Objective To investigate the cognitive function of patients with prostate cancer after maximal androgen blockade therapy and its influenced factors,and to provide a new way for early prevention strategy.Methods Montreal cognitive assessment (MoCA),hospital anxiety depression scale (HAD),social support rating scale (SSRS) and self-designed questionnaire were used in 56 cases treated with maximum androgen blockade therapy for more than six months and 37 cases who underwent radical prostatectomy treatment to evaluate their cognitive function and collect the observation indexes between January 2013 and October 2015.Based on MoCA score,all patients were divided into cognitive dysfunction group (n =40) and normal cognitive function group (n =53).The observation indexes in two groups were compared and cognitive function with different treatment in two groups were analyzed.The changes on the influencing factors of cognitive function in patients were filtered using multivariable logistic regression analysis.Results In the cognitive dysfunction group and normal group,the proportion of MAB treatment was 80.0％ (32/40) vs.45.3％ (24/53),the age was 73.7 vs.73.7 years,the proportion of solitary was 32.5％ (13/40) vs.13.2％ (7/53),the proportion of depressive symptoms was 87.5％ (35/40) vs.62.3％ (33/53),the social support level was 32.5 vs.41.1 and the proportion of testosterone decreased was 95.0％ (38/40) vs.45.3％ (24/53).All events showed statistically significant differences (P ＜0.05).Compared MAB treatment group with radical surgical treatment group,the testosterone level was (0.27-±O.15) vs.(12.14 ± 1.86) nmol/L,visual space and executive function score was 4.18 ±0.79 vs.4.54 ±0.56,attention score was 4.73 ±0.99 vs.5.16 ±0.79,delayed memory score was 3.75 ± 1.21 vs.4.30 ± 1.05 and MoCA score was 26.13 ± 1.48 vs.27.27 ± 1.39,which all showed the statistically significant difference (P ＜ 0.05).The results of multiple regression analysis showed that age (OR =1.183,95％ CI 1.135-1.223),depressive symptoms (OR =1.092,95％ CI 1.047-1.149),social support (OR =0.897,95％ CI O.838-0.956),testosterone (OR =2.105,95％ CI 1.369-4.083) were the influenced factors of cognitive dysfunction.Conclusions The incidence of cognitive dysfunction in patients with prostate cancer after maximal androgen blockade therapy more than six months was higher than others.Age,depression,social support level and testosterone levels were related to the occurrence of cognitive dysfunction.

BACKGROUND:Impaired balance between osteogenesis and adipogenesis of bone marrow mesenchymal stem cels is a crucial pathological mechanism of osteoporosis. Mechanical loads applied to bone tissue can increase bone formation and improve bone strength, and meanwhile lead to the release of extracelular nucleotides, such as adenosine triphosphate.
OBJECTIVE: To determine the effects of adenosine triphosphate on the osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cels and to investigate the underlying mechanisms.
METHODS:The effect of adenosine triphosphate (10, 50, 250 μmol/L) on differentiation of bone marrow mesenchymal stem cels were measured by osteogenic and adipogenic related genes expression, alizarin red staining and oil red O staining. The activation of ERK1/2 signaling pathway by adenosine triphosphate was tested using western blot assay.
RESULTS AND CONCLUSION: Incubation of bone marrow mesenchymal stem cels with adenosine triphosphate resulted in the dose-dependent increase of osteogenic genes expression and calcium deposition, and inhibition of adipogenic genes expression and lipid droplet formation, but had no effects on cel proliferation. Adenosine triphosphate activated ERK1/2 signaling pathway, and U0126 as an ERK1/2 inhibitor restrained the effect of adenosine triphosphate on the differentiation of bone marrow mesenchymal stem cels.

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P＜0.001; LM: t = 9. 346, P＜0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

OBJECTIVEUsing methods of clinical scale assessment and cerebral functional imaging to compare the relative specificity of needling acupoints Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) in intervening vascular dementia (VD) in different areas in the brain.

METHODSFifty patients with VD were randomized into 5 groups. Needling on conventionally used acupoints of hand and foot three Yang-meridians aiming at hemiplegia was applied to the patients in Group A, and needling on DU20 to Group B, on DU26 to Group C, on HT7 to Group D and on all the three to Group E was applied additionally. Assessments of Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Family Attitude Questionnaire (FAQ) were made. And the positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) examinations were conducted in 5 selected patients from each group before and after treatment.

RESULTSNeedling on conventional acupoints plus DU20 could effect the inner temporal system, thalamencephalon system and prefrontal cortical system to improve memory and executive capacity of VD patients; conventional acupoints plus DU26 could effect more to the prefrontal cortical system to obviously elevate the executive capacity; that plus HT7 would reveal an effect similar to but rather weaker than plus DU20, and effect more to memory; and that plus all the three simultaneously could effect rather roundly multiple aspects of the nervous system related to intellectual activities, to elevate the recognition and enhance the executive capacity.

CONCLUSIONNeedling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.
