Objective To investigate the related factors of effects on distant visual acuity after photodynamic therapy (PDT) for choroidal neovascularization (CNV). Methods One hundred and thirty-five cases (135 eyes) of CNV treated with PDT were observed. The gender, preoperative distant and near visual acuity, disease course, pathogeny, area of CNV, types of CNV ascertained by fundus fluorescein angiography (FFA), and changes of CNV in FFA were recorded. Multi-factor regression analysis of visual acuity within 1 month and 3 months after PDT was performed with SPSS statistics software. Results The distant visual acuity within 1 month postoperatively was related to the preoperative distant visual acuity, the area of CNV and the changes in the FFA(P=0.000,0.030,0.062), and 3 months after PDT, it was related to the distant and near visual acuity preoperatively and the changes in the FFA(P=0.000,0.054,0.034). The condition of distant visual acuity within 1 month postoperatively was related to the FFA type of CNV and the disease course(P =0.018,0.08). Conclusion The smaller the area of CNV is, the better postoperative distant visual acuity would be. The proportion of improvement of visual acuity is relatively higher in patients with classic CNV. Early treatment for the patients with the indicatio may improve the visual acuity effectively.

Objective To investigate the feasibility of labeling iris pigment epithelial(IPE)cells of rabbits with 5-(and 6-)carboxyfluorescein diacetate succinimidyl ester(CFSE). Methods Enzyme-assisted microdissection was used to isolate the cultured rabbit′s IPE cells.The third or forth subcultured IPE cells were incubated with 2.5,5,10,20,and 40 ?mol/L of CFSE for 1,5,and10min respectively.The fluorescence intensity was detected by flow cytometry,and the leakage of CFSE and its dyeing were observed by fluorescence antibody labeling. Results Incubation with 20 ?mol/L CFSE under 37℃for1minute was the most optimal condition for IPE cells labeling.The coloration of IPE cells stained by CFSE lasted 4 weeks.There was no leakage of dye from labeled rabbit IPE cells to non-labeled human IPE cells in mixed culture process. Conclusion With the advantages of high rate of dyeing,long time of tracing,safety and convenience,CFSE can be used as a new method to label the rabbit′s IPE cells.

ObjectiveTo investigate the possible relationship between choroidal neovascularization (CNV) and macular choroidal watershed zones (CWZ) in patients with age-related macular degeneration (AMD). MethodsFifty-seven selected indocyanine green video angiograms (ICGA) of 57 patients (57 eyes) with AMD were evaluated, and 35 ones of the healthy fellow eyes of 35 patients with unilateral non-AMD fundus diseases were selected as age-matched control. The video angiograms were evaluated for investigating the relationship between CNV and macular CWZ. ResultsIn 57 eyes with AMD, 35 (61.4%) had macular CWZ, while in 35 control patients only 3 (8.57% ) had. The difference was significant (P

Objective To evaluate effects of neoadjuvant chemotherapy on axillary lymph node status in patients with breast cancer.Methods A total of 45 patients with stage Ⅱ or Ⅲ breast cancer treated with neoadjuvant chemotherapy followed by surgery(Combination Group) were compared with 79 patients with breast cancer treated with initial surgery only(Surgery Group) in respect of axillary lymph node status,including the total number of the lymph nodes and the number of positive and negative lymph nodes,according to findings of physical examination,B-ultrasonography,and molybdenum target radiography.Results The total number of the lymph nodes and the number of positive lymph nodes were significantly less in the Combination Group(16.9?5.9 and 2.5?2.2) than in the Surgery Group(20.8?8.0 and 3.9?3.0)(t=-2.856,P=0.005;t=2.790,P=0.006),whereas the number of negative lymph nodes were 14.4?5.4 and 16.7?7.0 in the Combination Group and the Surgery Group,respectively,without statistical significance(t=-1.904,P=0.055).Four patients were found loco-regional relapse in each group during follow-up checkups for 6~19 months(mean,10 months) in 40 patients in the Combination Group and 7~21 months(mean,12 months) in 67 patients in the Surgery Group.Conclusions Total and positive axillary lymph nodes retrieved after axillary lymph node dissection decrease in number after neoadjuvant chemotherapy.

