Objective A scoping review of research on mobile glucose management in pregnant women with gestational diabetes mellitus was conducted to provide references for clinical providers to conduct mobile glucose management and related research.Methods Based on Arksey and O'Malley's scoping review reporting framework,JBI Library,Cochrane Library,PubMed,Web of Science,Embase,CINAHL Complete,CBM,China National Knowledge In-frastructure(CNKI),and Wanfang Database were retrieved.The search time frame was from the establishment of the databases to February 14,2023.The included literature was screened,summarized and analyzed.Results A total of 65 publications from 11 countries were included,among which 38 were randomized controlled trials,27 were experimental studies.The vehicles relied on for mobile glucose management in gestational diabetes mainly included APPs,remote monitoring systems,professional websites,and social platforms,which could provide health education,glucose management monitoring and recording,social support,and glucose management follow-up and reminders to pregnant women.Most of the studies focus on the glucose index and drug use,pregnancy outcome,self-management,quality of life,user experience and resource cost of pregnant women.Conclusion Mobile glucose management carriers are geographically specific and have a positive effect on glucose control in gestational diabetes.Future studies need to further develop localized mobile glucose management intervention protocols and conduct more high-quality randomized controlled studies to verify their effectiveness.

Objective:To investigate the effect and mechanism of the V-set and immunoglobulin domain-containing 4 ( VSIG4 ) gene mutation on the function of microglia in retinitis pigmentosa (RP). Methods:Localization of VSIG4 in the retina was detected by immunofluorescence.HMC3 cells (human microglial cells) were transfected with wild-type (Len-WT) VSIG4 gene, mutant type (Len-Mut) VSIG4 gene and empty vector virus (Len-Cont) and stimulated by the presence or absence of lipopolysaccharide (LPS), then divided into control group, LPS-Len-Mut group, LPS-Len-WT group, LPS-Len-Cont group, Len-Mut group, Len-WT group and Len-Cont group.The mRNA expression levels of the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by real-time fluorescence quantitative PCR.Protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), glutathione peroxidase 4 (GPX4), nuclear transcription factor-κB (NF-κB) p65 subunit (P65), and phosphorylated P65 (PP65) were detected by Western blot.Cell phagocytic function was detected by phagocytosis assay.Cell migration ability was detected by cell scratch and transwell migration assay.LPS- stimulated HMC3 cells were co-cultured with 661W cells (mouse retinal photoreceptor cells), and the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) proteins of the cells were detected by Western blot.The number of apoptotic cells was determined by apoptosis assay. Results:VSIG4 was localized to microglia in mouse retina.The real-time fluorescence quantitative PCR results showed that compared with LPS-Len-WT group, the relative expression levels of IL-1β and TNF-α mRNA in HMC3 cells were significantly increased in LPS-Len-Mut group (both at P<0.05).The Western blot results showed that compared with LPS- Len-WT group, the protein expression levels of Nrf2, HO-1, and GPX4 in HMC3 cells were significantly reduced in LPS-Len-Mut group, and the PP65/P65 ratio was significantly increased (all at P<0.05).The phagocytic experiment results showed that the phagocytic rates of HMC3 cells in Len-Cont group, LPS-Len-Cont group, LPS-Len-WT group, and LPS-Len-Mut group were (35.67±3.22)%, (63.67±10.07)%, (84.00±3.46)%, and (64.67±2.31)%, respectively, showing a statistically significant difference ( F=59.06, P<0.001).Compared with LPS-Len-WT group, the phagocytic rate of HMC3 cells was significantly reduced in LPS-Len-Mut group ( P<0.05).The results of cell scratch and transwell migration assay showed that compared with LPS-Len-WT group, the migration rate of HMC3 cells at 24 and 48 hours and the number of invading cells per unit area at 24 hours were significantly reduced in LPS-Len-Mut group (all at P<0.05).Compared with LPS-Len-WT group, the expression ratio of Bax/Bcl-2 protein and the number of cell apoptosis were significantly increased in the LPS-Len-Mut group under the co-culture system (both at P<0.05). Conclusions:VSIG4 is localized to mouse retinal microglia.When the VSIG4 gene in RP mutates, HMC3 cells under LPS stimulation exhibit a series of changes, including activation of the NF-κB signaling pathway, decreased activation of the Nrf2/HO-1 signaling pathway, increased secretion of inflammatory cytokines, reduced phagocytic and migratory abilities, and increased cell apoptosis in co-culture systems.

