Objective To explore the correlation between lymph node metastasis and clinicopathological features of lung adenocarcinoma with diameter≤3 cm. Methods The clinicopathologic data of the patients with lung adenocarcinoma≤3 cm in diameter were retrospectively analyzed. The relationship between lymph node metastasis and age, gender, smoking history, pathological subtype, tumor diameter, pleural invasion, vascular invasion and other factors was analyzed. The risk factors of lymph node metastasis were analyzed by univariate and multivariate logistic regression. Results Finally 1 718 patients were collected, including 697 males and 1 021 females with an average age of (58.89±9.85) years. The total lymph node metastasis rate was 12.9%, among whom 452 patients of adenocarcinoma in situ and minimally invasive adenocarcinoma did not have lymph node metastasis, and the lymph node metastasis rate of invasive lung adenocarcinoma was 17.5%. Multivariate analysis showed that tumor diameter, micropapillary subtype, solid subtype, micropapillary component, solid component, vascular invasion and pleural invasion were independent risk factors for lymph node metastasis of invasive lung adenocarcinoma with diameter≤3 cm (P<0.05). While age, lepidic subtype and lepidic component were independent protective factors for lymph node metastasis (P<0.05). Conclusion Clinicopathological features can help predict lymph node metastasis of lung adenocarcinoma with diameter≤3 cm.

ObjectiveThis study employed the scoping review method to systematically retrieve and analyze the basic information and clinical research evidence of expensive Chinese patent medicines （CPMs）， aiming to provide a basis for future related research and clinical applications. MethodsEight Chinese and English databases were systematically searched for the clinical research evidence on expensive CPMs. ResultsEleven expensive CPMs （Angong Niuhuang Wan， Jufang Zhibao Wan， Suhexiang Wan， Pien Tze Huang， Niuhuang Qingxin Wan， Qinggong Shoutao Wan， Compound Realgar Natural Indigo Tablets， Xihuang Wan， Dingkun Wan， Babao Wan， and Guilingji Capsules） were selected. A total of 365 related studies were included in this review， comprising 331 clinical studies （of which 291 were randomized controlled trials）， 30 systematic reviews and Meta-analyses， 3 expert consensus， and 1 rapid health technology assessment. Among the 11 CPMs， 2（Angong Niuhuang Wan and Jufang Zhibao Wan） had a daily price over 500 yuan. The famous and precious Chinese medicinal materials involved included Moschus （frequency of 7）， Bovisc Alculus （7）， and Borneol （5）. The dosage forms included pills， capsules， oral liquid， tablets， and lozenges. The diseases treated by these CPMs mainly included malignant tumors， cerebrovascular diseases， gynecological diseases， and hepatobiliary system diseases. The sample sizes of the clinical studies were mainly concentrated within the range of 51-100 cases， and the main control form was CPM + basic Western medicine treatment vs. basic Western medicine treatment. The 331 clinical studies reported a total of 44 adverse events occurred， of which 36 were determined to be adverse reactions. ConclusionThe scarcity of raw materials leads to the high prices of expensive CPMs. The difficulty of conducting clinical research and the critical and severe cases treated lead to a lack of clinical research evidence with large sample sizes. The uneven distribution of existing studies， incomplete information on medicine package， and non-standard clinical research designs remain to be addressed in the future.

