Objective:To evaluate the efficacy and safety of blood-letting therapy(BLT)in treatment of hypertension.Methods:A comprehensive electronic and manual bibliographic searches were performed in Cochrane Central Register of Controlled Trials,Excerpt Medica Database(EMBASE),PubMed,China National Knowledge Infrastructure,Chinese Scientific Journal Database,Chinese Biomedical Literature Database,and Wanfang Database to identify randomized controlled trials(RCTs)in which hypertensive patients were treated with BLT or BLT plus antihypertensive drugs(BPAD)against placebo,no treatment or antihypertensive drugs.The Cochrane Risk Assessment Tool was used to assess the methodological quality of trials.The Review Manager 5.3 software was used for meta-analysis.Results:A total of 7 RCTs with 637 hypertensive patients from 1989 to 2017 were identified.Compared with antihypertensive drugs,blood pressure was significantly reduced by BLT(RR=1.21,95%CI:1.01 to 1.44,P=0.03;heterogeneity:P=0.06,I^2=60%)and BPAD(RR=1.25,95%CI,1.02 to 1.53,P=0.03;heterogeneity:P=0.01,I^2=71%).Moreover,a significant improvement in Chinese medicine syndrome by BLT(RR=1.32;95%CI:1.14 to 1.53,P=0.0002;heterogeneity:P=0.53,I^2=0%)and BPAD(RR=1.47;95%CI:1.06 to 2.04,P=0.02;heterogeneity:P=0.13,I^2=56%)was identified.The reported adverse effects were well tolerated.Conclusions:Although some positive findings were identified,no definite conclusions regarding the efficacy and safety of BLT as complementary and alternative approach for treatment of hypertension could be drew due to the generally poor methodological design,significant heterogeneity,and insufficient clinical data.Further rigorously designed trials are warranted to confirm the results. 展开更多

Heating by electricity rather than coal is considered one effective way to reduce environmental problems. Thus, the electric heating load is growing rapidly, which may cause undesired problems in distribution grids because of the randomness and dispersed integration of the load. However, the electric heating load may also function as an energy storage system with optimal operational control. Therefore, the optimal modeling of electric heating load characteristics, considering its randomness, is important for grid planning and construction. In this study, the heating loads of distributed residential users in a certain area are modeled based on the Fanger thermal comfort equation and the predicted mean vote thermal comfort index calculation method. Different temperatures are considered while modeling the users’ heating loads. The heat load demand curve is estimated according to the time-varying equation of interior temperature. A multi-objective optimization model for the electric heating load with heat energy storage is then studied considering the demand response(DR), which optimizes economy and the comfort index. A fuzzy decision method is proposed, considering the factors influencing DR behavior. Finally, the validity of the proposed model is verified by simulations. The results show that the proposed model performs better than the traditional method. 展开更多

Objective: To assess the effect and safety of Huannao Yicong Formula (还脑益聪方, HYF) in the treatment of patients with mild-to-moderate Alzheimer's disease (AD). Methods: Sixty patients with mild-to moderate AD were evenly randomized into HYF group and donepezil group with the random number method. Patients in the HYF group took 5 g of HYF granules twice daily and 5 mg placebo of donepezil once daily. Patients in the donepezil group took 5 mg donepezil once daily and 5 g placebo of HYF granules twice daily. The intervention lasted for 6 months. Clinical researchers, participants and statisticians were blinded to the treatment assignment throughout the study. The primary outcomes were scores of Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Chinese Medicine Symptom Scale (CM-SS). The secondary outcomes were scores of Montreal Cognitive Assessment (MoCA) test and Mini-Mental State Exam (MMSE). The serum levels of acetylcholinesterase (AchE) and amyloid-β protein 42 (Aβ 42) were detected with enzyme linked immunosorbent assay kits. The scale assessments were conducted at baseline, the 3rd and 6th months of treatment, respectively. Biochemistry tests were conducted at baseline and the 6th month of treatment. Results: A total of 52 patients completed the trial, 28 in HYF group and 24 in donepezil group. Compared with the baseline, HYF and donepezil significantly decreased the total scores of ADAS-Cog and CM-SS, and significantly increased the scores of MoCA and MMSE after 6-month treatment (all P<0.01). Both treatments remarkably reduced the serum levels of AchE and Aβ 42 (both P<0.05). The CM-SS total effective rate of HYF was significantly higher than donepezil [75.00%(21/28) vs. 54.17%(13/24), P<0.05]. No severe adverse events were observed in both groups. Conclusion: HYF is effective and safe for improving the cognitive function in mild to-moderate AD patients.[Trial registration: Chinese Clinical Trial Registry (Reg No. ChiCTR-IOR-17011746)]. 展开更多

