A total of 120 medical students were surveyed to investigate the current status of communication between medical students and old patients and the awareness of medical laws. The questionnaire shows many students don't have enough knowledge of communication skills and medical laws. Furthermore, the most important reason of the medical disputes is the lack of communication between doctors and patients so the cultivation of communication skills and legal knowledge should be strengthened.

Objective:To observe the stability of thymosin ?_1 microspheres under preparation conditions.Methods: Using HPLC method,we investigated the influence of different temperatures(-20 ℃, 6-8℃,60℃),sonification time(10-60 s) and pH values (pH 4.0,7.0 and 10.0) on thymosin ?_1 stability.Results: Under the conditions of frozen environment(-20℃) and refrigeration(6-8℃), thymosin ?_1 remained stable for 30 d.Thymosin ?_1 did not degrade in 60℃ water bath for 12 h or in phosphate buffer solution(PBS,pH 4.0) under 37℃ for 14 h.The sonification time within 60 s was found to be safe for the preparation.Conclusion: Thymosin ?_1 is stable under these preparation conditions.

Objective To investigate the relationship between post-stroke pathological laughing and crying and depression.Methods Among 276 stroke patients in hospital,28 patients with pathological laughing and crying were chosen as PLC group,and other 28 patients matched with gender and age but without PLC were choosen as the control group.All patients were investigated with Hamilton Depression Scale(HAMD),PLC scale and clinical features.Results There was no significantly difference(P>0.05)in total and factor scores of HAMD between these two groups.Conclusion The pathological laughing and crying and depression seem to result from different pathogenesis.

Objective We tried to investigate the nutritional status and related factors in patients undergoing allogenetic hematopoietic stem cell transplantation.Methods A total of 75 patients were recruited from a class-three hospital in Suzhou.They were investigated with a basic information questionnaire and the Patient-Generated-Subjective Global Assessment (PG-SGA).The related factors influencing nutritional status were analyzed.Results The PAB level began to rise since conditioningregimen,and it rose to the highest level in the second week,then began to decline.The weight and the BMI had been declining in the four weeks since conditioning regimen.29.33％ of the patients were malnourished,the scored PG-SGA was (5.60±4.96),the percentage of patients with dietary problems was 33.3％ before conditioning regimen; 85.33％ of the patients were malnourished,the scored PG-SGA was (19.26±7.18),the percentage of patients with dietary problems was 93.2％ in the second week since conditioning regimen; 85.33％ of the patients were malnourished,the scored PG-SGA was (12.95±6.19),the percentage of patients with dietary problems was 75.8％ in the fourth week; Age is the main factor affecting the patients' albumin level in the second week.Conclusions The nutritional status of patients deteriorated and the percentage of patients with malnutrition increased during allogeneic hematopoietic stem cell transplantation.Clinical staff should pay attention to the assessment of nutritional status,and give a reasonable nutritional support when necessary.

