The mean amount of blood transfusion, hospitalization days and expenses were (2.5?0.8)U,(13.2?1.3)d and (5 250?335) yuan, respectively. Seventy-four cases were treated with operation and 68(91.2 %)were cured, there were 14 cases (20.6 %) with complications among the 68 cases who were cured. The mean amount of blood transfusion,number of hospitalization days and expenses were (8.4?1.1)U,(15.4?0.9)d and (13 550?805) yuan,respectively.The mean amount of blood transfusion and hospitalization expenses of nonoperative group were lower than those of operative group (P

Objective To study the expression of membrane molecules of T lymphocytes of cord blood after low dose irradiation(LDI). Methods Freshly isolated lymphocytes from cord blood were irradiated with 62mGy gamma-ray. At different time(4h; 12h;24h) after irradiation, the changes of TCR+, CD3 +, CD4 +, CD8 + cells were examined by flow cytometry with direct immunofluorescence, respectively. Results The proportion of CD3 +, TCR+ /CD3 +; CD4 +, CD8 + cells increased significantly after LDI,the most obvious enhancement was noted in the 24h experimental group were no significant changes in the ratio of CD4 to CD8. Conclusions It is suggested that expedition of the maturation, activation and signal transudation of T lymphocytes from cord blood can be induced by ir- radiation with 62mGy gamma-ray The reconstruction of immune functions after cord blood transplantation may be ac- celerated, enhancing the graft versus leukemia(GVL)effect and preventing the tumor from relapsing.

Objective To evaluate the effect of pediatric renal transplantation using donation after cardiac death (DCD).Methods The male DCD meeting Chinese standard Ⅲ (C-Ⅲ) was 49 years old,and the recipient with chronic renal failure was 14 years old.The right kidney of the donor was transplanted to the recipient.The renal artery and renal vein of the donor were end-to-side anastomoscd to the common iliac artery and common iliac vein of the recipient,respectively.The graft was transplanted into the fight iliac fosse.Warm ischemia time was 12 min,and cold ischemia time was 2 h.Immunity induction therapy was performed with basiliximab.Tacrolimus + mycophnolate mofetil + Pred were used as immunosuppressive regimen.Results The transplantation was done successfully.One day after operation,ALT was increased dramatically.The recipient was diagnosed as acute drug-induced liver injury.There was no occurrence of acute rejection and delayed graft function.The recipient was discharged one month after the operation,and followed up for 6 months with normal graft function.Conclusion Pediatric renal transplantation using DCD is effective and safe,even though the long-term effect still needs to be further observed.

Objective To study the relationship between the CT value and injury of ultrastructure in posttraumatic acute diffuse brain swelling(PADBS). Methods The change of CT value of brain tissue was analyzed at posttrauma and preoperation in 9 patients, in combination with the ultrastructure in brain parenchyma in 36 specimen taken from operations. The relationship between the descend of CT value and ultrastructure injury was analysed.Results The CT value of brain in preoperation was lower than it in posttrauma first scanning(2.5～4.3 HU).The capillary distention and stenosis and the diffuse edema in pericapillary and intercellular were observed under transmission electron microscopy(TEM). The nucleolus of neuronal cells displaced to membrane or disappeard. Chromation agglutionation, nuclear membrane circuity, perinuclear diffuse lipid drops and blankspace were detected. The mitochondrion swelling, mitochondrial crest blurring or effacement, rough endoplasmic reticulum distension and its’ granules detachmen were also seen under TEM. Axolemma edema, microfilaments and microtubules derangement in axis-cylinder were found too. The similar phenomena existed in astrocyte.Conclusion The descent of CT value in PADBS was relevant to the aggravation of vasogenic cerebral edema, cytotoxic cerebral edema and ultrastructure injury in brain parenchyma.

