OBJECTIVE: To analyze the correlation between Cobb angle and spinous process angle (SPA) on X-ray film and body surface in patients with mild to moderate adolescent idiopathic scoliosis(AIS). To explore the possibility of linear SPA to assess scoliosis. METHODS: Retrospective study for correlation of Cobb angle and linear SPA on X-ray film. AIS patients treated and taken full spine anteroposterior X-ray from January 2019 to December 2021 were analyzed correlation of Cobb angle and linear SPA on X-ray film. Prospective study for correlation of Cobb angle and body linear SPA. AIS patients treated and taken full spine anteroposterior X-ray from December 1 to December 9 this year were analyzed correlation of Cobb angle and body linear SPA. RESULTS: A total of 113 AIS patients with age an average of (14.02±2.16) years old(ranged from 10 to 18 years old) were recruited in retrospective study, involving 26 males and 87 females;there were 71 patients with mild AIS and 42 patients with moderate AIS. Cobb angle in AIS patients was significantly inversely associated with SPA(r=-0.564, P<0.001), the linear regression equation was:Cobb angle=169.444-0.878×SPA. Cobb angles in patients with mild scoliosis were significantly and inversely associated with SPA(r=-0.269, P=0.012), the linear regression equation was:Cobb angle=46.832-0.185×SPA. Cobb angles in patients with moderate scoliosis were also clearly correlated with SPA(r=-0.417, P=0.003), the linear regression equation was:Cobb angle=113.889-0.516×SPA. Thirty-eight patients were recruited in prospective study. The mean Cobb angle and body linear SPA were(18.70±6.98)°, ranged from 11.3° to 36.0° and (170.34±4.57)°, ranged from 162.1° to 177.7° respectively. There was significantly negative correlation(r=-0.651, P<0.001), the linear regression equation is:Cobb angle=187.91-0.99×SPA. CONCLUSION Linear SPA on X-ray film or on the body was significantly negatively correlated with Cobb angles, but the regression equation fits poorly, so it's not suitable for diagnosis of scoliosis;however, linear SPA is appropriate for self-controlled assessment of scoliotic therapy or for dynamic assessment of spinal flexibility.

Objective: To explore the long-term clinical efficacy of transcatheter repair of mitral paravalvular leak (PVL) post surgical mitral valve replacement. Methods: This study is a retrospective study. Patients who completed transcatheter repair of paravalvular leak after surgical mitral valve replacement at Shanghai Chest Hospital, Shanghai Jiaotong University School of Medicine from March 2010 to December 2018 were included. Technical success was defined as the occluder being stably implanted in the paravalvular leak site without affecting the function of the mitral valve and surrounding tissues; and there were no intervention-related complications, such as new hemolysis or aggravated hemolysis, and echocardiography confirmed mitral paravalvular regurgitation reduced by more than 1 grade. Patients were followed up at 30 days, 1, and 3 years after the intervention. The main endpoints were all-cause death and re-surgery due to interventional failure or serious complications. The occurrence of occluder-mediated hemolysis and chronic renal insufficiency was recorded, and patients were monitored with echocardiography during follow up. Results: A total of 75 patients were included, aged (54.3±22.9) years old, and 38 patients were males. All patients had decreased cardiac function and/or hemolysis before intervention. Procedural success was achieved in 54 patients (72.0%). Incidence of device-mediated hemolysis was 18.7% (14/75). During the follow-up period, all-cause death occurred in 7 patients (9.3%), and 3 were cardiac deaths.The 3-year event-free survival rate was 81.3% (61/75). The need for cardiac surgery was 9.3% (7/75): 3 cases due to severe device-mediated hemolysis, 2 cases due to prosthetic valve failure and 2 cases due to moderate to severe residual regurgitation. The echocardiography follow-up results showed that the position of the occluder was stable, there was no impact on the artificial valve function and surrounding structures, and the residual regurgitation was stable without progressive increase in event-free patients. Compared with pre-intervention, the left ventricular end systolic diameter ((33.9±7.4)mm vs. (38.3±8.9) mm, P=0.036), end diastolic diameter ((53.7±8.3) mm vs. (58.4±9.1) mm, P=0.045) and left atrial diameter (59.3 (44.5, 90.7) mm vs. 64.3 (44.8, 96.6) mm, P=0.049) were significantly reduced, pulmonary artery systolic pressure was also significantly decreased ((36.5±15.8) mmHg vs. (46.3±14.9) mmHg, P=0.022, 1 mmHg=0.133 kPa). There was no significant difference between 3 years and 1 year after transcatheter repair of mitral paravalvular leak post surgical mitral valve replacement (all P>0.05). Conclusion: Transcatheter repair of mitral paravalvular leak post surgical mitral valve replacement is an effective treatment option in selective patients.

