Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.

[Objective]To evaluate the efficacy and safety of total oral regimens containing pomalidomide as a second-line treatment strategy in multiple myeloma.[Methods]A total of 22 patients with multiple myeloma placed on total oral regimens containing pomalidomide as a second-line therapy from March 2020 to December 2023 were retrospectively analyzed to evaluate the treatment response,survival and safety.[Results]The median age of the 22 patients was 71.5 years old. The total oral treatment regimens containing pomalidomide included IPD (7 cases),PCD (11 cases),XPD (2 cases),and PD (2 cases). The median number of treatment cycles was 14. Among the 13 patients with prior lenalidomide exposure,ORR was 53.85%,of which 23.08% was ≥VGPR. In 9 patients without prior lenalidomide exposure,the ORR was 77.78%,and of which 55.56% was ≥VGPR. There was no significant difference in ORR between these two groups (P=0.38). In 12 patients with high genetic risk,the ORR was 50%,and ≥VGPR was 16.67%. The median follow-up time was 10.6 months. Disease progressed in 10 patients and death occurred in 6 patients of them. The median progression free survival (PFS) was not reached (not reached and 10.6 months in non-lenalidomide-exposure patients or lenalidomide-exposure patients,respectively).The high grade treatment-related adverse events (AEs)(≥3 ) were reported in 18.18% patients,including granulocytopenia,thrombocytopenia,and pulmonary infection. There was no treatment-related death.[Conclusion]Total oral regimens containing pomalidomide as a second-line therapy is generally effective and safe for multiple myeloma patients.

Objective:To investigate risk factors for decompressive craniectomy (DC) after endovascular therapy (EVT) in patients with acute anterior circulation ischemic stroke.Methods:Patients underwent EVT due to acute anterior circulation large vessel occlusion in Liaocheng Brain Hospital from January 2018 to January 2020 were retrospectively included. They were divided into DC group and non-DC group. Univariate and multivariate logistic regression analyses were used to determine risk factors for DC after EVT. Results:A total of 207 patients were enrolled, 126 were male (60.87%), and their age was 66.22±11.24 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 19.84±9.20, and the Alberta Stroke Program Early CT Score (ASPECTS) was 7.98±0.66. The immediate postoperative modified Treatment In Cerebral Ischemia (mTICI) blood flow grade in seven patients (5.80%) was ≤2a, 30 (14.49%) experienced hemorrhagic transformation (HT) after procedure, and 28 (13.5%) received DC. There were statistically significant differences between the DC group and the non-DC group in terms of past stroke history, preoperative NIHSS score and ASPECTS, vascular occlusion site, EVT time, immediate postoperative mTICI ≤2a, and HT (all P<0.05). Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [ OR] 3.202, 95% confidence interval [ CI] 1.335-9.796; P=0.011), previous stroke history ( OR 2.655, 95% CI 1.016-6.938; P=0.046), high preoperative NIHSS score ( OR 1.074, 95% CI 1.026-1.124; P=0.002), internal carotid artery occlusion ( OR 4.268, 95% CI 1.399-13.024; P=0.011), longer EVT time ( OR 1.010, 95% CI 1.003-1.016; P=0.003), mTICI grade ≤2a ( OR 5.342, 95% CI 1.565-18.227; P=0.007) and postoperative HT ( OR 3.036, 95% CI 1.024-9.004; P=0.045) were independent risk factors for DC. Conclusions:It is not uncommon for patients with acute anterior circulation ischemic stroke to need DC after EVT. Previous stroke history, atrial fibrillation, high baseline NIHSS score, internal carotid artery occlusion, prolonged blood EVT time, mTICI grade ≤2a and postoperative HT are independent predictors of needing DC after EVT.

