Objective To investigate the impact of scenario class teaching on language expression,communication skills,and final exam performance of non-clinical majors students in the course of Medical Parasitology.Method Undergraduate students of non-clinical medical programs from Kunming Medical University in 2022 were selected as the subjects and randomly divided into a scenario class group and a non-scenario class group.Questionnaires were administered to compare the two groups regarding their interest in the laboratory classes,enjoyment levels,and knowledge retention.Additionally,the final exam scores of the two groups were compared.Results Students in the scenario class group showed significantly higher interest(82.6%)and enjoyment levels(88.3%)for laboratory classes compared to the non-scenario class group(73.0%and 60.1%,respectively,P<0.05).Students in the scenario class group believed that situational teaching enhanced their self-learning ability(82.06%),interest in learning(83.2%),willingness to express themselves(83.2%),confidence in expression(81.8%),and communication skills(87.9%).Additionally,It effectively facilitated their understanding of the occurrence and development of parasitic diseases(85.9%)and familiarity with the diagnosis and treatment process(86.8%),thereby cultivating clinical thinking.In terms of final exam scores,the scenario class group had a higher average score(22.80±0.18)than the non-situational classroom group(21.47±0.17,P<0.05).Conclusion Sc-enario class teaching in Medical Parasitology can effectively improve students'self-learning ability,language expression,and communication skills,cultivate clinical thinking,and enhance academic performance,demonstrating significant teaching advantages.

Objective: To explore the clinical manifestations and treatment plans of chronic recurrent parotitis (CRP), and to provide a reference for the clinical diagnosis and treatment of CRP. Methods: Approval was obtained from the hospital’s Medical Ethics Committee, and a retrospective analysis and summary of the clinical features, imaging characteristics, diagnosis, and treatment of 41 CRP patients with complete data were performed. Results: Among the 41 patients with CRP, 14 were male and 27 were female, with a male-to-female ratio of approximately 1:2 (14/27). The age at first-time onset ranged from 3 to 23 years, with a median age of 6 years, and there were 38 patients (92.7%, 38/41) with the first onset age of under 18 years old. The age of the first visit to our hospital ranged from 4 to 72 years old, with an average age of (41.0 ± 17.3) years; the disease duration was 0.5 to 66 years, with an average of 35.0 ± 16.1 years. Twenty-five cases had bilateral parotid gland involvement (61.0%, 25/41). The clinical manifestations of CRP are repeated swelling of one or both parotid glands, along with discomfort, and this may be accompanied by mild edema or skin flushing and pus or jelly-like secretions at the duct openings. The typical manifestations of parotid angiography are: the dominant duct and branch ducts of the parotid gland do not have specific dilation or narrowing, and the peripheral ducts show characteristic “punctate, spherical, or cavitary” dilation and delayed emptying. Of the cases, 34 had abnormal enlargement of the main duct orifice (82.9%, 34/41), and 37 presented with abnormal anterior displacement of the accessory glands (90.2%, 37/41). The treatment plan of “antibiotic perfusion + aspiration and removal of obstruction (or aspiration after obstruction dissolution)+ postprandia massage along the direction of the parotid duct (from posterior to anterior) with multiple courses for consolidation”achieved favorable outcomes. The mean follow-up period of this group was(71.1+21.9)months, and no recurrence was observed during the follow-up period. Conclusion CRP is more prevalent in young females and frequently presents with bilateral involvement. Congenital anatomical defects, such as abnormal enlargement of the main duct orifice and abnormal anterior displacement of the accessory glands, are important predisposing factors. The multi-course comprehensive therapy centered on antibiotic infusion, removal and dissolution of obstructions, and post-prandial massage along the direction of the parotid duct has significant therapeutic effects and deserves clinical application.

Objective To discusse the application effects of the informatization of the review center and the homogeneity of pharmacists on the rationality of emergency department prescriptions.Methods Based on the system rules of the rational drug use management system and manually set custom rules,the changes in pharmacist's review quality,efficiency homogeneity,and prescription rationality were compared before(February 2023 to July 2023)and after(August 2023 to January 2024)the construction of the review center,according to the informatization and process standardization management.Results After the establishment of the review center,analysis of variance showed that the approval rate of pharmacist's review significantly increased compared to before the establishment of the review center(P＜0.05),while the average time consumption increased significantly(P＜0.01).The average review time,average approval time,and average review return time have been extended from(4.50±0.58),(4.50±0.58),and(4.75±0.96)s to(11.67±1.03),(8.50±0.55)and(13.17±0.98)s,respectively.The trend chi-square test showed that the irrationality rate of emergency department prescriptions decreased monthly from 6.27％in August 2023 to 0.93％in January 2024(P＜0.01).Correlation analysis between the number of intervention system rules since the establishment of the review center and the irrationality rate of emergency department prescriptions revealed a significant correlation(P=0.004 4).Conclusions By utilizing the platform of the review center,establishing dedicated review pharmacists and an information pharmacist team,and implementing informatization and standardized management processes,it can contribute to improving the quality and efficiency of prescription review,increasing the qualification rate of prescriptions,ensuring rational drug use,and enhancing the management level and medical quality of hospitals.

