Objective To study the diagnosis and treatment of adrenocorticotrophic hormone (ACTH) independent Cushing syndrome. Methods A retrospective review was done on 89 patients with ACTH independent Cushing syndrome, including 85 cases of adrenal tumors with hypercorticism, 2 cases of adrenocortical adenocarcinoma and 2 cases with ACTH independent macronodular adrenal hyperplasia. Results Favorable results were observed from the surgery for 85 cases of adrenal tumors combined with hypercorticism.Two cases with ACTH independent macronodular adrenal hyperplasia were cured by bilateral adrenolectomy. Adrenal cortical adenocarcinoma was unresectable for both the patients who survived 7 and 9 months respectively. Plasma ACTH,dexamethasone suppression test,B ultrasonography and CT scan were useful for the diagnosis and differentiated diagnosis of ACTH independent Cushing syndrome. Conclusions Prognosis of adrenal tumors with hypercorticism and ACTH independent macronodular adrenal hyperplasia is favorable after surgery,whereas the prognosis of adrenal cortical adenocarcinoma is poor.

Objective To investigate the effects of preoperative jaundice relieving on hemihepatectomy of hilar cholangiocarcinoma.Methods The clinical data of 18 patients who received preoperative percutaneous transhepatic cholangiography and drainage (PTCD) or endoscopic nasobiliary drainage (ENBD) before hemihepatectomy at the Tongji Hospital of Huazhong University of Science and Technology from January 2007 to January 2012 were retrospectively analyzed.The condition of the 18 patients (jaundice relieving group) was compared with that of 24 patients (non-jaundice relieving group) who did not receive PTCD or ENBD before hemihepatectomy.The differences in the pre-and postoperative blood loss,blood transfusion,operation time and postoperative incidence of complications between the 2 groups were analyzed.All data were analyzed using the t test or chi-square test.Results After PTCD or ENBD,the levels of total bilirubin (TBil),direct bilirubin (DBil),alanine aminotransferase (ALT) were (27 ± 5) μmol/L,(22 ± 6) μmol/L and (52 ± 42) U/L,which were significantly lower than (287 ± 120)μmol/L,(212 ± 86)μmol/L,and (267 ± 180)U/L before PTCD or ENBD in the jaundice relieving group (t =4.33,6.61,4.19,P ＜0.05).In the jaundice relieving group,left hemihepatectomy was performed on 14 patients,and right hemihepatectomy on 4 patients,and the radical resection rate was 16/18.In the nonjaundice relieving group,left hemihepatectomy was performed on 11 patients,and right hemihepatectomy on 13 patients,and the radical resection rate was 83.3％ (20/24).There was no significant difference in the radical resection rate between the 2 groups (x2 =1.09,P ＞ 0.05).The operation time,volume of intraoperative blood loss,volume of blood transfusion were (5.0 ± 0.8) hours,(562 ± 207) ml and (430 ± 317) ml in the jaundice relieving group,and (6.3 ± 1.5)hours,(815 ± 463)ml and (750 ± 146)ml in the non-jaundice relieving group,with significant differences between the 2 groups (t =4.77,7.80,4.65,P ＜ 0.05).The incidences of postoperative complications,bleeding and postoperative hepatic failure were 3/18,1/18 and 1/18 in the jaundice relieving group,and 75.0％ (18/24),33.3％ (8/24) and 33.3％ (8/24) in the non-jaundice relieving group,with significant differences between the 2 groups (x2=5.14,7.58,7.58,P ＜ 0.05).Conclusion Preoperative jaundice relieving could shorten the operation time and reduce the volume of intraoperative blood loss and the incidence of postoperative complications.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

