Objective To explore the effect of follow-up by telephone calls on the medication compliance of patients with cancer pain.Methods Two hundred and forty hospitalized cancer patients suffering from moderate to severe cancer pain were included in the study. All the patients were provided with education on pain treatment before discharge.Then they were randomly assigned to receive telephone follow-up or routine nursing after discharge.The medication compliance were compared 2 months after discharge.Result The medication compliance in the observation group was significantly better than that in the control group.Conclusion Telephone follow-ups can improve medication compliance in patients with cancer pain.

Objective To study the influencing factors of occupational musculoskeletal injuries(OMSI)in nurses from operation room.Method By convenience sampling,300 nurses from the operation rooms of 8 First Class Grade A hospitals in Shenzhen were involved in the study.Results The age for first onset of OMSI in the nurses was(31.6±6.8)years,with a prevalence rate of 81.3%.The back,waist and shoulder were the most vulnerable for their highest prevalence.The influencing factors included age,seniority,overweight,lack of resting time,lack of notice of muscle relaxation and physical exercise and inadequacy of post shifting.Conclusions The prevalence of OMSI in nurses from operation rooms is higher.Besides age,seniority and BMI,it is closely related with occupational risk factors and occupational management factors.

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 study the influence of Chiamydia trachmatis (CT) and Ureaplasma ure-alyticum (UU) infection on pregnant outcome and neonates. Methods 562 pregnant women were ran-domly selected, their cervical secretion was collected and detected for CT and UU by culture method. Groups were divided according to the results. All of them were followed-up till delivery. Results The in-cidence of infection of group CT、group UU、group CT and UU were 22.1%、28.8% and 3.7%;Compared with negative group,the group with positive result of CT、UU、 CT and UU had significant higher incidence of preterm labor, premature rupture of membranes, low weight infant and neonates pneumonia. Conclusions The infection of CT、UU can result in adverse pregnant outcome, preterm labor, premature rupture of mem-branes, low weight infant and neonate pneumonia.

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.

Objective To study the relation between the levels of protein C(PC),protein S(PS),antithrombin Ⅲ(AT-Ⅲ)with cerebral infarction.Methods 126 patients with cerebral infarction were divided into the groups according to the age,onset time and infarction area and contemporaneous 30 individuals with healthy physical examination were selected as the control group.The levels of PC,PS and AT-Ⅲ were detected.The relation between the change of these indicator levels with the age,onset time and infarction area was analyzed Results The levels of AT-Ⅲ,PC and PS in the acute stage youth group were lower than those in the acute stage middle age and elderly group with statistical differences between them (P <0.05).The level of the AT-Ⅲ,PC and PS in the acute stage group were lower than those in the recovery stage group and the control group,difference had statistical significance(P <0.05).The levels of AT-Ⅲ and PS in the recovery stage group were lower than those in the control group with statistical difference (P <0.05),but the level of PC had no statistical difference between the recovery stage group and the control group.The further study found that the level of AT-Ⅲ,PC and PS in the small infarction group,middle infarction group and large infarction group showed the gradually decreasing trend,the differences had statistical significance (P <0.05).Conclusion The decrease of AT-Ⅲ, PC and PS levels is the importan factor of cerebral infarction occurrence and is closely correlated with cerebral infarction ocurrence especially in the patients less than 45 years old.Observing the change of PC,PS and AT-Ⅲ levels has the important significance for judging the cerebral infarction progression.

Objective To investigate the effect of diet and gene on blood-fat trait of the individual.Method One hundred and twenty mice were fed with high fat emulsion for 4 w,then the genotypes of LPL were analyzed by PCR-SSCP to investigate their effect on blood-fat traits and some organ performance of mice.Result After fed with high fat emulsion for 4 w,98 mice suffered from hyperlipidemia,while 22 mice did not.And a G/A mutation was found in 220 targeted fragments we amplified at 14355 site,and association analysis showed that the mice with BB genotype had higher TC、TG、LDL、H/W、L/W level than those of the mice with AA genotype(P

Aim Establish a novel mouse model of airway goblet cell hyperplasia and mucus hypersecretion.Method BALB/c mice were sensitized subcutaneously with ovalbumin(OVA) allergens in aluminium hydroxide at d 0,re-sensitized once intraperitoneally d 10 after first sensitization,and challenged with OVA aerosolly daliy from d 15 to d 21 after first sensitization.Inflammatory cell number in BALF,eosinophil infiltration in the lung tissue with HE stain and goblet cells in the bronchial mucous membrane with PAS stain were examined.Dexamethasone was employed to validate the model.Results Mice sensitized and challenged with OVA showed a significantly hyperplasia of goblet cells in the bronchial mucous membrane,increased mucus in the alveolar cavity,eosinophil infiltration in the lung tissue and increased number of inflammatory cells in BALF.Those pathological changes were inhibited by dexamethasone and mIL-2 plasmid.Conclusion This model helps to screen the new drugs for mucus hypersecretion and research on the pathological mechanism of airway mucus hypersecretion.
