Abstract
Secondary brain injury (SBI) is a noticeable contributor to the high mortality and morbidity rates associated with intracerebral hemorrhage (ICH), and effective treatment options remain limited. Cystatin C (CysC) emerges as a novel candidate for SBI intervention. The therapeutic effects and underlying mechanisms of CysC in mitigating SBI following ICH were explored in the current research. An in vivo ICH rat model was established by injecting autologous blood into the right caudate nucleus. Western blotting (WB) was utilized to assess the levels of CysC, cathepsin B (CTSB), and the NLRP3 inflammasome. Subsequently, the ICH rat model was treated with exogenous CysC supplementation or CysC knockdown plasmids. Various parameters, including Evans blue (EB) extravasation, brain water content, and neurological function in rats, were examined. RT-qPCR and WB were employed to determine the expression levels of CTSB and the NLRP3 inflammasome. The co-expression of CTSB, CysC, and NLRP3 inflammasome with GFAP, NeuN, and Iba1 was assessed through double-labeled immunofluorescence. The interaction between CysC and CTSB was investigated using double-labeled immunofluorescence and co-immunoprecipitation. The findings revealed an elevation of CysC expression level, particularly at 24 h after ICH. Exogenous CysC supplementation alleviated severe brain edema, neurological deficit scores, and EB extravasation induced by ICH. Conversely, CysC knockdown produced opposite effects. The expression levels of CTSB and the NLRP3 inflammasome were significantly risen following ICH, and exogenous CysC supplement attenuated their expression levels. Double-labeled immunofluorescence illustrated that CysC, CTSB, and the NLRP3 inflammasome were predominantly expressed in microglial cells, and the interaction between CysC and CTSB was evidenced. CysC exhibited potential in ameliorating SBI following ICH via effectively suppressing the activation of the NLRP3 inflammasome mediated by CTSB specifically in microglial cells. These findings underscore the prospective therapeutic efficacy of CysC in the treatment of ICH-induced complications.

Abstract
BACKGROUND Neoadjuvant chemoimmunotherapy is an important therapeutic modality for resectable nonsmall cell lung cancer (NSCLC). The roles of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio in predicting the efficacy and prognosis of patients with resectable NSCLC receiving neoadjuvant chemoimmunotherapy remain uncertain. This study aimed to explore the association of baseline and preoperative NLR, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio with the treatment response and survival of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy. MATERIALS AND METHODS Data of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy between May 2019 and July 2022 at our institute, were retrospectively analyzed. Peripheral blood cell counts were obtained at baseline and before surgery. Data that may affect treatment efficacy were also collected and analyzed, including age, sex, BMI, cumulative smoking exposure, pathological type, clinical stage, PD-L1 tumor proportion score, immune checkpoint inhibitors, dosage of neoadjuvant therapy, duration from final therapy to surgery, and baseline and preoperative oncological markers. The present work has been reported in compliance with REporting recommendations for tumor MARKer prognostic studies (REMARK) criteria and guidelines (Supplemental Digital Content 1, http://links.lww.com/JS9/A860 ). RESULTS A total of 116 patients were included in the study. Univariate logistic regression analysis showed that a higher baseline NLR ( P =0.001) and preoperative NLR ( P =0.001) were associated with a lower incidence of pathological complete response (pCR) following neoadjuvant therapy. Multivariate analysis indicated that a lower incidence of pCR was achieved in the high baseline NLR group ( P =0.014). Higher baseline NLR ( P =0.021), preoperative NLR ( P =0.004) and higher preoperative CEA levels ( P =0.059) were associated with shorter disease-free survival (DFS). Multivariate Cox proportional hazard regression analyses showed that shorter DFS was achieved in the high preoperative NLR group ( P =0.033). CONCLUSION In patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy, a higher baseline NLR was associated with a lower incidence of pCR, and a higher preoperative NLR was associated with a shorter DFS. However, a future prospective study with a large sample size and long-term follow-up is needed to verify the predictive value of NLR in these patients.

Abstract
The extraction of potassium from polyhalite ore (K2SO4·MgSO4·2CaSO4·2H2O) can help alleviate potassium resource shortages in China. In this study, the leaching behavior of potassium extracted from polyhalite ore in water was investigated using leaching experiments and kinetic analysis. The effects of various factors, such as liquid-to-solid ratio, leaching temperature, leaching time, and polyhalite ore particle size were comprehensively studied. It was found that high temperatures improved the reaction rate and efficiency at the beginning (1-15 min) but reduced the final leaching efficiency of potassium. And this phenomenon is discussed from the aspects of the dissolution-reprecipitation of potassium, newly formed solid products during the leaching process, and leaching thermodynamics. The leaching of potassium followed the Avrami model, with an apparent activation energy of 26.29 kJ/mol. Additionally, it was determined that the mixed controlled step (surface chemical reaction and diffusion) was the controlling step during potassium leaching. This study clarified the leaching mechanism of the polyhalite in water, and the causes of hindering the leaching of potassium were analyzed. The research results can provide theoretical reference and solutions for parameter design for the enhanced leaching process and selection of leaching agents in the future.

Abstract
Accumulating evidence suggests that patients with pulmonary lymphangioleiomyomatosis (PLAM) have a markedly higher prevalence of breast cancer (BC) than the general population. However, the underlying pathophysiological mechanisms remain unclear. Therefore, in this study, we employed a bioinformatics approach to understand the association between PLAM and estrogen receptor (ER)-positive BC. The PLAM (GSE12027) and ER-positive BC (GSE42568, GSE29044, and GSE29431) datasets were obtained from the Gene Expression Omnibus database, and GEO2R was used to identify common differentially expressed genes (DEGs) between them. Functional annotation was performed, and a protein-protein interaction (PPI) network was constructed. Hub genes were identified and verified using western blotting and immunohistochemistry. We conducted an immune infiltration analysis; based on the results, selected 102 common DEGs for follow-up analysis. Functional analyses revealed that the DEGs were mostly enriched in cell proliferation, gene expression regulation, and tumor-related pathways. Four hub genes-ESR1, IL6, PLA2G4A, and CAV1-were further analyzed, and CAV1 was revealed to be associated with clinical outcomes and immune infiltration in ER-positive BC. This study proposes a common, possible pathogenesis of PLAM and ER-positive BC. These common pathways and pivotal genes may provide new directions for further mechanistic studies.

Abstract
One mode by which infection-derived immunity fails is when recovery leads to a reduced but nonzero risk of reinfection. This type of partial protection is called leaky immunity with the degree of leakiness quantified by the relative probability a previously infected individual will get infected upon exposure compared to a naively susceptible individual. Previous authors have defined the reinfection threshold, which occurs when the basic reproduction number equals the inverse of the leakiness, however, there has been some debate about whether or not this is a real threshold. Here we show how the reinfection threshold relates to two important occurrences: (1) the point at which the endemic equilibrium changes from being a stable spiral to a stable node, and (2) the point at which the rate of change of the prevalence increases the most relative to leakiness. When the recovery period is short relative to the average lifetime then both occurrences are close to the reinfection threshold. We show how these results are related to the reinfection threshold found in other models of imperfect immunity. To further demonstrate the significance of this threshold in modeling, we conducted a simulation study to evaluate some of the consequences the reinfection threshold might have in parameter estimation and modeling. Using specific parameter values chosen to reflect an acute infection, we found that the basic reproduction number values larger than that of the reinfection threshold value were less identifiable than those below the threshold.

