Objective To explore the correlation of rhinovirus infection and the morbidity of asthma in children.Methods The RV gene in nasopharyngeal secretion of 30 children with asthma acute exacerbation(asthma group),30 children in asthma clinical remission(remission group) and 30 healthy children (control group) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The total serum IgE(T-IgE) was determined by chemiluminescence.The eosinophil(EOS) count (EOS%) of peripheral blood and lung function were also measured.Results The rhinovirus infection rate was 36.67% in asthma group and 3.33% in remission group.No rhinovirus was detected in control group.The rate of rhinovirus infections in asthma group was significantly highter than that in remission group and control group(?2=7.50,13.47 Pa0.05). FEV1% was (62.73?13.54)% in asthma rhinovirus infection and (86.42?17.78)% masthma with no rhinovirus infection.There was remarkable difference between 2 groups(F=14.553 P﹤0.05). The T-IgE was (836.32?44.801) kU/L and EOS% was 10.63?4.09 in asthma group with rhinovirus infection.The total IgE was (439.10?231.28) kU/L and EOS% was 5.04?2.64 in asthma group with no rhinovirus infection.There was significant difference between 2 groups(U=2.475,F=20.806 Pa0.05).Conclusions There is a close correlation between rhinovirus infection and acute attack of asthma(or worsening asthma) in children. Asthma exacerbations would be likely to happened easier because of rhinovirus infection in asthmatic children with high T-IgE.

Objective To evaluate the methods and efficacy of microsurgical treatment for the premalignant and malignant lesions of the conjunctiva. Methods Forty-seven patients witn premalignant and malignant lesions of the conjuncitva were managed by microsurgical, these patients include 12 melanoma, 26 squamous cell carcinoma, 6 Bowen’ diseases, 3 primary acquired melanosis. The surgical method differs with limbal tumors, extralimbal tumors, and primary acquired melanosis. Results In all 47 patients, the tumor was completely removed in in one procedure. After follow-up for 4~60 months(mean 17 months), these were no tumor recurrence. Conclusion It is effective methods that premalignant and malignant lesions of the conjunctiva are managed by microsurgical resection, alcohol application, and supplemental cryotherapy. Careful propeirativa clinical evaluation of patient with a conjunctiva neoplasm is important in making the correct diagnosis and planning the surgical approach.

Objective To observe the clinical efficacy of acupuncture-moxibustion plusMEI Te-lan’s manipulations in treating lumbar intervertebral disc herniation (LIDH) due to blood stagnation.Method Totally 248 LIDH patients due to blood stagnation were randomized into a treatment group of 123 cases and a control group of 125 cases. The treatment group was intervened by acupuncture-moxibustion plusMEI Te-lan’s manipulations, while the control group was by acupuncture-moxibustion plus tuina at lower back. The short-form McGill Pain Questionnaire (SF-MPQ) and Oswestry disability index (ODI) were observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The total effective rate and recovery-markedly effective rate were respectively 80.5% and 52.0% in the treatment group, versus 72.8% and 20.0% in the control group. There was a significant difference in comparing the recovery-markedly effective rate between the two groups (P<0.05). In the treatment group, the Pain Rating Index (PRI) score, Visual Analogue Scale (VAS) score, Present Pain Intensity (PPI) score, and ODI score were significantly changed after 3-day, 6-day, and 20-day treatment compared to the scores before treatment (P<0.05). After 20-day treatment, the PRI, VAS, PPI, and ODI scores of the treatment group were significantly different from that of the control group (P<0.05).Conclusion Acupuncture-moxibustion plusMEI Te-lan’s manipulations is an effective method in treating LIDH due to blood stagnation.

We discussed the influence of liquid nitrogen cryopreservation to survive capability of Babesia microti standard strain.The whole blood of mice infected with Babesia microti was put in liquid nitrogen to cryopreservation for 1 month,3 months,6 months,9 months,the whole blood was get out respectively and recovery at room temperature,and infected 3 mice respectively,100 μL/ mouse (the first generation after redissolution,the experiment group).In the same time,3 mice were also infected with Babesia microti as the animal conservation control group.When the infection rate was at a high level,the whole blood of the experiment group mice were injected into 3 normal BALB/c mice (the second generation after redissolution),to observe the changes of the Babesia microti form and proliferation situation,and also to observe the infection rate of the first and the second generation after redissolution in different conserving time.Compared with Babesia microti of animal subcultivation,the form of Babesia microti of liquid nitrogen cryopreservation changed a little.Small trophozoites,annular trophozoites,schizont and immature and mature merozoite and other form can also be seen.Compared with Babesia microti of animal subcultivation,the first time to see the worms and the time attaining to the high infection level were 1 to 2 days later,but for the second generation after redissolution,it is the same.There was no significant difference in different conserving time of 1,3,6,9 months.The influence of liquid nitrogen cryopreservation to survive capability and worm form of Babesia microti is a little,so liquid nitrogen cryopreservation can be a better way to conserving Babesia microti.

