Traditional Chinese medicine (TCM) serves as a treasure trove of ancient knowledge, holding a crucial position in the medical field. However, the exploration of TCM's extensive information has been hindered by challenges related to data standardization, completeness, and accuracy, primarily due to the decentralized distribution of TCM resources. To address these issues, we developed a platform for TCM knowledge discovery (TCMKD, https://cbcb.cdutcm.edu.cn/TCMKD/). Seven types of data, including syndromes, formulas, Chinese patent drugs (CPDs), Chinese medicinal materials (CMMs), ingredients, targets, and diseases, were manually proofread and consolidated within TCMKD. To strengthen the integration of TCM with modern medicine, TCMKD employs analytical methods such as TCM data mining, enrichment analysis, and network localization and separation. These tools help elucidate the molecular-level commonalities between TCM and contemporary scientific insights. In addition to its analytical capabilities, a quick question and answer (Q&A) system is also embedded within TCMKD to query the database efficiently, thereby improving the interactivity of the platform. The platform also provides a TCM text annotation tool, offering a simple and efficient method for TCM text mining. Overall, TCMKD not only has the potential to become a pivotal repository for TCM, delving into the pharmacological foundations of TCM treatments, but its flexible embedded tools and algorithms can also be applied to the study of other traditional medical systems, extending beyond just TCM.

Objective:To analyze the efficacy of allo-HSCT with total body irradiation (TBI) and chemotherapy alone in the treatment of adult ALL and to explore the factors affecting prognosis.Methods:The clinical data of 95 adult patients with ALL who underwent allo-HSCT from January 2015 to August 2022 were included. According to the conditioning regimen, the patients were divided into two groups: the TBI plus cyclophosphamide (TBI/Cy) group ( n=53) and the busulfan plus cyclophosphamide (Bu/Cy) group ( n=42). Hematopoietic reconstitution after transplantation, GVHD, transplantation-related complications, relapse rate (RR), non-relapse mortality (NRM), OS, and LFS were compared, and the factors related to prognosis were analyzed. Results:The median time of neutrophil engraftment was 14 (10-25) days in the TBI/Cy group and 14 (10-24) days in the Bu/Cy group ( P=0.106). The median time of megakaryocyte engraftment was 17 (10-42) days in the TBI/Cy group and 19 (11-42) days in the Bu/Cy group ( P=0.488). The incidence of grade Ⅱ-Ⅳ acute GVHD (aGVHD) in the TBI/Cy and Bu/Cy groups was 41.5% and 35.7%, respectively ( P=0.565). The incidence of grade Ⅲ-Ⅳ aGVHD in these two groups was 24.5% and 4.8%, respectively ( P=0.009). The incidence of severe chronic GVHD in the two groups was 16.7% and 13.5%, respectively ( P=0.689). The incidence of cytomegalovirus infection, Epstein-Barr virus infection, severe infection, and hemorrhagic cystitis in the two groups was 41.5% and 35.7% ( P=0.565), 34.0% and 35.7% ( P=0.859), 43.4% and 33.3% ( P=0.318), and 20.8% and 50.0% ( P=0.003), respectively. The median follow-up time was 37.1 months and 53.3 months in the TBI/Cy and Bu/Cy groups, respectively. The 2-year cumulative RR was 17.0% in the TBI/Cy group and 42.9% in the Bu/Cy group ( P=0.017). The 2-year cumulative NRM was 24.5% and 7.1%, respectively ( P=0.120). The 2-year LFS was 58.5% and 50.0%, respectively ( P=0.466). The 2-year OS rate was 69.8% and 64.3%, respectively ( P=0.697). In the multivariate analysis, the conditioning regimen containing TBI was a protective factor for relapse after transplantation ( HR=0.304, 95% CI 0.135-0.688, P=0.004), whereas the effect on NRM was not significant ( HR=1.393, 95% CI 0.355-5.462, P=0.634). Infection was an independent risk factor for OS after allo-HSCT in adult patients with ALL. Conclusion:allo-HSCT based on TBI conditioning regimen had lower relapse rate and lower incidence of hemorrhagic cystitis for adult ALL, compared with chemotherapy regimen. While the incidence o grade Ⅲ/Ⅳ aGVHD was hgher in TBI conditioning regimen than that in chemotherapy regimen.

Case 1: A 27-year-old female with ALK-positive anaplastic large cell lymphoma/leukemia; Case 2: A 27-year-old male with acute myeloid leukemia; Case 3: A 56-year-old male with myelodysplastic syndrome. These three patients underwent haploid hematopoietic stem cell transplantation and experienced severe oral mucosal inflammation, nausea, vomiting, diarrhea, and other symptoms over a long period, which significantly restricted eating. Neurological and psychiatric symptoms appeared at 50, 38, and 50 days following transplantation, respectively. The diagnosis of Wernicke encephalopathy was made by head magnetic resonance imaging, whereas the condition improved significantly after intravenous infusion of vitamin B 1.

