Digestive diseases, are various types of frequently encounted clinical disorders .at present, diagnosis and differential diagnosis of digestive diseases , in addition to laboratory tests (biochemistry, immunology, cytology and bacterial genetics , etc.), to a large extent still rely on imaging studies.Flow cytometry is a function of the level of single cells or other biological particles for quantitative analysis and sorting means of detection , which can be tens of thousands of high -speed analysis of cells and can simultaneously from a cell a plurality of measured parameters , high speed, high precision, accuracy, etc., become the most advanced cellular quantitative analysis techniques .In recent years, flow cytometry is widely used in the diagnosis and treatment of gastrointestinal cancer , liver cirrhosis, Crohn′s disease, ulcerative colitis and other digestive diseases.

Inflammatory bowel disease ( IBD ) is a group of chronic non-specific inflammatory conditions of the intestine with unknown etiology.IBD has variety of intestinal manifestations and complications and there is lack of gold standard for diagnosis, so the disease should be diagnosed on the basis of clinical manifestations, endoscopic findings and histopathological examination.Most patients require surgical treatment and long-term maintenance of medication.Multi-disciplinary team (MDT), consisting of gastroenterologist, general surgeon, anorectal surgeon, nutritionist and psychologist, is needed for individualized treatment of patients.This article introduces the MDT model of diagnosis and treatment, and its application in inflammatory bowel disease.

Objective To analyze the corneal flap thickness in laser in situ keratomileusis(LASIK) using Moria M2 microkeratome and to identify the related factors. Methods Sixty patients with LASIK were divided into two groups: M2 90 group,using the Moria M2 90 microkeratome,n=30;M2 110 group,using the Moria M2 110 microkeratome,n=30.All were performed on both eyes with the right one treated first.Subtraction pachymetry was used to measure corneal flap thickness which was analyzed statistically with the data including age,preoperative corneal diameter,curvature,corneal thickness and refraction. Results In the 30 patients of M2 90 group,the mean corneal flap thickness of right eye and left eyes were(128.03?12.03)?m(105~156 ?m) and(123.40?12.38) ?m(92~147 ?m),respectively,and the corneal flap thickness were statistically different between the right and left eyes(P

Objective To investigate the effects of rapamycin on renal tissue and function of rats with protein overload nephropathy and to explore the protective mechanism of losartan. Methods Experimental rat models with protein overload nephropathy, induced by intraperiotoneal injection of BSA (2. 0 g/d)into female Wistar rats, were divided into three groups: control group, rapamycin group(injected intraperitoneally with rapamycin) and losartan group(injected intraperitoneally with rapamycin and given orally with losartan). At different time points, the quantity of 24-hour urine protein and renal function were measured, and the morphologic changes of renal tissues were evaluated by HE staining and electron microscope. Results Both at day 7 and day 14, rats received BSA developed intense proteinuria. At day 7, compared with control group, 24-hour proteinuria increased markedly in rapamyein group (P<0.05). Nevertheless,proteinufia was notably alleviated in losartan group (P<0.05). At day 14, 24-hour-urine protein of rapamycin group was also significantly higher than that of the losartan group (P<0.05), but therewas no significant difference between control group and losartan group (P>0.05). Proteinuria and intratubular albumin cast formation were alleviated notably in losartan group. The fusion of focal podocytes in rapamycin group was obvious in comparison with control group. Conclusions Rapamycin can agrravate proteinuria in rats with protein overload nephropathy through changing the barrier of glomerular filtration by damaging podocytes. Furthermore, losartan can alleviate severe proteinuria induced by rapamycin.

