BACKGROUND:Previous studies have demonstrated that amblyopic patients have a variety of dysopsia compared with normal people.Engineered visual system could find amblyopia through detection of human visual system.OBJECTIVE:To screen sensitive indexes for amblyopia through visual function examination to establish a intemet-based amblyopia screening method.DESIGN,TIME AND SETTING:Randomized,blinded,and controlled experiment.The study was performed at Department of Optometry,People's Hospital of Guangxi Zhuang Autonomous Region from September to November 2008.PARTICIPANTS:A total of 80 volunteers undergoing visual examination in Department of Optometry,People's Hospital of Guangxi Zhuang Autonomous Region were selected,aged 4-19 years.All people had no organic diseases of eyes.They were divided into normal group (n=40) and ambiyopic group (n=40) according to their corrected visual acuity (whether ＞ 4.9).METHODS:Using vision system,the various visual function indexes of each participant were examined.The data from single eye and both eyes were collected and analyzed using Fisher.The sensitive indexes were selected to establish identification function for amblyopia screening.MAIN OUTCOME MEASURES:Age,visual noise,orientation identification and contour integration of participants were examined.RESULTS:Results showed that age,visual noise,orientation identification and contour integration were clinically significant indexes,and cross validation suggested that the identification correct rate was 92.5%.The discriminant function of amblyopia was Y1=1.175X1+0.786X2+0.928X3+1.061X4-0.225X5+2.547X6+1.313X7-18.651;the discdminant function of normal vision was Y2=1.369X1+ 1.728X2+1.779X3+1.549X4-1.912X5+2.665X6+0.387X7 26.640.CONCLUSION:Visual noise,orientation identification and contour integration in vision detection system could be used to screen amblyopia in children,in particular with assistance of internat.

Over-expression of CD151 was found to be associated with metastasis and poor prognosis of prostatic carcinoma. This study was designed to examine the mechanism by which CD151 promotes the proliferation and migration of prostatic cancer cells. The pAAV-CD151, pAAV-GFP and pAAV-CD151-AAA mutant plasmids were constructed and used to transiently transfect PC3 cells (a prostatic carcinoma 3 cell line) by the mediation of Fugene HD. Then, the cells were assigned to control group, pAAV-GFP group, pAAV-CD151 group, and pAAV-CD151-AAA group respectively. Cell proliferation was evaluated by using the 3-[4,5-dimet-hylthiazol-2-yl]-2,5, diphenyltetrazolium bromide (MTT) method. Cell migration assay was performed by using Boyden chambers. The formation of CD151-integrin α3/α6 complex was determined by the method of co-immunoprecipitation. The protein expression levels of CD151 and extracellular signal-regulated kinase (ERK) were measured by Western blotting. The results showed that transfection of pAAV-CD151 or pAAV-CD151-AAA mutant increased the expression of CD151 protein in PC3 cells. Co-immunoprecipitation showed that more CD151-integrin α3/α6 complex was formed in the pAAV-CD151 group than in the control group, the pAAV-GFP group and the pAAV-CD151-AAA mutant group. Furthermore, the proliferative and migrating capacity of PC3 cells was substantially increased in the pAAV-CD151 group but inhibited in the pAAV-CD151-AAA mutant group. CD151 transfection increased the expression of phospho-ERK. Taken together, it was concluded that CD151 promotes the proliferation and migration of PC3 cells through the formation of CD151-integrin complex and the activation of phosphorylated ERK.

Objective: To analyze the relationship between inflammatory factors and relevant risk factors in patients of essential hypertension (EH) combining acute coronary syndrome (ACS) with its clinical significance. Methods: Our research included 3 groups: EH group, n=79 patients with standard criteria, EH+ACS group, n=85 and Control group, n=48 normal subjects. Blood levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), tryptase (TPS) and relevant clinical, biochemical parameters were measured; risk factors for cardiovascular disease were examined and the relationship between above parameters, risk factors and ACS occurrence in EH patients was studied by Logistic regression analysis. Results: The OR values were all greater than 1 in fibrinogen (Fbg), high-sensitivity C-reactive protein (hs-CRP), TPS, atherosclerotic plaque, Lp-PLA2 and EH grading. Fbg was the most significant independent risk factor (OR=22.242, 95% CI 6.458-76.609, P<0.0001), the standardized partial regression coefficient b'as absolute value (b') was 1.079 which was the highestone in above 6 variables with the strongest impact for ACS occurrence in EH patients. Conclusion: Fbg, hs-CRP, TPS, atherosclerotic plaque and EH grading were the independent risk factors for ACS occurrence in EH patients; Fbg was the highest risk factor for ACS occurrence with the strongest impact, which provided a new direction for ACS prevention and treatment.

Purpose: Lymphoblastic lymphoma (LBL) is an invasive neoplasm of precursor T-cell or B-cell lineage.A broadly accepted standard treatment for adult LBL has not yet been defined. Materials and Methods: To address this issue, we compared two chemotherapy regimens: a modified non-Hodgkinlymphoma Berlin–Frankfurt–Mu!nster-95 (NHL-BFM-95) regimen and HyperCVAD/MA. Thisretrospective study consecutively enrolled 207 adult LBL patients at two hospitals from2000 to 2018. Univariate and multivariate analysis were used to assess prognostic factors. Results: In the present study, most clinical characteristics were similar between the two treatmentgroups except for age and lactate dehydrogenase (LDH) level. Patients treated with modifiedNHL-BFM-95 regimen tended to be younger and with elevated LDH level. The modified NHLBFM-95 regimen produced better treatment outcomes than those with HyperCVAD/MA inpatients with T-LBL or patients < 40 years. Treatment with HyperCVAD/MA, high EasternCooperative Oncology Group scores, and bone marrow involvement were independent riskfactors in T-LBL. No patients interrupted treatment for severe adverse events. Conclusion The results suggested that the modified regimen is well-tolerated and can produce the promisingoutcomes in patients with T-LBL or patients < 40 years.
