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 .

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.

Aim To examine subcellular localization of serotonin 5-HT2A receptor (5-HT2AR) and glutamate NMDA receptor in dorsal hippocampal CA1 area ( dCA1 ) and further explore the effect of systemic acti-vation of 5-HT2A R on hippocampal neuronal firing rate. Methods The distribution of 5-HT2A R and NMDA re-ceptor in the dCA1 region was detected with immune e-lectron microscopy after embedding. The effect of acti-vation of 5-HT2A R on the principal neuron and inter-neuron firing rates was examined with multichannel re-cording. Results 5-HT2A R immunoreactivity was ob-served in the dCA1 neurons, including rough endoplas-mic reticula and mitochondria, and the 5-HT2A R and glutamate NMDA receptors were colocalized in the syn-aptic membrane, vesicle and neurofilament of the hipp-ocampal neuron. 5-HT2A R activation increased princi-pal neuronal firing rate and the interneuronal firing rate was not changed. Conclusion The 5-HT2A R and NM-DA receptor are colocalized in dCA1 neurons, and acti-vation of 5-HT2A R increases hippocampal principal neuronal firing rate.

Objective:To investigate the operation technique and the effect of the posterior microendoscopic discectomy (MED) system on lumbar intervertebral disc hermiation (LIDH). Methods: We retrospectively reviewed and analyzed 25 cases of LVDH treated with the MED system from March 2004 to August 2005. Results: All the patients were ambulant 20 hours to 7 days (mean 2.4 days) after the operation, with a mean hospital stay of 5.2 days. And all were healed within the first stage except 1 case of infection. The patients were followed for 2-15 months (mean 6 months). Excellent results were achieved in 18 cases, good results in 5 and fairly good results in 2, the first two groups making up 92%. Conclusion: The key to successful MED with no complications is familiarity with the equipment, proper choice of indication, exact surgical location and skilful operation.

We have reformed the traditional pathophysiological experimental teaching from improving experimental teaching method,optimizing experimental content,updating experimental teaching material,starting design experimental and founding general examine system.

Rectal cancer is a common malignant tumor in the gastrointestinal system.For the patients with resectable but high-risk rectal cancer,neoadjuvant and adjuvant chemoradiation plus surgery may improve local control.Compared to adjuvant chemoradiation,neoadjuvant chemoradiation showed the advantage of sphincter preservation.When the goal of preoperative chemoradiation was sphincter preservation,conventional radiotherapy was recommended.Through the analysis of the patients with 5-year survivals,the radiation had a similar impact on the survival as the chemotherapy alone for the patients with the intermediate risk factors.The impact on local control need to be further investigated before recommending chemotherapy alone for those subset patients.Advances in preoperative irradiation,postoperative irradiation and the comparison of preoperative irradiation with postoperative irradiation are also reviewed in this article.

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.

The multi drug resistance(MDR) of tumor cells has become a difficult problem in the chemotherapy of tumor, meanwhile, the mechanism of MDR are various:relevant drugs with reversal effects have been discovered. This review will provide the most impossible mechanisms of MDR and some prospecting reversal drugs.

Objective: To study the scavenging capacity of extract from four kinds of barley leaves on superoxide free radical and hydroxyl free radical. Methods: Measure the content of superoxide free radical and hydroxyl free radical by nitro blue tetrazolium(NBT) photo-reduction. Results: Along with the flavonoid in the reaction liquid, the scavenging rate shows ascending trend . When the concentration of flavonoid is 12?g/ml, its scavenging rate is 95.56% and 94.12% on superoxide free radical and hydroxyl free radical respectively. Conclusion: The flavonoids of barley leave s have stronger anti-oxidative action.
