Objective: To evaluate the safety and efficacy of ABO non-identical platelets with reduced plasma (ABO-NPRP) transfusion in patients with hematological diseases. Methods: A retrospective analysis was conducted on 52 therapeutic doses of apheresis platelets with reduced plasma prepared at Chongqing Blood Center of the Chinese People's Liberation Army. The transfusion efficacy (24 h CCI) and the transfusion adverse reactions of these apheresis platelets were also observed in 35 patients with hematological diseases in First Affiliated Hospital of Army Medical University. Comparisons were made with a control group consisting of patients who received only identical apheresis platelets during the same period. Meanwhile, the effect of ABO-NPRP on the subsequent platelet transfusion efficacy was observed. Results: There was no statistically significant difference in PDW, MPV, and PLCR before and after the preparation of apheresis platelets with reduced plasma (P>0.05), while the difference in platelet count was statistically significant [(2.86±0.34)×10 per therapeutic dose vs (2.46±0.28)×10 per therapeutic dose, P<0.001]; there was no statistically significant difference in the 24 h CCI transfusion efficacy between conventional identical apheresis platelets and ABO-NPRP, with transfusion efficacy rates of 76.60% and 78.85%, respectively (P>0.05); there was no statistically significant difference in platelet transfusion efficacy between the group with ABO-NPRP and the group without ABO-NPRP (completely identical transfusion group), with transfusion efficacy rates of 77.78% and 75.25%, respectively (P>0.05). Conclusion: ABO-NPRP transfusion is safe, effective, demonstrating comparable efficacy to conventional identical transfusion. It can serve as an important complementary strategy to optimize the utilization of blood resources.

Objective:To analyze the association between sleep status and ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.Methods:It was a cross sentional study. Hypertensive patients who underwent 24-hour ambulatory blood pressure monitoring from May 2021 to April 2023 in Shanghai Xinzhuang Town were enrolled. The demographic information and sleep status of patients were obtained from the questionnaire. A TM-2430 blood pressure monitor was used to measure 24-hour ambulatory blood pressure, and the relevant indicators, including blood pressure level and blood pressure coefficient of variation were documented. The association between sleep status and blood pressure indicators was analyzed with multivariate linear regression model.Results:A total 1 135 patients aged (65.07±12.61) years were enrolled, and 473 (41.67%) of whom were males. The sleep time was<7 hours in 76 cases, 7- 8 hours in 219 cases and >8 hours in 840 cases; the bedtime was earlier than 22∶00 in 415 cases, between 22∶00 and 23∶00 in 474 cases and later than 23∶00 in 246 cases; the wake-up time was before 6∶00 in 230 cases, between 6∶00 and 7∶00 in 521 cases and after 7∶00 in 384 cases. Multivariate linear regression analysis showed that after controlling for gender and age, the sleep time was negatively associated with diurnal, noctumal and 24-hour diastolic blood pressure levels (all P<0.05), and positively associated with diurnal and noctumal systolic blood pressure coefficient of variation, noctumal diastolic blood pressure coefficient of variation, and 24-hour systolic blood pressure coefficient of variation (all P<0.05).The bedtime was positively associated with diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), diastolic blood pressure (all P<0.05); and negatively associated with diurnal systolic blood pressure coefficient of variation, diurnal diastolic blood pressure coefficient of variation, noctumal systolic blood pressure coefficient of variation, 24-hour systolic blood pressure coefficient of variation, and 24-hour diastolic blood pressure coefficient of variation (all P<0.05). The wake-up time was positively associated with diurnal systolic blood pressure, diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), and positively associated with diurmal systolic blood pressure and diastolic blood pressure (both P<0.05). Conclusion:Sleep status is closely associated with ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.

Sphingomyelin phosphodiesterase 3 (SMPD3) encodes neutral sphingomyelinase 2 (nSMase2), which plays an important role in tumor development as a key enzyme regulating cell growth variation and inducing apoptosis with the important messenger molecule ceramide. On one hand, the common epigenetic alteration of SMPD3 methylation mediates carcinogenesis through the disruption of gene expression by regulating cell proliferation, differentiation, and apoptosis. Meanwhile, SMPD3 also induces apoptosis and cell cycle arrest in tumor cells through its hydrolysis products. On the other hand, SMPD3 is also closely related to pro-cancer processes such as exosome secretion, inflammatory response, and tumor cell proliferation. In this paper, the biological action of SMPD3 in tumor diseases was reviewed to enhance the understanding of the role of SMPD3 in the development of different tumors and provide broader ideas for basic research and clinical diagnosis and treatment of tumor diseases.

