ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates (P<0.05). Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r0=5, α=0.3, β1=0.08, β2=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (rt≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

Objective To analyze the spatiotemporal clustering characteristics of hand-foot-mouth disease (HFMD) in Songjiang District of Shanghai from 2017 to 2022, and to provide a basis for the prevention and control of HFMD. Methods The number of reported cases of HFMD and population data in Songjiang District from 2017 to 2022 were collected. SaTScan 10.1.2 was used for spatiotemporal scanning analysis, and ArcGis 10.7 was used to visually describe the spatial distribution of HFMD. Results From 2017 to 2022, a total of 12318 cases of HFMD were reported, with an average annual reporting rate of 106.72/100 000. The incidence rate of HFMD from 2017 to 2019 was 174.19/100 000, higher than the incidence rate of HFMD from 2020 to 2022 (43.29/100 000) (P<0.01). From 2017 to 2022, there were cases reported in each month throughout the year, with the peak incidence occurring from May to October each year. The incidence rate of HFMD in each area had obvious spatial clustering. The results of spatiotemporal scanning analysis showed that the high incidence areas of HFMD were mainly distributed in Jiuting Town, Jiuliting Street, Guangfulin Street, Sijing Town, and Dongjing Town (LLR=1199.68, P<0.01). Conclusion The HFMD in Songjiang District of Shanghai shows obvious spatiotemporal clustering distribution. The clustering area is mainly distributed in the northeast of the district. Attention should be paid to high-risk areas and key populations, and targeted preventive measures should be developed.

Objective:To explore the genotype-phenotype relationship of Wilson's disease (WD) and further study the mutation spectrum in the ATP7B gene.Methods:The clinical data and genetic test results of 115 cases with WD diagnosed in the First Affiliated Hospital of Zhengzhou University from 2015 to 2022 were retrospectively analyzed. The rank sum test was used for quantitative data comparison, and χ2 test was used for count data comparison. Multivariate logistic regression was used to analyze the relationship between patients' genotype and phenotype. Results:The onset of liver manifestations (hepatic type) accounted for 60.9%, neurological symptoms (cerebral type) for 13.0%, and mixed hepato-cerebral symptoms for 26.1%. Presymptomatic individuals (hepatic types) accounted for 62.9%. Next-generation sequencing- diagnosed WD cases accounted for 87.8%. Combined multiplex ligation-dependent probe amplification assay-diagnosed WD cases accounted for 89.6%. A single case with a detected pathogenic locus accounted for 10.4%. The diagnostic rate of WD by genetic testing combined with clinical data was 100%. A total of 76 ATP7B mutations were detected, and the top three mutation frequencies were c.2333G>T (p.Arg778Leu) (30.7%), c.2975C>T (p.Pro992Leu) (7.3%), and c.2621C>T (p.Ala874Val) (6.4%). The mutations were mainly distributed in exons 8, 11-13, and 15-18, accounting for more than 90% of the total mutations. Eight new mutations were found, including c.3724G>A (p.Glu1242Lys), c.3703G>C (p.Gly1235Arg), c.3593T>C (p.Val1198Ala), c.2494A>C (p.Lys832Gln), c.1517T>A (p.Ile506Lys), c.484G>T (p.Glu162Ter), c.1870-49A>G, and the missing of exons 10-21. Liver histopathology showed cellular edema, degeneration, inflammation, and necrosis, as well as a 42.8% copper staining positive rate. Genotype-phenotype analysis showed that the p.Arg778Leu mutation had higher alanine aminotransferase (ALT) levels than those carrying other mutations ( P=0.024), while the homozygous mutation of p.Arg778Leu was associated with cerebral-type patients ( P=0.027). Conclusion:Genetic testing plays an important role in the diagnosis of WD. p.Arg778Leu is the first high-frequency mutation in the Chinese population, and patients carrying it have higher ALT levels. The p.Arg778Leu homozygous mutation is prone to causing cerebral-type WD. This study expands the ATP7B gene mutation spectrum.

