Abstract
PURPOSE/OBJECTIVE(S) Though outcomes of patients with multiple myeloma (MM) have improved, cure remains elusive. Allogeneic hematopoietic stem cell transplantation (allo-sCT) is associated with a lower relapse rate, but its role is hindered due to toxicities. We hypothesized that targeted total body irradiation in the form of total marrow irradiation (TMI) could safely facilitate allo-SCT via an improved toxicity profile. Therefore, we conducted a phase I study to investigate the safety and feasibility of a bortezomib (BTZ), fludarabine (FLU), and melphalan (MEL), with or without TMI, prior to allo-SCT for patients with high-risk (HR) or relapsed/refractory (R/R) MM. MATERIALS/METHODS Between 2012 and 2018 this study enrolled patients with HR or R/R MM on one of two strata, each comprising BTZ dose-escalation cohorts. Patients aged 18-60 with no prior radiation (RT) received TMI at 900 cGy (in 6 fractions delivered twice-daily), FLU, and MEL conditioning, with BTZ added in the second cohort (stratum I). Patients aged 18-70 with prior RT received FLU, MEL, and BTZ, without TMI (stratum II). The primary endpoint was feasibility of escalating doses of BTZ, with or without TMI, defined using a 3+3 design. Dose-limiting toxicity (DLT) was defined as any Grade 3+ Bearman toxicity or prolonged CTCAE v4.0 Grade 4+ neutropenia. Secondary endpoints included treatment response, time to neutrophil and platelet engraftment, incidence of acute (a) and chronic (c) graft-versus-host disease (GVHD), progression-free-survival (PFS), and overall survival (OS). RESULTS Eight patients were enrolled on stratum I. One of three patients in the first cohort of stratum I experienced DLT, which led to expansion to three more patients with no DLT. Cohort 2 enrolled only 2 patients due to low accrual, with BTZ added at 0.5 mg/m2; neither experienced DLT. Nine patients were enrolled on stratum II. Three patients were enrolled on cohort 1 (BTZ 0.5 mg/m2) and none experienced DLT. Three were enrolled on cohort 2 (bortezomib 0.7 mg/m2), and one experienced DLT. Therefore, the cohort expanded to three more patients. One more patient experienced DLT and 0.5 mg/m2 was considered the maximum tolerated dose. There were no primary or secondary graft failures. Complete response was achieved in 7 and 4 patients in strata I and II, respectively. Median follow-up for all patients was 30.7 months (mos) and was 99.8 mos for surviving patients. Median overall survival (OS) on strata I and II were 44.5 mos and 21.6 mos, respectively. Median PFS on strata I and II were 18.1 mos and 8.9 mos, respectively. In strata I, 5 patients developed Grade 2+ aGVHD and 8 developed extensive cGVHD. In strata II, 4 patients developed Grade 2+ aGVHD and 6 developed extensive cGVHD. CONCLUSION The TMI 900 cGy, FLU, and MEL conditioning regimen is considered safe as conditioning for allo-SCT and may warrant further investigation due to favorable response rates and survival; the conditioning regimen of FLU, MEL, and BTZ (0.7 mg/m2) is associated with unacceptable toxicities.

Abstract
Objective: To explore the association between gallbladder adenomyomatosis (GA) and occult pancreaticobiliary reflux (OPBR). Methods: A total of 81 patients with GA who underwent cholecystectomy in Shanghai East Hospital from December 2020 to January 2022 were enrolled, including 48 cases of fundal type, 28 cases of segmental type and 5 cases of diffuse type. Patient's intraoperative bile was coltected and tested for amylase. According to gallbladder bile amylase level, patients were divided into OPBR group (bile amylase>110 U/L) and the control group (bile amylase≤110 U/L). Results: Among 81 patients, 32 were male and 49 were female, and aged (49.1±13.2) years; there were 66 cases in control group, including 27 males and 39 females, and aged (50.0±12.9)years; there were 15 patients in the OPBR group, including 5 males and 10 females, and aged (45.1±14.2) years. In terms of the clinical features of the two groups, there was no significant difference (all P>0.05), except for a significant increase in biliary amylase in the OPBR group compared with the control group (P<0.001). However, the incidence of OPBR was significantly different in the three types of GA, with a lower incidence of OPBR in the fundal type (10.4%, 5/48) than in the segmental type (28.6%, 8/28) and diffuse type (2/5) (P=0.038). In addition, segmental GA was more likely to be combined with gallbladder stones (85.7%, 24/28) than fundal GA (58.3%, 28/48) and diffuse GA (3/5) (P=0.031). Univariate and multivariate logistic regression analyses showed OPBR [OR (95%CI)=3.410 (1.010 to 11.513), P=0.048] and combined gallbladder stones [OR (95%CI)=2.974 (1.011 to 8.745), P=0.048] indepenclently correlated with segmental and diffuse GA. Conclusions: The incidence of OPBR is higher in segmental and diffuse GA, and gallstones and OPBR are independently associated with the occurrence of segmental and diffuse GA. These results suggest that OPBR may be the initiating factor for the occurrence and carcinogenesis of segmental and diffuse GA.

