Objective:To detect the expression level of tRF-31-PER8YP9LON4VD in the serum of breast cancer patients and to explore its effect on the function of breast cancer cells.Methods:The serums of 57 breast cancer patients, 39 breast benign tumor patients and 40 normal physical examination patients in the Affiliated Cancer Hospital of Nanjing Medical University from April to August in 2022 were collected. Real-time quantitative polymerase chain reaction(RT-qPCR) to detect the expression level of tRF-31-PER8YP9LON4VD in breast cancer cell lines and serum of breast cancer patients. Cell invasion assay, migration assay and CCK-8 proliferation assay were used to analyze the effect of tRF-31-PER8YP9LON4VD on breast cancer cell function. The receiver operating characteristic curve (ROC) curve was used to analyze the diagnostic efficacy of tRF-31-PER8YP9LON4VD in serum in breast cancer. The chi-square test was used to analyze the correlation between tRF-31-PER8YP9LON4VD and clinical features.Results:The expression levels of tRF-31-PER8YP9LON4VD in breast cancer cell lines MDA-MB-231 (0.50±0.22 vs 1.00±0.01), T-47D (0.33±0.02 vs 1.00±0.01) and MCF-7 (0.50±0.02 vs 1.00±0.01) were significantly lower than those in normal mammary epithelial cell lines (1.00±0.01), and the difference was statistically significant (all P<0.05). The expression level of tRF-31-PER8YP9LON4VD in the serum of breast cancer patients (1.35±1.25) was lower than that in the serum of patients with normal physical examination (6.42±3.13) and patients with benign breast tumors (9.57±2.11), and the difference was statistically significant (both P<0.001). Compared with the control group, the invasiveness of overexpressing tRF-31-PER8YP9LON4VD T-47D (86.67±12.22 vs 532.00±22.68, P<0.001) and MDA-MB-231 (535.33±99.12 vs 1 055.67±24.00, P=0.002) was weaker, and that of T-47D (442.67±81.79 vs 1 210.67±115.02, P=0.002) and MDA-MB-231 (278.67±108.40 vs 571.33±95.37, P=0.015) had weaker migration ability, and T-47D and MDA-MB-231 had weaker proliferative ability (all P<0.05). The area under the curve of serum tRF-31-PER8YP9LON4VD for the diagnostic efficacy of breast cancer was 0.743 (95% CI 0.644-0.842), and the sensitivity and specificity were 89.50% and 53.10%, respectively. Conclusion:tRF-31-PER8YP9LON4VD is low expressed in the serum of breast cancer patients, and it may inhibit the proliferation, migration and invasion of breast cancer cells.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

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.

AIM: To analyze the effect of the new "dual track integration" training policy on graduate students of master's degree in hematology. METHODS: The graduate students of master's degree majoring in hematology from January, 2013, to September, 2018 at the First Affiliated Hospital of Wannan Medical College were retrospectively analyzed. They were divided into the "dual track integration" training group and "non-dual track integration" training group. Their health care ethics, basic knowledge in hematology, clinical skills, medical research capabilities, and employment were compared and analyzed. RESULTS: There were no significant differences with regard to the health care ethics, and employment by class A tertiary referral hospitals of the dual track group relative to those from the non-dual track group (P>0.05); However, the dual track training group scored much higher on their basic medical knowledge, clinical skills and reasoning than that of the non-dual track training group (P<0.05); The dual track training group published fewer papers than the non-dual track group (P<0.05). CONCLUSION: The dual track training system enhances significantly clinical skills and basic medical knowledge of graduate students of master's degree. However, more attention needs to be paid to improve their research capabilities.

OBJECTIVE To study the mitigation effect and its possible mechanism of Astragalus membranaceus polysaccharide on the pulmonary hypertension induced by monocrotaline in rats. METHODS One hundred SD male rats were randomly divided into normal control group ，monocrotaline group ，A. membranaceus polysaccharide low-dose and high-dose groups. In addition to the normal control group, rats in other groups were injected with monocrotaline by single intraperitoneal injection of 60 mg/kg. On days 2 to 28 after administration ，rats in the A. membranaceus polysaccharide low-dose and high-dose groups were intraperitoneally injected with A. membranaceus polysaccharide of 200 mg/kg and 400 mg/kg，respectively，once a day. There were 25 rats in each group，and 15 rats were taken for index detection. The mean pulmonary artery pressure （mPAP）and right heart hypertrophy index （RVHI）were detected ，and morphology changes of pulmonary artery and cardiomyocytes were monitored . mRNA and protein expression of IL- 17 in their lung tissues were detected. RESULTS Compared with normal control group ，mPAP and RVHI of monocrotaline group and A. membranaceus polysaccharide groups were increased significantly （P＜0.01）；mRNA and protein expression of IL- 17 in lung tissues were significantly increased （P＜0.01），and there were obvious pathological changes in pulmonary artery and cardiomyocytes. Compared with monocrotaline group ，mPAP and RVHI were significantly decreased in A. membranaceus polysaccharide groups （P＜0.01），while mRNA and protein expression of IL- 17 in lung tissue were decreased significantly （P＜0.01）；pathological changes in pulmonary artery and cardiomyocytes were improved. Compared with A. membranaceus polysaccharide low-dose group ，above indexes and pathological changes were improved significantly in high-dose group. CONCLUSIONS A. membranaceus polysaccharide can reduce monocrotaline-induced pulmonary hypertension ，improve pulmonary artery structure and myocardial remodeling in rats ， the mechanism of which is presumably related to the down-regulation of IL- 17 expression in lung tissue of rats.

