ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

ObjectiveTo construct a risk prediction model for frequent acute exacerbations of chronic obstructive pulmonary disease （COPD） under disease-syndrome combination， thus providing decision support for precise clinical intervention. MethodsA total of 2 029 patients with acute exacerbations of COPD admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from January 2020 to August 2024 were retrospectively included. These patients were classified into groups of frequent acute exacerbations （≥2 times/year） and infrequent acute exacerbations （<2 times/year） according to the hospitalization times per year. Risk factors were screened by LASSO regression combined with logistic regression， and a nomogram model was constructed. The model performance was assessed based on the area under the curve （AUC）， calibration curves， and decision curve analysis （DCA）. ResultsThe differences in baseline characteristics between the frequent acute exacerbations group （1 196 cases） and infrequent acute exacerbations group （833 cases） were not statistically significant. LASSO regression combined with multivariate logistic regression screened the following independent risk factors： body mass index （BMI）， hospitalization days， number of smoking years， place of residence， use of noninvasive ventilators， oxygen-demanding therapy， liver cirrhosis， use of systemic glucocorticosteroids， and traditional Chinese medicine syndrome （phlegm and stasis obstructing the lung）. The nomogram model showed good discrimination and calibration in both the training set （AUC=0.748） and validation set （AUC=0.774）. ConclusionThe risk prediction model for frequent acute exacerbations of COPD， integrating traditional Chinese medicine syndrome， constructed in this study has high accuracy. It can provide a scientific basis for early clinical identification of high-risk patients and individualized intervention.

ObjectiveTo evaluate the therapeutic effects of Huanglian Jiedutang on cerebral infarction injury in a mouse model of middle cerebral artery occlusion （MCAO） and to explore its mechanism of action on oligodendrocytes， particularly its potential in myelin repair. MethodsMultiple experimental approaches were used to evaluate cerebral ischemic injury and the effects of drug intervention. Laser speckle imaging was used to detect changes in cerebral blood flow， 2，3，5-Triphenyltetrazolium chloride （TTC） staining was used to measure infarct volume， and neurological function was scored according to the Zea-Longa criteria. Brain tissues were routinely embedded in paraffin and subjected to HE and Nissl staining to observe tissue structure and neuronal damage. Animals were divided into a sham group （n=24）， model group （n=24）， Huanglian Jiedutang group （n=24）， and Ginkgo biloba extract （GBE） group （n=18）. After 1 week of acclimatization， intragastric administration was initiated. The sham and model groups received normal saline， the Huanglian Jiedutang group was administered 1.82 g·kg^-1， and the GBE group was administered 0.432 g·kg^-1 after preparation as a 2.16 g·L^-1 solution. All groups were treated for 5 consecutive days at a dose of 0.2 mL·（10 g）^-¹·d^-¹. The MCAO model was established after the final administration on day 6. Single-cell RNA sequencing was used to analyze brain tissue cellular composition and changes in oligodendrocyte subpopulations. Distinct subpopulations were identified by Uniform manifold approximation and projection （UMAP） dimensionality reduction and unsupervised clustering， and marker gene expression was analyzed. Pathway enrichment and causal inference were further performed using IPA. Finally， real-time quantitative PCR was used to verify mRNA expression changes of myelin-related genes. ResultsCompared with the sham group， the model group showed significantly increased neurological function scores （P<0.01）， significantly impaired blood flow （P<0.01）， significantly enlarged cerebral infarct area （P<0.01）， and pathological changes including disordered cortical structural arrangement， aggravated cytoplasmic vacuolization， and increased Nissl bodies. Compared with the model group， the Huanglian Jiedutang and GBE groups showed significantly decreased neurological function scores （P<0.01）， markedly restored blood flow levels （P<0.01）， significantly reduced cerebral infarct area （P<0.01）， and improvement in cortical structural disorder， alleviation of cytoplasmic vacuolization， and a reduction in Nissl bodies. Single-cell data showed that a myelin-associated oligodendrocyte （Mye-OL） subpopulation existed among oligodendrocytes， which was closely related to myelin generation. Compared with the sham group， the number of Mye-OL cells decreased in the model group. Compared with the model group， the number of Mye-OL cells increased in the Huanglian Jiedutang group. This subpopulation promoted the expression of myelin-related genes， including MOG， MBP， and MAG， via transcription factors such as OLIG1， OLIG2， NKX2-2， and SOX10， thereby regulating myelin generation， restoring cognition， and exerting therapeutic effects on acute cerebral infarction. Compared with the sham group， the mRNA expression levels of OLIG1， OLIG2， NKX2-2， and SOX10 were significantly downregulated in the model group （P<0.01）， and the mRNA expression levels of myelin-related genes， including MOG， MBP， and MAG， were also significantly downregulated （P<0.01）. In contrast， compared with the model group， the Huanglian Jiedutang and GBE groups showed significantly upregulated mRNA expression levels of OLIG1， OLIG2， NKX2-2， and SOX10 （P<0.01）， and significantly upregulated mRNA expression levels of myelin-related genes， including MOG， MBP， and MAG （P<0.01）. ConclusionHuanglian Jiedutang exerts therapeutic effects on acute cerebral infarction by regulating the OLIG1/2-NKX2-2-SOX10 signaling pathway to promote myelin generation by Mye-OL cells.

