OBJECTIVE:
To explore short-term clinical efficacy of minimally invasive diagnosis and treatment system for hallux valgus in guiding the treatment of hallux valgus.
METHODS:
From March 2021 to November 2023, 68 patients (136 feet) with hallux valgus were treated under guidance of minimally invasive diagnosis and treatment system, including 12 males and 56 females;aged from 25 to 68 years old with an average of (42.5±8.5) years old, the course of disease ranged from 3.2 to 15.6 years with an average of (10.3±2.6) years. The changes of hallux valgus angle (HVA) and intermetatarsal angle (IMA), visual analog scale (VAS) and American Orthopaedic Foot Ankle Society (AOFAS) forefoot score were recorded and compared before operation and 12 months after operation.
RESULTS:
Sixty-five patients (130 feet) were followed up for 12 to 15 months with an average of (13.8±0.5) months, 3 patients (6 feet) were not followed up as required. HVA and IMA improved from (35.5±3.5) ° and (12.5±2.0) ° before operation to (10.5±2.5) ° and (8.5±1.5) °12 months after operation, respectively, with statistically significant differences (P<0.05);VAS decreased from (5.5±1.2) before operation to (1.2±0.5) at 12 months after operation, and the difference was statistically significant (P<0.05);AOFAS forefoot score increased from (50.6±5.1) before operation to (93.8±5.6) at 12 months after operation, with a statistically significant difference (P<0.05). Among them, 102 feet were got excellent result, 24 feet good, and 4 feet fair. Two patients were developed calf intermuscular vein thrombosis, and were cured after 3 months of symptomatic treatment.
CONCLUSION
Under the guidance of minimally invasive diagnosis and treatment system for hallux valgus, the treatment of HV could obviously improve HVA and IMA, and significantly alleviate pain symptoms, and accelerate functional recovery.

Objective:To investigate a new method for rapid detection of the MYOD1 L122R mutation and to analyze the clinical and pathological characteristics of mutation-positive rhabdomyosarcoma.Methods:A MYOD1 mutation detection kit was developed using allele-specific Taqman fluorescence probe technology. A total of 80 rhabdomyosarcoma samples diagnosed at Beijing Children′s Hospital, Capital Medical University from June 2022 to June 2023 were collected for testing. The detection sensitivity, specificity, and consistency rate of the kit were compared with those of the gold standard Sanger sequencing. The demographic, histopathological, and molecular genetic characteristics of patients with MYOD1 mutations were analyzed.Results:Among the 80 rhabdomyosarcoma cases, there were 46 males and 34 females, with an age of onset ranging from 0 to 16 years [mean (6.0±4.4) years], including 32 embryonal rhabdomyosarcoma, 18 alveolar rhabdomyosarcoma, and 30 spindle cell/sclerosing rhabdomyosarcoma. The new kit screened a total of 11 mutations, of which 10 were spindle cell/sclerosing rhabdomyosarcoma and one was embryonal rhabdomyosarcoma. Patients with MYOD1 mutations were typically older (four cases over 10 years old) but could also occur in young children (the youngest being 3-year and 2-month-old). The primary sites were the head and neck region in eight cases, limbs in two cases, and pelvic cavity in one case. Among the six patients with available staging information at initial diagnosis, one was classified as stage 2 and five were stage 3, all of which were intermediate risk. Among the 11 mutation patients, six had recurrence and metastasis, with three deaths; the remaining patients had not shown tumor progression until last follow-up. Compared with the wild type group, the expression level of MYOD1 in mutation patients increased significantly ( χ2=10.66, P=0.01), while the event-free survival rate ( χ2=9.925, P<0.01) and overall survival ( χ2=4.53, P=0.03) rate decreased. Compared with Sanger sequencing, the kit achieved 100% sensitivity and specificity. The kit had a minimum mutation content detection limit of 2% and the reaction could be finished within 2 hours. Additionally, this kit might also be used to detect the expression of MYOD1, thereby aiding the diagnosis of rhabdomyosarcoma. Conclusions:The study has established a new method for accurate and rapid detection of MYOD1 mutation in rhabdomyosarcoma, particularly suitable for the formalin-fixed and paraffin-embedded samples in clinical settings. MYOD1 mutations more likely occur in spindle cell/sclerosing rhabdomyosarcoma of the head and neck region in children. Patients with MYOD1 mutations have an extremely poor prognosis, which is independent of clinical staging and grading. MYOD1 mutation detection in rhabdomyosarcoma has significant value for auxiliary diagnosis and prognostic assessment.