BACKGROUND: Inflammatory bowel disease (IBD) imposes a significant economic and social burden in China. We aim to assess the epidemiological trends of IBD in China, and to predict the burden in the near future. METHODS: The incidence, mortality, prevalence, and disability-adjusted life year (DALYs) of IBD from 1990 to 2021 were obtained from Global Burden of Disease Study 2021. Estimated annual percentage change (EAPC), average annual percent change, total percent change, and age-period-cohort model were used to access trends. Bayesian age-period-cohort model was utilized to predict the risk of incidence and mortality. RESULTS: In 2021, IBD affected 168,077 people in China, with 24,941 new cases and 5640 deaths. The age-standardized rate (ASR) of incidence and death was 1.4 and 0.3, respectively. The incidence and prevalence in China were lower than the global and high socio-demographic index (SDI) regions, but the ASR of incidence and prevalence (EAPC: 2.93 and 2.54, respectively) had rapidly increased from 1990 to 2021. The ASR of death and DALYs had significantly decreased (EAPC: -3.05 and -2.93, respectively). Middle-aged and elderly populations faced a severe burden of incidence and prevalence, while the elderly population faced a severe mortality burden. It is projected that by 2035, the ASR of incidence will continue to rise, whereas the death rate will continue to decline. CONCLUSIONS The burden of IBD in China is serious and increasingly severe. Establishing a comprehensive disease management system in China will help better control the medical burden of IBD.

OBJECTIVE: To develop monoclonal antibodies that can specifically recognize human von Willebrand factor (VWF) propeptide (VWFpp) in plasma, and establish a rapid and reliable method for the detection of VWFpp antigen in plasma by using the double-antibody sandwich ELISA with the obtained anti-VWFpp monoclonal antibody. METHODS: The recombinant human VWFpp (D1 and D2 regions) protein expressed in eukaryotic cells was used as immunogen to immunize BALB/c mice with routine method, so as to obtain clones of fusion cells. After screening and identification, hybridoma cell lines secreting monoclonal antibodies against VWFpp were selected, and then double-antibody sandwich ELISA assay was used to construct VWFpp antigen detection kit for the determination of VWFpp in human plasma. The levels of VWFpp antigen in plasma of 12 leukemia patients who underwent bone marrow transplantation were dynamically detected. RESULTS: Two hybridoma cell lines that can be subcultured continuously and secrete monoclonal antibodies against VWFpp were obtained and named SZ175 and SZ176 respectively. Identified by ELISA and Western blot, the antibodies could both specifically recognize VWFpp but couldn't recognize mature VWF (without propeptide). Based on the principle of double-antibody sandwich ELISA, monoclonal antibodies SZ175 and SZ176 were successfully made into a kit for detecting VWFpp antigen. The plasma VWFpp levels of leukemia patients before and after bone marrow transplantation were dynamically detected. The results showed that the plasma VWFpp levels of the patients after transplantation were significantly higher than those before transplantation. CONCLUSION Two monoclonal antibodies against VWFpp were successfully prepared, and a double-antibody sandwich ELISA detection kit for VWFpp antigen was constructed, which provides a powerful tool for further study on the biological function of VWFpp, the clinical diagnosis and classification of von Willebrand disease (VWD), and the prognostic monitoring of endothelial injury-related diseases.

