Objective To assess the clinical outcomes about the visual qulitity of toric implantable contact lens ( TICL) implantation for high myopia with astigmatism. Methods Fifty-two eyes of 27 patients that underwent TICL implantation were examined. Uncorrected visual acuity( UCVA) ,best corrected visual acuity( BCVA) ,refraction,contrast sensitivity ( CS) with and without glare were evaluated before and after the treatment. Results Significant improvement in UCVA and BCVA were found at 1 month and 6 months after treatment (P<0. 05). The refraction at 1 month ( -0. 56 ± 0. 42)D and 6 months ( -0. 58 ± 0. 22)D after treatment were of no significant difference (P>0. 05), and the astigmatism at 1 month ( -0. 35 ± 0. 60)D and 6 months ( -0. 31 ± 0. 42)D after treatment were of no significant difference either (P>0. 05). The CS with and without glare were all significantly better than results before operation for 6. 0,12. 0 and 18. 0 cycles/degree (P<0. 05),but there were no significant difference between 1 month and 6 months after treatment (P>0. 05). No significant difference were found preoperatively,1 month after treatment and 6 months after treatment in terms of CS with and without glare (P>0. 05). The satisfaction of this investigation was 100%. Conclusion The TICL performed well in correcting high myopia with astigmatism,and it is a good surgical option for the treatment.

A highly stable multilayer film modified glassy carbon electrode (GCE) containing polydopamine (PDA) and Cu microparticles was fabricated by layer-by-layer self-assembly technique. The fabrication process was based on the self-polymerization of dopamine and electroless deposition of Cu microparticles on PDA coating. The fabrication process of multilayer films was characterized by UV-Vis spectra. The electrochemical performance of GCE / (PDA/ Cu) n modified electrode for glucose detection was investigated by cyclic voltammetry and amperometric current-time curve under alkaline conditions. At detection potential of 0. 35 V, the GCE / ( PDA/ Cu) 4 modified electrode presented a linear range of 0. 5 - 9. 0 mmol/ L with a detection limit of 5. 8 μmol/ L (S / N=3). Moreover, the sensitivity of the modified electrode was tunable by controlling the number of bilayers of the multilayer films. The modified electrode showed highly selective, stable and fast amperometric sensing of glucose. It was applied to determine glucose in human blood serum with satisfactory results.

Objective To evaluate the prevalence and potential risk factors for pulmonary hypertension in the elderly hospitalized patients. Methods1093 elderly hospitalized patients aged (80.8 ± 9.8) years were examined by Doppler echocardiography for evaluating pulmonary hypertension which defined by pulmonary artery systolic pressure (PASP)≥40 mm Hg (1 mm Hg=0.133 kPa).The relative clinical testing data were collected. Results 115 patients (10.5％) of the elderly patients were diagnosed as pulmonary hypertension.The prevalence of pulmonary hypertension in patients aged 85-100 years was 16.4％ (82/500),which was higher than in other ages. In the multivariate logistic regression analysis,age (OR=1.085,95％CI=1.025-1.148,P=0.005),left ventricular diastolic dysfunction (OR =3.954,95 ％ CI =1.812-8.627,P=0.001 ),internal diameter of right ventricle (OR=1.271,95％CI=1.112-1.452,P=0.000) and internal diameter of left atrium (OR=1.100,95％CI=1.013-1.194,P=0.023) were risk factors for pulmonary hypertension.ConclusionsThe prevalence of pulmonary hypertension is high in the elderly hospitalized patients,especially those aged 85 years and over,complicated with left ventricular diastolic dysfunction and enlargement of right ventricle and left atrium.

ObjectiveTo investigate the relationship between high-sensitivity C reactive protein （hs-CRP） and oxygen uptake efficiency slope (OUES) in patents with cardiovascular disease. MethodsExercise tests, following a symptom-limited standard Bruce protocol with simultaneous respiratory gas-exchange measurements, were performed on a treadmill in 17 post-PCI patients, 21 stable angina pectoris and 24 patients with essential hypertension (EH). The oxygen uptake (VO2), minute ventilation (VE) were determined. The OUES was derived from the relation between VO2 (ml/min) and VE (L/min) during incremental exercise and was determined by VO2=a×lgVE+b, where a = OUES. The OUES was calculated from data of the first 75% (OUES75) and 100% (OUES100) of exercise duration. The serum hs-CRP was measured by immunoassays, and the left ventricular ejection fraction (LVEF) was measured with echocardiography. ResultsOUES75 （r=-0.506,P＜0.001）, OUES100 （r=-0.567,P＜0.001） and LVEF （r=-0.286,P＜0.01） were correlated with lg(hs-CRP). In stepwise multivariable linear regression models, lg(hs-CRP) （β=-0.374，P=0.006）, body height （β=-1.854，P=0.036）, body weight （β=-5.033，P=0.034）were independent risk factors of lower OUES75. lg(hs-CRP) （β=-0.396，P=0.003）, body height （β=-2.157，P=0.013）, body weight （β=-5.912，P=0.011） were independent risk factors of lower OUES100. ConclusionThe serum leveles of hs-CRP may be the useful marker that reflecting cardiopulmonary functional reserve and left ventricular function.

