Objective To determine the prognostic biomarkers and new therapeutic targets of the lung adenocarcinoma (LUAD), based on which to establish a prediction model for the survival of LUAD patients. Methods An integrative analysis was conducted on gene expression and clinicopathologic data of LUAD, which were obtained from the UCSC database. Subsequently, various methods, including screening of differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Set Enrichment Analysis (GSEA), were employed to analyze the data. Cox regression and least absolute shrinkage and selection operator (LASSO) regression were used to establish an assessment model. Based on this model, we constructed a nomogram to predict the probable survival of LUAD patients at different time points (1-year, 2-year, 3-year, 5-year, and 10-year). Finally, we evaluated the predictive ability of our model using Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves. The validation group further verified the prognostic value of the model. Results The different-grade pathological subtypes' DEGs were mainly enriched in biological processes such as metabolism of xenobiotics by cytochrome P450, natural killer cell-mediated cytotoxicity, antigen processing and presentation, and regulation of enzyme activity, which were closely related to tumor development. Through Cox regression and LASSO regression, we constructed a reliable prediction model consisting of a five-gene panel (MELTF, MAGEA1, FGF19, DKK4, C14ORF105). The model demonstrated excellent specificity and sensitivity in ROC curves, with an area under the curve (AUC) of 0.675. The time-dependent ROC analysis revealed AUC values of 0.893, 0.713, and 0.632 for 1-year, 3-year, and 5-year survival, respectively. The advantage of the model was also verified in the validation group. Additionally, we developed a nomogram that accurately predicted survival, as demonstrated by calibration curves and C-index. Conclusion We have developed a prognostic prediction model for LUAD consisting of five genes. This novel approach offers clinical practitioners a personalized tool for making informed decisions regarding the prognosis of their patients.

Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

The inflammatory effect of dietary is strongly related to the development of cancer,therefore,the diet-related inflammatory index was developed as a methodological tool to investigate the relationship between dietary,inflammation and tumors.In this paper,we summarized the results on diet-related inflammatory indices and common cancers of the digestive system based on relevant cancer epidemiological studies.The available epidemiological evidence suggests that pro-inflammatory diet is associated with an increased risk of gastrointestinal malignancies,with the strongest association with colorectal cancer,followed by esophageal and gastric cancers,and then pancreatic cancer,and the least evidence of studies with liver cancer.Among these studies,the level of evidence for esophageal cancer is lower than colorectal cancer,the study of gastric cancer has gender differences and problems in adjusting for confounders,and the study of pancreatic cancer has heterogeneous results.In view of the current research progress and deficiencies,prospective studies or population-based cohort studies,as well as strengthening nutritional epidemiological studies related to common tumors such as liver cancer could be considered in the future.This review is expecting to provide basic information and scientific basis for strengthening the related healthy eating behavior promotion in the prevention and control of digestive system tumors.

Objective:To compare the precision and stability of handheld full-course visual navigation and robot-assisted total hip arthroplasty (THA), as well as to evaluate perioperative laboratory indicators and clinical efficacy.Methods:A retrospective analysis was performed on 68 patients with unilateral hip joint disorders who underwent primary THA at the General Hospital of the People's Liberation Army of China from January to June 2024. Patients were divided into two groups based on the assistance method: the Visual Treatment Solution (VTS) group, which included 34 patients (13 males, 21 females; mean age 56.92±8.31 years; body mass index[BMI] 24.20±3.55 kg/m 2), and the MAKO group, also with 34 patients (18 males, 16 females; mean age 57.97±6.54 years; BMI 25.20±3.91 kg/m 2). Among the VTS group, 1 there were 18 cases on the left side and 16 cases on the right side, including 14 cases of femoral head necrosis, 8 cases of congenital hip dysplasia, and 12 cases of hip osteoarthritis. In the MAKO group, there were 19 cases on the left side and 15 cases on the right side, including 13 cases of femoral head necrosis, 10 cases of congenital hip dysplasia, and 11 cases of hip osteoarthritis. Preoperative planning, intraoperative verification deviations, postoperative acetabular prosthesis anteversion and abduction angles, and limb length discrepancies were analyzed. Acetabular angle distribution scatter plots were generated for intraoperative verification and postoperative imaging. The operation time, hospital stay, and laboratory values, including hemoglobin (Hb) loss, fibrinogen degradation products (FDP), D-dimer, high-sensitivity C-reactive protein (hCRP), as well as postoperative pain (measured by the visual analogue scale, VAS), hip Harris score (HHS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded. Results:No statistically significant differences were observed between postoperative imaging measurements of anteversion and abduction angles and intraoperative verification values ( P>0.05). Postoperative imaging indicated that 91% (31/34) of the VTS group and 100% (34/34) of the MAKO group were within the Lewinnek safety zone. The scatter distribution of angles in the MAKO group was more concentrated than that in the VTS group. Furthermore, the angle deviation between intraoperative verification and preoperative planning was significantly greater in the VTS group for both anteversion (2.00° [-1.00°, 4.00°] vs. 0.00° [-1.00°, 1.00°]) and abduction angles (-1.00° [-5.00°, 0.00°] vs. 0.00° [-1.00°, 1.00°]; P<0.05). The bilateral limb length discrepancies were 1.35(0.67, 2.45) mm in the VTS group and 1.65(0.50, 2.52) mm in the MAKO group, with no significant difference noted ( P>0.05). Both methods achieved effective hip biomechanical reconstruction. Additionally, no significant differences in operation time, Hb loss, FDP, D-dimer, hCRP, or postoperative hospital stay were found ( P>0.05). Follow-up at one and three months postoperatively showed no significant differences in VAS (2.94±0.92 vs. 2.97±0.83), HHS (69.88±4.20 vs. 70.06±3.88), or WOMAC scores (22.44±3.15 vs. 22.76±3.39) between the two groups ( P>0.05). Conclusion:The stability of preoperative planning and design in robot-assisted total hip arthroplasty is superior to that of handheld navigation methods. Nevertheless, both approaches demonstrate comparable postoperative prosthesis stability, laboratory indicators, and clinical outcomes.

