Inferring Postmortem Submersion Interval in Rats Found in Water Based on Vitreous Humor Metabolites / 法医学杂志

OBJECTIVES@#The metabolomics technique of LC-MS/MS combined with data analysis was used to detect changes and differences in metabolic profiles in the vitreous humor of early rat carcasses found in water, and to explore the feasibility of its use for early postmortem submersion interval (PMSI) estimation and the cause of death determination.@*METHODS@#The experimental model was established in natural lake water with 100 SD rats were randomly divided into a drowning group (n=50) and a postmortem (CO2 suffocation) immediately submersion group (n=50). Vitreous humor was extracted from 10 rats in each group at 0, 6, 12, 18 and 24 h postmortem for metabolomics analyses, of which 8 were used as the training set to build the model, and 2 were used as test set. PCA and PLS multivariate statistical analysis were performed to explore the differences in metabolic profiles among PMSI and causes of death in the training set samples. Then random forest (RF) algorithm was used to screen several biomarkers to establish a model.@*RESULTS@#PCA and PLS analysis showed that the metabolic profiles had time regularity, but no differences were found among different causes of death. Thirteen small molecule biomarkers with good temporal correlation were selected by RF algorithm. A simple PMSI estimation model was constructed based on this indicator set, and the data of the test samples showed the mean absolute error (MAE) of the model was 0.847 h.@*CONCLUSIONS@#The 13 metabolic markers screened in the vitreous humor of rat corpses in water had good correlations with the early PMSI. The simplified PMSI estimation model constructed by RF can be used to estimate the PMSI. Additionally, the metabolic profiles of vitreous humor cannot be used for early identification of cause of death in water carcasses.

Protopine inhibits the growth of hepatocellular carcinoma through a mitochondrially mediated apoptosis pathway / 药学学报

Hepatocellular carcinoma (HCC) is a serious threat for human health, the incidence of HCC in China accounts for more than 50% worldwide. There is an urgent need to develop novel anticancer agents for the treatment of HCC patients. Here we characterized the inhibitory effect and the molecular mechanism of protopine on HCC cancer cells. The results of a CCK-8 assay indicated that protopine displays anticancer activities on HCC cells. Flow cytometry and JC-1 staining confirmed that treatment with protopine decreased the mitochondrial membrane potential and induced apoptosis in HCC cells. Western blot analysis showed that protopine was able to increase protein expression in the mitochondrial apoptotic pathway; the level of cytochrome C, apoptotic protease activating factor-1 (Apaf-1), Bax, cleaved-poly ADP-ribose polymerase (cleaved-PARP), cleaved-caspase-3, and cleaved-caspase-9 were increased while the expression of Bcl-2 was suppressed significantly. An in vivo study revealed that protopine significantly suppressed the growth of tumors in nude mice bearing HepG2 cells. Administration of protopine intraperitoneally at a concentration of 50 mg·kg-1 inhibited tumor growth by 72.46%. Animal experiments were carried out according to the Regulation of the Animal Ethics Committee of Southwest Medical University. This study provides preliminary evidence that there is potential to develop protopine as a lead compound for the treatment of HCC.

Progress on the measurement of corneal biomechanical properties / 国际眼科杂志(Guoji Yanke Zazhi)

Cornea is the major refractive components of the eye. As a viscoelastic tissue, cornea exhibits complicated biomechanical properties: non - linear elasticity, anisotropy and viscoelasticity. The biomechanical properties play an important role in keeping the normal structureand function. Changes in biomechanical properties are always earlier than the clinical symptoms. So quantitative measurement of the biomechanical properties benefits the early diagnosis and treatment of diseases. Different methods to measure the biomechanical properties of cornea were reviewed in detail, including classic ex vivo destructive tests, commercially available in vivo measuring methods and other emerging methods with the potential for clinical application but not validated for in vivo measurement. The operating principles, advantages as well as limitations of these methods were also described.

Study of effect of Humifuse Euphorbia Herb on alleviating insulin resistance in type 2 diabetic model KK-Ay mice / 中国中药杂志

[To explore the effect of Humifuse Euphorbia Herb ( HEH) on alleviating insulin resistance in type 2 diabetic KK-Ay mice. Totally 40 KK-Ay mice fed with high-fat diet were divided into four groups: the metformin group, the model group, the HEH low-dose group and the HEH high-dose group, and orally administrated with metformin hydrochloride (250 mg x kg(-1)), distilled water, humifuse euphorbia herb 1 g x kg(-1) and 2 g x kg(-1). Besides, C57BL/6J mice with ordinary feed were taken as the normal control group and orally administrated with equal distilled water. The oral administration for the five groups lasted for eight weeks. Before and after the experiment, weight, fasting glucose and insulin tolerance were determined. The morphological changes in pancreas were observed through hematoxylin-eosin (HE) staining on pancreatic tissue sections. The serum insulin, TNF-α, IL-6, adiponectin (ADPN) and leptin (LEP) were detected by ELISA. The results showed that HEH could reduce weight and fasting glucose in KK-Ay mice, alleviate hyperinsulinemia, reduce blood glucose-time AUC, increase 30-min blood glucose decline rate, relieve insulin resistance, significantly ameliorate the pathomorphological changes in pancreas in each group, decrease serum TNF-α, IL-6 and leptin levels in KK-Ay mice and rise serum ADPN level. This study proved that humifuse euphorbia herb can ameliorate the insulin resistance in KK-Ay mice, and its mechanism may be related to the effect on inflammatory factors and adipocytokines.
