摘要
It was a retrospective study. The patients with type 2 diabetes mellitus (T2DM) who underwent renal biopsy in the Department of Nephrology, the First Affiliated Hospital of Xi'an Jiaotong University from 2015 to 2021 were enrolled to analyze the pathological and clinical manifestations of kidney. There were 483 patients enrolled, including 136 patients who had no history of diabetes mellitus, newly diagnosed as T2DM according to an oral glucose tolerance test. The age was (52.80±13.13) years old. There were 337 males (69.77%). Based on the renal biopsy, the patients were classified as diabetic kidney disease (DKD, 22.15%, 107/483), DKD+non-diabetic kidney disease (NDKD)(6.63%, 32/483), and NDKD (71.22%, 344/483). Membranous nephropathy was the most common pathology in patients with NDKD (40.41%, 139/344) and DKD+NDKD (34.38%, 11/32). In the 136 newly diagnosed T2DM patients, there were 3 patients (2.21%) with DKD, 2 patients (1.47%) with DKD+NDKD, and 131 patients with NDKD (96.32%). The proportions of DKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 10.53% (6/57), 25.00% (16/64), 26.53% (26/98), 41.56% (32/77) and 47.06% (24/51), respectively. The proportions of DKD+NDKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 3.51% (2/57), 3.13% (2/64), 10.20% (10/98), 9.09% (7/77) and 17.65% (9/51), respectively. Multivariate logistic regression analysis results showed that, the duration of diabetes history ( OR=1.130, 95% CI 1.057-1.208, P<0.001), diabetes retinopathy ( OR=12.185, 95% CI 5.331-27.849, P<0.001), urinary red blood cell count ( OR=0.987, 95% CI 0.974-0.999, P=0.039), glycosylated hemoglobin ( OR=1.482, 95% CI 1.119-1.961, P=0.006) as well as hemoglobin ( OR=0.973, 95% CI 0.957-0.990, P=0.001) were independently correlated with DKD. The proportions of DKD and DKD+NDKD increase with the prolongation of diabetes history. Membranous nephropathy is the most common pathology in NDKD and DKD+NDKD patients. Even in patients newly diagnosed with T2DM, it is necessary to screen for DKD. The duration of diabetes history, diabetes retinopathy, urinary red blood cell count, glycosylated hemoglobin and hemoglobin may be used to identify DKD from NDKD.

【Objective】 To study the effects of miR-30e-5p from bone marrow mesenchymal stem cell-derived exosomes(BMSC-exos) on high glucose (HG)-induced HK-2 cell pyroptosis and explore an alternative strategy to manage diabetic kidney disease (DKD). 【Methods】 BMSC-exos were isolated and internalized into HK-2 cells treated with HG to measure viability and cytotoxicity. The secretion of IL-1β and IL-18 was measured by ELISA. Pyroptosis was assessed by flow cytometry. The levels of miR-30e-5p, IL-1β, and IL-18 were measured. The expression of pyroptosis-associated cytokine proteins was determined. 【Results】 BMSC-exos decreased LDH, IL-1β, and IL-18 secretion and inhibited the expression of the pyroptosis-related factors (IL-1β, caspase-1, GSDMD-N, and NLRP3) in HG-induced HK-2 cells. Moreover, miR-30e-5p depletion in BMSC-exos promoted HK-2 cell pyroptosis. 【Conclusion】 BMSC-derived exosomal miR-30e-5p inhibits caspase-1-mediated pyroptosis in HG-induced HK-2 cells, which might provide a new strategy for treating DKD.

