This review aimed to provide a comprehensive analysis of the etiology, epidemiology, pathology, and conventional treatment of heterotopic ossification (HO), especially emerging potential therapies. HO is the process of ectopic bone formation at non-skeletal sites. HO can be subdivided into two major forms, acquired and hereditary, with acquired HO predominating. Hereditary HO is a rare and life-threatening genetic disorder, but both acquired and hereditary form can cause severe complications, such as peripheral nerve entrapment, pressure ulcers, and disability if joint ankylosis develops, which heavily contributes to a reduced quality of life. Modalities have been proposed to treat HO, but none have emerged as the gold standard. Surgical excision remains the only effective modality; however, the optimal timing is controversial and may cause HO recurrence. Recently, potential therapeutic strategies have emerged that focus on the signaling pathways involved in HO, and small molecule inhibitors have been shown to be promising. Moreover, additional specific targets, such as small interfering RNAs (siRNAs) and non-coding RNAs, could be used to effectively block HO or develop combinatorial therapies for HO.

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 evaluate the effect of pneumatic logistics transport system(PTS)on the trans-portation efficiency of the transferred samples and the accuracy of the results.Methods The transportation speed,temperature and humidity change of PTS were analyzed by temperature and humidity transmitter.Anti-coagulant samples containing disodium ethylenediaminetetraacetate(EDTA-K2),sodium citrate,lithium hepa-rin and samples containing inert separation gel coagulant were selected.and used respectively for complete blood cell analysis,prothrombin time(PT),activated partial prothrombin time(APTT),troponin T(TnT)and other myocardial markers,as well as the detection of items such as glucose(Glu)and lactate dehydrogen-ase(LDH).According to the transfer mode,they were divided into the manual transfer group and the PTS transfer group,and according to the number of PTS transfers,they were divided into the one-time transfer group,the three-time transfer group and before transfer(control).The differences among each group were statistically analyzed,and 1/3 allowable total error(1/3TEa)was adopted as the criterion for determining the clinical application value.Results There was no statistically significant difference in the changes of tempera-ture and humidity during the transportation process of PTS compared with manual transportation(P＞0.05),but it was significantly faster than manual transportation in terms of transportation time(P＜0.05).Com-pared with before transfer,the differences between the PT,APTT,Glu and LDH items in the one-time trans-fer group and the three-time transfer group were statistically significant(P＜0.01),and their deviations were all much greater than 1/3TEa.However,in the plasma samples,compared with before transport,there were statistically significant differences in Glu and LDH between the one-time transfer group and the three-time transfer group(P＜0.05),but the deviations were all less than 1/3TEa.For the items of TnT,red blood cell count and hematocrit,compared with before transfer,there were statistically significant differences between some groups of the one-time transfer group and the three-time transfer group(P＜0.05),but the deviations were all less than 1/3TEa.Conclusion PTS can significantly improve the transportation efficiency of sam-ples,but it significantly affects the detection of Glu and LDH in plasma samples,which can be improved by u-sing serum sample transportation instead.In addition,PTS also affects the detection of PT and APTT,and it is not recommended to use PTS to transport coagulation specimen.

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.

OBJECTIVE: To explore the impact of age on the genetic variant spectrum and prognosis of patients with previously untreated Diffuse large B-cell lymphoma (DLBCL). METHODS: A retrospective analysis was conducted on the clinical data and follow-up information of 254 previously untreated DLBCL patients from 14 hospitals in the Jiangsu Cooperative Lymphoma Group (JCLG) enrolled from July 2018 and July 2023. Following extraction of DNA from tumor tissue samples, next-generation sequencing (NGS) technique was employed to analyze the genetic variant spectrum of the DLBCL patients, with an evaluation of the relationship between age and genetic variants as well as prognosis. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Nantong University (Ethics No.: 2023-K048-01). RESULTS: The median age of the 254 DLBCL patients was 62 years old, with 55% of patients aged 60 years or above. Clinical evaluation showed that younger (< 60 years) patients had higher complete response (CR) (70% vs. 59%), and objective response rate (ORR) (88% vs. 79%) than older patients, though the difference between the two groups was not statistically. Survival analysis indicated that both the five-year overall survival (OS) (82.7% vs. 71.7%, P = 0.006) and progression-free survival (PFS) (70.6% vs. 50.2%, P < 0.05) rates were significantly higher in younger patients. NGS showed that 99.6% of the patients harbored genetic variants, with PIM1, KMT2D, TP53, MYD88, and CD79B being the most common genes. Age significantly affected the variant frequency of certain genes, with MYC variants serving an adverse prognostic factor for OS in younger patients (P = 0.002), while TP53 (P = 0.024) and BCL2 (P = 0.002) variants significantly impacted OS in older patients. Prognostic analysis identified age ≥ 60 years (HR = 3.439, 95%CI: 1.318~9.874), presence of B symptoms (HR = 2.871, 95%CI = 1.133~7.307), and elevated lactate dehydrogenase (HR = 3.528, 95%CI = 1.231~10.66) as independent adverse prognostic factors. CONCLUSION Age, genetic variants, and clinical factors may significantly affect the prognosis of the DLBCL patients. Younger patients have better survival compared to older patients. Variants of the MYC, BCL2, and TP53 genes are closely associated with poor prognosis.

OBJECTIVE To investigate the effects of different drying aids on the hygroscopic property of extract powder of modified Liujunzi decoction （MLJZD）， and screen the best drying aid. METHODS MLJZD extract was mixed with β-cyclodextrin， microcrystalline cellulose， lactose， arabic gum， maltodextrin， corn starch， mannitol， dextrin， soluble starch and pre-gelatinized starch at the mass ratio of 1∶0.3 and 1∶0.5， respectively. The extract powder was prepared after vacuum drying. Physical fingerprints were established with 8 physical indexes， including moisture content， bulk density， vibrating-solid density， gap rate， Carr index， Hausner ratio， angle of rest and hygroscopicity， and then similarity evaluation was performed. The matrix hotspot map was drawn to analyze the influence of physical indexes on hygroscopicity. The moisture absorption rate of MLJZD extract powder was measured at room temperature for 2， 4， 8， 10 h and 1， 2， 3， 7 d. The moisture absorption rate-time curve was drawn， and the best auxiliary materials were selected by comparison. RESULTS The similarity evaluation results of physical fingerprint showed that the prepared MLJZD extract powder were stable and the similarities were above 0.90. The matrix hotspot analysis showed that there was significant correlation between bulk density and vibratory density and the moisture absorption rate of the MLJZD extract powder （P＜0.05）. The moisture absorption rate-time curve analysis showed that the moisture absorption rate of MLJZD extract powder prepared with the mass ratio of 1∶0.5 was lower than prepared with the mass ratio of 1∶0.3. Under both ratios， lactose showed the best drying aid effect， followed by soluble starch and mannitol. CONCLUSIONS Lactose， as the drying aid （under the mass ratio of 1∶0.5）， can obviously improve the hygroabsorbance effect of the extract powder of MLJZD， which provides a reference for the selection of auxiliary materials for MLJZD solid preparations.

OBJECTIVE To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification. METHODS From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR. RESULTS Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis. CONCLUSION This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.
