Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Object·To explore the effects of comorbid obsessive-compulsive personality disorder(OCPD)on the behavioral inhibition system(BIS)/behavioral activation system(BAS)in patients with obsessive-compulsive disorder(OCD).Methods·A total of 247 patients with unmedicated OCD diagnosed in the Mental Health Center,Shanghai Jiao Tong University School of Medicine from 2014 to 2018 were included and divided into an OCD group(n=202),and an OCD+OCPD group(n=45),and 107 healthy controls were recruited as a comparison group.Yale-Brown Obsessive-Compulsion Scale(YBOCS),BIS/BAS Scale,Hamilton Depression Scale(HAMD),and Hamilton Anxiety Scale(HAMA)were used to assess psychopathological features.Gender differences among the three groups were analyzed using the x2 test.One-way analysis of variance(ANOVA)was used to compare differences in demographic characteristics,psychopathological features,and BIS/BAS scores,followed by the least significant difference(LSD)test for pairwise comparisons.Regression analysis was conducted to explore the relationships between psychopathological features and BIS/BAS scores.Results·There were no significant differences in gender,age,and years of education among the three groups.The scores of YBOCS(t=2.925,P=0.004),HAMD(t=2.130,P=0.034)and HAMA(t=2.568,P=0.011)in the OCD+OCPD group were significantly higher than those in the OCD group.There were statistically significant differences in BIS and BAS scores among the three groups(BIS:F=39.573,P＜0.001;BAS:F=3.915,P=0.021).The results showed that for BIS,there were statistically significant differences in pairwise comparisons among the three groups(OCD+OCPD vs OCD:P=0.002;OCD+OCPD vs HC:P＜0.001;OCD vs HC:P＜0.001),and the scores were OCD+OCPD＜OCD＜HC from low to high.For BAS,the OCD group scored significantly higher than the OCD+OCPD and HC groups(OCD+OCPD vs OCD:P=0.018;OCD vs HC:P=0.043),but there was no significant difference between the OCD+OCPD and HC groups.Regression models of BIS and BAS were constructed for OCD patients with OCPD,and the results showed that the overall prediction effect of the model was significant for BIS total scores(F=2.599,P=0.013).Only the severity of OCPD symptoms can significantly predict BIS scores(t=-2.282,P=0.023).For BAS total scores,the overall prediction effect of the model was not significant(F=1.438,P=0.191).Conclusion·Comorbid OCPD may be an adverse factor for abnormal BIS and a protective factor for abnormal BAS in patients with OCD.

Uveal melanoma (UM) poses a significant lethality, with approximately 50% of those developing metastases surviving less than one year. In the progression of UM, vasculogenic mimicry (VM) induced by hypoxia plays a pivotal role, which also partially explains the resistance of UM to anti-angiogenic therapies. Nevertheless, the crucial molecular mechanisms underlying VM in the progression of UM remain unclear. We identified ubiquitin conjugating enzyme E2 G2 (UBE2G2) as a critical suppressor through transcriptomic sequencing and metastasis correlation screening. In UM, hypoxia-induced VM and metastasis are markedly exacerbated by UBE2G2 knockdown and significantly alleviated by its overexpression. Mechanistically, UBE2G2 directly binds to galectin 3 binding protein (LGALS3BP) and forms a complex with the E3 ubiquitin ligase tripartite motif containing 38 (TRIM38), facilitating ubiquitination-mediated degradation of LGALS3BP at the K104 residue. Furthermore, UBE2G2 inhibits oncogenic phenotypes by inactivating intracellular PI3K/AKT signaling and reprogramming the tumor microenvironment. Therefore, targeting intercellular and intracellular molecular mechanisms of the hypoxia-UBE2G2-LGALS3BP axis may contribute to developing various therapeutic strategies for UM.

