ObjectiveTo investigate the effects of Chaihu and Longgu Mulitang （CLMT） on hippocampal neural damage in the mouse model of depression via the extracellular signal-regulated protein kinase （ERK）/cAMP-response element-binding protein （CREB） signaling pathway. MethodsSeventy-eight male C57BL/6 mice were randomly allocated into normal control， model， low/medium/high-dose （2.89， 5.78， and 11.56 g·kg^-1， respectively） CLMT， and paroxetine （10 mg·kg^-1） groups. A depression model was established by chronic unpredictable mild stress （CUMS） combined with social isolation. Behavioral tests were carried out to evaluate depressive-like behaviors. Hematoxylin-eosin staining and Nissl staining were performed to assess hippocampal morphology and neuronal damage. Immunofluorescence was employed to detect glial fibrillary acidic protein （GFAP） and ionized calcium-binding adapter molecule 1 （Iba1）. Real-time PCR was employed to measure the mRNA levels of ERK and CREB. Western blot was employed to determine the expression of ERK/CREB pathway proteins and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. Molecular Operating Environment （MOE） software was used for molecular docking to evaluate the interactions between CLMT components and target proteins. ResultsCompared with the normal control group， the model group showed decreased sucrose preference （P0.01）， increased tail-suspension immobility time （P0.01）， decreased activity in the central region of the open field test （P0.01）， and decreased activity in the middle and open-arm region of the elevated plus maze test （P0.01）. The hippocampal area in the model group showed wrinkled cells and a reduction in the number of cells， neurons with reduced sizes and Nissl bodies， enhanced fluorescence intensity of GFAP and Iba1 （P0.01）， and down-regulated expression of phosphorylated （p）-ERK， p-CREB， and BDNF （P0.05， P0.01） and mRNA levels of ERK and CREB （P0.01）. Compared with the model group， the CLMT group showed increased body weight （P0.05， P0.01）， restored cell morphology， with only a small number of ruptured cells， normal neuronal structure and morphology with obvious nuclei and abundant Nissl bodies， weakened fluorescence intensity of GFAP and Iba1 （P0.05， P0.01）， up-regulated mRNA levels of ERK and CREB （P0.05， P0.01） and protein levels of phosphorylated （p）-ERK， p-CREB， and BDNF in the hippocampal tissue （P0.05， P0.01）. The results of molecular docking indicated that nine active ingredients in CLMT had good binding affinity with ERK and CREB. ConclusionCLMT may ameliorate the hippocampal nerve injury in the mouse model of depression by regulating the ERK/CREB pathway.

In order to clarify the effects of drought stress training on the quality and drought resistance of Codonopsis pilosula, this study used PEG to simulate drought stress and employed potting with water control for the drought stress training of C. pilosula plants. The polysaccharide content, secondary metabolites, antioxidant system, and photosynthetic pigment system of C. pilosula after drought stress training were analyzed. The results showed that the content of fructans in the root of C. pilosula increased after two rounds of drought stress treatment, and it was significantly higher than that of the control group. The accumulation of fructans in the root of C. pilosula showed an upward trend during the rehydration treatment. The content of lobetyolin and tangshenoside Ⅰ increased after drought stress treatment compared with that of the control group. The rehydration treatment caused first increasing and then decreasing in the content of lobetyolin, while it had no significant effect on the tangshenoside Ⅰcontent. The content of photosynthetic pigments decreased after drought stress treatment, and it gradually increased during the first round of rehydration and the second round of rehydration. Moreover, the increase was faster in the second round of rehydration than in the first round of rehydration. The content of the peroxidation product malondialdehyde(MDA) and the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) increased after drought stress treatment compared with those of the control group, and they showed a tendency of decreasing during rehydration. Moreover, the decrease was faster in the second round of rehydration than in the first round of rehydration. When the plants of C. pilosula after drought stress training were again subjected to severe drought stress, the wilting rate decreased significantly, and the biomass increases significantly. This study showed that the drought stress training could promote the accumulation of polysaccharides and secondary metabolites in the root of C. pilosula. When encountering drought stress again, C. pilosula plants could quickly regulate the antioxidant system and delay the decomposition of chlorophyll to respond to drought stress. The findings provide a theoretical basis for the ecological cultivation of C. pilosula in arid and semi-arid areas.

