Objective To study the expression level of PKM1 and PKM2 in colorectal cancer tissue and explore the relationship between colorectal cancer progression and their expression level.Methods The PKM1 and PKM2 protein expression levels in colorectal cancer tissues and adjacent tissues to carcinoma were determined by Western blot and Immunohistochemisty method, and the relationship with colorectal cancer were discussed. Results Western blot and Immunohistochemisty results all showed that, compared with adjacent noncancerous, the protein level of PKM1 decreases significantly in cancer tissues (P<0.05), while the protein level of PKM2 increases significantly in cancer tissues (P<0.05).The protein level of PKM1 is not relative with age,sex and stage of patients, but the protein level of PKM2 is relative with pTNM(P<0.05).Conclusion Colorectal cancer tissues with low level of PKM1 and high level of PKM2, and PKM2 was related with TNM of patients.

Objective Comparing the serum fingerprint of four kinds of extract solution from Banxia Baizhu Tianma Decoction.Methods Taking rabbits as experiment animals,collecting blood,and separating serum after drenching semi-bionic enzyme extracting(SBEE) solution.HPLC was used to detect the fingerprints of medicated serum at different blood-collecting time in order to optimize the best blood collecting time,then the serum fingerprints of four kinds of solution collected were compared.Results HPLC showed that when blood collecting time was 2 h,the number and total area of chromatographic peak had the maximum value;SBEE Solution had the the maximum number and total area of chromatographic peak in the four kinds of solution at the best blood collecting time.Conclusion The component content in SBEE medicated serum is higher than that by other method.

Objective To explore the positive effects of dancing train to self-esteem and social function in chronic schizophrenia patients.Methods By random sampling,40 male and 40 female chronic schizophrenic inpatients with dancing train were enrolled as the research group in our study training.According to gender,age,education,diagnosis,hospital stays and other factors,80 inpatients without dancing train were enrolled as the control group by paired choice.Both groups were evaluated with Self-esteem Scales (SES) and Scales of Social Practice of Inpatients (SSPI) at pre-and post-training.Results Comparison between the research group and control group showed that it had no significant difference between every value of scales in male and female before training; after training the research group's every indicants was better than that of the control group,and there were significant differences.Compared between pre-and post-training,the research group had significant differences but the control group did not.Before training,no significant differences between male and female of the research group.Compared with male inpatients,females achieved significantly better scores in SES,SSPI and 2 items of daily living and positive social communication after dancing train for 8 weeks.There were significant differences between male and female inpatients in SES,SSPI and 3 items of SSPI at pre-and post-train.Conclusions Dancing train can be effective to the residue symptoms in schizophrenic patients and improve social function and self-esteem of male and female inpatients.

AIM：Damaging of Endothelial cells and adhesion of leukocytes and platelets were studied in rat mesentery microvessels after ischemia-reperfusion.METHODS：The model was made by losing blood and reperfusion from carotid artery in rat. Changes in mesentery microvessels were observed by high magnify microscope.RESULTS:Leukocyte and platelet adhesions were found in venules and co-capillaries 1-3 hours after ischemia-reperfusion. Endothelial cells were edema and vascular walls were thickening. Vacuoles formed in intracytoplasm of some vascular endothelium and some bigger endothelial vacuoles prominenced toward the luminal surface. Vacuoles had the shape of circle and the diameter was 10-30 μm. More vacuoles were found in arterioles, even there were several vacuoles in a arteriole. The biggest vacuole almost occupied 2/3 of vascular lumen.CONCLUSION：Edema and vacuole formation in vascular endothelium showed endothelial cells were damaged seriously after ischemia-reperfusion.

Objective:To detect the expressions of survivin, galectin-3 and thyroid peroxidase in papillary thyroid microcarcinoma ( PTMC) and cancer adjacent normal tissue to explore the clinical significant.The correlations between the expressions of survivin,Gal-3 and TPO with BRAFV600E gene mutation in PTMC were analyzed.Methods: The expressions of survivin,Gal-3 and TPO were measured by immunohistochemical ( IHC ) method in 56 cases of PTMC tissue and adjacent normal tissue; BRAFV600E mutation was detected by PCR amplification and subsequently sequencing.Chi square test was used to analyse the relation in the expression rates of survivin,Gal-3 and TPO and BRAFV600E gene mutation.Results:The survivin and Gal-3 were strongly expressed but TPO was negatively expressed.The survivin and Gal-3 were negative in adjacent normal tissues but TPO was expressed.There were sig-nificant differences in the expression rates of survivin, Gal-3 and TPO between PTMC tissue and adjacent normal tissue (all P<0.001).The BRAFV600E mutation rate (32.1%) and the expression rates of survivin,Gal-3 and TPO in PTMC tissue were found to be positively related to lymph node metastases (P=0.009,P=0.025,P=0.007,P=0.008),and negatively related to gender and age (all P>0.05).There were no correlation was found between the expressions of survivin,Gal-3,TPO and the BRAFV600E gene mutation in PTMC(all P>0.05).Conclusion: The strong expressions of survivin and Gal-3,the mild expression of TPO and BRAF mutation may be important in the development of PTMC,and the detection of BRAFV600E gene mutation and the expressions of survivin, Gal-3 and TPO could be used to the judgment of pathogenetic condition and prognostic outcomes.

Objective:To investigate the sensitivity and the specificity of scorpions amplification refractory mutation system ( ARMS) in comparing with that of direct DNA sequencing in the detection of BRAF gene mutations in patients with papillary thyroid microcarcinoma.Methods:Direct sequencing and ARMS were used simultaneously to detect BRAF mutation status in 56 patients with PTMC.Results:BRAF mutations were identified in 46 cases with a mutation rate of 82.9%by ARMS,while in 18 cases with a mutation rate of 32.1%by direct sequencing.Besides,the sensitivity of ARMS was 100%and that of direct sequencing was 39.1%.There were significant differences of both mutation rate and sensitivity between two methods ( P<0.01 ).Conclusion: Compared to direct sequencing,ARMS gains a higher sensitivity in the detection of BRAF mutations in samples with tiny lesions.