Objective Microcystin-leucine-arginine(MC-LR)exposure induces lipid metabolism disorders in the liver.Secreted frizzled-related protein 5(SFRP5)is a natural antagonist of winglesstype MMTV integration site family,member 5A(Wnt5a)and an anti-inflammatory adipocytokine.In this study,we aimed to investigate whether MC-LR can induce lipid metabolism disorders in hepatocytes and whether SFRP5,which has anti-inflammatory effects,can alleviate the effects of hepatic lipid metabolism by inhibiting the Wnt5a/Jun N-terminal kinase(JNK)pathway. Methods We exposed mice to MC-LR in vivo to induce liver lipid metabolism disorders.Subsequently,mouse hepatocytes that overexpressed SFRP5 or did not express SFRP5 were exposed to MC-LR,and the effects of SFRP5 overexpression on inflammation and Wnt5a/JNK activation by MC-LR were observed. Results MC-LR exposure induced liver lipid metabolism disorders in mice and significantly decreased SFRP5 mRNA and protein levels in a concentration-dependent manner.SFRP5 overexpression in AML12 cells suppressed MC-LR-induced inflammation.Overexpression of SFRP5 also inhibited Wnt5a and phosphorylation of JNK. Conclusion MC-LR can induce lipid metabolism disorders in mice,and SFRP5 can attenuate lipid metabolism disorders in the mouse liver by inhibiting Wnt5a/JNK signaling.

Objective:To explore the effect of group education intervention strategy based on harmonious nursing theory on understanding and application of pelvic floor knowledge and exercise skills in first gestation women, so as to promote the early recovery of pelvic floor function in postpartum women.Methods:This study was a quasi-experimental study. A total of 80 first gestation women in the pregnant women′s school of the First Hospital of Shanxi Medical University were selected as the research objects, 40 women from April to May 2023 were involved in the control group and 40 women from June to July 2023 were involved in the intervention group. The control group was given routine health education, while the intervention group was given group educational nursing intervention based on harmonious nursing theory. The Primary Prevention of Female Pelvic Floor Dysfunction-self-care Ability Scale was used to evaluate and compare the primary prevention self-care ability of pelvic floor dysfunction among pregnancy 1-4 weeks between the two groups before and after pregnancy intervention. Pelvic floor muscle strength was measured and pelvic floor function exercise compliance was evaluated during outpatient follow-up at 42-49 days postpartum (hereinafter referred to as postpartum 42 days) to evaluate and compare the rehabilitation effect of pelvic floor skills exercise between the two groups at 42 days postpartum.Results:Finally, the control group was (29.97 ± 3.68) years old involved 38 cases, and the intervention group was (29.79 ± 3.66) years old involved 38 cases. There was no significant difference in self-care ability score of primary prevention of pelvic floor dysfunction between the two groups before intervention ( P>0.05). After pregnancy intervention, the scores of self-care knowledge, self-care responsibility, self-care skills, self-regulation and total score of the intervention group were (58.13 ± 6.46), (11.73 ± 1.18), (10.16 ± 0.86), (29.21 ± 2.74) and (109.21 ± 8.92) points, respectively, which were higher than the control group (47.76 ± 4.25), (11.05 ± 1.09), (8.82 ± 1.78), (27.34 ± 2.18), (94.97 ± 6.46) points, and the differences between the two groups were statistically significant ( t values were - 8.26 - - 2.63, all P<0.05). In the intervention group, the maximum value of the fast muscle stage and the mean value of the slow muscle stage of the comparison of pelvic floor muscle strength between the two groups 42 days after delivery were 48.25(44.75, 53.45)μV and 31.00 (27.33, 34.23) μV, respectively, which were higher than the control group 36.80 (32.25, 44.28) μV and 22.40 (19.28, 25.88) μV, the differences between the two groups were statistically significant ( Z = - 4.98, - 5.37, both P<0.01). There was no significant difference in the average value of the pre-resting stage and the average value of the post-resting stage between the two groups ( P>0.05). Comparison of pelvic floor functional exercise compliance between the two groups showed that in the intervention group, the proportion of good compliance was 73.7% (28/38), and the proportion of general compliance was 26.3% (10/38), while in the control group, the proportion of general compliance was 86.8% (33/38) and the proportion of good compliance was 7.9% (3/38). The difference between the two groups was statistically significant ( χ2 = 34.46, P<0.01). Conclusions:Application of the theory of harmonious nursing group educational nursing intervention was carried out on the first gestation women, can effectively improve the first gestation women during pregnancy pelvic floor functional exercise primary prevention self-care ability level, strengthen puerperal women pelvic floor muscle, improve the puerperal pelvic floor functional exercise adherence, coordination and optimization of the first gestation women early for pelvic floor functional rehabilitation nursing process.

