OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） in non-small cell lung cancer （NSCLC） patients and therapeutic efficacy， with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed， Embase， Cochrane Library， CNKI， Wanfang Data， and CBM were searched from the inception to July 20， 2025. Following literature screening， data extraction and quality assessment， descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies， seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio （NLR）， derived neutrophil-to-lymphocyte ratio （dNLR）， platelet-to-lymphocyte ratio （PLR）， and monocyte-to-lymphocyte ratio （MLR）， higher lymphocyte-to-monocyte ratio （LMR） before treatment， as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR， dNLR， PLR， and interleukin-6 （IL-6）， higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate， while the association of these markers after treatment remained controversial； another study showed that an early decline in NLR， MLR， and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

Background and aims As a ferroptosis inducer, sorafenib, a first-line treatment for hepatocellular carcinoma (HCC), has a significant antitumor effect. Nonetheless, HCC patients frequently develop sorafenib resistance. Here, we investigated the impacts of progestagen-associated endometrial protein (PAEP), which controls sorafenib resistance and tumorigenesis in HCC. Furthermore, we investigated the function of PAEP and the underlying molecular mechanisms that cause HCC ferroptosis when sorafenib is applied. Methods Western blot analysis, cell proliferation, colony formation and animal experiments were performed to investigate the function of PAEP in sorafenib resistance and tumorigenesis in HCC. We detected the levels of reactive oxygen species, iron, and malondialdehyde and preformed transmission electron microscopy to investigate the relationship between PAEP and ferroptosis. Co-immunoprecipitation (co-IP) assay was performed to investigate the underlying molecular mechanisms of PAEP that cause HCC ferroptosis. Results PAEP was significantly overexpressed in HCC tissues, and this was associated with a poor clinical prognosis. PAEP silencing dramatically reduced HCC cells’ malignant phenotype. We found that sorafenib-induced ferroptosis was more sensitive to HCC cells with PAEP knockdown. Furthermore, the orthotopic cell line-derived xenograft mouse model results showed that sorafenib sensitivity can be effectively increased in vivo by PAEP knockdown. We determined that transferrin (TF) was a PAEP target using the String database, and we further supported this finding with Co-IP analysis. Additionally, on sorafenib-induced ferroptosis in HCC cells, TF partially reversed the effects of PAEP knockdown. Conclusions Our research indicates that PAEP may be a potential biomarker for predicting sorafenib resistance in HCC and disruption of PAEP expression may be a potential cancer-directed therapeutic option for HCC.

Hyperlipidemia is a common metabolic disorder driven by dysregulated lipid metabolism， whose pathological progression involves multifaceted interactions across various signaling pathways， including disrupted cholesterol homeostasis， insulin resistance， chronic inflammation， and oxidative stress. Although existing clinical medications such as statins can effectively reduce low-density lipoprotein cholesterol through single-target inhibition， significant limitations remain in comprehensively improving reverse cholesterol transport， metabolic inflammation， and coordinated regulation of glucose and lipid metabolism. Curcumin， the primary polyphenolic active compound derived from the traditional medicinal herb turmeric， exhibits multi-dimensional pharmacological effects including modulation of lipid metabolism， improvement of insulin sensitivity， suppression of inflammatory responses， and enhancement of antioxidant defense. This review systematically integrates the multi-target regulatory network of curcumin， elucidating its key mechanisms： Balancing the low density lipoprotein receptor/proprotein convertase subtilisin/kexin type 9 （LDLR/PCSK9） signaling pathway to promote reverse cholesterol transport， activating peroxisome proliferator-activated receptor α/γ （PPARα/γ） signaling pathways to coordinate glucolipid metabolic homeostasis， remodeling the gut microbiota-bile acid axis， inhibiting nuclear factor kappa-B （NF-κB）-mediated inflammatory responses， and activating the nuclear factor erythroid 2-related factor 2/antioxidant response element （Nrf2/ARE） antioxidant signaling pathway. Furthermore， supported by clinical research data， the review validates curcumin's therapeutic potential in reducing total cholesterol （TC） and triglyceride （TG） levels， increasing high-density lipoprotein cholesterol （HDL-C）， as well as improving vascular endothelial function and insulin sensitivity. The study highlights the multi-target regulatory properties of curcumin and discusses future clinical applications based on nano-delivery systems and personalized treatment strategies， providing a theoretical basis and novel insights for the prevention and treatment of hyperlipidemia and related metabolic disorders.

