Diffuse large B-cell lymphoma (DLBCL) is a common, highly aggressive and heterogeneous hematologic malignancy in adults. Patients with DLBCL have substantially differences in molecular biological characteristics, clinical manifestations, and prognosis. Increasing evidence shows that the tumor microenvironment plays an important role in the occurrence and development of DLBCL. CD47, an integrin related protein, is overexpressed in DLBCL cells and plays a key role in immune escape of lymphoma. This work reviews the research progress of CD47 in DLBCL TME in terms of CD47-related signal pathway, CD47 role in DLBCL TME, and therapeutic strategies targeting CD47 in DLBCL TME.

Objective:To investigate the value of pulse oxygen saturation (SpO 2) monitoring in predicting children with moderate-to-severe obstructive sleep apnea (OSA). Methods:It was a retrospective study involving 341 children with snoring during nighttime sleep who had visited the Children′s Hospital of Soochow University from June 2017 to November 2020 and monitored for polysomnography (PSG) and SpO 2.The SpO 2 parameters mainly included oxygen desaturation index (ODI), oxygen desaturation index ≥3% (ODI3), oxygen desaturation index ≥4% (ODI4), mean pulse blood oxygen saturation (MSpO 2), lowest pulse blood oxygen saturation (LSpO 2), cumulative time spent with blood oxygen saturation below 95%, 92% and 90%(T95, T92 and T90). According to obstructive sleep apnea hypopnea index (OAHI), patients were divided into the snoring and mild OSA group (OAHI≤5 times/h) and moderate-to-severe OSA group (OAHI>5 times/h). Differences in SpO 2 parameters were compared between groups using the Chi- square test and Mann- Whitney U test. Spearman correlation analysis was used to analyze the correlation between SpO 2 parameters and OAHI in all children.The SpO 2 parameters were included in the Logistic regression model.Receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficiency of SpO 2 parameters on moderate-to-severe OSA. Results:A total of 341 patients were recruited, including 206 male and 135 female patients with the mean age, body mass index (BMI) and OAHI of 6.0 (4.0, 7.5) years, 16.2 (15.1, 18.0) kg/m 2 and 0.6 (0.1, 3.0) times /h, respectively.There were 283(83.0%) and 58 (17.0%) patients in the snoring and mild OSA group and moderate-to-severe OSA group.The ODI3[0.7 (0.3, 1.4) times/h vs.7.7 (4.4, 12.8) times/h], ODI4[0.4 (0.1, 0.8) times/h vs.5.3 (2.7, 9.1) times/h], T95[1.4 (0.3, 5.3) min vs.13.7 (7.0, 33.5) min], T92[0.1 (0, 0.5) min vs.1.8 (0.9, 6.0) min] and T90[0 (0, 0.1) min vs.0.6 (0.2, 2.2) min] were significantly lower in the snoring and mild OSA group than those of moderate-to-severe group, while LSpO 2[91.0 (89.0, 93.0)% vs.86.5 (82.0, 88.0)%] and MSpO 2[ 97.0 (97.0, 98.0)% vs.96.0 (96.0, 97.0)%] were significantly higher(all P<0.001). All SpO 2 parameters were significantly correlated with OAHI (all P<0.001), and the correlation coefficient between ODI3 and OAHI was 0.660.ODI3 was an independent predictor of moderate-to-severe OSA ( OR=3.117, 95% CI: 1.635-5.945, P=0.001). The area under the ROC curve of ODI3 in predicting the moderate-to-severe OSA was 0.957, and the cut-off value of 3.45 times/h and specificity of 95.4%.MSpO 2 was an independent predictor of moderate-to-severe OSA ( OR=2.917, 95% CI: 1.589-5.354, P=0.001). Conclusions:ODI3 can be used to predict the moderate-to-severe OSA in children.

