Objective:To evaluate the efficacy and safety of chimeric antigen receptor T-cell (CAR-T) therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with Ph-like acute lymphoblastic leukemia (Ph-ALL) .Methods:Patients with Ph-ALL who underwent CAR-T therapy followed by allo-HSCT from March 2018 to August 2023 at the First Affiliated Hospital of Soochow University were included, and their clinical data were retrospectively analyzed.Results:Of the 21 patients, 14 were male and 7 were female. The median age at the time of CAR-T therapy was 22 (6-50) years. Seven patients had ABL1-like rearrangements, and 14 had JAK-STAT rearrangements. Prior to CAR-T therapy, 12 patients experienced hematologic relapse; 7 were multiparameter flow cytometry minimal residual disease (MFC-MRD) -positive and 2 were MFC-MRD-negative. CAR-T cells were derived from patients’ autologous lymphocytes. Nine patients were treated with CD19 CAR-T cells, and 12 were treated with CD19/CD22 CAR-T cells. After assessment on day 28 after CAR-T therapy, 95.2% of the patients achieved complete remission, with an MRD-negative remission rate of 75%. Nineteen patients developed grade 0–2 cytokine release syndrome (CRS) and 2 patients suffered grade 3 CRS, all cases of which resolved after treatment. All patients underwent allo-HSCT after CAR-T therapy. The median time from CAR-T therapy to allo-HSCT was 63 (38-114) days. Five patients experienced relapse after CAR-T therapy, including four with hematologic relapse and one with molecular relapse. The 3-year overall survival (OS) rates in the ABL1 and JAK-STAT groups were (83.3±15.2) % and (66.6±17.2) %, respectively ( P=0.68) . The 3-year relapse-free survival (RFS) rates were (50.0±20.4) % and (55.6±15.4) % in the ABL1 and JAK-STAT groups, respectively. There was no significant difference in 3-year OS or RFS between the two groups. Conclusions:CAR-T therapy followed by allo-HSCT leads to rapid remission in most patients with Ph-ALL and prolongs leukemia-free survival.

CONCLUSIONS The established HPLC-MS/MS method is simple， sensitive and can be used for the determination of caffeine and its three metabolites in urine samples of AOP.

ObjectiveTo investigate the principle and scientific connotation of Euodiae Fructus（EF） processed with Glycyrrhizae Radix et Rhizoma（Gly） by comparing the effects of unprocessed products of EF（UEF） and processed products of EF with the different proportions of Gly（GEFs） at toxic doses on oxidative stress and autophagy in the liver of mice. MethodSeventy mice were randomly divided into 7 groups， namely the control group， the UEF group， the group of the processed products of EF without Gly（PEF） and 4 groups of GEFs（the mass ratios of EF to Gly were 100∶3， 100∶6， 100∶12 and 100∶24， respectively， hereinafter referred to as the processed products of EF with the mass ratios of 100∶3， 100∶6， 100∶12 and 100∶24 of Gly）. The mice were given purified water， the decoction of UEF， PEF and GEFs by gavage at a dose of 30 g·kg^-1. PEF and GEFs were prepared according to the method under EF in the 2020 edition of Chinese Pharmacopoeia. Levels of alanine aminotransferase（ALT） and aspartate aminotransferase（AST） were determined by ultraviolet-visible spectrophotometry， hematoxylin-eosin（HE） staining was used to evaluate the pathological changes of liver tissue， the level of reactive oxygen species（ROS） was detected by fluorescence method， the mRNA expression of heme oxygenase-1（HO-1）， quinone oxidoreductase-1（NQO1）， glutathione-S-transferase 1（GSTA1）， Kelch-like epichlorohydrin-associated protein 1（Keap1） and p62 were measured by Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， western blot was used to detect the protein expression of phosphorylated mammal target of rapamycin（p-mTOR）， phosphorylated ribosomal p70 S6 protein kinase（p-p70S6K）， p62， microtubule-associated protein 1 light chain 3Ⅰ（LC3Ⅰ） and LC3Ⅱ. ResultCompared with the control group， after 7 d of administration， the increase in body mass of mice in the UEF group began to slow down and the difference gradually increased， and the liver body index significantly increased（P<0.01）， pathomorphological observation showed that the structure of hepatic lobules was disordered， and local hepatic sinuses were narrowed or disappeared， and there were inflammatory infiltration and local bleeding， the levels of ALT and AST in serum and ROS in liver tissue were significantly increased（P<0.01）， and the expressions of Keap1， HO-1， NQO1， GSTA1， p62 mRNA and p-mTOR， p-p70S6K， p62 protein in liver tissue were significantly decreased（P<0.01）， and LC3Ⅱ/LC3Ⅰ was significantly increased（P<0.01）. Compared with the UEF group， the body mass of mice increased， and the liver body index， the levels of ALT and AST in serum， and the level of ROS in liver tissue all decreased in the groups of PEF and GEFs. Among these groups， only the liver lobules in GEF（100∶6） group were intact， and the size of liver sinuses was close to that in the control group. The mRNA expressions of Keap1， HO-1， NQO1， GSTA1 and p62 in liver tissue showed an overall upward trend in the groups of PEF and GEFs. Among these groups， only the ones of the above mRNA in the GEF（100∶6） group had a significant increase（P<0.05， P<0.01）. The protein expressions of p-mTOR， p-p70S6K， p62 and LC3Ⅱ/LC3Ⅰ had a callback in the groups of PEF and GEFs， of which the protein expressions of p-mTOR， p-p70S6K and LC3Ⅱ/LC3Ⅰ in the GEF（100∶6） group and the expression of p62 protein in the GEF（100∶24） group had the largest callback. Except for p-mTOR protein， other protein expressions were statistically significant（P<0.05， P<0.01）. ConclusionThe hepatotoxicity of EF is closely related to its ability to induce oxidative stress， which leads to pathological autophagy and hepatocyte damage. This ability can be reduced by the processing with different proportions of Gly， especially the ratio of 100∶6.

