Echinococcosis is a common zoonotic disease in livestock; the type with the highest incidence is cystic
echinococcosis (CE). In clinical management, patients with CE of the liver in which the cyst wall is calcified
have been found to have better prognoses than those without calcification. In this study, we collected
calcified and uncalcified cyst wall tissue from patients with hepatic CE and observed significant changes
in the expression of 2336 messenger ribonucleic acids (mRNAs), 178 long noncoding RNAs (lncRNAs),
210 microRNAs (miRNAs), and 33 circular RNAs (circRNAs) using high-throughput sequencing (HTS).
Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of
differentially expressed RNAs (DERNAs: DEmRNAs, DElncRNAs, DEmiRNAs, and DEcircRNAs) were
performed to explore these RNAs’ potential biological functions and signaling pathways. Ultimately,
the results of hematoxylin and eosin (H&E) and terminal deoxynucleotidyl transferase deoxyuridine
triphosphate (dUTP) nick end labeling (TUNEL) staining confirmed the correlation between calcification
and apoptosis of the cyst wall. In summary, this study was an initial exploration of the molecular-biological
mechanism underlying spontaneous calcification of the hydatid cyst wall, and it provides a theoretical
basis for exploring new targets for drug treatment in CE.

Objective: To investigate the value of inflammation,coagulation and nutrition markers in predicting the failure of prosthesis removal and antibiotic-loaded bone cement spacer implantation for treatment of periprosthetic joint infection(PJI). Methods: A retrospective study was conducted on 70 patients who undertook prosthesis removal and antibiotic-loaded bone cement spacer implantation due to PJI from June 2016 to October 2020 in the Department of Orthopedics,Henan Provincial People's Hospital. There were 28 males and 42 females,aged (65.5±11.9) years (range: 37 to 88 years). Patients were divided into two groups as the successful group and the failed group depended on whether reinfection occurred after prosthesis removal and antibiotic-loaded bone cement spacer implantation at the last follow up. Patient demographics,laboratory values (C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),ESR and CRP ratio (ESR/CRP),white blood cell count(WBC),platelet count(PLT),hemoglobin(HB),total lymphocyte count(TLC),albumin、fibrinogen(FIB),CRP and albumin ratio (CAR),prognostic nutritional index(PNI)),and reinfection rates were assessed. Comparison between groups was conducted by the independent sample t test or χ2test. Receiver operating characteristic (ROC) curve was plotted,and the area under the curve (AUC),optimal diagnostic threshold,sensitivity,and specificity were analyzed to predict the failure of prosthesis removal and antibiotic-loaded bone cement spacer implantation. Results: All patients were followed up for at least two years,and the follow-up time was (38.4±15.2) months (range: 24 to 66 months). Fifteen patients suffered failure after prosthesis removal and antibiotic-loaded bone cement spacer implantation,while the other 55 patients succeeded. The overall failure rate of prosthesis removal and antibiotic-loaded bone cement spacer implantation in PJI treatment was 21.4%. Level of preoperative CRP ((35.9±16.2)mg/L),PLT ((280.0±104.0)×109/L) and CAR (1.3±0.8) in successful group were lower than CRP ((71.7±47.3)mg/L),PLT ((364.7±119.3)×109/L) and CAR (2.5±2.0) in failed group (all P<0.05).Whereas,level of preoperative ESR/CRP (3.3±3.1), Albumin ((35.3±5.2)g/L) and PNI (43.6±6.2) in successful group were higher than ESR/CRP (1.6±1.4),Albumin ((31.3±4.8)g/L) and PNI (39.2±15.1) in failed group (all P<0.05). AUC of ROC curve,optimal threshold value,sensitivity and specificity of CRP,ESR/CRP, PLT, Albumin,CAR and PNI for the predicting failure of prosthesis removal and antibiotic-loaded bone cement spacer implantation were 0.776(95%CI:0.660 to 0.867),35.4 mg/L,86.7%,67.3%;0.725(95%CI:0.605 to 0.825),1.0,60.0%,78.2%;0.713(95%CI:0.593 to 0.815),253,93.3%,47.3%;0.721(95%CI:0.601 to 0.822),35.7,93.3%,49.1%;0.772(95%CI:0.656 to 0.863),1.1,86.7%,67.3%;0.706(95%CI:0.585 to 0.809),45.7,100%,41.8% respectively. Conclusion: In patients with PJI,CRP>35.4,ESR/CRP≤1.0 and CAR>1.1 could predict the failure of prosthesis removal and antibiotic-loaded bone cement spacer implantation.