Objective:To assess the performance of liver and spleen stiffness measured by MR elastography (MRE) and their combined model in diagnosing liver fibrosis.Methods:From November 2018 to November 2019, 104 patients with chronic liver disease were prospectively enrolled in Beijing Friendship Hospital, all patients underwent MRE scans. Liver and spleen stiffness were measured from MRE elastograms. Liver biopsy was used to identify fibrosis stage (F0—F4). The differences among different fibrosis stages were analyzed by one-way ANOVA or independent samples t test. The Spearman rank correlation analysis was used to evaluate the correlation with fibrosis stages. Liver and spleen stiffness combined model was established by logistic regression. The ROC curve was used to evaluate the performance of the liver, spleen stiffness and combined model in staging fibrosis (≥F1), significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F4).The area under the ROC curve(AUC) was compared using Delong test. Results:The liver and spleen stiffness both showed significant differences among the 5 fibrosis stages ( F=64.058, 32.890, both P<0.001). The liver and spleen stiffness were positively associated with fibrosis stage ( r s=0.89, 0.69, both P<0.001). The AUC of liver stiffness in staging ≥F1, ≥F2, ≥F3 were 0. 91, 0.97, 0.93, respectively. The corresponding AUCs of the spleen stiffness were 0.81, 0.82, 0.85, respectively, which were statistically lower than those of liver stiffness ( Z=2.283, 4.085, 2.314, P=0.022,<0.001, 0.021). In diagnosing F4, the AUCs of liver and spleen stiffness were both 0.95. The AUCs of the liver and spleen combined model were 0.92, 0.97, 0.93, 0.96 in diagnosing ≥F1, ≥F2, ≥F3 and F4, with no significantly differences from liver stiffness (all P>0.05). Conclusions:The liver stiffness measured with MRE have better diagnostic performance than spleen stiffness in staging fibrosis. Parameters combined model slightly improves diagnostic value but without significant difference with liver stiffness in staging early fibrosis. Spleen stiffness evaluation is feasible in detecting cirrhosis.

Objective@#To evaluate the prognostic value of 18F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in patients with diffuse large B cell lymphoma (DLBCL) undergoing autologous hematopoietic stem cell transplantation (auto-HSCT).@*Methods@#Forty-eight patients with DLBCL treated at Peking University Cancer Hospital between November 2010 and December 2014 were assessed. All patients underwent PET/CT scanning prior to or after auto-HSCT. Correlation analysis was done based upon patients characteristics, PET/CT scan results and survival.@*Results@#①Among 48 patients, 27 was male, 21 female, median age was 43 (17-59) years old. ② Patients with negative pre-auto-HSCT PET/CT assessment demonstrated significantly better 3-year progression free survival (PFS) (87.1% vs 53.3%, χ2=7.02, P=0.019) and overall survival (OS) (90.3% vs 60.0%, χ2=6.51,P=0.022) than patients with positive pre-auto-HSCT PET/CT assessment. Three-year PFS (94.1% vs 30.0%, χ2=22.75, P=0.001) and OS (97.1% vs 40.0%, χ2=21.09, P=0.002) were also significantly different between patients with negative and positive post-auto-HSCT PET/CT assessment. ③ Multivariate analysis indicated a significant association of PFS (HR=13.176, P=0.005) and OS (HR=20.221, P=0.007) with post-auto-HSCT PET/CT assessment. Number of prior treatment regimens was associated with PFS (HR=10.039, P=0.040). ④ Harrell’s C index revealed that the value of combined use of number of prior treatment regimens and post-auto-HSCT PET/CT assessment was superior to either one used alone in PFS (Harrell’s C values were 0.976, 0.869 and 0.927 in combined use, number of prior treatment regimens and post-auto-HSCT PET/CT assessment, respectively), and the combined use of ECOG performance status and post-auto-HSCT PET/CT assessment significantly increased the Harrell’s C index in OS (Harrell’s C values were 0.973, 0.711 and 0.919 in combined use, ECOG performance status and post-auto-HSCT PET/CT assessment, respectively).@*Conclusions@#Post-auto-HSCT PET/CT assessment is the main predictor of outcomes in DLBCL patients receiving auto-HSCT. Combined use of post-auto-HSCT PET/CT assessment and number of prior treatment regimens and ECOG performance status is a better prognostic tool in patients with DLBCL undergoing transplantation.

Objective@#To evaluate the clinical characteristics and survival outcomes of patients with de novo grade 3 or transformed follicular lymphoma (FL).@*Methods@#Fifty-two patients treated at Peking University Cancer Hospital between January 2009 and September 2017 were assessed, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. Baseline characteristics, survival and prognostic factors were analyzed.@*Results@#① Twenty-six male and 26 female patients were enrolled, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. ②The 3-year progression-free survival (PFS) and overall survival (OS) for the entire cohort were 56.0% and 80.6%, respectively. Patients with international prognostic index (IPI) score 0-1 demonstrated significantly better 3-year PFS (80.3% vs 20.1%; t=18.902, P<0.001) and OS (95.7% vs 57.0%; t=10.406, P<0.001) than patients with IPI score 2-3. Three-year PFS (94.1% vs 37.2% vs 25.2%; P=0.002) and OS (100.0% vs 76.0% vs 59.8%; P=0.020) were also significantly different among patients with FLIPI 1 score 0-1, 2, ≥3. FLIPI 2 score was also identified as a prognostic factor for 3-year PFS (68.4%, 0, 0; P=0.001) and OS(87.5%, 76.2%, 0; P=0.003). ③Multivariate analysis indicated a significant association of PFS (HR=3.536, P=0.015) and OS (HR=15.713, P=0.015) with IPI. FLIPI 2 was associated with OS (score 0-1, HR=0.078, P=0.007; score 2, HR=0.080, P=0.022).@*Conclusion@#De novo grade 3 or transformed FL might be a group of curable disease with current treatment strategies. IPI is still a prognostic tool in this scenario.

