Objective To investigate the effects of antioxidant on the gene expression of ?1-adrenergic receptors (AR) during endotoxic shock. Methods Forty male SD rats weighing 200-250 g were anesthetized with intraperitoneal (i.p.) pentobarbital. The animals kept spontaneous breathing. Femoral artery and vein were cannulated for BP monitoring and drug administration. The animals were randomly divided into 5 groups ( n = 8 each) : (1) control group; (2) LPS group received IPS 15 mg?kg-1 i.v. ; (3) LPS + propofol group received at 1h after LPS a bolus of propofol 10mg?kg-1 i.v. followed by continuous infusion of propofol at 10 mg?kg-1?h-1; (4) LPS + uric acid (UA) group received uric acid 200 mg i.p. 1 h after LPS and (5) LPS + melatonin (MLT) group received MLT 10 mg?kg-1 i.p. 1h after LPS. The animals were killed at 6 h after LPS. Total RNA was extracted from the heart, aorta, vein, lung, liver and kidney. ?1A-,?1B-,?1D- AR mRNA and ?-actin mRNA were measured using reverse transcription polymerase chain reaction (RT-PCR) .Results The expression of ?1A-AR and ?1B-AR mRNA in all the organs and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were strongly down-regulated in LPS group. In group 3 (LPS + propofol) the expression of ?1A-AR mRNA in the lung and kidney, the ?1B-AR mRNA expression in all of the organs and ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly increased as compared with LPS group. There was no significant difference in ?1-AR mRNA expression between LPS group and LPS + MLT group. The expression of ?1A-AR mRNA in kidney, the ?1B-AR mRNA expression in all of the organs except the lung and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly higher in LPS + UA group than in LPS group. Conclusion Circulatory failure induced by endotoxic shock is related to the down-regulation of ?1-AR gene expression. The therapeutic effects of antioxidant on the endotoxic shock is partly due to up-regulation of ?1-AR gene expression.

Objective To study the effects of self- edited doggerel on health education of senile AIDS patients in northern Guangxi region, in order to seek a suitable and effective way for the senile AIDS patients' health education. Methods 200 senile patients who were inpatients in dermatological department and examinees in the center of health examination of our hospital were randomly divided into the experimental group and the control group from August to December in 2009, 100 cases in each group, the experimental group was educated by a method of adopting a self-edited doggerel, the control group was educated by traditional way including manual + video or a series of special lectures, Two groups were carried out questionnaire survey designed by ourselves before and after the education during a period of a week and then evaluated the effects of health education. Results Compared with the rate before adopting self-edited doggerel, the knowing rate of AIDS and regulations of the experimental group was above 90%,there was a significant increase; and compared with the control group, the rate was also higher than the latter. The behaviors and attitudes of the experimental group had a significant positive improvement, but showed no significant difference between the two groups. Conclusions The doggerel is humorous, rhyming, simple and easy-going, it is so user-friendly, easy to understand and to remember that it is a suitable and effective way for the health education of senile AIDS patients.

Objective To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) combined with eye-acupuncture on cognitive dysfunction on cognitive dysfunction in patients with traumatic brain injury. Methods From May, 2014 to June, 2016, 90 trau-matic brain injury patients with cognitive impairment were randomly divided into eye-acupuncture group (n=30), rTMS group (n=30) and combination group (n=30), who accepted eye-acupuncture, rTMS and combination of eye-acupuncture and rTMS, repectively, for eight weeks. They were assessed with Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) before and after treatment. Results There was no significant difference in scores of LOTCA among three groups before treatment (F<0.523, P>0.05). The scores of LOTCA were the best in the combination group after treatment (F>3.789, P<0.05). Conclusion The combination of eye-acupuncture and rTMS is more effective in improving cognitive function after traumatic brain injury than either alone.

