Objective To compare the differences in histological morphology and hemodynamics between benign and malignant tumor, as well as differences between the different perfusional regions in tumors of the same type. Methods Thirty cases with malignant breast carcinoma and 30 cases with fibroadenoma were inspected by contrast enhanced ultrasound with time-intensity quantitive analysis. Perfusion index like peak intensity(PI), area under the curve(AUC), time to peak(TTP) and wash-out time (WOT) were collected both inside and at the margin of focus. The ultrastructures of new microvessesl were observed routinely with microscopy and transmission electron microscopy. Results The curve of malignant tumor group was characterized as ascend rapidly and drop slowly while the benign group presented as ascend slowly and drop rapidly. The AUC and WOT of malignant tumor group were significantly higher than that of benign group,while the PI and TTP had no statistical difference. In malignant tumor group,PI, AUC and WOT of the margin of focus were significantly higher than that of inside region of focus,while TTP was the opposite. However,there was no statistical differences between the perfusion parameter inside and outside of focus in benign group. The ultrastructures of newly built blood vessels in malignant group had strong ability to split,which was different from normal endothelium cells but was similar to other tumor foci. The margin of foci were characterized with dilatating and distorting vessels,and the center of the foci were occupied by narrow,occlusive new vessels and contracted anamorphic endothelium cells and pericytes. Rich microvessel areas located in the margin of foci. Conclusions The perfusion pattern,modality of time-intensity curve, mean perfusion parameter and variance of regional perfusion parameters are valuable diagnostic basis in discriminating benign and malignant breast tumor. The density,modality,distribution,structure and function of new microvessels in tumor focus are also keystone factors when tumors are assessed by means of imaging.

Objective To evaluate the clinical results of arthroscopic reconstruction of posterior cruciate ligament (PCL) via posteromedial,posterolateral and posterior trans-septal portals with the preservation of intact meniscofemoral ligaments and remnant PCL fibers.Methods Nine patients with PCL injuries were treated with autogenous hamstring tendons arthroscopically through routine arthroscopic portal,posteromedial portal,posterolateral portal and posterior trans-septal portal with preservation of intact meniscofemoral ligaments and remnant PCL fibers.Tibial tunnel of 1-1.5 cm was made below the lateral articular surface of PCL tibial attachment via arthroscopic posterolateral approach.Femoral tunnel of 1 cm was made posterior to the articular cartilage of the medial femoral condyle through anterolateral approach.Autogenous tendon graft was positioned in the knee joint through the navigation of tibial and femoral double-folded silk loops that traversed the bone tunnels and was fixed with bioabsorbable interface screws at both ends.Knee function was evaluated with Lysholm scale six months postoperatively.Results All patients were followed up for average 8.6 months (range,7-14 months).None of the patients had knee extension limitation six months postoperatively,but there were two patients with 10°-15° flexion limitation and one withⅠ degree positive result in posterior drawer test.Lysholm knee score was increased from preoperative (47.6 ± 14.9)points to (92.9 ±4.6) points at six months postoperatively (P ＜0.01).Conclusion PCL reconstruction via posteromedial,posterolateral and posterior trans-septal portals can obtain clear vision (with no blind area),safe operation,accurate positioning of tibial attachment and affirmative short term treatment results.

OBJECTIVE To investigate the clinical distribution and resistance of Alcaligenes xylosoxidans,discussing risk factors of nosocomial infection and measures of prevention and treatment.METHODS We retrospectively analyzed 1323 isolated strains of Al.xylosoxidans in our hospital from Sep 2004 to Aug 2006.RESULTS For specimen from which Al.xylosoxidans was examined,sputum accounted for 99.85%,being the highest percentage.Al.xylosoxidans was especially distributed at respiratory ward(46.94%) and intensive care unit(ICU) ward(12.77%).Then was cardiovascular ward,endocrinology ward and hematology ward.The antibiotic drugs which had the high drug-resistance rate(i.e.more than 98%) were aminoglycoside(amikacin and gentamicin),quinolone(ciprofloxacin) and cefepime.But the drug-resistance rate to carbapenems,?-lactam/?-lactamase inhibitor combinations and the third generation cepholosporins(cefoperazone and ceftazidime) was less than 5%.CONCLUSIONS It is important for clinic to strengthen the disinfection for hospital environment and to use antibiotic drugs reasonably in order to control colonization and spread of Al.xylosoxidans in hospital.

