AIM: To investigate the relationship between the polymorphism of related gene loci of miRNAs regulated fibrinopeptide A and schizophrenia. Lay the foundation for the aetiology of schizophrenia. METHODS: Adapt to the phase match of sex and age case-control study, a total of 513 Chinese Han patients with schizophrenia were selected as the case group, 513 normal healthy persons as a control group. Obtaining SNPs information of the FGA gene by querying the dbSNP database, and reference HapMap database included SNPs site frequency information for screening. The frequency distributions of SNPs were genotyped by iMLDR® SNP detection technology. Two SNPs (pre-hsa-miR-605rs2043556 T>C, pre-hsa-miR-499a/pre-hsa-miR-499brs4909237 T < C) were analyzed to demonstrate their association with susceptibility to schizophrenia. RESULTS: There were no significant differences between patients and controls in genotype and allele distribution of SNPs(rs2043556 and rs4909237)in the precursor region of hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b. Their gene-gene interaction, which suggests that the polymorphisms of miRNA genes might not contribute to schizophrenia susceptibility in the Han Chinese population. CONCLUSION: No significant difference existed between schizophrenic patients and controls in SNP (rs2043556 and rs4909237) in the precursor region of hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b. There may not regulate FGA gene expression. Thus, hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b may not influence the risks of schizophrenia.

Background: Migraine is an important cause of headache and headache-related disabilities. It increases loss of working time, causes inability to carry out daily activities and disruption of family and social life. The pathophysiology of migraine is still poorly understood. On the other hand, the prevalence of obesity is constantly increasing worldwide. The consequence of overweight and obesity includes increased risk of diabetes mellitus, dyslipidemia, hypertension, cardiovascular disease and cancer.Objectives: This study was performed to assess the relationship between BMI and migraine by finding out the relationship between migraine frequency and duration in different BMI groups, comparing the socio-demographic variables in migraine and non-migraine patients and to find out the migraine related co-morbidities.Materials and Methods: This observational case-control study was conducted on 100 subjects aged 12–50 years in the Neurology Outpatient Department, Mymensingh Medical College Hospital, Mymensingh in the period of January 2011 to December 2012. Out of total subjects fifty migraine patients were selected as cases and fifty nonmigraineurs as controls. Subjects were then categorized in three groups based on BMI: <23, 23 to 25 and >25. Collected data were compiled and appropriate analyses were done by using computer based software, Statistical Package for Social Sciences (SPSS) version 16.0. For statistical analysis one way ANOVA tests were done for comparing means of quantitative data and Chi-square tests were done for qualitative data. A p value <0.05 was considered statistically significant.Results: In this study, majority (>95%) of the study subjects were between 10 and 35 years of age. Mean age of case group was found 25.55 ± 5.87 and that of control was 25.53 ± 4.22 years. Case group contained 10 (20%) males and 40 (80%) females whereas control group had 14 (28%) males and 36 (72%) females. Number of female cases and controls were higher than that of male. In control group 30 (60%) were unmarried and 20 (40%) were married. There was no significant difference in the financial condition between case and control groups. Students and housewives occupied the largest number of study subjects who were unemployed. Regarding residence, rural and urban patients were equal in case group and in control group 29 (58%) were urban and 21 (42%) rural. Mean duration of headache was 8.9 ± 7.5, 5.8 ± 6.7, 9.6 ± 14.3 years in different BMI groups (<23, 23–25, >25 respectively) in case group and 4.6 ± 5.3, 4.4 ± 3.4, 3.4 ± 1.4 years in control group respectively. There was significant difference in quality of headache. In migrainous group 58.6% in BMI <23, 30% in BMI 23–25, 36.4% in BMI >25 noted their headache as throbbing, in contrast most of the nonmigrainous described them as dull in nature. Mean frequency of headache per month was significantly higher in migraine group compared to non-migraine group (p=0.02). Regarding associated symptoms, nausea, vomiting, photophobia and phonophobia were observed significantly higher in migraine patients in BMI <23 group. Odd ratios (ORs) for vomiting, photophobia and phonophobia with 95% confidence interval (CI) were 23.385 (2.752–97.739), 16.500 (3.060– 88.971) and 13.000 (2.922–57.846) respectively. Smoking was found significantly higher in nonmigrainous group than migraine group in case of BMI <23.Conclusion: From the result of present study it can be concluded that there is statistically no significant relation of BMI with frequency of headache, but some relationship were observed for associated symptoms of migraine with low BMI.J Enam Med Col 2016; 6(2): 80-87

