The incidence and its growth rate of hypertension are both very high. Its pathology and pathogenesis are complex and unclear,and it does serious harm to human health. Hypertension remains incurable. Chemical medicine has good effect on hypertension,but life-long application and multi-drug combination are required,with significant adverse reactions. Also,complications can′t be effectively alleviated. Traditional Chinese medicine (TCM)guided by traditional theories,can lower blood pressure,improve metabolic abnormalities and reduce complications. Its advantages or potentials have not been fully exploited and clinical application is inadequate. Metabolic hypertension has become the main form of hypertension,and its formation mechanism is mainly related to metabolic abnormalities and insulin resistance,metabolic inflammation and other pathology and pathogenesis. A better understanding of the current status of antihypertensive pharmacology of TCM,especially devel?opment and application of metabolic hypertension models is of great significance for TCM treatment of hypertension,and for exploration of new approaches to hypertension.

The "lung and large intestine being interior-exteriorly related" is one of the classical theories in traditional Chinese medicine, which indicates a close correlation between the lung and large intestine in physiology and pathology, and plays a pivotal role in guiding the treatment of the lung and bowel diseases. Modern medicine has revealed some connections between the lung and large intestine in tissue origin and mucosal immunity, and preliminarily illuminated the material basis and possible regulatory mechanism of the theory. Recently, this theory has been applied to guide the treatment of refractory lung and intestine diseases such as COVID-19 and ulcerative colitis and has obtained reliable efficacy. Existing research results show that the anatomical homogeneity of lung and large intestine promotes the correlation between lung-bowel mucosal immunity, and mucosal immunity and migration and homing of innate lymphocytes are one of the physiological and pathological mechanisms for lung and large intestine to share. Under the guidance of this theory, Chinese medicines with heat-clearing and detoxifying or tonic effects are commonly used in the treatment of the lung and intestinal diseases by regulating lung-bowel mucosal immunity and they can be candidate drugs to treat lung/intestinal diseases simultaneously. However, the existing studies on immune regulation are mainly focused on the expression levels of sIgA and cytokines, as well as the changes in the number of immune cells such as innate lymphocytes and B lymphocytes. While the following aspects need further investigation: the airway/intestinal mucous hypersecretion, the functional changes of pulmonary and intestinal mucosal barrier immune cells, the dynamic process of lung/intestinal mucosal immune interaction, the intervention effect of local pulmonary/intestinal microecology, the correlation and biological basis between the heat-clearing and detoxifying effect and the tonic effect, and its regulation of pulmonary/intestinal mucosal immunity. In this paper, we try to analyze the internal relationship between lung and intestine related diseases from the point of view of the common mucosal immune system of lung and intestine, and summarize the characteristics and rules of traditional Chinese medicine compound and its active ingredients, which have regulatory effect on lung and intestine mucosal immune system, so as to further explain the theoretical connotation of "lung and large intestine being interior-exteriorly related" and provide reference for the research and development of drugs for related diseases.

With the acceleration of aging and the changes of people's lifestyle and environment, the incidence of chronic non-communicable diseases (chronic diseases) in China is increasing, which has become a major public health problem. The number of sub-health people is even more and rising. The thought of treating disease before its onset emphasizes taking precautions against disease and preventing change after disease onset, which is one of the core contents of traditional Chinese medicine (TCM) theory. According to the theory of TCM, health as a dynamic balance of yin and yang and diseases can be prevented and treated by maintaining this balance. The "state adjustment" strategy suggests to treat diseases by adjusting the state of exuberance or decline based on recognizing and distinguishing "state", which has important guiding significance for developing and evaluating the healthcare food produced with Chinese medicinal materials. Healthcare food plays a vital role in health promotion, chronic disease prevention, and quality of life improvement. At present, the healthcare food produced with Chinese medicinal materials in China generally lacks TCM guidance and fails to fully reflect the advantages of TCM. In this study, the development strategy, functional claims, evaluation methods, and existing problems of healthcare food were discussed. Furthermore, with diabetes as an example, the "state adjustment" strategy was introduced into product development and evaluation to provide ideas for promoting the rapid growth of healthcare food with TCM characteristics.

OBJECTIVE:
To investigate the effect of Chinese medicine Wubi Shanyao pills on sexual function of kidney-yang-deficiency mice induced by hydrocortisone.
METHODS:
Male Kunming mice were injected with hydrocortisone for 10 days to prepare the kidney-yang-deficiency model, and administrated with Wubi Shanyao pills (0.91, 1.82, 2.73 g/kg) for 9 weeks. The general behaviors of mice (autonomous activity, grasping power) were observed; sexual behaviors (capture, straddle, ejaculation frequency and incubation period) of mice were detected by mating experiment. The serum levels of cortisol, adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E
RESULTS:
Wubi Shanyao pills increased the number of independent activities, grasping power, capture frequency of model mice and shortened the capture latency (all
CONCLUSIONS
Wubi Shanyao pills can improve the sexual function of mice with kidney-yang-deficiency induced by hydrocortisone, which may be related to regulating the hypothalamus-pituitary-adrenal axis (HPA axis), promoting the proliferation of testicular cells, and inhibiting cell apoptosis.

ObjectiveTo investigate the effect of Yunkang oral liquid on postpartum kidney deficiency in mice. MethodPostpartum mice were randomized into model and low-dose (6 mL·kg-1), medium-dose (9 mL·kg-1), and high-dose (12 mL·kg-1) Yunkang oral liquid groups. The mouse model of postpartum kidney deficiency was established by sleep deprivation combined with forced swimming. Another 9 female ICR mice were selected as the normal control group. The mice were administrated with Yunkang oral liquid during the period of modeling. The levels of estradiol (E2), progesterone (P), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) in the serum were measured by the enzyme-linked immunosorbent assay. The morphological changes of ovaries and uterus were observed by hematoxylin-eosin (HE) staining, and the expression of transforming growth factor (TGF)-β and Smad2/3 was determined by immunohistochemistry and Western blotting. ResultThe mice in the model group showed prolonged estrous cycle, reduced voluntary activity, dorsal temperature, grip strength, and bone strength, and whitening tongue coating. Compared with the model group, Yunkang oral liquid shortened the estrous cycle, increased the voluntary activity, dorsal temperature, grip strength, and bone strength, and alleviated the whitening of tongue coating. Moreover, it elevated the E2 and P levels and lowered the FSH and LH levels in the serum, decreased ovarian follicular atresia rate, promoted uterine repair, and down-regulated the expression of TGF-β and Smad2/3 in the ovarian and uterine tissues. ConclusionYunkang oral liquid can ameliorate postpartum kidney deficiency in mice by regulating the TGF-β/Smads signaling pathway.
