Serum bone alkaline phosphatase (BAP) , osteocalcin (OC) , C-telopeptides of type-1 collagen (CTx) , osteoprotegerin (OPG) levels, and bone mineral density (BMD) were evaluated in 62 hyperthyroid patients and 60 healthy subjects matched for sex and age. In hyperthyroid patients, the biochemical evaluations and bone density were performed before and after 6 months of methimazole ( MMI) treatment. Results showed that the BMD in lumbar spine L2 - L4, neck of femur, Ward's triangle and greater trochanter of patients before treatment were all significantly lower than those in healthy controls, and improved markedly after MMI treatment. The serum bone turnover parameters BAP, OC and CTx in patients before treatment were all significantly higher than those in control group, and were decreased markedly after treatment. The serum OPG level in patients with hyperthyroidism was significantly higher than that in healthy controls, and decreased markedly after treatment. The serum OPG levels were significantly correlated with bone turnover parameters ( BAP, OC, CTx) and BMD, which indicates that serum OPG level can reflect the abnormality of bone metabolism in patients with hyperthyroidism.

Objective To investigate the sleep quality of maintenance hemodialysis (MHD) patients and analyze its associated factors. Methods The convenience sample method was used to choose 424 MHD patients from 7 hospitals.A set of questionnaires were used in this investigation,including demographic data form,Pittsburgh sleep quality index (PSQI),restless legs syndrome (RLS),social support rate scale (SSRS),subjective global assessment (SGA),family APGAR index (APGAR) and family burden scale of disease (FBS). Results PSQI score of 395 MHD patients (93.2%) was ≥5.APGAR and social support total points were negatively correlated with sleep quality (r=-0.133,P=0.006; r=-0.105,P=0.031).Family burden total point was positively correlated with sleep quality (r=0.215,P=0.000).Nutrition (F=46.123,P=0.000),restless legs syndrome (F=9.392,P=0.000) and sleep apnea syndrome (F=5.645,P=0.001) were closely associated with sleep index scores. Conclusions Incidence of poor sleep quality in MHD patients of our study is quite high.Sleep quality of MHD patients is correlated with lots of factors,such as family concern,social support.

To investigate the clinical features, early recognition and prognosis of influenza-associated intracranial aspergillosis. The clinical data of a child with influenza-related intracranial aspergillosis admitted to the Department of Pediatrics of the Third Xiangya Hospital of Central South University in 2022 were retrospectively analyzed. By searching CNKI, Wanfang Database, Web of Science, PubMed and other Chinese and English databases as of November 2023, literature was screened according to inclusion and exclusion criteria, and the clinical characteristics, diagnosis, treatment and prognosis of all influenza-related intracranial aspergillus disease were summarized. A total of 5 reports of 5 cases of influenza-associated aspergillosis were obtained, including 1 child patient and 1 child influenza-associated intracranial aspergillosis in this study, and a total of 6 influenza-associated aspergillosis patients. The clinical manifestations of the 6 patients were disturbance of consciousness, hemiplegia, pupil changes, behavioral abnormalities, epilepsy, etc. Most of the cases were diagnosed through pathology or autopsy to find pathogens. In this case, the pathogens were confirmed through metagenomic next-generation sequencing (mNGS). Antifungal drugs were the first choice for treatment. 66.7% of the surviving patients received surgical treatment, and the mortality rate of 6 patients reached 50.0%. Influenza-associated intracranial aspergillosis is rare, can occur in both children and adults, and has a poor prognosis. In the early stage of influenza, if there are neurological symptoms, screening for fungal infection should be conducted. Acer second generation sequencing can improve the diagnosis rate of intracranial aspergillosis.

