Objective To explore the role of comfortable nursing in patients with malignant tumor undergoing chemotherapy and the quality of life and satisfaction degree in patients after chemotherapy. Methods 100 patients with malignant tumor undergoing chemotherapy were divided randomly into the observation group and the control group(each had 50 cases). The observation group took the comfortable nursing, the control group was applied with the traditional nursing method, their comfort degree,satisfaction degree and life quality after chemotherapy were observed and compared. Results Comparing the results of two groups of patients, the satisfaction degree of the observation group was significantly higher than the control group, the scores of life quality for the observation group and the control group were (45.2±5.1 ) and (34.1 ±4.6) respectively. Conclusions Comfortable nursing for patients with malignant tumor undergoing chemotherapy may improve their comfort degree, satisfaction degree and life quality, and hence is worthy of being recommended in clinical practice.

Objective To investigate the association between gene polymorphism of sortilinrelated receptor 1 (SORL1) and Alzheimer' s disease by detecting a series of single nucleotide polymorphisms (SNPs).Methods The Snapshot method was used to genotypc 6 SNPs (SNP10,19,23,24,25,27) in SORL1 and the distributions of allele and genotype of the 6 SNPs were compared between AD patients and healthy control individuals.Results There were significant differences in the genotype distributions of SNP19,23,24 and 25 between AD patients and control group (all P＜0.01).Subjects with TT genotype in SNP19 had significantly lower risk for AD and was protective for AD (OR=0.089,95％CI:0.011-0.718,P＜0.01).The AT genotype in SNP23 (OR＝3.826,95％CI:1.388～10.544,P＜0.01),CT genotype in SNP24(OR=5.935,95％CI:1.774-19.853,P＜0.01)and CT genotype in SNP25(OR=5.754,95％CI:2.007-16.496,P＜0.01)had higher risks for AD.Conclusions SORL1 gene variants of SNP19,23,24 and 25 might be the important risk factors for late-onset AD.

OBJECTIVE To study infection status and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) in the female genital tract.METHODS The retrospective analysis of identification and the antimicrobial susceptibility testing of mycoplasma in 2263 female cervical secretions from Jan 2007 to Jun 2008 were conducted.RESULTS In 2263 cases,the positive rate of mycoplasma was 66.46%.The infection only by Uu accounted for 45.03%,by Mh for 1.46%,and the mixed infection for 19.97%.The results of drug sensibility test showed that drug resistances of mycoplasma were diffirent among three types of mycoplasma infections.CONCLUSIONS The infectious rate of mycoplasma from female cervical secretions is on big rise.It is important to culture and test the drug sensitivities of mycoplasma for choosing drugs rationally and control the resistant strains.

Objective To investigate the effect of hypertriglyceridemic waist(HTWC)phenotype on cognitive function in patients with type 2 diabetes.Methods According to the standard of plasma triglycerides concentration≥1.7 mmoL/L,waist circumference(WC)≥ 90 cm in men or ≥80 cm in women,304 patients with type 2 diabetes were divided into four groups:normal triglycerides and waist circumference group(group A,n =65),normal waist circumference and hypertriglyceridemia group (group B,n=53),abdominal obesity and normal triglycerides group(group C,n=114),and HTWC group(group D,n =72)for prospective studies.Patients in four groups were surveyed with Mini-mental state examination (MMSE)and Montreal cognitive assessment (MOCA).And changes of cognitive function among the four groups were compared.Results Total score for the MMSE was significantly lower in group D than in group A(27.1±1.9 vs.29.0±1.3,F=2.869,P=0.019).The subscales of attention and calculation(4.0± 1.4 vs.4.6±0.9,F=1.605,P=0.047)and recall(2.2± 0.9 vs.2.6±0.6,F=1.959,P=0.043) were significantly lower in group D than in group A.Total score for the MOCA was significantly lower in group D than in group A(23.4±3.9 vs.25.9±3.6,F =1.975,P=0.031).The subscales of visuospatial and executive(3.5 ± 1.4 vs.4.1 ± 0.9,F=1.537,P =0.048),attention(5.1±1.4 vs.5.7±0.9,F=1.660,P=0.048)and orientation(5.6±1.0 vs.6.0± 0.0,F=2.362,P=0.030)were significantly lower in group D than in group A.Conclusions There is a statistically more significant decline in cognitive function in patients with HTWC phenotype and the effective intervention and treatment are needed.

