Objective:To explore the potential categories and influencing factors of medication compliance in patients with cardiometabolic multimorbidity, and provide a reference for formulating targeted intervention measures.Methods:A cross-sectional study design was adopted. From March to October 2024, the patients with cardiometabolic multimorbidity in the First Hospital Affiliated with Hunan Normal University (Hunan Provincial People′s Hospital) were selected by convenience sampling method as research objects. Data were collected using a general information questionnaire, Medication Adherence Rating Scale (MARS), Perceived Social Support Scale (PSSS), and Medication Literacy Questionnaire. The latent class analysis was used to explore the characteristics and classifications of medication compliance in cardiometabolic multimorbidity, and unordered multivariate Logistic regression was used to analyze the influencing factors of different latent classes.Results:A total of 421 subjects were included, consisting of 291 males and 130 females, aged (64.28±9.74) years old. The overall medication adherence score was 6.00 (5.00, 8.00) points, which could be divided into four categories: overall good adherence group (24.47%, 103/421), subjective perception-poor adherence group (15.91%, 67/421), forgetfulness-poor adherence group (37.53%, 158/421), and overall poor adherence group (22.09%, 93/421). The results showed that when taking the overall good adherence group as a reference, the inability to obtain pharmaceutical information from social media, medication literacy scores, social support scores were the influencing factors for the subjective perception-poor adherence group ( OR=4.210, 0.516, 0.733, all P<0.05). Occupational characteristics (employees in public institutions or government-affiliated institutions), age, social support scores were the influencing factors for the forgetfulness-poor adherence group( OR=0.173, 1.155, 0.781, all P<0.05). Occupational characteristics (employees in public institutions or government-affiliated institutions), failure to receive medication guidance from medical staff, medication literacy scores and social support scores were the influencing factors for the overall poor adherence group( OR values were 0.136-5.275, all P<0.05). When taking the overall poor adherence group as a reference, failure to receive medication guidance from medical staff and medication literacy scores were the influencing factors for the subjective perception-poor adherence group ( OR=0.310, 1.752, both P<0.05). Failure to receive medication guidance from medical staff, age, medication literacy scores and social support scores were the influencing factors for the forgetfulness-poor adherence group ( OR values were 0.315-2.554, all P<0.05). Conclusions:There is significant heterogeneity in medication adherence among patients with cardiometabolic multimorbidity. Healthcare professionals should consider individual characteristics in clinical practice and provide targeted, precise interventions to improve adherence in different patient categories.

Nocardia is a Gram-positive pathogen responsible for causing dairy mastitis,which leads to purulent granulomatous lesions in mammary tissue and can significantly impact the dairy indus-try,resulting in substantial economic losses.To develop a rapid and accurate diagnostic method for detecting Nocardia of bovine origin,a conserved sequence of the 16S rRNA gene from Nocardia was selected from the NCBI database.Based on this sequence,a pair of primers and a TaqMan fluo-rescent quantitative probe were designed.The validation of the TaqMan fluorescence quantitative PCR(qPCR)method found in this study showed that the Ctvalue had a good linear relationship with recombinant plasmid concentrations ranging from 1×1010 to 1×102 copies/μL,with a regres-sion equation of y=-3.536x+43.78,a correlation coefficient(R2)of 0.997 5,a slope of-3.536,and an amplification efficiency(E)of 91％(where 90％＜E＜110％).The specificity was strong,with no cross-reactions with other pathogens.The standard curve had a high sensitivity with a low-er detection limit of 1 × 102 copies/μL,it was 100-fold higher than conventional PCR.The repeatability of the standard curve was also good.Both intra-and inter-group coefficients of varia-tion were below 2％.Using this method,234 milk samples and 80 environmental samples were tested using this method,respectively,with a positive detection rate of 27.07％,whereas conven-tional PCR had a positive detection rate of 19.43％,indicating that this method was more sensitive compared to conventional PCR.The fluorescent quantitative PCR detection method established in this study provides an effective means for the clinical detection of Nocardia in dairy cows.

