Objective To observe the effects of kaempferol on melanin synthesis, proliferation, and apoptosis of human epidermal melanocytes. Methods Human epidermal melanocyte suspension was prepared from male prepuce samples under 20 years old, and the applied dose of kaempferol and H2O2 was determined by CCK-8 method after culture. We took melanocytes and divided them into 10 µmol/L kaempferol group and negative control group; 10 µmol/L kaempferol was added to the 10 µmol/L kaempferol group, and the same volume of culture medium was added to the negative control group. The effect of kaempferol on melanin synthesis of human epidermal melanocytes was observed by NaOH lysis method (expressed by melanin synthesis) . The melanocytes were divided into the control group, kaempferol group, H2O2 group, and kaempferol+H2O2 group： the melanocytes in the control group were cultured for 48 h with melanocytes, and the melano‐ cytes in the kaempferol group were cultured for 48 h with 10 µ mol/L kaempferol, the melanocytes in the H2O2 group were cultured for 48 h with 0. 8 mmol/L H2O2, and the melanocytes in the Kaempferol+H2O2 group were first treated with 10 µmol/L kaempferol for 24 h, and then were cultured for 24 h with 0. 8 mmol/L H2O2. CCK-8 method was used to observe the effect of kaempferol on melanocyte proliferation (expressed by cell proliferation rate) ; the effect of kaempferol on the apoptosis of melanocytes was observed by annexinV/PI double staining method (expressed by the apoptosis rate) . Re⁃ sults The amount of melanin synthesis in the negative control group and 10 µmol/L kaempferol group was 100. 33 ± 0. 68 and 162. 97 ± 3. 34, respectively, with statistically significant difference between the two groups (P<0. 05) . The cell proliferation rates of the control group, kaempferol group, H2O2 group and kaempferol+H2O2 group were 100. 61%±1. 71%, 110. 27%±5. 83%, 51. 49%±2. 35% and 74. 96%±0. 53%, respectively, with statistically significant difference between groups (all P<0. 05) . The apoptosis rates of the control group, kaempferol group, H2O2 group and kaempferol+H2O2 group were 4. 30%±0. 72%, 3. 80%±1. 21%, 25. 93%±2. 23%, and 9. 73%±2. 39%, respectively, and the apoptosis rate of the H2O2 group was higher than those of the other groups (all P<0. 05) ; but there was no significant difference in the apoptosis among the the control group, kaempferol group and kaempferol+H2O2 group (all P>0. 05) . Conclusions Kaempferol (10 µmol/L) can promote melanin synthesis of human epidermal melanocytes. Kaempferol pretreatment can promote the proliferation of melanocytes stimulated by H2O2 and inhibit their apoptosis. [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to have a broader and deeper understanding of the regulatory factors of capsaicinnoid biosynthesis, and provide molecular basis for biotechnology breeding of pepper. [Method] The transcriptome of fruits in rapid growth stage and green mature stage from two pepper materials with different spicy degrees, '754-3-1-1-1' and 'Yujiao 5', were sequenced. The gene differential expression was analyzed by using the software cufflinks, and was verified by RT-PCR. The difference expression genes were obtained by comparing the transcriptome of two materials during two development stages, and GO enrichment analysis of the differential expression genes were carried out. [Result] A total of 139, 1903, 5550 and 3220 genes were differentially expressed in the pairwise comparisons of L754LS_vs_L754KS, YJ5LS_vs_YJ5KS, L754KS_vs_YJ5KS and L754 LS_vs_YJ5LS. There were 2667 (48%) unique differentially expressed genes in rapid growth stage and 871 (27%) in green maturity stage. In addition, a total of 18 CapCyc model genes were identified from four pairwise comparisons. Among them, PAL, CCoAOMT, CCR and other structural genes in capsaicin synthesis pathway were expressed more than 3 times differently in different samples. Moreover, 3 6 MYB and 4 ERF family transcription factors that may be involved in capsaicinnoid synthesis were identified. [Conclusion] Capsaicinnoid content was more affected by the expression level of genes in the early stage of fruit development. PAL and other structural genes may have the role of regulating the biosynthesis of capsaicinnoid. The study provides more candidate genes for future studies on capsaicinnoid biosynthesis regulatory network. [ABSTRACT FROM AUTHOR]

Objective: To study the effect of flunarizine combined with nerve growth factor(NGF) on NIHSS in patients with cerebral hemorrhage, ADL score and volume of hematoma. Methods: 98 cases of cerebral hemorrhage admitted to our hospital from September 2015 to October 2016 were selected as the study subjects, and divided into 2 groups by random number method, 49 cases in each group. Patients in the control group received conventional basic treatment, and patients in the study group received oral sibiline combined with intramuscular injection of NGF on the basis of this treatment. Compare two groups of patients with total effective rate of treatment, at the same time comparative hematoma, edema zone volume, neural function defect scale(NIHSS) scores, daily life ability scale(ADL)score, neurogenic nutrition factor(BDNF), monocyte chemotactic protein 1(MCP 1), neuron specific enolization enzyme(NSE) level changes and adverse reactions occur. Results: After treatment, the total effective rate between the two groups was significantly different(P<0.05). Before treatment, there were no significant differences in hematoma volume and edema zone volume between the study group and the control group. After treatment, the volume of hematoma and edema zone in the study group and the control group decreased with time, and the difference was significant(P<0.05). Before treatment, there were no significant differences in NIHSS and ADL scores between the study group and the control group. After treatment, the NIHSS of the study group and the control group decreased over time, and the ADL score of the study group was higher than that of the control group, and the difference was significant(P<0.05). Before treatment, there were no significant differences in BDNF, MCP-1 and NSE between the study group and the control group. After treatment,MCP-1 and NSE of the study group and control group decreased with time, and both of the study group were lower than the control group, while BDNF increased with time, and the study group was higher than the control group, the difference was significant(P<0.05).There was no significant difference in ADR between the two groups (P>0.05). Conclusion: The effect of sibilin combined with NGF in patients with intracerebral hemorrhage is reliable, which can significantly reduce the secondary injury, and the treatment is safe and worthy of clinical promotion.

Objective: To study the clinical efficacy of continuous positive-pressure ventilation in treatment of obstructive sleep apnea syndrome (OSAHS) complicated atrial fibrillation. Methods: A total of 60 patients with OSAHS complicated atrial fibrillation, who were admitted to Wuhan Third Hospital from January 2013 to January 2014, were selected and randomly divided into experiment group (n=30) and control group (n=30). The control group was treated with conventional therapy, on the basis of which the experiment group was added continuous positive-pressure ventilation. The duration of treatment of two groups was 1 year. The heart rate (HR), oxygen saturation (SPO2), left ventricular ejection fraction (LVEF), brain natriuretic peptide (BNP) in the two groups before and after treatment were analyzed. The cardioversion rate and recurrence rate of atrial fibrillation, and the adverse reactions in the two groups were compared. Results: HR, SPO2, LVEF and BNP in the experiment group after treatment were significantly better than those in the control group, the differences were statistically significant (P<0.05). Cardioversion rate of atrial fibrillation in the experiment group after treatment was significantly higher than that in the control group, and the recurrence rate of atrial fibrillation was significantly lower than that in the control group, the differences were all statistically significant (P<0.05). However, there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusions: Continuous positive-pressure ventilation has a good efficacy in the treatment of patients with OSAHS complicated atrial fibrillation, which is helpful in improving the heart function, increasing cardioversion rate and cutting down the recurrence rate of atrial fibrillation.
