In the medical theory and operation, the classic Morita therapy has been permeated with the medical concept of bio-psycho-social medical model. However, over the past century, the research on Morita therapy has been gradually affected by the biomedical model, which has greatly affected the inheritance and development of Morita therapy. It is imperative to further explore the essence of Morita therapy from the perspective of bio-psycho-social medical model and innovate its theory and operation. Therefore, on the basis of classical Morita therapy, the author actively advocate the changes of diagnosis and treatment thinking and behavior, and carry out the research and practice of Chinese Morita therapy, the new understanding of the theory of " feeling of illness" , the new explanation of " let it be" , psychotherapy for nervousness induced illness perception, psychotherapy of modified coping style and psychological balance therapy are put forward. It further reflects the scientificity of Morita therapy in the process of disease diagnosis and treatment under the bio-psycho-social medical model.

Objective:To study the relationship between graduate students'personalities, life events and psychic symptom.Methods:828 graduate students in Tianjin were investigated, their psychosomatic symptoms were rated with SCL-90 and psychosocial factors were assessed with Cattell 16 Personality Factors Questionnaire and Life Event Scale.Result:The first three factors in the psychosomatic symptoms were displayed in order: Obsession-compulsion(0.67?0.55), Interpersonal sensitivity (0.61?0.56), and Depression(0.50?0.51).The personalities were revealed as follows: E (6.23?1.69) , F(6.23?1.80) and Q 4(6.12?1.10), these factors were higher than Chinese norm, L (3.82?1.62), O (4.64?1.70) and I (4.86?1.62) were lower than norm.Conclusion:Male, having siblings, engineer and negative scores of work and study are risk factors for psychosomatic symptoms, whereas medical staff is a protective one.

BACKGROUND:Constant magnetic field of proper intensity can inhibit the proliferation of vascular smooth muscle cells,and it can be used to inhibit the restenosis following percutaneous coronary intervention.OBJECTIVE: To observe the effect of constant magnetic field of different intensities on the expression of osteopontin gene in rat aorta smooth muscle cells, so as to investigate whether magnetic field can be used to prevent and treat restenosis following percutaneous coronary intervention.DESIGN: A randomly grouping and controlled observation.SETTING: Department of Cardiology, Xijing Hospital of the Fourth Military Medical University of Chinese PLA.MATERIALS: The experiments were carried out in the laboratory of Department of Cardiology (Military Institute of Cardiovascular Disease), Xijing Hospital of the Fourth Military Medical University of Chinese PLA from February to December in 2006. Male pure SD rats of 200-250 g were used.METHODS : Rat aorta smooth muscle cells were cultured in vitro in DMEM medium containing fetal bovine serum (0.1 in volume serum), and then the cells were randomly divided into control group, constant magnetic field of 1, 5, 10 and 50 Gs groups, those in the control group were not treated with magnetic field, and those in the other groups were treated with magnetic field and cultured for another 48 hours. Reverse transcription-polymerase chain reaction and Western blotting were combined with absorbance (A) scanning analysis to observe the effect of constant magnetic field on the expressions of osteopontin and its mRNA in smooth muscle cells.MAIN OUTCOME MEASURES: Expressions of osteopontin and its mRNA in smooth muscle cells.RESULTS: The expressions of osteopontin and osteopontin genes in the constant magnetic field groups were significantly decreased as compared with that in the control group (P ＜ 0.05), there were also significant differences among the constant magnetic field groups of different intensities (P ＜ 0.05). It was indicated that the stimulation of constant magnetic field was in an intensity-dependent manner, and the expressions of osteopontin and osteopontin mRNA were enhanced as the intensity of magnetic field was increased.CONCLUSION: Constant magnetic field of proper intensity can inhibit the osteopontin expression in vascular smooth muscle cells on the gene level, and magnetic field may play a role in preventing and treating the restenosis following percutaneous coronary intervention.

