Taking an actual case as an example, this paper discusses how to integrate the informa-tization concept into the actual construction of the clinical skill center, and introduces the two aspects of the construction and management of the site and the daily business management. The design concept of multimedia standard room has been proposed, and the necessary teaching auxiliary facilities are chosen according to local conditions, all of which ensure the versatility and high cost performance of teaching units. Through the concept of information remote management, the problem of multimedia teaching terminal management is solved. Besides, through the information process reengineering, the daily business problems such as room management, multi-station examination and asset management have been solved, and syn-chronously a multimedia network learning platform has been built. The scheme has highlighted the charac-teristics of practical, efficient and management science and has achieved remarkable results, so it has cer-tain reference and promotion value.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).

METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.

RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).

CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.

ObjectiveTo investigate whether neuronal intermediate filament protein(NF-66) could be used as a molecular marker for the determination of malignancy of insulinoma.MethodsThe expression of NF-66 protein was detected in insulinoma and pana - cancerous tissues and 3 insulinoma cell lines by immunohistochemistry staining. The relationship between the expression of NF-66 protein and the clinicopathological characteristics,survival was analyzed by univariate and multivariate statistical analysis.ResultsExpression of NF-66 was found in 102(77％ ) out of 132 insulinomas and none of 98 paired control (P =4.86 × 10-31 ).NF-66 was highly expressed in 3 insulinoma cell lines.The expression of NF-66 was found in 96 (81％) out of 118 benign tumors (P =0.003),while out of 14 malignant insulinomas,6(43％ ) were found to express NF-66 ( P =0.003 ).The expression of NF-66 was significantly associated with tumor size (3 cm as the cut-off point),distant metastasis (38％ vs 81％,P =0.013) and distant plus lymph node metastasis (46％ vs 81％,P =0.009),respectively.The expression of NF-66 was not correlated with age,gender,recurrence and overall survival.ConclusionsDown-regulation of NF-66 was significantly associated with tumor malignancy,suggesting that NF-66 could be a potentially novel molecular bionarker to distinguish malignancy from benign insulinoma.

Subjective To acquire and analyze adult stage Schistosoma japonicum (Chinese strain) expressed sequence tags and new genes from an adult S. japonicum cDNA library, and to search new vaccine candidates and drug targets. Methods A cDNA library was constructed from adult stage S. japonicum. Clones were selected randomly from the cDNA library and were se-quenced. ESTs and new genes were acquired after analysis in GenBank databases by BLAST and other programs. All ESTs and new genes were submitted to GenBank and received accession numbers. Results 149 ESTs were acquired from a total 382 clones that were randomly selected from the adult S. japonicum cDNA library. All ESTs were successfully submitted to the dbEST at Genbank. Some of them were homologous with sequences of male, female, egg, schistosomula, cercaria and miracidia of S. japonicum. 18 new genes of adult S. japonicum were acquired. Some genes were housekeeping genes and some genes might be interesting as vaccine candidates or drugs targets. Conclusions The EST straltegy is a rapid, efficient and economical method to acquire ESTs and to discover new genes of adult stage S. japonicum from cDNA libraries.[

A 42-year-old woman was admitted to the hospital for an 11-month history of pustular lesions of the mouth and lips as well as a 5-month history of pustules,ulcer,proliferative plaques on the head,neck and trunk.She had suffered from 8 years of ulcerative colitis.Dermatological examination revealed mild erosion of eyelids,swelling of buccal mucosa and oral lips,as well as typical snail track lesions formed by pustules,exudates and mucilage.There was a large pitchy proliferative plaque sized 20 cm × 10 cm with an elevated margin in the neck as well as palm-to persian walnut-sized proliferative plaques in the prothorax,armpit,periumbilical area and left inguinal area.Histopathology revealed epitheliomatous hyperplasia of the epidermis with the formation of eosinophilic microabscesses,and superficial dermal infiltrate with numerous neutrophils and eosinophils.Direct immunofluorescence tests for IgA,IgG,and C3 were negative.A diagnosis of pyodermatitis-pyostomatitis vegetans was made.The patient was given intravenous methylprednisolone 40 mg/day and symptomatic treatment,which leaded to a gradual subsidence of skin lesions.

Objective: To summarize the characteristics of arrhythmia with the relevant factors affecting its prognosis in patients of apical hypertrophic cardiomyopathy (AHCM). Methods: A total 283 AHCM patients with echocardiography or cardiac magnetic resonance (CMR) conifrmed diagnosis in our hospital from 2005-01 to 2012-08 were summarized. The patients were divided into 2 groups: With arrhythmia group, n=103 and Without arrhythmia group,n=180. The endpoint event was followed-up by clinical and telephone visits in both groups and the relevant risk factors affecting AHCM prognosis were investigated by Cox regression analysis. Results: There were 269 patients ifnished the follow-up investigation, 98 in With arrhythmia group, 171 in Without arrhythmia group, and the death rate was 4.08% vs 1.17%, the occurrence of endpoint event was 18.37% vs 5.58%respectively. Cox regression analysis indicated that age (HR=23.051, 95% CI 1.08-1.068,P<0.005), left atrial diameter (HR=4.113, 95%CI 1.002-1.119,P=0.043) and NT-proBNP (HR= 18.653, 95% CI 3.433-26.650,P<0.005) were the independent risk factors affecting prognosis in AHCM patients. Conclusion: Arrhythmia is one of the common presentations of AHCM, it does not have much impact on survival, while it may cause ventricular ifbrillation and increase the occurrence of cardiovascular events.

This study examined endogenous cannabinoid (ECB)-anandamide (AEA) and its cannabinoid receptors (CBR) in mice liver with the development of schistosoma japonicum. Mice were infected with schistosoma by means of pasting the cercaria onto their abdomens. Liver fibrosis was pathologically confirmed nine weeks after the infection. High performance liquid chromatography (HPLC) was employed to determine the concentration of AEA in the plasma of mice. Immunofluorescence was used to detect the expression of CBR1 and CBR2 in liver tissue. Morphological examination showed typical pathological changes, with worm tubercles of schistosoma deposited in the liver tissue, fibrosis around the worm tubercles and infiltration or soakage of inflammatory cells. Also, CBR1 and CBR2 were present in hepatocytes and hepatic sinusoids of the two groups, but they were obviously enhanced in the schistosoma-infected mice. However, the average optical density of CBR1 in the negative control and fibrosis group was 13.28+/-7.32 and 30.55+/-7.78, and CBR2 were 28.13+/-6.42 and 52.29+/-4.24 (P<0.05). The levels of AEA in the fibrosis group were significantly increased as compared with those of the control group. The concentrations of AEA were (0.37+/-0.07) and (5.67+/-1.34) ng/mL (P<0.05). It is concluded that the expression of endocannabinoids AEA and its cannabinoid receptor CBR were significantly increased in schistosoma-infected mice. Endogenous endocannabinoids may be involved in the development of schistosoma-induced liver fibrosis.
