Methods The 100 patients with cerebral palsy were randomly divided into two groups. In group A, the patients were treated by SPR, and in group B, the patients received rehabilitation training after SPR for 12 months. One year later the curative efficacy of all patients was evaluated and compared between the two groups.Results The effective rate was 52% and 76% in groups A and B respectively. Conclusion It is very important that the patients receive systematic rehabilitation training after SPR so as to gain a most satisfied functional recovery.

Objective To compare the effect of intravenous resuscitation with sodium pyruvate (Pyr) Ringer solution against lactated Ringer solution on hemodynamic and organ functions during shock stage in dogs with burn.Methods 28 Beagle dogs were subjected to 50％ total body surface area (TBSA) burn,and they were divided into three groups:burn injury without fluid resuscitation (N R,n =8),Ringer lactate solution(RL,n =10),and Pyr Ringer solution (RP,n =10).They were given intravenous fluid resuscitation according to Parkland formula 30 minutes after burn.The hemodynamics,organ functions and mortality were observed in conscious state before burn injury,and 2,6,8,12,24 hours after burn injury.Results Within 24 hours after burn,all the dogs in NR group died,and those in RL and RP groups were all alive.At 2 hours after burn,the mean arterial pressure (MAP),cardiac index (CI),dp/dt max of left ventricular contractility were significantly reduced in NR,RL and RP groups compared with those before injury [MAP(mmHg,1 mmHg =0.133 kPa):45.33 ± 7.78 vs.141.67 ± 5.98,91.33 ± 10.25 vs.142.33 ± 6.16,98.67 ± 9.54 vs.142.83 ±5.47; CI (mL·s-1·m-2):8.17 ±0.83 vs.48.34 ±3.33,16.84 ±2.17 vs.47.34 ± 1.67,19.00 ± 1.50 vs.47.34 ± 1.33; dp/dt max (mmHg/s):426.83 ± 51.91 vs.1 372.50 ± 39.61,594.00 ± 88.23 vs.1 363.83 ± 44.92,645.00 ±66.82 vs.1 395.83 ± 19.49,all P＜0.05],and the systemic vascular resistance (SVR) and alanine transaminase (ALT),creatinine (Cr),serum MB isoenzyme of creatine kinase (CK-MB),diamine oxidase (DAO) were significantly higher [SVR (kPa·s ·L-1):1 322.50 ±36.37 vs.281.45 ± 8.84,777.50 ±41.84 vs.289.72 ± 6.70,571.40 ±40.01 vs.286.27 ±8.66; ALT (U/L):89.50 ±4.11 vs.40.57 ±3.63,89.25 ±4.88 vs.37.92 ± 2.62,86.30 ±5.61 vs.38.47 ±3.50; Cr (μmol/L):75.62 ±4.61 vs.41.58 ±2.78,77.00 ±5.92 vs.46.55 ± 3.17,74.13 ±2.56 vs.45.65 ± 1.83; CK-MB (kU/L):13.122 ±0.282 vs.1.557 ±0.009,8.885 ±0.272 vs.1.497 ± 0.009,8.692 ± 0.180 vs.1.490 ± 0.005; DAO (kU/L):2.26 ± 0.14 vs.0.25 ± 0.02,1.50 ± 0.07 vs.0.25 ± 0.01,1.37 ± 0.07 vs.0.25 ± 0.02,all P＜0.05].All parameters in NR group kept on worsening till death,while hemodynamic and organ functions of two intravenous resuscitation groups were gradually improved,CI,SVR and DAO in RP group were significantly superior to those of RL group from 2 hours on after burn (all P＜0.05),and dp/dt max and CK-MB in RP group were significantly better than those of RL group from 6 hours on after burn [dp/dt max (mmHg/s):1 082.33 ± 63.59 vs.1 018.60 ± 47.36,CK-MB (U/L):7 898.70 ± 255.74 vs.8 438.70 ± 442.00,all P＜0.05],and MAP (mmHg) was significantly better than that of RL group at 6 hours (124.67 ± 9.39 vs.114.33 ± 9.16,P＜0.05),and Cr (tμmol/L) was significantly better than that of RL group from 24 hours on after burn (53.42 ± 4.99 vs.60.77 ± 3.11,P＜0.05).Conclusion The Pyr Ringer solution was superior to the Ringer lactate solution in improving hemodynamic and organ functions for intravenous resuscitation in dogs with 50％TBSA full thickness burn.

Objective:To find out the key demand and connection point of health quality education for students of different stages by analysis of their health quality characteristics and the main contribution path, and then explore strategies to improve health quality. Methods:The stratified random cluster sampling method was carried out to select the sample population in Hangzhou. The variance analysis, curve fitting and multivariate linear regression analysis were used to analyze health quality characteristics and the main contribution path. Results:The health quality of pri-mary school students was best;the difference in quality between college students and junior high school students was not statistically significant ( P>0. 05 );and high school students had the worst health quality. The high school stage is the weakest link of health quality education. The order of the health education path and the means for improving the health quality of college, high school, and primary school students differ. With the improvement of students’ lev-el, the students that require physical quality promotion gradually decreases; the moral quality demand remains sta-ble;and the psychological quality and social adaptation ability present the tendency of a gradual increase. Conclu-sion:Student health quality shows a tendency to decreases with the rise of learning phase. The education departments should foster health consciousness and habits for students, form a healthy lifestyle behavior and ways of thinking for high school students, shape healthy personalities to improve health literacy and social adaptation abilities for college student, which is the key strategy for promoting the health quality of all-round development of the students and a-chieve the primary education goal of “health education”.

Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.

Objective To investigate the clinical value of a three-dimensional motion analysis system by using the body segmental method for testing the balance of hemiplegic stroke patients.Methods Twenty stroke patients with hemiplegia were measured using the lower extremity Fugl-Meyer motor assessment (FMA-L),the Brunel balance assessment (BBA),the Berg balance sale (BBS) and a 5 m timed up-and-go test (5m-TUGT).The three-dimensional motion analysis system using the body segmental method was applied in three positions-sitting,standing and walking.Spearman's rank correlation coefficient was used to determine the extent of correlation between the values measured by the three-dimensional motion analysis system and the FMA-L,BBA,BBS and 5m-TUGT results.Results Some motion analysis variables (MSAx,MSVx,MSAy,MSVy and SPxy,SP3-D) are recorded in sitting and standing,while the center of gravity (COG) swing in the horizontal plane and some other variables (MSAx,MSVx and SPxy and SP3-D) are measured while walking.Anterior-posterior COG swing had a high negative correlation with the FMA-L,BBA and BBS scores and a high positive correlations with 5m-TUGT times.But except in sitting,MSAz and MSVz were both uncorrelated with FMA-L,BBA or BBS scores or with 5m-TUGT times.COG swing in the horizontal plane in sitting and standing apparently correlates with lower extremity motor function,balance,and walking ability.However,only the X axis swing parameters of the COG while walking correlated with lower extremity motor function,balance or walking ability.Conclusions A three-dimensional motion analysis system using the body segmental method can be used clinically to monitor patients' balance in real time and dynamically in different positions and activities,and it can be used to predict motor function and balance control in hemiplegic stroke patients.

Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P ＜ 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P ＞0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P ＜0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.
