Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

This research study focuses on addressing the limitations of current neuropathic pain (NP) treatments by developing a novel dual-target modulator, E0199, targeting both Na_V1.7, Na_V1.8, and Na_V1.9 and K_V7 channels, a crucial regulator in controlling NP symptoms. The objective of the study was to synthesize a compound capable of modulating these channels to alleviate NP. Through an experimental design involving both in vitro and in vivo methods, E0199 was tested for its efficacy on ion channels and its therapeutic potential in a chronic constriction injury (CCI) mouse model. The results demonstrated that E0199 significantly inhibited Na_V1.7, Na_V1.8, and Na_V1.9 channels with a particularly low half maximal inhibitory concentration (IC₅₀) for Na_V1.9 by promoting sodium channel inactivation, and also effectively increased K_V7.2/7.3, K_V7.2, and K_V7.5 channels, excluding K_V7.1 by promoting potassium channel activation. This dual action significantly reduced the excitability of dorsal root ganglion neurons and alleviated pain hypersensitivity in mice at low doses, indicating a potent analgesic effect without affecting heart and skeletal muscle ion channels critically. The safety of E0199 was supported by neurobehavioral evaluations. Conclusively, E0199 represents a ground-breaking approach in NP treatment, showcasing the potential of dual-target small-molecule compounds in providing a more effective and safe therapeutic option for NP. This study introduces a promising direction for the future development of NP therapeutics.

Increasing evidence showed that histone deacetylase 6 (HDAC6) dysfunction is directly associated with the onset and progression of various diseases, especially cancers, making the development of HDAC6-targeted anti-tumor agents a research hotspot. In this study, artificial intelligence (AI) technology and molecular simulation strategies were fully integrated to construct an efficient and precise drug screening pipeline, which combined Voting strategy based on compound-protein interaction (CPI) prediction models, cascade molecular docking, and molecular dynamic (MD) simulations. The biological potential of the screened compounds was further evaluated through enzymatic and cellular activity assays. Among the identified compounds, Cmpd.18 exhibited more potent HDAC6 enzyme inhibitory activity (IC₅₀ = 5.41 nM) than that of tubastatin A (TubA) (IC₅₀ = 15.11 nM), along with a favorable subtype selectivity profile (selectivity index ≈ 117.23 for HDAC1), which was further verified by the Western blot analysis. Additionally, Cmpd.18 induced G2/M phase arrest and promoted apoptosis in HCT-116 cells, exerting desirable antiproliferative activity (IC₅₀ = 2.59 μM). Furthermore, based on long-term MD simulation trajectory, the key residues facilitating Cmpd.18's binding were identified by decomposition free energy analysis, thereby elucidating its binding mechanism. Moreover, the representative conformation analysis also indicated that Cmpd.18 could stably bind to the active pocket in an effective conformation, thus demonstrating the potential for in-depth research of the 2-(2-phenoxyethyl)pyridazin-3(2H)-one scaffold.

The emerging and re-emerging arthropod-borne infectious diseases pose a serious threat to global public health security. Field and laboratory studies of arthropods of medical importance are essential and critical for the prevention and control of arthropod-borne infectious diseases. Various institutions or universities in China have been conducting research in the field or laboratory study of arthropods of medical importance, but up to 2023, it is still lacking detailed biosafety guidelines or recommendations that can guide the related work for arthropods of medical importance. In order to proactively address potential biosafety issues in the field or laboratory activities related to arthropods of medical importance, improve the standardization of arthropod biosafety classification, operations, and protection, and ensure the safety of practitioners, an expert consensus on the biosafety recommendation of arthropods of medical importance in field and laboratory has been developed, aiming to guide the future work of arthropods and ensure the national biosafety and biosecurity of China.

Objective:To investigate the effects of endocrine drugs on tumor markers and endometrium after breast cancer surgery.Methods:Eighty-eight patients with endocrine therapy for breast cancer admitted to the Heping Hospital Affiliated to Changzhi Medical College from November 2018 to March 2022 were selected, 44 patients taken orally tamoxifen citrate tablets were enrolled in the study group, 44 patients taken orally anastrozole tablets were enrolled in the control group, the patients in the two groups were treated for 12 months. The tumor markers, endometrial thickness were compared between the two groups before treatment and 12 months after treatment. The drug safety was compared too.Results:After treatment, the serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125) and glycochain antigen 15-3 (CA15-3) in both groups were decreased, and the level of tumor markers in the study group were lower than those in the control group: (3.01 ± 0.23) μg/L vs.(3.89 ± 1.15) μg/L, (4.22 ± 1.21) kU/L vs. (7.38 ± 2.19) kU/L, (16.76 ± 2.19) kU/L vs. (19.87 ± 2.21) kU/L, there were statistical differences ( P<0.05).

Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.

We report the intrauterine treatment of a case of fetal persistent supraventricular tachycardia complicated by heart failure. The ultrasound findings at 32 +1 weeks of gestation showed fetal tachycardia of 242 beats/min, fetal generalized edema, ascites, and visible pulsation spectrum in the intra-abdominal segment of the umbilical vein. Fetal cardiac arrhythmia persisted after maternal oral digoxin for 46 hours. In view of the continuous deterioration of the fetal condition with the persistent umbilical vein pulsation spectrum and worsening edema, fetal intramuscular injection of cedilanid under ultrasound guidance was performed, resulting in successful cardioversion. The pregnant woman gave birth to a baby girl by cesarean section due to premature rupture of membranes and oligohydramnios at 34 +6 weeks of gestation, with normal functions of heart and other organs. During a follow-up to 8 months, no obvious abnormalities were found.

Oral cancer is one of the most common cancers that occur in the head and neck and can seriously affect the life span and living standard of oral cancer patients. Candida albicans （C. albicans） is the most common opportunistic pathogenic fungus in the oral cavity, shows pathogenicity and easily causes Candida infection when the host′s immune function is low. Recent studies have shown that C. albicans infection is closely related to oral cancer. This paper reviews the epidemiology of C. albicans infection in oral cancer patients, the influence of C. albicans infection on the occurrence and development of oral cancer and research on its mechanism. Existing studies have shown an increased risk of C. albicans infection in oral cancer patients, while C. albicans infection may promote the occurrence and development of oral cancer through mechanisms such as damaging the oral epithelium; producing carcinogens, including nitrosamine and acetaldehyde; and inducing a chronic inflammatory response and T helper cell 17 immune response. However, these mechanisms are still relatively superficial and lack sufficient direct evidence. In the future, additional in-depth studies are still needed to further clarify the cancer-promoting mechanisms of C. albicans and provide new ideas for the prevention and treatment of oral cancer.

OBJECTIVE：To study the pr otective effect of schisandrin A （SA）on CCl 4-induced liver fibrosis model mice and its mechanism. METHODS ：Mice were randomly divided into blank control group ，model group ，silymarin group （positive control，100 mg/kg），SA low-dose and high-dose groups （20，40 mg/kg），with 10 mice in each group. Except for blank control group，other groups were given CCl 4 subcutaneously to induce liver fibrosis model. After successful modeling ，administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 6 weeks；blank control group and model group were given constant volume of 0.5％sodium carboxymethyl cellulose solution intragastrically by the same way. HE staining was used to observe the pathological changes of liver tissue in mice. UV spectrophotometry and ELISA assay were adopted to detect the serum levels of liver injury indexes （ALT and AST ）and the contents of inflammatory factors （TNF-α，IL-1β，IL-6）. Western blotting assay was used to detect the expression of NOD like receptor protein 3（NLRP3）/NF-κB and TGF-β/Smad signaling pathway protein. RESULTS ：Compared with blank control group ，obvious pathological changes of liver fibrosis were observed in model group. The serum levels of liver injury indexes and contents of inflammatory factors were significantly increased （P＜0.01）. The expression of NLRP 3，apoptosis associated spot-like protein ，Caspase-1 and IL- 1β，TGF-β1 and ratios ofp-NF-κB p65/NF-κB p65，p-IκBα/IκBα，p-Samd3/Smad3 were increased significantly （P＜0.01）. Compared with model group ，SA could significantly relieve hepatic fibrosis in mice ，reduce serum levels of liver injury indexes and contents of inflammatory factors ，as well as the expression of NLRP 3/NF-κB and TGF-β/Smad signaling pathway protein and phosphorylation level（P＜0.01）. CONCLUSIONS ： SA can effectively relieve liver injury and inflammation of CCl 4-induced hepatic fibrosis model mice ，which may be through the regulation of NLRP 3/NF-κB and TGF-β/Smad3 signaling pathways ，thus inhibiting the process of liver fibrosis.