PURPOSE: Lateral patellar compression syndrome (LPCS) is characterized by a persistent abnormally high stress exerted on the lateral articular surface of the patella due to lateral patellar tilt without dislocation and lateral retinaculum contracture, leading to anterior knee pain. The purpose of this study is to evaluate the efficacy and prognosis of lateral retinaculum release (LRR) combined with chondroplasty in the treatment of LPCS. METHODS: This retrospective study evaluated 40 patients who underwent LRR combined with chondroplasty for LPCS between 2020 and 2021. The assessment included improvement in postoperative tenderness and knee joint function. Patients were evaluated using the Lysholm, Tegner, and International Knee Documentation Committee 2000 scoring systems, as well as the visual analog scale, both preoperatively and postoperatively, with the paired comparisons analyzed using a t-test. Additionally, intraoperative observations were made regarding knee joint lesions, including cartilage damage and osteophyte formation, with analysis by the Chi-square test. RESULTS: The visual analog scale score for tenderness showed a significant decrease after surgery (p < 0.001). Evaluation of knee joint function also indicated significant improvements, as demonstrated by increased Lysholm, Tegner, and International Knee Documentation Committee 2000 scores postoperatively (p < 0.001, p = 0.011, p < 0.001, respectively). Furthermore, all LPCS patients included in the study presented with cartilage injuries and osteophyte formation. Significant differences were noted in the incidence of cartilage damage and osteophyte formation at different locations within the knee among patients with LPCS. CONCLUSION LRR combined with chondroplasty is an effective surgical approach for treating patients with LPCS, with satisfactory recovery observed at the 1-year follow-up. Additionally, the incidence of cartilage damage and osteophyte formation in LPCS patients varies significantly depending on the specific location within the knee joint.

OBJECTIVE: To assess the efficacy and safety of a new conditioning regimen with chidamide and BEAM for autologous hematopoietic stem cell transplantation (AHSCT) in patients with lymphoma. METHODS: Medical records and further follow-up data from 85 patients with lymphoma from May 2015 to September 2020 in our hospital were retrospectively collected and analyzed. RESULTS: Among 85 patients, 52 cases accepted BEAM regimen and 33 cases accepted CBEAM followed by AHSCT. In CBEAM group, 18 patients (54.5%) received AHSCT as salvage therapy, while only 26.9% (14 cases) for salvage in BEAM group ( P < 0.01). CBEAM conditioning resulted in shorter neutrophil engraftment of 2 days, while no significant difference was found in platelet engraftment. Although the incidence of liver impairment was higher in CBEAM group (12.1%), the grade of impairment was only Ⅰ to Ⅱ. The two conditioning regimens both achieved good complete remission rate of over 90%, and no transplant-related death occurred. The median follow-up time in the CBEAM group was 18(12, 22) months, and 39(20, 59) months in the BEAM group. There were no significantly differences in 2-year progression-free survival (PFS) and overall survival (OS) rate between the two groups (P >0.05). In patients with refractory or relapsed non-Hodgkin lymphoma, the 2-year PFS rate after transplantation in BEAM group and CBEAM group was 74.1% and 92.9%, respectively (P >0.05), indicating that chidamide may have certain advantages in prolonging PFS. CONCLUSION CBEAM conditioning regimen has a good efficacy and safety in lymphoma patients before AHSCT, especially in refractory and relapsed non-Hodgkin lymphoma patients, suggesting that it could serve as an alternative conditioning regimen prior to AHSCT for lymphoma.

OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

OBJECTIVE: To investigate the characteristics of gut microbiota changes in patients with acute myeloid leukemia (AML) undergoing induction chemotherapy and to explore the relationship between infectious complications and gut microbiota. METHODS: Fecal samples were collected from 37 newly diagnosed AML patients at four time points: before induction chemotherapy, during chemotherapy, during the neutropenic phase, and during the recovery phase. Metagenomic sequencing was used to analyze the dynamic changes in gut microbiota. Correlation analyses were conducted to assess the relationship between changes in gut microbiota and the occurrence of infectious complications. RESULTS: During chemotherapy, the gut microbiota α-diversity (Shannon index) of AML patients exhibited significant fluctuations. Specifically, the diversity decreased significantly during induction chemotherapy, further declined during the neutropenic phase (P < 0.05, compared to baseline), and gradually recovered during the recovery phase, though not fully returning to baseline levels.The abundances of beneficial bacteria, such as Firmicutes and Bacteroidetes, gradually decreased during chemotherapy, whereas the abundances of opportunistic pathogens, including Enterococcus, Klebsiella, and Escherichia coli, progressively increased.Analysis of the dynamic changes in gut microbiota of seven patients with bloodstream infections revealed that the bloodstream infection pathogens could be detected in the gut microbiota of the corresponding patients, with their abundance gradually increasing during the course of infection. This finding suggests that bloodstream infections may be associated with opportunistic pathogens originating from the gut microbiota.Compared to non-infected patients, the baseline samples of infected patients showed a significantly lower relative abundance of Bacteroidetes (P < 0.05). Regression analysis indicated that Bacteroidetes abundance is an independent predictive factor for infectious complications (P < 0.05, OR =13.143). CONCLUSION During induction chemotherapy in AML patients, gut microbiota α-diversity fluctuates significantly, and the abundance of opportunistic pathogens increase, which may be associated with bloodstream infections. Patients with lower baseline Bacteroidetes abundance are more prone to infections, and its abundance can serve as an independent predictor of infectious complications.

