Bacterial cellulose (BC) is a natural polymer that has bioactivity, biodegradability and biocompatibility. It displays unique physical, chemical and mechanical properties including high crystallinity, high water holding capacity, nanofibre-network structure, high tensile strength and elastic modulus. Due to its unusual material properties, BC has recently become a kind of attractive biomedical material in the international research.Describes BC's properties, study history and its applications as biomedical materials, especially gives emphasis to introduce the applications of BC on scaffold tissue engineering, artificial blood vessels, artificial skin and the treatment of skin wound, as well as the present study status.

Objective To explore the molecular mechanism of hypophrenia induced by Down syndrome (DS).Methods Ts65Dn mice were used as DS animal model.Three female mice and three male mice of three to twelve weeks old were mated.Among the 17 first-generation mice alive,five mice remained Ts65Dn trisomy and 12 mice were normal.Five Ts65Dn mice and five normal mice were selected randomly as Ts65Dn group and control group,and bred till 16 to 18 weeks old for experiments.Differential proteins in hippocampus of mice were tested by isobaric tags for relative and absolute quantitation (iTRAQ).Expressions of the differential proteins in Ts65Dn group were detected compared with those in control group.Results A total of 2805 proteins were identified in hippocampus of Ts65Dn group and control group,and significant differences were observed in the expressions of 374 proteins.Compared with those in control group,expressions of 195 proteins increased and 179 reduced in Ts65Dn group.Sorted by P value from low to high,the seven proteins with the lowest P value were uncharacterized protein C2orf47 homolog,isoform 2 of filamin A-interacting protein 1-like,zinc finger protein,isoform 1 of pericentriolar material 1 protein,SEC23 interacting protein,BAG family molecular chaperone regulator 3 and serpin H1.Conclusions Differential proteins are observed in hippocampus of Ts65Dn mice,perhaps closely correlating to neurological defects.The new technology of iTRAQ helps to screen and identify differential proteins in hippocampus.

OBJECTIVETo investigate the efficiency of Spanishneedles Herb eye drops in treating perimenopausal xerophthalmia in rabbits.
METHODTotally 36 rabbits (36 right eyes) were ovariectomized, and 2 months later divided into three groups: the experimental group (group A, n = 12) given Spanishneedles Herb eye drops, the control group (group B, n = 12) given PBS and the model group (group C, n = 12) given no drug. The Schirmer I test (SIT), fluorescent (FL), total tear protein, diastase activity, lactoferrin and lysozyme contents and confocal scanning microscopy were performed at before the treatment and at 1 w, 2 w, 1 mo, 2 mo after the treatment.
RESULTBefore the treatment, There was no significant difference in SIT, FL, total tear protein, lysozyme, lactoferrin and amylase activity between two groups. Two months later after the treatment, both the group B and the group A showed differences degrees of changes in SIT, FL, total tear protein, lysozyme, lactoferrin and amylase activity compared with that before the treatment, with statistical differences (P < 0.05); At each time point, both groups revealed statistical differences in SIT, FL, total tear protein, lysozyme, lactoferrin and amylase activity (1 < 0.05). Two months later alter the treatment, densities of basal epithelial cells and inflammatory cells in the group A were (4 122 ±416) cells/mm2 and (339 ± 131) cells/mm2, while that in the group B were (3 343 ± 424) cells/mm2 and (49 ± 17) cells/mm2, with statistical differences between them (P < 0.05).
CONCLUSIONSpanishneedles Herb eye drops could effectively treat perimenopausal xerophthalmia in rabbit caused by sex hormones decline.

267 newly-diagnosed patients with type 2 diabetes were divided into normoalbuminuria group [group N-UAlb, urinary albumin to creatinine ratio (UACR)<30 mg/g, n=103], microalbuminuria group(group M-UAlb, UACR 30~300 mg/g, n=88 ) , and macroalbuminuria group ( group L-UAlb, UACR>300 mg/g, n=76). The control group(group NC) consisted of 114 healthy individuals. Serum betatrophin, adiponectin(APN), and interleukin-1β( IL-1β) levels were determined with ELISA methods and the parameters of body mass index (BMI), estimated glomerular filtration rate(eGFR), HbA1C, fasting plasma glucose(FPG), OGTT 2h plasma glucose(2hPG), fasting insulin(FINS), OGTT 2h postprandial insulin(2hPINS), fasting C-peptide(FCP), homeostasis model assessment insulin resistant index(HOMA-IR), and blood lipid were collected. Compared with group NC, the serum betatrophin levels in patients with type 2 diabetes were obviously increased. In patients with type 2 diabetes, betatrophin levels increased along with the increase of UACR and there were significant differences in betatrophin among the three groups(P<0. 01). Betatrophin positively correlated with UACR, HbA1C, FPG, 2hPG, FINS, 2hPINS, HOMA-IR, TC, LDL-C, and TG( r were 0. 785, 0. 225, 0. 136, 0. 241, 0. 386, 0. 223, 0. 411, 0.216,0.193,and0.298,allP<0.05),and betatrophin were also positively correlated with APN and IL-1β(rwere 0. 643 and 0. 710, both P<0. 01). Stepwise multiple regression analysis showed that UACR, HbA1C, FINS, and TG were independent relevant factors affecting betatrophin levels.

Objective To explore students nurses′acceptance of case-based group assessment. Method A total of 100 student nurses participated in the survey by a self-designed questionnaire to evaluate the perception and acceptance of the student nurses. Results The score on the acceptance of case-based group assessment was (2.44 ± 0.46). The items with higher acceptance included teamwork spirit, clinical reasoning and decision-making ability, and the items with lower acceptance were improving of nurse-patient communication and the nursing skills. Conclusions The student nurses have a good acceptance of the case-based group assessment and think this assessment method can contribute to development of teamwork spirit and competency of clinical reasoning and decision-making. On the other hand, they suggest we should strengthen the ability in nurse-patient communication and optimize the links in ability assessment.

Objective To investigate the relationship between HIF-1αand bevacizumab resistant in o-vary cancer,and explore the influence on ovary cancer cell by HIF-1α.Methods The correlation was analyzed between HIF-1αexpression and clinicopathological parameters using immunohistochemistry in 62 patients with ovarian cancer.In addition,the expression of HIF-1αand VEGF were evaluated by real time PCR or Western Blot in SKOV3 and ES-2 cell under CoCl 2 treatment.Results HIF-1αwas overexpressed in cancer tissue, and its high levels were related to CA125(P=0.027)and resistant to bevacizumab(P<0.001).Moreover,CoCl2 could induce high expressions of HIF-1αand VEGF,when compared to normal condition.Conclusion Our findings suggest that HIF-1αis associated with resistant to bevacizumab.It is more chemotherapeutic sensitivity when combined with bevacizumab and HIF-1αantibody.
