Corneal transplantation is an effective treatment for corneal blindness, and it is the only hope for patients with corneal blindness. Cornea has no blood vessels and no lymphatic vessels, which is called immune privilege organ, so the success rate of corneal transplantation is significantly higher than that of other organ transplantation, but the rejection reaction after corneal transplantation is still the main reason for the failure of corneal transplantation. The directional movement of immune cells to lymphoid tissue and inflammatory sites is the mainly immune response after organ transplantation. And the regulatory T cells(Treg)play a key role in immune regulation, which can induce immune tolerance by regulating and inhibiting the activation of effector T cells and reduce the rejection reaction after corneal transplantation. In addition, this review also discussed the effectiveness of applying cordyceps sinensis extract FTY720 to enhance the function of Treg. Based on this, we briefly reviewed the sources, mechanism of action and treatment of Treg after corneal transplantation, so as to provide some reference for the subsequent clinical application transformation and basic research.

Objective To evaluate the early imaging characteristics and function of bladder wall reconstruction neourethra(BWN)after robot-assisted laparoscopic prostatectomy(RALP)for prostate cancer with magnetic resonance imaging(MRI)and voiding cystourethrography(VCUG).Methods A total of 36 patients who underwent RALP using BWN technique at Taizhou People's Hospital during Mar.2021 and Jun.2023 were enrolled.Postoperative MRI was used to measure the length,wall thickness,and lumen shape of the new urethra.The morphology of the new urethra in 19 patients was observed under VCUG during the storage phase,voiding phase,and interrupted voiding phase.Results The patients'median age was 73.00 years(range:68.00 to 76.25),the prostate volume was(45.01±7.18)cm3,and the median total prostate-specific antigen(tPSA)level was 10.77 ng/mL(range:7.30 to 14.86).Two patients were classified as T1 stage,25 as T2,and 9 as T3.Gleason scores were ≤6 in 7 patients and ≥8 in 8 patients.Risk classification was low risk in 2 patients and high risk in 8 patients.Postoperatively,urinary control rates at 1,3,and 6 months were 91.67％,97.22％,and 100％,respectively.MRI revealed a median new urethra length of 15.13 mm(range:12.71 to 20.26)and a median wall thickness of 6.84 mm(range:6.18 to 8.20).The urethral lumen had a complete muscular layer and mucosal layer,which appeared petal-like.In patients with urinary incontinence,residual urine was visible in the new urethra and at the anastomosis site.Of the 19 patients who underwent VCUG,16 could close the new urethra during the storage and interrupted voiding phases,and open it during the voiding phase;3 could not close it well during the storage and interrupted voiding phases.Conclusion MRI and VCUG clearly demonstrate that the BWN technique can successfully create a new urethra with good functionality,which helps improve urinary control after RALP for prostate cancer.

Objective:To explore effect of Glioma-associated oncogene family zinc finger 1(GLI1)on hypoxia induced trans-formation of NR8383 to M1 phenotype and development of pulmonary hypertension(PH).Methods:Fifteen adult male Wistar rats were randomly divided into control group,hypoxia PH model group and hypoxic PH with GANT61 treatment group,with 5 rats in each group.PH related indexes of rats were detected by small animal ultrasound and right cardiac catheter experiment to determine effect of GLI1 specific inhibitor GANT61 on progression of PH.Pulmonary arterial thickness was measured by HE staining.α-SMA and M1 polarization markers TNF-α and IL-1β expressions were determined by immunohistochemistry.M1 polarization markers CD86 and TNF-α expressions were determined by immunofluorescence.GLI1 expression and NF-κB protein were detected by Western blot.mRNA expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 were detected by qRT-PCR.CHIP-PCR verified that GLI1 regulates NF-κB promoter activity.IL-12 content was detected by ELISA.Rat pulmonary artery smooth muscle cells proliferation was detected by CCK-8.Results:GLI1 inhibitor GANT61 could alleviate symptoms of PH in hypoxic rats(P<0.05).Compared with hypoxic group,inhibition of GLI1 reduced expressions of TNF-α and IL-1β in rat lung tissue(P<0.05).In cell experiments,hypoxia induced M1 polarization of NR8383 by up-regulating GLI1 to activate NF-κB pathway,GLI1 overexpression increased expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 in M1 macrophages(P<0.05).NR8383 culture supernatants could stimulate pulmonary artery smooth muscle cell proliferation(P<0.05)and contribute to development of PH.Conclusion:Hypoxia activates NF-κB pathway by up-regulating GLI1 to induce M1 polarization of macrophages contributes to development of PH.

Neuromyelitis optica spectrum disorders (NMOSD) are a group of autoimmune-mediated inflammatory demyelinating diseases of the central nervous system, characterized by optic nerve and spinal cord lesions, with high chance of recurrence and disability. Disease-modifying therapy, including immunosuppressants, monoclonal antibodies, stem cell transplantation etc., is the key to prevent recurrence. This article made a systematic review about the sequential treatment or prognosis of NMOSD by searching for the related articles published on PubMed from 2017 to 2022 to provide recommendations and references for disease-modifying therapy of NMOSD.
