ABSTRACT
Psoriasis-2 (PSORS2) is caused by the heterozygous mutation of the caspase recruitment domain 14 (CARD14) gene on chromosome 17q25. To evaluate the contribution of CARD14 variants in psoriasis of the Chinese Han population, we performed deep sequencing of the CARD14 gene in 372 Chinese Han patients with psoriasis. The exonic nucleotide variants were confirmed by Sanger sequencing in the affected individuals and 1114 controls. In 27 patients with psoriasis, we identified 15 variations, including three novel variants: c.381C[G (p.Cys127Trp), c.712A[G (p.Met238Val) and c.2260_2261delinsGG (p.Gln754Gly). These findings could enrich and update the Human Gene Mutation Database of CARD14 variants for psoriasis.
ABSTRACT
Objective To investigate the correlation between urinary 8-iso-prostaglandin F2α (8-iso-PGF2α) level and carotid atherosclerotic plaque stability in patients with acute ischemic stroke.Methods The patients with acute ischemic stroke were enrolled consecutively.According to the findings of carotid artery ultrasound,they were divided into either a non-plaque group or a plaque group,and then the plaque group was redivided into a stable plaque subgroup and an unstable plaque subgroup.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of urinary 8-iso-PGF2α.Multivariate logistic regression analysis and Spearman correlation analysis were used to investigate the relationship between 8-iso-PGF2α and carotid artery plaques.Results A total of 150 patients with acute ischemic stroke were enrolled,including 104 had carotid artery plaque (30 were stable plaques and 74 were unstable plaques) and 46 had no carotid artery plaque.The urinary 8-iso-PGF2α level (86.45 ± 6.20 ng/mmol creatinine vs.45.70 ±6.19 ng/mmol creatinine; t =37.136,P=0.001) and intima-media thickness (IMT) (2.89 ± 1.03 mm vs.0.86 ±0.53 mm; t =3.518,P =0.002) in the plaque group were significantly higher than those in the nonplaque group.Multivariate logistic regression analysis showed that urinary 8-iso-PGF2α level (odds ratio [OR] 1.183,95％ confidence interval [CI] 1.087-1.276; P=0.001) and IMT (OR 28.642,95％ CI 8.276-137.231; P =0.001) were the independent risk factors for carotid artery plaque.Pearson correlation analysis showed that there was no significant correlation between urinary 8-iso-PGF2α level and carotid artery IMT (r =0.075,P =0.264).The urinary 8-iso-PGF2α level of the unstable plaque subgroup was significantly higher than that of the stable plaque subgroup (97.30 ± 7.20 ng/mmol creatinine vs.69.17 ±9.25 ng/mmol creatinine; t =16.506,P =0.001).Multivariate logistic regression analysis showed that urinary 8-iso-PGF2α level (OR 4.652,95％ CI 1.732-12.643; P =0.001) was an independent risk factor for unstable plaque.Conelusions The urinary 8-iso-PGF2α level is associated with the existence of carotid atherosclerotie plaque and instability,its increased level is an independent risk factor for carotid plaque instability in patients with ischemic stroke.

Objective To investigate the clinical guiding significance of lymphoscintigraphy with 99mTc-DX for radical lateral lymph node dissection with pelvic autonomic nerve preservation(PANP) in lower rectal cancer.Methods In 67 patients with pathologically proven lower rectal cancer,37MBq/0.8ml 99mTc-DX was injected into submucosa of the rectum through rectal endoscopy.At 0.5h,1h,2h,3h,4h,6h,12h,and 24h after the injection,the patients underwent pelvic and lower abdominal lymphoscintigraphy. The operative method was determined according to the imaging results,and the results of lymphoscintigrams were correlated with postoperative lateral node histologic examination.Results The scintigrams were postive in 37 cases,and all were unilateral.The positive patients underwent PANP.The image results were compared with histological lymph node examination in all patients operated upon for rectal cancer.Histologically,the cases in conformity were 26(70.3 %),false positive in 11 cases(29.7 %),and 2 of 30 false positive patients who demonstrated metastases to lateral node were operated by PANP,while the others underwent only PANP(type Ⅰ) without lateral lymph nodes dissection.The percentage of good sexual function of the two groups of cases after operation was 74.4 % and 71.4 % respentively.The percentages of mild dysuria and good function of urination were both 100 %.Conclusions Lymphoscintigraphy with 99mTC-DX has particular guiding significance in selection of PANP for lower rectal cancer.
ABSTRACT
AIM: To explore the influence of processing with fresh-scorpion on element contents in crude scorpion in order to elucidate the processing method. METHODS: Macro-elements Ca,Mg and trace-elements Fe,Cu,Zn and Pb in crude scorpion were determined with emission spectrometric method. RESULTS: Contents of Ca,Mg in live-scorpion group were obviously lower than that in commercial-scorpion(P0.05). CONCLUSION: Processing with live-scorpion has obviously advantage over one with commercial scorpion on element contents.
