Objective:To study the effect of electroacupuncture (EA) at the Pericardium Meridian on the heart function of volunteers with acute hypoxia, and to provide scientific evidence for the acupoints selection along the affected meridian in acupuncture-moxibustion therapy. Methods:Based on a self-control design, eighteen healthy volunteers were recruited in the study. Points from the Pericardium Meridian [Neiguan (PC 6), Ximen (PC 4), Quze (PC 3) and Tianquan (PC 2)], non-Pericardium Meridian point [Shousanli (LI 10)], non-meridian and non-acupoint points [1.0-1.5 cm lateral to Neiguan (PC 6) and Ximen (PC 4), respectively on both sides], and a blank control (only inhaling low-oxygen gas without EA stimulation) were selected to observe, once every week, 10 sessions in total, and only 1 acupoint was observed once. The volunteers inhaled low-oxygen gas mixture (10.8% O2 and 89.2% N2) for 30 min to imitate acute hypoxia. EA was conducted when the gas mixture was inhaled for 10 min and then lasted for 20 min; meanwhile, hemodynamic indexes such as cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI), left cardiac work (LCW), left cardiac work index (LCWI) and heart rate (HR) were recorded on a hemodynamic monitor. Results:EA at the acupoints of Pericardium Meridian significantly down-regulated the increased CO/CI, LCW/LCWI, and HR (P<0.05), and significantly up-regulated the decreased SVR/SVRI in hypoxia (P<0.05); EA at other meridian acupoints or at non-meridian and non-acupoint points didn't produce such effects. Conclusion: EA at the Pericardium Meridian can obviously improve the cardiac hyper-activation caused by acute hypoxia in healthy volunteers.

Objective Blood pressure variability (BPV) is an independent risk factor for the death of patients with maintenance hemodialysis (MHD).There is no study on the influencing factors of BPV at home in HD patients in China.The article aimed to investigate MHD patients'BPV at home and related influencing factors in order to provide theoretical basis for reducing home BPV (HBPV) clinically. Methods We chose 103 patients who were treated with MHD in the Renal Medicine Room of Nephrology Department in three upper first -class hospitals including Jiangsu Provincial People 's Hospital, the First Affiliated Hospital of Suzhou University and the Affiliated Hospi -tal of Jiangsu University from March 2017 to October 2017.We col-lected their 7 days'blood pressure monitoring at home and blood pressure before dialysis, average value and standard deviation in sys -tolic blood pressure monitoring at home, and took the coefficient of variation of systolic blood pressure as the expression of HBPV .The patients were divided into high BPV group (BPV≥5.8%) and low BPV group (BPV<5.8%) according to the average BPV.At the same time, we recorded indexes such as sex , age, dialysis age, primary disease, BMI, inter-dialytic weight gain (IDWG), left ven-tricular mass index(LVMI) and analyzed relative influencing factors by multiple linear regression . Results The age, IDWG and LV-MI were positive independent influencing factors of HBPV (R 2 =0.467,F=10.945,P<0.001).According to standardized regression co-efficient, the contribution of each variable to HBPV was as follows : PIBWG >Age>LVMI. Conclusion In clinical nursing, we should actively control the IDWG of patients , encourage patients to monitor their blood pressure at home , and increase their awareness of the importance of home BPV.Meanwhile, HBPV is an important index for predicting left ventricular hypertrophy and can be used as an objective tool to improve patients 'self-management ability.

It is unanimously accepted that stroke is a highly heterogeneous disorder.Different subtypes of ischemic stroke may have different risk factors,clinical features,and prognoses.The aim of this study was to evaluate the risk factors,clinical characteristics,and prognoses of different subtypes of ischemic stroke defined by the Trial of ORG10172 in Acute Stroke Treatment (TOAST) criteria.We prospectively analyzed the data from 530 consecutive patients who were admitted to our hospital with acute ischemic stroke within 7 days of stroke onset during the study period.Standardized data assessment was used and the cause of ischemic stroke was classified according to the TOAST criteria.Patients were followed up till 30 and 90 days after stroke onset.It was found that large-artery atherosclerosis was the most frequent etiology of stroke (37.4%),and showed the highest male preponderance,the highest prevalence of previous transient ischemic attack,and the longest hospital stay among all subtypes.Small artery disease (36.4%) was associated with higher body mass index,higher plasma triglycerides,and lower plasma high-density lipoprotein cholesterol than cardioembolism.Cardioembolism (7.7%),which was particularly common in the elderly (i.e.,individuals aged 65 years and older),showed the highest female preponderance,the highest prevalence of atrial fibrillation,the earliest presentation to hospital after stroke onset,the most severe symptoms on admission,the maximum complications associated with an adverse outcome,and the highest rate of stroke recurrence and mortality.Our results suggest that ischemic stroke should be regarded as a highly heterogeneous disorder.Studies involving risk factors,clinical features,and prognoses of ischemic stroke should differentiate between etiologic stroke subtypes.

The impact of prior cesarean section (CS) on the pregnancy and neonatal outcomes of in vitro fertilization and embryo transfer (IVF-ET) was investigated.A retrospective analysis was performed on 144 patients with prior CS between January 2013 and December 2015.The pregnancy,delivery,and neonatal outcomes of patients who had previous CS delivery and received IVF-ET were analyzed.The control group comprised 166 patients who had only previous vaginal delivery (VD) and received IVF-ET during the same period.The results showed that the basal follicle stimulating hormone level,estradiol level on human chorionic gonadotropin (hCG) day,gonadotrophin dosage,duration of stimulation,retrieved oocytes,fertilization rate,high-quality embryo rate,multiple birth rate,abortion rate and ectopic pregnancy rate had no significant difference between the two groups (P>0.05).The pregnancy rate (40.28% vs.54.22%) and implantation rate (24.01% vs.34.67%) were significantly lower (P<0.05),and the ratio of embryo difficulty transfer (9/144 vs.0/166) was significantly higher in CS group than in VD group.The risk of pernicious placenta previa and postpartum hemorrhage in twin deliveries was significantly increased in CS group as compared with that in VD group (P<0.05),and gestational age and neonatal birth weight were significantly reduced in twin deliveries as compared with singleton deliveries in both groups (P<0.05).It was suggested that the existence of CS scar may impact embryo implantation and clinical pregnancy outcome,and increase the difficulty of ET.We should limit the number of transfer embryos to avoid multiple pregnancies and strengthen gestational supervision in patients with cesarean scar.
