This article points out that the key of studying classics of Chinese medicine and Yijing is to precisely comprehend cultural information in these books. There are 3 key points about prehension and interpretation. The first one is correct identification and differentiation of specific cultural connotation as basic carrier of ancient cultural information,such as language,characters,symbols and figures. The second one is comprehensive understanding of the complex relationship among infiltrated cultural information of encyclopedia. The third one is accurate master of cultural information during the process of academic development.

Objective:To explore the expression of MMP-3 and extracellular matrix metalloproteinase inducer(EMMPRIN)in benign and malignant breast lesions and its relevance.Methods:Using immunohistochemical method,we examined the expression of MMP-3 and EMMPRIN proteins in 58 breast cancer specimens,28 premalignant lesions,40 hyperplasia specimens,40 benign tumor specimens and 20 normal breast tissues.The expression of MMP-3 mRNA and EMMPRIN mRNA was examined using in situ hybridization in 20 breast cancer specimens,20 premalignant lesions,20 hyperplasia specimens,20 benign tumor specimens and 20 normal breast tissues.The values of integral optic density(IOD)of the expression was calculated by image analysis system.Results:The expression of MMP-3 and EMMPRIN proteins and mRNA was stronger in breast cancer and premalignant lesions than in the other lesions.The IODs of MMP-3 and EMMPRIN proteins and mRNA in breast cancer and premalignant lesion were significantly higher than those of hyperplasia,benign tumors and normal breast tissues(P

Objective To explore the relationship between R time in thrombelastography (TEG) and prognosis of traumatic brain injury (TBI).Methods The data of TBI patients were collected in Fourth Peoples Hospital in Shaanxi Province from January 2015 to June 2016.The patients were divided into two groups according to the prolongation of R time at admission,and the basic data and the outcomes were analyzed.Results In basic data,Glasgow coma scale (GCS) [(9.7 ± 4.4) scores vs (12.1 ± 2.2) scores] was lower,and injury severity score (ISS) [(32.4 ± 8.9) scores vs (21.7 ± 10.4) scores],head abbreviated injury scale (AIS) [(5.0 ±0.0) scores vs (4.1 ± 1.5) scores],hemorrhage volume [(6.2 ± 5.5) ml vs (1.1 ± 1.8) ml] and mean arterial pressure[(127.2 ± 28.1) mmHg vs (103.3 ± 17.0) mmHg] were higher in the prolonged R time group.In outcomes,the in-hospital mortality (42.9％ vs 17.2％) and the rate of neurosurgical intervention (71.4％ vs 37.7％) were higher,and the duration of mechanically ventilated [(9.3 ±3.2) d vs (4.1 ± 1.7) d],ICU stay [(10.2 ± 4.4) d vs (5.6 ± 2.1) d] and hospital stay [(22.4 ± 8.1) d vs (8.3 ± 4.7) d] were longer in prolonged R time group.The Logistic regression analysis results showed that GCS ≤8 scores,ISS ＞ 25 scores and R time ＞ 10 min were the possible risk factors of hospital mortality.Conclusion TBI patients with longer R time have worse prognosis and longer R time is the possible risk factor of hospital mortality,and the prediction efficiency of R time need to be explored and validated by more research.

Iron uptake mechanism of Vibrio alginolyticus was primarily investigated. V.alginolyticus could survive in the medium with high-concentration iron chelator. The strain of V. alginolyticus isolated from diseased fish produced more siderophore than that from marine environment. The extract of siderophore from V. alginolyticus could stimulate the growth of Escherichia coli mutant AN93. Under iron limitation,the growth rate was decreased and several outer membrane proteins were induced. Adding iron into the iron-limited medium the normal growth could be recovered.

