Objective To study the inlfuence factors on detection of activity of four coagulation factors in prothrombin complex concentrates (PCC) by several factors. Methods Using Pharmacopoeia of the People’s Republic of China (2010) as reference, the activity of four coagulation factors in PCC were investigated by choosing different pre-treatments, different diluents, different salt concentration, different standard human plasma and different company reagents. Results The activity of FII, FVII, FX were decreased and FIX was increased in the condition of adding protamine sulfate, and there were no differences of four coagulation factors whether warm bath in 37 for 15 min or not. However, the differences of four coagulation factors were significant by using deficient plasma, saline, distilled water and commercial dilution buffer(P<0.05). The activity of coagulation factor II, X in 1 mol/L salt concentration of PCC were significantly lower than in 0.25 mol/L(P<0.05), while coagulation factor VII, IX were not. The activity of FII, FVII, FIX, and FX were different by using different standard human plasma to make standard curve. The activity of four coagulation factors existed significant difference(P=0.00) by using SIEMENS company reagents and domestic reagents. Conclusion Choosing different pre-treatments, different dilution buffers, salt concentration, standard human plasma and commercial kits will inlfuence the detection result of coagulation factors.

Objective:To discuss what impact prone position ventilation (PPV) plays in treatment of acute respiratory distress syndrom (ARDS)originating from pulmonary disease(ARDSp) and extra-pulmonary disease(ARDSexp).Methods: Retrospective case-control cohorts study. Sixty patients with ARDS were included, were classified two groups which were originated from pulmonary disease(n=30) and extra-pulmonary disease(n=30), they were ventilated in PPV. And oxygenation of 0,2,4, and 6 hours in PPV, static compliance(Cst), airway resistance(Raw) of were evaluated. The Ultrasonic Cardiac Output Monitor was applied to monitor the cardiac function.Results:At 2 hours after ventilation in ARDSexp group, PaO2/FiO2 have been improved significantly. The longer duration of PPV seemed to be associated with continuous improvement and peaks at 4 hours. In ARDSexp group PaO2/FiO2 after ventilation at 3 hours exceeds the other groups. At 4 hours after ventilation, PaO2/FiO2 of both ARDSp and ARDSexp groups of PPV have been improved than that of supine position. After ventilation for 4 hours, the RAW of ARDSp decreases dramatically and considerably below the other groups.Conclusion: PPV was a safe and effective maneuver for improving oxygenation in patients with ARDSp and ARDSexp. Both ARDSp and ARDSexp clearly appear to benefit from PPV, particularly in ARDSexp group. PPV aslo influenced haemodynamics in patients rarely.

Objective To study the clinical effect of minimally invasive percutaneous nephrolithotomy in patients with diabetes mellitus and non-diabetic patients. Methods A retrospective analysis was performed to look into the clinical data of 2,796 patients undergoing downward F18minimally invasive percutaneous nephrolithotomy during May 2007 to June 2016 under X-ray guidance Among them,582 diabetic patients were assigned as the diatetes group,aged 26-82 years,279 male,303 female, 174 with pelvic stones,255 with multiple calculi,153 with staghorn calculi,fasting blood glucose 5.4~20.3 mmol/L,postprandial and 2 hours blood glucose 9.1~28.9 mmol/L. In the group,the results of preoperative fasting blood glucose,glycosylated hemoglobin,meal 2 hours blood glucose,diabetes mellitus immune and two others,were in line with diabetes diagnosis and typing standard, and the stones were tested by infrared spectrum analyzer for determination of chemical composition(P<0.05). The rest 2,214 diabetic patients were set as non-diabetic group. The two groups were compared in terms of the operation duration,the rate of stone removal,surgical complications and hospital stay. Results There were no significant differenices in the operation duration,rate of stone removal and operative complications between the two groups(P>0.05),but the hospital stay in the diabetic group was significantly longer than that of the control group. In comparison of the stone compositions,therate of uric acid stones in the diabetic group was significantly higher than that of the control group (P < 0.05). Conclusion Minimally invasive percutaneous nephrolithotomy is safe and effective for the treatment of renal calculi in patients with diabetes mellitus. Diabetic patients are susceptive to uric acid stones and those patients at the poor control of blood glucose suffer from a higher recurrence of renal stones , which reminds the importance of doctors to educate the patients on the prevention of kidney stones.

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.

In this study, in vitro chemosensitivity testing was conducted on primary cultured breast cancer cells from 96 patients with breast cancer, and the results showed that the cells from a few patients with primary breast cancer developed multidrug resistance (MDR) prior to the first chemotherapy exposure. All the cells from the recurrent cancer patients had MDR. The findings suggested that patients having MDR would benefit from high-dose chemotherapy (HDC) regimens. In vitro chemosensitivity screening, which was aimed at improving the therapeutic efficacy and minimizing side effects, helps in choosing individualized treatment for breast cancer.

Objective To derive reference limits of cardiac functional parameters (CFP) determined by gated myocardial SPECT imaging, and to analyze the influence of gender, age and weight on CFP. Methods One hundred and seventy-five consecutive outpatients (89 males with age of (48.3±10.7) years and 86 females with age of (49.8±10.4) years) were defined as patients with low-likelihood coronary heart disease (LCHD). All patients underwent adenosine or exercise stress 99Tcm-MIBI G-MPI from February 2008 to April 2011. The EF, EDV and ESV of the left ventricle were measured by quantitative gated SPECT (QGS) software. The reference limits were derived by means of Gaussian distribution or percentiles. The influence of gender, age and weight on CFP was analyzed by multiple regressions for linear models. Two-sample t test was used to analyze data of 2 groups. Parameters between different age groups were compared by one-way analysis of variance. Results The lower reference limit of EF for males was 50%, the upper limit of EDV and ESV was 112 ml and 49 ml respectively. For females, the corresponding reference limits were 54%, 77 ml and 30 ml. Men had higher EDV, ESV (EDV: (75.8±18.3) ml vs (53.3±11.7) ml, t=9.35, P<001; ESV: (27.1±10.9) ml vs (14.3±7.9) ml, t=8.59, P<0.01) and lower EF than women ((65.1±76)% vs (74.7±10.0)%, t=-6.92, P<0.01). The incidence of small hearts in women was 76%(65/86). The gender and age was the primary and secondary predictors of both of EF and ESV, while the body weight was a significantly third predictor for cardiac volume. Patients were dived into different age (≤40 years, 41-49 years, ≥50 years) groups. For males, EDV, ESV and EF were not significantly different among the different age groups (F values: 1.106, 0.954, 1.029, all P>0.05). For females, EDV was not different (F=2408, P>005), while ESV and EF were significantly different among 3 groups (F values: 5.010, 6.229, both P<0.05). Conclusions The CFP determined by G-MPI in LCHD patients are significantly affected by gender and age. The age-related changes of CFP in males are different from those in females.
