OBJECTIVE: To assess changes of nutritional status by comprehensive nutrition assessment including nutritional risk screening, dietary assessment, blood biochemical index, and body composition in acute leukemia patients who had undergone chemotherapy. METHODS: A total of 169 patients with acute leukemia treated at The First Affiliated Hospital of Soochow University from June 2018 to August 2019 were recruited for this study. Before and after chemotherapy, the NRS-2002 and PG-SGA scales, dietary intake, blood biochemical index and body composition were evaluated to compare the changes of nutritional status. RESULTS: NRS-2002 score and PG-SGA score after chemotherapy were significantly increased than those before chemotherapy (P<0.001). Many patients had insufficient nutritional intake during chemotherapy, and the dietary intake score of patients with induction chemotherapy was significantly lower than that of patients with consolidation chemotherapy (P=0.043). The results of multivariate analysis showed that induction chemotherapy was the independent risk factor for the increase of PG-SGA scores and the decrease of dietary intake (all P<0.05). After chemotherapy, the white blood cell count, hemoglobin, and platelet count were significantly decreased (P<0.001), the prealbumin was significantly increased (P<0.001), and the blood glucose was increased (P=0.04), but albumin was not significantly changed. The weight, body mass index, fat-free mass, skeletal muscle mass and intracellular water were all significantly decreased (P<0.001), and visceral fat area was increased significantly after chemotherapy (P<0.05), especially in newly-diagnosed acute lymphoblastic leukemia patients after the induction of chemotherapy. CONCLUSION The nutritional status of patients with acute leukemia has undergone significant changes after chemotherapy. A single indicator has limited significance for nutritional status assessment. Comprehensive assessment of nutritional status by multiple tools is worthy of clinical application.

Objective: To investigate the efficacy and predictors of autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of T lymphoblastic lymphoma (T-LBL) . Methods: 41 patients with T-LBL who underwent auto-HSCT from April 2006 to July 2017 in the Department of Hematology, the First Affiliated Hospital of Soochow University and the Department of Lymphoma, Peking University Cancer Hospital were analyzed retrospectively. Results: ①Among 41 patients, there were 30 males and 11 females with median age of 24 (11-53) years old. According to the Ann Arbor staging, 33 (80.5%) patients were in stage Ⅲ/Ⅳ. 12 (29.3%) patients have mediastinal involvement, and 20 (48.8%) patients have bone marrow (BM) involvement. Before transplantation, there were 26 (63.4%) patients who achieved first complete remission (CR(1)) , the other 15 (36.6%) patients were in the non-CR(1) group, and there were 29 (70.7%) patients in the low-intermediate risk group (IPI<3 scores) , the other 12 (34.1%) patients were in the middle-high risk group (IPI≥3 scores) . ②The median follow-up was 29 (3-98) months. The 3-year overall survival (OS) and progression-free survival (PFS) for 41 patients were (64.3±8.2) % and (66.0±7.8) %, respectively. 3-year cumulative recurrence rate (CIR) was (30.7±7.4) %, and 3-year non-recurring mortality (NRM) was (4.8±4.6) %. ③The 3-year OS of the CR(1) group and the non-CR(1) group were (83.4±7.6) % and (38.9±12.9) % (P=0.010) , and the 3-year PFS of two groups were (83.8±7.4) % and (40.0±12.6) % (P=0.006) , respectively. The 3-year CIR of these two groups were (16.2±7.4) % and (53.3±12.9) % (P=0.015) , and the 3-year NRM were 0 and (14.3±13.2) % (P=0.157) , respectively. ④The 3-year OS of the IPI low-intermediate risk group and the high-intermediate risk group were (76.9±8.4) % and (35.7±15.2) % (P=0.014) and the 3-year PFS were (77.4±8.2) % and (40.0±14.6) (P=0.011) , respectively. The 3-year CIR of these two groups were (18.1±7.3) % and (60.0±14.6) % (P=0.006) , and the 3-year NRM were (5.6±5.4) % and 0 (P=0.683) , respectively. The OS and PFS of patients with low-intermediate risk group were significantly higher than the other group. Conclusion: Auto-HSCT could improve the survival of T-LBL. Pre-transplant status and IPI score are important predictors for survival T-LBL patients with auto-HSCT.

