Objective To evaluate the performance of the artificial intelligence (AI)-enabled snail identification system for recognition of Oncomelania hupensis robertsoni and Tricula in schistosomiasis-endemic areas of Yunnan Province. Methods Fifty O. hupensis robertsoni and 50 Tricula samples were collected from Yongbei Township, Yongsheng County, Lijiang City, a schistosomiasis-endemic area in Yunnan Province in May 2024. A total of 100 snail sample images were captured with smartphones, including front-view images of 25 O. hupensis robertsoni and 25 Tricula samples (upward shell opening) and back-view images of 25 O. hupensis robertsoni and 25 Tricula samples (downward shell opening). Snail samples were identified as O. hupensis robertsoni or Tricula by schistosomiasis control experts with a deputy senior professional title and above according to image quality and morphological characteristics. A standard dataset for snail image classification was created, and served as a gold standard for recognition of snail samples. A total of 100 snail sample images were recognized with the AI-enabled intelligent snail identification system based on a WeChat mini program in smartphones. Schistosomiasis control professionals were randomly sampled from stations of schistosomisis prevention and control and centers for disease control and prevention in 18 schistosomiasis-endemic counties (districts, cities) of Yunnan Province, for artificial identification of 100 snail sample images. All professionals are assigned to two groups according the median years of snail survey experiences, and the effect of years of snail survey experiences on O. hupensis robertsoni sample image recognition was evaluated. A receiver operating characteristic (ROC) curve was plotted, and the sensitivity, specificity, accuracy, Youden’s index and the area under the curve (AUC) of the AI-enabled intelligent snail identification system and artificial identification were calculated for recognition of snail sample images. The snail sample image recognition results of AI-enabled intelligent snail identification system and artificial identification were compared with the gold standard, and the internal consistency of artificial identification results was evaluated with the Cronbach’s coefficient alpha. Results A total of 54 schistosomiasis control professionals were sampled for artificial identification of snail sample image recognition, with a response rate of 100% (54/54), and the accuracy, sensitivity, specificity, Youden’s index, and AUC of artificial identification were 90%, 86%, 94%, 0.80 and 0.90 for recognition of snail sample images, respectively. The overall Cronbach’s coefficient alpha of artificial identification was 0.768 for recognition of snail sample images, and the Cronbach’s coefficient alpha was 0.916 for recognition of O. hupensis robertsoni snail sample images and 0.925 for recognition of Tricula snail sample images. The overall accuracy of artificial identification was 90% for recognition of snail sample images, and there was no significant difference in the accuracy of artificial identification for recognition of O. hupensis robertsoni (86%) and Tricula snail sample images (94%) (χ² = 1.778, P > 0.05). There was no significant difference in the accuracy of artificial identification for recognition of snail sample images with upward (88%) and downward shell openings (92%) (χ² = 0.444, P > 0.05), and there was a significant difference in the accuracy of artificial identification for recognition of snail sample images between schistosomiasis control professionals with snail survey experiences of 6 years and less (75%) and more than 6 years (90%) (χ² = 7.792, P < 0.05). The accuracy, sensitivity, specificity and AUC of the AI-enabled intelligent snail identification system were 88%, 100%, 76% and 0.88 for recognition of O. hupensis robertsoni snail sample images, and there was no significant difference in the accuracy of recognition of O. hupensis robertsoni snail sample images between the AI-enabled intelligent snail identification system and artificial identification (χ² = 0.204, P > 0.05). In addition, there was no significant difference in the accuracy of artificial identification for recognition of snail sample images with upward (90%) and downward shell openings (86%) (χ² = 0.379, P > 0.05), and there was a significant difference in the accuracy of artificial identification for recognition of snail sample images between schistosomiasis control professionals with snail survey experiences of 6 years and less and more than 6 years (χ² = 5.604, P_adjusted < 0.025). Conclusions The accuracy of recognition of snail sample images is comparable between the AI-enabled intelligent snail identification system and artificial identification by schistosomiasis control professionals, and the AI-enabled intelligent snail identification system is feasible for recognition of O. hupensis robertsoni and Tricula in Yunnan Province.