Objective To investigate the trends in the global burden due to cystic echinococcosis from 1990 to 2021, and to predict the global burden of cystic echinococcosis from 2022 to 2035, so as to provide insights into formulation of the cystic echinococcosis control strategy. Methods The global age-standardized prevalence, mortality, disability-adjusted life years (DALYs) rates and their 95% uncertainty intervals (UI) of cystic echinococcosis from 1990 to 2021 were captured from the Global Burden of Disease Study 2021 (GBD 2021) database, and the trends in the global burden of cystic echinococcosis from 1990 to 2021 were analyzed using the Joinpoint regression model. The associations between the global burden of cystic echinococcosis and socio-demographic index (SDI) were examined using a smoothing spline model and frontier analysis, and the global burden of cystic echinococcosis was projected from 2022 to 2035 using the Bayesian age-period-cohort (BAPC) model. Results The global agestandardized prevalence, mortality and DALYs rates of cystic echinococcosis were 7.69/10⁵ [95% UI: (6.27/10⁵, 9.51/10⁵)], 0.02/10⁵ [95% UI: (0.01/10⁵, 0.02/10⁵)], and 1.32/10⁵ [95% UI: (0.99/10⁵, 1.69/10⁵)] in 2021. The global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a rise by 0.14% per year from 1990 to 2021, and the global age-standardized mortality and DALYs rates of cystic echinococcosis appeared a tendency towards a decline by 4.68% and 4.01% per year from 1990 to 2021, respectively. Joinpoint regression analysis showed that global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a decline from 1990 to 2000 [annual percent change (APC) = −0.66%, 95% confidence interval (CI): (−0.70%, −0.61%)] and from 2005 to 2015 [APC = −0.88%, 95% CI: (−0.93%, −0.82%)], and towards a rise from 2000 to 2005 [APC = 3.68%, 95% CI: (3.49%, 3.87%)] and from 2015 to 2021 [APC=0.30%, 95%CI: (0.19%, 0.40%)].Theagestandardized prevalence (r = −0.17, P < 0.05), mortality (r = −0.67, P < 0.05) and DALYs rates of cystic echinococcosis (r = −0.60, P < 0.05) all correlated negatively with SDI across 21 geographical regions from 1990 to 2021, and the age-standardized mortality (r = −0.61, P < 0.05) and DALYs rates (r = −0.44, P < 0.05) both correlated negatively with SDI across 204 countries and territories in 2021. Frontier analysis revealed that the age-standardized DALYs rate of cystic echinococcosis was still not in line with the frontier in some high-SDI countries or territories. In addition, the global age-standardized prevalence was projected with the BAPC model to appear a tendency towards a rise among both men [estimated annual percent change (EAPC) = 0.18%, 95% CI: (0.13%, 0.23%)] and women [EAPC = 0.29%, 95% CI: (0.24%, 0.34%)] from 2022 to 2035, and the global age-standardized mortality [men: EAPC = −4.71%, 95% CI: (−4.71%, −4.37%); women: EAPC = −4.74%, 95% CI: (−4.74%, −4.74%)] and DALYs rates [men: EAPC = −3.35%, 95% CI: (−3.36%, −3.34%); women: EAPC = −3.17%, 95% CI: (−3.18%, −3.16%)] were projected to appear a tendency towards a decline among both men and women. Conclusions The global burden of cystic echinococcosis appeared an overall tendency towards a decline from 1990 to 2021; however, the global prevalence of cystic echinococcosis is projected to appear a tendency towards a rise from 2022 to 2035. Intensified cystic echinococcosis control programmes are recommended.

OBJECTIVES: To explore the molecular mechanism by which lncRNA SNHG15 regulates proliferation, invasion and migration of lung adenocarcinoma cells. METHODS: The lncRNA microarray chip dataset GSE196584 and LncBase were used to predict the lncRNAs that interact with miR-30b-3p, and their association with patient prognosis were investigated using online databases, after which lncRNA nucleolar RNA host gene 15 (SNHG15) was selected for further analysis. The subcellular localization of lncRNA SNHG15 and its expression levels in normal human lung epithelial cells and lung adenocarcinoma cell lines were detected using fluorescence in situ hybridization and qRT-PCR. In cultured A549 cells, the changes in cell proliferation, migration, and invasion following transfection with a SNHG15 knockdown plasmid (sh-SNHG15), a miR-30b-3p inhibitor, or their co-transfection were assessed with EdU, wound healing, and Transwell assays. Bioinformatics analyses were used to predict the regulatory relationship between lncRNA SNHG15 and COX6B1, and the results were verified using Western blotting and rescue experiments in A549 cells transfected with sh-SNHG15, a COX6B1-overexpressing plasmid, or both. RESULTS: LncRNA SNHG15 was shown to target miR-30b-3p, and the former was highly expressed in lung adenocarcinoma, and associated with a poor patient prognosis. LncRNA SNHG15 was localized in the cytoplasm and expressed at higher levels in A549 and NCI-H1299 cells than in BEAS-2B cells. In A549 cells, lncRNA SNHG15 knockdown significantly inhibited cell migration, invasion and proliferation, and these changes were reversed by miR-30b-3p inhibitor. A regulatory relationship was found between lncRNA SNHG15 and COX6B1, and their expression levels were positively correlated (r=0.128, P=0.003). MiR-30b-3p knockdown obviously decreased COX6B1 expression in A549 cells, and COX6B1 overexpression rescued the cells from the inhibitory effects of lncRNA-SNHG15 knockdown. CONCLUSIONS LncRNA SNHG15 may compete with COX6B1 to bind miR-30b-3p through a ceRNA mechanism to affect proliferation, migration, and invasion of lung adenocarcinoma cells.