Objective:To explore the clinical efficacy and risk factors of umbilical cord mesenchymal stem cells (UCMSCs) infusion at an early stage (i.e.gross hematuria) for hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The relevant clinical data were retrospectively reviewed for 300 patients undergoing allo-HSCT from January 2016 to July 2021.According to the presence or absence of HC, they were assigned into two groups of HC (n=89) and non-HC (control, n=211). According to whether or not receiving an infusion of UCMSCs, 51 patients of HC degree Ⅱ-Ⅳ were divided into two groups of UCMSC infusion and non-infusion.The risk factors of HC after allo-HSCT were analyzed by χ2 test.Logistic regression was employed for multivariate analysis of P<0.05.Mann-Whitney U test was utilized for statistically analyzing the duration of gross hematuria and urinary tract irritation symptoms and evaluating the clinical efficacy of UCMSCs infusion for HC. Results:Among them, 89 (29.67%) developed HC post-allo-HSCT.Clinical grades were Ⅰ (n=38, 42.70%), Ⅱ (n=36, 40.45%), Ⅲ (n=13, 14.61%) and Ⅳ (n=2, 2.25%). The median occurrence time was 29 (21.5-35.0) days post-allo-HSCT.In univariate analysis, age ≤30 years, haploid transplantation, antithymocyte globulin (ATG), acute graft-versus-host disease (aGVHD), CMV-DNA positive pretreatment significantly boosted the risk of HC ( P<0.05). In multivariate analysis, aGVHD was an independent risk factor for HC ( OR=10.281, 95% CI: 1.606-65.813, P=0.014). Among 89 HC patients, 38 grade Ⅰ patients were complete remission(CR). Among 51 patients of grade Ⅱ-Ⅳ HC, the outcomes were CR (n=48) and non-remission(NR)(n=3). And 24/51 of them received UCMSCs plus conventional treatment.The duration of gross hematuria was shorter in UCMSCs infusion group than that in UCMSCs non-infusion group [12(9-17) vs 17(12.0-26.5) day] and the difference was statistically significant ( P=0.045). And the duration of urinary tract irritation symptoms was shorter in UCMSCs infusion group than that in UCMSCs non-infusion group [18(11-30) vs 27(18.0-35.5) days] and the difference was statistically significant ( P=0.048). Conclusions:Indicated for post-ALLO-HSCT HC, infusion of UCMSCs may significantly shorten the course of disease.Age ≤30 years, haploid transplantation and preconditioning with positive ATG, aGVHD and CMV-DNA may boost the risks of HC post-allo-HSCT.And aGVHD is an independent risk factor for HC after allo-HSCT.

Objective:To evaluate the safety and efficacy of bortezomib plus highdose melphalan (L-phenylalanine nitrogen mustard) (Bor-HDM) pretreatment regimen for multiple myeloma (MM) with autologous hematopoietic stem cell transplantation (ASCT).Methods:From August 2008 to December 2021, the relevant clinical data were retrospectively reviewed for 58 MM patients undergoing MM transplantation.The conditioning regimens were Bor-HDM (n=36) and HDM (n=22). Non-hematopoietic adverse reactions, hematopoietic reconstruction time, remission rate post-ASCT and minimal negative rate of residual disease (MRD) on flow cytometry within 3 months post-ASCT and survivals were analyzed.Results:In Bor-HDM and HDM groups, median time of neutrophil engraftment was 12(8-30) and 11(8-29) day and median time of platelet reconstitution 16(8-33) and 16(7-32) day respectively.There was no significant inter-group difference ( P=0.890, P=0.638). In Bor-HDM group, the most common non-hematological adverse reactions were nausea (n=21, 58.0%) and diarrhea (n=11, 30.6%). There was no transplant-related death.Complete remission (CR) rate was (25/36, 69.4%) versus (9/22, 40.9%). The inter-group difference was statistically significant ( P=0.032). Median follow-up period was 29.0(2.0-91.0) vs. 20.5(5.0-114.0) month, 3-year progression-free survival(PFS)62.1% vs. 39.7% and 3-year overall survival(OS) 83.8% vs. 62.5%.There were relapse (n=10 vs.10) and death (n=6 vs. 7). Median PFS in Bor-HDM and HDM groups was non-attained and 27 months( P=0.047) and median OS time non-attained and 40 months respectively ( P=0.282). Multivariate analysis revealed that CR was an independent risk factor for PFS ( HR=28.896, 95% CI: 6.130-136.198, P<0.001). Non-CR was an independent risk factor for OS ( HR=3.843, 95% CI: 1.334-11.071, P=0.013; HR=28.595, 95% CI: 6.273-130.355, P<0.001). Conclusions:Bor-HDM pretreatment regimen of ASCT is both safe and efficacious for MM patients.

