Objective:To systematically evaluate the relationship between rs1012068 and rs5998152 single nucleotide polymorphisms of DEPDC5 gene and susceptibility to hepatocellular carcinoma (HCC).Methods:Up to October 31, 2022, PubMed, Embase, Scopus, Web of Science and China National Knowledge Internet (CNKI) were used to search the relationship between rs1012068, rs5998152 and susceptibility to HCC. The odds ratio (OR) values and 95% CI of the five genetic models were calculated, and the RevMan5.3 software was used for meta analysis. Results:A total of 12 articles were included in this study, including 11 articles about rs1012068 locus, including 2 609 patients with HCC and 8 171 controls, and 3 articles about rs5998152 locus, including 411 patients with HCC and 1 448 controls. The results of meta analysis showed that among the five genetic models of rs1012068 locus, allele pattern (G vs T: P=0.02), dominant pattern (GG+ TG vs TT: P=0.01) and heterozygote pattern (TG vs TT: P=0.009) were significantly different between the case group and the control group. In homozygous mode (GG vs TT: P=0.05) and recessive mode (GG vs TG+ TT: P=0.08), there was no correlation between rs1012068 gene polymorphism and susceptibility to HCC. Among the five genetic models of rs5998152 locus, allele model (C vs T: P=0.03), dominant model (CC+ TC vs TT: P=0.001) and heterozygous model (TC vs TT: P<0.000 01) were significantly different between case group and control group. There was no correlation between rs5998152 gene polymorphism and susceptibility to HCC in recessive model (CC vs TC+ TT: P=0.31) and homozygous model (CC vs TT: P=0.09). Conclusions:There is a correlation between rs1012068 locus and susceptibility to HCC in allele model and dominant gene model, which is a genetic factor promoting tumorigenesis. The allele pattern, dominance pattern and heterozygote pattern of rs5998152 locus can increase the risk of liver cancer, but no correlation was found in other patterns.

Objective:To observe the susceptibility factors of elderly patients with corynebacterium striata in sputum of lower respiratory tract and analyze its clinical therapeutic effect.Methods:The clinical data of 192 elderly inpatients infected with corynebacterium striatum detected in sputum of lower respiratory tract were retrospectively analyzed in Quanzhou First Hospital Affiliated to Fujian Medical University from January 2019 to June 2021.The detection rate of corynebacterium striata was calculated, and the susceptibility factors and clinical efficacy were compared between the infection group(n=102)and the colonization group(n=90).Results:The detection rate of corynebacterium striata(detected cases / numbers of qualified lower respiratory tract sputum specimen)was 0.8%(72/8976)from January to December 2019, 2.3%(134/5877)from January to December 2020, and 3.0%(121/4 039)from January to June 2021, the difference was statistically significant( χ2=93.93, P<0.01). The detection rates of corynebacterium striatum during three corresponding periods in elderly patients were 0.6%(57/8 976), 1.4%(81/5 877)and 1.9%(78/4 039), respectively, with statistically significant differences( χ2=45.57, P<0.01). The incidences or values of following indexes were higher in infection group than in colonization group: age of patients, admission of intensive care unit, malnutrition, use of hormones, combined use of antibiotics, use of invasive mechanical ventilation, use of fiber bronchoscope, reduced cough reflex, other basic diseases, and so on, but the differences were not statistically significant(all P>0.05). The clinical effective rates were 41.2%(42/102)in the infection group and 48.9%(44/90)in the colonization group, respectively, and the differences was not statistically significant( P>0.05). Only 25 patients(24.5%)in the infected group were treated on corynebacterium striatum according to drug sensitivity results.Among them, the clinical effective rate of the treatment group and the untreated group was 68.0%(17/25)and 32.5%(25/77), respectively, the difference was statistically significant( χ2=9.84, P<0.01). The clinical effective rate of untreated group was lower than that of colonization group, the difference was statistically significant( χ2=4.62, P<0.05). Conclusions:The detection rate of corynebacterium striatum in elderly patients is high, and increases year by year.Patients infected with corynebacterium striatum usually has a variety of susceptibility factors, if not taking effective treatment measures, may have adverse outcomes.In clinical work, it is necessary to pay attention to and reduce the susceptibility factors of corynebacterium striatum, and to correctly interpret the etiological reports, so as to adopt a reasonable and effective therapeutic schedule.

