OBJECTIVE:To observe the clinical efficacy and safety of Shuanghuanglian oral liquid combined with cefuroxime axetil in the treatment of bacterial respiratory tract infection. METHODS:184 patients with bacterial respiratory tract infection were randomly divided into test group and control group. Test group was orally given 250 mg Cefuroxime axetil tablet,twice a day+20 ml Shuanghuanglian oral liquid,3 times a day. Control group was only given Cefuroxime axetil tablet (the same dosage as test group). The treatment course for 2 groups was 2 weeks. The cough duration,body temperature recovery time and runny nose disap-pearing time before and after treatment and bacterial clearance rate in 2 groups were observed,clinical efficacy and incidence of ad-verse reactions were recorded. RESULTS:After treatment,the total effective rate in test group was significantly higher than control group,cough duration,body temperature recovery time and runny nose disappearing time were significantly shorter than control group,the differences were statistically significant(P<0.05);and there were no significant differences in the bacterial clearance rate and incidence of adverse reactions(P>0.05). CONCLUSIONS:The efficacy of Shuanghuanglian oral liquid combined with ce-furoxime axetil is superior to cefuroxime axetil alone in the treatment of bacterial respiratory infections,with similar safety.

Objective To investigate the efficacy of micro?surgery for the treatment of medulla oblongata cavernomas. Methods A retrospective analysis was conducted on the clinical data of 21 patients with cavernous hemangioma who received micro?surgical treatment. Of the 21 patients, 13 were men and 8 women,aged 22 to 63 years. The preoperative Karnofsky performance status(KPS)score was 76.5 ± 10.2. The main clinical manifestations included sensory disorder and difficulty swallowing etc. According to the location of the lesions ,the posterior transchoroidal fissure approach was employed for 16 patients;far?lateral approach,5 patients. Electrophysiological monitoring and nervous system navigation were supple?mentarily adopted in both types of surgery. Further ,KPS scoring was conducted to evaluate the patients 'quality of life. Results The medulla cav?ernous hemangioma was excised in all cases. For 17 patients with primary neurological disorders ,their symptoms were alleviated or resolved;4 pa?tients had severe symptoms and 8 presented with new clinical symptoms. A follow?up visit was conducted 8 to 97 months post?surgery(average 47.6 months). All patients were found capable of caring for themselves in daily life and performing simple or normal learning and working activities without recurrence or bleeding. The mean postoperative KPS score was 83.7 ± 15.5. Conclusion Patients with medulla cavernous hemangioma bleeding or severe symptoms should actively seek surgical treatment. Repeated bleeding is the absolute indication for surgery. Surgical skills ,elec?trophysiological monitoring,and nervous system navigation can reduce nervous system damage and protect the brainstem. The patient's quality of life is expected to significantly improve after surgery.

Objective:To investigate the efficacy and safety of cortical-sparing adrenalectomy (CSA) in the treatment of bilateral pheochromocytoma.Methods:The clinical data of 20 patients with bilateral pheochromocytoma treated in Xiangya Hospital of Central South University from January 2004 to December 2019 were analyzed retrospectively, including 10 males and 10 females. The average age of onset was 32.5 (8-51) years. 3 cases had a family history of pheochromocytoma. There were 14 and 6 patients with bilateral synchronous and metachronous onset, respectively. The mean value of vanilmandelic acid (VMA) in 20 cases was (106.4 ± 60.0) μ mol/24h. Preoperative enhanced CT showed a soft tissue mass with uneven enhancement in the adrenal region, with low-density necrosis, which suggested the diagnosis of Pheochromocytoma. All 20 cases underwent CSA under general anesthesia. In 14 cases of bilateral synchronous disease, 9 cases underwent simultaneous operation and 5 cases underwent staged operation; 6 patients with metachronous disease underwent bilateral tumor resection successively. Laparoscopic surgery was performed in 18 cases and open surgery in 2 cases. Through the abdominal or retroperitoneal approach, open the fat capsule around the upper pole of the kidney, free the medial edge of the upper pole of the kidney, expose the adrenal gland and tumor, completely remove the tumor and capsule, ensure that the adrenal tissue is 3-5 mm away from the cutting edge of the tumor, and the reserved cortical size is at least 1 / 3 of the ipsilateral adrenal gland. The central adrenal vein was preserved as much as possible to reduce the damage to the adrenal vascular bed. The operation related data, intraoperative monitoring records, postoperative complications and long-term follow-up results were recorded.Results:All the 20 cases were successfully completed without tumor rupture. The operation time of simultaneous operation and staged operation were (242.3 ± 61.0) min and (137.9 ± 60.3) min, respectively. The number of patients admitted to ICU after operation was 7 and 2, respectively ( P<0.05); The intraoperative bleeding volume was (528.6 ± 355.7) ml and (277.8 ± 264.7) ml, the number of blood transfusion cases were 5 and 2 cases, and the average hospital stay was (7.4 ± 2.0) d and (7.8 ± 3.3) d, respectively ( P>0.05). 20 cases took glucocorticoid orally (prednisone 5 mg, once every 12 hours) after operation. There was no obvious manifestation of adrenocortical dysfunction and Addison's crisis. The hormone was stopped gradually from 2 weeks to 1 month after operation. The average follow-up was 5.4 (1.0-16.0) years. There were 3 cases of recurrence and no metastasis. Gene detection was performed in 10 cases after operation, and 7 cases carried pheochromocytoma RET and VHL pathogenic gene mutations (RET in 2 cases and VHL in 5 cases). Conclusion:Although CSA has a certain risk of recurrence, it avoids hormone replacement and does not increase the risk of metastasis and death. It is recommended for the treatment of hereditary pheochromocytoma, especially bilateral pheochromocytoma.

