Objective To investigate the association between MPO gene single nucleotide polymorphisms (SNP) loci (rs2333227,-643G/A) and clinical characteristics in Kawasaki disease (KD) in Han population in central China. Methods A case-control study was performed. Two hundred and thirty-seven children with KD and 249 normal children were recruited. The polymorphism distribution of SNP was detected using PCR-RFLP. The clinical data of children with KD were collected. Results The frequency of SNP loci (rs2333227) genotypes (GG, GA, AA) was signiifcantly different between children with KD and normal children (P=0.039), the allele frequency was also signiifcantly different between two groups (P=0.012), and the G allele was the risk factor. Compared with other genotypes, KD children with GG genotype had higher frequency in hand-foot edema (P=0.029). The SNP polymorphism was also associated with peritoneal effusion (P=0.028), however this SNP polymorphism was not associated with conjunctival hyperemia, oral mucosa lesions, and coronary artery lesion (P>0.05), also was not associated to imaging characteristics of hepatomegaly, splenomegaly, and lobular pneumonia (P>0.05). Conclusion The SNP loci (rs2333227) in MPO gene was associated with KD susceptibility, the G allele was a risk factor, and the SNP polymorphisms is associated with some clinical characteristic.

Objective To explore the clinical features of Marfan syndrome (MFS) and its virulence gene mutation of FBN1.Methods Clinical data of 2 children with MFS were retrospectively analyzed, and pertinent literatures were reviewed. Results Case one was a 1 year and 10 months old boy with a special face, bilateral lower eyelid edema, high palatal arch, slender fingers and toes. A little of moist rales in lung could be heard, and systolic accentuated in apex could be heard too. Echocardiography showed that aortic coronary sinus dilated, aorta and pulmonary artery broadened, left ventricular diverticulum, a small amount of mitral regurgitation,and moderate tricuspid regurgitation. Electrocardiogram showed incomplete right bundle branch block. Gene detection found a c.3037G>A mutation (p.Gly1013Arg) inFBN1. Case two was a 12 years old slender boy with spider-like ifnger/toe, high myopia, 2/6 systolic and diastolic murmur in the ifrst and two auscultation area in aortic valves. Echocardiography showed the aortic sinus signiifcantly broadened, aortic incompetence, mild pulmonary regurgitation and left ventricular enlargement. Gene detection found heterozygous mutation of c.1876G>A (p.Gly626Arg) in FBN1, which has not been reported.Conclusion The diagnosis of MFS can be conifrmed byFBN1 gene detection. A new mutation of c.1876G>A (p.Gly626Arg) was detected.

AIM:To establish an HPLC fingerprint spectrum of Red Peony Root ( Radix paeonia rubra). METHODS:Ten batches of samples were extracted by 50% ethanol and extract liquor was evaporated to dryness,resolved with methanol. The HPLC analysis was performed on a Diamonsil C18 column with the eluting system of gradient acetonitrile and water. MS was applied to the determination of possible chemical structure. RESULTS:Nine main characteristic peaks were selected from the fingerprint spectrum of 10 batches of samples. Five constituents of which were identified as gallic acid,peoniflorin albiflorin,benzoylpaeoniflorin and paeonol based on the MS spectra. CONCLUSION:The method is valuable for quality conthol of Red Peony Root.

ObjectiveTo investigate the association between nucleotide polymorphisms ofGRIN3A gene and clinical characteristic of Kawasaki disease (KD) in children in Han population in central Chinese.MethodsA case-control study was performed. A total of 191 children with KD were recruited and 217 healthy children were served as controls. The distribution of SNP was determined by PCR-RFLP. Arterial lesions were detected by echocardiographic.ResultsThe distribution of three genotypes (CC, CG, GG) in SNP (rs7849782) was statistically difference between KD and control groups (P=0.034), and C allele was associated with KD susceptibility (OR=1.46, 95%CI: 1.10-1.92,P=0.007). In children with KD, the polymorphism of SNP loci was signiifcantly associated with oral mucosa lesions and coronary artery lesion (P<0.05), but not associated with conjuncti-val hyperemia, hand-foot edema, rash, and lymphadenopathy (P>0.05). The polymorphism of SNP loci was also associated with the levels of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) (P<0.05).ConclusionThe ploymorphism of SNP loci ofGRIN3A gene (rs7849782) was associated with the susceptibility of KD. The C allele was the risk factors. The poly-morphism of SNP was associated with oral mucosa lesions and coronary artery lesion, and may affect the levels of ESR and CRP.

Objective To comparative analyze the influence factors of short-term (6 months) and long-term (10 years) prognosis in patients with HBV-related acute-on-chronic liver failure (ACLF),and to provide some reference values on clinic therapy and follow-up management.Methods The data of 524 hospitalized patients with ACLF from January 2001 to December 2009 were analyzed retrospectively.The follow-up termination time was December 2013.Patients were all given internal medical therapy,and were given antiviral therapy with nucleoside and nucleotide analogs (NAs) (yes/no) and plasma exchange in artificial liver support system (yes/no) according to the patient's informed choice.The method of Cox regression analysis was used to analyze the short-term prognostic factors and long-term prognosis factors of ACLF.Results The short-term prognosis factors in patients with ACLF were MELD scores,ages,percentage of neutrophils,hepatic encephalopathy,whether to apply NAs or not,HBV DNA levels,times of plasma exchange in artificial liver support system,cholinesterase levels and total bilirubin levels in turn (P <0.05).The long-term prognosis factors were ages,whether to apply NAs or not,MELD scores,cholinesterase levels,concomitant infection,white blood cell counts,gender and hepatic encephalopathy in turn (P < 0.05),and antiviral therapy with NAs was a time-dependent independent prognostic factor.Conclusions There are some differences between the short-term prognosis factors and the long-term prognosis factors in patients with ACLF.We should give antiviral therapy with NAs,measures to improve liver function,preventions and treatments of infection and hepatic encephalopathy and other complications from early-stage to long-term follow-up managements.And in early-stage of ACLF we should also give the treatment with artificial liver support system.
