BACKGROUND:Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil has achieved good clinical efficacy, but the underlying mechanism remains unclear. OBJECTIVE: To study the effects of Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil on the hypothalamic-pituitary-adrenal axis negative feedback function in the chronic depressed rats, and to explore anti-depression mechanisms of Mongolian Pharmaceutical Betel Shisanwei ingredients pil. METHODS: Eighty male Wistar rats were randomly divided into ten groups according to the sugar consumption test (with eight rats in each group): normal control group, model group, fluoxetine group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups, RU486 group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups. Except normal control group, the other groups were treated with the chronic unpredictable mild stress stimulation combined with lonely rising, to establish depression models. In the meantime, rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups were given oral gavage of Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) for 28 days; rats of the normal control group and model group were intragstricaly administered with sodium carboxymethyl celulose; rats of RU486 group were given abdominal subcutaneous injection of RU486 from day 21 after modeling; rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups were intragstricaly administered with Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) and subcutaneous injection of RU486 from day 21. RESULTS AND CONCLUSION:Compared with normal control group, cortisone content increased significantly (P < 0.05), the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland decreased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression increased significantly in the model group and RU486 group. Compared with model group, cortisone content decreased, the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland increased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression decreased significantly in rats treated with Betel Shisanwei Ingredients Pil. Compared with RU486 group, Betel Shisanwei Ingredients Pil administration led to changed in cortisone content, glucocorticoid receptor mRNA expression in hippocampus, hypothalamus and pituitary gland, as wel as hypothalamic corticotrophin releasing hormone mRNA expression. Experimental findings indicate that, Betel Shisanwei Ingredients Pil can directly regulate excessive secretion of glucocorticoid, and improve the dysfunction of hypothalamic-pituitary-adrenal axis central negative feedback through increasing glucocorticoid receptor mRNA expression and decreasing corticotropin releasing hormone mRNA expression. After the hypothalamic-pituitary-adrenal axis negative feedback pathway is blocked, the effect of Betel Shisanwei Ingredients Pil is weakened.

Objective To observe the effects of electro-acupuncture on the E-selectin and resistin protein expression in the hippocampus of rats of chronic stress depression;To explore the role and mechanism of electro-acupuncture in the micro-environment of brain with depression. Methods 40 Fourty rats were randomly divided into four groups:blank group, model group, model+EA group, and model+fluoxetine group by using chronic stress combined with solitary raising methods, 10 rats in each group. Electro-acupuncture intervention was used 1 hour before the modeling. Electro-acupuncture was given at points Baihui (Du 20) and Yintang (Extra) for twenty minutes (2 Hz, 0.6 mA) every day. Fluoxetine was given at the volume of 5 mL/kg, dosage of 10 mg/kg. E-selectin and resistin protein expression in hippocampus were determined by biotin label-based antibody array. Results Compared with the blank group, the protein expression of E-selectin and resistin in the model group increased (fold change=1.23, 1.22). Compared with the model group, E-selectin and resistin expression decreased (fold change=0.65, 0.62;fold change=0.76, 0.65). Conclusion Electro-acupuncture intervention could down-regulate E-selectin and resistin expression in the hippocampus of chronic stress depression model.

Betel Shi-San-Wei Ingredients Pill(BSSWIP) was first recorded in the 19th century writings Meng-Yi Jin-Gui with the name of Gao-Y ou-13. The name of BSSWIP was first recorded in the book of the 1977 edition of the Drug Standard of the Jilin Province, which was formerly known as Tai De Hu Ran Gu Lu Ge Qi Nai Ran Ta, Se Me Ji De Ji De, and etc. Although in the book of Tong-Wa-Ga-Ji-De, Se Me Ji De Ji De was documented, it was the same name of different compositions. It had no original relation with BSSWIP. In different periods, the BSSWIP was consisted of 13, 14 or 15 kinds of herbs. There were at least five different types of herbs appeared in the Gao-Y ou-13. The evolution of prescription was mainly from the 19th century to the first half of the 20th century. There was no major change on prescription composition and proportion since 1971. Among them, 10 kinds of herbs, which were Bing-Lang, Guang-Zao, Mu-Xiang, Ding-Xiang, Rou-Dou-Kou, Zi-Nao-Sha, Gan-Jiang, Bi-Ba, Hu-Jiao, and Chen-Xiang were fixed. The ratio of single herbal medicine changed the most was Zhi-Cao-W u, which was followed by Mu-Xiang, Ding-Xiang and Chen-Xiang. There were no marked sources of BSSWIP in the recording of the Drug Standard of the Jilin Province and the Mongolian Medicine V olume·Ministry of Health of the People's Republic of China. The composition and proportion were considered to be from the book Meng-Y i Jin-Gui according to notes of Standards on Mongolian Patent Medicine in Inner Mongolia. Recordings of three standards are in consistence with the Meng-Y i Jin-Gui on Gao-Y ou-13 except for Y e-Mao-Niu Xin and the different ratio of Zhi-Cao-W u. In the appendix of the Standards on Mongolian Patent Medicine in Inner Mongolia, it marked the differences from the original prescription. Therefore, the other two criteria should also mark the similarities and differences compared with the original prescription properly.

Objective:To investigate the status of Corona Virus Disease 2019 (COVID-19) health literacy and associated factors in Inner Mongolia Autonomous Region.Methods:Based on the multi-stage stratified sampling method, the questionnaire survey of health literacy of COVID-19 were carried out in 55 599 local residents from12 prefecture-level cities of Inner Mongolia Autonomous Region between March 10 and 15, 2020. The questionnaire in details included not only knowledge, attitude and behavior, but also mental health, their scores were calculated using Decimal method. A ≥80% of the correct answer rate of the survey content was regarded as qualified for health literacy. There were 51 722 (93.0%) valid questionnaires, according to the ratio of medical staff to non-medical staff, 32 529 questionnaires were selected for analysis. The health literacy level was defined according to the proportion of qualified people.The credibility and availability of the questionnaires were evaluated by Cronbach′s α coefficient and KMO test. The associated factors were analyzed by Pearson χ 2 test and logistic regression. Results:In Inner Mongolia Autonomous Region, the whole level of health literacy of COVID-19 was 85.7%, and their scores were (26.30±2.48). Knowledge, attitude, and behavioral literacy levels were 61.6%, 95.6%, and 96.8%, respectively. Compared with the population of 15-25 years old, the health literacy level of 46-65 years old was the highest ( OR=2.00, 95% CI: 1.78-2.24). The health literacy level of medical staff group ( OR=2.54, 95% CI: 1.30-4.95) was far higher than the non-medical staff group; the population with college or above education level ( OR=10.22, 95% CI: 9.19-11.36) was significantly higher than the population with education level below college. The degree of anxiety was negatively correlated with education level. Conclusions:The health literacy level of COVID-19 in residents in Inner Mongolia Autonomous Region is relatively high, but the level of knowledge literacy needs to be improved. The main factors affecting the health literacy of COVID-19 among Inner Mongolia residents are age, occupation and education level.
