Objective To explore the relationship between hepatocyte nuclear factor 1A(HNF1A)-associated congenital hyperinsulinism(CHI),HNF1A-maturity-onset diabetes of the young(MODY)and C-reactive protein(C-RP)levels.Methods PubMed,CNKI and Wanfang Data were searched for literature on HNF1A gene mutation published from inception to December 2023,and the genetic and clinical information of HNF1A mutation-related CHI and HNF1A-MODY were extracted.According to the clinical phenotypes,the HNF1A mutation sites included in the literature were divided into the Biphenotypic mutations(Biphenotypic,n=84)group and the DM phenotype-associated mutations(DM,n=378)group.The levels of C-RP and C-P were collected and compared in patients with HNF1A-MODY and T2DM by meta-analysis.Results A total of 9 articles about HNF1A mutation-related CHI were included,and 19 mutation sites were found to be associated with CHI.A total of 143 articles related to HNF1A-MODY were included,and 589 mutation sites were found to be associated with HNF1A-MODY.The age at diagnosis and 2 hPG were significantly lower in the Biphenotypic group than in the DM group(P<0.05).A total of 11 articles were included in the meta-analysis.Compared with T2DM patients,HNF1A-MODY patients had lower C-RP(MD-1.61,95%CI-1.96～-1.26,P<0.05)and lower C-P(MD-0.95,95%CI-1.87～-0.03,P<0.05).Conclusions CHI is an important clinical feature of HNF1A-MODY,and hyperinsulinemia may exist before the decline of islet β cell function.

Aim To investigate whether protein inhibitor of activated STAT3(PIAS3)deficiency exacerbates the occurrence and development of atherosclerosis(As)in female ApoE knockout mice.Methods PIAS3 gene knockout mice with ApoE-/-background(PIAS3-/-/ApoE-/-)and their littermate PIAS3+/+/ApoE-/-mice were bred and fed with a high-fat/high-cholesterol diet for 12 weeks to induce As.Body weight(every week)and plasma lipid levels including to-tal cholesterol,triglyceride,high density lipoprotein cholesterol and non-high density lipoprotein cholesterol(every 4 weeks)of the mice were measured.Oil red O staining,HE staining,immunohistochemistry staining and immunofluores-cence staining were performed on mouse aortic tree and frozen sections of aortic root to evaluate the area,cellular composi-tion and stability of As plaques.Moreover,the expression of estrogen receptor α(ERα)and its co-localization with vas-cular smooth muscle cells(VSMC)in plaques were determined by immunofluorescence staining.Results Compared with PIAS3+/+/ApoE-/-mice,PIAS3-/-/ApoE-/-mice showed no significant differences in body weight,major organ weight(heart,liver,spleen,kidney and epididymal fat)and plasma lipid levels;however,PIAS3 deficiency promoted the forma-tion of As in female PIAS3-/-/ApoE-/-mice.Compared with PIAS3+/+/ApoE-/-mice,PIAS3-/-/ApoE-/-mice showed an increased lipid accumulation and a decreased VSMC content in As plaques(P＜0.05),leading to a decrease in plaque stability.In addition,the expression of ERα in the As plaques of PIAS3-/-/ApoE-/-mice was significantly downregulated(P＜0.05),and there was a obvious co-localization between ERα and VSMC.The reduction of VSMC content in PIAS3-/-/ApoE-/-mouse plaques might lead to a decrease of ERα expression,thereby weakening the anti-As effect of es-trogen.Conclusion PIAS3 deficiency exacerbates the formation of As plaques in female PIAS3-/-/ApoE-/-mice,which might be due to the regulatory effect of PIAS3 on ERα expression in plaques.

