Capital logic is the first to be avoided in the construction of medical humane service system,for it is capital logic that manifest the current technical and commercialized time with an "indifferent" characteristic.Capital logic originated and distended from the western culture.As another spiritual pursuit and wisdom,traditional Chinese philosophy provides us with significant ideological resources and helpful revelation for improving medical humane service in current circumstances.

AIM: To investigate the sequence expression o f CD158 molecule after tacrolimus (FK506), mycophenolate mofetil (MMF) combined with methylprednisone (MP) treatment for refractory chronic graft-versus-host di seases (cGVHD). METHODS: The efficacy and the side effect were observed in 6 chi ld patients with extensive cGVHD after allogeneic hematopoietic stem cell transp lantation treated with the combination of FK506, MMF and MP, meanwhile the chang es of the CD158 expressions on T lymphocytes and NK cells in peripheral blood be fore and after treatment were observed. RESULTS: The expression of CD4+CD158a+ and CD4+CD158b+ were very low before and after transplantation and treatment, there was no stati stical significance. The expression of CD3+CD158b+ and CD3+CD8+CD158b + were 4.97%?2.36% and 4.58%?2.90% respectively in five patients with acut e GVHD, and there was statistical significance compared with that of before-tran splantation (P

Aim To investigate the time-dependent effect of insulin on the expression of SREBP-1(sterol regulatory element binding protein-1),FAS(fat acid synthase)and lipid droplet formation in HKC cells(human renal proximal tubular epithelial cells line).MethodsHKC cells were respectively treated with 100 nmol·L~(-1) insulin for 0,2,4,6,12 h and 24 h.The analysis of SREBP-1 and FAS mRNA was performed by RT-PCR and the expression of SREBP-1 protein was detected by Western blot and immunocytochemistry.Furthermore,Oil Red O staining was used to determine cellular lipid droplet formation.ResultsCompared with HKC cells of 0 h group,there was no difference of SREBP-1 and FAS mRNA in HKC cells of 2 h group.However,the expression of SREBP-1 and FAS mRNA was significantly increased in HKC cells of 4,6 h and 12 h group.Further,the most expression of SREBP-1 and FAS mRNA was at 6 h group and was respectively increased by 3.578 and 4.272 times compared with 0 h group.The results of Western blot showed that the precursor and mature segments of SREBP-1 protein in 4,6 h and 12 h group HKC cells were increased and those of 6 h group HKC cells were the highest and about 4.106 and 5.167 times than those of 0 h group HKC cells.Immunocytochemistry presented the result that SREBP-1 protein was located in the plasma and the expression of 4,6 h and 12 h group HKC cells was significantly higher than that of 0,2 h and 24 h group HKC cells.The result of Oil Red O staining showed that lipid droplet markedly deposited in 6 h group HKC cells,contrarily,no lipid droplet was found in HKC cells of other groups.ConclusionAbove results suggested that insulin up-regulated SREBP-1 and FAS in time-dependent manner that led to cellular lipid droplet deposit,which may play an important role in the pathogenesis of renal lipid accumulation in metabolism syndrome.

Aim To investigate the effects of suppressor of cytokine signaling-1(SOCS-1)on advanced glycation end products(AGEs)induced-renal tubular epithelial-myofibroblast transdifferentiation and activation of JAK/STAT in cultured human renal tubular epithelial cells(HKC).Methods Stable transfections of HKC with pCR3.1 vector and pCR3.1/SOCS-1 were performed with Lipofectamine 2000,and cells were selected with geneticin.Cells were stimulated with BSA and AGEs. The protein expressions of SOCS-1,α-SMA,E-cadherin,Col I,signal transducer and activatior of transcription 1,3(STAT1,STAT3),p-STAT1 and p-STAT3 were observed by Western blot.The protein synthesis of TGF-β_1 in the supernatants of the HKC was detected by enzyme-linked immunoadsorbent assay(ELISA).α-SMA and E-cadherin mRNA were measured by reverse transcription and polymerase chain reaction(RT-PCR).Results Compared with control group,the expression levels of α-SMA protein and mRNA and Col I were significantly increased in HKC with AGEs stimulation and there was a higher concentrations of TGF-β_1 in the supernatants.However,the expression of E-cadherin protein and mRNA were decreased with AGEs stimulation.Overexpression of SOCS-1 inhibited AGEs-induced activation of STAT1 and STAT3 and high expression of α-SMA protein and mRNA and Col I,and reversed the expression of E-cadherin protein and mRNA induced by AGEs.Meanwhile,overexpression of SOCS-1 reduced the concentration of TGF-β_1 in the supernatants of HKC with AGEs stimulation.Conclusion Overexpression of SOCS-1 inhibits AGEs-induced renal tubular epithelial-myofibroblast transdifferentiation maybe partly through blocking activation of JAK/STAT.

Objective To investigate the protection effect of inferior vena cava filter on pulmonary embolism in patients with deep venous thrombosis(DVT) of lower extremities. Methods Inferior vena cava filters were placed in 55 patients with DVT. Simon Nitiol filter(SNF) was used in 25 cases,Trap Ease filter(TEF) in 13 cases and Antheor Temporal filter(ATF) in 17 cases.10 patients with DVT were treated by non operation therapy,45 patients by operation and transluminal angioplasties.Whether patients occurred pulmonary embolism was observed clinically,and the form and site of SNF and TEF were monitored by periodic fluoroscopy . Results Inferior vena cava filter was placed successfully in all patients.Symptoms and signs of DVT disappeared in all the patients after treatment . None of the putients occurred pulmonary embolism in this series. One case occurred inferior vena cava thrombolism in 16 months after SNF placement. Thrombus attached to ATF after the ATF taking off from inferior vena cava was found in 17 cases.Conclusions Inferior vena cava filter placement is a simple, safe and efficient method to prevent pulmonary embolism in a short period.But its long term complications should be considered and investigated.

