目的:观察波及黄斑区的孔源性视网膜离术后各时期黄斑区相干光断层扫描图像特征及孔源性视网膜脱离患者眼轴长度与手术后视网膜下液吸收的关系,分析其与视力恢复过程的相关性。方法:对 53例(53眼)波及黄斑区的孔源性视网膜脱离经巩膜外加压术后视网膜复位的患者分别于术后1周、1月、3月、6月进行相干光断层扫描检查,观察黄斑区形态变化及黄斑区视网膜下液残留情况,并将检查结果与患者病程、眼轴长度以及手术后视力恢复情况等临床资料进行了对比分析。 结果:术后1周,所有病例均残留程度不等的视网膜下液,随着时间的延长,积液不断吸收。与之相对应,患者视力逐渐提高。术后3月,黄斑区视网膜下积液全部吸收累计33例, 其中眼轴长度大于26 mm患者视网膜下液吸收速度较慢,差异有统计学意义(P＜0.05)。术后6月,43例患者黄斑区视网膜下积液全部吸收,仍有 7例神经上皮浅脱离,3例局限性神经上皮脱离。术后6月时患者最佳矫正视力lt;0.05者7眼,005~03者17眼,≥0.3者29眼。结论:光学相断层扫描能从微观角度清晰地显示视网膜复位后黄斑区形态结构的变化。巩膜外加压术后视网膜复位的患者黄斑区仍残留少量的视网膜下积液,视网膜下积液的逐步吸收能较好地解释术后视力的恢复过程。眼轴长度大于26mm患者视网膜下液吸收速度较慢。
Objective To collect evidence of treatment for the patients with ocular myasthenia gravis. Methods We searched The Cochrane Library (Issue 1, 2010), PubMed (1966 to April, 2010), CNKI (1979 to April, 2010) and VIP (1989 to April 2010) to identify systematic reviews, randomized controlled trials, controlled clinical trials and prospective avaicohort studies about efficacy and safety of treatment for ocular myasthenia gravis. Results We identified 2 guidelines, 5 systematic reviews and 4 observational studies on inhibitor of acetylcholinesterase, immunosuppressive agents, intravenous immunoglobulin, corticosteroids, and thymectomy for ocular myasthenia gravis. The first choice for ocular myasthenia gravis was inhibitor of acetylcholinesterase. When the symptom could not be remitted, the corticosteroids should be considered. Immunosuppressive agents might be added if the effect of corticosteroids was not good. Plasma exchange was not recommended. Thymectomy should be performed if the patients suffered from thymoma. Conclusion The best clinical evidence can be available by the evidence-based method.
Objective To explore the related factors of postoperative pulmonary infection (PPI) in patients undergoing laparoscopic colorectal cancer surgery, and analyze the perioperative management strategy of pulmonary infection combined with the concept of enhanced recovery after surgery (ERAS). Methods Total of 687 patients who underwent laparoscopic colorectal cancer surgery in the colorectal cancer professional treatment group of Gastrointestinal Surgery Center of West China Hospital of Sichuan University from January 2017 to May 2019 were retrospectively included. According to the occurrence of PPI, all the included cases were divided into infection group (n=97) and non-infection group (n=590). The related factors and prevention strategies of PPI were analyzed. Results The rate of PPI among patients underwent laparoscopic resection in our study was 14.1% (97/687). Compared with the non-infection group, the proportions of patients with preoperative complications other than cardiopulmonary, receiving preoperative neoadjuvant radiotherapy and/or chemotherapy, preoperative Eastern Cooperative Oncology Group (ECOG) score 1–2, preoperative Nutrition Risk Screening 2002 (NRS2002) score 1–3, tumor located in the left colon and rectum, combined organ resection, operative time >3 h and postoperative TNM stage Ⅱ patients in the infection group were higher (P<0.05). However, the proportions of patients who used intraoperative lung protective ventilation strategy and incision infiltration anesthesia in the infection group were lower than those in the non-infection group (P<0.05). In the infection group, the proportions of patients who received regular sputum excretion, atomization therapy, balloon blowing/breathing training, stomatology nursing after operation and postoperative analgesia were all significantly lower than those of the non-infection group (P<0.05), whereas the proportions of patients receiving antibiotics and intravenous nutrition after operation were significantly higher than those in the non-infection group (P<0.05). Logistic regression analysis showed that low preoperative NRS2002 score, intraoperative protective ventilation strategy, postoperative respiratory training, and postoperative regular sputum excretion were the protective factors of PPI, while preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor located in the left colon and rectum, late TNM staging and postoperative antibiotics were risk factors for pulmonary infection.Conclusions Preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor location in the left colon and rectum, late TNM staging and postoperative antibiotics are risk factors for pulmonary infection in patients with laparoscopic colorectal cancer. Preoperative good nutritional status, intraoperative protective ventilation strategy, postoperative respiratory training and regular sputum excretion may reduce the incidence of PPI to a certain extent.
