Objective To compare the efficacy of aspirin and rivaroxaban on prevention of deep vein thrombosis after total knee repalcement.Methods Patients (200 cases) who were given total knee replacement were selected,and the patients in aspirin group (98 cases) were administered with asprin after 12 h treatment,and the patients in rivaroxaban group (102 cases) were administered with rivaroxaban after 12 h treatment.The efficacy of aspirin and rivaroxaban to prevent deep vein thrombosis after total knee repalcement was evaluated by blood coagulation indexes,D-dimer level,and complication during perioperative period.Results Before surgery,there was no statistically significant difference on coagulation indexes between two groups.After 3 d of operation,there was no statistically significant difference in Plt,APTT,and PT between two groups.The FIB level of aspirin group was improved significantly and higher than that of rivaroxaban group (P ＜ 0.05).While the FIB level of rivaroxaban group was close to the normal level.Before operation,there was no statistically significant difference in D-dimer between two groups.After 1,3,and 7 d of operation,the D-dimer levels in two groups were increased.But the D-dimer levels of 3 and 7 d after operation began to decline.After 1,3,and 7 d of operation,the D-dimer ofrivaroxaban group was lower than that of aspirin group (P ＜ 0.05).During perioperative period,there was no statistically significant difference on DVT between two groups.Conclusion Rivaroxaban could prevent the formation of DVT effectively and reduce the D-dimer with good anticoagulation and high safety.It is worthy of clinical application.

PURPOSE: The purpose of this study was to ascertain whether radiation adaptive response could be induced by high dose I-131 therapy in patients with differentiated thyroid cancer. MATERIALS AND METHODS: Lymphocytes from 21 patients (7 males, 14 females, mean age 55+/-12 years) were collected before and after administration of 5,550 MBq (150 mCi) I-131. They were exposed to a challenge dose of 1 Gy gamma rays using a Cs-137 cell irradiator. The number of ring-form (R) and dicentric (D) chromosomes was counted under the light microscope, and used to calculate the frequency of chromosomal aberration. Ydr, which was defined as the sum of R and D divided by the total number of counted lymphocytes. RESULTS: Ydr in patients before I-131 therapy (0.09+/-0.01) was not different from that of controls (0.08+/-0.01). Ydr was significantly increased to 0.13+/-0.02 (p<0.0001) after I-131 therapy. Increase of Ydr after the challenge irradiation of 1 Gy was significantly lower in patients after I-131 therapy than before I-131 therapy (0.17+/-0.03 vs 0.21+/-0.02, p<0.0001). Cycloheximide (CHM), an inhibitor of protein synthesis, abolished this effect. Ydr after CHM (0.20+/-0.01) was significantly higher than Ydr after I-131 therapy (0.17+/-0.03, p<0.0001), but was not different from Ydr before I-131 therapy (0.21+/-0.02). CONCLUSION: High dose I-131 therapy induces an adaptive response in peripheral lymphocytes of patients with well-differentiated thyroid cancer, which is associated with protein synthesis.

Objective:To determine ochratoxin A ( OTA ) in Chinese herbs by high performance liquid chromatography-tandem mass spectrometry method ( HPLC-MS/MS) . Methods: The samples were extracted by 80% methanol water solution and purified by immunoaffinity column. The chromatographic separation was carried out on a C18 column, the mobile phase was methanol-acetonitrile-0. 01 mol·L-1 ammonium acetate, and then OTA was detected by MS/MS in an ESI(-)-MRM mode. Results:The limit of detection was 0. 1 μg·kg-1 , the average recoveries ranged from 84. 8% to 91. 2%, and the relative standard deviations ( RSD) ranged from 3. 6% to 8. 1%(n=9). Conclusion:The method is accurate,sensitive and simple, and suitable for the determination of ochratoxin A in Chinese herbs.

To investigate the clinical efficacy of distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg for the treatment of traumatic chronic osteomyelitis of lower leg. A total of 25 patients with traumatic chronic osteomyelitis of lower legs were from Department of Burn and Plastic Surgery, Beijing Jishuitan Hospital from January 2002 to June 2008. All the patients were treated with distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg after thoroughly debridement. Among them, 6 patients were treated with myocutaneous flap with nutrient vessel of saphenous nerve, and 19 patients were treated with myocutaneous flap with nutrient vessel of sural nerve. The sizes of the flaps were 5 cm×3 cm-18 cm× 12 cm, with attached muscles were 3 cm×3 cm-8 cm×5 cm. The lengths of the pedicles were 5-12 cm. All transplanted myocutaneous flaps survived well. A 6-24 months follow-up of all patients was obtained. The shape and texture of the myocutaneous flaps were good. And there was no recurrence of osteomyelitis. Results suggested that the distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg had reliable blood supply and satisfied efficacy, which was a good method for repairing traumatic chronic osteomyelitis of lower leg.

Background and purpose: Langerhans cell histiocytosis (LCH) is a rare complex reticulocndotheliai disease that often invades the head and neck. There in no consensus of treatment. Radiation is one of the treatment options for the localized lesions. Our aim in the study was to analyze the radiotherapeutic efficacy for LCH in the head and neck region. Methods: 8 patients with eosinophilic granuloma (EG) and 1 case with Hand-Schuller-Christian disease (HSC) were treated with radiotherapy in our hospital from July 2000 to May 2007. Their clinical data were retrospectively analyzed. Results: 5 cases of EG were treated with tumor partial excision and radiation, while the other 3 cases of EG were given radiation alone after biopsy. The HSC was administered with radiation and endocrine therapy. All the patients were followed up for 1.5-8 years. The response rate was 89%. Conclusion: Radiotherapy of LCH is an effective modality, but the optimal dose needs to be further studied.
