RESUMO
Obesity is an independent risk factor for many chronic diseases, which seriously affects the quality of life and physical and mental health of patients, and is a serious public health problem facing society. Obesity research is the focus and difficulty of current medical research. At present, laparoscopic sleeve gastrectomy and gastric bypass surgery have become important ways to treat obesity, but the specific mechanism is still unclear. In recent years, research on obesity-related genes has made certain progress. The link between surgery and obesity gene expression is gradually being discovered. Different gene functions such as energy intake and consumption and fat storage by fat cells have also derived different treatment methods. This article will summarize the research on obesity genes.
RESUMO
The number of women of childbearing age having overweight or obesity problems keeps increasing globally. Besides diabetes, hypertension and other chronic conditions, these women may develop metabolic disorders of sex hormones, manifested by irregular menstruation, infertility and obstetric complications. Bariatric surgery offers prominent weight loss and improves obesity-related conditions. Women patients also benefit from elevated chances of pregnancy postoperatively. However, the timing of pregnancy for obese women after surgery has impact on the effects of weight loss surgery, pregnancy complications, delivery outcomes and long-term prospects of mother and child. This article reviews the clinical studies on the timing of pregnancies after bariatric surgery, weight loss results, as well as risks and outcomes.
RESUMO
Osteoporosis is a chronic disease influenced by multiple factors.The fractures associated with osteoporosis are known as osteoporotic fractures.The factors associated with osteoporosis and fracture include oxygen concentration,sunshine,body mass,gender,age,trauma,dietary habits,tobacco and alcohol use,medical history and inheritance.Factors such as oxygen concentration,topography and dietary habits play a more important role in the western plateau areas in China than in the plain areas.The present study reviews the clinical research on the osteoporosis and fracture risks in the plateau areas in China and proposes prevention and treatment measurements for the risk factors to reduce the incidences of osteoporosis and fracture in the plateau areas.
RESUMO
Objective To investigate the condition and causes of needle-stick injuries among health care workers(HCWs), and explore effective strategies for preventing needle-stick injuries.Methods Needle-stick injuries recorded by healthcare-associated infection management department in a hospital between January 2013 and December 2015 were surveyed retrospectively.Results 164 HCWs suffered needle-stick injuries, including 71 (43.29%) doctors, 81 (49.39%) nurses, and 12 (7.32%) other HCWs.The number of injuries in 2013, 2014, and 2015 were 47(28.66%), 54(32.93%),and 63(38.41%)respectively.152(92.68%), 9(5.49%),and 3(1.83%)injuries were caused by contaminated medical instruments, uncertain-contaminated medical instruments, and non-contaminated medical instruments.Among 164 cases of needle-stick injuries, 67(40.85%) occurred in operating rooms, 141 (85.98%) were finger injuries;the main causes of needle stick injuries were carelessness, busy work and nonstandard manipulation(n=115, 70.12%), most doctors suffered needle stick injuries due to the lack of experience (52.11%), most nurses suffered needle stick injuries due to carelessness, busy work and nonstandard manipulation(93.83%).Conclusion Needle stick injuries among HCWs increased year by year, strategies should be implemented to reduce the occurrence of needle injuries, including strengthening occupational protection consciousness among HCWs, strengthening construction of healthcare-associated infection management system, and improving medical environment.
RESUMO
Objective To evaluate the effects of laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy on weight control in morbidly obese patients.Methods 48 patients with morbidly obesity underwent obese surgery (laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy) from Dec.2013 to Dec.2015,and 1-year follow-up study.The general situation of obesity and biochemical indicators were compared and analyzed.Results There were 20 cases in gastric bypass group and 28 cases in sleeve gastrectomy group.The excess weight loss percentage(％EWL)was 73±0.04 in gastric bypass group and 59±0.05 in sleeve gastrectomy group(P=-0.03).There was no statistical difference in weight change between the two groups.Low density lipoprotein cholesterol (LDL) level in gastric bypass group was significantly lower than that in sleeve gastrectomy group at 1 year after surgery (2.42±0.16 vs 3.29±0.20,P=0.006),while folic acid level was significantly higher than that in sleeve gastrectomy group(15.58±1.99 vs 7.59±1.59,P=0.022).Conclusions The one-year follow up shows there is no significant difference in the efficacy of weight control between the two groups.Gastric bypass group may be superior to gastrectomy group in nutrition indexes.However,it is just a short-term postoperative efficacy in morbidly obese patients,long-term weight control effects and obesity related diseases control need to be further explored.
