    Abstract: Few studies have reported the clinical outcomes of older adult patients with acute anterior circulation large-vessel occlusion (LVO) who underwent mechanical thrombectomy (MT). Therefore, we investigated the safety, functional outcomes, and predictors of MT for anterior circulation LVO in older adults. We enrolled patients with acute anterior circulation LVO from May 2018 to October 2021 in this retrospective study. Patients were divided into older (≥80 years) and young ( 〈 80 years) groups. Multivariable logistic regression analyses determined the safety, functional outcomes, and predictors of MT for anterior circulation LVO. We divided 1182 patients with acute ischemic stroke into young (18-79 years; 1028 patients) and older (≥80 years; 154 patients) groups. Compared with the young group, the older group had more unfavorable functional outcomes and increased mortality ( P = .003). In the older adult patients, lower initial NIHSS score and higher ASPECTS were correlated with good outcomes. On the contrary, higher initial NIHSS score and lower ASPECTS were related to increased mortality. No difference was detected in symptomatic intracranial hemorrhage within 48 h between two groups. Increasing age was associated with lower rates of favorable functional outcomes and higher mortality rates. The lower initial NIHSS score combined with the higher ASPECTS may predict functional outcomes post-thrombectomy in older adults.

    Abstract: To investigate azoospermic factor (AZF) microdeletions in infertile men from northeastern China with karyotypic Y chromosome abnormalities. Methods G-banding of metaphase chromosomes and karyotype analysis were performed in all infertile male patients. Genomic DNA was isolated and used to analyze classical AZF microdeletions by PCR. The regions and sequence-tagged sites of AZFa (SY86, SY84), AZFb (SY127, SY134, SY143), and AZFc (SY152, SY254, SY255, SY157) were sequenced by multiplex PCR. Results A total of 190 Y chromosome abnormality carriers were found, of whom 35 had AZF microdeletions. These were most common in 46,X,Yqh− patients, followed by 45,X/46,XY patients. Most microdeletions were detected in the AZFb + c region, including 48.57% of all AZF microdeletion cases. AZF partial deletions were also seen in these patients. Overall, AZF microdeletions were detected in 38.5% Y chromosome abnormality carriers, and most were observed in 46,X,Yqh− individuals. Loss of SY152 was seen in all 35 patients, with SY254/SY255 detected in 34 of 35 patients. Conclusions AZF microdeletions were detected in 38.5% of Y chromosome abnormality carriers. This indicates that AZF microdeletion screening is advisable for individuals with karyotypic Y chromosome abnormalities.

    Abstract: The study on skip-N2 metastasis in small-cell lung cancer (SCLC) is lacking. Therefore, this study aimed to explore the prognostic significance of skip-N2 metastasis based on a multicenter cohort. Methods: We collected 176 SCLC patients with pathological categories T1-4N1-2M0 from four hospitals in China. Survival curves were drawn through the Kaplan–Meier method and compared by the log-rank test. The Cox regression method was used to calculate the hazard ratio (HR) and 95% confidence interval of the characteristics for cancer-specific survival (CSS). Two propensity-score methods were used to reduce the bias, including the inverse probability of treatment weighting (IPTW) and propensity-score matching (PSM). Results: This multicenter database included 64 pN1 patients, 63 non-skip-N2 cases, and 49 skip-N2 cases. Skip-N2 and the non-skip-N2 patients had gap CSS rates (skip-N2 no versus yes: 41.0% versus 62.0% for 1-year CSS, 32.0% versus 46.0% for 2-year CSS, and 20.0% versus 32.0% for 3-year CSS). After PSM, there were 32 pairs of patients to compare survival differences between N2 and skip-N2 diseases, and 34 pairs of patients to compare prognostic gaps between N1 and skip-N2 diseases, respectively. The results of IPTW and PSM both suggested that skip-N2 cases had better survival outcomes than the non-skip-N2 cases (IPTW-adjusted HR = 0.578; PSM-adjusted HR = 0.510; all log-rank p  〈  0.05). Besides, the above two analytic methods showed no difference in prognoses between pN1 and skip-N2 diseases (all log-rank p  〉  0.05). Conclusions: Skip-N2 patients were confirmed to have a better prognosis than non-skip-N2 patients. Besides, there was no survival difference between pN1 and skip-N2 cases. Therefore, we propose that the next tumor-node-metastasis staging system needs to consider the situation of skip metastasis with lymph nodes in SCLC.

