Objective To investigate the evaluation significance of plasma D-dimer level for the prognosis in acute exacerbation of chronic obstructive pulmonary disease(AECOPD) excluding pulmonary embolism(PE).Methods The patients with AECOPD were collected from the respiration department and emergency internal medicine department of the Affiliated Hospital of Nantong University during 2007-2011.Thirty-five AECOPD cases of D-dimer positive and excluding PE and lower extremity deep venous thrombus(DVT)by CT angiography served as the experimental group and 35 cases of D-dimer negative as the control group.The differences in the first time hospitalization duration,GOLD grade,mortality rate,re-hospitalization times within 4 years,times of admission to ICU,times of intracheal intubation,rehospitalization and outside-hospital mortality rate were compared between the two groups.The receiver operatingcharacteristic(ROC)curve was applied to evaluate the short-term and long-term prognostic capacity of D-dimer.The t test at the follow up end point was used to analyze the D-dimer level in the death group and the survival group.Results The D-dimer level,length of hospital stay,death number of first time hospitalization,times of re-hospitalization,times of admission to ICU,times of intubation,re-hospitalization and outside-hospitalization mortality rate and total mortality rate had statistical differences between the experimental group and the control group(P＜0.05);but the differences in the age,gender and GOLD grade between the two groups had no statistical significance(P＞0.05).The sensitivity of D-dimer＞1 165 μg/L for predicting the death number of the first time hospitalization was 87.5 ％,and the specificity was 80.6 ％.The sensitivity of D-dimer＞ 865μg/L for predicting the mortality rate of re-hospitalization and outerside-hospital was 78.9 ％,and the specificity was 74.5 ％.The survival curve graph during the follow up period in the two groups revealed that the survival time and survival rate had statistical difference between the two groups.The D-dimer level in the death group was significantly higher than that in the survival group with statistical difference(P＜0.05).Conclusion The D-dimer level is an independent risk factor affecting the short-term and longterm prognosis of AECOPD.

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

BACKGROUND:Studies have shown that vacuum sealing drainage can accelerate wound healing through increasing the wound blood flow, but its influence on activated gelatinases in human chronic wound stil lacks corresponding research. OBJECTIVE:To observe the effect of vacuum sealing drainage on the activity of gelatinase during the healing of chronic wounds. METHODS:Total y 96 trauma patients admitted at the People’s Hospital of Hubei University of Medicine from April 2013 to January 2014 were divided into two groups:52 patients in chronic wound group were treated with vacuum sealing drainage and 44 in control group treated with wound drainage at 3 days after removal of breast cancer. In the chronic wound group, exudates from pressure sores and skin necrosis after removal of breast cancer were col ected as samples A and B;exudates from two cases of venous stasis ulcer were col ected as samples C and D;exudates from traumatic skin wounds col ected as sample E. RESULTS AND CONCLUSION:TLC analyzer showed that:after 15-day negative pressure therapy, activities of matrix metal oproteinase 2 in sample A with low activity of gelatinase, matrix metal oproteinase 9 in sample B, matrix metal oproteinase 2 and 9 in samples C, D, E were al increased significantly (P<0.05);however, the activities of matrix metal oproteinase 9 in sample A with high activity of gelatinases and matrix metal oproteinase 2 in sample B were reduced significantly after treatment (P<0.05). In addition, no significant difference was found in the activity of matrix metal oproteinase 2, matrix metal oproteinase 9 and activated gelatinase betweenthe chronic wound group and control group (P>0.05). These findings indicate that the variation of activated gelatinases activity in human chronic wounds may be the reason why the chronic wounds cannot be healed for a long time, but vacuum sealing drainage can regulate the activity of activated gelatinases in chronic wounds.

