Objective To develop a phenylketonuria (PKU) screening method based on a compact disk (CD) type microfluidic chip capable of generating reciprocating flow within the microchannels that facilitate rapid DNA hybridization. Methods This microfluidic device consists of a two-layer structure: a polydimethylsiloxane (PDMS) top layer containing 12 DNA hybridization microchannels, and a bottom glass layer with immobilized hydrogel conjugated DNA arrays. The DNA arrays included R243Q, V245V and the blank control probes. When the CD device was spun, the PCR products were driven into the hybridization channel by centrifugal force. When the rotation of the CD device was stopped, capillary force pulled the PCR products solution to flow back to the channel. After the on-chip hybridization, the hybridization signals were captured on a fluorescence microscope. The specificity, detection limitation and reproducibility of this device were evaluated. Thirty DNA samples from pregnant women with suspected PKU were detected by this device.Then the results were compared with DNA sequencing results. Results With the compact disk type microfluidic chip, the hybridization time could be reduced to 15 min, sample consume could be as low as 1. 5 μl and the detection limitation was 0. 7 ng/μl. With the chip based method, samples of PKU patients and healthy controls were detected and the results were consistent with DNA sequencing results. Five different batches of chips and five micro-channels of each chip were selected to test one PKU patients with V245V mutation. All the results were positive, indicating good reproducibility. Four cases of V245V mutation and 1 case of R243Q mutation were found in 30 suspected PKU carried pregnant women. Conclusion The compact disk microfluidic device has advantages of simple, rapid and highly sensitive, thus is well suited to PKU screening.

Objective:To investigate the effect and molecular mechanism of long non-coding RNA (Linc01278) on the proliferation, invasion and migration, and tumor phenotype of prostate cancer cells.Methods:Prostate cancer tissues and corresponding normal tissues adjacent to the cancer were obtained in 46 patients with prostate cancer confirmed by the hospital from Dec. 2018 to Dec. 2019. Real-time fluorescence quantitative PCR (qPCR) was used to detect the expression levels of Linc01278 and miR-145 in prostate cancer tissues and adjacent normal tissues. The prostate cancer PC-3 cells were transfected with plasmids and cells were divided into four groups: blank group, control group, overexpression group and rescue group. The blank group was not given any treatment; the control group was transfected with blank control vector and miRNA Control; the overexpression group was transfected with Linc01278 overexpression vector and miRNA Control; the rescue group was transfected with Linc01278 overexpression vector and miR-145 mimics. Bioinformatics analysis was used to predict the binding site of Linc01278 to miR-145. Dual Luciferase Reporter Gene Assay was used to analyze the adsorption of Linc01278 on miR-145; Transwell experiment was used to detect the invasion and migration ability of the four groups of cells; CCK-8 method was used to detect the cell proliferation ability of the four groups of cells. Western blot was used to detect the expression of OCT4 and SOX2 in the four groups of cells; qPCR was used to detect the expression of OCT4, SOX2 and miR-145 in the four groups of cells.Results:Compared with adjacent normal tissues, Linc01278 was significantly higher in prostate cancer tissues (adjacent normal tissues: 0.012±0.002 vs prostate cancer tissues: 0.022±0.002, P=0.0072) , while miR-145 was significantly lower (adjacent normal tissues: 0.117±0.011 vs prostate cancer tissues: 0.081±0.007, P=0.0005) . Correlation of both was negative significantly ( P=0.0012) . Targetscan analysis revealed that the 804-825 position of the Linc01278 transcript had a complementary base pairing with miR-145. The results of the double luciferase reporter gene showed that miR-145 mimics could significantly reduce the luciferase activity of Linc01278 ( P<0.01) . Compared with the blank group and the control group, the invasion and migration cells, the relative proliferation ability, the expression of Oct4 and Sox2 mRNA and protein were significantly increased, and the expression of miR-145 was significantly decreased in the overexpression group ( P<0.05) . While compared with the overexpression group, the invasion and migration cells, the relative proliferation ability, Oct4 and Sox2 were significantly decreased in the rescue group, and the expression of miR-145 was significantly increased ( P<0.01) . Conclusion:Linc01278 may promote the proliferation, invasion and migration of prostate cancer cells by specifically adsorbing miR-145.

Objective:To evaluate the life quality of patients with Kashin-Beck disease (KBD), and to analyze its influencing factors.Methods:From September 2017 to May 2019, adult KBD patients aged 18 years old and over were selected as the study subjects in the historical serious disease areas (Yongshou County and Linyou County) of KBD in Shaanxi Province. KBD patients were investigated by using the basic information questionnaire and the Chinese version of the European Five-dimensional Five-level Health Scale (EQ-5D-5L), the distribution of health status in the five dimensions of mobility, self-care ability, daily activity, pain/discomfort, and anxiety/depression were described, and each dimension included five levels of no problem, mild problem, moderate problem, severe problem, and extreme problem. EQ index (- 0.391 - 1.000) was used to evaluate the quality of life of patients based on group perspective, the higher EQ index was, the better life quality of the group would be; visual analogue system (VAS) score (0 - 100 points) was used to evaluate the life quality of patients based on individual perspective, the higher VAS score was, the better life quality of the individual would be. At the same time, multiple linear regression analysis was used to analyze the life quality of KBD patients.Results:A total of 245 KBD patients were included, aged (60.37 ± 7.10) years old. The mild problems of self-care ability and anxiety/depression of KBD patients, accounted for the largest proportion, which were 31.8% (78/245) and 27.3% (67/245), respectively; in terms of daily activity, the moderate problem accounted for the largest proportion, which was 32.7% (80/245); in terms of mobility and pain/discomfort, the severe problem accounted for the largest proportion, which were 46.9% (115/245) and 45.7% (112/245), respectively. EQ index [median (quartile range)] was 0.311 (0.059, 0.563), and VAS score was 42.5 (30.0, 60.0) points. After multiple linear regression analysis, the effects of education level, pain level, body deformity inferiority complex, and social participation barrier on EQ index were statistically significant ( P < 0.01); the effects of economic level, pain level, body deformity inferiority complex, and social participation barrier on VAS score were statistically significant ( P < 0.05). Conclusion:The life quality of KBD patients is poor, it is affected by physical, psychological and social aspects, so relevant medical workers should pay attention to the overall health of KBD patients.
