Objective To investigate the effect of erythropoietin(EPO)as a brain-protective factor and inflammatory cytokines in the pathogenesis of cerebral palsy(CP).Methods Serum samples from 31 CP patients,37 neonates with CP risk factors such as hypoxic-ischemic injury and/or perinatal infection,and 20 controls of neonates or children were obtained respectively.EPO,tumor necrosis factor(TNF)-α and interleukin(IL)-6 levels were measured with the enzyme-linked immunosorbent assay double sandwich method(ABC-ELISA).Results The serum EPO level of neonatal patients was higher than that of controls or CP group(P<0.01),but there was no significant difference between CP group and controls.The serum TNF-α and IL-6 levels of CP and neonatal patients were higher than that in controls(P<0.01).The serum TNF-α level of CP group was higher than that of neonatal patients(P<0.05).There was no significant difference between CP group and neonatal patients in serum IL-6 level.Conclusion The inflammatory responses mediated by proinflammatory cytokines may play a role in the pathogenesis of cerebral palsy.

OBJECTIVESTo evaluate the feasibility and safety of video-assisted thoracoscopic surgery (VATS), and to compare surgical results of VATS with standard median sternotomy (MS) and other minimal invasive approaches through various small incisions (SI).

METHODSTotally 111 patients underwent surgery for thymic disorders (maximun diameter ≤ 5 cm, clinical stage I-II for thymic tumors) during March 2010 to June 2012 was retrospectively reviewed. There were 46 male and 65 female patients with a mean age of (51 ± 15) years.Resection via VATS was carried out in 47 patients, via SI in 26 patients, and via MS in 38 patients. Demographic characteristics, operation time, number and cause of conversion, blood loss during operation, duration and amount of chest tube drainage, transfusion, morbidity, and length of hospital stay (LHS) were compared between the three groups.

RESULTSOf the 111 patients, 79 patients had thymic epithelia tumors (stage I 32 patients, stage II 39 patients, stage III 8 patients), 31 patients had benign cysts and 1 patient had tuberculosis.In the VATS group, there were 3 conversions among 38 patients through right-side approach, and 4 conversions among 9 patients through left-side approach. The causes for conversion included dense pleura adhesion, invasion of tumor into adjacent structures (pericardium, lung, or great vessels), and injury of the left inominate vein. There was no significant difference in operative time, blood loss or transfusion during operation, duration or amount of postoperative chest tube drainage among the 3 groups (P > 0.05). Average LHS was significantly shorter in the VATS group (5.7 ± 1.7) days than in the SI group (7.5 ± 2.2) days and the MS group (8.2 ± 1.9) days (F = 3.759, P = 0.002). Total thymectomy was performed in 74 patients, 25 patients (53.2%, 25/47) in VATS group, 11 patients (42.3%, 11/26) in SI group, and 38 patients (100%, 38/38) in MS group. The reset of the patients received tumor resection and partial thymectomy. Among all the subgroups, LHS was the shortest in VATS total thymectomy patients (5.0 ± 1.4) days (F = 5.844, P = 0.001). There was no perioperative mortality. The only major morbidity was a postoperative bleeding necessitating reintervention in SI group.

CONCLUSIONSVATS for benign thymic lesions and early-stage thymic tumors is safe and feasible.It is associated with shorter hospital stay compared with other minimal invasive approaches or standard sternotomy.

OBJECTIVEA method for determined oxygen permeability (Dk) of finished soft contact lens.

METHODSOxygen permeability(Dk) of 10 group finished soft contact lens was determined by polarographic method, and the values were linearly calibrated using the measured and established Dk values of the specified reference materials.

RESULTSOnly one Dk value fell outside of the requirement of GB 11417.3-2012 tolerance for Dk (± 20%).

CONCLUSIONIt is great practicability when determined the oxygen permeability (Dk) of finished soft contact lens by polarographic method which were linearly calibrated using the measured and established Dk values of the specified equal thickness reference materials without the measured lens customized 4 different thickness.

AlM:To investigate the prevalence and related high risk factors of retinal vessels disease of native Tibetan among the aged 40 and above in Maqin county, Qinghai province, China.
METHODS:The cluster sampling method was used to investigate the visual acuity and retinal vessel diseases of the native Tibetan among the aged 40 and above in Maqin county.
RESULTS:Totally 2 511 individuals were underwent the survey, among them, 29 cases (37 eyes) were of retinal vessel diseases, the prevalence was 1. 15%, 21 cases (23 eyes) were retinal vein obstruction (0. 84%), 5 cases (10 eyes) were diabetic retinopathy ( 0. 20%), 3 cases ( 4 eyes) were retinal vasculitis (0. 12%). The blindness and low vision of retinal vessels disease were 23 eyes (0. 92%).
CONCLUSlON:All the hypertension, hyperglycemia, erythrocytosis, high altitude and weight are the high risk factors of retinal vessel diseases which are the main eyes fundus disease could grow blind.

Induced pluripotent stem cells (iPSCs) can be propagated indefinitely, while maintaining the capacity to differentiate into all cell types in the body except for the extra-embryonic tissues. This iPSC technology not only represents a new way to use individual-specific stem cells for regenerative medicine but also constitutes a novel method to obtain large numbers of disease-specific cells for biomedical research. However, the low efficiency of reprogramming and genomic integration of oncogenes and viral vectors limit the potential application of iPSCs. Chemical-induced reprogramming offers a novel approach to generating iPSCs. In this study, a new combination of small-molecule compounds (SMs) (sodium butyrate, A-83-01, CHIR99021, Y-27632) under conditions of transient folate deprivation was used to generate iPSC. It was found that transient folate deprivation combined with SMs was sufficient to permit reprogramming from mouse embryonic fibroblasts (MEFs) in the presence of transcription factors, Oct4 and Klf4, within 25 days, replacing Sox2 and c-Myc, and accelerated the generation of mouse iPSCs. The resulting cell lines resembled mouse embryonic stem (ES) cells with respect to proliferation rate, morphology, pluripotency-associated markers and gene expressions. Deprivation of folic acid, combined with treating MEFs with SMs, can improve the inducing efficiency of iPSCs and reduce their carcinogenicity and the use of exogenous reprogramming factors.
