Patients requiring extracorporeal membrane oxygenation (ECMO) often need concurrent continuous renal replacement therapy (CRRT). At present, there are various connection methods between ECMO and CRRT circuits, among which in-series integration is the most common. However, ECMO blood flow and catheter type, pressure changes at the pre-pump, post-pump pre-oxygenator, and post-oxygenator segments frequently result in circuit pressures that exceed the alarm threshold of the device. Excessive negative or positive pressures may compromise blood withdrawal and return within the CRRT circuit, leading to frequent system alarms, interruptions in therapy, filter occlusion, and an increased risk of thrombus formation. To address this issue, the critical care nursing team of Zhongda Hospital Affiliated to Southeast University, developed a novel pressure-regulating clamp for CRRT vascular access in ECMO patient, which has been granted a National Utility Model Patent of China (patent number: ZL 2021 2 1496610.7). The device comprises opposing left and right clamp arms joined at the top by a flexible plastic bridge, with dual internal compression surfaces designed to fit CRRT tubing of various calibers. A locking mechanism and serrated strip at the base enable precise adjustment of the compression distance, thereby modulating the tubing's cross-sectional area. This configuration allows real-time regulation of blood flow and stabilization of pressures at blood withdrawal and return sites within the CRRT circuit. By reducing pressure-related alarms and extending filter life, the device may enhance the safety and efficiency of CRRT delivery during ECMO. It is user-friendly, cost-effective, and well-suited for broad clinical implementation, with the potential to alleviate the overall treatment burden on patients and their families.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.

Extranodal NK/T-cell lymphoma (ENKTCL) is a relatively rare group of highly aggressive non-Hodgkin′s lymphoma (NHL). The disease has rapid clinical progress, high degree of malignancy and poor prognosis. Traditional chemoradiotherapy regimens have not shown good efficacy. In recent years, the immunotherapy of tumors has developed rapidly. At present, it has shown strong therapeutic activity in the treatment of various solid tumors such as non-small cell lung cancer, prostate cancer, melanoma and kidney cancer. Multiple tumor immunotherapy drugs have been approved by the US Food and Drug Administration (FDA) for clinical use. This article reviews recent novel immunotherapeutic regimens of ENKTCL, hoping to change the treatment modality of this malignant disease.

In the current study, we aim to investigate whether post-traumatic stress disorder (PTSD) is associated with structural alterations in specific subfields of hippocampus comparing with trauma-exposed control (TC) in a relatively large sample. We included 67 PTSD patients who were diagnosed under Diagnostic and Statistical Manual of Mental Disorders (4th Edition) (DSM-Ⅳ) criteria and 78 age- and sex-matched non-PTSD adult survivors who experienced similar stressors. High resolution T1 weighted images were obtained via a GE 3.0 T scanner. The structural data was automatically segmented using FreeSurfer software, and volume of whole hippocampus and subfield including CA1, CA2-3, CA4-DG, fimbria, presubiculum, subiculum and fissure were extracted. Volume differences between the two groups were statistically compared with age, years of education, duration from the events and intracranial volume (ICV) as covariates. Hemisphere, sex and diagnosis were entered as fixed factors. Relationship between morphometric measurements with Clinician-Administered PTSD Scale (CAPS) score and illness duration were performed using Pearson's correlation with SPSS. Comparing to TC, PTSD patients showed no statistically significant alteration in volumes of the whole hippocampus and all the subfields ( > 0.05). In male patients, there were significant correlations between CAPS score and volume of right CA2-3 ( = 0.197, = 0.034), right subiculum ( = 0.245, = 0.016), and duration statistically correlated with right fissure ( = 0.247, = 0.016). In female patients, CAPS scores significant correlated with volume of left presubiculum ( = 0.095, = 0.042), left subiculum ( = 0.090, = 0.048), and left CA4-DG ( = 0.099, = 0.037). The main findings of the current study suggest that stress event causes non-selective damage to hippocampus in both PTSD patients and TC, and gender-specific lateralization may underlie PTSD pathology.
