Objective To investigate the therapeutic outcomes of unilateral adrenalectomy for Cushing syndrome in patients with adrenocorticotropic hormone (ACTH) independent bilateral macronodular adrenal hyperplasia.Methods 22 patients diagnosed with Cushing syndrome caused by ACTH independent bilateral macronodular adrenal hyperplasia from January 2005 to December 2015 were retrospectively concluded.There are 17 male patients and 5 female patients with the median age of 46.5 years.All patients were presented with Cushing syndrome such as moon face, buffalo hump and other typical symptoms of Cushing syndrome.The laboratory tests showed disappearance of cortisol rhythm, elevated 24-hour urinary free cortisol, suppressed or normal ACTH and unsuppressed low dose dexamethasone suppressing test.CT scan showed bilateral macronodular adrenal hyperplasia in all patients.Results All the patients received unilateral adrenalectomy.Pathological results showed adrenal cortex nodular hyperplasia.16 patients had reexamination in the endocrine department.The median follow-up time was 26 (17-118)months for these 16 patients.In the follow-up between 3 to 9 months after surgery, laboratory test showed serum and urinary cortisol level returned to normal range and Cushing syndrome also disappeared in these 16 patients.CT scan showed no recurrence.And no adrenal insufficiency occurred.One patient had recurrence one year after surgery and two patients turned better after surgery but had recurrence at 3 years and 10 years after surgery.Two patients received contralateral adrenalectomy and cortisol hormone replacement therapy after surgery.Another patient with recurrence refused second surgery.No recurrence was observed in other patients.Four patients were followed up by telephone, and all recovered well after surgery.18 patients had hypertension before surgery and their blood pressure significantly decreased after surgery.Among them 13 cases blood pressure returned to normal range.5 patients had elevated blood glucose before surgery, and 3 patients' blood glucose returned to normal range.Conclusions Unilateral adrenalectomy for Cushing syndrome in patients with ACTH independent bilateral macronodular adrenal hyperplasia is safe and effective.

BACKGROUND/AIMS: The integration of multiple profiling data and the construction of a transcriptional regulatory network may provide additional insights into the molecular mechanisms of hepatocellular carcinoma (HCC). The present study was conducted to investigate the deregulation of genes and the transcriptional regulatory network in HCC. METHODS: An integrated analysis of HCC gene expression datasets was performed in Gene Expression Omnibus. Functional annotation of the differentially expression genes (DEGs) was conducted. Furthermore, transcription factors (TFs) were identified, and a global transcriptional regulatory network was constructed. RESULTS: An integrated analysis of eight eligible gene expression profiles of HCC led to 1,835 DEGs. Consistent with the fact that the cell cycle is closely related to various tumors, the functional annotation revealed that genes involved in the cell cycle were significantly enriched. A transcriptional regulatory network was constructed using the 62 TFs, which consisted of 872 TF-target interactions between 56 TFs and 672 DEGs in the context of HCC. The top 10 TFs covering the most downstream DEGs were ZNF354C, NFATC2, ARID3A, BRCA1, ZNF263, FOXD1, GATA3, FOXO3, FOXL1, and NR4A2. This network will appeal to future investigators focusing on the development of HCC. CONCLUSIONS: The transcriptional regulatory network can provide additional information that is valuable in understanding the underlying molecular mechanism in hepatic tumorigenesis.

