Methods 86 patients with Ⅱ degree burns from July 2014 to July 2016 in our hospital were divided into the control group and the experimental group by lottery method with 43 cases in each group. The control group was treated with silver sulfadiazine, the experimental group was treated with Kang Shuling gel, the two groups of clinical curative efficacy, inflammatory factors, visual analogue scale (VAS), wound healing rate and wound healing time, wound infection rate and adverse drug reactions were compared. Results After treatment, the total effective rate of the experimental group was 95.34% higher than that of the control group 72.09%, the difference was statistically significant (P<0.05). The tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) levels of the experimental group was lower than the control group, the difference was statistically significant (P<0.05). The VAS of the experimental group was lower than the control group, the difference was statistically significant (P<0.05).The wound healing rate of the experimental group was higher than that of the control group on the seventh day and the fourteenth day, and the wound healing time was better than that of the control group, the difference was statistically significant (P<0.05). The wound infection rate of the experimental group was lower than that of the control group (P<0.05). There was no significant difference in adverse drug reactions between the two groups. Conclusion The curative effect of Kang Shuling gel on the treatment of Ⅱ degree burns patients worthy of affirmation, could reduce serum inflammatory factors level.

It has been demonstrated that astrocyte elevated gene 1 ( AEG-1 ) can promote tumor initia-tion and progression .Over expression of AEG -1 is correlated with tumor angiogenesis ,metastasis and chemother-apy resistance of tumor cells of different origins .The present article is a review on the mechanism of AEG -1 me-diated drug resistance .Studies have shown that AEG -1 participates in carcinogenesis through Ha -ras,myc,NF-κB and PI3K/Akt signalling pathways .AEG-1 can also promote autophagy through activating AMP Kinase . Other researchers demonstrate that AEG -1 promotes MDR1 protein translation by up-regulating MDR1 mRNA expression ,and thus increases polyribosome .It is testified that AEG-1 can influence drug susceptibility and ex-pression of MDR gene as a RNA binding protein .Multiple functions of AEG -1 in drug resistance in multiple cancers demonstrate that AEG -1 can be used as a novel target for antitumor drugs .

In this study, the rapid resolution liquid chromatography-quadrupole time-of-flight mass spectrometry (RRLC-QTOF/MS) was used to profile the metabolites of urine samples from chronic heart failure (CHF) patients and healthy controls to find the differential metabolites which could provide the scientific evidence to explain the pathogenesis of the disease and supply a better therapy plan.Urine samples from 15 CHF patients (age (62.27±3.14) years) and 15 healthy controls (age (65.41±4.63) years) were analyzed by RRLC-QTOF/MS.After processing the data, the multivariate statistical analysis (principal component analysis, PCA) was performed to find the potential biomarkers.Result showed that urine samples of CHF patients were successfully distinguished from those of healthy controls.Two significantly differentially expressed metabolites, uridine and alanyltryptophan, were found and identified as potential biomarkers.The result showed that the LC-MS based metabolomics approach had good performance to identify potential biomarkers, and the disorder of uracil metabolism and Tryptophan metabolism may play an important role in the mechanism of CHF.

Objective To investigate the characteristics of post-transplantation diabetes mellitus and analyze its risk factors. Methods Extensive survey was carried out to understand the characteristics of post-transplantation diabetes mellitus in patients who received kidney grafting from February 1984 to December 2006. Results Three hundred forty-four post-transplantatian diabetes mellitus patients from 1872 ones after kidney grafting were found from February 1984 to December 2006. The prevalence of new onset post-transplant diabetes mellitus and impaired fasting glucose in kidney allograft recipients were 18. 4% and 12. 7% respectively, being significantly higher than that in general population and other inpatients. The options of immunosuppressants were significantly associated with the prevalence of post-transplantation diabetes mellitus. By multivariate logistic regression analysis, the baseline characteristics of the post transplantation diabetes mellitus patients were significantly associated with increased age(OR: 1. 309, P = 0. 049), elevated level of the triglyceride (OR: 1. 311, P = 0. 005), treatment with taerolimus (FK506) (OR: 1. 522, P = 0. 008), and large dose of intravenous pulsed prednisolane(OR: 1. 239, P = 0. 011), as compared with patients without post-transplantation diabetes mellitus. Besides, the number of patients with at least one acute rejection episode was significantly greater in the post-transplantation diabetic patients. Mycophenolate mofetil (OR: 0. 716, P = 0. 028) and diltiazem (OR: 0. 737, P =0. 015) were associated with lower risk of post-transplantation diabetes mellitus. Conclusions High prevalence of abnormal glucose metabolism in renal allograft recipients during hospitalization was observed. Many risk factors contributed to the development of post transplantation diabetes mellitus.