Lp(a) has been well known as an independent risk factor for coronary artery disease (CAD). TheLPAgene, as it encodes apo(a) of the Lp(a) lipoprotein particle, was associated with increased risk of CAD. The purpose of this study was to analyze the relationship between the polymorphisms ofLPAgene and CAD in Chinese Han population. Five SNPs (rs1367211, rs3127596, rs6415085, rs9347438, and rs9364559) in theLPAgene were genotyped using Sequenom MassARRAY time-of-flight mass spectrometer (TOF) in 560 CAD patients as case group and 531 non-CAD subjects as control group. The numbers of these two groups were from Chinese Han ancestry. The results showed that allele (P=0.046) and genotype (P=0.026) of rs9364559 in theLPAgene was associated with CAD. The frequency of rs9364559 minor allele (G) in case group was obviously higher than that in control group. Results of haplotype analysis showed that 4 haplotypes which contained rs9364559-G were associated with increased risk of CAD in this population. This study explored rs9364559 in theLPAgene may be associated with the pathogenesis of CAD; and the risk of CAD might be higher in the population carrying 4 haplotypes of different blocks in theLPAgene.

BACKGROUND Coronary artery disease is multifactorial in origin. Coronary artery disease predisposition is attributed to genetic factors also. Many gene polymorphisms are implicated out of which paraoxonase 1 (PON 1) gene is an important one. The product of paraoxonase gene is paraoxonase enzyme which is seen in serum associated with high density lipoprotein (HDL). This enzyme is mainly synthesised by the liver. The protective effect of HDL is attributed to the presence of such enzymes on it. Gln to Arg polymorphism at position 192 confers a risk of developing atherosclerosis and coronary artery disease (CAD). This study is done to assess the genotype distribution of PON 1 gene in CAD patients compared to healthy controls in a population from Kerala. METHODS The case group consists of 100 angiographically proven CAD patients with no history of hypertension, diabetes mellitus, hepatic disease or smoking. The control group had 100 healthy controls from the general population. PON 1 gene was amplified by a polymerase chain reaction (PCR) technique already reported and restriction fragment length polymorphism by the restriction enzyme Alwl was done to assess the polymorphism. to assess the polymorphism. RESULTS In this study, the frequency of heterozygous genotype QR was 86 % in control and 76 % in cases. Though there was no significant difference in allele distribution of Q or R, RR genotype was significantly higher in the case group ( 2 = 8.82; p value = .012). With binary logistic regression model, adjusting for age and sex, RR genotype is independently associated with CHD. Adjusted odds ratio of RR was 5.24 with 95 % confidence interval (CI) 1.41 - 19.47 for developing CHD (p < 0.05). CONCLUSIONS The RR genotype is more frequently seen in CAD patients than in controls. The QR genotype is more frequent than QQ or RR in both cases and controls. KEYWORDS Coronary Artery Disease, Paraoxonase, Gene Polymorphism

Abstract Using a case–control design, we assessed the association between single nucleotide polymorphisms (SNPs) of growth and differentiation factor 5 (GDF5)/rs143383 gene and interaction with environments and knee osteoarthritis (KOA). We recruited 288 KOA patients from the First Clinical College, Henan University of Chinese Medicine between June 2017 and May 2018. There was significant difference in genotype distribution between case group and control group (χ2 = 22.661, P=0.000). The minor C allele was significantly higher in the case group than that in the control group (20.5 vs 8.1%, P=0.000, odds ratio (OR) = 1.62, 95% confidence interval (CI): 1.29–2.03). Significant differences were also observed in other gene models. For age, all models show significant differences (P<0.05) for those whose age was more than 60 years, and no significant difference was observed for those under 60 years. For non-smoking group, there were significant differences between case group and control group, and for smoker, significance level was found in TT compared with CC and allele gene models. Patients with drinking and Bbody mass index (MI )≥ 24 also showed significant relationship between rs143383 and osteoarthritis (OA) under the following models: TT vs CC (P=0.000, P=0.018), TT/CT vs CC (P=0.043), TT vs CT/CC (P=0.000, P=0.009), and T vs C (P=0.024, P=0.000). Other gene models indicated no significance (P>0.05). Our results revealed a possible genetic association between GDF5 and KOA, and the TT genotype of rs143383 increased the risk of KOA in Chinese Han population. The interaction between GDF5 gene and drinking, smoking, and obesity further increased the risk of KOA.

