Objective To assess the importance of initial resuscitation, prevention and management of the early complication in acute cervical spine injury. Methods Initial resuscitation of 715 early complications of 10 types and their prevention and management in 194 cases with acute cervical spinal cord injury admitted from 1996 to 1998 were reviewed. Results Mortality in early stage could be markedly reduced with routine and normal initial resuscitation, pulmonary complications were the main cause of death. Early complications delayed the possible surgical treatment, affected the treatment results, increased the cost and duration of hospitalization and difficulty of rehabilitation. Conclusions Early complications of cervical spine injury mostly occur in the first few days and can be predicted. Proper prevention and treatment of it will benefit the recovery of the neural lesion and following rehabilitation.

ObjectiveTo understand the feature of blood pressure in children aged 7 to 12 years in Zhengzhou.Methods According to stratiifed cluster random sampling method, children aged 7 to 12 years in ifve schools from three urban and two suburban counties in Zhengzhou were analyzed. The height, weight, waist circumference, hip circumference, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured and analyzed.Results The survey included total 6460 children aged 7 to 12 years, 3206 urban children (49.63%), 3254 suburban children (50.37%), 3525 boys (54.57%) and 2935 girls (45.43%). SBP in boys [(117.86±18.18) mmHg] was signiifcantly higher than that in girls [(113.82±13.11) mmHg (t=3.16;P=0.002). The incidence of hypertension in children in Zhengzhou was 7.52%. The blood pressure in boys was higher than that in girls (χ2=9.66,P=0.002). The blood pressure in urban boys and girls was higher than that in suburban boys and girls respectively (χ2=24.15, 14.39;P=0.000). The SBP and DBP had positive correlation with age, height, weight, BMI, waist circumference in boys (P<0.01). The SBP had positive correlation with age, height, weight, BMI, waist circumference in girls (P<0.01). Conclusions The blood pressure is higher in boys than in girls, which also is higher in urban children than in suburban children in Zhengzhou. The SBP is related to the age, height, weight, BMI, waist circumference.

Objective To investigate the clinical nursing path on the psychological status of cerebral infarction patients hospitalized for the first time.Methods Two hundred cerebral infarction patients hospitalized for the first time were equally randomized into the observation group and control group:the former used conventional nursing method and the latter a clinical nursing path.The self-rating depression scale(SDS)and self-rating anxiety scale(SAS)were used to assess their psychological state.Results After intervention,the scores on SDS and SAS in the former group were significantly lower than those in the latter group(all P<0.05). The satisfaction rate in the former was higher than that of the control(P<0.05).Conclusion The clinical nursing path makes it possible to effectively alleviate the psychological burden of the cerebral infarction patients hospitalized for the first time and improve the patients’satisfaction with nursing working.

Objective To analyze Vitamin D nutritional status of children and their height growth relationship in Wanzhou dis-trict of Chongqing .Methods Electrochemiluminescence immunoassay method was used to detect serum 25 hydroxyvitamin D [25 (OH) D]concentrations in 2 727 Children from Wanzhou district of Chongqing ,analyzing the correlation of Vitamin D and children age ,gender ,height ,parental height and other factors .Results There was significant difference in serum level of 25(OH) D among different age groups(P<0 .01) ,there was significant difference between boys and girls among the same age groups of 5 months ,6 months ,4 years old ,5 years old .Children′s height consistented with the national average 4 -6 years ago in Wanzhou District ,but Since then ,gradually felled behind .After adjustment for age ,sex ,parental height ,measured seasonal and other factors ,serum 25 (OH) D concentration was positively correlated with height (r=0 .462 5 ,P<0 .01) .Conclusion 25(OH)D levels were closely re-lated with the development of children′s height .Thus ,children generally poor 25(OH)D nutritional status in Wanzhou district should arouse the attention of parents and clinicians .

Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.
