Objective To compare the clinical value of 2 oral contrast agents for magnetic resonance cholangiopancreatography(MRCP)and to investigate the safety,potency ratio of negative gastrointestinal contrast agents and to improve MRCP image quality.Methods Before MRCP,30 patients took oral ferric ammonium citrate(FAC)solution as group A and another 30 patients took Gd-DTPA dilution as group B.Then all patients underwent MRCP with T2-haste-fs-thick-slab sequence.Image assessment was done before and after oral taking of negative gastrointestinal contrast agents.Results After oral taking of negative gastrointestinal contrast agents,the interference of liquid in stomach and duodenum was suppressed and even effectively eliminated on MRCP.MRCP image quality was improved.Though the display of bile duct and pancreatic duct was of less image artifact,it reached the quality for diagnosis.No significant difference of MRCP image quality was found between those took FAC solution or Gd-DTPA solution.Conclusion FAC and Gd-DTPA both are effective negative gastrointestinal contrast agents.Gd-DTPA solution is of better function and higher quality-price ratio.

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

Objective To evaluate the immunogenicity and immunoprotective effect of heat shock protein 60 kDa (SjHSP60) of Schistosoma japonicum in mice after immunization and challenge infection, and explore the mechanism. Methods B cell/an?tibody?related databases and analysis tools were used to predict B?cell epitopes of SjHSP60. The mice were immunized with the recombinant SjHSP60 and challenged with S. japonicum cercariae. SjHSP60?specific antibodies in serum were detected by ELI?SA. The level of splenocyte proliferation was determined by 3H?TdR incorporation. Ex vivo suppression assay was performed to in?vestigate the effects of CD4 +CD25 + regulatory T cells (Tregs) induced by SjHSP60. Results SjHSP60 possessed multiple pre?dominant regions of B?cell epitopes. SjHSP60 induced a significant increase in both SjHSP60?specific IgG levels (P < 0.01) and splenocyte proliferation (P < 0.01) with a higher IFN?γ production (P < 0.01). However, the immunization with SjHSP60 resulted no significant reduction in adult worms (P > 0.05) and liver?accumulated eggs (P > 0.05) in S. japonicum?infected mice. Ex vivo assay showed that CD4+CD25+ Tregs from SjHSP60?immunized mice enhanced immunosuppressive activity. Conclusion SjH?SP60 has a dual role in host immune system, being involved in the induction of dominant humoral and cellular immune responses as well as in the enhancement of immunosuppression.

A patient recovered partial hand functions by 4 reconstructed digits based on a pair of complete defect hands that lost all of 10 digits on March, 2014. The thumbs were reconstructed with bipedal nail flaps combined with iliac bone, the right index finger and left middle finger were reconstructed with the 2nd toes of feet. Bilateral superficial circumflex iliac artery rerforator flaps (SCIPF) were taken to repair the donor areas of feet. According to the DASH-Chinese upper limb function score system, the function of both hands was obviously improved in six and a half years after surgery. The function of both feet was not significantly affected.

OBJECTIVETo study the effects of total alkaloids (TA) extracted from Rhizoma Coptis Chinensis on experimental gastric ulcer models.

METHODSFour kinds of experimental ulcer models were established respectively by water-immersion stress, intragastric ethanol, acetic acid erosion, and pylorus ligation. The anti-ulcer effects of TA were evaluated, and compared with that of berberine (Ber) and cimetidine (Cim).

RESULTSTA showed significant inhibitory effects on ulcerative formation induced by water-immersion stress, intragastric ethanol, and pylorus ligation in dose-dependent manner, and showed therapeutic effect on acetic acid erosion-inducing ulcer, in comparison with the control group. The anti-ulcer activity of Ber was less than TA containing equal content of Ber. TA significantly reduced the free acidity, total acidity and total acid output, but didn't affect the gastric juice volume, gastric pepsin activity, adherent mucus quantity of stomach wall and free mucus dissolving in gastric juice. The suppressive activities of TA on gastric acid secretion didn't occur when it was administered into dodecadactylon at a dose of 360 mg/kg wt. Moreover, when compared with Cim, the inhibitory effect of TA on gastric acid secretion isn't proportional to the inhibitory effects on the formation of the 4 kinds of experimental ulcers.

