Obective To evaluate the effects of dihydrotestosterone (DHT) on the expression of sterol regulatory element-binding protein-1c (SREBP-1c) in human HaCaT keratinocytes.Methods HaCaT cells were cultured in vitro and classified into 4 groups,i.e.,control group receiving no treatment,DIIT group treated with 3 different concentrations (10,100,1000 nmol/L) of DHT,LY294002 plus DHT group treated with DHT of 100 nmol/L after 40-minute pretreatment with the PI3K inhibitor LY294002 of 50 μmol/L,PD98059 plus DHT group treated with DHT of 100 nmol/L after 40-minute pretreatment with the MEK inhibitor PD98059 of 50 μmol/L.After another 24-hour culture,real time PCR and Western blot were carried out to detect the expression of SREBP-1c mRNA and protein in HaCaT cells,respectively.Western blot was also performed to determine the phosphorylation levels of protein kinase B (AKT),extracellular signal-regulated kinase (ERK),p38 mitogen activated protein kinase and c-Jun N-terminal kinase (JNK) in the HaCaT cells.Results DHT could enhance the expression of SREBP-1c mRNA and protein in HaCaT cells in a concentration-dependent manner,and induce the phosphorylation of AKT and ERK,but not that of P38 or JNK.The expressions of SREBP-1c mRNA and protein were significantly decreased in HaCaT cells treated with LY294002 plus DHT (7.4780 ± 1.2638 vs.21.6170 ± 2.2759,t =9.406,P < 0.05; 0.7113 + 0.0313 vs.2.2577 + 0.0601,t =39.498,P < 0.05),but experienced no statistical changes in those treated with PD98059 and DHT(both P > 0.05),compared with those treated with DHT only.Conclusion DHT can induce the expression of SREBP-1c mRNA and protein in HaCaT cells,likely via the PI3K/AKT signaling pathway.

ObjectiveTo observe the effect of topical sulfotanshinone sodium(STS) on sebaceous hyperplasia in animal models. MethodsThe sebaceous gland spots of adult male Syrian hamster flank organ served as the animal model. Sulfotanshinone sodium(0.5%) was applied to sebaceous gland spots in the right flank organ thrice daily, while those in the left were treated with normal saline as control. Parameters were examinedbefore, 10 days, 20 days and 30 days after the beginning of the topical treatment. A vernier caliper was utilized to measure the size of sebaceous gland spots, hematoxylin and eosin(HE) staining to observe the structure of sebaceous glands, immunohistochemistry to determine the expression of proliferating cell nuclear antigen (PCNA) in sebaceous gland cells, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay to assess the apoptosis of sebaceous gland cells. ResultsAt the baseline, no significant difference was observed in the size of sebaceous gland spots or in the proliferation and apoptosis of sebaceous gland cells between the two sides of flank organ(all P > 0.05), with tightly arranged intact sebaceous glands. Compared with normal saline, sulfotanshinone sodium significantly reduced the size of sebaceous gland spots(P < 0.05). Sebaceous glands were loosely arranged with decreased quantity and volume and obviously atrophic on day 30 in the right flank organ of hamsters. A decrease was observed in the expression of PCNA in sulfotanshinone sodium treated sebaceous gland cells compared with those treated with normal saline(P < 0.01 ), which was more striking on day 10 and 20(both P < 0.005). Sulfotanshinone sodium also induced an enhancement of apoptosis in sebaceous gland cells (P < 0.01 ), which was more apparent on day 20 (P < 0.005 ), and the degree of apoptosis was higher in the central area than in the peripheral area of sebaceous glands. ConclusionSulfotanshinone sodium can reduce the size and alter the microstructure of sebaceous gland spots, and inhibit the hyperplasia of sebaceous glands.

OBJECTIVE: To study the antidepressant effects of total flavone of A( TFA) on post stroke depression ( PSD) in rats. METHODS: Middle cerebral artery occlusion ( MCAO) followed by isolation feed and irritable stimuli was used to induce PSD. Behaviours of rats were detected by open- field test . The effects of TFA on the indexes of hemorheology and brain homogenate lipid peroxidation were also tested. RESULTS: TFA could increase the crossing and rearing scores in open- field test, inhibit the elevation of whole blood viscosity as well as plasma viscosity at high- middle- low shear rates, increase the erythrocyte deformation, enhance the activities of Superoxide Dismutase ( SOD) and Glutathione Peroxidase ( GSH- Px) , and reduce Malondialdehyde ( MDA) content in brain homogenate in PSD in rats. CONCLUSIONS: TFA produces an antidepressant- like effect in PSD rats. This mechanism may be in association with attenuating hemorheological parameters and decreasing lipid peroxidative damage.

