Objective To understand the disease acceptance status and related factors in human immunodeficiency virus(HIV)-infected/acquired immunodeficiency syndrom(AIDS)patients,so as to guide the clinical development of intervention measures,and to provide empirical evidence for improving clinical outcomes.Methods Convenience sampling method was used to select 555 HIV-infected/AIDS patients who received treatment in the designated AIDS treatment clinic of a hospital.General data,disease acceptance,disease self-management efficacy and clinical out-comes(such as quality of life,CD4+T lymphocyte count and HIV viral load)of the studied subjects were collected.Results The average disease acceptance of HIV-infected/AIDS patients was(26.08±5.34)points.Multiple linear regression analysis showed that religious belief and self-management efficacy were related factors affecting the di-sease acceptance of patients(both P＜0.05),which could explain the 30.4％variation in disease acceptance of HIV-infected/AIDS patients,and the disease acceptance of patients was closely related to their quality of life(P＜0.001).Conclusion HIV-infected/AIDS patients have a moderate level of disease acceptance.Medical staff should fully consider patients'religious beliefs and self-management efficacy,so as to formulate targeted intervention mea-sures to improve patients'acceptance of disease,and further promote patients'quality of life.

Aim To investigate the antibacterial activity and anti-resistant mutation ability of Qiguiyin decoction (a traditional Chinese herbal formula) combined with levofloxacin against pseudomonas aeruginosa byantibacterial experiment in vitro and serum pharmacology. Methods The minimal inhibitory concentrations (MICs) of levofloxacin and Qiguiyin decoction were detected respectively by the broth dilution technique.The MIC of the combination of two drugs was determined by the micro chessboard dilution method. The effects of combined drugs on enhancing the antibacterial activity of different strains were evaluated respectively by calculating the fractional inhibitory concentration index (FICI). The drug-containing serum of levofloxa-cin group, Qiguiyin decoction group, Qiguiyin decoction combined with levofloxacin group and control group was prepared. The antibacterial rate, MIC and MBC of 10% ~ 90% serum against the two strains were determined. Results Combined with Qiguiyin decoction, MIC of levofloxacin against pseudomonas aeruginosa (standard/resistant) decreased significantly, 0. 5 < FICI ^ 1. With the increase of the proportion of serum, the inhibitory rate of 10% ~ 90% drug-containing serum to pseudomonas aeruginosa (standard/resistant) increased gradually.compared with the control group, the inhibitory effect of the Qiguiyin group on bacteria was significantly enhanced. The MIC

This study aims to separate and characterize self-assembled nanoparticles(SAN) from Shaoyao Gancao Decoction(SGD) and determine the content of active compounds. Further, we aimed to observe the therapeutic effect of SGD-SAN on imiquimod-induced psoriasis in mice. The separation of SGD was performed by dialysis, and the separation process was optimized by single factor experiment. The SGD-SAN isolated under the optimal process was characterized, and the content of gallic acid, albiflorin, paeoniflorin, liquiritin, isoliquiritin apioside, isoliquiritin, and glycyrrhizic acid in each part of SGD was determined by HPLC. In the animal experiment, mice were assigned into a normal group, a model group, a methotrexate group(0.001 g·kg~(-1)), and SGD, SGD sediment, SGD dialysate, and SGD-SAN groups of different doses(1, 2, and 4 g·kg~(-1)) respectively. The psoriasis grade of mice was evaluated based on the pathological changes of skin lesions, the content of inflammatory cytokines, organ index and other indicators. The results showed that SAN obtained by centrifugation at 13 000 r·min~(-1) for 30 min was stable after dialysis for 4 times, which were uniform spherical nanoparticles with the particle size of(164.43±1.34) nm, the polydispersity index of(0.28±0.05), and the Zeta potential of(-12.35±0.80) mV. The active compound content accounted for more than 70% of SGD. Compared with the model group, SAN and SGD decreased the skin lesion score, spleen index, and inflammatory cytokine levels(P<0.05 or P<0.01) and alleviated the skin thickening and infiltration of inflammatory cells. However, the sediment group and the dialysate group had no obvious effect. SGD showed a good therapeutic effect on imiquimod-induced psoriasis in mice, and SAN demonstrated the effect equivalent to SGD in a dose-dependent manner. Therefore, we conclude that the SAN formed during decocting is the main active form of SGD, which can lower the levels of inflammatory cytokines, promote the normal differentiation of keratinocytes, and reduce the infiltration of inflammatory cells in the treatment of psoriasis lesions in mice.

