This paper reports a case of a patient with sleep-related painful erections treated by acupuncture combined with abdominal vibration therapy. The main symptom was repeated painful penile erections during nighttime sleep. The syndrome was differentiated as "water failing to nourish wood" and "liver qi stagnation". Acupuncture was applied at Baihui (GV20), Sishencong (EX-HN1), Guanyuan (CV4), and bilateral Neiguan (PC6), Hegu (LI4), Taichong (LR3), Taixi (KI3), Guilai (ST29), Yongquan (KI1), Yanglingquan (GB34), and Sanyinjiao (SP6). The treatment was combined with abdominal vibration therapy. Treatment was given once daily, five times per week. After the first treatment, the severity and duration of nocturnal erection pain were reduced, and sleep quality was improved. After two weeks of treatment, nocturnal erection pain persisted but became tolerable, with significantly shortened duration.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

OBJECTIVE: Salt-processed Psoraleae Fructus (SPF) is widely used as a phytoestrogen-like agent in the treatment of osteoporosis. However, due to improper clinical use or misuse, resulting in liver damage. In this study, network pharmacology was employed to analyze the mechanism of cholestatic liver damage. An adeno-associated virus overexpressing SULT1E1 (rAAV8-SULT1E1) was constructed and the hepatotoxicity of SPF, psoralen, and isopsoralen was determined. METHODS: By utilizing three databases inclding TCMSP, TCMID, and BATMAN- TCM, the targets of the three databases were summarized, and a total of 45 psoralen compounds were included. Network pharmacology analysis was then performed. The adenoviral vectors were injected into the tail vein of C57BL6 mice to elucidate the role of SULT1E1 in SPF-induced cholestasis-mediated hepatotoxicity in vivo. SPF (10 g/kg), psoralen, and isopsoralen (50 mg/kg each) were intragastrically administered to mice for 30 d. B-ultrasound and samples were collected and examined for follow-up experiments. RESULTS: A total of 854 targets were predicted for 45 active components, with 151 cholestasis-mediated hepatotoxicity-related disease targets obtained for SPF. A total of 126 pathways were enriched based on KEGG pathway analysis, with the "estrogen signaling pathway" identified as one of the top 20 pathways. In terms of pathological hepatic changes, treated mice had visually swollen hepatocytes, dilated bile ducts, and elevated serum biochemical markers, which were more prominent in mice treated with isopsoralen than in those treated with other compounds. Notably, the overexpression of SULT1E1 could reverse liver damage in each treatment group. B-ultrasound was used to observe the size of the gallbladder in vivo. The size of the gallbladder was found to significantly increase on day 30 after treatment in the SPF-, psoralen-, and isopsoralen-treated groups, especially the SPF group. Compared with the expression levels in the negative control group (rAAV8-empty + con), the expression levels of FXR, Mrp2, Bsep, SULT1E1, SULT2A1, Ntcp, and Nrf2 decreased, whereas those of CYP7a1 and IL-6 increased in the SPF-, psoralen-, and isopsoralen-treated groups. CONCLUSION The overexpression of SULT1E1 could alleviate the decreased or increased expression of indicators, indicating that SULT1E1 is an important target gene for SPF-induced liver damage. The severity of liver damage was significantly lower in the rAAV8-SULT1E1 groups than in the rAAV8-empty groups.

Objective:To establish an environmental management strategy for the prevention of ventilator-associated pneumonia from the perspective of etiological characteristics and to verify its application effect.Methods:Based on a sampling survey, this study constructed preventive management strategies for ventilator-associated pneumonia by blocking pathogen characteristics from the perspective of both colonization and infection management in patients. From July 2021 to June 2023, a non-synchronous randomized controlled study was conducted, including a control group of 59 cases and an experimental group of 57 cases from ICU of Tianjin Teda Hospital, all of them were mechanically ventilated patients. The effectiveness of the strategy was confirmed.Results:In the control group, there were 35 males and 24 females, with an average age of (46.97 ± 18.84) years. In the experimental group, there were 39 males and 18 females, with an average age of (47.49 ± 13.85) years. During the study period, there were 9 cases of ventilator-associated pneumonia (VAP) in the control group and 2 cases in the experimental group, the difference between the two groups was statistically significant (exact odds ratio=0.031). The duration of mechanical ventilation in the experimental group (122.41 ± 18.36) h, which was shorter than that in the control group (187.62 ± 18.05) h, and the difference was statistically significant ( t=19.28, P<0.05). The length of ICU stay in the experimental group was (8.38 ± 0.79) d, in the control group was (10.99 ± 1.10) d, the difference between them was statistically significant ( t=14.66, P<0.05). On the 7th day, there were 7 cases of positive pathogenic bacteria in sputum culture in the experimental group, which was significantly different from the 29 cases in the control group ( χ2=16.73, P<0.05). Conclusions:The vector management strategy for preventing ventilator-associated pneumonia by blocking etiological characteristics can reduce the incidence of VAP, shorten the duration of mechanical ventilation and ICU stay, and reduce the pathogen load in the sputum of mechanically ventilated patients on the 7th day.

BACKGROUND:Previous studies showed that extracts of Sambucus adnata Wall.have the ability to promote the proliferation and differentiation of osteoblasts,fracture healing,anti-inflammatory and antioxidant effects,which can effectively alleviate the development of osteoarthritis.Vascular endothelial growth factor,on the other hand,is a biomarker for the evaluation of osteoarthritis severity. OBJECTIVE:To investigate the effect and mechanism of two extracts of Sambucus adnata Wall.(methanol extract SAW-ME and dichloromethane extract SAW-DCE)on angiogenesis in osteoarthritis. METHODS:(1)Rat models of osteoarthritis were established using anterior cruciate ligament transection and given SAW-ME and SAW-DCE.A sham group was set as a control.Immunohistochemistry and immunofluorescence were used to detect the changes of articular vascular endothelial growth factor A in joint tissue and vascular endothelial growth factor and"H"type blood vessels in serum of osteoarthritis rats.(2)Vascular endothelial cells EA.hy926 were used as the research object and intervened with SAW-ME and SAW-DCE.Cell proliferation was then detected by MTT assay.Vascular endothelial growth factor was used to induce EA.hy926 cells,and the model of angiogenesis was replicated.Cell scratch assay and tube formation assay were performed to study the role and mechanism.(3)EA.hy926 cells were used for transcriptome sequencing to analyze the characteristic changes of cell differential genes and related functions after SAW-DCE intervention. RESULTS AND CONCLUSION:(1)SAW-ME and SAW-DCE downregulated the expression of vascular endothelial growth factor A in the rat knee cartilage and reduced the formation of"H"type vessels in osteoarthritis rats.SAW-ME could significantly decrease the level of vascular endothelial growth factor in serum of osteoarthritis rats(P<0.05).SAW-DCE could also decrease the level of vascular endothelial growth factor in serum of osteoarthritis rats,but there was no significant change.(2)Both SAW-ME and SAW-DCE significantly inhibited vascular endothelial cell migration and tube formation,and downregulated the expression of Ang1 and Tie2 proteins.(3)Transcriptome sequencing analysis found that abnormal angiogenesis in osteoarthritis was related to the PI3K/AKT signaling pathway.(4)To conclude,SAW-ME and SAW-DCE can inhibit angiogenesis in the rat model of osteoarthritis,and the mechanism may be related to the Ang1/Tie2 and PI3K/AKT signaling pathways.
