Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

OBJECTIVE: To block family transmission of a small fragment copy number variation (CNV) with combined 1 Mb resolution preimplantation genetic testing for aneuploidy (PGT-A) and target region preimplantation genetic testing for monogenic disease (PGT-M) strategies. METHODS: A couple who attended the Reproductive and Genetic Medicine Center of Dalian Women and Children's Medical Center (Group) in 2024 were selected as the study subject. Upon the woman's two pregnancies, ultrasound examination revealed fetal abnormalities, and CNV-seq based on low-depth whole genome sequencing revealed that both fetuses had carried a maternal 17p12 microduplication of approximately 1.43 Mb. Microduplication in this region has been associated with Charcot-Marie-Tooth disease type 1A. In view of the fact that the resolution of conventional PGT-A detection cannot meet the requirement of small fragment CNV analysis, and conventional PGT-M assay cannot directly determine the CNV, two detection schemes were adopted. On the one hand, PGT-A testing with 1 Mb resolution was performed on the embryo to directly determine whether it carries the above microduplication. At the same time, the couple and their fetus were subjected to chromosomal typing scheme for the 17p12 region to indirectly identify embryos carrying the risk chromosome for microduplication. This study has been approved by the Medical Ethics Committee of the Hospital (Ethics No: FEJT-KY-2025-51). RESULTS: Three embryos were tested after the first PGT cycle, of which 1 was not carrying the pathogenic variant and was euploid, whilst the other 2 embryos were carrying the 17p12 microduplication, and 1 of them was aneuploid. After genetic counseling, the euploid embryo without the 17p12 microduplication was selected for transfer, and prenatal diagnosis based on amniotic fluid sample showed that the fetal chromosomal karyotype was normal and did not carry the 17p12 microduplication. CONCLUSION The combined application of high-resolution PGT-A and PGT-M typing detection of the target region can effectively block family transmission of the CNVs of small fragments.

The first level indexes included medical quality and medical cost, with relative weights of 66.67% and 33.33%, respectively. Among them, medical quality included 7 secondary indexes: medical management, medical safety, service mode, information construction, patient outcomes, service efficiency, and satisfaction; Medical costs include 2 secondary indiexes: patient costs and medical institution costs.Conclusions:The evaluation index system for the efficiency of perioperative medical services reflected the connotation of value-based healthcare and could comprehensively and objectively evaluate the efficiency of perioperative medical services.

Objective:To investigate the influence of combining therapy of massage on sacro-2 to sacro-4 spinal cord reflexion area and anal dilatation therapy on constipation after cerebral apoplexy and promote the rehabilitation of defecation function in patients with constipation after stroke.Methods:Aandomized controlled study method was chosen, 80 patients with constipation after cerebral apoplexy treated in Guangzhou Traditional Chinese Medicine Hospital from August 2018 to July 2019 were selected as research subjects by convenience sampling. The enrolled patients were divided into 2 groups, 40 to the observation group and 40 to the control group by random number table method. On the basis of routine constipation related nursing measures, the control group was given anal dilatation therapy, while the observation group′s treatment was given massage on sacro-2 to sacro-4 spinal cord reflexion area combined with anal dilatation therapy. Before intervention and after intervention, the changes of therapeutic effect of constipation effect, constipation symptoms scores and the degree of neurological deficit were all compared between the two groups.Results:There were 22 males and 18 females in the observation group; age ranged from 40 to 75 (63.33 ± 8.49) years old; in the control group, there were 23 males and 17 females, aged 41-74 (63.03 ± 7.60) years old. Before intervention, there was no statistically significant difference in constipation symptom scores and neurological deficits between the two groups (both P>0.05). After intervention, the score of constipation symptoms was (3.80 ± 2.05) points and the score of the degree of neurological deficit was (7.58 ± 2.69) points in the observation group, both lower than (5.18 ± 3.52) points and (8.90 ± 2.73) points in the control group with statistically significant differences between the two groups ( t values were respectively -2.13 and -2.19, both P<0.05). The total efficacy of the observation group was 97.50% (39/40), which was significantly higher than 87.50% (35/40) of the control group with statistically significant differences between the two groups ( χ2 = - 2.11, P<0.05). Conclusions:Nursing intervention of massage on sacro-2 to sacro-4 spinal cord reflexion area combined with anus dilatation therapy on constipation after cerebral apoplexy can effectively reduce the symptoms of constipation and lowered the degree of neurological deficit, which is beneficial to the functional rehabilitation of patients with cerebral apoplexy.