Objective To summarize the liver biopsy and clinical features of patients with liver injury of unknown origin,and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin.Methods A retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital,Xiamen University,from January 2018 to February 2023.According to the proportion of the patients with different final diagnoses,the patients were divided into autoimmune liver disease(AILD)group,metabolic associated fatty liver disease(MAFLD)group,drug-induced liver injury(DILI)group,alcoholic liver disease(ALD)group,and unknown group.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the Bonferroni analysis or the Dunnett'T3 test was used for further comparison between two groups;the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups;the Fisher's exact test was used for comparison of categorical data between multiple groups.Results All 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission,among whom 90 patients(95.7%)had a confirmed diagnosis based on liver biopsy and clinical features.There were 43 patients(45.7%)with AILD,21(22.3%)with MAFLD,15(16.0%)with DILI,6(6.4%)with ALD,1(1.1%)with AILD and MAFLD,1(1.1%)with hemochromatosis,1(1.1%)with Budd-Chiari syndrome,1(1.1%)with congenital hepatic fibrosis,and 1(1.1%)with idiopathic portal hypertension,while 4 patients(4.3%)still had an unknown etiology after liver biopsy.There were significant differences between the patients with top five diagnoses in age(F=4.457,P<0.05),body mass index(BMI)(F=3.245,P<0.05),aspartate aminotransferase(AST)(H=11.128,P<0.05),gamma-glutamyl transpeptidase(GGT)(H=24.789,P<0.05),alkaline phosphatase(ALP)(H=26.013,P<0.05),IgG(H=19.099,P<0.05),IgM(H=21.263,P<0.05),AMA-M2 positive rate(P<0.05),and ANA positive rate(P<0.05).Compared with the MAFLD group,the AILD group had significantly higher age,AST,GGT,and ALP and a significantly lower BMI;compared with the MAFLD group and the DILI group,the AILD group had significant increases in IgG and IgM;the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups.Conclusion AILD,MAFLD,and DILI are the most common causes in patients with liver injury of unknown origin.Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin,but it is still needed to make a comprehensive analysis based on clinical history,different types of liver injury,laboratory markers,and imaging data.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Proprotein Convertase Subtilisin/Kexin 9 (PCSK9) inhibitor has become a new drug for the treatment of hypercholesterolemia and atherosclerotic cardiovascular disease. Recent studies have shown that the mechanism of PCSK9 in atherosclerotic cardiovascular disease is very complex, which is closely related to the increase of plasma low-density lipoprotein cholesterol level, apoptosis, autophagy, inflammation, foam cell formation and vascular smooth muscle cell calcification, which will help us better understand the " multiple effects" of PCSK9 inhibitors. This review aims to analyze the research status of PCSK9 in molecular structure, cell function and cardiovascular disease treatment, which will further consolidate the success of new treatment strategies for atherosclerosis.

