Objective To evaluate the combination of foot bath using tradirional Chinese medicine and foot massage on sleep quality of patients with insomnia. Methods 84 cases of insomnia patients were divided into the treatment group(44 cases) and the control group(40 cases)according to their willingness whether to accept foot bath and foot massage or not. The control group received routine care, the treatment group was given foot bath using traditional Chinese medicine and foot reflex zone massage at bedtime on the basis of the routine care. The treatment effect were evaluated after 10 days of continuous intervention. Pittsburgh Sleep Quality Index Scale (PSQI)was used to assess sleep quality of patients. Results The treatment efficacy and quality of sleep of the treatment group was significantly better than the control group. After treatment, sleep condition in the treatment group significantly improved than before. ConduMons The combination of foot bath using traditional Chinese medicine and foot massage can improve sleep quality in patients with insomnia.

Cancer stem cells (CSC) are related to the progression,recurrence and drug-resistance of tumor.MicroRNAs have been reported to correlate to the self-renewal of cancer cells.They can regulate cell cycle and thus interfere with the cell fate.Recent publications have clafified that microRNA can effect on cancer stem cells' self-renewal either by regulate targeted genes directly,or through wnt,notch and Hedgehog pathways.

Objective To investigate the retainage rate,distribution,and emigration of the bone marrow mesenchymal stem cell(BMMSC) after transcoronary infusion and to further evaluate the feasibility of injecting BMMSCs into coronary artery.Methods BMMSCs were isolated,purified,expanded,and labelled with CM-DiI.The infarcted SD rat hearts were removed and perfused with Langendorff apparatus.The cells were injected into the aortic root and the fluid returning from the coronary system was collected and the labelled cells in the coronary effluent were quantitated with flowcytometry.At the same time,left ventricle function was recorded to evaluate the safety of this approach.In vivo study,the cells were then injected into clamped ascending aorta through a catheter inserted through the left ventricle into the aortic root.The hearts were harvested at different time points after cell transplantation to obtain the direct evidence of distribution and emigration of the implanted cells.Results Only 3%～5% of transplanted cells returned into the right ventricle and more than 90% cells retained in the heart after beinginjected into aortic root of Langendorff model of infarcted hearts of SD rats.Left ventricle function did not deteriorate after cell transplantation.The labelled cells were entrapped within the coronary capillary immediately after cell infusion,mainly in the normal area.After 24 hours some cells migrated through the capillary wall into interstitium of the heart.One week later we found that most survival cells located at the infarcted area and the border zone.Conclusion The majority of BMMSCs delivered by transcoronary infusion retained in the heart.BMMSCs can penetrate the vessel wall and home back to the interstitial compartment and the injured area in a few hours.

Objective To observe the treatment effect of acupoint massage and auricular point sticking of cowherb seeds on blood pressure of hypertensive patients.Methods 100 cases of hypertensive patients were randomly divided into the observation group and the control group,50 cases in each.The observation group was given routine application of antihyportensive drags combined with acupoint massage and auricular point sticking of cowherb seeds.The control group received routine drug therapy.The blood pressure changes were compared between the two groups before and after treatment.Results The systolic blood pressure and diastolic blood pressure of both groups were lower after treatment compared with those before treatment.The total effective rate of blood pressure control was 98％ in the observation group,88％ in the control group,which showed no significant difference.Symptom control results showed that the total effective rate of the observation group was higher than that of the control group.Conclusions Acupoint massage and auricular point sticking of cowherb seeds in hypertensive patients can be an auxiliary pressure relief means,it can not only effectively lower blood pressure,but show good effect in alleviation of headache,vertigo,irritability.

