BACKGROUND:Increasing evidence has demonstrated that bone marrow mesenchymal stem cel (BMSC) transplantation can promote skin, liver and lung repair in animal models; andLeonurus sibiricus L. has the ability of promoting blood circulation and regulating menstruation.
OBJECTIVE: To investigate the therapeutic effect of BMSC transplantation with leonurine on intrauterine adhesions (IUA) in rabbits and the relevant mechanism of action.
METHODS: After modeled using dual injury method, rabbit models of IUA were randomly divided into five groups: sham-operated group (sham), model group (IUA), BMSC transplantation group, leonurine treatment group and combined treatment group (BMSCs+leonurine). Rabbits in the sham group were only given normal saline rinsing after hysterotomy, while those in the latter three groups were correspondingly given intrauterine BMSC transplantation or/and intragastric administration of 4 mg/kg leonurine for 14 days. Morphological changes of the endometrium were observed using hematoxylin-eosin staining, and expression levels of transforming growth factor β protein, Smad3 protein and interferon-γ mRNA were detected using immunohistochemical staining and real-time fluorescence quantitative PCR, respectively.
RESULTS AND CONCLUSION:Compared with the model group, the degree of IUA was al significantly improved in the other groups, especialy in the combined treatment group. Moreover, BMSC transplantation, leonurine treatment and their combined use al could inhibit IUA-induced increase of transforming growth factorβ and Smad3 protein expression and IUA-induced decrease of interferon-γ mRNA level. Importantly, al these alternations were much more pronounced in the combined treatment group. Our results show that the combined use of BMSC transplantation and leonurine treatment can exert a synergistic effect in the improvement of IUA through the transforming growth factor β/Smad3 pathway.

Objective:To compare the difference and correlation of HPLC and enzyme-multiplied immunoassay test( EMIT) for the determination of CsA in human whole blood. Methods:A total of 119 clinical samples at different concentrations of CsA were collected and respectively determined by HPLC and EMIT. The difference and correlation of the two determination methods were investigated. Results:There was significant difference in the blood concentrations of CsA determined by HPLC and EMIT(P<0. 05). CsA concen-tration determined by EMIT was 26. 2 ng·ml-1 higher than that determined by HPLC, and 95% CI was (14. 6-37. 7) ng·ml-1 . A satisfactory correlation was achieved between the two methods(r=0. 997 4). Conclusion:There is statistically significant difference in the CsA concentration in whole blood respectively determined by EMIT and HPLC. Attention should be paid to CsA monitoring by E-MIT and HPLC, and relevant adjustment should be carried out.

Objective To evaluate the clinical effectiveness of the treatment for hip osteoid osteoma by CT-guided percutaneous microwave ablation. Methods From August 2006 to January 2010, 8 patients with the osteoid osteomas of the hip were treated with CT-guided percutaneous microwave ablation, including 5 males and 3 females with an average age of 18.8 years (range, 12 to 25). The history of local pain was ranging from 2 months to 10 years, with aggravation of pain at night. The locations of the lesions contained: 4cases in the neck of femur, 2 in the lesser trochanter, 1 in the greater trochanter and 1 in the femoral intertrochanteric line. After localization of the nidus with CT, osseous access was established with a Gallini puncturatio needle. After scanning the nidus with CT, a trocar was used to obtain specimens for pathological examination. Subsequently, a microwave probe was introduced through the biopsy needle to the nidus. Microwave ablation was performed at 90 ℃ for 4 to 6 minutes. Prophylactic antibiotics were used two days postoperatively. Results Three patients were diagnosed as osteoid osteoma with the pathological confirmation after the operation, 5 cases were not diagnosed by the pathological confirmation. All the cases were followed up for 6 to 21 months. All the patients reported alleviated pain in the first 24 hours postoperation. One case with lesion in the right proximate femur retained mild pain without nonsteroidal antiinflammatory drugs 5 month after operation. The same procedure was done once more on this patient, and the outcome was good. No osteonecrosis of the femoral head and other complications were observed in all patients. Conclusion By CT-guided percutaneous microwave ablation for osteoid osteomas of hip reliably relieves pain with few complications and recurrences. The short-term efficacy is satisfactory. It is a safe and effective technique for treatment of osteoid osteoma.
