Exotoxins produced by Actinobacillus (A.) pleuropneumoniae(Apx) play major roles in the pathogenesis of pleuropneumoniain swine. This study investigated the role of ApxI in hemolysisand cellular damage using a novel apxIA mutant, ApxIA336,which was developed from the parental strain A. pleuropneumoniae serotype 10 that produces only ApxI in vitro. The genotype of ApxIA336 was confirmed by PCR, Southernblotting, and gene sequencing. Exotoxin preparation derivedfrom ApxIA336 was analyzed for its bioactivity towardsporcine erythrocytes and alveolar macrophages. Analysisresults indicated that ApxIA336 contained a kanamycinresistantcassette inserted immediately after 1005 bp of theapxIA gene. Phenotype analysis of ApxIA336 revealed nodifference in the growth rate as compared to the parentalstrain. Meanwhile, ApxI production was abolished in thebacterial culture supernatant, i.e. exotoxin preparation. Theinability of ApxIA336 to produce ApxI corresponded to the lossof hemolytic and cytotoxic bioactivity in exotoxin preparation,as demonstrated by hemolysis, lactate dehydrogenase release,mitochondrial activity, and apoptosis assays. Additionally, thevirulence of ApxIA336 appeared to be attenuated by 15-fold inBALB/c mice. Collectively, ApxI, but not other components inthe exotoxin preparation of A. pleuropneumoniae serotype 10,was responsible for the hemolytic and cytotoxic effects onporcine erythrocytes and alveolar macrophages.

Ying-Yun Chen,Rong-Seng Chang,Mi-Yin Tsai,Der-Chin Chen 한국광학회 2015 Current Optics and Photonics Vol.19 No.2

Muscle vibration measurement has long been an unique scientific study, in general, and the directreaction of animals to feel pain (algesia), either from vascular or muscle contraction, is a complexperceptual experience. Thus this paper proposes a way to measure animal algesia quantitatively, bymeasuring the changes in muscle vibration due to a pinprick on the surface of the skin of a Spodopteralitura larva. Using the laser optical triangulation measurement principle, along with a CMOS image sensor,linear laser, software analysis, and other tools, we quantify the subtle object point displacement, with aprecision of up to 10 μm, for our chosen Spodoptera litura larva animal model, in which it is not easyto identify the tiny changes in muscle contraction dynamics with the naked eye. We inject differentconcentrations of formalin reagent (empty needle, 12% formalin, and 37% formalin) to obtain a varietyof different muscle vibration frequencies as the experimental results. Because of the high concentrationsof reagent applied, we see a high frequency shift of muscle vibration, which can be presented as painindices, so that the algesia can be quantified

Background: In intensive care units, mechanical ventilation is an important therapy to help patients with dysp- nea. However, long-term ventilator dependence would consume huge medical resources and increase the risk of morbidity and mortality. The aim of the study was to examine the efficacy of the acupuncture combined with western medical care on ventilator parameters in ventilator-dependent patients. Methods: In this clinical trial, 80 ventilator-dependent patients aged 20 to 80 years old were randomly assigned to acupuncture group and control group in the respiratory care center (RCC) of Changhua Christian Hospital. Besides regular medical care and therapy, participants in the acupuncture group received acupuncture therapy at the same 17 acu-points for 20 minutes once a day, a total of 12 sessions. The ventilator parameters were recorded to evaluate the respiratory efficiency for all participants. The primary outcome was rapid shallow breathing index (RSBI), and secondary outcomes were respiratory rate (RR), tidal volume (TV) and ventilation per minute (MV). Results: Though there was no significant difference in the parameter between the acupuncture group and the control group, we found the trend of decreasing RSBI in the acupuncture group. In subgroup analyses, the mean of RSBI significantly decreased 16.02 (with the SD in 60.84) in acupuncture group, while it increased 17.84 (with the SD in 39.38) in control group (p = 0.036) after 12 sessions. Conclusion: Acupuncture treatment can improve breathing ability of patients with respirator dependence in respiratory care center.

Ru-Band Lu,Yun-Hsuan Chang,Sheng-Yu Lee,Tzu-Yun Wang,Shu-Li Cheng,Po See Chen,Yen Kuang Yang,Jau-Shyong Hong,Shiou-Lan Chen 대한정신약물학회 2020 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.18 No.1

