Background Congenital aniridia is a rare congenital autosomal dominant disease,which is shown as aniridia of double eyes,and the paired box gene 6 (Pax6) gene mutation is now known to be associated with congenital aniridia.Objective This study was to screen the Pax6 gene mutation in patients with congenital aniridia.Methods Eleven patients with congenital aniridia were enrolled in Tianjin Eye Hospital from August 2012 to October 2015,including 6 patients from 3 congenital aniridia family and 5 sporadic patients.All patients received routine ophthalmic examination.Peripheral venous blood of 3 ml was collected from the patients for DNA extraction according to the standard process of DNA isolation instructions,and all the exons of Pax6 gene,Elp4 gene,exon 5 ' and 3',intron splice sequence and SIMO sequence were amplified by PCR.Pax6 genes of the patients were sequenced using Sanger direct sequencing and multiplex ligation dependent probe amplification (MLPA) and compared with those of 500 ocular trauma patients.This study complied with Helsinki declaration,and written informed consent was obtained from each patient prior to any medical examination.Results Iris absence was found in all the patients,and the visions acuity was hand motion to 0.2.Lens dislocation was seen in 1 patient.Direct sequencing results found that three patients in AN-O1 family were c.688g＞t (p.E230X) mutation of Pax6 gene,and 3 of 5 sporadic patients carried c.468g＞a (p.W156X),c.613c＞t (p.Q205X) and c.141 +2t＞c mutant of Pax6 gene,and the c.688g＞t (pE230X) mutation was a novel-discovered mutation.No any mutation in Pax6,Elp4 gene and SIMO fragment was detected in 1 patient from AN-02 family,2 patients from AN-03 family and 2 sporadic patients by both direct sequencing and MLPA validation.No above-mentioned mutation was found in 500 normal individuals.Conclusions The mutation of Pax6 gene is a pathogenic mutation in congenital aniridia patients,and c.688g＞t (p.E230X) is a novel Pax6 mutant,which expanded the mutation spectrum of Pax6 gene.

Background Oculocutaneous albinism (OCA) is a hereditary disease of pigment absence in eyes,skin and hair due to the lack of congenital melanocyte.OCA is classified into 7 types based on different genetic mutations,and the mutation of tyrosinase (TYR) gene causes OCA type 1 (OCA1).OCA has obvious genetic heterogeneity and phenotypic heterogeneity.The molecular diagnosis of the mutant gene is helpful for the classification and molecular pathogenesis study of OCA.Objective This study was to screen the TYR mutation in OCA patients,and to analyze the association between the gene mutation type and clinical phenotype.Methods Ten patients with OCA were enrolled in Tianjin Ophthalmological Hospital from January 2011 to December 2014.The clinical and ocular manifestations of the patients were examined.Peripheral venous blood 3 ml was collected in the patients and their lineal relatives for the extraction of genomic DNA.Extracted DNA was amplified by PCR and the TYR gene sequence was analyzed,including all 5 exon coding sequence and exon 5 ' and 3' end and the non-coding region sequence of intron splicing in TYR gene.This study complied with Helsinki Declaration and the protocol was approved by Ethic Committee of Tianjin Eye Hospital.Informed consent was obtained from each subject.Results All the patients showed white or reddish hair and snow-white skin,and different degrees of pigment lack was seen in iris.The best corrected visual acuity of the patients was 0.05-0.2,and 3 patients complicated with nystagmus.Fundus findings showed a sunset-like change and dysplasia of macula.The TYR gene sequencing revealed that patient 1 was OCA1A subtype,with the compound heterozygous mutant of c.832C＞T (p.R278X) and c.1217C＞T (p.P406L),and his/her parents occurred the heterozygous mutation of exons P406L and R278X.The phenotype of the patient 1 was white hair and white iris.The patient 3 was OCA1B subtype,with the compound heterozygous mutations of c.1265G＞A (p.R422Q) and c.1217C＞T (p.P406L),showing an appearance of reddish brown hair and sallow iris.TYR gene mutant was not detected in other 8 patients.Conclusions The mutation of TYR gene is the main cause of OCA1 type.The phenotype of OCA1A subtype is no pigment in eyes and hair,and one of OCA1B subtype was obviously lessening of pigment.The difference of mutant genes of OCA is the cause of genetic and phenotypic heterogeneity.

