Abstract?AlM: To investigate the effect of zebularine ( Zeb ) loaded Poly ( ethylene glycol ) - block - poly ( ε -caprolactone) methyl ether ( MePEG-PCL) nanoparticles ( NPs) on the viability, attachment, and apoptosis of in vitro cultured lens epithelial cells ( LECs) .?METHODS: In vitro cultured infant human lens tissue HLE B-3 immortalized cells were distributed randomly divided into six groups. Each group was administered with free Zeb 50μmol/L ( ZebF1 group ) , 100μmol/L ( ZebF2 group) , Zeb -loaded MePEG-PCL NPs 50μmol/L ( ZebNP1 group) , Zeb -loaded MePEG-PCL NPs 100μmol/L ( ZebNP2 group) , MePEG-PCL empty NPs( NPs group) or blank medium (group C) respectively. A tetrazolium dye assay ( MTT) test and modified MTT test were performed to determine cell viability and cell attachment. DNA ladder was used to detect the cell apoptosis.?RESULTS: Determined by MTT colorimetric method:Cell proliferation rate of LECs were suppressed by all Zeb administration groups in a concentration-time dependent manner (P<0. 05). Compared with the free Zeb groups, the viability of LECs were suppressed more effectively by the same dose of Zeb loaded MePEG-PCL NPs after 24, 48, 96h ( P < 0. 05 ). Determined by improved MTT colorimetric method: The attachment of LECs were decreased in all Zeb administration groups, Zeb loaded MePEG-PCL NPs had better effect on suppressing the attachment of LECs than the free Zeb groups with same dose (P<0. 05). The DNA ladder confirmed that after administration of 96h, group C, NPs group and ZebF1 group showed no DNA fragment, however the DNA fragment were performed in ZebF2, ZebNP1, ZebNP2 groups and displays the trend of ZebNP2> ZebNP1>ZebF2 (P<0. 05).?CONCLUSlON: Zeb loaded MePEG-PCL NPs had better effect on suppressing the viability and attachment of in vitro cultured LECs than the free Zeb groups , as well as enhancing the apoptosis.

AlM:To observe the effects of double incision combined surgery of single - stab trabeculectomy and phacoemulsification.
METHODS: Totally 28 cases ( 30 eyes ) with glaucoma and cataract undertook the modified combined surgery of single - stab trabeculectomy and phacoemulsification. After traditional phacoemulsification, cut the bulbar conjunctiva and Tenons capsule from the 11 o'clock to 1 o'clock, then puncture into the anterior chamber in 2mm behind the corneal limbus with 3mm tunnel knife, shaping a 3mm wide, 1/3-1/4 thickness scleral tunnel. Getting into the trabecular tunnel, bite off 3 pieces of trabecular tissue about 1mm × 1mm size. The changes in the imtraocular pressure ( lOP ) and the visual acuity before and after the surgery as well as filtering bleb ( OCT confirmed) and complications were carefully observed in 3-6mo postoperatively.
RESULTS: The postoperative visual acuity in 1wk postoperatively less than 0. 1 was found in 3 eyes, from 0. 1 to 0. 3 was found in 6 eyes,from 0. 3 to 0. 6 in 13 eyes, from 0. 6 to 0. 8 in 8 eyes. One eye had malignant glaucoma, and 8 eyes had cornea edema and slightly fibrin exudation in the pupil area; ln all cases maintained function conjunctival blebs of filtering, OCT confirmed this. lOP remained normal in 28 eyes in 3-6mo follow up, lOP of 2 other eyes could be controlled by anti-glaucoma eye drops.
CONCLUSlON:Double incision combined surgery of single- stab trabeculectomy and phacoemulsification is effective and safe, reduces the postoperative complications and is worthy of promotion.

OBJECTIVETo explore the cytotoxic responses of spleen T lymphocytes (CTL) in BALB/c mice induced by recombinant HSP110-HER2/neu ICD complex.
METHODSTumor-bearing mouse model was immunized by HSP110-HER2/neu ICD complex. The IFN-γ level secreted by activated spleen T lymphocytes was detected by enzyme linked immunospot assay (ELISPOT). The corresponding CTL activity was measured by granzyme release assay.
RESULTSThe BALB/c mouse model of human mammary tumor highly expressing HER2/neu was established. HSP110-HER2/neu ICD complex immunization led to a significantly higher level of INF-γ than that in HSP110-P(789-797) immunized and HER2/neu ICD immunized mice. HSP110-HER2/neu ICD complex immunized animals also show significant CTL activity. The results of immunohistochemical staining showed that the number of blue spots in the PBS group was 4.57 ± 1.33, HSP110 group 6.83 ± 2.08, HER2/neu ICD group 16.17 ± 2.86, HSP110-P(789-797) group 43.67 ± 4.78, and SP110-HER2/neu ICD group 76.51 ± 8.17. The number of IFN-γ-secreting spleen lymphocytes in the HSP110-HER2/neu ICD group was significantly higher than that in the HSP110-P(789-797) group, and that of HSP110-P(789-797) group was significantly higher than that of HER2/neu ICD group (P < 0.01). The target cell-killing rate of the PBS group was (8.15 ± 1.27)%, HSP110 group (9.51 ± 1.51)%, HER2/neu ICD group (14.03 ± 2.45)%, HSP110-P(789-797) group (25.99 ± 3.04)% and HSP110-HER2/neu ICD group (38.15 ± 3.95)% (all P < 0.01).
CONCLUSIONSHSP110-HER2/neu ICD complex can promote the proliferation and maturation of T lymphocytes into CTLs, and might be used as anti-tumor vaccine to induce potent cytotoxic T lymophocyte immunoresponse against specific tumor cells.

OBJECTIVETo study the clinicopathological characteristics of papillary cystadenoma of the epididymis.
METHODSUsing routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.
RESULTSThe 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.
CONCLUSIONPapillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

OBJECTIVETo explore the effect of ginseng-sanqi extract (GSE) on the vascular endothelium growth factor receptor-2 (VEGFR-2), Ras and mitogen-activated protein kinase (MAPK) in VEGFR-2-Ras-MAPK signal pathway of angiogenesis in cultured human umbilical vascular endothelial cells (HUVECs).
METHODSThe protein expressions of VEGFR-2, Ras and MAPK in HUVEC and the effects of GSE (at different doses) and basic fibrin growth factor (bFGF) on them were detected by Western-Blot test.
RESULTSGSE can enhance the expression of angiogenesis signaling proteins (VEGFR-2, Ras, MAPK) to different extents, especially in the groups treated by bFGF or higher dose GSE, the levels showed significant differences to those in the blank group (P<0.05).
CONCLUSIONGSE can promote the expressions of VEGFR-2, Ras and MAPK in the angiogenesis signaling pathway, which may be the foundation of Chinese medicine for tonifying qi and activating blood circulation in promoting endothelial proliferation and angiogenesis.
