Microparticles in the peripheral blood are generated from the activated blood cells and vascular endothelial cells. Microparticles reflect the functional situations of their original cells directly and specifically,provide the basis for revelation of mechanisms and development trends of hematological or vascular diseases and also serve as the indications for differentiation diagnosis and evaluation of clinical treatment. Therefore it is very important to detect microparticles. This article will explain the present detection methods and the correlation of microparticles with diseases to provide basis and strategy for further study.

Objective To investigate the relationship between diagnosis and treatment of the primary peritoneal carcinoma(PPC)and its prognosis.Methods The clinical materials of 10 women,who were diagnosed with PPC,were analyzed retrospectively from Mar.2000 to Nov.2006.Results We found that PPC has lower rate of incidence,higher rate of wrong diagnosis,wider spread in pelvis cavity and abdominal cavity and had no significant clinical signs and symptoms specificity.All of the patients needed cytoreductive surgery,but the majority of rudimental focus diameter is larger than 2 cm.After the operation,platinum combined other chemotherapeutic drug were needed.Conclusion Abdominal distention,ascites,abdominal pain are the main symptoms and signs of PPC.we need choose cytoreductive surgery as much as possible.Extra trauma to patients will affect restoration and survival time of patients and the effect of chemotherapy.We also found the effect of abdominal cavity chemotherapy may be better than that of chemotherapy in vein.

OBJECTIVE: To investigate the self-management behaviors of patients with type 2 diabetes mellitus (DM) in a community and to explore the relationship between self-management behaviors and the glycemic control. METHODS: A total of 211 type 2 DM patients in a community were selected by stratified random sampling. Patients were grouped according to the scores of self-management behaviors. The fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2hPG) and glycated hemoglobin (HbA1C) level were tested. The differences between groups and relationship between self-management behaviors and glycemic control were analyzed. RESULTS: Self-management behaviors of most patients were not effective, and 2hPG and HbA1C were affected by different levels of the self-management behaviors (P<0.05). The self-management behaviors were negatively related to FPG (r=-0.277, P=0.015), 2hPG (r=-0.453, P=0.001), and HbA1C (r=-0.435, P=0.001). Glycemic control of the patients whose course of disease was over 5 years was significantly different due to different self-management behaviors. FPG level of the patients was positively related to alimentary control. The 2hPG level of the patients was positively related to alimentary control, medication persistence, and blood glucose self-monitoring. The HbA1C level of the patients was positively related to alimentary control and medication persistence. The times the patients received DM education, the way to use insulin, and the disease course of the patients were important factors to affect self-management behaviors of type 2 DM in the community. CONCLUSION Self-management behaviors of type 2 DM patients in the community are not effective. Satisfactory self-management behaviors, specially the control of 2hPG and HbA1C are beneficial to glycemic control. We can improve the self-management behaviors in type 2 DM patients by paying attention to the disease course, the treatment method, and the contents and effect of DM education.

Objective To investigate the characteristic and clinical significance of airway inflammation in children with acute asth-ma. Methods Underwent sputum induction and sputum induction in children (n=34) with acute asthma was repented in recovered children ( n = 24).Induced sputum were also taken from 15 healthy children as controls.Total and differential cell counts were per-formed. Interleukin(IL)-8、IL-6 were measured,The relationship between inflammatory cells and IL-8、 IL-6、peak expiratory (PEF) were analyzed.Results The inflammatory cell infiltrate was mixed including eosmophilic granulocytes, neutrophils, and macrophages. They decreased significantly, but eosinophilic granulocyte remained a higher percentage compared with healthy subjects. There was low-er percentage of lymphocytes at acute exacerhation.Eosinophilic granulocytes were correlated with the degree of airflow obstruction. Levels of IL-8、IL-6 were elevated during the acute exacerbation and decreased at resolution.IL-8 was correlated significantly with neutrophils at acute exacerhation and resolution.IL-6 was correlated signifficantly with eosinophilic granulocytes at acute exacerbation. Conclusions Airway inflammation is chataeterized by infiltration of eosinophils, neutrophils and macrophages.IL-8、IL-6 possibly is the important cytokines of airway inflammation in children with acute asthma. Increased eosinophils in induced sputum correlates with asthma severity. Therapy to the cytokines may have potential values.J Appl Clin pediatr,2004,19(12): 1023-1025

Aim To investigate the role of TGF-β3 in the anti-proliferation effect of ursolic acid(UA)in co-lon cancer cells and the possible molecular mechanism underlying this effect.Methods We introduced crys-tal violet staining,flow cytometry and Western blot as-say to determine the effect of UA on proliferation and apoptosis in HCT1 1 6 cells.The levels of TGF-β3, Smad2 /3 and β-catenin in HCT1 1 6 cell were evaluated by RT-PCR and Western blot.Finally,TGF-β3 inhibi-tor and recombinant adenovirus,and luciferase reporter assay were used to analyze the possible mechanism through which TGF-β3 mediated the anti-cancer effect of UA in HCT1 1 6 cells.Results UA inhibited the proliferation and induced apoptosis apparently in HCT1 1 6 cells.UA down-regulated TGF-β3 both in mRNA and in protein level.Meanwhile,UA decreased the phosphorylation of Smad2 /3 concentration depend-ently,although no significant effect was found on the total protein level of Smad2 /3 in HCT1 1 6 cells.Over-expression of TGF-β3 attenuated the inhibitory effect of UA on the proliferation of HCT1 1 6 cells,while the TGF-β3 inhibitor potentiated this effect. UA sup-pressed the transconduction of Wnt/β-catenin signaling in HCT1 1 6 cells through decreasing the level of β-catenin.Exogenous expression of TGF-β3 increased the level of β-catenin and partly reversed the UA-in-duced decrease of β-catenin.However,TGF-β3 inhib-itor potentiated the inhibitory effect of UA on β-catenin in HCT1 1 6 cells.Conclusion The anti-proliferation activity of UA in colon cancer may be partly mediated through down-regulating TGF-β3 to suppress Wnt/β-catenin signaling at least.