Correlation analysis between ATM gene polymorphism and susceptibility of sporadic breast cancer / 中国医师杂志

Objective:To analyze the relationship between ataxia telangiectasia mutated (ATM) single nucleotide polymorphism (SNP) at rs1801516 and rs1800054 and sporadic breast cancer (SBC) in Inner Mongolia.Methods:A total of 102 patients with SBC (72 Han and 30 Mongolian) who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from January 2018 to September 2019 were prospectively collected as case group and 102 healthy women (72 Han and 30 Mongolian) during the same period as control group. 2 ml of venous blood was collected to extract DNA. According to the Single Nucleotide Polymorphism Database (dbSNP), the highly polymorphic sites rs1801516 and rs1800054 of ATM gene were selected. The polymerase chain reaction (PCR) and direct sequencing were used to detect the polymorphism of the two sites, and the correlation between the single nucleotide polymorphism of the two sites and the susceptibility of SBC in Inner Mongolia was analyzed. The potential association between clinicopathological factors and ATM gene polymorphism in patients with SBC in Inner Mongolia were explored.Results:GG, GA and AA genotypes were detected in rs1801516 locus of ATM gene. Only CC genotype was detected in the rs1800054 locus of ATM gene. There was no significant difference in the distribution of genotype frequency and allele frequency between Mongolian breast cancer group and Han breast cancer group, Mongolian control group and Han control group, Mongolian breast cancer group and Mongolian control group, Han breast cancer group and Han control group (all P>0.05). Logistic regression analysis showed that allele G was the susceptibility gene of SBC in Inner Mongolia ( OR: 1.775, 95% CI: 1.04-3.03, P=0.04). ATM rs1801516 polymorphism may be associated with increased risk of breast cancer in patients with mass diameter ≤2 cm and/or without lymph node metastasis (all P<0.05). Conclusions:The polymorphism of ATM gene rs1801516 and rs1800054 may not be significantly correlated with the risk of SBC in Inner Mongolia. The rs1801516 locus may be associated with increased risk of breast cancer in patients with mass diameter ≤2 cm and/or without lymph node metastasis. Gene G may be one of the susceptible genes of SBC in Inner Mongolia.

Association of CYP2J2 polymorphism with susceptibility to psoriasis in Turkish population: a case-control study

Abstract Background: Cytochrome P450 2J2 is mostly expressed in extrahepatic tissues; it metabolizes arachidonic acid to epoxyeicosatrienoic acids, with various cardio protective and anti-inflammatory effects. CYP2J2 polymorphism has been identified as a risk factor for cardiovascular diseases, but its association with psoriasis remains unknown. Objective: To evaluate CYP2J2 polymorphism as a risk factor for psoriasis in the Turkish population. Methods: There were 94 patients with psoriasis and 100 age- and sex-matched healthy controls included in the study. Detailed demographic and clinical characteristics were recorded, and Psoriasis Area and Severity Index (PASI) scores were calculated for psoriasis patients. Venous blood samples were collected from all the participants and CYP2J2 50G>T (rs890293) polymorphism was analyzed using polymerase chain reaction (PCR). Results: Both T allele and TT + GT genotype frequencies were increased in psoriasis vulgaris patients compared to the control group (p = 0.024 and p = 0.029 respectively, OR = 2.82, 95% CI: 1.11-7.15) No association between CYP2J2 polymorphism and clinical features of psoriasis was identified. Study limitations: A limited number of patients were included in the study. Conclusion: CYP2J2 50G>T (rs890293) polymorphism was associated with an increased risk for PsV in the Turkish population.

Advance in the studies of the bidirectional effects of corona virus disease 2019 and cardiovascular disease / 解放军医学杂志

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), similar to severe acute respiratory syndrome (SARS) coronavirus, can bind to angiotensin converting enzyme 2 (ACE2) receptor, damage multiple organs and is more contagious. Clinical studies have found that patients with cardiovascular disease are more susceptible to coronavirus disease 2019 (COVID-19), and are more prone to develop severe disease after infection and have a poor prognosis. Since patients with cardiovascular disease have more ACE2 receptors, are more prone to vascular endothelial damage, while patients with COVID often have increased plasma angiotensin II and inflammatory factors, hypoxia in body and myocardium, and blood coagulation dysfunction, so that the overall disease aggravated. At present, there is insufficient research on the specific mechanism of the interaction between COVID and cardiovascular disease (especially the mechanism of increased susceptibility to COVID in patients with cardiovascular disease). In present paper, the characteristics of the SARS-CoV-2, the susceptibility, and the concurrent characteristics of the underlying diseases are discussed, which provides reference suggestions for the next clinical and experimental steps.

