Objective:To isolate breast cancer stem/progenitor cells from human breast cancer and study their proliferation and differentiation biological characteristics over long-term passages in vitro. Methods:Human breast cancer stem/progenitor cells were enriched in suspension cultures as nonadherent mammospheres(MS). Serial sphere formation assay was performed to determine self-renewal ability of mammosphere-derived cells (MSDC). Differentiation was induced by culturing MSDC in DMEM-F12 supplemented with serum but without growth factors. The ratio of CD44~+/CD24~(-/low) cell population was evaluated by flow cytometry(FCM). Results:The mammospheres were formed after inoculation of primary breast cancer cells into culcutre medium with growth factors but without serum. The mammospheres contained undifferentiated cells similar to stem cells, which had self-renewal and extensive proliferation capabilities. With increasing passages, the cells tended to adhere and differentiate. The number of adhering and differentiating cells increased, and the amount and size of mammospheres decreased. The CD44~+/CD24~(-/low) cell population was enriched in the basal-like molecular subtype of human breast tumors. The biological behaviors of mammospheres varied between different specimens.Conclusion:Cancer cells with stem cell properties of self-renewal, indefinite proliferation and multi-lineage differentiation widely existed in human breast cancer tissues. The biological behaviors varied because of different origin of specimens and changed under the effects of environmental factors.

Objective To evaluate the diagnostic value of 18F-FDG PET-CT in looking for tumor primary lesion with multiple bone metastasis.Methods 84 patients with suspected bone metastases were detected by routine imaging (X -ray,CT,MRI)in our hospital from May 2012 to September 2014 were selected,18F -FDG PET/CT were used to find the primary lesion.The final diagnosis were confirmed by tissue pathology or by clinical imaging follow -up.The diagnostic sensitivity,specificity and accuracy on tumor bone metastasis of 18F -FDG PET/CT were recorded.Results In 84 patients,primary tumor was found in 49 cases,of which 46 cases (54.8%)confirmed pri-mary tumor by operation or pathology,the other 3 cases were false positive;35 patients were diagnosed as non meta-static bone tumor by PET/CT,in which 34 cases were finally confirmed as non metastatic bone tumor by pathology and follow -up;accuracy,sensitivity,specificity of 18F -FDG PET/CT were 54.8%(46 /84),93.9% (46 /49)and 95.2%(80 /84);18 cases of lung cancer,9 cases of prostate cancer,7 cases of breast cancer,5 cases of lymphoma, 4 cases of renal cell carcinoma,2 cases of liver cancer,1 cases of Uterine sarcoma were included in 46 primary tumors.Conclusion 18F -FDG PET/CT has a higher specificity,accuracy as well as higher detection rate in search of multiple bone metastases,thus it is beneficial to the clinical therapy.

Methods A total of 80 elderly patients with rheumatoid arthritis were enrolled in the first Affiliated Hospital of Kunming Medical University from December 2014 to October 2016. The quality of life SF-36 score was used to measure the physical health, mental health, daily activities and social health to assess the overall health status of patients. The factors influencing the comprehensive health function of the patients were analyzed by univariate analysis and multivariate linear regression analysis. Results The univariate and multivariate analysis showed that the low level of education, general occupation, marital misfortune, poor economic condition and self-treatment expense were the risk factors affecting the comprehensive health function in elderly patients with rheumatoid arthritis ( P<0.05). Conclusion Elderly patients with rheumatoid arthritis have problems of the functions of daily life, physical health, mental health and social health. To alleviate the high medical costs, improve the level of medical treatment, improve the people 's health and education level and maintain a good mood are the key to improve the overall health in patients with rheumatoid arthritis.

Objective To discuss wound edge characteristics at different clinical periods and in-tervention of traumatic perforation of tympanic membrane. Methods A total of 494 patients wth trau-matic perforation of tympanic membrane were treated and grouped based on treatment time and size of per-foration. Group A (n = 154, within 12 hours after injury) were treated by residual tympanic membrane repair and gelfoam. Group B (n =149, 12 hours after injury) were treated by simple gelfoam. Group C (n = 116) and Group D (n =75) were treated by conventional therapy. The wound healing of peroration was observed after one month. Results Of all, there were 419 patients with maximum perforation diameter > 2.5 mm within five hours after injury, of which 349 patients (83.3%) were with residual tympanic membrane valgus of perforation rim, 29 (6.9%) with involution of perforation rim and 41 (9.8%) with complete loss of tympanic membrane. Of 75 patients with maximum perforation diameter <2.5 ram, residual valgus of perforation rim was found in 18 (24.0%) and tympanic membrane wrinkle near wound edge in the other patients. Under endoscopic repair of crimp tympanic membrane, maximum perforation diameter was reduced for (6.5±2.5)mm in 143 patients at 6th hour, (6.0±1.5)mm in 11at 7-11 hours, (2.0±1.5) mm in 27 at 13-24 hours, (1.5±1.0) mm in 59 at 25.5-48 hours, (1.0±0.5) mm in 49 at 51-73 hours and 0 mm in 14 at 75-192 hours. The follow up lasted for one month, which showed that healing rate of perforation in groups A, B, C and D were 85.3%, 71.2%, 59.2% and 81.4%, respectively. Healing time span was (10±4) days, (19±4) days, (25±2) days and (16±2) days, respectively. Conclusions Traumatic perforation of tympanic membrane is not com-plete tympanal deletion but residual tympanic membrane valgus of perforation rim,involution and tympanicmembrane crushing, which shows insignificant change with time. In time repair of residual tympanic membrane 12 hours(especially 6 hours) after injury may reduce the largest diameter of perforation and re-markably shorten the healing time of perforation.

