Objective To explore the application of different approaches in single lateral endoscopic thyroidectomy.Methods Ninety one patients with single lateral thyroid nodule who underwent endoscopic thyroidectomy were divided randomly into bilateral axillo-breast approach group (n =45) and transaxillary approach group (n =46).The clinical data and cosmetic outcomes were compared.Results Procedures were successfully performed in 86 patients with no conversion to open surgery,5 patients in transaxillary group were excluded because of the malignant frozen pathology.The total operation time of transaxillary approach group was (61.6 ± 4.9) min,significantly shorter than that of the bilateral axillo-breast approach approach (90.0 ± 6.5) min,P ＜ 0.05.There was no significant difference in time of subcutaneous tunnel construction,muscles disposal,lateral dissection,lower pole resection,parathyroid identification,thyroid lobe resection and bleeding volume between two groups (P ＞ 0.05),while the time of work space creation,upper pole resection in transaxillary approach was significantly shorter than that in the bilateral axillo-breast approach (P ＜ 0.05).All patients of both groups were satisfied with cosmetic results.Conclusions The operation time in transaxillary approach group was shorter than that in bilateral axillo-breast approach group for the single lateral thyroid nodule,but the operation was more difficuh.

ObjectiveTo evaluate treatment of type 2 diabetes mellitus (T2DM) by laparoscopic Roux-en-Y gastric bypass (LRYGB) using different amastomoses. MethodsTwenty one T2DM patients were divided into two groups:transoral EEA (OrVil) and Endo-GIA according to ways of gastrointestinal anatomosis andunderwentLRYGB. Clinicaldataincluding outcomeof operation, complications,preoperative and postoperative oral glucose tolerance test (OGTT),Homa-IR,Homa-β,blood lipid and nutrition status were analyzed.ResultsLRYGB procedures were successfully performed in all the 21 patients with no conversion to open surgery.The difference of intraoperative blood loss,postoperative recovery time between two groups was not significant.The mean operation time in OrVil group ( 126 ± 29 )mins was shorter than that in Endo-GIA group ( 156 ± 28 ) mins ( P ＜ 0.05 ),but at the same time,the mean expenditure was higher. Evaluated on three months after operation,the T2DM cure rate was 78％,and effective rate was 100％ in OrVil goup and those were 83％,100％ respectively in Endo-GIA group.No postoperative malnutrition, anemia or severe complication occurred.ConclusionsThe efficiency of laparoscopic Roux-en-Y gastric bypass using different amastomoses was same in the treatment of type 2 diabetes mellitus.The operation time was shorter in OrVil group but the expenditure was higher.

Objective To investigate the technical difficulties and the avoidance of complications in delayed laparoscopic cholecystectomy (LC) for acute cholecystitis (AC).MethodsThe results of LC carried out on 133 consecutive patients with AC between February 2004 and August 2008 were retrospectively studied.The outcomes were compared between patients who received LC for AC within 72 hours (the early group) and those after 72 hours (the delayed group).There were 34 patients in the early group and 99 in the delayed group.During LC,Calot's triangle was carefully dissected,and the relationship of the cystic duct to the CBD and common hepatic duct was clearly identified.Retrograde cholecystectomy in 2 patients was used when the Calot's triangle was poorly identified.Laparoscopic subtotal cholecystectomy was carried out in 4 patients whose inflammation or fibrosis precluded dissection of the Calot's triangle.ResultsThere was no conversion to open cholecystectomy,biliary tract injury,biliary leak,or any other intraoperative or postoperative complications.There was no 30day readmission in the 2 groups.Patients who received delayed LC had a significantly longer operation time [(44.1±5.32) vs (66.4±3.05)rnin,P＜0.01].There was no significant difference in wound infection rates in the 2 groups (1/34 2.94 ％ vs 2/99 2.02 ％,P＞0.05).ConclusionsDelayed LC was as feasible and safe as early LC in the treatment of AC.Delayed LC was technically more demanding than early LC.

Objective:To investigate the predictive value of preoperative peripheral blood lymphocyte to monocyte ratio (LMR) for lymph node metastasis in gastric cancer.Methods:Data of 177 gastric cancer patients who underwent surgical treatment in Beijing Shijitan Hospital from Jan 2014 to May 2017 were retrospectively analyzed. According to the ROC curve, the optimal critical value is determined to be 3.79. By this value, patients were divided into high LMR group (LMR≥3.79) and low LMR group (LMR<3.79). Patients′ clinicopathological characteristics were collected to analyze the relationship between LMR and lymph node metastasis and lymph node N staging.Results:A comparison of LMR and N1 and N2 stage between the two groups showed no significant difference, but both N1 and N2 had statistical defference with N3 ( P<0.05), suggesting a positive correlation between low LMR and high N stage. Logistic regression analysis proves that low LMR is significantly correlated with metastatic lymph node when the number was more than 6. Conclusion:Low LMR is positively correlated with lymph node metastasis in gastric cancer patients.

