Objective:To examine the satisfaction and teaching effectiveness of Health Statistics among students majoring in Public Utility Administration,and to provide valuable insights for optimizing current teaching practices and enhancing teaching effectiveness.Methods:A survey questionnaire,specifically designed for this study,was administered to 56 students of grade 2021 majoring in Public Utility Administration in our school.The questionnaire covered topics such as the difficulty of teaching content,learning satisfaction,and the Student Evaluation of Educational Quality(SEEQ)scale.Results:Non-parametric testing was considered the most difficult knowledge point,and male students found statistical inference of quantitative data was the most challenging,while female students found non-parametric testing was the most difficult.In terms of satisfaction,the highest score was obtained for pre-class review,while the lowest score was given to improving learning interest in Rain Classroom.The overall score for teaching effectiveness,as measured by SEEQ,was good across seven dimensions.Teaching enthusiasm received the highest score(4.40±0.43),while homework volume received the lowest score(3.23±0.37).With the exception of homework grading,satisfaction was positively correlated with most dimensions of teaching effectiveness evaluation.Conclusions:Despite perceiving the course as generally difficult,students expressed high satisfaction and overall positive evaluation of teaching effectiveness.Therefore,it is recommended to actively explore new teaching reforms to cultivate well-rounded applied talents for public utilities.

Objective To analyze the clinical manifestations of delayed serological transfusion reactions(DSTR)after platelet transfusion in tumor patients,and to explore the transfusion strategy.Methods Clinical data and laboratory test re-sults of patients with positive antibody screening were analyzed after platelet transfusion in our hospital from January 1,2015 to June 30,2023,and the incidence rate,clinical characteristics and transfusion strategy of patients with DSTR were ana-lyzed.Results A total of 2 553 patients with 6 057 platelet transfusions were reviewed.Eight patients developed DSTR and received a total of 21 therapeutic amounts of platelets,and 5 patients were subsequently transfused with red blood cells.Rh system antibodies were detected in 7 cases(4 anti-E,1 anti-c/E,1 anti-C and 1 anti-c)and Kell system antibodies in 1 case.Conclusion Tumor patients may also develop DSTR after platelet transfusion.It is necessary to pay close attention to the antibody situation and perform matched transfusion when transfusing blood again.

Objective To explore the effect of urine mixing degree on 24-hour urinary total protein(24 h UTP)in patients with chronic kidney disease(CKD).Methods From October 1,2023 to December 31,2023,30 hospitalized patients who needed to complete 24 h UTP testing in Zhongshan Hospital,Fudan University were selected.A 5 L unified container was used to collect urine for 24 hours.After collection and one hour's standing,the urine sample was divided into upper,middle,and lower equal parts according to volume,which was defined as direct-sampling group.Then,the urine samples were fully mixed with a magnetic stirrer and sampled again according to the above-mentioned three-equal sampling method,which was defined as mixed-sampling group.The generalized estimating equation was used to compare the urinary protein concentration before and after mixing and at different sampling location.Results The results of generalized estimating equation showed that after controlling the variable"sampling position",there was no significant difference in urinary protein concentration between the direct-sampling group and the mixed-sampling group.After controlling the variable"mixing method",there was still no significant difference in urinary protein concentration at different sampling positions.After adjusting the covariates such as age,gender,and estimated glomerular filtration rate(eGFR),the results were consistent.Conclusions With standard protocol,the entire 24-hour urine sample is a relatively even-distributed solution.After the total urine collection is completed,the temporary sample can be directly extracted from any level of the original urine within 1 hour,and the urine protein concentration of the sample multiplied by the urine volume can reflect the 24 h UTR.

Colorectal cancer is the most common malignant tumor of digestive tract, and BRAF V600E mutations occur in approximately 10% of patients with metastatic colorectal cancer (mCRC). Cancer patients harboring this mutation have a unique molecular profile and clinical phenotype; they show poor response to systemic chemotherapy, insensitivity to single BRAF inhibitor, and short survival rate. It is important to develop new therapeutic agents and clinical strategies to improve the prognosis of these patients. This review mainly introduces treatment methods for BRAF V600E-mutated mCRC and rationally derived combinations of targeted agents and immunotherapy.

