Objective To develop the assessment scale of proactive health behavior ability for the disabled elderly in nursing homes and to test its reliability and validity.Methods The first draft of the scale was formed by literature review,qualitative interviews and Delphi method.From December 2023 to March 2024,525 disabled elderly people from 9 nursing homes in Sichuan Province and Chongqing City were selected as the survey subjects,and item analysis and reliability and validity test were carried out on the scale.30 disabled elderly people were re-investigated after 2 weeks to calculate the retest reliability of the scale.Results The scale consisted of 4 dimensions and 27 items.Exploratory factor analysis extracted 4 common factors,with the cumulative vanance contribution rate of 65.992％,and confirmatory factor analysis showed that the modified model fitting index was within acceptable range.The content validity index at item level was 0.917-1.000,and that at scale level was 0.997.The Cronbach's α coefficient,test-retest reliability and split-half reliability of the total scale were 0.944,0.997 and 0.882,respectively.Conclusion The scale has good reliability and validity,and it can be used to evaluate the proactive health behavior ability of the disabled elderly in nursing homes.

Burkitt lymphoma is a highly aggressive B-cell lymphoma and the fastest proliferating human malignant tumor.If the disease is found in the early stage,the patient could have a high possibility to be cured successfully,whereas the prognosis is poor in the late stage.Burkitt lymphoma can occur in children and adults,and it is categorized as local(Africa),sporadic,and immunodeficiency associated type.Sporadic Burkitt lymphoma mainly affects children and ado-lescents,and the most common initial sites are abdominal organs and lymph nodes.Sporadic Burkitt lymphoma manifested by initial oral and maxillofacial lesions is rela-tively rare.Here,a case of pediatric sporadic Burkitt lym-phoma,with oral and maxillofacial lesions as the first symptoms,was reported.The patient was treated in the Department of Periodontology,Shandong University School and Hospital of Stomatology.After timely checkup was pro-vided,the patient was transferred to another hospital and had good results.In this article,an incidence of Burkitt lympho-ma,with oral and maxillofacial lesions as the first symptom,was reviewed to provide reference for oral clinicians to achieve early diagnosis and treatment of patients with Burkitt lymphoma with oral diseases and improve the success rate of treatment.

Objective:To evaluate the clinical efficacy of omalizumab in the treatment of patients with chronic spontaneous urticaria accompanied by other allergic diseases.Methods:Clinical data were retrospectively collected from 74 patients, who were clinically diagnosed with chronic spontaneous urticaria and other allergic diseases, and received subcutaneous injections of omalizumab in the Department of Allergy, Tianjin Medical University General Hospital from June 2020 to September 2022. Types of allergic diseases, serum total IgE (tIgE) and allergen-specific IgE (sIgE) levels before treatment, treatment outcomes and adverse drug reactions were analyzed. Differences before and after treatment were assessed using paired t-test and Wilcoxon signed-rank sum test. Results:A total of 74 patients with chronic spontaneous urticaria were involved, including 29 with complicated allergic asthma (39.2%) , 61 with complicated allergic rhinitis (82.4%) , 6 with complicated atopic dermatitis (8.1%) , and 4 with food allergy (5.4%) . Before treatment, elevated serum tIgE or sIgE levels were observed in 44 (59.5%) patients. After the first omalizumab treatment, the urticaria control test (UCT) score significantly increased compared with that before treatment (16.00 [13.0.0, 16.00] vs. 6.00 [5.75, 9.00], Z = 7.39, P < 0.001) ; after 4 sessions of the omalizumab treatment, 82.5% (33/40) of the patients achieved complete control of urticaria symptoms or showed complete response. After omalizumab treatment, asthmatic attacks were decreased in 29 patients with allergic asthma, and asthma control test (ACT) scores significantly increased compared with those before treatment (21.07 ± 2.88 points [after the first treatment] vs. 18.48 ± 3.20 points [before treatment], t = 8.87, P < 0.001) ; among 61 patients with allergic rhinitis, global rhinitis symptom-based visual analog scale (VAS) scores (before treatment: 5.89 ± 1.29 points; after the first treatment: 3.28 ±1.46 points) and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores (before treatment: 60.10 ± 20.53 points; after the first treatment: 37.26 ± 18.83 points) both significantly decreased after the first treatment ( t = 15.04, 10.01, respectively, both P < 0.001) , and rhinitis symptoms were relieved at the same time; skin itching was relieved in 4 patients with atopic dermatitis, and allergic symptoms after contact with food allergens were also relieved in the 2 patients with food allergy after omalizumab treatment. During the treatment, only 1 patient experienced erythematous swelling, induration, and pain at the injection site. Conclusions:In the treatment of chronic spontaneous urticaria accompanied by allergic diseases, the use of omalizumab not only effectively improved urticaria symptoms, but also well controlled allergic diseases, with a good safety profile. Multiple benefits may be achieved by the use of omalizumabin in patients with chronic spontaneous urticaria accompanied by other allergic diseases.

