According to traditional Chinese medical theory"Qi in motion can normalize blood circulation". To study the therapeutic effect of herbs regulating Qi on inhibition of tumor metastasis,their influence on blood stasis was investigated. Results showed that the herbs could slow down platelet aggregation and normalize the balance between TXA2 and PGI2. Hence,the herbs could inhibit tumor growth and metastasis.

Objective To test using musculoskeletal ultrasound (MSUS) to observe uncovertebral joints (UJs) and to explain the ultrasound images of UJs and their adjacent tissues,especially the vertebral artery (VA).Methods MSUS was used first with human skeletons and cadavers to localize the UJs and VA on the MSUS images with the aid of implanted needles.MSUS was then used with a patient clinically diagnosed with cervical spondylosis of the vertebral artery type (CSA) to detail the image of a normal UJ and its relationship with the adjacent tissues,especially the VA.Whether there was a lateral spur from the uncinate process (UP) was assessed to try to establish a method for measuring osteophytes.Results During the examination the patient was in supine,the neck was elevated 15cm with a pillow and was at 45 degrees of rotation to the contralateral side.The probe was placed at the medial border of the sternocleidomastoid muscle.When the longitudinal section of the common carotid artery was shown,the probe was slowly moved laterally until the VA first appeared,and then was moved up along the VA.Once the VA entered the transverse foramen,moving the probe slightly allowed the UJ behind the VA to be seen between two transverse processes.The UJ thus lies between two transverse processes,that is,between the lateral margins of two vertebral bodies and outside the intervertebral disc.The echo of the lateral border of the UP is on a straight line with the echo of the lateral margin of the vertebral body,with the VA in front of the line.It was noticed that the image of a UP with lateral osteophyte formation crossed the line and reached closer to the VA.The transverse diameter of the UJ was measured as the distance from a line cutting the lateral cortical margin of the cervical vertebra to the outer cortical margin of the lateral UP.Conclusion MSUS can clearly show the UJ and its adjacent tissues,especially the VA.It can be used to assess and measure UJs with lateral osteophyte formation.

OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.

METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.

RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).

CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

Objective To study the application effect of feedback training mode on new neonatal recovery technology.Methods 101 midwives,obstetric doctors and pediatricians who participated the training were tested about the professional knowledge and skills of new neonatal recovery technology according to the teaching material of neonatal asphyxia recovery and neonatal resuscitation guidelines (2007 revision in Beijing).The results showed no statistical significance.And they were randomly divided into the control group (51 cases) and the observation group(50 cases).The control group adopted traditional method,that was,the teacher taught first and then the students took practice.The observation group used feedback training method.Results The theoretical and technical results of the observation group were significantly higher than those of the control group.The learning motivation,learning initiative,cooperation degree,ability of observation and solving problem and operation proficiency were also significantly higher than those of the control group.Conclusions Feedback training methods can significantly increase the learning effect of perinatal personnel,and make popularized the new neonatal recovery technology.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.

Objective To investigate the factors influencing basic rehabilitation service needs of people with disability at Zhabei District in Shanghai .Methods Primary rehabilitation demands and services of 10 311 disabled persons in Zhabei District were surveyed.Results The screening rate of persons with disability having primary rehabilitation demands was 83.5%. And the gender, age, type of disability, disability level, education, employment might be the factors affecting the primary rehabilitation demands of people with disability.Conclusion The primary rehabilitation service demands vary in deferent types of people with disability. The various services based on the extensive rehabilitation services should be provided to deferent categories of people with disability.

Objective To understand the status of special rehabilitation service demands of people with disability at Zhabei District in Shanghai and to provide the basis for the policy development.Methods Screen rate (SR) was used to indicate the level of demand of rehabilitation service, the data were analyzed with SPSS 13.0 statistical software.Results There were 4 349 persons with disability who demanded the special rehabilitation service; the SR of “on-site rehabilitation service” demands was the highest among the whole persons with disability; the SR of “personalized allotment of supplies and appliances” demands of the intellectual disability and mental disability was lower than the other types; the SR of special rehabilitation service demands of the female, the elderly, the low cultural level, the unemployed and the people with severe disability were relatively higher.Conclusion The form of “on-site rehabilitation services” needs to improve based on the demand of the disabilities; “personalized supplies and appliances” for the intellectual disability and mental disability needs to further develop; the rehabilitation services targeted to the female, the elderly, the low cultural level, the unemployed and the people with severe disability need to improve.

Objective To provide the advice on how to optimize the allocation of resources and make other policy through the analysis factors affecting rehabilitation services needs of people with disability at Zhabei district in Shanghai.Methods The factors affecting rehabilitation services needs such as types of disability, disability levels, education, employment, marital status, age and sex were analyzed with Logistic analysis.Results The factors affecting primary rehabilitation services were types of disability, education, employment situation, marital status and sex.