RESUMO
Objective To observe the impact of laparoscopic Roux-en-Y gastric bypass on bowel habits in patients with type 2 diabetes mellitus(T2DM).Methods 70 cases of T2DM undergoing laparoscopic Roux-en-Y gastric bypass were studied.Changes in bowel habits, frequency and odor of flatulence, and social life were estimated at least 6 months after surgery using a self-administered questionnaire.Results 67.1%of the patients had normal bowel habit, 68.6%of patients maintained normal flatus before undergoing surgery, and visual ana-logue scale reveals bowel and flatus habit would cause little trouble on daily life.47.1% of patients maintained their normal bowel habit, and 45.7%of patients had loose stools and diarrhea after surgery.The number of pa-tients with loose stools significantly increased(28/70, 40% after surgery vs 5/70, 7.1% before surgery), with statistical difference( P<0.001) .42.9%patients believed that eating high-fat diet was related with loose stools (P<0.001).Patients with constipation decreased significantly after surgery(5/70, 7.1% vs the preoperative 16/70, 22.9%), with statistical difference(P=0.016).Visual analogue scale showed that 57.1% of patients thought their daily life and social activities were not affected(P=0.05).50%of patients considered an increase flatus, and 55.7%had malodorous flatus, which had statistical significance compared with those before surgery ( P<0.001) .A visual analogue scale showed that 60%of patients thought that this change would not affect their daily life and social activities( P=0.212) .Conclusions After laparoscopic Roux-en-Y gastric bypass surgery, some patients had loose stod, diarrhea, increased flatus and and offensive odor, but after proper treatment these changes do not affect their daily life and social activities.

Objective To investigate the incidence of cholelithiasis after laparoscopic Roux-en-Y gastric bypass(LRYGB) for treatment of type 2 diabetes mellitus with obesity.Methods The clinical data of 89 obese patients with type 2 diabetes mellitus who underwent LRYGB at the Sixth People's Hospital Affiliated to Shanghai Jiaotong University from March 2011 to March 2013 were retrospectively analyzed.Sixty-six patients without postoperative gallstone and sludge were divided into the nornal group and 23 with postoperative gallstone or sludge into the gallstone group.The waistline,hipline,body weight,body mass index (BMI),excess weight loss (EWL),fasting blood glucose,postprandial 2-hour blood glucose,glycosylated hemoglobin (HbAlc),homeostasis model assessment-insulin resistance (HOMA-IR),total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-c),low-density lipoprotein cholesterol (LDL-c),serum total bile acid at postoperative month 6,12,24 were analyzed.The patients were followed up by inpatient,outpatient examination and telephone interview till April 2015.Measurement data with normal distribution were presented as x ± s,comparison between groups and repeated measures data were analyzed using the t test and repeated measures ANOVA,respectively.Count data were analyzed by the chi-square test.Results All the 89 patients underwent successful LRYGB and were fol lowed up for 31 months (range,24-48 months).The EWL,HbAlc and serum total bile acid at postoperativemonth 6,12,24 were 113％±43％,117％±64％,119％±84％ and 6.1％±0.8％,6.2％± 1.1％,6.4％± 1.0％ and (4.6 ± 3.8) μmol/L,(4.5 ± 3.6) μmol/L,(4.6 ± 3.8) μmol/L in the normal group and 157 ％ ± 96％,152％±102％,151％±93％ and 5.9％±0.8％,5.8％±0.6％,5.9％±0.8％ and (23.9 ±9.0) μmol/L,(11.8 ± 7.3) μmol/L,(10.5 ± 9.6) μmol/L in the gallstone group,respectively,showing significant differences in changing trend between the 2 groups (F =6.896,5.226,5.351,P ＜ 0.05).There were significant differences in the EWL at postoperative month 6,12,24 between the 2 groups (t =2.814,2.628,2.099,P ＜ 0.05).There were significant differences in the HbAlc at postoperative month 12 and serum total bile acid at postoperative month 6,24 between the 2 groups (t =2.018,-1.378,-1.990,P ＜ 0.05).Conclusion There is incidence risk of cholelithiasis after LRYGB in obese patients with type 2 diabetes mellitus.The rapid decreasing of weight is associated with cholelithiasis in which patients have higher level of serum bile acid.
