Learners' autonomous learning serves as the target of the second and foreign language teaching.It is also a key factor showing whether the reform of the college English teaching in our country will succeed or fail.The particular English language teaching environment in China is far from being ideal in comparison with the second or even foreign language teaching environment in the Western Countries.The paper makes an analysis on certain factors relating autonomous learning in the English language teaching environment in China and a discussion on how to develop and promote the Chinese English language learners' autonomous learning.

Long non-coding RNA was initially identified as "noises" of gene transcriptions. However, with the developing researches of ENCODE, it was found that the long non-coding RNAs can regulate the genomic expressions in the form of RNAs in epigenetic, transcription, and post transcriptional levels, which is involved in the regulation of diverse cellular processes and has significant influences on occurrence and precaution of human diseases. This paper introduces functions and features of the long non-coding RNAs, and sums up the internal relation between long non-coding RNAs, diabetes and diabetic complications on the basis of existing researches. These advances can provide the basis for the further understanding of molecular medicine on occurrence and evolution of diabetes.

Objective To explore the efficacy and safety of large and conventional fractionated three dimensional conformal radiation therapy for non small cell lung cancer with superior vena cava compression syndrome, and to provide clinical reference for improving the prognosis of patients with non small cell lung cancer. Methods The general data of 63 patients with non small cell lung cancer complicated with superior vena cava syndrome treated in Lu'an Hospital of Traditional Chinese Medicine from January 2010 to December 2012 were analyzed retrospectively. According to the different treatment methods, the patients were divided into observation group ( n =28) and control group ( n =35) .The control group was given conventional fractionated three-dimensional conformal radiation therapy, three dimensional conformal radiation therapy was given to the observation group. The clinical efficacy, toxicity, and 1, 2 years survival rate of the two groups were compared. Results The complete remission rate of observation group was 96.43%, which was significantly higher than 74.29%in the control group (P<0.05) . The complete remission in the observation group was 89.29%in two weeks, which was significantly higher than 62.86%in the control group (P<0.05) . The total effective rate of observation group was 85.71%, which was significantly higher than that 62.86%in the control group (P<0.05) . The clinical benefit rate of observation group was 96.43%, and there was no significant difference between the two groups (P>0.05) . There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05) . There was no significant difference in 1, 2 year survival rate between the two groups (P>0.05) . Conclusion Three dimensional conformal radiation therapy for non small cell lung cancer patients with superior vena cava syndrome is superior to conventional treatment, and does not increase the toxic side effects, which is worthy of clinical attention.

AIM: The changes of myocardial nuclear membrane Ca 2+ -ATPase function was investigated in ischemia/reperfusion injury. METHODS: The model of myocardial ischemia/reperfusion injury was established in rats. Myocardial nuclei were purified with sucrose density centrifugation,the activity of Ca 2+ -ATPase was measured and calcium uptake was assayed with [ 45 Ca 2+ ] . RESULTS: Plasma levels of malondialdehyde (MDA) and free fatty acid (FFA) in myocardial ischemia/reperfusion injury increased significantly( P

Purpose To investigate the expression of muscarinic cholinergic receptor 3 (M3R) in small cell lung cancer (SCLC) and the correlation between it and clinical characteristics of SCLC. Methods The M3R expression was examined in 60 SCLC patients ad-mitted using immunohistochemistry. The patients were evaluated by clinical history, physical examination and chest CT. Survival time was got through telephone follow-up. Results The M3R expression in primary SCLC tissues was higher than that in normal lung tis-sues. The M3R expression had no difference between limited-disease and extensive-disease of SCLC. There was no correlation between M3R expression and age, gender, lymph node metastasis. The M3R expression was significantly correlated with smoking history. The survival time of M3R negative patients was longer than that of M3R positive patients in Kaplan-Meier survival curve. Conclusion The M3R expression in primary SCLC tissues was higher than that in normal lung tissues. M3R expression had some correlation with prog-nosis of SCLC patients.

Objective To observe the anti-cancer effect in vitro of Aitongxiao Granules containing serum on SMMC-7721 and Bel-7404 liver cancer cells, thus revealing the anti-cancer mechanism of the treatment in adjusting proliferation and apoptosis. Methods Male Sprague-Dawley rats were administered by gastrogavage Aitongxiao decoction of 86.4, 43.2, 21.6 g/kg twice a day for 1 week. Using serum pharmacologic method, the proliferation of SMMC-7721 and Bel-7404 liver cancer cells were determined by MTT chromatometry after co-cultured with medicated serum containing different concentration of Aitongxiao decoction. The apoptosis of SMMC-7721 and Bel-7404 liver cancer cells were detected by flow cytometry. Results The research in vitro showed that Aitongxiao Granules containing serum low, medium and high dose groups had varying degrees of inhibition on hepatoma cells, and this inhibition showed a concentration dependence within a certain range. Aitongxiao Granules containing serum could induce apoptosis of human hepatoma SMMC-7721 cells and Bel-7404 cells. Conclusion Aitongxiao Granules showed effect of inhibiting proliferation and inducing apoptosis on SMMC-7721 and Bel-7404 cells in vitro.

Objective To study the regulatory effects of Ca 2+ , ATP, ADP and AMP on myocardial nuclear Ca 2+ ATPase activity after ischemia reperfusion injury Methods The model of myocardial ischemia reperfusion injury was established in rats Myocardial nuclei were purified using sucrose density gradient centrifugation The activity of Ca 2+ ATPase was measured with ascertaining phosphate Results Compared with the control, plasma levels of MDA and FFA after myocardial ischemia reperfusion injury increased significantly ( P

Objective: To explore the effects of rhPRL on the cytotoxicity and proliferation of natural killer cell lines. Methods: Cytotoxici-ty and proliferation analysis were done by MTT,RT-PCR method,direct immunofluoresence technique and FAGS protocol was applied to detect the PRL-R and CD25 expression on NK cell lines. Results: MTT results indicated that PRL play a significant roles on the proliferation and cytotoxicity of IL-2 dependent cell lines NKL and NK-92 in the presence of trace amounts of IL-2. In contrast, PRL did not significantly alter the proliferation and cytolyric activity of YT. RT-PCR and FACS analysis showed three NK cell lines expressed PRL-R and CD25 differently, stimulation of rhPRL could upregulate CD25 and IL-2 expression. Conclusion: rhPRL could augument the proliferation and cytotoxicity of NK cell partly by upreglating of IL-2. Ra chain(CD25) and interaction with IL-2 signal transduction.

Objective To explore the correlative factors of mental disorder in patients with head injury. Methods 255 subjects sustained with head injury and survived from traffic accident in Chengdu were assessed with Structured Clinical Interview for DSM-Ⅳ axis Ⅰ disorders (SCID-I/P) , Personality Disorder Questionaire for CCMD-2-R(PDQC), Structured Clinical Interview for CCMD-2-R(SCICP), WAIS-RC, WMS, brain electric activity mapping (BEAM) after completion of clinical management. Based on the diagnostic criteria of organic mental disorder in CCMD-3, mental disorders in 255 subjects were diagnosed. Results The incidence of mental disorders in the patients with head injury was 72.5% (185/255). Mental disorders in patients with head injury were correlated with educational level, type and severity of the head injury, or injuries involving the left frontal lobe injury, the left temporal lobe or multiple lobes and BEAM abnormality. Conclusion The incidence of mental disorder is high in the patients with head injury. Educational level, type and severity of the head injury, the location of the injured brain, injury involving multiple lobes of the brain may affect morbidity of mental disorders in patients with head injury.
