Objective To investigate the clinical significance of serum lipids level changes in patients with acute leukemia.Method Serum total cholesterol(TC),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),triglyceride(TG),apolipoprotein A1(apoA1),apolipoprotein B(apoB)were determined by using enzymatic methods before treatment and in complete remission period.Results The level of TC,LDL-C,HDL-C,apoA1,apoB before treatment were significantly lower than that in control group and in period of complete remission (P

Objective To investigate the therapeutic effect and safety of micro-dosage heparin therapy for acute leukemia with pre-diffuse intravascular coagulation (pre-DIC).Methods 36 cases of acute leukemia with pre-DIC were divided into two groups,18 cases were treated with micro-dosage heparin therapy (group A),18 cases were treated with conventional therapy(group B).Results Within the first 10 days,the cases which transformed to diffuse intravascular coagulation (DIC) in group A were significantly lower than group B(P

The effect of rhGM-CSF/IL-3 on apoptosis of Ara-C-induced myeloid leukemic cell line HL- 60 was investigated. The results indicated that treatment with rhGM-CSF/IL-3 in combination with Ara-C significantly inhibited the colony growth of HL-60 and enhanced the oligonucleosomal DNA fragmentation as compared with Ara-C alone. The Ara-C mediated apoptosis rates of HL-60 cells treated with rhGM-CSF/IL-3 fusion protein alone were markablely improved compared with treatment with rhIL-3 plus rhGM-CSF, it was noted that the Ara-C mediated of apoptosis normal peripheral white blood cells was less affected by rhGM-CSF/IL-3. It suggested that rhGM-CSF/IL-3 could be used as a possible curing drug during the phase of induced remission of leukemia.

Objective To study the effects of rehabilitation training combined with the transplantation of bone marrow mesenchymal stem cells-derived neural stem cells (BMSC-D-NSCs) on the expression of Nogo-A and NgR protein in rats after spinal cord injury (SCI).Methods The spinal cords of eighty Sprague-Dawley rats were injured using a modified Allen′s impactor (H = 25 mm) at T10. The injured rats were randomly divided into a combination therapy group which was given rehabilitation training and cell transplants, a cell graft group, a rehabilitation training group and a control group. At the 7th day post SCI, BMSC-D-NSCs were transplanted into the injured spinal cords of the rats in the combination therapy and cell graft groups. Hindlimb movement was assessed using the BassoBeattie-Bresnahan (BBB) scale every week, and protein was extracted from the injured spinal cord tissue for Nogo-A and NgR determination by Western blotting at the 1st, 3rd and 7th day after cell transplantation.Results The average BBB score of the rats in the combination therapy group was significantly higher than that of the other groups from 2 weeks post transplantation. The scores in the rehabilitation training group were significantly higher than in the control group from the 5th week post transplantation. Western blotting showed high expression of Nogo-A and NgR protein 24 h post surgery, but these declined with time. For Nogo-A there was a significant difference among the groups at all three time points. In the combination therapy group the expression declined to a minimum by the 7th day. For NgR protein there was no significant difference between the 1st and 3rd day in any group.Conclusions Rehabilitation training combined with BMSC-D-NSC transplantation can have a synergistic effect on functional recovery from SCI. It can down regulate the expression of Nogo-A and NgR protein.

Objective To explore preliminarily the effects of preoperative depression condition in patients with breast cancer on the efficacy of intravenous analgesia with dezocine and the serum level of 5 hydroxytryptamine.Methods Sixty patients with breast cancer were assessed with Hamilton depression scale (HAMD).The total patients were divided into three groups according to HAMD scores,including normal group (26 cases),suspicious group (22 cases),and depression group (12 cases).The postoperative analgesia was facilitated with patients intravenous control analgesia with dezocine and the postoperative pain was assessed by visual analogue scale (VAS) at 2 hours,12 hours,and 24 hours.Yhe serum concentration of 5 hydroxytryptamine was measured by enzyme-linked immunosorbent assays before anesthesia,2 hours after surgery beginning,and 24 hours after surgery.Results The postoperative VAS at 12 hours and 24 hours in suspicious group and in depression group were higher than those in normal group (P ＜ 0.05).There was no statistical difference between depression and suspicious groups (P ＞ 0.05).The serum concentrations of 5 hydroxytryptamine in three groups increased obviously at 2 hours after surgery beginning (P＜0.05),and then decreased at 24 hours postoperation.The serum concentrations of 5 hydroxytryptamine in suspicious group and depression group at three measurement point were significantly lower than those in normal group (P ＜0.05).The serum concentrations of 5 hydroxytryptamine in depression group at three measurement point were significantly lower than those in suspicious group (P ＜ 0.05).Conclusions Under this preliminary study condition,the preoperative severity of the depression in patients with breast cancer may affect the analgesia effect of patients intravenous control analgesia with dezocine and maybe have some relationships with serum levels of 5 hydroxytryptamine.

