Therapeutic applications of small molecule kinase inhibitors in liver fibrosis / 中国药科大学学报

@#The aberrant activities or overexpression of kinases have been closely linked to the development of many diseases, including liver fibrosis, and kinases have become important therapeutic targets for these diseases. Protein kinases, including tyrosine kinases and serine/threonines protein kinases, and phosphoinositide 3-kinase(PI3K)are involved in the development of liver fibrosis through direct and indirect mechanisms, such as regulating the activation of hepatic stellate cells and intrahepatic angiogenesis. Recent studies have shown that small molecule kinase inhibitors(SMKIs)manifest great potential for treating liver fibrosis by inhibiting cell proliferation and angiogenesis. The present review summarizes the activities of tyrosine kinase, serine/threonine kinase and PI3K in liver fibrosis, as well as the pathway they involved in during the development of liver fibrosis, and the recently reported antifibrotic effects of various SMKIs both on preclinical animal models and on patients with liver fibrosis in clinical trials.

Study on the shift of ocular vestibular evoked myogenic potentials frequency tuning of Meniere′s disease / 中华耳鼻咽喉头颈外科杂志

Objective@#To study the shift of oVEMP frequency tuning of unilateral Meniere′s disease, by analyzing oVEMP of air-conducted tone bursts in various frequencies.@*Methods@#From May 2016 to October 2017, 33 patients with unilateral Meniere′s from Aerospace Center Hospital were tested for oVEMP in 500 Hz and 1 000 Hz air-conducted tone bursts respectively, and 20 healthy subjects(40 ears), matched for age and sex, were used as healthy control. The amplitudes of the N1-P1 wave and the frequency amplitude ratios of 500/1 000 Hz in affected ears, unaffected ears and normal ears were compared; and receiver operating characteristic curve was analyzed for frequency amplitude ratios of 500/1 000 Hz.@*Results@#By the 500 Hz tone-burst stimulus, the provocation rates of the oVEMP were 84.9%(28/33), 93.9%(31/33) and 97.5%(39/40) in affected ears, contralateral ears and the ears of normal controls, respectively. By the stimulus of 1 000 Hz tone-burst, the provocation rates of the oVEMP were 81.8%(27/33), 87.9%(29/33) and 82.5% (33/40) in affected ears, contralateral ears and normal control ears, respectively. Amplitudes of N1-P1 waveforms in 500 Hz air-conducted tone bursts in affected ears were under normal control ears and contralateral ears. There was significant difference between affected ears and healthy control ears (P<0.05). Amplitudes of N1-P1 waveforms in contralateral ears were also significantly smaller than those in normal control ears (P<0.05). There were no significant differences in amplitudes of N1-P1 waveforms between affected ears, contralateral ears and normal control ears in 1 000 Hz tone bursts stimulus(P>0.05). Frequency amplitude ratios of 500/1 000 Hz in affected ears were significantly under contralateral and normal control ears (P<0.05). According to ROC, the frequency amplitude ratio critical value of frequency tuning was set as 1.17, the positive rate of frequency tuning shift in affected ears was 54.5%(18/33) and significantly higher than in contralateral ears(18.2%, 6/33, χ2=9.429, P=0.002) and normal control ears (7.5%, 3/40, χ2=19.530, P=0.000). In contrast, there was no significant difference in the incidence of frequency tuning shift between contralateral ears and normal ears(χ2=1.909, P=0.167).@*Conclusions@#Frequency tuning oVEMP with Meniere′s disease will be changed.Frequency tuning of oVEMP with Meniere′s disease shifts from low frequency region to high frequency region in comparison with healthy people. Frequency amplitude ratio is helpful for diagnosis of Meniere′s disease.

Enzymatic synthesis of mogroside ⅢE / 中国药科大学学报

The aim was to develop the simple preparation method of mogroside ⅢE,and to lay the foundation for the development of the mogroside sweeteners. In the present study,the glycosidase CPU-GH17,which can regio-selectively biosynthesize mogroside ⅢE from mogroside V,was screened from the established library of glycosi-dases. Then,the soluble expression condition of CPU-GH17 in E. coli was exploited by investigating isopropyl β-D-thiogalactoside (IPTG)concentration,culture temperature and induction time,and 0. 4 mmol/L IPTG,15 °C and 12 h was used as optimal condition. The result showed that mogroside V could be completely converted into mogroside ⅢE under the conditions of pH 6. 0,45 °C,3 U/mL enzyme loading,5 mg/mL substrate concentration for 20 h. In conclusion,a biosynthetic system for the regio-selective preparation of mogroside ⅢE by recombinant CPU-GH17 was successfully established and verified at a preparative scale.

