Objective To explore the different effects on the bleeding after the surgery of minimally invasive intracranial haematoma with drainage method.Methods The cases with minimally haematoma invasive operation were divided into A and B group.Group A simply used the liquefaction agent for blood clots( urokinase mixed with hyaluronidase),without washing step,and Group B used saline water to wash repeatedly and then use liquefaction agent to divert.Results The hematoma clearance rate of A group equal to that of B Group,while the rate of re-bleeding was ( 3.8 ％ ) obviously lower than than of B Group ( 22.7％ ) ( x2 =4.594,P ＜ 0.05 ).Condusion For many cases who have experienced the minimally invasive intracranial operation,the simple use of liquefaction agent can divert haematoma,and the risky rate of re-bleeding was obviously lowered.

BACKGROUND:Previous studies have found that the basement membrane matrix can induced the chondrogenic differentiation of bone marrow mesenchymal stem cels, but there is a wide gap between its mechanical properties and practical application, and further research is needed. OBJECTIVE:To prepare a suitable matrigel/chitosan scaffold that has appropriate mechanical properties and remarkable bioactivity for cartilage repair. METHODS: We selected genipin as cross-linking agent, and mixed Matrigel with cross-linked chitosan at different ratios (2:1, 1:1, 1:3). Then rat bone marrow mesenchymal stem cels were seeded on different scaffolds and cultured for 14 days. The mechanical properties of materials were measured by DMA. Cel counting kit-8, FDA staining, ELISA kits and Alcian blue staining were used to measure the bioactivity of materials. RESULTS AND CONCLUSION:The storage modulus of scaffolds was raised from 0.48 kPa to 1.78 kPa with increase ratio of chitosan. Cels spread wel in the early period on al scaffolds, and then the cels on the chitosan scaffold showed reduced chondrogenic activity, but cels on the scaffolds with matrigel could maintain chondrogenic differentiation. The matrigel/chitosan scaffold at a ratio of 1:1 had appropriate mechanical properties and higher levels of colagen II and colagen X at 14 days. The prepared matrigel/chitosan scaffold with decent mechanical performance can promote the differentiation of bone marrow mesenchymal stem cels into chondrogenic lineages, which can be used in cartilage tissue engineering.

Objective To study the methods and efficacy of selective or superselective renal artery embolization for renal neoplasms,abcesses and bleeding. Methods Sixty cases of renal carcinomas and 4 cases of abcesses were all treated with selective renal artery embolization before surgery,and 3 cases of advanced renal carcinomas were treated with selective renal artery embolization alone.Embolization materials for carcinoma and abcesses were mainly gelfoam.Nine cases of renal angiomyolipomas,23 of traumatic renal hemorrhages,1 undergoing extracorporeal shock-wave lithotripsy (ESWL) and 2 nephrolithotomy,all of whom had severe hematuria,were treated with selective or superselective renal segment artery embolization.Embolization materials for hemorrhages were mainly self-blood clots and(or) gelfoam,and the materials for angiomyolipoma were pure alcohol and(or) gelfoam. Results The sizes of carcinomas and abcesses were decreased in all of the 60 cases of renal carcinomas and 4 cases of renal abcesses.The edema around the carcinomas and abcesses became obvious,and bleeding was reduced,which were convenient for operation and prolonged survivals.All the renal bleeding were cured with selective or superselective renal artery embolization except for one traumatic case treated by operation for continuous bleeding.All these cases were followed up for 1 month to 18 years.One case had mild atrophy of kidney and in one case IVU didn't develop.All the others were in good condition. Conclusions Selective or superselective renal artery embolization is a safe,effective approach with less complications and most probability to preserve the diseased kidney. Renal artery embolization as a valuable treatment should be studied and widely applied.

