In this article,2017 Fleischner society lung nodules guidelines for management of lung nodules accidentally discovered and lung nodule measurement were briefly introduced.Electronic questionnaires were sent to doctors nationwide,and their familiarity and consistency with these recommendations were assessed.The results showed relatively high familiarity with the guideline,but the consistency in clinical practice was still unsatisfactory,suggesting that further promotion of these guidelines is necessary in the future.

Objective To investigate the effect of catheter-based peripheral sympathetic denervation (CPSD) on peripheral artery sympathetic tone of New Zealand rabbits.Methods Twenty New Zealand rabbits were randomly divided into CPSD group and control group (each n =10).Endovascular radiofrequency ablation above the bifurcation of the abdominal aorta was performed on the rabbits in CPSD group.Norepinephrine was infused with continuous trans-arterial pumping in both two groups.And laser Doppler flowmetry was used to measure the peripheral microperfusion and temperature of right hindlimb of rabbits.The changes of the peripheral microperfusion and temperature before (resting state) and after norepinephrine infused (norepinephrine load state) were compared between the two groups.Results Eight rabbits completed the procedure in each group.The change of peripheral microperfusion between resting and norepinephrine load states in CSPD group was lower than that in control group ([-37.19±22.56]％ vs [-57.02％±10.12]％,P=0.04),whereas the change of temperature was not significantly different between the two groups ([0.35±0.50]℃ vs [-0.21± 1.83]℃,P=0.43),while significant difference was noticed when two rabbits with abnormal temperature change in control group were neglected ([0.34± 0.50] ℃ vs [-1.14 ±0.72] ℃,P＜0.01).Conclusion CPSD can be used to decrease the peripheral artery sympathetic tone of New Zealand rabbits,and may play an important role in relieving symptoms of critical limb ischemia.

Objective:To analyze the operational efficiency and its changes of traditional Chinese medicine(TCM)hospitals in Guangdong province,and to provide empirical evidence for improving the operational efficiency of TCM hospitals in Guangdong Province.Methods:The three-stage DEA model was used to conduct a static analysis of the operating efficiency of TCM hospitals in Guangdong Province in 2022,and the Malmquist index was used to conduct a dynamic analysis of the changes in the operating efficiency of TCM hospitals in Guangdong Province from 2018 to 2022.Results:After eliminating the influences of environmental variables and random interference,the average values of comprehensive efficiency,pure technical efficiency and average scale efficiency of the TCM hospitals in Guangdong Province in 2022 were 0.970,0.982 and 0.988,respectively.From 2018 to 2022,the total factor productivity index of Guangdong's TCM Hospitals was 1.008.Conclusion:The overall operation efficiency of TCM hospitals in Guangdong is high,but there are obvious regional differences.Further improvement of operation efficiency is mainly restricted by pure technical efficiency.Operational efficiency needs to be further improved through measures such as coordinating the layout of resources in various places,improving the external environment,sounding the internal management system of hospitals,and fine-tuning operational management.

Objective To observe the effectiveness and safety of different methods under multi-disciplinary treatment(MDT)model for treating pulmonary arteriovenous malformation(PAVM).Methods MDT were retrospectively performed in 31 patients with PAVM.The effectiveness and safety of interventional therapy,surgical treatment and conservative therapy for PAVM were compared.Results Among 31 cases of PAVM,22 cases underwent interventional therapies(interventional group),4 cases received surgical treatments(surgical group)and 5 cases underwent conservative therapies(conservative group).In interventional group,PAVM was successfully embolized in all 22 cases,with the technical success rate was 100％(22/22).Pleurisy was occurred in 3 cases(3/22,13.64％),while recurrence of PAVM was noticed in 4 cases(4/22,18.18％)during follow-up.No recurrence occurred in interventional group after the second interventional therapies.In surgical group,4 cases were successfully treated with thoracoscopic lobectomy,with the technical success rate of 100％(4/4).No postoperative complication occurred,while recurrence of PAVM was noticed in 2 cases(2/4,50.00％)during follow-up,including 1 case underwent interventional therapy and 1 case underwent conservative therapy.In conservative group,progressive PAVM was observed in 3 cases(3/5,60.00％),including 2 cases who were cured with interventional therapy and 1 case died of stroke after conservative therapy.Conclusion Individualized treatments of PAVM were feasible under MDT model.Compared with surgical treatments and conservative therapies,interventional therapies of PAVM were more effective and relatively safe.
