As orthodontic treatment improves malocclusion and enhances oral health quality,the number of orthodontic patients is steadily increasing.However,a lack of understanding of periodontal inflammation and the health of periodontal supporting tissues during orthodontic treatment can lead to alveolar bone destruction and resorption.This,in turn,results in periodontal hard tissue-related com-plications such as bone fenestration,bone dehiscence,abnormal interradicular distance,and tooth mobility or loss.Currently,these complications present a significant challenge in orthodontic practice.This paper provides a comprehensive overview of common perio-dontal hard tissue-related complications during orthodontic treatment,along with clinical prevention and management strategies.A typi-cal case of multidisciplinary periodontal treatment is also presented,addressing alveolar bone resorption and tooth mobility in the upper anterior teeth caused by improper orthodontic treatment.This report aims to offer valuable reference for clinicians.

Objective To analyze the correlation between tongue image features and the risk levels of disease in patients with idiopathic membranous nephropathy(IMN).Methods Based on IMN clinical research electronic data acquisition system,a cross-sectional study method was used to analyze the clinical diagnosis and treatment data of 135 IMN patients from Guangdong Provincial Hospital of Chinese Medicine.The patients were grouped according to the risk levels of disease,and then the correlation between the risk levels of disease and tongue image features was analyzed.During the description of tongue image features,TB is for tongue body,TC is for tongue coating,L is for luminance,a is for red-green axis,G is for the value of green,B is for the value of blue,and AUT is for the value of autocorrelation.Results The comparison of tongue image feature indicators of patients with different risk levels of IMN showed that:(1)the higher the level of disease risk of IMN patients,the greater the values of TB-L,TB-G and TB-B(P<0.05 or P<0.01).The values of tongue image indicator TB-a and TC-a of the patients with different risk levels of IMN were shown in decreasing sequence:low-risk group>high-risk group>middle-risk group>extremely-high-risk group(P<0.05).(2)Linear regression analysis showed that TB-L,TB-G,and TB-B were significantly increased in the high-risk group compared with those in the middle-and low-risk groups(P<0.05 or P<0.01),whereas there were no significant differences between the middle-risk group and low-risk group(P>0.05).(3)The results of correlation analysis showed that there was a positive correlation among most of the tongue image feature indicators(including TB-L,TB-G,TB-B,TB-AUT,TC-L,TC-G,and TC-B,etc.)and the risk level of disease,while TB-a was negatively correlated with the risk level of disease,and the differences were all statistically significant(P<0.05 or P<0.01).(4)All patients were treated with Chinese medicine and/or Chinese patent medicine,and 46.7%of patients were given hormones and immunosuppressants,and there was no statistically significant difference in the the use of hormones and immunosuppressants among various groups(P=0.637).Conclusion There is a correlation between the tongue image features of IMN patients and the risk level of disease,and the results will provide an objective reference for the assessment of illness state and traditional Chinese medicine(TCM)syndrome differentiation of IMN patients.With reference to the changes in the tongue image features,the illness state can be precisely identified,which is more accurate than the inspection of four diagnostic methods of TCM.

Objective:To compare the effects of early orthodontic intervention and conventional sequential periodontal-orthodontic treatment to periodontal health in patients with stage Ⅳ periodontitis.Methods:A total of 30 patients with stage Ⅳ periodontitis, who underwent combined periodontal and orthodontic therapies at the Department of Periodontology, the Second Affiliated Hospital of Zhejiang University School of Medicine, from January 2018 to August 2024, were included. Patients who underwent early orthodontic intervention were initiated simultaneously or within one month after supragingival scaling and subgingival root planning ( n=15). While patients in control group accomplished supragingival scaling, subgingival root planning, and corresponding periodontal surgeries to achieve inflammation control before starting orthodontic treatment ( n=15). Periodontal parameters, including clinical attachment loss (CAL), probing depth (PD), and bleeding on probing (+) % [BOP (+) %], were measured at baseline, one year after orthodontic treatment, and at the end of combined periodontal-orthodontic therapy respectively. Improvements in periodontal parameters and differences in tooth loss between the two groups were compared. Results:After receiving combined periodontal-orthodontic treatment, the CAL of the early orthodontic intervention group significantly decreased from (4.39±0.90) mm before treatment to (2.41±0.35) mm at the end of treatment ( t=7.92, P<0.001). Similarly, the PD significantly reduced from (4.20±1.04) mm before treatment to (2.20±0.38) mm at the end of treatment ( t=7.01, P<0.001). The BOP(+)% also showed a significant improvement, decreasing from 89.29% (68.00%, 100.00%) before treatment to 13.04% (7.14%, 17.86%) at the end of treatment ( Z=-3.41, P<0.001). There were no statistically significant differences between the early orthodontic intervention group and control group in terms of baseline mean CAL, mean PD, and BOP(+)% ( t=1.30, P=0.205; t=1.28, P=0.212; Z=0.58, P=0.559). Furthermore, the improvements in CAL and PD between the two groups were not significantly different compared to baseline ( Z=-1.10, P=0.272; Z=-0.93, P=0.351). However, the number of missing teeth was significantly lower in the early orthodontic intervention group than in the control group (χ2=3.96, P=0.047). The duration of combined periodontal-orthodontic treatment in the early orthodontic intervention group was [33.13 (23.37, 36.20) months], which was significantly shorter than that in the control group [37.47 (32.33, 50.90) months] ( Z=2.07, P=0.037). Conclusions:Both early orthodontic intervention and conventional periodontal-orthodontic treatment significantly improved CAL, PD, and BOP(+)% in stage Ⅳ periodontitis patients. Early orthodontic intervention contributed to the preservation of natural teeth and shortened the treatment duration of stage Ⅳ periodontitis.

