[Application progress of quality of life assessment scales and psychological assessment tools for evaluating overall quality of life in patients with uveitis].

Uveitis is a common sight-threatening ocular disease that has multiple heterogeneous clinical entities, complicated pathogenesis, and a high complication rate. The visual impairment caused by uveitis, the side effects of long-term systemic therapy, and the economic burden due to the high cost of treatment have a significant impact on the patient's physical, psychological, and social functions, resulting in a decrease in the quality of life of uveitis sufferers. Accurate assessment of patients' quality of life is helpful to guild treatment, enhance compliance and improve patients' overall quality of life. This article reviews the current progress on the quality of life assessment scales and psychological assessment tools to evaluate overall quality of life in patients with uveitis, thereby to provide reference and theoretical basis for selecting and developing the quality of life assessment tools for uveitis patients.

[Monitoring of major occupational diseases and analysis of occupational group's health status of Jining in 2018].

Objective: To analyze the major occupational disease surveillance and the occupational health examination of Jining in 2018, provide the basis for the government department formulating occupational disease prevention measures. Methods: In January 2019, collecting data of the occupational disease and Occupational Health Information Surveillance Network in Jining from January 1 to December 31, 2018, 37295 workers were collected, and 37295 workers who were exposed to key occupational disease risk factors and underwent occupational health check-up during their working period. The contact of occupational Hazard Factors and occupational health examination were analyzed. SPSS 22.0 was used to set up the database for statistical analysis. Results: Workers exposed to major occupational hazards were more exposed to noise (56.34%, 39935/70883) , coal dust (15.65%, 11095/70883) , welding fume (10.25%, 7262/70883) , silicon dust (5.61%, 3975/70883) . In 2018, 24 cases (38.71%, 2462) of coal worker's pneumoconiosis, 21 cases (33.87%, 2162) of silicosis, 8 cases (12.90%, 82) of noise deafness and 8 cases (12.90%, 862) of brucellosis were the major occupational diseases reported. The abnormal rate of lung function examination was 14.87% (461/3100) , and the abnormal rate of high frequency hearing threshold examination was 4.56% (1492/32731) in workers exposed to coal dust (coal-silica dust) , the difference was statistically significant (P<0.01) . Conclusion: Jining should strengthen the supervision of enterprises with key occupational disease hazards, formulate classified supervision and management methods, and improve the occupational health inspection rate of workers.

[Value of four-dimensional echocardiography combined with speckle tracking technique on the assessment of right heart function and prognosis in patients with pulmonary arterial hypertension].