ObjectiveTo explain the scientific connotation of Morindae Officinalis Radix （MOR） processed by Glycyrrhizae Radix et Rhizoma （Gly） by comparing the effect of raw products of MOR and processed products of MOR with different proportions of Gly （GMOs） on the improvement of renal function and hypothalamic-pituitary-gonadal （HPG） axis， the protein expression of Wnt/β-catenin and transforming growth factor-β₁ （TGF-β₁）/Smad signal pathways in kidney Yang deficiency model rats induced by adenine. MethodGMOs were prepared according to method under MOR in 2020 edition of Chinese Pharmacopoeia. Rat model of kidney Yang deficiency was established by intragastrical administration of adenine， levels of follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂） and testosterone （T） were measured by enzyme-linked immunosorbent assay （ELISA）. Levels of urea nitrogen （BUN） and serum creatinine （SCr） were measured by spectrophotometry， hematoxylin-eosin （HE） staining was used to evaluate the pathological changes of kidney， testis and epididymis. Immunohistochemistry （IHC） was used to analyze the protein expression of E-cadherin， α-smooth muscle actin （α-SMA）， Wnt2b， β-catenin， Smad1 and Smad4. ResultMOR processed with 100∶6 and 100∶12 proportions of Gly （short for GMO/100∶6 and GMO/100∶12） had the most obvious improvement on the body posture of kidney Yang deficiency model rats. GMO/100∶12 had the best effect on reducing the levels of BUN， SCr， FSH， LH and the ratio of E₂/T. GMO/100∶6 and GMO/100∶12 had the best effect on regulating the protein expression of E-cadherin， α-SMA， Wnt2b， β-catenin， Smad1 and Smad4. ConclusionGMO/100∶6 and GMO/100∶12 have the a good effect on the improvement of renal function and HPG axis in kidney Yang deficiency model rats induced by adenine， which is related with the fact that they can regulate Wnt/β-catenin pathway in renal and testicular tissue and TGF-β₁/Smads pathway in testicular tissue.

Objective To analyze the loss coefficient of bivalent live attenuated oral polio vaccine（bOPV) in Hongshan District, and understand the causes and influencing factors, and to provide a basis for scientifically formulating vaccine use plans and regulating vaccine management. Methods Using the data of Hubei Province Immunization Planning Information System and Hongshan District Vaccination Storage and Management System, a special questionnaire was designed to understand the vaccination and use of bOPV in various immunization units in Hongshan District. A descriptive statistical analysis method was used to calculate the loss coefficient. Results The bOPV loss coefficient of 25 vaccination units in Hongshan District was 1.69. The difference of the loss coefficient between the out-patient clinics of the District Health and Family Planning Committee（1.35）and the community clinics undertaken by large hospitals (2.01）was statistically significant. The difference of the loss coefficient between the inoculation once a week（1.57）and 2-6 times per week（1.94）was statistically significant. In terms of vaccine-disabled time, the two groups of <4 hours and >4 hours had different calculated loss coefficients 1.86 and 1.61, respectively, and the difference was statistically significant. Multivariate regression analysis of the factors related to the loss coefficients found that different outpatient attributes had a greater impact on the loss coefficient than the inoculation cycle and the number of inoculation stations. The loss coefficient for 2016 and 2017 was 2.09 and 1.75, respectively. The difference was statistically significant. Conclusion The management and use of live attenuated bivalent polio vaccine in Hongshan District was relatively standardized. The vaccine loss can by further reduced by strengthening supervision and assessment, setting up centralized vaccination and standardizing publicity and training.