Objective:To investigate the value of nomogram based on radiomics features of CT enterography (CTE) combined with clinical characteristics to predict secondary loss of response (SLOR) after infliximab (IFX) treatment in patients with Crohn′s disease (CD).Methods:This study was a case-control study. Clinical and imaging data of 155 patients with CD diagnosed at the First Affiliated Hospital of Anhui Medical University from March 2015 to July 2022 were retrospectively collected. The patients were divided into a training set ( n=108) and a testing set ( n=47) in the ratio of 7∶3 by stratified sampling method. All patients were treated according to the standardized protocol and were classified as SLOR (43 in the training set and 18 in the testing set) and non-SLOR (65 in the training set and 29 in the testing set) according to treatment outcome. Based on the data from the training group, independent clinical predictors of SLOR after IFX treatment were screened in the clinical data using univariate and multivariate logistic regression analysis to establish a clinical model. Intestinal phase images were selected to be outlined layer by layer along the margin of the lesion to obtain the volume of the region of interest to extract the radiomics features. The radiomics features were screened using univariate analysis and the minimum absolute shrinkage and selection operator to establish the radiomics model. Multivariate logistic regression analysis was used to build a combined clinical-radiomics model based on the screened clinical independent predictors and radiomics characters, then a nomogram was drawn. The predictive efficacy of the 3 models for SLOR after IFX treatment was assessed by receiver operating characteristic curves, and the area under the curve (AUC) was calculated. The decision curve analysis was applied to evaluate the clinical utility of the models. Results:Disease duration ( OR=1.983, 95% CI 1.966-2.000, P=0.046) and intestinal stenosis ( OR=1.246, 95% CI 1.079-1.764, P=0.015) were identified as the independent predictors of SLOR in the clinical data, and a clinical model was established. Totally 9 radiomics features were included in the radiomics model. The AUCs of clinical, radiomics, and combined models for predicting SLOR after IFX treatment in CD patients were 0.691 (95% CI 0.591-0.792), 0.896 (95% CI 0.836-0.955), and 0.910 (95% CI 0.855-0.965) in the training set, and 0.722 (95% CI 0.574-0.871), 0.866 (95% CI 0.764-0.968), and 0.889 (95% CI 0.796-0.982) in the testing set. Decision curve analysis in the testing set showed higher net clinical benefits for both the radiomics model and combined model than the clinical model, and combined model had higher net clinical benefits than the radiomics model over most threshold probability intervals. Conclusions:CTE-based radiomics model can effectively predict SLOR after IFX treatment in patients with CD, and a combined model by incorporating clinical characteristics of disease duration and intestinal stenosis can further improve the predictive efficacy.

Objective To analyze the epidemiological characteristics of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2011, so as to provide insights into for echinococcosis control and surveillance. Methods The data pertaining to reported echinococcosis cases in Henan Province from 2010 to 2021 were retrieved from the National Notifiable Disease Report System, and a descriptive epidemiological analysis was performed using the software SPSS 22.0. Results A total of 150 echinococcosis cases were reported in Henan Province from 2010 to 2021, including 88 confirmed cases (58.67%) and 62 clinically diagnosed cases (41.33%), 77 cases reported by Henan Province (51.33%) and 73 cases reported by other provinces (48.67%). Echinococcosis cases were reported in each month, with 8 to 21 cases reported in each month, and the number of reported echinococcosis cases appeared no remarkable temporal changes. The echinococcosis cases were reported across 18 cities of Henan Province, with the highest number of cases reported in Zhoukou (17.33%) and Nanyang cities (17.33%) and the lowest number reported in Sanmenxia City (0.67%). The reported echinococcosis cases had a male to female ratio of 1.17:1, and the cases were found at each age group, with the the highest number of cases seen at ages of 20 to 59 years (73.33%). Farmer was the predominant occupation (63.33%), followed by housekeepers and the unemployed (12.67%). Of all reported echinococcosis cases, there were 25 local cases (16.67%) and 125 imported cases (83.33%), 144 cases reported by medical institutions (96.00%) and 6 cases reported by centers for disease control and prevention (4.00%). Conclusions Although imported echinococcosis cases were the predominant source of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2021, there were still sporadic local cases, and the emergence of local sources of infection cannot be excluded. Further expanded field surveys and surveillance of echinococcosis are required.

