With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective To assess mid- and long-term outcomes of ascending aortic wrapping (AAW) in adult patients undergoing aortic valve replacement (AVR). Methods We retrospectively analyzed clinical data of adult patients who underwent AVR and AAW in Fuwai Hospital from January 2010 to August 2019. Ascending aorta diameter (AAD) was measured by echocardiography or CT scan preoperatively and postoperatively. Results A total of 33 patients were enrolled, including 23 males and 10 females aged 22-73 (51.06±12.61) years. There was no perioperative death. The mean preoperative, postoperative and follow-up AAD of the patients were (46.06±3.54) mm, (34.55±5.17) mm, and (37.12±5.64) mm, respectively. The differences in the AAD between pre-operation and post-operation, and between pre-operation and the last follow-up were both statistically significant (P<0.05). The median follow-up time was 38.20 (18.80-140.30) months. The median increase rate of diameter was 0.63 (−0.11, 1.36) mm per year after the surgery. The increase rate was >5 mm per year in 1 patient, and >3 mm in another one. Conclusion The mid- and long-term outcomes of AAW in adult patients undergoing AVR are satisfactory and encouraging.

AIM: To analyze the changes of retinal structure and function before and after panretinal photocoagulation(PRP)in patients with proliferative diabetic retinopathy(PDR).METHODS: Prospective study. Totally 98 cases(98 eyes)of PDR patients who underwent PRP in Eye Hospital of Wenzhou Medical University from January 2022 to May 2023 were included. Optical coherence tomography angiography(OCTA)was used to detect central retinal thickness(CRT), central macular thickness(CMT), subfoveal choroidal thickness(SFCT), foveal avascular zone(FAZ), deep vascular complex(DVC)blood flow density, superficial vascular complex(SVC)blood flow density before and at 1 wk, 1 and 3 mo after PRP. During the follow-up, 1 eye underwent vitrectomy, 2 eyes were lost to follow-up, and finally 95 eyes completed 1 a follow-up, with a loss rate of 3%. According to the visual prognosis at 1 a after treatment, the patients were divided into two groups: 73 eyes in good prognosis group and 22 eyes in poor prognosis group(including 9 eyes of visual disability and 13 eyes of visual regression). The changes in retinal structure and function before and after PRP treatment were compared between the two groups of patients, and the receiver operating characteristic(ROC)curve and decision curve were used to analyze the predictive value of retinal structure and function for PDR treatment.RESULTS: There were statistical significant differences in PDR staging, CRT, CMT, SFCT, DVC blood flow density, and SVC blood flow density between the two groups of patients before treatment(all P<0.05). At 1 wk, 1 and 3 mo after treatment, the FAZ area of both groups decreased compared to before treatment, while the blood flow density of DVC and SVC increased compared to before treatment(both P<0.05). However, there was no significant difference in the blood flow density of FAZ, DVC, and SVC between the two groups at 1 wk, 1 and 3 mo after treatment(all P>0.05). The CRT, CMT and SFCT of the two groups at 1 wk after treatment were higher than those before treatment(all P<0.05), but there were no significant differences between the two groups(all P>0.05). The CRT, CMT and SFCT at 1 and 3 mo after treatment were lower than those at 1 wk after treatment and before treatment in both groups. The CRT, CMT and SFCT in the poor prognosis group at 3 mo after treatment were higher than those at 1 mo after treatment, and were higher than those in the good prognosis group(all P<0.05). ROC analysis showed that, at 3 mo after laser treatment in PDR patients, the area under the curve of the CRT, CMT, and SFCT alone or in combination after treatment for 1 a was 0.788, 0.781, 0.783, and 0.902, respectively, and the combined prediction value was better(P<0.05). Decision curve analysis showed that the combined detection of CRT, CMT, and SFCT in PDR patients at 3 mo after treatment can improve the predictive value of visual prognosis.CONCLUSION: The optimal time for retinal structure and function recovery in PDR patients after PRP treatment is between 1 wk and 1 mo. OCTA measurement of CRT, CMT, and SFCT at 3 mo after treatment can predict the visual prognosis during the 1 a treatment period.

