METHODS Male SD rats were randomly divided into normal group and model group ，with 9 rats in each group. AMI model was established by isoproterenol hydrochloride modeling method. Three rats in each group were selected for model verification. The remaining 6 rats in each group were given SGI （1.2 mL/kg）or equal volum of normal saline via tail vein ；0.3 mL blood was collected through orbital venous bush 0.083，0.167，0.333，0.5，0.75，1，1.5，2，3，5 h after administration. Using luteoloside as internal standard ，the plasma concentrations of ligustrazine hydrochloride ，salvianic acid and rosemarinic acid were determined by ultra performance liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were fitted by WinNonlin 8.1 software，and statistical analysis was performed by SPSS 18.0 software. RESULTS The linear ranges of ligustrazine hydrochloride ，salvianic acid and rosmarinic acid were 0.06-29.96，0.01-5.15 and 0.006-3.09 μ g/mL（all r＞0.99），respectively. The results of methodological investigation were all in line with the requirements of Chinese Pharmacopoeia （2020 edition）. Compared with normal rats ，CLz of ligustrazine hydrochloride in AMI model rats was significantly increased （P＜0.05）；t1/2 and Vz of salvianic acid were significantly prolonged or increased （P＜0.05）；but the cmax and AUC 0－5 h were significantly decreased （P＜0.05）；AUC0－5 h of rosmarinic acid was significantly decreased （P＜0.05）. CONCLUSIONS The exposure levels of salvianic acid and rosmarinic acid in SGI are lower in AMI model rats than in normal rats ，and the elimination of ligustrazine hydrochloride in AMI model rats is stronger than that in normal rats.

Proteomics Analysis of Mechanism of Shenxiong Glucose Injection in Antagonizing H2O2-Induced Oxidative Damage in H9c2 Cells / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Shenxiong glucose injection （SGI） in inhibiting hydrogen peroxide （H2O2）-induced oxidative damage in H9c2 cells by tandem mass tags （TMT）-labeled quantitative proteomics. MethodH9c2 cells cultured in vitro were exposed to H2O2 for inducing oxidative damage. The cell viability was measured by cell proliferation and cytotoxicity assay （MTS）， followed by peptide fractionation by high performance liquid chromatography （HPLC） and protein expression detection in H9c2 cells by ultrahigh performance liquid chromatography-mass spectrometry. MaxQuant （v1.5.2.8） was utilized for data retrieval， and the high-resolution mass spectrometry was conducted to screen out differentially expressed proteins， which were then subjected to gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. The protein expression levels of perilipin 2 （Plin2） and tropomyosin 1 （Tpm1） in cells were measured by Western blot. ResultThe spectral analysis yielded 48 608 specific peptide fragments and 5 903 quantifiable proteins. Compared with the model group，the SGI group exhibited 82 differentially expressed proteins，of which 22 were up-regulated and 60 were down-regulated. GO analysis results showed that the differentially expressed proteins were mainly involved in biological processes such as programmed cell death regulation，regulation of cell proliferation，cardiovascular system development， and cell migration. As revealed by KEGG analysis， these proteins were mainly related to peroxisome proliferator-activated receptor （PPAR），focal adhesion，phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt），and Ras-related protein 1 （Rap1） pathways. Western blot results demonstrated that compared with the model group，SGI significantly increased the Plin2 protein expression and decreased the Tpm1 protein expression （P<0.01），consistent with the proteomics results. ConclusionSGI may inhibit cell apoptosis and antagonize H2O2-induced cell oxidative damage by regulating PPAR，focal adhesion，PI3K/Akt and Rap1 pathways，which should be further verified by subsequent experiments.

Shenxiong Glucose Injection inhibits H_2O_2-induced apoptosis of H9c2 cells by activating PI3K/AKT pathway / 中国中药杂志

The aim of this paper was to explore the mechanism of Shenxiong Glucose Injection antagonizing apoptosis of H9 c2 cells induced by H_2O_2. H9 c2 cells were pretreated with 1. 7%,3. 4% and 6. 8% Shenxiong Glucose Injection,and then H_2O_2 was introduced to induce apoptosis in vitro. Cell viability was detected by MTS assay,morphological changes of apoptosis were observed by AO/EB fluorescence staining,apoptosis rate was detected by Annexin/PI method,cell expression profile was detected by gene chip technology,the mRNA of PIK3 CA,Bcl-2,Bax,caspase-3 and GAPDH were detected by qRT-PCR,the protein expression levels of PIK3 CA,AKT,P-AKT,Bcl-2,Bax and caspase-3 were detected by Western blot,and the contents of LDH and MDA were detected by kit. The results showed that Shenxiong Glucose Injection of different concentrations significantly increased the viability of H9 c2 cells treated with H_2O_2( P<0. 01),and reversed H_2O_2-induced apoptosis( P< 0. 01). The microarray experiments showed that 138 genes were altered in H9 c2 cells after treatment with Shenxiong Glucose Injection. The differential expression fold of PIK3 CA associated with PI3 K/AKT pathway was 3. 59. The results of qRT-PCR and Western blot showed that Shenxiong Glucose Injection could down-regulate the mRNA and protein expression levels of caspase-3( P<0. 01),up-regulate the mRNA and protein expression level of PIK3 CA and Bcl-2( P<0. 01),and up-regulate the phosphorylation levels of AKT( P<0. 01) in H_2O_2-treated H9 c2 cells. The protective effect of Shenxiong Glucose Injection on H_2O_2 cells injury was significantly inhibited by LY294002,a PI3 K/AKT pathway inhibitor. The results suggested that Shenxiong Glucose Injection may inhibit H_2O_2-induced H9 c2 cells apoptosis by regulating PI3 K/AKT signaling pathway.

