OBJECTIVETo study clinical efficacy of smoothing Gan reinforcing Shen (SGRS) method in treating poor response of diminished ovarian reserve (DOR) patients in in vitro fertilization and embryo, transfer (IVF-ET).

METHODSTotally 84 DOR patients undergoing IVF-ET were assigned to the experimental group (SGRS Chinese herbs as adjuvant therapy) and the control group according to random digit table, 42 in each group. Patients in the control group received controlled ovarian hyperstimulation (COH) and IVF-ET. Those in the experimental group additionally received basic formula of SGRS method, one dose per day. The dose and use time of recombinant follicle-stimulating hormone (r-FSH) were recorded during ovarian stimulation process. On the injection day of human chorionic gonadotropin (HCG) and serum levels of estradiol (E2) on the oocyte retrieval day were determined using chemiluminescent method. E2 contents in the follicular fluid on the oocyte retrieval day were detected using ELISA. The total number of retrieved oocytes, the number of mature oocytes in metaphase II (M II), the number of normal fertilization [with two pronucleus (2PN)], the number of portable embryos, and the number of good quality embryos were recorded. The correlation between Chinese medical adjuvant therapy and the aforesaid indices were observed. The clinical pregnancy rate and the abortion rate were finally compared between the two groups.

RESULTSThe total dose of r-FSH, the E2 level on HCG injection day, the serum E2 level on the oocyte retrieval day, the number of retrieved oocyte, the number of oocytes in M II the number of oocytes with 2PN, the number of portable embryos, and the number of good quality embryos were all positively correlated with Chinese medical adjuvant therapy (P < 0.05, P < 0.01). Compared with the control group, serum E2 levels on the HCG injection day and the oocyte retrieval day obviously increased, the number of retrieved oocytes, the number of oocytes in M II, and the number of portable embryos were increased more in the experimental group with statistical difference (P < 0.05, P < 0.01). There was no statistical significance in the clinical pregnancy rate or the abortion rate between the two groups (P > 0.05).

CONCLUSIONSGRS Chinese herbs as adjuvant therapy could improve ovarian responsiveness of DOR patients undergoing IVF-ET, increase the number of retrieved oocytes, elevate the quality of oocytes and the number of embryos.

Purpose To explore ultrasonic characteristics of complex fibroadenoma (CF) of breast and its differential diagnosis from invasive ductal carcinoma (IDC).Materials and Methods Sixty-one patients with CF and 81 patients with IDC from January 2010 to February 2016 in the Affiliated Union Hospital of Fujian Medical University were enrolled,and the CF and IDC were confirmed by pathology after operation.The preoperative sonographic findings of CF and IDC were retrospectively analyzed and compared.Results Fifty-nine cases with CF were detected by ultrasonography in 61 cases.Ultrasonic findings of 59 cases of CF showed as follows:79.7％ (47/59) of the CF cases with an aspect ratio ＜0.7;79.7％ (47/59) with blood flow signal of 0 to 1 level;72.9％ (43/59) with liquid dark area,including 67.8％ (40/59) with round or oval cystic fluid area showing local sievelike or diffused distribution;72.9％ (43/59) with irregular shape;61.0％ (36/59) with obscure boundary;61.0％ (36/59) with the largest diameter of tumor ＜2 cm;59.3％ (35/59) with calcifications,including 33.9％ (20/59) with coarse calcification,25.4％ (15/59) with microcalcification and 85.7％ (30/35) with distribution of calcified lesions along the linear high echo zone;54.2％ (32/59) with echo heterogenicity showing linear high echo and high echo in the middle and low echo.There were significant differences in the detection rates of internal regular fluid area,internal linear high echo or high echo area,and alcification distribution along the linear high echo between CF and IDC lesions (all P＜0.01).Compared with IDC,there were higher rates in CF for detecting lesions of largest diameter of tumor ＜2 cm,more regular shape,more clear border,poorer blood flow signal (P＜0.05),but there were lower rates in CF for detecting axillary lymph node enlargement,lesions with edge or spiculation and hyperechoic halo (P＜0.01).Conclusion Color Doppler ultrasonography is of great value in the diagnosis of CF and its differential diagnosis from IDC.

