OBJECTIVE: To explore the efficacy and safety of venetoclax combined with demethylating drugs and intense chemotherapy in the treatment of acute myeloid leukemia (AML). METHODS: The clinical data of 76 patients with AML treated in Qilu Hospital of Shandong University Dezhou Hospital from January 2019 to March 2024 were retrospectively analyzed. Patients were divided into observation group and control group. 38 patients in the observation group received venetoclax combined with demethylating drugs (decitabine or azacytidine) and 38 patients in the control group with the "3+7" intensive chemotherapy regimen. The primary endpoints of clinical observation were complete remission (CR), CR with incomplete hematologic recovery (CRi), partial remission (PR), non remission (NR), and overall response rate (ORR). Secondary endpoints were overall survival (OS) and drug safety. RESULTS: After 2 courses of treatment, the CR+CRi rate in observation group and control group was 71.05% and 65.79%, respectively, and the ORR was 81.58% and 78.95%, respectively. After all courses of treatment, CR+CRi rate in the observation group and the control group was 73.68% and 78.95%, respectively, and the ORR was 81.58% and 84.21%, respectively, with no statistical significance between the two groups (P >0.05). After 1 course of treatment, there were statistically significant differences in the proportion and degree of myelosuppression, the duration of neutropenia and the duration of thrombocytopenia between the two groups (P < 0.05), while there were no statistically significant differences in the occurrence of neutropenia with fever between the two groups (P >0.05). The incidence of non-hematological adverse reactions was highest in infection (mainly pulmonary infection) and gastrointestinal reaction. Among the many adverse reactions, there were statistically significant differences in the infection and hypokalemia between the two groups (P < 0.05), the incidence of hypokalemia in observation group and control group was 42.11% and 15.79%, respectively, and the infection rate in observation group and control group was 73.68% and 94.74%, respectively. The median OS was 13.13(1.67-53.63) months in the observation group and 16.60(0.57-59.67) months in the control group. CONCLUSION The combination of venetoclax and demethylating drugs has a low degree of myelosuppression, but a long recovery time, a response rate as good as that of intensive chemotherapy, and a lower infection rate. However, the incidence of hypokalemia is low in the intensive chemotherapy regimen, and the regimen significantly improves the long-term outcome of patients.

The ventral anterior (VA) nucleus of the thalamus is a major target of the basal ganglia and is closely associated with the pathogenesis of Parkinson's disease (PD). Notably, the VA receives direct innervation from the hypothalamic histaminergic system. However, its role in PD remains unknown. Here, we assessed the contribution of histamine to VA neuronal activity and PD motor deficits. Functional magnetic resonance imaging showed reduced VA activity in PD patients. Optogenetic activation of VA neurons or histaminergic afferents significantly alleviated motor deficits in 6-OHDA-induced PD rats. Furthermore, histamine excited VA neurons via H1 and H2 receptors and their coupled hyperpolarization-activated cyclic nucleotide-gated channels, inward-rectifier K⁺ channels, or Ca²⁺-activated K⁺ channels. These results demonstrate that histaminergic afferents actively compensate for Parkinsonian motor deficits by biasing VA activity. These findings suggest that targeting VA histamine receptors and downstream ion channels may be a potential therapeutic strategy for PD motor dysfunction.

Purpose To explore the clinical and imaging characteristics of rupture death cases of pseudoaneurysm,and to enhance the awareness of prevention strategies,early diagnosis and treatment.Materials and Methods Clinical imaging data of six patients with pseudoaneurysm rupture and death in the Second Affiliated Hospital of Air Force Military Medical University from January 2016 to December 2021 were retrospectively analyzed.Results CT and MRI findings of false aneurysms were circular or irregular tumor bodies that protrusion the tumor bearing artery,and could be seen to communicate with the tumor bearing artery.There might be thrombosis in the tumor body,compression displacement of the adjacent tumor bearing artery,thinning or thickening of the lumen.Imaging features of six cases with pseudoaneurysm showed that the location,shape,size,size of rupture,relationship with parent artery and surrounding tissue structure,with clear and definite diagnosis.Two cases of pseudoaneurysm of aortic arch was formed after swallowing date kernel by mistake and removing under endoscope.Pseudoaneurysm formation was caused by trauma in one case,after intervention in one case,and with no clear reason in one case.In one case,pseudoaneurysm of cavernous segment of left internal carotid artery was caused by erosion of adjacent vessel wall by intracranial nonspecific infection.Before death,all 6 cases had sudden symptoms of hematemesis or nosebleed,suggesting pseudoaneurysm rupture.Conclusion The rupture of pseudoaneurysm has a high mortality rate.CT and MR can objectively show the imaging manifestations of pseudoaneurysm,with certain clinical value.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
