ABSTRACT
Objective To access the efficacy of the arterial based complexity (ABC) scoring system in predicting complexity of LPN.Methods A total of 70 patients underwent laparoscopic partial nephrectomy from January 2013 to November 2015 were enrolled in the retrospective analysis.Among those patients,53 (75.7％) were males and 17 (24.3％) were females.Their mean age was 52 years,ranged from 44 to 61 years.The average BMI was 28 kg/m2,ranged from 25 to 32 kg/m2.Before operation,the average creatinine was 70.5 μmol/L,ranged from 60.5 to 81.0 μmol/L.43 patients accepted the procedure via retro-peritoneal approach and 27 patients accepted the procedure via peritoneal approach.38 tumor located in the left kidney and 32 tumor located in the right kidney.By using ABC scoring system,four readers independently scored contrast-enhanced computed tomography images of 70 patients who underwent laparoscopic partial nephrectomy.Interobserver variability was assessed with kappa values and percentage of exact matches between each pairwise combination of readers.Logistics regression was used to evaluate the association between reference scores and ischemia time,estimated blood loss,operation time.Results The operative duration ranged from 100 to 180 min,mean 147 min.The mean ischemic time ranged from 15 to 37 min,mean 24 min.The average blood loss was 210 ml (ranging 50-380 ml).The mean hospitalization was 16 days (ranging 11-21 days).The urine leakage was noticed in 2 patients after the operation.The size of tumor ranged from 1.8 to 3.0 cm,mean 2.5 cm.The pathological classification included renal cell carcinoma in 65 cases,renal cell carcinoma with cystic changing in 2 cases,renal chromophobe cell carcinoma in 2 cases,right renal solitary fibroma in 1 case.Based on the ABC scorirng system,15 cases were in 1 degree,29 cases were in 2 degree,17 cases were in 3S degree and 9 cases were in 3H degree.Pairwise comparisons of readers' score assignments were significantly correlated;average kappa =0.492,across all reader pairs.The average proportion of exact matches was 65％,the average proportion that differ between a level or less than a level was 98.6％.Logistics regression between the complexity score system and surgical outcomes showed significant associations between reference category assignments and warm ischemia time and estimated blood loss (P ＜ 0.05),but showed no significant associations with operation time (P ＞ 0.05).Conclusions The ABC scoring system for LPN demonstrated good correlation with perioperative morbidity.This system is a novel anatomy-reproducible tool developed to help patients and doctors understand the complexity of renal masses and predict the outcomes of kidney surgery.
ABSTRACT
Objective To establish a diagnostic scoring system for coronary artery disease(CAD)in patients with diabetic foot(DF)and evaluate its application efficiency. Methods The clinical data of 445 DF inpatients were analyzed retrospectively in this case?control study. These patients were divided into the CAD group(n=372,DF with CAD)and the control group(n=73,DF without CAD)according to the presence or absence of CAD. Risk factors were screened from related clinical factors examined through multiple logistic regression analysis for CAD in patients with DF and were assigned according to odds ratio(OR)to establish the scoring system for diagnosis of CAD in patients with DF. Application efficiency of the di?agnostic scoring system was tested by calculating area under the receiver operating characteristic(ROC)curve. Results The multiple logistic re?gression analysis showed that risk factors for CAD in patients with DF were age,male sex,the duration of diabetes≥10 years,the ankle?brachial in?dex(ABI)≤0.9,body mass index(BMI)≥25 kg/m2 and chronic renal insufficiency. According to ORassigned age(0.9=0,≤0.9=2),BMI(<25 kg/m2=0,≥25 kg/m2=3)and chronic renal insufficiency(absent=0,present=3)scores. Area under the ROC curve of the diagnostic score scheme was 0.758(0.682?0.835),the standard error was 0.039,and the point of the diagnosis of CAD was 7. Conclusion The scoring system established in the study is efficacious,simple and practical,which provides an important reference for CAD in patients with DF.

