Despite their recent deterioration, village clinics have historically been an important source of health care for the poor and elderly in rural China. In this paper, we examine the current role of village clinics, the patients who use them and some of the services they provide. We focus specifically on the role of village clinics in meeting the health-care needs of the rural poor and elderly. We find that although clinics are continuing to decline financially, they remain a source of care for the rural elderly and poor. We estimate that the elderly are 10-15 percent more likely than young individuals to seek care at a clinic. We show that clinics provide many unique services to support the rural elderly （and the elderly poor）, such as in-home patient care, the option for patients to pay on credit, and free and discounted services.

Along with rapid advances in high-throughput-sequencing technology,the development and application of molecular markers has been critical for the progress that has been made in crop breeding and genetic research.Desirable molecular markers should be able to rapidly genotype tens of thousands of breeding accessions with tens to hundreds of markers.In this study,we developed a multiplex molecular marker,the haplotype-tag polymorphism(HTP),that integrates Maize6H-60K array data from 3,587 maize inbred lines with 6,375 blocks from the recombination block map.After applying strict filtering criteria,we obtained 6,163 highly polymorphic HTPs,which were evenly distributed in the genome.Furthermore,we developed a genome-wide HTP analysis toolkit,HTPtools,which we used to establish an HTP database(HTPdb)covering the whole genomes of 3,587 maize inbred lines commonly used in breeding.A total of 172,921 non-redundant HTP allelic variations were obtained.Three major HTPtools modules combine seven algorithms(e.g.,chain Bayes probability and the heterotic-pattern prediction algorithm)and a new plotting engine named“BCplot”that enables rapid visualization of the background information of multiple backcross groups.HTPtools was designed for big-data analyses such as complex pedigree reconstruction and maize heterotic-pattern prediction.The HTP-based analytical strategy and the toolkit developed in this study are applicable for high-throughput genotyping and for genetic mapping,germplasm resource analyses,and genomics-informed breeding in maize.

Drawing on a survey of106 secondary vocational schools and 7309 students in two provinces of China, this descriptive paper assesses whether vocational schooling is measuring up to government benchmarks for quality and whether poor students are able to access quality schools. We find that secondary vocational schools have met government benchmarks for teacher qualification and training, student opportunities forpractical training and adequate facilities. Furthermore, poor students access schools of similar quality to non-poor students, even though 34percent of poor students do not receive financial aid. We conclude that recent policies are successfully ensuring secondary vocational school quality and equity of access to school quality between poor and non-poor students. However, financial aid policies should be re-examined, such that poor students receive sufficient coverage. Moreover, given that input-based measures only proxy school quality, the government should consider holding schools accountable for outcomes such as student learning.

区块链技术具有去中心化和信息难以篡改的技术特征。基于区块链技术的农产品溯源体系能有效激励农产品供应链各主体采取措施保障农产品质量安全。在加速布局追溯体系建设、优化数字化发展的环境下,中国农产品区块链溯源技术迎来重要发展机遇,涌现了一些政府主导的创新实践,但总体而言该技术应用仍处于初级阶段。本文系统地梳理了砀山酥梨、潍坊韭菜、西湖龙井茶三个实践案例,研究发现目前农产品区块链溯源技术应用仍面临溯源成本高、产品溢价难预期、利益分配机制不健全等关键挑战。为促进中国农产品区块链溯源体系建立,本文根据国内外实践经验提出以下建议:实施重点环节溯源以降低成本和优化溯源体系;提供公开透明的公众投诉渠道以提升产品溢价;采用闭环式运作且配套严格的质量安全监管制度。

Policymakers in developing countries have prioritized the mass expansion of vocational education and training(VET).This study examines whether the quality of VET in developing countries increases by investing greater resources per student.To achieve this goal,we examine the impacts of attending model schools(which have far more resources per student)on a range of student cognitive,non-cognitive,and behavioral outcomes.Using representative data from a survey of approximately 12,000 VET students from China,multivariate regression and propensity score matching analyses show that attending model vocational high schools do not benefit student outcomes,despite their substantially greater resources.

Background:Diffuse large B-cell lymphoma(DLBCL)patients refractory to rituximab-based immunochemotherapy have a dismal prognosis.However,the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries.To validate the definition and outcomes of refractory DLBCL in China,we conducted a multicenter,retrospective cohort study.Methods:The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL(REAL-TREND)study was performed using real-world data from 8 centers in China.DLBCL patients with curative intent were included in the REAL-TREND dataset.Overall survival(OS)was estimated using the Kaplan-Meier method and compared by the log-rank test.Due to heterogeneity in response rates among different centers,the response rates of refractory patients were pooled using random-effect models.Multivariate survival analysis was performed using the Cox regression model.Results:A total of 2778 DLBCL patients diagnosed between January,2010 and December,2015 were enrolled to this study.After validating previous definitions,the SCHOLAR-1 study was most suitable to define refractory DLBCL.The estimated 5-year cumulative incidence of refractory patients was 20%(95% confidence Interval[CI]=18%-22%).After the determination of refractory disease,overall response rate and complete remission rate were 30%(95%CI=22%-38%)and 9%(95%CI=4%-15%),respectively.Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months(95%CI=5.5-7.1 months)and 2-year OS rate of 16%(95%CI=12%-20%).International prognostic index score 4-5(hazard ratio[HR]=2.22;95%CI=1.47-3.35),central nervous systemrelapse(HR=1.43;95%CI=1.04-1.97),and best response status(HR=2.68;95%CI=1.42-5.03 for partial remission.HR=5.97,95%CI=3.21-11.11 for stable disease/progressive disease)were independent unfavorable prognostic factors.Conclusions:This is the first large-scale Asian cohort study focusing on outcomes of refr

The tumor suppressor protein p53 is central to cancer biology,with its pathway reactivation emerging as a promising therapeutic strategy in oncology.This study introduced LZ22,a novel compound that selectively inhibits the growth,migration,and metastasis of tumor cells expressing wild-type p53,demonstrating ineffectiveness in cells devoid of p53 or those expressing mutant p53.LZ22’s mechanism of action involves a high-affinity interaction with the histidine-96 pocket of the MDM2 protein.This interaction disrupted the MDM2-p53 binding,consequently stabilizing p53 by shielding it from proteasomal degradation.LZ22 impeded cell cycle progression and diminished cell proliferation by reinstating the p53-dependent suppression of the CDK2/Rb signaling pathway.Moreover,LZ22 alleviated the p53-dependent repression of Snail transcription factor expression and its consequent EMT,effectively reducing tumor cell migration and distal metastasis.Importantly,LZ22 administration in tumor-bearing mice did not manifest notable side effects.The findings position LZ22 as a structurally unique reactivator of p53,offering therapeutic promise for the management of human cancers with wild-type TP53.
