Background Congenital cataract is the major cause of blindness in children with plentiful clinical manifestations and closely linked with genetics. Objective Present study was to investigate the classification of congenital cataract in Yunnan province.Methods The manifestation characteristics of 184 eyes of 116 patients with congenital cataract in Yunnan province were analyzed.The relationship of performance of various types of congenital cataract between phenotype and hereditary feature were explored. Results All of the 116 congenital cataract eyes from 116 patients were divided into ten types based on the clinical appearance,including the complete cataract,nuclear cataract,posterior polar cataract,anterior polar cataract,coralliform cataract,coronary cataract,pulverulent cataracts,lamellar cataract and blue cataract.Bilateral nuclear cataract and unilateral entire cataract is most prevalent in these patients.Blue cataract and coralliform cataract belong to the less types.Forty-four in 116 cases were found to have the hereditary history and determined as autosomal dominant inheritance.Sporadic cases were determined in 72 cases.Conclusions The analysis of phenotype of the hereditary congenital cataract offers some clues to the classification of congenital cataract.
2.An Electroencephalogram-driven Personalized Affective Music Player System: Algorithms and Preliminary Implementation.
Journal of Biomedical Engineering 2016;33(1):38-41
In order to monitor the emotional state changes of audience on real-time and to adjust the music playlist, we proposed an algorithm framework of an electroencephalogram (EEG) driven personalized affective music recommendation system based on the portable dry electrode shown in this paper. We also further finished a preliminary implementation on the Android platform. We used a two-dimensional emotional model of arousal and valence as the reference, and mapped the EEG data and the corresponding seed songs to the emotional coordinate quadrant in order to establish the matching relationship. Then, Mel frequency cepstrum coefficients were applied to evaluate the similarity between the seed songs and the songs in music library. In the end, during the music playing state, we used the EEG data to identify the audience's emotional state, and played and adjusted the corresponding song playlist based on the established matching relationship.

Objective To analyse the clinical efficacy of methotrexate (MTX) combined with intrauterine embryo sac garrotte injection in the treatment of cesarean scar pregnancy (CSP), and discuss its clinical significance. Methods A total of 77 patients with CSP treated in our hospital during June 2013 to December 2016 were selected in this study. Forty patients treated with embryo sac destruction and methotrexate injection were included in the observation group, while 37 cases treated by uterine artery embolization combined with curettage were used as the control group. The time of vaginal bleeding, the time of postoperative blood level of human chorionic gonadotropin (HCG) returned to the normal level, average hospitalization cost and the curative rate were recorded in two groups. All patients were followed up by the outpatient visit. Results In the observation group, the vaginal bleeding time [(22.1±6.7) days vs. (29.5±10.8) days] and treatment cost [(8774.2 ± 714.5) yuan vs. (15258.3 ± 1084.2) yuan] were less than those of the control group (P<0.001). There were no significant differences in the recovery time of HCG [(26.4±9.0) days vs. (25.1±10.4) days] and treatment success rate (87.5%vs. 91.9%) between the two groups (P>0.05). No bleeding or threatened rupture of scar were found in two groups of patients. Conclusion In this study, we take the embryo sac puncture combined with methotrexate injection in the treatment of scar pregnancy. This method has the advantages of low operative difficulty, definite clinical curative effect and low cost

[Abstract ] Objective The purpose of this study was to construct a short hairpin RNA (shRNA) interference lentiviral vector targeting the humanβ-COP gene and to evaluate its inhibitory effect on β-COP in THP-1 cells. Methods We designed and synthesized 4 humanβ-COP-specific oligonucleotide sequences and inserted them into the pGMLV-SC1 vector to construct a recombinant vector fol-lowed by transfection of HEK 293T cells with the recombinant vector and Lenti-HG Mix to produce lentiviruses and detect the viral con-tent.After infecting the THP-1 cells with the packaged lentiviruses , we analyzed the inhibitory effect of β-COP-shRNA on the β-COP gene by quantitative PCR and Western blot . Results Sequencing confirmed that the β-COP-specific oligonucleotide sequences were in-serted into the lentiviral vector and the lentiviruses were packaged in the transfected HEK 293T cells, with the final viral content of 1 × 109 TU/mL.Quantitative PCR showed that the 4 β-COP-shRNA vectors significantly decreased the mRNA expression of β-COP (P<0.01), with interference rates of 16.9 %,32.5%, 74.0%, and 50.3%, respectively.Western blot also indicated their inhibitory effect on the protein expression of β-COP, with an inhibition rate of 76.4% onβ-COP-shRNA3. Conclusion Lentiviral shRNA interference vectors targeting human β-COP were constructed successfully , which could suppress the expression of the human β-COP gene.