Objective:To summarize the current status and research hotspots in volume management among patients with heart failure, and to predict future research trends.Methods:Literature related to volume management in heart failure patients published between January 1, 2004 and August 1, 2024 was retrieved from the China National Knowledge Infrastructure and Web of Science Core Collection databases. CiteSpace software was used to perform visual analysis of publication volume, authors, institutions, countries, and keywords.Results:A total of 5 008 articles were retrieved, of which 145 were Chinese and 202 were English publications. The overall publication trend showed a steady increase over the past two decades. The most prolific author was Fudim (7 publications), the leading institution was Mayo Clinic (14 publications), and the country with the highest output was the United States (91 publications). Keyword co-occurrence, clustering, and burst detection analyses revealed that current research hotspots in both Chinese and English literature mainly focus on the management and control of volume overload, exploration of nursing strategies, and patient self-management and home-based rehabilitation. Emerging trends include out-of-hospital volume overload control and intelligent volume management technologies.Conclusions:Research on volume management in heart failure patients is evolving toward diversification and integration. Clinical interventions and standardized guidelines have gained increasing attention. Home-based volume management and overload control continue to be key areas of interest. In the future, the integration of artificial intelligence and the development of individualized home self-management programs will likely become important directions to improve the quality of life in patients with heart failure.

Objective:To conduct quality evaluation and content analysis of adult postoperative nausea and vomiting (PONV) guidelines, so as to provide reference for management of clinical PONV.Methods:Web of Science, Embase, PubMed, UpToDate, SinoMed, Wanfang Database, China National Knowledge Infrastructure, VIP, domestic and foreign clinical practice guidelines and related professional association websites were systematically searched, and the search period was from database establishment to May 6, 2022. Four researchers independently evaluated the guidelines that met the inclusion and exclusion criteria using a clinical guideline research and evaluation system, and summarized the recommendations of the guidelines.Results:Finally, a total of 15 guidelines were included in this study. The overall quality evaluation of the guide was 3 A-level recommendations and 12 B-level recommendations. The average standardization percentages for 6 areas were 81.57% for scope and purpose, 49.91% for participants, 65.38% for rigor, 89.54% for clarity, 34.86% for applicability and 55.42% for independence. A total of 18 recommendations were summarized from five aspects, such as team and organizational management, PONV risk assessment, baseline risk reduction, multimodal prevention of PONV and effectiveness evaluation and monitoring.Conclusions:The guidelines for PONV management mainly come from foreign countries. It is recommended that clinical personnel should learn from foreign guidelines and combine them with domestic clinical situations to localize the recommended opinions and guide the development of clinical practice.

Objective:To report a rare case of renal injury secondary to Strongyloides stercoralis infection, and investigate common pathological subtypes, pathogenesis and differential diagnosis of Strongyloides stercoralis infection-associated renal injury combined with literature. Methods:The pathological features of renal biopsy were analyzed by immunofloruscence, light microscope and electronic microscope. The pathological changes of digestive tract and pathogen morphology were observed through endoscope and digestive tract biopsy. The correlation between clinical-pathological features and pathological changes of kidney and digestive tract was analized.Results:The 26-year-old male patient presented with nephrotic syndrome. The pathological changes of renal biopsy were consistent with minimal change disease with interstitial focal eosinophil infiltration. Laboratory examination showed that the patient had unexplained eosinophilia and increased IgE level. Hence the patient was treated with glucocorticoid. After 2 months of therapy, proteinuria decreased and turned to negative while the patient developed progressive headache, gastrointestinal bleeding and progressive decrease of hemoglobin. Emergency gastroscopy showed extensive congestion and erosion of the stomach and duodenum. Gastric mucosal biopsy showed a large number of slender "s" shape larvae in the mucosa. The patient also had bilateral lung infection, positive Escherichia coli in cerebrospinal fluid and purplish skin rash around the umbilicus. A serious infection of Strongyloides stercoralis was diagnosed. After antibiotics and anthelmintic treatment, gastrointestinal symptoms and headache disappeared, and no parasite was found in endoscopy. No recurrence of nephrotic syndrome was found during 2 years of follow-up. Conclusions:Strongyloides stercoralis infection might first present with nephrotic syndrome with handful hints of digestive tract combined with eosinophilia and increased IgE levels. Therefore, in epidemic areas or patients with suspicious exposure history, it is necessary to exclude Strongyloides stercoralis infection before immunosuppressive therapy to avoid fatal complications.

