Objective:To investigate the diagnostic value of serum homocysteine(Hcy),soluble stromelysin 2(sST2)and cystatin C(CysC)for chronic heart failure(CHF).Methods:A total of 86 CHF patients admitted in our hospital were se-lected as CHF group,and 86 healthy individuals who underwent physical examination simultaneously were selected as healthy control group.Serum levels of Hcy,sST2 and CysC,plasma level of N terminal pro brain natriuretic peptide(NT-proBNP)and cardiac function indexes[left atrial diameter(LAD),left ventricular end diastolic diameter(LVEDd),left ventricular ejection fraction(LVEF)]were measured between two groups.Pearson correlation analysis was used to analyze the correlation among serum Hcy,sST2,CysC,plasma NT-proBNP and cardiac function indexes.Receiver operating characteristic curve(ROC)was drawn to evaluate the diagnostic value of serum Hcy,sST2 and CysC and their combined detection for CHF.Results:Compared with healthy control group,there were significant rise in scrum levels of Hcy,sST2 and CysC,plasma NT-proBNP level,LAD and LVEDd,and significant reduction in LVEF in CHF group,P=0.001 all.Pearson correlation analysis indicated that serum Hcy,sST2 and CysC levels were significant positively correlated with plas-ma NT-proBNP level,LAD and LVEDd(r=0.385～0.511,P＜0.05 or＜0.01),and significant inversely correlated with LVEF(r=-0.424～-0.402,P＜0.05 all).AUC of single detection of serum Hcy,sST2 and CysC diagnosing CHF was 0.624,0.720 and 0.870 respectively,and AUC of their combination was 0.865,which was significantly higher than any single detection,P＜0.05 or＜0.01.Conclusion:Serum levels of Hcy,sST2 and CysC abnormally increase in CHF patients,which can be used as auxiliary diagnostic indexes for CHF.The triple combined detection is of great signifi-cance for the diagnosis of CHF.

Objective:To investigate the safety and efficacy of mitoxantrone liposome in the treatment of children with high-risk acute myeloid leukemia(AML).Methods:The children with high-risk AML who received the mitoxantrone liposome regimen at Wuhan Children's Hospital from January 2022 to February 2023 were collected as the observation group,and the children with high-risk AML who received idarubicin regimen were enrolled as controls,and their clinical data were analyzed.Time to bone marrow recovery,the complete remission rate of bone marrow cytology,the clearance rate of minimal residual disease,and treatment-related adverse reactions were compared between the two groups.Results:The patients treated with mitoxantrone liposome showed shorter time to recovery of leukocytes(17 vs 21 day),granulocytes(18 vs 24 day),platelets(17 vs 24 day),and hemoglobin(20 vs 26 day)compared with those treated with idarubicin,there were statistical differences(P＜0.05).The effective rate and MRD turning negative rate in the observation group were 90.9％and 72.7％,respectively,while those in the control group were 94.1％and 76.4％,with no statistical difference(P＞0.05).The overall response rate of the two groups of patients was similar.Conclusion:The efficacy of mitoxantrone liposome is not inferior to that of idarubicin in children with high-risk AML,but mitoxantrone liposome allows a significantly shorter duration of bone marrow suppression and the safety is better.

Objective:To summarize the clinical features of reversible posterior encephalopathy syndrome(PRES)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:The clinical data of six children who developed PRES after undergoing allo-HSCT in the Department of Hematology of Wuhan Children's Hospital from June 2016 to December 2022 were retrospectively analyzed,and their clinical characteristics,imaging examination,laboratory examination,and treatment regression were summarized.Results:Among 281 children underwent allo-HSCT,6 cases(2.14％)developed PRES,with a median age of 5.1(1.5-9.7)years old.4 cases underwent related haploidentical donor transplantation,and 2 cases underwent sibling allografting and unrelated donor allografting donor transplantation,respectively.All six children had an acute onset of illness,with clinical manifestations of nausea and vomiting,seizures,psychiatric disorders,visual disturbances.The five cases elevated blood pressure.All children with PRES were treated with oral immunosuppressive drugs during seizures,and 3 cases were combined with different degrees of graft-versus-host disease.Most of the children showed effective improvement in clinical symptoms and imaging after adjusting/discontinuing suspected medications(cyclosporine,etc.)and symptomatic supportive treatments(oral antihypertensive,diazepam for antispasmodic,mannitol to lower cranial blood pressure),and one of them relapsed more than 8 months after the first seizure.Conclusion:PRES is rare after hematopoietic stem cell transplantation in children,and its onset may be related to hypertension,cytotoxic drugs,graft-versus-host disease,etc.Most of them can be recovered after active treatment,but not completely reversible,and the prognosis of those who combined with TMA is poor.

