Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Bariatric surgery is the most effective treatment for patients with severe obesity, which can significantly improve the metabolic disorders, especially type 2 diabetes mellitus. Bariatric and metabolic surgery is the latest and fastest-growing branch of surgery, with the types of procedure and other novel treatment modalities are still evolving and in progress. The authors summarize the recent advancement related to novel bariatric and metabolic surgery in the treat-ment of morbid obesity and type 2 diabetes mellitus in recent years through literature search, which can be divided into the following three parts: (1) novel surgical procedures and new guideline of indication. Sleeve gastrectomy and Roux-en-Y gastric bypass are the most performed bariatric surgery. Duodenal switch or the variant of one anastomosis duodenal ileostomy are also accredited procedures but been less performed. One anastomosis gastric bypass is the most recently accredited bariatric surgical procedures with better safety profile and weight loss efficacy than most of the procedures. For other novel procedures, bipartition procedure may be the next accredited proce-dure. A new worldwide guideline is recently launched and the indication for bariatric surgery is lowered BMI 27.5 kg/m 2 for Asian. (2) The effect and mechanism of bariatric surgery. Bariatric surgery can significantly reduce the incidence of cardiovascular disease and mortality in obese patients. The main beneficiary group is patients with diabetes mellitus. Along with the recent basic research and the success of new gut hormone related drugs, the mechanism of bariatric surgery can be mostly attributed to gut hormonal effect, however, gastric volume still play an important role. (3) Novel obesity treatment modalities. Endoscopic obesity treatment has a major progress in the success of endoscopic gastroplasty by endoscopic suturing designs. More noteworthy is the development of new intestinal hormone drug therapy, which can achieve a weight loss of 14% in one year by injec-ting once a week glucagon-like peptide-1 preparation, and then combining two or three intestinal hormone drugs can achieve a weight loss of 24% in one year, which is close to the effectiveness of bariatric surgery. Pharmacologic treatment of obesity is very promising and expected. With the increasing severity of obesity and diabetes mellitus in the world, in addition to the explosive develo-pment of bariatric and metabolic surgery in recent years, many new surgical methods and new treatments, especially new and effective intestinal hormone related therapeutic drugs, have been developed. The success of bariatric and metabolic surgery depends on a multidisciplinary team with rich clinical experience: precise preoperative planning and comprehensive postoperative manage-ment, as well as patient understanding and cooperation, in order to achieve the best results.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Objective:To investigate the effect of insular involvement on the outcomes of patients with acute anterior circulation ischemic stroke.Methods:Patients with acute anterior circulation ischemic stroke admitted to the Department of Neurology, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to December 2020 were retrospectively included. Demographic data, vascular risk factors, clinical and laboratory data, as well as treatment and outcomes were collected. Firstly, the correlation between the insular involvement and the outcomes was investigated, and then the bootstrap method was used to clarify the mediating role of infarct volume between the insular involvement and the poor outcomes.Results:A total of 450 patients with acute anterior circulation ischemic stroke were enrolled, among whom 79 cases (17.6%) had insular involvement and 41 (9.1%) had left insular involvement. There were 111 (24.7%) with poor outcomes, including 5 (1.1%) died. Compared to the non-insular involvement group, the insular involvement group had a higher proportion of patients with atrial fibrillation, shorter onset to door time, higher neutrophil-to-lymphocyte ratio (NLR), higher National Institutes of Health Stroke Scale (NIHSS) score at admission, larger infarct volume, and higher proportion of patients with poor outcomes (all P<0.05). In addition, patients with left insular involvement were younger than those with right insular involvement, had a higher baseline NIHSS score, a lower proportion of patients with minor stroke (NIHSS score ≤8), and had a longer onset to door time (all P<0.05). Compared to the good outcome group, the poor outcome group was older, with a higher proportion of female patients, higher systolic blood pressure, blood glucose, NLR, and NIHSS scores at admission, larger infarct volume, and a higher proportion of patients with insular involvement (all P<0.05). Mediation analysis suggested that the mediating effect of infarct volume between the insular involvement and the poor outcomes was significant (95% confidence interval 0.033-0.230; P=0.008). Conclusions:insular involvement in patients with acute anterior circulation ischemic stroke is associated with the poor outcomes, and this association may be mediated by infarct volume. Patients with left insular involvement may have more severe symptoms than those with right insular involvement, but there is no significant difference in the outcomes.

ObjectiveTo determine the genomic characteristics of a subgenus B human adenovirus strain isolated in Shanghai in 2021. MethodsAn adenovirus type 55 strain was isolated and identified from a patient with acute hemorrhagic conjunctivitis (AHC). Complete genome of the strain was obtained using the next-generation sequencing (NGS). Phylogenetic trees were reconstructed based on the sequences of Hexon, Fiber, Penton and complete genome to genomically characterize this strain. ResultsPhylogenetic analysis based on the complete genome classified this strain (MH2021001) into subgenus B, subspecies B2 of HAdV-55. Hexon gene of MH2021001 had close phylogenetic relationship with HAdV-11, while Fiber and Penton genes had close relationship with HAdV-14. The MH2021001 showed high nucleotide identity with currently prevalent HAdV⁃55 strains (>99.90%). The complete genome had 99.96% nucleotide identity to the 73-GD_CHN_2016 strain isolated in Guangdong. In addition, the amino acid sequence of MH2021001 had several substitutions in regions coding for E1B, L4, E3 and L5. ConclusionThis strain has been classified to HAdV-B55. No recombination event is identified in the complete genome. Due to multiple amino acid substitutions, the biological characteristics of the strain need to be further identified.
