Objective:To explore the association between chest high resolution CT (HRCT) scoring and prognostic factors of interstitial lung disease (ILD) in patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM).Methods:The patients with DM admitted to Kailuan General Hospital between January 2017 and December 2019 were included into the study including 13 patients with positiveanti-MDA5 antibody (7 survivors, 6 deaths) and 18 patients with anti-synthase (ARS)-antibody positive. All patients underwent chest HRCT prior to treatment. The consolidation, ground-glass opacity (GGO) and fibrosis were scored to assess HRCT findings. The clinical manifestations were compared between the two groups. Cox regression analysis adjusted for age and sex was used to determine the prognostic factors for anti-MDA5 antibody-related ILD.Results:Compared with ARS patients, glutamyl transferase (GGT) and ferritin levels were significantly higher in MDA5-ILD patients [70.0(37.0, 122.5) vs 21.0(16.5, 33.5), Z=-3.37, P=0.001; 977.0(502.5, 1 366.0) vs 307.1(72.3, 546.9) , Z=-3.44, P=0.001]. The cumulative survival rate was significantly lower in patients with positive anti-MDA5 antibody than in those with positive anti-ARS antibody (100% vs 70%, P=0.001). The DM complicated with acute/subacute interstitial pneumonia (A/SIP) were found to significantly relate to death. There were no significant differences in chest HRCT scoringbetween the survivors and the deceased patients [ HR=1.08, 95% CI(0.95, 1.23), P=0.229; HR=0.97, 95% CI(0.72, 1.30), P=0.814]. Conclusion:Anti-MDA5 antibody is an important index for early diagnosis of DM complicated with acute/subacute interstitial pneumonia (A/SIP). The chest HRCT scoreis is not associated with the prognosis of anti-MDA5 antibody-related ILD patients.

Objective:To investigate the epidemiological and clinical characteristics of visceral leishmaniasis (VL) in children, and to analyze the distinguishing features of VL associated hemophagocytic lymphohistiocytosis (HLH), so that to provide reference for the diagnosis and treatment of VL.Methods:Forty-one children with VL admitted to Xi′an Children′s Hospital from July 2012 to June 2021 were enrolled. The clinical data were retrospectively analyzed, including epidemiology, clinical manifestations, laboratory data, diagnostic methods, treatment regimens and outcomes. The patients were divided into VL group and VL+ HLH group according to whether combined with HLH or not, and the clinical characteristics and laboratory findings of the two groups were compared. Two independent samples t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Forty-one children with VL were from different provinces, including Shaanxi Province (70.73%(29/41)), Gansu Province (14.63%(6/41)), Shanxi Province (12.20%(5/41)) and Ningxia Hui Autonomous Region (2.44%(1/41)), and 87.80%(36/41) of them lived in rural areas. The peak age was >1.0 to 3.0 years old (63.41%(26/41)). They were sporadic throughout the year. The main clinical manifestations included fever (97.56%(40/41)), splenomegaly (95.12%(39/41)), lymphadenopathy (82.93%(34/41)) and hepatomegaly (60.98%(25/41)). The numbers of cases that Leishman-Donovan bodies were detected in the first, second and third bone marrow smears were 36, four and one, respectively. Anemia, thrombocytopenia and leukopenia detected by blood routine test were 100.00%(41/41), 78.05%(32/41) and 58.54%(24/41), respectively. There were statistically significant differences in the platelet count, lactate dehydrogenase, alanine aminotransferase, triglycerides, fibrinogen and ferritin between VL group (28 cases) and VL+ HLH group (13 cases) ( t=-2.56, t=2.64, Z=-2.66, t=7.15, t=-5.76 and t=3.86, respectively, all P<0.050). The proportions of hepatomegaly and hemophagocytes found in the bone marrow smears in VL group were both lower than those in VL+ HLH group, and the differences were both statistically significant ( χ2=4.47 and 10.93, respectively, both P<0.050). Twelve cases with VL+ HLH were treated with antimony (for six days) and intravenous immunoglobulin, and the others were treated with antimony only. The cure rates of the patients treated with antimony for one and two courses were 92.68%(38/41) and 4.88%(2/41), respectively. The dose of antimony was increased one third and treatment course was prolonged to eight days in one cured case. After (41.36±31.49) months of follow-up, three cases recurred after five to eight months of cure and all of them were cured after one more course of treatment with antimony. Conclusions:Children with VL are mainly distributed in rural areas. The common clinical manifestations are fever and involvement of reticuloendothelial system, which are not specific. The positive rate of Leishman-Donovan bodies found in bone marrow smears is high, and a few negative cases need repeated bone marrow aspiration. Standardized treatment with antimony for VL in children is effective, and combination therapy with immunoglobulin can be considered if patients with VL associated HLH. Very few cases may recur and antimony is still effective.

