ObjectiveTo evaluate the antitumor activity of Periplaneta americana extract（PAE） against human-derived lung adenocarcinoma organoids（LUAD-PDOs） and to elucidate its potential mechanism based on transcriptomics. MethodsFresh tumor and adjacent normal tissues from patients with LUAD were collected to construct LUAD-PDOs and normal lung organoid（Nor-PDOs） models using 3D organoid culture technology. The effective intervention concentration of PAE was determined using the cell counting kit-8（CCK-8） assay. Experimental groups included the model group（LUAD-PDOs）， normal group， model administration group（LUAD-PDOs+PAE）， and normal administration group（Nor-PDOs+PAE）. Hematoxylin-eosin（HE） staining was used to observe the pathological structures of PDOs， immunohistochemistry（IHC） was performed to detect the expressions of the proliferation marker Ki-67 and lung adenocarcinoma differentiation markers cytokeratin-7（CK-7） and Napsin A， TUNEL staining was applied to detect cell apoptosis. RNA sequencing（RNA-Seq） was conducted to identify differentially expressed genes（DEGs）， followed by Gene Ontology（GO）， Kyoto Encyclopedia of Genes and Genomes（KEGG）， and Gene Set Enrichment Analysis（GSEA）， alongside protein-protein interaction（PPI） network analysis to screen core mechanisms. Finally， key targets were validated by integrating external database analysis with immunofluorescence（IF）. ResultsNor-PDOs and LUAD-PDOs that highly recapitulated the pathological characteristics of the primary tissues were successfully established. The CCK-8 assay determined that the effective intervention concentration of PAE was 16 g·L^-1. Morphological observation showed that Nor-PDOs exhibited lumen-forming structures， whereas LUAD-PDOs displayed dense， solid structures. CCK-8 and TUNEL assays revealed that， compared with the model group， PAE intervention inhibited the proliferation of LUAD-PDOs and promoted apoptosis in LUAD cells， while showing no significant effect on the viability of Nor-PDOs. Transcriptomic analysis identified 719 DEGs that were significantly reversed after PAE intervention（347 up-regulated and 372 down-regulated）（P<0.05）. GO enrichment analysis indicated that DEGs in the model administration group were significantly enriched in biological processes related to cell cycle regulation compared to the model group. KEGG pathway analysis revealed that PAE affected pathways related to proliferation and metabolism， including pathways in cancer and the p53 signaling pathway. GSEA further confirmed that PAE significantly enhanced the activity of the p53 signaling pathway（P<0.05）. PPI network analysis indicated that breast cancer type 1 susceptibility protein（BRCA1） and checkpoint kinase 1（CHEK1） were the core down-regulated targets in the p53 pathway. IF verified the high expression of BRCA1 and CHEK1 in LUAD-PDOs and their significant downregulation after PAE intervention（P<0.05）. Furthermore， survival analysis based on The Cancer Genome Atlas（TCGA） database indicated that low expression of BRCA1 and CHEK1 was significantly associated with prolonged overall survival in patients with LUAD（P<0.05）. ConclusionPAE effectively inhibits proliferation of LUAD-PDOs and promotes their apoptosis， its anti-tumor mechanism is potentially associated with the activation of the p53 signaling pathway， with BRCA1 and CHEK1 genes likely serving as key downstream targets for the effects of PAE.