Background and purpose:Lung adenocarcinoma has the characteristics of difficult early detection,rapid tumor progression and low surgical resection rate.Although studies on immunotherapy alone and immunotherapy combined with chemotherapy have shown initial success in improving prognosis and overcoming drug resistance,the majority of lung adenocarcinoma patients still receive limited benefits.Therefore,there is an urgent need to identify novel biomarkers with relatively high sensitivity and specificity to improve the prognosis of lung adenocarcinoma.Cell division cycle protein 20(CDC20)is involved in the occurrence and development of various tumors,but its biological role and mechanism in lung adenocarcinoma remain unclear.The aim of this study was to investigate the expression of CDC20 in lung adenocarcinoma and its predictive value for the prognosis of patients with lung adenocarcinoma,and to further explore the effects of CDC20 on the proliferation and invasion capabilities of lung adenocarcinoma cells.Methods:Utilizing immunohistochemistry(IHC)to detect the expression of CDC20 in lung adenocarcinoma tissues,we analyzed its correlation with poor prognosis in combination with bioinformatics and clinicopathological parameters.Kaplan-Meier survival curves were employed to illustrate the impact of CDC20 on postoperative survival rates in lung adenocarcinoma patients.COX multivariate regression analysis was conducted to identify independent prognostic factors influencing postoperative survival rates.Additionally,receiver operating characteristic(ROC)curves were applied to assess the diagnostic value of CDC20 expression in lung adenocarcinoma patients.Real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR)and Western blot were used to measure the expression levels of CDC20 in normal human lung epithelial cells(BEAS-2B)and human lung adenocarcinoma cells(A549 and H1299).In cellular experiments,CDC20 was knocked down in lung adenocarcinoma cells,which were divided into three groups:si-NC(control group),si-CDC20#1(knockdown group 1)and si-CDC20#2(knockdown group 2).Cell counting kit-8(CCK-8),colony formation,transwell and wound healing assays were conducted to assess cell proliferation,migration and invasion capabilities.Functional enrichment analysis using Geng Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways was conducted to explore the biological roles of CDC20 in lung adenocarcinoma.Finally,gene set enrichment analysis(GSEA)was employed to investigate potential regulatory pathways of CDC20 in lung adenocarcinoma.This study was approved by the Ethics Committee of Hebei Chest Hospital(Number:2022051).Results:The results of both bioinformatics analysis and IHC demonstrated a significantly high expression of CDC20 in lung adenocarcinoma tissues(P＜0.05).Both bioinformatics analysis and clinical parameter evaluation revealed a correlation between high CDC20 expression and poor patient prognosis.Kaplan-Meier survival analysis and COX regression analysis consistently indicated a significant negative correlation between CDC20 expression and postoperative survival rates in patients(P＜0.05).Additionally,the expression levels of CDC20 were higher in human lung adenocarcinoma cell lines A549 and H1299 compared with BEAS-2B(P＜0.05).Knockdown of CDC20 effectively inhibited the proliferation,migration and invasion of lung adenocarcinoma cells(P＜0.05).The results of GO,KEGG pathways and GSEA consistently pointed to a relationship between CDC20 and cell cycle regulation.Conclusion:CDC20 is highly expressed in lung adenocarcinoma.High expression of CDC20 is an independent risk factor for poor prognosis of lung adenocarcinoma patient.CDC20 can promote the proliferation,migration and invasion of lung adenocarcinoma cells.