RESUMO
Objective To investigate the change in quality of life (QoL) following laparoscopic Roux-en-Y gastric bypass (LRYGB) for T2DM with obesity.Methods A total of 46 overweight T2DM cases (mean baseline BMI (32.7 ± 3.9) kg/m2) undergoing LRYGB were followed by QoL questionnaires (SF-36) before and after 6 and 12 months.Results The preoperative physical QoL scales (physical component summary,PCS) was significantly different from the general population(GP) scales (P ＜ 0.01),and the improvement in QoL was significant at 6 months postoperative and continued to consistently increase up to 12 months (P ＜ 0.01).For mental component summary (MCS),the preoperative scales was not significantly different from the GP scales,however,the 6 and 12 postoperative scales improved significantly (P ＜0.01).As for physical function,role physical,role emotion,the 6 (78 ± 8,76 ± 17,70 ± 23) and 12 months' (85 ± 7,82 ± 18,77 ± 18) postoperative scales were markedly higher than those in the preoperative controls (P ＜ 0.01),and there were no differences between the 12 month's postoperative scales and GP scales.The preoperative bodily pain,general health and social function (66 ± 14,55 ± 12,63 ±15) was different when compared with (76 ± 12,75 ±6,75 ± 13) at 6 months and (82 ±9,79 ±6,94 ±9) at 12 months (P ＜0.01).The preopertive mental health (71 ± 12) was not significantly different from GP scales,nor there were significant difference when compared with (71 ± 10) at 6 months and (73 ±8) at 12 months.Conclusions There were improvements in physical and mental QoL in T2DM patients with obesity after LRYGB.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism (PE) in lower limb bone fracture patients with deep venous thrombosis (DVT).</p><p><b>METHODS</b>From January 2003 to December 2012, 2 248 cases of lower limb and pelvic fractures with DVT were retrospectively analyzed. Before the procedure of IVCF implantation began, January 2003 to December 2007, there were 1 052 cases of acute trauma patients with DVT were classified as the group of early none-IVCF. The IVCF implantation was began since January 2008. From that time to December 2012, 712 cases of bone fractures with DVT received filter implantation, which were classified as IVCF group. The other 484 patients who had not undergone filter deployment were divided as group of late none-IVCF. The baseline conditions of the three groups were significantly different in addition to the ages between group of early none-IVCF and IVCF group. The incidences of PE and mortality of PE in each group were recorded and analyzed by χ(2) test.</p><p><b>RESULTS</b>There were totally 31 cases of symptomatic PE, among which 12 cases died. Totally 712 filters were deployed successfully without any major complications. The incidences of symptomatic PE were 0.14% (1/712), 2.19% (23/1 052) and 1.45% (7/484) in IVCF group, group of early none-IVCF and group of late none-IVCF, respectively. The mortality of PE were 0 (0/712), 0.86% (9/1 052) and 0.62% (3/484) in these groups. The incidence of symptomatic PE in IVCF group was significantly different from that in the group of early and late none-IVCF (χ(2) = 11.762, P = 0.001; χ(2) = 7.395, P = 0.007, respectively). The mortality of IVCF group was also significantly lower compared with the other two groups (χ(2) = 6.122, P = 0.013; χ(2) = 4.424, P = 0.035, respectively).</p><p><b>CONCLUSION</b>IVCF implantation effectively prevents symptomatic and fatal PE of patients of lower limb and pelvic fractures with DVT in the peri-operative period.</p>

Objective To evaluate analgesic effect of bupivacaine infiltration in trocar incision after laparoscopic surgery.Methods 90 patients were randomly divided into 3 groups after laparoscopic cholecystectomy.In group 10.25% bupivacaine 20 ml(50 mg) injection, in group 2 sterile NS 20 ml infiltrated in the muscular fasciae of the trocars, in group 3 patient-controlled intravenous analgesia(PCIA) was used.In 2, 6, 12 and 24 hours after the intervention, the pain intensity was recorded with the use of a Visual Analogue Scale ( VAS), time of flatus passing was recorded as well.Results Patients with bupivacaine or PCIA had statistically significant in pain score compared with patients with NS especially within 12 hours after the surgery (t2h = 8.475; t6h = 5.356; t12h = 3.496, P ＜ 0.05) while the difference was not statistically significant between the 3 groups at 24 hours.The time of passing flatus in group 1 patients with bupivacaine was earlier than with PCIA ( x224h = 5.406, P ＜ 0.05 ) .Conclusions Bupivacaine infiltrated in trocar incision after laparoscopic surgery reduced postoperative pain, and did not disturb peristalsis reflex recovery of the intestines.
