Objective To investigate the clinical features of polypoidal choroidal vasculopathy (PCV) in Chinese patients. Methods The clinical data of 71 continuous patients (142 eyes) who were diagnosed with PCV by fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) were analyzed retrospectively. Results Eleven patients (11 eyes) of 71 patients (142 eyes) were diagnosed with PCV to make up 15.49% and 7 75% of the numbers of patients and affected eyes respectivery. The patients included 7 males (63 6%) and 4 females (36 4%). The predominant location for these lesions was the macular region in 10 eyes (90 9%). Fundus examination demonstrated the reddish-orange nodular elevations in 6 eyes. ICGA revealed umbrellalike or twiglike branching vascular networks and polypoidal dilations at the vascular terminals of the branches in all patients, and feeder vassels within choroidal vascular networks were found in 8 eyes. OCT images of retinochoroidal structures showed prominent anterior protrusion of the orange subretinal mass corresponding to the polypoidal structure in the indocyanine green angiogram. An apparent discontinuity was observed in the highly reflective layer which delineates the polypoidal structure. Conclusions PCV mainly affects the male over 50 years and the eyes involved were mostly unilateral. Most of polypoidal vascular lesions are present in the macular area.

ObjectiveTo study the treatment and prognosis of the breast phyllodes tumors.MethodsKG1Clinical data, and the results of follow-up in 203 cases of breast phyllodes tumors were analyzed using Logistic analysis and Cox regression in SPSS statistic software.ResultWT5”BZLocal recurrence and tumor mortality were in direct proportion to the pathologic grade of the tumor. There was a direct proportion between local recurrence and tumor infiltration; and between tumor caused-mortality and tumor mitosis and necrosis.Mitotic activity and tumor necrosis were the independent prognostic factors. After surgical resection 21 1% of patients with benign tumor, 45 2% of patients with borderline tumor, 64 3% of patients with malignant tumor suffered recurrence. The 5-year survival rate was 100% in patients with benign phyllodes tumor, 92 0% with borderline tumor, and 33 3% with malignance.KG2Conclusion Local excision is not the appropriate treatment for phyllodes tumor. Patients with benign or borderline phyllodes tumor should undergo wide local excision including a margin of uninvolved tissue, and that with local recurrent borderline and malignant phyllodes tumor receive mastectomy.

Objective To investigate the relationship between serum secreted frizzled-related protein 4 (SFRP4) and the first-phase of glucose-stimulated insulin secretion from pancreatic β cell under different glucose tolerance statuses. Methods Fifty-six patients with newly diagnosed type 2 diabetes mellitus ( T2DM group), 52 patients with impaired glucose tolerance (IGT group), and 42 subjects with normal glucose tolerance (NGT group) underwent intravenous glucose tolerance test. Fasting serum SFRP4 and interleukin ( IL)-1β were assayed by ELISA. Acute insulin response ( AIR), the area under the curve of the first-phase (0-10 min) insulin secretion (AUC), glucose disposition index(GDI), homeostasis model assessment for β cell function index(HOMA-β), and insulin resistance index(HOMA-IR) were calculated. Results (1) The levels of SFRP4 and IL-1β in T2DM group and IGT group were significantly higher than that in NGT group [(184. 38 ± 61. 34 or 141. 64 ± 40. 46 or 95. 46 ± 20. 13)ng/ ml, P<0. 01]. AIR, AUC, and GDI in T2DM group and IGT group were significantly lower than those in NGT group(P<0. 01), and these results were more significantly reduced in T2DM group compared with those in IGT group. (2) SFRP4 was negatively correlated with AIR, AUC, GDI, HOMA-β (P<0. 01), and positively correlated with fasting plasma glucose, 2 h plasma glucose after glucose loading, HbA1C , IL-1β, and high sensitive C-reactive protein(P<0. 01). (3) Multiple stepwise regression analysis showed that AUC, HOMA-IR, and serum IL-1β level were independently associated with SFRP4. Conclusion The concentration of serum SFRP4 is closely correlated with the glycolipid metabolic disorder, the first-phase of glucose-stimulated insulin secretion, and chronic low-grade inflammation. SFRP4 may be involved in the mechanism of β cell dysfunction in type 2 diabetes mellitus.

Objective:To prepare monoclonal antibody ( mAb ) against human testis-specific conserved gene ( hTSC29 ) peptides and characterize its immunological and biological features.Methods:According to bioinformatics analysis and prediction of the antigenicity, surface property, hydrophilicity and flexibility of hTSC29, a 18-amino acid residue partial peptide of hTSC29 was synthesized,then immunized the BALB/c mice for preparing antiserum.The mAb against hTSC29 was produced using the routine hybridoma technique.The properties of the mAb against hTSC29 were identified by ELISA, Western blot and immunohistochemistry staining.Results:After cell fusion and subcloning, one hybridoma cell lines secreting specific mAb against hTSC29 protein were obtaind.The Ig subclass of the mAb was IgG2b(κ).ELISA detection showed that the titer of mAbs in cultured was 1∶104.Western blot analysis proved that the mAb could specifically recognize Mr 60 000 protein in human testis total protein.The hTSC29 protein main located at circumference of spermatocyte and spermatid in human testis tissue by immunohistochemistry staining and immunofluorescence assay.Conclusion:One hybridoma cell lines which can secrete specific mAb against hTSC29 protein with high titers and specificity have been established successfully.The mAb will provide efficient tools for functional studies of hTSC29 expressed in spermatogenesis.

Objective To demonstrate the presence of adrenomedullin in the central nervous system.Methods Using immunohistochemical method (ABC) and reverse transcription-polymerase chain reaction (RT-PCR) analysis, the distribution of immunoreactive (IR-) AdM and AdM mRNA was observed in the rat and the human brain.Results Immunoreactive(IR-) AdM and AdM mRNA were detectable in almost every region of the rat brain examined, including cerebral cortex, paraventricular tissues, hypothalamus, mesencephalon, medulla oblongata and cerebellum. The levels of AdM mRNA in paraventricular tissues and medulla oblongata were higher than those in the other brain regions. AdM mRNA was also detectable in the human brain. Conclusion The present study shows that AdM is present in the central nervous system, suggesting that AdM might act as a neurotransmitter, neuromodulator or neurohormone in rats or humans.

The alpha rhythm in electroencephalograph has been associated with the mental state of the brain. The aim of the present study was to analyze the complexity of the alpha activity in depression patients by Renyi entropy (RE) under two conditions, i.e., resting with eyes closed followed by a simple mental arithmetic. The EEGs were recorded in 20 depression patients and 20 age-matched control subjects. Results showed that the alpha activity of depression patients is more complex during resting and is more regular during the mental arithmetic than that of the controls. RE analysis can well characterize the alpha activity in depression patients and could be a valuable tool to study cognitive process and also a potential effective approach for the diagnosis of depression.
