ObjectiveTo investigate the roles of 11 β-hydroxysteroid dehydrogenase type 1 ( 11 β-HSD1 )on hippocampus of rat with chronic unpredictable mild stress (CUMS).MethodsTwenty-four male SpragueDawley rats were randomly divided into control group and depressive model group. Chronic unpredictable mild stress (CUMS) was used to make up depressive animal model.Behavioral changes were recorded by body weight measuring,sucrose consumption test (SCT) and open field test (OFT),respectively.The mRNA transcription of 11β-HSD1 in hippocampus tissues of the rats were detected by real-time RT-PCR,and the protein expression of 11β-HSD1 were detected by western blot and immunofluorescence.ResultsBcforc starting CUMS protocol,the rats exhibited equivalent weight and sucrose consumption.Twenty-eight days after CUMS protocol,behavior parameters such as body weight,sucrose consumption,nunber of crossing,and number of rearing were significantly decreased in rats exposed to CUMS group compared with control group (P < 0.05,P < 0.01 ).Correspondingly,realtime RT-PCR assays showed the mRNA expression of 11 β-HSD1 in the hippocampus of CUMS group,which was (31 ±9) % lower than that of control group.Meanwhile,the protein expression of it in CUMS group was lower than that of control group (P < 0.05 ).Inmunofluorescence revealed that the number of positive 11 3-HSD1 cells was high (223 ± 13) in the control group,while the number was decreased prominently (92 ± 11 ) in the CUMS group (P < 0.01 ).ConclusionDepressive behavior of rats is induced and the expression of 11 β-HSD1 in the hippocampus is decreased prominently by CUMS,the mechanism of which is at least related to the low expression of 11β-HSD1 and disturbance of glucocorticoid metabolism caused by CUMS.

AlM: To find out the weaknesses of the cultivation of the Chinese ophthalmology physicians and the gap between Chinese and the international ophthalmology physicians, so that provide the advice on the future cultivation of the Chinese ophthalmology physicians.
METHODS: The passrate of the 2013 lCO examinations taken by worldwide examiners by common statistical methods was analyzed.
RESULTS:The results indicated that the test scores of Chinese candidates' were lower than that of the international average level, there was a obvious gap existed between Chinese and other countries' ophthalmology physicians. lt showed that Chinese candidates were not quite adaptable to this examination, basic science and clinical level needed to be improved.
CONCLUSlON:lt may shows that the effects on the mid-anaphase of our country's ophthalmology residency training are not so good, which area we should pay more attentions.

Objective To screen altered proteins of hippocampus in the stress-induced depression (STRID) rat model, and explore the potential molecular mechanism. Methods Twenty Sprague-Dawley rats were randomly divided into the control group and STRID group, 10 rats in each group. Chronic unpredictable mild stress (CUMS) methods including fasting for solids and liquids, electric foot-shock, reversing day and night, cold water swimming, cage tilt, scare stimulation and tail pinch were conducted on STRID rats with no repeats for 28 days to make up the depression animal model. The control group was normally fed during this period. After the stress stimulation, the hippocampus protein samples were used for two dimensional electrophoresis to screen the differentially expressed protein, and then mass spectrum identification and function analyze were conducted. Results Compared with the control group, 34 proteins were altered in STRID group. Among which, 18 were up-regulated, and 16 were down-regulated. The differentially expressed proteins mainly located in cytoplasm, mitochondrion, extracellular exosome and myelin sheath. The involved signaling pathways included metabolic pathway, oxidative phosphorylation pathway, and Alzheimer's disease, Parkinson's disease and Huntington's disease pathways. Conclusion The altered proteins and dysfunction of nerve signaling, and the excess of oxidative phosphorylation in hippocampus of STRID rats may be one of the pathogenesises.

Objective:To analyze the availability ofpediatricessential medicines in China, and to provide reference and suggestions for the further responses to the demand for pediatric medication in China. Methods :Using survey data collected from 19 provinces in China through the cooperation of the National Health Commission and our research group, the availability of pediatricessential medicines in China was analyzed from the perspectives of drug use and a-vailability with its influencing factors. Results :The survey results showed that the availability of pediatricessential medicines in China is generally low. The shortage in such medicines does not occur in individual regions, individual medical institutions or individual treatment areas, but it is still general in the surveyed parts of the country. The two fundamental reasons for the noticed shortage are :the research on special varieties for Children is expensive and the pricing mechanism of suitable varieties is inappropriate, which results in insufficient motivation for R&D Enterprises. Conclusions :This article suggests that the existing national pediatric medication support policies should be put in place as soon as possible, andbe further implemented for nationwide pediatric consumption. It is also recommended that health, drug supervision, bidding, pricing, medical insurance and other departments should work together to make more preferential policies to help enterprises develop special pediatric drugs to further promote the supply and respond to the demand of medicine for children in China.

Chinese Journal of Surgery 2008;46(20):1579-1582
OBJECTIVETo explore the relationship of apolipoprotein E (ApoE) genotype with hypertriglyceridemia-associated recurrent acute pancreatitis.
METHODSTaking the fasting serum triglyceride (TG) level > or = 2.3 mmol/L as hypertriglyceridemia, ApoE genotypes in 115 patients with hypertriglyceridemia-associated recurrent acute pancreatitis were assessed by polymerase chain reaction. According to the fasting serum TG level, all patients were divided into 3 groups: TG mild elevation group (2.3 mmol/L < or = TG < 5.5 mmol/L, Group A), TG moderate elevation group (5.5 mmol/L < or = TG < 11.3 mmol/L, Group B), and TG severe elevation group (TG > or = 11.3 mmol/L, Group C).
RESULTSGroup C had significantly fewer patients with biliary tract disease, improper diet and heavy alcohol consumption, and significantly more patients with passed history of moderate-severe hypertriglyceridemia than Group A and B (P < 0.05). The proportion of patients with E3/4, E3/2, E2/4 and E2/2 genotypes and gene frequency for epsilon 2 and epsilon 4 alleles are significantly higher in Group C than in Group A and B(P < 0.05). Group B had significantly more patients with E3/2 genotype and higher gene frequency for epsilon 2 allele than Group A (P < 0.05).
CONCLUSIONSApo epsilon 2 and epsilon 4 alleles are closely related to moderate-severe hypertriglyceridemia-associated recurrent acute pancreatitis.
