Current advances on the therapeutic potential of scutellarin: an updated review.

Scutellarin is widely distributed in Scutellaria baicalensis, family Labiatae, and Calendula officinalis, family Asteraceae, and belongs to flavonoids. Scutellarin has a wide range of pharmacological activities, it is widely used in the treatment of cerebral infarction, angina pectoris, cerebral thrombosis, coronary heart disease, and other diseases. It is a natural product with great research and development prospects. In recent years, with in-depth research, researchers have found that wild scutellarin also has good therapeutic effects in anti-tumor, anti-inflammatory, anti-oxidation, anti-virus, treatment of metabolic diseases, and protection of kidney. The cancer treatment involves glioma, breast cancer, lung cancer, renal cancer, colon cancer, and so on. In this paper, the sources, pharmacological effects, in vivo and in vitro models of scutellarin were summarized in recent years, and the current research status and future direction of scutellarin were analyzed.

Comparison of the efficacy and safety of Shanhuang Jiangzhi tablets and atorvastatin in the treatment of patients with hyperlipidaemia.

OBJECTIVES: To compare the efficacy and safety of Shanhuang Jiangzhi tablets and atorvastatin in reducing blood lipid levels. METHODS: Patients with hyperlipidaemia admitted to the cardiac centre between January 2019 and December 2020 were included in the study. A total of 1063 patients with hyperlipidaemia took either Shanhuang Jiangzhi tablets (n = 372) or atorvastatin (n = 691) and met the inclusion and exclusion criteria. Clinical data, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol, were retrospectively evaluated after propensity score matching (PSM) analysis. The adverse events were also recorded during the therapy process. RESULTS: Following PSM analysis, both groups were well matched across all parameters. Compared with the baseline, Shanhuang Jiangzhi tablets had greater effects on TC, TG and LDL-C, and the difference was statistically significant (p < 0.001). Furthermore, the results showed that Shanhuang Jiangzhi tablets are similar to atorvastatin in reducing TC and LDL-C, and all p-values were > 0.05. However, the decrease of TG was greater in the Shanhuang Jiangzhi group (p < 0.001). Clinical adverse reactions of Shanhuang Jiangzhi tablets are rare and have no statistical significance compared with atorvastatin (p = 0.682). CONCLUSIONS: Shanhuang Jiangzhi tablets have a higher hypotriglyceridaemic performance than atorvastatin and an equivalent ability to lower TC and LDL-C. In addition, Shanhuang Jiangzhi tablets are a low-risk option for lowering blood lipids.

Corneal characteristics of Mongolian population with type 2 diabetic peripheral neuropathy in inner Mongolia, China: an assessment using corneal confocal microscopy.

OBJECTIVE: To quantify corneal nerve fiber parameters in a Mongolian population with diabetic peripheral neuropathy (DPN) by corneal confocal microscopy. METHODS: This study conducted a comprehensive evaluation of 114 participants from Hulunbuir between January 2020 and December 2021. The participants included healthy controls, Mongolian and Han patients with type 2 diabetes mellitus. Demographic, medical, and laboratory data were collected, and neuropathy was evaluated by confocal corneal microscopy. And compare various parameters between Han and Mongolian were performed using SPSS software. RESULTS: The average waist circumference of Mongolian diabetic patients was larger than that of Han diabetic patients (P < 0.05). The mean HbA1c of Mongolian was 9.30 (8.15, 10.30) %, and that of Han was 8.30 (7.20, 9.40) % (P = 0.023). The average values of Corneal Nerve Fiber Density (CNFD), Corneal Nerve Fiber Length (CNFL) and corneal nerve branch density (CNBD) in Mongolian diabetic patients were significantly lower than those in Han diabetic patients (P < 0.05). The correlation coefficient between CNFL and age was - 0.368. ROC results show that CNBD has a certain diagnostic value for DPN in Mongolian patients with type 2 diabetes and the optimal cut-off point value is 24.99(no./mm2), the sensitivity is 80.0%, and the specificity is 77.8%. CONCLUSION: The corneal confocal microscopy could possibly represent a promising adjuvant technique for the early diagnosis and assessment of PDN in Mongolian T2DM patients.

Feasibility study on evaluating right ventricular diastolic function by new Tei'-Index.

Objective: Doppler-derived myocardial performance index (Tei) has been used in the evaluation of right ventricular (RV) function. However, the usage in isolated diastolic dysfunction is limited.We sought to find a new Tei'-index that is more appropriate for evaluating isolated diastolic dysfunction (IDD) based on the symmetry of cardiac structure and function. Methods: 21 patients with impaired RV relaxation were compared to 44 control subjects. Tei and Tei' including their components, isovolumetric relaxation time (IRT), isovolumetric contraction time (ICT), the ejection time (ET), and RV rapid filling time (RFT) were measured from RV outflow and tricuspid inflow Doppler velocity profiles. Results: Tei-index have no change between IDD group and control subjects (0.21 ± 0.08 vs 0.23 ± 0.07 P[bond, double bond]NS). The Tei'-index was significantly shortened in IDD group(0.24 ± 0.09 vs 0.32 ± 0.12,p＜0.05).The decrease in Tei'-index was due to the prolongation of both IRT and RFT, and in the abbreviation of ICT. Tei'-index cutoff value of ≥0.31 identified impaired RV relaxation with a sensitivity of 50 % and specificity of 86 %.We also find that the Tei'-index correlated well with doppler measures of diastolic parameters like E/A, E/e', DT, which suggests its potential use as a noninvasive indicator of the right ventricular (RV) relaxation in patients with heart failure of different causes. Conclusion: New Tei's index is highly effective and specific in the evaluation of early diastolic dysfunction of right ventricle, and can be used as an indicator for the detection of IDD in clinic.

Association between serum uric acid levels and the prevalence of heart failure due to acute coronary syndrome in Chinese hospitalized patients: A cross-sectional study.

BACKGROUND AND AIMS: Serum uric acid (SUA) may play a role in heart failure (HF). Our study was to find relationships between SUA and the prevalence of HF due to acute coronary syndrome (ACS), and the ethnic-specific relationship between them in an inpatient population. METHODS AND RESULTS: We analyzed 1075 Chinese ACS patients. SUA levels were cut to four groups as Q1 to Q4, according to quartiles. Binary logistic regression models were used to assess associations of SUA with HF due to ACS. Subgroup analysis was performed to find ethnic-specific association between SUA and HF due to ACS. We also performed univariate and multivariate logistic regression analyses taking into account an Italian's cut-off for SUA for HF prognosis stratification. After adjustment for all potential confounders, compared to the lowest quartile, quartiles 2, 3 and 4 had a prevalence OR of 0.69 (0.44-1.08), 1.06 (0.67-1.67) and 2.19 (1.35-3.56), respectively, for the HF due to ACS (p for trend <0.001). Subgroup analyses didn't reveal an ethnic-specific differences between SUA and HF due to ACS. In Han, the highest SUA level was significantly associated with the risk of HF due to ACS. OR with 95%CI for Q4 was 1.85 (1.02-3.37), Q1 as a reference. For Mongolians, the OR with 95%CI for Q4 was 6.82 (1.90-24.50), Q1 as a reference. CONCLUSION: We found positive associations between SUA and the prevalence of HF due to ACS among Chinese patients. No differences exist regarding ethnicity.
