The aim of this study is to investigate the effect of fluoxetine (FLX) on the expressions of BDNF and Bcl-2 in the hippocampus, the amygdala and the prefrontal cortex of conditioned fear (CF) model mice. Forty eight mice were randomly divided into three groups, normal control group, CF stress group and FLX-pretreated CF group. The FLX-pretreated CF group was given FLX (10 mg x kg(-1) x d(-1)) for 7 days before CF stress. After CF stress model was established, all mice were given behavioral experiments to test whether FLX impaired or improved the auditory and contextual fear conditioning. Then mice were sacrificed. The expressions of BDNF and Bcl-2 were detected by Western blotting. The results showed that the freezing time of FLX-pretreated CF group was significantly lower than that of CF group; FLX pretreatment up-regulated the expression of Bcl-2 in the hippocampus at 1 d after CF stress (P < 0.001), but no significant differences was observed at 7 d; BDNF significantly increased in the hippocampus at 7 d (P < 0.001), but no differences at 1 d; the expressions of BDNF and Bcl-2 in the amygdala and the prefrontal cortex were of no obvious differences between CF group and FLX-pretreated CF group at 1 d or 7 d after CF stress. Parallel to these changes, pretreatment with FLX could affect histopathologic changes induced by CF stress. Furthermore, the results indicated that FLX pretreatment could protect against CF stress-induced neurological damage via the activation of BDNF and Bcl-2 in hippocampus.

The article introduces a new method for three-dimensional reproduction of edentulous dental casts, and wax occlusion rims with jaw relation by using a commercial high-speed line laser scanner and reverse engineering software and evaluates the method's accuracy in vitro. The method comprises three main steps: (i) acquisition of the three-dimensional stereolithography data of maxillary and mandibular edentulous dental casts and wax occlusion rims; (ii) acquisition of the three-dimensional stereolithography data of jaw relations; and (iii) registration of these data with the reverse engineering software and completing reconstruction. To evaluate the accuracy of this method, dental casts and wax occlusion rims of 10 edentulous patients were used. The lengths of eight lines between common anatomic landmarks were measured directly on the casts and occlusion rims by using a vernier caliper and on the three-dimensional computerized images by using the software measurement tool. The direct data were considered as the true values. The paired-samples t-test was used for statistical analysis. The mean differences between the direct and the computerized measurements were mostly less than 0.04 mm and were not significant (P>0.05). Statistical significance among 10 patients was assessed using one-way analysis of variance (P<0.05). The result showed that the 10 patients were considered statistically no significant. Therefore, accurate three-dimensional reproduction of the edentulous dental casts, wax occlusion rims, and jaw relations was achieved. The proposed method enables the visualization of occlusion from different views and would help to meet the demand for the computer-aided design of removable complete dentures.

Objective To study the effects of Hydergine on expression of N-methyl-D-aspartate receptors in hippocampus and actions of mice with ischemia-reperfusion injury.Methods 36 mice were randomly divided into model group,Hydergine group and sham-operated group. The models of ischemia-reperfusion injury were made by knotting bilateral common carotid arteries. The behavioral abnormalities were investigated by step-down test and water maze test, and the expressions of N-methyl-D-aspartate receptors in neurons of hippocampus were observed by immunohistochemistry technique. Results Compared with model group, the performance records of learning and memory in Hydergine group were better (all P

OBJECTIVETo explore the effective techniques for correction of lacrimal groove and palpebromalar groove deformity in the middle-aged and old people.
METHODThe lacrimal groove and palpebromalar groove deformity was corrected by the techniques of transcutaneous orbital fat releasing and pedicle orbital fat flap filling. From 1996 to 2011, 426 patients, aged from 35 to 72 (average, 48), were treated by the techniques. Among them, 54 patients had underwent the surgical treatment before this operation. 362 patients were followed up for 3-24 months.
RESULTSCompletely correction was achieved in 283 patients, obvious improvement in 79 patients. The result was not satisfied in 2 patients with severe deformity who had surgical treatment before.
CONCLUSIONThe lacrimal groove and palpebromalar groove deformity can be effectively corrected by transcutaneous orbital fat releasing and pedicle orbital fat flap in the middle-aged and old people.

OBJECTIVE To evaluate the use of antibiotics in general hospitals of Ningbo. METHODS Totally 4 391 case history records in April,2004 of 12 hospitals were investigated on the use of antibiotics. RESULTS Medicines incomes accounted for 55.16% in total revenue in a hospital,and antibiotics accounted for 32.66% among medicines incomes.Antibiotics using rate was 62.11% in internal medicine departments.The percentage of antibiotics using without evidence was 23.92%,the combined antibiotics using rate was 49.89%.The average duration for antibiotics using was 10.83 days.Antibiotics using rate in surgery departments before operation was 71.00%,during operation was 20.48%,the combined antibiotics using rate during operation was 14.50%,antibiotics using rate after operation was 96.55%.Antibiotics using for treatment accounted for 62.37% and for prevention was 24.17%. CONCLUSIONS Antibiotics using rate is high in hospitals in Ningbo.Income of medicine is also an important part of total revenue in a hospital.We should pay more attention to management on clinical use of antibiotics.

Objective To study the inducement of U251 glioblastoma cell apoptosis in vivo through up-regulating PUMA expresion and knocking down miR-221/222, and explore its mechanism.Methods Nude mouse xenograft models were established in 5-week-old BALB/c nude mice by subcutaneous vaccination of U251 glioblastomas; 1 week later, they were treated with intratumoral injection of lipofcctamine-mediated miRNA-221/222 antisense oligonucleotides (GroupA), nonsense sequences (Group B) and controls (Group C),respectively (n=8).The tumor growth was monitored until the end of observation period (28 d after the treatment) and pathological changes of the glioblastoma tissues were observed by HE staining at the end of observation.Fluorescence in situ hybridization (FISH) and real-time PCR were employed to measure the miR-221 and miR-222 expressions. Terminal deoxynucleotidyl transferase-mediated uridine 5'-triphosphate-biotin nick end labeling (TUNEL) assay was used to detect the apoptosis of glioblastomas.Immunohistochemistry and Westem blotting were used to detect the expressions of PUMA,bax,bcl-2 and p53 in removed tumor specimens. Results The volume in Group A was significantly smaller than that of those in group B and group C 6-28 dater treatment (P=0.006). The miR-221 and miR-222 mRNA expressions in Group A were significantly decreased as compared with those of those in group B and group C.HE staining indicated that decreased heteromorphism and reduced number of new vessels in Group A were noted as compared with those in group B and group C.The cell apoptotic index in Group A was significantly higher than that in group B and group C (P<0.05).Immunohistochemistry showed that the expression levels of PUMA and bax in Group A was significantly up-regulated as compared with those in group B and group C, while the expression of bcl-2 in Group A was significantly down-regulated as compared with that in group B and group C; and no significant changes were noted in the p53 expression. Conclusion By up-regulating PUMA expresion,knocking down miR-221/222 can induce U251 glioma apoptosis in vivo.
