Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

ObjectiveTo observe the impacts of electroacupuncture （EA） on the expression of hippocampal brain-derived neurotrophic factor （BDNF） and acetylated histone （AcH3） in the rat model of spared nerve injury （SNI）， so as to explore the analgesic and antidepressant effects of EA. MethodsTwenty-four Male SD rats were randomly divided into 4 groups， with 6 in each group. SNI was used to establish the model of pain and depression. All the groups were intervened one week after SNI surgery and persisted 5 weeks. The EA group was treated with EA （2 Hz） for 30 min every other day and imipramine drug group （IMP） group with peritoneal imipramine injection （10 mg/kg） per day. The sham surgery group （SS） and model group （SNI） received the same grasping stimulation. The paw mechanical withdrawal threshold （PWT） test was performed before the SNI surgery， 1， 2， 3， 4， 5， and 6 weeks after surgery， respectively. The forced swimming test （FST） and the sucrose preference test （SPT） were performed 6 weeks after SNI surgery. The Western blot method was employed to detect the expression of BDNF and AcH3 from the rat hippocampal tissue at the end of the behavioral tests. ResultsCompared with the SS group， the SNI group had significantly decreased PWT and sucrose consumption， prolonged FST immobility time （all P<0.01）， down-regulated BDNF and AcH3 expression （P<0.05 & P<0.01） in the hippocampus， which indicated the successful construction of the pain-depression model. Compared with the SNI group， 6 weeks after SNI surgery， the EA and IMP groups had significantly increased PWT and sucrose consumption， and reduced FST immobility time （all P<0.01）； the EA group had up-regulated BDNF and AcH3 expression （both P<0.05） in the hippocampus， the IMP group had up-regulated AcH3 （P<0.05） expression but no difference in BDNF expression. ConclusionEA could relieve pain and depressive behavioral symptoms in SNI rats. And its analgesic and antidepressant mechanisms may relate to the up-regulation of hippocampal AcH3 and BDNF expression.

Objective: To evaluate the effectiveness of a risk-adapted colorectal cancer screening strategy constructed utilizing genetic and environmental risk score (ERS). Methods: A polygenic risk score (PRS) was constructed based on 20 previously published single nucleotide polymorphisms for colorectal cancer in East Asian populations, using 2 160 samples with MassARRAY test results from a multicenter randomized controlled trial of colorectal cancer screening in China. The ERS was calculated using the Asia-Pacific Colorectal Screening Score system. Logistic regression was used to analyze the association between PRS alone and PRS combined with ERS and colorectal neoplasms risk, respectively. We also designed a risk-adapted screening strategy based on PRS and ERS (high-risk participants undergo a single colonoscopy, low-risk participants undergo an annual fecal immunochemical test, and those with positive results undergo further diagnostic colonoscopy) and compared its effectiveness with the all-acceptance colonoscopy strategy. Results: The high PRS group had a 26% increased risk of colorectal neoplasms compared with the low PRS group (OR=1.26, 95%CI: 1.03-1.54, P=0.026). Participants with the highest PRS and ERS were 3.03 times more likely to develop advanced colorectal neoplasms than those with the lowest score (95%CI: 1.87-4.90, P<0.001). As the risk-adapted screening simulation reached the third round, the detection rate of the PRS combined with ERS strategy was not statistically different from the all-acceptance colonoscopy strategy (8.79% vs. 10.46%, P=0.075) and had a higher positive predictive value (14.11% vs. 10.46%, P<0.001) and lower number of colonoscopies per advanced neoplasms detected (7.1 vs. 9.6, P<0.001). Conclusion: The risk-adapted screening strategy combining PRS and ERS helps achieve population risk stratification and better effectiveness than the traditional colonoscopy-based screening strategy.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective:To investigate the effect of intravenous anesthesia on the detection rate of lesions in diagnostic gastroscopy.Methods:A total of 9 071 subjects who underwent diagnostic gastroscopy at the Digestive Endoscopy Center of Yangzhou University Affiliated Hospital from March 2021 to February 2022 were selected. Data were collected from the gastroscopy quality control system, including age, gender, examination physician, Helicobacter pylori infection, examination method, withdrawal time, number of images left, number of biopsies, biopsy site, gastroscopy diagnosis, pathological diagnosis, etc. They were divided into anesthesia group and general group based on the examination method, and propensity score matching (PSM) was performed on the two groups of subjects. Excluding confounding factors, the detection of lesion location and lesion type in two groups of subjects was analyzed; Simultaneously, univariate and multivariate logistic regression analysis was used to analyze the influencing factors of the detection rate of precancerous lesions and malignant tumors in the upper gastrointestinal tract.Results:After PSM, 1 655 subjects were included in both groups. In terms of lesion location, the detection rate of gastric body lesions in the anesthesia group was higher than that in the general group ( P<0.05), and the detection rate of esophageal lesions in the anesthesia group was lower than that in the general group ( P<0.05); In terms of lesion types, the detection rate of precancerous lesions such as gastric polyps, mucosal protrusions, mucosal atrophy, and intestinal metaplasia in the anesthesia group was higher than that in the general group (all P<0.05). The results of logistic regression analysis showed that intravenous anesthesia was an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy ( OR=1.338, 95% CI: 1.070-1.674, P<0.05). Conclusions:Intravenous anesthesia is an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy, and can improve the detection rate of upper gastrointestinal lesions.