Abstract
The aim of this study was to evaluate the biomarker potential of TIMP-2 in septic-induced acute kidney injury (AKI). Healthy male rats (n=56, age 8-10 weeks, body weight 250-300 g) were randomized into 3 groups: controls (intact rats, n=6), sham-operated (SO, n=24), and sepsis model (cecum ligation and perforation, CLP, n=24). Thirty minutes before and 6, 12, 24, and 48 h after surgery, blood samples were collected to measure serum creatinine, blood urea nitrogen (BUN), and TIMP-2 and the kidneys were isolated for histopathological analysis and Western blotting. The key sepsis-related genes were screened through bioinformatics analysis. In 24 and 48 h after surgery, 2 rats in the SO group reached the diagnostic criteria of AKI (increased levels of serum creatinine and BUN). In the CLP group, serum creatinine in 6 h after the surgery was slightly higher than 30 min before the surgery, but this change did not meet the diagnostic criteria for AKI. In the CLP group, BUN was normal 6 h after the surgery, but increased after 12 h. In more than 50% rats of the CLP group, serum creatinine and BUN significantly increased 12 h after operation, so this can be diagnosed as AKI. In rats of the CLP group, plasma TIMP-2 was elevated 6 h after surgery and increased with time, suggesting that plasma TIMP-2 can be used as an early marker of AKI. Histological examination of the kidneys in this group revealed destruction of the renal tubular structure, swelling of renal tubular epithelium, the disappearance of brush edge and collapse of necrotic epithelial cells, etc., and the degree of damage increased with time. Immunohistochemistry showed that TIMP-2 was expressed in rats of the CLP group at all terms of the experiment. The expression of TIMP-2 and pyroptosis-related proteins (NLRP3, IL-1β, caspase-1, and GSDMD) in the CLP group was higher than in the SO group (p<0.05) and increased with time, suggesting that pyroptosis is involved in AKI. Thus, plasma TIMP-2 is sensitive indicator for the early detection of kidney injury and can be used as an early biomarker of AKI.

Abstract
Objective The prognostic role of perineural invasion (PNI) in resected non-small cell lung cancer (NSCLC) remains unclear. A meta-analysis was performed to compare the overall survival (OS) of patients with resected NSCLC with and without PNI. Methods The PubMed, EMBASE, and Web of Science databases were systematically searched to identify relevant studies investigating the effect of PNI on OS in patients with resected NSCLC. Pooled hazard ratio (HR) and 95% confidence intervals (CI) were estimated using a random-effects model. Separate meta-analyses using adjusted or unadjusted HR for OS were performed using Stata/SE 12.0. Results Eleven studies comprising 2,279 patients were included. In total, PNI was identified in 9% (median, 4%-31%) of patients with resected NSCLC. The unadjusted pooled effect of the PNI was significantly associated with worse OS (HR, 2; 95% CI, 1.65-2.43). Adjusting for potential confounders yielded a similar result, with OS being significantly worse (HR, 2.13; 95% CI, 1.8-2.51) for patients exhibiting PNI. Conclusion This meta-analysis indicates that the PNI is a strong prognostic factor for unfavorable outcomes in patients with resected NSCLC. Further large-scale prospective lung cancer trials are required to validate these results.

Abstract
OBJECTIVE The objective of this study is to study the mechanism of Low frequency electrical stimulation (LFS) in the treatment of drug-resistant epilepsy by regulating the protein kinase A (PKA)-cAMP response element-binding protein (CREB) signaling pathway upstream of gamma aminobutyric acid A (GABAA) receptor. METHODS Primary hippocampal neurons were extracted and cultured from fetal rat brains and randomly divided into the normal control group, PKA-CREB agonist group, and PKA-CREB inhibitor group. Drug-resistant epileptic rats were established and randomly divided into the pharmacoresistant group, LFS group, PKA-CREB agonist combined with hippocampal LFS group, and PKA-CREB inhibitor combined with hippocampal LFS group. The normal rats were in the normal control group and drug-sensitive rats were in the pharmacosensitive group. The seizure frequency of epileptic rats was determined using video surveillance. The expression of PKA, CREB, p-CREB, and GABAA receptor subunits α1 and β2 of each group were detected using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting assays. RESULTS The in vitro expression levels of PKA, CREB, and p-CREB in the agonist group were significantly higher than those in the normal control group (NRC group), while the expression levels of GABAA receptor subunits α1 and β2 were significantly lower than those in the NRC group. The expression levels of PKA, CREB, and p-CREB in the inhibitor group were significantly lower, while the expression levels of GABAA receptor subunits α1 and β2 were significantly higher than those in the NRC group. The in vivo seizure frequency was significantly lower in the LFS group than in the pharmacoresistant group (PRE group). Compared to the LFS group, the seizure frequency and the expression levels of PKA, CREB, and p-CREB in the rat hippocampus were significantly higher, and the expression levels of GABAA receptor subunits α1 and β2 were significantly lower in the agonist group. The results in the inhibitor group were exactly the opposite of those in the agonist group. CONCLUSION The PKA-CREB signaling pathway is involved in the regulation of GABAA receptor subunits α1 and β2. In addition, LFS plays an important role in increasing GABAA receptor expression by regulating the PKA-CREB signaling pathway.

Abstract
BACKGROUND Pulmonary sequestration (PS) is a rare congenital lower airway malformation. This study presents the clinical and imaging features and surgical outcomes of PS in adults, and compare the safety and feasibility of minimally invasive surgery versus open thoracotomy for PS. METHODS Adult patients with PS treated at our center from July 2011 to September 2021 were included. Information regarding the patient demographics, clinical and CT features, arterial supply and venous drainage, and surgical outcomes were collected. RESULTS Ninety seven patients were included. The most common CT findings were mass lesions (50.5%) and cystic lesions (20.6%). The vast majority of the lesions (96 out of 97) were located close to the spine in the lower lobes (left vs. right: 3.6 vs. 1). Arterial supply was mainly provided by the thoracic aorta (87.4%) and abdominal aorta (10.5%). Intralobar and extralobar PS accounted for 90.7% and 9.3% of the patients, respectively. Three (4.5%) patients who underwent minimally invasive surgery were converted to open thoracotomy due to dense adhesions. Though no significant differences regarding operative time (P = 0.133), the minimally invasive surgery group was significantly better than the open thoracotomy group regarding intraoperative blood loss (P = 0.001), drainage volume (P = 0.004), postoperative hospital days (P = 0.017) and duration of chest drainage (P = 0.001). There were no cases of perioperative mortality. Only four (4.1%) patients developed postoperative complications, and no significant difference existed between the two groups. CONCLUSION Our study revealed PS can present with a variety of different clinical and radiologic manifestations. Clinicians should consider the possibility of PS when diagnosing a lesion in the lower lobes close to the spine. Moreover, minimally invasive surgery is a safe and effective treatment modality for the treatment of PS in an experienced center.