Objective:To further investigate the safety and efficacy of Belimumab in the treatment of patients with systemic lupus erythematosus (SLE).Methods:All SLE patients treated with Belimumab from May 1, 2020 to February 1, 2022 in Peking Union Medical College Hospital were retrospectively collected and analyzed. The clinical manifestations, the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2000) score, and laboratory test such as levels of anti-dsDNA antibody, the medication before and after Belimumab treatment, adverse events were collected. Normally distributed data were tested using the t-test, otherwise the Wilcoxon paired signed rank test was used. Results:A total of 81 patients were enrolled in this study. The use of belimumab could significantly decrease the SLEDAI-2000 score [10.00(7.75, 12.00) vs. 4.00(3.75, 6.00), Z=-5.38, P<0.001], ESR of SLE patients [19.50(12.75, 32.25) mm/1 h vs. 14.00(7.75, 20.25) mm/1 h, Z=-3.71, P=0.003], anti-dsDNA titer detected by CLIFT [300.00 (117.00, 864.00) vs. 183.00(100.00, 471.00), Z=-4.15, P=0.001], meanwhile, increase the complement C3 [0.78 (0.62, 0.97)g/L vs. 0.69 (0.55, 0.84)g/L, Z=-4.68, P<0.001], and the complement C4 [0.12 (0.08, 0.19)g/L vs. 0.10 (0.05, 0.14)g/L, Z=-4.78, P<0.001]. We also observed that with the use of Belimumab, the dosage of Glucocorticoids decreased significantly, which were [10.00(7.50, 22.50) mg vs. 7.50(5.00, 10.00) mg, Z=-4.90, P<0.001]. In addition, the antibody of IgG, IgA and IgM decreased significantly. Only one patient stopped the administration of Belimumab due to the low level of immunoglobulin. Conclusion:Belimumab can alleviate disease activity of patients with SLE and help in safely tapering the daily dose of glucocorticoid with good safety.

Background/Aims: Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Methods: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activitygroups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using surveylogistic regression and restricted cubic splines. Results: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Conclusions Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Objective:To compare the efficacy and safety of oral terbinafine versus itraconazole in the treatment of pediatric tinea capitis.Methods:From January 2021 to December 2021, a randomized clinical trial was conducted among 53 children with tinea capitis in Beijing Children′s Hospital. These patients were randomly divided into 2 groups by using a random number table: terbinafine group treated with oral terbinafine at different doses (weight <20 kg, dose: 62.5 mg/d; weight 20 - 40 kg, dose: 125 mg/d; weight >40 kg, dose: 250 mg/d), while itraconazole group treated with oral itraconazole at doses of 3 - 5 mg·kg -1·d -1. Statistical analysis was performed using the SPSS 23.0 software, and enumeration data were compared between groups by using chi-square test or Fisher′s exact test. Results:Totally, 27 patients were treated with oral terbinafine, including 17 with tinea alba and 10 with kerion; 26 were treated with oral itraconazole, including 17 with tinea alba and 9 with kerion. After treatment, 14 (51.85%) patients were cured in the terbinafine group, including 5 with tinea alba and 9 with kerion, while 25 (96.15%) were cured in the itraconazole group, including 16 with tinea alba and 9 with kerion. The response rate was significantly higher in the itraconazole group than in the terbinafine group ( χ2 = 13.37, P < 0.001) . Conclusion:The efficacy of itraconazole was superior to that of terbinafine in the treatment of pediatric tinea alba, but their efficacy was equivalent in the treatment of pediatric kerion.

Objective:To estimate the incidence and risk factors of acute kidney injury (AKI) in preterm infants, and provide basis for better evaluation and treatment of renal function in preterm infants.Methods:All the hospitalized premature infants who were admitted to three research centers (Department of Neonatology at Beijing Children′s Hospital; Department of Neonatology at Beijing Obstetrics and Gynecology Hospital; Department of Neonatology at Shunyi Maternal and Children′s Hospital of Beijing Children′s Hospital)from January 1, 2017 to June 30, 2019 and had more than two serum creatinine values or urine output were included.The incidence of AKI in preterm infants was calculated and the difference among different gestational weeks was compared.Preterm infants were divided into AKI and non-AKI groups according to AKI diagnostic criteria, and the clinical characteristics between two groups were compared, and the risk factors of AKI in preterm infants were analyzed.Results:A total of 763 premature infants were included in the analysis.Twenty two cases were diagnosed with AKI.The incidence of AKI in premature infants was 2.9%.The incidence of AKI was 33.3% (3/9), 3.7% (5/134), and 2.3% (14/620) in the 24-27 + 6 weeks, 28-31 + 6 weeks, and 32-36 + 6 weeks gestational age, respectively, and the difference was statistically significant ( χ2=31.010, P<0.001). Preterm infants in AKI group had a higher proportion of males(77.3% vs. 53.3%), lower gestational weeks[29(27, 33) weeks vs.31(29, 33)weeks], higher proportions of infants with diabetic mothers(40.9% vs.19.4%), lower Apgar scores at 1 and 5 minutes[8(7, 10) vs.9(8, 10), 9(9, 10) vs.10(9, 10), respectively], higher proportions of invasive and noninvasive respiratory support(45.5% vs.11.3%, 63.6% vs.19.2%, respectively), longer duration of invasive respiratory support[260(136, 742)h vs.72(18, 160)h], longer hospital stays[66(19, 88)d vs.42(26, 58)d], and higher rates of sepsis (27.3% vs. 6.5%), respiratory distress syndrome(40.9% vs. 11.6%), and patent ductus arteriosus that requiring ibuprofen or surgical closure(13.6% vs. 3.0%), diuretic(27.3% vs. 3.9%), and vasoactive drug use (22.7% vs. 3.6%) than those in non-AKI group, and the differences were statistically significant(all P<0.05). Multivariate regression analysis showed that sepsis was an independent risk factor for AKI in preterm infants ( P=0.039, OR=3.498, 95% CI 1.065-11.490) after adjustment of gestational age and birth weight. Conclusion:The incidence of AKI is relatively high in preterm infants with gestational age<28 weeks.Compared with preterm infants without AKI, preterm infants with AKI have smaller gestational weeks and longer hospital stay.Sepsis is an independent risk factor for AKI in preterm infants.