ABSTRACT
Objective To inveatigate the effect of 15-HETE, a metabolite of arachidonic acid, on isolated hypoxic pulmonary arterial ringa ( PARs) , trying to find appropriate treatment for pulmonary hypertension and its complications during anesthesia in order to avoid hypoxemia. Methods Sixteen healthy Wistar rats of either sex weighing (230 ? 10) g were randomly divided into two groups : A control group breathing fresh air (FiO2 =21%) and B hypoxia group breathing hypoxic air (N2 = 90% , O2 = 10% ) in a hypoxic box. After breathing hypoxic air for 9 days the animals were anesthetized. Heart and lungs were immediately removed and PARs (0.5-1.0 mm in diameter and 3 mm in length) were prepared. Four PARs were prepared from each animal. The PARs were suspended in baths filled with Krebs-Hensleit (K-H) solution maintained at 37℃ and aerated with 95% O2 and 5% CO2. Preload was gradually increased to 0.3 g in 30 min. The isometric tension was measured using a four-channel force-displacement transducer. 15-HETE was added to K-H solution and the concentration was gradually increased from 10-8 to 10-6 mol?L-1 at 5 min intervals. Contractility of PARs was analyzed by a software of Medlab 6.0. Concentration-tension curve was drawn and contraction rates were calculated. 2 mmol?L-1 4-AP, 10-2 mol?L-1 TEA and 10-6 mol?L-1 GLYB were added to separate K-H solution baths and 40 min later 15-HETE was added in order to detennine the effect of difierent potassium channel blockers on contraction response of PARs to 15-HETE. Results With increasing concentration from 10-8 to 10-6 mol?L-1 , 15-HETE increased PARs tension gradually in a dose-dependent manner from 106% ?6% to 139% ? 4% in group A and from 113% ?6% to 163% ?6% in group B. The difference in PARs tension between group A and B was statistically significant (P
ABSTRACT
Objective To investigate the correlation between PaCO2 and cerebral blood flow (CBF), cerebral metabolism of oxygen (CMRO2), glucose (CMRglu) and lactate (CMRlact) and intracranial pressure during intracranial surgery. Methods Twenty ASA Ⅰ - Ⅱ patients (6 male, 6 female), aged between 26-54yr, weighing (65 ? 11) kg scheduled for elective intracranial surgery were studied. The patients were unpremedicated. Before general anesthesia radial artery was cannulated and a catheter was inserted into internal jugular vein and advanced cranially until jugular bulb. Lumber puncture was performed at L3-4 and a catheter was inserted into subarachnoid space for 3 cm, for pressure monitoring and CSF sampling. Anesthesia was induced with diazepam 10mg, fentanyl 3-4?g?kg-1, propofol 2mg?kg-1 and vecuronium 0.08mg?kg-1 iv. The patients were mechanically ventilated with a mixture of oxygen and argon (O2 : argon = 3 : 1) after tracheal intubation. Anesthesia was maintained with sevoflurane and intermittent iv boluses of vecuronium. Arterial and cerebral venous blood gases, glucose and lactate levels, CBF, ICP and CSF level of lactate were determined before anesthesia when patients were awake(Ⅰ) and during anesthesia when PETCO2 = 40, 30, 20 mm Hg (Ⅱ,Ⅲ,Ⅳ). CBF was measured by modified Kety-Schmidt inert gas saturation technique with argon. CMRO2 and CMRglu were calculated based on the difference in their arterial -cerebral venous blood levels. Results At PETCO2 20mm Hg (Ⅳ) CBF decreased by 57.75% and CMRO2 by 58.70% as compared with the baseline; CMRglu decreased by 46.93% as compared with the baseline. There was no significant change in lactate level, jugular venous blood O2 saturation and pH. ICP decreased from (22.14 ? 7.88)mm Hg( Ⅰ) to (17.57?5.03)mm Hg( Ⅱ ),(13.43?4.89)mm Hg(Ⅲ) and (10.00? 2.31)mm Hg(Ⅳ) and the differences were significant. All measurements were done when MAP and HR were stable. PET CO2 was (10? 2) mm Hg lower than PaCO2 . Conclusions Cerebral blood flow, cerebral oxygen and glucose metabolism and intracranial pressure change with changes in PET CO2 . Cerebral vascular reactivity to CO2 is not impaired by 1.3 MAC sevoflurane. Mild hypocapnia is necessary during neurosurgery.
