Objective To discuss the efficacy and safety of retroperitoneal laparoscopic ureterolithotomy in treatment of ureteral calculi.Methods All 33 cases with upper or midst ureter calculi were treated by laparoscopic ureterolithotomy,ESWL or URSL ineffective for 26 cases.The diameters of calculi ranged from 0.7 to 2.1 cm.Results All the operations were successful.The operation time was 30～120 min with a mean of 55 min.The intraoperative bleeding volume Was 40 ml (20～80 ml) on average no complication Was observed duing the follow-up of 6～12 months.All the hydronephrosis Was alleviated.Conclusion Laparoscopic ureterolithotomy is suitable for ureteral calculi treated unsuccesfully by open surgery.It is effective,safety and miniinvasive.

Medical Imaging faculty has made the teaching reform which is design-oriented and integrative with intent to cultivate students' innovation consciousness and practice ability in the teaching system,teaching method and writing new textbooks.From the teaching practice,we have obtained satisfactory teaching results and can provide one kind of clear train of thought for the college curriculum adapting to the demand of this society.

Job burnout of clinical teachers at affiliated hospital of medical college has be-come a problem that cannot be ignored today.The current situation and the causes of job burnout are discussed to provide directions for carrying out some intervention measures in the future.

The clinical teaching of medical colleges and universities is an important stage of medical education,the clinical teacher is the clinical teaching concrete undertaker,and the teaching quality is closely related to clinical teacher's work,therefore,in order to improve the quality of teaching,we must strengthen the clinical teachers'education and the continuing education through a variety of ways.

Objective To investigate the life satisfaction and its related factors in primary caregivers of breast cancer patients. Methods The Life Satisfactory Index A (LSIA) and self-administrated questionnaire were used. The life satisfaction between breast cancer patients'primary caregivers and breast benign patients' primary caregivers were compared. The factors of the life satisfaction in primary caregivers of breast cancer patients were analyzed. Results The life satisfaction was poorer in the breast cancer patients' primary caregivers than in the breast benign patients' primary caregivers (P<0.01). The life satisfaction in the breast cancer patients' primary caregivers was correlated with the stage of breast cancer, course of disease, primary caregivers' age and family monthly income (P<0.05). Conclusion The life satisfaction in breast cancer patients' primary caregivers is worse and is related with stage of breast cancer, course of disease, primary caregivers' age and family monthly income.

Objective To examine the neural basis of item memory and source memory with fMRI approach.Methods Eight male and eight female healthy fight-handed native Chinese speakers were involved in this study.The item memory and source memory task were conducted with 504 highly frequent Chinese double-character words in the Block-designed experiment.Participants underwent such a double- round procedure as fMRI scanning following study.The fMRI data collected from a GE 1.5T MRI system were analyzed to generate corresponding activation maps for females and males respectively(P20)using statistical parametric mapping software(SPM).Results For females,item memory task activated the bilateral dorsolateral prefrontal cortex(BA6,the number of activated voxel clusters was 62 or 11 in the left and the right,respectively),source memory more activated the left dorsolateral prefrontal cortex(BA6/46,the number was 59).For males,item memory activated the right dorsolateral prefrontal cortex(BA6/46,the number was 64),source memory activated the bilateral dorsolateral prefrontal cortex(BA6,9 and 40 in the left and the right).Conclusion On the neural basis of item or source memory,there exists dissociation,which is that right dorsolateral prefrontal areas are more activated by item memory while left dorsolateral prefrontal areas by source memory.For the difference of gender,it is suggested that left dorsolateral prefrontal areas(BA6/46)are more activated in females while right dorsolateral prefrontal cortex(BA6/46)more in males.

AlM:To investigate the expression of VEGF, CD34, Ki-67 and p21 in pterygium as well as the correlation between their expression and clinical pathological characteristics;explore its pathogenesis.
METHODS: lmmunohistochemical S - P staining method was adopted in detecting the expression of VEGF, CD34, Ki-67 and p21 in 62 cases of pterygia and 20 cases of normal conjunctival tissues. Relationship between these markers and clinical pathological characteristics was analyzed.
RESULTS:(1) The positive expression of VEGF, CD34, Ki-67 and p21 in 62 cases of pterygia was 74. 2% (46/62), 77. 4% ( 48/62 ), 66. 1% ( 41/62 ) and 40. 3% ( 25/62 ) respectively. The differences were statistically significant compared with normal conjunctival tissues (P<0. 05). (2) The expression of VEGF and CD34 in 62 cases of pterygia was correlated with clinical types and stages (P<0. 05), and was not associated with sex, age and occupation ( P>0. 05 ); the expression of Ki-67 was correlated with clinical stages (P<0. 05), and was not associated with other clinical pathological characteristics ( P>0. 05 ); the expression of p21 was correlated with clinical stages and pterygium characters (P<0. 05), and was not associated with other clinical pathological characteristics ( P> 0. 05 ). ( 3 ) Spearman correlation showed that there was a positive correlation between VEGF and Ki - 67 ( r = 0. 279, P < 0. 05 ), a positive correlation between VEGF and CD34 (r=0. 299, P<0. 05), a negative correlation between VEGF and p21 (r=-0. 267, P<0. 05 ); it also showed that there was no correlation between any two of CD34, Ki-67 and p21 (P>0. 05).
CONCLUSlON: ( 1 ) Overexpression of VEGF, Ki-67, CD34 and low expression of p21 suggest that these markers are concerned with the development and progression of pterygium. ( 2 ) Expression of VEGF and CD34 increases along with the increase of clinical types and stages, expression of Ki-67 increases along with the increase of clinical stages, and expression of p21 decreases along with the improvement of clinical types or stages; they suggest that these markers may play important roles in the development and recurrence of pterygium. ( 3 ) There is positive correlation between VEGF and Ki-67, VEGF and CD34 as well as negative correlation between VEGF and p21. They suggest that there may be synergistic action between two factors during the development and progression of pterygium.

Objective To evaluate the effects of cranial electrotherapy stimulation therapy combined with psychological intervention for treating depression after cerebral infarction.Methods Eighty persons diagnosed with depression after cerebral infarction were divided randomly into a treatment group and a control group.Both groups were given routine rehabilitation training and psychological intervention, but the treatment group also received microcurrent transcranial electrical stimulation treatment.All the patients were evaluated with Hamilton's depression scale (HAMD) and the mini-mental state exam (MMSE) and given Barthel index (BI) scores before and after 4 weeks of treatment.Results There was no significant difference between the 2 groups in terms of any of the measures before treatment.After 4 weeks of treatment, both groups had improved significantly, but the improvements on all measures were significantly better in the treatment group.Conclusion Cranial electrotherapy combined with psychological intervention can significantly improve symptoms of depression and cognitive function in patients with post-stroke depression, and play an important role in improving their daily life.
