[Research of classical prescription based on QbD concept:optimization of extraction process for modified Siwu Decoction].

As an advanced concept in international pharmaceutical research,quality by design( QbD) can fulfill the strategic requirements of drug quality from testing to design. In this paper,the extraction process of Yanggong Prescription which was the modified Siwu Decoction was optimized based on QbD concept. With the extraction amount of solid matter,the content of ferulic acid and the content of paeoniflorin as critical quality attributes( CQAs),the failure mode and effect analysis( FMEA) was used to screen potential critical process parameters( p CPPs).

[Adsorption of Pb and Cd from Aqueous Solution Using Vermicompost Derived from Cow Manure and Its Biochar].

Using vermicompost (CV) as raw material, its biochar (CVC350) was prepared at 350℃ and then their physio-biochemical properties were characterized. Furthermore, adsorption studies were performed in a batch system for removing Pb and Cd ions from solution. The characterization results revealed much higher surface area, smaller pore size, greater aromaticity and nonpolarity of CVC350 as compared to CV.

A single-nucleotide polymorphism of the TNFAIP3 gene is associated with systemic lupus erythematosus in Chinese Han population.

Systemic lupus erythematosus (SLE) is a complex systemic disease influenced by genetic and environmental factors. The exact pathogenesis of SLE is still unknown. Recently, several genome-wide association studies (GWA) in European population have found many novel susceptibility genes for SLE including TNFAIP3.

A novel KIT missense mutation in one Chinese family with piebaldism.

Piebaldism is an autosomal dominant disorder characterized by congenital leukoderma, mostly affecting forehead, abdomen and knee. Previous studies have revealed that piebaldism is caused by mutations of the KIT gene, which encodes the cell surface transmembrane tyrosine kinase receptor for KIT ligand. We reported here a Chinese Han family with piebaldism, and performed mutation detection of KIT gene by direct sequencing.

Psoriasis genome-wide association study identifies susceptibility variants within LCE gene cluster at 1q21.

We report the first large genome-wide association study (GWAS) in a Chinese population to identify susceptibility variants for psoriasis using a two-stage case-control design. In the first stage, we carried out a genome-wide association analysis in 1,139 cases and 1,132 controls of Chinese Han ancestry using Illumina Human 610-Quad BeadChips. In the second stage, we took top SNPs forward for replication in two independent samples of 5,182 cases and 6,516 controls of Chinese Han ancestry, and 539 cases and 824 controls of Chinese Uygur ancestry.

The analysis of genetics and associated autoimmune diseases in Chinese vitiligo patients.

Vitiligo is a common skin and hair depigmentary disorder that results from selective destruction of melanocytes. It occurs in a typical multifactorial, polygenic inheritance. Several studies have indicated that vitiligo is associated with some autoimmune diseases.

Fine mapping of the psoriasis susceptibility locus PSORS1 supports HLA-C as the susceptibility gene in the Han Chinese population.

PSORS1 (psoriasis susceptibility gene 1) is a major susceptibility locus for psoriasis. Several fine-mapping studies have highlighted a 300-kb candidate region of PSORS1 where multiple biologically plausible candidate genes were suggested. The most recent study has indicated HLA-Cw6 as the primary PSORS1 risk allele within the candidate region in a Caucasian population.

Five mutations of ATP2A2 gene in Chinese patients with Darier's disease and a literature review of 86 cases reported in China.

Darier's disease (DD) is an autosomal dominantly inherited skin disorder characterized by loss of adhesion between epidermal cells (acantholysis) and abnormal keratinization. To date, at least 140 mutations in the ATP2A2 gene have been identified as the genetic basis of DD. Here we reported three familial and two sporadic Chinese DD patients totally with four missense mutations (N767D, M494I, M494L, C318F) and one splice-site mutation (1288-6A-->G) in ATP2A2 gene, and presented a literature review of DD cases reported in China since 1989.

Association of HLA class I alleles with aloplecia areata in Chinese Hans.

Background: Some studies suggested that human HLA status may potentiate development of the AA phenotype and exists ethic differences. No report has been published about HLA class I alleles associated with AA in Chinese Hans.

Objective: To study the distribution of HLA class I alleles and haplotypes in Chinese Hans AA patients and the relation of HLA class I profile with age of onset, severity, duration of current attack, past history and family history.

Two frameshift mutations in the RNA-specific adenosine deaminase gene associated with dyschromatosis symmetrica hereditaria.

Objective: To report and analyze the mutations of the double-stranded RNA-specific adenosine deaminase (DSRAD) gene in 2 Chinese pedigrees with dyschromatosis symmetrica hereditaria (DSH).

Design: Pedigree study.

Setting: Anhui province of China.

[Study on clinical isolates of human cytomegalovirus found in Urumqi by restriction fragment length polymorphism of PCR products].

Background: The study was designed to investigate the status of molecular epidemiology of HCMV in Urumqi through genetic comparison of clinical isolates.

Methods: DNA sequences of 2.0-2.