Objective:To analyze and clarify the clinical and pathogenic gene variation and genetic etiology of polycystic liver disease.Methods:The proband clinical data and family history were collected. Whole-exome sequencing technology was used to detect the proband gene variations. Fluorescence quantitative PCR validation was performed on the proband and his family to screen out pathogenic gene variation.Results:A multiple liver cyst was found in an 18-year-old male proband during a physical examination. There were no abnormalities in his liver function, and both his father and grandfather had multiple liver cysts without any obvious discomfort or other special manifestations. Whole exome sequencing suggested a heterozygous deletion in exon 1 (Exon 1) of the SEC63 gene in the proband. Real-time fluorescence quantitative PCR confirmed that the heterozygous deletion variation of the SEC63 gene Exon 1 of the proband came from his father, and the same heterozygous deletion was detected in his grandfather. The gene variant had a pathogenic variation that had been rarely reported before and was in accordance with the the American college of Medical Genetics and Genomics (ACMG) guidelines.Conclusions:The genetic etiology of this autosomal dominant polycystic liver disease has been clarified, and the heterozygous deletion of Exon1 of the SEC63 gene is a newly discovered gene variation that broadens the variation spectrum of the SEC63 gene.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

BACKGROUND:Previous studies have successfully constructed erythropoietin-overexpressed umbilical cord mesenchymal stem cells.It was found that the apoptosis of ischemic and hypoxic human neuroblastoma cell line(SH-SY5Y)was significantly reduced by erythropoietin-overexpressed umbilical cord mesenchymal stem cells. OBJECTIVE:To explore the possible neuroprotective mechanisms of erythropoietin-overexpressed umbilical cord mesenchymal stem cells against ischemic-hypoxic SH-SY5Y and their associated epigenetic mechanisms. METHODS:Oxygen-glucose deprivation was applied to ischemia-hypoxia-induced SH-SY5Y cell injury,and multifactorial assays were applied to detect the expression levels of inflammatory factors in the cells before and after hypoxia and co-culture,respectively,with mesenchymal stem cells,as well as lentiviral-transfected null-loaded plasmids of the negative control mesenchymal stem cells and erythropoietin-overexpressed umbilical cord mesenchymal stem cells.The expression levels of supernatant inflammatory factors were detected by multifactor assay after co-culture.Proteomics was used to detect the differentially expressed proteins of negative control mesenchymal stem cells and erythropoietin-overexpressed umbilical cord mesenchymal stem cells.Cleavage under targets and tagmentation sequencing was applied to detect genomic H3K4me2 modification,and joint analysis was conducted with RNA-sequencing.Lentiviral vector infection was applied to construct the stable knockdown of REST in SH-SY5Y cells.qRT-PCR and western blot assay were performed to detect the expression level of REST.The apoptosis was detected by flow cytometry after co-culture of oxygen-glucose deprivation treatment with erythropoietin-overexpressed umbilical cord mesenchymal stem cells.The expression difference of H3K36me3 group proteins was detected by western blot assay,and transcriptome sequencing was performed to analyze the differentially expressed genes. RESULTS AND CONCLUSION:(1)Compared with the control group,monocyte chemotactic protein 1,interleukin-6,interleukin-18,and interleukin-1 beta,interferon α2,and interleukin-23 levels significantly increased in the cerebrospinal fluid supernatant of patients with ischemic-hypoxic encephalopathy(P<0.01).(2)After co-culturing SH-SY5Y cells with erythropoietin-overexpressed umbilical cord mesenchymal stem cells under ischemia and hypoxia,the expression levels of monocyte chemotactic protein 1 and interleukin-6 were significantly reduced.(3)Analysis of protein network interactions revealed significant downregulation of monocyte chemotactic protein 1,interleukin-6 related regulatory proteins CXCL1 and BGN.(4)Transcriptome sequencing analysis found that pro-inflammatory genes were down-regulated,and functional enrichment of histone modifications,and the expression of transcription factors REST and TET3 significantly up-regulated in the erythropoietin-overexpressed umbilical cord mesenchymal stem cell group compared with the negative control mesenchymal stem cell group.(5)Combined analysis of transcriptome sequencing and cleavage under targets and tagmentation revealed changes in epigenetic levels as well as significant activation of the promoter regions of transcription factors REST and TET3.(6)Stable knockdown REST in SH-SY5Y cells was successfully constructed;the transcript levels of REST mRNA and protein expression were both decreased.(7)After the REST knockdown SH-SY5Y cells were co-cultured with erythropoietin-overexpressed umbilical cord mesenchymal stem cells,apoptosis was significantly increased and H3K36me3 expression was significantly decreased.Transcriptome sequencing results showed that the expression of inflammation-related genes Aldh1l2 and Cth,as well as apoptosis-suppressor genes Mapk8ip1 and Sod2 was reduced at mRNA transcription level(P<0.01).(8)It is concluded that erythropoietin-overexpressed umbilical cord mesenchymal stem cells activated the expression of REST and TET3 by altering the kurtosis of H3K4me2 and upregulated the modification level of H3K36me3,which in turn regulated the expression of inflammation-related genes Aldh1l2 and Cth,as well as apoptosis-suppressor genes Mapk8ip1 and Sod2,and facilitated neuronal survival.

