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.

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 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.

Objective To understand the prevalence,drug resistance and clinical features of children with acute lower respiratory tract infection(ALRI) caused by escherichia coli.Methods From Oct. 2005 to Oct. 2006,659 patients with ALRI who were admitted to hospital were chosen and their nasopharyngeal secretions were obtained and cultured.K-B disc diffusion for antibiotic susceptibility were performed for these clinical isolates.Results Among 659 patients,118 cases were isolated escherichia coli,the rate was 17.99% which had 90 boys and 28 girls.Eighty-seven of 118 E.coli strains were with extended-spectrum ?-lactamase(ESBLs),the rate was 73.73%.All of strains were sensitive to imipenem.For ESBLs-producing strains,the ratio of resistance tocefotaxime,ceftriaxone,cefuroxime,ampicillin,piperacillin were 78.81%,73.73%,73.73%,76.27%,78.81%,respectively.Conclusions The positive rate of ESBLs producing E coli in Kunming area is high and drug resistance is severe gradually.Imipenem can be the first selection for treatment on these infections.

Objective To investigate the effect of illness severity on preterm infant's hypothalamusputituary-adrenal (HPA) axis, we measured the serum concentration of cortisol,aldosterone and adrenocorticotropic hormone (ACTH). Methods Ninety preterm infants who were transferred to our hospital within 72 hours after birth were involved. These preterm infants were divided into two groups:gestational age (GA) ≥34 weeks' preterm infants and GA <34 weeks' preterm infants. We evaluated these preterm infants at the time of admission,day 7 and day 14 after birth with neonatal critical illness score (NCIS). Then they were divided into mild group and severe group by the lowest score. We measured their serum cortisol,aldosterone and ACTH at the time of admission,day 7 and day l4 after birth. Results (1) The serum cortisol concentration of preterm infants with severe illness was higher than that of preterm infants with mild illness. Among the GA ≥34 weeks' preterm infants,the serum cortisol concentration of preterm infants with severe illness was significandy higher than that of preterm infants with mild illness within 72 hours after birth (t = -2.263,P =0. 029). Among the GA <34 weeks' preterm infants,the serum cortisol concentration of preterm infants with severe illness was significantly higher than that of preterm infants with mild illness on day 14 after birth (t =-2. 913 ,P =0. 006). (2) Among the preterm infants with severe illness,the serum cortisol concentration of the GA≥34 weeks' was significantly higher than that of the GA < 34 weeks' within 72 hours after birth (t =-2. 641 ,P =0. 010) ;the serum cortisol concentration of the GA <34 weeks' was significantly higher than that of the GA≥34 weeks' on the day 14 after birth(t = -2. 189,P =0. 036) . (3) The serum cortisol concentration was significantly decreased in the GA≥34 weeks'preterm infants (F = 4. 679, P =0. 012). (4) The serum cortisol concentration of aldosterone and ACTH was not significantly different between preterm infants with severe illness and those with mild illness. Conclusion The preterm infant already has the ability to respond to stimuli by regulating cortisol secretion. The serum cortisol concentration increases as disease severity worsens.Serum aldosterone and ACTH concentration are not correlated with the severity of the disease.

Objective To investigate the effectiveness and safety of bilateral lobar lung transplantations (LLTx) in thoracic cavity size mismatching patients with end-stage lung diseases and analyze its prognosis.Method Clinical data of 34 patients receiving LLTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2012.LLTx were performed on 14 male and 20 female patients,with a mean age of 37.0 ± 6.3 years (ranging from 15 to 56 years).Indications for LLTx were idiopathic pulmonary fibrosis (n =24),idiopathic pulmonary hypertension (n =2),Eisenmenger syndrome (n =3),bronchiectasis (n =2) and lymphangiomyomatosis (n =3).Amongst them 26 patients received LLTx under extracorporeal membrane oxygenation (ECMO) support and 3 on ECMO as a bridge to transplantation.Twenty-four middle/lower right lobes with left lower LLT,4 bilateral lower LLT,2 bilateral superior LLT and 4 split left lung LLT were performed.Ischemic time was 4.4± 1.2 h for the first lobe and 6.3 ± 1.4 h for the second.Result The mortality in postoperative prophase (30 days) was 23.5％.The 1-,2-,3-and 5-year survival rate after LLTx was 70.9％,60.8％,50.6％ and 36.2％ respectively.The main causes of mortality included primary graft dysfunction,acute rejection,multiple organ failure,bronchiolitis obliterans and sepsis.Lung function test was performed on 23 cases after transplantation and forced expiratory volume in first second,maximal voluntary ventilation accounting for the predicted value was (74.23 ± 4.86)％ and (72.0 ± 3.64)％,respectively.Conclusion This study demonstrates that for thoracic cavity size mismatching patients,LLTx are safe and effective in the treatment of end-stage lung diseases,which can ameliorate the lung function and prognosis.