Objective To explore the acupoint selection rules of acupuncture treatment for cerebellar ataxia using data mining techniques.Methods Taking the related literature of acupuncture treatment of cerebellar ataxia as the retrieval content,the computer retrieval of China National Knowledge Internet(CNKI),China Biomedical Literature Database(SinoMed),Wanfang Data Knowledge Service Platform(Wanfang),China Science and Technology Journal Database(VIP),American Biomedical Information Retrieval System(PubMed)and other major databases.The eligible acupoints in the literature were entered into the Microsoft Excel 2021 software table to establish a database of acupoints frequency,meridian tropism,specific acupoints,distribution sites and other information for acupuncture treatment of cerebellar ataxia.SPSS Modeler 18.0 Apriori algorithm,SPSS Statistics 25.0 and SPSS Modeler 18.0 Web complex network were used to analyze the association rules of the included prescription acupoints,Ward cluster analysis and draw the tree diagram and the Web network diagram of high-frequency acupoints and core prescriptions.Results(1)A total of 93 articles were included,including 117 acupuncture prescriptions and 172 acupoints,with a total frequency of 1 199 times of acupoints.(2)The top 10 acupoints were Fengchi(GB20),Zusanli(ST36),Hegu(LI4),Baihui(DU20),Sanyinjiao(SP6),Taichong(LR3),Quchi(LI11),Yanglingquan(GB34),Wangu(GB12),and Tianzhu(BL10).(3)The top five meridians used frequently were gallbladder meridian of foot shaoyang,governor vessel(GV),stomach meridian of foot yangming,large intestine meridian of hand yangming and bladder meridian of foot taiyang.(4)The selection of acupoints is mainly based on the head,face,neck and lower limbs.(5)The highest frequency of the use of specific points is the intersection point.(6)The high-frequency acupoints for acupuncture treatment of cerebellar ataxia are Fengchi-Wangu,Fengchi-Tianzhu and Fengchi-Tianzhu-Wangu.The top 31 high-frequency acupoints(frequency＞10 times)can be divided into nine effective clusters.Conclusion Acupuncture treatment for cerebellar ataxia has formed a compatibility rule with the main principle of"regulating the mind and constraining the bones,extinguishing wind and stopping the movement",with the far and near acupoints as the main body,and attaches importance to the application of yang meridians with multiple qi and blood,presenting the basic acupoint prescription with Fengchi-Wanggu-Tianzhu as the core.

Objective:To analyze the clinical characteristics,treatment,and prognosis of adult patients with early T-cell precursor acute lymphoblastic leukemia/lymphoma(ETP-ALL/LBL).Methods:Clinical data of 113 T lymphoblastic leukemia/lymphoma(T-ALL/LBL)patients from January 2006 to January 2019 were collected from three hematology research centers,including Peking University Third Hospital,the First Medical Center of Chinese PLA General Hospital and Institute of Hematology and Blood Diseases Hospital,Chinese Medical University.The clinical characteristics and prognosis of ETP-ALL/LBL patients were analyzed compared with non-ETP-ALL/LBL patients.Results:In 113 T-ALL/LBL patients,13 cases(11.5％)were diagnosed as ETP-ALL/LBL,including 11 males,with a median age of 28(18-53)years.Compared with non-ETP-ALL/LBL patients,there were no significant differences in age,sex,incidence of large mediastinal mass,clinical stage,international prognostic index(IPI)score,white blood cell(WBC)count and lactate dehydrogenase(LDH)level among ETP-ALL/LBL patients.Among 13 ETP-ALL/LBL patients,9 cases(69.2％)achieved complete remission(CR),and there was no statistically significant difference in response rate induced by chemotherapy between ETP-ALL/LBL patients and non-ETP-ALL/LBL patients.Among patients who received chemotherapy without allogeneic hematopoietic stem cell transplantation(allo-HSCT),ETP-ALL/LBL group had a worse 5-year overall survival(OS)rate compared with non-ETP-ALL/LBL group(0 vs 7.1％,P=0.008),while in patients with allo-HSCT,there was no significant difference for 5-year OS rate between the two group(37.5％vs 40.2％,P＞0.05).Multivariate Cox regression analysis showed that CR after induction therapy,allo-HSCT,and LDH level were independent prognostic factors affecting T-ALL/LBL patients.Conclusion:No significant difference in response rate induced by chemotherapy is observed between ETP-ALL/LBL and non-ETP-ALL/LBL patients.Allo-HSCT consolidation after induction of remission therapy may have significant favorable influence on OS for patients with ETP-ALL/LBL.

