Objective To find out the relationship between kidney- yang- deficiency syndrome and the Th1/Th2 expression, and to investigate the effect of kidney- yang warming therap yon the Th1/Th2 expression. Methods Kidney- yang- deficiency rat models were firstly induced by adenine and then were sensitizated by inhalation of ovalbumin to establish allergic rhinitis (AR)models .The treatment group was given Jinkui Shenqi pill. After treatment , the changes of behavior , secretion of nasal cavity and nasal mucosa were observed. The levels of Th1 cytokines IFN- ? , IL- 2 and Th2 cytokines IL- 4 , IL- 5 in serum were determined by ELISA. Results The behavioral score in AR group and kidney- yang- deficiency AR group was higher than that in the treatment group and normal control group ( P

Objective To identify the high-touched object surface in different special intensive care units(ICUs) through the observation and statistical analysis on the number of touching with common object surfaces in different ICUs, so as to provide basis for hospital environmental management.Methods Direct observation method was used to observe the daily activities of health care workers, the number of touching with various common object surfaces was recorded, Poisson distribution was adopted to statistically analyze the data.Results The average number of touching from high to low was as follows : medical record folder(n=28.00), chair(n=18.38), emergency rescue cart(treatment cart, n=17.29), bed surface(n=13.90), intravenous infusion line(n=13.76), medical pen(n=13.38), and intravenous transfusion pump(n=11.81), these objects accounted for 64.01% of all surface touching number.Different special ICUs were slightly different, general ICU high-touch object included the first 6 categories;cardiothoracic surgery ICU included the above 7 categories besides keyboard and mouse;internal medicine ICU included the first 6 categories and mobile phone.Conclusion High-touched object surface varied with different special ICUs of the same hospital, hospital should make the corresponding disinfection management measures according to the actual situation of high-touched surface of each department, so as to reduce the incidence of healthcare-associated infection.

Objective To determine the expression profile of serum microRNAs(miRNAs) in early-onset familial Alzheimer's disease (EO-FAD) patients. methods miRNA microarrays were performed to detect the expression profile of serum miRNAs in 2 cases of EO-FAD patients,2 cases of EO-FAD carriers and 2 cases of normal controls.Preliminary bioinformatic analysis was conducted. Result sIt was found that 21 miRNAs were up-regulated and 22 miRNAs were down-regulated in serum of EO-FAD patients,the differences were statistically significant(P<0.05).miR-5704(P=0.0002),miR-4639-3p(P=0.0195),miR-107(P=0.0204) were markedly up-regulated,miR-5572(P=0.0008),miR-204-3p(P=0.0014),miR-542-5p(P=0.0106) and miR-155-5p(P=0.0240) were markedly down-regulated.Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis suggested that the dysregulated miRNAs may be involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.Conclusion miR-5704,miR-4639-3p,miR-107,miR-5572,miR-204-3p,miR-542-5p and miR-155-5p may be used as potential biomarkers of EO-FAD,and involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.

Background: CKLF-like MARVEL transmembrane domain containing (CMTM) superfamily is involved in the occurrence and development of inflammation, cancer and a variety of diseases.Human CMTM3 has been proposed as a putative tumor suppressor gene.Aims: To investigate the expression of CMTM3 in Helicobacter pylori (Hp) infection-related chronic gastritis and its significance.Methods: Sixty cases of outpatients with chronic gastritis (30 Hp-positive and 30 Hp-negative) were enrolled for detection of CMTM3 and interleukin-6 (IL-6) expressions in gastric mucosa by immunohistochemistry.The correlation of expressions of CMTM3 and IL-6 was analyzed.Results: The positivity rates of CMTM3 and IL-6 in gastric mucosa were significantly higher in Hp-positive chronic gastritis than in Hp-negative ones (CMTM3: 63.3% vs.30.0%, P<0.05;IL-6: 73.3% vs.13.3%, P<0.01).In patients with Hp-positive chronic gastritis, CMTM3 and IL-6 were co-expressed in 53.3% (16/30) of the patients and localized in the same position.Expression of CMTM3 was positively correlated with IL-6 expression in Hp-positive chronic gastritis patients (r=0.58, P<0.05).Conclusions: CMTM3 is highly expressed in chronic gastritis patients with Hp infection.It may participate in the occurrence and development of Hp infection-related chronic gastritis with inflammatory cytokines such as IL-6.Hp infection might be one of the mechanisms involved in CMTM3 up-regulation.

Objective To investigate the phenotypes and genetics of an early-onset familial Alzheimer′s disease ( EO-FAD ) family.Methods The clinical manifestations , brain MRI results and neuropathological findings of the proband and pedigree members of the EO -FAD family were evaluated. Autopsy was performed in the proband . Results Fifteen members of this family had a presenilin 1 (PSEN1) p.G378E mutation and nine of them had clinical manifestations or the MRI changes of EO -FAD. Neuropathological findings from autopsy of the proband disclosed moderate cortical atrophy throughout the brain, especially in frontal lobe and temporal lobe .Neuronal loss with gliosis was observed in the cortices of the frontal, temporal and occipital lobes , as well as in parahippocampal gyrus .Numerous senile plaques and neurofibrillary tangles were present in the cerebral cortex .The proband′s younger sister showed similar clinical presentations and MRI changes , and other members of this family demonstrated progressive memory loss.Conclusion A p.G378E mutation in the PSENl gene was identified in a Chinese EO-FAD pedigree.

Objective To study the association between the single nucleotide polymorphism (SNP) of SEPT14 (rs77231105,rs10241628,rs11981883,rs73701167) and sporadic PD in Chinese Han populationin of Southwest Shandong.Methods One hundred and eighty PD patients from Southwest Shandong served as PD patient group and 200 healthy subjects from Southwest Shandong served as control group in this study.The distribution frequencies of alleles and genotypes in SNP of rs77231105,rs10241628,rs11981883 and rs73701167 were compared by PCR and sequencing respectively.Results No significant difference was found in the distribution frequencies of alleles and genotypes in rs77231105,rs10241628,rs11981883 between the two groups (P＞0.05).The distribution frequency of rs73701167 was significantly higher in PD patient group than in control group (31.1％ vs 20.5％,OR=1.75,95％CI=1.261-2.428,P=0.001).Conclusion The SNP of SEPT14 rs77231105,rs10241628 and rs1198188 are not associated with PD,the SNP of rs73701167 is associated with PD in Chinese Han population of Southwest Shandong.The allele C is a risk factor for PD.

OBJECTIVETo study the relationship between the genetic diversity and chemical variation of Cinnamomum migao.

METHODISSR marker technique was used to research the genetic structure of 9 population, GC-MS was used to analyze the main ingredients of the volatile oil in C. migao.

RESULTThe analysis on the main ingredients of the volatile oil showed that there were significant or extremely significant differences in 9 populations. The minimum variation index of population was Yunnan Funing and the maximum variation index of population was Guangxi Yueye. ISSR marker analysis showed that the average of polymorphic loci percentage (P) was 42.41%, expected heterozygosity (H) was 0.181 0, Shannon's information index (I) was 0.293 8, the Nei's genetic diversity (H(s)) in the group was 0.188 9, genetic differentiation index (G(st)) was 2.269 1. The relationship between the genetic diversity and chemical variation showed that there was no significant correlation between the main ingredients of the volatile oil and 4 indexes of genetic structure of C. migao.

CONCLUSIONThe genetic diversity of C. migao was relatively high at the population levels, while it is low within the population levels, the relationship between chemical variation and genetic diversity was not obvious, that may indicate that other factors causes the chemical variation of C. migao.
