Aim To investigate the predictive value of lipoprotein(a)[Lp(a)]combined with systemic inflam-matory response index(SIRI)on in-stent restenosis(ISR)after percutaneous coronary intervention(PCI)in patients with coronary heart disease.Methods The clinical data of 770 patients with coronary heart disease who underwent PCI in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Xinjiang Medical University from May 2012 to December 2024 and underwent coronary angiography six months after surgery were collected.According to the imaging re-sults,the patients were divided into ISR group(n=194)and non-ISR group(n=576).Multivariate Logistic regression and random forest model were used to analyze the independent risk factors of ISR.Risk factors included in the analysis were glycated hemoglobin,SIRI,Lp(a),lymphocyte count,apolipoprotein A1(ApoA1)and residual cholesterol.Results The levels of Lp(a)and SIRI in the ISR group were significantly higher than those in the non-ISR group(P＜0.05).ROC curve analysis showed that the area under the curve of the combined indicator of Lp(a)and SIRI was 0.789,which was higher than the 0.652 of the single indicator Lp(a)and 0.778 of SIRI.Conclusion Lp(a)and SIRI are independent risk factors for the occurrence of ISR after PCI,and the combination of Lp(a)and SIRI can better predict the occurrence of ISR.

Objective:To investigate the clinicopathological characteristics of acidophil stem cell pituitary neuroendocrine tumors (PitNET)/adenoma.Methods:Five cases of acidophil stem cell PitNET/adenoma were diagnosed between May 2022 and July 2023 at the Second Hospital of Hebei Medical University, Shijiazhuang, China. The clinicopathological features of the tumor were analyzed by using histology, immunohistochemistry, and electron microscopy. The relevant literature was reviewed.Results:There were 1 male and 4 females, aged from 23 to 69 years. Patient 3 was 55 years old at the time of diagnosis and first surgery, and relapsed 5 years later. The patients′ median age was 32 years. Patients 1 and 5 showed elevated blood prolactin, with various degrees of hormonal symptoms except Patient 3, who showed only tumor compression symptoms. Imaging studies showed that all cases involved the sellar floor. The tumors of Patients 1, 2 and 5 were closely related to the cavernous sinus segment of the internal carotid artery. The tumors exhibited a diffuse growth pattern with chromophobic to slightly acidophilic cytoplasm. A few of tumor cells showed chromophobic cytoplasm. The nucleoli were conspicuous. Intranuclear inclusion bodies and variably-sized clear vacuoles were observed occasionally. Under electron microscope, marked mitochondrial abnormalities were observed, including increased mitochondria number, expanded hypertrophy, and absence of mitochondrial ridge fracture. Some mitochondrial matrices were dense, while some were vacuolated.Conclusions:Acidophil stem cell PitNET/adenoma is a rare type of pituitary adenomas/PitNETs. It often has a more clinically aggressive manner with immature cells, diffuse expression of PIT1, prolactin, and varying degrees of growth hormone expression. Because of the obvious diversity of their clinical hormone status and hormone immune expression, the diagnosis of this type tumor is still a challenge.

According to the International League Against Epilepsy (ILAE) standards, the Newborn Working Group of the ILAE put forward 6 necessary questions about the management of neonatal anti-seizure medication and gave evidence-based recommendations in 2023. The basic framework is systematic review+expert consensus. The clinical recommendations of ILAE guidelines 2023 and the similarities and differences between ILAE guidelines 2023 and ILAE guidelines 2011 were analyzed and interpreted in this paper, in order to provide reference for colleagues involved in neonatal convulsion management in China.

Purpose To investigate the cell components in different tumor lineages of multiple synchronous pituitary neuro-endocrine tumors(PitNETs)/neuroendocrine tumors(MSPs)and to carry out accurate histological typing,which provides an important basis for determining the follow-up plan and adjuvant therapy after surgery.Methods The clinical data of 855 pa-tients with PitNETs were collected and reclassified according to the new WHO standard.The clinicopathological features of 13 patients diagnosed as MSPs were analyzed retrospectively.The immunohistochemical EnVision two-step method was used to de-tect the expression of PIT-1,SF-1,T-PIT,GH,PRL,TSH,LH,FSH,ACTH,etc.,and related literatures were reviewed.Methods A total of 855 cases of pituitary neuroendocrine tumor from the second hospital of the Chinese Hebei Medical U-niversity were collected and reclassified according to the new WHO standard,and review the literature.Results(1)The age of patients were 39-68 years with median age of 55 years.7 cases were female and 6 were male;(2)Imaging findings:There was 1.2～3.8 cm(mean 2.5 cm)in maximum tumor di-ameter.13 patients were large adenomas,neither MSPs nor sin-gle lineage PitNETs could not assessed on imaging;(3)Clinical manifestations:3 cases had hyperprolactinemia which all contai-ning PitNETs components of PRL,one case was immature PIT-1 polyhormone cell tumor,one was dense granular prolactinoma,and one case was eosinophilic stem tumor.One patient had Cushing's disease and contained a Crook cell tumor component;two had elevated ACTH,and one had an adrenocorticotropic ad-enomatous component.In the two patients with no evidence of hormone excess,all contained gonadotropin cell tumor compo-nents;(4)Combination form:11 cases of the combination of the two cell lineages(5 cases of combination of SF-1 lineage and PIT-1 lineage;4 cases of combination of T-PIT lineage and PIT-1 lineage;1 case of null cell tumor and PIT-1 lineage;1 case of plurihormonal PitNETs and SF-1 lineage);Two cases of three cell combinations(null cell tumor,PIT-1 lineage,and T-PIT lineage);Among them,13 cases were PIT-1 lineage tumors,46.2％(6/13)were gonadotropin cell tumor,38.5％(5/13)were prolactinoma;(5)The presence of high-risk lineage tumors in the 10 patient combinations:3 immature PIT-1-lineage tumor,1 Crooke cell PitNETs,1 acidophil stem cells tumor,3 zero-cell PitNETs,and 4 silent-type sparse granular adrenocorti-cotropic hormone PitNETs;Two of them were combinations of two high-risk subtypes.Conclusion MSPs in our center are large adenomas,although their incidence is only 1.5％of Pit-NETs,2/3 cases have high-risk lineage tumor components,and the use of pituitary cell lineage transcription factors and adeno-hypophyseal hormones plays an important role in distinguishing and clarifying the different components of MSPs.
