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.

Post-traumatic cerebral infarction (PTCI) is a secondary insult which causes global cerebral hypoxia or hypoperfusion after traumatic brain injury, and carries a remarkable high mortality rate. PTCI is usually caused by blunt brain injury with gross hematoma and/or brain herniation. Herein, we present the case of a 91-year-old male who had sustained PTCI following a low-energy penetrating craniocerebral injury due to a nail without evidence of hematoma. The patient survived after a decompressive craniectomy, but permanent neurological damage occurred. This is the first case of profound PTCI following a low-energy penetrating craniocerebral nail injury and reminds clinicians of possibility this rare dreadful complication for care of head-injured patients.

OBJECTIVE: The multidrug resistance 1 (ABCB1, MDR1) gene, encoding P-glycoprotein, is extensively distributed and expressed in various tissues, such as a blood-brain barrier transporter. P-glycoprotein plays an important role in controlling the passage of substances between the blood and brain. The current study aimed to investigate possible associations of functional ABCB1 polymorphisms (C3435T, G2677T and C1236T) with response to antidepressant treatment and serum cortisol levels in Taiwanese patients with major depressive disorder (MDD). METHODS: We recruited 112 MDD patients who were randomized to fluoxetine (n=58, mean dose: 21.4+/-4.5 mg/day) or venlafaxine (n=54, 80.2+/-34.7 mg/day) treatment for 6 weeks. The 21-item Hamilton Depression Rating Scale (HDRS) was administered initially and biweekly after treatment, and cortisol levels were assessed initially and after 6-week antidepressant treatment. RESULTS: The initial HDRS scores and the HDRS scores after six weeks of antidepressant treatment were not significantly different among the different genotypes in each polymorphism of ABCB1. The percentage changes of HDRS scores over time were significantly different in the polymorphisms of ABCB1 G2677T (p=0.002). MDD patients with the G/G genotype of ABCB1 G2677T had a worse antidepressant treatment response. However, the polymorphisms of ABCB1 genotypes were not significantly associated with cortisol levels before and after antidepressant treatment in MDD patients. CONCLUSION: The results suggested that the variants of ABCB1 may influence the short-term antidepressant response in MDD patients. Further details of the underlying mechanisms of ABCB1 in antidepressant treatment remain to be clarified.
