Soluble ST2 (sST2) is a decoy receptor of IL-33 in blood.sST2and ST2L (receptor on cell membrane) seem to be markedly induced in mechanically overloaded cardiac myocytes,especially the expression of sST2.A large number of sST2 bind IL-33 thus subtracting IL-33 from the interaction with ST2L,potentially attenuating the cardioprotective effects of IL-33/ST2L pathway.Recently,sST2 has emerged as a novel for heart failure biomarker.Though sST2 was a less robust marker for the diagnosis of heart failure than NT-proBNP,it has been implicated in the prognostication of patients with acute dyspnea,acute or chronic heart failure and myocardial infarction,with particular value for mid-and long-term prognosis.However,further studies are needed in order to better point out the evidence for a routine use of sST2 evaluation in patients suffering from cardiovascular diseases.

Objective To investigate the effect of high uric acid(HUA) on insulin sensitivity (IS) in 3T3-L1 adipocytes and its mechanism. Methods 3T3-L1 adipocytes were pretreated with HUA with or without NAC,and then stimulated by insulin. The cell viability of 3T3-L1 adipocytes was detected by CCK-8 assay. The glucose consumption was measured by glucose oxidase method. The levels of phospho-IRS-1,phospho-Akt and GluT4 protein were tested by western blot. Results HUA could inhibit insulin-induced glucose consumption,phosphorylation of Akt (Thr308),dephosphorylation of IRS-1 (Ser307) and the GluT4 protein expression (P<0.05). All the above could be blocked by NAC(P<0.05). Conclusion HUA can inhibit inulin stimulated IRS-1/Akt signaling and GluT4 expression,and thus induced insulin resistance in 3T3-L1 adipocytes.

Objective To investigate the histological changes of normal human skin after fixed irradiation with multiple-pulse fractional Er:YAG laser.Methods After hair removal,the upper arms of 7 healthy volunteers were consecutively irradiated with multiple-pulse fractional Er:YAG laser.Tissue samples were resected from the irradiated skin at 1,24,48,72 hours,on day 5,7,15,and 30 after the irradiation.Hematoxylin and eosin(HE)staining and Masson staining were performed to observe the histological changes and collagen proliferation respectively.Immunohistochemical staining was used to detect the expression of heat shock protein(HSP)70 and 47.Results The consecutive irradiation with multi-pulse fractional Er:YAG laser generated an array of tapering microscopic treatment zones(MTZs)of gasification and ablation in the upper arm skin.After the irradiation,inflammation developed in the microscopic lesions with the epithelization of epidermal cells within 7 days; local dermal collagen was renewed and remodelled during the 7th to 30th day.HSP70 expression peaked as early as 48 hours after the treatment and maintained until the 7th day,while the high expression of HSP47 persisted from the 15th to 30th day after irradiation.Conclusion The fixed,multiplepulse and fractional Er:YAG laser irradiation can reach the deep dermis,and induce the local proliferation of dermal collagen.

ObjectiveTo observe β cell function in newly diagnosed diabetic patients with ketosis before and in remission period and evaluate its classification and predictive value.MethodsA total of 206 patients newly diagnosed as diabetic ketosis who had been treated with intensive insulin therapy in our hospital and entered in the honeymoon after the withdraw of insulin therapy were followed for 36 months from onset of diabetes.They were divided into two groups of type 1 and type2 diabetes ( group A and B),according to the dependence or independence on insulin treatment. The β cell function of the two groups before and in remission period was compared by oral glucose tolerance test (OGTF).β cell function was measured with the AUC of insulin and C-peptide and homeostatic model assessment β-cell function (HOMA-β),while homeostatic model assessment insulin resistant (HOMA-IR) for insulin resistant.The duration of the honeymoon and the change of insulin and C-peptide curve before and in honeymoon were also observed.ResultsThe AUC of insulin and C-peptide,the HOMA-β and the HOMA-IR before and after the intensive insulin treatment were lower in group A than that in group B [ before the insulin treatment:(10.18 ±2.36)mIU · h · L-1 vs (20.28 ±6.89)mIU · h · L-1,(1.56 ±0.53) μg · h · L-1 vs (3.75 ±0.67) μg · h · L-1,3.68 ± 1.08 vs 18.20 ±6.59,1.22 ±0.49 vs 3.06 ± 1.54,respectively;after the insulin treatment:(29.86 ± 8.65 ) mIU · h · L-1 vs (93.35 ± 19.42 ) mIU · h · L-1,( 3.99 ± 0.79 )μg · h · L-1 vs ( 12.54 ±3.83) μg · h · L-1,8.50 ±2.46 vs 56.17 ± 19.42,0.63 ±0.56 vs 1.42 ±0.78,respectively ].The duration of the honeymoon in group A was significantly shorter than in group B [ (7.9 ±5.2) months vs (20.9 ± 9.9 ) months ].In oral glucose insulin and C-peptide release test,the peak of insulin and C-peptide releasing curve in group A was brought forward by a half to 1 hour after intensive treatment while delayed in group B by 1 or 2 hours.The releasing peak of insulin and C-peptide in group A was less than two folds of the basic value,while four to ten fold of the basic value in group B.The positive ratio of glutamic acid decarboxylase antibody,insulin autoantibody and insular cellular antibody in group A and group B were 21.2％ vs 4.8％,18.1％ vs 3.3％,9.2％ vs 10.6％,respectively.ConclusionsOf all the patients newly diagnosed as diabetes ketosis who had entered into the honeymoon after intensive insulin therapy,91％ were type 2 diabetes.Inferior β cell function before insulin therapy,weaker remission after insulin therapy and shorter duration of remission period suggest the classification of type 1 diabetes.

Objective To establish the reference range of serum human serum insulin levels in our laboratory and investigate measurement stability, Methods The automated Architect i2000 chemiluminescence immunoassay, calibrator and quality control materials were used to measure concentration of serum insulin. Totally 413 cases of healthy adults were enrolled. The physiologic characteristics and the influence of laboratory markers on insulin levels were analyzed. Then the reference range in our laboratory was established. The thermal stability of insulin at different temperatures was investigated. Results Within-run imprecision and between-day imprecision of the automated Architect i2000 insulin assay were 1.67% and 2. 6%, which indicated that this system had good analytical performance. The subjects were classified into 4 groups according to age range ( 10 years). There was no significant difference among four age groups (the median is 5. 6, 5.2, 5.3 and 5. 7 mU/L) (X<'2> = 1. 929,P >0.05). However, the insulin levels were higher in female ( median = 5.7 mU/L) than male ( median = 5.0 mU/L) ( Z = 3.696, P < 0.01 ). The reference range was established based on the 2. 5 and 97.5 percentile values. The reference range of insulin for female was 2. 6-11.8 mU/L and 2. 3-11.6 mU/L for men, which differed from that of other insulin assay. Insulin had a positive correlation with BMI (r =0. 115 ,P =0. 019) and triglyeeride (r =0.143 ,P = 0. 004), and a negative correlation with high density lipoprotein (r = -0.179, P = 0.000). Insulin was stable at 25 ℃ for at least 4 hours or 4 ℃ for 24 hours or could be extended to at least 7 days when stored at -20 ℃. Conclusion Gender is an important physiologic characteristic which has an impact on human serum insuhn level. Insulin reference range should be established according to gender. Insulin immunoreactivity was not very stable at different temperatures.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.
