Innovative insights: ITLN1 modulates renal injury in response to radiation.

Radiation-induced kidney injury is a common side effect of radiotherapy, as the pelvic region is in close proximity to the kidneys, posing a risk of inducing radiation-induced kidney injury when treating any pelvic malignancies with radiotherapy. This type of injury typically manifests as chronic kidney disease a few months after radiotherapy, with the potential to progress to end-stage renal disease. Radiation-induced damage involves various components of the kidney, including glomeruli, tubules, interstitium, and extracellular matrix. Therefore, investigating its molecular mechanisms is crucial. In this study, we extensively searched literature databases, selecting recent transcriptomic studies related to acute kidney injury (AKI) published in the past decade. We downloaded the raw RNA sequencing datasets GSE30718 and GSE66494 related to AKI from the GEO database and identified that intestinal-type lectin ITLN1 plays a significant role in regulating radiation-induced kidney injury in rats. Differential gene analysis was performed using chip data from the GEO database, and further bioinformatics analysis identified 13 genes that may be involved in regulating kidney injury, with ITLN1 being the most relevant to kidney damage, thus selected as the target gene for this study. Subsequently, a rat model of radiation-induced kidney injury was established for experimental validation, assessing kidney tissue morphology and injury extent through staining observation and immunohistochemical staining. The protective effect of ITLN1 on kidney function was evaluated by measuring changes in rat body weight and blood pressure, serum kidney injury markers, and kidney structure. The experimental results indicate that overexpression of ITLN1 can improve kidney function in rats with radiation-induced kidney injury by activating the Akt/GSK-3ß/Nrf2 signaling pathway, suppressing oxidative stress, cell apoptosis, inflammation, cellular senescence, and fibrosis. This study highlights the significant role of ITLN1 in regulating kidney injury, providing a novel target for future treatments of radiation-induced kidney injury.

Role of TRP Channels in Metabolism-Related Diseases.

Metabolic syndrome (MetS), with its high prevalence and significant impact on cardiovascular disease, poses a substantial threat to human health. The early identification of pathological abnormalities related to MetS and prevention of the risk of associated diseases is of paramount importance. Transient Receptor Potential (TRP) channels, a type of nonselective cation channel, are expressed in a variety of tissues and have been implicated in the onset and progression of numerous metabolism-related diseases. This study aims to review and discuss the expression and function of TRP channels in metabolism-related tissues and blood vessels, and to elucidate the interactions and mechanisms between TRP channels and metabolism-related diseases. A comprehensive literature search was conducted using keywords such as TRP channels, metabolic syndrome, pancreas, liver, oxidative stress, diabetes, hypertension, and atherosclerosis across various academic databases including PubMed, Google Scholar, Elsevier, Web of Science, and CNKI. Our review of the current research suggests that TRP channels may be involved in the development of metabolism-related diseases by regulating insulin secretion and release, lipid metabolism, vascular functional activity, oxidative stress, and inflammatory response. TRP channels, as nonselective cation channels, play pivotal roles in sensing various intra- and extracellular stimuli and regulating ion homeostasis by osmosis. They present potential new targets for the diagnosis or treatment of metabolism-related diseases.

Effects of stroke on the intestinal biota in diabetic mice and type 2 diabetic patient biota.

AIMS: The intestinal biota, known for its colonization of the human intestine and its modulation of host pathophysiological responses through the immune and endocrine systems, has gained substantial interest in recent years due to its notable correlation with diabetes and stroke. METHODS: In order to examine this association, a comparative study was conducted on the intestinal biota and blood samples obtained from mouse models and type 2 diabetic patients with and without stroke complications. Advanced techniques, such as high-throughput sequencing and enzyme-linked immunosorbent assay were employed to identify the differences in the intestinal biota and blood indices of mouse models and patients. RESULTS: At the phylum level, the dominant gut bacteria identified in patients with diabetes mellitus and stroke were Firmicutes, Bacteroidetes, and Proteobacteria. It was noteworthy that the relative abundance of Bacteroides at the genus level was significantly diminished in the DB-PT group (photothrombotic diabetes mice) as compared to the DB group (diabetesmice). This result was consistent with observations in human samples. Additionally, significant variations were detected in lipid proteins, specifically APOA4, in diabetic patients with and without stroke. CONCLUSIONS: Stroke can diminish the abundance and diversity of intestinal biota, potentially correlating with lipid proteins in patients with diabetes.

