Objective The purpose of this study is to investigate the expression of human epidermal growth factor receptor-2(HER-2)in gastric carcinoma tissue and normal gastric tissue of these patients,and its relationship with the clinical pathological characteristic,the microvessel density( MVD) and early post-operative recurrence,and to analyze the clinical significance of expression of HER-2 in gastric carcinoma,in order to lay the theoretical foundation of effective therapy for gastric carcinoma.Methods The clinical data of 398 cases of gastric cancer and 363 cases of their adjacent non tumorous gastric tissue of Liaoning Cancer Hospital from March 2012 to July 2013 were analyzed retrospectively.The expression of HER-2 gene was detected by IHC method and Fish method.The expressive rate of HER-2 in gastric carcinoma tissue and normal gastric tissue of these pa-tients were compared,and its relationship with the clinical pathological characteristic,MVD and early post opera-tive recurrence were also analyzed.Results (1)Expressive rate of HER-2 in 398 cases of gastric cancer tissue was 14.07%(56/398),which was higher than that in all the adjacent non tumorous gastric tissue presented none expression 0(0/363)(P<0.05);(2)In gastric cancer tissue of 398,the expression of HER-2 was related with Lauren type,tumor site,vessel invasion status,TNM stage,lymph node metastases(P<0.05),and it had no cor-relation with age,sex,tumor size,histological differentiation degree,growth patterns of cancer(P>0.05).Expres-sive rate of HER-2 in T4 stage was higher than( T1 +T2 +T3 ) stage,but the difference was not statistically sig-nificant( P>0.05).(3)The value of MVD in HER-2 expressive group(58.63 ±19.97)was significantly higher than those in HER-2 non expressive group(49.04 ±19.25).A positive significant correlation was found be-tween HER-2 and MVD expression using the rank correlation matrix(P<0.001,r=4.33).(4)1 year and 1.5 year of early post operative recurrence rate in HER-2 expressive group were 16.00%、38.00%,in HER-2 non expressive group were 8.81%,25.53%,the difference was not statistically significant(P>0.05).Conclusion There is excessive expression of HER -2 in gastric cancer tissue,excessive expression of HER -2 patients withgastric cancer is correlated with Lauren type,tumor location,vessel invasion status,TNM stage,lymph node metastases;it displays no correlation with age,sex,tumor size,histological differentiation degree,growth patterns ofcancer.HER -2 expression is positively associated with MVD value.Excessive expression of HER -2 is possibleto be correlative with early post operative recurrence,and it must have further follow up to confirm.

Objective To identify the condition of colostomy care in different postoperative stages among the colostomy patients. Methods This study was divided into two section. Using the self-designed questionnaire to investigate 42 postoperative colostomy patients in the first and the second year respectively after the colostomy operation. Results With the time passing by, the money which have been used in buying colostomy products increased, while, the time in the colostomy care decreased. There are no significant difference between the two time point in colostomy self-care ability. The effect factors are age and the time since colostomy in the first year; and gender, age and the time since colostomy are the factors in the second years. Conclusion Nurses should using different nursing method according to the different physical and psychological condition of colostomy patients, and then promote rehabilitation early.

Age-related macular degeneration (AMD) and cataract are the most common causes of low vision worldwide.Nowadays, there is still a controversy about whether cataract surgery should be taken in patients combined with AMD and when should the surgery be taken.The aim of this review is to assess the influence of cataract surgery on the occurrence and development of AMD, to analyze the risk factors, to explore the occasion of cataract surgery in patients with AMD, and joint with anti-vascular endothelial growth factor (VEGF) treatment, also including the development and application of intraocular lens.It helps to avoid and postpone the development and progression of macular degeneration after cataract surgery and get good visual outcome.