AIM:To explore the molecular mecha-nism of Fuyangjing gel in the treatment of chronic eczema rats model based on janus protein kinase 1(JAK1)/signal transducer and activator of transcrip-tion 5(STAT5)signaling pathway.METHODS:Thirty-six SPF Wistar rats were randomly divided into nor-mal group,model group,Qingpeng ointment group,Fuyangjing gel low,medium and high dose groups.Except the normal group,the other groups of rats were treated with 2,4-dinitrochlorophenone solution to induce chronic eczema-like lesions on the back.After 3 weeks of modeling,Qingpeng ointment group and Fuyangjing gel low,medium and high dose groups were respectively treated with corresponding drugs.The model group was smeared with blank gel matrix once a day for 2 weeks,while the normal group was not treated.The severity and pathological changes of back le-sions in chronic eczema rats were observed.The ex-pression of phosphorylated protein tyrosine kinase 1(p-JAK1)and phosphorylated signal transduction and transcriptional activator 5(p-STAT5)in rat dor-sal skin was detected by Western blot.Detection of thymic stromallymphopietin(TSLP),JAK1,STAT5,in-terleukin-10(IL-10)and IL-17 mRNA expression lev-els in rat back skin by qRT-PCR;The levels of IL-4,IL-6,IL-10,IL-13 and IL-17 in serum of rats were deter-mined by enzyme-linked immunosorbent assay(ELI-SA).RESULTS:Compared with normal group,the se-rum levels of IL-4,IL-6,IL-13 and IL-17 in model group were significantly increased,while IL-10 lev-els were significantly decreased(P＜0.05).The ex-pression levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were significantly increased,while IL-10 mRNA levels were significantly decreased(P＜0.05).Compared with model group,serum levels of IL-4,IL-6,IL-13 and IL-17 in Qingpeng ointment group and Fuy-angjing gel low,medium and high dose groups were significantly decreased,while IL-10 levels were significantly increased(P＜0.05).The expres-sion levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were significantly decreased,while the mRNA levels of IL-10 were significantly increased(P＜0.05).The serum levels of IL-4,IL-6,IL-13 and IL-17 in Qingpeng oint-ment group were decreased,while IL-10 levels were increased(P＜0.05).The expression levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were decreased,while the mRNA levels of IL-10 were increased(P＜0.05).Com-pared with Qingpeng ointment group,there were no significant differences in serum levels of IL-4,IL-6,IL-10,IL-13 and IL-17 in Fuyangjing gel high-dose group(P＞0.05).There were no significant differenc-es in the expression levels of p-JAK1,p-STAT5 pro-tein and TSLP,JAK1,STAT5,IL-10 and IL-17 mRNA in back lesions(P＞0.05).CONCLUSION:Fuyangjing gel may play a role in the treatment of chronic eczema by regulating the expression of JAK1/STAT5 signal-ing pathway related inflammatory factors,proteins and genes.

Objective To explore the predictive efficacy of platelet distribution width/platelet count(PDW/PLT)in retinopathy in patients with type 2 diabetes mellitus(T2DM).Methods A total of 120 pa-tients with T2DM admitted to Ma'anshan 17th Metallurgical Hospital from January 2020 to January 2023 were selected as the study group and were divided into the non-retinopathy group(n=69)and the retinopathy group(n=51).Another 80 healthy people who came to the hospital for physical examination during the same period were selected as the control group.The PDW and PLT were detected in all subjects after admission,and the PDW/PLT was calculated.The general data and biochemical indexes of each group were analyzed and compared.Receiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of PDW/PLT in patients with T2DM complicated with retinopathy,and multivariate Logistic regression was used to analyze the related factors affecting patients with T2DM complicated with retinopathy.Results PDW and PDW/PLT in the study group were higher than those in the control group,and PLT was lower than that in the control group,and the differences were statistically significant(P＜0.05).PDW and PDW/PLT in the ret-inopathy group were higher than those in the non-retinopathy group,and PLT was lower than that in the non-retinopathy group,and the differences were statistically significant(P＜0.05).The ROC curve analysis re-sults showed that the area under the curve(AUC)of PDW for predicting retinopathy in T2DM patients was 0.840(95％CI:0.790-0.890),and the AUC of PLT for predicting retinopathy in T2DM patients was 0.765(95％CI:0.715-0.815),and the AUC of PDW/PLT for predicting retinopathy in T2DM patients was 0.906(95％CI:0.876-0.936).Multivariate Logistic stepwise regression analysis results showed that disease dura-tion(OR=3.047,95％CI:1.863-4.983),glycosylated hemoglobin(OR=3.963,95％CI:1.976-7.947),PDW/PLT(OR=4.191,95％CI:1.833-9.584)were risk factors for retinopathy in patients with T2DM(P＜0.05).Conclusion PDW/PLT is increased in T2DM patients with retinopathy,which could be used as an inde-pendent risk factor for T2DM patients with retinopathy,and has a high predictive value for retinopathy.