OBJECTIVES: To compare the efficacy of needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training in the treatment of post-stroke cognitive impairment (PSCI). METHODS: A total of 206 patients with PSCI were randomized into a needle retaining group (103 cases, 9 cases dropped out) and an electroacupuncture group (103 cases, 6 cases dropped out). In addition to the conventional basic medical treatment and the rehabilitation treatment, in the needle retaining group, electroacupuncture at Shenting (GV 24) and Baihui (GV 20) was applied, with continuous wave of 50 Hz in the first 15 min and with disperse-dense wave of 2 Hz/50 Hz in the last 15 min, the needles were continuously retained for 1 h after electroacupuncture, during which cognitive training was adopted; in the electroacupuncture group, cognitive training was performed after the same electric stimulation exerted for 30 min, without additional needles retaining. The treatment was given once a day, 5 times a week for totally 8 weeks in the two groups. Before and after 8-week treatment, the TCM syndrome score was observed; before and after 4,8-week treatment, the scores of mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and ability of daily living were observed in the two groups. The clinical efficacy of the two groups was evaluated after 8-week treatment. RESULTS: After 8-week treatment, the TCM syndrome scores were increased compared with those before treatment in both groups (P<0.05); the TCM syndrome score in the needle retaining group was higher than that in the electroacupuncture group (P<0.05).After 4,8-week treatment, the scores of MMSE, MoCA and ability of daily living were increased compared with those before treatment in both groups (P<0.05); MMSE, MoCA scores after 4,8-week treatment and ability of daily living score after 8-week treatment in the needle retaining group were higher than those in the electroacupuncture group (P<0.05). The total effective rate was 90.4% (85/94) in the needle retaining group, which was superior to 82.5% (80/97) in the electroacupuncture group (P<0.05). CONCLUSIONS Both needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training can effectively treat PSCI, improve the clinical symptom, cognitive function and ability of daily living in PSCI patients. Needle retaining after electroacupuncture combined with cognitive training has a better therapeutic effect.

OBJECTIVE: To analyze the clinical phenotype and genetic variant in a child with Raynaud-Claes syndrome (RCS). METHODS: A child who was diagnosed with RCS at the Children's Hospital Affiliated to Zhengzhou University for delayed language and motor development in August 2022 was selected as the study subject. Clinical data of the child were collected, and potential genetic variant was detected by next-generation sequencing and Sanger sequencing. The pathogenicity of the candidate variant was analyzed. RESULTS: The child, a 4-year-and-4-month-old male, has manifested global developmental delay, speech disorders, special facial features and behavioral abnormalities. Genetic testing revealed that he has harbored a hemizygous c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene, which was not detected in either of his parents. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PVS1+PS2+PM2_Supporting). CONCLUSION The c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene probably underlay the PCS in this child. Above finding has expanded the mutational spectrum of the CLCN4 gene and enabled genetic counseling and prenatal diagnosis for his family.

Rheumatoid arthritis (RA) is an autoimmune disease driven by antigens and mediated by T cells. Collagen II (CII) and fibrinogen (Fib) are the two main antigens in the pathogenesis of RA. The antigen produced after citrulline modification (Cit) is also one of the inducements to induce the body to produce a pathogenic anti-citrulline protein antibody (ACPA). To provide a reference for RA-related research, this study intends to establish an RA animal model by using CII, Cit-CII, Fib, and Cit-Fib antigens, emulsification with complete Freund's adjuvant and immunization with DBA/1 mice, respectively, to compare the pathological characteristics of RA models induced by different antigens from the aspects of pathology, imaging and serum biochemistry. Animal welfare and experimental process are in accordance with the regulations of the Experimental Animal Ethics Committee of the China Academy of Chinese Medical Sciences. The results showed that the CII, Cit-CII, and Cit-Fib induced mice all had symptoms such as joint redness and swelling, and toe deformation and the clinical score and incidence rate were higher than those of the normal group. The CII group had the most serious lesions, with a incidence rate of 100%, and the Cit-CII and Cit-Fib groups had mild symptoms, with a incidence rate of 25% and 37.5%, respectively; pathological and imaging examination results showed that the joints of mice in CII-induced group showed severe synovial inflammation, cartilage and bone destruction, while those in Cit-CII and Cit-Fib group showed only slight inflammatory infiltration, joint cavity stenosis and bone destruction; the results of serum antibody detection showed that CII, Cit-CII and Cit-Fib groups all produced high levels of anti-cyclic citrullinated peptide (CCP) antibodies, among which, Cit-Fib group > Cit-CII group > CII group > Fib group, and both Cit-CII and Cit-Fib groups produced high levels of citrullinated epitope-specific antibodies, while the total IgG level was the highest in CII group; serum ELISA and RT-PCR analysis of joint tissue showed that the expression of pro-inflammatory factors and bone destruction-related molecules increased most significantly in the CII-induced group, followed by Cit-Fib and Cit-CII. The above results showed that among the four different antigens, the symptoms and conditions of arthritis in RA mice induced by CII were the most serious, and IgG instead of anti-CCP antibody was its typical immunological feature, and CII could be the first choice for the model of RA mice; Cit-Fib has certain immunogenicity, can partially induce the symptoms and conditions of RA arthritis in mice, and produce high-level anti-CCP antibody and anti-Cit-Fib antibody, which is more suitable for the study of citrulline-related RA; although Cit-CII has certain immunogenicity, the incidence, and severity of RA arthritis induced by Cit-CII in mice are low.

