Gliclazide used for the treatment of type 2 diabetes mellitus (T2DM) stimulates insulin secretion and influences peripheral blood monocytes.The roles of gliclazide in peripheral monocytes of newly diagnosed T2DM patients were investigated in this study.A total of 105 newly diagnosed T2DM patients with no history of antihyperglycemic medication were treated with gliclazide-modified release for 16 weeks.The total and differential leukocyte profiles of peripheral blood were measured at baseline and week 16.The peripheral blood monocyte count at week 16 was significantly lower than that at baseline (P=0.019).Peripheral monocytes level at baseline was positively correlated with waist circumference.After gliclazide treatment,the peripheral monocytes were decreased [(320.09±15.13)×106/L vs.(294.19±14.22)×106/L] in non-abdominal obesity group,but increased in abdominal obesity group [(344.36±17.24)×106/L vs.(351.87±16.93)×106/L].Compared with non-abdominal obese patients,abdominal obese patients showed higher Amonocytes (P=0.046) and Aacute insulin secretion (P=0.049),but lower AHbAlc (P=0.047).There was significantly positive correlation between Amonocytes and Aacute insulin secretion (P=0.015),which disappeared after adjusting for age,waist circumference and dosage at baseline.In conclusion,waist circumference is correlated with peripheral monocyte change after gliclazide treatment in Chinese newly diagnosed T2DM patients.Peripheral monocytes are decreased in non-abdominal obesity group and increased in abdominal obesity group after gliclazide treatment.

OBJECTIVETo evaluate the necessity of splenectomy in radical resection of gastric cancer.

METHODSTwelve studies comparing outcomes after radical resection of gastric cancer with or without splenectomy were identified. Both fixed effect model and random effect model were used.

RESULTSThere were 2628 patients in total. There were significant differences in complications between splenectomy group and spleen-preserving group(OR=1.91, 95% CI:1.28-2.87, P<0.05), while no significant difference in 5-year survival rate was noticed(HR=0.90, 95% CI:0.73-1.11, P>0.05).

CONCLUSIONRadical resection of gastric cancer combined with splenectomy is not associated with improved survival but increased postoperative complications.

The aim of study was to investigate the importance of chromosome aberration in differential diagnosis of eosinophilia and the chromosomal aberrations involved in patients with clonal eosinophilia. 65 cases of eosinophilia were collected and chromosome specimens of bone marrow cells were prepared by 24-hour culture, and G-banding technique was used for karyotyping. The results showed that out of 65 cases, chromosome 16 inversion was detected in 9 patients suspected as M(4Eo), and among the other 56 cases, 5 were detected with chromosomal aberrations (8.9%). Combining clinical, hematological and cytogenetical data, the 5 patients were diagnosed as acute myeloid leukemia with eosinophilia, chronic eosinophilic leukemia, 8p11 myeloproliferative syndrome, chronic myeloid leukemia in acute phase and acute myeloid leukemia-M(4Eo) respectively. The detected chromosomal aberrations were +14, t (5; 12) (q31; p13), t (8; 9) (p11; q32), t (9; 22) (q34; q11) and inv (16) (p13 q22). In conclusion, cytogenetical detection is very important in differential diagnosis of clonal eosinophilic disorders and chronic eosinophilic leukemia, which is suggested to be done routinely in clinic.

OBJECTIVETo observe and compare the medium-long-term efficacy of Kurokawa's and modified Kurokawa's double door laminoplasty for the treatment of cervical disorders.

METHODSA retrospective analysis was performed to compare the outcomes and complications between two kinds of operations on 172 cases from January 2002 to December 2010, including 106 cases of cervical spondylotic myelopathy, 52 cases of cervical stenosis, 21 cases of cervical ossification of the posterior longitudinal ligament. Patients were divided into two groups according to two surgical methods: traditional group, including 51 male and 18 female patients, with mean age of (56 ± 18) years (35-76 years); modified group, including 75 male and 28 female patients, with mean age of (58 ± 20)years (35-80 years). The two groups were comparable and compared according to different data using t test, χ(2) test and rank sum test.

RESULTSAll patients were followed up continuously for (52 ± 33)months, 123 patients were followed up ≥ 2 years, 71 patients ≥ 5 years. All patients' Japanese Orthopaedic Association (JOA) score improved significantly at the latest follow-up(t = 3.420, P < 0.01); no significant difference between the patients' JOA score improvement rate of two groups. The postoperative incidence rate of axial symptoms in patients of modified group (3.9%) was significantly lower than the traditional group (14.5%) (χ(2) = 7.548, P < 0.05), and cervical intervertebral activity decreased in the modified group was better than the traditional group in the first 3 months postoperatively (27% ± 6% vs. 19% ± 4%,Z = 6.34, P < 0.05), but during the medium-long-term follow-up, no significant difference in the cervical intervertebral activity decreased between two groups.

CONCLUSIONSMedium-long-term efficacy of Kurokawa's and modified Kurokawa's double door laminoplasty is satisfied and reliable. Avoiding damaging of semispinalis cervicis insertion in spinous process of C2, the modified operation method can protect the extensor group of the neck muscle and reduce the incidence of postoperative axial symptoms better.

OBJECTIVETo construct eukaryotic expression vectors by using the pSilencer3. 1-H1 neo vector for inhibiting human survivin gene by RNA interference, and to detect the effect of the silenced survivin gene on PC-3 cells.

METHODSThree target gene segments were synthesized and cloned into the pSilencer3. 1-H1 neo vector respectively to construct three recombinant eukaryotic expression vectors: pSilencer3. 1-SVV1, pSilencer3. 1-SVV2 and pSilencer3. 1-SVV3, which were identified by enzyme digestion analysis and DNA sequencing. Then the PC-3 cells were transfected with the recombinant vectors and the interference effect detected by RT-PCR, Western blot and immunohistochemical staining. The apoptosis index of the PC-3 cells was detected by flow cytometry and their proliferation detected by MTT method.

RESULTSEnzyme digestion analysis and DNA sequencing showed that three target segments were cloned into pSilencer3. 1-H1-neo vectors. The results of RT-PCR, Western blot and immunohistochemical staining indicated that pSilencer3. 1-SVV2 and pSilencer3. 1-SVV3 vectors could knock down the transcription and expression of survivin gene. After transfected with pSilencer3. 1-SVV2 and pSilencer3. 1-SVV3 vectors, the apoptosis index of the PC-3 cells was increased by 10% - 15% and their growth obviously slowly down.

CONCLUSIONThe transcription and expression of survivin gene were inhibited effectively by the recombinant eukaryotic expression vectors (pSilencer3. 1-SVV2 and pSilencer3. 1-SVV3) in the prostate cancer cell line PC-3. After transfected with pSilencer3. 1-SVV2 and pSilencer3. 1-SVV3 vectors, the apoptosis index of the PC-3 cells was increased and their growth inhibited.

It is reported, in the process of diabetic nephropathy (DN), inflammatory-related p38 mitogen-activated protein kinase (MAPK) signaling pathway has a close relationship with renal injury. On the one hand,many factors in the upstream including hyperglycemia, abnormal hemodynamics, oxidative stress, and pro-inflammatory cytokines could activate p38MAPK signaling pathway. On the other hand,the activated p38MAPK signaling pathway could lead to renal damage via activating inflammatory cells, inducing the expression of inflammatory mediators, and intervening cytokines production. CHM could intervene p38MAPK signaling pathway through multi-ways, including inhibiting inflammatory cytokines expression, regulating phosphorylated p38MAPK (p-p38MAPK) expression, and reducing fibrogenic factors expression.
