Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies. Based on the immunomodulatory capability of CAR-T cells, efforts have turned toward exploring their potential in treating autoimmune diseases. Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases, covering a range of subtypes such as systemic lupus erythematosus, multiple sclerosis, among others. CAR-T therapy holds promise in mitigating several shortcomings, including the indiscriminate suppression of the immune system by traditional immunosuppressants, and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints. By persisting and proliferating in vivo, CAR-T cells can offer a tailored and precise therapeutics. This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases, incorporating innovations well-studied in the field of hematological tumors, aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.

Objective To investigate the status and influencing factors of sleep in preterm infants at 1 month corrected age.Methods 130 preterm infants admitted to the NICU of 3 tertiary hospitals in Hubei Province were recruited as participants during May 2021 and March 2022.Sleep assessment of preterm infants was conducted at 1 month corrected age.Infants'sleep was assessed using the Brief Infant Sleep Questionnaire(BISQ).Multivariate linear regression model was used to analyze the influencing factors of sleep status(sleep latency,night awakenings,nocturnal sleep duration,daytime sleep duration,24 h sleep duration)of preterm infants.Results A total of 124 preterm infants completed the follow-up at 1 month corrected age.Multiple linear regression analysis showed that feeding patterns and sleep initiation patterns affected the sleep latency;gestational age,mechanical ventilation duration,maternal education level,and sleep initiation patterns were influencing factors of night awakenings;nocturnal sleep duration was influenced by mechanical ventilation duration and feeding patterns;daytime sleep duration and 24 h sleep duration were influenced by feeding patterns and maternal educational level.Conclusion The preterm infant sleep is influenced by gestational age,duration of mechanical ventilation,feeding patterns,maternal education level,and sleep initiation patterns.Neonatology staff should focus on the preterm infants discharged from NICU and develop targeted intervention plans based on the determined influencing factors to improve the sleep status of preterm infants.

Objective:To explore stereoscopic vision and its correlation with cognitive function in first-episode drug-na?ve patients diagnosed with schizophrenia (FNPS).Methods:A study was conducted from January 2019 to September 2020. A total of 146 FNPS, 124 patients with chronic schizophrenia (PCS) and 101 healthy controls (HCs) were recruited. Stereoscopic vision was evaluated by Titumus stereotests. Their clinical symptoms were assessed by positive and negative syndrome scale. Cognitive function was assessed by the repeatable battery for the assessment of neuropsychological status (RBANS). The differences in stereoscopic vision and cognitive function among the three groups were analyzed by analysis of covariance. The Spearman correlation and multiple regression analysis were used to identify the correlation between stereoscopic vision and clinical symptoms or cognitive function.Results:(1) There were significant differences in stereoscopic vision and cognitive function among the three groups ( P<0.05). After pairwise comparison, it was found that the stereoscopic vision and cognitive functions of FNPS group and PCS group were significantly different from HCs group. However, there were no significant differences in stereoscopic vision and cognitive function between FNPS and PCS groups. (2) Spearman correlation analysis showed that stereoscopic vision was not correlated with the severity of clinical symptoms in FNPS, but it was correlated with visuospatial score ( r=-0.193, P=0.019), language score ( r=-0.261, P=0.001), attention score ( r=-0.168, P=0.042), and RBANS total scores ( r=-0.236, P=0.004). Moreover, there was no correlation of stereoscopic vision with the severity of clinical symptoms or cognitive function in HCs and PCS. Further multiple linear regression showed the significant effect of stereoscopic vision on visuospatial score ( β=-0.213, P=0.011), language score ( β=-0.252, P=0.003), attention score ( β=-0.189, P=0.019), RBANS total score ( β=-0.235, P=0.003) in FNPS. Conclusions:FNPS and PCS show significant impairments in stereoscopic vision and cognitive function. Stereoscopic vision is closely correlated with cognitive function rather than the severity of clinical symptoms in FNPS.

