Background Pterygium is a relatively common eye disease,but its aetiology and pathogenesis remain uncertain.At present,the study on pterygia focuses on understanding its underlying mechanism.Objective This study was to detect the expression of 8-hydroxy-2'-deoxyguaine (8-OHdG),a marker of oxidative damage of DNA,and bcl-2,a gene related with apoptosis,on the pterygium tissue.Methods Thirty pterygium tissue specimens were obtained during the surgery with the primary pterygium 24 cases and recurrent pterygium 6 cases.In addition,20 normal conjunctival specimens from retinal detachment surgery and strabismus surgery were collected.The expressions of 8-OHdG and bcl-2 in pterygium tissue were detected using immunochemistry and compared with the normal conjunctival tissue.The difference in the expressions of 8-OHdG and bcl-2 among different specimens was compared by x2test,and the relationship between 8-OHdG expression and bcl-2 expression was evaluated by Kappa test.Results The positive expressing rate of 8-OHdG in the pterygium tissue was 62.5％ and 83.3％ in the primary and recrudescence pterygium tissue,respectively,but the expression of 8-OHdG was absent in the normal conjunctiva tissue.No significant difference was found in the positive expressing rate of 8-OHdG between primary and recrudescence pterygium tissue(x2 =0.938,P＞0.05).The bcl-2 expressing rate was 90.0％ and 87.5％ in the primary and recrudescence pterygium tissue,respectively.However,that in the normal conjunctival tissue was absent.No significant difference was seen in the bcl-2 expression rate between primary and recrudescence pterygium tissue (x2=0.833,P ＞ 0.05).Of the 27 pterygium tissue with bcl-2 positive expression,8-OHdG showed the positive expression in 20 specimens,and 3 specimens with the bcl-2 negative response were absent reactive to 8-OHdG,showing insignificant difference between them (P＞0.05).The relationship between 8-OHdG expression and bcl-2 expression was concord in a certein extent (Kappa =0.464).Conclusions The upregulation of 8-OHdG in the pterygium tissue indicates that oxidative damage of DNA plays a role in the development of pterygium.Oxidative damage of DNA caused by ultraviolet may be an upriver factor,which induces raising up of expression of bcl-2 and inhibits the apoptosis of normal cells and further proliferation of the conjunctiva tissue,resulting in the genesis and development of pterysium.

Objective:Studies suggested that some growth factors and their receptors play important roles in the treatment and prognosis of lung cancer.In this study we investigated the expression of epidermal growth factor receptor(EGFR),vascular endothelial growth factor(VEGF),and Ki-67 simultaneously in the tissues of aged patients with non-small cell lung cancer(NSCLC). Methods:The expression levels of EGFR,VEGF,and Ki-67 in 64 cases of aged patients with NSCLC were detected by immunohistochemistry staining.Results:The positive expression of EGFR,VEGF and Ki-67 in the tissue of lung cancer was 59.4%,57.8% and 92.2%,respectively.It is different significantly while compared with control group of benign tissues.The expression levels of EGFR and VEGF are correlated significantly with the pathologic type,differential degree,TNM stage and lymphatic metastasis.The expression level of Ki-67 is related to differential degree and TNM stage of lung cancer.Conclusion:The method of immunohistochemistry to detect multiple biological markers simultaneously is simple and feasible.It can supply important information for the staging and prognoses of patients with NSCLC,and more than that,it can also provide the theoretic basis for the individualized molecular targeting therapy of NSCLC.

Objective To investigate the effectiveness and safety of bilateral lung transplantation with simultaneous lung volume reduction surgery in the treatment on end-stage lung disease and analysis its prognosis.Methods Clinical data of 79 patients with end-stage 1ung diseases receiving BLTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2012.Bilateral lung transplantations were performed on 48 male and 31 female patients, with a mean age of(57.0 ± 6.3) years (ranging from 15 to 75 years).Amongst them 56 patients received LTx under circulation support,including 1 cases of cardiopulmonary bypass(CPB) support and 55 cases of extracorporeal membrane oxygenation(ECMO) support.34 patients accepted lung volume reduction surgery, other 45 patients receive standard BLTx.The Patients were divided into lung volume reduction group(group Ⅰ)and control group(group Ⅱ).Differences in various clinical parameters such as Pulmonary function, postoperative complications, and prognosis between the two groups were compared.Results The 1、2、3 and 5-year survival rate after LTx was 80.5％ 、71.4％ 、58.2％ and 43.5％.The mean survival time post-transplant in size reduction group and control group were(38.54 ±4.72) months and(42.19 ±6.64) months repectively.The main causes of mortality included primary graft dysfunction(PGD) ,acute rejection(AR) , multiple organ failure(MOF) , bronchiolitis obliterans(BOS) and sepsis.No tendency of increase in mechanical ventilation, chest tube drainage time, volume of chest drainage were observed.Compared clinical parameters between the two groups, none had significant differences(P ＞0.05).Lung function test was performed on 63 cases after transplantation.There was no significant difference in FEV1 improvement after lung transplantation between the two groups[(74.23 ±4.86)％, (72.0 ±3.64)％, P ＞0.05].Conclusion This study demonstrates that BLTx with simultaneous lung volume reduction surgery is safe and effective, which have the same outcome and prognosis compare with standardbilateral lung transplantation.