Objective This study aims to explore the formation of the dilemma of"giving care"for disabled elderly people in nursing homes from the perspective of active health.Methods Purposive sampling was used to select caregivers and disabled elderly people from a nursing home in Chongqing as research subjects from July 2022 to December 2022.One-on-one in-depth interviews were conducted and Colaizzi's 7-step thematic analysis method was employed to collect and analyze the interview data.Results 4 themes were identified:①the dominance of the"giving"care concept,including the cultural thoughts of filial piety,passive acceptance of care characteristics and consumer psychology regarding paid services;②insufficient"participation"care ability,including lack of knowledge regarding active health and a weakening of skills to promote participation;③the hindrance to"transformation"of care models,including objective limitations in terms of human resources and delays in adapting aging environments;and ④the decline in"utilization"of internal abilities,including excessive avoidance of potential risks,a heavy workload of care and poor quality of individual care.Conclusion The formation of the dilemma of"giving care"for disabled elderly people in nursing homes is affected by multiple factors such as social background,service system,supply resources,and management mode.Transforming disabled elderly individuals from a state of"passive giving care"to"active participation in their health"is an important measure to realize the concept of positive aging and healthy aging.

Objective:To analyze the change trend of survival rate after hip fragility fracture in Tianjin Hospital from 2015 to 2021, and the influence of gender, marital status, age and number of complications on survival rate.Methods:From January 1, 2015 to December 31, 2021, a total of 12,570 patients with fragility fracture of hip were retrieved, including 3,934 males and 8,636 females. The age at admission was 74.11±9.50 years and 74.62±8.99 years respectively. By comparing the ID number with the Tianjin population information database, 2,054 cases died, including 804 males and 1,250 females, aged 81.34±7.88 years and 81.92±7.42 years respectively at the time of death. Acquire the patient's survival status, calculate the cumulative survival rate at 3 month intervals, study the change rule of the cumulative survival rate over time, and use Kaplan-Meier method to calculate the cumulative survival rate of the whole population and the impact of gender, marital status, age, and number of complications on the survival rate.Results:The median survival time of all the dead people after fracture was 13(3, 31) months, including 11(2, 27) months for males and 15(4, 32) months for females. Joinpoint regression showed that 9 months after the hip fragility fracture was the break point of the survival rate. The mortality rate changed significantly within 9 months after fracture (the annual change rate was 47%), and slowed down 9 months later (the annual change rate was 1%). There was a statistically significant difference in trend detection before and after the break point ( P<0.05). The age at admission was 80.11±7.71 years for the dead and 73.36±9.01 years for the non dead, with a statistically significant difference ( t=31.80, P<0.001). After normalization, the number of complications was 0.20±0.93 among the dead and 0.00±0.87 among the non dead, with a statistically significant difference ( t=88.81, P<0.001). The survival rate of men after hip fracture is lower than that of women, the number of people without spouse is lower than that of people with spouse, the number of people with more than 70 years old is lower than that of people with less than 70 years old, and the number of complications ≥2 people is lower than that of people with less than 1 complication, all of which are statistically significant ( P<0.05). Conclusion:The survival rate within 9 months after the occurrence of hip fragility fracture decreased significantly, and it needs to be tracked and managed for at least 9 months to effectively reduce the risk of death; Male, no spouse, age>70 years old, number of complications ≥2 will increase the risk of death after hip fragility fracture, leading to reduced survival rate of patients.

Objective:To explore the efficacy and safety of unrelated mismatched hematopoietic stem cell transplantation(HSCT)for thalassemia major.Methods:For this retrospective cohort study, 15 patients with β-thalassemia major underwent unrelated mismatched HSCT between January 2018 and April 2022. There were 8 males and 7 females with a median age of 7(3-12)years and a median ferritin level of 3 417.3(223-14 485)μg/L. The conditioning regimens on the basis of fludarabine(Flu), busulfan(Bu)and cyclophosphamide(CTX)and GVHD prophylaxis on the basis of cyclosporine(CsA), mycophenolate mofetil(MMF), anti-human thymocyte immunoglobulin(ATG)plus low-dose post-cyclophosphamide(PTCy)and mesenchymal stem cells were offered.Results:Up until April 1, 2022, 15 children were successfully implanted during a median follow-up period of 24.1(11-49)months and all of them achieved stable donor chimerism. The median time to neutrophil and platelet engraftment were 12(11-22)and 14(8-38)days respectively. Except for 2 deaths, 13 cases survived. The estimated 2-year probability of overall survival(OS)and thalassemia-free survival(TFS)were both 86.67%. There were 5 cases of acute graft versus host disease (aGVHD) below grade Ⅱ, 2 cases of grade Ⅲ to Ⅳ aGVHD, and 3 cases of localized chronic graft versus host disease (cGVHD) after transplantation. No gengralized cGVHD occurred. Both cytomegalovirus and Epstein-Barr virus were activated in five recipients.Conclusions:Unrelated mismatched donor HSCT is both safe and feasible for thalassemia major.