Objective To investigate the intervention effect and mechanism of sinomenine(SIN)on Parkinson's disease(PD)mice based on GSK3 β/Nrf2/HO-1 and NF-κ B signaling pathways.Methods C57BL/6 mice were randomly divided into 6 groups:normal group,model group,positive drug group(Levodopa,75 mg?kg-1)and SIN low-,medium-and high-dose groups(20,40,80 mg?kg-1),with 8 mice in each group.Mice were intraperitoneally injected with 20 mg?kg-1 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)once a day for 5 days.Intragastric administration was performed 1 hour after injection of MPTP,once a day for 12 days.On the day 11 of administration,the mice were subjected to a pole-climbing experiment,and on the day 12,a rotating rod experiment was performed to test the behavioral changes of the mice.The levels of serum tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and IL-6 were detected by ELISA.The mRNA expression levels of TNF-α,IL-1β and IL-6 in brain tissue were detected by RT-qPCR.The protein expression levels of TH,Nrf2,HO-1,p-GSK3β,GSK3β,p-IκB,IκB,p-NF-κB and NF-κB in brain tissue were detected by Western Blot.Results Compared with the normal group,the automatic turning latency(T-turn)of the model group was significantly prolonged(P＜0.05),and the number of falls was significantly increased(P＜0.001).The expression level of TH protein in brain tissue was significantly decreased(P＜0.01),and the mRNA expression levels of IL-1β,TNF-α and IL-6 were significantly increased(P＜0.001).The serum levels of TNF-α,IL-1β and IL-6 were significantly increased(P＜0.05,P＜0.01).The protein expression levels of p-GSK3β/GSK3β,Nrf2 and HO-1 in brain tissue were significantly decreased(P＜0.05,P＜0.001),and the protein expression ratios of p-IκB/IκB and p-NF-κB/NF-κB were significantly increased(P＜0.001).Compared with the model group,the T-turn in the Sin medium-and high-dose groups was significantly shortened(P＜0.05,P＜0.001),the falling latency was significantly prolonged(P＜0.05,P＜0.01),the times of falls was significantly reduced(P＜0.001),the expression level of TH protein in brain tissue was significantly increased(P＜0.01,P＜0.001),and the level of serum TNF-α was significantly decreased(P＜0.05).The mRNA expression levels of IL-1β,TNF-α and IL-6 in brain tissue of mice in each administration group were significantly decreased(P＜0.001),the serum levels of IL-1β and IL-6 were significantly decreased(P＜0.01,P＜0.001),the protein expression levels of p-GSK3β/GSK3β,Nrf2 and HO-1 in brain tissue were significantly increased(P＜0.05,P＜0.01,P＜0.001),and the protein expression ratios of p-IκB/IκB and p-NF-κB/NF-κB were significantly decreased(P＜0.001).Conclusion SIN can enhance anti-oxidative stress and inhibit neuroinflammation by regulating GSK3β/Nrf2/HO-1 and NF-κB pathways in the brain of Parkinson's disease mice,thereby exerting neuroprotective effects.

Invasive fungal infections threaten the lives and health of humans, especially immunodeficient patients or hospitalized patients with serious underlying diseases, and impose a heavy economic burden on society. The emergence of drug-resistant fungi, the formation of biofilms, and the limits and side effects of existing antifungal drugs increase the difficulty of clinical treatment, and there is an urgent need for the development of novel antifungal drugs. Therefore, based on previous kinase chemical library antifungal activity screening studies, this paper further investigates the activity of anaplastic lymphoma kinase (ALK) inhibitor 3-[5-chloro-2-({2-methoxy-4-[4-(4-methylpiperazin-1-yl)hexahydropyridin-1-yl]phenyl}amino)pyrimidin-4-yl]-1H-indole (HG-14-10-04, HG) against various fungi and elucidates its mechanism of action. The in vitro antifungal activity of HG was evaluated by micro liquid-dilution method, time-killing curve, mycelium formation and biofilm formation assays. The results showed that HG exhibited inhibitory and even fungicidal effects against sensitive and resistant Candida albicans, Candida krusei, Cryptococcus neoformans, Candida tropicalis, Candida glabrata and Candida parapsilosis (MICs = 8-16 μg·mL^-1); HG significantly inhibited the mycelium and biofilm formation, and destroyed the mature biofilm; and it exhibited synergistic antifungal effects with amphotericin B. The antifungal mechanism of HG was investigated by flow cytometry and transmission electron microscopy, etc. Sequencing analysis showed a total of 1 041 differentially expressed genes, of which 666 were up-regulated and 375 were down-regulated. According to the GO functional classification results, the up-regulated genes were mainly involved in ribosome production, oxidation-reduction and other functions, while the down-regulated genes were mainly involved in the synthesis of carbohydrate, glycoproteins, glycolipids and their metabolism, GPI anchor synthesis, and cytoskeleton and other functions. In addition, HG could significantly increase the level of reactive oxygen species (ROS), induce the fungal necrosis, block the cell cycle at the G0/G1 phase, and change the ultrastructure of the fungi, especially the structure of the fungal cell wall. Therefore, the enhanced inhibitory and fungicidal activity of HG may be related to the elevation of ROS, alteration of cellular ultrastructure (especially cell wall structure) and cell cycle arrest at the G0/G1 phase. Further optimization of its structure will provide a basis for the discovery of novel antifungal drugs or lead compounds.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.