OBJECTIVE To investigate the molecular mechanisms of resveratrol( Res)in renal interstitial fibrosis(RlF)in rats with unilateral ureteral obstruction(UUO). METHODS Forty-eight Spra-gur-Dawley rats were randomly divided into UUO( normal saline,n = 16),UUO with Res treatment (Res,20 mg·kg-1 ,n=16),and sham-operation(sham,n=16)models. The kidneys were excised on the 7th and 14th day. The deposition of collagen fiber in the kidney was detected with HE and Masson staining. The levels of sonic hedgehog(SHH,an inducer of SHH pathway)in kidney tissues were deter-mined by ELlSA. lmmunohistochemical analysis was performed to evaluate the protein expression of SHH signaling-related molecules,including SHH,smoothened(Smo),patched-1(Ptch1),and Gli1, proliferating cell nuclear antigen(PCNA)and matrix component typeⅢ collagen. The mRNA expression levels of Smo,Ptch1 and Gli1 were detected by real-time RT-PCR. RESULTS The degree of RlF observed with HE and Masson staining was obviously increased in UUO kidneys,but decreased in Res-treated kidneys. Enhanced expression levels of typeⅢ collagen and PCNA in UUO rats were suppressed by Res treatment(P﹤0.05). Res administration decreased the expression levels of SHH,Smo,and Gli1 (P﹤0.05),but increased the expression of Ptch1(P﹤0.05),suggesting that Res inhibit the obstruction-induced activation of SHH signaling. CONCLUSION Res can attenuate RlF in UUO rats,and the possi-ble mechanism is that Res down-regulates the activity of SHH signaling and inhibits cellular proliferation, resulting in inhibition of matrix accumulation in renal interstitium of UUO rats.

A novel rapid method for detection of the illicit beta2-agonist additives in health foods and traditional Chinese patent medicines was developed with the desorption corona beam ionization mass spectrometry (DCBI-MS) technique. The DCBI conditions including temperature and sample volume were optimized according to the resulting mass spectra intensity. Matrix effect on 9 beta2-agonists additives was not significant in the proposed rapid determination procedure. All of the 9 target molecules were detected within 1 min. Quantification was achieved based on the typical fragment ion in MS2 spectra of each analyte. The method showed good linear coefficients in the range of 1-100 mg x L(-1) for all analytes. The relative deviation values were between 14.29% and 25.13%. Ten claimed antitussive and antiasthmatic health foods and traditional Chinese patent medicines from local pharmacies were analyzed. All of them were negative with the proposed DCBI-MS method. Without tedious sample pretreatments, the developed DCBI-MS is simple, rapid and sensitive for rapid qualification and semi-quantification of the illicit beta2-agonist additives in health foods and traditional Chinese patent medicines.

Objective To investigate the institution of extracorporeal membrane oxygenation (ECMO) for primary graft dysfunction (PGD) after lung transplantation (LT) and analyze its clinical outcome.Method A retrospective analysis was performed on 22 patients with grade 3 PGD in early stage after LT from September 2002 to December 2013.There were 7 patients with single LT and 15 patients with bilateral LTx.Ventilatory support was used at early stage for 6 cases,and at later stage,ECMO assistant circulation was used for 16 cases.Result Of 6 patients treated by adjusting low volume,high frequency and high positive end expiratory pressure ventilation (PEEP) mode,2 cases reversed,and 4 cases died of respiratory failure.In 16 cases accepting ECMO support,10 cases were given venous-venous mode and 6 cases venous-artery mode.The average flow time was 5.5 days.ECMO was successfully withdrawn in 10 cases and 6 cases died of multiple organ failure,infection and cardiac arrest.Conclusion The high incidence of PGD causes high mortality peri-operatively after LT.Preventing ECMO can improve the survival rate of the lung transplant patients.Once PGD happens,appropriate treatment should be given as soon as possible.ECMO can effectively promote the transplanted lung function recovery,and reduce the perioperative mortality.If the indications of ECMO use was reached,the institution of ECMO should be used as soon as possible.
