Chinese Journal of Medical Education Research 2013;(6):584-586
Objective To investigate the teaching effects of Sandwich teaching mode applied in clinical oncology teaching.Methods Totally 72 clinical medicine undergraduates were divided into two groups randomly:Sandwich teaching group and traditional teaching group.Sandwich teaching mode was introduced to Sandwich teaching group while traditional teaching mode was carried out in traditional teaching group.Questionnaires and test paper were analyzed between the two groups and two teaching modes were evaluated.Examination results were statistically analyzed by t test.Results According to the questionnaires,more than 80 percent of the students thought that the initiative and enthusiasm were fully mobilized by the Sandwich teaching mode.Studying efficiency was improved significantly and skills of independent thinking,comprehensive analysis and problem-solving were trained,meanwhile,Sandwich teaching mode can improve the ability of expression and communication.Test score of students in Sandwich teaching group was higher than those in traditional teaching group (P<0.05).Conclusions Sandwich teaching mode has obvious advantages in improving teaching quality of clinical oncology and it may help to cultivate high quality oncology specialists.

Cavernous transformation of portal vein accounts for about 40% in children portal hypertension.Compared with other causes of portal hypertension disease cavernous transformation of portal vein presents early age of disease onset,high risk of bleeding and normal liver function.Because the pathology is relatively simple and most children have no other diseases,so a reasonable treatment of the disease has decisive significance.The current concept for diagnosis and treatment of the disease is different between home and abroad,Controlling upper gastrointestinal bleeding is the main purpose in out country.Reliving hypersplenism,improving liver blood supply and quality of life are much important abroad,The article aims to summarize latest foreign literature to introduce latest research for the disease abroad.

Objective To investigate the effect and mechanisms of the Berberine on the human breast adenocarci-noma cell line MCF-7 . Methods MTT method was used to evaluate the proliferation effect of MCF-7 and the per-centage of apoptotic cells were determined by flow cytometric analysis. The expressions of JAK2, p-JAK2, p-STAT3, STAT3, Bax, Bcl-2, Cleavage-PARP and Cleavage-Caspase3 were detected by Western blotting. Results The results showed that BBR treatment decreased the activation of JAK2/STAT3 signal pathway and up-regulated the expression of Bax, Caspase3 and PARP activation with the decrease of the expression of Bcl-2. Wherefore, ex-pression of the constitutively active form of STAT3 could attenuate the effect of BBR on the MCF-7 cell. Conclusion Berberine can induces apoptosis and proliferation inhibition of breast adenocarcinoma cell lines of MCF-7 through inhibition of the JAK2/STAT3 signaling pathway.

Objective To analyze the examination results of external quality assessment(EQA),at all levels of iodine deficiency disorders(IDD) net work laboratories in Ningxia from 2002 to 2012,and to provide a reliable laboratory quality assurance for surveillance and control of IDD.Methods The data of IDD network laboratories at Ningxia provincial,municipal and county levels from 2002 to 2012 were collected and analyzed.Results Both of the response rate and qualification rate of salt iodine and urinary iodine laboratories at the provincial level were 100% in the past 11 years.The response rate and qualification rate of salt iodine laboratories at municipal level were also 100% ; the response rate of urinary iodine was 100% since 2005,and the qualification rate had been 100% for six years since 2007.The response rate of salt iodine at county level had been 100% since 2004,and the qualification rate had been 100% for four years since 2009.Conclusions IDD network laboratory in Ningxia Province runs good,and the quality control measures are solid and effective.

Objective To explore the relation between thyroid nodular and thyroid calcification .Methods The clinical data of 430 cases with nodular goiter admitted from January 2011 to December 2013 were reviewed.All cases were performed ultrasonography and pathologic examination .Results Of 430 cases,there was thyroid carcinoma in 49 cases(11.4%),including microcalcification in 30 cases(61.2%) and macrocalcification in 3 cases(6.1%);benign lesion in 381 cases(88.6%),including microcalcification in 24 cases(6.3%) and macrocalcification in 39 cases(10.2%).The difference was remarkable (P=0.000).There was remarkable difference in malignant calci-fied nodules ratio between the patients with microcalcification and macrocalcification (55.6%vs 7.1%,P=0.000), between the patients aged 45 years below and above(48.8%vs 22.6%,P=0.007),between the patients with solita-ry and multiple nodules(45.0%vs 16.7%,P=0.005).But there was no statistic difference in malignant calcified nodules ratio between the male and female groups (24.2% vs.39.7%,P=0.130).Conclusion Microcalcification is a highly specific sign to predict thyroid carcinoma in ultrasonography exam .Positive intervention will be performed immediately when calcification appears in thyroid nodules .

Objective To investigate the effects of single and combined exposure to ozone and nitrogen dioxide on airway injury and inflammatory levels in mice. Methods Eighty BALB/C mice were randomly divided into eight groups:four were sensitized model groups(the control group,the O3 group,the NO2 group and the O3+NO2 group based on the way of exposure) ,the other four were non-sensitized groups. The concentration of O3 was 0.16 mg/m3,NO2 was 0.30 mg/m3. Mice were exposed 2 hours every day for 7 consecutive days. Mice were sacrificed in the exposure end and cell counting and cytokine measurement from bronchoalveolar lavage fluid(BALF) were performed. Results In the sensitized groups,neutrophil proportion and IL-6 were significantly increased except the control group and IL-2 and MDA were also significantly increased in the O3 group and the O3+NO2 group(P

Forty-seven patients with congenital heart disease and pulmonary hypertension were treated surgically. Among them, 31 were male and 16 female. The age ranged from 2 to 47(13. 7? 11. 2) years. Gongenital heart abnormalities included ventricular septal defect (VSD) in 20, huge atrial septal defect (ASD) in 1, VSD+ASI) in 12, VSD with patent ductus arteriosus (PDA) in 6, endocardial cushion in 2, VSD with aortopulmonary septal defect (APSD) in 1, double outlet right ventricle with PDA in 1 and total anomalous pulmonary venous connection in 1. Right heart catheterization was performed in 15 cases. The mean pulmonary artery pressure was (73 ? 24)mmHg, total pulmonary resistance was (78. 0 ?61. 2)kPa/(L/s). There were 7 cases examined in operation. Their mean pulmonary artery pressure was (55?13)mmHg. The others were examined by echocardiography. The mean pulmonary artery pressure was (49?15)mmHg. All patients were treated pre-op-eratively with oxygen inhalation therapy, hyperbaric oxygenation, prostaglandin E1 , respectively according to the degree of pulmonary hypertension. During cardiopulmonary bypass, pulmonary artery perfusion was performed with protective solution containing aprotinin for lung protection. Vasoactive drugs were routinely administrated postoperatively. There were 2 operative deaths with hospital mortality rate of 4. 3%. The cause of deaths was severe low cardiac output syndrome. The postoperative morbidity rate was 4. 3%. Our conclusion is proper peri-operative management could reduce post-operative mortality and morbidity for congenital heart disease with pulmonary hypertension.
