Objective To investigate the clinical efficacy of Bushen Tongdu Capsule for treating patients with rheumatoid arthritis (RA, TCM syndrome of kidney-deficiency with cold). Methods Totally 71 RA patients were randomly divided into treatment group (36 cases) that was treated with Bushen Tongdu Capsule and control group (35 cases) that was treated with tripterygium glycosides tablet. Both groups were treated for 12 weeks. The signs and symptoms, the state of illness, and laboratory index were observed before and after treatment. Results The total effective rate was 72.22% (26/36) in the treatment group, and 62.86% (22/35) in the control group, without statistical significance (P>0.05). After treatment, simplified disease activity index, TCM syndrome integrals, tender joint count, swollen joint count, overall evaluation from patients, overall disease evaluation from doctors, rest pain, morning stiffness time, average hands grip strength, 20 m walking time, healthy condition questionnaire score, and C-reactive protein were significantly improved in both groups (P<0.01, P<0.05). Compared with control group, TCM syndrome integrals changed more significantly, with statistical significance (P <0.05). Conclusion Bushen Tongdu Capsule can relieve symptoms and signs of RA patients (TCM syndrome of kidney-deficiency with cold) effectively.

Objective To evaluate the clinical application of anterior approach microendoscopic discectomy for cervical spondylosis. Methods Clinical data of 21 cases of cervical spondylosis from October 2001 to June 2002 treated by anterior approach decompression with bone allograft or autograft for cervical fusion by means of microendoscopic discectomy system were reviewed. Results The mean intraoperative blood loss was 150 ml. The drainage was removed 48 hours and the stitches taken out 5 days after the operations. The mean hospital stay was 10 days. All the patients got out of bed for motion wearing a cervical collar 2 days after the operations. Follow-up ranged 6～12 months with a mean of 9 months.The outcome was determined using Odom grading. Of the 21 cases, 16 were classified as excellent results, 4 as good, 1 as poor, the rate of excellent or good results being 95%.Complications were found in 3 cases:rupture of threaded fusion cage in 1 case;hoarseness in 1 case;and multiple infarction of brain stem in 1 case. Conclusions Anterior approach microendoscopic discectomy in the treatment of cervical spondylosis has the advantages of minimal invasion and rapid recovery. It offers a clear surgical vision for vertebral posterior margin and effective protection for blood vessels and nerves, conforming to the standards of minimally invasive surgery.

Objective To investigate the effects and safety of human hepatocytes transplantation in vivo for the treatment of liver failure. Methods The primary human hepatocytes were collected from normal liver tissue donated by healthy volunteers and preserved by cryopreservation technique. After thawing, the hepatocytes were transplanted into the spleen of patients with severe hepatitis through catheterization of the femoral artery. Then the changes in clinical symptoms, serum biochemical indexes and MRI signals of the spleen were observed in the patients. Results A total of 2?10 10 hepatocytes were isolated from normal liver tissue of healthy volunteers and 75% of the hepatocytes were alive after cryopreservation and thawing. The number of transplanted hepatocytes was 2?109. In the recipients, the clinical symptoms were markedly improved, serum levels of bilirubin, NH_3, ALT and AST were significantly reduced, but that of PTA remarkably increased, after hepatocyte transplantation. The follow-up examination was performed 80d and 270d after discharge from the hospital, and it was showed that all the serum biochemical indexes returned to normal and signals of the hepatocytes were found in the spleen. Conclusions Hepatocyte transplantation is a safe and effective therapy for severe hepatitis. The transplanted hepatocytes can proliferate and differentiate in the spleen to replace or partially compensate the liver function of synthesis, detoxication and metabolism. Contrast enhanced MRI can be a new method for follow-up study of transplanted hepatocytes.

Objectives To evaluate the efficacy and safety of h um an hepatocyte transplantation in the treatment of severe hepatitis induced by dr ugs. Methods The primary human hepatocytes were isolated from t he liver of a healthy donor, and they were then cryopreserved. The thawed hepato cytes were transplanted into the patient's spleen via a femoral artery catheter. 2?10~10 hepatocytes were harvested, and 70% of thawed hepatocytes were vi able, and 2?10~9 vital hepatocytes were transplanted. Results One month after the transplantation, clinical symptoms of the recipient were a meliorated obviously, and the levels of BIL, NH3, ALT and AST lowered, while PA elevated. 50 days after discharge from the hospital it was found that biochemica l parameters returned to normal values, and the hepatocyte signal could be detec ted in the spleen with MRI. Conclusion Hepatocyte transplantati on is safe and efficacious.

Objective To establish the method for quality control of ethyl-acetate parts of Ferula sinkiangesis. Methods HPLC was used to detect the contents of ferulic acid, farnesiferol A and farnesiferol C. Waters XTerra RPC18 column (250 mm×4.6 mm, 5 μm) was used; acetonitrile-0.1% phosphoric acid was as mobile phase with gradient elution; flow rate was 1.0 mL/min; detective wavelength was 324 nm; temperature was 30℃; sample volume was 10 μL ResultsFerulic acid, farnesiferol A, and farnesiferol C showed a good linear relationship range from 0.05– 1.0 mg/mL, 0.132–2.64 mg/mL, and 0.118–2.36 mg/mL, respectively. The average recovery rates were 99.34%, 98.96% and 99.24% respectively. The contents of ferulic acid, farnesiferol A and farnesiferol C were 33.4, 76.5, 72.3 mg/g respectively.Conclusion The method was simple, accurate and repeatable, with good repeatability and stability, which can be used for the quality control of ethyl-acetate parts ofFerula sinkiangesis.

A strain was separeted from the Yueqing bay using pine pollen baiting.The vegetative thallus of the separated strain is oval and unincleate.It possesses a cell wall composed of many compact layers of closely pressed scales, which can be resolved where the cell wall is disrupted.The radiating branched extensions of the thallus, the ectoplasmic net, emerges from the sagenogenetosome.Asexual reproduction is by conversion of the vegetative thallus to many biflagellate zoospores, during which tetrads of cells are formed.It was identified with Schizochytrium sp.based on the features mentioned above.

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.