Objective: To evaluate the effect of different irradiation methods on the long-term prognosis of patients with clinical T_2-3N₀M₀ esophageal squamous cell carcinoma, aiming to select the optimal treatment for these patients. Methods: A total of 268 eligible patients admitted to our hospital from January 2007 to December 2012 were enrolled in this study. All patients were divided into the involved-field irradiation (IFI) and elective node irradiation (ENI) groups. The composition ratio, prognostic factors and adverse events were analyzed between two groups. Results: The median overall survival (OS) time was 35.5 months (95%CI : 30.12-40.88) and the median disease-free survival (DFS) time was 23.5 months (95%CI: 19.00-28.00). According to the multivariate analysis results, all patients were assigned into two groups at a ratio of 1 vs.1(n=86 in each group). Multivariate analysis after propensity score matching (PSM) demonstrated that irradiation method was the independent factor of OS (P=0.038), and T stage and radiotherapy were the independent factors affecting DFS (P=0.002, 0.032). The incidence of ≥grade Ⅱ adverse events did not significantly differ between two groups (P=0.819, 0.756). However, patients with combined chemotherapy experienced more adverse events. Conclusion ENI can prolong the OS and DFS of patients with clinical T_2-3N₀M₀ esophageal squamous cell carcinoma, and does not increase the incidence of severe adverse events.

Objective: To evaluate the effect of locoregional risk factors of esophageal cancer on the recurrence of gross tumor volume (GTV) in patients with N₀ esophageal squamous cell carcinoma after radical intensity-modulated radiotherapy (IMRT) and to evaluate its effect on the 10-year survival of patients. Methods: Clinical data of 374 patients with clinical N₀ esophageal squamous cell carcinoma who underwent radical IMRT in the Fourth Hospital of Hebei Medical University from 2005 to 2010 were retrospectively analyzed. Involved-field irradiation was performed in 284 patients and selective lymph node irradiation was given in 90 patients. Concurrent radiochemotherapy was conducted in 69l patients and sequential radiochemotherapy was performed in 38 patients. The survival analysis was carried out by Kaplan-Meier method. The prognosis analysis was performed by multivariate Cox’s regression model. Results: A total of 143 patients (38.2%) had recurrence in GTV. The maximum transverse diameter (GTV-D), GTV volume (GTV-V) and GTV volume/length (GTV-V/L) of GTV patients were significantly longer than those without recurrence in GTV (P=0.008, 0.043, 0.001). ROC curve analysis showed that the optimal diagnostic thresholds for GTV-D, GTV-L, GTV-V and GTV-V/L for GTV recurrence were 3.5 cm, 5.5 cm, 24.0 cm³ and 4.6 cm², respectively (P=0.000, 0.003, 0.000 and 0.000), and the ratio of recurrence within GTV in the patient group was significantly greater than that in the smaller group (P=0.000, 0.002, 0.001 and 0.000). GTV-L and GTV-V/L were the independent risk factors of recurrence in GTV (P=0.021 and 0.009). The 3-, 5-and 10-year survival rates of all patients in the whole group were 42.9%, 23.2% and 7.9%, respectively. Multivariate analysis demonstrated that age, T stage, concurrent radiochemotherapy, GTV-D and GTV-V/L were the independent risk factors of survival (P=0.027, 0.000, 0.018, 0.009 and 0.034). The main cause of death in patients with a survival time of more than 5 years was still associated with cancer. Conclusions The locoregional risk factors of esophageal cancer exert significant effect on the recurrence of GTV in patients with N₀ esophageal squamous cell carcinoma undergoing radical radiochemotherapy, which can be utilized as the predicting markers. Both GTV-D and GTV-V/L are significantly correlated the 10-year survival of patients.

