Objective To identify the important risk factors for type 2 Diabetes Mellitus (T2DM) and develop effective strategies to address the problem of T2DM.Our study aimed to evaluate the association between apolipoprotein E (ApoE) genetic polymorphism and type 2 diabetes,and to provide clues for the etiology of T2DM.Methods Based on the criteria of inclusion and exclusion,we extracted,pooled,analyzed and assessed the case-control studies of ApoE polymorphism and T2DM published in PubMed,Web of Science,Medline,WanFang,VIP,and CNKI databases by R soft-ware (version 3.4.3).We used Random-effect models when heterogeneity was present in between-study,and fixed-effect models otherwise.Results We had 59 studies covering 6,872 cases with T2DM and 8,250 controls,and compared the alleles and genotypes of ApoE between cases and controls.When we conducted a comparison between ApoE ε4 and ε3 alleles,we produced a pooled OR of 1.18 (95％ CI:1.09-1.28;P ＜ 0.001).ApoE ε2/ε2 genotype displayed a possible association with T2DM (OR =1.46;95％ CI:1.11-1.93;P =0.007),ε3/ε4 genotype showed a 1.11-fold risk (OR =1.11;95％ CI:1.01-1.22;P =0.039) and ε4/ε4 genotype had a 1.71-fold risk of developing T2DM (OR =1.71;95％ CI:1.33-2.19;P ＜ 0.001) when they were compared with ε3/ε3 genotype.Conclusions There is an association between ApoE polymorphism and T2DM:allele ε4 and genotypes (ε2/ε2,ε3/ε4,and ε4/ε4) are associated with the increased risk for the development of T2DM,and they may be risk factors for T2DM.

Severe acute pancreatitis (SAP) is a common acute abdomen clinical problem characterized by high mortality, multiple complications, complicated pathogenesis and difficult treatment. Recent studies found traditional Chinese medicine (TCM)monomers have markedly good effect for treating SAP. Many TCM monomers can inhibit pancreatin, resist inflammation, improve microcirculation and immunoloregulation, etc. to block the pathological progress of SAP in multiple ways, reduce complications and lower mortality with rapid effects. It is significant for enhancing SAP treatment to deeply understand the current situation in TCM monomers for treating SAP and take precious references therein. This article summarizes the treating effects and mechanisms of TCM monomers for SAP in recent years.

OBJECTIVETo explore roles of extracellular signal-regulated kinase (ERK) 1/2, p38 mitogen activated protein kinase (p38 MAPK) and nuclear factor (NF) -KB in expression of inducible nitric oxide synthase (iNOS) in rat alveolar macrophages induced by high mobility group box 1 (HMGB1 ).

METHODSPrimary rat alveolar macrophages (PRAMs) cultured in vitro were incubated with PD98059 ( inhibitor against ERK), SB203580 (inhibitor against p38 MAPK) , PDTC (inhibitor against NF-kappaB), or PD98059 plus SB203580 for 2 hours, respectively. HMGB1 was added into the cultures and incubated with cells for 6 hours. Total RNA of PRAMs was extracted and iNOS mRNA expression was semi-quantified with reverse transcription-polymerase chain reaction ( RT-PCR). Greiss reaction was applied to determine nitrite/nitrate (NO2-/NO3- ) concentration in PRAMs culture supernatants.

RESULTSExpression of iNOS mRNA and NO production in PRAMs culture supernatants were down-regulated by inhibition of ERK or p38 MAPK by PD98059 or SB203580, respectively (P <0. 05). Moreover, inhibition of iNOS expression and NO production was observed after simultaneous pretreatment with PD98059 and SB203580 (P < 0. 05). Expression of iNOS mRNA in PRAMs and NO production in PRAMs culture supernatants were down-regulated by inhibition of NF-kappaB by PDTC (P <0. 05).

CONCLUSIONCellular signal molecules of ERK, p38 MAPK, and NF-kappaB all participate in the expression of iNOS and NO production in PRAMs induced by HMGB1.

OBJECTIVETo describe the clinicopathologic features and immunophenotypes of carcinoid tumorlets in the lung with bronchiectasis, and to study the morphogenesis of these tiny tumors.

METHODSThe histopathologic characteristics of 3 bronchiectasis cases with carcinoid tumorlets, 11 bronchiectasis and 2 normal lungs were studied. Specific markers of the tiny tumors and the number of neuroendocrine cells (NECs) in the airway mucosa were immunohistochemically detected by EnVision method.

RESULTSThe tumorlets in the lungs presented as multi-focal nodules and most were displayed only under microscopy. These cells were arranged in clusters and foci of fascicles which were situated in the surrounding bronchial wall and bronchioles adjacent to bronchiectatic lesion, or in the scar tissues. The tiny tumors were consisted of short fusiform cells and small ovoid cells. Their nuclei were circular, oval or long fusiform and the cells were strongly argyrophilic on Grimelius staining. Intensive positive immunostaining for calcitonin, chromogranin A, NSE and gastrin were detected. Weak positive for CK, EMA, S-100 and focal positive for HC, ACTH, 5-HT were also observed. Proliferative NECs in airway mucosa adjacent to the tiny tumors increased significantly in number, compared with those in the airway mucosa of bronchiectasis without tumorlets and normal lungs (P < 0.001, respectively).

