Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Objective: To investigate the association between habitual reading/writing postures and the co-occurrence of common health conditions (overweight/obesity, visual impairment, hypertension, and scoliosis) and comorbidities among children and adolescents, in order to provide data support for the joint prevention of common diseases and comorbidities among children and adolescents. Methods: From September 2021 to June 2022, a multi-stage cluster random sampling method was used to select a total of 4 577 children and adolescents from 16 primary and secondary schools in Ningxia: Jinfeng District of Yinchuan City, Shapotou District of Zhongwei City, Yanchi County of Wuzhong City, and Pingluo County of Shizuishan City. A weighted complex sampling design was used to investigate the association of habitual reading and writing postures with common comorbidities in children and adolescents. Results: The prevalence rates of common diseases among children and adolescents in Ningxia were as follows: overweight/obesity was 22.87%, visual impairment was 62.52%, scoliosis was 2.30%, and hypertension was 1.30%. The prevalence of multimorbidity (co-occurrence of ≥2 conditions) among Ningxia children and adolescents was 15.95%. Multivariate unconditional Logistic regression analysis showed that frequent/always collapsing waist and sitting forward with head lowered increased the risk of common comorbidities in children and adolescents ( OR =1.90, P <0.05). Compared with the corresponding reference group, male children and adolescents aged 9 to 12 years and boys had relatively lower risks of overweight/obesity ( OR =0.71, 0.70); the risk of poor vision among children and adolescents aged 9 to 12 years, male, and urban was relatively low ( OR =0.59, 0.60, 0.73)( P < 0.05 ). Children and adolescents who often/always sat leaning to the left or right were at higher risk of poor vision ( OR =1.78); urban children and adolescents had a higher risk of developing scoliosis ( OR =3.71); children and adolescents aged 9 to 12 had a relatively low risk of developing hypertension ( OR =0.09), and children and adolescents who often/always bent their backs and sat forward on their knees had a higher risk of hypertension ( OR =5.03)( P <0.05). Conclusions Ningxia has a high incidence of common diseases and multiple diseases among children and adolescents, frequent or always collapsing waist and sitting forward with head lowered is associated with common comorbidities in children and adolescents in Ningxia. Proper postural measures for reading and writing should be carried out as soon as possible to encourage children and adolescents to develop good reading and writing habits for effectively preventing and controlling the occurrence of common diseases.

OBJECTIVE: To investigate the expression levels of EZH2 and KMT2D in patients with diffuse large B-cell lymphoma (DLBCL) and their relationship with pathological features. METHODS: 84 patients with DLBCL treated in our hospital from January 2021 to June 2022 were selected as the study subjects, and clinical characteristics such as sex, age and pathological classification of the patients were collected. Immunohistochemistry was used to detecet the expression of KMT2D and EZH2 proteins in tumor tissue cells of the DLBCL patients. The differential expression of KMT2D and EZH2 in subgroups of different sexes, ages, primary sites, clinical stages, Hans subtypes, etc. were compared. The correlation between the expression of KMT2D and EZH2 protein and BCL-6, CD79A was analyzed and validated through the interaction of protein molecular structures. We followed up and recorded the survival status of the patients for 12 months, and analyzed the factors that affect the mortality of DLBCL patients. RESULTS: The positive rate of KMT2D and EZH2 was high (over 95%) in DLBCL patients. There was no significant difference in the expression of EZH2 and KMT2D among subgroups of different sexes, ages and stages (P >0.05). However, patients with different levels of BCL-6 and CD79A expression showed differences in EZH2 and KMT2D expression (P < 0.05). EZH2 and KMT2D were positively correlated with BCL-6 (r =0.391, r =0.332) and CD79A (r =0.309, r =0.258), respectively, and there were interactions in the protein molecular structures. The risk factors for mortality in DLBCL patients include male sex (OR =1.106, 95%CI : 1.082-1.130, P < 0.001), stage II (OR =1.778, 95%CI : 1.567-2.016, P < 0.001), stage IV (OR =2.233, 95%CI : 2.021-2.467, P < 0.001), EZH2 positive (OR =2.762, 95%CI : 1.304-5.850, P =0.008), BCL-6 positive (OR =7.309, 95%CI : 1.340-39.859, P =0.022), age≥74 years (OR =3.080, 95%CI : 1.658-5.723, P < 0.001), and 63-73 years old (OR =2.400, 95%CI : 1.564-3.682, P < 0.001), while KMT2D positive (OR =0.180, 95%CI : 0.054-0.608, P =0.006) and 41-51 years old (OR =0.406, 95%CI : 0.274-0.603, P < 0.001) were factors which could reduce the risk of mortality. CONCLUSION EZH2 and KMT2D are highly expressed in patients with DLBCL, and they are positively correlated with BCL-6 and CD79A, and affect the prognosis of DLBCL patients.

Lingguizhugan Decoction (LGZG) demonstrates significant efficacy in treating various cardiovascular diseases clinically, yet its precise mechanism of action remains elusive. This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol (ISO) continuous stimulation-induced chronic heart failure (CHF) in mice, providing direct experimental evidence for further clinical applications. In vivo, continuous ISO infusion was administered to mice, and ventricular myocytes were utilized to explore LGZG?s potential mechanism of action on the ?1-adrenergic receptor (?1-AR)/Gs/G protein-coupled receptor kinases (GRKs)/?-arrestin signaling deflection system in the heart. The findings reveal that LGZG significantly reduced the messenger ribonucleic acid (mRNA) expression of hypertrophy-related biomarkers [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF. Furthermore, LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling and downregulated the downstream transcriptional activity of cAMP-response element binding protein (CREB) and the expression of the coactivator CBP/P300. Notably, LGZG downregulated the expression of ?-arrestin1 and GRK 2/3/5 while upregulating the expression of ?1-AR and ?-arrestin2. These results suggest that LGZG inhibits Gs/cAMP/PKA signaling and ?-arrestin/GRK-mediated desensitization and internalization of ?1-AR, potentially exerting cardioprotective effects through the synergistic regulation of the ?1-AR/Gs/GRKs/?-arrestin signaling deflection system via multiple pathways.

