  • Clinical Comparative Study of Tension-Free Herniorrhaphy with Different Suture

    目的 观察运用两种不同缝线固定修补材料对疝修补术后的复发、切口感染、慢性疼痛等并发症发生情况。方法 对2008年4月至2010年4月期间笔者所在科室收治的250例腹股沟疝患者行无张力疝修补手术时,采用多股丝线或可吸收合成缝线固定修补材料进行前瞻性对比研究。结果 2组患者术后疝复发、切口感染和切口疼痛(包括慢性疼痛)发生率间的差异均无统计学意义(P>0.05)。结论 腹股沟疝无张力修补术后的复发、切口感染、慢性疼痛等并发症的发生与缝线选择无关。术者的操作技巧、严格的无菌操作原则、彻底止血以及组织损伤小才是防止术后感染、慢性疼痛等并发症发生的重要因素。

  • Association between obstructive sleep apnea syndrome and carotid atherosclerotic disease: a systematic review

    Objective To systematically review the correlation between obstructive sleep apnea syndrome (OSAS) and the incidence of carotid atherosclerosis. Methods PubMed, EMbase, CNKI, WanFang Data, CBM, and VIP databases were electronically searched to collect studies on the correlation between OSAS and carotid atherosclerosis and carotid intima-media thickness (CIMT) from inception to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 16.0 software and RevMan 5.3 software. Results A total of 32 studies, including 2 915 patients were included. The results of the meta-analysis showed a higher incidence of carotid atherosclerotic plaque in OSAS patients than in the control group (OR=5.56, 95%CI 0.27 to 8.38, P<0.000 01); subgroup analysis revealed that, compared with the control group, patients who were male (OR=5.38, 95%CI 2.79 to 10.38, P<0.000 01) or had mild-to-moderate OSAS (OR=3.9, 95%CI 1.66 to 9.15, P=0.002) or severe OSAS (OR=19.86, 95%CI 6.49 to 60.82, P<0.000 01) had a higher risk of carotid atherosclerosis. The CIMT of the OSAS group was significantly higher than that of the control group (SMD=1.24, 95%CI 0.97 to 1.51, P<0.000 01). There was a positive correlation between the apnea hypopnea index (AHI) and CIMT in OSAS patients (r=0.52, 95%CI 0.44 to 0.60, <0.000 1), and the CIMT increased with OSAS severity. Conclusion OSAS is associated with a high incidence of carotid atherosclerotic plaque that is highly correlated with CIMT, which increases with an increase in the AHI. These findings are required to be verified in prospective high-quality studies to overcome the limitations of quantity and quality of studies included in this systematic review.

  • Prevalence of obstructive sleep apnea syndrome in China: a meta-analysis

    ObjectiveTo systematically review the prevalence of obstructive sleep apnea syndrome (OSAS) in China. MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data, and VIP databases were electronically searched to collect cross-sectional studies of the prevalence of OSAS in China from inception to October 30th, 2020. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Meta-analysis was then performed using Stata 16.0 software. ResultsA total of 27 studies were included, with a total sample size of 97 746 cases and 10 853 confirmed OSAS patients. Meta-analysis results showed that the prevalence of OSAS in China was 11% (95%CI 5% to 17%), of which females was 12% (95%CI 5% to 19%) and males was 12% (95%CI 5% to 20%). OSAS cases grouped by regions were as follows: Central China 4% (95%CI 2.7% to 4.5%), South China 5% (95%CI 2.7% to 6.7%), North China 7% (95%CI 4.6% to 9.3%), Northeast China 22% (95%CI 17.7% to 61.2%), Southwest China 4% (95%CI 3.2% to 5%), Northwest China 16% (95%CI 14.5% to 17.7%), and East China 17% (95%CI 2.8% to 30.6%). OSAS patients grouped by ages were as follows: 4% (95%CI 3% to 5%) for ≤14 years old, 5% (95%CI 2% to 7%) for 15-44 years old, 13% (95%CI 6% to 20%) for 45-59 years old, 16% (95%CI 6% to 25%) for 60-74 years old, 13% (95%CI 4% to 23%) for 75-89 years old, and 11% (95%CI 2% to 21%) for ≥ 90 years old. A subgroup analysis based on the year of publication found that the prevalence of OSAS fluctuated between 6% and 9% from 2005 to 2020, and the prevalence was the highest from 2000 to 2005 accouted with 21% (95%CI 0.8% to 40.5%). ConclusionsThe prevalence of OSAS in China is relatively high, and there are differences in the prevalence among individuals of different ages and regions. The 60-year-old groups in addition to the Northeast and East China regions have a high incidence. The prevalence of OSAS is substantially consistent between males and females. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
