Objective To investigate the effectiveness of the integrated schistosomiasis control programme in Sichuan Province during the stage moving from transmission interruption to elimination (2015—2023), so as to provide insights into formulation of the schistosomiasis control measures during the post-elimination stage. Methods Schistosomiasis control data were retrospectively collected from departments of health, agriculture and rural affairs, forestry and grassland, water resources, and natural resources in Sichuan Province from 2015 to 2023, and a database was created to document examinations and treatments of human and livestock schistosomiasis, and snail survey and control, conversion of paddy fields to dry fields, ditch hardening, rivers and lakes management and building of forests for snail control and schistosomiasis prevention. The completion of schistosomiasis control measures was investigated, and the effectiveness was evaluated. Results A total of 20 545 155 person-times received human schistosomiasis examinations in Sichuan Province during the period from 2015 to 2023, and 232 157 person-times were seropositive, with a reduction in the seroprevalence from 2.10% (44 299/2 107 003) in 2015 to 1.12% (9 361/837 896) in 2023 (χ² = 7.68, P < 0.001). The seroprevalence of human schistosomiasis appeared a tendency towards a decline in Sichuan Province over years from 2015 to 2023 (b = −8.375, t = −10.052, P < 0.001); however, no egg positive individuals were identified during the period from 2018 to 2023, with the prevalence of human Schistosoma japonicum infections maintained at 0. Expanded chemotherapy was administered to 2 754 515 person-times, and medical assistance of advanced schistosomiasis was given to 6 436 persontimes, with the treatment coverage increasing from 46.80% (827/1 767) in 2015 to 64.87% (868/1 338) in 2023. Parasitological tests for livestock schistosomiasis were performed in 35 113 herd-times, and expanded chemotherapy was administered to 513 043 herd-times, while the number of fenced livestock decreased from 121 631 in 2015 to 103 489 in 2023, with a reduction of 14.92%. Snail survey covered 433 621.80 hm² in Sichuan Province from 2015 to 2023, with 204 602.81 hm² treated by chemical control and 4 637.74 hm² by environmental modifications. The area of snail habitats decreased from the peak of 5 029.80 hm² in 2016 to 3 709.72 hm² in 2023, and the actual area of snail habitats decreased from the peak of 8 585.48 hm² in 2016 to 473.09 hm² in 2023. The mean density of living snails remained low across the study period except in 2017 (0.62 snails/0.1 m²). Schistosomiasis control efforts by departments of agriculture and rural affairs in Sichuan Province included conversion of paddy fields to dry fields covering 153 346.93 hm², hardening of 6 110.31 km ditches, building of 70 356 biogas digesters, replacement of cattle with 227 161 sets of machines, and captive breeding of 21 161 070 livestock from 2015 to 2023, and the control efforts by departments of water resources included rivers and lakes management measuring 5 676.92 km and renovation of 2 331 irrigation areas, while the control efforts by departments of forestry and grassland included building of forests for snail control and schistosomiasis prevention covering 23 913.33 hm², renovation of snail control forests covering 8 720 hm² and newly building of shelterbelts covering 764 686.67 hm². All 63 endemic counties (cities and districts) had achieved the criterion for schistosomiasis elimination criteria in Sichuan Province by the end of 2023. Conclusion Following the integrated control efforts from 2015 to 2023, remarkable achievements have been obtained in the schistosomiasis control programme in Sichuan Province, with all endemic counties successfully attaining the schistosomiasis elimination target at the county level.

