Abstract
Isolated orbital floor fractures are more frequent due to low bone thickness (2 mm). The aim of this study was to conduct a retrospective epidemiological analysis on these fractures, investigating demographic variables and fractures' features and their statistical correlation. A total of 120 patients with isolated orbital floor fracture, admitted at the Maxillofacial Surgery Unit of University of Naples Federico II, from 2010 to 2022 were enrolled in the study. Patients were evaluated for age, sex, smoke, comorbidities, post-traumatic clinical manifestation,s and defect side and size. Statistical analysis was conducted using the Pearson regression coefficient (r). The fractures were more frequent in men (male:female 2.2:1) because of road accidents (30% of cases). The average age was 48 years. Enophthalmos, diplopia and ocular motility anomalies were observed in 31%, 23% and 21% of cases, respectively. Statistical analysis revealed that age was related to fracture area; in particular, older patients showed larger fractures (p < 0.001). Interpersonal violence and traffic accidents were related to younger age (p < 0.001). Data analysis revealed that isolated orbital floor fractures are more frequent in young men (<40 years) because of road accidents or interpersonal violence. There is a statistical correlation between fracture area and patient age; in particular, older age corresponds to larger defects.

Abstract
BACKGROUND Echinococcosis is prevalent in 9 provinces in Western and Northern China. An epidemiological survey of echinococcosis in 2012 and 2016 showed cases of echinococcosis in Yunnan Province. AIM To understand the spatial distribution and epidemiological characteristics of echinococcosis in Yunnan for the prevention and control of echinococcosis and to reduce the risk of infection in Yunnan Province. METHODS Based on the China Information System for Disease Control and Prevention (CISDCP), echinococcosis cases reported from 36 hospitals and 34 Centers for Disease Control were investigated and epidemiologically analyzed from 2021 to 2022. The exclusion criteria included suspected cases, same case only counted once and cases not from Yunnan. A total of 705 cases were investigated, of which 397 cases were suitable for statistical analysis. In these 397 cases, epidemiological investigation was tracked in 187 cases. All data were inputted using double entry in the Excel database, with error correction by double-entry comparison. The data on echinococcosis cases in Yunnan Province were analyzed by ArcGIS 10.1 software to generate a density map of echinococcosis distribution. All statistical analyses were conducted using SPSS 17.0, including the chi-square test, linear regression test and logistic univariate and multivariate regression analyses. RESULTS A total of 397 cases were found in 89 counties in Yunnan Province. The number of cases in the top three prefectures were Dali (38.1%), Diqing (10.1%), and Kunming (8.3%), and the top five counties were Jianchuan (9.1%), Shangri La (8.3%), Eryuan (7. 6%), Heqing (6.9%), and Dali Districts (5.0%). There were significant differences between the different areas. The case reporting rate by CISDCP (33.8%) was low; the first case was reported by CISDCP in 2002, and the highest number of cases was 50 (2017). Confirmed and clinical cases accounted for 62.5% and 37.5%, respectively. However, 90.9% of the cases of hydatid disease were reported by the hospital system, and only 9.1% of the cases of hydatid disease were found in the community through active screening. The difference between the two methods of case detection was statistically significant. Most of the cases of echinococcosis were found in farmers/herdsmen (75.1%) and students (9.1%). In addition, Han (43.6%) and Bai (26.2%) had a higher incidence of infection than other nationalities, and the liver (87.7%) and lung (6.8%) were the most common sites of cyst formation. Among the analyzed cases, 187 were epidemiologically analyzed and the clinical symptoms were not obvious in the early stage in 47.1% of cases. The results of logistic regression analysis showed that the age group, education level, presence of dogs in the family (either previously or currently), and handwashing (occasionally or not) were factors related to echinococcosis infection. 55.6% of cases were in endemic areas, and 44.4% of cases were in non-endemic areas. Among 83 cases in non-endemic areas, only 4 cases had been to endemic areas and had a history of living, working, travelling, or hunting in echinococcosis epidemic areas. CONCLUSION Cases of echinococcosis were reported throughout the entire Yunnan province, with the majority distributed in Western Yunnan, suggesting that echinococcosis control should be strengthened in this area. We suggest that an epidemiological investigation should be carried out in the future, based on the clues from newly discovered cases in hospitals or from the CISDCP. The newly discovered cases in the hospital provided clues to comprehensively determine the location of cases and where epidemic spot investigation should be conducted.

