Objective:To investigate the clinical efficacy of three-connections and four-screwings technique in the treatment of high double column acetabular fractures through a single ilioinguinal approach.Methods:A retrospective study was conducted to analyze the data of 42 patients who had been treated for high double column acetabular fractures from June 2017 to June 2020 at Trauma Ward 2, Department of Orthopedics and Traumatology, The First Hospital of Traditional Chinese Medicine of Changde. There were 19 males and 23 females with an age of (42.7±25.6) years. 29 injuries were due to a traffic accident, 12 ones to fall from a height, and one to fall. The time from injury to operation was (4.5±2.1) days. All the patients were treated by the three-connections and four-screwings technique through a single ilioinguinal approach. Briefly, the anterior column was connected and secured to the main bone using 3 routes, and the posterior column was attached and fixated to the anterior column reset using 2 or 3 of the 4 screwings. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, hip function at the last follow-up and complications during the follow-up were recorded.Results:For this cohort, the operation time was (150.0±30.5) min, and intraoperative blood loss (300.0±50.0) mL. According to the Matta scale for postoperative acetabular fracture reduction, 34 cases were excellent, 6 cases good, and 2 cases acceptable, with an excellent and good rate of 95.2% (40/42). After operation one patient had fat liquefaction and wound exudation which responded to drainage and dressing change. The 42 patients were followed up for (15.0±3.4) months. All fractures healed after (11.0±2.0) months. By the modified Merle d'Aubigné & Postel scoring system, the hip function was evaluated at the last follow-up as excellent in 33 cases, as good in 6 cases, and as fair in 3 cases, yielding an excellent and good rate of 92.9% (39/42).Conclusions:In the treatment of high double column acetabular fractures, the three-connections and four-screwings technique through a single ilioinguinal approach can lead to fine reduction and rigid fixation by lag screw compression and neutralization plate protection. Consequently, early functional exercises can be performed to secure good therapeutic outcomes for the patients.

Ameloblastoma is a benign tumor characterized by locally invasive phenotypes,leading to facial bone destruction and a high recurrence rate.However,the mechanisms governing tumor initiation and recurrence are poorly understood.Here,we uncovered cellular landscapes and mechanisms that underlie tumor recurrence in ameloblastoma at single-cell resolution.Our results revealed that ameloblastoma exhibits five tumor subpopulations varying with respect to immune response(IR),bone remodeling(BR),tooth development(TD),epithelial development(ED),and cell cycle(CC)signatures.Of note,we found that CC ameloblastoma cells were endowed with stemness and contributed to tumor recurrence,which was dominated by the EZH2-mediated program.Targeting EZH2 effectively eliminated CC ameloblastoma cells and inhibited tumor growth in ameloblastoma patient-derived organoids.These data described the tumor subpopulation and clarified the identity,function,and regulatory mechanism of CC ameloblastoma cells,providing a potential therapeutic target for ameloblastoma.

Objective To analyze the correlation between serum levels of long non-coding RNA cyclin-de-pendent kinase inhibitor 2B antisense RNA 1(lncRNA CDKN2B-AS1),and microRNA-184(miR-184)in pa-tients with acute coronary syndrome(ACS)and the occurrence of coronary artery restenosis(RS)after percu-taneous coronary intervention(PCI)treatment.Methods A total of 288 ACS patients who underwent PCI treatment in the hospital from February 2020 to March 2023 were selected.According to the results of follow-up angiography at 6 months after surgery,they were separated into a RS group of 96 cases and a non RS group of 192 cases.The quantitative real-time PCR(qRT-PCR)method was applied to detect the relative expression levels of serum lncRNA CDKN2B-AS1 and miR-184.Pearson correlation was applied to analyze the correlation between serum lncRNA CDKN2B-AS1 and miR-184.The factors affecting the occurrence of RS in ACS pa-tients after PCI were analyzed using multivariate Logistic regression analysis.Receiver operating characteristic(ROC)curve was applied to analyze the evaluation value of serum lncRNA CDKN2B-AS1 and miR-184 for the occurrence of RS in ACS patients after PCI.Results Compared with the non RS group,the serum lncRNA CDKN2B-AS1 level in the RS group was obviously increased,while the miR-184 level was obviously reduced(P＜0.05).There were statistically significant differences in the levels of high-sensitivity C-reactive protein(hs-CRP),interleukin-18(IL-18),total bilirubin(TBIL),and cardiac troponin Ⅰ(cTnⅠ)between the two groups(P＜0.05).Pearson correlation analysis showed that there was a obvious negative correlation(r=-0.427,P＜0.05)between the expression levels of serum lncRNA CDKN2B-AS1 and miR-184 in ACS pa-tients.Multivariate Logistic regression analysis results showed that lncRNA CDKN2B-AS1,hs-CRP,IL-18,and cTnⅠ were risk factors affecting the occurrence of RS in ACS patients after PCI,while miR-184 and TBIL were protective factors affecting the occurrence of RS in ACS patients after PCI(P＜0.05).ROC curve re-sults showed that the area under the curve(AUC)of serum lncRNA CDKN2B-AS1,miR-184,and their com-bination in evaluating the occurrence of RS in ACS patients after PCI was 0.787,0.844,and 0.929,respective-ly,and the AUC of the combined evaluation the occurrence of RS in ACS patients after PCI was obviously higher than those of serum lncRNA CDKN2B-AS1 and miR-184 alone(Zcombination-lncRNACDKN2B-AS1=4.490,Zcombination-miR-184=3.429,all P＜0.05).Conclusion The serum lncRNA CDKN2B-AS1 level in ACS patients is obviously elevated,while miR-184 level is obviously reduced,which is correlated with the occurrence of RS in ACS patients after PCI.Both are factors that affect the occurrence of RS in ACS patients after PCI,and the combination of the two has better evaluation effect on the occurrence of RS in ACS patients after PCI.

