This article has reviewed the invasion,prevention and cure situation and the latest research progresses of "bird flu"(flu carried by birds: found in Hong Kong in late 1997)with high pathogenicity on human beings in Hong Kong since 1997.By analyzing the invasive regularity of "bird flu"on human beings with the theory of traditional Chinese medicine,it was considered that H5N1 virus was attributed to the "fire" "smelly"poison,the epidemic poison got into the human body from the mouth,noses,and eyes.It attacked the lung first,and then got down to the stomach and intestine,direct attack of pericardium,consumption of body-fluid with wind symptom.It mainly attacked the children,youths and adults in crowd.Clinically,state of evil domination considered as sthenia-syndrome was the common disease type.The author studied out the modified Puerariae and Scutellariae and Coptidis Decoction as the main reference formula in treating "bird flu"with high pathogenicity on human beings and avians.

Objective To study the relationship between magnetic resonance imaging (MRI)of rheumatoid arthritis (RA)and traditional Chinese medicine (TCM)syndrome types.Methods 90 patients with RA were select-ed as the research subjects.Through 2 attended doctors more strict according to the specific diagnostic criteria of the syndrome,the implementation of the diagnosis of TCM syndromes.The conventional treatment of the patients were recorded,and the X line of the two hands joint was obtained by double blind reading.At the same time,the relevant symptoms and symptoms of the laboratory and other related information were analyzed.Results Of 90 RA patients, 22.22% patients were cold dampness stasis type,27.78% patients were damp heat blocking collaterals,26.67%patients were cold and heat syndromes,23.33% patients were deficiency of liver and kidney and phlegm stasis stasis type.Patients after the initial diagnosis,hands joint implementation hands joint side position was detected by MRI,the MRI results showed thickened synovium,bone erosion,bone marrow edema and joint effusion,and the constituent ratio of MRI images had significant difference (χ2 =13.372,P <0.05).Four TCM syndrome types of RA patients,after treatment,again implement hands joint anteroposterior and lateral radiographs of the MRI detection,after detection of radiology hands joint MRI detection results showed that implementation stage and detailed records,and at the time of initial diagnosis.The patients'hands joint MRI examination test showed that the control,any bone damage intensifies, the MRI signs of more serious progress.However,impaired bone level unchanged,MRI without aggravate was not changed.Conclusion For RA patients,MRI manifestations and TCM syndrome type has relationship.At early stage of the disease,active and reasonable use of anti -rheumatic drug treatment to improve the condition of RA can reduce the morbidity.

Objective To study the autonomic nervous regulation function,and to study relationship between heart rate variability and severity,organ dysfunction and prognosis in patients with systemic inflammatory response syndrome (SIRS).Methods All the patients were divided into two groups:SIRS and non-SIRS according to the criteria of SIRS. The SIRS group included 100 patients and the non-SIRS group 30 patients,and the control group included 30 heathy adults. SIRS group was further divided into two subgroups:survivor and succumbed.Heart rate variability(HRV)was analyzed with the two methods of time-domain and frequency-domain.Results The SIRS group had significantly higher APACHEll scores and MODS scores(P＜0.01)and lower HRV when compared with the non-SIRS group(P＜0.05).In the SIRS group,the succumbed groupallad statistically higher APACHEII and MODS scores and lower HRV than the survivor group( P＜0.01).There was a negative correlation between the prognosis of the patients and SDNN(r=-4.68,P＜0.01), SDNN＜55 ms was the most sensitive(76.2%),and specific(76.7%),with positive predictive value(90.4%)and negative predictive value(52.6%).Conlusion The SIRS patients had lower HRV,and there was a negative correlations with the severity of disease,organ dysfunction and prognosis.HRV(SDNN)were the useful index to evaluate the prognosis of critically ill patients.

