Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

Massive hemoptysis is one of the most dreaded of all respiratory emergencies and can have a variety of underlying causes. It is mostly caused by bleeding from bronchial circulation. Bronchial artery embolization is now considered to be the treatment of choice for acute massive hemoptysis. Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis. However, nonbronchial systemic arteries can be a significant source of massive hemoptysis and a cause of recurrence after successful BAE. So knowledge of the bronchial artery anatomy, together with an understanding of the pathophysiologic features of massive hemoptysis, are essential for planning and performing BAE in affected patients. In addition, interventional radiologists should be familiar with the techniques, results, efficacy, safety and possible complications of BAE and with the characteristics of the various embolic agents. Bronchial arterial catheterisation in human via a percutaneous approach has been practiced for 32 years (1973) in the world and 20 years (1986) in China, initially for direct chemotherapy treatment for bronchial malignancies and then for the embolization of patients with massive haemoptysis. A review of clinical experience to evaluate technique,embolic materials,outcome and complications of BAE is presented.

Objective:To explore the clinical value of syndecan-1 (SDC1), asymmetric dimethylarginine (ADMA) assessment in the early diagnosis and course monitoring of patients with type 2 diabetic kidney disease (DKD).Methods:This is a cross-sectional study. A total of 232 patients with type 2 diabetes admitted to the Department of Endocrinology of Kailuan General Hospital from December 2020 to December 2021 were included. The general biochemical indexes, SDC1 and ADMA were detected. According to urinary albumin/creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR), patients were divided into simple diabetes group (50 cases) and DKD group (182 cases). According to the risk of progression of DKD, the DKD group was further divided into low-progression diabetic nephropathy (LDKD) subgroup (90 cases), medium-progression diabetic nephropathy(MDKD)subgroup (55 cases), and high-progression diabetic nephropathy(HDKD) subgroup (37 cases). Forty healthy people undergoing physical examination during the same period in our hospital were selected as the healthy control group. According to the quartile value of N-acetyl-β-D-glucosaminase/urinary creatinine (NAG/Ucr), the DKD group was divided into Q1- Q4 subgroups, with 45, 45, 46 and 46 cases, respectively. Spearman correlation was used to analyze the correlation between SDC1, ADMA and glomerular and renal tubule injury indexes in DKD patients. Multifactor ordered Logistic regression was used to analyze the influencing factors of the progression risk of DKD and renal tubular injury. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of SDC1 and ADMA for DKD. Results:The levels of systolic blood pressure, diastolic blood pressure, triglyceride (TG), serum creatinine (Scr), uric acid (UA), NAG/Ucr, SDC1 and ADMA in DKD group were higher than those in SDM group and healthy control group (all P<0.05). The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and hemoglobin A1c (HbA 1c) in DKD group were higher than those in healthy control group, and the level of high density lipoprotein cholesterol (HDL-C) was lower than that in healthy control group (all P<0.05). The SDC1 level in HDKD subgroup was higher than that in SDM group and LDKD subgroup, and the ADMA level was higher than that in SDM group and lower than that in LDKD subgroup (all P<0.05). SDC1 level in MDKD subgroup was higher than that in SDM group and LDKD subgroup, ADMA level was higher than that in SDM group, but lower than that in LDKD subgroup (all P<0.05).The levels of SDC1 and ADMA in LDKD subgroup were higher than those in SDM group (all P<0.05). The levels of TC, AporB, HbA 1c, Scr, UACR and SDC1 in NAG/Ucr Q4 subgroup were higher than those in Q1 subgroup, the levels of Scr, UACR and SDC1 were higher than those in Q2 subgroup, and the levels of HbA 1c, Scr, UACR and SDC1 in Q3 subgroup were higher than those in Q1 subgroup (all P<0.05). Spearman correlation analysis showed that SDC1 was positively correlated with UACR, NAG/Ucr ( r=0.757, 0.566, all P<0.05),and was negatively correlated with eGFR ( r=-0.337, P<0.05). ADMA was positively correlated with UACR, NAG/Ucr ( r=0.197, 0.142, all P<0.05). Multifactor ordered Logistic regression analysis showed that SDC1, NAG/Ucr and Scr were the independent influencing factors of progression risk in DKD patients ( OR=2.043, 1.067, 1.047, 0.660, 1.394, all P<0.05), while SDC1, HbA 1c and ACR were the independent influencing factors of renal tubule injury in DKD patients ( OR=1.177, 1.193, 1.002,all P<0.05). ROC curve showed that the area under the curve (AUC) of SDC1 for DKD diagnosis was 0.979, the sensitivity was 92.31%, and the specificity was 92.22%, while the AUC of ADMA for DKD diagnosis was 0.745, the sensitivity was 81.32%, and the specificity was 60.00%. The AUC, sensitivity and specificity of the combined diagnosis of DKD were 0.981, 90.66% and 95.66%. Conclusions:SDC1 is an independent risk factor of DKD progression and tubular injury in DKD patients, which can be used to diagnose early DKD and monitor the progression of DKD. ADMA is suitable for early screening of DKD.