Epilepsy patients are prone to obesity and metabolic syndrome(MetS),which is a higher risk than the general population.Nonalcoholic fatty liver disease(NAFLD)is a manifestation of a metabolic syndrome,characterized by hepatic steatosis,which can be exacerbated to some extent in patients with epilepsy.Sodium valproate(VPA),a commonly used clinical antiepileptic drug,leads to triglyceride accumulation in liver cells and induces a risk of NAFLD.In adults with epilepsy combined with NAFLD,treatment with VPA can make the liver,which is already affected by steatosis,more sensitive to VPA-induced liver injury and affect VPA drug metabolism.Both VPA and NAFLD induce hepatic steatosis,and can exacerbate each other's induced hepatic steatosis synergistically during epilepsy treatment.In this paper,we reviewed the progress of clinical studies on the use of VPA in adult patients with epilepsy combined with NAFLD to provide references for effective treatment and future studies of VPA.

ObjectiveTo investigate the distribution and trend of rehabilitation personnel of China Disabled Persons' Federation (CDPF) system and the people with disabilities (PWDs) using geographical gravity model. MethodsBased on ArcGIS and statistical data, the distribution of geographical center of gravity of the rehabilitation personnel of the CDPF system from 2011 to 2021 was analyzed. According to the economic development, the areas were divided into three regions, and the eastern region included eleven provincial units, the central region includes eight provincial units, and the western region included twelve provincial units. ResultsCompared with 2011, rehabilitation staffs per thousand PWDs increased at 107.5% in 2021, 81.1%, 114.2% and 174.1% for the eastern, central, and western regions, respectively; professional staffs increased at 190.5%, 148.8%, 284.6% and 280.6% for the eastern, central, and western regions, respectively; managerial staff increased at 80.0%, 46.8%, 554.3% and 128.1% for the eastern, central, and western regions, respectively. Compared with 2011, the geographical center of gravity of the rehabilitation personnel moved about 330.9 km in 2021, while the geographical center of gravity of the PWDs moved about 169.64 km. ConclusionThe rehabilitation personnel in the CDPF system is the most in the eastern region and least in the western region. The tracks of the geographical center of gravity of the three kind of rehabilitation personnel in the CDPF system are relatively consistent. The rehabilitation personnel in the eastern region are more concentrated than those in the western region, and the density of the PWDs is more westward than that of the rehabilitation personnel, and coordination is not a perfect match yet. It is necessary to strengthen the rehabilitation personnel allocation in the western region, to balance distribution of human resources for rehabilitation of PWDs among regions.
