OBJECTIVE: To investigate the mechanism of in situ intestinal absorption of mangiferin in rats.METHODS: The in situ intestinal perfusion model was employed.HPLC/UV was developed to determine the concentration of mangiferin in intestinal circulated fluid.The effects of mangiferin concentration,bile and absorption site on the absorption parameters were studied.RESULTS:The mangiferin at a concentration from 5.0 to 25.0 ?g?mL-1 had no influence on the intestinal absorption kinetics(Ka) but it did at a concentration below 12.5 ?g?mL-1 in biliary duct-ligated rats.The absorption rate constants(Ka) in descending order were 0.164 h-1(ileum),0.132 h-1(jejunum),0.125 h-1(colon) and 0.107 h-1(duodenum),respectively.CONCLUSION: The absorption of mangiferin is in line with first-order kinetics with passive diffusion absorption mechanism.Mangiferin is well absorbed at all segments of intestine in rats,and bile is conducive to the increase of the permeability coefficient of Mangiferin in intestine.

Animal model plays an important role in prevention and control of infectious disease, which could link basic research in laboratory with clinical diagnosis and treatment for human patients.Mouse is the most widely used animal model of infectious disease, however, adult immunocompetent mice are resistant to some pathogens.The highly genetically diverse Collaborative Cross (CC) mice could recapitulate many of the genetic characteristics of an outbred population, such as humans.Based on this, this review will focus on the application and research progress of CC mice in infectious disease (including viruses, bacteria, fungi etc.), which could provide useful reference data for expansion of animal model resource bank, and implement of precision medicine of major and new emerging infectious diseases.We hope this review could serve as a modest spur to induce other researchers to come forward with their valuable contributions.

Objective:To assess the repeatability ( intraobserver comparison ) and reproducibility ( inter-observer comparison) of two different methods for establishing the occlusal plane on digital dental models. Methods:With Angle’ s classification as a stratification factor,48 cases were randomly extracted from 806 ones which had integrated clinical data and had their orthodontic treatment from July 2004 to August 2008 in Department of Orthodontics,Peking University School and Hospital of Stomatology. Post-treatment plas-ter casts of 48 cases were scanned by Roland LPX-1200 3 D laser scanner to generate geometry data as re-search subjects. In a locally developed software package,one observer repeated 5 times at intervals of at least one week to localize prescriptive landmarks on each digital model to establish a group of functional occlusal planes and a group of anatomic occlusal planes, while 6 observers established two other groups of functional and anatomic occlusal planes independently. Standard deviations of dihedral angles of each group on each model were calculated and compared between the related groups. The models with the five largest standard deviations of each group were studied to explore possible factors that might influence the identification of the landmarks on the digital models. Results:Significant difference of intraobserver varia-bility was not detected between the functional occlusal plane and the anatomic occlusal plane ( P>0 . 1 ) , while that of interobserver variability was detected ( P<0 . 001 ) . The pooled experimental standard devia-tion the 6 observers established for the functional occlusal plane was 0 . 2 ° smaller than that of the anato-mic occlusal plane. The functional occlusal plane’ s variability of intraobserver and interobsever did not differ significantly (P>0. 1),while the anatomic occlusal plane’s variability of the intraobserver was sig-nificantly smaller than that of the interobserver (P<0. 001),with a 0. 12° difference value of the pooled experimental standard deviation. Conclusion: When one observer measures a number of digital models, both the functional and the anatomic occlusal planes are suitable as a conference plane with equal repeatability. When several observers measure a large number of digital models,the functional occlusal plane is more reproducible than the anatomic occlusal plane,but the difference is small.

Objective To evaluate the secular trend of lung cancer mortality rate during 1981 to 2005 in Kunshan City. Methods The population-based registration data collected during the period of 1981—2005 were used to calculate the crude rate (CR), world age-standardized rate (WASR), five-year age-specific rate, truncated rate of those aged 35~64, cumulative rates of those aged 0~74, percent change (PC), and annual percent change (APC). The mortality rates by age, period/age, and cohort / age were analyzed and compared. Results The CR was 27. 88 per 100 000 on average, and was 43.19 per 100 000 for males and 12.56 per 100 000 for females, with a sex ratio of 3. 43: 1. The WASR was 22.52 per 100 000 on average, and 37.28 per 100 000 for males and 9.67 per 100 000 for the females. The truncated rate and cumulative rate of those aged 0~74 were 31.54 per 100 000 and 0.10% respectively. The PC and the APC were 144.56% and 4.08% for the crude mortality rate, and 23.57% and 1.01% for the age-standardized rate. Birth cohort and period data analysis showed rising of lung cancer of age-specific rate. Conclusion The mortality data demonstrated a rising trend in general in the period of 1981—2005 in Kunshan.

The outbreaks of Zika virus infection in different regions of the world underscore the potential for the virus to spread further in the Americas and beyond.Zika is a mosquito-borneFlavivirusand is transmitted by Aedes spp. mosquitoes.It is has been reported recently that Zika virus intrauterine infection causes fetal brain abnormality and microcephaly, and WHO encourages pregnant women in countries at risk MUST protecting themselves from mosquito bites. Until now, there is no imported case in China.We have established resource and technology storage to reply to the potentialZika cases in the future, therefore, people do not need to panic in China.

Objective To investigate the condition of self-management of patient controlled analgesia pump in patients in the ICU.Methods 82 patients in ICU were selected in July 2014 and were randomly divided into the observation group and the control group with 41 cases in each.In the observation group,the PCAP was fixed on the bedrails of patients' bed and controlled by themselves to acquire satisfactory analgesia effect.In the control group,the PCAP was operated by the nurses.Pains scores was compared between the two groups.Results The different position of PCAP showed the different scores of pain in the patients.The pain scores in the observation group (2.93±1.47) was significantly lower than that in the control group (3.76±1.36),P＜0.05.Conclusions Proper position of PCAP and controlled by patients can effectively reduce postoperative pain of patients in the ICU,and then reduce their suffering and improve their comfort.

Objective To obtain panorama X-ray images of the lower extremity with a simple method,eliminate the mosai-cing error,and apply this manual stitching technique for digital radiography to the measurement of the force line in total knee arthroplasty.Methods The track of X-ray tube was preset,and Dicom format data were collected by using digital X-ray ima-ging.Then,the data were imported to photoshop CS4 for manual image registration and image fusion.The reliability of the film was tested by comparing the vertical length of the body symbols proj ection in the coronal plane with that on the panorama X-ray (AutoCAD 2010)images.Moreover,the hip-knee-ankle angle was compared before and after operation.Results The matching sample t-test showed there were no significant differences in the length(4 groups of data)between the greater trochanter femur and the fibular head,and between the fibular head and the lateral malleolus between before and after operation(P>0.05 for all) .The hip-knee-ankles angle was much greater after operation than that before operation.Conclusion This manual stitching technique for digital radiography can produce seamless and precise panorama X-ray images,which can be used to reflect the length and angle of the lower extremity before and after operation.
