Objective To evaluate the influence of anus-preserved procedures on life quality of patients with low rectal carcinoma.Methods One hundred and forth cases with low rectal carcinoma who underwent double stapling technique(DST) (n =64) or support binding procedure(SBP) (n =50) were selected as our subjects.Patients in both group were undergone total mesorectal excision (TME) to sever mesorectum.Anal Function was assessed by Xu Zhongfa Anal-Function's criterion after operation.All patients were performed a 5 years follow-up.Results The 5-years survival rate and local recurrence rate were 65.63％ (37/64),20.03％ (13/64) respectively in DST group,and 76.0％ (38/50),6.0％ (3/50) in SBP group.The differences were significant (P =0.049,0.032).The postoperative general occurrence rate of dysuria,dysporia and sexual disorder in the DST group were 31.25％ (20/64),17.19％ (11/64) and 45.31％ (29/64) respectively,higher than those of SBP group(14.00％ (7/50),4.00％ (2/50) and 26.00％ (13/50) ;P =0.037,0.045,0.034).Conclusion Both DST and SBP therapy are proved to be effective in terms of anus-preserved treatment for low rectal cacinoma.5-year survival rate is similar in the two groups,while the survival quality is better in SBP group than in DST group.

Objective To investigate the effects of silymarin on expressions of nuclear factor kappa B(NF-?B) and intercellular adhesion molecule-1(ICAM-1) in the kidneys of rats with unilateral ureteral obstruction(UUO)-induced renal fibrosis.Methods Seventy-two male Sprague-Dawley rats were randomly divided into 3 groups: sham-operated group(n=24),operated group(n=24) and silymarin treated group(n=24).Renal tubulointerstitial fibrosis model was established via UUO.Silymarin was given by gavage with 30 mg/(kg?d) in silymarin treated group,and the same volume normal saline was given by gavage in operated group and sham-operated group.In each group,8 rats were killed at 7,14 and 21 d after operation.Histological changes were observed in tubulointerstitial injury under microscope.The expressions of NF-?B and ICAM-1 in renal tissue were determined with immunohistochemical method.Results Tubuloin-terstitial injury scores in operated group at 7,14 and 21 d were 1.168?0.108,1.776?0.064 and 2.301?0.157,respectively,and Tubulointerstitial injury scores in the treated group at 7,14 and 21 d were 1.043?0.114,1.677?0.083 and 2.084?0.201,respectively.Tubulointerstitial injury scores in silymarin treated group were significantly lower than those in operated group(Pa

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.
