ObjectiveTo investigate the status and influencing factors of the continuity of care needs in patients with ruptured intracranial aneurysm hemorrhage. MethodsFrom January, 2022 to April, 2025, 121 patients with ruptured intracranial aneurysm hemorrhage admitted to the Fourth Affiliated Hospital of Anhui Medical University were selected. A questionnaire survey was conducted using general information questionnaire and continuity of care needs questionnaire. Multiple linear regression analysis was used to analyze the influencing factors of continuity of care needs. ResultsA total of 121 questionnaires were distributed, with 115 returned (95.04%). The scores of continuity of care needs were with an average score of (100.54±6.97). Statistically significant differences were observed in scores of continuity of care needs among patients with different ages, education levels, primary family caregivers, preoperative Hunt-Hess grades, number of comorbid diseases, whether they received postoperative rehabilitation training and availability of nearby healthcare services (|F| > 8.104, |t| > 2.651, P < 0.05). Multiple linear regression analysis showed that education level, primary family caregiver, preoperative Hunt-Hess grade, number of comorbid diseases and availability of nearby healthcare services were all influencing factors for the continuity of care needs in patients with ruptured intracranial aneurysm hemorrhage (|t| > 1.703, P < 0.05). ConclusionThe need for continuous care in patients with ruptured intracranial aneurysms is influenced by factors such as educational level, primary family caregivers, preoperative Hunt-Hess grade, number of comorbid diseases and accessibility to nearby healthcare services. Medical staff should comprehensively consider patients' specific conditions and actual needs to provide targeted continuous care services.

Objective To explore the predictive value of peripheral blood cells in the efficacy of neoadjuvant immunotherapy combined with chemotherapy for esophageal squamous cell carcinoma. Methods A retrospective study was conducted on patients with esophageal squamous cell carcinoma (clinical stages Ⅱ-Ⅳa) who underwent neoadjuvant immunotherapy combined with chemotherapy at the Department of Thoracic Surgery, Affiliated Hospital of North Sichuan Medical College from April 2020 to November 2023. According to whether the pathology was completely relieved after treatment, patients were divided into a pathological complete remission group and a pathological incomplete remission group. The College of American Pathologists criteria were used to evaluate the tumor pathological regression grade (TRG) after neoadjuvant therapy (TRG=0, 1 defined as a good efficacy group, TRG=2, 3 defined as a poor efficacy group). Results A total of 92 patients with esophageal squamous cell carcinoma were collected, including 72 males and 20 females. The average age was (65.86±7.66) years. The complete remission of pathology was closely related to the number of lymphocytes in the blood before treatment (P=0.019). The area under the curve (AUC) for predicting complete remission of esophageal squamous cell carcinoma after neoadjuvant immunotherapy combined with chemotherapy was 0.678, the maximum Youden index was 0.328, and the optimal cutoff value was 1.845. The incidence of postoperative pulmonary infection in the pathological incomplete remission group was higher than that in the pathological complete remission group (25.0% vs. 5.6%, P=0.030). Using the optimal cutoff value, there were statistically significant differences in pathological N stage and pathological TNM stage between patients with lymphocyte counts <1.845×109/L and ≥1.845×109/L (P<0.05). Treatment response (by TRG) was significantly associated with the pretreatment red blood cell count (P=0.009). The AUC for predicting a good TRG response was 0.669, with a maximum Youden index of 0.385 and an optimal cutoff value of 4.235. Between the good and poor response groups, there were statistically significant differences in postoperative pathological T stage (P<0.001), N stage (P=0.041), and TNM stage (P＜0.001). When stratified by the optimal cutoff value, there were statistically significant differences in age (P＜0.001) and the prevalence of hypertension (P=0.022) between patients with red blood cell counts <4.235×1012/L and ≥4.235×1012/L. Conclusion A pretreatment absolute lymphocyte count ≥1.845×109/L and a red blood cell count <4.235×1012/L are good predictors for pathological complete response and a good pathological response, respectively, following neoadjuvant immunotherapy combined with chemotherapy in patients with esophageal squamous cell carcinoma.

