To retrospective analyze the clinical profiles of 80 patients undergoing thoracotomy with protection of intercostal nerve versus traditional method.The doses of narcotics of two groups were (12 ± 5)and (43 ± 11) mg respectively.The postoperative levels of visual analogue score (VAS) and such potential complications as pneumonia,atelectasis and paraesthesia were examined (P ＜ 0.01).Protective technique of intercostal nerve during thoracotomy could effectively relieve postoperative chest pain,reduce the dosage of narcotics and lower the occurrence of lung complications.

Objective To explore the relationship between CA repeats polymorphism in the promoter region of IGF-1 gene and MS in the Han nationality.Methods 1047 subjects were recruited from general population of Dongcheng District in Beijing.MS was diagnosed based on the criteria for MS in 2005 by IDF.Genomic DNA was extracted by standard methods.PCR,Genescan,Genotyper and direct sequencing were conducted to screen CA repeats polymorphism in the promoter region of the human IGF-1 gene.Levels of plasma glucose,lipids,serum insulin and IGF-1 were determined.BMI and ISI were calculated.Results The prevalence of MS in (CA) 19 homozygote was lower than that in (CA) 19 heterozygote (9.1% vs 18.3%,x2 = 8.55,P ＜ 0.01) and without (CA) 19 (9.1% vs 24.0%,x2 = 18.05,P ＜ 0.01).The level of serum IGF-1 had differences among the three groups [ (114.0 ± 52.6) μg/L vs (136.6 ± 80.5) μg/L vs (129.2±49.1) μg/L,F =3.16,P ＜0.05],(CA)19 homozygote had lower serum IGF-1 than (CA)19heterozygote and without (CA) 19.BMI,WC,TG,FIns,2hIns and ISI had difference among the three groups (P ＜0.05).Conclusions (CA)19 repeats polymorphism in the promoter region of IGF-1 gene was significantly associated with MS in Han nationality.

To examine the relationship between genetic variants in the interleukin-6 receptor gene and obesity. The result showed that the carriers of Asp358 homozygotes had higher risk in developing obesity when compared with Ala358 homozygotes (OR = 1.32,95% CI 1.07-1.68, P = 0. 041). Interleukin-6 receptor gene pulymorphism was significantly associated with obesity.

Objective To evaluate the values of continuous subcutaneous insulin/rapid insulin analoguc infusion in desensitization for allergy to recombinant human insulin. Methods Two patients allergic to recombinant human insulin received desensitization therapy by continuous subcutaneous insulin lispro infusion. The diluted insulin lispro solution was pumped with initial basal rate of O. O1 U/h, and the basal rate and insulin lispro concentration increased gradually until the insulin dosage for clinical treatment was reached. After that, continuous subcutaneous insulin lispro infusion was replaced by regimen of insulin lispro subcutaneous injection plus oral hypoglycemic agents. Results Local wheals were not observed in both two patients during continuous subcutaneous insulin lispro infusion or during bolus subcutaneous injection of insulin lispro after desensitization. Conclusion The desensitization therapy by continuous subcutaneous insulin/rapid insulin analogue infusion can be applied for allergy to recombinant human insulin.

