OBJECTIVE: To explore the effects of prognostic nutritional index (PNI) combined with D-dimer on the prognosis of patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). METHODS: The clinical data of 73 DLBCL patients at initial diagnosis were retrospectively evaluated, and the optimal cut-off point of PNI and D-dimer were determined by ROC curve. The overall survival (OS) rate and progression-free survival (PFS) rate in different subgroups were compared using Kaplan-Meier survival curves. Univariate and multivariate Cox regression analysis was performed to identify the factors associated with OS. RESULTS: Compared with the low PNI group (PNI<44.775), the high PNI group (PNI≥44.775) had better OS (P =0.022) and PFS (P =0.029), the 2-year OS rates of the two groups were 55.6% and 78.3% respectively (P =0.041). Compared with the high D-dimer group (D-dimer≥0.835), the low D-dimer group (D-dimer<0.835) had better OS (P <0.001) and PFS (P <0.001), the 2-year OS rates of the two groups were 51.4% and 86.8% respectively (P =0.001). Meanwhile, patients in the high PNI+ low D-dimer group had better OS (P =0.003) and PFS (P <0.001) than the other three groups, the 2-year OS rate was statistically different from the other three groups (P <0.05). The multivariate analysis revealed that NCCN-IPI (HR =2.083, 95%CI : 1.034-4.196, P =0.040), PNI (HR =0.267, 95%CI : 0.076-0.940, P =0.040) and PNI+D-dimer (HR =9.082, 95%CI : 1.329-62.079, P =0.024) were the independent risk factors affecting OS in patients with DLBCL. Subgroup analysis showed that PNI, D-dimer, and PNI combined with D-dimer could improve the prognostic stratification in low and low-intermediate risk DLBCL patients. CONCLUSION High PNI, low D-dimer and combination of high PNI and low D-dimer at initial diagnosis suggest a better prognosis in DLBCL patients.

OBJECTIVE: To preliminarily explore the applicable scenarios of an intraoral camera to assist oral anatomical landmarks recognition, so as to improve the clinical diagnosis and treatment mode, cultivate the concept of caring for patients, strengthen doctor-patient communication, assist experts to teach, and improve the clinical diagnosis and efficacy rate. METHODS: A new type of an intraoral camera was applied in the recognition of oral anatomy landmarks and four application scenarios were developed, namely: (1) clinical diagnosis and treatment scenarios, in which doctors used intraoral camera to conduct a comprehensive examination of patients in the mouth and take videos and photos; (2) doctor-patient communication scenarios, when the doctor told the patient about the treatment plan, the video or photo taken by the intraoral camera was displayed to the patient; (3) expert teaching scenarios, when the expert used an intraoral camera to teach in the patient's mouth, and the young doctor learned oral anatomical signs on the projection screen, with the study of theoretical lessons; (4) difficult case recording scenarios, in the process of clinical diagnosis and treatment, when encountering difficult cases, you could use intraoral camera to record and take photos for young doctors to discuss, and experts to comment and guide. RESULTS: The application of intraoral camera could: (1) improve the clinical diagnosis and treatment mode and raise the clinical diagnosis and efficacy rate; (2) stimulate young doctors' interest in learning, use intraoral camera in assessments, and skillfully combine theoretical knowledge of anatomical landmarks with clinical practice, so as to improve the teaching effect; (3) cultivate, through self or mutual use, the concept of caring for patients and reinforce the importance of gentle operation; (4) strengthen doctor-patient communication. Doctors could communicate with patients more visually, so that the patients could better understand their own situation, and strengthen the patients' trust in the doctors. CONCLUSION Intraoral camera can assist oral clinical diagnosis and treatment, such as the recognition of oral anatomical landmarks. It plays a certain role in promoting the improvement of clinical diagnosis and treatment mode, stimulating learning interest, cultivating the concept of caring for patients, and enhancing doctor-patient communication.

OBJECTIVE: To investigate the significance of a new risk stratification model (R2-ISS) in evaluating the prognosis of newly diagnosed multiple myeloma (MM). METHODS: Clinical data of 116 newly diagnosed MM patients admitted to Lanzhou University Second Hospital from June 2012 to March 2021 were retrospectively analyzed. According to R2-ISS, these patients were divided into four groups: low risk, low-intermediate risk, intermediate-high risk, and high risk. The significance of R2-ISS on prognosis of the patients was analyzed. RESULTS: Survival analysis showed that R2-ISS was associated with progression-free survival (PFS) (P=0.042) and overall survival (OS) (P=0.014). Cox univariate analysis showed that lactate dehydrogenase, serum calcium, serum creatinine, β₂-microglobulin, ISS, R-ISS, R2-ISS, t(4;14), and autologous hematopoietic stem cell transplantation (ASCT) were the influencing factors of OS in newly diagnosed MM patients (all P<0.05). Cox multivariate analysis showed that R-ISS, R2-ISS, and ASCT were independent risk factors affecting OS (all P<0.05). In addition, survival analysis of patients with different R2-ISS showed that ASCT improved PFS and OS. CONCLUSION R2-ISS has prognostic value for newly diagnosed MM patients, while ASCT can improve the prognosis of patients with different R2-ISS.

