Objective To explore the clinical features of adrenocortical oncocytoma for better understanding. Methods A total of 586 patients with adrenal cortical adenoma were retrospectively analyzed in our hospital from January 1993 to November 2009, in which 18 were diagnosed as adrenal cortical oncocytoma pathologically, with 7 male and 11 female, aged ( 45.5 ± 15.9 ) years, and the disease course of( 13.3 ± 13.1 )months. Results 6 patients suffered from Cushing's syndrome, 2 primary hyperaldosteronism, 1 had clinical features of both Cushing's syndrome and primary hyperaldosteronism, and 9 were nonfunctional. 4 cases were misdiagnosed as pheochromocytoma preoperatively. All 18 patients were diagnosed by B-mode ultrasound and operation ( 13 by laparoscopy, 5 by laparotomy). 11 tumors were located in the left adrenal while 7 in the right, with the average tumor size of 5.6 cm in diameter. Histopathologically, 1 was oncocytic adrenocortical carcinoma, while 17 were adrenocortical oncocytoma, in which 5 were potentially malignant and 12 were benign. 11 patients were followed up for 20.5±20.1 months. 2 patients were dead, and 9 were alive with tumor recurrence in 1 case.ConclusionsAdrenocortical oncocytoma is a pathological diagnosis and the clinical manifestations are various. The tumors are usually large in size, and can easily be found by ultrasound, but may be wrongly diagnosed as pheochromocytoma.Being different from previous reports, the majority of these patients present with endocrine dysfunction. Most of these cases are benign, but malignant potential is obvious. Therefore,follow-up is very important.

Objective To summarize the clinical characteristics of adrenal tumors combined with renal carcinoma and to extend the clinical understanding of the situation.Methods To analyze the data of 1 100 patients with adrenal tumors hospitalized in Peking University First Hospital from Jan.1994 to Mar.2012 retrospectively,in the series there were 42 combined with renal carcinoma.Results There were 27 males,15 females,aged 29 to 83 years,mean 60.5 years old.In 42 renal carcinomas,there were 29 (69.0％) clear cell carcinomas,5 (11.9 ％) cystic renal carcinomas,2 (4.8％)clear cell with granulosa cell hybrid carcinomas,1 renal lymphoma,1 (2.4％) spindle cell tumor,1 acidophilic cell adenoma,and 1 undifferentiated type of renal cell carcinoma and pathologically not clear in 2 cases (4.8％).Clinical manifestations were not specific.In 42 adrenal tumors,20 situated in the left,and 17 right,and 5 were bilateral.35 cases were considered primary adrenal tumors,in which 3 were diagnosed primary hyperaldosteronism,32 were non-functional tumors.Other 7 were non-functional matastatic carcinomas.25 patients underwent resection of adrenal tumors,and pathology revealed 22 (88.0％) were primary,in which 12 (54.6％) were cortical adenomas,7 (31.9％) hyperplasia,1 (4.5 ％) pheochromocytoma,1 (4.5 ％) ganglioneuroma,1 (4.5 ％)adenoma with hyperplasia;2 (8.0％)metastatic tumors,and 1 (4.0％) non-Hodgkin' s lymphoma.The mean diameter of primary adrenal tumors was 1.9 cm,while that of metastatic carcinoma was 3.84 cm.25 underwent abdominal ultrasonography,40 underwent computed tomography (CT) scan,6 underwent magnetic resonance imaging (MRI) scan,positive rate was 72.0％,97.5％,and 100.0％ respectively.25 patients who underwent surgery were followed up,17 survived for 8 months-6 years,4 died,in which 1 metastatic carcinoma died of intraoperative bleeding,1 died of adrenal lymphoma,2 died because of other disease,4 were lost to follow-up.Conclusions The most common type of renal carcinoma combined with adrenal tumors was clear cell carcinoma,while majority of the adrenal tumors were primary with non-specific clinical manifestations and function.The adrenal tumors might be located in the same or the opposite side of renal carcinoma,also might be bilateral which were more common in metastatic carcinomas and always bigger than primary ones.CT/MRI scans were important in judging the nature of the tumors and pathology was the gold standard.The non-functioning primary adrenal tumors could be safely followed up,and the isolated metastatic carcinoma should be resected.Prognosis depends mainly on that of renal carcinoma.

