Objective: To identify influencing factors associated with the prognosis of sepsis patients receiving blood component transfusion, and to provide a more rational and scientific transfusion strategy for clinical management. Methods: Clinical data of 232 patients with sepsis treated at the Second Xiangya Hospital of Central South University between January 2022 and December 2023 were retrospectively analyzed. These patients were categorized into the transfusion group (n=64) and the non-transfusion group (n=168) based on whether they received transfusions, and the patients in the transfusion group were further divided into non-survivor group (n=26) and survivor group (n=38) based on their survival outcome. Baseline characteristics and clinical characteristics were compared between two groups. Factors impacting the prognosis of sepsis patients undergoing blood component transfusion were identified using logistic regression. Results: Compared to the non-transfusion group, the transfusion group showed significantly higher levels of coagulation indicators (prothrombin time, activated partial thromboplastin time, international normalized ratio, D-dimer) and inflammatory markers (C-reactive protein, procalcitonin, interleukin-6), while the level of hemoglobin, platelet, lymphocyte, fibrinogen, albumin, blood glucose, and oxygen saturation were significantly lower (P<0.05). The [M(P , P )] for C-reactive protein (mg/L), hemoglobin (g/L), and platelet count (×10 /L) in the transfusion vs non-transfusion groups were 178.0(156.1-178) vs 102.7(74.0-119.6), 88.5(72.3-113.0) vs 110.5(101-121.8), and 63.0(26.5-156.5) vs 202.5(108.3-286.8), respectively (all P<0.05). Logistic regression analysis revealed that hemoglobin level, platelet count, lactate concentration, and the storage duration of transfused red blood cells were independent risk factors affecting the survival outcomes of sepsis patients receiving transfusions (P<0.05). In septic transfusion patients, the [M(P , P )] lactate concentration (mmol/L) and RBC storage time (d) in the non-survivor vs survivor groups were 3.5(1.9-7.7) vs 2.1(1.3-3.5), 18.0 (13.0-18.0) vs 12.0(9.0-14.0), respectively (both P<0.05). Conclusion: Compared to non-transfused sepsis patients, those receiving transfusions exhibited poorer baseline conditions, more severe infections, and worse survival outcomes. More importantly, the study found that the timing of transfusion decisions and the quality control of blood products (such as storage duration) may directly impact patient prognosis, providing critical evidence for optimizing transfusion strategies in septicemia patients.

Objective:To analyze the current status and trends of lung cancer incidence and mortality in China and selected global regions, providing evidence for lung cancer prevention strategies in China.Methods:We extracted data from the GLOBOCAN 2022 database. Age-standardized Incidence rate (ASIR) and Age-standardized Mortality rate (ASMR) were calculated using Segi's world standard population. Epidemiological patterns were analyzed by region, age, sex, and human development index (HDI). Simple linear regression and Spearman's rank correlation coefficient were used to examine associations between HDI and ASIR/ASMR.Results:In 2022, global lung cancer incidence and mortality reached 2.48 million and 1.82 million cases respectively, with age-standardized rates of 23.6 per 100 000 (ASIR) and 16.8 per 100 000 (ASMR). Gender disparities were prominent, with male ASIR and ASMR being 2.0-fold and 2.5-fold higher than females. Elderly populations showed 11.6-fold higher ASIR and 14.4-fold higher ASMR compared to working-age adults. HDI demonstrated strong positive correlations with both ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.74, P＜0.001). China accounted for 1.06 million new cases and 0.73 million deaths, with ASIR (40.8 per 100 000) and ASMR (26.7 per 100 000) exceeding global averages by 1.7-fold and 1.6-fold respectively. Chinese males showed 1.7-fold higher ASIR and 2.7-fold higher ASMR than females. Trend analysis revealed persistently high male incidence in China whereas rapidly increasing female rates, narrowing gender disparities. Projections estimate 1.80 million incident cases and 1.41 million deaths by 2050, representing 69.3% and 92.0% increases from 2022 levels. Conclusions:Significant heterogeneity exists in lung cancer burden across demographics and development levels, with strong HDI correlations. China bears disproportionate disease burden, necessitating intensified prevention efforts. These findings underscore the urgency of targeted interventions in high-risk populations.