Objective:To analyze the clinical characteristics and treatment outcomes of children with anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibody-mediated necrotizing myopathy, and to explore early identification and management strategies to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the clinical data and treatment outcomes of 10 pediatric patients with anti-HMGCR antibody-mediated necrotizing myopathy admitted to the Department of Rheumatology, Children′s Hospital of Fudan University from December 2020 to December 2024. Statistical description was performed using SPSS 22.0.Results:Among the 10 patients, the male-to-female ratio was 1:4, the age of onset was (7.2±4.0) years, and the disease duration at diagnosis was (22.2±19.6) months. None had a history of statin exposure. Six patients presented with muscle weakness, and4 were diagnosed due to asymptomatic elevation of creatine kinase (CK); 4 had dermatomyositis-like rashes. All patients showed significantly elevated CK levels [median 3 291(1 969, 8 776)U/L] and underwent muscle biopsy. Histopathological findings revealed myofiber degeneration, necrosis, and regeneration in all cases, with inflammatory infiltration in 9 cases, MHC-Ⅰ positivity in all, and C5b-9 positivity in 9 cases. The median follow-up duration was (15.7±6.3) months. At the last follow-up, muscle strength was normal or nearly normal, and the CK median value had decreased to 977.5 (211.0, 3 536.0) U/L.Conclusion:For patients with suspected idiopathic inflammatory myopathy and significantly elevated CK, muscle-specific antibody testing-including anti-HMGCR-and muscle biopsy should be performed promptly regardless of the presence of skin rash, to ensure accurate diagnosis and guide treatment, thereby avoiding misdiagnosis or missed diagnosis.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the epidemiological and clinical characteristics of pertussis in children and the antimicrobial resistance pattern of Bordetella pertussis isolates in Anhui province in 2024. Methods:Prospective observational study. The demographic information of 4 233 cases of pertussis confirmed by nucleic acid testing in Anhui Provincial Children′s Hospital in 2024 and the clinical data of hospitalized cases were collected. The annual epidemic trend of pertussis in children, the clinical characteristics of hospitalized cases, and the vaccination status were analyzed. Bordetella pertussis isolates were recovered from nasopharyngeal swabs obtained from hospitalized children and their family caregivers during the outbreak period and antimicrobial susceptibility was tested. Results:Among the 4 233 children, 2 330 were male and 1 903 were female. A total of 4 059 cases (95.9%) occurred from March to September, with the peak of the disease from April to July (3 364 cases (79.5%)).There were 4 075 cases (96.3%) aged 9 years and under, among which 718 cases (17.0%) were under 1 year old and 2 494 cases (58.9%) were aged 4 to 7 years. During the outbreak period, there were a total of 301 hospitalized children (7.1%), with an average age of 4.4 (2.8, 16.5) months. Among them, 61 cases (20.3%) received the full course of vaccination (4 doses), 64 cases (21.3%) received partial doses of the vaccine, and 176 cases (58.5%) were unvaccinated. Among the unvaccinated children, 79.6% (172/216) were under 1 year old, 8.7% (2/23) were between 1 and 3 years old, and 3.2% (2/62) were 3 years old or older. None of the 20 cases (6.6%) of severe pertussis received pertussis vaccine.Among the 301 hospitalized children, 298 cases (99.0%) presented with typical paroxysmal spasmodic cough, 94 cases (31.2%) had vomiting after coughing, 82 cases (27.2%) had whooping sounds, and 54 cases (17.9%) had cyanotic attacks. There were 228 cases (75.7%) complicated with pneumonia and 5 cases (1.7%) with pertussis encephalopathy. The infection rate among the accompanying family members who underwent screening was 77.1% (371/481). Based on the minimum inhibitory concentration testing of 186 Bordetella pertussis isolates, the minimum inhibitory concentration 90 of azithromycin and trimethoprim-sulfamethoxazole were >256.000 and 0.050 mg/L, respectively. Conclusions:The peak of pertussis cases in Anhui region in 2024 occurred from April to July. Children aged ≤9 years were the major affected population. Infants and preschool children were most susceptible to pertussis. The intrafamily transmission rate of pertussis is high. Empirical use of macrolides for the treatment of pertussis is not recommended. Trimethoprim-sulfamethoxazole can be used as the preferred antibiotic for pertussis in children aged 2 months and above.

The quality of medical insurance settlement lists directly affects the accuracy and rationality of medical insurance payments. This study analyzed the quality problems existing in L City′s 2023 medical insurance settlement list from three dimensions: integrity, standardization and rationality, and introduced a series of medical insurance settlement list quality management measures implemented with a problem-oriented approach. City L has effectively improved the overall quality of medical insurance settlement list by compiling local medical insurance settlement list filling standards, building a closed-loop model for quality control management of medical insurance settlement lists, establishing a quality grading management system for medical insurance settlement lists, and incorporating the quality of medical insurance settlement lists into performance appraisal and agreement management. The proportion of medical insurance settlement lists with quality problems in the city decreased from 8.12% (87 500 out of 1 077 300) in 2023 to 1.80% (20 700 out of 1 152 000) in 2024. The number of problems related to integrity, standardization, and rationality decreased from 39 900, 129 300, and 105 300 to 12 600, 14 800, and 24 800, respectively. These findings could provide a reference for medical insurance settlement list quality management in other regions.

