OBJECTIVE To explore the mechanism of action of Qingre huatan huoxue decoction against atherosclerosis （AS）based on macrophage polarization. METHODS Using atorvastatin served as the positive control， the drug-containing serum of the Qingre huatan huoxue decoction was prepared to treat RAW264.7 macrophages. Macrophage viability， apoptosis rate， and the fluorescence intensities of CD86 and CD206 were measured， along with the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. Apolipoprotei n E-deficient （ApoE －/－ ） mice （AS model mice） fed with a high-fat diet were randomly assigned to model group， atorvastatin group （2.6 mg/kg）， and low-， medium- and high-dose groups of Qingre huatan huoxue decoction （90， 180， 360 mg/kg）， respectively. C57BL/6J mice fed with a standard diet served as the normal control group， with 10 mice per group. The treatment group mice were administered the corresponding drugs intragastrically， once daily， for 8 consecutive weeks. Serum levels of TNF-α and IL-1β were measured in all groups. Lipid deposition in the aorta （assessed by the percentage of plaque in the entire aorta and aortic root） and morphological changes in the aortic root were observed. Expression levels of CD86 and CD206 in aortic tissue， as well as the protein expression levels of inducible nitric oxide synthase （iNOS）， arginase-1 （Arg-1）， AMP-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， and peroxisome proliferator-activated receptor γ （PPAR-γ） in aortic tissues were all detected. RESULTS Cell experiment results showed that， at concentrations of 5-100 μg/mL， the drug-containing serum of the Qingre huatan huoxue decoction significantly increased RAW264.7 cell viability （ P ＜0.05）. The drug-containing serum of the Qingre huatan huoxue decoction at concentrations of 10， 50， and 100 μg/mL， along with atorvastatin， significantly reduced apoptosis rates， CD86 fluorescence intensity， and TNF-α and IL-1β levels in RAW264.7 cells， while markedly enhancing CD206 fluorescence intensity （ P ＜0.05）. Animal experiment results showed that， compared with the model group， all dosage groups of Qingre huatan huoxue decoction and the atorvastatin group showed significantly reduced/down-regulated levels of TNF-α and IL-1β in serum， along with decreased aortic total and root plaque percentages， CD86 expression， and iNOS protein expression. CD206 expression and Arg-1， p-AMPK/AMPK， PPAR-γ protein expression were significantly up-regulated （ P ＜0.05）. Pathological morphology of the aorta showed varying degrees of improvement. CONCLUSIONS The formula of Qingre huatan huoxue decoction exerts its anti-AS effects by regulating macrophage polarization， increasing the proportion of M2 macrophages， thereby effectively inhibiting AS plaque formation and reducing inflammatory responses.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Instrument separation is a critical complication during root canal therapy, impacting treatment success and long-term tooth preservation. The etiology of instrument separation is multifactorial, involving the intricate anatomy of the root canal system, instrument-related factors, and instrumentation techniques. Instrument separation can hinder thorough cleaning, shaping, and obturation of the root canal, posing challenges to successful treatment outcomes. Although retrieval of separated instrument is often feasible, it carries risks including perforation, excessive removal of tooth structure and root fractures. Effective management of separated instruments requires a comprehensive understanding of the contributing factors, meticulous preoperative assessment, and precise evaluation of the retrieval difficulty. The application of appropriate retrieval techniques is essential to minimize complications and optimize clinical outcomes. The current manuscript provides a framework for understanding the causes, risk factors, and clinical management principles of instrument separation. By integrating effective strategies, endodontists can enhance decision-making, improve endodontic treatment success and ensure the preservation of natural dentition.

Hepato-pancreato-biliary diseases (HPBD) are often complicated. The diagnosis and treatment of HPBD involve many disciplines. The malignant degree of hepatobiliary pancreatic system is high, and the prognosis of patients is poor. The multidisciplinary team (MDT) brings specialists from different disciplines together to make a comprehensive and individualized treatment for patients. MDT is emerging in HPBD in recent years. MDT helps improve the accuracy of diagnosis and prognosis. However, there are still some controversies and obstacles in the application of MDT for patients with HPBD. We reviewed the development, current status and experience of MDT in the field of HPBD, analyze the current controversy and obstacles, and providing reference for its future application.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

Objective:To explore the efficacy of secondary targeted percutaneous vertebroplasty (PVP) for the treatment of refracture of injured vertebrae after vertebral augmentation for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was performed on the clinical data of 25 patients with refracture of injured vertebrae after vertebral augmentation for OVCF admitted to Honghui Hospital, Xi′an Jiaotong University from January 2019 to January 2022, including 10 males and 15 females, aged 62-86 years [(73.8±5.2)years]. The fractured segments involved T 10 in 1 patient, T 11 in 2, T 12 in 10, L 1 in 10 and L 2 in 2. All the patients were treated with secondary targeted PVP. The operation time and the amount of bone cement injected were recorded. The visual analogue scale (VAS) of lower back, Oswestry disability index (ODI), vertebral body index (VBI) and kyphotic angle (KA) were compared before surgery, at 1 day, 6 months after surgery and at the last follow-up. Odom criteria were used to evaluate the efficacy of the surgical procedure at the last follow-up. The intraoperative bone cement leakage and new vertebrae fracture during follow-up were observed. Results:All the patients were followed up for 23-59 months [(36.8±7.6)months]. The operation time was 35-60 minutes [(42.6±5.2)minutes], with the amount of bone cement injected for 3-5 ml [(3.6±0.8)ml]. The VAS scores of lower back at 1 day, 6 months after surgery and at the last follow-up were 3.1(2.0, 4.0)points, 1.7(1.0, 2.0)points and 0.6(0.0, 1.0)points respectively, significantly lower than 7.6(7.0, 9.0)points before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The ODI values at 1 day, 6 months after surgery and at the last follow-up were (49.5±5.9)%, (28.5±4.6)% and (19.2±4.8)% respectively, significantly lower than (78.8±6.8)% before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The VBI values at 1 day, 6 months after surgery and at the last follow-up were (76.6±4.5)%, (76.3±4.0)% and (76.1±3.8)% respectively, significantly higher than (58.9±5.8)% before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). The KA values at 1 day, 6 months after surgery and at the last follow-up were (12.4±2.7)°, (12.6±2.5)° and (12.8±2.9)° respectively, significantly lower than (20.8±3.6)° before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). According to the Odom criteria, 20 patients were rated excellent and 5 good at the last follow-up, with an excellent and good rate of 100%. Intraoperative asymptomatic bone cement leakage occurred in 3 patients (12%), including 2 with intervertebral leakage and 1 with lateral vertebral leakage. No adjacent vertebral body or other vertebral fracture was observed during the follow-up. Conclusions:For patients with refracture of injured vertebrae after vertebral augmentation for OVCF, the secondary targeted PVP has advantages of attenuation of the lower back pain, improvement of the quality of life, restoration of the height of refractured vertebrae, correction of the local kyphosis, and a low incidence of complications.
