This article outlines the formulation process of the local standard of Traditional Chinese Medicine Chronic Disease Management Guideline for Menopausal Women with Emotional Disorders(DB44/T 2547-2024;hereafter referred to as the"Guideline").By analyzing its structural framework and content,this study elucidates the TCM-specific chronic disease management strategies incorporated in the Guidelines,aiming to supply references to the development of similar standards and provide guidance for TCM chronic disease management practices.The development for the Guideline involved a multi-dimensional evidence collection process,including literature review,summary of expert experience,and expert consultations.By employing a multi-dimensional evidence-based approach,the Guideline has effectively integrated diverse evidence sources,and ensures the standard formulation being scientific and precise.The Guideline proposes the requirements for TCM-specific chronic disease management of menopausal women with emotional disorders firstly.By incorporating TCM lifestyle regulation,TCM emotional management,TCM dietary therapy,medication guidance,exercise therapies,and distinctive external treatments,the Guideline has developed into a comprehensive TCM chronic disease management system for prevention,treatment,rehabilitation and health preservation.The integrated approach effectively reduces the recurrence of emotional disorder and enhances quality of life of the patients.

Objective To investigate the effect of protocatechuic acid(PCA)on Toll-like receptor 4(TLR4)/nu-clear factor-kappa B(NF-κB)signal pathway in rats with ulcerative colitis(UC).Methods After modeling,rats were divided into control group,model group(5%trinitrobenzene sulfonic acid(TNBS)induction),low(L-PCA),middle(M-PCA),high(H-PCA)dose protocatechuic acid group(rats were given with PCA at doses of 20,40 and 80 mg/kg respectively),and intervention model group(LPS,rats were given with PCA at doses of 80 mg/kg and 0.8 mg/kg LPS solution intraperitoneally),and 12 rats in each group were given the drug continu-ously for 14 days.After treatment,rats were evaluated by disease activity index(DAI),and the morphology and apoptosis of colon were observed by hematoxylin eosin(HE)staining and TUNEL staining.The protein levels of Occludin,Zona occludens 1(ZO-1),claudin-1,Tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,IL-10,TLR4 and p-p65/p65 in colon were detected by Western blotting.The expression of TLR4 protein in colon was de-tected by immunohistochemical staining.Results Compared with control group,the colon of model group rat showed obvious injury,DAI score and positive rate of TUNEL were increased(P＜0.05),the relative protein ex-pression of TNF-α,IL-1β,TLR4 and p-p65 were increased(P＜0.05),the relative protein expression of Occlu-din,ZO-1,claudin-1 and IL-10 were decreased(P＜0.05).Compared with model group,colonic injury was allevi-ated in L-PCA,M-PCA and H-PCA groups,DAI score and positive rate of TUNEL were decreased(P＜0.05),the relative protein expression of TNF-α,IL-1β,TLR4 and p-p65 were decreased(P＜0.05),the relative protein expression of Occludin,ZO-1,claudin-1 and IL-10 were increased(P＜0.05).Compared with H-PCA group,co-lon injury was aggravated in LPS group,DAI score and positive rate of TUNEL were increased(P＜0.05),the rel-ative protein expression of TNF-α,IL-1β,TLR4 and p-p65 was increased(P＜0.05),the relative protein expres-sion of Occludin,ZO-1,claudin-1 and IL-10 was decreased(P＜0.05).Conclusions Protocatechuic acid can al-leviate TNBS-induced colon injury in UC rats,improve intestinal barrier function,and inhibit colon inflammatory response,the mechanism of which is related to the activation of TLR4/NF-κB signaling pathway.

How to improve the performance of circulating tumor DNA (ctDNA) signal acquisition and the accuracy to authenticate ultra low-frequency mutation are major challenges of minimal residual disease (MRD) detection in solid tumors. In this study, we developed a new MRD bioinformatics algorithm, namely multi-variant joint confidence analysis (MinerVa), and tested this algorithm both in contrived ctDNA standards and plasma DNA samples of patients with early non-small cell lung cancer (NSCLC). Our results showed that the specificity of multi-variant tracking of MinerVa algorithm ranged from 99.62% to 99.70%, and when tracking 30 variants, variant signals could be detected as low as 6.3 × 10 ^-5 variant abundance. Furthermore, in a cohort of 27 NSCLC patients, the specificity of ctDNA-MRD for recurrence monitoring was 100%, and the sensitivity was 78.6%. These findings indicate that the MinerVa algorithm can efficiently capture ctDNA signals in blood samples and exhibit high accuracy in MRD detection.

Many human genetic diseases, including Hutchinson-Gilford progeria syndrome (HGPS), are caused by single point mutations. HGPS is a rare disorder that causes premature aging and is usually caused by a de novo point mutation in the LMNA gene. Base editors (BEs) composed of a cytidine deaminase fused to CRISPR/Cas9 nickase are highly efficient at inducing C to T base conversions in a programmable manner and can be used to generate animal disease models with single amino-acid substitutions. Here, we generated the first HGPS monkey model by delivering a BE mRNA and guide RNA (gRNA) targeting the LMNA gene via microinjection into monkey zygotes. Five out of six newborn monkeys carried the mutation specifically at the target site. HGPS monkeys expressed the toxic form of lamin A, progerin, and recapitulated the typical HGPS phenotypes including growth retardation, bone alterations, and vascular abnormalities. Thus, this monkey model genetically and clinically mimics HGPS in humans, demonstrating that the BE system can efficiently and accurately generate patient-specific disease models in non-human primates.

Objective The purpose of this study was to compare the adenomyosis models in nude mice generated by four different methods,and to find out an optimal modeling method, and to provide an ideal animal model for exploring pathogenesis and experimental treatment of uterine adenomyosis. Methods 1. 80 female healthy nude mouse were divided randomly into 4 groups: Intraperitoneal implantation group, subcutaneous implantation group, intraperitoneal injection group, and subcutaneous injection group. The transplants were taken for pathological examination at 4 weeks after surgery. Results The success rate of intraperitoneal implantation group was 95%,and that of the subcutaneous implantation group was 45%,while the success rate of intraperitoneal injection group and subcutaneous injection group was 0%. Conclusions Establishment of a nude mouse model of uterine adenomyosis by intraperitoneal implantation method has a high success rate and with good stability, and is an ideal mouse model of human-derived uterine adenomyosis.

BACKGROUND: Osteoporosis is a serious threat to the health and quality of life in the elderly. It is important to establish an ideal experimental animal model to study the etiology and treatment of osteoporosis.OBJECTIVE: To establish a rat model of osteoporosis induced by different dosages of retinoic acid, thus selecting the optimal dosage.METHODS: Eighty female Sprague-Dawley rats were randomly divided into control, low-, middle- and high-dosage groups based on body mass (n=20 per group), The rats in the latter three groups were induced with 80, 100, and 120 mg/(kg?d) retinoic acid via gastric lavage for 14 days.RESULTS AND CONCLUSION: Compared with the control group, the bone mineral density, number of osteoblasts and osteoclasts, and bone microarchitecture in the low-dosage group showed no significant changes, while there were significant decrease in the serum level of calcium and bone mineral density of femur, significant increase in the number of osteoclasts at the femur and significant changes in the femoral microarchitecture in the middle- and high-dosage groups, especially in the middle-dose group. To conclude, 120 mg/(kg?d) retinoic acid via gastric lavage for 14 days can induce a stable osteoporosis model in rats.