Abstract
Circular ATP binding cassette subfamily B member 10 (circABCB10) has been identified to have oncological functions in several tumors. However, the roles of circABCB10 in rectal cancer remain unknown. The expression of circABCB10, microRNA (miR)-326 and C-C motif chemokine ligand 5 (CCL5), and apoptosis related-protein was detected using quantitative real-time polymerase chain reaction or western blot, respectively. Cell survival or apoptosis was measured using cell counting kit-8 assay or flow cytometry. The accumulations of intracellular lipid reactive oxygen species (ROS) and Fe2+ were analyzed using C11-BODIP dye or iron kit assay, respectively. In vivo experiments were conducted using the murine xenograft model. The interaction between miR-326 and circABCB10 or CCL5 was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation assay. CircABCB10 and CCL5 were upregulated but miR-326 was downregulated in rectal cancer. The knockdown of circABCB10 promoted rectal cancer cell ferroptosis and apoptosis in vitro as well as inhibited tumor growth in vivo. miR-326 was a target of circABCB10, and the miR-326 inhibition could partially attenuate circABCB10 deletion-induced cell ferroptosis and apoptosis. miR-326 directly interacted with CCL5, and the miR-326 inhibition suppressed cell ferroptosis and apoptosis by targeting CCL5. Besides, we observed that miR-326 was negatively regulated by circABCB10, while CCL5 was positively regulated by it, and circABCB10 served as a sponge of miR-326 to regulate the CCL5 expression in rectal cancer cells. CircABCB10 silence promoted rectal cancer cell ferroptosis and apoptosis by regulating the miR-326/CCL5 axis, suggesting a potential therapeutic target for rectal cancer therapy.

Abstract
A full length cDNA fragment encoding for human thrombopoietin receptor c-Mpl has been amplified by RT-PCR from the total RNA of human HEL cells. The complete sequence of the cloned cDNA was determined and is identical to that previously reported. Then the fragment was subcloned into the mammalian expression vector pcDNA3 and the resulting plasmid is designated as pcMPL. K562 cells, which do not express c-mpl, were transfected with pcMPL and pcDNA3, respectively. The transformants were selected with G418 and then tested by Northern and Southern blotting. A group of engineered cell lines stably expressing c-mpl have been obtained, which will facilitate further research on the signaling mediated by c-Mpl.

Abstract
Neural cell adhesion molecule L1 is an important molecule mediating cell-cell interactions during the development of nervous system. L1 can promote axonal outgrowth and is related with nerve cell migration, and therefore L1 plays an important role both in the development and maintaince of the nervous system. In humans, mutations in the L1 gene can lead to mental retardation, spastic paraplegia, hydrocephalus, and other developmental abnormalities. The molecular mechanisms of mutations in L1 gene to induce inherited neurological diseases are not clear. In present investigation, a transgenic DNA of mouse L1 extracellular domain (L1ECD) was constructed by adding a stop codon to the end of L1ECD cDNA and then putting it under the control of CAMK II promoter, which is active specifically in the brain. To verify this construct, L1ECD cDNA was subcloned into an expression vector pCEP4 and then transfected the C6 cells. The expression of L1ECD cDNA in C6 cells was confirmed by Northern blotting and the effects of L1ECD on the growth rate and morphology of C6 cells in vitro as well as primarily cultured neurons were observed. The L1ECD constructs were microinjected into the fertilized zygotes of C57BL/6 mice. The transgenic mice thus produced were identified by Southern and Northern hybridization analysis. The results demonstrated that the L1ECD was integrated in the genome of transgenic mice and expressed specifically in the brain.
