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:To investigate the clinical efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC (albumin-bound paclitaxel + carboplatin) regimen in the treatment of advanced squamous non-small cell lung cancer (NSCLC) with driver gene negative and programmed death-1 receptor ligand 1 (PD-L1) expression positive.Methods:A prospective case-control study was performed. A total of 84 advanced squamous NSCLC patients with driver gene negative and PD-L1 expression positive in Hebei Seventh People's Hospital from January 2020 to December 2022 were collected, and all patients were divided into the observation group and the control group according to the random number table method, with 42 cases in each group. The control group was given the treatment of sintilimab combined with nab-PC regimen, and the observation group was given deep hyperthermia on the basis of the control group. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was compared. The levels of serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), cytokeratin fragment 19 (CYFR21-1)], and the positive expression rates of immunohistochemistry markers [p40, p63, and cytokeratin 5/6 (CK5/6)] before and after treatment were compared between two groups. Functional Assessment of Cancer Therapy-Lung cancer module (FACT-L) scores, the adverse reactions and the long-term survival of the two groups were compared.Results:There were 26 males and 16 females in the observation group, and the age was (59±11) years; there were 22 males and 15 females in the control group, and the age was (58±11) years. The objective remission rate and the disease control rate were 71.43% (30/42), 90.48% (38/42), respectively in the observation group, and 50.00% (21/42), 80.95% (34/42), respectively in the control group; the objective remission rate in the observation group was higher than that in the control group, and the difference was statistically significant ( χ2 = 4.04, P = 0.044); and there was no statistically significant difference in the disease control rate of both groups ( χ2 = 1.56, P = 0.212). The levels of serum CEA, SCCA and CYFRA21-1, and the positive expression rates of p40, p63, and CK5/6 in the two groups after treatment were lower than those before treatment (all P < 0.05); and the scores of physiological status, functional status, additional concern in FACT-L scores and the total score of the scale after treatment were higher than those before treatment (all P < 0.05). There were no statistically significant differences in the incidence of adverse reactions including thrombocytopenia, neutropenia, leukopenia, anemia, fever of the two groups (all P > 0.05). The median progression-free survival (PFS) time was 6.5 months (95% CI: 3.82-12.75), 5.1 months (95% CI: 3.14-12.26),respectively in the observation group and the control group, and the difference in the median PFS time was statistically significantly of both groups ( χ2 = 4.21, P = 0.040). The median overall survival (OS) time was 12.9 months (95% CI: 6.25-15.46), 9.7 months (95% CI: 4.74-13.02), respectively in the observation group and the control group, and the difference in the median OS time was statistically significantly of both groups ( χ2 = 4.43, P = 0.035). Conclusions:Deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous NSCLC with driver gene negative and PD-L1 expression positive can effectively reduce the serum tumor markers levels and positive expression rate of immunohistochemical markers, improve the quality of life of patients, and increase the short-term and long-term efficacy.

[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.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

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.