OBJECTIVES: To explore the potential biomarkers for the diagnosis of primary brain stem injury (PBSI) by using metabonomics method to observe the changes of metabolites in rats with PBSI caused death. METHODS: PBSI, non-brain stem brain injury and decapitation rat models were established, and metabolic maps of brain stem were obtained by LC-MS metabonomics method and annotated to the HMDB database. Partial least square-discriminant analysis (PLS-DA) and random forest methods were used to screen potential biomarkers associated with PBSI diagnosis. RESULTS: Eighty-six potential metabolic markers associated with PBSI were screened by PLS-DA. They were modeled and predicted by random forest algorithm with an accuracy rate of 83.3%. The 818 metabolic markers annotated to HMDB database were used for random forest modeling and prediction, and the accuracy rate was 88.9%. According to the importance in the identification of cause of death, the most important metabolic markers that were significantly up-regulated in PBSI group were HMDB0038126 (genipinic acid, GA), HMDB0013272 (N-lauroylglycine), HMDB0005199 [(R)-salsolinol] and HMDB0013645 (N,N-dimethylsphingosine). CONCLUSIONS GA, N-lauroylglycine, (R)-salsolinol and N,N-dimethylsphingosine are expected to be important metabolite indicators in the diagnosis of PBSI caused death, thus providing clues for forensic medicine practice.

AIM:To identify the reasons for not improving visual acuity of patients with diabetic macular edema(DME)and its correlation with optical coherent tomography(OCT)imaging characteristics. They were treated with anti-vascular endothelial growth factor(VEGF)again after an interruption of treatment due to the COVID-19 pandemic.METHODS: Retrospective cases study. A total of 31 patients(40 eyes)with DME and treated with anti-VEGF drugs in the Department of Ophthalmology of the First Affiliated Hospital of Xi'an Jiaotong University between December 2019 and July 2020 were selected. All patients had an treatment history of interruption due to COVID-19. Based on the behavioral standard of best corrected visual acuity(BCVA)at 1mo after re-treatment, they were divided into improved visual acuity group(14 eyes)and non-improved visual acuity group(26 eyes). All patients received comprehensive ophthalmic examinations, including BCVA, intraocular pressure, OCT, fundus photography, and fundus fluorescein angiography(FFA). The central retinal thickness(CRT), hyper-reflective retinal dots(HRD), subretinal fluid(SRF), intraretinal fluid(IRF), disorganization of the inner retinal layers(DRIL)and ellipsoid zone disruption(EZD)were quantified by Image J. The correlation between BCVA and CRT, the number of HRD, the diameter of SRF and IRF, and the height of DRIL and EDZ width at 1mo after treatment were analyzed by Spearman correlation.RESULTS: The proportion of HRD in OCT was significantly higher in the non-improved visual acuity group than that in the improved visual acuity group(χ2=5.43, P=0.0072); There was a positive correlation between the difference of BCVA(LogMAR)and CRT change in DME patients after treatment(rs=0.406, P=0.009); There was a positive correlation between BCVA(LogMAR)and EZD width after treatment(rs=0.358, P=0.023). There was no correlation between BCVA(LogMAR)after treatment and the number of CRT(rs=-0.086,P=0.600)and HRD(rs=-0.115,P=0.482), the diameter and height of SRF(rs=0.102,P=0.530; rs=0.100,P=0.538)and IRF(rs=0.134,P=0.410; rs=-0.014,P=0.932), and the width of DRIL(rs=0.089,P=0.587).CONCLUSION:The probability of retinal HRD was significantly higher in patients with no visual improvement than that in patients with visual improvement after the re-treatment with anti-VEGF due to the treatment interruption during COVID-19. EZD width was also closely correlated to the prognosis of visual acuity. As for these patients, HRD manifestations in OCT should be comprehensively considered, taking intravitreal injection of glucocorticoid as an auxiliary strategy if necessary.

