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 investigate the expression of costimulatory molecules CD80and CD86on peripheral blood lymphocytes(PBLC)in patients with systemic lupus erythematosus(SLE)and its significance.Methods The expression of CD80and CD86on PBLC was measured by flow cytometric assay in30patients with SLE and25normal controls.Results Expression of CD86on PBLC in patients with SLE was significantly lower than that of normal controls(P

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.
