1.A survey of the consultative status of patients with Alzheimer disease and the efficacy and safety of donepezil treatment
Chinese Journal of Geriatrics 2010;29(8):691-693
Objective To investigate the consultative status of patients with Alzheimer Disease (AD), and to evaluate the efficacy and safety of donepezil (Aricept) in the treatment of AD.Methods This survey was initiated by Chinese society of Geriatrics, and was sponsored by Eisai (China) Inc. It was conducted in 60 hospitals of 40 cities in China. The diagnosis of dementia was made according to ICD-10 and DSM-Ⅳ criteria. The cognition, behavior and ability of daily living of the patients were compared before and after 3-month treatment with donepezil. Results A total of 808 dementia patients were recruited. The main reasons for patients' seeing doctors included memory problem (n= 703, 87%), behavioral and psychological symptoms (n= 250, 31%), impairment of ability of daily living (n= 388, 48% ). The disease course was from 9 months to 16 months, and mean disease course was (13.0 ±0. 2) months. Patients mainly sought treatment from neurologist (74 % ),psychiatrist (6 % ) and geriatrics ( 19 %). They received dementia diagnosis at ( 14.4 ± 0.3) months after their dementia symptoms appeared. Treatment with donepezil for three months improved their cognition, ability of daily living and mental condtion (all P<0.05). The main adverse effects were nausea, vomiting etc. Conclusions In China, the percentage of people with dementia seeking treatment is low. Most people with dementia see doctors when they reach moderate and severe stages,which affects the efficacy of treatment and daily activity of the patients. Treatment with donepezil for 3 months is effective in improving cognition, behavior and activity of daily living.
2.The nervous system adverse effect induced by β-lactam antibiotics in patients on hemodialysis
Clinical Medicine of China 2009;25(7):739-741
Objective To discuss the reasonable utilization of β-lactam antibiotics in patients with renal failure on hemedialysis. Methods The clinical characteristics of patients with renal failure on hemodylysis,who de-veloped the adverse effect of nervous system and psychiatric symptom while being treated with β-lactam antibiotics,were retrospectively analyzed. Results The adverse effect of nervous system and psychiatric symptom showed dur-ing and after hemodialysis,including: mental confusion,hyperexcitabiliy,incoherent speech,lethargy and amyestasia in two cases. Physical examination did not show signs of cerebral focal injury in all cases. Computed tomography of brain in 7 patients did not show acute lesions. The symptoms completely disappeared after withdrawal of β-lactam antibiotics but bemodialysis or hemodiafiltration continued. Conclusion β-lactam antibiotics used in conventional dose could cause temporary adverse effect of nervous system in patients with renal failure on bemodialysis,which is related to prolongation of drug half life.

Objective To investigate relationship between insulin sensitivity and beta-cell function with body mass index (BMI) and age in patients with newly diagnosed type 2 diabetes mellitus (T2DM).Methods Totally, 304 patients with T2DM newly-diagnosed at admission to the first hospital affiliated to Nanjing Medical University, Jiangsu province, during 2006 to 2007 were recruited in the study. The patients were divided into three groups based on WHO criteria of obesity in Asia Pacific Region in 2003, 68 cases with normal weight ( 18. 5≤ BMI < 23.0), 69 in overweight (23.0 ≤ BMI < 25.0), and 167 in obesity (BMI≥25.0). Fasting serum glucose, glycesylated hemoglobin Alc (HbAlc) and lipids were measured for all the subjects, as well as oral glucose tolerance test (OGTr), C-peptide releasing tests and determination of serum insulin performed. Homeostasis model assessment of insulin resistance index (HOMA-IR), insulinogenic index (AI30/AG30) and modified beta-cell function index (MBCI) werecalculated to evaluate their insulin sensitivity and beta-cell function of the islets. All these parameters werecompared between the three groups and subgroups. Results HOMA-IR and MBCI were significantly higherin T2DM patients with obesity than those in the groups with normal weight and over-weight ( P < 0. 05 ).AI30/AG30 in obesity group was significantly higher than that in the group with normal weight (P <0. 05).Multiple linear regression analysis showed that BMI independently correlated with HOMA-IR ( P < O. 05 ).Sub-group analysis showed that △I30/△G30 and MBCI were significantly higher in those aged 60 years and over with obesity than those in the groups aged less than 60 years ( P < 0. 05 ). Conclusions Non-obese patients with newly diagnosed T2DM have more severe impaired insulin secretion than that in obese ones,and their insulin resistance increases with BMI. Age has no significant correlation with pancreatic beta-cell function or insulin sensitivity.

OBJECTIVETo investigate the effects of prostate stromal cells from different zones of normal prostate tissue on the growth of prostate cancer cells and their action mechanisms.
METHODSWe extracted stromal cells in the fresh normal prostatic tissue derived from the peripheral zone (PZ) or transitional zone (TZ), amplified them in vitro, and used the supernatants of the cells as conditioned media to culture hormone-resistant prostate cancer DU145 cells. We measured the growth curve of the tumor cells using the CCK8 method, determined the number and viability of the cells by trypan blue staining, evaluated their invasiveness by scratch test, and detected the effects of the stromal cells on the key enzymes in the glycolysis of the tumor cells by Western blot.
RESULTSThe conditioned medium with the PZ-derived stromal cells promoted, while that with the TZ-derived stromal cells inhibited the growth of the tumor cells. The former significantly increased, while the latter markedly decreased the expressions of the key enzymes hexokinase 2 (HK-2), pyruvate kinase 2 (PKM-2), lactate dehydrogenase (LDHA), and pyruvate dehydrogenase (PDH) in the glycolysis of the tumor cells.
CONCLUSIONProstate stromal cells from different zones exert different influences on the growth of tumor cells, which may be associated with their different effects on the glycolysis of tumor cells.
