ObjectiveTo compare the results of controlled- release glipizide and immediate-re- lease glipizide in treating type 2 diabetes mellitus.Methods22 patients took controlled-release glipi- zide as treating group, 20 took immediate-release glipizide as compared. The glucose tolerance, insulin, C- peptide and HbA1c were measured before and after treatment. ResultsBoth of controlled-release glipizide and immediate-release glipizide had good results for controlling blood sugar, but controlled-re- lease glipizide did not increase insulin and C-peptide level. Conclusion The controlled-release glipizide had safe and reliable results for controlling blood sugar and decreasing insulin resistence.

Objective To investigate the relationship between the "prominent laterality of the posterior cerebral artery (PLPCA)" found on magnetic resonance angiography (MCA) and the size and distribution of cerebral infarction and the National Institutes of Health Stroke Scale (NIHSS)scores in patients with occlusion of the M1 segment of the middle cerebral artery (MCA).Methods Fifty patients with acute cerebral infarction caused by the occlusion of the M1 segment of MCA were divided into PLPCA positive group (n =24) and PLPCA negative group (n =26) according to MRA manifestation.the NIHSS scores,size of cerebral infarction scores,and constituent ratios of distribution in all the feeding subregions of MCA in both groups were compared.Results The proportions of the patients with ≥3 risk factors (9/24 vs.18/26,P =0.046),NIHSS scores (5.4 4.4 vs.10.4 ±4.9,t = -3.690,P =0.001),and the size of cerebral infarction scores (1.92 ± 1.10vs.2.88 ± 1.37,t = -3.690,P =0.001) in the PLPCA positive group were significantly lower than those in the PLPCA negative group.The proportions of the patients with cerebral infarction involying the middle branch of the MCA territory (6/24 vs.19/26,P =0.002) and the posterior branch of the MCA territory (2/24 vs.5/26,P ＜0.001) in the PLPCA positive group were significantly lower than those in the PLPCA negative group.The proportions of the patients whose infarction involving the area of the posterior watershed zone were significantly higher than those in the PLPCA negative group (6/24 vs.1/26,P =0.045),and the proportions of complete infarction were significantly lower than those in the PLPCA negative group (0/24 vs.6/26,P =0.023).Conclusions When MCA M1segment was occluded,if PLPCA were observed on MRA,it indicated that the infarct size was smaller and the NIHSS score was lower.The infarction was less involved in the middle and post branches of MCA,and it is prone to have posterior watershed infarction.

0.02 kgf was considered as signifieant.All patients were studied within the first week of presentation with stroke, and underwent every day follow-up within the first month.Results Nine htmdred and fourteen patients were recruited into the study during 1-year period. WECSFP without lesion in brain stem was present in 4.4% of patients within the first week of stroke presentation.The patients with WECSFP had less JFS than the patients without WECSFP(P

Purpose Investigating the significance of ZO-1 different domains in the invasion and metastasis of gastric carcinoma (GC).Methods A tissue microarray that simulates the invasion and metastasis process of GC was created,and immunohistochemistry was performed to detect the expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5).Results The GC cell exhibited aberrant expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5) from membrane translocated to cytoplasm or no expression.The aberrant degree was increased with the invasion,however,was decreased in metastatic lymph node.The aberrant expression was associated with histological types.Conclusion The aberrant expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5),from membrane translocated to cytoplasm or no expression suggest that domains of PDZ3,GUK,SH3,ZU5 and alpha motif in ZO-1 might be involved in the invasion and metastasis of GC and maintaining of GC phenotype.The aberrant expression of these domains may be the one mechanism of ZO-1 involved in EMT or MET.

OBJECTIVETo explore etiologic fraction (EF) and interaction of hepatitis B virus (HBV) infection and other risk factors for primary hepatocellular carcinoma (PHC) in Guangxi, China.

METHODSA hospital-based case-control study including 500 PHC patients and 500 nontumorous patients was carried out in Guangxi. EF and interactions of HBV infection and other risk factors for PHC were analyzed by crossover analysis and nonconditional multiple logistic regression.

RESULTSHBV infection, family history of PHC, diabetes mellitus, eating raw fish, heavy alcohol consumption, frequently used drug, low income, mental oppression and blood type B all were risk factors for PHC. With EFs of 0.725, 0.186, 0.119, 0.486, 0.385, 0.438, 0.277, 0.607, 0.299, respectively and with etiologic fractions attributable to interaction [EF(A xB)] of 0.736, 0.643, 0.849, 0.551, 0.592, 0.618, 0.902, 0.577; and indices of interaction of 0.743, 0.651, 0.853, 0.560, 0.600, 0.626, 0.907, 0.586, respectively.

CONCLUSIONMain risk factors for PHC might include HBV infection, family history of PHC, diabetes mellitus, eating raw fish, heavy alcohol consumption, frequently used drug, low income, mental oppression and blood type B. HBV infection with other risk factors might exert synergistic action on developing PHC and increase the risk of PHC.

Objective： The current study was designed to analyze the differentially expressed genes in nasopharyngeal carcinoma (NPC) tissue and identify the novel oncogenes and the tumor suppressor genes associated with NPC pathogenesis. Methods： Using the suppression subtractive hybridization (SSH), two SSH pools (normal nasopharyngeal tissue cDNA pool and NPC tissue cDNA pool) were constructed. Positive clones were screened by differential screen technique,and conformed using Southern blot and Northern blot, and sequenced with ABI 377 DNA sequencer. Results： Twelve positive clones were identified from SSH pools. Sequences of the 12 positive clones showed that 8 clones were homologous with the genes published in GenBank and 2 clones were unknown genes. The two novel genes NP5 and NP9 in the normal control cDNA pool were richer than that in the cancerous cDNA pool and NP9 was further found to be down regulated in both NPC cell lines and NPC tissue. Conclusions： The SSH is useful for analysis of the disease related genes and two novel cDNAs were identified to be related with NPC pathogenesis.

OBJECTIVETo analyze the differential protein expression of left-sided colon cancer and right-sided colon cancer.

METHODSTissue samples of left-sided colon cancer (n=7) and right-sided colon cancer (n=7) were collected. Tissue protein was abstracted and two-dimensional gel electrophoresis (2-DE) was used to examine the gel images. Peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching with bioinformatics. Immunohistochemical SP method was used for the detection of glucose regulated protein 78 kD (GRP78) and heat shock protein 20 (HSP20) in left-sided colon cancer (n=50) and right-sided colon cancer (n=50) tissues.

RESULTSSixteen differentiating protein spots were identified. Compared with right-sided colon cancer, 10 proteins including GRP78 up-regulated and 6 proteins including HSP20 down-regulated in left-sided colon cancer. Immunohistochemical detection showed that in left and right sided colon cancer, the positive expression rate of GRP78 was 78% (39/50) and 56% (28/50) and the positive expression rate of HSP20 was 34% (17/50) and 72% (36/50), respectively, and the differences were statistically significant (both P<0.05). The positive rate of GRP78 was associated with tumor differentiation, infiltration layer, TNM staging, lymph node metastasis, and liver metastasis, while the positive rate of HSP20 was associated with tumor gross morphology, TNM staging, and lymph node metastasis (P<0.05).

CONCLUSIONSThere are differentially expressed proteins between left-sided colon cancer and right-sided colon cancer, especially for GRP78 and HSP20, which may be the cause leading to the biological differences between left-sided and right-sided colon cancer.
