It is one of the key problems for the development of Chinese medicine to standardize the diagnosis of syndromes. The authors mainly discuss the ideas and methods of the study of standardization of syndrome diagnosis by retrospective analysis, also put forward the following suggestions: (1) the main ideas of this study should be based on the comparison of the diseases and their relevant syndromes and the predictive diagnosis of syndromes by the effects of herbal prescription treatment; (2) they are important ways to carry out multicenter, large sample and perspective clinical trials on the basis of the investigation and study of literature, consultation of experts and retrospective case review, and following the principles of clinical epidemiology, and to use the methods of evidence-based medicine to do systemic evaluation on the criteria of syndrome diagnosis; (3) they are important sectors of the study of standardization of syndrome diagnosis to enhance the objective studies on the four diagnostic methods of traditional Chinese medicine, and to do the functional studies under the conduction of systems biology; (4) Both data excavation technology and computer intelligence are the important technique supporting this study.

Along with the changes of disease spectrum, medical models and health concept, people pay more and more attention to the diagnostic and therapeutic approaches of traditional Chinese medicine (TCM). With the effect assessment being changed from disease-based model to patient-based model, how to scientifically and objectively explain the validity of TCM has become the premise for further development of TCM and dissemination of it throughout the world. In this article, the authors analyzed the status quo and problems of the effect assessment of TCM, and proposed some general methods for clinical effect assessment of TCM, including formulating criteria for syndrome differentiation under the guidance of TCM theories, paying attention to quality of life, proper selection of indexes for outcome assessment, application of modern clinical study methods, such as the methods of evidence-based medicine and clinical epidemiology, designing randomized controlled trials, multi-subject co-operation, strict supervision of the quality of researches, and establishment of organizations for professional training.

Objective To investigate the expression of heparanase in transitional cell carcinoma of bladder(TCCB) and its correlation with prognosis in bladder cancer.Methods The expression of heparanase protein and microvessel formation was assessed by immunohistochemical staining in 80 bladder cancer speci- mens resected at various stages of disease and 20 non-tumor bladder tissues (controls).Results The overall positive rate of heparanase in 80 cases of bladder carcinoma was57.5% (n=46),it was significantly higher than in non-tumor bladder tissues (P

Forty-eight patients with subclinical Cushing's syndrome(SCS)were evaluated.Eleven of them underwent adrenalectomy(Group 1)and the other 37 cases did not(Group 2).Serum and urine corticosol, plasma ACTH and parameters related to metabolic syndrome(such as waist circumference,blood pressure,blood lipids and fasting plasma glucose)were measured.The data at diagnosis were compared with those during the survey.The results indicated that patients with SCS had a significantly high prevalence of metabolic syndrome.The symptoms and signs of metabolic syndrome could be improved after removing the tumor.Otherwise there is no improvement,some patients will even develop into overt Cushing's syndrome.

Objective To study the relationship between efflux pump MexAB‐OprM and carbapenem resistance of Pseudomonas aerginosa strains .Methods The minimum inhibitory concentrations of imipenem and meropenem were determined by agar dilution method for 75 strains of P .aerginosa in the absence or presence of MC207110 to screen the phenotypes of active efflux pump .Reverse transcriptase‐polymerase chain reaction (RT‐PCR) method was used to determine the mRNA expression level of mexA which encodes the membrane fusion protein in active efflux pump MexAB‐OprM and the reference (housekeeping) gene rpoD .PCR method was used to amplify the regulatory genes mexR ,nalC ,and nalD of active efflux pump MexAB‐OprM in the strains overexpressing the efflux pump . The PCR products were subject to DNA sequencing and BLAST analysis . Results Of the 75 P .aeruginosa strains ,13 (17 .3% ) were positive for efflux pump MexAB‐OprM .Overexpression of the efflux pump was identified in 10 of the 13 strains and associated with positive regulatory genes mexR ,nalC and nalD .A Gly71→Glu mutation in nalC was found in 9 strains ,and a Ser209→Arg mutation in nalC was identified in 8 strains .Only one strain had a Thr158→Ile mutation in nalD .Eight strains had mutation in mexR .Conclusions Overexpression of multidrug efflux pump MexAB‐OprM plays an important role in carbapenem resistance of P .aeruginosa .High level expression of MexAB‐OprM is related to the mutations of its regulatory genes .

To study the distribution pattern of traditional Chinese medicine (TCM) syndromes in fatty liver disease.

The effect of amygdalin joint hydroxysafflor yellow A (HSYA) on the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and the possible mechanism were studied and explored. Chondrocytes were obtained from endplate of one-month SD rat intervertebral discs and cultured primary endplate chondrocytes. After identification, they were divided into normal group, induced group, amygdalin group, HSYA group and combined group. CCK-8 kit was adopted to detect the proliferation of the endplate chondrocytes. FCM was measured to detect the apoptosis. Real-time PCR method was adopted to observe the mRNA expression of Aggrecan, Col 2 alpha1, Col 10 alpha1, MMP-13 and the inflammatory cytokines IL-1beta. The protein expression of Col II, Col X was tested through immunofluorescence. Compared with the normal group, the proliferation of the endplate chondrocytes decreased while the apoptosis increased (P < 0.05). With down regulation of the mRNA expressions of Aggrecan, Col 2 alpha1 and up regulation of the mRNA expressions of Col 10 alpha1, MMP-13, IL-1beta (P < 0.05), the protein expression of Col II decreased while the protein expression of Col X increased. Compared with the induced group, amygdalin group, HSYA group, the combined group could inhibit the apoptosis and promote the proliferation (P < 0.05). They could increase the mRNA expressions of Aggrecan and Col 2 alpha1 while decrease the mRNA expressions of Col 10 alpha1, MMP-13 and IL-1beta (P < 0.05). They could also enhance the protein expression of Col II while reduce the protein expression of Col X. The effect of the combined group was significantly better than that of amygdalin and HSYA. Amygdalin joint HSYA could inhibit the degeneration of the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and better than the single use of amygdalin or HSYA.

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).

METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.

RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.

CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.
