Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Immune checkpoint inhibitor(ICI)associated diabetes mellitus(DM)a rare specific type of diabetes,usually developed after the treatment of programmed cell death protein 1(PD-1)inhibitor or programmed cell death ligand 1(PD-L1)inhibitor.We reported 4 cases of DM after ICI use.These patients had a subacute onset,6 to 17 months after the first use of the drug,with diabetic autoantibodies negative.Pancreas atrophy was observed in one of them.All of the patients received treatment of insulin.

Leber's hereditary optic neuropathy (LHON) is an ocular mitochondrial disease that involves the impairment of mitochondrial complex I, which is an important contributor to blindness among young adults across the globe. However, the disorder has no available cures, since the approved drug idebenone for LHON in Europe relies on bypassing complex I defects rather than fixing them. Herein, PARKIN mRNA-loaded nanoparticle (mNP)-engineered mitochondria (mNP-Mito) were designed to replace dysfunctional mitochondria with the delivery of exogenous mitochondria, normalizing the function of complex I for treating LHON. The mNP-Mito facilitated the supplementation of healthy mitochondria containing functional complex I via mitochondrial transfer, along with the elimination of dysfunctional mitochondria with impaired complex I via an enhanced PARKIN-mediated mitophagy process. In a mouse model induced with a complex I inhibitor (rotenone, Rot), mNP-Mito enhanced the presence of healthy mitochondria and exhibited a sharp increase in complex I activity (76.5%) compared to the group exposed to Rot damage (29.5%), which greatly promoted the restoration of ATP generation and mitigation of ocular mitochondrial disease-related phenotypes. This study highlights the significance of nanoengineered mitochondria as a promising and feasible tool for the replacement of dysfunctional mitochondria and the repair of mitochondrial function in mitochondrial disease therapies.

Placental implantation disorders (PAS) have become the main cause of postpartum hemorrhage and perinatal hysterectomy. The risk of placental implantation surgery is high. It is important to conduct screening and diagnosis of high-risk patients with PAS, promptly refer patients with severe PAS, choose appropriate surgical opportunities, form a multidisciplinary team, conduct reliable preoperative evaluation and sufficient preoperative preparation, develop reasonable surgical plans and rescue plans, and have experienced doctors perform the surgery to minimize the risk. Standardized management of clinical diagnosis and treatment for patients will help improve pregnancy outcomes, reduce hysterectomy rates, and reduce severe complications and mortality rates in pregnant and postpartum women.

Objective: Analysis of the effect of triggering receptor-1 expressed on myeloid cells (TREM-1) in nonalcoholic fatty liver disease (NAFLD) and the mechanism. Methods: The oleic acid-treated HepG2 cells were divided into model group, overexpression group, interference group A, interference group B and negative control group. The mouse model of NAFLD was generated and randomly divided into (nuclear factor-κB) NF-κB inhibition group, protein kinase B (AKT) inhibition group, knockout group A, knockout group B and control group. The expression of inflammatory factors and TREM-1 in liver tissue was detected by PCR, and fat accumulation was detected by oil red O staining. Western blotting was used to detect the expression of TREM-1 and signaling pathway proteins, and HE staining was used to detect liver tissue changes. Results: TREM-1 was up-regulated in liver tissue of NAFLD mice [(0.936±0.127) vs. (0.432±0.105)] and in oleic acid-treated HepG2 cells. In oleic acid-treated HepG2 cells, overexpression of TREM-1 increased inflammatory factor expression and increased lipid droplets; inhibition of TREM-1 expression decreased inflammatory factor expression, and lipid droplets decreased. Knockout of TREM-1 and inhibition of NF-κB in NAFLD mice reduced hepatocyte inflammatory factor expression and reduced liver damage; knockout of TREM-1 and inhibition of AKT reduced liver tissue lipids and drops accumulate. Conclusions The overexpression of TREM-1 in NAFLD mice liver tissue can regulate inflammatory factor expression and lipid droplets through NF-κB and AKT signal pathway. TREM-1 might be a potential therapeutic target of NAFLD.

With the increasing incidence of osteoporosis, osteoporotic vertebral compression fracture (OVCF) has become a common disease in the elderly. Relevant researches have indicated that percutaneous vertebroplasty (PVP) has become the main treatment for painful osteoporotic vertebral compression fractures. In aspect of perioperative nursing care for PVP, both domestic and foreign scholars have published a large number of research reports, indicating that perioperative nursing intervention can alleviate the pain, reduce the incidence of complications, improve the quality of life of patients, and promote rehabilitation. This article aims to make a comprehensive review about the perioperative nursing care for patients with osteoporotic vertebral compression fractures who are receiving PVP so as to provide reference for clinical nursing staff in the implementation of nursing intervention.

Objective:To evaluate the feasibility and therapeutic efficacy of transhepatic arterial embolization with superparamagnetic iron oxide (SPIO) and lipiodol (LIP) for the treatment of VX2 tumor in rabbits.Methods:Twenty-four rabbits with hepatic VX2 tumors by surgical implantation were randomly divided into 4 groups and treated with transhepatic arterial embolization of 4 different agents as follows (n=6 each):doxorubicin (DOX) group,DOX-LIP group,SPIO-DOX group,and SPIO-DOX-LIP group.Liver function (AST and ALT) was measured at 0,1,3,5 and 7 d after transhepatic arterial embolization.The serum DOX level was measured at 0,5,15,30,60,and 120 minutes after transhepatic arterial embolization.MRI was performed at 7 d after the treatment to assess the distribution of SPIO in the SPIO-DOX group and SPIO-DOX-LIP group,while CT was performed to assess the distribution of LIP in the DOX-LIP group and SPIO-DOX-LIP group.All the rabbits were sacrificed and their livers were removed at 7 d after treatment for the detection of tissue DOX level.The histopathologic examinations were performed including HE staining,Prussian blue staining and TUNEL assay,and then the tumor necrosis percentage and apoptosis index were calculated.Results:Compared to the DOX group,the levels of AST and ALT in other 3 groups were significantly elevated at 1 and 3 d after embolization (P＜0.05).The levels of ALT and AST in the DOX group,DOX-LIP group or SPIO-DOX-LIP group returned to the baseline at day 7,there were no significant differences (P＞0.05).The SPIO-DOX-LIP group exhibited the lowest serum DOX level at all time points up to 120 minutes after embolization (P＜0.05).However,the tissue DOX level in the SPIO-DOX-LIP group was the highest among all groups at day 7 (P＜0.05).The SPIO-DOX group and SPIO-DOX-LIP group showed significantly lower MRI signal intensity of tumors in T2 weighted imaging (T2WI) at day 7.Meanwhile DOX-LIP group and SPIO-DOX-LIP group showed that high-density lipiodol was deposited in the tumors in CT images.Histopathologic findings showed an almost complete central necrosis coagulation of tumors in the SPIO-DOX-LIP group,and the tumor necrosis percentage and tumor apoptosis index were significantly increased in the SPIO-DOX-LIP group compared to those in other 3 groups (P＜0.05).Conclusion:This novel drug-delivery system of SPIO nano-drug carrier together with LIP is safe and feasible when it is used for transhepatic arterial embolization for liver tumor.It provides an excellent MR and CT visualization and improves the therapeutic efficacy for the treatment of rabbit VX2 liver tumor.

Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10⁹/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10⁹/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10⁹/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10⁹/L) at 4^th week, 8^th week and 12^th week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10⁹/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.
