Objective To screen nursing workload items in the perioperative period of lumbar disc herniation by using Delphi method for providing scientific basis in order to undertake nursing care cost calculation of single disease. Methods The measuring content of nursing workload was firstly designed on the basis of consulting literature and experts discussion,then two rounds of consultations were made with experts by using the Delphi method. Results Valid questionnaires collected back were 35 and 37,respectively, accounting for 89% and 94% in the two rounds of consultations with the experts,by which fully reflected the support of experts to the study. The average number of authoritative coefficients in the two rounds of consultations with the experts was respectively 0.79, 0.88,which indicated high reliability of the consulting. The overall coordination index for nursing care items in the preoperative/intraoperative/postoperative period of consulting experts respectively was 0.265/0.305/0.359 and 0.435/0.316/0.425, which had statistical significance and indicated the good coordination among the experts advice in determining the nursing care items and the desirability of the results. Conclusions Measurement items of nursing workload in perioperative period of lumbar disc herniation had been screened scientifically and reliably,which could accurately measure the nursing workload of the disease and lay the foundation for further accounting of nursing care cost.

Objective To evaluate the effect of atorvastatin on human carotid plaque by high resolution nuclear magnetic resonance imaging(MRI 3. 0T). Methods Forty patients with carotid artery plaque were treated with atorvastatin at the dose of 20 mg daily for one year. Changes of the artery plaques were observed by MRI,and the levels of blood lipoproteins and C reactive protein( hs-CRP)were detected. Results After the treatment with atorvastatin for 6 months and 1 year,the number and average thickness of plaques were reduced. One year after the treatment,average thickness of stable plaques dropped from (2. 41±0. 54)mm to(2. 17±0. 49)mm,and the size of the unstable plaques decreased from(2. 38±0. 89)mm to(2. 01± 0. 32)mm,with significant differences(P﹤0. 05). The levels of TC,TG,LDL-C and Hs-CRP were significantly decreased(P﹤0. 05)and the level of HDL-C was increased. Conclusion High resolution nuclear magnetic resonance( MRI3. 0T)can clearly display the components of the atherosclerotic plaque and the degree of artery stenosis. Atorvastatin exerts a significant effect on carotid plaque by promoting the regression of the carotid atherosclerosis plaque.

OBJECTIVE:To test the static balance function of boys aged from 6 to 8 years and then to establish a system of evaluating the static balance function.METHODS:A total of 388 boys aged from 6 to 8 years were randomly selected from 16 kindergartens of 8 counties(cities)in 4regions of Hebei Province.The inclusive cdteria were as follows:no systematic training of sports,no myopia,normal body shape and no obvious obesity.The balance force-measuring plates made by Hefei Institute of Intelligent of Chinese Academy of Sciences,computer and the supporting software were adopted.The subjects received an indoor test of 6 testing postures,namely,standing on two feet with eyes open(and closed),standing on left leg with eyes open(and closed),standing on right leg with eyes open(and closed).Six indexes relating to balance abilities including the mean of X direction,the mean of Y direction,R value,track length per unit time and track location variance of the envelop area.RESULTS:The original screening of all indexes showed that 6 kinds of postures reduced to 4 and that indexes reduced from 36 to 24.The second screening with cluster analysis which was conducted to the 4 kinds of postures showed that 24 indexes reduced to 17 when selecting typical indexes from each cluster.The third screening with factor analysis showed that 7 out of the 17 indexes were remained.Seven representative indexes corresponding to these 7 factors were concluded and considered as the comprehensive evaluation indexes of the static balance.The comprehensive static balance evaluation index systems for 6-year-old.7-year-old and 8-year-old boys were established respectively.CONCLUSION:Three systems for evaluating the static balance function of the boys aged from 6 to 8 years are established successfully based on 7 indexes.The evaluation of static balance function should be based on the comprehensive evaluation of multiple indexes.The evaluation indexes for 6-year-old,7-year-old and 8-year-old boys are identical in number,but different in content.Accordingly,a specific evaluation index system should be established for them separately.

Objective:To explore the influences of different sexes and ages on children static balance at the basis of quantitative comparison study of static postural balance of children aged 6-8(-year-odl).Method:A total of 499 children aged 6-8-year-old were recruited,which include 254 boys and 245 girls.Static postural balance test of these subjects was performed by using KY-1112 system for stabilometric analysis with subjects opening and closing eyes situations.Result:①There was a significant gender difference in static balance.At gender comparison,there was a significant difference on 3 indicators at the situations with eyes opening(P<0.05),and 3 indicators at the situations with eyes closing(P<0,01).②A significant difference Was shown in age comparison on 5 indicators(P<0.05).The mean of 5 indicators decreased with age growing.As compared with the value among Eve Area(with eyes opening and closing)and Track location Variance (with eyes opening).there Was a significant difference between children aged 8-year-old and 6-7-year-old(P<0.01),and no significant difference between 6-year-old and 7-year-old.There was a very significant difference on the LNG indicators at the situations with eyes opening and closing(P<0.01).③The value R indicator Was less than 1.Conclusion:To the children aged 6-8-year-old,there was significant gender difference in static balance,the balance function of girls was better than that of boys;there was significant age difference in static balance,with age growing the static balance rose also;relatively speaking,the gravity center shaking area was larger at forward and backward than that at leftward and rishtward.