    Abstract: Thymic carcinoma (TC) is a rare malignant tumor that can have a poor prognosis, and accurate prognostication prediction remains difficult. We aimed to develop a nomogram to predict overall survival (OS) and cancer-specific survival (CSS) based on a large cohort of patients. Methods: The Surveillance Epidemiology and End Results (SEER) database was searched to identify TC patients (1975–2016). Univariate and multivariable Cox regression analyses were used to identify predictors of OS and CSS, which were used to construct nomograms. The nomograms were evaluated using the concordance index (C-index), calibration curve, receiver operating characteristic curve, and decision curve analysis (DCA). Subgroup analysis was performed to identify high-risk patients. Results: The analysis identified six predictors of OS (Masaoka stage, surgical method, lymph node metastasis, liver metastasis, bone metastasis, and radiotherapy) and five predictors of CSS (Masaoka stage, surgical method, lymph node metastasis, tumor size, and brain metastasis), which were used to create nomograms for predicting three-year and five-year OS and CSS. The nomograms had reasonable C-index values (OS: 0.687 [training] and 0.674 [validation] , CSS: 0.712 [training] and 0.739 [validation] ). The DCA curve revealed that the nomograms were better for predicting OS and CSS, relative to the Masaoka staging system. Conclusion: We developed nomograms using eight clinicopathological factors that predicted OS and CSS among TC patients. The nomograms performed better than the traditional Masaoka staging system and could identify high-risk patients. Based on the nomograms’ performance, we believe they will be useful prognostication tools for TC patients.

    Abstract: Previous evidences have been proved that age, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and ejection fraction are tightly associated with the long-term outcomes in patients suffered from coronary artery disease (CAD). Therefore, the present study aimed to assess the prognosis value of age, NT-proBNP, and ejection fraction (ABEF) score in CAD patients who underwent percutaneous coronary intervention (PCI). Methods Observational cohort methodology was used in this study which enrolled totally 3561 patients. And the patients were followed up regularly for 37.59 ± 22.24 months. Patients were classed into three groups based on the tertiles of ABEF sore: first tertile ( 〈 5.06, n = 831), second tertile (5.06-6.25, n = 839), and third tertile (≥ 6.25, n = 834). The ABEF score was calculated as follows: age (years)/ejection fraction (%) + NT-proBNP (NT-proBNP 〈 177pg/mL was 1, 177≤NT-proBNP≥524pg/mL was 2 and NT-proBNP  〉  524pg/mL is 3). The association between ABEF score and adverse prognosis, including all-cause death (ACD), cardiac death (CD), major adverse cardiovascular events (MACEs) and major adverse cardiac and cerebrovascular events (MACCEs), in patients who underwent PCI was analyzed. Results According to the risk category of ABEF score, the incidences of ACD ( P  〈  .001), CD ( P  〈  .001) and MACCEs ( P = .021) among the three groups showed significant differences. Multivariate Cox regression analysis suggested that the respective risks of ACD and CD were increased 3.013 folds (hazard risk [HR] = 4.013 [95% confidence interval [CI] : 1.922-8.378], P  〈  .001) and 4.922 folds ([HR] = 5.922 [95% [CI] : 2.253-15.566], P  〈  .001) in the third tertile compared with those in the first tertile. Kaplan-Meier survival analyses showed that the cumulative risks of ACD,CD and MACCEs in patients with the high ABEF score tended to increase. Conclusion The present study indicated ABEF score was a novel biomarker suitable for predicting adverse prognosis in patients after PCI, which may be used for early recognition and risk stratification.

    Abstract: This article deals with the design of an integrated giant magnetoimpedance biochip combined with a sandwich immunoassay for the detection of alpha-fetoprotein, and we have offered the possible physical origins of the enhanced giant magnetoimpedance responses caused by Dynabeads. The giant-magnetoimpedance-based magnetic immunoassay showed a good sensitivity and specificity for the detection of 3 ng/mL alpha-fetoprotein. We also observed that there was significant difference in detection sensitivity between two giant magnetoimpedance biochips, which is probably related to the electroplating instability. Such an integrated giant magnetoimpedance biochip could be extended for the detection toward a wide spectrum of target biomolecules and shows promising potential for clinical applications.

    Abstract: Stem cells in different types may interact with each other to maintain homeostasis or growth and the interactions are complicated and extensive. There is increasing evidence that mesenchymal-epithelial interactions in early morphogenesis stages of both tooth and hair follicles show many similarities. In order to explore whether stem cells from one tissue could interact with cells from another tissue, a series of experiments were carried out. Here we successfully extracted and identified stem cells from human exfoliated deciduous teeth (SHED) of 8–12 years old kids, and then found that SHED could promote hair regeneration in a mouse model. In vitro, SHED shortened the hair regeneration cycle and promoted the proliferation and aggregation of dermal cells. In vivo, when SHED and skin cells of C57 mice were subcutaneously co-transplanted to nude mice, more hair was formed than skin cells without SHED. To further explore the molecular mechanism, epidermal and dermal cells were freshly extracted and co-cultured with SHED. Then several signaling molecules in hair follicle regeneration were detected and we found that the expression of Sonic Hedgehog (Shh) and Glioma-associated oncogene 1 (Gli1) was up-regulated. It seems that SHED may boost the prosperity of hairs by increase Shh/Gli1 pathway, which brings new perspectives in tissue engineering and damaged tissue repairing.

