Objective To analyze the clinical characters of the different degrees nonalcoholic fatty liver (NAFLD) and the relationships with blood uric acid.Methods Two hundred and eighty-two cases body examinational and hospitalized patients were selected.According to whether complicated with NAFLD and liver steatosis degree,patients were divided into 4 Groups.Group A was control group that without NAFLD,Group B was mild NAFLD group,Group C was moderate NAFLD group and Group D was severe NAFLD group.Clinical data,blood lipids,blood uric acid and other biochemical indicators of four groups were compared.Results In 282 cases of patients,there were 78 cases (27.66％) without NAFLD patients,94 cases (33.33％) mild NAFLD,92 cases (32.62％) moderate NAFLD and 18 cases (6.38％) severe NAFLD.As the severity of fatty liver increased,body mass index (BMI) higher and higher ((24.51 ± 2.55),(27.06± 2.81),(28.37± 3.23),(30.71 ± 2.96) kg/m2),and the differences among four groups were statistically significant (F =35.976,P ＜0.05).Gglycerin trilaurate (TG),low density lipoprotein cholesterol (LDL-C) of D group were hihger than other groups ((3.04± 1.22) mmol/L vs.(1.73± 1.46),(2.59 ± 1.78),(2.81 ± 1.94) mmol/L,(2.99± 0.52) mmol/L vs.(2.28±0.78),(2.47±0.75),(2.41±0.74) mmol/L),high density lipoprotein cholesterol (HDL-C) was lower compared with group A,B,C (1.00± 0.23) mmol/L vs.(1.15± 0.24),(1.05± 0.21),(1.00 ±0.21) mmol/L),the differences were statistically significant(F=6.818,4.597,6.414;P＜0.05).In 4 groups the blood uric acid(UA) of groups B,C,D was higher than group A,group D was higher than group B,C,and the differences were statistically significant((316.13±71.86),(356.98±83.00),(355.37±81.01),(409.67 ±50.90) μmol/L;F=8.797;P＜0.05).Conclnsion Obese patients are more susceptible to NAFLD,and NAFLD with a certain degree of lipid and uric acid metabolism,and the severity of NAFLD has a positive correlations with lipids and serum uric acid levels.It is particularly obvious in patients with severe NAFLD,which prompting that blood uric acid level can be used as an independent risk factor in the pathogenesis of NAFLD,and as an auxiliary judge for NAFLD severity index.

ObjectiveTo investigate the effort of MHA-bBMP implantation combined with limited contacted titanium net duct fixation on femoral shaft bone defect of rabbit.Methods48 rabbits were divided into the experimental group (treated with bionic bone MHA-bBMP plus titanium net duck) and control group (treated with iliac autograft plus titanium net duct) with 24 animals in each group. The rabbit femoral shaft bone defect model was established by cutting 10 mm bone fragment off. After operation, bionic bone MHA-bBMP/iliac autograft was implanted into bone defect area and fixed with limited contacted titanium net duck. The general condition, serum alkaline phosphatase, X-ray, histopathologic examination and electron microscope were performed.ResultsThe fixation stability of titanium net duck in two groups was good. The bone defect of two groups was repaired. The results of phosphatase, X-ray, histopathologic examination and electron microscope of two groups were not significantly different.ConclusionBionic bone MHA-bBMP is a high bioactivity substitute, and can obtain therapeutic effect equal to iliac autograft when repairing rabbit's femoral shaft defect.

The marrow stromal cells of adult New Zealand rabbits cultivated and induced in vitro were used to form MCCAB by mixing,seeding and solidifying methods with the aid of alginate. The MCCABs were auto-transplanted intramuscularly into the rabbits for 4 to 8 weeks. The alginate-cancellous bone matrix composites or the cancellous bone matrix alone were implanted as control. The effectiveness of bone formation was assessed by means of roentgenography and histology.The results showed that the osteogeneses of MCCABs were better than those of the alginate-cancellous bone matrix composites and of the cancellous bone matrix. In the MCCABs, both intramembranous and cartilaginous osteogenesis were seen with the former predominating. In the control, only slight cartilaginous osteogenesis was seen. The results suggested that the osteogenesis of the MCCABs constructed by using tissue engineering method was obvious when transplanted intramuscularly, therefore, this kind of tissue-engineered bone could be an effective way for clinical application.

Purpose:To study the effect of amifostine on ef ficacy in patients with advanced non-small-cell lung cancer(NSCLC) treated w ith chemotherapy and the protection of amifostine on myelosuppression induced by chemotherapy and to investigate major adverse reaction induced by amfostine. Methods:33 patients with advanced NSCLC were randomly divided i nto protection group (amosfostine + MMC +VDS + DDP) and control group (MMC + VDS + DDP), The regimen was given every 4 weeks , All enrolled patients were evalua ted for efficacy and hematologic toxicity after 3 cycles of treatment , Patients in both groups were well-matched for baseline disease characteristics. Results:In protection group (PG) , the response rate was 40% (1 CR , 5 PR , 6 NC , 3 PD), whereas in control group (CG) , the response rate was 33.3% (0 CR , 5 CR , 8 NC , 2 PD), the differentce of response rates betwee n two the groups was not statistically significant (P=0.705). The minimum wh ite blood cell (WBC) counts after chemotherapy in treatment group and in control group were (3.387?1.169)?109/L and (2.46?0.98)?109/L respectively (P =0.026). The minimum blood platelet cell (BPC) counts in PG and in CG were (11 4.53?48.24)?109 /L and (88.2?32.83)?109 /L respectively (P=0.091) . The minimum hemoglobin (HB) counts in CG and in CG were (94.4?14.69)g/L and (89 .33?13.98)g/L respectively (P=0.341).

