OBJECTIVE: To study the clinical and pathological features of pilomatricoma. METHOD: The authors retrospectively investigated the clinical and pathological materials of 399 patients with pilomatricoma. RESULT: Single lesion occurred in most patients (99%) and 56.39% of them were younger than 30 years. The male-female ratio was 1:1.33. The lesions which sizes average 1.22 cm were commonly emerged in the head, neck, and upper extremity. CONCLUSION Pilomatricoma is a slowly developed benign cutaneous tumour, but it can aggravate sometimes. It's manifestation is diversed and easily misdiagnosed. Early complete excision is recommended for hard or tenacious nodules on head, neck and upper extremity.

Objective To investigate the effects of ceftriaxone on depressive-like behavior and changes of hippocampal glutamate transporter-1 (GLT-1) in C57 mice depression model,and to further explore the molecular mechanism of ceftriaxone on antidepressant action.Methods Thirty male C57 mice were randomly divided into control group(group A,n=10),CUS group(group B,n=10) and CUS+ceftriaxone group(group C,n=10).The mice of the CUS group and the CUS+ceftriaxone group were subjected to chronic unpredictable stress (CUS) for 2 sessions per day for 21 days.Then,the mice of the CUS+ceftriaxone group were given ceftriaxone for 21 days.Behavioral changes were assessed by the sucrose preference test and open field test.The GLT-1 protein levels in the hippocampus were detected by Western blot analysis at the end of the ceftriaxone treatment.Results (1) Compared with the control group,the percentage of sucrose preference,the total traveled distance,the moved velocity,and the frequencies of rearing of the CUS group were significantly decreased(P＜0.05) at the 21 days.However,the percentage of sucrose preference ((78.74 ± 3.54) ％),the total traveled distance ((6818.35 ± 505.14) cm),the moved velocity((12.36±0.89) cm/s),and the frequencies of rearing(58.20±4.05) of the CUS+ceftriaxone group at the end of the ceftriaxone treatment were improved significantly compared with the CUS group ((59.46 ± 2.75) ％,(2931.71±271.89) cm,(5.84±0.42) cm/s,(26.20±2.62),P＜0.05).(2) Western blot analysis indicated significant reductions of the GLT-1 protein levels in the hippocampus of CUS group (versus the control mice:P ＜0.05),and chronic ceftriaxone treatment reversed the CUS-induced decrease in the GLT-1 levels(P＜0.05).Conclusion Ceftriaxone might significantly improve depressive-like behavior in C57 mice depression model.Chronic unpredictable stress (CUS) could down-regulate the GLT-1 protein levels in the hippocampus,which are reversed by ceftriaxone.These results further support the notion enhanced expression of the GLT-1 protcin can be molecular mechanism of ceftriaxone on antidepressant action.

The glutamate transporter EAAT 2 ( rodent nomencla-ture GLT-1:glutamate transporter 1), which is a predominantly astroglial glutamate transporter in the hippocampus and the pre-frontal cortex , is responsible for the majority of extracellular glu-tamate uptake .The glutamate transporter EAAT 2 can decrease the high levels of glutamate in the synaptic cleft , avoiding gluta-matergic excitotoxicity to damage the glial cells and neurons . Currently, the transporter EAAT2 has become a research hotspot of depression .This article aims to summarize roles of glutamate transporter EAAT2 in the occurrence and treatment of depres-sion.

Objective To investigate the feasibility and effectiveness of C57 mice depression model established by chronic unpredictable mild stress (CUMS) and separation.Methods 30 male C57 mice were randomly divided into three groups:CUMS + separation group (group CS),CUMS + separation + fluoxetine group (group CSF),and control group (group C).The mice of group CS and group CSF were fed with chronic unpredictable mild stress (CUMS) and separation for 3 weeks.Then,the mice of group CSF were given fluoxetine.To record the food intake/body weight,liquid consumption and field test of the mice at relevant time point.Results Compared with control group,the food intake/body weight,total route in the field test,and the sucrose solution consumption in liquid consumption test of group CS and group CSF decreased significantly (P＜0.05) at the 21th days.But after giving fluoxetine for 14 days,group CSF had no significant differences with group C except sucrose solution consumption.Although the difference of sucrose solution preferences was significant compared with control group(P＜0.05),it was improved significantly compared with CS group (P＜ 0.05).Conclusion The C57 mice depression model established by CUMS and separation are feasible and effective,and it is the ideal animal model of depression.