OBJECTIVE:
To identify the spatial distribution pattern of Oncomelania hupensis spread in Hubei Province, so as to provide insights into precision O. hupensis snail control in the province.
METHODS:
Data pertaining to emerging and reemerging snails were collected from Hubei Province from 2020 to 2022 to build a spatial database of O. hupensis snail spread. The spatial clustering of O. hupensis snail spread was identified using global and local spatial autocorrelation analyses, and the hot spots of snail spread were identified using kernel density estimation. In addition, the correlation between environments with snail spread and the distance from the Yangtze River was evaluated using nearest-neighbor analysis and Spearman correlation analysis.
RESULTS:
O. hupensis snail spread mainly occurred along the Yangtze River and Jianghan Plain in Hubei Province from 2020 to 2022, with a total spread area of 4 320.63 hm2, including 1 230.77 hm2 emerging snail habitats and 3 089.87 hm2 reemerging snail habitats. Global spatial autocorrelation analysis showed spatial autocorrelation in the O. hupensis snail spread in Hubei Province in 2020 and 2021, appearing a spatial clustering pattern (Moran's I = 0.003 593 and 0.060 973, both P values < 0.05), and the mean density of spread snails showed spatial aggregation in Hubei Province in 2020 (Moran's I = 0.512 856, P < 0.05). Local spatial autocorrelation analysis showed that the high-high clustering areas of spread snails were mainly distributed in 50 settings of 10 counties (districts) in Hubei Province from 2020 to 2022, and the high-high clustering areas of the mean density of spread snails were predominantly found in 219 snail habitats in four counties of Jiangling, Honghu, Yangxin and Gong'an. Kernel density estimation showed that there were high-, secondary high- and medium-density hot spots in snail spread areas in Hubei Province from 2020 to 2022, which were distributed in Jingzhou District, Wuxue District, Honghu County and Huangzhou District, respectively. There were high- and medium-density hot spots in the mean density of spread snails, which were located in Jiangling County, Honghu County and Yangxin County, respectively. In addition, the snail spread areas negatively correlated with the distance from the Yangtze River (r = -0.108 9, P < 0.05).
CONCLUSIONS
There was spatial clustering of O. hupensis snail spread in Hubei Province from 2020 to 2022. The monitoring and control of O. hupensis snails require to be reinforced in the clustering areas, notably in inner embankments to prevent reemerging schistosomiasis.

5.Cross - species regulation and underlying mechanisms of parasite - derived non-coding RNAs: a review.
Chinese Journal of Schistosomiasis Control 2023;35(5):529-533
Parasite-derived non-coding RNAs (ncRNAs) not only contribute to life activities of parasites, and microRNA (miRNA), long non-coding RNA (lncRNA), and circular RNA (circRNA) may generate a competitive endogenous RNA (ceRNA) regulatory network with host miRNAs and mRNAs via extracellular vesicles, thereby participating in infection and pathogenic processes. This article presents an overview of characterizing ncRNAs derived from parasites and the cross-species regulatory role of parasite-derived ncRNAs in host gene expression and its underlying mechanisms.

6.Study on the association between occupational noise exposure and cardiovascular diseases.
Chinese Journal of Industrial Hygiene and Occupational Diseases 2021;39(7):555-557
Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

The aim of this paper was to investigate the mechanism of the active peptide DP17 of Eupolyphaga steleophaga in the treatment of hyperlipidemia rats. HPLC and MADIL-TOF/TOF-MS were used for the amino acid sequence analysis and solid-phase synthesis on the active peptide of E. steleophaga which were obtained by biomimetic enzymatic hydrolysis, separation and purification. The hyperlipidemia model was established by feeding with high-fat diet.Twenty days later, the rats in the blank group and the model group were given the saline and the rats in remaining groups were given the corresponding drugs by oral administration. After administration for 4 weeks, the levels of triglyceride(TG), total cholesterol(TC) and low density lipoprotein(LDL) in serum, the levels of TG, TC, adenosine monophosphate(AMP), adenosine triphosphate(ATP) in liver tissues and TG in feces were detected, respectively. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of liver tissues. The Real-time fluorescence quantitative PCR method was used to detect the expression of acetyl coa carboxylase(ACC) and hydroxymethylglutaryl-coa reductase(HMGCR) mRNA in liver tissues. The expression of mammalian target of rapamycin(mTORC1) protein and adenosine 5'-monophosphate-activated protein kinase(AMPK) in liver tissues were detected by Western blot. The analysis showed that the amino acid sequence of active peptide from E. steleophaga was DAVPGAGPAGCHPGAGP(DP17). The results of pharmacological experiments showed that after oral administration of DP17 in rats, the levels of TG, TC and LDL in serum as well as TG and TC levels in liver tissues were significantly decreased(P<0.05), while the levels of AMP, ATP in liver tissues and TG content in feces were significantly increased(P<0.05); the liver steatosis of rats was significantly relieved; the expression of ACC, HMGCR mRNA and mTORC1 protein in liver tissues were significantly reduced, while the expression of AMPK phosphorylated protein was significantly increased(P<0.05). DP17, the active peptide of E. steleophag can significantly reduce lipid accumulation in liver tissues, and it may play a role in reducing blood lipids by regulating the energy metabolism balance in the body and activating AMPK/mTOR signaling pathway.