Aim Tostudytheeffectsofferulicacid (FA) on doxorubicin (DOX) induced cellular injury inH9c2ratmyocardialcells.Methods H9c2cells were treated with 1μmol·L-1 DOX treated for 24 h to establish a myocardial injury model. 10, 20, 40μmol ·L-1 FA was added 2 h before DOX treatment. Cell viability was measured by cell counter kit ( CCK-8 ) . Morphological changes were observed by phase contrast microscope. LDH, CK, MDA, SOD levels were detec-ted by biochemical kits. Intracellular level of reactive oxygen species ( ROS) was examined by DCF-DA stai-ning with flow cytometry. Cellular apoptosis was detec-ted by AO-EB staining and DNA agarose gel electro-phoresis. The expression of caspase-3, Bax, Bcl-2 was evaluatedbyWesternblot.Results Exposureof H9c2 cells to DOX led to decrease in cell viability, in-crease in stress and apoptosis. FA pre-treatment im-proved cell viability in a dose-dependent manner, at-tenuated leakage of LDH and CK, and reversed mor-phological changes induced by DOX. FA suppressed DOX-induced oxidative stress as evidenced by reducing ROS and MDA generation and increasing SOD enzyme activity. FA depressed myocardial apoptosis by down-regulating pro-apoptotic protein caspase-3 and Bax, whereas up-regulating apoptosis inhibitory protein Bcl-2.Conclusions FAhasaprotectiveeffectonDOX-induced injury in H9c2 cells. This protection may re-sult from inhibition of myocardial oxidative stress and apoptosis.

Objective To quantitatively assess the left ventricular systolic and diastolic function in the elderly patients with dilated cardiomyopathy (DCM) by using Doppler tissue imaging (DTI) and to explore its clinical value. Methods A total of 20 normal controls and 22 old patients with DCM were enrolled in the study. The left ventricular end-diastolic diameter (LVEDd), left atrial diameter (LAD) and left ventricle ejection fraction(LVEF) were obtained by routine echocardiogram. And the systolic and early diastolic peak velocity (Vs and Ve) were detected by quantitative tissue velocity imaging (QTVI) and the mean value was accounted. The systolic mitral valve displacements (MVD) in 6 sites were determined by tissue tracking technique and the mean value was calculated. Results The LVEDd and LAD were significantly higher in DCM group than in normal group [LVEDd: (67.56±10.27) mm vs. (43.36±4.20) mm; LAD: (49.91± 6.27) mm vs. (32.00+4.53) mm, t=10.229 and 10.359, both P<0.01]. And the LVEF, Vs and MVD were lower in DCM group than in normal group [LVEF: (26.50 ± 8.25)% vs. (64.00 + 4.72)%; Vs:(5.14+1.30) cm/s vs. (8.89+1.87) cm/s; MVD:4.82+1.85 vs. 10.23± 1.95, t=18.502, 7.716 and 8.143, all P< 0.01].The Vs and MVD were significantly positively correlated with LVEF (r=0.78 and 0.89, both P<0.01). Conclusions DTI can quantitatively assess global and regional left ventricular systolic and diastolic function of elderly patients with DCM, and provide the reliable information for the judgment of pathogenetic condition.