Abstract
BACKGROUND PPARγ has been reported to participate in intracerebral hemorrhage (ICH) progression, and recruit RAD21 through binding DNA. Our study aimed to explore the roles of PPARγ/RAD21 in ICH and their related mechanisms. METHODS ICH models in vitro and in vivo were established using thrombin and autologous blood injection, respectively. After that, rosiglitazone (RSG), GW9662, and RAD21 knockdown/overexpression plasmids were used to treat the ICH models. The cell apoptosis, the related inflammatory cytokines levels, and the neurological function of the rats were examined. Real-time quantitative PCR (RT-qPCR), western blot and immunofluorescence were employed to determine the expression of the M1/M2 polarization-related markers. Finally, the interaction of PPARγ and RAD21 in microglial cells was observed using double labeled immunofluorescence and co-immunoprecipitation. RESULTS After thrombin induction, the cell apoptosis, and TNF-α, IL-1β and IL-10 contents were all significantly increased (P < 0.05); whereas RSG and RAD21 overexpression evidently inhibited the apoptosis of thrombin-caused microglial cells, reduced TNF-α and IL-1β contents, further increased IL-10 content (P < 0.05). The combination of RAD21 and PPARγ was enhanced by RSG and RAD21 overexpression. In vivo experiments showed that RSG and RAD21 overexpression decreased neurological deficit score, brain water content and hematoma volume. Additionally, RSG and RAD21 overexpression up-regulated the expression of PPARγ, RAD21, Arg1, KLF4, and TGF-β, whereas down-regulated iNOS and CD32 expression. The actions of GW9662 and RAD21 knockdown were opposite to those of RSG and RAD21 overexpression. CONCLUSION PPARγ/RAD21 may alleviate ICH progression through promoting M2-type polarization of microglial cells and inhibiting inflammatory response.

Abstract
Objective The present study aimed to evaluate the clinical value of minimally invasive surgery for intracranial hematoma removal and high intracranial pressure (ICP) reduction using a novel three-needle brain puncture technique. Methods A total of 202 cases with supratentorial hematoma were analyzed, 54 of whom received three-needle brain puncture (study group), and the remaining cases received single-needle (control groups 1 and 2) and two-needle brain puncture (control group 3). The amount of intracranial hematoma removed, changes in ICP, retention time of puncture needle, volume of residual blood, the National Institute of Health Stroke Scale (NIHSS) score, and postoperative survival rate were used as indexes to evaluate patient outcomes. Results We found that three-needle brain puncture (study group) can remove more intracranial hematoma (P < 0.05) and achieve lower ICP (P < 0.05) than single- and two-needle brain puncture (control group). The needle retention time and volume of residual blood significantly decreased in the study group. Additionally, a statistically significant difference was observed in the NIHSS scores and survival rates between the study and control groups (P < 0.05). Conclusion These data suggest that three-needle minimally invasive stereotactic puncture can effectively remove hematoma, reduce ICP, decrease the degree of brain damage, and improve prognosis.

Abstract
We explored the association between the serum level of cystatin C (CysC) at admission and short-term functional outcome in patients with hypertensive intracerebral hemorrhage (HICH) without chronic kidney disease (CKD). A total of 555 patients with HICH were consecutively recruited after admission and were followed-up for 3 months after admission. The primary outcome was poor functional outcome (modified Rankin Scale [mRS] score ≥ 3). The median serum CysC level in our cohort was 1.03 mg/L (interquartile range, .89-1.20). Patients were categorized into four groups according to the serum CysC quartiles. Multivariate logistic regression analysis revealed a negative association between serum CysC and poor functional outcome at 3-month follow-up (quartile [Q]1 vs. Q4: adjusted odds ratio [OR] = .260, 95% confidence interval [CI] = .098, .691, p < .001). The negative association between serum CysC and poor functional outcome at 3 months was more pronounced in subgroups with smaller hematoma volume (≤ 30 mL), and absence of secondary intraventricular hemorrhage (IVH). Addition of serum CysC to a model containing conventional risk factors improved the model performance with net reclassification index (NRI) of .426% (p < .001) and integrated discrimination improvement (IDI) of .043% (p < .001) for poor functional outcome. Serum CysC was found to be a negative predictor of poor short-term functional outcome in HICH patients independent of renal function.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is one of the most malignant cancer types, characterized by a poor prognosis. N6-methyladenosine (m6A) is a prevalent internal modification of mRNA. METTL14, an RNA methyltransferase that mediates m6A modification, is implicated in mRNA biogenesis. However, the biomechanism of METTL14 in NSCLC is not very clear. METHODS Here, immunohistochemical (IHC) assay was employed to detect METTL14 in NSCLC tissues. The biological functions of METTL14 were demonstrated using cell transfection, cell proliferation assay, cell clone formation assay, cell cycle analysis, cell death analysis, transwell and wound healing assays. Transcriptome and methylated RNA immunoprecipitation (MERIP)-sequencing were used to explore the pathways and potential mechanism of METTL14 in NSCLC. RNA sequencing, METTL14 rip-sequencing, and METTL14 merip-sequencing were conducted to identify the potential targets of METTL14. RESULTS METTL14 was significantly correlated with clinical pathological parameters of differentiation and M stage. Additionally, METTL14 promotes cell proliferation, induces cell death, and enhances cell migration and invasion in vitro. Transcriptome and MeRIP-sequencing reveal oncogenic mechanism of METTL14. RIP-sequencing highlights CSF1R and AKR1C1 as targets of METTL14. After validation with TCGA dataset, colony stimulating factor 1 receptor (CSF1R) showed significant positive coefficient with METTL14, and was presumed to be one target of METTl14 in lung cancer and verified by the cellular experiments. CONCLUSION In conclusion, our results revealed the clinical significance of m6A RNA modification atlas, the function, and molecular targets CSF1R of METTL14 in NSCLC cell lines. The RNA m6A methyltransferase METTL14 promotes the progression of NSCLC by targeted CSF1R.

Abstract
Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) targeted therapy has become the standard of care for patients with EGFR-mutated metastatic non-small cell lung cancer (NSCLC) on the basis of improved prognosis and reduced toxicities compared with chemotherapy. In view of the therapeutic potential of EGFR-TKIs in EGFR-mutated advanced NSCLC, several scholars have explored the value of preoperative use of EGFR-TKIs in patients with EGFR-mutated resectable NSCLC. However, the field of neoadjuvant targeted therapy for EGFR-mutated resectable NSCLC is currently in its infancy. In this mini-review, we summarize the current evidence on neoadjuvant EGFR-TKIs targeted therapy for resectable EGFR-mutated NSCLC and focus on discussing potential clinical strategies of treating resectable EGFR-mutated patients by preoperative administration of EGFR-TKIs-based multimodality therapy.

