Objective To evaluate the safety and efficacy of adrenal autotransplantation for the treatment of persistent Cushing's disease after transsphenoidal pituitary tumor resection. Methods Four patients were treated by adrenal autotransplantation with attached blood vessels after bilateral adrenalectomy for persistent Cushing's disease from April 1991 to March 2008 in our institute. The four patients were 3 females and 1 male. Their ages ranged from 14 to 36 years, with an average of 30 years. Right adrenalectomy was performed 1 to 3 months before the left adrenalectomy. 30 % ?50 % of the left hyperplastic adrenal was placed in the left inguinal region with the anastomosis of the inferior epigastric artery and the central adrenal vein, and between the left saphenous vein and the incised adrenal envelope with the adrenal middle artery inside. The hormone replacement dosage decreased gradually after operation. They were followed up for 1.0, 1. 5, 8. 0 and 10. 0 years. The patient's symptoms, adrenal hormone (serum cortisol, urinary free cortisol and adrenocorticotroph) levels and the steroid replacement dosages were recorded and analyzed. Results The symptom of the Cushing's disease disappeared completely after operation and there was no Nelson's syndrome except one patient with slight darken skin. Through 4 ways of imaging examination, operation, clinical presentation and endocrine examination, the 4 transplanted adrenals functioned well with less steroid replacement dosage needed after operation. The 4 transplanted adrenal glands functioned steadily 1 year after the auto-transplantation, and no hyperplasia was detected in the transplanted adrenals with the stimulus of high dosage adrenocorticotroph. Conclusions The long-term effects of adrenal autotransplantation with attached blood vessels after bilateral adrenalectomy is effective and safe. Adrenal autotransplantation can be a feasible option for the treatment of persistent Cushing's disease.

Erythropoietin (EPO) is an active glycoprotein synthesized by kidney. The physiological function of regulat?ing the synthesis of erythrocytes by EPO makes it as a clinical drug for treatment of anemia resulted from chronic kidney fail?ure. However, its short biological half-life makes frequent administration, which limits its wide clinical utility since the tough burden and pain on patients. Therefore, the development of EPO derivatives with good efficacy, less adverse reaction and long duration has been a hot spot in the field during several decades. There are currently many different variants of EPO derivatives including erythropoiesis stimulating agents (ESAs) on the market. This article aims to summarize the recent re?search progress in the development of erythropoietin derivatives, specially focusing on EPO mimetic peptides (EMP).

Objective To study the classification and treatment of juxtaglomerular cell tumor of the kidney. Methods Five cases of juxtaglomerular cell tumors of the kidney were diagnosed and treated surgically in our hospital during the last 4 years. Seven large series of cases report of juxtaglomerular cell tumors have been published in the Pubmed. These series of cases report plus 1 case report of static juxtaglomerular cell tumor were incorporated into a review of 71 cases previously published in English literature. The clinical presentation, laboratory examination and imaging study were summarized. The clinical presentation including blood pressure, the laboratory examinations including kalium, plasma renin activity and aldosterone, and renal venous sampling for renin assay, and the imaging study including ultrasonography, CT, excretory urography, and selective renal angiography were studied retrospectively. Results The 71 cases juxtaglomerular cell tumors could be classified into 3 types, that is, typical type, atypical type and static type. The 57 typical cases had the typical characteristics of hypertension, hyperaldosteronism, and hypokalemia secondary to tumor renin secretion.The 12 atypical cases had hypertension with normal kalium, and the 2 static cases had normal blood pressure and kalium. Typical juxtaglomerular cell tumor of the kidney should be considered in hypertensive patients with secondary aldosteronism. Atypical juxtaglomerular cell tumor of the kidney should be considered in patients with hypertension and renal tumor. Static juxtaglomerular cell tumor of the kidney should be considered in patients with benign renal tumor. Conclusions The classification of typical, atypical and static juxtaglomerular cell tumors depends on blood pressure and serum kalium. As a surgically corrected disease, juxtaglomerular cell tumor of the kidney should be considered in patients with benign renal tumor, and nephron-sparing surgery is the first choice.

