To investigate the safety, efficacy and feasibility of the administration of a number of DCs from HLA identical donor in the treatment of leukemia. Peripheral blood mononuclear cells (PBMNCs) of HLA identical healthy donors were collected. PBMNCs were cultivated initially with IL 4,hGM CSF,TNF ?, and stimulated by lysate of leukemic cells.Dendritic cells were induced and given to the patients. The response of the patients to the infusion of DCs was observed. Clinical observation showed that the progress of leukemia was limited partly. There was no toxicity directly referable to this treatment. It is feasible and safe to generate and administer DCs pulsed with tumor lysate, suggesting that it could be a potential treatment for advanced acute myeloid leukemia.

ObjectiveTo evaluate surgical management of femoral pseudoaneurysm caused by injection of addictive drugs.MethedsData of 18 cases were reviewed and analysed retrospectively.13 patients underwent primary expanded polytetrafluoroethylene(ePTFE) external iliofemoral bypass (end to side) grafting. Postoperative anastomotic burst and bleeding in one of the 3 patients undergoing saphenous vein autotransplant in situ was successfully treated by ePTFE grafting. Results All of the grafts were patent as demonstrated by postoperative color Dopler ultrasonography. Although 2 patients had their femoral arteries ligated, limbs of all the 18 patients were salvaged.ConclusionsWhen a suitable saphenous vein is not available for autotransplantation, an artificial vessel grafting is still an effective procedure for managing femoral artery false aneurysm.During operation thorough debridement and avoidance of artificial vessel contamination are the most important factors for preventing infective complications of the graft.

0.05),and the antifebric time of group A was shorter than that of group B.No significant difference was found in the incidence rate of side reaction between two groups. CONCLUSIONS Ceftazidime and vancomycin combination is more effective than ceftazidime alone.

Objective To analyze long-term efficacy after surgical treatment of primary liver cancer with fluorouracil plus oxaliplatin plus gemcitabine joint implementation to prevent the overall intervention effect of hepatic arterial infusion chemotherapy and radical resection of hepatocellular carcinoma following ascension.Methods60 cases of primary hepatocellular carcinoma were randomly divided into study group and control group according to the random number method in our hospital from February 2011 to November2013, 30 cases in each group.All patients underwent radical resection of liver cancer and liver (partial) resection.In the control group, the patients were treated with anti viral or immune enhancement after surgery, and the follow-up treatment was not carried out.In study group were given anti-virus or immune intensive treatment and at the end of surgery 3 and 7 weeks after the implementation of a prophylactic transcatheter arterial infusion chemotherapy and selecting drug 5-FU, oxaliplatin and gemcitabine.During 3 years of follow-up, the incidence of adverse reactions in the 3 groups was statistically analyzed, and the recurrence free survival rate, disease-free survival rate and overall survival rate of the two groups were statistically analyzed.ResultsAll patients completed the follow-up, there was no loss of follow-up cases.In adverse reactions, the study group patients were successfully tolerated hepatic artery infusion chemotherapy, no obvious adverse reactions or drug toxicity, more no interruption of chemotherapy cases.The recurrence free survival rate, disease-free survival rate and overall survival rate of the study group were 83.33%, 70.00%, 86.67%, respectively, which were significantly higher than those in the control group (60.00%, 43.33%, 63.33%) (P<0.05).ConclusionPrimary hepatocellular carcinoma should be treated with prophylactic hepatic arterial infusion chemotherapy in time after radical operation, which can greatly improve the survival rate of patients and ensure long-term curative effect.

