Objective To evaluate the prognosis of tongue carcinoma surgery with preservation of the integrity of mandible and dentition .Methods Sixty four cases of tongue carcinoma surgery from January 2009 to January 2011 were randomly collected (sev‐en missed ,57 enrolled) .Through retrospective case‐control study on retention of mandibular dentition and mandible rectangle radi‐cal operation of tongue carcinoma radical operation of tongue cancer resection were analyzed the clinical data including the survival rate ,reoccurrence rate and post‐operation life quality .The questionnaire was conducted by fourth edition of UW‐QOL .Results There were no significant difference in survival rates of the two groups of patients between retaining the mandible and dentition and resection of mandible rectangle (P>0 .05) .Two different types of surgical procedures for treatment of jaw had no correlation with the reoccurrence rate (P>0 .05) .The quality of life in retaining the mandible and dentition was significantly higher than the rectan‐gular groups (P<0 .05) .Conclusion Under a strict choice of surgical indications ,preserving radical operation of tongue carcinoma of the mandible and dentition could achieve good results of surgical treatment ,and can significantly improve patients′quality of life after operation .

BACKGROUND: To summarize the feature and clinical application of various injectable bone substitutes.DATA SOURCES: The computer-based research was done in Pubmed database for articles concerning various injectable bone substitutes published from January 1995 to May 2009 with the key words of "injectable bone substitute, bone injury" in titles and abstracts. Literatures of the same fields published in recent years or in authorized journals were selected.DATA SELECTION: Latest literatures addressing feature and clinical application of various injectable bone substitutes were selected; old and repetitive studies were excluded. Finally, 21 articles were included.MAIN OUTCOME MEASURES: Feature and clinical application of various injectable bone substitutes were measured.RESULTS: Present various injectable bone substitutes contained complex hydroxyapatite bone substitutes, complex calcium sulfate bone substitutes, and complex calcium phosphate bone substitutes. Addition of bone morphogenetic protein-2 etc. in injectable bone substitute could significantly elevate bone union speed, promote osteoblastic proliferation, and overcome disadvantage of physical bone substitute to some degrees. Addition of platelet-rich plasma could promote repair effect of injectable bone substitute on bone defects, and promote differentiation of bone marrow stromal stem cells and proliferation of osteoblasts. Addition of cells could make up the insufficiency of physical materials to great degrees.CONCLUSION: The compound injectable bone substitute has a bright perspective of clinical application. Injectable bone substitutes combined with cells (especially stem cells) will be a new direction for biomaterial development in the future.

Objective To observe the application effect of mental nursing on perioperative nursing of patients. Methods 66 patients with cutaneous carcinoma were randomly divided into the conventional nurs-ing group and the psychological intervention group. The conventional nursing group received perioperative mu-fine nursing,the psychological intervention group was given mental intervention before,during and after operation based on routine nursing. The anxiety value was measured before and 30 minutes after the operation, pain de-gree was assessed 30 minutes after the operation,the results underwent t test and X2 teat. Results Compared to the conventional nursing group, the anxiety value before the operation and 30 minutes pestoperation as well as pain degree 30 minutes pestoperation of the psychological intervention group were significantly decreased. Conclusions Mental nursing of patients with cutaneous carcinoma can efficiently eliminate or re-duco patients' psychologic obstacle and significantly reduce patients' painful feeling.

As a tool, cholelithiasis animal models have become an important platform for pathogenetic, preventative, diagnostic and therapeutic research. As biliary calculus formation has a close relationship with dysfunction of hepatic and biliary systems, inability of lipid metabolism homeostasis and impairment of immunologic barriers, increasing studies have been carried out with the use of animal models in these fields. Animal genetic susceptibility to cholelithiasis has greatly attracted people's attention in recent years and cholelithiasis animal models have been used in Chinese traditional medicine development and authentication. Furthermore, reports on invasive and traumatic research have been published in which large animal models were used. It is supposed that technical progress and scientists' demands would result in wide application of more kinds of cholelithiasis animal models.

Objective To investigate the effect of nutrition support therapy on quality of life in patients with advanced tumors.Methods 70 patients with advanced tumors were randomly divided into the observation group and the control group,each group had 35 cases.The control group was given conservative treatment,together with the ordinary liquid,semi-liquid or diet.The observation group was given nutrition support therapy on the basis of conservative therapy.The nutrition and immune index and symptom score,quality of life were compared between the two groups.Results The nutrition,immune indexes (Alb,BMI and NK) and symptom score (malaise,anorexia,insomnia,pain) of the observation group were significantly improved(t =7.92,6.98,5.56,7.41,6.47,5.61,4.52,all P ＜ 0.05),which were significantly better than those of the control group(t =4.42,4.10,4.03,6.42,5.60,4.83,4.23,all P ＜0.05).The physical function,role function,emotional function,cognitive function score and total score of the observation group were significantly higher than those of the control group,the differences were statistically significant (t =8.12,6.08,5.12,4.78,4.32,all P ＜ 0.05).Conclusion Nutrition support therapy can improve the nutritional status of cancer patients in advanced stage,relieve symptoms,improve immune function and quality of life,which is worthy of clinical application.

Gastrointestinal stromal tumors(GISTs) are rarely one of gastrointestinal carcinomas that originate from mesenchymal tissue.GISTs are characterized by expression of CD117 receptor in cells and have variable biological phenotypes ranging from benign to highly malignant.The most common complaints of patients with GISTs are abdominal pain,peptic ulcer,bleeding or/and obstruction in digestive tract.GISTs have an extraordinarily high rate of recurrence after surgical resection and are highly resistant to radiation and standard chemotherapy.The imatinib mesylate(Gleevec) is a selective inhibitor of the tyrosine kinase receptor.The outcome for the patients with GISTs treated by Gleevec was promising in terms of immediate response and survival fraction.Recent research shows that a new targeting therapeutic agent,SU11248,can prolong the survival time of the patients with GISTs who were resistant to Gleevec therapy.

AIM: To explore the effect of acute and chronic hypoxia on the chemotaxis of polymorphonuclear leukocytes(PMNs) of rats.METHODS: Serum and PMNs were separated from rats under normoxia, acute hypoxia and chronic hypoxia condition,and cell aspiration technology system was used to determine the chemotactic migration of pseudopod of PMNs induced by serum as chemotactic factor.RESULTS: Induced by autoserum,the length of pseudopod of PMNs migrated into micropipette [(1.200?0.178)?m,(1.094?0.164)?m ]under acute hypoxic and chronic hypoxic condition was significantly longer than the corresponding value for control[(0.914?0.156)?m,P

Objective Through detected the expression degree of Lin28b in three different malig-nant degree pancreatic cancer cell lines and human pancreatic cell line to study the relationship of pancreatic cancer and the express of Lin28b.Methods The RT-PCR was used to detect the expression degree of mR-NA in Lin28b in cell lines of PANC-1,BxPC-3,AsPC-1,HPC-Y5 and Western-blot was used to detect the expression degree of protein in Lin28b in cell lines of PANC-1,BxPC-3,AsPC-1,HPC-Y5,then discovering the differential expression.Results The Lin28b was high expression in three pancreatic cancer cell lines, also higher than human pancreatic cell lines,and the expression of difference had statistical significance. Conclusions The results suggested that Lin28b may play a role in the pathogenesis of pancreatic cancer, and there is a certain relationship between the expression of Lin28b and malignant degree of tumor cells.