Severe acute respiratory syndrome is an infectious disease caused by a new type of coronavirus. It belongs to the seasonal febrile diseases in traditional Chinese medicine. The prevention and treatment of severe acute respiratory syndrome (SARS) can be under the guidance of the doctrines for treating febrile diseases of traditional Chinese medicine, treatment based on syndrome differentiation, such as syndrome differentiation of triple energizer, syndrome differentiation according to defensive phase, qi phase, nutrient phase and blood phase. During April and May of 2003, 8 cases of SARS were diagnosed in Shanghai, and 6 patients accepted complementary therapy of traditional Chinese medicine, without death case. The only one patient who didn't take glucocorticoid therapy was complementarily treated with traditional Chinese herbs through the whole treating procedure. Upon the successful treatment of the eight cases of SARS in Shanghai, it is demonstrated that the triple-energizer syndrome differentiation and defensive-qi-nutrient-blood syndrome differentiation in traditional Chinese medicine are of high value in treating SARS patients.

Objective To investigate the protective effect of mild hypothermia at different starting times on the physiological functions of the viscera of exertional heat stroke (EHS). Methods A prospective randomized controlled trial was conducted. EHS patients admitted to intensive care unit of the 159th Hospital of People's Liberation Army and the First Affiliated Hospital of Zhengzhou University from June 2015 to June 2017 were enrolled. The patients were divided into 2, 4, 6 hours start hypothermia treatment groups according to the random number table method, the mild hypothermia was initiated at 2, 4 and 6 hours after the disease onset respectively, and the methods were the same in each group. After treatment of 2, 12, 24 hours, the venous blood in the three groups was collected to detect serum cardiac troponin I (cTnI) with chemiluminescence method, MB isoenzyme of creatine kinase (CK-MB) with immunosuppressive method, creatinine (Cr) with creatine oxidase method, β2-microglobulin (β2-MG) with turbidimetry, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) with enzyme method. Multiple organ dysfunction syndrome (MODS) within 24 hours after treatment was recorded. Linear regression analysis of the correlation between mild hypothermia start-up time and MODS was done. Results Ninety-three cases of EHS were included,with 32, 31 and 30 patients in 2, 4, 6 hours start treatment groups respectively. There were no significant differences in gender, age, core temperature, onset time to admission, Glasgow coma scale (GCS), acute physiology and chronic health evaluation system Ⅱ(APACHE Ⅱ) score at admission among the three groups. There were no significant differences in the levels of serum cTnI, CK-MB, Cr, β2-MG, ALT and AST at 2 hours after treatment. But with the prolongation of the treatment time, all indicators gradually increased. And the earlier start of the mild hypothermia, the less significant of the above indexes. All indexes in 2 hours start treatment group were significantly lower than those of 2 hours and 6 hours start treatment groups at 24 hours after treatment [cTnI (ng/L): 49.53±9.25 vs. 56.52±10.05, 64.57±11.21; CK-MB (U/L):51.47±11.83 vs. 57.87±7.43, 64.40±7.93; Cr (μmol/L): 140.97±11.33 vs. 148.16±10.39,155.57±8.65; β2-MG (mg/L): 10.28±1.46 vs. 11.58±2.13, 12.93±1.98; ALT (U/L): 248.53±75.47 vs. 341.42±129.58, 425.77±101.23;AST (U/L): 197.25±42.59 vs. 292.81±58.49, 351.20±60.41, all P < 0.05]. There was significant difference in the incidence of MODS in 2, 4, 6 hours start treatment groups [43.75% (14/32), 64.52% (20/31), 80.08% (24/30), χ2= 8.761, P = 0.013]. Linear regression analysis showed that the earlier onset time of mild hypothermia, the lower incidence of MODS (R2= 0.915, P = 0.013). Conclusion The application of mild hypothermia in 2 hours can effectively protect the physiological function of EHS organs and reduce the incidence of MODS.
