AIM: To assay the pattern of thyroid hormone alternations in systemic inflammatory response syndrome (SIRS) patients. METHODS: 50 SIRS patients were enrolled, divided into two groups as to whether they got MODS. Thyroid hormone measurements were taken, including total T_3 (TT_3), total T_4 (TT_4), free T_3 (FT_3), free T_4 (FT_4) and TSH. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was calculated according to clinical data. Outcome (recovery or deterioration) was recorded, as well as the length of time from the onset of SIRS to the day when thyroid hormones were measured (the duration of SIRS). RESULTS: Euthyroid sick syndrome (ESS) was presented in 45 cases. TT_3 level was negatively correlated with APACHEⅡscore (r=-0.330, P0.05). CONCLUSION: SIRS patients has high possibility to get ESS, which happens more frequently and severely in MODS patients. With the persistence and aggravation of SIRS, there is a progression of thyroid hormone reduction.

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.

Spontaneous abortion is one of the most common complications of pregnancy, and two or more spontaneous abortions in a row are defined as recurrent spontaneous abortion (RSA), of which about half of patients have unknown etiology. However, the pathogenesis of unexplained RSA (URSA) has not been elucidated, and the lack of effective treatment has made it one of the key and difficult points in the field of obstetrics and gynecology. This article conducts a literature review of recent research on URSA and finds that the pathogenesis of URSA is related to the imbalance of immune tolerance at the maternal-fetal interface, apoptosis of trophoblast cells, inhibition of angiogenesis, and activation of immune responses. Immunotherapy (including cell therapy, cytokine therapy, and immunosuppressive intervention), hormone drugs, anticoagulant regimens, and traditional Chinese medicine therapies are commonly used in clinical practice to intervene in URSA, but the safety and effectiveness of some therapies are still controversial.
