Objective To evaluate the significance of fiberoptic bronchoscopic brush cytology in the diagnosis and histological classification of lung carcinoma.Methods Data of 309 patients with lung carcinoma were retrospectively analyzed.Both bronchoscopic cytology and histology diagnosis were available.The positive rate of bronchoscopic cytology and tissue biopsy were calculated respectively.The classification accuracy of cytological diagnosis for lung carcinoma was evaluated.In tissue biopsy standard,evaluated the significance of bronchoscopic cytology in diagnosis and histological diagnosis.Results The positive rate of bronchoscopic cytology and tissue biopsy were 86.1％ (266/309) and 83.8％ (259/309),respectively.Bronchoscopic cytology combined with bronchial biopsy could obviously improve the positive rate to 94.2％ (291/309) in lung carcinoma diagnosis.Taking the tissue biopsy histological type as a standard,the cytotyping accuracy for brush method was 85.1％(74/87) in squamous carcinoma,82.4％(108/131) in adenocarcinoma and 100％(11/11) in small cell carcinoma for higher.However,the accuracy in diagnosing poorly differentiated carcinomas was only 12.2％ (5/ 41).Conclusion Fiberoptic bronchoscopic brush cytology plays an stable and important role in diagnosing lung carcinomas and histological type determination.However,it has limited use in diagnosing poorly differentiated carcinomas.

Objective To study the expression changes and significance of human telomerase reverse transcriptase (hTERT)-mRNA and mutant p53 protein in thyroid carcinoma tissues in the elderly.Methods The expression level of hTERT-mRNA was examined by in situ hybridization in 50 samples of thyroid carcinoma tissues from the elderly and 41 samples of thyroid carcinoma tissues from the non-elderly and 30 samples of thyroid benign lesions.The expression level of p53 was examined by immunohistochemistry in all subjects.Results The positive rate of hTERT-mRNA was 96.0％ (48/50),85.3％ (35/41) and 10.0％ (3/30) in thyroid carcinoma tissues from the elderly,the non-elderly and thyroid benign lesions respectively,and there were significant differences between the three groups (x2=73.61,P=0.000).The positive rate of p53 was 92.0％ (46/50),85.3％ (35/41) and 13.3％ (3/30) in thyroid carcinoma tissues from the elderly,the non-elderly and thyroid benign lesions respectively,and there were significant differences between the three groups (x2 =62.30,P =0.000).Conclusions The positive rates of hTERT-mRNA and p53 in thyroid carcinoma tissues are higher in the elderly than in the non-elderly,which can be used to evaluate the biological behavior and prognosis of thyroid carcinoma in the elderly,and they play the important roles for targeted therapy.

Objective To investigate the association of single nucleotide polymorphism (SNP) rs13333226 in uromodulin (UMOD) gene with diabetic kidney diseases (DKD) in Han population in Tianjin,China.Methods A total of 210 type 2 diabetes (T2DM),90 normal controls (NC) and 280 DKD patients were recruited.According to the level of estimated glomerular filtration rate (eGFR),the DKD subjects were further subdivided into three groups:GFR≥90 ml/min group (n=105),60 ml/mim≤GFR ＜ 90 ml/min group (n=84) and GFR ＜ 60 ml/min group (n=91).Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for UMOD rs13333226C genotyping.Results The frequencies of AA,GA,GG genotype were 27.8％,58.9％,13.3％ in NC group and 41.0％,48.6％,10.5％ in T2DM group and 54.3％,36.1％,9.6％ in DKD group.The frequency of G allele was 42.8％ in NC group,34.8％ in T2DM group and 27.7％ in DKD group.The genotype distribution of UMOD was statistically significant between NC group and DKD group,and between T2DM group and DKD group (P ＜ 0.05).G allele of UMOD was an independent protective gene polymorphism of DKD in Logistic regression (B=-0.248,Wald=8.012,P=0.021,OR=0.780,95％ CI 0.612-0.968).Conclusion The G allele of UMOD gene may be an independent protective factor of DKD in Han population in Tianjin,China.

Objective To investigate whether Th17/Treg imbalance existed,and whether VEGF165 attenuated the imbalance in allogeneic skeletal myoblasts transplantation(allo-SMT) for acute myocardial infarction (AMI).Methods There were 60 C57BL/6 male mice,3 to 4 weeks old,weighting 0.016-0.020 kg.On the day 1,2,4,and 7 after allo-SMT,the percentages of Th17 and Treg cells,and the ratios of Th17/Treg cells were analyzed by FCM in AMI group,AMI-S group(alloSMT) and AMI-Ⅴ group(with VEGF165 treatment).Subsequently,related proinflammatory and regulatory cytokines and key transcription factors ROR-γt mRNA and Foxp3 mRNA expression were examined by Bio-plex and RT-PCR respectively.Results On the day 1,2,4,and 7 after allo-SMT,the percentage of Treg,related cytokines concentrations and transcript factor Foxp3 mRNA in AMI-S group were lower than those in AMI group,while the AMI-Ⅴ group were higher than those in AMI groups.However,the percentage of Th17 cells,related cytokines concentrations,and ROR-γt mRNA in AMI-S group were higher than those in AMI group; but the AMI-Ⅴ group were lower than those in AMI group.Apparently,compared with AMI group,the ratios of Th17/Treg significantly ascended in AMI-S group and decended in AMI-Ⅴ group.Conclusion Th17/Treg imbalance participated in the formation and development of inflammation and immune response after allo-SMT.However,transfected VEGF165 could relieve the severity of Th17/Treg imbalance.

Objective: To develop a scoring system for estimating advanced colorectal neoplasm risk in average-risk population in southern Jiangsu province, and to evaluate its screening efficiency. Methods: An average-risk population of colorectal neoplasm in southern Jiangsu province, who underwent colonoscopy, was included in this study. All participants were asked to complete a questionnaire on demographic characteristics, medical history, smoking, alcohol consumption, dietary intake, and other factors that may be associated with advanced neoplasms. A multivariable logistic regression method was used to identify independent predictors of advanced neoplasms. A scoring system was developed from the logistic regression model by using a regression coefficient-based scoring method, and then was internally validated. The screening efficiency of the scoring system was assessed by its calibration, discrimination, and accuracy. Results: A total of 905 average-risk participants were included in this study. The scoring system comprised 5 variables (age, sex, coronary artery disease, egg intake, and defecation frequency), with scores ranging from 0 to 10. The system had good calibration (P= 0.205) and good discrimination (area under the receiver operating characteristic curve = 0.75, 95% confidence interval: 0.69-0.82). If score 2.5 was used as the screening cut-off value, the sensitivity, specificity, accuracy rate, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were 93.8%, 47.6%, 50.1%, 9.1%, 99.3%, 1.79, and 0.13, respectively. Among the participants with low-risk (0-2) or high-risk (>2) scores, the risks of advanced neoplasms were 0.7% and 9.1% (P<0.001), respectively. If colonoscopy was used only for persons with high risk, 93.8% of persons with advanced neoplasms would be detected while the number of colonoscopies would be reduced by 45.4%. Conclusion: The scoring system in this study has satisfactory screening efficiency and can be used for preliminary screening of advanced colorectal neoplasms in average-risk population in southern Jiangsu Province.

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.
