Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

Tumor-associated macrophage(TAM)play a crucial role in the immune microenvironment of lung can-cer.Through changes in their phenotype and phagocytic functions,TAM contribute to the initiation and progression of lung cancer.By promoting the formation of an immune-suppressive microenvironment and accelerating the growth of abnormal tumor vasculature,TAM facilitate the invasion and metastasis of lung cancer.Macrophages can polarize into different subtypes with distinct functions and characteristics in response to various stimuli,categorized as anti-tumor M1 and pro-tumor M2 types.In tumor tissues,TAM typically polarize into the alternatively activated M2 phenotype,exhibiting inhibitory effects on tumor immunity.This article reviews the role of anti-angiogenic drugs in modulating TAM phenotypes,highlighting their po-tential to reprogram M2-type TAM into an anti-tumor M1 phenotype.Additionally,the functional alterations of TAM play a significant role in anti-angiogenic therapy and immunotherapy strategies.In summary,the regulation of TAM polarization and function opens up new avenues for lung cancer treatment and may serve as a novel target for modulating the immune microen-vironment of tumors.

Objective:To analyze the Helicobacter pylori ( Hp) infection status in patients with colorectal polyp, and to study the relationship between the clinical features of colonoscopy and the Hp infection. Methods:The clinical data of 637 patients underwent colonoscopy from January to December 2022 in Dalian Central Hospital of Dalian University of Technology were retrospectively analyzed. The Hp infection status was detected by 14C-urea breath test. The relevant clinical data were recorded including age, gender, body mass index (BMI), total cholesterol (TC), triacylglycerol (TG), smoking history, Hp infection status, polyp diameter, polyp number, polyp location and polyp pathological classification. Multivariate Logistic regression was used to analyze the independent risk factors of colorectal polyp. Results:Among the 637 patients, 437 patients suffered from colorectal polyp (colorectal polyp group), and 200 patients had no colorectal polyp (control group). There were no statistical difference in age, TC and smoking history between two groups ( P>0.05); the male proportion, BMI, TG and Hp infection rate in colorectal polyp group were significantly higher than those in control group: 57.44% (251/437) vs. 35.00% (70/200), (24.34 ± 3.24) kg/m 2 vs. (23.70 ± 3.40) kg/m 2, 1.47 (0.93, 1.75) mmol/L vs. 1.31 (0.86, 1.63) mmol/L and 54.46% (238/437) vs. 40.00% (80/200), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that gender and Hp infection were independent risk factors of colorectal polyp ( OR = 2.260 and 1.545, 95% CI 1.568 to 3.258 and 1.082 to 2.208, P<0.01 or <0.05). Among the 437 patients in the colorectal polyp group, Hp infection was in 238 cases, and non- Hp infection was in 199 cases. There was no statistical difference in polyp location between Hp infection patients and non- Hp infection patients ( P>0.05); the rates of polyp diameter ≥0.5 cm, multiple polyp and adenomatous polyp in Hp infection patients were significantly higher than those in non- Hp infection patients: 66.81% (159/238) vs. 53.27% (106/199), 55.04% (131/238) vs. 36.68% (73/199) and 67.23% (160/238) vs. 54.77% (109/199), and there were statistical differences ( P<0.01). Conclusions:Hp infection is an important pathogenic factor for colorectal polyp. Hp infection is associated with some clinical features of colorectal polyp.

Objective:To carry out a scoping review on characteristics and effects of intervention program for promoting motor behavior among older adults in the community based on transtheoretical model (TTM), so as to explore the mechanism and connotation of TTM guiding strategy selection in the intervention program.Methods:The literature on the intervention program for promoting motor behavior among older adults in the community based on TTM was systematically searched in PubMed, Embase, CINAHL, Cochrane Library, PsycINFO, China National Knowledge Infrastructure and Wanfang Data. The search period was from database establishment to October 11, 2023. Two researchers conducted a summary and data analysis of the included literature.Results:A total of 15 articles were included, and the intervention framework included two types according to behavior change stages and behavior change patterns. The intervention strategy mainly included 17 items, such as emphasizing the benefits of exercise and drawbacks of no-exercise, establishing family support relationships, sharing exemplary experiences, rewarding, setting reminders, and signing commitments. The intervention strategies mainly involved 14 forms such as health lectures, one-on-one communication, exercise commitment letters, exercise logs, group communication meetings, and material/honor. The outcome measures consisted of feasibility (safety, retention, attendance, satisfaction) and effectiveness (exercise compliance, behavioral stage changes, physical function, self-efficacy, decision balance and so on) .Conclusions:The stages of change in TTM can guide the design of intervention frameworks for promoting motor behavior among older adults in the community, and the change program can guide the intervention strategies and design of application forms. The characteristic of the TTM based intervention program for promoting motor behavior among older adults in the community is that it contains intervention strategies that are suitable for each stage of behavior, and has short-term effectiveness and feasibility in terms of results. It is necessary to further clarify the details of the intervention program to explore its long-term effectiveness, and conduct follow-up.

