Temporal interference (TI) is a form of stimulation that epitomizes an innovative and non-invasive approach for profound neuromodulation of the brain, a technique that has been validated in mice. Yet, the thin cranial bone structure of mice has a marginal influence on the effect of the TI technique and may not effectively showcase its effectiveness in larger animals. Based on this, we carried out TI stimulation experiments on rats. Following the TI intervention, analysis of electrophysiological data and immunofluorescence staining indicated the generation of a stimulation focus within the nucleus accumbens (depth, 8.5 mm) in rats. Our findings affirm the viability of the TI methodology in the presence of thick cranial bones, furnishing efficacious parameters for profound stimulation with TI administered under such conditions. This experiment not only sheds light on the intervention effects of TI deep in the brain but also furnishes robust evidence in support of its prospective clinical utility.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:
To investigate the mechanism by which serum amyloid P component (SAP) alleviates periodontitis in mice, providing an experimental basis to establish SAP as a novel therapeutic agent for periodontitis.
Methods:
Ethical approval was obtained from the Institutional Animal Ethics Committee. Periodontitis models were established in wild-type (WT) mice and SAP-transgenic (SAP-Tg) mice, divided into four groups: WT control (WT group), WT periodontitis (WT+P group), SAP-Tg control (Tg group), and SAP-Tg periodontitis (Tg+P group). On day 7, the mice were euthanized, and periodontal tissues, teeth, and alveolar bone were collected. SAP protein expression was detected by enzyme-linked immunosorbent assay (ELISA). Micro-CT and HE staining were used to measure alveolar bone resorption (distance from the cementoenamel junction to the alveolar bone crest). Tartrate-resistant acid phosphatase (TRAP) staining was performed to assess osteoclast number, and immunohistochemistry (IHC) was employed to evaluate macrophage infiltration. The expression levels of inflammatory cytokines including interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured by qRT-PCR. Oral microorganism composition was analyzed using 16S ribosomal RNA (16S rRNA) gene sequencing. Additionally, macrophages from WT and SAP-Tg mice were isolated to establish an in vitro inflammation model, divided into WT+LPS and Tg+LPS groups. The expression of macrophage polarization-related genes including inducible nitric oxide synthase (iNOS), CD86, CD163, and CD206) were assessed by qRT-PCR. After the induction of osteoclast differentiation, TRAP staining was performed.
Results:
ELISA results demonstrated that periodontal tissues from Tg+P group mice exhibited higher levels of SAP expression compared to the WT+P group. Micro-CT and HE staining analyses revealed that the Tg+P group showed reduced alveolar bone resorption, indicated by a shorter distance between the cementoenamel junction and alveolar bone crest, compared to the WT+P group. Furthermore, TRAP staining results indicated a decrease in osteoclast numbers in the Tg+P group compared to the WT+P group. IHC and qRT-PCR results indicated reduced macrophage infiltration and decreased expression of IL-1β, IL-6, and TNF-α in the Tg+P group. Oral microorganism sequencing showed no significant difference in periodontitis-associated pathogenic bacteria between WT+P and Tg+P groups. In vitro experiments demonstrated that compared to the WT+LPS group, the Tg+LPS group exhibited downregulated M1 macrophage markers (iNOS and CD86) and upregulated M2 macrophage markers (CD163 and CD206). TRAP staining confirmed fewer osteoclasts in the Tg+LPS group.
Conclusion
SAP overexpression effectively alleviates periodontitis severity in mice by inhibiting M1 macrophage polarization, reducing pro-inflammatory cytokine expression, and suppressing osteoclast differentiation, thereby attenuating alveolar bone resorption.

BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50%.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21%(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