Detection of the risk signals of drug-induced liver injury: Challenges and advances / 临床肝胆病杂志

Early detection and effective monitoring of the risk signals of drug-induced liver injury (DILI) are of great importance in the prevention and management of DILI in clinical practice. However, the lack of high sensitivity and strong specificity in the detection of risk signals brings great challenges to the identification and monitoring of risk signals and causes difficulties in establishing the strategies for the prevention and control of DILI. This article analyzes the challenges in the identification of DILI risk signals, summarizes the applicability and limitations of risk signals based on commonly used indices in early recognition, prediction, and early warning of DILI, proposes an identification and monitoring model for DILI risk signals based on specific biomarkers, and elaborates on their potential clinical values, so as to provide a scientific basis for developing targeted strategies for the prevention and control of the risk of DILI.

Objective To explore whether tumor necrosis factor receptor-associated protein 1 (TRAP1)gene copy number variation was associated with susceptibility and clinical characteristics of systemic lupus erythematosus (SLE).Methods The study enrolled 304 SLE patients and 391 healthy controls.They were used to investigate the association between TRAP1 gene copy number variation and SLE susceptibility.Then,304 SLE patients were divided into copy number=2 group and copy number＞2 group to study the association between TRAP1 gene copy number variation and disease activity or clinical characteristics of SLE.AccuCopyTM Kit was used to detect the TRAP1 gene copy number.Data analyses were performed by SPSS 10.01 software.The suitable method was selected among t test,rank sum test and x2 test for analysis based on the data type and distribution,univariate and multivariate logistic regression analysis were performed to investigate the associ-ation between TRAP1 gene copy number variation and susceptibility and clinical characteristics of SLE.Results The copy number variation of TRAP1 gene showed an association with the susceptibility to SLE crude OR=5.257,95％CI (1.108,24.937),P=0.037;the adjusted OR=5.578,95％CI (1.172,26.556),P=0.031].There was no association between TRAP1 gene copy number variation and SLE disease activity index (SLEDAI) score (Z=-0.117,P=0.907).The copy number variation of TRAP1 gene had a marginal association with skin lesions in SLE [OR=0.130,95％CI (0.016,1.069),P=0.058],but it disappeared after adjusting for potential confounders [OR=0.288,95％CI (0.029,2.831),P=0.286,PBH=0.808].There was no correlation between TRAP1 gene copy number variation and arthritis,alopecia,oral ulcers,fever,hematologic disorder,lupus nephritis as well as photosensitivity in SLE [x2=0.751,OR=1.234,95％CI (0.767,1.988),P=0.386].No multiplicative interaction was found between TRAP1 gene copy number variation and age or body mass index (BMI) [age:x2=0.751,OR=1.234,95％CI (0.767,1.988),P=0.386;BMI:x2=0.282,OR=1.172,95％CI(0.652,2.109),P=0.596].Conclusions The copy number variation of TRAP1 gene may be associated with susceptibility to SLE.Increased TRAP1 gene copy number may be a risk factor for SLE.

Correlation between GenoType MTBDRplus Assay and Phenotypic Susceptibility Test for Prothionamide in Patients with Genotypic Isoniazid Resistance / 결핵

