Epigenetics consists of DNA methylation,post-translational modification of histon,microRNA and long non-coding RNA,which regulate angiogenesis by acting on different targets.Epigenetics has become potential targets of anti-angiogenesis in tumor.

Recently,studies have demonstrated that several signaling pathways including Wnt,Notch,and Hedgehog which are involved in the regulation of the stem cells are abnormally activated in lung cancer.They are closely associated with some properties of the lung cancer stem cells,such as high tumorigenic,high metastasis,drug resistance and so on.In addition,several studies have shown that the population of the lung cancer stem cells,which are resistant to radiotherapy and chemotherapy significantly,highly express drug resistance proteins.Therefore,how to target lung cancer stem cells and ultimately cure the disease is becoming a hotspot in the cancer targeted therapy.

Objective: To evaluate the clinical effect of individualized enteral nutritional (EN) support in severe stroke patients.Methods: Totally 120 severe stroke patients with nutritional risk were divided into two groups according to single or double admission number.The 60 patients in the intervention group received an individualized EN with different formula and concentrations according to the clinical status,and supplemented trace elements as occasion required.In the routine group, the patients received EN with standard formula.The energy supply was 83-125 kJ· kg-1·d-1 in both groups.Blood albumin(Alb), pre-albumin(PA), hemoglobin(Hb) and vitamin C(VC) were examined before and after the 21-day nutritional support.The lung infection and gastrointestinal (GI) complications were observed, and the hospital stay and cost were recorded as well.Results: After 21 day''s nutrition support, the serum levels of Alb, PA and VC in the intervention group were not statisticly significant than before (P＞0.05), and the serum levels of Alb, PA and VC were significantly higher than those in the routine group(P＜0.05).The incidence of complications in the in the intervention group was lower than that in the routine group (P＜0.05), and the length of hospital stay and hospitalization was shorter than that in the routine group (P＜0.05).Conclusion: Individualized enteral nutritional support can significantly improve nutritional status, reduce inflammation reactions and GI complications in severe stroke patients, which is worthy of clinical use.

Chimeric antigen receptor T cells (CAR-T) therapy is progressing rapidly, and its safety has been widely concerned. At the 62nd American Society of Hematology Annual Meeting, a series of reports on the mechanism, predictive indicators and treatment strategies of major adverse reactions were carried out. These reports have certain guiding significance for comprehensively improving the safety of CAR-T therapy.

Objective　To investigate the significances of telomerase activity and P53 expression in Non-small cell lung cancer (NSCLC). Methods　The activity of telomerase in cancerous tissues was detected by PCR-ELISA, and the expression of P53 protein was detected by S-P method. Results　The telomerase activity and P53 expression were significantly higher in NSCLC tissues than in normal lung tissues. The telomerase activity and P53 expression had close association with the differentiation of cancer cells and lymph node metastasis. Conclusion　It is very valuable to measure telomerase activity and P53 expression in studying the initiation and progression of NSCLC.

Objective To investigate the symptom characteristis as well as the clinical assessment methods of dysphagia and oral motor function in children with cerebral palsy(CP).Methods A total of 116 children with CP,aged 18 months to 96 months(66 boys and 50 girls),treated in Qingdao Rehabilitation Center for Disabled Children from June 2009 to September 2010,were included in the study.Diagnosis and subtype of CP were determined by neuropaediatrician,the dysphagia disorders survey(DDS)as well as oral motor assessment were conducted by the speech therapists.Results Of the 116 cases,22.4％ of the cases were with mild dysphagia and 34.5％ with moderate to severe dysphagia,resulting in a prevalence of dysphagia of 56.9％.The main problems of these cases occurred during oral phase and pharyngeal phase,including inadequate feeding skills(involving sucking,biting,chewing or/and swallowing),coughing,vomiting and choking during feeding,cry/overextension of neck and head during feeding,drooling,hypertonic tongue and inadequate tongue lateralization.The severe dysphagia was encountered frequently in children with spastic quadriplegic,dyskinetic or mixed type CP children.Of the 116 cases,90 cases(77.59％)were with oral motor dysfunction(including all spastic quadriplegic,dyskinetic or mixed type children).The oral motor scores of CP children were significantly lower than those of the controls(P ＜ 0.01).Conclusions Oral phase dysphagia and oral motor disorder might be considered as the common clinical problems among the patients with CP,and could be assessed by using DDS combined with oral motor assessment,but for dysphagia during pharyngeal or esophagus phase,the videofluoroscopic modified barium swallow should be used for further evaluation.

Objective To explore the protection for ischemic myocardium with warm-up phenomenon and KATP channel blocker interventional effect on it. Methods Patients with chronic stable angina who came into the study were divided into three groups according to the presence of diabetes and its treatment ways: 25 patients without diabetes came into a NDM group, 22 patients with diabetes treated with glibenclamide came into a DMG group and 25 patients with diabetes but on diet only came into a DMD group. All the patients underwent sequential bicycle ergnmeter exercise test twice (EX1, EX2)with a time interval of 15 min. Parameters including exercise duration (ED), time for 1 mm ST-segment depression (T-STD), maximum STD (mm) and corresponding heart-rate systolic blood pressure product (RPP) were observed respectively. The parameters obtained during EX2 were compared with those obtained during EX1.Results In the group NDM,ED and T-STD were prolonged [(546. 04±103.78)s vs (617.52±106. 96) s, P < 0.05 and (378.64±92.34)s vs (436.84±91.25)s, P<0.05], STDmax was shortened [(2.06± 0.37) mm vs(1.75±0.41)mm,P<0.01]and RPP was increased[(173.77±34.73) beats±min~(-1)·nun Hg~(-2) vs (199.23±37.07 beats·min~(-1)·mm Hg~(-2), p<0.05]as the parameters during EX2 were compared with those during EX1. In the group DMG, there was no difference in these analysed parameters except that T-STD was prolonged [(328.45±64.66)s vs (363.00±81.48)s, P<0.01]when these of EX2 and EX1 were compared. In the group DMD,all the analysed parameters improved significantly during the second test (EX2) in comparison with the first test (EX1) as the results in the group NDM. Conclusions Exercise test can induce warm-up phenomenon in patients with chronic stable angina poctoris.The KATP channel blocker glibenclamide can block the warm-up phenomenon.