Objective:To study the impacts of pre-pregnancy body mass index (BMI), gestational diabetes mellitus (GDM) and gestational weight gain (GWG) on perinatal outcomes and mode of delivery.Methods:From November 2016 to December 2017, single-pregnancy women in early pregnancy (<13 weeks) regularly checked-up at our hospital were enrolled in this prospective cohort study and followed up until delivery. They were assigned into four groups according to pre-pregnancy BMI: obese group (≥28.0 kg/m 2), overweight group(24.0-<28.0 kg/m 2), normal group (18.5-<24.0 kg/m 2) and underweight group(<18.5 kg/m 2). A 75-g oral glucose tolerance test was performed at 24-28 weeks of pregnancy to screen for GDM. The optimal GWG was 11.0-16.0 kg for underweight group, 8.0-14.0 kg for normal group, 7.0-11.0 kg for overweight group and 5.0-9.0 kg for obesity group. The effects of pre-pregnancy BMI, GDM and GWG on perinatal outcomes and delivery mode were evaluated using multivariate logistic regression methods. Results:A total of 802 pregnant women were included. The incidences of pre-pregnancy overweight and obesity were 21.8% and 8.9%, respectively. The incidence of GDM was 14.1%. 57.2% of the participants experienced excessive GWG. The incidences of macrosomia, low birth weight and premature birth were 7.1%, 2.7% and 2.2%, respectively. The incidence of Cesarean delivery (C-section) was 37.7%. Pre-pregnancy obesity [adjusted odds ratio ( AOR)=4.355, 95% confidence interval ( CI) 1.900-9.980] and excessive GWG ( AOR=3.799, 95% CI 1.796-8.034) were independent risk factors for macrosomia. Excessive GWG was a protective factor for low birth weight ( AOR=0.279, 95% CI 0.084-0.928) and inadequate GWG was a risk factor for low birth weight ( AOR=10.954, 95% CI 3.594-33.382) and premature birth ( AOR=8.796, 95% CI 2.628-29.438). Compared with the normal group, overweight group had an increased risk of C-section ( AOR=1.817, 95% CI 1.119-2.949). Compared with pregnant women without pre-pregnancy overweight/obesity, GDM nor excessive GWG, any combination of two of the above-mentioned three factors increased the risks of macrosomia ( AOR=3.908, 95% CI 1.630-9.370) and C-section ( AOR=2.269, 95% CI 1.325-3.886). The risks of macrosomia and C-section were the highest when all three factors existed. Conclusions:Pre-pregnancy obesity and excessive GWG are independent risk factors for macrosomia and pre-pregnancy overweight is a risk factor of C-section. Exposure to any two of the three factors (pre-pregnancy overweight/obesity, GDM and excessive GWG) increases risks of macrosomia and C-section and the highest risk is observed when all three factors are present.

Chicoric acid， a hydroxycinnamic acid with the molecular formula C₂₂H₁₈O₁₂， is an important active ingredient in Taraxacum mongolicum， Echinacea purpurea， Cichorium intybus and other natural plants， and it helps plants protect themselves from insects and infection from viruses， bacteria， fungi， and nematodes. Modern pharmacological research suggests that chicoric acid has significant bioactivities such as anti-inflammatory， antioxidant， immune-regulating， antibacterial， antiviral and anti-tumor properties. The first reported bioactivity of chicoric acid is its inhibitory effect on human immunodeficiency virus （HIV）. With the development and application of molecular biology and related technologies， the inhibitory activities of chicoric acid on other viruses as well as its mechanism of action have been frequently reported. Another study indicates that chicoric acid has significant inhibitory effects on different pathogenic bacteria. This paper summarized the research progress on the antiviral and antibacterial effects of chicoric acid through a comprehensive review of relevant literature in China and abroad in the past 20 years. Studies have shown that chicoric acid has significant inhibitory activities against various viruses such as HIV， hepatitis B virus （HBV）， respiratory syncytial virus （RSV）， and herpes simplex virus （HSV）， as well as different pathogenic bacteria such as Staphylococcus aureus， Yersinia enterocolitica and Mycobacterium tuberculosis. This study is expected to provide references for in-depth research on chicoric acid against pathogenic microorganisms and antiviral and antibacterial study of traditional Chinese medicine.

Objective:This study aimed to investigate the effect of short-term antipsychotic medication treatment of patients with schizophrenia on the effect of the thalamocortical resting-state functional connectivity.Methods:83 first-episode drug-na?ve schizophrenia patients and 117 matched healthy controls participated in the present study. The study collected resting-state fMRI data before and after the patients received short-term antipsychotics to assess the changes in the thalamocortical circuits and clinical symptoms. The directional interactions between the thalamus and other brain regions were investigated using a standard seed-based whole-brain correlation by choosing the bilateral thalamus as the seeds. Spearman′s correlation analysis was carried out between the change of abnormal functional connectivity and improved clinical symptoms in patients.Results:Compared with the healthy controls, schizophrenia patients showed decreased thalamic-prefrontal functional connectivity (including the middle frontal cortex, inferior frontal cortex, middle cingulate cortex, posterior cingulate cortex, and inferior parietal lobe, all P<0.05, FDR corrected) and increased thalamic-sensorimotor functional connectivity(including the precentral gyrus, superior temporal cortex, middle temporal cortex, inferior temporal cortex, parahippocampus, and middle occipital cortex, all P<0.05, FDR corrected)at baseline. After short-term antipsychotic treatment, the thalamic-prefrontal hypo-connectivity was significantly enhanced, and the thalamic-sensorimotor hyper-connectivity was significantly decreased. Furthermore, the changes of abnormal functional connectivity were correlated significantly with the PANSS total score changes improvement ( r=0.435, P=0.014; r=0.394, P=0.028,uncorrected). Conclusions:The present study replicates previous findings that the abnormalities of thalamocortical circuits in schizophrenia are characterized by thalamic-prefrontal hypoconnectivity and thalamic-sensorimotor hyperconnectivity. Moreover, short-term antipsychotic treatment partly improves thalamocortical abnormalities, which further relates to clinical symptom relief; Restoring of abnormal thalamocortical circuits plays an important role in the early treatment of schizophrenia.