Objective: To explore the relationship between dietary behavior, dietary frequency and central precocious puberty (CPP) among children in Wuhan, so as to provide a scientific basis for elucidating the possible and related dietary factors leading to precocious puberty. Methods: From February to December 2023, 100 children with CPP and 100 healthy children were collected in Wuhan Children s Hospital for a case control study. Questionnaires and interviews were used to collect demographic information, child lifestyle, as well as dietary behavior and dietary frequency in the past six months. Conditional Logistic regression model was used to analyze the relationship of children s dietary behavior and dietary frequency with CPP. Results: No associations were found between three dietary behavior, including emotional eating, restrictive eating, and external eating, with CPP at baseline ( P >0.05). In the association analysis of dietary frequency and CPP, the risk of CPP was higher in those who consumed red meat >5 times/week ( OR =1.93, 95% CI =1.01-3.68), carbonated beverages ≥4 times/month ( OR =2.70, 95% CI =1.03-7.08), fruit juices ≥4 times/month ( OR =2.31, 95% CI =1.02-5.25), and nutritional supplementation ( OR =2.77, 95% CI =1.47- 5.22 ), whereas the risk of CPP was lower in those who consumed nuts ≥4 times/month ( OR =0.21, 95% CI =0.08-0.57) ( P < 0.05 ). Conclusion Consumption of higher amounts of red meat, high frequency of carbonated and juice based sugary drinks, and nutrient supplementation may be contributing factors to the development of CPP, whereas regular consumption of nuts is less likely to be associated with the development of CPP.

Objective:To explore the experience and feelings of undergraduate nurses in low-value care de-implementation, so as to provide reference for formulating specific strategies for low-value care de-implementation.Methods:From July to October 2023, purposive sampling was used to select 14 full-time undergraduate nurses from the First Affiliated Hospital of Zhengzhou University as research subjects. The phenomenological research method was used to conduct semi-structured in-depth interviews, and Colaizzi 7-step analysis method was used to analyze the data.Results:Three themes were extracted in total. Highly recognizing the low-value care de-implementation included reducing nurses' workload, improving patients' medical experience, and promoting harmonious nurse-patient relationships. Cognitive dissonance for low-value care de-implementation involved low efficiency cognition and maintaining a wait-and-see attitude. Low-value care de-implementation was hindered by multiple factors, including a lack of critical thinking, concerns about medical nursing risks, a lack of evidence-based nursing skills, a lack of organizational support, and a lack of medical knowledge among patients.Conclusions:Undergraduate nurses highly recognize the significance of low-value care de-implementation, but still face many challenges in their clinical practice. Multiple measures should be taken to promote the low-value care de-implementation in clinical practice.

