Objective To explore the relationship between postoperative cancer-related fatigue and nutritional risk in patients with colorectal cancer. Method Using convenience sampling method, 159 postoperative colorectal cancer patients were interviewed with cancer-related fatigue scale and PG-SGA 7 days after operation. Results The average score of CRF was (21.28 ± 6.06). The score by PG-SGA was (15.18 ± 5.55). About 94.34%patients were in need of nutritional intervention. The postoperative cancer-related fatigue was positively related to PG-SGA scores(all P<0.05). Conclusions The postoperative colorectal cancer patients are at a high risk of malnutrition, with nutrition risk positively related with somatic cancer-related fatigue. The clinical nursing staff should pay attention to the nutritional status of patients and correct their malnutrition so as to reduce the symptoms of cancer-related fatigue.

ObjectiveTo compare the health-related quality of life (HRQOL) of patients with or without coronary artery disease (CAD) and also to determine the factors affecting their quality of life.MethodsOne hundred patients with CAD and 100 patients without CAD were included in this cross-sectional study. The patients with CAD and the patients without CAD were matched by age, sex, marital status, and income. HRQOL was measured with the generic HRQOL instrument.ResultsHRQOL scores of the patients with CAD differed significantly from the patients without CAD. Compared to the patients without CAD, the HRQOL of the patients with CAD was lower in the dimensions of mobility, hearing, breathing, elimination, usual activities, mental function, discomfort and symptoms, vitality, and sexual activity. The patients with CAD had lower HRQOLscores than the patients without CAD. In the patients with CAD, age and sex independently affected the HRQOL. Older patients and women had worse HRQOL.ConclusionCoronary artery disease negatively affects HRQOL. It is thought that interventions to increase quality of life the patients with CAD may improve their HRQOL.

Objective To explore influence of out-hospital health education on life quality of senile patient with acute myocardial infarction (AMI) after underwent stenting therapy of coronary artery.Methods A total of 100 cases of AMI patients undergoing stenting therapy of coronary artery were selected and randomly divided into the follow-up group and control group with 50 cases in each group. Patients of the follow-up group accepted out-hospital health education. While patients of the control group were only carried out conventional in-hospital health education. The quality of life of two groups was compared.Results At the end of study, the follow-up group had a better life quality than the control group ( P<0.01). The satisfactory degrees of nurse-patient relationship in the follow-up group were better than that of control group ( P<0.05).Conclusion Out-hospital health education can improve life quality of senile patient with AMI after underwent stenting therapy of coronary artery.

Objective To investigate the epidemiological characteristics and therapeutic strategies of patients infected with hepatitis C virus (HCV)genotype 6 in Guangxi area.Methods Serum samples were collected from 150 patients with serologic HCV RNA positive in Guangxi, China. Reverse transcription nested polymerase chain reaction (PCR)was employed to amplify HCV NS5B fragments and the DNA products were sequenced.The sequences obtained were compared with the sequences deposited in GenBank to construct a phylogenetic tree.Among the patients who accomplished 48-week treatment of interferon plus ribavirin and 24-week follow-up after stopping medication,10 cases were infected with genotype 6a and 28 cases with genotype 1 HCV.The virological responses were evaluated at week 4,week 12,week 24 of treatment and week 24 after the end of the treatment.Results Among all recruited 150 cases,21 (14.0%)cases were HCV genotype 6 including two subtypes 6a (n = 20 )and 6d (n = 1 ). Genotype 6 HCV mainly affected intravenous drug users, especially with age of ≤ 40 years old. Phylogenetic tree showed that there was very close evolutionary distance between HCV 6 strains of Guangxi and Hongkong,China strains (Y12083,DQ 480515)and Vietnam strain (EU246930).All of 10 HCV genotype 6a patients who completed 48 weeks of antiviral therapy achieved sustained virological response (SVR).The rate of SVR was higher than that of genotype 1 patients,but without statistically different significance (10/10 vs 75 .0%,P >0.05).Conclusion HCV genotype 6 in Guangxi area mainly affects young intravenous drug users with age of ≤ 40 years old,which has high homology with Hongkong,China and Vietnam standard strains.Patients with HCV 6 genotype infection treated with interferon plus ribavirin for 48 weeks usually achieve favorable SVR.

