OBJECTIVE: To investigate the effect of aerobic exercise on immune factor IL-4, TNF-alpha in patients with allergic rhinitis, which provide a theoretical basis for the treatment of allergic rhinitis. METHOD: Thirty-two allergic rhinitis patients were selected and divided into a control group (14 people) and the experimental group (18 people). During the treatment, both groups receive conventional symptomatic treatment. Meanwhile, aerobic exercise therapy is applied to the experimental group for 40 - 60 minutes a day, 3 - 4 days a week. Serum IL-4, TNF-alpha and allergic rhinitis symptoms graded scoring were tested before and after 6 month therapy. RESULT: After six months of exercise intervention, the 11-4, and TNF-alpha levels of experimental group were significantly lower than the level of control group. The symptoms score is also significantly decreased in experimental group. CONCLUSION Aerobic exercise had good therapeutic effect in patients with allergic rhinitis. The mechanism may be that aerobic exercise can reduce the level of IL-4 and TNF-alpha, which can relieve infiltration and activation of inflammatory cells.

Objective To analyze the coverage of iodized salt and the focus population iodine nutrition after implementing new standard of iodized salt in Hainan Province.Methods Eighteen cities (counties,districts) were divided into eastern coastal,western coastal and inland areas according to coastline and terrain of Hainan Province in 2013.One township (town,street) was sampled from each city (county,district) in the east,the west,the south,the north and the center of these areas.Four villages (committees) and 15 households in each village (committee),and 40 children aged 8-10 in one primary school,20 pregnant women and lactating women were sampled from each township (town,street).Iodized salt samples collected from household were monitored by the method of direct titration;random urine samples of children aged 8-10,pregnant woman and lactating woman were tested by arsenic cerium catalytic spectrophotometry.Results Totally 6 310 edible salt samples were tested,and the median of salt iodine was 25.9 mg/kg.The coverage of iodized salt was 97.92％ (6 179/6 310).Residents consumption rate of qualified iodized salt reached 95.47％ (6 024/6 310),and the rate of non-iodized salt was 2.08％ (131/6 310).About 4 444 urine samples of children aged 8-10 were examined,and the median of urinary iodine was 165.4 μg/L,in which suitable urinary iodine (100-199 μg/L) accounted 49.3％ (2 194/4 444);about 1 286 urine samples of lactating woman were examined,the median of urinary iodine was 122.3 μg/L,≥ 100 μg/L was 60.6％ (779/1 286);about 813 urine samples of pregnant woman were examined,the median of urinary iodine was 126.6 μg/L,59.6％ (485/ 813) of this group were urinary iodine deficiency (＜ 150 μg/L).There were significant differences between the three groups in the east,the middle and the west areas of Hainan Province (children:176.7,147.7,158.0 μg/L,lactating women:148.7,108.7,106.7 μg/L,pregnant women:146.7,108.0,147.1 μg/L,H =34.70,26.76,35.95,all P ＜ 0.01).Conclusion The results have showed that pregnant woman are iodine deficiency,they should be given more iodine.

Objective To investigate the clinical significance of high mobility group box-1 protein (HMGB1) in chronic,severe hepatitis B patients and liver cirrhosis.Methods The contents of HMGB1 was measured by enzyme-linked immunoassay (ELISA) in the patients (include 40 patients with chronic hepatitis B and 18 severe hepatitis B patients and 18 liver cirrhosis patients) and 20 health controls.The levels of relative biochemical indicators,prothrombin time activity percentage (PTA) and the hepatic fibrosis were determined by biochemical methods.Results The contents of HMGB1 was significantly increased in severe hepatitis patients in comparison with that in chronic hepatitis B patients(P ＜0.01).The contents of HMGB1 in the chronic hepatitis were significantly increased in health controls(P ＜0.01).The contents of HMGB1 had significant difference among the liver cirrhosis patients,the severe hepatitis patients and the chronic hepatitis(P ＜0.01).There was positive correlation among the contents of HMGB1 and total bilirubin (TBIL),the proportionality of aspartate aminotransferase and alanine aminotransferase (AST/ALT),hyaluronic acid (HA) and procollagen Ⅲ N-terminal peptide (P Ⅲ NP) (r = 0.865,0.646,0.783,0.662,P ＜ 0.01).There was negative correlation among the contents of HMGB1 and prothrombin time activity percentage (PTA) and albumin (ALB) (r =-0.915,-0.852,P ＜0.01).Conclusion The contents of serum HMGB1 were closely associated with disease severity in chronic hepatitis B patients.HMGB1 was an index to auxiliary diagnosis hepatic fibrosis.

