Objective To investigate the predictive value of preoperative combined detection of neutrophil-to-lymphocyte ratio (NLR) and prothrombin time-international normalized ratio to albumin ratio (PTAR) for early abdominal infection after liver transplantation. Methods Clinical data of 287 recipients who underwent liver transplantation at the Liver Transplant Center of Beijing Friendship Hospital, Affiliated to Capital Medical University, from January 2020 to April 2024 were retrospectively analyzed. The patients were divided into infection group (n=60) and non-infection group (n=227) based on whether abdominal infection occurred within 30 days after surgery. The distribution characteristics of pathogens and infection time in infected patients were analyzed. Spearman correlation analysis was used to assess the correlation between NLR, PTAR, Child-Pugh score and preoperative model for end-stage liver disease (MELD) score. Univariate and multivariate logistic regression analyses were performed to identify risk factors for abdominal infection. Receiver operating characteristic (ROC) curves were plotted for NLR, PTAR, and the combined prediction model to evaluate their predictive efficacy for abdominal infection after liver transplantation. Based on the cutoff value of the combined model, recipients were divided into low-risk and high-risk groups, and Kaplan-Meier analysis was used to compare the cumulative incidence of abdominal infection within 30 days after surgery between the two groups. Results Among the 287 recipients who underwent liver transplantation, 60 developed bacterial or fungal abdominal infections postoperatively. A total of 86 strains were isolated from infected patients, with Gram-negative bacteria accounting for 58%, Gram-positive bacteria for 36%, and fungi for 5%. Preoperative NLR and PTAR were positively correlated with Child-Pugh and MELD scores (all 1 > r > 0, P < 0.05). Logistic regression analysis showed that preoperative NLR, preoperative PTAR, postoperative ICU stay duration and postoperative biliary leakage were risk factors for abdominal infection within 30 days after surgery. The area under the curve (AUC) for NLR, PTAR, Child-Pugh score and MELD score were 0.771, 0.735, 0.650 and 0.741, respectively. The AUC for the combined NLR and PTAR prediction model was 0.824 (95% confidence interval: 0.763-0.885, P < 0.001), with a cutoff value of 0.168. Kaplan-Meier analysis showed that the cumulative incidence of abdominal infection within 30 days after surgery was lower in the low-risk group than in the high-risk group, with statistically significant difference (P < 0.001). Conclusions Preoperative NLR and PTAR are independent risk factors for abdominal infection within 30 days after liver transplantation. The combined prediction model of NLR and PTAR may effectively identify high-risk recipients for early abdominal infection after liver transplantation, providing basis for early intervention.

OBJECTIVES:
To investigate the effect of curcumin on lipid metabolism in non-small cell lung cancer (NSCLC) and its molecular mechanism.
METHODS:
The inhibitory effect of curcumin (0-70 μmol/L) on proliferation of A549 and H1299 cells was assessed using MTT assay, and 20 and 40 μmol/L curcumin was used in the subsequent experiments. The effect of curcumin on lipid metabolism was evaluated using cellular uptake assay, wound healing assay, triglyceride (TG)/free fatty acid (NEFA) measurements, and Oil Red O staining. Western blotting was performed to detect the expressions of PGC-1α, PPAR-α, and HIF-1α in curcumin-treated cells. Network pharmacology was used to predict the metabolic pathways, and the results were validated by Western blotting. In a nude mouse model bearing A549 cell xenograft, the effects of curcumin (20 mg/kg) on tumor growth and lipid metabolism were assessed by measuring tumor weight and observing the changes in intracellular lipid droplets.
RESULTS:
Curcumin concentration-dependently inhibited the proliferation of A549 and H1299 cells and significantly reduced TG and NEFA levels and intracellular lipid droplets. Western blotting revealed that curcumin significantly upregulated PGC-1α and PPAR‑α expressions in the cells. KEGG pathway enrichment analysis predicted significant involvement of the HIF-1 signaling pathway in curcumin-treated NSCLC, suggesting a potential interaction between HIF-1α and PPAR‑α. Western blotting confirmed that curcumin downregulated the expression of HIF-1α. In the tumor-bearing mice, curcumin treatment caused significant reduction of the tumor weight and the number of lipid droplets in the tumor cells.
CONCLUSIONS
Curcumin inhibits NSCLC cell proliferation and lipid metabolism by downregulating the HIF-1α pathway.

The morbidity of scoliosis in adolescents in China is about 3%-5%, 80%-85% of the patients are adolescent idiopathic scoliosis (AIS), whose etiology is unknown. Scoliosis is a structural spine disease occurring during puberty or before skeletal maturation. Scoliosis has a greatly negative impacton not only the growth and development of adolescent spine, but also the mental health of adolescents. Ocular disease is a common clinical disease in which the eye ball and its accessory structures have structural abnormalitiesordys function. Ocular disease snotonly bring in convenience to patients's life, but also may induce diseases in other organs. Recent studies have shown that various ocular diseases may have a potential impact on scoliosis, and quite a fewof patients with certain ocular diseases have higher incidence rate of scoliosis. Therefore, in this article, the etiological relationship between eye diseases and scoliosis will be summarized, which provides guidance and direction for the etiological research of scoliosis and eye diseases. After sorting out, we found that the relationship between ophthalmic diseases and scoliosis mainly concentrated in the following four aspects: choroidal thickness and scoliosis, Goldenhar syndrome, gene level and strabismus. Among them, the genetic relationship is the most complex, about 40 kinds of gene or chromosome abnormalities have been found to cause ocular diseases and scoliosis; Goldenhar syndrome, also known as oculo-auriculo-vertebral spectrum, first revealed the relationship between ocular diseases and scoliosis, but the current statistical relationship is still very vague. There are few studies on choroidal thickness and strabismus at home and abroad, which are statistical studies, only revealing the relationship between choroidal thickness and scoliosis, and there are many defects in the study of choroidal thickness, which need further research.

Objective To analyze the age difference of gram negative isolates(GNB)from blood culture and antibiotic resistance profile between children and adults. Methods Age difference of pathogen distribution of GNB isolated from blood culture during 2015-2017 were retrospectively analyzed. WHONET 5.6 and Graphpad Prism 6 were used to perform Chi-square test on the pathogen proportion and antibiotic resistance rate. Results A total of 20 145 bacterial strains were isolated in Chongqing from 2015 to 2017. The top three strains of GNB were E. coli(56.7%, 6 688/11 799), K. pneumoniae(19.6%, 2 308/11 799), and P. aeruginosa(4.4%, 522/11 799). The resistant rate of E. coli to carbapenems was less than 1%. The resistant rate of K. pneumoniae to carbapenems was about 5%, while the resistant rate of S. marcescens was approximately 9%, similar to E. cloacae. The overall resistance rates of E. coli from adult patients to most antiobiotic agents were significantly higher than those of children, but the overall resistance rate of K. pneumoniae from children was higher than those of adults. The drug resistance rate of A. baumannii was higher than P. aeruginosa. A. baumannii isolates from adult patients were highly resistant to all drugs tested and more resistant than those from pediatric patients. Conclusions Majority of GNB strains isolated from blood culture were E. coli and K. pneumoniae, for which carbapenems are still active. More attention should be paid to carbapenem-resistant K. pneumoniae from children and A. baumannii from adults. National surveillance of nosocomial bloodstream infection should be highly evaluated.
