Objective To analyze the epidemiological distribution characteristics and influencing factors of treat-ment outcome of pulmonary tuberculosis(PTB)patients complicated with diabetes mellitus(DM)in Bijie City from 2017 to 2022,and provide reference for formulating prevention and control measures of PTB-DM.Methods The registered management cases of PTB patients combined with DM from the tuberculosis surveillance report informa-tion management system in Bijie City in 2017-2022 were collected.Changing trends in annual registration rates and successful treatment rates were analyzed with Joint-point regression models.Different characteristics between pa-tients with PTB-DM and PTB alone were conducted comparative analysis;the influencing factors of treatment out-come were analyzed by x2 test and binary logistic regression analysis.Results A total of 679 PTB-DM patients were registered in Bijie City from 2017 to 2022,accounting for 1.53％of total PTB patients,the annual registration rate increased from 1.11/100 000 in 2017 to 3.08/100 000 in 2022,with an increasing trend in the annual percentage change(APC=26.67％,95％CI:5.36％-52.29％,t=3.564,P=0.024).In the analysis on characteristics,the proportion of PTB-DM male patients,age ≥45 years and farmers,the ratio of direct consultation to transfer treat-ment,the pathogenicity positive rate,the proportion re-treatment,and rate of delay in consultation were all higher than those of PTB alone;successful treatment rate and proportion of floating population were all lower than PTB alone,difference were all statistically significant(all P＜0.05).The successful treatment rate of PTB-DM patients in Bijie City from 2017 to 2022 was 87.80％.Age,occupation,pathogenicity diagnosis results were influencing fac-tors for treatment outcome in patients with PTB-DM,with farmers(OR=3.68,95％CI:1.22-11.09),with pathogenicity positivity(OR=2.84,95％CI:1.24-6.50),and without pathogenic detection result+tuberculous pleurisy(OR=11.35,95％CI:2.16-59.74)being risk factors for successful treatment.Conclusion Although the proportion of PTB-DM in the total PTB patients in Bijie City from 2017 to 2022 was not high,it showed an up-ward trend;it is necessary to attach great importance to male,re-treated,farmer,and pathogenicity positivity co-morbid patients in Bijie City,and strengthen the two-way screening of PTB-DM in high-risk populations.

Objective To investigate the expression of ACTN1 in cutaneous squamous cell carcinoma (CSCC) and its association with clinicopathological features and prognosis. Methods A total of 150 patients with cutaneous squamous cell carcinoma (CSCC) and 100 healthy controls were enrolled in this study. The serum expres-sion levels of ACTN1 were measured using ELISA. All CSCC patients underwent post-surgical follow-up and were categorized into a poor prognosis group (n=69) and a good prognosis group (n=81). Additionally,the 69 patients in the poor prognosis group were further classified into an ACTN1 lower expression subgroup (n=35) and an ACTN1 higher expression subgroup (n=34) based on the median expression level of ACTN1. Logistic regression analysis was employed to identify risk factors associated with poor prognosis in CSCC patients. ROC curve analysis was conducted to evaluate the clinical utility of serum ACTN1 expression levels in predicting poor prognosis in CSCC patients. Kaplan-Meier (K-M) survival analysis was utilized to assess the relationship between serum ACTN1 expres-sion levels and the median time to poor prognosis in the 69 patients with poor prognosis. Furthermore,40 additional CSCC patients were recruited to compare the expression levels of ACTN1 in CSCC tissues and adjacent tissues using immunohistochemistry. Results The serum expression levels of ACTN1 in the Control group and the CSCC group were (12.12±2.26) ng/mL and (4.56±1.02) ng/mL,respectively. Compared to the Control group,the serum expres-sion level of ACTN1 in the CSCC group was significantly decreased,and the difference was statistically significant (t=31.37,P<0.001). In the poor prognosis group,the proportion of tumors with a diameter ≥ 5 cm,low degree of tumor cell differentiation,subadipocyte invasion depth,lymph node metastasis incidence,and serum ACTN1 expression levels were all significantly higher compared to the good prognosis group,with statistical significance (P<0.05). Logistic regression analysis revealed that lymph node metastasis (OR=3.253) and elevated ACTN1 expression (OR=2.894) were independent risk factors for poor prognosis following CSCC surgery. The area under the curve (AUC) for serum ACTN1 expression in predicting poor prognosis post-surgery in CSCC patients was 0.911. At a cut-off value of 13.19 ng/mL for ACTN1,the diagnostic sensitivity and specificity were 89.78％ and 92.12％,respectively. The median time to poor prognosis was 25 months in the ACTN1 low-expression group and 18.5 months in the ACTN1 high-expression group,respectively. The median time to poor prognosis was significantly shorter in the ACTN1 high-expression group compared to the low-expression group (HR=6.627,P<0.001). Among 40 CSCC tissue samples,32 cases exhibited higher ACTN1 expression,while 8 cases showed lower expression. In contrast,among 40 paracancerous tissue samples,11 cases had higher ACTN1 expression and 29 cases had lower expression. The higher expression rate of ACTN1 in CSCC tissues was significantly elevated compared to paracancerous tissues (x2=22.175,P<0.001). Conclusion The serum expression level of ACTN1 in CSCC patients was significantly elevated,suggesting its potential as a biomarker for assessing post-surgical prognosis in CSCC patients.

