OBJECTIVE To study the improvement effects and potential mechanisms of water extract from Chrysanthemum morifolium on skeletal muscle atrophy in rats after ischemic stroke. METHODS Sprague-Dawley rats were randomly divided into sham operation group， model group， ATP group （10 mg/kg）， C. morifolium water extract high-dose and low-dose groups （1.08， 0.54 g/kg）. Except for sham operation group， ischemic stroke models were induced in rats from the other groups using middle cerebral artery occlusion. Starting from the first day after surgery， rats in each group were given corresponding drug/normal saline intragastrically， once a day， for consecutive 7 days. On the 7th day post-surgery， the rats’ body weights were measured， and their motor functions were evaluated， including Longa scores， exercise distance， grip strength； the electrophysiological signals of the skeletal muscles in rats were measured； the pathological morphology of the soleus muscle in rats was observed； the levels of tumor necrosis factor-α （TNF-α） in serum and soleus muscle were measured； the expressions of proteins related to TNF-α/c-Jun N- terminal kinase （JNK）/mitogen-activated protein kinase （MAPK） signaling pathway in the soleus muscle were determined. RESULTS Compared with sham operation group， the body weight， grip strength and exercise distance of rats were decreased/ shortened significantly （P＜0.01）； additionally， there was a notable reduction in the interpeak value of skeletal muscle electrophysiology （P＜0.05 or P＜0.01）. Longa score， as well as the levels of TNF-α in serum and soleus muscle， and the expression levels of TNF-α， phosphorylated JNK， phosphorylated MAPK， muscle ring-finger protein-1， and muscle atrophy Fbox- 1 protein in the soleus muscle， were all significantly elevated （P＜0.01）. The skeletal muscle cells of the soleus muscle in the model group showed significant atrophy， with a markedly decreased cross-sectional area （P＜0.01）. Compared with the model group， the levels of the aforementioned indicators were significantly reversed in C. morifolium water extract groups （P＜0.05 or P＜ 0.01）， and the skeletal muscle cells of the soleus muscle were markedly enlarged. CONCLUSIONS C. morifolium water extract can improve skeletal muscle atrophy in rats after ischemic stroke， the mechanism of which may be associated with suppressing the activation of the TNF- α/JNK/MAPK E-mail：19932015@cdutcm.edu.cn signaling pathway.

ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） triple therapy in the treatment of spontaneous bacterial peritonitis （SBP） with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients， and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group， with 43 patients in each group. Both groups received standard western medicine treatment， while the experimental group additionally received TCM triple therapy， including oral Qingre Liangxue Jiedu Decoction （清热凉血解毒汤）， retention enema with Dachengi Decoction （大承气汤）， and abdominal application of Qingre Zhitong Lishui Fomulation （清热止痛利水方） with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment， various indicators were measured， such as TCM syndrome scores， ascites volume measured by abdominal ultrasound， liver function indicators including total bilirubin （TBIL）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and albumin （ALB）， infection markers， including neutrophil percentage （NEUT%）， C-reactive protein （CRP）， and procalcitonin （PCT）， inflammatory factors， such as tumor necrosis factor-alpha （TNF-ɑ）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）， intestinal mucosal barrier function markers， including endotoxin （ET）， diamine oxidase （DAO）， D-lactic acid （D-Lac）， occludin， and zonula occludens-1 （ZO-1）， and peritoneal polymorphonuclear （PMN） cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis， with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% （38/41）， which was significantly higher than the 80.49% （33/41） in the control group （P＜0.05）. Compared with pre-treatment values， both groups showed significant reductions in TCM syndrome scores， ascites volume， TBIL， ALT， AST， NEUT%， CRP， PCT， TNF-α， IL-6， ET， DAO， D-Lac， Occludin， and ZO-1， with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment （P＜0.05）. Furthermore， the experimental group outperformed the control group in all the above indicators after treatment （P＜0.05）. The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group （P＜0.01）. There were no significant changes in routine urine and stool tests， renal function， electrolytes， or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome， alleviates liver inflammation， improves liver function， accelerates the resolution of ascites， and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

