BACKGROUND:Whether there are breast cancer stem cel microspheres in the breast cancer tissues and whether these microspheres have an impact on isolation and culture of breast cancer stem cel s after different cycles of neoadjuvant chemotherapy are stil unclear. OBJECTIVE:To explore the proliferation and differentiation of breast cancer stem cel s in breast cancer tissues after different cycles of neoadjuvant chemotherapy. METHODS:Breast cancer stem cel microspheres were isolated from the breast cancer tissues after different cycles of neoadjuvant chemotherapy to drawn a cel growth curve. Immunocytochemical method was used to detect ALDH1 expression. RESULTS AND CONCLUSION:Microspheres could be obtained from the specimens of neoadjuvant chemotherapy for two, three and four cycles rather than one cycle. At 3 days prior to culture, there was no difference in the number of cel s isolated after two-and three-cycle neoadjuvant chemotherapy;but after 3 days, the cel s from the three-cycle neoadjuvant chemotherapy proliferated faster than those from the two-cycle neoadjuvant chemotherapy;after 6 days, the cel growth curve of two-cycle neoadjuvant chemotherapy was in the plateau stage, and the proliferation of cel s from the three-cycle neoadjuvant chemotherapy showed a rapid increase trend. The positive expression of ALDH1 in the microspheres from the three-cycle neoadjuvant chemotherapy was higher than that from the two-cycle neoadjuvant chemotherapy. These findings indicate that breast cancer stem cel s from the specimens of two-and three-cycle neoadjuvant chemotherapy both have proliferation and differentiation potentials, and the specimens of three-cycle neoadjuvant chemotherapy or above are preferred.

Objective To explore the correlation between obstructive sleep apnea syndrome(OSAS)and developing hypertension.Methods Clinical data of 124 OSAS patieats with high blood pressure were retrospectirely,and according to the degree of hypoxemia they weredivided into three groups,monitoring of the night and 7h polysomnography figure,compare each group,woke up blood pressure changes before bedtime.Results 124 patients with hypertension OSAS clinical manifestation:snoring 124 cases(100.0％),daytime sleepiness 74 cases(59.7％),wake up in the night to suppress 49 cases(39.5％),night apnea 39 cases(31.5％),woke up oppressed 26 patients (21.0％),since morning headache 19 patients(15.3％).OSAS merger hypertension,light,medium,heavy hypoxemia between groups of blood pressure,blood pressure after come before a statistically significant difference(P ＞0.05).Conclusion Hypoxia was associated with high blood pressure.

Objectives To examine clinical characteristics,predisposing factors,treatment and care of depression and/or anxiety symptoms in hospitalized patients with cardiovascular diseases.Methods A retrospective analysis of clinical data of 1 005 hospitalized patients with cardiovascular diseases at our hospital from January 2015 to December 2015 was conducted and psychological assessment for all patients was carried out using the Hamilton Anxiety Rating Scale and the Hamilton Depression Rating Scale.The incidence of depression and anxiety and predisposing factors were investigated.The effectiveness of psychological intervention in addition to cardiovascular medications was evaluated.Results The overall incidence of depression and anxiety was 23.4％ (235 cases) among the 1 005 hospitalized patients with cardiovascular diseases.Of the 235 cases,73 cases(31.1％) had anxiety,33 cases had depression (14.0％),and 129 cases had both anxiety and depression (54.9％).The occurrence of anxiety was significantly higher than that of depression(P＜0.05).Risk factors for anxiety and depression in patients with cardiovascular diseases included work-related fatigue,working conditions and health status.The rate of effectiveness of psychological intervention was 95.4％,and no serious adverse events were observed.Conclusions Depression and anxiety are common in hospitalized cardiovascular patients and can be attributed to factors such as work-related fatigue,working conditions and health status.Favorable clinical outcomes can be achieved through psychological interventions,in addition to cardiovascular drug therapy.

Investigate the effect of prestorage white cell filtration on the cytokines content in blood. Methods: Ten units of whole blood was divided into two parts just after blood collection:one was used as control, the other was filtrated by leukoreduction filters. All units were stored at 4℃ for 6 weeks. Immediately after filtration and every week subsequently, samples for analses of IL-2, IL-8 were obtained. Results:The amounts of IL-2 and IL-8 increased during the storage period. In filtered units, the amounts of IL-8 did not increase during the study period, IL-2 still increased but was still lower than that of unfiltered units at the end of storage. Conclusion: Many cytokines, such as IL-2 and IL-8, were generated and accumulated in blood during blood storage. Leukocyte filtration may prevent this effect to some extend. Prestorage filtration may decrease FNHTRs by preventing the accumulation of cytokines in blood.

Objective To study the effect of leukoreduction transfusion on improving medical quality. Methods The cases in our hospital which had RBC transfusion records in the past 3 years were collected and divided into two groups: leukoreduction group(LR) and non-leukoreduction group(NLR). Through statistical analysis, the items related to leukoreduction were found out and the differences in these items between the two groups were compared. Results Operation complication, non-operation complication, infectious rate, transfusion reactions and mortality rate in LR group were significantly lower than those in NLR group. The transfusion of single components-RBC had less clinical side-effect than the transfusion of complex components including RBC. Conclusions Leukoreduction transfusion can effectively improve clinical therapy and promote the medical quality.

