Objective To evaluate a combination of interventional treatment and surgical exploration for acute lower limb ischemic disease.Methods We reviewed 42 cases admitted from July 2007 to January 2010,all patients complained pain,paralysis,pulselessness,pallor and paresthesia.After Fogarty thrombectomy angiography was taken in DSA room.Patients with angiostenosis greater than 50％ were then managed by interventional treatment(CDT,PTA,Stenting).Results Lives were saved in all patients,40 lower limbs were saved,and 2 patients received below knee amputation.The amputation rate was 4.76％.Dorsal or(and)posterior tibial artery of foot was felt in 33 patients,symptoms significantly improved.The other 7 patients still had painful and paralysis on the diseased limb.Conclusions The interventional treatment and surgical operation in acute lower limb ischemic disease is safe and result is satisfactory,which can improve the long-term patency and salvage rate of the lower limb.

Hospital culture constitutes the core competitiveness of modern hospitals and serves as the intrinsic driving force for the development of public hospitals.It permeates and affects various aspects of hospital operations,including medical quality,modern management,scientific research and teaching,and talent cultivation.An advanced hospital culture is instrumen-tal in bolstering a hospital's core competitiveness,establishing a positive image,fostering harmonious doctor-patient relation-ships,and facilitating high-quality development.The First People's Hospital of Changzhou,under the guidance of Party-building theories,has adopted the"532"development strategy.The hospital has pursued a"Five Implementations"approach to cultivate its spirit,system,service,integrity,and brand.This strategy is pivotal in solidifying the ideological foundation among staff through the development of a robust spiritual culture.It has also enhanced the level of scientific management by strengthening in-stitutional culture,improved patient experience through the refinement of service culture,raised awareness in medical service by constructing a culture of integrity,and expanded industry influence by shaping a distinct brand culture.These efforts have contin-uously elevated the hospital's management standards and,patient experience,thus promoting its high-quality development.

Objective: To analyze the clinical characteristics of eperythrozoonosis complicated with hemophagocytic syndrome (HPS) in 4 children. Methods: Four patients diagnosed with eperythrozoonosis complicated with HPS in the Children's Hospital Affiliated Capital Institute of Pediatrics during the period from June 2014 to July 2016 were enrolled. The clinical manifestations, laboratory examination data and therapeutic strategies were analyzed. A literature search (search terms included 'eperythrozoonosis’ and 'hemophagocytic syndrome’) was conducted using CNKI, Wanfang database, Chinese biomedical literature database and PubMed to include recently published studies (searched from the database establishment to January 2017). Results: Four patients were included in the study. One was boy and the other three were girls. The age range of the 4 patients was between 9 months and 17 years (9 months, 2 years and 17 years, 11 months respectively). All the patients presented with recurrent high fever. During the course of fever, 3 patients presented with rash, and 2 patients presented with joint pain and swelling, which mimicked systemic juvenile idiopathic arthritis. Only 1 patient had the contact history of infectious disease. All patients had normal or decreased white blood cell count ((0.80-13.12)×10⁹/L), suffered from varied degrees of anemia and showed the increased C reactive protein (13.0-84.7 mg/L) anderythrocyte sedimentation rate (13-72 mm/1 h). Examination of peripheral blood smears confirmed eperythrozoonosis. After fever continued about 1 month, all the 4 patients rapidly progressed. Among the 4 patients, 1 patient died for giving up further therapy, and the other 3 patients completely recovered after treatment, including azithromycin for the treatment of eperythrozoonosis, and high-dose intravenous methylprednisolone pulse therapy and human immunoglobulin for the treatment of HPS. For the disease not satisfactory, the hemophagocytic lymphohistiocytosis-2004 (HLH-2004) protocol is given. After the hospitalization of 1 to 2 months, the conditions improved and the children were discharged from hospital. Three patients were followed up for 8 months to 2 years, and their conditions were stable. In the PubMed database, no report was found. Nine cases of children with eperythrozoonosis were found in CNKI, Wanfang database and Chinese biomedical literature database, and 1 case was complicated with HPS. These findings, taken together our report, provided the data of 5 children with eperythrozoonosis complicated with HPS (4 cases were younger than 2 years old). A patient had contact history of infectious disease. Five patientss showed fever of unknown origin. All the patients had severe eperythrozoonosis, and 2 cases at younger age died. Conclusions Children with eperythrozoonosis often present with the protracted fever of unknown origin, and clinical manifestations mimic those of juvenile idiopathic arthritis (systemic type). The patients with eperythrozoonosis of mild-to-moderate disease severity may have a good prognosis. Children with severe eperythrozoonosis, especially those HPS cases with early onset before 2 years old, may have high risk of mortality. Once the patient's condition aggravates in the course of fever, HPS should be highly suspected. For the patients with eperythrozoonosis complicated with HPS, early diagnosis and the combination of anti-infection with the treatment of HPS are crucial for a good prognosis. For the treatment of HPS, HLH-2004 protocol is recommended.

