Rheumatoid arthritis ( RA) was a common autoimmune disease characterized with main clinical manifestations of chronic inflammation in joints.Anti-carbamylated proteins(anti-CarP)antibody, as a promising bio-marker, played a crucial role in the diagnosis of RA patients and the screening of pre-RA patients .In this article , recent progress on the study of anti-CarP antibody and RA related diseases has been reviewed , which was expected to provide new references for the diagnosis and treatment of related clinical diseases .

Objective To investigate the expression of c-erbB-2 in breast cancer and its relationship with prognosis.Methods The expression of c-erbB-2 in breast cancer was detected by immunohistochemistry assays in 60 cases of breast cancer.Results The positive expression level of c-erbB-2 in invasive breast cancer was signifi-cantly higher than that in other kinds of breast cancer(P<0.01).The positive expression level of c-erbB-2 in the metastatic breast cancer with four lymph nodes was higher than in the early cancer with no lymph node involvement (P<0.01).The 10 years survival rate in negative expression of c-erbB-2 was higher than in positive expression(P<0.05).Conclusion c-erbB-2 is important for physicians to instruct the treatment of the breast cancer and judge the prognosis.

Objective To determine whether preoperative embolization is a valuable adjunct to surgical excision of hemangioblastoma. Methods Eleven cases of hemangioblastoma, involving 8 of cerebellum , 1 of medulla oblongata and 2 of spinal cord shown by CT, MR and DSA were embolized preoperatively. The feeding arteries were catheterized with microcatheter and devascularized with polyvinyl alchol particles. Results The blood supplies of the tumor in 6 cases were completely eliminated, and partial occlusion through embolization were undergone for the other 5 cases. Surgical operation was undergone 1-7 days later with all, the 11 tumors totally resected acompanied by minimal blood loss and shortening of the operation time. In addition, manipulation and removal of these embolized tumors were actually easier than expected. No complications occurred during the procedures of embolization and operation. Conclusions Preoperative embolization of hemangioblastoma is a useful and relatively safe to surgical complete resection of this hypervascular tumor with significant reduction of blood loss and operation time.

AIM: To investigate the effect of purifried L-amino acid oxidase (LAO) from bungarus fasciatus snake venom on apoptosis and growth of HUVCE cell line. METHODS: The L-amino acid oxidase was purified by SP-sepharose HP column followed by Heperin-Sepharose (FF) column. The homogeneity of the preparation was examined by SDS-PAGE and the molecular weight of LAO was determined by SDS-PAGE and high performance liquid chromatography (HPLC) gel-filtration. The MTT assay was used to detect the viability of cells. Flow cytometry and laser confocal microscopy were used to identiyfy the cell cycle and apoptotic morphology after cells treated with LAO. RESULTS: An L-amino acid oxidase (BF-LAO) was successfully purified from the venom of bungarus fasciatus. It showed a single band in SDS-PAGE under both reduced and non-reduced conditions. The apparent molecular weight was determined to be 60 kD by SDS-PAGE and 70 kD by HPLC gel filtration. LAO inhibited growth and induced apoptosis of HUVCE cell line in a dose-dependent manner after 12 h incubation, with the 50% inhibitory concentration (IC_ 50 ) being of 2.8 mg/L. Flow cytometry and laser confocal microscope showed a typical apoptotic peak and morphological changes of these cells. CONCLUSION: The L-amino acid oxidase from bungarus fasciatus snake venom could inhibit the HUEVC cell growth and induce the cell apoptosis.

Chronic venous disorder (CVD) of the lower extremities generally induces dermatologic complications in lower extremity skin, such as hyperpigmentation. If not treated effectively, the lesions may develop into severe outcomes, including dermal ulcer or necrosis.

Objective To select valuable biomarkers for diagnosis and predicting outcome of sepsis-related acute respiratory distress syndrome(ARDS) from D-dimmer (DD),yon Willebrand factor (vWF),platelet (PLT),N terminal-pro brain natriuretic peptide (NT-ProBNP),interleukin-6 (IL-6),interleukin-8 (IL-8) and surfactant protein D (SP-D).Methods A total of 48 sepsis accompanied with ARDS patients and 40 sepsis patients were prospectively studied with comparison.The clinical characteristics of all the patients were recorded in detail.The blood samples were obtained within 24 hours of ICU admission.The concentration or activity of the seven biomarkers was quantitatively assayed and the results were recorded.To select the most valuable biomarkers as clinical indices,diagnosis model and death predictive model were constructed by Logistic regression.Results Among the seven candidate biomarkers,SP-D,vWF and IL-8 showed the most value.Their area under the receiver operator characteristic curve (ROC) were 0.758 (P ＜ 0.01),0.783 (P ＜ 0.01) and 0.747 (P ＜ 0.01) respectively,and raised to 0.847 (P ＜ 0.001) when the three biomarkers were combined.IL-8,age greater than or equal to 60 years and APACHE Ⅱ score greater than or equal to 20 were related to ARDS death with 12.138(lnIL-8)(P=0.022),6.157(P=0.040) and7.415(P=0.014) of OR values respectively.Conclusion SP-D,vWF,IL-8 should be valuable for early prediction of sepsis-induced ARDS and the diagnostic accuracy raised through combined utilization.IL-8 may be predictable for prognosis of sepsis related ARDS and the comprehensive evaluation combining clinical indices with IL-8 should be suggested in clinical practice.

Objective To investigate the diagnosis,preoperative examination and surgical treatment of carotid body tumor(CBT).Methods From December 2008 to December 2012 80 patients of carotid body tumor were treated in our center.The average age was(43:±:12)years,33 cases were male,47 cases were female.The lesions were unilateral in 68 cases and bilateral in 12.All tumors were surgically resected.In 26 of Shamblin Ⅰ,32 of Shamblin Ⅱ and 19 of Shamblin Ⅲ tumors were simply resected.One Shamblin Ⅱ and 2 Shamblin Ⅲ cases underwent tumor resection combined with external carotid embolization.3 Shamblin Ⅱ and 8 Shamblin Ⅲ cases were treated by tumor resection combined with internal carotid reconstruction,1 Shamblin Ⅲ was done with tumor resection combined internal carotid repair.Results All of 80 patients with 92 tumors were successfully resected.There was no death case during peroperative period,while one case developed hemiplegia and 14 cases suffered cranial nerve injuries.68 cases (85％) were followed-up from 1 year to 6 years.Thera were 14 patients with cranial nerve injuries,2 of them were lost to follow-up,11 with complete or partial recovery and 1 was still doing poorly.Conclusions Tumor size and its relation to the carotid artery form the basis upon which appropriate operation is adopted.

Objective To development a cooling crystallization process that is suitable for industrial preparation of purified dihydromyricetin.Methods Screen design was used to investigate effects of process parameters such as,temperature,concentration ethanol aqueous,quantity of activated charcoal and adsorption time on yield and purity of dihydromyricetin.Purity was verified by high performance liquid chromatography and thin layer chromatography.The solubility of dihydromyricetin in water at viable temperature and ethanol proportion was also determined by UV spectrophotometry.The solid form was characterized by thermal analysis and powder X-ray diffractometry.Results When temperature was ＞ 85 ℃,ethanol concentration ＜ 10％,dosage of activated charcoal 0.1％-0.3％,and adsorption time 1-3 min,yield of dihydromyricetin was more than 70％,and the purity greater than 98％.The crystals,prepared by cooling crystallization from water and ethanol aqueous,had the same physical form and crystal habit.Conclusion Cooling crystallization from low concentration of ethanol aqueous gets higher yield and the process is more robust than crystallization from water.