Objective To explore the correlations of serum vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) with grading of myelofibrosis (MF) in patients with myeloproliferative neoplasms (MPN). Methods Ninety patients with Philadelphia chromosome negative (Ph-)MPN were selected as MPN group. According to the grading criteria for myelofibrosis by the World Health Organization (WHO) in 2016, MPN patients were divided into pre-fibrosis or early fibrosis group with 54 cases and significant fibrosis group with 36 cases; another 50 healthy volunteers were selected as the control group. Levels of serum VEGF, MMP-9 and TIMP-1 were detected by enzyme-linked immunosorbent assay, and the ratio of TIMP-1 to MMP-9 (TIMP-1/MMP-9) was calculated. Spearman rank correlation test was used to analyze the correlations of VEGF, MMP-9, TIMP-1 and TIMP-1/MMP-9 with MF grading. Receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of each indicator alone or their combination for diagnosing MPN or distinguishing MF grading. Results Compared with the control group, the serum levels of VEGF, MMP-9 and TIMP-1 in the MPN group increased significantly (P < 0.05). Values of area under the curve (AUC) of VEGF, MMP-9, TIMP-1 and TIMP-1/MMP-9 for diagnosing MPN were 0, 834, 0.745, 0.923 and 0.618 respectively; the AUC of the combined diagnosis of MPN by VEGF, MMP-9 and TIMP-1 was 0.960; when the optimal cut-off value was 0.627, the sensitivity was 85.56%, and the specificity was 92.00%. Compared with the pre-fibrosis or early fibrosis group, the serum levels of VEGF, TIMP-1 and TIMP-1/MMP-9 in the significant fibrosis group increased significantly (P < 0.05). Spearman correlation analysis showed that VEGF (r=0.378, P=0.001), TIMP-1 (r=0.512, P < 0.001) and TIMP-1/MMP-9 (r=0.353, P=0.001) were positively correlated with the MF grading of MPN patients (P < 0.05). ROC curve analysis showed that the values of AUC of VEGF, MMP-9, TIMP-1 and TIMP-1/MMP-9 for distinguishing patients with pre-fibrosis or early fibrosis from those with significant fibrosis were 0.723, 0.523, 0.802 and 0.708 respectively; the AUC of the combined detection of VEGF, TIMP-1 and TIMP-1/MMP-9 for distinguishing patients with pre-fibrosis or early fibrosis from those with significant fibrosis was 0.838; when the optimal cut-off value was 0.530, the sensitivity was 72.22%, and the specificity was 85.19%. Conclusion Serum VEGF, TIMP-1 and TIMP-1/MMP-9 can reflect the MF progression of MPN patients, and the combined detection of these indicators can predict the MF degree of MPN patients.

Objective This study investigated the epidemic characteristics and spatio-temporal dynamics of hemorrhagic fever with renal syndrome (HFRS) in Qingdao City,China. Methods Information was collected on HFRS cases in Qingdao City from 2010 to 2022. Descriptive epidemiologic,seasonal decomposition,spatial autocorrelation,and spatio-temporal cluster analyses were performed. Results A total of 2,220 patients with HFRS were reported over the study period,with an average annual incidence of 1.89/100,000 and a case fatality rate of 2.52％. The male:female ratio was 2.8:1. 75.3％ of patients were aged between 16 and 60 years old,75.3％ of patients were farmers,and 11.6％ had both "three red" and "three pain" symptoms. The HFRS epidemic showed two-peak seasonality:the primary fall-winter peak and the minor spring peak. The HFRS epidemic presented highly spatially heterogeneous,street/township-level hot spots that were mostly distributed in Huangdao,Pingdu,and Jiaozhou. The spatio-temporal cluster analysis revealed three cluster areas in Qingdao City that were located in the south of Huangdao District during the fall-winter peak. Conclusion The distribution of HFRS in Qingdao exhibited periodic,seasonal,and regional characteristics,with high spatial clustering heterogeneity. The typical symptoms of "three red" and"three pain" in patients with HFRS were not obvious.

