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 observe the efficacy of cosmetic suturing techniques combined with topical recombinant human basic fibroblast growth factor (rh-bFGF) in repairing facial trauma.Methods:A prospective study was conducted on 140 patients with facial trauma admitted to the Department of Burn and Plastic Surgery, Northern Jiangsu People＇s Hospital from January to December 2022. Patients were divided into two groups based on different treatment methods using a random number table method: treatment group (70 cases), including 38 males and 32 females aged 3 to 54 (23.1±8.2) years, received cosmetic suturing techniques combined with topical rh-bFGF for wound repair; control group (70 cases), including 36 males and 34 females aged 2 to 49 (22.3±7.5) years, only received cosmetic suturing techniques for wound repair. Patients were followed up 2 weeks post-surgery to evaluate wound healing quality. Patient satisfaction was assessed using the visual analogue scale (VAS). Six months post-surgery, scar conditions were evaluated using the Vancouver scar scale (VSS).Results:In the treatment group, 65 cases were directly sutured, and 5 cases were repaired with skin flaps, with a first-class healing rate of 100% (70/70). In the control group, 66 cases were directly sutured, and 4 cases were repaired with skin flaps, with a first-class healing rate of 91.4% (64/70). The first-class healing rate in the treatment group was higher than that in the control group, with a statistically significant difference ( P=0.037). Two weeks post-surgery, the VAS score for surgical satisfaction in the treatment group was (1.13±0.52) scores, which was lower than that in the control group (2.56±1.32) scores, with a statistically significant difference ( P<0.001). Six months post-surgery, the VSS score for the treatment group was (2.49±1.27) scores, which was lower than that in the control group (4.67±1.93) scores, with a statistically significant difference ( P<0.001). Conclusions:In repairing facial trauma, the combination of cosmetic suturing techniques and topical rh-bFGF can improve wound healing quality, reduce wound scarring, and enhance patient satisfaction with surgery.

Objective:To compare the clinical features, X-ray, CT, MRI imaging findings of C 3, 4 single segment cervical spondylotic myelopathy among the elderly group, the middle-aged group and the young group. Methods:The medical records and imaging data of 51 cases of single segment C 3, 4 cervical spondylotic myelopathy treated from January 2017 to December 2021 were retrospectively reviewed. There were 10 cases in the young group, including 8 males and 2 females, 23-44 years, with an average age of 35.8±7.62 years; 14 cases in the middle-aged group, including 9 males and 5 females, 48-60 years, with an average age of 53.21±4.14 years; 27 cases in the elderly group, including 24 males and 3 females, 61-84 years, with an average age of 68.04±5.97 years. Based on the medical record data, the differences in clinical manifestations among the three groups (initial symptoms, symptom distribution, pathological sign distribution and JOA score) were analyzed. Based on the imaging data, the static factors (cervical osteophyte, alignment and thickness of cervical ligamentum flavum) and dynamic factors [overall cervical range of motion (ROM), individual segment cervical ROM, cervical instability and cervical nuchal ligament calcification] were analyzed. Anatomical factors (C 2-C 7 Cobb angle, C 4-C 7 Cobb angle, C 3 vertebral canal diameter, C 4 vertebral diameter, C 3 Pavlov ratio, C 4 Pavlov ratio) and spinal cord compression (spinal cord signal, compression position and compression nature) were also analyzed. Results:There were no statistically significant difference in gender distribution and height in three groups of patients ( P>0.05). In terms of clinical manifestations, there were statistically significant differences among the three groups in initial symptoms and chief symptoms ( P<0.05). The elderly group had upper limb weakness as the first symptom, lower limb weakness and abnormal gait as the chief complaint; the middle-aged group had upper limb numbness as the first symptom, upper limb numbness and weakness as the chief complaint; the young group had upper limb pain as the first symptom, upper limb numbness as the chief complaint. There were statistically significant differences in Hoffmann sign and Babinski sign among the three groups ( P<0.05). Hoffmann sign and Babinski sign were more common in the elderly group than in the young group ( P<0.05). There were significant differences among the three groups in total JOA score, JOA score of motor and lower limb motor JOA ( P<0.05). The total JOA score in the elderly group was lower than that in the young group ( P<0.05), especially for motor JOA score ( P<0.05), and lower limb motor JOA score ( P<0.05). There were no significant differences in first symptoms distribution, symptoms distribution, biceps reflex, triceps reflex, radial reflex or knee tendon reflex among the three groups ( P>0.05). In terms of static factors, there was significant difference in alignment and thickness of cervical ligamentum flavum among the three groups (P<0.05). The elderly group was more prone to slip than the young and middle aged groups ( P<0.05). The thickness of ligamentum flavum in the elderly group (2.18±0.68 mm) was thicker than that in the young group (1.60±0.30 mm) and the middle-elderly group (1.60±0.62 mm) ( P<0.05). There was no significant difference in cervical osteophyte among the three groups ( P>0.05). In terms of dynamic factors, there were statistically significant difference in C 3-C 7 ROM, C 4-C 7 ROM, C 3, 4 ROM and ossification of nuchal ligament among the three groups ( P<0.05). In the elderly group, C 3-C 7 ROM (22.18°) was larger than that in the young group (21.27°) ( P<0.05), while in the elderly group C 4-C 7 ROM (9.60°) was smaller than that in the young group (14.19°) ( P<0.05). In the elderly group, C 3, 4 ROM (15.30°) was larger than that in the young group (9.97°) ( P<0.05), and the elderly group was more prone to nuchal ligament calcification than the young and the middle-elderly group ( P<0.05). There were no significant difference among the three groups in C 4, 5 ROM, C 5, 6 ROM, C 6, 7 ROM or cervical instability ( P>0.05). For spinal cord compression, there were statistically significant differences among the three groups in the compression nature, compression location and MRI T2WI spinal cord signal ( P<0.05). The elderly group was more prone to anterior and posterior bony compression. The elderly group was more likely to show high signal intensity on spinal cord MRI T2WI than the young group ( P<0.05). For anatomical factors, there were statistically significant differences in C 2-C 7 Cobb, C 3 vertebral diameter and C 3 Pavolv among the three groups ( P<0.05) . The C 2-C 7 Cobb of the elderly group (21.06°) was larger than that of the young group (16.45°) ( P<0.05), and the C 3 diameter of the elderly group (9.61±0.33 mm) was smaller than that of the young group (10.38±1.19 mm) ( P<0.05). The C 3 Pavolv of the elderly group (0.52±0.03) was lower than that of the young group (0.59±0.11) ( P<0.05). In the presence of lordosis, C 4-C 7 Cobb in the elderly group (4.96°±4.05°) was smaller than that in the young group (12.42°±4.83°) and the middle-aged group (10.07°±6.14°) ( P<0.05). In the presence of kyphosis, C 4-C 7 Cobb in the elderly group (4.02°±1.19°) was larger than that in the young group (0.06°±0.01°) and the middle-aged group (1.83°±0.93°) ( P<0.05). There were no significant differences in C 3-C 7 Cobb, C 4 vertebral diameter or C 4 Pavolv among the three groups ( P>0.05). Conclusion:Young patients mostly have anteriorly soft compression of disc herniation, and most of them complain of neck and upper limb pain, while spinal cord compression and clinical manifestations are relatively mild. For the elderly patients, most of them have C 3 retrolisthesis, with the pinching type bony compression of spinal cord from both anteriorly and posteriorly, and their complaints are usually upper limb numbness, mostly accompanied by radiographically severe spinal cord compression and clinically gait abnormalities. In the middle-aged patients, the rigid compression of anterior calcified disc herniation is the main reason, and the numbness of upper limb is the chief complain.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

