ObjectiveTo analyze clinical manifestations and treatment of eosinophilic gastroenteritis (EGE) in children.MethodsThe clinical data of 10 children with EGE under the treatment from June 2014 to June 2012 were analyzed retrospectively.ResultsThere were 10 children (6 males and 4 females) aged from 9 months to 14 years. Clin-ical symptoms of eight preschool and school age children included abdominal pain (8 cases), vomiting (4 cases), diarrhea (3 cases), ascites (3 cases), rash (3 cases), fever (2 cases) and hypoalbuminemia (2 cases). Clinical symptoms of two in-fant and toddler were diarrhea and hematochezia. Peripheral blood eosinophils were increased in 10 children. IgE was elevated in 9 children. One child had very high C-reactive protein. Endoscopic examination showed mucosal congestion, swelling, erythema, erosion. Multiple sites of biopsy showed eosinophil count> 20/HP. One child was diagnosed by lap-aroscopic exploration. The treatment included diet avoidance, omeprazole, anti-allergic drug. Four children were treated with corticosteroids. All children had been followed up for 6 months to 2 years. One child had relapsed.Conclusion The clinical manifestations of EGE are various. Endoscopic biopsy is necessary for diagnosis. Laparoscopy also is help-ful for diagnosis. Dietary and glucocorticoid therapy were effective.

Objective To examine the correlation between metabolic acidosis and malnutrition in maintenance haemodialysis (MHD) patients. Methods Forty-four MHD patients were divided into 3 groups according to plasma bicarbonate concentrations (PHCO3) and pH values. The correlation between metabolic acidosis and nutritional parameters was studied. Results The mean PHCO3 was (19.1?0.9) mmol/L in group A (n=13), (24.0?1.3) mmol/L in group B (n=22) and (27.1?0.1) mmol/L in group C (n=9). The adequacy of dialysis (Kt/V) was comparable in three groups. As compared with group B, group A had significantly higher body mass index (BMI), triceps skin fold thickness (TSF), dietary protein intake (DPI), normalized protein catabolic rate (nPCR) , Scr, serum K+ and parathyroid hormone (PTH), meanwhile, group C had significantly lower DPI, nPCR, Scr and albumin. There was no significant difference in plasma inflammatory markers C-reactive protein (CRP) among three groups. There was significant negative correlation of PHCO3 to nPCR (P

Objective To evaluate a new TNM staging system inclusive of intraperitoneal free cancer cells in terms of postoperative survival of patients with gastric cancer. Methods Free cancer cells (FCC) in the peritoneal washes of gastric cancer patients were estimated by measuring CEA mRNA levels using real-time RT-PCR. After 5-year follow-up, we get the cut-off value of CEA mRNA level by using MedCalc software to analyze the ROC curve. When CEA levels are more than the cut-off value, it may considered as FCC(+), and then using FCC(+) as distant metastasis (MI) to make a new TNM staging and analyze patients life-span. Results (1) Under the ROC curve analysis, when the cut-off value of CEA mHNA level was at 31.21 copies/ml, the Youden's index is the highest. (2) When FCC (+) considered as M1 to make a new TNM staging, the 5-year survival rate showed as below: Ⅰ-Ⅱ, P=0. 134; stage Ⅱ-Ⅲ P=0.004 and Ⅲ-Ⅳ P=0.022,repecetively. Conclusion (1) The best cut-off value of CEA mRNA levels for FCC in peritoneal washes is 31.2 copies/ml. (2) Our study demonstrated that application of FCC(+) in the TNM staging may have a better estimation of prognosis of patients suffering from advanced gastric cancer.

Purpose To improve the early correct diagnosis and avoid misdiagnosis of cervical mucinous adenocarcinoma.Methods Twenty-one cases of cervical mucinous adenocarcinoma were reviewed and analyzed retrospectively.The expression of CEA and Ki-67 was detected in the tumor by immunohistochemical staining (LABC method).Results Of the twenty-one cases, three cases (14.3%) were missed out, in which one was missed out by TCT and the others by biopsy; four cases (19.0%) were diagnosed by biopsy as adenocarcinoma in situ with invasion not be excluded, and then further confirmed as invasive adenocarcinoma by LEEP; one case (4.8%) was diagnosed as cervicitis at first and was further detected as adenocarcinoma by LEEP; twelve cases (57.1%) were directly diagnosed as adenocarcinoma by biopsy; one case (4.8%) was diagnosed as adenocarcinoma with unknown origin, and then as cervical adenocarcinoma after hysterectomy. Immunohistochemically, ten cases were CEA positive (47.6%) and the expression of Ki-67 was increased (>20%).Conclusions Understanding of the cytologic and histologic features of adenocarcinoma in cervix might improve its early detection and correct diagnosis, so that timely treatment is guaranteed for patients.