Abstract
The 2022 FIFA World Cup (FIFA-WC) held in Qatar presented unique challenges, given the potential for rapid transmission of coronavirus disease 2019 (COVID-19) among over 1.4 million international fans attending the event. This study aimed to investigate the impact of the FIFA-WC 2022 on COVID-19 cases, deaths, and reproduction rate (R0) in Qatar. Additionally, it sought to understand the implications of hosting large-scale events during a pandemic without COVID-19 restrictive measures, providing critical insights for future decision-making. Data from "Our World in Data" were analysed for three distinct periods: one week before the FIFA-WC (week-preWC), the four weeks of the event (week-1WC to week-4WC), and one week after (week-postWC). The results revealed a significant increase in COVID-19 cases during week-3WC and week-4WC (compared to week-preWC) in Qatar, followed by a subsequent decrease during the week-postWC. Notably, Qatar experienced a more pronounced surge in positive cases than the global trend. Regarding COVID-19-related deaths, Qatar's peak occurred during week-2WC, while globally deaths peaked from week-3WC to week-postWC. Nevertheless, Qatar's death toll remained relatively low compared to the global trend throughout the event. The findings highlight that the FIFA-WC 2022 in Qatar demonstrated the feasibility of organizing large-scale sporting events during a pandemic with appropriate measures in place. They emphasize the importance of high vaccination coverage, continuous monitoring, and effective collaboration between event organizers, healthcare authorities, and governments. As such, the event serves as a valuable model for future gatherings, underlining the significance of evidence-based decision-making and comprehensive public health preparedness.

Abstract
The effect of environmental and socioeconomic conditions on the global pandemic of COVID-19 had been widely studied, yet their influence during the early outbreak remains less explored. Unraveling these relationships represents a key knowledge to prevent potential outbreaks of similar pathogens in the future. This study aims to determine the influence of socioeconomic, infrastructure, air pollution, and weather variables on the relative risk of infection in the initial phase of the COVID-19 pandemic in China. A spatio-temporal Bayesian zero-inflated Poisson model is used to test for the effect of 13 socioeconomic, urban infrastructure, air pollution, and weather variables on the relative risk of COVID-19 disease in 122 cities of China. The results show that socioeconomic and urban infrastructure variables did not have a significant effect on the relative risk of COVID-19. Meanwhile, COVID-19 relative risk was negatively associated with temperature, wind speed, and carbon monoxide, while nitrous dioxide and the human modification index presented a positive effect. Pollution gases presented a marked variability during the study period, showing a decrease of CO. These findings suggest that controlling and monitoring urban emissions of pollutant gases is a key factor for the reduction of risk derived from COVID-19.

Abstract
BACKGROUND A characteristic feature of SARS-CoV-2 is its ability to transmit from pre- or asymptomatic patients, complicating the tracing of infection pathways and causing outbreaks. Despite several reports that whole genome sequencing (WGS) and haplotype networks are useful for epidemiologic analysis, little is known about their use in nosocomial infections. AIM We aimed to demonstrate the advantages of genetic epidemiology in identifying the link in nosocomial infection by comparing single nucleotide variations (SNVs) of isolates from patients associated with an outbreak in Showa University Hospital. METHODS We used specimens from 32 patients in whom COVID-19 had been diagnosed using clinical reverse transcription-polymerase chain reaction tests. RNA of SARS-CoV-2 from specimens was reverse-transcribed and analysed using WGS. SNVs were extracted and used for lineage determination, phylogenetic tree analysis, and median-joining analysis. FINDINGS The lineage of SARS-CoV-2 that was associated with outbreak in Showa University Hospital was B.1.1.214, which was consistent with that found in the Kanto metropolitan area during the same period. Consistent with canonical epidemiological observations, haplotype network analysis was successful for the classification of patients. Additionally, phylogenetic tree analysis revealed three independent introductions of the virus into the hospital during the outbreak. Further, median-joining analysis indicated that four patients were directly infected by any of the others in the same cluster. CONCLUSION Genetic epidemiology with WGS and haplotype networks is useful for tracing transmission and optimizing prevention strategies in nosocomial outbreaks.

