Objective To determine the safety and efficacy of surgical biliary bypass on the elderly patients with unresectable pancreatic head cancer. Methods The clinical data of 55 cases with unresectable pancreatic head cancer treated with palliation methods from July 2002 to June 2009 in our hospital were retrospectively analyzed. The patients were divided into three groups according to different age and therapeutic program: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (group A), 19 patients under 65 years of age were treated by surgical biliary bypass (group B) and 17 patients with the age of 65 years or older received percutaneous transhepatic biliary drainage (group C). Then the therapeutic results were compared.Results With respect to the postoperative level of serum bilirubin, the incidence of early complications, postoperative hospitalization and mean survival time, no statistically significant difference was found between group A and B (Pgt;0.05). There was one case of recurrent jaundice and one case of gastric output obstruction in group B, while no one suffered postoperative complication in group A, and the difference was statistically significant (Plt;0.01). Compared with group A, the postoperative level of serum bilirubin, the number of patient readmitted, the rate of recurrent jaundice and gastric output obstruction were higher in group C (Plt;0.05 or Plt;0.01). The mean postoperative hospitalization and overall survival time were significantly shorter in group C than group A (Plt;0.05 or Plt;0.01, respectively). Conclusion Surgical palliation does not increase the morbidity rate, but it does improve the quality of life in elderly patients with unresectable pancreatic head cancer.
Objective To identify an evidence-based treatment for an elderly patient with intertrochanteric fractures. Methods Clinical problems were presented on the basis of the patient’s conditions, and evidence was collected from the NGC (2000 to 2009), The Cochrane Library (Issue 4, 2009), TRIP Database, PubMed (1966 to 2009) and CBM (1978 to 2009). Treating strategies were formulated in terms of the three-combination principle (best evidence, the doctor’s professional knowledge and the patient’s desire). Results Three guidelines and sixteen studies were included. The current evidence indicated that surgery was the preferred solution to intertrochanteric fractures of the elderly patient. The sliding hip screw (SHS) appeared superior to others. There was insufficient evidence to support the routine use of closed suction drainage in orthopedic surgeries. Early surgery was associated with shorter hospital stay and improved mortality. Antibiotic prophylaxis significantly reduced infections. In order to lower the risk of venous thromboembolism, pharmacological prophylaxis should be carried out when the patient was admitted to hospital and be assisted with mechanical prophylaxis after surgery. Nutritional supplementation was conducive to the recovery of the patient. Rehabilitation ought to be performed as soon as possible. Considering the patient’s condition, the treatment option was established according to the available evidence and guidelines. Short-term follow-up showed a good outcome. Conclusion Through the evidence-based method, an individual treatment plan could obviously improve the treatment effect and prognosis.
慢性阻塞性肺疾病( COPD) 在全球的患病率和死亡率均高居不下, 并有不断增长的趋势, 由此带来了沉重的经济和社会负担。2011 年《COPD 诊断、管理和预防的全球策略》( 以下简称“GOLD 策略”) 更新内容中, 将COPD 定义为一种可防可治的常见疾病, 以持续性气流受限为特征[ 1] 。气流受限呈进行性发展, 伴有气道和肺对有害颗粒或气体所致慢性炎症反应的增加。急性加重和合并症影响患者整体疾病的严重程度。此外, 2011 版GOLD 策略还更新了疾病评价标准, 不再简单地根据气流受限分级治疗, 而是提出整合了患者临床症状、气流受限程度以及急性加重风险等三方面综合评估的概念[ 1 ] 。同时指出, 对于高风险患者, 无论临床症状多少, 吸入糖皮质激素 ( ICS) 与长效β2 受体激动剂( LABA) 联合治疗是 GOLD 策略推荐的首选治疗方案之一。支持这一建议的一个重要或里程碑式的循证医学证据就是“迈向COPD 患者健康的变革 ( TORCH) ”的研究[ 2 ] 。该研究从研究设计、研究主要结果、研究结果的亚组分析及影响因素等多方面进行了详细的分析, 并相继在众多国际著名医学杂志发表了16 篇文章[ 2-1 7] , 成绩斐然, 对COPD 防治策略的制订产生了非常积极的影响。认真分析和借鉴TORCH 研究及其后续分析带给我们的启示, 对提升今后疾病的临床研究质量、发掘研究成果、促进 COPD 的防治等方面将有积极的意义。
