OBJECTIVETo investigate the action mechanisms of the FZD5 gene in prostate cancer bone metastasis and search for some new treatments for this disease.

METHODSWe determined the expression level of the FZD5 gene in prostate cancer PC3 cells and, after transfection of siRNA into the PC3 cells and silence of the FZD5 gene, observed the changes in the migration and proliferation of the cells. We established the model of prostate cancer bone metastasis by tibial injection of prostate cancer cells in the nude mice. Then we injected control siRNA and FZD5-silenced siRNA into the tibia of the mice followed by evaluation of tumor-induced bone destruction by X-ray imaging at 0, 1, and 3 weeks and by HE staining at 3 weeks after injection.

RESULTSAfter transfection of FZD5-silenced siRNA into the prostate cancer PC3 cells, the expression of the FZD5 gene was decreased about 70%. The rate of cell proliferation was significantly lower in the gene silencing group than in the control (P < 0.05), and that of cell migration dropped by 30% in the former as compared with the latter group at 48 hours after FZD5 silencing (P < 0.05). At 3 weeks after injection of control siRNA or FZD5-silenced siRNA into the tibia of the mice, osteolytic damage was observed in both groups, though less in the FZD5 silencing group, with only a few remaining bone trabeculae visible.

CONCLUSIONSilencing the FZD5 gene can reduce the migration and proliferation of prostate cancer cells, help to suppress bone metastasis and destruction, and thereby improve the survival rate and quality of life of the patients.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

The quality and function of the donor liver is one of the main factors which influence the success and prognosis of liver transplantation.At present,the major source of donor liver for transplantation is Donor of Brain Death (DBD) all over the world,which has unstable circulation.When the brain death occurs,a series of serious physiological function changes will be induced within a few minutes and affect the hemodynamics and homeostasis of the body,which will greatly influence the liver quality and function,and consequently the success and prognosis of liver transplantation,finally leading to the loss of potential donor organs.Therefore,it is necessary to identify the physiological function changes induced by the process of brain death and its injury to liver and take immediate proper protective measures,which can effectively reduce the organ injury,improve liver function and enhance the organ utilization and liver transplantation success.In this paper,the changes and maintenance measures of liver physiological function in DBD will be reviewed.

Objective To characterize the association of adiponectin,leptin and free fatty acids(FFA)with adiposity,insulin resistance,lipid profiles and inflammatory markers in type 2 diabetes.Methods We measured fasting serum adiponectin,leptin,FFA,high-sensitive C reactive protein(hs-CRP) levels and metabolic parameters in 77 cases of type 2 diabetic patients with or without obesity and 26 healthy subjects.Results Following parameters were significantly higher in type 2 diabetic patients than in healthy subjects: fasting serum leptin(?g/L)(4.5?3.9 vs 4.1?2.1),hsCRP(mg/L)(0.69?1.07 vs 0.33?0.47),FFA(?mol/L)(566?227 vs 391?129) and triglyceride(mmol/L)(1.61?1.02 vs 1.01?0.40);however,following parameters were significantly lower in type 2 diabetic patients than in healthy subjects: serum adiponectin(mg/L)(5.5?3.4 vs 9.1?4.1),highdensity lipoprotein cholesterol(HDL-C)(mmol/L)(1.22?0.27 vs 1.48?0.26), apolipoprotein AI(mmol/L)(1.35?0.19 vs 1.49?0.18) and apolipoprotein AII(mmol/L)(0.29?0.07 vs 0.34?0.06) concentrations(P

Objective To preliminary screen serum microRNA which was related to class Ⅳ and class Ⅳ+Ⅴ lupus nephritis (LN)by using microRNA array technology,and explore the role of serum microRNA in renal pathological classification of lupus nephritis.Methods Eight serum samples of lupus nephritis patients from biological specimen library in our hospital were enrolled. Experimental group was composed of 4 class Ⅳ cases and 4 class Ⅳ+Ⅴ cases,control group was composed of 4 healthy persons. MicroRNA array was used to screen the differentially expressing microRNA.Results There were part of same miRNA in class Ⅳand classⅣ+Ⅴ LN,among which expression of 22 miRNA were significantly different,29 miRNA of classⅣ was unique,3 miRNA of class Ⅳ+Ⅴ was unique.Conclusion Serum miRNA has a potential to serve as a biomarker to identify class Ⅳ and classⅣ+Ⅴlupus nephritis.

OBJECTIVE:To establish the Evaluation Criteria on Rational Use of Human Serum Albumin(HSA)in our hospi-tal,and to provide refereuce for rational use of HSA. METHODS:Referring to drug utilization evaluation(DUE)criteria of WHO and developed countries,based on the guideline of HSA use,Human Serum Albumin,Non-protein Colloid and Crystalloid Solu-tion Guidelines of USA University Hospital Consortium,Blood Products Prescription Evaluation Guideline of Beijing area,etc., Evaluation Criteria on Rational Use of HAS was established through experts discussion,and the use of HAS in 420 patients of our hospital were evaluated. RESULTS:The Evaluation Criteria on Rational Use of HSA mainly included indication,contraindication, usage and dosage,drug combination,incompatibility,etc. 414 patients (98.57%) detected serum albumin concentration before treatment;167 patients(39.76%)were in line with the indication;56 patients(13.33%)had contraindication in using HSA;352 patients(83.81%)met the criteria in usage and dosage,duration of treatment;there were 17 cases(4.05%)of unreasonable drug combination and 3 cases(0.71%)of incompatibility. CONCLUSIONS:The established criteria has strong practicability,and some problems and insufficiencies can be found in the clinical practice,is conducive to promote rational drug use in the clinic.

Objective To summarize the clinical features,neuroimaging findings and pathological characteristics of demyelinating pseudotumors(DPT)of the brain,and to differentiate it from glioma. Methods The clinical features,neuroimaging findings and pathological characteristics of 35 patients with demyelinating pseudotumors of the brain were summarized,and the diagnosis for 18 of them was confirmed by bioscopy.Results Demyelinating pseudotumors affected adults of both sexes.The onset age of patients ranged from 9 to 69 years old.There was no definite antecedent,and the clinical syndromes were atypical. Neuroimaging scans showed multiple lesions in cerebral hemisphere,while the lesion in brain stem and spinal cord was single.The symptom and neuroimaging were not parallel.While with many or large lesions, the symptoms and signs were less.The lesions were not enhanced on CT scan,but appeared round or patch enhancement on MRI scan.Nine patients with DWI all appeared high density.The myelin basic protein was useful for diagnosis.The typical pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis.The Creutzfeuldt cells were also found in these patients.The lesions might become small or disappear after treatment,but could not serve as the criterion to exclude brain neoplasm. Conclusions DPT is a distinct demyelination disease entity,which is confusable with brain neoplasm.It is difficult to distinguish DPT from brain neoplasm with the clinical features and conventional neuroimaging scan.But DWI scan is useful.The pathological changes accord with demyelination,and Creutzfeuldt cells are also found.It is important to apply corticosteroid treatment or biopsy rather than being anxious to excise the lesions.
