Objective To classify and grade the environments with Oncomelania hupensis snails inside embankment in marsh-land and lake areas,so as to improve the work efficiency and realize the systematic management. Methods The schistosomiasis endemic area Liaodi and Xiongdi villages in Jiangling County,Hubei Province were selected as the experiment villages,and the environments with snails in the two villages were divided into sections with a length of 500m,then the snail situation were sur-veyed by the systematic sampling method with 10m and 50m a frame respectively. The environments were classified according to the discovery of infected snails and wild fecal contamination,and the numbers of sites with snails and their areas in different class-es were recorded. Meanwhile,the data of sites with infected snails in Jingzhou City during the recent 5 years were collected and graded according to the average density of snails,so as to discuss the correlativity between the grades of environments with snails and the numbers of sites with infected snails and the occurrence rate of frames with snails. Results There were 1 967 sites with in-fected snails in Jingzhou City during the recent 5 years,and there was a positive correlation between the grades of environments with snails and the occurrence rate of frames with snails(rs=0.77,P<0.01),when the grade was 5,the constituent ratio of num-bers of sites with infected snails was 3.1%,and when the grade was 2-3,the ratio raised to 56.3%. There were 39 sites with snails in the two villages,the Class 1,2 and 3 environments included 1,18 and 20 sites,with the areas of 1 080,51 640 m2 and 41 220 m2 , respectively. There were no statistically significant difference between the grades divided by snail survey with 10m and 50m a frame(χ2=4.667,P>0.05),but the time-consuming of the former was 3 times of the latter. Conclusions The classification and grading of the environments with snails inside embankment in marshland and lake areas can master the key point of the snail survey. The subsection and setting frames at a suitable distance can save time and manpower,improve work efficiency,as well as understand the distribution of snail status of the environment with snails,which can realize the sort management of the snail envi-ronments inside embankment.

Objective To explore the protective affect of individual earmuffs in microtia reconstruction using tissue expander.Methods 95 patients performed the implantation of tissue expander had been grouped into the experimental group(49 cases)and the control group(46 cases).Patients in the experimental group wore individual earmuffs,whereas patients in the control group wore traditional earmuffs.The survey including the information of patients' experience in wearing the earmuffs was carried out on the day when patients were given auricular reconstruction.Data collected from the two groups were analyzed to evaluate the aspects of permeability and safety.Results Patients in the experimental group complained less discomfort in sultry in permeability and tinnitus than patients in the control group.From the perspective of safety,there was no complaints of mosquitoes climbing into the earmuffs from the two groups.Because of the good adhesiveness of the individual earmuffs to the skin,the incidence of redness of skin in the experimen tal group was significantly lower than that in the control group.Conclusions Individual earmuff is a safe and comfortable nursing appliance which is practical for clinical application because of its good permeability,adhesiveness and less incidence of redness of skin.

Objective To explore the reasons for withdrawal from peritoneal dialysis (PD) in our hospital.Methods This was a single-center,retrospective cohort study.Patients who started PD in the Department of Nephrology,the First Affiliated Hospital of Nanchang University from November 1st,2005 to February 28th,2017,were enrolled,and followed up to May 31,2017.Patients who continued PD after May 31,2017 were as the control group.Patients who withdrew from PD were divided into 4 subgroups:death group,hemodialysis group,kidney transplantation group and loss of follow-up group.The clinical characters of 4 subgroups were compared with the control group.Results A total of 998 patients were enrolled with age of (49.36± 14.94) when PD started and median dialysis duration of 27.13(12.84,42.29) months,in whom 570 patients (57.11％) were male.Five hundred and seventeen dropout events were recorded,and the dropout rate was 51.80％.The main reason for withdrawal from PD was death (258 patients,49.90％),followed by hemodialysis (166patients,32.11％),kidney transplantation (66 patients,12.77％) and loss to follow-up (27 patients,5.22％).The leading cause of death was cardio-cerebro-vascular diseases (136 cases,52.71％),followed by infection (42 cases,16.28％),dyscrasia (20 cases,7.75％) and tumor (5 cases,1.94％).The main reason for transfering to hemodialysis was insufficient dialysis (76 cases,45.78％),followed by peritonitis (55 cases,33.13％) and catheter dysfunction (24 cases,14.46％).Compared with those in the control group,in the death group patients were older at PD commencement,and had higher proportions of hypertension,diabetes and cardio-cerebro-vascular diseases (all P ＜ 0.05).The proportions of male and diabetes mellitus were higher in the hemodialysis group than those in the control group (both P ＜0.05).Biochemical indicators showed that serum albumin and blood phosphorus were lower in the death group than those in the control group (both P ＜ 0.05);blood albumin was significantly lower in the hemodialysis group than that in the control group (P ＜ 0.05).Conclusions The main reasons for withdrawal from PD in our center are death and transfering to hemodialysis.The cardio-cerebro-vascular disease is the leading cause of death,and inadequate dialysis is the main reason for transfering to hemodialysis.