Objective To investigate the effect of the serum from severe burn patients on the biology characteristics of human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro, so as to explore the feasibility of hUCMSCs transplantation for treating severe burn. Methods The 3rd passage of hUCMSCs were randomly divided into 3 groups: 10% fetal bovine serum group (group A), 10% normal serum group (group B), and 10% burn serum group (group C). At 24 hours, 72 hours, and 6 days after culture, the cell morphology and density were observed by inverted microscope; the cell proliferation was assessed by MTT; after 6 days of culture, the cell cycle by propidium iodide staining and flow cytometry, the apoptosis by acridine orange/ethidium bromide staining, and the cell senescence by β-galactosidase staining; the levels of tumor necrosis factor α (TNF-α), interleukin 1 (IL-1), platelet-derived growth factor (PDGF), and insulin-like growth factor 1 (IGF-1) in serum were detected by a double-antibody sandwich ELISA kit. Results hUCMSCs were long spindle/polygon in 3 groups. The cell fusion of group C was obviously faster than that in group A and group B. The cell proliferation curves showed that the velocity and number of cell proliferation in group C were significantly higher than those in group A and group B at 2-6 days after culture (P lt; 0.05). The rates of proliferation period (S) of hUCMSCs were 9.21% ± 1.02%, 11.79% ± 1.87%, and 20.54% ± 2.03%, respectively in groups A, B, and C at 6 days, and group C was significantly higher than that of group A and group B (P lt; 0.05). The hUCMSCs showed normal morphology and structure in 3 groups, and no apoptosis cells was observed. The positive cells percentage of group C (2.6% ± 0.1%) was significantly lower than that of group A (4.8% ± 0.2%) and group B (3.8% ± 0.4%) (P lt; 0.05). The levels of TNF-α, IL-1, PDGF, and IGF-1 in group C were significantly higher than those in group B (P lt; 0.05). Conclusion The higher levels of cytokines in serum from the severe burn patients can significantly stimulate hUCMSCs proliferation, prevent cells apoptosis, and reduce cells senescence. Therefore, it is feasible to use hUCMSCs transplantation for treating severe burn patients.
Objective To integrate the falling experience and coping styles of stroke home patients with falls through Meta synthesis, summarize existing problems based on the integration results, and propose suggestions. Methods We searched databases including PubMed, Medline, Embase, Web of Science, etc., from database establishment to January 2023, to collect qualitative studies on stroke patients’ falling experience at home. The quality of included studies was evaluated by “JBI Australian Evidence-based Health Care Centre (2008) Qualitative Research Quality Assessment Criteria”. The results were integrated by integrating methods. Results A total of 6 references were included, and 18 clear research results were extracted. Similar results were summarized and combined to form 6 new categories, and integrated into 3 main themes. The integration results showed that stroke patients with falls had severe psychological problems, poor coping styles, and unmet needs for fall prevention, resulting in reduced social participation and exercise. Conclusions It is necessary to improve the content of fall assessment and provide corresponding fall prevention health education based on the assessment results. It helps stroke patients and caregivers at home to establish correct coping strategies, thereby avoiding the occurrence of falls.