Objective:To summarize the clinical characteristics,therapeutic effect and prognostic factors of patients with Hodgkin's lymphoma(HL).Methods:A total of 129 patients with HL diagnosed in Peking University Third Hospital from January 2010 to March 2021 who were given at least one efficacy assessment after treatment were enrolled,and their clinical data,including sex,age,pathological type,Ann Arbor stage,ECOG score,blood test,β2-microglobulin,lactate dehydrogenase level,albumin level were collected.The clinical characteristics,therapeutic effect and long-term prognosis of the patients were summarized and analyzed.Results:In classical HL,nodular sclerosis HL accounted for the highest proportion of 51.6％,followed by mixed cellularity HL(36.5％),lymphocyte-rich classical HL(3.2％),and lymphocyte depletion HL(0.7％),while nodular lymphocyte predominant HL accounted for 4.8％.The 3-year overall survival(OS)rate of HL patients was 89.8％,and 5-year OS was 85.0％.The 3-year progression-free survival(PFS)rate was 73.4％,and 5-year PFS was 63.1％.Multivariate regression analysis indicated that IPI score was an independent negative factor,while hemoglobin(Hb)level was an independent positive factor for OS in HL patients.When the mediastinal mass size was 9.2 cm,it was most significant to judge the survival status of HL patients.5-year OS and 5-year PFS were 97.4％and 76.0％in early-stage HL patients without large mass,respectively,while in patients with advanced-stage HL was 83.4％and 55.9％(both P＜0.05).After 2-4 courses of treatment,the overall response rate(ORR)of patients who received chemotherapy combined with radiotherapy was 95.0％,while that was 89.6％in those with chemotherapy alone.Conclusions:The overall prognosis of patients with HL is satisfactory,especially those in early-stage without large mass.IPI score and Hb level are independent risk factors for the prognosis of HL patients.A 9.2 cm mediastinal mass can be used as the cut-off value for the prognosis of Chinese HL patients.

Objective:To investigate the effect of CD8+CD28-T cells on acute graft-versus-host disease(aGVHD)after haploidentical hematopoietic stem cell transplantation(haplo-HSCT).Methods:The relationship between absolute count of CD8+CD28-T cells and aGVHD in 60 patients with malignant hematological diseases was retrospectively analyzed after haplo-HSCT,and the differences in the incidence rate of chronic graft-versus host disease(cGVHD),infection and prognosis between different CD8+CD28-T absolute cells count groups were compared.Results:aGVHD occurred in 40 of 60 patients after haplo-HSCT,with an incidence rate of 66.67％.The median occurrence time of aGVHD was 32.5(20-100)days.At 30 days after the transplantation,the absolute count of CD8+CD28-T cells of aGVHD group was significantly lower than that of non-aGVHD group(P=0.03).Thus the absolute count of CD8+CD28-T cells at 30 days after transplantation can be used to predict the occurrence of aGVHD to some extent.At 30 days after transplantation,the incidence rate of aGVHD in the low cell count group(CD8+CD28-T cells absolute count＜0.06/μl)was significantly higher than that in the high cell count group(CD8+CD28-T cells absolute count ≥0.06/μl,P=0.011).Multivariate Cox regression analysis further confirmed that the absolute count of CD8+CD28-T cells at 30 days after transplantation was an independent risk factor for aGVHD,and the risk of aGVHD in the low cell count group was 2.222 times higher than that in the high cell count group(P=0.015).The incidence of cGVHD,fungal infection,EBV infection and CMV infection were not significantly different between the two groups with different CD8+CD28-T cells absolute count.The overall survival,non-recurrent mortality and relapse rates were not significantly different between different CD8+CD28-T cells absolute count groups.Conclusion:Patients with delayed CD8+CD28-T cells reconstitution after haplo-HSCT are more likely to develop aGVHD,and the absolute count of CD8+CD28-T cells can be used to predict the incidence of aGVHD to some extent.The absolute count of CD8+CD28-T cells after haplo-HSCT was not associated with cGVHD,fungal infection,EBV infection,and CMV infection,and was also not significantly associated with the prognosis after transplantation.
