Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Kv1.3,a voltage-gated potassium channel,is highly expressed in T lymphocytes,the nervous system,and vascular smooth muscle cells.It plays a critical role in membrane excitability and electrical signal transduction,serving as an important target for studying T-cell function and providing a promising direction for developing therapeutics against autoimmune and inflammatory diseases.Therefore,the de-velopment of specific inhibitors of Kv1.3 channel has emerged as a novel therapeutic strategy for these disorders.In this study,we isolated and purified a novel Kv1.3-inhibitory peptide toxin,LmKTx13,from the venom of the scorpion Lychas mucronatus using reversed-phase high-performance liquid chroma-tography(RP-HPLC).LmKTx13 consists of 38 amino acid residues,including six cysteines that form three disulfide bonds.Whole-cell patch-clamp recordings revealed that LmKTx13 potently inhibited Kv1.3 with an IC50 of 7.92±3.0 nmol/L.Selectivity analysis showed that 2 μmol/L LmKTx13 also in-hibited Kv1.2 and Kv1.7,but exhibited no significant effects on other potassium channel subtypes or voltage-gated sodium channels.Further investigation into the mechanism demonstrated that LmKTx13 acts as a pore-blocking inhibitor of Kv1.3.By analyzing the effects of LmKTx13 on Kv1.3 channel gating ki-netics and performing sequence alignment of the pore regions of Kv1.3 and Kv1.5,we constructed site-directed mutants and identified the pore region of Kv1.3 as the critical binding site for LmKTx13.Key residues involved in the interaction included T425,G427,and H451.In summary,we discovered a no-vel pore-blocking Kv1.3 inhibitor,LmKTx13,from L.mucronatus venom,which exhibits high affinity and selectivity for Kv1.3.These findings highlight its potential as a potential lead molecule for developing Kv1.3-targeted therapeutics.

Sheep and goats are important tuberculosis hosts found predominantly in plateau and mountainous regions.In recent years,the number of reported tuberculosis cases in sheep and goats has increased.The tuberculosis pathogen can spread among vari-ous animal species and even infect humans,thus further complicating disease prevention and control,and posing a serious threat to the health of both humans and livestock.This article summarizes the global prevalence of tuberculosis in sheep and goats,and specifi-cally analyzes the epidemic status in China.Frequently used tuberculosis detection methods in sheep and goats are described,and the shortcomings of each method are briefly introduced.Additionally,on the basis of frequently applied methods for monitoring,handling,and controlling tuberculosis in sheep and goats worldwide,suggestions are offered to provide a reference for tuberculosis control in sheep and goats in China.

Objective To search,evaluate and summarise the best evidence on non-drug intervention for nipple pain or injury in breastfeeding mothers.Methods Based on the"6S pyramid"evidence model,desktop searches were conducted on databases of UpToDate,Joanna Briggs Institute evidence-based practice database(JBI),National Guideline Clearinghouse(NGC),National Institute for health and Care Excellence(NICE),Guidelines International Network(GIN),Registered Nurses'Association of Ontario(RNAO),American College of Obstetricians and Gynecologists(ACOG),Medlive,Chinese Medical Association(CMA)website,Breastfeeding Medical Association(BMA),CNKI,Wanfang Data,SinoMed,Cochrance Library,PubMed,Embase,Web of Science,and CINAHL for literature in non-drug interventions for nipple pain or injury in breastfeeding women.The literature included clinical guidelines,decisions,recommended practices,evidence summaries,expert consensus,systematic reviews and randomized controlled trials(RCTs).The searched databases spanned from 1st January,2013 to 30th April,2024.Two researchers who were trained in evidence-based nursing independently evaluated the methodological quality,extracted and integrated evidence from eligible literature.Results A total of 15 documents were included,consisting of 5 clinical guidelines,2 clinical decisions,1 expert consensus,6 systematic evaluations and 1 RCT.Thirty-one pieces of evidence were summarised across 4 categories:accurate perinatal assessment,feeding guidance,non-drug intervention and health education.Conclusion The summarised best evidence on non-drug intervention for nipple pain or injury in breastfeeding women provides an evidence-based basis for clinical healthcare professionals.

This study was aimed at investigating the infection status of orf virus(ORFV)and the genetic evolution characteristics of epidemic ORFV isolates from Anhui province.A total of 303 clinical samples collected from major meat sheep breeding cities in An-hui during 2021-2023 were subjected to ORFV detection with fluorescence quantitative PCR(qPCR).The full-length B2L and F1L genes of ORFV in the positive samples were amplified through conventional PCR and sequenced.Genetic evolution analysis of the B2L and F1L genes was conducted after sequencing.The qPCR results indicated a total ORFV positivity rate in the clinical samples of 48.8%(148/303).Multiple sequence comparisons indicated that the B2L genes of 56 sample isolates shared 96.7%-100.0%DNA and 97.4%-100.0%amino acid sequence identity.Moreover,the F2L genes of 56 sample isolates shared 95.1%-100.0%DNA and 95.0%-100.0%amino acid sequence identity.The genetic evolution tree constructed with the B2L gene DNA sequences indicated sample iso-lates and 21 reference strains located in subgroup 1,and 26 sheep-derived sample isolates and 17 reference strains located in sub-group 2.Among them,the goat-derived sample isolate FY-TYA was located in the same sub-branch as the human-derived reference strain Gansu,whereas the goat-derived sample isolate FY-XQC was located in the same sub-branch as the reference strains China Vaccine and OV-HLJ-04.The genetic evolution tree constructed with the F1L gene DNA sequences showed,the goat sample isolates FY-XQA and FY-XQC were located in the same sub-branch as the sheep-derived reference strain Xinjiang.ORFV infection was rela-tively widespread in the major meat sheep breeding areas of Anhui province,and the DNA and amino acid sequences of the B2L and F1L genes of current circulating ORFV isolates showed different degrees of genetic variation,among which F1L gene had a high de-gree of variation.Furthermore,some goat-derived sample isolates were closely related to human,vaccine,and sheep-derived refer-ence strains.These results may serve as a reference for the prevention and control of ORFV infection in Anhui province.

In 2015,the International Ascites Club proposed a new definition of hepatorenal syndrome-acute kidney injury based on the progression of hepatorenal syndrome,and studies are still being conducted to explore the exact pathogenesis of hepatorenal syndrome-acute kidney injury.Intestinal barrier plays an important bridging role in liver-kidney connection,and intestinal flora disturbance,bacterial translocation,and endotoxins entering the blood cause damage to the kidneys by releasing proinflammatory cytokines and activating immune-related cells.The entrance of bile acid into the circulation system also directly or indirectly lead to the development and progression of hepatorenal syndrome-acute kidney injury.This article reviews the crosstalk mechanism of hepatorenal syndrome-acute kidney injury from the perspective of the intestinal barrier and further clarifies the key role of the liver-gut-kidney axis in the pathogenesis of this disease,in order to provide new treatment ideas.
