Objective To understand the schistosomiasis prevention knowledge of middle school students from areas with dif-ferent endemic levels in Hubei Province. Methods The schistosomiasis endemic regions were divided into transmission con-trolled areas and endemic controlled areas in Hubei Province,middle school students from different types of areas were selected through stratified randomized cluster sampling and were investigated by questionnaire. Results A total of 3 204 students were se-lected and investigated. The awareness rate of schistosomiasis prevention and control knowledge among the students ranged from 65.1%-90.3%. Overall,the students from endemic controlled areas had higher knowledge rates of all the items than those from transmission controlled areas(all P<0.05). The middle school students acquired schistosomiasis prevention knowledge mainly from the teachers,parents,doctors and schistosomiasis staff. Conclusion Health education to students should adopt different ways targeting at different endemic levels in the future.

OBJECTIVE:To compare the anti-inflammation,analgesia effects of decoctions extracted from Aconiti lateralis with different leaf shapes(dahua leaf,xiaohua leaf)from different producing areas(Jiangyou,Butuo). METHODS:Animals were randomly divided into blank group(distilled water),positive group,groups of Aconiti lateralis with dahua,xiaohua leaf from Ji-angyou,groups of Aconiti lateralis with dahua,xiaohua leaf from Butuo(with dose of 5 g/kg,calculated by crude drug). The an-ti-inflammation effect of decoctions extracted from Aconiti lateralis with different variety sources and leaf shapes was investigated by xylene-induced ear swelling test (n=12) in mice and egg white-induced toe swelling test (n=10) in rats (positive drug was Dexamethasone acetate tablet,0.005 g/kg). And its analgesic effect was investigated by acetic acid-induced writhing body reaction test(n=12)and hot-plate-induced pain test(n=12)in mice(positive drug was Morphine hydrochloride tablet,0.0025 g/kg). RE-SULTS:The decoctions extracted from Aconiti lateralis with dahua,xiaohua leaf from Butuo and xiaohua leaf from Jiangyou can significantly reduce the ear swelling degree(P<0.01). The decoctions extracted from Aconiti lateralis with dahua leaf from Jiangy-ou and Butuo can significantly decrease the toe swelling degree after 6 h of medication(P<0.05). And decoctions extracted from Aconiti lateralis with xiaohua leaf from Butuo can significantly reduce the number of writhing body in mice with acetic acid-in-duced pain and prolong the pain threshold of mice with hot-plate-induced pain (P<0.05 or P<0.01). CONCLUSIONS:Aconiti lateralis with dahua and xiaohua leaf from Butuo and with xiaohua leaf from Jiangyou show better anti-inflammation effect,and Aconiti lateralis with xiaohua leaf from Butuo shows better analgesic effect.

OBJECTIVE:
To explore the genetic basis for a child with supravalvular aortic stenosis.
METHODS:
The child and his parents were subjected to conventional G-banding karyotyping, array comparative genomic hybridization (aCGH) and multiplex ligation-dependent probe amplification (MLPA) analysis.
RESULTS:
No karyotypic abnormality was detected in the child and his parents. aCGH has identified a de novo 278 kb deletion encompassing the ELN gene in 7q11.23, which overlapped with the critical region of Williams-Beuren syndrome (WBS). MLPA has confirmed above findings.
CONCLUSION
The proband was diagnosed with atypical WBS. Deletion of the ELN gene may predispose to supravalvular aortic stenosis in the proband.

OBJECTIVETo analyze the molecular mechanism and prognosis of a child with aortic stenosis and thumb aplasia.
METHODSThe karotypes of the child and his parents were analyzed with routine G-banding. Their genomic DNA was also analyzed with array comparative genomic hybridization(aCGH) for chromosomal duplications/deletions.
RESULTSNo karyotypic abnormality was detected at cytogenetic level for the child and his parents. aCGH identified a de novo 5.86 Mb deletion at 2q22.3-q23.3 in the child.
CONCLUSIONThe child was diagnosed with 2q23.1 microdeletion syndrome. MBD5 may be the key gene for the 2q23.1 microdeletion syndrome.

