The Information and Management Platform of Standardized Training of Residents in Liaoning Province is a comprehensive management platform with information network , containing the whole process of the standardized training for residents. Liaoning, the populous province, has too many management staff in training residents, so it is very necessary to explore the information-based method for the training management. This platform has realized the whole-course network management of resi-dent training, and many common functions such as the application of training base , on-line registra-tion, on-line real-time monitoring of trainees' daily training state, on-line graduation exam arrangement, and inquiry of statistical information of trainees in the province . It saves human and management costs , improves management efficiency , and orderly pushes forward the standardized of residents training.

Objective To investigate the inhibitory effects of Propionibacterium acnes (P.acnes) by 22 effective components of traditional Chinese medicines. Methods The susceptibility tests of P.acnes to 22 effective components of traditional Chinese medicines were performed. Results P.acnes was highly sensitive to both eugenol and cineole, and moderately sensitive to baicalin, emodin and others. The number of bacteria per oil field decreased obviously under microscopy and bacteriolysis was found after the treatment with those components. Conclusion Eugenol, cineole and other components of traditional Chinese medicines can inhibit P.acnes in vitro.

Objective To investigate the change of P300 of the attention - deficit/hyperactivity disorder children before and after they took litalin, according to this objective subject to guide the clinical treatment of ADHD children. Methods Using the looking se-ducible electricity stimulates 22 ADHD children, and check the change of latency and the rate of the wave before and after they took litalin. Results After ADHD children took litalin, their latency of P300 has decreased clearly, and the amplitude had no change. Conclusion The changes of P300 latency in ADHD children after they took litalin can be adopted as the guidelines of clinical treatment for the ADHD children.

Objective To investigate the effect of ischemic preconditioning (IPC) on coronary microcirculation function in short-term hibernating myocardium(SHM) animal model.Methods Twelve little domestic Chinese pigs were established as the model of SHM by interventional method (closed-chest) and divided into 2 groups at random: the control group (CON group, n =6) and ischemic preconditioning group (IPC group, n =6).IPC was elicited by 2 cycle of 5 min of ischemia followed by 5 min of reperfusion before the establishment of model.Intracoronary Doppler guidewire was used to measure average peak velocity (APV),diastolic systolic velocity ratio(DSVR) and coronary flow reserve(CFR) of the distal to the stenosis at the baseline and 10 min,30 min,60 min,120 min after the establishment of model.Results APV,DSVR and CFR all decreased significantly in SHM model in both groups( P 0.05 ),at 60 min CFR of the CON group decreased significantly than before( 0.96 ? 0.27 vs 1.74 ? 0.49 , P 0.05 ).Conclusions The coronary microcirculation dysfunction happened at the time point of 60 min after coronary stenosis in SHM model,IPC can protect the coronary microcirculation function in SHM model.

Objective To explore the clinical features and diagnosis of primary immunodeifciency disease caused byTyk2 gene mutations.Methods Clinical data from the ifrst case in China diagnosed of primary immunodeifciency disease caused by Tyk2 gene mutation were retrospectively analyzed, and related literature was reviewed.Results One year and 3 month old boy suffered with repeated pulmonary infection, chronic otitis media, intractable eczema like rash, repeated skin abscess, HSV infection, intracellular bacterial infection, and remarkedly increased total IgE. It was detected that compound heterozygous mutations of c.2269C>G in No. 16 exon and c.149delC in No. 3 exon inTyk2 gene. Literature searching found other 8 cases (5 males and 3 females) of immune deifciency patients caused byTyk2 gene defects, all of which hadTyk2 gene homozygous mutations and presented with repeated infection of paranasal sinus and lung. In the 8 cases 6 cases were combined with mycobacterium tuverculosis infection, 4 cases had repeated virus infection, 4 cases had meningonecephalitis, 3 cases had intractable eczema like rash, 2 cases had salmonella enteritis, 1 case had remarkedly increased total IgE, one case had elevated eosinophils, 5 cases were born in intermarriage family and 1 case died of meningitis caused by unknown etiology.Conclusions When patients have repeated paranasal sinus infection and lung infection, combined with intracellular bacterial infection (including mycobacterium tuberculosis infection), and repeated virus infection or intractable eczema like rash, with or without increased total IgE, immunodeifciency disease caused by Tyk2 gene defection should be considered. Gene sequence analysis can assist in early diagnosis.

