Objective To study the mechanism of miR-21 in regulating the invasion of human glioblastoma (GBM) cells in vitro. Methods The transfection reagent oligofectamine was mixed with antisense miRNA-21 (AS-miR-21) and nonsense oligodeoxyribonucleotides (ODN), respectively, and then, they were added into the medium of U251 GBM cell line as AS-miR-21 treatment group and nonsense ODN treatment group, respectively; control group (treated with PBS) was also established.MiR-21 luciferase reporter assay was used to detect the miR-21 knocking down effect. Matrigel cell growth assay and Transwell assay were used to determine the invasion and migration abilities of U251 cells. Western blotting was employed to test the expressions of invasion-related proteins (FAK,MMP-9/2, TIMP-1 and Tubulin-α); immunofluorescence was also employed to observe the morphology of Tubulin-α protein in GBM cells. Results Luciferase intensity in as-miR-21 treated U251 cells was significantly suppressed as compared with that in the control group and nonsense ODN treatment group (P<0.05). The diameter of cultured clone in as-miR-21 treated U251 cells was smaller than that in the controls and nonsense ODN treatment group (F=102.819, P=0.000). Decreased cells via the transwell member in thc AS-miR-21 treatment group were detected as compared with those in the controls and cnonsensc ODN treatment group (F=243.465, P=0.000). The expressions of FAK, MMP-2/9 weredown-regulated and that of TIMP-1 was up-regulated in the AS-miR-21 treated tumor cells as compared with the other 2 groups (P<0.05). No obvious changes were noted on the expression of Tubulin α,however, the morphology of Tubulin α protein in the AS-miR-21 treatment group changed. Conclusion High expression of miR-21 induce the ability of U251 GBM cell invasion and miR-21 can be taken as a candidate for gene therapy of human glioma.

OBJECTIVETo study the anti-invasion effect of SEPT7 gene on U251MG glioma cells and its possible molecular mechanism.
METHODSRecombinant adenovirus vector carrying SEPT7 gene (rAd5-SEPT7) was transduced to human glioma cell line U251MG, and empty adenovirus vector was used as control. Tumor invasion was examined by Transwell method and 3 D-Matrigel assay, and tumor cell migration by wound-healing method and 2 D-Matrigel assay. Three major molecular events associated with cell motility and migration, including changes of expression in MMP2, MMP9, MT1-MMP, TIMP1 and TIMP2, the alteration of integrin alpha(v)beta(3) expression, and the structural change of cytoskeleton protein, tubulin-alpha, in U251 cells transduced with rAd5-SEPT7 were studied by Western blotting, immunofluorescence and laser scanning confocal microscope, respectively.
RESULTSThe invasive and migratory capabilities of cells transduced with rAd5-SEPT7 were inhibited. The expression of extracellular matrix metalloproteinases MMP-2, MMP-9, MT1-MMP and integrin alpha(v)beta(3) was significantly decreased, while the expression of matrix metalloproteinase inhibitor TIMP1, TIMP2 was upregulated. Intracellular cytoskeleton protein-tubulin-alpha in U251 cells exhibited prominent morphological changes which including the appearance of distortion and aggregation resulting from redistribution of tubulin-alpha, and this feature of alteration was similar to the tubulin-alpha structure in normal non-tumor cells.
CONCLUSIONSEPT7 gene can inhibit the invasion and migration ability of U251 glioma cells. Its molecular mechanism may include that SEPT7 gene reverses the imbalanced state of MMPs/TIMPs, downregulates the expression of integrin alpha(v)beta(3) and alters the structure of tubulin-alpha of U251MG glioma cells. It is suggested that SEPT7 gene could be a good candidate for gene therapy of gliomas.

