Dysregulated lipid metabolism can lead to multi-organ dysfunction, particularly the cardiovascular diseases. Increasing evidence indicates that lipid metabolism abnormalities also play a significant role in various ocular diseases, especially in blinding diseases such as glaucoma, age-related macular degeneration, diabetic retinopathy, and optic atrophy. Lipid dysregulation not only directly affects the structure and function of ocular tissues but also exacerbates optic nerve damage and retinal degeneration by modulating inflammation, apoptosis, and oxidative stress. This review summarizes the relationship between lipid metabolism disorders and ocular diseases, explores the pathogenic mechanisms involved in vision loss, and discusses the potential clinical applications of lipid metabolism modulation, particularly in early diagnosis, therapeutic strategies, and preventive interventions.

OBJECTIVE To assess the influence of hospital-associated carbapenem-resistant Klebsiella pneumoniae(CRKP)infection on direct economic burden of the intensive care unit(ICU)patients so as to provide bases for optimization of infection control strategies.METHODS A total of 242 patients who were detected with CRKP were chosen from 5426 patients who were hospitalized in ICUs of Fuyang People's Hospital from Jan.2021 to Dec.2024,the enrolled patients were recruited as the research subjects and were divided into the CRKP infection group with 48 cases and the non-CRKP infection group with 194 cases according to the status of hospital-associated infec-tions.The direct economic burden due to the CRKP infection was analyzed by propensity score matching(PSM)method.RESULTS The isolation rate of CRKP was 39.93％(242/606),the incidence of hospital-associat-ed infections was 0.88％(48/5426),ventilator-associated pneumonia were dominant,accounting for 43.75％.To-tally 44 pairs were matched in a 1∶1 ratio by PSM.After the matching,the median total hospitalization costs of the CRKP infection group was 226,079.17 yuan per case,more than 121,615.56 yuan per case in the non-CRKP infection group(P＜0.05).The burden of western medicine costs was the highest composition of the costs,which was increased by 39,166.45 yuan per case,and the cost of antibiotics was increased by 5251.20 yuan per case(all P＜0.05).The length of hospital stay extended by 11.00 days per case due to hospital-associated infec-tions(40.00 days vs.29.00 days,P＜0.05).CONCLUSIONS The direct economic burden of the ICU patients is re-markably increased due to the hospital-associated CRKP infection,which is mainly from the increase of west-ern medicine costs and extension of hospital stay.It is crucial to optimize the use of antibiotics and reduce the inva-sive procedures(such as removing ventilators as early as possible)so as to reduce the direct economic burden.

Metastasis remains the primary cause of cancer-related mortality worldwide. Circulating tumor cells (CTCs) represent critical targets for metastasis prevention and treatment. Traditional Chinese medicine may prevent lung cancer metastasis through long-term intervention in CTC activity. Tiao-Shen-Zhi-Ai Formular (TSZAF) represents a Chinese medicine compound prescription utilized clinically for lung cancer treatment. This study combined three principal active ingredients from TSZAF into a novel TSZAF monomer combination (TSZAF mc) to investigate its anti-metastatic effects and mechanisms. TSZAF mc demonstrated significant inhibition of proliferation, migration, and invasion in CTC-TJH-01 and LLC cells, while inducing cellular apoptosis in vitro. Moreover, TSZAF mc substantially inhibited LLC cell growth and metastasis in vivo. Mechanistically, TAZSF mc significantly suppressed the Wnt/β-catenin signaling pathway and CXCL5 expression in lung cancer cells and tissues. Additionally, TAZSF mc notably reduced neutrophil infiltration in metastatic lesions. These findings indicate that TSZAF mc inhibits lung cancer growth and metastasis by suppressing the Wnt/β-catenin signaling pathway and reducing CXCL5 secretion, thereby decreasing neutrophil recruitment and infiltration. TSZAF mc demonstrates potential as an effective therapeutic agent for lung cancer metastasis.

Based on the results of the National Drug Sampling and Inspection Programme,we summarized the history,the standard collection,the production enterprises and the dosage form specifications,the quality standard study,the pharmacological and pharmacodynamic study,and the clinical application study of Wuwei Qingzhuo preparation of Mongolian medicine and Shiliu Jianwei preparation of Zang medicine,to provide the basis for improved quality standards for both preparations.The development of these two preparations was searched and analyzed through literature.The available information shows that there is very little research on the two preparations and insufficient pharmacological experimental and clinical experimental data.The two preparations are basically the same in prescription and efficacy.However,the quality standards are very different,which are not conducive to the quality control of the two and their related dosage forms.And it is suggested that the Chinese Pharmacopoeia should take the situation of this category into comprehensive consideration,and unify the quality standards of the two preparations.