OBJECTIVE To investigate the molecular epidemiological characteristics of clinical isolates of carbapen-em-resistant Klebsiella pneumoniae(CRKP)resistant to ceftazidime/avibactam(CZA).METHODS From Jan.2022 to Dec.2023,totally 63 strains of non-repetitive CZA-resistant CRKP that were isolated for the first time from hospitalized patients of the First Affiliated Hospital of Nanchang University were enrolled in the study,and 50 strains of CZA-sensitive CRKP were randomly chosen as the research subjects.The drug susceptibility rates of the strains were observed.The drug resistance genes,virulence genes and capsular serotypes of the strains were detected by means of polymerase chain reaction(PCR).The molecular epidemiological characteristics of the strains were observed by using molecular biological techniques such as pulse field gel electrophoresis(PFGE)and multilocus sequence typing(MLST).RESULTS Among the CZA-resistant CRKP strains,45(71.43％)were iso-lated from sputum.The result of drug susceptibility testing showed that the drug resistance rates of the CZA-re-sistant strains to amikacin,aztreonam and minocycline were lower than those of the CZA-sensitive strains(P＜0.05),and the drug resistance rates of the CZA-resistant strains to tigecycline was higher than that of the CAZ-sensitive strains(P＜0.05).The carrying rates of blaKPC,blaNDM,blaSHV-1,blaTEM-1,blaCTX-M,blaqnrS,blaacc(6')-Ib and blarmtB genes of the CZA-resistant strains were relatively high.Among the detected capsular serotypes,K64(n=18,28.57％)was dominant.ST11(n=25,39.68％)was predominant strain among the CZA-resistant CRKP strains.CONCLUSIONS ST11 is dominant among the CZA-resistant CRKP strains.The strains carry with multiple drug resistance genes and virulence genes.The drug resistance rate of the CZA-resistant strains to tigecycline is higher than that of the CZA-sensitive strains,and it is necessary to attach great importance during the clinical treatment.

Objective:To investigate the effect of local food-source enteral nutrition(EN) to improve the nutritional status of stroke patients.Methods:The clinical data of 180 patients with ischemic stroke admitted to the First People′s Hospital of Chengdu and the Second People′s Hospital of Chengdu during the period from June 2021 to June 2023 were selected retrospectively, patients in both groups received EN at 24 to 48 h after admission, and total energy intake was evaluated 7 d later, which was divided into the standard calorie group (90 cases) and the low- calorie group (90 cases) according to total energy intake. The total energy intake of patients in the standard calorie group increased to 125 -146 kJ/ (kg·d) after 7 d. Patients in the low-calorie group gradually increased to 105 kJ/ (kg·d) after 7 d. The changes in inflammatory factors and nutritional indexes before and after treatment were compared between the two groups, and the incidence of malnutrition and neurological function deficit before and after treatment were compared between the two groups.Results:After treatment, the levels of serum interleukin 1β, tumor necrosis factor-α, ultrasensitive C-reactive protein in the low-calorie group were lower than those in the standard calorie group: (16.74 ± 4.33) ng/L vs. (20.15 ± 5.68) ng/L, (25.58 ± 5.09)ng/L vs. (30.04 ± 6.46) ng/L, (12.41 ± 3.29) mg/L vs.(15.24 ± 4.18) mg/L, there were statistical differences ( P<0.05); the levels of serum total protein, albumin, transferrin were higher than those in the standard calorie group: (66.42 ± 8.32) g/L vs. (60.58 ± 8.32) g/L, (46.32 ± 6.39) g/L vs. (41.42 ± 5.34) g/L, (3.44 ± 0.65) g/L vs. (3.12 ± 0.31) g/L, there were statistical differences ( P<0.05). The incidence of malnutrition in the low-calorie group was lower than that in the standard calorie group: 3.33%(3/90) vs. 12.22%(11/90), there was statistical difference ( χ2 = 9.05, P<0.05). After 1 month and 3 months of treatment, the scores of National Institute of Health stroke scale (NIHSS) scores in the low-calorie group were lower than that in the standard calorie group: (15.76 ± 3.54) scores vs. (22.34 ± 6.24) scores, (8.65 ± 2.74) scores vs. (11.76 ± 4.83) scores, there were statistical differences ( P<0.05). Conclusions:Early local food-borne EN can improve the nutritional status of stroke patients, reduce the expression of inflammatory factors, and facilitate the improvement of neurological damage.
