Objective To study the application of ABCD3-I score in predicting the risk of early is-chemic stoke after transient ischemic attack (TIA) .Methods One hundred and eighty-two carotid TIA patients were divided into low risk group (n=40) ,moderate risk group (n=74)and high risk group (n=68) according to their ABCD2 ,ABCD3 and ABCD3-I scores .The incidence of ischemic stroke was observed within 7 days after TIA .Results The area under the ROC curve for ischemic stroke within 7 days after TIA was 0 .625 ,0 .713 and 0 .831 ,respectively .Twenty-seven patients (14 .8% ) developed ischemic stroke within 7 days after TIA .The incidence of ischemic stroke was significantly higher in moderate and high risk groups than in low risk group and in high risk group than in moderate risk group (6 .8% vs 0% ,32 .4% vs 0% ,32 .4% vs 6 .8% ,P< 0 .01) .The ABCD3-I socre was positively related with the incidence of ischemic stroke within 7 days after TIA (r=0 .486 ,P<0 .01) ,suggesting that ABCD3-I socre could significantly affect the incidence of ischemic stroke within 7 days after TIA (P<0 .05) .Conclusion ABCD3-I score can effectively predict the risk of early ischemic stroke after TIA ,and can thus be used in assessment and treat-ment of T IA .

Autophagy is a classical regulatory mechanism of energy metabolism and self-update system in the maintenance of the intracellular homeostasis and cell development. Autophagy has been recently found to play a role in tumor development. Autophagy regulates tumor formation, proliferation, metastasis, and metabolism. At the same time, the anticancer drugs formed with autophagic mediators have been used in the treatment, which suggested that improving autophagy activity to inhibit tumor has become a new way for cancer treatment of cancer patients. This article gives an overview of the regulatory mechanism of autophagy, the relationship between autophagy and tumor, and tumor therapy by targeting autophagy.

Epithelial-mesenchymal transition (EMT) refers to tne transition during which epithelial cells undergo the loss of apical-basal polarity, acquisition of migration capability and transformation into mesenchymal cells. EMT induces breast cancer in situ to developing into metastasis and associates with the drug resistence. The multiple elements including signal pathways, transcriptional factors and downstream genes orchestrate the transition. Among them, the transforming growth factor β (TGF-β) signaling pathway plays a key role in the regulation of EMT in breast cancer. And this paper reviews the development of TGF-β signaling pathway induced EMT in breast cancer.

BackgroundThe research of corneal thickness after pars plana vitrectomy in DM patient plays an important role not only theoretically but clinically.Objective Present study was to evaluate the change in corneal thickness after pars plana vitrectomy.Methods A prospective coherent study was designed.Seventy-five eyes of 70 consecutive diabetic retinopathy(DR) patients were collected in Tianjin Medical University Eye Center.Pentacam was used to assess the central and periphery corneal thickness by the same investigator preoperatively and 7 days,1 and 3 months postoperatively,respectively.The thickness values from five corneal zone were obtained,including cornea vertex,the thinnest point of the cornea,periphery cornea near the scleral incision of 4 mm away to vertex of cornea on vertical and 240°,120°,60° meridian ( right eye) or 300°,120°,60° meidian ( left eye ).These results were compared and analyzed with ANOVA of repeated measurement data.Subgroup analysis was performed to evaluate the influence of different corneal positions,the use of conventional 20g or 23g transconjunctival sutureless vitrectomy(TSV) groups,surgery duration,gas or fluid endotamponde on corneal thickness.This study was approved by Ethic Committee of this hospital.Written informed consent was obtained from the subjects before any relative medical procedure.Results The mean corneal thickness was ( 639.9 ± 103.1 ),( 689.5 ± 119.3 ),( 666.5 ±113.7),( 650.8 ± 108.6 ) μm before operation,postperative 7 days,1 and 3 months respectively.As covariates appearing in the model,the corneal thickness change rates were revised as the parameters as following: diabeitc duration =13.0 and age =57.2.The revised corneal thickness was significant different among various time points( F=210.928,P=0.000) and different corneal zones(F=24.843,P=0.000) with the size order in turn P4＞P3＞P1＞P2＞P5.The corneal thickness change rates were less in 23g TSV group compared with conventional 20-g group (F =53.843,P =0.000) and BSS tamponade group compared with gas tamponade group ( F =5.288,P =0.022).But no significant difference was found in the revised corneal thickness among surgery duration ＜ 1 hour group,1-2 hour group and ＞2 hour group( F=1.233,P =0.293).ConclusionsVitrectomy is a safe procedure on the ground of cornea,but TSV and fluid endotamponade appear to be more beneficial to the protection of cornea.Pentacam could offer the reliable data in not only central cornea but also periphery cornea.