Objective: To evaluate the immunogenicity and safety of co-administration with bivalent human papillomavirus (HPV) vaccine and hepatitis E virus (HEV) vaccine, so as to provide reference for optimizing the vaccination schedule. Methods: Females aged 18 to 25 years were recruited from September to October 2021 in Hengdian College of Film & Television in Zhejiang Province and randomly divided into the HPV+HEV group, the HPV group, and the HEV group. The vaccination procedures were one dose each at 0, 1, and 6 months. Immunogenicity was evaluated by detecting the geometric mean titers (GMT) of HPV16 IgG, HPV18 IgG, and/or HEV IgG antibodies before the first vaccination and one month after the full course of immunization, and comparing the difference in seroconversion, and the GMT ratio. The non-inferiority margin was set at a seroconversion difference of ≤5%, and the lower limit of the 95%CI of the GMT ratio was >0.5. Safety was evaluated by collecting conjunctive local reactions/events and systemic reactions/events within 7 days after each dose, non-conjunctive adverse events within 30 days after each dose, and serious adverse events throughout the observation period (0 to 7 months). Results: A total of 240 females were included, among whom 236 completed the full vaccination program, including 79 in the HPV+HEV group, 77 in the HPV group, and 80 in the HEV group. One month after the full course of immunization, the seroconversion rates of HPV16 IgG and HPV18 IgG antibodies in both the HPV+HEV group and the HPV group were 100%, and the differences in seroconversion rates were 0 (95%CI: -3.39%-+∞). The seroconversion rates of HEV IgG antibodies in both the HPV+HEV group and the HEV group were 100%, and the difference in seroconversion rates was 0 (95%CI: -3.27%-+∞). The GMT of HPV16 IgG and HPV18 IgG antibodies in the HPV+HEV group was 393.88 and 284.86 IU/mL respectively, which was not inferior to 489.39 and 341.24 IU/mL in the HPV group, and the GMT ratios were 0.80 (95%CI: 0.66-+∞) and 0.83 (95%CI: 0.68-+∞), respectively. The GMT of HEV IgG in the HPV+HEV group was 13.55 U/mL, which was not inferior to 12.72 U/mL in the HEV group, and the GMT ratio was 1.07 (95%CI: 0.92-+∞). The incidences of pain, pruritus, and induration in the HPV+HEV group were 54.43%, 21.52% and 40.51% respectively, which were significantly higher than 10.39%, 0, and 0 in the HPV group (all P<0.05). The incidences of redness/swelling, muscle pain/general weakness in the HPV+HEV group were 2.53% and 0, respectively, which were significantly lower than 12.50% and 16.25% in the HEV group (both P<0.05). Conclusion The co-administration of the bivalent HPV vaccine and HEV vaccine is not inferior to individual vaccination in terms of immunogenicity and safety, and the vaccination plan can be optimized through co-administration.

Objective To explore the current status and influencing factors of heart failure occurrence in patients with unstable angina pectoris (UAP), and to provide a scientific basis for developing individualized prevention and treatment strategies. Methods A total of 310 patients with UAP admitted to the Fifth People's Hospital from October 2021 to October 2024 were selected as study subjects. The current status of the patients' heart failure was statistically analyzed, and the patients were divided into heart failure group and non-heart failure group according to whether they had heart failure. Univariate and logistic multivariate regression analyses were used to analyze the risk factors for the occurrence of heart failure in patients with UAP. Results Among the 310 patients with UAP, 63 cases had heart failure, with an incidence rate of 20.32%. After logistic multivariate analysis, it was found that diabetes mellitus, hyperlipidemia, number of coronary artery lesions, homocysteine and plasma brain natriuretic peptide levels were risk factors of heart failure in patients with UAP, and hemoglobin level was a protective factor (OR: 2.010, 95%CI: 1.063-3.800; OR: 4.495, 95%CI: 2.228-9.067; OR: 2.408, 95%CI: 1.256-4.617; OR: 3.655, 95%CI: 1.812-7.372; OR: 4.693, 95%CI: 2.622-8.399; OR: 0.359, 95%CI: 0.205-0.628, P<0.05). Conclusion The coronary heart disease risk of heart failure is high in patients with UAP, and is affected by comorbidities, number of coronary artery lesions, homocysteine, and plasma brain natriuretic peptide levels. It is necessary to perform clinical screening and pay attention to such patients, and take active prevention and control interventions.