Objective: To investigate the status quo and associated factors of drinking water knowledge, attitude and behavior among primary school students in rural areas, so as to provide evidence for health behavioral intervention of drinking water in primary school. Methods: Twentythree primary schools in rural area from Hebei, Henan, Shandong and Shanxi provinces were selected by using purposive sampling method from March 1 to April 27 in 2023. Selfdesigned questionnaires regarding knowledge, attitude and behavior of drinking water were distributed to all students in grade 3-6, and 2 173 valid questionnaires were obtained. Multivariate Logistic regression was used to analyze the influencing factors of drinking water knowledge, attitude and behavior of primary school students. Results: The attainment rates of drinking water knowledge, attitude and behavior level were 20.02%, 26.65%, and 31.20%, respectively, among primary school students. The median of daily water intake was 1 000 mL, and the average daily water intake was (1 172.99±771.89)mL. In addition, 66.31% of students water intake reached the minimum standard of 800 mL recommended. The results of multiple Logistic regression indicated that drinking water accessibility in school, health education of drinking water, and individual selfcontrol ability were positively correlated with the knowledge (OR=1.31, 1.57, 1.58), attitude (OR=2.07, 1.65, 1.73), behavior (OR=1.40, 1.49, 1.91) of drinking water and daily water intake (OR=1.41, 1.38, 1.20) (P<0.05). Conclusions Primary school students in rural areas are generally lack of appropriate health awareness on drinking water including knowledge, attitude and behavior. Schools should take targeted measures to focus on the cultivation of students selfcontrol ability, so as to improve students knowledge and attitudes of drinking water, and furthermore help students shape their healthy behaviors of drinking water.

Objective:To explore the psychological experience of ICU nurses caring for young patients with suicide attempts in a general hospital, and to lay a foundation for the study of psychological adjustment and intervention for ICU nurses.Methods:Twelve ICU nurses who had experience of caring for suicide attempted- young patients from Sir Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University were selected by using descriptive qualitative research method and the maximum difference method of the purposive sampling during October to December in 2023, and semi-structured in-depth personal interviews were conducted. Traditional content analysis method was used to sort out and analyze the data and extract the themes.Results:A total of 12 nurses completed the interview, 5 males, 7 females, aged 23-38(29.33 ± 4.14) years, three themes and seven sub-themes were extracted: psychological characteristics of care (avoidance of active communication, fear of care, empathy); the support required for nursing care (support from colleagues; support from nursing managers); self-growth after caregiving (self-growth in terms of life and death, and self-growth in terms of children′s education).Conclusions:ICU nurses have a certain degree of psychological pressure when taking care of young patients with suicide attempts, which will produce empathy for patients and affect their self-values. At the same time, they need support from colleagues and nursing managers. Therefore, general hospitals should pay attention to the psychological state of ICU nurses, carry out the targeted communication training and mental health support for ICU nurses, and help them gain positive nursing career growth and values.

Objective:To evaluate the technical feasibility and perioperative safety of pyeloplasty assis-ted by the CarinaTM modular laparoscopic surgical robotic system in patients with ureteropelvic junction obstruction(UPJO).Methods:From November to December 2024,five consecutive patients diagnosed with UPJO underwent robot-assisted pyeloplasty using the CarinaTM modular laparoscopic surgical system at Peking University First Hospital.Data on patient demographics,intraoperative parameters(including docking time,console time,and estimated blood loss),perioperative outcomes,follow-up results,and surgeons' subjective evaluations of system performance were prospectively collected.Descriptive statistics were used;continuous variables were presented as median(range),and categorical variables as frequen-cy and percentage.Results:The cohort included four females and one male.All the patients successfully completed the robotic procedure without conversion to open or conventional laparoscopic surgery.The me-dian age was 32 years(24-37 years),and the median body mass index was 21.6 kg/m2(15.8-27.3 kg/m2).The median docking time was 8 min(3-12 min),and the median console time was 91 min(71-125 min).Intraoperative blood loss was uniformly 20 mL.The median postoperative drainage du-ration was 3 d(0-4 d),and the median length of hospital stay was 4 d(4-9 d).No Clavien-Dindo grade Ⅲ or higher complications occurred.All the patients had their double-J stents removed at 2 months postoperatively,and pain in the ipsilateral flank,reported preoperatively by all the five patients,was al-leviated.The subjective surgical success rate was 100％.Surgeons reported stable system performance throughout all the procedures,with no instances of mechanical arm interference or visual drift affecting surgical fluency.Conclusion:Preliminary findings indicate that pyeloplasty using the domestically deve-loped CarinaTM modular laparoscopic robotic system is technically feasible and perioperatively safe for the treatment of UPJO.