OBJECTIVE: To investigate the efficacy and safety of matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of young patients with multiple myeloma (MM). METHODS: The clinical data of 8 young patients (median age：46 years) with MM who underwent allo-HSCT from HLA-indentical sibling donors in the First Affiliated Hospital of Chongqing Medical University from June 2013 to September 2021 were collected, and their survival and prognosis were retrospectively analyzed. RESULTS: All the patients were successfully transplanted, and 7 patients could be evaluated the efficacy after transplantation. The median follow-up time was 35.2 (2.5-84.70) months. The complete response (CR) rate was 2/8 before transplantation and 6/7 after transplantation. Acute GVHD developed in 2 cases and extensive chronic GVHD developed in 1 case. Within 100 days, 1 case died of non-recurrent events, and 1-year and 2-year disease-free survival were 6 and 5 cases, respectively. At the end of follow-up, all the 5 patients who survived for more than 2 years survived, and the longest disease-free survival time has reached 84 months. CONCLUSION With the development of new drugs, HLA-matched sibling donor allo-HSCT may be a curable treatment for young patients with MM.

The present study investigated the mechanism of the Tibetan medicine Ershiwuwei Songshi Pills(ESP) against the liver injury induced by acetaminophen(APAP) in mice based on the kelch-like ECH-associated protein 1(Keap1)/nuclear transcription factor E2 related factor 2(Nrf2) and Toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB) p65 signaling pathways. Kunming mice were randomly divided into a blank control group, a model group, an N-acetyl-L-cysteine(NAC) group, and high-(400 mg·kg~(-1)), medium-(200 mg·kg~(-1)), and low-dose(100 mg·kg~(-1)) ESP groups. After 14 days of continuous administration, except for those in the control group, the mice were intraperitoneally injected with 200 mg·kg~(-1) APAP. After 12 h, the serum and liver tissues of mice were collected. Hematoxylin-eosin(HE) staining was performed on pathological sections of the liver, and the levels of aspartate aminotransferase(AST) and alanine aminotransferase(ALT) in the serum and the levels of glutathione(GSH), malondialdehyde(MDA), superoxide dismutase(SOD), catalase(CAT), myeloperoxidase(MPO), and total antioxidant capacity(T-AOC) in liver tissue homogenate were detected to observe and analyze the protective effect of ESP on APAP-induced liver injury in mice. The serum levels of tumor necrosis factor-alpha(TNF-α), interleukin-1 beta(IL-1β), and interleukin-6(IL-6) were determined by enzyme-linked immunosorbent assay(ELISA). The protein expression of Nrf2, Keap1, TLR4, and NF-κB p65 in the liver was determined by Western blot. Quantitative real-time was used to determine the mRNA expression of glutamate-cysteine ligase catalytic subunit(GCLC), glutamate-cysteine ligase regulatory subunit(GCLM), heme oxygenase-1(HO-1), and NAD(P)H dehydrogenase quinone 1(NQO-1) in the liver to explore the mechanism of ESP in improving APAP-induced liver damage in mice. As revealed by results, compared with the model group, the ESP groups showed improved liver pathological damage, decreased ALT and AST levels in the serum and MDA and MPO content in the liver, increased GSH, SOD, CAT, and T-AOC in the liver, reduced TNF-α and IL-6 levels in the serum, down-regulated expression of Keap1 in the liver cytoplasm and NF-κB p65 in the liver nucleus, up-regulated expression of Nrf2 in the liver nucleus, insignificant change in TLR4 expression, and elevated relative mRNA expression levels of antioxidant genes GCLC, GCLM, HO-1, and NQO-1. ESP can reduce the oxidative damage and inflammation caused by APAP, and the mechanism may be related to the Keap1/Nrf2 signaling pathway and the signal transduction factors on the TLR4/NF-κB p65 pathway.

This study aims to investigate the mechanism of the Tibetan medicine Ershiwuwei Shanhu Pills(ESP) in improving scopolamine-induced learning and memory impairment in mice based on Keap1/Nrf2/HO-1 signaling pathway. ICR mice were randomized into blank group, model group, low-dose(200 mg·kg~(-1)), medium-dose(400 mg·kg~(-1)), and high-dose(800 mg·kg~(-1)) ESP groups, and donepezil hydrochloride group. The learning and memory impairment was induced in mice by intraperitoneal injection of scopola-mine. The learning and memory abilities of mice were detected by Morris water maze test, and the damage of hippocampal neurons and cortical neurons was detected based on Nissl staining. The expression of neuron specific nuclear protein(NeuN) in hippocampus and cortex of mice was determined by immunofluorescence assay, and the content of acetylcholine(Ach) and the activity of acetylcholines-terase(AchE) in hippocampus of mice by kits. Moreover, the content of superoxide dismutase(SOD), malondialdehyde(MDA), catalase(CAT), and total antioxidant capacity(T-AOC) in serum of mice was detected. The content of Kelch-like ECH-associated protein 1(Keap1), nuclear factor erythroid 2-related factor 2(Nrf2), and heme oxygenase 1(HO-1) in hippocampus was determined by Western blot. The results showed that there were significant differences in the trajectory map of mice among different groups in the behavioral experiment. Moreover, the latency of ESP groups decreased significantly compared with that in the model group. The hippocampal neurons in the high-dose ESP group were significantly more than those in the model group and the cortical neurons in the high-dose and medium-dose ESP groups were significantly more than those in the model group. The expression of NeuN in the model group was significantly decreased compared with that in the blank group, and the expression in the ESP groups was significantly higher than that in the model group. The AchE activity and MDA level were significantly decreased, and Ach content and levels of SOD, CAT, and T-AOC in the ESP groups were significantly increased in the ESP groups compared with those in the model group. The expression of Keap1 in the model group was significantly increased compared with that in the blank group, and the Keap1 expression increased insignificantly in ESP groups compared with that in the model group. The expression of Nrf2 and HO-1 was significantly lower in the model group than in the blank group, and the expression was significantly higher in the medium-dose ESP group than in the model group. In conclusion, ESP protected mice against the scopolamine-induced learning and memory impairment by regulating the Keap1/Nrf2/HO-1 signaling pathway.
