Objective To investigate the clinical features of myelin oligodendrocyte glycoprotein-IgG-associated disorders （MOGAD）. Methods A retrospective analysis was performed for the clinical data of nine patients with MOGAD who were admitted to our department. Results Among the nine patients with MOGAD， there were five male patients and four female patients， with a median age of onset of 29.0 years. The main clinical symptoms included optic neuritis in five patients， cerebral symptoms （including mental symptoms）in five patients，seizures in four patients， brainstem symptoms in three patients， pyramidal signs in three patients， cerebellar symptoms in three patients， rectal and bladder dysfunction in three patients， myelitis in two patients， paresthesia in two patients， and comorbidity with autoimmune encephalitis in one patient. All patients tested positive for serum MOG-IgG， and two patients tested positive for MOG-IgG in cerebrospinal fluid. MRI showed that cerebral lesions mainly involved the midline structure and deep gray matter，and there were four patients（44.4%） with lesions in the midbrain， the pons， and the medulla oblongata and four patients （44.4%）with lesions in the fourth ventricle； spinal lesions often involved long segments （≥3 segments）， and there were two patients with lesions in cervical spinal cord and one patient with lesions in the thoracic spinal cord. All nine patients received immunotherapy in the acute stage， with a mean Expanded Disability Status Scale score of （3.94±2.28） for neurological function assessment. Three patients experienced recurrence during the median follow-up time of 36.0 months，among whom two patients had myelitis. Conclusion There was no significant sex difference in the prevalence rate of MOGAD，and the age of onset of MOGAD is earlier than that of multiple sclerosis and neuromyelitis optica spectrum disorder.Optic neuritis is the most important clinical phenotype of MOGAD， and MOGAD patients with myelitis phenotype all have longitudinal long-segment lesions of the spinal cord. The different clinical phenotypes of MOGAD may be associated with recurrence rate.

Objective To develop an evaluation system for quality palliative care and provide an evaluation tool for quality palliative care service.Methods A preliminary evaluation system was drafted by using literature review and group discussion,aligning with the U.S.National Consensus Project for Quality Palliative Care(NCP).The system was revised and refined by two rounds of Delphi consultation with 15 palliative care experts(including specialists in clinical practice,nursing management,nursing research and education)from Tier-IIIA hospitals in Guangdong Province.Indicator weights were determined via consensus.Results Both rounds of expert consultation achieved 100.00%response rates.Expert authority coefficient(Cr)was 0.855.The importance scores of the level-1,level-2 and level-3 indicators of the second round of expert consultation were 4.90-5.00,4.80-5.00 and 4.37-5.00,respectively.Coefficients of variation were 0-0.06,0-0.1 and 0-0.19,respectively.The full score ratio ranged between 0.93 and 1.00,0.8 and 1.00,and 0.67 and 1.00.Kendall's W coefficients were 0.214,0.287 and 0.245,respectively(all P<0.01).The nine level-1 indicators were identified as care structure and process,physiological care,psychological care,social care,mental care,cultural care,end-of-life care,ethical care and quality improvement,with the weight coefficients of 0.123,0.153,0.110,0.106,0.098,0.082,0.119,0.092 and 0.117,respectively.The final evaluation system for quality palliative care included 9 indicators in level-1,22 in level-2 and 69 in level-3.Conclusion The evaluation system for quality palliative care developed on the basis of NCP is scientifically innovative and valid in content.Further studies are required to evaluate its validity..

Epilepsy is one of the common diseases of the nervous system,which is characterized by repeated epilep-tic seizures caused by abnormal discharge of brain neurons.Brivaracetam is an analogue of the third-generation antiepilep-tic drug levetiracetam and exerts a therapeutic effect by binding to synaptic vesicular protein 2A.This article reviews the disease of epilepsy and the mechanism of action,pharmacokinetic characteristics,clinical efficacy,safety,and adverse reactions of brivaracetam in epilepsy,in order to provide a better choice of drugs for the treatment of epilepsy.

OBJECTIVE To explore the way to re-use epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKI） in patients with EGFR-TKI-induced interstitial pneumonia （IP）， using osimertinib as an example. METHODS The IP treatment regimen and re-use of EGFR-TKI regimen in a patient who developed IP after the use of osimertinib were analyzed. And a literature review was made by combining the characteristics of the cases which reported in the literature and the characteristics of this case. RESULTS The patient’s IP symptoms due to treatment with osimertinib had resolved after treatment. The patient’s IP symptoms also did not worsen after using almonertinib in combination with hormones as re-use of EGFR-TKI regimen. However， almonertinib was discontinued as the patient experienced disease progression. The adverse reactions of IP needed to be dealt with in time， the EGFR-TKI should be discontinued and symptomatic treatment should be given. CONCLUSIONS EGFR-TKI targeted therapy could be re-selected by replacing EGFR-TKI， adjusting the dose of EGFR-TKI， and using hormones in combination. EGFR-TKI-induced adverse drug reactions of IP are rare， but need to be observed closely. If other EGFR-TKI is used， close monitoring of adverse reactions and curative effects are also required in order to adjust the patient’s treatment plan in time.

