Objective To explore and establish the effective model of assessment for residen-cy training. Methods Totally 181 residents completed general specialist stage of resident training of Liaoning province in 2010. Assessment process was designed and implemented for general specialist training stage, including theory exam (basic knowledge, professional knowledge and public knowledge) and objective structured clinical examination (OSCE) (standardized patient(SP), computer-based case simulations(CCS) and clinical skills operation). T test and variance analysis were used and P≤0.05 stands for statistically significant difference. Results The total results consisted of two parts, theory examination results (40.00%) and OSCE results (60.00%) and two students failed the examination. The mean score of OSCE was up to standard (66.58±5.50). The mean score of SP and CCS was close to standard. The mean score of clinical skills operation reached a good level. In terms of the OSCE, SP examination and CCS examination, the performance of residents from the two universities had sig-nificant difference (t=3.818, P=0.000; t=5.581, P=0.000; t=5.419, P=0.013) and the performance of residents from the five hospitals also had significant differences. Conclusions The assessment of standardized resident training is improving gradually. Through the widespread application of OSCE in the assessment;it could be helpful to the clinical training of residents.

Objective The empirical validity of the National Medical Licensing Examination (NMLE) has rarely been studied. This is one of the first studies comparing NMLE and annual assess-ment scores. This study provided the criterion-related validity evidence for the NMLE. The NMLE can be used to test the abilities and skills of physicians. Method We evaluated the test 163 residents in 12 medical school-affiliated hospitals who had finished their first year of tralning and had taken the NMLE and an annual skills assessment. We used Pearson correlations to estimate the relationship be-tween NMLE scores and annual assessment scores. Results A total of 163 residents met inclusion requirements. Correlations between NMLE scores and annual assessment scores ranged from 0.300 to 0.843. Conclusions The criterion-related validity of NMLE was high, so it can be use to evaluate the residents clinical competence indeed.

Objective To compared the condition of DSA and MRA for detection the lesion vessels in elder patients with recurrent ischemic cerebrovascular disease(ICVD).Methods 52 patients with ICVD,including 41 cases of cerebral infarction(CI) and 11 cases of transient ischemic attack(TIA) were detected by DSA,and the 44 cases of them were detected by MRA too.Results The vascular anomalies were detected in 43 cases(82.69%) of the 52 patients by DSA.Among them,39 cases(75%) had vascular stenosis,in which 31 cases(75.61%) were CI,and the other 8 cases(72.73%) were TIA.The aneurysm were founfd out in 2 cases,and vascular dysplasia and variation were also found in each 1 case by DSA.The vascular stenosis were found in 10 cases(22.73%) of 44 patients by MRA,in which 8 cases(18.18%) were CI,while 2 cases(4.55%) were TIA.The detection rate of lesion vessels in DSA was significantly higher than that in MRA(P

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 effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

Objective To study gastroscopic features and clinical diagnosis of prepyloric mem-brane. Methods Clinical characteristics,gastroscopic manifestation and operational findings of 18 pa-tients,whose prepyloric membrane have been confirmed by operations,were retrospectively reviewed. Results Gastroscopie findings showed that all the 1 8 patients suffered gastric retention and pyloric obstruc-tion to some degree,with 4 cases of esophageal erosion and/or esophageal ulcer,five cases of erosive hemor-rhagic gastritis,one case of ulcer at gastric antrum,gastric comer and pylorus respectively. There were 2 ca-ses of aperture like narrowing in prepyloric region. And there were 9 cases that showed obvious congestion and edema in the prepyloric mucus,with uniform circular mucusal protrusion around the stenosing stoma,and volcano-like depression in the middle,three cases of which showed mucosal membrane standing out to the gastric cavity. The membrane found in the above 11 cases located in pyloric exit or tube,and they under-went membrane excision and py|oroplasty. The other 7 cases showed thick mucosal folds at the distal antrum with radial arrangement. Round or irregular stenosing stoma were observed. These cases proved to be antral membrane,1-3 cm away from the duodenum and pylorus,and underwent simple membrane resection. Conclusion Congenital prepyloric membrane is rare and it likely mis-diagnosed. The onset and the degree of symptoms depend on the diameter of aperture of the membrane. Early endoscopy,in addition to barium contrast,should be performed on those children who have intermittent bilious vomiting,where false-positive radiological findings can be avoided,therefore,to facilitate right diagnosis and appropriate operation.

Stage assessment is an important part of standardized resident training.After two years of practice and exploration,Liaoning had established the complete examination and evaluation system including the theory test and skill test and this system was future improved through analyzing two years' results and summing up the experiences making it more suitable for residency training in the future.