Objective To investigate the therapeutic effect of acupoint selection by heavenly stems on eosinophils(EOS) in guinea pigs with asthma.Methods Forty-eight guinea pigs were randomized into four groups: group A(timely electroacupuncture at the period of the day from 3 p.m.to 5 p.m.),group B(un-timely electroacupuncture at the period of the day from 9 a.m.to 11 a.m.),group C(model group) and group D(normal control group).Asthma was induced by chicken ovalbumin in groups A,B and C.The hematoxylin-eosin(HE) staining method and terminal-deoxynucleotidyl transferase-mediated nick end labeling(TUNEL) method were applied in the pathological and quantitative observation of eosinophils(EOS) in lung slices.Results The number of EOS was increased in model group(P

Objective To estimate the application for the rapid identification of common clinical bacteria by MALDI-TOF MS. MethodsFour hundred and twenty-six bacteria, including Salmonella spp strains collected from Zhejiang center for disease control and prevention were collected from blood, sputum,secretion and urine in 2nd Affiliated Hospital of Zhejiang University during December 2008 to August 2009. The isolates included 76 gram positive coccus and 350 gram negative bacilli. Species identification was performed with the Vitek system, and serotypes of Salmonella and Shigella were determined by serum agglutination test. 16s rDNA gene of 91 bacteria were amplified by PCR. The RCP products were sequenced. Then the results were compared with the reported sequences from GenBank. All strains were identified by MALDI-TOF MS. Results of three identification methods were compared with each other. Results Among 426 tested isolates, identification results from Vitek system and MALDI-TOF MS for gram positive coccus and 323 out of 350 gram negative bacilli (exception for Salmonella and Shigella spp.),were identical. For 23 Salmonella and Shigella spp. , only 2 Salmonella enterica subsp, enterica serovar Typhimurium were identified the same results by the three methods. Besides, results from Vitek system and serum agglutination test for 1 Salmonella enterica subsp, enterica serovar Typhi, 3 Salmonella enterica subsp.enterica serovar Paratyphi A, 1 Salmonella enterica subsp, enterica serovar Paratyphi B, 1 Salmonella enterica subsp, enterica serovar Enteritidis, and 1 Salmonella enterica subsp, enterica serovar Bovis-morbificans were consistent with that from 16S rDNA gene sequence. Four isolates which were confirmed as S. flexneri by Vitek system and serum agglutination test were identified as Escherichia coli by both 16S rDNA gene sequence and MALDI-TOF MS. ConclusionMALDI-TOF MS could be used for rapid and accurate identification of common clinical bacteria with good repeatabihty, excepting for the Salmonella and Shigella spp.

AIM: To investigate the apoptosis in primary gastric cancer cells induced by resveratrol, and the relation between this apoptosis and expression of bcl- 2 and bax. METHODS: In in vitro experiments, MTT assay was used to determine the cell gowth inhibitory rate. Transmission electron microscopy and TUNEL staining were used to quantitatively and qualitively detect the apoptosis of primary gastric cancer cells before and after the resveratrol treatment. Immunohistochemical staining and RT - PCR was used to detect the expression of apoptosis - regulated gene bcl - 2 and bax. RESULTS: Resveratrol inhibited the growth of primary gastric cancer cells in a dose - and time - dependent manner. Resveratrol induced primary gastric cancer cells to undergo apoptosis with typically apoptotic characteristics. TUNEL assay showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the apoptotic indexs were 4.93% ± 0.19%, 16.74% ± 0.43%, 27.88% ±0.36%, 36.84% ± 1.07 % respectively. Immunohistochemical staining showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the positive rates of Bcl - 2 proteins were 20.68% ± 0.49%, 10.84% ±0.33%, 6.80% ± 0.34%, 3.91% ± 0.15% and the positive rates of Bax proteins were 19.79% ± 0.98%, 30.74% ±0.85%, 40.14% ± 1.17%, 60.08% ± 1.64%. After exposed to resveratrol for 24 h, 48 h, 72 h and 96 h, the density of bcl- 2 mRNA decreased progressively with elongation of time and the density of bax mRNA increased progressively with elongation of time by RT- PCR. CONCLUSION: Resveratrol is able to induce the apoptosis in primary gastric cancer. This apoptosis may be mediated by down- regulation of Bcl- 2 and up- regulation of Bax.

The morbidity of colorectal cancer has been increasing year by year in China.Screening test of colorectal cancer can effectively decrease the morbidity and mortality of it.However,the current screening technique has obvious defect.Screening of exfoliated colonocytes isolated from human stool for early detection of colorectal cancer is noninvasive and well tolerated by patients;it has a potential for colorectal cancer screening.
