Objective To explore a quick and feasible method of screening malaria parasite by using a Sysmex XE-2100 hematology analyzer though alarm information on high eosinophil count and atypical eosinophil distributions in the WBC scattergram. Methods Sysmex XE-2100 hematology analyzer was used for complete blood cell analysis. Microscopic review was used when high eosinophil count and atypicaleosinophil distributions in the WBC scattergram were found. If the review showed normal eosinophil cells, wecontinued to focus on red cell for searching malaria parasite. Results Among 1 501 specimens showing higheosinophil counts and atypical eosinophil distributions, nine cases with normal eosinophil cells were indisaccordance with the hematology analyzer, six of them showed high eosinophil count in the Sysmex XE-2100 hematology analyzer, whose distribution was located close to neutrophil clusters in scattergram. The otherthree had an abnormal WBC scattergram. There was no gap between eosinophil clusters and neutrophilclusters, which brought no classified results. But all the nine specimens had been found the trophozoite,schizont and merozoite in blood smears. Conclusions There were great possibility of the existence of themalaria parasite in specimens when hematology analysis showed high eosinophil count and atypical eosinophildistributions in the WBC scattergram in a Sysmex XE-2100 hematology analyzer, although these alarm wasnot comfirmed by microscopic review. This method provides not only a simple and reliable way for quickscreening malaria parasite but also has a great value in preventing the undetected ratio on malaria parasite.

Objective To construct and evaluate a nomogram for predicting the risk of peri-operative complications after radical retro-pubic prostatectomy (RRP) with standard classification criteria.Methods The peri-operative complications and clinicopathological data of 240 patients (50-82 years old) who had undergone RRP for prostate cancer from June 2006 to June 2011 were retrospectively collected.Gleason score:95 cases < 7; 145 patients ≥ 7;Clinical staging:cT1 is 1 case (0.4%),T2a 5 cases (2.1%),T2b 7 cases (2.9%),T2c 162 cases (67.5%),T3a 26 cases (10.8%),T3b 39 cases (16.3%).The peri-operative complications (in 30 days after surgery) were classified by Clavien-Dindo Classification system (the occurrence rates are as follows:rectum injury 1.6%,wound infection 2.0%,deep venous thrombosis 1.2%,urinary leak 5.0%,lymphocele 4.5%,myocardial infarction 5.8%,second look operation 1.6%),and a logistic regression model was used to construct the nomogram.Results BMI,N staging and Blood loss more than 200ml during surgery were independent prognostic factors of RRP morbidity in multivariate logistic regression.The nomogram predicting the risk of peri-operative complications showed relative good concordance index (0.633) and good calibration. Conclusions Based on the clinicopathological factors,a nomogram to predict the probability of peri-operative complications in patients undergone RRP was constructed.This statistical tool may be beneficial in judging operation risk and help consulting with patient before or after surgery.

Objective To compare the toxicity and anti-inflammatory effect of total saponins from Panax japonicus by different extraction technology. Methods The total saponins of sample 1, sample 2, sample 3, sample 4, sample 5 and sample 6 was prepared respectively by different process, and RAW264.7 cells were treated with the samples of different concentration. Then cells morphology was observed under microscope, thiazolyl blue (MTT) method was used to detect cell activity, the nitric oxide (NO) release of RAW264.7 cells was detected with NO kit. Results The cell toxicity of different samples from low to high was as follows:sample 4

