M235t Polymorphism

Objective: To explore the relationship between the polymorphism of angiotensinogen gene (AGT) M235T and susceptibility to hypertrophic cardiomyopathy (HCM) in Asian population by meta-analysis. Methods: PubMed, Embase, Web of Science, Cochrane library, CNKI, Wan Fang, and other databases were searched to collect the literature about AGT M235T polymorphism and HCM from the inception to March 1, 2020. The Newcastle-Ottawa Scale (NOS) checklist was uesd to perform independent literature review and study quality assessment. Data was analyzed by Stata 15.0 software. Results: The results showed that, except for the recessive genetic model (TT vs MT+MM: OR = 1.27, 95%CI: 1.05–1.53), in the other four genetic models, the M235T polymorphism had no significant correlation with the risk of HCM (T vs M: OR = 1.17, 95%CI: 0.88–1.57; TT+MT vs MM: OR = 1.13, 95%CI: 0.55–2.33; TT vs MM: OR = 1.25, 95%CI: 0.60–2.59; TM vs MM: OR = 0.95, 95%CI0.5–1.82). The results of subgroup analysis showed that, except for the heterozygous genetic model, in the other four genetic models, M235T polymorphism was significantly associated with sporadic hypertrophic cardiomyopathy (SHCM), but not with familial hypertrophic cardiomyopathy (FHCM) ( p > 0.05). Conclusion: M235T polymorphism in Asians is associated with HCM, especially SHCM. Heterozygotes increase the risk of patients with SHCM.

AbstractThe present study was aimed to evaluate the association of lipoprotein lipase (LPL) gene (S447X and Hind III) polymorphisms and T2DM. Relevant studies were identified through systematic search PubMed, Cochrane Library, Embase, Wanfang, CNKI databases. A total of 22 studies (8 studies for LPL S447X and 14 studies for Hind III) were included. The results showed that the LPL S447X polymorphism was associated with the low risk of T2DM under dominant and allelic genetic models. Subgroup analysis by ethnicity showed that the LPL S447X polymorphism was associated with a decreased risk of T2DM in the Asian population (under dominant, heterozygous and allelic genetic models). In addition, we found that X allele carriers of S447X polymorphism is associated with low levels of TC, TG, and LDL. In subgroup analysis, Hind III polymorphism was associated with low risk of T2DM in Asian populations (under dominant, heterozygote, allele genetic models). Moreover, the carriers of H allele of Hind III have lower levels of TG, and higher levels of HDL-C. This meta-analysis demonstrated that 447X carriers and H allele in LPL gene associated with low risk of T2DM, which may due to in part to the change of serum level of TC, TG, LDL, and HDL.

Background: ACE gene polymorphisms have recently been shown to be associated with risk of developing left ventricular hypertrophy (LVH). However, the results were controversial. We aimed to conduct this meta-analysis to further confirm the association between ACE rs4646994 polymorphism and HCM/DCM. Methods: PubMed, EMBASE, the Chinese national knowledge information database, and Wan fang databases were searched for eligible studies. The Newcastle-Ottawa Scale was used to evaluate the quality of included studies. Then we evaluated the association between ACE gene mutation and HCM/DCM by calculating odds ratios and 95% confidence intervals. Subgroup analysis was further performed to explore situations in specialized subjects. Sensitivity analysis and publication bias was assessed to confirm the study reliability. Results: There were 13 studies on DCM (2004 cases and 1376 controls) and 16 studies on HCM (2161 controls and 1192 patients). ACE rs4646994 polymorphism was significantly associated with DCM in all genetic models. However, in HCM, four genetic models (allele model, homozygous model, heterozygous model and dominant model) showed significant association between ACE rs4646994 polymorphism and DCM. In subgroup analysis, we found that ACE rs4646994 polymorphism was significantly associated with DCM / HCM in Asian population. Finally, we also conducted a cumulative meta-analysis, which indicates that the results of our meta-analysis are highly reliable. Conclusion: ACE rs4646994 polymorphism increases the risk of DCM / HCM in Asian, but not in Caucasian. More case-control studies are needed to strengthen our conclusions and to assess the gene-gene and gene-environment interactions between ACE rs4646994 polymorphism and DCM / HCM.

