An endophytic bacterium strain EBS05 from Cinamonum camphra was identified as Bacillus subtilis by morphological taxonomy and sequence analysis of 16S~23S rRNA intergenic spacer regions. Properties of antimicrobial compound produced by EBS05 were assayed. The active compound had the maximum absorbance peak at ?213.5 nm. The antimicrobial activity was stable in solution with pH value from 5 to 8, and decreased significantly in solution with pH value less than 4.0 or more than 9.0. The antimicrobial compound had thermodynamics stability. Its activity changed a little after treated at 60?C~80?C for two hours, and compared with 65% original activity after treated at 1?105 Pa for 30 minutes. The active substance had high resistance to ultraviolet radiation and protease K. Antimicrobial compound was soluble in alcohol solu- tion, which was easily dissolved in methanol and ethanol, but not dissolved in ethyl acetate, acetonitrile and petroleum et al.

Chinese Journal of Information on Traditional Chinese Medicine 2018;25(6):34-38
Objective To discuss the clinical efficacy of Bushen Huayu Sanjie Prescription for the treatment of deficiency of both qi and yin and blood stasis in patients with stage Ⅳ of type 2 diabetic nephropathy. Methods Totally 90 patients with stage Ⅳ of type 2 diabetic nephropathy were randomly divided into treatment group and control group, with 45 cases in each group. The control group was given Western routine therapy, such as low-protein diet, control of body mass, hypoglycemic, antihypertensive, lipid-lowering, anticoagulation, and microcirculation, etc. On the basis of control group,treatment group was given Bushen Huayu Sanjie Prescription,one dosage per day,twice a day, orally. The treatment for both groups lasted for three months. TCM symptom scores, blood glucose, blood lipids, renal function, 24-hour urinary total protein (UTP), and serum transforming growth factor-β1 (TGF-β1) and C-reactive protein (CRP) levels before and after treatment in the two groups were observed. Results The total effective rate of clinical efficacy and TCM efficacy of the treatment group were 80.00% and 84.44%, respectively, and the control group was 62.22%. The treatment group was superior to the control group (P<0.05). Compared with before treatment, TCM symptom scores, blood glucose, blood lipids, renal function, UTP, serum CRP, and TGF-β1 were significantly improved in the two groups (P<0.05). The scores of TCM symptoms, TGF-β1, CRP and UTP in the treatment group were better than that in the control group (P<0.05). Conclusion Bushen Huayu Sanjie Prescription combined with Western routine therapy for the treatment of deficiency of both qi and yin and blood stasis in patients with stage Ⅳ of type 2 diabetic nephropathy has good clinical efficacy, which can delay disease progression by reducing TGF-β1 and CRP, inhibiting renal interstitial fibrosis, and decreasing urinary protein excretion.

AIMTo study the protective effect of sodium pyruvate on ischemia/reperfusion injury following hemorrhagic shock.
METHODSRat models of hemorrhagic shock were built up. When the shed blood was infused, the rats were also randomly provided by one of normal saline, glutathione and sodium pyruvate. Rats were killed 3 hours after the reperfusion, the activity of plasma lactate dehydrogenase (LDH) and glutamic-oxaloacetic transaminase (GOT), the level of tissue malondialdehyde (MDA) and the activity of tissue myeloperoxidase (MPO) were detected. Biopsy specimens were obtained to investigate morphological changes of the myocardial, hepatic, lung and renal tissue.
RESULTSThe activity of plasma LDH and GOT, the level of MDA of hepatic, lung and renal tissue and the activity of MPO of myocardial, lung and renal tissue decreased remarkably in group given sodium pyruvate compared with group given normal saline, and the effect of group given sodium pyruvate was more remarkable than group given glutathione.
CONCLUSIONThese data support the view that sodium pyruvate shows protective effect on ischemia/reperfusion injury following hemorrhagic shock. It is possibly relevant to scavenging of oxygen free radicals, reduction of neutrophil, and anti-inflammatory response.

Objective To evaluate the efficacy and risk of endovascular thrombolysis with Urokinase and Tirofiban in patients with cerebral venous sinus thrombosis (CVST).Methods Nine patients with severe CVST were performed selective intravenous sinus Urokinase and Tirofiban thrombolysis combined with mechanical thrombus maceration in our hospital from January 2009 to January 2011; their clinical data and treatment efficacy were analyzed.Results Normal cerebrospinal fluid (CSF) pressure was noted in 8 patients before discharging from the hospital; DSA indicated that 7 achieved complete recanalization of main branch of the venous sinus,cortical veins and deep vein.Only 1 achieved reeanalization of sinuses partly,and partial compensation was noted in the cortical veins.No operation-related complication was noted during and after the surgery.After thrombolysis,symptoms and signs of 8 patients improved obviously,and headache disappeared in 7 of them with only mild degree in 1; 1 patient died.Conclusion Intravenous sinus Urokinase and Tirofiban thrombolysis is an effective and safe method for patients with potentially catastrophic intracranial dural sinus thrombosis.

Flavonoids are a large family of bioactive compounds widely found in foods and plants. Mang studies have proven the preventive and therapeutic effects of flavonoids in cardiovascular disease.Flavonoids has a wide range of pharmacological effects,including antioxidant,anti-inflammatory,vaso-dilation,avoiding the thrombus formation,improving endothelial function,modifying lipid levels and regulating blood lipids through different mechanisms of action.The cardiovascular protective mechanism of flavo-noids are the enzymes that inhibit the production of oxygen derived free radicals,inhibition of lipid peroxida-tion and inflammatory factor, down-regulation of epoxy synthase activity and the activation of AMPK and nuclear factor kappa B signaling pathway. In this review article we review and summarize the so far acquired knowledge of the most important mechanisms of action of flavonoids,to provide theoretical basis for the research and development of the active monomers in flavonoid and compound preparations.
