Objective:To investigate the effects of Hydroxychloroquine on cell apoptosis in peripheral blood mononuclear cells of systemic lupus erythematosus and its mechanisms.Methods:The peripheral blood mononuclear cells of 30 active SLE patients and 15 healthy persons were separated for cell culture.There were four groups:control group,SLE group and HCQ 5 mg/L and HCQ 25 mg/L group.MTT was used to measure the inhibitory effect.Annexin V/PI flow cytometry was performed to analyze cell apoptosis.Western blot was used to evaluate the expressions of PI3 K,pAKt,mTOR,BCL-2,BAX and caspase-3.Besides,the PBMCs of SLE patients were treated with HCQ 25 mg/L and the PI3K/Akt pathway inhibitor LY294002 20 μmol/L and its cell growth inhibition and apoptosis were observed.Results:Compared with the control group,the cell growth inhibition and apoptosis rate of SLE patients group were significantly increased(P＜0.05);while the cell growth inhibition and apoptosis rate of HCQ 5 mg/L and 25 mg/L were increased significantly than the SLE patients group(P＜0.05).Compared with SLE patients group,the expression levels of PI3K,pAKt,mTOR and BCL-2 of HCQ group were significantly increased while the expression of BAX and caspase-3 decreased significantly (P＜ 0.05).The PI3K/Akt pathway inhibitor LY294002 could block the PBMCs apoptosis of SLE patients.Conclusion:Hydroxychloroquine can promote the PBMCs apoptosis of SLE patients by PI3K/Akt signaling pathways.

OBJECTIVETo study the effect of B lymphocyte-induced mature protein-1(Blimp1) expression in bone marrow mononuclear cells on the prognosis of patients with multiple myeloma.

METHODSForty-eight patients with multiple myeloma from January 2014 to January 2015 were selected. The expression of Blimp1 in the bone marrow of all the patients was measured. According to the median score of Blimp1 expression level, the patients was divided into low expression group (L group, 22 cases) and high expression group (H group, 26 cases). The related influencing factors of different Blimp1 expression levels, the clinical efficacy, immunophenotypic changes and progression-free survival(PFS) were compared between different Blimp1 expression groups.

RESULTSThere were no significant differences in sex, age, type, stage and treatment stage between the 2 groups (P> 0.05). The total remission rate of the low expression group was significantly higher than that in the high expression group (P<0.05). However before treatment, there was no significant difference in the positive rate of CD19, CD38, CD56, CD138 and minimal lesion between the 2 groups (P> 0.05); after treatment the positive expression rates of CD38, CD56, CD138 and minimal lesion in the low expression group were significantly lower than those in the high expression group. While the positive expression rate of CD19 was significantly higher than that in high expression group (P<0.05). The PFS of 1, 2 and 3 years in the low expression group was significantly higher than that in the high expression group (P<0.05).

CONCLUSIONThe MM patients with the high in staging and the larger in diffeculty of treatment possess high Blimp1 expression, however, the therapeutic efficacy and prognosis of MM patients with low Blimp1 expression are significantly better than those of MM patients with high Blimp1 expression.

OBJECTIVE: To observe the expression of plasma microRNA (miR)-146a and miR-223 in children with acute lymphoblastic leukemia (ALL), so as to analyze the relationship between the two factors and the prognosis of children with ALL. METHODS: 100 children with ALL treated in the hospital from January 2015 to December 2017 were selected, according to the standard of Chinese Children's Leukemia Group (CCLG)-ALL-2008 program, the children were performed standardized treatment in our hospital according to different risk degree, the follow-up results were obtained, the follow-up time was ≥36 months, and the follow-up time was till to March 2021, the recurrence and mortality of the children were used as prognostic indicators; the baseline data of the children at admission were inquired and recorded, the plasma miR-146a and miR-223 levels were analyzed at admission, and their correlation with the prognosis of children with ALL was analyzed. RESULTS: During the follow-up period, 4 cases of children died while 18 cases recurred, which means 22(22.00%) children showed the poor prognosis; the plasma miR-146a level of the children in poor prognosis group at admission was higher than those in good prognosis group, while the plasma miR-223 level was lower than those in good prognosis group, the differences showed statistically significantly (P<0.05); the results of regression analysis showed that the over expression of plasma miR-146a and low expression of plasma miR-223 at admission might be associated with poor prognosis in ALL children, and might be a risk factor for poor prognosis in children (P<0.05); the ROC curve showed that the AUC of plasma miR-146a and miR-223 at admission alone or in combination showed the predictive value for the risk of poor prognosis in children with ALL(AUC >0.80); the results of correlation test showed that there was a negative correlation of plasma miR-146a with miR-223 levels at admission (r=-0.239, P=0.016). CONCLUSION Plasma miR-146a is overexpressed and miR-223 is low-expressed in children with ALL, the abnormal expression of the two factors is related to the prognosis of children with ALL.

OBJECTIVETo investigate the antitumor effect of arsenic trioxide (ATO) combined with itraconazole (ITRA) on human multiple myeloma NCI-H929 cells by synergistically inhibiting Hedgehog (HH) signaling pathway.

