Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

Objective To understand the status of body image disturbance and its influencing factors in patients with ankylosing spondylitis (AS), so as to provide a scientific basis for the clinical management of AS. Methods A total of 353 AS patients admitted from January 2022 to December 2024 were selected as research subjects. Chinese version of Body Image Disturbance Questionnaire (BIDQ) was used to investigate the body image disturbance in AS patients. Single factor analysis was performed by t test and analysis of variance, and multiple factors were analyzed by multivariate linear regression. Results The total score of BIDQ in 342 AS patients was (25.01±4.22). Multivariate linear regression analysis results showed that self-paid medical expense, nighttime VAS score and negative emotion PANAS score could positively predict body image disturbance in AS patients (standardized regression coefficient=0.413, 0.413, 0.460, P<0.05), and PSSS score, positive emotion PANAS score and exercise management CDSSM score could negatively predict body image disturbance (standardized regression coefficient=-0.245, -0.134, -0.247, P<0.05). Conclusion The body image disturbance in AS patients is worthy of clinical attention. Nighttime pain, negative emotion and self-paid medical treatment can increase the risk of body image disturbance. Positive emotion, social support and high self-management level of exercise behavior can reduce the formation of body image disturbance, which can provide new ideas for clinical management of AS patients.

Objective To analyze the distribution status of the end digits of standardized blood pressure measurement recordings in the clinic and the effectiveness of standardized blood pressure measurement for community hypertension screening. Methods The first visit blood pressure measurement data from the Community Health Service Center in Jing'an District, Shanghai from June 2023 to May 2024 were collected and analyzed. According to different measurement methods, the data were divided into two groups: standardized blood pressure measurement and conventional blood pressure measurement. SPSS 19.0 software was used for data analysis. The differences in the distribution balance of the end digits of blood pressure values and the detection rate of blood pressure elevation between the two different groups were analyzed. Results The frequency range of the end digits of blood pressure recorded values in the standardized pressure measurement group was 9.42% to 10.83%, and the detection rate of elevated blood pressure was 24.89%. The conventional pressure measurement group had a preference of the end digit ^"0^", and the detection rate of elevated blood pressure was only 2.12%. The results of multiple logistic regression analysis showed that gender, age, season, and different blood pressure measurement modes were all influencing factors for the detection rate of elevated blood pressure. Conclusion The standardized blood pressure measurement mode in the clinic is suitable for community hypertension screening and pressure measurement, with higher data quality than the conventional pressure measurement mode.

Acute respiratory distress syndrome (ARDS) is a severe clinical condition characterized by acute respiratory failure due to widespread pulmonary inflammation and edema. The incidence of ARDS among intensive care unit (ICU) patients is approximately 10%, with mortality rates ranging from 35% to 45% and exceeding 50% in severe cases.[1] Identifying and controlling risk factors for ARDS is critical for early prevention. Smoking remains a significant global public health issue, affecting one-third of adults and 40% of children through exposure to secondhand smoke.[2] In an animal study, cigarette smoke impaired lung endothelial barrier function through oxidative stress and exacerbated lipopolysaccharide-induced increases in vascular permeability in vivo. This finding is consistent with the pathological changes observed in ARDS.[3] Although many observational studies have suggested a potential link between smoking and ARDS, the causal relationship remains unclear. This study uses Mendelian randomization (MR) to explore whether smoking behavior causally influences ARDS and investigates the mechanisms by which smoking may contribute to ARDS development through transcriptomic analysis of the Gene Expression Omnibus (GEO) database.

Objective To analyze etiology and DNA genotypes of human adenovirus (HAdV) in 5566 children with acute lower respiratory infection (ALRI). Methods A total of 5 566 children with ALRI admitted to the hospital were between October 2023 and October 2024, and their nasopharyngeal aspirates were collected. HAdV and the other etiology were detected by real-time fluorescent quantitative polymerase chain reaction (qPCR). The viruses isolation in HAdV positive samples was performed, and DNA genotypes of the isolated viruses were detected by PCR amplification. The clinical characteristics of children with ALRI-HAdV and different DNA genotypes were analyzed. Results Among the 5 566 children with ALRI, positive rate of HAdV was 27.56% (1534/5566). The positive rate was the highest in those with age of 3-6 years (57.51%). There was HAdV infection throughout the year, and the incidence was the highest in summer (41.39%). Among 1534 children with HAdV positive, there were 976 cases with pneumonia and 558 cases with bronchitis. The common clinical manifestations were fever, cough, dry and sore throat, and common complications were respiratory failure and myocardial injury. There were 1201 children with successful classifications, proportions of HAV-B, HAV-C and HAV-E were 53.04%, 42.96% and 4.00%, respectively. The detection rate of HAV-B3 in subgroup B was the highest (34.05%), followed by HaV-C1 in subgroup C (19.48%). There was no difference in distribution of HAdV classifications among children with different genders and age (P>0.05). However, there were differences in distribution of HAdV classifications among admission children in different seasons (P<0.05). Among 1201 children, there were 457 cases with single HAdV infection and 744 cases with mixed infection, and incidence of mixed infection (Mycoplasma pneumoniae infection + influenza virus infection) was higher. Conclusions The incidence of HAdV infection is the highest in ALRI children with age of 3-6 years, and the onset is mainly in summer. The main infection type is Mycoplasma pneumoniae infection + influenza virus infection, main manifestations include fever, cough, dry throat and sore throat, and main genotypes of HAdV infection include HAdV-B3 and HAdV-C1.