Objective The retrograde isolated hepatic perfusion (RIHP) model was used to compare with the isolated hepatic perfusion (IHP) model in reducing the rate of normal hepatic tissue toxicity and peripheral drug leakage during chemotherapy in rat liver. Methods A total of 90 male Sprague-Dawley rats weighing 300-350 g were randomized into 3 groups with 30 rats in each. Group A: perfusion with Lactated Ringer'S Solution through arteria hepatica (RA) and portal vein (PV),the inferior vena cava was used as an outflow tract of perfusate. Group B: For isolated hepatic perfusion (IHP), Fluorouracil (5-FU) was added into the perfusate at a dose of 350mg/kg and introduced in to the liver through arteria hepatica, portal vein was perfused by Lactated Ringer'S Solution, and the inferior vena cava was used as an outflow tract of perfusate. Group C: by using retrograde isolated hepatic perfusion (RIHP), the solution which contains 350 mg/kg Fluorouracil (5-FU) was also introduced through arteria hepatica, the inferior vena cava was introduced with Lactated Ringer'S Solution;the portal vein was used as an outflow tract of the perfusate. On day 1, 3, 5 and 7 after the perfusion in all groups, blood serum ALT test and liver histopathology test were performed. The peripheral blood drug levels were measured with high performance liquid chromatographic(HPLC) system in group B and group C. Results The survival rate was 90%, 86.7% and 90% in group A, B and C,respectively. No statistically significant difference was observed in the survival rate among the 3groups. In all the three groups, serum ALT levels were the highest on the first day after IHP: (481.6±207.6)μmol/LingroupA;(1641. 6±658.0) μmol/LingroupBand( 913. 0±353. 5)μmol/Lin group C. Significant higher serum ALT levels were observed by comparing group B and C with A(P＜0. 05). Meanwhile, the serum ALT levels were significantly higher in group B than in group C (P＜0.05). The peaks of peripheral blood drug concentration during the perfusion were 131.2±29.4μg/ml in group B and 65.3±28. 4μg/ml in group C. Significant difference was observed (P＜0. 05). Liver biopsies of group A showed mild changes on the first day after IHP and returned to normal after 7 days. Group B showed severe changes on the first day after IHP and local necrosis still existed after 7 days. Group C showed moderate changes as compared with group B on the first day after IHP and also returned to normal after 7 days. Conclusion Retrograde isolated hepatic perfusion (RIHP) can reduce the liver toxicity compared to isolated hepatic perfusion (IHP). Hopefully, RIHP will be considered as a safer way in regional chemotherapy in liver cancer.

AIM: To investigate antitumor effect of allotri-tridecyl diethylamine (D-108) in vivo and in vitro. METHODS: The cytotoxic effects of D-108 on various tumor cell lines, human gingival fibroblast and marrow stromal cell cultured in vitro were determined with trypan blue dye exclusion test and MTT method. The acute toxicity of mice by administration of D-108 was evaluated by Bliss method. At a tolerable dose level, D-108 was administrated to treat transplanted solid tumor U14, and tumor weight inhibition was observed. Apoptosis morphological transformation of HL 60 cell induced by D-108 was detected by the Giemsa staining. RESULTS: The cytotoxic effects in vitro of D-108 on various tumor cell lines (IC_ 50 : 0.22 to 2.19 mg?L~ -1 ) were more powerful than both human gingival fibroblast and marrow stromal cell (IC_ 50 : 5.55 and 3.57 mg?L~ -1 ). LD_ 50 of D-108 was 36.49 mg?kg~ -1 (mice, i.g.). D-108 inhibited in vivo growth of implanted solid tumor U14 of mice effectually. The inhibition rate of tumor weight of D-108 (100 mg?kg~ -1 ?d~ -1 i.g.) was 45.27 %. HL 60 cell appearanced typical apoptosis morphological transformation induced by D-108. CONCLUSION: D-108 had obvious antitumor activity in vivo and in vitro and little toxicity. D-108 could induce the apoptosis of HL 60 cell.

AIM:To investigate the changes of CD27 and CD28 expression on cytokine-induced killer(CIK) cells and natural killer(NK) cells during cultivation.METHODS:The mononuclear cells were treated with interleukin-12(IL-2),IL-7,IL-15,stem cell factor and FLT3 ligand for four weeks. The CD27 and CD28 expression on CD3+CD56+ CIK cells and CD3-CD56+ NK cells were examined by flow cytometric analysis every week during four-week cultivation.RESULTS:The expression of CD27 on CIK and NK cells two weeks after cultivation reached the peak value at(44.57?4.07)% and(51.02?5.20)%,respectively. Then,their expression declined gradually to about 30% in the fourth week. The expression of CD28 on CIK and NK cells reached the peak at the third and the second week,the values were (4.40?0.66)% and (45.14?3.58)%,respectively,decreased rapidly and then were almost completely lost at the fourth week. CONCLUSION:According to the changes of expressions of CD27 and CD28 on CIK/NK cells,optimal harvest time of cultured CIK/NK cells should be at the third week of cultivation.
