The recent literatures showed that the acupuncture therapy had played a special role in treating ischemic stroke, including the changes of fibrinolysis, amino acid neurotransmitters, active peptides, proteins in the blood, calmodulin, nitric oxide and the synthase, and so on. But the standard of judgments, the manipulations of acupuncture, the selection of acupoints, and the course of treatment remain uncertain.

The expression of matrix metalloproteinase-9 (MMP-9) after cerebral ischemia reperfusion injury can accelerate the damage of brain-blood barrier and plays an important role in brain edema after cerebral hemorrhage. The level of MMP-9 can reflex the severity of brain ischemia, indicate to the volume of infarct area and point out the prognosis of the disease. This article reviewed its source and expression,the gene regulation and polymorphism, hemorrhage transformation and nhibitors, and the mechanism was also analyzed.

Objective:To evaluate the association between weight gain in late gestation and glycated albumin (GA),visfatin level and neonatal body composition in gestational diabetes mellitus (GDM) patients who are non-obese.Methods:200 pregnant women were enrolled.The preconception body mass index(BMI) of all the research object was less than 25 kg/m2.According to the speed of body mass growth from 28th week of gestation to delivery,the subjects were divided into two groups:excessive weight gain group (n =77) and appropriate weight gain group(n=123).Variance of serum GA,visfatin levels and neonatal birth weight(BW),the percent of body fat in newborn(F％) between two groups were compared,and the relationship between weight gain in late pregnant GDM patients and above values was analyzed.Results:①Serum GA,HbA1 c,visfatin and total cholesterol,triglyceride,low density lipoprotein,very low density lipoprotein levels in excessive weight gain group were higher than those in appropriate weight gain group(P ＜ 0.05).②Mean gestational age,newborn Apgar score immediately,the ratio of baby boys and vaginal delivery rate in two group had no significant difference(P＞0.05).Compared with the appropriate weight gain group,the excessive weight gain group had higher average birth weight and lower blood glucose levels.The proportion of large for gestational ages(LGA) was increased in appropriate weight gain group,and the ratio of abdomen circumference (AC) and head circumference (HC) and the percent of body fat in newborn(F％) were significantly increased in this group(P ＜0.01).③The speed of body mass growth in late pregnancy in GDM patients was positively related with serum GA,visfatin,HbA1c levels and newborn birth weight and the percent of body fat in newborn(r=0.524,0.470,0.456,0.329,0.473,P＜0.001).Conclusions:The monitoring of the serum GA and visfatin levels may have certain clinical value to evaluate the weight gain in late pregnancy of GDM patients.The rapid body mass growth in those patients may accelerate the visceral fat accumulation and worsen existing glucolipid metabolic disorders,and is also closely related to the increase of neonatal BW and F％.

Positron emission tomography (PET) is one of the most advanced technology in the nuclear medicine currently. This paper reviewed the application of the PET in the acupuncture for clinical treatment in recent years.

The paper discussed inflammation related cells(including neutrophilic granulocyte, lymphocyte, monocytosis, macrophage, endothelial, vascular smooth muscle cells and glial cells), extracellular matrix even neurons and also their products(IL-1, IL-6, TNF-α, ICAM-1, ECM) interacted during ischemic stroke.

Objective To explore the changes in angiotensin Ⅱ(AngⅡ)produced by Langerhan islets of Syrian hamsters after blockage of renin-angiotensin system(RAS)by different inhibitors.Methods Islet cells from Syrian golden hamster were isolated and purified,and angiotensin Ⅰ was added.The experiment was then divided into six groups:control group(PBS was added),captopril group,chymostatin group,aprotinin group,?-antitrypsin group,and captopril+chymostatin group(according to inhibitors added).The content of AngⅡ in supernatant was detected by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,the AngⅡ content decreased by 42.50% and 50.94% in captopril group and chymostatin group,respectively(P

