OBJECTIVETo study the effect of eight specifications of Cervi Cornu Pantotrichum on the osteoporosis of ovariectomized rats and grade the eight different specifications of Cervi Cornu Pantotrichum.

METHODTotally 100 SD female rats were divided randomly into 10 groups, namely the normal group, the model group and eight Cervi Cornu Pantotrichum groups of different specifications. Their bilateral ovaries were excised to reproduce the osteoporosis model. Meanwhile, the rats were given the eight different specifications of Cervi Cornu Pantotrichum for consecutively 12 weeks. Subsequently, the effects of the different specifications of Cervi Cornu Pantotrichum on bone mineral density and serum biochemical indicators of rats were observed. A clustering analysis was made for the eight specifications of Cervi Cornu Pantotrichum, with the serum content of ALP, BMP-2 and BGP as influencing factors.

RESULTAfter 12 weeks, the eight different specifications of Cervi Cornu Pantotrichum could significantly improve ALP, BMP-2, BGP in serum and bone mineral density of ovariectomized rats. And the cluster analysis showed similar results to the quality classification of traditional commercial herbs Cervi Cornu Pantotrichum.

CONCLUSIONDifferent specifications of Cervi Cornu Pantotrichum can antagonize the osteoporosis of ovariectomized rats, and their effects are related to the quality of commercial herbs.

Objective To investigate the expression of microRNA (miRNA) in placenta tissue, explore the function of miRNA in pathogenesis of gestational diabetes mellitus (GDM). Methods Placenta tissue from pregnant women with GDM and normal controls were selected from January 2013 to January 2014. Expression of miRNAs were detected by sequencing technique and quantity real time PCR(qRT-PCR). Target genes of miRNA were analyzed by KEGG. Results 52 insulin signaling pathway related miRNAs including 47 up-regulated and 5 down-regulated were differentially expressed in GDM compared with normal control. Expression of placental hsa-miR-548am-5p and hsa-miR-95-5p were significantly increased , but hsa-miR-1246 was significantly lower (P <0.05) in GDM group than normal control; all the results were consistent with sequencing results. Key points of insulin signaling pathway could regulate expression of targets such as PI3K. Conclusion miRNA expression in GDM placenta was abnormal.A variety of exp ressions of miRNAs were involved in the pathogenesis of GDM by regulating insulin signaling pathway.

Objective To investigate Schistosoma japonicum infection on mice high-fat diet of insulin resistance. Methods 36 male C57 BL/6 J mice were randomly assigned into three equal groups: normal control group ( NC group) , high-fat diet group ( HF group) and high-fat diet with Schistosoma japonicum infected group ( HSJ group) . Specimen was collected 6 and 12 weeks after high-fat diet, separately. The levels of fasting blood glucose ( FBG) , fasting plasma insulin resistance index ( FINS) and insulin ( HOMA-IR) were detected. Interferon-γ( IFN-γ) ,in-terleukin-4 ( IL-4 ) and singal transductor and activator of transcription-4 ( STAT4 ) singal transductor and activator of transcription-6 (STAT6)were detected by ELISA and immunohistochemical method. Results The mice from HF group showed higher levels of HOMA-IR than those from NC groups by the end of 6 and 12 weeks after infection( P<0. 01 );the levels of HOMA-IR in mice from HSJ group were lower than NC group and HF group by the end of 12 weeks(P<0. 05);the levels of IL-4 in mice from HSJ group were higher than NC group and HSJ group by the end of 6 and 12 weeks after infection ( P<0. 05 ); the levels of STAT6 in mice from HSJ group were higher than HF group by the end of 12 weeks after infection ( P<0. 05 );the levels of STAT4 in mice from HF group were higher than NC group by the end of 6 and 12 weeks after infection. Conclusion Schistosome japonicum chronic infection may improve insulin resistance in obese mice with induced STAT6 protein expressed in liver tissue and secrete IL-4,providing new ideas for the prevention and treatment of diabetes.

