According to the records in Neijing (Internal Classic), this article discusses the relationship during the connotative evolution of mai (vessel) and jing (meridian) in the three aspects, named mai (vessels), the evolution from mai (vessel) to jing (meridian), and the connotation replacement of jing (meridian) with mai (vessel). The study results show that the connotation of Jingmai is originated from mai (vessel), but more enriched, which cannot be confused with each other. The recognition on the connotation of jingmai from mai (vessel) to jing (meridian) is the process of TCM understanding from concretization to abstraction, and from the entity to the concept. Jing (meridian) represents the law on the longitudinal and invariable running course of meridian, differenti from the perspective in western medicine in human body. This law results from the naive observation and is based on the rational summary and thinking, and it stands up the approval from practice. The description of jing (meridian) as mai (vessel) is just the superficial description of this term. In fact, its concept infers to the connotation of meridian.

Objective To understand self-harmonious state of medical college students at present,and explore the relationship between self-harmonious and social avoidance and distress(SAD).Methods 412 medical college students were assessed by self-consistency and congruence survey(SCCS),social avoidance and distal scores were 92.06±12.80).The self-harmonious of medical college students have differences in the grade.sex,one-child and area;and the difierences have not reached the remarkable level of statistics(P＞0.05),but the difference of self-rigidity between male students and female students(male:19.35±4.20;female:17.73±0.372,-0.152).Conclusion The self-harmonious level of medical college students Was low.And the bad SCCS state will lead to social avoidance or anxiety.

Studies have shown that embryonic stem cells and neural stem ceils could be induced to differentiate into motor neurons by adding inducing factors to the culture to improve differentiation proportion of motor neurons. The development and maturation process of motor neurons in vitro culture is similar to that in embryo, involving participation of Pax6, Nk×6.1, Olig2 and HB9. Moreover, cells with HB9 as separation mark almost differentiate into motor neurons in vitro. In addition, other types of protein marks have been used for identification of motor neuronal induced differentiation, such as neuron mark MAP-2, β-tubulin-Ⅲ, cholinergic cell mark ChAT, VAChT, Schwann cell mitogen REG2, and voltage-dependent calcium ion channel 11.2 subunit. The identification of induced differentiation of motor neurons also involves detection of function of differentiated motor neurons by two methods. One method is to detect the function of in vitro cultured motor neurons, and the other is to detect the function of transplanted motor neurons in vivo. Although induced differentiation of stem cells into motor neurons becomes mature, many issues remain in clinical application, such as cell sources of induced differentiation of motor neuron, efficiency of induced differentiation, purification of differentiated motor neurons, and function of motor neurons.

BACKGROUND: The main pathological change of intervertebral disc herniation is that nucleus pulposus protrudes from ruptured annulus fibrosus, thus we can hypothesize that it is possible to prevent disc herniation prior to its protrusion by coagulating it as a whole.OBJECTIVE: To observe the coagulation effects of intervertebral disc nucleus pulposus by alum solution.DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed between September 2002 and April 2003 at Department of Animal Experiment, Peking University First Hospital, Beijing China.MATERIALS: Twenty-six healthy adult hybrid dogs, 9 for in vitro experiment and 17 for in vivo experiment, weighing 16-21kg, with no restrictions on male and female, were obtained from Department of Animal Experiment, Peking University First Hospital, Beijing, China.METHODS: Twenty canine in vitro intervertebral discs obtained from 5 dogs were randomly divided into 4 groups, with 5 discs in each group, and were put into 2.5%, 5%, 10% alum solutions and 0.9% physiological saline, respectively. Effects of disc coagulation were observed after immersing for 1 day and 10 days, respectively. Another 16 in vitro intervertebral discs obtained from 4 dogs, composed of L2/3, L3/4, L4/5, L5/6, were also injected with the above 4 experimental solutions, 0.15ml, respectively. Sixty-eight in vivo intervertebral discs were obtained from 17 dogs and divided into 4 groups: blank control group, physiological saline group, 10% alum solution+one puncture point group, and 10% alum solution+two puncture points group, 17 discs in each group. Harvesting time: 3 days, 2 weeks, 1 month and 3 months postoperation.MAIN OUTCOME MEASURES: Effects of alum solutions on the coagulation of the intervertebral discs and related histological changes were observed and an alum solution of suitable concentration was preliminarily selected. General observation, light microscopic observation and scanning electron microscopic observation were made of the nucleus pulposuses.RESULTS: In the in vitro and in vivo experiments, it was found that physiological saline did not produce the effect of coagulation on the nucleus pulposus, while immersion in the alum solution induced nucleus pulposus coagulation in the in vitro intervertebral discs. Also, as the concentration of the alum solution increased, the volume of the coagulated nucleus pulposus gradually decreased. After alum solution was injected into the in vitro intervertebral discs, no nucleus pulposus coagulation appeared. When the 10% alum solution was injected into the in vivo intervertebral discs, nucleus pulposus coagulation occurred, with the strongest coagulation effect reached at 1 month postoperation. This was manifested in the agglutination reaction centered around the puncture point. When there were 2 puncture points, 2 coagulated lumps might appear. There was an increase in the mesenchymal component of the coagulated nucleus pulposus. Histochemical and scanning electron microscopic examinations confirmed the proliferation of large numbers of collagen fibers in the mesenchyme.CONCLUSION: Alum can promote nucleus pulposus to coagulate around the injection point. This may be related to the increase of collagens and the fibrosis resulting from stimulation of the nucleus pulposus by alum solution.
