Schistosomiasis Control and Elimination(GB 15976-2015)and Diagnostic Criteria for Schistosomiasis(WS 261-2006)are the only two national health criteria related to schistosomiasis control program implemented in P. R. China. The roles of criteria to guide and accelerate the transition from schistosomiasis control to elimination are concluded ,based on this system?atic review how the criteria led the implementation of the medium?and long?term national plan and provided the guidance when drafting the thirteen?five years national plan for schistosomiasis,and the suggestion to draft more criteria related to schistosomia?sis elimination program and strengthening the implementation of current criteria,so as to precisely guide the schistosomiasis elimination program in P. R. China.

Objective To observe the effect of Huoluojiangu Capsule(HJC) on anti-inflammatory experiment.Methods The anti-inflammatory experimental models were established in three kinds of rats with pleuritis,the swellen sole of the foot and the PGE_2 content in inflammatory tissues,respectively.Results The swollen reaction in the sole of foot in rats induced by egg white was lessoned with the treatment of low,middle and high dosage of HJC.Compared with the blank control group,the treatment is effective in low dosage group and evidently effective in groups of middle and high dosage after 30 min(P0.05),respectively.Compared with the blank control group,the effect of HJC on the PGE_2 content in the inflammatory tissues of middle and high dosage groups was significant(P

Objective Sporadic cases occurring in mall geographic unit could lead to extreme value of incidence due to the small population bases,which would influence the analysis of actual incidence.Methods This study introduced a method of hierarchy clustering and partitioning regionalization,which integrates areas with small population into larger areas with enough population by using Geographic Information System (GIS) based on the principles of spatial continuity and geographical similarity (homogeneity test).This method was applied in spatial epidemiology by using a data set of thyroid cancer incidence in Yiwu,Zhejiang province,between 2010 and 2013.Results Thyroid cancer incidence data were more reliable and stable in the new regionalized areas.Hotspot analysis (Getis-Ord) on the incidence in new areas indicated that there was obvious case clustering in the central area of Yiwu.Conclusion This method can effectively solve the problem of small population base in small geographic units in spatial epidemiological analysis of thyroid cancer incidence and can be used for other diseases and in other areas.

Objective: To evaluate the efficacy and safety of catheter-directed interventional therapy in patients with acute pulmonary embolism(PE). Methods: PE was diagnosed by CT pulmonary angiography(CTPA). After risk stratification, a total of 79 PE patients (age (58.9±14.9) years old)were treated with catheter-directed interventional therapy via pulmonary vessels. The changes of pulmonary hemodynamics were compared before and after treatment. The risk of complications and side effects were observed. Results: The pulmonary artery pressure was changed followed by interventional therapy. The interventional therapy significantly decreased mean pulmonary arterial pressure (mPAP) from (35.3±11.2)mmHg (1 mmHg=0.133 kPa) to (30.0±10.6)mmHg (t=8.803,P<0.05) and the echocardiographic derived right ventricular dimension to left ventricular dimension (RV/LV) ratio from 0.93±0.16 to 0.83±0.15 (t=6.868,P<0.05). The arterial partial pressure of oxygen was increased from (69.0±8.6)mmHg to (75.1±9.9)mmHg (t=8.561,P<0.05) . The oxygen saturation was also increased from (93.9±2.9)% to (95.1±1.9)% at 24 h after the treatment (t=2.621,P<0.05) . Patients were further grouped as high-risk group (n=28) and intermediate risk group (n=51). mPAP and RV/LV ratio were significantly reduced in the two subgroups (all P<0.05) and the range of reduction was more significant in the high-risk group. Five patients experienced minor bleeding complication, 3 patients suffered worsened dispone post procedure and were treated with mechanical ventilation, 1 patient died, and 1 patient developed recurrent PE. Conclusion The catheter-directed interventional therapy improves pulmonary hemodynamics and reduces load of right ventricle both in high-risk or intermediate risk PE patients, this therapy strategy is safe and effective for patients with PE.

Objective To study the application of autoregressive integrated moving average(ARIMA)model to predict the monthly reported malaria cases in China,so as to provide a reference for prevention and control of malaria. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported malaria cases of the time series of 2006-2015 and 2011-2015,respectively. The data of malaria cases from January to December,2016 were used as validation data to compare the accuracy of the two ARIMA models. Results The models of the monthly reported cases of malaria in China were ARIMA(2,1,1)(1,1,0)12 and ARIMA(1,0,0)(1,1,0)12 respectively. The comparison between the predictions of the two models and actual situation of malaria cases showed that the ARIMA model based on the data of 2011-2015 had a higher ac-curacy of forecasting than the model based on the data of 2006-2015 had. Conclusion The establishment and prediction of ARIMA model is a dynamic process,which needs to be adjusted unceasingly according to the accumulated data,and in addi-tion,the major changes of epidemic characteristics of infectious diseases must be considered.

