Hypertension, a common risk factor for cardiovascular diseases, has aroused global concern. As breakthroughs have been achieved in the traditional Chinese medicine(TCM) and western medicine theories related to the heart and brain, top international journals such as Science pay increasing attention to the functional interaction between the heart and brain in modern medicine, known as the "heart-brain" axis, also referred to as the "cardiovascular-brain" circuit. The heart and brain interact and influence each other through the "heart-brain" axis. Increasing evidence suggests that the inflammation-regulated "heart-brain" axis plays a crucial role in the occurrence and development of hypertension, offering new insights for the treatment of cardiovascular diseases. In TCM, there is a connection between the heart and brain by the sharing of blood essence, interconnected blood vessels, and shared governance over the mind. Diseases of the heart and brain share common pathological and physiological foundations, similar risk factors, and TCM pathogeneses, which form the basis for simultaneous treatment of heart and brain diseases in TCM. The principle of simultaneous treatment of the heart and brain diseases aligns with the theory of "heart-brain" axis. Modern research has found that the heart and brain are the main target organs of hypertension. Long-term high blood pressure can easily cause structural changes, mainly characterized by left ventricular hypertrophy and dilation, leading to hypertensive heart disease. Hypertension can change the structure, blood supply, and function of the brain, being closely related to cerebral atherosclerosis, cerebral infarction, cerebral hemorrhage, cognitive dysfunction, dementia and other brain diseases. TCM treatment of hypertension has a long history. According to the pathogenesis(Yang hyperactivity and blood stasis) of hypertension, the team has developed the core treatment principle of subduing Yang and activating blood. Through extensive clinical exploration and experimental research, the team has developed an effective prescription called Tianxiong Granules. This prescription has shown definite efficacy in stabilizing blood pressure, ameliorating clinical symptoms, and reducing target organ damage. The protective effects of Tianxiong Granules on the heart and brain are reflected in aspects such as symptoms related to the heart and brain, pharmacological effects on ventricular hypertrophy, and brain protection. The preliminary research by the team found that Tianxiong Granules might treat hypertension by inhibiting sympathetic nerve excitation and renin-angiotensin-aldosterone system(RAAS) and targeting mitochondrial autophagy to regulate the activation of the NOD-like receptor family pyrin domain containing 3(NLRP3) inflammasome. The activation of the NLRP3 inflammasome mediates pyroptosis, which is a key mechanism of hypertension. Next, the team will construct the adeno-associated viruses with downregulated NLRP3 expression via adenoviral vectors and use viral tracing technology, left stellate ganglionectomy, and a cardiac denervation model to reveal the mechanism of Tianxiong Granules in regulating the heart-brain interaction in hypertensive rats, from both in vivo and in vitro perspectives. In summary, exploring clinical treatment strategies for hypertension from both heart and brain based on the "heart-brain" axis is likely to be a new direction for the development of drugs for hypertension and offers a new target and basis for intervention in hypertension.

Background: Acute respiratory distress syndrome induced by acute lung injury (ALI) is the main cause for the high mortality of corona-virus disease 2019 (COVID-19). Huashi Baidu formula (HSBD) with the effects of eliminating dampness, clearing heat, ventilating lung, and removing toxin has been proven to be effective in the treatment of COVID-19, especially in severe cases. However, the underlying mechanism and target proteins of HSBD remain unclear. Objective: To provide evidence and decipher the mechanism of HSBD in alleviating inflammation and ALI. Materials and methods: A mouse model of ALI was induced by lipopolysaccharide (LPS), and hematoxylin-eosin staining was used to examine the protective effects of HSBD on the model mice. The cellular thermal shift assay and proteomics analysis were used to predict the target proteins. Furthermore, the A549 cells with peroxiredoxin 5 (PRDX5) knockdown were established to validate the predicted proteins. Results: Huashi Baidu formula treatment mitigated ALI and inflammatory cytokine dysfunction in LPS-induced mice, thus exerting a therapeutic effect on COVID-19. Huashi Baidu formula could serve as a therapeutic agent to alleviate inflammation and lung injury via nuclear factor k B and phosphatidylinositol 3-kinase signaling and interleukin 17 inhibition as well as targeting PRDX5, which could be one of the promising targets for treating inflammation. In the A549 cell line with PRDX5 knockdown (si-PRDX5), the anti-inflammation effects of HSBD, including reversing LPS-induced increase in the nitric oxide level and reduction in the hydrogen peroxide content, were attenuated. Thus, HSBD protected A549 cells from LPS-induced inflammation mainly by targeting PRDX5. Conclusions: Huashi Baidu formula alleviates ALI by targeting nuclear factor κB/phosphatidylinositol 3-kinase and PRDX5, as well as inhibiting the immune response induced by IL-17.

