To explore the effect of quercetin on the proliferation and apoptosis of HeLa cells, HeLa cells were incubated with quercetin at different concentrations. Cell viability was evaluated by MTT assay, cell apoptosis was detected by Annexin-V/PI double labeled cytometry and DNA ladder assay. Cell cycle was flow cytometrically determined and the morphological changes of the cells were observed under a fluorescence microscope after Hoechst 33258 staining and the apoptosis-related proteins in the HeLa cells were assessed by Western blotting. The results showed that quercetin significantly inhibited the growth of HeLa cells and induced obvious apoptosis in vitro in a time- and dose-dependent manner. Moreover, quercetin induced apoptosis of HeLa cells in cell cycle-dependent manner because quercetin could induce arrest of HeLa cells at G0/G1 phase. Quercetin treatment down-regulated the expression of the PI3K and p-Akt. In addition, quercetin could down-regulate expression of bcl-2, up-regulate Bax, but exerted no effect on the overall expression of Akt. We are led to conclude that quercetin induces apoptosis via PI3k/Akt pathways, and quercetin has potential to be used as an anti-tumor agent against human cervix cancer.

Objective To observe the serum adiponectin, leptin level, and adiponectin/leptin ratio (A/L ratio) in elderly male patients with normal BMI and visceral adipose deposit but without metabolic syndrome. Methods A total of 109 elderly males (≥60 years old) were enrolled whose BMI were all less than 25 kg m and without metabolic syndrome. They were divided into non visceral adipose deposit group (n = 67) and visceral adipose deposit group (n = 42 ). Serum levels of adiponectin and leptin were measured by radiological immunological assay (RIA) and the A/L ratio was calculated. Visceral adipose deposit was defined as visceral adipose area more than 100 cm2.Metabolic syndrome diagnosis was according to the definition provided by China Diabetes Society (CDS) in 2004. Results (1)The visceral adipose area [(135.56±31.72)cm2 vs. (68. 65±22.64)cm2 , P< 0. 001] and BMI [(22.94 ± 1.35 ) kg/m2 vs. ( 21.38 ± 2.55 ) kg/m2 , P < 0.001] were significantly higher in visceral adipose deposit group than in non visceral adipose deposit group. The A/L ratio was significantly lower in visceral adipose deposit group than in non visceral adipose deposit group ( 2. 17 ± 1.77 vs. 4.54 ± 7.00, P = 0. 034 ) while there was no difference in serum adiponectin or leptin level between those two groups. (2)The A/L ratio was negatively correlated with BMI (r=-0.552, P<0.001), waist circumstances (r=-0.390, P<0.001) and abdominal visceral fat area (r=-0.341, P<0. 001 ). Conclusions The A/L ratio decreases in elderly men with normal BMI and visceral adipose deposit. A/L ratio could be useful in scanning those patients with visceral adipose deposit whose BMI is normal among elderly men.

Objective To assess cognitive impairment of patients with idiopathic Parkinson's disease(PD)of different clinical subgroups. Methods The cluster analysis approach was used to classify PD patients on the basis of their clinical features, and then compare their cognitive function according their Montreal Cognitive Assessment (MoCA)score. Results One-hundred and six patients were divided into 5 groups by means of cluster analysis:A. young-onset(n = 35), B. rapid disease progression(n = 6); C. tremor dominant(n = 36), D. haplo-non-tremor dominant(n =18),E. non-tremor dominant with depression(n = 11). The MoCA score and proportion of abnormal scores differed among the 5 groups significantly,especially between the subgroup E(19.00 ±5.47)and the subgroup A(23. 66 ± 3.51)(P < 0. 05), the former was more seriously impaired in clock drawing task(1.73 ± 1. 01 vs.2. 66 ±0. 59 ,t = -2. 904,P =0. 013), alertness(0. 55 ±0. 52 vs. 0. 91 ±0. 28 ,t = -2. 241 ,P =0. 045),semantic fluency(0. 64 ±0. 51 vs. 0. 97 ±0. 17 ,t = -3. 429,P =0. 001)and orientation domains than the latter(4. 91 ± 1.38 vs. 5.80±0.47,t = -3.321,P =0.020). Conclusions The cognitive impairment in PD patients are common as well as heterogeneous.

Objective To investigate the risk factors of Parkinson's disease(PD)with mild cognitive impairment and mode of cerebral glucose metabolism. Methods One hundred and one non-dementia PD patients were assessed with Montreal Cognitive Assessment(MoCA)and divided into the PD with mild cognitive impairment (PD-MCI)group and the PD non-cognitive impairment(PD-NC)group. The demographic details, clinical features,Unified Pakinson's Disease Rating Scale(UPDRS), Hohen-Yahr rank and Hamilton Depression Scale(HAMD)were compared between the two groups. Patients in Hohen-Yahr stage 1 underwent positron emission tomography(PET)with 18F-fluorodeoxyglucose(18F-FDG)to show glucose metabolism. Results Seventy-seven(74. 3%)PD patients had mild cognitive impairment PD-MCI group had higher score in UPDRS 1st(mentation ,behavior and mood),2nd (activity of daily living)and 3rd(motor examination)subscale(2.48 ± 1.51,10. 71 ± 4. 88,22.31 ± 12.70)than PD-NC group(1.65 ± 1.29,8.15 ±2. 20,15.92 ±7.56,P <0.05)respectively. The FDG metabolism ratio of frontal cortex,parietal cortex and occipital cortex decreased more significantly in PD-MCI than in PD-NC(P < 0.05).Conclusions The risk factors of mild cognitive impairment in PD include moter dysfunction, clinical stage and depression. The metabolic dysfunction of cortex may be the mechanism of mild cognitive impairment in PD.
