加味十全大补汤对老年股骨粗隆间骨折患者术后隐性失血及血糖水平的影响

目的:探讨加味十全大补汤对老年股骨粗隆间骨折患者术后隐性失血及血糖水平的影响。方法:选取120例老年股骨粗隆间骨折患者,随机分为两组,各60例。两组均行防旋型股骨近端髓内钉(PFNA),对照组术前不予以药物治疗,观察组术前3 d予以加味十全大补汤。统计两组住院时间、骨折愈合时间,对比术前、术后1 d、3 d、7 d血红蛋白(Hb)、红细胞比容(Hct)水平、隐性失血量、空腹血糖水平,并于术后6个月随访,观察髋关节恢复情况。结果:术后1 d、3 d、7 d,观察组Hb、Hct水平高于对照组(P<0.05)。观察组术后1～3 d、3～7 d隐性失血量分别为(245.74±88.26)ml、(188.26±70.12)ml,均少于对照组(288.67±90.94)ml、(245.94±75.36)ml(P<0.05)。术后1 d、3 d、7 d,观察组空腹血糖水平分别为(7.74±0.76)mmol/L、(6.26±0.52)mmol/L、(5.12±0.46)mmol/L均低于对照组(9.67±0.84)mmol/L、(7.94±0.66)mmol/L、(6.48±0.52)mmol/L(P<0.05)。观察组骨折愈合时间、住院时间短于对照组(P<0.05)。术后6个月随访,观察组髋关节功能恢复优良率91.38%与对照组84.21%,组间比较差异无统计学意义(P>0.05)。结论:加味十全大补汤治疗老年股骨粗隆间骨折患者,可纠正贫血,减少隐性失血量,加快骨折愈合,缩短住院时间,且对血糖水平影响较小。     

Association between head and neck cancer and sexually transmitted diseases: a Danish nationwide,case-control study

Abstract

Background: An association between sexually transmitted diseases (STDs) and occurrence of head and neck cancer (HNC) is proposed.

Aims/objectives: We aimed to determine the association between selected STDs (syphilis, gonorrhoea, HIV) and HNC.

Materials and methods: Patients diagnosed with HNC in Denmark between 1978 and 2014 identified through the Danish Cancer Registry were included. Patients were age- and sex-matched in a 1:10 ratio with general population controls. Uni- and multivariate analyses were performed using the Cox regression model to assess the correlation between STD and HNC.

Results: A total of 39,405 HNC patients (63% men; 63.0 years at HNC diagnosis) and 393,238 controls were included. STD in HNC patients was 0.27%, vs. 0.11% in controls. Patients with cancer of the upper airways had a significantly higher prevalence of an STD prior to the HNC compared to controls. Most HNC patients with a prior STD (64.1%) developed the HNC within five years after the STD diagnosis.

Conclusions: Although the studied STDs are rare, patients with cancer of the upper aerodigestive tract more commonly had a previous diagnosis of STD compared to controls. The study promotes the hypothesis that a causal link exists between STD and HNC.     

Survival Rate and Application Number of Total Hip Arthroplasty in Patients With Femoral Neck Fracture: An Analysis of Clinical Studies and National Arthroplasty Registers

BackgroundTotal hip arthroplasty (THA) is an increasingly popular treatment option for fractured neck of femur (NOF). The primary aim of this study is to systematically review all literature on primary THA and hemiarthroplasty (HA) after fractured NOF to calculate an overall revision rate. Furthermore, we wanted to compare primary THA implantations after fractured NOF between different countries in terms of THA number per inhabitant.MethodsAll clinical studies on THA and HA for femoral neck fractures between 1999 and 2019 were reviewed and evaluated with a special interest on revision rate. Revision rate was calculated as “revision per 100 component years.” THA registers were compared between different countries with respect to the number of primary implantations per inhabitant.ResultsTHA studies showed a mean revision rate of 11.8% after 10 years, which was lower than a 24.6% 10-year revision rate for HA. We identified 8 arthroplasty registers that revealed an annual average incidence of THA for fractured NOF of 9.7 per 100,000 inhabitants.ConclusionThis study showed that patients with THA were less likely to be revised at 10 years compared to HA. We found similar annual numbers of THAs for fractured NOF per inhabitant across countries. The results of this analysis can be used to rank present and future national THA numbers within an international context.     

Profiles of immune cell infiltration and their clinical significance in head and neck squamous cell carcinoma

It is well established that there exist comprehensive interactions between tumor immunology and tumor biology. Tumor-infiltrating immune cells (TIICs) have been appealing therapeutic targets due to their significance in regulating cancer progression. The purpose of this study was to illustrate the comprehensive landscape of TIICs composition in head and neck squamous cell carcinoma (HNSCC) and their clinical significance. CIBERSORT was applied to calculate the 22 immune cell types proportion in HNSCC and further analysis suggested that six kinds of immune cells (resting memory CD4 T cells, M1 macrophages, resting dendritic cells, resting mast cells, monocytes, and eosinophils) were closely correlated with HNSCC progression. Moreover, memory CD4 T cells may serve as prognosis indicator for HNSCC patients. Collectively, this study uncovered the immune cells infiltration landscape in HNSCC and illustrated their potential relationships with clinical parameters, thereby contributing to the development of customized treatment strategy.     

Arg399Gln XRCC1 Polymorphism and Risk of Squamous Cell Carcinoma of the Head and Neck in Jordanian Patients

Background and objective: X-ray repair cross-complementing group1 (XRCC1) is a key protein in base excision repair and closely associated with the coordination of the base excision repair pathway. Many studies have focused on XRCC1 SNPs and have shown an associated between these SNPs and the risk of several types of cancers, including head and neck cancer. There are many single nucleotide polymorphisms XRCC1 gene (SNPs) and the most common SNP that result in amino acid substitutions is exon 10 (Arg399Gln). This study aimed to investigate the association between Arg399Gln SNP and the risk of squamous cell carcinoma of the head and neck. Material and method: Ninety nine patients with squamous cell carcinomas of the head and neck and 89 healthy adult controls were enrolled in this study. The Arg399Gln in XRCC1 allele was genotyped using polymerase chain reaction-restriction fragment length polymorphism method. Results: In the single-locus analyses, Arg399Gln SNP showed a significant association with head and neck cancer risk (p value = 0.016 and odd ratio of 1.8). On the genotype level, we applied three analysis models, namely co-dominant, dominant, and recessive genotypes. Arg/Arg homozygous major genotype was significantly (p value <0.05) associated with head and neck squamous cell carcinoma incidence with odd ratio of 2.23 and 2.24 for the co-dominant and recessive models, respectively. Conclusion: The findings indicated that Arg399Gln allele was associated with squamous cell carcinoma of the head and neck among Jordanian patients. This allele might be used as a genetic biomarker of squamous cell carcinoma of the head and neck.
