Surgery for Obesity and Related Diseases | Year: 2015

Background Laparoscopic adjustable gastric banding (LAGB), as one major bariatric surgery for treatment of obesity, results in ineffective long-term weight loss and a high reoperation rate. The objective of this study was to evaluate the long-term effects of LAGB on the weight loss outcomes and reoperation rates of obese patients with different body mass index (BMI) levels in China. Methods A retrospective study was performed to review the follow-up data of obese patients who underwent LAGB at Shanghai Changhai Hospital between November 2003 and May 2013. The main outcomes included weight loss, percentage excess weight loss (%EWL), reoperation rate, and reasons for reoperation. Results A total of 254 LAGB procedures were performed in our hospital. By the end of May 2013, 145 Chinese patients (57.8%) were followed up, 99 patients with BMI≥35 kg/m2 (high BMI group) and 46 patients with BMI<35 kg/m2 (low BMI group). In the high BMI group, the mean %EWL was>25% within 5 years postoperatively, but it decreased to less than 25% after 5 years. However, in the low BMI group, the mean %EWL at each time point was over 50%. The reoperation rate was 33.1%; it was 17.4% in the low BMI group and 34.3% in the high BMI group. Conclusion LAGB is more effective with a lower reoperation rate for obese patients with a BMI<35 kg/m2 compared to BMI≥35 kg/m2 in our population. © 2015 American Society for Bariatric Surgery.

Purpose: Soils have a wide range of pore size distribution (PSD) from nanometer to micrometer scale. The detailed characterization of soil pore structure in a wide pore size range is important for understanding the soil processes. In this study, three different techniques are used to quantitatively describe the soil pore characteristics in a wide pore size range and to evaluate whether different pedogenic processes affect porosity and PSD of the soils. Materials and methods: The four different types of soils: black soil (BS, Udic Agriboroll), Shajiang black soil (SBS, Aquic Pelludert), paddy soil (PS, Aeric Endoaqualf), and latosolic red soil (LRS, Typic Kandiudults) were selected to represent the most important soil types in China. A combination technique of nitrogen adsorption isotherm (NAI), mercury intrusion porosimetry (MIP), and synchrotron-radiation-based X-ray computed microtomography (SR-mCT) was used to describe the pore structure characteristics including the porosity, PSD, and pore geometry in the soils. Results and discussion: The NAI method revealed larger differences in the Brunauer-Emmett-Teller (BET) surface area and 0.002–0.15 μm pore volume for the studied soils. The latosolic red soil (LRS) has the largest volume of 0.002–0.15 μm pore, while BS has the smallest. The PSD determined by MIP exhibited that BS and paddy soil (PS) had multimodal peaks, indicating the existence of a more heterogeneous pore system. The PSD from LRS and SBS exhibited a single, sharply defined peak at a pore diameter from 0.02 to 0.04 and 0.01 to 0.06 μm, respectively. The volume of the >3.7 μm pores determined by the SR-mCT method was in the order of BS (18.2 %) > PS (10.6 %) > LRS (7.2 %) > SBS (5.4 %). The pore shape measured by SR-mCT has an obvious difference in pore system for different soils. Regular pores were more frequent in BS than in SBS, PS, and LRS. Conversely, lower percentage of irregular pores was found in the BS. Conclusions: The combination of NAI, MIP, and SR-mCT techniques can quantify the porosity and PSD of soils over a wide range of pores. For the overlapping pore region, the pore volume determined by the MIP and SR-mCT agreed well. Our results indicated that pedogenic processes can greatly influence the soil pore structure both in terms of PSD and pore shape. © 2014, Springer-Verlag Berlin Heidelberg. Source

