[Objective] To investigate the relationship between the body constitution and the syndromes of the bronchiectasis patients and provide the basis for the clinical treatment.[Methods] Col ected 80 out-patients and in-patients of bronchiectasis in the first affiliated hospital of Zhejiang Chinese Medical University from May 2011 to March 2012. Al patients met with the inclusion criteria, adopted the standardization of physical scale for physical identifica-tion and dialectical type and analyzed the relationship between constitution and syndrome.[Results] ①The gentleness type, qi-deficiency type and yin-defi-ciency type were more popular in the bronchiectasis, fol owed by the phlegm-wet type, wetness-heat type, yang-deficiency type and qi-depression type. The special inherited type and blood-stasis type were very rare. ②The syndrome of phlegm heat obstructing lung was the top one in the Chinese tradi-tional medical syndromes(48.75%).The frequency of liver-fire attacking lung syndrome, hyperactivity of fire due to yin deficiency syndrome and qi-yin de-ficiency syndrome were 21.25%, 18.75% and 11.25% respectively. ③From different body constitution distribution of TCM syndromes in patients with bronchiectasis, it could be found:gentleness type, qi-deficiency type, yang-deficiency type, phlegm-wet type and wetness-heat type were most presented as phlegm-heat stasis lung syndrome. Patients with qi-deficiency type were most presented as qi-yin deficiency syndrome .Patients with Yin deficiency type were always performed as hyperactivity of fire due to yin-deficiency syndrome. Patients with lung qi-stasis type were liver-fire invading lung syn-drome.[Conclusion] Phlegm-heat stasis syndrome was the main syndrome in patients with bronchiectasis. It conformed to the pathological characteristics of deficiency essence with virtual reality. Different body constitutions decided the different traditional Chinese medical syndromes after the disease onset.

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

BACKGROUND: At present, the relationship between diabetic nephropathy and osteoprotagerin remains poorly understood. OBJECTIVE: To investigate the correlation between bone mineral density (BMD) and serum osteoprotagerin changes in patients with 2 type diabetic nephropathy. METHODS: Totally 104 patients with 2 type diabetes were divided following 5 groups according to glomerular filtration rate: simple diabetes, mild renal injury, moderate renal injury, severe renal injury, and renal failure groups. Additional 20 healthy people were selected as the control group. The level of serum osteoprotegerin was measured by ELISA. Meantime, levels of serum calcium, phosphonium, alkaline phosphatase, creatinine, urea nitrogen, and glycosylatad hemoglobin were measured by. the automatic biochemistry analyzer. The bone mineral density of entopic L_(2-4) was determined by dual X-ray bone density equipment. The whole data was analyzed by multiple regression correlation analysis. RESULTS AND CONCLUSION: The level of serum osteoprotegerin in patients with diabetic nephropathy was obviously greater than that of the healthy people (P < 0.05), but BMD of the mild renal injury, moderate renal injury, severe renal injury, and renal failure groups was obviously lower than that of the healthy people (P < 0.05). Generally, the worse renal function accompanied by higher osteoprotegerin level, and lower BMD. There was a negative correlation between ostaoprotegerin level and BMD in patients with diabetic nephropathy (r=-0.497, P < 0.01). However, the relationships between osteoprotegedn level and diabetic duration (r=0.566, P < 0.01), serum creatinine level (r=0.772, P < 0.01), serum urea nitrogen level (r=0.708, P < 0.01), serum phosphonium level (r=0.329, P < 0.01), or serum intact parathyroid hormone level (F=0.702, P < 0.01) were positive. Meantime, the serum phosphonium level had negative correlation to serum calcium level (r=-0.505, P < 0.01). it demonstrated that when the renal function got worse in diabetic nephropathy patients, the serum osteoprotegerin level was increasing accompanied by BMD decreasing. The osteoprotegerin level presents a negative correlation to BMD and serum calcium level, but positive to diabetic duration, serum creatinine, serum urea nitrogen, serum phosphonium and serum intact parathyroid hormone levels.

