OBJECTIVE: To evaluate the curative efficacy of recombinate erythropoietin(r-HuEPO) administered through different route for patients receiving hemodialysis.METHODS: 40 patients undergoing maintenance hemodialysis(MHD) were randomized into subcutaneous injection group and intravenous injection group.The hemoglobin(Hb),hematokrit(Hct) and the adverse effect within 12 weeks were observed.RESULTS: The Hb/Hct level of the two groups increased with the prolonging of treatment,which increased significantly at 8 weeks and 12 weeks as compared with before treatment(P

Although there are many drugs for the treatment'of cerebral infarction, no satisfactory efficacy has achieved. Mesenehymal stromal cells (MSCs) have multilineage differentiation potential and self-renewing capability, and can differentiate into neurons. The transplanted MSCs can improve neurological deficit after cerebral infarction, promote the recovery of neurological function, and thereby reduce the disability of cerebral infarction through the mechanisms such as releasing nutritional factors and growth nutritional factors, promoting angiogenesis. The use of MSCs for cell transplantation is likely to be an ideal means in the treatment of cerebral infarction.

20% lymphocytes)was documented in all patients who underwent bronchoalveolar lavage(BAL).In addition,inversion of the CD4/CD8 ratio(mean value:0.64?0.21)was observed in the patients.Non-specific IgM and IgG antibodies to antigens were documented in 13/14(92.9%)of BAL patients.Ten patients were cured by glucocorticoid,others by anti-infective therapy.We rechecked the HRCT which displayed the shade of lung in 12 patients(85.7%)vanishing completely,2 patients'(14.3%)partly.Conclusion There is no specificity in the clinical manifestations,change of mageology,pulmonary function and the immunologic test.However,compared with other methods,we find the test of BAL is more valuable to the diagnosis.It is critical to avoid the antigen,and we find the curative effect of the glucocorticoid is significant.

Objective To investigate the effect of neoadjuvant chemotherapy on EC50 of propofol given by TCI which produces loss of consciousness (LOC) in breast cancer patients.Methods Ninety ASA Ⅰ or Ⅱ breast cancer patients aged 30-60 yr scheduled for elective surgery were allocated into 3 groups according to the chemotherapy the patients received (n=30 each):group Ⅰ control (group C) received no chemotherapy;group Ⅱ taxol and group Ⅲ adriamycine+cyclophosphamide+5-Fu.The patients were unpremedicated.The EC50 of propofol given by TCI was determined by up-and-down technique.The initial effect-site concentration (Ce) of propofol was 2.07μg/ml and the ratio between the 2 successive Ce was 1.09.Loss of response to verbal command and eyelash stimulation was used as sighs of LOC.The EC50 of propofol was calculated.Results The EC50 of propofol causing LOC was significantly lower in group Ⅱ and Ⅲ than in control group.There was no significant difference in the EC50 of propofol which produces LOC between group Ⅱ and Ⅲ.Conclusion The EC50 of propofol causing LOC in breast cancerpatients is decreased by adjuvant chemotherapy.

Objective To evaluate the expression of Tc17 in a cigarette smoke-induced mice model of emphysema.To explore the probable mechanisms about how Tc17 cells to elevate in lungs of mice.Methods Forty male Balb/c mice were randomly divided into four groups,including control group ( 12 weeks,C12),control group (24 weeks,C24),smoke-exposure group (12 weeks,S12) and smoke-exposure group (24 weeks,S24 ),10 mice each group,Emphysema of mice was observed by HE pigmentation.Morphological changes were evaluated by mean linear intercepts (Lm) and destructive index (DI).The proportion of CD8+ IL-17 + Tc17,CD8+ IL-17 + CC chemokine receptor type 6 ( CCR6 ) + and 6CCR6 + Tc17 cells in lungs of mice was determined by flow cytometry.The mRNA expressions of retinoidrelated orphan nuclear receptor(RORγt) and IL-17 were evaluated by real-time PCR.The levels of IL-1 β,IL-6,IL-23,transforming growth factor β (TGFβ) and CC chemokine ligand 20 (CCL20) were tested by ELISA.Correlations among these indexes were analyzed.Results Lm and DI were significantly higher in S12 and S24 than in C12 and C24,S24 in particular (t value 4.378-15.188,all P ＜ 0.05).The percentages of Tc17 in S12 and S24[(9.28 ± 1.12)%,( 13.13 ±3.56)%]was significantly increased as compared with that in C12 and C24[(2.40 ±0.60 )%,(2.64 ±0.96 )%],S24 in particular.The mRNA levels of RORγt and IL-17 in S12 and S24 were higher than in C12 and C24,S12 and S24 in particular.There was significant difference (all P ＜0.05 ).The frequency of Tc17 cells had a positive correlation with Lm and DI ( r value were 0.734 and 0.884 respectively,P ＜ 0.01 ).The percentages of CD8+ IL-17 + CCR6 +T cells and CCR6 + Tc17 were significantly elevated in S12 and S24 compared to C12 and C24,S24 in particular (all P ＜ 0.05 ).There was positive correlation between Tc17 cell ratio and CCL20 levels( r =0.899,P ＜0.01 ).The levels of IL-1 β,IL-6,IL-23 and TGFβ in S12 and S24 were significantly increased as compared with that in C12 and C24.There was significant difference (all P ＜0.05).Meanwhile,the frequency of Tc17 cells had a positive correlation with IL-1β,IL-6,IL-23,and TGFβ.Conclusions An up-regulation of proportions Tc17 in lungs of cigarette smoke-induced emphysema mice were detected.The CCR6/CCL20 axis and the increased IL-1β,IL-6,IL-23 and TGFβ probably contributed to this up-regulation.