Objective:To investigate serum vitamin A and vitamin D status in children aged 2-<7 years in 20 cities in China.Methods:A cross-sectional study was conducted. A total of 2 924 healthy children aged 2-<7 years were recruited from September 2018 to September 2019 from 20 cities in China, categorized by age groups of 2-<3 years, 3-<5 years, and 5-<7 years. The demographic and economic characteristics and health-related information of the enrolled children were investigated. Body weight and height were measured by professional staff members. The serum vitamin A and vitamin D levels were detected by high-performance liquid chromatography-tandem mass spectrometry. Chi-square test and Logistic regression were applied to analyze the association between vitamin A and vitamin D deficiency and insufficiency as well as their underlying impact factors.Results:The age of the 2 924 enrolled children was 4.33 (3.42, 5.17) years. There were 1 726 males (59.03%) and 1 198 females (40.97%). The prevalences of vitamin A and vitamin D deficiency in enrolled children were 2.19% (64/2 924) and 3.52% (103/2 924), respectively, and the insufficiency rates were 29.27% (856/2 924) and 22.20% (649/2 924), respectively. Children with both vitamin A and vitamin D deficiencies or insufficiencies were found in 10.50% (307/2 924) of cases. Both vitamin A ( χ2=7.91 and 8.06, both P=0.005) and vitamin D ( χ2=71.35 and 115.10, both P<0.001) insufficiency rates were higher in children aged 3-<5 and 5-<7 years than those in children aged 2-<3 years. Vitamin A and vitamin D supplementation in the last 3 months was a protective factor for vitamin A and D deficiency and insufficiency, respectively ( OR=0.68 and 0.22, 95% CI 0.49-0.95 and 0.13-0.40, both P<0.05). The rates of vitamin A and D insufficiency was higher in children with annual household incomes <60 000 RMB than in those with annual household incomes ≥60 000 RMB ( χ2=34.11 and 10.43, both P<0.01). Northwest and Southwest had the highest rates of vitamin A and vitamin D insufficiency in children aged 2-<7 yeas, respectively ( χ2=93.22 and 202.54, both P<0.001). Conclusions:Among 20 cities in China, children aged 2-<7 years experience high rates of vitamin A and vitamin D insufficiency, which are affected by age, family economic level, vitamin A and vitamin D supplementation, and regional economic level. The current results suggest that high level of attention should be paid to vitamin A and vitamin D nutritional status of preschool children.

Objective:To investigate the clinical characteristics, diagnosis, treatment, and prognosis of primary thyroid lymphoma (PTL) .Methods:A retrospective analysis was conducted on the clinical and pathological data of 34 newly diagnosed PTL patients admitted to Beijing Tongren Hospital from September 2010 to February 2023. The Kaplan-Meier survival curve and Log-rank test were used for survival analysis, and the Cox regression model was applied for univariate analysis of prognostic factors.Results:All 34 PTL patients presented with cervical mass as the initial clinical manifestation. There were 9 males and 25 females. The pathological diagnosis was diffuse large B-cell lymphoma (DLBCL) in 29 patients and mucosa-associated lymphoid tissue (MALT) lymphoma in 5 patients. Among the DLBCL patients, 6 had B symptoms, 17 had an Eastern Cooperative Oncology Group (ECOG) score of ≥2, the Ann Arbor staging was stage Ⅰ-Ⅱ in 21 cases and stage Ⅲ-Ⅳ in 8 cases, the tumor diameter was ≥10 cm in 4 cases, and 14 had concurrent Hashimoto thyroiditis; 27 cases received chemotherapy, with 21 cases achieving complete remission (CR), 2 cases partial remission (PR), and 6 cases of disease progression; the 5-year progression-free survival and overall survival rates were 78.9% and 77.4%, respectively; univariate survival analysis showed that B symptoms, tumor diameter ≥10 cm, and Ann Arbor stage Ⅲ-Ⅳ were significant factors affecting patient prognosis ( P<0.05). MALT lymphoma patients were all in stages Ⅰ-Ⅱ, had an ECOG score of 0-1, and were without B symptoms. All patients underwent surgical resection, with 4 cases achieving CR and 1 case PR. Conclusion:PTL is more common in females with concurrent Hashimoto thyroiditis, with the majority of pathological types being B-cell lymphoma. The main treatment is chemotherapy, supplemented by radiotherapy and surgery, and the prognosis is relatively favorable.