Objective: To evaluate the medium to long-term curative effects of surgical long segmental fixation and fusion in degenerative scoliosis (DS). Patients and methods: From January 2001 to December 2011, 56 DS patients underwent long segmental fixation and fusion. Clinical data, including visual analogue scale (VAS) scores, Oswestry disability index (ODI), lumbar lordosis angles, coronary Cobb angles and postoperative complications were followed up for 2 to 12 years postoperatively. Results: VAS and ODI scores were significantly improved 1 year postoperatively compared to the preoperative values (P = 0.000). Coronary Cobb angles were significantly improved three months postoperatively (P = 0.001) but ≥ 1 year after surgery there was no further significant improvement compared to the preoperative values (P = 0.585). The lumbar lordosis angle was not significantly changed postoperatively (P > 0.05). Conclusions: Favorable medium to long-term curative effects can be achieved by long segmental fixation and fusion. Ideally, the fixation and fusion segments should be longer than the segments affected by scoliosis. The restoration of the lumbar lordosis angle is the key to rebuilding sagittal balance, which is closely correlated with a patient’s clinical symptoms and quality of life. © 2015, E-Century Publishing Corporation.

Objective To observe the clinical effect of small dose of colchicine combined with glucocorticoid for acute gouty arthritis. Methods Ninety-two patients with acute gouty arthritis were equally and randomly divided into small doses of colchicine combined with dexamethasone treatment group (treatment group) and conventional large dose colchicine treatment group (control group) between January 2009 and December 2013. The articular lesion scoring and clinical efficacy evaluation were performed at 3, 6, 12, 24, 48, and 72h after treatment. Erythrocyte sedimentation rate (ESR), white blood cells, hepatorenal function and glomerular filtration rate (GFR) were determined before and 72h after treatment respectively. The gastrointestinal adverse events and recurrence rate were observed within one month after treatment. Results The articular lesion scores were significantly decreased at 6, 12, 48, and 72h after treatment in treatment group compared with control group (P<0.05 or P<0.01). Compared with that of pre-treatment, ESR and white blood cell count were decreased significantly 72h after treatment (P<0.05), but there was no statistical difference between the two groups (P>0.05). Serum uric acid, glutamic-pyruvic transaminase in serum (SGPT), and GFR did not show any change before and 72h after the treatment, and there was also no significant difference between groups (P>0.05). The incidence of gastrointestinal adverse events were obviously higher in control group (76.1%) compared with that of the treatment group (P<0.05), and the differences was statistically significant. There was no statistical difference in recurrence rate between the control group and treatment group after a follow-up of one month. Conclusions Compared with conventional large dose colchicine, small dose of colchicine combined with dexamethasone can more rapidly and effectively control acute gouty arthritis, with good tolerability and safety, thus being worthy of popularization clinically. © 2015, People’s Military Medical Press.

Objective: To evaluate the efficacies of treating osteonecrosis of the femoral head (ONFH) with percutaneous retaining catheterization. Methods: A total of 85 patients (106 hips) of ONFH underwent percutaneous retaining catheterization with self-made instrument. There were stage I (n=32, 40 hips), stage II (n=41, 50 hips), stage III (n=7, 9 hips) and stage IV (n=5, 7 hips) by Ficat and Arlet classification. The selection criteria include bone marrow edema (BME) of the femoral head and neck and joint fluid on magnetic resonance imaging (MRI). The percent method (%) of Orthopedics Branch of Association of Chinese Medical Association was used for evaluating the efficacies of ONFH with retained femoral head. A follow-up period of 2-10 years was conducted with plain radiograph. The standard was as follows: > 90, excellent; 75-89, good; 60-74, passable; < 60, bad. The combination of excellent and good denoted obvious effect rate; passable for valid rate; bad for invalid rate. The historical core decompression was used as control group. And χ2 test was used for statistical analysis (P < 0.05). Results: The obvious effect rate was 88% (35/40), 74% (37/50), 22% (2/9), 14% (1/7), the valid rate 7% (3/40), 12% (6/50), 22% (2/9), 14% (1/7) and the invalid rate 5% (2/40), 14% (7/50), 56% (5/9), 72% (5/7) respectively in Ficat I, II, III and IV stage. No statistically significant differences existed between Ficat I and II stage (P > 0.05). But there were statistically significant differences in other groups (P < 0.01). Conclusion: Percutaneous retaining catheterization is efficaciously treating ONFH in Ficat I and II stage and it may also be used for ONFH in Ficat III and IV stage.
