Academic Journal of Second Military Medical University 2019;40(10):1135-1138
Objective: To explore the feasibility and clinical effects of Double-Pulley technique combined with 8-shaped tension band in teatment of comminuted fractures of distal patellar pole. Methods: From Jan. 2017 to Apr. 2018, 10 patients (6 males and 4 females) were treated with Double-Pulley technique combined with 8-shaped tension band in our hospital. The ages of patients ranged from 28 to 58 years old, with an average of (36.4± 11.4) years old. The average time from injury to surgery was (2.8 ± 1.1) d, ranging from 1 to 5 d. The injury cause was traffic accident in 6 cases, falling iniury in 3 cases, and sport injury in 1 case. Bostman's patellar fracture function evaluation system was used to evaluate the postoperative knee joint function. The clinical evaluation indexes included the excellent and good rate of Bostman's patellar fracture function score, and X-ray examination results and knee mobility during follow-up. Results: All patients were followed up for 16 to 24 months. The incision of all patients healed well, and no anterior knee pain or complications were found. Six months after surgery, X-ray examination showed that the patellar fracture healing of 10 patients were all osteonal union. Six months after surgery, the flexion range of knee joint was 132.0°±12.3°, and Bostman's patellar fracture function score was 28.5±1.8, with the excellent and good rate being 100% (excellent in 9 cases and good in 1 case). Conclusion: Double-Pulley technique combined with 8-shaped tension band is effective and reliable in the treatment of comminuted fractures of distal patellar pole, and the patients can start functional exercise early after surgery.

Immortalized human precartilaginous stem cells (IPSCs) were established to provide stable cell resource for the study of the molecular mechanism of gene targeting on the differentiation of PSCs.Plasmid pCMVSV40T/PUR containing simian virus 40 large T antigen gene (SV40Tag) was transfected into human PSCs by using lipofectin transfection.Colonies were isolated by puromycin selection and expanded by multiple passages,lmmunohistochemistry,RT-PCR and Southern blotting were used to identify the transfected cells and to detect the expression and integration of SV40Tag in expanded cell lines.The positive colonies were isolated and subcultured,designated immortalized precartilaginous stem cells (IPSCs),which were confirmed as fibroblast growth factor receptor-3 (FGFR-3) positive cells by immunohistochemistry and RT-PCR.SV40Tag cDNA was found in cultured IPSCs of passage 8 by Southern blotting,and the expressions of SV40Tag mRNA and protein were confirmed by RT-PCR.These findings suggested that IPSCs strain with SV40Tag was constructed successfully.

Purpose:
This study aimed to evaluate the effectiveness of an interactive virtual reality (VR) play intervention including instructional play and emotional catharsis play sessions in reducing children's pain and fear during intravenous placement.
Methods:
A randomized controlled trial with parallel groups was conducted. The sample consisted of 134 hospitalized children aged 6–12 years (intervention group: n = 69; comparison group: n = 65). The intervention involved one immersive intravenous scene in VR before the actual intravenous placement and one emotional catharsis VR play after injection. The comparison group received an educational photo book about intravenous placement before receiving intravenous placement. The children and their caregivers rated their pain and fear by using the Wong–Baker FACES Pain Rating Scale and the Children's Fear Scale. The time required for successful intravenous insertion was also compared between the two groups.
Results:
Children's pain (p = .028) and fear scores (p = .004) were significantly lower in the intervention group than in the comparison group. Their caregivers' pain and fear scores (both p < .001) were significantly lower in the intervention group. The time required for successful intravenous insertion did not differ significantly between the intervention and comparison groups.
Conclusions
The interactive play intervention with VR effectively reduced children's levels of pain and fear during the intravenous placement procedure. The results of this study can serve as a reference for the implementation of a feasible, child-friendly care practice for clinical intravenous placement in school-aged children.

Lung cancer associated with cystic airspaces (LCCA) is a type of lung cancer characterized by the presence of cystic cavities in or around the tumor on imaging. Due to its high potential for misdiagnosis or underdiagnosis, the prognosis of LCCA patients is poor, necessitating further large-scale clinical studies to elucidate its characteristics. Currently, four imaging classification systems exist, and there has been a progressive increase in attention towards LCCA, particularly with regard to the study of its imaging features. The results indicate a correlation between the pathological features and imaging findings of LCCA; however, research on driver gene mutations and molecular subtyping associated with lung cancer remains insufficient. Due to the challenges associated with early diagnosis and the poorer prognosis compared to general types of lung cancer, this paper comprehensively reviews the research progress on LCCA, including its definition, etiology, pathogenesis, imaging features, histological and pathological features, treatment, and prognosis, aiming to serve as a valuable resource for clinical decision-making.

Aim To screen the mechanism of Yiqi- Bushen-Tiaozhi formula ( YBTF) in treating non-alcoholic steatohepatitis ( NASH) by network pharmacology analysis and to verify it by animal experiments. Methods TCMSP database and HPLC-MS analysis were used to mine the active ingredients and targets of YBTF; GSE89632 dataset was used to screen the differential expressed genes ( DEGs) between the normal and the NASH groups; GeneCards and DisGeNET databases were used to screen NASH-related disease genes. The intersection genes of the three are the target genes of YBTF treatment of NASH. The intersection gene of the three sets of genes was the target gene of YBTF in treating NASH. GO, KEGG, DO enrichment analysis, protein-protein interaction network, and network topology analysis were used to identify the hub genes of YBTF in the treatment of NASH. Molecular docking was used to judge whether cmcial target genes, active ingredients could be combined and exer ted a curative effect; Oil red 0 and HE staining were used to determine whether YBTF could treat NASH mice; (3-galactosidase ( SA- (3-Gal) test was used to determine whether NASH mice had hepatocyte senescence and whether YBTF improved senescence; West-ern blot. Quantitative Real-time PGR ( qRT-PCR) combined with sequencing results were used to verify whether YBTF could regulate the expression of the essential target genes screened from the protein and RNA levels. Results YBTF could improve cellular aging and treat NASH through CDKN1A. Conclusion The rational application of Traditional Chinese medicine (TCM) network pharmacology and experiments can provide new ideas and directions for studying the mechanism of YBTF.

As the utilization of computed tomography in lung cancer screening becomes more prevalent in the post-pandemic era, the incidence of multiple primary lung cancer (MPLC) has surged in various countries and regions. Despite the continued application of advanced histologic and sequencing technologies in this research field, the differentiation between MPLC and intrapulmonary metastasis (IM) remains challenging. In recent years, the specific mechanisms of genetic and environmental factors in MPLC have gradually come to light. Lobectomy still predominates in the treatment of MPLC, but the observation that tumor-specific sublobar resection has not detrimentally impacted survival appears to be a viable option. With the evolution of paradigms, the amalgamated treatment, primarily surgical, is an emerging trend. Among these, stereotactic ablative radiotherapy (SABR) and lung ablation techniques have emerged as efficacious treatments for early unresectable tumors and control of residual lesions. Furthermore, targeted therapies for driver-positive mutations and immunotherapy have demonstrated promising outcomes in the postoperative adjuvant phase. In this manuscript, we intend to provide an overview of the management of MPLC based on the latest discoveries.
