Hematologic malignancies,such as lymphoma,myeloma,and myeloid neoplasms,can occur in extramedullary tissues.Traditional histopathological morphology and immunohistochemical staining have lim-itations,including time-consuming specimen processing,prolonged reporting cycles,and relatively low sensi-tivity in cases of limited cell numbers.Flow cytometry offers significant advantages in detecting tissue sam-ples,such as rapid processing,shorter reporting cycles,and high accuracy and sensitivity,making it an effective complement to histopathological and immunohistochemical methods.However,the application of flow cytome-try in tissue sample detection currently lacks standardized protocols for sample collection and preservation,single-cell suspension preparation,antibody panel design for limited samples,data analysis,and result repor-ting.To promote the standardized application of flow cytometry in detecting hematologic tumor cells in tissue samples,the Cell Analysis Professional Committee of the Chinese Society of Biotechnology organized experts to develop the Chinese Expert Consensus on Flow Cytometry for Detecting Hematologic Tumor Cells in Tis-sue Samples(hereinafter referred to as the Consensus).This Consensus elaborates on the technical aspects of flow cytometry for tissue sample detection,covering sample processing,antibody panel design,data analysis,reporting content,and quality management.It particularly emphasizes recommended antibody panels and data analysis methods for flow cytometry when tissue sample cell counts are low.This article aims to interpret the key points of the Consensus to facilitate its better application in clinical practice.

Objective To observe the clinical efficacy of Fuyuan Capsules combined with Xingnao Kaiqiao acupuncture in the treatment of vascular dementia(VD),and to explore its possible mechanism of action.Methods A total of 204 cases of patients with a definitive diagnosis of VD admitted to the wards and outpatient clinics of Hengshui Hospital of Traditional Chinese Medicine from October 2019 to October 2022 were selected for the study.The patients were randomly divided into observation group and control group according to the random number table method,with 102 cases in each group.The patients in both groups were treated with symptomatic treatments such as blood pressure-controlling,glucose-lowering,blood lipids-regulating,along with cognitive function training.The control group was treated with Xingnao Kaiqiao acupuncture,and the observation group was given oral administration of Fuxing Capsules on the basis of the treatment in the control group.One week constituted a course of treatmen,and eight consecutive courses of treatment were carried out.After two months of treatment,the clinical efficacy of the two groups was evaluated.The changes in the scores of the Mini-Mental State Examination(MMSE),Montreal Cognitive Assessment(MoCA),Revised Hasegama's Dementia Scale(HDS-R),and Clinical Dementia Rating Scale(CDR)were observed in the patients of the two groups before and after treatment.The changes in the scores of the Activity of Daily Living Scale(ADL),Hachinski Ischemic Scale(HIS),and the traditional Chinese medicine(TCM)syndrome scores before and after treatment were compared in patients of the two groups.The changes in the expression level of neuregulin 1(NRG1)before and after treatment in patients of the two groups were detected.Results(1)During the study,two cases fell off from both groups,respectively.Finally,100 cases in the observation group and 100 cases in the control group were included in the efficacy statistics.(2)After treatment,the MMSE and MoCA scores of the patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(3)After treatment,the HDS-R and CDR scores of patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(4)After treatment,the ADL and HIS scores of patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(5)After treatment,the TCM syndrome scores of patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(6)The total effective rate was 84.00％(84/100)in the observation group and 67.00％(67/100)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P＜0.05).(7)After treatment,the NRG1 levels of patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).Conclusion Fuyuan Capsules combined with Xingnao Kaiqiao acupuncture in the treatment of VD can significantly improve the clinical symptoms of patients,enhance the cognitive function,and effectively increase the serum NRG 1 level,so as to improve their quality of life.

Objective To investigate the association between healthy lifestyle factors and cardiovascular biological aging,as well as the relative contributions of different lifestyle factors.Methods Based on the clinical biochemical data and anthropometric data from the baseline survey of the UK Biobank(UKB),the Klemera-Doubal method(KDM)was used to establish cardiovascular biological age(CBA),and CBA acceleration was calculated accordingly.Multiple linear regression models were used to estimate the associations between healthy lifestyle factors and CBA acceleration.Then,the Quantile g-computation(QGC)was applied to evaluate the relative contributions of different lifestyle factors to CBA acceleration,with further analyses conducted separately for male and female populations.Additionally,stratified analyses were performed based on age,sex,body mass index(BMI),racial background,and family history of cardiovascular diseases to examine population heterogeneity.Results A total of 251 478 participants were included in the study.Both the overall healthy lifestyle score and each of the 7 lifestyle factors were negatively associated with CBA acceleration(overall lifestyle score:β=-0.75,95%CI:-0.77 to-0.73).Regarding the relative contributions of different lifestyle factors,alcohol consumption and diet accounted for the highest proportions(25.8%and 25.7%,respectively).However,there were differences by sex—alcohol consumption contributed the most in men(29.5%),followed by diet(23.0%),while in women,diet contributed the most(34.5%)and alcohol consumption accounted for a relatively low proportion(5.5%).Stratified analyses suggested that sex,BMI,and race might be potential effect modifiers.Conclusion Lifestyle factors,as modifiable behaviors,can slow the rate of cardiovascular biological aging.Among these factors,alcohol consumption and diet may represent effective targets for intervention.

