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.

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.

Objective To investigate the clinical efficacy of pre-hospital mild hypothermia in patients with severe craniocerebral injury,and to explore the possible mechanism by the changes of serum Malondialdehyde (MDA).Methods 120 cases of severe craniocerebral injury were divided into pre-hospital mild hypothermia group (group A,65 cases) and control group(group B,55 cases) by random number table.Patients in group A were gave pre-hospital mild hypothermia treatment,and patients in group B were gave mild hypothermia therapy only after hospitalization.Comparison of the change of serum MDA at admission,the 7th and 14th day between two groups,and the functional outcomes were evaluated by GOS score in 6 months after treatment.Results The MDA levels of two group at seventh days and 14 days were higher than that at admission [(10.4 ± 1.5)nmol/L and (8.2 ± 1.2)nmol/L in group A,(12.6 ± 1.9)nmol/L and (10.0 ± 1.4)nmol/L in group B,P ＜0.05],and it was the highest at 7th day,and its in group A was significantly lower than that in group B at 7th,14th day [(6.9 ± 1.1) nmol/L in group A,(6.6 ±1.0) nmol/L in group B,P ＜ 0.05].The good prognosis rate was 47.7％ (31 cases) in group A,higher than the 38.2％ (21 cases) in group B;The mortality rate was 12.1％ (8 cases) in group A,lower than the 21.4％ (12 cases)the group B,and the difference was statistically significant (Z =-2.132,P ＜ 0.05).Conclusion Pre-hospital mild hypothermia treatment can improve the prognosis of patients with severe craniocerebral injury and alleviate the damage of brain tissues.

Objective To study the effect of millimeter wave radiation on human hepatoma cell. Methods BEL7404 hepatoma cells were cultured in vitro and randomly divided into 4 groups: the control group, the group radiated by millimeter wave for 30 min, the group treated with Fluorouracil(5 FU), and the group radiated by millimeter wave and treated with 5 FU simultaneously at same time. The ability of 35.8 GHz millimeter wave to induce the apoptosis of hepatoma cell was evaluated by analyses of fluorescence microscopy, DNA fragmentation assay and flow cytometry assay. Results BEL7404 cells radiated by the millimeter wave had the typical characteristics of apoptosis. Comparaed with the control group [(3.21? 1.06)%], the apoptosis rates were higher in 30 min radiating or/and 5 FU groups[ (14.33? 2.66)%, (18.58? 2.57)%, (27.91? 3.66)%]. Poly adp ribose polymerase(PARP) was found to be cleavaged in all the cells in millmeter wave radiation or/and 5 FU groups. Conclusion Radiation of 35.8 GHz could induce apoptosis of BEL7404 cell in vitro, and could act synergistcally with 5 FU treatment.

Objective To report the preliminary clinical results of treatment of severely comminuted radial head fractures by replacement with floating cup radial head prosthesis. Methods In the period from August 2002 to June 2005, replacement with floating cup radial head prosthesis was performed to treat 10 cases of Mason Ⅲ , Ⅳ radial head fractures, of whom 9 were acute fractures and 1 old. Results All the patients were followed up for 6 to 40 months (mean 14.9 months). The mean flexion/extension of the elbow was 133.5? /9.0? , while the mean pronation/supination of the forearm was 78.5? /84.0? . There were 3 cases of mild pain, 1 case of mild valgus instability in the elbow and 3 cases of mild weakness. The Broberg and Morrey elbow scores averaged 93. The result was excellent in 6 cases, good in 3 and fair in 1, the excellent and good rates were 90% . Conclusion The replacement with floating cup prosthesis shows satisfying preliminary clinical outcome in the treatment of radial head fractures unable to be reduced, while its long- term result needs further follow- up

Background Studies showed that microRNA (miR)-375 suppresses the growth,apoptosis,migration and adhesion of tumor cells,and it plays a regulation to the changes of vascular endothelial growth factor (VEGF) in tumor tissue to arrest neovascularization.However,whether miR-375 intervenes the formation of new blood vessel in eyes is unelucidated.Objective This study was to explore the effects of miR-375 on human retinal capillary endothelial cells (HRCECs) function induced by hypoxia.Methods HRCECs were cultured using IMDM and divided into normal control group,CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2 +miR-375 mimic control group,CoCl2+miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group,and hypoxia cell models were created by adding 200 μmol/L CoCl2.MiR-375 and frizzled 4 (FZD4) small interfering RNA (siRNA) were transfected into the cells by 50 nmol/L miRNA lipidosome for 48 hours.The proliferation of the cells was detected by MTT assay;migrated number of the cells was examined by Transwell chamber assay;ELISA was employed to detect the concentrations of VEGF and VE-cadherin in the medium;the expression of β-catenin,cyclinD1,matrix metalloproteinase-2 (MMP2) and VEGF proteins were analyzed by Western blot;tube length of vessel formation was evaluated by Matrigel assay.Cultured cells were divided into normal control group,CoCl2 model group,CoCl2 +mock group and CoCl2 + FZD4 siRNA group,the relative expression of FZD4,a miR-375 targeted gene,was detected by luciferase reporter.Results The relative expression of miR-375 mRNA was significantly increased in the CoCl2 +miR-375 mimic group compared with the CoCl2 + miR-375 mimic control group and reduced in the CoCo2 + miR-375 inhibitor group compared with the CoCo2 + miR-375 inhibitor control group (t =-19.237,8.764,both at P＜0.01),with a higher transfected efficacy for miR-375.The cell proliferative fold,migrated cell number,VEGF and VE-Cadherin contents in the medium and the tube length were significantly different among the CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2 +miR-375 mimic control group,CoCl2 +miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group (F =24.324,26.776,14.113,19.225,15.040,all at P＜0.001),and those in the CoCl2 +miR-375 mimic group were evidently reduced in the CoCl2 +miR-375 mimic group compared with the CoCl2 +miR-375 mimic control group,while those in the CoCl2 +miR-375 inhibitor group were considerably elevated in comparison with the CoCl2 +miR-375 inhibitor control group (all at P＜0.01).The expressions of β3-catenin,cyclinD1,MMP2 and VEGF protein were significantly different among the normal control group,CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2+miR-375 mimic control group,CoCl2 +miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group (F=11.753,13.283,16.770,10.334,all at P＜0.001).In addition,the cell proliferative fold,migrated cell number and the tube length were significantly increased in the CoCl2 model group and CoCl2+mock group,and those in the CoCl2+FZD4 siRNA group were decreased in comparison with the CoCl2 +mock group (all at P＜0.05).Conclusions MiR-375 inhibits the growth,migration and tube formation ability of HRCECs in hypoxic status probably by regulating the activation of Wnt pathway via directly targeting FZD4.