OBJECTIVE: To establish a method for the determination of harmine derivative DH-330 in rat plasma and to use it for pharmacokinetic behavior evaluation of DH-330 in rats after intragastric administration. METHODS: Using tinidazole as internal standard, after pre-treatment of acetonitrile precipitated protein, UPLC-MS method was adopted to determine the plasma concentration of DH-330. UPLC analysis was performed on Waters ACQUITY BEH C18 column (50 mm×2.1 mm,1.7 μm) with mobile phase consisted of acetonitrile-methanol-0.5% formic acid aqueous solution(15 ∶ 55 ∶ 30, V/V/V) at flow rate of 0.4 mL/min, while the column temperature was 30 ℃, and sample size was 5 μL. MS analysis was conducted by electrospray ionization source, positive ion scanning, ion source temperature at 124 ℃, DH-330 detection of mass to charge ratio (m/z) of 335.8→334.8, and internal standard m/z of 247.0→81.0. Six Wistar rats were given DH-330 suspension(50 mg/kg) intragastrically. Blood samples were collected from fundus venous plexus capillary before administration (0 h) and 0.25,0.5,1,2,4,6,8,12,24 h after administration. Plasma concentration of DH-330 was determined and plasma concentration-time curves were drawn. Pharmacokinetic parameters were calculated by using Kinetica 5.0 software. RESULTS: The linear ranges of DH-330 were 25.05-2 004 ng/mL(r=0.999 8),and the limits of quantitation was 25.05 ng/mL. RSDs of intra-day and inter-day were all less than 10%. The accuracy RE was -9.76% to 4.55%. The extraction recovery was higher than 85%(RSD<5%). Stability RE was -2.53% to 2.29%. They were not affected by matrix effect or residual effect of injection. The pharmacokinetic parameters of DH-330 in rats after intragastric administration included that cmax was (1 162.43±241.72)ng/mL,AUC0-∞ was (3 242.93±652.31)ng·h/mL,t1/2 was (1.93±0.61)h, MRT was (3.23±0.30)h,CL was (16.80±5.30)L/h·kg, Vss was (54.78±19.64)L/kg. CONCLUSIONS: The established method is simple, specific, sensitive, precise and recovery, which can be used for the plasma concentration determination of DH-330 in rats. DH-330 has short half-life, rapid absorption and large apparent distribution volume after intragastric administration in rats, which indicates that it has high lipophilicity and may be mainly distributed in tissues.

Objective:To analyze the weight score and clinical application of 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) systemic lupus erythematosus (SLE) classification criteria in lupus nephritis patients.Methods:Lupus nephritis patients with renal biopsy results who were admitted in the First Affiliated Hospital of Zhejiang University College of Medicine between January 2014 and December 2018 were enrolled retrospectively. According to whether these patients were treated with glucocorticoids and/or immunosuppressants at the time of renal biopsy, they were divided into untreated group and post-treatment group. The weight scores were compared between the two groups, and the relationship between each weight score and remission after treatment was analyzed. Taking no remission as the end event, Cox regression analysis was used to analyze the influence of each weighted integral on the end event.Results:A total of 153 patients were enrolled, including 131 (85.6%) females. These were 70 (45.8%) patients in the untreated group and 83 (54.2%) patients in the post-treatment group. The patients in the untreated group had higher scores of fever (>38.3℃), blood system involvement, low complement and positive specific antibodies than those in post-treated group (all P<0.05). In a median follow-up of 34 (6-50) months, 99 patients (64.7%) achieved complete remission, 38 patients (24.8%) achieved partial remission and 16 patients (10.5%) had no remission. With no remission as the endpoint event, univariate Cox regression analysis showed that proliferative lupus nephritis (renal score of 10 points vs 8 points) and neuropsychiatric involvement were the risk factors (both P<0.05), while multivariate Cox regression analysis showed that neuropsychiatric involvement ( HR=4.758, 95% CI 1.324-17.101, P=0.017) was an independent risk factor. Conclusion:The weight scores of 2019 EULAR/ACR SLE classification diagnostic criteria have certain predictive value for remission of patients with lupus nephritis.

ObjectiveUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to identify the metabolites of harmine in rats, in order to explore the differences in distribution of metabolites in rats after single dose(40 mg·kg-1) intragastric administration of harmine, as well to speculate the metabolic pathways. MethodSD rats were given a single dose of harmine by intragastric administration. Plasma, bile, urine and feces samples were collected after administration, and the samples were processed for determination by UPLC-Q-TOF-MS. The separation was performed on an ACQUITY UPLC™ HSS T3 columu(2.1 mm×100 mm, 1.8 μm) with acetonitrile(A)-0.1% formic acid aqueous solution(B) as mobile phase for gradient elution(0-2 min, 5%A; 2-9 min, 5%-35%A; 9-9.5 min, 35%-100%A; 9.5-12 min, 100%A; 12-12.5 min, 100%-5%A; 12.5-14 min, 5%A), the mass spectra were obtained in positive ion mode with electrospray ionization(ESI), the scanning range was m/z 50-1 200. The metabolites of harmine were identified based on the information of the obtained compounds and the literature data, and the metabolic pathways were hypothesized. ResultA total of 42 compounds(harmine and its metabolites) were identified in rats, including 27 in plasma, 17 in bile, 26 in urine and 13 in feces. The metabolic pathways involved in these 42 metabolites included monohydroxylation, dihydroxylation, demethylation, glucuronidation and sulfation. ConclusionHarmine can undergo phase Ⅰ and phase Ⅱ metabolic reactions in rats, and the prototype drug is metabolized rapidly in vivo, and the metabolites are mainly excreted by the kidneys, which can provide a reference basis for the pharmacodynamics and material basis of harmine.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.