Objective To evaluate chest CT features of microscopic polyangiitis(MPA).Methods Clinical data and chest CT images of 66 patients diagnosed as MAP had been collected.Depending on clinical manifestations.the 66 cases were divided into the active group and the stable group.The data of two groups were analyzed by x2 test.Results Forty-three of 66(65.2%)CT images were abnormal including 32 of them in active group and 11 in stable group. In these patients,CT images showed ground glass opacities(53.5%),lung consolidations(23.2%),scattered patchy opacities(44.2%),ground glass opacities and/or lung consolidations(76.7%),reticular opacities(65.1%),honeycomb(14.0%),pleural effusions(48.8%),emphysema(18.6%),and mediastinal adenopathies(58.1%).Lung consolidations,ground glass opacities,scattered patchy opacities,mediastinal adenopathies,and pleural effusion in the active group are more common than that in the stable group(X2=4.479,4.083,4.053,9.697,9.345 respectively,P<0.05).Conclusion Chest CT features of in patients with MPA have difference between active and stable periods.The chest CT scan is a useful tool to diagnose MAP in different periods and guide the treatment.

Objective To observe the effect of daidzein on extracellular matrix of uremic rats and to discuss its mechanism.Methods Uremic rat model were established by 5/6 nephrectomized. Model rats were devided into daidzein group, control group. Rats with sham-operation were regarded as the normal control. At time of baseline, 4th and 8th week after operation, urinary protein and biochemical detection were measured. The pathologic changes, fibronectin (FN) and typeⅣcollagen (ColⅣ) were investigated at 8th week. The Western-Blot and RT-PCR were used to measure protein expression and mRNA transcription of TGF-β1. Results At 8th week after operation, the urinary protein (12.35 ± 2.13 mg/24 hvs. 19.93 ± 3.19 mg/24 h), serum urea (10.11 ± 0.65 mmol/Lvs.12.09 ± 0.78 mmol/L) and creatinine (68.10 ± 2.51μmol/Lvs.77.63 ± 3.20μmol/L) in the daidzein group decreased significantly than those in the control group (P<0.01). The deposition of ColⅣ (16.33% ± 2.14%vs. 24.68% ± 3.97%) and FN (19.17 ± 2.68 vs. 29.35 ± 4.15) in the daidzein group decreased significantly than those in the control group (P<0.01). Compared with control group, the pathological lesion in the daidzein group was less serious. The mRNA transcription (0.37 ± 0.06vs. 0.64 ± 0.08) and protein expression of TGF-β1 (0.28 ± 0.09vs. 1.40 ± 0.13) in the daidzein group were attenuated significantly than those in the control group (P<0.05). ConclusionsDaidzein had a beneficial effect on uremic rats. It may be associated with a decrease of extracellular matrix accumulation.

Objective To investigate the effect of genistein on deposition of extracellular matrix(ECM) in uremic rats and its mechanism.Methods The uremic rat model was established by 5/6 nephrectomy.The model rats were divided into the genistein group(G) and control group (C).The sham-operation group served as the normal control(S).Urinary protein and biochemical indexes before operation,at postoperative 4,8 weeks were measured in various groups.The pathologic changes of renal tissue were observed.The glomerular sclerosis index(GSI) was evaluated by the semi-quantitative method.fibronectin(FN) and type Ⅳ collagen (ColⅣ) deposition situation were detected by using the immunohistochemical method.Western blot and RT-PCR were used to measure the protein expression and mRNA transcription of TGF-β1.Results Comparing postoperative 4 weeks with the group C,the urinary protein excretion amount was decreased[(11.63 ± 2.07) mg/d vs.(19.93 ± 3.19) mg/d,all P＜ 0.01],serum urea nitrogen and creatinine levels of the group G were decreased[(9.39±0.59)mmol/L vs.(12.09±0.78)mmol/L,(65.11±3.79)mmol/L vs.(77.63±3.20)μmol/L,all P＜0.01].Until postoperative 8 weeks,the urinary protein excretion amount was decreased and the decrease of serum urea nitrogen and creatinine levels was more obvious.The deposition of ColⅣ and FN in renal glomerulus was lower than that of the control group[(17.30±1.96)％ vs.(24.68±3.97)％;(18.26±2.31)％ vs.(29.35±4.15)％,all P＜ 0.01].Glomerular sclerosis was significantly alleviated.The TGF-β1mRNA and protein expression were attenuated (P＜0.05).Conclusion Genistein can reduce the deposition of ECM in uremic rats and has a protective effect on kidney.
