ABSTRACT
Objective:To explore the chain mediating effects of anxiety/depression and metacognition between somatic symptoms and fear of disease progression (FoP) in gynecological tumor patients.Methods:A total of 208 gynecological tumor patients were investigated by general demographic data, fear of progression questionnaire-short form(FoP-Q-SF), hospital anxiety and depression scale(HADS), metacognition questionnaire(MCQ) and somatic symptom scale(SSS). SPSS 25.0 was used for Pearson correlation analysis. The significance of mediating effect was tested by deviation corrected nonparametric percentile Bootstrap method using SPSS macro program PROCESS.Results:The scores of FoP-Q-SF, depression, anxiety, MCQ and SSS were (32.41±10.43), (6.43±4.17), (7.51±4.10), (68.44±16.04), (20.58±15.70) respectively. 48.56% of gynecological tumor patients had dysfunctional fear of disease progression. Correlation analysis showed that FoP was significantly positively correlated with somatic symptoms ( r=0.394, P<0.01), anxiety ( r=0.640, P<0.01), depression ( r=0.533, P<0.01) and metacognition ( r=0.489, P<0.01). Mediating effect test showed that anxiety, depression and metacognition played a complete chain mediating role between somatic symptoms and FoP in gynecological tumor patients.The total effect of somatic symptoms on FoP was 0.320. Somatic symptoms indirectly affected FoP by influencing anxiety and metacognition, and the intermediary effect value was 0.242. Somatic symptoms indirectly affected FoP by influencing depression and metacognition, and the intermediary effect value was 0.212. Conclusion:Somatic symptoms can indirectly affect FoP through the chain mediation of anxiety/depression and metacognition.
ABSTRACT
Objective To understand the changes of schistosomiasis epidemic situation,so as to provide the evidence for for?mulating schistosomiasis control strategy in the Hexi reservoir area. Methods From 2012 to 2015,Xinyuan Village,Meishan Town in the north entrance of Hexi reservoir was selected as a monitoring site. According to the requirements of the monitoring program of schistosomiasis surveillance in Zhejiang Province,the Schistosoma japonicum infection was investigated by using the serological screening(IHA),and the basic situation of the surveillance site was also investigated. Results From 2012 to 2015,167 environments(21.68 hm2)were surveyed,and 2 slices(0.1 hm2)were found with Oncomelania hupensis snails. The detection rate of frames with snails was 0.12%,and the living snail density was 0.0192 snails per 0.1 m2. Totally 374 snails were dissected and no schistosome infected snails were found. A total of 970 local residents and 8 748 mobile people were investigated with the serological tests,and no schistosome infected people were found. In addition,3 085 cattle were investigated and no in?fected ones were found. Conclusion The schistosomiasis epidemic situation is stable in the Hexi reservoir area,but we still should strengthen the monitoring of imported source of infection and snail status,and increase the efforts of environmental trans?formation.
ABSTRACT
OBJECTIVE:To study the effects of electrolyte on the stability of the neonatal parenteral nutrition. METHODS:Under room temperature(25 ℃),the neonatal parenteral nutrition containing only monovalent or bivalent ion electrolyte(10% So-dium chloride injection,10% Potassium chloride injection,25% Magnesium sulfate injection,and Calcium gluconate injection) and containing both monovalent and bivalent ion electrolyte were investigated by the change of appearance to determine the pH val-ue,insoluble particles and the size and distribution (polydispersity index,PDI) within 24 h. RESULTS:The pH of the nutrition with electrolyte was over 5 and also met the quality requirements;there were no precipitate,flocculation and discoloration in the appearance;the neonatal parenteral nutrition containing only monovalent ion electrolyte appeared a small amount of hanging wall phenomenon for 24 h,but did not appear demulsification phenomenon;the neonatal parenteral nutrition containing only bivalent ion electrolyte appeared a small amount of hanging wall phenomenon and demulsification phenomenon for 24 h;the neonatal paren-teral nutrition containing both monovalent and bivalent ion electrolyte appeared a small amount of hanging wall phenomenon and de-mulsification phenomenon for 12 h and the hanging wall phenomenon was more obvious for 24 h. Meanwhile,a size bigger than 5μm microns and particle size bigger than 25 μm microns of insoluble particles appeared,and both the average particle size and PDI value were higher than those in the previous two situations(P<0.05). CONCLUSIONS:As more and more monovalent and biva-lent ion electrolyte being added into the neonatal parenteral nutrition,especially divalent ion electrolyte,the stability of the neona-tal parenteral nutrition decreases,which behaves as a phenomenon that the size of grains and the number of insoluble particles in-crease.
ABSTRACT
objective To understand the status of Oncomelania hupensis snail distribution and diffusion in main drainages of Hexi Reservoir and evaluate the snail control effect of the schistosomiasis control engineering of Hexi Reservoir. Methods The O. hupensis snails were investigated by using the straw curtain method and fishing net method in different areas of the main drainages of Hexi Reservoir and the results were analyzed. Results A total of 1 800 straw curtains were used and 37 snails were found in Naxi stream. Totally 5 870 kg floats were salved and no snails were found. Conclusion The schistosomiasis con?trol engineering of Hexi Reservoir is effective in the prevention of the snail diffusion but there are still snails in the upstream. Therefore the snail surveillance and control need to be strengthened.
ABSTRACT
Objective To evaluate the effect of schistosomiasis control projects in Hexi Reservoir on Oncomelania hupensis snail control. Methods The canal hardening+main water system widening+the overflow dam project,the concrete slope protec-tion,the banking and reclamation + concrete slope protection project,the environment reform project,and the comprehensive treatment were implemented in the tail area,the hydro-fluctuation belt,the rainwater harvesting zoon of the upstream area,the dam area,and the downstream area of the reservoir,respectively. The changes of the snail situation were investigated before and after the construction of the reservoir,and the snail control effects of the schistosomiasis control projects in different parts of the reservoir were analyzed. Results There were no Oncomelania snails found 3 years in the bottom area,dam area,hydro-fluctua-tion belt,tail region and downstream of the dam after the construction and storage of the reservoir and the implementation of the schistosomiasis control projects. In the rainwater harvesting zoon of the upstream area,the density of living snails decreased from 0.620 4 snails/0.1 m2 in 2009 to 0.113 2 snails/0.1 m2 in 2013,but the snail area still remained. Conclusions The schistosomia-sis control projects in Hexi Reservoir have effectively prevented the diffusion of Oncomelania snails from the rainwater harvesting zone of the upstream area to the dam area,and they are effective in the snail control.
