Objective:To analyze the application effect of the case-based learning (CBL), lecture-based learning (LBL) and seminar three-track stereoscopic model in the teaching of health management for chronic diseases.Methods:In this non-randomized controlled trial, a total of 70 five-year clinical medicine major undergraduate students were continuously selected as the research subjects in the Air Force Medical University during 2023-2024 year. The students enrolled the chronic disease health management course. Thirty-five cases in 2023 were assigned to the control group, while 35 cases in 2024 were assigned to the experimental group. The control group were taught by the traditional teaching method, while experimental group were taught with a combined model of CBL, LBL, and Seminar. The number of class hours for both groups were 30, with a class frequency of 2 class hours per week. The intervention period began with the first class and ended after the last class, totaling 15 weeks. The general information, medical professional courses and basic knowledge of chronic disease health management scores in the two groups were collected before intervention. The learning effect and satisfaction rate were evaluated through teaching satisfaction score, assessment assignments, practical ability score and excellent rate, autonomous learning ability score at 15 weeks after the intervention.Results:Among the 70 participants, 37 were male and 33 were female, with a mean age of (21.00±0.27) years. Before the intervention, there was no statistically significant differences in the general information, medical professional courses and basic knowledge of chronic disease health management scores between the two groups (all P>0.05). Fifteen weeks after the intervention, the experimental group had significantly higher scores in teaching content score, teaching method score, assessment assignment, final grade, practical ability scores, excellent rate of practical ability, self-management ability score, information literacy score, and learning cooperation ability score when compared to those in the control group [(93.3±6.9) vs (80.1±7.8) points, (97.1±6.3) vs (81.0±9.6) points, (91.1±7.8) vs (80.1±8.9) points, (92.9±9.4) vs (81.8±9.8) points, (91.3±7.6) vs (80.3±8.7) points, 54.3% vs 22.9%, (27.3±4.8) vs (22.8±6.8) points, (26.9±3.9) vs (20.8±4.1) points, (35.9±8.1) vs (28.9±7.1) points] (all P<0.05). Conclusion:Implementing of CBL, LBL, and Seminar teaching model in the chronic disease health management curriculum significantly enhances teaching effectiveness and improves students' overall competencies.

Objective The aim of this study was to reveal the association characteristics between cancer and depression u-sing the data from community-based multi-morbidity study in rural China(COMMON),and provide a scientific basis for early pre-vention and intervention of depression in cancer patients.Methods We collected questionnaire responses,physical examination re-cords,health insurance data,and electronic medical records from both cancer and non-cancer participants.Using propensity score matching at a 1∶4 ratio,we balanced baseline characteristics between the cancer and control groups.We then compared the preva-lence of depression between these groups,as well as across subgroups stratified by age,sex,income,and other factors.The association between cancer and depression risk was assessed using univariate and multivariate logistic regression.Finally,we conducted sensitivity analyses by restricting the regression models to participants with mild-to-severe depression.Results After matching the baseline characteristics,a total of 206 cancer patients and 824 controls were included in the study,and all baseline characteristics between the two groups.Among all individuals,women,participants under 60 years old and those from low-income families(10,000-34,999 Yuan per year),the cancer group had a higher prevalence of depression than the non-cancer group(P<0.05),no difference was found in other subgroup(P>0.05).The results of multivariate logistic regression analysis showed that cancer was an independent risk factor for depression,and the risk of depression in cancer patients was 2.38 times that of participants without cancer(95%CI:1.44-3.89,P<0.001).The analysis results of different gender,age,and family income subgroups showed that the effect of cancer on the risk of de-pression was different among subgroups(P<0.05).Conclusions Cancer is an independent risk factor for depression.Therefore,the assessment and intervention of mental health should be paid attention during the treatment of cancer patients.It is of great significance to screen for depression in cancer patients and intervene in them to improve the life quality of patients.In addition,paying attention to high-risk groups can help to implement targeted prevention and intervention and improve their mental health.

OBJECTIVE: To analyze a Chinese pedigree with Hereditary coagulation factor Ⅻ (FⅫ) deficiency duo to variants of F12 gene and explore its molecular pathogenesis. METHODS: A patient who underwent laparoscopic cystectomy at the Department of Gynecology of the First Affiliated Hospital of Wenzhou Medical University in June 2012 was selected as the study subject. Coagulation factor indexes of the proband and her family members (5 individuals from three generations) were determined. All exons, flanking sequences, 5' and 3' untranslated regions of the F12 gene of the proband and her family members were analyzed by direct sequencing. Three bioinformatics software was used to analyze the conservation, pathogenicity and protein model of the variant. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No. 2012-17). RESULTS: The activated partial thromboplastin time (APTT), FⅫ activity (FⅫ:C) and FⅫ antigen (FⅫ:Ag) of the proband was 180.0 s, 1.0% and 2.1%, respectively. DNA sequencing revealed that she has harbored compound heterozygous variants of the F12 gene, namely c.712_713insT (p.Cys238Leufs *73) in exon 8 and c.1561G>A (p.Glu521Lys) in exon 13. Her mother and younger son were heterozygous for the p.Cys238Leufs*73 variant, while her older son was heterozygous for the p.Glu521Lys variant. Bioinformatic analysis suggested that Cys238 is highly conserved and p.Cys238Leufs*73 is a pathogenic variant, which eventually resulted in a truncated protein. CONCLUSION The c.712_713insT and c.1561G>A compound heterozygous variants of the F12 gene probably underlay the decreased FⅫ level in this pedigree, among which c.712_713insT (NM_000505) was unreported previously.

