Objective To investigate risk factors for postoperative delirium in elderly patients with hip fractures and determine whether the delirium can influence the outcome of hip fracture.Method A retrospective case control study was performed for 521 patients (≥60 years) with hip fractures treated surgically from January 2012 to December 2014.There were 170 males and 351 females, with the age of (79.3±8.3)years.Confusion assessment method (CAM) was applied to diagnose delirium after surgery, and the subjects were divided into delirium group (n=159) and control group (n=362) according to the presence of delirium.Univariate and multivariate analyses were performed to identify the riks factors for postoperative delirium, including age, gender, comorbidities, body mass index, American Society of Anesthesiologists (ASA) classification, type of fracture, haemoglobin, PaO2, albumen, type of anesthesia, type of anesthesia, amount of bleeding, time between admission to surgery, length of operation, type of operation and amount of blood transfusion.Perioperative complications and mortality within 1 year after operation were compared between the two groups.Results Univariate analysis revealed dementia, ASA classification, haemoglobin, PaO2, albumen, interval between admission to surgery, anesthesia method, operation time, and surgery methods were risk factors for postoperative delirium incidence (P<0.05).While multivariate analysis showed only dementia (OR=6.211, 95%CI 2.482-23.498), long interval between admission to surgery (OR=3.505, 95%CI 1.478-6.342), arthroplasty (OR=2.015, 95%CI 1.783-3.481), and PaO2≤60 mmHg (OR=2.766,95%CI 1.783-5.039) were the significant risk factors for postoperative delirium after hip surgery in the elderly.Incidences of lung infection, wound infection, cardiovascular events, cerebrovascular events and deep venous thrombosis in delirium group were higher than those in control group, but only incidences of lung infection and wound infection reached significant differences (P<0.05).Mortality in delirium group was higher than that in control group within 1 year after operation, but there was significant difference only within 3 months after operation (P<0.05).Conclusions Incidence of delirium is high after hip fracture surgery in the elderly.Dementia, long interval between admission to surgery, arthroplasty and PaO2≤60 mmHg are significant risk factors for postoperative delirium incidence, and the delirium patients are associated with high early mortality.

OBJECTIVETo further explore the effect of Jiangu Erxian Pill (JGEXP) on proliferation and cell cycle of human osteoblast on the basis of previous clinical and experimental studies.

METHODSHuman primary osteoblast were isolated and cultured. The cell proliferation was tested by 3H-thymine incorporation and methyl thiazolyl tetrazolium (MMT) method and the cell cycle was determined by flow cytometry technique.

RESULTSIn the medium and high dosage JGEXP groups, the cell proliferation rate and index, and percentage of diploid synthesis phase (S phase) cells were significantly higher than those in the blank control group (P < 0.01 or P < 0.05), and similar to those in the estrogen group; and the cell apoptosis rate and percentage of G0-G1 stage cells were lower than those in the blank control group (P < 0.01 and P < 0.05).

CONCLUSIONJGEXP could effectively promote the cell proliferation and differentiation, and prevent the cell apoptosis of osteoblast in vitro.

ObjectiveTo analysis the clinical features of thoracic spine and spinal cord injury (SCI) and summarize the inclusive standard of cellular transplant clinical trial for SCI.MethodsThe data of 72 cases with thoracic spine and spinal cord injury from 1990 to 2005 were analyzed retrospectively.ResultsMean follow-up period was 20 months (6～48 months). There was no recovery in 12 spinal cord injury without radiographic abnormality (SCIWORA) patients, but improvement of urine function in 4 cases. 5 cases of 52 fracture-dislocation complete injury were improved to grade B (sense recovery), rate of recovery was 9.6%; recovery rate was 62.5% in incomplete injury. Sense recovery of all cases was better than motor recovery. Partial cases appeared spasm paralysis relief.ConclusionIncidence rate of complete injury is high and recovery is bad in thoracic spine and spinal cord injury. The inclusive standard of cellular transplant clinical trial for SCI is old complete thoracic spinal cord injury without residual compression.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

‘Program of teaching quality and teaching reform in institutions of higher education' (‘quality project' for short)is a significant measure to deepen the teaching reform of university and to improve the teaching quality of universities in a new age.The present situation of‘ quality project' system construction was analyzed and the experiences were summed up.Meanwhile the problems of emphasizing project declaring and ignoring educating,emphasizing quantity and despising feature were pointed out and the measures to promote all-round development,distinctive cultivation and coordinated management based on the needs of teachers and students were proposed.All these will future promote the development of ‘quality project' system.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.