Abstract
Objective: To investigate the clinical pathological and epidemiological characteristics of primary esophageal malignant melanoma (PMME). Methods: The clinical pathology data of 180 PMME patients in the esophageal cancer database of the key laboratory of esophageal cancer research in Henan Province from 1973 to 2016 were collected, of which 136 were male, aged (58.5±9.0) years, 44 were female, aged (56.7±12.2) years. Kaplan-Meier and Log rank test were used for survival analysis, Cox regression scale model was used for risk factor analysis. Results: The incidence of PMME is 0.036% (180/500, 000), mostly were male (about 3∶1 for men: female). The common sites of PMME were the lower part of the esophagus (48.9%, 85/174), followed by the middle section of the esophagus (46.0%, 80/174) and the upper part of the esophagus (5.2%, 9/174). No black particles were seen in the PMME cells of 3 patients under microscope, and strong positive expressions of Melan-A and HMB453 were observed in these 3 patients by immunohistochemical results. Of the 129 patients who had a routine preoperative esophageal biopsy, 69 were undiagnosed with PMME (53.5%). The medium survival time of the whole group was 7.9 months, and the survival rates of 1, 2, 3, 5 years were 25.0%, 7.9%, 6.6% and 1.3%, respectively. The univariate analysis showed that N, M, TNM phase and radiotherapy were related to the overall survival of patients (P<0.05). Multivariate analysis showed that TNM phase and radiotherapy were the independent risk factors for overall survival of patients (P<0.05). Conclusions: PMME is more common in men, the common site of the disease is the lower part of the esophagus. The preoperatively missed diagnosis rate of Chinese PMME is high. TNM phase and radiotherapy are the independent risk factors for overall survival of patients.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection is a major global public health concern. North African countries carry a disproportionate burden of HIV representing one of the highest rates in Africa.
AIM To characterize the epidemiological and spatial trends of HIV infection in this region.
METHODS A systematic review was carried out on all the published data regarding HIV/acquired immunodeficiency syndrome in North African countries over ten years (2008-2017) following the PRISMA guidelines. We performed a comprehensive literature search using Medline PubMed, Embase, regional and international databases, and country-level reports with no language restriction. The quality, quantity, and geographic coverage of the data were assessed at both the national and regional levels. We used random-effects methods, spatial variables, and stratified results by demographic factors. Only original data on the prevalence of HIV infection were included and independently evaluated by professional epidemiologists.
RESULTS A total of 721 records were identified but only 41 that met the criteria were included in the meta-analysis. There was considerable variability in the prevalence estimates of HIV within the countries of the region. The overall prevalence of HIV ranged from 0.9% [95% confidence interval (CI) 0.8-1.27] to 3.8% (95%CI 1.17-6.53). The highest prevalence was associated with vulnerable groups and particularly drug abusers and sexually promiscuous individuals. The dense HIV clustering noted varied from one country to another. At least 13 HIV subtypes and recombinant forms were prevalent in the region. Subtype B was the most common variant, followed by CRF02_AG.
CONCLUSION This comprehensive review indicates that HIV infection in North African countries is an increasing threat. Effective national and regional strategies are needed to improve monitoring and control of HIV transmission, with particular emphasis on geographic variability and HIV clustering.

Abstract
Salmonella is a major foodborne pathogen worldwide, causing serious cases of morbidity and mortality due to the consumption of contaminated foods. Animal-borne foods were considered the main source of transferring Salmonella to humans; however, route surveillance by genomic platforms along the food-chain is limited in China. Here, we proceeded to the application of whole genome sequencing in the epidemiological analysis of Salmonella isolated along the food-chain in Xinjiang, China. A total of 2408 samples were collected from farms, slaughterhouses, and markets, and subjected to the isolation of Salmonella strains. 314 (13.04%) of the samples were positive for Salmonella. Phenotypic antimicrobial resistance was conducted by the broth dilution method using 14 antimicrobial agents belonging to ten classes for all 314 isolates. A selection of representative 103 isolates was subjected to whole-genome sequencing for understanding the Salmonella diversity, including serovars, antimicrobial and virulence genes, plasmid types, multi-locus sequence types, and allelic types. We found that S. Agona was the dominant serovar and O:4(B) was the dominant serogroup. The dominant genotype was ST13 and each serovar has a unique MLST pattern. Plasmids prediction reported Col(MGD2)_1 and Col(Ye4449)_1 as the dominant plasmids, in addition to the detection of IncFII(S)_1 and IncFIB(S)_1 carried by all S. Enteritidis isolates. Importantly, virulence genes prediction showed the presence of cdtB gene encoding typhoid toxins, spv genes, and pef gene cluster encoding fimbriae in the genomes of S. Indiana and S. Enteritidis. Phenotypic antimicrobial resistance identified 92.04% of the sampled isolates as multi-drug resistance (MDR), with high resistance to tetracycline (78.03%; 245/314), amoxicillin/ clavulanic acid (75.80%; 238/314), and ampicillin (70.70%; 222/314). Together, we firstly reported the prevalence of MDR Salmonella isolates harboring critical virulence factors transmission via animal-borne food-chain in Xinjiang, hence route surveillance by whole-genome sequencing platform could facilitate recognition and project early warning for the emerging MDR clones along the food-chain.