METHODSThe inhibitory rate of NCI-H929 cells was assayed by MTT method. Tumor weight, tumor weight inhibition rate, and tumor volume of mouse model with multiple myeloma were examined. The ELISA were appled to detect the M-protein, qPCR and Western blot were used respectively to detect the expression level of Ptch, SMO, Gli and downstream target genes, the survival rate of tumor-bearing mice was analyzed.

RESULTSATO combined with ITRA significantly inhibited NCI-H929 cell proliferation as compared with a single administration. The combination of ATO and ITRA could synergistically inhibit tumor growth and obviously reduced tumor burden, survival time of tumor-bearing mice was significantly prolonged. qPCR and Western blot results confirmed that the ATO combined with ITRA could significantly down-regulated expression of Gli1, leading to significantly decrease of cyclinD1 and BCL-2 expression levels.

CONCLUSIONATO combined with ITRA can more strongly suppress the growth of multiple myeloma NCI-H929 cells, as compared with a single administration. The synergistic effect of ATO and ITRA significantly down-regulates expression of Gli1 in HH signaling pathway, moreover the inhibition of target gene overexpression may be one of two drug mechanisms.

Objective To use World Health Organization Family International Classifications (WHO-FICs) to explore the framework and approaches of development and research of guidelines of rehabilitation at levels of policies, community and services.Methods The important documents and tools of rehabilitation at international level, including United Nations Convention on the Rights of Persons with Disabilities, WHO World Report on Disability, Community-based Rehabilitation Guideline, Rehabilitation in Health Service System, and International Classification of Diseases (ICD), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHI) of WHO-FICs, had been discussed.Results The framework, classifications, diagnosis and description of diseases and functioning, coding, intervention and functioning evaluation based on ICD-11, ICF and ICHI-β-2 had been established for development and implementation of rehabilitation guidelines and Cochrane rehabilitation.Conclusion The framework and systematic approaches of ontology, classification, terminology, coding, diagnosis and description of diseases and functioning, interventions and evaluations for the development and implementation of rehabilitation guidelines had been developed.

Objective:To explore systematic implementation of World Health Organization Family International Classifications (WHO-FICs) in the field of rehabilitation: the theoretical and policy framework at macro level, governance and management mechanism at meso level, and implementation modules at micro levels, respectively. Methods:The policy and theoretical framework of rehabilitation development was discussed based on the international rehabilitation policy documents of WHO, mainly as World Report on Disability, Global Action Plan on Disability and Rehabilitation in Health Service System. Protocol and roadmap of systematic implementation of WHO-FICs, including International Classification of Diseases (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHIβ-2) was proposed. Results:With the use of WHO-FICs, the theoretical and policy framework of rehabilitation was constructed, and the contents and principles of modern rehabilitation services were clarified at macro-level. Rehabilitation is an important part of health service, there are six building blocks: i.e. leadership and governance, financing, human resources for health, service providing, medical technology and health information system. It proposed to use knowledge management system of WHO-FICs, including the classification, nomenclature, definitions, descriptions, terminology and coding systems, to standardize rehabilitation evaluation and statistics. The management and governance system of rehabilitation should be implemented using WHO-FICs. Rehabilitation services are based on the bio-psycho-social model and implemented the principles of people-centered and functioning-oriented. The systematic implementation of WHO-FICs in rehabilitation abide by the model of "Evaluation (ICHI)－Evaluation, Description, Classification and Coding of Functioning (ICF)－Disease Classification, Diagnosis and Coding (ICD)－Rehabilitation Intervention (ICHI)", and with the standardized process of "Evaluation (Functioning and unmet needs)－Diagnose (Disease and Functioning)－Planning of Rehabilitation－Intervention－Evaluation of Outcome". The mic-modules of implementation of WHO-FICs in rehabilitation had been constructed. There were 28 categories of diseases, 7 categories of functioning and 6 categories of rehabilitation interventions in rehabilitation proposed by International Society of Physical and Rehabilitation Medicine. According to ICD-11 and ICF, it proposed to use WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), Brief Model Disability Survey (MDS-B) and VB40 Generic Functioning Domains (VB40), and the ICF core-sets in evaluation of functioning and rehabilitation outcome. The implementation of WHO-FICs in management of medical records and reporting realized the standardized management of medical record, encoding of diseases, functioning and intervention, reporting of performance, and provided tools for billing, reimbursement and payment management of rehabilitation. It proposed to develop WHO-FICs based clinical data sets and big data to implement functioning-related Diagnosis Related Groups and case-mix statistics. Conclusion:With the systematic implementation of WHO-FICs in rehabilitation, the policy and theoretical framework at macro level had been developed. The mechanism of management and governance at meso level had been explored. The application modules and approaches at micro level had been established. A scientific and effective overall solution had been proposed to enhance the scientific, standardized, refined and informatization level, strengthen the level and governance capacity, and improve the quality, safety and the coverage of rehabilitation services.