Objective:To determine the content of the released nickel ion through the 7 extraction media to extract the Ni-Ti wires and to plot the curve of the released nickel ion so as to identify a leaching medium that can be substituted for blood for in vitro Ni release evaluation. Methods:The release of Ni through microwave digestion/inductively coupled plasma mass spectrometry (ICP-MS) in the goat serum was determined. Because of the high content of Ni release, it could be determined by diluting the extraction medium, and other extraction media could be determined directly. Ni release standard curves were plotted by the release amount and different time point variables. Though the different extraction media Ni release curves confirm the specificity of extraction media instead of blood.Results:By analyzing the Ni release curves of seven leaching media, it was found that none of these seven extraction media was suitable for the evaluation of Ni release in in vitro leaching media. Considering the safety of the leaching medium and the simplicity of preparation, hydrochloric acid solution was chosen as the leaching medium, but the concentration needed to be diluted accordingly. Finally, a hydrochloric acid solution was created as an alternative to blood for the in vitro study of Ni release from Ni-Ti alloy cardiovascular products, with a volume fraction of 0.005%. Conclusions:The in vitro leaching medium that can replace blood was found to be hydrochloric acid for the time being, but its concentration was too high, resulting in too much Ni release as well, which deviated from the actual situation. Therefore, the hydrochloric acid solution was diluted step by step, and the Ni release curve was examined until it was close to the clinical release level, and the actual concentration was determined, thus laying a solid foundation for the subsequent evaluation of the safety and risk.

Objective:To evaluate the efficacy and safety of Xiao′er Huangjin Zhike Granules in the treatment of cough caused by acute bronchitis in children, which is defined in TCM terms as a syndrome of phlegm-heat obstructing the lung.Methods:This was a block-randomized, double-blind, placebo-controlled, multicenter clinical trial.From January 2022 to September 2023, 359 children aged 3 to 7 years old diagnosed as acute bronchitis (lung-obstructing phlegm-heat syndrome) were enrolled from 21 participating hospitals and randomly assigned to the experimental group and placebo group in a 3︰1 ratio, and respectively treated with Xiao′er Huangjin Zhike Granules and its matching placebo.Cough resolution/general resolution rate after 7 days of treatment was used as the primary efficacy outcome for both groups.Results:(1)On the seventh day of treatment, the rate of cough disappearance/basically disappearance in the experimental group and placebo group were 73.95% and 57.61% retrospectively, which had statistically significance ( P=0.001).(2)After 7 days of treatment, the median duration of cough disappearance/basic disappearance were 5 days and 6 days in the two groups , with a statistically significant difference ( P=0.006).The area under the curve of cough symptom severity time was 7.20 ± 3.79 in the experimental group and 8.20±4.42 in the placebo group.The difference between the two groups was statistically significant ( P=0.039).(3) After 7 days of treatment, the difference between TCM syndrome score and baseline was -16.0 (-20.0, -15.0) points in the experimental group and -15.0 (-18.0, -12.0) points in the placebo group, with significant difference between the two groups ( P=0.004).In the experimental group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 49.04%, 28.35%, 16.48% and 6.13% severally; and in the placebo group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 38.04%, 26.09%, 29.35%, and 6.52% separately, which had statistically significant ( P=0.014).(4) There was no significant difference in the incidence of adverse events or adverse reactions during the trial between both groups.Moreover, while adverse reactions in the form of vomiting and diarrhea were occasionally reported, no serious drug-related adverse event or adverse reaction was reported.(5)The tested drug provided good treatment compliance, showing no statistically significant difference from the placebo in terms of compliance rate. Conclusions:Based on the above findings, it can be concluded that Xiao′er Huangjin Zhike Granules provides good safety, efficacy, and treatment compliance in the treatment of cough caused by acute bronchitis, and lung-obstructing phlegm-heat syndrome, in children.
