Objective To study the feasibility and care mode of remote fetal monitoring at primary hospital. Methods A questionnaire survey was administered to 71 hospitals of different levels in Jiangsu province.Question-naire content included human resources status of midwifery,the remote fetal monitoring system and its clinical applica-tion;anonymous questionnaire survey was conducted to 130 maternal women by random cluster sampling;investigation of remote fetal monitoring device type,operation mode,clinical usage and existing problems was done through the doc-ument retrieval of VIP and Wanfang data platform.Results In grade Ⅱhospital,obstetricians sufficient and insuffi-cient were 10 cases (24.39%),31 cases(75.6%),respectively,and in grade Ⅲ hospital were 8 cases (61.53%), 5 cases (38.46%),respectively,there was statistically significant difference between grade Ⅱ and grade Ⅲ hospital (χ2 =4.572,P <0.05);In grade Ⅱ and grade Ⅲ hospital midwives were obviously insufficient,but there was no sta-tistically significant difference between grade Ⅱ and grade Ⅲ hospital(χ2 =0.219,P >0.05).Different cultural lev-el,place of residence,occupation of maternal demand for the development of remote fetal monitoring were urgent and higher degree of acceptance,but the cognition was not comprehensive,college degree or above,technical personnel and urban pregnant women that their need for remote fetal monitoring were the most urgent.There were significant differ-ences(all P <0.01).The use of remote fetal monitoring equipment was mostly at tertiary hospital nationwide.3G net-work way to transfer data had short time and small scope.Conclusion The existing monitoring system and service mode can not meet the requirements of the implementation of remote fetal monitoring,medical personnel professional quality and maternal comprehensive quality are the main influencing factors.The primary hospitals should actively pro-mote the application of remote fetal monitoring,maternal health care services and health education should arouse the attention of the whole society.

Objectives To identify and characterize 10 strains of Francisella philomiragia-like organisms isolated from blood samples and environmental water.Methods The 10 clinical and environmental isolates were identified by traditional morphological examination and biochemical characterization,matrix-assisted laser desorption/ionization time of flight(MALDI-TOF) mass spectrometry(MS) systems and sequencing based on 16S rRNA gene.The minimum inhibitory concentrations were tested by E-test methods.Results All the 10 isolates were gram-negative coccobacilli appearing tiny and faint counterstain of safranin,negative for urease,nitrate reduction and X and/or V factor requirement,but positive for oxidase and catalase.The isolates grew rapidly in sheep blood agar,chocolate agar and BCYE plate forming white opaque,colorless transparent or gray smooth colonies with about 2-mm diameters,but did not grow in M-H agar and MacConkey agar.The sequencing for 16S rRNA gene indicated that the 10 isolates shared more than 99.6％ similarity to Francisella philomiragia,and fell into the same clusters of Francisella philomiragia on phylogenetic tree.The MALDI-TOF MS analysis also showed the typical peaks with 6 153 m/z,5 180 m/z,7 757 m/z and 9 392 m/z which were similar to Francisella philomiragia ATCC 25015.However,they may be misidentified to be Sphingomonas paucimobilis by using Vitek 2 GN cards,Neisseria cinerea by using Vitek 2 NH cards,Myroides odoratimimus by using API 20NE strips and Haemophilus by using API NH cards.The results of antimicrobial susceptibility showed that they were all sensitive to chloramphenicol,doxycycline,tetracycline,gentamicin,ofloxacin and ciprofloxacin.Conclusion The 10 isolates could be identified as Francisella philomiragia,so we should pay more attention to the infrequent pathogen for its inactive biochemical reaction and the misidentification by commercial detection systems.

PURPOSE: Rebamipide is a propionic acid derivative that inhibits superoxide production and removes hydroxyl radicals. This study was performed to investigate the effects of adding rebamipide to semen, in an effort to determine if reactive oxygen species (ROS) production and lipid peroxidation of the sperm cell membrane as well as an improvement in seminal parameter and fertilizing capacity under oxidative stress was inhibited. MATERIALS AND MTHODS: Semen was collected from 30 normal healthy volunteers by masturbation after at least 48 hours abstinence. After liquefaction of the semen at room temperature, the prepared sperm was diluted with a sperm wash media to a uniform density of 20x106/ml. The semen was treated with 0.25ml of 0.2mM FeSO4 and 1mM sodium ascorbate for 60 min in the presence of various rebamipide concentrations (0, 10, 30, 100, and 300microM). ROS production, sperm motility, vitality, fertilizing capacity and the level of lipid peroxidation were analyzed by chemiluminescence, computer assisted semen analysis, eosin-nigrosin staining, a hypo-osmotic swelling test and the thiobarbituric acid method, respectively. RESULTS: Rebamipide at 100 and 300microM increased the sperm motility (p<0.05) but did not affect the sperm vitality. The ROS production and lipid peroxidation in the sperms treated with FeSO4/sodium ascorbate were inhibited by rebamipide in a dose-dependent fashion (p<0.05 in each). The total swelling rate of the hypo-osmotic swelling test was also increased by high rebamipide concentrations (100 and 300microM), respectively 49.2 17.9 and 50.8 21.7% (p<0.05). CONCLUSIONS: These results suggest rebamipide is an effective free radical scavenger and may be useful as an oral antioxidant in patients with male infertility due to increased ROS generation. However, further study to be possible the clinical use of rebamipide for improve the fertilizing capacity in male infertility is required.