OBJECTIVE: To investigate whether Omicron BA.1 breakthrough infection after receiving the SARS-CoV-2 vaccine could create a strong immunity barrier. METHODS: Blood samples were collected at two different time points from 124 Omicron BA.1 breakthrough infected patients and 124 controls matched for age, gender, and vaccination profile. Live virus-neutralizing antibodies against five SARS-CoV-2 variants, including WT, Gamma, Beta, Delta, and Omicron BA.1, and T-lymphocyte lymphocyte counts in both groups were measured and statistically analyzed. RESULTS: The neutralizing antibody titers against five different variants of SARS-CoV-2 were significantly increased in the vaccinated population infected with the Omicron BA.1 variant at 3 months after infection, but mainly increased the antibody level against the WT strain, and the antibody against the Omicron strain was the lowest. The neutralizing antibody level decreased rapidly 6 months after infection. The T-lymphocyte cell counts of patients with mild and moderate disease recovered at 3 months and completely returned to the normal state at 6 months. CONCLUSION Omicron BA.1 breakthrough infection mainly evoked humoral immune memory in the original strain after vaccination and hardly produced neutralizing antibodies specific to Omicron BA.1. Neutralizing antibodies against the different strains declined rapidly and showed features similar to those of influenza. Thus, T-lymphocytes may play an important role in recovery.

The immunomodulatory effect of Saposhnikoviae Radix polysaccharide(SRP) was evaluated based on the zebrafish mo-del, and its mechanism was explored by transcriptome sequencing and real-time fluorescence-based quantitative PCR(RT-qPCR). The immune-compromised model was induced by navelbine in the immunofluorescence-labeled transgenic zebrafish Tg(lyz: DsRed), and the effect of SRP on the density and distribution of macrophages in zebrafish was evaluated. The effect of SRP on the numbers of macrophages and neutrophils in wild-type AB zebrafish was detected by neutral red and Sudan black B staining. The content of NO in zebrafish was detected by DAF-FM DA fluorescence probe. The content of IL-1β and IL-6 in zebrafish was detected by ELISA. The differentially expressed genes(DEGs) of zebrafish in the blank control group, the model group, and the SRP treatment group were analyzed by transcriptome sequencing. The immune regulation mechanism was analyzed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment, and the expression levels of key genes were verified by RT-qPCR. The results showed that SRP could significantly increase the density of immune cells in zebrafish, increase the number of macrophages and neutrophils, and reduce the content of NO, IL-1β, and IL-6 in immune-compromised zebrafish. The results of transcriptome sequencing analysis showed that SRP could affect the expression level of immune-related genes on Toll-like receptor pathway and herpes simplex infection pathway to affect the release of downstream cytokines and interferon, thereby completing the activation process of T cells and playing a role in regulating the immune activity of the body.