Diabetic foot is one of the common chronic complications， the most common cause of hospitalization， and even the main cause of disability and death among diabetic patients. In the process of disease occurrence， development， and treatment， patients experience complex changes in physical， psychological， and social relationships. Their understanding and practice of the disease is a constant process of construction and change， which contains strategic practices influenced by factors such as disease progression， family relationships， culture and traditions of social， and doctor-patient interactions. Based on the research concepts in the field of medical anthropology， this paper applied field research methods such as survey interviews and participatory observation， and took the rich and varied and personalized narrative of diabetic foot patients as the entry point to understand their unique and detailed disease stories， as well as focused on answering the changes in the views of illness， treatment， family， society， and the body outlook experienced by diabetic foot patients. This paper aimed to provide a new perspective for understanding this group， as well as offer valuable insights for improving their treatment and management， which will help promote the overall health and quality of life with diabetic foot patients.

Objective To investigate the current status of nurses'knowledge,attitude and practice regarding sleep management of critically ill children in pediatric ICU,and to analyze its impact factors.Methods A self-designed questionnaire on general information and a questionnaire on knowledge and practical behaviors of pediatric ICU nurses on child's sleep management were used.In March 2023,902 pediatric ICU nurses from 24 hospitals in China were surveyed using a convenient sampling method,and the impact factors were analyzed using multiple stepwise linear regression.Results 893 valid questionnaires were collected and the recovery rate of valid questionnaires was 99.00％.Nurses in pediatric ICU scored(33.71±7.76)in knowledge dimension,(37.38±4.86)in attitude dimension and(80.60±16.78)in practice dimension,with a total score of(151.78±24.27).The scores of knowledge and attitude,knowledge and practice,attitude and practice are all positively correlated(r=0.393,P＜0.001;r=0.495,P＜0.001;r=0.320,P＜0.001).The results of multiple stepwise linear regression analysis showed that gender,region,whether they had received sleep management training were the influencing factors of pediatric ICU nurses'total score of knowledge,attitude and practice towards children's sleep management(P＜0.05).Conclusion Nurses in pediatric ICU are positive about sleep management for critically ill children,but their knowledge and practice levels need to improve.Nursing managers should strengthen the theoretical knowledge and practical behavioral training of pediatric ICU nurses on child sleep management,develop scientific sleep management plans,and guide nurses to make reasonable evaluation and interventions to improve children's sleep quality.

