Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.

To observe the effects of Danshen-containing serum on SuFu and DYRK2 expression in the HSCs stimulated by leptin. SD rats (n = 60) were used to make danshen-containing serum by gastric perfusion for ten days with Danshen water decoction, normal saline and colchicine. The HSCs that were cultured in vitro would be stimulated for 24 hours by leptin (100 μg x L(-1)) except blank control group, after being intervened, the drug serum in each group would be cultured at 37 degrees C in 5% incubator. The cells would be collected after 24 hours, then the effects of danshen-containing serum on the proliferation of HSCs were detected by MTT, the expression of SuFu mRNA and DYRK2 mRNA were detected by RT-PCR, the expression of SuFu and DYRK2 proteins were tested by Western blot. Compared with blank control group, the expression of DYRK2 mRNA and DYRK2 proteins were enhanced obviously after stimulated the HSCs of rats by leptin (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, after cyclopamine group (Hh pathway inhibitor), Danshen-containing serum and colchicine were interfered, the expression of DYRK2 mRNA and DYRK2 proteins were decreased clearly (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were increased significantly (P < 0.01 or P < 0.05). Compared with model group, adding purmorphamine (Hh pathway agonist) to model group and making it activate could increase the expression of DYRK2 mRNA and DYRK2 proteins, but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, using the Danshen-containing serum to interfere the purmorphamine group could make the expression of DYRK2 mRNA and DYRK2 proteins decrease and the expression of SuFu mRNA and SuFu proteins increase significantly (P < 0.01). Danshen-containing serum would inhibition the activation and increment of HSCs by interfering the expression of SuFu and DYRK2 which were induced by leptin.

Caused by Helminthosporium carposaprum, tomato brown lea f spot was a serious disease in green house in Henan Province. The condition for promoting sporulation of fungi were tested in this paper. The results showed th at the number of sporulation were different on the different medium,the fungi c ould sporulate a lot on the PDA+tomato leaf and Czapek medium, but V8、PSA and t omato juice restrained sporulation.The best carbon source and nitrogen source f or the fungi promoting sporulation were fructose and ammonium chloride respectiv ely,mannitol and Peptone ammonium sulfate restrained sporulation. Light and ult raviolet radiation were in favor of sporulation , ultraviolet radiation irradiat ing for 60～80min promoted sporulation. The fungi were promoted sporulation on the condition of lower or higher temperature and alkalescence,which 15℃o r 30℃,pH 8～9.

OBJECTIVETo compare differences of clinical therapeutic effect of heat-sensitive moxibustion with different doses for irritable bowel syndrome (IBS).

METHODSSixty cases of IBS were randomly divided into a saturated-dose group (30 cases) and a traditional-dose group (30 cases). Heat-sensitive moxibustion was applied in both groups. The acupoints that had the strongest heat-sensitive feeling were selected and treated by warm and suspended moxibustion with moxa stick. Disappearance of heat-sensitive feeling was taken as the sign of treatment time in the saturated-dose group, while the traditional-dose group was treated for 15 min each time. The treatment in both groups was given twice a day for first 5 days, and from the sixth day it was given once a day for continuous 25 times, totally 30 days. Clinical symptom scores and therapeutic effect before and after treatment in two groups were observed.

RESULTSAfter the treatment, the cured and markedly effective rate was 75.0% (21/28) in the saturated-dose group, which was inferior to 44.4% (12/27) in the traditional-dose group (P < 0.05). The clinical symptom scores, including diarrhea, abdominal distension and pain, were obviously reduced in two groups compared with those before the treatment (all P < 0.05). Compared with the traditional-dose group, the symptom scores of diarrhea and abdominal distension in the saturated-dose group were obviously decreased (0.87 +/- 0.13 vs 1.27 +/- 0.21, P < 0.01; 1.12 +/- 0.41 vs 1.32 +/- 0.26, P < 0.05).

CONCLUSIONThe moxibustion featured with disappearance of heat-sensitive feeling and saturated dose has better therapeutic effect than that with traditional-dose for treatment of IBS. As individual dynamic amount of moxibustion, disappearance of heat-sensitive and quantitation varies from person to person, which is one of the key factors to obtain the best curative effect.

Objective To identify the polyreactivity of a monoclonal natural anti-keratin autoantibody 3B4 and to analyze its possible molecular me chanism.Methods enzyme-linked immunosorbent assay (ELISA)and immunohistoche mistry were applied to test the binding reactivity of 3B4 against different anti gens and tissues.The variable region genes and their amino acid composition wer e sequenced.Results 3B4 could reacted with a range of antigens and tissues,i n addition to keratin and skin.The variable region genes of its light chain and heavy chain showed high homology with germline genes VK1 am4 and VH1 J558.42.H CDR3 region,which mainly composed of short side chain amino acids(from 294 to 324 nucleotides around the heavy chain),was the only motif that differs from ot her highly homologous immunoglobulin genes.Conclusions The monoclonal natural anti-keratin autoantibody 3B4,with its variable region genes highly homologo us to germline genes,is highly polyreactive.The flexibility of HCDR3 may contr ibute to the polyreactivity.

Objective To investigate the clinical features of pneumocystis carinii pneumonia (PCP)in patients with autoimmune diseases.Methods The data from 12 patients with autoimmune diseases who were hospitalized in Peking Union Medical College Hospital because of developing PCP were retrospectively reviewed.Clinical characteristics and T cell subsets in the peripheral blood were analyzed.Results The main clinical manifestations of these 12 patients were fever(12/12),cough(9/ 12),expectoration(9/12)and obvious dyspnea(12/12),which were progressive.Blood gas analysis presented with typeⅠrespiratory failure.Bilateral interstitial and alveolar infiltrates were observed in chest X-ray film.The counts of peripheral blood lymphocytes(0.44?0.31)?10~9/L,CD4~+ T-lymphocytes (0.120?0.079)?10~9/L and CD8~+ T-lymphocytes were(0.248?0.252)?10~9/L decreased significantly and the CD4/CD8 ratio reversed,which were significantly different from those of healthy person(P
