Objective To investigate the clinicopathological features of undifferentiated embryo-nal sarcoma of the liver (UESL). Methods The clinical data of 9 UESL cases treated in our hospital between 1996 and 2007 were retrospectively analyzed. Results The patients were children and young adults. Clinical presentation was typically an abdominal mass that may be accompanied by pain and fe-ver. Tumors were all removed surgically in the 9 patients. Conclusion UESL is an unusual malignan-cy of the liver. Discrepancy of internal architecture between US and CT is one of the important charac-teristic of UESL. Whenever feasible, surgical resection should be attempted as a part of combination modalities. Modern rnultimodal treatment and supportive therapy might promote the survival rate.

Aim To establish a new,multi-parameter,real time and qualitative cell migration evaluation method.Methods Lung cancer cell line A549 was cultured on the glass bottom dish.After treated with different dosages of berberine or Rg3 for 24 hours,several scratching lines at the same dimension were made and observed by Living Cell Working Station.8 observation areas were selected randomly and imaged continuously for 24 hours.Transferred Area(TA),Transferred Distance(TD),Single Cell Transferred Speed(SCTS)and the Cell Division Number among defined area(CDN)were analyzed after getting sequence images.Results The focus stage and the incubation system were sufficient to keep cell proliferation and made it possible for long term observation.Berberine at 25 μmol·L~(-1) and 12.5 μmol·L~(-1) could inhibit the migration of A549(P<0.01).The analysis results of TA,TD,SCTS and CDN were basically coincident.Rg3 at 0.1 mmol·L~(-1) could inhibit SCTS and promote CDN in 6,12 and 24 h(P<0.01),while decrease both TA and TD in 24 hs.Conclusion The method is sensitive,rapid and simple to be applied in the research of tumor metastasis,wound healing and inflammatory response with real time,in-situ and multi-parameters.

AIM: To control the quality of Er Chen Pill (Pericarpium Citri Reticulatae, Rhizoma Pinellae, Poria, Radix Glycyrrhizae) by determination of limonene by GC. METHODS: HP 6890 GC instrument was employed to determine the content of limonene with column (HP-1 Methyl Siloxane 30m?320?m?0.25?m), detector temperature (250?C), injection temperature (250?C), split ratio (100∶1) and injection amount (1?L). RESULTS: The calibration equation was Y=0.9873X+0.0794(r=0.9995) in the range of 0.45?g～ 1.80?g. The average recovery was 99.6%(RSD=6.9%) and the average content of limonene in the sample was 78.4mg?g -1(RSD=3.2%). Conclusion: The method is simple, quick, and sensitive.

Objective To study the effect of cardiac troponin T(cTnT)on the prognosis of chronic heart failure in the elderly patients.Methods Serum level of cTnT,and serum activities of creatine kinase (CK)and creatine kinase-MB(CK-MB)were measured in 60 elderly patients of chronic heart failure with varied classes of cardiac function.Cardiac events,including malignant cardiac arrhythemia,repeated or aggravated heart failure or cardiac death,in patients with increased cTnT during hospitalization were compared to those without it.Results Serum level averaged(89.1?13.6)mmol/L for CK and(7.9? 1.4)mmol/L for CK-MB in 20 patients with Class Ⅱ cardiac function by New York Heart Association (NYHA)classification and without increased cTnT,(88.2?13.4)mmol/L for CK and(7.5?1.8) mmol/L for CK-MB in 19 patients with Class Ⅲ cardiac function and four of them with increased cTnT,and (93.3?14.2)mmol/L for CK and(8.1?1.6)mmol/L for CK-MB in 21 patients with Class Ⅳ cardiac function and 14 of them with increased cTnT.Malignant cardiac arrhythemia occurred in six,repeated heart failure in eight,and death in three of 18 patients with increased cTnT,and one,two and one in 22 patients without increased cTnT,respectively.Incidence of cardiac events was higher in patients with increased cTnT than those without it(P

Objective:To explore the methods to improve the professional core competencies of medical students in the standardized residency training.Methods:A total of 82 medical students who participated in the standardized residency training ("resident students" for short) in the same period were selected in this study, and the self-edited professional core competencies textbooks were used for regular theoretical study, and at the same time, clinical practice cases were collected for regular scenario reduction teaching. When the resident students entered the department and after 12 months of the standardized training, the professional core competencies training evaluation scale was used to evaluate and compare the scores of the resident students, and the value of the above-mentioned training model to improve the professional core competencies of the resident students was evaluated. SPSS 18.5 was performed for t test between groups. Results:After being trained by the above model, the selected students had significantly improved such competencies as communication, cooperation and problems solving ( P<0.05). Compared with the scores of resident students before and after the training, there was no significant difference in communication and cooperation with other students ( P>0.05), with low satisfactory communication with the leader ( P>0.05), but the problem-solving ability had been significantly improved ( P<0.05), while the score of which was low and it should be pay more attention to in the future training. Conclusion:In the process of standardized residency training, the application of the above-mentioned training model can significantly improve the professional core competencies of resident students, and at the same time, it's necessary to strengthen the cultivation of satisfactory communication with leaders and problem solving ability.

