Objective:To analyze the influencing factors related to the prognosis of delayed replantation of avulsed permanent teeth.Methods:A retrospective study was conducted on the clinical data of 35 patients with 38 affected teeth underwent delayed replantation of permanent teeth.According to the prognosis after 12 to 108 months of follow-up,the replantation results of the cases were divided into-success,survival and failure groups.Survival curves were plotted using Kaplan-Meier method,Log-Rank test was used for univariate analysis,and Cox proportional risk regression models were used for multivariate analysis to assess the effects of gender,age,degree of tooth development,mode of tooth preservation and mode of endodontic treatment on the survival rate of replanted teeth.Results:Of the 38 replanted teeth,3 were successful,28 remained and 10 failed.The 9-year cumulative survival rate of the replanted teeth was 34.7％.The results showed that there were no statistically significant differences in the survival rate of the replanted teeth in the groups with different sex,age,degree of tooth development and the mode of preservation of avulsed teeth(P＞0.05).There were statistically significant differences in the cumulative survival rate of the replanted teeth among the groups with different endodontic treatment(P＜0.01),which showed that the cumulative survival rate in the root canal filling group＞continuous root canal sealing group＞pulp preserva-tion treatment group.Conclusion:For the delayed replantation of avulsed premanent teeth,survival prognosis of the teeth treated with pulp preservation is poor,early pulp extraction and root canal filling are recommended.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Due to factors such as an aging population, the Hospital Authority(HA) of Hong Kong is facing a contradiction between limited health resource supply and continuously increasing demand. In order to effectively address challenges, the HA prompted three measures to bridging the demand-supply gap. The HA relied on its management system advantages to continuously increase its capital construction to enhance the service capacity of public health institutions; transformed service delivery mode so as to improve the experience, quality, and efficiency of service delivery; established cooperation with private service providers and communities to shunt population health demand. The practices of HA can provide reference for public hospitals and their sponsors in other regions of China.

ObjectiveTo investigate the effects of thyme herbal tea （BLX） on the proliferation of human coronavirus OC43 （HCoV-OC43） in vitro and in vivo. MethodThe chemical composition of BLX was analyzed by UPLC-MS. The cytotoxicity of BLX in HRT-18 cells and the effect of BLX treatment on the proliferation of HCoV-OC43 in cells were analyzed. Copies of viral gene were detected by real-time PCR. The effect of BLX treatment on the life cycle of HCoV-OC43 was detected by time-of-addition assay. The maximum tolerated dose of BLX and the influences of BLX on the body weight and survival time of suckling mice infected with HCoV-OC43 were determined. The expression of viral protein in the brain and lung tissue was analyzed by immunohistochemistry. ResultThere were 11 chemical components identified in BLX by UPLC-MS. BLX showed the 50% cytotoxic concentration （CC₅₀） of （13 859.56±319） mg·L^-1， the median inhibitory concentration （IC₅₀） of （1 439.09±200） mg·L^-1， and the selection index of 8.26-11.44 for HCoV-OC43 in HRT-18 cells. Compared with the cells infected with HCoV-OC43， BLX at the concentrations of 1 500， 1 000， 500 mg·L^-1 inhibited the proliferation of this virus （P<0.05， P<0.01）. BLX exhibited antiviral effect in the early stage of virus infection， and the inhibition role in the attachment stage was more significant than that in the entry stage （P<0.05）. In the suckling mice infected with HCoV-OC43， BLX at 1200 and 600 mg·kg^-1·d^-1 alleviated the symptoms， prolonged the survival period， reduced the death rate， and down-regulated the mRNA level of nucleocapsid protein in the mice. Moreover， BLX at 1 200 mg·kg^-1·d^-1 down-regulated the expression of nucleocapsid protein in the brain （P<0.01） and the lung （P<0.01）. ConclusionBLX contained multiple antiviral ingredients. It inhibited the proliferation of HCoV-OC43 both in vitro and in vivo by interference with viral attachment. This study provides theoretical reference for the treatment of acute respiratory tract infection with HCoV-OC43 and for further development and application of BLX.