Risk factors for hypertension consist of lifestyle and genetic factors. Family history and twin studies have yielded heritability estimates of BP in the range of 34-67%. The most recent paper of BP GWAS has explained about 20% of the population variation of BP. An overestimation of heritability may have occurred in twin studies due to violations of shared environment assumptions, poor phenotyping practices in control cohorts, failure to account for epistasis, gene-gene and gene-environment interactions, and other non-genetic sources of phenotype modulation that are suspected to lead to underestimations of heritability in GWAS. The recommendations of hypertension guidelines in major countries consist of the following elements: weight reduction, a healthy diet, dietary sodium reduction, increasing physical activity, quitting smoking, and moderate alcohol consumption. The hypertension guidelines are mostly the same for each country or region, beyond race and culture. In this review, we summarize gene-environmental interactions associated with hypertension by describing lifestyle modifications according to the hypertension guidelines. In the era of precision medicine, clinicians who are responsible for hypertension management should consider the gene-environment interactions along with the appropriate lifestyle components toward the prevention and treatment of hypertension. We briefly reviewed the interaction of genetic and environmental factors along the constituent elements of hypertension guidelines, but a sufficient amount of evidence has not yet accumulated, and the results of genetic factors often differed in each study.

The excessive consumption of sugar-sweetened beverages is a public health concern worldwide. Several clinical trials examining the effects of consuming sucrose or high-fructose corn syrup demonstrated the link between this consumption and increased risk factors for cardiometabolic diseases. In this issue of Environmental Health and Preventive Medicine, Li et al. examined the sugar-sweetened beverage consumption among undergraduate students and evaluated the relationship between this consumption and the "late" chronotype, sleep duration, and weight increase. They concluded that the sugar-sweetened beverage intake might mediate the associations among sleep duration, late chronotype, and weight gain and that the intake of sugar-sweetened beverages in the evening may be a risk factor for the development of overweight/obesity. A systematic review and meta-analysis of prospective cohort studies and randomized controlled trials provided evidence that the consumption of sugar-sweetened beverages promotes weight gain in both children and adults. The World Health Organization guideline highly recommends reducing the intake of sugars to less than 10% of one's total energy intake. The Dietary Approaches to Stop Hypertension diet and the Mediterranean diet were shown to help individuals refrain from sweets and sugar-containing beverages. A global evaluation revealed how much disability during accumulated lifetime hours is due to sugar-sweetened beverages. Interventions are necessary, but many individuals find it quite difficult to reduce or eliminate their high intake of sugar-sweetened beverages. The taxation of sugar-sweetened beverages was demonstrated to have a significant positive influence on individuals' planned purchases and the probability of the purchase of healthy beverages. Western countries are working on the social regulation of sugar-sweetened beverages, but Japan has not implemented any similar regulations. The social regulation of sugar-sweetened beverages is necessary to stop the increase of diabetes morbidity and the increase in dementia that often accompanies this morbidity.

Objective: To estimate the serotype and age-specific hospitalization burden associated with hand, foot and mouth disease (HFMD) in Anhua county of Hunan province, between October 2013 and September 2016. Methods: We collected hospitalization records of HFMD patients from 6 virological surveillance hospitals, and reimbursement records through new rural cooperative medical system from 23 township health centers to estimate the age-specific hospitalization burden of HFMD in Anhua. Combined with the results of virological surveillance, the serotype-specific hospitalization burden of HFMD in Anhua, was estimated. Results: During the three years, it was estimated that 3 541 clinical diagnosed HFMD cases, including 3 146 laboratory-confirmed HFMD cases, were hospitalized in Anhua, but only one was diaguosed as being severe. The estimated average hospitalization rate was 723/100 000(95%CI: 699/100 000-747/100 000) for clinical diagnosed HFMD and 642/100 000 (95%CI: 620/100 000-665/100 000) for laboratory-confirmed HFMD between October 2013 and September 2016. The cases caused by Cox A16 (208/100 000) and Cox A6 (202/100 000) had higher hospitalization rates compared with the cases caused by EV71 (130/100 000), Cox A10 (38/100 000) and other enterovirus (64/100 000), and the difference was statistically significant (P<0.001). HFMD-associated hospitalization rates peaked in children aged 1 year (3 845/100 000), and then decreased with age. Compared with the hospitalized HFMD caused by EV71 and Cox A16, Cox A6-associated hospitalizations mainly occurred in younger age groups (P<0.001). Conclusion: Our study revealed a substantial hospitalization burden associated with mild HFMD caused by EV71, Cox A16, Cox A6 and Cox A10, especially in young children, in Anhua.
