Objective To investigate the correlation between uric acid level and macrovascular disease in type 2 diabetic patients.Methods Sixty type 2 diabetic patients with lower limb atherosclerosis of carotid artery were randomly selected in study group who hospitalized in the First Hospital of Zibo from Mar.to Feb.2012.Sixty type 2 diabetes mellitus(T2DM) without carotid and lower limb athemsclerosis were served as control group.The blood pressure,blood lipid,blood glucose and other biochemical indexes,including blood uric acid,serum insulin (FNS),fasting blood glucose (FPG),apolipoprotein a (LP (a)),apolipoprotein A1,B (APO-A1,APO-B),glycosylated hemoglobin (HbA1c),high density lipoprotein cholesterol (HDL-C),low density lipopmtein cholesterol (LDL-C),triacylglycerol (TG) and total cholesterol (TC) were measured and determined.Results There was no significant difference in terms of blood pressure,blood lipid levels,APO-A1,APO-B,HbA1C,FNS and FPG in study group patiems (P ＞ 0.05).The level LP(a) in study group was (0.4 ± 0.2) g/L,significantly higher than that in control group ((0.2 ± 0.2) g/L; t =3.842,P ＜ 0.01).The blood uric acid level in study group was (362.3 ± 112.8)mmol/L,significantly higher than that of the control group((284.8 ±68.6)mmol/L;t =3.188,P＜0.01).Conclusion Uric acid and LP(a) are involved in the oocurrence and development of athemsclemsis,which is close related to the development of type 2 diabetic macmangiopathy.Therefore,in the process of preventing type 2 diabetes with macroangiopathy,we should pay attention to uric acid and LP (a) of the patient beside effective control of blood glucose,blood pressure,blood lipid level.

The hypertension is one of chronic vascular diseases, which often implicates multiple tissues causing stroke, cardiac hypertrophy, and renal failure. A growing body of evidence suggests that inflammatory mechanisms are important participants in the pathophysiology of hypertension. In this study, the inflammatory status of these tissues (kidney, liver, heart, and brain) in spontaneously hypertensive rats (SHR) was analyzed and its molecular mechanism was explored. The tissues were dissected from SHR and age-matched control Wistar-Kyoto (WKY) rats to investigate the abundance of inflammation-related mediators (IL-1beta, TNFalpha, ICAM-1, iNOS, C/EBPdelta and PPARgamma). mRNA levels were determined by reverse transcription-polymerase chain reaction and protein expression was evaluated by Western blot. To evaluate the oxidative stress of tissues, carbonyl protein content and total antioxidant capacity of tissues were detected by spectrophotometry and ferric reduction ability power (FRAP) method. The results suggest that: (1) Expressions of inflammation-related mediators (IL-1beta, TNFalpha, ICAM-1, iNOS, C/EBPdelta and PPARgamma) in SHR were higher compared with those in WKY rats except no evident increase of IL-1beta mRNA in liver and brain in SHR. (2) Tissues in SHR contained obviously increased carbonyl protein (nmol/mg protein) compared to that in WKY rats (8.93+/-1.08 vs 2.27+/-0.43 for kidney, 2.23+/-0.23 vs 0.17+/-0.02 for heart, 13.42+/-1.10 vs 5.72+/-1.01 for brain, respectively, P<0.05). However, no evident difference in the amount of carbonyl protein in liver was detected between SHR and WKY rats. (3) Total antioxidant capacities of kidney, liver, heart and brain were markedly lower in SHR than that in WKY rats (P<0.05). Thus, the present data reveal a higher inflammatory status in the important tissues in SHR and indicate that inflammation might play a potential role in pathogenesis of hypertension and secondary organ complications.

OBJECTIVEThe purpose of this study was to search for a perfect treatment for the complications after polyacrylamide hydrogel injection for augmentation mammaplasty.

METHODS48 patients who accepted polyacrylamide hydrogel injection for augmentation mammaplasty were included in this study. Operations were performed for the complications of polyacrylamide hydrogel injection. The clinical data were analyzed and the experience in the treatment of the complications was summarized.

RESULTSAll patients were satisfied with the result of the operation. The B-ultrasonic examination showed that no visible polyacrylamide hydrogel remained in the cavity.

CONCLUSIONThe best therapy for the complications of polyacrylamide hydrogel injection was removing of the polyacrylamide hydrogel and the pathologic tissue and irrigation of the cavity.

