With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective:To investigate the early clinical characteristics of elderly patients with severe burns and the risk factors on prognosis.Methods:This study was a retrospective case series study. Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon gene (STING) signal pathway is a classical pathway of STING activation, and in recent years, its role in stimulating innate immunity has gradually attracted wide attention. Besides, cGAS can recognize and combine endogenous or exogenous DNA, then catalyze ATP and GTP to synthesize cyclic guanosine monophosphate-adenosine monophosphate (cGAMP), subsequently activate STING signal to promote type I interferon and inflammatory factors, finally induce natural and adaptive immunity. Existing studies have indicated that cGAS-STING signal pathway plays an important role in infections, inflammations and tumors, especially in high-grade gliomas with poor clinical treatment efficacy. Here, we briefly summarize the cGAS-STING signal pathway and its mechanism in brain tumors to provide new ideas for exploring therapeutic targets and drugs for brain tumors.

As an essential trace element in living organisms, copper is actively involved in normal physiological processes in various systems and is maintained at low level to achieve copper homeostasis. Copper homeostasis, once being disrupted, would induce cell death, and this new form of cell death is known as copper death. In recent years, copper death has been increasingly recognized as an important factor mediating the onset and progression of central nervous system (CNS) diseases. Therefore, we review the pathogenic mechanism of copper death in CNS diseases, as well as its therapeutic strategies so as to deepen the understanding of researchers.

Objective:To observe the effects of linalool on central and alleviating peripheral nervous system through transient receptor potential vanilloid 1 (TRPV1) pathway and its role in alleviating visceral hypersensitivity in irritable bowel syndrome (IBS).Methods:Thirty-six female newborn Sprague-Dawley (SD) rat pups in specific pothogen free was selected, among which 30 rats were used for behavioral experiments and 6 rats for electrophysiological experiment. In behavioral experiments, 30 newborn SD rats were randomly divided into normal control group (0.2 mL 0.9% sodium chloride solution was injected into the colorectal), neonatal colonic inflammation (NCI) group (0.2 mL 0.5% acetic acid was injected into the colorectal), linalool 20, 50 and 100 mg/kg groups (after NCI model successfully established, the rat were gavaged with linalool 20, 50 or 100 mg/kg at 5 weeks old). At 6 weeks old, abdominal withdrawal reflex (AWR) and pressure value of pain threshold (inflation pressure value at AWR score of 3) was observed by colorectal distention test. One hour after behavioral experiments, the expression of TRPV1 at protein level in colonic mucosa and spinal cord of each group was detected by Western blotting and immunohistochemistry. In electrophysiological experiment, female SD rats aged 6 to 7 weeks were selected to make in vitro transverse sections of the spinal cord. Five to eight neurons were randomly selected from each rat for whole-cell patch-clamp recording. The effects of linalool, tetrodotoxin and anti capsaicinand on the spontaneous excitatory postsynaptic current (sEPSC) of substantiagelatinosa neurons was recorded. Independent sample t test and paired t test were used for statistical analysis. Results:The AWR score of rats in NCI group was higher than those in normal control group, linalool 20 mg/kg group, linalool 50 mg/kg group and linalool 100 mg/kg group at 40 mmHg (1 mmHg=0.133 kPa) pressure (2.5±0.2 vs. 1.0±0.3, 1.5±0.3, 1.5±0.2, and 1.5±0.2, respectively), at 60 mmHg pressure the AWR score was higher than those in normal control group, linalool 50 mg/kg group and linalool 100 mg/kg group (3.8±0.2 vs. 2.3±0.4, 2.3±0.5, and 2.0±0.3, respectively), and the differences were statistically significant ( t=4.39, 2.45, 3.16, 3.16, 3.31, 2.88 and 5.97; P=0.001, 0.034, 0.010, 0.010, 0.008, 0.028, and<0.001). The pain threshold of rats in NCI group was lower than those of normal control group, linalool 20 mg/kg group, linalool 50 mg/kg group and linalool 100 mg/kg group ((35.8±2.0) mmHg vs. (55.8±1.5), (49.2±2.4), (53.3±2.1), and (55.0±1.8) mmHg, respectively), and the differences were statistically significant ( t=-7.91, -4.28, -6.01, and -7.06; P<0.001, =0.002, <0.001, and <0.001). The results of Western blotting showed that the relative expression of TRPV1 at protein level in colorectal tissues of rats in NCI group was higher than those of normal control group, linalool 20 mg/kg group, linalool 50 mg/kg group and linalool 100 mg/kg group (0.86±0.03 vs. 0.32±0.03, 0.68±0.01, 0.45±0.03, and 0.56±0.02, respectively), and the relative expression of TRPV1 at protein level in spinal dorsal horn was higher than those of normal control group, linalool 20 mg/kg group, linalool 50 mg/kg group and linalool 100 mg/kg group (0.91±0.02 vs. 0.34±0.03, 0.72±0.03, 0.51±0.06, and 0.63±0.05), and the differences were statistically significant ( t=12.44, 5.14, 9.68, 7.69, 19.14, 5.13, 6.72, and 5.60; P<0.001, <0.001, <0.001, <0.001, <0.001, <0.001, =0.001, and <0.001). There were no statistically significant differences in the frequency and the outward current of sEPSC in neurons of same glial region among rats with 2 mmol/L linalool gavaged for 4 minutes, 0.5 μmol/L tetrodotoxin and 2 mmol/L linalool gavaged for 4 minutes ( n=5, (23.84±4.81) Hz vs. (20.54±5.71) Hz, (7.60±0.35) pA vs. (7.62±0.75) pA, both P>0.05). The frequency of sEPSC administered with 2 mmol/L linalool gavaged for 4 minutes was higher than that of neurons in the same glial area administered with 10 μmol/L capsazepine and 2 mmol/L linalool gavaged for 4 minutes ( n=5, (20.17±2.55) Hz vs.(14.09±2.98) Hz), and the difference was statistically significant ( t=3.58, P=0.021); however there was no statistically significant difference in the outward current ((7.42±0.78) pA vs. (7.03±1.32) pA, P>0.05). Conclusion:Linalool can relieve visceral hypersensitivity in IBS partially through TRPV1 pathway, which may be related to the hyperpolarization of the membrane potential of neurons in glial region.

