Objective: To evaluate the clinical effects of combined acupuncture and ear-puncture in treating renal colic. Methods: Sixty subjects were randomized into an acupuncture group and a medication group, 30 in each, to receive acupuncture and Western medicine respectively. The analgesic effects and pain relief time were measured in both groups. Results: Both of the two groups got pain relieved or reduced. The total effective rate was 89.7% in the acupuncture group, significantly superior to 77.4% in the medication group (P<0.05). Conclusion: Combined body and auricular acupuncture is efficient in relieving pain in treating renal colic, and its effective rate was higher compared with medication treatment.

BACKGROUND:Cytochrome P450 ( CYP) epoxygenases metabolize arachidonic acids ( AA) to form epoxyeicosatrienoic acids
(EETs), which exert beneficial roles in the treatment of cardiovascular diseases , but little is known about its role on adventitial remo-deling.METHODS:We used C57BL/6J mice in vivo and primary rat adventitial fibroblasts ( AFs) in vitro treated with angiotensin II (Ang II) to investigate the effects of CYP2J2 gene delivery and exogenous EETs administration on adventitial remodeling .RESULTS:CYP/sEH system was found to exist in human adventitia , and involved in adventitial remodeling process .Exogenous EETs administra-tion significantly inhibited Ang II-induced AFs activation , characterized by differentiation , proliferation, migration, and collagen syn-thesis.These protective effects were partially reversed by PPARγantagonist GW9662 pretreatment or SOCS3 siRNA transfection.EETs suppressed Ang II-induced IκBαphosphorylation , subsequent NF-κB nuclear translocation via PPARγdependent signaling pathway in AFs.Additionally, EETs reduced Ang II-induced JAK2, STAT3 phosphorylation and subsequent phosphor-STAT3 nuclear transloca-tion, which were mediated by SOCS3 induction but independent of PPARγactivation.Furthermore, rAAV-CYP2J2 gene delivery re-duced vessel wall thickening , AFs differentiation , proliferation and collagen deposition in aortic adventitia induced by Ang II infusion , which were mediated by NF-κB and SOCS3/JAK/STAT signaling pathways in blood pressure-dependent and -independent manners , re-spectively.CONCLUSION:We concluded that CYP2J2 overexpression attenuated Ang II-induced adventitial remodeling via PPARγ-dependent NF-κB and PPARγ-independent SOCS 3/JAK/STAT inflammatory signaling pathways .

Background: Global spread and impact of the coronavirus disease 2019 (COVID-19) pandemic are determined to a large extent,by resistance to the pandemic and public response of all countries in the world;while a country's resistance and response are in turn determined by its political and socio economic conditions.To inform future disease prevention and control,we analyzed global data to exam the relationship between state vulnerabilities and COVID-19 incidences and deaths.Methods: Vulnerability was measured using the Fragile States Index (FSI).FSI is created by the Fund for Peace to assess levels of fragility for individual countries.Total FSI score and scores for 12 specific indicators were used as the predictor variables.Outcome variables were national cumulative COVID-19 cases and deaths up to September 16,2020,derived from the World Health Organization.Cumulative incidence rates were computed using 2019 National population derived from the World Bank,and case fatality rates were computed as the ratio of deaths/COVID-19 cases.Countries with incomplete data were excluded,yielding a final sample of 146 countries.Multivariate regression was used to examine the association between the predictor and the outcome measures.Results: There were dramatic cross-country variations in both FSI and COVID-19 epidemiological measurements.FSI total scores were negatively associated with both COVID-19 cumulative incidence rates (β =-0.0135,P ＜ 0.001) and case fatality rates (β =-0.0147,P ＜ 0.05).Of the 12 FSI indicators,three negatively associated with COVID-19 incidences were E1(Economic Decline and Poverty),E3 (Human Flight and Brain Drain),and S2 (Refugees and Internally Displaced Persons);two positively associated were P1 (State Legitimacy) and X1 (External Intervention).With regard to association with case fatality rates,C1 (Security Apparatus) was positive,and P3 (Human Rights and Rule of Law) and X1 was negative.Conclusion: With FSI measures by the Fund of Peace,overall,more fragile countries are less likely to be affected by the COVID-19 pandemic,and even if affected,death rates were lower.However,poor in state legitimacy and lack of external intervention are risk for COVID-19 infection and lack of security apparatus is risky for COVID-19 death.Implications of the study findings are discussed and additional studies are needed to examine the mechanisms underpinning these relationships.

This article introduces a high-throughput molecular screening chip： peptide arrays. As a kind of biochip， the peptide arrays are easy to synthesis， stable in probe chemistry， high-throughput in screening and highly specific compared with other biochips. To analyze the new high-throughput data， researchers have recently proposed a series of deep learning and bioinformatics methods to study the binding characteristics of peptide probes and target molecules. Those algorithms could be used to predict the binding affinity of protein targets against peptides. Moreover， peptide arrays could also play important roles in analyzing protein-protein interactions，screening novel drug peptides， disease diagnosis and general health assessment based on recent reports. The application of this new technology could provide novel insights into public health research.

The outbreak of COVID-19 has spread quickly across 114 countries/territories/areas in six continents worldwide and has been announced as a pandemic by WHO. This study analyzed global COVID-19 epidemiological trends, examined impact of the pandemic on global health security, diplomacy, and social environment in China, and provided short- and long-term strategic policy recommendations for China’s subsequent preparedness and responses.