To explore the role of regulatory peptides in the secretion of bronchial epithelial cells (BECs), we observed the effects of four peptides, i.e.vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the secretion of ILs from unstimulated or O3-stressed BECs. The results of the experiments showed that VIP exerted an inhibitory effect on the secretion of IL-1 and IL-8 from unstimulated and O3-stressed BECs, VIP also decreased the secretion of IL-5 from O3-stressed BECs; EGF promoted secretion of IL-1 and IL-8 from unstimulated BECs, but decreased the secretion of ILs from O3-stressed BECs; ET-1 and CGRP enhanced the secretion of IL-1, IL-5, and IL-8 from unstimlated BECs, CGRP also increased the secretion of ILs from O3-stressed BECs. The results obtained demonstrate that intrapulmonary regulatory peptides modulate the secretion of ILs from BECs, and may play an important part in transduction of inflammatory signals.

BACKGROUNDThe number of non-responders to cardiac resynchronization therapy (CRT) exposes the need for better patient selection criteria for CRT. This study aimed to identify echocardiographic parameters that would predict the response to CRT.

METHODSForty-five consecutive patients receiving CRT-D implantation for heart failure (HF) were included in this prospective study. New York Heart Association (NYHA) class, 6-minute walk distance, electrograph character, and multi echocardiographic parameters, especially in strain patterns, were measured and compared before and six months after CRT in the responder and non-responder groups. Response to CRT was defined as a decrease in left ventricular endsystolic volume (LVESV) of 15% or more at 6-month follow up.

RESULTSTwenty-two (48.9%) patients demonstrated a response to CRT at 6-month follow-up. Significant improvement in NYHA class (P < 0.01), left ventricular end-diastolic volume (LVEDV) (P < 0.01), and 6-minute walk distance (P < 0.01) was shown in this group. Although there was an interventricular mechanical delay determined by the difference between left and right ventricular pre-ejection intervals ((42.87 ± 19.64) ms vs. (29.43 ± 18.19) ms, P = 0.02), the standard deviation of time to peak myocardial strain among 12 basal, mid and apical segments (Tε-SD) ((119.97 ± 43.32) ms vs. (86.62 ± 36.86) ms, P = 0.01) and the non-ischemic etiology (P = 0.03) were significantly higher in responders than non-responders, only the Tε-SD (OR = 1.02, 95% CI = 1.01 - 1.04, P = 0.02) proved to be a favorable predictor of CRT response after multivariate Logistic regression analysis.

CONCLUSIONThe left ventricular 12 segmental strain imaging is a promising echocardiographic parameter for predicting CRT response.

OBJECTIVETo obtain egg yolk antibody in hen eggs laid by hens immunized with the protein of Porphyromonas gingivalis (Pg). To generate, purify IgY against Pg (anti-Pg-IgY) and identify its specificity.

METHODSPgATCC33277 was cultured under standard anaerobic conditions and harvested after proliferation. Then Pg was extracted by sonication until the cell pellets were shattered completely. After centrifugatiton, the supernatant was collected. Five-month-old Roman hens were immunized for egg antibody production. The antibody was inoculated intramuscularly and subcutaneously in the breast from multiple spot with 1.0 ml of a vaccine consisting of oil-adjuvant protein which was mixed with 1 ml protein of Pg and 1 ml Freund's adjuvant complete every 10 days, for 4 times. The eggs were collected after the first immunization and stored at 4°C. The anti-Pg-IgY was extracted and purified. The protein concentration was tested by bicinchoninic acid (BCA), the specificity of IgY analyzed by SDS polyacrylamide gel electrophoresis (SDS-PAGE), the titre of IgY and its physicochemical character were evaluated by indirect enzyme-linked immunosorbent assay.

RESULTSThe concentration of obtained anti-Pg-IgY was 2.05 g/L. SDS-PAGE analysis of the anti-Pg-IgY showed that the molecular weight of IgY was consistent with the theoretical value. Protein of anti-Pg-IgY appeared approximately 5 days after the first immunization, and reached the peak at 50 - 55 days. Antibody titres reached 1:100 000. Each egg produced more than 10 mg IgY, and its purification was up to 95% as well.

CONCLUSIONSLayer hens immuned by Pg may provide specific IgY of high titre and high concentration. The antibody has high purity and is heat, acid and alkali-resistant.