Objective To investigate the association between chronotropic incompetence (CI)and motor ability in type 2 diabetic mellitus (T2DM) patients complicated with metabolic syndrome (MS).Methods One hundred and twenty patients with T2DM were enrolled in the study,including 66 cases with MS (MS group) and 54 without MS (non-MS group).The electrocardiographic exercise test was performed,the CI indexes including ratio of heart rate (rHR),heart rate reserve (HRR)were measured and the max metabolic equivalents(maxMETs) were calculated.Result The rHR(0.77 ±0.04 vs.0.81 ±0.06,t =3.41,P ＜ 0.05),HRR (0.62 ± 0.05 vs.0.70 ± 0.07,t =5.96,P ＜ 0.05) and maxMETs (8.8 ± 1.1 vs.9.7 ± 1.2,t =0.16,P ＜ 0.05) in patients of MS group all lower than those in non-MS group.The maxMETs were positively correlated with rHR (r =0.81,P ＜ 0.05) and HRR (r =0.78,P ＜ 0.05).Conclusion The results indicate that CI as well as maxMETs and rating of perceived exertion can be used as monitoring index in type 2 diabetic patients complicated with metabolic syndrome.

Objective The purpose of this study was to investigate the effect of a dietary modification intervention model applied by ward nurse on change of dietary behavior among patients with type 2 diabetes mellitus (T2DM).Methods A total of 80 participants were divided into intervention patients (n=40) and control subjects (n=40) by random number table.Except lecture-based diabetes educational which was applied for control subjects,a dietary modification intervention model was conducted in intervention patients for a period of two weeks.The intervention program consisted of evaluating an individual's stage of change after being provided dietary information regarding kind of food and portions,discussion with a role model,and keeping a food diary record.Body mass index (BMI),waist-hip ratio (WHR),fasting plasma glucose (FPG),postprandial 2-h plasma glucose (2hPG),glycosylated hemoglobin (HbAlc) and score of healthy eating behavior were measured at initial and six months later.Results Compared with control group,BMI,WHR,FPG,2hPG,HbA1c in intervention group were significantly decreased,P ＜ 0.01 or 0.05.After six months intervention,FPG,2hPG and HbA1c in both groups were significantly decreased compared with baseline levels,P＜ 0.01.Compared with control group,the scores of healthy eating behavior in intervention group were significantly decreased,P＜ 0.05.After six months intervention,the scores of healthy eating behavior in both groups were significantly elevated,P ＜ 0.01,compared with baseline levels.Conclusions This study yielded evidence for the benefits of using the dietary modification intervention model as a framework in healthy eating behavior among patients with T2DM.

This paper presents the results of an ultrustructural study of the hepatoma cell lines FSK 7901, FSK 7902 of long term cultures about 2 years more.The size of cell varies. Distribution of the cell is single or in epitheloid monolayer. Pseudopodial processes or microvilli cover the perimeter of certain hepatoma cells. In the monolayer, the microvilli exist where the neighboring plasmalemmae are in loose contact. When their contact is close, the neighboring plasmalemmae may be straight, wavelike or interdigitated. The nucleus and enlarged nucleoli are irregu- lar in shape. The deformity of nucleolonema is remarkable.Rough endoplasmic reticulum (RER) and mitochondria are much less in number in the cytoplasm, but the free ribosomes is very abundant. The shape of mitochondria and their cristae are irregular. The Golgi complex is often or less arranged around 10 in a group, situated near the nucleus. Typical coucentric body from RER or SER has not been observed. Annulate lamellae are easily found. A peculiar structure, primordial rough-surfaced endoplasmic reticulum (PRER) is seen.Juxta-nuclear acidophilic area consists of a group of Goigi complex or Golgi complex and mitochondria.

In 2015 , policy reforms on centralized drug purchasing system have been released one by one , and the quality of medicines has been highly valued .Centralized drug purchasing system distinguishes different qualities of drugs mainly through bidding grouping , in order to achieve “uality priority”.However , there are yet some existing problems in group bidding policy at present , such as lack of a unified hierarchy , no scientific indicators and so on , which inevitably weaken the leading role of centralized purchasing policy over the quality of medicines .This paper , focuses on the study of group bidding , and the existing main problems are found through the statistical analysis of rel-evant policies introduced in different provinces .Finally, it explores some optimization strategies for “Group Bidding”which is of paramount importance .
