Objective: To explore and validate the potential targets of Paeoniae Radix Alba (P. Radix, Bai Shao) in protecting against chemical liver injury through network pharmacology, molecular docking technology, and in vitro cell experiments. Methods: Network pharmacology was used to identify the common potential targets of P. Radix and chemical liver injury. Molecular docking was used to fit the components, which were subsequently verified in vitro. A cell model of hepatic fibrosis was established by activating hepatic stellate cell (HSC)-LX2 cells with 10 ng/mL transforming growth factor-β1. The cells were exposed to different concentrations of total glucosides of paeony (TGP), the active substance of P. Radix, and then evaluated using the cell counting kit-8 assay, enzyme-linked immunosorbent assay, and western blot. Results: Analysis through network pharmacology revealed 13 key compounds of P. Radix, and the potential targets for preventing chemical liver injury were IL-6, AKT serine/threonine kinase 1, jun proto-oncogene, heat shock protein 90 alpha family class A member 1 (HSP90AA1), peroxisome proliferator activated receptor gamma (PPARG), PTGS2, and CASP3. Gene Ontology (GO) enrichment analysis indicated the involvement of response to drugs, membrane rafts, and peptide binding. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the main pathways involved lipid and atherosclerosis and chemical carcinogenesis-receptor activation. Paeoniflorin and albiflorin exhibited strong affinity for HSP90AA1, PTGS2, PPARG, and CASP3. Different concentrations of TGP can inhibit the expression of COL-Ⅰ, COL-Ⅲ, IL-6, TNF-α, IL-1β, HSP-90α, and PTGS2 while increasing the expression of PPAR-γ and CASP3 in activated HSC-LX2 cells. Conclusion P. Radix primarily can regulate targets such as HSP90AA1, PTGS2, PPARG, CASP3. TGP, the main active compound of P. Radix, protects against chemical liver injury by reducing the inflammatory response, activating apoptotic proteins, and promoting the apoptosis of activated HSCs.

Objective To explore the influencing factors of home pulmonary rehabilitation for lung transplant re-cipients,so as to provide a basis for the construction of targeted intervention for home rehabilitation.Methods From August to November 2023,the purposive sampling was used to select 20 cases of lung transplant recipients for semi-structured interviews.Data was analyzed by traditional content analysis method based on capability,opportunity,and motivation-behavior model.Results Facilitators of rehabilitation behavior included opportunity factors(rehabilitation management of transplant center,multiple social support),motivational factors(perceived benefits,high self-efficacy,strong motivation,strong sense of responsibility,and good exercise habits).Barriers of rehabilitation behavior included ability factors(physical dysfunction,lack of knowledge),opportunity factors(poor rehabilitation environment,heavy eco-nomic burden),motivational factors(fear of exercise,uncomfortable activity experience,and lack of rehabilitation self-discipline).Conclusion The influencing factors of home pulmonary rehabilitation in lung transplant recipients are complex.Medical staff should take targeted measures to promote home rehabilitation to improve the exercise ability,quality of life,and clinical outcomes.

Purpose To investigate the clinical,imaging,pathological features,differential diagnosis and prognosis of em-bryonic dysplastic neuroepithelial tumor(DNT).Methods The clinical data of 33 DNT patients were collected.Immunohis-tochemical results of Olig2,NeuN,Syn,GFAP,IDH1,CD34,BRAF V600E,H3K27M and Ki67 were examined by EnVision method.Histopathological morphology and immunohistochemical features were retrospectively analyzed and relevant literature was reviewed synchronously.Results A total of 28 cases were fol-lowed up,including 10 females and 18 males.The age of onset was 4～57 years,with average 24.97 years.Refractory epilepsy was a common symptom.The lesions were mainly located in the supratentorial cortex,and most of them were well-defined,lobu-lated,cystic or cystic and solid.Microscopically,DNT was mainly composed of oligodendrocytes,neurons floating in the mucous matrix,and proliferative astrocytes.Calcification was rare,and no necrosis or microvascular hyperplasia was ob-served.Immunohistochemistry showed that neurons expressed NeuN and Syn,oligodendrocytes expressed Olig2,and prolifera-tive astrocytes expressed GFAP;p53 was mostly wild-type,and the proliferation index of Ki67 was low(mostly less than 4％).Conclusion DNT is a benign tumor with mixed glial and neu-ronal structures.Precise pathological diagnosis needs to be care-fully considered with imaging characteristics,microscopic mor-phology,immunohistochemistry and molecular test results if nec-essary.Prognosis after complete surgical resection is good.