Objective To investigate the genotype distribution of extended-spectrum?-lactamases(ESBLs) and AmpC?-lacta- mases produced by Escherichia coli and Klebsiella pneumoniae in 10 teaching hospitals of China.Methods 90 clinical strains of E.coli and 61 strains of K.pneumoniae isolated in 2003 and confirmed to produce ESBLs were collected from 10 teaching hos- pitals in China.Analytical isoelectric focusing was used to measure the pI of the?-lactamases.Conjugation experiment was used to study the transfer of cefoxitin resistance.Plasmid-mediated AmpC enzyme genes were amplified and sequenced by multiplex polymerase chain reaction (MPCR).Results The prevalence of ESBL-producing E.coli and K.pneumoniae was about 50% in Wuhan,Nanjing and Jinan.The prevalence of ESBL-producing E.coli was lower than K.pneumoniae in Beijing.However,in other hospitals the prevalence of ESBL-producing E.coli was a little higher than K.pneumoniae.About 24.4% of ESBL-pro- ducing E.coli isolates and 19.4% of ESBL-producing K.pneumoniae isolates were resistant to cefoxitin.Cefoxitin-resistant i solate was identified in all hospitals except Shenyang.Major genotype of ESBL-producing isolates was CTX-M.The CTX-M-9 group was the most common group,followed by CTX-M-1.More K.pneumoniae isolates produced both ESBLs and AmpC en- zyme than E.coli.The genotype was CTX-M/DHA-1.The PCR results of 3 transconjugants producing both ESBLs and AmpC enzyme were the same as their donor isolates.Conclusions The genotype of ESBL-producing isolates is mainly CTX-M-9 group in these teaching hospitals.More K.pneumoniae isolates produced both ESBLs and AmpC enzyme than E.coli.Most of these isolates are due to geno type CTX-M/DHA-1,which can spread through plasmid.

This paper is to report the exploration of the activation of Rho/ROCK signal pathway in 5-HT-induced proliferation of rat pulmonary artery smooth muscle cells (PASMCs) and the inhibitory effect of m-Nis on this pathway. PASMCs were cultured with the explant technique. MTT assay was used to explore the proliferation of PASMCs after 5-HT treated for different time and the intervening effect of m-Nis. RT-PCR and Western blot were used respectively to explore the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 in 5-HT-treated PASMCs and intervening effect of m-Nis. The results of MTT assay suggested that 5-HT (1 µmol · L(-1)) treatment for 12-72 h significantly induced the proliferation of rat PASMCs (P<0.05 or P < 0.01), which were inhibited by m-Nis (1 x 10(-5), 1 x 10(-6), l x 10(-7), 1 x10(-8) mol · L(-1)) in dose-dependent manners (P < 0.05 or P < 0.01). Similarly, the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 were also inhibited by m-Nis in different degrees (P < 0.05 or P < 0.01). Thus, the results of this study suggested that Rho/ROCK pathway played an important role in 5-HT-induced proliferation of rat PASMCs, m-Nis inhibited 5-HT-induced proliferation obviously, which may be related to the blockage of Rho/ROCK signal pathway.

In order to reveal genetic diversity of domestic Andrographis paniculata and its impact on quality, genetic backgrounds of 103 samples from 7 provinces in China were analyzed using SRAP marker and SNP marker. Genetic structures of the A. paniculata populations were estimated with Powermarker V 3.25 and Mega 6.0 software, and polymorphic SNPs were identified with CodonCode Aligner software. The results showed that the genetic distances of domestic A. paniculata germplasm ranged from 0. 01 to 0.09, and no polymorphic SNPs were discovered in coding sequence fragments of ent-copalyl diphosphate synthase. A. paniculata germplasm from various regions in China had poor genetic diversity. This phenomenon was closely related to strict self-fertilization and earlier introduction from the same origin. Therefore, genetic background had little impact on variable qualities of A. paniculata in domestic market. Mutation breeding, polyploid breeding and molecular breeding were proposed as promising strategies in germplasm innovation.
