Objective To summarize the efficacy of epirubicin chemotherapy by intra-iliac arteral infusion for the high risk patients of postoperative bladder cancer. Methods Eighty-six patients with the bladder cancer at high risk of recurrence who had undergone the bladder-sparing surgery were divided into two groups.Thirty-one patients were treated by intra-iliac arterial infusion chemotherapy of epirubicin and the remaining 55 patients had no chemotherapy.An analysis on recurrence related factors was made by multivariate Cox regression analysis models.And Kaplan-Meier curves were compared using the log-rank test on the disease-free between the two groups. Results Multi-recurrence associated with a higher grade and postoperative intra-iliac arterial infusion chemotherapy of epirubicin were significantly important factors,the former being risk factor and the latter being protective factor of cancer recurrence in bladder respectively.The recurrence of 9 in 31 patients (29%) with intra-iliac arterial infusion chemotherapy of epirubicin was significantly lower than that of 30 in 55 patients (54%) without chemotherapy ( P

Objective To evaluate the model for end-stage liver disease (MELD) and MELD combined with serum natrium level (MELD-Na) in predicting short-term prognosis of liver failure.Methods Clinical data of 322 patients with liver failure admitted in the First Affiliated Hospital of Xinjiang Medical University from April 2003 to April 2012 were retrospectively analyzed.MELD and MELD-Na scores were calculated at diagnosis and one week after the diagnosis,and then △MELD and △MELD-Na were determined.Receiver operating characteristics (ROC) curve and Kaplan-Meier survival curve were used to evaluate the value of the above scores in predicting 3-month prognosis.Results The 3-month mortality rates of acute/sub-acute,acute-on-chronic and chronic liver failure were 77.4％ (24/31),41.7％ (50/120) and 56.1％ (96/171),respectively,and the difference was of statistical significance (x2 =14.273,P ＜0.01).For acute/sub-acute liver failure,the areas under ROC curve (AUCs) were 0.699-0.836 for each scoring system in predicting short-term prognosis,and no significant difference was observed (Z =0.507,0.622,0.712,0.727,0.779 and 0.599,P ＞0.05).For acute-on-chronic liver failure,AUCs were 0.889 and 0.897 for △MELD and △MELD-Na in predicting short-term prognosis,which were higher than those of MELD and MELD-Na scores at the baseline (Z =3.110 and 3.500,P ＜ 0.05),but no significant difference was observed between △MELD and △MELD-Na (Z =0.310,P ＞ 0.05) ; Kaplan-Meier survival curve showed that the 3-month mortality rate for patients with △MELD ＞ 3.5 was 87.8％,and the average survival time was 34.05 d.For chronic liver failure,AUC of △MELD was 0.871 in predicting short-term prognosis,which was higher than that of △MELD-Na (Z =4.229,P ＜0.05) ; Kaplan-Meier survival curve showed that the 3-month mortality rate for patients with △MELD ＞ 4.5 was 89.9％,and the average survival time was 29.08 d.Conclusion For acute/sub-acute liver failure,MELD,MELD-Na,△MELD and △MELD-Na are all satisfactory in predicting short-term prognosis; for acute-on-chronic liver failure,△MELD and △MELD-Na are better than MELD,MELD-Na scores at the baseline; and for chronic liver failure,△MELD is the best indicator.

Objective To explore the possible pathway and regulatory mechanism of dermal fibroblasts' transdifferentiation into myofibroblasts induced by estrogen. Methods Human dermal fibroblasts were divided into six groups (A: control; B: estrogen; C: estrogen + ICI-182780; D: estrogen + SB203580; E: estrogen + PD98059; F: estrogen + SP600125). The cells were collected for RNA extraction and the expression of α-SMA was detected by real time quantitative RT-PCR. Some cells were analyzed by single cell RT-PCR to detect positive expression percentage of α-SMA.Results The expression and positive rate of α-SMA in estrogen group were significantly increased (Group B vs. Group A, 7. 385±0. 246 vs 1. 367±0. 034, P＜0.01) and those in ICI-182780 group and SP600125 group were significantly inhibited (Groups C and F vs. Group B, 4. 619 ±0. 164,2. 409±0. 091 vs 7. 385±0. 246, P＜0. 05). Conclusions In the process of fibroblast transdifferentiation into myofibroblasts induced by estrogen, estrogen β receptor and JNK-MAPK signal transduction pathway may play an important role.