Objective: To observe the effects of manganese( Ⅲ ) meso-tetrakis (N, N'-diethylimidazolium-2-yl) porphyrin (MnTDM) in treatment of early Parkinson's disease(PD) mouse model induced by subcutaneous injection of 1-methyl-4-phenyl1, 2, 3, 6-tetrahydropyridine(MPTP) and to discuss its possible mechanism. Methods:Forty male C57BL/6 mice were evenly randomized into 4 groups: MPTP model group(subcutaneous injection of 25 mg/kg MPTP for 3 days), MnTDM+ MPTP group (15 mg/kg MnTDM was subcutaneously injected 1 h before MPTP injection), MnTDM control group, and normal saline group. Performance of animals in the pole and swimming test was observed 3 days after the last injection. Levels of dopamine (DA) and its metabolites(3,4-dihydroxyphenylacetic acid [DOPAC] and homovanillic acid [HVA]) in the striatum of animals were measured by high-performance liquid chromatography with an electrochemical detector(HPLC-ECD). Thiobarbituric acid (TBA) method was used to examine the levels of malondialdehyde(MDA). Results: Acute injection of MPTP could be used for establishment of PD model. The striatal levels of DA, DOPAC and HVA in MPTP group were significantly lower(P＜0.01)and the striatal level of MDA was significantly higher(P＜0.05) than those of the control group. MPTP had no obvious effect on the behavioral performance of the animals in a short term. MnTDM could partly inhibit the above effects of MPTP. Compared with MPTP group, MnTDM+ MPTP group had significantly higher DA, DOPAC, and HVA levels and significantly lower MDA level(all P＜0.05). There was no significant difference in the behavioral indices of animals between the 4 groups. Conclusion:MnTDM can inhibit lipid peroxidation and promote DA production; it has preventive and therapeutic effects on MPTP induced PD.

Objective To probe the relationship between the patients′ prognosis and the gene of multidrugs and drug resistance in uveal melanoma. Methods The gene expression of cyclin D1, epithelial growth factor receptor (EGFR), non metastasis gene 23 (nm 23), P glucose protein (P gp), multidrug resistance relation protein (MRP) and lung resistance protein (LRP) expression in 96 cases of uveal melanoma were detected by depigment immunohistochemistry. The patients with complete anamnesis data were observed continuously, and the follow up results were classified. Results Among the 96 cases of uveal melanoma, the epithelioid cell type was in 21, the mixed cell type in 56, and the spindle cell type in 19; including 76 at intraocular stage and 20 at extraocular stage. As the level of metastasis suppress gene nm 23 expression decreased and the level of cyclin D1 and EGFR expression increased, the expression level of drug resistance genes increased. The levels of LRP and MRP had negative correlation to the expressions of nm 23 and postive correlation to the expressions of nm 23, Cyclin D1 and EGFR. In 58 patients′ who were observed continuously, 19 died in 5 years and 26 survived over 5 years. Conclusion There are significant association between patients′ prognosis and multidrug and drug resistance gene in uveal melanoma.

Objective To investigate the changes of A20 expression stimulated by free fatty acids (FFA) and its pathway.Methods HepG2 cells and U937 cells were stimulated by 0.5 mmol/L mixed FFA.The expression of A20,phosphor-p65 and phosphor-IκBα of neclear factor (NF)-κB pathway and phosphor-c-Jun N-terminal kinase (JNK),JNK,phosphor-extracellular signal-regulated kinase (ERK),ERK,phosphor-p38 and p38 of mitogen-activated protein kinase (MAPK) pathway were detected by Western blotting.The level of interleukin (IL)-12p,IL-1β,tumor necrosis factor (TNF)-α,IL-6,IL-10 and IL-8 cytokines in the supernatant of cell culture were detected by flow cytometry.T-test was performed for statistical analysis.Results The level of A20 changed along with the stimulated time of FFA.NF-κB and MAPK pathways were activated after FFA stimulation.The secretion of IL-6 and IL-8 increased after HepG2 cells stimulated by FFA and both reached peak at 24 hour.Compared with control group,the difference in IL-8 was statistically significant ((423.8 ± 8.9) pg/mL vs (12.4 ± 4.5) pg/mL,t=41.28,P＜0.01).The difference in IL-6 was also statistically significant ((4 082±423.6) pg/mL vs (52.9±29.5) pg/mL,t=9.49,P＜0.01).After U937 cells were stimulated by FFA,the secretion of IL-8 increased compared with control group.And in a certain period of time the secretion was time dependence.The maximum secretion of 24 hours was (200.6±5.7) pg/mL vs (5.0±3.9) pg/mL,and the difference was statistically significant (t=28.16,P＜0.01).IL-10,IL-12p,IL-1β and TNF-α were detected.Both NF-κB pathway and MAPK pathway were detected.Conclusions The in vitro FFA mediated steatotic cell model could induce the expression change of A20 and secretion of inflammatory cytokines.NF-κB and MAPK pathways involved in the response to FFA in HepG2 cells and U937 cells.