OBJECTIVE：To investigate the effects of dexmedetomidine on regional cerebral oxygen saturation and cerebral function in patients undergoing intracranial aneurysm embolization. METHODS ：Totally 44 patients undergoing intracranial aneurysm embolization in the First Affiliated Hospital of Hunan University of TCM during Jun. 2017-Aug. 2019 were collected and randomly divided into group D （22 cases）and group C （22 cases）. Ten minutes before anesthesia induction ，group D was given intravenous injection of Dexmedetomidine hydrochloride injection 1 μg/kg；group C was given buffered normal saline 20 μL. Both groups were induced with Propofol emulsion injection+Midazolam injection+Fentanyl citrate injection+Cisatracurium besylate for injection. During the operation ，group D was given Dexmedetomidine hydrochloride injection 0.5 μg（/ kg·h）+Fentanyl citrate injection+Benzsulfosum atracurium for injection+Propofol emulsion injection to maintain anesthesia ；group C was continuously pumped with buffered normal saline 0.5 μg（/ kg·h）+Fentanyl citrate injection + Benzsulfosum aratracurium for injection Propofol emulsion injection to maintain anesthesia. Before anesthesia induction （T0）， immediately after anesthesia。induction （T1）， 1 min after tracheal intubation （T2）， immediately after operation finished （T3），immediately afte extubation（T4），the mean arterial pressure（MAP），heart rate 中国药房 2021年第32卷第7期 China Pharmacy 2021Vol. 32 No. 7 ·865· （HR），regional cerebral oxygen satur ation（rSO2）were observed in 2 groups. The levels of neuron specific enolase （NSE）and S100 β protein in serum were measured at T1，T3，6 h after operation （T6）. The recovery time ，intraoperative blood loss ， nitroglycerin amount and the occurrence of ADR were recorded. RESULTS ：MAP and HR of group D at T 2-T4 were significantly lower than those at T 0；MAP and HR of group C at T 2-T4 were significantly higher than those at T 0；the group D were significantly lower than the group C at the same period （P＜0.05）；there was no statistical significance in rSO 2 between 2 groups at T 0-T4（P＞ 0.05）. The levels of serum NSE and S 100β protein in 2 groups at T 3 were significantly higher than at T 1；those in 2 groups at T 6 were significantly lower than at T 3，but those of group D were significantly lower than the group C at T 3（P＜0.05）；there was no statistical significance in the levels of serum NSE or S 100β protein between 2 groups at T 1（P＞0.05）. The recovery time of anesthesia，the amount of nitroglycerin ，the incidence of tachycardia ，nausea and vomiting ，restlessness，shivering and cough in group D were significantly shorter or lower than group C （P＜0.05）；there was no statistical significance in the intraoperative blood loss between 2 groups（P＞0.05）. CONCLUSIONS ：Dexmedetomidine can maintain the hemodynamic stability of patients with intracranial aneurysm embolization during the perioperative period ，has little effect on rSO 2 and brain function ，and has good safety.