OBJECTIVETo construct a function model that can be used in the diagnosis bladder outlet obstruction (BOO) resulting from benign prostatic hyperplasia, and to develop a diagram allowing the judgement of bladder outlet for patients with different detrusor contractility, especially with impaired one.

METHODSUrodynamic and clinical data of 131 men were analyzed retrospectively. By Logistic analysis, a function model was constructed. Based on the model, a diagram allowing the evaluation of bladder outlet was drawn. The cutoff point for diagnosing BOO with the function model and the curve was confirmed by ROC curve analysis.

RESULTSThe function model (BOOI) was obtained by the formula 5.03 x residual fraction + 0.04 x PdetatQmax - 0.20 x Qmax - 0.91 + alpha (alpha = 0 for those with low pressure-low flow on P-FS, alpha = 1.42 for high pressure-low flow, alpha = -7.30 for high pressure-high flow). The cutoff point for BOOI diagnosing BOO was 0.36. When validated, the sensitivity, specificity, positive predictive value, and negative predictive value were 85.7%, 91.7%, 96.0% and 73.3% respectively.

CONCLUSIONThe BOOI, with an easy calculation mode, could predict the probability of BOO. The sensitivity and specificity of the criterion for the diagnosis of BOO were satisfactory. The curve we drew could help to differentiate the obstructed men with low pressure-low flow and thus benefit them by surgical relief of their obstruction.

BACKGROUNDThe chronic pathological changes in vascular walls of hypertension may exert destructive effects on multiple organ systems. Accumulating evidence indicates that inflammatory reactions are involved in the pathological changes of hypertension. Three peroxisome proliferator-activated receptors (PPARs) have been identified: PPARalpha, PPARbeta/delta, and PPARgamma, all of which have multiple biological effects, especially the inhibition of inflammation. The aim of this study was to evaluate PPAR isoforms expression profile in important organs of spontaneously hypertensive rats (SHR) and to understand the modulation of endogenous PPAR isoforms under inflammatory condition.

METHODSTissues (kidney, liver, heart, and brain) were dissected from SHR and age-matched control Wistar-Kyoto rats (WKY) to investigate the abundance of PPAR isoforms and PPAR-responsive genes (acyl-CoA oxidase and CD36). The expression of CCAAT/enhancer-binding protein delta (C/EBPdelta), which can trans-activate PPARgamma expression, was also observed. The inflammatory response was analyzed by the expression of inflammatory mediators inducible nitric oxide synthase (iNOS), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, interleukin-1 beta (IL-1beta), and tumor necrosis factor alpha (TNFalpha), and formation of carbonyl and nitrated proteins.

RESULTSThe expressions of 3 PPAR isoforms and PPAR-responsive genes were markedly upregulated in SHR compared with those of WKY. Specifically, the expression of PPARalpha protein in the kidney, liver, heart and brain increased by 130.76%, 91.48%, 306.24%, and 90.70%; PPARbeta/delta upregulated by 109.34%, 161.98%, 137.04%, and 131.66%; PPARgamma increased by 393.76%, 193.17%, 559.29%, and 591.18%. In consistent with the changes in PPARgamma, the expression of C/EBPdelta was also dramatically elevated in SHR. Inflammatory mediators expressions were significantly increased in the most organs of SHR than WKY. As a consequence, increased formation of carbonyl and nitrated proteins were also observed in the most organs of SHR.

CONCLUSIONSThese findings suggest an enhanced inflammatory response in the organs of SHR, which might play a key role in pathogenesis of hypertension and secondary organ complications. Changes (increases) in PPARs expression may reflect a compensatory mechanism to the inflammatory status of hypertensive rats.

OBJECTIVETo study the preventive effect of chitosan on capsular contracture after implantation of silicone gel-filled mammary implants in rats.

METHODS18 SD female rats were divided into three groups randomly. Small silicone gel-filled mammary implants were implanted under each side of latissimus dorsi muscle. Chitosan was injected into left cavities as experimental sides, and nothing was injected into right cavities as control sides. 4, 8 and 12 weeks postoperation, specimens were dissected and observed using light microscope, and area density of collagen both type I and type III were also detected.