Objective: To investigate the expressions of miR-144 and lncRNA DNAJC3-AS1 in breast cancer tissues and their effects on chemo-resistance of breast cancer MCF-7 cells. Methods: A total of 196 pairs of breast cancer tissues and corresponding adjacent normal tissues collected between January, 2012 and December, 2016 in Department of Oncology, 3201 Hospital were used for this study. The relative expressions of DNAJC3-AS1, DNAJC3 and miR-144 in collected tissues were determined using qPCR, and their impact on the survival of BC patients was also analyzed. The targeted binding relationship between DNAJC3-AS1 and miR-144 was verified by Luciferase reporter gene assay. DNAJC3-AS1 over-expression plasmid and miR-144 mimics were transfected into MCF-7 cell lines respectively, and qPCR was used to verify the transfection efficiency. The effects of DNAJC3-AS1 and miR-144 overexpression on proliferation and cisplatin sensitivity of MCF-7 cells were verified by CCK-8 assay. Results: DNAJC3-AS1 and its host gene DNAJC3 were highly expressed in BC tissues (all P<0.01), and these two were positively correlated (r=0.451, P<0.01); in addition, patients with high expressions of DNAJC3-AS1 and DNAJC3 had a shorter survival period (all P<0.01). miR-144 was highly expressed in BC tissues (P<0.01) and negatively correlated with DNAJC3-AS1 (r=-0.524, P<0.01). The average over-expressionfold for DNAJC3-AS1 was 13.47 (P<0.01), while the fold for miR-144 was 20.27 (P<0.01). Bioinformatics analysis and fluorescence reporter gene assay confirmed that DNAJC3-AS1 could specifically bind to miR-144. MCF-7 cell lines over-expressing DNAJC3-AS1 and miR-14 were successfully constructed; compared with control group, cells in DNAJC3-AS1 over-expression group exhibited significantly enhanced proliferation and reduced cisplatin-sensitivity (all P<0.01), while the cells in miR-144 over-expression group showed significantly enhanced drug sensitivity (P<0.01). Conclusion: miR-144 and lncDNAJC3-AS1 were highly expressed in BC tissues, miR-144 promotes cisplatin sensitivity of BC MCF-7 cells through targeting DNAJC3-AS1.

Objective: To investigate the short-term efficacy and toxicity of bevacizumab combined with DP or rh-endostatin（recombinant human vascular endostatin injection）combined with DP in locally advanced EGFR wild-type non-small cell lung cancer (NSCLC). Methods: Seventy-two patients with treatment of locally advanced EGFR wild-type NSCLC admitted to the Department of Respiratory Medicine of Zhongshan Hospital Affiliated to Guangdong Medical University from January 2014 to January 2017 were divided into bevacizumab group (34 cases) and rh-endostatin group (38 cases) according to the random number method. The former group was treated with bevacizumab combined with docetaxel and cisplatin, while the latter was treated with rh-endostatin combined with docetaxel and cisplatin. According to RECISIT 1.1 standard, the changes of lesion size before and after treatment in two groups were evaluated. Serum levels of vascular endothelial growth factor (VEGF), carcinoembryonic antigen (CEA), cytokeratin 21-1 fragment (CYFRA21-1), squamous cell carcinoma antigen (SCC) were measured. The adverse reactions during treatment were also evaluated. Results: In bevacizumab group, patients with CR, PR, SD, PD, DCR and ORR were 2 cases, 12 cases, 15 cases, 5 cases, 41.18% and 85.29%, respectively. In rh-endostatin group, patients with CR, PR, SD, PD, DCR, ORR were 2 cases, 16 cases, 14 cases, 6 cases, 47.37% and 84.21%, respectively. The DCR in rh-endostatin group was significantly higher than that in bevacizumab group (P<0.05).The serum levels of VEGF and CEAin rh-endostatin group decreased more obvious than those in bevacizumab group (all P<0.05). The incidence of gastrointestinal reaction, skin reaction and cardiac toxicity in rh-endostatin group was higher than that in bevacizumab group, while the incidence of bleeding in bevacizumab group was higher than that in rh-endostatin group (all P<0.05). Conclusion: In patients with locally advanced EGFR wild-type NSCLC, rh-endostatin combined with DP regimen is better than bevacizumab combined with DPregimen. In clinical practice, corresponding treatment regimen can be selected according to different characteristics of patients, so as to minimize the toxic reaction during treatment and avoid clinical risk.

Objective To explore the CT manifestations of primitive neuroectodermal tumor (PNET) of adrenal gland,aiming to increase the cognition on this disease.Methods The CT manifestations of 7 patients who were pathologically diagnosed with adrenal gland PNET were analyzed retrospectively.Results The age of patients was 24-63 years old,with average age of (47.6±13.7) years,including 6 females and 1 male.Location of PNET:4 in left adrenal gland and 3 in right adrenal gland.Clinical manifestations:3 cases had upper abdominal distension,2 cases suffered from pain of waist and back,1 case was discovered in physical examination and another 1 had fever.No abnormality was found in laboratory and endocrinological examinations.After operation,4 cases had recurrence and 2 had distant metastasis.During follow-up,6 patients died and only 1 still alive.CT showed that the tumor,whose maximum diameter was 10.1-19.4 cm,was elliptic or lobulated in shape.The tumor was clear in boundary in 2 patients,but was unclear in boundary and involved adjacent organs in 5 patients.The plain scanning showed equidensity or slightly low density,complicated with necrosis and cystic lesions without calcification.The enhanced scanning suggested progressive uneven enhancement,with multiple interatrial septum-like changes and latticed enhancement inside.Conclusion CT manifestations of adrenal gland PNET can prompt the diagnosis,pathological examination is still required for confirmation.CT can accurately describe the internal structures,adjacent relationship and the metastasis of tumors.
