ObjectiveTo understand the measles, rubella, and mumps antibody seroprevalence among the children aged 18 years and younger in Karamay City, and to evaluate the effectiveness of vaccination. MethodsA stratified whole cluster random sampling method was used to investigate the antibody seroprevalence of measles, rubella, and mumps among the healthy children aged 18 years and younger in Karamay City, and to further analyze the positive antibody rates and the geometric mean concentration (GMC) of antibodies. ResultsA total of 620 people were investigated, and the positive rates of IgG to measles, rubella, and mumps were 72.74%,62.26%, and 86.45%, respectively, with a GMC of308.94 mIU·mL^-1, 21.81 mIU·mL^-1, and 249.10 U·mL^-1. There were statistically significant differences in the positive rates of antibodies to measles, rubella, and mumps among different age groups (χ²_measles=76.707, P<0.001; χ²_rubella=60.804, P<0.001; χ²_mumps=35.407, P<0.001). The differences in positive rates were statistically significant among individuals with different intervals from the time of their last dose vaccination (χ²_measles=60.533, P<0.001; χ²_rubella=46.331, P<0.001; χ²_mumps=22.825, P<0.001). ConclusionThe antibody levels of measles, rubella and mumps among the people aged 18 years and younger in Karamay City are found to be low. Two doses of measles-mumps-rubella (MMR) vaccine should be given to children born before 2020, and if necessary, supplementary immunization with MMR vaccine should be carried out before they are enrolled in nursery and kindergarten. Additionally, regular population-based antibody surveillance should be conducted to promptly identify the people with weak immunity, which is conducive to effectively reducing and controlling the epidemic situation of measles, rubella and mumps in schools.

OBJECTIVE: To investigate the genetic causal relationship of leukocyte telomere length (LTL) with prostatitis, orchitis and epididymitis by two-sample Mendelian randomization (MR). METHODS: Using LTL as the exposure factor and prostatitis, orchitis and epididymitis as outcome factors, we mined the Database of Genome-Wide Association Studies (GWAS). Then, we analyzed the causal relationship of LTL with prostatitis, orchitis and epididymitis by Mendelian randomization using inverse variance weighting (IVW) as the main method and weighted median and MR-Egger regression as auxiliary methods, determined the horizontal multiplicity by MR-Egger intercept test, and conducted sensitivity analysis using the leaving-one-out method. RESULTS: A total of 121 related single nucleotide polymorphisms (SNPs) were identified in this study. IVW showed LTL to be a risk factor for prostatitis (OR = 1.383, 95% CI: 1.044－1.832, P = 0.024), and for orchitis and epididymitis as well (OR = 1.770, 95% CI: 1.275－2.456, P = 0.000 6). CONCLUSION Genetic evidence from Mendelian randomized analysis indicates that shortening of LTL reduces the risk of prostatitis, orchitis and epididymitis.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

Objective To analyze the caregiver presence needs and their influencing factors among hospitalized elderly non-surgical patients and provide a basis for formulating relevant policies.Methods A descriptive qualitative study method was adopted.Through purposive sampling,semi-structured interviews were conducted on elderly non-surgical patients and their families and medical staff in Peking Union Medical College Hospital from September to October 2023.MAXQDA 2020 and the 7-step phenomenological analysis method of Colaizzi were used to classify and code the interview contents and identify themes.Results The categories of caregiver presence needs of elderly non-surgical patients included basic living assistance needs,disease monitoring needs,psychological support needs,as well as the needs for family members to provide economic support and participate in treatment decision-making.The influencing factors included advanced age,frailty,the lack of self-care ability in patients with comorbidities,the susceptibility of patients to sudden situations during the disease exacerbation period,the increased risk of unexpected events in patients with psychological distress,and patients' concerns about social support and medical decision-making.Conclusion The caregiver presence needs of elderly non-surgical patients during hospitalization are high and influenced by multiple factors.

