Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

Objective To investigate the treatment of elderly dialysis patients with refractory hypertension.Methods Sixty-six patients were randomly divided into two groups of A group and B group,with 33 cases in each group.Patients in A group were treated by routine hemodialysis 3 times per week and hemoperfusion 1 time every 2 weeks.Patients in B group were treated by routine hemodialysis 2 times per week and hemodiafiltration 1 time per week plus hemoperfusion 1 time every 2 weeks.The levels of blood pressure,plasma endothelin (ET),angiotensin-Ⅱ (AT Ⅱ),renin (RA),parathyroid hormone (PTH) in two groups before and after treatment were compared.Results Before and after treatment,the levels of blood pressure,ET,AT Ⅱ,RA and PTH in A group were (183.42 ± 16.20)/(109.15 ± 7.69) and (151.45 ± 3.31)/(88.71 ±4.95) mmHg(1 mmHg =0.133 kPa),(173.45 ±41.25) and (160.38 ±25.31) ng/L,(69.21 ± 18.47)and(57.25 ± 23.34) ng/L,(1.21 ± 0.15) and (0.87 ± 0.14) μ g/L,(530.27 ± 43.28) and (272.43 ± 34.19) ng/Lrespectively.Before and after treatment,the levels of blood pressure,ET,AT Ⅱ,RA and PTH in B group were (185.34 ± 12.26)/ (112.38 ± 6.24) and (141.59 ± 4.15)/ (80.39 ± 2.73) mmHg,(178.21 ± 34.35) and (149.12 ±21.34) ng/L,(68.38 ±23.57) and (47.17 ± 15.61) ng/L,(1.19 ±0.29) and (0.69 ±0.41) μg/L,(528.62 ± 42.53) and (253.15 ± 31.62) ng/L respectively.The levels of blood pressure,ET,AT Ⅱ,RA and PTH in two groups after treatment were significantly decreased compared with those before treatment (P ＜0.05),and there were significant differences between two groups (P ＜ 0.05).Conclusion Combined with hemoperfusion in the treatment of elderly hemodialysis patients with refractory hypertension,the effect of combined hemodiafiltration is significant,and it is worthy of promotion.

Objective To evaluate the therapeutic effects of ultrasound biomicroscopy (UBM) assisted intraocular lens suspension surgery with one loop suturing for residual lens capsule aphakia.Methods Fifty aphakia patients (50 eyes) with residual lens capsular equal or greater than 180 degrees were chosen.The patients were randomly divided into 2 groups and underwent intraocular lens suspension surgery with one loop suturing:Trial group (25 cases,25 eyes) selected suture site according to the preoperative UBM results,and control group (25 cases,25 eyes) selected the suture site according to the clinical experience.The uncorrected visual acuity (UCVA),astigmatism at preoperative and postoperative 1 week,1 month and 3 months were observed,the eccentric and tilt value of the lens were calculated by UBM measurement at 3 month after operation,and the postoperative complications of the two groups were observed.Results UCVA at each time point after operation were higher than that before operation,and gradually increased with time.There was no significant difference between the two groups at 1 week before and after the operation of UCVA (P ＞ 0.05).At 1 month and 3 months after operation,UCVA in trial group were significantly higher than those of control group (all P ＜ 0.05).The astigmatism value at 1 week after operation in two groups was higher than that before operation and gradually decreased with time.The astigmatism value in trial group at 1 month and 3 months after operation had no significant difference with that of preoperative (P ＞ 0.05),while the astigmatism value in control group increased (all P ＜ 0.05).The astigmatism values had no significant difference between the two groups before and 1 week after operation (all P ＞0.05),which were significantly lower in trial group at 1 month and 3 months after operation (all P ＜ 0.05).Three months after surgery,the proportion of lens accurately implanted in the ciliary sulcus was significantly higher than control group (P ＜ 0.01),the eccentric and tilt values of the lens in trial group were significantly less than control group (P ＜ 0.01).No serious complication was observed in all patients.Conclusion UBM assisted intraocular lens suspension surgery with one loop suturing can significantly improve the postoperative visual quality,safety and lens stability,which can be used as a routine preoperative examination of intraocular lens suspension surgery.In addition,UBM provides an alternative method for the calculation of the eccentricity and tile value of the intraocular lens after the implantation of the intraocular lens.