Objective To investigate the protective effects of hyperbaric oxygen(HBO)against brain dam- age from hypoxic ischemia(HIBD)in neonatal rats.Methods One hundred and seventeen 7-day-old Sprague- Dawley rats were randomly divided into 4 groups:a control group(n=32),a hypoxic ischemia brain damage group (HIBD group,n=30),a hyperbaric air group(HBA group,n=27),and a hyperbaric oxygen group(HBO group, n=28).The HIBD model was established by permanent occlusion of the left common carotid artery followed by expo- sure to a mixture of 8% oxygen/92% nitrogen for 2 h(at 37℃).HBO therapy was administered to the HBO group after the hypoxia exposure once a day for 7 d,as was HBA therapy to the HBA group.Apoptotic cells in the cortex and hippocampus(A_(CH)cells)were measured using TUNEL at 9 d after birth,and the ratios of left and right cerebral hemisphere weight(R_(L/R))and rate of weight gain(GRW)were recorded 14 d after birth.A radial arm maze acquisi- tion test(RAMAT)was administered at 30 to 35 days.Lastly,the neuron density in the CA_1 subfield of the rats' hip- pocampi(ND_(CAI)was measured with Nissl staining.Results R_(L/R)and GRW in the HIBD group were significantly lower than in the control group(P＜0.01),while R_(L/R)was increased in the HBO and HBA groups,especially in the HBO group(P＜0.01),although there was no significant difference in GRW between the groups.Compared with the control group,A_(CH)cells were increased and ND_(CAI)was decreased in the HIBD group(P＜0.01),while A_(CH)cells were decreased and ND_(CAI)was elevated in the HBO group in comparison with the HIBD group(P＜0.01).There was no change in A_(CH)cells or ND_(CAI)in the HBA group.The RAMAT results for the HIBD group,including the time to find the arms baited with water,average times of working errors and reference memory errors,were significantly high- er than those of the control group,while these values for the HBO group were obviously lower than for the HIBD group,and there was no change for the HBA group(P＞0.05).Conclusion HBO therapy might increase the re- covery of learning and memory function by attenuating HIBD in neonatal rats.

Objective To analyze the pregnant outcome of women with chronic hypertension,and to investigate the high risk factors associated with harmful maternal and perinatal prognosis.Methods Of the 14127 deliveries in Peking University First Hospital from Jan 2001 to Dec 2005,121 pregnant women with chronic hypertension were identified and divided into two groups:chronic hypertension with and without preeclampsia(group PE,64 cases;group N-PE,57 cases).The maternal and perinatal outcomes of the two groups and the high risk factors for adverse maternal and perinatal prognosis were analyzed.Results(1) The incidence of pregnancy with chronic hypertension was 0.86%(121/14127).(2)The incidences of placental abruption,pulmonary edema and retinopathy in groups PE and N-PE were 16%(10/64)vs 2% (1/57),11%(7/64)vs 0 and 41%(26/64)vs 16%(9/57,P

OBJECTIVE:To investigate the effects of hydrophilic polymers on the stability of self-microemulsifying drug deliv-ery systems (SMEDDS). METHODS:Taking felodipine (FDP) as model drug,the content of FDP was determined by HPLC method. The effects of pure water,0.5% Kollidon VA64,HPMC E5,HPMC K100LV,HPMC K4M,PVP K30 solution,while 0.1%,0.5% and 1.0% HPMC E5 and Kollidon VA64 on residual content of dissolved FDP were determined in SMEDDS. RE-SULTS:The residual contents of dissolved FDP in SMEDDS placed in Kollidon VA64,HPMC E5,HPMC K100LV,PVP K30, HPMC K4M and pure water for 1 h were 92.7%,63.6%,50.2%,46.2%,36.0%and 24.0%,respectively. The order of maintain-ing the supersaturation state was Kollidon VA64>HPMC E5>HPMC K100LV>PVP K30>HPMC K4M>pure water. The residu-al contents of dissolved FDP in SMEDDS placed in 0.1%,0.5%,1% Kollidon VA64 and HPMC E5 and pure water for 1 h were 93.2%,95.1%,96.0% and 48.4%,62.1%,75.1%. CONCLUSIONS:Kollidon VA64 and HPMC E5 can significantly inhibit drug release in SMEDDS and be used as stabilizer of SMEDDS,wherein Kollidon VA64 was better.