Total esculentosides and polysaccharides are determined and compared in roots of Phytolacca acinosa Roxb., P. americana L., P. polyandra Bat., P. zhejiongensis W.T. Ean Produced in China. Results showed that P. polyandra Bat. has the highest content of esculentosides (6.24% ), while P. acinose is most rich in polysaccharides (10.57% )

Hydrolysate of Area subcrenata (HA) was found to be effective in lowering the elevated SGPT level induced by carbon tetrachloride, thioacetamide (TAA) and pred-nisolone. In addition, HA was shown to shorten sodium pentobarbital sleeping time in both normal and carbon tetrachloride intoxicated mice. The results indicated that HA possessesa significantl protective action on liver injuries in mice.

Objective To investigate the effects of flumazenil and naloxone on scopolamine-induced impairment of spatial working memory in rats.Methods Forty pathogen-free SD rats weighing 160-200 g were randomly divided into 4 groups(n=10 each):group I control(group C);group IIscopolamine(group S);group III flumazenil+scopolamine(group SF)and group IV naloxone+scopolamine(group SN).Scopolamine 0.8 mg/kg was administered IP once a day for 3 consecutive days in group II-IV.In group SF and SN flumazenil 0.5 mg/kg and naloxone 2 mg/kg were administered IP respectively once a day for 3 consecutive days in addition to scopolamine.Thirty minutes after last IP administration,cognitive function was assessed using Y-maze.The animals were killed after cognitive function assessment and bilateral hippocampi Were isolated for determination of mAChRM1 mRNA expression(by RT-PCR)and detection of ChAT positive neurons(by immuno-histochemistry).Results Cognitive dysfunction developed in group S as compared with control group and was ameliorated in group SF and SN.The number of ChAT positive neurong and mAChRM1 mRNA expression were significantly decreased in group S compared with control group and were significantly higher in group SF and SN than in group S.Conclusion Flumazenll and naloxone can ameliorate the scopolamine-induced impairment of spatial working memory by improving cholinergic neuron function.

Six cases of Paget′s disease of bone, including 5 males and 1 female, aged (57. 7 ±11. 8) years old, were recruited. Mean duration of disease was (7. 5±6. 5) years. Clinical manifestations were bone pain and bone deformity. The lesions mainly reside in the pelvis and femur. X-ray film showed typical lesion of Paget′s disease of bone, such as impaired bone trabecular structure with coarseness and disorder, cortical thickening, medullary cavity narrowing and skeletal deformation. Bone scan revealed abnormal radionuclide concentration in the involved bone. Serum alkaline phosphatase ( ALP) in 6 patients was increased ( median 235 U/ L). 5 patients received zoledronic acid sodium intravenous infusion therapy. Bone pain was relieved obviously in 5 patients after treatment for 2-3 months. Physical activity was greatly improved, and serum ALP levels significantly decreased.

Objective To culture astrocytes of human optic nerve and establish the cell lines for further study of healing process after optic nerve trauma. [WT5”HZ]Methods [WT5”BZ]Astrocytes of infantile optic nerve were cultured by tissue inoculation or tissue digestion with 0.25% trypsin and 0.06% EDTA. The second and fourth passage cells were stained with HE and anti GFAP, S 100 protein, vimentin, and CD34 antibodies. [WT5”HZ]Results The trypsinized astrocytes of infantile optic nerve reached confluence in 7 days. The cultured cells were in polygonal shape with processes and the cytoplasm was abundant. These cells were positive in GFAP, S 100 protein and vimentin staining, and negative in CD34 staining. Conclusions Astrocytes of human optic nerve can be successfully cultured by trypsinization rather than tissue inoculation.

Objective To study the related factors and how they influence the formation of collateral circulation in patients with severe coronary arteries stenosis. Methods A total of 111 consecutive patients were catagorized into 3 groups according to their grading of collateral connections which were: CC0 (n=27), CC1 (n=45) and CC2 (n=39) respectively. Serum lipid levels were measured including total cholesterol, triglycerides, high density lipoprotein cholesterol and low density lipoprotein. All patients received UCG examination within one week after admission. Results (1)Serum lipid levels: the total cholestoral level in the CC2 group (4.23?0.71 mmol/) was lower than those of the CC0 group (4.81?0.88 mmol/L, P0.05) and the CC2 group (1.40?0.24 mmol/L, P
