Objective To investigate the prognostic value of plasma brain natriuretic peptide (BNP) in patients with acute cerebral infarction. Methods Sixty-five patients with first-ever acute cerebral infarction and 32 healthy controls were recruited. The neurological deficits in patients with cerebral infarction were evaluated by using Chinese Stroke Scale (CSS).Plasma BNP levels were detected by immunofluorescence technique. Death and recurrent stroke events were followed up. Plasma BNP levels were compared between an event group and a non-event group, and the relationship between plasma BNP levels and poor prognosis was analyzed.Results Plasma BNP levels in patients with acute cerebral infarction was significantly higher than those in healthy controls (238.7 ± 131.6 pg/ml vs 38.7±23.8 pg/ml, P <0.01). Nine patients (13.8%) died, and 8 (12.3%) had nonfatal recurrent stroke during the follow-up period. Compared to the non-event group, the baseline plasma BNP levels in the death/recurrent stroke event group were significantly higher (304.0 ± 134.9 pg/ml vs 214.4 ± 120.9 pg/ml,P < 0.01). There was significant correlation between plasma BNP levels and CSS scores (r = -0.359, P <0.05). After performing multivariate analysis of various risk factors, it found that BNP levels (OR = 3.5, 95 % CI 2.1 to 5.8, P < 0.01), advanced age (OR = 4.1,95% CI 1.7 to 9.2, P <0.01) and CSS scores (OR =2.6, 95% CI 1.6 to 4.3, P <0.01)were the independent predictors of poor outcome. Conclusions The increased BNP levels are the recent death and recurrent independent predictors in patients with acute cerebral infarction.

In the present paper, the safety of several major plant growth regulators to environment, agricultural products and animals was discussed synthetically. Paclobutrazol is stable in physical and chemical properties with slow degradation, and is able to secondly control the plant growth obviously, but it is degradable and becomes mutagenic substance, it can be enriched in the soil and is able to bio-magnify. Uniconazole is quick degradable with less residue. Ethephon is potentially mutagenic to the animals, it is degradable and can produce residues which will be harmfulto animal body. Moreover, their residual quantity differs with different organs in a plant and their residue in the leafage of several plants is in a high level.

This paper discusses issues involved in the deployment of the shelters of campaign-grade rapid medical support system in such aspects as entering of the vehicles,unloading of the shelters and grouping of the staffs. It suggests that the vehicles should rapidly move in at their positions and be butted bidirectional. As the system is deployed,such things should all be fixed as the position of the vehicles & equipments as well as the deployment motions and sequence. The system is positioned at hard surface,the shelters should be pushed towards the immobilized vehicles,but for the system located at soft surface,it is quite the contrary. With the above-mentioned measures implemented,the duration for shelters of campaign-grade rapid medical support system can be reduced largely.

Objective To evaluate the outcome of 23G minimally vitrectomy trocar on eyes with acute angle closure glaucoma.Methods A retrospective review was performed of patients with acute angle closure glaucoma who underwent combined compound trabeculectomy from September,2014 to June,2015 in Beijing MEM care system.Intraoperative 23G minimally vitrectomy trocar was used in all of the patients.30 eyes of 30 patients were enrolled in the study.All patients were followed up for 12 months.Visual acuity,intraocular pressure and complications were observed.Results No serious complications such as explosive choroid hemorrhage and retinal hemorrhage occurred during operation.All of 30 eyes maintained adequate pressure control.The average postoperative IOP was (15.93 ± 1.35) mmHg (1 kPa =7.5 mmHg),was less than the preoperative (56.34 ± 6.96) mmHg (P =0.00).And the visual acuity in 23 eyes were improved.Conclusion Combined trabeculectomy with 23G minimally vitrectomy trocar in acute angle closure glaucoma patients is a kind of safe and effective operation method,can obviously reduce the intraoperative explosive choroid hemorrhage.

Objective Leucine-rich repeat transmembrane neuronal protein 2 (LRRTM2) localizes to excitatory glutamatergic synapses,and triggers the formation of excitatory synapses.This study aims to investigate the expression of LRRTM2 protein in the temporal lobe tissue of SD rats induced by lithiumpilocarpine,and explore its roles in epilepsy.Methods Fifty-six Sprague-Dawley (SD) rats were induced by lithium-pilocarpine and randomly divided into 6h,24h,72h,7d,14d,30d and 60d subgroups.Eight SD rats were treated with normal saline instead of pilocarpine as controls. Expression of LRRTM2 protein was accessed by immunohistochemistry,immunofluorcscence and Western blot analysis. Results LRRTM2 protein mainly expressed in neurons of temporal lobe,gradually decreased in acute phase,and then up-regulated in latent and chronic periods.The immunohistochemistry A values in model rats from 6 h,24h,72h,7d,14d,30d and 60d subgroups were 0.286 ±0.012,0.227 ± 0.008,0.425 ± 0.015,0.509 ±0.019,0.579 ± 0.018,0.488 ± 0.018 and 0.566 ± 0.014,respectively,compared to 0.330 ±0.016 in control group ( t =3.965,11.987,9.131,14.121,20.452,12.929 and 22.786,all P＜0.05). Gray value ratios of LRRTM2/β-actin in different groups of model rats were 0.0354 ± 0.0043,0.0174 ± 0.0026,0.0685 ± 0.0064,0.0957 ± 0.0125,0.1044 ± 0.0103,0.0910 ± 0.0108,and 0.1012 ±0.0063,respectively,which were significant differences from control group (0.0471 ± 0.0033,t=4.354,14.191,5.989,7.541,10.565,7.730and15.316,allP＜0.05).Conclusions LRRTM2 protein gradually increases in the neurons of temporal lobe of SD rats treated by lithium-pilocarpine in silence and chronic phases,which indicates that it may play an important role in cpileptogenesis.