Objective:To evaluate the guidelines on discharged health education for solid organ transplant recipients at home and abroad, analyze the characteristics of each guideline, so as to provide reference for the development of health education for organ transplantation in China.Methods:This was a guideline quality evaluation study. The guidelines on health education for discharged recipients with solid organ transplantation were searched on the websites of clinical practice guidelines, the websites of transplantation professional associations, and Chinese and English databases at home and abroad through computers. The search time limit was from January 1, 2011 to January 1, 2022. The quality of guidelines that met the inclusion and exclusion criteria was evaluated using the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) .Results:A total of 8 guidelines were included. The overall quality evaluation of the guideline was Grade A ( n=2) and Grade B ( n=6) . In terms of standardized scores in six areas of quality evaluation, the average values of scope and purpose, stakeholder involvement, rigour of development, clarity and presentation, applicability as well as editorial independence were 87.62% (70.37%-100.00%) , 75.46% (44.44%-97.22%) , 66.54% (43.75%-93.06%) , 90.16% (77.78%-96.30%) , 48.18% (20.83%-68.75%) and 74.13% (8.30%-97.22%) , respectively. The recommendations of the guidelines covered 9 aspects: team composition and support services, drug management, infection prevention, complication management, diet and nutrition, daily life and social reintegration, contraception and reproduction, psychological guidance and follow-up review. Conclusions:The development of guidelines for different types of solid organ transplantation varies. The overall quality of the guidelines needs to be improved and the content needs to be refined. In the future, we can learn from foreign high-quality guidelines to carry out localization practice, so as to build a health education related guideline for discharge of solid organ transplantation that is suitable for China's national conditions as soon as possible.

Objective:To investigate the outcomes and influencing factors of newly diagnosed prediabetic subjects aged 40 years and above in Guiyang.Methods:A total of 10 015 residents aged 40 years and above were recruited from the Yunyan community, Guiyang, from May to August 2011. Physical examination, laboratory measurements, and questionnaires were conducted. The follow-up survey was conducted in July 2014. A total of 2 530 newly diagnosed prediabetic subjects at baseline were included in the analysis.Results:The 3-year cumulative morbidity of diabetes mellitus was 14.3%, and the risk of diabetes mellitus in combined impaired fasting glucose(IFG)and impaired glucose tolerance(IGT)groups was significantly higher than that in isolated IFG(i-IFG)or isolated IGT(i-IGT)group( P<0.01). High baseline fasting plasma glucose, 2 h plasma glucose, and HbA 1C levels were the independent risk factors for the development of diabetes( OR=1.836, 95% CI 1.374-2.454; OR=1.398, 95% CI 1.261-1.550; OR=2.526, 95% CI 1.804-3.538, all P<0.01)and the inhibitory factors for reversion to normal glucose tolerance( OR=0.511, 95% CI 0.409-0.638; OR=0.715, 95% CI 0.661-0.774; OR=0.638, 95% CI 0.500-0.816, all P<0.01). High level of high density lipoprotein-cholesterol(HDL-C)was an promoting factor for reversion to normal glucose tolerance( OR=1.306, 95% CI 1.017-1.678, P=0.036). Subjects in the highest tertile of baseline HbA 1C level and body mass index(BMI)change before and after follow-up(ΔBMI=follow-up BMI minus baseline BMI)had a higher risk of diabetes mellitus than those in the lowest tertile( OR=2.398, 95% CI 1.733-3.322; OR=2.402, 95% CI 1.859-3.105, both P<0.01). The risk of diabetes mellitus in the significant weight loss group was reduced by 40.4% compared with the non-significant weight loss group when the subjects were divided into two groups according to the cutoff of the lower tertile of ΔBMI( RR=0.596, 95% CI 0.463-0.766, P<0.01). Conclusion:The risk of diabetes mellitus in combined IFG/IGT group was significantly higher than that in i-IFG or i-IGT group. High baseline fasting plasma glucose, 2 h plasma glucose, and HbA 1C levels were the independent risk factors for the development of diabetes. High level of HDL-C was an promoting factor for reversion to normal glucose tolerance. Weight loss can significantly reduce the risk of progression to diabetes in individuals with prediabetes.