BACKGROUND: In the field of intervertebral disc tissue engineering, seed cells primarily consist of nucleus pulposus cells (NPCs) and mesenchymal stem cells (MSCs). NPCs have been known to have several shortcomings: limited source, inconvenient collection, poor proliferative capacity, and difficult in vitro culture.OBJECTIVE: To investigate the proliferation of MSCs after co-culture with NPCs in alginate beads-simulated three-dimensional environment.DESIGN, TIME AND SETTING: A cell observation was performed at the Laboratory of Orthopedics, Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology between December 2007 and October 2008.MATERIALS: Six healthy New Zealand rabbits of 4 months old were provided by the Laboratory Animal Center, Tongji Medical College of Huazhong University of Science and Technology and were used for the present study.METHODS: Rabbit MSCs were isolated and purified using density gradient centrifugation and adherence methods. Rabbit NPCs were isolated and purified using collagenase Ⅱ digestion and adherence methods. Following liposome-mediated green fluorescent protein tranfection and G418 screening, MSCs of passage 3 were cultured either alone (control group) or with NPCs at a ratio of 1:1 (co-culture group) in alginate beads. After 14 days of culture, alginate beads were dissolved and MSCs were collected by flow cytometry sorting.MAIN OUTCOME MEASURES: The expression of collagen Ⅱ and aggrecan in MSCs was detected by RT-PCR and Western blot techniques.RESULTS: mRNA and protein expression of collagen Ⅱ and aggrecan was observed in the co-culture group, but not in the control group, after 14 days of culture.CONCLUSION: MSC differentiation towards nucleus pulposus-like cells can be induced by co-culture with NPCs in a three-dimensional environment.

Objective To study the expression of transcription factor FOXO1 and FOXO3a on peripheral blood mononuclear cells (PBMC) in patients with active or inactive systemic lupus erythematosus (SLE) and investigate the effect of FOXO1 and FOXO3a on the clinical features of SLE. Methods Thirty SLE patients and 10 healthy controls were enrolled. PBMC were separated from the peripheral blood. Reverse transcription-polymerase chain reaction (RT-PCR) and western blot were applied to analyze the expression of FOXOI and FOXO3a. Results The level of FOXO1 expression was significantly decreased in active SLE patients compared with controls and patients with inactive SLE (P<0.05). The level of FOXO1 expression in inactive SLE patients was lower than that of the controls (P<0.05). The expression of FOXO1 mRNA was negatively correlated to SLEDAI. However, the level of FOXO3a was similar among the three groups. Conclusion The result suggests that FOXO1 may be involved in the pathogenesis of SLE and the expression level of FOXOI may be a good indicator for the disease activity of SLE.

Objective To evaluate the effects of tumor-associated macrophages on the proliferation,invasion and migration of human cutaneous malignant melanoma cells.Methods Cultured U937 human monocytic cells at logarithmic phase were classified into three groups to be pretreated with phorbol ester for 48 hours followed by 48-hour activation by phorbol ester (M polarization),lipopolysaccharide (LPS) at 25 mg/L (M1 polarization),and interleukin (IL)-4 at 15 μg/L (M2 polarization) respectively.Then,enzyme-linked immunosorbent assay (ELISA) was performed to determine the levels of IL-12p70 and IL-10 in the supernatant of these activated cells.A375 human malignant melanoma cells were divided into four groups to be cultured alone or with M-,M1-and M2-polarized macrophages respectively.After additional culture for different durations (24,48 and 72 hours),methyl thiazolyl tetrazolium (MTT) assay was conducted to estimate the proliferative activity,and Transwell assay to evaluate the invasion and migration activity,of the A375 cells.Results The proliferation of A375 cells was accelerated by coculture with M-and M2-polarized macrophages,but inhibited by that with M1-polarized macrophages,with significant differences among the four groups in the proliferative activity at 48 and 72 hours (all P ＜ 0.05),but not at 24 hours (P ＞ 0.05).Invasion assay showed that the number of A375 cells that migrated through Transwell chambers was significantly larger in M2 and M groups (147.00 ± 7.92 and 113.22 ± 8.15 respectively),but smaller in the M1 group (56.44 ± 7.55),than in the control group (84.11 ± 6.07,all P ＜ 0.05).Similarly,migration assay revealed a significant increase in the number of A375 cells that migrated through Transwell chambers in the M2 and M(p) groups (198.33 ± 8.22 and 156.00 ± 8.83 respectively),but a significant decrease in the M1 group (97.11 ± 6.75) as compared with the control group (123.89 ± 7.01,all P＜ 0.05).Conclusions The proliferation,invasion and migration of A375 cells can be accelerated by IL-4-activated M2-polarized macrophages,but decelerated by LPS-activated M1-polarized macrophages.Phorbol ester tends to induce monocytic cells to differentiate into M2-polarized macrophages.