Objective:To analyze the clinical features, prognosis and risk factors of SARS-CoV-2 associated acute pancreatitis (SAAP), and provide a basis for early prevention and treatment of SAAP.Methods:Patients with coronavirus disease 19 infection (COVID-19) admitted to Zhejiang Provincial People's Hospital from December 1, 2022 to January 31, 2023 were retrospectively analyzed. Clinical characteristics such as age, gender and other data were recorded, and the indexes of blood routine, liver and kidney function, inflammatory factor, coagulation function, blood gas analysis, immunoglobulin and complement were collected after admission. Patients were divided into pancreatic injury group and non-pancreatic injury group according to the level of serum amylase/lipase. The difference of prognosis and related hematological parameters between the two groups was compared. Multifactorial logistic regression equation was constructed to analyze the risk factors of SAAP.Results:A total of 2 101 patients with COVID-19 who met the criteria were included, including 298 patients in the pancreatic injury group and 1 803 patients in the non-pancreatic injury group. 17 cases (5.7%) in the pancreatic injury group met the diagnostic criteria for AP. The age, male percentage and mortality rate of the pancreatic injury group were all significantly higher than those of the non-pancreatic injury group (all P<0.05). In the pancreatic injury group, white blood cell count, neutrophil-to-lymphocyte ratio, C-reactive protein (CRP), calcitoninogen, erythrocyte sedimentation rate, inflammatory cytokines, tumour necrosis factor, liver and kidney functions, coagulation (D-dimer and plasma fibrinogen degradation products), and lactate level were significantly higher than those in the non-pancreatic injury group (all P<0.05). Serum complement C3, albumin, albumin globule ratio and arterial oxygenation index were lower in the pancreatic injury group (all P<0.05). Multifactorial logistic regression analysis showed that gender, age, CRP, calcitoninogen, total bilirubin, creatinine, PaO 2, PaO 2/FiO 2 and lactate were independent risk factors for the occurrence of pancreatic injury in patients with COVID-19 (all P<0.05). Conclusions:Inflammation-related markers, D-dimer and fibrinogen degradation products were significantly higher in COVID-19 patients comorbid with pancreatic injury than in the patients without pancreatic injury. The risk of SAAP was significantly higher in male patients of senior age. Sex, age, CRP, calcitoninogen, total bilirubin, creatinine, oxygenation index, and lactic acid were independent risk factors for the onset of pancreatic injury in COVID-19 patients.

Objective:To identify early potential risk factors for sepsis-associated liver injury and to provide a reference for early clinical identification and intervention.Methods:The clinical data of septic patients admitted to the intensive care unit (ICU) in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from March 2020 to April 2023 were retrospectively analyzed. Patients with sepsis were categorized into the liver injury group and the non-liver injury group according to whether liver injury occurred or not, univariate and multivariate logistic regression analyses were used to explore the risk factors for SALI, receiver operating characteristic (ROC) curve analysis was used to assess its predictive effect for SALI, and performed subgroup analyses basing on the cut-off point.Results:Among 530 eligible patients, 403 patients were included. The incidence of liver injury was 39.45% in 159 cases with liver injury and 244 cases without liver injury. Multivariate logistic regression analysis showed that serum prealbumin, lactate and lactate dehydrogenase were independent risk factors for SALI. ROC curve analysis showed that all single indicators had some predictive value for SALI, the area under the curve was prealbumin (AUC: 0.752, 95% CI: 0.703-0.801), lactate (AUC: 0.679, 95% CI: 0.627-0.732), lactate dehydrogenase (AUC: 0.664, 95% CI: 0.611-0.718), respectively, The AUC for predicting SALI by lactate/prealbumin ratio (L/P) and lactate dehydrogenase/prealbumin ratio were 0.808 (95% CI: 0.766-0.850) and 0.795 (95% CI: 0.750-0.840), respectively, with the best efficacy of L/P in predicting SALI. Subgroup analyses showed that the incidence of liver injury was significantly higher in septic patients with L/P ≥0.23 than that in septic patients with L/P <0.23, at the same time, the acute physiology and chronic health evaluation II score, shock probability, and hospital mortality rate also increased accordingly, the differences were all statistically significant (all P < 0.001). Conclusions:L/P is early independent risk factor of SALI, for sepsis patients with L/P≥0.23 should be alerted to the development of liver injuryis.

