ObjectiveTo study the missing items in questionnaire cfidentification for TCM constitution.MethodsThe questionnaires were regarded as study objects,which were independently finished by 1322 participants in Changfeng community who were over 45 years and agreed to participate in.The data'was analyzed by SPSS.ResultsMissing items were found in the questionnaires,with a missing rate of 33.74％ on an overall basis.No statistic difference was noted between male and female (x2=0.67,P＞0.05).The rate of missing items increased as participants' age climbing up to the age of 80,and then decreased.Groups characterized with age and gender showed difference in missing items.89.69％ of the incomplete questionnaires had less than 3 missing items,which concentrated in some specific items.ConclusionAttention should be addressed to the fact that missing items were found in questionnaircs of identification for TCM constitution finished independently by residents.

The strength model of self-control suggests that the exertion of self-control depends on a limited resource. Intervention studies over the years have aimed to improve participants'self-control via increasing their ca-pacity for the resource or decreasing their consumption of it. We conducted a review of the literature to provide summarized updates on the advances made in the intervention studies that have been conducted based on the strength model. The findings suggest that various behavior-training methods can build greater capacity for self-con-trol resource. Meanwhile,several behavior-training methods,mindfulness,and ingestion of glucose may also effec-tively slow down or enhance the recovery of ego-depletion. Future studies may further explore the mechanisms through which the behavior-training exert its positive influence. Similarly,to improve the ecological validity,it is recommended that future studies pay more attention to a wide range of self-control tasks. Qualitative studies are also wanted. Additionally,to improvethe daily life applications of the various intervention techniques,these sorts of stud-ies have the propensity to improve the practical significance of the strength model of self-control.

Forty rats were selected for the experiment, which were divided into three groups including experimental ulcer group, normal saline and normal control groups. The pancreatic tissue were prepared for immunohistochemical staining at 6th, 10th, 14th, and 21st day after operation. Sternberger's PAP method was used to show the glucagon cell (A cell) and insulin cell (B cell) in order to observe their changes during the experimental peptic ulcer. In normal control group, the percentage of A cells is 23.31?1.91 (X?SD) and that of B cells is 73.1?4.01. But in experimental ulcer group, the A cell percentage is raised up to 42.6?5.59 and the B cell percentage is lowered down to 57.5?4.55 on the 10th day after operation. Comparing with normal saline group and normal group their differences show statistical outstanding differences. The result may point out that both A and B cells of pancreatic islet take part in the body's natural resistance against the disease, especially A cells.

Sixty five adult male rats were selected for the experiment. The rats were divided into three groups. Peptic ulcer was induced in the experimental group by means of injection of acetic acid to the submucosa of the stomach. Animals of the control group were injected with normal saline instead. Another control group consisted of normal rats without any treatment. All rats were killed at different time intervals (2-28 d) after the operation. The pancreas tissues were prepared for enzyme histochemical study. The results were observed as follows: Two to four days after the peptic ulcer operation, in the pancreatic A-cells, the activity of alkaline phosphatase (A1P) decreased and 5-nucleotidase (5-Nase) activity increased. A1P, adenosinc triphosphatase(ATPase),succinic and lactic dehydrogenases(SDH, LDH), glucose-6-phosphate and a-glycerophosphate dehydrogenases(G-6-PD,orGPD)acuvities were rasied in varying degrees and returned to normal level after 28 days of the operation. In the pancreatic B-cells, during the early stage of the peptic ulcer, acid phosphatase (AcP) and 5-Nase activities increased and ATPase activity declined. But after four days, AcP, 5-Nase, SDH and LDH activities declined, then began to recover and returned to normal level after twenty one days of the operation. In the normal saline operation control group, the changes of A- and B-cells, two to four days after the operation were the same as in the peptic ulcer group and returned to normal level during the period of six to ten days. The above histochemical changes showed that the pancreatic A- and B-cells played a certain role in the recovery of the experimental peptic ulcer.

Stem cell therapy provides immense hope for restoring the impaired cardiomyocytes .However, it has been debated on the effectiveness , mechanisms , and survival of the donated cell population in the ischemic myocardial milieu .Protective paracrine effect of stem cells on cardiomyocytes gradually arose great attentions .Exosomes , as typical representative of paracrine effect of stem cells, are 30-100 nm in size and tiny microvesicles released by cells in response to different physiological states , and enriched in pro-teins, messenger RNAs, and miRs characteristic of parental stem cells , represent great potential for treating cardiovascular diseases . Recent studies show that exosomes from different kinds of stem cells can effectively promote cardiac function by means of promoting the donated cell survival , proliferation and angiogenesis in the ischemia heart .The aim of this review is to summarize current research ef-forts on exosomes from different kinds of stem cells , including their potential mechanism to develop a potentially viable therapy for the treatment of impaired cardiomyocytes via promoting cardiomyocytes survival , proliferation and angiogenesis;inhibiting inflammatory re-sponse and cardiac fibrosis after myocardial infarction .

