rats,in a concentration dependent manner, which possibly improve renal function.

The authors first segment the right ventricle regions from the echocardiographics by introducig a seeded region growth algorithm. Then they reconstrunct the three dimensional data field of right ventricle by using rotary scanning interpolation algorithm. And then, the authors propose a layer-by-layer, row-by-row, and voxel-by-voxel approach based on the interpolation results to estimate the volume of right ventricle. Finally, some right ventricle functional parameters such as EDV (End-diastolic volume), ESV (End-systolic volume), and RVEF (Right ventricular ejection fraction) are computed according to the volume results. The volume variation curves of several patients during a cardiac cycle have been successfully plotted out. The obtained results are compared with those from Tomtec medial image workstation. The comparison indicates the proposed approach is practical and meaningful.

Objective:To investigate the application value of modified through-suture T-tube in laparoscopic biliary tract surgery.Methods:The retrospective and descriptive study was constructed. The clinical data of 15 patients with cholecystolithiasis and choledocholithiasis who underwent laparoscopic biliary tract surgery in China-Japan Friendship Hospital of Jilin University from January to December 2022 were collected. There were 8 males and 7 females, aged (49± 14)years. Of 15 patients, 8 cases undergoing laparoscopic cholecystectomy + common bile duct exploration and lithotomy+conventional T-tube drainage were set as conventional group and 7 cases undergoing laparoscopic cholecystectomy + common bile duct exploration and lithotomy+modified through-suture T-tube drainage were set as modified group. Observation indicators: (1) intraoperative and postoperative conditions; (2) follow-up. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers, and comparison between groups was conducted using Fisher exact probability. Results:(1) Intraoperative and postoperative conditions. Both groups of patients successfully completed the operation, with postoperative vital signs as stable, and no discomfort symptoms. There was no significant difference in duration of postoperative hospital stay between the coventional group and the modified group ( P>0.05). (2) Follow-up. Both groups of patients completed 30 days of postoperative outpatient follow-up. There was a significant difference in the sinus wall thickness between the coventional group and the modified group ( P<0.05). Among the 8 patie-nts in the conventional group, T tube was removed in the first 2 cases of patients after T tube angio-graphy 30 days after operation, and biliary fistula occurred in 1 of them and the drainage tube was re-indurated. For the other 6 cases, the time of T tube retention was extended to 6 weeks after surgery. After T tube angiography, the T tube was removed and no biliary fistula occurred. Among the 7 patients in the modified group, 2 cases with residual choledocholithiasis were found by T tube angiography 30 days after operation. After removal of T tube, percutaneous choledochoscopy was performed, in which the sinus wall was well formed and stone removal was smooth. The other 5 pati-ents were confirmed no residual calculi by T-tube angiography, and then the T-tube was removed, with no biliary fistula. Conclusion:Modified through-suture T-tube can be used in laparoscopic biliary tract surgery.

Objective To investigate the diagnosis and treatment of adult Hirschsprung disease. Methods The clinical data of 10 patients with adult Hirschsprung disease from August 2011 to August 2017 in the Department of General Surgery of the First Affiliated Hospital of Soochow University were retrospectively analyzed. Results Among the 10 patients, 4 cases were male, and 6 cases were female, with age 21 to 65 years old, and body mass index 16.77 to 25.73 kg/m2. The patients were diagnosed with Hirschsprung disease by postoperative pathological examination. All patients had difficult defecation medical history. Barium enema examination in 3 patients before operation showed obvious narrow segment, migrating segment and dilatation segment. Four cases received emergency surgical operation, and 6 cases received selective surgical operation. Complications included intestinal obstruction in 3 cases, incisions infection in 2 cases, and incision rupture in 1 case. Conclusions Adult Hirschsprung disease is difficult to be diagnosed, and the aspect of medical history, barium enema examination, surgical findings and pathological examination has to be combined. The surgery way of AHD is diverse and ought to be individual. Laparoscopic surgery with small trauma and quick recovery has great development space.

