Bayesian network-based analysis on the influence of interaction between genes and occupational stress on hypertension in oil workers / 中国职业医学

OBJECTIVE: To analyze the effect of gene-gene and gene-occupational stress interaction on hypertension in oil workers by Bayesian network(BN) analysis. METHODS: A total of 1 233 oil workers from Xinjiang Karamay Oilfield Company were selected as research subjects by the typical sampling method. The blood pressure was measured. The polymerase chain reaction-restriction fragment length polymorphism was used to evaluate the single nucleotide polymorphism(SNP) in α-adductin(ADD1) and β_2-adrenal receptor(β_2-AR) genes. The Effort-Reward Imbalance(ERI) Questionnaire was used to evaluate the ERI model occupational stress of oil workers. BN was used to analyze gene-gene and gene-occupational stress interactions. RESULTS: The detection rate of hypertension and ERI model occupational stress of these oil workers were 25.5%(315/1 233) and 47.4%(585/1 233) respectively. The AA, AG, and GG genotype and the frequency distribution of allele A and G at ADD1 rs17833172 were statistically different in these two groups(all P<0.05). There was no statistical significance in genotypes of GG, GT and TT at Gly460Trp rs4961(P>0.05); but the difference of the frequency of G and T alleles was statistically significant(P<0.05). There was no statistical significance in genotype distribution of AA, AG and GG, and frequency distribution of A and G in β_2-AR-1023 G/A rs2053044 and+252 G/A rs1042717(all P>0.05). After controlling the confounding factors including gender, education level, marital status, smoking, alcohol drinking and body mass index, the occupational stress group had a higher risk of hypertension than the no-occupational stress group(P<0.05, the odds ratio was 1.33, the 95% confidence interval was 1.01-1.74). The directed acyclic graph constructed by BN showed that the rs17833172 and Gly460Trp rs4961 sites of the ADD1 gene was directly associated with hypertension, and the β_2-AR+252 G/A rs1042717 site was indirectly associated with hypertension because of the ADD1 rs17833172 and Gly460Trp rs4961 sites. The interaction between occupational stress and ADD1 and β_2-AR was not associated with hypertension. CONCLUSION: The incidence of hypertension in oil field workers is correlated to occupational stress, and ADD1 gene rs17833172 and Gly460Trp rs4961 polymorphism. The gene-gene interaction between β_2-AR+252 G/A rs1042717 locus and ADD1 Gly460Trp rs4961 and rs17833172 locus is associated with hypertension, while the interaction between the four loci of ADD1 and β_2-AR and occupational stress has no effect on hypertension in the oil workers.

Effect of interaction between sleep and occupational stress on the prevalence of hypertension in petroleum workers / 中国职业医学

OBJECTIVE: To explore the influence of the interaction among occupational stress, sleep duration and sleep quality on the prevalence of hypertension in petroleum workers. METHODS: A total of 3 040 workers from six oil field bases in Karamay City were selected as study subjects by multi-stage random cluster sampling method. The Chinese version of Pittsburgh Sleep Quality Scale and the revised version of Occupational Stress Scale were used to evaluate their sleep quality and occupational stress status. Binary logistic regression was used to analyze the effect of interaction of occupational stress, sleep duration and sleep quality on hypertension. RESULTS: The prevalence of hypertension in the study subjects was 15.3%(466/3 040), and the detection rates of sleep deprivation, poor sleep quality and high occupational stress were 26.5%, 78.3% and 19.6% respectively. After adjusting for confounding factors such as gender, ethnicity, age, marital status, education level, length of service, professional title, shift work, smoking, alcohol consumption and body mass index, the interaction analysis results showed that the risk of hypertension was higher in the poor sleep quality groups with normal sleep duration, sleep deprivation or longer sleep duration than that in good sleep quality group with normal sleep duration(all P<0.05), respectively. The risk of hypertension was higher in the group with sleep deprivation and high occupational stress than that in the group with normal sleep duration and low occupational stress(P<0.01). In the group with poor sleep quality and high occupational stress the risk of hypertension was higher than that in the group with good sleep quality and low occupational stress(P<0.05). CONCLUSION: The interaction among occupational stress, sleep duration and sleep quality may increase the risk of hypertension in petroleum workers.

Chinese consensus on surgical treatment of traumatic rib fractures (2021) / 中华创伤杂志

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.