Objective To investigate the clinical efficacy of Yiqi Huayu Decoction(mainly composed of Astragali Radix,Dioscoreae Rhizoma,Poria,fried Euryales Semen,Ecliptae Herba,Rosae Laevigatae Fructus,charred Crataegi Fructus,Ligustri Lucidi Fructus,Salviae Miltiorrhizae Radix et Rhizoma,and Leonuri Herba)combined with Calcium Dobesilate in the treatment of diabetic nephropathy(DN)with qi deficiency and blood stasis syndrome,and to observe the effect of the therapy on vascular endothelial growth factor(VEGF)and insulin-like growth factor 1(IGF-1).Methods Ninety patients with DN of qi deficiency and blood stasis type were randomly divided into an observation group and a control group,with 45 patients in each group.All patients received basic hypoglycemic therapy and treatment for controlling blood pressure and regulating lipid metabolism disorders.Moreover,the patients in the control group were given Calcium Dobesilate orally,and the patients in the observation group were given Yiqi Huayu Decoction combined with Calcium Dobesilate.The course of treatment lasted for 3 months.The changes of traditional Chinese medicine(TCM)syndrome scores,renal function parameters and serum VEGF and IGF-1 levels in the two groups of patients were observed before and after the treatment,and the clinical efficacy of the two groups was evaluated after treatment.Results(1)After 3 months of treatment,the total effective rate of the observation group was 91.11%(41/45),and that of the control group was 75.56%(34/45).The intergroup comparison(tested by chi-square test)showed that the therapeutic effect of the observation group was significantly superior to that of the control group(P＜0.05).(2)After one month and 3 months of treatment,the TCM syndrome scores of both groups were significantly lower than those before treatment(P＜0.05),and the scores after 3 months of treatment in the two groups were significantly lower than those after one month of treatment(P＜0.05).The intergroup comparison showed that the reduction of TCM syndrome scores of the observation group was significantly superior to that of the control group after one month and 3 months of treatment(P＜0.01).(3)After treatment,the levels of renal function parameters such as serum creatinine(Scr),blood urea nitrogen(BUN),and glomerular filtration rate(GFR)in the two groups of patients were significantly improved compared with those before treatment(P＜0.05),and the observation group's effect on the improvement of all renal function parameters was significantly superior to that of the control group(P＜0.01).(4)After treatment,the serum VEGF and IGF-1 levels in the two groups of patients were significantly lower than those before treatment(P＜0.05),and the observation group's effect on the decrease of serum VEGF and IGF-1 levels was significantly superior to that of the control group(P＜0.01).(5)In the course of treatment,no significant adverse reactions occurred in the two groups of patients,with a high degree of safety.Conclusion Yiqi Huayu Decoction combined with Calcium Dobesilate exerts certain therapeutic effect in treating DN patients with qi deficiency and blood stasis syndrome.The combined therapy can effectively down-regulate the serum levels of VEGF and IGF-1,significantly improve the renal function,and alleviate the clinical symptoms of the patients,with a high degree of safety.

Objective:To investigate the efficacy and side effects of concurrent chemoradiotherapy with or without nimotuzumab in the treatment of locally advanced nasopharyngeal carcinoma after neoadjuvant chemotherapy.Methods:In the prospective study, 100 patients with stage Ⅲ-Ⅳa locally advanced nasopharyngeal carcinoma (except T 3N 0M 0 stage) who met the inclusion criteria were randomly divided into the experimental and control groups using the random number table method. Patients in both groups were treated with neoadjuvant chemotherapy using TPF (paclitaxel liposome, cisplatin, and 5-fluorouracil) regimen for 2 cycles. At 2 weeks after chemotherapy, concurrent chemoradiotherapy plus nimotuzumab targeted therapy was given in the experimental group, and concurrent chemoradiotherapy was delivered in the control group. The main observation index was the distant metastasis-free survival (DMFS) rate. Log-rank test and multivariate Cox regression analysis were used. Results:The objective remission rate and complete remission rate in the experimental and control groups were 100% vs. 98% ( P=1.000) and 92.0% vs. 80% ( P=0.084). The 3-year DMFS in the experimental and control groups were 91.4 % vs. 76.1 % ( P=0.043). The 3-year progression-free survival (PFS), locoregional recurrence-free survival (LRFS) and overall survival (OS) in two groups were 87.3 % vs. 74.1 % ( P=0.097), 94.5 % vs. 85.6 % ( P=0.227) and 90.5% vs. 85.2% ( P=0.444). Subgroup analysis showed that patients with age<60 years ( HR=0.34, 95% CI=0.12-0.94, P=0.037), neutrophil-to-lymphocyte ratio (NLR)≤4 ( HR=0.34, 95% CI=0.13-0.89, P=0.028) received concurrent chemoradiotherapy plus nimotuzumab obtained better PFS. Multivariate analysis showed that NLR was an independent risk factor for disease progression ( HR=5.94, 95% CI=1.18-29.81, P=0.030) and distant metastasis ( HR=13.76, 95% CI=1.52-124.36, P=0.020). Conclusions:Compared with concurrent chemoradiotherapy alone, concurrent chemoradiotherapy combined with nimotuzumab after neoadjuvant chemotherapy can significantly increase DMFS rate for patients with locally advanced nasopharyngeal carcinoma. The incidence of side effects is similar in two groups. Concurrent chemoradiotherapy plus nimotuzumab after neoadjuvant chemotherapy may be a preferred treatment strategy for locally advanced nasopharyngeal carcinoma.