RESUMO
Objective To compare the treatment effects of gastric bypass (GBP) and biliopancrtic diversion (BPD) in non-insulin dependent diabetes mellitus rats,and investigate the mechanism.Methods Forty GK rats with diabetes mellitus were randomly allocated into four groups:GBP group; BPD group; food restriction group ( FR group) and control group with 10 rats in each group.Rats in GBP group and BPD group received GBP and BPD procedures respectively.Rats in FR group were fed with basic feed of 15 g and free access to water.There was no food restriction in rats in control group.The operation time,mortality was recorded.The fasting body weight was measured every week.The plasma glucose,insulin-like growth factor-1 (IGF-1),and leptin concentrations,were measured before treatment and 1,2,3,4,8,16 week after treatment.Results The mean operation time was (25 ± 4) min in GBP group and (35 ± 6) min in BPD group; one rat died in GBP group and 3 rats died in BPD group,and the difference between the two groups was statistically significant (P ＜ 0.01 ).The levels of plasma glucose,IGF-1 and leptin were not statistically significant among these groups before treatment.There was no significant difference in plasma glucose and leptin concentrations in the control group.The levels of plasma glucose and leptin in rats in FR group began to decrease 2 weeks later,at the 4th week,the levels of plasma glucose and leptin was significantly lower than that before treatment,and it lasted for the 16 th week,but the level of IGF-1 were significantly different.The levels of plasma glucose and leptin in rats in GBP group and BPD group began to decrease and IGF-1 began to increase 2 weeks after operation,and it lasted for the 16th week,[plasma glucose:(6.8 ± 1.0),(6.3 ± 0.8 ) mmol/L vs.(13.9±2.6),(14.1 ±2.6)mmol/L; leptin:(16.1±3.3),(17.2±3.2)pg/ml vs.(29.4±3.9)pg/ml,(29.4±3.9); IGF-1:(166.1±8.3),(142.2±8.2)ng/L vs.(119.4±8.8),(109.8±7.9)ng/L,P＜0.01],but the levels of plasma glucose and leptin was not statistically different between the two groups.The level of IGF-1 in GBP group was significantly higher than that in BPD group (P ＜ 0.05).Conclusions Both GBP and BPD can effectively control plasma glucose concentration for rats with diabetes.The possible mechanism is related to decreased leptin and increased IGF-1.Group GBP had a better outcome in operation time,mortality and increasing IGF-1 than those in group BPD.
RESUMO
Objective To investigate the strategy to improve successful treatment for severe acute pancreatitis (SAP). Methods The study period was divided into from 1992 to 2000, and from 2001 to 2009.The patients during these two phases were comparable as regard to sex and age. Results The proportion of patients received anti-inflammatory medications from 2001 to 2009 was 88.7% (94/106), medications which can improve the pancreatic microcirculation were used in 93.4% (99/106), early enteral nutrition was used in 58.5% (62/106), medications which can protect intestinal barrier function were used in 98.1% ( 104/106),all these parameters were significantly higher than those (22.4%, 19/85; 43.5%, 37/85; 29.4%, 25/85;17.7%,15/85) from 1992 to 2000. Also from 1992 to 2000, more patients underwent operation such as basin-shaped open drainage, pancreatic necrosis debridement. While more patients underwent operation such as laparoscopic drainage, CT or B-ultrasound guided percutaneous drainage from 2001 to 2009. The proportion of patients underwent surgical treatment decreased from 56.5% (48/85) to 32. 1%(34/106); the survival rate increased from 68.8% to 84.0%. Conclusions The research progress of medications was the foundation to improve successful treatment for SAP. Operation was an important option during SAP therapy. The individualized treatment was beneficial to improve successful treatment for SAP.
RESUMO
Objective To study the safety, surrounding tissue injury and cervical wound appearance of the video-assisted thyroidectomy. Methods 230 patients had video-assisted thyroidectomy (group endoscopy) and 204 had conventional open thyroidectomy (group open). Operative duration, postoperative hospital stay, complications,cervical wound healing and appearance, and recurrence rate were compared. Results Operative duration and postoperative hospital stay were (33±29)min and (2±1)days for group endoscopy and (40±21)min and (5±2)days for group open (P=0.025, P=0.000) respectively. Cosmetic result of wound evaluated by numeric scale was in favor of group endoscopy (P=0.000). There were no significant differences in infection of incisional wound, between two groups (P=0.270). After 6-30 months' follow-up, the recurrence rate showed no difference between two groups(P=0.909). Conclusions Compared with conventional surgery, endoscopic thyroidectomy for thyroid diseases was a practical and safe procedure with excellent cosmetic benefits, short hospital stay and less postoperative complications.
