    Abstract Background: Tic disorders (TD) is a neuropsychiatric disease with twitch as the main manifestation in childhood. Jiu-Wei-Xi-Feng granules has been marketed in China for treating children with TD. As Long Gu (Os Draconis) in the composition of this Chinese patent medicine is a rare and expensive medicinal material protected by the Chinese government, therefore, we consider replacing it with Mu Li (Concha Ostreae) that has the same effect and is cheaper. This study is designed to evaluate the clinical equivalence between Jiu-Wei-Xi-Feng granules (Os Draconis replaced by Concha Ostreae) (JWXFD) and Jiu-Wei-Xi-Feng granules (original formula) (JWXFO) in children with TD (consumption of renal yin and liver wind stirring up internally syndrome).
    Methods/design: This is a multicenter, randomized, double-blind, equivalence trial comparing the efficacy and safety of JWXFD and JWXFO in treating Children with tic disorders (consumption of renal yin and liver wind stirring up internally syndrome). A total of 288 patients will be recruited and randomly assigned to two groups in a 1:1 ratio. The treatment course is 6 weeks, with a 2 weeks follow-up. The primary outcome is the mean change value from baseline to 6th week by the Yale Global Tic Severity Scale total tic score (YGTSS-TTS). Secondary outcomes include total effective rate of tic, Yale Global Tic Severity Scale (YGTSS) scores and its factor scores (the degree of motor tics, phonic tics and social function damage), Clinical Global Impression-Severity scale, and TCM syndrome efficacy.
    Discussion: The design of this study refers to a large number of similar research design points, and asked for opinions of peer experts, and finally reached a consensus. This trial will provide high-quality evidence on the clinical equivalence between JWXFD and JWXFO and provide a basis for the marketing of JWXFD.

    Abstract Natural NQO1 [NAD(P)H quinine oxidoreductase 1] inducing agents play a critical role in cancer chemoprevention. The expression of NQO1 is regulated by Michael reaction acceptors (MRAs) via the Keap1/Nrf2/ARE signaling pathway. The aims of this study were to identify and characterize novel effective chemopreventive agents from naturally occurring products. Using bioassay-guided isolation approaches 16 bioactive MRAs from Millettia pulchra Kurz var-laxior (Dunn) Z.Wei, also called Yulangsan as a famous Zhuang medicine. The structures were elucidated as chalcone (1-7), flavonone (8-14), flavanone (15) and isoflavan (16). Their electrophilic abilities and NQO1 inducing activity were assessed using GSH (glutathione) rapid screening, and in vitro cell-based (Hepa 1c1c7 cells) assay, respectively. Compounds 3, 4, 6, 13, and 14 showed to have NQO1 inducing activity. Among them, compounds 4 and 14 interact with NQO1 at Gly 149, Gly 150, Phe 106, Typ 105 and His 161, revealed by molecular docking studies.

    Abstract Indoor air pollution has been documented as an important risk factor for chronic obstructive pulmonary disease (COPD), and inflammation is central to the development and progression of COPD. Single nucleotide polymorphisms (SNP) in some cytokine genes have been reported to be associated with COPD. We examined the association between 18 SNPs in 10 cytokine genes and COPD risk in a case-control study conducted in a population with high exposure to indoor smoky coal emissions. The study included 53 COPD cases and 122 healthy community controls. Carriers of the CSF2 117Ile allele had a 2.4-fold higher risk of COPD than the wild type (Thr/Thr) carriers (OR: 2.44; 95% CI: 1.10-5.41), and the AA genotype at IL8 -351 was associated with an increased risk of COPD (OR: 2.71; 95% CI: 1.04-7.04). When the combined effects of CSF2 117Ile and IL8 -351A were examined, individuals carrying at least one variant in both genes had a five-fold increased risk of COPD (OR: 5.14, 95% CI: 1.32-29.86). This study suggests that polymorphisms in both CSF2 and IL8 may play a role in the pathogenesis of COPD, at least in highly exposed populations. However, in view of our relatively small sample size, this study should be replicated in other populations with substantial exposure to indoor air pollutants such as polycyclic aromatic hydrocarbons (PAH) and particulate matter.

    Abstract We conducted a population-based case-control study in Xuan Wei, China, where lung cancer rates are among the highest in China due to exposure to indoor coal combustion products, to evaluate the association between polymorphisms in immunoregulatory genes and lung cancer risk. A total of 122 incident primary lung cancer cases and 122 individually matched controls were enrolled in Xuan Wei, China. Fifty single-nucleotide polymorphisms (SNPs) in 23 immunoregulatory genes involved in inflammation were genotyped and analyzed by logistic regression to assess the risk of lung cancer. A global test of association for 42 SNPs, which excluded eight SNPs that were in very tight linkage disequilibrium with other SNPs, was statistically significant (P = 0.01), suggesting that overall genetic variation in this pathway contributes to lung cancer risk. In addition, the IL1B -1060TT (i.e. -511TT) genotype was associated with increased lung cancer risk compared with the CC genotype [odds ratio (OR) = 2.27, 95% confidence interval (CI) = 1.05-4.91]. The IL8RA Ex2+860 GC or CC (OR = 0.27, 95% CI = 0.11-0.67), ICAM1 Ex2+100 AT or TT (OR = 0.39, 95% CI = 0.18-0.88) and IL12A Ex7+277 GA or AA (OR = 0.43, 95% CI = 0.22-0.84) genotypes were associated with decreased lung cancer risk. The protective effect of the IL8RA variant was stronger among subjects with high cumulative smoky coal use (> or = 130 tons) (OR = 0.11, 95% CI = 0.03-0.44; P(interaction) = 0.03). In conclusion, genetic variation in immunoregulatory genes may play an important role in the development of lung cancer in this population.