Objective To evaluate the application of shear wave elastography(SWE)in the diagnosis of peripheral neuropathy in patients with diabetes.Methods Totally 85 patients with type 2 diabetes(T2DM)were selected from the Chengdu Office Hospital of People's Government of Tibetan Autonomous Region,including 46 patients with peripheral neuropathy(DPN)and 39 patients without peripheral neuropathy(NDPN).Compared for clinical data(gender,age,disease duration),cross-sectional area of the median nerve measured by high-frequency ultra-sound(CSA)and shear wave elastography(SWE)parameters(mean Young's modulus value,Emean)and shear wave velocity(SWV)between two groups of patients.Multifactor Logistic regression analysis was carried out on the indicators between the above groups to screen independent predictors in the diagnosis of peripheral neuropathy in diabetes patients,and a combined model was constructed.The area under the operating characteristic curve(AUC),sensitivity and specificity of the subjects were used to evaluate the diagnostic efficacy of the single model and com?bined model of the quantitative parameters(CSA,Emean,SWV)measured by clinical data,high?frequency ultra?sound and SWE in the diagnosis of peripheral neuropathy in diabetes patients.Results Age,course of disease,Emean,SWV and CSA were statistically significant in the diagnosis of peripheral neuropathy in diabetes patients(all P<0.05).AUC was 0.658,0.754,0.839,0.822 and 0.736,respectively.The combination model based on disease course,CSA and SWV showed the highest diagnostic efficiency,with AUC,sensitivity,and specificity of 0.887(0.800-0.946),80.43％,and 84.62％,respectively.Conclusions The combined model based on the course of disease,CSA and SWV have a high diagnostic efficiency in peripheral neuropathy of diabetes patients,and has good clinical application value.

Objective:This study aims to explore the survival advantages of different maintenance strategies for MCL.Methods:Clinical data of 693 newly diagnosed MCL patients in multi-centers admitted from April 1999 to December 2019 were collected. 309 cases received maintenance treatment. The characteristics of patients in different maintenance treatment groups were summarized and Kaplan-Meier survival and prognosis analysis were conducted.Results:The overall 3-year and 5-year progression-free survival (PFS) rates were (73.5±2.9) % and (53.6±4.3) %, respectively. The 3-year and 5-year overall survival (OS) rates were (94.2±1.5) % and (82.7±3.2) %, respectively. The clinical features of different maintenance treatment groups were generally consistent. The 3-year PFS rates of rituximab maintenance, lenalidomide maintenance, BTK inhibitor maintenance and dual-drug maintenance were (70.4±4.1) %, (69.1±7.6) %, (86.9±5.0) %, and (80.4±5.1) %, respectively. Corresponding 3-year OS rates were (92.9±2.4) %, (97.3±2.7) %, (97.9±2.1) %, and (95.3±2.7) %, respectively. There were no significant difference in different groups ( P=0.632, 0.313). Survival analysis identified the MCL International Prognostic Index (MIPI) high-risk group and achieving complete remission before maintenance treatment as independent risk factors for PFS. The MIPI high-risk group, high-dose cytarabine application, treatment lines, and early disease progression (POD24) emerged as independent risk factors for OS. Conclusion:Comparing the different maintenance strategies of MCL, the result showed that BTK inhibitors (BTKi) maintenance demonstrated preliminary advantages in survival. Meanwhile, high-risk group according to MIPI and incomplete remission before maintenance treatment were significant factors related to disease progression.

