Pretreatment with Danhong injection protects the brain against ischemia-reperfusion injury

Danhong injection （DHI）, a Chinese Materia Medica standardized product extracted from Radix Salviae miltiorrhizae and Flos Carthami tinctorii, is widely used in China for treating acute isch-emic stroke. In the present study, we explored the neuroprotective efficacy of DHI in a rat model of temporary middle cerebral artery ocdusion, and evaluated the potential mechanisms under-lying its effects. Pretreatment with DHI （0.9 and 1.8 mL/kg） resulted in a significantly smaller infarct volume and better neurological scores than pretreatment with saline. Furthermore, DHI significantly reduced the permeability of the blood-brain barrier, increased occludin protein expression and decreased neutrophil infiltration, as well as profoundly suppressing the upreg-ulation of matrix metallopeptidase-9 expression seen in rats that had received vehicle. Matrix metallopeptidase-2 expression was not affected by ischemia or DHI. Moreover, DHI （1.8 mL/kg） administered 3 hours after the onset of ischemia also improved neurological scores and reduced infarct size. Our results indicate that the neuroprotective efficacy of DHI in a rat model of cerebral ischemia-reperfusion injury is mediated by a protective effect on the blood-brain barrier and the reversal of neutrophil infiltration.

Network Pharmacology-Based Dissection of the Bioactive Compounds and Pharmacological Mechanisms of Yiqi Fumai Lyophilized Injection for the Treatment of Heart Failure

Objective:Yiqi Fumai Lyophilized Injection(YQFM),a Chinese medicine injection,has been widely used for the treatment of cardiovascular diseases,especially heart failure(HF).However,bioactive compounds and underlying mechanisms of YQFM in treating HF remain poorly understood.Materials and Methods:Network pharmacology was employed to investigate the bioactive compounds and mechanisms of YQFM.A compound-target network was constructed to screen bioactive compounds based on contribution index calculation.Then,an adriamycin-induced HF rat model was established to evaluate the cardio-protective effects of YQFM by hematoxylin and eosin staining and enzyme-linked immunosorbent assays.Results:Network pharmacology indicated that YQFM may alleviate HF through 36 compounds and 109 targets.Particularly,ginsenosides Rb1,Rg1,Re,Rf,Rb2,Rh1,schisandrin,and ginsenoside Rc were indicated as the top contributors of YQFM in treating HF.YQFM was predicted to act on multiple targets such as vascular endothelial growth factor A,interleukin-2(IL-2),IL-6,and IL-1β,as well as to regulate signaling pathways such as hypoxia-inducible factor 1,tumor necrosis factor,VEGF,and PI3K-Akt.The pharmacological study suggested that YQFM could attenuate cardiac injury and up-regulate plasma concentrations of VEGFR-1 and NO in HF rats.Ginsenoside Rb1,as the major contributor from network pharmacology analysis,also showed a cardioprotective effect and up-regulation of VEGFR-1 in plasma.Conclusions:Ginsenosides and schisandrin were predicted as the most important contributors to the cardioprotective effect of YQMF.Ginsenoside Rb1 was proved to alleviate HF and increase the plasma concentration of VEGFR-1.

Protection of Salvianolate Lyophilized Injection combined with Xueshuantong Injection (Lyophilized) against focal cerebral ischemia/reperfusion injury in rats through suppression of inflammatory response