Objective:To evaluate the application of Moorehead-Ardelt Ⅱ questionnaire (MA Ⅱ) in assessment of the quality of life (QOL) among obese patients after bariatric surgery.Methods:One hundred and five patients with obesity were enrolled, the weight, body mass index (BMI), comorbidities and MA Ⅱ scores before and after operation were counted. The difference between the QOL of pre- and post-operation was analyzed.Results:All the patients completed the questionnaire. The Cronbach α coefficient of the questionnaire was higher than 0.7. The post-operational scores of 6 items were significantly higher than that of pre-operation. ( P<0.001). The proportion of "poor" and "very poor" QOL in the pre-operational patients was 43.8%, compared with 0 in the post-operative patients;the proportion of "good" and "very good" QOL in the pre-operatve patients was 4.7%, compared to 86.7% in the post-operative patients ( χ2=146.863, P<0.001). Conclusions:MA Ⅱ questionnaire is a professional, easy oprated tool for assessment of QOL associated with obesity.

Objective To explore the morbidity of surgery in connection with laparoscopic sleeve gastrectomy (LSG) and its effect on obese T2DM.Methods 106 obese T2DM patientes undergoing LSG were divided into 2 groups in group 125 patients did not have oversewing the staple line and group 281 patients had the staple line oversewn in order to reduce bleeding.Results The differences in intraoperative blood loss (35 ± 15) ml vs.(28 ± 18) ml,postoperative recovery time (2.4 ± 0.9) d vs.(2.3 ± 0.9) d,time to taking liquid food (4.7 ± 1.0) d vs.(4.6 ± 1.0) d between two groups were not significant.There were no significant difference of complication between 2 groups (x2 =3.271,P =0.071).Comparing before surgery to 6 month after surgery,the BMI in group 1,was from (39 ± 5) to (29 ±4) kg/m2;in group 2,from (40 ±6) to (31 ±5) kg/m2,FPG in group 1,from (8.4 ± 1.4) to (6.4 ±1.2) mmol/L;in group 2,from (8.2 ± 2.0) to (6.8 ± 1.5) mmol/L,2 hour post-meal blood sugar [group 1,(13.2±4.1) to (9.6±3.2) mmol/L;group 2,(12.2±3.2) to (10.6±2.8) mmol/L] and HbAlc (group 1,7.2％ ±1.2％ to5.5％ ±1.1％;group 2,7.1％ ±1.1％ to 5.9％ ±1.2％) decreased significantly in both groups (P ＜ 0.01).There was 72 (68％) remission cases of T2DM in 106 patients,there were no significant differences of T2DM remission and BMI between 2 groups at 6 months after surgery (P =0.617).Conclusions LSG leads to significant weight loss and T2DM control.

BACKGROUNDLaparoscopic cholecystectomy has been widely used in clinical practice during the recent decades; however, the effects of pneumoperitoneum and the surgery on the coagulation system are largely unknown. This clinical study aimed to observe any possible effects of pneumoperitoneum and the surgery on the coagulation system of patients.

METHODSThis was a prospective observational study. The inclusion criteria included (1) patients with chronic cholecystitis and/or cholecystic polyps and (2) patients in the relief stage of acute cholecystitis. The exclusion criteria included (1) patients in the episodic stage of acute cholecystitis and those complicated with cholangiolithiasis; (2) patients with concomitant hematologic diseases, damages to the liver function, malignant tumors or immune system diseases, or patients complicated with thrombotic or hemorrhagic disorders; and (3) patients who had taken anticoagulant medication within a week before surgery. Fifty patients who were hospitalized into our department for elective laparoscopic cholecystectomy between November 2011 and February 2013 were eligible and enrolled into this study. Of the 50 patients, 22 were male and 28 female. The age of the patients ranged from 29 to 78 (mean 56.7±11.5) years. The surgery for each of the 50 patients was performed with the same equipment and conditions. The surgeries for all the patients were performed under general anesthesia with the patients in a 30-degree head-up tilted posture, and the pressure of pneumoperitoneum was maintained at 13 mmHg. Venous blood specimens were taken from each patient before and at the end of pneumoperitoneum (i.e., 0 hour after surgery) and at 8 hours after surgery for determination of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), thrombin time (TT), and D-dimer (DD). The results of the determinations of these parameters were compared.