Objective Comparison of three different molecular assays for the detection and molecular characterization of circulating tumor cells in breast cancer .Methods The retrospective study compared three different molecular assays to detect CTC in the peripheral blood of 30 healthy individuals and 71 benign breast disease patients and 83 early and 84 metastatic breast cancer patients .All samples were collected at the outpatient , inpatient and physical examination department of Sichuan Provincial People ′s Hospital from January 2011 to June 2014.The same cDNAs were analyzed by:singleplex RT-qPCR assay for BCL-2, multiplex RT-qPCR for BCL-2, HER-2, HMAM, and a commercially available molecular assay (AdnaTest BreastCancer ) for GA733-2, MUC-1, HER-2.The positive of CTC were compared among healthy individuals and benign breast disease patients and breast cancer patients .Chi square test was used to compare the expression of gene markers among the three groups , and the agreement of Kappa test was used to evaluate the method.Results (1) Detection rates of early breast cancer by single RT-qPCR, Adna kits and multiple RT-qPCR were 13.3%, 16.9% and 18.1%, respectively , and the detection of metastatic breast cancer were 31.0%, 42.9%and 35.7%, respectively.There were significant differences in the positive of CTC by three molecular assays between healthy individuals and benign breast disease patients and early breast cancer patients ( The test values were 4.235 and 4.301, 5.367 and 5.474, 5.894 and 6.023 respectively, P<0.05).There were no differences between benign breast disease patients and early breast cancer patients (The test values were 0.891,0.748 and 0.701 respectively,P >0.05) .There were significant differences between metastasis breast cancer patients and healthy individuals and benign breast disease patients and early breast cancer patients ( The test values were 8.429,7.553 and 7.061;10.24, 9.025 and 8.745; 9.658, 8.417 and 8.201 respectively,P<0.05).(2) In early breast cancer: The concordance between AdnaTest and single RT-qPCR was 79.5%while between AdnaTest and multiplex RT-qPCR was 77.1%.No agreement was found among them ( The test values were 1.065 and 1.871, P were 0.371 and 0.258 ) .The concordance between single RT-qPCR and multiplex RT-qPCR was 80.7%.No agreement was found between them (The test values was 2.814, P was 0.156).(3) In patients with overt metastasis:The concordance between AdnaTest and single RT-qPCR was 78.6%( The test values was 10.986).While between AdnaTest and multiplex RT-qPCR was 80.9%( The test values was 9.251 ) . Agreements were found among them ( P was 0.002 and 0.005 respectively ) .The concordance between single and multiplex RT-qPCR was 88.1%( The test values was 12.364 ) .Agreement was found between them (P was 0.001).Conclusions No correlations were found among different molecular methods to detect CTC in the early primary breast cancer , but correlations were found in the metastatic breast cancer , suggesting that different rate of CTC caused by the number of CTC and its heterogeneity should be considered to the clinical diagnosis and treatment of breast cancer while molecular method is used .

Objective To investigate the enhanced osteogenesis during bone fracture healing after intracerebroven-tricular (ICV) leptin injection, using rabbit model with created segmental bone defect in right tibial. Method Segmental critical-sized defects were created at the right tibial bone of skeletally mature New Zealand white rabbits. In experiment group (leptin group), recombinant rabbit leptin was injected into cerebellomedullary cistern through foramen magnum. While in control group, normal saline was injected in the same way. Bone Mineral Density (BMD) was evaluated by qCT at 1st, 3rd, 7th, 14th and the 21st days. At the 21st days, all rabbits were euthanized to collect the right tibia for histomorphology, to ex-amine the BMP-2 expression in the bone callus by Fluorescence in situ hybridization (FISH). Result In the leptin group, body weight declined more obviously than control group then it start to arise at the 14th day;qCT showed significant higher BMD in leptin group than in control group at the 7th day;FISH showed a higher BMP-2 expression in leptin group than in control group. Conclusion Cerebellomedullary leptin injection through foramen magnum could accelerate limb fracture healing in rabbit model with right tibial bone defection.