Objective: To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences. Methods: From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience. Results: The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05). Conclusion Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

It is proposed that although allergic rhinitis manifests primarily in the nasal orifices， its root lies in deficiency of the lung and spleen and insecurity of the lung defensive qi， while deficiency of healthy qi with latent pathogen， triggering by external stimuli， and constraint of defensive yang constitute the key pathogenesis. The onset of disease is not caused solely by newly contracted external pathogens. Rather， on the basis of insecurity of the lung-defense qi， external stimuli such as wind-cold and abnormal qi， dust mites， pollen， and sudden climatic changes， activate the latent pathogen， resulting in constraint of defensive yang， disharmony between nutritive and defensive qi， impaired diffusion of lung qi， failure to contain body fluids， and dysfunction of the nasal orifices. The disease progression can be summarized as following steps， deficiency of healthy qi with latent pathogen， activation by external stimuli， constraint of defensive yang， dysfunction of the nasal orifices， incomplete elimination of the pathogen and incomplete recovery of healthy qi. The general therapeutic principle is to consolidate the defensive qi and vent the latent pathogen while regulating the lung and nasal orifices simultaneously. The empirical prescription Xingui Fangzhi Decoction （辛桂防芷汤） is used as the basic formula and modified dynamically according to the attack and remission stages. During the attack stage， treatment focuses on dispelling wind and cold， regulating defensive qi， and venting the latent pathogen； during the remission stage， it emphasizes supplementing qi， consolidating the defensive exterior， and reinforcing the spleen to resolve the latent pathogen.

Objective To evaluate the efficacy and safety of different Chinese medicine injections combined with angiotensin converting enzyme inhibitor/angiotensin Ⅱ receptor blocker(ACEI/ARB)in the treatment of proteinuria in diabetic nephropathy by using network Meta-analysis.Methods Clinical randomized controlled trials of Chinese medicine injection combined with ACEI/ARB for the treatment of proteinuria in early diabetic nephropathy were retrieved from the domestic databases such as China National Knowledge Infrastructure(CNKI),China Science and Technology Journal Database(VIP),Wanfang Data Knowledge Service Platform(Wanfang Data),and China Biology Medicine Disc(CBM),as well as from the oversea databases such as PubMed,EMbase,Web of Science,and Cochrane Library from database inception to October 2023.The Cochrane risk of bias tool ROB2.0 was used to evaluate the quality of the included literature,and traditional Meta-analysis and network Meta-analysis were performed by using R4.3.2 and Stata18.0.Results A total of 72 trials were included,involving 13 Chinese medicine injections,namely Huangqi Injection,Xuesaitong Injection,Puerarin Injection,Denzhan Xixin Injection,Breviscapin Injection,Danhong Injection,Xueshuantong Injection,Yinxingye Injection,Shuxuetong Injection,Yinxing Damo Injection,Danshen Injection,Shenkang Injection,and Danshen Ligustrazine Injection.The primary outcomes were urinary albumin excretion rate(UAER),24-hour urinary total protein(24hUTP),serum creatinine(SCr),and urine albumin-to-creatinine ratio(UACR).The results of traditional Meta-analysis showed that Chinese medicine injection combined with ACEI/ARB was more effective on reducing the levels of UAER[MD=-26.14,95%CI(-29.39,-22.89)],24hUTP[(MD=-0.22,95%CI(-0.27,-0.18)],SCr[MD=-0.34,95%CI(-0.50,-0.19)],and UACR[MD=-9.40,95%CI(-15.64,-3.16)]than ACEI/ARB alone,and the differences were all statistically significant(P<0.05).The results of network meta-analysis showed that the efficacy of Dengzhan Xixin Injection combined with ACEI/ARB was the optimum in terms of reducing UAER,Danshen Ligustrazine Injection combined with ACEI/ARB was the optimum in terms of decreasing 24hUTP,Shenkang Injection combined with ACEI/ARB was the optimum in terms of decreasing SCr,and Danhong Injection combined with ACEI/ARB had the best efficacy on improving UACR.Conclusion The efficacy and safety of Chinese medicine injection combined with ACEI/ARB in the treatment of proteinuria in early diabetic nephropathy are superior to those of ACEI/ARB alone in terms of lowering UAER,24hUTP,SCr,and UACR.However,due to the limitations of the quality and number of included literatures,the conclusions still need to be confirmed by more high-quality randomized controlled trials.