Objective:To compare the diagnostic efficacy of 68Ga-PSMA-11 PET/ CT and multi-parameter magnetic resonance imaging (mpMRI) for pelvic lymph node metastases in prostate cancer patients who received neoadjuvant endocrinology or not after initial diagnosis. Methods:Data of 52 patients with moderate and high-risk prostate cancer admitted to Xijing Hospital from February to October 2023, aged (65.8±6.6) years, preoperative prostate-specific antigen (PSA) 26.67 (13.09, 84.89) ng/ml, were retrospectively analyzed. Before operation, there were 28 cases of cT 2stage, 16 cases of cT 3 stage and 8 cases of cT 4 stage. There were 22 cases of cN 0 and 30 cases of cN 1. All patients underwent 68Ga-PSMA-11 PET/CT and mpMRI at the same time, and were diagnosed positive lymph nodes in 28 and 21 cases, respectively. Risk stratification were high risk in 45 cases, and medium risk in 7 cases. According to the preoperative endocrine treatment, they were divided into the newly diagnosed group without treatment (24 cases) and the endocrine treated group (28 cases), whose ages were (65.0±7.1) years and (66.8±6.1) years, respectively. Preoperative PSA was 26.17 (16.73, 61.18) ng/ml and 27.32 (11.94, 130.18) ng/ml, respectively. Gleason scores ≤7 were in 10 cases (41.7%) and 6 cases (21.4%), and Gleason scores >7 were in 14 cases (58.3%) and 22 cases (78.6%), respectively. There were 15 (62.5%) and 13 (46.4%) cases of cT 1-2 stage, and 9 (37.5%) and 15 (53.6%) cases of cT 3-4 stage, respectively. There were 16 (66.7%) and 6 (21.4%) cases of stage N 0, 8 (33.3%) and 22 (78.6%) cases of stage N 1, respectively. There were 22 (91.7%) and 20 (71.4%) cases of stage M 0, 2 (8.3%) and 8 (28.6%) cases of stage M 1, respectively. PET/CT diagnosis of lymph node positive was in 9 cases (37.5%) and 19 cases (67.9%), and mpMRI diagnosis of lymph node positive was in 5 cases (20.8%) and 16 cases (57.1%). The number of positive lymph nodes diagnosed by PET/CT was 13 (72.2%) and 47 (90.1%), and the number of positive lymph nodes diagnosed by mpMRI was 8 (44.4%) and 32 (61.5%). There was no significant difference ( P>0.05). All patients underwent radical prostatectomy as well as enlarged pelvic lymph node resection. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the two imaging examinations in the diagnosis of lymph node metastasis were compared according to the results of postoperative pathological examination of lymph nodes. Receiver operating characteristic (ROC) curve was used to compare the accuracy of the two imaging tests in the diagnosis of pelvic lymph node metastasis in the newly diagnosed untreated group and the endocrine treated group. Results:In this study, of 52 cases, 26 (50.0%) had positive lymph nodes by pathological examination. In this study, a total of 681 lymph nodes were dissected, with 70 lymph nodes (10.28%) being pathologically positive, and the positive rate of 26 patients was 17.99% (70/389). The PET/CT and mpMRI detection rates of 26 node-positive patients were 92.3% (24/26) and 57.7% (15/26), respectively. There were 9 (37.5%) and 17 (60.7%) lymph node positive patients in the untreated group and the endocrine therapy group, respectively. There were 320 and 361 lymph nodes were clear, with 18 (5.6%) and 52 (14.4%) positive lymph nodes, respectively. The detection rates of PET/CT and mpMRI were 88.89% (8/9) and 94.12% (16/17)in the untreated group, and 44.44% (4/9) and 64.71% (11/17)in the endocrine treated group, respectively. In the newly treated group, the area under the curve (AUC) of PET/CT and mpMRI for diagnosing positive lymph nodes were 0.911 and 0.689 ( P=0.027), the sensitivity were 88.9% and 44.4%, and the specificity were 93.3% and 93.3%, respectively. PPV were 88.9% and 80.0%, and NPV were 93.3% and 73.7%, respectively. In the endocrine therapy group, the AUC of PET/CT and mpMRI for lymph node positive diagnosis were 0.834 and 0.596 ( P=0.011), the sensitivity were 94.1% and 64.7%, the specificity were 72.7% and 54.5%, and the PPV were 84.2% and 68.8%, respectively. NPV were 88.9% and 50.0%, respectively. Conclusions:For prostate cancer patients, regardless of whether they receive neoadjuvant endocrine therapy, 68Ga-PSMA-11 PET/CT can accurately detect pelvic lymph node metastasis, and the diagnostic efficacy is significantly better than that of mpMRI.

