The technology of three-dimensional(3D)printing emerged in the late 1970s and has since undergone considerable development to find numerous applications in mechanical engineering,industrial design,and biomedicine.In biomedical science,several studies have initially found that 3D printing technology can play an important role in the treatment of diseases in hepatopancreatobiliary surgery.For example,3D printing technology has been applied to create detailed anatomical models of disease organs for preoperative personalized surgical strategies,surgical simulation,intraoperative navigation,medical training,and patient education.Moreover,cancer models have been created using 3D printing technology for the research and selection of chemotherapy drugs.With the aim to clarify the development and application of 3D printing technology in hepatopancreatobiliary surgery,we introduce seven common types of 3D printing technology and review the status of research and application of 3D printing technology in the field of hepatopancreatobiliary surgery.

Objective:To analyze the epidemiological characteristics of norovirus (NoV) acute gastroenteritis (AGE) outbreaks caused by GII.17[P17] variant in China, 2022.Methods:Information and specimens of AGE outbreaks between January and December 2022 were collected. NoV RNA was detected in all specimens by real-time RT-PCR. The viral genome of the positive specimens were amplified, sequenced and analyzed.Results:Between January and December 2022, 360 AGE outbreaks were reported cumulatively, of which 266 outbreaks successfully obtained genotype results. GII.17 [P17] was one of the main genotypes and detected in 34 outbreaks (12.78%, 34/266), with the highest number of outbreaks detected in spring (6 outbreaks in March and 7 outbreaks in May), mainly in childcare facilities and primary schools (61.76%, 21/34). According to the result of NoV genotype analysis in different age groups, 14 strains of GII.17 [P17] in this study belonged to Cluster III b and SC III branch of Cluster III (Kawasaki308) in the capsid region and polymerase region, respectively, and both belonged to the same cluster as the variant strain (GZ41621 strain) that caused the NoV AGE outbreaks in China during the 2014/15 season. Compared to reference strains of Cluster I, Cluster II and Cluster III a, Cluster III b was provided with 22 amino acid mutations in VP1. The main amino acid changes in the subgroup of Cluster III b including the virus strains isolated in this study were at T294I and Q299R of antigen epitope A, an insertion mutation occurred at antigen epitope D, H353Q at the site I of the human histo-blood group antigen receptor binding site. The selection pressure analysis detected a large number of negative selection sites, indicating that negative selection plays an important role in the evolution of VP1 genes.Conclusions:GII.17 [P17] was one of the primary genotypes responsible for NoV diarrhea outbreaks in China in 2022. Phylogenetic analysis had revealed that it still belonged to the same cluster as the novel GII.17 [P17] variant (strain GZ41621) that caused NoV epidemics in China during the 2014/15 season, exhibiting minor amino acid variations at the potential epitope.

Objective:A recombinant adenoviral vector vaccine based on non-replicating human adenovirus type 5 (Ad5), encoding the conserved domain of respiratory syncytial virus G protein (RSV-G) was constructed. The immunogenicity and protective efficacy of this vaccine were subsequently evaluated in mice.Methods:The recombinant Ad5 vector plasmid (Ad5-Gbcc-Gacc) was constructed by inserted conserved domains of RSV A and RSV B. The recombinant adenovirus Ad5-Gbcc-Gacc was rescued in HEK293A cells. The genome of virus Ad5-Gbcc-Gacc was identified by multi-enzyme digestion, and the expression of Ad5-Gbcc-Gacc was verified by Western blot. Recombinant adenovirus was used to immunize BALB/c mice via intramuscular injection with signal dose, and then challenged with RSV Long strain at week 6. The levels of G specific IgG and antibody subtypes in serum were detected by enzyme-linked immunosorbent assay, the level of neutralizing antibodies was determined by micro-neutralization assay. After challenge, the mice′s weight was recorded daily, the copies of RSV virus in the lung and nasal tissues were detected. Pathological changes in lung tissue were also examined.Results:Western blot and multi-enzyme digestion identification confirmed the successful rescue of the recombinant adenovirus. Ad5-Gbcc-Gacc elicit high titers of specific IgG, robust neutralizing antibodies, and a balanced Th1/Th2 immune response in mice. In comparison to unimmunized controls, mice immunized with Ad5-Gbcc-Gacc reduced the viral copies in both lung and nasal tissue, and exhibited only minimal pathological damage of lung tissue following RSV challenge. In conclusion, Ad5-Gbcc-Gacc induced robust immunogenicity and offers protective effects against RSV infection in murine models.Conclusions:Ad5-Gbcc-Gacc induce robust immunogenicity and can protect mice from RSV challenge, which lays a foundation for further development of RSV vaccine based on G protein.

