ObjectiveTo observe cluster needling of scalp acupuncture combined with rehabilitation(Tang's Approach) as an early intervention for the children with high-risk of cerebral palsy.Methods62 infants with high-risk of cerebral palsy in hospital from Jan. 2006 to Dec. 2008 were divided into the acupuncture with rehabilitation group and rehabilitation group. The scores of Mental Develop Mental Index (MDI) and Psycho-Motor Developmental Index (PDI) were assessed before and 3 months after the treatment. ResultsThe scores of MDI and PDI were better in acupuncture with rehabilitation group than in the rehabilitation group 3 months after the treatment (P＜0.01). There were significant differences in reducing dysfunction in the acupuncture with rehabilitation group compared with the rehabilitation group (P＜0.01). The follow-up result showed that there were certain advantages in reducing incidence of cerebral palsy by the acupuncture combined with rehabilitation. ConclusionAs an early intervention, Tang's Approach can improve motor function in children with high-risk cerebral palsy.

Objective To investigate the toxic effects of rotenone on dopamine transporter in the substantia nigra of the rat. Methods Rats (male) were divided into normal control group, vehicle control group and rotenone experimental group(1.0mg/kg and 1.5mg/kg). The animals were subcutaneously administrated with the vehicle or rotenone in different dosage once a day for 28 days. One day after last injection, the brain was dissected and the substantia nigra was harvested. Protein expressions of tyrosine hydroxylase and dopamine transporter were determined with the methods of immunohistochemistry and Western blot. The mRNA expressions of dopamine transporter and dopamine receptor were detected with RT-PCR respectively. The activity of Na+-K+-ATPase was assayed biochemically. Results In the experimental groups, both the immune positive neurons of tyrosine hydroxylase and the expression of its protein were significantly decreased in the substantia nigra of the rats after rotenone treatment. The number of dopamine transporter antibody-immune positive neurons were significantly increased in the rats exposed to rotenone. Furthermore, protein and mRNA expressions of dopamine transporter in the experimental group were also obviously up-regulated compared with the normal control group. A decreased activity of Na+-K+-ATPase was observed in the substantia nigra of rats in the rotenone experimental group. In addition, the mRNA expression of D2R was also increased in contrast with that in the control group. Conclusions Rotenone is toxic to dopamine neurons in the substantia nigra of rats. Dysfunction of dopamine transporter may be involved in the mechanism of rotenone toxicity to dopamine neurons.

Objective To compare the difference of entrance dose between CR and amorphous silocon DR system in chest imaging, and to discuss their optimum exposure dose. Methods For CR and DR, different entrance dose was measured by dosimeter in chest phantom. The value of IQFinv was analyzed by CDRAD2. 0 software. Image quality difference between CR and DR was assessed by group t-test. The relationship between image quality and entrance dose was tested by using Pearson correlation analysis. The best IQFinv values in CR and DR system were achieved via ROC curve analysis, and the exposure dose was then calculated. Results There were direct correlation values between entrance dose and the value of IQFinv in CR and DR system, respectively( r =0. 893 ,0. 848 ,P < 0. 01 ) . The linear regression equation for DR was IQFinv =0. 0050 +3. 359, and for CR was IQFinv =0. 005D + I. 651 , where D was entrance dose. The difference of IQFinv value between CR and DR was significant(t = 5. 455 ,P < 0. 05). The best IQFinv value of the two groups from ROC analysis was 3.55. Conclusions With the entrance dose increased, the detection ability of contrast-detail was elevated in the two digital radiography systems. With equal entrance dose, the detection ability of DR in contrast-detail was superior to CR. With equal image quality, DR obviously decreased the radiation dose to the patients.

Objective To learn the change of causes sequences, the pattern and dynamic trend of causes of death for the inhabitants in Jiaxing from 2009 to 2014, and to provide a major reference for health decisions and disease control and prevention. Method This study was based on chronic disease surveillance information management data in Zhejiang province from 2009 to 2014. ICD-10 criteria and method was used to classify the causes of death. To evaluate health status of those residents, the relative health indicators such as mortality rate, constituent ratio, PYLL, AYLL, PYLL‰were used. Results The average mortality rate of residents was 691.92/100 000 of Jiaxing from 2009 to 2014, with male 760.73/100 000 and female 624.64/100 000 (the average mortality rate of male was significantly higher than that of female, χ2=455.52, P<0.01). The top five causes of death of local residents were malignant neoplasm, respiratory system diseases, cerebrovascular diseases, injury and poisoning, heart diseases, which accounted for 87.95%of all deaths. The mortality caused by malignant neoplasm was 189.53/100 000, which accounted for 31.90% of five main death causes (the rate of male was significantly higher than that of female, χ2=3767.70, P<0.01). The PYLL of malignant neoplasm were 38 368 years, which was the main reason. The AYLL of injury and poisoning were 9.58 years. Conclusion The average mortality rate of residents has been declining across the Jiaxing, but the mortality rate of malignant neoplasm is increasing year by year. The data suggested that malignant neoplasm, cardiovascular disease, unintentional falls, motor vehicle traffic accidents and pneumonia are major factors affecting the health of the population.

Objective To investigate the clinical efficacy of electroacupuncture plus a multi-function cervical rehabilitation system in treating cervical spondylosis.Methods Sixty patients with cervical spondylosis were randomly allocated to treatment and control groups, 30 cases each. The treatment group received electroacupuncture plus treatment with a multi-function cervical rehabilitation system and the control group, electroacupuncture alone.

BACKGROUND:Calcium phosphate has the similar mineral component of natural bones with good bioactivity, osteoconductivity and degradability. It has been widely used in bone defect repair and coatings of implants. OBJECTIVE:To review the major properties of different-phase calcium phosphate and to summarize the application of calcium phosphate in scaffolds for osteochondral tissue engineering. METHODS:A computer-based search of PubMed, CNKI and VIP database was performed for relevant articles published from January 2000 to February 2015 with the key words of “osteochondral; calcium phosphate (including hydroxyapatite, tricalcium phosphate, calcium polyphosphate); tissue engineering” in Chinese and English, respectively. RESULTS AND CONCLUSION:Since the calcium phosphate has a variety of phases and crystaline types, a variety of materials with different structure and size can be obtained using different techniques, such as hydroxyapatite, tricalcium phosphate, calcium polyphosphate, amorphous calcium phosphate. These materials have some differences in their biological and mechanical properties, and hydroxyapatite is the most widely used. Biocomposite scaffolds with calcium phosphates appeared to have promising potential in osteochondral tissue engineering.

As the core of mechanical experimental system of biologic tract tissue, the automatic measuring program of serial images based on measuring mark could provide two basic parameters for mechanical analysis, namely tissue length and average external diameter. Hybrid programming between VC+ + and Matlab is conducted. Subprogram will be in charge of the processing of single image (color-gray transform, image segmentation, pick-up target area according to measuring mark), while the main program written by VC+ + will orderly call the above subprogram again and again when it is traversing through the image sequence which records the process of a tissue's expansion and constriction under force, so the automatic measure of the serial images and mechanical analysis is achieved. The results showed: the experimental system could avoid the contrived errors caused by naked eye identification and manual choosing measuring area; the measuring precision could satisfy the need of tract tissue mechanical analysis; the system could save time and energy dramatically. The fact of tract tissue accords with the applicable conditions of mechanical analysis theory used in our experimentations.