Abstract
Objective: To understand the possible transmission route of a family cluster of COVID-19 in Zhengzhou and the potential infectivity of COVID-19 in incubation period, and provide scientific evidence for the timely control of infectious source and curb the spread of the epidemic. Methods: Epidemiological investigation was conducted for a family cluster of COVID-19 (8 cases) with descriptive epidemiological method, and respiratory tract samples of the cases were collected for the nucleic acid detection of virus by RT-PCR. Results: Two primary cases, which occurred on 31 January and 1 February, 2020, respectively, had a common exposure history in Wuhan. The other six family members had onsets on 30 January, 31 January, 1 February (three cases) and 3 February, 2020. Conclusions: In this family cluster of COVID-19, six family members were infected through common family exposure to the 2 primary cases. Five secondary cases had onsets earlier than or on the same day as the primary cases, indicating that COVID-19 is contagious in incubation period, and the home isolation in the early phase of the epidemic might lead to the risk of family cluster of COVID-19.

Abstract
Tuberculosis (TB) is a serious global public health threat, and school-clustered outbreaks are common. Here, we report a TB outbreak in a high school in southern China, which was confirmed and characterized by traditional epidemiological methods and whole-genome sequencing (WGS) of Mycobacterium tuberculosis isolates. All students and faculty (n = 287) were screened by chest X-ray for active TB. TB was diagnosed in 28 patients, according to laboratory confirmation (n = 11) of Mycobacterium tuberculosis, sputum/bronchoalveolar fluid culture, smear, or TB-Xpert. Clinically diagnosed TB cases (n = 17) were further defined by the interferon-γ releasing assay or clinical and radiological findings. Twenty-five of the affected individuals were 12th grade students aged 16 to 19 years; among them, 24 patients were male and 21 had visited the internet café near the school. WGS and phylogenetics analysis confirmed that the outbreak was mainly caused by a super transmission strain of lineage 4.2, which was susceptible to all tested antibiotics. After a treatment regimen of 9 to12 months, all 28 patients were cured. This study highlights the key factors contributing to school-clustered TB outbreaks mainly derived from a single super transmission strain, along with effective interventional measures to prevent a larger scale outbreak.

Abstract
BACKGROUND To carry out a complete clinical, pathological, genetic and microbiological characterization of pediatric patients with molecular confirmed cystic fibrosis (CF) attending the Carlos Andrade Marín Hospital (HCAM) within the study period. METHODS A cross-sectional analysis of the pediatric population with a confirmed diagnosis of CF disease who attended HCAM, one of the largest tertiary-level hospitals in Ecuador, between 2017 and 2018 was performed. All demographic, clinical and genetic variables were obtained from the electronic medical records (EMR) stored by the hospital. RESULTS Forty seven patients with CF were included in the study. Gender distribution was similar between male (48.9%, n = 23) and female patients (51.1%, n = 24). The Tiffeneau-Pinelli index (FEV1/FVC) changed significantly after nine months post-diagnosis (85.55 ± 13.26; p < 0.05). The most common pathogenic genetic variants were F508del, found in 52.78% of the cohort (n = 19); H609R, found in 36.11% (n = 13); g.204099A > C, found in 14.1% (n = 7), followed by G85E and the N1303K with 11.11% (n = 3) each. CONCLUSIONS To our best knowledge, this is the first study exploring the clinical, genetic and bacteriological profile of CF's patients in Ecuador. Within the cohort of patients, an important and unique genetic feature was characterized by the presence of the g.204099A > C and the c.206359C > A homozygous polymorphism as well as the presence of the H609R variant, a mutation only reported among Ecuadorians.