OBJECTIVE: To investigate the effect of Akt2 inhibitor on macrophage polarization in the periapical tissue in a rat model of periapical inflammation. METHODS: Rat models of periapical inflammation were established in 28 normal SD rats by opening the pulp cavity of the mandibular first molars, followed by injection of normal saline and Akt2 inhibitor into the left and right medullary cavities, respectively. Four rats without any treatment served as the healthy control group. At 7, 14, 21 and 28 days after modeling, 7 rat models and 1 control rat were randomly selected for observation of inflammatory infiltration in the periapical tissues by X-ray and HE staining. Immunohistochemistry was used to detect the expression and localization of Akt2, macrophages and the inflammatory mediators. RT-PCR was performed to detect the mRNA expressions of Akt2, CD86, CD163, inflammatory mediators, miR-155-5p and C/EBPβ to analyze the changes in macrophage polarization. RESULTS: X-ray and HE staining showed that periapical inflammation was the most obvious at 21 days after modeling in the rats. Immunohistochemistry and RT-PCR showed that compared with those in the control rats, the expressions of Akt2, CD86, CD163, miR-155-5p, C/EBPβ, and IL-10 increased significantly in the rat models at 21 days (P < 0.05). Compared with saline treatment, treatment with the Akt2 inhibitor significantly decreased the expression levels of Akt2, CD86, miR-155-5p and IL-6 and the ratio of CD86⁺M1/CD163⁺M2 macrophages (P < 0.05) and increased the expression levels of CD163, C/EBPβ and IL-10 in the rat models (P < 0.05). CONCLUSION Inhibition of Akt2 can delay the progression of periapical inflammation in rats and promote M2 macrophage polarization in the periapical inflammatory microenvironment possibly by reducing miR-155-5p expression and activating the expression of C/EBPβ in the Akt signaling pathway.

Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score ≥ Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Digital guided therapy (DGT) has been advocated as a contemporary computer-aided technique for treating endodontic diseases in recent decades. The concept of DGT for endodontic diseases is categorized into static guided endodontics (SGE), necessitating a meticulously designed template, and dynamic guided endodontics (DGE), which utilizes an optical triangulation tracking system. Based on cone-beam computed tomography (CBCT) images superimposed with or without oral scan (OS) data, a virtual template is crafted through software and subsequently translated into a 3-dimensional (3D) printing for SGE, while the system guides the drilling path with a real-time navigation in DGE. DGT was reported to resolve a series of challenging endodontic cases, including teeth with pulp obliteration, teeth with anatomical abnormalities, teeth requiring retreatment, posterior teeth needing endodontic microsurgery, and tooth autotransplantation. Case reports and basic researches all demonstrate that DGT stand as a precise, time-saving, and minimally invasive approach in contrast to conventional freehand method. This expert consensus mainly introduces the case selection, general workflow, evaluation, and impact factor of DGT, which could provide an alternative working strategy in endodontic treatment.

Osteoporosis (OP) is a systemic skeletal disease that primarily affects the elderly population, which greatly increases the risk of fractures. Here we report that Kindlin-2 expression in adipose tissue increases during aging and high-fat diet fed and is accompanied by decreased bone mass. Kindlin-2 specific deletion (K2KO) controlled by Adipoq-Cre mice or adipose tissue-targeting AAV (AAV-Rec2-CasRx-sgK2) significantly increases bone mass. Mechanistically, Kindlin-2 promotes peroxisome proliferator-activated receptor gamma (PPARγ) activation and downstream fatty acid binding protein 4 (FABP4) expression through stabilizing fatty acid synthase (FAS), and increased FABP4 inhibits insulin expression and decreases bone mass. Kindlin-2 inhibition results in accelerated FAS degradation, decreased PPARγ activation and FABP4 expression, and therefore increased insulin expression and bone mass. Interestingly, we find that FABP4 is increased while insulin is decreased in serum of OP patients. Increased FABP4 expression through PPARγ activation by rosiglitazone reverses the high bone mass phenotype of K2KO mice. Inhibition of FAS by C75 phenocopies the high bone mass phenotype of K2KO mice. Collectively, our study establishes a novel Kindlin-2/FAS/PPARγ/FABP4/insulin axis in adipose tissue modulating bone mass and strongly indicates that FAS and Kindlin-2 are new potential targets and C75 or AAV-Rec2-CasRx-sgK2 treatment are potential strategies for OP treatment.