Objective To explore the preliminary mechanism of mesenchymal stem cells (MSCs) in promoting prostate cancer proliferation in tumor inflammatory microenvironment.Methods From April 2013 to October 2013,MSCs pretreated with inflammatory cytokine IL-1α (MSCs (IL-1α)) and its culture supernatants mixed with RM-1 cells,which origined from C57BL/6 mice,were subcutaneously administered in the armpit area of C57BL/6 or BALB/c mice to establish homologous or heterologous transplant animal mode and to detect the tumor growth.Meanwhile the influence of MSCs on the proliferation of spleen cells was detected in vitro.Results In homologous transplant model,the relative tumor weight of prostate cancer cells prtreated with MSCs and MSCs (IL-1α) and their culture supernatant were (3.4 ± 0.2),(3.3 ±0.2),(4.9±0.5),and (5.2±0.6) g.The results were statistically significant (P＜0.05) compared with the control group (2.4±0.2) g.In heterologous model,the ratio of tumor formation of the pretreated groups were 50％,50％,80％ and 80％,respectively,compared with the control group of 0％.The results were statistically significant (P＜0.05).In proliferation experiments of spleen cells,the number of spleen cell pretreated with IL-1α were significantly lower than that in control group and unpretreated group (P ＜ 0.05).Conclusions MSCs pretreated with IL-1α could effectively promote the growth of prostate cancer cell in vivo.The reason may be due to inflammatory cytokines induce immune suppression of MSCs and then lead to immune escape of cancer cells.

Objective To study the estradiolNGF regulatory cascade in retinal endothelial cells. Methods Retinachoroids vascular endothelial cell line RF/6A from rhesus was cultured in M199 medium contain 20% FBS.mRNA of ER,NGF and its receptors,TrkA and P75 NTR were detected with RTPCR.The cells were incubated with NGF,VEGF,antibodies against NGF or VEGF,and K252a(100nmol/L),the specific inhibitor of TrkA,separately or in different combination.MTT based cell counting assay was used to study the viability of the cells.The apoptosis was evaluated by FACS,mass migration by wound healing assay,and tubogenesis by AngioMatrix assay. Results We amplified the specific fragments of cDNA of ER,NGF and NGF receptor TrkA using RTPCR.10?nmol/L1??mol/L estradiol augments the proliferation and increases the viability of RF/6A in a dosage dependent manner.In the wound healing based migration assay,we found the similar alteration.This effects of estradiol was partially blocked by NGF neutralized antibody and K252a.Apoptosis rates were at the similar level among the groups.For the tubogenesis of RF/6A,we found no augmentation by NGF,and no blocked augmentation by estradiol.Conclusion NGF,first identified as the survival factor of nerve system,now also seemed to be an activator of retinal endothelial cell,is under the regulation of estrogen.The proliferation and migration,but not the tubogenesis of retinal endothelial cells are regulated by this regulatory cascade.

Different varieties of Terminalia chebula Retz. were identified by DNA finger prints, andat the same time, some problems encountered during the application of RAPD for the identification ofTCM were studied. The polymorphic features of DNA finger prints of different species were compared.Results of the study showed that they were differently related in heredity which can provide a basis for thedifferentiation of one species from the other. Means for the solution of problems arised during RAPD ap-plication were suggested. It was concluded that RAPD is an effective method to identify T. chebula from itsconfusable varieties.

