Acute pancreatitis happens rapidly and leads to patient's condition changing swiftly.Acute pancreatitis may be complicated by acute lung injury (ALI) and acute respiratory distress syndrome (ARDS),or even multiple organ dysfunction syndrome,and the mortality rate has been high.The mechanism of acute pancreatitis with complications of ALI and ARDS is intricate.It involves the uncontrolled inflammatory response,the damage and apoptosis of cell,the role of trypsin,the imbalance of coagulation and fibrinolysis,etc.These respects interrelate with each other,forming a complex network.Further study of mechanism of acute pancreatitis complicated with ALI and ARDS will supply more new target for clinical diagnosis and treatment.

Idiopathic pulmonary fibrosis(IPF), as one of the chronic and complex diseases, is with high incidence and mortality rate. It is also a difficult to treat disease in modern medicine. Traditional Chinese medicine (TCM) syndrome differentiation and treatment embodies characteristics and advantages. In recent years, the collateral disease theory guiding the prevention and treatment of the chronic and complex diseases has become a hot point and frontier in medical research, and achieved certain effects. This article is to summary the structures and functions of pulmonary collaterals based on the collateral disease theory. Combined with clinical manifestations of IPF, we put forward Fei-Re Luo-Y u as the fundamental role in the pathogenesis of IPF in its acute phase to lay the theoretical foundation to the further exploration of syndrome prevention and differentiation on IPF in its acute exacerbation.

Objective To explore the methods to reduce the occlusion of perforating arteries after intracranial stenting of the vertebral artery. Methods Clinical data of 32 cases of Gateway-Wingspan stent implantation for intracranial branch of vertebral artery were retrospectively analyzed. The postoperative stricture and perfusion improvement situation were evaluated, the reason of perforating artery occlusion was analyzed. Results Thirty-two patients were implanted with 33 pieces of Wingspan stent and 1 piece of Apollo bracket. The operation success rate were 100%, and the stenosis rate reduced from (76.6±6.1)%to (27.9±5.2)%. After three months, the transcranial doppler sonography (TCD) and CT angiography were checked, showing no in-stent restenosis in all patients. Two patients occurred the perforating artery occlusion within 24 hours after operation. The possible reason was the change of stability of atherosclerotic plaque at the stenosis and the plaque displacement caused by the mechanical action of the balloon or stent, which may lead to medulla oblongata artery block. After drug and rehabilitation treatment, the symptoms in patients were improved significantly. Conclusion The perforating artery occlusion after stent implantation in intracranial branch of vertebral artery can be prevented by strict evaluation and preoperative preparation, the right selection of intraoperative balloon and stent, which still needs larger sample data to prove.

Transforming growth factor-β (TGF-β) is a multifunctional protein and regulates a wide variety of cellular bio-effects,such as proliferation,differentiation,migration and apoptosis.Studies have proven that TGF-β is one of the important cytokines that promote fibrosis,and it is confirmed to be closely related to the progression of tumor.Smad signaling is the major pathway in which TGF-β fulfills its functions.These years,it has been found that E3 ubiquitin ligases Arkadia can enhance the biological effect of TGF-β signal transduction pathway through Smad signaling pathway.Therefore,it is increasingly attracting public attention.This study will summarize the effects of Arkadia on TGF-β/Smad signal transduction pathway.

Objective To investigate the changes of plasma bone morphogenetic protein-4 (BMP-4) levels in patients with coronary heart disease (CHD) and rosuvastatin intervention effect on BMP-4 level.Methods Fifty-two patients with CHD and 35 health people were enrolled in this study as CHD group and control group.ELISA method was used to detect the concentration of plasma BMP-4.Analyzed the relationship between plasma BMP-4 and blood lipids,flow-mediated dilation (FMD),nitric oxide (NO),cyclooxygenase-2 (COX-2),malondialdehyde (MDA) and superoxide dismutase (SOD).And observed the changing of plasma BMP-4 before and after rosuvastatin intervention.Results Plasma BMP-4 level in CHD patients was (7.53 ± 1.20) μg/L,higher than that of control group ((3.81 ± 0.79) μ g/L,t =3.541,P =0.006).After rosuvastatin treatment,plasma BMP-4 level in CHD patient was decreased from (7.53 ± 1.20) μg/L to (5.40± 0.98) μg/L (t =1.436,P =0.001).Plasma BMP-4 level was positively correlated with COX-2,MDA,low-density lipoprotein cholesterol,total cholesterol (r =0.395,0.350,0.274,0.288 respectively,P ＜ 0.01 or P ＜0.05).But,it was negatively correlated with NO,high-density lipoprotein cholesterol,SOD,FMD (r =-0.291,-0.253,-0.476,-0.320 respectively,P ＜0.01 or P ＜0.05).COX-2,SOD and FMD were independent risk factors of plasma BMP-4 in patients with CHD.Conclusion Oxidative stress and endothelial dysfunction are in patients with CHD.Rosuvastatin treatment can remarkably reduce plasma BMP-4 level,alleviate vascular endothelium injury induced by oxidative stress and improve endothelial function in patients with CHD.

