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 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.

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 To investigate the effect of electroacupuncture on acupoint local extracellular ionized atom concentrations under physiological status and provide a basis for exploring the mechanism of action of electroacupuncture. Method Twenty male SD rats were selected. Rat point Zusanli (ST36) was given electroacupuncture (1 mA, 0.2 ms and 2 Hz) for 60 min. Meanwhile, local tissue fluid was collected at point Zusanli and non-acupoints using a microdialyzer. The collection by molecular probe membrane sampling lasted 4 hrs: 60 min physiological status before electroacupuncture, 60 min electroacupuncture, 60 min after electroacupuncture and 120 min after electroacupuncture. Real-time analysis of the sample was made by electrolyte analysis to observe local changes in concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- at point Zusanli. Result Local Ca﹢﹢concentrations at point Zusanli increased significantly during electroacupuncture (P=0.003, vs before electroacupuncture), rose gradually afterwards and reached the peak at 60 min after electroacupuncture (P=0.75, vs during electroacupuncture). Ca﹢﹢concentrations decreased at 120 min after electroacupuncture; there was a statistically significant difference comparedwith during electroacupuncture (P=0.04). Acupoint local extracellular concentrations of Na ﹢ and Cl- also increased significantly during electroacupuncture (P<0.001, P=0.007, vs before electroacupuncture) but decreased gradually during 60 min after electroacupuncture and to (71.81±15.09) mmol/L and (57.42±14.30) mmol/L, respectively, at 60 min after electroacupuncture (P=0.09, P=0.07 vs during electroacupuncture). Acupoint extracellular K ﹢concentrations had a tendency similar to those of Na﹢and Cl- but there was no statistically significant difference. Non-point electroacupuncture slightly increased extracellular concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- but there were no statistically significant differences compared with before electroacupuncture (P>0.05). Conclusion Rat point Zusanli electroacupuncture can induce significant increases in acupoint local extracellular concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- . Ionized atom concentrations decrease in different degrees after electroacupuncture. These provide an experimental basis for studying the physiological mechanism of electroacupuncture treatment.

Objective To establish a mouse model of H.pylori infection, and to evaluate the chronic pathological changes in the gastric mucosa associated with H.pylori infection.Methods 34 male 5~6-week old SPF C57BL/6 mice were used in this study.The mice were intragastrically administrated with a suspension of H.pylori SS1 strain.Two weeks after infection, rapid urease test and PCR were performed to confirm the H.pylori infection.Successfully infected mice were randomly divided into 3 groups including the control group, 6-week and 12-week infected groups.Samples of gastric mucosa were taken for pathological analysis using HE and borax methylene blue staining.The contents of myeloperoxidase (MPO), superoxide dismutase (SOD), malondialdehyde (MDA) and catalase (CAT) in the gastric tissues were detected by biochemistry, and the expression levels of COX-2, iNOS, TNF-α and IL-1β were examined by RT-qPCR.Results Compared with the control group, H.pylori colonization was observed in the gastric mucosa of the 6-week and 12-week infected mice, with chronic inflammatory cell infiltration, glandular atrophy and intestinal metaplasia to varying extents.The contents of CAT and SOD were significantly decreased, while the levels of MPO and malonaldehyde MDA, and the expression levels of COX-2,iNOS,TNF-α and IL-1β were significantly increased (P<0.05 or P<0.01).Conclusions Intragastric administration with H.pylori in C57BL/6 mice can be successfully used to generate the bacterial colonization, leading to chronic inflammatory cell infiltration, enhanced oxidative stress, and up-regulated expression of proinflammatory genes in the gastric glandular tissues at 6 and 12 weeks after inoculation.However, the inflammatory changes are more extensive in the mice at 12 weeks after infection, with glandular atrophy and intestinal metaplasia.

Objective　To evaluate the therapeutic effect of rapid angulation rotation traction for lumbar intervertebral disc protrusion. Methods　A total of 88 patients (66 male and 22 female;age: 18-65), with a history of 2 days to 10 years were analyzed. Among them 20 cases were central protrusion 68 cases were lateral protrusion. Traction range: 60-65 mm, angle: 20°-25°, rotation degree: 20°-25°, traction time: 3 s-1 min. The process of treatment was computer designed. The traction was then 1 to 3 times, with a interval of 4-7 days between two treatments. Results　The effective rate was 96% for the case with history <1 month 96% and 85% for cases with history >1 month (P<0.01). The effective rate was 62% for central protrusion, and 87% for lateral protrusion respectively. χ2 test showed the difference was not significant. Conclusion　The rapid angulation rotation is an effective treatment for lumbar inter-vertebral disc protrusion and this non operative method should be used as early as possible.

Objective To study the diagnostic value of common inflammatory markers in patients with infectious diseases. Methods One hundred sepsis patients, 100 viral infection patients,100 pulmonary tuberculosis patients and 100 gonorrhea patients were analyzed retrospectively. The contents of procalcitonin (PCT), C-reactive protein (CRP), haptoglobin (HP), ceruloplasmin (CER), α1-acid glycoprotein (α1-AAG), α1-antitrypsin (α1-AAT), white blood cell count (WBC) and erythrocyte sedimetation rate (ESR) were measured. The receiver operating characteristic curve (ROC curve), sensitivity, specificity, positive predictive value, negative predictive value, Youden's index,positive and negative likelihood ratios and total coincidence rate were calculated respectively. Results The area under the ROC curve, sensitivity, specificity, Youden's index and positive likelihood ratios,positive predictive value and total coincidence rate of PCT in sepsis patients were 0. 895, 0.84, 0.92,0.76, 10.50, 0.91 and 0.88, respectively, which were superior to CRP, HP, CER, α1-AAG, α1-AAT, WBC and ESR. Conclusions PCT is a better inflammatory reactive parameter than other parameters currently applied in practice and may serve as a rapid and sensitive test in the early stage of severe bacterial infections.