Objective To investigate the relationship between Helicobacter pylori (Hp) infection and disease severity and pathological type of intestinal polyps in inpatients. Methods The data of 303 inpatients with intestinal polyps in the hospital from August 2022 to February 2025 were collected and analyzed. The clinical characteristics of patients were analyzed, and the influencing factors of pathological types of polyps were explored. Results Among the 303 inpatients with intestinal polyps, there were 135 Hp positive cases and 168 Hp negative cases. The number of polyps, maximum polyp diameter, number of ileocecus/ascending colon/transverse colon polyps, number of descending colon/sigmoid colon/rectal polyps and adenomatous polyps in the Hp-positive group were higher than those in the Hp-negative group (P<0.05). Multivariate logistic regression analysis indicated that age [OR (95%CI)=1.03 (1.01-1.05)] and positive Hp[OR (95%CI)=2.61 (1.62-4.20)] were independent risk factors of occurrence of adenomatous polyps (P<0.05). ROC curve results revealed that the AUCs of age, positive HP and combination in the diagnosis of adenomatous polyps were 0.574, 0.608 and 0.646, and the 95%CI values were 0.509-0.638, 0.545-0.672 and 0.584-0.708 respectively. The efficiency of combination of the two indexes was higher than that of single diagnosis. Conclusion Hp infection is associated with disease severity in inpatients with intestinal polyps, and it may be involved in the occurrence and development of adenomatous polyps.

Objective To investigate the current status and serologic characteristics of occult HBV infection in the adult physical examination population in Zigong region. Methods A total of 126 381 patients who were examined in the physical examination center and gastroenterology department of The First People's Hospital of Zigong City from April 2023 to September 2024 were screened, and 21 615 eligible cases were included in the study. The current status of infection was analyzed and serological patterns and serological characteristics of the included individuals were compared. Results This study screened 126 381 patients, all of whom underwent serum HBsAg testing, and 21 615 patients (17.10%) underwent HBV DNA testing, of which 7 992 were HBV DNA positive (>102 IU/mL) and HBsAg negative, accounting for 36.97% of the total number of patients who underwent HBV DNA testing. Anti-HBc positivity was significantly higher than other serologic patterns, and the lowest rate of HBV DNA positivity was found in those who were positive for anti-HBc, anti-HBs and anti-HBe. The lowest male-to-female ratio (1.25:1) was found in patients with both anti-HBc, anti-HBs and anti-HBe positivity, which was significantly lower than that of patients with the other three serologic characteristics (P=0.005). There were no significant differences in age, BMI, AST, ALT, and TBiL levels among patients with different serum characteristics (all P>0.05). The HBV viral load is highest in patients with anti HBc combined with anti HBe positivity, while the HBV viral load is lowest in patients with anti HBc positivity, anti HBs positivity, and all anti HBe positivity (P<0.001). Viral genotypes were predominantly B-type, and there were differences in genotype distribution among the four groups of patients (P<0.001). Conclusion The level of occult HBV infection was high in the adult medical examination population in Zigong region, mostly characterized by anti-HBc positivity, with the lowest male-to-female ratio among patients who were positive for anti-HBc, anti-HBs, and anti-HBe, and the highest HBV viral load among patients who were positive for anti-HBc combined with anti-HBe.

Objective To analyze the clinical characteristics and high risk factors of prognosis in patients with chronic heart failure and renal insufficiency. Methods A total of 499 patients with chronic heart failure and renal insufficiency from September 2022 to September 2024 were selected. The clinical data of patients were collected, and the clinical characteristics were analyzed. After 3 months of follow-up, the patients were divided into survival group and death group according to the prognosis status. Univariate analysis, and multivariate logistic regression analysis were adopted to analyze the risk factors affecting the prognosis of patients. Results According to different ejection fraction values, patients were classified into HFrEF group (n=164), HFmrEF group (n=103) and HFpEF group (n=232). The age in HFpEF group was the lowest (P<0.05). The cardiac function grading was the highest in HFrEF group, and the systolic blood pressure was lower while the diastolic blood pressure was higher than that in the other two groups (P<0.05), and there were no differences in cardiac function, systolic blood pressure and diastolic blood pressure between HFmrEF group and HFpEF group (P>0.05). The levels of Hb and ALB in HFpEF group were higher than those in HFrEF group (P<0.05), and no differences were observed between HFmrEF group and the other two groups (P>0.05). HFrEF group had the lowest total cholesterol and Scr, and the highest serum uric acid, eGFR, BNP and cTnI (P<0.05). The level of hs-CRP in HFmrEF group was the lowest. The LVEDD was lower in HFpEF group than that in the other two groups (P<0.05). The levels of serum uric acid, Scr and hs-CRP in death group were higher while the eGFR was lower compared to survival group (P<0.05). After logistic analysis, it was found that elevated levels of serum uric acid and hs-CRP and decreased eGFR were risk factors for poor prognosis (P<0.05). Conclusion Patients with chronic heart failure and renal insufficiency are mainly HFpEF. Elevated serum uric acid and hs-CRP and decreased eGFR are the high risk factors for poor prognosis.