Objective To evaluate the ergotropic effect of bone cement on pedicle screw fixation in treatment of osteopo-rotic thoracolumbar fracture.Methods Fifty-three patients with osteoporotic thoracolumbar fracture, admitted from Jun. 2013 to Dec. 2014, were included for treatment by augmentation of pedicle screw fixation with bone cement. All patients underwent pre-operative examination of bone mineral density with T-score ≤-2.5 and augmentation of pedicle screw fixation with injection of 1.5 ml bone cement in adjacent to fractured vertebra. All patients were treated with anti-osteoporosis therapy pre- and post-operation, ob-served and recorded with basic conditions and complications. At pre-operation, one-week post-operation and last follow-up, pain vi-sual analogue scale (VAS) and neurological function score (ASIA) of all patients were recorded, and the compression rats of anterior and posterior edge of fractured vertebra, and compression rats of spinal canal and Cobb angel of all patients were measured.Results All the 53 patients were successfully undergone operation in about 90-140 min with blood loss of about 150-350 ml. No spinal cord or nerve injury, dural tear and obvious leakage of bone cement and screw loosening occurred during operation. All patients were followed up for 12 to 36 months and the neurological function obviously recovered contrasted with pre-operation. X-ray and CT examination at last follow-up showed good fractures healing, good position and non-loosening of internal fixation device and non-leakage of bone cement. At one week post-operation and last follow-up, VAS, compression rats of anterior edge and posterior edge of fractured vertebra, compression rats of spinal canal and Cobb angel were significantly lower than those at pre-operation (P<0.05), but no significant differences existed on these parameters between 1 week post-operation and last follow-up (P>0.05).Conclusions Augmentation of pedicle screw fixation with bone cement can effectively strengthen the initial stability of pedicle screw in osteo-porosis, restore the height of fractured vertebra and reduce the compression of spinal canal, which will help the correction of spinal kyphosis and neurological function recovery. This method can well maintain long-term stability of internal fixation in osteoporosis and height of fractured vertebra, and significantly reduce the risks of long-term screw loosening and vertebral collapse.

Objective To analyze the thickness of cornea and corneal epithelium in healthy subjects by optical coherence tomography angiography (OCTA).Methods Totally 100 healthy subjects aged between 20 and 30 years were analyzed by OCTA technique.Using AngioVue OCTA system of retinal imaging mode,and using SSADA algorithm for imaging,the cornea and the corneal epithelium in the central corneal diameter range of 9 mm were measured.The differences of corneal and corneal epithelial thickness in different gender regions were compared.Results In the male and female group,the corneal central total thickness were (559.92 ±33.26) μm and(540.06 ±31.63)μm,and the corneal epithelial thickness were(57.78 ±4.88) μm and(56.88 ±4.57) μm,The total central corneal thickness and central corneal epithelial thickness of the male were greater than those of the female,the difference was statistically significant (t =3.06,2.10;all P ＜ 0.05).The cornea of male was the thickest at S5,S7 and SN9,there were significant differences at S5 and S7 compared with female (t =2.93,2.83;all P ＜ 0.05);The female cornea was the thickest at S5,SN7 and SN9,and the difference was significant at S5 compared with male.The cornea of male subjects was the thinnest at IT,which was statistically significant only at IT5 compared with female subjects in the same area (t =2.02,P ＜ 0.05);The cornea of female subjects was the thinnest at T5,IT7 and T9,which was statistically significant only at T5 and T9 compared with male subjects in the same region (t =2.63,2.20;all P ＜ 0.05);There was significant difference in corneal thickness between male and female at ST (t =3.1 1,2.79,2.33;all P ＜ 0.05).The corneal epithelium was the thickest at IT5,I7,and I9,and the lowest at S5,S7 and S9,and there was no significant difference compared with female in the same region (all P ＞ 0.05).The corneal epithelium of female at the IT5,T7,N9 were the thickest,SN5,S7,S9 were the thinnest;Except for M2 and SN5,there was no significant differences in corneal epithelium between male and female groups (all P ＞ 0.05).Corneal central epithelium accounted for the largest percentage of total corneal thickness,and gradually decreased from inside to outside.Conclusion OCTA can be used to measure the thickness of corneal and corneal epithelial regions.
