?AlM:To evaluate and observe the efficacy of silicon oil ( SO ) , perfluoropropane ( C3 F8 ) and balanced salt solution ( BSS ) that can be used as tamponade during vitrectomy to treat proliferative diabetic retinopathy ( PDR) complicated with vitreous hemorrhage ( VH) .
?METHODS: Studied retrospectively on 74 eyes of 60 patients who underwent vitrectomy surgery with diabetic vitreous hemorrhage in our hospital during June 2008 and June 2014. Based on repeated prior examines on fundus details and the vitrectomy tamponades were chosen. All the patients had been followed up at least 3mo. Depending on different tamponades, the paitents were nonrandomized in three groups and contrasted as visual acuity, intraocular pressure ( lOP ) and complications respectively.
?RESULTS: There was statistically significant difference among these three groups in preoperative eyesight ( P<0. 05 ). Moreover, the preoperative eyesight was statistically different between SO and BSS (P<0. 05), and difference for the rest being not remarkable(P>0. 05). The difference being statistically difference in the postoperative vision among these three groups ( P <0. 05). The further analysis showed that the paired-comparisons were statistically significant difference between SO and BSS ( P<0. 05 ), while the rest two groups of comparison were non-respectively(P>0. 05). The preoperative visual function was in contrast to the postoperative (P<0. 05). The lOP before surgery was not statistically significant difference(P>0. 05). However,the difference among three groups being statistically in the postoperative vision(P<0. 05), in addition,the difference existed in each group through pairwise comparison ( P<0. 05) . The occurence rate of complications after surgery in this survey was 47%, the SO group was 50%, the C3 F8 was 56%, the BSS group was 44%.
? CONCLUSlON: Vitrectomy is a safe and effective treatment that can help patients who have diabetic vitreous hemorrhage obtain better visual improvement. Because of the physicochemical properties and different conditions, there still has complications after surgery.

Objective To investigate the distribution of T follicular helper(Tfh)cell subsets in hepa-titis B patients at different immune stages and to clarify the relationships between the level of CXCL13 and the distribution of Tfh cell subsets. Methods Flow cytometry analysis was performed to detect the distribution of Tfh cells. Enzyme-linked immunosorbent assay(ELISA)was performed to measure the levels of CXCL13 in ser-um samples collected from hepatitis B patients. RT-PCR and Western blot assay were used to analyze the expres-sion of CXCL13 in HepG2 and HepG2. 2. 1. 5 cells. Results The percentages of Tfh1 cells were significantly up-regulated at the immune activation(IA)stage,while those of Tfh2 cells were significantly raised at the im-mune tolerance(IT)stage. The percentages of Tfh17 cells in patients at the stage of IT were similar to those in patients at the stage of IA,but were higher than those in responders with HBsAg seroconversion(RP)or healthy controls(HC). The expression of CXCL13 was positively correlated with the percentage of Tfh2 cells. More over,hepatitis B virus(HBV)enhanced the expression of CXCL13 at both transcriptional and translational lev-els. Conclusion HBV might up-regulate the percentage of Tfh2 cells through promoting the expression of CXCL13,which resulted in the induction of immune tolerance. Elucidating the functions of Tfh1,Tfh2 and Tfh17 cells and understanding the type conversion mechanism among the three subsets are important for further researches on HBV-induced immunosuppression.

Purpose To evaluate the clinical and pathological features of extramammary Paget’ s disease ( EMPD) and to investigate the related prognostic factors. Methods The clinical and pathological data of 30 patients with EMPD were reviewed retrospectively. The HE slides in the file were rechecked. Immunohistochemical stains were performed on archival paraffin-embedded sections with En-Vision method in 20 cases. Follow-up data were recorded. The relationship between the clinicopathological parameters and prognosis was statistically analyzed. Results Among the 30 patients, there were 26 males and 4 females, aged from 53 to 88 years with median age 70. Macroscopically, typical presentations of EMPD were eczematoid lesions. Microscopically, Paget’s cells were distributed sin-gly or in groups ( as glandular or nests patterns) within the epidermis. Immunohistochemical stains showed that Paget’ s cells were pos-itive for CK7, and negative for CK5/6 and p63. Follow-up data were available in 23 cases, 8 cases recurred resection, among them, 6 patients had positive resected margin and 4 died. The recurrent rate and mortality between the groups of dermal invasion and no der-mal invasion (P<0. 01 and P<0. 05), the groups of lymphatic metastasis and no lymphatic metastasis (P<0. 01), and the groups of positive and negative resected margin (P<0. 01 and P<0. 05) were statistically different. There were no statistically different with age and extent of lesion (P>0. 05). Conclusions CK7 is a sensitive and specific marker of Paget’s cells. Dermal invasion, lymphatic metastasis and positive resected margin are poor prognostic factors in EMPD.

The present paper proposed a central-driven structure of upper limb rehabilitation robot in order to reduce the volume of the robotic arm in the structure, and also to reduce the influence of motor noise, radiation and other adverse factors on upper limb dysfunction patient. The forward and inverse kinematics equations have been obtained with using the Denavit-Hartenberg (D-H) parameter method. The motion simulation has been done to obtain the angle-time curve of each joint and the position-time curve of handle under setting rehabilitation path by using Solid Works software. Experimental results showed that the rationality with the central-driven structure design had been verified by the fact that the handle could move under setting rehabilitation path. The effectiveness of kinematics equations had been proved, and the error was less than 3° by comparing the angle-time curves obtained from calculation with those from motion simulation.
