Objective To evaluate the effect of alcoholism history on the elderly patients’early cognitive function after lower abdominal or limbs surgery under general anesthesia through controlled clinical trials.Methods Sixty male patients aged 65-80 years of ASA grade Ⅰ or Ⅱ were selected un-dergoing lower abdominal or limbs surgery,30 cases with alcoholism history as alcohol group(group A),30 cases without alcoholism experience as control group (group C).All patients were anesthe-tized intravenously.The general data before and during operation,and the postoperative complications were recorded.The mini mental state examination(MMSE)was performed to assess the cognitive function 1d before and 1,7 d after surgery,then post-operative cognitive dysfunction(POCD)was compared between the two groups through analysis of the MMSE score.Results The MMSE score of 1,7 d after surgery in two groups was significantly lower than that of the preoperative(P < 0.05 ). Compared with the score 1 d after surgery,the score of 7 d post-operation was significantly higher in group A (P <0.05).The postoperative score in group A were significantly lower than that in group C 1,7 d after surgery (P <0.05).The incidence of POCD in group A were higher than that in group C 1,7 d after surgery (P <0.05 ).Conclusion Alcoholism history can increase the incidence of early cognitive dysfunction in elderly patients after general anesthesia.

Objective To explore the effects of adipose tissue-derived stem cells (ADSCs) on the proliferation and invasion of pancreatic cancer cell lines in vitro.Methods ADSCs were isolated and co-cultured with pancreatic cancer cells.The proliferation and invasion of pancreatic cancer cells was tested by CCK-8 test kit.Stromal cell derived factor (SDF-1),vascular endothelial growth factor(VEGF),matrix metalloproteinase(MMP-9)and transforming growth factor-β (TGF-β1)in the culture medium were assayed by ELISA.The expression of cytokines in pancreatic cancer cells and ADSCs were detected by qRT-PCR.CCK-8 test kit was used to measure the AMD3100 regulation for the co-culture of ADSCs and pancreatic cancer cells.Results ADSCs can promote the proliferation and invasion of pancreatic cancer cells (all P ＜0.05); more SDF-1,VEGF,MMP-9 and less TGF-β1 was secreted by ADSCs than by pancreatic cancer cells(SDF-1:1100±100 vs.0 vs.0,F=389.134,P＜0.01;VEGF:140±4 vs.99±5 vs.93 ±4,F=174.102,P ＜0.05;MMP-9:61.8 ±4.2 vs.43.5 ±2.8 vs.54.5 ±3.0,F=76.279,P＜0.05;TGF-β1:20.6 ±3.0 vs.35.6 ±2.6 vs.41.3 ±5.5,F =79.338,P ＜0.05).ADSCs promote the expression of VEGF and MMP-9 in pancreatic cancer cells(VEGF:63.7 ±5.9 vs.50.6 ±4.1,t =7.536,P＜0.05; MMP-9:mRNA(55.8±3.6 vs.42.7 ±3.1,t =8.279,P＜0.05).AMD3100 significantly downregulates these growth-promoting effects of ADSCs on pancreatic cancer cells(SW1990:1.539 ±0.140 vs.1.361±0.066,t=2.835,P＜0.05;PANC-1:1.376±0.100 vs.1.281±0.031,t=2.860,P＜0.05).Conclusions ADSCs promote the proliferation and invasion of pancreatic cancer cells.

Cerebral smal vessel disease (CSVD) can be divided into sporadic and hereditary CSVD. The exact pathogenesis of sporadic CSVD is unknow n. Genetic factors may also play an important role, except for environmental and vascular risk factors. As a complicated disease, sporadic CSVD has the characteristics of multigenetic susceptibility. Therefore, investigating the related genetic factors may contribute to understanding the pathogenesis of sporadic CSVD. This article review s the advances in research on the genetics of sporadic CSVD.

Objective To discuss the image characteristics of enlarged prostatic utricle in children.Methods 13 children with enlarged prostatic utricle were retrospectively analyzed,6 of whom checked by voiding cystic urethrography (VCUG),5 of whom by MRI,2 of whom by both VCUG and MRI.Results 8 cases with VCUG showed round-like or long circle utricle filled with contrast media located in the rear posterior urethra.Among them,3 cases showed the tubiform between utricle and posterior urethra.The other 5 cases displayed overlap between utricle and urethra,and there was no tubiform between utricle and posterior urethra.7 cases with MRI showed oblong cyst at the right rear middle of the bladder that showed low signal with T1 weighted image and high signal with T2 weighted image,crossing the center of prostate gland.Among them,5 cases showed the communication between oblong cyst and posterior urethra.Also,among them,5 cases were associated with the orchitis,epididymis phlogistic,scrotal phlogistic,and 1 case showed the right renal agenesis.Conclusion The VCUG and MRI are helpful to check enlarged prostatic utricle in children.They have different advantages in different aspect.

Objective To investigate the status of self-care ability and cognition among disabled elderly,and to analyze the relationship between self-care ability and cognition,then analyze their influencing factors.Methods A total of 813 disabled elderly accepted long-term care at community or facility were recruited by stratified sampling method and investigated by socio-demographic questionnaire,activities of daily living and short portable mental status questionnaire.Results The total scores of self-care ability of the long-term care disabled was 32.01±11.59,and the total points of cognition was 3.77±3.24.Disabled elderly with severe disorders of self-care ability had a higher obstacle rate in every cognition ability than those with mild disabilities (P＜0.001).There were differences in orientation and memory function with different persistent disabled time (x2 =11.875,14.758,P＜0.01).Disabled elderly with cognition obstacles have a higher obstacle rate in every self-care aspect than those with normal cognition (P＜0.01).The multiple regression analysis showed that the educational level (β=-0.067),arital status (β=-0.071),disabled persistence time (β=0.121),orientation ability (β=0.403),the amount of cognition obstacles (β=0.443) were the influence factors of Basic Activities of Daily Living(BADL) among disabled elderly ; and disabled persistence time (β=0.116),orientation ability (β=0.417),recalled ability (β=0.275),memorial ability (β=0.189),calculative ability (β=0.257),the amount of cognition obstacles (β=0.358) were the important factors influence Instrumental Activities of Daily Living(IADL).Conclusion The self-care ability and cognition of the long-term care elderly were declining sharply,and influencing each other.It is advisable to offer them direct long-term care service combined with the laws and characteristics of cognition and self-care ability.

Semen Ziziphi spinosae ( SZS) , as a commonly used traditional Chinese medicine in clinic for insomnia therapy, is rich in pharmacological active ingredients such as saponins, flavonoids, alkaloids, oil and the other chemical compounds. The recent stud-ies indicated that some active ingredients in SZS exhibited a variety of activities including sedative hypnotics, antianxiety and anti-de-pression by regulating particular neurotransmitters such as 5-hydroxytryptamine (5-HT), gamma-amino butyric acid (GABA), norepi-nephrine, dopamine and glutamate. In accordance with the previous studies on pharmacological activities of SZS, this paper summa-rized and reviewed the applications of SZS in the treatment of central nervous system diseases, myocardial diseases and hepatic disea-ses, which might provide solid evidence for the application development of SZS.