Associations between "lipid-related" candidate genes, blood lipid concentrations and coronary artery disease (CHD) risk are not clear. We aimed to investigate the effect of three newly identified lipids loci from genome-wide association studies on CHD and blood lipid levels in Chinese Han population. The genotypes of SNPs at three newly identified lipid loci and blood lipids concentrations were examined in 1360 CHD patients and 1360 age- and sex-frequency matched controls from an unrelated Chinese Han population. Allele T of rs16996148 occurred less frequently in CHD patients with the odds ratio (OR) being 0.64 (95% CI 0.50 to 0.81), after adjusting for conventional risk factors and was associated with a 33% decreased CHD risk (P<0.01) comparing with the major allele G. Individuals with GT genotype had the lowest CHD risk. No associations were found between the polymorphisms of other two loci with CHD risk and all three SNPs had no effect on lipid profile in this population. SNP rs16996148 on chromosome 19p13 is significantly associated with lower risk for CHD in Chinese Han population. However, it remains unresolved why these lipid-related loci had significantly less effects than the correspondingly expected effects on blood lipids levels in this population.

OBJECTIVE: To investigate the expressions of transforming growth factor beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2) in human mandible fracture callus and their quantity changes in the process of healing. METHOD: Thirty callus samples from the fractured mandible bone stumps were collected during operation, and two callus samples were collected from the angle-square jaw patients as controls. The expressions of TGF-beta1 and BMP-2 were test by the immunohistochemistry technic-SABC-staining in different periods of human fractured mandibular callus and in osseous tissue of normal angle of mandible. RESULT: The TGF-beta1 and BMP-2 were expressed in callus of different periods but not in normal bone tissue. The expression of TGF-beta1 increased slowly during the first three weeks after fracture and reached its maximum in the third week, and then weakened gradually. The expression of BMP-2 increased gradually during the first two weeks after fracture and reached its maximum in the second week, then the expression weakened gradually. CONCLUSION (1) BMP-2 may be one of the factors promoting the repair of fracture. (2) TGF-beta1 could be another signal pathway in repairment of fracture. (3) There could exist some synergistic effects between TGF-beta1 and BMP-2 in the process of fracture healing.

BACKGROUND:Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations stil exist.
OBJECTIVE:To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cel transplantation for bone nonunion after fracture surgery.
METHODS:Clinical and fol ow-up data from 69 patients with bone nonunion were analyzed retrospectively. Al patients were al otted to combination (n=37) and iliac (n=32) groups, fol owed by treated with autologous iliac crest graft combined with autologous bone marrow stem cel transplantation or autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve cal us scores were detected and compared between groups.
RESULTS AND CONCLUSION:The hospitalization time did not differ significantly between groups (P>0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P<0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P<0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P<0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs.

This study was aimed to observe the protective effect of extract from Rhizoma A nemones Raddeanae (RAR) on hepatic fibrosis induced by porcine serum in rats. A total of 68 SD rats were randomly divided into 5 groups, which were the normal group, model group, RAR group, extraction of RAR (EXRAR) group, Fu-Zheng Hua-Y u(FZHY) group. Each rat was intraperitoneally injected with 0.5~0.6 ml of porcine serum twice a week for 15 suc-cessive weeks to establish liver fibrosis model. Intragastric administration was given after the model was successfully established. The FZHY group was given FZHY capsule (0.525 g·kg-1). The RAR group was given RAR decoction (0.7 g·kg-1). The EXRAR group was given EXRAR (0.071 g·kg-1). The model group and normal group were given e-qual amount of physiological saline. The medication was given once a day. And the treatment course was 8 weeks. At the end of the 23th week, rats were sacrificed. Contents of SOD and MDA in blood serum were assayed. The protein expressions of α-SMA and TGF-β1 in liver tissues were detected by SABC. The results showed that compared with the model group, content of MDA decreased in the EXRAR group, RAR group and FZHY group (P<0.05), and content of SOD increased obviously (P<0.05). In the model group, expression of α-SMA and TGF-β1 increased, with dark brown dyeing and diffusion area. Expression area and strength of the FZHY group, RAR group, and EXRAR group were ob-viously weak with tasteless interval dyeing and no formation of typical pseudolobule in comparison with the model group. The color rendering index showed that compared with the model group, the protein expression of α-SMA and TGF-β1 decreased obviously in liver tissues of the FZHY group, EXRAR group, and RAR group (P< 0.05). It was concluded that RAR and its extract had a good antifibrosis effect. And the EXRAR had basically the same antifibrosis effect as RAR. It was assumed that the possible mechanism was related with the inhibiting of hepatic stellate cell (HSC) activation and the expression of TGF-β1 as well as the resisting of lipid peroxidation.
