Objective To study the antibacterial performance of the fabric treated with siliconequaternary ammonium microemulsion.Methods Escherichia coli,Staphylococcus aureus and Candida albicans were used as the test bacteria and the method of bacteriostasis circle,vibration flask were used to test the effects of the antibacterial agent qualitatively and quantitatively.Results The lowest bacteriostasis concentration for siliconequaternary ammonium microemulsion was 2%,the bacteriostasis effect on staphylococcus was superior to that on E.coli and it had a good bacteriostasis effect on the yeast.Pure cotton bacteriostasis effect was most noticeable in its antibacterial reorganization and it reached 92.34% of the bacteriostasis rate after washed for 30 times,and the bacteriostasis rate for the treated fabric could still keep 99.96% after 6 months of preservation.Conclusion The fabric reorganized with the siliconequaternary ammonium microemulsion has a good capacity of bacteriostasis and washes well in antibacterial performance.

ObjectiveTo analyze the mental status of the patients with irritable bowel syndrome (IBS).MethodsSixty IBS patients were evaluated with Self Rating Anxiety Scale (SAS), Self Rating Depression Scale (SDS), Symptions Check List-90 (SCL-90) and self-edited scale.ResultsThe primary causes of mental disorder of IBS patients were the stress events and lacking knowledge for IBS; the average SAS scores of sixty IBS patients were 52.32±10.19, SDS scores were 54.90±11.70; the average scores of SAS and SDS in the groups of midlife and young people were significantly higher than that in the group of agedness ( P<0.05). The total scores of SAS and SDS were not significantly difference among the patients with different culture level and sex ( P>0.05); except the scores of crankiness and opposition, the average SCL-90 scores of the sixty IBS patients were significantly higher than the normal ( P<0.05).ConclusionIBS relates to mental status and stress, proper mental intervention can ease the symptom and improve the quality of the living.

Objective:To investigate the relationship between EGFR mutations and pulmonary tuberculosis in lung adenocarcino-ma. Methods:We detected EGFR mutations in 506 patients with lung adenocarcinoma by PCR amplification and sequencing and ana-lyzed the relationship between the mutations observed and pulmonary tuberculosis. Survival analysis was performed using the Ka-plan-Meier method with log-rank tests. Result:A total of 218 patients showed EGFR mutations;of these patients, 25 had a clinical his-tory of pulmonary tuberculosis. Compared with lung adenocarcinoma patients with no history of tuberculosis, patients with a history of pulmonary tuberculosis showed higher incidence rates of EGFR mutations, especially of exon 21 (P=0.047, P=0.002). Higher incidence rates of EGFR mutations, especially of exon 21, were observed in patients with lung cancer and tuberculosis in the same lobe or the same side of the lung than in those who had lung cancer and tuberculosis in opposite sides of the lung (P=0.02, P=0.03). Survival analy-sis showed that adenocarcinoma patients with a history of pulmonary tuberculosis have 2-year survival rates lower than that of adeno-carcinoma patients with no history of the disease (P=0.039). In patients adenocarcinoma associated with tuberculosis patients without EGFR-TKIs treatment, the 2-year survival rates of EGFR mutation patients and those without EGFR mutation showed no statistically significant difference (P=0.948). At the same time, we got the same results in adenocarcinoma associated with tuberculosis patients with EGFR-TKIs treatment (P=0.425). Conclusion:Lung adenocarcinoma patients with a history of pulmonary tuberculosis have high-er incidence rates of EGFR mutations, and EGFR mutations are not related to disease prognosis.

Objective To study CT findings and prognosis of hypoxic -ischemic encephalopathy in full term neonates .Methods Two hundred and sixty-eight cases of full-term neonates diagnosed clinically as hypoxic-ischemic enceohathy(HIE) were examined.Seventy-nine cases were observed by CT follow-up one or four times.Nineteen normal neonates with same age were selected as contral group.Results Two hundred and thirteen cases(79%)were abnormal on CT.The CT value of the low density area of brain white matter were lower than 18 HU in two hundred cases(94%).The low density area were enlarged in one hundred and ninty two cases(90%).Subarachnoid hemorrhage(SAH) were found in seven cases(3.3%) and intraventricular hemorrhage(IVH) in four cases(2%), and infarction in one case (0.5%).CT follow-up study of 51 cases were carried out around one year of age . 27 of them were abnormal on CT,mostly showing external hydrocephalus,minority of them with cerebral atrophy and softening .23 cases were studied by CT follow-up at or after two years old,3 of them had external hydrocephalus and 1 of them had cerebral softening.Conclusion CT findings of HIE mostly had :①brain edema showing lower density area of enlarged brain white matter;②brain hemorrhage mostly showing subarachnoid hemorrhage and intraventricular hemorrhage;③seldom brain infarction.Prognosis of HIE which was mild and moderate degree based on CT findings was better ,and severe degree was bad.

Objective To assess the association of single nucleotide polymorphisms ( SNPs) in SLCO1B3 gene with prognosis of breast cancer (BC) patients treated with neoadjuvant chemotherapy of TA regimen (taxane and antharcycline drugs). Methods 439 female BC patients were recruited and treated with neoadjuvant chemotherapy of TA regimen.A blood sample (2 ml) of peripheral blood was collected from each patient before chemotherapy. Tagging SNPs (tag?SNPs) were selected. We investigated the association of tag?SNPs with prognosis, by Sequenom Mass ARRAY system platform, characterizing tag?SNPs. The hazard ratio ( HR ) and 95% confidence interval ( CI ) for progression or death were calculated by multivariable?adjusted Cox regression model. Results Seven tag?SNPs ( rs11045689, rs200104106, rs3764006, rs3834935, rs4149117, rs7305323 and rs73241801) were selected for study. Compared with individuals carrying the rs11045689 GG genotype, individuals carrying rs11045689 AA genotype performed worse PFS and OS, with the HR (95% CI) for progression being 1.39 (1.11～1.75) and the HR (95% CI) for death being 1.38 ( 1.04～1.83). Compared with individuals carrying the rs73241801 CC genotype, individuals carrying rs73241801 TT genotype performed better OS (P＝0.041), with the HR (95% CI) for death being 0.65 (0.44～0.94). The number of risk allele was significantly associated with PFS (P＝0.012) and OS (P＝0.017) of BC patients by accumulation analysis. Compared with individuals carrying one or less than one risk allele, individuals carrying four risk alleles performed worse PFS and OS, with the HR (95%CI) for progression being 1.37 (1.09～1.72) and the HR ( 95% CI) for death being 1.36 (1.02～1.81). Conclusion The variations of rs11045689 and rs73241801 in SLCO1B3 gene were significantly associated with prognosis of BC patients treated with neoadjuvant chemotherapy of TA regimen, which might serve as biomarkers for predicting prognosis of BC patients treated with neoadjuvant chemotherapy.
