Objective To explore the potential prognostic factors of patients with acute ischemic stroke(AIS)after undergoing endovascular mechanical thrombectomy and to construct an effective predictive model.Methods A retrospective analysis of clinical data was conducted on 202 patients with anterior circulation large vessel occlusion AIS from 2 stroke centers.All patients received endovascular mechanical thrombectomy treatment,with treatment and follow-up lasting at least 90 d.Basic demographic characteristics,medical records,and baseline blood biomarker data were collected,and the potential prognostic indicators for AIS after 90 d were screened using least absolute shrinkage and selection operator(LASSO)-logistic regression analysis.Results It was found that alcohol drinking(P=0.029),hypertension(P=0.001),diabetes mellitus(P=0.021),stroke or transient ischemic attack(P=0.049),systolic blood pressure on admission(P=0.009),diastolic blood pressure on admission(P=0.038),blood glucose(P=0.003),white blood cell count(P=0.001),neutrophil count(P=0.001),fibrinogen(P=0.010),systemic immune-inflammation index(P=0.008)and neutrophil-to-lymphocyte ratio(NLR)(P＜0.001)were associated with adverse clinical outcomes.Nine significant prognostic determinants were screened through LASSO-logistic regression analysis.Multivariate logistic regression analysis revealed that male sex(P=0.008),smoking history(P=0.013),hypertension(P=0.011),lymphocyte(P=0.028),fibrinogen(P=0.016),and NLR(P＜0.001)were significant predictive factors for poor prognosis in AIS patients after endovascular thrombectomy treatment.The constructed prognostic model had an accuracy of 76.2％,a sensitivity of 78.2％,a specificity of 71.7％,and a positive predictive value of 86.7％.Conclusion The predictive model established in this study can assist clinicians in identifying high-risk patients with AIS who have undergone endovascular thrombectomy,and it provide guidance for formulating individualized treatment strategies.

Objective:To explore the diagnostic value of the macrophage activation syndrome/systemic juvenile idiopathic arthritis（MS）score in macrophage activation syndrome（MAS）associated with systemic juvenile idiopathic arthritis（sJIA），and to provide a reference for clinical work.Methods:This study was a retrospective case-control analysis，conducted on the patients initially diagnosed as sJIA-associated with MAS and admitted into the Department of Rheumatology and Immunology of Children's Hospital Affiliated to Xi 'an Jiaotong University from July 1st，2016 to June 30th，2023. All of the patients met the diagnostic criteria for patients with MAS associated with sJIA according to the 2016 European Alliance of Associations for Rheumatology（EULAR）/American College of Rheumatology（ACR）/Pediatric Rheumatology International Trials Organization（PRINTO）standards. The basic information at baseline，clinical manifestations，and auxiliary examination results were collected. The MS score was applied to re-evaluate the children diagnosed as sJIA-associated with MAS. When the MS score ≥-2.1，the possibility of sJIA with MAS was high. Thirty cases of sJIA without MAS were randomly selected as the control group.Results:There were 28 cases in the MAS group，including 13 males（46.43%）and 15 females（53.57%），with an average age of（7.51±4.01）years. Compared with the control group，the MAS group were significantly more likely to have high fever（ χ2=8.539， P=0.003），hepatomegaly（ χ2=11.621， P<0.001），splenomegaly（ χ2=11.710， P<0.001）and neurological involvement（ χ2=27.619， P<0.001），with the differences being statistically significant. Meanwhile，there were statistically significant differences between the two groups in terms of white blood cell count（ Z=-4.001， P<0.001），neutrophil count（ Z=-3.659， P<0.001），platelet count（ Z=-4.687， P<0.001），albumin level（ Z=-4.018， P<0.001），alanine aminotransferase（ Z=-3.846， P<0.001），aspartate aminotransferase（ Z=-5.932， P<0.001），lactate dehydrogenase（ Z=-6.150， P<0.001），triglycerides（ Z=-5.874， P<0.001），fibrinogen（ Z=-5.808， P<0.001），ferritin（ Z=-5.280， P<0.001），erythrocyte sedimentation rate（ Z=-3.971， P<0.001），ferritin/erythrocyte sedimentation rate（ Z=-5.433， P<0.001），reduction of two-line cells in blood（ χ2=11.408， P<0.001）and the presence of hemophagocytosis in bone marrow smears（ χ2=28.260， P<0.001）. Moreover，there was a statistically significant difference in MS scores between the two groups（ Z=-6.148， P<0.001），with higher MS scores in the MAS group. Nevertheless，this study showed the median MS scores of both groups ≥-2.1. Conclusion:The MS score was significant to a certain degree as reference for the diagnosis of MAS，and this study showed that the MS score in the MAS group was significantly higher than the control group. However，the median MS scores in both groups were no less than -2.1. This might be related to the influence of factors during the assessment，which made it necessary to optimize the cutoff values of the MS score. Therefore，prospective studies should be carried out on the role of MS score in early identification of MAS.

