目的比较腹腔镜下经腹腹膜前疝修补术与传统腹股沟疝修补术、疝环充填式无张力疝修补术治疗成人腹股沟疝的疗效。 方法选取2016年4月至2020年4月芜湖市第一人民医院收治的150例腹股沟疝患者作为研究对象,随机将其分为3组,每组50例。A组行传统腹股沟疝修补术,B组行疝环充填式无张力疝修补术,C组行腹腔镜下经腹腹膜前疝修补术。比较3组患者的临床总有效率,手术时间,出院时间,术中出血量,术后24 h、1周及1个月的疼痛视觉模拟评分（VAS）,复发率以及并发症情况。 结果B组和C组患者在临床总有效率,手术时间、出院时间、术中出血量、术后各时段的VAS评分、复发率及并发症均优于A组,差异有统计学意义（P<0.05）。B组和C组相比,C组在手术时间、住院时间、各时段VAS评分优于B组,差异有统计学意义（P<0.05）。 结论三种手术方式比较发现,腹腔镜下经腹腹膜前疝修补术与疝环填充式无张力疝修补术具有良好的临床效果,恢复迅速,可缩短住院时间,缓解术后疼痛,降低复发率和并发症发生风险,缓解了患者的疼痛,就术后疼痛、术后恢复和手术时间而言,腹腔镜下经腹腹膜前疝修补术更优越。     

预测胰十二指肠切除术后切口疝发病风险列线图模型的建立

目的建立预测胰十二指肠切除（PD）术后发生切口疝的风险列线图模型,为切口疝的早期干预提供依据。 方法回顾性分析2009年1月至2017年1月于邯郸市中心医院行PD术的926患者的临床资料,随访发生切口疝的患者24例（切口疝组）,未发生切口疝的按照1∶5的比例随机抽取120例为非切口疝组。分别使用单因素和Logistic回归多因素分析术后切口疝的独立危险因素,并建立相关列线图预测模型。 结果年龄≥60岁（OR=5.800,95% CI 1.530~21.984）、BMI≥24 kg/m²（OR=4.165,95% CI 1.187~14.613）、糖尿病（OR=5.321,95% CI 1.548~18.285）、呼吸系统疾病（OR=4.565,95% CI 1.225~17.007）、切口感染（OR=6.803,95% CI 1.573~29.419）及手术时间≥6 h（OR=6.934,95% CI 1.938~24.813）是PD术后发生切口疝的独立危险因素（P<0.05）。基于以上6项独立危险因素建立列线图模型,并对该模型进行验证,预测值同实测值基本一致,C-index 0.890（95% CI 0.854~0.926）,说明本研究列线图模型具有良好的精准度和区分度。 结论年龄≥60岁、BMI≥24 kg/m²、糖尿病、呼吸系统疾病、切口感染及手术时间≥6 h是PD术后发生切口疝的独立危险因素,本研究建立的列线图预测模型具有良好的精准性和区分度,有利于临床筛查PD术后发生切口疝的高风险人群和制定针对性规避措施。     

氧化应激反应在边缘供肝肝移植缺血-再灌注损伤中的作用研究进展

常见的边缘供肝主要包括脂肪变性供肝、高龄供肝、小体积供肝、心脏死亡器官捐献(DCD)供肝等。边缘供肝的应用可在一定程度上解决供肝数量严重短缺的问题,但边缘供肝面临着缺血-再灌注损伤(IRI)的难题,且IRI程度相比正常供肝更加严重,是导致移植失败的重要原因,其中氧化应激反应又是引起边缘供肝IRI的重要因素。因此如何减少氧化应激反应及解决边缘供肝IRI的难题成为临床研究的热点问题。活性氧簇(ROS)介导的氧化应激反应贯穿IRI整个过程,本文就氧化应激反应在边缘供肝肝移植IRI中的作用及以ROS为靶点的防治进行综述,以期为临床提供参考。

Bone Mass and Strength in School‐Age Children Exhibit Sexual Dimorphism Related to Differences in Lean Mass: The Generation R Study