OBJECTIVE To investigate the improvement effect and mechanism of desloratadine citrate disodium in mice with hypersensitivity pneumonitis （HP）. METHODS Sixty mice were randomly divided into blank control group （normal saline）， model group （normal saline）， prednisone group （positive control， 20 mg/kg） and desloratadine citrate disodium low-， medium- and high-dose groups （0.5， 1， 2 mg/kg）， with 10 mice in each group. Except for the blank control group， mice in other groups were intraperitoneally injected with ovalbumin （OVA） and exposed to OVA inhalation to establish the HP model. On day 22 post- modeling， mice in each group were administered the corresponding drugs or normal saline， once a day， for 11 consecutive days. After the last administration， lung function and airway hyperreactivity were assessed. The levels of interleukin-1β （IL-1β）， IL-4 and IL-6 in serum as well as the levels of IL-8， IL-13 and IL-17A in bronchoalveolar lavage fluid were determined. Pathological changes in lung tissue of mice were evaluated using Masson staining. Furthermore， the expressions of fibrosis-related proteins， including transforming growth factor β1 （TGF-β1）， type Ⅲ collagen （Col-Ⅲ） and fibronectin （FN） were determined in lung tissues. RESULTS Compared with the blank control group， the model group showed significant deterioration in lung function （P＜ 0.01）， while airway resistance and serum levels of IL-1β， IL-4， IL-6 and the levels of IL-8， IL-13 and IL-17A in the bronchoalveolar lavage fluid were increased significantly （P＜0.01）. The lung tissues exhibited alveolar collapse， atrophy， and structural disarray， along with the formation of extensive deposits of blue collagen fibers， the percentage of positive staining increased significantly （P＜0.01）. Additionally， the expression levels of TGF-β1， Col-Ⅲ， and FN proteins in the lung tissues were also increased significantly （P＜0.01）. After intervention with desloratadine citrate disodium， the pathological changes in the lung tissues of mice in each dosage group of desloratadine citrate disodium showed varying degrees of improvement， and most of the aforementioned indicator levels were significantly reversed （P＜0.05 or P＜0.01）. CONCLUSIONS Desloratadine citrate disodium can improve the lung function and airway hyperreactivity of HP mice， inhibit the release of inflammatory factors in serum and bronchoalveolar lavage fluid， and reduce the deposition of collagen fibers. Its mechanism of action may be related to anti-inflammatory， immunomodulatory， and antifibrotic effects.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective To investigate the effect of fear-induced stress during pregnancy on the expression of glucose transporters(GLUT)in the placenta,providing evidence for the theory of fetal damage caused by fear-induced stress during pregnancy.Methods Twenty pregnant Wistar rats were randomly divided into a control group and a model group of 10 rats each.In the model group,a fear-induced stress model was established using the modified bystander electroshock method for 20 days.After the experiment,the number of offspring and the weights of the placenta and fetal rats were measured,and the placental efficiency was calculated.Transmission electron microscopy was used to observe the morphological changes of placental cells.Bioinformatics analysis was performed to screen for differential genes in placentas affected by pregnancy stress-phobia,and gene set enrichment analysis was performed.Protein immunoblotting(Western Blot),Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR),and immunohistochemistry were used to detect the expression levels of GLUT1,GLUT3,GLUT6,and GLUT7 proteins and genes.Results The placental efficiency was significantly reduced in the model group compared with that in the control group.The result of transmission electron microscopy in the model group showed that the placental microvilli were sparse and short and that the mitochondria and endoplasmic reticulum were swollen.Gene set enrichment analysis revealed that placental genes were significantly enriched in cellular glucose homeostasis in the model group compared with those in the control group.The result of Western Blot,Real-time PCR,and immunohistochemistry indicated a decrease in both the protein and gene expression levels of GLUT1,GLUT6,and GLUT7 in the placenta of pregnant rats.Conclusions Prenatal exposure to fear-induced stress may lead to adverse pregnancy outcomes.These adverse outcomes are potentially associated with reduced levels of three key GLUTs in the placenta:GLUT1,GLUT6,and GLUT7.

Objective To investigate the effects and mechanisms of five-element music on the social behavior of the children of mothers with fear stress during pregnancy and provide a basis for the early prevention and treatment of clinical fetogenic affective disorders.Methods Forty-five pregnant mice were randomly divided into three groups:a control group,model group,and five-element music group.The model and five-element music group models were established using the bystander electric shock method.Additionally,the five-element music group was exposed to Palace Tune five-element music daily from 17:00 to 19:00 during pregnancy.On the 19th day of pregnancy,ELISA was employed to assess the levels of adrenocorticotropin(ACTH)and cortisol(CORT)in the serum of pregnant mice in each group for modeling evaluation.The offspring were subsequently grouped with their mother and underwent an 8-week-old three-box social experiment to observe their social behavior.We used the immunofluorescence double-labeling method to detect glutamatergic neuron activity in the medial prefrontal cortex(mPFC)of the offspring.High-performance liquid chromatography was employed to measure the total glutamate(Glu)content in the mPFC,while Gorky staining was used to observe changes in the dendritic spines of mPFC neurons in the offspring.Results Compared to those in the blank group,pregnant mice in the model group exhibited a significant increase in the levels of ACTH and CORT in their serum,and there was a significant decrease in the social interaction time and social novelty preference index of their offspring.There was also a significant decrease in glutamate neuron activity,glutamate content,and neuronal dendritic spine density.In contrast,compared with those in the model group,pregnant mice in the five-element music group demonstrated a reduction in the levels of ACTH and CORT in the serum,and there were improvements in the social behavior,glutamate neuron activity,glutamate content,and condition of neuronal dendritic spines in the offspring.Conclusions Intervention with five-element music effectively ameliorated the offspring's social behavior disorder result ing from prenatal fear stress;the mechanism was potentially linked to enhanced glutamate neuron activity in the mPFC region.

Objective To explore clinical effect of Jiawei Sangju decoction combined with oseltamivir in the treatment of influenza B complicated with benign acute childhood myositis(BACM).Methods Sixty children with influenza B complicated with BACM hospitalized in the Department of Pediatrics,Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2021 to January 2024 were selected and divided into control group and study group according to random number table method,with 30 cases in each group.The control group was treated with oseltamivir,and the study group was treated with Jiawei Sangju decoction combined with oseltamivir.The clinical efficacy,symptom improvement time and aspartate transaminase(AST),alanine transaminase(ALT),creatine kinase(CK),creatine kinase isozyme(CK-MB),lactate dehydrogenase(LDH)and myoglobin(Mb)before and after treatment were compared between two groups.Results After treatment,the total effective rate of study group was significantly higher than that of control group(χ2=5.455,P=0.020).The duration of fever and leg pain relief in study group were significantly shorter than those in control group(P<0.05).After 5 days of treatment,the levels of AST,CK,CK-MB,LDH and Mb in two groups were significantly lower than before treatment(P<0.05),and the levels of AST,CK,CK-MB,LDH and Mb in study group were significantly lower than those in control group(P<0.05).Conclusion Jiawei Sangju decoction combined with oseltamivir can improve the symptoms of influenza B with BACM,reduce the levels of muscle enzyme and Mb,and have a positive effect on the prognosis of children.