Objective To analyze the pulse-field gel electrophoresis (PFGE) patterns and antibiotic resistance of Salmonella enteritidisstrains isolated in Longyan city in order to provide reference for effective control, clinical diagnosis and treatment of outbreaks of food-borne diseases.Methods Seventy-seven Salmonella enteritidis strains isolated from food poisoning cases, livestock and poultry meat samples collected for food safety risk monitoring and sporadic cases in 2014 and 2016 were analyzed by PFGE.Antibiotic susceptibility testing was carried out to determine the minimum inhibitory concentrations (MIC) of 16 common antibiotics to 57 strains.Results Seventeen PFGE types were identified among the 77 Salmonella strains including three predominant types (P4, P6 and P8) and were grouped into three major pulsotypes (Cluster1-3) at 90% similarity level.The predominant types causing outbreaks of Salmonella enteritidis infection were P8, P6, P4 and P14, which were responsible for five cases of food poisoning.These isolated strains were highly resistant to nalidixic acid (93%), followed by resistance towards ampicillin (74%) and streptomycin (54%).Forty-one strains were resistant to three or more antibiotics (71.93%).Conclusion The PFGE types of Salmonella enteritidis strains isolated in Longyan city exhibit polymorphism and are clustered into three major pulsotypes.PFGE molecular typing can provide early-warning of sporadic outbreaks and help to identify the sources of infections in Salmonella enteritidis-related food poisoning.Attentions should be paid to multidrug resistant Salmonella enteritidis.Surveillance for multidrug resistant strains and usage of antibiotics should be strengthened.

This study aimed to analyse the genetically characterize isolates of Echovirus 11 from Longyan City,Fujian Province,and to reveal their genetic relationships with other isolates from China and abroad. Cerebrospinal fluid specimens from patients diagnosed with viral encephalitis or central nervous system (CNS) infections were collected from Longyan First Hospital between January and December 2011. Seven Echo11 strains were isolated and identified using the RIMV serum panel. The entire VP1 coding regions of four strains were sequenced and typed as Echo11 by an online blast program and,subsequently, phylogenet- ic analyses of the VP1 sequences of these stains and others published on GenBank were conducted. There were 600 nucleotides (nt) in each complete VP1 coding region that encoded 200 amino acids (aa). Among those four Echo11 strains, the sequence identities of nt and aa were 100% and 99%-100% respectively. And phylogenetic analyses indicate belong to subtype DS, the homology compared with DS strain (GU393713) were 93% (nt) and 99% (aa). The sequence identities for the nt and aa were 75%-76% and 90%, respectively, between the current isolates from Longyan and the Gregory prototype strain found in 1953. The sequence identity of nt and aa between the Longyan virus strains and the domestic Shandong strains isolated in 2010 were lower, at 74% and 88%-89%, respectively. However,the highest level of ho- mology was found when the Longyan strains were compared with the Netherlands strain (GU393773) found in 2007 (nt and aa identity: 94%-95% and 98%-99%, respectively). The relatively low levels of similarity between domestic isolates suggest that different transmission routes exist for Echo11 in mainland China.

Objective To analyze the genetic characteristics of echovirus type 25( Echo25) strains isolated from patients with viral encephalitis in Longyan city. Methods Cerebrospinal fluid(CSF) specimens were collected from hospitalized patients with viral encephalitis or central nervous system infection in Longyan,2012. Enteroviruses(EV)were isolated from the specimens and then identified. Four strains of Echo25 were screened out by using serum neutralization test. Coding sequence of the VP1 region of the 4 Echo25 strains were amplified by RT-PCR and then sequenced. A phylogenetic tree was constructed to ana-lyze the nucleotide sequence homology between those sequences and the sequences of reference Echo25 strains available in the GenBank database. Results The VP1 nucleotide sequences of Echo25 strains isola-ted in Longyan were 498 bp in length,encoding 166 amino acid residues. The homology analysis showed that the VP1 nucleotide sequences of 3 strains were identical,sharing 97% homology in nucleotide with the rest strain. The Echo25 strains isolated in Longyan were highly similar to KJ957190( Beijing,2010)and HM031189(Henan,2008)strains. Phylogenetic analysis revealed that the Echo25 strains isolated in Longyan belonged to genotype B1. Conclusion Echo25 was one of the pathogens causing viral encephalitis in Longyan in 2012 and different transmission chains of Echo25 had emerged. This study indicates that it is necessary to strengthen the surveillance for EV and understand the genetic variation of the Echo25 for provi-ding better supportive evidences for the prevention and control of related diseases.