Trauma has the characteristics of complex disease, high disability rate and fatality rate, which adds difficulty to treatment. Due to the limitation of medical conditions and untimely allocation of resources, the current trauma treatment modes still have shortcomings such as low first aid efficiency and irregular application, and hence the treatment is facing enormous challenges. In the process of trauma treatment, a large amount of dynamic data that are valuable for disease diagnosis and treatment will be generated. Big data and artificial intelligence technology is an algorithm that can reasonably predict or estimate the given data based on large-scale data collection, and has been applied to trauma treatment modes. The efficient and accurate statistical analysis of big data and innovative medical technology directions such as machine learning, planning and decision-making not only improve the efficiency and safety of trauma treatment, but also reduce the workload of clinicians, making up for the shortcomings of traditional trauma treatment modes. The authors mainly review the application of big data and artificial intelligence technology in pre-hospital first aid and in-hospital diagnosis and treatment for trauma patients, in order to provide a reference for trauma treatment.

Objective:To explores the clinical efficacy and safety of carotid endarterectomy in patients with high bifurcation carotid artery stenosis.Methods:A total of 169 patients with carotid artery stenosis (147 patients with non-high bifurcation carotid artery stenosis and 22 patients with high bifurcation carotid artery stenosis), underwent carotid endarterectomy under surgical microscope in our hospital from January 2017 to January 2020, were included in the study. Patients with high bifurcation carotid artery stenosis were operated by cutting off the posterior abdomen of the digastric muscle to assist in exposing the distal end of the internal carotid artery plaque. Cervical CTA/DSA examination was performed within one week of surgery to confirm whether carotid artery stenosis was relieved; ultrasound examination of cervical vessels was performed 6 months and 1 year after surgery to determine whether restenosis was appeared in the carotid artery. The surgical efficacy, perioperative complications and re-examination results were compared between the two groups.Results:Postoperative carotid artery stenosis was relieved in both groups. The proportions of new cerebral infarction and temporary neurological impairment between the two groups (4.5% vs. 2.0%; 9.1% vs. 3.4%) showed no significant differences ( P>0.05). Carotid artery restenosis was not found in both groups. There was no obvious functional abnormality in the digastric muscles of patients with high bifurcation carotid stenosis. Conclusion:Cutting off the posterior abdomen of the digastric muscle during carotid endarterectomy can better expose the distal end of the internal carotid plaque in patients with high bifurcation carotid stenosis, and provide convenience for effective relief of carotid artery stenosis with high safety.

Objective:To explore the clinical value of 68Ga-pentixafor PET/CT targeting for CXCR4 in the diagnosis and prognosis evaluation of primary aldosteronism (PA). Methods:Retrospective analysis was performed on information of 72 patients diagnosed with PA who received operations according to the results of 68Ga-pentixafor PET/CT in our hospital. There were 37 males and 35 females, with the average age of (48.3±9.5) years old. The average lesion diameter was (1.60 ± 0.54)cm. The preoperative systolic and diastolic blood pressure were (177.3 ± 23.9)mmHg and (107.6 ± 13.2)mmHg, respectively. The average preoperative potassium level was (2.62 ± 0.56)mmol/L. The average aldosterone concentration was (17.98 ± 4.66)ng/dl, and the median plasma renin activity was 0.01 (0.01, 0.09) ng/(ml·h). All patients underwent 68Ga-pentixafor PET/CT examination, which lead to the decision of surgical strategies. For those patients with single lesion, multiple lesions in one side or positive lesion in one side but negative in the opposite side, surgical resection of the positive side lesion or total adrenalectomy was considered. For those patients with bilateral positive lesions, surgical resection of the side with more significant positive lesions or total adrenalectomy was considered. For those with negative multiple lesions, the surgical strategy was designed according to the results of CT examination or AVS. The positive rate of 68Ga-pentixafor PET/CT and its relationship with the clinical characteristics and prognosis of patients were analyzed. Results:The results of 68Ga-pentixafor PET/CT were positive in 62 of 72 patients diagnosed with PA (86.1%), and the median SUVmax value was 11.1 (7.1, 16.2). The SUVmax value was positively correlated with the maximum diameter of adrenal lesion ( r=0.468) and negatively correlated with blood potassium levels ( r=-0.437), while not significantly correlated with other clinical characteristics. The positive rate of adenoma by 68Ga-pentixafor PET/CT was higher than that of nodular hyperplasia [90.5%(57/63) vs. 55.6%(5/9), P=0.018], and the SUVmax value in adenoma was also higher than that in nodular hyperplasia [11.9(7.8, 16.2) vs. 4.3(3.4, 11.3), P=0.022]. 32 cases were cured after operations, and 37 cases were improved. And 3 cases were not cured. The SUVmax value of lesions in the cured patients was higher than that in the improved patients [15.4(8.1, 22.7) vs. 10.1(6.8, 13.3), P=0.013]. Among 59 cases of PA patients with single adrenal lesions, 50 cases represented positive results of 68Ga-pentixafor PET/CT. 23 cases in 50 positive cases were cured and 27 cases were improved after resection of positive lesions. In the 13 PA patients with multiple adrenal lesions who underwent surgery according to the results of 68Ga-pentixafor PET/CT, 12 patients (92.3%) showed postoperative prognosis in line with preoperative expectations. Conclusions:68Ga-pentixafor PET/CT showed high positive rate in the diagnosis of PA, especially for adenoma.The SUVmax value of the adrenal lesion was correlated with the blood potassium level, the size of the lesion and the postoperative prognosis. In addition, 68Ga-pentixafor PET/CT could effectively guide the surgical decision of PA.

