Pulmonary fibrosis is a group of chronic lung diseases induced by various causes. Because of its complex etiology and pathogenesis,most of the pulmonary fibrosis diseases have no effective treatment currently and the quality of life and prognosis of patients are poor. Recent studies on biomarkers of susceptibility and effect associated with pulmonary fibrosis have made great progress, which is of great significance for screening and early diagnosis of the disease,and even for the evaluation of therapeutic efficacy and prognosis. This paper reviews some potential biomarkers of pulmonary fibrosis diseases,including the mucin 5B promoter variant and matrix metalloprotease-7 associated with idiopathic pulmonary fibrosis,heme oxygenase-1 and serum Se related to silicosis,Krebs von den Lungen-6,surfactant proteins-D and sphingolipids signaling associated with various pulmonary fibrosis, in order to provide new ideas for further research on the prevention and treatment of pulmonary fibrosis diseases.

Objective To evaluate the preoperative CT scanning in cardiac carcinoma.Methods 52 cases of cardiac carcinoma proved by operation and pathology were analysed.Results By CT scanning,the size of the tumor,it′s local extension and relation to the adjacent structures and lymph node metastases could be demonstrated.Conclusion CT scanning plays important role in the operability of the cardiac carcinoma and the planning of treatment.

Objective: To explore the correlation among plasma level of brain natriuretic peptide (BNP), serum D-dimer level and patient's status in patients with acute pulmonary embolism (APE).Methods: A total of 122 APE patients who were hospitalized from Mar 2012 to Dec 2015 were selected.According to right heart function and clinical symptoms, patients were divided into low risk group (n=61), medium risk group (n=36) and high risk group (n=25);after discharge, all patients were followed up for six months, then according to survival or not, they were divided into survival group (n=105) and death group (n=17).Plasma BNP and serum D-dimer levels were measured and compared among all groups, then correlation among BNP, D-dimer levels and severity of patient's status was analyzed.Results: Compared with low risk group, there were significant rise in levels of plasma BNP [(133.28±74.92)ng/L vs.(273.89±179.29)ng/L vs.(834.80±509.09)ng/L] and serum D-dimer [(761.80±333.65)ng/ml vs.(966.67±370.33)ng/ml vs.(1228.40±569.11)ng/ml] in medium risk group and high risk group, and those of high risk group were significantly higher than that of medium risk group, P<0.01 all.Compared with survival group, there were significant rise in levels of plasma BNP [(257.33±27.11)ng/L vs.(696.47±64.92)ng/L] and serum D-dimer [(818.57±64.92)ng/ml vs.(1513.25±48.14)ng/ml] in death group, P<0.01 all.Pearson correlation analysis indicated that plasma BNP, serum D-dimer levels were significant positively correlated with severity of patient's status (r=0.69, 0.41, P<0.01 both), and plasma BNP level was significant positively correlated with serum D-dimer level (r=0.79, P=0.002).Conclusion: Measurements of plasma BNP and serum D-dimer in APE patients are help to assess severity of patient's status and short-term prognosis, and provide basis for clinical individualized therapy.

Objective To analyze the risk factors of pulmonary embolism in patients with negative Ddimer in serum in order to determine the need of pulmonary computed tomography angiograph (CTA) to confirm the final diagnosis in those patients for avoidance of misdiagnosis.Methods A retrospective analysis of 106 patients suspected to suffer from pulmonary embolism (PE) with serum negative D-dimer checked with pulmonary CTA was carried out.According to the results of CTA, the patients were divided into two groups, namely PE group (n =41) and non-PE group (n =65).The difference in clinic presentation, the time elapsed from onset to visit, N-terminal pro-brain natriuretic peptide (NT-proBNP), high risk factors (such as immobilization for 3 weeks, leg swelling and pain to palpation, history of deep vein thrombosis, malignancy) and Wells score (≥ 4 points indicates probability of PE).And logistic regression analysis was made to investigate the risk factors in PE with negative D-dimer.Results The analysis study showed that 38.6％ of total patients suspected to suffer from PE with serum negative D-dimer were checked by CTA to confirm the presence of PE.One important characteristics of the D-dimer negative PE patients was the longer time consumed from onset to visit [(9.51 ±2.01) d vs.(4.01 ±1.92) d, P＜ 0.05], and majority of the CTA positive patients suspected to suffer from PE with negative D-dimer had high risks of PE (P ＜0.01).Compared with the non-PE group, the Wells score ≥4 points and the level of serum NT-proBNP significantly increased in the PE group (P ＜ 0.01).Logistic regression analysis revealed that dyspnea, high NT-proBNP level and Wells sore ≥ 4 points were risk factors for D-dimer negative PE.Conclusion Delayed treatment was the main cause of misdiagnosis of D-dimer negative PE.Dyspnea, high NT-proBNP level and Wells sore ≥4 points were risk factors for suspected PE patients with negative D-dimer, and these patients should be confirmed by pulmonary CTA.On the contrary, PE could be excluded if patients with D-dimer negative had no these risk factors.

OBJECTIVE: To optimize the prescription of traditional Chinese medicine for motion sickness (MS).METHODS: Zingiber officinale,Herba pogostemonis,Aucklandia lappa were extracted respectively,and rotating-inducing MS mice were enrolled in uniform design.The prescription was optimized with MS index as the parameters.RESULTS: The optimal prescription was as follows:60 g Z.officinale,45 g Herba pogostemonis,5 g A.lappa.The extractive of prescription was significantly better than dimenhydrinate in the treatment of MS.CONCLUSION: MS index is a stable and sensitive parameters and it is suitable for screening and evaluation of anti-MS drugs.R.zingiberis,H.pogostemonis,A.lappq are potential drug for MS.

AIM: To study the protective effect and mechanism of panax notoginseng saponinsa(PNS) for dealing with rats with middle cerebral artery ischemia reperfusion(CI/RP). METHODS: To establish the rat middle cerebral artery ischemia/reperfusion model with suture occlusion technique and record the neurologic impairment evaluation score on the basis of Zea Longa method,measured the infarct volume,and the others were detected neuron apoptosis by TUNEL technology and endogenous brain-derived neurotropic factor(BDNF) expression by immunohistochemistry technology. RESULTS: The administration of PNS to rat decreased neurologic impairment,reduced infarct volume,inhibited the neuron apoptosis,and increased endogenous BDNF expression after 24 hours CI/RP. CONCLUSION: Increasing endogenous BDNF expression after CI/RP might be the mechanisms of PNS for achieving neuroprotections.
