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 compare the 96-week efficacy of de novo combination therapy with lamivudine ( LAM ) and adefovir dipivoxil (ADV) to that of optimization monotherapy for chronic hepatitis B (CHB).Methods A total of 155 CHB patients were collected from the First Affiliated Hospital of Anhui Medical University during 2007 and 2009.All patients were randomly assigned to LAM monotherapy group ( n =53 ),ADV monotherapy group ( n =50 ) or LAM with ADV combination group ( n =52 ) according to randomized digital table.The liver and kidney functions,HBV serum markers,and HBV DNA loads were tested every 24 weeks.If patients in LAM or ADV group had poor response or virological breakthrough,they were given optimized therapy with ADV or LAM at week 24,48 or 72.One-way ANOVA (normal distribution and homoscedasticity ) and non-parametric test (non-normal distribution ) were performed to compare measurement data among groups.The impact factors of early virological response were analyzed by binary Logistic regression method.Results At week 24,the complete virological responses in LAM group,ADV group,and LAM + ADV group were 66.0% ( 35/53 ),34.0% ( 17/50 ) and 90.4% ( 47/52 ),respectively (x2 =35.282,P < 0.01 ) ; while,at week 96 the complete virological responses in three groups were96.2% (51/53),86.0% (43/50) and 100.0% (52/52),respectively (x2 =19.115,P>0.05).At week 96,the cumulative recover rates of ALT in LAM group,ADV group,and LAM + ADV group were 86.8% (46/53),82.0% (41/50)and 94.2% (49/52),respectively (x2 =3.613,P >0.05);however,the ALT levels in three groups were statistically different (x2 =11.195,P < 0.01 ).At week 96,the HBeAg seroconversion rates in LAM group,ADV group,and LAM + ADV group were 31.3% ( 10/32),20.7% ( 6/29 ) and 38.7% ( 12/31 ),respectively (x2 =2.313,P > 0.05 ).Early virological response was not found in I patient in LAM group and 19 patients in ADV group; virological breakthrough occurred in 11 patients in LAM group and 1 patient in ADV group.All patients in LAM + ADV group had early virological responses and had no virological breakthrough.Logistic regression showed that complete virological response at week 24 was correlated with the baseline HBeAg,the initial treatment and HBV DNA load.Layered evaluation showed that there were significant differences in early complete virological responses among three groups for patients with positive HBeAg,HBV DNA > 6.28 × 106 copies/mL and ALT ≤5 ×ULN (x2 =7.726,10.921 and6.100,P<0.05 or <0.01) ; for those with HBV DNA >6.28 × 106copies/mL,complete virological response was not observed in ADV group treated for 24 weeks.Conclusion LAM combined with ADV has stronger antiviral activity,lower resistance rate and can improve liver function and virological response,especially for the patients with HBeAg-positive,high HBV DNA loads and ALT ≤5 × ULN.