ObjectiveTo analyze the epidemiological characteristics of varicella in Karamay City, to inform the prevention and control of the local varicella epidemic, and to guide adjustments to the varicella vaccine immunization strategy. MethodsThe data on varicella cases from 2015 to 2022 in Karamay were collected and the epidemiological characteristics were analyzed. ResultsA total of 3 380 varicella cases were reported in Karamay from 2015 to 2022, with an average annual incidence rate of 94.91/10⁵. The incidence of varicella showed a year-on-year downward trend from 2015 to 2022 (AAPC=-16.29%, P<0.05). Varicella cases demonstrated a seasonal variation, with peak incidence occurring from October to January of the following year and a slight increase from April to June. There were regional differences in the distribution of incidence rate, with 109.68/10⁵ in Karamay District, followed by 89.06/10⁵ in Baijiantan District, and 53.80/10⁵ in Dushanzi District, respectively. The incidence rates in the 10‒14 and 5‒9 years age groups were higher than that in other age groups, with an incidence rate of 447.01/10⁵ and 422.33/10⁵ in each group, respectively. Most of the cases were students, accounting for 59.17% of the total cases, followed by preschool children (17.40%). There were 645 breakthrough cases of varicella, accounting for 19.08% of the total cases. The average interval between the onset of breakthrough cases and the most recent vaccination was (5.77±3.43) years. ConclusionVaricella cases mainly occurred in schools and childcare institutions in Karamay City, highlighting the need for enhanced prevention and control efforts in these settings. A second dose of varicella vaccine is recommended for children before primary school enrollment.

Background and Objective Accurate diagnosis of mucous cystic lesion(PCL)remains a clinical difficult.Both Carcinoembryonic antigen(CEA)and glucose(GLU)are reported to have ability to distinguish mucinous PCL from non-mucinous PCL,but the accuracy was limited.The objective of this study was to evaluate the value of cystic CEA combined with GLU in the diagnosis of mucinous PCL.Methods PCL patients who underwent pancreatic surgery and endoscopic ultrasonography guided fine-needle aspiration(EUS-FNA)were retrospectively collected from the First Affiliated Hospital of Naval Medical University.Clinical data and cystic fluid analysis of included PCLs patients were analyzed using receiver operator(ROC)curves.ROC analysis,sensitivity and specificity analyses were used to evaluate the value of CEA combined with GLU in the diagnosis of mucinous PCL.Results From January 2015 to December 2021,a total of 84 patients underwent cyst fluid CEA and GLU analysis,of whom 44(52.4％)had mucinous PCL and 40(47.6％)had non-mucinous PCL.The AUC for distinguishing mucinous from non-mucinous PCL by CEA was 0.82[(95％confidence interval(CI):0.72-0.92)].When 192 ng/mL was used as the cutoff level,the diagnostic sensitivity and specificity were 50％and 93％,respectively.Using 20 ng/mL as cutoff level,the diagnostic sensitivity increased to 80％and the specificity decreased to 68％.The AUC for the cystic GLU to distinguish mucinous from non-mucinous PCL was 0.73(95％CI:0.99-0.87),and the diagnostic sensitivity and specificity were 100％and 60％,respectively.When the cutoff level of CEA was 192 ng/mL,the AUC of CEA combined with GLU in the diagnosis of mucinous PCLs was 0.94(95％Cl:0.86-0.99),while when the cutoff level of CEA was 20 ng/mL,the AUC of CEA combined with Glu in the diagnosis of mucinous PCLs was 0.94(95％CI:0.85-0.99).The AUCs were significantly higher than the AUC with single diagnostic indicators.Conclusion When using the cutoff level of 192 ng/mL,cyst fluid CEA combined with GLU has high sensitivity and specificity in differentiating mucinous PCL from non-mucinous PCL,so it can be considered for clinical application.Lower CEA cutoff level(20 ng/mL)can improve the sensitivity of diagnosis.
