To compare the effect of insulin glargine combined with nateglinide and continuous subcutaneous insulin infusion(CSII) during intraoperative period in type 2 diabetic patients with fracture. Both of the managements made blood glucose under control [fasting blood glucose(6.89±1.96)vs(6.75±2.33)mmol/L] in similar period [(3.6±1.6)vs(2.9±1.2) d,both P>0.05]. The mean blood glucose was lower in patients treated by CSII than that of the other group.

Objective To investigate the therapeutic and adverse effects of short-term continuous subcutaneous insulin infusion (CSII) in patients with newly-diagnosed type 2 diabetes mellitus. Methods By way of follow-up and retrospective study, 256 patients with newly-diagnosed type 2 diabetes mellitus receiving two weeks of CSII therapy were analyzed in our diabetes center. The parameters, such as blood glucose level after two-week CSII therapy, time needed to control hyperglycemia, insulin dosage and the rate of hypoglycemic episodes were observed and recorded. Results The optimal glycemic control rates after 3 days, 7 days, 2 weeks were 46.7%, 78.4%, 92.2% respectively. The remission rates of patients who maintained optimal glycemic control at the third, sixth, twelfth, twenty-fourth and thirty-sixth months and more than 48 months after withdrawal of insulin were 75%, 64.8%, 53.5%, 30.9%, 10.2% and 0%, respectively. In patients with a period of remission over 3 months,the daily total insulin requirement on the day of withdrawal of CSII was less than that in patients with remission less than 3 months (P＜0.01). The duration of remission was negatively correlated to daily insulin requirement on the day of CSII withdrawal(r=-0.63, P＜0.01). Conclusion Patients with newly-diagnosed type 2 diabetes mellitus can quickly achieve optimal glycemic control by CSII. CSII may decrease glucotoxicity to pancreatic β cells and delay the deterioration of β-cell function .

Objective To investigate the expression of BAMBI in pancreatic carcinoma tissue and its clinical value.Methods Expression of BAMBI was detected by immunohistochemistry in 69 cases of pancreatic cancer and 15 normal pancreatic samples.The survival and its association with clinicopathologic parameters were analyzed.Results The expression of BAMBI in the cancer tissue was much higher than that in the normal tissues (56.5％ vs 16.7％,P ＜0.01).The expression of BAMBI was not associated with age,sex and tumor size,differentiation,but expression of BAMBI in patient with lymph node metastasis was higher than that in patient without lymph node metastasis (67.4％ vs 38.5％,P =0.019),the expression of BAMBI in TNM stage Ⅲ was higher than that in stage Ⅰ + Ⅱ (75.0％ vs 31.0％,P =0.001).The median survival of BAMBI-positive group (6 months) was lower than that of BAMBI-negative group (10 months).Conclusions BAMBI is over-expressed in pancreatic carcinoma,and its expression is associated with lymph node metastasis,TNM staging,differentiation and prognosis.

Objective To observe the effect of sinomenine (SIN) on the expression of cyclooxygenase (COX2),alpha-7 nicotinic acetylcholine receptor(α7nAChR) and adenosine receptor(A2A) in A549 cells,and to explore the relative mechanism for cell proliferation.Methods The effect of SIN and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) on the proliferation of A549 cells was determined by methyl thiazolyl tetrazolium (MTT) assay.The effect of SIN and NNK on the migration of A549 cells was detected by cell wound scratch assay.The effect of SIN and NNK on COX2 expression in A549 cells was determined by Western blotting method.The effect of SIN and NNK on the expression of α7nAChR and A2A mRNA and protein was evaluated by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting method.Results NNK increased the proliferation and migration of A549 cells,while SIN inhibited the proliferation and migration of A549 cells.COX2 expression level was increased in NNK group but was decreased in SIN group.The expression levels of α7nAChR and A2A were up-regulated in NNK group but were down-regulated in SIN group.Conclusion SIN plays a role in inhibiting the proliferation and migration of A549 cells by suppressing COX2 expression.SIN has an inhibitory effect on the expression of α7nAChR and A2A.