Objective:To comprehensively analyze the expression profile of circular RNA (circRNA) and construct competing endogenous RNA (ceRNA) regulatory networks in tuberous sclerosis complex related renal angiomyolipoma (TSC-RAML).Methods:According to the diagnostic criteria of TSC determined by the international consensus group on tuberous sclerosis in 2012, tumor tissues and paired normal renal tissues of 3 patients with TSC-RAML who were diagnosed in our hospital from January 2017 to January 2019 were collected. The circRNA, miRNA and mRNA of 3 paired samples were detected by circRNA, miRNA chip technology and next generation sequencing respectively, and the differential molecules were determined. Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed based on differential mRNA molecules and host genes of circRNA. Based on differential circRNA, miRNA and mRNA, up-regulated and down-regulated ceRNA regulatory networks were established.Results:A total of 330 up-regulated and 336 down-regulated differential circRNA, 8 up-regulated and 7 down-regulated miRNA, 800 up-regulated and 1130 down-regulated mRNA were screened. Through GO and KEGG enrichment analysis, many pathways including lipid metabolism, focal adhesion and mineral absorption were abnormally altered. Finally, the up-regualted ceRNA network led by hsa_circ_0092022, hsa_circ_0076859 and hsa_circ_0033388 and down-regulated network led by hsa_circ_0000374, hsa_circ_0000141, hsa_circ_0072665, hsa_circ_0009503 and hsa_circ_0000009 were constructed.Conclusions:There were many differentially expressed circRNA between TSC-RAML and paired normal renal tissues. ceRNA regulatory networks may be involved in the occurrence and development of TSC-RAML.

PURPOSE: Evidence on the contribution of genes to the hereditary predisposition to pulmonary arterial hypertension (PAH) is limited. MATERIALS AND METHODS: In this study, we hypothesized that single nucleotide variants in vascular endothelial growth factor (VEGF) gene may alter gene function and expression and may be associated with PAH risk. Five putatively functional loci (rs699947C>A and rs833061T>C in the promoter, rs3025040C>T, rs10434G>A and rs3025053G>A in the 3'-UTR) in the VEGF gene were genotyped and analyzed in a retrospective study of 587 patients with PAH and 736 healthy subjects from southern China. RESULTS: We found that the rs833061T>C polymorphism was significantly associated with PAH risk, while the other single nucleotide polymorphisms were not. Compared to carriers with TT genotype, those with rs833061C variant genotype (CT/CC) had an increased risk of PAH (odds ratio=1.47, 95% confidence interval=1.18–1.83, p=0.001). Functional assays indicated that CT/CC variant genotype had significantly higher mRNA levels of VEGF in peripheral blood mononuclear cells than TT genotype (p=0.021). Luciferase reporter assay indicated that having a C allele conferred a significantly higher transcription activity than that with a T allele. CONCLUSION: Our findings suggest that the functional polymorphism rs833061T>C in VEGF gene promoter modulates VEGF expression and may be a valuable biomarker for predicting PAH susceptibility.
