Objective: To study the effect of flavonoids from seed residues of Hippophae rhamnoides L.( FSH) and Hippophae rhamnoides L. oil(HRO)on serum lipid in female rats with obesity. Methods Female aged rats with obesity were given FSH and HRO by oral administration for 6 w. Serum triglyceride(TG) and cholesterol(TC) were determined every 2 w. The serum free fatty acid (FFA), high-density lipoprotein cholesterol (HDL-C),body weight and Lee’s index were measured after 6 w. Results: Serum TG and FFA level decreased significantly in rats given FSH. At the same time, FSH could inhibit the increase in body weight and Lee’s index. HRO could regulate the lipid metabolism and decrease serum TG level significantly in female aged rats with obesity. Conclusion: Both FSH and HRO can improve lipid metabolism in female aged rats with obesity.

Background and purpose:Cervical cancer remains the second leading cause of death in gynecologic malignancies partially because of resistance to chemotherapy. Bufalin, a component of the traditional Chinese medicine Chansu, has been widely used in cancer treatment in China. This study aimed to investigate the effects of bufalin on inhibiting the proliferation of ME180 and C33A and explore its possible mechanism.Methods:The cytostatic effects of bufalin on ME180 and C33A cells were evaluated by CCK8 assay (cell counting kit-8). Glucose levels in ME180 and C33A cells were measured using glucose assay kit. Then the alterations of GLUT1 (glucose transporter 1) and HK2 (hexokinase 2) gene expression were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The expressions of proto-oncogene C-MYC and HIF1α (hypoxia-inducible factor 1α) were determined by Western blot.Results:According to the results of CCK-8, bufalin can significantly inhibit the proliferation of carcinoma cells ME180 and C33A (P=0.027,P=0.018). Test on glycometabolism indicated that glucose uptake in cells treated with bufalin decreased (P=0.034,P=0.036). Results from real-time PCR showed that the expression of glycometabolism related indicators GLUT1 (P=0.019) and HK2 (P=0.016) levels were signiifcantly down-regulated in bufalin treated group. Western blot showed that the expression of C-MYC and HIF1αin cells with bufalin treatment was down-regulated markedly.Conclusion:Bufalin can inhibit the proliferation of the cervical carcinoma cells ME180 and C33A through inhibition of their glucose metabolism.

Objective To evaluate the protective effect of astragaloside Ⅳ against ultraviolet B (UVB)-induced photodamage to human HaCaT keratinocytes,and to investigate its mechanisms.Methods Culturedimmortalized human HaCaT keratinocytes were divided into four groups:blank control group receiving untreated,UVB group irradiated with 50 mJ/cm2 UVB,astragaloside Ⅳ group treated with astragaloside Ⅳ,UVB + astragalosideⅣ group treated with astragaloside Ⅳ for 24 hours before and after 50 mJ/cm2 of UVB radiation.The concentration ofastragaloside Ⅳ ranged from 10 to 200 mg/L in cell proliferation assay,and according to the results of proliferationassay,20 mg/L was determined as the optimal concentration in the other assays.At 24 hours after UVB radiation,cellcounting kit-8 (CCK8) assay was performed to evaluate cellular proliferative activity,flow cytometry to determineintracellular reactive oxygen species (ROS) levels,and Western blot to measure the expression levels of p53,p38,matrix metalloproteinase-9 (MMP-9) and high mobility group Al (HMGA-1) protein in HaCaT cells.ResultsCompared with the control group,astragaloside Ⅳ at 10 and 20 mg/L had no inhibitory effect (F =1.32,P ＞ 0.05),while astragaloside Ⅳ at 50,100 and 200 mg/L showed significantly inhibitory effect (F =20.20,P ＜ 0.05),on theproliferation of HaCaT cells.In addition,cellular proliferative activity in the UVB group was significantly lower thanthat in the control group (F =99.00,P ＜ 0.01).Compared with the UVB group,cellular proliferative activityincreased to different degrees in HaCaT cells treated with both UVB and astragaloside Ⅳ of 10-200 mg/L (F =19.08,P ＜ 0.01),with the strongest increase observed in those treated with UVB and astragaloside Ⅳ of 20 mg/L.Further experiments revealed reduced intracellular ROS levels in the UVB + astragaloside Ⅳ (20 mg/L) groupcompared with the UVB group (t =21.12,P ＜ 0.01).Western blot assay showed that the expression levels of p53,p38,MMP-9 and HMGA-1 protein were significantly higher in the UVB group than in the control group (all P ＜0.01),but significantly lower in the UVB + astragaloside Ⅳ (20 mg/L) group than in the UVB group (all P ＜ 0.01).Conclusion Astragaloside Ⅳ can effectively protect keratinocytes from UVB-induced photodamage.

Objective Psoriasis vulgaris (PV) is easy to prone to recur and hard to cure and little research has been done on combined treatment on PV.The article was to study the clinical effects of total glucosides of paeony capsules (TGP) combined with acitretin and compound flumethasone on PV as well as the peripheral blood cytokine levels.Methods 126 patients with PV who visited our hospital from October 2015 to January 2017 were randomly divided into combined treatment group (63 cases) and control group (63 cases).Both groups were treated with oral acitretin and topical compound flumethasone, what's more, the compound flumethasone group received oral TGP treatment, 8 weeks for a course.The clinical therapeutic effects were evaluated by the levels of peripheral blood IL-17, IL-18, IL-23, TNF-α level, PASI score and percentage of total skin lesions before and after the treatment.Results After the treatment, the concentration of IL-17, IL-18, IL-23 significantly decreased(P<0.05), which was significantly less in combined treatment group compared with control group (IL-17 [61.18±8.91] vs [78.64±7.85], IL-18 [68.56±17.95] vs [79.49±18.64], IL-23 [70.13±12.16] vs [91.18±16.89] pg/ML)(P<0.05).Moreover, the TNF-α level, the PASI score and the percentage of total skin lesions significantly decreased in both groups after treatment(P<0.05), which was significantly less in combined treatment group compared with control group (TNF-α level [14.47±7.53] vs [23.49±8.12]ng/L, PASI score [4.09±1.29] vs [7.29±5.13], the percentage of total skin lesions [6.17±4.59]% vs [8.09±5.18]%) (P<0.05).Conclusion TGP combined with acitretin and compound flumethasone can significantly enhance the clinical therapeutic effects and effectively regulate the levels of the IL-17, IL-18, IL-23 and TNF-α level, which results in treating psoriasis vulgaris.

