Objective: To study the gene expression characteristics of steroid- and catecholamine-synthesizing enzymes in adrenal gland of spontaneously hypertensive rats (SHRs), Goto-Kakizaki (GK) rats and normal Wistar rats with the same traditional Chinese medicine syndromes. Methods: Sixteen-week-old Wistar rats, SHRs and GK rats were used. By the quantitative four diagnosis and syndrome differentiation methods and GeneChip Mouse Exon 1.0 ST Array, we observed adrenal gland gene expressions in normal Wistar rats, qi deficiency Wistar rats, SHRs with qi deficiency and qi excess, GK rats with qi deficiency and qi excess. Differentially expressed genes of steroid- and catecholamine-synthesizing enzymes and their regulatory factors were analyzed. Results: Thirty-one genes were differentially expressed among all syndromes. Hsd3b6 was down-regulated significantly 6.0-fold in GK rats with qi deficiency syndrome and qi excess syndrome, and Cyp11b2 was up-regulated 1.5 times in GK rats with qi deficiency syndrome. Por, Hsd11b2, and Nr2f6 were up-regulated in all syndromes, and Cyp2c23, Cyp4a3, Cyp4a8 and Cyp2e1 were down-regulated. However, Srd5a1 and Nr4a1 were up-regulated only in GK rats, and Lss was down-regulated only in SHRs. Th was up-regulated 1.5 times in SHRs with qi deficiency syndrome, GK rats with qi deficiency syndrome and GK rats with qi excess syndrome. Ddc was up-regulated 1.5 times in GK rats with qi excess syndrome. Dbh was up-regulated 3.0 times in GK rats with qi deficiency syndrome and qi excess syndrome. However, Comt was down-regulated 1.5 times in GK rats with qi deficiency syndrome and qi excess syndrome, and Mao was up-regulated 1.5 times in SHRs with qi deficiency syndrome and qi excess syndrome. Conclusion: Some genes associated with steroid- and catecholamine-synthesizing pathways were differentially expressed in SHRs and GK rats, and the differentially expressed genes may be related to the development of traditional Chinese medicine syndromes.

Abstract: Methodology of syndrome differentiation and syndrome-based treatment in rats and mice has professional characteristics and caters to the research and development of traditional Chinese medicine (TCM). In this paper, the authors introduced their systematic research in five aspects. 1) Rats and mice can be used to simulate TCM clinical practice. Diagnosis and syndrome differentiation can be done to the rats and mice, and information collected by the four diagnostic methods from the experimental animals meets the requirements of treatment based on syndrome differentiation. 2) Standardized and quantified four diagnostic methods and syndrome differentiation for rats and mice can be established, and are operational and applicable for general use. 3) There exists constitution and syndrome diversity in normal rats and mice. A spontaneous syndrome can develop in diseased rats and mice, and it can be accompanied by or even change to another syndrome, similar to that in human beings. 4) There is a complicated material base for syndromes inferred from the different gene expressions and splices in neuroendocrine-immune network. 5) Individualized treatment based on syndrome differentiation, as well as quantified evaluation and comparison of the treatment efficacy can be done in the rat and mouse models of syndromes. The established methodology and criteria for syndrome differentiation and syndrome-based treatment in rats and mice can be used in the following four research fields: 1) syndrome identification on rat or mouse models; 2) research on the basic theories of TCM, such as the research on the viscera manifestation theory, the material base of syndromes, function mechanisms of the treatment based on syndrome differentiation, and the diagnostics of TCM; 3) study in clinical subject of TCM, such as evaluation and comparison of the efficacy of treatment based on syndrome differentiation, protocol optimization of syndrome differentiation and treatment, and preventive treatment of diseases; 4) study in traditional Chinese drugs, such as the research on properties of Chinese herbal drugs, and pharmacological research on Chinese herbal medicines and formulas.