OBJECTIVETo detect the differential expression of Notch1 and Notch2 in human astrocytoma and medulloblastoma; and to study the role of Notch1 and Notch2 in the development of both tumors.
METHODSImmunohistochemical staining (SP method) and Western blot analysis were used to detect Notch1 and Notch2 expression in tissue arrays and freshly resected samples of normal brain tissue, astrocytoma and medulloblastoma.
RESULTSNotch1 and Notch2 were negative in normal human brain tissue. Notch1 was highly expressed (total positive rate 80.0%, 48/60) while Notch2 was not detected in grade IV astrocytomas and sporadically observed in lower grade astrocytomas (total positive rate 10.0%, 6/60). The percentage of positive tumor cells and expression level of Notch1 increased with higher histologic grade (r = 0.859, P < 0.05). On the other hand, overexpression of Notch2 was detected in medulloblastoma (9/10) in contrast with lower expression of Notch1 (2/10).
CONCLUSIONSNotch1 and Notch2 show differential expression in astrocytoma and medulloblastoma. This may be related to their different functional activities during the process of brain development.

OBJECTIVETo evaluate the impact of Jinlongshe Granule (, JLSG) on quality of life (QOL) of stage IV gastric cancer patients.
METHODSThis randomized, double-blind and placebo-controlled clinical trial included 50 patients with advanced gastric cancer. They were equally randomized into a JLSG group and a placebo group. Patients in both groups received routine Chinese herbal decoctions according to Chinese medicine (CM) treatment based on syndrome differentiation. Patients in JLSG group received additional JLSG, and those in the placebo group received an additional placebo. In the JLSG group, 19 patients who completed the study were used for analysis. In the placebo group, finally the data of 20 patients who completed the study were used for analysis. The treatment course was at least 3 months, and the follow-up duration was at least 6 months in 5 interviews. Repeated measurements of the subscale items and individual items in European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire C30 (EORTC QLQ-C30) obtained at the 5 interviews were compared using different patient groups, changes over time and changes within one group over time independently to observe the tendency of changes in the scores.
RESULTSUsing time as the variant, there was signifificant difference in 4 functional scales (physical, role, emotional and social, P<0.05), 3 symptom scales (fatigue, nausea and vomiting and pain,P<0.05) and a global health status/QOL scale (P<0.05) and 6 single symptoms dyspnoea (P>0.05), insomnia (P<0.05), appetite loss (P<0.05), constipation (P<0.05), diarrhea (P>0.05) and financial difficulties (P<0.05). There was also signifificant difference in these items between the two groups when the placebo group and group over time were used as variants (P<0.05 or P<0.01).
CONCLUSIONAdditional use of JLSG on the basis of routine CM treatment could improve the somatic function, role function, emotional function, social function, cognitive function and general QOL of patients with advanced gastric cancer, and relieve the symptoms of fatigue, nausea and vomiting, pain, loss of appetite and constipation.

Sleep occupies one-third of a person's lifetime and is a necessary condition for maintaining physiological function and health. With the increase in social and economic pressures, the growing use of electronic devices and the accelerated aging process of the population, insufficient sleep and its hazards have drawn widespread attention from researchers in China and abroad. Sleep deprivation refers to a decrease in sleep or a severe lack of sleep due to various reasons. Previous studies have found that sleep deprivation can cause extensive damage to the body, including an increased incidence and mortality rate of neuropathic diseases in the brain, cardiovascular diseases, imbalances in the gut microbiota, and other multi-organ diseases. The mechanisms underlying the occurrence of multi-system and multi-organ diseases due to sleep deprivation mainly involve oxidative stress, inflammatory responses, and impaired immune function in the body. According to traditional Chinese medicine(TCM), sleep deprivation falls into the category of sleepiness, and long-term sleepiness leads to Yin-Yang imbalance, resulting in the consumption of Qi and damage to the five Zang-organs. The appropriate treatment should focus on tonifying deficiency, reinforcing healthy Qi, and harmonizing Yin and Yang. TCM is characterized by a wide variety and abundant resources, and it has minimal side effects and a broad range of applications. Numerous studies have shown that TCM drugs and prescriptions not only improve sleep but also have beneficial effects on liver nourishment, intelligence enhancement, and kidney tonification, effectively preventing and treating the body injury caused by sleep deprivation. Given the increasing prevalence of sleep deprivation and its significant impact on body health, this article reviewed sleep deprivation-mediated body injury and its mechanism, summarized and categorized TCM compound prescriptions and single drugs for preventing and treating body injury, with the aim of laying the foundation for researchers to develop effective drugs for preventing and treating body injury caused by sleep deprivation and providing references for further exploration of the molecular mechanisms underlying the body injury caused by sleep deprivation.