Objective:To observe the local reactions and efficacy of CD19 CAR-T therapy in recurrence/refractory B-cell non-Hodgkin's lymphoma (R/R NHL) patients with >7.5 cm lesions.Methods:32 R/R NHL patients with >7.5 cm lesions were enrolled and injected with CD19 CAR-T cells. Flow cytometry was used to detect and observe the amplification of CD19 CAR-T cells in vivo. Enzyme-linked immunosorbent assay (ELISA) was used to detect cytokines in peripheral blood of patients. The side effects of CD19 CAR-T cell therapy included systemic side effects and local reactions of tumor. The local side effects were observed by Ultrasound, Computed tomography and Magnetic resonance imaging. Treatment options included glucocorticoid, interleukin-6 antibody and drainage of exudate. Overall response rate (ORR) and overall survival rate (OS) were observed.Results:①Among the 32 patients, CR (40.63%) , PR (31.25%) and ORR (71.88%) were 13, 10 and 23, respectively. ②In all 23 patients received ORR, 13 patients had grade 1-2 CRS, while 10 patients had grade 3-4 CRS. All the 9 patients in the SD+PD group had grade 1-2 CRS ( P=0.030) . ③A total of 15 patients with tumor local reactions, included 9 patients with CR, 5 patients with PR and 1 patient with SD. The local reactions of the tumor included that the diameter of the superficial lesions increased with redness, swelling and heat pain. The deep lesions presented abdominal pain, abdominal distension, suffocation and local pain, and burning of the tumor. The deep lesions were enlarged or accompanied by local edema. The local exudative lesions were found in the abdominal cavity and pleural cavity. ④ Peak proportion of CD19 CAR-T cells in ORR group was higher than that of in SD+PD group[16.8% (5.3%-48.2%) vs 2.9% (1.5%-5.7%) , z=-4.297, P<0.001]. The peak proportion of CD19 CAR-T cells in ORR group with local reactions was higher than that of in patients without local reactions [22.2% (10.5%-48.2%) vs 12.6% (5.3%-21.6%) , z=-3.213, P=0.001]. The peak proportion of CD19 CAR-T cells in multiple lesion group was higher than that of in single lesion group [35.8% (1.5%-48.2%) vs 16.8% (10.5%-18.5%) , z=-2.023, P=0.040]. ⑤Occurrence of local reactions and tumor shrinkage time were both delayed compared with systemic side effects. ⑥In the ORR group, the OS of patients with tumor local reactions was longer than that of patients without tumor local reactions, but there was no difference in the two groups (75% vs 34.6%, P=0.169) . Conclusions:CD19 CAR-T cell therapy in R/R NHL patients with >7.5 cm lesions might cause tumor local reactions later than systemic side effects.Clinicaltrial::ChiCTR1800018059

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.

Objective:To establish a predictive model of lateral lymph node metastasis in patients with papillary thyroid carcinoma(PTC), and further to compare the diagnostic efficiency of this model with the suspected abnormal lymph node thyroglobulin in fine-needle aspirate fluid (FNA-Tg) for lateral lymph node metastasis.Methods:The preoperative clinical and ultrasonographic data of 110 patients (257 lymph nodes) who underwent PTC cervical lymph node dissection were retrospectively analyzed. According to the postoperative pathological results, they were divided into lateral lymph node metastasis and non-metastasis group. Regression analysis was used to screen out independent risk factors affecting lateral lymph node metastasis and establish a predictive model. The ROC curve was used to evaluate the diagnostic efficacy and the best diagnostic cut-off point.Results:Prediction model: Logit( P)=-2.987+ 2.189(S/L ratio of lymph nodes)+ 1.748(hilum absent)+ 2.030(hyperechoic)+ 1.849(vascular abnormalities). The sensitivity, specificity, accuracy and AUC of the prediction model in the diagnosis of lateral lymph node metastasis were 92.1%, 83.9%, 87.9% and 0.929, respectively. The Homser-Lemeshow goodness of fit test showed that the Logistic model has a good fitting effect. The sensitivity, specificity, accuracy, and AUC of FNA-Tg in the diagnosis of lateral lymph node metastasis were 87.4%, 95.4%, 90.3% and 0.968, respectively. The sensitivity, specificity, accuracy, and AUC of the combined diagnosis of the predictive model and FNA-Tg were 92.9%, 96.9%, 94.2% and 0.989, respectively. Conclusions:The model has a good predictive value for PTC cervical lymph node metastasis. Combined with FNA-Tg, it can improve its diagnostic efficiency and provide more valuable information for the decision-making of clinical surgical procedures.