OBJECTIVE:To study the relationship of GSTP 1(rs1695)(simply as GSTP 1)gene polymorphism with the hematological toxicity in autologous hematopoietic stem cell transplantation(AHSCT)patients who used CBV regimen (cyclophosphamide,carmustine,etoposide). METHODS:A total of 83 AHSCT patients receiving CBV regimen were retrospective analyzed in our hospital during Apr. 2015-Jun. 2017. The gene polymorphism of GSTP 1 A313G was detected by fluorescence staining in situ hybridization. The hematological toxicity and the incidence of agranulocytosis fever,the implantation time of leukocyte,neutrophils and platelet were analyzed statistically. The relationship of GSTP 1 with above indexes were analyzed. RESULTS:Among 83 patients,gene variation was observed in one gene loci at least of 28 patients(33.73%).The gene frequency of A allele was 81.3%,while that of G allele was 18.7%. The reduce time of Ⅳ grade leukopenia,Ⅳ grade neutropenia and Ⅳgrade thrombocytopenia in GSTP 1 AA genotype patients were(8.91 ± 1.25),(9.02 ± 1.19),(11.56 ± 1.58)d after chemotherapy;those of patients with GSTP 1 313 allele G(AG/GG genotype) were(8.61 ± 1.17),(8.68 ± 1.19),(11.44 ± 1.34)d after chemotherapy. The implantation time of leukocyte,neutrophils and platelet in patients with GSTP 1 AA genotype were(11.98±1.99),(10.44±1.35),(15.55±2.18)d after autologus peripheral blood stem cell reinfusion;those of patients with GSTP1 313 allele G(AG/GG genotype)were(12.41±2.44),(10.36±1.62),(16.29±3.15)d after autologus peripheral blood stem cell reinfusion. The case number of grade Ⅲ-Ⅳ anemia were 24 and 11,accounting for 43.64% and 39.29% of corresponding genotype patients. The case number of agranulocytosis fever in patients with GSTP 1 AA genotype or GSTP 1 313 allele G(AG/GG genotype)were 21 and 11 during transplantation,accounting for 38.18% and 39.29% of corresponding genotype patients, respectively,without statistical significantly(P>0.05). CONCLUSIONS:There is no relationship between GSTP 1 gene polymorphism and hematological toxicity of AHSCT patients receiving CBV regimen.

Objective@#To investigate the clinical features, diagnosis, treatment and prognosis of primary intestinal lymphoma (PIL) .@*Methods@#The characteristics, diagnosis, treatment methods, and follow-up outcomes of 99 PIL patients, diagnosed in Peking university cancer hospital between Nov.1,1995 and Nov. 30, 2013.@*Results@#There were 65 males and 34 females with a median age of 50 years. The majority of clinical manifestation were non-specific gastrointestinal symptoms, 67.68% of cases presented abdominal pain, 26.26% with acute abdomen. The most common primary sites of ileum and ileocecus were identified in 21 cases, respectively. The positive rate of endoscopic was only 24.24%, and 69 cases were diagnosed by operation. 71 patients (71.72%) were stageⅠ-Ⅱand 28 patients (28.28%) were stage Ⅳ. Hodgkin’s lymphoma was not found in all patients. Of the 99 cases, 77 were B-cell origin (77.78%) and 22 were T-cell origin. 55 cases (55.56%) were diagnosed with diffuse large B cell lymphoma (DLBCL) . 60 cases presented IPI score 0-1 point. The median overall survival (OS) was 100.0 months, and 5 year overall survival (5y-OS) was 53.5%. By multiple-factors analysis, T-cell origin lymphoma was significantly correlated with poor prognosis (P<0.05) . There was no difference of the median OS between the patients with operation and chemotherapy alone (79.0 vs 123.0 months, P=0.616) .@*Conclusion@#PIL is commonly seen in males. Abdominal pain is the most common clinical manifestations and the most primary sites are ileum and ileocecus. The diagnosis value of the endoscopic is limited. DLBCL is the most common pathologic type of PIL. T-cell origin lymphoma is an independent prognostic factor for PIL. Surgery is still commonly used in the diagnosis and treatment of PIL, and the operation do not increase the risk of death of patients with PIL.

