Chinese Journal of Information on Traditional Chinese Medicine 2006;0(04):-
Objective To establish a method for determination of Ferulic acid in Jiegu Capsule. Method The samples were determined by RP-HPLC on a Hypersil C18 column (4.6 mm?250 mm, 5 ?m). The mobile phase consisted of methanol and 1% acetic acid (33∶67). The detection wavelength was at 320 nm and the flow rate was 1.0 mL/min. Results The calibration curves of Ferulic acid was linear in the range of 6~60 ?g/mL (r =0.999 9). The average recovery was 99.6% and RSD was 1.8%. Conclusion The method is simple and accurate, which can be used for the quality control of Jiegu Capsule.

3.Matrix metalloproteinase-9 and blood-brain barrier damage and neurovascular remodeling after cerebral ischemia
International Journal of Cerebrovascular Diseases 2014;22(8):629-632
Matrix metalloproteinase-9 plays an important role in the blood-brain barrier disruption.Blood-brain barrier disruption may directly influence the neurovascuiar unit repair after cerebral ischemia.An in-depth study of matrix metalloproteinase-9-mediated ischemic brain damage and neurovascular remodeling is expected to open up a new way for the diagnosis and treatment of cerebral ischemia in clinical practice.
4. Advances in the role of Dickkopf (DKK1) in myeloma bone disease and its targeted therapy
Tumor 2011;31(3):273-276
Myeloma bone disease (MBD) with the characteristic of progressing osteolysis, is one of the main clinical manifestations of multiple myeloma (MM). In recent years, it was revealed that a kind of glycoprotein - Dickkopf (DKK1) associated with embryonic development and tumor progression can inhibit the Wnt signal pathway. The DKK1 efficacy in inhibiting the steoblasts and activating the osteoclasts appears to play an important role in MBD. The ongoing MBD-targeting therapies involving DKK1 neutralizing antibody, proteasome inhibitor, vaccine and regulatory factor on the basis of this mechanism have shown some benefit for MBD.

Objective By analyzing academic publications written by young doctors in a University Affiliated Hospital during 2013-2015,todescribe the characteristics and rules,and analyze the influencing factors,and to build a basis for providing better service and making effective incentive policies.Methods Materials were collected from questionnaire survey and administrative departments,SPSS software was used to analyze the relationship between factors and the numbers of academic papers.Results 214 young doctors published 486 papers in 2013-2015.Results show that people with senior titles and supervise the graduate students,as the PIs of research projects,as a research team PI,fixed time for research,belonging to mature science research team,interdisciplinary cooperation,cooperation with other units,would be able to have more publications.Conclusions Management staffs should know that research fund is important to young doctors to start and follow-up their research work;they Should help the research team to develop and mature,should help young doctors to find and integrate into the research team;ensure young doctors have fixed research time by making policy,should help young doctors to form the good habit of research;Strengthen cross disciplinary construction,help young doctors to carry out inter unit and inter professional collaboration.

There are different degrees of cardiac allograft vasculopathy in patients with long term cardiac transplantation. Coronary angiography shows partial or diffuse coronary artery stenosis, which is one of the main causes of death. There are few typical symptoms of angina pectoris because of no autonomic innervation in transplanted heart. The first symptom to the end of the disease is severe congestive heart failure or arrhythmia. So the principles of diagnosis and treatment in long-term survivors should be in accordance with the coronary heart disease treatment. In this paper, we reported a case of anesthesia of a patient underwent stent implantation for abdominal aortic aneurysm after 8 years of cardiac transplantation. The preoperative preparation and perioperative management were performed according to the principle of coronary heart disease. The patient passed through the perioperative period safely.

BACKGROUND:Acute pancreatitis is a common inflammatory disease mediated by pancreatic acinar cel s injury, and is mainly characterized by leukocyte infiltration. N-acetylcysteine can control leukocyte migration and regulate inflammation in some serious inflammatory diseases. OBJECTIVE:To investigate the protective effects of N-acetylcysteine in rat model of acute pancreatitis caused by sodium taurocholate. METHODS:Ninety Sprague-Dawley rats were randomly divided into three groups:normal control group, acute pancreatitis group and N-acetylcysteine group. Except normal control group, acute pancreatitis model was established in the other two groups by retrograde injection of sodium taurocholate into major duodenal papil a. Rats in the N-acetylcysteine group were treated with N-acetylcysteine intravenously through the tail vein. RESULTS AND CONCLUSION:After acute pancreatitis model was established, plasma amylase levels in the models were significantly higher than that in the normal control rats (P<0.05). Interleukin-1β,-6,-10, and tumor necrosis factorαexpression levels were also obviously higher than that in the normal control rats (P<0.05). Immunohistochemical staining demonstrated that N-acetylcysteine was mainly expressed in the islet cel s, and the pancreatic expression of N-acetylcysteine was down-regulated at both the mRNA and protein levels during the course of acute pancreatitis. N-acetylcysteine administration significantly reduced plasma amylase levels, myeloperoxidase activity, pro-inflammatory cytokine production, and pancreas and lung tissue damages. Furthermore, N-acetylcysteine administration did not cause significant inhibition of nuclear factor-κB activation in the pancreas. N-acetylcysteine is capable of improving damage of pancreas and lung, and exerting anti-inflammatory effects in rats with severe acute pancreatitis.