Objective To investigate the effect of low salt diet on vascular remodeling of rat induced by high fructose(HF).Methods Wistar male rats weighed 180-200 g were fed for 8 weeks and randomly divided into 6 groups:(1) control group was given the normal fodder and distilled water;(2) high fructose group(HF) was given normal fodder (0.5 ％ NaCl,w/w) and fructose water(10 ％,w/v);(3) high-salt group (HNa) was given high salt fodder (7 ％ NaCl,w/w) and distilled water;(4) high fructose combined with high salt diet group(HFNa) was simultaneously given high salt fodder and 10 ％ fructose water;(5)high fructose combined low salt group(HFLNa) was simultaneously given low salt fodder and 10％ fructose water;(6) high fructose combined with spirotaclone group(HFE) was given 10％ fructose water for 4 weeks and then added with spirotaelone(50 mg · kg-1 · d-1 by tube feeding) for continuous 4 weeks.The changes of arterial blood pressure,vascular wall histological evaluation and expression of α-SMA and fibronectin in vascular wall were detected in each group.Results (1) Compared with the blood pressure[(111.03 ±9.17) mm Hg] in the control group,the blood pressure in the HF and HNa groups were (133.94± 5.86) mm Hg and (128.09±7.56) mm Hg respectively,which were significantly increased(P＜0.05);(2) HF mainly caused the hyperplasia of vascular wall middle layer smooth muscle.The a-SMA expression results in the HF group was (0.006 3 ±0.000 21),which in the control group was (0.004 6 ± 0.000 31),the difference was statistically significant(P＜0.05),moreover which promoted the elastic fibers increase;while HNa mainly stimulated the elastic fibers to thicken and extracellular matrix deposition,the fibronectin expression was 0.002 6 ± 0.000 2 in the HNa group and (0.004 7±0.000 2)in the HF group,compared with(0.001 3±0.000 1)in the normal group,which were significantly increased(P＜0.001);(3) the blood pressure was (106.04±9.59) mm Hg in the HFLNa group,(103.99±7.12) mm Hg in the HFE group,compared with(133.94±5.86) mm Hg in the HF group,showing that the blood pressure in the HFLNa group and HFE group was significantly decreased compared with the HF group (P＜0.05);moreover the vascular remodeling in the HFLNa group(0.006 8±0.000 2) and HFE group (0.004 2±0.000 4) was improved,and compared with the HF group(0.006 3±0.000 2),α-SMA expression was significantly decreased (P＜0.05).Conclusion Low salt diet can effectively improve vascular remodeling induced by HEF.

Objective:To explore the short-term outcomes of reconstruction of tumorous critical bone defects at femoral shaft with a 3D printed ultra-short stem with a porous structure.Methods:From September 2016 to June 2018, 8 patients underwent reconstruction of critical bone defects with a 3D printed ultra-short stem with a porous structure after resection of femoral shaft malignant tumor at Department of Orthopaedics, West China Hospital. There were 4 males and 4 females, with an average age of 36.9 years (from 11 to 61 years). Their preoperative Enneking staging was stage Ⅱb in all. There were 3 osteosarcomas, 2 Ewing sarcomas, 2 chondrosarcomas and one periosteal osteosarcoma. Preoperative CT/MRI image fusion technology was used to define the surgical boundary, design the guide plate and prosthesis, and perform surgical simulation. Tomosynthesis-shimadzu Metal Artefact Reduction technology was used to evaluate osseointegration. Complications and bone oncology prognosis of the patients were documented. The lower limb function of the patients was evaluated using Musculoskeletal Tumor Society (MSTS) 1993 scoring and knee range of motion.Results:The overall follow-up time ranged from 36 to 50 months, averaging 42.8 months. During operation one patient sustained a periprosthesis fracture, the union of which was followed up after wire assisted fixation. There was no local tumor recurrence, lung metastasis or death. The last follow-up revealed good osseointegration and basically isometric lower extremities in all cases. There was no such a complication as aseptic loosening of the prosthesis, deep infection or prosthesis fracture during the follow-up period. At the last follow-up in the 8 patients, the flexion range of the knee joint was 116.2°±9.1°, significantly improved compared with that before operation (98.8°±10.9°), and the MSTS score was (26.2±2.1) points, also significantly improved compared with that before operation [(21.6±1.8) points] ( P<0.05). Conclusions:Reconstruction with a 3D printed ultra-short stem with a porous structure is an accurate operation for femoral shaft tumorous bone defects. With careful preoperative design, intraoperative manipulation and strict postoperative follow-up management, this operation can lead to fine early curative outcomes for long shaft critical bone defects.
