Five cases of carcinoma located in the middle portion of the esophagus were resected with end-to-end anastomosis in the left neck. The lower portion (about 2.5-4.0cm in length) of the esophaguswas reserved to preserve the physiological function of the lower esophageal sphincter. The operationwas satisfactory, especially in the prevention of regurgitant esophagitis. No tension was observed at the site "of the anastomosis, and blood supply to the esophagus was not disturbed. Adequate mobilization of the lesser curvature of the stomach was the most important step. Such complications as leakage of the esophageal anastomosis and stricture were not seen in these five cases. Regurgitation was not observed in short-term follow-up. A normal esophageal peristalsis and cardiac opening were observed by barium meal radiography after the operation.

Objective To evaluate the efficacy of long-pulsed tunable Nd: YAG laser on capillary hemangioma and to analyse its influencial factors. Methods A retrospective review was conducted on 124 patients with 135 vascular lesions treated with long-pulsed tunable Nd:YAG laser from February, 2007 to January, 2008. Working parameters, including spot size (3-5 mm), pulse duration (10-30 ms) and fluence (120-200 J/cm2) were determined based on the size, color and depth of lesions and adjusted according to the immediate reaction of lesions. The interval of two treatments was 1 month. Results Of the 135 lesions, 100 experienced a more than 95% subsidence, 22 achieved 60%-94% subsidence, 11 got 30% -59% subsidence, and 2 reached less than 30% subsidence. The cure rate and effective rate were 74.07% and 90.37% respectively. Smaller lesions showed a better response to the treatment than larger ones (P<0.0001), whereas the sites and depth of lesions had no effect on the efficacy (both P>0.05). Atrophy scar occurred in 4 (2.96%) lesions, and blisters in 12 (8.89%) lesions after the treatment. No purpura or pigmentary changes occurred. Conclusion The long-pulsed tunable Nd:YAG laser is an effective treatmnt for capillary hemangioma with fast action and few side reactions.

Objective:To understand the contents of edible salt iodine and urinary iodine of children and pregnant women in Yunnan Province, and to evaluate the iodine nutrition status, so as to provide a basis for scientific prevention and treatment of iodine deficiency disorders (IDD).Methods:From November to December 2020, one county (city) was selected from each prefecture (city), two townships (towns and streets) were selected from each county (city) and two villages (neighborhood committees) were selected from each township (town and street) from each of the 16 prefectures (cities) in Yunnan Province as the investigation sites. A total of 20 non-boarding children (male and female balanced) aged 8 - 10 years old were selected from each primary school in each village (neighborhood committee) to collect salt and urine samples. A total of 80 children were investigated in each county (city). A total of 20 pregnant women were selected from each township (town and street) to collect salt and urine samples. A total of 40 pregnant women were investigated in each county (city). All salt samples and urine samples were tested for iodine contents.Results:A total of 2 009 salt samples and 2 041 urine samples (1 375 for children, 666 for pregnant women) were collected from children aged 8 - 10 years old and pregnant women in 16 counties (cities) of Yunnan Province. Among them, the median salt iodine was 26.0 mg/kg, the coverage rate of iodized salt was 100.0% (2 009/2 009), the qualified rate of iodized salt was 98.7% (1 982/2 009), and the consumption rate of qualified iodized salt was 98.7% (1 982/2 009). The difference of salt iodine content in key populations in different counties (cities) was statistically significant ( H = 258.98, P < 0.01). The median urinary iodine of children aged 8 - 10 years old was 188.5 μg/L. There was statistically significant difference in urinary iodine content among children of different ages ( H = 29.45, P < 0.01), but there was no statistically significant difference in urinary iodine content among children of different genders ( H = 1.43, P > 0.05). In addition, the median urinary iodine of pregnant women was 141.9 μg/L, 52.1% (347/666) was < 150 μg/L. There was statistically significant difference in urinary iodine content of pregnant women in different counties (cities, H = 88.32, P < 0.01). Conclusions:The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in key populations of Yunnan Province are more than 90%, and the iodized salt supply is good. Iodine nutrition of children aged 8 - 10 years old is at an appropriate level (100 - 199 μg/L); iodine nutrition of pregnant women is in an state of iodine deficiency ( < 150 μg/L). It is suggested to strengthen IDD monitoring and health education among key populations, improve residents' awareness of disease prevention, and make scientific iodine supplementation.

Objective:This study sought to investigate the feasibility, anatomical indications and operating points of transcatheter aortic valve replacement (TAVR) procedure in the treatment of pure aortic regurgitation (AR).Methods:The medical records of 4 elderly patients with pure AR who were treated in the cardiology department, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 2020 to March 2021 were retrospectively analyzed. All patients were implanted with self-expandable valve stents via peripheral artery approach for TAVR treatment. The feasibility, anatomical indications and key points of TAVR were analyzed.Results:The 4 patients with pure AR who were carefully screened had an average age of 66 years, and all achieved TAVR treatment success without serious perioperative complications and death. Postoperative examination and follow-up data showed that cardiac functions and cardiac remodeling indexes were significantly improved.Conclusions:This exploratory study shows that TAVR is technically feasible and effective treatment option for selected elderly patients with native pure AR, which is worthy of further study.

BACKGROUNDFirst generation drug-eluting stents (DES) were associated with a high incidence of late stent thrombosis (ST), mainly due to delayed healing and re-endothelization by the durable polymer coating. This study sought to assess the safety and efficacy of the Nano polymer-free sirolimus-eluting stent (SES) in the treatment of patients with de novo coronary artery lesions.
METHODSThe Nano trial is the first randomized trial designed to compare the safety and efficacy of the Nano polymer-free SES and Partner durable-polymer SES (Lepu Medical Technology, Beijing, China) in the treatment of patients with de novo native coronary lesions. The primary endpoint was in-stent late lumen loss (LLL) at 9-month follow-up. The secondary endpoint was major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction or target lesion revascularization.
RESULTSA total of 291 patients (Nano group: n = 143, Partner group: n = 148) were enrolled in this trial from 19 Chinese centers. The Nano polymer-free SES was non-inferior to the Partner durable-polymer DES at the primary endpoint of 9 months (P < 0.001). The 9-month in-segment LLL of the polymer-free Nano SES was comparable to the Partner SES (0.34 ± 0.42) mm vs. (0.30 ± 0.48) mm, P = 0.21). The incidence of MACE in the Nano group were 7.6% compared to the Partner group of 5.9% (P = 0.75) at 2 years follow-up. The frequency of cardiac death and stent thrombosis was low for both Nano and Partner SES (0.8% vs. 0.7%, 0.8% vs. 1.5%, both P = 1.00).
CONCLUSIONSIn this multicenter randomized Nano trial, the Nano polymer-free SES showed similar safety and efficacy compared with the Partner SES in the treatment of patients with de novo coronary artery lesions. Trials in patients with complex lesions and longer term follow-up are necessary to confirm the clinical performance of this novel Nano polymer-free SES.
