Exosomes and long non-coding RNAs (lncRNAs) are emerging as important elements contributing to a more comprehensive understanding of cancer development and progression. The discovery of lncRNAs in exosomes further indicates their bona fide biological functional roles in cancer development and drug resistance. In this review, we describe the biogenesis of exosomes and summarize the function of exosomal lncRNAs in the field of cancer research. These findings strikingly advance current knowledge of exosomal lncRNAs and suggest that they may be promising diagnostic biomarkers and therapeutic targets for cancer.

Cancer remains a serious healthcare problem despite significant improvements in early detection and treatment approaches in the past few decades. Novel biomarkers for diagnosis and therapeutic strategies are urgently needed. In recent years, long noncoding RNAs (lncRNAs) have been reported to be aberrantly expressed in tumors and show crosstalk with key cancer-related signaling pathways. In this review, we summarized the current progress of research on cytoplasmic lncRNAs and their roles in regulating cancer signaling and tumor progression, further characterization of which may lead to effective approaches for cancer prevention and therapy.

Objective: To compare the outcomes between haploidentical donor hematopoietic stem cell transplantation (haplo-HSCT) and matched-sibling donor transplantation (MSD-HSCT) for paroxysmal nocturnal hemoglobinuria (PNH) . Methods: The clinical data of 40 PNH patients received HSCT (haplo-HSCT=25, MSD-HSCT=15) from July 2007 to May 2018 were analyzed retrospectively to compare the outcomes between haplo-HSCT and MSD-HSCT groups. Results: There were no differences in terms of gender, age, patients of PNH-AA and median time from diagnosis to transplantation between the 2 groups (P>0.05) . The median values of absolute mononuclear cell counts and CD34⁺ cells infused were 10.74 (4.80-22.86) ×10⁸/kg and 12.19 (5.14-17.25) ×10⁸/kg (P=0.866) , 3.57 (0.68-7.80) ×10⁶/kg and 4.00 (3.02-8.42) ×10⁶/kg (P=0.151) respectively, in haplo-HSCT and MSD-HSCT groups. All patients attained complete engraftment, no patient occurred graft failure. The median durations for myeloid and platelet engraftment were 12 (range, 9-26) and 11 (range, 7-15) days (P=0.065) , 19 (range, 11-75) and 13 (range, 11-25) days (P=0.027) respectively, in haplo-HSCT and MSD-HSCT groups. During a median follow-up of 26 (4-65) months in haplo-HSCT and 36 (4-132) months in MSD-HSCT groups (P=0.294) , the incidences of grade Ⅰ-Ⅳ acute graft-versus-host disease (aGVHD) were 32.0% and 20.0% (P=0.343) , grade Ⅱ-Ⅳ aGVHD were 16.0%, 13.3% (P=0.759) , chronic GVHD were 30.7% and 24.6% (P=0.418) , moderate-severe chronic GVHD were 12.7% and 7.1% (P=0.522) respectively, in haplo-HSCT and MSD-HSCT groups. The incidences of infection were 32.0% (8/25) and 26.7% (4/15) (P=1.000) respectively, in haplo-HSCT and MSD-HSCT groups. No patients occurred early death and relapse. Three-year estimated overall survival (OS) were (86.5±7.3) % and (93.3 ±6.4) % (P=0.520) , GVHD-free and failure-free survival (GFFS) were (78.3±8.6) % and (92.9±6.9) % (P=0.250) respectively, in haplo-HSCT and MSD-HSCT groups. Conclusion: The preliminary results indicated that haplo-HSCT was a feasible choice for PNH with favorable outcomes, haplo-HSCT and MSD-HSCT produced similar therapeutic efficacy.

