Methods Thirty patients with perennial dizziness and headache were enrolled (including the persons of normal blood lipid). The plaque and blood lipid level were evaluated before and after treatment with Xuezhikang capsule for 3 to 6 months. The carotid arteries were assessed by Doppler ultrasonography. Results 15 patients of abnormal blood lipid adjusted to normal.The carotid intima-media thickness were regressed from (1.15?0.10) mm to(0.99?0.08) mm (P

Objective To evaluate the value of N-terminal prohormone brain natriuretic peptide (NT-proBNP) and tissue Doppler imaging (TDI) in patients with left ventricular diastolic dysfunction.Methods Forty-three patients with diastolic heart failure were enrolled. Pulsed wave (PW) Doppler technology was used to detect early diastolic mitral velocity (E) and TDI was performed to determine the mitral annulus velocity of early diastolic phase (Em). According to the E/Em, patients were divided into three groups: group Ⅰ (E/Em ＜8),group Ⅱ (E/Em 8-15) and group Ⅲ (E/Em ＞ 15). The plasma NT-proBNP was measured. Results The plasma NT-proBNP in group Ⅲ [( 1119 ± 3123) ng/L] was higher than that in group Ⅱ [(684± 1742) ng/L] and group Ⅰ [(276±438) ng/L] (P＜0.01),and the plasma NT-proBNP in group Ⅱ was higher than that in group Ⅰ (P ＜ 0.01 ). The plasma NT-proBNP had positive correlation with E/Em (r = 0.438,P ＜ 0.01 ). Conclusion The plasma NT-proBNP and TDI are useful to evaluate the left ventricular diastolic dysfunction.

Objective To establish the acute hind limb ischemia on Wistar rat with diabetes mellitus.MethodsThirty diabetes rats were induced by intraperitoneal STZ (50 mg/kg) injection, as well as the blood glucose level tested over 16.8 mmol/L. The rats were ligated on the left femoral artery, then the blood perfusion on the hind limbs ischemia was measured by LDPI after the operation. Results The fasting plasma glucose level on 22 Wistar rats(81.5%) was kept above 16.8 mmol/L, and the hind limb blood perfusion would recover slowly to the level of the right side from 1 to 14 day (P

Objective To investigate the effect of Alzheimer' s beta-amyloid (Aβ) on the production and the translocation in cytoplasm of retinoid receptor-α (RXRα). MethodsN2awt cells were treated with Aβ peptide or amyloid protein precursor(APP695) transfection. The nucleus were separated from the cytoplasm by kit. The quantity of RXRα in the nucleus and cytoplasm was detected by Westernblot. The translocation of RXRα in the nucleus and cytoplasm of above N2awt cells or of the cortex cells in the brains of Alzheimer' s disease (AD) patients and their normal control groups was observed by immune fluorescence. ResultsIn N2awt cells, the increasing APP or Aβ had no significant effect on the production of RXRα but resulted in RXRα exporting into cytoplasm, the ratio of RXRα in cytoplasm increased from 3.2％ (in control group) to 17.6％ (in APP+ group) and from 3.8％ (in control group) to 14.3％ (in Aβ + group) respectively; compared with normal cortex cells, the translocation of RXRα in the cytoplasm of the cortex cells in the brains of AD increased significantly. ConclusionAβ may affect RXRα exporting into cytoplasm.

[Objective]To investigate associations between the functional polymorphisms of signal transducer and activator of transcription 4 (STAT4) gene and preeclampsia.[Methods]PCR-restriction fragment length polymorphism was used to genotype rs10181656 and rs16833431 local polymorphism in 228 preeclampsia cases and 179 normal controls.[Results](1)The frequencies of rs10181656C/G were 35.96%,46.37%in genotype C/C,47.81%,44.69%in genotype C/G and 16.23%,8.94%in genotype G/G between preeclampsia patients and normal controls. They reached statistical difference (P = 0.031). There was different distribution in two alleles(C and G)between preeclampsia patients and normal controls(P=0.009).(2)There was no different distribution in 3 genotypes(C/C,C/T,T/T)and 2 alleles(C and T)of rs16833431 C/T between preeclampsia patients and normal controls(P =0.508,0.461).[Conclusions]Functional polymorphisms of the rs10181656 locus could associate with the preeclampsia. The polymor-phisms of the rs16833431 locus could not associate with the preeclampsia.

ObjectiveTo evaluate the primary effect of granulocyte-monocyte colony stimulating factor (GM-CSF) as an immunotherapy option for treatment of residual disease after alloHSCT.Methods Immunotherapy was performed on two patients with blood malignancy to treat residual disease after allo-HSCT. The patient one,who was diagnosed as having MDS-RAEB Ⅱ,showed bone marrow displasis and incomplete chimerism 6 months after unrelated donor HSCT.Immunosuppressive drug was withdrawn without induction of graft-versus-host disease (GVHD).The patient two B-ALL demonstrated a residual disease at molecular level 30 days post-transplantation.Both of them were given GMCSF (300 μg) subcutaneously once every two days for totally three weeks.During the whole period,skin itch and rash,liver function,subgroups of lymphocytes,and MDSCs and DCs in peripheral blood were investigated.Results In case one,grade Ⅰskin acute GVHD (aGVHD) appeared as early as one week after GM-CSF administration,as well as grade Ⅱ (skin and liver) by the end of the third weeks,and GM-CSF injection was withdrawn.One month later since the start of GM-CSF,the patient showed normal bone marrow morphology and full donor type chimerism. Cyclosporine A (CsA), mycophenolate mofetil and methylprednisolone were administered for two weeks to control GVHD.In the other case,grade Ⅰ aGVHD occurred 9 days after GMCSF administration,and whole blood CsA maintained at 0.134-0.472 μmol/L.Prednisone (30mg per day for 5 days) was used to control grade Ⅱ GVHD from the 11th day after GM-CSF,and grade Ⅰ GVHD continued without any intervention.On the 30th day after GM-CSF treatment,bone marrow aspiration showed complete molecular remission.In both of the two cases,no differences in lymphocytic subtypes were revealed before and after GM-CSF administration,while there were trends of increased DC number and decreased MDSCs in peripheral blood.ConclusionThe administration of GM-CSF as an immunotherapy option for blood malignancy may contribute to the clearance of residual disease after Allo-HSCT.

