OBJECTIVEMeasures of ventilation-CO₂output relationship have been shown to be more prognostic than peak O₂uptake in assessing life expectancy in patients with chronic heart failure (CHF). Because both the ratios (VE/Vco₂) and slopes (VE-vs-Vco₂) of ventilation-co₂ output of differing durations can be used, we aim to ascertain which measurements best predicted CHF life expectancy.

METHODSTwo hundred and seventy-one CHF patients with NYHA class II-IV underwent incremental cardiopulmonary exercise testing (CPET) and were followed-up for a median duration of 479 days. Four different linear regression VE-vs- Vco₂ slopes were calculated from warm-up exercise onset to: 180 s, anaerobic threshold (AT), ventilatory compensation point (VCP); and peak exercise. Five VE/Vco₂ ratios were calculated for the following durations: rest (120 s), warm-up (30 s), AT (60 s), lowest value (90 s), and peak exercise (30 s). Death or heart transplant were considered end-points. Multiple statistical analyses were performed.

RESULTSCHF patients had high lowest VE/Vco₂ (41.0 ± 9.2, 141 ± 30%pred), high VE/Vco₂ at AT (42.5 ± 10.4, 145 ± 35%pred), and high VE-vs-Vco₂ slope to VCP (37.6 ± 12.1, 126 ± 41%pred). The best predictor of death was a higher lowest VE/Vco₂ (≥ 42, ≥ 141%pred), whereas the VE-vs-Vco₂slope to VCP was less variable than other slopes. For death prognosis in 6 months, %pred values were superior: for longer times, absolute values were superior.

CONCLUSIONThe increased lowest VE/Vco₂ ratio easily identifiable and simply measured during exercise, is the best measurement to assess the ventilation-co₂output relationship in prognosticating death in CHF patients.

OBJECTIVESince 2011 EB-APS conference, we hypotheses that phase switching of inspiration-expiration is dominantly initiated by oscillatory information PaO2, PaCO2 and [H+] via fast peripheral chemical receptors. However, the evidence of the waveform of ABG is lack.

METHODSSix surgery patients with normal heart function and negative Allen test, had been placed the arterial catheterization directly connected to 3 x 1 000 mm pre-heparin plastic pipe for continuous collecting arterial blood. We counted the number of heart beat for the blood collecting time, and separated the blood pipe into the heart beat numbers' short pieces using haemostatic forceps, then put pipe into iced water at once fir analyzing PaO2, PaCO2, pH and SaO2 as soon as possible. We selected two breaths cycles of waveform from each patient for data calculations of magnitudes and time interval.

RESULTSThe heart beat numbers for filling blood into pipe were 16 ± 2, and all covered more than 2 breathing cycles. Each breathing cycle is cover 5 ± 0.6 heart beat. There were significant changes of PaO2, PaCO2, [H+] a and SaO2 (i.e. the highest high values compare to the next lowest values, P < 0.05). The time interval of changing PaO2, PaCO2, [H+]a and SaO2 magnitudes were 11.28 ± 1.13 mmHg, 1.77 ± 0.89 mmHg, 1.14 ± 0.35 nmol/L and 0.52% ± 0.44% respectively.

CONCLUSIONThis simple continuous beat-by-beat arterial blood sampling and ABG analyzing method is new and practicable. We obtain a clear evidence of periodic parameters ABG waveform, which following breathing cycle.

