Objective:To find out markers of endometriosis. Methods: The two dimensional gel images of proteins extracted from eutopic endometrium from endometriosis patients and controls were analyzed by software Phoretix 2D,and the proteins expressed differently were identified primarily by query of data base.The proteins extracted from ectopic endometrium of ovarian endometriosis were transferred from two dimensional gel onto nitrocellulose membranes,followed by incubation with sera from women with and without endometriosis. Analyzed by MALDI-TOF-MS,the proteins hybridized differently were identified through their Peptide Mass Footprints. Results: Having compared the reproducible two dimensional gel images of proteins from eutopic endometrium of women with and without endometriosis,we obtained 11 proteins expressed differently.Through Western Blot technique,we found three proteins hybridized differently which were identified as vimentin,?-actin and ATP synthase ? subunit respectively. Conclusion: The protein expression spectra of eutopic endometrium from patients with endometriosis are significantly different from those of the controls,and the anti-endometrial autoantibodies against vimentin, ?-actin and ATP synthase ? subunit may be induced.

ObjectiveTo explore the appropriate teaching methods for medical international students.MethodsTotally 84 students in grade 2005 and 63 students in grade 2006 took part in clinical skills training in 2010 and 2011.The traditional method was employed in grade 2005 and interactive teaching and imagery training was applied in grade 2006 combined with the traditional methods.ResultsThe scores of clinical skill tests ( posterior thorax puncture test,abdomen puncture test,bone puncture,catheterization test) were significantly higher in grade 2006 than in grade 2005 with statistical differences,P ＜ 0.01.The clinical skill test scores were not statistically different between grade 2005 and 2006 before training,P ＞ 0.05,but the scores were statistically different between grade 2005and 2006 after training,P ＜ 0.05.Conclusion Using polynary teaching methods synthetically is helpful to improve the clinical skill training effect for medical international students.

Cycloheximide (CHX) inhibits protein synthesis in most eukaryotic cells and it is a well-known tool commonly used in biochemical research. In this paper, the antiviral spectrum of CHX against several DNA and RNA viruses have been evaluated. CHX showed strong inhibitory activities against several RNA viruses such as HIV-1, influenza viruses, coxsackie B virus, enterovirus (EV71) and several DNA viruses such as HSV and HCMV. Especially the strong inhibitory activities of CHX against coxsackie B virus and enterovirus caught our attention, since effective drugs available in clinic are limited. The SAR of CHX derivatives also has been discussed in the paper. The hydroxyl group at C-2' and carbonyl group at C-2" of CHX are essential for its antiviral activity. And modification to these groups results its derivatives' antiviral activities reduced or lost.

OBJECTIVE To investigated the impact of age,sex and season on the morbidity of allergic rhinitis(AR)and noninfectious,nonallergic rhinitis(NINA).METHODS The clinical data of the patients with AR and NINA was analyzed from Oct.2003 to Oct.2005.Factors such as age,sex, etc were taken into consideration.RESULTS The highest morbidity age of AR was 10～19 years, and that of NINA was 30～39 years.The morbidity of allergic rhinitis in men was higher than that in women before 20 years old,while there was no sexual difference of nonallergic rhinitis.About 61.6% of patients diagnosed with AR developed their condition before 20 years old,about 66.5% of patients diagnosed with NINA developed their condition after 20 years old.The number of patients with AR increased markedly from July to November, while there was no seasonal diversity of NINA. CONCLUSION There were obviously differences between AR and NINA of age,sex and seasons, which implied different pathologic mechanism between these two types.

Objective To observe the cognitive function and its related factors in patients with essential epilepsy.Methods The cognitive function of 70 essential epilepsy patients (epilepsy group) and 40 healthy controls(control group) were evaluated by means of Wechsler Intelligence Scale for Adult-Chinese (WAIS-RC).The relation between the cognitive dysfunction and its related factors were analyzed.Results The scores of performance intelligence quotient,verbal intelligence quotient,full intelligence quotient in epilepsy group were significantly lower than those in control group [(98.06 ± 15.24) scores vs.(113.80 ± 12.14) scores,(98.09 ± 16.06) scores vs.(120.65 ± 11.28) scores,(98.06 ± 15.80) scores vs.(119.42 ± 11.85) scores] (P ＜ 0.01).The scores of 11 numbers of rating scales were significantly lower than those in control group (P ＜ 0.01).The factors related to the cognitive function were education level,age numbers,duration of the disease,frequency of seizures attack before medication,the duration of seizures and the quantity of antiepileptics.Conclusions Many of the essential epilepsy patients have cognitive function deficit.The cognitive condition of essential epilepsy patients should be pay more attention and reduce the dangerous factors in order to improve the life quality.

