Objective To discuss the treatment of cranialfacial fibrous dysplasia. Methods The treatment of 10 cases of cranialfacial fibrous dysplasia was analyzed. Results The cosmetic deformity was corrected in all the cases.No new symptom of nervous system occurred. Conclusion It is important to carry out the correct surgical plan according to patients' age,location,mono-or poly-ostotic form of fibrous dysplasia,presence or absence of functional limitations,and aesthetic problem.

The contents of the individual fractions of glucose oligosaccharides were determined simultaneously by means of reversed-phase HPLC. The sample was dissolved in water and filtered and the filtrate was used directly for the analysis. The sugar was separated on a column of u-Bondapak C18 using water as the mobile phase and determined refractometrically.The method was applicable to the analysis of glucose oligosaccharides from monomeric glucose through polymeric maltooctose. Quantitative results were obtained for glucose, maltose, maltotriose, maltotetrose, maltopentose and maltohexose in the samples prepared in our laboratory. Recovery tests revealed this method reliable.

Hepatitis C virus(HCV)is the major etiology of non-A,non-B hepatitis.At present,neither a vaccine nor any effective therapy is available.Multi-epitope DNA vaccine(minigenes/epigenes)is a novel nucleic acid vaccine which can induces high effective cellular and humoral immune responses and has good perspective in clearing Hepatitis C virus through screening and assembling optimal antigen epitope genes(T cell、B cell epitope included).It is advanced in covering more HCV subtypes,inducing comprehensive anti-HCV immune responses and reducing the negative influence caused by irrelevant,disturbing and suppressive sequence as far as possible through selecting the most potential protective epitopes in DNA vaccine design.The recent research progress on HCV compound multi-epitope DNA vaccine and future prospects were reviewed.

Objective To evaluate the safety and feasibility of hepatic resection for huge primary liver carcinoma (PLC). Methods 216 cases of huge PLCs(mean diameter of 14.2cm) were resected. The hepatectomies were performed under intermittent occlusion of hepatic inflow. Results All 216 cases were successfully resected. The mean time of occlusion of hepatic inflow was 19min, the mean blood loss was 743 ml. No serious complications occurred, and only seven patients died of hepatic failure and upper gastrointestinal haemorrhage postoperatively in this series. Conclusions Although resection of huge PLC is quite difficult, but if suitable surgical techique and perioperative management are adopted ,it is safe and feasible .

Objective:To learn the effect of personality in the course of cognitive decline.Methods:106 aged people from two districts were selected randomly.Arithmetic,digit span,picture filling,block patterns,digit symbol,visual attention span,spatial reasoning were used to learn the cognitive ability,“Kartaier's 16 personality factors test”were used to explore the personality of aged people.Results:16 personality factors test shows that old people are more deferential and self-assured.The relation between reasoning and arithmetic,rule-consciousness and arithmetic,abstractedness and digit span,reasoning and block design,dominance and digit symbol,sensitivity and special reasoning,apprehension and visual attention span,openness to change and visual attention span reach the statistical significance.Conclusion:Age is the most important reason to the cognitive impairment in aged people, education can prevent the cognitive impairment in a large degree.Personality can affect the cognitive ability although different personality factor affect different cognitive fields.

ObjectiveTo observe the effect of rat cerebral hemorrhage model via autologous blood injection.MethodsBlood extracted from rats' cardiac ventricles was injected into the right caudate nucleus via stereotactic method. Pathological examination,ultrastructural visualization and motor functional test were applied to validate the feasibility of this method.ResultsRats showed paralysis of left extremities rapidly after surgery. Pathological examination confirmed the formation of hematoma in caudate nucleus. The deviation of hematoma volume and location among individuals was significantly lower than that of rats made by collagenase injection. Transmission electron microscopy showed wide mylin degeneration in right caudate nucleus. Motor functional test revealed the dysfunction of left extremities with marked lower deviation among individuals compared with that of collagenase injection (P<0.05).ConclusionAutologous blood injection can result in significantly lower deviation of hematoma volume and location as well as dysfunctional degree compared with that of collagenase injection.

Objective To learn the effect on carcinoma xenograft in nude mice by inhibiting human papillomavirus 16(HPV16) E6 gene expression in CaSki cell. Methods The recombinant plasmids expressing HPV16 E6 small interference RNA (siRNA) were transfected into CaSki cell. The cells expressing recombinant plasmid was screened out with G418. The expression of E6 mRNA was determined by RT-PCR. The cells were inoculated into BALB/c nude mice subcutaneouly and the growth of the xenograft carcinoma was observed. After the pGensil-CH2 recombinant was injected into the carcinoma, the growth of carcinoma and pathological changes of carcinoma were observed. Results The CaSki cell expressing E6 siRNA was obtained, and HPV16 E6 mRNA expression in CaSki cell was down-regulated. The oncogenicity of the CaSki cell expressing E6 siRNA was degraded, the inhibition rate was up to 71.4% as compared with that of control group. The growth of tumor in nude mice was inhibited after the E6 siRNA plasmids were injected into the nude mice. The volume and weight of the tumor treated by siRNA were smaller than that of control group significantly. More necrotic area and less cell division phase were observed under light microscope in the E6 siRNA treated tumor. Conclusion The oncogenicity of the CaSki cell was degraded after silencing HPV16 E6 gene in CaSki cell by E6 siRNA.

Objective: To explore the effect of Fuzheng granules on immune function activities in animal models.Methods: The effects of Fuzheng granules were investigated in normal mice and immunosuppressive mice by macrophage englobement rate and index of phagocytosis,leucocyte quantity,lymphocyte conversion ratio induced by adhesin,serum hemolysin,content of serum con-complement.Results: Fuzheng granules could significantly elevate the macrophage englobement rate,index of phagocytosis,leucocyte quantity,lymphocyte conversion ratio induced by adhesin,serum hemolysin,content of serum con-complement in above mice.Conclusion: Fuzheng granules had the effect of improving immune function activities.