Objective To describe and analyze the characteristics and trend of liver cancer,through data gathered from the Cancer Registry System,in China.Methods Annual registration data on cancer incidents and deaths of 2003-2007,from 32 cancer registries were employed.Crude rates of incidence and mortality,and age-standardized rates by the China population (ASRc) and the world population (ASRw) were calculated.Incidence and mortality rates by age,gender,and by area (urban or rural) were analyzed,and comparison was made internationally,based upon data from the GLOBOCAN 2008.Results The total person-years of 2003-2007 observed from the 32 cancer registries were 255 430 909,in which 197 651 428 from the urban areas,and 57 779 481 from the rural areas.A total of 68 146 incident cases with liver cancer were reported,which accounted for 10.03％(ranked second) of all the registered cases with cancers,with the average annual incidence as 26.68per 100 000 (39.42 in males,13.63 in females).ASRc and ASRw were 13.29 per 100 000 and 17.45per 100 000,respectively.Sex ratios for incidence and mortality were 2.89:1 and 2.72:1,respectively.Incidence rates were 23.91 per 100 000 in urban areas,and 36.15 per 100 000 in rural areas.For mortality rates,they were 22.39 per 100 000 m urban areas and 34.05 per 100 000 in rural areas,respectively.Relative greater differences could be seen amongst these registries.The incidence rates were 10.15-33.85 per 100 000 in the urban areas,and 11.83-78.59 per 100 000 in the rural areas.For mortality rates,they were 13.99-28.45 per 100 000 in urban areas,and 11.02-71.99 per 100 000 in rural areas.According to data from the 184 cancer registries through GLOBOCAN 2008,liver cancer incidence in China was ranked the 5th in males,and 6th in females while mortality was ranked 2nd in males,and 5th in females.Conclusion Liver cancer had been the second most leading malignancy,following lung cancer,with annual incidents and death cases around 360 000 and 350 000,respectively and the figures seemed to be increasing.Nationwide monitoring and research programs on liver cancer should be emphasized.

OBJECTIVETo investigate the high risk factors related to acute respiratory distress syndrome(ARDS) following serious thoracoabdominal injuries.

METHODSThe clinical data of 282 patients with serious thoracoabdominal injuries were retrospectively studied. Univariate and Cox multivariate regression analysis were used to determine the risk factors related to ARDS following serious thoracoabdominal injuries.

RESULTSThe incidence of ARDS was 31.9% (90/282) in patients with serious thoracoabdominal injuries. The mortality caused by ARDS was 37.8% (34/90). The univariate analysis and multivariate analysis demonstrated that the clinical conditions such as elder age, shock, dyspnea, abnormal arterial blood gas, hemopneumothorax, pulmonary contusion, flail chest, coexisting pulmonary diseases, multiple abdominal injury and high ISS score were the independent high risk factors related to ARDS.

CONCLUSIONThere are many high risk factors related to ARDS following severe thoracoabdominal injuries, which should be detected early and treated timely to decrease the incidence and mortality of A RDS.

Objective To validate the four chronic kidney disease epidemiology collaboration (CKD-EPI) predictive equations based on serum creatinine (SCr) and cystatin C (Cys C) in Chinese CKD patients,and try to develop the GFR predictive equations for Chinese CKD patients.Methods254 CKD patients were randomly selected from four Grade ⅢA hospitals in different regions in China from September 2007 to December 2010.Clearance of dual plasma sampling 99mTc-DTPA was used to measure glomerular filtration rate (rGFR) in 254 CKD patients.The serum concentration of Cr and Cys C were measured.CKD-EPI SCr equation,Cys C equation,Cys C equation adjusted for age,sex and race,SCr/Cys C combinated equation adjusted for age,sex and race were used to estimate GRF ( labeled as eGFR1,eGFR2,eGFR3 and eGFR4,respectively).The correlation,bias and precision of eGFRs were compared with rGFR by Wilcoxon signed rank test,intraclass correlation coefficient (ICC) and Spearman correlation analysis.The deviation degree between rGFR and different eGFRs was compared via Bland-Altman graph.The accuracy within 15％,25％,30％ ( P15,P25,P30) and the staging correctness of eGFR against CKD at different stages was calculated.ResultsThe rGFR in 254 CKD participants was [ 48.07 (26.19 -92.97 )] ml · min -1·(1.73 m2) -1.The Spearman correlatiou coefficients (CC) of eGFR and rGFR varied within the range of 0.873 - 0.896 ( P =0.000 ).The intra-class CC ( ICC ) varied within the range of 0.920 - 0.942.The correlation of eGFR4 was the best.The absolute deviations of 4 eGFRs and deviation precision were eGFR4 ＜eGFR3 ＜ eGFR2 ＜ eGFR1.The 95％ confidence intervals for the regression line of 4 eGFRs shown by Bland-Altman graphs were 92.5,87.3,83.0 and 76.1 ml · min-1 · ( 1.73 m2 ) -1,respectively,with the best result of eGFR4.For P30,the correctness of 4 eGFRs were eGFR4 ＞ eGFR3 ＞ eGFR2 ＞ eGFR1,but no significant difference was found by Chi square test (x2 =6.448,P =0.092).The overall correctness rate in 4 eGFRs against CKD stages were 48.4％ -57.5％,with the highest consistency of eGFR4,but their staging correctnessratewerenotideal(Kappa values were 0.405,0.348,0.366 and 0.463,respectively).Conclusions Compared with CKD-EPI SCr equation,no advantage was found in CKD-EPI Cys C equation.The Cys C equation adjusted by age and sex shows a little advantages over CKD-EPI Cys C equation in bias,precision,correlation and accuracy.The CKD-EPI SCr/Cys C combinated equation adjusted by age,sex and race has advantage over other three equations not only in bias,precision,correlation and accuracy,but also in staging correctness.However,the validation of this equation is still not fairly ideal for Chinese CKD patients.Based on these findings,it is essential for the Chinese CKD patients to develop SCr/Cys C combined predictive equation which adjusted by age,sex or other factors.(Chin J Lab Med,2012,35:798-804)

