Vitamin D has a wide range of biochemical effects. Insufficiency/ deficiency of vitamin D increases the risk of insulin resistance by ways of inflammation,adipocytokines,oxidative stress and mitochondria function,it could lead to metabolic disorder of glucose and lipid,which closely relates to the incidence and development of obesity and metabolic syndrome on children. This paper presents the relationship between vitamin D with obesity and metabolic syndrome on children,states the possible mechanisms of regulation of glucose/ lipid metabolism and insulin resistance by vitamin D.

Objective To study the role of glutamate receptor subtypes in nucleus tractus solitarius(NTS)in cardiac-somatic motor reflex (CMR)induced by intrapericardial administration of capsaicin,and to clarify the modulation mechanism of NTS to cardiac nociceptoion.Methods 60 SD rats were randomly divided into ibotenic (IBO)group, glutamate group, MK-801 group, MCGP group, MK-801 + MCPG group and DNQX group. The NTS microinjected with 130 mmol·L-1 IBO 100 nL,100,200,500 mmol·L-1 L-glutamate 100 nL,NMDA receptor antagonist 40 and 60 mmol · L-1 MK-801 100 nL, metabotropic glutamate receptors antagonist 25 and 50 mmol·L-1 MCPG 100 nL,25 mmol· L-1 MCPG 50 nL plus 40 mmol· L-1 MK-801 50 nL,non-NMDA receptor antagonist 20 and 50 mmol·L-1 DNQX 100 nL,respectively.The changes of CMR of the rats in various groups were observed.Results Compared with control group,the CMR of the rats in IBO group was decreased (P<0.05);the CMR was increased as the concentration increased in glutamate group(P<0.05);the CMR in MK-801 and MCPG groups were decreased (P<0.05);the CMR in MK-801+MCPG group was decreased (P<0.05);the CMR in DXQX group had no changes (P>0.05).Conclusion NTS play an facilictory role in cardiac nociception,and the NMDA receptors and mGluRs receptors mediate this facilitory modulation.

Objective To establish a method to measure Angiotensin Converting Enzyme activity in serum by MECC. Method Mixture of serum and substrate Hip-His-Leu had been incubated for 120 min at 37℃, substrate Hip-His-Leu was digested into two parts, Hip and His-Leu. The reaction was ended by 0. 1 mmol/L HC1 , the production was analyzed by MECC directly to detecte content of Hip in production, and calculated ACE activity. Running buffer was 20 mmol/L pH 9. 0 boric acid-borate buffer (including SDS 50 mmol/L) , capillary column was 75?m i. d.?37 cm, injection was 3s by press, voltage was 16 kV, running time was 7. 5 min, detected by UV detector at 200 nm, tempreture was 20℃. Result The within-run and between-run CV was 2. 7% and 5. 2%. The detection limits of ACE activity was 0. 2 IU/L ( singal/noise = 3). The ACE activity and absorption was linearly related from 2. 4 to 72 IU/L. The mean value of ACE was 5. 2-21. 9 IU/L (x?1. 96 s) in 50 normals. Conclusion It was a one of rapid, precise methods for determination of ACE activity in serum.

Objective To explore the role of metabotropic glutamate receptors (mGluRs)group Ⅲ and its subtypes mGluR7 and mGluR8 in nucleus tractus solitarius(NTS)in cardiac-somatic motor reflex (CMR),and to clarify the modulation role of mGluR Ⅲ and its subtypes in NTS in cardiac nociceptoion.Methods 40 SD rats were randomly divided into L-AP4 group,microinjection of mGluRs Ⅲ agonist L-AP4 0.1,1.0,10.0 or 20.0 nmol in NTS;AMN082 group,microinjection of mGluR7 agonist AMN082 1,2 or 4 nmol;DCPG group,microinjection of mGluR8 agonist DCPG 4, 6 or 8 nmol;MSOP group, microinjection of mGluR Ⅲ antagonist MSOP 20 or 100 nmol,20 nmol MSOP+410 nmol L-AP,20 nmol MSOP+2 nmol AMN082,20 nmol MSOP+6 nmol DCPG. The changes of CMR of the rats in various groups were observed.Results Compared with control,the CMR in L-AP4 and AMN082 groups was decreased (P<0.05);the CMR in DCPG group was increased (P<0.05);the CMR in MSOP group after injection of 20 nmol MSOP had no change (P>0.05);the CMR in MSOP group after injection of 100 nmol MSOP was increased (P<0.05);the CMR in MSOP group after injection of 20 nmol MSOP followed L-AP4 or AMNO82 had no change (P>0.05).Conclusion The group Ⅲ mGluRs in the NTS play an inhibitory role in cardiac nociception, and mGluR7 has anti-nociceptive effects while mGluR8 has pro-nociceptive effects.

OBJECTIVE:To provide reference for rational application of cephalosporins in the clinic. METHODS:The applica-tion of cephalosporins antibiotics in our hospital during 2010-2014 was analyzed dynamically in respects of consumption sum, DDD,DDC,DDDs,etc. RESULTS:During 2010-2014,the proportion of total consumption sum of antibiotics in total consump-tion sum kept below 30%,and decreased year by year,decreasing from 27.35% in 2010 to 14.70% in 2014. Among antibiotics, the consumption sum and DDDs of cephalosporins were the highest;consumption sum decreased year by year,decreasing from 44.50% in 2010 to 30.49% in 2014;DDDs increased year by year,increasing from 11.00×104 in 2012 to 14.22×104 in 2014. The consumption sum and DDDs of second generation cephalosporins were the highest. The consumption sum of cefotiam ranked the first place;DDDs of cefprozi ranked the first place during 2010-2011,while cefotiam ranked the first place during 2012-2014. DDC of cefpirome was the highest during 2010-2011,and that of cefamandole was the highest during 2012-2014,indicating it was expensive. The serial number ratio of cefprozi and cefuroxim was always >1 during those years,which indicated it was cheap and used frequently;that of most drugs were close to 1. CONCLUSIONS:The application of cephalosporins in our hospital tend to be rational,but the propaganda and supervision of rational use of antibiotics should be further strengthened.

Population control acculturation,which transforms population from heteronomy to self-discipline by imposing internal and external influences on humans,is an inevitable choice for current population control in China.To validly implement population control acculturation,various approaches of reproduction control are needed,mainly including contraception,artificial abortion and sterilization.A series of ethical issues are closely related to the above reproduction control approaches.
