Kidney theory is an important figure in traditional Chinese medicine (TCM), it proposes that the kidney is the root of life, in which stores congenital essence and energy of human body that promotes reproduction, growth and development. The facts that body development begins from oosperm have long been elucidated in modern medicine and life science. Furthermore, oosperm is a totipotent stem cell. The totipotent stem cell with its derived embryonic stem cell (ESC) and stem cell constitute the source of growth, development and tissue regeneration. It is rational to comprehend ESC by means of the Kidney theory of TCM, investigate the effect of Kidney-nourishing on the activities of ESC, such as proliferation, aging and apoptosis, and on its related genes regarding transcription, expression and functional regulation. Our works have suggested that classical Kidney-yin-nourishing herb formula Zuo-gui-wan could inhibit the ESC differentiation and apoptosis, stimulate proliferation, and promote the process of cell cycle. These observations coincide with up-regulate expression of Wnt and Oct3/4, and down-regulate expression of P16INK4a. At the same time, classical Kidney-yang-nourishing herb formula You-gui-wan could inhibit ESC apoptosis induced by H2O2, up-regulate Notch expression and down-regulate P16INK4a expression. In addition, there have been some evidences indicated Kidney-nourishing could promote mesenchymal stem cells proliferate. These observations strongly suggest that, Kidney theory of TCM, as the root of the life, is associated with ESC and stem cell; it may provide insight into Kidney theory of TCM and stem cell research.

Objective To evaluate the comprehensive experiment in fundamental nursing by using the indicator system and analyze the teaching effect.Methods 450 nursing graduates of grade 2011 were divided into 56 groups and comprehensive experiments were graded by using the indicator system in each group.Results The four indexes in level one scored (18.08±1.50),(19.99±2.31),(28.18±3.35),(18.16±1.73) points and accounted for 90％ 、80％ 、81％、91％ respectively.The total points' scorings and proportions were (84.41±5.84) points and 84％ respectively.Some deficiencies were found to be improved during evaluation.Conclusions Nursing comprehensive experiment evaluation indicator system can assess comprehensive experiments well,and the related competencies of nursing graduates need to be improved.

Objective To explore the siqnificance of event related potential(ERP) N400 on stroke patients with aphasia and provide theoretical basis for clinical operations.Methods 29 stroke patients with aphasia(aphasia group) and 58 stroke patients without aphasia(control group) were selected,which were examined with N400.The latency and amplitude of N400 were compared between the two groups.Results The difference waves' latency and amplitude of aphasia group were longer and higher than those of control group.The difference had statistical significance (all P ＜ 0.05).Conclusion N400 is a significant marker for the language disturbance of aphasia patients.

Objective To investigate the permeability changes of prostate cancer cells membrane under low intensity ultrasound in vitro.Methods The culture of monolayer adherent LNCaP prostate cancer cells in six-well plate was exposed to continuous ultrasound at frequency of 1 MHz.The cells membrane permeability (stained with Calcein)and cells viability(stained with PI)were evaluated by fluorescent microscope (FM) and cells morphological changes were evaluated by scanning electron microscope (SEM) under ultrasound with acoustic intensity of 160 mW/cm2 for 5 s.The rate of cells with increased cells membrane permeability as function of acoustic intensity (80 mW/cm2,120 mW/cm2 and 160 mW/cm2,for 5 s) and exposure duration (5 s,10 s and 15 s,acoustic intensity of 120 mW/cm2) was evaluated by flow cytometry.ResultsAfter low intensity of ultrasound,the cells with increased cell membrane permeability could be clearly shown with Calcein uptake under FM while no cell showed Calcein uptake in the control group.The SEM showed less microvilli on the cells after low intensity of ultrasound exposure and few cells showed holes on the cell membrane.The rate of cells with increased membrane permeability increased with acoustic intensity and exposure duration.Conclusion Low intensity ultrasound alone could increase membrane permeability of prostate cancer cells and cells with increased membrane permeability showed surface plane,uncommon holes on the cells membrane.The rate of cells with increased membrane permeability positively correlated with acoustic intensity and exposure duration.