Objective:To investigate the effectiveness and safety of fully-covered self-expandable metal stent (FCSEMS) with plastic stent over the treatment of post liver transplantation anastomotic biliary stricture (AS).Methods:The clinical data of AS patients after liver transplantation admitted to the First Affiliated Hospital of Sun Yat-sen University from January 2014 to April 2018 was collected for the retrospective study. According to different implanted stents, patients were divided into FCSEMS group and plastic stent group. The general information of the two groups of patients, surgical success rate, postoperative complications, the number of endoscopic retrograde cholangiopancreatography (ERCP), the number of indwelling stents and other indicators were compared and analyzed.Results:A total of 54 patients were enrolled, including 41 males and 13 females, with a median age of 48 (34-65) years. A total of 23 cases were included in the FCSEMS group and 31 cases were included in the plastic stent group. The overall technical success rate of the operation was 98.3% (176/179). In the FCSEMS group, there were 21 patients recovered and 2 patients were relieved; in the plastic stent group, 29 patients were recovered, 1 case was relieved, and 1 case failed. There were no statistically significant differences in the efficacy and complication rate between the two groups (all P>0.05). The median stent indwelling time, ERCP times, and the number of indwelling stents in the FCSEMS group were 5.9 months, 2 times, and 1, respectively, and in the plastic stent group were 9.5 months, 4 times, and 8 respectively. There were statistical differences between the two groups (all P<0.05). Conclusions:FCSEMS for treatment of AS showed less duration of stenting, numbers of stents and endoscopic treatment sessions with the similar efficacy as plastic stents. It’s indicated that it’s necessary to pay attention to the probability of stent migration and pancreatitis.

Objective To explore the mechanisms of ligament of Marshall (LOM) initiat and sustain atrial fibrillation (AF).Methods The electrophysiologic properties of canine LOM were investigated using multipolar catheter mapping(normal canines,n =4,group A;AF canines,n =5,group B).The programmed stimulation were performed in the LOM,PV-left atrium(LA)junction and LA,respectively.Activations maps of LOM were analyzed from episodes of spontaneous onset of AF and initiation of induced AF by a single extrastimulus.The effectives refractory period of each part was compared and statistically analyzed among three parts in each group and between the two groups.LOM were cutted with surgical incision technology.The inducing rate of AF and the mapping rate of double potential and fragmented electrocardiogram were compared and statistically analyzed pro and post isolation of LOM.Results The incidence of abnormal potential of LOM in the two groups was significantly different(P ＜0.01),re-entry cycle(group A 25％ vs.B group 80％),tachycardia(group A 25％ vs.B 100％),double potential(group A 25％ vs.group B 80％),fragmentation potential(group A 25％ vs.group 80％).There was a significant difference in the rate of LOM tachycardia induction before and after LOM intervention in group B (P ＜ 0.05,before 100％ vs.after 20％).Conclusion There are two possible mechanisms of LOM involved in the occurrence and maintenance of AF:one is that LOM induces AF through spontaneous excitation,the other is that LOM participates in the reentry of left atrium and pulmonary vein in the form of bypass to induce and maintain AF.

In this cross-sectional study, consecutive Chinese Han ethnic inpatients in the Division of Cardiology, the First Affiliated Hospital of Soochow University from January 1, 2010 to December 31, 2013 were included. According to the exclusion criteria, 9 587 patients [1 604 with type 2 diabetes mellitus (T2DM) and 7 983 without T2DM]were obtained for final analysis. Logistic regression model was used to analyze the association of ApoB/A-1 ratio with T2DM and the possible interactions between ApoB/A-1 ratio and other risk factors. The results showed that the distribution of ApoB/A-1 ratio was positively skewed in Chinese Han ethic population. The median of ApoB/A-1 ratio of female was lower than that of male (0.68 vs 0.73,P<0.01). In all groups, the proportion of T2DM was increased with the raised ApoB/A-1 ratio. By the stratification analyses of sex, age, coronary artery disease, and the use of statins, ApoB/A-1 ratio was still correlated with T2DM. There existed significant interactions between ApoB/A-1 ratio and the smoking status or creatinine in T2DM.

Objective To investigate the correlation between the elastographic characteristics of liver and postoperative function of liver allografts.Methods Forty-eight cases of liver transplantation from The First Affiliated Hospital of Sun Yat-sen University were analyzed,Shear wave elastography (SWE) was performed before operation or at one week or one month post-operation.Liver function was evaluated by measuring alanine aminotransferase (ALT),aspartate transaminase (AST),total bilirubin (TBIL),γ-glutamine transferase (GGT),albumin (ALB),alkaline phosphatase (ALP),prothrombin time (PT),activated partial thromboplastin time (APTT),and international normalized ratio (INR).Early allograft dysfunction (EAD) was also analyzed with reference to SWE among liver transplant recipients.Results SWE at one week after transplantation was significantly correlated with TBIL (r=0.525 6,P<0.01),APTT (r=0.668 3,P<0.000 1),PT (r=0.593 7,P=0.000 1),INR (r=0.609 6,P<0.000 1) and prealbumin (r=-0.464 1,P<0.01).However,no significant correlation was observed between pre-operative SWE and parameters of post-operative liver function.SWE in EAD patients was higher than that of patients without EAD (17.60±1.09 kPa vs.13.38±0.99 kPa,P<0.01).The optimal cut-off value of SWE at one week post-operation was 14.85 kPa.Conclusion Postoperative SWE is significantly correlated with postoperative liver function tests and EAD,suggesting SWE is a potential test for evaluating the quality of liver allografts.