Objective: To investigate the value of four-dimensional echocardiography combined with speckle tracking technique on the assessment of right heart function and prognosis in patients with pulmonary arterial hypertension (PAH). Methods: In this prospective study, 51 patients with PAH diagnosed by right heart catheterization in east hospital and south hospital of Renji hospital affiliated to school of medicine of Shanghai Jiaotong University from September 2015 to July 2017 were enrolled as PAH group from July to November 2017. Meanwhile, 26 healthy volunteers with age and sex matched with pulmonary hypertension patients were recruited as control group. The patients were aged (45.8±15.5) years old in PAH group, and there were 6 males and 45 females. The healthy volunteers were aged (45.4±14.6) years old in control group, and there were 4 males and 22 females. Two-dimensional and four-dimensional echocardiographic images were obtained to measure the structure and function of the right heart. The myocardial strain of each ventricle and atrium was measured by sparkle tracking. The patients in PAH group were followed up from July 2017 to August 2018 to observe the endpoint events including all-cause death, re-hospitalization, and clinical deterioration. Results: There were significant differences in two-dimensional echocardiographic parameters(including tricuspid annular plane systolic excursion (TAPSE), right ventricular area change fraction (FAC), and right ventricular systolic pressure (RVSP)), speckle tracking parameters (including global longitudinal systolic peak strain of left ventricle (LVGLS), global longitudinal systolic peak strain of right ventricle (RVGLS),left atrial reservoir function(LASr), left atrial conduit function (LASc), left atrial pump function (LASp), right atrial reservoir function (RASr), right atrial conduit function (RASc), and right atrial pump function (RASp)), and four-dimensional echocardiographic parameters(including right ventricular end diastolic volume (RVEDV) , right ventricular end systolic volume(RVESV), right ventricular stroke volume(RVSV), right ventricular freewall longitudinal strain(RVLSf), interventricular septum longitudinal strain(IVSLS), right ventricular ejection fraction(RVEF)) between control group and PAH group (all P<0.01 or 0.05).Spearman correlation analysis showed that RVEF was correlated with 6-minute walking distance (r=0.540, P<0.001), B-type natriuretic peptide (r=-0.545,P<0.001), New York Heart Association (NYHA) cardiac function classification(r=-0.583, P<0.001), TAPSE(r=0.595, P<0.001), LVGLS (r=-0.461, P=0.001) ,LASc (r=0.453, P=0.002) ,RASc (r=0.532, P<0.001) ,RVESV (r=-0.418, P=0.004) , RVSV (r=0.351, P=0.017) , and IVSLS (r=-0.450, P=0.002) . Pearson correlation analysis also showed that RVEF was correlated with FAC(r=0.579, P<0.001),RVSP (r=-0.442, P=0.002) ,RVGLS (r=-0.521, P<0.001) , LASr (r=0.483, P=0.001) , RASr (r=0.617, P<0.001) , RASp (r=0.513, P<0.001) , and RVLSf (r=-0.592, P<0.001) .After a follow-up of (10.4±2.7) months, there were 4 all-cause deaths, 5 re-hospitalizations and 5 clinical deterioration. Multivariate Cox regression analysis showed that increased RVEF was independent protective factor for end-point events in PAH patients (HR=0.702, P=0.043), and increased RVSP was independent risk factor for end-point events in PAH patients (HR=1.083, P=0.017). The receiver operating characteristic (ROC) curve showed that RVEF and RVSP could be used to predict the end-point events in PAH patients. The area under the curve (AUC) was 0.835(P=0.001) and 0.820(P=0.001), respectively. Conclusions: RVEF measured by four-dimensional echocardiography is correlated with right ventricular function parameters measured by two-dimensional echocardiography and can be used to estimate the prognosis of PAH patients. The right atrial and left atrial function assessed by speckle tracking can also reflect the right ventricular function to a certain extent.

Semi-quantitative assessment of the presence and Child-Pugh class of hepatitis B related cirrhosis by using liver lobe-based dynamic contrast-enhanced MRI.

AIM: To determine whether liver lobe-based DCE-MRI can be used to detect the presence and Child-Pugh class of hepatitis B-related cirrhosis. MATERIALS AND METHODS: Fifty-six cirrhotic patients with hepatitis B and 20 healthy participants underwent liver DCE-MRI, and the positive enhancement integral (PEI), time to peak (TTP), maximum slope of increase (MSI) and maximum slope of decrease (MSD) of the left lateral liver lobe (LLL), left medial liver lobe (LML), right liver lobe (RL), and caudate lobe (CL) were measured and analysed statistically to evaluate cirrhosis. RESULTS: TTP values of the LLL, LML, RL and CL were positively correlated with the Child-Pugh class of cirrhosis (r=0.452 to 0.55, all p<0.05). PEI values of the LLL, LML, RL and CL, as well as the MSI of the CL and the MSD of the RL, were inversely correlated with the Child-Pugh class (r=-0.349 to -0.72, all p<0.05). PEI values of the LLL and CL, or TTP values of the RL had the most area under receiver operating characteristic curve (AUC) of 0.99 for identifying the presence of liver cirrhosis. The PEI of the RL had the largest AUC of 0.975 and 0.78 for distinguishing the Child-Pugh class A of cirrhosis from class B-C and class A-B of cirrhosis from class C, respectively. CONCLUSION: Liver lobe-based DCE-MRI parameters are associated with the presence and Child-Pugh class of hepatitis B-related cirrhosis.

Real-time quantitative assay of HCV RNA using the duplex scorpion primer.

A novel real-time quantitative method for detecting HCV in serum was established in which the duplex scorpion primer was used to provide a unimolecular probing mechanism for hybridizing the highly conserved 5' noncoding region (5' NCR) of the HCV genome specifically. Through methodological evaluation, we found this new method had a wide linearity, high sensitivity, repeatability and specificity. Compared to the commercial TaqMan method, this method was found to be more sensitive and less costly, and the final results were obtained more quickly. Therefore, it could be applied to diagnose and monitor HCV infection in clinical practice.