Objectives: To explore the relationship between vascular active peptide, apelin level and blood pressure in a coastal population of Fujian province.
Methods: A total of 1031 subjects with the mean age of (55.1 ± 10.9) years in a coastal area of Fujian province were included in this cross-sectional study, and 416 subjects with male gender. The questionnaire survey, physical examination and plasma level of apelin measurement were conducted. Based on JNC-7 deifnition of hypertension, the subjects were divided into 3 groups: ① Hypertension group, the patients with systolic blood pressure (SBP)≥140 mmHg and/or diastolic blood pressure (DBP)≥90 mmHg, n=496. ② Pre-hypertension group, SBP at (120-139) mmHg and/or DBP at (80-89) mmHg without medication, n=314.③Normal BP group, SBP<120mmHg and DBP<80mmHg without medication, n=221. Based on 4 quartiles of apelin levels, the subjects were further divided into 4 groups:Q1 group, apelin<164.8 ng/ml, n=258. Q2 group, apelin at (164.8-<220.0) ng/ml, n=258. Q3 group, apelin at (220.0-283.1) ng/ml, n=258. Q4 group, apelin>283.1 ng/ml, n=257. One way analysis of variance, covariance analysis and multivariate linear regression analysis were used to study the
relationship between apelin level and BP.
Results: The apelin level in male gender (220.57 ± 78.87) pg/ml was lower than female gender (232.06 ± 81.17) pg/ml. Compared with Normal group, Pre-hypertension group had decreased apelin level, compared with Normal and Pre-hypertension groups, Hypertension group had decreased apelin level, P<0.05. Compared with Q1 group, Q2, Q3 groups presented decreased SBP, DBP and mean arterial blood pressure (MABP), and compared with other 3 groups, Q4 group had decreased SBP, DBP (not including Q2, Q3 groups) and MABP, P<0.05. With adjusted age and gender, SBP, DBP and MABP were signiifcantly different among 4 quartiles of apelin groups, P<0.05. Multivariate linear regression analysis indicated that SBP, DBP and MABP were negatively related to apelin level, such relationship remained the same after adjusting the other cardiovascular risk factors.
Conclusion: Apelin level dropping accompanying with BP increasing implies that vascular active peptide, apelin involved in BP regulation.

Objective To evaluate the effect of haploidentical lymphocyte infusion on refractory and relapse acute leukemia. Methods The haploidentical donor lymphocyte infusion was used to treat for relapse acute myeloid leukemia 3 patients (M2 2 eases, M4 lcase), one relapse acute lymphocyte leukemia from April 2006 to October 2007. Four cases who had accepted secondly regimens were ineffective,after relapse. Collecting donor lymphocytes, parents children as donor supply in 3 cases, mother as donor supply one case. Before donor lymphocyte infusion patients received chemotherapy of different regimens. Donor haploidentical iymphocytes irradiated by 6-8 Gy radial were infused when patients white cell count was at the lowest after the chemotherapy. The average of infusion cells was 2.3 (1.4-3.1)×108/kg. Results One patient acquired complete remission and two patients were effective in three relapse acute myeloid leukemia. It was ineffective in relapse acute lymphocyte leukemia. No transfusion related graft versus host disease was observed. One patient has had herpes zoster virus infection. Conclusion Haploidentical donor lymphocyte infusion with chemotherapy are effective for refractory and relapse in acute myeloid leukemia, but the infused cell quantity and irradiated dosage must be further discussed.

BACKGROUND: Previous studies have shown that HLA-identical sibling allogeneic peripheral blood hematopoietic stemcelltransplantation (allo-HSCT) provides higher disease-free and overall survival rates for patients with intermediatecytogenetic risk acute myeloid leukemia (AML) in complete remission (CR). But prognosis factors have not been fullydefined.OBJECTIVE: To evaluate the outcome of patients with intermediate cytogenetic risk AML undergoing HLA-matchedallo-HSCT in CR, and to analyze the prognostic factors.METHODS: Fifty cases of intermediate cytogenetic risk AML in CR receiving HLA-matched allo-HSCT from January2009 to January 2015 were retrospectively analyzed. Primary outcome measures of the study included overall survival(OS), relapse rate and non-relapse mortality.RESULTS AND CONCLUSION: The 4-year OS of the study population reached to 64%, and the relapse rate and NRMreached to 18% and 20% respectively. Incidence of acute graft-versus-host disease was 26%. Different prognosis wasobserved between female donor/male recipient (FDMR) combination transplant and control (4-year OS: 50% vs. 71.9%,P=0.041), between patients requiring more than one course of induction chemotherapy to achieve CR and control(4-year OS: 40% vs. 70%, P=0.038), between older age (≥ 40 years) and control (4-year OS: 44.4% vs. 68.3%,P=0.056). The 4-year OS for matched sibling donor and matched unrelated donor was 63.2% and 66.7% (P=0.427),respectively. Further analysis revealed significantly high non-relapse mortality in FDMR combination transplant (P=0.024)and older age (≥ 40 years; P=0.043). Multivariate analysis revealed three negative prognostic factors: FDMRcombination (P=0.031, RR=1.38, 95% CI: 1.03-1.95), requiring more than one course of induction chemotherapy toachieve CR (P=0.016, RR=1.46, 95% CI: 1.10-1.98) and older age (≥ 40 years; P=0.024, RR=1.63, 95% CI: 1.32-2.12).To conclude, HLA-matched allo-HSCT is a choice for the intermediate cytogenetic risk AML case in CR. FDMRcombination, requiring more than one course of induction chemotherapy to achieve CR and older age (≥ 40 years) areconfirmed as risk factors of poor prognosis for HLA-matched allo-HSCT patients with intermediate cytogenetic risk AMLin CR. To these cases, the donor-recipient sex combination is more important than the donor type in donor selection.