Abstract
Intracerebral hemorrhage (ICH) is a devastating form of stroke with high rates of morbidity, mortality, and disability. It induces cell death that is responsible for the secondary brain injury (SBI). The underlying mechanism of SBI after ICH is still unclear, and whether it is related to iron overload is worthy to be discussed. Ferroptosis is an iron-dependent non-apoptotic modes of cell death and plays a particularly important role in the occurrence and progression of ICH. Many ICH-induced regulators and signalling pathways of ferroptosis have been reported as promising targets for treating ICH. In this article, we review the definition, characteristics, and inhibition methods of neuronal ferroptosis caused by iron deposition after ICH, and review the biomarkers for ferroptosis.

Abstract
Background: Alectinib, a highly selective inhibitor of ALK, is currently used in the first-line setting of untreated advanced ALK-positive NSCLC and in the second-line setting of crizotinib-resistant ALK-positive NSCLC. Despite promising efficacy and tolerability in the treatment of advanced ALK-positive NSCLC, the activity of alectinib as neoadjuvant therapy in resectable ALK-positive NSCLC remains to be investigated. Case presentation: Herein, we report a case of a 58-year-old female patient presented to our hospital with hemoptysis for 1 month. Contrast-enhanced computerized tomography (CT) of the chest showed an approximately 4.2 × 3.4 cm mass in the right hilum with localized obstructive pneumonia in the right lower lobe and multiple enlarged lymph nodes in the right hilum and mediastinum. Serum oncological markers results showed elevated levels of CA19-9, CEA, CA125, and CA242. Bronchoscopic biopsy of the mass showed poorly differentiated pulmonary adenocarcinoma and immunohistochemical testing results confirmed ALK positivity. Neoadjuvant alectinib was given at a dosage of 600 mg twice per day for two cycles (56 days), achieving a partial response of the disease with 90% shrinkage of the mass at the subsequent whole-body positron emission tomography. Repeat serum oncological markers results showed that only CA125 was elevated, but lower than before therapy. A bilobectomy of the right middle and lower lobes and systemic lymphadectomy under video-assisted thoracoscopic approach was successfully performed 7 days after the last dose of alectinib. Postoperative pathology showed pathological complete response (pCR). The patient experienced an uneventful postoperative course and continued to receive alectinib and did not report any specific discomfort at her 8-month follow-up. Thoracoabdominal CT at 8 months postoperatively showed no recurrence and repeated examination of serum oncological markers were negative. Conclusion: We report a case of resectable ALK-positive NSCLC treated with neoadjuvant aletinib achieving pCR. Our case highlights the feasibility of alectinib as neoadjuvant therapy for the treatment of resectable ALK-positive NSCLC. Undoubtedly, the safety and efficacy of this novel treatment modality needs to be explored in future large clinical trials.

Abstract
The final velocity was put forward to study the water flow characteristics inside the building drainage system; however, it is more suitable for low-rise and multi-storey buildings, not for high-rise buildings. This study revealed the drainage transient characteristics of a double stack drainage system in high-rise residential buildings. Based on the final velocity, the air-water interaction mechanism and two-phase flow conditions in high-rise residential drainage stacks were discussed. An influence model of drainage system flow rate on pressure fluctuation under the change of state parameters such as ventilation rate, pipe wall roughness and building height was established. The pressure limit and flow rate data were obtained through full-scale experiments. The pressure limit and flow rate model were simplified to Pn = A ċ Q2 + B ċ Q1:81 + C. After the data were verified, the fitting coefficients A, B and C were linear to the floor height.

Abstract
Background: Evidence of osimertinib as neoadjuvant therapy for resectable non-small cell lung cancer (NSCLC) are currently lacking. This case series study aimed to assess the safety and feasibility of neoadjuvant osimertinib therapy followed by surgery for resectable NSCLC.Materials and methods: Patients with resectable NSCLC with epidermal growth factor receptor (EGFR) mutation who received osimertinib as neoadjuvant therapy followed by surgery at our center were included. Demographic features, radiologic and pathological assessment of response, surgery-related details and complications, toxicity profiles, and prognostic outcomes were extracted.Results: A total of 13 patients were included in this study. The median age at the time of surgical resection was 57 years (interquartile range: 52–64 years), and eight (61.5%) patients were female. The objective response rate (ORR) was 69.2% (9/13), and the complete resection rate was 100%. The rates of pathologic downstaging and lymph node downstaging were 100% (13/13) and 66.7% (6/9), respectively. There were no perioperative deaths and only three (23.1%) patients had postoperative complications. Seven (53.8%) and 13 (100%) patients experienced grade 1 treatment-related adverse reactions and laboratory abnormalities, respectively. No patients experienced drug withdrawal or surgical delays due to the adverse events. No patients showed grade 2 or worse toxicity profiles. One patient was lost to follow-up. The other 12 patients were alive and free of disease recurrence with a median follow-up time of 9.5 months.Conclusion: Neoadjuvant osimertinib therapy seemed to be safe and feasible for resectable EGFR-mutated NSCLC. Future large prospective studies are warranted to confirm whether osimertinib as neoadjuvant therapy outperforms standard tyrosine kinase inhibitors (TKIs) or chemotherapy for resectable EGFR-mutated NSCLC.

Abstract
Methionine is an essential amino acid involved in many physiological and pathological processes. Methionine starvation caused by methionine decarboxylase ( MetDC) degradation becomes a promising strategy for cancer treatment. Multistep colorimetric method, the present approach to monitor the MetDC activity, possesses drawbacks of the complicated process, low accuracy, and poor anti-interference due to indirect detecting. Herein, we report a facile and easy-to-use supramolecular tandem assay (STA) with cucurbit[7]uril and acridine orange reporter pair for the direct and real-time monitoring of MetDC activity. The applicability of this strategy for measuring enzyme-kinetic parameters and screening of inhibitors are also demonstrated. The STA for MetDC activity detection not only provides a feasible method for methionine-related disease diagnosing but also opens a perspective for cancer therapy.