Applying the specialized Master of Public Health (MPH) degree education is one of the most important parts of our nation's medical degree system innovation. It has a positive effect on the development of health care in our country. To ensure the quality of the MPH degree, we should be more careful with course studies, do better in field and social practice, be stricter with degree dissertation rejoining, and supervise and control the process of the training.

Objective To study the relationships between cognitive impairment in patients with lacunar infarcts and quantitative CT measures and to determine the independent correlative factors of cognitive impairment. Methods Neuropsychological examination was conducted for 128 patients with acute lacunar infarct. Number, location, and volume of infarcts, cerebral atrophy index and severity of white matter lesions (WMLs) were measured and recorded. Results The number of lacunar infarcts in cognitive impairment (CI) group was significantly larger than that in cognitive normal (CN) group. Mean width of sulcus and sylvian fissure, index of frontal horn and ventricular-brain ratio (VBR) were significantly different in both groups. There were more patients with 3 grades or 4 grades WMLs in CI group (62%) than those in CN group (22%). The total volume of lacunar infarcts showed no statistically significant difference. Logistic regression analysis indicated that the number of lacunar infarcts in frontal subcortex and thalamus, the volume of infarcts in anterior periventricular white matter, width of cerebral sulcus and sylvian fissure were correlated with cognitive impairment respectively. Additionally, age and education were correlative factors of cognitive impairment in patients with lacunar infarct. Conclusion Correlative factors of cognitive impairment in patients with lacunar infarct are not merely one feature, but a combination of infarct features (number, location, and volume), cortical atrophy and host factors (age and education).

BACKGROUND:Col agen suture is made of col agen from animals, and has been widely used because it is absorbable, non-rejection and easy to produce, and convenient in use.
OBJECTIVE:To evaluate the effects of col agen suture and silk suture in wound healing after oral implant surgery.
METHODS:100 patients undergoing oral implantation were randomly assigned into col agen suture group and silk suture group. A 2-0 circular needle with absorbable col agen sutures and a 4-0 circular needle with non-absorbable silk sutures were employed for tension-free suture in the two groups. After 3, 5, 7 days of oral implantation, suture threads and wound healing were observed. The suture was removed at 14 days, and patients were reviewed at 14 days.
RESULTS AND CONCLUSION:The wound healing was better in the col agen suture group than the silk suture group at grade I (P<0.05). At 7 days postoperatively, the suture thread was mostly absorbed in the col agen group but not in the silk suture group. In addition, material alba was invisible in the col agen suture group but clear in the silk suture group. These results indicate that the col agen suture is more proper for tension-free suture than the silk suture, which is better matched to the healing time and keeps a better oral environment.

Objective To analyze patients with acute chest pain as their chief complaint in order to improve our capability of early identifying and diagnosing high-risk patients,give them proper treatment in time and avoid misdiagnosis and improper treatment. Methods The clinical data of 813 patients with chest pain as their chief complaint admitted in the emergency department and critical care medicine department in Guangdong Provincial Traditional Chinese Medicine Hospital from January to December in 2011 were retrospectively analyzed. According to the process of diagnosis and treatment formulated by the chest pain center,all the patients must immediately finish the first electrocardiograph(EEC)examination in 10 minutes and the relevant blood biochemical examinations within 30 minutes after admission. Results In accordance with the relevant examinations,the confirmed diagnoses were as follows:there were 276 cases of unstable angina,accounting for 33.95%;145 cases of stable angina,17.84%;121 cases of acute myocardial infarction,14.88%;103 cases of respiratory system disease,12.67%;78 cases of skeletal muscle disease,9.59%;46 cases of the digestive system disease,5.66% and the high-risk non cardiac chest pain(such as aortic dissection/rupture of tumor or acute pulmonary embolism)12 cases,1.48%.Seven hundred and eighty-five patients finished the first EEC examination in 10 minutes,and 147 patients completed the chest computed tomography(CT)scan within an hour. Conclusions Acute chest pain is a common symptom in emergency department.
