The results of semi-quantitative analysis in different pathological types of lung cancer hadn’t obvious difference. The curative efficacy of the patients with low uptake was better than that of the patients with high uptake in 65 patients underwent chemotherapy, difference of which had significant(P

Background Diabetic retinopathy (DR) is a common complication of diabetic mellitus,but its pathogenesis is still unclear.Adiponectin may restrain inflammatory reaction and reduce adhesion of vascular endothelial cell to influence diabetic microangiopathy.Relation between adiponectin and nitric oxide synthase (NOS)is less reported.Objective This study was to observe the effect of adiponectin on the expression of NOS in the retinas of diabetic rats.Methods Forty 8-10 weeks Sprague-Dawley (SD) female rats were collected.The rats were randomized into the normal control group (10 rats),adiponectin group (15 rats) and diabetic model control group (15 rats) using the random number table method.Tetraoxypyrimidine was intraperitoneally injected to establish the diabetic model in the rats of the adiponectin group and diabetic model control group,and 10 μg/kg of adiponectin was then injected into the rats of the adiponectin group.Western blot was used to detect the expression of the adiponectin protein in the rat retinas,and the expression of NOS in rat retina was located by immunochemistry.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The relative amount of adiponectin (adiponectin/β-actin)in the retinas was 0.85 ± 0.21,0.79 ± 0.17 and 0.42 ± 0.08,respectively,in the normal control group,adiponectin group and diabetic model control group,with significant differences among the 3 groups (F =4.236,P =0.000).The adiponectin/β-actin ratio in the retinas of the diabetic model control group was significantly declined in comparison with the normal control group and adiponectin group (q =6.615,P =0.000 ; q =6.026,P =0.000).The NOS levels (A value) in the retinas were 0.244 ± 0.035,0.262 ± 0.032 and 0.367 ± 0.066,respectively,in the normal control group,adiponectin group and diabetic model control group,showing a significant difference among them (F =3.752,P =0.001).The A value of NOS in the diabetic model control group was significantly increased in comparison with the normal control group and adiponectin group (q =3.488,P =0.002 ; q =3.079,P =0.005).NOS expression was localized to the inner nuclear layer and retinal ganglion cell layer.Conclusions Adiponectin reduces NO content in diabetic rat retinas by regulating NOS expression.

Purpose To study clinicopathologic feature of prostate cancer by complete embedding of radical prostatectomy specimen. Methods 108 cases of radical prostatectomy by systematic whole organ embedding were reviewed. Results The patient age ranged from 55 to 80 years ( mean 68. 1 years) . The preoperative average PSA value was 18. 3μg/ml. 59 cases ( accounting for 54. 6% of all prostatectomy cases) were in pT2 stage, while 23. 7% (14/59) in pT2a stage, 8. 5% (5/59) in pT2b, and 67. 8% (40/59) in pT2c. 49 cases (45. 4%)in pT3 stage, while 59. 2% (29/49) in pT3a, 40. 8% (20/49) in pT3b. 3. 6%(3/84)cases presented pelvic lymph node metastasis. 8. 3% (9/108) cases were graded as Gleason Score 6 or less, 61. 1% Gleason Score 7, 30. 6%(33/108)Gleason Score 8 or more. Gleason Pattern 5 component was found in 26. 9% (29/108) cases. Positive margin was observed in 25. 9% (28/108) cases, with 75% (21/28) in pT3 stage and 53. 6% (15/28) having Gleason Pattern 5. Patient in pT2 stage pres-ented mean PSA value of 14. 00 μg/ml, involved in no more than 2 biopsy cores in 68. 5% cases, and more than 5 cores in 4. 3%, while in pT3 stage, presented mean PSA value of 23. 82μg/ml, involved in no more than 2 cores in 19. 6%, and more than 5 cores in 28. 3%. The difference of involved core number was significant in pT2 and pT3 tumors ( P<0. 01 ) . 81. 3% cases graded Gleason Score 6 in biopsy was assigned to Gleason Score 7 or more in prostatectomy. Conclusions Completely sampling radical prostatectomy specimen should be recommended for accurate staging and margin status. Preoperative PSA value, Gleason Score of biopsy, involved core number by cancer is a still helpful parameter for clinical staging and risk estimate.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

