Abstract Children s emotional and behavioral problems are characterized by a relatively high incidence, concealed manifestations, and a potential correlation with an increased risk of subsequent mental disorders. These problems have a sustained impact on children s social-emotional development, learning adaptation, and peer relationships. The study reviews the main influencing factors and their mechanisms of action regarding children s emotional and behavioral problems from three levels:individual, family, and social. Under a multi-level integrated perspective, it deepens the understanding of these mechanisms and proposes that future efforts should focus on factors such as improving physical fitness, enhancing sleep, and reducing sedentary behavior. Furthermore, it suggests strengthening collaborative interventions among schools, families, and communities to promote the early prevention of childrens emotional and behavioral problems and support their healthy development.

This paper reported the diagnosis and treatment of a case of inguinal ectopic pregnancy. The patient, a 34-year-old female, had her last menstrual period on June 28, 2024. After amenorrhea, serum human chorionic gonadotropin (hCG) levels continued to rise (the highest was 13 193 U/L). However, repeated transvaginal ultrasound examinations failed to locate the implantation site of the gestational sac. Given the patient's inguinal pain, focused ultrasonography was performed in the inguinal region, revealing an ectopic pregnancy mass, which was subsequently surgically removed. Pathological analysis confirmed the diagnosis of inguinal ectopic pregnancy.

The modern Silk Road spirit advocating for win-win cooperative partnerships, aligns with the target of the “Belt and Road” Initiative, which provides new opportunities for collaboration on tropical disease control among countries along the “Belt and Road”. The modern Silk Road spirit may effectively facilitate tropical disease control programmes and improve disease control concepts and approaches through collaborative research, information sharing, infrastructure development, and joint efforts in pharmaceuticals and vaccine development; however, there are still multiple challenges that require to be overcome, including political and cultural differences, and data sharing. Therefore, countries participating in the “Belt and Road” Initiative need to work together with mutual respects, build effective collaborative mechanisms and improve communications to jointly facilitate the sustainable development of global tropical disease control programmes and cultural exchange, so as to contribute to global health and prosperities. This article discusses the contribution of the modern Silk Road spirit to facilitating global tropical disease control programmes in the context of the “Belt and Road” Initiative.

Objective:To investigate the prevalence of enterovirus 71 (EV71) and the genetic characteristics of VP1 region in common hand, foot and mouth disease (HFMD) cases in Shenzhen from 2016 to 2022.Methods:Throat swabs from mild HFMD in Shenzhen sentinel hospitals were collected from 2016 to 2022. A total of 38 EV71-positive samples were screened from these throat swabs and were sequenced. Then, the VP1 sequence of these EV71-positive samples were analyzed for their phylogenetic evolution by bioimformatics software DNAStar and MEGA 6.Results:From 2016 to 2022, the number of EV71 infections among HFMD patients in Shenzhen sentinel hospitals decreased from 136 in 2016 to 0 in 2022. The mumber of EV71 infections in 2018 and 2019 decreased by 96.3%(257/267) compared to that in 2016 and 2017. From 2020 to 2022, the number of EV71 infections decreased to 0. During this period, the EV71 vaccination rate among HFMD patients increased from 6.4% to 39.6%; Evolutionary analysis showed that the nucleotide homology and amino acid homology between 38 EV71 sample strains in Shenzhen from 2016 to 2022 were 91.8%-99.9% and 98.3%-100.0%, all belonging to the C4a subgenotype; Among them, 26 strains wene local epidemic strains, and 11 strains were imported from other provinces, with a close genetic relationship with epidemic strains in Hainan, Yunnan, Sichuan, Tianjin, Henan, Jilin, and other places. One strain from 2017 had the closest genetic relationship with the US epidemic strain OP207969-USA-2017. Further comparing the EV71 epidemic strains in Shenzhen from 2016 to 2022 and EV71 severe strains, it was found that the EV71 strains in Shenzhen carried four amino acid mutation sites related to severe condition, named R22H, K43R, I249V and T289A.Conclusions:The EV71 epidemic strains in Shenzhen from 2016 to 2022 all belong to the C4a subgenotype, and the number of EV71 infection shows a downward trend with the increase of vaccine coverage rate. At the same time, the distribution of EV71 virus strains in Shenzhen shows a significant decrease in local strains and a predominance of imported strains. There are a total of four amino acid mutation sites associated with severe cases in the EV71 sample strains in Shenzhen from 2016 to 2022. Among them, 22R and 289T are located at the N and C ends of VP1, which are related to EV71 adsorption and targeting cells. The 43R site is associated with binding ability to Annexin2 protein, which enhances cell binding ability.

