Chinese Pediatric Emergency Medicine 2013;20(3):231-235
Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) includes granulomatosis with polyangiitis,microscopic polyangiitis,eosinophilic granulomatosis with polyangiitis,which are known for this name because the common involvement of ANCA in the serum.New revise have been made in the Chapel Hill consensus conference 2012 about the nomenclature and definition of vasculitides,including the AAV.AAV can be misdiagnosed and delay diagnosed very easily for the variety and lack of specificity of clinical manifestations,and a early diagnosis and timely treatment is the key for a better prognosis.

Intervertebral disc degeneration (IVDD) takes great affection on people health all over the world.With the extension of human life and aging,the number of sick people will grow rapidly.At present,both conservative and surgical treatment can only alleviate the symptoms,rather than the fundamental treatment for the process of degeneration.Therefore,the application of cell therapy in the treatment of degenerative disc regeneration is an innovative treatment.However,it's a great bottleneck for exogenous transplanted stem cells to survive in degenerated intervertebral disc with harsh environment containing strong force,acidic pH,hypoxia,hyperosmolarity and limited nutrition.In recent years,tissue endogenous repair has been demonstrated to be present in almost all human tissues,and endogenous stem cell play an important role in the process.Similarly,nucleus pulposus was also confirmed the existence of such a kind of tissue specific stem cells-nucleus pulposus derived stem cells (NPSCs)-a new promising candidate for the treatment of IVDD.NPSCs,as a new kind of stem cells,hold either the characteristic of stem cell and the special potential of themselves,such as the nice adaption of the environment in intervertebral disc and the superior potential of cartilage differentiation.Nonetheless,the isolations of NPSCs were different;cell phenotypes were lack of wildly acceptable standard and the biological characteristics were various among different NP sources.In addition,whether the application of NPSCs could be used in nucleus pulposus tissue engineering still calls for further research.Due to the unclear in degeneration mechanism of IVDD,the study on degeneration mechanism of NPSCs may play a great important role in clarifying this issue.

This study was aimed to establish the ultra high performance liquid chromatography (UHPLC) fingerprints of Psoralea corylifolia L. The separation was achieved on a Shim-pack XR-ODS Ⅲ column (50 mm í 2.0 mm, 1.6μm) by gradient elution with acetonitrile-0.2% glacial acetic acid solution as the mobile phase. The flow rate was 0.1 mL·min-1 and the measurement wavelength was 246 nm. The temperature of the column was 45oC. The results showed that the UHPLC fingerprint of P. corylifolia L. was established and 10 characteristic common peaks were found, among which 6 peaks were recognized by comparing with reference substances. It was concluded that the method was rapid, reliable and reproducible. The established fingerprint can provide references for the study of sub-stance basis and quality control of P. c orylifolia L.

ObjectiveTo observe the effect of continuous elastic outside distraction on female minipig nipples and their supporting tissues,and to investigate its mechanism to correct inverted nipples.MethodsThree female 3-month-old minipigs with 12 nipples were employed.4 nipples of each minipig were remained without distraction as control group,and the other 8 nipples were continuously distracted with inverted nipple correction instruments.Corresponding nipples were excised at 2,4,8 and 12 weeks after traction.Before excision,the diameters and heights of nipples were measured with a vernier caliper.Then the excised nipple specimens were employed for HE staining to observe the change of their tissue structure and the number counting of capillaries.ResultsThe volumes of nipples all obviously increased after traction,as compared with control group,and diameters and heights of nipples were significantly different (P<0.01).In addition,there was a trend that nipple height increased with traction time.Under light microscope,the traction group showed that epidermis thickened,basal cells,fibroblasts and capillary significantly proliferated.Capillary counts compared with the control group were significantly different (P<0.01).ConclusionsContinuous elastic outside distraction can promote the proliferation of female minipig nipple and areola papillaris.

Objective:To obtain some effective objective markers used to predict the early liver metastasis of colorectal tumor,the relationship of liver metastasis of colorectal tumor with associate detection three markers such as CK20mRNA、CD44V6 and PCNA was studied. Methods:The expression of CK20mRNA in portal venous blood from 30 colorectal cancer patients was detected by fluorescent quarto RT-PCR,and the results of CD44V6 and PCNA in colorectal cancer tissue were determined by means of immunohistochemistry, and then compared with control groups through statistics analysis. Results:The rate of positive expression of CK20mRNA in colorectal cancer patients' portal venous blood was obviously superior to the level of benign pathological changes controls(P

Objective To investigate the effects of different surgical modalities on primary anorectal malignant melanoma. Methods Clinical data of 60 primary anorectal malignant melanoma cases who were admitted between 1965 and 2007 were collected, summarized and analyzed. Multivariate analysis was performed using the COX proportional hazards regression method. Results Tumors located in the rectum in 50 cases, in the anal canal in 10 cases. The overall survival rates were not significantly different between the 23 cases who received tumor resection only and those 30 cases receiving postoperative adjuvant therapy (X2=0. 078, P>0.05). Among these 53 surgical cases of anorectal malignant melanoma, 37underwent abdominoperineal resection, 16 underwent wide local excisions, There was no significant difference of the survival rates between the two groups (X2=1.464,P>0.05). Risk factors analysis revealed that the depth of tumor invasion is a risk factor (P<0.05), the modality of treatment is a protective factor (P<0.05). Conclusions Surgical operation is the principal effective management for anorectal malignant melanoma, Wide local excision is the principal therapeutic choice for localized well-circumferential anorectal malignant melanomas.

Objective Aim to explore the effect of hyperglycemia on the expression of glucose transporter 1 (GLUT-1)in rats at the acute phase of traumatic brain injury.Methods Adult male SD rats were randomly divided into 3 groups: normal control group, traumatic brain injury group and insulin treated group.The blood glucose concentration of the rats was measured before and after injury.The expression of GLUT-1 gene and protein in the injured and uninjured cortex was detected by reverse transcription polymerase chain reaction (RT-PCR) and western-blot.The apoptosis in the injured and uninjured cortex were detected by TUNEL staining.Results The blood glucose concentration increased markedly in traumatic brain injury group.The expression of GLUT-1 gene and protein in the injured cortex decreased in both the traumatic brain injury group and the insulin treated group.In contrast, the expression of GLUT-1 gene and protein significantly increased at 12 h, 24 h, 48 h, 72 h after injury in the insulin treated group compared with control(P<0.01).The number of apoptotic cells in the insulin treated group were significantly larger than that in the traumatic brain injury group at each time point(P<0.01).However, The number of apoptotic cell death remained unchange in the uninjured cortex in each group(P>0.05).Conclusions The hyperglycemia after traumatic brain injury may increase the apoptotic cells in the injured brain through decreasing the expression of GLUT-1.
