Objective To explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.

AIM: To observe the effect of Qingluo Tongbi Granule(QLTBG)——containing serum on the proliferation of osteoblasts(OB) and osteoclasts(OC),the activity of AKP of OB. METHODS: (1) OB were separated from the skull of SD rats aged 1 d and OC from the thighbone and shinbone of SD rats aged 5 d.(2) The proliferation of OB and OC was detected by MTT method,and the activity of AKP of OB was examined by diazol method. RESULTS: The proliferation capability of OB was strengthened markedly by the rat sera containing 7.2,14.4 g/kg QLTBG,which could reinforce the activity of AKP obviously as well,while the proliferation of OB was inhibited remarkably by the rat sera containing 3.6,7.2,14.4 g/kg QLT. CONCLUSION: The sera containing QLTBG could enhance the proliferation of OB and the activity of AKP,restrain the proliferation of OC simultaneously.

Objective To retrospectively analyze the influence of perioperatively transfusing different ratios of fresh frozen plasma (FFP) to red blood cell (RBC) on prognosis of patients receiving massive transfusion.Methods From January 2010 to September 2012,139 surgical patients with transfusion of ≥ 10 RBC units within 24 hours were included in the study.Patients were categorised into three groups based on the FFP ∶ RBC scale:high scale group (FFP ∶ RBC ＞ 1 ∶ 1,n =19),middle scale group (FFP ∶ RBC =1 ∶ 2-1 ∶ 1,n =43) and low scale group (FFP ∶ RBC ＜ 1 ∶ 2,n =77).Comparison among the groups was made in aspects of transfusion of different blood products in hospital,blood routine index before and after massive transfusion,blood coagulation index,electrolyte index,hospital stay,ICU stay,cure rate and mortality.Results FFP transfusion was the most in high scale group (2 600 ± 1 582) ml,followed by (1 390 ± 1 043) ml in middle scale group and (318 ± 342) ml in low scale group (P ＜0.05).Platelet (PLT) transfusion was more in high scale group (0-1.4 units) and middle scale group (0-1.0 units) compared with that in low scale group (0-0.0 units,P ＜ 0.05).Volume of RBC and cryoprecipitate transfused revealed no significant differences among the groups (P ＞ 0.05).Before blood transfusion prothrombin time (PT) [(20.2 ± 10.7) s] and activated partial thromboplastin time (APTT) [(57.2±45.8) s] in middle scale group were significantly prolonged than those in high scale group [(14.3 ±4.4) s and (35.3 ± 10.0) s] and low scale group[(12.5 ± 1.7) s and (31.5 ± 5.9) s] (P ＜ 0.05),but the differences were insignificant in indices of hemoglobin (Hb),PLT,international normalized ratio (INR),K +,and Ca2 + (P ＞ 0.05).After blood transfusion Hb [(106.8 ± 31.7) g/L] and Ca2+[(1.99 ± 0.24)mmol/L] in low scale group were higher than these in middle scale group [(82.5 ± 32.2) g/L and (1.76 ± 0.38) mmol/L] and in high scale group [(91.3 ± 19.1) g/L and (1.96 ±0.25) mmol/L] (P ＜0.05),but there were no significant differences in PLT,PT,INR,APTT and K+(P ＞ 0.05).Moreover,hospital stay,ICU stay,cure rate and mortality were not differed significantly among the groups (P ＞ 0.05).Conclusion For massive transfusion patients,transfusion of FFP and RBC at a 1 ∶ 2 to 1 ∶ 1 ratio is beneficial to preventing coagulation dysfunction and reducing plasma total infusion volume,and exerts no effect on the prognosis.