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis and high mortality. In this study, we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine α-1,3-galactose epitopes (αGal) and endorphin extracellular domains (END) with dendritic cells (DCs) from healthy volunteers. END⁺/Gal⁺-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes (CTLs) and secretion of interferon-gamma (IFN-γ). CTLs targeted cells expressing αGal and END and tumor angiogenesis. The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice, indicating the high clinical potential of this new cell based vaccine.

OBJECTIVE: To investigate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of acute monocytic leukemia (AML-M5) and the related factors that affecting the prognosis of the patients. METHODS: The clinical data of 71 patients with AML-M5 treated with allo-HSCT in Zhujiang Hospital Affiliated to Southern Medical University from April 2009 to October 2019 were collected and retrospectively analyzed. The incidence of graft-versus-host disease (GVHD), cumulative overall survival (OS) rate, cumulative progression-free survival (PFS) rate, transplantation-related mortality (TRM), relapse rate and the risk factors affecting prognosis in the patients were analyzed. RESULTS: 66 patients obtained hematopoietic reconstruction after transplantation, the median time of granulocyte implantation was 12 (9-26) d, and the median time of megakaryocytic implantation was 13 (8-72) d. The incidence of acute GVHD and chronic GVHD was 33.8% (24/71) and 36.6% (26/71), respectively. The median follow-up time was 13.81 (0.16 to 112.54) months; the median OS and PFS was 31.27 and 26.07 months, respectively. The cumulative OS of the patients in 1 and 3 years after transplantation was 64.9% and 48.6%, respectively, and the cumulative PFS of the patients in 1 and 3 years was 55.0% and 39.5%, respectively. The cumulative relapse rate of the patients in 1 and 3 years was 24% and 40%, respectively. Multivariate analysis showed that pre-transplantation relapse was the independent risk factor affecting OS (HR=2.32, 95%CI:1.17-4.62, P=0.02) and PFS (HR=3.08, 95%CI:1.61-5.90, P=0.001) of the patients; invasive fungal disease after transplantation was the independent risk factor affecting OS (HR=2.71, 95% CI:1.32-5.56, P=0.007) and PFS (HR=2.87, 95%CI=1.40-5.86, P=0.004) of the patients; FLT3 mutation was the independent risk factor affecting PFS (HR=2.13, 95%CI=1.07-4.24, P=0.03) of the patients. CONCLUSION AML-M5 is the intermediate or high-risk leukemia, and allo-HSCT can improve the survival prognosis of the patients. Pre-transplantation relapse and invasive fungal disease after transplantation are the important factors affecting the efficacy of allo-HSCT in patients with AML-M5.

OBJECTIVE: To summarize the clinical characteristics of patients with acute myeloid leukemia-type M (AML-M) and analyze the factors affecting the prognosis. METHODS: One hundred eighty-eight AML-M patients were retrospectively analyzed for the following parameters including peripheral blood, immune phenotypes, fusion genes and cytogenetics to explore their significance for the overall survival (OS) and progression-free survival (PFS). The prognostic factors were also analyzed. RESULTS: Among 188 patients with AML-M, the chromosomal abnormality with t (8;21), normal chromosome and other abnormalities accounted for 37% (70/188), 41% (77/188) and 22% (41/188), respectively. For the immunopheno typing of M patients, the hematopoietic progenitor cell differentiation antigen CD117 (96.1%) were mainly expressed, CD34 (81.6%) and HLA-DR (55.9%), and myeloid-associated antigen of CD13 (90.5%) and CD33 (89.4%) were also highly expressed. There were lymphoid-associated antigens expressed in some patients, among which the positive expression rate of CD19 was highest (29.6%), and the next was CD7 (28.5%). The most common accompanied mutations was FLT3 mutation (30.2%). The univariate analysis showed that the patients at age＜50 years old, without extramedullary infiltration, with positive expression of CD19, NPM-1 (-), CEBPA double mutation(+), and HSCT were significant superior in OS and PFS (P＜0.05); the multivariate analysis showed that the patient at age＜50 years old, without extramedullary infiltration, with positive expression of CD19 and CEBPA double mutation (+) were significant superior in OS and PFS (P＜0.05). The analysis indicated that the Karytypes affected only OS (P＜0.05), while the NPM-1 gene mutation positive affected only PFS (P＜0.05). The univarate analysis of factors affecting the survival in 70 AML-M patients with t (8;21) abnormatity showed that the C-KIT gene mutation was a poor factor for OS and PFS. CONCLUSION The clinical characteristics are different between M patients with different karyotype, and prognostic analysis shows that the karytypes have an impact on overall survival; age, extramedullary infiltration, CD19 expression and CEBPA double mutation are also the main factors impacting the prognosis of patients.