Objective:To explore the effect of smoking on the wound healing of stage 4 pressure ulcers in rats.Methods:Fifty male Sprague-Dawley rats aged 6-8 weeks were divided into simple pressure ulcer group and smoking+ pressure ulcer group according to the random number table, with 25 rats in each group. After the rats in the smoking+ pressure ulcer group received passive smoking intervention for 12 weeks, an iron plate was placed in the back muscle of each rat in 2 groups, and a magnet was placed outside the skin at the corresponding position of the iron plate for 2 h at each time, with 5 times a day and continuously for 6 days to reproduce stage 4 pressure ulcer model. Immediately after establishing the model, 3 rats in each group were sacrificed and wound tissue was collected, and hematoxylin-eosin staining was applied to observe the pathological changes of the wounds. On 1, 3, 7, and 14 day (s) after establishing the model, 3 rats in each group were collected to measure the pressure ulcer wound area by the paper jam method. After measurement of the wound area, the rats were sacrificed and the wound tissue was collected, and the protein expression levels of matrix metalloproteinases 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) in wound tissue were detected by immunohistochemical method, and the ratio of MMP-9/TIMP-1 was calculated.The wound healing time of the remaining 10 rats in each group was recorded. Data were statistically analyzed with analysis of variance for factorial design, two independent sample t test, and Bonferroni correction. Results:(1) Immediately after establishing the model, muscle fiber necrosis and dissolution with large areas were seen on the wound, the myofibrils arranged loosely, and more lymphocytes and monocytes infiltration were seen around the wound of rats in simple pressure ulcer group. A large number of necrotic myofibers were dissolved and gradually disappeared, the myofibrils arranged loosely, and the number of diffuse lymphocytes and monocyte infiltration in wound of rats in smoking+ pressure ulcer group were significantly higher than those in simple pressure ulcer group. (2) The wound areas of rats in smoking+ pressure ulcer group were significantly larger than those in simple pressure ulcer group on 1, 3, 7, and 14 day (s) after establishing the model ( t=3.019, 2.549, 2.181, 3.674, P<0.05 or P<0.01). (3) On 1 to 14 days after establishing the model, the protein expression levels of MMP-9 and TIMP-1 in the wound tissue and the ratio of MMP-9/TIMP-1 of rats in the two groups increased first and then decreased. On 1, 3, 7, and 14 day (s) after establishing the model, the protein expression levels of MMP-9 in the wound tissue and the ratio of MMP-9/TIMP-1 of rats in smoking+ pressure ulcer group were significantly higher than those in simple pressure ulcer group ( t=4.783, 4.508, 6.325, 7.204, 3.078, 2.989, 4.081, 4.696, P<0.05 or P<0.01), and the protein expression levels of TIMP-1 in wound tissue of rats in the two groups were similar. (4) The wound healing time of rats in smoking+ pressure ulcer group was (48.9±2.6) d, which was significantly longer than (35.2±2.3) d of simple pressure ulcer group ( t=12.477, P<0.05). Conclusions:Smoking can up-regulate the expression of MMP-9 in pressure ulcer wound and result in an imbalance of MMP-9/TIMP-1, thereby affecting the wound healing of stage 4 pressure ulcers in rats.

The high morbidity and mortality of non-small cell lung cancer (NSCLC) did influence the quality of life of tumor patients world-wide. There is an urgent need to develop new therapies that have high anti-tumor activity and low toxicity side effects. It is widely accepted that autophagy can play diverse roles in carcinogenesis, such as induces pro-death of lung cancer cells or helps the escape from cell death, making it become a proper anticancer target. It's believed that various monomers of Chinese traditional medicine closely correlates to anti-NSCLC activities, and that even could affect the acquired multiple drug resistance (MDR). Furthermore, autophagy might be the underling mechanisms which could play a role as the candidate targets of natural active compounds. Recent studies of terpenoids, alkaloid, dietary polyphenols, saponins and other active ingredients that extracted from a large variety of herbs suggest that different monomer compounds could either regulate the activity of pro-death autophagy or influence the level of protective autophagy of NSCLC cells, thus changing their drug sensitivity and cell viability. This paper aims to give a systemic description of the latest advances about natural compounds and their derivatives that involved in tumorigenesis of NSCLC via inducing the autophagy.