BACKGROUNDWhite blood cell count is an important index to the outcome of patients. In hospital, leukopenia is accompanied by high mortality, morbidity and treatment costs. However, in infectious diseases, the reasons responsible for leucopenia was not well elucidated. We investigated patients with gastrointestinal fistula to find risk factors for leukopenia.

METHODSA prospective case control investigation was carried out in the Gastrointestinal Fistula Center, General Surgical Institute of Jinling Hospital. Cases included gastrointestinal fistula patients with leukopenia (n = 98) and controls composed of gastrointestinal fistula patients with normal white blood cell count (n = 78). The two groups were compared for risk factors of leucopenia by statistical analysis.

RESULTSFactors associated with an increased risk for leukopenia included bacterial infection (25.5%) and hypoalbuminaemia (61.2%). Multivariable Logistic regression analysis identified bacterial infection (80%), urinary catheter (70%) and central vein catheter (60%) as the independent determinants for mortality in cases.

CONCLUSIONSIn patients with gastrointestinal fistula, two independent factors for leukopenia and three significant predictors of mortality were elucidated. We suggest that clinicians give patients more supportive management and apply prevention strategies to treat and prevent leukopenia.

Echinococcus granulosus is an important zoonotic parasite globally causing cystic echinococcosis (CE) in humans and animals. In this study, prevalence of CE and variation of cox1 gene sequence were analyzed with isolates E. granulosus collected from different areas in northern Xinjiang, China. The survey showed that 3.5% of sheep and 4.1% of cattle were infected with CE. Fragment of cox1 was amplified from all the positive sheep and cattle samples by PCR. In addition, 26 positive samples across the 4 areas were included. The isolates were all E. granulosus sensu stricto (s.s.) containing 15 haplotypes (Hap1-15), and clustered into 2 genotypes, G1 (90.1%, 91/101) and G3 (9.9%, 10/101). Hap1 was the most common haplotype (48.5%, 49/101). Hap9 were found in humans samples, indicating that sheep and cattle reservoir human CE. It is indicate that E. granulosus may impact on control of CE in livestock and humans in the region.

OBJECTIVETo investigate the rational digestive reconstruction after total gastrectomy for gastric malignancy.

METHODSThree types of digestive reconstruction were performed after total gastrectomy in 189 cases with gastric carcinoma. The operating time, morbidity and mortality, food intake, digestive tract symptoms, nutritional status at 1 and 3 years after surgery and 1-, 3-, 5-year cumulative survival were compared.

RESULTSThere were no significant differences among the three procedures in operative morbidity and mortality, postoperative food intake, nutritional status (Hemoglobin, total protein and labium), and incidences of diarrhea and dumping syndrome (P > 0.05). The overall 1-, 3-, 5-year survival rates were 75.3%, 38.2% and 20.5% respectively, and there were no significant differences among the three groups (P > 0.05). Orr-type and P-type esophagojejunostomy had an advantage of anti-esophageal reflux, and were obviously superior to Moynihan-type anastomosis (P< 0.01). Compared with P-type reconstruction, Orr-type reconstruction was simpler with shorter operating time, and less complications.

CONCLUSIONSOrr-type Roux-en-Y esophagojejunostomy can be recommended as an adaptable method of digestive reconstruction after total gastrectomy for gastric cancer because of its avoiding reflux esophagitis, maintaining better nutritional status and quality of life, and simpler procedure.