Objective To explore the clinical effect and safety of high frequency oscillatory ventilation (HFOV) combined thoracic close drainage for the treatment of mechanical ventilated neonates with pneumothorax.Methods Twenty-two neonates were enrolled in this study,who needed mechanical ventilation diagnosed with neonatal pneumothorax and received treatment of HFOV combined thoracic close drainage from Jan.2012 and Jun.2014 in the People's Hospital of Dongguan.We recorded blood gas analysis and parameters of breathing machine before using HFOV and 2,12,24,48 hours after using HFOV respectively.Results There were significant differences between HFOV before use (0) and 2,12,24,48 hours after using HFOV in terms of blood pH value,arterial partial pressure of oxygen(PaO2),partial pressure of arterial carbon dioxide (PaCO2),oxygenation index (OI),the inspired oxygen concentration (FiO2),mean airway pressure (MAP) (F =6.606,17.760,8.387,17.242,25.185; P ＜ 0.05).Compared with before using HFOV combined thoracic close drainage,PaO2 was significantly increased from (51.25 ± 13.16) mmHg to (62.60 ± 15.95) mmHg.PaCO2 was significantly dropped from (63.57 ± 13.81) mmHg to (54.02 ± 11.58) mmHg and OI was dropped sharply from (16.57 ± 9.09) to (11.28 ± 4.67) at 2 hours after using HFOV combined thoracic close drainage (P ＜ 0.05).FiO2 significantly decreased from (0.76 ± 0.15) to (0.60 ± 0.13),as well as MAP from (9.91 ± 1.44) cm H2 Oto (8.50 ± 1.68) cm H2O.Furthermore,pH was significantly improved from (7.24 ± 0.15) to (7.34 ±0.10) at 12 hours later(P ＜0.05).PH,PaO2,PaCO2 were roughly back to normal at 48 hours after treatment.The main complications were intraventricular hemorrhage (2 cases),subarachnoid hemorrhage (2 cases),ventilator associated pneumonia (1 case) and pulmonary hemorrhage (1 case) (not during the time of HFOV treatment).Conclusion HFOV combined thoracic close drainage for the treatment of neonates with pneumothorax is safety and effective methods.

ObjectiveTo explore the effect of Vitalstim neuromuscular electrical stimulation on neurogenic swallowing dysfunction. Methods82 patients were divided into three groups: group A received swallowing behavior therapy, group B received Vitalstim neuromuscular electrical stimulation, group C received Vitalstim neuromuscular electrical stimulation and swallowing behavior therapy, 10 times as one course. ResultsTotal efficiency was 72.7% for group A, 82.6% for group B, and 94.5% for group C, after 1～2 courses. Scores of videofluorocopic swallowing study (VFSS) was significantly higher in group C than in the other groups (P=0.000). ConclusionVitalstim neuromuscular electrical stimulation on the basis of swallowing behavior therapy can improve swallowing function of neurogenic dysphagia, especially in pseudobulbar palsy.

Objective To partially purify the toxic factor secreted by A. corymbifera and to analyze the mechanism of A. corymbifera-induced human umbilical vein endothelial cell (HUVEC) apoptosis. Methods Glycoprotein secreted by A. corymbifera was purified by Con A Lectin chromatography. The influence of different protein fractions on HUVEC apoptosis was determined by flow eytometer. Both denaturing and nondenaturing deglycosylation of purified glycoprotein was performed and the ability of the protein moiety and carbohydrate moiety to induce HUVEC apoptosis was evaluated respectively. Activation of related caspases during A. corymbifera-induced apoptosis was analyzed by Western blot. The role of caspase-8 and -9 in HUVEC apoptosis was investigated using caspase inhibitors. Caspase inhibitors were used to stop the suppression of HUVEC viability by XTT assay. Results Flow cytometric analysis shows the total protein as well as the glycoprotein fraction of A. corymbifera may induce HUVEC apoptosis in a dose dependent manner. In contrast, similar activity was not observed in the non-glycoprotein fraction. Neither deglycosylated protein nor carbohydrate moiety is able to induce HUVEC apoptosis alone. In the apoptotic signaling pathway, caspase9, caspase-3 and cytochrome C were activated significantly, except caspase-8. Moreover, caspase-9 inhibitor, instead of caspase-8 inhibitor, completely abrogates A. corymbifera-induced HUVEC apoptosis. Caspase9 and caspase-3 inhibitors completely waived the suppression of HUVEC viability by A. corymbifera. Conclusion Glycoprotein secreted by A. corymbifera is associated with HUVEC apoptosis. Intact glycoprotein is essential for the apoptotic progress. Intrinsic apoptotic signaling pathway mediates A. corymbifera-induced HUVEC apoptosis.

