Objective To investigate whether acupuncture can prevent postoperative nauseaand vomiting (PONV)in patients received breast surgery. Methods Two hundred and forty patients were randomly divided into the acupuncture group and the control group. Patients in the acupuncture group were treated at bilateral Hegu (L4) and Neiguan (P6) after surgery. Patients in the control group received no any interventions. The occurrence of postoperative nausea and vomiting, the number of complete remission and the remedial treatment were record ed. Results The incidences of nausea and vomiting in the acupuncture group were lower than those in the control group from 2 h to 6 h post-operation, with less need of remedy treatment (P < 0.05, respectively). Conclusion Acupuncture in preventing nausea and vomiting after breast surgery owns a certain value in the early postoperative (6 h) stage, with effectively reducing the occurrence of postoperative nausea and vomiting.

Objective To investigate the significance of tamoxifen in the combination chemotherapy of human multidrug-resistant bile duct carcinoma cell line (QBC939/ADM) and its mechanism. Methods The QBC939/AI)M was established, through exposure to gradually increased and the high and low alternated concentration of ADM persistently. The QBC939 and the QBC939/ADM were effected by single ADM, MMC, VDS or jointly with TAM. Drug sensitivity was measured by MTT. Growth cycle and apoptosis were performed by FCM. The level of their P-gp was detected by IHC. The content of ADM in the human cholangiocarcinoma cell line QBC939 was observed by FCM. Results The inhibitive rate of ADM, MMC, VDS to QBC939/ADM was rather lower than to QBC939. With the use of TAM, their chemotherapy effects were apparently enhanced and the apoptosis ratio increased comparably. The IHC results showed that the level of P-gp on the QBC939/ ADM was overexpressed, and the content of ADM in the QBC939/ADM group was much lower. Effected with the high content of TAM(10 μmol/L), the level of P-gp on the QBC939/ADM was decreased, with the content of ADM in the QBC939/ADM group increased comparably. TAM could both improve the chemotherapy effects of the two types of the cell, but the effect of the QBC939/ADM group was more apparent. Conclusion TAM can enhance the depressant effect of chemotherapy to both the two types of the cell, and increase the content of ADM in the QBC939/ADM group. TAM can be combined with the overexpressed P-gp.

Objective The aim of this study is to examine the effect of myoophenolate mofetil (MMF) on epithelial-myofibroblast transiation(EMT) in adenine-induced chronic renal failure (CRF) rat model and the role of vascular endothelial growth factor(VEGF) and inhibitor of differentiation (Id2 and Id3) in EMT in the rat kidney. Methods Sixty-four male Wistar rats were randomly assigned to the following groups: normal control (n=16), CRF (n=24) and MMF(n=24). CRF was induced by gastric gavage of adenine (125 mg·kg-1·d-1) to rats for eight weeks. CRF rats were treated with MMF (15 mg·kg-1·d-1) as "MMF" group. The rats were sacrificed at week 2, 4, 6 and 8, respectively.Urinary protein and serum ereatinine levels were measured, and the histopathologic degrees of interstitial fibrosis were evaluated in Massen-stained sections. Expressions of a-smooth muscle actin (α-SMA),transforming growth factor β1 (TGFβ1), VEGF and Id (Id2 and Id3) in the kidney tissue were assessed by immunohistochemistry, RT-PCR and/or Western blot methods. Results The urinary protein level in MMF group was evidently lower than that in CRF group (P<0.01), whereas no statistically significant difference was observed in serum creatinine level between the two groups. Renal interstitial fibrosis was reduced significantly with MMF treatment (P<0.01). Expression of α-SMA in MMF group was lower than that in CRF rats at week 6, 8 (P<0.01), while expression of TGFβ1 was decreased markedly at week 2, 4,6 (P<0.01). The expressions of VEGF in MMF rats were increased significantly at week 6,8 (P<0.01),and Id2,Id3 in MMF rats were increased significantly at week 4,6 (P<0.05). Conclusions MMF may ameliorate chronic renal fibrosis and EMT in adenine-induced CRF rats. This effect of MMF on EMT is probably related to upregulation of VEGF, Id2 and Id3 expressions and suppressing overexpression of TGFβ1 in renal tissue. The exact mechanism needs to be studied further.
