Objective To investigate the levels of IL-33 in the lung induced by Aspergillus fumigatus (A.fumigatus) exposure in bronchial asthmatic rats and the effects of dexamethasone.Methods Twenty-four Wistar rats were randomly and equally divided into group A (normal control),group B (asthma group),group C (A.fumigatus-exposed group),and group D (dexamethasone-treated group).B,C and D group were sensitized and challenged with ovalbumin (OVA) to establish asthmatic models.Then,group C and D were given A.fumigatus spores intranasally.Group D was pre-treated with dexamethasone during ovalbumin challenge.Group A was sensitized and challenged intranasally with normal saline as control.Airway hyperresponsiveness,eosinophils percentage and serum IgE levels were measured to confirm the establishment of asthmatic model.Expression of IL-33 in the lung were quantified by ELISA and qRT-PCR.Lung tissues and blood were plated on the potato dextrose agar (PDA) medium and cultivated for 24 h to measure the number of colony.Results Eosinophils percentage in bronchoalveolar lavage fluid (BALF),IgE levels in serum and IL-33 levels in the lung in group B and C were much more higher than in group A (P＜0.05),and the increasing range in group C was more obvious than group B.However,the changes of sRaw values in these groups had no statistical significance.Esosinophils percentage in BALF and IL-33 levels in the lung were significantly decreased (P＜0.05),and IgE levels in serum was slightly decreased (P＞0.05) in group D when compared with group C,but the ratio of A.fumigatus colonization in the lung was higher than group C.Conclusions Dexamethasone can inhibit the expression of IL-33 in the lung induced by A.fumigatus exposure in an asthmatic rat,but it also increases the risk of fungal colonization in the airway.Anti-IL-33 antibody treatment needs further research.

Objective To explore the effect of the contrast frame mirror and the corneal contact lens correction on the optical properties of the human eye.Methods120 cases of myopia patients from 2014 September to September 2015 in our hospital for vision correction were randomly divided into two groups: control group, observation group wearing frame mirror, wearing contact lens, the optical properties of the eye were compared between the two groups.ResultsThe corrected visual acuity of observation group hadno significant difference compared with the control group;no significant difference in the values of refractive foveal contrast;foveal refractive value contrast in the two groups had no statistical difference;the observation group T30 degrees for peripheral refraction was (1.00±0.21) D, N30°peripheralrefraction was (0.34±0.08) D,were significantly lower than the control group (P<0.05).The good rate of observation group was significantly higher than the control group, the incidence of corneal complications was significantly lower than that of the control group (P<0.05).ConclusionThe frame and the corneal contact lens can be well corrected visual acuity, the corneal contact lens for the correction of certain peripheral hyperopic defocus has advantages, can effectively reduce the peripheral hyperopic defocus, delaying myopia, and improve the comfort and safety.

Objective To study the regulatory effect of paclitaxel injection on vascular endothelial related factors in serum of uterine cancer patients.Methods 30 cases of uterine cancer patients treated with paclitaxel (observation group)and 30 cases of uterine cancer patients treated with surgery (control group)were selected.Chemiluminescence immunoassay (CLIA)was used to detect expressions of serum tumor necrosis factor(TNF), Interleukin-8(IL-8)and tumor specific growth factor (TSGF).Results Before treatment,there was no significant difference between the serum TNF, IL-8 and TSGF in observation group and control group(P<0.05).At 3 months after treatment,the serum TNF,IL-8 and TSGFwere significantly lower than before treatment ,which was statistically significant(P<0.05).Conclusion Paclitaxel can decrease serum TNF,IL-8 and TSGF in patients with uterine cancer,which provides a new theoretical basis for its anticancer effects.

Objective To observe the effects of bone marrow mesenchymal stem cells(BMMSCs) conditioned-medium (B-CM) on apoptosis in cultured cortical neurons after hypoxia-reoxygenation in vitro in rats.Methods BMMSCs were isolated,cultured and expanded,the culture me-dium was substituted by new medium that contain no serum when cells grew to 90% confluence.After cultured for 24 hours,the medium was collected as B-CM.Cortical neurons of mouse cultured for 8 days were divided into three groups:normal control groups,hypoxic group,B-CM disposed groups.Cell viability were detected by 3-(4,5-dimethlthiazd-2-yl)-2,5-diphenyltetra-zoliu bromidel (MTT) methods and the apoptosis of neurons was examined by flow cytometry and telemicroscopy on hypoxia for 0,6 hours and hypoxia-reoxygenation for 24 hours,respectively.Results Compared with control group,hypoxia for 6 hours could decrease cell viability,hypoxia-reoxygenation for 24 hours increased the cell apoptosis ratio remarkably(P

Total RNA from JM cell lines secreting T leukmia derived suppressor factor was isolated using single—step method of acid guanidium followed by oligo—d(T)—cellulose affinity chromotogra-phy for purification of mRNA.TLSF_(JM)mRNA was mieroinjected into Xenopus Laevis Oocytes.The inhibitory activity in Xenopus Laevis Oocytes culture supernatant or lysate was detected by PHA plus IL—2 induced—mouse thymocyte proliferation assay The results showed that Xeno-pus Laevis Oocytes could efficiently translate exogenous mRNA,the trans ated products mainly existed inside oocytes and approximately2% of the products was secreted into the culture super-natant.Success in TLSF_(JM)mRNA translation in vitro might provide the basis for establishment of cDNA library and TLSF_(JM)gene cloning and expression.

Clinical practice is an important transformational process for medical students to grow into qualified doctors.Interest conflict exists between patients and medical students during clinical practice,which is sketched and analyzed in this paper.It is held that it is of crucial significance to strengthen the education of medical ethics for physicians and medical students during clinical practice.

Objective To evaluate the clinical application of transrecral ultrasound in the treatment of prostate cancer.Methods 23 cases of prostate cancer treated with PSA,CT,MRI and postoperative pathological confirmation were analysed respectively and the results of transrectal ultrasound were compared.Results The diag- nostic match rate of transrectal ultrasound for prostate cancer was 77%.Transrectal ultrasound showed hypoecho nodes in prostate.Conclusion Transrecral ultrasound could detect prostate cancer.