Objective: To compare the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for paroxysmal nocturnal hemoglobinuria (PNH) with paroxysmal nocturnal hemoglobinuria-aplastic anemia (PNH-AA) syndrome. Methods: The outcomes of 46 patients who received allo-HSCT (16 PNH patients, 30 PNH-AA patients) from July 10, 2007 to June 2, 2018 were analyzed retrospectively. The conditioning regimen was busulfan, cyclophosphoramide, and ATG in haploidentical donors and unrelated donors. Patients with matched sibling donors were treated with the fludarabine, cyclophosphamide, and ATG regimen. Results: There were no differences of baseline data between the 2 groups except gender distribution and the numbers of haploidentical donor transplantation. The median values of absolute nucleated cell counts were 10.58 (3.83-13.83) ×10(8)/kg in the PNH group and 10.81 (3.96-33.40) ×10(8)/kg in the PNH-AA group (P=0.668) . The median doses of CD34(+) cells infused were 5.00 (3.14-8.42) ×10(6)/kg and 3.57 (1.97-6.17) ×10(6)/kg (P=0.002) , respectively. All patients obtained complete engraftment. The median time for myeloid engraftment were 11 (7-14) days in the PNH group and 12 (10-26) days in the PNH-AA group (P=0.003) . The median time for platelet engraftment were 13 (11-16) days and 18 (12-75) days (P=0.002) , respectively, after a median follow-up of 36 (4-132) months in the PNH group and 26 (4-75) months in the PNH-AA group (P=0.428) . There were no differences of incidence rates of acute graft-versus-host disease (aGVHD) , chronic GVHD and infection between PNH and PNH-AA groups (P>0.05) . No patient occurred early death and relapse. The estimated 3-year overall survival (OS) of PNH and PNH-AA groups were (100.0±0.0) % and (85.7± 6.6) % (P=0.141) , GVHD-free and failure-free survival (GFFS) were (100.0±0.0) %, (78.7±7.7) % (P=0.067) . Conclusions: allo-HSCT is effective for patients with PNH and PNH-AA syndrome. The preliminary results indicate that myeloid and platelet engraftment in PNH group were faster than PNH-AA group. There were no differences in OS and GFFS between PNH group and PNH-AA group.

Objective: To evaluate the outcome of combination of haploidentical donor (HID) hematopoietic stem cell transplantation (HSCT) with an unrelated cord blood unit for severe aplastic anemia (SAA). Methods: The clinical data of 127 SAA patients [including 74 male and 53 female patients, 65 very severe aplastic anemia (vSAA), the median age as 23.5(3-54) years] received HID-HSCT from September 2011 to April 2017 were analyzed retrospectively. The median interval from SAA diagnosis to transplantation was 2 (0.5-180) months. The conditioning was modified Bu/Cy+ATG/ALG-based (Busulfan + cyclophosphamide + antithymocyte immunoglobulin/antilymphocyte immunoglobulin) regimen. Cord blood units were selected based on the results of HLA typing and cell doses evaluated before freezing. Units with at least 4/6 matched HLA loci became the candidates. Prophylaxis for graft-versus host disease (GVHD) was by cyclosporine (CsA), mycophenolate mofetil (MMF) plus short-term methotrexate (MTX). Results: The median values of absolute nucleated cell counts were 10.87 (3.61-24.00)×10(8)/kg in the haploidentical grafts and 2.22 (1.10-7.30)×10(7)/kg in the cord blood units, respectively. The median doses of CD34(+) cells infused were 3.49(1.02-8.89) ×10(6)/kg in the haploidentical grafts and 0.56 (0.16-2.27) ×10(5)/kg in the cord blood units, respectively. Of the 127 patients, 5 patients occurred early death, one patient occurred primary graft failure. All 121 surviving patients attained complete haploidentical engraftment. The median durations of myeloid engraftment were 11 (9-28) days and 15 (9-330) days for platelets, with a cumulative platelet engraftment incidence of 96.1%. The incidence of infection was 58.27% (74/127). During a median follow-up of 20.5 (4-60) months, the incidence of grade Ⅱ-Ⅳ acute GVHD was 24.79% (30/121), moderate-severe chronic GVHD was 14.15% (15/106), 4-year estimated overall survival was (78.5±4.3) %, 4-year estimated failure-free survival was (77.4±4.3) %, respectively. Conclusion: Combination of HID-HSCT and an unrelated umbilical cord blood unit was a feasible choice with favorable outcome for SAA patients without matched donors.

OBJECTIVETo study the inhibition of berberine (BBR) against ECV-304 apoptosis induced by Staphylococcus aureus (S. aureus).

METHODSECV-304 cells were pre-treated with 128 microg/mL BBR for 2 h and then S. aureus was added (1:100). The viability of cells was detected by MTT (3-4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The morphological changes were observed by Hoechst 33258 staining. The protection of BBR for infected cells was detected by DNA Ladder.

RESULTSECV-304 cells' viability were not obviously affected by berberine. But S. aureus induced ECV-304 cells' viability could be significantly inhibited by pre-treatment of BBR (P < 0.05). Besides S. aureus-induced ECV-304 apoptosis could be reduced, with significantly lessened apoptotic body and unobvious DNA degradation.

CONCLUSIONBBR could significantly inhibit S. aureus induced ECV-304 apoptosis.