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 evaluate the clinical application of early total care (ETC) for polytrauma patients combined with thoracolumbar fractures.Methods A retrospective case control study was conducted to analyze the clinical data of 137 polytrauma patients combined with thoracolumbar fractures admitted to the First Affiliated Hospital of Soochow University and the Third People's Hospital of Zhang,jiagang from January 2012 to October 2015.There were 90 males and 47 females,aged 26-69 years,with an average age of 48.2 years.The patients were divided into ETC group (n =59) and TMC group (n =78).In the ETC group,physicians from different departments evaluated the patients and developed individualized therapeutic regimens to allow the patients to undergo surgery at early stage after injury.The TMC group preferentially stabilized the patient's condition or transferred the patients to specialist treatment,and then the surgery was performed electively after the condition of the patient was stable.The ISS of the ETC group was (22.15 ± 9.28)points,and that of the TMC group was (23.37 ± 10.74) points.All patients underwent conventional posterior pedicle screw internal fixation.For patients with burst fracture and nerve injury,posterior spinal canal decompression was performed.The thoracolumbar injury classification and severity score (TLICS),spinal load sharing classification (LSC),preoperative and postoperative Glasgow coma score (GCS),Frankel classification,hospitalization time and postoperative complications were compared between the two groups.Results The TLICS scores of ETC group were significantly lower than those of TMC group (P ＜ 0.05) while the LSC scores showed no significant differences between the two groups (P ＞ 0.05).ETC group had shorter hospitalization time [(11.8 ± 3.7)days ∶ (17.5 ±4.5)days] and lower pressure ulcer incidence [(5％ ∶ 21％)] than the TMC group (P ＜ 0.05 or 0.01),but the former had significantly higher wound infection rate [(17％ ∶ 15％)] (P ＜ 0.05).There was no significant difference in pulmonary infection and deep venous thrombosis incidence between the two groups (P ＞ 0.05).No significant differences were found in the preoperative GCS scores between the two group (P ＞ 0.05) while the postoperative GCS scores of TMC group were higher than those of ETC group (P ＜ 0.01).Postoperative GCS scores in both groups were significantly higher than their preoperative GCS (P ＜ 0.05).The results of postoperative Frankel classification in the ETC group were as follows:Grade A in one patient,Grade B in one,Grade C in three,Grade D in four and Grade E in two patients,with an improvement rate of 82％.The results of postoperative Frankel classification in the TMC group were as follows:Grade A in three patients,Grade B in three,Grade C in three,Grade D in four and Grade E in four,with an improvement rate of 65％.Conclusions For polytrauma patients combined with thoracolumbar fractures,ETC can shorten hospitalization time,reduce the pressure ulcer incidence,and better facilitate the recovery of nerve function,yet with higher wound infection risk compared with TMC.TMC was preferred subjectively for patients with unstable thoracolumbar fractures and high TLICS.