The adenosine triphosphate (ATP)-binding cassette transporter G1 (ABCG1),a member of the superfamily of ATP-binding cassette transporters,is involved in the efflux of cholesterol and phospholipids from cells,and it maintains the intracellular hpid homeostasis.ABCG1 deficiency results in foam cell formation,endothelial dysfunction,and inflammatory reaction,and it further leads to the development and progression of atherosclerosis.However,the role of ABCG1 in atherosclerosis in animal experiments and human studies is still a debatable matter.In this paper,the recent findings on the role of ABCG1 in atherosclerotic disease are reviewed.

Objective To determine main factors associated with quality of life in epileptics in northen China especially seizure severity and stigma, and the variations between men and women. Methods All patients with epilepsy aged 18-65 years were selected from the First Affiliated Hospital of China Medical University, tested from March 2014 to March 2015. All of them completed the general social science data, the Quality of Life Inventory in Epilepsy-31 (QOLIE-31), Liverpool Adverse Events Profile (LEAP), the National Hospital Seizure Severity Scale (NHS3), Epilepsy Stigma Scale (ESS), Self-rating Anxiety Scale ( SAS) and Hamilton Depression Scale ( HAMD) assessment. Results A total of 123 patients with epilepsy (60 men, 63 women) were interviewed. QOLIE-31 scores were 55. 81 ± 10. 17 in female patients, 65. 35 ± 10. 89 in male patients, the difference being statistically significant (t=2. 90, P<0. 05). ESS (1(0,2)), SAS(31. 85 ± 8. 16), HAMD (4. 38 ± 2. 90) scores of female patients were higher than that of male patients (0(0,0), 26. 93 ± 3. 45, 2. 80 ± 1. 39;U= -2. 710, t=2. 48, 2. 20, all P<0. 05). Multiple factors analysis and multiple stepwise regression analysis on quality of life revealed that depression (β= -0. 516, P<0. 01) and the severity of epilepsy (β= -0. 338, P=0. 01) were two strong predictors of QOLIE-31 overall scores. The linear regression showed that there was a direct link between shame and degree of depression (β = 0. 515, P= 0. 001 ) . Conclusions The main factors affecting the quality of life in epileptics in northen China are depression and seizure severity. Compared with male patients, female patients have a lower quality of life, and poorer psychological status, such as shame, depression and anxiety. There is a direct link between shame and depression in epileptics.

Objective To study the relevant factors of malignant change of colorectal adenoma.

Objective To explore the significance of multiple microelectrode guided technique in determining the sensory?motor area of the sub?thalamic nucleus(STN)in deep brain stimulation(DBS)surgeries. Methods A total of 22 electrophysiological recording data of STNs recorded by multiple microelectrode was retrospectively analyzed ,while another 20 electrophysiological recording data of STNs recorded by a single micro?electrode was recruited as the control group. Results A total of 64 microelectrodes were used in 22 STNs guided by multiple electrophysiological recording electrodes. Sensory or motor activated potentials were recorded in 21 sides(95.5%),while regular discharge was recorded in one side. The average length of typical STN activity on the optimal channel of multiple electrophysiological recording electrodes was 5.58±0.53 mm,and the average length of sensory or motor activated potentials was 3.27±1.54 mm. In contrast,the average length of typical STN activity recorded by single microelectrode was 5.02±1.01 mm. However,sensory or motor activated potentials were recorded in 13 sides(65.0%)with the average length of 1.36±0.98 mm. Among the 22 STNs guided by multiple electrophysiological recording electrodes,the final implanted target was consistent with the initially selected anatomic target in 13 sides(coincidence rate,59.1%). In 9 sides,the electrophysiological target was inconsistent with the initially selected anatomic target. Conclusion STN DBS performed with multiple electrophysiological recording electrodes resulted in better outcomes of recording of the average length of typical STN activity or the average length of sensory or motor activated potentials of STN ,final confirmation of STN sensory motor area and determination of the optimal channel of implantation. Application of multiple electrophysiological recording electrodes provides a premise for the precise electrode placement in STN DBS surgeries.

Objective To investigate the influence of neoadjuvant chemotherapy on the occurrence of postoperative nausea and vomiting ( PONV) after radical mastectomy. Methods A total of 286 breast cancer patients, aged 18-60 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective modified radical mastectomy under general anesthesia in our hospital, were divided into either non?chemotherapy group ( n=106 ) or neoadjuvent chemotherapy group ( n=180 ) . General anesthesia was induced with iv propofol 2 mg∕kg, rocuronium 0. 6 mg∕kg and sufentanil 0. 2 μg∕kg. The patients were endotracheally intubated. The concentration of sevoflurane inhaled was adjusted according to the value of bispectral index, and bispectral index value was maintain at 40-50. Ondansetron 8 mg and flurbiprofen axetil 100 mg were injected intravenously at 30 min before the end of surgery. If vomiting occurred for 2 consecutive times, and continuous nausea and vomiting appeared from the time point after extubation to 24 h after surgery, and the patients required treatment, rescue medication was used. The occurrence and severity of PONVwithin 24 h after surgery and requirement for rescue medication were recorded. Results Compared with non?chemotherapy group, the incidence of PONV within 24 h after surgery and requirement for rescue medication were significantly increased, and the severity of PONV was aggravated in neoadjuvent chemotherapy group (P<0.05). Conclusion Neoadjuvant chemotherapy before surgery can increase the risk and severity of PONV after modified radical mastectomy.
