Objectives To detect genetic causes of dystrophic epidermolysis bullosa (DEB). Methods Next-generation sequencing was used to detect a neonate with DEB. Sanger sequencing was used to confirm the results and detect his parents and grandmother on his mother side from the family. Results The neonate was found to have heterozygous mutation c.6781C>T of exon 86 in COL7A1 gene.This mutation results in R2261X nonsense mutation in typeⅦcollagen. His mother and grand-mother on his mother side have the same mutation. Conclusion Next-generation sequencing technology is a useful tool for the detection of mutations of COL7A1 gene, which is valuable for clinical application.

Objective To explore the clinical and biological characteristics and treatment effect of acute myeloid leukemia (AML) in elderly patients. Methods The clinical data of 62 patients over 60 years old with AML were retrospectively analyzed, and they were compared with those of 60 younger adult patients (18-59 years old) at the same period. Results In elderly patients, the complete remission (CR) rate was 27. 7% and the overall effective rate was 44.7%, which were lower than those of younger adult patients (74.1% and 87.9 %, 1-espectively, P＜0.01). The early death rate was 19.0% and the mortality rate during the first two induction chemotherapy was 29. 3% in the elderly, which were higher than those of younger adult patients (3. 3% and 6.7%, 1-espectively,P＜0.01). The 27.4% of elderly patients were diagnosed as myelodysplastic syndrome (MDS)-transformed AML, which were more than that of younger adult patients (10.0%, P＜0.05), and they had lower CR rate than those without MDS (P＜0. 05). The 28.2% of elderly patients had lymphoid antigen positive AML and 71.8% of patients showed CD34+ which were higher than those of younger adult patients (8. 1% and 48.6%, respectively, P＜0. 05), and they had lower CR rate than those of lymphoid antigen negative and those of CD34- AML (P＜0. 05). Elderly patients had less favorable and more unfavorable karyotypes than younger adult patients (45.7 % and 15.4 %, P＜0. 05). Conclusions The elderly patients with AML have more unfavorable prognostic factors than younger adult patients. They have lower CR rate and higher mortality rate. There are many specialties in elderly patients and the treatment strategy should be made more individually.

ObjectiveTo explore the application effect of using the comprehensive index method for occupational health risk assessment in the lead-acid battery enterprises. Methods Convenient sampling method was used to select two lead-acid battery enterprises A and B in Jiangsu Province, with eight key positions including ball grinding, plate casting, pasting, plate coating, plate grinding, plate slicing and brushing, welding and acid charging as the research subjects. Worksite survey of occupational health was conducted in these two lead enterprises, and the levels of lead smoke, lead dust and sulfuric acid in the key positions were detected. The health risk of occupational hazards in the eight key positions was evaluated by a comprehensive index method. Results The time-weighted average concentration (C_TWA) of lead smoke in plate casting and welding positions of enterprise A, the C_TWA of lead dust in plate grinding and plate slicing and brushing positions of enterprise A, the C_TWA of lead dust in plate grinding position of enterprise B, the C_TWA of lead smoke in welding position of enterprise B were exceeded national occupational exposure limits. The risk assessment results of the plate casting, welding, plate grinding and plate slicing and brushing positions were moderate risk, while other positions were low risk in enterprise A. The risk assessment results of the plate grinding and welding positions were moderate risk, while other positions were low risk in enterprise B. Conclusion The results of risk assessment by the comprehensive index method were consistent with the results of occupational hazard factors detection. The comprehensive index method could well evaluate the occupational health risks of lead-acid battery enterprises.

Objective:To identify and to analyze occupational exposure factors generating from production process in an enterprise processing waste electronic products, to provide scientific evidences for protection measures.Methods:From June to October 2017, seven waste electrical and electronic product processing enterprises in a province were selected as the research objects. These seven enterprises all include refrigerator dismantling line, washing machine dismantling line, air conditioning dismantling line, TV/computer dismantling line, CRT cutting line. Some enterprises also have circuit board line, wet precious metal recycling line, plastic crushing line, plastic granulating line and other deep processing operations such as precious metal recycling of waste circuit board, waste plastic crushing and recycling. The data were collected by the methods of occupational health field investigation and occupational health testing, and the exposure level of occupational hazard factors was evaluated by combining the effect of the protective facilities of occupational health engineering.Results:the main occupational hazard factors of waste electrical and electronic products treatment enterprises were dust, noise, heavy metal, flame retardant, mercury, fluoride, cyanide, sodium hydroxide, hydrochloric acid and nitric acid. 145 effective samples were obtained from heavy metal sampling, including 102 individual samples and 43 fixed-point long-term samples. Among them, 8 samples lead exceeded the standard, all occurred in the TV dismantling line. In addition to flame retardants, plasticizers, insecticides and other components can be detected by high-throughput qualitative analysis using liquid chromatography-time-of-flight mass spectrometry. Finally, 123 effective 8-h equivalent sound level values were obtained by individual noise detection, 86 of which exceeded the standard, with a rate of 69.9%.Conclusion:there are potential occupational hazards in the process of dismantling waste electrical and electronic products.

Objective To study the clinical curative effect of syndrome differentiation-based treatment with traditional Chinese medicine on patient with Chronic Kidney Disease (CKD3-4). Method According to prospective multicenter randomized controlled study which was applied to the patients with CKD3-4 , the total of 339 patients were divided into two groups. To one group as standard including 167 patients ,the other including 172 patients. Chinese Traditional Patent Medicine single or combined-prescription oral treatment according to syndrome differentiation-based treatment was employed. To the other group as reference , Chinese Traditional Patent Medicine oral treatment according to experienced rule was applied. The clinical curative effect results were obtained after a 24 weeks-treatment. Result The Scr ,eGFR and UTP with CKD3 in standard group illustrate statistics significance (P<0.05). On the opposite, those of the reference group remain insignificance (P > 0.05). The clinical curative effect result of patient in standard group was better than that of reference group. About the clinical curative effect of CKD4, no statistics significance difference (P > 0.05) could be found between groups or between patients in one group. The TCM score of patient with CKD3-4 in standard group have improved (P < 0.05) according to baseline. However, that of reference group did not show any statistics significance (P > 0.05). Conclusion Syndrome differentiation-based treatment with traditional Chinese medicine illustrated a better result in protection of renal function, reduction in urinary protein and decline in TCM score than the treatment according to experienced rule.

The spike gene of porcine epidemic diarrhea virus (PEDV) was sequenced from 55 South China field strains isolated from pigs with symptoms of diarrhea. The sequences were compared within the set of field strains as well as with reference strains available in GenBank. Within the 55 South China PEDV field strains, the deduced amino acid sequence identities ranged from 93.8% to 99.9 % and ranged from 90.7% to 99.5% when compared with the foreign reference strains in GenBank. Our phylogenetic analysis showed that 10 of the 55 South China PEDV strains belonged to G1b and 45 belonged to G2b.