Background and purpose:Human papilloma virus(HPV)infection status is crucial for diagnosing cervical precancerous lesions and classifying cervical cancer.High-risk(HR)HPV is often linked to P16 protein overexpression,so P16 detection via immunohistochemistry(IHC)is commonly used to assess HPV infection.However,the differences between HPV status and P16 expression remains unclear.An in-depth study of the correlation between HPV and P16 is essential for clinical guidance.Methods:We retrospectively collected clinical and pathological data of cervical lesions from 618 patients diagnosed at the Department of Pathology,Fudan University Shanghai Cancer Center from January 2020 to December 2023(Ethical number:050432-4-2307E).Polymerase chain reaction(PCR)reverse dot hybridization was used to detect HPV including HR and low-risk(LR)subtypes,and immunohistochemistry was used to detect P16 for comparative analysis.Based on different clinical and pathological diagnoses,the sensitivity and specificity of P16 expression in evaluating HPV infection were evaluated.Among the 618 cases of cervical lesions,there were 92 cases of cervical squamous cell carcinoma,257 cases of cervical adenocarcinoma,79 cases of high-grade squamous intraepithelial lesions(HSIL),105 cases of low-grade squamous intraepithelial lesions(LSIL),and 85 cases of chronic cervical inflammation.Results:According to clinical diagnosis,the HR-HPV positive rate in cervical squamous cell carcinoma was 88.0%(81/92),the P16 positive rate was 91.3%(84/92),and the overall consistency rate between P16 and HPV detection was 90.2%(88/92);for HR-HPV infection,the sensitivity and specificity of P16 were 96.3%and 45.5%.The positive rate of HR-HPV in adenocarcinoma was 54.5%(140/257),the positive rate of P16 was 58.8%(151/257),and the overall consistency rate between P16 and HPV detection was 82.5%(212/257);for HR-HPV infection,the sensitivity and specificity of P16 were 87.9%and 76.1%.In HSIL,the HR-HPV positive rate was 75.9%(60/79),the positive rate of P16 was 70.9%(56/79),and the overall consistency rate between P16 and HR-HPV detection was 82.2%(65/79);for HR-HPV infection,the sensitivity and specificity of P16 were 85.0%and 73.7%.In LSIL,the HR-HPV positive rate was 73.3%(77/105),the positive rate of P16 was 8.5%(9/105),and the overall consistency rate between P16 and HR-HPV detection was 33.3%(35/105);for HR-HPV infection,the sensitivity and specificity of P16 were 10.4%and 96.4%.In chronic cervical inflammation,the HR-HPV positive rate was 20%(17/85),the positive rate of P16 was 0.0%(0/85);for HR-HPV infection,the sensitivity and specificity of P16 were 0.0%and 100.0%.There was a significant positive correlation between P16 positivity and HPV16/18 in cervical squamous cell carcinoma,adenocarcinoma,and HSIL(P=0.000),while there was no significant correlation in LSIL and chronic cervical inflammation(P＞0.05).Conclusion:In cervical squamous cell carcinoma and adenocarcinoma,the consistency of P16 expression and HPV DNA positivity are high,especially in HPV16/18 subtype.There is a good concordance between HR-HPV positivity and P16 protein overexpression.The positive expression of P16 in HSIL may initially reflect HPV infection status.However,in LSIL and chronic cervicitis,P16 expression may not accurately correlate with HPV infection.The inconsistency between P16 and HPV DNA testing could be influenced by multiple factors,including HPV subtypes,histopathological categories,specimen quality,and technical limitations.In clinical practice,it is recommended to conduct comprehensive analysis or employ multiple diagnostic methods to confirm HPV infection status for precise evaluation.

BACKGROUND:Bone marrow mesenchymal stem cells are one of the sources of adipocytes and express all renin-angiotensin system components,but the effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipose tissue is not clear.OBJECTIVE:To observe the effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipose tissue and investigate the role of angiotensin 1a receptor knockout in effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipocytes and its potential mechanisms.METHODS:After isolation and culture of bone marrow mesenchymal stem cells in wild-type and angiotensin 1a receptor knockout SD rats,the cells were cultured to the third generation and randomly divided into four groups:wild type group,knockout group,wild type+angiotensin Ⅱ group,and knockout+angiotensin Ⅱ group.The differentiation was induced in the brown fat induced differentiation medium for 14 days.Angiotensin Ⅱ(100 nmol/L)was added for intervention when the differentiation medium was changed each time in the latter two groups.Western blot assay,qRT-PCR,immunofluorescence,and other methods were used to detect the expression of induced differentiation,lipolysis,β oxidation,and mitochondrial biogenesis in brown fat.RESULTS AND CONCLUSION:Angiotensin Ⅱ could inhibit the browning of rat bone marrow mesenchymal stem cells.Knockout of angiotensin 1a receptor could improve the inhibitory effect of angiotensin Ⅱ on brown lipid formation of rat bone marrow mesenchymal stem cells by promoting lipolysis,enhancing fatty acid β oxidation,promoting mitochondrial biogenesis,and enhancing mitochondrial function.These findings provide new research directions and potential therapeutic targets for obesity treatment,revealing the important role of renin angiotensin systems in fat metabolism and its potential as a therapeutic target.