Objective:To investigate the correlation between sleep duration, sleep timing and the risk of osteoporosis in postmenopausal women, to identify contributing mechanisms and guide the prevention and treatment of osteoporosis.Methods:A total of 5 449 postmenopausal women were included in this study. All participants completed questionnaires, medical examinations, blood test and the measurement of bone mineral density using calcaneal quantitative ultrasonography. After adjusting for potential confounders, logistic regression model was used to assess the association of sleep duration, sleep timing with the risk of osteoporosis. Results:In postmenopausal women, there were significant differences in sleep duration and timing among groups with different risk of osteoporosis( P<0.05). After controlling ages, BMI, diabetes, hypertension, dyslipidemia, smoking, alcohol consumption and physical activity, sleep duration was correlated with the risk of osteoporosis, long sleep duration(≥9 h)increased the risk of osteoporosis( OR=1.39, 95% CI 1.17-1.65, P<0.05)compared with the group with sleep duration of 7~8 hours. In analysis of the combined effect of sleep duration and sleep time on the risk of osteoporosis, compared with normal sleep duration(7-8 h)and normal sleep timing(22: 00-23: 00), long sleep duration(≥9 h)and normal sleep timing(22: 00-23: 00)increased the risk of osteoporosis( OR=1.38, 95% CI 1.01-1.87, P<0.05), which was higher in the group of long sleep duration(≥9 h)and late sleep timing(≥23: 00; OR=1.43, 95% CI 1.01-2.01, P<0.05). Conclusion:Long sleep duration(≥9 h)and late sleep timing(≥22: 00)are risk factors for the increased risk of osteoporosis in postmenopausal women, the late sleep timing leads to the higher risk.

At present, diabetes mellitus has become an increasingly serious disease which affects public health in the word. Clinical treatment of diabetes is mainly based on oral hypoglycemic drugs, insulin injections and lifestyle interventions (diet and exercise) . The new intervention method targeting intestinal microflora opens up new ideas for diabetes treatment. This article reviews the application of new intestinal microbial therapy (probiotic treatment, oral prebiotics/synbiotics, fecal microbiota transplantation) and treatment by regulating intestinal microflora (bariatric surgery, antibiotic therapy and traditional Chinese medicine) in diabetes. This article also summarized the nursing intervention based on intestinal microbial therapy so as to improve the understanding of the relationship between intestinal microflora and diabetes, and provide a reference for treatment and nursing care for type 2 diabetes.