The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.

Objective To investigate the clinical features of subarachnoid hemorrhagic moyamoya disease and the therapeutic effect of encephalo-duro-arterio-synangiosis (EDAS). Methods The clinical and imaging data of 38 patients with subarachnoid hemorrhagic moyamoya disease admitted to the Department of Neurosurgery,the 307th Hospital of PLA from January 2002 to April 2013 were analyzed retrospectively. Thirty-five patients underwent unilateral or bilateral EDAS (64-sides underwent EDAS,4 patients with aneurysms underwent endovascular embolization first),and 3 patients did not undergo any surgery. Results (1)Subarachnoid hemorrhagic moyamoya disease accounted for 10. 8%(38/353)of all the hemorrhagic moyamoya disease admitted in hospital over the same period,including 37 adults and 1 child. The male to female ratio was 1∶3. 22 (9/29),and the age of onset was 12 to 59 years. The mean age of patients was 39 ± 11 years. Four patients were combined with aneurysms. There were no significant differences in the distribution of Suzuki stage,anterior choroidal artery dilatation and posterior communicating artery dilatation in the remaining 34 patients without aneurysms between the bleeding sides and non-bleeding sides (P>0.05). (2 ) The patients were followed up for 13 -125 months (mean 51 ± 27 months ),two patients had rebleeding,one of them was intraventricular hemorrhage,the other was parenchymal hemorrhage. The postoperative modified Rankin score (mRS)was significantly lower in 35 patients whom were treated with EDAS. Compared with before surgery,there was significant difference (P<0. 05). The re-examination of positron emission tomography (PET)for 16 patients at 3 to 19 months after surgery showed that among the 23 surgically treated hemispheres,the cerebral metabolisms of 17 hemispheres were improved after surgery, and 6 did not have any change after surgery. The re-examination of whole brain digital subtraction angiography (DSA)at 5 to 30 months after surgery in 13 patients showed that revascularizations in 19 of 23 surgical hemispheres were effective. Conclusion Subarachnoid hemorrhagic moyamoya disease often occurs in adults,and women are more common. EDAS can achieve good revascularization effect and improve brain metabolism of patients,and thus relieve the symptoms of cerebral ischemia.

Objective To evaluate a method named “one-step procedure”,i.e.,combined duode-noscopy,laparoscopy and choledochoscopy for choledocholithiasis accompanied with cholecystolithiasis.Meth-ods Fifty-three cases with gallbladder stones combined with common bile duct stones diagnosed from February 2012 to February 2014 were assigned to two groups,29 cases in “one-step procedure”group,who underwent duodenoscopy,laparoscopy and choledochoscopy in one operation,and 24 cases in the control group,who first-ly underwent endoscopic sphincterotomy to remove common bile duct stones,and then LC was performed after several days.The rate of complications related to the procedure,success rate of complete stone removal,length of hospital stay and hospitalization expenses were compared between the two groups.Results All 53 patients underwent the surgery and ERCP procedure successfully.There were no significant differences between the“one-step procedure”group and the control group in complication rates[3.4%(1 /29)VS 12.5%(3 /24),P =0.21],complete stone removal rates[96.6%(28 /29)VS 100.0%(24/24),P =0.37].Differences were sig-nificant in length of hospital stay (6.7 ±1.3d VS 10.9 ±1.6d,P <0.01 )and hospitalization expenses (15 724 ±1 613 yuan VS 19 829 ±2 433 yuan,P <0.05)between the “one-step procedure”group and the control group.Conclusion The “one-step procedure”,the combined duodenoscopy,laparoscopy and chole-dochoscopy,is safe,effective,and has smaller length of hospital stay and lower hospitalization expenses.
