BACKGROUND:Osseous deformity is one of the most common Jaw deformities in clinic, which give patients serious impact on functionality and aesthetics, so patients want to cure it strongly. Recently, Functional Magnetic System has played an increasingly important role in correcting osseous deformity because of its advantages, so it is gradual y known by people.
OBJECTIVE:This article wil give a summary of Functional Magnetic System in the progress and deficiencies, in order to have a greater development in the field of correct osseous deformity.
METHODS:We searched the PubMed database, from January 1990 to June 2013 with the key words of“magnetic, orthodontics”in English. An online search of CNKI database, Wanfang database, Chongqing VIP database from January 1990 to June 2013 was also conducted with the key words of“magnetic, orthodontics”in Chinese.
RESULTS AND CONCLUSION:Functional Magnetic System is the combination of magnetic force and the traditional function correcting device, with the aid of attraction and repulsion, we could make up for the inadequacy in the treatment of Jaw osseous deformity, including the problems of length, width and height. With the development of magnetic materials and the research of magnetic materials, Functional Magnetic System wil have a bigger development.

[Objective] To investigate the effects of the Sheng Jing Tang, one of tonyfing kidney and promoting blood circulation recipes,on female rats anovulatory due to testosterone and to study the mechanism of action of the recipe. [Methods] The rat models of anovulatory disease were established by injecting the immature female SD rat with testosterone and treated with TCM and herbs to observe estrous cycle level of sex hormone of blood and the change of pathological histology of ovary. [Results] Sheng Jing Tang could improve the level of sex hormone, contract the expanded oxarian vesicles obviously and increase the quantity of luteum. [Conclusions] Sheng Jing Tang had the effect of improving the syndromes of Polycystic Ovary, inducing ovulation and recovering the function of ovary.

Objective To explore the effect and utilization of comprehensive treatment on intrahepatic recurrence after hepatic resection for hepatocellular carcinoma.Methods One and two year recurrent rate of 60 patients with hepatocellular carcinoma who underwent hepatic resection in a two-year follow up were analyzed retrospectively,control group 30 cases,comprehensive treatment group 30 cases.Results One and two year intrahepatic recurrent rate of comprehensive treatment is 13％(4/30)and 40％(12/30)respectively.The difference was statistically singnificant(x2=4.176,4.310,all P＜0.05).Conclusion The effect of comprehensive treatment on postponing intrahepatic recurrence after hepatic resection for hepatocellular carcinoma is obvious.

In China, fall ranks the top 3 among adverse events in hospital and it is the first cause of death in the elderly aged 65 and above. Fall risk factors and characteristics, nursing assessment and nursing care interventions are reviewed in this paper to explore risk factors and further improve the nursing care interventions for falls in hospitalized elderly patients.

BACKGROUND: Imported self-locking brackets cost much. So it is necessary to develop low-cost and easy-to-operate domestic self-locking brackets.OBJECTIVE: To introduce a newly developed self-locking brackets, and investigate the frictional forces of the brackets. DESIGN, TIME AND SETTING: Biomechanical controlled analysis was performed in the Laboratory of Harbin Medical University in January 2004. MATERIALS: Self-made self-locking brackets and domestic conventional tie-wing stainless steel brackets; domestic Ni-Ti round wire, Australian stainless steel round wire, and domestic stainless steel rectangular wire. METHODS: Two kinds of brackets were combined with three kinds of arch wires. Under the drive of micromotor, pull sensor moved at 1 mm/min. An arch wire, which was ligated in the bracket, was dragged. Thus, teeth's shift was imitated.MAIN OUTCOME MEASURES: Waveshape was observed through the use of storage oscillograph and corresponding data were recorded. Frictional force was determined and compared.RESULTS: Under the same other conditions, no matter which kind of arch wires were combined with, tie-wing brackets produced greater frictional force than self-locking brackets (P < 0.001). Under the same other conditions, no matter which kind of brackets were combined with, Ni-Ti wire produced greater frictional force than Australian stainless steel round wire and domestic stainless steel rectangular wire (P < 0.001). In addition, domestic stainless steel rectangular wires produced greater frictional force than Australian stainless steel round wires (P < 0.001). CONCLUSION: Self-locking bracket produces low frictional force, so it is fit for orthodontic doctors to use the corrective force.

Objective:Discussion MKK4 protein expression in nasopharyngeal carcinoma and -1044 A/T polymorphism correlation.Methods:90 patients with nasopharyngeal carcinoma , MKK4 protein expression was determined by immunohistochemical staining,polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP ) to detect the gene -1044A/T sites monocytes nucleotide polymorphism.Results:MKK4 protein expression in nasopharyngeal carcinoma (-) was 24.4%(22/90),(+) was 15.6%(14/90),(++) was 34.4%(31/90),(+++) was 25.6% (23/90).Low expression (-/+) patients with a total of 36 cases,-1044AA genotype accounted for 22 cases (61.11%),AT genotype accounted for 12 cases (33.33%),TT genotype accounted for two cases (5.56%),AT+TT gene type accounted for 14 cases (38.89%).The patients with high MKK4 expression of 54 cases,of which accounted for 38 cases of AA genotype (70.37%),AT genotype accounted with 15 cases (27.78%),TT genotype accounted for one case (1.85%),AT +TT genotype accounted for 16 cases (29.63%).Low expression and high expression of T gene mutation occurs no significant ( Z=0.323 , P=0.747 ) .Conclusion: MKK4 protein expression correlated with -1044 A/T gene promoter polymorphisms was no significant correlation .

BACKGROUND:A new open“C”-shaped molar band with nanocoating (patent number:ZL201110057699.1) has been invented to overcome some weakness of traditional bands and buccal tubes, which is used for molar fixation. OBJECTIVE:Using three-dimension finite element analysis software to theoretical y prove that the new band comes up to clinic requirement. METHODS:We established a finite element model of alveolar bone-tooth-band, and node domains tensile and shear loading were given. Stress distribution of the new bands through numerical simulation was predicted and calculated. Simulation of 20 N orthodontic force was applied in medial direction, distal direction and vertical direction in the three-dimensional model of a new band buccal tube and traditional band, to analyze the stress state in different directions under the force of the binder. RESULTS AND CONCLUSION:By numerical simulation of three-dimensional finite element, the stress of the new band was higher than that of the traditional band, but it could not reach the clinical cracking limit of resin reinforced glass ionomer cement. So the new band could theoretical y satisfy the clinical requirements.
