Adreno-cortical carcinoma(ACC)is an uncommon tumor,some of them may produce excessive steroid hormone.The prognosis of ACC is quite poor and current treatment options are relatively limited,especially for pa-tients whose tumor is metastatic and difficult to remove by surgical operation.This makes the management of ACC challenging.Existing studies have shown that the mechanisms of ACC are complex.The molecular changes happen in adrenocortical development and homeostasis may explain the occurrence of ACC.This review focuses on recent studies and summarizes the genetic and molecular mechanism changes that potentially associated with ACC in the development process of the adrenal cortex and multi-omics studies,including genomic changes,epigenetic changes,differences in non-coding RNA,immune microenvironment and features found through multi-omics analy-sis.This information may support screening of therapeutic targets of ACC in future.

Objective To test the reliability and validity of the Chinese version of the Caregiver Contri-bution to Self-Care of Chronic Illness Inventory in the caregivers of elderly patients with COPD.Methods The general information questionnaire and the Chinese version of the Caregiver Contribution to Self-Care of Chronic Illness Inventory were used to conduct questionnaire survey on 220 caregivers of elderly patients with COPD treated or hospitalized in the respiratory medicine department of a tertiary hospital in Hebei Province from October 2022 to February 2023,and the reliability and validity of the scale were tested.Results The i-tem-level content validity index was 0.833-1.000,the content validity index at the level of unanimity scale was 0.842 and the content validity index of the average scale level was 0.973.The confirmatory factor analysis showed that all the fitting indicators of the total scale and the caregiver's contribution to self-care mainte-nance,monitoring contribution and management contribution subscale were within the acceptable range.The Cronbach's α coefficients of the total scale and the three subscales were 0.918,0.865,0.830 and 0.897,re-spectively.The split-half reliabilities of the total scale and the three subscales were 0.843,0.855,0.842 and 0.906,respectively.The test-retest reliabilities of the total scale and the three subscales were 0.849,0.734,0.751 and 0.773,respectively.Conclusion The Chinese version of the Caregiver Contribution to Self-Care of Chro-nic Illness Inventory has good reliability and validity,and can be used as a reliable tool to measure the caregivers con-tribution to elderly COPD patients self-care.

Objective To explore the effect of sling exercise with Tuina therapy on kinesiophobia in old patients with lumbar disc herniation,and analyze the mechanism based on brain-bone axis. Methods A total of 56 old patients with chronic lumbar disc herniation and kinesiophobia were selected from the Reha-bilitation Hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September,2022 to December,2023;and randomly divided into control group(n=28)and experimental group(n=28).The control group accepted conventional exercise therapy,while the experimental group accepted sling exercise with Tuina therapy,for four weeks.They were assessed with simplified Chinese version of Tampa Scale of Kinesiophobia(TSK),Japanese Orthopaedic Association score(JOA)and Visual Analogue Scale for pain(VAS)before and after treatment,while the bone mineral density(BMD)was tested,the levels of osteoprote-gerin(OPG),norepinephrine(NE)and corticosteroids(Cor)in serum were measured,and the median frequency(MF)of weak-link erector spinae was detected with surface electromyography. Results Two cases dropped off in the control group,and one in the experimental group.The scores of all the assessment improved in both groups after treatment(|t|>14.168,P<0.001),as well as the serum levels of OPG,NE and Cor(|t|>2.103,P<0.05),BMD(|t|>2.726,P<0.05),and MF of erector spinae(|t|>14.736,P<0.001);all of them were better in the experimental group than in the control group(|t|>2.154,P<0.05). Conclusion Sling exercise with Tuina therapy can improve the pain and kinesiophobia of lumbar disc herniation in the old adults,which may promote the recovery of physical and mental function through regulating the levels of hor-mones and neurotransmitters related to the brain-bone axis.

