Objective To study the effects of thrombolysis for the treatment of acute cerebral infarction (ACI) in early stage (within 6 hours after onset) in hospital, and to demonstrate the benefit of urokinase in the treatment of acute cerebral infarction. Method The patients with cerebral infarction treated with UK within 3hours after onset in the emergency department were enrolled as the study group, and those treated with thrombolytics in the neurological unit over the same period were taken as the control group. Results The average time from onset of ACI to starting thrombolytic therapy was 45 minutes in the study group and 80 minutes in the control group.The number of patients treated with thrombolysis within 3 hours was 39 ( 14.4% ) in the study group and 29 (10.5%) in the control group. There were significant differences in the scores of the National Institutes of Health Stroke Scale (NIHSS) after thrombolytic therapy and in Bathel index of complete or nearly complete recovery rate between two groups. The length of hospital stay was shorter in patients of the study group than that in the control group. Conclusions The thrombolytic treatment with urokinase employed to the patients in the early stage of acute cerebral infarction leads to better outcomes than that in the later stage.

Objective To explore the auxiliary effect of ultrasonic guidance for percutaneous transhepatic varices embolization ( PTVE) for the treatment of hemorrhage of upper gastrointestinal with cirrhosis. Methods Fifty-two patients arranged PTVE by ultrasonic guidance were considered as observation group,and 37 patients arranged PTVE by blind paracentesis were considered as control group. The paracentesis success ratio,time of paracentesis,results and rate of complications in the two groups were compared. Results The achievement ratio of one-time puncture in observation group(73. 1%) was significantly increased than that in control group(43. 25). The differences were statistically significant(P<0. 05). The time of paracentesis in observation group (2. 3±0. 6) min was shorter than that in control group(4. 2±0. 8) min. The differences were statistically significant(P<0. 05). The rate of embolization rate in observation group(100%) was obviously higher than that in control group(86. 5%),the differences were statistically significant(P<0. 05),and the rate of complications was less than that in control group. Conclusion The ultrasonic guidance plays an important assistant roles for PTVE,it is helpful to determine the location of portal vein and increase the paracentesis succeed ratio and speed. It is safe and deserved to be spread.

Objective To evaluate the effectiveness of scaphoid fracture fixation through dorsal approach and dorsal joint capsule recon -struction in treatment of old trans-scaphoid perilunar dislocation .Methods From October 2010 to October 2013, 12 patients of old trans-scaphoid perilunar dislocation had been treated with open reduction and internal fixation as well as dorsal joint capsule reconstruction through dorsal approach.Among the 12 patients, 9 were males and 3 were females, and they were 22~54 years old (42.3 years old averagely). Preoperative and postoperative wrist functions were evaluated by visual analogue scale (VAS), range of motion (ROM), grip strength and Cooney's standard.Results All the 12 patients were followed-up for 15 to 28 months (24 months averagely).In the last follow-up, the aver-age VAS score was 1.6 point (0~6 point) , and 9 patients of them had no feeling of pain .According to the Cooney ’ s standard,the results were excellent in 2 cases, good in 8 cases, fair in 1 case,and bad in 1 case.The mean time of fracture union was 14~22 weeks (16.8 weeks averagely ) .Conclusion Scaphoid fracture fixation through dorsal approach and dorsal joint capsule reconstruction in treatment of old trans-scaphoid perilunar dislocation can receive good curative effect and satisfactory clinical effect .

Objective To determine the value of oxygenation index in assessing the outcome of mechanical ventilated patients with acute respiratory distress syndrome (ARDS).Methods From September 2008 to September 2013,patients meeting the Berlin definition of ARDS were evaluated in this retrospective study.Data included oxygenation index (PaO2/FiO2) on day before,and day 1 and day 3 after mechanical ventilation.The levels of PaO/FiO2 on day before and day 1 after mechanical ventilation were compared between 28-day survivors and non-survivors.Results There were 236 patients meeting the criteria of the Berlin Definition for diagnosis and treated with mechanical ventilation.The mean score of APACHIE Ⅱ and sequential organ failure assessment (SOFA) at the beginning were (19.1 ± 3.0) and (10.8 ±2.5),respectively,while oxygenation index on day before mechanical ventilation was (150.3 ± 62.6) mmHg.According to the hypoxemia grade,patients were divided into mild (n =36),moderate (n =122) and severe (n =78) ARDS,and their levels of PaO2/FiO2 were (80.1 ± 8.1),(162.3 ± 19.9) and (261.6 ± 22.3) mmHg,respectively.There were 92 non-survivors and 144 survivors.No obvious difference in oxygenation index of non-survivors among on day before、and day 1 and day 3 after mechanical ventilation.There was statistically significant difference in oxygenation index between on day before and day 1 after mechanical ventilation in survivors (P ＜ 0.05).Compared with the survivors,the score of APACHE Ⅱ,SOFA,and oxygenation index on day 3 were associated with increased mortality in the non-survivors,respectively (P ＜ 0.05).In respect to the mortality,the cut-off point of score of oxygenation index set at ＜ 180 mmHg on Day 3,an area under the receiver operating curve (AUC) was 0.749 with statistically significance (P ＜ 0.05),leading to sensitivity 61.7％ and specificity 93.2％.The relationship between prognosis and antibiotic resistance did not have statistically significance.Conclusions Data of oxygenation index on early phage of ARDS may be valuable to predict the outcome.A strong predictor of adverse outcome in such conditions was the score of oxygenation index on Day 3 ≤ 180 mmHg.

A method for the determination of cinoxacin and nalidixic acid in human plasma by reverse-phase high performance liquid chromatography is introduced. The single separation system involves a RP-C18 column, a ultraviolet detector at 254 mn and CH3CN-CH3OH-0.01 mol/L HOOCOOH (30:5:65;pH 4.55). The influence of two kind of buffer (phosphate buffer and oxalate buffer) in mobile phase on the separation were studied. Oxalate buffer can improve tailing peak and decrease detection limits. Three pH values (pH 2.80,4.08,4.55) were studied, pH 4.55 can give best separation result. The detection limits of cinoxacin and nalidixic acid were 0.14 ng and 0.24 ng, respectively.