High-expressed PTPN1 promotes tumor proliferation signature in human hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a highly prevalent malignant tumor that is associated with substantial morbidity and mortality rates. Despite the progress made in diagnostic technology, the survival rate of HCC patients remains unsatisfactory due to the complex nature and extensive metastasis of the disease. Consequently, the discovery of new molecular targets is of great practical significance for the diagnosis and treatment of HCC. Protein tyrosine phosphatases (PTPs) play a crucial role in cell signal transduction by catalyzing the dephosphorylation of tyrosine residues in proteins. The present study has revealed that the upregulation of protein tyrosine phosphatase non-receptor type 1 (PTPN1) is a characteristic feature of HCC and is associated with a poor prognosis. Additionally, our investigation into the functional roles of PTPN1-regulated genes in HCC has demonstrated that alterations in PTPN1 expression disrupt normal cell cycle progression metabolism. Additionally, the capacity for proliferation and migration of HCC cells was notably diminished subsequent to PTPN1 silencing, resulting in the prevention of cell entry into the S phase from the G1 phase. Our investigation indicates that PTPN1 may facilitate the onset and progression of HCC by disrupting the cell cycle, thereby presenting a promising molecular target for the diagnosis and treatment of liver cancer.

TRPs in Ovarian Serous Cystadenocarcinoma: The Expression Patterns, Prognostic Roles, and Potential Therapeutic Targets.

Ovarian cancer (usually ovarian serous cystadenocarcinoma, or OV) is the fifth leading cause of cancer-related deaths in women, with more than 184,000 deaths reported worldwide annually, and is a highly malignant carcinoma. However, the mechanism of etiology remains unclear. The lack of prognostic and diagnostic biomarkers is a main limitation for clinical diagnosis and treatment. The transient receptor potential (TRP) channels play essential roles in the occurrence and development of cancers which may have the potential as a therapeutic target for OV. In our study, we used bioinformatic methods to study the potential effect and function of the TRP family in patients with OV. Differential expression analysis showed that the expression of TRPC7, TRPV4, and other TRP family members was significantly different between tumor and normal tissues. Through survival analysis, we screened out that the high expression of TRPC7, TRPV4, and TRPM (2,4,8) was negatively correlated with the prognosis of patients. In contrast, the low expression of TRPM3 was negatively associated with the prognosis. Cox regression analysis further indicated that TRPV4 was OV's most likely therapeutic target. Finally, we conducted mRNA expression analysis, functional enrichment analysis, and immune infiltration analysis to confirm that TRPV4 was the most convincing therapeutic target of OV.

Zinc Finger Proteins in Neuro-Related Diseases Progression.

Zinc finger proteins (ZNF) are among the most abundant proteins in eukaryotic genomes. It contains several zinc finger domains that can selectively bind to certain DNA or RNA and associate with proteins, therefore, ZNF can regulate gene expression at the transcriptional and translational levels. In terms of neurological diseases, numerous studies have shown that many ZNF are associated with neurological diseases. The purpose of this review is to summarize the types and roles of ZNF in neuropsychiatric disorders. We will describe the structure and classification of ZNF, then focus on the pathophysiological role of ZNF in neuro-related diseases and summarize the mechanism of action of ZNF in neuro-related diseases.

PTPN5 promotes follicle-stimulating hormone secretion through regulating intracellular calcium homeostasis.

Protein tyrosine phosphatase non-receptor type 5 (PTPN5), also called striatal-enriched protein tyrosine phosphatase (STEP), is highly expressed in neurons of the basal ganglia, hippocampus, cortex, and related structures, also in the pituitary. Gonadotropins are the key regulator of the reproduction in mammals. In this study, PTPN5 is detected to express in murine pituitary in a developmental manner. Moreover, the expression of PTPN5 in the pituitary is heavily reduced after ovary removal. Follicle-stimulating hormone (FSH) secretion in gonadotropes is regulated by PTPN5 via binding GnRH to GnRH-R. Two parallel signaling pathways, Gs-protein kinase A (PKA)-PTPN5 and Gq-phospholipases C (PLC)-p38 MAPK-PTPN5, cooperatively regulate GnRH-induced FSH secretion. We also show that influx of Ca2+ activates the Ca2+ -dependent phosphatase calcineurin, leading to the phosphorylation and activation of PTPN5. The intracellular release of Ca2+ is reduced via TC2153. In conclusion, blocking or knocking out of PTPN5 reduces the release of FSH in whole pituitary. Mechanically, PTPN5 regulates gonadotropes' function through regulating intracellular calcium homeostasis.

