Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder primarily caused by pathogenic variants in the TSC1 or TSC2 genes. It is characterized by multisystem hamartomatous lesions and neuropsychiatric manifestations. Here we report a young male patient with TSC involving multiple organs, caused by a heterozygous frameshift mutation in TSC2 (c.2071delC, p.Arg691Alafs^*7). The patient initially presented with classic facial angiofibromas and hypomelanotic macules, and subsequently developed psychiatric and behavioral disturbances with auditory hallucinations. Neuroimaging revealed an intracranial mass lesion, which was confirmed as a subependymal giant cell astrocytoma on postoperative histopathology following surgery performed at an outside institution. After admission, the patient underwent a comprehensive diagnostic workup, and multidisciplinary treatment evaluation revealed extensive multisystem involve-ment, including the nervous system, skin, kidneys, lungs, heart, eyes, pancreas, liver and bones. Combined with relevant literature, this article discusses the molecular mechanisms, clinical phenotypes, and comprehensive management of TSC, in order to provide a reference for the standardized and individualized management of this disease.

Diabetic nephropathy（DN） is a common and severe microvascular complication of diabetes. In recent years， the classical herbal formula Shenqi dihuang decoction has demonstrated unique advantages in the clinical treatment of DN. This article conducts a systematic review of the mechanisms of action and clinical applications of Shenqi dihuang decoction in the treatment of DN. It reveals that the mechanism by which this formula improves DN involves multi-target synergistic regulation. For instance, Shenqi dihuang decoction exerts multiple pharmacological effects by regulating signaling pathways including phosphatidy linostiol 3-kinase/protein kinase B， AMP-activated protein kinase/silent information regulator 1/forkhead box O1， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 pathways.These effects include regulating glucose and lipid metabolism， inhibiting oxidative stress， reducing inflammation， improving insulin resistance， modulating cell death （apoptosis/autophagy/ferroptosis/pyroptosis）， and preventing renal fibrosis. Existing clinical studies indicate that Shenqi dihuang decoction and its modified formulas， alone or in combination with other therapeutic methods， can significantly improve glucose and lipid metabolism， reduce proteinuria， and delay renal function decline in patients with DN. These effects are superior to those of Western medicines such as irbesartan， valsartan， and empagliflozin， and the treatment demonstrates good safety. Future research should leverage systems biology and artificial intelligence technologies to further elucidate the integrated mechanisms in the treatment of DN by Shenqi dihuang decoction， thereby advancing the precision and standardization of its clinical application.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To screen the influencing factors associated with adverse clinical out-comes in hospitalized elderly patients with Alzheimer's disease(AD)using LASSO-Logistic regression analysis and to construct a nomogram prediction model.Methods A retrospective selection of 214 hospitalized elderly patients with AD who visited the Department of Geriatric Medicine in the hospital from February 2021 to March 2023 was conducted,and clinical data of all patients were collected.Patients were divided into adverse events group(n=53)and non-adverse events group(n=161)based on the occurrence of adverse clinical outcomes.After variable screening using LASSO regres-sion,multivariate Logistic regression analysis was performed to identify independent factors influen-cing adverse clinical outcomes in hospitalized elderly patients with AD.A Nomogram model for pre-dicting adverse clinical outcomes in these patients was established based on the results of multivariate analysis.The predictive performance,calibration,and clinical utility of the Nomogram model were evaluated using the concordance index,calibration curve,and decision curve analysis(DCA).The diagnostic performance of the Nomogram model for adverse clinical outcomes in hospitalized elderly patients with AD was assessed using the receiver operating characteristic(ROC)curve and the area under the curve(AUC).Results LASSO-Logistic regression analysis revealed that the Mini-Men-tal State Examination(MMSE)score was an independent protective factor against adverse clinical outcomes in hospitalized elderly patients with AD(P＜0.05),while the Charlson Comorbidity In-dex(CCI score),creatinine,urea,and fasting blood glucose(FBG)levels were all independent risk factors for adverse clinical outcomes in these patients(P＜0.05).The Nomogram model con-structed based on the influencing factors screened by LASSO-Logistic regression analysis showed a concordance index of 0.994(95％CI,0.958 to 1.000)for predicting adverse clinical outcomes in hospitalized elderly patients with AD.The Hosmer-Lemeshow test results indicated x2=1.909,P=0.984,suggesting good model fit.The DCA result demonstrated that the model had favorable threshold probabilities and net clinical benefits.Conclusion The Nomogram model for predicting clinical outcomes in elderly inpatients with AD constructed based on LASSO-Logistic regression anal-ysis exhibits high predictive value,and can be used to forecast the occurrence of adverse clinical outcomes in these patients.