Objective:To comprehensively evaluate the cost and cost-effectiveness of the colorectal cancer screening program for key populations in Zhejiang Province from 2020 to 2022, and provide reference for optimizing colorectal cancer screening strategies.Methods:Based on the colorectal cancer screening program for key populations in Zhejiang Province from 2020 to 2022, parameters such as initial screening positivity rates, colonoscopy compliance rates, and detection rates for colorectal-related lesions among residents aged 50-74 were obtained. Questionnaire surveys assessed program costs and direct medical costs associated with colorectal cancer-related lesions. From a health system perspective, the cost-effectiveness ratio was calculated using the Early Detection Cost Index (EDCI) and the cost per detected case, followed by sensitivity analysis.Results:A total of 5 881 364 screenings were completed from 2020 to 2022. The initial screening positive rate (positive for either questionnaire or fecal immunochemical testing ) was 16.83%, with a colonoscopy compliance rates of 33.96% ( n=336 150). Detection rates for non-advanced adenomas, advanced adenomas, and colorectal cancer were 24.83% ( n=83 453), 11.91% ( n=40 033), and 1.01% ( n=3 397), respectively. Initial screening positivity rates and detection rates increased with age, while colonoscopy compliance rates decreased with age. Cost analysis showed a total project investment of 378 730 457 yuan, with initial screening costing 146 633 103 yuan (38.72%) and diagnostic colonoscopy 232 097 354 yuan (61.28%). The average cost per initial screening and diagnostic colonoscopy was 24.93 and 690.46 yuan, respectively. Direct medical costs for non-advanced adenomas, advanced adenomas, and colorectal cancer at stages Ⅰ, Ⅱ, Ⅲ, and Ⅳ were 4 921, 8 380, 42 547, 62 156, 66 720, and 72 334 yuan, respectively. Cost-effectiveness analysis indicated that screening needed to detect one case of colorectal cancer required 1 731 people and cost 111 490 yuan; the cost per detected advanced adenoma was 9 460 yuan, and the EDCI was 0.09. Costs decreased with increasing age per detected colorectal lesion. Sensitivity analysis showed that increasing colonoscopy compliance could reduce the cost-effectiveness ratio. Conclusions:The colorectal cancer screening program for key populations in Zhejiang Province demonstrates cost-effectiveness. Improving colonoscopy compliance can enhance overall screening effectiveness and economic benefits.

Objective To observe the correlations of chest CT quantitative parameters and one-year readmission in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Totally 225 AECOPD patients were included and divided into the readmission group(group A,n=61)and non-readmission group(group B,n=164)according to whether readmitted due to acute exacerbation within one year or not.Quantitative CT parameters,including the percentage of low attenuation area volume to total lung volume(LAA％)and intrapulmonary vascular volume(IPVV)of the whole lung,left/right lung and each lobe,as well as the bronchial lumen area(LA)and percentage of bronchial wall area(WA％)of grades 3-8 were compared between groups.Spearman correlations were used to analyze the correlations between quantitative CT parameters and one-year readmission.Results LAA％of the whole lung,right lung,upper lobe of both lungs,middle lobe of the right lung,and lower lobe of the right lung in group A were higher than that in group B(all P＜0.05),which were weakly positively correlated with readmissions within one year(r=0.142-0.187,all P＜0.05).Significant differences of the upper lobe of right lung LAgrade 6,lower lobe of left lung LAgrade 6,lower lobe of left lung LAgrade 8,upper lobe of right lung WA％grade 5,upper lobe of right lung WA％grade 8 and lower lobe of left lung WA％grade 8 were found between groups,which were all correlated with readmissions within one year except for the lower lobe of the left lung LAgrade 6(all P＜0.05).Conclusion One-year readmission in AECOPD patients might be associated with severe airway remodeling and emphysema.