Objective To investigate the protective effect of hypoxia-inducible factor-1α(HIF-1 α) on the neurovascular unit in rats with traumatic brain injury (TBI).Methods The fluid percussion model was applied to induce TBI in rats.A total of 600 rats were divided into sham operation group,TBI group,TBI + HIF-1 α silence group and TBI + control virus group according to the random number table,with 150 rats in each.Virus-mediated HIF-1 α silence gene and control virus were delivered 24 h before the fluid percussion injury.After 3,7 and 14 d,brain injury area and morphological changes in injured region were detected by HE staining,expressions of vascular endothelial cell markers (vWF) and HIF-1 α were detected by Western blot method,and expressions of vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9),tumor necrosis factor-α (TNF-α),interleukin 6 (IL-6) and nuclear factor-κB (NF-κB) in peripheral blood and brain tissue were detected by ELISA method.Rat neural function was dynamically assessed using the modified neurological severity score (mNSS).Results (1) Brain injury area and edema area in TBI + HIF-1 α silence group were higher than those in TBI group at all time points (P ＜ 0.05).(2) Compared with sham operation group and TBI + control virus group,expression of HIF-1α in TBI group gradually increased and remained high at 7 and 14 d postinjury (P ＜ 0.05).Compared with TBI group,expression of vWF in TBI + HIF-1αsilence group decreased at all time points (P ＜ 0.05) and inhibited angiogenesis.(3) TBI + HIF-lα silence group versus TBI group showed remarkably decreased VEGF at all time points,increased expressions of TNF-α,IL-6 and NF-κB at all time point,and increased expression of MMP-9 at 7 and 14 d postinjury (all P ＜0.05).(4) TBI + HIF-1α silence group versus TBI group showed significant difference in mNSS at 7 and 14 d postinjury (all P ＜ 0.05).Conclusions After TBI,high expression of HIF-1αcan facilitate vascular formation and inhibit inflammatory reaction related factor expression,inducing the mitigation of brain edema and brain injury.Therefore,promoting HIF-1α expression may become a new means to improvement of neurovascular function after TBI.

Objective To study the effect of simvastatin (SIM) on the expression of neuron specific enoalse (NSE) in rat brain and serum after traumatic brain injury (TBI), and therapeutic effects of SIM on TBI thereof. Methods A total of 90 Sprague-Dwalye (SD) rats aged 8 weeks were randomly divided into sham TBI group, control group and treatment group (n=30). The TBI model was established in control group and treatment group by using Feeney method. Rats in treatment group were fed SIM 10 mg/kg in the evening pre-injury and in every evening post-injury while those in control group were fed the same dose of starch at the same time. Blood samples (3 mL) were collected from carotid atrery in three groups, then rats were sacrificed and brains were collected at different time points (3 h, 12 h, 24 h, 3 d, 7 d and 14 d post-injury). The serum ex-pressions of NSE were detected by ELISA method. The NSE expressions in hippocampal area CA3 were detected with immu-nohistochemistry. Results (1) In control group, the serum NSE level was significantly increased at 3 h after injury, reached the peak at 3 d, and was still higher than that of sham injury group at 14 d. In treatment group, the serum NSE level was in-creased 3 h after injury, reached the peak at 24 h, decreased after 3 d, and was near the sham injury group at 14 d after inju-ry, but was significantly lower than that of control group. (2) Immunohistochemical detection showed that the NSE optical density values in hippocampal area CA3 area were decreased at 3 h after injury in control group. The optical density values reached the lowest level between 3 d to 7 d and were still significantly lower than those of sham injury group at 14 d. In treat-ment group the optical density value was decreased at 3 h after injury, reached the lowest level between 12 h to 24 h and re-bounded significantly at 7 d, then at 14 d up to the level of sham injury group. Conclusion SIM can promote the decrease of serum NSE level in TBI rats and increase the NSE expression of hippocampal neurons of injured side, showing protective effects on neuronal damage after traumatic brain injury.