Single-incision laparoscopic cholecystectomy (SILC) represents a significant evolution in minimally invasive surgery, designed to accomplish cholecystectomy via a single umbilical incision. This approach seeks to reduce abdominal wall trauma while optimizing cosmetic outcomes. SILC is a safe and feasible minimally invasive technique for cholecystectomy under defined conditions; however, its broader adoption will require further evidence-based research and the establishment of standardized protocols to support its widespread implementation. When performed by skilled surgeons in carefully selected patients, SILC demonstrates clinical outcomes comparable to those of conventional multiport laparoscopic cholecystectomy, with notable improvements in incision aesthetics. Nonetheless, the technique is limited by a constrained operative field and a protracted learning curve. In response, continuous advancements in instrumentation and procedural modifications have propelled the further development and clinical integration of SILC. Drawing on current literature and clinical experience, this review delineates the technical characteristics, current clinical applications, primary benefits, and prevailing challenges associated with SILC.

A retrospective analysis of the clinical data of seven acute B-lymphoblastic leukemia (B-ALL) patients with TCF3-HLF fusion gene-positive admitted to the First Affiliated Hospital of Soochow University from June 2017 to August 2022 was conducted to summarize their clinical features and prognoses. The seven B-ALL patients comprised four males and three females, with a median age of 18 (11-33) years. Five patients tested positive for CD33 expression, and four patients had a normal karyotype. Two patients had hypercalcemia at the initial diagnosis, and one patient developed hypercalcemia at relapse. Six patients presented with coagulation dysfunction at diagnosis. After induction chemotherapy, five out of seven patients achieved complete remission, of which four subsequently relapsed. Two patients did not achieve remission even after two rounds of induction chemotherapy, with one achieving complete remission after treatment with blinatumomab immunotherapy. Three patients underwent chimeric antigen receptor T cell therapy, whereas three patients subsequently underwent hematopoietic stem cell transplantation. Five patients died, while two patients survived with sustained complete remission. TCF3-HLF-positive B-ALL is rare and has a high relapse rate and poor prognosis.

Pulmonary fibrosis(PF)is a chronic progressive end-stage lung disease.However,the mechanisms un-derlying the progression of this disease remain elusive.Presently,clinically employed drugs are scarce for the treatment of PF.Hence,there is an urgent need for developing novel drugs to address such diseases.Our study found for the first time that a natural source of Prismatomeris connata Y.Z.Ruan(Huang Gen,HG)ethyl acetate extract(HG-2)had a significant anti-PF effect by inhibiting the expression of the transforming growth factor beta 1/suppressor of mothers against decapentaplegic(TGF-β1/Smad)pathway.Network pharmacological analysis suggested that HG-2 had effects on tyrosine kinase phosphorylation,cellular response to reactive oxygen species,and extracellular matrix(ECM)disassembly.Moreover,mass spec-trometry imaging(MSI)was used to visualize the heterogeneous distribution of endogenous metabolites in lung tissue and reveal the anti-PF metabolic mechanism of HG-2,which was related to arginine biosyn-thesis and alanine,asparate and glutamate metabolism,the downregulation of arachidonic acid meta-bolism,and the upregulation of glycerophospholipid metabolism.In conclusion,we elaborated on the relationship between metabolite distribution and the progression of PF,constructed the regulatory metabolic network of HG-2,and discovered the multi-target therapeutic effect of HG-2,which might be conducive to the development of new drugs for PF.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, with rapid progression and a poor prognosis. More and more studies have shown that there are small open reading frames (sORFs) on the molecular sequences of a large number of non-coding RNAs (ncRNAs), which can encode conserved peptides that play an important role in controlling the occurrence and development of HCC. This article introduces the discovery, prediction, and validation methods of ncRNA-encoding polypeptides and reviews its research progress, with the aim of providing new targets and ideas for early-stage diagnosis, targeted therapy, and prognosis assessment of HCC.