OBJECTIVE: To investigate the toxicity management and efficacy evaluation of BCMA-chimeric antigen receptor T cells(CART) in the treatment of relapsed and refractory multiple myeloma (MM). METHODS: The efficacy and adverse reactions of 21 patients with MM who received BCMA-CART treatment at the First Affiliated Hospital of Wenzhou Medical University from December 2017 to September 2020 were evaluated, and the efficacy assessment and survival analysis for high-risk patients and non-high-risk patients were evaluated. RESULTS: After infusion of BCMA-CART cells in 21 MM patients, the number of effective cases was 17, of which the complete remission (sCR/CR) was 10, and the partial remission (VGPR/PR) was 7. The median OS time for all patients was 19.4 months, and the median PFS time was 7.9 months. The number of patients with extramedullary disease(EMD), high-risk genetics, and ISS stage Ⅲ were 5, 15 and 8, and the effective number was 3, 11 and 6, respectively. The treatment of 3 patients without high-risk factors was effective. The median OS and median PFS of patients with EMD were 14.2 and 2.5 months, respectively, which were shorter than those of patients without EMD (19.4 months and 8.9 months, respectively). The median OS and median PFS of patients with high-risk cytogenetic factors and ISS Ⅲ were not significantly different from those of non-high-risk patients. Cytokine release syndrane (CRS) occurred in 20 patients, of which 14 cases were Grade 1 CRS, while 6 were Grade 2, no CRS of Grade 3 or above occurred. IL-6 receptor inhibitors were used in 9 patients. All CRS were controlled effectively, and no patients had neurological toxicity. CONCLUSION BCMA-CART is a certain curative effect in the treatment of relapsed and refractory multiple myeloma, and the adverse reactions can be well controlled through close monitoring and timely treatment.

OBJECTIVE: To evaluate the safety and efficacy of BUCY (busulfan and cyclophosphamide) conditioning regimen for autologous hematopoietic stem cell transplantation (ASCT) in patients with multiple myeloma (MM). METHODS: The clinical data of 72 MM patients received transplantation in the Hematology Department of the First Affiliated Hospital of Soochow University from May 2012 to June 2015 were retrospectively analyzed. Among them, 36 patients received BUCY conditioning regimen while the others received high-dose melphalan (HDM) conditioning regimen. The complication, post-transplantation hematopoietic reconstitution and efficacy between the two groups were compared. RESULTS: There were no significant differences in sex, age, isotype, stage, induction therapy, mobilization method and proportion of conditioning regimen with Bortezomib between the two groups. The median time of neutrophil engraftment for the patients in BUCY and HDM groups was 10 (8-17) and 10 (9-13) d (P=0.046), and the median time of platelet engraftment was 10 (8-18) and 11 (9-47) d (P=0.017), respectively. The transplant related mortality of the patients in both groups was 2.7%. The CR rates of the patients after ASCT (38.9% and 50.0%) were higher than those before ASCT (27.8% and 19.4%) in the two groups. For the patients in BUCY group, the median follow-up time was 45 (0-61) months. Fifteen patients (41.7%) achieved disease progression. While for the patients in HDM group, the median follow-up time was 52(0-75) months. Twenty-two patients (61.1%) achieved disease progression. CONCLUSION The BUCY conditioning regimen is a safe and effective therapy for ASCT in patients with MM. Besides, in terms of safety and efficacy, BUCY regimen is not inferior to HDM regimen. BUCY regimen may replace HDM regimen as a standard conditioning regimen for ASCT in MM.

OBJECTIVE: To explore the influence of controlling nutritional status (CONUT) score on the prognosis of newly diagnosed patients with multiple myeloma (MM). METHODS: The clinical data 119 patients with MM who were diagnosed according to the international myeloma diagnostic criteria in Lanzhou University Second Hospital from April 2010 to October 2018 were collected and retrospectively analyzed. The relationship between clinical indexes, including age, sex, MM type, absolute lymphocyte count (ALC), absolute neutrophil count (ANC), absolute monocyte count (AMC), hemoglobin (Hb), platelet (PLT), β RESULTS: Compared with high-scoring group, low-scoring group had a better OS ［median OS was 43.3 months and 127.67 months, respectively, 95% confidence interval (CI): 57.065-78.345, P=0.038］. At the same time, the low-scoring group also had higher level of ALC, ANC, AMC, Hb, PLT, ALB, and CHO but lower of GLO. Multivariate survival analysis showed that age (HR=1.027, 95%CI: 1.000-1.054, P=0.048), AMC (HR=11.284, 95%CI: 22.968-42.897, P<0.001), CONUT score (HR=1.198, 95%CI: 1.036-1.385, P=0.015), M protein (non-IgG/IgG type) type (HR=0.503, 95%CI: 0.259-0.977, P=0.043) were independent factors affecting the prognosis of MM patients. CONCLUSION The CONUT score as an immune-nutrition score is a convenient and easy-to-obtain index to effectively predict the prognosis of MM patients.