Abstract
Background and PurposeMinimally invasive surgery (MIS) is performed to treat patients with intracerebral hemorrhage (ICH) with favorable results. However, postoperative rehemorrhage is a significant risk. The present study retrospectively analyzed the association of irregular-shaped hematoma with postoperative rehemorrhage following stereotactic MIS (sMIS).MethodsWe enrolled 548 patients with spontaneous ICH who underwent sMIS. Based on the hematoma shape, the patients were assigned to the regular-shaped hematoma group (RSH group; 300 patients) or irregular-shaped hematoma group (ISH group; 248 patients). Logistic regression analysis was performed to identify the predictors of postoperative rehemorrhage after sMIS for ICH evacuation. The functional outcome was assessed using the modified ranking scale (mRS) score at discharge. A receiver operating characteristic (ROC) curve was used to confirm the results.ResultsAmong 548 patients with ICH who underwent sMIS, 116 developed postoperative rehemorrhage. Postoperative rehemorrhage occurred in 30.65% of patients with ISH and 13.30% with RSH (P < 0.01), with a significant difference between the ISH and RSH groups. Among 116 patients with postoperative rehemorrhage, 76 (65.52%) showed ISH on CT scan. In 432 patients without postoperative rehemorrhage, only 39.81% displayed ISH. The logistic regression analysis demonstrated that ISH could independently predict postoperative rehemorrhage. The sensitivity, specificity, positive predictive value, and negative predicative value were 0.655, 0.398, 0.655, and 0.602, respectively. The ROC analysis confirmed the value of ISH in predicting postoperative rehemorrhage with an area under the curve of 0.629.ConclusionsIrregular-shaped hematoma was an independent predictor of postoperative rehemorrhage after sMIS.

Abstract
ObjectiveTo investigate the role of minimally invasive surgery (MIS) in intracerebral hemorrhage (ICH) evacuation combined with deferoxamine (DFX) treatment on perihematomal tight junction protein (claudin-5 and ZO-1) expression levels and blood-brain barrier (BBB) permeability in rabbits.MethodsWe randomly assigned 65 male rabbits (weight: 1.9–2.6 kg) to a normal control group (NC group, 13 rabbits), hemorrhage model group (HM group, 13), DFX treatment group (DFX group, 13 rabbits), MIS group (MIS group, 13 rabbits), or MIS combined with DFX treatment group (MIS + DFX group, 13 rabbits). ICH was established in all of the groups except the NC group. MIS was performed to evacuate the hematoma 6 h after the ICH model was created in the MIS and MIS + DFX groups. The DFX and MIS + DFX groups were treated with DFX (100 mg/kg, dissolved in 2 mL of 0.9% saline solution, administered intramuscularly) at 2 h, and then every 12 h for 7 d. The same dose of 0.9% saline solution was administered to the NC, HM, and MIS groups at the same time points. Sixty-five rabbits were divided into 5 groups, and 13 rabbits in each group. Neurological deficit (i.e., Purdy's score) was recorded in all rabbits before euthanasia (N total = 65). In each group, 2 rabbits were used for iron concentration measurement (N total = 10), 2 rabbits were used for brain water content measurement (N total = 10), 3 rabbits were used for BBB permeability measurement (N total = 15), 3 rabbits were used for claudin-5, ZO-1 expression detection by Western Blotting (N total = 15), and 3 rabbits were used for claudin-5, ZO-1 mRNA detection by real-time PCR (N total = 15). On day 7, the rabbits were sacrificed and the perihematomal brain tissue was harvested to test the iron concentration, brain water content (BWC), tight junction proteins (claudin-5 and ZO-1) expression, and BBB permeability.ResultsPurdy's score, iron concentration, and BWC were lower in the MIS and MIS + DFX groups compared to the HM and DFX groups. The MIS + DFX group showed a significant decrease in these indicators. The use of MIS to evacuate the hematoma led to increased expression levels of claudin-5 and ZO-1, as well as decreased BBB permeability. The MIS + DFX group exhibited a remarkable increase in claudin-5 and ZO-1 expression levels and a significant decrease in BBB permeability.ConclusionsMIS combined with DFX treatment could increase the expression levels of perihematomal tight junction proteins (claudin-5 and ZO-1) expression, reduce BBB permeability, and improve the neurological function. MIS combined with DFX treatment may also prevent secondary brain damage following ICH.

Abstract
Surgical resection is currently the mainstay of treatment for tracheobronchial mucoepidermoid carcinoma (TMEC). The parenchymal sparing secondary carinal resection and reconstruction for TMEC under the uniportal thoracoscopic approach has seldomly been reported in the literature. Here, we report a case of a 42-year-old male patient complaining of the incidental finding of a 1.5 × 1.2 cm neoplasm at the opening of the right bronchus intermedius and a 5.1 × 3.1 cm patchy lesion located at the left upper lobe by chest CT scans in February 2021. This patient successively underwent fiberoptic bronchoscopic biopsy of the bronchial neoplasm and CT-guided biopsy of the left upper lobe lesion. Pathological examination confirmed the diagnosis of the endobronchial mass in the right bronchus intermedius as low-grade mucoepidermoid carcinoma and left upper lobe lesion as tuberculosis. This patient successfully underwent uniportal thoracoscopic parenchymal sparing tumor resection, reconstruction of the secondary carina and lymphadenectomy at our center. Intraoperative frozen section showed no residual cancer at any bronchial stumps. Postoperative pathology indicated that no metastases were seen in any of the resected lymph nodes. The patient recovered well after surgery. He received a 9-month course of anti-tuberculosis treatment postoperatively. He did not complain of any special discomfort and there was no local recurrence at the 9-month postoperative follow-up. Although technical demanding, this case highlights that uniportal video-assisted thoracoscopic parenchymal sparing secondary carinal resection and reconstruction for TMEC is safe and feasible with the preservation of lung function and excellent outcomes.

Abstract
Data evaluating changes in bone mineral density (BMD) in Down syndrome (DS) individuals remains controversial. Therefore, we conducted a systematic review and meta-analysis to better understand associations between BMD and DS. A systematic literature search of PubMed, EMBASE, Web of Science, and the Cochrane Library up until 1st January 2021 was conducted. We used the keywords "bone mineral density" and "Down Syndrome." Fifteen studies were included. Overall, our results showed a significant decrease in BMD of total body (TB BMD) [MD = - 0.18; 95% CI (- 0.23 and - 0.12), P < 0.00001, I2 = 89%], total hip (TH BMD) [MD = - 0.12; 95% CI (- 0.15 and - 0.10), P < 0.00001, I2 = 0%], lumbar spine (LS BMD) [MD = - 0.12; 95% CI (- 0.14 and - 0.09), P < 0.00001, I2 = 18%], and femoral neck (FN BMD) [MD = - 0.08; 95% CI (- 0.10 and - 0.06), P < 0.00001, I2 = 0%] in DS individuals when compared with controls. Moreover, the volumetric BMD of lumbar spine (LS vBMD) [MD = - 0.01; 95% CI (- 0.02 and - 0.01), P = 0.0004, I2 = 19%] also showed a decreasing tendency while the volumetric BMD of the femoral neck (FN vBMD) [MD = 0.01; 95% CI (0.00 and 0.02), P = 0.02, I2 = 0%] was elevated in DS individuals versus controls. These findings demonstrated that individuals with DS had a decreased total and regional (TH, LS, and FN) BMD when compared with the general population. Additionally, when BMD was adjusted for skeletal volume, LS vBMD was also lower, while FN vBMD was elevated in DS individuals versus controls.