Objective To observe any influence of hyperbaric oxygen (HBO) treatment on the formation of glial scars,and to explore how HBO suppresses the inflammatory reaction to injury.Methods A total of 96 healthy,adult,male,Sprague-Dawley rats were used to model cerebral puncture injury.They were then randomized into a control group and a treatment group,with 48 rats in each group.The treatment group received HBO treatment,while the control group received no special treatment.At 1,3,7,14 and 28 days after the puncture injury,the rats' right brain tissues were harvested and immunohistochemical staining was employed to compare the changes in number of astrocytes and microglial cells around the injury in the two groups.The level of tumor necrosis factor α (TNF-α) and interleukin 1 β (IL-1β) in the cerebral tissue was examined using ELISA.Results Among the control group the average wound areas after 7,14 and 28 days were (2.73 ± 0.05)μm2,(3.42 ± 0.18)μm2 and (2.41 ± 0.09) μm2,a significant reduction after 28 days compared with 7 and 14 days.The corresponding average wound areas of rats in the treatment group were (2.78±0.12)μm2,(2.59 ±0.08)μm2 and (1.20 ±0.06)μm2.There the average wound area had decreased significantly after 14 days,and the further reduction after 28 days was also significant.The numbers of GFAP-positive astrocytes at 14 and 28 days had increased significantly compared with after 7 days in both the control group and the treatment group.The average number of GFAP-positive astrocytes in the control group at 28 days had decreased significantly compared with after 14 days.Compared with the control group at the same time points,the number of GFAP-positivc astrocytes in the treatment group was significantly less.After modeling,the number of ionized calcium-binding adapter molecule Ⅰ (Ibal)-positive microglial cells increased significantly,but there was a significant decrease in both the control and treatment groups by 7 days.The average number of Ibal-positive microglial cells in the treatment group was significantly less than in the control group at all of the time points.Compared with the first day after modeling,the TNF-α concentration of the controls at 3 and 7 days was significantly higher,but by the 7th day it was significantly lower than it had been after 3 days.The average IL-1β concentration in the control group and TNF-α concentration in the treatment group had increased by day 3,but then decreased by day 7.The IL-1β concentration of the treatment group declined gradually.The average TNF-α and IL-1 β concentrations of the treatment group were significantly lower than those of the control group at all of the time points.Conclusion HBO treatment has a relatively good curative effect on cerebral puncture injury.It can accelerate wound healing and reduce the formation of glial scars.Its mechanism could be related to the deactivation of astrocytes and microglia cells and reducing the levels of cell factors that promote inflammation.

Objective To study any protection against hippocampal neuron damage induced by epilepsy (SE) provided by transcutaneous stimulation (TNS) of the trigeminal nerve and to document any effect of such stimulation on the expression of glutamic acid decarboxylase (GAD) 65/67.Methods Pilocarpine injection was used to induce epilepsy in healthy male Sprague-Dawley rats which were then randomly divided into a treatment group and a model group.Rats which had not received the pilocarpine injection served as normal controls.In the treatment group the rats were given electrostimulation for one month after the first spontaneous seizure following the injection of pilocarpine.In the model group they were given sham TNS for one month.After the month of stimula-tion,immunohistochemistry was used to detect the expression of GAD65/67 in the hippocampus.Terminal deoxy-nucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assays and Nissl staining were applied to deter-mine apoptosis and neuron loss in the hippocampus.Results Significantly less apoptosis was observed in the treatment group than in model group at 24 h,48 h and 72 h post-injection.Compared to the model group,average GAD65/67 expression had increased significantly in the treatment group at 24 h,72 h,1 week,2 weeks and 4 weeks post-stimulation.GAD65 expression reached its peak from 72 h to 1 week post-stimulation,then decreased to the level of the control group by 4 weeks post-stimulation.The expression of GAD67 remained elevated at all the time points employed.Conclusions TNS can significantly protect hippocampal neurons from damage in epilepsy,at least in rats.The underlying anti-epileptic and neuroprotective mechanisms may involve increased inhibitory transmission induced by the stimulation.

Objective To analyze the genetic characteristics and the evolution of the influenza A (H3N2) virus strains circulating in Jiangsu province between 2013 and 2014.Methods This study analyzed thirty-one representative strains of influenza A (H3N2) virus, which were isolated in different regions of Jiangsu province and during different time periods from 2013 to 2014.Results Genetic distances in nucleic acid and amino acid between a strain used for vaccine production (A/Texas/50/2012) and the 31 strains were 0.010 5 and 0.012 4.Similarities between them in nucleic acid and amino acid sequences were 97.9%-99.6% and 97.2%-99.3%.Phylogenetic analysis showed that the hemagglutinin (HA) genes of the 31 strains were divided into three different groups.Three strains isolated in 2013 and three strains isolated in 2014 belonged to Group 1 and Group 2, respectively, while the others belonged to Group 3.Three positive selection sites (237, 366 and 367) in HA protein were observed by REL model.Compared with the strain used for vaccine production, the 31 strains were characterized by amino acid substitutions (N128A/T and P198S/A) in HA protein and all of the mutations located in B-cell epitopes.The total number of mutation sites reached 24.Compared with the A/Texas/50/2012 strain, seven strains presented the glycosylation site 126NWT, and three strains showed disappeared glycosylation sites of 45NSS and 144NNS.Evaluation of vaccine efficacy for A(H3N2) virus strains showed that the vaccine efficacy was not very well.Conclusion The HA gene of A(H3N2) virus had undergone a greater variation and the vaccine efficacy was not very well in Jiangsu province during 2013 to 2014, which made the influenza A(H3N2) virus become the circulating strain.