Objective To observe the influence of exterior-interior meridian acupoint selection on hippocampal cell apoptosis and c-Jun N-terminal kinase ( JNK) in ischemia-reperfusion injury rats, and to explore the possible protective mechanism for ischemia-reperfusion injury. Methods One hundred and twenty SD rats were randomly divided into sham-operation group (SH), model group (I/R), electroacupuncture (EA) group and JNK inhibitor SP600125 ( SP) group. The ischemia-reperfusion model was established by occlusion of middle cerebral artery with intraluminal thread. EA group was given EA on acupoints of Zusanli ( ST 36) , Sanyinjiao ( SP 6) , Chize ( LU 5) , Hegu ( LI 4) , once a day, based on the method of exterior-interior meridian acupoint selection. We observed the neurological behavioral changes by Longa neurological function standard, detected the activation of phosphorylated JNK ( p-JNK) by immunohistochemical method and examined the hippocampal apoptotic index by TUNEL method. Results The neurologic impairment scores of EA group and SP group were lower than I/R group (P<0.05) . Apoptotic index of I/R group was higher than SH group (P<0.01) and that of EA group and SP group was lower than I/R group (P <0.05) . The level of p-JNK in I/R group was higher than SH group ( P <0.01) and that of EA group and SP group was lower than I/R group ( P <0.05). Conclusion Exterior-interior meridian acupoint selection therapy has certain effect on alleviating neurologic impairment and reducing apoptosis in ischemia- reperfusion injury rats, and the mechanism might be associated with the inhibition of the activation of JNK signaling pathway.

Objective To investigate the risk factors for hemorrhagic transformation (HT) and poor outcomes in patients with acute ischemic stroke after mechanical thrombectomy.Methods The patients with acute ischemic stroke received mechanical thrombectomy were enrolled retrospectively.The demography,vascular risk factors and other clinical data of the patents were collected.The modified Rankin scale (mRS) was used to evaluate the clinical outcomes at day 90.Good outcome was defined as mRS score 0-2.The patients were divided into either a HT group or a non-HT group according to their HT conditions.Multivariate logistic regression analysis was used to identify the independent risk factors for HT and poor outcomes.Results A total of 48 patients with acute ischemic stroke received mechanical thrombectomy were enrolled,including 25 males (52.1%).Their mean age was 64.77± 9.14 years.The mean National Institutes of Health Stroke Scale (NIHSS) score was 17.70 ± 3.77.Twenty-two patients (45.8%) occured HT,of which 9 were symptomatic HT;24 (50.0%) had good outcomes.The proportion of males in the HT group was significantly lower than that in the non-HT goup (30.4%vs.72.0%;x2 =8.293,P =0.004),while the proportions in patients with diabetes (65.2% vs.36.0%;x2 =4.090,P =0.043) and atrial fibrillation (78.3% vs.44.0%;x2 =5.880,P =0.015),as well as the baseline fasting blood glucose level (8.514 ± 4.400 mmol/L vs.6.354 ± 1.472 mmol/L;t =2.319,P =0.025) were significantly higher than those in the non-HT group.Multivariate logistic regression analysis showed that the atrial fibrillation (odds ratio [OR] 6.136,95% confidence interval [CI] 1.617-23.291;P =0.042) was a risk factor for the occurrence of HT after mechanical thrombectomy.The proportion of diabetic patients (29.2% vs.70.8%;x2 =8.333,P=0.04) and baseline NIHSS score (16.050±4.865 vs.19.210±4.423);t=2.310,P=0.026) of the good outcome group were significantly lower than those of the poor outcome group,while the proportions of patients in atrial fibrillation (75.0% vs.45.8%;x2 =4.269,P =0.039),anterior circulation stroke (87.5% vs.62.5%;x2 =4.000,P =0.046) middle cerebral artery (75.0% vs.29.2%;x2 =10.113,P =0.006),vertebral basilar artery (37.5% vs.12.5%;x2 =10.113,P =0.006) occlusion and parenchymal hematoma (33.3% vs.4.1%;P=0.011) were significantly higher than the poor outcome group.Multivariate logistic regression analysis showed that diabetes (OR 5.898,95% CI 1.699-20.479;P=0.005),baseline NIHSS score (OR 1.167,95% CI 1.011-1.347;P =0.035),and parenchymal hematoma (OR 1.295,95% CI 1.099-1.875;P=0.028) were the independent risk factors for poor outcomes.Conclusions Atrial fibrillation is an independent predictor of HT risk in patients with acute ischemic stroke after mechanical thrombectomy.Diabetes mellitus,higher baseline NIHSS score,and concurrent brain parenchymal hematoma are the independent predictors of poor outcomes.Therefore,the risk of HT and adverse outcomes should be fully assessed before mechanical thrombectomy in patients with acute ischemic stroke.