Objective To assess the value of real-time myocardial contrast echocardiography (RTMCE) and intermittent triggered myocardial contrast echocardiography (ITMCE) in the detection of myocardial no-reflow phenomenon after reperfusion in acute myocardial infarction on mini-swine models. Methods Thirty close-chest mini-swines were used to create acute myocardial infarction and reperfusion model through interventional method. RTMCE and ITMCE were performed at baseline, 2 h after occlusion of left anterior descending coronary artery and 3 h after reperfusion. The myocardial perfusion defects after occlusion was measured as risk area (RA) and that after reperfusion was measured as no-reflow area (NRA). NRA/RA was calculated and compared with pathological findings. Results The whole study protocol was successfully performed in 27 mini-swines. NRA/RA obtained from RTMCE, ITMCE and pathological staining was (47.94±21.29)%, (38.20±21.04)% and (30.07±14.62)% , respectively. NRA/RA had no significant difference by ITMCE and pathological staining (P=0.124), RTMCE and ITMCE (P=0.071). The correlation coefficient of RTMCE and staining was 0.700 (P<0.001), ITMCE and staining was 0.765 (P<0.001), RTMCE and ITMCE was 0.897 (P<0.001). The sensitivity, specificity and accuracy in the detection of myocardial no-reflow was 100%, 58.33% and 79.17% for RTMCE, 91.67%, 73.33% and 81.48% for ITMCE. Conclusion Both RTMCE and ITMCE could be used as noninvasive methods to reveal the myocardial perfusion and quantitatively detect myocardial no-reflow after reperfusion therapy.

OBJECTIVE: To analyze the expression of microRNA-106a(miR-106a) in renal cell carcinoma (RCC) and its correlation with clinicopathological characteristics and prognosis of patients. METHODS: Serum samples of 64 patients with newly diagnosed RCC were collected as the study group, and serum samples of 40 healthy individuals were used as the control group. Real-time fluorescence quantitative PCR was used to determine the expression level of miR-106a in each group. The correlation between miR-106a expression and clinicopathological characteristics of the patients was studied with single factor analysis and multiple Logistic regression model. Kaplan-Meier survival curve was used to analyze its correlation with the prognosis of patients. RESULTS: Before surgery, compared with the control group (1.17± 0.58), RCC patients with high- (9.15± 0.96) and low-expression(3.45± 0.37) had increased expression of miR-106a. Postoperatively, the expression level of miR-106a in both groups of patients decreased to 1.53± 0.18 and 1.75± 0.21, respectively. The area under the curve (AUC) of the diagnostic value of serum miR-106a for RCC was 0.782 (95% CI: 0.661-0.902). With an optimal cutoff value of 0.531, the sensitivity was 78.10% and the specificity was 75.00%. Serum miR-106a level of RCC patients with TNM stage T3 or T4, clinical stage II or III, lymph node metastasis, and recurrence were significantly increased. The high expression of serum miR-106a in RCC patients has an independent relationship with the tumor TNM stage and lymph node metastasis. Of the 64 follow-up patients, 4 were lost and 30 had died. Among them, the median survival time of patients in the miR-106a high expression group was 30 months, which was significantly shorter than that of the low expression group (52 months). CONCLUSION The serum level of miR-106a is elevated in RCC patients, and may be used as a molecular marker for the diagnosis of RCC. High serum expression of miR-106a is an independent predictor for tumor TNM stage and lymph node metastasis, as well as an independent predictor for poor prognosis of RCC patients.

The present study determined the thyroid hormone interference of tetrabromobisphenol A (TBBPA) in Sprague-Dawley (SD) rats, and the derived-reference dose (RfD) of different endpoint effects on mammals based on experimental results and data collection. Based on repeated exposure toxicity tests on mammals and extensive research, the present study used BMDS240 Software to derive a benchmark dose, and analyzed the accuracy and uncertainty, and similarity with other studies. Test results on triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) demonstrated that all the indicators presented a non-monotonous dose-effect relationship clearly, except TSH in male rats exposed to 0-1000 mg/kg BW per day. Therefore, RfDs were derived from different critical effects. In summary, RfD for mammals in the present study was found to be 0.6 mg/kg per day.
