Psychosomatic medicine studies on interaction between body and mind,etiology,pathology,diagnosis,and prevention of psychosomatic diseases.TCM has no concept of psychosomatic medicine,but studies result from research progress of psychosomatic medicine suggested that TCM had obvious advantages in treating these kinds of diseases.

It is an important topic in life science research to study the method of intervening sub-health. Previous studies indicated that traditional Chinese medicine (TCM) has unique advantages in sub-health intervention. In this paper, TCM sub-health intervention was summarized from such aspects as diagnosing according to syndrome differentiation, application of herbal medicine and Chinese patent medicine, herbal cuisine and medicated bath. At the same time, the paper discussed methods of sub-health comprehensive intervention, the relation between individual physical factors and sub-health, and the potential influence of the sub-health intervention on the innovation of Chinese medicine health insurance.

Based on the literatures in MEDLINE database and EMBASE databases this article has carried out a bibliometrics study on foreign clinical researching institutions of acupuncture and moxibustion to screen those institutions who had more published articles as our major cooperation and exchange objects in the future,hoping for providing information basis of TCM international scientific research.

Non-Drug Therapy has good advantages for sub-health state.Commonly used methods of non-drug therapy are health education,life conditioning,physical exercise,psychological adjustment,acupuncture,massage and etc.TCM has obvious advantages in the field of non-drug therapy,showing broad prospects.

Objective To analyze the etiology and prognosis of children with thrombocytopenia (TP) in pediatric intensive care unit (PICU). Methods The data of children with TP (exclusion of congenital and unknown TP) admitted to PICU of Anhui Provincial Children's Hospital from January 2008 to December 2017 was analyzed retrospectively. According to the age of onset, the children were divided into infantile group (29 days to less than 1 year), early childhood group (1 to less than 3 years), preschool group (3 to less than 6 years), school age group (6 to less than 10 years) and puberty group (more than 10 years). Moreover, according to the lowest platelet count (PLT), the children were divided into PLT≤20×109/L group, PLT (21-50)×109/L group and PLT > (50-100) ×109/L group. The distribution and mortality of TP were analyzed, and the relationship between age, PLT decrease and prognosis were analyzed by Pearson method. Results Among 6 725 children admitted to PICU in our hospital from January 2008 to December 2017, there were 683 children with TP, with the incidence of 10.2%. Among 683 children with TP, there were 387 males and 296 females, with the median age of 2.72 (0.61, 3.08) years, and 92 children died, with a total mortality of 13.5%. Analysis of primary disease showed that TP caused by non-hematological malignant tumor disease accounted for 73.9%, with the mortality of 11.1% (56/505). TP induced by hematological malignant tumor disease accounted for 21.4%, with the mortality of 24.7% (36/146). Pseudothrombocytopenia accounted for 0.6%, with the mortality of 0% (0/4). Other children who gave up treatment accounted for 4.1%. It was shown by further analysis that multiple organ dysfunction syndrome (MODS) caused by TP associated with non-hematological malignant tumor disease accounted for 26.9%, with the mortality of 15.4% (21/136). Sepsis, severe trauma, pneumonia, central nervous system infection and disseminated intravascular coagulation (DIC) accounted for 17.4%, 16.6%, 12.7%, 11.7% and 11.5%; with the mortality of 8.0% (7/88), 2.4% (2/84), 0% (0/64), 20.3% (12/59) and 24.1% (14/58), respectively. The main causes of TP associated with hematological malignant tumor disease were hemophagocytic syndrome [accounting for 27.4%, with the mortality of 32.5% (13/40)] and bone marrow inhibition [accounting for 21.2%, with the mortality of 25.8% (8/31)]. The younger were the children with TP, the higher would be the mortality. The mortality of infantile group was significantly higher than that of early childhood group, preschool group, school age group and puberty group [18.8% (53/282) vs. 14.0% (28/200), 6.7% (7/104), 4.3% (4/92), 0% (0/5), all P < 0.01]. The lower was the PLT, the higher would be the mortality. The mortality of PLT≤20×109/L group was significantly higher than that of PLT (21-50)×109/L group and PLT > (50-100)×109/L group [18.1% (39/215) vs. 13.0% (32/247), 9.5% (21/221), both P < 0.05]. It was shown by correlation analysis that there was no association between age and 28-day death time in children with TP (r = -0.037, P = 0.727), but PLT was positively correlated with 28-day death time in children with TP (r = 0.844, P = 0.010). Conclusions MODS, infection, sepsis, severe trauma and DIC are the common causes of TP in PICU. The younger are the children with TP, the lower is the PLT, and the worse would be the prognosis.