ObjectiveTo explore the underlying mechanism by which the Chinese medicine compound Yitangkang granule（YTK） treats diabetic kidney disease （DKD） by observing its effects on podocyte autophagy through the regulation of phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/forkhead transcription factor O1 （FoxO1） signaling pathway mediated by silent information regulator 1 （SIRT1） via advanced glycation end products （AGE）/receptor for AGE （RAGE） axis. MethodNinety-six 8-week-old healthy male SPF-grade Wistar rats were selected and randomly divided into blank control group （B）， model control group， high-dose YTK （40 g·kg^-1）， medium-dose YTK （20 g·kg^-1）， low-dose YTK （10 g·kg^-1）， and Western medicine control （20 mg·kg^-1 losartan） groups. The DKD rat model was established by high-fat diet feeding combined with intraperitoneal injection of streptozotocin. After successful modeling， the rats in each group received the corresponding treatments for eight weeks. The levels of superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， and catalase （CAT） were measured according to the instructions of the respective assay kits. Hematoxylin and eosin （HE） staining was used to observe pathological changes in kidney tissues. Immunohistochemistry was employed to detect the average optical density values of α-smooth muscle actin （α-SMA）， fibronectin （FN）， desmin， and nephrin. Western blot analysis was used to measure the expression levels of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， RAGE， SIRT1， Caspase-3， and FoxO1 proteins in kidney tissues of DKD rats. ResultCompared with the blank control group， the model group showed significantly lower levels of SOD， GSH-Px， and CAT， and significantly higher levels of MDA （P<0.01）. The rats exhibited severe kidney damage. The positive expression of podocyte marker proteins α-SMA， FN， and desmin increased significantly， while nephrin and podocin significantly decreased （P<0.01）. The expression levels of PI3K， p-PI3K， Akt， p-Akt， RAGE， and Caspase-3 proteins were significantly elevated， while SIRT1 and FoxO1 protein levels were significantly reduced （P<0.01）. Compared with the model control group， rats in the YTK treatment groups showed significantly higher levels of SOD， GSH-Px， and CAT， and significantly lower levels of MDA in serum （P<0.01）. The degree of kidney damage was reduced to varying extents. The average optical density values of podocyte marker proteins α-SMA， FN， and desmin were significantly decreased， while nephrin and podocin significantly increased （P<0.01）. The expression levels of PI3K， p-PI3K， Akt， p-Akt， RAGE， and Caspase-3 in kidney tissues were significantly reduced， while SIRT1 and FoxO1 expression levels significantly increased （P<0.01）. The Chinese medicine groups demonstrated a clear dose-response trend. ConclusionYTK may alleviate kidney pathological damage， reduce proteinuria， and protect kidney function in DKD rats， thereby delaying the progression of DKD by improving podocyte autophagy through the AGE-RAGE axis-mediated SIRT1 regulation of the PI3K/Akt/FoxO1 signaling pathway. Additionally， a dose-response relationship was observed in the Chinese medicine groups.

ObjectiveTo investigate the correlation between mild cognitive impairment (MCI) and traditional Chinese medicine (TCM) body constitution types in the elderly, and to provide an evidence for the control of cognitive impairment in the elderly. MethodsThe elderly aged 65 and above who participated in the community physical examinations in a community of Changning District, Shanghai were selected as the research subjects. The cognitive function was assessed by using the Clock Drawing Test combined with the Ascertain Dementia 8-item Questionnaire (AD8), the Montreal Cognitive Assessment (MoCA) and the Mini-mental State Examination (MMSE). The diagnostic criteria for MCI was identified based on the 2018 Chinese Guidelines for the Diagnosis and Treatment of Dementia and Cognitive Disorders, along with the assessment results and clinical history information. The current investigation method was used to collect the basic information and the prevalence of chronic disease of the subjects through questionnaire inquiries. The elderly subjects’ ability to take care of themselves was evaluated based on the Elderly Self⁃Care Ability Evaluation Scale, while the TCM body constitution types were determined based on the Chinese Medicine Health Care Management Service Specification. The association of the detection rate of MCI with gender, education level, history of chronic disease and TCM body constitution types were analyzed lastly. ResultsA total of 2 351 elderly people were investigated, including 1 037 males and 1 314 females, with an average age of (74.11±6.15) years. 174 subjects, accounting for 7.40%, were identified with MCI. The highest detection rate of MCI in the elderly are those with a Qi stagnation constitution (10.8%), followed by those with a dampness-heat constitution (9.1%) and a Qi deficiency constitution (8.4%). Multivariate logistic regression analysis showed that advanced age, lower educational level, a history of tuberculosis, and TCM constitutions such as dampness-heat, Qi stagnation, and Qi deficiency were the potential risk factors for MCI. ConclusionThere is a significant association between TCM constitution types such as dampness-heat, Qi stagnation, and Qi deficiency with MCI. TCM techniques can be integrated into the health management services for the elderly population, and targeted interventions can be provided to those with imbalanced constitution types so as to reduce the risk of MCI.

