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.

Objective:To explore the clinical application of preimplantation genetic testing for monogenic disorders (PGT-M) in an unique case with Spinal muscular atrophy (SMA) type 2+ 0.Methods:A special SMA family presented at the Third Affiliated Hospital of Guangzhou Medical University on October 19, 2020 was selected as the study subject. Multiple ligation-dependent probe amplification (MLPA) and molecular tagging linkage analysis were carried out to identify the SMN1 genotype of the couple and their fetus. Subsequently, next-generation sequencing (NGS), molecular tagging linkage analysis, and chromosomal microarray analysis were employed to determine the haplotypes and validate the result of PGT-M on the 11 embryos derived for the couple. Results:The female partner was identified as a carrier of the rare SMN1[2+ 0] variant, and prenatal diagnosis confirmed the fetus to be affected by SMA. Ultimately, PGT-M has successfully selected four embryos free from the pathogenic SMN1 variants and X chromosome deletion. Conclusion:PGT-M can effectively prevent the transmission of rare genetic variants such as the SMA 2+ 0 subtype in the families. Above finding has provided guidance for genetic counseling and family planning for the couple.

Objective To investigate the effect of meridian-unblocking and mind-regulating acupuncture pretreatment on neurobehavioral functions and cerebral water content and explore its mechanism for modulating miRNA664 and MMP9 expressions in cerebral ischemia/reperfusion rats.Methods One hundred and thirty Wistar rats were randomized into group A (electroacupuncture pretreatment) of 30 rats, group B (moxibustion pretreatment) of 30 rats, group C (aspirin pretreatment) of 30 rats, group D (model) of 30 rats and group E (blank control) of 10 rats. Group A received electroacupuncture; group B, suspended moxibustion with moxa sticks; group C, an oral gavage of aspirin 10 mg/kg. A model of cerebral ischemia/reperfusion was made in every group after seven days. Rat neurobehavioral functions were observed and cerebral water content and relative miRNA664 and MMP9 expressions in the cortical region were determined at 24 hours after reperfusion.Results There was a statistically significant difference in the neurobehavioral score between group A, B, C or D and group E (P<0.01), between group A or B and group C (P<0.01) and between groups A and B (P<0.01). There were statistically significant differences in cerebral water content and relative miRNA664 and MMP9 expressions between group A, B, C or D and group E (P<0.01,P<0.05), between group A, B or C and group D (P<0.01), between group A or B and group C (P<0.01,P<0.05) and between groups A and B (P<0.01,P<0.05).Conclusions Meridian-unblocking and mind-regulating acupuncture pretreatment can effectively decrease the neurobehavioral score and cerebral water content and reduce relative MMP9 expression through modulating miRNA664 expression in cerebral ischemia/reperfusion rats. One of the mechanisms of Du meridian-unblocking and mind-regulating acupuncture pretreatment for protecting the brain may be reducing relative MMP9 expression, inducing tolerance to cerebral ischemia and relieving cerebral edema by the modulation of miRNA664 expression.