OBJECTIVE: Jiedu Recipe (JR), a Chinese herbal remedy, has been shown to prolong overall survival time and decrease recurrence and metastasis rates in patients with hepatocellular carcinoma (HCC). This work investigated the mechanism of JR in HCC treatment. METHODS: The chemical constituents of JR were detected using liquid chromatography-mass spectrometry. The potential anti-HCC mechanism of JR was screened using network pharmacology and messenger ribonucleic acid (mRNA) microarray chip assay, followed by experimental validation in human HCC cells (SMMC-7721 and Huh7) in vitro and a nude mouse subcutaneous transplantation model of HCC in vivo. HCC cell characteristics of proliferation, migration and invasion under hypoxic setting were investigated using thiazolyl blue tetrazolium bromide, wound healing and Transwell assays, respectively. Image-iT™ Hypoxia Reagent was added to reveal hypoxic conditions. Stem cell sphere formation assay was used to detect the stemness. Epithelial-mesenchymal transition (EMT) markers like E-cadherin, vimentin and α-smooth muscle actin, and pluripotent transcription factors including nanog homeobox, octamer-binding transcription factor 4, and sex-determining region Y box protein 2 were analyzed using Western blotting and real-time polymerase chain reaction. Western blot was performed to ascertain the anti-HCC effect of JR under hypoxia involving the Wnt/β-catenin pathway. RESULTS: According to network pharmacology and mRNA microarray chip analysis, JR may potentially act on hypoxia and inhibit the Wnt/β-catenin pathway. In vitro and in vivo experiments showed that JR significantly decreased hypoxia, and suppressed HCC cell features of proliferation, migration and invasion; furthermore, the hypoxia-induced increases in EMT and stemness marker expression in HCC cells were inhibited by JR. Results based on the co-administration of JR and an agonist (LiCl) or inhibitor (IWR-1-endo) verified that JR suppressed HCC cancer stem-like properties under hypoxia by blocking the Wnt/β-catenin pathway. CONCLUSION JR exerts potent anti-HCC effects by inhibiting cancer stemness via abating the Wnt/β-catenin pathway under hypoxic conditions.

Objective:To investigate the clinical significance of color Doppler ultrasonography combined with detection of thyroid autoantibodies in the early diagnosis of thyroid cancer.Methods:A total of 108 patients with thyroid cancer who treated in Shaoxing Central Hospital Medical Community General Hospital from September 2019 to September 2021 were selected as the research group, and 108 patients with benign thyroid lesions during the same period were selected as the control group. The ultrasound examination results and the levels of serum thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb) and thyroid receptor antibody (TRAb) were compared between the two groups. The relationship between the thyroid autoantibodies index and the early diagnosis of thyroid cancer were analyzed by Spearman correlation analysis; the value of early diagnosis by color Doppler ultrasonography combined with detection of thyroid autoantibodies were evaluated by the receiver operating characteristic (ROC) curve.Results:The main features of ultrasonic images in the research group were unclear edge, low echo, irregular shape, chaotic blood flow distribution, internal micro calcification, no envelope and blood flow resistance index ≥0.7. The sensitivity of ultrasonography for the diagnosis of thyroid cancer was 86.11% (93/108), the specificity was 87.18% (102/117) and the accuracy was 90.28% (195/216). The levels of serum TgAb, TPOAb and TRAb in the research group were higher than those in control group: (32.28 ± 2.85) kU/L vs. (21.96 ± 2.54) kU/L, (81.28 ± 7.32) kU/L vs. (51.53 ± 5.86) kU/L, (4.48 ± 1.25) U/L vs. (2.35 ± 0.63 ) U/L, there were statistical differences ( P<0.05). The levels of serum TgAb, TPOAb and TRAb in patients with lymph node metastasis were higher than those in the patients without lymph node metastasis: (36.28 ± 3.12) kU/L vs. (30.60 ± 2.54) kU/L, (93.51 ± 8.57) kU/L vs. (76.13 ± 6.62) kU/L, (5.73 ± 1.54) U/L vs. (3.95 ± 1.12) U/L, there were statistical differences ( P<0.05). The levels of serum TgAb, TPOAb and TRAb in patients with stage Ⅲ-Ⅳ were higher than those in the patients with stage Ⅰ-Ⅱ: (35.84 ± 3.28) kU/L vs. (29.74 ± 2.29) kU/L, (89.35 ± 8.16) kU/L vs. (75.52 ± 6.23) kU/L, (5.28 ± 1.49) U/L vs. (3.91 ± 1.25) U/L, there were statistical differences ( P<0.05). The results of Spearman correlation analysis showed that the levels of serum TgAb, TPOAb and TRAb were positively correlated with lymph node metastasis ( r = 0.758, 0.824, 0.695, P<0.05) and clinical stage of thyroid cancer ( r = 0.735, 0.796, 0.673, P<0.05). The results of ROC curve analysis showed that the area under the curve(AUC) of ultrasound examination combined with TgAb, TPOAb and TRAb for early diagnosis of thyroid cancer was 0.930, the sensitivity was 85.19%, and the specificity was 91.67%. The combined diagnostic value was better than single diagnosis. Conclusions:Ultrasound examination combined with serum TgAb, TPOAb and TRAb has high diagnostic value for early stage thyroid cancer, which is helpful to clinically clarify the condition, and provides a reliable basis for preoperative diagnosis and targeted individualized treatment plan.

