To summarise the clinical experience of treating insomnia with the method of resolving depression， regulating the middle， and tranquilising mind. It is believed that the key to the pathogenesis of insomnia lies in qi depression， disharmony of qi pivot， and disharmony of qi and blood， and the core treatment is to resolve depression， regulating the middle， and tranquilising mind. The self-prescribed Jieyu Anmian Formula （解郁安眠方） could be used as the basic treatment， then modified according to the performance of the patient and syndromes. For syndrome of liver depression restricting spleen， the treatment should soothe liver and invigorate spleen， resolve depression and regulate the middle； for syndrome of liver depression and phlegm coagulation， the treatment should resolve depression and phlegm， support the earth and free the wood； for syndrome of liver depression transforming into fire， the treatment should soothe liver and clear fire， resolve depression and dysphoria； for syndrome of qi stagnation and blood stasis， the treatment should activate blood and regulate the middle， resolve depression and tranquilise mind.

Background Atherosclerotic cardiovascular disease (ASCVD) is a major contributor to the global burden of cardiovascular diseases. However, evidence from meta-analyses on the association between ambient ozone exposure and ASCVD risk remains relatively insufficient. Objective To explore the epidemiological association between ambient ozone exposure and ASCVD, providing scientific evidence for ASCVD prevention and control from the perspective of environmental risk factor management. Methods We systematically searched PubMed, Web of Science, Embase, the Cochrane Library, CNKI, Wanfang Database, CBM, and VIP for published epidemiological studies on the relationship between ambient ozone exposure and ASCVD from January 2007 to December 2023. We performed quality assessment and data extraction of the included studies, and utilized meta-analysis to evaluate the effects of short-term and long-term ozone exposure on different ASCVD outcomes, including mortality and incidence of ischemic heart disease (IHD) and ischemic stroke (IS). Results A total of 24 studies were included based on a set of predetermined eligibility criteria. The meta-analysis results indicated that short-term ozone exposure was associated with an increased risk of ASCVD mortality and incidence. Specifically, short-term ozone exposure was significantly associated with an elevated risk of IHD mortality (combined RR=1.011, 95%CI: 1.008, 1.015; P < 0.05). Additionally, short-term ozone exposure was significantly linked to increased IS mortality (combined RR=1.005, 95%CI: 1.003, 1.008; P < 0.05) and incidence (combined RR=1.015, 95%CI: 1.003, 1.027; P < 0.05). Conclusion Short-term exposure to ambient ozone significantly elevates acute cardiovascular disease risk. However, the epidemiological association between long-term ozone exposure and ASCVD remains inconclusive. Future high-quality cohort studies with refined exposure assessment methods are warranted to elucidate the chronic cardiovascular effects of ozone exposure.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

OBJECTIVES: We present a new low-dose CT reconstruction method using sub-pixel and anisotropic diffusion. METHODS: The sub-pixel intensity values and their second-order differences were obtained using linear interpolation techniques, and the new gradient information was then embedded into an anisotropic diffusion process, which was introduced into a penalty-weighted least squares model to reduce the noise in low-dose CT projection data. The high-quality CT image was finally reconstructed using the classical filtered back-projection (FBP) algorithm from the estimated data. RESULTS: In the Shepp-Logan phantom experiments, the structural similarity (SSIM) index of the CT image reconstructed by the proposed algorithm, as compared with FBP, PWLS-Gibbs and PWLS-TV algorithms, was increased by 28.13%, 5.49%, and 0.91%, the feature similarity (FSIM) index was increased by 21.08%, 1.78%, and 1.36%, and the root mean square error (RMSE) was reduced by 69.59%, 18.96%, and 3.90%, respectively. In the digital XCAT phantom experiments, the SSIM index of the CT image reconstructed by the proposed algorithm, as compared with FBP, PWLS-Gibbs and PWLS-TV algorithms, was increased by 14.24%, 1.43% and 7.89%, the FSIM index was increased by 9.61%, 1.78% and 5.66%, and the RMSE was reduced by 26.88%, 9.41% and 18.39%, respectively. In clinical experiments, the SSIM index of the image reconstructed using the proposed algorithm was increased by 19.24%, 15.63% and 3.68%, the FSIM index was increased by 4.30%, 2.92% and 0.43%, and the RMSE was reduced by 44.60%, 36.84% and 15.22% in comparison with FBP, PWLS-Gibbs and PWLS-TV algorithms, respectively. CONCLUSIONS The proposed method can effectively reduce the noises and artifacts while maintaining the structural details in low-dose CT images.

OBJECTIVES: To explore the mechanism of Circ-MYOCD back-splicing and its regulatory role in myocardial hypertrophy. METHODS: Sanger sequencing and RNase R assays were performed to verify the circularity and stability of Circ-MYOCD, whose subcellular distribution was determined by nuclear-cytoplasmic fractionation. Bioinformatics analysis and mass spectrometry from pull-down assays were conducted to predict the RNA-binding proteins (RBPs) interacting with Circ-MYOCD. In rat cardiomyocytes H9C2 cells, the effects of HNRNPH1 and HNRNPL knockdown and overexpression on Circ-MYOCD back-splicing were evaluated. In a H9C2 cell model of angiotensin II (Ang II)-induced myocardial hypertrophy, the expression of HNRNPH1 was detected, the effects of HNRNPH1 knockdown and overexpression on progression of myocardial hypertrophy were assessed, and the regulatory effect of HNRNPH1 on Circ-MYOCD back-splicing was analyzed. RESULTS: Sanger sequencing confirmed that the junction primers could amplify the correct Circ-MYOCD sequence. RNase R and nuclear-cytoplasmic fractionation assays showed that Circ-MYOCD was stable and predominantly localized in the cytoplasm. Bioinformatics analysis and mass spectrometry from the Circ-MYOCD pull-down assay identified HNRNPH1 and HNRNPL as the RBPs interacting with Circ-MYOCD. In H9C2 cells, HNRNPH1 knockdown significantly enhanced while its overexpression inhibited Circ-MYOCD back-splicing; HNRNPH1 overexpression obviously increased the expressions of myocardial hypertrophy markers ANP and BNP, while its knockdown produced the opposite effect. In Ang II-induced H9C2 cells, which exhibited a significant increase of HNRNPH1 expression and increased expressions of ANP and BNP, HNRNPH1 knockdown obviously increased Circ-MYOCD expression, decreased MYOCD expression and lowered both ANP and BNP expressions. CONCLUSIONS HNRNPH1 regulates Circ-MYOCD back-splicing to influence the progression of myocardial hypertrophy.