Objective To study the changes of CPDA whole blood's shelf life after stored at non-4℃. Methods 200 ml whole blood was collected from each of 10 donors and anticoagulated by CPDA. Then 50 ml whole blood from each one was marked as control group, the rest was marked as test group. The blood of the control group was stored at 4℃ and RBC ATP concentration at the end of its shelf life served as critical ATP. The blood of the test group was stored at 10℃ for 24 hours, then it was transferred to 4℃ refrigeratory and continued to preserve. RBC ATP concentration were tested daily to ensure it eligible. When RBC ATP concentration decreased to the level of critical ATP, the time of preservation at 4℃ was blood's succeeding shelf life. Using the same method, the succeeding shelf life of CPDA whole blood after stored at different temperature for 48 to 72 hours was measured. Results The succeeding shelf life of CPDA whole blood did not obviously change after stored at non-4℃ for 24 hours, while it shortened dramaticly after stored at non-4℃ for more than 48 hours. The higher the temperature, the shorter the succeeding shelf life. Conclusion The results suggested that CPDA whole blood's succeeding shelf life should be adjusted after stored at non-4℃ for 24 to 72 hours to ensure the blood quality.

Objective To prolong the shelf life of RBCs stored at non-4℃, and improve the ability of blood supplying during wartime. Methods 12 bags of packed RBC were collected from 12 volunteers presenting blood, respectively, and each was averagely divided into 5 parts(groups): combination group, new solution group, ammonia group, control group and 4℃ group. The fist 4 groups were stored at room temperature, and were tested for ATP concentration daily. 4℃ group was stored at 4℃, and RBC ATP concentration was measured at the end of its shelf life, which served as a critical ATP concentration. When RBC ATP concentration of the fist 4 groups decreased to the level of critical ATP, the time of preservation was their shelf life. 6 bags of packed RBC were added the same solution as the combination group, and each was averagely divided into 4 parts(groups)after stored at room temperature for 12 days, which were washed for 0, 5,10 and 15min before centrifugation, respectively. The residual ammonia and the recovery ratio of RBC were measured after washing. Results The shelf life of combination group,new solution group,ammonia group and control group was 12,6,6 and 5 days, respectively. The residual ammonia could be effectively cleaned up after either washing 4 times with 5 min balance time or 3 times with 10 or 15 min balance time. The recovery ratio of RBC was 88.5% and 83.1% after washing 3 and 4 times, respectively. Conclusion The combination of new solution and ammonia was a good additive solution for RBC preservation at non-4℃, and the residual ammonia can be cleaned up using normal saline.

Objective To study the preservative indices of stored platelet and verify the effect of a new platelet incubator made in China. Methods 12 bags of fresh platelet rich plasma (PRP) were collected. Each bag was equally divided into 2.One bag was stored for 5 days in XHZ-IA platelet incubator which was made in China, and the other bag stored in FORMA-3606 platelet incubator made in USA. Some preservative indices of stored platelet e.g. aggregation rate, recovery rate after response to hypotonic shock, CD62p expression rate etc. were tested daily. Results There were no significant differences in these preservative indices between platelets stored in two platelet incubatorshas. Conclusion XHZ-IA platelet incubator has the same effect on PRP preservation as FORMA-3606 platelet incubator.

Objective To retrospectively analyse the impact of imatinib mesylate(Gleevec)on HSCT outcome in patients with Ph(+)leukemias.Methods From June 2001 to June 2005,31 CML-BC/AP patients and 8 refractory Ph(+)ALL patients were treated with imatinib mesylate to induce remission,followed by allogeneic transplantation,and we evaluated its influence on engraftment,graft versus host disease(GVHD),overall survival(OS),disease free survival(DFS),relapse rate(RR)and transplant-related mortality(TRM).Results Eighteen of 39 patients achieved complete hematologic remission(CHR),9 patients bone marrow remission(BMR)and 4 patients partial response(PR),the overall response rate being 70.96%.After HSCT,all patients achieved complete allogeneic engraftment with a median of 14 and 13.5 days for neutrophil and platelet recovery,respectively.The cumulative incidence rates of Ⅱ~Ⅳ? and Ⅲ~Ⅳ? aGVHD were 61.53% and 15.38%.The probability of OS and DFS was(73.51?9.61)% and(61.28?12.37)%,when HSCT was performed in CR,compared with(36.36?14.50)% and(31.25?13.98)% in NR.The 3-year cumulative relapse rate(RR)was 20.41% vs 75.00%.Four cases died of transplant-related complications.Conclusion Pre-transplant imatinib mesylate seems effective and safe for refractory Ph(+)leukemias;it allows transplantation to be in a more favorable status,and leads to better outcome.