Objective:To analyze the expression of long-chain non-coding RNA U73166 in lung cancer tissues and its relationship with patients′ prognosis, and to explore the effects of silencing U73166 on proliferation and invasion of lung cancer H1299 cells and its regulatory mechanism. Methods:The expression level of U73166 in lung cancer tissues and normal tissues, as well as its correlation with lung cancer patients′ overall survival, were analyzed using the gene expression profiling interactive analysis (GEPIA) database. After culturing, H1299 cells were divided into a control group and a transfection group based on treatment conditions, and were transfected with 25 μmol/L of U73166 negative control and U73166 inhibitor, respectively. The effects of silencing U73166 on the relative expression of U73166 and microRNA-618 ( miR-618) genes in H1299 cells were assessed by real-time reverse transcription-PCR method. A cell counting kit-8 assay was used to evaluate the impact of silencing U73166 on the viability of H1299 cells. A transwell invasion assay was performed to detect the invasive ability of H1299 cells. The Linc2GO database and a dual-luciferase reporter assay were used to predict and verify the binding site between U73166 and miR-618. Western blotting was used to analyze the relative expression of phosphorylated Janus kinase 2 (p-JAK2), phosphorylated signal transducer and activator of transcription 3 (p-STAT3), and phosphorylated signal-transducing adaptor molecule 1 (p-STAM1) in the JAK2/STAT3 signaling pathway to evaluate the effects of silencing U73166 on this pathway in H1299 cells. Data were analyzed by an independent sample t test or one-way analysis of variance. Results:Analysis of the GEPIA database revealed that U73166 relative expression level in lung cancer tissues ( n=383) was significantly higher than that in normal tissues ( n=347) ( P<0.01). The overall survival of lung cancer patients with low U73166 expression [(245±2) months] was longer than that of patients with high U73166 expression [(167±2) months] ( P<0.05). The relative expression of U73166 were 7.81±0.99 in the control group and 1.01±0.26 in the transfection group, respectively, and the relative expression of miR-618 were 1.03±0.20 in the control group and 4.83±1.27 in the transfection group, respectively. Silencing U73166 significantly downregulated its expression ( t=6.66, P<0.01) and upregulated the relative expression of miR-618 ( t=2.96, P<0.01) in H1299 cells. After silencing U73166, the absorbance values of H1299 cells in the transfection group on days 2, 3, 4, and 5 (0.36±0.04, 0.74±0.05, 1.07±0.09, and 1.18±0.10) were significantly lower than those in the control group (0.55±0.03, 1.20±0.08, 1.63±0.07, and 1.90±0.07) ( P<0.05, 0.01). The number of invasive cells in the control and transfection groups were 52.03±6.08 and 19.92±3.78, respectively. There were significantly fewer invasive cells in the transfection group ( t=4.49, P<0.01). After transfection with wild-type U73166, the relative luciferase activity in the miR-618 group (0.32±0.05) was significantly lower than that in the miR-negtive control group (0.96±0.15) ( t=4.02, P<0.01). However, after transfection with mutant U73166, there was no statistically significant difference in relative luciferase activity between the miR-618 group (1.01±0.15) and the miR-negtive control group (1.03±0.11) ( t=0.09, P>0.05). The relative expression of p-JAK2, p-STAT3, and p-STAM1 proteins in the transfection group were 2.08±0.21, 1.36±0.20, and 0.55±0.12, respectively. These values were significantly lower than those in the control group (3.72?±?0.29, 5.56?±?0.19, and 4.38±0.17) (all P<0.01). Conclusions:U73166 is highly expressed in lung cancer tissues and lung cancer cells, and its expression is related to lung cancer patients′ overall survival. Silencing U73166 can target miR-618, which inhibits the proliferation and invasion of H1299 cells.

Objective:To explore the safety and efficacy of intrasaccular flow disruptor in intracranial aneurysms, including wide-necked aneurysms.Methods:A retrospective analysis was performed; 102 patients with intracranial aneurysms treated with intrasaccular flow disruptor at Department of Neurointervention, First Affiliated Hospital of Zhengzhou University from August 2022 to November 2024 were enrolled; their clinical and imaging data were collected. The aneurysm characteristics and perioperative complications were summarized; aneurysm occlusion was evaluated by Woven EndoBridge occlusion scale (WOS) immediately after surgery and during the follow-up period.Results:Among the 102 aneurysms, 33 were anterior cerebral artery aneurysms, 40 were middle cerebral artery aneurysms, 17 were internal carotid artery aneurysms and 12 were basilar artery aneurysms; 73 aneurysms were regular intracranial saccular aneurysms and 29 were irregular saccular ones (17 of them with daughter sacs); 12 aneurysms were ruptured at acute phase. The surgical success rate was 100%: single intrasaccular flow disruptor was implanted into 95 patients, and stent-assisted or salvage treatments were given to 7 patients). Immediately after surgery, WOS grading A was noted in 5 patients, grading B in 7, grading C in 31, and grading D in 59. Two patients suffered severe perioperative complications and passed away: one patient died for ischemic complications that ensued after stent salvage treatment (parent artery being compressed by intrasaccular flow disruptor); the other patient died for hemorrhagic complications triggered by rupture of an initially unruptured aneurysm following intrasaccular flow disruptor implantation. Among them, 52 patients completed postoperative DSA follow-up, with a median follow-up of 205 (168, 292) days; WOS grading A was noted in 31 patients, grading B in 9, grading C in 8, and grading D in 4 at the last follow-up; the full occlusion rate was 92.3%, and no ischemic or hemorrhagic adverse events occurred.Conclusion:Intrasaccular flow disruptor shows high short-term safety and good efficacy in the treatment of intracranial aneurysms.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Objective:To investigate the treatment regimens, therapeutic effects, and adverse events of immune checkpoint inhibitors (ICI) in the treatment of progressive multifocal leukoencephalopathy (PML).Methods:A retrospective analysis was performed on patients with PML who received ICI treatment at the Department of Neurology of Peking Union Medical College Hospital from October 2020 to September 2024. The patients′ demographic characteristics, baseline immune status, clinical manifestations, laboratory tests, treatment regimens, and clinical outcomes were analyzed.Results:A total of 2 male patients with PML, aged 40 and 59 years, received ICI treatment. One patient had underlying combined immunodeficiency, while the other had acute myeloid leukemia subtype M2 and had previously undergone umbilical cord blood stem cell transplantation. Both patients were treated with pembrolizumab (dosage range: 2-3 mg/kg, administered every 3-4 weeks), receiving a total of 2-4 courses of treatment. In terms of therapeutic effects, both patients showed significant improvement. Regarding adverse events, 1 patient experienced immune-related adverse event (irAE) of immune-related pneumonia combined with immune-related hypophysitis.Conclusions:ICI may be an effective treatment option for PML. However, the use of ICI may be accompanied by the occurrence of irAE, necessitating close monitoring during treatment.