Objective:To investigate the establishment method, coordination points and safe transport management strategy of vena-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with downtime difficulties during cardiopulmonary bypass (CPB).Methods:A observation study was conducted. The patients admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to October 2022 were enrolled. These patients could not be separated from CPB and received VA-ECMO-assisted CPB surgery. The clinical data of the patients were recorded, including the basic information of the patients, the data of VA-ECMO establishment and transport process, the clinical indicators before and after VA-ECMO installation, the operation data of VA-ECMO and clinical outcomes. The experience was summarized from the aspects of extracorporeal membrane oxygenation (ECMO) establishment, transport process, team cooperation, and adverse events during transport. The clinical indicators before and after ECMO operation were compared. According to whether ECMO was successfully weaned, the patients were divided into a successful weaning group and a failure weaning group, and the clinical data between the two groups were compared.Results:Eighteen patients who underwent VA-ECMO-assisted CPB were enrolled, including 10 males and 8 females. The average age was (56.7±12.3) years old. Preoperative left ventricular ejection fraction (LVEF) was 0.46±0.10, and the main reasons for switching to VA-ECMO assistance included right ventricular systolic weakness in 6 cases, total cardiac systolic weakness in 5 cases, left ventricular systolic weakness in 4 cases, high pulmonary arterial pressure in 2 cases, and intractable ventricular fibrillation in 1 case. Among the 18 patients transferred from CPB to VA-ECMO, 10 cases were successfully weaned and 8 cases failed. In ICU, 8 cases survived, 5 cases died, and 5 cases gave up treatment and discharged. The average time for successful CPB to VA-ECMO establishment was (24.6±7.4) minutes, initial blood flow was (3.3±0.4) L/min, and transit time was (8.4±1.5) minutes. ECMO-assisted duration averaged (82.0±69.3) hours. Adverse events occurred in 9 patients during ECMO establishment and transfer. Post-ECMO onboarding for 4 hours, significant improvements were noted in blood lactic acid (Lac), pH value, mean arterial pressure (MAP), central venous oxygen saturation (ScvO 2) as compared with pre-ECMO onboarding [Lac (mmol/L): 10.5±7.0 vs. 15.2±6.8, pH value: 7.38±0.92 vs. 7.26±0.87, MAP (mmHg, 1 mmHg≈0.133 kPa): 74.9±13.7 vs. 58.4±17.0, ScvO 2: 0.678±0.065 vs. 0.611±0.061, all P < 0.01], and vasoactive-inotropic score (VIS) was also decreased (39.8±29.8 vs. 68.9±64.4, P < 0.01). Compared with successful weaning group, the patients in the failed weaning group exhibited higher pre-machine Lac (mmol/L: 18.8±7.8 vs. 12.3±4.3, P < 0.05), longer CPB time [minutes: 238.0 (208.8, 351.2) vs. 200.0 (185.8, 217.0), P < 0.05], and shorter ECMO-assisted time [hours: 19.5 (11.0, 58.8) vs. 94.5 (65.8, 179.8), P < 0.01]. However, there was no statistically significant difference in pre-machine pH value, ScvO 2, MAP, VIS score, and initial blood flow and establishment time of ECMO between the two groups. Conclusions:VA-ECMO is an effective circulatory aid for CPB surgery that cannot be weaned after CPB. The establishment and transfer of CPB "bridge" to ECMO aid depends on multi-disciplinary treatment (MDT) cooperation. The success rate of ECMO weaning is related to the Lac and CPB duration. If it is not possible to detach from the CPB successfully, VA-ECMO should be initiated as early as possible.