Objective To evaluate the clinical efficacy of universal self-locking anatomical plate for acetabulum and pelvis (USAPAP) in the treatment of posterior acetabular fractures.Methods Data of 55 patients with posterior acetabular fractures who were treated with the USAPAP from January 2014 to January 2016 were retrospectively analyzed.There were 39 males and 16 females with an average age of 38.5 years old (range,17-82 years).There were 35 fractures on the left side while the other 20 fractures were on the right side,including 52 fresh cases and 3 old cases.According to Letournel-Judet classification,there were 32 cases of posterior wall,9 cases of transverse and posterior wall,5 cases of anterior column and posterior wall,2 cases of posterior column,2 cases of transverse,2 cases of two columns,1 case of anterior column and posterior hemitransverse,2 cases of Pipkin type Ⅳ.All patients were managed operatively by the USAPAP,which allows simultaneous fixation for two columns and quadrilateral surface fractures through a single Kocher-Langenback approach.The quality of reduction was assessed by Matta's score system.The mean follow-up period was 18.5 months (range,12-24 months).Average operation time was 95 min,and average blood loss was 350 ml.Average operation time of plate and screws fixation was 19 min,and average fluoroscopy times in the surgery was 2 times.The mean time of bony union was 4.3 months.According to the criteria described by Matta,the excellent and good rate of radiological score was 92.7％ (51/55),including 39 cases excellent,12 cases good and 4 cases poor.The excellent and good rate of Merle d'Aubigne-Postel score was 87.3％ (48/55),including 35 cases of excellent,13 cases of good,5 cases of fair,and 2 cases of poor.Heterotopic ossification occurred in 1 patient (Brooker type Ⅱ) at three months postoperatively.One case with Pipkin type Ⅳ fracture underwent total hip arthroplasty due to femoral head necrosis at seven months postoperatively.Complications including wound infection,sciatic nerve injury,screw invade joint,redisplacement of the fracture,avascular necrosis of bone fragment,hardware failure,nonunion or malunion was not found in any case at the latest follow-up.Conclusion The USAPAP through the single posterior Kocher-Langenback approach provides strong and stable fixation for complex acetabular fractures associated with posterior region including posterior wall,both columns and quadrilateral surface.Satisfactory clinical results can be achieved by the use of this method.

Objective Through the establishment of adjacent cabin blast injury model of Beagle dog,to investigate the pathophysiological changes in the experimental animals in this scenario,then speculate on the mechanisms of injury.Methods Several adjacent cabins were built in the same size with the real warship.Seven Beagle dogs were subjected to injuries from the explosion,from whom one was selected randomly to implant intracranial pressure transducers before blast,the others were tested on the pathophysiological changes after blast.The dogs were mounted on the platform of a cabinet in the adjacent cabin,subjected to injury from 650g bare TNT explosive blast.The transducers recorded the value of space and intracranial shock wave pressure.Following blast treatment,the serum levels of IL-6,IL-8,neuron specific enolase (NSE),brain and chest CT and pathological changes of the brain tissue were observed.Results Serum levels of IL-6,IL-8 and NSE were elevated to varying degrees after blast.All of them increased significantly at different time points after blast (P＜0.05).Brain and chest CT examinations did not show any significant positive results.Pathological results showed that there was a little necrosis in the brain,some neurons had karyopycnosis,karyolysis or disappearance of the nucleoli,and the cell boundaries were blurred.The blast wave was blocked greatly by the scalp and skull (about 90％),but could still penetrate them and cause brain injuries.Conclusions Explosion in the adjacent cabin causes mainly mild traumatic brain injuries.Blast wave can be blocked by the scalp and skull greatly.