ObjectiveTo investigate the influence of entecavir (ETV) versus tenofovir alafenamide fumarate (TAF) on renal function in previously untreated patients with chronic hepatitis B (CHB). MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023, and according to the antiviral drug used, they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data, propensity score matching (PSM) was used for matching and analysis at a ratio of 2∶1, and the two groups were compared in terms of estimated glomerular filtration rate (eGFR) and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48, the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function, and the receiver operating characteristic (ROC) curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function, and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching, there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group (all P>0.05), with an eGFR level of 112.29±9.92 mL/min/1.73 m2 in the ETV group and 114.72±12.15 mL/min/1.73 m2 in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups, and compared with the TAF group at week 48, the ETV group had a significantly lower eGFR (106.42±14.12 mL/min/1.73 m2 vs 112.25±13.44 mL/min/1.73 m2, t=-2.422, P=0.017) and a significantly higher incidence rate of abnormal renal function (17.00% vs 4.00%, χ2=5.092, P=0.024). After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients, the univariate analysis showed that there were significant differences between the two groups in age (Z=-2.039, P=0.041), treatment drug (ETV/TAF) (χ2=5.092, P=0.024), and baseline eGFR level (t=4.023, P<0.001), and the multivariate Logistic regression analysis showed that baseline eGFR (odds ratio [OR]=0.896, 95% confidence interval [CI]: 0.841 — 0.955, P<0.001) and treatment drug (OR=5.589, 95%CI: 1.136 — 27.492, P=0.034) were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients, with a cut-off value of 105.24 mL/min/1.73 m2, a sensitivity of 73.68%, and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m2 had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m2 (χ2=22.330, P<0.001), and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group (χ2=4.961, P=0.026). With the initiation of antiviral therapy, both the ETV group and the TAF group had a significant reduction in eGFR (F=5.259, P<0.001), but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 (t=-2.422, P=0.017); both the baseline eGFR≤105.24 mL/min/1.73 m2 group and the baseline eGFR>105.24 mL/min/1.73 m2 group had a significant reduction in eGFR (F=5.712, P<0.001), and there was a significant difference in eGFR between the two groups at baseline and weeks 12, 24, 36, and 48 (t=-13.927, -9.780, -8.835, -9.489, and -8.953, all P<0.001). ConclusionFor CHB patients initially treated with ETV or TAF, ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

Objective:To investigate the clinical efficacy of combination of a Flow-through anterolateral thigh myocutaneous flap with a contralateral great saphenous vein grafting in reconstruction of Gustilo ⅢC foot and ankle injury in emergency surgery.Methods:This retrospective study analysed the clinical data of 9 patients who were admitted in the Department of Wound Repair Surgery, Suzhou Ruihua Orthopaedic Hospital between September 2021 and October 2023. All patients were diagnosed with Gustilo ⅢC foot and ankle injury and met the predefined inclusion criteria. The average age of the patients was 45 (26-64) years. The mean of Mangled Extremity Severity Score (MESS) was 8.2 points, with a range from 5 to 10 points. The wound area after debridement ranged from 15.5 cm×6.0 cm to 24.5 cm×12.5 cm, with the vascular occlusion or defect at 4.0-20.0 (mean, 6.3) cm in length. The size of the flap was 16.5 cm×7.0 cm-25.5 cm×13.5 cm. During surgery, segments of the great saphenous vein were excised in the length of 5.0-21.0 cm, at an approximately 6.5 cm in length. The Flow-through anterolateral thigh myocutaneous flap was employed to reconstruct the soft tissue defect and to establish vascular connections between the anterior or posterior tibial arteries and veins, with the vessels carried by the flap. Additionally, the contralateral great saphenous vein was taken to bridge the posterior or anterior tibial arteries and veins. Follow-ups were carried out by outpatient visits, telephone calls and WeChat interviews. The flap viability, limb blood circulation, wound healing at both donor and recipient sites, as well as functional recovery of the affected limbs was observed. Sensation recovery of the flap was assessed according to the rating standard established by the British Medical Research Council (BMRC) , while the function recovery of foot and ankle was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale.Results:All flaps successfully survived without vascular complication. Eight affected limbs were effectively cured, while a calf that had an infection and necrosis of a long segment of tibia and fibula was amputated below-the-knee in the stage-II surgery. One of the donor sites of flap was covered with a medium-thickness skin graft from lower abdomen due to the large size of the flap, while the other donor sites were directly sutured and healed at first intention. One patient developed postoperative bone infection, which was successfully treated through re-debridement and antibiotic bone cement filling. Another patient experienced partial necrosis at the distal hallux due to a prolonged limb ischemia, and a stump repair surgery was performed. All patients were entered into the postoperative follow-up for 15.3 (6-24) months. At the final follow-up visit, satisfactory colour and texture were observed on all flaps, although minor oedema was present. Donor sites healed well and the donor limb function was not affected. Sensory evaluation rated S 2 in 5 flaps and S 3 in 3 flaps according to BMRC. Functional assessment of foot and ankle of the affected limb yielded excellent in 2 patients, good in 5 patients and fair in 1 patient according to AOFAS. Conclusion:Flow-through anterolateral thigh myocutaneous flap combined with a contralateral great saphenous vein grafting enables one-stage reconstruction for soft tissue defect and blood circulation of the affected limb. It is a good method in the treatment of Gustilo ⅢC foot and ankle injury in emergency surgery.