Objective To analyze the influence of Absidia corymbifera on cell activity of human umbilical vein endothelial cells (HUVEC) as well as the related mechanism. Methods Time course analy sis of the influence of A. corymbifera on cell viability of HUVEC was determined by cell counting after Trypan blue staining. Apoptosis of HUVEC induced by A. corymbifera was observed under fluorescence microscope after treatment with apoptosis detection kit. Time course analysis of HUVEC apoptosis induced by A. corymbifera was detected by flow cytometry quantitatively. Effect of caspase-3 inhibitor on A. corymbifera associated apoptosis was also evaluated at the same time. Activation of caspase-3 inside HUVEC was detected by Western blot. Results A. corymbifera inhibited cell viability of HUVEC in a time-dependent manner by Trypan blue staining. After 12 hours' co-culture, A. corymbifera began to show suppression on cell viability (P =0. 001 ). Fluorescence microscope observation revealed A. corymbifera induced apoptosis of HUVEC instead of necrosis. Flow cytometry analysis showed A. corymbifera induced apoptosis of HUVEC in a time-dependent manner. A. corymbifera began to show obvious effect on apoptosis after 12 h co-culture (P =0.0036). Moreover, A. corymbifera-associated apoptosis was almost abrogated completely by caspase-3 inhibitor. Western blot analysis demonstrated that A. corymbifera triggered the activation of caspase-3 inside HUVEC in a timedependent fashion. Conclusion A. corymbifera induces apoptosis of HUVEC in vitro. Such apoptotic signal is transmitted through caspase cascade reaction.

Objective Serum miRNA has been regarded as a potential biomarker for diagnosis, therapeutic evaluation and prognostic prediction in cancer patients. This study aims to explore the clinical significance of the expression level of metastasis- related microRNA (miR- 18b) in the serum in AFP- negative (≤ 20 ng/ml) hepatocellular carcinoma(HCC) patients receiving radiofrequency ablation (RFA). Methods A total of 131 HCC patients with negative serum AFP, who were encountered during the period from January 2007 to January 2011 at authors’ hospital, were enrolled in this study. Radiofrequency ablation (RFA) of the lesions was carried out in all patients. Serum samples were collected before RFA. Forty - three healthy individuals were selected for control. The expression level of serum miR - 18b was deternmined by using quantitative real- time PCR method in all the patients and the healthy individuals. The correlations of the expression level of serum miR - 18b with clinico - pathological factors, postoperative recurrence, overall cirrhosis (P = 0.035), tumor diameter (P < 0.01) and tumor differentiation (P = 0.020). During the follow-up period, 79 patients (60.3%) developed recurrent tumors, and the expression level of serum miR- 18b in them was dramatically higher than that in the patients showing no recurrence (3.26 ± 1.28 vs. 2.42 ± 0.86, P <0.01). The incidence of recurrence after RFA, especially distant intrahepatic metastasis, in patients with higher expression level of serum miR- 18b was strikingly higher than that in patients with lower expression level of serum miR- 18b (72.3% vs. 48.5%, P = 0.005). Kaplan- Meier survival analysis indicated that both overall survival rate and recurrence- free survival rate of patients with higher expression level of serum miR-18b were significantly lower than those of patients with lower expression level of serum miR- 18b. Conclusion The expression level of serum miR - 18b is significantly elevated in AFP - negative HCC patients. The expression level of serum miR- 18b might be used as an ideal biomarker for monitoring tumor recurrence as well as for predicting prognosis after RFA.

OBJECTIVE: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. METHODS: A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). RESULTS: Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. CONCLUSION: The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.