Objective To investigate the association between elevated levels of hsCRP and prognosis after stroke in Chinese patients.Methods Two hundred and ninety consecutive patients with firstonset stroke(197 ischemic and 93 hemorrhagic)and 290 age-and sex-matched control subjects without any cerebrovascular disease were studied.Plasma hsCRP level was measured and subsequent vascular events and death were determined in both groups over a 5-year period.Results Compared to control group,patients with stroke had higher plasma hsCRP level((3.3 ±3.8)vs(1.3±2.2)mg/L,t=8.048,P<0.01).Furthermore.within the group of patients with stroke,the mean plasma hsCRP level was higher in patients who experienced subsequent vascular events or death compared to patients without further complications ((4.4±4.3)vs(2.7±3.3)mg/L,t=3.496,P=0.001).Compared to the patients with lower hsCRP level(<1 mg/L),the relative risk for vascular events and death in stroke patients was 2.807(95%CI 1.544-5.495,P=0.001)in the hish hsCRP(>3 mg/L)patients.This increase of relative risk for vascular events and death in stroke patients persisted after the adjustment for age,sex and other cardiovascular risk factors such as hypertension and diabetes(OR 2.661,95%CI 1.323-5.352.P=0.006).Conclusions Patients presenting with stroke have higher levels of hsCRP compared to agematched controls.The degree of hsCRP elevation is correlated with the likelihood of subsequent VasCular events and death.These findings indicate that inerease of hsCRP level is associated with worsening prognosis after stroke in Chinese patients.

Gindenosides are the active ingredients of Panax ginseng. 20 (S) -protopanaxadiolocotillol type epimers are the main metabolites of 20 (S) -protopanaxadiol. The previous studies showed that there are stereoselectivity difference in pharmacodynamics and pharmacokinetics between 24R-epimer and 24S-epimer. The purpose of this study was to explore the excretion of the epimers in bile, feces and urine of rat. Liquid chromatography tandem mass spectrometry method has been performed for determination of 24R-epimer and 24S-epimer in bile, feces and urine. 24R-epimer or 24S-epimer was intragastric administered to rats at a single dose of 10 mg x kg(-1). Results showed that after administration the recovery of 24R-epimer and 24S-epimer in feces was 17.69% and 17.09%, respectively, while both of the two epimers were hardly detected in urine. The 48 h cumulative biliary excretion rate of 24R-epimer was 8.01% after administration, while only 1.47% for 24S-epimer. It indicated that there are stereoselectivity in biliary excretion of the epimers with intragastric administration.

Toxicogenomics (TGx) refers to a set of technologies that assess genome-wide responses after toxic agent exposure. Altered gene expression patterns that are caused by specific exposures reveal how toxicants may disrupt cellular processes and lead to side effects. Development and application of " omics" technology facilitate the toxicogenomic research which sharing and interpretation of the enormous amount of biological information generated in toxicologic field. In recent years TGx has been widely valued and successfully applied as an effective research tool to evaluate the toxic effects of traditional Chinese medicine (TCM). Here we reviewed current progress in the field of TGx and focused on its application in traditional Chinese medicine safety evaluation, especially in revealing the mechanism, finding potential toxic biomarkers and studying compatibility detoxification of TCM.

Objective To study DNA quantification and STR typing of samples pre-treated with pyrami-don. Methods The blood samples of ten unrelated individuals were anticoagulated in EDTA. The blood stains were made on the filter paper. The experimental groups were divided into six groups in accor-dance with the storage time, 30 min, 1 h, 3 h, 6 h, 12 h and 24 h after pre-treated with pyramidon. DNA was extracted by three methods: magnetic bead-based extraction, QIAcube DNA purification method and Chelex-100 method. The quantification of DNA was made by fluorescent quantitative PCR. STR typing was detected by PCR-STR fluorescent technology. Results In the same DNA extraction method, the sample DNA decreased gradually with times after pre-treatment with pyramidon. In the same storage time, the DNA quantification in different extraction methods had significant differences. Sixteen loci DNA typing were detected in 90.56% of samples. Conclusion Pyramidon pre-treatment could cause DNA degradation, but effective STR typing can be achieved within 24 h. The magnetic bead-based extrac-tion is the best method for STR profiling and DNA extraction.