Objective: To explore the epidemiological characteristic of a COVID-19 outbreak caused by 2019-nCoV Omicron variant BF.7 and other provinces imported in Shenzhen and analyze transmission chains and characteristics. Methods: Field epidemiological survey was conducted to identify the transmission chain, analyze the generation relationship among the cases. The 2019-nCoV nucleic acid positive samples were used for gene sequencing. Results: From 8 to 23 October, 2022, a total of 196 cases of COVID-19 were reported in Shenzhen, all the cases had epidemiological links. In the cases, 100 were men and 96 were women, with a median of age, M (Q₁, Q₃) was 33(25, 46) years. The outbreak was caused by traverlers initial cases infected with 2019-nCoV who returned to Shenzhen after traveling outside of Guangdong Province.There were four transmission chains, including the transmission in place of residence and neighbourhood, affecting 8 persons, transmission in social activity in the evening on 7 October, affecting 65 persons, transmission in work place on 8 October, affecting 48 persons, and transmission in a building near the work place, affecting 74 persons. The median of the incubation period of the infection, M (Q₁, Q₃) was 1.44 (1.11, 2.17) days. The incubation period of indoor exposure less than that of the outdoor exposure, M (Q₁, Q₃) was 1.38 (1.06, 1.84) and 1.95 (1.22, 2.99) days, respcetively (Wald χ²=10.27, P=0.001). With the increase of case generation, the number and probability of gene mutation increased. In the same transmission chain, the proportion of having 1-3 mutation sites was high in the cases in the first generation. Conclusions: The transmission chains were clear in this epidemic. The incubation period of Omicron variant BF.7 infection was shorter, the transmission speed was faster, and the gene mutation rate was higher. It is necessary to conduct prompt response and strict disease control when epidemic occurs.

Objective: To investigate the clinical, radiological, histological and molecular features and the differential diagnosis of fibrocartilaginous mesenchymoma (FM). Methods: Four cases of FM diagnosed in the Department of Pathology, the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from 2020 to 2022 were analyzed. Related literature was also reviewed. Results: Case 1 was a 10-year-old girl with bone destruction in the sacrum and L5 articular processes revealed by CT scan. Case 2 was a 7-year-old girl with an aggressive lesion in her right distal ulna. Case 3 was an 11-year-old boy with a lesion in the metaphysis of his left proximal tibia. Case 4 was an 11-year-old boy with bone destruction in the distal portion of a radius. Microscopically, the four tumors all consisted of numerous spindle cells, hyaline cartilage nodules, and bone trabeculae. The hypocellular to moderately cellular spindle cell component contained elongated cells with slightly hyperchromatic, mildly atypical nuclei arranged in bundles or intersecting fascicles. Benign-appearing cartilaginous nodules of various sizes and shapes were scattered throughout the tumors. There were areas mimicking epiphyseal growth-plate characterized by chondrocytes arranged in parallel columns and areas of enchondral ossification. The stroma was rich in mucus in case 1. Mutation of GNAS and IDH1/IDH2 and amplification of MDM2 gene were not found in any of the three tested cases. Conclusions: FM is very rare and tends to affect young patients. It most frequently occurs in the metaphysis of long tubular bones, followed by the iliac-pubic bones and vertebrae. FM is characterized by a mixed population of spindle cells, hyaline cartilage nodules and trabeculae of bone, without specific immunophenotypes and molecular alternations. As a borderline, locally aggressive neoplasm, surgical removal with a wide margin is generally the treatment of choice for FM.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
