Objective To explore the efficacy of low-dose aripiprazole combining with citalopram on the depression. Methods A total 57 patients with depression were randomly assigned to the study group and the control group. Either group was treated with a fixed dose 20 mg citalopram per day, and the study group was simultaneously titrated to low dose (5～10mg/d) of aripiprazole at initiating dose 2.5 mg per day within two weeks. They were evaluated with Hamilton Depression Scale (HAMD).Clinical Global Impression (CGI-SI) and Treatment Emergent Symptom Scale(TESS) before treatment and at the end of 1st, 2nd, 4th and 6th week after treatment. The study lasted for 6 weeks. Results HAMD total score of either group were 11.54 ± 5.58 and 16.59 ± 6.67 respectively, which had statistically significant difference between two groups(t = 2.961, P<0.05) at the end of the study. CGI-SI score of either group was 2.12 ± 1.47 vs 3.17 ± 1.63 at treatment termination, which also had statistically significant difference (t = 2.439, P<0.05). There were mild side effects rate and no statistically significant difference between two groups (χ~2 =0.625, P>0.05). TESS scores were not statistically significant difference between two groups at each point of measure. Conclusion The results suggest low dose of aripiprazole augmentation of citalopram may be effective and safe in the treatment of depression.

Under active exploration and practice of several generations of organ transpant workers,organ transplantation in China has developed rapidly since 2000 and achieved remarkble results.Techniques of transplantation become mature,and liver transplantation and renal transplantation have reached international advanced level,which benefit massive patients.With high attention and promotion of national government and health administrative departments,structural changes have occurred to source of national organ transplantation to form a China Model.The donation after citizen's death has become the new normal in the organ transplantation in China.Human organ donation work promots the rapid development of transplantation in China,but it also faces challenges of the donor organ shortage and quality improvement.Under the new situation,health,family planning and medical reform work of the national13th Five Year Plan puts forward new requirements on human organ donation and transplantation.Combined with practical work,this article gives a few opinions on how to scientifically further improve the quality and quantity of organ donation and transplantation and directions of future works.

Objective To discuss the diagnosis and outcome of adult endodermal sinus tumor oftestis.Methods The clinic data of 6 cases of adult endodermal sinus tumor of testis were reviewed.The patients' average age was 28 years.Five patients complained of an asymptomatic scrotal mass and1 patient complained of the pain of cryptorchidism.All patients received radical orchiectomy as initialtreatment.Pathology results suggested 2 patients with stage Ⅰ disease,3 patients with stage Ⅱ diseaseand 1 patient with stage Ⅲ disease.All were treated with chemotherapy or radiotherapy following rad ical orchiectomy.Retroperitoneal lymph node dissection(RPLND)was performed in Ⅰ case with stageⅡ disease.Results Six cases of adult endodermal sinus tumor of testis were confirmed by patholo gy.Five patients were followed up for 1.5 year to 8 years,no local recurrence and distant metastasiswere found.Conclusions Adult endodermal sinus tumor is a rare neoplasm of the germinal cell line.Pathological examination is the key to diagnosis.Postoperative combination chemotherapy and radio therapy are the most common means of this disease.

Objective To investigate the effect of diet on the expression of protein tyrosine phosphatase (PTP) 1B in liver of insulin resistant rats induced by high fat diet. Methods 30 male Wistar rats were randomly divided into the control group (n=10) which was given basic diet, and the model group (n=20) which was given high fat diet. After 4 weeks, the model group was randomly divided into 2 subgroups:insulin resistant group which continued to receive high fat diet, and diet-treated group which accepted diet intervention for 6 weeks. The protein expression level of PTP1B in the liver of rats were determined with western blotting at the end of 10th week. Results The protein content of PTP1B in the liver of insulin resistant rats significantly increased by 98.3% compared with the control group (t=9.335,P