Objective To analyze the current research application status and hotspots of nanoparticles in the treatment of non-small cell lung cancer (NSCLC) and predict the future development trend. Methods The Web of Science database was searched for literatures on nanoparticles use in the treatment of NSCLC from inception to November 2022. CiteSpace, VOSviewer and literature measurement analysis online platform (https://bibliometric.com/) were used for the visual analysis of the number of documents, source journals, authors, organizations, countries and keywords. Results A total of 742 English literatures were included. The results showed that the number of published literatures increased year by year from 2011 and reached the peak in 2020. Researches on nanoparticles and NSCLC treatment were mainly concentrated in China, the United States, India and Japan. China is a major research country in this field, but it lacked cooperation with other countries and related institutions. Among numerous research institutions, the Chinese Academy of Sciences was the authoritative and backbone force in this research field, with the number of published literatures ranking first and the research achievements outstanding. The keyword analysis found that "poly lactic-co-glycolic acid nanoparticles (PLGA NPs)" and "photothermal therapy" had become the latest breakout words since 2018. Moreover, the occurrence frequency of related keywords such as "drug delivery" increased significantly, indicating that the application of PLGA NPs in photothermal therapy might be the current research hotspot and future development trend of NSCLC treatment. Conclusion Currently, the domestic research on the treatment of nanoparticles and NSCLC is in a leading position in the world. The organic combination of nanoparticles with different materials and other NSCLC therapies is expected to improve the prognosis of NSCLC patients. In the future, attempts to develop nanoparticles with different sources and structures and combined with photothermal therapy for the treatment of NSCLC may become a research hotspot of nanoparticles in the treatment of NSCLC.

Shear thinning is an ideal feature of bioink because it can reduce the chance of blocking. For extrusion based biological printing, bioink will experience shear force when passing through the biological printer. The shear rate will increase with the increase of extrusion rate, and the apparent viscosity of shear-thinning bioink will decrease, which makes it easier to block, thus achieving the structural fidelity of 3D printing tissue. The manufacturing of complex functional structures in tissue trachea requires the precise placement and coagulation of bioink layer by layer, and the shear-thinning bioink may well meet this requirement. This review focuses on the importance of mechanical properties, classification and preparation methods of shear-thinning bioink, and lists its current application status in 3D printing tissue trachea to discuss the more possibilities and prospects of this biological material in tissue trachea.

Objective To investigate the impact of the timing of continuous renal replacement therapy (CRRT) on the efficacy and prognosis of patients with septic shock undergoing bundle therapy. Methods A total of 84 patients with septic shock who underwent bundle therapy were enrolled, receiving bundle therapy. Based on the timing of CRRT, the patients were divided into early CRRT group and late CRRT group, with 42 patients in each group. Clinical data (heart rate, time to normalization of body temperature, ICU length of stay) and infection status[C-reactive protein (CRP), procalcitonin (PCT)]and immune function (CD4⁺, CD8⁺, CD14⁺), as well as the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores before and after treatment were compared between the two groups. The 28-day survival of patients in both groups was also followed up. Results The heart rate in the early CRRT group was lower than that in the late CRRT group, and the time to normalization of body temperature and ICU length of stay were shorter in the early CRRT group compared with the late CRRT group (P < 0.05). After treatment, the levels of CRP and PCT in both groups were lower than those before treatment, and their levels in the early CRRT group were lower than those in the late CRRT group (P < 0.05). After treatment, the levels of CD8⁺ in both groups were lower than those before treatment, and the early CRRT group had lower level than that in the late CRRT group (P < 0.05); after treatment, the levels of CD4⁺ and CD14⁺ in both groups were higher than those before treatment, and their levels in the early CRRT group were higher than those in the late CRRT group (P < 0.05). After treatment, the APACHE Ⅱ scores of both groups were lower than those before treatment, and the early CRRT group had lower APACHE Ⅱ score than that in the late CRRT group (P < 0.05). The follow-up results showed that the 28-day cumulative survival rate was 83.33%(35/42) in the early CRRT group, which was higher than 64.29%(27/42) in the late CRRT group (P < 0.05). Conclusion For patients with septic shock undergoing bundle therapy, early application of CRRT is superior to late application in clinical efficacy, and contributes to improving the prognosis of patients.
