Objective To compare between conventional and endoscope-assisted greater saphenous vein harvesting and to invest if endoscope-assisted greater saphenous vein harvesting can reduce post-operative leg incision complications.Methods Minimally invasive endoscopic saphenous vein harsvesting technique has been used in 36 isolated CABG patients and this is compaired with 50 conventional saphenous vein harsvesting group. There is no significant difference in sex structure, age, hypertension, diabetes mellitum (DM), myocardial infarction (MI) et al in two groups. Results The incidence of post-operative leg complications with minimally invasive greater saphenous vein harvesting group (2.8% ) was remarkably lower than that in conventional group (28%), and the hospital-stay time was much shorter in minimally invasive group. Conclusion Endoscope-assisted saphenous vein harvesting is a effective method in reducing post-operative leg incision complications.

AIM: To investigate the difference of cognitive impairment and depression between age-related macular degeneration ( AMD ) group and the control group patients. ·METHODS: A prospective case-control study was performed from November 2014 to August 2016 in the hospital for AMD patients and sex-matched control group. The Mini-Mental State Examination ( MMSE) and the Geriatric Depression Scale ( GDS ) score of each patient were collected for statistical analyzing. ·RESULTS: There were total 84 cases ( 168 eyes ) included in the study. The difference of visual acuity between the two group was statistically significant ( F=8. 953, P=0. 004) by baseline data analyzing. There were no significant differences in MMSE scores between the two groups according to educational status ( P>0. 05 ) , while the prevalence of cognitive impairment in each group was statistically significant (x2 =4. 14, P=0. 042). The difference of GDS scores, prevalence of total and mild depression between two groups were both statistically significant (F=5. 852, P=0. 018; x2=6. 372, P=0. 012; x2 = 5. 674, P = 0. 017 ). However, there was no statistically significant difference in the prevalence of moderate to severe depression (x2=0. 672, P=0. 412). ·CONCLUSION: AMD patients have a higher prevalence of depression. Although MMSE score differences were not statistically significant in subgroup analysis by educational levels, AMD patients are more likely to have cognitive impairment overall.

Objective To investigate the expression of cyclooxygenase-2(COX-2)in breast cancers, and understand its clinical significance.Methods The immunohistochemistry was used to determine the ex- pression of COX-2 in the 40 tissues of breast cancer and 18 adjacent noncancerous mammary tissues.Results The positive expression of COX-2 was detected in 52.5% of breast cancer tissues and in 11.1% of adjacent noncancerous mammary tissues.There was a significant difference in the expression of COX-2 between breast cancer tissues and adjacent noncancerous mammary tissues(P0.05).Conclusion COX-2 was over expressed in breast cancer and correlated with metastatic lymph nodes and HER-2/neu.The expression of COX-2 may play an important role in carcinogen- esis,progression and prognosis of breast cancer.

Objective To investigate the relationship between the expression of Fascin and breast cancer prognosis. Methods Paraffin sections of breast cancer from 110 patients were investigated by immunohostochemistry with monoclonal anti-fascin antibody. Data of the Fascin expression and clinicopathological variables were analyzed for disease-free survival(DFS)and overall survival(OS)by Kaplan-miere and cox model. Results The expression of Fascin was significantly associated with ER negative,PR negative and lymph node metastasis,but not with age,HER2 status and tumor size. The patients with positive expression of Fascin had shorter disease free survival time than those without Fascin expression. Conclusion High expression of Fascin is associated with poor prognosis in breast cancer. Fascin is an independent prognostic indicator of disease-free survival time.

Objective To evaluate the value of IL-17 and IL-23 expression in response prediction of infliximab treatment in Crohn's disease (CD).Methods A total of 23 CD patients were enrolled in this study including 19 males and 4 females.Another 17 patients with colonic polyps were recruited as control group.The tissue expression of IL-17 and IL-23 in intestinal mucosa was measured by immunohistochemistry (IHC).In each specimen, IL-17 or IL-23 positive cells were counted and recorded in 10 random high power fields (HPFs).Results Infliximab was effective in sixteen patients (69.6％), while 7 patients (30.4％) did not response.The numbers of IL-17 or IL-23 positive cells were much more in responders than those in nonresponders.The median numbers of IL-17 positive cells were 26.7 (18.0, 38.6)/HPF in responders, 11.8 (7.0, 14.0)/HPF in nonresponders, 3.0 (2.0,4.0)/HPF in controls (P =0.004).The median numbers of IL-23 positive cells were 74.5(44.8, 128.6)/HPF in responders, 22.4(19.0, 38.8)/HPF in nonresponders, 3.0(2.0, 4.0)/HPF in controls (P =0.018).IL-17 or IL-23 positive mucosal cells were significantly decreased after infliximab treatment.Conclusion High expression of IL-17 and IL-23 in mucosa may predict the response to infliximab in CD patients.

BACKGROUND:The micro-ecological environment has been broken when the ocular prosthesis was inset into the conjunctival sac. The recede of self cleaning function is more conducive to the microbial growth and colonization. The cleaning of plaque biofilm on ocular prosthesis surface affects the patient's wearing comfort and quality of life. It is necessary to seek an effective cleaning method. OBJECTIVE:To compare the clearance effect of five cleaning methods on the palque biofilm on ocular prosthesis surface. METHODS: The conjunctival secretions from 84 patients who were subjected to ocular prosthesis repair were taken for bacterial culture and identification. Fifty pieces of self-curing resin and thermosetting resin artificial eyes were produced. The artificial eyes in each group were randomly divided into five groups, and were cleaned respectively with clear water, volume fraction of 75% ethanol, Boston SIMPLUS, polident and toothpaste. After the completion of the cleaning, the test piece was conducted residual biofilm culture. The clearance effects of different processing modes were evaluated using colony counting method. RESULTS AND CONCLUSION: Eighty-four specimens were submitted for inspection, of which 49 were positive. The Staphylococcusaureus separation rate was 14.29%.Staphylococcus epidermidis separation rate accounted for 13.10%. Maxwel Corynebacterium separation rate accounted for 7.14%. When water, Boston SIMPLUS and toothpaste were used for cleaning, theStaphylococcus aureus colony number in the self-curing resin group was higher than that in the thermosetting resin group (P< 0.05); when ethanol and polident were used for cleaning, there was no difference in the Staphylococcus aureus colony number between these two groups. In self-curing resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). The colony count in the ethanol treatment group was lower than that in the Boston SIMPLUS group (P < 0.05). There was no significant difference in the colony count between other groups. In thermosetting resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). There was no significant difference in the colony count between other groups. These results demonstrate that ethanol, Boston SIMPLUS, polident and toothpaste have better cleaning effects onStaphylococcus aureusbiofilms on the surface of two kinds of ocular prostheses than the clear water rinse. Overal, it is encouraged to clean the artificial eyes using polident and Boston SIMPLUS, in order to avoid the occurrence of microbial infection in the conjunctival sac after wearing ocular prosthesis.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.