Background and purpose:Bladder cancer radical surgery is dififcult with many perioperative complications, and the learning curve is long. To introduce the clinical application of complete retrograde radical cystectomy and consequent abdominal cavity reconstruction in male bladder cancer, and to provide a standardized surgical procedure with minimum perioperative complications and short learning curve. Methods:From Apr. 2012 to Apr. 2013, 110 cases of male patients with bladder cancer received this procedure in our department, with a median age of 64 (35-83) years;Preoperative characters, surgical parameters, perioperative complications, pathology, long-term complications and short-term prognosis were collected and analyzed. Results:The median number of lymph nodes resected in operation was 12 (8-16);Neurovascular bundles were reserved bilaterally in 65 cases, and unilaterally in 31 cases;The complete procedure including urinary diversion took 4.4 (2.2-6.0) hours, with a median time of opened abdominal cavity of 43.0 (5.0-75.0) minutes;The median blood loss was 140.0 (50.0-600.0) mL, and 4 patients needed transfusion; Median time of abdominal and pelvic drainage was 10.0 (6.0-15.0) days, the median gastrointestinal recovery time was 2.5 (1.0-12.0) days, and the median postoperative hospital stay was 17.0 (10.0-39.0) days;Grade 2 Clavien-Dindo classiifcation (CDC) of surgical complications that required medical intervention were found in 19 cases, CDC grade 3 or above were found in 8 cases;Mild to moderate postoperative ileus happened in 5 cases, all recovered in median 2 (1-4) weeks with supportive treatments;There were no perioperative deaths. All samples were sent to pathological analyses. After a median follow-up of 9 (3-15) months, no complications of or above CDC grade 3 happened, and there were no recurrence. Conclusion:Complete retrograde radical cystectomy in male bladder cancer provided clear anatomical approach, reliable neurovascular bundle preservation, less blood loss, limited abdominal organs disturbance and better surgical exposure; With respect to tumor control, more peritoneal was retained for subsequent abdominal cavity reconstruction. The introduced procedure effectively speeded up gastrointestinal recovery, reduced postoperative complications, especially the incidence of ileus and its severity, and shortened hospital stay. The learning curve of this procedure for urologists was short, and further investigation was warranted.

Objective To explore the correlation of pulse pressure(PP) and outcome in refractory septic shock patients.Methods A total of 68 patients with refractory septic shock consecutively admitted in our ICU from January 2012 to December 2012 were retrospectively studied.Hemodynamic data and arterial lactate concentration were collected at the time of admission and 24 hours after admission.The outcome of Day 28 post-diagnosis was also recorded.Results (1) Compared with the survivors,heart rate(HR) at 24hours after admission was higher in non-survivors,while 24 h lactate clearance rate (rLac) was lower in them (P < 0.05).Other hemodynamic parameters showed no difference between the non-survivors and the survivors at 24 hours after admission,including central venous pressure (CVP),mean arterial pressure (MAP),systolic blood pressure(SBP),diastolic blood pressure(DBP),PP,pulse pressure/heart rate (PP/HR),pulse pressure/mean arterial pressure(PP/MAP),pulse pressure/systolic pressure(PP/SBP),pulse pressure/diastolic pressure (PP/DBP),the value of SBP above MAP (SMP) and the value of DBP below MAP(MDP).(2)The mortality rate was higher in the patients with HR≥100 b/min than those with HR < 100 b/min,but without statistical significance (56.25% vs 36.11%,P =0.096).Compared with the survivors,no matter with HR≥100 b/min or HR < 100 b/min,lactate(Lac) at the 24 hours after admission was higher in all the non-survivors (P < 0.05),while with lower rLac (P < 0.05).In those with HR ≥100 b/min,the following hemodynamic parameters were higher in the non-survivors than in the survivors,including PP,PP/HR,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (all P values < 0.05),while no statistical difference was observed in those with HR < 100 b/min.(3)The mortality rate showed no statistical difference in those with MAP≥85 mmHg(1 mmHg =0.133 kPa) and with MAP < 85 mmHg(42.42% vs 48.57%,P =0.611).No matter MAP≥85 mmHg or MAP < 85 mmHg,compared with the survivors,all the non-survivors had higher Lac at the 24 hours after admission (P < 0.05),while with lower rLac (P < 0.05).In those with MAP≥85 mmHg,HR was higher in the non-survivors than the survivors (P < 0.05).In those with MAP < 85 mmHg,compared with the survivors,the non-survivors had higher PP,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (P <0.05),while with lower DBP (P <0.05).Conclusion PP is correlated with the outcome in refractory septic shock patients.When the HR and MAP differ,PP has different effect on the outcome and contributes more to the tissue perfusion and outcome in those with higher HR and lower MAP.