Objective To demonstrate the changes in flexor digitorum and extensor digitorum tension in the affected hands with shear-wave elastography (SWE) before and after manual digitorum sensory stimulation (MDSS) in hemiplegic patients with stroke. Methods A total of 51 hemiplegic post-stroke inpatients in the Department of Rehabilitation Medicine in Second Hospital of Anhui Medical University from April to June, 2020, underwent MDSS completed by a researcher who used a bare thumb and index finger to squeeze each nail bed as well as the sides of each fingertip in the affected hand. The stimulation intensity was the minimum that could cause finger extension without obvious pain, and the interval between two stimulations was five to ten seconds. Muscular tension of the flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus and extensor digitorum were assessed with modified Ashworth Scale (MAS) and shear-wave velocity (SWV) of SWE on the affected side before and immediately after MDSS. MAS score was -1 as low muscular tension. Results The MAS scores of all the muscles significantly reduced after MDSS (|Z| > 2.843, P < 0.001); while the changes of SWV were not significantly in all the muscles with initially MAS score of 0 or -1 (t < 1.052, P > 0.05), and it reduced in those muscles with initial MAS scores of one to three (t > 2.672, P < 0.05). The SWV were positively correlated with the MAS scores both before and after MDSS (r > 0.334, P < 0.05). Conclusion MDSS can effectively, immediately, and safely relieves muscle spasms of the flexor digitorum and facilitate active finger extension in the affected hand for hemiplegic patients with stroke. SWE is useful for quantitatively and objectively evaluating muscular tension in the affected hand for hemiplegic patients with stroke.

Objective:To explore the safety and advantages of non-cryopreserved sibling umbilical cord blood hematopoietic stem cell transplantation for major thalassaemia in children.Methods:From October 2016 to June 2021, 9 patients with major beta thalassaemia received non-cryopreserved hematopoietic stem cell transplantation of sibling umbilical cord blood at Zhongshan Hospital of Xiamen University. The pretreatment scheme, the process of stem cell implantation and follow-up were analyzed and summarized.Results:Among the 9 cases, there were 5 males and 4 females with a median age of 4(2~11)years. Median level of ferritin was 2 997(1 936~5 512)μg/L. At gestational weeks 12~16, each patient's mother underwent villi testing to confirm that the donor without thalassaemia major was complete HLA-matched with the patient. All of them received an intensive conditioning regimen made up of cyclophosphamide(CTX), fludarabine and busulfan(Bu). Graft-versus-host disease(GVHD) was prevented by cyclosporine A(CSA)and mycophenolate mofetil(MMF)with or without methotrexate(MTX). Except for one failed implant, 8 cases were successfully engrafted. Median time of neutrophil implantation was 19.5(15~26)days, median time of platelet implantation 32(22~34)days and median time of erythrocyte implantation 30.5(18~37)days. Up until September 1, 2021, the median follow-up period was 27(3~59)months and the rate of successful engraftment 88.89%. There was no transplant-related mortality. Overall survival was 100% and thalassaemia-free survival 88.89%. Two patients developed grades Ⅱ skin acute GVHD(22.2%). No grade Ⅲ-Ⅳ GVHD or chronic GVHD occurred. Epstein-Barr virus infection occurred in 1 case.No infection of cytomegalovirus occurred.Conclusions:For major thalassaemia in children, stem cell transplantation of non-cryopreserved sibling cord blood is both safe and feasible with a high implantation rate and a low incidence of GVHD.

ObjectiveTo investigate the changes of surface electromyography (sEMG) of the flexors and extensors of the affected fingers after manual digitorum sensory stimulation (MDSS) in the hemiplegic patients after stroke. MethodsFrom April to August, 2020, 50 stroke patients in Department of Rehabilitation Medicine, the Second Hospital of Anhui Medical University accepted MDSS on the nail beds and the third knuckles of affected fingers, until the fingers extended actively. The tension of affected flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were assessed with modified Ashworth Scale (MAS) before and immediately after stimulation; while the root mean square (RMS) of sEMG of bilateral flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were recorded. ResultsThe MAS score of all the muscles decreased after stimulation (|Z| > 2.699, P < 0.01), while the RMS of affected extensor digitorum increased (t = -2.069, P < 0.05). Compared with the unaffected ones, RMS of affected flexor pollicis brevis and extensor digitorum decreased before and after stimulation (t > 2.450, P < 0.05). ConclusionMDSS may immediately relieve the spasm of flexors of hemiplegic fingers after stroke, which associates with the promoting muscle strength of the extensors.
