Forty rats were selected for the experiment, which were divided into three groups including experimental ulcer group, normal saline and normal control groups. The pancreatic tissue were prepared for immunohistochemical staining at 6th, 10th, 14th, and 21st day after operation. Sternberger's PAP method was used to show the glucagon cell (A cell) and insulin cell (B cell) in order to observe their changes during the experimental peptic ulcer. In normal control group, the percentage of A cells is 23.31?1.91 (X?SD) and that of B cells is 73.1?4.01. But in experimental ulcer group, the A cell percentage is raised up to 42.6?5.59 and the B cell percentage is lowered down to 57.5?4.55 on the 10th day after operation. Comparing with normal saline group and normal group their differences show statistical outstanding differences. The result may point out that both A and B cells of pancreatic islet take part in the body's natural resistance against the disease, especially A cells.

Objective To predict the risk of neonatal hyperbilirubinemia by transcutaneous bilirubin (TcB) nomograms and clinical risk factors.Methods Healthy term and late-preterm newborns (≥ 35 gestational weeks,and birth weight ≥ 2 000 g) born in Guizhou Maternal and Child Care Hospital between January 1,2013 and December 31,2013,were included.TcB levels were continuously recorded within 168 hours after birth.The value of hour-specific TcB nomogram combined with receiver operating characteristic (ROC)curves and Logistic regression model for predicting risk of hyperbilirubinemia was evaluated.Pearson's Chisquare test was also used for statistical analysis.Results A total of 5 250 cases were enrolled.TcB increased rapidly in the first 40 hours after birth,slowly increased between 40 to 96 hours,and reached a high level after 96 hours.Among them,the 95th percentile TcB stablized at 96 hours after birth.The 40th,75th and 95th percentile TcB peak levels were 173,217 and 248 μmol/L.Among the 5 250 neonates,there were 277 cases (5.3％) in the high-risk zone within 72 hours.The positive predictive value (PPV) was 22.02％;1 087 cases (20.7％) and 1 854 cases (35.3％) were in the medium-high risk and medium-low risk zones along with the PPV of 10.58％and 3.72％,respectively.There were 2 032 cases (38.7％) in the low-risk zone with the PPV of 1.38％.Multivariate analysis showed that the TcB high-risk zone after 72 hours was associated with gestational age,delivery mode,feeding mode and TcB level of risk zones within 72 hours.Compared to those born at ≥ 40 gestational weeks,those born at ≥ 37-＜40 gestational weeks were more likely in the TcB high-risk zone after 72 hours (OR=1.80,95％CI:1.29-2.51).The likelihood was reduced by 42％ among neonates born with cesarean section compared to those delivered vaginally in term of the TcB high-risk zone after 72 hours.Infants who received mixed feeding were less likely to be in the TcB high-risk zone after 72 hours when compared to breastfed infants (OR=0.51,95％CI:0.29-0.88).With the reduction of the high-risk zone level within 72 hours,the likelihood in the TcB high-risk zone after 72 hours was also decreased.ROC curve showed that the area under the curve (AUC) for predicting hyperbilirubinemia was 0.75 and its 95％CI was 0.72-0.78,with a sensitivity of 90.00％ and specificity of 40.00％.The AUC of a combination of predictive results obtained by the Logistic regression model with significant variables in univariate analysis and high-risk zone after 72 hours was 0.66,and its 95％CI was 0.62-0.69.AUC estimated by Logistic regression model according to the TcB levels of risk zones within 72 hours combining with clinical risk factors was 0.79,and its 95％CI was 0.76-0.82 (P＜0.01).Conclusions Hour-specific TcB nomograms of newborns in our hospital have been obtained,which facilitates the prediction and early intervention of neonatal hyperbilirubinemia.

Objective To investigate the relationship between the levels of intedeukin(IL)-6, IL-15 and endometriosis (EM). Method The levels of IL-6, IL-15 in the peritoneal fluid (PF) and serum of 74 patients with EM (EM group) and 46 patients without EM (control group) were measured by double-an-tibody ELISA. Results Higher levels of IL-6 in PF and serum were observed in EM group [(1017.81±361.98) ng/L,(455.47±161.52) ng/L]than those in control group [(284.63±70.50) ng/L,(149.37± 43.09) ng/L], and there was significant difference (P<0.01). The levels of IL-6 in PF and serum in EM group with stage Ⅲ-Ⅳ [(1253.44±189.63) ng/L, (556.50±93.34) ng/L]were significantly higher than those in patients with stage Ⅰ-Ⅱ [(582.81±107.75) ng/L, (268.96±63.48) ng/L](P < 0.01). There was positive relationship between the levels of IL-6 in PF and serum (r=0.950, P=0.01). The levels of IL-15 in PF in EM group [(333.45±63.94) ng/L]were significantly higher than those in control group[(203.85± 70.52) ng/L](P<0.01). No significant difference was found in the levels of serum IL-15 between EM group and control group (P>0.05). No significant difference was observed either in the levels of IL-15 in PF and serum between patients with stsge Ⅲ-Ⅳ and stage of EM Ⅰ-Ⅱ (P>0.05). Conclusions The increase of IL-6, IL-15 in PF may contribute to the development of EM. Serum IL-6 levels are of clinical diagnostic value in patients with EM.

Aim To test the skin healing and repairing efficacy and the mechanism of Hibiscus rosa-sinensis L bud extract by using the animal models. Methods KM mice were randomly divided into three groups:the model group, the positive control group, and the n-bu-tyl alcohol extract ( HrBN) group. Using the boils and carbuncles model, the healing condition of all the animals were observed. KM mice were kept in the SPF condition room and divided into five groups: the model group, the positive control group, and the low, middle, high dose groups. Using the full-thickness loss model, the repairing results of all the mice were ob-served. Through the antimicrobial test, the results of MIC and inhibition zone were obtained. The carbon clearance test was used to collect the blood at the time 5min and 15min, and get the liver and spleen, and the results of K andαwere obtained. Results In vivo ex-periments showed there was significant difference be-tween groups;the HrBN extract had the outstanding ef-ficacy in healing and repairing skin boils and full-thickness loss models. It had higher recovery rate than other ethanol extract, such as ethyl acetate extract and chloroform extract. In vitro experiments showed that the HrBN extract, ethyl acetate extract ( HrBE) ,AB-8 macroporous resin 30% alcohol part and 60% alcohol part had obvious antimicrobial efficacy. The carbon clearance test showed HrBN had a good effect in im-proving immune function, and it can increase the K and α. Conclusion HrBN in animal models exerts good skin healing and repairing efficacy, which might be related to its antibacterial activity and immunologic enhancement function.
