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.

Objective To investigate the relationship between vascular endothelial function and insulin resistance(IR) and the incidence of metabolic syndrome(MS).Methods A seven-year follow-up study was conducted in 583 simple obese subjects who were chosen in 2000.Body fat,blood pressure,lipid profile,plasma glucose,insulin resistance index(HOMA-IR) and endothelium- dependent dilatation(EDD) were measured before and after the follow-up.Results A total of 177 new cases with MS were found during this seven years,which was 33.78% of all subjects who were followed up in 2007.Cumulative incidence of MS among seven-year was 38.14% in the impaired EDD group and 48.11% in the impaired EDD with IR group,both rates were higher than that of the IR group(25.00%)(P

AIM: To study the causes of pyogenic granuloma after hydroxyapatite(HA) orbital implants.METHODS: HA orbital implants (250 cases) in our hospital (68 pegged implants) were reviewed.All patients were followed up from 18 months to 10 years. Implants were removed after medical therapy which was proved to be ineffective.RESULTS: Ten of 250 cases of HA orbital implants developed pyogenic granuloma. Pyogenic granuloma occurred in 1 unpegged implants patient and 9 patients after pegging and drilling of HA implantation over 4～7 years. The pyogenic granulomas were not controlled by medical therapy effectively. Implants were removed in 9 cases except 1 case denied removing and continued medical therapy.CONCLUSION: Pyogenic granuloma was serious complication that occurred after HA orbital implants. Partial vascularization, implant exposure, xenogenic sclera implant, pegging and drilling of HA implantation are risk factors that affect the development of pyogenic granuloma.Pyogenic granuloma hasn't relation with implanted peg material. Pyogenic granuloma denotes the potential implant infection, and all implants should be removed finally.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.

Objective To investigate the association between peripheral white blood cell (WBC) count and the carotid intimal-medial thickness (cIMT) in middle-aged and elderly Chinese of suburban area of Shanghai.Methods A total of 2 519 subjects aged 40 years or older from Jiading District,Shanghai were recruited to undergo questionnaire interview,anthropometric measurements,fasting blood sampling,and carotid B-mode ultrasonography.After excluding subjects with biochemical index missing,WBC count ＞ 10× 109/L as well as those with known myocardial infarction,cerebral infarction,coronary heart disease,and those taking lipid-lowing agents,2 239subjects were included in this analysis.Results Increased WBC count was associated with more unfavorable metabolic risk profiles.With the increasing quartiles of WBC count,cIMT were 0.558,0.570,0.573,and 0.587mm respectively(P for trend ＜ 0.01).As compared with participants in the first WBC quartile,the risks of cIMT thickening were increased by 79％,109％ in males and 29％ in females (P＞ 0.05 in females).Multiple linear regression model showed that peripheral WBC count was an independent risk marker for cIMT thickening,especially for neutrophil and monocyte count.Conclusion A high-normal WBC count was significantly associated with cIMT thickening in middle-aged and elderly Chinese of suburban area of Shanghai,especially in males.

Objective To investigate the function of transferrin-DNA complex,transported by transferrin(Tf)and trans-arterial injection via interventional approach be the duel-target-orientated delivery and the transferring into malignant cells to get more effective therapy.Methods p53-LipofectAMINE ligand with different concentrations of Tf(0,10,25,50,100?g)transfected the 4 strains including LM6、Hep3B、YY and L02 in vitro to evaluate the gene transfeetion efficiency through western blot.Then,after setting up the VX2 hepatocarcinoma models,we delivered the Tf-p53-LipofeetAMINE complex into the hepatic arteries via interventional techniques to analyse the transfection efficiency in vivo.Results Tf,within the range of 10 100?g,could increase gene transfection efficiency mediated by liposome,and the efficiency increases with the raise of Tf concentration.Combination with interventional technique to inject Tf-DNA complex into tumor arteries,gene transfeetion efficiency was enhanced in rabbit models.Conclusion Tf can enhance gene- liposome transfection efficiency,furthermore with combination of interventional catheter technique,there would be a potential duel-target-orientated gene therapy method.(J Intervent Radiol,2007,16:99-103)

Objective To understand the relationship between childhood non-intentional injury and socio-economic status (SES) in Jiangxi province. Methods Nearly 100 000 households were selected by PPS sampling method, in Jiangxi province. All children aged 0-17 years in selected households were surveyed using an 'injury questionnaire'. SES was calculated under the World Bank method. Results 98 335 children were surveyed and the identified number of non- intentional injury cases was 5429 and with 52 fatal cases. The morbidity was 5.52% and mortality was 52.88/100 000. The mortality of children with higher SES was lower than that of other groups but without statistical significance. The morbidity of moderate injury increased with the increasing SES, also without statistical significance. However, the morbidity of severe injury in male children decreased with the increasing SES. Rates of moderate injury morbidities of fall and road traffic injury also increased with the increasing SES. Moderate injury morbidity caused by animals decreased with the increasing SES. Severe injury morbidity of fall decreased with the increasing SES. Conclusion The morbidity of injury in children was affected by the SES and the relationship between injury and SES varied along with the results of different types of injuries.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.
