Patients with overlap syndrome(OS)of autoimmune liver disease may present with more than one biochemical,immunological,histological or cholangiography features of autoimmune liver disease(AILD)and often require a combination of immunosuppressants for treatment.Pulmonary cryptococcosis is a type of invasive pneumomycosis caused by Cryptococcus neoformans or Cryptococcus gattii and has a relatively high incidence rate in immunocompromised patients.This case report presents a patient with OS who was found to have pulmonary cryptococcosis during immunosuppressive therapy and developed abnormal liver function during antifungal treatment.Based on the liver function of the patient,the feasibility of adjusting antifungal agents was assessed,and active treatment strategies for novel cryptococcal infection were developed under the close monitoring of liver function,which helped to avoid the progression of infection.It is suggested that before the initiation of immunosuppressive therapy,systemic foci of infection should be comprehensively evaluated,and suspicious foci of infection should be monitored continuously.

Objective To evaluate the potential of miR-30a-5p as a novel indicator of acute myocardial infarction(AMI)and the underlying molecular mechanisms.Methods AMI-associated microRNAs(miRNAs)and mRNA microarray datasets were downloaded from the GEO database.Real-time fluorescence quantitative PCR(qRT-PCR)technique was used to detect the level of miRNAs in serum samples;automatic biochemistry was used to detect other biochemical indicators.Receiver operating characteristic(ROC)curve analysis and Spearson correlation analysis were performed to assess the value of miR-30a-5p as a diagnostic AMI marker.The target genes of miR-30a-5p were predicted with the R language multiMiR package,and the protein interaction network was constructed by the STRING database.The results were imported into Cytoscape 3.7.1 software to screen the pivotal genes of the network.The R language clusterProfiler package performed KEGG and GO analyses on the hub genes to explore the clinical significance of miR-30a-5p in AMI and its potential molecular mechanisms.Results Compared with the control group,miR-30a-5p was upregulated significantly in the serum of patients in the AMI group(P＜0.05);miR-30a-5p was positively correlated with the levels of CK-MB,CK,TnT,proBNP and CRP(rs=0.489,P＜0.001;rs=0.347,P＜0.001;rs=0.545,P＜0.001;rs=0.533,P＜0.001;rs=0.206,P＜0.05).The area under the ROC curve was 0.862,with sensitivity of 84.4％and specificity of 74.2％.A total of 780 differentially expressed genes(DEGs)were obtained from the two datasets.A total of 1 061 target genes of miR-30a-5p and 61 common genes were identified by taking the intersection set.Among the central genes of PPI,BCL6,FOSL2,JDP2,LYN,PDE4D,SOCS3 and SOX4 scored high and were closely associated with the occurrence of AMI.KEGG and GO enrichment analyses showed that miR-30a-5p might regulate JAK-STAT,NF-kappaB and Wnt signaling pathways,which were involved in inflammatory response,apoptosis,autophagy and post-infarction remodeling,and thus participated in the process of AMI.Conclusion Serum miR-30a-5p is up-regulated in the early stage of AMI,and the study on miR-30a-5p and its regulatory pathways can help with the diagnosis and treatment of myocardial infarction.

As a new hypoglycemic drug,Dapagliflozin has attracted much attention because of its unique hypoglycemic mechanism. It has been used in many studies on type 2 diabetes mellitus,but the application of type 1 diabetes mellitus(T1DM)in the eastern population is rare. This article uses Dapagliflozin through a case of obese T1DM to provide new ideas for the treatment of T1DM.