Obejective To reform the electrocardiogram teaching mode under clinical pathophisioligy and therapy(CPPT) mode.Methods The junior students of Grade 2010 in Second Clinical Medical College of Wuhan University were selected as subjects.The students were randomly divided into experimental group (44 students) and control group(52 students).Control group was taught by using traditional methods for electrocardiogram(ECG) diagnostics theory,and by using Diagnostics department's own Atlas,while experimental group was taught by reformed teaching methods,and ECG reformed textbook was used in their theoretical lessons,strengthening electrocardiogram and electrophysiology,cardiovascular disease combined.Meanwhile,the practice of teaching was taught by using preview-speaking Figure-Picture stories-Case-Read figure,a way to strengthen the theory-practice-theory of the cycle.The questionnaire was carried out in two groups after ECG teaching.After the end of the course two groups were given packet electrocardiogram atlas test and ECG theoretical knowledge examination and the above evaluation results were statistically analyzed by using SPSS 10.Results The statistically significant differences between experimental group and the control group were in the right ventricular hypertrophy,ventricular fibrillation,WPW syndrome,et al(P＜0.05).The ratio of the experimental group students' liking electrocardiogram course and their recognition of electrocardiogram teaching mode was higher than that of the control group while the ratio of their thinking ECG difficult was lower than that of the control group and the difference was statistically significant difference(P＜0.05).The excellent rate and good rate of the experimental group students' theory knowledge examination results were higher than the control group,two groups of results distribution difference being statistically significant(P=-0.043).Conclusions CPPT teaching model can effectively help students overcome the difficulties in reading electrocardiogram and deepen their understanding of theoretical knowledge and memory.

Objective:To evaluate the efficacy of specific immunotherapy (SIT) with standardized dermatophagoides pteronyssinus extract for allergic rhinitis (AR)accompanied with asthma.Method:One hundred and fifty-five patients(40 AR with asthma, AR & asthma) in accordance with the inclusion criteria of SIT, were allocated to receive standardized Dermatophagoides pteronyssinus extract (SIT group, n=89) or medical treatment(control group, n=66). AR with or without asthma was observed separately. Symptom and medicine scores, quality of life were recorded and analyzed before and after 1 year treatment. Side effects were registered. Subjective evaluation of symptoms was made by the patients.Result:Rhinitis and asthma symptom scores, medicine scores and quality of life were greatly improved in SIT group of AR & asthma after 1 year, which were not significant changed in control group except for medicine scores. The subjective evaluation of symptoms was also significantly improved in SIT group. In patients of AR without asthma, the symptom scores, medicine scores and quality of life were both improved. The SIT group improved greater than that of control group.Conclusion:The clinical efficacy of patients with AR & asthma was not good with simple medical treatment, while great clinical efficacy could be acquired with SIT.

Objective To evaluate the effect of targeted monitoring and comprehensive intervention measures on reducing the occurrence of catheter-associated urinary tract infection(CAUTI)in patients in non-intensive care unit(Non-ICU).Methods In quarter 4 of 2015,patients with indwelling urinary catheter in clinical departments were conducted a baseline survey(before intervention),risk factors for CAUTI in patients were analyzed,targeted monitoring programmes and comprehensive intervention measures were initiated in 2016(after intervention),incidence of CAUTI before and after intervention was compared.Results After taking intervention measures,hand hygiene compliance rate increased from 78.51%in quarter 4 of 2015 to 92.99%in quarter 3 of 2016 and 90.73%in quarter 4 of 2016(x2=7.342,3.998,respectively,both P<0.05),the correct disposal rate of patients' urinary catheterization system increased from 72.83%in quarter 4 of 2015 to 95.44%in quarter 4 of 2016(x2=30.267,P<0.05).A total of 12 067 patients with indwelling urinary catheter were monitored,incidence of CAUTI dropped from 1.03%(24/23 313)in quarter 4 of 2015(before intervention)to 0.53%(14/26 595)in quarter 4 of 2016(after intervention),difference was statistically significant(x2=4.126,P=0.042).Conclusion Improving the quality of urinary catheterization system in patients with indwelling catheter through targeted monitoring can effectively reduce the incidence of CAUTI in patients in Non-ICU.

OBJECTIVETo evaluate applicability of power Doppler sonography (PDS) in differential diagnosis of small hepatocellular carcinoma (SHCC) and adenomatous hyperplastic nodule (AHN).

METHODSTwenty-two cases of SHCC and 15 cases of AHN were investigated by PDS and the findings were compared with those of digital subtraction angiography (DSA).

RESULTSThe rates of arterial and portal flow in an afferent tumor vessel were 86.4% and 40.9% in SHCCs, respectively. The rate of portal flow in an afferent tumor vessel was 60.0% in AHNs, while no arterial flow was detected (P < 0.01). In addition, PDS revealed a constant flow in an efferent tumor vessel (50.0%) continuing to a portal branch in 10 (45.5%) of the 22 SHCCs cases to a hepatic vein in 1 (4.5%) of the 22 SHCCs, but to nothing else in the AHNs (P < 0.01).

CONCLUSIONSPower Doppler sonography is of value in distinguishing SHCC from AHN, and arterial afferent tumor vessels from constant flow efferent tumor vessels at PDS.
