Objective To investigate the correlation between serum bone metabolism biomarkers and bone mineral density (BMD) in chronic kidney disease (CKD) patients with different stages. Methods Seventy-eight CKD patients were enrolled in this study and were assigned to different groups according to their ereatinine clearance (Cer). Patients with Cer ≥ 15 ml/min were divided into 4 groups based on clinical CKD 1-4 stage standard, and those with Ccr<15 ml/min were divided into two groups of hemodialysis (HD) and non-HD. Their levels of serum calcium, phosphorus, alkalinity phosphatase (ALP), urea, Ser, osteocalein (gla-protein, OC), calcitonin (CT), intact parathyroid hormone (iPTH), osteoprotegerin (OPG) and BMD were detected respectively. Results (1) The serum levels of OPG, iPTH and phosphorus increased significantly in stage 3, 4, 5, respectively (P<0.01), and serum OPG level was elevated to (5.1±1.34) ng/L after HD, which was significantly higher than (3.35±0.76) ng/L before HD (P<0.05). The levels of serum OC, CT, calcium, ALP were not significantly different among patients with different CKD stages, while the level of OC was elevated in HD patients (P<0.05). The femoral WARDS triangle BMD of CKD stage 4 patients decreased to 0.77±0.09, which was less than the value of CKD stage 1 patients (P<0.01), with litde influence from hemodialysis treatment. (2) The level of serum OPG was positively correlated with the levels of serum phosphorus, iPTH, OC (r = 0.51, 0.39, 0.36,all P<0.01), and it was negatively correlated with the level of Ccr (r =-0.70, P<0.01). The femoral WARDS triangle BMD was negatively correlated with the levels of iPTH, OC, phosphorus and OPG (r =-0.59,-0.51,-0.45,-0.48, all P<0.05). Conclusions Most of serum bone metabolism biomarkers change according to the declined level of Cer. Compared with serum phosphorus, the levels of iPTH, BGP and femoral WARDS triangle BMD, serum OPG may be early diagnosticmarkers of renal osteodystrophy in CKD patients.

Objective To construct F344 rat bone marrow mesenchymal stem cell line (MSC) modified with human hepatocyte growth factor (hHGF) gene.Methods Recombinant virus containing hHGF was obtained by transfecting the packaging cell line 293 FT with lentiviral vector pLV/EF1α-hHGF-IRES-eGFP.MSCs derived from F344 rat bone marrow were then tranfected with packed lentiviral vector.Purified MSCs expressing hHGF was obtained by screening culture with G418.MSCs and MSCs transfected with empty vector were used as control.The expression of hHGF protein was detected by Western blot (eGFP-MSCs).The hHGF-transfected MSCs were cultured in osteoblast-inducing culture medium and osteoblast phenotype was assayed by alizarin Red staining.The cells were also cultured in adipogenesis medium and stained with Oil Red O for identification.Results The expression of hHGF protein was significantly up-regulated in the hHGF-MSCs as compared with MSCs and eGFP-MSCs.hHGF-MSCs readily differentiated into mineralizing cells or adipocytes when incubated in differentiation medium.Conclusion A F344 rat MSC line that stably expresses HGF is successfully established.

Objective To investgate the changes in the expression of hepatocyte growth factor (HGF)and c-met in the lungs in a rat model of pulmonary hypertension.Methods Eighty 7 week old male SD rats weighing 180-250 g were randomly divided into 2 groups ( n =40 each ):control group (group C) and pulmonary hypertension group (group PH).Pulmonary hypertension was induced by left pneumonectomy and subcutaneous monocrotaline (MCT) 60 mg/kg 2 weeks later.Pulmonary artery pressure and the ratio between the weight of right ventricle and left ventricle + interventricular septum ( RV/LV + S) were measured at 7,14,21 and 28 d after MCT administration.HGF and c-met protein and mRNA expression and TGF-β content in the lung tissue were determined.Results Pulmonary hypertension and right ventricular hypertrophy associated with hypertrophy of pulmonary artery tunica media and muscularization of small pulmonary arteries developed after MCT administration in PH group.In PH group HGF protein and mRNA expression in the lungs was significantly down-regulated as compared with group C.There were no significant differences in c-met protein and mRNA expression in the lungs between the 2 groups.The TGF-β content in the lungs was significantly increased in group PH as compared with group C.Conclusion Decrease in HGF production in the lungs plays an important role in the pulmonary hypertension.Increasing of pulmonary TGF-β may play an important role in the down-regulation of pulmonary HGF expression during pulmonary hypertension.