OBJECTIVE To investigate the drug susceptibility of clinical isolates in local region for using antibiotic reasonably. METHODS Totally 3 170 strains of clinical isolates were identified by API and Microscan and tested for drug resistance against antimicrobial agents by K-B method. WHONET5.4 was applied for analysis. RESULTS The commonly encountered bacteria were Pseudomonas aeruginosa (24.3%), Acinetobacter baumannii (10.9%), Klebsiella pneumoniae (10.4%), Escherichia coli (8.9%), and Staphylococcus aureus (SA,8.0%). In Gram-negative isolates, the resistance rate to meropenem was 19.7%, and to piperacillin-tazobactam was 26.5%. The incidences of E.coli and K. pneumoniae isolates producing extended spectrum beta-lactamases (ESBLs) were 49.1% and 33.5%, respectively. In Gram-positive isolates, the susceptibility rate to vancomycin and teicoplanin both was 100.0%. The oxacillin resistant rates of SA and coagulase negative Staphylococcus (CNS) were 54.2.0% and 82.3%. CONCLUSIONS The production ratio of ESBLs and oxacillin resistance of bacteria in local region are high. It is important to promote the rational use of antimicrobial agents and take effective contaminant methods to reduce resistant rates of bacteria and dissemination of multi-resistant bacteria.

Objective Curculiginis extract has good scavenging effects on oxygen free radicals, and there is no curculiginis extract for AD research at home.The aim of this study was to explore the influence of Curculigoside on the cognitive learning and memory functions of senile dementia model rats induced by D-galactose combined with β-protein amyloid β25-35 (Aa25 35) and the expression level of hippocampus B-cell lymphoma-2 (Bcl-2), Bax, estrogen receptor (ER) protein and mRNA.Methods Forty SD rats weredivided into the control group (equal saline was intraperitoneal injected for six weeks consecutively, and equal saline was injected to the bilateral hippocampus in the seventh week), the model group (galactose was intraperitoneal injected for six weeks consecutively, and 4 mmol/L Aβ25-35 was injected to the bilateral hippocampus in the seventh week), the low dosage group and the high dosage group randomly (the stomach irrigation of low dosage 24mg/kg or the high dosage 72mg/kg curculigoside was applied every day, for 8 weeks), 10 rats in each group.After the treatment , the Morris water maze was conducted to test the space learning and memory functions of rats;the flow cytometry method was conducted to analyze the neuronal apoptosis conditions;the western blot was conducted to detect Bcl-2, Bax and ER protein level;the Realtime PCR was conducted to detect Bcl-2, Bax and ER mRNA level.Results Morris water maze test results: Compared with the model group, the escape latency (EL) of the rats of the model group, the low dosage group and the high dosage group on the 2nd, the 3rd, the 4th and the 5th day significantly extends (P<0.01), and the high dosage group significantly shortens (P<0.05) than the low dosage group.Space exploration test results: Compared with the proportion of the distance swum within the quadrant by the rats in the model group in the total distance [(30.14±5.10)%], that of the low dosage group, the high dosage group and the control group [(41.98±4.78)%, (46.17± 9.31)% and (50.13±6.81)%] significantly increases (P<0.01);in addition, the high dosage group is higher than the low dosage group (P<0.05).Compared with the apoptosis rate of rates in the model group[(7.11±1.78)%], that of the high dosage group, the low dosage group and the control group[(5.53±1.45)%], (4.11±1.03)% and (3.08±1.33)% significantly decreases (P<0.05).Compared with the control group, the Bcl-2 and Bax protein expression of the model group significantly increases, and the cell Bcl-1 and Bax of cells significantly decreases (P<0.05).Compared with the model group, the Bcl-2 and ER protein expression as well as the Bcl-2/Bax of the high dosage group and the low dosage group significantly increase, and the Bax protein expression significantly decreases (P<0.05).Compared with the mRNA expression (1.00 and 1.00) of Bcl-2 and ER in the control group, the mRNA expression (1.31 and 1.98) of the Bcl-2 and Bax in the model group significantly increases (P<0.05);compared with the mRNA expression (1.13 and 1.08) of Bcl-2 and ER in the model group, the Bcl-2 (1.95 and 2.01) and mRNA expression (1.81 and 1.96) of ER of the high dosage group and the low dosage group significantly increase (P<0.01).Conclusion Curculigoside plays an improving role in space learning and memory functions of senile dementia model rats, with the mechanism may be related to the protection to the hippocampus neurons by restraining Bax expression and neuronal apoptosis through the up-regulation of hippocampus ER and Bcl-2 expressions.

In order to develop a combined live vaccine that will be used to prevent against porcine parvovirus (PPV) and Pseudorabies virus (PRV) infection, the VP2 gene of PPV was inserted into the transfer vector plasmid pG to produce the recombinant plasmid pGVP2. The plasmid pGVP2 and the genome of PRV HB98 attenuated vaccine were transfected by using lipofectamine into swine testis cells for the homologous recombination. The recombinant virus rPRV-VP2 was purified by selection of green fluorescence plaques for five cycles. 6-week-old female Kunming mice were immunized intramuscularly with attenuated PRV parent HB98 strain, commercial inactivated vaccine against PPV, recombinant virus, DMEM culture solution. The injections were repeated with an equivalent dose after 2 weeks in all of the groups, and then challenged with the virulent PRV NY strain at 7 weeks after the first immunization. The recombinant virus rPRV-VP2 was successfully generated, and the recombinant virus could effectively elicite anti-PPV and PRV antibody and significant cellular immune response as indicated by anti-PPV ELISA and HI, PRV-neutralizing assay and flow cytometry. The challenge assay indicated that recombinant virus could protect the mice against the virulent PRV challenge. These results demonstrated that the recombinant virus can be a candidate recombinant vaccine strain for the prevention of PRV and PPV.