Abstract
The present study was designed to identify nine Arcanobacterium phocae strains isolated from cases of mink dermatitis of a single farm in Finland and characterize the strains for epidemiological relationships. All nine strains and previously described A. phocae used for comparative purposes were identified and further characterized phenotypically, by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), by Fourier Transform Infrared Spectroscopy (FT-IR) and genotypically by detection of phocaelysin encoding gene phl with a previously developed loop-mediated isothermal amplification (LAMP) assay and by sequencing 16S rRNA gene and gene phl, the elongation factor tu encoding gene tuf and the β subunit of bacterial RNA polymerase encoding gene rpoB. Genetic relatedness among isolates was determined using whole-genome single nucleotide polymorphism (wgSNP) analysis. The wgSNP results, partly the MALDI-TOF MS and FT-IR analyses and sequencing of the genes, revealed that the nine A. phocae strains recovered from a single farm showed close sequence similarities among each other and differed from previously investigated A. phocae strains isolated from other farms and animals in Finland and from the A. phocae type strain. This indicated a close epidemiological relationship of the A. phocae strains isolated from a single farm and that the nine A. phocae strains of the present study might have developed from a common ancestor.

Abstract
Objective: To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture. Methods: The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System. Results: From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD(4)(+) T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD(4)(+) T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD(4)(+)T lymphocytes levels< 200/μl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/μl in the last CD(4)(+)T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year. Conclusion: Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.

Abstract
Purpose There are limited population-based data regarding herpes zoster in children. Thus we conducted a multi-institutional epidemiological analysis of herpes zoster in children and comparative analysis according to their immune status. Materials and Methods The study included 126 children under the age of 18 years who were hospitalized for herpes zoster at 8 hospitals in South Korea, between July 2009 and June 2015. The subjects were divided into 2 groups according to their immune status, and medical records were reviewed. Results There were 61 cases (48.4%) in the immunocompetent group and 65 cases (51.6%) in the immunocompromised group. Median age was older in immunocompromised group (11.4 vs. 8.6) (p<0.001). The mean duration of hospitalization was longer in immunocompromised group (11.0 vs. 6.6) (p<0.001). Patients were treated with oral or intravenous antiviral agents. A total of 12 in immunocompetent group were cured only by oral acyclovir. No treatment failure was found in both groups. Six immunocompromised patients had postherpetic neuralgia and 1 case was in immunocompetent group. In immunocompetent children, herpes zoster was likely caused by early varicella infection. There was no increase in progression of severity in both groups due to appropriate treatment. Conclusion Early initiation of therapy is necessary for those in immunocompromised conditions. And inactivated herpes zoster vaccination may be considered in immunocompromised adolescents in the future.

Abstract
PURPOSE The aims of the present study are to present the epidemiology and management of patients hospitalized with odontogenic infections in a major Greek hospital from 2015 to 2016 and to find out whether the basic principles of management of odontogenic infections were followed before referral to the emergency department of the Oral and Maxillofacial Surgery Clinic (OMFSED). METHODS A retrospective study of the patients hospitalized with odontogenic infections was performed, including management both prior and after referral to the OMFSED. RESULTS During the two-year period from 2015 to 2016, 102 patients, 54 men (52.9%) and 48 women (47.1%) were hospitalized with severe odontogenic infections. The most common space involved in severe odontogenic infections was the submandibular (52.9%), and in 31.4% of the patients multiple spaces were involved. The lower third molars were the most common cause (36.5%). In 83 patients (81.4%) the tooth causing the infection had not received any treatment whatsoever and in all cases (100%) no decision for early incision and drainage prior to the referral to the OMFSED was made. CONCLUSION The data presented reveal that the basic principles of management of odontogenic infections are not followed before referral of the patients to the OMFSED.