For promoting the quality evaluation of Gardenia resource,a UPLC method for the determination of 4 compounds (geniposidic acid,geniposide,crocin-1 and crocin-2) in Gardeniae Fructus was established.The UPLC separation was performed on an Waters Acquity UPLC BEH-C18 (2.1 mm× 100 mm,1.7 μm) column eluted with the mobile phases of acetonitrile-0.1％ formic acid solution in a gradient mode at a flow rate of 0.3 mL· min-1.The detection wavelengths were 240 nm and 440 nm,respectively.Under the optimum conditions,the calibration curves of four analysis were linear in the range of 0.0065-0.0096 μg· mL-1,with correlation coefficients more than 0.9995.The limits of detection (LODs) of four analysis were in the range of 0.0386-0.1875 μg· mL-1.As the results of determination of 4 compounds of 12 batches of Gardeniae Fructus showed,there was great differences between the contents of the 4 compounds,the contents of geniposide were 2.44％-6.96％,while the contents of crocin-1 were 1.26％-3.04％.In addition,fingerprints of 12 batches of Gardenia resources were built using ChemPattern software,and analysis and exploration over the detection results of several samples were carried out using multivariate statistical method (similarity analysis,principal component analysis and cluster analysis).The present study provided a reference to value the importance of this method in the quality evaluation and quality control of Gardeniae resources and slices.

OBJECTIVETo explore the effect of Danlou Tablet (DT) on arrhythmia model rats induced by transient myocardial ischemia/reperfusion (I/R).

METHODSTotally 45 healthy Wistar rats were randomly divided into 3 groups, the sham-operation group, the model group, and the DT group, 15 in each group. Rats in the sham-operation group and the model group were administered with distilled water by gastrogavage at the daily dose of 0.1 mL/kg. Rats in the DT group was administered with 0.53 g/mL DT suspension by gastrogavage at the daily dose of 0.1 mL/kg. All medication was lasted for 10 successive days. The myocardial I/R experiment was performed at 1 h after the last gastrogavage. ECG was performed before ligation and at I/R. The jugular arterial blood pressure of all rats was measured during the whole course. ST segment changes were observed at each time point of I/R. The ventricular fibrillation, the premature ventricular, the number and the duration of ventricular tachycardia within 30 min reperfusion were also observed. Activities of Na(+)-K+ ATPase and Ca2+ ATPase in the myocardium homogenate were detected as well.

RESULTSThe jugular arterial blood pressure and the heart rate were slightly lower in the DT group than in the model group, but with no statistical difference (P > 0.05). Compared with the sham-operation group, the degree of ST segment was obviously elevated in the model group at 0, 5, and 7 min (P < 0.05). It was significantly lower in the DT group than in the model group (P < 0.01). ST seg ment was more elevated at 5 min than at 0 min in the model group, but the degree of ST segment elevation was still obviously lower in the DT group than in the model group (P < 0.05). There was no statistical difference in the degree of ST segment elevation at 7 min between the two groups (P > 0.05). At 0 min when the decrement of ST segment exceeded one half the ischemia, there was no statistical difference in the degree of myocardial ischemia between the model group and the DT group (P > 0.05). Compared with the model group, the incidence of fatal and nonfatal ventricular fibrillation, the frequency and duration of ventricular tachycardia and premature ventricular beats were obviously lessened, and activities of Na(+)-K+ ATPase and Ca(2+)-ATPase increased (all P < 0.05).

CONCLUSIONSDT could significantly protect arrhythmias induced by transient I/R. Its effect might be related to lowering the degree of myocardial ischemia, and increasing ion transport channel related enzyme activities.