Objective:To investigate the predictive value of 18F-fluorodeoxyglucose (FDG) PET/CT metabolic parameters for occult lymph node metastasis (OLM) in non-small cell lung cancer (NSCLC). Methods:A total of 183 patients (72 males, 111 females; age (61.5±8.4) years) who underwent 18F-FDG PET/CT and preoperatively diagnosed with clinical N0 stage (cN0) in Third Affiliated Hospital of Soochow University from January 2013 to December 2018 were retrospectively enrolled. All patients underwent anatomical pulmonary resection with systematic lymph node dissections within 3 weeks after 18F-FDG PET/CT examinations. According to the presence or absence of lymph node metastasis, patients were divided into OLM positive (OLM+ ) group and OLM negative (OLM-) group. Parameters of primary lesions, such as the maximum diameter (D max), tumor sites, morphological features, maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), metabolic total volume (MTV), total lesion glycolysis (TLG), tumor SUV max to liver SUV mean (TLR max), tumor TLG to liver SUV mean (TLR TLG) were analyzed. Mann-Whitney U test and χ2 test were used to compare the parameters between groups. Multivariable logistic regression was used to analyze the independent risk factors for OLM. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of different parameters. Results:Among 183 patients, 25 (13.7%, 25/183) of them were diagnosed as OLM. In OLM+ group, 46 lymph nodes were pathologically positive for metastasis, including 15 N1 disease and 31 N2 disease. D max (2.9(2.3, 3.7) vs 2.3(1.7, 2.8) cm), lobulation ((76.0%(19/25) vs 37.3%(59/158)), SUV max (11.1(7.9, 17.7) vs 4.7(2.3, 9.2)), TLG (41.5(10.2, 91.1) vs 15.6(6.5, 23.8) ml), TLR max (4.7(3.5, 7.6) vs 2.1(0.9, 4.0)) and TLR TLG (18.1(5.0, 44.3) vs 6.1(3.0, 11.4) ml) of the primary lesions in OLM+ group were significantly higher than those in OLM-group ( z values: from -4.709 to -3.247, χ2=13.190, all P<0.05). Multivariable logistic regression analysis showed that TLR max (odds ratio ( OR)=15.145, 95% CI: 3.381-67.830, P<0.001) and D max ( OR=3.220, 95% CI: 1.192-8.701, P=0.021) were independent risk factors for OLM. TLR max yielded the highest area under curve (AUC; AUC=0.794) with the threshold of 3.12, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for predicting OLM were 92.0%(23/25), 63.3%(100/158), 67.2%(123/183), 28.4%(23/81) and 98.0%(100/102), respectively. Conclusions:TLR max of tumor is the independent risk factor for OLM in NSCLC patients. TLR max can sensitively predict OLM preoperatively in patients with NSCLC.

ObjectiveTo explore the best treatment method of cerebral artery dissection.Methods This study included eight patients who were definitely diagnosed as cerebral artery dissection by the cerebral angiography in our department of neurology during Oct.2009 and Nov.2011.They were all treated by the anticoagulation or anti-platelet methods.Some patients received the stent therapy.All patients' were followed for at least three months. The treatment effect was assessed by NIHSS,mRS and by the cerebral angiography.ResultsSix patients had carotid artery dissection,2 had vertebral artery dissection.Four patients were given anticoagulant therapy and the other 4 were given anti-platelet therapy. The reexamination by angiography 10-14 days after admission showed that in 3 patients,the stenosis was aggravated or the infarction occurred.They were diagnosed as having repeated transient ischemic attack (TIA) during pharmacotherapy and received stents for treatment.There was no TIA and cerebral infarction in the follow-up period after individualized therapy.Mean NIHSS scores of 8 patients between pre and post treatment were 5.9,1.6 respectively. Mean mRS scores pre and post treatment were 2.5,0.9respectively.Conclusion The treatment for patients with cerebral artery dissection should be individuated.The patients in acute stage should get anticoagulation,anti-platelet therapy and angiography re-examination.According to the clinical manifestation and cerebral angiography,the next step for the treatment should be done.