Objective: To investigate the clinical value of laparoscopic peritoneal dialysis catheter implantation in peritoneal chemotherapy for gastric cancer with peritoneal metastasis. Methods: From January 2019 to June 2019, the clinical data of 6 patients diagnosed as gastric cancer with peritoneal metastasis were retrospectively analyzed in the Gastrointestinal Surgery Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine. Five were male and 1 was female. The median age was 69.5 (28-77) years. The median body mass index (BMI) was 22.8 (19.6-23.5). All procedures were performed under general anesthesia with endotracheal intubation. The patient′s body position and facility layout in the operating room were consistent with those of laparoscopic gastrectomy. The operator′s position: the main surgeon was located on the right side of the patient, the first assistant stood on the left side of the patient, and the scopist stood between the patient′s legs. Surgical procedure: (1) trocar location: three abdominal trocars was adopted, with one 12 mm umbilical port for the 30° laparoscope (point A). Location of the other two trocars was dependent on the procedure of exploration or biopsy as well as the two polyester cuff position of the peritoneal dialysis catheter: Usually one 5 mm port in the anterior midline 5 cm inferior to the umbilicus point was selected as point B to ensure that the distal end of the catheter could reach the Douglas pouch. The other 5 mm port was located in the right lower quadrant lateral to the umbilicus to establish the subcutaneous tunnel tract, and the proximal cuff was situated 2 cm away from the desired exit site (point C).(2) exploration of the abdominal cavity: a 30° laparoscope was inserted from 12 mm trocar below the umbilicus to explore the entire peritoneal cavity. The uterus and adnexa should be explored additionally for women. Once peritoneal metastasis was investigated and identified, primary laparoscopic peritoneal dialysis catheter implantation was performed so as to facilitate subsequent peritoneal chemotherapy. Ascites were collected for cytology in patients with ascites. (3) peritoneal dialysis catheter placement: the peritoneal dialysis catheter was introduced into the abdominal cavity from point A. Under the direct vision of laparoscopy, 2-0 absorbable ligature was reserved at the expected fixation point of the proximal cuff (point B) for the final knot closure. Non-traumatic graspers were used to pull the distal cuff of peritoneal dialysis catheter out of the abdominal cavity through point B. The 5-mm trocar was removed simultaneously, and the distal cuff was fixed between bilateral rectus sheaths at the anterior midline port site preperitoneally. To prevent subsequent ascites and chemotherapy fluid extravasation, the reserved crocheted wire was knotted. From point C the subcutaneous tunnel tract was created before the peritoneal steath towards the port site lateral to the umbilicus. Satisfactory catheter irrigation and outflow were then confirmed. Chemotherapy regimen after peritoneal dialysis catheterization: all patients began intraperitoneal chemotherapy on the second day after surgery. On the 1st and 8th day of each 3-weeks cycle, paclitaxel (20 mg/m²) was administered through peritoneal dialysis catheter, and paclitaxel (50 mg/m²) was injected intravenously. Meanwhile, S-1 was orally administered twice daily at a dose of 80 mg·m^-2·d^-1 for 14 consecutive days followed by 7-days rest. To observe the patients′ intraoperative and postoperative conditions. Results: All the procedures were performed successfully without intraoperative complications or conversion to laparotomy. No 30 day postoperative complications were observed. The median operative time was 33.5 (23-38) min. The median time to first flatus was 1(1-2) days, and the median postoperative hospital stay was 3 (3-4) days, without short-term complications within 30 days postoperatively. The last follow-up was up to July 10, 2019, and the patients were followed for 4(1-6) months. No ascites extravasation was observed and no death occurred in the 6 patients. There was no catheter obstruction or peritoneal fluid extravasation during and after chemotherapy. Conclusion Laparoscopic peritoneal dialysis catheter implantation was safe and feasible for patients with peritoneal metastasis of gastric cancer. The abdominal exploration, tumor staging and the abdominal chemotherapy device implantation can be completed simultaneously, which could simplify the surgical approach, improve the quality of life for patients and further propose a new direction for the development of abdominal chemotherapy.

Objective To determine the coagulation status as well as circulating levels of complement and inflammation markers in patients with chronic urticaria (CU) during acute attack and in remission,and to estimate the relationship of coagulant and anticoagulant factors as well as fibrinolytic markers with the development of chronic urticaira.Methods This study included 40 patients with CU (22 during acute attack and 18 in remission) and 40 healthy blood donors from the Guangzhou Blood Center.Venous blood samples were obtained from these subjects,and enzyme-linked immunosorbent assay (ELISA) was performed to measure the plasma levels of prothrombin fragrnent 1 +2 (F1 +2),tissue factor (TF),thrombomodulin (TM),high molecular weight kininogen (HMWK),tissue-type plasminogen activator (t-PA),C5a and serum levels of C3,C4,antistreptolysin O antibodies (ASO),rheumatoid factor (RF) and C-reactive protein (CRP).Erythrocyte sedimentation rate (ESR) was also determined in these patients.Comparisons of these parameters were carried out by using t test,and the correlation of these factors with CU was evaluated by using Spearman correlation coefficient.Results Compared with the healthy controls,the patients with CU showed significantly higher plasma levels of F1+2 and HMWK (both P ＜ 0.01),but lower levels of TF,TM and t-PA (all P ＜ 0.01).The plasma levels of F1 +2,HMWK,t-PA were significantly correlated with the symptom scores in patients with CU (r =0.81,P ＜ 0.01; r =-0.39,P ＜ 0.05; r =0.35,P ＜ 0.05).A significant increase was observed in the plasma concentration of F1 +2 in patients during acute attack compared with those in remission (P ＜ 0.01),whereas no significant differences were noted in the plasma levels of TF,TM,HMWK,t-PA,C5a,serum levels of C3,C4,ASO,RF and CRP or ESR between the two groups of patients (all P ＞ 0.05).Conclusions It seems that coagulation,anti-coagulation and fibrinolysis are all involved in the development of urticaria.There is an obvious difference in the plasma level of prothrombin F1 +2 between patients with CU during acute attack and in remission,suggesting that coagulation factors play a certain role in the initiation and progression of CU.

OBJECTIVETo investigate the expression pattern of resistin (RSTN) in skeletal muscle tissue and its influence on glycometabolism in rats with traumatic brain injury (TBI).

METHODSSeventy-eight SD rats were randomly divided into traumatic group (n=36), RSTN group (n=36) and sham operation group (n=6). Fluid percussion TBI model was developed in traumatic and RSTN groups and the latter received additional 1 mg RSTN antibody treatment for each rat. At respectively 12 h, 24 h, 72 h, 1 w, 2 w, and 4 w after operation, venous blood was collected and the right hind leg skeletal muscle tissue was sampled. We used real-time PCR to determine mRNA expression of RSTN in skeletal muscles, western blot to determine RSTN protein expression and ELISA to assess serum insulin as well as fasting blood glucose (FBG) levels. Calculation of the quantitative insulin sensitivity check index (Q value) was also conducted. The above mentioned indicators and their correction were statistically analyzed.

RESULTSCompared with sham operation group, the RSTN expression in the skeletal muscle as well as serum insulin and FBG levels revealed significant elevation (P<0.05), and reduced Q value (P<0.05) in traumatic group. Single factor linear correlation analysis showed a significant negative correlation between RSTN expression and Q values (P<0.001) in traumatic group.

CONCLUSIONThe expression of RSTN has been greatly increased in the muscular tissue of TBI rats and it was closely related to the index of glycometabolism. RSTN may play an important role in the process of insulin resistance after TBI.