Objective: To investigate the immunity to mumps after administrating measles-mumps-rubella vaccine (MMR) among children aged 2-7 years old in Jiangsu province in 2015. Methods: A total of 4 190 healthy children aged 2-7 years old, living in local places for at least 3 months, and having been vaccinated at least 1 dose MMR were recruited to the study from Wujin district of Changzhou city, Gaogang district of Taizhou city and Ganyu district of Lianyungang city by using stratified cluster random sampling method between September and November, 2015. Those who did not accept MMR vaccination, who refused venous blood collection, who had affected mumps according to the memory of parents or teachers and who were diagnosed serious disease by clinical doctors were excluded from study. The self-designed questionnaire was used to collect the general information of the subjects and their MMR immunization history; and 0.5-2.0 ml of venous blood was collected from each subject. ELISA was used to detect the mumps antibody level in the serum of patients. Positive was defined as the antibody level ≥108 mU/ml, and negative as <108 mU/ml. χ² test was used to compare the difference in positive rates among subjects; and analysis of variance was used to compare the GMC changes in different time points after MMR vaccination. Results: Among 4 190 children, 2 280 were males (54.42%) and 1 910 were females(45.58%), and the positive rate of IgG antibody was 81.38% (3 344). There were 3 156 (95.18%) children vaccinated with one dose MMR, 187 (4.80%) children with two dose MMR, and 1 (0.02%) child with three dose MMR. The difference in positive rate of IgG antibody among different aged subjects showed statistical significance (χ²=58.61, P<0.001), the highest positive rate was in group of subjects aged 4-5 years old, at 89.43% (406/454), while the lowest positive rate was found among subjects aged 6-7 years old, at 75.63% (1 648/2 179). The positive rate after one dose of MMR vaccination was 79.14% (3 156/3 988), significantly less than it after two doses (93.03%, 187/201) (χ²=22.93, P<0.001). The GMC level at years<1, 1-<2, 2-<3, 3-<4, ≥4 following one dose MMR in the 3 988 children was 152.47, 227.78, 167.08, 126.91, 79.43 mU/ml, whose difference was statistically significant (F=51.29, P<0.001). Conclusion The sero-prevalence of IgG antibody in the children aged 2-7 years old in Jiangsu province was high. The positive rate among who received two doses MMR was significantly higher than it among who received just one dose, and the GMC level waned with times.

Objective:To evaluate the 1-year postoperative efficacy and nutritional indicators of single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) in obese patients.Methods:This retrospective observational study included patients with a body mass index (BMI) of ≥40.0 kg/m 2 regardless of other related metabolic diseases and patients with severe type 2 diabetes and a BMI between 27.5 and 40.0 kg/m 2. The clinical data of 66 obese patients who underwent SADI-S at the Bariatric and Metabolic Surgery Department of China-Japan Union Hospital of Jilin University from November 2018 to May 2022 were collected, including 53 cases of da Vinci robotic surgery and 13 cases of laparoscopic surgery. The patients comprised 38 men and 28 women with a median age of 35 (18–61) years and a mean preoperative BMI of 42.93 ± 6.82 kg/m 2. A total of 38 patients had type 2 diabetes, and 46 had hyperuricemia, 45 had hypertension, 35 had hyperlipidemia, 12 had hypercholesterolemia, and 12 had a high low-density lipoprotein (LDL) level. The main observation indicators were (1) intraoperative and postoperative conditions; (2) weight loss outcomes, including body weight, BMI, excess body weight loss (%EWL), and total body weight loss (%TWL) at 3, 6, and 12 months after surgery; (3) effects of treatment on metabolic disease; and (4) changes in nutrient indicators. Results:(1) Intraoperative and postoperative conditions: All patients successfully underwent SADI-S with neither conversion to laparotomy nor death. Four (6.1%) patients developed postoperative complications, and all of them recovered and were discharged after conservative or surgical treatment. (2) Weight loss outcomes: %EWL at 3, 6, and 12 months after surgery was 62.07 ± 26.56, 85.93 ± 27.92, and 106.65 ± 29.65, respectively, and %TWL was 22.67 ± 4.94, 32.10 ± 5.18, and 40.56 ± 7.89, respectively. Body weight and BMI 3 to 12 months after surgery were significantly lower than those before surgery (all P < 0.001). (3) Effect of treatment on metabolic disease: 3 to 12 months after surgery, fasting blood sugar, HbA1c, uric acid, systolic blood pressure, diastolic blood pressure, triglycerides, total cholesterol, LDL, and other indicators were significantly lower than those before surgery (all P < 0.05). Twelve months after surgery, the remission rates of diabetes, hyperuricemia, hypertension, hypertriglyceridemia, hypercholesterolemia, and high LDL were 100% (38/38), 65.2% (30/46), 62.2% (28/45), 94.3% (33/35), 100% (12/12), and 100% (12/12), respectively. (4) Changes in nutrient indicators: Compared with the preoperative nutrient levels, the hemoglobin and hematocrit levels were lower at 3 to 12 months after surgery, the total protein level was lower at 6 to 12 months after surgery, the albumin level was lower at 6 months after surgery, and the ferritin level was lower at 3 months after surgery. The differences were statistically significant (all P < 0.05). The incidence of anemia was 6.1% (4/66), hypoalbuminemia was 4.5% (3/66), and ferritin deficiency was 4.5% (3/66), all of which were improved or normalized through conservative treatment. Twelve months after surgery, 30 (45.5%) patients had vitamin A deficiency, 17 (25.8%) had vitamin E deficiency, 11 (16.7%) had folic acid deficiency, 2 had potassium deficiency (3.0%), 3 (4.5%) had calcium deficiency, 2 (3.0%) had magnesium deficiency, 9 (13.6%) had iron deficiency, and 16 (24.2%) had zinc deficiency. However, no relevant clinical symptoms occurred. Conclusions:SADI-S has a very significant effect on weight loss and alleviation of metabolic diseases. Nutrient deficiencies after SADI-S mainly involve vitamin A, vitamin E, zinc, and folic acid. The long-term efficacy and safety of SADI-S still need further follow-up observation.