Objective:To investigate the diagnostic and prognostic value of 68Ga-fibroblast activation protein inhibitor (FAPI) PET for hepatobiliary malignancies. Methods:From July 2020 to February 2023, 33 patients (23 males, 10 females; age (55.4±13.5) years) with suspected or confirmed liver or biliary tract malignancies who underwent 68Ga-FAPI PET in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. PET images were evaluated by 3 experienced nuclear medicine physicians, and the results of biopsy or postoperative pathology, clinical and imaging follow-up were used as the gold standard. One-way analysis of variance and least significant difference t test were used to compare the differences among groups. Survival analysis was performed using Kaplan-Meier curves and the log-rank test. Results:Of 33 patients, 14 performed PET for initial diagnosis and staging, and 19 for restaging. There were 14 patients with hepatocellular carcinoma (HCC), 13 patients with cholangiocarcinoma (CCA), and 6 patients with gallbladder carcinoma (GBC). The primary tumor of HCC, CCA and GBC all showed significant 68Ga-FAPI uptake, with no statistically significant difference in SUV max among groups ( F=1.58, P=0.250). The sensitivities of 68Ga-FAPI PET for initial diagnosis and restaging of hepatobiliary malignancies were 14/14 and 15/15, respectively. Compared with conventional imaging, 68Ga-FAPI PET changed the diagnosis and staging in 29.2%(7/24) patients. The treatment strategy was changed in 30.3%(10/33) patients with malignant tumors due to 68Ga-FAPI PET findings. Follow-up showed 22 cases survived and 11 cases died, with the overall survival of 355.56(80.00, 516.97) d, and 1- and 2-year survival rates were 68.2% and 57.9%, respectively. Semi-quantitative 68Ga-FAPI PET parameters such as SUV max, target-liver ratio (TLR), and target-blood ratio (TBR) had no significant prognostic value, but the prognosis of the group without distant metastases diagnosed by 68Ga-FAPI PET was significantly better than that of the group with distant metastasis ( P=0.032). Conclusion:68Ga-FAPI PET has high sensitivity for the diagnosis of hepatobiliary malignancies, which can help guide treatment decisions and prognosis evaluation.

Objective:To study whether Bayesian penalized likelihood (BPL) and its optimized reconstruction algorithm can improve the reconstructed image quality of low count total-body PET.Methods:Eight patients (5 males, 3 females, age (67.2±6.3) years) who underwent hybrid 18F-FDG PET/MR total-body scans at Department of Nuclear Medicine in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were collected retrospectively from January to June in 2023. Total-body PET/MR images of them were included and list-mode data were reconstructed with four methods, namely 25% counts conventional reconstruction (group 1), 100% counts conventional reconstruction (group 2), 25% counts BPL reconstruction (group 3), and 25% counts optimized BPL reconstruction (group 4). At last, 32 total-body PET images were obtained. SUV max and SUV mean in different ROIs and tumor metabolic volume (MTV) were measured. Total lesion glycolysis (TLG) and parameters of image quality including the ratio of lesion to background (L/B) and image signal-to-noise ratio (SNR) were calculated. Then the differences in all the parameters among the four groups were analyzed by repeated measures analysis of variance and Friedman test. Quantitative differences between BPL reconstruction and optimized BPL with the 100% counts conventional reconstruction were compared respectively by using the Bland-Altman (BA) plot. Results:For the inter-group comparison, except for SUV mean in the muscle ( F=0.38, P=0.767), SUV max and SUV mean in other ROIs were statistically different ( F values: 8.15-36.08, χ2=18.15, all P<0.01), as well as MTV and L/B ( χ2 values: 10.65, 13.35, P values: 0.014, 0.004), but not for TLG ( χ2=4.95, P=0.175) or SNR ( F=2.64, P=0.076). For the pairwise comparison, the differences between group 2 and group 3 were the most significant (all P<0.05). Compared with group 2, there were no significant differences for SUV max and SUV mean of the cerebellar cortex and lesions in group 4 (all P>0.05), as well as MTV and L/B (both P>0.05). In addition, compared with group 1, SUV max of liver and muscle in group 2 were decreased (both P<0.05), while there were no significant differences in group 4 (all P>0.05). BA plots showed that the differences of SUV, MTV, and TLG between group 4 and group 2 were smaller obviously than those between group 3 and group 2. Conclusion:BPL reconstruction can improve low focus detection sensitivity induced by low counts, but it will cause significant changes for PET quantification, which can be solved by optimized BPL reconstruction.