OBJECTIVE: To detect the relationship between CTGF in the bone marrow of MM patients and osteolytic lesion of myeloma, moreover, to investigate the clinical significance of CTGF in MM. METHODS: Fifity-four MM patients treated in our hospital from March 2019 to April 2020 were enrolled, and 28 healthy volunteers were selected as the control group. The plasma in bone marrow of the patients was collected, and the ELISA was used to detect the level of CTGF in bone marrow plasma and the relationship between its and clinical characteristics were statistically analyzed. RESULTS: The CTGF level of MM patients was significantly higher than those in the healthy control group (P<0.001); the CTGF level in male patients was higher than that in female patients (P=0.007); the CTGF level in MM patients with osteolytic lesions was significantly higher than patients without osteolytic lesions and controls (P=0.007, P=0.001). The CTGF level in MM patients was positively correlated with the number of bone lesions (P<0.001, r=0.52). CTGF levels in patients with ≥3 bone lesions were significantly higher than those with <3 bone lesions and without bone lesions (P=0.014, P=0.002). ROC curve result showed that CTGF expression level shows a significant diagnostic value for MM bone disease (P<0.001). CONCLUSION The abnormally high expression of CTGF level in MM patients is related to the degree of myelomas osteolytic lesions and can reflect the progress of MM.

Purpose: We aimed to develop and validate individual prognostic models in a large cohort of cervical cancer patients that were primarily treated with radical hysterectomy. Materials and Methods: We analyzed 1,441 patients with early-stage cervical cancer treated between 2000 and 2008 from the Korean Gynecologic Oncology Group multi-institutional cohort: a train cohort (n=788) and a test cohort (n=653). Models predicting the risk for overall survival (OS), disease- free survival (DFS), lymphatic recurrence and hematogenous recurrence were developed using Cox analysis and stepwise backward selection and best-model options. The prognostic performance of each model was assessed in an independent patient cohort. Model-classified risk groups were compared to groups based on traditional risk factors. Results: Independent risk factors for OS, DFS, lymphatic recurrence, and hematogenous recurrence were identified for prediction model development. Different combinations of risk factors were shown for each outcome with best predictive value. In train cohort, area under the curve (AUC) at 2 and 5 years were 0.842/0.836 for recurrence, and 0.939/0.882 for OS. When applied to a test cohort, the model also showed accurate prediction result (AUC at 2 and 5 years were 0.799/0.723 for recurrence, and 0.844/0.806 for OS, respectively). The Kaplan-Meier plot by proposed model-classified risk groups showed more distinctive survival differences between each risk group. Conclusion We developed prognostic models for OS, DFS, lymphatic and hematogenous recurrence in patients with early-stage cervical cancer. Combining weighted clinicopathologic factors, the proposed model can give more individualized predictions in clinical practice.

OBJECTIVETo investigate the characteristics of collateral circulation in adult moyamoya disease (MMD).

METHODSThe clinical data were collected from all adult patients with MMD undergoing digital subtractive angiography (DSA) in our department from 2006 to 2016. Based on the imaging findings, the patients were divided into ischemia group and bleeding group. A double-blind analysis was conducted of the CT or magnetic resonance imaging findings and the severity of the disease was graded using the modified Suzuki score (mSS). We classified the anastomotic networks in MMD into the superficial meningeal type and deep parenchymal type. The superficial meningeal type was further classified into the leptomeningeal and the durocortical networks, and the deep parenchymal networks into subependymal networks and the inner striatal and inner thalamic networks.

RESULTSNo significant difference was found in the distribution of mSS scores between the hemorrhage group and the ischemic group (Χ=5.812, v=5, P=0.325), but the posterior communicating artery and internal carotid artery diameter ratio (Pcom/ICA ratio) was significantly greater in the hemorrhage group (t=2.119, v=108, P=0.036). The Pcom/ICA ratio differed significantly among the groups with different mSS scores (f=8.924, P=0.00), higher in groups with mSS scores of 3, 4 and 5. The incidence of anterior choroidal artery dilation differed significantly between hemorrhage and ischemic groups (Χ=11.79, P=0.001). The incidences of durocortical networks (Χ=0.327, P=0.567) and subependymal networks (Χ=0.011, P=0.917) were comparable between hemorrhage group and ischemic groups, but the incidence of leptomeningeal networks (P=0.018) and inner striatal and inner thalamic networks (Χ=7.551, P=0.006) differed significantly between the two groups.

CONCLUSIONThe collateral circulation vascular system is an important component of cerebral blood flow in MMD patients and varies from patient to patient. Patients with MMD exhibit increased Pcom/ICA ratio with abnormal expansion of the anterior choroidal artery, and the leptomeningeal networks and the inner striatal and inner thalamic networks are independent risk factors for cerebral hemorrhage.
