Chinese Journal of Diabetes 2017;25(1):58-61
Objective To investigate the effects of Metformin on serum proprotein convertase subtilisin/kexin type 9(PCSK9)level in patients with type 2 diabetes(T2DM). Methods 48 healthy people with normal glucose tolerance were selected as the controls (NGT group). 93 newly diagnosed T2DM were randomized to Metformin treated group (Met,n= 47 )and Glipizide treated group (Gli,n=46).Serum PCSK9 was measured by ELISA in all participants. After treatment,the changes of serum PCSK9 were observed in Met group and Gli group. Results Serum PCSK9 levels in Met group and Gli group were higher than NGT group(P<0. 01). PCSK9 level was positively correlated with FPG,HbA1 c, HOMA-IR,FIns,TC,LDL-C,TG,hsC-RP,TNF-αand BMI (r= 0. 578,0. 638,0. 556,0. 610,0. 578, 0. 592,0. 589,0. 638,0. 561,0. 552;P<0. 05 or P<0. 01),and negatively correlated with HDL-C(r=-0. 614,P<0. 01). The levels of PCSK9 significantly decreased after treatment with Metformin(P<0. 05). PCSK9 levels had no significant differences before and after treatment with Glipizide. Multiple regression analysis showed that TNF-αand HOMA-IR were independent related factors of PCSK9. Conclusion T2DM patients have high levels of serum PCSK9 which can be decreased by Metformin.

Objective To investigate the changes of serum stromal cell‐derived factor‐1α (SDF‐1α) in patients with diabetic peripheral neuropathy (DPN) and the influence of mouse never growth factor (MNGF) on the levels of serum SDF‐1α. Methods 180 patients with type 2 diabetes (T2DM ) were divided into T2DM with DPN (DPN group ,n=92) and T2DM without DPN (T2DM group ,n=88). 90 healthy people were select as normal control (NC group). DPN group was divided into 47 cases of MNGF treatment (A) subgroup and 45 cases of basic treatment (B) subgroup. The levels of serum SDF‐1αwere measured using ELISA method. The relationships between the levels of serum SDF‐1αand SOD ,TGF‐β1 , hsC‐RP ,and GAP‐43 were analyzed. After treatment ,the levels of serum SDF‐1α in A and B subgroups were compared. Results Compared with NC group [(0.91 ± 0.37)μg/L] ,the levels of serum SDF‐1αin T2DM and DPN group were higher [(2.58 ± 0.58) μg/L and(1.71 ± 0.43)μg/L ,respectively ,P<0.05 or P<0.01]. The levels of SDF‐1αwere positively correlated with FPG ,HbA1 c ,TGF‐β1 and hsC‐RP ,and negatively correlated with SOD in T2DM group. The levels of SDF‐1αwere positively correlated with TG and TGF‐β1 ,and negatively correlated with course of disease ,FPG ,HbA1 c ,SOD ,hsC‐RP ,GAP‐43 , MMCV ,PMCV ,MSCV and PSCV in DPN group. SDF‐1α levels were significantly increased after treatment with MNGF in subgroup A [(1.75 ± 0.39) vs (2.09 ± 0.45)μg/L ,P<0.05]. There were no significant difference of SDF‐1αlevels after treatment in subgroup B [(1.67 ± 0.48) vs (1.71 ± 0.51)μg/L , P>0.05] .Multiple stepwise regression analysis showed that HbA1c ,hsC‐RP and PSCV were the independent factors related with the levels of SDF‐1αin DPN patients. Conclusion The levels of serum SDF‐1αin DPN patients are lower than in T2DM patients without DPN. MNGF may increase the level of serum SDF‐1α.

Chinese Journal of Tissue Engineering Research 2009;13(27):5252-5256
BACKGROUND: Studies have shown that after bone marrow stem cell transplantation, there are juvenile cells with the episode of myocardial cells around the infarct areas, which was recognized as deriving from bone marrow stem cells.OBJECTIVE: To explore the homing situation of bone marrow stem cells by autologous mobilization around the infarct areas aftar myocardial infarction.DESIGN, TIME AND SETTING: The cytological in vitro study was performed at the China-Japan Clinical Pathology Center, Daliar Medical University from February 2005 to April 2006.MATERIALS: A total of 30 myocardial samples from the autopsy at the Department of Pathology and Forensic Medicine, Dalian Medical University between 2000 and 2005. Fifteen normal samples dyed from the mechanical injuries or craniocerebral injury,without abnormity following autopsy. Fifteen samples in the myocardial infarction group suffered from coronary atherosclerosis and coronary tube stenosis, and died within 10 days after myocardial infarction.METHODS: The autopsy was performed within 48 hours after the death and the tissues were obtained from antedor wall, lateral wall and posterior wall of the left ventricle, and made into tissue sections. We checked the expression of CD34, CD133 and transforming growth factor-β, in the normal area, infarct area and around the infarct area by immunohistochemistry.MAIN OUTCOME MEASURES: The expression of CD34, CD133 and transforming growth factor-β in different areas and the relationship between them.RESULTS: The positive expression of CD34 in infarct area was significantly stronger than that around the infarct area and in normal area (P < 0.01). The positive expression of transforming growth factor-β in infarct area was significantly stronger than that around the infarct area (P < 0.01), and the expression of transforming growth factor-β showed negative reactJon in normal area. The expression of CD34, CD133 and transforming growth factor-β, in infarct areas and around the infarct area was closely related (P < 0.01).CONCLUSION: There are the homing of bone marrow hemopoietic stem cells in infarct area and around the infarct ares after myocardial infarction. The increase in transforming growth factor-β in infarct area provides the possibility for the differentiation of the homing stem cells, the following angiogenesis and the regeneration of cardiomyocytes.

Objective To investigate the clinical and pdysomnographic characteristics and related factors of obstructive sleep apnea hypopnea syndrome (OSAHS) in elderly patients. Methods The 163 elderly patients with OSAHS confirmed by polysomnography were classified into obesity group and non-obesity group according to body mass index (BMI). All cases were grouped into mild,moderate and severe groups according to the apnea hypopnea index (AHI) and night SaO2. The 190non-elderly OSAHS patients were as control group at the same time. The clinical and polysomnographic characteristics were recorded and analyzed. Results (1)The proportion of obesity in OSAHS patients was 79. 1%, there was significant difference between the elderly-obesity group and non-elderly-obesity group (70.3% vs. 83.6%, P<0.05). (2)The proportions of moderate and severe OSAHS patients were lower in elderly group than in non-elderly group. There were significant differences in AHI, the lowest arterial O2 saturation (LSaO2) and % TRT SaO2 <90% between the two groups (all P<0.05). (3)The sleep architecture disturbance was significantly severer in elderly group than in non-elderly group. The percentages of non-rapid eye movementsleep (NREM sleep)stage Ⅲ-Ⅳ sleep were significantly decreased, and the arousal was significantly increased. (4) The syndrome of OSAHS in elderly group was untypical and the clinical complication was increased.Conclusions The elderly OSAHS patients are less severe than non-elderly group, but the elderly patients have worse sleep architecture disturbance and more complications such as hypertension and other cardiovascular diseases.