Massive renal urothelial carcinoma with renal vein tumor thrombus, pancreatic infiltration and adrenal metastasis: A case report.

A 49-year-old female patient presented with a massive left renal tumor, recurrent left flank pain and gross hematuria. The tumor was accompanied by a renal vein tumor thrombus, pancreatic infiltration and a solitary adrenal metastasis. Radical nephrectomy, distal pancreatectomy, ipsilateral adrenalectomy and splenectomy were performed. Histopathological examination suggested high-grade urothelial carcinoma (UC); however, tumor recurrence and multiple metastases were detected only 3 months after the surgery, and the patient succumbed during follow-up 1 month later. To the best of our knowledge, this is the first case of renal UC of such advanced stage with renal vein tumor thrombus, pancreatic infiltration and a solitary adrenal metastasis.

A systematic review and meta-analysis of comparative studies assessing the efficacy of luteinizing hormone-releasing hormone therapy for children with cryptorchidism.

PURPOSE: To assess the efficacy of intranasal luteinizing hormone-releasing hormone (LHRH) therapy for cryptorchidism. MATERIALS AND METHODS: Eligible studies were identified by two reviewers using PubMed, Embase, and Web of Science databases. Primary outcomes were complete testicular descent rate, complete testicular descent rate for nonpalpable testis, and pre-scrotal and inguinal testis. Secondary outcomes included testicular descent with different medicines strategy and a subgroup analysis. RESULTS: Pooled data including the 1255 undescended testes showed that complete testicular descent rate was 20.9 % in LHRH group versus 5.6 % in the placebo group, which was significantly different [relative risk (RR) 3.94, 95 % confidence interval (CI) 2.14-7.28, P < 0.0001]. There was also a significant difference in the incidence of pre-scrotal and inguinal position testis descent, with 22.8 % in the LHRH group versus 3.6 % in the placebo group (RR 5.79, 95 % CI 2.94-11.39, P < 0.00001). However, side effects were more frequent in the LHRH group (RR 2.61, 95 % CI 1.52-4.49, P = 0.0005). There were no significant differences for nonpalpable testes. CONCLUSIONS: LHRH had significant benefits on testicular descent, particularly for inguinal and pre-scrotal testes, which was also accompanied by temporary slight side effects.

Supine versus Prone Position during Extracorporeal Shockwave Lithotripsy for Treating Distal Ureteral Calculi: A Systematic Review and Meta-Analysis.

PURPOSE: We aimed at evaluating the efficacy of extracorporeal shockwave lithotripsy (SWL) for treating distal ureteral calculi performed in supine vs. prone position. MATERIALS AND METHODS: Eligible studies were identified by 2 reviewers using PubMed, Embase, and Web of Science databases. Outcomes included stone-free rate after the first and the final SWL session, the mean number of shocks per SWL session, the mean percentage of power used in the first SWL session, and the mean number of SWL sessions per patient. RESULTS: Pooled data among the 647 included patients showed that supine SWL was associated with a significantly higher stone-free rate than prone SWL. This difference was consistent for both the first SWL session (OR 4.17; 95% CI 2.53-6.87; p < 0.00001) and the final session (OR 3.02; 95% CI 1.96-4.67; p < 0.00001). No differences in the mean number of shocks per SWL session, the mean percentage of power used in the first SWL session, and the mean number of SWL sessions per patient were observed between the positions. SWL complications were infrequent and the incidence was insufficient for further analysis. CONCLUSION: SWL is safe and effective for the management of distal ureteral calculi, and supine SWL is more effective than prone SWL for achieving a stone-free status.

Non-functioning paraganglioma occurring in the urinary bladder: A case report and review of the literature.

