Objective To observe the effect of auricular point sticking plus breast massage with rehabilitation apparatus on lactation in the puerperant. Methods Totally 127 in-hospital primiparae were randomized into a treatment group of 62 cases and a control group of 65 cases. The control group was intervened by conventional nursing care, while the treatment group was by auricular point sticking plus breast massage with rehabilitation apparatus in addition to the conventional nursing care. The lactation yield, initial lactation time, and the change of prolactin (PRL) were observed. Results There were significant differences in comparing the lactation yield grading and initial lactation time between the two groups (P＜0.05). There were significant differences in comparing the serum PRL level on the postpartum day 1, 2, and 5 between the two groups (P＜0.01, P＜0.05). Conclusion Auricular point sticking plus breast massage with rehabilitation apparatus can promote milk secretion, the initial lactation time, PRL production, and the breast feeding rate.

The proliferation of vascular smooth muscle cells is closely related to the pathogenesis of a variety of diseases, such as atherosclerosis, hypertension, diabetes, vascular restenosis, and etc. A proper model for smooth muscle cell proliferation can be served as an important tool for exploring the molecular mechanisms of smooth muscle cell proliferation and the screening of potential inhibitory agents. Various factors can induce the proliferation of smooth muscle cells with different mechanisms and pathological significance. The ox-LDL, AGEs, angiotensin II (AngⅡ), high glucose, tumor necrosis factor (TNF) and etc. have been successfully applied in the establishment of smooth muscle cell proliferation model. This article summarized the most commonly used models for smooth muscle cell proliferation. The inhibitory effects of Chinese herbal medicine, especially the isolated pure compounds were discussed. It was aimed to provide references for the screening of smooth muscle cells based medications as well as studies on related research and development of Chinese herbal medicine.

Objective To learn the present pre-hospital emergency resources allocation in Liaoning province.Methods Site survey and questionnaire survey were used to survey the basic information,number of pre-hospital emergency ambulances,human resources,and communication/control systems of 19 pre-hospital emergency centers in Liaoning province in 2014.Results The number of pre-hospital emergency sub-stations,ambulances and human resource fall short of demand.Furthermore,these resources are found with such problems as greater service radius of average pre-hospital emergency service and longer average pre-hospital response time in countryside than cities,insufficient and obsolete ambulances short of onboard equipment and communication systems,not to mention shortage of medical workers of higher degrees and academic titles.Conclusions A great gap is found between urban and rural pre-hospital emergency resource allocation in Liaoning province,with poor resources in the countryside.The government is recommended to step up financial support in increasing pre-hospital emergency substations and resources allocation,regularly update pre-hospital emergency vehicles,set up independent title promotion mechanism,perfect communication scheduling system,in order to satisfy the demands of pre-hospital first aid.

Objective To investigate the effect of exogenous apelin-13 on oxidative stress, myocardial inflammatory cytokines and apoptosis in diabetic model rats.Methods A total of 40 male Wistar rats were randomly divided into 2 groups: normal control group (NC, n=8) and experimental group (EX, n=32).Diabetes was induced by feeding with high-sugary and high-fat diet for 8 weeks and a single intraperitoneal injection of streptozotocin (STZ) (30 mg/kg).The wellestablished 28 diabetic model rats were then randomly divided into 2 subgroups: model group (DM, n =14) and apelin-13 administration group (AP, n =14).The rats in AP group were given intraperitoneal administration of apelin-13 at a single dose of 0.1 μtmol · kg-1 · d-1 for 10 weeks, while NC group and DM group were given 0.9％ NaCl in the same way.All rats were sacrificed at the end of the week 10.Blood hydrogen peroxide (H2O2), nitric oxide (NO) and malonaldehyde (MDA) were measured by colorimetry, and superoxide dismutase (SOD) was measured by enzyme-linked immunosorbent assay (ELISA).The expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in rat myocardium were detected by immunohistochemistry.Masson staining was used to observe the myocardial fibrosis in rats of different groups.Cardiomyocyte apoptosis was determined by TUNEL.Results (1) Compared with NC groups, DM group showed that MDA, H2O2 and NO were significantly increased, while SOD was significantly decreased (F=22.400, 6.230, 4.267 and 8.901, all P＜0.0167).There was a statistically significant difference in the levels of MDA, H2O2,SOD between DM group and AP group.(2) The expression of TNF-α and IL-6 was significantly higher inDMgroup than inNCgroup (0.0599±0.0208 vs.0.0076±0.0031, F=35.139;0.0503±0.0243 vs.0.0071± 0.0024, F=15.946, both P＜0.0167).After 10 weeks of apelin-13 administration, the levels of inflammatory cytokines were significantly decreased in AP group than in DM group.(3) The myocardial apoptosis and fibrosis were significantly increased in DM group than in NCgroup [0.0293±0.0061 vs.0.0030-t-0.0013 and 0.0708±0.0420 vs.0.0013±0.0003, F=84.930 and 19.420, both P＜0.0167].The myocardial apoptosis and fibrosis were significantly decreased in AP group than in DM group (both P＜0.0167).Conclusions To some extent, apelin13 reduces the levels of oxidative stress and myocardial inflammation reaction in type 2 diabetes.Moreover, it may play a vital role in the improvement of myocardial apoptosis and fibrosis.

Objectives To investigate the effects of Apelin 13 on myocardial metabolism in diabetic rats.Methods A total of 40 male Wister rats were randomly divided into normal control group (NC,n=8) and experimental group (n =32).Diabetic rats model were induced by high-sugar and high-fat diet combined with low-dose intraperitoneal injection of streptozotocin (STZ).The wellestablished 28 diabetic model rats were randomly divided into diabetic model group (DM,n=14) and apelin-13 treated group (n=14).In the Apelin-13 group,diabetic rats were administered Apelin-13 [0.1 μmol/(kg · d)]by intraperitoneal injection for 10 weeks,while the control group and diabetic model group were given an equal volume of 0.9％ NaCl.At the end of the 10th week,all rats were sacrificed after fasting glucose measurement.Levels of serum free fatty acids (FFA) and myocardial FFA were measured by ELISA.Expression of myocardial glucose transporter member 4 (GLUT4) were detected by immunohistochemistry.The mRNA expressions of myocardial PPARα,CD36 and CPT-1 were detected by real-time fluorescence quantitative PCR.Results Fasting blood glucose,serum FFA and myocardial FFA were significantly higher in DM group than in NC group (all P＜ 0.05).The level of plasma glucose and myocardial FFA were significant lower(P＞0.05) in Apelin-13 treated group than in DM group;but serum FFA was not significantly lower(P＜0.05).The mRNA expressions of PPARα,CD36,CPT-1 in cardiac myocyte were higher in DM group and Apelin-13 treated group than in control(P＜0.05),and lower in Apelin-13 treated group than in DM group(P＜ 0.05).The expression of myocardial GLUT4 was significantly lower in DM group(1.138±0.316)and in Apelin-13-treated group (4.631 ± 1.832) than in NC group(9.132 ± 2.156),(F=65.507,P＜ 0.05),and higher in Apelin-13-treated group than in DM group(P＜0.05).Conclusions Apelin-13 increases myocardial expression of GLUT4,improves utilization of FFA,and it can effectively reduce the expression of PPARα,CD36 and CPT-1.Therefore,it may play a vital role in the improvement of myocardial metabolism in diabetic rats.