OBJECTIVE To investigate the cytotoxic activity of Arca subcrenata Lischke anticancer protein(ASAP)constituents on human myeloid leukemia K562 cells in vitro and analyze its anticancer mechanisms. METHODS ASAP was extracted by low temperature water and ammonium sulfate precipitation. Protein concentration of ASAP was detected by Bradford method. Morphological changes of cultured K562 cells treated with ASAP were observed under the inverted phase-contrast micro?scope. The cell and nucleus changes were analyzed by Giemsa staining. The cytotoxicity of ASAP on K562 cells was detected by MTT assay. Flow cytometry was used to detect apoptosis and cell cycle of K562 cells treated with ASAP. The expression of apoptosis and cell cycle related proteins procaspase 3, caspase 3,P53 and programmed cell death 4(PDCD4)were analyzed by Western blotting. RESULTS ASAP exhibited significant cytotoxic effect on K562 cells in a time- and concentration-dependent manner. The concentration-effect correlation coefficient of ASAP 50,100 and 200 mg · L-1 on K562 cells for 24, 48 and 72 h was 0.851,0.8977 and 0.8997,respectively. Under an optical microscope,K562 cells showed cytomorphosis,or nuclear fragmentation after treatment with ASAP 200 mg · L-1 for 48 h. Flow cytometry analysis and Giemsa staining assay indicated that apoptotic cells increased and G2/M phase cells accumulated significantly with the increase of ASAP concentration. After treatment with ASAP 200 mg · L-1 for 48 h,the early and late apoptosis cell rate increased to(32.8 ± 0.1)%and(31.2 ± 2.2)%vs control group(3.7 ± 1.1)% and (9.9 ± 0.8)%(P<0.01),respectively,and the G2/M phase cells increased to (55.2 ± 1.7)% vs (15.3 ± 0.8)% in control group(P<0.01). After treatment with ASAP 200 mg · L-1 for 0-40 h,the expression of apoptotic protein procaspase 3 was down-regulated and its active form caspase 3 was significantly up-regulated at 32 h,while PDCD4 and P53 protein expression was down-regulated significantly in 0-40 h. CONCLUSION Apoptosis and cell cycle arrest induced in G2/M phase may account for ASAP cytotoxic activity to K562 cells. K562 cell apoptosis induced by ASAP depends on caspase 3 signal pathway. Down-regulated expression of PDCD4 and P53 proteins may be related to K562 cell apoptosis and cell cycle arrest in G2/M phase by ASAP.

Objective To explore the characteristics of EEG frequency in recruits and veterans and their relationship with depression scale scores.Methods Fifty-five newly enlisted soldiers formed the recruits group and 68 demobilized soldiers the veterans group.A general information survey,EEGs and the Hamilton depression scale (HAMD) were administered to all of the subjects.According to the HAMD scores,35 of the 123 were designated as the abnormal group,while 88 formed the normal one.Eighteen of the 35 with EEG abnormalities served as a doubleabnormal group to be compared with the remaining 17 cases with abnormal HAMD scores and normal EEGs (the single-abnormal group),and 9 of the 18 with higher HAMD scores as the higher group,and the other 9 cases as the lower group.The EEG frequency spectrum and the power percentages from the δ to γ frequency bands were calculated as δ:0.5-4 Hz,(o):4-8 Hz,α:8-13 Hz,β:13-25 Hz,γ:25-40 Hz.Results Forty-six of the subjects (37.4％) had abnormal EEG results,35 had abnormal HAMD scores,and 18 (51.4％ of the soldiers with abnormal HAMD scores) had both abnormalities.The veterans had lower δ band power percentage in all channels than the recruits,but in the (0) band it was the reverse.In the left channels the veterans had lower α and γ band power percentages than the recruits.Compared with the normal,all channels in the EEGs of subjects with abnormal HAMD scores had significantly higher δ band power percentages.The higher the δ band power percentage a subject had,the higher his HAMD score.Conclusion There is some correlation between changes in EEG power percentages and the possibility and severity of depression.Objective and subjective EEG evaluation can help improve the positive rate of diagnosis,and thus the management of the army.
