Journal of Clinical Surgery 2014;(10):746-748
Objective To investigate the prognostic value of modified Glasgow prognostic score(mGPS)in patients with gastric cancer.Methods The clinical data of 600 patients with gastric cancerwho underwent surgical treatment were retrospectively reviewed.These patients were divided into themGPS0 group,mGPS1 group,and mGPS2 group according to the standard of mGPS.Postoperative survivals and risk factors that may affect patient's prognosis were analyzed among the three groups.Results There were 46 (7.7%)cases,33 (5.5%)cases and 521 (86.8%)cases in the mGPS0,mGPS1 andmGPS2 group,respectively.Except for gender(P =0.203),age,BMI,CEA,CA199,CRP,Alb,TNM stageand mGPS affected the over all survivals and there were significant differences among the groups(P <0.01).Gender,age,BMI,CEA,CA199 and TNM stage affected the mGPS and there were significantdifferences among the groups(P <0.01).Multivariate analysis identified that age(OR,1.319,95% CI1.068,1.629,P <0.01),TNMstage(OR,2.909,95% CI 2.616,3.234,P <0.01)and mGPS(OR,1.845,95% CI 1.184,2.875,P =0.007)were correlated with the postoperative death rate and they wererisk factors of poor postoperative prognosis(P <0.01).Conclusion mGPS can be used as an early,simple and effective prognostic predictor of postoperative survival for patients with gastric cancer.

In the study, the inhibitory effect of epigallocatechin gallate (EGCG) on Calcium oxalate nephrolithiasis and its possible mechanism were investigated. The rat Calcium oxalate nephrolithiasis model was induced through the combined oral administration of ethylene glycol and ammonium chloride, which was intervened with EGCG. Rat blood samples were collected to detect blood creatinine (Cr), blood urea nitrogen (BUN) and blood calcium. Rat urine samples were collected to observe and compare 24-hour urine volume, oxalic acid (Ox) and calcium in urine. Renal samples were collected to prepare tissue slices and observe the pathological changes in Calcium oxalate nephrolithiasis. The expression of osteopontin (OPN) in renal tissues was evaluated by Real-time PCR and Western blot. According to the results, compared with normal rats, rats in the nephrolithiasis model showed significant increases in Cr, BUN, urine Calcium, urine Ox and renal OPN expression (P < 0.05), but obvious decrease in 24-hour urine volume (P < 0.05); Compared with rats with nephrolithiasis, those processed with EGCG revealed remarkable declines in Cr, BUN, urine Calcium and urine Ox (P < 0.05), with significant rise in 24-hour urine volume (P < 0.05) in a concentration-dependent manner. Additionally, compared with the control group, nephrolithiasis rats showed significant pathological changes in Calcium oxalate calculus. After ECCG treatment, the renal pathological changes and OPN expression attenuated significantly in a concentration-dependent manner. The results showed that EGCG inhibits the formation of calcium oxalate nephrolithiasis in rats and shows a notable protective effect on renal functions.

Objective To investigate the correlation of clinicopathological features with osteopontin and aquaporin-1 expres-sion in laryngeal carcinoma.Methods From August 2011 to December 2014 in Dongfeng General Hospital,80 laryngeal cancer specimens and adjacent normal tissue samples were selected,all samples were carried out osteopontin and aquaporin Immunohistochemical analysis expression and clinicopathological characteristics and correlation analysis.Results Osteopon-tin staining particles and aquaporin-1 were located in the stromal cells,yellow dye.In cancer tissue,osteopontin and aquapor-in-1 positive granules were mainly located in the cytoplasm of cancer cells,diffuse shading,coloring deeper place near nests. The positive expression rates of osteopontin and aquaporin-1 in the laryngeal carcinoma were 70.0% and 56.3% respective-ly,the positive rates in the adjacent tissues were 5.0% and 7.5% respectively that compared to the differences were statisti-cally significant (P <0.05).In 80 cases of laryngeal carcinoma.The expression of osteopontin and aquaporin-1 in different clinical stages,differentiation and lymph node metastasis tissues were statistically significant (P <0.05).Spearman correla-tion analysis showed that the osteopontin and aquaporin-1 in laryngeal carcinoma were positively correlated (P <0.05).Con-clusion Osteopontin and aquaporin-1 expression in laryngeal carcinoma were showed high status,and the clinical stage,de-gree of differentiation and lymph node metastasis were significantly correlated that can work together to promote tumor inva-sion and metastasis.

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.