Objective:To investigate the clinical efficacy of autologous ear cartilage biomimetic nasal tip framework construction combined with dermal fat dorsal grafting in rhinoplasty.Methods:A retrospective analysis was conducted on clinical data of patients who underwent rhinoplasty at the Department of Plastic Surgery, Affiliated Hospital of Nanjing University of Chinese Medicine from June 2021 to May 2023. Autologous ear cartilage with preserved perichondrium was harvested from patients, and fashioned into a nasal tip framework simulating the natural nasal tip structure. Dermal fat grafts were harvested from the lateral gluteal crease region where the dermis was thicker, and implanted into the nasal dorsum for augmentation rhinoplasty. Postoperative follow-up included observation of incision healing, nasal tip morphology, and complications. Pre- and postoperative photographs were taken to measure nasal length and nasal tip height. Ultrasound was used to measure subcutaneous fat thickness at the nasal root before and after surgery, and absorption rates were calculated. The absorption rate at 6, 12, and 24 months postoperatively = (1 -subcutaneous fat thickness at 6 or 12 or 24 months postoperatively/subcutaneous fat thickness at 1 month postoperatively) × 100%. Aesthetic satisfaction was evaluated based on surgeon assessment, patient self-evaluation, and third-party physician evaluation (satisfaction by all three parties was rated as markedly effective, by two parties as effective, by one party as fair, and by none as poor). The aesthetic satisfaction rate = (markedly effective + effective) cases/total cases × 100%. Comparisons of preoperative and postoperative nasal tip height and nasal length were performed using paired t-tests, with P<0.05 considered statistically significant. Comparisons of subcutaneous fat thickness at the nasal root at different time points and absorption rates at different postoperative time points were performed using repeated measures ANOVA, with post-hoc pairwise comparisons using Bonferroni correction. For subcutaneous fat thickness comparisons, P<0.007 was considered statistically significant; for absorption rate comparisons, P<0.017 was considered statistically significant. Results:A total of 38 patients were included, consisting of 5 males and 33 females, with a mean age of 29.42 years (range 20-38 years). All patients were followed up for 24 months postoperatively. All incisions healed well; nasal appearance was aesthetically pleasing; nasal dorsal height was satisfactory; nasal tip mobility was good; the framework was stable; and no complications occurred. At 24 months postoperatively, nasal tip height [(22.87±0.52) mm vs. (19.94±0.53) mm] and nasal length [(47.18±0.61) mm vs. (44.20±0.55) mm] were significantly increased compared to preoperative measurements (both P<0.01). Comparison of subcutaneous fat thickness at the nasal root between preoperative and postoperative time points (1, 6, 12, and 24 months) showed statistically significant differences ( P<0.007). Post-hoc comparisons revealed statistically significant differences between: postoperative 1 month and 6 months vs. preoperative; postoperative 12 months vs. postoperative 1 and 6 months; and postoperative 24 months vs. postoperative 1 and 6 months (all P<0.007). However, the comparison between postoperative 24 months and 12 months showed no statistically significant difference ( P>0.007). Comparison of absorption rates at postoperative time points (6, 12, and 24 months) showed statistically significant differences ( P<0.017). Comparisons between postoperative 12 months vs. 6 months, and postoperative 24 months vs. 6 months showed statistically significant differences (both P<0.017), while the comparison between postoperative 24 months and 12 months showed no statistically significant difference ( P>0.017). In the aesthetic satisfaction survey, 37 cases were markedly effective and 1 case was fair, achieving an aesthetic satisfaction rate of 97%. Conclusion:The use of autologous ear cartilage for constructing a biomimetic nasal tip framework combined with dermal fat dorsal grafting in rhinoplasty results in natural postoperative appearance and high patient satisfaction, demonstrating significant value for extensive clinical use.