CONCLUSIONTA is a potent candidate in therapeutic drugs for treating gastric ulcer. Its anti-ulcer effective components and mechanism is not only related to Ber and inhibition of gastric acid, but also to other ingredients of TA and mechanism so far unknown.

Objective:To explore the efficacy and safety of ticagrelor versus clopidogrel in acute coronary syndrome (ACS) Chinese patients using glycoprotein Ⅱb/Ⅲa inhibitor (GPI).Methods:The data from CCC-ACS (Improving Care for Cardiovascular Disease in China-ACS) project were systematically reviewed in ACS patients with GPI. The patients were divided into ticagrelor and clopidogrel groups. A logistic analysis and propensity score matching (PSM) were performed to compare occurrences of major cardiovascular events (MACE) and bleeding events between the two groups during hospitalization.Results:A total of 63 641 ACS patients were collected from 150 hospitals. Logistic regression analyses showed that there was no statistically significant difference in the reduction of MACE between ticagrelor and clopidogrel when using GPI ( OR=0.881, 95% CI 0.599-1.296; P=0.521). However, major bleeding rate was higher in the ticagrelor group than that in the clopidogrel group ( OR=1.401, 95% CI 1.075-1.852; P=0.013). Similar results were observed after PSM. No statistic difference in MACE between the ticagrelor and clopidogrel group ( OR=0.919, 95% CI 0.613-1.376; P=0.681). Major bleeding rate was higher in the ticagrelor group ( OR=1.559, 95% CI 1.130-2.150; P=0.007). Conclusion:In ACS patients with GPI, ticagrelor did not reduce MACE, but increased the major bleeding risk compared with clopidogrel.

OBJECTIVETo study the effect of pregnancy-induced hypertension syndrome (PIH) on complications in very low birth weight (VLBW) preterm infants.

METHODSThe VLBW preterm infants were enrolled as research subjects, and according to the presence or absence of PIH in their mothers, they were divided into PIH group and non- PIH group. The incidence of major complications and length of hospital stay were compared between the two groups.

RESULTSThere were no significant differences between the two groups in gestational age, birth weight, sex, incidence rate of maternal diabetes, and use of antepartum hormone. The PIH group had a significantly higher rate of birth of small-for-gestational-age infants than the non-PIH group. The PIH group had a significantly lower incidence rate of bronchopulmonary dysplasia (BPD) than the non-PIH group, while there were no significant differences between the two groups in the incidence rates of apnea of prematurity, necrotizing enterocolitis, retinopathy of prematurity, and intraventricular hemorrhage-periventricular leukomalacia, and the length of hospital stay. There was no significant difference in the incidence rate of neonatal respiratory distress syndrome between the two groups, but the PIH group had a significantly lower proportion of infants who used pulmonary surfactant than the non-PIH group.

CONCLUSIONSPIH can alleviate respiratory complications and reduce the use of pulmonary surfactant and the incidence rate of BPD in preterm infants.

OBJECTIVEThe study was to reveal the vascular changes in three different supercharging flap models. From this study, we want to investigate which vessel, the artery or the vein is more important in elongating perforator flap survival and why.

METHODSTwelve rats were divided into three experimental groups. The left side flaps in all groups were pedicle using xiphoid perforator as control group. The right side flaps were supercharging experimental group. Group I, flap supercharged based on artery and vein of pubis perforator. Group II, flaps supercharged based on artery of pubis perforator. Group III, flaps supercharged based on vein of pubis perforator. Near-infrared fluorescent angiography was performed using SPY imaging system pre-and-aft operation and all angiography videos were compared and analyzed.

RESULTSShowed in angiography video of SPY, in control group and vein supercharging group, blood supply could be observed the immediately reducing, and almost be disappeared the amount of perfusion to distal area. It shows relatively constant necrosis in the distal side of control group and vein supercharging group, and the necrosis of vein supercharging group smaller than these of control group. In artery, vein supercharging group and artery supercharging group, blood perfusion could be observed separately perfusion in the upper and low area of flap. There are complete survival showed on the artery supercharging group and artery and vein supercharging group.

CONCLUSIONSThese findings indicated that congestive flap necrosis attribute to insufficiency of arterial blood. Arterial inflow was demonstrated more important for improved survival of distal flap than venous outflow.
