Objective　 To investigate the efficacy and security of the treatment for the with visual function in neovascular glaucoma with Ahmed glaucoma value(AGV ).Methods　Twenty-six cases (26 eyes) with visual function in neovascular glaucoma underwent AGV implantation. Results　After surgery，the follow-up periods lasted for 4 to 26 months (mean 8 months ),the visual acuity of 22 eyes (86.4%) was improved or remained the same，no case of the blindness was found. The mean intraocular pressure was between 0.8～2.8kPa in 17 eyes，and the Yate of control reaches to 65.4% , the postoperative complication included transicent hyphema, Early hypotony, obstruction of the tube tip and drop out of the plate.Conclusion　The AGV implantation treating those with visual function in neovascular glaucoma is an effective and safe method.

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

OBJECTIVETo pursue insulin and islet-transplantation replacement therapy for type 1 diabetes based on engineered human non-beta cells which secrete mature insulin.

METHODSHuman proinsulin cDNA was cloned from its genomic gene and mutated by overlap extension PCR, introducing furin consensus cleavage sequences (Arg-Xaa-Lys/Arg-Arg). An expression vector encoding a genetically modified human proinsulin cDNA was generated and transduced to Hela, 293, and L02 cells by lipofectin-mediated DNA transfection. Following G418 screening, the surviving L02 cells were selected and enriched. Insulin levels in the supernatant and cells were evaluated using radioimmunoassay and immunofluorescence staining.

RESULTSThree sites in the insulin gene were mutated simultaneously. Insulin gene modified cells were able to express insulin at different levels: 8.45 - 188.00 microIU/24 h/2.0 x 10(6) Hela cells and 159.88 - 242.14 microIU/24 h/2.0 x 10(6) 293 cells for transient expression, and 2.56 - 61.95 microIU/24 h/2.0 x 10(6) from several L02 clones screened with G418. No insulin was released by control cells. Furthermore, immunofluorescence staining confirmed that proinsulin was stored as vacuoles in the cytoplasm of L02 cells.

CONCLUSIONA correctly mutated human proinsulin cDNA was obtained successfully, transfected and expressed efficiently in non-beta cells, lending support to the study of somatic gene therapy in diabetes mellitus.

Rapid and accurate identification and effective non-drug intervention are the worldwide challenges in the field of depression. Electroencephalogram (EEG) signals contain rich quantitative markers of depression, but whole-brain EEG signals acquisition process is too complicated to be applied on a large-scale population. Based on the wearable frontal lobe EEG monitoring device developed by the authors' laboratory, this study discussed the application of wearable EEG signal in depression recognition and intervention. The technical principle of wearable EEG signals monitoring device and the commonly used wearable EEG devices were introduced. Key technologies for wearable EEG signals-based depression recognition and the existing technical limitations were reviewed and discussed. Finally, a closed-loop brain-computer music interface system for personalized depression intervention was proposed, and the technical challenges were further discussed. This review paper may contribute to the transformation of relevant theories and technologies from basic research to application, and further advance the process of depression screening and personalized intervention.
