OBJECTIVETo observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients.
METHODSForty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM.
RESULTSCompared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01).
CONCLUSIONCCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

OBJECTIVETo evaluate breast reconstruction with a combined skin flap of the deep inferior epigastric perforator (DIEP) and the transverse rectus abdominis musculocutaneous (TRAM).
METHODSThe DIEP and TRAM united flap was elevated with the vessel pedicle of the deep inferior epigastric perforator on the affected side and the rectus abdominis muscle pedicle on the intact side. The reconstructive breast was shaped after the deep inferior epigastric vessels were anastomosed to the internal mammary vessels or the thoracodorsal vessels ipsilaterally.
RESULTSWe have used the DIEP and TRAM united flaps for breast reconstruction in 17 cases. All of the flaps survived, and the reconstructed breasts were well-shaped with the follow-up of 6-18 months.
CONCLUSIONSThe DIEP and TRAM united flap possesses of advantages such as rich blood supply, abundant tissue volume and easy shaping. It is especially applicable to the cases who have large chest defect and need large volume tissue.

OBJECTIVETo investigate the technique of repeated operation for removement of polyacrylamide hydrogel from breast.
METHODS17 cases after uncomplete removement of PHG were reoperated through inferior periareolar incision. The PHG and affected denatured muscle and gland tissue were removed.
RESULTSPreoperative MRI or CT showed PHG distributed diffusely in muscle and gland. There was only minimal residual PHG after operation. Histological examination showed PHG distributed in the denatured and proliferative fibrous tissue, including giant cells, many neutrophilic cells infiltration, and foreign body granuloma. The symptoms, such as intramammary pump or nodule, chest and back pain, infection, were relieved after operation.
CONCLUSIONSBlinded suction technique can not remove PHG completely and can also result in malposition of PHG and make the tissue denaturation worse. We suggest open approach to remove the PHG and denatured tissue completely through periareolar incision.

OBJECTIVETo detect the self-assembly morphology of sodium hyaluronate injection on mica using atomic force microscopy(AFM).
METHODSAtomic force microscopy with nanometer resolution was used to observe the self-assembly morphology of different concentrations of sodium hyaluronate injection on mica at room temperature.
RESULTSThe self-assembly morphology of 0.001, 0.01, and 0.1 mg/ml sodium hyaluronate injection on mica featured piebald, reticular and dendritic structures, respectively. At 1 and 5 mg/ml, sodium hyaluronate injection displayed bacilliform and spherical structures on mica, respectively; the diameter and height of the particles of 5 mg/ml sodium hyaluronate was 197.97±78.48 nm and 30.79±18.67 nm, significantly greater than those of 0.1 mg/ml sodium hyaluronate injection (49.52±11.93 nm and 5.37±1.59 nm, respectively, P<0.05).
CONCLUSIONThe self-assembly morphology of sodium hyaluronate injection on mica varies with its concentration. The piebald and reticular structure may facilitate the function of sodium hyaluronate, and the dendritic feature resembles the representative model of diffusion-limited aggregation (DLA).

A new species of Alternaria causing leaf spots on the rubber tree (Hevea brasiliensis) in Yunnan, China, was isolated, examined, and illustrated. Morphologically, it belongs to the section Porri of Alternaria, which produces relatively large conidia and a simple or branched, filamentous long beak. It is, however, characterized by conidiophores gradually enlarging near the apex into a clavate conidiogenous cell and long ellipsoid to obclavate, smooth-walled conidia with a long filamentous beak. Molecular phylogenetic analyses based on ITS rDNA, GAPDH, and TEF1-alpha sequences demonstrate that the phytopathogen falls in the clade of the section Porri, being most closely related to A. sidae, A. sennae, A. deseriticola, A. cyamopsidis, A. rostellata, A. nitrimali, A. crassa, and A. thunbergiae.

OBJECTIVETo explore the effects of rat bone mesenchymal stem cell (BMSC) transplantation on retinal neovascularization, and to observe the changes of hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factors (VEGF) in rats with oxygen-induced retinopathy (OIR).
METHODSSeventy-two seven-day-old Sprague-Dawley rats were randomly divided into three groups: normal control (CON), model (OIR) and BMSC transplantation. In the BMSC transplantation group, BMSCs were transplanted 5 days after oxygen conditioning. The phosphate buffered saline of the same volume was injected in the CON and OIR groups. The OIR model was prerpared according to the classic hyperoxygen method. At seven days after transplantation, retinal neovascularization was examined by retinal flat-mount staining and hematoxylin eosin (HE) staining. The expression of HIF-1α and VEGF proteins was examined by immunohistochemistry staining and Western blot analysis.
RESULTSThe retinal flat-mount staining results showed that the vessels were well organized in the CON group, but the vessels were irregularly organized, and lots of nonperfusion areas were observed in the OIR group. The large vessels were a bit circuitous, the retinal vessels were relatively organized, and less nonperfusion areas were noted in the BMSC transplantation group. The HE staining results showed that many neovessels and preretinal neovascular (pre-RNC) cells were observed on the internal limiting membrane in the OIR group. There were less pre-RNC cells in the BMSC transplantation group compared with the OIR group (P<0.01). The immunohistochemistry analysis showed that more HIF-1αand VEGFcells were observed in the OIR group compared with the CON group, and less HIF-1αand VEGFcells were observed in the BMSC transplantation group compared with OIR group (P<0.05). The Western blot analysis showed the expression of HIF-1α and VEGF proteins in the OIR group was significantly higher than that in the CON group. The expression of HIF-1α and VEGF proteins in the BMSC transplantation group was lower than that in the OIR group (P<0.01).
CONCLUSIONSBMSC transplantation therapy could alleviate retinal neovascularization in OIR rats, and its mechanisms might be associated with the inhibition of the expression of HIF-1α and VEGF proteins.
