Objective:To investigate the quality of life of lymphoma patients receiving different treatment methods under unaccompanied nursing care mode.Methods:A cross sectional study was conducted. A total of 374 lymphoma patients who received chemotherapy, hematopoietic stem cell transplantation, chimeric antigen receptor T (CAR-T) cell therapy, or other targeted immunotherapy under unaccompanied nursing care mode in the First Affiliated Hospital of Soochow University from January 2023 to December 2023 were selected. The basic information of patients was collected through a questionnaire, and the Cancer Rehabilitation Evaluation System-Short Form (CARES-SF) was used to score the quality of life of patients from physiological, psychosocial, the relationship with healthcare professionals, marital relations, sexual function, and the overall health aspects. The higher score indicated the worse quality of life. The differences in quality of life among patients stratified by the different treatment methods and high-intensity treatment (CAR-T cell therapy or transplantation) and low-intensity treatment (other treatment methods) under unaccompanied care mode were compared.Results:Among the 374 patients, 62 received autologous hematopoietic stem cell transplantation, 13 received allogeneic hematopoietic stem cell transplantation, and 36 received CAR-T cell therapy. There were no statistically significant differences in the dimensions of CARES-SF and the overall health aspects scores between the transplantation treatment group and the non-transplantation treatment group (all P > 0.05). For non-transplant patients, there were no statistically significant differences in the dimensions of CARES-SF and overall health aspects scores between the CAR-T cell treatment group and the non-CAR-T cell treatment group (all P > 0.05); for transplant patients, the physiological dimension score [ M ( IQR)] of CARES-SF in the allogeneic hematopoietic stem cell transplantation group was higher than that in the autologous hematopoietic stem cell transplantation group [16 points (9 points) vs. 8 points (9 points)], and the difference was statistically significant ( Z = -2.30, P = 0.021), but there were no statistically significant differences in the scores of other dimensions and overall health aspects (all P > 0.05). There were no statistically significant differences in the dimensions of CARES-SF and overall health aspects scores in the high-intensity treatment group and the low-intensity treatment group (all P > 0.05). Conclusions:There is no significant difference in the quality of life of lymphoma patients receiving different treatment methods under the unaccompanied care mode, while lymphoma patients receiving high-intensity treatment and low-intensity treatment have similar life quality. Lymphoma patients receiving high-intensity treatment may benefit more from the unaccompanied care mode.

Cordyceps sinensis(C.sinensis)is a widely used and highly valuable traditional Chinese medicine.Several dipeptides have been detected in C.sinensis,but current scientific knowledge of its chemical makeup remains limited.In this study,an improved approach that integrates offline two-dimensional liquid chromatography(2D LC)separation,precursor ion list,library screening,and diagnostic ion filtering was established to systematically screen and characterize dipeptides in C.sinensis.Offline 2D LC integrating hydrophilic interaction LC and reverse phase separations was established to eliminate interference and identify the target dipeptides.A library containing the potential 400 dipeptides was created,and a precursor ion list with all theoretical precursor ions was adopted to trigger the MS/MS scan with high sensitivity.To identify dipeptides,the type and connection sequence of amino acids were determined according to the product ions.Ile and Leu residues were differentiated for the first time according to the characteristic ion at m/z 69.07.Ultimately,170 dipeptides were identified or tentatively characterized from C.sinensis,and most are reported for the first time in this species herein.In addition,the identified dipeptides were also applied for discrimination among the three Cordyceps species,and 11 markers were identified.The obtained results provide a deeper understanding of the chemical basis of C.sinensis.

