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.

Objective:To investigate the work-family conflict, work withdrawal behavior and psychological resilience of postpartum female nurses with the second-child, analyze the relationships between them, further analyze whether there is a mediating role of psychological resilience between work-family conflict and work withdrawal behavior.Methods:A total of 303 postpartum female nurses with the second-child were assessed with general information questionnaire, Work-Family Conflict Scale(WFC), Conner-Davidson Resilience Scale(CD-RISC) and Work Withdrawal Behavior Scale(WWBS).Results:The total score of WFC was 53.22±13.63, and the highest score in the factor of time while lowest in the factor of behavior with 18.92±5.00,16.92±6.07. The total score of WWBS was 18.79±4.26, and the score of dimension of psychological withdrawal and behavioral withdrawal was 13.99±3.53, 4.80±1.22. The total score of CD-RISC was 88.81±16.45. The total scores and scores of each dimension of WFC were positively correlated with those of WWBS( r values were 0.122-0.396, P<0.05 or 0.01). The total scores and scores of each dimension of CD-RISC were negatively correlated with those of WWBS and WFC( r values were -0.320--0.094, P<0.05 or 0.01). Structural equation modeling analysis showed that work-family conflict indirectly affected work withdrawal behavior through psychological resilience. Conclusions:Cultivating psychological resilience shows a positive effect on easing the work-family conflict and improving work withdrawal behavior for postpartum female nurses with the second-child.

Objective:To explore the occurrence and risk factors of interstitial pneumonia (IP) in patients with diffuse large B-cell lymphoma (DLBCL) after the treatment of CHOP-like regimens containing liposomal doxorubicin.Methods:The clinical data of 145 newly diagnosed and newly treated DLBCL patients who were admitted to the Affiliated Tumor Hospital of Xinjiang Medical University from January 2013 to June 2020 were retrospectively analyzed, of which 73 cases were treated with RCDOP regimen containing liposomal doxorubicin, and 72 cases were treated with RCHOP regimen. The incidence of IP was compared between the two groups, and the risk factors of IP were analyzed by multivariate logistic regression.Results:In 145 patients, 34 patients (23.4%) developed IP; most cases of IP occurred during 3 to 5 cycles of chemotherapy, accounting for 79.4% (27/34); when IP occurred, the median cycles of chemotherapy was 4 cycles. The incidence of IP in RCDOP regimen group and RCHOP regimen group were 31.5% (23/73) and 15.3% (11/72), and the difference was statistically significant ( χ2 = 5.319, P < 0.05). Multivariate logistic regression analysis showed that the application of liposomal doxorubicin ( OR = 2.416, 95% CI 1.059-5.509, P = 0.036) and age ≥60 years old ( OR = 2.505, 95% CI 1.127-5.567, P = 0.024) were independent risk factors for the occurrence of IP. Conclusions:The application of liposomal doxorubicin is a risk factor for the occurrence of IP in DLBCL patients. The prevention and monitoring of IP should be strengthened after 4 cycles of treatment with RCDOP regimen, especially for patient ≥ 60 years of age.

Objective To analyze the genotypic characteristics of hepatitis B virus (HBV)C/D recombinant of two types of newly discovered HBV genotypea found in Western China.Methods The whole genomes of 17 HBV strains isolated from Western China were amplified by polymerase chain reaction (PCR). Bioinformatic softwares were used for the analysis of full genome structure,genetic distances and recombination points.Results The heterogenicity of the HBV C/D recombinant was more than 8% compared with genotype A,B,D,E or F,but 3.8% 0A-8.O% compared with genotype C Based on phylogenetie analysis, a11 C/D recombinant strains clustered within genotype C.but were rouped into two other clusters within the genotype C independently from C1-C5 subgenotypes,which were two kinds of new HBV/C genotypea.Condusion The HBV C/D recombinant could he considered as tWO kinds of new subgenotypea of HBV genotype C which are different from subgenotype C1-C5 based on the genetic distances analysis.