Objective： Inflammatory reactions induced by microglia in the brain play an important part in the pathogenesis of focal cerebral ischemia/reperfusion （I/R） injury, resulting in neuronal death. Salvianolate Lyophilized Injection （SLI） and Xueshuantong Injection （Lyophilized） （XST）, which have been widely used in the treatment of acutely cerebral infarction clinically in China, exhibit various biological activities. In this study, the neuroprotective properties of SLI combined with XST in a rat model of middle cerebral artery occlusion- reperfusion （MCAO/R） were investigated. Methods： In this study, male Wistar rats were subjected to 1.5h of middle cerebral artery occlusion followed by reperfusion for 24 h. The rats were randomly divided into the following six groups： normal group （NOR）, model group （MOD）, SLI group （21 mg/kg, SLI）, ）（ST group （100 mg/kg, ）（ST）, SLI combined with XST （XST 100 mg/kg ＋ SLI 21 mg/kg, 1X1S）, and Edaravone （as a positive control drug, 6 mL/kg, EDI）, once a day for 3 d. The neuronal injury, the expression of glial fibrillary acidic protein （GFAP） and ionized calcium binding adaptor molecule 1 （IBA-1）, and the changes of pro-inflammatory mediators interleukin- 6 （IL-6）, tumor necrosis factor alpha （TNF-α） and anti-inflammatory mediator interleukin-10 （IL-10） were observed. Results： 1X1S treatment significantly increased the number of neuron, compared with the MOD group, SH group and XST group. Gliosis （GFAP and IBA-1） and expression of pro-inflammatory mediators IL-6 and TNF-a were significantly reduced. Meanwhile, 1XIS significantly increased the expression of anti- inflammatory mediator IL-10 in the brains of MCAO/R rats, compared with the MOD group, SLI and XST groups. SLI and XST also remarkably down-regulated the expression of IL-6 and TNF-α compared with the MOD group. Conclusions： This study shows that SLI combined with XST （1X1S） can protect cerebral ischemia- reperfusion injury due to its anti-inflammatory property, and may provide a potential promising new therapeutic strategy for acute ischemic stroke.

Xueshuantong for Injection(Lyophilized,注射用血栓通)Alleviates Streptozotocin-Induced Diabetic Retinopathy in Rats

Objective To investigate the ameliorate effect and underlying mechanism of Xueshuantong for Injection(Lyophilized,注射用血栓通,XST)in streptozocin(STZ)-induced diabetic retinopathy(DR)rats.Methods Diabetes mellitus(DM)model was induced by intraperitoneal(i.p.)injection of STZ(60 mg/kg)in Sprague-Dawley rats.Diabetic rats were randomized into 3 groups(n=10)according to a random number table,including DM,XST50 and XST100 groups.XST treatment groups were daily i.p.injected with 50 or 100 mg/kg XST for 60 days,respectively.The control and DM groups were given i.p.injection with saline.Blood glucose level and body weight were recorded every week.Histological changes in the retina tissues were observed with hematoxylin-eosin staining.Apoptosis and inflammation related factors,including cleaved caspase-3,glial fifibrillary acidic protein(GFAP),tumor necrosis factor-α(TNF-α)and intercellular cell adhesion molecule-1(ICAM-1)were detected by Western blot or real-time polymerase chain reaction.Then,the levels of advanced glycation end product(AGE)and its receptor(RAGE)were investigated.Tight junctions proteins(Zonula occludens-1(ZO-1),Occludin and Claudin-5)of blood-retinal barrier were detected by Western blot.The levels of retinal fifibrosis,transforming growth factor-β1(TGF-β1)-Smad2/3 signaling pathway were evaluated at last.Results There was no signifificant difference in the body weight and blood glucose level between XST and DM groups(P>0.05).Compared with the DM group,XST treatment signifificantly increased the retinal thickness of rats(P<0.05 or P<0.01),and suppressed cleaved caspase-3 expression(P<0.01).XST increased the protein expressions of ZO-1,Occludin and Claudin-5 and decreased the mRNA expressions of matrix metalloproteinase 2(MMP-2)and MMP-9(P<0.05 or P<0.01).Moreover,XST signifificantly reduced the productions of AGE and RAGE proteins in the retina of rats(P<0.05 or P<0.01),suppressed the over-expression of TNF-α,and decreased the elevated level of ICAM-1 in retina of rats(P<0.05 or P<0.01).XST signifificantly reduced the levels ofα-smooth muscle actin(α-SMA),connective tissue growth factor(CTGF),TGF-β1 and phosphorylation of Smad2/3 protein in rats(P<0.05 or P<0.01).Conclusions XST had protective effects on DR with possible mechanisms of inhibiting the inflammation and apoptosis,up-regulating the expression of tight junction proteins,suppressing the productions of AGE and RAGE proteins,and blocking the TGF-β/Smad2/3 signaling pathway.XST treatment might play a role for the future therapeutic strategy against DR.