Abstract
Left innominate vein aneurysm is extremely rare, with a limited number of case reports present in the literature. Herein, we report a case of a 50-year-old female patient presenting with an incidental finding of an anterior mediastinal mass on chest radiography during a routine health examination. Contrast-enhanced computerized tomography (CT) of the chest showed a 4.8 × 4.6 cm anterior mediastinal mass with significant homogenous enhancement after injection of the contrast medium, suggesting a diagnosis of Castleman's disease, but not excluding thymoma. The patient underwent surgical resection of the anterior mediastinal mass under a thoracoscopic approach. Postoperative pathology confirmed the diagnosis of a left innominate vein aneurysm. This is the first case reporting a left innominate vein aneurysm resected under thoracoscopy. Despite this successful treatment experience, we need to emphasize that open thoracotomy or median sternotomy should be chosen as the first choice for surgeons who lack experience in thoracoscopic surgery, with the aim of avoiding intraoperative accidents.

Abstract
Introduction/Objective
NTRK3 gene encodes a transmembrane protein receptor of the tropomyosin receptor kinase (Trk) family. Gene fusions involving NTRK3 result in a constitutive activation or overexpression of Trk receptor, potentially leading to oncogenesis. NTRK targeted therapies show a promising activity in varied cancer types with NTRK fusions. The aim of this case review is to describe the clinical and pathologic findings of thyroid neoplasm with NTRK3 gene fusions.

The cytology fine needle aspiration (FNA), molecular testing results and pathology of surgical resections are reviewed in 220 cases of total and hemithyroidectomy from January 2018 to May 2021.
Results (if a Case Study enter NA)
Three cases with NTRK3 gene fusions are identified by Thyroseq or Afirma GSC from FNA of thyroid nodules with later surgical intervention. No other mutations or gene fusions were identified. Each case had total thyroidectomy. Case 1 is a 41-year-old female with FNA diagnosis of suspicious for papillary thyroid carcinoma (PTC) and ETV6/NTRK3 fusion found by Afirma GSC. Pathology diagnosis is PTC classic type, two tumor nodules 1.1cm and 1.0cm, lymphovascular invasion not identified, three lymph nodes not involved by tumor and pathologic stage pT1b(m) pN0. Case 2 is a 49-year-old female with FNA diagnosis of atypia of undetermined significance and ETV6/NTRK3 fusion detected by Thyroseq. Pathology diagnosis is infiltrative PTC follicular variant, 2.0cm, angioinvasion present, no lymph nodes submitted and pathologic stage pT1b(m) pNX. Case 3 is a 28-year-old female with FNA diagnosis of suspicious for follicular derived neoplasm and NTRK3/RBPMS fusion is detected by Afirma GSC. Pathology diagnosis is infiltrative PTC follicular variant, 1.5cm, 9 of 11 lymph nodes positive for metastatic carcinoma and pathologic stage pT1b pN1b.
Conclusion
Thyroid neoplasm with NTRK3-rearrangement is rare. Cases 1 and 2 with common ETV6-NTRK3 fusion show PTC classic type and infiltrative PTC follicular variant with angioinvasion. Case 3 with less common NTRK3/RBPMS fusion shows infiltrative PTC follicular variant and significant lymph node involvement. Our limited cases of NTRK3-rearranged thyroid carcinoma demonstrate infiltrative growth, diverse phenotypes, one case with angioinvasion and no lymph nodes submitted and one case with multiple lymph node metastasis. This suggests aggressive behavior of thyroid cancer with NTRK3 gene fusion and patients may benefit from targeted NTRK therapy.

Abstract
Abstract
Introduction/Objective
Thyroid adenoma-associated (THADA)-IGF2BP3 fusions is related to strong overexpression of insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) mRNA and protein, increased IGF2 translation and IGF1 receptor signaling via PI3K and MAPK pathways. THADA-IGF2BP3 have been identified as an oncogenic event in thyroid neoplasms, but the clinicopathologic features have not been greatly evaluated. The purpose of this cases review is to describe the clinical and pathologic findings of thyroid nodules with THADA-IGF2BP3 fusion on molecular testing.
Methods/Case Report
Surgical Pathology 220 cases of total and hemithyroidectomy from January 2018 to December 2019 were reviewed for cytology fine needle aspiration (FNA), molecular testing results and surgical resection pathology.
Results (if a Case Study enter NA)
Three cases of THADA-IGF2BP3 fusion identified by Thyroseq testing from FNA of thyroid nodules with all diagnosed as atypia of undetermined significance, Bethesda category 3. No other mutations or gene fusions are identified. Successive surgical interventions are performed. Case 1 is a 49-year-old female right hemithyroidectomy with pathologic diagnosis of papillary thyroid carcinoma (PTC) follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, two lymph nodes evaluated are not involved by tumor and pathological stage is pT1b pN0. Case 2 is a 71-year-old female total thyroidectomy and the pathologic diagnosis is PTC follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, one lymph node evaluated is not involved by tumor and pathologic stage is pT1b pN0. Case 3 is a 76-year-old male left hemithyroidectomy and pathologic diagnosis is PTC follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, two lymph nodes evaluated are not involved by tumor and pathologic stage is pT1b pN0.
Conclusion
THADA-GF2BP3 fusion is uncommon in thyroid neoplasms and only three cases are detected in 220 cases evaluated. The three cases of thyroid nodules are all diagnosed as AUS by FNA, and all are diagnosed as PTC follicular variant with capsular invasion upon resection without lymphvascular invasion or lymph node involvement. THADA-F2BP3 fusion is associated with thyroid carcinoma, with low-risk non-aggressive behavior, conservative surgery appears necessary and lobectomy is likely adequate.

Abstract
Abstract
Introduction/Objective
Endometrial stromal sarcoma (ESS), a rare malignant neoplasm of endometrial stroma, accounts for less than 1% of all uterine tumors. High grade ESS (HGESS) is aggressive and commonly relapses even after surgical and neoadjuvant therapy. Abdominal and pelvic regions are common sites of metastasis, however, distant metastases to the liver, lung, vertebrae, and brain have been reported.
Methods/Case Report
We encountered a 49-year-old female who presented with shortness of breath, found to have a left pleural effusion and multiple pleural masses. She initially presented three years ago with heavy irregular menses and left pelvic pain for one year. D&C revealed prominent small spindle cells for which a stromal nodule and low-grade or malignant process was probable. CT scan showed an enlarged uterus. Hysterectomy with bilateral salpingo- oophorectomy, bilateral pelvic and para-aortic lymph node dissection, and partial omentectomy were performed. The uterus revealed an intramural 7 cm mass with a serpiginous growth pattern and lymphovascular invasion. Tumor cells were plump to spindled with areas of high cellularity, rounded nuclei, increased atypia and mitosis. Atypical areas were positive for cyclin D1, focally positive for CD10, and negative for ER, PR, SMA, desmin, AE1/3 and CAM5.2. FISH studies showed rearrangement of YWHAE gene (17p13.3) and no rearrangement of JAZF1 or PHF1 gene regions. Findings supported the diagnosis of HGESS. The patient received post-operative chemotherapy. Biopsy of the current pleural lesion revealed a nonspecific malignant spindle cell neoplasm positive for BCL1, CD56, CD117, CD99, TLE1 and INI1, while negative for AE1/3, CAM5.2, EMA, ER, PR, CK5/6, calretinin, SMA, desmin and S100. The CD10 stain was inconclusive. FISH studies showed rearrangement of YWHAE gene (17p13.3) and no rearrangement involving JAZF1 or PHF1 gene regions. No rearrangement of the SS18 gene region was observed and synovial sarcoma was excluded. Overall findings support the diagnosis of metastatic HGESS.
Results (if a Case Study enter NA)
NA
Conclusion
HGESS, a rare tumor with a nonspecific immunostain profile, has the ability to metastasize to rare body sites, such as the pleura in our case. Display of spindle cell morphology is a nonspecific finding that raises broad differential diagnoses. In women, with or without a history of uterine neoplasm, HGESS is a clinically worthwhile diagnosis to be mindful of.