Abstract In recent years, investigators have been striving to explore the pathogenesis of chronic obstructive pneumonia disease (COPD). Hedgehog Interacting Protein (HHIP) has been identified as a candidate susceptibility gene. Our aim is to synthesize and include all evidences to get a more comprehensive result. We searched 6 online databases- PubMed, Web of Science, Cochrane Library, Wanfang, EMBASE, CNKI. All included studies were published before October 1, 2021. We used Newcastle-Ottawa scale (NOS) to evaluate the bias of each study. Meta-analysis methods were conducted to evaluate the pooled result. A total of 14 comparative studies were included in this meta-analysis, for rs13118928 polymorphism, significant associations were observed in 5 genetic models, (A vs. G, OR=1.18, 95CI%=[1.07-1.30], P=0.0006; AA vs. GG, OR=1.56, 95CI%=[1.22-2.00], P=0.0004; AG vs. GG, OR=1.28, 95CI%=[1.05-1.55], P=0.01; AA+AG vs. GG, OR=1.36, 95CI%=[1.12-1.65], P=0.002; AA vs. AG+GG, OR=1.18, 95CI%=[1.05-1.33], P=0.006). as for rs1828591, there were also significant associations detected in the overall population, (A vs. G, OR=1.12, 95CI%=[1.05-1.19], P=0.0003; AA vs. GG, OR=1.27, 95CI%=[1.04-1.56], P=0.02; AG vs. GG, OR=1.25, 95CI%=[1.03-1.51], P=0.02; AA+AG vs. GG, OR=1.26, 95CI%=[1.04-1.53], P=0.02; AA vs. AG+GG, OR=1.10, 95CI%=[1.01-1.19], P=0.03). This meta-analysis showed that the A allele in both rs13118928 and rs1828591 was turn out to be the risk allele in developing COPD. The result of Codominant genetic model, Dominant genetic model and Recessive genetic model remain the same.

BackgroundPrevious studies have revealed the critical role of methylene tetrahydrofolate reductase (MTHFR) polymorphisms in response to high-dose methotrexate (MTX)-induced toxicity in osteosarcoma patients. However, the conclusions remain controversial. In this setting, we performed a meta-analysis to determine their association more precisely.MethodEligible studies were searched and screened in PubMed, Web of Science, Cochrane Library, Clinical-Trials.gov, Embase, and China National Knowledge Infrastructure (CNKI) following specific inclusion and exclusion criteria. The required information was retrieved and collected for subsequent meta-analysis. Association between MTHFR polymorphism and MTX toxicity was evaluated by odds ratios (ORs).ResultsSeven studies containing 585 patients were enrolled and analyzed in this meta-analysis. Overall, the MTX related grade 3-4 liver toxicity was significantly associated with MTHFR rs1801133 allele (T vs. C: OR=1.61, 95%CI=1.07-2.42, P=0.024), homozygote (TT vs. CC: OR=2.11, 95%CI=1.06-4.21, P=0.011), and dominant genetic model (TT/TC vs. CC: OR=3.15, 95%CI=1.30-7.60, P=0.035) in Asian population. Meanwhile, close associations between MTX mediated grade 3-4 mucositis and MTHFR rs1801133 polymorphism were identified in allele contrast (T vs. C: OR=2.28, 95%CI=1.49-3.50, P<0.001), homozygote comparison (TT vs. CC: OR=4.07, 95%CI=1.76-9.38, P=0.001), heterozygote comparison (TC vs. CC: OR=2.55, 95%CI=1.20-5.42, P=0.015), recessive genetic model (TT vs. TC/CC: OR=2.09, 95%CI=1.19-3.67, P=0.010), and dominant genetic model (TT/TC vs. CC: OR=2.97, 95%CI=1.48-5.96, P=0.002). Additionally, kidney toxicity was corelated with the heterozygote comparison (TC vs. CC: OR=2.63, 95%CI=1.31-5.29, P=0.007) of rs1801133 polymorphism.ConclusionThe MTHFR rs1801133 polymorphism was significantly associated with severer liver toxicity induced by high-dose MTX treatment in the Asian population. In the meantime, patients with MTHFR rs1801133 polymorphism were predisposed to MTX- related mucositis.

Abstract Background The numbers of confirmed cases of coronavirus disease 2019 (COVID-19) and COVID-19 related deaths are still increasing, so it is very important to determine the risk factors of COVID-19. Dyslipidemia is a common complication in patients with COVID-19, but the association of dyslipidemia with the severity and mortality of COVID-19 is still unclear. The aim of this study is to analyze the potential association of dyslipidemia with the severity and mortality of COVID-19. Methods We searched the PubMed, Embase, MEDLINE, and Cochrane Library databases for all relevant studies up to August 24, 2020. All the articles published were retrieved without language restriction. All analysis was performed using Stata 13.1 software and Mantel–Haenszel formula with fixed effects models was used to compare the differences between studies. The Newcastle Ottawa scale was used to assess the quality of the included studies. Results Twenty-eight studies involving 12,995 COVID-19 patients were included in the meta-analysis, which was consisted of 26 cohort studies and 2 case–control studies. Dyslipidemia was associated with the severity of COVID-19 (odds ratio [OR] = 1.27, 95% confidence interval [CI] 1.11–1.44, P = 0.038, I2 = 39.8%). Further, patients with dyslipidemia had a 2.13-fold increased risk of death compared to patients without dyslipidemia (95% CI 1.84–2.47, P = 0.001, I2 = 66.4%). Conclusions The results proved that dyslipidemia is associated with increased severity and mortality of COVID-19. Therefore, we should monitor blood lipids and administer active treatments in COVID-19 patients with dyslipidemia to reduce the severity and mortality.

