Objective To study the relationships among the expression of inhibitors of DNA binding 1 (ID-1) , Ki-67 and Bcl-2 in esophageal squamous cell carcinoma (ESCC) ,and to investigate the potential role of ID-1 in the carcinogenesis of ESCC. Methods One hundred and eighteen cases of surgical resected ESCC specimens and 20 cases of normal tissues ( sampled far from the tumors, as control) were involved. Immunohistochemical technique was applied to detect the expression of ID-1, Ki-67 and Bcl-2. Results The positivity and staining intensity of ID-1 , Ki-67 and Bcl-2 in ESCC were higher than those in normal tissues. Positive immunological reactions of ID-1, Ki-67 and Bcl-2 were found in 86.44% (102/118) , 81.36% (96/118) and 59. 32% (70/118) cases of examined tumor samples, respectively. The expression of ID-1 and Bcl-2 were positively correlated with the histological grades, while the Ki-67 expression showed negative correlation with differentiation degree. No relationship was found among age, sex, lymph node metastasis and the expression of ID-1, Ki-67 and Bcl-2 in ESCC tissues. Conclusion ID-1 expression may be participated in the regulation of apoptosis in ESCC cells, but may not be considered as a biomarker for evaluation of ESCC metastasis.

Objectives To investigate the effects of glucose on apoptosis rate of cultured endothelial progenitor cells (cEPCs). Methods The peripheral blood of healthy adults was isolated by density gradient centrifugation, and mononuclear cells (MNCs) were inducted to differentiate at cultured conditions.EPCs were identified by Dil-acLDL and FITC-UEA-1 as double fluorescent-positive cells. The effectsof glucose at different concentrations on apoptosis rate of the harvested EPCs were measured by fluorescent microscope and fluorescence-activated cell sorting (FACS) after staining with Annexin V-FITC and PI. Results No significant differences were observed in apoptosis rate between samples treatedwith 5.6mmol/l glucose and 11. 1 mmol/l. P >0. 05). 25.5 mmol/L glucose enhanced the EPCsapoptosis rate in a time-dependent manner( P <0. 05). Conclusion High concentration glucose can accelerate apoptosis rate of EPCs in a time-dependent manner.

Objective:To analyze the changes in T lymphocyte subsets, B lymphocytes and NK cells in children with active tuberculosis (TB) and their clinical significance.Methods:T lymphocyte subsets, B lymphocytes and NK cells in peripheral blood samples of 106 patients with acute TB (TB group) and 106 healthy children (healthy control group) were detected by flow cytometry and compared between different groups.Results:The percentages of CD3 + T, CD4 + T and NK cells as well as the CD4 +/CD8 + T cell ratio were significantly lower in the TB group than in the healthy control group ( Z=-3.783, P=0.000; Z=-5.401, P=0.000; Z=-3.434, P=0.001; Z=-2.014, P=0.044). The percentages of double negative T (DNT) and B cells in the TB group were significantly higher than those in the healthy control group ( Z=2.765, P=0.006; Z=6.880, P=0.000). No significant difference in the percentage of CD8 + T or double positive T (DPT) cells was observed between the two groups ( P>0.05). The expression of peripheral lymphocyte subsets varied in TB children of different age groups (0-<3, 3-<6, 6-<10 and 10-<16 years old). There were significant differences in CD3 + T, DNT and B cells among the four age groups ( H=10.081, P=0.018; H=14.583, P=0.002; H=8.498, P=0.037). The percentage of CD4 + T cells was significantly lower in children with extrapulmonary TB than in those with pulmonary TB ( Z=-3.068, P=0.002). No statistically significant difference in other lymphocyte subsets was found between children with extrapulmonary and pulmonary TB ( P>0.05). Conclusions:Tuberculosis could lead to immune dysfunction in children. Dynamic monitoring of the changes in peripheral lymphocyte subsets in children with TB could be conducive to better assessment of immune status and providing personalized treatment.

