Staphylococcus aureus is a Gram-positive bacterium with strong pathogenicity. With the widespread use of antibiotics, its multi-drug resistance has gradually increased. Among them, methicillin-resistant S. aureus (MRSA) is one of the main pathogens of hospital and community infections. Antimicrobial peptides are short-chain peptides with good antibacterial effects and low drug resistance, which have been widely studied in recent years. This study summarizes the mechanism of action of antimicrobial peptides and related study on antimicrobial peptides against MRSA from different sources. It is found that the mechanisms of action of antimicrobial peptides include targeting bacterial cell membranes, bacterial cells, and bacterial cell walls, etc. Besides isolating antimicrobial peptides with anti-MRSA activity from animals, plants, and microorganisms, antimicrobial peptides can also be obtained through synthetic methods. Among them, GHa-derived peptides from animal sources, Ib-AMP4 from plant sources, Ph-SA from microbial sources, the synthetic peptide LLKLLLKLL-NH2, and so on, due to their effective antibacterial activity, rapid bactericidal speed, and low toxicity, are promising candidates for anti-MRSA drugs.

ObjectiveTo explore the regulatory effect of Ganluqingwen prescription on inflammation and immunity by observing the clinical efficacy of Ganluqingwen prescription in the treatment of community-acquired pneumonia (CAP), so as to provide a clinical basis for the treatment of CAP by traditional Chinese medicine (TCM). MethodsA randomized controlled trial was conducted by selecting patients who were diagnosed with CAP and identified as wind-heat attacking lungs in Xinjiang Uygur Autonomous Region Hospital of TCM from January 2024 to May 2024 and assigning the patients to a control group (treated by western medicine treatment) or an experimental group (treated by Ganluqingwen prescription combined with western medicine). The data of the enrolled patients before treatment, for three-day treatment, for seven-day treatment, and for 14-day treatment were collected, including basic information, medical history, pneumonia severity index (PSI) classification, and distribution and difference of laboratory and imaging information indexes. The peripheral blood specimens were collected from the patients. and the changes of inflammatory factors in peripheral blood were detected by using enzyme-linked immunosorbent assay (ELISA) reagent kits and flow-type multifactor microarrays to evaluate the clinical safety and efficacy of Ganluqingwen prescription in CAP. ResultsCompared with those in the groups before treatment, the total scores of TCM syndromes significantly decreased in both groups (P<0.05). Compared with those in the control group after treatment, the total scores of TCM syndromes decreased more significantly in the experimental group (P<0.05). Compared with the control group after treatment, the experimental group displayed a significantly reduced number of days of fever in patients (P<0.05). Compared with those in the groups before treatment, the leukocyte, neutrophil counts, C-reactive protein (CRP), procalcitonin (PCT), interleukin (IL)-6, alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr), creatine kinase (CK), and creatine kinase isoenzymes (CK-MB) in both groups decreased (P<0.05) after treatment. Compared with that in the control group after treatment, the decrease of leukocyte, neutrophil counts, CRP, PCT, IL-6, ALT, AST, Cr, CK, and CK-MB was more pronounced in the experimental group (P<0.05). Compared with those in the group before treatment, the partial pressure of carbon dioxide increased in the experimental group for 3 d of treatment (P<0.05), and the standard alkali residual, actual alkali residual, standard bicarbonate concentration, and actual bicarbonate concentration increased in the experimental group for 7 d of treatment (P<0.05). Compared with that in the group before treatment, D-dimer decreased in the control group for 7 d of treatment (P<0.05). D-dimer and activated partial thromboplastin time (APTT) decreased in the experimental group for 3 d of treatment (P<0.05), and D-dimer, fibrinogen (FIB), and APTI significantly decreased in the group for 7 d of treatment (P<0.05). Compared with the group for 3 d of treatment, the experimental group for 7 d of treatment showed decreased FIB (P<0.05). Compared with those in the groups before treatment, the levels of inflammatory factors IL-4, IL-10, and IL-13 were elevated in the peripheral blood of the two groups after treatment, and the levels of B lymphocyte chemoattractant (BLC), interferon gamma-induced protein 10 (IP-10), tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), monocyte chemoattractant protein-1 (MCP-1), CRP, IL-2, IL-6, IL-8, IL-17, IL-22, and IL-23p19 were significantly reduced (P<0.01). Compared with the control group after treatment, the experimental group exhibited more significant improvement in indexes above (P<0.01). ConclusionThe group treated by Ganluqingwen prescription combined with western medicine shows more significant effects on reducing total scores of TCM syndromes, lowering the ability of leukocyte and neutrophil counts, decreasing BLC, IP-10, TNF-α, IFN-γ, MCP-1, CRP, IL-2, IL-6, IL-8, IL-17, IL-22, and IL-23p19 in the peripheral blood of the patients, and elevating levels of IL-4, IL-10, and IL-13 than the group treated by western drugs alone.

