Current financing in disease control and prevention institutions in China / 上海预防医学

Objective To analyze the current situation of financing in disease control and prevention constitutions in China, to identify existing problems, to explore potential reasons, and to make policy recommendations accordingly. Methods Financial related indicators, including revenue and expense of disease control and prevention institutions, were collected through questionnaire survey. Moreover, some disease control and prevention institutions were selected for on-site survey. Results The proportion of public health institutions in the Total Health Expenditure had fallen from 7.0% in 2014 to 5.6% in 2018. The proportion of financial compensation in the operation of disease control and prevention institutions was less than 50%. The gap between revenue and expenditure had not been covered completely after the cancellation of three categories of administrative charges. In addition, financing mechanism of public health service funds remained unclear. Conclusion We recommend the strategies, including optimizing financing structure, increasing investment in disease control and prevention, increasing the level of financial guarantee, improving the mechanism of public health service funds, and multi-channel financing.

Progress in the studies on the role of antisense long chain noncoding RNA in tumor development / 中南大学学报(医学版)

Antisense long chain noncoding RNA (lncRNA) is a new class of RNA molecules. In recent years, antisense lncRNA has been found to play an important role in many life activities including tumorigenesis and development. It has become a hot topic in biological research in recent years. Because of the special structure, many antisense lncRNAs have specific expression in tumor tissues and are closely related to the clinical data of the patients. Thus, antisense lncRNA is a potential tumor molecular marker. Further functional studies have shown that lncRNA can participate in gene regulation by means of miRNA sponge and RBP binding to play an important role in tumor cell cycle, apoptosis, angiogenesis, invasion and metastasis. More studies on the mechanisms of antisense lncRNA in cancer are of great theoretical significance in understanding the etiology and pathogenesis of malignant tumors and RNA language. At the same time, antisense lncRNA is a molecular marker or a potential target for the early diagnosis of malignant tumors. The antisense lncRNA may have a broad clinical application prospect in the evaluation of therapeutic effect, prognosis and even gene therapy.

Clinical observation of vitamin B12 eye drops for vision fatigue caused by visual display terminals / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the clinical effect of vitamin B12 eye drops for vision fatigue caused by visual display terminals (VDT). METHODS: Totally 50 patients (100 eyes) with vision fatigue caused by VDT were averagely divided into two groups. The control group were treated with normal saline,the treatment group were treated with vitamin B12 eye drops, 3 times per day, one drop each time, continuous for 60d. Accommodative parameters and Schirmer Ⅰtest were measured and analyzed before and after treatment. RESULTS: After treatment, the results of Schirmer Ⅰtest, accommodative amplitude and accommodative facility of the treatment group were higher than those of the control group ( all P CONCLUSION: Vitamin B12 eye drops can lessen symptoms of dry eye, improve accommodative function and treat vision fatigue caused by VDT.

Assessment of personal noise exposure of overhead-traveling crane drivers in steel-rolling mills / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Noise is widespread occupational hazard in iron and steel industry. Overhead-traveling cranes are widely used in this industry, but few studies characterized the overhead-traveling crane drivers' noise exposure level so far. In this study, we assessed and characterized personal noise exposure levels of overhead-traveling crane drivers in two steel-rolling mills.</p><p><b>METHODS</b>One hundred and twenty-four overhead-traveling crane drivers, 76 in the cold steel-rolling mill and 48 in the hot steel-rolling mill, were enrolled in the study. Personal noise dosimeters (AIHUA Instruments Model AWA5610e, Hangzhou, China) were used to collect full-shift noise exposure data from all the participants. Crane drivers carried dosimeters with microphones placed near their collars during the work shifts. Work logs had been taken by the drivers simultaneously. Personal noise exposure data were divided into segments based on lines in which they worked. All statistical analyses were done using SPSS 13.0.</p><p><b>RESULTS</b>The average personal noise exposure (L(Aeq.8h)) of overhead-traveling crane drivers in the hot steel-rolling mills ((85.03 +/- 2.25) dB (A)) was higher than that in the cold one ((83.05 +/- 2.93) dB (A), P < 0.001). There were 17 overhead traveling cranes in the hot steel-rolling mill and 24 cranes in the cold one, of which carrying capacities varied from 15 tons to 100 tons. The average noise exposure level based on different lines in the hot and cold steel-rolling mills were (85.2 +/- 2.61) dB (A) and (83.3 +/- 3.10) dB (A) respectively (P = 0.001), which were similar to the average personal noise exposure in both mills. The noise exposure levels were different among different lines (P = 0.021).</p><p><b>CONCLUSION</b>Noise exposure levels, depending upon background noise levels and the noise levels on the ground, are inconstant. As the noise exposure levels are above the 85 dB (A) criteria, these drivers should be involved in the Hearing Conservation Program to protect their hearing.</p>

Measurement of personal noise exposure in a cold rolling mill / 中华预防医学杂志

<p><b>OBJECTIVE</b>To measure and evaluate the personal noise exposure of cold rolling mill workers by using noise dosimeter.</p><p><b>METHODS</b>According to job category and work type, all workers were divided into 11 groups. 3 to 5 day shift (8:00 to 16:00) workers from each group were selected as subjects for personal noise exposure measurement. SH-126 dosimeters were worn by each subject and collect noise data by a phone fix at collar. All subjects were asked to take notes about their working activities when they were wearing SH-126 dosimeters. Each worker's L(A)(eq) of 8 hours, geometric mean and range of each group were computed.</p><p><b>RESULTS</b>There were many noise sources in the workshop. Recorded data showed that noise exposure of cold rolling mill was unstable. The varieties of personal noise levels were quite large. Among 53 workers, the highest noise exposure level was 100.0 dB (A), the lowest was 81.2 dB (A); the highest work type was of the foreside welders [94.20 dB (A)], and the lowest was of the straight-cutters [89.02 dB (A)]; quality checkers had the biggest rang [16.3 dB (A)], and primary rolling workers had the lest [2.3 dB (A)].</p><p><b>CONCLUSION</b>Noise exposure of all the 11 groups were more than 85 dB (A). Noise protection of these workers should be improved. It suggested that measuring personal noise exposure individually with dosimeters might obtain the noise exposure level more integrally in the complicated environment.</p>
