Type 2 diabetes mellitus （T2DM） and hypertension are common and frequent chronic non-communicable diseases， which often coexist in clinical practice， resulting in a large number of cardiovascular events and deaths， and their case fatality rate far exceeds that of other factors such as dyslipidemia and obesity. Based on the diagnostic standards， guidelines， and animal model evaluation methods of T2DM with hypertension at home and abroad， this study summarized， evaluated， and analyzed the characteristics of the existing animal models of T2DM with hypertension based on the clinical symptoms in traditional Chinese and Western medicine. The animal models showing high fitting degrees with the clinical symptoms in Western medicine are mainly established by injection of streptozocin （STZ） in SHR rats in the surgical induction and chemical induction methods and feeding a high-fat and high-salt diet combined with STZ injection in SD rats in the dietary induction methods. The models showcasing high fitting degrees with the clinical symptoms in traditional Chinese medicine （TCM） are mainly established by the surgical induction method. Considering the fitting degrees and the advantages and disadvantages， the ideal modeling method for T2DM with hypertension is the two-kidney， one clip （2K1C） method （a surgical induction method） combined with feeding a high-fat and high-sugar diet and STZ injection. However， the available models lack the characteristics of TCM and the evaluation indicators have poor specificity. This study found that there are few animal models of T2DM with hypertension considering the characteristics of both disease and syndrome， which may be related to the identification and attribution of TCM syndromes in animal macroscopic information. In view of this problem， it is suggested that the evaluation criteria should be established and improved for the animal models combining disease and syndrome， which can help to evaluate the fitting degree of the pathological characteristics of different syndromes in the animal models of T2DM with hypertension. In this way， ideal animal models of T2DM with hypertension can be established to simulate the disease occurrence and development in the human body. The animal models are expected to provide an ideal approach for the further research on the pathogenesis of T2DM and its prevention and treatment with TCM， which is of great significance for the treatment and prevention of T2DM with hypertension and the prognosis of its complications. At the same time， breakthroughs in the basic syndrome models of comorbidities are expected to lay a foundation for the leapfrog development of TCM research.

ObjectiveTo investigate the effect and possible mechanism of Shenfu Injection （参附注射液） on rat cardiomyocyte injury induced by isoproterenol from the perspective of regulating the high mobility group protein B1 （HMGB1）/ Toll-like receptor 4 （TLR4）/nuclear factor κB （NF-κB） pathway through the deacetylation modification of silent information regulator 1 （SIRT1）. MethodsThe optimal concentration and intervention duration of isoproterenol hydrochloride and the optimal intervention concentration of Shenfu Injection were screened out by CCK-8 method. Logarithmically growing H9c2 rat cardiomyocytes were taken at 5×10⁴ cells/well and divided into normal group， model group， Shenfu Injection group， and SIRT1 inhibitor group， with 3 replicates in each group.Except for the normal group， the cells in the other groups were induced by isoproterenol hydrochloride to establish a chronic heart failure cell model. After modeling， the Shenfu Injection group was given Shenfu Injection at the optimal intervention concentration， and the SIRT1 inhibitor group was given 1 μmol/L of SIRT1 inhibitor EX-527， for optimal intervention duration.CCK-8 assay was used to detect the cell activity and calculate the inhibitory rate. ELISA assay was used to detect the nicotinamide adenine dinucleotide oxidation state/ nicotinamide adenine dinucleotide reduction state （NAD+/NADH） in cardiomyocytes. Immunofluorescence was used to detect the immunofluorescence localization of HMGB1 and SIRT1 in cardiomyocytes. Western blotting was used to detect the protein expression of acetylated HMGB1 in cardiomyocytes， HMGB1 in the nucleus and cytoplasm， and SIRT1， TLR4， myeloid differentiation factor 88 （MYD88） and NF-κB p65 in cardiomyocytes. RT-qPCR was used to detect the mRNA expression of SIRT1， HMGB1， TLR4， MYD88 and NF-κB p65 in cardiomyocytes. ResultsThe optimal intervention concentration of isoproterenol hydrochloride was 300 μmol/L， and the intervention duration was 48 hours； 8% was the optimal intervention concentration of Shenfu Injection. Compared to those in the normal group， the cell activity， NAD+/NADH value， nuclear HMGB1 protein expression， cardiomyocyte SIRT1 protein and mRNA expression in the model group decreased， while the cell inhibition rate， cardiomyocyte acetylated HMGB1 and cytoplasmic HMGB1 protein expression， cardiomyocyte TLR4， MYD88， NF-κB p65 protein and mRNA expression all increased （P＜0.05）； fluorescence localization showed that the content of HMGB1 in cardiomyocytes in the model group increased and was localized in both the nucleus and cytoplasm.Compared to the model group and the SIRT1 inhibitor group， the Shenfu Injection group showed significant improvements in all the above indicators （P＜0.05）； fluorescence localization showed that the SIRT1 content increased in the Shenfu injection group， while the HMGB1 content decreased， and was mainly located in the nucleus. ConclusionShenfu Injection can improve myocardial cell damage by increasing SIRT1 expression to reduce the acetylation level of HMGB1， regulating the HMGB1/TLR4/NF-κB pathway and inhibiting the nuclear translocation of HMGB1.

ObjectiveTo study the modeling characteristics of primary dysmenorrhea models in animals and to provide references for the standardization of the primary dysmenorrhea animal models. MethodThe research articles on animal models of primary dysmenorrhea were retrieved to establish a database. The types of experimental animals， modeling methods， modeling cycle， drug dosage， drug injection methods， high-frequency detection indicators， positive drug types， etc.， were summarized and analyzed. ResultA total of 171 research articles that met the criteria were included. The animals for primary dysmenorrhea model induction were mainly SD rats， Wistar rats， and Kunming mice. Most of them were prepared by combining estradiol and oxytocin with the modeling cycle of 9 d≤t≤12 d. In terms of drug dosage for rats， estradiol benzoate was 0.5 mg·d^-1 on the 1st and 10th days and 0.2 mg·d^-1 on the 2^nd to 9^th days， while oxytocin at 2 U·d^-1 was the most common. In terms of drug dosage for mice， diethylstilbestrol at 2 mg·kg^-1·d^-1 and oxytocin at 20 U·kg^-1·d^-1 were the most common. In terms of injection methods， oxytocin was mainly administered by intraperitoneal injection and estradiol （estradiol benzoate and diethylstilbestrol） by subcutaneous injection. The detection indicators were mainly behavioral indicators of the writhing assay or the related biochemical indicators in the uterus or serum by enzyme-linked immunosorbent assay. The positive western medicines were dominated by ibuprofen and Chinese medicines by Tongjingbao. ConclusionAlthough primary dysmenorrhea animal models have become a hot topic， the existing reviews are not comprehensive， and the modeling standards and traditional Chinese medicine （TCM） syndrome evaluation are inadequate. By summarizing and analyzing the big data of the animal models， this study proposed some specific views to provide guidance and references for establishing the standard and ideal animal models of primary dysmenorrhea， so as to carry out research on this disease.