BACKGROUND: The purpose of this study was to analyze the relationship between the gene mutation patterns by the GenoType MTBDRplus (MTBDRplus) assay and the phenotypic drug susceptibility test (pDST) results of isoniazid (INH) and prothionamide (Pto). METHODS: A total of 206 patients whose MTBDRplus assay results revealed katG or inhA mutations were enrolled in the study. The pDST results were compared to mutation patterns on the MTBDRplus assay. RESULTS: The katG and inhA mutations were identified in 68.0% and 35.0% of patients, respectively. Among the 134 isolated katG mutations, three (2.2%), 127 (94.8%) and 11 (8.2%) were phenotypically resistant to low-level INH, high-level INH, and Pto, respectively. Among the 66 isolated inhA mutations, 34 (51.5%), 18 (27.3%) and 21 (31.8%) were phenotypically resistant to low-level INH, high-level INH, and Pto, respectively. Of the 34 phenotypic Pto resistant isolates, 21 (61.8%), 11 (32.4%), and two (5.9%) had inhA, katG, and both gene mutations. CONCLUSION: It is noted that Pto may still be selected as one of the appropriate multidrug-resistant tuberculosis regimen, although inhA mutation is detected by the MTBDRplus assay until pDST confirms a Pto resistance. The reporting of detailed mutation patterns of the MTBDRplus assay may be important for clinical practice, rather than simply presenting resistance or susceptibility test results.

X-linked Toll-like receptor 7 polymorphism associated with susceptibility to Chikungunya Fever

Objective: To investigate the association between TLR3 and TLR7 polymorphisms with susceptibility and clinical manifestations of Chikungunya Fever. Methods: A total of 177 individuals were studied: 73 patients with a confirmed diagnosis for Chikungunya virus and 104 non-infected individuals. Polymorphisms were determined by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Results: Our analysis showed an increased CC genotype frequency of the TLR7 rs3853839 polymorphism in male patients compared to control (29% versus 2%, respectively; OR=20.69; 95 % CI= 2.55-167.36; P<0.001). Furthermore, arthritis (acute and chronic) was frequently found in CC male patients. On the contrary, 65% of CG carriers were no-infected males (29% versus 65%, respectively; OR=0.23, 95% CI=0.48-3.04; P=0.002). Finally, we observed a higher frequency of lymphopenia in CG male patients (CG=666.86±233.77, GG=1,314.27±752.29 cells/mm3, P=0.047). Conclusions: Our results suggest the TLR7 rs3853839 polymorphism is associated with lymphopenia and increased susceptibility to Chikungunya Fever in males.

Objective To investigate the relationship between the rs6682925T / C gene polymorphism of interleukin (IL)-23 receptor (IL-23R) gene and susceptibility to acute coronary syndrome (ACS). Methods A case-control study. 180 ACS patients (the disease group) and 90 patients with normal coronary angiography(control group) were selected from January 2017 to April 2018 in jingzhou central hospital. The disease group included 109 males and 71 females,aged (59.95±9.29) years old and the control group included 49 males and 41 females, aged (58.39 ± 9.43) years old. The gene polymorphism of IL-23R gene rs6682925T/C was detected by Sanger sequencing,and serum IL-23R concentration in peripheral blood was detected by ELISA. The statistical analysis methods used include normal distribution test,t test,analysis of variance and chi-square (χ2) test. Unconditional logistic regression analysis of the relationship between IL-23R gene rs6682925T/C polymorphism and susceptibility to ACS. Results There were no significant differences in gender, age, body mass index, apolipoprotein b, total cholesterol and low-density lipoprotein cholesterol between the ACS group and the control group(χ2=0.923, P>0.05;t=1.294, P>0.05;t=-0.574, P>0.05; t=- 0.417, P>0.05). However, the differences in triglyceride, fasting blood glucose, high-density lipoprotein cholesterol,smoking rate,diabetes and hypertension were statistically significant(t=5.411,P<0.05;t=5.828, P<0.05;t=-6.655, P<0.05;χ2=7.738, P<0.05;χ2=13.201, P<0.05;χ2=8.359, P<0.05). Compared with the control group, the IL-23R rs6682925 polymorphic site in ACS group had significant differences in the distribution of TT, CT, CC genotype and C allele frequency (χ2=9.858, P<0.05;χ2=10.833, P<0.05) and the frequency of C allele in the acute coronary syndrome group was significantly higher than that of the control group. In addition, the risk of rs6682925 CC genotype carriers suffer from acute coronary syndrome was 3.261 times that of TT genotype (95％CI:1.553-6.847,P=0.002). Compared with the control group,the serum IL-23R concentration in the peripheral blood of the ACS group was significantly increased [(353.20±140.79) pg/ml vs (187.41±123.36) pg/ml,t=9.495,P<0.01]. Conclusions IL-23R rs6682925 gene polymorphism is associated with genetic susceptibility to ACS, and the rs6682925 CC genotype might act as a risk factor for ACS.