Objective:To investigate the efficacy of V-Y advancement flap with facial artery perforator for the repair of midface skin defects.Methods:A retrospective analysis was performed on 18 patients with facial skin cancer, including 11 males and 7 females, aged 65-83 years, who underwent the repair of midface skin defects using V-Y advancement flap with facial artery perforator in the Department of Head and Neck Surgery, Affiliated Cancer Hospital of Nantong University from January 2020 to April 2023. Medium, large or complex midface skin defects developed after surgical resections of the primary lesions. According to the defect site, size, location information of facial vessels, a V-Y advancement flap with appropriate shape was designed for each case. During the operation, the facial vessels and their perforators were retained in the pedicle of the flap, the facial nerve branches were dissected and protected, and the further denuded pedicle was determined according to actual amount of advancement. After the flap was advanced, the facial defect area was repaired without tension, and the anatomical positions and functions of the eyes, nose and mouth were restored as far as possible. Postoperative follow-ups were conducted to observe the survival rate of the flaps, postoperative complications, recurrences and metastases of tumors.Results:Midface defects of 3.0 cm×3.5 cm-6.5 cm×7.5 cm were observed after tumor resections, which involved one or more subregions. The sizes of the flaps were 3.5 cm×9.0 cm-7.0 cm×18.0 cm. All flaps were completely alive except for one with temporary local bruising. With following-up of 4-40 months, 5 of the 12 patients with lower eyelid and inner canthus invasions had lower eyelid ectropion, but no exposed keratitis was found; one case with poorly differentiated squamous cell carcinoma had lymph node metastasis in the submandibular region and underwent neck dissection again; no recurrence or metastasis occurred in the remaining cases.Conclusion:The V-Y advancement flap with facial artery perforator can be used to repair medium, large or complex midface skin defects, with a high survival rate, and the operation method is safe and reliable.

Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Objective:To investigate the clinical characteristics of cases with different congenital pulmonary airway malformations (CPAM) volume ratios (CVR) and the effect of maternal glucocorticoid treatment during pregnancy on CPAM.Methods:A retrospective study was conducted on 56 singleton pregnant women with fetal CPAM diagnosed prenatally in the Department of Obstetrics and Gynecology at Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, from September 2020 to May 2023. Among these, three cases received maternal glucocorticoid treatment during pregnancy and clinical conditions were reported in detail. Statistical analyses were performed using independent sample t-tests, non-parametric tests, Chi-square tests, or Fisher's exact test. Results:(1) General information: The average age of the 56 pregnant women with CPAM fetuses was (32.0±0.7) years. All fetuses had unilateral lesions, with 25 cases (44.6%) on the left side. Types Ⅰ, Ⅱ, and Ⅲ CPAM accounted for 5.4% (3/56), 50.0% (28/56), and 44.6% (25/56), respectively. Fetal hydrops occurred in two cases, and the maximum CVR during the fetal period for the other 54 non-hydropic fetuses was 0.79±0.66. (2) The CVR threshold for the risk of fetal hydrops was set as the mean maximum CVR of non-hydropic CPAM fetuses plus 2 standard deviations (0.79+2×0.66=2.1). The subjects were divided into two groups based on the maximum CVR during the fetal period: CVR≤2.0 group ( n=50) and CVR>2.0 group ( n=6). Comparison between the CVR>2.0 group and CVR≤2.0 group: The CVR>2.0 group had significantly higher rates of fetal hydrops [2/6 vs. 0.0% (0/50), Fisher's exact test], mediastinal shift [5/6 vs. 32.0% (16/50), χ 2=4.03], polyhydramnios [6/6 vs. 4.0% (2/50), Fisher's exact test], and postnatal surgery [4/5 vs. 22.2% (10/45), continuity correction χ 2=4.86] (all P<0.05). None of the fetuses with CVR≤2.0 had hydrops or received intrauterine intervention. The overall live birth rate was 89.3% (50/56). (3) Maternal glucocorticoid treatment during pregnancy: three of six fetuses with CVR>2.0 were treated with maternal glucocorticoid during pregnancy, and all were delivered alive at term after the intervention with resolution of edema and/or reduction in mass size. Two of them were treated with postnatal thoracoscopic surgery and were followed up to 5 and 14 months of age, respectively, with no abnormalities in feeding and development; the other was not treated surgically until 3 months of age, with no respiratory-related symptoms and no abnormalities in feeding and development. Conclusions:Prenatal ultrasound indicating CVR>2.0 is associated with increased rates of fetal hydrops, mediastinal shift, and polyhydramnios. Maternal glucocorticoid treatment during pregnancy may lead to favorable pregnancy outcomes for these CPAM fetuses.