Anti-fibrotic Effects of Salvia miltiorrhiza and Ligustrazine Injection on LX-2 Cells Involved with Increased N-myc Downstream-Regulated Gene 2 Expression

Objective: To investigate the effects of Salvia miltiorrhiza and Ligustrazine Injection（SML） on proliferation and apoptosis of human hepatic stellate cell LX-2 and the expression of N-myc downstreamregulated gene 2（NDRG2, a tumor suppressor gene）. Methods: HSCs from the LX-2 cell line were cultured in vitro. The proliferative state of different initial LX-2 cell numbers was measured using a 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide（MTT） colorimetric assay. LX-2 cells were plated in 96-well plates at an approximate density of 2.50×10;cells/mL and cultured for 24 h followed by the application of different concentrations of SML（1, 2, 4 and 8 μL/mL）. Cell proliferation was measured using the MTT assay at 24 and 48 h. Apoptosis was detected by flow cytometry at 24 h. LX-2 cells were treated with different concentrations of SML and extracted with protein lysis buffer. The levels of NDRG2 and β-catenin were measured by Western blot. Results: With the exception of the 1 and 2 μL/mL concentrations, 4 and 8 μL/mL SML inhibited cell proliferation in a concentration-dependent manner at 24 and 48 h（P<0.05）. With the exception of the 1 and 2 μL/mL concentrations, the NDRG2 expression level was greatly increased in a concentration-dependent manner. However, the level of β-catenin was unaffected. Conclusion: SML inhibit LX-2 cell proliferation in a concentration-dependent manner, and the mechanism may be associated with NDRG2 over-expression.

Objective： To observe the effect of Salvia miltiorrhiza Injection （SMI） in treating traumatic hyphema （TH） and the opportune time for its application. Methods： A retrospective study was conducted in 174 patients with TH （all with a single eye wounded）, of whom 92 patients were treated with dicynone and 82 with SMI, and their status of recurrent or aggravated hemorrhage within 5 days after trauma were analyzed. Further, a prospective study was conducted in 76 TH patients （all with a single eye wounded）, who were treated with dicynone though they had hyphema 5 days after treatment. After the dicynone medication was discontinued, 39 of them were treated with Sl, but 37 were not. The status of hyphema absorption was observed. Results： The retrospective study showed that the number of cases with recurrent or aggravated bleeding in the SMI-treatment group was much more than that in the dicynone- treated group （Z=-2.531, P=0.011）. On the other hand, the prospective study showed that the status of hyphema absorption among the SMI-treated patients was significantly better than in those untreated with SMI （Z=-2.642, P=0.008）. Conclusion： SMI shows an effect of promoting the absorption of TH, and SMI treatment is worthy of being spread in clinical practice.

目的观察丹参川芎嗪联合针刺疗法对急性颅脑损伤患者神经功能及炎症因子表达水平的影响。方法选取2022年9月至2023年9月在湖南中医药高等专科学校附属第一医院急诊科住院的急性颅脑损伤患者80例,按照随机数表法将其分为对照组和观察组,每组各40例。对照组予以西医常规治疗;观察组在对照组基础上予以丹参川芎嗪注射液5 ml,1次/d,静脉滴注,并配合针刺疗法,两组疗程均为7 d。观察两组患者治疗前后的肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)、C反应蛋白(CRP)、日常生活能力(ADL)评分、神经功能评分(NIHSS)变化。结果80例患者在治疗观察过程中脱落5例,最终入组75例,对照组37例,观察组38例。治疗后,两组总有效率比较,差异无统计学意义(P>0.05)。治疗后,观察组NIHSS及ADL评分低于对照组,差异有统计学意义(P<0.05);观察组IL-6、IL-8、TNF-α及CRP表达水平低于对照组,差异有统计学意义(P<0.05)。结论丹参川芎嗪注射液联合针刺疗法能够有效降低急性颅脑损伤患者的炎症因子水平,减轻患者神经功能缺损,提高患者日常生活自理能力,临床疗效良好。