OBJECTIVE To explore the willingness to pay (WTP) of Urumqi residents for community pharmacies’ medication guidance services and its influencing factors, so as to provide data support for the optimization of community pharmacy services and the establishment of a fee structure for medication guidance services. METHODS A stratified quota sampling method was employed to select 14 communities in Urumqi City. From April to June 2025, a combined offline and online questionnaire survey was conducted among adult residents in these communities. The contingent valuation method was used to construct three hypothetical scenarios (namely, basic, enhanced and extended services) of medication counselling in community pharmacies to assess residents’ WTP for these services. Binary Logistic regression was employed to analyze the influencing factors of WTP. RESULTS A total of 576 valid questionnaires were obtained. Under the scenarios of basic, enhanced and extended services, 38.54%, 49.65% and 67.19% of the respondents expressed WTP for the services, respectively. Occupational type, type of basic medical insurance, annual income, perception of pharmacists’ profession, and acceptance level of the service were identified as major influencing factors for WTP (P<0.05). CONCLUSIONS The willingness of residents in Urumqi to pay for medication counseling services provided by pharmacists in community pharmacies significantly increases with the enrichment of service content. It is recommended to incorporate basic medication counselling services provided by pharmacists in community pharmacies into medical insurance payment, while value-added services should be partially or fully self-paid by residents. Additionally, efforts should be made to strengthen the promotion of the professional and service value of licensed pharmacists, so as to facilitate the high-quality development of pharmaceutical care.

BACKGROUND:
The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study.
METHODS:
In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort.
RESULTS:
Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females.
CONCLUSION
These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.

Ovulatory dysfunction (OD) is one of the main causes of infertility in women of childbearing age, which not only affects their reproductive ability, but also physical and mental health. Traditional treatment strategies have limited efficacies, and the emergence of biomedicines provides a promising alternative solution via the strategies of combining engineered design with modern advanced technology. This review explores the pathophysiological characteristics and related induction mechanisms of OD, and evaluates the current cutting-edge advances in its treatments. It emphasizes the potentials of biomedicines strategies such as hydrogels, nanoparticles and extracellular vesicles in improving therapeutic precision and efficacy. By mimicking natural physiological processes, and achieving controlled drug release, these advanced drug carriers are expected to address the challenges in ovarian microenvironment reprogramming, tissue repair, and metabolic and immune regulation. Despite the promising progress, there are still challenges in terms of biomedical complexity, differences between animal models and human physiology, and the demand for intelligent drug carriers in the therapy of OD. Future researches are mainly dedicated to developing precise personalized biomedicines in OD therapy through interdisciplinary collaboration, promoting the development of reproductive regenerative medicine.