RESULTS(1) All the patients recovered well without any complications. (2) The pre-pneumoperitoneum values of the parameters of coagulation had normalized. (3) The PT values slightly increased (P > 0.05) at the end of pneumoperitoneum (i.e., 0 hour after surgery) and decreased by 0.5 seconds at 8 hours after surgery as compared to the pre-pneumoperitoneum values (P < 0.05). (4) APTT at 0 and 8 hours decreased by 1.4 seconds (P > 0.05) and 3.7 seconds (P < 0.05) respectively as compared to pre-pneumoperitoneum values, while the difference between the APTT values at 0 and 8 hours after surgery was not statistically significant (P > 0.05). (5) FIB determined at 0 hour post-operation increased by 0.1 g/L as compared to pre-pneumoperitoneum values (P > 0.05); however, the FIB values at 8 hours after operation increased by 1.2 g/L as compared to the pre-pneumoperitoneum values (P < 0.05), and increased by 1.1 g/L as compared to 0 hour post-operation (P < 0.05). (6) The TT values obtained at 0 and 8 hours post-operation were not significantly different as compared to the pre-pneumoperitoneum values (P > 0.05). (7) The DD values gradually increased after operation; as compared to pre-pneumoperitoneum values, DD at 0 and 8 hours after operation increased by 210.8 ng/ml and 525.9 ng/ml respectively (P < 0.05) and DD at 8 hours after operation increased by 315.1 ng/ml as compared to 0 hour post-operation (P < 0.05).

CONCLUSIONSThe pneumoperitoneum for laparoscopic cholecycstectomy may lead to postoperative hypercoagulation in the patients, and thereby may increase the risks for development of postoperative thrombosis; Patients may have risks for occurrence of thrombosis within 8 hours after the operation, to which attention should be paid in favor of preventing thrombosis.

OBJECTIVE: The aim of this study is to explore the potential modulatory role of quercetin against Endotoxin or lipopolysaccharide (LPS) induced septic cardiac dysfunction. METHODS: Specific pathogen-free chicken embryos ( n = 120) were allocated untreated control, phosphate buffer solution (PBS) vehicle, PBS with ethanol vehicle, LPS (500 ng/egg), LPS with quercetin treatment (10, 20, or 40 nmol/egg, respectively), Quercetin groups (10, 20, or 40 nmol/egg). Fifteen-day-old embryonated eggs were inoculated with abovementioned solutions via the allantoic cavity. At embryonic day 19, the hearts of the embryos were collected for histopathological examination, RNA extraction, real-time polymerase chain reaction, immunohistochemical investigations, and Western blotting. RESULTS: They demonstrated that the heart presented inflammatory responses after LPS induction. The LPS-induced higher mRNA expressions of inflammation-related factors (TLR4, TNFα, MYD88, NF-κB1, IFNγ, IL-1β, IL-8, IL-6, IL-10, p38, MMP3, and MMP9) were blocked by quercetin with three dosages. Quercetin significantly decreased immunopositivity to TLR4 and MMP9 in the treatment group when compared with the LPS group. Quercetin significantly decreased protein expressions of TLR4, IFNγ, MMP3, and MMP9 when compared with the LPS group. Quercetin treatment prevented LPS-induced increase in the mRNA expression of Claudin 1 and ZO-1, and significantly decreased protein expression of claudin 1 when compared with the LPS group. Quercetin significantly downregulated autophagy-related gene expressions (PPARα, SGLT1, APOA4, AMPKα1, AMPKα2, ATG5, ATG7, Beclin-1, and LC3B) and programmed cell death (Fas, Bcl-2, CASP1, CASP12, CASP3, and RIPK1) after LPS induction. Quercetin significantly decreased immunopositivity to APOA4, AMPKα2, and LC3-II/LC3-I in the treatment group when compared with the LPS group. Quercetin significantly decreased protein expressions of AMPKα1, LC3-I, and LC3-II. Quercetin significantly decreased the protein expression to CASP1 and CASP3 by immunohistochemical investigation or Western blotting in treatment group when compared with LPS group. CONCLUSION Quercetin alleviates cardiac inflammation induced by LPS through modulating autophagy, programmed cell death, and myocardiocytes permeability.
