The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated, becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist (GLP1-RA) and sodium glucose cotransporter-2 inhibitors (SGLT2) are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports, this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases (e.g., hyperglycemia, insulin resistance, and inflammation), related targets such as apolipoprotein C-Ⅲ (APOC3), S100 calcium-binding protein A8/A9 (S100A8/A9), growth/differentiation factor-15 (GDF-15), and NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), advanced glycation end products, insulin resistance, endothelial dysfunction, endoplasmic reticulum stress, mitochondrial dysfunction, and intestinal flora disorder. In addition, this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients (e.g., baicalein, puerarin, curcumin, notoginsenoside, and tanshinone ⅡA), single herbal medicines (e.g., Astragali Radix, Ginseng Radix et Rhizoma, Sophorae Flavescentis Radix, Cinnamomi Cortex, and Corni Fructus), and compound formulas (e.g., Buzang Tongluo Fang, Yiqi Yangyin Huoxue Fang, Shenqi Fang, Huangqisan, Danggui Buxue Tang, and Liuwei Dihuang Wan) of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress, ameliorating dyslipidemia and insulin resistance, protecting islet β cell function, repairing endothelial damage, inhibiting smooth muscle cell proliferation, foam cell formation, macrophage polarization, and cardiac hypertrophy and fibrosis, and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B (IRS/PI3K/Akt), peroxisome proliferator-activated receptor α/γ (PPAR α/γ), nuclear factor-kappa B (NF-κB), adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), hypoxia-inducible factor-1-BCH domain-containing protein (HIF-1-BNIP), vascular endothelial growth factor/hypoxia-inducible factor-1α (VEGF/HIF-1α) and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.

Clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR associated nuclease 9 (CRISPR/Cas9) is a self-defense system found in bacteria and archaea that enables targeted gene editing based on the principle. Due to its universality, efficiency, and simplicity, CRISPR/Cas9 has been applied in the pathological mechanism and prevention and treatment of diseases in many fields. Cerebrovascular diseases and central nervous system diseases seriously endanger human health. Stroke is related to genetics, unhealthy living habits, chronic diseases, and other factors. The brain tissue structure is complex and the cell types are diverse. It is difficult for a universal gene editing platform to study target genes safely, specifically, and efficiently. Scholars have continuously improved and optimized gene editing technology, explored the potential and research methods of gene editing technology, and promoted the research process of brain science. After a brief introduction to the mechanism of CRISPR/Cas9, this paper mainly summarized the optimization of the system in the fields of cerebral science including delivery methods, adeno-associated virus assembly, and new nanomaterials. Its application in cerebrovascular research including vascular homeostasis, microglial homeostasis, angiogenesis, blood-brain barrier, and drug screening was also summarized. Finally, this paper prospected the development of CRISPR/Cas9 in traditional Chinese medicine, hoping to provide references for related research design.

The theory of "liver opens at the eyes" was first seen in Yellow Emperor's Internal Canon of Medicine, which is the ancient people's summary of the connection between the liver and the eyes. The theory of "liver opens at the eyes" suggests the characteristic of "co-damage and co-recover of liver and eyes". It has been found in clinical practice that liver diseases and eye diseases often occur together, and "liver and eyes co-recover" is an ideal choice. The key to achieving "liver and eyes co-recover" is to analyze its pharmacological material basis and mechanism. With the development of modern medicine, more and more evidence indicates that the liver and eyes have complex and close relationships in physiological and pathological aspects. In a pathological state, there is a phenomenon of "liver and eyes co-damage", and after the intervention of traditional Chinese medicine, "liver and eyes co-recover" occurs. "Liver and eyes co-damage and co-recover" can be explained through the "co-material basis and co-action mechanism". On this basis, the research group tentatively proposed that the liver and eyes had "four common characteristics" (4CCs), namely "co-damage, co-recover, co-material basis, and co-action mechanism" from the theoretical connotation of traditional Chinese medicine, clinical practice, and molecular biology. Additionally, the group also took the intervention of Prunella vulgaris, traditional Chinese medicine, for removing liver fire and improving eyesight on immune liver injury (ILI) and allergic conjunctivitis (AC) as examples to analyze 4CCs. This project aims to deeply analyze the scientific connotation of the theory of "liver opens at the eyes", reveal the common characteristics and biological essence of liver and eyes, explore a new research paradigm of "liver and eyes co-recover", and provide a reference for the study of common problems of multi-organ associated diseases.

Malaria, one of the major global public health events, is a leading cause of mortality and morbidity among children and adults in tropical and subtropical regions(mainly in sub-Saharan Africa), threatening human health. It is well known that malaria can cause various complications including anemia, blackwater fever, cerebral malaria, and kidney damage. Conventionally, cardiac involvement has not been listed as a common reason affecting morbidity and mortality of malaria, which may be related to ignored cases or insufficient diagnosis. However, the serious clinical consequences such as acute coronary syndrome, heart failure, and malignant arrhythmia caused by malaria have aroused great concern. At present, antimalarials are commonly used for treating malaria in clinical practice. However, inappropriate medication can increase the risk of cardiovascular diseases and cause severe consequences. This review summarized the research advances in the cardiovascular complications including acute myocardial infarction, arrhythmia, hypertension, heart failure, and myocarditis in malaria. The possible mechanisms of cardiovascular diseases caused by malaria were systematically expounded from the hypotheses of cell adhesion, inflammation and cytokines, myocardial apoptosis induced by plasmodium toxin, cardiac injury secondary to acute renal failure, and thrombosis. Furthermore, the effects of quinolines, nucleoprotein synthesis inhibitors, and artemisinin and its derivatives on cardiac structure and function were summarized. Compared with the cardiac toxicity of quinolines in antimalarial therapy, the adverse effects of artemisinin-derived drugs on heart have not been reported in clinical studies. More importantly, the artemisinin-derived drugs demonstrate favorable application prospects in the prevention and treatment of cardiovascular diseases, and are expected to play a role in the treatment of malaria patients with cardiovascular diseases. This review provides reference for the prevention and treatment of malaria-related cardiovascular complications as well as the safe application of antimalarials.