Paraganglioma, also termed extra-adrenal pheochromocytoma, may be observed at the base of the skull and neck as well as within the mediastinum and periaortic region. The clinical symptoms of paraganglioma of the urinary bladder include intermittent hypertensive attacks, micturition, headaches and palpitations due to high catecholamine levels; these types of paragangliomas are extremely rare. However, certain bladder paragangliomas do not present with any of these symptoms; thus, surgeons are not pre-warned on how to prepare for their resection. Surgery to remove pheochromocytomas may therefore result in an intraoperative hypertensive crisis and increase the mortality rate. This infrequent type of paraganglioma is only recognized through histological examination following surgery. The current study reports the case of a 61-year-old male with urinary bladder paraganglioma. The patient presented with hypertension, which was controlled to within a normal range using diovan and norvasc treatment; in addition, the patient's blood pressure was not altered with urination or postural changes. The patient was not administered an α-blocking agent or a blood volume expander prior to the surgery, and during the partial cystectomy no hypertensive crisis occurred.

Systemic lupus erythematosus accompanying with renal tuberculosis: a case report.

A 26-year-old woman, with a six-year history of well-controlled systemic lupus erythematosus (SLE), complained of urinary frequency and urgency. After failure of commonly-used antibiotic therapy, mycobacterium tuberculosis was cultured from her urine and renal tuberculosis (TB) was diagnosed. However, she underwent right nephrectomy after the combination therapies of prednisone for SLE and anti-tuberculosis treatment for renal TB failed. To our knowledge, SLE accompanying renal TB is rare, and such a rapid deterioration in renal function has never been reported.

[Trans-lumbar-and-peritoneally joint approach for laparoscopic removal of large adrenal neoplasms].

OBJECTIVE: To explore the safety and efficacy of translumbar-and-peritoneally joint (TLPJ) approach for laparoscopic dissection of large neoplasms from adrenal glands. METHODS: Sixty patients with diameters > or = 6.0 cm adrenal neoplasms were recruited in this study. Of the participants, 30 were given transperitoneally laparoscopic adenectomy and 30 were given TLPJ approach. We compared the basic characteristics of the patients, as well as their conditions during and after operations. RESULTS: The two groups of patients had similar characteristics. No significant differences were found between the two approaches in terms of conversion to open surgery, estimated blood loss, transfusion, operating time, side injury, fluctuations of heart rate and blood pressure, and vascular accidents (P>0.05), although slight, but not significant, advantages were shown in the TLPJ patients on starting food intake and physical activities. Similar results were also found .in drainage volume, time to remove drainage, length of hospital stay, usage of analgesic, fever incidence, infection and intestinal obstruction etc (P>0.05). Above all, no significant differences were found between the two groups in recurrence, metastasis and overall survival rates (P>0.05). CONCLUSION: Laparoscopic surgery with TLPJ approach, translumbar combined with entirely side peritoneum opened, is safe and efficient compared with the traditional transperitoneal approach for patients with large adrenal neoplasms.

Diagnosis and treatment of adrenal medullary hyperplasia: experience from 12 cases.

Objective. To dissect the characteristics of adrenal medullary hyperplasia (AMH) and share our experience of diagnosis and treatment of AMH. Methods. From 1999 to 2013, 12 cases of AMH have been pathologically diagnosed after operation in our hospital. The clinical characteristics, process of diagnosis, treatment, and prognosis during follow-up of all patients are summarized retrospectively. Results. Four cases were trended to be AMH and 6 cases were trended to be pheochromocytoma before operation; moreover, the other two patients were diagnosed accidentally. All patients, except for the patient with mucinous tubular and spindle cell carcinoma of left kidney by open surgery, experienced a smooth laparoscopic adrenalectomy, including 2 with radical nephrectomy, 10 of which experienced unilateral adrenalectomy, 1 was bilaterally partial adrenalectomy, and the remaining one was unilaterally complete removal and then 2/3 partially contralateral excision. After a medium follow-up of 6.5 years, it demonstrated a satisfactory outcome of 8 cured patients and 4 symptomatic improved patients. Conclusions. AMH presents a mimicking morphology and clinical manifestation with pheochromocytoma. Surgery could be the only effective choice for the treatment of AMH and showed a preferable prognosis after a quite long follow-up.