Objective: To evaluate the effect of tai chi exercise on cardiac and static lung function for older community-dwelling adults at risk of ischemic stroke. Methods: A total of 170 older community-dwelling adults (aged 55–75 years old) at risk of ischemic stroke were allocated to either tai chi training group (85 cases, five 60-min sessions of tai chi training per week for 12 weeks) or control group (85 cases, usual pbysical activity for 12 weeks) using a computer-generated randomization. The echocardiographic parameters of cardiac structure, cardiac function and static lung function were measured at baseline, after 12 weeks of intervention and additional 12-week follow-up period by a blinded professional staff member using a color Doppler ultrasound imaging device or a cardiopulmonary function instrument. The t test and linear mixed model based on the intention-to-treat analysis principle was used to calculate the effect. The adverse effect was observed. Results: Most of echocardiographic parameters on the cardiac structure, cardiac function and static lung function between the tai chi group and control group did not have a significant difference either post 12-week intervention or additional 12-week follow-up period. Only three parameters involving in right ventricular diameter (P=0.024), main pulmonary artery diameter (P=0.002) and vital capacity maximum (P=0.036) were beneficial to be improved in the tai chi group compared to the control group by the analysis of mixed linear model. No adverse effects were found during the intervention period. Conclusions: The 12-week tai chi exercise did not have an obvious beneficial effect on cardiac structure, cardiac function and static lung function in older community-dwelling adults at risk of ischemic stroke.(Trial registration No. ChiCTR-TRC-13003601) 展开更多

Objective: To evaluate the effect of Zhizhu Kuanzhong Capsules (枳术宽中胶囊, ZKC) for functional dyspepsia (FD) through meta-analysis. Methods: Online databases, including PubMed, EM base, China National Knowledge Infrastructure, Wanfang Data, VIP database and Cochrane Library, were searched for randomized controlled trials (RCTs) of ZKC for FD from the inception to April, 2016. Trials were selected according to inclusion criteria and were evaluated with quality assessment standards in the Cochrane Handbook for Systematic Reviews of Interventions and Jadad scale. RevMan 5.3 and GRADEprofiler 3.6 were used for statistical analysis and evidence quality assessment. Results: Twenty-three trials with 2,496 patients were included and most of them were of poor methodological quality. ZKC alone or ZKC combined with routine Western medicine (WM) showed a better clinical effect rate compared with the control group of WM [odds ratio (OR)=3.32, 95% confidence interval (2.66, 4.15), P<0.00001]. No serious adverse reactions were reported. Conclusions: ZKC alone or ZKC combined with routine WM could significantly improve the clinical effective rate in the treatment of FD. The quality of the evidence is low, so it is necessary to design multicenter, strictly randomized and double-blind controlled trials with large samples to validate the conclusions. 展开更多

Objective: This study aims to systematically evaluate the efficacy and safety of compound kushen injection (CKI) in combination with chemotherapy in patients with gastric cancer (GC). Methods: A comprehensive electronic search was conducted by searching PubMed, EMBASE, Cochrane Library, Chinese Biological Medical disc, China National Knowledge Infrastructure and Wanfang databases (the last update January 20, 2018). All randomized controlled trials (RCTs) of CKI plus chemotherapy versus chemotherapy alone in GC patients were identified. The quality of each study was evaluated using the Jadad’s scale, and the meta-analysis was performed using Review Manager 5.3 and STATA 14 software. Results: A total of nine studies on 688 cases were included in this study. The results showed that CKI combined with chemotherapy had a better effect on improving patients’ overall response rate (ORR) and life quality. The consequences of Egger’s and Begg’s tests showed there was no significant publication bias. Conclusion: The current evidence showed that CKI may enhance the clinical efficacy of chemotherapy, improve the quality of life and increase the safety in patients with gastric cancer. 展开更多

