Chinese Journal of Behavioral Medicine and Brain Science 2011;20(12):1115-1117
Objective To investigate the role of psychological intervention on cosmetic plastic surgery.Methods 600 cosmetic plastic surgery were collected from cosmetic plastic surgery of Jinan Military General Hospital,then randomly divided into control group(n=300) and study group (n=300) according to odd and even on the first visit.Conventional treatmentand care were applied to control group before,during and after operation.For study group,in addition to giving a general treatment and care,preoperative consultation talks were given to understand the beauty of the psychological characteristics,and motivations and expectations were given to adjust;music and psychological support were presented intraoperative; rehabilitation guidance were given after operation.Symptom checklist 90( SCL-90),general psychological problems of body image self-rating scale and postoperative satisfaction scale were used to assess the the mental state,body image question and satisfaction of plastic surgery.Results Before intervention,the scores of SCL-90 and the general body image self-rating scale were ( 187.5 ±52.61 ),(12.1 ± 2.2) in study group and (179.87 ± 53.33 ),(12.9 ± 2.0) in control group,there was no significant differences(P>0.05).After intervention,the scores of SCL-90 and the general body image self-rating scale ( 159.6 ± 31.3 ),(5.6 ± 0.5 ) in study group were lower than those in control group ( 167.4 ± 38.2 ),( 6.2 ±1.1 )(P < 0.01 ).Before and after treatment,50% reduced rate of 26%,25% reduced rate of 41.6%,body-negative rate of 97.1%,overall satisfaction rate of 89% of surgery in study group were higher than 14%,27.6%,84.3% and 53.67% in the control group,the differences were significant (P<0.01 ).Conclusion Psychological interventions can improve the psychological state,body image disturbance and operative satisfaction in cosmetic plastic surgery.Psychological interventions should pay more attention to irrmprove the efficacy of cosmetic plastic surgery.

BACKGROUND:Currently, transplantation of bone marrow mesenchymal stem cel s into the spinal cord is very limited to the recovery of animals fol owing spinal cord injury. Methylcobalamin is a common drug for the treatment of neurological diseases and injuries, but its effects on bone marrow mesenchymal stem cel s are unclear. OBJECTIVE:To study the feasibility of bone marrow mesenchymal stem cel s differentiating into neuron-like cel s induced by methylcobalamin in vitro and to observe the cel viability and proliferation of differentiated cel s. Methods:Rat bone marrow mesenchymal stem cel s were isolated, cultured and purified by density gradient centrifugation and adherent culture. The fourth to fifth generation of bone marrow mesenchymal stem cel s were treated for 24, 48 and 72 hours with different concentrations (25, 50 and 100 mg/L) of methylcobalamin. The morphological changes and cel growth were continuously observed under an inverted phase constract microscope. The viability of induced cel s was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The expressions of Nestin and neuron-specific enolase were identified by reverse transcription PCR and western blot. RESULTS AND CONCLUSION:Most of bone marrow mesenchymal stem cel s could differentiate into neuron-like cel s after induction with methylcobalamin. The expressions of Nestin and neuron-specific enolase were up-regulated after 48 hours of methylcobalamin treatment at different concentrations, especial y after treatment with 100 mg/L methylcobalamin. Similarly, the expressions of Nestin and neuron-specific enolase could be increased significantly after 100 mg/L methylcobalamin treatment for 24, 48 and 72 hours, especial y for 72 hours. It is indicated that methylcobalamin can induce bone marrow mesenchymal stem cel s differentiating into neuron-like cel s, and the optimal concentration of methylcobalamin is 100 mg/L.

Objective To evaluate the results of the treatment and prevention measures for pathological dislocation of the hip following septic arthritis in the newborns. Methods Twenty cases undergone open reduction were studied restropectively. In addition, greater trochanterplasty was penformed in 15 cases, acetabularplasty in 14 cases, greater and lesser trochanterplasty in 2 cases. Rusults A successful rate of reduction achieved in 90% of the patients; however, central reduction was achieved in only 38.8% . 20 patients were followed-up for 6 months to 12 years. The stability and motility of the hip gradually improved in majority of the patients. The cases with severe destruction followed by absence of femoral head and neck had unsatisfactory results. Shortening deformity were found in six cases, and subluxation, dislocation, rigidity of the hip in one case each. Conclusion The greater trochanterplasty had a good result for reduction and maintaining the position. Early diagnosis and early open drainage were key measures for prevention of pathological dislocation of the hip resulting from the acute septic arthritis in the newborn.

Immobilization osteoporosis (IOP)is a common complication in clinic and cosmonauts. It severely impaired the patients ant the cosmonauts. The causes of IOP are weightless,immoblization and bed rest.Excercise therapy is very important for IOP. The etiology andpathogenesis of IOP are introduced in this article. the effects, mechanism and methods of the exercise therapy for preventing and treating IOP arealso discussed.

Objective To reasonably confirm the target of 3-dimensional conformal radiation therapy (3DCRT) for lung cancer. Methods While a patient was breathing, the motion of the primary lesion in the lung was observed by fluoroscopy. The extent of motion of the primary lesion during irradiation was evaluated by portal films. Three 3DCRT plannings for lung cancer, in which gross tumor volume (GTV) decided by a group of radiation oncologists and implemented, were taken as the standard. The GTV delineated by five radiation oncologits was compared with the standard by computing the radial line measurement variation (RLMV). Results From fluoroscopic observation in fifty-nine patients, the extent of lesion motion was the largest in cephalo-caudal direction, with 14.3 mm for lesions in the lower and 7.1 mm (median) for middle part of the lung. In lateral and antero-posterior directions, it was within 4. 0 mm. The motion error during irradiation was 4. 2 mm in lateral direction and 4.6 mm in cephalo-caudal direction. The random error, system error and total error for set-up uncertainty were 3.4 mm, 6.0 mm, and 6.9 mm. Compared to the standard, the discrepancy of GTV could be as large as 150% . The largest RLMV was observed in the area of lung hilar nodes. Conclusions The target of 3-dimensional conformal radiation therapy for lung cancer should be confirmed individually and delineated by a group of radiation oncologists. A more efficient fixing device is needed owing to the large total error for set-up.

AIM: To study the decomposition reaction kinetics of aqueous salvianolic acid B(Sal B). METHODS: HPLC was applied to determine Sal B's content of samples.Relationship between Sal B's content and heating time was regressed. RESULTS: Decomposition reaction of Sal B's aqueous solution was first order reaction.The effect of temperature on reaction rate of Sal B's decomposition was higher than pH value.At lower temperature(50℃),reaction rate constant K of Sal B's decomposition was very low and it changed very little with pH values. CONCLUSION: Water extraction process of Salvia Militiorrhiza should avoid applying high temperature,alkaline condition and long heating time in order to reduce loss and decomposition of Sal B,and then also increase Sal(B's) content in the extract.