Objective To explore the application effect of the dual-track nursing intervention model in the treatment process of children with lobar pneumonia.Methods A total of 186 children with lobar pneumonia were selected and randomly divided into control group and intervention group u-sing a double-blind method,with 93 cases in each group.The control group received conventional nursing intervention,while the intervention group implemented the dual-track nursing intervention model on the basis of conventional nursing.This model included the establishment and training of nurs-ing teams,personalized nursing plans,health education,and psychological support.Outside the hos-pital,it emphasized family support,regular follow-up guidance,and community-based collaborative ed-ucation.Both groups received a 3-week intervention.The improvement times of clinical symptoms,hos-pital stay,pulmonary function indicators before and after nursing,treatment compliance,and family members' satisfaction with nursing were compared and analyzed between the two groups.Results The fever resolution time[(3.89±0.96)d],cough relief time[(6.21±1.34)d],disappearance time of pulmonary rales[(7.89±1.56)d],and hospital stay duration[(9.45±1.89)d]in the intervention group were all shorter than those in the control group[(5.23±1.14),(7.45±1.67),(9.32±2.01),and(11.28±2.35)d,respectively],with statistically significant differences(P＜0.05).After nursing,the forced expiratory volume in one second(FEV1)[(1.51±0.22)L],forced vital capacity(FVC)[(1.75±0.25)L],and FEV1/FVC[(94.12±5.65)％]in the intervention group were all higher than those in the control group[(1.42±0.15)L,(1.66±0.22)L,and(85.73±8.41)％,respectively],with statistically significant differences(P＜0.05).The scores for exami-nation cooperation[(23.91±3.82)points],nursing cooperation[(24.19±4.03)points],standardized medication use[(24.26±3.94)points],and rational diet[(23.77±3.62)points]in the intervention group were higher than those in the control group[(20.16±3.53),(19.64±3.46),(23.05±3.68),and(18.85±3.41)points,respectively],with statistically significant differences(P＜0.05).The satisfaction rate of family members with nursing work in the intervention group was higher than that in the control group,with a statistically significant difference(98.92％versus 89.25％,P＜0.05).Conclusion The dual-track nursing intervention model has a signifi-cant application effect in children with lobar pneumonia.It can accelerate their recovery process,improve treatment compliance,promote pulmonary function improvement,and enhance family mem-bers' satisfaction.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

Objective To explore the efficacy and safety of"ditching and ridge removal"with 450 nm semiconductor blue laser in the treatment of large volume benign prostatic hyperplasia(BPH),in order to promote the clinical application of this method.Methods A retrospective study was conducted on 30 patients with large volume BPH treated with"ditching and ridge removal"with 450 nm semiconductor blue laser in Yingsheng Branch of Tai'an Central Hospital during Sep.and Dec.2023.The laser operation time,level of hemoglobin before and after operation,bladder irrigation time after operation,urinary catheter indwelling time,postoperative hospital stay,and intraoperative and postoperative complications were recorded.The changes of international prostate symptom score(IPSS),quality of life scale(QoL)score,maximum urinary flow rate(Qmax)and post-void residual volume(PVR)were compared before and 1 month after operation.Results The volume of prostate was(104.5±14.52)mL,the laser operation time was(20.13±2.98)min,and the bladder irrigation time was(20.27±2.56)h.The catheter was removed in all patients 2 days after operation,and all patients were discharged 3 days after operation.One month after operation,the IPSS,QoL,Qmax and PVR were significantly improved as compared with those before operation(P＜0.05).No complications occurred during the follow-up.Conclusion"Ditching and ridge removal"with 450 nm semiconductor blue laser is a new,safe and effective method in the treatment of large volume BPH.

Objective To clarify whether the use of dynamic coronary artery roadmap(DCR)technology in a low-dose mode with 7.5 frames per second during coronary intervention can further reduce the total radiation dose,fluoroscopy time,and contrast agent usage.Methods A total of 94 patients,who received coronary angiography at the Shanghai Tongji Hospital of China between July 2022 and December 2022,were enrolled in this study.The patients were randomly divided into DCR group(n=53)and control group(n=41).DCR technology was used in the DCR group to guide the performance of percutaneous coronary intervention(PCI),while low-dose mode coronary angiography was adopted in the control group.The total air kerma(AK),dose-area product(DAP),intraoperative fluoroscopy time,and contrast agent usage were compared between the two groups.Results In the DCR group AK was(597.9±222.8)mGy,which was significantly lower than(717.0±326.8)mGy in the control group(P=0.039);DAP was(33.2±13.3)Gycm2/s,which was also remarkably lower than(41.3±21.5)Gycm2/s in the control group(P=0.027).In the DCR group and the control group,the intraoperative fluoroscopy time was(9.8± 3.3)min and(12.1±4.3)min respectively(P＜0.01),and the contrast agent usage was(122.3±19.0)mL and(130.5± 28.5)mL respectively(P=0.116).Conclusion In a low-dose mode during coronary intervention,the use of DCR technology can further reduce radiation dose,fluoroscopy time,and contrast agent usage.(J Intervent Radiol,2024,33:236-239)