ObjectiveTo analyze the epidemiological characteristics of a local dengue fever cluster outbreak in Qingpu District of Shanghai in 2024, and to provide a reference for subsequent dengue fever prevention and control. MethodsSeven confirmed local dengue fever cases reported through the National Notifiable Infectious Diseases Surveillance System in Qingpu District of Shanghai in 2024 were selected as the research subjects. Descriptive epidemiological methods were used to conduct investigation and analysis from the aspects of onset, medical treatment and reporting, clinical symptoms, travel and contact history within 15 days before onset, and activity trajectories. ResultsA total of 7 cases were identified in this outbreak. None of the cases had a travel history to dengue-endemic areas within 15 days prior to onset, while all had shared exposure environments and mosquito bite histories, indicating a local clustered transmission pattern. The main clinical manifestations included fever (100.00%) and myalgia (42.86%). All 7 cases were positive for dengue virus serotype 2 (DENV-2) by nucleic acid testing. Genetic sequencing showed that the virus strains belonged to the Cosmopolitan genotype and were most closely related to the epidemic DENV strains circulating in southern China in recent years. ConclusionThis outbreak might be a local secondary infection caused by the short-term stay of dengue fever-infected individuals, and the possible source of importation was dengue fever endemic areas in southern China.

ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective To investigate the regulatory effect of lipocalin 2(LCN2)on epidermal growth factor receptor(EGFR)phosphorylation and its impact on inflammatory damage in human fallopian tube epithelial cells.Methods Human fallopian tube epithelial cells were isolated and a lipopolysaccharide(LPS)intervention was applied to establish an in vitro cell model.The cells were randomly assigned into the following groups:a blank control group(Control),a model group(Model),experimental groups(Model+si-LCN2 or Model+oe-LCN2),and negative control groups(Model+si-NC or Model+oe-NC).Changes in cell viability,apoptosis rates,inflam-matory levels,as well as the expression of EGFR mRNA,LCN2,EGFR,p-EGFR,and the ratio of p-EGFR/EGFR proteins were evaluated.Results Compared to the Model group,the Model+si-LCN2 group exhibited enhanced cell viability,a reduced apoptosis rate,and decreased expression of inflammatory factors(P＜0.05).Immunopre-cipitation analysis confirmed a direct interaction between LCN2 and EGFR.In comparison with the Model group,the Model+oe-LCN2 group demonstrated elevated levels of p-EGFR and the p-EGFR/EGFR ratio(P＜0.05),while no significant change was observed in total EGFR expression(P＞0.05).Conclusion Inhibition of LCN2-mediated EGFR phosphorylation enhances cell viability,reduces apoptosis,and mitigates inflammatory responses,thereby ameliorating LPS-induced inflammatory injury in human fallopian tube epithelial cells.

Objective:To explore the applicability of modified comprehensive interventions in the treatment of non-severe dry eye syndrome in military pilots.Methods:A total of 88 military pilots with non-severe dry eye syndrome admitted to the Special Service Department of the 988th Hospital of the Joint Logistic Support Force between December 2021 and December 2023 were divided into an intervention group and a control group using the random number table method, with 44 cases in each. The intervention group received modified comprehensive interventions, while the control group underwent conventional treatment. The Ocular Surface Disease Index (OSDI), break-up time, tear meniscus height, changes in meibomian gland function, and levels of satisfaction of military pilots were compared between the 2 groups. The correlations between the OSDI, break-up time, tear meniscus height and levels of satisfaction were analyzed.Results:Before treatment, there was no significant difference in the OSDI between the 2 groups ( P>0.05). After 4 weeks of treatment, the changes in the OSDI of military pilots were smaller in the intervention group than in the control group ( t=3.21, P=0.002). After 2 and 4 weeks of treatment, the break-up time (both P<0.001) and tear meniscus height ( P<0.001, =0.012) of pilots in the intervention group exceeded those of the control group. In both groups, the break-up time (all P<0.001) and tear meniscus height (all P<0.001) kept increasing after treatment. After 4 weeks of treatment, there were significant differences in the distribution of meibomian gland function between the 2 groups ( Z=-2.55, -2.41, -2.29, P=0.011, 0.016, 0.022). Clinical care, procedure flow, and health education scored higher in the intervention group than in the control group during the survey on levels of satisfaction with the treatment ( t=6.55, 6.77, 3.63, all P≤0.001). The OSDI was negatively correlated with clinical care, procedure flow and health education ( r=-0.286, -0.275, -0.363, P=0.007, 0.010, 0.001) while the break-up time was positively correlated with clinical care and procedure flow ( r=0.248, 0.278, P=0.020, 0.009). Conclusions:The implementation of modified comprehensive intervention measures for dry eye syndrome in military pilots can effectively improve clinical symptoms and leave military pilots more satisfied.

