ObJective To study the effects of flurbiprofen axetil preemptive analgesia on T cell immune functions in postoperative patients with upper abdominal.Methods Seventy-six patients with upper abdominal operation were divided into observation group (40 cases) and control group (36 cases) by random digits table,observation group and control group were given intravenous injection of 100 mg flurbiprofen axetil or 10 ml 0.9％ sodium chloride 10 min before skin incision respectively.Peripheral venous blood samples were collected for the determination of CD4+,CD8+,natural killer cell (NK cell) and CD4+/CD8+ by flow cytometry 1 day preoperative,2 and 48 h postoperative.Results In two groups,the CD8+ and NK cell of 2 h postoperative were lower significantly than those of preoperative (observation group:0.1850 ±0.0550 vs.0.2430 ±0.0856,0.1197 ±0.0673 vs.0.1598 ±0.0775；control group:0.1219 ±0.0571 vs.0.2385 ±0.0847,0.0778 ± 0.0311 vs.0.1621 ± 0.0806,P ＜ 0.05),however,the observation group was significantly higher than the control group (P ＜ 0.05).There was no significant difference in CD4+,CD8+ and NK cell of 48 h postoperative between two groups.Conclusion There are disorders on the T cell immune functions in postoperative patients with upper abdominal,but flurbiprofen axetil preemptive analgesia can improve the T cell immune function.

Objective: To investigate the relationship between blood level of Galectin-3 and the severity of coronary lesions in patients with coronary artery disease (CAD). Methods: A total of 158 consecutive subjects received coronary artery angiography (CAG) in Yantai Yu huangding hospital were studied and they were divided into 2 groups: Control group,n=38 individuals with normal coronary artery, CAD group,n=120 patients with at least 1 coronary branch stenosis ≥ 50%. CAD group was further divided into 2 sets of subgroups:①By the number of branches involved, as Single vessel disease, n=42, Double vessels disease including LM,n=40 and Triple vessel disease,n=38.②By the quartile of Gensini score as 1st quartile group, the patients with Gensini score ≤ 18.5, 2nd quartile group,18.5 < Gensini score ≤ 45.0, 3rd quartile group, 45.0 < Gensini score ≤ 71.5 and 4th quartile group, Gensini score>71.5,n=30 in each subgroup. Blood levels of Galectin-3 were examined, and the severity of coronary lesions was evaluated by both branch numbers and Gensini score analysis. Results: Compared with Control group, the blood level of Galectin-3 was higher in CAD group,10.66 (5.81, 16.17) ng/ml vs 18.3(1.14, 2.52) ng/mlP<0.01; with the more branches of coronary lesions involved, the blood levels of Galectin-3 increased accordingly, all P <0.01. With the elevation of Gensini score, the levels of Galectin-3increased accordingly, except for the difference between the 3rd quartile group and 4th quartile group, all P <0.01.With adjusted other factors, blood levels of Galectin-3 were positively related to the number of coronary branchlesions (r =0.52, P <0.01) and Gensini score levels (r =0.17, P =0.04).Conclusion: Blood level of Galectin-3 is positively related to the severity of coronary lesions whichimplies that Galectin-3 may have potential detrimental effect on the occurrence and development of coronaryatherosclerosis.

Exposure to thermal environment is one of the main concerns for manned space exploration. By focusing on the works performed on thermoregulation at microgravity or simulated microgravity, we endeavored to review the investigation on space thermal environmental physiology. First of all, the application of medical requirements for the crew module design from normal thermal comfort to accidental thermal emergencies in a space craft will be addressed. Then, alterations in the autonomic and behavioral temperature regulation caused by the effect of weightlessness both in space flight and its simulation on the ground are also discussed. Furthermore, countermeasures like exercise training, simulated natural ventilation, encouraged drink, etc., in the protection of thermoregulation during space flight is presented. Finally, the challenge of space thermal environment physiology faced in the future is figured out.

ObjectiveTo evaluate prognostic factors and the surgical results of pulmonary carcinoid tumors.Methods We retrospectively reviewed the medical records of 62 patients who were diagnosed as pulmonary carcinoid tumors between January 2000 and October 2010 at Department of Thoracic Surgery,Shanghai Chest Hospital.The following information was available for each of the 62 patients:age,sex,pathological type,and TNM stage.ResultsThere were no operative death.The 3-year and 5-year survival rates after surgery were 92.1％ and 77.8％,respectively.Of the 62 patients,42 were diagnosed as typical carcinoid tumor,and among them,4 patients (8.3％) had lymph node metastases.Their 3-year and 5-year survival rates were 97.8％ and 94.7％,respectively.The remaining 20 patients were diagnosed as atypical carcinoid tumor,and among them,6 patients (37.5％) had lymph node metastases.Their 3-year and 5-year survival rates were 84.4％ and 58.8％,which were statistically significant compared with typical carcinoid tumor( P =0.0047 ).There was significant difference in survival rate between the patients with lymph node metastases and the patients without lymph node metastases (P =0.0048).CondusionThe main risk factors affecting survival rate of those patients who were diagnosed as pulmonary carcinoid tumors were pathological types and lymph node metastases.