Objective To study the effect of indirect calorimetry-guided nutritional support on energy metabolism, cellular immunity and oxidative stress in patients with colorectal cancer after laparoscopic surgery. Methods A total of 96 patients with colorectal cancer after laparoscopic surgery in our hospital from December 2019 to December 2021 were selected and randomly divided into the control group (used the formula prediction method to guide enteral nutrition support, n=48) and the observation group (used indirect calorimetry to guide enteral nutrition support, n=48). The target resting energy expenditure (REE) value and nutritional support energy intake were compared between the two groups. The cellular immune indexes (CD3+, CD4+, CD8+, CD4+/CD8+) and oxidative stress indexes [serum superoxide dismutase (SOD), malondialdehyde (MDA), the changes of glutathione peroxidase (GSH-Px)], and the changes of REE at different time points (1 day before operation and 1, 2 and 3 days after operation) of the two groups were compared. The incidence of complications in the two groups were observed. Results The target REE value of the observation group was lower than that of the control group (P＜0.05), and there was no significant difference in the enteral energy intake and parenteral energy intake compared with the control group (P＞0.05). After treatment, CD3+, CD4+ and CD4+/CD8+ in the two groups were lower than those before treatment (P<0.05), and CD8+ was higher than before treatment (P<0.05). The levels of CD3+, CD4+ and CD4+/CD8+ in the observation group after treatment were higher than those in the control group (P<0.05) , while the level of CD8+ in the observation group was lower than that in the control group (P<0.05). After treatment, the levels of SOD and GSH-Px in the two groups were lower than those before treatment (P<0.05), and the levels of MDA were higher than those before treatment (P<0.05). The levels of GSH-Px and SOD in the observation group were higher than those in the control group (P<0.05), while the level of MDA in the observation group was lower than that in the control group (P<0.05). There was no significant difference in the REE value between the two groups at 1 day before operation (P>0.05); compared with the 1 day before operation, the REE values of the two groups at 1, 2, and 3 days after operation were significantly increased, and there was a statistically significant difference between the two groups at each time point (P<0.05), but the REE value at 3 days after operation was significantly lower than that at 1 and 2 days after operation (P<0.05). The REE values in the observation group were lower than those in the control group at 1, 2 and 3 days after operation (P<0.05). The incidence of complications in the observation group was 6.25%, which was lower than 20.83% in the control group (P<0.05). Conclusion Enteral nutrition support guided by indirect calorimetry in colorectal cancer patients after laparoscopic surgery can help reduce postoperative energy consumption, improve cellular immune function and oxidative stress response, and reduce the risk of postoperative complications, which is worthy of promotion.
ObjectivesTo evaluate the reliability and validity on quality criteria for clinical nursing practice guidelines.MethodsFive appraisers were included to assess two clinical nursing practice guidelines using the quality criteria for clinical nursing practice guidelines and AGREE Ⅱ. ICC and coefficient of consistency were adopted to assess the reliability and validity of the appraisal tools.ResultsICC for two guidelines of AIDS and infusion by the quality criteria for clinical nursing practice guidelines were 0.979 and 0.890. ICC for two guidelines of AIDS and infusion by AGREE Ⅱ were 0.957 and 0.887. The coefficient of consistency for guidelines of AIDS and infusion by the two appraisal tools were 0.880 and 0.886, both were highly consistent.ConclusionsThe quality criteria for clinical nursing practice guidelines has good reliability and validity and can be used as appraisal tool for quality evaluation of clinical nursing practice guidelines. It is strongly recommended that the users should understand the appraisal tool or should be trained to decrease the bias.
ObjectivesTo systematically review the efficacy of telemedicine on blood glucose level and pregnancy outcomes in patients with gestational diabetes mellitus.MethodsThe Cochrane Library, PubMed, Web of Science, CINAHL, Scopus, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on efficacy of telemedicine on blood glucose and pregnancy outcomes in patients with gestational diabetes from inception to January 1st, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, and then meta-analysis was performed by RevMan 5.3 software.ResultsA total of 10 RCTs involving 1 267 patients were included. The results of meta-analysis showed that there were no statistical significances in fasting blood glucose (MD=−0.34, 95%CI −1.62 to 0.93, P=0.60), HbA1c (MD=−0.22, 95%CI −0.61 to 0.17, P=0.27), gestational age at delivery (MD=0.03, 95%CI −0.13 to 0.19, P=0.72), premature rate (OR=0.52, 95%CI 0.26 to 1.01, P=0.05), caesarean delivery rate (OR=0.87, 95%CI 0.57 to 1.31, P=0.51), infant birth weight (MD=13.01, 95%CI −45.75 to 71.78, P=0.66), large for gestational age rate (OR=1.16, 95%CI 0.83 to 1.62, P=0.40), pre- eclampsia/pregnancy induced hypertension rate (OR=1.04, 95%CI 0.52 to 2.09, P=0.91), neonatal hypoglycaemia rate (OR=1.21, 95%CI 0.75 to 1.95, P=0.44) and neonatal jaundice rate (OR=1.09, 95%CI 0.59 to 2.00, P=0.78) between telemedicine management and outpatient follow-up of gestational diabetes mellitus. However, the telemedicine management group had lower 2h postprandial blood glucose (MD=−3.45, 95%CI −5.53 to −1.37, P=0.001).ConclusionsThe current evidence shows that telemedicine management of gestational diabetes mellitus achieves similar efficacy and safety in blood glucose level and pregnancy outcomes as outpatient follow-up. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusions.
