Methods The network laboratory for schistosomiasis diagnosis was built according to the national crite-ria in Jianglin County in 2012. Results The network laboratory for schistosomiasis diagnosis was established successfully and the operation was quiet well. Conclusion The establishment and operation of the laboratory play an important role in the real-ization of schistosomiasis elimination.

This investigation was aimed to explore whether over-expression of 27heme oxygenase-1 (HO-1) could protect bone marrow mesenchymal stem cells(BMSCs)against injury induced by high-concentration glucose. We cultured BMSCs in high-concentration glucose medium, and up-regulated or inhibited HO-1 expression in BMSCs through its agonist or inhibitor. We detected the ability of BMSCs proliferation and secretion respectively by MTT and enzyme-linked immunosorbnent assay (ELISA). Then we detected the effect of BMSCs conditions medium on proliferation and migration of human umbilical vein endothelial cells (HUVECs) through scratch experiments and transwell assay. It was found that HO-1 over-expression could not only promote BMSCs proliferation, but also promote secretion of vascular endothelial growth factor (VEGF), and could further accelerate the proliferation and migration of HUVECs. It could be well concluded that HO-1-over-expressing BMSCs can not only inhibit damage induced by high-concentration glucose, but can promote the proliferation and migration of vascular endothelial cells through paracrine as well. The result indicated that HO-1-over-expressing BMSCs played an important role in the treatment of diabetic vascular complication.

Objective To evaluate the efficacy of routinely used pattern for schistosomiasis diagnosis in lake and marshland regions. Methods A historically heavy endemic village of schistosomiasis named Jinggan Village from Jiangling County was se?lected for field survey. The residents aged 6?65 years were screened by indirect hemagglutination assay(IHA)and dipstick dye immunoassay(DDIA)in parallel. The serological positives were examined by Kato?Katz technique and miracidium hatching technique to determine the infection of schistosome. The consistency of the two serological methods was evaluated. In addition , the schistosome infection rates were estimated according to the 3 detection patterns namely IHA,DDIA,IHA+DDIA combined with the etiologic examination. Results A total of 530 individuals were examined by the serological tests. The positive rate of DDIA was 46.98%(249/530),significantly higher than that of IHA(28.49%,151/530)(χ2=59.55,P<0.01). Totally 279 in?dividuals were serological positives determined by IHA or DDIA,while 252 of them were detected by stool examination,and 22 cases were determined as parasitological positives,while 7 and 3 cases were diagnosed as antibody negatives by IHA and DDIA,respectively. The estimated infection rates determined by IHA,DDIA,IHA plus DDIA combined with stool examination were 3.14%,3.97%、4.60%,respectively. Conclusions Under the condition of endemic situation becoming more and more waning,the current routinely used pattern for schistosomiasis detection may lead to missed diagnosis. So,more sensitive and ef?fective diagnostic tools or appropriate detection patterns need to be explored.

Objective To understand the spatial distribution characteristics of wild feces in schistosomiasis endemic areas of Jiangling County,Hubei Province and further explore the source of infection efficiently,so as to provide the evidence for the development of corresponding monitoring and response technology. Methods In 2011,the fresh wild feces were investigated every two months in the selected 15 villages by the severity of historical endemic in Jiangling County. The schistosome miracidi-um hatching method was used to test the schistosome infection of the wild feces. The descriptive analysis and spatial analysis were used for the description of the spatial distribution of the wild feces. Results Totally 701 wild feces samples were collected with the average density of 0.0556/100 m2,and the positive rate of the wild feces was 11.70%(82/701). The results of the re-gression analysis showed a positive spatial correlation between the positive rate of wild feces and the rate of human infection,the area with infected Oncomelania hupensis and the number of fenced cattle,and the corrected R2 of the model was 0.58. Conclu-sion The infection rate of wild feces is positively correlated with the rate of human infection,area with infected O. hupensis and number of fenced cattle in space in Jiangling County,so the prevention and control measures could be conducted according to the spatial distribution of the positive wild feces.

Cystic echinococcosis (CE), a zoonotic disease caused by Echinococcus granulosus at the larval stage, predominantly develops in the liver and lungs of intermediate hosts and eventually results in organ malfunction or even death. The interaction between E. granulosus and human body is incompletely understood. Exosomes are nanosized particles ubiquitously present in human body fluids. Exosomes carry biomolecules that facilitate communication between cells. To the best of our knowledge, the role of exosomes in patients with CE is not reported. Here, we isolated exosomes from the sera of patients with CE (CE-exo) and healthy donors and subjected them to liquid chromatography-tandem mass spectrometry analysis. Proteomic analysis identified 49 proteins specifically expressed in CE-exo, including 4 proteins of parasitic origin. The most valuable parasitic proteins included tubulin alpha-1C chain and histone H4. And 8 proteins were differentially regulated in CE-exo (fold change>1.5), as analyzed with bioinformatic methods such as annotation and functional enrichment analyses. These findings may improve our understanding about the interaction between E. granulosus and human body, and may contribute to the diagnosis and prevention of CE.

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.

This article reported a male neonate with lethal mitochondrial trifunctional protein deficiency (MTPD) caused by compound heterozygous variations in the HADHB gene. The patient presented with poor milk intake complicated by abnormal myocardial enzymes within 24 h after birth and was transferred to the Children's Hospital of Nanjing Medical University on day 4. Physical examination revealed no obvious abnormalities on admission. Laboratory examination showed increased creatine kinase isoenzyme and cardiac troponin levels, and electrocardiogram suggested sinus tachycardia and low QRS voltage in limb leads. Blood screening for metabolic abnormalities showed high levels of tetradecenyl carnitine and various 3-hydroxycarnitines. Heterozygous mutations of c.739C>T(p.Arg247Cys) and c.607C>T(p.Arg203Ter,272) were detected in the HADHB gene in the boy, which were pathogenic variants included in the Human Gene Mutation Database. Followed up to three months of age, the boy was readmitted to hospital due to poor milk intake for one week and poor response for 2 d after catching a cold. After admission, he quickly developed multiple organs dysfunction such as heart failure and respiratory failure, and then died. Lethal MTPD is rare with no effective treatment and poor prognosis. Lethal MTPD should be highly suspected when unexplained cardiomyopathy, hypoglycemia, acidosis and other metabolic abnormalities appear in the neonatal period, and an early diagnosis could be confirmed with genetic testing in the neonatal period.

The incidence of brain metastases in patients with non-small cell lung cancer (NSCLC) has increased as a result of improved local control rate and survival rate. Prophylactic cranial irradiation (PCI) has been proven to reduce the incidence of brain metastases and improve survival rate in patients with NSCLC. However, the value of PCI for NSCLC is still controversial. This paper reviews the progress of the efficacy and adverse reactions after PCI treatment for patients with NSCLC.