Objective:To improve the understanding of patients with diffuse large B-cell lymphoma (DLBCL) with pulmonary cryptococcosis.Methods:The clinical data of 1 DLBCL patient with pulmonary cryptococcosis in the Central Hospital of Fengxian District of Shanghai in May 2023 were retrospectively analyzed, and the relevant literatures were reviewed.Results:This 75-year-old female patient was asymptomatic after 2 cycles of R-CHOP chemotherapy. The high-resolution CT of lung showed that lung nodules were progressively enlarged. Antibacterial treatment was ineffective. Pulmonary cryptococcosis was confirmed by bronchoalveolar lavage fluid (BALF) targeted high-throughput sequencing (tNGS) and cryptococcus capsular antigen (CrAg) detection. The central nervous system was not involved. And the long-term adequate-dose fluconazole was prescribed for 6 months, and the treatment against lymphoma was given synchronously. The lung nodule lesions reduced after antifungal therapy for 1 month. The lung nodules disappeared after the follow-up of 6 months after completion of final chemotherapy. The evaluation of lymphoma indicated complete remission.Conclusions:Pulmonary cryptococcosis occurs insidiously and shows no specific symptoms; its imaging manifestations are variable and routine anti-infection is ineffective. Immunochemotherapy for lymphoma patients is a high-risk factor for cryptococcal infection. tNGS and CrAg testing for BALF are effective methods of the confirmed diagnosis. The early and long-term adequate-dose antifungal treatment is the key to preventing the recurrence or progression.

OBJECTIVE: To investigate the clinical manifestations and genetic characteristics of a child with glycogen storage disease type III (GSD-III) complicated with Guillain-Barré syndrome (GBS) caused by AGL gene variants, and to analyze the pathogenesis, potential correlation, treatment and prognosis of the two diseases. METHODS: A child with GSD-III who visited the General Hospital of Ningxia Medical University due to "limb weakness for more than ten days" in July 2024 was selected as the study subject. Clinical data of the child were collected. Peripheral blood samples of the child and his parents were collected for whole exome sequencing and Sanger sequencing. Candidate variants were verified, and pathogenicity analysis was conducted for the variant sites. This study was approved by the Medical Ethics Committee of General Hospital of Ningxia Medical University (Ethics No.: KYLL-2025-1984). RESULTS: The child has presented with inability to stand or walk independently, difficulty in grasping, accompanied by numbness and pain at the distal end, choking when drinking water, occasional non-projectile vomiting, and enlargement of liver and spleen. Laboratory tests showed abnormal liver function and a significant increase in creatine kinase. Color Doppler ultrasound of the heart showed an enlarged left atrium and mild regurgitation of mitral and tricuspid valves. Genetic testing confirmed that he has harbored compound heterozygous variants of the AGL gene, namely c.1611G>A (p.E537E) and c.579del (p.W194Gfs*7), which were inherited from his father and mother, respectively. According to the guidelines from the American Collage for Medical Genetics and Genomics (ACMG), the two variants were respectively predicted as variant of unknown significance (PM2_Supporting+PM3+PP3_Supporting) and likely pathogenic (PVS1+PM2_Supporting). Electrophysiological examination confirmed that the child had severe damage to the motor and sensory nerves accompanied by axonal injury, which was consistent with the axonal variant type of GBS -acute motor and sensory axonal neuropathy. After a clear diagnosis, the child was treated with intravenous human immunoglobulin. His condition deteriorated progressively, presenting with breathing difficulties, liver failure, and gastrointestinal bleeding, and eventually deceased due to multiple organ failures. CONCLUSION The etiology of GSD-III and GBS involves multiple aspects such as genetics, metabolism and immunity. In clinical practice, it should be noted that similar clinical manifestations may occur in both conditions. Close attention should be paid to the patients' blood glucose, blood gas, coagulation function and liver function, etc. Clinical intervention should be carried out as early as possible to improve the prognosis.