ObjectiveTo investigate the role of DEAD-box helicase 3 X-linked (DDX3X) in immune-mediated liver injury (ILI), and to clarify its mechanism by regulating endoplasmic reticulum stress (ERS)-dependent apoptotic pathway and its association with the clinical progression of hepatitis B. MethodsMice were given injection of concanavalin A (ConA) via the caudal vein to establish a model of ILI, PBS (control group) and different concentrations of ConA were injected into the tail vein of hepatocyte-specific DDX3X-knockout mice (DDX3XΔHep and DDX3X-flox mice (DDX3Xfl/fl), respectively.. The log-rank survival analysis, measurement of the serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and HE staining of liver tissue were performed to assess liver injury, and qRT-PCR and Western Blot were used to measure the mRNA and protein expression levels of glucose-regulated protein 78 (GRP78), CCAAT/enhancer-binding protein homologous protein (CHOP), and DDX3X in liver tissue. Intraperitoneal injection of 4-phenylbutyric acid (4-PBA, 100 mg/kg) was performed to inhibit ERS. Serum samples (n=30) and liver tissue samples (n=6) were collected from healthy controls, chronic hepatitis B (CHB) patients, and hepatitis B virus-associated liver failure (HBV-LF) patients; ELISA was used to measure the serum level of DDX3X, and qRT-PCR/Western Blot was used to analyze the expression of targets in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group of mice, the expression of DDX3X in the liver of mice induced by ConA was significantly increased after liver injury (P<0.05), and hepatocyte-specific DDX3X knockout increased the 72-hour survival rate of mice by 55% (compared with 20% in the DDX3Xfl/fl group), with significant reductions in the serum levels of ALT and AST (P<0.000 1) and the expression levels of the ERS markers GRP78 and CHOP (P<0.05). After ERS was inhibited by 4-PBA, there was alleviation of liver injury (with reductions in ALT and AST, P <0.001) and a reduction in DDX3X expression (P<0.01). The analysis of clinical samples showed that the mRNA and protein expression levels of liver DDX3X in CHB patients and HBV-LF patients were significantly higher than those in healthy controls (all P<0.01), and there was a significant increase in the serum level of DDX3X in HBV-LF patients (P<0.000 1). ConclusionDDX3X exacerbates ILI by regulating the ERS-dependent apoptotic pathway (GRP78/CHOP), and its expression is associated with the progression of hepatitis B. Therefore, it can be used as a potential therapeutic target.

Objective:
To investigate the clinical effects of sinus elevation surgery and implant restorationdue to insufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis (OMS) and to provide a reference for use in clinical practice.
Methods:
This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-five teeth were extracted from patients with OMS in the maxillary posterior area (the study group). Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group. Forty-eight teeth were extracted from patients without "OMS" in the maxillary posterior area (the control group), and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group. In the study group, 13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation, and the other 32 cases were addressed with crest-approach sinus elevation. In the control group, 8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation. Restorations were placed 6 to 8 months after surgery. The patients were followed up 21 days, 3 months, and 8 months after implantation and every 6 months after the placement of the restorations. The sinus bone gain (SBG), apical bone height (ABL) and marginal bone loss (MBL) were statistically analyzed 24 months after the restoration.
Results:
The average preoperative mucosal thickness in the 45 patients in the study group was (1.556 ± 0.693) mm, which was significantly larger than that in the control group (1.229 ± 0.425) mm (P<0.001). There were no perforations in either group. Twenty-four months after restoration, there was no significant difference in the SBG, ABH or MBL between the two groups (P>0.05).
Conclusion
After the extraction of teeth from patients with OMS, the inflammation of the maxillary sinus decreased, and the bone height and density in the edentulous area were restored to a certain degree. The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective:
To investigate the effect of G protein-coupled receptor 108(GPR108) gene knockout on systemic inflammation in lipopolysaccharide(LPS)-induced sepsis mice.
Methods:
Male C57BL/6 mice and GPR108 gene knockout mice were randomly divided into 4 groups: WT group, WT-LPS group, KO group, KO-LPS group. The physiological characteristics of mice in different groups were observed, and the morphological changes of liver and lung tissues were observed. Macrophages were extracted from bone marrow and subjected to flow cytometry to detect their M1 polarization status. The expression levels of IL-6 in liver and lung tissues, macrophages, and serum were also measured.
Results:
KO-LPS group mice showed significant liver and lung tissue damage, with a significantly greater number of bone marrow-derived macrophages polarizing towards M1 in the KO-LPS group compared to the WT-LPS group. Additionally, at the tissue, cellular, and serum levels, the expression of IL-6 in the KO-LPS group mice was significantly higher than that in the WT-LPS group mice(P<0.05).
Conclusion
During the systemic inflammatory infection induced by LPS in mice, the lack of GPR108 exacerbates the systemic inflammatory response. GPR108 has an inhibitory effect on the inflammatory response in mice with LPS-induced sepsis.