CONCLUSIONSThe clinicopathologic features and immunophenotypes of carcinoid tumorlets resemble carcinoid tumors. They are the early stage of carcinoid development. Their development may be related to the chronic pulmonary damage resulting in hypoxia and stimulating the proliferation of NECs. These pulmonary carcinoid tumorlets can be used as a model to study the tumorigenesis of carcinoid carcinoma of the lung.

OBJECTIVETo investigate the feasibility of detecting cyclin D1 protein expression and t(11;14) chromosomal translocation in paraffin-embedded tissues and its diagnostic and differential diagnostic significance for mantle cell lymphoma (MCL).

METHODSParaffin-embedded samples of 36 cases of MCL and a control group of 71 cases of small B-cell lymphomas were retrieved from archive materials. Immunohistochemical staining for cyclin D1 and semi-nested PCR for t(11;14) were detected in all samples. House-keeping gene beta-actin was used to detect the quality of DNA.

RESULTS(1) Cyclin D1 was expressed in 26 of the 36 MCL (72.2%). There was no cyclin D1 expression in the control group. (2) beta-actin DNA was detected in 101 of the 107 tumor cases (94.4%). t(11;14) was detected in 22 of the 36 MCL. Translocation was not found in control group. The positive rate for t(11;14) was 64.7% in MCL after exclusion of 2 cases which were negative for both t(11;14) and beta-actin. (3) 29 cases were positive for cyclin D1 and/or t(11;14), the positive rate reached 80.5%.

CONCLUSIONThe combined detection of cyclin D1 and t(11;14) in paraffin-embedded tissues is found to be a specific and feasible method for diagnosis and differential diagnosis of mantle cell lymphoma.

Purpose To investigate the expression of Cyclin D2 in diffuse large B cell lymphoma (DLBCL) and its relationship with clinicopathological classification and prognosis. Methods (1) Immunohistochemistry (IHC) of EnVision twostep staining for CD3, CD20, CD10, BCL-6, MUM1, Ki-67 and Cyclin D2 was carried out in 79 cases of DLBCL specimens using tissue microarray constructed from tumor paraffin block.(2) The relative expression of Cyclin D2 mRNA in 79 cases of DLBCL was observed by realtime quantitative PCR (qRT-PCR) in fresh frozen tissue. The relationship between the expression of Cyclin D2 mRNA and survival rate was analyzed by Kaplan-Meier test. Results 79 patients of DLBCL were classified into26 (32.9％) case of germinal center B-cell-like (GCB) sub-types and 53 (67.1％ ) cases of nongerminal center B-cell-like(non-GCB) subtypes. Cyclin D2 protein was expressed in 2(15.4％) cases of GCB subtypes and 11 (84.6％) cases of non-GCB subtypes, respectively. The difference between the GCB subtypes and the non-GCB subtypes was statistically significant (P＜ 0.05). The expression of Cyclin D2 mRNA in non-GCB subtypes was significantly higher than that in GCB subtypes(P＜ 0.05 ). The high clinical stage and the expression of Cyclin D2 mRNA were associated with lower overall survival rate. Conclusion The detection of Cyclin D2 expression can improve the accuracy of clinicopathological classification of DLBCL. The level of Cyclin D2 mRNA may be an important reference for prognosis of DLBCL.

OBJECTIVETo observe the status of AKT and phospho-AKT (pAKT) in three diffuse large B cell lymphoma (DLBCL) cell lines, and to investigate the effects of AKT activation on biologic behavior of DLBCL cells.

METHODSThree DLBCL cell lines, ly1, ly8 and ly10 were maintained in 10% FBS or serum free culture medium. The expression of AKT and status of pAKT were detected by Western blotting. LY294002, an inhibitor of PI3K, was used to suppress the level of pAKT. Flow cytometry combined with PI staining, AnnexinV-FITC assay and Brdu incorporation assay were used to analyze the parameters of the cell cycle, apoptosis and proliferation respectively.

RESULTSThere was constitutive activation of AKT in three DLBCL cell lines and the levels of pAKT were altered in the different environments. In 10% FBS culture medium, pAKT was higher than that in serum free culture medium in ly8 and ly10, however, pAKT in ly1 maintained in serum free culture medium was mildly higher than that in 10% FBS culture medium. When the cell lines ly1, ly8, ly10 were maintained in 10% FBS culture medium, the inhibitor LY294002 suppressed the level of pAKT efficiently in three DLBCL cell lines. The percentage of cells at S phase and the proliferation index were significantly decreased (P < 0.05) without an increase of apoptosis (P > 0.05).

CONCLUSIONSActivation of AKT may play an important role in the development of DLBCL. It is closely related to the control of cell cycle and proliferation, but is not associated with apoptosis. LY294002 can inhibit cell growth by decreasing the levels of pAKT in DLBCL cell lines.