Objective To investigate the power of the simplified acute physiology score Ⅲ ( SAPSⅢ) for prediction of outcome for patients with severe sepsis admitted to the intensive care unit ( ICU ). Methods A retrospective study was conducted. 677 severe sepsis patients with age ≥ 18 years old and the survival time in emergency ICU≥24 hours admitted to the emergency ICU of Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2008 to December 2011 were enrolled. The acute physiology and chronic health evaluationⅡ ( APACHEⅡ), sequential organ failure assessment ( SOFA ), SAPSⅡ, SAPSⅢ, and mortality in emergency department sepsis ( MEDS ) scores were recorded based on the poorest value within 24 hours of ICU admission. The 28-day result as denoted as survival or death was considered as the end point of the study. The ability to predict mortality by the score systems was assessed by using receiver operating characteristic ( ROC ) curve analysis and binary logistic regression models. Results Among the 677 patients with severe sepsis, 284 cases died within 28 days after admission, and the mortality rate was 41.9%. Compared with survivors, the patients in non-survival group was older with higher APACHEⅡ, SOFA, SAPSⅡ, SAPSⅢ, and MEDS scores and higher ratio of underlying diseases, such as primary hypertension and renal dysfunction, and they had more organ injury, higher ratio of lung infection and bacterial infection ( P < 0.05 or P < 0.01 ). It was identified by logistic regression that the APACHEⅡ, SOFA, SAPSⅡ, SAPSⅢand MEDS scores were significantly independent factors in 28-day death prediction in patients with severe sepsis ( all P=0.000 ). The rank of areas under the ROC curve ( AUC ) from high to low were MEDS ( 0.970 ), APACHEⅡ( 0.893 ), SAPSⅢ ( 0.875 ), SOFA ( 0.871 ), and SAPSⅡ ( 0.860 ), respectively. SAPSⅢ score and APACHEⅡ, SOFA, SAPSⅡscores were found to have an equivalent capacity in predicting the prognosis ( all P>0.05 ). The MEDS score in predicting the prognosis was obviously better than that of APACHEⅡ, SOFA, SAPSⅡ, and SAPSⅢscores ( all P<0.05 ). The MEDS score showed the best sensitivity ( 91.5%), and specificity ( 89.1%). The 28-day mortality in cases of MEDS≥11 was 85.8%. Conclusions ①For patients with severe sepsis who were admitted to ICU, MEDS was superior to APACHEⅡ, SOFA, SAPSⅡ, and SAPSⅢscores in predicting prognosis. MEDS≥11 may indicate a higher mortality rate.②SAPSⅢscore has comparable predictive capability with APACHEⅡ, SOFA and SAPSⅡscores may be recommended for prediction of the prognosis of patients with severe sepsis in ICU. But the SAPSⅢscore is unsuitable for predicting the prognosis of patients with acute sepsis in ICU options, and it is not superior to that of SAPSⅢscore in predicting prognosis of patients with sepsis in the emergency ICU than other score systems.