Purpose To study the value of contrast-enhanced ultrasound (CEUS) quantitative technique in evaluating the perfusion of hepatic microcirculation in acute hemorrhagic shock (HS),and to investigate the value of CEUS quantitative analysis in HS diagnosis and treatment.Materials and Methods Sixty healthy adult New Zealand white rabbits of either gender were randomly divided into three groups for establishing mild,moderate and severe HS models,respectively.Before modeling and 30 min after stable modeling,liver CEUS examination was performed,and the original images were stored.Blood test of lactic acid,liver function,and liver biopsy for pathological examination were conducted after CEUS.Finally,the arrival time (AT),time to peak (TTP),rising time (RT),peak intensity (PI) and area under the curve (AUC) were analyzed offiine.Results Compared with pre-modeling,AUC decreased in mild HS group (P＜0.05);TTP and RT were delayed,but PI and AUC decreased in moderate and severe HS groups (all P＜0.05);AT was delayed in severe HS group (P＜0.05).The differences of TTP,RT,PI and AUC between the groups of mild,moderate and severe HS were significant (P＜0.05).Compared with pre-modeling,lactic acid in three HS groups increased significantly,the liver function indexes were changed to different degrees,and the degree of liver cell pathological changes was closely related to the degree of HS.Conclusion CEUS can quantitatively evaluate the changes of hepatic microcirculation induced by HS at different degrees.

Objective:To investigate the feasibility of periodontal mechanical therapy for chronic periodontitis and coronary heart disease patients with low dose of aspirin.Methods:Sixty nine chronic periodontitis patients with coronary heart disease were randomly selected as the experimental group (medication group,group A),the control group (withdrawal group,group B) including 20 chronic periodontitis patients with coronary artery disease,stopping the drug for one week and another control group with 50 chronic periodontitis patients (group C).The three groups were examined with pocket probing,and received supragingival scaling,subgingival scaling,and root planning.Local bleeding after operation was observed.In 30 minutes after periodontal mechanical treatment,there was still a need to take some hemostatic measures (containing the oxidized cellulose putting in the periodontal pocket,gauze oppressing,and suturing).Nd:YAG laser was used to stop bleeding 60 minutes after operation.Results:At baseline,there was no significant difference in the three groups,as to the plaque index (PLI),the probing depth (PD),and the attachment loss (AL).The bleeding index (BI)in group A was significantly higher than that in group C (P =0.024),higher than that in group B (P =0.088).The platelet maximum aggregation rate (Aggmax) was detected in some subjects.The average Aggmax value group A was 15.2％,which was much greater than that in group B (60.7％) and group C (62.5 ％).The three groups were all safe in the treatment of periodontal therapy.There were five cases of active bleeding in group A,one case in group B and one case in group C in 30 minutes after operation.In 60 minutes after operation,there was one case of bleeding actively in group A.Nd:YAG laser was used to stop bleeding successfully.Conclusion:The chronic periodontitis and coronary heart disease patients with long-term oral administration of low dose of aspirin can be safely treated with periodontal mechanical treatment,and the effect of local hemostasis is positive without stopping the drug.

Objective To assess temporary filter in the inferior vena cava (IVC) for trapping thrombus and preventing pulmonary embolism in patients with deep vein thrombosis. Methods In 58 cases of deep vein thrombus in single lower extremity, Antheor temporary filter (ATF) was introduced into IVC prior to anticoagulation and/or vascular intraluminal procedures. Results All IVC filters were successfully introduced. No symptomatic pulmonary embolism was documented. ATF was removed after a mean of 12.0?2.0 days. Thrombus was trapped in 46 cases (79.3%). Thrombus more than 1 cm in size was trapped in 2 cases. Conclusion Temporary filter was safe and effective in prevention of pulmonary embolism.

Objective To study methods of salvage therapy for acute lower extremity(ALEI) ischemia.(Methods) A restrospectively analyzsis was made on the clinical data of 96 patients with consecutive 106 ALEI limbs.In which Fogarty catheter embolectomy was used as the initial treatment for ALEI in a regular(operating) room or in an intervention therapy room under DSA monitoring,and graft bypass after embolectomy was performed on 8 cases(12 limbs).Results In 70 cases(75 limbs) successful embolectomy of the(iliac),femoral,popliteal and tibial artery was achieved.In 11 cases(12 limbs) embolectomy at distal to the popliteal artery was unsuccessful.Eight cases(12 limbs) with obstruction proximal to the femoral artery were treated by axillofemoral bypass in 4 cases,and femorofemoral bypass in 4 cases.One case of thoracoabdominal aortic dissection aneurysm and lower extremity ischemia had fenestration of the abdominal aoric dissection.Proximal embolectomy and distal amputation was performed in 6 cases.Fimally,76(79.2%) cases had(salvaged) limbs,11(11.4%) patients had amputated limbs,and 9(9.4%) patients died.Seventy-six(patients)(85 limbs) were followed up for 1 to 38 months,7 cases(7 limbs) were reoperated on because of recurrent embolism.Conclusions Embolectomy is the effective treatment method for ALEI.Embolectomy(under) DSA monitoring can improve therapeutic results.The prognosis lies on the duration and extent of(ischemia),and management of complications.