Methods:A total of 70 adult male rats weighing about 200 g were selected and divided into seven groups. These groups were as follows:1) normal control group (N):rats were injected with 1 ml of normal saline per day;2) single medicine treatment group (D):rats were administered with 1 ml of Salviae Miltiorrhizae Ligus-pyragine Hydrochloride and Glucose Injection per day;3) single irradiation group (Z):rats were exposed to 20 Gy single whole-chest ir-radiation and injected with 1 ml of normal saline per day;4) irradiation with 10 Gy and medicine treatment group (Z10):rats were ex-posed to 10 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day; 5) irradiation with 15 Gy and medicine treatment group (Z15): rats were exposed to 15 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;6) irradiation with 20 Gy and medicine treatment group (Z20a):rats were exposed to 20 Gy single whole-chest irradiation for four weeks, and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;and 7) irradia-tion with 20 Gy and medicine treatment group (Z20b):rats were exposed to 20 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day. Two rats were selected and sacrificed at the end of two, four, six, eight, and ten weeks of irradiation. Samples of blood and lung tissues in rats were obtained. Results:In the group with single irradiation, the tumor necrosis factor-α (TNF-α) and transforming growth factor-β (TGF-β) levels in plasma of rats were higher than those in the other groups. In the group with irradiation and medicine treatment, the TNF-αand TGF-βlevels in plasma were higher than those in the normal control group and single medicine treatment group. In the group with single irradiation for four weeks,some petechial hemorrhages on the surface of the lung were visible to the naked eye. In the groups with medicine treatment, the petechi-al hemorrhages on the surface of the lung visibly reduced. According to the pathological mechanism of lung tissues, the groups with Sal-viae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection exhibited less inflammation than the single irradiation group. Ir-radiation at 20 Gy for four weeks followed by a daily abdominal injection was slightly better than single irradiation, but the effects were not obvious. Conclusion: Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection could prevent the occurrence of lung injury by reducing the TNF-αand TGF-βlevels in plasma.

Objective To explore the action mechanism of shenxiong glucose injection in treatment of acute spinal cord injury(SCI) through observing its effects on the recovery of motor function and the expression of aquaporin-4(AQP-4) in SCI rats.Methods Totally 90 healthy,aduh,Sprague-Dawley rats were randomly divided into a sham operation group (n=30),aSCI group (n=30) and a drug group (n=30).The SCI rat models in both the SCI group and the drup group were established aecording to the modified Allen's method,while the sham operation group was only given laminectomy.After the operation,the drug group was given intraperitoneal shenxiong glucose injection of 30 rnl/kg a day,while the other two groups were injected in the same way with normal saline.The neural function recovery,the pathological changes after SCI and the expressions of AQP-4 were observed 1,3,7,14 and 21 d after the operation using the Tarlov score,the hematoxylin and eosin staining,as well as immunofluorescence techniques and Western blotting.And the correlation of Tarlov scores with AQP-4 expressions was analyzed.Results No significant changes in Tarlov scores were observed in the sham operation group (P ＞ 0.05),while in the SCI group and the drug group,postoperative Tarlov scores decreased significantly.The hindlimb nerve function recovered to some degree with time in the SCI group and drug group.At 3,7,14 and 21 days after the operation,the Tarlov scores in the drug group were significantly higher than the SCI group (P ＜ 0.05).The drug group showed less severe pathological changes,with more residual neurons still visible of nucleoli than the SCI group 21 days after the operation.Compared with the sham operation group,the expression levels of AQP-4 were significantly higher in the SCI group and drug group at all the time points (P ＜ 0.05).However,the expression levels of AQP-4 in the drug group were significantly lower than the SCI group accordingly (P ＜ 0.05).The Tarlov scores were found to be significantly and negatively related to the AQP-4 protein expression levels 3 days(r =-0.523,P =0.003),7 days(r =-0.437,P=0.016),14 days(r=-0.417,P=0.022) and 21 days(r=-0.377,P=0.040)after the operation.Conclusion Injecting shenxiong with glucose can effectively promote the recovery of motor function after SCI,at least in rats.And its mechanism may be that the development of spinal cord edema is prevented and the secondary spinal cord injury alleviated by restraining the expressions of AQ P-4 in the injured areas.