OBJECTIVE:
To carry out genetic testing and prenatal diagnosis for a family affected with Duchenne muscular dystrophy (DMD).
METHODS:
Multiplex ligation dependent probe amplification (MLPA) was used to detect potential deletion and duplication of the Dystrophin gene. Haplotype analysis was performed using five short tandem repeat polymorphism loci (3'-STR, 5'-STR, 45-STR, 49-STR, 50-STR of the DMD gene.
RESULTS:
A same deletional mutation (exons 51-55) of the DMD gene was detected in two brothers but not in their mother. The patients and fetus have inherited different haplotypes of the Dystrophin gene from their mother, suggesting that the fetus was unaffected.
CONCLUSION
The mother was very likely to harbor germline mosaicism for the Dystrophin gene variant. Genetic testing of peripheral blood samples cannot rule out germline mosaicism in the mother. Prenatal diagnosis should be provided for subsequent pregnancies in this family.

OBJECTIVE:
To explore the molecular mechanism of a girl with developmental delay and intellectual disability.
METHODS:
Chromosomal karotypes of the child and her parents were analyzed with routine G-banding method. Their genomic DNA was also analyzed with array comparative genomic hybridization (aCGH) for chromosomal duplications/deletions.
RESULTS:
No karyotypic abnormality was detected in the child and her parents, while aCGH has identified a de novo 3.37 Mb deletion at 17p11.2 in the child.
CONCLUSION
The child was diagnosed with Smith-Magenis syndrome, for which RAI1 may be the causative gene.

OBJECTIVE:
To explore the genetic basis for a pedigree affected with Bartter's syndrome (BS).
METHODS:
Panel-based next-generation sequencing (NGS) was carried out to detect mutation in BS-related genes SLC12A1, KCNJ1, BSND and CLCNKB. Sanger sequencing of MAGED2 gene and chromosomal microarray analysis (CMA) were also performed on the patient. Suspected mutation was validated in her family members.
RESULTS:
No pathogenic mutation was detected by NGS, while a 0.152 Mb microdeletion at Xp11.21 (54 834 585-54 986 301) was found in the male fetus, which removed the entire coding region of the MAGED2 gene. His mother was a heterozygous carrier of the deletion. His father and sister did not carry the same deletion.
CONCLUSION
The loss of the MAGED2 gene may underlie the BS in this pedigree.

Objective To understand the spatial and temporal distribution of HIV/AIDS in Hubei province,and provide scientific evidence for the prevention and control of AIDS.Methods GeoDa software was used for autocorrelation analysis,SatScan 9.2 software was used for statistical analysis of spatial scanning,and finally geographic information system was used for visualization.Results A total of 6 952 HIV/AIDS cases were reported during 2010-2013 in Hubei,and the spatial autocorrelation analysis showed that Global Moran's I index was 0.266 (P<0.05),indicating that there was a positive spatial autocorrelation of HIV/AIDS.Global Moran's I index increased year by year (P< 0.05),indicating that the increased spatial aggregation of HIV/AIDS during 2010-2013.The local Moran's I index showed that "high-high" clustering areas were in Wuhan,and the number of "high-high" clustering areas increased during 2010-2013.Moreover,the "high-high" clustering areas expanded from Wuhan to surrounding areas.Spatial and temporal scan analysis revealed that 19 counties in Wuhan,Huangshi,Ezhou,Xianning with a radius of 60.01 km (LLR=625.14,RR=3.23) were the main spatial and temporal clustering area during 2012-2013.Conclusion The spatial changes of HIV/AIDS seemed to be regular from 2010 to 2013 in Wuhan,spatial correlation at provincial level decreased and the "high-high" clustering areas gradually expanded from Wuhan to surrounding areas,indicating that it is necessary to strengthen the AIDS prevention and control in these areas in Hubei.
