Objective:To compare the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) combined with sharp His angle reconstruction (LSG-His) versus traditional LSG.Methods:In this retrospective cohort study we collected clinical data of patients with obesity who had undergone LSG or LSG-His in the Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University, from January to June 2022. After excluding patients with incomplete follow-up data and those with hiatal hernia, 83 obese patients, of which 39 who had undergone LSG (LSG group) and 44 who had undergone LSG-His (LSG-His group), were included in the study. The basic steps in LSG-His are the same as in conventional LSG. After continuous suturing of the gastric staple line, one stitch is placed between the proximal side of the gastric greater curvature staple line and the proximal side of the gastric fundus posterior wall with the left diaphragm, and another stitch between the right side of the gastric fundus and the esophagus, reconstructing the sharp His angle. Clinical data, postoperative complications, and follow-up data on weight loss and gastroesophageal reflux disease (GERD) symptoms 1-, 3-, 6-, and 12-months post-discharge were compared between the two groups. GERD symptoms were assessed using the Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire.Results:There were no significant differences between the two groups in baseline characteristics, length of hospital stay, hospitalization costs, intraoperative bleeding, postoperative nausea and vomiting, dysphagia, or postoperative complications (all P>0.05). Compared with the LSG group, the LSG-His group had significantly longer operative times (92 [80, 100] minutes vs. 80 [70, 100] minutes, U=2.227, P=0.026), higher postoperative 24-hour pain scores (5.2±1.8 vs. 4.3±1.9, t=-2.065, P=0.041), and higher rates of morphine use (70.5% [31/44] vs. 46.2% [18/39], χ2=4.519, P=0.025). The incidence of new-onset GERD 12 months postoperatively was significantly lower in the LSG-His than the LSG group (10.7% [3/28] vs. 61.3% [19/31], χ2=14.00, P<0.001). According to changes in Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire scores, the LSG-His group also had significantly lower rates of exacerbation of GERD (2/16 vs. 5/8, χ2=4.27, P=0.021) and higher rates of GERD remission (12/16 vs. 2/8, χ2=3.62, P=0.032) than did the LSG group. Additionally, excess weight loss rates were significantly higher in the LSG-His group at 3 months [(54.7± 18.7)% vs. (46.5±15.0)% , t=-2.166, P=0.033], 6 months [(73.8±24.7)% vs. (64.0±19.1)% , t=-2.018, P=0.047], and 12 months [(82.9±26.7)% vs. (72.2±19.3)%, t=-2.063, P=0.042] than in the LSG group. Conclusion:Compared with LSG, LSG-His is safe and feasible and achieves better short-term control of postoperative GERD and more effective weight loss. Further large-scale, long-term, prospective studies are needed to confirm the long-term efficacy of LSG-His.

Objective:To investigate the relationship of osteoporotic vertebral body compression fracture(OVCF)with multifidus muscle and intervertebral disc degeneration in the lower lumbar spine and the lumbar-pelvic parameters in elderly women.Methods:Clinical data of a total of 108 elderly women with osteoporosis were retrospectively analyzed.They were divided into the fracture group(n=56)and the control group(n=52)according to the presence of vertebral body compression fractures.Age, body mass index(BMI)and bone mineral density(BMD)were collected in two groups.The angle of pelvic incidence(PI), angle of pelvic tilt(PT), low lumbar lordosis(LLL)and sacral slope(SS)were measured by the standing lumbar lateral X-ray photography.The degree of degeneration of intervertebral disc L 3-S 1 and multifidus muscle were detected by using the lumbar MRI.These parameters were compared between the two groups. Results:The age, BMI and BMD had no significant difference between the two groups( P>0.05). The degree of intervertebral disc degeneration of L 3-L 4 and L 4-L 5 was statistically significant higher in the fracture group than in the control group( Z=-4.656 and -2.675, P=0.000 and 0.007), while the degree of intervertebral disc degeneration of L 5-S 1 had no statistically significant difference between the two groups( Z=-1.784, P=0.075). There were statistically significant higher multifidus muscle degeneration of L 3-L 4 and L 4-L 5 in the fracture group than in the control group( Z=-3.248 and -4.073, P=0.001 and 0.000), while no significant difference between the two groups in multifidus muscle degeneration of L 5-S 1( Z=-1.096, P=0.282). No statistically significant differences were found in PI, PT, SS and LLL between the two groups( t=1.162, 0.827, -0.082 and -0.677, P=0.248, 0.410, 0.935 and 0.500). Conclusions:The degeneration of intervertebral disc and multifidus muscle of L 3-L 4 and L 4-L 5 is positively correlated with OVCF in elderly women.

Objective To discuss the feasibility and the effects of percutaneous vertebroplasty (PVP) in the treatment of the osteoporotic compression fracture in theupper and middle thoracic vertebrae.Methods The study included 101 patients.55 cases were treated with PVP (observation group) and 46 cases were treated with conservative treatment (control group).The clinical efficacy of those two different treatment methods was evaluated by the changes of VAS score,ODI score,vertebral height and Cobb angle before versus after treatment.Results VAS and ODI scores at 48 hours and 6 weeks after treatment was significantly lower in observation group than in the control group (all P＜0.05).Although there was no significant difference in VAS and ODI scores between the two groups after 6 months of treatment (both P＞0.05),the anterior and middle vertebral height was decreased and Cobb angle of spine was increased in control group as compared with observation group (both P＜ 0.05).Conclusions PVP is an effective and safe method in the treatment of osteoporotic vertebral compression fractures in upper and middle thoracic vertebrae.The short-and long-term evaluation indexes are better in PVP than in conservative treatment.But the surgery should be proceeded under highly clear perspective equipment by the surgeons with highly level professional technology.Because the surgery is highly risky,surgery should be proceeded with cautions.