Objective: To report the clinical features of anti-MDA5 antibody positive juvenile dermatomyositis (JDM) complicated with severe interstitial lung disease (ILD). Methods: The clinical data of three patients, who was admitted to the Department of Rheumatology and Immunology, Children's Hospital of the Capital Institute of Pediatrics from September 2016 to July 2017, with anti-melanoma differentiation associated gene 5 (MDA5) antibody positive JDM complicated with ILD were retrospectively extracted and analyzed. Meanwhile, PubMed database, CNKI, Wanfang database and China Biology Medicine disc (from their establishment to February 2019) with the key words "juvenile dermatomyositis" "interstitial lung disease" , and "anti-MAD5 antibody" both in English and Chinese were searched. Results: There were 2 females and 1 male (P1-P3), aged from 10 years 3 months to13 years 4 months, the time from onset to diagnosis were 2 months, 4 months and 10 months. All presented with rash. One of them had decreased muscle strength, and two had decreased activity tolerance. Creatine kinase was 588, 915 and 74 U/L, and serum ferritin were 1 792, >2 000 and 195.4 μg/L. All three patients had positive anti-MDA5 antibodies. At the time of diagnosis, all of them had ILD, pneumothorax and mediastinal emphysema, but had no respiratory symptoms. All three patients received oral methylprednisolone and cyclophosphamide pulse therapy, while human immunoglobulin was given only to P1 and P2. P1 developed rapid progressive pulmonary interstitial disease (RPILD) and died of respiratory failure after 2 months. While P2 and P3 were followed up for 1 to 2 years, who had complete remission, as anti-MDA5 antibody turned to negative and ILD improved significantly. Ten related reports in literature were retrieved, without reported Chinese cases, and most cases initiated with rash and very likely complicated with arthritis. Some of them were more likely to have ILD rather than muscle weakness. It also showed that Japanese JDM children had higher rate of positive anti-MDA5 antibody than patients from the U.S. and U.K., and are more susceptible to ILD and RPILD. The mortality rate of patients with RPILD is extremely high. Conclusions The cases of JDM with positive anti-MDA5 antibody mainly presented with rash and mild muscle weakness, and could be complicated with ILD, pneumothorax and mediastinal emphysema without respiratory symptoms at early stage. Anti-MDA5 antibody titer is related to disease activity and can turn to negative after treatment.

Objective:To systematically review the current situation and risk factors of social isolation among elderly people in Chinese communities.Methods:The research on social isolation of elderly people in Chinese communities was electronically searched on China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, PubMed, Embase, Web of Science, and Cochrane Library. The search period was from database establishment to August 1, 2023. Two researchers independently conducted literature screening, quality evaluation, and data extraction, and used Stata 17.0 software to conduct Meta-analysis on the incidence and risk factors of social isolation among elderly people in the community.Results:A total of 29 articles were included, with a total of 49 713 samples. Meta-analysis showed that the incidence of social isolation among elderly people in Chinese communities was 29.5%. Advanced age, education below college level, poor self-rated health, lack of exercise, coexistence of chronic diseases, impaired daily living activities, hearing loss, depression, lack of spouse, low family care, low social support, and low social participation were the main risk factors for social isolation among elderly people in the community ( OR ranging from 1.57 to 3.34, P<0.05) . Conclusions:The incidence of social isolation among elderly people in Chinese communities is high, and there are many risk factors. Medical and nursing staff should strengthen early screening for social isolation among the elderly and provide early intervention for the risk factors.

Objective To summarize the clinical characteristics of Beh?et's disease (BD) in children with gastrointestinal involvement. Methods We retrospectively analyze the children BD with gastrointestinal involvement who were diagnosed in our hospital in recent 10 years. Results Twenty-two children were identified. The average age of onset was(6.1±4.0) years. The time from disease onset to clinical diagnosis was (1.2±2.1) years on average. Fifteen children had abdominal pain, diarrhea and hematochezia. Seven cases had positive endoscopic findings without any gastrointestinal symptoms. Twenty cases received corticosteroids therapy, 13 cases of them were treated with Cyclophosphamide/Methotrexate (CTX/MTX), 3 refractory cases were treated with biologics. Patients were followed up for (28±32) month on average. Eight patients' condition was stable, 7 patients were refractory, 3 patients died, 4 patients were lost to follow-up. At the same term, 5 patients without gastrointestinal involvement who received corticosteroids and CTX/MTX therapy were stable. Conclusion It is difficult to diagnose children BD at early stage. Gastrointestinal involvement may not be found, while the gastrointestinal endoscopy is of great importance in the diagnosis of the disease. Gluco-corticoid combined with immunosuppressive agents are effective. As to refractory patients, biological agent might be used although the recurrence is common. Compared with BD without gastrointestinal involvement, children BD with gastrointestinal involvement have serious condition and poor prognosis.

Objective:To observe the clinical efficacy of intra-articular injection with Triamcinolone acetonide on the treatment of juvenile idiopathic arthritis (JIA).Methods:The clinical data of 26 children diagnosed with JIA undergoing the intra-articular injection of Triamcinolone acetonide for the joints with obvious swelling and pain at the Children′s Hospital Affiliated to Capital Institute of Pediatrics from October 2018 to December 2019 who were retrospectively analyzed.Erythrocyte sedimentation rate (ESR) and C-reactive protein(CRP) were tested before and after the application of Triamcinolone acetonide.Detailed clinical manifestations were recorded.The nonparametric Kruskal- Wallis test was used to compare the differences in clinical evaluation indicators and changes in laboratory tests at diffe-rent treatment times. Results:Among the 26 children, 8 were boys and 18 were girls.After the intra-articular injection of Triamcinolone acetonide, 9 cases (34.62%) achieved complete remission, 15 cases(57.69%) achieved partial remission, and 2 cases (7.69%) were not responsive to the intra-articular injection.The overall therapeutic efficacy was 92.31%.Compared with pre-treatment period, from 4 weeks after treatment, assessment of disease activity by the physicians and parents of the children was significantly improved after 4-week treatment, and the number of active joints, ESR and CRP and the Juvenile Arthritis Disease Activity Score with 27 joints (JADAS 27) gradually decreased, and the differences were statistically significant (all P<0.05). No adverse drug reactions were seen during the treatment and follow-up period. Conclusions:Intra-articular injection of Triamcinolone acetonide is effective in contro-lling joint symptoms of JIA with less adverse events.