Objective:To analyze the clinical prognosis of patients with cervical and upper thoracic esophageal squamous cell carcinoma treated with radical intensity-modulated radiotherapy (IMRT) with or without chemotherapy, and to explore the significance of elective lymph node irradiation (ENI).Methods:A retrospective analysis was performed on 309 patients with cervical and upper thoracic esophageal squamous cell carcinoma who underwent IMRT with or without chemotherapy in the Department of Radiology, the Fourth Hospital of Hebei Medical University. The prognostic factors were analyzed and patients receiving different irradiation methods were assigned into different group. The curative effect, toxicity and side effects were analyzed among different groups.Results:The 1-, 3-and 5-year overall survival (OS) and progression-free survival (PFS) were 76.7%, 37.4%, 19.3% and 59.7%, 27.4% and 14.4%, respectively, with median values of 26.8 and 15.5 months. Multivariate analysis showed that gender, cTNM staging and chemotherapy were the prognostic factors affecting the OS ( P=0.003, P<0.001, P=0.022), and gender, cTNM stage and radiation mode were the prognostic factors affecting the PFS ( P=0.016, P<0.001, P=0.008). After propensity score matching (PSM), the 1-, 3-, and 5-year OS and PFS were 77.2%, 39.3%, 20.0%, and 62.0%, 29.3%, and 15.4%, respectively, with median values of 27.1 and 18.2 months. Multivariate analysis showed that gender, cTNM staging and chemotherapy were the prognostic factors affecting the OS ( P=0.026, P<0.001, P=0.017); cTNM staging and irradiation mode were the prognostic factors affecting the PFS ( P<0.001, P=0.008). A subgroup analysis of chemotherapy showed that patients receiving 3-4 cycles of chemotherapy were preferred. The side effects of the patients were mainly grade 0 to 2, which could be tolerated. Conclusions:IMRT combined with or without chemotherapy is an efficacious treatment for patients with cervical and upper thoracic esophageal squamous cell carcinoma; ENI can improve the PFS of patients.

Objective To explore the effect of microRNA-613 (miR-613)/Wee1 axis on the radiosensitivity of colorectal cancer cells.Methods A total of 20 patients with radiosensitive colorectal cancer and 20 patients with radioresistance were selected from Yan'an Hospital Affiliated to Kunming Medical University from November 2016 to May 2017.Human colorectal cancer cell lines LoVo and HCT116 were selected and the radioresistant cell lines LoVo/R and HCT116/R were established for subsequent experiments.Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect the expression of miR-613 and Wee1 in colorectal cancer tissues and cell lines.The radioresistant cells were transfected by miR-613 mimic,and non-transfected cells were used as control group.The effects of miR-613 overexpression on the proliferation,invasion and cell cycle of radiation resistance of colorectal cancer cells at different radiation doses were evaluated by CCK-8 assay,Transwell assay and Western blotting,respectively.Furthermore,dual-luciferase reporter gene assay was used to verify whether Wee1 was a target gene of miR-613.si-Wee1 was transfected into radioresistant cells of colorectal cancer,or co-transfected with si-Wee1 and miR-613 inhibitor,and non-transfected cells were used as control group.The effects of miR-613/Wee1 axis on cell proliferation,invasion and cell cycle were detected by CCK-8,Transwell and Western blotting at different radiation doses.Results The expression of miR-613 was downregulated in the radiation resistance group of patients (1.54 ± 0.25 vs.2.64 ± 0.45;t =3.140,P =0.009) and radiation resistance cell lines (LoVo/R vs.LoVo:1.03 ± 0.12 vs.3.05 ± 0.15;t =8.944,P =0.006;HCT116/R vs.HCT116:1.01 ±0.11 vs.2.85 ±0.16;t =8.050,P =0.008).Overexpression of miR-613 was significantly inhibited the proliferation (LoVo/R:t6 Gy =6.018,P =0.013;HCT116/R:t6Gy =5.634,P =0.015) and invasion (LoVo/R:45.00 ± 8.95 vs.180.15 ± 6.95,t6 Gy =11.93,P =0.003;HCT116/R:49.97 ±6.21 vs.170.20 ±7.03,t6 Gy =12.82,P =0.006) of LoVo/R and HCT116/R cells and decreased the expression levels of G2-M phase cell cycle correlated proteins (CDK1 and cyclin B).Moreover,dual-luciferase reporter gene assay confirmed that Wee1 was a target of miR-613.Mechanistically,overexpression of miR-613 promoted the radiosensitivity of LoVo/R and HCT116/R cells through inhibiting cell proliferation (compared with si-Wee1 group,co-transfected with si-Wee1 and miR-613 inhibitor,and control group,LoVo/R:F8 Gy =40.742,P =0.007;HCT116/R:F8 Gy =28.958,P =0.011),invasion (LoVo/R:F8 Gy =55.413,P =0.004;HCT116/R:F8 Gy =65.634,P =0.003) and arresting cell at G2-M phase via downregulating Wee1.Conclusion miR-613/Wee1 axis plays a certain role in regulating the radiation resistance of colorectal cancer cells,overexpression of miR-613 may reverse the radiation resistance of colorectal cancer cells.