Objective:To evaluate the clinical efficacy of Cai's gynecological nourishing kidney therapy for patients with diminished ovarian reserve (DOR).Methods:A randomly controlled trail was conducted. A total of 63 patients with DOR who were treated in the gynecology outpatient clinic of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine from September 2020 to January 2022 were set as observation subjects, and were divided into control group ( n=31) and observation group ( n=32) according to the random number table method. The patients in the control group were treated with Femoston, and the patients in the observation group were treated with Cai's gynecological nourishing kidney therapy on the basis of Femoston treatment. Both groups were treated for 3 menstrual cycles. Both antral follicle count (AFC) was performed by vaginal ultrasound, serum levels of TGF-β1, IL-1β, IL-2, IL-6 and IL-21 were detected by ELISA, and serum levels of FSH, LH, E2, anti-Müllerian hormone (AMH) and MDA were detected by biochemical methods. The TCM syndrome score was used to evaluate the severity of symptoms, and the menstrual score was used to evaluate the abnormal menstruation. Clinical efficacy was evaluated. Results:The total effective rate was 87.50% (28/32) in the observation group and 58.06% (18/31) in the control group, with statistical significance ( χ2=8.42, P=0.004). After treatment, the AFC in the observation group (3.93±2.32 vs. 2.21±2.18, t=3.03) was higher than that of the control group ( P<0.01). After treatment, the serum FSH level of the observation group [10.05 (8.35, 21.48) IU/L vs. 20.60 (8.00, 43.30) IU/L, Z=2.18] was lower than that of the control group ( P<0.05), and the level of AMH [0.19 (0.03, 0.47) μg/L vs. 0.02 (0.01, 0.24) μg/L, Z=-1.54] in the observation group was higher than that of the control group ( P<0.05). The serum levels of TGF-β1 [(68.27±11.76) ng/L vs. (55.33±13.03) ng/L, t=4.14] and IL-1β [(58.00±7.53) ng/L vs. (52.31±8.06) ng/L, t=2.89] in the observation group were higher than those in the control group, and the levels of IL-6 [(33.26±7.45) ng/L vs. (40.69±11.69) ng/L, t=3.02], the level of IL-21 [(118.37±15.56) ng/L vs. (140.43±25.51) ng/L, t=-4.04] was lower than that of the control group ( P<0.01). Conclusions:Cai's gynecological nourishing kidney therapy combined with Fenmaotong can effectively increase the AFC of DOR patients and improve clinical efficacy. Its mechanism of action may be related to reducing serum FSH and LH levels and increasing E2 levels.

Objective To observe the changes of laboratory blood indexes in patients with intrahepatic cholestasis of pregnancy(ICP),and analyze the value of blood inflammation indexes and liver function indexes in the diagnosis of ICP and the prediction of delivery mode.Methods A total of 251 patients diagnosed with ICP in this hospital from January 2021 to December 2022 were selected as the ICP group,and another 200 healthy pregnant women were selected as the control group.The patients with ICP were further divided into the severe ICP group(n=47)and the mild ICP group(n=204),the vaginal delivery group(n=113)and the cesarean section group(n=138)according to the severity of ICP and delivery mode.Mann-Whitney U test was used for comparison of parameters between groups,and Spearman method was used for correlation analy-sis.Receiver operating characteristic(ROC)curves were used to evaluate the efficacy of laboratory indicators in diagnosing ICP and predicting delivery mode.Results Neutrophil/lymphocyte ratio(NLR)[6.01(4.45,8.37)vs.3.36(4.12,3.51)]and aspartate transaminase(AST)level[20.00(16.00,33.00)U/L vs.15.00(13.00,18.00)U/L]in the ICP group were significantly higher than those in the control group(P＜0.05),and NLR in the severe ICP group was significantly higher than that in the mild ICP group[4.93(3.87,7.35)vs.4.14(3.12,5.17),P＜0.05].Correlation analysis showed that NLR was positively correlated with AST level(r=0.279,P＜0.001)and ICP severity(r=0.139,P=0.028)in patients with ICP.The area under ROC curve(AUC)of NLR combined with AST for ICP diagnosis was 0.882(95％CI:0.851-0.913).In ad-dition,cholinesterase(CHE)[6 020.00(5 499.50,6 703.50)U/L vs.5 341.50(4 651.75,6 259.25)U/L]and prealbumin(PA)[199.00(177.71,225.20)mg/Lvs.169.17(139.18,204.40)mg/L]levels in the va-ginal delivery group were significantly higher than those in the cesarean section group(P＜0.05),and the AUC of CHE combined with PA for predicting vaginal delivery in ICP patients was 0.727(95％CI:0.664-0.789).Conclusion NLR and AST have potential value in the diagnosis of ICP,and CHE and PA have poten-tial value in predicting delivery mode of ICP patients.