Objective: Valproic acid (VPA) is an anticonvulsant and commonly long term used as a mood stabilizer for patients with mood disorders. However its chronic effects on the hematological changes were noticed and need to be further evaluated. In this study, we evaluated, in Taiwanese Han Chinese patients with bipolar disorders (BD), the chronic effects of VPA or VPA plus dextromethorphan (DM) on the hematological molecules (white blood cell [WBCs], red blood cells [RBCs], hemoglobin, hematocrit, and platelets). Methods: In a 12-week, randomized, double-blind study, we randomly assigned BD patients to one of three groups: VPA plus either placebo (VPA+P, n = 57) or DM (30 mg/day, VPA+DM30, n = 56) or 60 mg/day (VPA+DM60, n = 53). The Young Mania Rating Scale and Hamilton Depression Rating Scale were used to evaluate symptom severity, and the hematological molecules were checked. Results: Paired t test showed that the WBC, neutrophils, platelets and RBCs were significantly lowered after 12 weeks of VPA+P or VPA+DM30 treatment. VPA+DM60 represented the protective effects in the WBCs, neutrophils, and RBCs but not in the platelets. We further calculated the changes of each hematological molecules after 12 weeks treatment. We found that combination use of DM60 significantly improved the decline in neutrophils induced by the long-term VPA treatment. Conclusion: Hematological molecule levels were lower after long-term treatment with VPA. VPA+DM60, which yielded the protective effect in hematological change, especially in the neutrophil counts. Thus, DM might be adjunct therapy for maintaining hematological molecules in VPA treatment.

Po-Wei Lee,Tzu-Yun Wang,Yun-Hsuan Chang,Sheng-Yu Lee,Shiou-Lan Chen,Ze-Cheng Wang,Po See Chen,Chun-Hsien Chu,San-Yuan Huang,Nian-Sheng Tzeng,I Hui Lee,Kao Chin Chen,Yen Kuang Yang,Jau-Shyong Hong,Ru-B 대한정신약물학회 2020 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.18 No.1

Objective: Patients with opioid use disorder (OUD) have impaired attention, inhibition control, and memory function. The aldehyde dehydrogenase 2 (ALDH2 ) gene has been associated with OUD and ALDH2 gene polymorphisms may affect aldehyde metabolism and cognitive function in other substance use disorder. Therefore, we aimed to investigate whether ALDH2 genotypes have significant effects on neuropsychological functions in OUD patients undergoing methadone maintenance therapy (MMT). Methods: OUD patients undergoing MMT were investigated and followed-up for 12 weeks. ALDH2 gene polymorphisms were genotyped. Connors’ Continuous Performance Test (CPT) and the Wechsler Memory Scale-Revised (WMS-R) were administered at baseline and after 12 weeks of MMT. Multivariate linear regressions and generalized estimating equations (GEEs) were used to examine the correlation between the ALDH2 genotypes and performance on the CPTs and WMS-R. Results: We enrolled 86 patients at baseline; 61 patients completed the end-of-study assessments. The GEE analysis showed that, after the 12 weeks of MMT, OUD patients with the ALDH2 *1/*2+*2/*2 (ALDH2 inactive) genotypes had significantly higher commission error T-scores (p = 0.03), significantly lower hit reaction time T-scores (p = 0.04), and significantly lower WMS-R visual memory index scores (p = 0.03) than did patients with the ALDH2 1 */*1 (ALDH2 active) genotype. Conclusion: OUD patients with the ALDH2 inactive genotypes performed worse in cognitive domains of attention, impulse control, and memory than did those with the ALDH2 active genotype. We conclude that the ALDH2 gene is important in OUD and is associated with neuropsychological performance after MMT.

Hsiung, Chao Agnes,Lan, Qing,Hong, Yun-Chul,Chen, Chien-Jen,Hosgood III, H. Dean,Chang, I-Shou,Chatterjee, Nilanjan,Brennan, Paul,Wu, Chen,Zheng, Wei,Chang, Gee-Chen,Wu, Tangchun,Park, Jae Yong,Hsiao, Public Library of Science 2010 PLoS genetics Vol.6 No.8

<▼1><P>Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10<SUP>−7</SUP> or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed associations could be related to tobacco use, lung carcinogenesis, or both. Since most women in Asia do not smoke, we conducted a genome-wide association study of lung adenocarcinoma in never-smoking females (584 cases, 585 controls) among Han Chinese in Taiwan and found that the most significant association was for rs2736100 on chromosome 5p15.33 (p = 1.30×10<SUP>−11</SUP>). This finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls (p = 5.38×10<SUP>−11</SUP>). A pooled analysis achieved genome-wide significance for rs2736100. This SNP marker localizes to the <I>CLPTM1L</I>-<I>TERT</I> locus on chromosome 5p15.33 (p = 2.60×10<SUP>−20</SUP>, allelic risk = 1.54, 95% Confidence Interval (CI) 1.41–1.68). Risks for heterozygote and homozygote carriers of the minor allele were 1.62 (95% CI; 1.40–1.87), and 2.35 (95% CI: 1.95–2.83), respectively. In summary, our results show that genetic variation in the <I>CLPTM1L-TERT</I> locus of chromosome 5p15.33 is directly associated with the risk of lung cancer, most notably adenocarcinoma.</P></▼1><▼2><P><B>Author Summary</B></P><P>Worldwide, approximately 15% of lung cancer cases occur among nonsmokers. Genome-wide association studies (GWAS) of lung cancer conducted in populations of European background have identified three regions on chromosomes 5, 6, and 15 that harbor genetic variants that confer risk for lung cancer. Prior studies were conducted primarily in cigarette smokers, raising the possibility that the associations could be related to tobacco use, lung carcinogenesis, or both. A GWAS of lung cancer among never-smokers is an optimal setting to discover effects that are independent of smoking. Since most women in Asia do not smoke, we conducted a GWAS of lung adenocarcinoma among never-smoking females (584 cases, 585 controls) in Taiwan, and observed a region on chromosome 5 significantly associated with risk for lung cancer in never-smoking women. The finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls. To our knowledge, this study is the first reported GWAS of lung cancer in East Asian women, and together with the replication studies represents the largest genetic association study in this population. The findings provide insight into the genetic contribution of common variants to lung carcinogenesis.</P></▼2>