Concurrent falls in milk production and electrical resistance of composite milk were examined in Israeli Holstein cows. The cows were milked three times a day by a system that recorded yield and the lowest electrical resistance in the composite milk from the four glands. The study included two groups: cows that experienced on day 0 a decline in resistance and milk production [ges ]20% from the mean of the previous 9 d (62 cows, case group) and cows that experienced no such episodes over 9 d before and after a fixed day (118 cows, control group). Bacteriological status and somatic cell count (SCC) or California mastitis test scores were assessed on the fixed day in the control group, and on days 0, 1 and 2 in the case group. California mastitis test scores greater than 2 and SCC thresholds of 5×105 cells/ml were used to create two classes of leucocytosis. There was no statistically significant difference between the two groups in frequency distributions of pathogens and their types: in 30% of cows infection was not detected, 33% were infected by major pathogens (95% of which were Staphylococcus aureus), and 53·5% by minor pathogens (80% Micrococcus spp.). Cows in the case group had lower milk production during the 8 d following day 0. Mean electrical resistance was lower in infected cows and particularly in cows infected by Staph. aureus. High leucocytosis was associated with reduced electrical resistance in both groups, and was found in 93% of cows in the case group v. 25% in the control group. The results suggest that falls in electrical resistance of milk and in milk production were not linked to a specific pathogen, and were followed by 3–8 d of reduced milk production and electrical resistance. The study suggests that there are episodic aggravations in mammary health that do not evolve into clinical mastitis but may induce significant losses in milk yield and quality.

Abstract Background Xeroderma pigmentosum complementation group C (XPC) is a DNA damage recognition protein that plays an important role in nucleotide excision repair and can reduce oxidative stress, which may be involved in the development of preeclampsia (PE). Therefore, the aim of this study was to explore whether XPC polymorphisms were relevant to the genetic susceptibility to PE in Chinese Han women. Method A total of 1276 healthy pregnant women were included as the control group and 958 pregnant women with PE as the case group. DNA was extracted from peripheral blood samples to perform genotyping of loci rs2228001 and rs2228000 in XPC through real-time quantitative polymerase chain reaction (PCR). The relationship between XPC and susceptibility to PE was evaluated by comparing the genotypic and allelic frequencies between the two groups of pregnant women. Results Polymorphism of rs2228000 may be associated with PE risk and allele T may play a protective role (genotype, χ2 = 38.961, P < 0.001 and allele χ2 = 21.746 P < 0.001, odds ratio (OR) = 0.885, 95% confidence interval (CI) = 0.840-0.932). No significant difference was found between the two groups in rs2228001,(genotype χ2 = 3.148, P = 0.207 and allele χ2 = 0.59, P = 0.442, OR = 1.017, 95% CI = 0.974–1.062). When the frequencies of genotypes and alleles for early- and late-onset PE, mild PE and severe PE were compared with those of controls, the results were consistent with the large clinical sample. Conclusion Our data suggest that the genetic variant rs2228000 in XPC may be associated with PE risk in Chinese Han women, and that pregnant women with the TT genotype have a reduced risk of PE. Further investigations are needed to confirm these findings in other regions or larger prospective populations.

Chronic constipation is one of the most common problems in children. It can cause anxiety and psychological problems in patients and parents. The purpose of this study was to investigate the relationship between obsessive-compulsive disorders (OCD) in children with chronic functional constipation. This is a case-control study performed at the gastroenterology clinic of Besat Hospital Sanandaj for one year. The children aged 7-14-year-old with chronic functional constipation were selected as a case group, and the healthy children were recruited as a control group, who referred for growth control. Then, the Maudsley questionnaire for obsessive-compulsive disorders was completed by a trained assistant. With this questionnaire, the presence or absence of OCD and its type can be determined. Forty-three children were selected as the case group and sixty-seven children as the control group. The mean age of the case and control group was 9.3±1.5 and 8.8±1.6 years, respectively. Based on the results, there was a significant difference between the groups in terms of checking, cleaning, slowness, doubting, and total obsessive score (P˂0.05). Therefore, all five types of obsessive-compulsive disorder in the case group were greater than the control group. Obsessive-compulsive disorders were more common in children with functional constipation, and the total obsessive score in these children than the healthy children was a significant difference.

