Objective:To explore the relationship between serum levels of transforming growth factor- β1 (TGF- β1), vascular endothelial growth factor (VEGF) and tumor markers and local recurrence after breast-conserving surgery in patients with breast cancer. Methods:104 patients with breast cancer who underwent breast-conserving surgery in Xi’ an Central Hospital from Jan. 2020 to Dec. 2022 were selected and followed up for 1 year after surgery. According to the occurrence of local recurrence, they were divided into recurrence group ( n=16) and non-recurrence group ( n=88). The levels of serum TGF- β1, VEGF and tumor markers [carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) ] were compared between the two groups of patients. Univariate and multivariate Logistic regression analyses were used to analyze the influencing factors of local recurrence after breast-conserving surgery. Receiver operating characteristic (ROC) curve was applied to analyze the predictive value of TGF- β1, VEGF, CA125 and CEA on local recurrence after breast-conserving surgery. Results:The levels of VEGF, TGF- β1, CAl25 and CEA in recurrence group [ (358.83±38.00) ng/L, (849.90±74.19) U/mL, (18.34±1.61) ng/L and (40.20±5.64) ng/mL] were higher than those of (296.05±39.57) ng/L (742.85±79.96) ng/L, (14.97±1.66) U/mL and (32.79±4.72) ng/mL in non-recurrence group (all P<0.05). Lymph node metastasis, postoperative adjuvant therapy, tumor diameter and TNM staging were independent risk factors of local recurrence after breast-conserving surgery (all P<0.05). The areas under the ROC curves (AUCs) of serum VEGF, TGF- β1, CAl25 and CEA in predicting local recurrence after breast-conserving surgery were 0.847, 0.834, 0.925 and 0.935 respectively. The AUC of CEA was the largest, with sensitivity of 85.23% and specificity of 100% (all P<0.05) . Conclusions:The levels of TGF- β1, VEGF, CAl25 and CEA in patients with local recurrence after breast-conserving surgery are increased, and their levels are more effective in predicting local recurrence after breast-conserving surgery. Local recurrence after breast-conserving surgery is also affected by lymph node metastasis, postoperative adjuvant therapy, tumor diameter and TNM staging.

Primary ciliary dyskinesia (PCD) is a highly heterogeneous recessive inherited disorder. FAP54, the homolog of CFAP54 in Chlamydomonas reinhardtii, was previously demonstrated as the C1d projection of the central microtubule apparatus of flagella. A Cfap54 knockout mouse model was then reported to have PCD-relevant phenotypes. Through whole-exome sequencing, compound heterozygous variants c.2649_2657delinC (p. E883Dfs*47) and c.7312_7313insCGCAGGCTGAATTCTTGG (p. T2438delinsTQAEFLA) in a new suspected PCD-relevant gene, CFAP54, were identified in an individual with PCD. Two missense variants, c.4112A>C (p. E1371A) and c.6559C>T (p. P2187S), in CFAP54 were detected in another unrelated patient. In this study, a minigene assay was conducted on the frameshift mutation showing a reduction in mRNA expression. In addition, a CFAP54 in-frame variant knock-in mouse model was established, which recapitulated the typical symptoms of PCD, including hydrocephalus, infertility, and mucus accumulation in nasal sinuses. Correspondingly, two missense variants were deleterious, with a dramatic reduction in mRNA abundance from bronchial tissue and sperm. The identification of PCD-causing variants of CFAP54 in two unrelated patients with PCD for the first time provides strong supportive evidence that CFAP54 is a new PCD-causing gene. This study further helps expand the disease-associated gene spectrum and improve genetic testing for PCD diagnosis in the future.

Objective: To study the effect of hyperbaric oxygen (HBO) treatment of severe brain injury.Methods: Fifty-five patients were divided into a treatment group (n = 35 receiving HBO therapy ) and a control group (n = 20 receiving dehydrating, cortical steroid and antibiotic therapy) to observe the alteration of clinic GCS (Glasgow Coma Scale), brain electric activity mapping (BEAM), prognosis and GOS (Glasgow Outcome Scale) before and after hyperbaric oxygen treatment.Results: In the treatment group GCS, BEAM and GOS were improved obviously after 3 courses of treatment,GCS increased from 5.1 to 14.6 ( P ＜ 0.01-0.001 ), the BEAM abnormal rate reduced from 94.3％ to 38％ (P ＜0.01-0.001 ), the GOS good-mild disability rate was 83.7％, and the middle-severe disability rate was 26.3％compared with the control group. There was a statistic significant difference between the two groups (P ＜ 0.01-0.001).Conclusions: Hyperbaric oxygen treatment could improve obviously GCS, BEAM and GOS of severe brain injury patients, and effectively reduce the mortality and morbidity. It is an effective method to treat severe brain injury.

Objective To evaluate the effect of percutaneous transhepatic embolization of gastroesophageal varices on acute upper gastrointestinal bleeding in cirrhotic portal hypertensive patients. Methods Percutaneous transhepatic embolization was performed in 37 cases of acute upper gastrointestinal bleeding until varix thrombosed. Results Bleeding stopped in all patients. No technical complications occurred. During 1～38 months follow-up, variceal bleeding recurred in two cases in 3 months. One died of heart failure, five died of hepatic carcinoma in 6 months . Conclusion Percutaneous transhepatic embolization of gastroesophageal varices is a safe and effective treatment for acute upper gastrointestinal bleeding in portal hypertensive patients.