BACKGROUND: Currently, most of the clinical trials of cell transplantation for ischemic heart disease is the transplantation of bone marrow mononuclear cells through the bypass graft artery in patients with acute myocardial infarction, but reports in combination with cell transplantation for old myocardial infarction are few. OBJECTIVE: To investigate the safety and feasibility of intracoronary artery injection of bone marrow mononuclear cells through the bypass graft artery during coronary artery bypass grafting (CABG). DESIGN: Self-control and case analysis. PARTICIPANTS: A total of 10 patients who had old myocardial infarction, left ventricular ejection fraction (LVEF)≤40%, were selected from Cardiovascular Institute and Fuwai Hospital from November 2004 to June 2005. METHODS: The bone marrow mononuclear cells were harvested from the bone marrow by Ficoll density gradient centrifugation method before the CABG was carried. And the patients received CABG and 10 mL mononuclear cell suspension through the grafts into anterior descending branch. In addition, 10 mL mononuclear cell suspension was injected into the circumflex branch and right coronary artery through the proximal heart. MAIN OUTCOME MEASURES: The heart function was evaluated with transthoracic echocardiography (TEE) and cardiac MRI after the operation. RESULTS: All patients recovered. A total of 45-60 mL bone marrow was harvested from iliac crest, and 4.1 ×10~7 mononuclear cells were isolated and identified by trypan blue test (cell activity >95%). TEE showed that the LVEF at 1 week and 1, 3 months postoperatively was significantly improved compared with before operation; creatase arid troponin T were not increased, and no myocardial infarction changes were found. MRI showed that the LVEF was significantly increased following operation (P < 0.01); left ventricular end-diastolic and systolic diameters were significantly decreased (P < 0.05). There was no complication associating with bone marrow harvest, or cell transplantation. CONCLUSION: Bone marrow mononuclear cells transplantation through bypass graft, as an adjunctive therapy, is safe and feasible.

Objective To investigate the effects of different DO2-directed hemodynamic man-agement on postoperative prognosis of orthotopic liver transplantation (OLT)patients with different degrees of liver function insufficiency.Methods Seventy patients (male 48 cases,female 22 cases, aged 37-66 years,ASA grade Ⅲ or Ⅳ)scheduled non veno-venous bypass OLT were divided into two groups (n = 35 each ).The oxygen delivery (DO2 )maintained respectively between 350 ml·min-1 ·m-2 and 500 ml·min-1 ·m-2 (group control)and more than 500 ml·min-1 ·m-2 (group study).After induction of anesthesia,the left radial artery was cannulated,allowing continu-ous blood pressure monitoring as well as serial blood sampling,then the Swan-Ganz catheter was in-serted via the right internal jugular vein to continuously monitor CI and S-vO2 .After anesthesia induc-tion and before operation (T1 ),10 min before anhepatic phase (T2 ),30 min after onset of anhepatic phase (T3 ),30 min after neohepatic phase (T4 )and the end of surgical procedure (T5 ),the SaO2 , PaO2 ,Hb,CI and S-vO2 were recorded to calculate the DO2 ,VO2 and ERO2 .Postoperatively,ICU and hospital length of stay,quality of life (QOL)and 1-5 year survival rate were recorded.Results In the two groups,CI,DO2 and VO2 declined at T3 to a statistically significant degree in comparison with T1 (P <0.05).CI,DO2 and VO2 in group study significantly higher than those of group control (P <0.05).ERO2 in group study was lower than that of group control significantly (P <0.05).ICU and hospital length of stay were significantly shorten in group study in comparison with group control (P <0.05).Survival rate and QOL in group study tended to be slightly higher than those of group control until the end of study period,but there was no significant difference.Conclusion The DO2-directed hemodynamic management can improve prognosis with enhanced DO2 in OLT patients with different degrees of hepatic insufficiency.It has a positive impact on their outcome of shortening ICU stay and the hospitalization days.

Objective:To evaluate high-risk human papillomavirus (hrHPV) genotyping and viral load in predicting CIN (cervical intraepi-thelial neoplasia (CIN) grade 2 or worse in a Chinese rural area population with limited health resources. Methods:We performed a population-based prospective study and enrolled 2,257 women aged 35 to 64 years from three rural screening sites of Jiangxi prov-ince. We conducted a hybrid capture (HC-2) assay to predict viral load. A HC-2 relative light unit (RLU) threshold of 10 was set to differ-entiate samples between low (<10) and high (≥10) viral loads. We also carried out a HybriMax test to detect different hrHPV geno-types in the samples. Women exhibiting positive HC-2 or HybriMax results underwent colposcopy and colposcopically directed biopsy. Women with negative or positive hrHPV test results but with normal biopsy or CIN1 were followed-up for 24 months without interven-tion (n=2,211). We used histopathological findings as outcome. Results:Of the 2,211 women, 1,636 provided complete follow-up data. Of the 132 women with a high viral load, 4 (3.03%) developed CIN2+in the same period. The relative risk (RR) of CIN2+for HC-2 posi-tivity at baseline was 42.24 (95%CI=4.76-375.2). Of the 159 women who were positive for HPV16 or HPV18 upon screening, 4 (2.52%) progressed to CIN2+(RR=33.06, 95%CI=3.72-293.9). The 2-year cumulative incidence rates of CIN2+did not significantly differ be-tween the high viral load group and the HPV16/18 group. Conclusion:The risks of CIN2+progression were higher among women with a high viral load or HPV16/18 positivity than among women with negative hrHPV. Increasing the HC-2 cut-off value to 10 RLU or using HPV16/18 positivity may be similarly used to triage hrHPV-positive women for immediate colposcopy and comprehensive follow-up.Both approaches were equally predictive of the CIN2+risk in rural area. Increasing the HC-2 cut-off value to 10 RLU may also help allo-cate health resources effectively.