Psoriasis is a common disease in dermatology, but its etiology and pathogenesis have not been fully elucidated. In recent years, researchers have found that HOX transcript antisense RNA (HOTAIR) plays an important role in biological processes as an important long-chain noncoding RNA (lncRNA). The goal of this study was to investigate the association between HOTAIR polymorphisms and psoriasis in a Chinese Han population by screening key candidate single-nucleotide polymorphism (SNPs) sites in HOTAIR. A total of 269 patients diagnosed with psoriasis and 273 healthy control subjects were enrolled in this case-control study. Three SNPs of HOTAIR were genotyped: SNP1 (rs12826786), SNP2 (rs1899663), and SNP3 (rs4759314). All polymorphisms were in Hardy-Weinberg equilibrium in both the control and patient groups, and the SNPs were in linkage disequilibrium. The distribution of the rs4759314 genotype in the control group and case group was statistically significant according to all the models except the recessive model (adjusted p value < 0.05), and the CCG haplotype group had a significant difference ( OR   95 % CI = 2.907   1.344 − 6.289 , adjusted p value = 0.0263). rs12826786 was associated with a risk of psoriasis according to the dominant model (C/T-T/T vs. C/C: OR   95 % CI = 0.70   0.48 − 1.01 , adjusted p value = 0.049) and overdominant model (C/T vs. C/C-T/T: OR   95 % CI = 0.69   0.47 − 1.01 , adjusted p value = 0.048). The current work showed that a genomic variant within HOTAIR was associated with a risk of psoriasis, and the clinical value of this study should be further evaluated in the future.

Objectives: To study the two gene polymorphism (DENND1A and THADA genes) among Iraqi women with polycystic ovary syndrome (PCOS). Materials and Methods: This case-control study was done at the Gynaecological Department of Al-Yarmouk Teaching Hospital of AI-Mustansiriyah College of Medicine, Baghdad during January-December 2018. Two-hundred women were enrolled in the study, including 100 women with PCOS as the case group and 100 healthy and age-matched women as the control group. Main outcome measures were to analyze DENND1a gene polymorphism rs2479106 and THADA gene polymorphism rs12478601 at genotype and allelic levels. Results: The DENND1A gene polymorphism rs2479106 had three genotypes of AA, AG, and GG. The homozygous mutant genotype (GG) was considerably related to the incidence of PCOS (OR=5.43, 95% CI=1.13-25.97, P=0.034) with 5-time more risk compared with those carrying the wild homozygous genotype (AA). The heterozygous genotype (AG) was more but not statistically different (OR=1.73, 95% CI=0.85-3.54, P=0.131). At the allelic level, G allele was two times more frequent among cases compared to control cases with a highly significant difference. THADA gene polymorphism rs12478601 had three genotypes of CC, CT, and TT. Although TT genotype was repeated more among the case group than controls, the difference was not significant (P=0.346). Likewise, no significant differences were found in the allele distribution of this polymorphism. Conclusions: In general, the DENND1A-rs 2479106 polymorphism was considerably related to the incidence of PCOS among Iraqi women while THADA-rs12478601 polymorphism was not.

Abstract Objective: This study aimed to investigate the association between p73 C14T (rs1801173) polymorphism and the risk of GC in a Chinese Han population. Methods: A hospital-based case-control study was conducted. A total of 577 GC cases and 678 normal controls were recruited. Their genotypes were determined using the SnapShot method. Results: The genotype frequency distribution of the case group and the control group were consistent with the Hardy–Weinberg equilibrium. No significant difference was found in the distribution of gender, age, and drinking history between the case group and the control group. A correlation was observed between smoking and the incidence of GC (P = 0.006). Three genotypes of CC, CT, and TT were found in the rs1801173 locus of p73. The distribution of the dominant model/recessive model did not significantly differ (P = 0.688; 0.937). No statistical difference was found even after adjustment was performed via logistic regression analysis (P = 0.703; 0.990). The frequency distribution between the two groups also did not significantly differ (P = 0.763). Conclusion: Smoking is related to the occurrence and development of GC. No association was found between p73 rs1801173 C > T SNP and the risk of GC in a Chinese Han population. However, additional larger studies and tissue-specific biological characterization are required to confirm these findings.