Major ad verse effects of amifostine were mild hypotension , nausea and vomiting , dizzin ess , malaise etc. Conclusions:Amifostine does not reduce the efficacy of chemothe rapy in patients with advanced NSCLC , it can reduce the hematologic toxicity as sociated with chemotherapy of MVP regimen , the adverse effects of amifostine ar e mild.

BACKGROUND:Osteoperiosteal decortication can treat the bone nonunion effectively, promote healing of fracture, but its action principle and key operation are not very clear, and there is less research addressing the postoperative treatment. OBJECTIVE:To review research progress of osteoperiosteal decortication for treating nonunion. METHODS: China National Knowledge Infrastructure, Wanfang database and PubMed database were used to search the related articles. The retrieval key words were “osteoperiosteal decortication, stripping, bone nonunion, bone disunion, bone delayed union”. Osteoperiosteal decortications combined with other fixation methods to repair the healing of bone nonunion were compared and analyzed. Bone implantation and implant management were summarized during repair. RESULTS AND CONCLUTION:105 literatures were retrieved by computer. After primarily screening by reading titles and abstract, irrelevant and repeated literatures were excluded. Finaly, 45 articles were summarized. Action principle, indications and operating points of osteoperiosteal decortications for bone nonunion were summarized. Osteoperiosteal decortications combined with other different fixation methods for the healing of bone nonunion were compared so as to better serve the clinic. Simultaneously, the paper also explores the combination with bone implant and management of implant during repair. Osteoperiosteal decortication with its simplicity and effectiveness has been respected in the field of orthopedics. However, for special patients, such as patients combined with destructive bone disease, osteoporosis, nonunion of hand and foot short bones, the treatment with osteoperiosteal decortications needs further researches.

Objective To introduce the donor heart preservation techniques and study the clini- cal results in 26 patients undergoing orthotopic heart transplantations with long donor ischemia time (DIT) in our center.Methods From Sept.2004 to Aug.2006,26 patients underwent orthotopic heart transplantation at our center with DIT longer than 360 min.Crystalloid cardioplegia was infused through aortic root after aorta was cross clamped.UW solution was used when donor heart was removed.All patients underwent bicaval anastomotic cardiac transplantation.NO was inhaled through ventilator during and after operation in patients with pulmonary hypertension.Results DIT was 360- 560 (mean 401?43) min.There was no operative death in this group.Echocardiography and X-ray examinations in one month were normal.One case of abnormal coronary orifice was subjected to re- anastomosis of aorta.One case of renal failure post-operation was subjected to blood dialysis.Conclu- sion With proper donor heart procurement and preservation,recipient selection,anastomotic technique,efficient postoperative surveillance and pulmonary hypertension treatment,transplanted patients with long DIT can obtain the satisfactory short-term outcome.

Radiofrequency ablation therapy not only causes the necrosis of localized tumor cells,but also produces immunogenic tumor associated antigens and a large number of inflammatory cytokines and a variety of immunogenic mediums,which promotes the local infiltration and activation of immune cells and stimulates the immune system to produce certain anti-tumor effect.But the intensity of anti-tumor effect is feeble and is insufficient to inhibit the growth of tumor cells.Radiofrequency ablation therapy combined with special immunotherapies,such as immune stimulants,adoptive immunity cells therapy,dendritic cell vaccines,monoclonal antibodies and so on,can maximize the clinical benefit,which is a good pattern about tumor comprehensive treatment containing immunotherapy.

Objective To explore the clinical effect of flupentixol and melitracen(deanxit)combined with trimebutine maleate(TMB)in the treatment of patients with functional gastrointestinal disorders(FGID).Methods 135 patients with FGID were selected,and were divided into two groups accorded to the random number method,with 68 cases in the observation group and 67 cases in the control group.The control group was treated with oryzanol and vitamin B6 ,while the observation group was treated with deanxit combine with TMB on the basis of the control group. Main symptoms of postprandial discomfort,early satiety,abdominal pain and burning sensation on the abdomen in the two groups before and after treatment were monitored,adverse reactions of two groups were recorded,and the total efficacy was evaluated after the end of treatment.Results The difference of postprandial discomfort,early satiety, abdominal pain and upper abdominal burning sensation integration between the two groups had no statistically significant before treatment(all P >0.05).After treatment,the postprandial discomfort,early satiety,the abdominal pain and epigastric burning sensation were (4.1 ±1.6)points,(3.4 ±1.1)points,(4.2 ±1.2)points and(4.4 ± 0.7)points in the observation group,which were better than (5.9 ±2.4)points,(5.3 ±1.6 )points,(6.0 ± 1.2)points and(6.1 ±0.5)points in the control group(t =3.057,4.791,5.196,9.681,all P <0.05).The total efficacy was 94.1%(64 /68)in the observation group,which was better than 77.6%(52 /67)in the control group(χ2 =7.603,P <0.05).The difference of adverse reaction rates between the two groups had no statistically significant(P >0.05).Conclusion Deanxit combine with TMB can significantly improve symptoms in patients with FGID,and has a significant effect,thus it is a safe and effective therapy.