RESULTSFibrous capsules around implants consist of two layers: dense layer and loose layer. 4 weeks postoperation, total thickness of the experimental sides was less than that of the control sides (P < 0.01). Area density of collagen either type I or type III of the experimental sides was lower than that of the control sides (P < 0.01). Both 8 and 12 weeks postoperation, total thickness of the experimental sides was less than that of the control sides (P < 0.05). Area density of collagen type I of the experimental sides was lower than that of the control sides (P < 0.05). Area density of collagen type III was of no statistical difference between the experimental sides and the control sides (P > 0.05).

CONCLUSIONSChitosan can remarkably prevent capsule contracture during the early period after implantation of silicone gel-filled mammary implants.

OBJECTIVETo explorer the effectiveness of enriched bone marrow stem cells technique for lumbar fusion.

METHODSWith the randomization and control principles, 2 graft materials [Enrichment bone marrow mesenchymal stem cells hybridized with beta-tri calcium phosphate (composite graft group), autologous iliac crest bone graft (autograft group)] were compared in posterior lumbar fusion procedures. 56 patients with degenerative disc disease, lumbar instability or spinal stenosis, were included. The volume of cells suspension in pre- and post-enrichment and the number of nucleated cells (NCs) were identified. The number of osteoprogenitor cells was estimated by counting the colony-forming units which express alkaline phosphatase (CFUs/ALP+). Then the efficiency of the enrichment was evaluated. Clinical follow-up with roentgenogram and Oswestry scale scores was performed for outcome evaluation.

RESULTS(249 +/- 31) ml bone marrow per patient from bilateral iliac crests was aspirated peri-operatively. About (43 +/- 11) ml enriched bone marrow was collected. The number of NCs was concentrated from (15.9 +/- 3.3) x 10(6)/ml to (44.1 +/- 10.8) x 10(6)/ml, CFUs/ALP+ was significantly increased from (118 +/- 86)/ml to(486 +/- 305)/ml. The follow-up was about (26.3 +/- 7.5) months. There was no significant differences in age, gender, disease and fusion segments between the two groups. The fusion rate was 93.3% and 96.2% for composite graft group and autograft group, respectively (chi2 = 0.2146, P = 0.6432). There was no difference in operation time between the two group (t = 0.5243, P = 0.6022), but blood loss in composite graft group was more than that in autograft group (t = 6.4664, P < 0.01). Cell salvage for auto-transfusion could transfuse back half of the blood loss during operation. No hematoma or chronic soreness in the bone marrow donor sites of composite graft group occurred, but a little exudation or moderate swelling in the wound happened in 4 cases which disappeared under medical treatment. Meanwhile, 15.4% patients had hematoma in the iliac bone donor site and 26.9% patients had chronic soreness, but no case had wound problem in autograft group. As for Oswestry scale scores, there was no significant difference between the two groups.

CONCLUSIONSThe enrichment technique of autologous bone marrow stem cells can greatly increase the concentration of MSCs. It is a rapid and safe method used peri-operatively. The composite material of enriched MSCs and porous beta-TCP is a good bone substitute in posterior spinal fusion.

OBJECTIVETo evaluate the risk factors of postoperative renal failure (RF) in the patients with type A dissection of aorta operated on with cerebral perfusion and deep hypothermia circulatory arrest (DHCA).

METHODSFrom January 2004 to October 2007, 157 patients with type A dissection of aorta underwent surgical procedures with cerebral perfusion and DHCA. There were 115 male patients and 42 female patients with the age from 17 to 76 years old. Antegrade selective cerebral perfusion through axillary artery was performed for 129 patients and retrograde cerebral perfusion from superior cava vein was performed for 28 patients. All the factors underwent univariate and multivariate analysis.

RESULTSMean cardiopulmonary bypass duration was (188.0 +/- 10.8) min and mean cerebral perfusion time was (36.0 +/- 3.1) min. Fifteen patients died in hospital and the hospital mortality was 9.6%. Permanent neurological dysfunction (PND) occurred in 8 patients (5.1%). Postoperative RF was observed in 20 patients (12.8%). Multivariate analysis showed the preoperative renal dysfunction (P = 0.042, OR = 4.41) and over seventy-year-old patients (P = 0.049, OR = 4.94) were found to be the risk factors of postoperative RF. There was a higher incidence of death (45%, P = 0.001) and PND (25%, P = 0.009) in the patients of postoperative RF when compared with the other patients.

CONCLUSIONThe preoperative renal dysfunction and elderly patients were found to be the risk factors of postoperative RF after type A dissection of aorta surgery.