Objective To investigate the feasibility of SAPS 3-PIRO score for prediction of outcomes in severe sepsis patients in the intensive care units (ICU).The optimal scoring system was also evaluated in this study.Methods Data of 677 patients with sepsis,treated in ICU of the emergency department at the Beijing Chaoyang Hospital between January 2008 and December 2011,were analyzed.The inclusion criteria were:age ≥18 years and the diagnostic criteria of severe sepsis and organ damage recommended by the International Sepsis Definitions Conference in Washington DC,USA in 2001,as well as the criteria developed by the Conference as a reference.The patients,who did not meet the criteria were excluded from the study.Age,gender,underlying disease,main infection site,and duration of ventilator support of all cases were recorded.Vital signs,hematological findings (gases,biochemistry,coagulation) and causative pathogens and organ damage on day-1 in the ICU were also recorded.According to the data of the most unfavorable findings in the ICU on day-1,scores got from APACHE Ⅱ,SOFA (sequential organ failure assessment),SAPS Ⅲ(simplified acute physiological score Ⅲ),SAPS 3-PIRO (predisposition,infection,response,organ failure/dysfunction) and MEDS (mortality in emergency department sepsis score) scoring systems were calculated.All patients were followed up for 28 days.The outcome of survival and death at 28 days were the endpoints of this study.SPSS V13.0 (SPSS,Chicago,IL,USA) was used to analyze data.Continuous variables with normal distribution were expressed as mean ± standard deviation.The independentsample t test was applied when normality (and homogeneity of variance) assumptions were fulfilled otherwise the t' test would be used.The distribution of categorical variables in two groups was tested using the x2 test.Binary logistic regression models were also used according to the survival status.The values of scoring system in predicting outcomes and the determination of dividing value in predicting death were analyzed using receiver operating characteristic (ROC) curves.The area under the receiver operating characteristic (AUROC) curves was compared using Z test.P values less than 0.05 were considered statistically significant.Results The total 28-day mortality was 41.9％.APACHE Ⅱ,SOFA,SAPS Ⅲ,SAPS 3-PIRO and MEDS scoring systems were used to find the independent predictive factors of death within 28 hours in patients with severe sepsis.By using ROC curve and AUROC curve to compare the validity of these scoring systems,SAPS 3-PIRO score had comparable predictive capability in comparison with APACHE Ⅱ,SOFA and SAPS Ⅲ scores,and MEDS was superior to SAPS 3-PIRO,APACHE Ⅱ,SOFA and SAPS Ⅲ score.Conclusions For patients with severe sepsis admitted in ICU,MEDS was superior to SAPS 3-PIRO,APACHE Ⅱ,SOFA and SAPS Ⅲ score in predicting prognosis.MEDS has favorable capability in predicting death within 28 days.MEDS ≥ 11 was the sign of increased mortality.SAPS 3-PIRO score has comparable predictive capability in comparison with APACHE Ⅱ,SOFA and SAPS Ⅲ score and it may be suggested for clinical practice.

Objective To study the changes of vascular endothelial functional status and cytokine TNF-α in patients with multiple organ dysfunction syndrome (MODS).Methods Plasma levels of tissue plasminogen activator (t-Pa), plasminogen activator inhibitor-1 (PAI-1 ), circulating endothelial cell (CEC) and serum levels of endothelin (ET-1), tumor necrosis factor- ( (TNF-α), nitric oxide (NO) were determined serially dynamically in patients with MODS and those without MODS (non-MODS). At the same time Marshall scores were evaluated.Results Blood levels of TNF-α, ET-1, PAI-1, CEC, and Marshall scores were significantly higher in MODS and succumbed (those who died) groups than those in non-MODS and survied (those who lived) groups (P ＜ 0.05), but blood levels of NO and t-Pa were significantly lower ( P ＜ 0.05).Conclusion TNF-α played an important role in the progression of MODS. The increase of ET-1, PAI-1, CEC and the decrease of NO and t-Pa indicated endothelial dysfunction in MODS. Marshall scoring system for MODS was a sensitive parameter in evaluating the patients with MODS.

Objective To investigate the effect of hypertensive perfusion which induced by norepinephrine on the TNF-α and IL-6 in serum and the activity of Na~+-K~+-ATPase in lung tissue and to observe the morphology of lung tissue. Method Ten domestic pigs were suffered from ventricular fibrillation for 4 minutes and applied cardiopulmonary resuscitation. The pigs they were divided into two groups. Hypertensive perfusion group( n = 5) :the mean arterial pressure, which induced by norepinephrine was maintained as 130% as baseline for 4 hours; nor-real perfusion group( n = 5) : the mean arterial pressure was maintained as baseline for 4 hours, too. Hemodynamic parameters was observed, blood samples were extracted to detect the TNF-α and IL-6 in serum at the time of baseline, 10 min, 2 h and 4 h after successful resuscitation. The expression of Na~+ -K~+ -ATPase in lung tissue and the change of ultrastmeture and pathology in lung tissue was detected at 24 h. All values were analyzed by student' s t test. Results There was no influence on hemodynamic parameters except the blood pressure and heart rate in hypertensive perfusion group. The release of TNF-α and IL-6 were reduced(P < 0.01 ) and the activity of Na~+-K~+ -ATPase was upgraded in hypertensive perfusion group. Hypertensive perfusion could play a protective role on the morphology of alveolar cell. Conclusions Hypertensive perfusion which induced by norepinephrine could reduce the release of inflammatory cytokines, upgrade the activity of the Na~+-K~+-ATPase, decrease the consumption of surfactant and have an important protective effect on lung tissue.