Objective To investigate the relationship of cellular immunity of the hand-foot-mouth disease (HFMD) children and the disease severity and the variation following the recovery of disease.Methods A total of 560 HFMD cases was collected,and divided into severe and common groups.Another 120 cases were collected for comparison.T cell subsets (CD3 +,CD4 +,and CD8 +) rates were tested.The difference in cell immunity in each group were compared,and the comparison of cell immunity improv-ment during acute and recovery periods was conducted at the same time.Results In the 560 cases of children with HFMD,CoxA16-positive rate in common group was higher than that in severe group (x2 =280.72,P ＜0.01,severe cases); EV71 and other virus positive rates in severe group were higher than that in common group (x2 =127.75,P ＜ 0.01,x2 =5.43,P ＜ 0.05).Cell immunity was compared among3 groups (t =9.82,4.98,3.06); CD3+,CD4+,CD8+ results,tested within 2h after admission and after 1 week,were compared between severe and common groups (common group t =7.73,3.86,4.71; severe group t =6.13,2.60,3.36).Compared to severe group,cell immunity improvement was more obvious between before and after 1-week treatment in common group (t =2.57,2.51,2.95).The difference was statistically significant (P ＜ 0.05).Conclusions According to the etiology test of children with HFMD,CoxA16-positive rate was higher in common group; EV71 and other virus positive rates were higher in severe group.Cell immunity function decreased in severe and common group at the beginning of the disease; it was,however,significantly restored after 1-week treatment; and it was related to the severity of clinical symptoms.

Objective To investigate and analyze the adverse effect(AE) of methotrexate(MTX)in rheumatoid arthritis(RA).MethodsThree hundred and twenty-five RA patients were investigated with a questionnaire in clinical service of department of Rheumatology and Immunology, Peking University People's Hospital. SPSS 11.5 software was used for statistical analysis. Results① The total prevalence of AE was 34.2％. Among these, gastrointestinal AE were the most common, others included elevated liver enzymes,leucocytopenia,alopecia and dental ulcer. The incidence of drug withdrawal of MTX was 13.2％, elevated liver enzymes was the most common reason of withdrawal, other reasons were gastrointestinal AE, leucocytopenia,dental ulcer and alopecia. The gastrointestinal AE and dental ulcer occurred within one week after initiating the medication in average, while elevated liver enzymes and leucocytopenia usually occurred at about 1～2 months after the medication. ②The incidence of AE increased with the dosage. ③ Folic acid could significantly decrease the total incidence of AE(P＜0.05). The incidence of gastrointestinal AE, elevated liver enzymes,leucocytopenia and dental ulcer couldbe reduced by folic acid supplementation(P＜0.05).Conclusion The AE of MTX in RA treatment are common, many of which are slight and could be improved by reducing the dosage or symptomatic treatment. The AEs of MTX can be improved by folic acid supplement treatment.

Objective To evaluate the relative efficacy of different dosages of Calf Pulmonary Surfactant (Calsurf) administration in premature infants with established respiratory distress syndrome (NRDS).Methods Four neonatal intensive care units in Jiangsu province were enrolled.Premature infants,birth weight ＜ 2 500 g,with NRDS,received 70 mg/kg (61 cases)or 100 mg/kg (69 cases)Calsurf.Clinical and respiratory parameters were recorded.The primary outcome measures were blood gas analysis of 1 h,12 h and 36 h after administration,the need for oxygenation and ventilatory requirements and the adverse events of NRDS.Results Arterial oxygen tension[pa (O2)] results in a significant improvement(80.27-±36.81) mmHg,(73.03 ±24.94) mmHg and (72.35 ± 24.72) mmHg at 1 h,12 h and 24 h in higher dose group(P ＜ 0.05),(67.95 ± 23.79) mmHg,(72.35 ± 24.72) mmHg in 24 h,as compared with the lower dose group at the same time [(67.07 ± 19.94) mmHg,(62.93 ± 21.71) mmHg,(67.95 ±-23.79) mmHg] (P ＞ 0.05).Inspired oxygen (FiO2) and pa (O2) decreased after administration in two groups and the duration of FiO2 decline lasted to 48 h (all P ＜ 0.05).The oxygen index (OI) was improved after Calsurf administration,especially in the infants who received 100 mg/kg of Calsurf with 6.1 ± 2.8,5.6 ± 3.3,5.5 ± 3.5,5.8 ± 4.5,5.3 ± 3.1 in 1 h,12 h,24 h,36 h,48 h,respectively(P ＜ 0.01).The arterial-to-alveolar oxygen tension ratio (a/APO2) of 100 mg/kg group was reduced significantly in 1 h,12 h,24 h,36 h,48 h with 0.39 ±0.22,0.42 ±0.20,0.45 ± 0.22,0.44 ± 0.22,0.46 ± 0.21 as compared with 0.27 ± 0.18 which was at the time point before administration (P ＜ 0.01).Although not statistically significant,the mean time of duration of mechanical ventilation and oxygen inhalation of higher dose group were decreased as compared to the lower dose group [(94.54 ± 113.44) h vs (109.27 ± 124.87) h (P＞0.05) and (259.10 ±280.45) vs (372.31 ±398.08) h(P ＞0.05)].There were no significant differences in the rates of other adverse events such as pneumonia,pneumothorax,intracranial hemorrhage,patent ductus arteriosus (PDA),pneumorrhagia,necrotizing enterocolitis,septicemia between two groups (P ＞ 0.05).Conclusions Calsurf given to preterm infants with NRDS at a dose of 100 mg/kg resulted in a higher Pa (O2),a/APO2,better OI and lower FiO2 as compared with those receiving 70 mg/kg.The need for mechanical ventilation and oxygen supplement were reduced with higher-dose administration.Large dose of Calsurf did not increase the risk of complications as mentioned above.
