Progress in Modern Biomedicine.2017;17(26):5022-5028. doi:10.13241/j.cnki.pmb.2017.26.005

Objective:we aim to determine the relationship between Cell sarcoma (c-Src) expression in patients with EOC and the disease phenotype.Methods:c-Src expression was evaluated using Western blotting analysis in 21 ovarian carcinomas and 4 normal ovarian tissues.Immunohistochemistry was used to evaluate c-Src expression in 134 ovarian carcinomas and 26 normal ovarian tissues.The association between c-Src expression and clinically pathologic characteristics were also assessed in these patients.Results:Our results indicated elevated c-Src protein in EOCs compared with that in normal tissues.The overexpression of c-Src was significantly associated with aggressive features,such as advanced disease stage,poor histological grade,lymph node metastasis,and tumor recurrence (P＜0.05).In addition,the overexpression ofc-Src is significantly associated with EOCs' prognosis.Conclusion:c-Src overexpression was significantly associated with the malignant biological behavior of tumor,suggesting c-Src as a potential preventive target in these patients.

Progress in Modern Biomedicine.2017;17(22):4397-4400. doi:10.13241/j.cnki.pmb.2017.22.048

Posterior reversible encephalopathy syndrome is a clinical imaging syndrome associated with multiple pathogenic factors.The main clinical manifestations were headache,seizures,psychotic symptoms,visual disturbance,disturbance of consciousness,etc.The parieto-occipital reversible white matter lesions are the main manifestations of the imaging.If this disease can be diagnosed and treated in time,the clinical symptoms and imaging changes of most patients can be disappeared.If the diagnosis and treatment cannot be obtained in time,it may happen some irreversible damage,serious and even life-threatening,so it is very important to strengthen the understanding,diagnosis and treatment of this disease.At present,the pathogenesis of the disease is still not clear,now reviewed its pathogenesis and imaging manifestation in order to strengthen the clinician's understanding of the disease's pathophysiological mechanism and improve the level of diagnosis.

Progress in Modern Biomedicine.2017;17(22):4394-4396,4400. doi:10.13241/j.cnki.pmb.2017.22.047

Acute promyelocytic leukemia (APL) was considered to be the most rapidly fatal leukemia,because of serve clinical manifestation,high rate of early death and the low cure rate.APL has achieved great success due to the application of ATRA and ATO.Although the complete remission rate is about 90％,the relapse rate has been reported to be as high as 15％-30％.So reducing the recurrence and improving long-time survival have become the focus of the study.Choosing the reasonable treatment after remission is very important.The post remission therapy usually include consolidation therapy and maintenance therapy,but the optimal strategy has been controversy.Therefore,this artical will review the literature of APL in consolidation therapy.

Progress in Modern Biomedicine.2017;17(22):4376-4381. doi:10.13241/j.cnki.pmb.2017.22.043

Objective:The significant role of long non-coding RNAs (lncRNAs) in early diagnosis and predicting prognosis has been recognized in various cancers recently.However,the prognostic value of HOXA transcript at the distal tip (HOTTIP),a vital lncRNA in tumorigenesis,remains unclear.In this study,we evaluated its prognostic value by analyzing the correlation of HOTTIP expression with overall survival (OS),lymph node metastasis (LNM) and distant metastasis (DM) in different cancer types by meta-analysis.Methods:We performed a systematic search in PUBMED,MEDLINE,Web of Science and Cochrane Library update to November of 2016.A total of 604 patients from 6 studies were included in final analysis and went through a quantitative meta-analysis by Review manager 5.3.Results:We demonstrated that high expression of HOTTIP had a significant correlation with poor OS (hazard ratio [HR] =2.37,95％ confidence interval [CI] =1.81-3.10,p＜0.001),high LNM rate (odds ratio [OR]=2.29,95％CI=1.54-3.40,p＜0.001) as well as more DM occurrence (OR=3.30,95％CI=1.78-6.12,p＜0.001).Conclusion:Our results indicated that long non-coding RNA HOTTIP may serve as a potential prognostic biomarker in cancer progression.

Progress in Modern Biomedicine.2017;17(22):4372-4375,4333. doi:10.13241/j.cnki.pmb.2017.22.042

Objective:To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on cognitive function in patients with chronic schizophrenia.Methods:100 cases patients with chronic schizophrenia weree selected.They were divided into rTMS stimulation group and pseudo stimulation group according to the random number table method,and each group include 50 cases.The positive and Negative Syndrome Scale (PANSS) and the Treatment Emergent Symptom scale (TESS) were used to assess the clinical symptoms and side effects before and after the treatment;The Wisconsin Card Sorting Test (WCST) and Repeatable Neuropsychological State Measurement (RBANS) were used to assess the patients' cognitive function before and after treatment.Results:After treatment,the PANSS total score,the positive subscale score,the negative subscale score,the general psychopathological subscale score in the rTMS stimulation group were significantly reducing (P＜0.05),and significantly lower than those in the pseudo stimulation group (P＜0.05),but the TESS scores between the two groups did not differ significantly before and after treatment.The percentage of WCST in rTMS stimulation group was significantly higher than that in the pseudo stimulation group (P＜0.05),and the total time and wrong thinking time was shorter than that in the pseudo stimulation group (P＜0.05);The visual span and delayed memory performance of RBANS was significantly increased in the rTMS stimulation group (P＜0.05),and the visual span was significantly higher than that in the pseudo stimulus group (P＜0.05);There were 2 cases of patients with mild symptoms after the first treatment in RTMS stimulation group,all patients were without complaint followed up for 3 months.Conclusion:rTMS treatment on the part of the cognitive function of patients with chronic schizophrenia has a certain improvement effect,and higher security,it is worth further study.

Progress in Modern Biomedicine.2017;17(22):4361-4364. doi:10.13241/j.cnki.pmb.2017.22.039

Objective:To explore the expression of N-cadherin and its correlations with the clinicopathological features of human ovarian carcinoma.Methods:The expression of N-cadherin in 281 cases of ovarian carcinoma tissues were determined by immunohistochemical method.The correlations of N-cadherin expression with the clinicopathological features of human ovarian carcinoma were analyzed.Results:There was higher expression of N-cadherin in the metastatic lesions than its paired primary lesions (P =0.018).The expression level of N-cadherin in ovarian carcinoma was correlated with the FIGO stage (P =0.034),histological type (P ＜0.001) and tumor grade (P =0.004).Conclusions:High expression of N-cadherin might positively correlate with the invasion and migration ability of ovarian carcinoma cells,which was more common in the the advanced (FIGO Ⅱ-Ⅳ) ovarian carcinoma,high-grade serous carcinoma,and high grade ovarian carcinoma.N-cadherin might be useful in estimating the biological behavior of human ovarian carcinoma.