Aim To investigate the effects of fluoxe-tine on the changes of of protein levels of GLT-1 in pre-frontal cortex in rat depression model, and to further explore the molecular mechanism of antidepressant ac-tion of fluoxetine. Methods Sixty male SD rats were randomly assigned into three groups: control group, chronic unpredictable stress ( CUS) group, and CUS+fluoxetine group. The rats of CUS group and CUS+flu-oxetine group were subjected to CUS for 2 sessions per day for 35 days. Then, the rats of the CUS+fluoxetine group were given fluoxetine for 28 days. Behavioral changes were assessed by the sucrose preference and open field tests. The GLT-1 protein levels in the pre-frontal cortex were detected by immunohistochemistry and Western blot analysis at the end of the fluoxetine treatment. Results ( 1 ) Compared with the control group,sucrose preference, total traveling distance, ve-locity and frequencies of rearing were reduced in the CUS group ( P < 0. 01 ) . These behavioral changes could be reversed after 28 day fluoxetine treatment. (2 ) Immunohistochemistry assay indicated weak im-munoreactivity for GLT-1 in the prefrontal cortex of CUS group ( versus the control rats: P <0. 01 ); the immunoreactivity for GLT-1 of the fluoxetine-treated rats was significantly up-regulated compared with the CUS group rats ( P<0. 01 ) . ( 3 ) Western blot analy-sis indicated significant reductions of GLT-1 in the pre-frontal cortex of CUS group ( versus the control rats:P<0. 01 ) , and chronic fluoxetine treatment reversed the CUS-induced decrease in GLT-1 levels ( P <0. 01 ) . Conclusions Chronic unpredictable stress ( CUS ) could down-regulate the GLT-1 protein levels in the prefrontal cortex, which is reversed by fluoxe-tine. These results further support the notion that en-hanced expression of the GLT-1 protein could be mo-lecular mechanism of fluoxetine antidepressant effect.

Objective To analyze the clinical,pathological and CT features of mediastinal carcinoid so as to improve the diagnostic accuracy.Methods The clinical,pathological and imaging data of 4 patients with mediastinal carcinoid were analyzed retrospectively.Results All 4 patients were elderly male,in which 3 cases had elevated serum neuron specific enolase(NSE)before operation and other one was not examined.All tumors were atypical carcinoid with Ki-67 expression of 5％-25％and positive expression of Syn,CD56,CK and CgA.The CT showed the lateral mass on the left(n=3)or both(n=1)sides of the anterior mediastinum,3 of which grew along the vascular space and could not be clearly demarcated from the pericardium and cardiovascular system.The lesions were large with irregular shape in 3 cases and round shape in 1 case,with heterogeneous density in 3 cases and homogeneous density in 1 case,with intratumoral calcification in 2 cases.Contrast enhanced CT showed the lesions with mild or moderate progressive enhancement,3 of which had supplying vessels from internal thoracic artery.The enlarged mediastinal lymph nodes were found in 3 cases and bone metastasis was in 1 case.Conclusion Mediastinal carcinoid is more common in elderly male,usually with elevated serum NSE.CT shows lateral mass in the anterior mediastinum with heterogeneous density,intratumoral calcification,mild or moderate progressive enhancement,and supplying vessels from internal thoracic artery.The larger lesion is indistinguishable from the adjacent lung tissue and cardiovascular system,usually with intrathoracic and extrathoracic lymph node metastasis.
