Objective To study the effects of body weight status in school-age children on later development of physcial growth , physcial growth ,and blood pressure .Methods Physical examination records of schoolchildren completed in 2005 and in 2009 in one district of Chongqing was used by information matching to identify the same person in two examinations .The body weight in former examination was grouped according to the national reference of weight by age ;the effects of this body weight level on the changes of weight ,height ,and blood pressure between two examinations were analyzed .Results There were 10 373 subjects aged from 6-14 years old were linked between two examinations .Results showed that in younger children underweight was associated with a higher increasments of weight and height .The increment of blood pressure was negatively associated with weight in younger children but this relationship disappeared or reversed in older children .The increment of blood pressure was also positively associated with the weight gain in all children ,no effects of height gain on blood pressure was founded .Conclusion Underweight usually has a catch up development of weight and hieght before puberty ,underweight in younger school age ,more weight gain and overweight in older school age mihgt be the risk factors of hypertension .

Objective To explore the clinical significance of the changes of interleukin-6(IL-6) contents in serum and urine in children with primary nephrotic syndrome(PNS).Methods The contents of IL-6 in serum and urine in 38 cases of PNS were exa-(mined) by ELISA before and after treatment with prednisone 2 mg/(kg?d) for 8 weeks.Results Before the treatment with prednisone,the contents of IL-6 in serum in steroid-responsive group and steroid-resistant group were significantly higher than those in the normal controls(P0.05).In the steroid-responsive group and steroid-resistant group,the levels of IL-6 in urine were significantly higher than those in the normal controls(P0.05).The contents of IL-6 in steroid-resistant group in serum and urine had significant difference in the comparison with the normal controls(P

Long-term endurance training or physical activity has been confirmed not only to improve physical performance, but to bring about an obvious beneficial effect on human health; however, the mechanism of this effect is not clear. The most studied health adaptations in skeletal muscle response to endurance exercise are increased muscle glycogen level and insulin sensitivity, fiber type transformation toward oxidative myofibers, and increased mitochondrial content/function. Mitochondria are dynamic organelles in eukaryotic cells critical in physical performance and disease occurrence. The mitochondrial life cycle spans biogenesis, maintenance, and clearance. Exercise training may promote each of these processes and confer positive impacts on skeletal muscle contractile and metabolic functions. This review focused on the regulation of these processes by endurance exercise and discussed its potential benefits in health and disease. We presented evidence suggesting that exercise training potentiates not only the biogenesis of mitochondria but also the removal of old and unhealthy mitochondria through mitochondrial quality control.

The genus Myristica (Myristicaceae) consists of 120 species, which were distributed in South Asia, from west Polynesia, Oceania, eastern India to the Philippines. Phytochemical studies showed that 164 compounds including a majority of lignans, along with phenglpropanoids, flavonoids and phenolics, have been isolated from this genus, which exhibited anti-microbial, anti-inflammatory, anticancer, hyperglycemic and hepatic protective activities. This article summarizes research progress of the chemical compositions and their pharmacological activities from this genus, which could provide reference for the in-depth development and utilization of the Myristica plants.

According to the existing Provisions for Drug Registration (SFDA Order No. 28), applications for new drugs of traditional Chinese medicine are divided into two parts: the applications for drug clinical trial and for drug production (including new drug certificate). It will last for about 10 years from the application for drug clinical trial to get approving, and it also remains many problems and the low probability to succeed. From the sight of pharmaceutical review, there are mainly two aspects of regulatory compliance and technical issues, mainly for changes without approval of the competent authorities of the country. For example, sample preparation and approval of clinical trial process are significant changes. Technical problems are reporting incomplete data or information submitted does not comply with the technical requirements for review, such as: production process validation does not provide information, the preparation of samples for clinical trials and field inspection, production information, or the information provided does not meet the technical requirements. This paper summarizes the frequently asked questions and to make recommendations to advise applicants concerned, timely detection of problems, avoid risk, improving the quality and efficiency of the application for registration.

BACKGROUND: Primate is the best animal to establish a model of spinal implants. However, ethics and cost limit its application. Mixed-breed dogs have similar anatomic structures as human. Moreover, it is easy to obtain with low cost, so it may replace primate to serve as models.OBJECTIVE: To determine the feasibility of canine lumbar spine to establish the anterior interfixation model following measurements of related anatomic data.METHODS: A total of 9 adult healthy dogs were selected. The transversal diameter, sagittal diameter and height of vertebral body and disc were measured, and the artificial vertebral body replacement was performed. Bone graft fusion was observed. RESULTS AND CONCLUSION: The transversal diameter, sagittal diameter and height of vertebral body and disc increasedgradually from L_(1) to L_(7), and the height was greatly exceeded its sagittal diameter. All dogs survived, but one was paraplegia. Allthe others stood and acted in 12 h to 72 h after operation. The fusion effect was proved to be good by imageology and histology. The establishment of models was simple and cost-effective, and the biocompatibility of bone tissues and implants, as well as thebone tissue ingrowth can be observed. The lumbar spine of dog can be used as an anterior interfixation model in vitro test.
