Objective Objective To study the application of oral ranitidine to MRCP. Methods 20 healthy subjects, including 12 males and 8 femals, were performed with random double-blind MRCP examination by 1.5T MR machine. Two experienced radiologist assessed the results. Results Without any side effect, the proximal end and distal end of the common bile duct, bile-cyst were displayed well (P

To discuss the immune mechanism of the acupuncture and moxibustion on allergic rhinitis(AR),which resulted from the summary of the immune mechanism research on AR in the last more than ten years,so as to improve diagnosis and treatment of the acupuncture and moxibustion on AR.To analyze and summarize the immune mechanism of the acupuncture and moxibustion on AR,which based on the data about that in the last more than ten years.

Multi-drug resistance (MDR) of cancer cells is a major cause of failure of chemotherapy in cancer treatment. Most MDRs are caused by overexpression of P-glycoprotein (P-gp) which effuses chemotherapeutic agents out of cells. Nano drug delivery systems (NDDS) have been valued for their characteristics including drug targeting, slow-releasing, and long circulation time in the body. Through mechanisms such as non-specific endocytosis and receptor-mediated endocytosis, NDDS can inhibit P-gp at the gene and protein level, leading to improved concentrations of chemotherapeutic drugs in cancer cells, and therefore reverse MDR.

The authors analyzed the current predicament of medical human resources and seek the deficiencies and problems that exist in the medical moral education system .Based on this , this paper pointed out that it should change the medical ethics education ideas , enhance medical ethics cultural identity; based on the health industry demand , broaden the content of the medical ethics education;to develop a new mode of medical ethics education , perfect the evaluation system of medical ethics and health industry demand , provide new guidance for medical eth-ics education .

Since 2007,in order to comply with the hospital's strategic development and construction of the subjects,our hospital treat the research project management as the starting point,through the establishment of a sound project management and funding approaches; strengthen project process management,implement the total quality control; use of information technology tools to improve project management effectiveness.After several years of implementation,the number of our hospital's research projects above provincial and ministerial level has gradually increased,manyhigh level of SCI papers are emerging,and discipline construction has also been effectively carried out,all of which have promotedour research strength,the development of medical teaching and research.Therefore,we will continue to strengthen project management,and fully mobilize the initiative staff awareness of service,make full use of scientific information systems in future scientific research management to boost hospital disciplines.

Objective To observe the effects of camellia oil on the development of allergic contact dermatitis in mice. Methods Mice models of allergic contact dermatitis were established with dinitrofluo-robene (DNFB). Then, certain concentrations of camellia oil and halcinonide were used topically on the ears of mouse models twice daily for 6 days. Skin specimens were obtained from the treated ears and subjected to histology examination and pathological analysis. RT-PCR was performed to detect the mRNA expressions of interleukin 2 (IL-2) and interferon γ (IFN-γ) in the skin tissues. Results Allergic contact dermatitis was successfully induced by DNFB in mice with a marked increase in the mRNA expression of IL-2 and IFN-7. There was a slight decrease in the ear swelling degree, inflammatory reaction intensity, number of infiltrating inflammatory cells, and pathological severity in camellia oil-treated mice and halcinonide-treated mice compared with glycerinetreated mice. Camellia oil and halcinonide also induced different degrees of reduction in the mRNA expression of IL-2 and IFN-γ in inflammatory tissues. Conclusion Camellia oil can alleviate the pathological damage and down-regulate the expression of IL-2 and IFN-7 in mice with DNFB-induced allergic contact dermatitis.

Objective To study the clinical characteristics, the outcome of pregnancy and the risk factors of uteroplacental apoplexy complicating severe placental abruption. Methods A retropectively study of the 52 cases of placental abruption who had delivered in our hospital from Jan. 2002 to Dec. 2006 was conducted. These cases were divided into 2 groups: 17 cases of uteroplacental apoplexy complicating placental abruption as observation group, the others with no uteroplacental apoplexy as control group. The risk factors of disease, clinical characteristics and the outcome of pregnancy between the two groups were compared. Results (1)The incidence of placental abruption was 0. 15% (52/35 049) among the total deliveries patients with uteroplacental apoplexy complicating placental abruption took up 0. 05% (17/35 049) of all deliveries and 33% (17/52) of all abruption cases. (2) General information and delivery : There were no significant differences ( P > 0. 05 ) regarding their mean age and BMI in two groups. All women in observation group had C-section delivery, which were 21 in control group. 14 women had vaginal delivery. The incidence of premature labour was 88% ( 15/17 ) in observation group, and 49% (17/35 ) women in control group delivered after 37 weeks. Significant differences were observed regarding delivery methods and gestational weeks(P <0. 01 ). (3)Risk factors: the incidence of preeclampsia, 71% (12/17), and the duration of disease, 6. 4 hours, in observation group were more than those in control group, 20% (7/35) and 4. 2 hours( P < 0.01 ). There were no significant differences between two groups in premature rupture, polyhydroamnions ( P > 0. 05 ). (4) Clinical characteristics in two groups : bloody amniotic fluid, fetal distress, hematometra and postpartum hemorrhage occurred in 82% (14/17) vs 26% (9/35), 65%(11/17) vs 29% (10/35), 35% (6/17) vs 6% (2/35), and 59% (10/17) vs 11% (4/35), with a significant difference (P <0. 01), but no statistical difference existed between indices such as abdominal pain, vaginal bleeding and abdominal tension ( P > 0. 05 ). (5) Placenta sites and abruption areas: placenta sites were distributed from anterior or posterior of uterine body 5/17 vs 24/35 , the fundus or cornu of uterus 12/17 vs 11/35 ( P < 0. 01 ). All cases in observation group presented abruption areas> 1/3, and 9 cases ≥2/3, 27 cases abruption areas < 1/3 and 8 cases abruption areas 1/3 -2/3 in control group (P<0.01). (6) Other complications and outcome: Hemorrhagic shock 3 vs 0, DIC 3 vs 0, hysterectomy 1 vs 0, intrauterine fetal death 3 vs 2, neonatal asphyxia 8 vs 5 and neonatal death 1 vs 0. There were significant differences ( P < 0. 01 ) between the two groups. Conclusions Preeclampsia, long duration of disease and fundal or cornual placenta a risk factors for uteroplacental apoplexy complicating placental abruption, which may lead to a poor maternal-fetal prognosis.

AIM　to compare the bioavailability and pharmacokinetics of two acyclovir tablets. METHODS　Concentrations of acyclovir in 10 men serum after po 600 mg of two acyclovir tablets were determined , in random 2-way crossover design. Pharmacokinetic parameters were also estimated. RESULTS　The peak concentrations of test and reference tablets were 1.24±0.49 and 1.17±0.20 μg/ml, the AUC 7.56±1.80 and 7.56±2.10μg*h/ml, respectively. The relative bioavailability was 101.36%±11.62%. The test formulation was found bioequivalent to the reference in AUC and Cmax by two one-side t test. CONCLUSION　Two tablets were bioequivalent.