Objective To investigate the clinical efficacy of enhanced recovery after surgery (ERAS) in the radical gastrectomy for gastric cancer.Methods The clinical data of 140 patients undergoing radical gastrectomy for gastric cancer at the Affiliated Hospital of Qingdao University from April 2011 to June 2013 were prospectively analyzed.A double-blind,randomized,controlled study was performed in the 140 patients,and all of them were divided into the ERAS group (patients undergoing perioperative management according to enhanced recovery rehabilitation program) and the control group (patients undergoing perioperative management) based on a random numble table.The inflammatory markers,nutritional index and postoperative recovery of patients were observed.Patients of the ERAS group were followed up by telephone interview within the first 24 hours after discharge,and by outpatient examination since the second week after discharge.The follow-up was ended at postoperative day 30.Patients of the control group were reexamined at the third week after discharge.The measurement data with normal distribution was presented as x ± s.The comparison between groups was evaluated with an independent sample t test.The trend analyses for variables were done using repeated measures ANOVA.The count data were analyzed using the chi-square test or Fisher exact probability.Results Eighty patients were screened for eligibility,and were allocated into the ERAS group (40 patients) and the control group (40 patients).The total protein in serum (TP),albumin (Alb),prealbumin,TNF-α,IL-6,c-reactive protein,resting energy expenditure (REE),glycemic index,insulin index and Insulin resistance index in the 2 groups showed a range of variations at postoperative day 1,3,and 5,and these were (61 ±5)g/L,(34 ±3)g/L,(160 ± 18)g/L,(12.3 ±2.3)mmol/L,(101 ±34)ng/L,(43 ± 11)g/L,(1 336 ± 105)kal/d,(7.6 ±0.8)mmol/L,(16.8 ±3.5)mU/L and 5.7 ±1.3 in the ERAS group at postoperative day 1,and (58 ± 4) g/L,(31 ± 4) g/L,(147 ± 18) g/L,(15.3 ± 2.2) mmol/L,(122 ±37)ng/L,(56 ±27) g/L,(1 450 ± 164)kal/d,(9.3 ± 1.4) mmol/L,(30.5 ±6.8) mU/L and 12.5 ±3.2 in the control group,respectively,showing a significant difference between the 2 groups (F =31.63,8.03,67.36,147.04,9.63,6.84,16.10,54.85,104.51,139.47,P ＜0.05).The duration of fever,time to flatus,duration of hospital stay,hospital expenses,numeric rating scale and quality of life (QOL) were (2.9 ±0.9) days,(2.9 ± 0.6) days,(7.6 ± 2.1) days,(28 495 ± 4 722) yuan,1.4 ± 1.0 and 15.4 ± 0.9 in the ERAS group after operation,and (3.8 ±0.6)days,(3.5 ±0.7)days,(8.9 ±2.6)days,(35 318 ±7 610)yuan,2.4 ± 1.1 and 14.4 ± 1.2 in the control group,respectively,with a significant difference between the 2 groups (t =-0.91,-3.66,-2.85,-4.82,-4.20,3.92,P ＜0.05).Two patients were complicated with respiratory diseases,1 patient received reoperation and 1 was readmitted to the hospital at postoperative day 30 in the ERAS group.Three patients had respiratory diseases,1 received reoperation and 2 were readmitted to the hospital at postoperative day 30 in the control group,with no significant difference between the 2 groups (P ＞ 0.05).Conclusions ERAS is safe and feasible for the perioperative treatment of patients with gastric cancer,meanwhile it could reduce the surgical stress,shorten the duration of hospital stay and improve QOL and postoperative complications,ERAS might take effects by reducing insulin resistance and decreasing REE.Registry This study was registered with the Chinese Clinical Trial Registry with the registry number of ChiCTR-TRC-10001611.

Objective To investigate the role of hMSH2 in the pathogenesis of sporadic insulinomas and to determine whether the expression of hMSH2 could be used to differentiate benign sporadic insulinomas from malignant ones. Methods Fifty-five sporadic insulinomas (40 benign and 15 malignant tumors) resected from 50 patients were obtained. Expression of hMSH2 was detected by immunohistochemistry staining. DNA was obtained from micradissected tissue. Loss of heterozygnsity (LOH) of hMSH2 gene was detected by PCR-LOH. 6 microsatellite markers were selected on 3 chromosomes, and microsatellite instability (MSI) status of tumor tissue were detected by PCR. The findings were analyzed in relation to the clinicopathological characteristics. Results Down-regulation of hMSH2 expression was found in 13% of 55 sporadic insulinomas. LOH of the hMSH2 gene was not present in 55 insulinomas. High frequency MSI (MSI-H, MSI occurred in at least 2 out of 6 sites) was present in 36% (20/55) of all the insulinomas. Down-regulation of hMSH2 expression was found in 33% of the 15 malignant tumors, while it was 5% in benign tumors (P < 0. 05). Conclusions Down-regulation of mismatch repair gene hMSH2 may be correlated with the degree of tumor malignancy. The expression of hMSH2 could be used as a potential marker for distinguishing benign insulinoma from malignant ones.
