Objective To understand the status of catheter-related bloodstream infection in Respiratory Intensive Care Unit (RICU),and explore the effect of catheter record in the prevention of catheter-related bloodstream infection (CRBSI) in RICU.Methods A quasi-experimental study was used in the study.The patients with the central venous catheters in the Respiratory Intensive Care Unit of Grade Ⅲ hospital in Beijing were enrolled.The control group was given normal care,and the intervention group was given catheter record and other nursing intervention.The infection rate of CRBSI was compared between two groups after intervention.Results Ninety-four patients were completed date collection,43 patients were in intervention group and 51patients were in control group.The infection of CRBSI was five cases (9.8％) in the control group,and 0 case in the intervention group,and the difference was statistically significant (x2 =4.453,P ＜ 0.05).The thousand-day-infection rate of CRBSI was 0.00 in the intervention group,and 4.36‰ in the control group.The catheter logs which were completely recorded were 31 (72％),and the catheter logs which were not completely recorded were 12 (28％).Conclusions A serious of nursing intervention measures including setting up catheter record,aseptic operation and pipeline observation and maintenance can decrease the infection rate of CRBSI.

OBJECTIVETo investigate the association between single nucleotide polymorphisms (SNPs) of the complement component 3 gene (C3) and adult asthma of Hans in southern China.

METHODSA case-control study was performed. Four hundred and eighty-four adult asthma patients diagnosed in Nanfang Hospital and Affiliated Hospital of Guangdong Medical College, and 553 healthy subjects were collected from 2006 to 2010 for the study. MassARRAY-IPLEX and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) techniques was used to determine the genotypes of the rs10402876 and rs366510 loci of C3 gene.

RESULTSGenotypes GG, GT and TT in the rs366510 locus, and genotypes GG, GT and TT in the rs10402876 locus were detected. A total of 98.94 percent of samples were genotyped. There were no significant differences in genotype frequencies (chi-square =0.346,P=0.841) and allele frequencies (chi-square =0.101,P=0.751) of rs10402876 between the two groups. However, genotype and allele frequencies of the rs366510 locus were significantly different (chi-square =9.759, P=0.008, Bonferroni correction, P=0.016; chi-square =5.294,P=0.021, Bonferroni correction, P=0.042, respectively). Compared with genotypes GG+GT, genotype TT of rs366510 significantly increased the risk of asthma, with the odds ratio of 1.471 (95% confidence interval 1.125-1.923).

CONCLUSIONThese results suggest that C3 gene could be associated with adult asthma of Han population in southern China.

OBJECTIVETo explore the relationship between polymorphisms of FAS and FASL genes and genetic susceptibility of silicosis.

METHODSA case-control study was conducted. The case group was 183 male patients with silicosis and the control group was 111 male silica-exposed but without silicosis miners. Data on total dust concentrations was collected to estimate cumulative total dust exposure (CTE) of each subject and each person's characteristics and work history were obtained from questionnaire. Polymerase chain reaction re-strained fragment length polymorphism technique (PCR-RFLP) was applied to detect the single nucleotide polymorphisms (SNPs) of FAS-1377, FAS-670 and FASL-844. Associations between polymorphisms and risk of silicosis and stages, interactions between polymorphisms, between polymorphisms and CTE and smoking and haplotypes were analyzed.

RESULTSThere were no differences in the FAS-1377, FAS-670 and FASL-844 genotypes between the case group and the control group (P > 0.05). No association was observed between FAS-1377, FAS-670 and FASL-844 polymorphisms and silicosis and stages (P > 0.05). The frequencies of FAS-1377G/-670G haplotype in the cases (9.6%) were higher than those in the controls (3.6%) (P < 0.05). No interactions between the polymorphisms of different genes, the gene polymorphism and the total accumulative total dust, the gene polymorphism and smoking were observed (P > 0.05).

CONCLUSIONFAS-1377, FAS-670 and FASL-844 polymorphisms are not susceptible factors of silicosis. The FAS-1377G/-670G haplotype might be a susceptibility marker of silicosis.

