Objective To investigate whether functional Wnt-?-catenin signaling is present in activated hepatic stellate cells (HSC),and the effect of blocking this signaling on activation of HSC. Methods?-catenin expression in HSC was examined by immunocytochemistry.Wnt signalings in HSC-T6 were assessed using a T cell factor (TCF)-dependent luciferase reporter gene (pTOP- FLASH) assay.Wnt signalings in HSC-T6 were blocked by transfecting with a dominant negative TCF (dnTCF) expression plasmid,then the expression of alpha smooth muscle actin (?-SMA) and collagen typeⅠwere examined by Western blot.Results?-catenin staining was positive in the nuclei of HSC-T6.Luciferase activity in the cells transfected with pTOPFLASH was significantly higher than that in the cells transfected with pFOPFLASH (P

Objective To investigate the effects of antihypertension and reversing left ventricular hypertro- phy by carvedilol or bisoprolol in patients with mild to moderate essential hypertension.Methods 40 cases of mild to moderate essential hypertension patients were selected for this random single-blind,paralleling controlled clinical study.Results Patients were randomized to take 12.5~25mg carvedilol tablet orlce daily or bisoprolol 2.5~5mg once daily if DBP was still in the range of 12.0~14.6kPa(90~110mmHg)after 2 weeks' placebo baseline. Carvedilol group included 20 cases,bisoprolol group included 20 cases,and the course was 24 weeks.Blood pressure and heart rate were measured and symptoms and signs were recorded.At the end of placebo and in 24 weeks heart ultrasound,blood routine,serum glucose,blood lipid,hepatic function and renal function were examined.SBP,DBP and heart rate of patients in two groups decreased obviously.There were significant differences between the two groups.Ventricular hypertrophy of carvedilol group improved than that in pretherapy.There were significant differ- ences between the two groups.Conclusion Carvedilol was well-tolerated with less side effects such as mild headache,tiredness,dizziness,slightly elevating of serum glucose.Carvedilol could well treat the mild moderate essen- tial hypertension effectively and safely by 12.5~25mg once daily.

OBJECTIVETo observe the expression profiles of osteoblast-related genes in human mesenchymal stem cells (MSCs) derived from bone marrow during osteogenic differentiation.
METHODSMSCs were induced to differentiate with MSC osteogenic differentiation medium for 7, 14, 21 and 28 days respectively. Alizarin Red staining was used to detect matrix mineralization. Expression of osteoblast-related genes, including osteocalcin, osteopontin, Runt-related transcription factor 2 (Runx2), alkaline phosphatase and collagen type 1, was assessed with quantitative reverse transcription-polymerase chain reaction.
RESULTSOn day 14 after induction of differentiation, cells were stained positively with Alizarin Red. The expression levels of these genes exhibited an upward trend as induction time was prolonged. Exposure to osteogenic differentiation medium less than 21 days did not significantly induce osteocalcin expression; osteocalcin expression levels in the differentiated cells induced for 21 and 28 days were 1.63 and 2.46 times as high as the undifferentiated cells respectively (all P<0.05). Stimulation with MSC osteogenic differentiation medium over 14 days significantly enhanced bone marrow-derived MSCs to express osteopontin and Runx2 genes (all P<0.05). Osteogenic differentiation medium could significantly induce the expressions of alkaline phosphatase and collagen type1 genes (all P<0.05). Their expressions reached the peak levels on day 21, which were increased more than 4- and 3-fold respectively.
CONCLUSIONHuman bone marrow-derived MSCs could exhibit the sequential expression pattern of osteoblast marker genes during osteogenic differentiation in vitro.

Medical ethics is correlated with further development of affiliated teaching hospital.Our hospital took ‘ Bethune spirit’ and philosophy of forgiveness and kindheartedness as guidance and became the first batch of Bethune spirit model hospital of Chongqing.Teaching quality was improved by providing lectures about ‘ Bethune spirit’ for medical students and equally emphasizing medical knowledge and medical ethics education.Anti-corruption and academy governing movements with the subject of ‘ Bethune spirit’ were carried out to repel academic misdeed,with the result that clinical,teaching and scientific works were promoted and advanced.

Objective Toanalyzetheclinicalcharacteristicsandtreatmentoutcomesofspinalfilum terminalevascularmalformation.Methods Theclinicaldataof6patientswithfilumterminalevascular malformation diagnosed and treated from January 2008 to December. 2013 were analyzed retrospectively. The definition of filum terminale vascular malformation is anterior/posterior spinal artery feeding arteriovenous fistula or arteriovenous malformation and located below conus medullaris,and does not complicate with spinal vascular lesions in the other part. The Aminoff & Logue score and MRI of spinal cord function were performedatoneyearaftermicroneurosurgeryand/orendovascularembolization.Results Allpatients were males. Their clinical presentations were the weakness of both lower extremities and sphincter disturbance. The mean course of disease was 17. 1 ± 5. 2 months. The pathological type of the 6 patients were all arteriovenous fistulas. The feeding arteries included lumbar artery,internal iliac artery,and median sacral artery. Two of the 6 patients underwent Onyx glue embolization,3 were treated with microneurosurgery,and 1 was treated with embolization in combination with microneurosurgery. They were all achieved anatomic cure. The Aminoff & Logue scores were improved after 1 year (3. 8 ± 1. 9 scores before procedure,2. 8 ± 2. 0 scores after procedure),there was no significant difference (P >0. 05). The myodynamia scores were improved in 3 patients,2 did not change,1 got worse. The urinary and bowel functions were improved in 2 patients,and4didnotchange.Conclusion Filumterminalevascularmalformationisararevascular malformation of spinal cord. Both embolization and surgical treatment can achieve anatomic cure. Although the spinal cord function can be only partially restored,but continuous deterioration can be prevented.

This study aims to explore the efficacy of interferon-α (IFN-α) combined with either entecavir (ETV) or adefovir (ADV) therapy versus IFN-α mono-therapy for chronic hepatitis B (CHB) patients,and to identify the factors associated with treatment outcomes.Totally,159 CHB patients receiving interferon-based treatment for 48 weeks were enrolled in this retrospective study,including IFN-α mono-therapy group (group A,n=44),IFN-α plus ADV group (group B,n=53) and IFN-α plus ETV group (group C,n=62).The primary measures of efficacy assessments were the changes in HBsAg.Cox regression analysis was used to identify the predictors of treatment outcomes.The predictive values of the factors were assessed by ROC analysis.For patients with baseline hepatitis B surface antigen (HBsAg) level <1000 IU/mL,the reductions in mean HBsAg levels at week 48 were greater in group C than that in group A (P<0.05).Higher rate of HBeAg seroconversion was achieved in the combined therapy group than in IFN-α mono-therapy group at week 48 (P<0.05).Two factors were independently associated with HBeAg seroconversion:baseline HBeAg level <2.215 log10 index/mL and △HBeAg (.decline in HBeAg from baseline) >0.175 log10 at week 12.In conclusion,interferon-α plus ETV therapy can accelerate HBsAg decline as compared with interferon-α mono-therapy in CHB patients with lower baseline HBsAg levels,and the combination therapy was superior to IFN-α mono-therapy in increasing the rate of HBeAg seroconversion.Baseline HBeAg and △HBeAg at week 12 can independently predict HBeAg seroconversion in patients subject to interferon-based therapy for 48 weeks.