Objective: To investigate the clinical efficacy of en bloc resection of ureteral orifice in the treatment of tumors around ureteral orifice. Methods: Clinical data of 43 patients treated at our hospital during Jul.2018 and Jun.2023 were retrospectively analyzed，including 34 male and 9 female patients.Prior to surgical intervention，all patients were diagnosed with bladder masses via imaging or cystoscopy，and no concurrent upper urinary tract tumors were detected.The initial surgical procedure was transurethral resection of bladder tumor，which removed the tumors around ureteral orifice.Subsequently，electrocoagulation was employed for hemostasis，followed by the placement of a double-J tube into the affected ureter.Tumor recurrence and hydronephrosis were observed after operation. Results: All operations were successful without conversion to open surgery.The operation time was (61±25) min.The postoperative pathological results showed 28 cases of Ta stage tumors，14 cases of T1 stage tumors，and 1 case of T2 stage tumor.During the follow-up of (17±11) months，8 patients (19%) had tumor recurrence，among whom 4 (9%) had recurrent tumor involving the ureteral orifice，and 1 (2%) had transient hydronephrosis after removal of double-J tube. Conclusion: The en bloc resection of the ureteral orifice with placement of a double-J tube is safe and effective for the treatment of tumors around the ureteral orifice，with low recurrence rate.It is an optional procedure for early stage patients.

Objective:To design an auxiliary device based on embedded microcontroller system for venipuncture,which can adjust posture,so as to resolve the problem that occurs failure in puncture due to insufficient exposure of the puncture site in various scenarios.Methods:The device consisted of a support component,an air ring,a component with lifting and angle adjustment,and a pedestal.By advanced embedded microcontroller technique,it can precisely regulate the posture of the support structure of patient's limbs,and fully expose the targeted puncture site,and create more favorable conditions for nurses in performing punctures.A total of 2,482 patients who underwent blood collection at emergency department of the 305th Hospital of the People's Liberation Army from September to October 2024 were selected.The 1,204 patients were enrolled in September were divided into control group(without using the auxiliary device for venipuncture),and the 1,278 patients were enrolled in October were divided into observation group(using the auxiliary device for venipuncture).The puncture's one-time success rates of junior nurses(experience≤3 years)for both groups were compared.Each group respectively selected 150 patients by using the random number table method to conduct investigate,and satisfaction scores for success rate of puncture,and comfort degree of puncture for position,as well as the pain,process and efficiency,were investigated Results:The puncture's one-time success rates of junior nurses for the patients of control and observation groups were respectively 85.05%and 89.36%,with a statistically significant difference(x2=10.35,P<0.05).The satisfaction scores of patients in the observation group were significantly higher than those in the control group,with a statistically significant difference(t=-5.529,P<0.05).Conclusion:This device is simple and convenient in operation,and has favorable stability.It is beneficial to adjust position and exposure puncture site for patients who undergo peripheral venipuncture.It can improve puncture's success rate and patients'satisfaction.

Objective:To investigate the prevalence status and the clinical characteristics of hepatitis D virus (HDV) among patients chronically infected with hepatitis B virus (HBV) in the Xinjiang region.Methods:A cross-sectional study was conducted. Serum samples from 1 830 patients with chronic HBV infection who visited the Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from December 2022 to October 2023 were collected. All sera were tested for anti-HDV IgG and IgM. Sera positive for anti-HDV IgG or IgM were selected for HDV RNA detection. HDV RNA-positive sera were sequenced to determine the HDV genotype. Age, gender, HBV course, and anti-HBV treatment status were used as scoring items based on the propensity score matching (PSM) method. Chronic HBV patients with negative anti-HDV were matched in a ratio of 1∶1. The clinical characteristics of anti-HDV -positive-patients were analyzed. The t-test was used for comparison between groups of normally distributed continuous data. The Wilcoxon signed-rank test was used for comparison between groups of skewness distribution. The χ2 test was used for comparison between groups of enumeration data. Results:The positive detection rates of anti-HDV IgG, anti-HDV IgM, and HDV RNA in 1 830 cases with chronic HBV infection were 2.24% (41/1 830), 1.09% (20/1 830), and 1.69% (31/1 830), respectively. All HDV RNA-positive patients had HDV genotype 1. Two anti-HDV-positive patients had negative hepatitis B surface antigen (HBsAg). Gender, age, HBV course, and anti-HBV treatment status had no significant difference. The quantification of HBsAg, liver biochemical indexes (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bile acids), the proportion of patients with liver cirrhosis, and alpha-fetoprotein were significantly higher in the anti-HDV-positive group than in those in the anti-HDV-negative group ( P<0.05). Conclusion:The prevalence rate of HDV in chronic HBV-infected patients at a single center in the Xinjiang region was 2.24%, with the primary genotype being 1. Furthermore, overlap infection should be paid attention to because it might aggravate liver damage.

Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.