Abstract
BACKGROUND The mossy fiber sprouting (MFS) in the dentate gyrus is a common pathological change of epilepsy. Previous studies suggested that it is associated with drug-resistant epilepsy, and mossy cells control spontaneous seizures and spatial memory. METHODS We investigated the correlations among cognitive impairment, MFS, seizure frequency and drug resistance in a rat model of epilepsy induced by lithium-pilocarpine. Phenytoin and phenobarbital were used to screen drug resistance. Cognitive function and MFS were detected through the novel object recognition (NOR) test, Morris water maze (MWM) test and Timm staining. RESULTS The results showed that object memory and spatial memory functions were both significantly impaired in rats with epilepsy, and only spatial memory impairment was more severe in rats with drug-resistant epilepsy. More frequent spontaneous seizures and more obvious MFS were observed in the drug-resistant rats. The seizure frequency was significantly associated with the MWM performance but not with the NOR performance in rats with epilepsy. The degree of MFS was significantly associated with seizure frequency and spatial memory function. CONCLUSION Taken together, these correlations among drug resistance, seizure frequency, spatial memory impairment and MFS suggested the possibility of a common pathological mechanism. More studies are needed to clarify the underlying mechanism behind these correlations and the detailed role of MFS in epilepsy. The mechanism of mossy cell change may be an important target for the treatment of seizures, drug resistance and cognitive dysfunction in patients with epilepsy.

Abstract
OBJECTIVES To study the molecular mechanisms of miR-18a aggravating intracranial hemorrhage (ICH) by increasing the blood-brain barrier (BBB) permeability. METHODS Brain microvascular endothelial cells (BMVECs) and astrocytes were isolated, identified, and co-cultured to establish in vitro BBB model. BMVECs co-cultured with astrocytes were stimulated with or without thrombase and then transfected with miR-18a mimic and/or si-RUNX1. The trans-endothelial electric resistance (TEER) and FlNa flux were measured, respectively. The potential interaction between RUNX1 and miR-18a was also detected. Additionally, SD rats were injected with fresh autologous non-anticoagulant blood into the brain basal ganglia to establish ICH model. After administration with miR-18a, sh-miR-18a, miR-18a+RUNX1, sh-miR-18a+sh-RUNX1, respectively, BBB permeability was assessed. RESULTS After overexpressing miR-18a, the expression levels of RUNX1, Occludin and ZO-1 were decreased, but the Evan's blue contents and brain water contents were significantly increased in ICH rats. Additionally, rat neurological function was impaired, accompanying with an increase of TEER and fluorescein sodium flux. MiR-18a was a direct target of RUNX1 and it could bind to the promoters of RUNX1 to inhibit the expression of Occuldin and ZO-1. Consistently, these phenomena could also be observed in the corresponding cell model. Conversely, miR-18a knockdown or RUNX1 overexpression just presented an improvement effect on ICH. CONCLUSIONS MiR-18a plays a critical role during ICH because it targets to RUNX1 to inhibit the expression of tight junction proteins (Occludin and ZO-1) and then disrupt BBB permeability. MiR-18a might be a probable therapeutic target for ICH diseases.

Abstract
Purpose To evaluate polymyxin-resistant Klebsiella pneumoniae and Escherichia coli prevalence and characteristics in the Henan province, China. Materials and Methods A total of 2301 bacterial isolates collected at six hospitals were assessed. Their response to polymyxin was evaluated by minimum inhibitory concentration (MIC) analysis, and the mobilized colistin resistance (mcr) and carbapenemase gene were explored. Mutations on mgrB, phoPQ, pmrAB, and crrAB in polymyxin-resistant K. pneumoniae were detected by PCR. phoP, phoQ, pmrK, pmrA, pmrB, and pmrC transcriptional levels were quantified by RT-qPCR. Pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing were performed to determine the phylogenetic relationship between the polymyxin-resistant isolates. Results Of the E. coli and K. pneumoniae isolates identified, 0.3% and 1.4% were polymyxin-resistant, respectively, with MICs of 4–64 μg/mL. All polymyxin-resistant isolates were susceptible to tigecycline. Four E. coli isolates were mcr-1-positive and one was carbapenem-resistant, carrying blaNDM-5 and mcr-1. One K. pneumoniae isolate was mcr-1-positive and nine were carbapenem-resistant (PRCRKP), carrying blaKPC-2 but not mcr-1. The five E. coli isolates belonged to four sequence types (ST2, ST132, ST632, and ST983). All PRCRKP isolates belonged to ST11. However, all 16 isolates belonged to different PFGE types with <95% genetic similarity. Insertion sequences in mgrB were detected in nine (81.8%) polymyxin-resistant K. pneumoniae samples. Colistin resistance was linked with pmrHFIJKLM operon upregulation, with phoP, phoQ, and pmrK being overexpressed in all but one of the polymyxin-resistant K. pneumoniae samples. Furthermore, 33.3% of patients carrying polymyxin-resistant isolates had previously used polymyxin, and 66.7% patients displayed good clinical outcomes. Conclusion The K. pneumoniae polymyxin resistance rate was slightly higher than that of E. coli and mcr-1 was more common in E. coli than in K. pneumoniae. Moreover, the insertion of ISkpn14 into mgrB may be the main contributor to polymyxin-resistance in K. pneumoniae in Henan.