Objective:To investigate the effect and prognostic factors of rituximab-containing chemotherapy regimen in treatment of patients with mantle cell lymphoma (MCL).Methods:The clinical data of 56 patients aged ≤65 years in the First Affiliated Hospital of Soochow University from June 2007 to November 2018 were retrospectively analyzed. Rituximab-containing chemotherapy regimen was used, and the effects of clinical features, treatment regimen and biological indexes on overall survival (OS) and progression-free survival (PFS) were observed.Results:The median age of 56 patients was 57 years old, including 43 males and 13 females. Among these cases, 24 patients received R-CHOP chemotherapy regimen; 29 patients received cytarabine-containing chemotherapy regimen, including R-hyper CVAD/R-MA regimen used in 15 patients and R-CHOP alternating with R-DAHP regimen used in 14 patients; and 3 patients received other treatment regimens. Among 56 patients, 19 patients received autologous hematopoietic stem cell transplantation (ASCT) consolidation therapy. The median OS time was 74 months, 2-year OS rate was 83.8%, 3-year OS rate was 70.9%, 2-year PFS rate was 72.0% and 3-year PFS rate was 49.7%. International prognostic index (IPI) high-risk and receiving ASCT or not during the treatment were independent influencing factors of OS and PFS in MCL patients. The overall response rate (ORR) in cytarabine-containing regimen group was higher compared with that in R-CHOP regimen group (93.1% vs. 83.3%), and there was no statistically significant difference ( χ2=0.465, P=0.495). In addition, there were no significant differences between two groups in both OS ( χ2=0.291, P=0.590) and PFS ( χ2=0.912, P=0.339). ASCT consolidation prolonged the median OS time (72 months vs.124 months, χ2=3.973, P=0.040) and the median PFS time (34 months vs. 90 months, χ2=3.984, P=0.046) in MCL patients achieving remission after induction therapy. Among patients in simplified MCL IPI (sMIPI) score middle-high risk group, compared with those not receiving ASCT, patients receiving ASCT therapy could obtain better OS and PFS (OS: χ2=5.037, P=0.025; PFS: χ2=6.787, P=0.009); among patients of sMIPI score low risk, there were no statistically significant differences in OS and PFS between the group receiving ASCT and not (all P > 0.05). Conclusions:Cytarabine-containing chemotherapy regimen has no predicatively satisfactory value in improving the prognosis and survival for MCL patients. For MCL patients who have achieved remission after reduction therapy and those in sMIPI score middle-high risk group, ASCT consolidation therapy can improve the prognosis and can be taken as the first-line consolidation treatment in young patients.

Objective:To examine the efficacy of haploidentical stem-cell transplantation (haplo-SCT) for patients with refractory relapsed (R/R) non-Hodgkin lymphoma (NHL) by comparing with those contemporaneously undergoing HLA-matched SCT in myeloablative conditioning settings.Methods:Between January 2006 and December 2018, a total of 151 patients undergoing haplo-SCT ( n=81) or HLA-matched SCT ( n=70, sibling or unrelated) were enrolled. Median age of alloSCT was 30(5-59) years. And 150 patients received myeloablative conditioning (MAC) consisting of total body irradiation (12 Gy) plus cyclophosphamide or busulfan plus cyclophosphamide. Only one case had reduced intensity conditioning (RIC) with R-FBA (fludarabine, busulfan & cytarabina). It was followed by an infusion of granulocyte-colony stimulating factor-primed bone marrow (G-BM) and/or peripheral blood stem cells without in vitro T cell depletion. In haplo-SCT and HLA-matched unrelated donor for SCT, GVHD prophylaxis consisted of antithymocyte globulin, cyclosporine A, mycophenolate mofetil and a short course of methotrexate. Clinical efficacy, hematopoietic reconstitution and transplant-related complications were retrospectively analyzed. Results:Among them, 146(96%) patients engrafted with a median time to neutrophil and platelet recovery of 12 and 15 days respectively. During a median follow-up period of 19 months, 66 of them survived (43.7%) and 67 (44.4%) died (39 disease recurrence, 27 transplantation-related mortality). Between haplo-SCT and HLA-matched SCT groups, progression-free survival (PFS) rate was 49.4% and 50.5% ( P=0.577); overall survival (OS) rate 56.7% and 57.4% respectively ( P=0.963). The cumulative incidences of relapse (CIR) were 36.6% and 37.7% ( P=0.836) and those of cumulative incidences of non-relapse mortality (NRM) 22.0% and 24.7% ( P=0.530). And the cumulative incidences of chronic GVHD were 42.3% and 39.6% ( P=0.46) respectively. Conclusions:No inter-group difference exists in each major HSCT endpoint. Multivariate analysis reveals that occurrence of grade Ⅲ-Ⅳ aGVHD has a significantly worse prognosis. And primary chemorefractoriness is a strongest relapsing factor.

