Objective:To observe and analyze the pathogenic gene types and clinical phenotypes of Leber congenital amaurosis (LCA).Methods:A retrospective clinical study. Six patients with LCA confirmed by genetic testing and 18 family members were included in the study. The patients came from six unrelated families. The family was investigated with a specific hereditary eye disease enrichment panel which contained 463 known pathogenic genes and based on targeted exome capture technology first to indentify the potential pathogenic genes and mutations. Then the TULP1 , RPGRIP1 , GUCY2D pathogenic mutations were conformed by Sanger sequencing. The pathogenicity of the gene variation was searched through relevant databases and PubMed literature, and its function was explained by protein prediction software. Results:Of the 6 patients, 3 were males and 3 were females; the age was from 3 to 33 years. Nystagmus, finger pressing eyes, photophobia, and night blindness were seen in 5 cases; electroretinogram showed 3 cases of extinction or near extinction; and 4 cases of retinopathy. The results showed patients with compound heterozygous mutation of c.1318C> T and c.1142T> G, homozygous mutation ofc.1318C> T and compound heterozygous mutation of c.1153G> A and c.1561C> T of TULP1 in Family 1, Family 2 and Family 5, respectively. There were compound heterozygous mutations of RPGRIP1 c.391delG and c.1468-2A> G in Family 3 and c.715delA and c.1765C> T in Family 6, respectively. Homozygous mutation of c.3177_3178delAC of GUCY2D was found in Family 4.The parents of all six patients were carriers of corresponding heterozygous mutations. TULP1 gene c.1142T> G, RPGRIP1 gene c.391delG, c.715delA and c.1765C> T and GUCY2D gene c.3177_3178delAC mutations were novel mutations and unreported. The 381th amino acid locus of product protein of TULP1 gene was highly conserved among species. The protein prediction software predicted that the mutation pathogenic. The c.391delG, c.715delA and c.1765C> T mutations of RPGRIP1 gene and c.3177_3178delAC mutation of GUCY2D gene can lead to early translation termination of their product proteins, which are pathogenic variants. Conclusion:The pathogenic mutations of TULP1, RPGRIP1 and GUCY2D genes led to LCA 15, LCA 6 and LCA 1 in six families.

Swabbing samples were routinely collected from health care workers ( HCW) contacting newborns in Obstetrics Department of our hospital on every Wednesday during January to December 2015. Total 495 samples from nasal vestibule and 483 samples from hands of HCW were collected for bacterial culture.The carrying status of methicillin-resistant staphylococccus aureus ( MRSA) was analyzed.The results showed that the average carrying rate of MRSA in the nasal vestibule was 8.1%(40/495) and that in hands was 5.0(24/483)(χ2 =3.871, P<0.05).The MRSA detection rate of nasal vestibular samples in the second quarter was the highest [12.2%(17/139)], while that of hands samples was highest in the first quarter [ 15.3%( 15/98 ) ] . The study indicates that carrying rate of MRSA in health care workers contacting newborns of our hospital is high , and the training and monitoring should be strengthened among health workers to reduce the MRSA carrying rate .

Scatter coincident events are the important factor that affects the quality of positron emission tomography (PET) images. In this paper, according to the characters of projection data, a scatter correction method which uses maximum likelihood expectation maximization (MLEM) algorithm based on poisson model is proposed. We compared the sinograms and reconstructed images corrected by MLEM algorithm and deconvolution method respectively. The results indicate that the algorithm proposed in this paper increases the contrast of images while correcting scatter. It is better than the traditional method.

Objective To explore the effect of “double reinforcing and one unblocking” electroacupuncture on hepatic mitochondrial structure and ATPase activity in a rat model of senile yang deficiency. Methods Forty 5-month-old male SD rats were selected and randomly allocated to groups A, B, C and D, 10 rats each. Group A was a normal control group. A model of senile yang deficiency was made by 40 days’ subdermal injection of D-galactose and then 7 days’ intramuscular injection of hydrocortisone in the other three groups of rats. Group C received treatment with “double reinforcing and one unblocking”electroacupuncture at points Guangyuan(CV4), Zusanli(ST36) and Baihui(GV20); group D, treatment with electroacupuncture at points Zhongji(CV3), Yinlingquan(SP9) and Yintang(GV29). Treatment was given 6 times a week for a total of 4 weeks. After treatment, the anti-fatigue ability was determined by swimming exhaustion time, hepatic mitochondrial structure was observed under a transmission electron microscope and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities were measured by colorimetry in every group of rats. Results The mean swimming exhaustion time shortened significantly (all P＜0.01); hepatic mitochondrial inner and outer membranes were blurred, mitochondrial ridges deformed, ruptured or disappeared and mitochondria swelled; both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P＜0.01, P＜0.05) in groups B, C and D of rats compared with group A. Swimming exhaustion time lengthened significantly (P＜0.01), hepatic mitochondrial structure improved significantly and both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities increased significantly (P＜0.01, P＜0.05) in group C compared with group B. Rat mean swimming exhaustion time shortened (P＜0.05), hepatic rough endoplasmic reticula degranulated and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P＜0.05) in group D compared with group B. Conclusion “Double reinforcing and one unblocking”electroacupuncture can improve anti-fatigue ability, ameliorate hepatic mitochondrial ultrastructure, increase hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities and promote hepatic energy metabolism in a rat model of senile yang deficiency.