Objective: To investigate the clinical value of observing perioperative changes of myeloperoxidase (MPO) and neutrophil elastase (NE) in coronary artery circulation in patients underwent valve replacement surgery. Methods: This perspective cohort study was performed in patients who underwent valvular surgery in Nanjing Drum Tower Hospital and Fuwai Hospital from June 2021 to June 2022. Patients were divided into perioperative myocardial injury group and age-, sex- and type of cardiac procedure-matched non-perioperative myocardial injury control group in the ratio of 1∶1. Perioperative myocardial injury was defined as cardiac troponin T (cTnT)>0.8 μg/L on the first postoperative day (POD), and the cTnT level on the second POD increased by more than 10% compared with the cTnT level on the first POD. During the operation, blood samples were collected from the coronary sinus before clamping ascending aorta, and within 5 minutes after de-clamping ascending aorta. Then, the levels of MPO and NE on coronary sinus were continuously measured. The death, severe ventricular arrhythmia, pneumonia, re-intubation, repeat cardiac surgery, extracorporeal membrane oxygenation (ECMO), intra-aortic balloon pump (IABP), continuous renal replacement therapy (CRRT), mechanical ventilation time and the duration of intensive care unit (ICU) were recorded. The levels of MPO and NE and the incidence of clinical outcomes were compared between the myocardial injury group and the control group. The independent risk factors of myocardial injury were analyzed by multivariate logistic regression. Results: A total of 130 patients were enrolled, aged (60.6±7.6) years old, with 59 males (45.4%). There were 65 patients in the myocardial injury group and 65 patients in the control group. During hospitalization, there was no death, ECMO, IABP and CRRT cases in both groups. Compared with the control group, the incidence of severe ventricular arrhythmia (13.8%(9/65) vs. 3.1%(2/65), P=0.03), pneumonia (20.0%(13/65) vs. 3.1%(2/65), P=0.03), re-intubation (6.2%(4/65) vs. 0, P=0.04) was significantly higher in myocardial injury group. The mechanical ventilation time (16.8(10.7, 101.7) h vs. 7.5(4.7, 15.1) h, P<0.01), and the duration of ICU (3.7(2.7, 18.9) vs. 2.7(1.8, 6.9)d, P<0.01) were significantly longer in myocardial injury group compared with the control group. There was no significant difference in the levels of MPO and NE in coronary sinus blood between the two groups before aortic clamping (all P>0.05). However, MPO ((551.3±124.2) μg/L vs. (447.2±135.9) μg/L, P<0.01) and NE ((417.0±83.1)μg/L vs. (341.0±68.3)μg/L, P<0.01) after 5 min aortic de-clamping were significantly higher in myocardial injury group than in the control group. Multivariate logistic regression analysis showed that the levels of NE (OR=1.02, 95%CI: 1.01-1.02, P<0.01), MPO (OR=1.00, 95%CI: 1.00-1.01, P=0.02) and mechanical ventilation time (OR=1.03, 95%CI: 1.01-1.06, P=0.02) were independent risk factors of myocardial injury in patients after surgical valvular replacement. Conclusion: Perioperative myocardial injury is related poor clinical outcomes, perioperative NE and MPO in coronary artery circulation are independent risk factors of perioperative myocardial injury in patients undergoing valve replacement surgery.

Objective: To analyze the survival of newly diagnosed malignant tumors in cancer registration areas of Hubei Province from 2013 to 2015. Methods: From January 1, 2013 to December 31, 2015, all newly diagnosed malignant tumors were collected from cancer registration areas in Hubei Province, and patients were followed up using a combination of active and passive methods. Cancer survival was analyzed using the strs package in Stata software. Observed and expected survival were calculated using the life table and Ederer Ⅱ methods, and the difference in survival rate of patients with different sex, age, urban and rural areas and different cancer species was compared. Results: From 2013 to 2015, 83 987 new malignant tumors were diagnosed in cancer registration areas in Hubei Province, including 45 742 males (54.46%) and 38245 females (45.54%). The overall 5-year relative survival rate was 41.46%, 34.43% for men and 49.63% for women. With the increase of age, the observed survival rate and relative survival rate of patients of different genders showed a decreasing trend. The 5-year relative survival rate of patients with malignant tumors was 47.58% in urban areas and 26.58% in rural areas. The observed survival rate and relative survival rate in rural areas were significantly lower than those in urban areas. The overall 5-year relative survival rates for common malignancies were 20.61% for lung cancer, 15.36% for liver cancer, 22.89% for esophageal cancer, 34.92% for gastric cancer, and 54.87% for colorectal cancer. In addition, the 5-year relative survival rates of common malignant tumors in women were 78.65% for breast cancer and 52.55% for cervical cancer. Conclusions: In Hubei Province, the survival rate of malignant tumors is different among different genders, regions, age groups and cancer species. Prevention and treatment and health education should be strengthened for malignant tumor patients in rural areas and those with high incidence and low survival rate such as liver cancer and lung cancer, and relevant strategies should be formulated according to the gender and age distribution characteristics of different cancer species.