OBJECTIVETo summarize the techniques and evaluate the therapeutic effect of posterior fixation and fusion in the treatment of Os odontoideum complicated by atlantoaxial dislocation.

METHODSFrom March, 2007 to October, 2010, 10 patients with Os odontoideum (including 6 male and 4 female patients aged from 20 to 65 years, mean 39.8 years) were treated in our hospital. Before and after the operation, the patients underwent X ray, CT and MRI examinations to measure and evaluate the degree of dislocation and neural compression. After preoperative traction for 1-2 weeks, all the 10 patients showed deductible atlantoaxial dislocation. Through a posterior approach, Atlantoaxial pedicle screws fixation were performed in 9 cases, and C2/3 pedicle-Occiput screw fixation was performed in 1 case. All the patients wore cervical collars as external support for 3 months after the operation.

RESULTSThe mean operative time was 3 h in these patients with a mean intraoperative blood loss of 420 ml. The symptoms were relieved after the surgery in all the patients, who showed no neck pain or neurological defects. The patients were followed up for 6 to 52 months (mean 22 months), and bony fusion was observed in all the 10 cases within 6 to 8 months without such complications as internal fixation failure or redislocation of the atlas.

CONCLUSIONPatients with Os odontoideum complicated by atlantoaxial dislocation should undergo surgical stabilization to avoid severe neurological injury. Pedicle screw instrument in the atlas allows restoration of the spinal stability, short-segment fusion, and maximal preservation of the mobility of the neck.

Objective To explore the diagnostic value of serum lipoprotein(a)[Lp(a)]in cerebral infarction by a model of Logistic regression and receiver operating characteristic(ROC)curve.Methods A total of 316 patients with cerebral thrombosis from Foshan Hospital Affiliated to Southern Medical University were col-lected.According to the diagnostic criteria,the patients were divided into cerebral thrombosis group(196 ca-ses)and non-cerebral thrombosis group(120 cases).All the subjects were tested for Lp(a)by immune turbi-dimetry.To evaluate the diagnostic value of Lp(a)by applying logistic regression model,drawing ROC curves and calculating the area under the curve(AUC).Results The P25,P50,P75of Lp(a)in cerebral thrombosis group and non-cerebral thrombosis group were 97.23,238.22,430.01 and 29.80,92.27,233.86,the average rank were 185.42 and 114.52,the differences in the two groups were significant(P<0.05).Logistic regres-sion showed that the correlation between Lp(a)level and cerebral thrombosis was positive,the partial regres-sion coefficient(B)was 0.005,Wald value was 31.295.It suggested that when the levels of Lp(a)was higher the risk of cerebral thrombosis increased.The most valuable diagnosis level was 305.80 mg/L.And the area under the ROC curve(AUC)was 0.724,which has moderate diagnostic efficacy.Diagnostic specificity was 91.7%,misdiagnosis rate was 8.3%,negative predictive value was 48.7%,sensitivity was 40.8%,omission rate was 59.2%,positive predictive value was 88.9%.Conclusion The level of serum Lp(a)has high diag-nostic specificity for the diagnosis of cerebral thrombosis.

OBJECTIVETo investigate the gene expression of two kinds of constitutive nitric oxide synthase (cNOS): neuronal NOS (nNOS) and endothelial NOS (eNOS) in injured spinal cord tissue.

METHODSThirty-six adult Sprague-Dawley rats were divided randomly into six groups: the normal group and the injury groups (2, 6, 12, 24, 48 h after injury, respectively). A compression injury model of the spinal cord wa s ma de and gene expression of nNOS and eNOS were examined by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSThe gene expression of nNOS and eNOS was detected in the normal group and they were up-regulated quickly after injury, reaching the maximum at 6 h. There was no difference between gene expression of nNOS and eNO S in the normal group, but in each injury group the gene expression of eNOS was much higher than that of nNOS.

CONCLUSIONSExpression of constitutive NOS (cNOS) in spinal co rd tissue was up-regulated after injury mainly in the early stage. cNOS as a wh ole offers protection in spinal cord injury, but different cNOS may play different roles.