Objective:To analyze the factors affecting delayed chemotherapy in children with Burkitt lymphoma (BL) and their influence on prognosis.Methods:Retrospective cohort study. Clinical data of 591 children aged ≤18 years with BL from May 2017 to December 2022 in China Net Childhood Lymphoma (CNCL) was collected. The patients were treated according to the protocol CNCL-BL-2017. According to the clinical characteristics, therapeutic regimen was divided into group A, group B and group C .Based on whether the total chemotherapy time was delayed, patients were divided into two groups: the delayed chemotherapy group and the non-delayed chemotherapy group. Based on the total delayed time of chemotherapy, patients in group C were divided into non-delayed chemotherapy group, 1-7 days delayed group and more than 7 days delayed group. Relationships between delayed chemotherapy and gender, age, tumor lysis syndrome before chemotherapy, bone marrow involvement, disease group (B/C group), serum lactate dehydrogenase (LDH) > 4 times than normal, grade Ⅲ-Ⅳ myelosuppression after chemotherapy, minimal residual disease in the interim assessment, and severe infection (including severe pneumonia, sepsis, meningitis, chickenpox, etc.) were analyzed. Logistic analysis was used to identify the relevant factors. Kaplan-Meier method was used to analyze the patients' survival information. Log-Rank was used for comparison between groups.Results:Among 591 patients, 504 were males and 87 were females, the follow-up time was 34.8 (18.6,50.1) months. The 3-year overall survival (OS) rate was (92.5±1.1)%,and the 3-year event-free survival (EFS) rate was (90.5±1.2)%. Seventy-three (12.4%) patients were in delayed chemotherapy group and 518 (87.6%) patients were in non-delayed chemotherapy group. The reasons for chemotherapy delay included 72 cases (98.6%) of severe infection, 65 cases (89.0%) of bone marrow suppression, 35 cases (47.9%) of organ dysfunction, 22 cases (30.1%) of tumor lysis syndrome,etc. There were 7 cases of chemotherapy delay in group B, which were seen in COPADM (vincristine+cyclophosphamide+prednisone+daunorubicin+methotrexate+intrathecal injection,4 cases) and CYM (methotrexate+cytarabine+intrathecal injection,3 cases) stages. There were 66 cases of chemotherapy delay in group C, which were common in COPADM (28 cases) and CYVE 1 (low dose cytarabine+high dose cytarabine+etoposide+methotrexate, 12 cases) stages. Multinomial Logistic regression analysis showed that the age over 10 years old ( OR=0.54,95% CI 0.30-0.93), tumor lysis syndrome before chemotherapy ( OR=0.48,95% CI 0.27-0.84) and grade Ⅲ-Ⅳ myelosuppression after chemotherapy ( OR=0.55,95% CI 0.33-0.91)were independent risk factors for chemotherapy delay.The 3-year OS rate and the 3-year EFS rate of children with Burkitt lymphoma in the delayed chemotherapy group were lower than those in the non-delayed chemotherapy group ((79.4±4.9)% vs. (94.2±1.1)%, (80.2±4.8)% vs. (92.0±1.2)%,both P<0.05). The 3-year OS rate of the group C with chemotherapy delay >7 days (42 cases) was lower than that of the group with chemotherapy delay of 1-7 days (22 cases) and the non-delay group (399 cases) ((76.7±6.9)% vs. (81.8±8.2)% vs. (92.7±1.3)%, P=0.002).The 3-year OS rate of the chemotherapy delay group (9 cases) in the COP (vincristine+cyclophosphamide+prednisone) phase was lower than that of the non-chemotherapy delay group (454 cases) ((66.7±15.7)% vs. (91.3±1.4)%, P=0.005). Similarly, the 3-year OS rate of the chemotherapy delay group (11 cases) in the COPADM1 phase was lower than that of the non-chemotherapy delay group (452 cases) ((63.6±14.5)% vs. (91.5±1.3)%, P=0.001). Conclusions:The delayed chemotherapy was related to the age over 10 years old, tumor lysis syndrome before chemotherapy and grade Ⅲ-Ⅳ myelosuppression after chemotherapy in pediatric BL. There is a significant relationship between delayed chemotherapy and prognosis of BL in children.

Coronary artery calcifications (CAC) is an independent risk factor for cardiovascular disease (CVD). It has been revealed that this condition can be automatically quantified through computerize tomographic (CT) scan contained in radiotherapy plan for patients with breast cancer, with which, physicians can identify the patients with increased risk of CVD after radiotherapy prematurely and take intervention measures in advance. In this article, the current literature and research progress on the correlation between CAC and cardiotoxicity in patients with breast cancer after radiotherapy were reviewed, expecting to provide a strategy to reduce the CVD risk in patients with breast cancer after radiotherapy.

[Abstract] [Objective] To analyze the detection ability of one imported and three domestic microcolumn agglutination anti-human globulin cards in unexpected antibody screening test. [Methods] A total of 104 positive samples from antibody screening test conducted at our hospital from July to September 2022 were selected. Microcolumn agglutination antiglobulin tests were performed in parallel with antibody screening tests using one imported card (A Card) and three domestic cards (B, C and D Cards ) to analyze the differences in the sensitivity, specificity and agglutination intensity scores. [Results] The sensitivity of the four anti-human globulin cards was as follows: D card 88.51% (131/148) > C card 83.22% (124/149) > B card 81.63% (120/147) > A card 80.54% (120/149); the specificity was A card 97.79% (133/136) > B card 95.65% (132/138) > D card 95.62% (131/137) > C card 93.38% (127/136); and the average agglutination intensity score (points) was D card 214.57 > C card 191.90 > A Card 179.69 > B Card 175.83, and the H value of Kruskal-Wallis test was 7.221, with no statistically significant difference (P > 0.05). Among them, C card was prone to false positives, accounting for 3.16% (9/285), and A card was prone to false negatives, accounting for 10.18% (29/285). [Conclusion] There were differences in the detection ability of anti-human globulin cards of different manufacturers, and some domestic cards have higher detection performance than imported cards. It is recommended to use anti-human globulin cards of two manufacturers routinely in clinical practice, that is, to use cards with high detection sensitivity for antibody screening tests to avoid antibody missed detection as much as possible, and to use cards with high specificity for cross-matching blood tests to avoid delays in transfusion due to false positives, which could hinder transfusion treatment.