OBJECTIVEGlycogen debranching enzyme (AGL) plays an important role in complete degradation of the glycogen, and has two independent catalytic activities, i.e., those of alpha-1, 4-glucanotransferase (EC 2.4. 1.25) and amylo-1,6-glucosidase (EC 3.2. 1.33). A deficiency in activities of AGL causes excessive accumulation of glycogen with short branched outer chains and results in glycogen storage disease type III (GSD III; MIM #232 400), an autosomal recessive inborn disorder of glycogen metabolism. The present study aimed to investigate the mutation of AGL in 10 Chinese patients with GSD III.

METHODClinical and laboratory data of 10 patients with typical clinical manifestations of GSD III suggesting hypoglycemia, hyperlipidemia, increased creatine-phosphokinase and its isozyme were collected. The coding regions and their flanking introns of AGL gene of the 10 patients were amplified by PCR and analyzed by direct DNA sequencing. All the mutated alleles were confirmed by bidirectional DNA sequencing. The 3 novel splicing mutations were analyzed by restriction fragment length polymorphism (RFLP) in 50 healthy children (control). The 2 small deletions (c.408-411delTTTG, c.2717-2721delAGATC) were analyzed by fluorescent polymerase chain reaction and gene scan analysis to confirm the number of deleted bases.

RESULTThirteen different mutations were identified, including 4 splicing mutations (IVS6 + 1G > A, IVS6-1G > A, IVS14 + 1G > T, IVS26-2A > C), 5 nonsense mutations (R469X, R864X, S929X, R977X, Y1428X), 3 small deletions (c.408-411delTTTG, c.2717-2721delAGATC, c.2823delT) and 1 insert mutation (c.4234insT). Except for IVS14 + 1G > T, R864X, and R977X, the other 10 mutations are novel; 18 mutated alleles were identified in the 20 alleles (90%). IVS14 + 1G > T was the most frequently seen mutation, accounting for 5 of 20 (25%) alleles examined. None of homozygote and heterozygote of the 3 novel splicing mutations was found in the 50 healthy controls by RFLP analysis. With the fluorescent polymerase chain reaction and gene scan analysis, c.408411deTTTG mutation and c.2717-2721delAGATC mutation were confirmed to have 4 and 5 bases deletion respectively.

CONCLUSIONThirteen mutations were identified in the 10 cases with GSD III, with 10 novel mutations. IVS14 + 1G > T was a relatively common mutation. This study revealed the heterozygosity of AGL gene in Chinese patients with GSD III.

Objective: To analyze the survival of newly diagnosed malignant tumors in cancer registration areas of Hubei Province from 2013 to 2015. Methods: From January 1, 2013 to December 31, 2015, all newly diagnosed malignant tumors were collected from cancer registration areas in Hubei Province, and patients were followed up using a combination of active and passive methods. Cancer survival was analyzed using the strs package in Stata software. Observed and expected survival were calculated using the life table and Ederer Ⅱ methods, and the difference in survival rate of patients with different sex, age, urban and rural areas and different cancer species was compared. Results: From 2013 to 2015, 83 987 new malignant tumors were diagnosed in cancer registration areas in Hubei Province, including 45 742 males (54.46%) and 38245 females (45.54%). The overall 5-year relative survival rate was 41.46%, 34.43% for men and 49.63% for women. With the increase of age, the observed survival rate and relative survival rate of patients of different genders showed a decreasing trend. The 5-year relative survival rate of patients with malignant tumors was 47.58% in urban areas and 26.58% in rural areas. The observed survival rate and relative survival rate in rural areas were significantly lower than those in urban areas. The overall 5-year relative survival rates for common malignancies were 20.61% for lung cancer, 15.36% for liver cancer, 22.89% for esophageal cancer, 34.92% for gastric cancer, and 54.87% for colorectal cancer. In addition, the 5-year relative survival rates of common malignant tumors in women were 78.65% for breast cancer and 52.55% for cervical cancer. Conclusions: In Hubei Province, the survival rate of malignant tumors is different among different genders, regions, age groups and cancer species. Prevention and treatment and health education should be strengthened for malignant tumor patients in rural areas and those with high incidence and low survival rate such as liver cancer and lung cancer, and relevant strategies should be formulated according to the gender and age distribution characteristics of different cancer species.
