Objective To investigate the expressions of Stat3, CyclinD1 and proliferating cell nuclear antigen (PCNA) in non-small cell lung cancer (NSCLC), and analyze their relationships with carcinogenesis and progression of NSCLC. Methods SP immunohistochemistry was used to detect the expressions of Stat3, CyclinD1 and PCNA in 45 cases of NSCLC. Results The positive rate of Stat3 was 71. 1 % in NSCLC. The expression intensities of Stat3 was not associated with different tumor sizes and histological type, but it was associated with the expression intensities of CyclinDi and PCNA (r= 0.531, P

Objective:To observe the effect of electroacupuncture(EA)combined with repetitive transcranial magnetic stimulation(rTMS)on limb dysfunction in ischemic stroke patients. Methods:A total of 63 stroke patients were divided into an observation group and a control group using the random number table method.Thirty-one patients in the control group were treated with routine Western medicine combined with rTMS;32 patients in the observation group were treated with EA in addition to the intervention in the control group.The duration of treatment was 3 months.The National Institutes of Health stroke scale(NIHSS),the Fugl-Meyer assessment(FMA),the modified Barthel index(MBI),and the motor evoked potential(MEP)latency of transcranial magnetic stimulation were observed before and after treatment in both groups. Results:Two cases withdrew from the observation group and 1 case withdrew from the control group.After treatment,the NIHSS score in both groups was lower than that before treatment,the FMA and MBI scores were higher than those before treatment,and the latency period of MEP was shorter than that before treatment,and the differences were statistically significant(P<0.05).After treatment,the NIHSS,FMA,and MBI scores and MEP latency period of the observation group improved more than those of the control group,and the differences between the groups were statistically significant(P<0.05). Conclusion:EA combined with rTMS can improve the motor function of limbs in ischemic stroke patients and improve their self-care ability.The mechanism may be related to increasing the excitability of the motor cortex and improving the electrophysiological function of the central nervous system.

AIM: To investigate the effect of deoxycholic acid (DCA) on the energy metabolism in human normal colon epithelial NCM460 cells.METHODS: NCM460 cells was treated with DCA at 10, 30 and 100 μmol/L for 5 d, or DCA at 100 μmol/L for 3, 5 and 7 d.After treated with DCA at 100 μmol/L for 3 d, the cells were treated with resveratrol, the activator of sirtuin 3 (SIRT3), for the next 4 d.Adenosine triphosphate (ATP) production in the mitochondria and lactate acid level were detected.The protein expression of SIRT3 was determined by Western blot.RESULTS: DCA inhibited the ATP production, increased lactate acid level, and downregulated the protein expression of SIRT3 in a dose-and time-dependent manner.Resveratrol at 10 μmol/L reversed the effects of DCA on the NCM460 cells.CONCLUSION: DCA induces the dysfunction of energy metabolism in NCM460 cells, and the mechanism may be related with SIRT3.

Objective To evaluate the diagnostic value of acetic acid spray combined with narrow-band imaging ( NBI) for early gastric cancer and precancerous lesion. Methods A total of 136 gastric cancers and precancerous lesions from 132 patients detected by screening endoscopy from November 2015 to November 2017 in Guangming Chinese Medicine Hospital of Pudong New Area, Shanghai were enrolled in this study, and were divided into NBI group, acetic acid spray group, and acetic acid spray combined with NBI group ( combination group) . The image clarity, microsurface pattern, microvascular pattern, demarcation line, and mucosal whitening time were observed, and value of the 3 methods in diagnosis of early gastric cancer and precancerous lesions was analyzed. Results Image clarity of micro glandular in combination group was significantly better than that in NBI group and acetic acid spray group (χ2=8. 766, P=0. 003;χ2=5. 273, P=0. 022) , and image clarity of microvascular in combination group was significantly better than that in NBI group (χ2=7. 457, P=0. 006) . The overall diagnostic coincidence rate with pathology of combination group, NBI group, and acetic acid spray group was 91. 9％(125/136), 85. 3％(116/136), and 89. 7％(122/136), respectively. The diagnostic sensitivity of irregular or missing microsurface, irregular or missing microvascular, obvious demarcation line, mucosal whitening time <30 s for carcinoma ( including high grade intraepithelial neoplasia, early carcinoma and infiltrating carcinoma ) were 92. 3％, 91. 3％, 92. 3％ and 90. 4％, respectively, in the combination group, and the diagnostic specificity of above indicators were 93. 8％, 93. 8％, 96. 9％ and 90. 6％, respectively, accuracy were 92. 6％, 91. 9％, 93. 4％ and 90. 4％, respectively. For observation of microsurface, the combination group was superior to the NBI group (χ2 =7. 378, P=0. 007) , but there was no significant difference compared with the acetic acid spray group (χ2=0. 427, P=0. 513);the acetic acid spray group was superior to the NBI group (χ2=4. 405, P=0. 036) . For observation of microvascular, the combination group was not significantly better than the NBI group (χ2=2. 398, P=0. 122). For observation of demarcation line, the combination group was not significantly better than the NBI group (χ2=2. 722,P=0. 099) and the acetic acid spray group (χ2=0. 216, P=0. 642). There was no difference between the acetic acid spray group and the NBI group (χ2=1. 433, P=0. 231) in observation of demarcation line. Conclusion Acetic acid spray combined with NBI has a good consistency with pathological results with high diagnostic sensitivity and specificity, and can clearly show microsurface of early gastric cancers and precancerous lesions compared to single NBI.

Objective:To analyze the predictive factors of GGU between biopsy and radical prostatectomy pathology based on 2014 ISUP grouping system, then establish and evaluate nomogram.Methods:Patients undergoing radical prostatectomy in Shanghai Ruijin Hospital from March 2012 to March 2019 were reviewed, and the clinical and pathological information were collected. Age(68.1±7.2), body mass indes(BMI) (24.2±3.2)kg/m 2, prostate specific antigen(PSA) 11.5(6.7-20.4)ng/ml, prostate specific antigen destiny(PSAD) 0.35(0.20-0.66). Before March 2017, the number of biopsy cores were 6 to 8; After then, all patients toke 12 cores systemic biopsy. Based on 2014 ISUP grouping system, the differences between biopsy and radical prostatectomy grades were counted. The independent predictors of GGU were analyzed by univariate and multivariate logistic regression analysis, then the nomogram for predicting GGU were established and evaluated. Results:429 patients were enrolled. There were 161 (37.5%) patients in GGU group and 268 (62.5%) patients in non-GGU group. After multivariate logistic regression analysis, body mass index (BMI)>28 kg/m 2( OR=2.54, P=0.021), prostate specific antigen density (PSAD)( OR=1.65, P=0.018)and 2014 ISUP grouping sysyem ( OR=0.53, P<0.001) of biopsy specimen were independent impact factors of GGU. The predicting model was established according to BMI, PSAD and 2014 ISUP grouping system. The area under the ROC cure of the model was 0.735 (95% CI 0.681-0.789). The nomogram model was well calibrated, with the mean absolute error of 6.7%, which means the prediction of GGU is fairly consistent with the actual situation. Conclusions:Based on the 2014 ISUP grouping system, BMI>28 kg/m 2, PSAD and 2014 ISUP grouping of biopsy specimen were independent predictors of GGU. The nomogram model for predicting GGU has a good statistical significance.