Objective:To investigate the differential expression of long non-coding RNA (lncRNA) in placental tissues of women with preeclampsia (PE) and the effect of MIR210HG on the biological function of HTR8/SVneo cells.Methods:A total of 39 cases of PE women (PE group) and 39 cases of normal pregnant women (CTL group) admitted to the Affiliated Hospital of Qingdao University from July 2018 to July 2019 were collected. (1) Transcriptome sequencing (RNA-seq) was used to analyze the differentially expressed lncRNAs in the placental tissues of the two groups. (2) The expression level of MIR210HG, one of the differentially expressed lncRNAs, in the placental tissues of the two groups was detected by real-time quantitative PCR. And the correlations between the expression level of MIR210HG and systolic blood pressure, diastolic blood pressure and neonatal birth weight were analyzed. (3) The constructed small interfering RNA and negative control (NC) RNA were transfected into the HTR8/SVneo cells. The cells were divided into MIR210HG knockdown (KD) group and NC group. The effects of living cell counting (CCK-8) and transwell assay on the proliferation and migration of HTR8/SVneo cells were detected. (4) RNA interacting with MIR210HG was predicted using the Encyclopedia of RNA Interactomes (ENCORI) database. Gene Ontology (GO) functional annotation, Kyoto Encyclopedia of Gene and Genomes (KEGG) and BioCarta pathway enrichment analysis were performed.Results:(1) A total of 26 significantly differentially expressed lncRNAs were found by RNA-seq, among which 21 lncRNAs were up-regulated and 5 lncRNAs were down-regulated. (2) The relative expression level of MIR210HG in the PE group was significantly higher than that in the CTL group (9.30±1.90 and 1.10±0.20, respectively; t=4.425, P<0.01). The relative expression level of MIR210HG had positive linear correlation with systolic blood pressure ( r2=0.234, P<0.05) and diastolic blood pressure ( r2=0.190, P<0.05), but had a negative linear correlation with newborn birth weight ( r2=0.157, P<0.05). (3) Compared with the NC group, the proliferation and migration ability of HTR8/SVneo cells in the KD group were increased (all P<0.05). (4) A total of 38 RNAs that might interact with MIR210HG were predicted by ENCORI database. GO functional annotation analysis showed that MIR210HG might be involved in the functions of 27 pathways, including the regulation of production of molecular mediator of immune response, etc; KEGG pathway analysis showed that MIR210HG might be involved in the function of 8 pathways including allograft rejection, etc; Biocarta pathway analysis showed that MIR210HG may be involved in the functions of 8 pathways, including the eukaryotic initiation factor (eIF) pathway, etc. Conclusion:The expression of MIR210HG is up-regulated in the placental tissue of PE women, and MIR210HG might be a regulator of the biological behavior of trophoblast cells.

Objective To implement a two?level community?based health education pattern of schistosomiasis in residents of endemic areas in marshland and lake regions,so as to explore the suitable pattern of health education under hypo?endemic situa?tion. Methods Two schistosomiasis endemic villages in Jiangling County,Hubei Province were collected as study areas,and among which,one village was treated as an intervention group,where the two?level community?based health education pattern as well as regular control measures was implemented;the other village was a control group,where only regular control measures were implemented. The awareness rates on schistosomiasis control,the rates of correct behavior and the compliance rates of ex?amination,treatment and chemotherapy of the two groups before and after the intervention were compared. Results According to the results of the baseline survey in 2014,the awareness rates of schistosomiasis control of the intervention and control groups were 84.00%and 77.45%,respectively,the correct rates of behavior of the two groups were 72.00%and 63.73%,respectively, and the compliance rates of the treatment were 80.36%and 82.28%,respectively,there were no statistically significant differ? ences between all the above rates of the two groups(all P>0.05). After the intervention of the two?level community?based health education,the correct rates of behavior,and the compliance rates of examination and chemotherapy of the two groups were 92.31%and 80.37%,95.11%and 82.55%,84.13%and 63.64%,respectively,and the differences between all the rates above of the two groups were statistically significant(all P<0.05). When compared to those before intervention,the growing rates of the compliance rates of examination,treatment and chemotherapy of the intervention group were 20.97%,15.33%and 23.29%, respectively,while those of control group were 14.27%,4.17%,-3.77%,respectively,the growing rates of the intervention groups were higher than those of the control groups. Conclusions Through the two?level community?based pattern of health edu?cation,the compliance rates of examination and treatment of the residents have improved,and therefore,the pattern is suitable for popularization and application in marshland and lake regions.
