To construct a steady canine abdominal aortic aneurysm model to study endovascular graft exclusion, fifteen hybrid canines(averaged 13 5kg) accepted bovine jugular vein segments replacement at infra kidney abdominal aortic to construct aneurysms, while lumbar arteries were reserved. All the fifteen aneurysms had satisfactory figures as clinical patterns. The aneurysm parameters were proximal neck diameter(6 0?0 8)mm, distal neck diameter(5 7?0 6)mm, aneurysm sac diameter(22 7?13 3)mm, length(36 1?17 9)mm. It is concluded that the designation of this model is suitable for endovascular graft exclusion,and can be applicated in many procedures.

Objective To explore the changes and significances of serum leptin and interleukin-1?(IL-1?)before and after treatment with risperidone in children with schizophrenics.Methods Thirty-one cases with first-episode children with schizophrenia were chosen in patient group.Their body weight and height were measured before and 8 weeks after treatment with risperidone to calculate the body mass index(BMI),and their fasting serum leptin and IL-1? were assayed radio-immunity method.Thirty-one healthy controls were measured at the same time.Results BMI and the level of serum leptin in patients of post-treatment increased significantly compared with those of pre-treatment(all P

To investigate the epidemic and evolutionary trends of enterovirus (EV) in the external environment of Yunnan Province, China, molecular typing was performed on 4 EV strains that were isolated from environmental sewage in Yunnan. The VP1 region of isolates was amplified by RT-PCR using universal enterovirus primers, and the amplified VP1 region was sequenced for GenBank BLAST search and genotype analysis. The 4 EV strains were identified as ECHO7. Their nucleotide and amino acid homologies with the VP1 sequences of 68 ECHO7 strains retrieved from GenBank were measured by Mega software analysis. Our findings showed that ECHO7 strains from environmental sewage and population samples were in different evolutionary branches. These strains showed typical geographical and temporal differences; In addition, there were different transmission chains at the same time and in the same area. ECHO7 strains isolated from sewage water and patients with acute flaccid paralysis during the same period in Yunnan belonged to different clusters and evolved at different speeds. Special concerns are needed for this problem. Continuous molecular biological surveillance of human EV in the external environment of Yunnan will provide strong support for early warning of EV diseases.

AlM:To observe the changes of corneal endothelium after phacoemulsification cataract surgery in different types of cataract patients.
METHODS: Randomly selected age-related cataract, diabetic cataract and cataract of high myopia 30 eyes of 30 cases, respectively, in our hospital. All patients underwent phacoemulsification combined with intraocular lens implantation, corneal endothelial density and the percentage of hexagonal cells were measured by corneal endothelial cell instrument without touching before surgery and one week after surgery.
RESULTS: The difference of the preoperative corneal endothelial cell density and the percentage of hexagonal cells among three groups were not statistically significant (P>0. 05). One week after surgery, the cell density in three groups were respectively 2 496. 86 ± 298. 96/mm2 , 2 379. 51 ± 375. 13/mm2 , 2 425. 38 ± 312. 68/mm2 , the percentage of hexagonal cells were respectively ( 46. 20 ± 12. 03)%, (43. 44±13. 99)%, (44. 35±8. 13)%. Both the cell density and the percentage of hexagonal cells one week after surgery were lower than those before operation. There were significant difference in three groups ( P <0. 05). Both the measurements in diabetic cataract group and cataract of high myopia group after surgery were lower than those in age-related cataract group, the cell density and the percentage of hexagonal cells in diabetic cataract group were lower obviously compared with those in age- related cataract group and the difference was significant (P<0. 05).
CONCLUSlON:The tolerance of corneal endothelial cell to phacoemulsification cataract surgery is lower in cataract with diabetes and high myopia. Corneal endothelium should be assessed preoperatively and protected intraoperatively.

OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.

METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.

RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.

CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.

OBJECTIVETo reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.

METHODSSAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

RESULTSCompared with the control group, acupuncture increased 39 transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice, of them, 14 belonged to ionophorous protein, 8 to G protein, 8 to transmembrane signal receptor, and 9 to kinase protein. Totally 3 main cell signal pathways were involved, including G-protein-coupled receptors signal, enzyme linked receptor signal, and ion-channel mediated signal. Compared with the sham-acupuncture group, acupuncture resulted in significant increase of kinase signal protein amount. From the aspect of functions, they were dominant in regulating synapse functions relevant to cytoskeleton and secreting neurotransmitters.

CONCLUSIONThe cell biological mechanism for treating AD by acupuncture might be achieved by improving synapse functions and promoting the secretion of neurotransmitters through transmembrane signal transduction, thus improving cognitive function of AD patients.

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.
