The construction of charity culture has always been a weak element in medical institutions,thus it is in great need to promote the construction of ideological and charity culture.Medical staff should cultivate themselves with charity philosophy to promote their sincerity,comfort,and self-cultivation for medical career,and combine charity philosophy and medical ethics so as to add charity to their clinical thinking,ideology and behaviors.Therefore,medical staff's morality of medical service can be enhanced gradually.

Objective:To evaluate dendritic cells induced immune response against hepatocellular carcinoma by pulsed CD34+ hematopoietic stem cells originated dendritic cells with p53 gene.Methods:CD34+ hematopoietic stem cells were harvested after mobilization by chemotherapy and G-CSF.CD34+ hematopoietic stem cell apheresis was induced to differentiate into dendritic cells by cytokine cocktail IL-4,GM-CSF and TNF-?.On day 7,dendritic cells were transfected with plasmid pEGFP-C3/p53 DNA.The CTL response triggered by p53 pulsed dendritic cells was assayed by MTT method.Results:Dendritic cells originated from CD34+ cell apheresis had typical dendritic stick and expressed high level CD1a,CD11c,CD80,CD86,and HLA-DR molecules.After being pulsed with p53 gene,dendritic cells expressed green fluorescence protein and immunofluorescence assay(Cy3 labeled anti-P53 antibody)showed that transfected dendritic cells emitted red fluorescence.Dendritic cells inducing CTL response against HMCC97 cells(P53 positive)and HepG2 cells(P53 negative)were assessed by MTT method.P53 pulsed dendritic cells could induce P53 specific immune response against HMCC97 cells and the cytotoxin rate was(49.3?4.6)% compared with pEGFP-C3 transfection group [(25.4?4.1)%] and control group[(24.8?3.8)%](P0.05).Conclusion:P53 gene transfecting hematopoietic stem cell apheresis originated dendritic cells could induce specific CTL response against P53-expressing hepatocellular carcinoma cells.P53 may be a potential candidate for dendritic cell based immunotherapy of cancer.

Objective: To study the relationship between the patient satisfaction with complete denture and the pain perception threshold (PPT) of alveolar ridge mucosa. Methods: Forty-five edentulous patients with complete denture were investigated with the questionnaire of patient satisfaction, PPT of alveolar ridge mucosa in the patients was measured with a pressure algometer. Results: No difference was found in the PPT of alveolar ridge mucosa between the left and the right side. The PPT was found to be higher in maxillary site than in mandibular side(P

Objective The loss of NF2 gene in cutaneous schwannomas of neurofibromatosis type 2 patients was investigated in order to explore the tumorigenesis and characteristics of NF2 tumor suppressor gene, and to provide evidence for presymptomatic gene diagnosis for NF2 patients. Methods DNA was extracted from whole blood and frozen tumor tissue, respectively. Genotyping was performed using 6 microsatellite markers flanking or within the NF2 gene: CRYB2－ D22S193－ NF2CA1－ NF2CA3－ D22S268－ D22S430, which is tightly linked to the NF2 gene and analyzed on an ABI Genetic Analyzer 310 after PCR amplification. Results A total of 18,14,0,13,16,12 samples showed loss of heterozygosity at microsatellite markers CRYB2， D22S193， NF2CA1， NF2CA3， D22S268， D22S430 in 43 samples of cutaneous schwannomas, respectively. Conclusions The method for detection of NF2 allelic loss was established. Frequent allelic loss reconfirms that NF2 gene is a tumor suppressor gene. The observation that tumors with or without allelic loss of the NF2 gene exist in the same patient indicates that these tumors are originated from different clones in which genetic alterations occurred independently.

Objective To investigate nutritional support in the treatment of cancer in recent years.Methods Seperately diSCUSS on application conditions of enteral nutrition and parenteral nutrition in the treatment of cancer and its advantages and disadvantages.Results Enteral nutrition can improve digestive funcdon,reduce costs and enhance immunity.Parenmral nutrition can supplement insufficiency of enteral niltrition and inhibit tumor growth by selecting the kinds of nuWients to support a normal body function.Conclusion Enteral nutrition combined witll parenteral nutrition iS a suitable means of nutritional support in the treatment ofcancer.

Objective To assess the efficacy and safety of argon plasma coagulation(APC) in treating patients with Barrett's esophagus.Methods Two reviewers independently searched the Cochrane Library(Issue 2,2008),MEDLINE(January 1948 to November 2008),and CNKI(January 1999 to November 2008),respectively.The quality of the included studies was assessed according to the guidance in the Cochrane Handbook of systematic reviews of interventions.Results Six randomized controlled trials involving 253 patients with Barrett's esophagus met the inclusion criteria and were included.One trial reported that the ablation rate of patients in the APC group was significantly higher than that in the endoscopic surveillance group.Followed up one year,the ablation rate in APC group was 63% compared with 15% in the control group(P

Objective To analyse the survival time and related factors of patients with brain stem glioma who received 3DCRT.Methods Thirty-six patients with brain stem tumor were admitted from October 2004 to December 2008 and all received 3D-CRT with the dosage (50-54 Gy,25-30 f,5-6 weeks).During treatment,the patients’ outcomes were analyzed by observing the changes of symptoms,signs and adverse radiotherapy reaction and all of them were followed-up in the next 3 years.The survival data were analyzed by Kaplan-Meire method.Results The median survival time was 9 months in the 23 pediatric patients and 15 months in 13 adult patients.One-,two-and three-year survival rates between pediatric group and the adult group were 43.5 ％ (10/13) vs 76.9 ％ (10/13),26.1％ (6/23) vs 46.2 ％ (6/13),8.7 ％ (2/23) vs 38.5 ％ (5/13).Karnofsky performance scale score at admission (x2 =20.059,P =0.000),tumor site (x2 =17.585,P =0.000),growth pattern (x2 =21.247,P =0.000) were associate with survival time.Conclusion 3DCRT is an effective therapy to brain stem glioma,childhood onset,pontine glioma,diffusion style and Karnofsky performance scale less than 80 are risk factors of poor prognosis.

AIM: To define the indications of C2 pedicle lag screw or C2 pedicle screw associated with C3 lateral mass screw to treat Hangman fracture, and evaluate the clinical applications. METHODS: Thirty-four patients with Hangman fracture were selected from Changzheng Hospital between February 2000 and December 2004, including 10 patients of type Ⅰ, 12 patients of type Ⅱ, and 8 patients of type Ⅱa, 4 patients of type Ⅲ. Levine-Edwards classification and graded: 2 patients of grade C spinal injury, 12 patients of grade Ds and 20 patients of grade E according to Frankel scale. Patients with typeⅠHangman's fracture were fixed by C2 pedicle lag screw, and patients with typeⅡ, Ⅱa and Ⅲ Hangman fracture were fixed by C2 pedicle screw associate C3 lateral mass screw. Postoperative neurofunctional recovery and fracture healing were studied. RESULTS: A total of 34 subjects were involved in the analysis of results. ① Frankle classification of postoperative neurofunctional recovery: There were 2 cases of grade C, 1 case recovered to grade E, and one case recovered to grade D. There were 12 cases of grade D, including 11 cases of recovered to grade E and one without change. ② In 3-6 months follow-up, X-ray of anterior-posterior and lateral position showed that all fractures healed without loose screw, vertebra artery injury or other complications. CONCLUSION: C2 pedicle lag-screw, C2 pedicle screw associated with C3 lateral mass screw are safe, effective in the treatment of Hangman fracture, which can to retain the function of upper cervical spine as great as possible.