Objective: To investigate the clinicopathological characteristics, therapy and prognosis of patients with pulmonary mucoepidermoid carcinoma. Methods: The clinical data of 87 patients diagnosed as pulmonary mucoepidermoid carcinoma at The First Affiliated Hospital of Zhengzhou University from April 2011 to May 2016 were retrospectively analyzed. The clinicopathological features were summarized and the prognoses were analyzed. Results: Among the 87 patients with lung mucoepidermoid carcinoma, 53 were male and 34 were female, the gender ratio between men and women was 1.56∶1.The ages of patients were from 16 to 79 years and the median age was 52.5 years. Seventeen cases were diagnosed as stage Ⅰ, 28 cases were stage Ⅱ, 26 cases were stage Ⅲ, 16 cases were stage Ⅳ.Thirty-six patients were examined by immunohistochemistry, of which 29 cases were cytokeratin (CK) 5/6 positive, 29 cases were CK7 positive, 10 cases were CK positive, 28 cases were p63 positive, 14 cases were p40 positive, 17 cases were thyroid transcription factor-1 (TTF-1) positive, 11 cases were NapsinA positive, 2 cases were epithelial membrane antigen (EMA) positive, 4 cases were CK8/18 positive, 3 cases were surfactant proteins A (SPA) positive, 1 case was CAM5.2 positive and 1 case was CK14 positive. Among the 87 patients, 34 cases were treated by operation alone, 23 cases were treated by operation combined with chemotherapy, 5 cases were treated by radiotherapy combined with chemotherapy, 14 cases were treated by chemotherapy alone, 2 cases were treated by particle implantation combined with chemotherapy, 2 cases were treated by local radiofrequency hyperthermia combined with chemotherapy, and 7 cases without special treatment.Five patients with brain metastasis were treated with cerebral radiotherapy combined with sequential chemotherapy. The 1-year, 2-year and 5-year survival rates of 87 patients were 90.7%, 81.6% and 46.3%, respectively. The median survival time was 60 months. The prognoses of patients with lung mucoepidermoid carcinoma were related with the clinical stage, smoking and operative therapy (all P<0.05). Conclusions The age distribution of patients with pulmonary mucoepidermoid is a wide range, the incidence of male is higher than that of female. The diagnosis of pulmonary mucoepidermoid carcinoma mainly relies on the morphological diagnosis and the immunohistochemical detection is non-specific. The prognoses of patients with lung mucoepidermoid carcinoma are related with clinical stage, smoking and operative therapy. For patients who are inoperable and with single distant metastasis, local radiotherapy, other local treatment and chemotherapy can significantly improve their prognoses.

Objective To explore the epidemiological characteristics of the prevalence and incidence of metabolic syndrome(MS) in subjects with different TSH levels, which can provide a certain clinical basis for the prevention and treatment of MS. Methods According to the reference range of the TSH test system in our hospital, the subjects were divided into TSH normal group and TSH elevation group. From May to August of 2011, the whole group sampling method was used to conduct a baseline survey of 10140 permanent residents aged 40 and above in Yunyan district of Guiyang City. A total of 9618 cases were included. The prevalence of MS and its components were calculated with different TSH levels at baseline. After eliminating 3926 MS in 2011, 5692 patients with no MS were followed up for 3 years. Incidence of MS and its components were compared among different TSH levels. The median follow-up was (38. 6 ± 1. 6) months and the completion rate was 75. 40％. Results The total crude and standard prevalence of MS were 40. 82％ and 34. 46％ respectively. The crude and standard prevalence of MS in TSH normal group were 39. 96％ and 33. 90％, respectively, and in TSH elevation group were 44. 3％ and 37. 56％respectively . The comparison of crude prevalence of MS between the two groups was statistically significant (P>0. 05) and the standard prevalence of MS in TSH elevation group was also higher than that in TSH normal group. After 3 years of follow-up, the total crude and standard incidences of MS were 22. 51％ and 20. 64％, respectively. The total crude and standard incidence of MS in TSH normal group were 22. 01％ and 20. 22％, respectively and in TSH elevatlon group were 24. 69％ and 23. 20％, respectively. There was no statistically significant difference between crude incidences of MS in two groups, but the standard incidence of MS in TSH elevation group was higher than that in TSH normal group. Binary Logistic regression analysis showed that there was a positive correlation between TSH and incidence of MS in TSH elevation group. Conclusion Higher than normal levels of TSH may increase the prevalence and incidence of MS and its some components.
