To establish HPLC specific chromatogram and its correlation with the protection effect of Shuanghuanglian on MDCK (Madin-Darby canine kidney) cell injury induced by influenza A virus( H1N1). Nine recipes of Shuanghuanglian based on the official prescription were prepared according to orthogonal test for HPLC analysis and MDCK cells protection experiment separately (cytopathic effect (CPE) method was used for observing the virus infectivity and MTT staining results were used as the determining indexes for drug concentration selection and analyzing cell viability). The results suggested that all the other Shuang-Huang-Lian recipes except recipe1 demonstrate protecting effect on MDCK cell injury induced by influenza A virus (P < 0.01, P < 0.001). Stepwise regression analysis was used for analyzing the relationships between HPLC fingerprint and the protecting effect of Shuanghuanglian on influenza A virus induced MDCK cell injury. Peak 2, 3, 6, 8 and 12 were found to be strongly related with anti-influenza A virus efficacy. Stepwise regression analysis of recipes data and efficacy data showed that Lonicerae Japonicae Flos and Forsythiae Fructus were positively associated with the protecting effect of cells injury. From HPLC fingerprints, we found that peak 2, 3, 12 were from Lonicerae Japonicae Flos and peak 6, 8 were from Forsythiae Fructus. Four peaks were identified through comparing the retention time between the standard and Shuanghuanglian recipes, and they were chlorogenicacid, cryptochlorogenic acid, forsythoside B and 3,4-dicaffeoylquinic acid respectively. Caffeic acid derivatives in Lonicerae Japonicae Flos and Forsythiae Fructus were found to be greatly correlated with anti-influenza A virus efficacy and maybe the substance basis of Shuanghuanglian.

To survey the serum uric acid (SUA) levels and associated risk factors of hyperuricemia among youth and middle-aged residents in Guangzhou.A total of 1420 subjects,aged from 20 to 60 years,receiving health check-up at our hospital in 2010 were enrolled.The total prevalence of hyperuricemia was 22.04％,32.01％ in males and 14.07％ in females.The average SUA was (388 ±78) μmol/L in males and (288 ± 63) μ mol/L in females.The prevalence of hyperuricemia in males was 30.11％ before 40 years of age and 33.81％ between 40 and 60 years of age.The average level of SUA in males was significantly higher than that of females.logistic regression analysis showed that BUN,body mass index (BMI) and hypertriglyceridemia were the independent risk factors of disease while HDL-C and gender (females) the protective factors.

Objective:To explore an effective treatment method for mycobacterial infection of multiple abscesses in the face and breast after autologous fat injection.Methods:Six patients with non-tuberculous mycobacterial infection after autologous fat injection in the face and chest were treated from June to September in 2018. All patients underwent preoperative ultrasound localization. The small incision was opened for debridement and the necrotic granular tissues were completely scraped. Vacuum aspiration therapy in the sinus was used to promote wound growth, in line with the standard anti-tuberculosis drug treatment.Results:All six patients in this group were being followed up for 10-14 months. The average follow-up time was 12 months. All the infected patients were recovered, and the appearance of the infected site was satisfied by the patients.Conclusions:Small incision debridement with vacuum aspiration therapy combined with a variety of anti-tuberculosis drugs can effectively treat non-tuberculous mycobacterial infection after autologous fat injection, and achieve good results.

An experiment was conducted using cultivated Glycyrrhiza uralensis in age of one year to study the effects of abscisic acid (ABA) on chemical components content and color of G. uralensis. By using different concentrations of ABA spraying on leaves, the change of the chemical component content was analyzed within 45 d after ABA stimulation, and the effects on quality were studied combined with colorimetric analysis data. It turned out that in some sense the content of glycyrrhizic acid and liquiritin had increased within 45 d, especially for liquiritin. After high concentrations of ABA (3.96 mg · L(-1)) stimulating, the content of glycyrrhizic acid rose 52% while liquiritin up 392% within 30 d. Then they both showed a decline in the content of glycyrrhizic acid and liquiritin on 45 d. Color index values of a* and b* were all significantly higher than that of the control group within 45 d, which meant the color of powders turned toward red and yellow. The conclusion was that ABA (3.96 mg · L(-1)) stimulating could not only improve the quality in the traditional sense through the color of G. uralensis, but also in the modern sense by improving the content of glycyrrhizic acid and liquiritin.

α-Hederagenin (H), derived from Hedera nepalensis var.sinensis, is a pentacyclic oleane-type triterpenoid that exhibits clear cytotoxicity to different tumor cell lines.In this study,a series of novel C-28 derivatives of hederagenin (H) were designed and synthesized in attempt to develop potent tumor resistance reverse activities agents. Previous research showed that H6 displayed robust reverse activity for paclitaxel resistance in KBV cells. Importantly, Co-treatment of paclitaxel with H6 significantly reduced the tumor weight to 42%. Pleasingly, H6 enhanced the efficacy of paclitaxel against KBV cancer cell-derived xenograft tumors in nude mice.Mechanism studies had found that H6 activated permeability glycoprotein(P-gp)ATPase,reduced intracellular ATP levels and inhibited efflux of P-gp substrates,thus enhancing the antitumor activity of paclitaxel on KBV cells.Molecular docking analysis of homology P-gp and H6 then conducted using the Surflex-Dock module.H6 showed a high binding affinity docking score with a total score of 5.4148,much higher than that of H(0.1414).The nov-el C-28 derivatives of H was synthesized from H6 via three-step reaction. The reversal activity of all synthesized H derivatives were tested using the MTT assay.The results showed that the derivatives of nitrogen groups at C-28 displayed same even potent activity than parent compound H6.In addition,its underlying mechanism of action and in vivo activity are in explore.

Objective To observe the impacts of different storage temperatures on the activities of adipose tissues and the extraction and proliferation of adipose-derived stem cells (ADSCs) situated in harvested fat.Methods Adipose tissues obtained by liposuctions in healthy females were kept in different temperature;all groups of adipose tissues were studied in context of the histomorphology and activity of GAPD as well as the extraction efficiency and proliferation of ADSCs.Results Adipose tissues cryopreserved at 4 ℃ within 24 hours could retain their activities effectively,but their activities would decrease rapidly if they preserved at room temperature.The efficiency of adipose tissues extracting stem cells and their proliferations were affected by storage temperatures and times.If adipose tissues were preserved at room temperature for over 1 hour,the extraction efficiency and proliferation of their ADSCs would be lower significantly.Conclusions Adipose tissues cryopreserved at 4 ℃ can effectively ensure their activities and their extraction efficiency and proliferation of ADSCs.It is important to preserve adipose tissues at low temperature after harvesting fat graft.