<p><b>OBJECTIVE</b>To analyze clinical features and outcomes of non-upper aerodigestive tract NK/T-cell lymphoma (NUAT-NKTCL).</p><p><b>METHODS</b>Clinical data of 44 patients with NUAT-NKTCL diagnosed at Peking University Cancer Hospital between 1999 and 2013 were retrospectively analyzed.</p><p><b>RESULTS</b>Of the 44 patients, there were 31 males and 13 females with a median age of 39 years (range, 15 to 82 years). 27 patients (61.4%) were stage III/IV, 28(63.6%) with B symptoms, 12(27.3%) ECOG ≥ 2, 18 (40.9%) IPI score ≥ 3, and 48.8% patients had elevated serum lactate dehydrogenase. The common primary sites were skin (21/44, 47.2%) and intestinal tract (11/44, 25.0%). All the 44 patients received systemic chemotherapy. After a median follow-up of 13.5 months (range, 0.3-121.0 months), 32 patients died, and the median overall survival (OS) was 16 months with 1-year OS rate as 54.1%. CR rate of the 26 patients received CHOP or CHOPE regimens as the first line chemotherapy was 19.2% (5/26). Then L-asparaginase (L-ASP)- based regimens were used for salvage treatment, with CR rate of 47.7% and the median OS of 13 months. CR rate of the other 18 patients received L-ASP-based regimens in the firstline therapy was 55.6% (10/18) with the median OS of 16 months.

Objective:To study the clinical features, therapeutic effects, survival time, and prognosis of patents with mantle cell lymphoma (MCL). Methods:Clinical data of 98 MCL patients admitted from January 2005 to December 2013 were retrospectively an-alyzed. Results:The median age was 61 years old, and the male-to-female ratio was 2.9∶1. Among these cases, 85 (86.8%) were in Ann Arbor stageⅢ-Ⅳ, 46 (46.9%) had bone marrow involvement, 25 (25.5%) had digestive tract involvement, and 53 chose R-CHOP as first-line treatment. The expected 3-year overall survival (OS) of these patients was only 61.4%. A total of 14 cases were treated with R-CHOP followed by ASCT. The expected 5-year OS was 92.3%, and the OS of the ASCT group was significantly higher than that of the R-CHOP group (75.5 months vs. 43.6 months, P=0.039). Elevated ESR,>60 years old, increased LDH level, B symptoms, and Ki-67≥25% were poor prognostic factors. Conclusion: Most patients with MCL were elder adults with bone marrow involvement. R-CHOP followed by ASCT had better clinical efficacy than conventional chemotherapy in the treatment of MCL.

Objective:To investigate the safety and efficacy of a modified baseline BEACOPP regimen(bleomycin+etoposide+adriamycin+cyclophosphamide+vincristine+ procarbazine hydrochloride+ prednisone) in the treatment of advanced Hodgkin 's lymphoma (HL). Methods:From March 2006 to September 2008, 22 previously untreated patients with stages Ⅱ(bulky), Ⅲ and Ⅳ HL were treated with a modified baseline BEACOPP regimen. Each patient was scheduled to receive 6 to 8 cycles of BEACOPP with consolidation radiotherapy to bulky (≥5 cm) or residual disease.Results:There were 11 males and 11 females with a median age of 28 years (15 to 61 years old). Twelve patients (54.5%) had nodular sclerosis HL, and 10(45.5%) had mixed cellularity HL. There were 4 patients in stageⅡ, 7 in stage Ⅲ and 11 in stage Ⅳ. Sixteen patients (72.7%) achieved a complete remission (CR) and 5 patients (22.7%) had partial remission (PR). The total effective rate (CR+PR) was 95.5%. Among all kinds of clinical factors International Prognostic Score (IPS) had significant effect on CR rate (P=0.011). The 1-, 2- and 3-year total survival rates were the same (95.5%); the 1-, 2- and 3-year progression-free survival (PFS) rates were 72.7%, 53.1% and 53.1%, respectively;the 1-, 2- and 3-year disease-free survival rates were 85.9%, 76.4% and 76.4%,respectively. Univariate analysis showed that the gender, IPS and whether achieving CR had significant effects on PFS (P<0.05). The main toxic effects were bone marrow depression and liver injury. Three patients (13.6%) had grade Ⅲ drug-induced lung injury. No treatment-related death was observed.Conclusion:The modified baseline BEACOPP regimen was effective and safe for treatment of newly diagnosed patients with advanced HL.