BACKGROUND: Previous researches indicate that ADp14ARF transfecting positive tumor cell line of p53 can inhibit the proliferation; in addition, the inhibitory effect is superior to transfection negative tumor cell line of p53. Whether simultaneous transfection of p14ARF and p53 genes can increase expression and accumulation of p53 and accelerate apoptosis of tumor cells needs further studies.OBJECTIVE: To construct double plasmid expression vector plRES-p14ARF-p53 by using gene engineering so as to observe the inhibitory effect on proliferation of osteogenic sarcoma cells.DESIGN: Randomized controlled observation.SETTING: Department of Orthopaedics, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Public Laboratory Platform, Immune Researching Room, Basic Medical College, Tongji Medical College, Huazhong University of Science and Technology from January 2005 to October 2006. Human osteogenic sarcoma MG-63 cells were provided by Cell Laboratory, Immune Researching Room, Tongji Medical College, Huazhong University of Science and Technology. plRES-p53 plasmid and plRES vector containing p53total-length gene order were provided by Wuhan Jingsai Biology Company.METHODS: Based on gene engineering, p14DNA (0.5 kb) was amplified from cultured L02 cells of normal human hepatic cells into plRES vector. Recombinant plasmid plRES-p14ARF-p53 was determined with polymerase chain reaction (PCR) and restriction enzyme and transfected into human osteogenic sarcoma MG-63 cells through mediation of liposome to screen positive clones. Otherwise, cells were divided into three groups, including blank control group (MG-63cells), blank vector control group (stably transfecting plRES-neo cells) and p14ARF-p53 group (stably transfecting plRES-p14ARF-p53 cells). ① DNA content and cycle of tumor cells were measured by using flow cytometry before and after transfection. ② Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect quantitative and semi-quantitative expression of p53 and p14ARF protein in tumor cells after stable transfection. ③Thiazole blue chromatometry and growth curve were used to observe proliferation.MAIN OUTCOME MEASURES: ① DNA content and cycle of osteogenic sarcoma cells; ② expressions of p53 and p14ARF protein in tumor cells; ③ proliferation.RESULTS: Double plasmid expression vector plRES-p14ARF-p53 was constructed successfully. ① DNA content and cycle of osteogenic sarcoma cells: Flow cytometry demonstrated that tumor cells mainly stayed in G1 phase after transfection. ② Protein expression: RT-PCR and Western blot indicated that p14ARF and p53 gene independently expressed in target cell mRNA and protein, respectively. ③ Cell growth: At 24, 48, 72 and 96 hours after MG-63 transfection, inhibitory rates of tumor cells were 33.43%, 69.37%, 66.19% and 75.26%, respectively, which was significant difference as compared with blank vector control group (P ＜ 0.01).CONCLUSION: Wild p53 and p14ARF can synergistically inhibit the proliferation and accelerate the apoptosis of osteogenic sarcoma cells.

Objective To assess and delineate the dosimetric shortcomings of conventional radiotherapy planning,as compared with the three dimensional treatment planning system, and to obtain a better technique in the treatment of lung cancers.Methods Thirteen patients with stage ⅢA ⅢB non small cell lung cancer were chosen in the present study. Using the Cadplan 6.0.8 treatment planning system , three different methods of radiotherapy planning: conventional planning, conventional and conformal planning, and conformal planning were designed for each patient. The total radiation dose was 66 ?Gy and DVHs were used to assess the dosimetric distribution in the gross tumor volume and the surrounding organs at risk. Results No significant dosimetric disparity in the target volume was found among the three designs, according to anticipated therapeatic requirements. The conformity indices were 0.13,0.24 and 0.35 for these three radiotherapy designs. The mean lung volumes which received radiation dose of≥20?Gy were 32%,26% and 25%.The mean maximum dose at the spinal cord were 42?Gy,49?Gy and 33?Gy.The mean esophageal volume which received radiation of ≥50?Gy were 32%,34% and 22%, and the mean radiation dose to the heart were 18?Gy,15?Gy and 12?Gy,respectively. Conclusions Conventional radiotherapy planning is able to meet the demands of dosimetric requirements for radiation treatment of lung cancers. The three dimensional conformal radiation therapy planning system is able to provide superior delivery of high dose to the target volume without inflicting too high a risk to the surrounding normal tissues and organs.

Objective On basis of physical dose optimization, LQ model was used to investigate the difference between the curves of biological effective dose and physical isodose. The influence of applying the biological dose concept on three dimensional conformal radiotherapy of prostate carcinoma was discussed. Methods Four treatment plannings were designed for physical dose optimization: three fields, four-box fields, five fields and six fields. Target dose uniformity and protection of the critical tissue -rectum were used as the principal standard for designing the treatment planning. Biological effective dose (BED) was calculated by LQ model. The difference between the BED curve drawn in the central layer and the physical isodose curve was studied. The difference between the adjusted physical dose (APD) and the physical dose was also studied. Results Five field planning was the best in target dose uniformity and protection of the critical tissue -rectum. The physical dose was uniform in the target, but the biological effective doses revealed great discrepancy in the biological model. Adjusted physical dose distribution also displayed larger discrepancy than the physical dose unadjusted. Conclusions Intensified Modulated Radiotherapy (IMRT) technique with inversion planning using biological dose concept may be much more advantageous to reach a high tumor control probability and low normal tissue complication probability.

Objective To observe any effect when eye acupuncture is combined with computer-assisted cognition training to ameliorate cognitive dysfunction after stroke.Methods Stroke patients with cognitive impairment were randomly divided into an eye acupuncture group (n=30),a computer group (n=30) and a combination group (n=30).The eye acupuncture group was given eye acupuncture,the computer group was given rehabilitative cognition training with specialized equipment and the combination group was given both eye acupuncture and the computeraided training.The treatment lasted 2 months.The Loewenstein occupational therapy cognitive asessment (LOTCA)and the modified Barthel index were used to evaluate the patients' cognitive function and daily life ability before and after treatment.Results Before training there was no significant difference in average LOTCA and MBI results among the three groups.After 2 months of training,all three groups had significantly higher scores in both evaluations.Moreover,the combination group's average score on organization ability,perceptual ability,thinking operation ability and concentration,and also their average total score and MBI score were significantly better than those of the other two groups.Conclusions Eye acupuncture combines synergistically with cognitive rehabilitation training to ameliorate cognitive dysfunction after stroke.Together they promote cognition,ADL ability and an early return to normal family and social life better than either alone.