Objective: To investigate the genetic characteristics of VP1 genes carried by coxsackievirus A16 strains isolated from cases of hand foot and mouth disease (HFMD) in Shenzhen during 2016 to 2017. Methods: Fecal and anal swab specimens were collected from patients with mild HFMD in four sentinel hospitals and the Institute of Pathogen Biology, Shenzhen Center for Disease Control and Prevention, China during 2016 to 2017. All specimens were tested for CVA16 viral RNA using real-time RT-PCR. The VP1 genes of 51 randomly selected CVA16 strains were amplified by RT-PCR and then sequenced using TaKaRa Biomedical Technology (Dalian). Bioinformatics software, including Mega6.02, BioEdit and DNAStar, was used for comparison and analysis of the VP1 genes. Results: CVA16 strains in Shenzhen during 2016 to 2017 mainly belonged to B1a and B1b subtypes as well as an emerging subtype B3. The epidemic of B1b subtype was found in both 2016 (28 strains) and 2017 (19 strains), while the B1a subtype (two strains) was only detected in 2017. Two B3 subtype strains were detected in 2017. The strains of B1b subtype were closely related to the strains isolated in Shanghai (JQ314149), Wenzhou (KP289416) and Beijing (KU254598), while the B1a subtype strains were closely related to the strains isolated in Kunming (JQ316639) and Tailand (GQ184139). The B3 subtype strain was an emerging CVA16 epidemic strain in mainland China. Further comparison of the CVA16 epidemic strains in Shenzhen area during 2016 to 2017 with the CVA16 strains causing severe neurological symptoms showed that two amino acid mutations (S14N and M23L) were found in VP1 protein. Conclusions The epidemic strains of CVA16 were B1b subtype in Shenzhen area in 2016. However, B1a, B1b and the emerging B3 subtype strains were prevalent in 2017. Compared with the CVA16 strains causing severe neurological symptoms, the CVA16 strains circulating in Shenzhen during 2016 to 2017 carried two amino acid mutations inVP1 protein.

Objective To analyze the genetic characteristics of VP1-VP4 genes carried by cox-sackievirus A6 (CVA6) strains isolated from severe cases of hand, foot, and mouth disease (HFMD) in Shenzhen during 2012 to 2015. -ethods The VP1-VP4 genes of CVA6 strains isolated from severe HFMD cases in Shenzhen during 2012 to 2015 were amplified and sequenced. Phylogenetic analysis was performed to analyze the VP1-VP4 genes of CVA6 isolates and sequences downloaded from GenBank by using DNASTAR6. 0 and MEGA6. 02 software packages. Results Four cases of severe HFMD were caused by CVA6 in Shenzhen during 2012 to 2015. All of the patients had the symptom of fever, skin rash and aseptic encephalitis. The CVA6 strain causing severe HFMD in 2013 shared 98. 8％-98. 9％ homology in nucleotide sequences and 99. 3％-99. 8％ in amino acid sequences with the strains isolated in 2012. Two amino acid mutations were found in the CVA6 strain isolated in 2013, which were G73E in VP2 region and S13G in VP1 region. However, the CVA6 strain isolated in 2015 only shared 95. 0％ homology in nucleotide sequences and 99. 3％ homology in amino acid sequences with the strain isolated in 2013. Six amino acid mutations were identified including E73G in VP2 region and T5A, S27N, A30V, N137S and V242I in VP1 region. The phylogenetic analysis revealed that the four CVA6 strains belong to D3 sub-genotype. The CVA6 strains causing severe cases in 2012 had the nearest genetic relationship with the strain isolated in Changsha in 2012 (KJ156349). The CVA6 strain isolated in Shenzhen in 2013 had the nearest genetic relationship with the strain isolated in Shanghai in 2013 (KJ612513). The Shenzhen CVA6 isolate in 2015 showed high similarity to Weifang CVA6 isolate in 2014 (KX752785). Conclusions All CVA6 strains causing severe HFMD ca-ses in Shenzhen during 2012 to 2015 belongs to D3 sub-genotype. Mutations of S27N and A30V in the VP1 region of the CVA6 isolate in 2015 are located in the B cell epitopes. In addition, the VP1-V242I mutation in the CVA6 strain isolated in 2015 is located in the binding site of PSGL-1 receptor. These mutations may affect the binding of CVA6 strains to the cellular receptors and their infectivity to people.

Objective? To establish a digital protection system for incontinence-associated dermatitis based on earlier prevention to reduce the incidence of incontinence-associated dermatitis. Methods? Based on the informationization of nursing platform, we run the digital protection system module of incontinence-related dermatitis based on the forward moving of the prevention gateway in Zhejiang Provincial People＇s Hospital. Through comparative study, 108 patients with incontinence and incontinence-related dermatitis from January to March 2018 were randomly selected as the pre-operation data, and 108 patients with incontinence and incontinence-related dermatitis from January to March 2019 as the post-operation data. The nurses of the two groups were observed and compared in terms of their assessment accuracy in patients＇ incontinence risk, position and Incontinence Associated Dermatitis Severity(IADS), clinical staging, and implementation of prevention strategies. Meanwhile, the incidence of incontinence-related dermatitis among all inpatients in the hospital from January to March in 2018 was compared with the same period of 2019. Results? After the operation of the digital protection system for incontinence-related dermatitis based on earlier prevention, the nursing staff's accuracy rate in the risk assessment of incontinence (χ2=38.095,P＜0.01), IADS (χ2=64.901,P＜0.01), clinical staging accuracy (χ2=42.424,P＜0.01) and the implementation of protective measures (χ2=50.000, P＜0.01) had significant statistical differences. The incidence of incontinence-related dermatitis in hospitalized patients decreased from 0.35% before operation to 0.06% after operation with statistical significance(χ2=41.031, P＜0.01). Conclusions? The operation of the digital protection system for incontinence-associated dermatitis based on earlier prevention can reduce the incidence of incontinence-associated dermatitis and improve the prevention and management competence of nursing staff.