Objective:To explore the current status of post management for orthopedic specialist nurses in Beijing, so as to provide reference for formulating orthopedic specialist nurse management systems.Methods:Purposive sampling was used to select 254 orthopedic specialist nurses who participated in the Orthopedic Specialist Nurse Qualification Certification Training Course organized by the Beijing Nursing Association from 2014 to 2020. A survey was conducted using the self-developed Post Management Questionnaire and Job Satisfaction Questionnaire.Results:254 orthopedic specialist nurses came from 46 hospitals in Beijing. 92.9% (236/254) of orthopedic specialist nurses had a bachelor's degree or higher, 69.3% (176/254) of specialist nurses had intermediate or higher professional titles, and hospitals with 67.7% (172/254) of specialist nurses established post management systems or policies. The work of specialist nurses mainly focused on clinical nursing, and also undertook nursing teaching, nursing quality management, organizing nursing rounds, and clinical case nursing. The main factors hindering the development of orthopedic specialist nurses were the heavy workload of clinical affairs, lack of clear job evaluation indicators, and lack of clear career development direction.Conclusions:The post management of orthopedic specialist nurses in Beijing has gradually been carried out, but there is still room for improvement in the implementation of advanced nursing practice activities, assessment and evaluation, and special incentives for specialist nurses. Managers should further establish a sound, scientific, and effective management system, fully leverage the advanced clinical nursing practice role of orthopedic specialist nurses, and promote the scientific application of orthopedic specialist nurses.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To develop an Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, a preliminary scale draft was formed through a literature review, three rounds of Delphi expert consultation, and a pre-survey. Using convenience sampling, 311 hemodialysis nurses were selected for a survey from December 2022 to February 2023 for item analysis, exploratory factor analysis and reliability testing. Another survey was conducted on 260 hemodialysis nurses from February to June 2023 for confirmatory factor analysis, convergent validity, and discriminant validity testing.Results:The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses included three subscales and five dimensions, with a total of 33 items. The content validity index at the item level was 0.867 to 1.000, and the content validity index at the scale level was 0.992. After exploratory factor analysis, two, one, and two common factors were extracted from the knowledge, attitude, and practice subscales, with cumulative variance contribution rates of 70.114%, 75.192%, and 67.467%, respectively.Confirmatory:factor analysis showed that the model fitted well. The Cronbach's α coefficients of the three subscales were 0.929 to 0.943, the half reliability coefficients were 0.861 to 0.903, and the retest reliability coefficients were 0.824 to 0.874. Conclusions The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses has good reliability and validity and can be used to evaluate the physical examination ability of hemodialysis nurses for arteriovenous fistula.

Objective To explore the application effect of pulmonary rehabilitation exercise health education program based on contemplation-action-maintenance (CAM) theory in patients with chronic obstructive pulmonary disease (COPD). Methods A total of 90 COPD patients were selected as the study subjects and randomly divided into control group (n=45) and intervention group (n=45). A total of 5 patients were excluded, with 42 cases finally included in the intervention group and 43 cases in the control group. The control group received routine exercise health education, while the intervention group received pulmonary rehabilitation exercise health education based on the CAM theory. The Readiness for Hospital Discharge Scale (RHDS), Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3), Benefit Finding Scale (BFS), exercise adherence scale scores and exercise tolerance[6-minute walk test (6MWT)]were compared between the two groups. Results At discharge, the RHDS score of the intervention group was higher than that of the control group, with a statistically significant difference (P < 0.05). At discharge and at 1 month as well as 3 months after discharge, the BREQ-3 and BFS scores of the intervention group were higher than those of the control group, with statistically significant differences (P < 0.05). At 1 month and 3 months after discharge, the exercise adherence scale scores and 6MWT distances of the intervention group were higher or longer than those of the control group, with statistically significant differences (P < 0.05). Conclusion The pulmonary rehabilitation exercise health education program based on CAM theory can improve the discharge readiness and exercise motivation of COPD patients, enhance their awareness of disease benefit and exercise compliance, and improve the exercise endurance of patients.

This article briefly introduced the platform from five aspects: the excavation of the experience of famous TCM doctors in modern times, the summary of the academic thoughts of ancient medical cases, the analysis of the law of diagnosis and treatment of specialized diseases, the regularity of a single drug and drug pairs, and the exploration of the compatibility of TCM prescriptions.

Objective:To investigate the etiology, clinical features and treatment of familial exudative vitreoretinopathy (FEVR) secondary glaucoma.Methods:A retrospective clinical study. From January 1, 2016 to January 1, 2022, 15 patients (17 eyes) were diagnosed with FEVR secondary glaucoma in Beijing Tongren Hospital, Capital Medical University were included in the study. All patients underwent systematic ophthalmological evaluation. According to the patient's age, visual acuity, intraocular pressure, anterior segment, vitreous body and retina condition, the choice of translimbal lensectomy combined with vitrectomy, goniectomy, cyclophotocoagulation, intravitreal injection of anti-vascular endothelial growth factor (VEGF) treatment were chosen. The follow-up time was 3 to 37 months. The clinical characteristics of the affected eye, and the changes of intraocular pressure, anterior chamber depth and complications after surgery were observed.Results:Among the 15 patients, there were 11 males with 13 eyes, and 4 females with 4 eyes. Age was 6.14±7.37 years old. FEVR stages 2B, 3B, 4A, 4B, 5A, and 5B were 1, 1, 5, 6, 3, and 1 eye, respectively. The intraocular pressure of the affected eye was 42.74±9.06 mm Hg (1 mm Hg=0.133 kPa). All eyes had shallow anterior chamber and angle closure, anterior or posterior iris adhesions, lens opacity, retinal detachment, iris neovascularization in 4 eyes, and vitreous hemorrhage in 2 eyes. Sixteen eyes were treated with translimbal lensectomy combined with vitrectomy and goniotomy, of which 8 eyes were treated with anti-VEGF treatment; 1 eye was treated with cyclophotocoagulation combined with anti-VEGF treatment. After operation, the intraocular pressure of 16 eyes returned to normal range, and the depth of anterior chamber of 16 eyes returned to normal, and no obvious complications occurred.Conclusions:The main etiology of secondary glaucoma in FEVR is the structural and functional abnormalities of the anterior chamber and angle, which are found in the 2B and above stages of FEVR. The lensectomy and vitrectomy via limbal approach can effectively control the intraocular pressure and restore the anterior chamber, with no serious complications.

