BACKGROUND:Bone marrow stromal stem cels transplanted into infracted cardiac tissue can inhibit and reduce myocardial apoptosis, but whether this effect is correlated with improvement in cardiac function is stil unclear. OBJECTIVE:To study the early effect of bone marrow stromal stem cels transplanted into the ischemic myocardium on the cardiac function. METHODS: Models of acute myocardial infarction were established by ligation of the left anterior descending branch, while no ligation was done in the sham group. In the transplantation group, rat bone marrow stromal stem cels (0.1 mL, 2×106 RESULTS AND CONCLUSION:At 3 days after cel transplantation, myocardial apoptosis was more evident in the infarct and ischemic zones of the model group than the sham group; the number of apoptotic myocardial cels was significantly lower in the infarct and ischemic zones of the transplantation group than the model group. Compared with the sham group, the mean arterial blood pressure and left ventricular systolic pressure were ) were injected into five sites on the edge of infarcted myocardial tissues at 30 minutes after myocardial infarction. In the sham group and model group, the same volume of normal saline was injected into the myocardial tissues. Three days after cel transplantation, hemodynamic monitoring, echocardiography, TUNEL assay were employed to detect myocardial apoptosis. significantly reduced, the left ventricular end diastolic pressure was increased, and the left ventricular ejection fraction and shortened fraction were significantly lowered in the model and transplantation groups (P < 0.05), but there was no difference between the model and transplantation groups (P > 0.05). These findings indicate that myocardial apoptosis can be reduced but the cardiac function cannot be improved in acute myocardial infarction rats at early stage after bone marrow stromal stem cels transplantation.

As a member of nuclear receptor superfamily, farnesoid X receptor (FXR) has been shown to regulate numerous metabolic pathways, which include playing an important role in bile acid metabolism, maintaining lipid and glucose homeostasis when FXR is activated. With the prevalence of the glucose and lipids disorder, FXR attracts increasing attention. It may be a potential target for the treatment of type 2 diabetes mellitus and lipid disorders.

BACKGROUND:The third molar extraction may lead to different degrees of soft tissue damage. Ultrasound and ultrashort waves belong to hyperthermia, which can increase tissue temperature and improve the therapeutic efficacy of soft tissue stretch. OBJECTIVE:To observe the effects of soft tissue stretch combined with ultrasound and ultrashort wave therapy for patients who were recently diagnosed with trismus and pain folowing third molar removal. METHODS:Sixteen patients with trismus and pain after third molar removal were randomly divided into two groups: patients in stretch group received soft tissue stretch with ultrasound and ultrashort wave therapy, while those in control group received only ultrasound and ultrashort wave therapy. Patients received the treatment five times per week, totaly for 2 weeks. RESULTS AND CONCLUSION:It was found that after treatment pain was significantly reduced at the temporomandibular joint, and the range of maximum active mouth opening increased significantly. The improvement in mouth opening and temporomandibular joint function was better in the stretch group than the control group. These findings indicate that ultrasound and ultrashort wave therapy can improve symptoms of trismus and pain folowing third molar removal, and the combination of ultrasound and ultrashort wave therapy and soft tissue stretch therapy can achieve more effective results.

Objective To establish an accurate sorting method with less interference to the cell activity for isolating CD 3+CD4+T lymphocytes in human intestinal tissue .Methods Firstly the digestive enzymes were adopted to decompose the human intestinal tissue ,and then the cell suspension was obtained by the filtration of 40 μm cell strainer .Mononuclear cells were collected by using continuous density Percoll gradient centrifugation technique ,then the flow cytometry was adopted to sort CD3+ CD4+ T lympho-cytes in mononuclear cells .The survival rate ,cell purity and morphological observation of the sorted cells were adopted to conduct the evaluation on the sorting method .Results The digestive enzymes well decomposed human intestinal tissue into cell suspension , the purity of CD3+CD4+ T lymphocytes by using continuous density Percoll gradient centrifugation was (43 .9 ± 7 .3)% ,while the purity of CD3+CD4+ T lymphocytes was(96 .9 ± 1 .2)% after fluorescence-activated cell sorting ,the difference between them was statistically significant(P<0 .01) .The survival rate of sorted CD3+CD4+ T lymphocytes was(97 .8 ± 1 .6)% with intact cell shape . Conclusion The Percoll gradient centrifugation technique combined with the fluorescence-activated cell sorting not only collects highly pure human intestinal CD3+CD4+ T lymphocytes with little influence on the cell activity and shape ,but aslo may be carried out under sterile conditions ,the sorted cells can continue to be used in the other functional researches .

Objective:To establish an HPLC method for the determination of related substances in piperazine ferulate. Methods:An HPLC method was used to determine the related substances in piperazine ferulate. The separation was performed on an Xtimate C18 column (250 mm × 4. 6 mm, 5 μm). The mobile phase was 0. 5% acetic acid-methanol-acetonitrile with gradient elution. The flow rate was 1. 0 ml·min-1 and the column temperature was 30℃. The detection wavelength was 286 nm and the injection volume was 20μl. Results:Ferulic acid had a good linear relationship within the range of 5-30 μg·ml-1(r=1.0000). The detection limit was 0. 02 ng. Conclusion:The method is reliable, simple, accurate, stable and durable, and suitable for the determination of related sub-stances in piperazine ferulate.

BACKGROUND:A number of studies have shown that there are many inducible methods by which bone marrow mesenchymal stem cel s can differentiate into hepatocytes, but the specific molecular mechanism is unclear yet. OBJECTIVE:To review the programs and underlying mechanisms by which bone marrow mesenchymal stem cel s differentiate into hepatocytes. METHODS:A computer-based online search of CNKI, VIP, WanFang and PubMed databases was performed to retrieve articles about directional differentiation of bone marrow mesenchymal stem cel s into hepatocytes published between 2004 and 2015. The key words were“hepatocyte (-like) cel s, bone marrow mesenchymal stem cel s, differentiation”in Chinese and English, respectively. Final y, 62 articles were included in result analysis. RESULTS AND CONCLUSION:There are many programs for hepatic differentiation of bone marrow mesenchymal stem cel s, but the specific molecular mechanism is stil unclear. Many studies mainly focus on Notch signaling pathway, Wnt/β-catenin signaling pathway, P38 signal pathway, miR-122 and effect of calcium ions. Bone marrow mesenchymal stem cel s that can be induced to differentiate into mature hepatocytes provide an ideal cel ular source for hepatocyte transplantation and artificial liver, which is proposed to be a new strategy for clinical treatment of end-stage liver disease.
