Immune checkpoint inhibitors are members of a class of immune-suppressive molecules that regulate the strength and range of immune responses to avoid normal tissue damage. However, immune checkpoint activity can be stimulated by tumors to es-cape immune surveillance. To elicit anti-tumor effects, immune checkpoint inhibitors can promote the activation of T cells by blocking immune checkpoint proteins. Therefore, these inhibitors can be efficiently and safely used to treat solid tumors. Although the clinical usage of these inhibitors is in the initial stage, they have exhibited good efficacy and safety in lymphoma treatment. This review sum-marizes the biological activities of CTLA-4, PD-1, and PD-L1 and the application of antibodies as drugs for lymphoma treatment.

Objective:To investigate the clinical features and treatment outcome of Kallmann syndrome(KS) caused by fibroblast growth factor receptor-1(FGFR1) gene mutation in 4 patients.Methods:Targeted next-generation sequencing(NGS) was performed on thirty KS and normosmic idiopathic hypogonadotropic hypogonadism(nIHH) patients. FGFR1 mutation was identified in four KS patients. The clinical data, laboratory and imaging examinations, and treatment outcome were retrospectively analyzed.Results:Four male patients, aging from 11 to 22 years old, presented as micropenis, and with olfactory dysfunction. Among them, two had history of cryptorchidism, three had history of cleft lip and palate repair surgery. The most severe patient presented with short stature, left microtia and dental agenesis. FGFR1 heterozygous mutation was identified in all four patients, two were point mutation(p.Y374X; p. E670K), and the other was frameshift mutation(p.S346Yfs*61; p.S723*fs*1). One patient, who started treatment of the pulsatile GnRH pump during his youth, succeeded in having two babies.Conclusion:Patients with Kallmann syndrome caused by FGFR1 mutation presents complex clinical manifestations. Besides dysosmia, micropenis, microrchidia, and delayed pubertal development are the main clinical manifestations in male patients. Symptoms such as cleft lip and palate are helpful for early recognition. Genotyping analysis is crucial to confirm the diagnosis. The pulsatile GnRH pump can produce satisfactory therapeutic effect, but the age of initiating therapy should be carefully considered.

Chinese Journal of Endocrinology and Metabolism 2022;38(2):165-169
Steroidogenic factor-1 (SF-1, NR5A1) is a transcription factor that plays a key role in the development of gonad and adrenal gland. NR5A1 gene mutation is one of the common causes of disorders of sex development(DSD). Heterozygous mutations of NR5A1 gene accounts for the majority of reported cases with various phenotyre. Early reported cases manifested with varying degrees of 46, XY gonadal dysplasia, whereas NR5A1 mutation was revealed to be related with the phenotypes of azoospermia in men and premature ovarian insufficiency in women recently. Adrenocortical insufficiency is absent in most cases. The heterogeneity of the clinical phenotype is considered resulting from the functional impact of different gene mutations on transcriptional activity, dose effect of downstream target gene(such as SOX9)and the genetic background of oligogenic mutation, etc. The process and regulation of gonadal development might be understood comprehensively by investigating the genotype and related phenotype of NR5A1.

Objective:To explore the application value of guide tube fenestration and drainage technology in intracranial artery stenting surgery.Methods:A total of 120 patients with symptomatic intracranial atherosclerotic stenosis admitted to the Xingtai Third Hospital from January 2021 to December 2022 were selected and randomly divided into an observation group ( n=60) and a control group ( n=60). Both groups were treated with intracranial artery stenting, with the observation group receiving guidance catheterization and window opening technique during the surgery. Two groups of surgeries were observed and compared: the degree of vascular stenosis before and after surgery, the Montreal Cognitive Assessment Scale (MoCA) scores before and one month after surgery, intraoperative complications, and prognosis. Results:The surgical time and catheter placement time in the observation group were (110.20±23.32)minutes and (11.32±2.01)minutes, respectively, which were significantly shorter than those in the control group (all P<0.05). The stent placement rate and operation success rate in the observation group were 95.00% and 96.67%, respectively, significantly higher than those in the control group (all P<0.05). The degree of postoperative vascular stenosis in the observation group was (32.29±7.11)%, significantly milder than that in the control group [(44.43±8.15)%, P<0.05]. One month after surgery, the MoCA scores of both groups improved significantly compared to before surgery (all P<0.05), and there was no statistically significant difference between the groups ( P>0.05). There was no statistically significant difference in the incidence of collateral circulation occlusion and vascular rupture between the two groups (all P>0.05). During the follow-up period, there was no statistically significant difference in the incidence of restenosis, intracranial hemorrhage, and recurrent ischemic stroke between the observation group and the control group (all P>0.05); The good prognosis rate of the observation group was 73.33%, significantly higher than that of the control group (53.33%, P<0.05). Conclusions:The application of guided catheter fenestration technique in intracranial artery stenting has good value, which is beneficial for improving the stent placement rate and operation success rate, and improving the degree of vascular stenosis.

Objective:To investigate methods of molecular diagnosis and clinical features of 46, XY disorders of sexual development(DSD).Methods:A total of 206 cases of 46, XY DSD patients, who visited the Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine, from July 2009 to June 2021, underwent AA chip based on multiplex PCR and probe-capture-targeted next-generation sequencing. Clinical features of patients with genetic diagnosis were analyzed.Results:Among 206 patients, the diagnostic rate of patients with micropenis, hypospadias and cryptorchidism was the highest, up to 75.28%. Almost all patients had different degrees of undermasculinized external genitalia. The most frequent phenotype was micropenis with hypospadias(87.25%). Only one gene variant was detected in 81 patients(39.32%), multiple genetic variants were detected in 104 patients(50.49%), and no gene variant was identified in 21 patients(10.19%). 107 patients had definite genetic diagnosis, with a diagnostic rate of 51.94% by adding the pathogenic and likely pathogenic ratios following the American College of Medical Genetics and Genomics(ACMG) guidelines, including 40 patients of steroid 5α-reductase type 2(SRD5A2) variants(37.38%), 36 patients of androgen receptor(AR) variants(33.64%), 13 patients of steroidogenic factor 1(NR5A1) variants(16.82%), 6 patients of 17β-hydroxysteroid dehydrogenases 3(HSD17B3) variants(5.61%), 2 patients of 17α-hydroxylase/17, 20-lyase enzyme(CYP17A1), Wilms′ tumor 1(WT1) and GATA binding protein 4(GATA4) variants(1.87%), and one patient of luteinizing hormone receptor(LHCGR) variant(0.93%). Gynecomastia was found in 29 of 81 postpubertal patients, of which 25(86.21%) had AR variants.Conclusions:46, XY DSD presents complex clinical manifestations and molecular etiologies. Targeted nextgeneration sequencing has the advantages of high throughput, high efficiency and low cost, which has a high value especially in etiological diagnosis of 46, XY DSD with large genetic heterogeneity.
