Objective: To analyze the influencing factors for anterior tibial artery atherosclerosis among patients with hyperuricemia, so as to provide insights into the prevention of anterior tibial artery atherosclerosis. Methods: Patients aged 18 years and older with hyperuricemia in Dazhou Integrated TCM & Western Medicine Hospital were enrolled as research subjects from 2020 to 2023. Demographic information and blood biochemistry indicators were collected through electronic medical records. Anterior tibial artery atherosclerosis was evaluated by color Doppler ultrasound. Factors affecting anterior tibial artery atherosclerosis among patients with hyperuricemia were analyzed by a multivariable logistic regression model. Results: A total of 1 105 patients with hyperuricemia were surveyed, including 862 males (78.01%) and 243 females (21.99%). There were 918 cases (83.08%) at the ages of 60 years and older, and 457 cases (41.36%) with a course of disease at 10 years and longer. The median level of blood uric acid was 480.79 (interquartile range, 98.28) μmol/L. There were 314 cases (28.42%) with anterior tibial artery atherosclerosis. Multivariable logistic regression analysis showed that body mass index (≥24.0 kg/m2, OR=1.597, 95%CI: 1.185-2.151), long-term smoking history (yes, OR=1.709, 95%CI: 1.153-2.534), diabetes mellitus (yes, OR=1.517, 95%CI: 1.162-1.981), serum uric acid (≥480.79 μmol/L, OR=1.667, 95%CI: 1.131-2.457), serum creatinine (≥97 μmol/L, OR=1.685, 95%CI: 1.155-2.460), fasting blood glucose (≥6.1 mmol/L, OR=1.528, 95%CI: 1.106-2.112), fibrinogen (>4 g/L, OR=1.589, 95%CI: 1.091-2.315) and triglycerides (≥1.7 mmol/L, OR=1.879, 95%CI: 1.226-2.881) were influencing factors for anterior tibial artery atherosclerosis among patients with hyperuricemia. Conclusion Anterior tibial artery atherosclerosis among patients with hyperuricemia is associated with long-term smoking, diabetes mellitus, serum uric acid, serum creatinine, fasting blood glucose, fibrinogen and triglycerides high level.

Objective: To discuss the rational drug application of Kawasaki disease in children with upper respiratory tract infection in order to provide reference for the therapy of Kawasaki disease suspected of bacterial meningitis.Methods: The medical record of a 2-year-old boy with Kawasaki disease was retrospectively analyzed, and the anti-infection treatment was analyzed and evaluated.Meanwhile, the mechanism of elevated leukocyte count in cerebrospinal fluid (CSF)of children with incomplete Kawasaki disease was discussed.The pharmaceutical care and treatment results in the diagnosis and treatment process were analyzed as well.Results: The anti-infective therapy in early stage was reasonable as the early symptoms of respiratory tract infection in the child were obvious, however, the choice of aztreonam was defective.On the premise of the clinical diagnosis of Kawasaki disease and excluding bacterial meningitis, the medication was timely adjusted.Finally, the symptoms of the child were improved.Conclusion: The application of anti-infection drugs should be reasonable in clinics, and the abnormality in cerebrospinal fluid should be paid more attention in children with Kawasaki disease.It is necessary to strengthen clinical observation and pharmaceutical care in order to guarantee the safety of medication for patients.

Objective To investigate the effects of vascular endothelial growth factor receptor-1(VEGFR-1) in the invasion and metastasis of hepatocellular carcinoma(HCC)by detecting the expression of VEGFR-1 in HCC tissues.Methods Paraffin-embedded tissue which containing HCC tissues and adjacent tissues were prepared from patients(n=82)with HCC,then were analyzed by immunohistochemical technique for the expression of VEGFR-1,epithelial marker E-cadherin and mesenchymal marker Vimentin.The relationship between the expression of VEGFR-1 and pathological parameters,and the correlation between VEGFR-1 and E-cadherin,VEGFR-1 and Vimentin were analyzed.Results The expression rates of VEGFR-1 in HCC tissues and adjacent tissues were 89%(73/82)and 0,respectively.The difference of VEGFR-1 expression in portal vein tumor thrombus,tumor capsule,stage,size and differentiation grade of tumor had statistical significance(x2=22.192,15.934,16.751,20.154,6.487,P＜0.05).The expression of VEGFR-1 had effect on the 1-,2-year recurrence rate and 2-year survival rate (x2=0.983,0.958,0.847,P＜0.05),but not on 1-year survival rate(x2=0.359,P＞0.05).The expression of VEGFR-1 was negatively correlated with that of E-cadherin(r=0.765,P＜0.01)but positively with that of Vimentin (r=1.469,P＞0.05).Conclusions VEGFR-1 may play an important role in invasion and metastasis of HCC.Epithelial-mesenehymal transition that induced by VEGFR-1 may contribute to the invasion and metastasis of HCC.

Objective To investigate the existence of epithelial-mesenchymal transition(EMT)and its relation to the expression of HBx protein in hepatocellular carcinoma(HCC).Methods The expression of HBx protein,E-cadherin,β-catenin,N-cadherin and fibronectin were detected by immumnohistochemistry technique in 76 cases of HCC.Results Among 76 HCC samples,the loss of expressions of E-cadherin and β-catenin were 34%(26/76)and 20%(15/76),respectively.The positive expressions of HBx protein,N-cadherin and frbronectin were observed in 68%(52/76),55%(42/76),46%(35/76)of HCC samples,respectively.The loss of expression of E-cadherin significantly correlated with the positive expression of N-cadherin and HBx protein (P＜0.01).The positive expression of N-cadherin and fibronectin significantly correlated with the loss of expression of β-catenin and the positive expression of HBx protein(P＜0.05).Conclusions EMT exists in hepatocellular carcinoma,and the expression of HBx is significantly associated with EMT.

Objective To elucidate the experience and attitude of bad news delivery from nurses to advanced cancer patients, in order to offer better nursing care to the dying cancer patients as well as to provide evidence for end-of-life cancer care. Methods A phenomenological research method of qualitative study was employed in this study. Fifteen nurses caring for dying cancer patients were in-depth interviewed with semi-structured interview guide. Colaizzi analytical method was adopted to collect and analyze the data, which was then organized into themes and subthemes. Results Three themes wereconflict between will and behavior barriers of bad news delivery delivery with comprehensive assessment of dying cancer patients. Conclusions Though the oncology nurses thought the dying cancer patients should be told they were dying, few nurses did that. Communication and hope maintenance related to end-of-life cancer care training should be offered to oncology nurses, as well bad news delivery to ensure cancer patients′safety.

Objective To evaluate the endothelial function in diabetic patients by high resolution sonography. Methods The intima-media thicknesses (IMT) of the bilateral carotid artery, femoral artery and the iliac artery of 22 elderly patients and 142 non-elderly patients with diabetes mellitus (DM) and 20 elderly and 20 non-elderly healthy persons were measured. The changes of the diameter of brachial artery were determined by measuring the diameter of brachial artery during reactive hyperemia and after sublingual nitroglycerin. Results The increased percentage of the brachial artery diameter under reactive hyperemia was significantly lower in elderly patients with DM (10. 03?6. 39)% than that in the elderly healthy control (15. 87?4. 79)% (P 0. 05). The IMT in elderly patients with early-stage DM incrassated significantly(P