    Abstract The aim of this study is to investigate the role of genetic polymorphisms in twelve folate metabolism genes on the risk of lung cancer in Xuan Wei, China, where the lung cancer mortality rate is among the highest and is mainly caused by indoor smoky coal emissions. A total of 122 incident primary lung cancer cases and 122 matched controls were enrolled. Three single nucleotide polymorphisms were associated with increased risk of lung cancer including homozygotes of the C allele of CBS Ala360Ala (OR: 4.02; 95% CI: 1.64-9.87), the 222Val allele of MTHFR (OR: 2.32; 95% CI: 1.34-4.03), and the C allele of SLC19A1 Pro232Pro (OR: 1.83; 95% CI: 1.02-3.28). The distribution of CBS and MTHFR haplotypes differed between cases and controls (P=0.002 and P=0.07, respectively). In summary, three genetic variants in folate metabolism genes are associated with an increased risk of lung cancer in Xuan Wei, China.

    Abstract The lung cancer mortality rate in Xuan Wei is among the highest in China and has been causally attributed to high exposure to indoor smoky coal emissions, which contain high levels of PAHs and can lead to modified bases. We studied genetic polymorphisms in four DNA base excision repair genes in a population-based case-control study in Xuan Wei with 122 lung cancer cases and 122 controls. Homozygous carriers of the APEX1 148Glu variant had an increased risk (OR, 2.13; 95% CI, 0.96-4.74), whereas persons with the XRCC1 399Gln allele had a decreased risk (OR, 0.60; 95% CI, 0.35-1.02) of lung cancer compared with wild-type carriers. Subjects with both at-risk genotypes (APEX1 Glu148Glu and XRCC1 Arg399Arg) had a higher risk of lung cancer (OR: 3.34; 95% CI: 1.16-9.67). We found genetic variants in APEX1 and XRCC1 may alter the risk of lung cancer in a special population in China.

    Abstract The lung cancer mortality rate in Xuan Wei County is among the highest in China and has been attributed to exposure to indoor smoky coal emissions that contain very high levels of polycyclic aromatic hydrocarbons (PAHs). Nucleotide excision repair (NER) plays a key role in reversing DNA damage from exposure to environmental carcinogens, such as PAHs, that form bulky DNA adducts. We studied single nucleotide polymorphisms (SNPs) and their corresponding haplotypes in 6 genes (ERCC1, ERCC2/XPD, ERCC4/XPF, ERCC5/XPG, RAD23B and XPC) involved in NER in a population-based case-control study of lung cancer in Xuan Wei. A total of 122 incident primary lung cancer cases and 122 individually matched controls were enrolled. Three linked SNPs in ERCC2 were associated with lung cancer with similar ORs; e.g., persons with the Gln allele at codon 751 had a 60% reduction of lung cancer (OR = 0.40, 95% CI 0.18-0.89). Moreover, one haplotype in ERCC2 was associated with a decreased risk of lung cancer (OR = 0.40, 95% CI 0.19-0.85) compared to the most common haplotype. In addition, subjects with one or 2 copies of the Val allele at codon 249 of RAD23B had a 2-fold increased risk of lung cancer (OR = 1.91, 95% CI 1.12-3.24). In summary, our results suggest that genetic variants in genes involved in the NER pathway may play a role in lung cancer susceptibility in Xuan Wei. However, due to the small sample size, additional studies are needed to evaluate these associations within Xuan Wei and in other populations with substantial environmental exposure to PAHs.

    Abstract Lung cancer rates in Xuan Wei County are among the highest in China and have been associated with exposure to indoor smoky coal emissions that contain high levels of polycyclic aromatic hydrocarbons (PAHs). The NBS1 gene product participates in DNA double-strand break repair and DNA damage-induced checkpoint activation, which are critical for maintaining genomic integrity. The p53 tumor suppressor gene is known to play key roles both in the maintenance of genomic stability in mammalian cells and in DNA damage surveillance. We examined the association between two common NBS1 polymorphisms (Leu34Leu, Gln185Glu) and lung cancer risk in a population-based case-control study in Xuan Wei, China. Individuals homozygous for the NBS1 34Leu or NBS1 185Glu variants were found to have an increased risk of lung cancer (odds ratio [OR] 2.15, 95% confidence interval [CI]: 0.91-5.10 and OR 2.53, 95% CI: 1.05-6.08, respectively). A haplotype containing the variant alleles from both NBS1 SNPs was associated with increased risk of lung cancer compared with the most common haplotype. Further, the associations were particularly pronounced among cases with over expression of p53 protein. These results suggest that NBS1 could be important in the pathogenesis of lung cancer in this population. However, additional studies in other populations with substantial environmental exposures to PAHs are needed to confirm our findings.