Abstract
Seneca Valley virus (SVV), a newly determined etiological agent of vesicular disease in swine, causes porcine idiopathic disease and occasional acute death in piglets. Recently, an increased number of SVV infection cases have been reported in the United States (US) and China, resulting in significant economic losses to the swine industry. The first identification of SVV in China was reported in Guangdong Province, a major swine producing province. The cases of SVV were continuously reported in Guangdong in 2015 and 2016. However, the spread of SVV in Guangdong in 2017 remains unknown. In this study, we determined two new SVV strains, CH-GD-2017-1 and CH-GD-2017-2, from Guangdong. The genetic analysis suggested that the two Guangdong strains showed different characteristics to previous Guangdong strains. They showed lower nucleotide similarity with strains isolated in 2015 and 2016, and were more similar to the US strains. Phylogenetic analyses indicated that the new strains were clustered in a different clade with previous Guangdong strains. We found 28 mutated amino acids in the new strains, compared with the first Guangdong strain, SVV CH-01-2015. In the geographic analysis, we found that the US and China reported more SVV cases than other countries, and most of the SVV cases were reported in east and central China-of which, Guangdong Province is one of the major epidemic regions. In conclusion, our findings indicate that SVV continued to spread in Guangdong Province in 2017, and two different clades of SVVs have emerged in this region.

Abstract
Background Haemophilus influenzae (H. influenzae) is one of the most important pathogenic bacteria causing respiratory tract infection diseases in children. There are two main types of H. influenzae, encapsulated H. influenzae and nontypeable H. influenzae (NTHi). Serotype b of H. influenzae (Hib) used to be the main epidemic type of H. influenzae, causing the invasive infection. However, the epidemiology of invasive H. influenzae disease has changed substantially, and most invasive diseases are now caused by NTHi and other serotypes of H. influenzae. The aim of this study was to determine the main epidemic strains of H. influenzae in Zhejiang Province in China, and establish a one-step multiplex PCR assay to distinguish H. influenzae from other bacteria associated with respiratory tract infections, and distinguish encapsulated H. influenzae from NTHi. Method In this study, bacterial culture and serum agglutination testing were used to determine the most prevalent serotype of H. influenzae, and the results have served as a gold standard for clinical diagnosis. We also designed a one-step multiplex PCR assay using several kinds of standard strains of respiratory tract infection bacteria, to examine the stability, specificity, and detection limit of the PCR assays. We then used 1514 nasopharyngeal secretion (NPS) samples collected from children with respiratory tract infections to verify the specificity and sensitivity of the PCR assay. Results The bacterial culture and serum agglutination test results showed that the positive rates of H. influenzae and encapsulated H. influenzae were 18.49 and 1.18%, respectively. The PCR results showed that the detection limit of the multiplex PCR assay was 1.89 × 103 copies /μL, the ompP6 positive rate was 19.35%, and the bexA positive rate was 1.32%. The sensitivity and specificity of the multiplex PCR were 100 and 99.86%, respectively. Conclusions According to our study, the most prevalent H. influenzae subtype in Zhejiang Province was NTHi, account for 93.57%; the one-step multiplex PCR assay we established can be used as the differential detection of clinical H. influenzae strains, replacing routine bacterial culture and serum agglutination testing.

Abstract
AIM To analyze the epidemiological characteristics of upper gastrointestinal diseases in people of China's ethnic minorities in Menghai County.
METHODS The clinical data for 21020 patients who underwent gastroscopy at Menghai People's Hospital from September 2001 to September 2016 were analyzed retrospectively, including age, ethnic group, and the detection of upper gastrointestinal diseases.
RESULTS In 21020 patients, the ratio of men to women was 1:1.1 and their age ranged from 9 to 85 years old, including 7858 Han people, 6831 Dai people, 3227 Hani people, 1904 Pulang people, 1016 Lahu people, 73 Yi people, and 111 people of other ethnic minorities. By yearly statistics, the number of cases who underwent gastroscopy began to rise year by year since 2011. By monthly statistics, the number of cases who underwent gastroscopy was significantly higher in May to September than in the other months each year. Non-atrophic gastritis was most common, followed by erosive gastritis, bile reflux, duodenal ulcer, gastric ulcer, duodenitis, gastric retention, reflux esophagitis, gastric cancer, esophageal varices, gastric polyps, gastric cardia tear, and duodenal polyps. There was no difference in the monthly detection rate of season-related upper gastrointestinal diseases. There was no difference in the incidence of upper gastrointestinal diseases among all ethnic groups, but it was higher than that in Shanghai.
CONCLUSION The incidence of non-atrophic gastritis is highest among upper gastrointestinal diseases in people of ethnic minorities in Menghai County. The incidence of upper gastrointestinal diseases is not significantly different among all ethnic groups, but higher than that in Shanghai.