Objective To better understand the clinical management of tumor-induced osteomalacia (TIO) by analyzing the clinical features, diagnosis, treatment, postoperative biochemical changes, and clinical status in 12 cases of TIO. Methods Twelve cases of TIO hospitalized from 2004 to April 2010 were reviewed retrospectively. All cases were diagnosed based on their clinical manifestation, hypophosphatemia, and image study including technetium-99m octreotide scintigraphy (99mTc-Oct). Resuits There were 7 males and 5 females with mean age of (41.8±9.6) years (20 to 56 years). The course of disease was from 2 to 14 years ( median course 4.0 years). They all presented with bone pain, gait disturbance, muscle pain, and muscle weakness. Serum phosphate( Pi)levels were low in 12 cases with a range from 0.30 to 0.56 mmol/L. 99mTc-Oct was performed in 9 cases and it showed that the lesions were located in head of femur, fibula, retrocalcaneal area, foot, humerus,metacarpal, posterior chest wall or near nasal bone (apex partis petrosae ossis temporalis). Subcutaneous soft tissue mass was found in another 3 cases at loin, thigh, and foot by physical examination. The tumors were confirmed by CT, MRI or ultrasonography. Twelve patients underwent operation to remove the tumors and histopathology showed hemangioendothelioma or fibrous angioma (6 cases), giant cell tumor or fibroma of tendon sheath(4 cases), liposarcoma(1case), and phosphaturic mesenchymal tumor(1case). Serum Pi levels returned to normal in 10 patients after resection of tumor. During 2 to 64 months follow up, symptoms of bone pain and muscle weakness were improved obviously. Conclusions Patients with hypophosphatemic osteomalacia should be thoroughly investigated for TIO. 99mTc-Oct and other imaging examinations can effectively locate the tumors. Once the hidden tumor is found and excised, the patient will recover and enjoy normal life with normalized Pi concentrations and marked improvement of symptoms.

Objective:To explore the intervention effect of sensorimotor training on cognitive function, balance and fall risk of elderly patients with schizophrenia.Methods:The 60 hospitalized elderly schizophrenic patients in Wuxi Mental Health Center were randomly divided into experimental group and control group from June to September 2021, with 30 cases in each group. The control group implemented traditional exercise on the basis of routine nursing. The experimental group received 8-week and 24 times sensorimotor training on the basis of the routine nursing. The Chinese version of the Mini Mental State Examination (MMSE) was used to assess the cognitive level of patients, the Modified Morse Fall Scale (MMFS) was used to assess the risk of falls, and the Berg Balance Scale (BBS) was used to assess the balance function.Results:After 8 weeks of intervention, the total score of MMSE was (26.72 ± 1.71), higher than the total score of the control group (22.36 ± 1.93), the factor scores of temporal orientation, spatial orientation, recollection, attention and calculation, memory and language ability in the experimental group were (4.90 ± 0.31), (4.72 ± 0.53), (2.86 ± 0.35), (4.66 ± 0.61), (2.83 ± 0.47), (6.76 ± 1.09), higher than scores of the control group (4.36 ± 0.56), (3.93 ± 0.66), (2.57 ± 0.50), (3.64 ± 1.03), (2.18 ± 0.67), (5.68 ± 1.02), and the difference was statistically significant( t values were 2.53-9.06, all P< 0.05). The total score of MMFS in the experimental group was (5.93 ± 1.49), which was lower than that in the control group (8.75 ± 2.30). The difference was statistically significant ( t=-5.51, P<0.01). The total score of BBS in the experimental group was (38.83 ± 1.71), which was higher than that in the control group (30.89 ± 1.93). The difference was statistically significant ( t=16.43, P<0.01). Conclusions:Sensorimotor training can improve the level of balance, cognitive function and reduce the risk of falls in elderly patients with schizophrenia.

Objective To study whether preoperative serum thyrotropin ( TSH) concentration can be used for risk prediction of papillary thyroid microcarcinoma ( PTMC ) . Methods The cohort of this retrospective study consisted of 1 707 patients who underwent surgery on thyroid nodules at Chinese PLA General Hospital from October 1999toFebruary2011. 37.32%(n=637)ofthesepatientssufferedfromdifferentiatedthyroidcancer(DTC),and 14. 18%(n=242) of patients with DTC suffered from PTMC. Results (1) The mean TSH level in patients with DTC was significantly higher than that in patients with benign thyroid nodules [(1. 99(1. 25-3. 19) vs 1. 48 (0. 85-2. 32) mU/L, P<0. 01]. DTC with diameter greater than 10 mm had higher serum TSH level compared with that in benign thyroid nodules[2. 04(1. 26-3. 36) vs 1. 45(0. 83-2. 30), P<0. 01]. Serum TSH level was not significantly raised in cases where-as the diameter of tumor was 10 mm or less. (2) With the increasing level of TSH, the prevalence of DTC and tumours with diameter greater than 10 mm rose significantly, but the increasing trend was not significant in PTMC. (3) Raised TSH level was an independent risk factor of DTC based on Binary logistic regression. Conclusions Serum TSH is an independent risk predictor of DTC, it is an independent risk predictor of the diameter of DTC greater than 10 mm, but it is not a good risk predictor in PTMC.