    Abstract: A new method has been developed for estimating the storage lengths of left-turn lanes at signalized intersections. To prevent lane overflow, the left-turn lane should be designed to have a length sufficient to store the longest expected queue. In this study, the left-turn queue length was estimated by considering two factors: (a) vehicles that arrive during the red phase and (b) the queue of vehicles carried over from previous cycles. A method based on the discrete-time Markov chain was applied to model the leftover queue length at the end of the green phase. A case study was provided to demonstrate the application of the proposed model. In the model evaluation, the estimated left-turn queue lengths were compared with field observations and estimates from other existing methods. The results showed that the proposed model significantly outperformed existing methods by providing more accurate estimates of the lengths of left-turn queues.

    Abstract: After successful primary percutaneous coronary intervention in ST-segment elevation myocardial infarction, adequate myocardial reperfusion is not achieved in up to 50% of patients. This phenomenon of no-reflow is associated with a poor in-hospital and long-term prognosis. Four main factors are thought to contribute to the occurrence of no-reflow: ischaemic injury; reperfusion injury; distal embolization; susceptibility of the microcirculation to injury. This review evaluates the literature, and in particular the clinical trials, concerned with pharmacological and physical methods for prevention and treatment of no-reflow. A number of drugs may improve no-reflow experimentally and clinically, but some have not yet been associated with conclusive improvements in clinical outcome. The complex interacting factors in no-reflow make it unlikely that any single agent will be effective for all patients. Confirmed methods known to be beneficial in the prevention of no-reflow (such as aspirin therapy, chronic statin therapy, blood glucose control, thrombus aspiration in patients with a high thrombus burden and ischaemic preconditioning) should be offered to patients as often as possible, to prevent and treat no-reflow.

    Abstract: The Prognostic Nutritional Index (PNI) has been reported to be correlated with long-term outcomes after gastrointestinal tumor surgery. However, to our knowledge, only a few studies have shown that the PNI is related to cardiovascular diseases. Therefore, we aimed to assess the association between the PNI and long-term outcomes in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). Methods This was retrospective observational study. A total of 3561 patients with CAD after PCI were retrospectively enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The patients (3519) were divided into three groups according to PNI tertiles: the first tertile (PNI  〈  47.12, n = 1173), the second tertile (47.12 ≤ PNI  〈  51.50, n = 1185), and the third tertile (PNI ≥ 51.50, n = 1161). The mean follow-up time was 37.59 ± 22.24 months. The primary endpoint long-term mortality, including all-cause mortality (ACM) and cardiac mortality (CM).Secondary endpoints were major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs). Result In our study, the incidences of ACM in the first, second, and third tertiles were 3.8%, 1.8% and 1.4%, respectively ( P  〈  0.001). The incidences of CM occurring in the first, second, and third tertiles were 1.7%, 3.1% and 2.1%, respectively ( P  〈  0.001).There was statistically significant different in primary endpoints incidence. MACEs occurred in 139 patients (11.8%) in the first tertile, 121 patients(11.1%) in the second tertile and 123 patients(10.8%) in the third tertile( P = 0.691). MACCEs occurred in 183 patients (15.6%) in the first tertile, 174 patients(14.7%) in the second tertile and 160 patients(13.85%) in the third tertile( P = 0.463).There was no statistically significant different in secondary endpoints incidence. Kaplan–Meier analyses showed that elevated PNI was significantly related to long-term CM (log rank, P   〈  0.001) and long-term ACM (log-rank, P   〈  0.001). Cox regression analyses suggested that compared with the patients in the first tertile, the risk of ACM was decreased to 60.9% (HR = 0.609, 95% CI: 0.398–0.932, P = 0.029) in the second tertile and 40.3%(HR = 0.403, 95% CI: 0.279–0.766, P = 0.003) in the third tertile, while the risk of CM was decreased to 58.8%(HR = 0.588, 95% CI: 0.321–0.969, P = 0.038) in the second tertile and 46.6%(HR = 0.466, 95% CI: 0.250–0.870, P = 0.017) in the third tertile. Multivariate Cox regression analyses showed that the PNI was an independent predictor of long-term ACM and CM. Conclusion Our finding shown that PNI is an independent predictor in CAD patients after PCI,the higher the PNI, the less occurring adverse event. Therefore,PNI may be an new biomarker to predict long-term outcome of CAD patients after PCI.