OBJECTIVE To establish a clinical pharmaceutical pathway of anti-infective therapy for high-risk populations of antibiotic-associated encephalopathy （AAE）， and analyze its application effects. METHODS Clinical pharmacists developed the “AAE High-Risk Population Screening Form” and “Antibiotic AAE Risk Comparison Form” based on literature and expert opinions， and established the “Clinical Pharmaceutical Pathway of Anti-infective Treatment for AAE High-Risk Population” in our hospital. A prospective， non-randomized controlled study was conducted from May 2023 to April 2024， including 50 cases in the observation group and 50 cases in the control group among patients with pulmonary infections admitted to the Dept. of Internal Medicine in our hospital. The observation group was involved in the development of an anti-infective treatment following the clinical pharmaceutical pathway by clinical pharmacists， while the control group received routine anti-infective treatment by clinical physicians. The occurrence of AAE， the rational antibiotic drug use， and the effectiveness of initial anti-infective treatment in the two groups were observed， and the intervention measures and outcomes of AAE cases were summarized. RESULTS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population was preliminarily established in our hospital. The analysis of the application effects showed that there was 1 case of AAE in the observation group and 8 cases in the control group， with a significantly lower incidence of AAE in the observation group than in the control group； the rational antibiotic drug use and the effectiveness of initial anti-infective treatment in the observation group were both significantly superior to those in the control group （P＜0.05）. Drug withdrawal and dressing change were the preferred effective intervention measures for AAE， and encephalopathy treatment drugs could be used as auxiliary measures for symptom relief. Timely and effective intervention was conducive to rapid symptom relief， with a total improvement rate of AAE of 88.89%. CONCLUSIONS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population can effectively prevent the occurrence of AAE as well as contribute to promoting rational drug use and the effectiveness of initial anti-infection plans and strengthening treatment outcomes.

Objective:To investigate the role of RNA m6A methylation in mediating cerebellar dysplasia through analyzing the phenotypes of the mouse cerebella and the expression of several key m6A regulators upon hypobaric hypoxia treatment.Methods:Five-day old C57/BL6 mice were exposed to hypobaric hypoxia for 9 days. The status of mouse cerebellar development was analyzed by comparing the body weights, brain weights and histological features. Immunostaining of cell-type-specific markers was performed to analyze the cerebellar morphology. Real-time PCR, Western blot and immunohistochemical staining were performed to detect the expression of key m6A regulators in the mouse cerebella.Results:Compared with the control, the body weights, brain weights and cerebellar volumes of hypobaric hypoxic mice were significantly reduced ( P<0.01). The expression of specific markers in different cells, including NeuN (mature neuron), Calbindin-D28K (Purkinje cell) and GFAP (astrocyte), was decreased in hypobaric hypoxic mouse cerebella ( P<0.01), accompanied with disorganized cellular structure. The expression of methyltransferase METTL3 was significantly down-regulated in the cerebella of hypobaric hypoxic mice ( P<0.05). Conclusions:Hypobaric hypoxia stimulation causes mouse cerebellar dysplasia, with structural abnormalities in mature granular neurons, Purkinje cells and astrocytes. Expression of METTL3 is decreased in hypobaric hypoxic mice cerebellum compared with that of normobaric normoxic mice, suggesting that its mediated RNA m6A methylation may play an important role in hypobaric hypoxia-induced mouse cerebellar dysplasia.

