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 prevalence and influential factors of chronic respiratory system diseases among resi-dents over 1 5 years old in Hubei province and provide evidence for disease prevention.Methods During October to November in 2013,through stratified cluster sampling,we sampled 20 cities or counties.The survey included the the general condition of family, individual,chronic diseases.Results A total of 28 563 residents answered the questionnaire and 423 of them reported chronic re-spiratory system diseases by themselves.The prevalence rate was 14.8‰.These included 229 cases with COPD(54.1%),44 cases with asthma(10.4%),35 cases with chronic pharyngolaryngitis(8.3%)and 1 1 5 cases with other chronic respiratory system disea-ses(27.2%).In urban and rural area,the prevalence rate were 13.6‰ and 1 5.7‰ respectively.Multivariate logistic analysis showed that gender,age,economic status and medical insurance are influential factors of chronic respiratory system diseases.Conclusion Prevalence rate of chronic respiratory system diseases among residents over 1 5 years old in Hubei province was slightly increased and disease control measures should be brought out.

Objective:To investigate the effect of Norcantharidin(NCTD)on the apoptosis of human ovarian cancer SKOV3 cells and its mechanism.Methods:Human ovarian cancer SKOV3 cells were cultured in vitro and treated with 52 μmol/L NCTD.The SKOV3 cells were divided into the control group and NCTD group(52 μmol/L).The morphological changes of SKOV3 cells were observed under an inverted microscope,and the changes of nucleus were observed under a fluorescence microscope.The changes of mitochondrial membrane potential were detected by flow cytometry after drug treatment for 24 h.Western blot was used to detect the expression levels of apoptosis-related proteins Bax,Bcl-2 and Wnt/β-catenin signaling pathway-related protein β-catenin in SKOV3 cells after drug treatment for 24 h.Result:Compared with that in the control group,NCTD inhibited the proliferation of SKOV3 cells,reduced mitochondrial membrane potential,induced apoptosis of SKOV3 cells,increased the expression of Bax protein,decreased the expression of Bcl-2 protein and β-catenin.Conclusion:NCTD-induced apoptosis of ovarian cancer SKOV3 cells may be related to the regulation of Wnt/β-catenin signaling pathway.

We report a case of a male patient who developed persistent fever and central nervous system symptoms after eating raw snails for 10 days. The patient was diagnosed with Angiostrongyliasis depended on the clinical presentation, epidemiological history, and etiological results. The patient recovered after receiving albendazole anthelmintic and dexamethasone anti-inflammatory therapy. This article incorporates literature review to sort out the diagnosis and treatment of this patient, in order to provide feasible reference for clinicians.

Objective To analyze the risk factors of unplanned reoperation and construct a nomogram-based risk prediction model to identify high-risk patients,so as to provide a basis for perioperative manage-ment to reduce the rate of reoperation.Methods A total of 880 patients with underwent unplanned reopera-tion between 2018 and 2021 were included as the unplanned reoperation group.Using propensity score matc-hing,2640 patients were matched in a 1∶3 ratio to form the control group.Potential risk factor indicators were collected and subjected to univariate analysis.Significant indicators were then selected for multivariable logistic regression analysis to construct the risk prediction model.The predictive value of the model was evalu-ated.Results For unplanned reoperation,The number of complications 3-5 (OR=1.84),the number of complications 6-10 (OR=2.94),combined with maligant tumor (OR=1.75),combined with end-stage renal disease (OR=1.92),major surgery grade 3 (OR=4.27),major surgery grade 4 (OR=7.26),and incision grade Ⅰ,Ⅱ,Ⅲ (OR=2.18,1.97,6.85) were independent factors (P<0.05).The model passed the calibra-tion degree test,and the area under ROC curve (AUC) was 0.715,indicating good model differentiation.Con-clusion A risk prediction model based on risk factors can help identify high-risk populations for unplanned reoperation and suggest corresponding measures for prevention.

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.