Objective To evaluate the schistosomiasis control effect of the measures of replacing cattle with machine for cul?tivation and forbidding depasturage of livestock on marshlands in marshland and lake regions. Methods The retrospective re?view and field survey were implemented in the Jiangling and Gongan counties of Hubei Province where were implemented with the measure of replacing cattle with machine for cultivation,and Yuanjiang and Huarong counties of Hunan Province where were implemented with the measure of forbidding the depasturage of livestock on marshlands. The schistosome infection status of hu?man,cattle,and Oncomelania hupensis snails,and schistosome?infested field excreta were surveyed from 2007 to 2013. The ef?fects of the interventions were compared before and after their implementations. Results The 6 villages of Hubei Province were implemented with the measure of replacing cattle with machine for cultivation,and 7 villages of Hunan Province were imple? mented with the measure of forbidding the depasturage of livestock on marshlands. From 2007 to 2013,the schistosome infection rates of residents declined from 3.95%to 0.70%(χ2 =128.376,P<0.05),with the descend range of 82.53%. The descend ranges of the measures of replacing cattle with machine for cultivation and forbidding the depasturage of livestock on marshlands were 83.081%and 81.62%respectively,and there was no significant difference between the two measures(χ2 =0.132,P>0.05). The infection rate of cattle decreased from 3.66%in 2007 to 0.65%in 2013,and the descend range was 82.24%(χ2=13.692,P<0.05). The field excreta was surveyed in the snail breeding place in 2013. The investigated area was 157.435 hm2, and 625 samples of field feces of cattle were collected with the density of field excreta of 3.97/hm2,and the positive rate was 1.12%(7/625). The schistosome infection rate of snails and the density of infected snails decreased successively from 2007, and no infected snails were detected from 2011 to 2013. Conclusions The schistosomiasis endemic situation are decreased sig?nificantly after the interventions of replacing cattle with machine for cultivation and forbidding the depasturage of livestock on marshlands. Therefore,schistosomiasis control effect of these measures is notable in the marshland and lake regions.

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.

Photothermal therapy has the characteristics of minimal invasiveness, controllability, high efficiency, and strong specificity, which can effectively make up for the toxic side effects and tumor resistance caused by traditional drug treatment. However, due to the limited tissue penetration of infrared light, it is difficult to promote and apply in clinical practice. The eye is the only transparent tissue in human, and infrared light can easily penetrate the eye tissue, so it is expected that photothermal therapy can be used to treat fundus diseases. Here in, a new nano-platform assembled by liposome and indocyanine green (ICG) was used to treat retinoblastoma. ICG was assembled in liposomes to overcome some problems of ICG itself. For example, ICG is easily quenched, self-aggregating and instability. Moreover, liposomes can prevent free ICG from being cleared through the systemic circulation. The construction of the nano-platform not only ensured the stability of ICG in vivo, but also realized imaging-guide photothermal therapy, which created a new strategy for the treatment of retinoblastoma.

Objective:To assess the impact of reducing the mesh density on the overall volume and trueness of single-crown restora-tions.Methods:15 single-crown restorations were included,and their mesh density in 3D software was simplified by 75％,50％,25％,10％and 5％respectively.The overal volume,file size and mesh edge length of the restorations with different reduction levels were compared.Deviation analysis was conducted by curving clipping the area of the shoulder,tissue surface(except for the shoulder)and occlusal surface of the restorations and compared with those of the corresponding regions in the non-simplified restorations.Trueness was assessed using the root mean square(RMS)values for the volume and trueness of different areas.Results:Reducing the mesh den-sity did not significantly affect the overal volume of the single-crown restorations(P＞0.05),but it had a significant impact on the file size(P＜0.001),mesh edge length(P＜0.001)and the trueness of the shoulder(P＜0.001),tissue surface(except for the shoulder)(P＜0.001)and occlusal surface(P＜0.001)areas.Conclusion:Reducing the mesh density had little impact on the overall volume of the restorations but significantly affected their trueness.