Heterotopic ossification is a rare complication of burns, and its incidence and risk factors are still unclear. Through summarizing the literature on heterotopic ossification caused by burns at home and abroad, the author searched for the risk factors of heterotopic ossification after burn and the new progress of its prevention and treatment. It was realized that the size, depth and healing time of burn wounds were related to heterotopic ossification; the nonsteroidal anti-inflammatory drugs, radiation therapy, and their combination therapy can be used for the prevention of heterotopic ossification; surgery is an effective means of treating heterotopic ossification.

Immune checkpoint inhibitors are able to reactivate the immune system therefore enhance the anti-tumor effects. However, over-activated T cells may induce immune related adverse events (irAEs). Hematological irAEs are rarely reported, which mainly represent as mono-lineage cytopenia or pancytopenia, including autoimmune hemolytic anemia (AIHA), immune thrombocytopenia (ITP), neutropenia and aplastic anemia, sometimes even lethal, such as hemophagocytic lymphohistiocytosis. The clinical manifestations of hematological irAEs will be summarized and recommendations of diagnosis and treatment are proposed.

Immune checkpoint inhibitors (ICIs) have made remarkable breakthroughs in cancer treatment. However, the widely use of ICIs is associated with a spectrum of immune-related adverse events (irAEs). These adverse events can affect any organ system. In this article, we have made a systemic review about the clinical characteristics of rheumatic irAEs, and also summarized irAEs in patients with pre-exsiting rheumatic disease. We also focus on the management of rheumatic irAEs.

Immunotherapy for malignant tumors is a hot spot in current research and treatment of cancer. The activation of programmed cell death receptor-1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA)-4 relevant signaling pathway can inhibit the activation of T lymphocytes. Tumor cells can achieve immune escape by activating this signaling pathway. By inhibiting this signaling pathway, immune-checkpoint inhibitors (ICIs) activate T lymphocytes to clear the tumor cells. Therefore, the adverse effects of ICIs are mainly immune-related adverse events (irAEs). The digestive system, including gastrointestinal tract and liver are vital organs of digestion and absorption, metabolism and detoxification, as well as important immune related organs, which are the commonly affected system of irAEs. This review separately explains the incidence, clinical features, diagnosis and treatment of liver and gastrointestinal adverse events in ICIs.

The increasing use of target therapy and immunocheckpoint inhibitors in cancers has brought new hope of survival to patients with advanced tumors. However, more and more adverse side-effects and toxicities of these medications had been reported, affect almost all human organs including the eye. These adverse effects may affect the entire ocular tissues, like eyelid, eye lashes, conjunctiva, cornea, uvea, retina, optic nerve and so on, which are always been ignored by patients and doctors. In this paper we will summarize the characteristics of the related ocular diseases and give our advice on how to diagnose and manage these diseases.

As a new type of anti-cancer drugs, immune checkpoint inhibitors (ICIs) have shown remarkable therapeutic effects in many malignant tumors. By virtue of their targets and mechanisms of action, ICIs can cause autoimmune and inflammatory effects, termed immune-related adverse events (irAEs). Unlike traditional therapies, irAEs are latent and unstable. Severe adverse reactions will force patients to discontinue treatment and even affect their survival. Therefore, with the wide application of ICIs in clinical practice, clinicians need to fully understand the possible adverse reactions of such drugs and appropriate treatment strategies, in order to improve the survival rate and treatment effect of patients receiving ICIs. In this article, we review the incidence, clinical features, diagnosis and treatment of immune-related endocrine events that may occur with administration of ICIs.
