Objective To investigate the apoptotic effect of petasin on myeloma RPMI 8226 cells and the mechanisms.Methods The inhibition of petasin on the proliferation of myeloma RPMI 8226 cells was tested by trypan blue assay.Apoptosis of RPMI 8226 cells was measured by terminal-deoxynueleotidyl transferase mediated dUTP nick end labeling (TUNEL)assay and Hoechst 33258 staining assay.Effects of petasin on caspase-3,8 and 9 expressions,phosphorylation of ERK1/2,MEK(p-ERK1/2 ;p-MEK)and p38MAPK(p-p38MAPK)protein were analyzed by Western blot.Results Incubation by petasin for 24 h,48 h or 72 h could significantly inhibit the pro-liferation of myeloma RPMI 8226 cells (P <0.01,P <0.01,P <0.01).Petasin induced the apoptosis of myeloma RPMI 8226 cells in time-and concentration-dependent manners (P <0.05,P <0.05).Caspase inhibitor pretreat-ment could significantly inhibit the apoptosis of myeloma cells.After cultured with petasin for 72 h,the expressions of caspase-3,8 and 9 were obviously enhanced (P <0.05,P <0.01,P <0.05)and phosphorylation of p-p38MAPK of RPMI8226 cells was significantly increased (P <0.01).However,phosphorylation of p-ERK1/2 and p-MEK was decreased significantly (P <0.01,P <0.05).Conclusion Petasin can inhibit the proliferation of myeloma RPMI 8226 cells and induce apoptosis.The mechanism may be related to the activation of caspase-3,8 and 9 proteins and the changes in phosphorylation of p38MAPK,ERK1/2 and MEK.

Objective To investigate the diagnosis and treatment of pure red cell aplasia (PRCA) caused by human parvovirus B19 (HPVB19) after liver transplantation.Method The clinical data of one case of PRCA caused by HPVB19 after liver transplantation,including clinical manifestations,diagnosis and treatment,were retrospectively analyzed,and the related literatures were reviewed.Result The first case of PRCA caused by HPVB19 after liver transplantation in our center with typical clinical manifestations of anemia was diagnosed,including dizziness,fatigue,anhelation and so on.A progressive decrease in erythrocyte count,reticulocyte count and hemoglobin level were observed by blood routine test.Bone marrow aspiration biopsy showed an absence of erythroid cells and the HPVB19 DNA test of blood was positive.Erythrocyte count,reticulocyte count and hemoglobin level were back to normal after the anti-rejection strategy changing from tacrolimus and rapamycin to cyclosporin and rapamycin and a normal human myelogram was observed by bone marrow aspiration biopsy.The DNA concentration of HPVB19 in blood was below the lower test limit.The blood test of HPVB19 DNA showed a positive result again after the anti-rejection strategy changed back to tacrolimus and rapamycin duo to increased blood creatinine level while the reticulocyte count was still in normal scale.This is the first reported case of successfully cured PRCA caused by HPVB19 in liver transplantation patients through changing the anti-rejection strategy and also the first case of HPVB19 re-infection or relapse without PRCA recurrence in liver transplantation patients.Conclusion This case may indicate the importance of immunosuppressive drug changing in the treatment of liver recipients suffering from PRCA caused by HPVB19 infection,and the genotype test may promote the understanding and treatment for this disease.

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 understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.
