With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

Testicular radiation injury is a structural and functional abnormality of the testes caused directly or indirectly by radiation, which disrupts spermatogenesis and compromises male fertility. The development of effective preventive and therapeutic interventions is essential because of the high prevalence of this condition in clinical settings and its profound effect on patients′ reproductive health and overall well-being. The concept of "the struggle between vital qi and pathogen" is first seen in the Treatise on Cold Pathogenic Diseases. It denotes the dynamic struggle between vital and pathogenic qi. The occurrence, development, and sequelae of all diseases reflect this ongoing conflict. In this context, this study defines the "vital qi" of the testis as its capacity to generate and preserve the essence of reproduction and to resist damage. The pathogenic qi associated with testicular radiation injury is categorized into two types: ionizing poison and retaining evil. The pathogenesis of testicular radiation damage is delineated into three stages by integrating the characteristics of vital and pathogenic qi: the injury, adhesion, and recovery phases. Based on the theoretical framework advanced by this study, the therapeutic approach for testicular radiation injury should adhere to the fundamental principle of strengthening vital qi and eliminating pathogenic factors. Although the primary focus of treatment should be on strengthening vital qi, it should also be complemented by strategies to eliminate pathogenic influences. This paper aims to provide a novel perspective and strategic approach to the traditional Chinese medicine diagnosis, prevention, and treatment of testicular radiation injury. By elucidating the process of testicular radiation injury and its corresponding treatment principles, it seeks to offer valuable insights for clinical practice.

Objective:To analyze the changing trends and international differences in the incidence and disability-adjusted life years (DALY) of hypertensive disorders in pregnancy (HDP) in China from 1990 to 2021 based on the Global Burden of Disease (GBD) database.Methods:The data were derived from the GBD database, covering the incidence and DALY data of HDP in countries or regions around the world. Descriptive statistics were used to compare the differences in disease burden between China and different regions of Europe, America and other developed countries, and to analyze the disease burden characteristics of women of childbearing age in different age groups (every 5 years). The Joinpoint regression model was used to identify trend change points. The age-period-cohort model was used to analyze the independent effects of age, period and birth cohort.Results:(1) From 1990 to 2021, the incidence of HDP in China showed an overall downward trend, from 387.18/100 000 in 1990 to 216.35/100 000 in 2021. Compared with the global incidence rate (1990: 1 167.28/100 000; 2021: 923.48/100 000), the incidence rate of HDP in China was relatively low, but it was still higher than that in some developed countries. (2) The analysis of the Joinpoint regression model showed that the incidence rate of HDP in different age groups first decreased, then increased, and finally leveled off. The connection point with the lowest point was in 2005. DALY showed a continuous downward trend in all age groups. Among them, the decline in maternal DALY of pregnant women in all age groups from 15 to 39 years old was more obvious. (3) The age-period-cohort effect model showed that the incidence rate and DALY of HDP in women of childbearing age aged 20 to 24 years reached their peak.Conclusions:The burden of HDP in China continues to decrease, and the disease prevention and control has achieved remarkable results, but the incidence rate is still higher than that in some developed countries. It is suggested that personalized interventions should be developed for different risk groups to further reduce the burden of disease.

