Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

AIM:To investigate the effect of orthokeratology on myopia progression in contralateral eyes of adolescents with monocular myopic anisometropia.METHODS:Prospective clinical control study. From January 2021 to August 2021 at Nanning Aier Eye Hospital, 35 patients(70 eyes)diagnosed with monocular myopia and opting for single vision frame glasses correction were recruited as the SV group, and 35 patients(70 eyes)opting for orthokeratology correction were recruited as the OK group, with 1 year of follow-up. Both eyes in the SV group wore single vision lenses, while the myopic eye in the OK group wore an orthokeratology lens, with no intervention in the contralateral eye. After wearing glasses for 6 and 12 mo, the axial lengths of the myopic and contralateral eyes in both groups were measured again, and the data were statistically analyzed.RESULTS:After wearing lenses for 6 and 12 mo, the axial length of the myopic eye of patients in the SV group increased by 0.18±0.07 and 0.35±0.12 mm, respectively, and that of the contralateral eye increased by 0.10±0.05 and 0.23±0.10 mm, respectively. In the OK group, the axial length of the myopic eye of patients, increased by 0.09±0.05 and 0.16±0.09 mm, respectively, and that of the contralateral eye increased by 0.19±0.08 and 0.38±0.13 mm, respectively. The axial length growth of the myopic eye in the SV group was higher than that in the OK group at different time points(t=0.367, P<0.001; t=0.688, P<0.001), whereas the axial length growth of the contralateral eye was lower than that in the OK group(t=0.074, P<0.001; t=0.170, P<0.001). After wearing lenses for 6 and 12 mo, the interocular axial length difference values increased by 0.08±0.05 and 0.12±0.08 mm in the SV group, but decreased by 0.10±0.07 and 0.21±0.12 mm in the OK group, respectively. A statistically significant inter-group difference was observed in the change of interocular axial length discrepancy after wearing lenses for 6 and 12 mo(t=0.111, P<0.001; t=0.084, P<0.001).CONCLUSION:Compared with single vision frame glasses, wearing an orthokeratology lens in the myopic eye can effectively help inhibit the growth of axial length and reduce the degree of anisometropia in adolescents with monocular myopic anisometropia, but there is a potential risk of promoting the growth of axial length in the contralateral eye.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To compare the medical costs of using standard fortified donor human milk (DHM) or preterm formula (PF) to supply very low birth weight [VLBW, defined as birth weight (BW) ≥1 000 g but <1 500 g] and extremely low birth weight (ELBW, defined as BW <1 000 g) premature infants with insufficient maternal breast milk.Methods:VLBW and ELBW preterm infants hospitalized in Peking Union Medical College Hospital from September 2017 to October 2020 were retrospectively enrolled and assigned into DHM group and PF group based on complementary feeding methods. The cost of parenteral nutrition (PN), cost of antibiotics, and total medical expenses during hospitalization were compared between the two groups.Results:A total of 89 infants were enrolled in this study, out of whom 50 was in the DHM group and 39 the PF group. The gestational age in DHM group and PF group were both (29±2) weeks. The BW of DHM group was 1 170 (919, 1 380)?g and that of PF group was 1 170 (1 010, 1 360) g. There were no significant differences in gestational age, BW, maternal age at delivery, delivery mode, gender ratio, proportion of small-for-gestational-age infants and length of hospital stay between the two groups (all P>0.05). The cost of parenteral nutrition in DHM group was significantly lower than that in PF group [3 500 (1 922, 5 704) Chinese yuan vs 7 995 (5 579, 10 788) Chinese Yuan, P<0.01]. The cost of antibiotics in DHM group was significantly lower than that in PF group [6 529 (2 265, 10 860) Chinese Yuan vs 13 676 (10 480, 18 506) Chinese Yuan, P<0.01]. The difference in total medical expense during hospitalization showed no statistical significance between two groups ( P>0.05). Amorg VLBW preterm infants, the cost of PN, cost of antibiotics, total cost of hospitalization, and daily cost of hospitalization in HDM group was significantly lower than that in PF group (all P<0.05). In ELBW preterm infants, the cost of PN and the cost of antibiotics in HDM group were significantly lower than that in PF group (both P<0.05), but the total cost of hospitalization and the daily cost of hospitalization between two groups showed no significant difference (all P>0.05). Conclusions:When mother's own milk is insufficient, using donor human milk reduces the costs of PN and antibiotics in VLBW and ELBW preterm infants compared with using PF. In VLBW preterm infants, using DHM can also reduce the total and daily cost of hospitalization.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

OBJECTIVE: Tumor-derived exosomes (TDEs) play crucial roles in intercellular communication. Hypoxia in the tumor microenvironment enhances secretion of TDEs and accelerates tumor metastasis. Jiedu recipe (JR), a traditional Chinese medicinal formula, has demonstrated efficacy in preventing the metastasis of hepatocellular carcinoma (HCC). However, the underlying mechanism remains largely unknown. METHODS: Animal experiments were performed to investigate the metastasis-preventing effects of JR. Bioinformatics analysis and in vitro assays were conducted to explore the potential targets and active components of JR. TDEs were assessed using nanoparticle tracking analysis (NTA) and Western blotting (WB). Exosomes derived from normoxic or hypoxic HCC cells (H-TDEs) were collected to establish premetastatic mouse models. JR was intragastrically administered to evaluate its metastasis-preventive effects. WB and lysosomal staining were performed to investigate the effects of JR on lysosomal function and autophagy. Bioinformatics analysis, WB, NTA, and immunofluorescence staining were used to identify the active components and potential targets of JR. RESULTS: JR effectively inhibited subcutaneous-tumor-promoted lung premetastatic niche development and tumor metastasis. It inhibited the release of exosomes from tumor cells under hypoxic condition. JR treatment promoted both lysosomal acidification and suppressed secretory autophagy, which were dysregulated in hypoxic tumor cells. Quercetin was identified as the active component in JR, and the epidermal growth factor receptor (EGFR) was identified as a potential target. Quercetin inhibited EGFR phosphorylation and promoted the nuclear translocation of transcription factor EB (TFEB). Hypoxia-impaired lysosomal function was restored, and secretory autophagy was alleviated by quercetin treatment. CONCLUSION JR suppressed HCC metastasis by inhibiting hypoxia-stimulated exosome release, restoring lysosomal function, and suppressing secretory autophagy. Quercetin acted as a key component of JR and regulated TDE release through EGFR-TFEB signaling. Our study provides a potential strategy for retarding tumor metastasis by targeting H-TDE secretion.

Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues.Magnesium has been proved to promote bone healing under normal conditions.Here,we elucidate the mechanism by which Mg2+ promotes angiogenesis and osseointegration in diabetic status.We generated a diabetic mice model and demonstrated the alveolar bone healing was compromised,with significantly decreased angiogenesis.We then developed Mg-coating implants with hydrothermal synthesis.These implants successfully improved the vascularization and osseointegration in diabetic status.Mechanically,Mg2+ promoted the degradation of Kelch-like ECH-associated protein 1(Keap1)and the nucleation of nuclear factor erythroid 2-related factor 2(Nrf2)by up-regulating the expression of sestrin 2(SESN2)in endothelial cells,thus reducing the elevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia.Altogether,our data suggested that Mg2+ promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondrial metabolism.