BACKGROUND:The differentiation of neural stem cells (NSCs) is a hot research. Whether brain-derived neurotrophic factors (BDNF) can induce the differentiation of NSCs into neurons has not been detailed studied. OBJECTIVE:To investigate the effect of different concentrations of BDNF on the differentiation of NSCs from adult rat hippocampus into neurons in the medium with epidermal growth factor. DESIGN:A controlled study. SETTING:Department of Human Anatomy, China Medical University. MATERIALS:The experiment was performed at the Neurotomia Laboratory of China Medical University in August 2007. NSCs isolated from hippocampus of adult SD rats were inoculated in a serum-free medium. Three clean adult SD rats (200-250 g each) were provided by Laboratory Animal Department of China Medical University. Dispositions to the rats were consistent with ethical standards of animals. Epidermal growth factor (EGF) and BDNF were bought from R&D Company. METHODS:①NSCs obtained from rat hippocampus were cultured in the serum-free medium containing basic fibroblast growth factor (bFGF), EGF and B27. ②Single cell clone was obtained via limited dilution for the fourth passage of cells. Identification of NSCs for the passage of cells from monoclonal spheres was performed by Nestin immunocytochemistry. Neurons and astroglial cells were identified by immunocytochemistry for neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP) a week after differentiation. ③Differentiation for the monoclonal spheres was done to appraisal the proportion of neurons. NSCs were divided for several groups containing 0 μg/L, 50 μg/L, 100 μg/L, 150 μg/L, and 200 μg/L groups according to the doses of BDNF. EGF was added in the media of each group. Immunocytochemistry for NSE was done a week later to count the positive cells. MAIN OUTCOME MEASURES:Proportion of neurons differentiated from NSCs.RESULTS:①NSCs immunocytochemical staining showed that Nestin was positive in monoclonal spheres, and NSE and GFAP were positive in differentiated cells. ②The proportion of differentiation from NSCs into neurons was significantly higher in groups treated with 50 μg/L and 100 μg/L BDNF compared to other groups（t=2.502-5.025, P < 0.05）, but there was no significant difference between 50 μg/L and 100 μg/L BDNF groups（P > 0.05）. Moreover, no significant difference was detected among 0 μg/L, 150 μg/L and 200 μg/L BDNF groups (P > 0.05). CONCLUSION:The optimal concentration of BDNF is 50 μg/L for differentiation from NSCs into neurons while the concentration of EGF is 20 μg/L.

From the perspective of efficacy evaluation based on the literatures of MEDLINE database,the study carries out a bibliometrics study on domestic and foreign acupuncture clinical trials of the past three decades.The study involves the statistical classification on different systems and diseases,as well as statistics of diseases species on RCT or non- RCT involved,which will provide ideas and directions on diseases selection for the efficacy evaluation and re-evaluation researches in the field of evidence based medicine.

Taking Science Citation Index Expanded (SCI-Expanded) as information source,and using methods of bibliometric analysis,Chinese Medicine international co-authored articles which published from 1998 to 2010 were statistically analyzed on publish year,document growth,active fields,etc.,aiming to look for status and trends in International Collaboration of the Traditional Chinese Medicine,and to be a reference for researchers.

OBJECTIVETo observe the intervention effect of electroacupuncture (EA) at "Weizhong" (BL 40) on rats with bupivacaine-induced multifidus muscle injury, so as to explore the action mechanism.

METHODSA total of 72 rats were randomly divided into a control group, a model group, a Weizhong group and a Shenshu group, 18 rats in each group. Each group was again randomly divided into a 4-day subgroup, a 7-day subgroup and a 14-day subgroup, 6 rats in each subgroup. Rats in the model group, Weizhong group and Shenshu group were treated with intramuscular injection of 0.5% bupivacaine (BPVC) to establish the model of multifidus muscle injury. Rats in the Weizhong group and Shenshu group were treated with EA at "Weizhong" (BL 40) and "Shenshu" (BL 23), 20 min per treatment, once a day. Each subgroup was treated for 4 days, 7 days and 14 days respectively. Rats in the control group and model group were treated with immobilization. The morphology and cross sectional area (CSA) changes of multifidus with HE and Masson staining at different time points were observed; the expression of insulin like growth factor 1 (IGF-1) and myogenic differentiation antigen (MyoD) was measured by immunohistochemical method.

RESULTSAfter the modeling, there were significant morphology changes of multifidus at different time points, which was not fully recovered after 14 days. The morphological observation in the Weizhong group and Shenshu group was superior to that in the model group. At 7th day, the CSA in the Weizhong group was higher than that in the model group (P < 0.05); at 14th day, the CSA in the Weizhong group and Shenshu group was higher than that in the model group (P < 0.01, P < 0.05). At 4th day and 7th day, the expression of IGF-1 in the model group was higher than that in the control group (both P < 0.01); at 4th day, that in the Weizhong group was higher than that in the model group (P < 0.01), and that in the Weizhong group was higher than that in the Shenshu group (P < 0.05), and that in the Shenshu group was as higher than that in the model group (P < 0.05); at 14th day, that in the Shenshu group was higher than that in the model and Weizhong group (P < 0.01). At 4th day, the expression of MyoD in the Weizhong group and Shenshu group was higher than that in the model group (P < 0.01), which was more significant in the Weizhong group (P < 0.01).

CONCLUSIONElectroacupuncture at "Weizhong" (BL 40) and "Shenshu" (BL 23) can both promote the regeneration of multifidus muscle injury. EA at "Weizhong" (BL 40) has a better effect at early phase, which may be related to the up-regulation of IGF-1 and MyoD and the completion of the proliferation of myoblast in advance.
