As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.

OBJECTIVE:To observe the efficacy and safety of domestic cefepime in the treatment of patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPD) complicated with respiratory failure. METHODS:A total of ninety-six patients with AECOPD complicated with respiratory failure were randomly assigned to receive cefepime 2.0 g bid iv gtt (Group A,n=48) or cefoperazone/sulbactam (Group B,n=48) at a dose of 2.0 g bid iv gtt for 7～14 day. RESULTS:The effective rate was 82% for Group A versus 62% for Group B(P0.05). CONCLUSION:The efficacy of cefepime is higher than that of cefoperazone/sulbactam in the treatment of patients with AECOPD complicated with respiratory failure,but both had good safety.

OBJECTIVE:To evaluate the cough-relieving and sputum-eliminating efficacy and safety of Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution.METHODS:By a randomized control study,a total of 60 patients characterized by nonproductive cough andlittle sputum were randomly assigned to receive Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution(Trial Group)or Ambroxol Hydrochloride Oral Solution(Control Group)l0 mL tid for 5～7 d.RESULTS:Both groups had a significant improvement in symptoms including cough and expectoration after treatment(P0.05).CONCLUSION:Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution is more effective in relieving cough than Ambroxol Oral Solution,and it has certain effect in eliminating phlegm.In addition,it is safe and has little adverse reaction.

Described in this paper are the contents and objectives of embedded information service for research on aviation medicine in light of information access, identification and analysis in persons engaged in research on aviation medicine.

After the current situation of knowledge service in aviation medicine was analyzed, the major problems in restrict security systems, few information access approaches, and difficulties in team construction for the knowledge service in aviation medicine were pointed out, with measures that should be taken in knowledge service put for-ward, such as keeping abreast of the key task in research of aviation medicine, making use of open access re-sources, digitalizing paper-type resources, organizing and revealing the knowledge in resources by making use of information technologies.

Objective To study the effects of peroxisome proliferators-activated receptor gamma (PPA?r) on the biological characteristics of hepatic stellate cells (HSCs); Methods The activated HSCs were divided into four groups: control group, rosiglitazone group, GW9662 + rosiglitazone group and GW9662 group. The cell proliferation was determined with MTT colorimetric assay, The cell apoptosis was studied with flow cytometry. The expression of PPA?r, Type I collagen were detected by RT-PCR, Western blot and immunocytochemistry. Results MTT of HSCs in rosiglitazone group was (0. 49?0. 06) significantly lower than in control group ( 1. 00?0. 045 ), GW9662 group (0. 89?0. 043 ) , GW9662 + rosiglitazone group (0.78?0.049)(t = 15.59,14.68,8.07, P

AIM:To observe the effect of simvastatin on myocardial tissue after renal ischemia-reperfusion in-jury and its mechanism .METHODS:A rat model of renal ischemia-reperfusion injury was prepared by clamping the bilat-eral renal arteries for 45 min.The rats (n=36) were randomly divided into sham operation group , renal ischemia-reperfu-sion (I/R) group and simvastatin group with 12 rats in each group.The content of serum creatinine (SCr), blood urea ni-trogen ( BUN) and myocardial tissue malondialdehyde ( MDA) , the myocardial activity of lactate dehydrogenase ( LDH) , creatine kinase (CK) and superoxide dismutase (SOD), and the myocardial protein expression of Bcl-2 and Bax were de-tected.RESULTS:Compared with sham operation group , the content of SCr , BUN and myocardial MDA , and the myo-cardial activity of LDH and CK in I/R group were significantly increased (P<0.05), and the activity of SOD was signifi-cantly decreased (P<0.05).Compared with I/R group, the content of SCr, BUN and myocardial MDA, and the myocar-dial activity of LDH and CK in simvastatin group were significantly decreased ( P<0.05 ) , while SOD activity was en-hanced (P<0.05).The protein expression of Bcl-2 and Bax in sham operation group was less than that in I/R group (P<0.05), and the protein level of Bax in simvastatin group was significantly lower than that in I /R group (P<0.05), while the protein level of Bcl-2 was increased (P<0.05).CONCLUSION:Simvastatin has a protective effect on the my-ocardium of the rats with renal ischemia-reperfusion injury , and the protective mechanism may be related to the elimination of free radicals by simvastatin , increase in the protein expression of Bcl-2 and decrease in the protein expression of Bax .

AIMTo develop a pharmacokinetic model for the enterohepatic circulation of mycophenolic acid (MPA).

METHODSTwenty healthy volunteers were orally given a single dose of 500 mg mycophenolate mofetil. Plasma samples were collected during 48 hours and MPA concentration was measured by HPLC method. Pharmacokinetic (PK) model was established based on physiological and biopharmaceutical consideration and PK parameters were obtained using nonlinear mixed effect model.

RESULTSThe proposed model included an intestinal compartment and gall bladder compartment in addition to the central compartment. The predicted time-concentration curve and AUC0-t, Cmax, Tmax estimated by the established model were in agreement with the observations.

CONCLUSIONThe established model was well defined for the MPA disposition and could afford a useful approach for the further clinical investigation.

OBJECTIVESTo further discuss the method of evaluating curative effect on erectile dysfunction(ED).

METHODSClinical trials(Phase II) of sildenafil and phentolamine were both 8-week-long, randomized, double-blind and placebo-controlled. Not only the curative effect between each treatment group and placebo group but also between the treatment groups were compared. The dosage of sildenafil and phentolamine was respectively 50-100 mg and 40 mg.

RESULTSEfficiency, success rate of sexual intercourse and general curative effect in sildenafil and phentolamine groups were respectively 79.17%, 75.00%, 83.33% and 52.38%, 85.71%, 52.38%. The result revealed a statistically significant (P < 0.05) improvement over placebo. But no obvious differences were shown between the two treatment groups(P > 0.05).

CONCLUSIONSMost assessments of curative effect of ED drugs come from questionnaires answered subjectively by patients. The Lack of objective assessment criteria way lead to the non-conformity between trial results and clinical practices. So the curative effect of drugs shall be assessed more accurately and from more perspectives.
