AIM: To investigate the protective effects of diltiazem (Dil) on liver, pancreas and small intestines in hemorrhagic-shock canines and its mechanism. METHODS: The canines were bled to a mean arterial pressure (MAP) of 5.33-6.67 kPa for 30 min to produce the model of shock. During the shock, the dogs received water-soluble calcium channel blocker Dil or normal saline. The MAP was kept at the level for 90 min, then the total blood which was bled previously was reperfused . They were observed for 240 min. RESULTS: Dil could significantly elevated MAP of the hemorrhagic-shock canines ( P

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Objective To analyze the chemical constituents in the water extract of Bupleuri Radix and investigate the active ingredients of Bupleuri Radix for the treatment of depression.Methods The chemical constituents in the water extract of Bupleuri Radix were identified by Ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS).CORT-induced poorly differentiated PC12 depression cell model was launched,and PC12 cells were pretreated with monomeric compounds from Bupleuri Radix for 24 h.The cell viability and LDH release rate were measured by CCK-8 assy kit and LDH assay kit,respectively.Results A total of 53 compounds were identified in the water extract of Bupleuri Radix,mainly including type Ⅰ,type Ⅱ and type Ⅲsaikosaponins.Among them,saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E,saikosaponin F and 6″-acetyl saikosaponin A contributed the most to the metabolite profile of Bupleuri Radix,and could improve the viability of CORT-induced PC12 cells(P<0.05,P<0.01).Furthermore,saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E and saikosaponin F could decrease the LDH release rate of CORT-induced PC12 cells(P<0.05,P<0.01).Conclusion The major anti-depression active ingredients in Bupleuri Radix may be Saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E and saikosaponin F,which lays a foundation for the research of the quality control and pharmacodynamic material basis of Bupleuri Radix.