Objective: To study the value of unmethylated cytosine guanine dinucleotide oligodeoxynucleotide (DSP30) and IL-2 in the conventional cytogenetic (CA) detection of the chromosomal aberrations in chronic lymphocytic leukemia (CLL) . Methods: Bone marrow or peripheral blood cells of CLL patients were cultured with DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Fluorescence in situ hybridization (FISH) was performed in 85 patients. CA results were compared with data obtained by FISH. Results: Among 89 CLL patients, the success rate of chromosome analysis was 94.38% (84/89) . Clonal aberrations were detected in 51 patients (51/84, 60.71%) . Of them, 27 (27/51, 52.94%) were complex karyotype. Among 85 CLL patients tested by FISH, chromosomal abnormalities were detected in 74 (74/85, 87.06%) patients, of which 2 (2/74) patients were complex karyotypes, accounting for 2.70%. Of the 85 CLL patients examined by FISH, 50 had abnormal karyotype analysis, 30 had normal karyotype, 5 failed to have chromosome analysis. Among them, 25 cases showed clonal aberrations by FISH assay but normal by CA, and 4 cases were normal by FISH but displayed aberrations in chromosome analysis, and totally 78 (91.76%) cases with abnormality detected by the combination of the two methods. The frequency of 13q- abnormality detected by FISH was significantly higher than that by CA analysis (69.41%vs 16.67%, P<0.001) , while the frequency of 11q-,+12 and 17p- detected by two methods showed no significant difference (P>0.05) . The detection rate of complex abnormalities in conventional karyotype analysis was higher than that in FISH (50.98%vs 2.70%) . In addition, 11 low-risk and 9 intermediate-risk patients according to FISH results showed complex karyotype by cytogenetics, and were classified into high-risk cytogenetic subgroup. Conclusion DSP30 and IL-2 are effective in improving the detection rate of CA in CLL patients (60.71%) and CA is more effective to detect complex karyotype. However, FISH had a higher overall abnormality detection rate (87.06%) than CA, especially for 13q-. The combination of CA and FISH not only enhanced the detection rate of clonal aberrations to 91.76%, but also provided more precise prognosis stratification for CLL patients, thus to provide more information for clinical implication.

Objective: To explore the effect of BMI and waist circumference on diabetes of adults. Methods: After excluding participants with heart disease, stroke, cancer and diabetes at baseline study, 53 916 people aged 30-79 in the China Kadoorie Biobank (CKB) study from Tongxiang city of Zhejiang province were recruited. Cox regression model was used to estimate the hazards ratios (HR) for the associations of baseline BMI and waist circumference with incident diabetes. Results: Among 391 512 person-years of the follow-up program between 2004 and 2013 (median 7.26 years), a total of 944 men and 1 643 women were diagnosed as having diabetes. Compared to those with normal weight, after adjusting for known or potential factors, HR of both overweight and obesity in men for incident diabetes appeared as 2.72 (95%CI: 2.47-2.99) and 6.27 (95%CI: 5.33-7.36), respectively. The corresponding figures in women were 2.19 (95%CI: 2.04-2.36) and 3.78 (95%CI: 3.36-4.26). Compared to those with normal waist circumference, after adjusting for known or potential factors, HR of Ⅰgrade andⅡgrade in men for diabetes were 2.56 (95%CI: 2.22-2.95) and 4.66 (95%CI: 4.14-5.24), respectively. The corresponding figures in women were 1.99 (95%CI: 1.80-2.21) and 3.16 (95%CI: 2.90-3.44), respectively. Conclusions: Overweight, obesity and central obesity were all associated with the increased incident of diabetes. Strategies on diabetes prevention should include not only losing weight, but reducing waist circumference as well.

