Recently, the incidence of pediatric inflammatory bowel disease( IBD) is increasing. The diagnosis and treatment of IBD were focused by pediatric clinicians. The clinical features and treatment of pediatric IBD are dif-ferent,because of the growth and development. Growth deficiency and delayed puberty are unique symptoms. Children with IBD were treated with exclusive enteral nutrition as the first line treatment. The better treatment was formulated in accordance with the clinical features and nutritional therapy of pediatric IBD.

With the overuse of antibiotics,Clostridium difficile infections are increasing,and the incidence of refractory or recurrent cases increase.Increasing resistance to the traditional treatment(metronidazole and/or vancomycin),relapsing Clostridium difficile infection needs to seek new treatments.Fecal microbiota transplantation has been widely used in the treatment of adult Clostridium difficile infection,but is seldom used in children.In this paper,fecal microbiota transplantation for the treatment of Clostridium difficile infection in children related issues were reviewed.

To provide theoretical and practical basis for the successful formulation design of physically-mixed inhalation dry powder of proteins and peptides, related references were collected, analyzed and summarized. In this review drug micronization technology and commonly used carriers for inhalation dry powder preparation were introduced. For proteins and peptides, supercritical fluid technology and spray-drying are more suitable because of their capabilities of keeping drug activity. Being approved by U. S. Food and Drug Administration, lactose has been extensively used as carriers in many inhalation products. Formulation and process factors influencing drug deposition in the lung, including carrier properties, drug-carrier ratio, blending order, mixing methods, mixing time and the interaction between drug and carrier, were elucidated. The size, shape and surface properties of carries all influence the interaction between drug and carrier. Besides, influence of micromeritic properties of the dry powder, such as particle size, shape, density, flowability, charge, dispersibility and hygroscopicity, on drug deposition in the lung was elaborated. Among these particle size plays the most crucial role in particle deposition in the lung. Moreover, based on the mechanisms of powder dispersity, some strategies to improve drug lung deposition were put forward, such as adding carrier fines, adding adhesive-controlling materials and reprocessing micronized drug. In order to design physically-mixed inhalation dry powder for proteins and peptides with high lung deposition, it is essential to study drug-carriers interactions systematically and illustrate the potential influence of formulation, process parameters and micromeritic properties of the powder.

Objective: To establish the two-dimensional gel electrophoresis pH 4-7 maps of human gastric carcinoma and paired paracancerous mucosa,and to analyze differently expressed proteins of human gastric carcinoma and paired paracancerous mucosa.Methods: The total proteins of human gastric carcinoma and paired paracancerous mucosa were extracted,separated and analyzed by two-dimensional electrophoresis(2-DE).Results:By comparing and analyzing pH 4-7 protein expression maps of 5 cases of gastric carcinoma and paired paracancerous mucosa,128 differently expressed protein spots were detected,of which 56 expressed only in gastric carcinoma,27 in normal gastric mucosa tissues,32 more highly and 13 more lowly in gastric carcinoma than in paracancerous mucosa tissues. Conclusion: Proteins express differently in gastric carcinoma from paired paracancerous mucosa.Searching for differently expressed proteins between the two types of tissues may throw light on the molecular mechanism of gastric carcinoma.

Objective:To compare the mental health between the urban mothers and rural mothers of children with cleft lip and pal-ate.Methods:1 68 mothers(including 1 24 rural and 44 urban)of the children with cleft lip and palate were included in the trial group and 82 mothers of normal children were included in the control group.The subjects were tested by the self-assessment symptom lists of SCL-90 for the evaluation and comparison of mental health.Results:The scores of nine dimensions of trial group in somatization, forcing symptoms,depression,anxiety,etc were significantly higher than those of the control group(P <0.05).The scores of nine di-mensions of rural group in somatization,forcing symptoms,depression,anxiety,etc were higher than those of the urban group,the ri-val,psychotic and total scores showed significant differences(P <0.05);Conclusion:The mental health status of mothers of children with cleft lip and palate is poorer than that of those of normal children.That of the rural mothers is poorer than that of the urban ones. Special attention should be paid to the mental health status of the parents of children with cleft lip and palate.

Objective To investigate effect of lipid emulsion on cardiac arrest induced by bupivacain intoxication.Methods Forty SD rats were randomly devided into 2 groups.Group A applied epinephrine (n=20);Group L applied lipid emulsion combinding epinephring(n=20).The rats were administered Lupivacaine 20 mg/kg.Cardiopulmonary resuscitation(CPR) was started. Epinephrine 10 μg/kg were repeated three times followed by epinephrine 10 μg/kg every 5 minutes.Normal saline 5 ml/kg and 1 ml·kg-1·min-1 were administered in group A.20% Lipid emulsion 5 ml/kg and 0.25 ml·kg-1·min-1 were administered in group L.Heart rate,blood pressure, temperature were monitored.Blood gas analysiswere checked at 5 min,30 min after restoration of spontaneous circulation(ROSC).To record the number of successful CPR,time of ROSC and epinephrine dose.Results 11 rats(55%) and 16 rats(80%) were successful resuscitated.The success rate was higher in group L than in group A.Epinephrine dose was higher in group A than in group L.There was no difference in heart rate between the two groups.Systolic blood pressure and PaO2 was higher in group L than in group A(P<0.05).Conclusion There was better effect in lipid emulsion combined epinephrine than soly epinephrine when applied in cardiac arrest induced by bupivacaine intoxication.