Objective:To evaluate the accuracy of bedside lung ultrasound in predicting postoperative pulmonary complications (PPCs) in the patients undergoing radical resection of gastrointestinal cancer.Methods:One hundred and eight patients of both sexes, aged >18 yr, undergoing elective radical resection of gastrointestinal cancer with general anesthesia, were enrolled in the study. Lung ultrasound was performed before surgery (T 1) and at 2, 4 and 7 days after surgery (T 2-4). Lung ultrasound score (LUS) and B-line score were recorded. Serum procalcitonin (PCT) concentrations and blood routine were recorded, and systemic immune-inflammatory index (SII) was calculated. All the patients underwent chest CT examination before surgery and 7 days after surgery. The results of chest CT and clinical diagnosis were used as the gold standard for PPCs. The occurrence of PPCs within 7 days after surgery was recorded. The patients were divided into PPCs group and non-PPCs group according to the development of PPCs. Spearman′s correlation analysis was used to analyze the correlation of B-line score and LUS with PPCs, PCT and SII. The receiver operating curve was used to evaluate the accuracy of B-line score and LUB in predicting PPCs. Results:One hundred and three patients were finally enrolled in the study, including 45 patients in PPCs group and 58 patients in non-PPCs group, and the incidence of PPCs was 43.7%. Both B-line score and LUS were positively correlated with PPCs at T 1 ( P<0.001), and B-line score and LUS were positively correlated with PCT and SII at T 2-4 ( P<0.001). The AUC (95% confidence interval) of B-line score and LUB in predicting PPCs were 0.926 (0.879-0.972) and 0.909 (0.852-0.965), respectively ( P<0.001), the best cut-off values of B-line score and LUB in predicting PPCs were set at 25.5 and 11.5 respectively, and the sensitivity and specificity of B-line score were 0.80 and 0.88 respectively, and the sensitivity and specificity of LUB were 0.78 and 0.93 respectively. Conclusions:Bedside pulmonary ultrasonography (B-line score and LUS) can accurately predict the occurrence of PPCs in the patients undergoing radical resection of gastrointestinal cancer and dynamically evaluate the condition of PPCs, and B-line score >25.5 and LUS score >11.5 indicate a high risk of PPCs.

【Objective】 To evaluate the detection and distribution characteristics of anti-P1 in tumor patients, so as to aid in blood screening and transfusion safety. 【Methods】 The clinical data of 112 658 tumor patients who underwent blood preparation and transfusion in our hospital from January 2014 to December 2021 were retrospectively analyzed, and column agglutination technique was used to perform transfusion compatibility test. 【Results】 A total of 1 079 (0.96%, 1 079/112 658) cases were detected with unexpected antibodies, of which 71 (6.58%, 71/1 079) were identified as anti-P1. In anti-P1 cases, 59.15% (42/71) were males; 60.56% had no pregnancy history (P<0.01); 29.58% (21/71), 52.11%(37/71), 12.68%(9/71) and 5.63%(4/71) of anti-P1 patients were with type A, B, O and AB, respectively. 57 cases of anti-P1 patients (80.28%) had difficulty in ABO blood group identification. The incidence of interfering in patients with type B was higher than that of other blood types (P<0.05), as the frequency of w+ in reverse blood typing was higher than other reactive patterns (P<0.05). The incidence of gastric tumor and brain space-occupying lesion in patients with anti-P1 was higher than that in patients with other alloantibodies, while the incidence of gynecological tumors was lower (P<0.05). 【Conclusion】 Anti-P1 affects the ABO blood group identification of tumor patients, and most of them had difficulty in ABO blood group identification. Compared with patients with other alloantibodies, patients with anti-P1 are more likely to be male and suffer from gastric and brain tumors, but less likely from gynecological tumors.