Bone strength, a key determinant of fracture risk, has been shown to display clear sexual dimorphism after puberty. We sought to determine whether sex differences in bone mass and hip bone geometry as an index of strength exist in school‐age prepubertal children and the degree to which the differences are independent of body size and lean mass. We studied 3514 children whose whole‐body and hip scans were measured using the same densitometer (GE‐Lunar iDXA) at a mean age of 6.2 years. Hip dual‐energy X‐ray absorptiometry (DXA) scans underwent hip structural analyses (HSA) with derivation of bone strength indices. Sex differences in these parameters were assessed by regression models adjusted for age, height, ethnicity, weight, and lean mass fraction (LMF). Whole‐body bone mineral density (BMD) and bone mineral content (BMC) levels were 1.3% and 4.3% higher in girls after adjustment by LMF. Independent of LMF, boys had 1.5% shorter femurs, 1.9% and 2.2% narrower shaft and femoral neck with 1.6% to 3.4% thicker cortices than girls. Consequent with this geometry configuration, girls observed 6.6% higher stresses in the medial femoral neck than boys. When considering LMF, the sexual differences on the derived bone strength indices were attenuated, suggesting that differences in muscle loads may reflect an innate disadvantage in bone strength in girls, as consequence of their lower muscular acquisition. In summary, we show that bone sexual dimorphism is already present at 6 years of age, with boys having stronger bones than girls, the relation of which is influenced by body composition and likely attributable to differential adaptation to mechanical loading. Our results support the view that early life interventions (ie, increased physical activity) targeted during the pre‐ and peripubertal stages may be of high importance, particularly in girls, because before puberty onset, muscle mass is strongly associated with bone density and geometry in children. © 2015 American Society for Bone and Mineral Research.     

The efficacy of hemodialysis in interventional therapy in coronary artery disease patients with chronic renal insufficiency

The aim of this study was to explore the efficacy and safety of hemodialysis in interventional therapy for patients with coronary artery disease combined with chronic renal insufficiency. With the aging and social development, the number of coronary artery disease patients with chronic renal insufficiency gradually increased. Total 58 coronary heart disease patients with chronic renal dysfunction were selected. These patients were characterized with typical angina symptoms and typical electrocardiogram (ECG) changes of onset angina. Continuous oral administration of sodium bicarbonate tablets 1?g 3/day?×?3 days and slow intravenous input sodium chloride 1000 ～1500 mL 3–12?h before operation were given. By this way, all patients were treated by hydration and alkalization. After percutaneous coronary intervention (PCI) treatment, patients were immediately transferred to undergo 4?h of dialysis treatment without removing indwelling of femoral artery puncture sheath tube to protect renal function. Changes in renal function including serum creatinine, glomerular filtration rate, and urine were observed and recorded. All patients were successfully underwent PCI treatment. Within one month after PCI, there were no obvious complication and no stent thrombosis occurred. Among of 58 patients, 56 cases showed no significant increase in serum creatinine levels compared with those before operation. However, serum creatinine level of one patient increased to 251?umol/L and one patient still required permanent dialysis. Using hemodialysis in interventional therapy in coronary artery disease patients with chronic renal insufficiency could significantly improve the prognosis of the patients.     

A comparison of feasibility and safety of percutaneous fluoroscopic guided thoracic pedicle screws between Europeans and Asians: is there any difference?

Purpose

To directly compare the safety of fluoroscopic guided percutaneous thoracic pedicle screw placement between Caucasians and Asians.

Methods

This was a retrospective computerized tomography (CT) evaluation study of 880 fluoroscopic guided percutaneous pedicle screws. 440 screws were inserted in 73 European patients and 440 screws were inserted in 75 Asian patients. Screw perforations were classified into Grade 0: no violation; Grade 1: <2 mm perforation; Grade 2: 2–4 mm perforation; and Grade 3: >4 mm perforation. For anterior perforations, the pedicle perforations were classified into Grade 0: no violation, Grade 1: <4 mm perforation; Grade 2: 4–6 mm perforation; and Grade 3: >6 mm perforation.

Results

The inter-rater reliability was adequate with a kappa value of 0.83. The mean age of the study group was 58.3 ± 15.6 years. The indications for surgery were tumor (70.3 %), infection (18.2 %), trauma (6.8 %), osteoporotic fracture (2.7 %) and degenerative diseases (2.0 %). The overall screw perforation rate was 9.7 %, in Europeans 9.1 % and in Asians 10.2 % (p > 0.05). Grade 1 perforation rate was 8.4 %, Grade 2 was 1.2 % and Grade 3 was 0.1 % with no difference in the grade of perforations between Europeans and Asians (p > 0.05). The perforation rate was the highest in T1 (33.3 %), followed by T6 (14.5 %) and T4 (14.0 %). Majority of perforations occurred medially (43.5 %), followed by laterally (25.9 %), and anteriorly (23.5 %). There was no statistical significant difference (p > 0.05) in the perforation rates between right-sided pedicle screws and left-sided pedicle screws (R: 10.0 %, L: 9.3 %).

Conclusions

There were no statistical significant differences in the overall perforation rates, grades of perforations, direction of perforations for implantation of percutaneous thoracic pedicle screws insertion using fluoroscopic guidance between Europeans and Asians. The safety profile for this technique was comparable to the current reported perforation rates for conventional open pedicle screw technique.