Objective To explore the feasibility of expansion for NK cells and the therapeutic efficacy improvement of rituximab by combinational Chemo-immunotherapy of rituximab and inter]eukin-2. To establish a clinical chemo-immunotherapy therapy regime of rituximab and interleukin-2(IL-2) for patients with diffuse large B-cell lymphoma (DLBCL). Methods The clinical data of 24 initially treated inpatients with DLBCL from Aug 2008 to Mar 2009 were analyzed by prospective non-randomized study. Patients in the treatment group (12 cases) were treated by IL-2 plus R-CHOP regime and those in the control group (12 cases)only by R-CHOP. The absolute quantity of NK cells before and after IL-2 and/or R-CHOP treatment in both groups were detected with FCM and compared, and the therapy efficacy and adverse reactions were evaluated.Results The complete remission (CR) rate was 60%(6/10) and the overall response (OR)rate was 80%(8/10)in the treatment group. The CR rate was 50%(5/10) and the OR rate was 70 %(7/10) in the control group.The proliferation of the NK cells in the treatment group was significantly effective compared with that in the control group (P=0.015). The descending range of NK cells between pre-and post-treatment in the treatment group was significantly lower than that in the control group(P =0.005). The quantity of NK cells after treatment by IL-2 was significantly increased than that before treatment by IL-2 in the treatment group (P=0.03). Among 10 patients in the treatment group, 3 cases have got diarrhea and 3 fever. Conclusion Treatment by IL-2 plus R-CHOP can increase the NK cell quantity in patients with DLBCL and may reduce lethal effect for NK cells by chemotherapy. The patients can tolerant the adverse reactions of IL-2 combined with R-CHOP therapy.

Objective To explore the abdominal pain as initial symptom of non-digestive diseases,the causes of misdiagnosis. Methods 74 patients with clear diagnosis non-digestive diseases which initial symptom was acute abdominal pain were analyzed. Results The most common causes of misdiagnosis were blood system diseases,circulatory diseases,metabolic diseases,endocrine system diseases,respiratory diseases,nervous system disease,accounting for 35.1% ,25.7% ,10. 8% ,8. 1% ,6. 8% ,6. 8%.The rest,such as the urinary system diseases,toxic diseases were not rare. Conclusion Non-digestive diseases which initial symptom was acute abdominal pain could be caused by the body's various systems,and the causes were complex,the diseases conditions were critical and changed rapidly,so it was difficult to diagnose and had to be Paid attention on.

Objective To investigate the prevalence of liver damage in B-cell lymphoma patients with positive HBV surface antigen(HBsAg)after rituximab and chemotherapy.Methods Records of 19 B-cell lymphoma patients with positive HBV surface antigen(HBsAg)after rituximab and chemotherapy from June,2001 to Aug,2007 in Beijing Cancer Hospital were reviewed to analyze the prevalence of liver damage.At the same time,the relationship between the level of HBV-DNA and the damage of liver was analysed.Results According to WHO criteria of liver toxicity,of the 19 patients,12(63.2%)suffered liver damage,4(21.1%)patients in grade Ⅰ,6(31.2%)patients in grade Ⅱ and 2(10.5%)patients in grade Ⅲ.None of the patients in this study experienced grade Ⅳ liver toxicity.Of the 6 patients with HBV-DNA>104 copy/ml before therapy,5(83.3%)suffered liver damage.Of the 5 patients with HBV-DNA<104 copy/ml before therapy,3(60%)suffered liver damage.Conclusion The prevalence of liver damage is higher in B-cell lymphoma patients with positive HBsAg after rituximab and chemotherapy.These patients should be closely monitored for liver function when they received rituximab therapy and should reveive anti-HBV therapy.