Objective:To investigate the effectiveness and prognosis of using improved domestic neonatal ureteral stents (referred to as improved double-J stents) for thoraco-amniotic shunting (TAS) in treating fetal chylothorax.Methods:A retrospective analysis was conducted on the clinical data of 21 cases of fetal chylothorax treated with TAS using improved double-J stents at Nanjing Drum Tower Hospital, Nanjing University Medical School from April 1, 2018, to September 30, 2023. Surgical complications and perinatal outcomes were summarized, and the development of surviving infants in five domains (communication, gross motor, fine motor, problem-solving, and personal-social) was assessed using the Ages and Stages Questionnaires-Third Edition (ASQ-3). Descriptive statistical analysis was used. Results:(1) The median gestational age at prenatal diagnosis was 28.7 weeks (27.3-30.4 weeks), with 85.7% (18/21) of cases complicated by fetal hydrops, 90.5% (19/21) by polyhydramnios, and 85.7% (18/21) by bilateral pleural effusion. (2) The median gestational age at the first TAS was 30.9 weeks (29.7-32.7 weeks). Of the 21 cases, 10 required repeat stent placement due to dislodgement or blockage, with a total of 49 stent placements. The dislodgement rate within 7 days was 24.5% (12/49), and the blockage rate was 16.3% (8/49). The rate of premature rupture of membranes within one week post-stent placement was 9.5% (2/21), with an overall preterm premature rupture of membranes rate of 28.6% (6/21). The median interval from the first TAS to delivery was 30.0 d (19.8-40.0 d). Of the 21 cases, three opted for selective termination of pregnancy; the remaining 18 cases resulted in live births, with a median gestational age at delivery of 35.6 weeks (34.1-37.1 weeks), and three neonatal deaths. The overall neonatal survival rate was 15/18. Surviving infants were followed up to a median age of 30 months (7-48 months), with 13 showing normal development and two scoring below the ASQ-3 threshold.Conclusion:The improved double-J stent can be used for TAS in the treatment of fetal chylothorax, with generally favorable outcomes.

Objective:Construct a combined detection model of miR-202-5p and interleukin-6 (IL-6) and explore its diagnostic value for acute myocardial infarction (AMI).Methods:Clinical data of 202 patients with coronary atherosclerotic heart disease (CHD) who were admitted to the Department of Cardiology and Emergency Department of Hebei People's Hospital from August 2020 to August 2022 were retrospectively analyzed, including 106 AMI patients and 96 non AMI patients. The clinical characteristics and blood levels of miR-202-5p and IL-6 were compared between the two groups, T-test was used for inter group comparison of measurement data that conforms to normal distribution, non parametric rank sum test was used for inter group comparison of measurement data that does not conform to normal distribution, and χ2 test was used for inter group comparison of count data. Binary Logistic regression model was used to determine the independent influencing factors of AMI, and a combined diagnostic model was constructed according to the analysis results, the diagnostic efficacy of miR-202-5p, IL-6 and combined detection for AMI was evaluated by ROC curve, and the clinical diagnostic effect was observed. Results:The expression levels of serum total cholesterol (4.40 (3.71, 5.00) mmol/L), low density lipoprotein cholesterol (2.99 (2.39,3.47) mmol/L), lipoprotein a (276.80 (182.58,390.13) mg/L), interleukin-4(IL-4)(2.69(2.29,3.16) μg/L), IL-6(89.82(68.26,107.16) μg/L) in AMI group were significantly higher than those of non-AMI group (4.04 (3.12, 4.73) mmol/L, 2.75 (2.15, 3.21) mmol/L, 213.45 (146.73, 348.80) mg/L, 2.46 (1.92, 3.01)] μg/L, 45.89 (32.38, 62.83) μg/L, while miR-202-5p(0.33 (0.27,0.38)) was lower than that in the non-AMI group (0.51 (0.36,0.68)), ( H values were 4 167.50, 4 234.00, 4 262.50, 4 228.00, 1 513.00, and 2 098.50, respectively; P values were 0.027, 0.040, 0.047, 0.038, <0.001, <0.001, respectively). Multivariate binary logistic regression analysis showed that high levels of IL-6 and low levels of miR-202-5p were independent risk factors for AMI. The joint diagnostic model of IL-6 and miR-202-5p was Logit (P)=-1.046-5.236 × miR-202-5p+0.051 × IL-6, with probability value P as the diagnostic indicator and P=0.45 as the diagnostic threshold. ROC curve results showed that the area under curve (AUC) of IL-6 and miR-202-5p were 0.851 and 0.794, respectively, while the AUC of the combined diagnosis model was 0.894, indicating that the diagnosis accuracy was higher than that of a single index. Compared with isolated detection, the sensitivity, specificity and Kappa value of the IL-6+miR-202-5p collaborative test for AMI prediction were increased, especially the diagnosis results were close to a high degree of agreement with the actual results ( Kappa=0.732). Conclusion:High levels of IL-6 and low levels of miR-202-5p are independent influencing factors for AMI, and the combined diagnosis model of the two has clinical application value.

