Clinical Study on External Use of Chinese Medicine in Treating Children with Herpetic Stomatitis

Background: Pediatric herpetic stomatitis is a common pediatric disease, the course of the disease is about 1 - 2 weeks, and it usually occurs in 1 - 3 years old children, due to infection of herpes simplex virus I and onset. Objective: To observe the curative effect of Chinese medicine prescription (Yueshi, Zhongbai, Qingdai, Phelloderma phelloderma and glycyrrhiza) on children with herpetic stomatitis. Methods: 90 patients were divided into 2 groups by random number table method. 45 patients in the observation group were treated with traditional Chinese medicine, and 45 patients in the control group were treated with iodine glycerin. The total effective rate after treatment was compared between the two groups. Results: The total effective rate of the treatment group was 95.55%;the total effective rate of the control group was 71.11%;the total effective rate of the two groups after treatment was compared;the treatment group was significantly better than the control group;the difference was significant (P 0.05). Conclusion: The external use of Chinese medicine in the treatment of pediatric herpetic stomatitis has achieved good results, improving the condition of children, and significantly improving the clinical efficacy.

我国小学人员经费比例变动及影响因素分析

教育是人力资本密集型事业,教师是最重要的教育生产要素,人员经费在教育经费支出中占支配性地位。20世纪末以来,我国小学人员经费比例经历了一个先上升后下降的过程。与国际水平相比,我国小学人员经费比例远远偏低。各省份小学人员经费比例差异很大,且在2002年后一直扩大。与一般模式不同,我国各省份小学人员经费比例高低没有受到教育发展水平的影响。教育经费的充裕程度、教育质量和财政自主性,是显著影响各省份小学人员经费比例的重要因素。应该将以人为本的理念落实到教育经费的配置上,提高小学的人员经费比例和教师薪酬,在优化支出结构的基础上提高教育经费的使用效率。

Association oftransforming growth factor-β1 gene variants with risk of coal workers'pneumoconiosis

Objective： The aim of this case-control study was to explore whether five tagging single nucleotide poly- morphisms （tSNPs） within the transforming growth factor-ill （TGF-fll） gene were involved in manifestation of inflammatory and fibrotic processes associated with coal workers pneumoconiosis （CWP）. Methods： The study included 508 CWP patients and 526 controls who were underground coal miners from Xuzhou Mining Business Group. Five tSNPs were selected from the HapMap and detected by polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP） method. Results： The single SNP analysis showed that the genotype frequencies of SNP2 （rs1800470, ＋869T/C, extron 1） and SNP5 （rs11466345, intron 5） in CWP cases were significantly different from those in controls. Multivariate logistic regression analysis revealed that SNP2 （rs1800470） CC genotype was associated with decreased risk of CWP （OR = 0.50, 95% CI = 0.32-0.78）, which was evident among subgroups of those never smoke （OR = 0.40, 95%CI = 0.24-0.66）, cases with stage Ⅱ（OR = 0.41, 95%CI = 0.22-0.76） and exposure period （〈 28 y： OR = 0.54, 95%CI = 0.31-0.95; ≥ 28 y： OR = 0.52, 95%CI = 0.32-0.96）. However, the SNP5 （rs11466345） GG genotype was associated with an increased risk of CWP （OR = 2.5, 95%CI = 1.36-4.57）, and further stratification analysis showed that the risk of CWP was increased in both smoking and nonsmoking groups, shorter and longer exposure groups, while the risk of CWP was only increased in patients with stage I and Ⅱ. Conclusion： This study suggests that TGF-β1 polymorphisms may contribute to susceptibility of CWP.

Single crystal metal-organic framework constructed by vertically self-pillared nanosheets and its derivative for oriented lithium plating

This vertically self‐pillared(VSP)structure extends the application range of traditional porous materials with facile mass/ion transport and enhanced reaction kinetics.Here,we prepare a single crystal metal‐organic framework(MOF),employing the ZIF‐67 structure as a proof of concept,which is constructed by vertically self‐pillared nanosheets(VSP‐MOF).We further converted VSP‐MOF into VSP‐cobalt sulfide(VSP‐CoS2)through a sulfidation process.Catalysis plays an important role in almost all battery technologies;for metallic batteries,lithium anodes exhibit a high theoretical specific capacity,low density,and low redox potential.However,during the half‐cell reaction(Li++e=Li),uncontrolled dendritic Li penetrates the separator and solid electrolyte interphase layer.When employed as a composite scaffold for lithium metal deposition,there are many advantage to using this framework:1)the VSP‐CoS2 substrate provides a high specific surface area to dissipate the ion flux and mass transfer and acts as a pre‐catalyst,2)the catalytic Co center favors the charge transfer process and preferentially binds the Li+with the enhanced electrical fields,and 3)the VSP structure guides the metallic propagation along the nanosheet 2D orientation without the protrusive dendrites.All these features enable the VSP structure in metallic batteries with encouraging performances.

An Analysis of the Consumer Demand Structure of Rural Residents in Chongqing City in the Context of New Urbanization

Using ELES model and econometric methods,in the context of new urbanization,we use the time series data on the consumer spending of rural residents in Chongqing City to perform an empirical analysis of the consumer demand structure of rural residents,reveal the characteristics,differences and changes concerning the consumption structure of rural residents in Chongqing City,and set forth some policy recommendations such as carrying out the new rural construction,optimizing the consumption structure,establishing sound social security system and income growth mechanism,and stabilizing the price level.