Objective To analyze and compare the efficacy of DNA barcode,i.e.,Cytochrome b(Cytb)and 12S ribosomal RNA(12S rRNA)gene sequences,in the species identification of wildlife.Methods DNA extraction,quantification,PCR amplification of Cytb and 12S rRNA gene fragments,Sanger sequencing,and sequence alignment analysis were performed on ten wildlife samples.Results Both gene fragments were successfully amplified in six samples,while Cytb alone was successfully amplified in 1 sample,and 12S rRNA alone in 3 samples.Sequence analysis indicated that Cytb enabled species-level identification for 6 samples(Gallinula chloropus,Streptopelia orientalis,Phasianus colchicus,Falco naumanni,Myiopsitta monachus and Lynx lynx)and genus-level identification for 1 sample(Lepus).In contrast,12S rRNA achieved species-level identificaggion for 8 samples(Gallinula chloropus,Lepus sinensis,Phasianus colchicus,Myiopsitta monachus,Muntiacus reevesi,Macaca mulatta and Lynx lynx),representing seven species,and genus-level identification for 1 sample(Falco).However,by combining Cytb and 12S rRNA,all samples could be identified to the species level.Conclusion When applying DNA barcodes to wildlife identification,the Cytb and 12S rRNA gene regions analyzed here can effectively identify common species such as Gallinula chloropus and Streptopelia orientalis,but face difficulties in distinguishing closely related species within the same genus.Therefore,when conducting wildlife species identification,it is recommended to use two or more DNA barcode markers.

Objective:To explore the clinical application value of artificial intelligence（AI）-assisted training in enhancing the accuracy of nuchal translucency（NT）identification，standardization of measurement，and diagnostic efficacy for abnormalities among ultrasound residents.Methods:A retrospective collection of 300 standard fetal NT ultrasound images was conducted at the Center for Medical Ultrasound，Suzhou Hospital Affiliated of Nanjing Medical University from January 2018 to June 2024. The AI model performed NT measurements and diagnoses once. Four sonographers of different seniority levels（including two resident physicians）independently conducted NT measurements and diagnoses twice. Prior to the experiment，the middle-age and resident sonographers had uniformly completed traditional theory training. Following the first independent measurements，the two resident sonographers received additional AI-assisted training，after which all 4 sonographers performed the second independent measurements. A fetal medicine expert evaluated blindly all the results and compared the differences in NT recognition accuracy，measurement standard rate and diagnosis accuracy between the middle-age sonographer（traditional training only）and two resident sonographers（traditional + AI-assisted training）.Results:For the middle-aged sonographer who only received traditional lecture-based training，the accuracy of NT recognition，standardization rate of measurement，or diagnostic accuracy were not significantly improved befroe and after the training，and the diffrence was not statistically significant（ χ2=0.189，1.887，0.326；all P>0.05）. In contrast，the second-year resident（Resident 2）and first-year resident（Resident 1），who received both traditional lecture-based training and AI training，demonstrated some improvements in the accuracy of NT measurement site recognition，though the differences were not statistically significant（ χ2=1.301，2.418；all P>0.05）. However，both residents did significant improvements in the standardization rate of NT measurement（ χ2=25.768，17.035；all P<0.05）. In terms of diagnostic accuracy，Resident 1 did significant improvement（ χ2=10.180， P<0.05），while Resident 2 also did some improvement，though the difference was not statistically significant（ χ2=2.573， P>0.05）. Conclusions:The AI-assisted training system enhances the ability of ultrasound resident sonographers to recognize，measure，and diagnose NT，providing a novel and efficient training model for standardized residency training in ultrasound specialties.
