Objective To investigate the relationship between hypertensive disorder complicating pregnancy(HDCP)with homo-cysteine,D-D and high sensitive C-reactive protein(hs-CRP).Methods 80 HDCP women included 38 cases of gestational hyperten-sion,26 cases of mild preeclampsia and 16 cases of severe preeclampsias,and at the same time 36 normal late-term pregnant women and 30 non-pregnant normal women were selected as the control group.The plasma Hcy was determined by the enzymatic cycling assay,D-D was determined by the latex immune turbidimetry and hs-CRP was determined by the nephelometry immuno assay,re-spectively.Results The plasma Hcy,D-D and hs-CRP levels in the HDCP group were significantly increased compared with the normal non-pregnancy women group and the normal late-term pregnancy women group controls and showed the increasing trend with the aggravation of disease condition,the differences had the statistical significance(P <0.01).Conclusion Timely monitoring the plasma Hcy,D-D and hs-CRP levels can effective conduct the adverse pregnancy prediction,thus timely takes the medication in-tervention for correcting the occurrence and development of the disease condition,and provides the significant reference indexes for evaluating the change and prognosis of the disease condition in clinic.

Allogeneic stem cell transplantation is the only treatment which may cure multiple myeloma (MM).The high transplantation related mortality (TRM) limits the wide clinical application of myeloablative allogeneic stem cell transplantation.Non-myeloablative allogeneic stem cell transplantation can reduce the TRM,but the risk of relapse and progress of the disease may get increased. Autononmyeloablative allogeneic stem cell tandem transplantation can reduce both the TRM and the relapse and progress of the disease. At present,there exist many new methods which may improve the effect of allogeneic stem cell transplantation for MM in clinical.

Objective To investigate the role of thrombelastography(TEG) in assessing the risk of bleeding and diagnostic value in patients with acute leukemia(AL) .Methods The TEG and PLT data were counted in 127 patients(272 sets of data) who were diagnosed with AL .Those patients were divided into two groups :group 1 (including patients with bleeding) and group 2 (in‐cluding patients with no bleeding) .The indicators(R values ,K values ,α‐angle ,MA values)and PLT count were compared between two groups .Those data with PLT<30 × 109/L of these two groups also were divided and the 4 indicators of TEG were compared between the two groups .We used the ROC curve to evaluate the sensitivity and specificity in assessing the risk of bleeding .Results According to the data in total ,the K value ,R value of the group 1 were higher than those of the group 2(P<0 .05);theα‐angle and MA value ,PLT counts of group 1 were lower than those of the group 2(P<0 .05) .In those AL patients whose PLT<30 × 109/L ,the K value of the group 1 was higher than that of the group 2(P<0 .05);theα‐Angle and MA value of the group 1 were lower than those of the group 2(P<0 .05);R values and PLT count were not different between the two groups(P>0 .05);the are‐as under the ROC curve about the PLT counts ,MA value andα‐angle were more than 0 .5 (0 .750 ,0 .740 and 0 .653) .Conclusion T EG could predict the risk of bleeding in acute leukemia patients and it could be used in clinical application .

Objective To understand the prevalence and distribution features of mild cognitive impairment(MCI)among elderly in Xinjiang Uygur and Han ethnic groups so as to provide evidence for etiological study and prevention. Methods From July 2007 to October 2008, according to the criteria of DSM-IV for MCI,a randomized, stratified and cluster sampling procedure was used in the Uygur and Han elder people aged ≥60 years in south Xinjiang, east Xinjiang and Urumchi region. Results A total of 2986 people were surveyed, including 1519 Uygur people and 1467 Han people, and 1435 males and 1551 females. (1) According to the age composition of national census in 2000, the total crude prevalence rate of MCI was 10.21%, and the total standardized prevalence rate of MCI was 10.58% in Uygur and Han elder people. In general Uygur and Han population, the crude prevalence rates of MCI were 9.61% and 10.84%, and the standardized prevalence rates of MCI were 10.29%and 10.86%, respectively. The prevalence of MCI was higher in Han population than in Uygur population, but there was no statistical difference(χ~2 = 1.225, P>0.05). (2) In males and females, the crude prevalence rates of MCI were 9.34% and 11.03%, and the standardized prevalence rates of MCI were 9.26% and 11.62%, respectively. There was no difference in prevalence rate between different sex populations(χ~2 =2.314,P>0.05). (3) In elder people aged 60～69, 70～79 and≥80 years, the MCI prevalence rates were 6.83%, 13.22% and 22.22% in Uygur population and 8.64%, 12.50% and 19.30% in Han population, respectively, and the prevalence rate of MCI was increased with aging in the two thnic roups(χ_(for trend)~2=34.753, 14.081, both P<0.05). (4)There were statistical differences in prevalence rates of MCI among different education levels, and it was decreased with enhancement of education levels in Uygur and Han population(χ_(for trend) = 14.785, 21.059, both P<0.05). Conclusions In Xinjiang Uygur and Han ethnic elderly people, the prevalence rates of MCI are significantly different among elderly with different ages and education levels, and it is increased with aging, but is decreased with enhancement of education levels.

Objective To investigate the status of nutritional risk and nutritional support in general surgery patients, and to explore their association with postoperative complications and length of hospital stay.Methods From January 2014 to February 2015, 853 inpatients in general surgical wards in the Second Hospital of Hebei Medical University were enrolled.Nutritional Risk Screening 2002 (NRS 2002) was used to estimate nutritional status of patients.The patients were divided into 2 groups based on whether they received nutritional support.The length of hospital stay in days and postoperative complications were recorded.The association of nutritional risk and nutritional support with complications and length of hospital stay were analyzed.Results In the 853 surgery patients, the prevalence of nutritional risk was 31.1％ (265/853) and that of malnutrition was 5.4％ (46/853).The incidence of postoperative complications was 14.2％ (121/853).The patients with nutritional risk had a significantly higher incidence of postoperative complications compared to those without nutritional risk [29.8％ (79/265) vs.7.1％ (42/588) , P ＜ 0.000] , and a longer hospital stay [(12.5 ±6.4) days vs.(4.2 ±3.9) days, P ＜0.001].In the 853 patients, 27.3％ (233/853) received nutrition support.In the patients with nutritional risk, those on nutritional support had a significantly lower incidence of complications compared with those not on nutritional support [16.7％ (32/192) vs.64.4％ (47/73), P＜0.05] and shorter hospital stay [(7.5±4.6) days vs.(16.3±8.5)days, P ＜ 0.05].Conclusions According to NRS 2002 result, a fairly high percentage of general surgery patients may have nutritional risk.Patients with decreased body mass, less dietary intake, and at higher age may be more likely to have nutritional risk.Nutritional risk may be associated with a higher incidence of postoperative complications and longer hospital stay.Patients at nutritional risk appear to be more likely to benefit from nutritional support.
