ABSTRACT
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.
ABSTRACT
Objective To compare the clinical curative effect and security between microwave ablation treatment and surgical resection of benign thyroid nodules.Methods The imaging and clinical data of 100 cases of patients with benign thyroid nodules were collected,44 cases with 53 nodules were treated by microwave ablation treatment (ablation group),and 56 cases with 60 nodules were treated by surgical resection (surgery group).The rates of nodule regression in 1,3,6,12months after treatment,the size and changes of benign thyroid nodules in patients treated with microwave ablation therapy,as well as postoperative adverse reactions,time of inhospital were observed.Results The rates of nodule regression in 1,3,6,12 months therapy group were 54.55 ％,72.73 ％,95.45 ％,95.45 ％,while the rates in surgeny group were 100 ％.In the 1,3 months after treatment,the rates of nodule regression in ablation group were lower than those in surgery group (both P＜0.001).In the 6,12 months after treatment,the rates had no statistically significant differences in both groups (both P=0.245).With the extension of observation time,the nodule volume of the patients treated with microwave ablation therapy had a tendency to continue to shrink,particularly in the first 6 months.The incidence of hypothyroidism in ablation group was lower than surgery group (P=0.019).The difference of the incidence s of hematoma,infection,voice hoarse,parathyroid injury were not statistically significant in both groups (all P＞0.05).The time of inhospital in ablation group was obviously shorter than that in surgery group (t=-8.499,P=0.001).Conclusion Microwave ablation treatment of benign thyroid nodules has guaranteed results.It has the following advantages such as less complications,small trauma,short hospitalization time.So it has a broad prospect in clinical application.
ABSTRACT
Objective To investigate radioactivity levels in the main agriculture products around a uranium mine in Northern Guangxi.Methods The agriculture products and soil samples were collected and analyzed by using HPGe gamma ray spectrometer.Results The specific activity of 226Ra in radish (including leaf),radish leaves and radish,collected in one place,were 45.0,66.7 and 32.3 Bq/kg,respectively.Those of 226Ra and 23SU in the radish soil collected in the same place were 19 672 and 85 917 Bq/kg,respectively.The transfer coefficients of soil-to-radish and soil-to-leaves were 1.61 × 10-3 and 3.40 × 10-3,consistent with those reported in relevant literature.Radioactivity levels in agricultural products in another survey was in consistence with those in the national survey for food products.Radioactivity levels in soil elsewhere near the radish site was consistent with the results of the national soil radioactivive background survey.Conclusions The soil in this place has been contaminated by the nearby uranium mine.It is important to investigate this place further and take the necessary measures.
