The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Objective To evaluate the characteristics of different antigen-specific T cell immune responses to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)after inoculation with 2 doses of SARS-CoV-2 inactivated vaccine for 12 months.Methods Fifteen healthy adults were enrolled in this study and blood samples collected at 12 months after receiving two doses of SARS-CoV-2 inactivated vaccine.The level and phenotypic characteristics of SARS-CoV-2 antigen-specific T lymphocytes were detected by activation-induced markers(AIM)based on polychromatic flow cytometry.Results After 12 months of inoculation with 2 doses of SARS-CoV-2 inactivated vaccine,more than 90%of adults had detectable Spike and Non-spike antigen-specific CD4+ T cells immune responses(Spike:14/15,P=0.0001;Non-spike:15/15,P<0.0001).80%of adults had detectable Spike and Non-spike antigen-specific CD8+ T cells immune responses(Spike:12/15,P=0.0463;Non-spike:12/15,P=0.0806).Antigen-specific CD4+ T cells induced by SARS-CoV-2 inactivated vaccination after 12 months were composed of predominantly central memory(CM)and effector memory 1(EM1)cells.On the other hand,in terms of helper subsets,antigen-specific CD4+ T cells mainly showed T helper 1/17(Th1/17)and T helper 2(Th2)phenotypes.Conclusions SARS-CoV-2 inactivated vaccination generates durable and extensive antigen-specific CD4+ T cell memory responses,which may be the key factor for the low proportion of severe coronavirus disease 2019(COVID-19)infection in China.

Objective: To assess the feasibility of using donors with novel coronavirus disease 2019 (COVID-19) for allogeneic hematopoietic stem cell transplantation (allo-HSCT) when there are no other available donors and allo-HSCT cannot be delayed or discontinued. Methods: Seventy-one patients with malignant hematological diseases undergoing allo-HSCT between December 8, 2022, and January 10, 2023, were included. Of these, 16 received grafts from donors with mild COVID-19 (D-COVID(+) group) and 55 received grafts from donors without COVID-19 (D-COVID(-) group). The graft compositions were compared between the two groups. Engraftment, acute graft-versus-host disease (aGVHD), overall survival (OS), and relapse were also evaluated. Results: There were no serious side effects or adverse events in the D-COVID(+) group. The mononuclear cell dose and CD34(+) cell dose were comparable between the two groups, and no additional apheresis was required. There were no significant differences in the lymphocyte, monocyte, and T-cell subset doses between the two groups. The median natural killer cell dose in the D-COVID(+) group was significantly higher than that in the D-COVID(-) group (0.69×10(8)/kg vs. 0.53×10(8)/kg, P=0.031). The median follow-up time was 72 (33-104) days. All patients achieved primary engraftment. The 60-day platelet engraftment rates in the D-COVID(+) and D-COVID(-) groups were 100% and (96.4±0.2) %, respectively (P=0.568). There were no significant differences in neutrophil (P=0.309) and platelet (P=0.544) engraftment times. The cumulative incidence of grade 2-4 aGVHD was (37.5±1.6) % vs. (16.4±0.3) % (P=0.062), and of grade 3-4 aGVHD was 25.0% ±1.3% vs. 9.1% ±0.2% (P=0.095) in the D-COVID(+) and D-COVID(-) groups, respectively. The probabilities of 60-day OS were 100% and 98.1% ±1.8% (P=0.522) in the D-COVID(+) and D-COVID(-) groups, respectively. There was no relapse of primary disease during the study period. Conclusion: When allo-HSCT cannot be delayed or discontinued and no other donor is available, a donor with mild COVID-19 should be considered if tolerable. Larger sample sizes and longer follow-up periods are required to validate these results.

Aim To investigate the effect of microinjection of EX527, a selective SIRT1 antagonist, into the ventrolateral orbital cortex (VLO) on morphine-induced conditioned place preference (CPP), and to explore the role of CREB/BDNF in it. Methods The cannulas were implanted bilaterally in the VLO of rats by brain stereotaxis surgery, and the model of morphine-induced CPP was established. The behavioral experiment consisted of four stages:habituation (d 1), pre-test (d 2-4), conditioning training (d 5-14) and test (d 15). At the stage of conditioning training, EX527 (1 μL, 5 g·L

OBJECTIVES: To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma. METHODS: This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis. RESULTS: The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686). CONCLUSIONS AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

Objective:To explore the association between atypical small acinar proliferation(ASAP)and subsequent diagnosis of intermediate and high risk prostate cancer(PCa),and analyze whether delaying repeat biopsy timing is safe and effective.Meth-ods:From June 2000 to June 2022,we retrospectively analyzed the clinical data of 276 patients accepting prostatic biopsy and diag-nosed with ASAP in China-Japan Union Hospital of Jilin University.54.7％(151/276)patients had a repeat biopsy.We used statis-tic methods to process the data.Results:25.2％(38/151)patients were diagnosed with PCa on repeat biopsy.Among them,78.9％(30/38)patients had Gleason score(GS)3+3 and 21.1％(8/38)had GS 3+4 disease.There were 4 and 6 patients got RP re-spectively in the two cohorts.Only 5.3％(8/151)of ASAP patients were diagnosed as intermediate risk PCa in repeated biopsy and specially,no high risk PCa was identified in our study.Conclusion:It was safe and valid to delay the repeat biopsy.