Three soil conditioners were prepared from granulated food waste and decomposed cattle manure combined with desulfurization gypsum, coal gangue, and maifanite, respectively. Field trials were conducted in the saline field growing Cabernet Sauvignon. The effects of soil conditioners on rhizospheric bacterial communities were studied, with the aim of providing a scientific basis for soil amelioration and restoration. Five treatments were designed, including the control (T1), conventional fertilization (T2), reduced chemical fertilization+organic matter-based soil conditioner with calcium additives (T3), reduced chemical fertilization+organic matter-based soil conditioner with silica additives (T4), and reduced chemical fertilization+organic matter-based soil conditioner with magnesium additives (T5), each with three replications. The results indicated that soil conditioners improved the rhizospheric nutrients, yield, and quality of grape (P<0.05), increased relative abundance of Proteobacteria by 17.32%-23.37%, decreased relative abundance of unidentified_Bacteria and Acidobacteriota by 4.22%-28.42% and 20.88%-35.81%, respectively. The bacterial community composition and diversity were different between treatments. Function analysis showed that the expression levels of the genes involved in chromosome and protein synthesis, mRNA biosynthesis, and glyoxylate and dicarboxylate metabolism were up-regulated in the treatments with soil conditioners. The correlation analysis revealed that multiple environmental factors affected the alpha diversity of rhizospheric bacterial communities, and some bacterial taxa were closely related to the grape yield and quality. It is concluded that soil conditioners can effectively alter rhizosphere nutrient levels and bacterial community structures and functions. T5 treatment outperforms other treatments in improving the physico-chemical and biological characteristics of rhizosphere, and the yield, and quality of grape. It has potential for application, and provides an important basis for development of new-type soil conditioners.

Objective:To evaluate the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on tourniquet-induced hypertension (TIH) in the patients undergoing anterior cruciate ligament reconstruction.Methods:Seventy-four patients of either sex, aged 18-60 yr, of American Society of Anesthesiologists Physical Status classification I or II, with body mass index of 18-30 kg/m 2, undergoing elective anterior cruciate ligament reconstruction under general anesthesia combined with preoperative femoral nerve block, were divided into 2 groups ( n=37 each) using a random number table method: sham stimulation group (group SS) and group taVNS. Group SS received stimulation on the ear lobe and the tail of the helix of the left ear. Group taVNS received stimulation on the cymba concha and the earlobe of the left ear. Both groups received stimulation from 1 h before induction of anesthesia until the end of the procedure (frequency of 30 Hz, pulse width of 300 μs, and amplitude of the strongest current that could be tolerated by the patient in the absence of pain). The tourniquet inflation pressure was 280 mmHg, with an inflation time of 60-90 min. Systolic blood pressure, diastolic blood pressure and heart rate were recorded before tourniquet inflation to assess the development of intraoperative TIH. The consumption of intraoperative propofol, remifentanil, nitroglycerin, esmolol, norepinephrine and atropine was recorded, and the occurrence of postoperative nausea and vomiting, skin itching and headache and dizziness was also recorded. Results:Compared with group SS, the incidence of TIH and the number of patients used nitroglycerin were significantly reduced ( P<0.05), and no significant changes were found in the other parameters in group taVNS ( P>0.05). Conclusions:taVNS can decrease the occurrence of TIH in the patients undergoing anterior cruciate ligament reconstruction.
10.Advances in treatment decision-making for extrahepatic recurrence of intrahepatic cholangiocarcinoma
Journal of Clinical Hepatology 2024;40(12):2361-2365
There has been a constant increase in the incidence rate of intrahepatic cholangiocarcinoma in China, and as a highly fatal malignancy, it often has an extremely poor prognosis. Surgical resection is the only possible way to cure this disease, but postoperative recurrence rate reaches as high as 50% — 70%. While recurrence is commonly observed in the liver, 15% — 30% of patients may experience extrahepatic recurrence. There are relatively few studies in the treatment strategies for extrahepatic recurrence, and there are still no clear guidelines for recommendation. Chemotherapy is currently the main treatment method for this disease. Studies have shown that some patients man achieve a prolonged survival time through surgical resection of extrahepatic recurrence sites, and in particular, such surgery is more feasible in patients with single focal lesion during recurrence. Nevertheless, surgery is only suitable to a small number of patients, and most patients still need to rely on systemic therapy and local treatment. Through a comprehensive analysis of related articles, this article summarizes the key influencing factors for extrahepatic recurrence, discusses the indications for surgery, and emphasizes the importance of individualized treatment strategies, in order to provide a reference for future treatment modalities.
