OBJECTIVE:
To evaluate and compare whole exome sequencing (WES) and targeted panel sequencing in the clinical molecular diagnosis of the Chinese families affected with inherited retinal dystrophies (IRDs).
METHODS:
The clinical information of 182 probands affected with IRDs was collected, including their family history and the ophthalmic examination results. Blood samples of all probands and their relatives were collected and genomic DNA was extracted by standard protocols. The first 91 cases were subjected to the WES and the other 91 cases were subjected to a specific hereditary eye disease enrichment panel (HEDEP) designed by us. All likely pathogenic and pathogenic variants in the candidate genes were determined by Sanger sequencing and co-segregation analyses were performed in available family members. Copy number variations (CNVs) detected by HEDEP were further validated by multiplex ligation-dependent probe amplification (MLPA). As PRGR ORF15 was difficult to capture by next generation sequencing (NGS), all the samples were subjected to Sanger sequencing for this region. All sequence changes identified by NGS were classified according to the American College of Medical Gene-tics and Genomics and the Association for Molecular Pathology (ACMG/AMP) variant interpretation guidelines. In this study, only variants identified as pathogenic or likely pathogenic were included, while those variants of uncertain significance, likely benign or benign were not included.
RESULTS:
In 91 cases with WES, pathogenic or likely pathogenic variants were determined in 30 cases, obtaining a detection rate of 33.00% (30/91); While in 91 cases with HEDEP sequencing, pathogenic or likely pathogenic variants were determined in 51 cases, achieving the diagnostic rate of 56.04% (51/91), and totally, the diagnostic rate was 44.51%. HEDEP had better sequencing coverage and read depth than WES, therefore HEDEP had higher detection rate. In addition, HEDEP could detect CNVs. In this study, we detected disease-causing variants in 29 distinct IRD-associated genes, USH2A, ABCA4 and RPGR were the three most common disease-causing genes, and the frequency of these genes in Chinese IRDs population was 11.54% (21/182), 6.59% (12/182) and 3.85% (7/182), respectively. We found 43 novel variants and 6 cases carried variants in RPGR ORF15.
CONCLUSION
NGS in conjunction with Sanger sequencing offers a reliable and effective approach for the genetic diagnosis of IRDs, and after evaluating the pros and cons of the two sequencing methods, we conclude that HEDEP should be used as a first-tier test for IRDs patients, WES can be used as a supplementary molecular diagnostic method due to its merit of detecting novel IRD-associated genes if HEDEP or other methods could not detect disease-causing va-riants in reported genes. In addition, our results enriched the mutational spectra of IRDs genes, and our methods paves the way of genetic counselling, family planning and up-coming gene-based therapies for these families.

Objective To observe the effect of acupuncture on cerebral glial fibrillary acidic protein(GFAP)expression of brain injury caused by intrauterine infection in neonatal rats.Methods Forty-three Wistar pregnant rats were divided into 2 groups:lipopolysaccharide(LPS)(n=35)and normal saline(n=8).Pregnant rats were consecutively injected intraperitoneally with LPS(450 ?g/kg)or saline on gestation 17 d and 18 d.LPS group were randomly divided into acupuncture group and model group.Acupuncture group were given acupunctured from 7 d to 21 d.GFAP expression was assayed with immunohistochemical technique.Results The number of GFAP immunoreaction(IR)strongly-positive neurons in the cerebral white matter was more in acupuncture group,less in model group and only very weakly IR-positive neurons were found in normal saline group.Conclusion Acupuncture can up-regulate the expression of GFAP in the cerebral white matter,which may contribute to the effect of acupuncture in improving brain injury caused by intrauterine infection.

Objective To study the characteristics of life events, coping styles and social supports in anxiety disorders patients. Methods 50 patients with generalized anxiety disorders (GAD), 44 patients with obsessivecompulsive disorders (OCD),23 patients with social anxiety disorders (SAD) and 99 healthy people were assessed by life event scale(LES),simplified coping style questionnaire(SCSQ) and social support rating scale (SSRS). Results Compared with healthy people, patients with GAD, OCD and SAD were all had higher scores of total life events (GAD 22.46±18.44;OCD 23.68±28.31;SAD 17.22±14.97;Healthy People 6.64±9.71)( F =14.216,P =0.000) and negative life events(GAD 18.76±17.99;OCD 20.02±24.98;SAD 12.00±13.16;Healthy People 4.56±7.51)( F =14.391,P =0.000).All patients were apt to choose positive styles less( F =16.505,P =0.000) and got less social supports totally ( F =26.506,P =0.000). The objective social supports( F =7.494,P =0.000)and subjective social supports ( F =26.985,P =0.000) were less and the utilization of social supports was lower ( F =13.931,P =0.000) in patients.Conclusions 1. Anxiety disorders patients often experience more or more serious life events, especially negative life events, are more likely to choose negative coping styles, and get less social supports. 2. Anxiety disorders may be related with people's characteristics of life events, coping styles and social supports.

Objective To explore the best opportunity of termination of pregnancy and conservative therapy in the treatment of lata trimester of pregnancy combining hypertension or preeclampsia.Methods The clinical data of 198 patients with pregnancy combining hypertension or preeclampsia were studied retrospectively.Among the total patients,107 patients performed conservative therapy (conservative therapy group),91 patients performed termination of pregnancy (termination of pregnancy group).The prognosis of two groups was compared,including maternal and neonatal complications and morbidity and mortality.ResultsThe cesarean section rate of conservative therapy group was 54.2% (58/107),termination of pregnancy group was 51.6%(47/91 ),there was no significant difference between two groups(P>0.05 ).The perinatal complication rate of conservative therapy group and termination of pregnancy group was 15.9%(17/107) and 17.6%( 16/91 ),there was no significant difference between two groups(P>0.05).The rate of placental abruption,low platelet disease,hypoproteinemia,postpartum hemorrhage between two groups had no significant difference (P>0.05).Conservative therapy group had 3 cases neonatal asphyxia,1 case neonatal death.Termination of pregnancy group had 7 cases neonatal asphyxia,1 case neonatal death.The rate of adverse events of conservative therapy group had no significant difference compared with termination of pregnancy group (P>0.05 ).The perinatal average weight of conservative therapy group was (2.635 ± 0.446)kg,termination of pregnancy group was (2.014 ±0.721) kg,there was significant difference (P<0.05).Conclusion Under the premise of control blood pressure,spasmolysis,ensure maternal and neonatal safety,expectant monitoring can give more chances for fetuses to get more mature so decrease the complications.