Objective To observe the of changes of cerebral blood flow and electroencephalography in chronic cerebral circulation insufficiency (CCCI) treated with fastigial nucleus stimulation (FNS) and hyperbaric oxygen (HBO). Methods 144 cases of CCCI were divided into 4 groups: 36 cases were treated with FNS and HBO, 36 cases with FNS, 36 cases with HBO, 36 cases without any treatment as control group. The blood velocity of anterior, middle, posterior cerebral arteries, vertebral artery and basilar artery were measured with transcranial Doppler (TCD) and the brain waves （α, β, δ, θ） were recorded with electroencephalography (EEG) before and after the treatment. Results Compared with the control, the brain blood velocity and α wave increased in all the treatment groups, especially in the HBO+FNS group, while β, δ, θ waves decreased (P<0.05). Conclusion FNS and HBO can increase cerebral blood flow and improve the cerebral function respectively.

Objective To observe the clinical effect and comfortable degree of the mode of super hair removal. Methods The mode of super hair removal was used to depilate the hair nearby the hair line, cheeks, upper lip, beard, ventrum, areola of breast, axillary cavity, extremities, bikini area and so on. The total number of sites was 1 000. Some sites that were especially susceptible to pain, for example, upper lip and buccal region, were smeared with compound lidocaine cream for 1 hour at least before treatment. Results Hairs in the areas of extremities, ventrum, back and axillary cavity generally needed 4 to 5 times to eradicate, and the patients had no evident discomfortableness; hairs near to the upper lip and lower mandible generally needed 5 to 7 times to reach the effect which the patient was content, and anesthetics was indispensable, or the patients would present discomfortableness. Conclusions The mode of super hair removal is more effective, quicker and more comfortable in comparison with conventional methods. Therefore, it deserves to be spread.

Objective: To evaluate the efficacy of 3LL/GM-CSF tumor vaccine combined with pacilitaxel chemotherapy in treatment of mice bearing transplanted Lewis lung carcinoma. Methods: The tumor vaccine 3LL/GM-CSF was prepared by infecting Lewis lung carcinoma cell line 3LL with adenovirus encoding GM-GSF. Mice model of Lewis lung carcinoma was established by subcutaneous injection of 2?104 3LL cells into C57BL/6(H-2b)mice. The sensitivity of Lewis lung carcinoma cell line-3LL to the treatment of pacilitaxel was detected in vivo and in vitro. The mice tumor model was first treated with pacilitaxel chemotherapy and then with 3LL/GM-CSF, or first with 3LL/GM-CSF and then with pacilitaxel. Tumor growth and the long-term survival of mice were observed after treatment. The immune memory and cytotoxicity against target cells were studied in the mice. Results: Pacilitaxel at 100 nmol/L killed 32.10% 3LL cells after 24 hour in vitro; but pacilitaxel at 5-25 mg/kg only had a poor effect on growth of 3LL cells in vivo. The tumors rebated in 70% of mice treated with pacilitaxel chemotherapy and 3LL/GM-CSF vaccination successively, and the survival of these mice was obviously longer than that of pure pacilitaxel chemotherapy group (70.0 days vs 27.5 days). The killing rate of 3LL/GM-CSF after pacilitaxel chemotherapy was 41.35% on day 3. Meanwhile, the survival mice could resist the re-attack of 3LL cells (2?104). We also noticed that first treatment with 3LL/GM-CSF and then pacilitaxel chemotherapy had no effect on tumors. Conclusion: Application of tumor vaccine shortly after pacilitaxel chemotherapy can induce specific immune responses and prolong the survival of experimental mice, which provide a basis for future clinical practice.

Objective Under the guidance of CT and three dimensional reconstruction, we made therapeutic plan for lung cancer by radiofrequency ablation (RFA) and observed its effect. Methods From February 2007 to January 2009, we used RITA radiofrequency therapeutic equipment to treat lung cancer under the guidance of 64-slice spiral CT (Siemens) and three dimensional reconstruction of the image. The target temperature is 90℃. Results We performed 29 RFA on 25 patients. In the follow-up, 10 of them showed tumor shrinkage by CT scan. 23 showed lack of tumor-uptake value by SPECT scan and 2 showed lower tumor-uptake value. Conclusion CT-guided percutaneous RFA is safe and practical for lung cancer. It has satisfactory short-term effect to reduce tumor burden.