Objective:To investigate the correlation between paraspinal muscle atrophy, morphological changes of facet joints and adjacent segment disease (ASDis) after lumbar fusion operation.Methods:A retrospective study was conducted among 195 patients who underwent posterior lumbar fusion again for ASDis at this institution from January 2014 to December 2020, including 29 patients with ASDis whose initial surgical fusion segment was L 4,5. According to Roussouly's staging, there were 5 cases of type I, 9 cases of type II, 10 cases of type III, and 5 cases of type IV. Another 29 cases were selected from patients without ASDis after lumbar fusion as a control group. The control group was paired 1∶1 with the ASDis group according to gender, fusion segment, and Roussouly typing of the lumbar spine. The cross-sectional area (CSA) and fat infiltration (FI) of paravertebral muscle, facet joint angle (F-J) and pedicle facet (P-F) angle before the first (second) operation were measured and compared between the two groups. Then logistic regression analysis was used to determine the predictors of ASDis after posterior lumbar fusion. Finally, the receiver operation characteristic (ROC) curve was described, and the area under the curve (AUC) and cut-off point were calculated. At the same time, the paraspinal muscle atrophy before the second operation in ASDis group was measured. Results:The average follow-up time of 98 patients was 59.25±6.38 months (range, 49-73 months). The average body mass index (BMI) of ASDis group was 24.76±3.64 kg/m 2, which was higher than that in control group (22.24±2.92 kg/m 2) ( t=2.481, P=0.041). The average CSA and relative cross-sectional area (rCSA) of paraspinal muscle in ASDis group were 3 214.32± 421.15 mm 2 and 1.69±0.36 respectively, which were less than 3 978.91±459.87 mm 2 and 2.26±0.29 in control group ( t=10.22, P=0.012; t=9.47, P=0.038). The FI degree of paraspinal muscle in ASDis group (21.95%±5.89%) was significantly higher than that in control group (14.64%±7.11%) ( t=7.32, P=0.002). The F-J angle in ASDis group was 35.06°±3.45°, which was less than 38.39°±4.67° in control group ( t=4.76, P=0.027). The P-F angle in ASDis group was 117.39°±8.13°, which was greater than 111.32°±4.78° in control group ( t=5.25, P=0.031). Multivariate logistic regression analysis showed that higher BMI ( OR=1.34, P=0.038), smaller rCSA of paraspinal muscle ( OR=0.02, P=0.017) and higher FI of paraspinal muscle ( OR=1.58, P=0.032) were the risk factors of postoperative ASDis. The ROC curve showed that the AUC of BMI was 0.680 and the cut-off point was 22.58 kg/m 2; The AUC of the FI of paraspinal muscle was 0.716 and the cut-off point was 15.69%; The AUC of rCSA of paraspinal muscle was 0.227 and the cut-off point was 1.92. For ASDis patients, the paraspinal muscle before the second operation had a higher degree of FI (25.47%±6.59% vs. 21.95%±5.89%, t=3.99, P=0.042) and a smaller rCSA (1.52±0.28 vs. 1.69±0.36, t=3.85, P=0.038) than that before the first operation. The difference between the FI degree of paraspinal muscle before the second operation and the first operation was negatively correlated with the occurrence time of ASDis ( r=-0.53, P=0.039) , and the difference of rCSA was positively correlated with the occurrence time of ASDis ( r=0.64, P=0.043) . Conclusion:When BMI >22.58 kg/m 2, FI of paraspinal muscle >15.69%, and rCSA of paraspinal muscle <1.92, it suggests that ASDis is more likely to occur after operation. And the more obvious paraspinal muscle atrophy after the first operation, the earlier ASDis may occur. Morphological changes of facet joints cannot be used as an index to predict the occurrence of ASDis.

Objective:To explore the changes of dynamic cerebral autoregulation ability in pilots exposed to acute positive acceleration(+ Gz) by transcranial Doppler combined with beat-to-beat blood pressure.Methods:A total of 26 pilots enrolled in the + 8Gz manned centrifuge trial at the Air Force Medical Center, Air Force Medical University from June to October 2022 were prospectively included. Blood pressure and heart rate were monitored in the resting state before the trial and within 5 min after centrifugation. Transcranial Doppler combined with noninvasive continuous beat-to-beat blood pressure monitor were used to detect bilateral middle cerebral artery blood flow velocity and beat-to-beat pulse pressure respectively. The transfer function analysis was applied to derive the parameters of cerebral blood flow autoregulation in each frequency band from 0.02 to 0.50 Hz, and the phase, gain and coherence were calculated. The above parameters were compared between resting state and after acute + 8Gz positive acceleration exposure.Results:Compared with the resting state, in all of the 26 pilots after acute + 8Gz positive acceleration exposure, the systolic and diastolic blood pressure and heart rate increased significantly ( P<0.001), the phase significantly increased and the gain significantly decreased in the ultra-low frequency band (0.02-0.07 Hz) ( P<0.05); whereas there were no statistical differences of gain and phase in the low frequency band (0.07-0.20 Hz) and the high frequency band (0.20-0.50 Hz) (all P>0.05). Conclusions:Transcranial Doppler combined with beat-to-beat pulse pressure can be used for the assessment of changes in immediate dynamic cerebral autoregulation after acute + Gz exposure, and transfer function analysis of ultra-low frequency band parameters is suitable for this type of evaluation.

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.

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.