Objective:To evaluate the mid-term efficacy of single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) in the treatment of obesity and type 2 diabetes mellitus.Methods:The cohort of this retrospective observational study comprised 118 obese patients with body mass index (BMI) ≥40 kg/m 2 with or without other related metabolic diseases and BMI of (27.5-40.0) kg/m 2 with type 2 diabetes mellitus (T2DM) who had been treated with SADI-S. Patients who had undergone modified surgery or been followed up for less than 1 year were excluded. Clinical data of the included patients [56 men and 62 women aged (34.5±9.7) years], who had undergone SADI-S in China-Japan Union Hospital, Jilin University from October 2018 to August 2022, were collected. Their mean preoperative body mass was (125.9±25.0) kg and BMI (42.8±6.8) kg/m 2. The 60 patients with T2DM had a mean fasting blood glucose of (9.9±3.2) mmol/L and HBA1c of (8.4±1.7) % before surgery. The main outcome measures were mid-term weight loss after surgery (body mass, BMI, excess weight loss, and total weight loss) 1, 2, 3, and 4 years after surgery and efficacy regarding diabetes mellitus (fasting blood glucose, glycated hemoglobin and diabetes remission rate at 1, 2, and 3 years after surgery). Outcomes were defined as follows. Complete remission: HbA1c <6% or fasting blood glucose <6 mmol/L without hypoglycemic medication; partial remission: HBA1c <6.5% or fasting blood glucose <7 mmol/L without hypoglycemic medication; significant improvement: HBA1c <7.0%, stable decrease of at least 1% compared with preoperative HBA1c, and postoperative dose of hypoglycemic medication significantly less; ineffective: no change in HBA1c and no reduction in dosage of hypoglycemic medication. Other outcome measures included intraoperative and postoperative adverse effects and postoperative nutritional indexes. Results:SADI-S was successful in all patients. There was no significant bleeding, conversion to open surgery, or perioperative death. The operation time was (186.1±41.5) minutes, and the postoperative hospital stay 6 (5–7) days. Surgical complications occurred in four patients, comprising peritoneal effusion, internal jugular vein thrombosis, anastomotic leakage, and gastric fistula. Body weight and BMI 1, 2, 3 and 4 years were significantly lower post- than pre-operatively (all P<0.05). Excess weight loss was (81.9±16.2) %, (82.2±15.5) %, (88.3±20.1) %, and (83.2±18.1) % at 1, 2, 3, and 4 years postoperatively, respectively. Total weight loss was (39.7±8.7) %, (40.6±10.6) %, (42.2±11.5) % and (45.4±10.2) %, respectively. The mean fasting blood glucose concentrations of the 60 patients with T2DM were (5.1±1.0) mmol/L, (5.0±0.7) mmol/L, and (5.4±0.9) mmol/L 1, 2 and 3 years postoperatively, respectively. The values for glycosylated hemoglobin were (4.9±0.6) %, (4.8±0.5) %, and (5.1±0.8) %, respectively, all of which are significantly lower than preoperatively (all P<0.05). The complete remission rate of diabetes was 95.0% (38/40), 90.0% (36/40), and 9/13 1, 2, and 3 years postoperatively, respectively. Additionally, the partial remission rate and significant improvement rate were both 100%. Two years postoperatively, the incidence of anemia was 27.8% (10/36), of hypoproteinemia 11.8% (4/34), and of ferritin deficiency 25.8% (8/31), all of which were improved by conservative treatment such as blood transfusion, iron supplementation, and adjustment of diet. Conclusion:SADI-S has a significant mid-term beneficial effect on weight loss and diabetes remission status in patients with obesity and type 2 diabetes.