Objective To investigate the effects of Andai therapy based on metabolomics on people with different constitution of Mongolian Medicine.Methods On the basis of literature research,expert interviews,questionnaires and field investigation on the historical origin,operational methods,clinical effects,indications and contraindications of Andai therapy,non-targeted metabolomics detection was performed on baseline plasma of all included cases by gas chromatography mass spectrometry(GC-MS).The differences in metabolites between the experimental group(three body groups receiving Andai therapy)and the control group(three body groups not receiving Andai therapy)were compared,and functional analysis of related metabolites was conducted,and the factors related to regulatory mechanisms were explored by screening related metabolites and their pathways.Results Andai therapy can significantly reduce the content of harmful metabolites in the experimental group,indicating that it may regulate the level of metabolites in vivo.The response of different constitutions to Andai therapy was different,with statistical significance(P＜0.05).The contents of metabolites such as serotonin and abietic acid in the samples of Heyi constitutions were reduced,while the contents of Xila constitutions and Baganda constitutions showed more complex changes.The effects of Andai therapy on metabolic pathways are mainly reflected in the citric acid cycle,glutathione metabolism and lipid metabolism,which may promote energy metabolism and other physiological processes.Conclusion Andai therapy shows potential in regulating metabolite levels and metabolic pathway activity in vivo,but further studies are needed to fully evaluate the feasibility and effectiveness of its clinical application.

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.

Methods:The clinical data and follow-up results of 56 patients with refractory hyperthyroidism who underwent laparoscopy or open surgery in Affiliated Nanhua Hospital of University of South China from January 2019 to August 2020 were retrospectively analyzed.Results:Among the 56 patients, there were 6 men and 50 women. Thirty-six (64.3%) patients underwent endoscopic surgery and twenty (35.7%) patients underwent open surgery. The operation time was (132.0 ± 32.0) minutes. Intraoperative blood loss was (32.4 ± 27.8) mL. Postoperative parathyroid hormone level was (27.8 ± 18.3) ng/L. Forty-nine (87.5%) patients showed benign pathology results after surgery. After surgery, 14 (25.0%) patients had hypothyroidism, including 7 (12.5%) patients with hyperthyroidism combined with thyroid cancer. There were no patients with permanent hypothyroidism or recurrent laryngeal nerve paralysis. All patients had a good prognosis and satisfactory surgical results.Conclusion:With the update of preoperative preparation methods for hyperthyroidism, the increasing maturity of thyroid surgery technology, and the use of new energy instruments and technologies, surgical treatment is undoubtedly a good treatment method for patients with refractory hyperthyroidism or a suspected malignant tumor.Objevtives:To investigate the indications and clinical efficacy of surgical treatment in patients with refractory hyperthyroidism.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Clinical data of a child with acromesomelic dysplasia Maroteaux type (AMDM) treated in the Department of Pediatrics, Tianjin Medical University General Hospital at November 2018 was retrospectively analyzed.The female child aged 3 years and 3 months old with 83 cm height (-3.84 SD) had clinical manifestations of disproportionate short stature, disproportionate shortening of forearms and forelegs, and stubby fingers and toes.Gene sequencing identified compound heterozygous mutations, c.1640T>A(p.Val547Asp)/c.682G>A(p.Gly228Ser), in the NPR2 gene, which have not been reported in the Human Gene Mutation Database.Their protein function was predicted harmful.The child was diagnosed as AMDM.During the follow-up until 4 years and 8 months old, the child was 90 cm tall (-4.35 SD), with a growth velocity of 4.9 cm/year.She was treated with recombinant human growth hormone (rhGH) treatment for 9 months and regularly followed up.The child was now 98.2 cm height (-3.07 SD) and she had a growth velocity of 10.9 cm/year.This case report enriched the gene mutation spectrum of AMDM.Treatment with rhGH can effectively improve the height of the child, but the long-term effect needs further follow-up and observation.