Objective: To observe the effects of Tenglong Buzhong Decoction (TLBZD), a compound traditional Chinese herbal medicine, on proliferation and apoptosis of colon carcinoma cell line LS174T in vitro. Methods: Human colon carcinoma cell line LS174T and human colon epithelial cell line CRL-1790 were treated with different doses of TLBZD. Cell proliferation was detected with cell counting kit-8 (CCK-8) assay and clone formation assay. Cell cycle and apoptosis were detected by flow cytometry, and caspase-3, -8 and -9 activities in LS174T cells were detected by colorimetric assay. Results: TLBZD had no obvious cytotoxicity in normal CRL-1790 cells. After 72-hour treatment of 1 mg/mL TLBZD, or 48- and 72-hour of 2 mg/mL TLBZD, or 24-, 48- and 72-hour of 5-20 mg/mL TLBZD, proliferation of LS174T cells was significantly inhibited. Clone formation of LS174T cells was significantly inhibited by 1 to 20 mg/mL TLBZD treatment. TLBZD at doses of 5 to 20 mg/mL also induced apoptosis and cell cycle arrest at G(0)/G(1) phase in LS174T cells. In addition, caspase-3, -8 and -9 activities were significantly elevated after 5 to 20 mg/mL TLBZD treatment. Conclusion: TLBZD can inhibit cell proliferation, arrest cell cycle at G(0)/G(1) phase, and induce apoptosis in LS174T cells, which may be related to activating of caspase-3, -8 and -9.

Cell senescence is an important anti-cancer mechanism and may contribute to cancer therapeutic outcome. The present study observed the effects of Tenglong Buzhong Decoction (TLBZD), a Chinese herbal formula, on senescence in human colon carcinoma LS-174-T cells.

Objective To investigate the relationship between the different deep venous drainage patterns in the brain and the perimesencephalic subarachnoid hemorrhage (PMSAH).Methods From January 2014 to January 2017,the clinical data of 90 patients with subarachnoid hemorrhage (SAH) diagnosed and treated in the Second Affiliated Hospital of Anhui Medical University were analyzed retrospectively.Thirty patients with PMSAH were in a PMSAH group and 60 patients with aneurismal SAH were in a control group.Unilateral cerebral hemisphere venous drainage was divided into type A (normal continuous):the basilar vein had deep middle cerebral vein drainage and was drained into the great cerebral vein of Galen;type B (normal discontinuous):there was discontinuous venous drainage between the basal vein and the anterior uncal vein and the posterior Galen vein;type C (primitive variant):did not drained into great cerebral vein of Galen,perimesencephalic vein was drained into the superior petrosal sinus or basal vein was directly drained into the transverse sinus or straight sinus.The different combinations of bilateral cerebral hemisphere venous drainage were divided into normal type drainage (typeⅠ:AA),discontinuous type drainage (types Ⅱ:AB or BB),and primitive type drainage (types Ⅲ:AC,BC,or CC).The differences of venous drainage between the two groups were compared.Results In the PMSAH group,both types Ⅰ and Ⅱ drainages accounted for 26.7％ (n=8 in each type) and type Ⅲ accounted for 46.7％ (n=14).In the control group,typeⅠaccounted for 48.3％ (n=29),type Ⅱ accounted for 28.3％ (n=17),and type Ⅲ accounted for 23.3％ (n=14).There were no significant differences in the distribution of three venous drainage patterns between the two groups (χ2=5.804,P=0.055).However,there was significant difference in the types Ⅲ venous drainage between the two groups (χ2=5.081,P=0.024).Conclusion Most of the deep cerebral venous drainage in patients with PMSAH showed basilar venous drainage into the venous sinuses of dura mater,but not to the large cerebral vein drainage,suggesting the way of primitive drainage into the dural sinus was more prone to rupture compared with that of drainage into large cerebral veins.
