RESUMO
In the context of global digitalization, the digitalization development of Traditional Chinese Medicine (TCM) is inevitable. The construction of digital China should comply with the development trend of the information age and the general situation of domestic and international development, be forward-looking, scientifically planned, and coordinated to promote. The "14th Five Year Plan" also clearly pointed out that "Internet plus TCM" should be elevated to the level of national development strategy, and the digitalization transformation of TCM will definitely become a consensus for the transformation and development of TCM disciplines in the new era and new period. Based on the materials, this paper analyzed the dilemmas faced by the modernization of TCM culture dissemination, and put forward corresponding countermeasures, with a view to contributing to the power of TCM to promote the construction of digital China.
RESUMO
Objective:To evaluate the safety and efficacy of endoscopic cryoablation (ECA) in patients with upper tract urothelial carcinoma (UTUC).Methods:The clinical data of 9 patients with UTUC treated with ECA from April 2018 to September 2019 were retrospectively analyzed. Patients consisted of 3 males and 6 females, with median age of 76 years old (ranging from 50 to 88 years old). Among the patients, 6 cases had tumors of ureter, 1 case had tumor of renal pelvis and 2 cases had tumors of renal pelvis combined with ureter. Of the 9 patients, two had bilateral UTUC, six were presented with single lesion, three were presented with multiple lesion. The size of tumors were (1.53±0.91)cm. The tumors of all cases were localized (≤stage T 2), and there was no carcinoma or suspicious lymph node/distant metastasis. All patients enrolled in this study had strong will to choose kidney-sparing therapy. Biopsy, resection of intraluminal lesion with laser and cryoablation under ureteroscopy or percutaneous nephroscopy was performed under general aneasthesia.Ureteroscopy was performed 3 months after cryoablation. Perioperative complications and follow-up results were recorded and assessed. Results:Cryoablation was successfully performed in patients under ureteroscopy (n=8) or nephroscopy (n=1). The median cryoablation time was 6 (ranging from 4-16) minutes. The median follow-up was 16 months (ranging from 4-24 months). No tumor recurrence was observed at primary sites during follow-up. Two patients with multiple lesions were observed denovo ureteral neoplasms outside the primary sites 3 months and 6 months after cryoablation and treated with second cryoablation. One case died due to cardiovascular events 4 months after surgery. One patient underwent ureteral stricture during follow-up and received ureteroscopic balloon dilatation. No recurrent stricture was found in this case during the subsequent follow-up of 16 months. The other 5 cases showed no recurrence or complications like stricture during follow-up.Conclusions:ECA could probably be a promising treatment for localized UTUC. No recurrence in primary site and low incidence of ureteral stricture was observed during follow-up. The efficacy and safety of ECA need to be verified with large sample study.