Objective:To investigate the risk factors for biochemical recurrence after radical prostatectomy.Methods:The clinical data of 558 radical prostatectomy patients admitted to the First Affiliated Hospital of Air Force Military Medical University from January 2010 to December 2020 were retrospectively analyzed. The average age was 67.9 (40-87) years old, and the average body mass index was 24.56 (15.12-35.94) kg/m 2. The average PSA was 41.07 ng/ml, including 48 cases<10 ng/ml, 98 cases 10-20 ng/ml, and 412 cases>20 ng/ml. There were 123, 214, 118, 89, and 14 cases with biopsy Gleason 6-10 score, respectively. The clinical stage : 90 cases in ≤T 2b, 273 cases in T 2c, and 195 cases in ≥T 3 . 558 cases underwent radical prostatectomy, including 528 robotic-assisted laparoscopic surgery, 25 laparoscopic surgery, and 5 open-surgery. The risk factors for postoperative biochemical recurrence were analyzed by Cox regression. Results:A total of 63 patients had postoperative pathological stage pT 2a, 32 patients had pT 2b, 241 patients had pT 2c, and 222 patients had ≥pT 3. A total of 210 cases developed biochemical recurrence after surgery, and the mean time to biochemical recurrence was 33.3 (3-127) months after the radical prostatectomy. The biochemical recurrence rates at 1, 3, and 5 years were 9.7% (54/558), 21.5% (120/558), and 31.7% (177/558), respectively. Among pT 2a and pT 2b patients, 7 (11.1%) and 4 (12.5%) cases developed biochemical recurrence, respectively. Among pT 2c stage patients, 145 (60.17%) cases had positive cut margins, treated with androgen-deprivation therapy (ADT) after surgery. 68 (28.21%) cases of pT 2c stage patients had biochemical recurrence at mean 36.1 (3-106)months after the radical prostatectomy. Among ≥pT 3 patients, 147 patients with positive margins, perineural invasion, seminal vesicle invasion and positive pelvic lymph nodes were treated with postoperative androgen deprivation therapy (ADT) + radiotherapy. 98 of 147 patients (66.67%) had biochemical recurrence, and the average time to biochemical recurrence was 30.6 (24-98) months.75 patients of ≥pT 3 without positive margins, perineural invasion, seminal vesicle invasion or positive pelvic lymph nodes, were treated with postoperative ADT. 33 of them (44%) had biochemical recurrence, and the average time to biochemical recurrence was 32.5 (21-106) months. 5-and 10-year survival rates of 210 patients with biochemical recurrence were 89.05% (187/210) and 78.09% (164/210) respectively, 5- and 10-year tumor-specific survival rates were 92.57% and 87.69%, respectively. 46 of 210 cases died, of which 31 (67.39%) died from prostate cancer, and 15 cases (32.61%) died from cardiovascular and cerebrovascular diseases. Multifactorial Cox regression analysis showed that patient's age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7 were independent risk factors for biochemical recurrence. Conclusions:After radical prostatectomy, patients were treated according to their pathological stage and surgical margins. Patients with positive margins have a higher risk of biochemical recurrence. The independent risk factors for biochemical recurrence included age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.