ObjectiveTo explore the protective effect of polysaccharide from Inonotus obliquus （IOP） on lipopolysaccharide （LPS）-induced acute lung injury （ALI） in mice. MethodA total of 40 male C57BL/6 mice were randomly divided into normal group， model group， dexamethasone group， and high-dose and low-dose IOP groups， with eight mice in each group. The high-dose and low-dose IOP groups were administered intragastrically with IOP at 20 and 10 mg·kg^-1， respectively. The normal group and the model group were intragastrically administered with normal saline in equal volumes， and the dexamethasone group was intraperitoneally injected with dexamethasone phosphate injection of 30 mg·kg^-1 for 21 days. An ALI mouse model induced by LPS was constructed， and hematoxylin-eosin （HE） staining， immunofluorescence staining， and blood routine were used to detect pathological damage of lung tissue and blood cell content. Enzyme-linked immunosorbent assay （ELISA） and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） were used to detect the expression levels of various inflammatory factors. Changes in gut microbiota and plasma differential metabolites in mice were detected using 16S rRNA sequencing and ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry （UPLC-Q-TOF-MS）. ResultCompared with the model group， the lung tissue lesions of ALI mice were significantly improved after IOP administration， and the spleen and thymus index were dramatically increased （P<0.05， P<0.01）. The ratio of wet-to-dry weight of lung tissue was sensibly decreased （P<0.05， P<0.01）， and the number of lymphocytes was substantially increased （P<0.05， P<0.01）. The number of neutrophils was markedly decreased （P<0.01）. The expression level of interleukin-6 （IL-6）， interleukin-8 （IL-8）， interleukin-1β （IL-1β）， nuclear factor-κB（NF-κB）， and nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） decreased prominently （P<0.05， P<0.01） and the expression level of interleukin-10 （IL-10） increased memorably （P<0.01）. The 16S rRNA sequencing results show that IOP can regulate and improve intestinal microbial disorders. The UPLC-Q-TOF-MS results indicate that the treatment of ALI mice with IOP may involve pathways related to mitochondrial， sugar， and amino acid metabolism， such as nucleotide sugar metabolism， histidine metabolism， ubiquinone， and other terpenoid compound-quinone biosynthesis， as well as starch and sucrose metabolism. ConclusionThe improvement of lung tissue lesions and inflammatory response by IOP in ALI mice may be related to maintaining intestinal microbiota balance， regulating mitochondrial electron oxidation respiratory chain， as well as sugar and amino acid metabolism pathways， and affecting the production of related microbial metabolites and tricarboxylic acid cycle metabolites.

Objective:To investigate the effect of water intake on bladder filling time before embryo transfer.Methods:A total of 189 patients were collected from February to June 2023 who were to undergo embryo transfer in Guangdong Women and Children Hospital. The patients were divided into group A ( n=61), group B ( n=64) and group C ( n=64) using a random number table and they were respectively given 300 mL, 500 mL and 700 mL water to drink. Abdominal ultrasound was performed every 15 min, a total of 1-5 times, from 45 min after drinking water until the bladder filling. The bladder filling time and bladder volume were collected. Kaplan-Meier method was used to compare the difference of bladder filling time among the three groups. The multivariate Cox regression was used to analyze factors of bladder filling time. Results:The cumulative bladder filling rates of group A, group B and group C at 105 min after drinking water were 57.4% (35/61), 90.6% (58/64) and 98.4% (63/64), respectively, and the median survival time (95% CI) of bladder filling was 105.0 (89.9-120.1) min, 60.0 (55.4-64.7) min and 60.0 (55.4-64.6) min, respectively. Pairwise comparison of Kaplan-Meier analysis revealed that the bladder filling time of group A was longer than that of group B and group C ( P<0.001), and there was no statistically significant difference between group B and group C ( P>0.05). The results of age-stratification analysis showed that the bladder filling time of younger patients in group A [90.0 (75.2-104.8) min] was longer than that in group B [60.0 (55.8-64.2) min, P<0.001] and group C [60.0 (55.1-64.8) min, P<0.001], and there was no statistical significance between group B and group C ( P>0.05); the bladder filling time of older patients in group C [60.0 (59.1-70.9) min] was shorter than that in group A [105.0 (89.9-120.1) min, P<0.001] and group B [75.0 (64.3-85.7) min, P=0.027], there was no statistical significance between group A and group B ( P>0.05). Multivariate Cox regression analysis showed that taking group A as reference, the hazard ratio ( HR, 95% CI) of groups B and C were 2.71 (1.78-4.21) and 3.23 (2.10-4.96), both P<0.001. The HR (95% CI) of the elderly patients was 0.69 (0.49-0.99), P=0.044. Conclusion:Water intake and age are independent factors affecting bladder filling time in embryo transfer patients. Patients are recommended to drink 500 mL of water 75 min before embryo transfer and appropriately increase the amount of water or extend the bladder preparation time after drinking water for elderly patients.