Objective:To investigate the efficacy of free superficial circumflex iliac artery perforator flap (SCIAPF) in reconstruction of the donor site of hallux nail flap.Methods:From December 2015 to December 2022, Section Ⅲ of Department of Hand Surgery of Hangzhou Plastic Surgery Hospital conducted thumb reconstruction surgery with free hallax nail flaps for 12 patients with traumatic defects of thumbs. Six patients had degloving injuries of thumb with intact bone scaffold and extensor-flexor tendon. Among the other 6 patients with thumb defects, 3 had grade I defect, 2 had grade II defect and 1 had grade Ⅲ defect, according to Gu Yudong's classification. Free SCIAPFs were used to reconstruct the donor sites of hallux nail flaps. Sizes of the flaps were 3.0 cm× 6.5 cm-9.0 cm ×7.0 cm. All donor sites in the abdomen were directly sutured. After surgery, functional evaluations of the reconstructed thumb were conducted through follow-ups at outpatient clinics and(or) by WeChat interviews, according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, and the functional evaluation of donor feet was conducted according to the Maryland foot function evaluation standard.Results:Successful survival of the 9 cases of flap in the donor site of hallux nail flap. One patient had venous occlusion of flap and survived after timely surgical exploration. One flap had partial necrosis at the tip of flap, and the wound was eliminated with local transfer of a flap. One patient had necrosis over most of the flap with the base of the flap survived, and the wound was repaired by a stage-II skin grafting. The donor sites at groin healed in stage-I in all of 11 patients with a linear scar. One patient who had haematoma at the donor site was cured by removal of the haematoma and a re-suture. All the patients received a 3 to 24 months of postoperative follow-up. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 10 patients were in excellent and 2 in good. All of the great toes remained with original length and recovered normal flexion and extension. No patient suffered pain while walking and running. According to the Maryland foot function evaluation standard, 10 patients were in excellent and 2 in good. All SCIAPFs were satisfactory in colour and texture. Five patients had bloated flaps and underwent Hacks in the stage-Ⅱ.Conclusion:Application of a free SCIAPF in reconstruction of the donor site for hallux nail flap can effectively preserve the appearance and function of the donor site. Meanwhile, the scar in the donor site of groin is concealed with little damage, therefore the groin meets the requirements as a donor site of a flap.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To evaluate the clinical significance of neoadjuvant immunotherapy combined with chemotherapy in the treatment of larynx preservation in locally advanced hypopharyngeal squamous cell carcinoma. Methods:Patients with locally advanced HPSCC（cT3-T4aN0-N3M0） were eligible. All received 2 cycles of pembrolizumab combined with docetaxel and platinum neoadjuvant induction therapy. After two cycles, the efficacy was evaluated, followed by radical chemoradiotherapy or surgery and adjuvant chemoradiotherapy according to the efficacy. The primary endpoints were objective response rate（ORR） ，larynx-preservation（LP） rate at 3 months post-treatment and the adverse reactions during neoadjuvant therapy. Results:From December 2021 to December 2022, 10 patients with locally advanced HPSCC（cT3-T4aN0-N3M0） were enrolled. After 2 cycles of the neoadjuvant therapy, 2 patients achieved complete response（CR）, 7 patients achieved partial response（PR）, 1 patient was stable disease（SD）, objective response rate（ORR） was 90%, and disease control rate（DCR） was 100%. 5 patients received radical chemoradiotherapy, 5 patients received surgery and adjuvant chemoradiotherapy, four of them received partial laryngectomy and partial hypopharyngeal resection surgery, and one of them received total laryngectomy and partial hypopharyngeal resection surgery. All patients were able to withstand adverse reactions of neoadjuvant therapy and successfully completed the whole treatment of HPSCC without grade 3-4 treatment-related adverse reactions. There was no recurrence or metastasis during 3-18 months of follow-up. 1 patient died of severe pneumonia 3 months after the completion of radical chemoradiotherapy. At 3 months after treatment, the larynx-preservation rate was 80%. Conclusion:Neoadjuvant immunotherapy combined with chemotherapy has good short-term efficacy and the adverse reactions were tolerable. It can improve the larynx-preservation rate of patients with locally advanced HPSCC, thus improving the prognosis and quality of life of patients.