Objective:To investigate Chinese myocarditis burden and trends in 1990 and 2019.Methods:Based on the Global Burden of Disease (GBD) 2019 data, the number of patients, the number of new cases, the number of deaths, the disability-adjusted life years (DALYs), as well as the morbidity, mortality, DALYs rate and their age-standardized rates were used to analyze the trend and the burden of myocarditis in the Chinese population in 1990 and 2019.Results:In 2019, the number of patients, the number of new cases and the number of deaths with myocarditis in China were 234 900, 275 100 and 13 100 respectively, increasing by 85.62%, 47.51% and 50.22% compared with 1990. The age-standardized incidence and mortality were 16.94/100 000 and 0.92/100 000, respectively. Compared with 1990, the age-standardized incidence in 2019 decreased by 6.06%, and the mortality decreased by 16.04% respectively. The age-standardized incidence and mortality of Chinese male patients with myocarditis were higher than that of female. Compared with 1990, the age group with the largest incidence and mortality of myocarditis in China in 2019 all shifted to the elder group. And, DALYs and age-normalized DALYs due to myocarditis in China showed a decreasing trend in 2019, from 458 600 and 42.51/100 000 in 1990 to 341 300 and 25.39/100 000 in 2019, respectively. The rate of DALYs and age-standardized DALYs in male patients was always higher than female.Conclusions:Compared with 1990, the overall burden of myocarditis in China showed a downward trend in 2019, and the burden of myocarditis in male patients was higher than female. More attention should be paid to the burden of myocarditis in Chinese elderly population.

Aim To investigate the reeovery of I FN-7- tion and the protective effect of Prepared Radix Reh- secreting T and NK cells after low dose X-ray irradia- manniae ( PRR ).Methods X-ray 2.5Gy was used to establish a mouse irradiated model,and some irradiated mice were used to establish a melanoma lung cancer metastasis model or to be treated by PRR.The propor¬tion and number of Tel , Thl and NK1 cells with the phenotypes of IL-12R and IL-15R were detected by flow cytometry.The transcription levels of IL-12,1L- 15 ,STAT4 and T-bet were detected by RT-qPCR.Re¬sults Within four days after irradiation,Thl ,Tcl and NK1 cells were significantly reduced ( P < 0.05 , P < 0.01).The expression of IL-12R and IL-15R de¬creased in Thl and Tel cells , and increased in NK1 cells ( P < 0.05 ).On day 8 of irradiation , NK1 and Tc 1 cells recovered or exceeded basic level, but Th 1 was still lower than normal level ( P < 0.05 ) , and tumor load of irradiated mice increased significantly (P <0.01).Compared with radiation group, the propor¬tion and absolute numbers of NK1 ,Tel and Thl were up-regulated by PRR (P <0.05 <0.01) ,and tumor load was down-regulated ( P < 0.05 ).Conclusions The impaired reconstitution of Thl cells after irradia¬tion affects the anti-tumor ability.PRR promotes the recover}' of IFN-∗y-secreting T and NK cells after radia¬tion and reduces the risk of tumor metastasis in mice.

Aim To explore and optimize the different separation and purification methods of neural stem cells (NSCs) , and compare the cell viability and purity after separation and purification.Methods (X) Separation of NSCs: The brains of ICR mice born within 24 h were isolated ( the cerebellum and olfactory bulb removed) , chopped and digested by mechanical pipetting, trypsin digestion, and PDD enzyme digestion.After sieving and centrifugation, the brain tissues were inoculated at a concentration of 1 X 10 • L , and cultured in serum-free medium to observe and compare the activity, proliferation and number of miscellaneous cells.(2) Purification of NSCs: The brain tissues of mice born within 24 h were isolated, and NSCs were purified by differential centrifugation and sieving, and the purity was identi-fied by immunofluorescence.Results NSCs separated by PDD enzyme digestion had high survival rate and rapid proliferation rate; the Nestin positive rate of NSCs in both Sieving assay and Differential centrifugation assay groups was higher than that of primary NSCs (59.14% ± 0.16% , P <0.05) , and the former (93.54% ± 0.02%) was higher than the latter (86.12% ± 0.04% ) .Conclusions The three separation methods can obtain a large amount of NSCs.Among them, the PDD enzymatic digestion method has little damage to the NSCs, and the neuro-sphere proliferation speed is fast; the NSCs obtained by the sieving assay have higher purity.