Abstract
Background To observe the therapeutic effect of conventional decompressive craniectomy with hematoma evacuation and frame-based stereotactic minimally invasive surgery (MIS) for supratentorial intracranial hematoma with herniation. Methods One hundred forty-nine patients with hypertensive ICH complicated with tentorial herniation were reviewed and analyzed in the present study. The intracranial hematoma was evacuated by emergency surgery within 6 h after admission. According to the authorized representatives’ wishes and consent, 74 of the 149 patients were treated by conventional decompressive craniectomy followed by hematoma removal, defined as the CDC group, and the remaining 75 patients underwent frame-based stereotactic MIS for ICH evacuation, defined as the MIS group. The intervals between the admission to surgery, the duration of surgery, the amount of iatrogenic bleeding, the occurrence of postoperative rebleeding, and the recovery of neurological functions were compared between the two groups. All patients were followed up for 3 months. Secondary epilepsy, survival in a vegetative state, severe pulmonary complications, mortality, and activities of daily living (ADL) classification were also recorded and compared. Results The interval between admission and surgery, the duration of surgery, and intraoperative blood loss in the MIS group were significantly decreased compared to the CDC group. The mortality rate, the rate of rebleeding, prevalence of vegetative state, and severe pulmonary complications in the MIS group were remarkably decreased compared to the CDC group. In the MIS group, the survivors’ (ADL) grade also showed advantages. Conclusions In the surgical treatment of hypertensive ICH complicated with tentorial herniation, frame-based stereotactic MIS for ICH showed advantages compared to conventional open surgery.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic debilitating lung disease, characterized by progressive airway inflammation and lung structural cell death. Cigarette smoke is considered the most common risk factor of COPD pathogenesis. Understanding the molecular mechanisms of persistent inflammation and epithelial apoptosis induced by cigarette smoke would be extremely beneficial for improving the treatment and prevention of COPD. A histone methyl modifier, protein arginine N-methyltransferase 6 (PRMT6), is reported to alleviate cigarette smoke extract (CSE)-induced emphysema through inhibiting inflammation and cell apoptosis. However, few studies have focused on the modulation of PRMT6 in regulating inflammation and cell apoptosis. In this study, we showed that protein expression of PRMT6 was aberrantly decreased in the lung tissue of COPD patients and CSE-treated epithelial cells. FBXW17, a member of the Skp1-Cullin-F-box (SCF) family of E3 ubiquitin ligases, selectively bound to PRMT6 in nuclei to modulate its elimination in the proteasome system. Proteasome inhibitor or silencing of FBXW17 abrogated CSE-induced PRMT6 protein degradation. Furthermore, negative alteration of FBXW17/PRMT6 signaling lessened the proapoptotic and proinflammatory effects of CSE in lung epithelial cells. Our study, therefore, provides a potential therapeutic target against the airway inflammation and cell death in CS-induced COPD.

Abstract
A patient with thymoma associated immunodeficiency syndrome (Good's syndrome) and bronchiectasis was retrospectively analyzed. Good's syndrome is a rare condition of immunodeficiency that is characterized by thymoma and hypogammaglobulinemia. It is important to bear in mind that Good's syndrome should be included in the differential diagnosis When patients repeatedly visited for bronchiectasis or infection, we should alert to their immune state and history of thymoma. Early screening of immunological status and aggressive correction of immune deficiency are beneficial to improving the prognosis to patients with Good's syndrome.

Abstract
BACKGROUND Blend sign on initial computed tomography (CT) is associated with poor outcome in patients with intracerebral hemorrhage (ICH). However, the mechanisms underlying the blend sign formation are poorly understood. The present study aimed to explore the possible mechanism of the CT blend sign in patients with ICH. METHODS Seventy healthy rabbits were selected to prepare an ICH model. The animals were assigned to a whole blood group + whole blood group (ww group, 50 rabbits), a whole blood + plasma group (wp group, 10 rabbits) or a whole blood + serum group (ws group, 10 rabbits). The animals of the ww group were allocated to five subgroups based on the interval between the first infusion of blood and the second one. The subgroups included ww 1 h group (with an interval of 1 h), ww 2 h group, ww 3 h group, ww 4 h group and ww 5 h group. The rabbits from each group received first infusion of 0.3 mL of whole blood into the basal ganglia area to form a hematoma. Then, they received a second infusion of the same amount of whole blood, plasma or serum into the brain to form another hematoma adjacent to the first one. RESULTS A hematoma with two densities on brain CT could be formed in each group after a second infusion of blood into the brain. A significant difference in CT attenuation values was observed between the hyperattenuation and the hypoattenuation in all the groups. However, only the morphological features of the hematoma in the ww group was in accordance with the CT blend sign observed in humans. The CT attenuation values in the hypodensity area of the ww 4 h group or the ww 5 h group were decreased compared with the ww 1 h group to the ww 3 h group. CONCLUSIONS The CT blend sign observed in humans might be composed of two parts of blood with different ages. The hypodense area might be blood with older age and the hyperdense area might be new bleeding.

Abstract
OBJECTIVES To compare the ability of detailed routine ultrasound examination, performed without knowledge of maternal serology and fetal status, with that of targeted prenatal imaging performed in prenatal diagnostic units in cases of known fetal infection to identify cytomegalovirus (CMV)-infected fetuses that will develop long-term sequelae. METHODS All prenatal imaging reports were collected for 255 children with congenital CMV in a registered cohort between 2013 and 2017 (NCT01923636). All women had undergone detailed routine fetal ultrasound examination at 20-24 and 30-34 weeks as part of routine antenatal care. All cases of known fetal CMV infection had also undergone targeted prenatal ultrasound examination. Postnatal structured follow-up for up to 48 months of age involved clinical, audiological and neurological assessment, including Brunet-Lezine scoring. Long-term sequelae (> 12 months) were considered to be mild in cases with isolated unilateral hearing loss and/or vestibular disorders, and severe in cases with bilateral hearing loss and/or neurological sequelae. All imaging reports were analyzed retrospectively with the knowledge of congenital CMV infection, searching for reference to findings that were, or could have been, related to fetal infection. Findings were analyzed in relation to whether the cases were diagnosed with CMV in utero or only postnatally. RESULTS There were 237 children with complete follow-up data (> 12 months), for a median of 24 (range, 12-48) months. Of these, 30% (71/237) were diagnosed with CMV prenatally and 70% (166/237) were diagnosed within 3 weeks after birth. 72.5% (29/40) of children with long-term sequelae, including 74% (14/19) with severe long-term sequelae, were not identified in the prenatal period. Among those diagnosed prenatally, the sensitivity of prenatal imaging for predicting long-term sequelae and severe long-term sequelae was 91% and 100%, respectively, while, in the group diagnosed only postnatally, non-specific infection-related ultrasound findings had been reported without raising suspicion in 48% of cases with long-term sequelae and 64% of those with severe long-term sequelae. CONCLUSIONS Routine detailed ultrasound examination in pregnancy is not an appropriate screening tool for congenital CMV infection that leads to long-term sequelae, in contrast with the high performance of targeted prenatal imaging in known cases of fetal infection. The non-specific nature of ultrasound features of CMV and their evolution, and a lack of awareness of caregivers about congenital CMV, are likely explanations. Awareness of the sonologist regarding congenital CMV and knowledge of the maternal serological status in the first trimester seem key to the performance of prenatal ultrasound.
