Objective:To comprehensively analyze the current situation of the policy tools for primary healthcare medication continuity and security in China,and to provide advice for improving the policy system of primary healthcare medication continuity and security.Methods:Based on the theory of policy tools,a two-dimensional analysis framework of"policy tools-policy goals"was constructed.Results:A total of 407 policy text codes were generated from 58 policy texts included in the analysis.Among them,the supply-based policy tools were the most(41.03%),followed by environmental(37.59%)and demand-based(21.38%);the policy goals mainly focused on promoting the equipment and linkage of medication(21.84%),optimizing the types of medication(18.88%),and improving the centralized supply and distribution of medication(18.25%).Conclusions:Significant regional disparities exist in the design and implementation of China's primary healthcare medication continuity and security policies.Certain policy tools are absent,policy objectives lack comprehensive coverage,and coordination remains inadequate.It is suggested to optimize regional policy layouts through differentiated configuration and cross-regional coordination,enhance policy adaptability by refining policy tool combinations,strengthen weak segments and vertical coordination,promote the articulation of primary healthcare medication based on tight medical consortium,and finally build a systematic and dynamically adaptive primary healthcare medication continuity and security policy system.

This study was aimed at predicting the biological function of Streptococcus suis serotype 2(S.suis 2)tyrosine kinase Cps2C through bioinformatics and analyzing its effects on S.suis 2 pathogenicity.Online bioinformatics tools were used to analyze and predict the localization,conserved domains,transmembrane domains,protein similarity,and protein three-di-mensional structure of Cps2C.A BALB/c mouse infection model was used to compare and analyze clinical characteristics,mor-tality rates,and blood bacterial loads in mice infected with the wild-type strain 05ZYH33 and the cps2C gene knockout strainΔcps2C.Additionally,heart,brain,and joint tissue sections from infected mice were stained with hematoxylin and eosin(HE)for comparative pathological analysis.The Cps2C protein-coding gene is located upstream of the capsule biosynthesis locus cps,lacks transmembrane domains,is a homologous protein to Streptococcus pneumoniae tyrosine kinase CpsD with a 64％amino acid sequence similarity,and is potentially involved in bacterial capsule synthesis regulation.Cps2C deficiency significantly de-creased the pathogenicity of S.suis 2 in mice(P＜0.05).Compared with the wild-type strain,the Δcps2C strain showed a sig-nificantly lower blood bacterial load(P＜0.000 1).Heart,brain,and joint tissues of mice infected intraperitoneally with strains 05ZYH33 and Δcps2C remained structurally intact without e-dema,hemorrhage,or inflammatory cell infiltration;moreo-ver,characteristic lesion features of endocarditis,meningitis,or arthritis were absent.Streptococcus suis serotype 2 tyrosine kinase Cps2C may be an important regulatory factor in capsule biosynthesis,and its deficiency decreases bacterial blood survival capability and pathogenicity in mice.

This article aims to provide a good experimental method for the study of drug treatment of ulcerative colitis. According to the characteristics of ulcerative colitis's clinical symptoms, common ulcerative colitis animal models were analyzed. Based on the characteristics of clinical symptoms of traditional Chinese medicine and Western medicine for ulcerative colitis disease, the existing commonly used animal models of ulcerative colitis were analyzed to summarize the current matching degree, advantages and disadvantages of the exi-sting animal models of ulcerative colitis and clinical symptoms. At present, studies on ulcerative colitis mainly adopt four types of induction modeling methods, such as immunization, chemical stimulation, compound method and gene model. There are many reported methods of colitis modeling, but no model can reflect the characteristics of clinical symptoms of ulcerative colitis treated with Western or Chinese medicine. This article summarizes the characteristics, clinically relevant symptoms and applicable scope of immunization, chemical stimulation, compound method, and gene model, so as to provide a reliable animal model for subsequent studies of prevention and treatment of colitis.

ObjectiveTo explore the association between telomere length of leukocytes and chronic heart failure （CHF）. MethodsA total of 224 patients were recruited in this study. The patients were divided into non-CHF （Non-CHF） group （involving 117 patients） and CHF group （involving 107 patients） according to left ventricular ejection fraction. Telomere length of peripheral blood leukocytes was measured by real-time fluorescence quantitative polynucleotide chain reaction （qPCR）. Telomere length of leukocytes was compared between Non-CHF group and CHF group. Binary Logistic regression model was used to analyze the association between telomere length and CHF. ResultsTelomere length in Non-CHF patients and CHF patients was 0.9（0.64~1.18）， 0.7（0.53~0.89）， respectively. Telomere length was shorter in CHF patients than in Non-CHF patients （P<0.001）. Further results showed that telomere length was associated with CHF ［OR=0.17， 95% CI was （0.07， 0.40）， P<0.05］. After adjusting confounding factors， telomere length was still associated with CHF ［OR=0.14， 95% CI was （ 0.05， 0.33）， P<0.05］. ConclusionThe results show that telomere length of peripheral blood leukocytes is independently associated with CHF.

Hereditary gingival fibromatosis (HGF) is a familial hereditary disease; while it is rare and usually benign, it is also characterized by the slow and progressive development of gingival tissue. This paper reports on the clinical examina-tion and history of HGF in a family of patients.
