OBJECTIVETo observe the efficacy difference in the treatment of breast hyperplasia between the combined therapy of auricular point sticking and Xiaopijian and the simple application of Xiaopijian.

METHODSNinety-one patients were randomized into an observation group (46 cases) and a control group (45 cases). In the observation group, the sticking therapy on the auricular points was applied in combination with the oral medication of Chinese herbal medicine, Xiaopijian. Auricular points included Ruxian, Neifenmi (CO18), Luanchan, Shenmen (TF4), Gan (CO2), Pi (CO13). The auricular point sticking therapy was applied once a week on the auricular points of one side alternatively. Xiaopijian was the self-prepared decoction. The main ingredients are radix bupleuri Bupleurum chinense, spica prunellae prunella vulgaris and radix peoniae alba Paeonia lactiflora, 30 mL each time, three times a day. In the control group, Xiaopijian was simply prescribed for oral administration, 30 mL each time, 3 times a day. The treatment was discontinued during menstruation in the two groups. The menstrual cycle of one month made one session of treatment. The treatments for 3 sessions were observed. The scores of symptoms and physical signs, including the degree of breast pain, hardness and size of breast masses as well as the scores of general and supplementary symptoms were compared before and after treatment in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTSAfter treatment, the scores of symptoms and physical signs were reduced apparently as compared with those before treatment in the patients of the two groups (both P<0. 05). The score reduction in the observation group was much more than that in the control group (11.02±1. 78 vs 9.82±1. 53, P<0. 05). The total effective rate was 95.7% (44/46) in the observation group, higher apparently than 80. 0% (36/45, P<0. 05).

CONCLUSIONThe combined therapy of auricular point sticking and Xiaopijian achieves the superior efficacy on breast hyperplasia as compared with the simple application of Xiaopijian.

Objective To explore the therapeutic effects of pure collagenase injection and collagenase combined with herniation injection of ozone on the treatment of lumbar disc herniation(LDH).Methods According to the principle of randomized controlled double blind, 100 patients with LDH were divided into 2 groups:pure collagenase group and combined treatment group.Changes of NRS value and Macnab score were observed and recorded at multiple time points after operation.The difference of the effect of the two kinds of operation was analyzed.Results Among the 50 patients in the simple treatment group,3 patients were lost to follow-up.Among the 50 patients in the combined treatment group,2 patients were lost to follow-up,and open surgery in 2 patients because of poor efficacy after the injection of 3 months and 6 months respectively.By analyzing the change of NRS value and Macnab score of 2 groups patients,there was no significant difference in the short-term and long-term efficacy between the 2 groups(P>0.05);The symptoms of the 2 groups were improved after operation.The curative effect was positively correlated with the recovery time, and the difference was statistically significant (P<0.05).Conclusion The curative effect of pure collagenase injection and the combined with herniation injection of ozone are both significant, and there is no significant difference in the clinical efficacy between the 2 kinds of operations.

Objective To compare the clinical value of 18F-FDG PET imaging and 99Tcm-MDP whole body bone imaging in detection of bone metastases. Methods 43 patients were undergone 18F-FDG PET and 99Tcm-MDP imaging within 2 weeks. 28 of them were with confirmed bone metastases by other examinations or follow-up and the remaining 15 were confirmed without bone metastases. The results of the 2 different modalities were analyzed. Results Among 28 patients with confirmed bone metastases, PET and MDP accurately diagnosed 26 and 27, respectively. The sensitivity of them were 92.9 %(26/28), 96.4 %(27/28), Among the remaining 19 cases without bone metastases, PET and MDP correctly gave 14 and 8 negative results, respectively. The specificity of them were 93.3 %(14/15), 53.3 %(8/15), and accuracy of them were 93.0 %(40/43), 81.4 %(35/43). The differences between specificities and accuracies of the two methods were significant, while no significant difference between the sensitivities of the two methods. Conclusion For the detection of bone metastases in patients with malignant tumors, 18F-FDG PET showed a similar sensitivity but better specificity and accuracy compared with 99Tcm-MDP bone scan. For patients with suspected bone metastases, negative finding or single hot spot in 99Tcm-MDP imaging, 18F-FDG PET imaging was recommend as a further and complementary assessment of bone metastases.

Objective To observe whether bone marrow mesenchymal stem cells (MSCs) can promote the repair of IgA nephropathy and to explore its possible mechanism. Methods Sprague-Dawley rats were randomly divided into three groups which were MSCs injection group, normal saline(NS) infusion group and healthy control group. IgA nephropathy model was established by the improving method with BSA +SEB +CCl4 in former two groups. MSCs of SD rats were continuously cultured in vitro and identified with specific surface antigens by flow cytometry and osteogenic and adipogenic differentiation. MSCs were labeled with bromodeoxyuridine (BrdU) in vitro before transplanted. At 1st and 4th week after MSCs injection, the changes of body weight, urine protein, renal function, histopathology and IgA immunofluorescence were observed. MCP-1, TGF-β1 in urine were detected by ELISA. The expression of MCP-1, TGF-β1 in kidney were examined by RT-PCR. The cytokines and BrdU labeled MSCs were detected by immunohistochemistry to observe the disposition in kidney. Results At the end of the first week of MSCs transplantation, MSCs group urine protein (36.86±4.78) mg/24 h, serum creatinine (53.50±6.28) μmol/L, and the NS group urine protein (66.98±5.86) mg/24 h, serum creatinine (82.50±8.36) μmol/L, the differences between two groups were significant (P<0.05). At the same time, the content of MCP-1, TGF-β1 in urine and expression in renal tissue of MSCs group were obviously less than those of NS group (P <0.05). At the end of the 4th week, the body weight, histopatholngy, IgA immunofluorescence of MSCs group were remarkably improved as compared with those of NS group. The content of MCP-1, TGF-β1 in urine and expression in renal tissue, and renal pathological change in MSCs group had no significant differences as compared with those of healthy control group. As the time passed, the disposition of BrdU-labeled MSCs in kidney was taper. Conclusions MSCs injection contributes to renal repair in rat IgA nephropathy. The mechanism may partly depend on adjusting the excretion of cytokines in renal microenvironment and/or other functions rather than completely depend on their differentiation to renal cells.
