青豌豆气调包装工艺及其质量评价

摘要：包装内气氛与包装材料选择性透气性是影响果蔬气调包装质量的主要因素。对青豌豆采用6组不同初始气体组分、3种包装材料进行气调包装，在5℃，相对湿度85％的环境下贮藏7d后，测定青豌豆的相关质量指标，并与未包装产品进行比较，结果表明气调包装对青豌豆保鲜效果显著；在此基础上，用主成分分析法构造了气调包装产品质量的综合评价模型，对气调包装青豌豆质量进行综合评价，得出青豌豆气调包装的最佳初始气体组分，分析了不同包装材料对青豌豆气调包装质量的影响。

DeGarengeot hernia: transabdominal preperitoneal hernia repair and appendectomy.

BACKGROUND: The incarcerated appendix in the femoral hernia represents a rare clinical case that was first described by the Frenchman de Garengeot in 1731. Besides the open procedures, laparoscopy presented itself as a treatment option. CASE REPORT: Our case concerns a 38-year-old patient with a right femoral hernia with an inflamed incarcerated appendix. Because of the clinically inconclusive finding, we chose transperitoneal preperitoneal hernia repair (TAPP) combined with a laparoscopic appendectomy. The intra- and postoperative course was uneventful. This case shows that a laparoscopic procedure is possible even in the case of an incarceration in conjunction with an appendicitis that has not spread to the adjacent peritoneum. DISCUSSION: Compared with open interventions, the subjective social advantages (shorter hospital stay, earlier return to work, less need for pain killers, and others) of laparoscopic hernia treatment have been extensively studied. The use of both methods in the case of an incarcerated hernia is open to dispute, though various small series confirm the feasibility. CONCLUSION: Here, TAPP seems to be the more reliable method in terms of patient safety because of the simultaneous possibility of using laparoscopy.

Minimally invasive hemiarthroplasty in femoral neck fractures. Randomized comparison between a mini-incision and an ordinary incision: preliminary results

Minimally invasive osteosynthesis is a well-recognized treatment; however, those of arthroplasty or hemiarthroplasty may rarely be performed. We reviewed the comparison of a mini-incision approach in hemiarthroplasty versus that of an ordinary approach in patients with femoral neck fractures. Two different operative procedures were compared. Thirty-two patients (group 1) had a mini-incision in hemiarthroplasty. Thirty-two patients (group 2) were treated with the conventional approach. The postoperative treatment course was the same for both groups. The mean length of follow-up was 25 months. The results were excellent or good in 86% of the patients (50 of 64) and were equally good for both procedures. However, the full weight bearing term was significantly shortened for patients treated by the mini-incision procedure. Good and excellent results can be expected from either the mini-incision or the ordinary approach in hemiarthroplasty. Only full weight bearing term was significantly short following the mini-incision. This approach results in less dissection and facilitates rapid patient recovery and possibility earlier discharge from the hospital.
