Objective:To evaluate the promoting surgery incision healing effect of recombinant human acidic fibroblast growth fac-tor ( rh-aFGF) in the treatment of children with open fractures. Methods:A multicenter, randomized and controlled clinical trial was conducted to study the efficacy of rh-aFGF. Totally 120 cases of injured children (age<14y) were randomly divided into two groups, the treatment group (n=60) was given rh-aFGF washing during the operation and spraying after the operation, and the control group ( n=60) was treated with normal saline. Both groups were given traction, screw or Kirschner wire fixation. The healing time, healing status and delayed healing were observed and compared in the two groups. Results:Stage I healing rate, the complete healing time and delayed healing rate in the treatment group was 86. 6%, (20. 3 ± 5. 6)d and 3. 3%, respectively, while that in the control group was 56.7%, (23.4 ±6.2)d and 15.0%, respectively. The differences between the two groups were significant (P<0.05 or 0.01). Conclusion:Rh-aFGF can effectively promote wound healing and shorten the healing time. For all these positive aspects,rh-aFGF de-serves wider clinical application in postoperative rehabilitation after open fractures.

Objective:To investigate the clinical features of IgD multiple myeloma (MM) and the effect and prognosis of daratumumab-based combination therapy.Methods:The clinicopathological data of a IgD MM patient with disease progression and extramedullary infiltration treated with daratumumab in the Affiliated Hospital of Qingdao University in December 2019 were retrospectively analyzed.Results:The 74-year-old woman was diagnosed as IgD MM by bone marrow aspiration and immunofixation electrophoresis. The patient was given VD (bortezomib, dexamethasone), RD (lenalidomide, dexamethasone) and ID (ixazomib, dexamethasone) regimens. In June 2020, the patient developed multiple subcutaneous nodules, and she was assessed as progressive disease with extensive extramedullary infiltration. After treated with daratumumab-PAD (liposomal doxorubicin, bortezomib, dexamethasone) regimen, the patient's subcutaneous nodules were significantly reduced and partially disappeared, and the general condition was significantly improved. But the patient was in a cachexia state and finally died of the irregular treatment and disease progression.Conclusions:IgD MM has a low incidence and a short survival period, and there is no uniform standard treatment. The early application of daratumumab combined with proteasome inhibitors, immunomodulators, cytotoxic drugs and hematopoietic stem cell transplantation may improve the overall survival of patients.

Objective:To investigate the efficacy and safety of daratumumab (Dara) - combination regimens for newly diagnosed multiple myeloma (NDMM).Methods:A retrospective case series study was conducted. The clinical data of 34 patients with NDMM receiving treatment regimen including Dara from Qilu Hospital of Shandong University, Yantai Yuhuangding Hospital, Huangdao Branch of Affiliated Hospital of Qingdao University and Taian City Central Hospital between April 2020 and March 2022 were retrospectively collected. The efficacy, survival and adverse reactions of patients were analyzed. Cox proportional risk model was used to analyze the factors affecting overall survival (OS) and minimal residual disease (MRD) turning negative.Results:Among 34 patients with NDMM, there were 19 males and 15 females, with 21 cases aged < 65 years and 13 cases aged ≥65 years. The median follow-up duration [ M ( Q1, Q3)] was 22 months (19 months, 26 months), the median of Dara treatment cycles was 7 (5, 11), and the overall response rate (ORR) reached 97.1% (33/34). There were statistically significant differences in the optimal efficacy of patients stratified by receiving hematopoietic stem cell transplantation or not and receiving different treatment cycles (all P ≤ 0.05), while there were no statistically significant differences in patients stratified by other clinical features (all P > 0.05). The 1-year progression-free survival rate was 79.4% and the 1-year OS rate was 94.1%. Multivariate Cox regression analysis showed that the cycle number of treatment regimens containing Dara was an independent influencing factor of MRD turning negative (6 cycles vs. 2 cycles, HR = 0.267, 95% CI: 0.076-0.935, P = 0.039); age ≥ 65 years was an independent risk factor for OS ( HR = 35.313, 95% CI: 1.709-729.669, P = 0.021). The incidence of hematological adverse reactions grade 3 or above was 20.6% (7/34), and the non-hematological adverse reactions primarily included infection [44.1% (15/34)] and edema of extremity and trunk [41.2% (14/34)]. Conclusions:The Dara-based regimens for NDMM exhibit a high ORR. The remission depth accelerated with the increasing number of treatment cycle, and the adverse reactions are mild.