Objective:To establish a method to determine the metabolites in rat kidney tissues by gas chromatography-mass spectrometry (GC-MS) combined with chemometric techniques. Methods:Metabolites were separated and identiifed on HP-5MS column (30 m × 0.25 μm × 0.25 mm). The initial column temperature was 100℃lasting 3 min, and then programmed at 8℃/min to 300℃, maintaining at this temperature for 6 min. hTe internal standard was heptadecanoic acid. hTe grinded kidney tissue was exacted by methanol. hTe supernatant was dried by nitrogen. Atfer the oximation and derivation, the supernatant was analyzed by GC-MS. hTe overlapped peaks were resolved into pure chromatogram and mass spectra with chemometric techniques. Qualitative analysis was performed by comparing the obtained pure mass spectra with those in NIST mass spectra database and certiifcated by the standards and the references. hTe internal method was used for semi-quantitation. Results:A total of 53 compounds were identiifed. hTe main constitutions in the kidney tissue were amino acids, saccharides, fatty acids and urea. Conclusion:hTe combination of methods is rapid and accurate for the analysis of metabolites in the kidney tissue, which provides more information for further study of metabonomics in kidney tissues.

This study was aimed to summarize and analyze acupoint selection rule of acupuncture in the treatment of primary dysmenorrhea in recent years,and to guide acupoint selection and compatibility in clinical practice.Relevant literatures in recent years were retrieved from the China National Knowledge Infrastructure (CNKI) full-text database.And then,literatures involving acupuncture prescriptions were summarized.Data were integrated and input.Finally,the SPSS software was combined to analyze the data of acupoint selection in the acupuncture prescription to achieve the conclusion.The results showed that in the acupuncture treatment of primary dysmenorrhea,the main meridian selections were the Ren Meridian and the Spleen Meridian of Foot Taiyin.The generally used acupoints were SP6-Sanyinjiao,RN4-Guanyuan,SPS-Diji,and etc.The multi-point compatibility therapy was used.It was concluded that although the advantages of acupuncture in the treatment of primary dysmenorrhea are prominent,the pathogenesis is mainly related to the liver,spleen and kidney,which are recognized by most physicians.However,there are still large differences in acupoint compatibility and acupoint selection.Hence,there are still no unified,scientific and standardized diagnosis and treatment standards.Further exploration should be made to guide clinical practice.

This study was aimed to explore the medication rules of Chinese herbal medicine compound in the treatment of primary dysmenorrheal based on data mining.Relevant literatures on Chinese herbal medicine compound in the treatment of primary dysmenorrhea were retrieved from June 2006 to June 2016 in the Chinese Journal Full-text Database (CNKI) to establish a literature database.The Excel 2010,SPSS 22.0 and SPSS Modeler 14.2 software were used in the frequency analysis,cluster analysis,association analysis,and etc.The results showed that literatures related to Chinese herbal medicine compound in the treatment of primary dysmenorrhea,there were 74 compound formula and 76 kinds of Chinese herbal medicine involved.Angelica was the core single Chinese herbal medicine.Chinese herbal medicine with high-frequency usage was the type of removing blood stasis,invigorating qi and blood.Cluster analysis can form 5 clustering combination.Primary dysmenorrhea was mainly clustered to two syndromes,which were qi and blood deficiency with blood stasis,liver and kidney deficiency with qi stagnation and blood stasis.The association rules analysis showed that there were a total of 25 rules,with the most common combination of two or multiple combination from four kinds of Chinese herbal medicine,including Angelica,Radix Paeoniae Alba,Rhizoma Chuanxiong,and Rhizoma Corydalis.It was concluded that blood stasis was the direct cause of primary dysmenorrhea,many of which belonged to the deficiency of root (i.e.,deficiency of qi,blood and cold deficiency) and excess of branch.Chinese herbal medicine treatment should be focused on the regulation of both qi and blood,invigoration of both liver and kidney,as well as harmonization of the blood.