Objective:To understand the monkeypox knowledge awareness, risk perception and vaccination intention in men who have sex with men (MSM) in five cities in northeast China.Methods:A cross-sectional study was conducted by using electronic questionnaire in MSM selected by convenience sampling in five cities in northeast China (Shenyang, Panjin, Changchun, Harbin and Jiamusi) from June 28 to July 8, 2023 by local centers for disease control and prevention and MSM communities. The sample size was estimated to be 220. Information about their demographics, monkeypox-related knowledge awareness, perceived concern about epidemic risk perception, and monkeypox vaccination intention were collected. Logistic regression model was used to analyze related factors for MSM's monkeypox vaccination intention.Results:In 355 MSM, 63.9% (227/355) had monkeypox vaccination intentions, and 55.5% (197/355) had high awareness of monkeypox related knowledge with a mean knowledge awareness score of 3.7±1.5. MSM with education level of high-school and above (a OR=1.93, 95% CI:1.01-3.69), higher knowledge awareness score (a OR=1.19, 95% CI:1.02-1.40) and higher risk perception of monkeypox infection (a OR=1.82, 95% CI:1.15-2.88), were more willing to receive monkeypox vaccination. The main reasons for willingness to receive monkeypox vaccine were preventing monkeypox (86.3%, 196/227) and worrying about appearance being affected (62.1%, 141/227). The main reasons for unwillingness for the vaccination included concerns about vaccine safety (53.1%, 68/128), clinical progression of AIDS being affected (46.1%, 59/128) and efficacy of antiretroviral therapy being affected (44.5%, 57/128). Conclusions:The levels of knowledge awareness and vaccine intentions still need to be improved among MSM in five cities of northeast China. It is necessary to improve the awareness of monkeypox and intention of monkeypox vaccination, promote protected sex behavior and self-assessment of infection risk, reduce vaccine hesitancy and increase monkeypox vaccination intention in MSM in 5 cities in northeast China.

Liver metastases (LMs) are common in lung cancer. Despite substantial advances in diagnosis and treatment, the survival rate of patients with LM remains low as the immune-suppressive microenvironment of the liver allows tumor cells to evade the immune system. The impact of LMs on the outcomes of immune checkpoint inhibitors in patients with solid tumors has been the main focus of recent translational and clinical research. Growing evidence indicates that the hepatic microenvironment delivers paracrine and autocrine signals from non-parenchymal and parenchymal cells. Overall, these microenvironments create pre- and post-metastatic conditions for the progression of LMs. Herein, we reviewed the epidemiology, physiology, pathology and immunology, of LMs associated with non-small cell lung cancer and the role and potential targets of the liver microenvironment in LM in each phase of metastasis. Additionally, we reviewed the current treatment strategies and challenges that should be overcome in preclinical and clinical investigations. These approaches target liver elements as the basis for future clinical trials, including combinatorial interventions reported to resolve hepatic immune suppression, such as immunotherapy plus chemotherapy, immunotherapy plus radiotherapy, immunotherapy plus anti-angiogenesis therapy, and surgical resection.

Objective:To analyze hip joint movement during the swing phase of the strides of stroke survivors with hemiplegia and foot drop.Methods:Thirty stroke survivors with hemiplegia and foot drop formed the observation group, while thirty matched healthy counterparts were the control group. A three-dimensional gait analysis system was used to compare the hip and ankle joint kinematics on the hemiplegic side of the observation group members with those on the corresponding side of a matched control. Pearson correlation related the maximum plantar flexion angle of the ankle and hip joints in the observation group.Results:Compared with the control group, there was a significant increase in the maximum abduction and external rotation of the hip joint during the swing phase, but a significant decrease in the maximum extension, flexion, adduction, internal rotation. The range of motion of the hip joint in the sagittal, frontal and horizontal planes was significantly smaller, as was the maximum dorsiflexion and sagittal range of motion of the ankle joint. The maximum plantar flexion angle of the ankle was positively correlated with the hip joint′s maximum flexion, maximum external rotation and sagittal joint motion, but negatively correlated with the hip′s horizontal motion.Conclusion:In stroke survivors with hemiplegia and ptosis, significant changes are observed in the three-dimensional motion during the swing phase of a stride. The mode of hip joint compensation changes depending on the severity of the foot drop.