Background. Erythema nodosum leprosum is an immune-mediated complication of leprosy whose underlying mechanism has not yet been fully elucidated, making management difficult.Objectives. To determine the serum cytokine profile of ENL compared to non-reactional leprosy states. Methods. An open literature search was performed using MEDLINE, Cochrane Library, TRIP and HERDIN electronic databases using the keywords ("cytokines" or “inflammatory mediators”) and (“erythema nodosum leprosum” or “ENL”) and (“leprosy” or “lepra”). Studies were selected by two independent review authors. Risk of bias was assessed using the Newcastle-Ottawa Scale and statistical analysis was performed using RevMan 5.3 software. Results. Eight cross-sectional studies with 197 participants were included. Meta-analysis showed that both serum IL-17 and serum IFN-γ were significantly decreased (Z 2.39, p = 0.02 and Z 2.74, p = 0.01, respectively) in ENL compared to non-reactional states. However, for IL-1β, IL-6, IL-10, IL-22, TNF-α and TGF-β, no significant differences were found between the two groups. Conlusion. ENL appears to be an exacerbation of the Th2 cytokine response seen in the lepromatous pole of leprosy. However, despite pooling of data, sample sizes remain small resulting in significant heterogeneity. Future studies involving large sample sizes and investigating a wider range of cytokines are encouraged.

Abstract Background: Polycystic ovarian syndrome (PCOS) is a kind of common gynecological endocrine disorder. And the mutations of melatonin receptor (MTNR) genes are related to the occurrence of PCOS. But previous researches have shown opposite results. So, the object of our systematic review and meta-analysis is to investigate the relationship between MTNR 1A/B polymorphisms and PCOS. Methods: PubMed, Embase, Ovid, the Cochrane Library, Web of Science and three Chinese databases (VIP, CNKI and Wanfang) were used to retrieve eligible articles published between January 1980 and February 2020. And we used the odds ratio (OR) and its 95% confidence interval (CI) to investigate the strength of the association by six genetic models, allelic, codominant (homozygous and heterozygous), dominant, recessive and superdominant models. Review Manager 5.3, IBM SPSS statistics 25 and Stata MP 16.0 software were used to do this meta-analysis. Results: Our meta-analysis involved 2553 PCOS patients and 3152 controls, for two single nucleotide polymorphisms (rs10830963 C> G in MTNR1B and rs2119882 T> C in MTNR1A) and significant associations were found in some genetic models of these single nucleotide polymorphisms (SNPs). For rs10830963, strongly significant was found in the heterozygote model (GC vs. CC, P=0.02). Additionally, a slight trend was detected in the allelic (G vs. C), homozygote (GG vs. CC) and dominant (GG+GC vs. CC) model of rs10830963 (P=0.05). And after further sensitivity analysis, a study with high heterogeneity was removed. In the allelic (P=0.000), homozygote (P=0.001), dominant (P=0.000) and recessive (GG vs. GC+CC, P=0.001) model, strong associations between rs10830963 and PCOS were found. Moreover, for rs2119882, five genetic models, allelic (C vs. T, P=0.000), codominant (the homozygote (CC vs. TT, P=0.000) and heterozygote model (CT vs. TT, P=0.02), dominant (CC + CT vs. TT, P=0.03) and recessive model (CC vs. CT + TT, P=0.000) showed significant statistical associations with PCOS. Conclusion: MTNR1B rs10830963 and MTNR1B rs2119882 polymorphisms are associated with PCOS risk. However, the above conclusions still require being confirmed by much larger multi-ethnic studies.