Background::Chemotherapy plus granulocyte colony-stimulating factor (GCSF) regimen is one of the available approaches to mobilize peripheral blood progenitor cells (PBPCs). It causes thrombocytopenia and delays leukapheresis. This study aimed to evaluate the role of recombinant human thrombopoietin (rhTPO) before mobilization chemotherapy in facilitating leukapheresis in patients with lymphoma.Methods::In this randomized open-label phase 2 trial, patients were randomly assigned in a 1:2 ratio to receive mobilization with rhTPO plus GCSF in combination with chemotherapy (the rhTPO plus GCSF arm) or GCSF alone in combination with chemotherapy (the GCSF alone arm). The recovery of neutrophils and platelets and the amount of platelet transfusion were monitored.Results::Thirty patients were enrolled in this study between March 2016 and August 2018. Patients in the rhTPO plus GCSF arm (n = 10) had similar platelet nadir after mobilization chemotherapy ( P=0.878) and similar amount of platelet transfusion (median 0 vs. 1 unit, P=0.735) when compared with the GCSF alone arm (n = 20). On the day of leukapheresis, the median platelet count was 86 × 10 9/L (range 18-219) among patients who received rhTPO and 73 × 10 9/L (range 42-197) among those who received GCSF alone ( P=0.982). After the use of rhTPO, the incidence of platelet count <75 × 10 9/L on the day of leukapheresis did not decrease significantly (30.0% vs. 50.0%, P=0.297). Platelet recovery after PBPC transfusion was more rapid in the rhTPO plus GCSF arm (median 8.0 days [95% confidence interval 2.9-13.1] to platelets ≥50 × 10 9/L vs. 11.0 days [95% confidence interval 8.6-13.4], P=0.011). The estimated total cost of the mobilization and reconstitution phases per patient was similar between the two treatmtent groups ( P=0.362 and P=0.067, respectively). Conclusions::Our findings indicate that there was no significant clinical benefit of rhTPO use in facilitating mobilization of progenitor cells, but it may promote platelet recovery in the reconstitution phase after high-dose therapy.Trial registration::This trial has been registered in Clinicaltrials.gov as NCT03014102.

Objective:To investigate the relationship between plasma levels of complements before treatment and the clinicopathological feathers and prognoses of diffuse large B-cell lymphoma (DLBCL) patients treated with Rituximab (R)-CHOP or R-CHOP-like therapy.Methods:The clinicopathological data of 105 DLBCL patients treated in cancer Hospital of Chinese Academy of Medical Sciences from 2010 to 2016 were collected. The plasma samples from 105 DLBCL patients treated with R-CHOP or R-CHOP-like therapy and 80 healthy controls were used to detect 34 complement levels before treatment by utilizing antibody microarray. The relationship between plasma levels of complements and the clinicopathological feathers and prognosis of DLBCL patients were analyzed.Results:The signal values of C1QA and CR1L in patients with international prognostic index (IPI) scores of 3-5 were 1 261.43±138.9 and 2 214.69±98.58, respectively, higher than 950.79±80.19 and 984.67±121.79 in patients with IPI scores of 0~2 (both P<0.05). The levels of C1QA and CR1L in the non-complete response (CR) group were 1 165.43±98.56 and 2 263.13±145.63, respectively, higher than 914.70±100.77 and 1 821.34±84.68 in the CR group (both P<0.05). Cox regression analysis showed that elevated C1QA signal value was associated with poor progression-free survival (PFS) and poor overall survival (OS) (PFS: HR=2.063, 95% CI: 1.220-3.489, P=0.007; OS: HR=2.23, 95% CI: 1.036~4.798, P=0.040). After IPI correction by Cox multivariate model, the elevated C1QA signal value was still correlated with poor PFS ( HR=1.765, 95% CI 1.034~3.013, P=0.037). Conclusions:The baseline plasma levels of C1QA and CR1L are correlated with IPI scores and therapeutic effects of DLBCL patients treated with R-CHOP. The baseline plasma level of C1QA has a certain predictive value for the prognostic evaluation of DLBCL.

45.7% of Chinese patients with advanced lung adenocarcinoma were reported to harbour sensitizing epidermal growth factor receptor (EGFR) mutations. Limited therapeutic options are left for non-small cell lung cancer (NSCLC) harbouring sensitizing EGFR mutations after failure of EGFR-tyrosine kinase inhibitor (TKI) therapy and chemotherapy, finding effective options for them is an unmet clinic need. Herein we reported a case that till January 12, 2021, an 82-year-old female with sensitizing EGFR-mutant advanced lung adenocarcinoma received a surprising progression-free survival (PFS) benefit of over 21 months from the combination therapy of pembrolizumab and anlotinib after her failure of treatments of osimertinib, chemotherapy and anlotinib-monotherapy.