Objective To investigate the status quo and its influencing factors of nurses'organizational silence in 3 Grade A general hospitals.Methods Convenient sampling method was used to investigate clinical nurses in 3 Grade A general hospitals in Xi'an from April to August 2023 by general data questionnaire,nurses'organizational silence questionnaire and hospital magnetic factor scale.Multiple linear regression was used to analyze the influencing factors of organizational silence.Results A total of 855 nurses completed the study.The total silence score of nurses was(56.33±8.55);The total score of hospital magnetic level was(107.63±12.85).There was a negative correlation between nurse tissue silence and hospital magnetic level(r=-0.318,P<0.01).Hospital magnetic level,age,job title and working time were the influential factors of nurses'organizational silence(all P<0.001),which together explained 62.60%of the variation.Conclusions The silence of nurses'tissue and the level of hospital magnetism are in the low-medium level.Nurses are younger in age,lower in professional title,shorter in nursing age and lower in hospital magnetism level,the higher the tissue age level is,the nursing managers can reduce the tissue silence of nurses by improving the hospital magnetism level.

Objective To investigate the value of quantitative CT(QCT)parameters related to abdominal and dorsal fat content for predicting early postoperative complications of esophageal cancer.Methods A total of 184 patients who underwent radical esophageal cancer surgery were retrospectively collected and divided into complication group(n=76)and control group(n=108)according to whether early postoperation complication(within 30 days after surgery)occurred or not.QCT was used to obtain parameters related to abdominal and dorsal fat content,including visceral fat area(VFA),subcutaneous fat area(SFA),VFA/SFA and the degree of muscle fat infiltration(MFI)of posterior vertebral muscles based on L3 central-level CT images.Univariate analysis and multivariate logistic regression were used to analyze clinical and pathological data as well as QCT parameters related to abdominal and dorsal fat content to screen independent risk factors for early postoperative complications of esophageal cancer.Then receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of each independent risk factor alone and their combination for predicting early postoperative complications of esophageal cancer.Results VFA/SFA and MFI degree of posterior vertebral muscles were both independent risk factors for early postoperative complications of esophageal cancer(OR=5.121,1.110,both P＜0.05).The AUC of VFA/SFA and MFI degree of posterior vertebral muscle was 0.81 and 0.77,respectively,while of their combination was 0.84.Conclusion QCT parameters related to abdominal and dorsal fat content could be used to effectively predict early complications of esophageal cancer after surgery.

Objective:To investigate the value of multimodal ultrasound features combined with peripheral blood inflammatory cell ratios in evaluating the efficacy of neoadjuvant chemotherapy (NAC) in breast cancer.Methods:A total of 106 breast cancer patients diagnosed and treated with NAC at the Second Affiliated Hospital of Anhui Medical University from May 2021 to April 2024 were retrospectively collected, resulting in the conclusion of 61 patients (61 masses) in the study. All patients underwent multimodal ultrasound and peripheral blood routine examinations before NAC and after two cycles of NAC treatment. The patients were divided into a major histological response (MHR) group and a non-major histological response (NMHR) group as indicators for evaluating NAC efficacy. The differences in multimodal ultrasound features and inflammatory cell ratios before NAC and after two cycles of NAC treatment between the MHR and NMHR groups were compared. Binary logistic multivariate regression analysis was performed to determine the independent predictors of NAC efficacy in breast cancer. ROC curves were plotted to evaluate the diagnostic efficacy of predicting NAC efficacy.Results:Among the 61 breast masses, 25 (40.98%) were in the MHR group, and 36 (59.02%) were in the NMHR group.Multivariate binary logistic regression analysis showed that the change rate of maximum tumor diameter after the second cycle (ΔD 2), change rate of vascular index after the second cycle (ΔVI 2), change rate of elastic strain ratio after the second cycle (ΔE-Strain 2), change rate of reverse imaging score after the second cycle (ΔI-imaging score 2), and platelet-to-lymphocyte ratio (PLR) before NAC were independent predictors of NAC efficacy ( OR=1.145, P=0.019; OR=1.055, P=0.016; OR=1.036, P=0.033; OR=1.276, P=0.016; OR=1.054, P=0.047). The area under the ROC curve (AUC) for the combined diagnosis of the above parameters was 0.928 (95% CI=0.866~0.990), with a sensitivity of 80.0% and a specificity of 91.7%. Conclusions:The combination of ΔD 2, ΔVI 2, ΔE-Strain 2, ΔI-imaging score 2 and PLR before NAC has high clinical application value for early prediction of NAC efficacy in breast cancer.
