Objective To explore the improvement of cognitive impairment in patients with mild and moderate vascular cognitive impairment( VCI) treated with cerebralcare granule ( CG) and basic treat-ment.Methods From October in 2014 to December in 2016 year,143 cases of VCI patients were admitted from six hospitals in some areas of Hebei Province as the research objects,and divided into CG treatment group (experimental group,n=98) and conventional treatment group (control group,n=66).Three months and six months after treatment,the score of mental state examination ( MMSE) ,the Montreal cognitive assess-ment scale ( MoCA) and the daily living capacity scale( ADL) of the two groups were compared after 3 and 6 moths of treatment.Results ①The total score of MMSE in the experimental group was higher than that of the control group for six months after treatment, and the difference was statistically significant ( ( 23. 76 ± 4.02) vs (21.52±5.13),P<0.05).②Six months after treatment,the total score of MoCA ((21.06±4.66) vs (18.32±5.20)) and visual spatial/executive function((3.05±1.37) vs (2.42±1.66)),calculation force ((2.24±0.84) vs (1.83±1.05)) and orientation ability((5.20±1.12) vs (4.06±1.35)) scores in the ex-perimental group were significantly higher than those in the control group (P<0.05) .③Six months after treat-ment,the ADL score in the experimental group was lower than that before treatment,and the difference was statistically significant((24.96±8.74) vs (29.20±11.55),P<0.05);while there was no significant difference in the ADL score between the experimental group and the control group after 6 months (P>0.05).Conclusion CG can improve cognitive function in mild to moderate VCI patients,mainly in visual space/execution func-tion,calculation ability and orientation ability,and with the extension of treatment time,the curative effect is more obvious.

Objective To investigate the clinical value of serum lipoprotein associated phospholipase A 2 (Lp-PLA2)as a biomarker for benign prostatic hyperplasia(BPH).Methods A total of 65 serum samples of BPH patients were selected as BPH group,64 serum samples of healthy male as control group.The serum lev-el of Lp-PLA2,total prostate specific antigen(tPSA)and free prostate specific antigen(fPSA)in both groups were detected,and the specificity and sensitivity of Lp-PLA2,F/T ratio and combine both were analyzed by ROC curve.Results The serum level of Lp-PLA2,tPSA and fPSA in BPH group were significantly higher than those in control group,the different were significant(P<0.05).ROC curve analyze shown that the area under the curve(AUC)of Lp-PLA2 was 0.763,95% confidence interval(CI)was 0.680-0.833;AUC of F/T ratio was 0.715,95% CI 0.633 -0.795;AUC of Lp-PLA2 combined with F/T ratio was 0.832,95% CI 0.756-0.892.Conclusion The serum level of Lp-PLA2 could be used as a potential diagnostic marker for BPH,and the diagnostic value of Lp-PLA2 combined with F/T ratio was better than ther single indicator. Key words:benign prostatic hyperplasia; lipoprotein associated phospholipase A 2; total prostate spe-cific antigen; free prostate specific antigen; F/T ratio

[Objective] To investigate the variation of Q promoter (Qp) in nasopharyngeal carcinoma (NPC) cells, and to compare the existing two mutant sites [62 225 site(g→a)and 62 422 site (g→c) ] Qp in NPC cells with the Qp in B95.8 cell line in the functional and biological difference. [Methods] The Qp sequence was amplified in the samples from 29 cases of paraffin-embedded tissues of NPC suffers and 14 cases of peripheral blood of healthy adults by polymerase chain reaction (PCR) method (totally 43 cases). The point mutations on specified sites were analyzed and statistically compared from sequencing results. The sequences of variant and prototype Qp were amplified by PCR and cloned into luciferase reporter vector (pGL3-basic), then transfected into HaCat cells respectively. The transcriptional activity was compared between variant and prototype Qp using luciferase reporter system. The DNA binding affinity of mutant and prototype Qp to Sp1 was compared through chromatin immunoprecipitation (CHIP) method since mutation of nt 62 225 located in a Spl binding site. [Results] The mutation rate of Qp was significantly higher in NPC compared with healthy controls (P=0.039 5, <0.05), which suggested the variant Qp was closely associated with NPC. The transcription of the luciferase gene promoted by variant Qp was significant more than that of prototype Qp in transient transfection assay (2.5:1, P<0.05). The binding affinity of variant Qp to Sp1 was about 1.52 times higher than that of prototype Qp as determined by quantitative ChIP assay. [Conclusions] The transcriptional activity was enhanced in variant Qp in NPC cells compared with prototype, which possibly through the higher binding affinity to Sp1. We suggest that the mutated Qp may play an important role during the EBV infection and transformation of nasopharyngeal epithelium.