Immunoglobulin (IgG) glycosylation affects the effector functions of IgG in a myriad of biological processes and has been closely associated with numerous autoimmune diseases, including systemic lupus erythematosus (SLE), thus underlining the pathogenic role of glycosylation aberration in autoimmunity. This study aims to explore the relationship between IgG sialylation patterns and lupus pregnancy. Relative to that in serum samples from the control cohort, IgG sialylation level was aberrantly downregulated in serum samples from the SLE cohort at four stages (from preconception to the third trimester of pregnancy) and was significantly associated with lupus activity and fetal loss during lupus pregnancy. The type I interferon signature of pregnant patients with SLE was negatively correlated with the level of IgG sialylation. The lack of sialylation dampened the ability of IgG to suppress the functions of plasmacytoid dendritic cells (pDCs). RNA-seq analysis further revealed that the expression of genes associated with the spleen tyrosine kinase (SYK) signaling pathway significantly differed between IgG- and deSia-IgG-treated pDCs. This finding was confirmed by the attenuation of the ability to phosphorylate SYK and BLNK in deSia-IgG. Finally, the coculture of pDCs isolated from pregnant patients with SLE with IgG/deSia-IgG demonstrated the sialylation-dependent anti-inflammatory function of IgG. Our findings suggested that IgG influences lupus activity through regulating pDCs function via the modulation of the SYK pathway in a sialic acid-dependent manner.

OBJECTIVE: To investigate the effect of celastrol on the proliferation and apoptosis of human multiple myeloma (MM) cell lines, reveal the relationship between IRAK4/ERK/p38 signaling pathway and celastrol regulating the proliferation and apoptosis of H929 and ARP-1 cells, and explore whether celastrol combined with bortezomib has synergistic effect. METHODS: CCK-8 method was used to detect the viability of MM cell lines H929 and ARP-1 treated by different concentrations of celastrol, bortezomib, and their combination, and the synergistic effect was determined by Kim's formula. The apoptosis rate of H929 cells and necrosis rate of ARP-1 were detected by Annexin V/PI method. The expression of key proteins and apoptosis proteins in IRAK4/ERK/p38 signaling pathway were detected by Western blot. RESULTS: Celastrol could significantly inhibit the proliferation of H929 and ARP-1 cells (r=0.9018, r=0.9244) and induce apoptosis in a time-dependent manner. Compared with the control group, celastrol could significantly up-regulate the expression of PARP and cleaved caspase-3 while down-regulate the expression of p-IRAK4, p-ERK, and p-p38 in H929 and ARP-1 cells. Celastrol and bortezomib alone inhibited the proliferation of H929 and ARP-1 cells. Compared with celastrol and bortezomib alone, their combination had lower cell survival rate and higher apoptosis rate (P<0.05). CONCLUSION Celastrol can inhibit the proliferation and promote the apoptosis of H929 and ARP-1 cells, which may be related to inhibiting the phosphorylation of IRAK4 and blocking the activation of IRAK4/ERK/p38 signaling pathway. Celastrol combined with bortezomib has synergistic effect, which can more effectively inhibit the proliferation and induce apoptosis of H929 and ARP-1 cells.

BACKGROUND: Colorectal cancer (CRC) is the fourth cause of cancer death in China. We aimed to provide national and subnational estimates and changes of CRC premature mortality burden during 2005-2020. METHODS: Data from multi-source on the basis of the national surveillance mortality system were used to estimate mortality and years of life lost (YLL) of CRC in the Chinese population during 2005-2020. Estimates were generated and compared for 31 provincial-level administrative divisions in China. RESULTS: Estimated CRC deaths increased from 111.41 thousand in 2005 to 178.02 thousand in 2020; age-standardized mortality rate decreased from 10.01 per 100,000 in 2005 to 9.68 per 100,000 in 2020. Substantial reduction in CRC premature mortality burden, as measured by age-standardized YLL rate, was observed with a reduction of 10.20% nationwide. Marked differences were observed in the geographical patterns of provincial units, and they appeared to be obvious in areas with higher economic development. Population aging was the dominant driver which contributed to the increase in CRC deaths, followed by population growth and age-specific mortality change. CONCLUSIONS Substantial discrepancies were observed in the premature mortality burden of CRC across China. Targeted considerations were needed to promote a healthy lifestyle, expand cost-effective CRC early screening and diagnosis, and improve medical treatment to reduce CRC mortality among high-risk populations and regions with inadequate healthcare resources.