Simulated physiological stretch-induced proliferation of human bladder smooth muscle cells is regulated by MMPs.

Mechanical stimulation is an essential factor for organisms to develop normally. In bladder development matrix metalloproteinases (MMPs) play an important role through structure remodeling and regulating the cell proliferation. In this study, we investigated the simulated physiological stretch induced proliferation of HBSMCs; MMPs/TIMPs expression in stretch and non-stretch groups. HBSMCs were exposed to cyclic stretch with defined parameters (5%, 10% and 15% elongation). The expression of MMPs and TIMPs in each parameter and non-stretch groups was examined at the transcriptional and translational levels respectively. 5-Ethynyl-2'-deoxyuridine (EdU) assay was used to assess cell proliferation. In the presence of the broad spectrum MMPs inhibitor (Batimastat), cells proliferation, MMPs and tissue inhibitors of metalloproteinases (TIMPs) expression were assessed again. Compared with non-stretch group, HBSMCs in stretch groups showed higher proliferation. The expression of MMP-1, 2, 3, 7 was up-regulated in stretch groups, and it remained at the same high level in 10% and 15% stretch groups. TIMP-1, 2 expression only increased under 15% stretch. Stretch resulted in elevated cell proliferation was abolished by Batimastat. In conclusion, the proliferation of HBSMCs induced by stretch was resulted from the stretch-induced MMPs expression and release.

The role of mirabegron in overactive bladder: a systematic review and meta-analysis.

OBJECTIVE: To present a systematic review assessing the efficacy and safety of mirabegron for overactive bladder (OAB). MATERIALS AND METHODS: A literature search was performed using the Cochrane Library, MEDLINE, EMBASE and Science Citation Index Expanded. The literature reviewed included meta-analyses, randomized and nonrandomized prospective studies. We utilized mean difference (MD) to measure the mean number of incontinence episodes and the mean number of micturitions, and OAB questionnaire (OAB-q) and odds ratio (OR) to measure adverse events rates. We used the Cochrane Collaboration's Review Manager 5.1 software for statistical analysis. RESULTS: We identified six publications that strictly met our eligibility criteria. Meta-analysis of extractable data showed that mirabegron was more effective than placebo in treating OAB despite different drug dosages in the efficacy end points: mean number of incontinence episodes per 24 h (MD -0.54; 95% CI -0.63, -0.45; p = 0.001), mean number of micturitions per 24 h (MD -0.55; 95% CI -0.63, -0.47; p = 0.001), OAB-q (MD -4.49; 95% CI -6.27, -2.71; p = 0.001) and adverse events (OR 0.99; 95% CI 0.83, 1.19; p = 0.92). When compared to tolterodine, mirabegron was more effective in terms of mean number of incontinence episodes per 24 h (MD -0.25; 95% CI -0.43, -0.06; p = 0.009). However, there were no differences between mirabegron and tolterodine in mean number of micturitions per 24 h (MD -0.17; 95% CI -0.35, 0.01; p = 0.07) and OAB-q (MD -1.09; 95% CI -2.51, 0.33; p = 0.13). Mirabegron also had a lower adverse reaction rate (OR 0.9; 95% CI 0.8, 1.0; p = 0.04). CONCLUSIONS: In this diverse population, mirabegron was an effective and safe pharmacologic therapy for OAB.

The role of statins in erectile dysfunction: a systematic review and meta-analysis.

To evaluate the effect of statins for erectile dysfunction (ED), a systematic review of the literature was conducted in the Cochrane Library, Embase and PubMed from the inception of each database to June 2013. Only randomized controlled trials (RCTs) comparing treatment for ED with statins were identified. Placebo RCTs with the International Index of Erectile Function (IIEF) as the outcome measure were eligible for meta-analysis. A total of seven RCTs including two statins with a total of 586 patients strictly met our criteria for systematic review and five of them qualified for the meta-analysis. A meta-analysis using a random effects model showed that statins were associated with a significant increase in IIEF-5 scores (mean difference (MD): 3.27; 95% confidential interval (CI):1.51 to 5.02; P < 0.01) and an overall improvement of lipid profiles including total cholesterol (MD: -1.08; 95% CI: -1.68 to -0.48; P < 0.01), low-density lipoprotein (LDL) cholesterol (MD: -1.43; 95% CI: -2.07 to -0.79; P < 0.01), high-density lipoprotein (HDL) cholesterol (MD: 0.24; 95% CI: 0.13 to 0.35; P < 0.01) and triglycerides (TGs) (MD: -0.55; 95% CI: -0.61 to -0.48; P < 0.01). In summary, our study revealed positive consequences of these lipid-lowering drugs on erectile function, especially for nonresponders to phosphodiesterase type 5 inhibitors (PDE5Is). However, it has been reported that statin therapy may reduce levels of testosterone and aggravate symptoms of ED. Therefore, larger, well-designed RCTs are needed to investigate the double-edged role of statins in the treatment of ED.