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Objective To investigate the role and potential mechanisms of tumor necrosis factor alpha-inducible protein 8-like molecule 1(TNFAIP8L1)in acute liver injury in mice.Methods The second generation of C57BL/6J male wild-type(WT)mice and the C57BL/6J female TNFAIP8L1+/-mice and WT mice were selected to further self-breed the third generation of male TNFAIP8L1-/-mice and the third generation of WT male mice.Five normal third-generation male WT mice and five normal third-generation male TNFAIP8L1-/-mice were selected.The serum alanine aminotransferase(ALT)levels of the two types of normal mice were measured and compared.The infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of normal mice were observed after hematoxylin & eosin(HE)staining.Flow cytometry was used to detect the percentages of neutrophils(Neu),eosinophils(EOS),dendritic cells(DC),bone marrow-derived macrophages(BMDMs),and bone marrow-derived mononuclear cell(BMNCs)in the liver myeloid cell subsets of the two types of normal mice.Another 5 third-generation male WT mice and 4 third-generation male TNFAIP8L1-/-mice were selected to induce acute liver injury mouse models using lipopolysaccharide(LPS)/D-galactosamine(D-Gal).After 24 hours,the serum ALT levels of the two types of acute liver injury mice were detected and compared,the infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of acute liver injury mice were observed,and the percentages of Neu,EOS,DC,BMDMs and BMNCs in the liver myeloid cell subsets of the two types of acute liver injury mice were measured by using the above methods.Results There was no significant difference in the percentages of Neu,EOS,DC,BMDMs and BMNCs,and serum ALT levels in the livermyeloid cell subsets of normal WT mice and TNFAIP8L1-/-mice(P＞0.05).HE staining results of liver tissues in normal WT mice and TNFAIP8L1/mice showed that hepatic lobules were structurally complete and clear,hepatocytes were morphologically normal and arranged neatly,and there was no obvious inflammatory cell infiltration or cell necrosis.Twenty-four hours after acute liver injury,the percentages of Neu and BMNCs in the liver myeloid cell subsets and the serum ALT levels in the liver tissues of TNFAIP8L1-/-mice were significantly higher than those of WT mice(P＜0.05);there was no significant difference in the percentages of EOS,DC and BMDMs in the liver myeloid cell subsets of mice between the two groups(P＞0.05).In the liver tissues of WT mice with acute liver injury,hepatic lobules were structurally blurred,hepatocytes were swollen with scattered vacuolated steatosis,and a small amount of inflammatory cells were infiltrated.In the liver tissues of TNFAIP8L1/mice with acute liver injury,hepatic lobules were structurally non-existent,and hepatocytes were severely damaged and extensively necrotic,with a large amount of inflammatory cell infiltration.Conclusion The deficiency of the TNFAIP8L1 gene in mice does not affect the development of liver myeloid cells and the homeostasis of the liver.TNFAIP8L1 plays an inhibitory role in the occurrence and development of acute liver injury.TNFAIP8L1 gene deficiency aggravates LPS/D-Gal-induced acute liver injury,possibly by increasing Neu and BMNCs infiltration and recruiting other types of immune cells to infiltrate liver tissues,thereby exacerbating liver cell necrosis.

