OBJECTIVETo observe the effect of Bushen Huatan Recipe (BHR) on the Akt signal pathway in polycystic ovarian syndrome (PCOS) model rats with insulin resistance (IR).

METHODSFifty Wistar female PCOS rats were randomly and equally divided into 5 groups, i.e., the control group, the model group, the low dose BHR group (5.406 g/kg), the medium dose BHR group (10.812 g/kg), and the high dose BHR group (21.624 g/kg), 10 in each group. Levels of fasting blood glucose (FBG) and insulin were detected to calculate homeostasis model assessment of insulin resistance (HOMA-IR). The expression of insulin receptor substrate 1 (IRS-1), glycogen synthetase kinase-3beta (GSK-3beta), glucose transporter 4 (GLUT-4), and peroxisome proliferator activated receptor (PPAR-gamma) mRNA were detected by RT-PCR. The expression of insulin signal transduction molecular kinase B (Akt) was detected by Western blot.

RESULTSCompared with the control group, HOMA-IR and the mRNA expression of PPAR-gamma mRNA significantly increased, the mRNA expression of GSK-3beta, GLUT-4, and IRS-1, protein expression of Akt and p-Akt significantly decreased in the model group (P < 0.05). Compared with the model group, HOMA-IR significantly decreased, the mRNA expression of GSK-3beta, GLUT-4, IRS-1, and Akt protein significantly increased in the high dose BHR group (P < 0.05, P < 0.01). The mRNA expression of p-Akt protein increased more obviously (P < 0.05, P < 0.01). mRNA expression of GSK- 3beta and GLUT-4 significantly increased (P < 0.05), while the mRNA expression of PPAR-gamma significantly decreased in the low and middle BHR groups (P < 0.05). The expression of p-Akt significantly increased in the low dose BHR group (P < 0.05).

CONCLUSIONSIR and abnormal insulin signal pathway existed in PCOS model rats. BHR could improve IR of PCOS rats, which was correlated with regulating protein expression of insulin signal transduction molecules.

The definition of rehabilitation should reflect the connotation and extension of rehabilitation medicine system,moreover,special attention should be paid to the process of translation,applications and promotion due to its derivation from Latin.The fourth edition of rehabilitation medicine textbook which published by People's Medical Publishing House described the definition of rehabilitation inaccurately,although integrated the foreign authority definitions.The definition of ‘ re-learning’has been described by the textbook without considering logical sequence,which caused difficulty in explaining and comprehending between teachers and students in class.Besides,application of another term of rehabilitation medicine in the textbook is imprudence.

Objective To summarize the recent progress in pathogenetic,diagnostic and therapeutic researches on the intestinal barrier dysfunction(IBD) of severe acute pancreatitis(SAP).Methods The advancement of IBD in SAP,which was published recently at home and abroad,was collected and reviewed.Results The pathogenesis of IBD in patients with SAP was complex.Ischemia-reperfusion injury,endotoxin,inflammatory mediators and gastrointestinal hormone played an important role in the process of IBD.There were many ways to detect IBD,and the ratio of lactulose and mannitol,plasma diamine oxidase were relatively ideal markers.Medical therapies,such as treatment of SAP and maintaining the perfusion of intestines,were essential to cure IBD.On this basis,the propulsives,nutritional support and traditional Chinese drugs should be administered reasonably.Conclusions IBD is a sophisticated process of pathophysiology.In recent years,abundant of animal experiments and clinical researches have provided new clue for prevention and cure of IBD,but further researches are still needed on the mechanism of the cells and molecules implicated.

ObjectiveTo evaluate the effect of Yuxingchangzhi Decoction on level of norepinephrine (NE) and 5-hydroxyptamin (5-HT) in serum of patients with post-stroke depression. Methods76 patients with post-stroke depression were treated with Yuxingchangzhi Decoction or placebo for 4 weeks. Before and after treatment, all the patients were evaluated with the Hamilton Rating Scale for Depression (HAMD),while the level of NE and 5-HT in serum of patients were measured.ResultsThe total score of HAMD of the patients of Yuxingchangzhi Decoction group was significantly different before and after treatment (P<0.01),while that of the placebo group was not significantly different (P>0.05). The NE and 5-HT level in serum of patients of the Yuxingchangzhi Decoction group were significantly different before and after treatment (P<0.01),but that of the placebo group was not significantly different (P>0.05). ConclusionYuxingchangzhi decoction can raise NE,5-HT level in patients with post-stroke depression and alleviate symptoms of depression significantly.

This study investigated the protective effect of ATP on skeletal muscle satellite cells damaged by H2O2 in neonatal rats and the possible mechanism. The skeletal muscle satellite cells were randomly divided into four groups: normal group, model group (cells treated with 0.1 mmol/L H2O2 for 50 s), protection group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h, and then with 0.1 mmol/L H2O2 for 50 s), proliferation group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h). MTT assay, FITC+PI+DAPI fluorescent staining, Giemsa staining and immunofluorescence were performed to examine cell viability and apoptosis, and apoptosis-related proteins. The results showed that the survival rate of skeletal muscle satellite cells was decreased and the apoptosis rate was increased after H2O2 treatment (P<0.01). Different doses of ATP had different effects on skeletal muscle satellite cells damaged by H2O2: the survival rate of muscle satellite cells treated with ATP at 4, 2, or 1 mmol/L was increased. The protective effect was most profound on cells treated with 2 mmol/L ATP. Immunofluorescence showed that ATP could increase the number of Bcl-2-positive cells (P<0.01) and decrease the number of the Bax-positive cells (P<0.01). It was concluded that ATP could protect skeletal muscle satellite cells against H2O2 damage in neonatal rats, which may be attributed to the up-regulation of the expression of Bcl-2 and down-regulation of Bax, resulting in the suppression of apoptosis.