BACKGROUND:There are less reports on how to successfuly build the internal spatial configuration of tissue-engineered tooth scaffolds.
OBJECTIVE:To find a way to establish a series of three-dimensional digital modes for tissue-engineered tooth scaffold, such as CAD spatial configuration and Standard Template Library (STL) files.
METHODS:In order to get three-dimensional printing format of STL files, MICRO CT data of DICOM format were input into MIMICS and GEOMAGIC softwares, creating the outline of STL files. Then CATIA V5R17 software was used to create the three-dimensional digital mode of tissue-engineered tooth. Then, the overal model of the internal scaffold was obtained by arraying at the proper coordinates. Various overal scaffold configurations could be built rapidly by varying monomer configuration. The STL files of CAD model of three-dimensional printing tissue-engineered tooth were obtained by assembling the tooth outline mode and the internal scaffold.
RESULTS AND CONCLUSION: The CAD model was constructed successfuly, and this model could be directly used for three-dimensional printing rapid prototyping system to produce tissue-engineered tooth scaffolds. These findings indicate that the three-dimensional digital mode based on reverse engineering and positive engineering can be established, which can be used to quickly build a variety of internal spatial configurations of scaffold materials required for tissue-engineered teeth.

The purpose of this study was to investigate the pharmacokinetic interaction between sunitinib and ramipril in rats. Eighteen male SD rats were divided into three groups, with each group being assigned to orally receive sunitinib, ramipril, sunitinib and ramipril, respectively, for ten days. Blood samples were collected at dif-ferent times after first-day and tenth-day administration. The concentrations of ramiprilat and sunitinib in rat plasma were determined by LC/MS/MS and the pharmacokinetic parameters were calculated and statistically analyzed. Compared with the administration of ramipril alone, after a single-dose combined administration, tmax of ramiprilat decreased significantly and t1/2 prolonged, while AUC0-∞ remained unchanged. These results indicated that the ab-sorption rate of ramiprilat increased and the elimination rate decreased, but total absorption degree was not changed. After multiple-dose administrations, CL of ramiprilat decreased and AUC0-∞ increased obviously. It sug-gested that accumulation of ramiprilat occurred in body and the drug elimination became slower. No obvious difference of sunitinib pharmacokinetic behavior was found when it was given in combination with ramipril after a single-dose administration or multiple-dose administration. Sunitinib decreased the elimination of ramiprilat after co-administration in company with drug accumulation in body after multiple-dose co-administration. The study showed that there were pharmacokinetic interactions between sunitinib and ramipril in SD rats.

Objective:To study the influence of metformin and paclitaxel in the proliferation and apoptosis of human ovarian cancer SKOV3 cells in vitro, and to clarify the synergistic effect of metformin and paclitaxel. Methods:The ovarian cancer SKOV3 cells were divided into blank control group, different concentrations (0.01, 0.50, 1.00, 5.00, 10.00mmol·L-1) of metformin groups and combined treatment groups(metformin combined with paclitaxel with different concentrations).The inhibitory rates of proliferation of SKOV3 cells after treated with different concentrations of metformin were detected by MTT method.The apoptotic rates of SKOV3 cells after treated with different concentrations of metformin were measured by flow cytometry.The inhibitory rates of proliferation of SKOV3 cells after treated with metformin and paclitaxel were determined by MTT method.Results:The MTT results showed that the inhibitory rates of proliferation of SKOV3 cells in different concentrations of metformin groups were increased in concentration-and timedependent manner;there were significant differences compared with blank control group (P<0.05).The flow cytometry results showed that the apoptotic rates of SKOV3 cells in different concentrations of metformin groups were increased;compared with control group, with the increasing of concentrations of metformin, the apoptotic rates of SKOV3 cells in experimental groups 48 h after treatment were increased significantly (P<0.05);the percentages of SKOV3 cells in G0/G1 phase were decreased with the increasing of metformin concentrations(P<0.05) and the percentages of SKOV3 cells in G2/M phase were increased(P<0.05).The MTT results showed that the inhibitory rate of proliferation of SKOV3 cells in 1.00 mmol·L-1 metformin+paclitaxel group was higher than that in 0.50 mmol·L-1 metformin+paclitaxel group was higher than that in 0.50 mmol·L-1 metformin+paclitaxel group(P<0.05),and the inhibitory rates of proliferation of SKOV3 cells in combined treatment groups were higher than those in paclitaxel alone groups(P<0.05).Conclusion:Metformin inhibits the proliferation of ovarian cancer SKOV3 cells through the induction of apoptosis.Metformin can enhance the cell proliferation inhibition of paclitaxel on ovarian cancer SKOV3 cells.The combination of metformin and paclitaxel has a synergistic reaction on SKOV3 cells.