Objective To explore the value of 64-slice multi-detector computed tomography coronary angiography (64SCTA) in detecting the coronary artery plaque and to analyze the risk factors for unstable plaque. Methods A total of 112 inpatients who had been diagnosed as coronary artery disease by 64SCTA received catheter coronary angiography (CAG). The levels of serum endothelin-1 (ET-1), matrix metalloproteinase-9 (MMP-9), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and high-sensitivity C-reactive protein (hs-CRP) were measured. The effect of 64SCTA in detecting the coronary artery plaque was evaluated as compared with CAG. The patients were divided into the soft plaque group (n=51) and non-soft plaque group (n=61) according to the CT value of correctly detected plaque. The differences in the above detection indexes between two groups and the risk factors for soft plaque forming were analyzed. Results The 64SCTA had 87.4% sensitivity and 87.1% specificity in detecting coronary artery plaque, the positive predictive value was 82.2% and the negative predictive value was 91.0%. There were significant differences between soft plaque group and non-soft plaque group in the levels of MMP-9, IL-6, hs-CRP, the number of coronary lesions and the composition ratios of gender, diagnosis and diabetes. Logistic regression analysis showed that MMP-9>5.231 ng/L (P=0.0215, OR=2.33, 95%CI 1.13-4.79), hs-CRP>3.583 mg/L (P=0.0008, OR=4.32, 95%CI 1.84-10.15) and unstable angina pectoris (P=0. 0339, OR=4.33, 95% CI 1.12-16.77) were the risk factors for soft plaque formation. Conclusions 64SCTA has highervalue in detecting the coronary artery plaque, and is one of most reliable means in non-invasive methods. MMP-9, hs-CRP and unstable angina pectoris are independent risk factors of plaque instability.

Objective To investigate the clinical features,recanalization after medical treatment and clinical outcome of cerebral artery dissection.Methods We reviewed the clinical records of ischemic stroke patients with cerebral artery dissection who visited the First Affiliated Hospital of Zhejiang University between October 2010 and December 2013.We recorded patients' general information,neurological deficit,imaging and clinical treatment.We followed up the patients and statistically analyzed demographic data,recanalization and clinical outcome.Results Among 28 cases of cerebral artery dissection,carotid dissection was the most common (n =19,67.9％),followed by vertebral artery dissection (n =7,25.0％),while the combination of carotid and vertebral artery dissection was rare (n =2,7.1％).In the imaging of cerebral artery dissection,wire beads and occlusion were the most common signs (n =15,53.6％),followed by rat tail sign (n =7,25.0％),aneurysmal dilatation (n =4,14.3％) and dualchamber levy (n =2,7.1％).There were 18 cases of acute cerebral infarction in the 28 studied cases,but there was no significant difference between the degree of stenosis and cerebral infarction caused by cerebral artery dissection.All patients received standard antithrombotic therapy.The difference of the recanalization rate between using anti-platelet aggregation and anticoagulant therapy was not statistically significant (5/6 vs 9/13,P =0.37).Conclusions Although cerebral artery dissection is relatively rare clinically,the typical clinical manifestations of the disease and the characteristic imaging are helpful for the diagnosis.Standardization of antithrombotic treatment is still the first-line treatment of cerebral artery dissection.

Objective To investigate the difference between nodular gastritis and atrophy gastritis.Methods During 2004.4～2005.3, the clinical, endoscopic and pathological findings of nodular gastritis and atrophy gastritis were analysed.Results Nodular gastritis is usually classified as nodular type A(nodular gastritis) and type B(atrophic gastritis with nodular changes). The endoscopic appearance of nodular gastritis was characterized as uniform miliary pattern and predominantly affected young women. The incidence of dyspeptic symptom was higher in patients with nodular gastritis than in atrophy gastritis. Nodular gastritis in adults is caused by Helicobacter pylori infection. Antral biopsy specimens showed lymphoid follicle formation and/or marked lymphoid aggregates. The prevalence of lymphoid follicle formation in the antrum was higher in patients with nodular gastritis than atrophy gastritis. Moderate to severe atrophy gastritis also usually has the same nodular endoscopic appearance,but that is not uniform and intensive.Conclusion Nodular gastritis is a very special gastritis with Helicobacter pylori infection and is different from atrophy gastritis.It is worth to be noticed.
