Coronary heart disease （CHD） has a distinct circadian rhythmicity in its onset， which is closely related to the waxing and waning of qi and blood in the channel passages of the human body. Grounded in the circadian rhythm theory of "correspondence between heaven and humankind"， this paper explores the pathogenic evolution rules of qi-blood disharmony， channel obstruction， interacting as cause and effect with circadian rhythm disorders in CHD. Clinically， CHD can be observed to attack in the early morning， at night， in the afternoon， and at fixed or unfixed circadian intervals. The pathogenesis rhythms at different time nodes can correspondingly reflect the susceptibility tendencies and pathological stress responses of the human body to core pathogeneses such as yang deficiency with cold congelation， yin deficiency with yang floating， qi and yin deficiency， and liver constraint with qi stagnation under specific temporal states. Treatment should be adapted to the season and time， regulating yin and yang in accordance with biological rhythms. It is recommended to regulate qi during the daytime by promoting ascending and dispersing to unblock the channel passages， and select the appropriate timing for administration to harness natural timing. At the Mao （卯） hour， yang ascends while yin descends， and taking medication at this time conforms to the ascending of yang qi. At the Wu （午） hour， the heart meridian is active， and taking medication at this time warms the channel passages and assists heart yang， which can be treated with modified Buzhong Yiqi Decoction （补中益气汤） or Shengyang Yiwei Decoction （升阳益胃汤）. At night， blood should be harmonized， when the channel passages are unblocked through nourishing， restraining， and searching， with Lianmei Decoction （连梅汤） combined with Dahuang Zhechong Pill （大黄䗪虫丸）. Following the temporal rhythm， the focus is put on the transitional time of day and night and the four seasons to treat disease before it arises， resonating and corresponding with the natural rhythm.

Objective:To analyze the effects of Mulligan technique combined with isokinetic exercise training (IET) on isokinetic muscle strength and neuromuscular control ability in patients with knee osteoarthritis (KOA).Methods:A retrospective case-control study was conducted. A total of 49 patients with KOA who underwent IET at Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to January 2022 were included in the control group. An additional 49 patients with KOA who received Mulligan technique and IET at the same hospital from June 2022 to June 2023 were included in the observation group. Both groups were treated for 8 successive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Lysholm score, proprioception metrics [including average track error (ATE) and test time execution (TTE)], isokinetic muscle strength [peak torque (PT) and average power (AP) for flexors and extensors at 60°/s, 90°/s, and 120°/s)]were compared between the two groups before and after 4 and 8 weeks of intervention. Additionally, Visual Analog Scale score was compared between the two groups at baseline and after 8 weeks of intervention.Results:There was no statistically significant difference in WOMAC score, Lysholm score, or PT and AP levels for flexor and extensor muscles at 60°/s, 120°/s, and 180°/s between the two groups before intervention (all P > 0.05). After 4 and 8 weeks of intervention, the levels of PT and AP for both flexors and extensors at 60°/s, 120°/s, and 180°/s, as well as the Lysholm scores, were significantly higher in the observation group compared with the control group [PT level: t = -0.10, -3.03, -3.85, -0.35, -3.62, -3.95, -0.27, -5.51, -6.52, -1.13, -2.74, -3.68, -0.09, -2.91, -5.79, -0.13, -4.66, -6.05; AP level: t = -0.23, -4.77, -6.15, 0.01, -3.10, -3.75, -0.13, -3.73, -3.44, 0.16, -2.09, -4.05, -0.17, -3.71, -3.51, -0.27, -3.26, -3.69; Lysholm score: t = -7.17, -6.44; all P < 0.05]. After 4 and 8 weeks of intervention, the WOMAC score, ATE, and TTE in the observation group were significantly lower than those in the control group [WOMAC score: t = 3.68, 0.64; ATE level: t = 3.88, 4.13; TTE level: t = 4.86, 4.60; all P < 0.05]. After 8 weeks of intervention, both groups had lower Visual Analog Scale scores compared with their scores before the intervention (U control group = -8.75, U observation group = -8.63), with the observation group showing significantly lower scores than the control group ( U = -5.95, P < 0.001). Conclusions:The Mulligan technique combined with IET can effectively alleviate knee joint pain in patients with KOA, promote the recovery of knee joint function, enhance proprioceptive recovery, and improve neuromuscular control abilities.

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.