Objective:To investigate the feasibility of predicting the risk of spontaneous preterm birth in singleton pregnancy women with low risk of preterm birth by transabdominal-transvaginal ultrasound cervical length sequential screening in the second trimester.Methods:This prospective longitudinal cohort study included singleton pregnant women at 11-13 +6 gestational weeks who were admitted to Nanjing Drum Tower Hospital from January 2023 to September 2023. Transabdominal and transvaginal cervical lengths were measured during the mid-trimester fetal ultrasound scan at 18-24 weeks, and pregnancy outcomes were obtained after delivery. A short cervix was defined as a transvaginal cervical length of ≤25 mm, and the outcomes were defined as spontaneous preterm birth occurs between 20 and 36 +6 weeks and extremely preterm birth before 32 weeks. The area under the receiver operating characteristic (ROC) curve was used to evaluate the effectiveness of predicting spontaneous preterm birth by transabdominal and transvaginal cervix length, as well as the effectiveness of predicting short cervix by transabdominal cervical length. The relationship between transabdominal and transvaginal cervical length was evaluated using a scatter plot. Results:A total of 562 cases were included in this study, comprising 33 cases of spontaneous preterm birth (7 cases occurring before 32 weeks) and 529 cases of term birth. (1) Compared to the term birth group, transabdominal cervical length (median: 37.6 vs 33.2 mm; Z=-3.838, P<0.001) and transvaginal cervical length (median: 34.0 vs 29.9 mm, Z=-3.030, P=0.002) in the spontaneous preterm birth group were significantly shorter. (2) The areas under the ROC curve for predicting spontaneous preterm birth by transabdominal and transvaginal cervical length were 0.699 (95% CI: 0.588-0.809) and 0.657 (95% CI: 0.540-0.774), respectively. The sensitivity, specificity and positive predictive value of transvaginal cervical length Conclusions:In singleton pregnancy women with low risk of preterm birth, transabdominal-transvaginal cervical length sequential screening can reduce unnecessary transvaginal ultrasounds by approximately 41% without missing the diagnosis of pregnant women with a short cervix. This method also enhances the effectiveness of transvaginal cervical length to spontaneous preterm birth.

Objectives To investigate the regulatory role of miRNA-224-5p in hypoxia/reoxygenation(H/R)-induced H9c2 cardiomyocyte injury.Methods Plasma samples were collected from 160 patients with acute myocardial infarction and 80 healthy controls(HC)to measure miRNA-224-5p levels and other biochemical parameters.In cultured H9c2 cells with H/R injury,the effects of transfection with miR-224-5p mimics or a negative control sequence on cell viability,malondialdehyde(MDA)content,and superoxide dismutase 2(SOD2)and lactate dehydrogenase(LDH)activities were tested.Dual luciferase reporter gene assay was performed to verify the targeting relationship between miR-224-5p and PTEN.Bioinformatics methods were used to analyze the potential mechanisms of the target genes.The expression of miRNA-224-5p in the treated cells was detected with qRT-PCR,the protein expressions of PTEN,Bcl-2,Bax,cleaved caspase-3,SOD2,p-PI3K/PI3K,p-Akt/Ak and p-FoxO1/FoxO1 were determined using Western blotting,and cell apoptosis was analysed with flow cytometry.Results The levels of blood glucose,C-reactive protein,CK,CK-MB and cTnI were significantly higher in the AMI group compared with the HC group(P<0.05).The expression level of miR-224-5p was significantly lowered in patients with STEMI and NSTEMI and in H9c2 cells with H/R injury.The viability of H9c2 cells decreased time-dependently following H/R injury.PTEN was a target gene of miR-224-5p,and the PI3K/Akt pathway was the most significantly enriched pathway.H9c2 cells with H/R injury showed significantly decreased SOD2 activity,increased LDH activity and MDA content,increased cell apoptosis,decreased protein expression levels of p-PI3K,p-Akt,p-FoxO1,SOD2,and Bcl-2,and increased expressions of PTEN,Bax,and cleaved caspase-3.These changes were obviously attenuated by trasnfection of the cells with miR-224-5p mimics prior to H/R exposure.Conclusion MiR-224-5p overexpression upregulates the expression of the antioxidant gene SOD2 through the PI3K/Akt/FoxO1 axis to relieve H/R-induced oxidative stress and reduce apoptosis of H9c2 cells.
