Background:Gastric cancer is one of the malignant tumors with highest morbidity and mortality,and the early change of molecular marker in gastric mucosal lesion is the hot spot of gastric cancer study. Aims:To investigate the expressions and clinical significance of trefoil factor 2(TFF2),claudin 18(CLDN18),mucin 5AC(MUC5AC)in gastric mucosal lesions. Methods:Gastroscopy biopsies and surgery specimens from Dec. 2008 to May 2009 at Inner Mongolia People’s Hospital were collected,including 20 normal gastric mucosal tissues,20 intestinal metaplasia tissues,11 dysplasia tissues and 20 gastric cancer tissues. The protein expressions of TFF2, CLDN18, MUC5AC were determined by immunohistochemical SP method. Results:The positive expression rates of TFF2,CLDN18 and MUC5AC in normal gastric mucosal tissues were all 100% ,and were gradually decreased in the order of intestinal metaplasia,dysplasia and gastric cancer tissue,the differences were statistically significant(P < 0. 01). Conclusions:Expressions of TFF2,CLDN18 and MUC5AC protein are closely related to the degree of malignancy of gastric mucosal lesions,and can be considered as a potential biological marker for predicting the development and prognosis of gastric cancer.

Objective To evaluate the value of contrast-enhanced ultrasound in superficial lymphadenopathy. Methods Ninty-four superficial enlarged lymph nodes were studied by 2-dimensional, color Doppler ultrasound, and contrast-enhanced ultrasound. Then the contrast-enhanced images were analyzed by Philips Q-LAB software. All the results were compared with pathological diagnosis. Results For the 94 superficial lymph nodes examined,44 were benign,33 were metastases and 17 were lymphomas. The sensitivity, specificity,and accuracy of contrast-enhanced images were 84% ,74% and 790//oo respectively. Contrast-enhanced ultrasound examination showed intense homogeneous enhancement in 39 of 44 benign lymph nodes; high or low homogeneous enhancement in 25 of 33 and 7 of 33 in metastases respectively;intense homogeneous, and scarce enhancement in 6 of 17 and 9 of 17 in lymphomas respectively. Time-intensity curves showed that compared with metastasis lymph nodes and lymphomas, benign lymph nodes had higher peak intensity and larger area under the curve (P<0.01). Conclusions The diagnosis accuracy was significant increased when contrast-enhanced ultrasound was test against conventional ultrasound. The character of contrast agent enhancement and Q-LAB time-intensity curves provide valuable diagnosis information for differential diagnosis of benign,metastasis lymph nodes and lymphomas.

Total 149 strains of endophytic bacteria were isolated from different healthy organisms of Glycyrrhiza inflata Bat. from Xinjiang. The fermented liquids of these strains were screened by TLC and analysed by HPLC, and the glycyrrhizinic acid monoammonium salt was taken as standard control at the same time. Only one endophtytic bacterial stain of Bacillus subtilis could produce Glycyrrhizinic acid monoammonium salt analogue.

The present investigation was undertaken in order to select the surface-sterilization technique most efficient for eliminating epiphytes, to document endophytes of healthy tissues from Glaycyrrhiza inflat Bat. in Xinjiang. Surface sterilization with 5% commercial solution of sodium hypochlorite for 5 minutes was reaffirmed as adequate for removing epiphytes on licorice roots. From the 151 segments incubated, 149 bacterial isolates and 2 fungal isolates were obtained. From all the isolates, Bacterial isolates were identified by VITEK-AMS. Part of Bacteria were identified in 13 different genus. Fungal species were characterized as Penicillium sp. and Fusarium sp.with microscope.

Objective To study the clinical significance of fecal smear examination on diagnosing intestinal flora imbalance in infantile diarrhea.Methods A sterile cotton swab was used to spread a layer of fresh feces quantum satis from a sterile container on a clean slide;the smear was fixed and stained with Gram′s methods after it was air-dried,then the specimen was observed with a microscopy(field lens 100 ? eye lens 10) and recorded.Results In the acute diarrhea group(40 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 6 cases(15%),≥50% Gram-positive cocci in 30 cases(75%) and ≥68% Gram-positive bacilli in 4 cases(10%).In the delayed and chronic diarrhea group(62 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 7 cases(11.29%),≥50% Gram-positive cocci in 44 cases(70.97%) and ≥68% Gram-positive bacilli in 6 cases(9.68%).In the normal control group(32 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 1 case(3.13%),≥50% Gram-positive cocci in 1 case(3.13%),and ≥68% Gram-positive bacilli in 17 cases(53.13%).For the distribution of 3 floras in the 3 groups,chi-squared test was performed,and the results showed that the difference was significant in Gram-positive cocci(?~2=47.76 P0.05).Conclusions Acute,delayed or chronic diarrhea can lead to flora imbalance.In order to timely and rapidly know the flora imbalance in children with diarrhea,clinically the simple,easily operated and practical smear staining method shall be widely applied.

OBJECTIVETo investigate the potential of gene therapy of rat prolactinomas mediated by adenoviral vectors with a gene encoding rat tyrosine hydroxylase.

METHODSRecombinant replication-deficient adenovirus named Ad-GFP-TH with rat TH-cDNA and control adenovirus named Ad-GFP were constructed by homologous recombination in bacterial cells. The rat pituitary prolactinoma cell line MMQ are chosen as the target cells to study the effect of gene therapy on their growth and prolactin secretion mediated by Ad-GFP-TH.

RESULTSRecombinant Ad-GFP-TH and Ad-GFP were successfully reconstructed. Transfection of MMQ cells with Ad-GFP-TH not only restrained their growth but also decreased their PRL secretion.

CONCLUSIONGene therapy may serve for a potential treatment for prolactinomas, especially invasive prolactinomas.

To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.