Genetic variant in TP63 on locus 3q28 is associated with risk of lung adenocarcinoma among never-smoking females in Asia

Hosgood III, H. Dean,Wang, Wen-Chang,Hong, Yun-Chul,Wang, Jiu-Cun,Chen, Kexin,Chang, I-Shou,Chen, Chien-Jen,Lu, Daru,Yin, Zhihua,Wu, Chen,Zheng, Wei,Qian, Biyun,Park, Jae Yong,Kim, Yeul Hong,Chatterje Springer-Verlag 2012 HUMAN GENETICS Vol.131 No.7

<P>A recent genome-wide association study (GWAS) of subjects from Japan and South Korea reported a novel association between the TP63 locus on chromosome 3q28 and risk of lung adenocarcinoma (p = 7.3 10(-12)); however, this association did not achieve genome-wide significance (p 10(-7)) among never-smoking males or females. To determine if this association with lung cancer risk is independent of tobacco use, we genotyped the TP63 SNPs reported by the previous GWAS (rs10937405 and rs4488809) in 3,467 never-smoking female lung cancer cases and 3,787 never-smoking female controls from 10 studies conducted in Taiwan, Mainland China, South Korea, and Singapore. Genetic variation in rs10937405 was associated with risk of lung adenocarcinoma [n = 2,529 cases; p = 7.1 10(-8); allelic risk = 0.80, 95% confidence interval (CI) = 0.74-0.87]. There was also evidence of association with squamous cell carcinoma of the lung (n = 302 cases; p = 0.037; allelic risk = 0.82, 95% CI = 0.67-0.99). Our findings provide strong evidence that genetic variation in TP63 is associated with the risk of lung adenocarcinoma among Asian females in the absence of tobacco smoking.</P>

Association of the PPAR-γ Gene with Altered Glucose Levels and Psychosis Profile in Schizophrenia Patients Exposed to Antipsychotics

Yun-Ru Liu,El-Wui Loh,Tsung-Ming Hu,Tsuo-Hung Lan,Hsien-Jane Chiu,Yung-Han Chang,Shuo-Fei Chen,Yen-Hsin Yu,Cheng-Chung Chen 대한신경정신의학회 2014 PSYCHIATRY INVESTIGATION Vol.11 No.2

Objective Metabolic abnormalities, e.g., diabetes, are common among schizophrenia patients. Peroxisome proliferator activated receptor-γ (PPAR-γ) regulates glucose/lipid metabolisms, and schizophrenia like syndrome may be induced by actions involving retinoid X receptor-α/PPAR-γ heterodimers. We examined a possible role of the PPAR-γ gene in metabolic traits and psychosis profile in schizophrenia patients exposed to antipsychotics. Methods Single nucleotide polymorphisms (SNPs) of the PPAR-γ gene and a serial of metabolic traits were determined in 394 schizophrenia patients, among which 372 were rated with Positive and Negative Syndrome Scale (PANSS). Results SNP-10, -12, -18, -19, -20 and -26 were associated with glycated hemoglobin (HbA1c) whereas SNP-18, -19, -20 and -26 were associated with fasting plasma glucose (FPG). While SNP-23 was associated with triglycerides, no associations were identified between the other SNPs and lipids. Further haplotype analysis demonstrated an association between the PPAR-γ gene and psychosis profile. Conclusion Our study suggests a role of the PPAR-γ gene in altered glucose levels and psychosis profile in schizophrenia patients exposed to antipsychotics. Although the Pro12Ala at exon B has been concerned an essential variant in the development of obesity, the lack of association of the variant with metabolic traits in this study should not be treated as impossibility or a proof of error because other factors, e.g., genes regulated by PPAR-γ, may have complicated the development of metabolic abnormalities. Whether the PPAR-γ gene modifies the risk of metabolic abnormalities or psychosis, or causes metabolic abnormalities that lead to psychosis, remains to be examined.
