OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

OBJECTIVE: To explore the hydrolysis kinetics of capilliposide B and capilliposide C under different temperatures and pH values, and identify the hydrolysis products. METHODS: The LC-B and LC-C were quantified by HPLC, then the hydrolysis process was deduced. Samples were taken to investigate the stability of LC-C and LC-B at different time points under the conditions of 30, 50, 70℃, and pH 8.0, 9.0, 10.0, 11.0, respectively. The hydrolysis products were identified by mass spectrometry and nuclear magnetic resonance spectroscopy. RESULTS: The hydrolysis reaction rates of LC-B and LC-C obeyed first-order kinetics under different pH values and temperatures. And they were related to hydrolysis temperature and pH: at the same temperature, the higher the pH, the faster the hydrolysis rate; at the same pH, the higher the temperature, the faster the hydrolysis rate. The hydrolysis product was capilliposide A. CONCLUSION: The study provided an effective method for the preparation of LC-A.

AIM: To explore the relationship between the expression of caspase-2 and caspase-3 and the apoptosis in retinal ischemia/reperfusion (I/R) injury of rats, as well as the therapeutic effects of brain derived neurotrophic factor (BDNF)on the ischemic and reperfused retina.METHODS: This experiment was conducted at the laboratory of Affiliated Hospital of Qingdao University Medical College from February 2007 to July 2007. The models of retinal ischemia/reperfusion injury were made by transiently elevating intraocular pressure. A total of 28 rats were divided into Normal and Operative Groups. Operative group was divided into six subgroups. In each subgroup there were four rats. The left eyes of rats were used for I/R and the right eyes were used for intravitreal injection of brain-derived neurotrophic factor (BDNF) as treatment group. After reperfusion we divided our subgroups according to the reperfusion time as 1, 6, 12, 24, 48, 72 hours. The retinal ganglion cell number was counted by using optic microscope(BX-51,Olympus). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and the expression of caspase-2,caspase-3 was studied by enzyme linked immunosorbent assay (ELISA) and strept avidin-biotin complex (SABC)immunohistochemistry.RESULTS: No positive apoptotic cells were observed in the normal rats' retinae, but there were a significant number of positive apoptosis cells in 6-24 hours after transient ischemia followed by a decrease at 48 hours. The number of apoptotic cells reached a maximum at 24 hours after ischemia .The expression of caspase-2 gradually increased as early as at 6 hours, reached a peak at 24 hours, then decreased between 48 and 72 hours. Similarly, caspase-3 has the same rule with caspsae-2 in the time courses of expression in retinal tissues.BDNF administered before reperfusion inhibited the expression of apoptosis and ameliorated the retinal tissue damage. It also decreased caspase-2 and caspase-3 expression in ischemic/reperfused retina.CONCLUSION: Retinal ischemia-reperfusion can induce apoptosis of cells in the retina. BDNF rescues retinal ganglion cells (RGCs) from retinal ischemia/reperfusion injury through down-regulation of cell apoptosis and caspase-2 and caspase-3 expression. BDNF have a neuroprotective effect on retina.

OBJECTIVETo analyze the relationship between the pulse pressure (PP) and atherosclerotic renal artery stenosis (ARAS) in middle-age and eldery paients with hyperensio, so as to provide the basis for the diagnosis and treatment of ARAS.

METHODSWe tetro spectively analyzed the data of 257 patients with hypertension undergoing renal arteriography at General Hospital of PLA between 2009 and 2014. Their mean age was (64.09 +/- 7.81) years. According the results of arteriography, they were divided into two groups: ARAS group (n = 145), and non-ARAS group (n = 112). Their PP and multinomial clinical indexes with ARAS were statistically analyzed.

RESULTSSingle factor correlation and Logisitic analysis showed that age, PP, serum creatinine (SCr) levels, and new onset of hypertension after 50 years of age were strongly positively related to ARAS. The age and PP and SCr was a team of continuous variable.

CONCLUSIONPP was the first new risk factor of ARAS in middile-aged and elderly patients with hypertension. It is suggested that PP may be a early predictive indicator and a new therapeutic target for ARAS.

Objective To investigate the Lymphocyte-specific protein-tyrosine kinase(Lck)gene ex- pression in the renal tubule epithelial cells(TECs)of lupus nephritis,and the effect of interlenkin-2(IL-2) stimulation on its expression.Methods Proximal TECs derived from 6 weeks old spontaneous systemic lupus erythematosus(SLE)BXSB mice were exposed to IL-2(100 U/ml),the expression of Lck mRNA and protein was examined by reverse transcription-polymerase chain reaction(RT-PCR)and immunoblotting respectively. The difference of Lck gene expression before and after IL-2 stimulation was investigated.The expression of Lck protein in TECs of renal tissues of BXSB mice and human with lupus nephritis was observed through im- munohistochemistry.Results The expression of Lck mRNA and protein was very low in cultured TECs of 6 weeks old BXSB mice,but increased sharply after IL-2 stimulation(P

0.05).Compared with control group,significant decrease in positive group was found in the interval from first evacuation of HM to resolution of serum ?-hCG level,(83?18) days versus(126?31)days(P0.05).Conclusions Once HM is diagnosed,evacuation should be performed as soon as possible,the later the evacuation begins,the higher the risks of lung metastasis and chemotherapy are.It is not necessary to worry about lung metastasis before evacuation of HM,the outcome of post- chemotherapy is very good.

Objective To explore the relationship between free fatty acid(FFA)composition and other glucose and lipid metabolic parameters in patients with metabolic syndrome(MS)in community. Methods Serum FFA profile was measured with gas chromatography and mass spectrometry in 158 patients with varied metabolic syndrome components(MSC),including 61 with MS and 97 at high-risk for MS,and 43 control subjects,with diagnostic criteria by the International Diabetes Federation(IDF).Results Patients with MS had higher parameters of polyunsaturated fatty acid(PUFA)and n6PUFA,as compared to the patients at high risk and normal subjects(P0.05). Among the high-risk group,those with diabetes had increased linoleic acid,n6PUFA and total fatty acid (TFA),and decreased saturated fatty acid(SFA)/TFA,as compared to those without diabetes(P
