Objective To investigate the effects of pretreatment with different concentrations of sufentanil of ketamine on the differentiation of human helper T cells in vitro. Methods Twenty-two healthy volunteers (11 males, 11 females) aged 20-45 yrs were enrolled in this study. In each volunteer 20 ml of blood was taken from peripheral vein and divided into 7 groups: control group (0.9% NaCl), 3 sufentanil groups (0.05, 0.5, 5.0 ng?ml-1) and 3 ketamine groups (100, 500, 2 500 ng?ml-1) .Whole blood and mononuclear cells from peripheral blood (PBMCs) were incubated in the presence of 0.9% NaCl or different concentrations of sufentanil or ketamine for 24 h. Then the stimulants-phorbolmyristate + lonomycin + glgistap (inhibitor of intracellular protein transport) were added to whole blood and phytohemagglutinin (PHA) was add to PBMCs. The whole blood was incubated for another 4h and PBMCs were incubated for another 48 h. Then the T-lymphocytes were collected for determination of intracellular level of IFN-?(as a marker of Th1 cells) and IL-4 (as a marker of Th2 cells) in the whole blood using three-color flow cytometry and the expression of CCR5 + (as a marker of Th1 cells) and CCR3 + (as a marker of Th2 cells) in PBMCs. The Th1/Th2 ratio was calculated. Results In sufentanil 0.5 and 5.0 ng?ml-1 groups the percentage of Th2 cells was significantly increased while the percentage of Th1 cells and Th1/Th2 ratio were significantly decreased. In ketamine 500 and 2 500 ng?ml-1 groups the percentage of both Th1 and Th2 cells were significantly decreased and the Th1/Th2 ratio was significantly increased. Conclusion Sufentanil can encourage helper cells to differentiate into Th2 cells while ketamine inhibit the helper cells to differentiate into Th1 and Th2 cells, especially the Th2 cells in a dose-dependent manner.

Thromboembolic diseases are major health problems worldwide,and remain the leading cause of mortality and disabil-ity at present.Bleeding is the most important complication of an-tithrombotic therapy for thromboembolism,therefore research and development of new antithrombotic drugs with lowered bleeding risk is a significant medical need.The data that elevated plasma levels of FXI are associated with thromboembolic diseases,se-vere FXI deficiency reduced incidence of DVT and ischemic stroke,and FXI deficiency or inhibition in animals shows protec-tive effects against thrombus formation supporting FXI as a novel antithrombotic target with lowered bleeding risk.This paper re-views the progress on FXI as a novel antithrombotic target and the inhibitors target FXI.

Currently,the incidence of breast cancer ranks first at home and abroad of female cancer and the age of onset tends to be younger.Due to the local changes of the tumor residual cavity after the breast conserving surgery,we can't accurately delineate the irradiation range using traditional breast conserving surgery combined with external irradiation of whole breast and tumor bed plus the amount,and the course of treatment is longer.Intra-operative radiation therapy (IORT) can avoid the impact of respiratory motion and postural changes.Meanwhile,it can immediately irradiate the tumor bed intraoperative accurately.For patients,IORT can shorten the cycle of radiotherapy and reduce irradiation on the skin and subcutaneous tissue.So IORT is convenient,easy to be accepted,and it has relatively few complications,good cosmetic results and so on.In recent years,more and more Cancer Center choose breast conserving surgery combined with IORT for the treatment of early stage breast cancer and do researches to the indications,methods,dosage,efficacy and prognosis of IORT.

Objective To investigate the diagnostic value of blood homocysteine,ankle -brachial index and brachial -ankle pulse wave velocity in elderly patients with coronary heart disease (CHD).Methods 97 patients with routine coronary angiography were classified into CHD group (65 cases)and non -CHD group (32 cases) according to the results of coronary angiography.There were 24 cases with single -vessel disease in 65 CHD cases, 21 cases with double -vessel disease and 20 patients with multivessel disease of CHD.Basic clinical parameters,age, gender,TC,TG,LDL -C,HDL -C,etc and blood HCY,ABI,baPWV levels were compared among groups.Results The age of double -vessel disease group,multivessel disease group was significantly higher than that in single -vessel disease group(t =3.721,3.927,all P <0.05).HCY,ABI,baPWV in CHD group were (18.29 ±2.73)μmol/L, (0.97 ±0.16),(16.38 ±1.27)m/s,which had statistically significant differences compared with non -CHD group (HCY:t =5.701,P <0.01;ABI:t =6.138,P <0.01;baPWV:t =15.132,P <0.01 ).There were no significant differences between single -vessel disease group and non -CHD group on the ABI(all P >0.05),and the ABI of multi -vessel disease,double vessel disease group were significantly lower than that of non -CHD group (all P <0.01).HCY,baPWV of CHD group were significantly higher than non -CHD group(all P <0.01 ),double vessel disease,HCY multivessel disease group,ABI,baPWV average water with single -vessel disease group were signifi-cantly different(all P <0.01 ).With the increase of coronary lesions involved,the blood HCY,baPWV showed an increasing trend and ABI showed an decreasing trend.Conclusion Combined detection of HCY,baPWV and ABI has great value in early detection and early intervention of CHD in the elderly.

