In infants with severe bronchopulmonary dysplasia(sBPD),severe pulmonary lobar emphysema may occur as a complication,contributing to significant impairment in ventilation.Clinical management of these infants is extremely challenging and some may require lobectomy to improve ventilation.However,prior to the lobectomy,it is very difficult to assess whether the remaining lung parenchyma would be able to sustain adequate ventilation postoperatively.In addition,preoperative planning and perioperative management are also quite challenging in these patients.This paper reports the utility of selective bronchial occlusion in assessing the safety and efficacy of lobectomy in a case of sBPD complicated by severe right upper lobar emphysema.Since infants with sBPD already have poor lung development and significant lung injury,lobectomy should be viewed as a non-traditional therapy and be carried out with extreme caution.Selective bronchial occlusion test can be an effective tool in assessing the risks and benefits of lobectomy in cases with sBPD and lobar emphysema.However,given the technical difficulty,successful application of this technique requires close collaboration of an experienced interdisciplinary team.

Objective To explore the clinical efficacy and safety of early surgical treatment for spinal thoracolumbar fracture without nerve injury.Methods The clinical data of 80 patients with spinal thoracolumbar fracture without nerve injury who were admitted to the department of spinal surgery in our hospital were retrospectively analyzed.According to the different operation timing,those who underwent surgery within 72 hours after fracture were included in the early operation group(n=41),and those who underwent surgery 72 hours to 2 weeks after fracture were included in the elective operation group(n=39).All operations were performed through the Wiltse approach for short-segment pedicle screw fixation on the injured vertebra.The operation time,intraoperative blood loss,hospital stay and incidence of complication of the two groups were compared.The visual analogue scale(VAS)scores,Oswestry disability index(ODI),compression rate of the anterior edge height of the injured vertebra,and the Cobb angle in the sagittal position of the injured vertebra before surgery,1 week after surgery and 1 year after surgery were compared between the two groups.The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery were compared between the two groups.Results There was no significant difference in the operation time,intraoperative blood loss or total incidence of complications between the two groups(P>0.05).The hospital stay in the early operation group was shorter than that in the elective operation group,and the difference was statistically significant(P<0.05).The VAS scores and ODI 1 week and 1 year after surgery of the two groups were better than those before surgery,and the differences were statistically significant(P<0.05).There was no significant difference in the VAS scores or ODI at each time point before and after surgery between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the two groups were lower/smaller than those before surgery,with statistically significant differences(P<0.05).There was no statistically significant difference in the compression rate of the anterior edge height or Cobb angle before surgery in the sagittal position of the injured vertebrae between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were lower/smaller than those in the elective operation group,and the differences were statistically significant(P<0.05).The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were better than those in the elective operation group,and the differences were statistically significant(P<0.05).Conclusion Early surgical treatment for spinal thoracolumbar fracture without nerve damage is safe,it can significantly shorten hospitalization time,obtain good fracture reduction quality and definite therapeutic effects.However,a comprehensive preoperative evaluation of the patients' condition is necessary to ensure surgical safety.

The purpose of this study was to identify the tick species native to Xindi Township,Yumin County,Xinjiang,China.Preliminary morphological identification of parasitic ticks collected from animals in the area was conducted with an ultra-depth of field three-dimensional VHX 600 digital stereo microscope.Total DNA of the ticks was extracted,amplified by PCR based on the COI and ITS2 gene loci,and the posi-tive PCR products were sequenced.The sequence were a-ligned with reference sequences from the NCBI database were aligned with the Basic Local Alignment Search Tool.A genet-ic phylogenetic tree was generated with the neighbor-joining method of MEGA 7.0 software to determine the evolutionary biological characteristics of ticks.Morphological identification showed that the ticks collected from Xindi Township of Yu-min County were consistent with the characteristics of Hya-lomma asiaticum.An evolutionary tree based on the COI and ITS2 gene sequences showed that the ticks collected in this study were clustered with known H.asiaticum sequences.The PCR products of COI and ITS2 were sequenced and compared,which confirmed that the collected tick species were H.asiaticum,in agreement with the morphological and molecular biological results.These findings help to clarify the distribution of ticks in Xindi Township of Xinjiang,and provide basic data for the analysis of tick genetic and evolutionary characteristics,as reference for surveillance and control of ticks in the Xinjiang Uygur Autonomous Region.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis. Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA. The non-perfused volume (NPV) was compared between CEUS and dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) following ablation. Therapeutic efficacy and safety were evaluated at 3-, 6-, and 12-month follow-ups. Additionally, this study explored the correlations between pre-treatment CEUS features and a volume reduction ratio indicating sufficient ablation, defined as 50% or more at the 3-month follow-up. Results: No significant differences in NPV were noted between CEUS and DCE-MRI immediately after MWA and during follow-up (all P>0.05). At the 3-month follow-up, the median VRRs for the uterus and adenomyosis were 33.2% and 63.9%, respectively. Sufficient ablation was achieved in 69.2% (36/52) of adenomyosis cases, while partial ablation was observed in the remaining 30.8% (16/52). The identification of non-enhancing areas on pre-treatment CEUS was associated with sufficient ablation (P=0.016). At the 12-month follow-up, significant decreases were observed in both the uterine and adenomyosis volumes (all P<0.001). Dysmenorrhea and menorrhagia were significantly alleviated at 12 months, and no major complications were encountered. Conclusion CEUS can be used to evaluate the ablation zone of focal adenomyosis that has been treated with MWA, similarly to DCE-MRI. The identification of non-enhancing areas on pretreatment CEUS indicates satisfactory treatment outcomes.

Objective:To compare the surgical efficacy of pericardial soft ring tricuspid valvuloplasty with DeVega and artificial valvuloplasty.Methods:227 patients undergoing tricuspid valvuloplasty due to rheumatic heart disease complicated with functional tricuspid valve insufficiency were retrospectively analyzed and divided into 3 groups according to tricuspid valvuloplasty dynamic cohort(pericardial ring group, 89 cases; the artificial flap ring group, 61 cases, and the DeVega group, 77 cases) were matched 1∶1 for propensity score(match A: pericardial ring group and artificial flap ring group; match B: pericardial ring group and DeVega group), the successful matching was included in follow-up and data collection, and cases with incomplete case data during follow-up were removed from the study cohort in pairs according to matching conditions. The results of follow-up 1 month, 6 months and 24 months after surgery were compared.Results:1 month after operation: the tricuspid valve regurgitant in all groups was significantly reduced or even disappeared compared with that before operation, and the right atrium and right ventricle were also smaller than that before operation, with statistical significance( P<0.05). 6 months after surgery: There was no statistical significance in the area of tricuspid regurgitation and right atrial/indoor diameter between all groups compared with the results one month after surgery( P>0.05), and there was no statistical significance in the recurrence rate of tricuspid regurgitation between all groups( P>0.05). 24 months after surgery: There were no significant differences in the recurrence rate of tricuspid regurgitation, area of tricuspid regurgitation and right atrial/indoor diameter between the two groups in matching A( P>0.05). There was no statistical significance in the right atrial/indoor diameter between the matched pericardial ring group and the Devega group, but the tricuspid valve regurgentation area of the Devega group at 24 months after surgery was higher than that of the Devega group at 1 month after surgery, and the difference was statistically significant( P<0.05). The regurgitation area and recurrence rate of tricuspid valve were significantly higher than those of pericardium-TVP group( P<0.05). Conclusion:Pericardial soft ring tricuspid valvuloplasty can effectively correct functional tricuspid valvuloplasty and reverse right heart remodeling, which is an effective tricuspid valvuloplasty.