Objectives:To analyze the clinical characteristics of patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) and identify the risk factors for death.Methods:The clinical data of 60 patients undergoing ECPR admitted to our hospital and Hangzhou First People's Hospital from September 2014 to September 2019 were retrospectively analyzed. The patients were divided into the survival group and the death group. The clinical data of the two groups were compared to explore the risk factors related to death. COX regression analysis was used to identify the risk factors for death.Results:Sixty patients undergoing ECPR were included in our study, of them, 16 (26.7%) cases were out-of-hospital cardiac arrest (OHCA) and 44 (73.3%) cases were in-hospital cardiac arrest (IHCA). The mortality of OHCA patients was higher than that of IHCA patients (87.5% vs. 56.89%, P < 0.05), and the duration from CPR to ECMO installation in the death group was longer than that in the survival group [(105.4±105.1) min vs. (53.0±28.5) min, P < 0.05]. Compared with the survival group, patients in the death group had higher troponin and glutamic oxalacetic transaminase and lower PH and lactate ( P < 0.05). The median survival time of the 60 patients was 42 days. Out-of-hospital cardiac arrest, high SOFA score before ECMO, high-dose norepinephrine, pulmonary infection during ECMO support and long ECMO support time were independent predictors of patients’ death. Conclusions:Risk factors associated with patients’ death undergoing ECPR are out-of-hospital cardiac arrest, high SOFA score before ECMO, high-dose norepinephrine, long duration from CPR to ECMO installation, pulmonary infection during ECMO support and long ECMO support time.

Microsatellite is a genetic marker, explored recently. In order to improve related studies on genetics of Anopheles gambiae, simple sequence repeats of the entire mosquito genome with 1～6 bp nucleotide motifs were analyzed.Abundance and distribution of microsatellites across the A.gambiae genome were analyzed and compared between various (exons, introns and intergenic) regions of all the chromosomes. About 2.14% of the mosquito genome was occupied by SSRs. Chromosome X had the maximum density of SSRs. Abundance orA repeats was similar to C repeats. AC was a little more than two times as abundant much as AG. However, AT and CG repeats were rare. For tri- and tetramer repeats, AGC,AAAC and AAAT predominated while ACG, ACT, AGG, CCG, ATGC, CCCG, ACTG, AACT, ACGT, AGAT, CCGG,ACCT and AGCT were rare. For some pentamer repeats, one was completely absent on a certain chromosome, even on several chromosomes. SSRs in exons of all chromosomes were less abundant than in introns and intergenic regions except for mono- and dimer repeats in exons of chromosome 2L. Abundance and distribution of SSRs on the two arms of each chromosome showed much in common.

Objective To explore the association between PI3K polymorphisms in insulin signal transduction pathway and Alzheimer's disease (AD)risk.Methods There were three groups,including 112 cases for AD +T2D group,231 cases for only AD group,and 231 cases for healthy controls group.The polymorphisms in PI3K gene was sequenced by PCR and the concentration of PI3K in serum was tested by enzyme -linked immunosorbent assay (ELISA).Results Overall,there was significantly statistical difference in PI3K rs3730087 polymorphism among three groups (χ2 =20.99,P =0.000 3).The CC frequency of PI3K rs3730087 polymorphism in AD with T2D group and AD control group was significantly higher than that in the healthy control group.The PI3K protein level of differ-ent genotype was statistically significant (F =27.450,P <0.000 1).As for CC genotypes of PI3K rs3730087 poly-morphism,the PI3K protein level was statistically different among these three groups (F =8.096,P =0.000 6).Moreover,the PI3K protein level of the three groups was different (F =9.034,P =0.000 1),which in both AD group was lower as compared with healthy control group.Conclusion The study suggested that CC genotype of PI3K rs3730087 polymorphism in insulin signaling transduction pathway might be a risk factor for AD with T2D and it also affects the expression level of PI3K protein.However,the polymorphism is not shown to be exclusive in AD patients with T2D.