Objective To discuss the clinical characteristics for central compartment lymph node metastasis in stage cNO papillary thyroid microcarcinoma and significance and feasibility of preventive dissection,aimed to provide reference for clinical treatment.Methods Reviewed the clinical data of 277 patients with stage cNO papillary thyroid microcarcinoma from Jul.2011 to Dec.2015 underwent surgery in the Department of General Surgery of Lianyungang East Hospital.Evaluated the necessity of prophylactic central lymph node dissection.Adopted chi square test and Logistic regression to analyze its relationship with patients' gender,age,tumor number,tumor size,enveloped infiltration,single and bilateral tumor.All 277 patients underwent primary radical resection with ipsilateral central lymph node dissection.The specimen of resection was analyzed by routine pathology.Results The positive rate of thyroid papillary microcarcinoma lymph node metastasis was 36.8 ％ (102/277).The elements of male patients (P =0.023),age ＜ 45 years (P ＜ 0.001) and tumor diameter ＞ 0.5 cm (P =0.019)had high positive rate.The multivariable analysis showed that male patients (OR =2.63,P ＜ 0.001),age ＜ 45 years (OR =2.25,P =0.016),tumor diameter ＞ 0.5 c m (OR =2.13,P =O.009) were independent risk factors for CLN metastasis.Forty-three (15.5％) cases had transient parathyroid function.No Permanent recurrent nerve paralysis and hyperparathyroidism occurred in this group.Conclusions Prophylactic central lymph node dissection is helpful for accurate staging of tumor classification and risk assessment,has important significance,on the follow-up of patients after treatment of choice.For male patients,age ＜ 45,tumor diameter ＞ 0.5 cm,enveloped infiltration,the central compartment lymph node dissection may be necessary.

Background Interleukin-6 (IL-6) is a pleiotropic cytokine involving in inflammation and wound healing.Previous report found that IL-6 increases phosphorylated STAT3 (p-STAT3) level and promotes corneal epithelial wound healing by stimulating migration.However,the essential role of IL-6 in corneal epithelial wound healing and the expression changes in diabetic mellitus remains unknown.Objective This study was to explore the roles of IL-6 in corneal epithelial proliferation and wound healing in both normal and diabetic mice.Methods Fifty-two normal C57BL/6 mice were randomized into normal control group (32 mice) and diabetic group (20 mice).Type 1 diabetic mellitus was induced by intraperitoneal injections of 50 mg/kg streptozotocin once per day for consecutive 5 days in the mice of the diabetic group.Whole corneal epithelium was scraped in all mice,and the corneal epithelial defect area was examined by fluorescein staining in 24,48 and 72 hours after corneal epithelium removal.Recombinant mouse IL-6 or anti-IL-6 blocking antibody of 5 μl were subconjunctivally injected according to the grouping and contrasted with PBS injection group or isotype control antibody group,respectively.TKE2 cells,a mouse corneal epithelial stem/progenitor cell line,were trypsinized and incubated in the KSFM with different concentrations of IL-6 or without IL-6,and colony formation efficency (CFE) was examined by crystal violet staining.The expressions of △NP63 and Ki67,specific makers of stem cells,were detected by immunofluorescine technology.The expressions of △NP63,Ki67 and p-STAT3 proteins were assayed in the cells by Western blot,respectively.The expression of IL-6 mRNA and protein in the regenerated corneal epithelium was detected by real time quantitative PCR and ELISA.The use and care of the mice complied with the Statement of Association for Research in Vision and Ophthalmology.Results The percentage of residual corneal epithelium defect area with initial detect area was gradually shrinked over time after PBS and IL-6 injection in both normal control mice and diabetic mice,and the percentage of residual corneal epithelium defect area was significantly reduced in the IL-6 injected group compared with the PBS injected group (normal control group:Fgroup =19.982,P ＜ 0.01;Ftime =589.350,P ＜ 0.01;Diabetic group:Fgroup =25.411,P＜0.01;Ftime =334.807,P＜0.01).The CFE was (13.23± 1.12)％,(15.87± 1.30)％,(21.69±1.62)％,(25.33±1.28)％ and (18.67±1.54)％ in the blank control group and 10,20,50,100 ng/ml IL-6-treated groups,respectively,showing a gradual increase of CFE dependent upon IL-6 concetrations (F =35.547,P＜0.01).The expressions of △NP63,Ki67,p-STAT3 proteins in the cells were gradually increased over time after 50 ng/ml IL-6 treated for 5,10,15,30 and 60 minutes,and the relative expression level of the cytokines was significnatly higher in the IL-6 cultured groups than that without IL-6 culture group (all at P＜0.05).The relative expression of IL-6 mRNA in the regenerated corneal epithelilum was 0.45±0.21 and 1.00±0.16 in the diabetic group and normal control group,respectively,and compared with the normal control group,the expression of IL-6 mRNA reduced by 56％ (t=3.42,P=0.03).The content of IL-6 protein in regenerated corneal epithelium of the diabetic group was (257±12) ng/μl,which was significantly lower than (323 ± 17) ng/μl of the normal control group (t =5.60,P＜0.01).Conclusions IL-6 promotes the proliferation and regeneration of corneal limbal stem cells to repair defected corneal epithelium by activating STAT3 signaling pathway in both normal and diabetic mice,while the blocking of endogenous IL-6 impairs the corneal epithelial cell activation and wound healing.