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective To evaluate the efficacy of the manual cyclotorsion compensation method based on the obser-vation screen in the correction of with-the-rule astigmatism during small incision lenticule extraction(SMILE).Methods This prospective study enrolled 40 patients who underwent SMILE and another 40 patients who underwent Q-value-guided femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)at the Ophthalmology Center of the Second Affiliated Hospital of Nanchang University from April to September 2024.Through the random number method,one eye of each pa-tient who underwent SMILE was assigned to the manual cyclotorsion compensation group(the cyclotorsion group,40 eyes),while the contralateral eye was assigned to the non-cyclotorsion group(the non-cyclotorsion group,40 eyes).Meanwhile,one eye of each patient who underwent FS-LASIK was randomly selected for the FS-LASIK group(40 eyes).The age,uncorrected distance visual acuity(UDVA),spherical power,cylindrical power,spherical equivalent(SE),and corrected distance visual acuity(CDVA)were recorded before surgery and 3 months after surgery,respectively.Astigma-tism was subjected to Alpins vector analysis,and the indicators for assessing astigmatism included target-induced astigma-tism(TIA),surgically-induced astigmatism(SIA),difference vector(DV),correction index(CI),success index(IOS),angle of error(AE),and absolute value of angle of error(|AE|).Results Before surgery,there was no significant difference in age,spherical power,cylindrical power,SE,and CDVA among the cyclotorsion group,the non-cyclotorsion group,and the FS-LASIK group(all P＞0.05).At 3 months after surgery,the cyclotorsion group showed better UDVA and lower cylindrical power than the non-cyclotorsion group,with statistically significant differences(both P＜0.05);howev-er,there was no significant difference in CDVA,spherical power,and SE between the two groups(all P＞0.05).Besides,there was no significant difference in UDVA,CDVA,or refractive parameters between the cyclotorsion and FS-LASIK groups(all P＞0.05).The Alpins vector analysis of astigmatism 3 months after surgery revealed better SIA,CI,IOS,and|AE|in the cyclotorsion group compared with the non-cyclotorsion group,with statistically significant differences(all P＜0.05);however,there was no significant difference in TIA,DV,and AE between the two groups(all P＞0.05).No signifi-cant differences were found between the cyclotorsion and FS-LASIK groups in any astigmatism vector parameter(all P＞0.05).The linear regression analysis results indicated a high linear correlation between TIA and SIA in all groups.Conclu-sion The manual cyclotorsion compensation method based on the observation screen in the correction of with-the-rule astigmatism during SMILE is comparable to Q-value-guided FS-LASIK and superior to the conventional central tear film marking method in SMILE.

Inflammatory response is a common feature of many acute and chronic diseases,which involves in activation of various cell types.Similar to tumor cells,inflammatory response is regulated by glucose metabolic reprogramming.Cells involved in pro-inflammatory response,such as M1 macrophages,Th1 and Th17 lymphocytes,must generate energy rapidly through glycolysis transformed by glucose metabolic reprogramming to promote inflammation,while cells involved in immune regulation and anti-inflam-matory response,such as regulatory T cells and M2 macrophages,preferentially use fatty acid oxidation and oxidative phosphorylation as a main source for energy production.This article systematically reviews the role of glucose metabolic reprogramming in different stages of inflammatory response,as well as the various molecular mechanisms of glucose metabolic reprogramming in inflammatory response,including activation or inhibition of signaling pathways,epigenetic regulation,post-transcriptional regulation and post-translational modification,which aims to provide a reference for exploring the specific regulatory mechanisms of glucose metabolic reprogramming on inflammatory response and the therapeutic targets of inflammatory-related diseases.

Femoral head necrosis and fracture nonunion are common postoperative complications of femoral neck fracture. Currently, it is believed that the main causes of postoperative complications include impaired local blood supply after fracture, poor reduction quality, and inappropriate selection of internal fixation, etc. While the incidence of nonunion was significantly reduced after fracture internal fixation, the incidence of femoral head necrosis was not significantly reduced. The occurrence of complications makes it a difficult clinical decision to determine the surgical approach in the treatment of femoral neck fracture. The causes and scientific prevention and treatment strategies of postoperative complications of femoral neck fracture remain to be further studied and explored. From the perspective of leverage reconstruction balance theory and supporting stretch effect theory of proximal femoral fracture, the authors intended to analyze the causes of complications after internal fixation of femoral neck fracture and proposed scientific treatment options and an innovative internal fixation product — "dynamic compression anti-stretch nail", aiming to provide insights into effectively reducing the occurrence of postoperative complications after internal fixation of femoral neck fracture and improve its treatment strategy.