Objective We aimed to assess the serum levels of the glycolysis-related protein hypoxia-inducible factor-1α(HIF-1α)and cytokines in patients with relapsing-remitting multiple sclerosis(RRMS)before and after treatment with the traditional Chinese medicine Yishen Daluo Decoction,as well as their correlation with clinical parameters,and explore the immune regulatory mechanism of Yishen Daluo Decoction on multiple sclerosis.Methods Twenty-eight patients with RRMS in remission recruited from May 2018 to January 2022 in the Multiple Sclerosis Clinic at Dongzhimen Hospital,Beijing University of Chinese Medicine were retrospectively included.Comparisons were made with paired samples from 13 of them before and after Yishen Daluo Decoction treatment.A total of 20 gender-and age-matched healthy controls(HCs)were also recruited.Clinical information was collected from all of the subjects,and the neurological impairments of RRMS patients were assessed with the Expanded Disability Status Scale(EDSS)score.ELISA and SP-X multiplex cytokine assays were used to measure the serum levels of HIF-1 α and 10 cytokines(IL-1β,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-22,IFN-γ,and TNF-α),respectively.Spearman's method was used to analyze the correlation between the serum levels of HIF-1α and cytokines,and the correlation between the serum levels of HIF-1α and cytokines and patients'clinical indicators,including disease duration,the number of attacks,and the EDSS score.Results Serum HIF-1α,IL-4,IL-6,IL-8,IL-10,IL-12p70,IFN-γ,and TNF-α levels in the RRMS group were significantly higher than those in the HC group(P＜0.05).Serum levels of HIF-1α,IL-4,IL-6,and IL-12p70 in the Yishen Daluo Decoction-pre group were significantly higher than those in the Yishen Daluo Decoction-post group(P＜0.05).In addition,the serum HIF-1α level was positively correlated with IL-6(r=0.452,P=0.016)and TNF-α(r=0.524,P=0.004)levels in patients with RRMS.The IFN-γ level was negatively correlated with the EDSS score(r=-0.423,P=0.025),the IL-4 level was negatively correlated with disease duration(r=-0.385,P=0.043),and the TNF-α level was positively correlated with disease duration(r=0.397,P=0.037).Conclusion The regulatory mechanism of Yishen Daluo Decoction on immune imbalance in RRMS may be related to its ability to reduce the serum levels of the glycolysis-related protein HIF-1α in RRMS patients.It is also related to the levels of various inflammatory cytokines.

Objective:To observe the clinical efficacy of a new type of "firebreak" drainage with skin preservation in the treatment of Fournier's gangrene.Methods:This technique is suitable for patients with perianal necrotizing fasciitis who can tolerate surgery without large area of skin blackness and necrosis. Procedure and key points: (1) The dividing line between inflammatory tissue and normal tissue was determined according to imaging examination and intraoperative exploration; (2) The abscess cavity was cut along the most obvious part of the abscess fluctuation, with a long diameter of 3~4 cm and a short diameter of 1~2 cm; (3) Necrotic tissue was discreetly separated and removed from the main incision to the outer edge of the infection. A fusiform incision was made every 3 to 5 cm, with a long diameter of 2 to 3 cm and a short diameter of 1 cm, and discreetly separated until the normal tissue, and a hose was hung between the adjacent incisions for drainage. (4) Each adjacent edge cut between the stealth separation and hanging hose drainage, forming a "firebreak"; (5) Rinse the wound repeatedly; (6) If the infection invades the rectum, colostomy is performed as required. The case data of 11 patients with perianal necrotizing fasciitis admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from July 2019 to February 2023 were retrospectively analyzed. All patients were treated with emergency surgical debridement by "firebreak" drainage with skin preservation.Results:All 11 cases were cured with 100%. One case underwent multiple operations. The hospitalization time was 11-46 days, with an average of 22 days. The wound healing time was 28-75 days, with an average of 43 days. Except for 1 patient with trauma, all the other patients had no significant anal function injury after surgery. All the 11 patients recovered and were discharged from hospital with a median follow-up of 136 (115-413) days.Conclusions:The "firebreak" drainage based on skin preservation has the advantages of less trauma and faster recovery, and do not cause obvious anal function damage.

