The management of teaching,the foundation of teaching team,the selection of teaching materials and reformation of teaching mode are the key points that affect the teaching quality directly.

Objective To compare the early renal function recovery after kidney transplant from donation after cardiac death (DCD) and brain death (DBD).Methods The Medline (1950-2011),Embase and Cochrane library database were searched and supplemented by review of conference proceedings and publication bibliographies.All original single institution studies reporting outcomes for DCD and DBD kidney transplant recipients were considered.Odds ratios (OR) and 95％ confidence intervals (CI) based on random effects models were calculated.Results Nine publications,all cohort studies,involving 2049 DCD and 5498 DBD recipients,were included.DCD recipients had 7.24 times increased odds of DGF (OR=7.24,95％ CI =3.86-13.58),and 4.97 times increased odds of PNF (95％ CI =3.77-6.55).Conclusion DCD renal transplantation is associated with higher risks of DGF and PNF.

Objective To reveal the effect of fasting insuline(FINS) and insuline resistance(IR) in the process of benign prostatic hyperplasia(BPH). Methods One hundred and seventeen outpatients( ≥60 ys)with BPH from geriatric department were enrolled into the study. The patients were divided into groups according to their FINS and insulin resistance index (HOMA-IR). The indices of BPH, including volume of prostate ( PV ),prostate specific antigen( PSA ), international prostate symptom score (IPSS), course of BPH were analyzed in both groups. Results The PV ( [ 56. 46 ± 26. 88 ] ml vs [ 44. 84 ± 17.66 ] ml, P = 0. 017 ) and the course ( [ 18. 00 ± 6. 91 ] years vs [ 13.93 ± 7. 74 ] years, P = 0. 031 ) were significantly greater in BPH combined hyperinsulinemias(HINS) group than the BPH with normal FINS group;but we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. The PV( [54. 17 ± 25.38 ] ml vs [42. 26 ±14. 15]ml,P =0. 004)and the course([ 16.58 ±7. 65] years vs [13.49 ±7. 59] years,P = 0. 036) were also significantly greater in BPH combined insuline resistance gruop than the insulin sensitivity group, again we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. Conclusion FINS and IR are risk factors of progressed BPH and can promote the progress of BPH.

Objective To study the effects of melatonin on the expression of endothelin-1 (ET-1) and endothelial nitricoxide synthase (eNOS) in renal cortex of insulin-resistant (IR) rats. Methods Insulin-resistant rat model was established with 6-8 week ages Sprague-Dawwley (SD) rats by high-glucose diet (70% calories from glucose) for 6 weeks. IR rats models were divided into control normal group (CN, n=10), IR group (n=10) and melatonin group (MEL, n=10). Rats in MEL were affused melatonin 10mg/(kg·d) (4PM) for further 6 weeks. The protein and mRNA in rats' renal cortex of each group were assayed by immunohistochemistry and RT-PCR. Results Arterial blood pressure (ABP) and serum triglyceride (TG), free fatty acid (FFA), malondialdehyde (MDA), insulin (Ins) and homeostasis model analysis insulin resistance (HOMA-IR) in MEL were lower than that in IR (all P＜0.01). Serum high-density lipoprotein (HDL-c) and superoxide dismutese (SOD) were higher in MEL than that in IR (all P＜0.01). HE staining showed that the structure of renal cortex in MEL is approximately normal. The levels of ET-1 protein and mRNA in renal cortex of MEL rats were lower than that in IR group. The levels of eNOS protein and mRNA of renal cortex in MEL group were higher than that in IR group (all P＜0.05). Conclusion At the early stage of IR, melatonin application can ameliorate the imbalance between ET-1 and eNOS and protect the angio-endothelial function of renal cortex in high-glucose induced IR rats.

Objective To study normal flora components of conjunctiva, explore the relationship between normal flora and ocu- lar bacterial infections.Methods The data of 1 198 bacterial cultures of conjunctiva in non-infectious cataract patients were re- viewed and compared with the results of 985 specimens of conjunctivitis, keratitis and endophthalmitis from January 2000 to December 2004.Results Positive culture of conjunctiva in non-infectious cataract patients was 628 in 1 198 specimens (52.4%).These bacteria including gram-positive cocci and gram-neganve bacilli constituted the normal flora of conjunctiva. Staphylococcus epidermidis was the predominant bacteria (51.1%, 341/667) and its prevalence increased during this 5-year period.S.epidermidis and S.aureus were also the most frequently isolated pathogens in specimens of conjunctivitis, keratitis and endophthalmitis.The correlation was statistically significant between the positive rate in normal eye and conjunctivitis or keratitis in terms of these two species, but not statistically significant between normal eye and endophthalmitis.The resistance rate of normal flora of conjunctiva to ampicillin, amikacin, tobramycin, ciprofloxacin, and ofloxacin increased year by year. The resistance rate to gentamicin and the combination of two drugs decreased.The changing resistant pattern was similar in pa- tients with eye infection.Conclusions There is a close relationship between the normal flora S.aureus and S.epidermidis of conjunctiva and the bacterial infection of ocular surface, but no significant correlation between normal flora and the pathogen of endophthalmitis.

An extracellar fibrinolytic strain was isolated from fermented shrimp paste. In addition to general physiological and biochemical properties, the strain was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain had high similarity with AY601723 and AB195282, suggesting that the strain is a subspecies of Bacillus sp. It was named as Bacillus sp. nov. SK006 by CCTCC. The medium composition and fermentation conditions for fibrinolytic enzyme production were also optimized in the research.

OBJECTIVE:To investigate the compatible stability of Voriconazole for injection after mixed with Fructose injec-tion or Invert sugar injection. METHODS:Referring to package inserts,Voriconazole for injection 200 mg was dissolved with Wa-ter for injection to 20 mL,and then combined with Fructose injection 250 mL and Invert sugar injection 250 mL,respectively. At room temperature,the appearance of mixtures were observed 0,1,2,3,4,5 h after mixing,and pH value and the number of in-soluble particles were determined;the content of voriconazole was determined by HPLC. RESULTS:Under above condition,the appearance and pH value of mixtures had no significant change within 5 h;the number of particles ≥10 μm and ≥25 μm were all in line with the standard of Chinese Pharmacopoeia (2015 edition);the relative content of voriconazole was decreasing (95.28%-100%),but it changed within ±5%(RSD<2%,n=6). CONCLUSIONS:Voriconazole for injection could keep stable within 5 h after mixed with Fructose injection or Invert sugar injection.

Oxytocin ( OT ) is a cyclic neuropeptide containing nine amino acids residues, in addition to the traditional roles of uterine contraction and lactation, it also plays important roles in the central nervous system and other peripheral organs, such as improving schizophrenia, autism - related psychiatric and psy-chological symptoms. Oxytocin exhibits its physiological func-tions by binding to its receptor (oxytocin receptor,OTR). Cur-
rently researchers are manipulating OT system by developing new OTR ligand ( agonists and antagonists ) , hoping to prevent and treat OTR related diseases. This paper reviews the latest devel-opment of OTR agonists, antagonists and its physiological roles in central nerve system and peripheral organs.