OBJECTIVETo observe changes of learning and memory ability (LMA) in burn rats with depression, and study the relationship between LMA and expression of hippocampal NMDA.

METHODSAccording to simple random method, 46 Wistar rats were divided into burn group (B, with 30% TBSA deep partial-thickness burn, n = 10), depression group (D, with moderate stress stimulation in chronic and unpredictable, n = 12), B + D group (with the same stress stimulation inflicted to B group after burn, n = 12), healthy control group ( HC, without treatment, n = 12). Changes in escape latency was examined in water maze test. Expression of hippocampal NMDA in CA1, CA2 regions and dentate gyrus were observed with immunohistochemistry.

RESULTSCompared with that of HC group (22 +/- 20 s), water maze escape latency in B, D, B + D groups on 2 day after training prolonged (38 +/- 31, 41 +/- 36, 42 +/- 33 s, respectively, P < 0.05 or P < 0.01). Water maze escape latency in B + D group on 4th day after training was longer than that of other groups (P < 0.01). There was no obvious difference in positive expression of NMDA in CA1, CA2 regions among groups (P > 0.05). The positive count of NMDA in dentate gyrus in D group (198 +/- 14) and B + D group (191 +/- 6) were lower than that of HC group (224 +/- 23, P < 0.05 or P < 0.01), but there was no obvious difference between HC group and B group (219 +/- 25, P > 0.05).

CONCLUSIONSBurn complicated with depression can reduce LMA, which may be due to a decrease in NMDA in dentate gyrus.

Quantitative structure-property relationships (QSPR) were developed to predict the pK(a) values of sulfa drugs via heuristic method (HM) and gene expression programming (GEP). The descriptors of 31 sulfa drugs were calculated by the software CODESSA, which can calculate constitutional, topological, geometrical, electrostatic, and quantum chemical descriptors. HM was also used for the preselection of 4 appropriate molecular descriptors. Linear and nonlinear QSPR models were developed based on the HM and GEP separately and two prediction models lead to a good correlation coefficient (R) of 0.90 and 0.95. The two QSPR models are tseful in predicting pK(a) during the discovery of new drugs and providing theory information for studying the new drugs.

In order to construct a single chain fragment variable (ScFv) phage display library against ovarian tumor, by using RT-PCR, the human heavy chain variable region genes (VH) and light chain variable region genes (VL) were amplified from lymphocytes of ovarian tumor patients and subsequently assembled into ScFv genes by SOE. The resulting ScFv genes were electrotransformed into E. coli TG1 and amplified with the co-infection of helper phage M13KO7 to obtain phage display library. The capacity and titer of the resulting library were detected. The phage antibody library with a capacity of approximately 3 x 10(9) cfu/microg was obtained. After amplification with helper phage, the titer of antibody library reached 5 x 10(12) cfu/mL. Human ScFv library against ovarian tumor was constructed successfully, which laid a foundation for the screening of ovarian tumor specific ScFv for the radioimmunoimaging diagnosis of ovarian tumor.

Objective To summarize the clinical experience in liver retransplantation. Methods From June 2002 to December 2005,a total of 185 cases of liver transplantation were performed in our hospital,including 8 cases of retransplantation.Those clinical data were analyzed retrospectively. Results The rate of liver retransplantation was 4.32%.The average MELD scores before primary transplantation and retransplantation were 15.6 and 23.9,respectively.The average interval between primary transplantation and retransplantation was 316 days(78~725 days).Causes of retransplantation included 3 cases of biliary complications,2 cases of chronic rejection,1 case of hepatic artery thrombosis,1 case of acute rejection and 1 case of recurrence of hepatitis B.The former 3 cases died of severe infection combined with multiple organ failure 101,16 and 28 days after retransplantation.The latter 5 cases recovered smoothly,and have survived 27,12,8,4 and 3 months up to now. Conclusion Liver retransplantation is an effective way to save the patient with hepatic allograft failure.Good knowledge of the indications of retransplantation,careful selection of the operation time,excellent surgical skills and meticulous postoperative management will contribute to the success of liver retransplantation.