ObjectiveThe difference of Cys-C ( serum cysteine proteinase inhibitor C) among sepsis group,systemic inflammatory response syndrome (SIRS) group,and non -SIRS group were explored in this study.The significance of mortality and the relationship between Cys-C and acute physiology and chronic health evaluation (APACHE)Ⅱ score were under discussed. Methods After excluding the individual whose survival less than 24 hours,two hundred and fifty patients sought medical care in the emergency department of Beijing Chaoyang Hospital of the Capital Medical University were selected as samples from October 2008 to October 2009.They were classified into three groups:SIRS group ( n =121 ),non-SIRS group (n =74) and sepsis group ( n =55 ).The serum Cys-C level and APACHE Ⅱ score were determined for each patient.The positive detection rate of Cys-C ( ＞ 830 ng/ml) was calculated and then a 28-day mortality was recorded according to this study result.The positive detection rate and 28-day mortality were also compared with chi-square test.The prognostic values of Cys-C,APACHE Ⅱ score for the 28-daymortality were evaluated by logistic regression analysis.Results There was significant change observed between sepsis group and non-SIRS group (41.38％ vs. 13.57％,P =0.007 ) for the positive detection rate of Cys-C,as well as that between SIRS group and non-SIRS group ( 32.79％ vs. 13.57％,P =0.005).However,a contrary result was obtained when compared sepsis group with SIRS group (41.38％ vs.32.79％,P =0.346) ).Significant difference was noticed in the 28-day mortality of the patients from sepsis group and SIRS group in comparison to those of non-SIRS group (41.6％ vs. 17.2％,P ＜ 0.01 ;36.91％ vs. 17.2％,P ＜ 0.05).Cys-C level in patient with sepsis indicated a positive correlation to APACHE Ⅱ score ( P ＜0.0001 ).ConclusionsThe positive rate of Cys-C in SIRS group and septic group were significantly higher than that of non-SIRS patients,and this is an index for poor prognosis in sepsis patients.

Objective To compare the point-of-care testing (POCT) and laboratory testing of myocardial damage markers in the diagnosis and prognosis of acute coronary syndrome (ACS).Methods A total of 3467 patients with ACS who were treated in the Emergency Department Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 1,2006 and June 30,2010 were retrospectively reviewed.The patient demographics (age,sex,past medical history and smoking history) and laboratory testing results (myocardial damage markers,D-dimer,NTproBNP,and ejection fraction [EF]) were analyzed.The patients who received POCT or laboratory testing of myocardial damage markers were compared with regard to emergency department stay (i.e.,the time from the emergency visit to interventional or conservative treatment),cardiovascular events during hospitalization (congestive heart failure,ventricular fibrillation,and cerebrovascular disease),and 28-day mortality rate.Results The emergency department stay,incidence of a cardiovascular event,and 28-day mortality in the POCT group were all lower than that in the laboratory testing group (P =0.000).A prolonged emergency department stay result in an increased incidence of 28-day mortality.The higher level of D-dimer and decreased EF prompted an increased incidence of 28-day mortality.Conclusions Compared with conventional laboratory testing,POCT can significantly shorten the length of an emergency department stay for an ACS patient,decrease the incidence of a cardiovascular event,and improve the prognosis.

The expressions of survivin,PcNA and Bcl xl were detected in 68 patients with pramary hepatic careinoma(HCC) and adjacent tissues and 12 cases of normal hepatic tissues by immunohistochemical (IHC) EnVision and Tunel method.The relationship between survivin gene expression and apoptosis index(AI),proliferation index(PI) and apoptosis inhibition factors were studied.The positive rate of survivin and Bcl xl expression were 58.8%(40/86) and 48.5%(33/68) in HCC,5.88%(4/68) and 36.8%(25/68) in adjacent tissues,0 (0/12) and 25%(3/12) in normal hepatic tissues.The expression of Survivin and Bcl xl are mainly in cell membrane and cytoplasm.Survivin expression is related to metastasis of HCC ( P