OBJECTIVE: To assess changes of nutritional status by comprehensive nutrition assessment including nutritional risk screening, dietary assessment, blood biochemical index, and body composition in acute leukemia patients who had undergone chemotherapy. METHODS: A total of 169 patients with acute leukemia treated at The First Affiliated Hospital of Soochow University from June 2018 to August 2019 were recruited for this study. Before and after chemotherapy, the NRS-2002 and PG-SGA scales, dietary intake, blood biochemical index and body composition were evaluated to compare the changes of nutritional status. RESULTS: NRS-2002 score and PG-SGA score after chemotherapy were significantly increased than those before chemotherapy (P<0.001). Many patients had insufficient nutritional intake during chemotherapy, and the dietary intake score of patients with induction chemotherapy was significantly lower than that of patients with consolidation chemotherapy (P=0.043). The results of multivariate analysis showed that induction chemotherapy was the independent risk factor for the increase of PG-SGA scores and the decrease of dietary intake (all P<0.05). After chemotherapy, the white blood cell count, hemoglobin, and platelet count were significantly decreased (P<0.001), the prealbumin was significantly increased (P<0.001), and the blood glucose was increased (P=0.04), but albumin was not significantly changed. The weight, body mass index, fat-free mass, skeletal muscle mass and intracellular water were all significantly decreased (P<0.001), and visceral fat area was increased significantly after chemotherapy (P<0.05), especially in newly-diagnosed acute lymphoblastic leukemia patients after the induction of chemotherapy. CONCLUSION The nutritional status of patients with acute leukemia has undergone significant changes after chemotherapy. A single indicator has limited significance for nutritional status assessment. Comprehensive assessment of nutritional status by multiple tools is worthy of clinical application.

Objective: To understand the prevalence of chronic kidney disease (CKD) and related factors in adults in Anhui province based on the data of Chinese Chronic Diseases and Nutrition Surveillance program (2018) in Anhui. Methods: Multi-stage stratified cluster random sampling was used to select participants aged ≥18 years. Moreover, questionnaire survey, body measurements and laboratory tests were conducted. The complex weighting method was used to estimate the prevalence of CKD in residents with different characteristics, and complex sampling data logistic regression model was used for multivariate analysis to identify related risk factors. Results: A total of 7 181 participants were included. The overall prevalence of CKD was 11.06% in adults in Anhui, and the prevalence was 12.49% in women and 9.59% in men (P<0.05). The moderate, high and very high risk for CKD progression were 8.66%, 2.02% and 0.38%, respectively. Multivariate analysis showed that age (OR=1.03, 95%CI: 1.00-1.05), BMI (OR=1.05, 95%CI: 1.01-1.09), being woman (OR=1.38,95%CI: 1.22-1.55), hypertension (OR=2.50, 95%CI: 1.76-3.56), diabetes (OR=2.28, 95%CI: 1.51-3.43), dyslipidemia (OR=1.26, 95%CI: 1.11-1.43) and hyperuricemia (OR=2.16, 95%CI: 1.68-2.78) were risk factors for CKD. Conclusion: The prevalence of CKD in adults in Anhui was relatively high and age, gender, BMI, hypertension, diabetes, dyslipidemia and hyperuricemia were found to be associated with the prevalence of CKD. To prevent CKD and its complications, attention should be paid to the management of related risk factors, including overweight and obesity, hypertension, diabetes, dyslipidemia and hyperuricemia.