Objective To investigate the effects of chronic restraint stress on learning and memory in Wistar and Sprague-Dawley (SD) rats.Methods Healthy adult male Wistar rats (n=6) and Sprague-Dawley rats (n=6) were subjected to restraint stress 10 h daily for 28 days.After that, all rats were tested for recognition memory by novel object recognition test , and spatial memory and working memory by Morris water maze test .Results After restraint for 10 h daily for 28 days, the restraint rats of the two strains demonstrated lower discrimination index (DI)than the control group, but on-ly SD rats showed significant difference ( P<0.05 ) .The restraint SD rats showed higher escape latency than the control rats, and on the 5th day the difference became significant (P<0.05), and there was no significant difference between Wistar restraint and control rats .The working memory test showed that restraint SD rats exibited longer escape latency than the control rats (P<0.05), while Wistar rats didn’t show significant difference between the two groups .Conclusions The results of this study demonstrate that the impairments of learning and memory in SD rats subjected to restraint 10 hour per day for 28 days are more serious than that in the Wistar rats .Therefore , SD rats may be a better choice as an animal model to study the effects of chronic restraint stress on learning and memory impairment .

BACKGROUND:The comfortable shoes can absorb or reduce the impact force from the ground. Is the damped system is absent in shoes to relieve the impulse,the feet will be extremely tired,even damage the human knee joint,waist,back and brain. OBJECTIVE:To measure the changes of human plantar pressure by different sole hardness through the measurement system of plantar pressure. DESIGN,TIME AND SETTING:An observation experiment was performed in the Shanghai University of Sport between December 2008 and February 2009.PARTICIPANTS:Six volunteers wearing the experimental designed shoes were recruited from Nanjing Institute of Physical Education.METHODS:Three pairs of experimental shoes weighing 103 g were measured with shore hardness tester,as 51,62 and 69 hardness values. Accordingly they were named soft shoes,medium hardness shoes and hard shoes. The subjects were asked to do a 60-minute walk test at the speed of 2 m/s on the running platform with the experimental designed shoes,and they were determined using the insole plantar pressure measurement system of German's Novel style series of Emed-pedar.MAIN OUTCOME MEASURE:The pressure,contact area and impulse in the sole of foot.RESULTS:With the increase in hardness soles,the pressure of center plantar was shown to move from the medial first metatarsal outwards by turns. Compared with barefoot walking,the trail length of the center plantar was prolonged in subjects with medium hardness shoes and hard shoes,while shortened in subjects with soft shoes. The total pressure when you walked with soft shoes and medium hardness shoes were reduced than barefoot walking,and the pressure of walking phase wearing these two types of shoes were also reduced,while total pressure and walking phase pressure with hard shoes were both increased compared with barefoot walking. The contact area was similar between soft shoes and medium hardness shoes,but the smallest in the hard shoes. Except the increase in the initial 10 minutes,the soft shoes had no change with the medium hardness shoes. The hard shoes were firstly increased but then declined. The total impulse of medium hardness shoes was the closest to bare feet,while that of soft shoes and hard shoes were increased compared with bare foot.CONCLUSION:The plantar pressure was the greatest in the hard shoes,then medium hardness shoes and last soft shoes;the contact area was the greatest in soft shoes,then medium hardness shoes and last hard shoes;the impulse was the greatest in hard shoes,then soft shoes,and last medium hardness shoes.

Objective To assess the feasibility and outcomes of fractionated stereotactice radiation therapy(FSRT) for brain metastases more than 3 cm in diameter. Methods From September 1996 to July 2006,47 patients(34 male and 13 female)with brain metastases larger than 3 cm were treated with FSRT. The median age was 58(range,31-87) years old. Pathologic diagnosis was adenocarcinoma in 19 patients, squamacarcinoma in 7, small cell carcinoma in 7, adeno-squamacarcinoma in 3, melanoma in 2, poor differen-tiated carcinoma, clear cell carcinoma, transitional cell carcinoma each in 1, and unknown in 6. FSRT was delivered as initial treatment for 26 patients, and as salvage therapy for 21. The largest diameter of brain me-tastases was 3.1-6.0 cm(median, 3.8 cm). Planning target volume were 2.5-33.8 cm3(median, 9.4 cm3). The median dose of FSRT was 30(range,16-57)Gy in 5(range,2 - 11) fractions. The treatment for primary tumor was surgery in 23 patients, radiotherapy and/or chemotherapy in 22, and none in 2. Results The last follow up was in April 2008. All patients were followed up and 33 had follow up more than 5 years. The 1-,2- and 5-year local control rate was 49%, 44% and 44%, respectively. The median survival time was 11 months(range,0.5-88.0 months, 95% CI=8.1-13.8 months). The corresponding overall survival rate was 40%, 17% and 6%, respectively. There were 46 patients died by the last follow up,including 21 died from brain metastases, 17 died from extracranial progression, and 8 died from other causes. Conclusion FSRT is safe and beneficial for selected patients with brain metastases larger than 3 cm.
