  • Clinical Application of Two-Port Laparoscopic Cholecystectomy

    Objective To discuss the safety,feasibility,and advantages of two-port laparoscopic cholecystectomy (LC).Methods The clinical data of 114 patients underwent LC from June 2008 to October 2010 were retrospectively analyzed,of which 46 underwent two-port LC (two-port LC group,n=46) and 68 underwent three-port LC (three-port LC group,n=68). The operation time,intraoperative blood loss,postoperative feeding time,postoperative pain,postoperative hospital stay,and hospitalization expenses were compared between two groups. Results All the operations were successful,no postoperative complications occurred in both groups.The operation time in the two-port LC group was longer than that in the three-port LC group (P<0.05). The intraoperative blood loss,postoperative feeding time,postoperative pain,and postoperative hospital stay had no significant differences in two groups (P>0.05). The hospitalization expenses in the two-port group was less than that in the three-port group(P<0.05). Conclusions Two-port LC is a safe and feasible operation in the simple gallstone patients. It is cautious in those patients with acute cholecystitis because of the restricted vision and operation.

  • Recent Progress in Individualized Therapy of Colorectal Cancer

    结直肠癌是一种严重威胁我国国民生命的恶性肿瘤,近年来其发病率呈不断上升的趋势。根据WHO报告的资料[1]显示,我国结直肠癌死亡率2005年比1991年增加70.7%,年均增加4.71%。尽管对结直肠癌的病因学研究和以手术切除、放射治疗和化学药物治疗为主的综合治疗取得了一定进展,但结直肠癌的治疗仍然面临巨大挑战。对不同个体采用相同的治疗方案不仅不能提高治疗效果,而且造成医疗资源的浪费,甚至给患者带来伤害。目前,个体差异与疗效的关系越来越受到临床医生和研究者的重视。随着循证医学的不断发展,结直肠癌的个体化治疗日益成为临床治疗及基础研究的重点。结直肠肿瘤多学科协作(multidisciplinary team,MDT)诊治模式的运用为结直肠癌个体化诊治提供了新的平台[2]。....................

  • Analysis on pain after discharged in patients with radical total gastrectomy under painless ward management

    Objective To explore the pain after discharged in patients with radical total gastrectomy under painless ward management, and to analyze the causes of pain in order to guide the treatment strategy after discharge. Methods Retrospective analysis was performed on the pain data of 82 patients who underwent radical total gastrectomy in The First Affiliated Hospital of Air Force Military Medical University from December 2015 to April 2017, and the situation of pain was followed-up at 2 weeks, 1 month, 2 months, and 3 months after discharged. Results Mild pain occurred in 25 patients at the 2 weeks after discharged; mild pain occurred in 38 patients and moderate pain occurred in7 patients at the first month after discharged; mild pain occurred in 31 patients and moderate pain occurred in 4 patients at the second month after discharged; 19 patients had mild pain at the third month after discharged. There was no significant difference in pain scores between male patients and female patients, <60 years old patients and ≥60 years old patients, patients’ operative time<180 min and patients’ operative time ≥180 min, patients’ intraoperative blood loss<200 mL and patients’ intraoperative blood loss ≥200 mL at the all time points, including the second week, the first, the second, and the third month after discharge ( P>0.05). Conclusion Painless ward management can effectively control the degree of pain in discharged patients who underwent radical total gastrectomy.

  • Study of centrifuge conditions for preparing rabbit leukocyte-poor platelet-rich plasma by single centrifugation

    Objective To explore the best centrifuge condition for preparing rabbit leukocyte-poor platelet-rich plasma (LP-PRP) by using single centrifugation method. Methods Sixteen healthy New Zealand rabbits, aged 3-4 months, were utilized in the investigation. A total of 15 mL anticoagulated blood was extracted from the central ear artery of each rabbit, with a repeat of the blood collection procedure after 1 and 2 months. The obtained blood specimens were individually subjected to centrifugation at a radius of 16.7 cm and speeds of 1 200, 1 300, 1 400, and 1 500 r/min (equivalent to centrifugal forces of 269×g, 315×g, 365×g, and 420×g) for durations of 2, 3, 4, and 5 minutes, resulting in a total of 16 groups. Following centrifugation, collect plasma from each group to a distance of 1.5 mL from the separation plane. The volumes, platelet enrichment coefficient, and platelet recovery rates of LP-PRP in each group, under varying centrifugation conditions, were methodically computed and subsequently compared. Results The volume of LP-PRP obtained under all centrifugation conditions ranged from 1.8 to 7.6 mL. At a consistent centrifugal speed, an extension of centrifugation time leaded to a significant increase in the volume of LP-PRP, accompanied by a declining trend in the platelet enrichment coefficient of LP-PRP. When centrifuged for 2 minutes, the volume of LP-PRP at speeds of 1 200 and 1 300 r/min was less than 2.0 mL, while the volume of LP-PRP obtained under other conditions was more than 2.0 mL. When centrifuged for 4 and 5 minutes, the volume of LP-PRP obtained at each speed was more than 4 mL. LP-PRP with a platelet enrichment coefficient more than 2.0 could be prepared by centrifuging at 1 200 r/min for each time group and 1 300 r/min for 2 and 3 minutes, and the highest LP-PRP platelet enrichment coefficient could be obtained by centrifugation for 2 minutes at a speed of 1 200 r/min. The platelet recovery rates of LP-PRP obtained by centrifugation at 1 200 r/min for 4 and 5 minutes, as well as centrifugation at 1 400 r/min for 5 minutes, were both greater than 60%. There was no significant difference between the groups when centrifuged at 1 200 r/min for 4 and 5 minutes (P>0.05). Conclusion In the process of preparing rabbit LP-PRP using a single centrifugation method, collecting 15 mL of blood and centrifuging at a radius of 16.7 cm and speed of 1 200 r/min for 4 minutes can prepare LP-PRP with a volume exceeding 2.0 mL, platelet enrichment coefficient exceeding 2.0, and platelet recovery rate exceeding 60%. This centrifugal condition can achieve the optimal LP-PRP action parameters in the shortest possible time.