Malnutrition and mental health problems are both prevalent among rural students in China. To provide a better understanding of the functional linkage between these two problems, this study estimates the causal effect of improved nutrition on rural students’ mental health status, exploiting a randomized controlled trial involving 6 044 fourth and fifth graders in rural northwestern China. Estimation results show that a nutrition subsidy provided by the project significantly improved students’ mental health status(measured by their anxiety scale). However, an add-on incentive provided to school principals, which was tied to anemia reduction, almost entirely offset the beneficial impact of the nutrition subsidy. These findings suggest that to improve students’ mental health in rural China, not only direct subsidies, such as low-priced school meals, but also correct incentives, especially those tied closely to students’ mental health outcomes, should be provided. 展开更多

This paper proposes a day-ahead dispatch framework of thermostatically controlled loads(TCLs) for system peak load reduction. The proposed day-ahead scheduling framework estimates the user’s indoor thermal comfort degree through the building thermal inertia modelling. Based on the thermal comfort estimation, a dayahead TCL scheduling model is formulated, which consists of 3 stages: TCL aggregator estimates maximal controllable TCL capacities at each scheduling time interval by solving a optimization model;[ the system operator performs the day-ahead system dispatch to determine the load shedding instruction for each aggregator;and ′the TCL aggregator schedules the ON/OFFcontrol actions of the TCL groups based on the instruction from the system operator. A heuristic based optimization method, history driven differential evolution(HDDE)algorithm, is employed to solve the day-ahead dispatch model of the TCL aggregator side. Simulations are conducted to validate the proposed model. 展开更多

Due to their heat/cool storage characteristics, thermostatically controlled loads(TCLs) play an important role in demand response programmers. However, the modeling of the heat/cool storage characteristic of large numbers of TCLs is not simple. In this paper, the heat exchange power is adopted to calculate the power instead of the average power, and the relationship between the heat exchange power and energy storage is considered to develop an equivalent storage model, based on which the time-varying power constraints and the energy storage constraints are developed to establish the overall day-ahead schedulingmodel. Finally, the proposed scheduling method is verified using the simulation results of a six-bus system. 展开更多

A simple approach to synthesize ZnO microstructures was reported using dodecylamine,hexadecylamine and oleylamine as template agents.The synthesized ZnO was characterized by XRD,FESEM,TEM,EDS mapping,FTIR,UV-vis DRS,Raman spectroscopy and BET analysis.Hierarchical oriented ZnO microstructures were obtained.The photocatalytic performance of ZnO prepared with different types of alkylamines was evaluated by the degradation of methylene blue(MB)and methyl orange(MO).The results suggested that alkylamine control the nucleation,growth and morphology of ZnO.The photocatalytic properties of ZnO on the degradation of MB and MO decreased with increasing the alkyl chain length in alkylamine. 展开更多

Controlled islanding is considered to be the last countermeasure to prevent a system-wide blackout in case of cascading failures.It splits the system into self-sustained islands to maintain transient stability at the expense of possible loss of load.Generator coherence identification is critical to controlled islanding scheme as it helps identify the optimal cut-set to maintain the transient stability of the post-islanding systems.This paper presents a novel approach for online generator coherency identification using phasor measurement unit(PMU) data and dynamic time warping(DTW).Results from the coherence identification are used to further cluster non-generator buses using spectral clustering with the objective of minimizing power flow disruptions.The proposed approach is validated and compared to existing methods on the IEEE39-bus system and WECC 179-bus system, through which its advantages are demonstrated. 展开更多

This paper is based on the analysis and research on the silver-lead-zinc polymetallic ore in New Ballyhoo Banner in southern Manzhouli of Inner Mongolia.Because metal mineralization brings rock formations,the geophysical features such as low resistivity,high polarization rate and uneven distribution of magnetization,the comprehensive geophysical methods are adopted including high-precision magnetic measurement,high-power induced polarization,IP field middle gradient and controlled source audio-frequency magnetotellurics.In the survey work of multi-metal ore deposits,from surface sweeping to single point measurement,and from single point to section going deeper layer by layer,the resolution of measurement is continuously improved,and various geophysical methods support and complement each other,so explorers can successfully predict the direction,scale and volume of the metallogenic belts in conjunction with geochemical exploration,geological survey and drilling.It has provided a strong basis for completing the exploration task of predicting the reserve volume of ore bodies.The research conclusions of this exploration case have thus a high reference value in the same type of exploration work. 展开更多
