To investigate the active compounds from on the heart and brain of mice at simulated high altitude.Fifty healthy male adult BALB/c mice were randomly divided into normal control group, hypoxic model group, acetazolamide group, petroleum ether extract of (PESI) group and octacosan group with 10 mice in each group. Acetazolamide group, PESI group and octacosan group were treated with acetazolamide PESI (200 mg/kg) or octacosan by single tail vein injection, respectively. Except normal control group, the mice were exposed to a simulated high altitude of for in an animal decompression chamber. After the mice were sacrificed by cervical dislocation, the heart and brain were histologically observed by HE staining; superoxide dismutase (SOD) activity, total anti-oxidant capacity (T-AOC) and the content of malondialdehyde (MDA) in plasma, heart and brain tissues were detected by WST-1 method, ABTS method and TBA method, respectively; lactic acid and lactate dehydrogenase (LDH) activity in plasma, heart and brain tissues were detected by colorimetric method and microwell plate method, respectively; ATP content and ATPase activity in heart and brain tissues were detected by colorimetric method. PESI and octacosane significantly attenuated the pathological damages of heart and brain tissue at simulated high altitude; increased SOD activity, T-AOC and LDH activity, and decreased the contents of MDA and lactic acid in plasma, heart and brain tissues; increased the content of ATP in heart and brain tissues; increased the activities of Na-K ATPase, Mg ATPase, Ca ATPase and Ca-Mg ATPase in myocardial tissue; and increased the activities of Mg ATPase, Ca-Mg ATPase in brain tissue. PESI and octacosan exert anti-hypoxic activity by improving the antioxidant capacity, reducing the free radical levels, promoting the anaerobic fermentation, and alleviating the energy deficiency and metabolic disorders caused by hypoxia in mice.

Objective: To analyze the genotypes, amino acid vatiations and molecular epidemiological characteristics of respiratory syncytial virus (RSV) infection in pediatric patients in Gansu province for the future research. Methods: A total of 4 556 respiratory tract specimens were colleted from pediatric patients under 10 years of age in five cities in Gansu from 2012 to 2017. These specimens were tested for RSV and its subtypes.The coding region of the RSV G gene was amplified using reverse transcription-polymerase chain reaction (RT-PCR) and sequenced for RSV positive specimens. Sequences were edited using DNA Star software. Sequence alignment and phylogenetic trees were built by MEGA 6.0 software. Results: Out of 4 556 specimens, 1 135 (24.91%) were positive for RSV, totally 216 G protein sequences were obtained. RSV A isolates were clustered into three genotypes: NA1、NA3 and ON1. The nucleotides and amino-acid homology was 84.9%-100% and 77.3%-100%, respectively. The nucleotides and amino-acid homology between this study and prototype long strain was 81.2%-83.3% and 74.1%-88.0%. RSV B isolates were clustered into only BA9 one genotypes. The nucleotides and amino-acid homology was 97.7%-100% and 95.8%-100%, respectively. The nucleotides and amino-acid homology between this study and prototype CH18537 strain was 84.9%-85.7% and 77.9%-80.1%. Conclusions The genetic characteristics and the amino-acid changes were analyzed systematically using data of RSV G gene collected from 2012 to 2017 in Gansu province in this study. These data were used for analyses of the etiology, control and prevention of RSV infection.

This article gave a detailed account of the practice and characteristics of medical support training in U.S. Navy hospital ship MERCY.We compared the details of medical support training in this ship with those in the Chinese Na-vy hospital ship Ark Peace.We offered suggestions as follows:①During the future medical support training on board, we should regard training procedures and medical techniques as equally important.②We should establish an examination and evaluation team for the medical staff during the training.③We should establish selection standards for significant missions and conduct routine evaluation of the medical staff aboard the hospital ship.

Objective To observe the effect of mifepristone (MIF) on the level of corticotropin releasing hormone (CRH),adrenocorticotropic hormone (ACTH),corticosterone (CORT),insulin (INS) and aldosterone (ALD) in plasma and expression of glucocorticoid receptor (GR) mRNA in hippocampus in type 2 diabetic rats and to discuss the effect and mechanism by which mifepristone improves hyperglycemia. Methods Type 2 diabetes mellitus model was induced by high-fat diet plus intragastric administration of low dose streptozotocin (30 mg·kg-1 ). Rats were randomly divided into normal control group,model control group,positive control (MET) (metformin hydrochloride 200 mg·kg-1 ·d-1 ) group,mifepristone low dose (MIF-L) (10 mg·kg-1 ·d-1 ),medium dose (MIF-M) (25 mg·kg-1 ·d-1 ) and high dose (MIF-H) (50 mg·kg-1 ·d-1 ) groups. The normal control group and model control group were given distilled water. Fasting blood glucose (FBG) was measured once a week. The rats were decapitated after five weeks. Organ index, corticotropin release hormone ( CRH), adrenocorticotropic hormone (ACTH),corticosterone(CORT),insulin(INS) and aldosterone(ALD) levels were measured. The expression of GR mRNA in hippocampus was measured by using real-time PCR. Results Compared with the normal control group, body weight was decreased significantly (P<0. 01),FBG was increased significantly (P<0. 01),organ index was increased significantly (P<0. 05), CRH,ACTH,CORT,INS and ALD were increased and the expression of GR mRNA in hippocampus was decreased (P<0. 01) in the model control group. Compared with model control group,body weight increased in MIF-M and MIF-H groups after administration for 14 days (P<0. 01). FBG was decreased in MIF-M group 1 to 4 weeks after administration,with significant difference (P<0. 05) at 4th week. The kidney index was decreased in MIF-M and MIF-H groups (P<0. 01,P<0. 05). CRH,ACTH and CORT were increased,ALD level was decreased in MIF-L group,CRH,ACTH,CORT and ALD were decreased,INS level was increased in MIF-M and MIF-H groups,without statistically significant differences (P>0. 05). Relative expression of GR mRNA was significantly increased in MIF-L,MIF-M and MIF-H groups (all P <0. 01). Conclusion Hyperglycemia in type 2 diabetic rats can be improved by MIF. The possible mechanism may be related to regulating the HPA axis through inhibiting GR.

Aim To investigate HPA axis change relation with glucose and lipid metabolism.Methods Wistar rats were injected intraperitoneally with STZ (30 mg·kg~(-1)) after fed with high lipid food for two months, then rats with blood glucose of over 15 mmol·L~(-1) were used in the experiment. Animals were divided into four groups: normal group, diabetic model group, treatment group (ROS 200 mg·kg~(-1) ·d~(-1) ig), and metformin group (200 mg·kg~(-1)·d~(-1) ig).Rats were decapitated after they had been administered ig for four weeks and were 24 hour urine collected.Plasma CRH, ACTH, corticosterone, hypothalamic CRH, ACTH of pituitary gland, 24 hour urinary corticosterone and plasma insulin were determined by ELISA and radio immunity kit respectively.Results In diabetic rat model induced by high lipid food and STZ, plasma and urinary glucose level and plasma TC, TG levels were increased, plasma HDL-C and hepatic glycogen content were reduced, which was synchronized with changes of higher pituitary ACTH, plasma and total 24 hour urine corticosterone excretion.Conclusion The disorder of glucose and lipid metabolism of model induced by high lipid food and low dose STZ may be linked to the change of HPA axis.The improvement of ROS on glucose and lipid metabolism in diabetic rats may be linked to the decrease of HPA axis activity.