AIM:To explore the expression level of tristetraprolin(TTP)in rats after subarachnoid hemor-rhage(SAH)as well as the potential role of TTP in the early brain injury(EBI)after SAH in rats.METHODS:In the first experiment setting,total 56 adult male SD rats were randomly divided into sham group and SAH group.The SAH mod-el was performed by endovascular perforation.The brain tissues were taken out after SAH at 5 different time points(0,12, 24,48,72 h and 1 week).The expression of TTP in the brain tissues was detected by Western blot.In the second experi-ment,a total of 60 SD rats were divided into 4 groups: sham group, SAH group, SAH +vector group and SAH +TPP group.Neurological score,brain water content and blood-brain barrier were evaluated at 48 h after SAH.TUNEL staining was performed to detect cell apoptosis in the rat brain tissue.ELISA method was used for quantitative detection of interleu-kin-6(IL-6)and tumor necrosis factor-α(TNF-α).The protein levels of TTP,Bax,Bcl-2 and cleaved caspase-3 in the rat brain tissue were detected by Western blot.RESULTS:The protein expression of TTP in the brain was downregulated markedly from 12 h after SAH,reached the lowest level at 48 h,and then had an upward trend.After modeling for 48 h, Garcia neurological score was significantly reduced,and brain water content and Evans blue(EB)content of the brain tis-sue of the rats in SAH group were significantly higher than those in sham group(P<0.05).SAH induced significant in-creases in IL-6 and TNF-αlevels in the brain tissue(P<0.05).The number of TUNEL-stained cells was increased in the subcortical brain region after SAH compared with sham group.In addition,a lower level of Bcl-2 and higher levels of Bax and cleaved caspase-3 in the rat brains were observed at 48 h after SAH.However,the neurological deficit score was signif-icantly increased,and the brain water content and EB content in the rat brains were significantly reduced in SAH +TTP group in comparison with SAH +vector group(P<0.05).Over-expression of TTP dramatically suppressed the levels of IL-6 and TNF-αin the rat brains,and reduced the number of TUNEL positive cells.Furthermore,upregulation of TTP signifi-cantly decreased the levels of cleaved caspase-3 and Bax, and evidently enhanced the expression of Bcl-2(P<0.01). CONCLUSION:The expression of TTP is significantly decreased in early period after SAH, and enhancing the level of TTP effectively inhibits EBI following SAH in rats.

OBJECTIVESTo explore the effect of additional chromosomal abnormalities on the prognosis and outcome of CML-CP patients receiving imatinib therapy.

METHODSThe clinical and genetic data of 589 CML-CP patients receiving imatinib treatment between May 2009 and October 2014 in the 1st Affiliated Hospital of Soochow University were analyzed, the 589 patients were divided into 5 groups according to the karyotypes at the initial diagnosis. The OS(overall survival), PFS (progression-free survival), EFS (event-free survival), Cumulative MMR (major molecular remission) and Cumulative CCyR (complete cytogenetic remission) were calculated by using the Kaplan-Meier method and compared by using the log-rank text by Graphpad 6.0. The χ test was used to compare the frequency of optimal molecular response at 3, 6, 12 months among the 5 groups.

RESULTSThere was significant difference about the frequency of optimal molecular response at 3 and 6 months between CML-CP patients with additional chromosomal abnormalities and those with classic t(9;22) ［50%（12/24） vs. 73.94%(261 /353), P<0.05; 50%(10 /20) vs. 72.05%(232 /322) (P<0.05)］, and the same significant difference was found at 6 months between the group with variant translocations and that with classic t(9;22) ［53.3% (16 /30) vs. 72.05%(232 /322) (P<0.05)］. The P values of cumulative CCyR (P<0.05) and EFS (P<0.01) for 4 years were statistically significant between CML-CP patients with additional chromosomal abnormalities and the other 4 groups. Compared one to another, there was the significant difference in cumulative CCyR and EFS for 4 years between CML-CP patients with additional chromosomal.abnormalities and those with classic t(9;22) (47.25% vs. 84.01%)(P<0.05); (75.03% vs. 90.01%)(P<0.01).

CONCLUSIONThe additional chromosomal abnormalities influence the outcome of CML-CP patients receiving imatinib treatment, which make poor prognosis.