Objective:To evaluate the complications of complex intracranial aneurysms after intervention with flow-diverter (FD) devices.Methods:Sixty patients with complex intracranial aneurysms accepted FD devices in Department of Cerebrovascular Diseases, Second Affiliated Hospital of Guilin Medical University from July 2018 to June 2021 were chosen. Clinical and imaging data of these patients were retrospectively analyzed, and complications were recorded: procedure-related adverse events, early postprocedural complications, complications during follow-up, and covered branch occlusion.Results:A total of 61 FD devices (47 Pipeline Flex, 10 Tubridge, 4 Surpass Streamline) were implanted in 60 patients. Incidence of procedure-related adverse events was 8.3% (5/60), including 3 with incomplete stent apposition, 1 with intraoperative bleeding, 1 with aneurysm neck not covered by stent; incidence of early postprocedural complications was 6.7% (4/60), including 3 with hemorrhagic complication and 1 with ischemic complication. DSA follow-up ([22.7±16.8] months) was completed in 54 patients; aneurysm healed rate was 83.3% (45/54). First DSA follow-up 6 months after surgery showed that in-stent restenosis was 7.4% (4/54), of which 2 deteriorated to parent vessel occlusion at 2- and 3-year after procedure, respectively. A total of 78 branch arteries were covered by FD devices, and only 1 (1.3%, 1/78) demonstrated branch artery occlusion at last follow-up, without clinical symptoms.Conclusion:The complications of complex intracranial aneurysms after intervention with FD devices should be recognized; incomplete stent apposition is the main procedure-related adverse event, and hemorrhagic complication mainly appear in the early postprocedural period; in-stent restenosis should be vigilant during follow-up.

Objective To investigate the effect of colquhounia root tablet(CRT)on hyperglucose-in-duced epithelial-mesenchymal transition(EMT)in renal tubular epithelial cells(HK-2),and to explore its possible action mechanism.Methods HK-2 was cultured in vitro,and HK-2 was divided into the following five groups:control group(CON group),hyperosmolar group(MA group),high glucose group(HG group),high sugar+CRT group(HG+CRT group),high sugar+phosphatidylinositol 3 kinase inhibitor group(HG+LY29400 group),high sugar+CRT+phosphatidylinositol 3 kinase inhibitor group(HG+CRT+LY29400).The real time immunofluorescence quantitative PCR(qPCR)was used to detect the mRNA ex-pression levels of E-cadherin,α-smooth muscle actin(α-SMA)and phosphatase and tensin homolog(PTEN)in each group.Western-blot was used to detect the protein expression levels of PTEN,phosphatidylinositol 3 kinase(PI3K),protein kinase B(Akt),phosphorylated protein kinase B(p-Akt),E-cadherin and α-SMA in each group.Results Compared with the CON group,the protein and mRNA expression levels of α-SMA,p-Akt protein expression level and p-Akt/Akt ratio in the HG group were increased,the protein and mRNA ex-pression levels of E-cadherin and PTEN were decreased,and the differences were statistically significant(P＜0.05).Compared with the HG group,the α-SMA protein and mRNA expression levels in the HG+CRT group were decreased,while the E-cadherin protein and mRNA expression levels were increased,and the differences were statistically significant(P＜0.05).Compared with the HG+CRT group,there was no significant differ-ence in the E cadherin,α SMA,PTEN,P13K and Akt protein expression levels and p-Akt/Akt ratio in the HG+CRT+LY29400 group had no significant differences(P＞0.05).while the expression level of p-Akt protein was increased,and the difference was statistically significant(P＜0.05).Conclusion In vitro,CRT could re-verse hyperglucose-induced renal tubular epithelial cell EMT via the PTEN/PI3K/Akt signaling pathway.