Objective:To explore the risk factors of microvascular invasion (MVI) in hepatocellular carcinoma (HCC), and to predict MVI preoperatively, non-invasively and accurately.Methods:A total of 150 HCC patients (183 HCC lesions) were retrospectively collected in the First Affiliated Hospital of Xi′an Jiaotong University from January 2016 to June 2022.The clinical data and hematological data, gray-scale ultrasonography (US), contrast-enhanced ultrasonography (CEUS), enhanced magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (EOB-MRI) and pathological data of these patients were recorded. According to the pathological diagnosis of MVI, the lesions were divided into MVI (+ ) group and MVI (-) group. The indicators between the two groups were compared. All 183 lesions were put into the training set, and the prediction model with nomogram was constructed according to the risk factors of MVI selected by multivariate Logistic regression. The internal verification was carried out by ten-fold cross-validation method.Results:There were significant statistical differences in the following parameters between MVI (+ ) group ( n=109) and MVI (-) group ( n=74) (all P<0.05). These were cirrhosis, serological parameters (alpha-fetoprotein, albumin, total bilirubin), qualitative indexes of US (size, boundary, internal echo), qualitative indexes of CEUS (hyper/iso/hypovascularity of lesions in arterial phase, portal phase, and delayed phase compared with hepatic parenchyma), and quantitative indexes of EOB-MRI [post enhancement rate (post ratio) and gadolinium disodium rate (EOB ratio)] calculated mainly in terms of lesions and surrounding liver parenchyma in hepatobiliary phase and unenhanced T1 images). Finally, cirrhosis of patients, the size, boundary, internal echo of lesions in US; arterial phase (AP), portal phase (PP), post-vascular phase (PVP) features in CEUS; the EOB rate and post rate of EOB-MRI entered the prediction model of MVI. The training set exhibited good calibration and net gain rate. The areas under the ROC curve for the training set and the validation set were 0.981 and 0.961, respectively, while the diagnostic accuracy were 92.9% and 85.8%, respectively. Conclusions:The model constructed mainly by multimodality imaging methods can achieve favorable predictive performance for MVI, which provides valuable ideas for noninvasively predicting the incidence of MVI and optimizing the MVI-related treatment of MVI in HCC patients.

Objective: To report the clinical manifestations and laboratory features of five patients with congenital thrombotic thrombocytopenic purpura (cTTP) and explore its standardized clinical diagnosis and treatment along with a review of literature. Methods: Clinical data of patients, such as age of onset, disease manifestation, personal history, family history, and misdiagnosed disease, were collected. Treatment outcomes, therapeutic effects of plasma infusion, and organ function evaluation were observed. The relationship among the clinical manifestations, treatment outcomes, and ADAMTS13 gene mutation of patients with cTTP was analyzed. Additionally, detection of ADAMTS13 activity and analysis of ADAMTS13 gene mutation were explored. Results: The age of onset of cTTP was either in childhood or adulthood except in one case, which was at the age of 1. The primary manifestations were obvious thrombocytopenia, anemia, and different degrees of nervous system involvement. Most of the patients were initially suspected of having immune thrombocytopenia. Acute cTTP was induced by pregnancy and infection in two and one case, respectively. ADAMTS13 gene mutation was detected in all cases, and there was an inherent relationship between the mutation site, clinical manifestations, and degree of organ injury. Therapeutic or prophylactic plasma transfusion was effective for treating cTTP. Conclusions: The clinical manifestations of cTTP vary among individuals, resulting in frequent misdiagnosis that delays treatment. ADAMTS13 activity detection in plasma and ADAMTS13 gene mutation analysis are important bases to diagnose cTTP. Prophylactic plasma transfusion is vital to prevent the onset of the disease.
