Objective:To investigate the prognostic value of platelet volume indices (PVIs), neutrophil/lymphocyte ratio (NLR) and the combination of these parameters for the neurological function of acute ischemic stroke (AIS) patients after intravenous thrombolysis.Methods:From January 2016 to January 2019, the data of 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were retrospectively analyzed. The patients were divided into two groups according to modified rank in scale (MRS) score: MRS≤2 and MRS≥3. The general information, past medical history and laboratory examination results of each group were compared. Logistic regression analysis was used to analyze the risk factors of poor prognosis of neurological function in AIS patients with thrombolysis.Results:NLR ( OR=1.045, 95% CI: 1.032-2.350, P=0.032), mean platelet volume (MPV) ( OR=4.212, 95% CI:1.074-16.513, P=0.039), MPV×NLR/PLT ( OR=5.711, 95% CI: 1.342-24.298, P=0.018), platelet distribution width (PDW) ( OR=1.015, 95% CI: 1.001-2.372, P=0.032), and NIHSS score ( OR=1.266, 95% CI: 1.111-1.443, P<0.01) were related with poor prognosis neurological function of AIS patients with intravenous thrombolysis. Conclusions:MPV, NLR, MPV×NLR/PLT PDW and NIHSS scores are the risk factors for poor prognosis of neurological function in AIS patients with thrombolysis. MPV×NLR/PLT can predict the neurological severity of AIS after 3 months.

Objective:To investigate the relationship between neutrophil to lymphocyte ratio (NLR) and the severity of acute ischemic stroke (AIS) and the prognosis of patients undergoing intravenous thrombolysis (IVT).Methods:From January 2016 to January 2019, 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were studied retrospectively. According to the NLR value, 147 patients were divided into the NLR 2 or less group ( n=37) or less, 2 < NLR < 3 group ( n=31), and the NLR≥3 group ( n=79). General data, medical history, laboratory examination results, NIHSS score and mRS score of patients in each group were compared. Logistic regression analysis was used to analyze the relationship between NLR and severity of acute ischemic stroke patients and clinical prognosis with thrombolysis. Results:NLR was associated with AIS stroke severity ( OR=2.044, 95% CI: 1.011-8.566, P=0.006). NLR was associated with poor prognosis of AIS neurological function with thrombolysis ( OR=3.744, 95% CI: 0.997-4.713, P=0.003). However, NLR was not associated with AIS death after thrombolysis ( OR=0.591, 95% CI: 0.750-1.933, P=0.442). Conclusions:NLR was associated with the severity of stroke in AIS patients and the prognosis of poor neurological function with thrombolysis.

Objective To evaluate the efficacy of rescue treatment for recurrent esophageal cancer after radical esophagectomy, and to provide insights into the development of comprehensive treatment for esophageal cancer.Methods The clinical data of 218 patients who were confirmed with recurrent metastatic esophageal cancer after R0 resection and received rescue treatment in our hospital from 2004 to 2014 were retrospectively reviewed.The survival rate was determined by the Kaplan-Meier method.Univariate and multivariate prognostic analyses were performed using the log-rank test and Cox proportional hazards model, respectively.Results The median post-recurrence follow-up time was 53 months.The 1-and 3-year overall survival (OS) rates after recurrence were 57.2% and 24.4%, respectively.Among the 163 patients with local recurrence, the 1-and 3-year OS rates were 70% and 42% for patients treated with chemoradiotherapy (n=40), 55% and 24% for those with radiotherapy alone (n=106), and 23% and 8% for those with supportive therapy (n=13)(chemoradiotherapy vs.radiotherapy alone P=0.045, radiotherapy alone vs.supportive therapy P=0.004;none of the patients who were treated with chemotherapy alone survived for one year or more).Univariate analysis showed that N staging, TNM staging, and post-recurrence rescue treatment regimen were independent prognostic factors for esophageal cancer (all P=0.001).On the other hand, multivariate analysis indicated that only rescue treatment regimen was the independent prognostic factor for esophageal cancer (P=0.013).Conclusions Rescue chemoradiotherapy or radiotherapy alone can bring significant survival benefits for patients with recurrent and metastatic, especially locally recurrent, esophageal cancer following radical esophagectomy.