Objective:To screen differentially expressed circular RNA (circRNA) in rat articular chondrocyte injury induced by T-2 toxin, and explore the mechanism of cartilage injury.Methods:Twenty-four SD rats (males, body weight 60 - 80 g) were randomly divided into T-2 toxin group (administrated T-2 toxin 100 ng·g -1·d -1 by gavage) and control group (administrated equal amounts of deionized water by gavage) using a random number table method, 12 rats in each group. After 4 weeks of intervention, the articular cartilage was collected for transcriptome sequencing. Deseq2 software [ P < 0.05 and |log 2(fold change)| > 1, fold change was the multiple of differential expression] was used to identify differentially expressed circRNA. Based on the competing endogenous RNAs (ceRNA) hypothesis, the miRanda software was used to predict the microRNA (miRNA, miR) binding sites of differentially expressed circRNA, and Cytoscape 3.10.0 software was used to plot the circRNA-miRNA interaction network. MiRWalk 3.0, MiRDB, and miRTarBase softwares were used to predict downstream target genes, and Cytoscape 3.10.0 software was used to map the circRNA-miRNA-mRNA interaction network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the biological functions and enrichment pathways of target genes. Results:A total of 19 differentially expressed circRNAs were screened (including 10 upregulated and 9 downregulated). A total of 1 320 miRNAs binding sites and 16 target genes were predicted. Target gene enrichment analysis revealed significant enrichment of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling pathway ( P < 0.05). Tumour necrosis factor receptor-associated factor 6 (Traf6) and interleukin-1 receptor-associated kinase 1 (Irak1) were enriched in the MAPK and NF-κB signaling pathways, with corresponding miRNA and circRNA of miR-146a-5p and chr2: 94716330|94720889. Conclusion:Nineteen differentially expressed circRNAs in rat articular chondrocyte injury are successfully screened, and chr2: 94716330|94720889 may regulate the MAPK and NF-κB signaling pathways through the miR-146a-5p/Traf6/Irak1 axis, inducing articular chondrocyte injury.

Objective To explore the relationship between preoperative coronary angiography and postoperative acute kidney injury (AKI) in cardiac surgery. Methods The clinical data of patients who underwent coronary angiography within 30 days before cardiac surgery in the First Affiliated Hospital of Xi’an Jiaotong University from January 2015 to April 2019 were retrospectively analyzed. Univariate analysis and multivariate logistic regression analyses were used to explore the relationship between the interval from preoperative coronary angiography to cardiac surgery and postoperative AKI. Results Finally 1 112 patients were collected, including 700 males and 412 females, with a median age of 61 (55, 66) years. The incidence of postoperative AKI was 40.8% (454/1 112), of which grade 2-3 AKI accounted for 11.9%. Multivariate analysis showed that age (OR=1.049, 95%CI 1.022-1.077, P<0.001), body mass index (OR=1.065, 95%CI 1.010-1.123, P=0.020) and time interval between preoperative coronary angiography and cardiac surgery within 24 hours (OR=1.625, 95%CI 1.116-2.364, P=0.011) were independent predictors of postoperative AKI. Patients who underwent coronary angiography within 24 hours before surgery had a 10.6% higher incidence of postoperative AKI compared to those who underwent angiography ≥24 hours before surgery (P=0.004). Patients who underwent valve surgery with or without coronary artery bypass grafting (CABG) had a higher risk of AKI than those who only underwent CABG. The in-hospital stay of patients who developed AKI was 2 days longer than those without AKI. However, undergoing coronary angiography within 24 hours before cardiac surgery did not prolong the length of ICU stay or hospital stay, nor did it increase the risk of death or renal failure after the operation. Conclusion Undergoing coronary angiography within 24 hours before cardiac surgery increases the risk of postoperative AKI.
