Objective To examine the distribution of flurbiprofen axetil in cerebral-spinal fluid (CSF) by determining the CSF concentration of flurbiprofen after iv administration. Methods Seventy-two ASA Ⅰ or Ⅱ patients of both sexes aged 18-75 yr weighing 54-82 kg undergoing spinal or combined spinal-epidural anesthesia for lower extremity or lower abdominal surgery were studied. Flurbiprofen axetil 1 mg/kg was injected intravenously.CSF 2 ml and venous blood 3 ml were obtained simultaneously every 5 min after iv injection for 45 min (T1-9 ) for determination of flurbiprofen concentration using high performance liquid chromatography, and the CSF/blood flurbiprofen concentration ratio was caculated. Results Flurbiprofen was not detected in CSF at T1,2 after iv injection in 3 and 4 patients. The CSF flurbiprofen concentration was significantly higher at T4-9, and CSF/blood flubiprofen concentration ratio higher at T5-9 than at T3 ( P ＜ 0.05). There was no significant difference in CSF flurbiprofen concentrations among T4-9 ( P ＞ 0.05 ) Conclusion Flurbiprofen is detected in CSF after iv injection, the CSF flurbiprofen concentration peaks at 20 min after iv injection and it lasts until 45 min after iv injection.

Objective To study the clinical and pathological characteristics, treatment results and prognosis of primary parotid non-Hodgkin's lymphoma (NHL). Methods All of our 21 patients received operative resection first and were histologically comfirmed as having T-cell (intermediate grade) and 20 B-cell lineage (2 high grade, 6 intermediate grade ,12 low grade) including 7 mucosa-associatied lymphoid tissue (MALT) phenotype. Ann Anbor stages were 16 stage Ⅰ E and 5 stage Ⅱ E lesions. All patients were treated by radiotherapy,of them 11 were also given 2～6 cycle chemotherapy. Results The overall 5-year survival rate was 77.0%. All 5 patients who died did so of distant involvement. Conclusions Our data show that MALT lymphoma can be present as a primary paroid NHL,although it is not included in the Working Formulation. Low-dose radiotherapy is of choice in the treatment. Patients with intermediate or high grade NHL should be given multi-modality therapy.

Objective:To establish a three-dimensional visualization model of craniofacial hard and soft tissues with data based on CT. It could be used in clinic as diagnosis and operation simulation. Methods:Original data of patients' craniofacial hard and soft tissues by CT scanning was transferred into the system. After 2-D and 3-D image preprocessing, advanced Marching Cubes Algorithm (Marching Tetrahedron Algorithm) was used for surface fitting;3-D volume rendering was accomplished by footprint method. Results: The whole craniofacial frame and its surface could be observed clearly in reconstructed 3-D Model. Furthermore, the 3-D Model could be seen from any sight angle and sectioned in any direction and place. Doctors could observe the characters of craniofacial deformity for more details. Conclusion: The problems of X-ray reflection of metal brackets, control of X-ray dosage and time spending in 3-dimensional visualization model reconstruction were solved. This model could be used in clinic for diagnosis and operation simulation.

Objective To observe the changes of endothelin-1 (ET-1) and prostaglandin E2 (PGE2) in exhaled breath condensate (EBC) and serum of patients with acute respiratory distress syndrome (ARDS) after treated by Qingfeitang and investigate its clinical value. Methods 52 ARDS patients receiving mechanical ventilation at intensive care unit (ICU) were divided into the Qingfeitang treatment group and the control group, with 26 cases in each group. The EBC were collected by Ecoscreen condenser within 24 h after diagnosis of ARDS and on the 5th day of medication, and the venous blood were collected at the same time. The levels of ET-1 and PGE2 in the EBC and serum of different period were measured by EIA. Results (1) After treatment, The levels of ET-1 in EBC and serum of the Qingfeitang treatment group were significantly lower than those of the control group. (2) After treatment, the levels of PGE2 in serum of the Qingfeitang treatment group were significantly lower than that of the control group. (3) The oxygenation index difference before and after treatment of Qingfeitang in the treatment group was higher than in the control group. (4) The duration of mechanical ventilation of the Qingfeitang treatment group was significantly less than that of the control group. Conclusions Qingfeitang could be an effective method for alleviating acute respiratory distress syndrome.

BACKGROUND: Unrepaired bucket handle meniscus tear(BHMT)could result in partial or total meniscectomy,which aggravates the degeneration of knee joint.The long-term,large sample studies regarding the success rate of BHMT repair are few.OBJECTIVE: To retrospectively analyze the clinical result of arthroscopic BHMT repair and explore the preoperative diagnosis,repair technique,treatment effect evaluation and influential factors,so as to investigate ideal repair method of large meniscus tear injury.METHODS: From May 2002 to November 2005,90 patients with repairable BHMT were treated in Sports Medical Center of Beijing Jishuitan Hospital.Of the 90 patients,61(63 menisci)were followed up for over 2 years with an average duration of 38months(24-66 months).The indications of BHMT repair include red-red area and red-white area injuries,reductable,meniscus with no compound tear or degeneration.RESULTS AND CONCLUSION: Of the 61 followed up patients,53 menisci in 51 patients(84%)were assessed by second-look arthroscopy; 53 of 61 patients(87%)were asymptomatic,4(6%)patients were partial asymptomatic and 4(6%)had recurrent locking showing failure.Second-look arthroscopic examination showed that 44 menisci(83%)were healed completely,5(9%)partially healed,and 4(7%)not healed.The total failure rate was 8%(5/63),and success rate was 92%,including complete healed,partial healed,asymptomatic and partial asymptomatic patients.For large bucket-handle meniscus tears involving red-red and red-white zones,reliable arthroscopic hybrid suture technique,provides stable suture strength along the whole length of injured region and consequently achieves improved clinical outcomes in combination with anterior cruciate ligament.
