Objective To assess the expression patterns of apoptosis-related genes in human pancreatic cancer cells (Patu-8988)induced by Kanglaite (KLT), a novel anti-cancer botanical product. Methods The apoptosis of Patu-8988 cells was determined by flow cytometry with Annexin V-FITC and propidium iodide staining. A human apoptosis microarray containing 96 cDNA fragments was used to detect gene expressions, and followed by Western blot analysis to confirm changes in expression of selected gene products. Results KLT induced apoptosis of Patu-8988 cells in a time-dependent manner. cDNA microarray analysis identified 5 down-regulated genes and 12 up-regulated genes (more than three fold) in the first 24 h as a consequence of treatment. Western blot performed for P53, Bcl-2, Bax and Caspase-3 were consistent with the microarray results. The enhanced activity of Caspases-3 was evidently verified by the cleavage of the 89?103 form of poly ADP-ribose polymerase. Conclusion KLT could alter the expression profile of apoptosis- related genes in human pancreatic Patu-8988 cancer cells, which provides valuable insight into the tentative signaling pathways mediating the outcome of KLT-induced apoptosis.

Objective To observe the expression of bag-1 and heat shock protein (HSP) 70 in clinical malignant tumors and the correlation between them. Methods RT-PCR and Immunohistochemistry were employed to examine the expression of bag-1 and HSP70 in 69 cases with gastroenteric cancer (54 cancer tissues and 15 non-cancer tissues). Results The expression of Bag-1 was detected in 96.3% of the cases, much higher than that in the control group (P0.05), and no correlation was observed between histological grade and HSP 70 expression. Conclusion There exists definite relationship between the gastroenteric cancer and the expression of bag-1 and HSP70, and there are close correlation between the tumor progress and the expression of bag-1.

AIM: To observe the effect of microRNA-16 (miR-16) on the megakaryocytic differentiation of K562 cells, and to explore the potential mechanism.METHODS:miR-16 was over-expressed or silenced by transfection with miR-16 mimics or inhibitor in K562 cells.The level of miR-16 was detected by real-time PCR.The expression of CD41, CD42b and CD61, as megakaryocytic differentiation markers, was detected by flow cytometry.The effect of miR-16 on the expression of myeloblastosis oncogene ( MYB) was measured by Western blotting, and flow cytometry was performed to confirm whether the effect of miR-16 on expression of CD41, CD42b and CD61 was mediated by MYB.RESULTS:Transfection with miR-16 mimics dramatically elevated the level of miR-16 and the expression of CD41, CD42b and CD61 in the K562 cells.Transfection with miR-16 inhibitor decreased the level of miR-16 and the expression of CD41, CD42b and CD61 in the K562 cells (P<0.05).The expression of MYB was regulated by miR-16, and MYB silencing reversed the regulation of CD41, CD42b and CD61 induced by miR-16.CONCLUSION:miR-16 regulates the megakaryocytic dif-ferentiation of K562 cells by targeting MYB.

Objective To explore the effects of transcranial magnetic stimulation (TMS) on motor function in patients with Parkinson's disease (PD) using meta-analysis. Methods Eight comparative studies of the effects of TMS were meta-analyzed. Results The combined studies confirmed a significant difference before and after TMS treatment. Between the experimental and control groups the effect was also highly significant. Conclusion TMS may play an active role in the rehabilitation of motor function for patients with Parkinson's disease.

Objective: To observe the effect of chronic psychological stress on change of function of learning and memory, and CD4, and CD8 in mice. Methods: 50 BALB/c mice were randomly divided into control group and immobilization stress group (n=25 in each group). The mice mode of stress was made by restraint for 6 hours per day. Suspend tail test was performed on change of behaviors in mice. RIA was employed to measure levels of neuropeptide Y in the brain. Results: Compared with the control group, the mean escape latency of the mice in the chronic restraint groups was longer than that of the control mice (P

This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR. Expressions of PAL1, C4H1, 4CL1, CHS1, CHI3 and HQT2 in buds were lower than that in leaves, and expressions of PAL3, 4CL2, CHI2 and FNS2 in buds were higher than that in leaves. The results indicated that that PAL3 and 4CL2 may be associated with accumulation of chlorogenic acid, and the expression patterns of PAL1, CHS1, CHI3 and HQT2 in buds and leaves of L. confusa were different with L. japonica. This study provided some theoretical basis for the further research on genetic mechanism of active components differences in L. confusa and L. japonica.

Objective To retrospectively analyze the lower extremity deep vein thrombosis prevention in patients with spinal cord injury (SCI). Methods A total of 115 SCI patients in our department from April to May, 2015 were included. The clinical symptoms, lower limb deep vein ultrasonic testing, laboratory examination were collected to analyze the occurrence, prevention measures, the thrombus location and management of deep venous thrombosis (DVT) in lower limbs. Results Forty-three patients had thromboprophylaxis in other hospitals before admission, and 105 patients in our department after admission, in which, nine cases were with clinical symptoms in other hospitals and three cases in our department. No pulmonary embolism occurred in them. There was no significant difference in most laboratory index-es between patients with DVT and without DVT in lower limbs (P>0.05). Five patients were with DVT in lower limbs in 43 patients who had thromboprophylaxis, and four cases in 72 patients who did not have thromboprophylaxis. No relationship was found between thrombo-prophylaxis and DVT in lower limbs (χ2=0.663, P=0.415). Five patients were with DVT in lower limbs in 53 patients with complete SCI, and four cases in 59 patients with incomplete SCI. No relationship was found between the severity of SCI and DVT in lower limbs in other hospitals (χ2=0.028, P=0.867). Conclusion DVT in lower limbs could be also occurred in patients who accepted thromboprophylaxis. Labo-ratory indexes are inadequate for the prediction and diagnosis specificity of DVT in lower limbs.

As the manual muscle testing is not sensitive enough to reflect the change of muscle strength, more and more people begin to use isokinetic dynamometry and handheld dynamometer for quantitative tests of muscle strength measurement. This paper briefly introduced the history of clinical approaches of muscle strength measurement, compared the advantages and disadvantages of various quantitative mus-cle strength testing, on which the specific techniques of clinical muscle strength measurement were discussed.

Study design Survey of expert opinion, feedback and final consensus. Objective To describe the development and the variables included in the International Spinal Cord Injury (SCI) Spinal Interventions and Surgical Procedures Basic Data set. Setting International working group. Methods A committee of experts was established to select and define data elements. The data set was then disseminated to the appropriate committees and organizations for comments. All suggested revisions were considered and both the International Spinal Cord Society and the American Spinal Injury Association endorsed the final version. Results The data set consists of nine variables: (1) Intervention/ Procedure Date and start time (2) Non-surgical bed rest and external immobilization, (3) Spinal intervention-closed manipulation and/or reduction of spinal elements, (4) Surgical procedure-approach, (5) Date and time of the completion of the intervention or surgical closure; (6) Surgical procedure-open reduction, (7) Surgical procedure-direct decompression of neural elements, and (8 and 9) Surgical procedure- stabilization and fusion (spinal segment number and level). All variables are coded using numbers or characters. Each spinal intervention and procedure is coded (variables 1 through 7) and the spinal segment level is described (variables 8 and 9). Sample clinical cases were developed to illustrate how to complete it. Conclusion The International SCI Spinal Interventions and Surgical Procedures Basic Data Set was developed to facilitate comparisons of spinal interventions and surgical procedures among studies, centers and countries.