Objective:To analyze the relationship between genotype and clinical phenotype of the MYH7-R453C mutation in five Chinese hypertrophic cardiomyopathy (HCM) families.Methods:A retrospective cohort study was conducted on 527 unrelated HCM probands who were first diagnosed at the First Affiliated Hospital of Air Force Medical University (Xijing Hospital) from February 2014 to July 2018, and the high-throughput whole exome targeted sequencing of 96 genes related to hereditary cardiovascular disease was performed on the probands. The probands carrying the MYH7-R453C mutation were screened out, and their family members carrying the mutation were verified using Sanger sequencing. Healthy individuals without family history of genetic diseases from the same period and ethnicity were recruited as controls. Clinical data such as echocardiography, 12-lead electrocardiogram, and cardiac magnetic resonance imaging of the probands and their family members were collected, and the correlation between patient genotype and clinical phenotype was analyzed. Endpoint or key events were recorded through hospital re-examination or telephone follow-up.Results:The MYH7-R453C mutation was detected in 5 HCM probands, and clinical data and genetic results of 20 family members, including probands, were collected. Among them, 13 carried the MYH7-R453C mutation, of which 12 were diagnosed with HCM, and one child (F1Ⅲ 5) experienced early changes of HCM. The seven family members who did not carry the MYH7-R453C mutation had normal echocardiograms and 12-lead electrocardiograms. Among the 12 patients diagnosed with HCM, 2 experienced (F2Ⅱ 7, F5Ⅰ 2) sudden cardiac death, 2 experienced (F1Ⅲ 1, F3Ⅲ 3) events of sudden cardiac death survival, 2(F1Ⅱ 2, F3Ⅱ 1) died from heart failure during the follow-up period. Combined with the initial visit and follow-up, 4 families (F1, F2, F3, F5) had a family history of sudden death, among which 3 families probands or multiple family members experiencing sudden death before the age of 30 and adverse outcomes such as implantation of implantable cardioverter-defibrillators after sudden death survival. Conclusions:In the five families with HCM carrying MYH7-R453C mutations, genotype is highly correlated with clinical phenotype, and patients have a high risk of sudden death and poor prognosis. Early diagnosis of individuals carrying the MYH7-R453C gene mutation, both within the patient′s family and in the patients themselves, is crucial for initiating early treatment, preventing sudden death, and assessing prognosis.

OBJECTIVE: To explore the prenatal and postnatal features and genetic characteristics of patients with Lymphedema-Distichiasis syndrome (LDS) due to variants of FOXC2 gene. METHODS: A retrospective analysis was carried out on the phenotypic information, fetal ultrasound image, and genetic testing of two Chinese pedigrees diagnosed at the Third Affiliated Hospital of Zhengzhou University. A literature review was also carried out by searching the China National Knowledge Infrastructure (CNKI), Wanfang Database, and PubMed databases dated from January 2010 to June 2024 using keywords "Lymphedema-Distichiasis syndrome " and "FOXC2 ". This study has been approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethic No. 2021-046-01). RESULTS: Neither family was found to harbor chromosomal aneuploidy or pathogenic CNVs larger than 100 kb. The fetuses from pedigree 1 and pedigree 2 were respectively found to be heterozygous for a c.361C>T (p.R121C) variant and a c.168C>A (p.Y56*) variant of the FOXC2 gene. Both variants were paternally derived. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variants were classified as pathogenic and likely pathogenic, respectively. Literature search has identified 20 articles, and combined with our cases, a total of 117 patients were identified. Among them, 13 had shown prenatal phenotypes, primarily with increased nuchal translucency (NT) (12/13), urinary abnormalities (5/12), and fetal edema (4/13). Postnatal phenotypes were observed in 110 cases, mainly as distichiasis (87/110) and lymphedema (73/110). Only 6 cases had both prenatal and postnatal phenotypes. A total of 32 genetic variants were identified. CONCLUSION The primary prenatal manifestations of LDS include increased NT, fetal edema, pleural and abdominal effusion, and separation of renal collecting system. Postnatal phenotypes are primarily characterized by lymphedema, distichiasis, and spinal extradural arachnoid cysts. Discovery of the c.168C>A variant has expanded the spectrum of FOXC2 gene mutations in China.

The typical hallmark of tumor evolution is metabolic dysregulation. In addition to secreting immunoregulatory metabolites, tumor cells and various immune cells display different metabolic pathways and plasticity. Harnessing the metabolic differences to reduce the tumor and immunosuppressive cells while enhancing the activity of positive immunoregulatory cells is a promising strategy. We develop a nanoplatform (CLCeMOF) based on cerium metal-organic framework (CeMOF) by lactate oxidase (LOX) modification and glutaminase inhibitor (CB839) loading. The cascade catalytic reactions induced by CLCeMOF generate reactive oxygen species "storm" to elicit immune responses. Meanwhile, LOX-mediated metabolite lactate exhaustion relieves the immunosuppressive tumor microenvironment, preparing the ground for intracellular regulation. Most noticeably, the immunometabolic checkpoint blockade therapy, as a result of glutamine antagonism, is exploited for overall cell mobilization. It is found that CLCeMOF inhibited glutamine metabolism-dependent cells (tumor cells, immunosuppressive cells, etc.), increased infiltration of dendritic cells, and especially reprogrammed CD8⁺ T lymphocytes with considerable metabolic flexibility toward a highly activated, long-lived, and memory-like phenotype. Such an idea intervenes both metabolite (lactate) and cellular metabolic pathway, which essentially alters overall cell fates toward the desired situation. Collectively, the metabolic intervention strategy is bound to break the evolutionary adaptability of tumors for reinforced immunotherapy.