Objective To evaluate the gene mutation of RANTES and CCR5 in SLE and its significance. Methods One hundred and forty-six definitive SLE patients and 159 controls were collected. SNPs of RANTES promoter and polymorphism of CCR5 were performed by PCR or PCR/RFLP assay, and further confirmed by direct DNA sequencing. Results The frequence of RANTES-403G/G compounded with 28C/C and CCR5/CCR5 was significantly different between SLE and control groups (72.6% vs 58.5%, P 0.05). Conclusions These results indicate that the two SNPs are linkage disequilibrium. Interaction of two SNPs in RANTES and CCR5 is related with SLE. RANTES-403G/G compounded with 28C/C and CCR5/CCR5 may be one of risk factors of SLE. RANTES-403A is probably related with renal damage of SLE.

Objective To retrospectively review and compare the clinical results of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from HLA- matched sibling donors mobilized with different regimens. Methods Seventy-one patients with hematological malignant diseases received allo-PBSCT from HLA-matched sibling donors in our department. Among them, 24 received allografts mobilized with G-CSF (group G), and the remaining (47 cases) were mobilized with G-CSF and GM-CSF (group G+ M). CD34+ subsets and T cell subsets in the allografts were analyzed, and the time of hematopoietic reconstitution and the incidence of graft versus host diseases (GVHD) were compared. The adverse effects on the donors after mobilization were also observed. Results The enough targeted CD34+ cells in all donors were harvested by 1-3 aphereses. Ninety-six h after mobilization, WBC counts of the donors were significantly higher in group G than in group G + M [(49. 6± 19. 5) 109/L vs (25.4 ± 10. 4) 109/L, P＜0. 05]. Analysis of the CD34+ subsets showed that the percentage of cells with the CD34+/CD38- phenotype was significantly higher in group G + M than in group G [(37. 7 ± 5. 7) % vs (31.4 ± 4. 5) %, P＜0. 05]. There was no significant difference in T cells and subsets of grafts. There was no significant difference in the number of total CD34+ cells and CD34+ CD38- cells, and infusion of T cells between two groups. The days required for the recovery of neutrophils and platelets was inversely correlated with the infused CD34+ and CD34+ /CD38- cell number. There was no significant difference in incidence of acute and chronic GVHD between two recipient groups. Seventeen cases and 10 eases among 71 eases died of relapses of primarydiseases, and complications of transplantation such as severe GVHD and infections respectively.Fourteen cases in group G (58.3 %) and 31 cases in group G+ M (66.0 %) survived. The most common adverse events in the donors were bone pain and fever, which mostly occurred 36 h after mobilization and could be relieved by non-steroidal anti-inflammatory drugs. Conclusion Two mobilization regimens showed equivalent clinical results. But the combined regimen of G-CSF and GM-CSF demonstrated a significantly greater mobilization of cells with the CD34+/CD38- phenotype.Meanwhile in allogeneic PBSCT, a greater number of total CD34+ cells and CD34+ CD38- cells infused may be associated with faster hematopoietic reconstitution of recipients.
