Objective To investigate the relationshp among Gp Ⅱ b/ⅡⅢ a、CD62p in platelet activation mark-er and high-sensitivity C-reactive protein (hs-CRP) in elderly patients with chronic cor pulmonary exacerbation. Methods The subjects were divided into four groups (42 elderly patients with cor pulmonary exacerbation,42 eld-erly patients with cot pulmonary remission,30 cases of healthy elderly subjects and 30 cases of healthy non-elderly subjects) . The expression of Gp Ⅱ b/Ⅲ a and CD62p were measured with tricolor flow cytometry. Hs-CRP levels were measured by nephelometry and turbidimetry in patients and normal controls. Results Compared with cor pul-monary remission group,healthy elderly group and healthy non-elderly group, the levels of Gp Ⅱ b/Ⅲ a, CD62p and hs-CRP increased significantly in patients with chronic cor pulmonary exacerbation ( all P < 0.001 ). Gp Ⅱ b/Ⅲ a and CD62p results of the elderly patients with cot pulmonary remission were higher than those in healthy elderly subjects (P <0.05) and healthy non-elderly subjects (P < 0. 001 ) . The expressions of both Gp Ⅱ b/Ⅲa and CD62p in healthy elderly subjects were statistically higher than that in healthy non-elderly subjects ( P < 0.05 ). There was a positive con'elation between the Gp Ⅱ b/Ⅲ a、CD62p and hs-CRP in elderly patients with chronic cot pulmonary exac-erbation(r =0.59,P<0.01 ; r=0.54,P<0.01 ). Conclusions The platelet in elderly patients with chronic cot pulmonary exacerbation is overactivated,which is correlated with hs-CRP.

Objective To study the effect of different cag pathogenicity island in Helicobacter pylori ( Hp ) from Chinese patients and various kinase inhibitors on Hp induced interleukin 8 (IL 8) secretion in Chinese gastric epithelial cells. Method Chinese gastric epithelial cells(MGC 803) were cocultured with Chinese clinical cagA +cagE +, cagA +cagE -,cagA -cagE +,cagA -cagE - Hp in vitro, respectively. At the end of culture, IL 8 protein secretion was assayed by ELISA. The effect of the inhibitor of protein kinase A(PKA), C, G, protein tyrosine kinase(PTK) was analyzed on IL 8 protein secretion in gastric epithelial cells by Hp stimulation. Results cagA +cagE + Hp induced IL 8 protein secretion higher than cagA + cagE - or cagA -cagE + Hp , but cagA -cagE - Hp didn′t increase IL 8 protein secretion in gastric epithelial cells. Further studies with gastric epithelial cell showed that IL 8 protein secretion induced by cagA +cagE + Hp was blocked by the PTK inhibitor herbimycin A but not by PKA inhibitor H7, PKC inhibitor calphostin C, and PKG inhibitor KT5823. Conclusion cagA +cagE + Hp significantly increases IL 8 protein secretion and it depends on PTK activation in gastric epithelial cells.

Objective To explore the effects of continuous renal replacement thempy ( CRRT) on efficacy in severe acute pancreatitis ( SAP) patients based on different time .Methods A total of 38 SAP patients were divided into two groups randomly:early group(CRRT within 48h) for 21 patients and late group(CRRT after 48h)for 17 pa-tients.the APACHE II score,the length of stay ICU and the mortality of 28d were compared between the two groups . Results The APACHE Ⅱscore was significantly higher in late group than that in early group in day 1 and 2 ( t=2.231,2.304,both P<0.05);there is no significant differences between late group than that early group in APACHEⅡscore before treatment(P>0.05);the hospitalizing days and mortality were significantly higher in late group than that in early group(t=2.156,χ2 =4.293,both P<0.05);there was no significant differences between late group and early group in gender,age,APACHEⅡscore(all P>0.05).Conclusion Early CRRT can decrease both the hospi-talizing days and mortality in SAP patients .CRRT may provide more clinical benefits in the early phase (within 48h) of SAP.

Objective To investigate the level of human cytomegalovirus(HCMV)specific CD8+ T lymphoeytes in peripheral blood and the immune reaponae of HCMV reactivation after kidney transplantation.Methods Thirty-eight HCMV seropesitive HLA-A*0201 kidney transplant recipients(9 with HCMV infection and 29 without HCMV infection)and 54 healthy individuals were enrolled.The levels of total HCMV specific CD8+ T cells were measured using HLA-A2 pentamer folded with HCMV-peptide NLVPMVATV.The levels of IFN-γ secreting CD8+ T cells were measured by intracelluhr IEN-γ staining pulsed with the same peptide.Results The median levels of pentamer stained CD8+ T cells were 1.19%(0-19.42%),1.20%(0-18.40%)and 3.2%(0.51%-18.90%)in healthy group,negative HCMV group and positive HCMV group(H=5.34,P＞0.05),respectively.The median levels of IFN-γ secreting CD8+ T cells were 0.72%(0-0.70%),0.47%(0-5.61%)and 0.67%(0.07%-4.00%),respectively(H=0.58,P＞0.05).However,the mean proportions of IFN-γ secreting pentamer stained T cells relative to total HCMV specifc CIL were(60.18±19.16)%,(39.19±17.22)% and(20.02±13.26)%,respectively.There were significant differences among the groups(P＜0.01).Condusiorm There was no significant difference of levels of HCMV specific CD8+ T lymphocytes in peripheral blood between the kidney transplant recipients and healthy individuals.However,the proportion of HCMV-specific IFN-γ producing CD8+ T cells in pentamer stained cells was reduced in the kidney transplant recipients especially in those with active HCMV infection,which may contribute to the inability to control HCMV reactivation.

