Objective To evaluate the effect of health education path on advanced schistosomiasis patients with splenomega-ly in perioperative period. Methods A total of 60 advanced schistosomiasis patients with splenomegaly in perioperative period were randomly divided into an observation group and a control group (30 cases each group). The patients in the observation group were intervened by the nursing and health education from admission to discharge according to the standardized process of health education path,while those in the control group were implemented with the conventional health education. Then the satis-faction of nursing work,hospital stays,hospitalization expenses and mastery of health knowledge of the patients in the two groups were investigated and the results were compared. Results The satisfaction rates of nursing work of patients in the obser-vation group and the control group were 90%and 60%,respectively,the difference between them was statistically significant (χ2=7.57,P<0.05). The average hospitals stays of the above two groups were 14.0 ± 3.5 d and 19.0 ± 6.8 d(t=2.85,P<0.01),respectively,and the average hospitalization expenses were(1.5 ± 0.5)thousand Yuan and(2.2 ± 0.7)thousand Yuan (t=24.57,P<0.01),respectively,both of the differences were statistically significant. On the 10th day after surgery,the mas-tery rates of the health knowledge of the two groups were 96.7%and 50.0%,respectively,the difference was statistically signifi-cant(χ2=16.86,P<0.001). Conclusions The implementation of the health education path can promote the rehabilitation of advanced schistosomiasis patients with splenomegaly,and increase the satisfaction as well as improve the mastery of the health knowledge of the patients. Meanwhile,it also can cut down the hospital stays and save the hospitalization expenses.

The prevalence of acute flaccid paralysis (AFP) associated with EV71 and the genetic variation in Fujian , China from 2003 to 2012 was investigated in this study .Descriptive epidemiology was used to analyze the epidemiologic and clinical features of AFP cases associated with EV 71 .Phylogenetic analysis was performed to explore the genetical characteris-tics of EV71 based on the complete VP1 nucleotide and amino acid sequences .Results showed that the mean incidence of EV71-associated AFP in children under 15 years old was 2 .24/10 000 000 in Fujian Province during 2003 and 2012 ,based on the number of EV71 isolates and the reported AFP cases .And the incidence has increased since 2008 .The EV71 strains isolated from the AFP cases or from the healthy contacts were distributed in 9 prefectures of Fujian Province ,most in the months of May and June .Of 76 .0% (19/25) of AFP cases associated with EV 71 were the children under 3 years and the male-to-female ratio was 1 .5 :1 .Twenty out of twenty-two cases (90 .91% ) had fevers before the onset of paralysis .Most cases had unilater-al limb paralysis (14/22 ,63 .6% ) .Typical manifestations of hand-foot-and-mouth disease (HFMD) were observed in five cases before the onset of paralysis .Residual paralysis was observed in two cases during the follow-up visits .The strains isolated from 25 cases belonged to genotype C4 .All other strains belonged to subtype C4a except the subtype C4b strains isolated in 2003 .The homology among the strains was high in 2009-2011 ,and the homology among these strains and the representative strains in Fuyang ,Anhui Province was also in the high level .Therefore ,it was possible that the isolated strains had the same origin and might cause the epidemic .In conclusion ,an AFP surveillance system could be developed for analyzing the incidence of AFP associated with EV71 ,determining the features of the isolates ,and describing the intensity and trends of EV71 epidem-ics .

ObjectiveTo explore the effect of combined usage of expanding coronal decompressive craniectomy and sequential dural incision for treating severe bilateral frontal contusion (SBFC).Methods Forty-three patients with SBFC were randomly divided by sequential single day after hospitalization into two groups.Observation group(23 cases) treated with expanding coronal decompressive craniectomy and sequential dural incision.Control group (20 cases) treated with standard hemicraniectomy and routine dural incision.ResultsThe occurrence rate of acute cephalocele was significantly lower in observation group [ 17.4％(4/23) ] than that in control group [ 55.0％(11/20) ] (P ＜ 0.05).According to Glasgow outcome scale (GOS) score of six-month observation after operation,17 cases(73.9％,17/23) of observation group got favourable recovery or moderate deficit,other 6 cases(26.1％,6/23) got severe deficit,persistent vegetative status or death.While only 8 cases(40.0％,8/20) got favourable recovery or moderate deficit,12 cases ( 60.0％,12/20 ) got severe deficit,persistent vegetative status or death in control group.The rate of favourable recovery and moderate deficit of two groups had statistical significance (P ＜ 0.05).ConclusionCombination application of expanding coronal decompressive craniectomy and sequential dural incision is an effective method to treat patients with SBFC,and can obviously improve the rate of successful rescue and decrease the rate of mortality and disability.