Background Researches determined that the pathogenesis of retinal vein occlusion (RVO) is associated with primary open angle glaucoma (POAG) in Caucasian population.However,the relationship between RVO and POAG in Asian population is unclear.Objective This study was to survey the percentage of POAG in RVO patients in China.Methods A prospective cross-sectional observational study based on hospital was performed.Three hundred and seventy five patients with newly diagnosed RVO by fluorescein fundus angiography (FFA) were consecutively enrolled in Peking University Third Hospital from October 2011 to May 2013,and gonioscopy was carried out in all the patients.Glaucoma was diagnosed according to the criteria of the International Society of Geographical and Epidemiological Ophthalmology (ISGEO).RVO was classified into central retinal vein occlusion (CRVO),hemicentral retinal vein occlusion (HRVO) and branch retinal vein occlusion (BRVO) based on fundus photograph and FFA,or classified into arteriovenous crossing RVO (AV-RVO),optic cup RVO (OC-RVO),optic nerve RVO without optical nerve head swelling (NONHS-RVO) and RVO with optical nerve head swelling (ONHS-RVO) based on the sites of venous occlusion.The percentages of POAG in different types of RVO were calculated.This study was approved by Ethic Committee of Peking University Third Hospital,and written informed consent was obtained from each patient before entering study cohort.Results Three hundred and seventeen RVO patients finished screening of glaucoma,with the response rate 84.5％.The percentage of POAG is 8.2％ in RVO patients,including 7.1％ in the CRVO patients,23.5％ in HRVO patients and 6.2％ in BRVO patients.The percentage of POAG was significantly higher in OC-RVO patients (27.9％) and NONHS-RVO patients (13.2％) than that in AV-RVO patients (4.7％) and ONHS-RVO patients (1.3％) (all at P＜0.05).Conclusions The overall percentage of POAG in RVO patients in China is 3-4 times higher than general population.Higher percentage of POAG is found in OC-RVO patients and NONHS-RVO patients,suggesting that pathogenesis of RVO is probably associated with the glaucomatous anatomic changes of optical nerve head.

Objective:To analyze the effects of protein intake of varied dietaries on the pregnancy of pregnant women.Methods:The pregnant women who had their medical records in our hospital were included in this study.Their dietary were collected based on the respective review of their food during 24 hours when they visited the Nutrition Clinics between 24 weeks and 28 weeks.The subjects were divided into six groups according to the dietary calories and protein intake:group A (normal calorie and normal protein),group B (normal calorie and low protein),group C (normal calorie and high protein),group D (high calorie and normal protein),group E (high calorie and high protein) and group F (low calorie and low protein).The gestational diabetes mellitus incidence rates,levels of fasting blood glucose (FBG),blood glucose (BG),hemoglobin Alc (HbAlc),and blood lipids,and bone mineral density were compared among six groups.Results:The gestational diabetes mellitus incidence rate,levels of postprandial blood glucose at 1 hour and 2 hour in groups of B,C,D,and E were significantly higher than those in group A (P ＜ 0.05).The levels of triglyceride,total cholesterol,and low density lipoprotein cholesterol were remarkably higher in groups of B,D,and E than those in group A (P ＜ 0.05).The bone mineral density was significantly lower in group A than that in groups of C,E,and F (P ＜ 0.05).Conclusion:The diet with normal calorie and normal protein is the scientific dietary structure.The pattern with high calorie and high protein intake is not recommended for pregnant women.

AIM:To investigate the expression of aplasia rashomolog member I ( ARHI) gene in acute myeloid leukemia cells (AML) and to study the effects of ARHI on the growth of AML cell line U937.METHODS:The mRNA ex-pression of ARHI in AML cells, 293FT cells, AML primary cells and healthy volunteer blood cells were detected by RT-PCR.After transfection with the MSCV-IRES-GFP-ARHI plasmid to the U937 cells, the growth curve was analyzed by MTT assay.U937 cells were re-suspended by fresh medium and cultured for 24 h, then the cell cycle distribution and ap-optotic rate were determined.RESULTS:The mRNA of ARHI was positively detectable in 293FT cells and healthy volun-teer blood cells instead of AML cell line and AML primary cells.The growth curve showed that cell viability in U937 cells with high expression of ARHI (U937-ARHI) was lower than that in the control cells (U937-GFP) on 6th~8th day.The ratio of G2/M phase and apoptotic rate in the U937-ARHI cells were increased compare with control group ( P<0.05 ) . CONCLUSION:The mRNA level of ARHI is low in AML cells.High expression of ARHI gene in U937 cells inhibits cell growth, arrests the cells at G2/M phase and induces apoptosis.