Objective To investigate the value of gastrointestinal tract preparation with oral racean?isodamine tablets and isotonic mannitol in 18 F?FDG PET/CT imaging. Methods From July to September 2013, 129 patients with confirmed or suspected tumors who were referred for 18 F?FDG PET/CT imaging were divided into 2 groups. In the study group (30 males, 37 females, age (53.4±13.9) years), raceanisodam?ine tablets (10 mg) and 1 000-1 200 ml isotonic mannitol solution (2.5%) were orally taken at 10 min after in?jection of 18F?FDG;while in the control group (37 males, 25 females, age (60.0±12.8) years), 1 000-1 200 ml water was given. Mann?Whitney u test was used to compare the difference between the 2 groups in the filling degree of gastrointestinal lumen, delineation of tube wall, physiological uptake, matching degree of PET and CT images, delineation of mesentery, and the influence of gastrointestinal uptake on the identification of ab?dominal and pelvic lesions. χ2 test was used to compare the difference between the 2 groups in the uptake pattern of gastrointestinal tract and the incidence of side effects. Spearman correlation analysis was used to study the correlation between gastrointestinal lumen filling and PET/CT image matching. Results The gas?trointestinal lumen filling, delineation of tube wall, PET/CT image matching in the stomach, small intestine and colon (z: -5.096 to -2.665, all P<0.01),and delineation of mesentery (z=-2.781,P<0.01) were better in the study group than those in the control group. The filling degree of gastrointestinal lumen correla?ted with the corresponding PET/CT image matching (rs:0.521, 0.755, 0.239, all P<0.01). The physio?logical uptake of small intestine and colon was significantly higher in control group than that in the study group( z=-4.131, -3.095, both P<0.01) . But uptake in the stomach between the 2 groups was not signifi?cantly different(z=-0.776, P>0.05). There was statistically significant difference in the uptake pattern of small intestine between the two groups(χ2=12.884, P<0.01) , but not in the stomach and colon (χ2=0.559, 1.083,both P>0.05). The incidence of transient diarrhea (20?9%, 14/67) was higher in the study group than that in the control group (4.8%, 3/62;χ2=7.256,P<0.01). Conclusions The abdominal PET/CT image quality is improved by gastrointestinal preparation with oral raceanisodamine tablets (10 mg) and 1 000-1 200 ml isoton?ic mannitol solution (2.5%).

Objective To observe the effect of elemene injection for the maintenance treatment of malignant pleural effusion.Methods A total of 90 patients with malignant pleural effusion from May 2014 to Apirl 2016 in First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine were collected.They were divided into observation group (n =45) and control group (n =45) according to the random number table method.The patients of the two groups were treated with pleural effusion drainage through thoracocentesis,and Mannatide (Lifein) and carboplatin were poured.The observation group sequentially received maintenance treatment of elemene injection.The therapeutic effects of the two groups were compared.Results At the 12th month after treatment,the difference of relapse rate between the two groups was statistically significant(82.2％ vs.100.0％,x2 =8.780,P =0.003).The median progression-free survival (95％ CI) of the observation group and the control group were 10.00 (9.15-10.85) months and 6.00(4.74-7.26) months respectively,with a significant difference (x2 =40.475,P ＜ 0.001).The improvement rates of life quality of the observation group were 82.22％,57.78％,54.55％ respectively at one,six,twelve months after perfusion treatment,and the improvement rates of the control group were 84.44％,23.26％,0 respectively.The data differences between the two groups were statistically significant at six,twelve months (x2 =10.840,P =0.001;x2 =32.390,P ＜ 0.001).The one year survival rates of the observation group and the control group were 97.78％ and 95.56％,and the difference was statistically significant (P =1.000).Conclusion The effect of elemene injection for the maintenance treatment of malignant pleural effusion is obvious,which can prolong the progression-free survival time and can significantly improve the quality of life.

Objective To identify the pathogenesis gene mutation of a pedigree with Cockayne syndrome.Methods The peripheral blood samples of the patient and his family members were collected and the genomic DNA was then extracted.Whole exome sequencing(WES)was performed for proband′s DNA.The disease-causing mutations were identified by bioinformatics analysis and pedigree analysis. Meanwhile,the mutations were confirmed by Sanger sequencing.Results Two novel mutations in ERCC8 gene,including c.400-2A >G and c.394_398delATGTA(p.L132fs)were identified in proband.The splicing mutation originated from his father and changed the splice acceptor site AG to GG, thus possibly caused alternative splicing.The c.394_398delATGTA(p.L132fs)frameshifting mutation was inherited from his mother.The proband′s sister also carried the same compound heterozygous mutation and had the same phenotype as proband.Conclusion The pathogenesis ERCC8 gene mutation of this pedigree with Cockayne syndrome was identified by using whole exome sequencing.