Objective To study the autophagy of human glioblastoma SF295 cells induced by sponge-derived triterpenoid Stellittin B (Stel B) and to discuss the related mechanism. Methods The proliferation inhibitory activity of Stel B on SF295 cells was studied by WST-8 assay. The autophagy effect induced by Stel B on SF295 cells was evaluated bya variety of experimental techniques, including MDC staining, Western Blot assay, and mRFP-GFP-LC3 plasmid transfection method.The activity of Stel B on the representative signal proteins in PI3K/Akt/mTOR pathway in SF295 cells was examined by Western Blot. The anti-tumor activity of Stel B was detected by WST-8 assay after blocking autophagy by autophagy inhibitor chloroquine. Results Stel B could significantly inhibit the proliferation of SF295 cells with IC50 value as 0.026 μmol/L. Plenty of autophagosome was found in Stel B treated A549 cells by MDC staining. The expression of autophagy marker proteins including LC3B-II increased. The confocal microscopy results showed that Stel B promoted autophagosome forming and inhibitedthe fusion of autophagosome with lysosome. The Western Blot results showed that Stel B inhibited the expression of PI3K-p110 protein in SF295 cells and decreased the phosphorylation level of Akt and mTOR.The inhibitory effects of Stel B with different concentrations on SF295 cells were all enhanced by the inhibition of autophagy with chloroquine, and the differences were statistically significant (all P<0.05). Conclusion Stel B can induce SF295 cells autophagy via blocking PI3K/Akt/mTOR pathway. This autophagy effect is beneficial to the survival of SF295 cells. The antitumor activity of Stel B can be enhanced by a combination of autophagy inhibitors.

Cordyceps is a famous traditional Chinese medicine (TCM) that has been used in China for hundreds of years. In the present study a multi-column liquid chromatography (MC-LC) system was developed for the qualitative analysis of macromolecules and micromolecules in Cordyceps. The MC-LC system includes a size exclusion pre-column, a size exclusion column (SEC) and a reversed phase column (RP) which were controlled by column-switching valves. The sample was separated by the size exclusion pre-column into two fractions (macromolecules and micromolecules). These fractions were further separated on SEC and RP columns, respectively. A diode array detector (DAD) and a mass spectrometer (MS) were used to detect the components. This MC-LC method was utilized for analysis of Cordyceps samples. Two macromolecular peaks and 15 micromolecular peaks were found in Cordyceps, and 11 of the micromolecular peaks were identified as adenosine-5'-monophosphate (AMP), phenylalanine, uridine, hypoxanthine, inosine, guanine, guanosine, deoxyadenosine-5'-monophosphate (dAMP), adenosine, adenine and cordycepin (or its isomer). This method is useful for quality control of Cordyceps.

A HPLC-QTOF MS method was established for analysis of components in Ophiocordyceps sinensis . The HPLC analysis was performed on an Agilent Zorbax SB Aq (150 mmí4.6 mm, 5 μm) with gr adient elution (5 mmol·L-1 ammonium acetate aqueous solution-acetonitrile), flow rate was 0.8 mL·min-1 and detection wave-length was 260 nm. The developed method was successfully applied in analysis of three different samples in-cluding O. sinensis, Hirsutella sinensis ( anamorph of O.sinensis) and Cordyceps militaris. Nine compounds were i-dentified in both O.sinensis and H.sinensis, which eight compounds were identified in C.militaris.

A HPLC method for simultaneous determination of uridine, inosine, guanosine, adenosine and cordycepine
in Cordyceps sinensis was developed. The sample solution was prepared with 0.5% phosphoric acid solution by ultrasonic extraction. The separation was performed on a ZORBAX SB-AQ (150 mmí4.6 mm, 5 μm)column with gradient elution by 0.1% formic acid solution and acetonitrile, with column temperature 30℃, at a flow rate of 0.8 mL/min, and detected at wavelength of 260 nm. The result of method validation showed that the developed method had high accuracy and good repeatability. This method has been successfully applied for analysis of 5 kinds of nucleosides in different parts of C. sinensis. The results indicated that content of nucleosides in stroma is higher than that in insect body and whole C. sinensis.
