Objective To study shorten the time of initial oral intake and fluid intake after general anesthesia in patients receiving oral and maxillofacial surgery,and to reduce the patient′s discomfort and adverse reactions and promote the postoperative recovery. Methods A total of 160 patients were divided into control group and observation group with 80 cases each by random digits table method from April to September in 2014. Patients in control group were allowed to take food orally 6 h after they emerged from anesthesia; while those in observation group were allowed to drink water after 2 h at emergence from anesthesia and take liquid food after 4 h. The mis-aspiration,the fasting glucose,blood pressure,heart rate and the rate of thirst,hunger,nausea,vomiting were observed. Results The rate of thirst, hunger, nausea, vomiting in observation group were significantly lower than those in control group(4 cases vs. 73 cases, 15 cases vs. 76 cases, 10 cases vs. 29 cases, 1 case vs. 7 cases), and there were significant differences, P<0.05, χ2=119.19, 94.83, 12.24, 4.74.The fasting plasma glucose level in observation group was higher than that in control group:(4.82 ±0.74) mmol/L vs. (4.06 ±0.62) mmol/L, and there was significant difference, P<0.05, t=-7.04. The incidence of mis-aspiration was 0 in two groups. The blood pressure and heart rate in control group after operation were lower than those before operation, P<0.05,the t value of systolic pressure, diastolic blood pressure and heart rate:-2.32,-2.03,-4.89 after operation of 1 h,-2.75,-10.54,-6.22 after operation of 3 h,-8.91,-14.76,-6.14 after operation of 5 h. There was no significant difference in blood pressure after operation of 1 h compared with that before operation in observation group, P>0.05, the t value of systolic blood pressure, diastolic blood pressure were-2.73,-2.56. Conclusion Shorten the time of taking food for patients undergoing the oral and maxillofacial surgery,in order to relieve uncomfortable symptoms,prevent hypoglycemia and the hemodynamic disturbance after anesthesia, and promote recovery,early postoperative feeding should be suggested on the premise that they are fully awake.

Objective:To investigate the most effective strategy for mature induction of dendritic cells.Methods:Human monocyte-derived dendritic cells were induced in the presence of cytokines GM-CSF and IL-4. On day 6, the immature DCs were pulsed with each of CD40L, LPS, TNF-? or a cocktail of cytokines(TNF-?, IL-6, IL-1?, PGE2). DCs were harvested after 24 h induction. The surface markers for maturation CD80,CD83,CD86 and HLA-DR were detected by FCM. FITC-Dextra endocytic activity was measured by FCM. IL-12 production was detected by ELISA. The capacity of DCs for T cell activation was detected by MTT assay.Results:CD40L,LPS,TNF-? and the cocktail of cytokines all could induce DCs’ maturation. The most effective scheme for induction of maturation was the cocktail of cytokines, and the expression rate of CD83 was up to 66.91%(P

Objective To investigate the feasibility and safety of autologous tumor tissue lysate loading den-dritic cells(DC) for the treatment of hepatocellular carcinoma (HCC). Methods The monocytes-derived DC were induced and antigen loaded with tumor tissue lysate to produce DC vaccine. Vaccination and clinical observation were conducted in 12 HCC patients for 41 times. Results The average output of DC was 1.69×107(1.69×107±9.44×106>) from 90 ml peripheral blood. 63.41% (26/41)patients appeared to develop delayed-type hypersensitivity after intradermal injection. After an average of 9 months follow up, 1 patient out of 4 recurrence and metastasis pa- tients survived for 17 months. The other three patients progressed. Out of 8 patients undergoing immunotherapy post- operatively,6 patients had no signs of recurrence and the others were found to have liver rceurrence and progression. Conclusion DC based immunotherapy is safe and feasible,with no side effects,which can be applied in the immu- notherapy strategy of HCC patients.

AIM: To investigate the immune stimulation capacity of B7-H1 blockade on immature dendritic cells (DCs) in vitro. METHODS: The human monocyte-derived dendritic cells were induced in the presence of cytokine GM-CSF and IL-4. The expression of B7-H1 was detected by FCM. On blockade of B7-H1, the maturation and endocytic activity, T cells stimulatory proliferation capacity, IL-12 production, T cell differentiation effect of DCs were detected by FCM, MTT assay, ELISA and ELISPOT, respectively. RESULTS: The expression of B7-H1 was increased with the induction of DCs. On day 7, the positive expression was 54.12%, and the TNF-? induced mature DCs had the positive expression rate of 83.64%. The blockade of B7-H1 on immature DCs had sharply increased their T cells stimulatory proliferation capacity and IL-12 production, and efficiently induced the development of Th1/Tc1 cells, but had no effect on their maturation and endocytic activity. CONCLUSION: The blockade of B7-H1 on immature DCs increases its immune stimulation activity. It is valuable to investigate the antitumor immune responses of DCs vaccine with B7-H1 blockade.
