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.

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.

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.

Objective To investigate the effects of Dangshen (DS) extract saponins alleviating apoptosis in ischemia-reperfusion injury (I/R) of renal grafts and the mechanism. Methods The I/R injury model in SD rats was established after kidney transplantation. The SD rats were randomly divided into the following 3 groups (n = 20): sham operation group, I/R model group, DS saponin intervention group. Blood urea nitrogen (Bun) and creatinine (Scr) levels were determined at the 24th h after operation; apoptosis index (AI) was detected by using TUNEL method; the expression of Bcl2 and bax mRNA was detected by RT-PCR. Results As compared with the sham operation group,the blood Bun and Scr levels were significantly increased in the I/R model and DS saponin intervention groups (P＜0. 05). As compared with the DS saponin intervention group, the blood Bun and Scr levels were significantly increased in the I/R group (P＜0.05). The AI was significantly increased in the I/R model group and DS saponin intervention group. After DS saponin intervention, the AI was decreased from 40. 28 % in the I/R model group to 28. 45 % in the DS saponin intervention group (P＜0. 05). The expression of Bcl-2 mRNA in DS saponin intervention group and I/R model group was significantly decreased as compared with the sham operation group (P＜0. 05), but that of Bax mRNA was significantly increased in the I/R model group and DS saponin intervention group as compared with the sham operation group (P＜0. 05). After DS saponin intervention, the expression of Bcl-2mRNA was increased from 0. 25 in the I/R model group to 0. 391 (P＜0. 05), and that of Bax mRNA was decreased from 0. 565 in the I/R model group to 0. 473 (P＜0. 05). Conclusion DS extract saponin could significantly alleviate apoptosis in the I/R injury of renal grafts possibly by up-regulating the expression of Bcl-2 mRNA and down-regulating the expression of Bax gene.

Objective To summarize the experiences of diagnosis and treatment of dermatofibrosarcoma protuberans (DFSP). Methods The clinical data of 16 patients with DFSP were analyzed retrospectively. All the patients with DFSP underwent extensive tumor resection (3～5cm margin from the tumors).Free full-thickness skin flap transplantations was performed on 6 cases , three cases received skin flap shifting operations, and 1 patient with abdominal wall deficiency was repaired by artificial mesh . Results All the 16 patients presented as painless cutaneous nodules which enlarged slowly, but the majority of the tumors grew quickly in recent shorter time. Ten cases were primary tumors, and six were recurrence. The time of recurrence after surgery ranged from 3 months to 10.5 years with 1～3 times recurrence. There was no operative complications. Eleven patients were followed-up for 1～11 years and all survived,only one patient developed tumor local recurrence seven years after surgery. Conclusions A slowly enlarged painless cutaneous or subcutaneous nodules quickly growing in recent time is the clinical characteristic feature of DFSP. Extensive tumor resection is the treatment of primary DFSP.