Hormone receptor-positive/HER-2-negative(HR+/HER2-)breast cancer exhibits low sensitivity to neoadjuvant chemotherapy(NCT);with minimal benefits observed from NCT.Neoadjuvant endocrine therapy(NET)achieves a clinical response comparable to that of NCT,but with lower toxicity.In addition,CDK4/6 inhibitors have changed the treatment landscape of HR+/HER2-breast cancer,raising new clinical challenges in the selection of the most effective endocrine therapies.In clinical practice,adaptive research designs should be adop-ted based on tumor biology,therapeutic efficacy,and tumor burden.In addition,optimizing treatment strategies and performing precise treatment is important.In this review,we discuss the application value of NET,efficacy evaluating and predicting methods,and potential NET-based combination therapies to provide reference information regarding the treatment of HR+/HER2-breast cancer for clinicians.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To investigate the value of the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS), real-time ultrasound elastography (RTE), and contrast-enhanced ultrasound (CEUS), individually and in combination, in the diagnosis of TBSRTC Ⅲ-Ⅴ thyroid nodules.Methods:A retrospective analysis was performed on 106 patients with TBSRTC Ⅲ-Ⅴ thyroid nodules who were pathologically diagnosed by fine needle aspiration cytology at Bao Ji People's Hospital between February 2022 and December 2023. All patients were assessed using ACR TI-RADS grading, RTE, and CEUS, with postoperative pathological diagnosis serving as the gold standard. The diagnostic effectiveness of ACR TI-RADS, RTE, and CEUS, individually and in combination, for TBSRTC Ⅲ-Ⅴ thyroid nodules was analyzed using the receiver operating characteristic (ROC) curve.Results:There were statistically significant differences in nodule size, blood supply, and proportion of TBSRTC Ⅲ-Ⅴ nodule between the two groups ( χ2 = 4.67, 42.56, 26.09, all P < 0.05), while there was no statistical significance in other general data (all P > 0.05). Of the 106 patients with TBSRTC Ⅲ-Ⅴ nodules, 69 patients were diagnosed with malignant nodules and 37 with benign nodules. The area under the curve (95% CI) of ACR-TIRADS, RTE, and CEUS in identifying malignant nodules were 0.860 [95% CI (0.779-0.920)], 0.712 [95% CI (0.616-0.796)], and 0.788 [95% CI (0.698-0.862)], respectively, with sensitivities of 85.51%, 66.67%, and 73.91%, respectively and specificities of 86.49%, 75.68%, and 83.78%, respectively. The Youden indices were 0.719, 0.423, and 0.577, respectively. Among the three diagnostic methods, ACR TI-RADS had the highest diagnostic efficiency, while RTE had the lowest. Pairwise comparisons in ROC analysis revealed statistically significant differences between ACR TI-RADS and RTE, ACR TI-RADS and CEUS, as well as RTE and CEUS ( Z = 4.22, 3.02, 2.78, all P < 0.05). The ACR TI-RADS + RTE + CEUS combination had the highest sensitivity, specificity, Youden index, and AUC (95% CI) values: 94.20%, 89.19%, 0.834, and 0.917 (95% CI: 0.847-0.962). The RTE + CEUS combination had the lowest values: 76.81%, 78.38%, 0.552, and 0.776 (95% CI: 0.685-0.851). The pairwise comparison results in the ROC curve revealed that significant differences were observed between ACR TI-RADS + RTE and RTE + CEUS, ACR TI-RADS + RTE and ACR TI-RADS + RTE + CEUS, ACR TI-RADS + CEUS and ACR TI-RADS + RTE + CEUS, RTE + CEUS and ACR TI-RADS + RTE + CEUS, and ACR TI-RADS + CEUS and RTE + CEUS ( Z = 3.13, 2.40, 2.16, 4.07, 3.32, all P < 0.05). However, there was no significant difference between ACR TI-RADS + RTE and ACR TI-RADS + CEUS in ROC analysis ( Z = 0.06, P > 0.05). Conclusion:The combined utilization of ACR TI-RADS, RTE, and CEUS offers enhanced information on thyroid nodules, encompassing malignant risk stratification, nodular elasticity, and contrast agent perfusion, thereby aiding in improving the diagnostic precision of TBSRTC Ⅲ-Ⅴ malignant nodules.