The key pathogenesis of coronary heart disease (CHD) is spleen deficiency and phlegm stasis, and dysfunctional high-density lipoprotein (dys-HDL) may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein (HDL), it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL; and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways, namely, mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells, thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency, and spleen deficiency makes foundation for the production of dys-HDL; dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen, resolving phlegm, and dispelling stasis, is proposed as an important principle in the treatment of CHD by traditional Chinese medicine, which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL, thus revealing the scientific connotation of this method, and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

OBJECTIVE To provide reference for clinically safe drug use by mining oxaliplatin-related adverse drug events (ADE) of the nervous system. METHODS Oxaliplatin-related neurologic ADE data reported by the FDA adverse event reporting system (FAERS) between January 1st, 2004 and December 31st, 2022 were collected. The reporting odds ratio and proportional reporting ratio were used for data mining. The data were classified statistically by using systematic organ classification, high-level group term (HLGT) and preferred term (PT) in the MedDRA (version 26.0). RESULTS A total of 7 266 cases of oxaliplatin- related ADE, which were classified as various neurological, were retrieved, and 100 PT were identified. Of these, fifty-seven PT were unspecified adverse reaction signals in the manual. Among these reports, males (46.85%) were more than females (42.98%), the age of patients was 45-<75 years (65.22%), the number of reports was highest in Italy (16.32%), and the severe type was hospitalization or prolonged hospitalization (38.16%). The top 5 PT reports in the list of case number were peripheral neuropathy, paresthesia, neurotoxicity, loss of consciousness and dysarthria. The top 5 PT reports in the list of signal intensities were cold- induced paresthesia, neuromuscular rigidity, acute polyneuropathy, neuronal neuropathy, axonal and demyelinating polyneuropathy. A total of 13 HLGT were involved, with neurological diseases (not classified separately) having the highest number of signals (29). CONCLUSIONS When using oxaliplatin in clinical practice, it is not only necessary to monitor the high incidence of acute and chronic peripheral neuropathy, but also to pay attention to the patient’s consciousness state and neurological symptoms. We should pay attention to the rare types of adverse reactions, such as guillain-barre syndrome, Lhermitte sign, posterior reversible encephalopathy syndrome, and hyperammoniacal encephalopathy, so as to ensure the safety of medication.

Standardized reporting is a crucial factor affecting the use of patient guidelines (PGs), particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting, including the research on PG content and presentation formats, and provided comprehensive recommendations for PG reporting from aspects such as overall framework, recommendations, presentation format, and readability. First, the presentation of PG recommendations should include clearly defined clinical questions, recommendations and their rationale, and guidance on how patients should implement the interventions; for specific content in the PG, such as level of evidence, level of recommendation, it is recommended to explain in text the reasons for giving different levels of recommendation, i.e., to present the logic behind giving the level of recommendation to the patient; additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently, the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines (RIGHT-PVG) reporting framework. Finally, to enhance readability and comprehension, it is recommended to refer to the Patient Education Materials Assessment Tool (PEMAT) for translating PG content. To enhance the readability of PGs, it is suggested to present the PG content in a persona-lized and layered manner.