Objective To observe the effect of core stability training combined with eye acupuncture on motor function in patients with hemiplegia after stroke.Methods Eighty patients with hemiplegia after stroke were randomly divided into a treatment group and a control group (40 cases in each).Both groups were given regular rehabilitation training, but the patients in the treatment group also were taught core stability training of their waist and abdominal muscle groups, their shoulder muscles, trunk and pelvis.They were also given eye acupuncture.A trunk control test (TCT) , Berg's balance scale (BBS), the modified Barthel index (MBI), functional ambulation categories (FACs) and the Fugl Meyer assessment scale (FMA) were used to assess motor function before and after treatment.Results At the end of 6 weeks of treatment, all of the measurements in both groups had significantly improved.The average TCT, BBS, MBI, FMA, and FAC scores of the treatment group significantly exceeded those of the control group.Conclusions Core stability training and eye acupuncture together can significantly improve the motor function of hemiplegic stroke survivors.The combination therapy is worthy of clinical popularization and application.

ObjectiveTo explore the characteristics and risk factors of suicidal ideation among community subjects in Xiamen city and to provide appropriate suicide intervention strategies.MethodsUsing multi-stage stratified cluster sampling,12071 subjects aged 18 years and older were identified in Xiamen City.Their suicidal ideation was recorded with the investigation list made by Beijing Huilongguan Hospital Beijing Suicide Research and Prevention Center.Psychiatrists determined their diagnosis with Diagnostic and Statistical Manual of Mental Disorder 4th edition (DSM-Ⅳ).ResultsA total of 10757 subjects completed the survey,the completion was 89.1％.The life-time prevalence of suicidal ideation was 2.48％ (95％CI:2.19％ ～ 2.77％ ),the prevalence was higher in female(3.00％ ) than male( 1.88％ ) (RR =1.60,95％CI:1.24 ～2.06).Analysis of risk factors by single logistic regression showed that the suicidal ideation of persons were mostly in female,44 years and older group,in rural,not-being married,no medical insurance,poor mental or physical health in last month,being in hospital due to the mental problems,low quality of life,living alone,having blood relatives or acquaintance with suicidal behavior.While the risk factors by muhivariate logistic regression were ranked as follows:having acquaintance with suicidal behavior (OR =3.66,95％CI:2.44 ～5.50),being in hospital because of mental problems (OR =3.30,95％CI:1.08 ～10.09),poor mental health in last month(OR =3.17,95％CI:2.37 ～4.24),any blood relatives having suicidal behavior (OR =2.91,95％CI:1.61 ～ 5.25 ),low of quality of life (OR =2.21,95％CI:1.50 ～ 3.26 ),not-being married (OR =1.73,95％CI:1.28 ～ 2.32),living alone (OR =1.65,95％CI:1.18 ～ 2.32),being female (OR=1.57,95％CI:1.21 ～ 2.05).The prevalence of mental disorders in suicidal ideation was 46.4％.ConclusionThe prevalence of suicidal ideation is significantly higher in female residents than in male.Having acquaintance with suicidal behavior,being in hospital due to the mental problems as well as poor mental health in last month are the main risk factors of suicidal ideation.

Objective To investigate psychosocial factors for post-stroke depression (PSD). Methods 405 in-pa-tients with stroke were first screened for depression using Comprehensive International Diagnostic Interview-3.0. 22 pa-tients with depression were recruited as the depression group. From 383 patients without depression, 44 patients were se-lected and served as the non depression controlled group according to the sex and age paired with 1:2. Both groups were measured by using questionnaires including Life Event Scale, Simplified Coping Style Questionnaire, Social Support Rat-ing Scale, Activities of Daily Living Scale and Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form. Re-sults The score of passive coping was significantly higher in depression group than in non depression group [(1.2 ± 0.5) vs. (0.8±0.7), P<0.05]. The score of subjective support was significantly lower in depression group than in non depression group [(17.5±4.0) vs. (20.7±4.6), P<0.05]. Logistic regression analysis showed, minority nationality (OR=2.564, 95%CI:1.039~6.327) and passive coping style (OR=2.223, 95%CI:1.052~5.192) were risk factors for PSD, while subjective sup-port was protective factor for PSD (OR=0.884, 95%CI:0.793~0.986). Conclusions Passive coping style and low subjec-tive support may be the important psychosocial factors of PSD.