Objective To investigate the effect of the synthetic rehabilitation treatment using the assistive devices for children with cerebral palsy.Methods 60 outpatients (male 31,female 29) diagnosed as cerebral palsy in our hospital from June 2009 to June 2010 were divided into trial group (n =30) and control group (n =30).Both of the two groups received our rehabilitation treatment three times a week.Compared with the daily family rehabilitation training of the control group,trial group still received a daily rehabilitation treatment by their parents using the assistive devices under the guidance of the therapist.They were assessed with Gross Motor Function Measure 66 items version (GMFM-66)and 88 items version (GMFM-88) before and after 6 months treatment.Results The total score of GMFM-66 and each dimension score of GMFM-88 improved in both group after 6 months treatment,except the centrol group Lying & Rolling dimension.Trial group 51 ± 13 vs.44 ± 15,control group 42 ± 17 vs.38 ± 16 (t =-3.580,P =0.001).There was significant difference on the total score of GMFM-66 and the three dimensions score (Lying & Rolling,Sitting and Walking,Running & Jumping) of GMFM-88 between two group.Lying & Rolling:F =4.59,P =0.036; Sitting:F =6.40,P =0.014 ; Walking,Running & Jumping:F =4.35,P =0.041.Conclusion The synthetic rehabilitation treatment in Medical institutions associate with family rehabilitation treatment using the assistive devices can effectively improve the recovery of gross motor function in children with cerebral palsy.

Objective Congenital muscular torticollis (CMT) and developmental dysplasia of the hip (DDH) are common congenital problems in infants. Association between CMT and DDH has been reported in literatures. The aim of this study was to assess coexistence of DDH in infants with CMT and curative effects of its rehabilitative therapy. Methods In total, 187 infants less than two months old with CMT were recruited in the study. DDH was diagnosed and graded by Graf's bilateral hip type B ultrasonography and pelvic X-ray films. Massage manipulation, magnetic strapping, postural orthosis at home and heat compress were instituted for CMT and frog spica device and hip-flexion abduction plaster immobilization were instituted for DDH. Their early rehabilitative effects were evaluated. Results DDH was coexisted in 24 of 187 infants with CMT, with incidence of 12. 8%. The hips of 22 infants were graded as type Ⅱ b (91.7%) and two as type Ⅲ a (8.3%), and eight at the left side and seven at the right side.Comorbid hips completely recovered normal with early frog spica device and hip-flexion abduction therapy in 24 infants. Conclusions Coexistence of CMT and DDH are relatively common in infants. Type B ultrasonography can be used as a measure for screening DDH in neonates with CMT. Early rehabilitative therapy is effective for those coexisted with DDH and CMT at the same time.

Objective To determine the concept of functional evaluation for children with congenital heart disease in the views of International Classification of Functioning, Disability and Health (Children and Youth Version) (ICF-CY). Methods Clinical researches on children and adolescents with congenital heart disease nearly a decade were recalled from MEDLINE/PubMed and EMBASE. The concepts extracted were linked with ICF-CY. Results 224 researches were recalled. The oncepts linked with ICF-CY in 12 first categories, 28 second categories, of which 17 items were of body function, 2 of body structure, 6 of activities and participation, and 3 of environmental factors.Conclusion ICF-CY is a useful framework for functional assessment for children with congenital heart disease. It is important to make the measurement uniformity for comparability of the researches.

Objective To evaluate the health-related quality of life ( HRQL) of patients with adolescent idiopathic scoliosis ( AIS) before treatment. Methods Sixty-two female patients with AIS were evaluated using the Chinese version of Scoliosis Research Society's outcomes instrument 22 ( SRS-22) HRQL questionnaire before treatment. The patients were categorized into thFee groups: a mild deformity group with a major curve Cobb angle less than 30° ( n =14),a moderate deformity group with Cobb angles of 30° to 50° ( n =42), and a severe deformity group with Cobb angles more than 50° ( n =6). Results The severe deformity group scored lowest in the self-image domain.There was,however,no significant difference in the functional activity,pain or mental health domain scores between the three groups. Conclusions The Chinese version of the SRS-22 HRQL questionnaire can be used to assess the HRQL of Chinese AIS patients.AIS patients with a major curve Cobb angle more than 50° have relatively low self-image scores.
