Objective To investigate the application of computed radiography(CR) in X-ray projection of whole lower limbs.Methods The radiography in the patient with bilateral knee-malformation was performed using 500 mA X-ray apparatus and several imaging plates(IP) jointed together,then the images including whole both sides of lower limbs were obtained by post-proccesing technique.Results The images not only could show the whole lower limbs on a single film,but be intact.The images also could be used for measuring the length of leg,the angle between the axises of the thigh and the magnifying really.Conclusion The image of whole bilateral lower limbs with a good quality and unity can be acquired using CR and post-processing technique appropriately.

To explore the kinetics of LBP/CD14 system in patients with hemodialysis, and further to analyse its role in (he development of systemic inflammation response based on the changes of plasma endotaxin, TNF and IL-6 levels in patients with uremia treated with hemodilysis. Methods Sixteen patients with end-stage renal failure (8 cases with hemodialysis, 8 cses without hemodialysis) were selected for this study. limulus amebocyte lysate chromogenic assay, ELISA and cell in situ hybridization were used to determine the changes in endotoxin, LBP, TNF and IL-6 levels in plasma, and expression of CD14 mRNA in the monocytes. Results (l)Plasma LBP levels in patients with hemodialysis were significantly higher than those in patients without hemodialysis. The expression of CD14 mRNA in the monocytes in patients with hemodialysis was also more obvious. Both of them incresed much more in hemodialysis. (2)Plasma endotoxin levels in patients with hemodialysis, though being significantly higher than in patients without hemodialysis, were in low-level (61.7 ? 10.6 pg/ml). (3) Plasma TNF and IL-6 levels were markedly increased in patients with hemodialysis, which were significantly correlated with plasma LBP levels. Conclusion LBP/CD14 system in patients with hemodialysis is markedly up-regulated, which might be the important mechanism for low-level endotoxemia to exert its effects in hemodialysis.

Objective To explore the multiple pelvic fractures projection methods and value. Methods 50 cases of pelvic trauma patients were divided into two groups for control photography, and underwent X-ray examination with different projection angles.

Objective To explore the role of delivering programmed death (PD)-1 negative costimulation pathways in the prevention of murine BXSB lupus. Methods A recombinant adenovims containing the full-length mouse PD-L1 gene (AdPD-L1) was constructed and was introduced to the BXSB mice. The effect of immunoinhibitory receptor PD-1 on activated lymphocytes was investigated to evaluate its effect on prevention of lupus nephritis in BXSB mice. Results This intervention dramatically delayed the onset of proteinuria, effectively inhibited IgG autoantibody production, and significantly reduced hypercellularity and deposition of IgG in glomeruli, resulting in almost complete amelioration of lupus nephritis in these animals.Conclusion Our results suggest that simultaneous stimulation of PD-1-mediated pathway can potentially revent human lupus nephritis.

AIM: To investigate the role of nuclear factor- κB (NF- κB) in the expression of monocyte chemoatractant protein- 1 (MCP- 1) in human mesangial cells (HMCs) induced by oxidized low- density lipoprotein (Ox- LDL).METHODS: HMCs were used as target cells. Inhibitory κBα (IκBα) and MCP- 1 protein level was measured by cell ELISA.Activities of transcriptional factors NF- κB were determined by electrophoresis mobility shift assay (EMSA). Immunohistochemistry was used to detect the translocation of Rel p65. RESULTS: NF - κB DNA - binding activation in MCs was observed when 10-100 mg/L Ox - LDL was added to the medium, and 50 mg/L Ox - LDL caused the strongest effect (8.50 ± 1.14, P ＜ 0.01vs control; P ＜ 0.05 vs 10, 25 and 100 mg/L Ox - LDL). The most optimal stimulation time was 60 min ( 11.0 ± 2.11, P ＜0.01 vs control; P ＜ 0.05 vs 30 min or 240 min). IκBα protein level in MC dropped down most obviously after 60 min incubation with 50 mg/L Ox - LDL (0.050 ± 0.006, n = 5, P ＜ 0.01 vs control), while MCP- 1 expression level was the highest (0.331± 0.016, n = 5, P ＜ 0.01 vs control). The translocation of Rel p65 from cytoplasm to nucleus was detected too. NF - κB inhibitor pyrroledithiocarbomate (PDTC) could inhibit these effects induced by Ox- DL. CONCLUSION: Activation of NF- κB regulate the expression of MCP- 1 in HMCs induced by Ox - LDL.