Objective:To explore the relationship between olfactory dysfunction and mild cognitive impairment (MCI) among elderly people in the community so as to provide a reference for screening and risk factor management of the MCI population.Methods:From March to June 2023, elderly individuals from Donghuashi and Fangzhuang communities in Beijing were selected as the study subjects by convenience sampling. Study subjects were surveyed using the General Information Questionnaire, Mini-Mental State Examination, Montreal Cognitive Assessment, Barthel Index, Sniffin' Sticks Test, 7-item Generalized Anxiety Disorder Scale, and 15-item Geriatric Depression Scale. Binary logistic regression was used to analyze the factors that influence MCI among elderly people in the community.Results:A total of 252 questionnaires were distributed and 243 valid questionnaires were collected, with an effective response rate of 96.4% (243/252). Among 243 elderly people in the community, 75 experienced MCI, with an incidence of 30.9% (75/243). Binary Logistic regression analysis showed that the probability of MCI in elderly people with olfactory dysfunctions was 1.979 times that in elderly people without olfactory dysfunctions and age, previous occupational type and frequency of mental activity were the influencing factors for the occurrence of MCI ( P<0.05) . Conclusions:The incidence of MCI is high among elderly people in the community, especially those with olfactory dysfunctions. Nursing staff should pay attention to the role of olfactory dysfunction in cognitive function screening and risk factor management.

Objective:To evaluate the potential of 177Lu-prostate specific membrane antigen (PSMA)-3Q in the treatment of metastatic castration-resistant prostate cancer (mCRPC) and compare it with 177Lu-PSMA-I&T. Methods:177Lu-PSMA-3Q was prepared and the quality control and stability testing were performed. Pharmacokinetic evaluation and biodistribution of 177Lu-PSMA-3Q and 177Lu-PSMA-I&T were conducted in normal BALB/c mice and 22Rv1 tumor-bearing mice. SPECT imaging was performed on 2 patients (60 and 76 years old) with mCRPC from Chinese PLA General Hospital at 24, 72, and 120 h after injection of 177Lu-PSMA-3Q or 177Lu-PSMA-I&T ((7.40±0.74) GBq). Data were analyzed by using independent-sample t test. Results:177Lu-PSMA-3Q was prepared with the total activity of 74 GBq, the yield rate of 95% (uncorrected), and the radiochemical purity was still above 95% after 168 h at room temperature. The distribution half-lives of 177Lu-PSMA-3Q and 177Lu-PSMA-I&T were (0.75±0.22) and (0.86±0.19) min, and the clearance half-lives were (24.74±3.77) and (29.53±3.42) min. Biodistribution of normal mice showed that the uptake values in the liver, lungs, and kidneys 5 d after injection of 177Lu-PSMA-3Q were lower than those of 177Lu-PSMA-I&T ( t values: 4.24-8.36, all P<0.05). The tumor uptake of 177Lu-PSMA-3Q after 24 h injection was the highest and was higher than that of 177Lu-PSMA-I&T ((0.856±0.183) vs (0.579±0.126) percentage activity of injection dose per gram of tissue (%ID/g); t=2.78, P=0.024) in 22Rv1 tumor-bearing mice. The rapid clearance pattern resulted in a higher tumor/muscle (T/M) ratio for 177Lu-PSMA-3Q (99.604±11.106), which was significantly higher than that for 177Lu-PSMA-I&T (45.078±10.444; t=7.80, P<0.001). According to SPECT imaging of patients with mCRPC, the residual lesion counts of 177Lu-PSMA-3Q and 177Lu-PSMA-I&T at 120 h accounted for 0.32±0.05 and 0.58±0.04 of those at 24 h, with significant difference ( t=7.62, P=0.002). Conclusion:177Lu-PSMA-3Q is easy to label, and has high yield and radiochemical purity, good stability, excellent biological performance, good targeting ability in patients, longer retention time, and fast background clearance rate, which is an ideal prostate cancer treatment drug targeting PSMA.

Esophagogastric variceal bleeding (EGVB) is one of the main complications of decompensated portal hypertension, especially in patients with liver cirrhosis, and it often has a high mortality rate. Medication combined with endoscopy is the main prevention and treatment method for EGVB, while transjugular intrahepatic portosystemic shunt (TIPS) combined with variceal embolization can also be selected for some high-risk patients, and individualized diagnosis and treatment of portal hypertension based on hepatic venous pressure gradient should become the latest consensus and the main strategy. This article mainly reviews endoscopic therapy and TIPS for the prevention and treatment of EGVB patients with decompensated portal hypertension in terms of selection of indications, incidence rate of complications, and respective advantages and disadvantages.