Abstract BACKGROUND: Mouth breathing is closely related to the facial skeletal development and malocclusion. The purpose of this systematic review and meta-analysis was to assess the effect of mouth breathing on facial skeletal development and malocclusion in children. METHODS: An electronic search in PubMed, the Cochrane Library, Medline, Web of Science, EMBASE and Sigle through February 23rd, 2020, was conducted. Methodological quality assessments of the selected articles were performed using the Newcastle-Ottawa Scale. Review Manager 5.3, was used to synthesize various parameters associated with the impact of mouth breathing on facial skeletal development and malocclusion. RESULTS: Following full-text evaluations for eligibility, 7 studies (387 mouth-breathing subjects and 433 nasal-breathing controls) were included in the final quantitative synthesis; they were all high-quality. The included indicators were SNA (p>0.050), ANS-PNS (p>0.050), 1.NB (p>0.050), MP-H (p>0.050), FMA (p>0.050), SNB (MD: -1.99, P <0.0001), ANB (MD: 0.95, P = 0.0005), SN-OP (MD: 3.20, P < 0.0001), SNGoGn (MD: 4.34, P < 0.0001), 1-NA (MD: 0.72, P = 0.004), 1. NA (MD: 1.98, P = 0.020), 1-NB (MD: 1.06, P < 0.0001), SPAS (MD: -5.23, P < 0.0001), PAS (MD: -2.11, P < 0.0001), and C3-H (MD: -1.34, P < 0.0001). CONCLUSIONS: The results showed that mouth breathing can cause underdevelopment of the mandible. The mandible rotated backward and downward, and the occlusal plane was steep. However, there was little effect on the maxilla. In addition, mouth breathing presented a tendency of lip inclination of the upper and lower anterior teeth. Airway stenosis was common in mouth-breathing children.

Abstract Background and study aim Some studies have reported an association between P2Y12 gene polymorphisms and clopidogrel adverse outcomes with inconsistent results. We aimed to explore the relationship between P2Y12 polymorphisms and the risk of adverse clinical events in patients treated with clopidogrel through a meta-analysis. Methods A systematic search of PubMed, Web of Science and the Cochrane Library was conducted. Retrieved articles were comprehensively reviewed and eligible studies were included, and the relevant data was extracted for this meta-analysis. All statistical tests were performed by the Review Manager 5.3 software. Results A total of 14 studies involving 8,698 patients were included. In the Han Chinese population, ischemic events were associated with P2Y12 T744C polymorphism in the CC vs TT+CT genetic model (OR=3.32, 95%CI=1.62-6.82, P=0.001), and the events were associated with P2Y12 C34T polymorphism in the TT+TC vs CC genetic model (OR=1.70, 95%CI=1.22-2.36, P=0.002). However, ischemic events were not related to P2Y12 G52T polymorphism (TT+TG vs GG: OR=1.13, 95%CI=0.76-1.68, P=0.56; TT vs GG+TG: OR=2.02, 95%CI=0.65-6.28, P=0.22). The associations between the P2Y12 polymorphism and ischemic events were not significant in T744C, G52T and C34T genotype for another subgroup of the Caucasian population (P>0.05). Only two studies referring to bleeding events were included in this analysis of C34T polymorphism, and no significant association was found (TT+TC vs CC: OR=1.07, 95%CI=0.37-3.15, P=0.90). Conclusions In the Caucasian population, P2Y12 gene polymorphisms are not associated with clinical events. However, in the Chinese Han population, P2Y12 T744C and C34T polymorphisms are significantly associated with adverse clinical events.

<b><i>Background:</i></b> The ovarian reserve has been reported to be diminished in patients with rheumatoid arthritis. However, these results are still controversial. Anti-Müllerian hormone (AMH) is considered a reliable biomarker for the ovarian reserve. We thus performed a meta-analysis to evaluate the AMH levels and the effect of DMARDs on the ovarian reserve in rheumatoid arthritis patients. <b><i>Methods:</i></b> PubMed, EMBASE, the Cochrane Library, and 2 Chinese databases (CNKI and Wanfang database), up to September 2021, were searched for relevant studies. The Newcastle-Ottawa scale (NOS) was used to assess the quality of the included studies. Pooled standard mean difference (SMD) with 95% confidence intervals (CIs) were determined with the random-effects model. The heterogeneity was described by <i>I</i><sup><i>2</i></sup> statistic and <i>p</i> value from the Cochrane Q test. <b><i>Results:</i></b> Eight eligible studies (679 patients and 1,460 controls) were included in the meta-analysis. Compared with healthy control, the AMH levels in RA patients were significantly lower with the pooled SMD of −0.40 (95% CI: −0.66 to −0.14). However, in comparison of AMH with and without DMARD treatment, there was no significant difference with the pooled SMD of −0.1 (95% CI: −0.39 to 0.19). <b><i>Conclusion:</i></b> The results indicated that there was an increased risk of ovarian failure in RA patients and which is not related to DMARD treatment.