Objective:To evaluate the 1-year postoperative efficacy of four bariatric procedures, namely sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S), and biliopancreatic diversion with duodenal switch (BPD/DS) for treating super obesity.Methods:In this retrospective observational study, we analyzed the clinical data of 40 patients with super obesity (body mass index [BMI]≥50 kg/m 2) who had undergone bariatric surgery in the China-Japan Union Hospital of Jilin University from November 2015 to December 2020. The study cohort consisted of 21 men and 19 women of average age 31.7±9.0 years. The preoperative weight and BMI were (159.2±16.9) kg and (53.4±3.0) kg/m 2, respectively. Prior to the surgery, 30 individuals had hypertension, 27 hyperuricemia, 15 type 2 diabetes, 10 abnormally high total cholesterol, 20 abnormally high triglycerides, and 24 abnormally high low-density lipoprotein. We divided the participants into four groups according to the type of operation: SG group ( n=16), RYGB group ( n=9), SADI-S group ( n=9) and BPD/DS group ( n=6). We examined the following factors: weight, BMI, excess weight loss (%), total weight loss (%), and remission of preoperative metabolic diseases (including hypertension, hyperuricemia, type 2 diabetes, and hyperlipidemia) 3, 6, and 12 months after surgery. The variables assessed for hypertension were systolic and diastolic blood pressure; for type 2 diabetes, glycated hemoglobin; and for hyperlipidemia, total cholesterol, triglycerides, and low-density lipoprotein 1-year after the surgery. The safety of surgery was also assessed. Results:All patients successfully completed laparoscopic procedures, none of them requiring conversion to laparotomy. The amount of blood loss during surgery was less than 50 mL. Postoperative hospital stay was 6–16 days. There were no deaths during the perioperative period. However, two postoperative complications occurred in the RYGB group, namely bleeding and anastomotic leakage. No complications were detected in the other groups. At 3, 6, and 12 months after surgery, percentage of excess weight loss was 36.6±11.0, 62.4±15.7, and 68.2±16.0 ( F=21.830, P<0.001) in the SG group; 30.6±6.9, 42.5±5.8, and 50.6±11.1 ( F=13.222, P<0.001) in the RYGB group; 39.7±7.8, 54.6±12.7, and 81.9±12.0 ( F=33.821, P<0.001) in the SADI-S group; and 40.2±4.8, 57.7±11.8, and 82.8±14.9 ( F=21.552, P<0.001), respectively, in the BPD/DS group. The percentage of excess weight loss increased significantly over the 12-month observation period in all groups . Compared with before surgery, hypertension and hyperuricemia in the SG, SADI-S, and BPD-DS groups showed significant improvement after one year (all P<0.05). However, only the SADI-S group exhibited a significant decrease in glycosylated hemoglobin concentrations ( P=0.038). Only the BPD-DS group showed significant decreases in various indicators of hyperlipidemia (all P<0.05). The improvements in obesity-related complication indexes did not reach statistical significance in the RYGB group (all P>0.05). Conclusion:SG, RYGB, SADI-S and BPD/DS are all safe and effective treatments for super obesity. All of these procedures can improve the associated metabolic diseases to a certain extent.
