BACKGROUND: Family factor is the main reason for children's psychological and behavioral problems. Seen from the view of systemic family theory, in any circumstances, children's behavioral problems reflect various interpersonal systemic networks among society, school, family, relatives and friends and the relationship of complicated interactions among individuals.Family therapy is an important way to cure children's behavioral problems.OBJECTIVE: To observe whether systemic family rehabilitation is adequate for intervening in children's behavioral problems.DESIGN: Cluster sampling; Contrast observationSETTING: Department of Psychiatry, Kunming Medical College.PARTICIPANTS: A total of 276 students in grade four from Mingtong primary school of Kunming City were selected along with their parents from May 2004 to March 2005. A survey was conducted on students and their parents according to the principle of cluster sampling.METHODS: Self-rating family dynamics scale was used to investigate the characteristics of family dynamics of 276 students in grade four. Achenbach child behavior checklist for parents was adopted to investigate the situation of their children' s behaviors. 57 cases of children with behavioral problems were detected out, and took the families in which the whole family members voluntarily participated in the intervention as interventional group and the families in which any one of the family members did not want to participate in the intervention as abnormal control group. The students and their parents in interventional group were treated with 4-month systemic therapy. 4 months later, resent the above rating scales.MAIN OUTCOME MEASURES: Comparison of family dynamics and children's behaviors between interventional group and abnormal control group before and after intervention.RESULTS: After intervention, changes of family dynamics and children's behaviors in interventional group had taken place, which had statistical difference. The changes as follows: family atmosphere changed from "depressive and hostile" to "harmonious, pleasant, equal and exoteric"; the degree of individuation of family members changed from low level to high; disease concept changed from "regarding the patients as helpless victims" to "regarding them as helpful doers", which realize "softening of disease concept". The total scores of Achenbach child behavior checklist for parents decreased [The scores of questionnaire for fathers before and after intervention were (42.20±22.58) and (28.95±21.90) respectively, and scores of questionnaire for mothers before and after intervention were (50.95±14.60) and (36.40-±15.36) respectively, P ＜ 0.05]. There was no significant difference between the changes of children's behaviors assessed by fathers and mothers in abnormal control group [The scores of questionnaire for fathers before and after intervention were (38.32±17.30) and (37.57±16.45) respectively, and scores of questionnaire for mothers before and after intervention were (45.54±16.02) and (40.14±17.95) respectively, P ＞ 0.05].CONCLUSION: Using the idea and technique of systemic family therapy ,it is feasible and effective to intervene in children's behavioral problems by family therapy.

Objective To investigate the value of Doppl er tissue imaging (DTI) in detecting chronic ischemic myocardium before and after gene transfer. Methods An Ameroid constrictor was placed around the left circumflex artery of each open-chest pig. After 4 weeks, groupⅠandⅡwere intramyocardially administrated recombinant adenovirus coding for the vascular endothelial growth factors(Ad.VEGF-B) or phosphate buffer(PB). After 4 weeks, their hearts were removed for pathological investigation. Color M-mode, two-dimensional and spectrum DTI of lateral-posterior wall before operation, 2 weeks and 4 weeks after Ameroid placement, 2 weeks and 4 weeks after administration were studied. Results Color of normal myocardium was bright, filling and distinct stratified, and of ischemic myocardium faint, local lost and cloudy stratified. After gene transfer, color filling became better and stratification distinct. Normal V S of apical four chamber view (AP-4CV) was greater than that of left ventricular papillary muscle level short axis view (LVPM-SAM)(P

Objective To evaluate the safety of plasma volume replacement with HAES 130/0.4 during non-cardiac surgery in terms of hemodynamic stability, blood gases, hepato-renal function, blood coagulation and adverse reactions. Methods This was a five center prospective study comparing the safety and efficacy of HAES 130/0.4(6%) with HAES 200/0.5(6%)in a double-blind fashion. The selection criteria included ASA Ⅰ Ⅱ patients of both sex, aged 18-65yrs undergoing non-cardiac surgery of which the intraoperative blood loss was expected to exceed 400ml. Patients whose Hb

OBJECTIVE:A pharmacoeconomical analysis was performed to evaluate three therapeutic schemes for preventing post-appendectomy infections in children METHODS:The study included 119 children undergoing appendectomy According to the pathological results of appendix,they were divided into group Ⅰ and group Ⅱ,and treated with three different schemes respectively The schemes consisted of A:cefazolin+benzylpenicillin+metronidazole,B:cefotaxime+benzylpenicillin+metronidazole and C:cefazolin+benzylpenicillin+metronidazole+claforan These three schemes were assessed with pharmacoeconomic evaluation RESULTS:As for group Ⅰ,scheme A and B were better than scheme C As for group Ⅱ,scheme A was the best CONCLUSION:Application of pharmacoeconomics will optimize therapeutic scheme and guide rational use of drugs

Objective: To investigate the mechanism and correlative factors of SAM syndrome after aortic valve replacement. Methods: 48 patients with severe aortic valve stenosis were studied, echo-Doppler study was performed one week after aortic valve replacement, and the patients were divided into two groups with or without SAM Syndrome. The left ventricular end-diastolic dimensions, the left ventricular end-Systolic dimensions, the left ventricular outflow tract the thickness of septum and posterior wall, the maximal left ventricular velocities and left intra-ventricular dynamic gradients were recorded and compared. Results: There was no operative mortality. The maximal left ventricular velocities were increased significantly in 9 patients (more than 2。5 m/s) and six of them had SAM syndrome. There were statistic significance (P

Objective To investigate the effect of cosmetic surgery on the facial soft tissue injuries.Methods The clinical data of 52 patients with facial soft tissue injuries from June 2013 to June 2014 were analyzed retrospectively.And plastic surgical techniques were applied to the early treatment of facial soft tissue injuries in patients,according to the size of defect and the degree of deformity of the patients,different plastic surgery treatment was chosen,such as skin flap or skin graft to repair wound surfaces.In this process,one must follow sterile noninvasive principle strictly with emphasis on the technique of plastic surgery such as entire debridement,wound healing application of skin flap and so on.Results Total 49 cases of facial soft tissue injuries were healed by first intention without significant complications,while 4 cases of them had mild scars.Absorbable suture exposition appeared in 3 patients after primary healing.Those sutures were romoved after disinfected and no sequelaes were happened.All patients were recovered with good appearances and functions to the most exent.Conclusions The treatment of facial soft tissue injuries,by applying plastic and aesthetic surgery,could reduce scar and postoperative deformity,and secondary corrective procedures can be avoided in most patients.

Objective:To analyze the clinicopathological characteristics, diagnosis, and differential diagnosis of hepatic perivascu-lar epithelioid cell neoplasm (PEComa). Methods:The clinicopathological features of seven hepatic PEComa patients treated in Shanxi Cancer Hospital from March 2008 to March 2015 were studied with light microscopy and immunohistochemistry combined with litera-ture review. Results:The age range of the seven patients was 41-56 years old (median:51.5 years old). Two were males and five were females. Their histopathological subtypes were classic type (2/7), smooth muscle type (3/7), and fat type (2/7), respectively. Immunohis-tochemical study showed that HMB45 was positive in 7 cases, SMA and VIM were expressed in 6 cases, Melan A was positive in 5 cas-es, and Desmin was expressed in 2 cases. In addition, the mean proliferative index was 1.3%(range:0%-5%), and TFE3 was negative in all cases. Conclusion:Hepatic PEComa is a rare primary liver tumor. The diagnosis and treatment of this disease should be intensi-fied, and long-term close follow-up is necessary. Positive result for HMB45, Melan A, and SMA are the key features of PEComa.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.