Objective:To investigate the relationship between thyroid stimulating hormone (TSH) level and thyroid peroxidase antibody (TPOAb) status in the first trimester on pregnancy outcomes.Methods:A total of 2 095 pregnant women with complete clinical data from department of pregnancy endocrinology or department of obstetrics in Dongying People′s Hospital from January 1, 2018 to November 31, 2019.According to the TSH level detected before 12 + 6 weeks of gestation, all pregnant women were divided into normal TSH (0.1 μIU/ml≤TSH< 2.5 μIU/ml), high TSH (2.5 μIU/ml≤TSH≤4.0 μIU/ml), sub-clinical hypothyroidism during gestation (4.0 μIU/ml0.05). Multivariate logistic regression analysis of gestational diabetes mellitus and preterm delivery showed that the risk of gestational diabetes mellitus was significantly increased in group F compared with the control group. Age, gestational status, and TPOAb positivity were risk factors for gestational diabetes. The risk of premature birth in group D, group E and group F was higher than that in the control group [odds ratio ( OR)>1]. Age and TPOAb positivity were risk factors for preterm delivery in pregnant women ( OR>1, P<0.05). Conclusions:TPOAb positive in early pregnancy combined with subclinical hypothyroidism in pregnancy will increase the risk of gestational diabetes, while TPOAb positive in early pregnancy combined with TSH on the high side or subclinical hypothyroidism in pregnancy will increase the risk of premature delivery, so the management of such pregnant women should be strengthened and active treatment should be given if necessary.

Methods: The median sagittal diameter and transverse diameter of the spinal canal from C2 to C7 were measured on CT images. The ratio of the median sagittal diameter to the transverse diameter was calculated. Accordingly, the spinal canal shape of each segment was classified into four, and the specific criteria of lunar phase classification were determined through linear discriminant analysis based on the ratio of the median sagittal diameter to the transverse diameter. The inter-rater reliability of the classification was explored using Kappa coefficients. Finally, the morphology of the different segments of the cervical spinal canal in healthy volunteers was revised and compared. Results: According to the ratio of the median sagittal diameter and the transverse diameter of the cervical spinal canal, the lunar phase classification of the cervical bony spinal canal was determined as follows: full-moon >0.65, 0.55< convex-moon ≤0.65, 0.46≤ quarter-moon ≤0.55, and residual-moon <0.46. The Kappa values of C2–C7 were 0.851, 0.958, 0.823, 0.927, 0.793, and 0.946, and the Kappa value of all C2–C7 segments was 0.854 that mainly presented two forms of full-moon (76.5%) and convex-moon (23.0%). A quarter-moon spinal canal was mainly distributed in C3, C4, C5, and C6; a residual-moon spinal canal was mainly distributed in C4 and C5; and the morphological distribution of C4 and C5 were similar (p>0.05). The frequency of the spinal canal of the residual-moon type was the highest, and the full-moon (6.5%) and residual-moon (7.5%) types of C7 were rare. Conclusions The morphological classification of the cervical spinal canal was established to present anatomical variations. The classification showed good inter-rater reliability.

Objective To investigate the psychological demands of caregivers who take care of severe craniocerebral trauma patients, and to analyze different psychological needs of caregivers in different relation, such as parents, spouses, children, brothers and sisters. Methods We used the Critical Care Family Needs Inventory to investigate 391 relatives of patients in neurosurgical intensive care unit in four hospitals by stratified sampling, in order to understand the psychological demands of people who take care of severe craniocerebral trauma patients. Results The total demand score of 391 caregivers was (136. 63 ± 18. 56),which was at the moderate level. There was significant different demand of different relative caregivers in information factor, proximity factor and assurance factor (F=5. 103, 5. 032, 7. 811, respectively;P<0. 01). Conclusions The psychological demands of caregivers who take care of severe craniocerebral trauma patients had relative high psychological needs. The clinic staffs should pay attention to the difference of demand, and give them psychological care to reduce their psychological stress and prevent mental problems.