AIM:To investigate the protective effect of bactericidal/permeability-increasing protein (BPI) on sepsis induced by intra-abdominal infection in rats and its mechanism.METHODS:Intra-abdominal infection induced sepsis was reproduced by cecal ligation and puncture (CLP). BPI or equal volume of physiological saline was intra-abdominally given immediately after CLP and 12 hours after CLP respectively (2.5 mg/kg of BPI each time). Plasma endotoxin levels were determined with limulus amebocyte chromogenic assay.RESULTS:(1)The survival time in BPI group was significantly higher than in physiological saline (PS) group. (2)The values of MAP, LVSP, IP, d p /d t max and -d p /d t max in BPI group, although decreasing ,were markedly higher than those in PS group. (3) Plasma glutamate-pyruvate transaminase and urea nitrogen levels in BPI group, though increasing, were significantly lower than those in PS group.(4) There was no significant change of plasma endotoxin levels in BPI group, while plasma endotoxin levels were markedly increased in PS group. There was significantly different between two groups. CONCLUSIONS:BPI has an obvious protective effect on intra-abdominal infection induced sepsis, which might be related to its antagonism against endotoxin.

ObjectiveTo investigate the effects and molecular mechanism of endoplasmic reticalam stress (ERS) on albumin-induced apoptosis in renal proximal tubular cells (HKCs). MethodsWestern blot was performed to detect the relationship of the expression of glucose-regulated protein 78 (GRF78) and CCAAT/enhancer-binding protein-homologous protein (CHOP) with the action time and concentration of haman serum albumin (HSA). Expression levels of CHPO mRNA and protein in HKCs after CHOP siRNA transfection were examined by real-time fluorescence quantitative PCR and Western blot respectively. Annexin-V-FITC and PI doable staining cytometry was used to detect the apoptosis of HKCs induced by HSA and influenced by CHOP siRNA. Results(1)After HKCs were stimulatde by 0, 5, 10, 20 g/L albumin for 24 hours respectively, the expression of GRP78, CHOP and HKCs apoptosis were increased with the albumin concentration (P<0.01). After HKCs were stimulated by 20 g/L albumin for 0, 6, 12, 24, 36 hours respectively, the expression of GRP78 was up-regulated at 6-hour, while CHOP and HKCs apoptosis were increased at 12-hour, and significant differences were found among groups (P<0.01). (2) CHOP siRNA significantly inhibited albumin-induced HKC CHOP mRNA and protein expression, as well as HKC apoptosis (P<0.01). ConclusionsRenal tubular cells exposed to high protein load result in EBS. ERS may subsequently lead to tubular damage by activation of pro-apoptosis factor CHOP.

Objective To evaluate the safety of interventional radiotherapy with X-ray angiography.

Objective To investigate the efficacy and safety of Tripterygium wilfordii Hook F (TwHF) combined with renin-angiotensin system (RAS) blockers in chronic kidney disease (CKD) stages 2~3 of IgA nephropathy. Methods 109 patients were randomized into the observation group and the control group. On the basis of taking RAS blockers, patients in the observation group received TwHF, and patients in the control group received methylprednisolone. The proteinuria, renal function and adverse effect were observed during treatment. Results At 3, 6, 9 and 12 months of treatment, proteinuria in the two groups was lower than the baseline(P <0.05). During follow-ups, there was no significant difference of eGFR between the two groups and baseline (P >0.05). Besides, there was no significant difference in terms of proteinuria, eGFR and effective rate in the two groups. The occurrence rate of adverse effects was 9.8% vs 27.4% and there was significant difference in the two groups (P < 0.05). Conclusions TwHF combined with RAS blockers can decrease proteinuria, protect renal function and have less adverse effects, and it is a useful therapeutic options for CKD stages 2 ~ 3 of IgAN.

Objective To conduct a prospective,randomly controlled trial,evaluating the combination of tacrolimus,corticosteroids and entecavir for the treatment of adult patients with biopsyproven hepatitis B virus-associated membrane nephropathy (HBV-MN).Methods A total of 38 patients with biopsy-confirmed HBV-MN were randomized to the tacrolimus group (n=19) and the control group (n=19).Patients in tacrolimus group received combination therapy of tacrolimus (0.05 mg·kg-1 · d-1),corticosteroids (prednisone acetate,0.5 mg· kg-1 · d-1) and entecavir (0.5 mg/d),whereas patients in control group received entecavir mono-therapy (0.5 mg/d).The primary end point was the percentage of patients reaching complete remission (CR) or partial remission (PR).Results The probability of remission in the treatment group was 88.89％ and 94.44％ after 6 and 12 months,but only 38.89％ and 58.82％ in the control group,respectively.The decrease in proteinuria was significantly greater in the treatment group.Entecavir was used for the treatment of hepatitis in all patients,which caused the disappearance of serum hepatitis B viral DNA(HBV-DNA) and the normalization of ALT and AST levels in 3 months.Notably,two patients in the control group and one patient in the treatment group reached the secondary end point.One patient in the tacrolimus-treated group showed a relapse during the taper period.Conclusion This treatment protocol not only can control the replication of HBV-DNA but also can reduce proteinuria and preserve renal function,it is one of useful therapeutic options for patients with HBV-MN.