An adverse intrauterine environment due to preeclampsia can not only lead to premature birth,low birth weight and fetal intrauterine distress,but also have long-term impacts on the fetus,such as increasing their susceptibility to metabolic,cardiovascular and neurological disorders.It also increases the risk of preeclampsia in female offspring.Researches focusing on the long-term effects of preeclampsia on the future generation is helpful to understand the pathophysiological mechanism of preeclampsia and to provide timely interventions in early life to reduce the occurrence of chronic diseases in later life.

X-linked Toll-like receptor 7 polymorphism associated with susceptibility to Chikungunya Fever

Objective: To investigate the association between TLR3 and TLR7 polymorphisms with susceptibility and clinical manifestations of Chikungunya Fever. Methods: A total of 177 individuals were studied: 73 patients with a confirmed diagnosis for Chikungunya virus and 104 non-infected individuals. Polymorphisms were determined by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Results: Our analysis showed an increased CC genotype frequency of the TLR7 rs3853839 polymorphism in male patients compared to control (29% versus 2%, respectively; OR=20.69; 95 % CI= 2.55-167.36; P<0.001). Furthermore, arthritis (acute and chronic) was frequently found in CC male patients. On the contrary, 65% of CG carriers were no-infected males (29% versus 65%, respectively; OR=0.23, 95% CI=0.48-3.04; P=0.002). Finally, we observed a higher frequency of lymphopenia in CG male patients (CG=666.86±233.77, GG=1,314.27±752.29 cells/mm3, P=0.047). Conclusions: Our results suggest the TLR7 rs3853839 polymorphism is associated with lymphopenia and increased susceptibility to Chikungunya Fever in males.

Emotional stress-induced Shanghuo syndrome increases disease susceptibility / 中国中药杂志

Shanghuo(excessive internal heat) is a special organic state based on the concept of traditional Chinese medicine(TCM), commonly known as the abnormal heating syndrome of body in folks. With the acceleration of modern life rhythm and the increase of the social competition pressure, emotional stress has become an important cause for the spread of Shanghuo symptoms. What's more, Shanghuo can impact the body physiological functions to cause the onset, recurrence and progression of common diseases, harming the health of the body. According to the long-term research findings, the author found that Shanghuo referred to the imbalance of multiple physiological functions, such as nerve, immunity and metabolism, caused by emotional stress. "Shanghuo" is not a disease itself, but it can increase the susceptibility to a variety of diseases. This study reviewed the traditional medicine theory and the modern medical studies, and explored the relevance and correlation mechanisms between the Shanghuo symptoms and disease susceptibility, so as to provide a reference to improve the state of sub-health and prevent or treat modern diseases.

Association between nucleotide excision repair cross-complementing gene polymorphism and susceptibility to endemic arsenic poisoning / 中华地方病学杂志

Objective To investigate the relationship between nucleotide excision repair cross-complementing (ERCC) gene polymorphisms [single nucleotide polymorphism (SNP) sites: rs11615, rs13181, rs238406, rs6498486, rs17655] and susceptibility to endemic arsenic poisoning. Methods The study recruited 848 subjects, including 348 cases and 500 controls, from populations exposed to high arsenic levels through drinking water in northwest China, and 3 - 5 ml venous blood was collected. The genotypes were determined using polymerase chain reaction and restriction fragment length polymorphism techniques(PCR-RFLP). Logistic regression analysis was used to assess the association of genotypes with endemic arsenic poisoning. Results The polymorphisms of rs11615 (ERCC1), rs238406 (ERCC2), rs6498486 (ERCC4) and rs17655 (ERCC5) and endemic arsenic poisoning were not related(P > 0.05). Participants who carried the CC genotype or at least one C allele for the ERCC2 rs13181 had an increased risk of endemic arsenic poisoning[OR(95%CI)=1.63(1.13,2.34),1.64(1.14,2.34)]compared with wild type homozygous individuals. Conculsions There is no positive correlation between the polymorphisms of ERCC1 rs11615, ERCC2 rs238406, ERCC4 rs6498486, ERCC5 rs17655 and endemic arsenic poisoning. ERCC2 rs13181 polymorphism increases the risk of endemic arsenic poisoning.