Objective:To explore the clinical effect of the whole-process management scheme of daytime minimally invasive liver resection surgery based on the enhanced recovery after surgery (ERAS) concept.Methods:This is a retrospective case series study. The data of 55 patients who underwent minimally invasive daytime liver resection surgery under the ERAS concept at the Department of General Surgery,Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from January 2023 to August 2024. There were 22 males and 33 females;aged (48.2±15.1) years (range: 16 to 77 years). All patients were classified as Grade 2 according to the American Society of Anesthesiologists physical status classification. Among them, 7 cases were complicated with liver cirrhosis and 10 cases had fatty liver. A multidisciplinary team was formed, consisting of surgeons, anesthesiologists, rehabilitation physicians, psychologists, pharmacists, acute pain management team, operating room nurses, day surgery ward nurses, and ERAS specialized nurses. After strict evaluation by surgeons and anesthesiologists, patients suitable for daytime liver resection surgery were implemented with the ERAS whole-process management plan for liver resection on the basis of routine nursing care.Results:Among the 55 patients, 50 were discharged smoothly within 48 hours, while 5 were transferred to specialized departments for further treatment due to not meeting the discharge criteria, with a smooth daytime discharge rate of 90.9%. Among the 50 patients, 30 underwent laparoscopic surgery and 20 underwent robotic-assisted surgery. The surgery time was (91.6±28.2)minutes(range:45 to 165 minutes), with the intraoperative blood loss of only (30.5±25.5)ml(range:5 to 100 ml). Pathological examination results showed that among the 50 patients, 13 cases had hepatocellular carcinoma, 21 cases had hepatic hemangioma, 4 cases had hepatic cyst, 8 cases had focal nodular hyperplasia, 1 case had low-grade dysplastic nodule, 1 case had hepatolithiasis, 1 case had lymphoma, and 1 case had vascular, fibrous and lymphoid tissue proliferation. There were 44.0% patients who were able to get out of bed on the day of surgery. The hospital stay was (1.8±0.4)days(range:1 to 2 days), and the hospitalization cost was (34 499±20 330)yuan(range:11 724 to 73 488 yuan). No complications requiring special treatment outside the conventional pathway were observed during the hospital stay and follow-up period. At the 2-week outpatient follow-up, no significant abnormalities were found in all patients, and the wound healing was good.Conclusions:The daytime liver resection surgery based on the ERAS whole-process management plan has shown good feasibility in clinical practice. It helps to simplify medical process, shorten hospital stay, and reduce medical costs.

Aim To explore the mechanism of baicalin combined with heat stimulation in treating acute lym-phoblastic leukemia(ALL)based on network pharma-cology and in vitro experiments.Methods The CCK-8 assay was used to screen the suitable conditions for heat stimulation to interfere ALL cell lines Jurkat,CCRF-CEM,Hut-78 and a normal lymphocyte HMy2.CIR,and the effects of baicalin combined with heat stimulation on the proliferation of three ALL cell lines and a normal lymphocyte were tested.The key targets of baicalin combined with fever stimulation for the treatment of ALL were obtained based on network phar-macological analysis,and the potential mechanisms were predicted by gene ontology(GO)annotation and kyoto encyclopedia of genes and genomes(KEGG)en-richment.The expression levels of TNF-α,AKT1,TYMS and CASP3 mRNA in ALL cell lines Jurkat and CCRF-CEM were examined by RT-qPCR with baicalin alone and baicalin combined with heat stimulation.Results The optimal conditions for heat stimulation to intervene ALL cells were 41 ℃ for 24 h,and heat stimulation combined with baicalin synergistically inhibited the growth of ALL cell lines and effectively reduced the cy-totoxicity of baicalin.Based on the network pharmaco-logical analysis,55 intersecting targets of baicalin with ALL diseases and 77 intersecting targets of baicalin with fever were obtained.The results of GO annotation and KEGG enrichment suggested that baicalin com-bined with fever stimulation to intervene ALL might be associated with influencing intracellular reactive oxygen species metabolism,DNA transcription and apoptotic processes involved in cysteine enzymes.Apoptosis,TNF and IL-17 signaling pathways were the key pathways for baicalin combined with heat stimulation in treating ALL.Under heat stimulation at 41 ℃ using SDHA gene as housekeeping gene,in vitro experiments showed that baicalin significantly up-regulated the expression of TNF-α and CASP3,and down-regulated the expression of TYMS in ALL cells.Conclusions Based on net-work pharmacologic analyses and in vitro experiments,baicalin combined with heat stimulation can regulate TNF-α and CASP3 gene levels in ALL cells and de-stroy cellular structure to promote cell apoptosis,thus synergistically treating ALL.
