Purpose To analyze the clinical pathological characteristics and pathological diagnosis and prognosis of spindle cell carci-noma of the breast. Methods Three cases of spindle cell carcinoma of the breast were studied by morphological and immunohisto-chemical EnVision techniques. Results The females were 48, 63 and 71 years old. The tumors located in the right breast with 4. 0 cm × 3. 0 cm × 3. 0 cm, 3. 0 cm × 2. 0 cm × 2. 0 cm and 3. 5 cm × 2. 8 cm × 2. 3 cm in size and showed cystic lesion. The neoplasm was composed of bland spindle cells and mimicking fibromatosis. Immunohistochemical staining showed that spindle cells were positive for CK(AE1/AE3), CK(34βE12), CK14, CK5/6, p63 and vimentin, negative for ER, PR and c-erbB-2. Ki-67 was positive in 20%, 25% and 20% of the cells. Conclusion Spindle cell carcinoma of the breast is a rare subtype of the metaplastic carcinoma which tend to show cystic changes. It is important to make a definite diagnosis which combine histopathologic features and immunophe-notyping.

Objective To investigate effects of problem-based learning (PBL) and traditional learning (TL) on students' long-term memory and clinical practice ability. Methods Totally 79 5-year-program undergraduates of 2006, 2007, 2008 grade in school of clinical medicine of our hospital were randomly divided into PBL group (n=38) and TL group (n=41). The teaching effects were evaluated by two exams as well as teachers' subjective impression. SPSS 17.0 statistical analysis software was used;exam results were expressed as x±s; t test and rank sum test were used to analyze the exam results and subjective impression. α=0.05 was set as inspection level. Results In the second exam after 6 months, the mean exam scores were (76.66 ±5.94) and (73.59 ±5.74) in PBL group and TL group, without significant differences between the two groups (t=1.85, P=0.068). However, at clinical intern-ship stage, PBL group outperformed TL group based on the subjective evaluation (P=0.065, 0.277). Conclusion PBL can culture students' ability of problem-solving, but it is limited in culturing long-term memory.

In order to study the the impact of cognitive difference between doctors and patients on doctor-patient relationship, five tertiary hospitals in city B were investigated with questionnaire and quantitative interviews, and the outcomes were analyzed with SPSS16. 0 software. Cognitive differences were found in the nature of the relationship, the main part of responsibility for the relationship, and principles for communication between the parties. By analyzing the causes of the difference and their impact on the relationship, it draw the conclusion that this cognitive difference found between the two parties functions as a key to the conflicts between doctors and patients. Return of health care back to non-profit nature, encouragement of patient-doctor communication and mutual understanding will be conducive to minimizing such a cognitive difference, and building a harmonious doctor-patient relationship.

Objective To summarize the clinical efficacy of interventional treatment for lower extremity arteriosclerosis obliterans and its complications.Methods We analyzed sixty-nine patients with lower extremities arteriosclerosis obliterans undergoing interventional treatment from October 2011 to January 2013.During the same period,three patients were referred to us who suffered from the complications of interventional treatment.In these patients,eight were TASC ⅡA type,twenty-one were TASC Ⅱ B,twenty TASC Ⅱ C,and twenty-two TASC Ⅱ D lesions.All patients received CTA or DSA.Seventy patients were treated by interventional treatment,and two who had fractured stent underwent external iliacsuperficial femoral artery bypass grafting using artificial grafts.Results The technique success rate was 100％.The symptoms disappeared after surgery.During interventional treatment,one iliac artery ruptured,one patient suffered from arterial perforation and three patients suffered from distal embolization.Sixty-eight patients were followed-up for 9 ± 4 months.Conclusions Endovascular treatment has good early clinical efficacy.In order to reduce the incidence of complications,indication of interventional treatment should be controlled strictly and manipulation should be careful.

OBJECTIVETo study the influence of Jiangzhining decoction on the genetic expression of Liver LDLR of the rats suffered from hyperlipemia.

METHODLaboratory animals were male wister rats with hyperlipemia resulting from high fat feeding. Prescription was the douche of stomach with Jiangzhining decoction (200%) with a dosage of 1.4 g.kg-1, for 15 successive days. Total RNA was extracted from the liver tissue of treated rats and LDLRmRNA was detected by Dot blot hybridization. Expression levels of LDLRmRNA was estimated by a ratio of LDLRmRNA and beta-actin mRNA.

RESULTThe difference between expression levels of LDLRmRNA for normal group and those for hyperlipemia group (100% +/- 19% vs 39% +/- 14%) was significant (P < 0.05); and the difference between decoction group (108 +/- 8%) and hyperlipimia group was also highly significant (P < 0.01).

CONCLUSIONHigh fat feeding reduces the expression of liver LDLRmRNA while the decoction can greatly increase it. The study and development of Jiangzhining are significant in preventing and curing cadiocerebral diseases.

Objective To investigate the correlation between the types of constitution in TCM and the sleep status in the PLA Navy divers. Methods Eighty-nine PLA Navy divers who performed 10m diving professional training were selected. Constitution in TCM was classified and determined by the standardized standard Constitution in Chinese Medicine Questionnaire, sleep status was evaluated by the Pittsburgh Sleep Quality Index. Results 62.9% of Navy divers were the mild constitution in TCM. The eight kinds of the biased constitution in TCM are ranked with yang deficiency, phlegm-dampness, dampness-heat, qi deficiency, yin deficiency, blood stasis, qi stagnation and special intrinsic quality. Among 78 Navy divers with good sleep quality, there were 49 divers (72.1%) with the mild constitution in TCM and 19 (27.9%) with the biased constitution in TCM. Among 21 Navy divers with poor sleep quality, there were 7 divers (33.3%) with the mild constitution in TCM (accounting for) and 14 (66.7%) with the biased constitution in TCM. For Navy divers with poor sleep quality, the sleep quality scores were positive correlated with the blood stasis constitution in TCM (r=0.481,P<0.05). Conclusion Sleep status is correlated with the types of the constitution in TCM, and regulating constitution in TCM can improve sleep quality in PLA Navy divers.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.