Objective:To compare the prevalence and progression of subclinical atherosclerosis (SA) in populations with different cardiovascular disease (CVD) risks in China, and clarify the relationship between CVD risk stratification and SA.Methods:All participants were from Beijing Community-Based Cohort of Atherosclerosis. A total of 1 462 participants underwent carotid ultrasound and coronary computed tomography scan during 2008-2009 and 2013-2014. After excluding 191 participants with history of CVD and incomplete baseline data, 1 271 participants were included in final analysis. The 10-year CVD risk for participants were calculated based on the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) equation, and risk stratification was performed. The prevalence and progression of SA was determined by carotid intima-media thickness (cIMT), carotid plaque score and coronary artery calcification (CAC) score.Results:In the participants included in this study, 536 (42.2%), 418 (32.9%) and 317 (24.9%) were classified to have low, intermediate and high 10-year risk, respectively. With the rising level of 10-year risk, the proportion of patients with SA and SA progression increased. In low, intermediate and high CVD risk groups, the proportions of participants with CAC were 16.4%, 36.4% and 52.0% (trend P<0.001); and 15.4%, 36.4% and 53.6% had progression of CAC during follow-up, respectively (trend P<0.001); compared with low-risk group, RRs for CAC progression of intermediate and high-risk groups were 2.316 (95% CI: 1.714-3.129) and 3.322 (95% CI: 2.472-4.463), respectively (trend P<0.001). The trend of relationship between CVD risk stratification and cIMT and carotid plaque progression were consistent with CAC. Conclusions:This current study shows CVD risk stratification is closely related to the prevalence and progression of atherosclerosis in Chinese population. However, many people with low CVD risk have atherosclerotic change in their carotid and coronary artery.

Postoperative pulmonary complications and anastomotic leakage are unfavorable prognostic factors in patients with esophageal carcinoma.However,the prognostic importance of pulmonary complications and anastomotic leakage after neoadjuvant treatment in these patients remains unclear.This study aimed to determine the effect of postoperative pulmonary complications and anastomotic leakage on long-term survival after neoadjuvant therapy for esophageal cancer.Our study were recruited 441 consecutive patients who had curative resection following neoadjuvant treatment for esophageal cancer in our institution from 2011-2021.The clinicopathological characteristics and prognosis of these patients were studied in terms of postoperative pulmonary complications and anastomotic leaking.Survival was analyzed using the log-rank test and multivariable Cox regression analysis.Postoperative pulmonary complications and anastomotic leakage were present in 23.8％(n=105)and 5.2％(n=23)of esophageal cancer after neoadjuvant therapy,respectively.In the univariate analyses,pulmonary complications were associated with shorter disease-free survival,while anastomotic leakage was associated with shorter overall survival.Multivariable analysis revealed that pulmonary complications after neoadjuvant therapy were independent adverse prognostic factors for disease-free survival.Taken together,postoperative pulmonary complications and anastomotic leakage ware significantly negatively correlated with disease-free and overall survival,respectively.And the postoperative pulmonary complication is an independent poor prognostic factor of disease-free survival for esophageal cancer following neoadjuvant treatment.
