1.On the Medical Ethical Significance of Charity Philosophy
Chinese Medical Ethics 1994;0(05):-
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

Full ceramic prosthesis is becoming the main prosthetic development direction. As an important kind of full ceramic prosthesis, full ceramic veneer has not only natural cosmetic appearance and perfect biocompatibility, but also can preserve tooth structure as much as possible, which would be more easily accepted by patients for cosmetic prosthesis. Many methods, such as slip casting, die casting and CAD/CAM technology are available to make full ceramic veneer. All the methods have their own advantages and disadvantages. Slip casting is easy to be developed widely with low cost, so be used in practical work. In this article, the working process of full ceramic veneer, especially manufacture of removable dies, duplication of refractory models, were introduced, which was supposed to be beneficial for the technicians.

AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

AIM: To study the influence of ginkgolides on expression of inducible nitric oxide synthase (iNOS) in rats. METHODS: Middle cerebral artery occlusion(MCAO) model was induced by ligating internal carotid artery of Sprague Dawley(SD) rats.In this model,the behavioral deficits performance of SD rats was analyzed after given ginkgolides and nimo dipin, respectively, and iNOS gene expression changes in MCAO group were investigated. RESULTS:The expression of iNOS was increased in MCAO models and inhibited in ginkgolides groups. CONCLUSION:Ginkgolides have inhibitive efficacy of iNOS on cerebral ischemia and can reduce brain damage.