Objective:To explore the association between self-control and the co-occurrence of depres-sive symptoms and overweight or obesity from adolescence to early adulthood in the Chinese population,and to provide a scientific basis for personalized interventions targeting individuals with different risks in the future.Methods:From a prospective cohort study that lasted for 10 years:The China family panel studies(CFPS),a total of 608 children and adolescents meeting the following inclusion and exclusion criteria were included as study subjects:(1)Aged 10 to 19 years,at normal weight according to Chinese standards,and without depressive symptom in 2010;(2)Had self-control scores,and with at least two measurements of depressive symptoms and body mass index(BMI)between 2010 and 2020;(3)The only one or the youngest child and adolescent from each family.The co-occurrence of depressive symp-toms and overweight or obesity was defined in three ways:Both of the average level of standardized scores of depressive symptoms and BMI Z-scores across multiple measurements over time were at a high level,or both of the trajectories of depressive symptoms and BMI over time based on the latent classification trajec-tory model(LCTM)belonging to the"risk-type",or individuals had depressive symptoms and over-weight/obesity at the last follow-up survey.The multinomial Logistic regression model was used to examine the association between standardized scores of self-control and the co-occurrence of depressive symptoms and overweight or obesity.Results:The score of self-control was associated with the co-occur-rence of depressive symptoms and overweight or obesity when using healthy individuals as the reference group after adjusting for age(years),gender(male/female),area(urban/rural),weekly physical ac-tivity duration(high/low),parental education level(college or above/high school or below),parental weight status(overweight or obese or not),and parental depressive symptoms(with depressive symptoms or not),regardless of the definition of the risk population.Specifically,the risk of co-occurrence of de-pressive symptoms and overweight or obesity was reduced by 33％(95％CI:14％to 48％,based on the average level across multiple measurements over time)to 78％(95％CI:6％to 95％,based on the joint trajectories of depressive symptoms and BMI over time)per 1-standard deviation(1-SD)increase in self-control score.In addition,the risk of depressive-symptom-dominant and overweight-or-obesity-dominant was reduced by 25％(95％CI:4％to 42％,only based on the average level across multiple measure-ments over time)and 21％(95％CI:1％to 37％,only based on the joint trajectories of depressive symptoms and BMI over time)per 1-SD increase in self-control score,respectively.The results from sen-sitivity analysis that defined individuals'weight status according to World Health Organization(WHO)standards were consistent with our main findings.Conclusion:Individuals with higher self-control scores from adolescence to early adulthood have a lower risk of co-occurrence of depressive symptoms and over-weight or obesity,suggesting that personalized interventions for co-occurrence of depressive symptoms and overweight or obesity can be carried out based on self-control scores in the future.

Inflammatory bowel disease(IBD)is a group of chronic non-specific intestinal inflammatory diseases with unclear etiology.Its pathogenesis may be related to the intestinal immune imbalance caused by the interaction of multiple factors such as environment,genetics and intestinal microecology.Macrophages,as an important component of the immune system,can maintain a balance between pro-inflammatory and anti-in-flammatory responses in the intestine.Macrophages can be divided into two polarization types:classical activa-tion(Ml)and alternative activation(M2)according to the different phenotypes and cytokines secreted by macrophages.The polarization of macrophages plays a key role in the subside of intestinal inflammation and the healing of mucosa.In the intestinal immune system of IBD,the imbalance between pro-inflammatory and anti-inflammatory factors caused by macrophage polarization imbalance can lead to sustained progression of intestinal mucosal inflammation and impairment of barrier function,playing a key role in IBD.The changes in macrophage polarization levels may affect the therapeutic effect of IBD.Therefore,targeting macrophage po-larization may be an important target for the treatment of IBD.This article summarizes the role of intestinal macrophage polarization in IBD and the impact of regulating macrophage polarization in IBD treatment to pro-vide reference for studying the new treatment methods for IBD.
