Objective To observe the efficacy of pulsed dual-wavelength 595 and 1064 nm laser in treating ulcerated infantile hemangioma.Methods Lesions from 40 patients were treated with the laser.The distribution of lesion sites was in buttuck and perianal area (13 patients),vulvar lips (7),groin and inside thigh (5),scrotum (4),neck (3),scalp (2),lip (2),trunk and limbs (4).All lesions including ulcer and non-ulcer were conducted with 595 nm plused dye leaser at the first therapy.Later,595 nm pulsed dye leaser was continued or performed with Group 1 or Group 2 parameter of 595 and 1064 nm multiplex mode until the treatment was finished according to the thickness of the lesion.The frequency of treatment was one to six times.The interval of the treatment was four weeks.Results The ulcer from 39 lesions healed gradually in 1 to 2 weeks (average 9.5 days) after the first treatment.These ulcer lesions were healed four weeks after the first time of therapy.The recovery rate of ulcerated lesion was 97.5 ％.For the whole lesion,after 1 to 6 treatments,13 lesions showed excellent result,19 lesions showed good result,and the effective rate was 80 ％.Pain relieved 2 to 7days (average 3.5 days) after the first laser therapy in 35 patients who accompanied with pain.Pain score decreased from 1.875 to 0.125 before and after treatment,with significant difference(P＜0.05).The tolerance of the treatment was good and no side effect was observed.Conclusions 595and 1064 nm dual-wavelength laser is a safe and effective tool for treating ulcerated infantile hemangioma.

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 review the characteristics changes of calcium phosphate cement (CPC) as drug delayed release carrier before and after carrying different drugs, analyze dynamic principle and influential factors of drug delayed release system, and summarize new advances of CPC in animal experiments and clinical studies.DATA SOURCES: A computer-based online search of CNKI (www.cnki.net/index.htm) and PubMed (http://www.ncbi.nlm.nih.gov/PubMed) was performed for articles published between 1985 and 2009 with the key words of "calcium phosphate cement, CPC, drug delivery system, release" in Chinese and English.DATA SELECTION: Articles highly related with CPC; articles concerning CPC as drug delivery system. Repetitive articles were excluded.MAIN OUTCOME MEASURES: Changes in physico-chemical properties and drug release dynamics of CPC as delivery carrier of different drugs.RESULTS: CPC is an outstanding skeletal defect restorative material. Considering physico-chemical properties, drug release dynamics and histocompatibility, CPC is good delayed release carrier of drugs. However, its clinical application is limited only in bone defect repair of unloading sites due to its bad compressive strength and adhesivity. Therefore, studies on these aspects require exploration.CONCLUSION: CPC as a drug delivery system is a novel administration method. It can repair bone defect and release drug to achieve favorable treatment effects. CPC has been extensively used in osteomyelitis, bone tuberculosis, bone tumor, bone fracture, bone nonunion, and artificial joint replacement.

Objective To investigate the clinical significance and effect of total hip arthroplasty (THA) in treatment of bony ankylosis of the hip in patients with ankylosing spondylitis (AS).Methods The study enrolled 23 patients (35 hips) undergone THA for bony ankylosis of the hip in AS between March 2008 and November 2012.Postoperative outcome was measured based on Harris hip score and Xray images.Results Preoperative Harris hip score of (27.6 ± 2.3) points increased to (86.7 ± 2.6)points postoperatively.Hip flexion and adduction deformity presented correction postoperatively.Total hip range of motion (flexion,adduction,abduction,and external rotation) improved from (45.7 ±5.3) o preoperatively to (206.9-±4.7) °postoperatively and mean hip flexion activity was 81 °.Hip activity achieved significant improvement and pain was relieved.X-ray films revealed proper position of prostheses without the presence of loosening or subsidence.Two patients (3 hips) experienced mild pain after a long period of walking.Four patients had heterotypic ossification including Brooker grade Ⅱ in one patient and Brooker grade Ⅰ in three.Conclusion THA is an effective treatment for bony ankylosis of the hip in AS,for it rebuilds joint function,relieves pain of the hip and improves patients' quality of life.