Objective To study the effect of psychological intervention combined with the analysis of Budesonide and Formoterol Fumarate Powder for Inhalation in treatment of chronic obstructive pulmonary disease. Methods 100 patients with chronic obstructive pulmonary disease treated in our hospital from February 2015 to March 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group was treated with the Budesonide and Formoterol Fumarate Powder for Inhalation treatment,the experimental group on the basis of psychological intervention on the mental status of patients and patients,strengthen communication and exchanges, increase confidence in the treatment and the treatment compliance of patients. Results After treatment, the SGRQ score of the experimental group was (57.33±16.81), and the score of the control group was (43.86±12.68) points, with statistical difference (P<0.05). The scores of depression and anxiety in the experimental group were significantly better than those in the control group,with statistical difference(P<0.05). Conclusion Budesonide and Formoterol Fumarate Powder for Inhalation combined with mental intervention in the treatment of chronic obstructive pulmonary disease can significantly improve the patients, improve the quality of life, help patients recover as soon as possible, has clinical significance.

The effects of estradiol and tamoxifen on the proliferation of estrogen receptor positive cells and the relationship between the tamoxifen tolerance and cell origin were investigated. The tissues of human endometrium and breast cancer were randomly selected following dissection for primary cell culture. After the breast cancer cells and endometrial cells were treated with 1 x 10(-8) mol/L estradiol and/or 1 x 10(-6) tamoxifen, 3H-labelled thymine nucleotide was used to trace the kinetics of cell proliferation. There was no significant difference in the inhibition on the human endometrial cells between tamoxifen-treated group (6.3%) and control group (6.4%), but tamoxifen could significantly inhibit the proliferation of the human breast cancer cells (45.84%) as compared with control group (52.72%). Moreover, tamoxifen could significantly stimulate the proliferation of tamoxifen resistant breast cancer cells (9.64%) as compared with control group (6.32%). Estradiol could significantly stimulate the proliferation of all the three kinds of cells as compare with control group. The combined use of estradiol and tamoxifen could inhibit the proliferation of the endometrial cells and breast cancer cells as compared with estradiol used alone, but on the tamoxifen resistant breast cancer cells, they could more significantly stimulate the proliferation than E2. It was concluded that E2 could stimulate the proliferation of these three kinds of cells. However, the inhibitive effects of tamoxifen on the proliferation of these cells were dependent on the estradiol.

Sensitivity and specificity for the diagnosis of renal impairment were calculated by receiver operating characteristic (ROC) curves for above three parameters.Results Correlation coefficients with ~ 99m Tc-DTPA were-0.744 for serum Cystatin C,-0.658 for serum creatinine, 0.625 for creatinine clearance (all P

Objective To study on the value and safety of early endoscopic retrograde cholangiopan-creatography (ERCP)and endoscopic sphincterotomy (EST) in acute biliary pancreatitis. Methods Ninety-two patients with acute biliary pancreatitis underwent early ERCP (within 72 hours) and received endoscopic therapy (ERCP group). Another 40 patients with acute biliary pancreatitis were treated conservatively without ERCP (control group). The disappearance of abdominal pain, decrease of serum amylase level, the mean days and costs of hospitalization and complications were observed in all patients. Results In ERCP group, all patients were performed EST, stones in 72 choledocholithiasis patients had been removed with net-basket or air pocket. Ten cases of severe acute biliary pancreatitis received endoscopic pancreatic duct stents drainage. Ninety two cases of acute biliary pancreatitis received endoscopic nasal catheter bile drainage. The days of the disappearance of abdominal pain, the decrease of serum amylase levels, the cost of the hospitalization and the days of the hospitalization were significantly shorter in the early ERCP group than in the control group. The mortalities in ERCP and control group were 8. 3% and 33. 3% respectively. Conclusion Early ERCP endoscopic therapy is a safe procedure has the superiorities in lowering the mortality, hospital days and expense.

Objective: To evaluate the application of frontal flap in reconstructing the defect of nose, the clinical data of 12 cases were reported. Methods: Twelve patients with nasal skin cancers undertaking radical dissection of tumor accompanied frontal flap reconstructing one stage were reviewed retrospectively.Results: The overall following\|up rate was 100%, 10 of these patients curled slightly after reconstructing the nose, but influence of the nasal outline was little. Two cases were recurrent locally, one occurred 24 months after operation, the other occurred 38 months. Both of them received radiotherapy. Malformation arised after radiotherapy. The total successful rate of reconstruct nasal outlook was 83.33%, the 3\|year locally recurrent rate was 8.33%,5\|year survival rate ws 100%, 5\|year survival rate without tumor was 83.33%.Conclusion:The blood supply of frontal flap is abundance;healing up soon after reconstruction; the manipulation of surgery is simple and safe.
