OBJECTIVE: To explore the clinical and genetic characteristics of a Chinese pedigree affected by glycogen storage disease (GSD) type Ia with gout as the first manifestation. METHODS: Clinical and biochemical data of the pedigree were collected. Available members of the pedigree were subjected to gene sequencing, and the result was analyzed by bioinformatics software. The pedigree was followed up for five years. RESULTS: The proband was a young female manifesting recurrent gout flare, hypoglycemia, and hypertriglyceridemia. One of her younger brothers also presented with dysplasia and hepatic adenoma. Gene sequencing revealed that the proband and her younger brother both harbored c.1022T>A (p.I1e341Asn) and c.230+5G>A compound heterozygous variants of the G6PC gene , which were inherited from their father and mother, respectively. Among these, the c.230+5G>A is an intron region variant which was unreported previously, and bioinformatics analysis showed that it may impact mRNA splicing of the gene. The proband was treated with raw corn starch, allopurinol, and fenofibrate. Gout was well controlled, and she had given birth to a baby girl without GSD. CONCLUSION GSD Ia should be considered among young gout patients with hypoglycemia and hepatomegaly, for which gene sequencing is warranted. GSD Ia has a good prognosis after comprehensive treatment with diet and medicine.

Objective:To improve the differential diagnosis of systemic sclerosis (SSc) with hypertension and renal insufficiency.Methods:The clinical characteristics, diagnosis and treatment of a SSc patient with hypertension and renal insufficiency were reported and discussed.Results:A middle-aged female patient with a history of SSc for 5 years, headache and gross hematuria for 10 days was admitted. Abrupt increase in blood pressure and creatinine, glomerular hematuria, proteinuria, low complement C3 and C4, positive antinuclear antibody (ANA), anti-dsDNA antibody and perinuclear antineutrophil cytoplasmic antibody (pANCA) were presented. Renal pathology showed lupus nephritis (LN) (type Ⅳ). After glucocorticoid pulse therapy, followed by cyclophosphamide, belimumab, and symptomatic treatment, the symptoms were relievedand lupus disease activity were decreased.Conclusion:For SSc patients with increased blood pressure and creatinine, the presence of other diseases should be considered in addition to scleroderma renal crisis. Renal biopsy and pathological examination should be performed to confirm the diagnosis and avoid misdiagnosis.

Objective:To develop an online interactive cytopathological training program, and to evaluate it for improving the cytopathological diagnostic ability of endoscopists in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreas.Methods:A total of 5 500 cytopathological images were collected from 194 patients with pancreatic solid mass who underwent EUS-FNA in Nanjing Drum Tower Hospital from August 2018 to August 2019. The cell type in each cytopathological picture was labeled by senior cellular pathologists, which was used to build a learning and testing platform for online interactive cytopathological training. Five endoscopists without cytopathological background were invited to participate in this training. Sensitivity, specificity, positive predictive value and negative predictive value of endoscopists in differential diagnosis of cancer and non-cancer before and after training were compared to evaluate the effect of the online interactive cytopathological training program on improving the ability of endoscopists in diagnosis of cytopathology.Results:A cytopathological training platform for endoscopists to learn and take online test was successfully built. Before training, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosis of cancer and non-cancer for endoscopists were 0.55 (95% CI: 0.53-0.58), 0.32 (95% CI: 0.30-0.35), 0.43 (95% CI: 0.41-0.45), 0.44 (95% CI: 0.41-0.47) and 0.43 (95% CI: 0.42-0.45), respectively. After training, the above indicators were 0.96 (95% CI: 0.95-0.97), 0.70 (95% CI: 0.68-0.73), 0.74 (95% CI: 0.72-0.76), 0.95 (95% CI: 0.94-0.96) and 0.81 (95% CI: 0.80-0.83), respectively, which were significantly improved compared with those before ( P<0.001). Conclusion:The online interactive cytopathological training program can improve the understanding and diagnostic ability of endoscopists in pancreatic cytopathology, help to implement rapid on-site evaluation in the process of EUS-FNA, and improve the diagnostic efficiency of EUS-FNA.

OBJECTIVE: To investigate the effect of the combination of atrial fibrillation (AF) ablation and left atrial appendage closure (LAAC) on cardiac function and the success rate of AF ablation. METHODS: We retrospectively analyzed the data of 56 patients with AF undergoing a one-stop procedure for AF ablation and LAAC in our hospital between May, 2015 and May, 2019. Propensity score matching (PSM) at the ratio of 1:1 was used to select 56 control patients undergoing AF ablation at high risk of stroke, for matching with the hybrid procedure group. The perioperative complications, thromboembolic events, recurrence of atrial arrhythmia and cardiac function were compared between the groups. RESULTS: The two groups of patients were comparable for age, gender, BMI, duration and type of AF, concomitant diseases, CHA2DS2-VASc and HAS-BLED scores ( CONCLUSIONS The combination of AF ablation and LAAC is safe but does not improve the success rate of AF ablation. The one-stop procedure can improve cardiac function of the patients, but AF ablation alone can achieve better improvement of cardiac function.