Objective To investigate the effect and the mechanism of epithelial-mesenchymal transition (EMT) in renal tubular cells induced by uric acid.Methods Normal rat kidney tubular cell line (NRK-52E) were exposed to different concentrations of uric acid (100,200,400,600,800 μmol/L UA) for 48 hours to induce EMT.Morphological changes of the NRK-52E cells were examined under an inverted phase contrast microscope.The protein expression of E-cadherin,α-SMA,p-Akt and Akt were detected by Western blotting.The distribution of E-cadherin and α-SMA were detected by immunofluorescence.NRK-52E cells were pretreated by different concentrations of LY294002(0,2.5,5,10,15 μmol/L),the inhibitor of PI3K/p-Akt signaling pathway,and then processed by uric acid (400 μmol/L) for 48 hours.Western blotting was used to detect the protein expression of p-Akt and Akt.NRK-52E cells were then divided into four groups:normal group (N),uric acid group (UA),LY294002 group (LY),uric acid with LY294002 group (UA + LY).The protein expression of E-cadherin and α-SMA were detected by Western blotting,the distribution of E-cadherin,α-SMA and p-Akt were detected by immunofluorescence.Results There was abundant cellular expression of E-cadherin in unstimulated renal tubular cells whereas its expression was significantly decreased in uric acidstimulated cells (P ＜ 0.05).In addition,uric acid induced de novo expression of α-SMA in contrast to almost negative staining in untreated cells (P ＜ 0.05).p-Akt were obviously increased in high uric acid group (P ＜ 0.05) and Akt changed not significantly (P ＞ 0.05).NRK-52E cells transformed into elongated fibroblast-like cells from cuboidal clustered epithelial cells.These indicated that uric acid has induced EMT and activated PI3K/p-Akt signaling pathway in NRK-52E cells.However,the above effects of uric acid were abolished when p-Akt was blocked by the PI3K inhibitor (10,15 μmol/L LY294002),indicated that LY294002 has reversed the trend of EMT.Conclusions High uric acid induces phenotypic transition of renal tubular cells probably via activating PI3K/Akt signaling pathway.

Objective To assess the impact of physical training on physiological function of adult renal transplant recipients by meta-analysis and to provide theoretical guidance for clinical practice.Methods Randomized controlled trials of physical training for the treatment of renal transplant recipients until October 2017 were searched in the database of Cochrane library,PubMed,Embase,Web of Science,Wanfang Data and CNKI.Data extracted from the literatures were analyzed with RevMan software (version 5.3).Results A total of 10 studies in 10 manuscripts met the inclusion criteria,and 557 cases were included.Meta-analysis results were as follows.Compared with the control group (routine drug therapy),the level of peak exercise oxygen uptake (peak VO2) was significantly increased in physical training group (routine drug therapy and physical training) (MD=2.40,95％ CI 0.15-4.64,P=0.04).However,there was no statistically significant difference in the change of blood lipid,blood pressure,hemoglobin and serum creatinine between the two groups (all P ＞0.05).Conclusions Physical training can improve cardio respiratory fitness of renal transplant recipients in the early stage,but it has no obvious effect on blood pressure,blood lipid,hemoglobin and blood creatinine.

OBJECTIVETo investigate the significance of NADPH quinine oxidoreductase 1 (NQO1) protein overexpression on prognostic evaluation of head and neck squamous cell carcinoma (HNSCC).

METHODSNQO1 protein was detected in 162 of HNSCC, 45 cases of adjacent nontumor tissues and 26 samples of normal head and neck epithelia using EnVision immunohistochemical. Correlation between NQO1 overexpression and patients prognosis was also analyzed.

RESULTSThe positive rate and strongly positive rate of NQO1 protein were 84.0% (136/162) and 69.8% (113/162) in HNSCC, respectively, and both of which were significantly higher than either those in adjacent nontumor tissues and normal head and neck epithelia (both P < 0.01). NQO1 expression was significantly correlated with the clinical stage, pT and chemoradiotherapy of HNSCC (P < 0.01). Kaplan-Meier survival analysis showed that overall survival and disease-free survival rates were significantly higher in HNSCC patients with high level NQO1 expression than that those with low level of NQO1 expression (Log-rank = 6.625 , P = 0.010;Log-rank = 6.234 , P = 0.013). Additional analysis by Cox proportional hazard regression model showed that high level of NQO1 expression was an independent hazard predictor for overall survival of patients with HNSCC (Wald = 6.626, P = 0.008).

CONCLUSIONSNQO1 expression level is closely correlated with the progression and prognosis of patients with HNSCC. High level of NQO1 expression may be used as an important indicator for patients with poor prognostic HNSCC.