Objective Investigate the effects of early application of noninvasive respiratory support on very low birth weight infant(VLBWI). Method A total of 65 VLBWI(born during September 2015 to September 2016 with 28-32 weeks gestational age;1000 g ≤ birth weight < 1500 g;exclusion of combination with congenital deformity)were randomly divided into the early application of noninvasive respiratory support as observation group (n = 33) and the application of endotracheal intubation with gen respiratory support as control group (n = 32). Comparison of two groups was carried out by SPSS in terms of incidence of endotracheal intubation,BPD,pulmonary infection,pneumothorax,and necrotizing enterocolitis,together with rescue ratio,total oxygenation time and hospitalization. Results No significant difference was found on incidence of pneumothorax,necrotizing enterocolitis and rescue ratio between two groups. The incidence of endotracheal intubation,BPD,pulmonary infection and total oxygenation time was markly decreased in observation group. Conclusion Early application of noninvasive respiratory support benefits VLBWI via reducing incidence of endotracheal intubation,BPD,pulmonary infection, total oxygenation time.

Objective To explore effects of Naikan cognitive therapy on improving clinical symptoms in patients with convalescent schizophrenia. Methods The 69 convalescent schizophrenic patients with convalescent clinical state were consecutively recruited. All the patients were divided into Naikan cognitive therapy ( NCT) group an control group at random and were pretreated with antipsychotic agent therapy. In NCT group,the patients received NCT for successive 7 days. In control group,the patients only received antipsychotic agent therapy. Pre-and post-treatment positive and negative syndrome scale( PANSS) , Nurses'observation scale for inpatient evaluation (NOSIE) were administered to all subjects. Results ① A significant decrease occurred in PANSS total score, negative symptom score, positive symptom score, compound scale score, general psychopathology score, reaction retardation score and paranoid score in NCT group ( t = 2. 672～7. 370, P < 0. 05). In the post-treatment, PANSS total score, negative symptom score, positive symptom score, compound scale score, reaction retardation score and thought disorder score were significantly lower in NCT group than those in control group ( t ' = 2. 696, P = 0. 009; t = 5. 186, P=0.000; t = 3.757, P = 0.001; t = 2.634,P = 0.011; t ' =2.376, P = 0.021). ②A significant decrease occurred in NOSIE total negative score( 10.43 ± 9. 24 vs 13. 87 ± 8. 03, t = 3. 463 , P = 0. 002) , irritation score(3. 13 ±0.43 vs8.53 ±4.98, t = 6. 139, P=0.000) and retardation score(1.07 ± 1.64 vs 2. 20 ±2.85, t = 2.067, P = 0.048) in NCT group. Conclusion NCT can possibly improve part clinical symptoms of patients with convalescent schizophrenia to a certain extent,especially negative symptom,but need to further prove the effect of NaiKan cognitive therapy.

Objective To investigate the role of Ephrin A2 in the regeneration and reinnervation of hair cells in the chick cochlea following kanamycin ototoxicity.Methods 66 newly hatched Roman chickens (3 days old) were randomly divided into experimental group and control groups. Experimental chickens (n=48) received intramuscular kanamycin (200 mg/kg:Sigma,St Louis,MO) for 10 consecutive days and were subsequently sacrificed 2 days before the last injection,and 1,3,7,10,15,21,30,and 60 days after the last injection (n=6 per subgroup). Control chickens (n=18) were untreated and sacrificed 3,13 and 43 days after hatching (n=6 per subgroup). Ephrin A2 protein expression in acoustic ganglia was determined by western blot analysis in all chickens after sacrifice. Results Ephrin A2 protein expression was found and the protein level was almost same in acoustical ganglia of all normal chickens. After kanamycin exposure,the Ephrin A2 protein expression level in the cochlea of the experiment chickens from 2 to 7 days after last kanamycin injection was lower than that in control chickens,respectively. Ephrin A2 expression increased obviously at 15 days after kanamycin last injection. By 30 days after the cessation of kanamycin treatment,the level of Ephrin A2 protein approximated to that in normal control group.Conclusion The expression of Ephrin A2 protein in the acoustical ganglia basically synchronizes with the regeneration and the reinnervation of the hair cells in the chicken cochlea following kanamycin damage,indicating that Ephrin A2 may play an important role in this process.
