Objective:To investigate the clinical phenotype and genetic variation of Basel-Vanagaite-Smirin-Yosef syndrome (BVSYS), and to enhance clinicians′ knowledge of the disease.Methods:The clinical data of a child with BVSYS admitted to the Department of Neurological Rehabilitation, Qingdao Women and Children′s Hospital Affiliated to Qingdao University in February 2023 were collected. Whole genome sequencing was used to analyze the pathogenic genes of the child, and Sanger sequencing was used to verify the suspected mutation sites of the family members. The clinical phenotype and genetic variation characteristics were analyzed, and the clinical characteristics of BVSYS were summarized in combination with relevant literature.Results:The patient, a female aged 3 years and 1 month, presented with global developmental delay, speech disorder, distinctive facial features, esotropia, epilepsy, hypotonia and atrial septal defect. Brain magnetic resonance imaging revealed bilateral ventriculomegaly with abnormal signal intensity in the posterior bodies of both lateral ventricles and thinning of the corpus callosum. The whole genome sequencing revealed a homozygous missense mutation c.518 (exon5) T>C (p.IIe173Thr) in the MED25 gene of the child, and Sanger sequencing confirmed that her parents and elder brother carried the aforementioned heterozygous mutation, which was classified as a likely pathogenic mutation according to the guidelines of the American College of Medical Genetics and Genomics. A total of 22 cases from 6 literature sources were retrieved, with no reported cases in China so far. Conclusions:BVSYS is clinically rare. For patients presenting with unexplained global developmental delay or intellectual disability combined with craniofacial, neurological, cardiac, and eye abnormalities, targeted genetic testing can facilitate a definite diagnosis.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Aim To express and purify recombinant hCGH-CTP fusion protein in high-density suspension culture of Chinese hamster ovary cells (CHO-S), and to verify the lipid accumulation effect of rhCGH-CTP on 3T3-L1 mature adipocytes. Methods The recombinant protein expression vector (pcDNA3. 1-rhCGH-CTP) was constructed, achieved by fusing the human glycoprotein hormone beta 5/alpha 2 cDNA with CTP Linker. The expression plasmid was transiently transfected into the suspended CHO-S to express rhCGH-CTP protein and then purified, and the protein biological activity was verified. Intervention with 3T3-L1 mature adipocyte cells for 24 h was performed to detect the changes of intracellular triglyceride (TG) level. Results Western blot results showed that rhCGH-CTP protein was successfully expressed in CHO-S cells, and the yield was up to 715. 4 mg • L~ . The secreted protein was purified by AKTA pure system with higher purity that was up to 90% as identified by SDS-PAGE. In addition, the intracellular cAMP content of mature adipocytes with high expression of TSHR gene significantly increased after intervention with different concentrations of rhCGH-CTP protein by ELISA kit, indicating that rhCGH-CTP protein had biological activity. Oil red 0 staining showed that compared with the control group, the lipid content of mature adipocytes in the intervention groups with different concentrations of rhCGH-CTP protein significantly decreased (P < 0. 05) . Conclusions The rhCGH-CTP protein has been successfully expressed and purified with biological activity, and effectively reduce TG. This research provides an important theoretical basis for further revealing the physiological role of CGH protein and its potential application in clinical practice.