Objective To investigate the application effect of external treatment method of Xingqi Huoxue Zhitong Paste in the treatment of phlebitis. Methods Using mannitol as an inflammatory agent, a phlebitis model was established by infusion into the ear marginal vein of rabbits. Successfully modeled rabbits were randomly divided into four subgroups for intervention, while the blank control group was routinely raised without any intervention. After the intervention, the improvement effect of Xingqi Huoxue Zhitong Paste on mannitol-induced transfusion-induced phlebitis in rabbits was explored by observing the manifestations of phlebitis, serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor A (VEGF-A) levels. Results The success rate was up to 90.0%. On the first day of treatment, there were 8 ineffective cases and 1 effective case in the saline group; 6 ineffective cases and 3 effective cases in the hirudoid group; 7 ineffective cases and 2 effective cases in the magnesium sulfate group; 7 ineffective cases and 2 effective cases in the Xingqi Huoxue Zhitong Paste group. There was no significant difference in the curative effect among the four groups (P=0.431). On the fourth day of treatment, there were 5 ineffective cases, 2 effective cases, and 2 markedly effective cases in the saline group; 1 effective case, 5 markedly effective cases, and 3 cured cases in the hirudoid group; 2 effective cases, 5 markedly effective cases, and 2 cured cases in the magnesium sulfate group; 2 effective cases, 4 markedly effective cases, and 3 cured cases in the Xingqi Huoxue Zhitong Paste group. On the fourth day of treatment, compared with the saline group, the curative effects of the hirudoid group (P=0.001), the magnesium sulfate group (P=0.020), and the Xingqi Huoxue Zhitong Paste group (P=0.003) were statistically significant. There was no significant difference in curative effect in the magnesium sulfate group and the Xingqi Huoxue Zhitong Paste group when compared with the hirudoid group (P>0.05); there was no significant difference in curative effect in the Hirudoid group and the Xingqi Huoxue Zhitong Paste group when compared with the magnesium sulfate group (P>0.05); there was no significant difference in curative effect in the hirudoid group and the magnesium sulfate group when compared with the Xingqi Huoxue Zhitong Paste group (P>0.05). The effective rate of the saline group was 11.1%, and the cure rate was 0%. The effective rate of the hirudoid group was 100.0%, and the cure rate was 33.3%. The effective rate of the magnesium sulfate group was 77.7%, and the cure rate was 44.4%. The effective rate of the Xingqi Huoxue Zhitong Paste group was 66.7%, and the cure rate was 22.2%. The drug effectiveness of the Xingqi Huoxue Zhitong Paste group, the hirudoid group, and the magnesium sulfate group was higher than that of the saline group (P < 0.05). After the intervention, the levels of serum inflammatory factors IL-6, TNF-α, and VEGF-A in the four model subgroups were statistically significant compared with the blank control group (P < 0.05). The levels of serum inflammatory factors IL-6, TNF-α, and VEGF-A in the saline group showed significant difference from those in the hirudoid group, the magnesium sulfate group, and the Xingqi Huoxue Zhitong Paste group (P < 0.05). Compared with the hirudoid group, the differences in serum inflammatory factors IL-6, TNF-α, and VEGF-A contents in the magnesium sulfate group and the Xingqi Huoxue Zhitong Paste group were statistically significant (P < 0.05). The inflammatory factor levels in the blank control group were the lowest, while those in the normal saline group were the highest. Conclusion Xingqi Huoxue Zhitong Paste group has an improving effect on mannitol-induced infusion phlebitis in rabbits, but its efficacy is inferior to that of the commonly used hirudoid ointment. Therefore, appropriate adjustments and improvements can be made to the drug formula to enhance its effectiveness.

Metastasis is the leading cause of cancer-related death. Despite extensive treatment, the prognosis for patients with metastatic cancer remains poor. In addition to conventional surgical resection, radiotherapy, immunotherapy, chemotherapy, and targeted therapy, various nanobiomaterials have attracted attention for their enhanced antitumor performance and low off-target effects. However, nanomedicines exhibit certain limitations in clinical applications, such as rapid clearance from the body, low biological stability, and poor targeting ability. Biomimetic methods utilize the natural biomembrane to mimic or hybridize nanoparticles and circumvent some of these limitations. Considering the involvement of immune cells in the tumor microenvironment of the metastatic cascade, biomimetic methods using immune cell membranes have been proposed with unique tumor-homing ability and high biocompatibility. In this review, we explore the impact of immune cells on various processes of tumor metastasis. Furthermore, we summarize the synthesis and applications of immune cell membrane-based nanocarriers increasing therapeutic efficacy against cancer metastases via immune evasion, prolonged circulation, enhanced tumor accumulation, and immunosuppression of the tumor microenvironment. Moreover, we describe the prospects and existing challenges in clinical translation.