A systematic review and meta-analysis of comparative studies on the efficacy of extended pelvic lymph node dissection in patients with clinically localized prostatic carcinoma.

PURPOSE: Pelvic lymph node dissection (PLND) has been performed during radical prostatectomy in nearly all patients with clinically localized prostatic carcinoma (PCa), while the specific regions that needed to be removed demonstrated bifurcation among urologist. However, clinical studies comparing extended PLND (ePLND) with standard PLND (sPLND) and limited PLND (lPLND) reveal conflicting, or even opposing results. METHODS: All controlled trials comparing ePLND with sPLND or lPLND were identified through comprehensive searches of the PubMed, Cochrane Library and Embase databases. A systematic review and meta-analysis of these studies were then performed. RESULTS: Eighteen studies with a total of 8,914 patients were included. Regardless of being compared with sPLND or lPLND, ePLND significantly improved LN retrieval [ePLND vs. sPLND: weighted mean difference (WMD) 11.93, 95 % confidence interval (CI) 9.91-13.95, p < 0.00001; ePLND vs. lPLND: WMD 8.27, 95 % CI 3.53-13.01, p = 0.0006] and the detection of more LNs positive of metastasis [risk ratio (RR) 3.51, 95 % CI 2.14-5.75, p < 0.00001; RR 3.50, 95 % CI 2.20-5.55, p < 0.00001, respectively]. EPLND decreased the complication rate, but the differences were not statistically significant (RR 1.52, 95 % CI 0.87-2.65, p = 0.14; RR 1.52, 95 % CI 0.67-3.45, p = 0.32, respectively). Operating time, estimated blood loss, length of hospital stay and biochemical recurrence (BCR) were statistically insignificant between techniques. CONCLUSIONS: ePLND shows benefits associated with increased LNs yield, LNs positivity, and safety, significantly with no risk of side effects. However, ePLND did not decrease BCR. Additional high-quality, well-designed randomized controlled trials and comparative studies with long-term follow-up results are required to define the optimal procedure for patients with clinically localized PCa.

An extremely rare case of unilateral renal arterial and venous multiple deformity, combined with duplex pelvis and malrotation.

Renal vascular deformity (RVD) happens during the embryonic period when kidneys ascend into the lumber region. However, the exact etiology of this deformity remains unknown. RVD is not a rare congenital anomaly in urology as many cases with vascular deformity have been reported.However, no case has been reported with unilateral kidney almost in the normal position, but with several different branches of ectopic arteries-one even receiving the arterial supply from the contralateral iliac artery-and ectopic veins, one of which forms a collateral circulation with the portal vein. Moreover, it is quite interesting that this case of RVD is combined with another abnormality-duplex pelvis and renal malrotation. We will present this extremely rare case of multiple malformation of the right renal vascular deformity combined with duplex pelvis and malrotation.

Perioperative Endocrine Therapy for Patients with Cushing's Syndrome Undergoing Retroperitoneal Laparoscopic Adrenalectomy.

Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET) for patients with Cushing's syndrome (CS) undergoing retroperitoneal laparoscopic adrenalectomy (RLA). Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP), levels of serum cortisol, adrenocorticotropin (ACTH), blood glucose, and electrolytes, were acquired and analyzed. Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient's symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months), except for one patient undergoing bilateral adrenalectomy. Conclusions. This perioperative endocrine therapy for patients with Cushing's syndrome (mainly for adrenocortical adenoma) undergoing retro-laparoscopic adrenalectomy is both effective and safe.