Advances of relationship between protein Neddylation and cancer / 中国药科大学学报

Abnormal modification in protein Neddylation is closely related to the occurrence and progression of various tumors. Studies have shown that the level of enzymes participating in Neddylation is higher than that in normal neighboring tissues,so the relationship between Neddylation and cancer has aroused much concern.Ned-dylation has been considered to be a novel anticancer target. Neddylation inactivation by a first-in-class small molecular inhibitor,MLN4924,induces cell cycle arrest,apoptosis,senescence and autophagy in different tumor cells.MLN4924 also exerts significant anticancer effects by inhibiting tumor angiogenesis and regulating the func-tion of immune cells. In this review,the latest progress of protein Neddylation and tumor cell cycle,apoptosis, senescence,autophagy,angiogenesis and regulation of immunocyte were briefly introduced to provide theoretical reference for the development of antitumor drugs targeting Neddylation.

New therapeutic paradigm and concepts for patients with cirrhotic refractory ascites / 中华肝脏病杂志

The activation of renin-angiotensin-aldosterone-vasopressin system is a key factor in the formation of ascites due to splanchnic vasodilation in cirrhosis. In theory, aldosterone antagonists, contraction of blood vessels, vasopressin V2 receptor, and angiotensin receptor antagonists are important targets for the prevention and treatment of cirrhotic ascites. The 15%-20% of patients with cirrhotic ascites that show no response to at least one week’s treatment with potent diuretics (spironolactone 160 mg/d combined with furosemide 80 mg/d) are considered to have refractory ascites. At present, effective treatments for refractory ascites include tolvaptan, large-volume paracentesis (4000-6000 ml/time/day) combined with albumin (4 g/L ascites), ascites ultrafiltration and reinfusion, transjugular intrahepatic portosystemic shunt, and liver transplantation. In the future, with the development of vasoactive drugs, rifaximin, ascites drainage pump, and other new therapies, the treatment of refractory ascites may be more effective to reduce the need for liver transplantation.

Effect of carotid artery flow changes on the stability of plaque and typing characteristics of cerebral infarction / 局解手术学杂志

objective To observe the influence of hemodynamic changes caused by extracranial carotid stenosis on the plaque stability, and analyze the relationship of cerebral infarction classification,criminal artery stenosis degree and plaque stability to offer evidence for evalu-ating nosogenesis,clinical diagnosis,treatment and prevention of cerebral infarction. Methods CDFI,CTA were performed in 168 patients with acute cerebral infarction,some moderate and severe and occlusive carotid artery which were demonstrated by CTA and CDFI were further checked by DSA during convalescence. Totally 168 acute cerebral infarction patients were divided into 5 groups based on the criminal artery stenosis degree. To evaluate the plaque stability and flow field changes with CDFI and CTA,OCSP clinical classification and brain image clas-sification were finished according to CTA. Patients were classified into 4 subtypes,namely cortical infarction,basal ganglion infarction,corona radiata infarction and posterior infarction,according to the lesion distributions. Observe the changes of flow field and stability of plaque,and compare the relationship between different degree of stenosis and the classification of lesion of infarction. Results Among the 168 criminal arteries,there was 17. 9% of normal,22. 6% of mild stenosis,30. 9% of moderate stenosis,14. 8% of severe stenosis,and 14. 3% of occlu-sion,and the moderate stenosis proportion was the highest. When the stenosis degree was over 50%,it may lead to the changes of flow field, speeding up of blood flow,forming of turbulent flow,and increasing of plaque instability in which lipid plaque and admixture plaque was the highest. PACI is the commonest in all moderate groups. Admixture plaque is usually seen in severe stenosis and occlusion, while fibrous plaque is usually seen in mild stenosis. Conclusion Moderate carotid stenosis may lead to the increase of plaque instability as a result of the changes of flow field,and it may prone to artery-artery embolization.