[Objective]To study the relationship between the existence and types of mediopatellar plica versus the chondral injury of the medial femoral condyle.[Method]Data were collected retrospectively from the photographic recording of arthroscopies performed from January 2004 to July 2008.Seventy-six knees were found with mediopatellar plica as the study group.Modified Sakakibara classification and the chondral injury(using the Outerbridge classification) of medial femoral condyle were recorded.Eighty knees without mediopatellar plica were randomly collected as controls.The correlation of mediopatellar plica and the cartilage injury on the surface of the medial femoral condyle was investigated.[Result]Patients with mediopatellar plica had a significantly higher incidence rate(89.5%) of medial femoral condyle cartilage lesion,in comparison with patients without mediopatellar plica(61.3%)(P=0.001).In the study group,a 64.3% proportion of the group with Sakakibara A mediopatellar plica was found to have cartilage lesion in the medial femoral condyle.The proportion of the group with Sakakibara BCD mediopatellar plica was found to be 95.2%,significantly higher than that in first group(P=0.004).The severity of cartilage injury in the medial femoral condyle was positively correlated with patient age(r=0.271,P=0.019) and the severity of the pathologic change of the mediopatellar plica(r=0.611,P=0.000).[Conclusion]According to this observation,the cartilage injury in the medial femoral condyle is more commonly found in patients with mediopatellar plica knees.A shelf-like appearance of the medial plica can increase the incidence of the cartilage injury.The severity of cartilage injury was positively correlated with patient age and the severity of the pathologic change of the mediopatellar plica.

Objective To discuss the diagnosis and outcome of multilocular cystic renal cell car-cinoma. Methods The clinic data of 1 case of multilocular cystic renal cell carcinoma were reviewed with its clinical manifestation, imaging, pathology and therapy in our hospital. The male patient aged 49 was incidentally found to have a right renal tumor. The CT scan showed a multiloeular cystic tumor in the low pole of the right kidney with a clear outline. The thin septa were found in the tumor, which were enhanced in the enhancement CT scan. The enhancement MRI showed the cystic wall was en-hanced. Results The patient received a partial nephrectomy as his treatment. The pathological char-acteristics were as following: the multilocular cystic tumor was about 3 cm×2 cm×2 cm with clear serosity in it. The cystic wall was smooth with the width of 0.1-0.2 cm. Most of the cystic cavities were covered by monostratified or stratified cubic clear cells, and some were covered by squamous epi-thelium or no epithelium at all. The septum was composed of collagen fiber, and clear cells were found in it. The clear cells form small collections but do not form expansile nodules. The final pathological diagnosis was multilocular cystic renal cell carcinoma. The follow-up was 20 months, without local re-currence or distant metastasis was found. Conclusions Multilocular cystic renal cell carcinoma (MCRCC) is a rare variant of renal cell carcinoma with a good prognosis. MCRCC is an uncommon tumor of the kidney composed of multiple cysts with clear cells in the septa indistinguishable from grade I renal cell carcinoma. Most patients are asymptomatie and the tumors are discovered inciden-tally. The preoperative diagnosis of MCRCC immediately depends on imaging studies. Pathology is the key to diagnosis.

Aim To explore the neuroprotective effects and possib le mechanism of bellidifolin on focal cerebral ischemia in rats.Methods Focal ce rebral ischemia was induced by permanent occlusion of the proximal portion of ri ght middle cerebral artery occlusion (MCAO). A neurological examination was perf ormed on each rat 4 hours,24 hours after ischemia by the method of Berderson .T he infarcted size was measured by 2,3,5-triphenrytetrazolium chloride(TTC) st aining technique at 24 hours post-ischemia.Effect of bellidifolin on intercellu lar adhesion molecule-1 (ICAM-1) and B lymphocyte myeloma (Bcl-2) immunoreact ive positive cells in peri-infarct region following ischemia and the histological neuronal changes were observed by means of immunohistochemical staining and H E staining.Result Bellidifolin significantly reduced infarc- ted size and improved the neurological deficit in rats .Bellidifolin produced effects of reduction in expression of ICAM-1 and upregulation of antia poptotic protein Bcl-2 on focal cerebral ischemia.Conclusion B ellidifolin has neuroprotective effects on focal cerebral ischemia in rats by or al administration.Mechanism of neuroprotective effects is related to downregulat ion of ICAM-1 and upregulation of antiapoptotic protein Bcl-2 on focal cerebr al ischemia.