Objective To study the relationship between placenta HBsAg in HBsAg positive pregnant women and serum hepatitis B virus (HBV) markers,HBV DNA levels in newborns.Methods Placenta HBsAg was detected by immunohistochemical affinity hormone-biotin complex (ABC) method in 155 HBsAg positive pregnant women.Serum HBV markers in newborns were detected by enzyme-linked immunosorbent assay (ELISA).Serum HBV DNA levels of newborns were detected by real-time fluorescence quantitative polymerase chain reaction (PCR).The positive rates were compared using x2 test.Results HBsAg was expressed with different levels in various types of cells of placenta in 155 pregnant women.The total placenta HBsAg positive rate was 37.4％ (58/155),and those in decidual cells,trophoblastic cells,villous mesenchymal cells and villous capillary endothelial cells were 37.4％ (58/155),25.8％ (40/155),18.7％ (29/155) and 7.1％ (11/155),respectively.The HBsAg positive rates of placenta gradually decreased from decidual cells of the maternal surface to villous capillary endothelial cells of the fetal surface (tendency x2 =43.01,P=0.00).The positivity of placenta HBsAg was associated with both HBsAg and HBeAg in newborns (x2 =4.88,P＜0.05 and x2 =3.86,P＜0.05,respectively),while that was not associated withanti-HBe and anti-HBc in newborns (x2 =3.36,P＞0.05 and x2 =0.00,P＞ 0.05,respectively).The risk of HBsAg positive in newborns was higher when HBsAg was positive in villous capillary endothelial cells and villous mesenchymal cells (OR=5.31,95 ％CI=1.38-20.40 and OR=3.33,95％CI=1.16-9.52,respectively).The risk of HBeAg positive in newborns was higher when HBsAg was positive in trophoblastic cells and villous mesenchymal cells (OR=3.04,95 ％CI=1.45-6.39 and OR=3.05,95 ％ CI=1.32-7.03,respectively).However,placenta HBsAg positive was not associated with HBV DNA positive in newborns (x2 =0.09,P＞0.05).Conclusion The risk of neonatal HBV serological markers positive is higher when the HBsAg positive placental cells are closer to fetal surface,which indicates that HBsAg enters fetal blood circulation by means of cell transferring layer by layer.

Objective To investigate the effects of different drugs and to explore the mechanism of pain in mice with adenomyosis ( ADM) .Methods The mouse model of adenomyosis was induced by oral administration of tamoxifen. The vaginal smear was examined by cytology, and serum levels of 5-HT, GnRH-R, NGF and NF were determined.Results Higher level of 5-HT was detected in the controls compared with the models.The expression of GnRH-R and NGF in nor-mal endometrium and eutopic endometrium were significantly lower than those in ectopic endometrium.The expression on NF in normal endometrium was significantly lower than that in the eutopic and ectopic endometria.Conclusions Similar with regular dose of GnRH-a, half dose of GnRH-a can slow down the progress of ADM as well as reducing pain.Combina-tion of regular dose of GnRH-a and Diane-35 could consolidate the therapeutic effect and even achieve pathological cure.5-HT may take an active part in the mechanism of pain in ADM.

Objective To investigate the changes and prognostic significance of bone marrow(BM) oil drop and megakaryocyte counts after chemotherapy in acute myeloid leukemia (AML) patients (non-M3).Methods Ninty-nine adult patients with denovo AML (non-M3) were retrospectively analyzed to evaluate the change of BM oil drop and megakaryocyte counts and their influences on overall survival(OS) and disease free survival (DFS) during all stages of standardized therapy.Results The median DFS and OS were 21 (2-88);months and 70 (4-89) months,respectively; and 3-year predicted DFS and OS were 47.3 ％ and 55.8 ％,respectively.After AML patients (non-M3) achieving complete remission (CR) by induction therapy,BM oil drop tended to increase along with postremission chemotherapy cycle accumulation, while megakaryocyte counts tended to decrease.The univariate analysis indicated that megakaryocyte counts decreased after the second course of postremission therapy. BM oil drop increased after the first to the third course of postremission therapy.Grade of myelofibrosis in BM biopsy,serum lactate dehydrogenase (LDH) level at diagnosis,flow cytometric immunophenotyping, the percentage of BM blast cells at diagnosis and the percentage of residual leukemic cells (RLC) during aplasia (7-10 days after the end of induction therapy) had prognostic significance.Multivariable COX analysis indicated the percentage of BM blast cells at diagnosis and change of BM oil drop after the third postremission therapy were independent prognostic factors for DFS (P =0.010,0.018 respectively),and RLCs during aplasia and change rate of the megakaryocyte counts after the second postremission therapy were independent prognostic factors for OS (P =0.009, 0.038respectively).Conclusion After AML patients (non-M3) achieving CR by induction therapy,BM oil drop tends to increase along with postremission chemotherapy cycles accumulation,while the megakaryocyte counts tend to decrease.Dynamic observations of bone marrow oil drop and megakaryocyte counts are helpful for assessing the prognosis of acute myeloid leukemia (non-M3).