Objective:To review the outcome of intravitreous anti-vascular endothelial growth factor (VEGF) treatment in patients with X-linked retinoschisis (XLRS) complicated with vitreous hemorrhage (VH).Methods:A retrospective clinical study. From March 1, 2016 to April 1, 2022, 18 patients (19 eyes) diagnosed with XLRS complicated with vitreous hemorrhage in Beijing Tongren Hospital, Capital Medical University of Eye Center were included. All the patients were male, with a median age of 7.05±3.8 years. Best corrected visual acuity (BCVA) and wide-angle fundus photography were performed in all the patients. BCVA was carried out using international standard visual acuity chart, and converted into logarithm of minimum resolution angle (logMAR) in statistics analysis. According to whether the patients received intravitreal injection of ranibizumab (IVR), the patients were divided into injection group and observation group, with 11 eyes in 10 cases and 8 eyes in 8 cases, respectively. In the injection group, 0.025 ml of 10 mg/ml ranibizumab (including 0.25 mg of ranibizumab) was injected into the vitreous cavity of the affected eye. Follow-up time after treatment was 24.82±20.77 months. The VH absorption time, visual acuity changes and complications were observed in the injection group after treatment. Paired sample t test was used to compare BCVA before and after VH and IVR treatment. Independent sample t test was used to compare the VH absorption time between the injection group and the observation group. Results:LogMAR BCVA before and after VH were 0.73±0.32 and 1.80±0.77, respectively. BCVA decreased significantly after VH ( t=-3.620, P=0.006). LogMAR BCVA after VH and IVR were 1.87±0.55 and 0.62±0.29, respectively. BCVA was significantly improved after IVR treatment ( t=6.684, P<0.001). BCVA records were available in 5 eyes before and after IVR, and the BCVA values after VH and IVR were 0.58±0.31 and 0.48±0.20, respectively, with no statistically significant difference ( t=1.000, P=0.374). BCVA increased in 1 eye and remained unchanged in 4 eyes after treatment. BCVA records were available in 5 eyes before VH and after VH absorption in the 8 eyes of the observation group. LogMAR BCVA before VH and after VH absorption were 0.88±0.28 and 0.90±0.26, respectively, with no significant difference ( t=-1.000, P=0.374). After VH absorption, BCVA remained unchanged in 4 eyes and decreased in 1 eye. The absorption time of VH in the injection group and the observation group were 1.80±1.06 and 7.25±5.04 months, respectively. The absorption time of VH was significantly shorter in the injection group than in the observation group, the difference was statistically significant ( t=-3.005, P=0.018). Multivariate linear regression analysis showed that IVR treatment was significantly correlated with VH absorption time ( B=-6.66, 95% confidence interval -10.93--2.39, t=-3.40, P=0.005). In the injection group, VH recurrence occurred in 1 eye after IVR treatment. Vitrectomy (PPV) was performed in one eye. In the 8 eyes of the observation group, VH recurrence occurred in 2 eyes, subsequent PPV in 1 eye. The rate of VH recurrence and PPV was lower in the injection group, however, the difference was not statistically significant( P=0.576, 1.000). In terms of complications, minor subconjunctival hemorrhage occurred in 2 eyes and minor corneal epithelial injury occurred in 1 eye in the injection group, and all recovered spontaneously within a short time. In the injection group, 9 eyes had wide-angle fundus photography before and after IVR treatment. There was no significant change in the range of peripheral retinoschisis after treatment. No obvious proliferative vitreoretinopathy, infectious endophthalmitis, retinal detachment, macular hole, complicated cataract, secondary glaucoma or other serious complications were found in all the treated eyes, and there were no systemic complications. Conclusion:Intravitreous anti-VEGF treatment may accelerate the absorption of vitreous hemorrhage in patients with XLRS. No impact is found regarding to the peripheral retinoschisis.
