Abstract
Reduced chemotactic migration of polymorphonuclear neutrophil (PMN) in sepsis patients leads to decreased bacterial clearance and accelerates the progression of sepsis disease. Quantification of PMN chemotaxis in sepsis patients can help characterize the immune health of sepsis patients. Microfluidic microarrays have been widely used for cell chemotaxis analysis because of the advantages of low reagent consumption, near-physiological environment, and visualization of the migration process. Currently, the study of PMN chemotaxis using microfluidic chips is mainly limited by the cumbersome cell separation operation and low throughput of microfluidic chips. In this paper, we first designed an inertial cell sorting chip to achieve label-free separation of the two major cell types by using the basic principle that leukocytes (mainly granulocytes, lymphocytes and monocytes) and erythrocytes move to different positions of the spiral microchannel when they move in the spiral microchannel under different strength of inertial force and Dean's resistance. Subsequently, in this paper, we designed a multi-channel cell migration chip and constructed a microfluidic PMN inertial label-free sorting and chemotaxis analysis platform. The inertial cell sorting chip separates leukocyte populations and then injects them into the multi-channel cell migration chip, which can complete the chemotaxis test of PMN to chemotactic peptide (fMLP) within 15 min. The remaining cells, such as monocytes with slow motility and lymphocytes that require pre-activation with proliferative culture, do not undergo significant chemotactic migration. The test results of sepsis patients ( n=6) and healthy volunteers ( n=3) recruited in this study showed that the chemotaxis index (CI) and migration velocity ( v) of PMN from sepsis patients were significantly weaker than those from healthy volunteers. In conclusion, the microfluidic PMN inertial label-free sorting and chemotaxis analysis platform constructed in this paper can be used as a new tool for cell label-free sorting and migration studies.

Abstract
Objective:To investigate the impact of time interval from symptoms onset to vestibular rehabilitation on the recovery of patients in the acute phase of vestibular neuritis. Methods:Thirty-one patients with vestibular neuritis treated in outpatient and inpatient settings from December 2019 to July 2021 were selected and randomly divided into vestibular rehabilitation group and general treatment group. The vestibular rehabilitation group was subdivided into early-intervention group (1-week after symptom onset) and late-intervention group (2-week after symptom onset) according to the interval from the onset to vestibular rehabilitation. The differences in DP, UW, VOR, DHI, BBS and SAS values at 1 month and 3 months after treatment were compared among early-intervention group(11 cases), late-intervention group (10 cases) and general treatment group(10 cases). Results:For patients in the vestibular rehabilitation group and the general treatment group, DP, UW, VOR gain, DHI score and SAS score were significantly different after treatment ( P<0.05) and no significant difference was found in BBS score (P>0.05 ). Pairwise comparisons between early-intervention and late-intervention group showed that the DP, UW and VOR gain were significantly different (P<0.05), while the score of DHI and SAS were not significantly different (P>0.05). Conclusion:Vestibular rehabilitation therapy can accelerate vestibular compensation, relieve vertigo symptoms and anxiety symptoms in patients with vestibular neuritis. It is better to be carried out within 1 week after symptom onset.

Abstract
OBJECTIVE To analyze the expression of immunoglobulin mucin molecule 3 (TIM-3) in epithelial ovarian cancer (EOC) and the effects of TIM-3 knockdown and overexpression on proliferation and migration of ovarian cancer cells. METHODS We analyzed TIM-3 expression in EOC and normal ovarian tissues using GEPIA database. We also detected TIM-3 expression levels in 82 surgical specimens of EOC and 18 specimens of normal ovarian tissues using immunohistochemistry, and analyzed the correlation of TIM-3 expression with clinicopathological parameters and survival outcomes of the patients. The expression of TIM-3 and Wnt1 mRNA in the tissues were detected using qRT-PCR. We constructed SKOV3 cell models of TIM-3 knockdown and overexpression and examined the changes in proliferation, apoptosis, migration and invasion of the cells using MTT assay, Annexin V-FITC/PI staining, scratch test and Transwell assay. The activity of Wnt/β-catenin pathway in the transfected was detected using dual luciferase reporter assay, and the mRNA levels of TCF-7, TCCFL-2 and CD44 were detected using qPCR. The protein expressions of MMP-9, CD44, Wnt1, β-catenin and E-cad in the transfected cells were detected with Western blotting. RESULTS The positive expression rate of TIM-3 was significantly higher in EOC tissues than in normal ovarian tissues (P < 0.05). The expression of TIM-3 was significantly correlated with FIGO stage, histological differentiation and lymph node metastasis, and was positively correlated with Wnt1 level (P < 0.05). In SKOV3 cells, TIM-3 knockdown significantly lowered the activity of Wnt/ β-catenin pathway, inhibited cell proliferation, migration and invasion, and promoted cell apoptosis. TIM-3 knockdown significantly down-regulated the mRNA levels of TCF-7, TCFL-2 and CD44 and the protein levels of MMP-9, CD44, Wnt1 and β-catenin, and significantly up-regulated the expression level of E-cad (P < 0.05). Overexpression of TIM-3 caused opposite effects in SKOV3 cells. CONCLUSION TIM-3 is highly expressed in EOC tissue to promote malignant behaviors of the tumor cells possibly by activating the Wnt/β-catenin signal pathway.

Abstract
Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.