【Objective】 To analyze the distribution of unexpected antibodies in tumor patients retrospectively and explore the clinical significance. 【Methods】 Unexpected antibody screening was performed on inpatients with blood preparation and blood transfusion in our hospital from January 2004 to December 2022, with 1 176 cases tested positive, and the types of unexpected antibodies and distribution characteristics were statistically analyzed. 【Results】 Unexpected antibodies were screened in 1 176 cases, with the positive rate at 1.05% (1 176/111 483). The unexpected antibodies were mainly anti-E 16.33%(192/1 176), anti-M 7.99% (94/1 176), anti-Mur 5.70% (67/1 176) and anti-Le^a 4.76% (56/1 176). Among the 1 176 cases, gastrointestinal tumors accounted for 27.99% (329/1 176), gynecological tumors accounted for 24.84% (292/1 176), respiratory tumors accounted for 16.67% (196/1 176) . 【Conclusion】 The influencing factors of unexpected antibodies in tumor patients were disease type, blood transfusion history and blood type. Therefore, it is necessary for clinical departments to carry out unexpected antibody screening and perform Rh blood type matched transfusion for tumor patients to avoid alloantibody production.

Objective:To investigate the effect of horticultural therapy on social function of elderly inpatients with cognitive dysfunction.Methods:Ninety inpatients with cognitive dysfunction who met the diagnostic criteria of ICD-10 were randomly divided into horticultural research group and control group, with 45 patients in each group.Finally, totally 82 completed the test with 41 in each group.Patients in the two groups were both given drug therapy according to clinical symptoms.At the same time, patients in the research group were given horticultural therapy 3 times a week, 90 minutes each section, for 12 weeks.Scale of social function in psychosis inpatients(SSPI) was used to assess the social function of the patients in the two groups were at baseline, 4, 8 and 12 weekends of the treatment.SPSS 25.0 software was used to conduct chi-square test and independent sample t-test for demographic data of the two groups, and repeated measures ANOVA was performed for SSPI score. Results:The results of repeated measure analysis of variance showed that the group main effect ( F=7.226, F=13.428, F=24.817, F=19.793) and interaction effect between time and group were all statistically significant ( F=29.644, F=42.937, F=53.246, F=67.215)(all P<0.01) in daily living ability (factor Ⅰ), mobility and interaction (factor Ⅱ), social activity skills score (factor Ⅲ) and total score.Simple effect analysis showed there were no statistically significant differences in each factor score and total score between the two groups at the baseline ( P>0.05), and there were statistically significant differences in each factor scores and total score at the end of the 8th weekend ((9.95±2.41), (10.39±3.38), (6.56±3.24), (26.90±7.88) vs (8.10±2.45), (6.88±3.48), (2.81±2.50), (17.78±6.96))and 12th weekend((10.27±2.16), (11.61±3.07), (7.88±3.08), (29.76±7.40) vs (7.56±2.41), (5.78±3.21), (2.34±2.02), (15.68±6.24)) (all P<0.01). The pair-to-pair comparison within the group showed that the differences in factor Ⅱ, factor Ⅲ and total score of the research group at the end of the 12th weekend ((11.61±3.07), (7.88±3.08), (29.76±7.40)) were higher than those at the baseline((8.59±3.93), (4.56±3.32), (22.02±8.35)), 4th weekend((9.07±4.14), (5.12±3.35), (23.59±8.51)), and 8th weekend((10.39±3.38), (6.56±3.24), (26.90±7.88))(all P<0.05). Factor Ⅰ (10.27±2.16) showed a statistically significant difference compared with the baseline (8.88±2.65) and 4th weekend (9.39±2.63)(both P<0.05). All the scores showed an upward trend. Conclusion:Horticultural therapy can improve the social function of elderly inpatients with cognitive impairment.