Objective:To investigate the dosimetric characteristics of intensity modulated proton therapy (IMPT) and intensity modulated radiation therapy (IMRT) for lung cancers.Methods:Three lung cancer patients (central-lower, central, and peripheral types) admitted to Shandong Cancer Hospital and Institute from January 2024 to May 2024 were selected as the research subjects. IMPT and IMRT plans were designed for each case based on the anatomical location of the clinical target volume and the dose constraints for organs at risk (OARs). Dosimetric parameters, including conformity index (CI), homogeneity index (HI), and gradient index (GI) for target coverage, as well as OARs dosimetric parameters were evaluated. The volume of additional dose deposition in the body was compared by assessing regions receiving 10%, 30%, and 50% of the prescription dose.Results:For all three cases, IMRT plans demonstrated higher CI values (0.80, 0.60, and 0.79) compared to IMPT plans (0.61, 0.57, and 0.34). IMPT plans yielded lower HI values (0.07, 0.06, and 0.06) than IMRT plans (0.09, 0.15, and 0.09) and lower GI values (2.84, 2.47, and 4.56 vs. 4.91, 3.09, and 4.99 for IMRT plans). Compared with the IMRT plans, the low-dose region in the ipsilateral lung was significantly reduced in IMPT plans (V 5 of the IMPT plans were 20.59%, 46.29%, 10.94%, respectively; V 5 of the IMRT plans were 48.91%, 60.63%, 19.92%, respectively), but there was no significant advantage in the high-dose region compared to IMRT plans (V 20 of the IMPT plans were 12.88%, 34.75%, 5.21%, respectively; V 20 of the IMRT plans were 21.70%, 36.50%, 5.31%, respectively). The dose to the contralateral lung and heart was significantly reduced in IMPT plans [the D mean of the contralateral lung in the IMPT plans were 0.08, 0.04, and 0.00 Gy (RBE), respectively, and those in the IMRT plans were 3.25, 1.18, and 0.55 Gy, respectively; the heart D mean in the IMPT plans were 6.23, 7.04, and 0.00 Gy (RBE), respectively, while those of the IMRT plans were 18.33, 10.27, and 0.08 Gy, respectively). IMPT plans significantly reduced the volumes receiving 10% of the prescription dose by 65.94%, 25.57% and 72.47%, respectively, compared to IMRT plans. The volumes IMPT plans occupied by 30% of the prescription dose area in the body were reduced by 54.97%, 26.47% and 39.04%, respectively, compared to the IMRT plans. The volumes IMPT plans occupied by 50% of the prescription dose area in the body were reduced by 54.49%, 30.43% and 28.89%, respectively, compared to the IMRT plans. Conclusions:IMPT plan significantly reduces the V 5 of the ipsilateral lung, the D mean of the contralateral lung and the heart, while maintaining target coverage compared with IMRT plan for lung cancers. However, IMPT plan does not show much more advantage than IMRT plan in the ipsilateral lung V 20. IMPT can reduce the additional exposure volume within the body.

Objective:To construct a rat model of non-alcoholic fatty liver disease(NAFLD)by choline-deficient high fat diet(CDHFD),and to observe the association between feeding cycle and antioxidant pathway.Methods:The study lasted 16 weeks and was divided into 4 cycles.Detection of pathological changes and expression of antioxidant enzymes in rats liver in different cycles.Results:The early stage of liver steatosis and inflammation in model rats was 2～4 weeks,non-alcoholic steatohepatitis(NASH)stage was 4～8 weeks,and liver fibrosis progression was 8～16 weeks.Mechanistic studies had shown that the expressions of antioxidant enzymes Nrf2,SOD and GSH-Px in the liver of NAFLD rats gradually decreased with the extension of the feeding cycle.Conclusion:Different modeling cycles can successfully induce the pathological changes of steatosis,inflammation and liver fibrosis in rat liver,and the pathological changes are time-dependent with the expressions of antioxidant enzymes.

Objective:To explore the effects of multi-dimensional nursing based on empowerment theory in patients undergoing thoracoscopic and laparoscopic esophagectomy.Methods:A convenience sampling method was used to select 110 esophageal cancer patients who were admitted to Henan Provincial People's Hospital from August 2022 to April 2024. Patients were randomly divided into two groups using a random number table: the control group and the observation group, with 55 patients in each group. The control group received routine care, while the observation group received multi-dimensional nursing based on empowerment theory in addition to routine care. The two groups were compared in terms of stress responses (heart rate, systolic blood pressure, diastolic blood pressure) , self-care ability, nutritional status (hemoglobin, albumin) , and nursing satisfaction.Results:After the intervention, the observation group had lower heart rate, systolic blood pressure, and diastolic blood pressure compared to the control group, with statistically significant differences ( P<0.01) . The self-care ability score in the control group was lower than that in the observation group, with a statistically significant difference ( P<0.01) . The observation group also had higher hemoglobin and albumin levels compared to the control group, with statistically significant differences ( P<0.01) . The nursing satisfaction rate in the observation group was higher than that in the control group, with a statistically significant difference ( P<0.05) . Conclusions:Multi-dimensional nursing based on empowerment theory can effectively reduce stress responses, improve self-care ability, enhance nutritional status, and increase nursing satisfaction in esophageal cancer patients.
