Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the Expert Consensus on Blood Flow and Oxygen Delivery Phenotyping and Clinical Management of Septic Shock (2025). The consensus proposes that clinical typing of blood flow-oxygen flow should comprehensively consider cardiac function, vascular tone, oxygen flow utilization status in critical units, and disease trajectory, while optimizing subtype identification by integrating host response phenotypes and artificial intelligence technologies. It advocates establishing a continuous assessment system through multi-site oxygen flow monitoring for organ perfusion, peripheral perfusion monitoring, and critical care ultrasound. Under the framework of the "critical care triangle", the consensus promotes the implementation of individualized, bundled management strategies, providing guidance for multiple management points to restore blood flow-oxygen flow matching, reduce the risk of organ failure, and decrease patient mortality.

Objective:To evaluate the clinical efficacy of multi-disciplinary single center's CCCG-HB-2016 regimen in the treatment of hepatoblastoma (HB) in children.Methods:Clinical data of 36 HB patients treated with CCCG-HB-2016 program from Aug 2016 to March 2020 were analyzed.Results:These 36 patients included 20 boys and 16 girls. The serum AFP was all higher than 2 792 ng/ml,there was a correlation between AFP and tumor risk stratification ( H=14.973, P<0.05). Twenty eight cases (77.78%) were epithelial type and 8 cases (22.22%) were mixed epithelial mesenchymal type.All children were treated by tumor resection combined with chemotherapy, and there was a correlation between tumor risk stratification and surgical resection of liver lobe ( H=8.847, P<0.05). The probability of bone marrow suppression in the low-risk group was 58.33% (35/60),that in the intermediate-risk group was 73.49% (61/83) and in the high-risk group was 80.23% (69/86).All 36 cases were followed up to March 31, 2020,with an average follow-up of 21.9 months and the median survival was 22.5 months.The overall survival rate (OS) and event-free survival rate (EFS) were 97.2% and 83.3% respectively. Conclusions:The multidisciplinary CCCG-HB-2016 regimen was with a high success rate and along with a high incidence of bone marrow suppression.

Fruquintinib is an effective, highly selective and oral VEGFR 1, 2 and 3 tyrosine kinase inhibitor. It was discovered and developed by Hutchison MediPharma for the treatment of solid tumors. In September 2018, fruquintinib received its first global approval in China for use in the treatment of metastatic colorectal cancer (CRC) patients who have failed at least two prior systemic anti-neoplastic therapies. Clinical studies have shown that it has the advantages of low off-target toxicity, good drug resistance and strong curative effect. This article reviews the molecular structure, mechanism of action, pharmacokinetics, clinical efficacy and safety of fruquintinib, as well as its potential clinical applications in other tumor types.

Objective: To explore the blood lead level and its relationship with behavior in school-age children from rural areas of Chongqing. Methods: A total of 697 students from grades 3 to 6 in the fall semester of 2014 from 14 rural townships in one district of Chongqing was selected by using the random cluster sampling method. Blood were sampled to analyze the lead level. Neurobehavioral tests were performed to determine their personal cognitive and memory ability. Questionnaires and physical examinations were administered to obtain the information of confounding factors. All students were divided into Q₁-Q₄ groups according to the quartile of their blood lead level. The relationship between the blood lead level and behavior was analyzed by multivariate logistic regression model and restricted spline regression model. Results: The mean age of 697 students was (10.07±1.36) years old, and the median (interquartile range) of their blood lead level was 44.31 (35.42) μg/L. Multivariate logistic regression model showed that after adjusting for age, gender, body mass index and maternal culture level, compared with Q₁ group, the OR (95%CI) values of high digit symbol substitution test (DSST) scores and high overall memory quotient (MQ) scores in Q₃ group were 1.65 (1.01-2.70) and 2.10 (1.21-3.62), and the OR (95%CI) value of high long term memory (LTM) scores in Q₄ group was 0.53 (0.31-0.92). The results of the restricted spline regression model showed that the dose-response curves between the blood lead level and MQ/LTM test scores were both parabolic (P<0.05). Conclusion The blood lead level of school-age children from rural areas of Chongqing is the same as that from other areas of China, but slightly higher than that from other areas of Chongqing. Children with higher blood lead level have poor long-term memory ability.

Objective To analyze the epidemiological characteristics of malaria in Hechi City,Guangxi Zhuang Autono?mous Region from 2005 to 2015,so as to provide the evidence for formulating and adjusting measures of malaria elimination. Methods The data of malaria cases in 11 counties of Hechi City from 2005 to 2015 were collected and analyzed by using Micro?soft Office Excel 2003 and SPSS 17.0. Results A total of 160 malaria cases were reported in Hechi City from 2005 to 2015, and the annual average malaria incidence was 3.6 per million. There were 10 local recurrence cases(accounting for 6.25%,10/160)and 150 imported cases(accounting for 93.75%,150/160). For the etiology,Plasmodium vivax accounted for 51.87%(83/160)in these cases,P. falciparum accounted for 34.38%(55/160),P. ovale accounted for 1.25%(2/160),P. malariae account?ed for 5.00%(8/160),and the indeterminate accounted for 7.50%(12/160). During the period of 11 years,the malaria inci?dence first dropped and then rose. There were no local cases after 2009. However,an imported falciparum malaria death case was reported in 2010,a severe imported falciparum malaria case was reported in 2013 and another in 2015. A severe case of ma?ternal?neonatal vivax malaria was reported in 2014. These cases were mainly distributed in 10 counties of Hechi City,with more young male adults who engaged in digging mining. More cases concentrated from April to August. Most of the reported malaria cases were imported,60.00%(96/160)of them returned from Africa and Southeast Asia,and 33.75%(54/160)from other do?mestic provinces. The median of the interval from symptom appearance to diagnosis was 5 d,and there was a significant differ?ence among the above years(c2=33.40,P<0.05). Conclusions Malaria is still an important public health problem in Hechi City,and the appropriate control measures and effective tools should be strengthened for malaria elimination. The key to consoli?date the achievements of malaria control is strengthening the malaria monitoring management of the floating population.