Objective To explore the application effect of process optimization in perioperative venous access management. Methods A total of 205 general surgery patients in the Operating Room of Cheng Du Shang Jin Nan Fu Hospital, West China Hospital of Sichuan University from April to May 2018 were selected as the control group, and 205 general surgery patients from June to August 2018 were selected as the observation group. The traditional management process was used in the control group, and the process optimization management was performed in the observation group. The establishment of venous access and related complications between the two groups of patients, as well as the satisfaction of patients and staff before and after the process optimization were compared. Results There was no significant difference in gender, age, education level, operation type, anesthesia method, operation duration, or intraoperative intravenous infusion channels between the two groups of patients (P>0.05). There was no statistically significant difference in gender, age, educational background, job title, job nature, or working years of the staff participating in the satisfaction survey before and after the process optimization (P>0.05). The rate of repetitive venous puncture (15.61% vs. 58.05%) and the idelness ratio of the intraoperative indwelling needle approach (10.73% vs. 52.20%) in the observation group were lower than those of the control group, and the differences were statistically significant (P<0.05). There was no statistically significant difference in the incidence of tube blockage, detubation, or phlebitis/exudation between the two groups (P>0.05). After process optimization, patient satisfaction (22.91±3.43 vs. 17.44±4.90) and staff satisfaction (28.17±2.56 vs. 20.65±3.71) were higher than before optimization, and the differences were statistically significant (P<0.05). Conclusions The process optimization of venous access management for perioperative patients can effectively reduce the rate of venous repeated venipuncture and the idelness ratio of the intraoperative indwelling needle approach, reduce invasive operations on patients, reduce the ineffective work of nurses, avoid the waste of medical resources such as manpower and materials, and improve the satisfaction of patients and staff. It is worthy of promotion and application.
ObjectiveTo compare the complications and clinical scores of posterior lumbar intervertebral fusion (PLIF) in middle-aged and older patients of different ages, and to assess the risk of complications of PLIF in different ages, providing a reference for clinical treatment.MethodsThe clinical data of 1 136 patients, who were more than 55 years old and underwent PLIF between June 2013 and June 2016, were retrospectively analyzed. According to the age of patients undergoing surgery, they were divided into 3 groups as 55-64 years old, 65-74 years old, and ≥75 years old. The general characteristics, comorbidities, and surgical data of the three groups were compared, with comparison the morbidity of complications. According to the minimal clinical important difference (MCID), the improvement of patient’s pain visual analogue scale (VAS) score and the Oswestry disability index (ODI) score were compared. Univariate logistic regression analysis was used to analyze the difference of complications and the improvement of VAS and ODI scores. Multivariate logistic regression analysis was performed for the risk factors of complications.ResultsThere were significant differences in the number of surgical fusion segments and osteoporosis between groups (P<0.05); there was no significant difference in gender, body mass index, operation time, preoperative American Society of Anesthesiologists (ASA) classification, and comorbidities between groups (P>0.05). All patients were followed up 6-62 months with an average of 27.4 months. Among the results of postoperative complications, there were significant differences in the total incidence of intraoperative complications, systemic complications, minor complications, and the percentage of improvement of ODI score to MCID between groups (P<0.05); but there was no significant difference in the total incidence of complications at the end of long-term follow-up and the percentage of improvement of VAS score to MCID between groups (P>0.05). Univariate logistic regression analysis showed that after adjusting the confounding factors, there were significant differences in intraoperative complications and the percentage of improvement of ODI score to MCID between 55-64 and 65-74 years old groups (P<0.05); systemic complications, minor complications, complications at the end of long-term follow-up, and the percentage of improvement of ODI score to MCID in ≥75 years old group were significantly different from those in the other two groups (P<0.05). Multivariate logistic regression analysis showed that age was a risk factor for systemic complications, minor complications, and complications at the end of long-term follow-up. Except for age, long operation time was a risk factor for intraoperative complications, increased number of fusion segments was a risk factor for systemic complications, the number of comorbidities was a risk factor for minor complications, and osteoporosis was a risk factor for complications at the end of long-term follow-up.ConclusionThe risk of surgical complications is higher in the elderly patients (≥75 years) with lumbar degenerative diseases than in the middle-aged and older patients (<75 years), while the improvements of postoperative VAS and ODI scores were similar. Under the premise of fully assessing surgical indications, PLIF has a positive effect on improving the elderly patients’ quality of life.