Purpose To study the prevalence and feature of EGR gene rearrangement in prostatic carcinoma. Methods 242 consecu-tive core biopsies of prostatic carcinoma were evaluated. All biopsy specimens contained 6-14 cores from left and right sides separately delivered. The patient age ranged 58 to 91 years, and PSA value 5 ng/ml to more than 5 000 ng/ml. Immunohistochemistry ( IHC) for ERG protein overexpression and fluorescent in situ hybridization ( FISH) for ERG gene rearrangement were performed. Results 42 cases were detected positive for ERG by IHC ( positive rate 17. 4%) , and positive for ERG rearrangement by FISH either, with 19 ca-ses showing fusion through deletion and 23 through insertion, while no negative cases by IHC demonstrated positive by FISH. 5 cases revealed positive and negative staining in different carcinoma foci of ERG. No ERG positive staining and rearrangement were found in adjacent benign glands. Of positive cases, 12 cases were graded as Gleason score 6, 23 Gleason score 7, and 7 Gleason score 8 or more. Positive rate was 19. 6% in the group of PSA value less than 100 ng/ml, and 10% of more than 100 ng/ml, whereas 17. 2% in the group of clinical T3 stage or less, and 19% of clinical T4 and lymph node or remote metastasis. ERG rearrangement was associated with lower Gleason score, but not with PSA value, clinical stage and progression using theχ2 test analysis. Conclusions IHC is relia-ble for detection ERG rearrangement and helpful for interpretation of prostatic carcinoma. Multiple foci are common in prostatic carcino-ma. There is no significance between ERG rearrangement and disease prognosis.

Background Oxidative damage may cause the functional dysfunction and death of retinal vascular endothelial cells(RVECs),and further leads to the development of retinal vascular diseases.Fufang xueshuantong has a therapeutic effect on retinal vascular diseases,but little is known about its molecular mechanism.Objective The goal of this study was to investigate the protective effects and mechanism of fufang xueshuantong on injury of human RVECs induced by tert-butyl hydroperoxide(t-BHP).Methods Human RVECs were isolated from healthy donor eyes and primarily cultured and then identified by flow cytometry.The third to fifth generations of cells were used in this experiments.The fufang xueshuantong solution of 0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L were added in the cuhure plate with 5 × 104/L cells respectively in the experimental groups,and t-BHP of 75,100,200 and 300 μ.mol/L were added in the model control groups.MTT was used to detect the A490and survival rate of RVECs.The apoptotic rate and death rate of the cells were evaluated by double staining of Annexin V-FITC/PI.Morphology of human RVECs were examined using invert microscopy and Hoechst33258 staining.The expressions of nitro tyrosine (a marker of oxidative damage of protein)and 8-OHdG(a marker of oxidative damage of DNA)in human RVECs were assessed by the immunofluorescence staining.Western blot was used to detect the expressions of nuclear factorkappa B(NF-KB),p53,bcl-2 and bax after 6,12,24 hours t-BHP action.This study was approved by the Ethic Committee of Zhongshan Ophthalmic Center.Results No significant difference was found in A490value among the normal control group,0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L fufang xueshuantong groups(F =1.989,P＞0.05).The survival rates of the cells were lower in 75,100,200 and 300 μmol/L t-BHP groups compared with corresponding fufang xueshuantong groups(t =14.57,13.82,21.51,32.64,P＜ 0.01).The percentages of normal cells were evidently lower in 75,100,200 and 300 μmol/L t-BHP compared with corresponding fufang xueshuantong groups(t=14.908,5.495,17.165,26.330,P＜0.01).The numbers of deformation and death of the human RVECs increased as the elevated concentration of t-BHP,but those in fufang xueshuantong groups were less than the t-BHP groups under the invert microscopy.Compared with t-BHP groups,the expressions of nitro tyrosine,8-OHdG,NF-KB,p53 and bax were lower but the expression of bcl-2 was higher in human RVECs with the statistically significant differences(P＜0.05).Fufang xueshuantong at the concentration of 0.2500 g/L showed maximally protective effect on human RVECs.Conclusions Fufang xueshuantong protects human RVECs against the t-BHP-induced injury through downregulating the expression of NF-kB,p53,bax and up-regulating the express of the bcl-2 protein.
