Objective To observe the effects of oldhamianoside Ⅱ on the invasive 'ability of prostatic carcinoma DU-145 cells,and to investigate the potential mechanism.Methods After treatment of DU-145 cells with oldhamianoside Ⅱ,MTT assay was used to test the effect of oldhamianoside Ⅱ on the cell proliferation.The invasive ability was assessed with a transwell cell culture chamber.Immunocytochemistry stain was used to investigate the expression of matrix metalloproteinase(MMP-2)and CXC-chemokine receptor 4 (CXCR4).Results The proliferation of DU-145 cells was inhibited after treatment with oldhamianoside Ⅱ.In vitro invasion assay indicated that the cells moved through the membrane were(180.3 ± 14.6)/field in the control group,while decreased to(100.4 ±1.5),(80.2±2.7)and(60.1 ±5.3)/field in 0.25,0.5 and 1μg/mL oldhamianoside Ⅱ treated DU-145 cells respectively.Comparing to control group,the cells of oldhamianoside Ⅱ groups moved through the membrane were decreased remarkably(P ＜0.05).Immunocytochemistry showed that the expression of MMP-2 and CXCR4 were decreased of oldhamianoside Ⅱ groups.Conclusions Oldhamianoside Ⅱ can inhibit the invasiveness of DU-145 cells,which is related to the down regulation the expression of MMP-2 in DU-t45 cells.Oldhamianoside Ⅱ can inhibit the prostate cancer cells metastasis to the bone,which is related to the down regulation the expression of CXCR4 in DU-145 cells.

BACKGROUND:Adipose-derived mesenchymal stem cels have rich sources that are easily obtained, which can be used to treat acute myocardial infarction. OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cel transplantation on acute myocardial infarction in rats. METHODS:Rat models of acute myocardial infarction were made and subjected to adipose-derived mesenchymal stem cel transplantation in comparison with model and control (sham operation) groups. RESULTS AND CONCLUSION:Echocardiography findings showed significant improvement in the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ejection fraction in the cel transplantation group compared with the model group (P < 0.05). Hematoxylin-eosin staining showed that myocardial infarction was evident in the model group, in which, there were rarely viable myocardial tissues and few vessels in the infarcted region, but in the cel transplantation group, there were evident survived myocardial tissues and transplanted cels. The percentage of infarct size was significantly lower in the cel transplantation group than the model group (P < 0.05). Immunohistochemical staining showed that adipose-derived mesenchymal stem cels were able to survive in the infarcted myocardial tissues, and the expression of cardiac troponin T in the cel transplantation group was significantly higher than that in the model group (P < 0.05). Experimental data show that adipose-derived mesenchymal stem cel transplantation can protect the myocardial tissues after myocardial infarction, and effectively improve the myocardial function.

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

Background Evidences, from recent studies, suggested that Borna disease virus (BDV) infection might be associated with human neuropsychosis, especially psychiatric disorders including depressive disorder(DD). However, controversy existed about the association between BDV infection and pathogenesis of DD. This study was to explore further whether the infection of Borna disease virus (BDV) is associated with the pathogenesis of depressive disorder (DD).Methods The p 24 fragment of BDV RNA in peripheral blood mononuclear cells (PBMCs) from 60DD patients and 120 healthy volunteers was detected by nested reverse transcriptase polymerase chain reaction (nRT-PCR) combined with fluorescence quantitative polymerase chain reaction (FQPCR). Positive products were cloned and sequenced before being compared with Strain V and strain He/80, from humans and animals.Results The positive rate (5%, 3/60) of BDV p 24 in PBMCs from the DD patients was significantly higher than that (0%, 0/120) from healthy volunteers ( P＜0. 05). The gene sequence for the positive products showed BDV p 24 in PBMCs from DD patients in Chongqing was most homophylic with H1766 strain detected from iii horses (97.68%), with 2 situs mutations (nt 1675 T→C, nt 1678 C→T), and also similar to the standard strain V(96. 51%)and He/80(95.35 %), with basic exchanges limited to T- C and A→G.Conclusions There was BDV infection in the DD patients in China, which indicated that the pathogenesis of DD in human beings in Chongqing might be associated with the infection of BDV.

Objective:To identify the cerebral activation patterns associated with the processes that occur during viewing Chinese and English words in native Chinese English learners.Methods:12 right-handed Chinese English hamers were divided into two groups equally,namely English majors and non-English majors,and took semantic judgement tasks of both English and Chinese words,for whom the fMRI images were coUected.Results:To various degrees,all subjects demonstrated activation of associated cerebral regions in both hemispheres and the left hemisphere activation was more significant for most subjects.Except for elassieal regions involved in language processing,such as Wemicke areas and Broca areas,there were other activated cerebral regions,including cerebellum,limbic system and basal ganglia nucleus,etc.To sum up,there were apparent overlap for cerebral activation distribution and no specific processing areas for both tasks.The analysis of ROI(region of interest)suggested that subjects in specialized group were more dependent on right hemisphere to perform English words task.Conclus/on:Language cognition is dominated by left hemisphere,which is also shared by the right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere in English task is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.

BACKGROUND: This study aimed to observe the effect of hemoperfusion (HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning. METHODS: The levels of internal environment indicators (blood pH, PvCO2, PvO2, blood lactate, potassium, free calcium, bicarbonate, and blood glucose) before and after HP treatment were recorded for patients with acute poisoning at time points of 30 minutes and 120 minutes. After calculating the difference value δ, the statistical software was used to analyze the statistical difference of the influencea-v caused by HP cartridge at two time points. According to the formula, adsorption rate %= —— ×100, thea adsorption rate of each indicator was calculated respectively. RESULTS: The difference of indicators at different time points in inlet and outlet such as blood glucose, free-calcium, and lactate was statistically significant (P<0.05), but the difference in indicators such as pH, PvCO2, PvO2, potassium, sodium, and bicarbonate was not statistical y significant (P>0.05). CONCLUSION: During HP treatment, the indicators of blood glucose, free-calcium and lactate were significantly affected by HP cartridge, and the effect varies with time.