Objective To evaluate the therapeutic effects and safety of amitrine bismesylate in patients with mild vascular dementia.Methods An open multicenter self-controlled trial was carried out with 128 mild vascular dementia patients clinically diagnosed.Patients were treated with amitrine bismesylate in a dose of 2 tablets per day for 12 weeks.The neuro-psychologieal scale of MMSE,ADAS-cog,CDR, ADL were used to evaluate patients′cognitive condition before therapy and 6,12 weeks after treatment.The adverse effects,such as nausea and vertigo and so on,were monitored at the same time to evaluate the safety of this drug.Results After 3 months of treatment,the MMSE score(16.98 before therapy and 17.97 after treatment,P

AIM: To screen TIGR/myocilin gene (MYOC) mutation in high myopic Chinese children with family history.METHODS: Gene sequencing was performed in exon 3 of the TIGR gene in high myopic Chinese Children. The coding sequence of TIGR exon 3 was screened by capillary electrophoresis sequencing. The sequence alterations were analyzed by bioinformatics.RESULTS: TIGR gene mutation was not found in high myopic patients and normal controls group.CONCLUSION: No identified gene mutation is found in TIGR gene in high myopic Chinese children.

OBJECTIVETo investigate the correction of secondary nasal deformity of cleft lip with autogenous costal cartilage framework.

METHODS237 cases with secondary nasal deformity of unilateral cleft lip were treated. The rib cartilage was harvested through a mini-invasive incision, and was fabricated as a C-shaped framework, as well as some cartilage fragments. Through transcolumella incision, the C-shaped framework was implanted to support the depressed alar and the cartilage fragments were used to augment the nasal base.

RESULTSSatisfactory cosmetic and functional results were achieved in all the patients with primary healing. 93 patients were followed up one year after operation with good cosmetic results.

CONCLUSIONSAutogenous costal cartilage framework can be used for the correction of secondary nasal deformity of cleft lip with satisfactory results.

Objective To investigate the changes of CD4+ CD25+ regulatory T lymphocyte (Treg) and expressions of folkhead helix transcription factor 3 (FoxP3) in intestinal mucosa in human immunodeficiency virus (HIV) infected patients. Methods Twenty-one HIV infected patients and 17 control subjects without HIV infection were included in this study. The expression of FoxP3, which was considered as a specific marker of CD4+ CD25 + Treg, was detected in intestinal mucosa specimens from HIV infected patients by immunohistochemistry. Meanwhile, the in situ expression of CD4+ T lymphocyte was also determined by immunohistochemistry. The data were analyzed by t test. Results The positive labeling index of CD4+ T lymphocyte in intestinal mucosa was significantly lower in HIV infected patients compared to the controls (11. 56%±4. 44% vs 43. 49% ±8. 90% ,t=-11. 86,P<0. 01). The positive labeling index of FoxP3 in intestinal mucosa was also significantly lower in HIV infected patients compared to the controls (0.46% ± 0.20% vs 1. 18% ± 0. 44% ,t= - 5. 98,P<0.01). Conclusion The depletion of CD4+ CD25+ Treg is accompanied with the depletion of CD4 + T lymphocyte and the reduction of FoxP3 expression in intestinal mucosa of HIV infected patients.

OBJECTIVETo observe the variations of intracellular localization and expression of importin 8 (IPO8) during osteoblast differentiation.

METHODSAlizarin red staining, immunocytochemistry and real-time PCR were employed to examine the changes in the intracellular localization and expression of IPO8 mRNA during induced osteogenic differentiation of human osteoblast-like SaOS-2 cells.

RESULTSNumerous red mineralized nodules were observed on day 10 in the induced cells with alizarin red staining. Immunocytochemical staining showed that IPO8 immunoreactivity was the strongest in the perinuclear cytoplasm of the cells. On day 3 of osteoblast differentiation, IPO8 immunoreactivity in the cell nuclei became stronger. On day 7, IPO8 was located mainly in the nuclei, and on day 10 the cells were osteocyte-like and IPO8 was distributed in the cytoplasm. Real-time PCR showed a significantly increased expression of OPN mRNA during osteoblast differentiation, and the expression level of IPO8 mRNA was the highest on day 3 and declined on days 7 and 10.

CONCLUSIONThe intracellular localization and expression level of IPO8 undergo significant changes during osteogenesis, indicating its role in regulating osteoblast differentiation.