OBJECTIVE: To evaluate the regulatory effect of berberine on autophagy and apoptosis balance of fibroblast-like synoviocytes (FLSs) from patients with in rheumatoid arthritis (RA) and explore the mechanism. METHODS: The inhibitory effect of 10, 20, 30, 40, 50, 60, 70, and 80 μmol/L berberine on RA-FLS proliferation was assessed using CCK-8 method. Annexin V/PI and JC-1 immunofluorescence staining was used to analyze the effect of berberine (30 μmol/L) on apoptosis of 25 ng/mL TNF-α- induced RA-FLSs, and Western blotting was performed to detect the changes in the expression levels of autophagy- and apoptosis-related proteins. The cells were further treated with the autophagy inducer RAPA and the autophagy inhibitor chloroquine to observe the changes in autophagic flow by laser confocal detection of mCherry-EGFP-LC3B. RA-FLSs were treated with the reactive oxygen species (ROS) mimic H₂O₂ or the ROS inhibitor NAC, and the effects of berberine on ROS, mTOR and p-mTOR levels were observed. RESULTS: The results of CCK-8 assay showed that berberine significantly inhibited the proliferation of RA-FLSs in a time- and concentration-dependent manner. Flow cytometry and JC-1 staining showed that berberine (30 μmol/L) significantly increased apoptosis rate (P < 0.01) and reduced the mitochondrial membrane potential of RA-FLSs (P < 0.05). Berberine treatment obviously decreased the ratios of Bcl-2/Bax (P < 0.05) and LC3B-II/I (P < 0.01) and increased the expression of p62 protein in the cells (P < 0.05). Detection of mCherry-EGFP-LC3B autophagy flow revealed obvious autophagy flow block in berberine-treated RA-FLSs. Berberine significantly reduced the level of ROS in TNF-α-induced RA-FLSs and upregulated the expression level of autophagy-related protein p-mTOR (P < 0.01); this effect was regulated by ROS level, and the combined use of RAPA significantly reduced the pro-apoptotic effect of berberine in RA-FLSs (P < 0.01). CONCLUSION Berberine can inhibit autophagy and promote apoptosis of RA-FLSs by regulating the ROS-mTOR pathway.

Objective:To determine the level of epilepsy knowledge of caregivers for children with epilepsy and analyze its influencing factors, and investigate caregivers' educational needs and their acceptance for remote education, in order to provide reference for clinical telenursing education.Methods:From March to September 2022, 221 caregivers of epileptic children in the outpatient department and ward of neurology department of Xuzhou Children's Hospital were recruited by convenient sampling method for cross-sectional investigation. The status of caregivers' knowledge and educational needs were investigated by the general information questionnaire, epilepsy knowledge questionnaire, epilepsy knowledge needs questionnaire and telenursing acceptance questionnaire, and the influencing factors of knowledge level were analyzed by multiple linear regression.Results:The average score of epilepsy knowledge of caregivers was (15.68 ± 6.43) points. The course of disease, taking medicine on time, education background and monthly income of caregivers were the influencing factors of caregivers' knowledge level, and the difference was statistically significant ( P <0.05). 94.12% (208/221)- 96.38% (213/221) of the caregivers had high educational needs, and they had the highest demand for safety guidance during seizures. Caregivers' acceptance of remote education was moderate, ranging from 34.39% (76/221) to 71.95% (159/221). Conclusions:Caregivers' epilepsy knowledge needs to be improved. Medical institutions should formulate education plans according to the different characteristics of caregivers. Caregivers have a high demand for nursing knowledge, and medical staff should increase health education. Before giving health education based on remote nursing platform, we should fully understand the attitude of caregivers to the platform, so that they can master disease knowledge, strengthen their disease management ability, and improve the quality of life of children.