Objective To evaluate the effect of different doses of thoracic radiotherapy (TRT) upon the clinical prognosis of patients with extensive-stage (stage Ⅳ) small cell lung cancer (ES-SCLC) and establish a Nomogram prediction model.Methods Clinical data of 144 patients pathologically diagnosed with ES-SCLC undergoing TRT in Tianjin Medical University Cancer Hospital from month,2010 to month,2016 were retrospectively analyzed.Clinical characteristics,treatment data and responses were evaluated.A Nomogram was established by using Cox's proportional hazard regression model to predict the overall survival (OS).The prediction capability and accuracy were assessed by the concordance index (C-index) and a calibration curve between the model and verification groups.Results The median follow-up time was 31.9 months.The 2-year OS rate was 20.3％.The Nomogram model demonstrated that TRT dose,liver metastases,oligometastases/polymetastases,number of chemotherapy cycle and response to chemotherapy were significantly correlated with clinical prognosis.The calibration curve revealed that the predicted and actual OS were highly consistent.The C-index was calculated as 0.701.In the subgroup analyses,patients with high-dose TRT obtained significantly better OS than their counterparts with low-dose TRT.Conclusion The Nomogram prediction model based on different TRT doses can accurately predict the OS rate of ES-SCLC patients,which is an individualized model for predicting the survival probability.

OBJECTIVETo observe the clinical characteristics and short-term survival of patients with splenomegaly and acute-on-chronic liver failure related to chronic HBV infection.

METHODSElectronic medical records of patients with acute-on-chronic liver failure were collected to analyze the clinical parameters and 4-week survival of patients with or without splenomegaly.

RESULTSOf the 149 patients enrolled, the overall 28-day mortality rate was 48.3%, which was lower in patients with enlarged spleen than those without (34.2% vs 54.1%, P=0.034). Compared with patients without splenomegaly, patients with splenomegaly had lower platelet counts (P=0.001), lower ALT levels (P=0.005) and lower PT-INR (P=0.010). Although the occurrence of hepatic encephalopathy was comparable between patients with or without splenomegaly, severe conditions were more frequent in those without splenomegaly. Hepatic encephalopathy grades, serum creatinine levels, neutrophil percentages over 70%, PT-INR and splenomegaly were independent factors associated with the 28-day survival, and this novel model was superior to model of end-stage of liver disease in predicting the 4-week survival (P=0.017).

CONCLUSIONPatients with splenomegaly that evolves into acute-on-chronic liver failure have unique clinical characteristics and further clinical observations are warranted.

OBJECTIVES: The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States. METHODS: The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures. RESULTS: For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001). CONCLUSIONS From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

Objective:To explore the optimal matching of the current parameters about artificial facial nerve (AFN) for inducing contraction of the orbicularis oris muscle (OOM) in rabbit with peripheral facial paralysis.Methods:According to the combinations of different stimulus parameters, at different time points, we used AFN to induce contraction of the affected side OOM of the paralyzed rabbit in waking state. We recorded the current amplitudes of the threshold stimulation and peak stimulation under each combination, then compared the total charge of the stimulus consumption under different combinations.Results:Compared the total stimulus charge consumption of the AFN threshold stimulation and that in the peak stimulation respectively under different stimulus frequency and pulse width matching combinations, we found that the frequency, the pulse width and the interaction of the frequency and pulse width among different groups could affect the total charge, the differences were statistically significant ( P<0.05). Conclusions:When AFN stimulus frequency is 60 Hz and the stimulus pulse width is 100 μs, the output current intensity is relatively lowest and the total consumed charge is the lowest under the premise of effectively inducing the paralytic side OOM contraction. Thus we recommend this stimulus parametric combination as the optimal combination for meeting the low power consumption of AFN.

Objective:To explore the effects of hospital-to-community model-based case management on outcomes and life quality of patients with atrial fibrillation.Methods:By convience sampling method, a total of 90 cases of atrial fibrillation patients admitted to Changzhou Second People′s Hospital from January 2019 to May 2020 were randomly divided into control group and experimental group, with 45 cases in each group. The patients in the control group received routine nursing care, the experimental group implemented hospital-to-community model-based case management. The beliefs about medicine, medication compliance, quality of life and readmissions of cardiovascular events were compared between 2 groups before and 6 months after intervention.Results:Finally, 41 cases were included in the experimental group and 38 cases in the control group. Before intervention, there were no significant differences in various indexes between the two groups ( P>0.05). After 6 months of intervention, the scores of specific-necessity in Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Morisky Medication Adherence Scale-8 (MMAS-8) were (16.98 ± 4.22) and (7.15 ± 0.69) points in the experimental group, higher than in the control group (14.95 ± 4.33) and (6.32 ± 1.07) points; the scores of specific-concerns in BMQ-Specific were (6.83 ± 1.91)points in the experimental group, lower than in the control group (8.42 ± 2.73) points. The differences were statistically significant ( t = 2.11, 4.07, 2.98, all P<0.05); the scores of physical function, role-physical, pain, general health, mental health dimensions and total scores in SF-36 were (80.37 ± 3.46), (46.63 ± 14.54), (90.37 ± 5.78), (70.07 ± 9.98), (84.20 ± 8.73) and (584.88 ± 25.71) points in the experimental group, higher than in the control group (70.13 ± 11.20), (37.34 ± 10.25), (83.37 ± 6.89), (59.55 ± 7.98), (77.58 ± 9.09) and (533.87 ± 31.62) points, the differences were statistically significant ( t values were 3.30-7.89, all P<0.05). At 6 months after discharge, the re-admission of cardiovascular events were 5 cases (12.2%) in the experimental group and 12 cases (31.6%) in the control group, the difference was statistically significant ( χ2=4.74, P<0.05). Conclusions:Hospital-to-community model-based case management can effectively promote beliefs about medicine and medication compliance, improve quality of life and decrease re-admission of cardiovascular events of patients with atrial fibrillation.
