Objective:To observe the effect of Naringin on neuronal apoptosis in mice with memory consolidation disorderinduced by sodium nitrite.Methods:Fifty mice were randomly divided into blank group, model group, standardized protocol group, high-dose Naringin group and low-dose Naringin group, with 10 mice in each group. The standardized protocol group was given Donepezil 1 mg/kg, the Naringin high and low dose groups were gavaged with Naringin solution 100 and 50 mg/(kg·d), blank group and model group were gavaged with equal volume of distilled water once a day for 21 days. The model was established on the 22nd day. The blank group was intraperitoneally injected with normal saline, and the other groups were intraperitoneally injected with 100 mg/(kg·d) sodium nitrite solution for 7 days. The cognitive ability of mice in each group was evaluated by platform jumping test, and the hippocampal synaptic structure was observed by electron microscope. The contents of acetylcholine (ACh), SOD, MDA and NO in hippocampus and the activity of choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) was detected by ELISA. The expression of N-methyl-D-aspartate receptor (NMDAR), glutamine receptor 2 (GluR), calcium/calmodulin dependent protease Ⅱ (CaMK Ⅱ), Caspase-3, Bcl-2 and Bad proteins in hippocampus of model mice were detected by Western blot.Results:The number and morphology of hippocampal neurons were normal, nucleus, mitochondria, rough endoplasmic reticulum and synaptic membrane of hippocampal neurons in high-dose Naringin group were clear. Compared with the model group, the latency of mice in the high-dose Naringin group was prolonged and the number of errors was reduced ( P<0.01). The levels of MDA and NO in hippocampus of mice in the high-dose Naringin group significantly decreased ( P<0.01), and the activity of SOD significantly increased ( P<0.01). The content of ACh (23.682 ± 2.835 μg/mg prot vs. 14.939 ± 2.901 μg/mg prot), ChAT (163.302 ± 21.278 U/g vs. 89.612 ± 11.497 U/g) increased, AChE (0.367 ± 0.015 U/mg prot vs. 0.471 ± 0.014 U/mg prot) activity decreased ( P<0.01); The expression of Bad (0.441 ± 0.010 vs. 0.633 ± 0.010), Caspase-3 (0.425 ± 0.036 vs. 0.537 ± 0.024) significantly decreased, and the expression of Bcl-2 (0.890 ± 0.014 vs. 0.727 ± 0.009) significantly increased ( P<0.01); The expression of CAMKⅡ (1.043 ± 0.037 vs. 1.475 ± 0.043) significantly decreased ( P<0.01), and the expression of NMDAR1 (0.407 ± 0.037 vs. 0.345 ± 0.012), GluR2 (1.125 ± 0.033 vs. 0.664 ± 0.023) significantly increased ( P<0.01). Conclusion:Naringin could play the role of protecing the neuron and improving the cognition of mice with memory consolidation disorder by regulating the balance of ACh and glutamate system and reducing neuronal apoptosis and antioxidant stress.

Objective To collect information from the traditional Chinese medicine(TCM)four diagnostic information of patients with coronary heart disease(CHD)and to observe the characteristics of their Chinese medicine syndrome factor at different ages,to provide an objective basis for the Chinese medicine treatment of patients with CHD at different ages.Methods The TCM Four Diagnostic Information Collection Scale for CHD developed by the group was used to collect the four diagnostic information of patients with coronary heart disease,and the syndrome elements were extracted according to the syndrome differentiation standard to observe the distribution of syndrome elements at different ages.Results CHD is located in the heart and accompanied by liver,kidney,stomach,lung and other organs.Qi deficiency is the most common syndrome factor,followed by phlegm turbidity,yin deficiency,blood stasis and qi stagnation.Among the syndrome elements of disease location,the heart and liver were the most common in the young group,and the heart and kidney were more common in the middle-aged group and the elderly group.Among the syndrome elements of disease nature,qi deficiency was more common in the young group,phlegm turbidity and qi stagnation were more common in the empirical group,and qi deficiency and phlegm turbidity were the most frequent.In the middle-aged group,qi deficiency was more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and the frequency of qi deficiency and phlegm turbidity and blood stasis was the highest.In the elderly group,qi deficiency and yin deficiency were more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and qi and yin deficiency combined with phlegm turbidity and blood stasis had the highest frequency.Conclusion The combination of syndrome elements in patients with CHD in different age groups has its own characteristics.The young,middle and elderly groups are all visible in the mixture of deficiency and excess,while the young group is the most common with qi deficiency and phlegm turbidity,the middle-aged group is the most common with qi deficiency and phlegm turbidity and blood stasis,and the elderly group is the most common with qi and yin deficiency and phlegm turbidity and blood stasis.With the increase of age,the complexity of the combination of syndrome elements is higher.

Objective : To clarify the distribution of traditional Chinese medicine (TCM) pattern and its associated risk factors after percutaneous coronary intervention (PCI), and evaluate the reporting quality of existing studies to guide future research standardization. Methods: English databases including PubMed, Cochrane Library, and Web of Science, as well as Chinese databases including China National Knowledge Infrastructure (CNKI), China Scientific Journal Database (VIP), and Wanfang Database were searched to retrieve papers about PCI. The time span for the paper retrieval was set from the foundation of the databases to October 1, 2023. Statistical analyses were performed using Stata 12 and Python (V 3.9). The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement was used to assess the reporting quality of included studies. Result: Overall, 1 356 articles were selected, and 40 cross-sectional studies were included with 10 270 participants. The most common TCM patterns before, one to two weeks after, and six months to one year after PCI was Qi stagnation and blood stasis (n = 261, 36.45%), intertwined phlegm and blood stasis (n = 109, 27.18%), and Qi deficiency and blood stasis (n = 645, 37.03%), respectively. Smoking [odds ratio (OR) = 1.15, 95% confidence interval (CI) (0.83 – 1.47), I 2 = 24.7%, P = 0.257], pattern of congealing cold and Qi stagnation [OR = 4.62, 95% CI (1.37 – 7.86), I 2 = 61.6%, P = 0.074], and low-density lipoprotein (LDL) [OR = 1.38, 95% CI (0.92 – 1.85), I 2 = 12.2%, P = 0.286] were risk factors for restenosis. Hypertension [OR = 7.26, 95% CI (3.54 – 14.88), I 2 = 91.6%, P = 0.001], and overweight [i.e., body mass index (BMI) > 23] [OR = 1.20, 95% CI (1.07 – 1.35), I 2 = 85.3%, P = 0.009] were significant risk factors of concomitant anxiety. Conclusion This systematic review andet a-analysis revealed that patients with different TCM pattern types have distinct characteristics and risk factors after PCI. More high-qualitystudies are warranted to provide supportive evidence for future research and clinical practice.