Objective:To analyze the clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with NPM1 mutation, and to explore the prognostic factors.Methods:A total of 77 AML patients with NPM1 gene mutation admitted to Hebei Yanda Ludaopei Hospital from May 1st 2012 to December 31st 2021 were enrolled in the study, including 34 male and 43 female patients. The median age was 40 (3, 68) years old. Patients were selected and divided into 4 groups according to the morphological FAB classification. There were 29 cases (37.7%) of M1 type, 13 cases (16.9%) of M2 type, 23 cases (29.9%) of M4 type, and 12 cases (15.5%) of M5 type. The clinical characteristics, bone marrow/peripheral blood cell morphology, immunophenotype, cytogenetics, molecular biology and overall survival of different groups were retrospectively analyzed, and the risk factors affecting the prognosis of AML were also explored. Cox multivariate regression was used to analyze the clinical influencing factors of survival and prognosis.Results:The white blood cell counts were highest in M4 and M5 patients and lowest in M2 patients, while no significant difference in the red blood cell, hemoglobin, and platelet counts( P>0.05). Morphologically, there were significant differences in the percentage of blasts and blasts with cup-like nuclei on bone marrow (BM) and peripheral blood (PB). The proportion of blasts in BM and PB was the highest in M1 and the lowest in M2 ( P<0.001). The positive rate of blasts with cup-like nuclei was the highest in M1 and the lowest in M5 of BM ( P<0.001), while the highest in M2 and the lowest in M5 of PB ( P=0.006). The scores of myeloperoxidase and chloroacetate esterase were all the highest in M1 and the lowest in M5 ( P<0.001, 0.001, respectively). In terms of molecular biology, the occurence rate of blasts combined with DNMT3A mutation was the highest in M4 and the lowest in M2 ( P=0.044), while those combined with FLT3-ITD mutation was the highest in M4 and the lowest in M5 ( P=0.002). In immunophenotype, there were significant differences in the expression positivities of seven antigens including HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO ( P<0.05). Multivariate COX regression analysis showed that no recurrence after treatment ( P<0.001), complete remission after treatment ( P=0.015) and transplantation ( P<0.001) were correlated with overall survival (OS). No recurrence after treatment ( P=0.033), transplantation ( P=0.027), no mutation of FLT3-ITD ( P=0.040), and hemoglobin concentration ( P=0.023) were associated with relapse-free survival (RFS). Survival analysis by Kaplan-Meier curve showed that there was no significant difference in survival time between the M1, M2, M4 and M5 groups in OS and RFS. Conclusion:There were significant differences in the white blood count, the percentage of blasts and blasts with cup-like nuclear morphology, cytochemical staining (MPO integration, CE integration and percentage of NAS-DCE), gene mutation (DNMT3A and FLT3-ITD) and immunophenotypes (HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO) between the four groups. The multivariate analysis revealed that no recurrence after treatment and transplantation were independent prognostic factors in NPM1 mut AML patients. On the other hand, FLT3-ITD mutation and hemoglobin concentration were associated with RFS and complete remission after treatment was associated with OS in the entire NPM1 mut cohort.

Objective:To evaluate the residual risk (RR) of transfusion transmitted HIV (TT-HIV) after the implementation of nucleic acid amplification test (NAT) in blood screening test among blood centers in China.Methods:The data of blood donors and HIV infection markers from 2017 to 2020 were collected from 28 blood centers via the Platform of Comparison of blood establishments Practice in Chinese Mainland. The new infection rate/window period mathematical model was used for two types of blood screening strategies, namely, two rounds ELISA plus individual NAT take turn with pooling NAT (2ELISA+ ID-NAT/MP-NAT) and two ELISA plus one round pooling NAT (2ELISA+ MP-NAT), and the RR of HIV infection was estimated also based on first donors (FDs) and repeated donors (RDs) in different blood donation years. T-test analyses were conducted for comparing TT HIV RR among FDs and RDs in different blood donation years with two blood screening strategies, and the variation trend of RR in HIV test was observed.Results:From 2017 to 2020, the RR of FDs in 2ELISA+ ID-NAT/MP-NAT blood screening strategy was 2.869/10 6 person-year, 3.795/10 6 persons-year, 3.879/10 6 person-year, and 2.890/10 6 person-year respectively. The RR of RDs was 1.797/10 6 person-year, 1.502/10 6 person-year, 1.857/10 6 person-year, and 1.483/10 6 person-year respectively. Significant difference exists between RR of FDs and RDs, with F=9.898 and p<0.05. In 2ELISA+ MP-NAT strategy, the RR of FDs was 3.508/10 6 person-year, 1.868/10 6 person-year, 2.204/10 6 person-year, and 1.765/10 6 person-year respectively. The RR of RDs was 0.948/10 6 person-year, 0.926/10 6 person-year, 0.748/10 6 person-year, and 0.682/10 6 person-year respectively. Statistical difference existed between RR of FDs and RDs, with F=17.126 and P<0.05. There was no significant difference between the RR of FDs in these two strategies with F=3.493 and P>0.05, while there was a difference between the RR of RDs in these two strategies with F=24.516 and P<0.05, and a difference between the RR of total donors (TDs) in these two strategies F=20.216 and P<0.05. Conclusions:The RR of TT HIV significantly decreased after the introduction of NAT into blood test among blood centers in China. There were some differences in the RR of HIV testing among different blood screening strategies. There could be significant differences in the RR of HIV testing among different groups of blood donors. Compared with FDs, RDs is the low risk group for HIV.

Ten novel podophyllotoxin derivatives (IIIa-IIIi and IV) were synthesized by three-step reactions using podophyllotoxin and N-benzyloxycarbonyl glycine-L-proline as raw material. The structures of the target compounds were confirmed by 1H NMR, 13C NMR and MS. MTT method was used to test anti-tumor activity of the target compounds on HepG2, THP-1, HeLa and MCF-7 cells. The results showed that all the target compounds had inhibitory activity against HepG2, THP-1, HeLa and MCF-7 cells, and the inhibitory activity of IIIa on HepG2 cells was the most prominent with an IC50 value of 0.58 nmol/L. The binding mode of compound IIIa and FAPα was studied by molecular docking. Compound IIIa could bind to multiple sites of FAPα enzyme.