OBJECTIVE: More than 70% of hepatic alveolar echinococcosis (HAE) are inoperable. Thus, long-term, or even life-long, pharmacological treatment with benzimidazoles is necessary. For effective treatment, it is of great importance to employ imaging techniques to detect and monitor the non-resectable parasitic viability. Therefore, this study aimed to evaluate diffusion-weighted imaging (DWI) in assessing the viability of HAE in comparison to 18-fluoro-deoxyglucose (18F-FDG) positron emission tomography, combined with computed tomography (PET/CT). MATERIALS AND METHODS: Positron emission tomography, computed tomography and DWI (b-values: 0, 800 s/mm2) were retrospectively analysed in eight patients with clinically-verified HAE to, generate the apparent diffusion coefficient (ADC) map. The activity of HAE lesions in both techniques were determined independently by two radiologists according to the following standard: (+), marked focally or perilesionally increased FDG uptake/high signal intensity; (−), a hepatic defect without FDG uptake/no high signal intensity. Every lesion's maximum standardized uptake value (SUV(max)) on the PET/CT images and mean ADC values on the parametric ADC maps were measured respectively. Results of PET/CT and DWI were compared on a per-lesion-basis. Pearson's correlation coefficient was assessed for statistical analysis. RESULTS: A total of 14 HAE lesions were detected. Eight lesions (diameter 3–15 cm) showed perilesional hyper-signal intensity on DWI. This was visualised on PET/CT as increased FDG uptake. They mainly existed in the lesion's border with normal liver parenchyma. Five lesions (diameter < 2 cm) were detected as nodular hyperintensity on DWI and a ‘hot spot’ on PET/CT in the same distribution. One patient, who had received oral drug therapy for three years showed significantly decreased perilesional hyperintensity on the DWI and a hepatic defect without any FDG uptake on PET/CT. Pearson's correlation coefficient indicated a significant inverse correlation of the ADC and the SUV(max) (r = −0.67, p < 0.001). CONCLUSION: Diffusion-weighted imaging is capable of offering information on visually detecting the HAE lesions' viability and may be useful for routine application in the initial diagnosis of HAE.

Test of binary logistic regression revealed that age, workage, work posture, handling habits were the factors of OMD (P<0.01) . Conclusion Safety behaviors were the potent factors of OMD that work posture and handling habits should be broadcast.

OBJECTIVE: To determine the effect of ulinastatin on plasma thromboxane B(2) and deep vein thrombosis(DVT) in elderly patients after hip joint replacement. METHODS: Eighty ASAI-IIpatients aged 65-81 years undergoing hip joint replacement were randomly divided into 4 groups (n=20): Group U1 (ulinastatin 5 000 U/kg);Group U2 (ulinastatin 10 000 U/kg); Group U3 (ulinastatin 20 000 U/kg); and Group C (the same volume of saline as control).The blood samples were collected at 5 time points: preoperation (T(1)), immediately after the operation (T(2)), 1 d (T(3)), 2 d (T(4)) and 3 d after the operation (T(5)), respectively. Thromboxane B(2) was detected, and DVT was also examined through color Doppler ultrasonography 3 d after the operation. RESULTS: Compared with T(1), the level of thromboxane B(2) significantly increased in Group C at T(2)-5, in Group U1 at T(2-4), in Group U2 and U3 at T(2) (P<0.01). Compared with Group C, the concentration of thromboxane B(2) decreased in Group U1 at T(2-3), in Group U2 and U3 at T(2-4) (P<0.01). Compared with Group U1, thromboxane B(2) significantly decreased in Group U2 and U3 at T(2-4) (P<0.01).The incidence rate of DVT was 40% in Group C, 10% in Group U1. There was no incidence of DVT in the Group U2 and U3 (P>0.05). CONCLUSION Ulinastatin can inhibit blood thromboxane B(2) level in dose dependent manner and prevent DVT in elderly patients after hip joint replacement.

Cost data caliber governance is key to fine cost management. To tackle the troubles in cost data management at multiple campuses of one hospital, the authors built a multi-campus cost data caliber governance mode. By means of enhanced top-level design, the mode carried out data governance by such measures as the establishment of data dictionary mapping library, standardizing department names and caliber, classification of charging items of medical services, precisely matching between fixed assets and charging items, interconnecting the management system of charging library and the procurement library of consumables, as well as precisely matching surgical disease types and charging items. These measures accomplished the consistency and comparability of cost data across campuses, building an automated, streamlined, standardized and integrated data governance mode for reference of hospitals with multiple campuses in need of cost management.
