Objective To explore the effect of oxymatrine o n the airway inflammation and the cytokine production in asthmatic mice. Methods Forty BALB/c mice were divided into four groups in cluding a control group (group A), an asthmatic model group (group B), a dexamet hasone treatment group (group C) and a oxymatrine treatment group (group D). Ast hma mouse models in group B, group C and group D were prepared by injecting oval bumin (OVA) into the abdominal cavity and inhalation of aerosol. Group C were in jected dexamethasone, and group D recceived oxymatrine on day 15 to 22 .The numb er of EOS and the concentration of IL-4 and IL-5 and IFN-? in th e mouse bronchoalveolar lavage fluids (BALF) were detected. Results Oxymatrine could significantly reduce the mumber of EOS and the concentration of IL-4 and IL-5, and increase the level of IFN-? in the BALF of asthmatic mice. Significant difference was fo und between group D and group A or B(P0.05). Conclusion Oxymatrine can remarkably reduce the mumber of i nflammation cells in the BALF, and influence the level of cytokines so as to imp rove airway inflammation in the patients with asthma.

Objective To explore the relative factors of polycystic ovarian syndrome (PCOS) in infertile women.Methods Ninety-eight infertile women diagnosed PCOS at affiliated hospital of the Chinese People's Armed Force Logistic college from Jan.2008 to Dec.2012 were served as PCOS group.Two hundred and eighty infertile women with normal ovarian structure according to laparoscopic examination result were selected as control group.The general information,factors related infertile and laparoscopic examination of the two groups were recorded.Results Fifty-one cases (52.0％) in PCOS group were with menarche age earlier than 13 years old,higher than that of control group (113 (40.4％),x2 =4.03,P ＜ 0.05).Eleven cases (11.2％) in PCOS group were with abnormal menstruation cycle,higher than that of control group (12 (4.3％),x2 =6.12,P ＜ 0.05).The incidence of pelvic adhesions in PCOS group was lower than the control group(60(21.1％) vs.224(40.4％),x2 =13.70,P ＜0.05).Irregular menstruation cycle was risk factor of PCOS (OR=1.770,95％ CI:1.09-2.88,P =0.002).Conclusion Women with earlier menarche and irregular menstruation cycle should be paid more attention in terms of PCOS,early screening,discovery,prevention and treatment,so as to reduce the incidence of PCOS induced infertility and the long-term complications.

A Web-based technology system was put forward aiming at the actual problems of the long maintenance cycle and the difficulties of the maintenance and repairing of medical equipments. Based on analysis of platform system structure and function, using the key technologies such as search engine, BBS, knowledge base and etc, a platform for medical equipment service technician to use by online or offline was designed. The platform provides users with knowledge services and interactive services, enabling users to get a more ideal solution.

Objective To investigate relations between villus Benzo (a)pyrene (BaP)-DNA adducts and blighted ovum in early pregnancy, and to explore possible environmental factors influencing embryo development. Methods One hundred and two pregnant women with blighted ovum were selected into this study as research group; and 102 normal pregnant women were taken as control group; the age, gravidity, parity and gestational weeks of the two groups were matched. After artificial abortion, villi of the patients were collected and washed by normal saline. Then, the tissue was homogenated and genome DNA was extracted to detect quantity of the tissue. BaP-DNA adducts levels were examined by high-performance liquid chromatography-fluorescence method (HPLC). The personal information of pregnant women was collected by questionnaire. Logistic regression model was used to investigate the association between BaP-DNA adducts and blighted ovum. Results BaP-DNA adducts level in villi of research group [(8. 9±8. 2) adducts/108 nucleotides] was significantly higher than that of control group [(2. 0±1. 4) adducts/108 nucleotides], P＜0.05. The higher the BaP-DNA adducts in villi, the higher risk the blighted ovum; when the BaP-DNA adducts level increased to 6.06 adducts/108 nucleotides, the risk of blighted ovum might increase 59.39 times (95% CI:15.50-227.55). Maternal education level was a protective factor (OR=-0.21, 95%CI:-0. 19--0.03) after controlling potential confounders. Conclusions High level of villi BaP-DNA adducts might increase the risk of blighted ovum in early pregnancy, and could have an adverse effect on embryo development.

Objective To compare the accuracy of nucleic acid detection and antibody detection for diagnosing human immunode‐ficiency virus(HIV) infection .Methods Retrospectively analysed data of nucleic acid detection and antibody detection from 124 ca‐ses of patients diagnosed with HIV infection from 2005 to 2014 .The positive rates of the two methods were compared respectively in patients with early‐stage of HIV infection(76 cases) and patients with intermediate and advanced stage of HIV infection (48 ca‐ses) .Results In patients with early‐stage of HIV infectionn ,the positive rate of nucleic acid detection (94 .74% ) was higher than that of antibody detection (84 .21% );while in patients with intermediate and advanced stage of HIV infection ,the positive rate of antibody detection(97 .92% ) was higher than that of nucleic acid detection (81 .25% );both had statistically significant difference (P<0 .05) .Conclusion On the early stage of HIV infection ,the accuracy of nucleic acid detection is higher than that of antibody detection ;while on the intermediate and advanced stage of HIV infection ,antibody detection shows better accuracy .

Objective To screen for proteins interacting with novel gene AngRem104 and to identify the putative interaction of novel gene AngRem104 and Bardet-Bied1 syndrome 2 (BBS2) protein in mammalian cells. Methods The yeast strain AH109 was transformed with AngRem104pGBKT7/c-myc and yeast-mating was utilized to screen for interacting proteins with AngRem104 in pretransformed human kidney cDNA library. The human embryonic kidney (HEK 293T) cells were transformed with two recombined plasmids,AngRem104-pcDNA3.1/V5-His and BBS2-pCMV/c-myc. Mouse anti-human V5 monoclonal antibody and mouse anti-human c-myc monoclonal antibody were used in immunoprecipitation and immunoblot analysis, respectively. Results Seven proteins that interact with AngRem104, including BBS2 were identified. The AngRem104-V5 and the BBS2-c-myc fusion protein were detected respectively in the immunoprecipitation by anti-c-myc and anti-V5 antibody. Conclusion The novel gene AngRem104 may interact with BBS2 protein in mammalian cells,which provides insights as to the function exploration of novel gene AngRem104 and the pathogenesis investigation of Bardet-Biedl syndrome.

Objective To evaluate the diagnostic value of multi-slice CTA(MSCTA) in cerebral aneurysms.Methods 15 patients with cerebral aneurysms were undergone MSCTA,of which,DSA were performed in 5 cases,and Gnglielmi detachable coil were performed in 2 cases . The images of 15 patients were processed with maximum intensity projection ( MIP ) , volume rendering ( VR ) and multiple planar reconstruction ( MPR ) .Results 16 cerebral aneurysms in 15 patients were found by MSCTA , the location of aneurysms was in the vertebral artery in 2,in the cerebral arterial circle in 5,in the anterior cerebral artery in 5 ,and in the middle cerebral artery in 3.DSA displayed 4 cerebral aneurysms in 5. 3D-CTA imaging and MPR combined with original transect images and multi-angle observation wereof great advantageous for diagnosis. The position, size and width of the fundus of cerebral aneurysms in 5 patients displayed by CTA wereaccordant with the results of DSA.Conclusion MSCTA can display cerebral aneurysms clearly. 3D-CTA combined with MPR and original images can make diagnosis more accurate and objective, and provide valuable information for surgery or interventional therapy.
