Actin cytoskeleton in podocyte is a complicated network structure,and the stability of this structure depend on many proteins which located in slit diaphragm,the apical membrane domain and the basal membrane domain with the stimulus of mechanical stress,the actin cytoskeleton can be adaptive regulated to maintain the normal function of glomerulus,and several signal pathways involve in the process,such as RhoA/Rho kinase signal pathway and TRPC6.

As the basis of the health management of the elderly, weight management should receive attention from medical practitioners.However, there is an ongoing debate on the ideal range of body mass index for elderly in China.This article aimed to find the suitable body mass index for Chinese old people by reviewing the literature regarding the body mass and obesity of the elderly.Lots of evidence show that overweight and mild obesity appear to be the optimal weight status for the elderly.

OBJECTIVE Ginsenoside metabolite compound K (CK) is a degradation product of ginsenoside in the intestine by bacteria. The anti-inflammatory and immunomodulatory activities of CK have been reported. This study investigated whether CK exerted its immunoregulatory effect through modulation of dendritic cells (DCs) function. METHODS In vivo, severity of collegen-induced arthritis (CIA), T cells and DCs subsets, phenotype of DC were assayed by flow cytometry, CCL19 and CCL21 level in lymph nodes assayed by ELISA. In vitro, bone marrow-derived DCs from normal mice were matured with lipopolysaccharide and treated with CK for 48 h. In vivo, bone marrow-derived DCs were generated from CIA mice before and 2 weeks into CK treatment. DCs were analyzed for migration, phenotype and T- cell stimulatory capacity. RESULTS CK alleviated the severity of CIA, decreased pDCs and mo-DCs, increased na?ve T cells in CIA mice lymph nodes, and suppressed CCL21 expression in lymph nodes. CK suppressed DCs migration induced by CCL21 and T cells-stimulatory capability of DC, down-regulated LPS-induced expression of CD80, CD86, MHCII and CCR7 on DCs. CONCLUSION This study elucidated the novel immunomodulatory property of CK via impairing function of DCs in priming T cells activation. These results provide an interesting novel insight into the potential mechanism by which CK contribute to the restoration of immunoregulation in autoimmune conditions.

To investigate the application of a recently developed metallic oxide semiconductor field effect transistor(MOSFET)detector for use in vivo desimetry.Methods The MOSFET detector was calibrated for X-ray beams of 8 MV and 15 MV,as well as electron beams with energy of 6,8,12 and 18 MeV.The dose linearity of the MOSFET detector was investigated for the doses ranging from 0 up to 50 Gy using 8 MV X-ray beams.Angular effect was evaluated as well in a cylindrical PMMA phantom by changing the beam entrance angle every 15?clockwise.The MOSFET detector was then used for a breast cancer patient in vivo dose measurement, after the treatment plan was verified in a water phantom using a NE-2571 ion chamber,in vivo measurements were performed in the first and last treatment,and once per week during the whole treatment.The measured doses were then compared with planning dose to evaluate the accuracy of each treatment.Results The MOSFET detector represented a good energy response for X-ray beams of 8 MV and 15 MV,and for electron beams with energy of 6 MeV up to 18 MeV.With the 6 V bias,Dose linearity error of the MOSFET detector was within 3.0% up to approximately 50 Gy,which can be significantly reduced to 1% when the detector was calibrated before and after each measdurement.The MOSFET response varied within 1.5% for angles firm 270?to 90?.However,maximum error of 10.0% was recorded comparing MOSFET response between forward and backward direction.In vivo mea surement for a breast cancer patient using 3DCRT showed that,the average dose.deviation between measurement and calculation was 2.8%,and the maximum error was less then 5.0%.Conclusions The new MOSFET detector,with its advantages of being in size,easy use,good energy response and dose linearity,can be used for in vivo dose measurement.