Methotrexate(MTX) is a commonly used antimetabolite, which can be used in the treatment of a variety of diseases. However, hepatotoxicity in the use of MTX severely limits its clinical use. Therefore, how to prevent and treat hepatotoxicity of MTX has become an urgent clinical problem. This paper summarizes and analyzes relevant literatures on the prevention and treatment of hepa-totoxicity caused by MTX with traditional Chinese medicines and natural medicines in recent years. MTX-induced hepatotoxicity mechanisms include folate pathway, oxidative stress damage and adenosine pathway, of which oxidative stress theory is the main research direction. A total of 14 kinds of traditional Chinese medicine and natural medicine extracts including white peony root, and 21 kinds of natural monomer compounds, including berberine, play an anti-MTX-induced hepatotoxic effect by resisting oxidative stress, inhibiting inflammation and regulating signal pathways. According to current studies on the prevention and treatment of hepatotoxicity induced by MTX with traditional Chinese medicines and natural medicines, there are insufficiencies, such as partial and superficial mechanism studies, inadequate combination of experimental research and clinical practice, non-standard experimental design and lack of application of advanced technologies and methods. This paper systematically reviewed the effects and mechanisms of traditional Chinese medicines and natural medicines against hepatotoxicity induced by MTX and defined current studies and deficiencies, in the expectation of proposing new study strategies and directions and providing scientific basis for rational clinical use of MTX and development of new drugs against MTX hepatotoxicity.

OBJECTIVE: To investigate the clinical effect and safety of Chinese Children's Leukemia Group (CCLG)-ALL 2008 (high risk group) protocol in the treatment with childhood Mixed phenotype acute leukemia (MPAL). METHODS: The clinical data of 15 new diagnosed patients with MPAL treated in our hospital from January 2013 to December 2017 were retrospectively analyzed, and received CCLG-ALL 2008 (high risk group) protocol chemotherapy. RESULTS: One patient gave up treatment after diagnosed, and 14 children with MPAL after induction remission chemotherapy, 3 patients gave up, and 5 patients received consolidation chemotherapy, and 6 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT). The complete remission (CR) rate was 85.7% at d33 of induction remission chemotherapy. The serious adverse event and treatment-related mortality (TRM) rate was 71.4% and 14.3%, respectively. The recurrence rate was 21.4% and the median time of relapse was 12(9.7-18.4) months. Except for 4 patients who gave up treatment, the 5-year event-free survival (EFS) rate in the other 11 patients was (54.5±15.0)%. The 5 years EFS of 4 patients who received consolidation chemotherapy was significantly lower than the 6 patients who received allo-HSCT after CR (25.0%±21.7% vs 83.3%±15.2%, P=0.033). CONCLUSION The CCLG-ALL2008 (for high-risk group) protocol in treatment of children with MPAL can get a high CR rate, but also with a high incidence of SAE. The patients received allo-HSCT after CR may have a good prognosis.

OBJECTIVE: To investigate the clinical features and prognostic factors of acute lymphoblastic leukemia (ALL) children with P2RY8-CRLF2 gene rearrangement. METHODS: A total of 108 children with B-cell ALL (B-ALL) were diagnosed and systematically treated according to Chinese Children's Leukemia Group (CCLG) -ALL 2008 in our hospital from January 2016 to December 2016. The 108 patients were divided into two groups according to the result of mutiplex polymerase chain reaction: group with P2RY8-CRLF2 gene rearrangement and group without P2RY8-CRLF2 gene rearrangement. The ALL children with P2RY8-CRLF2 gene rearrangement were all treated by CCLG-ALL 2008 high-risk group (HR) regimens, and the ALL children in group without P2RY8-CRLF2 gene rearrangement received different intensity chemotherapy according to clinical risk classification. RESULTS: Five (4 male and 1 female) out of 108 patients with B-ALL had P2RY8-CRLF2 gene rearrangement. In the 5 B-ALL patients with P2RY8-CRLF2 gene rearrangement, the median age of the was 4 (2-6) years old and the median WBC count was 26.2 (2.46-525.1)×10 CONCLUSION The early treatment response and prognosis of ALL children with P2RY8-CRLF2 gene rearrangement are worse, and more effective protocol is needed for this subtype patients.
