Objective To discuss the clinical effect of pulmicort respules inhalation in children with acute infectious laryngitis.Methods We selected acute infectious laryngitis in our hospital from November 2015 to November 2016,106 children were divided into two groups,the control group and the observation group of 53 cases,of which the control group of children with conventional treatment,the observation group to take Pulmicort respules inhalation treatment,the two comparison(P<0.05).The total effective rate of the observation group and the control group were 100％and 90.56％respectively(P<0.05).Results The treatment effect of the observation group and the control group were observed and compared(P<0.05),and the improvement of the observation group after treatment and the time of symptom extinction were significantly better than that of the control group(P<0.05); The clinical symptoms of both groups before and after treatment were improved(P<0.05).Conclusion The treatment of children with acute infectious laryngitis by atomizing inhalation of pulmicort respules can obtain obvious therapeutic effect and reduce the adverse reaction caused by improper use of drugs,(fever,cough,wheezing,etc.)have a good improvement in clinical application worthy of recognition.

ObjectiveTo analyze the CT appearances of primary pulmonary non-Hodgkin lymphoma(PPNHL)in order to improve its diagnosis.MethodsCT manifestations of 19 cases with PPNHL confirmed by pathology and clinical follow-up were retrospectively analyzed.ResuitsNodules 7 cases and masses 8 cases in PPNHL were ill-defined and markedly enhanced,in which air bronchogram was commonly seen.Muhiple patchy areas distributed in the bilateral lungs were found in 9 cases.Consolidation 7 cases was lobar and markedly enhanced,in which air bronchogram was commonly seen.Interstitial change manifested as bilateral diffuse ground-glass opacities and reticular shadow was found in 1 case.Mixed imaging manifestations were detected in 10 cases.Pleural effusion 4 cases was uncommon.Conclusion CT manifestations of PPNHL are varied,but some specific imaging features still exist,CT examination combined with clinical manifestations is helpful for the diagnosis of PPNHL.

As a member of nuclear receptor superfamily, farnesoid X receptor (FXR) has been shown to regulate numerous metabolic pathways, which include playing an important role in bile acid metabolism, maintaining lipid and glucose homeostasis when FXR is activated. With the prevalence of the glucose and lipids disorder, FXR attracts increasing attention. It may be a potential target for the treatment of type 2 diabetes mellitus and lipid disorders.

To observe the clinical outcome of implanting AcrySof lQ Toric intraocular lens to correct corneal astigmatism in cataract surgery, and to evaluate the result and rotational stability of AcrySof lQ Toric after cataract surgery.
●METHODS: A retrospective study of 26 eyes in 21 cataract patients with corneal astigmatism. All patients implanted AcrySof lQ Toric intraocular lens. The preoperative and postoperative uncorrected visual acuity ( UCVA ), best corrected visual acuity ( BCVA ), preoperative corneal astigmatism, anticipated residual astigmatism, total astigmatism, postoperative residual astigmatism and Toric lens axis were detected and measured.
●RESULTS: All patients' visual acuity and best corrected visual acuity improved significantly. The mean refractive cylinder decreased significantly after surgery from (2. 05± 0. 57)D to (0. 55±0. 33)D (t = 13. 574, P<0. 05). There was no significant difference between preoperative ( 0. 47 ± 0. 19)D and postoperative corneal astigmatism (t = 1. 149, P > 0. 05 ). Three months after surgery, there was no significant difference between preoperative (2. 01±0. 58)D and postoperative (-1. 89±0. 53) D corneal astigmatism (t =1. 908, P> 0. 05). The rotation of intraocular lens were <20°, the mean rotation was 3. 65°±2. 86°.
●CONCLUSlON: The AcrySof lQ Toric lens make cataract patients enjoy the better UCVA including good rotational stability in the correct of corneal astigmatism. The AcrySof lQ Toric implantation is an effective option for the correct of preexisting corneal astigmatism in cataract surgery.

Gene chip is a research tool on molecular biology which can detect generous gene expression rapidly.The studies on gene chip of leiomyoma have revealed the changes of gene expression related to cell growth,proliferation,apoptosis,metabolism,angiogenesis,formation of extracellular matrix,cell differentiation and immunity.The article reviews the advance on gene chip of leiomyoma and approaches the pathogenesis of leiomyoma on molecular level.

Objective: To establish a method for the determination of atractylenolide Ⅰ in Atractylodes macrocephala by HPCE. Methods:The separation conditions of HPCE were as follows:50 mmol·L-1 borate buffer was used as the running buffer, the UV de-tection was set at 210 nm, the separation voltage was 20 kV, the column temperature was 25℃ and the pressure injection was 50 mbar × 5 sec. Results:The lower detection limit was 0. 5 μg·ml-1 . The concentration of atractylenolide Ⅰ showed a linear plot within the range of 2-100 μg·ml-1(r=0. 996 0). The average recovery was 97. 1%, and the intra-and inter-day RSD was 1. 3% and 2. 5%, respectively. Conclusion:The established method is simple, sensitive and economic. The method is suitable for the quality control of atractylodes macrocephala.

Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.

BACKGROUND:Alendronate is a new generation of diphosphate,which is the second generation of osteoporosis drugs.It is widely used to treat diseases related to increase of bone absorption in clinic.OBJECTIVE:To observe the effect of alendronate on the proliferation and the mRNA expression of osteoprotegerin(OPG) and receptor activator of nuclear factor kappa B ligand(RANKL) of human osteoblasts.DESIGN,TIME AND SETTING:A single sample observational experiment was performed at the Basic Research Institute of Chongqing Medical University from November 2007 to March 2008.MATERIALS:Osteoblasts were isolated from cancellous bone in a surgical operation.Alendronate was the product of Merck Sharp & Dohme S.p.A.METHODS:Osteoblasts were cultured with various concentrations of alendronate(1?10-9,1?10-8,1?10-7,1?10-6,1?10-5,1?10-4 mol/L).Osteoblasts cultured without alendronate were assigned as controls.MAIN OUTC0ME MEASURES:①The morphology and growth of osteoblasts were observed.②Effect of alendronate on the proliferation of osteoblasts were detected by MMT method.③The effect of various concentrations of alendronate on the mRNA expression of OPG and RANKL were detected by using RT-PCR.RESULTS:1?10-5 and 1?10-4 mol/L alendronate inhibited the proliferation of osteoblasts.1?10-9-1?10-6 mol/L alendronate promoted the proliferation of osteoblasts,and the 1?10-8 mol/L alendronate had the strongest effect.Alendronate inhibited RANKL mRNA expression in a concentration-dependent manner,1?10-5 mol/L alendronate had a strongest effect at 72 hours after culture(P
