AIM:To detect the expression levels of miR-744-5p and E3 ubiquitin protein ligase(PELI3)in conjunctival epithelial cells of perimenopausal patients with dry eye, and analyze their correlation with sex hormone level, inflammatory factor level and tear secretion function.METHODS: A total of 60 perimenopausal patients with dry eye admitted to our hospital from February 2020 to February 2022 were selected as the observation group, in addition, 60 perimenopausal subjects with no abnormal eye examination were included as a control group. The tear film break-up time(BUT), Schirmer I test(SⅠt)and corneal fluorescein staining(FL)scores of perimenopausal patients with dry eye were collected. The conjunctival epithelial cells of the two groups were obtained by impression cytology, the expression level of miR-744-5p was detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR), the PELI3 levels of conjunctival epithelial cells and serum levels of follicle stimulating hormone(FSH), estradiol(E2), luteinizing hormone(LH), interleukin-1(IL-1), interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay; correlation analysis was conducted by Pearson and Spearman methods.RESULTS: The expression level of miR-744-5p in conjunctival epithelial cells of patients in the observation group was higher than that in the control group, and the expression level of PELI3 was lower than that in the control group(all P<0.05). Compared with the control group, the expression levels of FSH, IL-1, IL-6 and TNF-α in serum of patients increased in the observation group, and the expression levels of E2 and LH in serum decreased(all P<0.05). Correlation analysis showed that miR-744-5p was negatively correlated with PELI3 in conjunctival epithelial cells of perimenopausal dry eye patients(r=-0.476, P<0.01); miR-744-5p was negatively correlated with LH, E2, BUT and SⅠt(all P<0.05), while it was positively correlated with FSH, IL-1, IL-6, TNF-α and FL scores(all P<0.05); PELI3 was negatively correlated with FSH, IL-1, IL-6, TNF-α and FL scores, while it was positively correlated with E2, BUT and SⅠt(all P<0.05).CONCLUSION: The level of miR-744-5p increased and PELI3 decreased in conjunctival epithelial cells of perimenopausal patients with dry eye. PELI3 and miR-744-5p were closely related to the sex hormones level, inflammatory factor level and the function of tear secretion in perimenopausal patients with dry eye.

Objective:To investigate the application effects of learning pyramid theory combined with constructivism in the standardized training of nurses in the department of gastroenterology.Methods:We randomly divided 104 gastroenterology nurses who received standardized training from October 2021 to October 2023 into observation group and control group, with 52 nurses in each group. The control group received conventional teaching, while the observation group received a combination of learning pyramid theory and constructivist teaching. The two groups were compared in terms of theoretical and practical scores, core competencies, self-learning abilities, and professional values scores before and after training. SPSS 23.0 was used to perform the t-test. Results:After training, the two groups showed improvements in all the tests; and the scores were all significantly higher in the observation group than in the control group: theoretical knowledge [(88.61±15.62) vs. (81.76±14.27)], skill practice [(82.91±15.17) vs. (76.40±13.82)], Competency Inventory for Registered Nurses scale score [(157.83±21.73) vs. (125.40±15.77)], self-learning ability score [(123.38±21.62) vs. (97.43±15.23)], and Nurse Professional Values scale score [(89.15±14.63) vs. (78.52±12.84)].Conclusions:The teaching model of learning pyramid theory and constructivism theory can enhance standardized training effectiveness for gastroenterology nurses.

Objective To investigate the effect of rosa roxburghii Tratt polysaccharides(RRTP)on insulin resistance(IR)in rats with gestational diabetes mellitus(GDM)by regulating adenosine monophosphate-activated protein kinase(AMPK)/peroxlsome proliferator-activated receptor-γ coactlvator-1α(PGC-1α)signaling pathway.Methods Ten pregnant rats served as normal control(NC)group,and 50 GDM rats were randomly divided into GDM group,RRTP 100 mg/kg(RRTP 100)group,RRTP 200 mg/kg(RRTP 200)group,positive drug(PD)group,RRTP 200 mg/kg+Dorsomorphin(RRTP 200+Dorsomorphin)group.The indexes of glucose and lipid metabolism,superoxide dismutase(SOD),malondialdehyde(MDA),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)and pathological changes were evaluated in each group,and Schmidt scoring shall be performed.Additionally,apoptosis and the expression of proteins related to the AMPK/PGC-1α pathway in tissues shall be detected.Results Fasting plasma glucose,fasting insulin,homeostatic model assessment-IR,total cholesterol,triglycerides,low-density lipoprotein cholesterol,MDA,IL-6,TNF-α,Schmidt score and apoptosis index were higher in GDM group than in NC group(P<0.05),while the expressions of high-density lipoprotein cholesterol,SOD,p-AMPK/AMPK,p-AMPK and PGC-1α protein were lower in GDM group than in NC group(P<0.05).The above indexes improved in RRTP 100,RRTP 200 and PD groups.In the RRTP 200+Dorsomorphin group,the ameliorative effect of RRTP on IR was reversed.Conclusions RRTP improve IR in GDM rats by activating the AMPK/PGC-1α signaling pathway.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.