Objective To analyze the present situation about early screening of developmental dysplasia of the hip( DDH) of infants in Shapingba district of Chongqing,and to explore the methods to improve the rate of diagnosis about DDH. Methods A total of 2 066 infants among 0~6 months old living in Shapingba district of Chongqing,were examined with clinical and ultrasound method on hip. Results Six infants with DDH were discovered among the 2 066 infants,which was more common in the female baby. The deficiency of hospital in which can exam hip with ultrasound method and the deficiency about DDH were the significant factors affecting the low detection rate. Conclusion Necessary measure must be taken to improve the low detection rate of DDH.

BACKGROUND: Direct observation of infarcted microvaseular perfusion after cerebral infarction is the most immediate evidence in evaluation of therapeutic effects.OBJECTIVE: To observe dynamic changes in flowing quality and field in cerebral ischemic area in rats so as to qualitatively and quantitatively analyze the microvascular state in pia matral encephali ischemic area and the changes of associated leukocytic flowing velocity and flowing morphology.DESIGN: Randomized controlled experiment was designed.SETTING: Department of Acupuncture and Moxibustion of General Hospital Chinese PLA.MATERIALS: The experiment was performed in Research Room of Microcirculation of General Hospital Chinese PLA, in which, 120 female Wis tar rats of 2-month old were employed and randomized into acupuncture group (36 rats), model group (36 rats), sham-operation group (36 rats) and normal group (12 rats). The first 3 groups were subdivided in 3 hours, 6hours and 24 hours groups according to the prescriptive time divisions, 12rats in each group.METHODS: In acupuncture and model groups, after abdominal anesthesia with pentobarbital sodium, the cranium was opened and the occlusion of meddle cerebral artery was performed in cerebrum with heat-coagulation method. In sham-operation group, anesthesia and cranium opening were performed, but the meddle cerebral artery was not occluded. In normal group, no any management was performed. In acupuncture group, 60 minutes after occlusion of meddle cerebral artery in cerebrum, needling was given on Renzhong (GV 26) and Neiguan (PC 6) with electric stimulation of disperse-dense wave, 4-10 Hz frequency and 0.4 V of intensity, lasting for 5 minutes. Afterwards, pecking-acupuncture technique was done on Renzhong (GV 26) to achieve strong stimulation for 10 seconds. In shamoperation and model groups, the rats were in process of grasping and fixation, but acupuncture was not applied. Vascular endotheliocyte fluorescence staining and leukocyte fluorescence tracing method were applied, in combination with microscopic video system and computer imaging analyzing system, to observe in dynamic and quantitatively the influences of acupuncture on pia matral encephali microvascular morphology, density and blood flowing velocity at 3 hours, 6 hours and 24 hours after cerebral occlusion of meddle cerebral artery.morphology, density and blood flowing state at various time divisions observed directly microscopically and vascular endotheliocyte morphology and the state of brain tissue which near the microvascular after infusion with velocity in infarcted area at various time divisions measured in quantity in each group.microvascular endotheliocytes were colored worse and more fluorescent exudation appeared. Those were better remarkably in acupuncture group ty: That in model group was lower than normal group. That at 3 hours, 6hours and 24 hours in acupuncture group was higher remarkably than model group [(6.92±0.42), (3.25±0.52) pces/visual field; (7.61 ±0.51),(3.68±0.32) pces/visual field; (8.24±0.72), (5.49±1.2) pces/visual leukocyte velocity: That in model group was lower remarkably in normal group. That at 3 hours, 6 hours and 24 hours in acupuncture group was higher remarkably than model group [(1 193±358), (600±261) μm/s;(1 112±267), (517±115) μm/s, (1 766±293), (611±291) μm/s, q=4.608.28, P ＜ 0.01].CONCLUSION: At early stage of cerebral infarction, broken blood flow is severe in artery, vein and capillary in ischemic area; the numbers of opened vessels are few, flow rate is slow down and cerebral perfusion is unsatisfactory. Acupuncture amaliorate the microcirculation perfusion state in ischemic area, increases the numbers of opened vessels and improves flowing morphology of blood cell.