Objective To assess the effects of eszopiclone (ESZ) on the pentobarbital sodium-induced sleeping time and spontaneous activity in mice exposed to acute hypobaric hypoxia.Methods 120 mice were randomly divided into 6 groups by using two factors 2×3 levels factorial design,in which two factors were interventions (ESZ and 0.9％ sodium chloride,2 levels) and altitudes (800 m,3500 m and 6000 m,3 levels).The pentobarbital sodium-induced sleeping test and the open field test were engaged to assess the effects of ESZ on sleeping time and spontaneous activity.Results (1) The drug and altitude had no interaction in the results of both the pentobarbital sodium-induced sleeping test and the open field test(P＞0.05).(2)The time of pentobarbital sodium-induced sleeping of mice in the groups of ESZ at each altitudes were (37.77± 18.22) min,(37.02± 13.67) min,(95.67±47.68)min and in the groups of NS were(17.78± 14.10) min,(15.09± 12.46) min,(39.54±28.24) min respectively,and the sleep time in ESZ groups were significantly longer than those in the groups of NS (P＜0.05).The time of pentobarbital sodium-induced sleeping were longer in group of 6000 m than those in the other two groups,both the ESZ and NS groups (P＜0.05).(3)No significant difference was found in the open field test between the ESZ and NS groups in the same altitude(P＞0.05) ; while the mice at the altitude of 6000 m in groups of ESZ and NS decreased compared with the groups at the altitude of 800 m after the relevant drugs intra-perineally for 6 h (P＜0.05).Conclusion ESZ may prolong pentobarbital sodium-induced sleeping time especially at the altitude of 6000 m and with no influence on the spontaneous activity in mice exposed to acute hypobaric hypoxia.High altitude at 6000 m may prolong the sleep time induced by pentobarbital sodium and reduce the spontaneous activities.

AIM: To investigate the expression of TCR V? subfamily in T cells in patients with idiopathic thrombocytopenic purpura (ITP). METHODS: The TCR V? 24 subfamily genes were amplified in peripheral blood mononuclear cells from 5 cases with ITP using RT-PCR, to observe the usage of TCR V? repertoire. 10 normal individuals served as controls. RESULTS: Only 4-11 V? subfamily in T cells were identified in ITP cases. The frequent expressions of V? subfamilies were V?2 (100%), V?3 (100%), V?19 (80%) and V?21 (80%), while the expression of V?4, V?6-12, V?17, V?20 and V?24 were not detected. All 24 V? subfamilies were detected in samples from normal individuals. CONCLUSION: The restricted expression of TCR V? subfamilies is one of the T-cell immune features in patients with ITP, indicating that it may be related to the disorder of cellular immune function in ITP.

Previous researches showed that the expression level of E-Cad in most infiltrating cancer cells was reduced or negative. This study explored whether 4HPR restrained the infiltration of bladder cancer cells through regulating the expression of E-Cad. The infiltrating bladder cancer cells T24 were cultured, and then treated by a proper dosage of drug. Their viability was a determined by MTT method. Western blotting and RT-PCR were adopted to detect the changes of E-Cad gene expression at both protein and mRNA levels. Moreover, immunofluorescent staining and confocal fluorescence microscopy were employed for the observation of the expression of E-Cad. The result showed that, at both mRNA and protein levels, the expression level of E-Cad in T24 cells treated by 4HPR was significantly higher than that of control group, while the β-Cat expression was also relocated from the cell nucleus to cytoplasm. Our findings suggested that the regulatory function of 4HPR on infiltration of bladder cancer cells T24 is at least partly achieved by regulating the expression of E-Cad.

Background Increase of lens thickness at incipient cataract is a key factor of onset of primary angle-closure glaucoma (PACG).Phacoemulsification (Phaco) or phacotrabeculectomy (Phacotrabe) have been documented to be effective for the patients of PACG associated with cataract.However,which surgery is more effective and safe is lack of evidence.Objective This study was to assess and compare the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract.Methods The relevant literature was searched electronically from the PubMed (1966 to June 2011),EMB Reviews (1966 to June 2011) and Cochrane Library (Issue 1,2011).The manually searching of relevant conference proceedings was used as the supplement.The articles of randomized controlled trial (RCT) about the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract were included.The methodology quality of included literature was graded.The analysis indexes included intraocular pressure (IOP)-lowing range,postoperative administration of glaucoma drugs,incidence of positive complication,postoperative best corrective visual acuity (BCVA) and perimetry damage.The RevMan4.2 software from Cochrane Collaboration was used for the Meta analyses.Results Three RCTs about phaco versus Phacotrabe for PACG with cataract were selected in this study with the 164 eyes of 164 cases.Meta analysis showed that the IOP-lowing range was larger in the Phacotrabe group compared to only Phaco group with the WMD of 1.17 and 95％ CI of 0.06-2.27 (P =0.040),and the drug dosage of anti-glaucoma was less in the Phacotrabe group in comparison with the Phaco group with the WMD of 0.5 and 95％ CI of 0.24-0.77 (P =0.000).However,the incidence of postoperative complication was higher in the Phacotrabe group than that of the Phaco group with the RR of 0.08 and 95％ CI of 0.02-0.33 (P =0.000).No significant difference was found in the BCVA (WMD =0,95％ CI:-0.13-0.13,P=1.00) andperimetry (WMD =1.01,95％CI:0.56-1.82,P=0.98).Conclusions Compared with Phaco,Phacotrab has a better IOP-lowing effectiveness and slightly worse safety.Phaco and Phacotrab have a fairly influencc in the postoperative BCVA and perimetry.As the sample sizes of the included trials are relatively small,more welldesigned large-scale RCTs are needed.