Aim To investigate the effect of baicalin on cell proliferation and cell migration in human skin SCC A431 cell line. Methods The A431 cells were incu-
bated with 50 mg·L-1 baicalin. The protein level of cofilin-1 was assayed by Western blot. Cofilin-1 specific siRNA fragment was designed , synthesized and trans-
fected into A431 cells. The proliferative activity and migration ability of cells were assessed by CCK8 assay and scratch wound healing assay separately. ResultsWestern blot results showed that baicalin treatment in-hibited the cofilin-1 protein expression to 49.3% com-pared with the control group. Single baicalin treatment and cofilin-1 silencing could drease the A431 cell growth and migration. And cofilin-1 silencing signifi-
cantly enhanced the efficacy of baicalin. Conclusions Baicalin could significantly inhibit the tumor cell's growth and migration in the A431 cell line. And cofi-lin-1 might become the potential target gene to enhance the effect of anticancer drugs.

Objective:To investigate the relationship of antinuclear antibody (ANA) status with clinical features and malignancy risk in adult patients with dermatomyositis.Methods:A retrospective analysis was performed to analyze clinical data from 101 inpatients with dermatomyositis in Department of Dermatology, the First Affiliated Hospital of Soochow University from April 2008 to April 2018. These patients were divided into ANA-positive group and ANA-negative group, and differences in myopathy and malignancy risks as well as other clinical features were analyzed between the 2 groups. A 2-year follow-up was undertaken among 92 patients. Chi-square test was used to analyze and compare clinical features between the 2 groups, and a multivariate regression model was used to analyze the relationship of ANA status with amyopathic dermatomyositis and malignancies.Results:Among the 101 patients with dermatomyositis, there were 42 males and 59 females, aged 55.13 ± 14.63 years; 14 patients had amyopathic dermatomyositis, 6 patients had hypomyopathic dermatomyositis, and 81 patients had myopathic dermatomyositis; 42 (41.58%) cases were positive for ANA, and 59 (58.41%) were negative for ANA. Compared with the ANA-negative group, the ANA-positive group showed significantly decreased incidence of cervical erythema (33.33% vs. 59.32%, P=0.010) and shawl sign (14.28% vs. 35.59%, P=0.017) . Twenty-eight (27.72%) patients with dermatomyositis were complicated by malignancies. Malignancies were found in 5 (11.9%) of ANA-positive patients, and in 23 (38.98%) of ANA-negative patients. Univariate analysis showed that ANA-negative patients with dermatomyositis had a higher risk of malignancies compared with ANA-positive patients with dermatomyositis, with an odds ratio of 7.52 (95% CI: 1.62-13.78, P=0.003) . In the multivariate regression model, the absence of ANA ( OR=4.34, 95% CI: 1.37-13.72, P=0.012) and cervical erythema ( OR=3.27, 95% CI: 1.20-8.91, P=0.020) were associated with high incidence of malignancies, while the absence of ANA was not significantly correlated with the occurrence of amyopathic dermatomyositis ( OR=0.99, 95% CI: 0.32-2.99, P=0.980) . Conclusions:ANA-negative adult dermatomyositis patients with cervical erythema had an increased risk of malignancies. Thus, close follow-up and regular tumor screening are necessary in these patients.

Objective To investigate the role of nicorandil pretreatment on protecting myocardium after coronary microembolization (CME) and on the PDCD4/NF-κB/TNF-α signaling pathway in miniature pigs. Methods Fifteen Bama miniature pigs were randomly(random number) divided into the sham operation group (sham group), microembolization group (CME group) and CME plus nicorandil group, with 5 pigs in each group. The CME model was constructed by injecting polyethylene microspheres via microcatheter into the left anterior descending artery, and pigs in the sham group were injected with the same amount of saline. Pigs in the CME plus nicorandil group were injected intravenously with nicorandil (150 μg/kg) via ear vein 30 min before CME. Cardiac function indexes were measured using cardiac ultrasonography. The expression of PDCD4 and TNF-α mRNA in myocardium were detected by fluorescence quantitative PCR, and the protein expression of PDCD4 and TNF-α in myocardium were detected by Western blotting. NF-κB activation was evaluated by electrophoretic mobility shift assay. Results (1) Cardiac function was significantly lower and the level of serum cTnI was significantly higher in the CME group compared with the sham group. CME reduced myocardial systolic dysfunction and left ventricular dilatation. The CME plus nicorandil group showed improved CME-induced cardiac function and reduced serum cTnI level when compared with the CME Group (P < 0.05). (2) Compared with the CME group, the CME plus nicorandil group showed lower PDCD4 and TNF-α expression and NF-κB activity as well as improved cardiac function (P < 0.05). Conclusions The pretreatment of nicorandil effectively reduced the myocardial damage caused by CME, mainly through inhibiting the PDCD4/NF-κB/TNF-α pathway in cardiomyocytes.