Objective To explore the incidence and related predictive factors for acute symptomatic esophagitis in patients with locally advanced non?small cell lung cancer ( NSCLC ) treated with intensity?modulated radiation therapy ( IMRT) . Methods Data were collected retrospectively from 256 patients with inoperable or unresectable stage Ⅲ NSCLC treated in our hospital between January 2007 and December 2011. The radiotherapy target volume included primary lung cancer and lymphatic drainage area involved,with a median dose of 60 Gy in 30 fractions (50-70 Gy).Of all the patients,109 patients (42.6%) received concurrent chemotherapy. Grade ≥2 acute esophagitis ( AE ) ( symptomatic esophagitis ) which occurred during radiotherapy and within 3 months after completion of radiotherapy served as the outcome event. National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0( NCI?CTCAE3.0) was used to evaluate the grade of AE. The logistic regression model was used to analyze the predictive factors. Results A total of 174 patients ( 68%) had treatment?related grade ≥2 AE;154 patients ( 60. 2%) had grade 2 AE and 20 patients (7.8%) had grade 3 AE.The median dose when grade≥2 AE occurred was 30 Gy (11?68 Gy).For grade≥2 AE,multivariate analysis showed that esophageal V5?V60,mean dose,and age were independent predictive factors (P=0.021,0,0.010).For grade ≥3 AE,multivariate analysis showed that esophageal V50?V60 ,concurrent chemotherapy,and body mass index ( BMI) were independent predictive factors ( P= 0.010,0.003,0.019 ) . Old age and higher BMI were the protective factors for grade≥2 and ≥3 AE, respectively. Conclusions For patients with locally advanced NSCLC treated with IMRT, esophageal V50—V60 and concurrent chemotherapy are predictive factors for grade ≥3 AE,and esophageal V50 has a high predictive value for both grade ≥2 and ≥3 AE.

Objective:To investigate the diagnostic efficacy of MRI-based or CT-based measurements and the combined evaluation methods for preoperative bone quality assessment in patients with cervical degenerative diseases.Methods:Patients who underwent spine surgery for cervical degenerative diseases at the Department of Orthopedics, Huashan Hospital, Fudan University from September 2020 to March 2022 with available preoperative X-ray, CT, MRI and dule energy X-Ray absorptiometry (DEXA) data were included in this study. Vertebral bone quality score (VBQ) based on MRI T1-weightedimages and CT Hounsfiled unit (HU) values of the cervical spine were measured, and a combined diagnostic formula based on the binary logistic regression was constructed. The patients were divided into normal bone mass (T≥-1.0) and osteopenia/osteoporosis groups (T<-1.0). The student's t-test and Chi-square test were performed for comparisons between groups. The Pearson correlation coefficient was also used to investigate the correlation between DEXA-T scores, cervical VBQ and CT HU values. In addition, receiver operating characteristic curve (ROC) were plotted to explore the diagnostic efficacy of VBQ, CT HU and their combined diagnosis. Meanwhile, the corresponding sensitivity and specificity were obtained. Results:A total of 71 patients were included in this study (17 in the normal group and 54 in the osteopenia/osteoporosis group). The student's t-test showed that VBQ (2.90±0.70 vs. 3.83±0.83, t=4.23, P<0.001) and CT HU values (370.26±85.38 vs. 295.20±67.96, t=3.73, P=0.002) were significantly different between the two groups. The area under the ROC curve (AUC) for VBQ and CT values of the cervical spine were 0.81 and 0.75, respectively, and the AUC for the combined diagnostic value constructed on the basis of both was 0.85. Applying VBQ scores alone had a diagnostic sensitivity of 80% and a specificity of 70%, and the combined diagnosis with VBQ and CT HU had a sensitivity of 90% and a specificity of 75%. Person correlation analysis showed a significant correlation between DEXA T value, cervical VBQ value and CT HU value. The detailed formula was: DEXA T score=-0.63×cervical VBQ+0.64 ( r=-0.55, P<0.001), CT HU value=-40.20×cervical VBQ+458.40 ( r=-0.45, P<0.001), DEXA T score=0.006×CT HU-3.47 ( r=0.45, P<0.001). Conclusion:This study confirmed the feasibility of using cervical VBQ values, CT HU values and combined diagnostics for preoperative bone density screening in patients with degenerative cervical spine diseases. This method allows surgeons to perform an initial preoperative bone density screening based on the patient's existing imaging data, and thus could aid in confirming the indication and scheme of surgery. The method could be a powerful tool for preoperative bone density assessment screening in patients with cervical degenerative diseases.

In recent years, with the development of neurointerventional techniques, transradial approach (TRA) has been able to meet most needs of neurointerventional procedures. Compared with tranfemoral approach (TFA), TRA can obviously reduce access-site complications, shorten hospital stays and improve patient satisfaction. However, due to the long learning curve, lack of radial-specific catheters, small artery diameter and specific vascular access-site complications, TRA development is relatively slow, and relevant domestic and foreign studies are still at initial stage. Therefore, this article mainly focuses on the anatomy, advantages and limitations, approaches of radial artery, and discuss the safety and feasibility of TRA in neurointerventional diagnosis and treatment, in order to provide more references for neurointerventionalists.