In four patients with chronic pancreatitis from two hereditary pancreatitis (HP) families and 63 normal controls, five exons of cationic trypsinogen gene (PRSS1) were amplified by PCR and it's products were analyzed by sequencing, related clinical data were also collected. All the four patients were found mutations in the PRSS1 gene but their clinical feature is absolutely different. Six patients with diabetes mellitus were found in pedigree No. 1, it's members show pancreatitis symptom later, at about 29, the tumor markers (CA19-9, CA72-4) is obviously higher than the patients in pedigree No. 2, two patients with chronic pancreatitis in pedigree No. 2, show symptom earlier without diabetes mellitus, their clinical characterization are different too. The number of CD4+T cell/CD8+T is very low in Ⅲ 8, but Ⅲ 7 is normal, and the level of anti-HBs of Ⅲ 8 is variable in the course of pancreatitis, but the phenomenon was not found in Ⅲ 7. In their PRSS1 gene two guanosine (G) to adenosine (A) mutations were found in PRSS1 exon 3 of pedigree No. 1, one was detected at 336 basyl, the other mutation occurs at 361 basyl. The results of the mutations were Lys →Lys and Ala →Thr. While thymine (T) to adenosine (A) and (guanosine) G→(adenosine) A mutation in PRSS1 exon 3 was detected in the other patient of pedigree No. 2 (Ⅲ 8). One was 361 basyl, the other at 415 basyl. While c.415 T→A was not found in the proband of pedigree No. 2 PRSS1 gene (Ⅲ 7). All of the mutations were heterozygous mutation, that is to say all of the trypsinogen were wild type and mutant type concomitance, the normal and abnormal pathway of active trypsinogen exist partially. At the same time, the mutations of SPINK1 were not observed. Compared with the documents and registration of NCBI, it can be concluded that PRSS1 gene had many kinds of mutations in hereditary pancreatitis, the heterozygous mutations (c.336 G→A, c.415 T→A) were the novel mutations and related with clinical phenotype. What's more, it's the first time that the multisite heterozygous mutations of PRSS1 gene were reported. The presence of the mutations in four patients with chronic pancreatitis, it's absence in their relatives and the strong evolutionary conservation of the mutation, all indicate that the trypsinogen mutation is associated with hereditary pancreatitis and for the first time raises the question whether a gain or a loss of trypsin function participates in the onset of Chinese pancreatitis.

Objective To investigate the role of astroglial glutamate-glutamine shuttle in the development of neuropathic pain (NP) in rats. Methods Forty-eight adult male SD rats weighing 200-230 g were randomly divided into 8 groups (n =6 each): Ⅰ control group (group C);Ⅱ sham operation group (group S);group ⅢNP;Ⅳ-Ⅶ 0.01, 0.03, 0.05 and 0.10 mmol/L methionine sulfoximine (MSO, an inhibitor of glutamine synthetase (GS)) group (group M1-4 );Ⅷ MSO + glutaminate group (group MG). In group C no operation was performed. In group S the sciatic nerve was only exposed but not ligated. NP was induced by ligation of the tibial nerve and commom peroneal nerve according to the technique described by Dixon. After the establishment of the model, intrathecal PBS 50 μl was injected in group NP, IT 0.01, 0.03, 0.05 and 0.10 mmol/L MSO 50 μl was injected intrathecally in group M1-4, and 0.05 mmol/L MSO 50 μl was injected intrathecally and then 0.25 mmol/L glutamine 50 μl was injected intrathecally 15 min later in group MG. Mechanical pain threshold was measured 1 week before ligation (T0 , baseline), 1 week after ligation (T1) and 15, 30, 45 and 60 min after injection of MSO (T2-5). Then rats were killed and the lumbar segment of the spinal cord was removed for determination of the expression of glial fibrillary acidic protein (GFAP) and GS and the co-expression (GFAP/GS) in the dorsal horn.Results Mechanical pain threshold was significantly lower at T1-5 in group MG and NP and at T2-4 in group M3.4 ,and the expression of GFAP, GS and GFAP/GS was significantly higher in group MG,NP and M3 than in group S and C ( P < 0.05) .Conclusion Astroglial glutamate-glutamine shuttle in the spinal cord is involved in the development of neuropathic pain in rats.

OBJECTIVE:
To explore the effect of systematic self-management education on quality of life, anxiety and depression of patients with Type 2 diabetes in communities.
METHODS:
A total of 248 patients with Type 2 diabetes from 10 communities of Changsha from February 2009 to July 2010 were randomized into an intervention group and a control group. The intervention group received systematic self-management education, while the controls received routine community education. The quality of life, anxiety and depression were measured by adjusted diabetes-specific quality of life scale (A-DQOL), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) respectively.
RESULTS:
The quality of life, morbidity of anxiety or depression of the intervention and the control group were comparable at the baseline (P>0.05). One and half year later, there was significant difference between the two groups (P<0.01). Compared with the control group, the intervention group got better quality of life (P<0.01), less morbidity of anxiety (8.94% vs. 44.4%, P<0.01) and depression (23.58% vs. 56.00%, P<0.01).
CONCLUSION
Systematic self-management education can effectively improve the quality of life, reduce the level of anxiety and depression of patients with Type 2 diabetes in communities, which deserves further generalization.