Objective To evaluate the value and the expression of Axl receptor tyrosine kinase (AxlTK) in renal pathology of lupus nephritis (LN) patients. Methods The expression of AxlTK were detected in 29 LN and 10 primary nephritic syndrome (NS) patients using immunohistochemistry in renal tissue. The correlations between the levels of AxlTK on glomeruli and clinical manifestations, laboratory parameters, disease activity, and renal pathology in LN patients were investigated. T test and single factor analysis of variance were used tp compare between groups, and Pearson or Spearman test was used for correlation analysis. Results AxlTK was extensively expressed on surface of mesangial cells, endothelial cells in glomeruli. There was more expression of AxlTK on mesangial cells in LN patients [(7.0 ±2.2)×10-2] than that in primary NS patients [(3.1 ±1.2) ×10-2] (t=5.382, P<0.01). The expression of AxlTK in the glomeruli of LN patients with oral ulcers is higher than that in patients without of ulcers (t=2.259, P=0.032), and it was positively correlated with the anti-nucleosome antibody (AnuA) level in patients (r=0.488, P=0.017). The expression of AxlTK on glomeruli were higher in class Ⅳ and classⅢ of LN patients than that of class Ⅴ, but there was no statistically significant difference between them (P>0.05). Conclusion The expression of Axl TK in glomerular is significantly increased in glomeruli in LN patients. The expression level of AxlTK on glomeruli is correlated with the occurrence of oral ulcers and AnuA. The level of AxlTK expression is related to pathological categories of kidney in LN patients. The results of this study suggest that AxlTK might participate in the pathogenesis of LN.

Objective To investigate long-term data of dry eye after LASIK in young myopia patients.Methods Young myopia patients were divided into treated group (group A) and control (group B),who were interviewed before surgery and on 1 year,3 years and 5 years after surgery.Their diopters,uncorrected visual acuity (UCVA),tear breakup time test,Schirmer I test and corneal fluorescent staining were taken,then dry eye was diagnosed and OSDI questionnaire were scored.Results The postoperative incidence of dry eye in group A was higher than that before surgery (35.6％) and decreased with time (51.7％,44.9％ and 40.7％,respectively),and there was no significant difference in group B at each time point (P ＞ 0.05).The preoperative incidence of dry eye was equal between two groups (P ＞ 0.05),which were much higher in group A after surgery (all P ＜ 0.05).In group A,the postoperative constituent ratio of mild dry eye was the majority and decreased with time (65.6％,52.8％,41.7％,respectively),while moderate and severe dry eye was increased,especially the latter (6.6％,11.3％ and 16.7％,respectively;P ＜ 0.05).At 5 years after surgery,the UCVA and visual function score in dry eye patients were lower than those of non-dry eye patients (all P ＜ 0.05),while the residual refraction and ocular symptom score were higher than those of dry eye patients (all P ＜ 0.05).Conclusion Dry eye disease may last for a long time and may getting worse after LASIK.Therefore,we should pay more attention to the development of dry eye long after LASIK in young myopic patients.

OBJECTIVE: To study the protective effects of Naomaitong, a compound traditional Chinese herbal medicine, used together with thrombolysis therapy, on injuries of the lung and stomach in rats with cerebral ischemia. METHODS: Rats were randomly divided into sham-operated group, untreated group, urokinase group (thrombolysis group), Naomaitong group, thrombolysis plus Naomaitong group. Cerebral ischemia was induced in rats by autonomous blood blot and inserted nylon thread. Rats were administrated with thrombolysis therapy through artery 3, 6 and 9 h after cerebral ischemia respectively. Twenty-four hours after the administration, mortality of the rats, and the brain and stomach hemorrhage ratios, as well as the pathological changes of the brain, lung and stomach were observed, and then cerebral infarct size (CIS) and lung water ratio (LWR) were measured. RESULTS: Compared with the sham-operated group, the rat mortality, and the brain and stomach hemorrhage ratios increased, the CIS enlarged, pathological changes of the brain, lung and stomach appeared obvious, and the LWR increased. Naomaitong plus thrombolysis treatment improved the changes above significantly. In the untreated rats with cerebral ischemia, injuries of the brain, lung and stomach were aggravated, the CIS enlarged and the LWR increased in the 9 h group as compared with those in the 3 h group. In the thrombolysis plus Naomaitong group, the pathological changes were improved, the CIS diminished and the LWR reduced. CONCLUSIONS: Injuries of the lung and stomach can be caused by cerebral ischemia, and the impairment was exacerbated following the prolongation of the ischemia. Thrombolysis therapy can cause brain and stomach hemorrhage. Thrombolysis therapy used early can perform protection against the injuries. Naomaitong, used together with thrombolysis, can reduce the mortality, the brain and stomach hemorrhage ratios, and perform protective effects on the injuries of cerebral ischemia.