Objective To investigate epidemiological and clinical features of patients with acute brucellosis.Methods The epidemiological,clinical,laboratory and treatment data of patients diagnosed as acute brucellosis during 2002 to 2004 in our hospital were retrospectively analyzed. Results Fifty-one patients had a history of close contact with sheep or cows with brucellsis.Twenty- seven patients had drunk milk or eaten instant boiled mutton.The transmission routes were unknown in 8 patients.All the patients had fever and most had low-grade fever.Fifty-five patients had irregu- lar fever and 20 patients had intermittent fever.The most common manifestations were fever(86/86), fatigue(63/86),sweating(43/86),arthralgia(68/86),orchiditis(7/86),hepatomegaly(8/86),sple- nomegaly(7/86)and headache(18/86).Forty-seven patients had liver dysfunction and 17 patients had thrombocytopenia.Eighty patients recovered and 6 patients relapsed after combination therapy with rifampicin,sulfamethoxazole and quinolone.Conclusion The changes in epidemiological and clinical features of patients with acute brucellosis should be noticed.

AIM: To investigate whether there was nicotinic acetylcholine receptor subunit α 7 (nAChR α 7 ), choline acetyltransferase(ChAT), acetylcholinesterase(AChE) expression and its regulation in mature dendritic cells (DCs). METHODS: Bone marrow(BM) -derived DCs from healthy BALB/c mice were incubated with rmGM -CSF and rmIL-4, and stimulated to mature with LPS. Meanwhile, light microscope and flow cytometry were used to identify DCs, as well as immunocytochemistry, immunofluorescence, flow cytometry and RT - PCR methods were used to dectect expression of nAChR α 7, ChAT and AChE. Flow cytometry was also used to analyze nAChR α 7 expression with mecamylamine (MEC) in 12 h. RESULTS: Both protein and mRNA expression of cholinergic system nAChR α 7, ChAT and AChE were found in mature DCs. Furthermore, nAChR α 7 distributed principally in cell membrane, while ChAT and AChE in cytoplasm. Protein expression of AChE was stronger as compared with ChAT ( P ＜ 0. 05), and there was a trend toward increasing as compared with nAChR α 7. And then, the expression of nAChR α 7 was down regulated by MEC as compared with the group without MEC stimulation(P ＜ 0. 05 ). CONCLUSION: An innate cholinergic system was in mature DCs, which was affected by extrinsic factor ( i. e. , MEC). And it may be involved in anti - inflammation immune adjustion of cholinergic closed - circuit.

Objective To investigate the diagnostic value of echocardiography in arrhythmogenic right ventricular cardiomyopathy (ARVC) by summarizing and comparing the electrophysiological and the imaging features.Methods The echocardiography and MRI were performed in the 65 cases of ARVC to measure the right ventricle and the free wall,noted as TTE-RV,MRI-RV and TTE-RVFW.The velocity of tricuspid valve regurgitation (TRmax) and left ventricular ejection fraction (LVEF) were measured.The three-dimensional electric anatomical model of right ventricular was get by the Carto system,and the right ventricular area (Area-RV),the scar area (Area-Scar) was calculated.Results Twenty-seven cases (41.5 ％) was confirmed by the echocardiography,21 cases (32.3 ％) was suspiciously diagnosed,14 cases (32.3％) was miss diagnosed,and 3 cases (4.6％) was misdiagnosed.Statistically significant difference could be detected among the echocardiography confirmed groups and the other two groups for the parameters TTE-RV,MRI-RV,Area-RV,Area-Scar,and TTE-RVFW (P ＜ 0.05).Also there was a statistically significant difference of the parameters of Area-RV and Area-Scar between the suspiciously and miss diagnosed groups (P ＜0.05).Different echocardiographic findings was found in ARVC with different stages,but myocardial fibrosis and low voltage scar could be detected in all patients on the MRI imaging and and electrophysiological mapping.Conclusions The diagnosis of typical ARVC can be confirmed by echocardiography,but for the patients with early and middle stages,comprehensive evaluation should be refered to the clinical data.