OBJECTIVE: To investigate the effects of Erxian Decoction (EXD), a traditional Chinese compound herbal medicine and its separate prescriptions such as Wenshen Yijing Recipe (WSYJR, a recipe for warming kidney and replenishing essence), Ziyin Xiehuo Recipe (ZYXHR, a recipe for nourishing yin and dispersing fire) and Tiaoli Chongren Recipe (TLCRR, a recipe for regulating thoroughfare and conception vessels) and some extracts from EXD on the levels of LH and FSH in the primary cultured anterior pituitary cells from female rats. METHODS: EXD, its separate prescriptions and traditional Chinese herbal extracts from EXD were added directly to the incubators. The levels of LH and FSH were tested by radioimmunoassay. RESULTS: The levels of LH and FSH in the supernatant of anterior pituitary cells treated by EXD or its separate prescriptions including ZYXHR and TLCRR were increased significantly as compared with those in the blank control. There was a tendency for stimulating the secretions of LH and FSH in the WSYJR-treated group too. Dimethyl sulfoxide as the solvent of icariin and curculigoside could interfere with the results. CONCLUSION: EXD and its separate prescriptions such as ZYXHR and TLCRR can increase the levels of LH and FSH significantly.

BACKGROUND:Percutaneous vertebroplasty is the most widely used method for the treatment of osteoporotic vertebral compression fractures,and most studies have concluded that percutaneous vertebroplasty increases the probability of adjacent vertebral secondary compression fractures in patients with osteoporotic vertebral compression fractures.However,controversy remains regarding the risk factors associated with adjacent vertebral re-fracture caused after percutaneous vertebroplasty. OBJECTIVE:To summarize the influencing factors of adjacent vertebral compression fractures after percutaneous vertebroplasty in patients with osteoporotic vertebral compression fractures,in order to provide a certain reference for reducing the risk of its occurrence as well as formulating the corresponding treatment plan. METHODS:Using"osteoporosis,fracture,percutaneous vertebroplasty,adjacent vertebral compression fractures,risk factors"as the Chinese search terms,"osteoporosis,osteoporotic vertebral compression fractures,percutaneous vertebroplasty,adjacent vertebral compression fractures,risk factors"as English search terms,computerized searches were conducted on CNKI,Wanfang Medical Network,VIP,PubMed,Springer,ScienceDirect,and Elsevier databases.The search timeframe focuses on January 2018 through September 2023,with the inclusion of a few classic forward literature.The literature was screened by reading the titles and abstracts,and 83 papers were finally included in the review. RESULTS AND CONCLUSION:(1)Osteoporotic vertebral compression fractures are one of the most common complications of osteoporosis,placing elderly patients at a significant risk of disability and death.Percutaneous vertebroplasty is a practical and effective treatment for osteoporotic vertebral compression fractures.(2)With the popularity of percutaneous vertebroplasty,its secondary vertebral compression fractures have gradually increased,with adjacent vertebral compression fractures being the most common.(3)Previous studies have only discussed the effects of factors such as bone mineral density,multiple vertebral fractures,body mass index,age,sex,amount of bone cement,cement leakage,and anti-osteoporosis treatment on secondary compression fractures of adjacent vertebrae after percutaneous vertebroplasty,and summarized the number of vertebral fractures,timing of the operation,surgical approach,cement material,diffuse distribution of bone cement,recovery height of the injured vertebrae,and wearing of a support after surgery,which is not yet comprehensive.The analysis of the specific mechanisms of risk factor-induced adjacent vertebral fractures is relatively rare.(4)The results of the article showed that low bone mineral density,advanced age,perimenopausal women,multiple vertebral fractures,excessive recovery of the height of the injured vertebrae,cement leakage,comorbid underlying diseases,and poor lifestyle habits were the risk factors for secondary adjacent vertebral compression fractures after percutaneous vertebroplasty,and that maintaining a normal body mass index,early surgery,bilateral percutaneous vertebroplasty,use of a new type of cement material,an appropriate volume of bone cement injection and uniform cement dispersion,regular anti-osteoporosis treatment,and postoperative brace wearing are protective factors for secondary adjacent vertebral compression fractures after percutaneous vertebroplasty.
