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.

Repeat cervical cytologic testing,human papillomavirus(HPV)testing and immediate colposcopy are currently the most general managements in women with atypical squamous cells of undetermined significance(ASCUS)result.However,the efficacy of these three methods is hampered by strong subjectivity,high false negative and positive rates.With the development of the aetiology of cervical cancer,there is good evidence that biomarkers for persistent HPV infection,HPV integration,instability of host genes and malignancy triage ASCUS more objectively and efficiently.The three-dimensional multiparameter biomarker-based detection may be the predominant method for the triage of women with abnormal cervical cancer screening result.

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.