Objective To observe the fusion rate by using cage filled with osteophyte in anterior cervical disectomy and fusion.Methods From January 2010 to July 2012,81 patients receiving anterior cervical disectomy and spine fusion underwent treatment with cages containing exclusively autologous osteophyte collected from both anterior and posterior vertebral edges adjacent to the intervertebral space.There were 52 males and 29 females,aged from 55 to 78 years,average 64.1 years in this study.46 patients received one-level fusion,and 35 patients received two-level fusion respectively.Patients were followed up at 3 months,6 months and 1 year after operation.The fusion was evaluated by X-ray film and reconstructive CT.Results The total fusion rate after 3 months of operation was 76.5％ (62/81),the one-level and two-level fusion rate were 78.3％ (36/46) and 74.3％ (26/35),respectively.The total fusion rate after 6 months of operation was 93.8％ (76/81),the one-level and two-level fusion rate were 95.7％ (44/46) and 91.4％ (32/35),respectively.The total fusion rate was 100％ (81/81) after 1 year of operation.No statistically significant difference in fusion rate was found between the two groups.Conclusions The method of using cage filled with osteophyte can acquire ideal fusion rate in one-and two-level anterior cervical disectomy,fusion and plate fixation.

Objective To explore the feasibility and clinical efficacy of modified transforaminal lumbar interbody fusion for the treatment of lumbar spinal stenosis with lumbar instability in the elderly.Methods Retrospective study was done on 45 elderly patients diagnosed as lumbar spinal stenosis with lumbar instability treated by modified transforaminal lumbar interbody fusion from June 2011 to December 2012.There were 25 males and 20 females aged from 65 to 78 years [mean (70.64.0) years].The operation time,blood loss,and complications were recorded and analyzed.The visual analog scale (VAS) score,and Japanese Orthopaedic Association (JOA) score were used to assess clinical outcomes before and 3 months after treatment and at the last follow-up.According to the criteria of Brantigan-Steffe,intervertebral fusion was evaluated.Results The operation of 45 patients was successful,and there were no severe complication.The average operative time was (126 23) min,(range,100～ 185 min),and the average amount of blood loss was (272±89) ml (range,180-550 ml).There was no injury of nerve root,dural tear,or deep infection.All patients were followed up for 12 months to 30 months with an average of (20.6±5.8) months.The VAS score of low back pain was decreased from (4.8 ± 1.7) before operation to (1.6 ± 0.5) at 3 months after operation and (1.3±0.3) at last follow-up.The VAS score of leg pain was decreased from (6.7±1.6) before operation to (1.2±0.5) at 3 months after operation and (0.6±0.3) at last follow-up.The JOA score was increased from (13.2±4.9) before operation to (23.8±4.0) at 3 months after operation and (24.1 4.2) at last follow-up.There were significant differences in the VAS score and JOA score between pre-and post-operation (F=68.35,98.58,89.73,all P＜0.05),but no significant difference between 3 months after operation and final follow-up (all P ＞ 0.05).We observed no pedicle screw loosening,breaking,orany pullingout of intervertebral fusion cage.All patients showed evidence of fusion in each operated segment according to the criteria of BrantiganSteffe.Conclusions Modified transforaminal lumbar interbody fusion has the advantages including less invasion,sufficient decompression,and less interference to neural structures,and it may provide an ideal surgical method for lumbar spinal stenosis with lumbar instability in the elderly.

Objective To investigate the expression of E-cadherin(E-cad)and the relationship with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis of gastric cancer. Methods 80 cases architecture of gastric cancer and normal tissue were collected.The expression level of E-cad in 80 cases of gastric carcinomas and their metastatic lymph node tissues were examined by immunohistochemical assays.Results The expression rate of E-cad in 80 cases of gastric carcinomas Was 55.00%.The expression level of E-cad was positively correlated with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis(P＜0.05),but Was not correlated to patients sex,age and tumor size.The expression rates of E-cad in metastatic gastric carcinoma of primary lesions and lymph nodes metastasis were 35.48%and 32.26%. respectively. Furthermore, E-cad expression in metastatic gastric carcinoma was significandy correlated with primary lesions and lymph node memstasis(r=0.4978,P＜0.05).Conclusion The expression level of E-cad in gastric carcinoma Was closely correlated with the degree of tumor differentiation,infiltration and transferring.

OBJECTIVETo study the prevalence of cerebral palsy (here in after referred to CP) in children aged 1 - 6 in Guangxi, China, and its epidemiologic characteristics and relevant risk factors.

METHODSInvestigations on the prevalence and etiology of CP in children at ages of 1 - 6 were conducted in Nanning, Hengxian and Qinzhou of Guangxi from June to December in 1998, with a cluster sampling.

RESULTSTotally, 150 806 children aged 1 - 6 were investigated in Nanning, Hengxian and Qinzhou of Guangxi, with 89 418 boys and 61 388 girls. Among them, 193 children were diagnosed as CP, with a prevalence rate of 1.28 per thousand, higher in boys (136 cases, 1.52 per thousand ) than in girls (57 cases, 0.93 per thousand ), with statistical significance (chi(2) = 9.536 7, P = 0.02). Logistic regression analysis showed that risk factors for CP were children who could not cry after birth (neonatal asphyxia), Apgar score less than eight, delivery at lower level of maternity hospital, number of mother's gravidity, no prenatal checks for mothers, and taking antipyretics and preserved food with salt during pregnancy.

CONCLUSIONSPrevalence of CP in children of Guangxi was at a lower level in comparison with that in other areas at home and abroad, which, maybe, was related with the lower neonatal survival and higher infant mortality.
