Objective To investigate the effectiveness and perioperative safety of ThermoCool SmartTouch SurroundFlow (STSF) catheter high-power ablation mode in the treatment of elderly patients with paroxysmal atrial fibrillation. Methods A total of 68 elderly patients with paroxysmal atrial fibrillation who used STSF catheter high-power ablation mode (STSF group) in Guangzhou First People's Hospital from January 2019 to June 2021 were analyzed retrospectively. There were 71 elderly patients with atrial fibrillation who had no significant difference in age, sex, left atrial diameter and left ventricular ejection fraction, used ThermoCool SmartTouch (ST) catheters for conventional power ablation (ST group) at the same time. The success rate of immediate circumferential pulmonary vein isolation, single lap isolation, operation time, X-ray fluoroscopy time, ablation time, intraoperative saline perfusion volume and the incidence of complications were compared between the two groups. Results Both groups of patients successfully completed circular pulmonary vein electrical isolation. There was no significant difference in the success rate of single-circle isolation between STSF group and ST group (left pulmonary vein 92.6% vs 90.1%, P>0.05; right pulmonary vein 83.8% vs 87.3%, P>0.05). Compared with ST group, STSF group had shorter operation and ablation time [(70.9±10.0) min vs (79.1±14.2) min, P<0.001; (25.4±4.5) min vs (30.5±6.3) min, P<0.001], lower perfusion volume [(406.5±46.3)mL vs (729.2±106.1)mL, P<0.001], similar X-ray fluoroscopy time [(6.5±2.5)min vs (7.3±2.6)min, P=0.056 ]. The perioperative complication rate of the two groups was low (2.9% vs 3.9%, P=0.39). Two cases of STSF group had steam pops during operation but did not cause pericardial tamponade, and 2 cases of ST group had postoperative heart failure occurred and improved after diuresis. One case developed persistent chest pain, which gastroscope indicated esophageal erosion, and recovered after liquid diet and PPI treatment. Conclusions Using STSF catheter high-power ablation mode to perform pulmonary vein isolation in elderly patients with paroxysmal atrial fibrillation could improve ablation efficiency, reduce intraoperative fluid load, and without increasing perioperative risk.

心率变异性与老年患者术后谵妄

Heart rate variability and postoperative delirium in elderly patients

:1-4
 
术后谵妄(POD)指术后严重的注意力及神经认知障碍,其发病率高,且可致多种术后并发症的发生率增加,老年患者为其高危人群之一。相关研究显示:心率变异性(HRV)作为反映自主神经系统(ANS)功能的生物电指标,与老年患者POD的发生相关。本文综述了近年HRV指数与老年患者POD关系的研究,描述了老年患者POD的流行病学规律、ANS功能异常引发POD的可能机制以及HRV与神经认知功能及POD的可能联系,以期为POD的防治提供新的思路。
Postoperative delirium (POD) is a syndrome of severe postoperative attention and neurocognitive impairment, which has a high incidence and can lead to an increased incidence of various postoperative complications. Elderly patients are one of the high-risk groups for POD. Relevant studies have shown that heart rate variability (HRV), as a bioelectrical indicator reflecting the function of the autonomic nervous system (ANS), is associated with the occurrence of POD in elderly patients. This paper reviewed the recent studies on the relationship between HRV index and POD in elderly patients, described the epidemiological regularity of POD in elderly patients, the possible mechanism of POD caused by abnormal ANS function, and the possible connection between HRV and neurocognitive function or POD, in order to provide new evidence for the prevention and treatment of POD.

Objectives To investigate the influence of thyroid function and related factors on blood lipid levels in patients with papillary thyroid cancer under short-term severe hypothyroidism. Methods Sixty-one patients with papillary thyroid carcinoma diagnosed by pathology were included. The data of thyroid function and blood lipid levels of all patients before operation and iodine treatment were collected. The effects of gender, age, operation mode, lymph node metastasis and other related factors on blood lipid were compared. Results Before iodine treatment, all blood lipid indexes were higher than the baseline level before operation. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (APO-A1), apolipoprotein B (APO-B), lipoproteins (LP) in the thyroid stimulating hormone (TSH)>60 mIU/L group were significantly higher than those in the TSH≤60 mIU/L group.Triglyceride (TG) and arteriosclerosis index (AI) levels were significantly lower in female patients compared with male patients, HDL-C and APO-A1 levels were lower in male patients compared with female patients, and TC levels were higher in patients aged>45 compared with those aged≤45, with significant differences (all P<0.05). No significant differences were observed in lipid levels among the different surgical procedures and lymph node metastasis subgroups (P>0.05). TC levels were negatively correlated with free triiodothyronines (FT3), free thyroxine (FT4), thyroxine (T4) levels (r=-0.342,-0.370,-0.340,respectively). HDL-C, LDL-C, and APO-B levels were negatively correlated with T4 levels (r=-0.294, -0.354, -0.324,respectively), APO-A1 levels were negatively correlated with FT4, triiodothyronine (T3), T4 levels (r=-0.306,-0.262,-0.263,respectively), and LP levels were negatively correlated with T3 and T4 levels (r=-0.268,-0.313, respectively). Conclusions Short term hypothyroidism before iodine treatment for papillary thyroid cancer could lead to the increase of full set of blood lipid indexes, male patients and middle-aged and elderly patients could also be accompanied by higher blood lipid levels.

Objective To investigate the effects of different concentrations of sinomenine on proliferation, cell cycle and apoptosis of renal carcinoma cells. Methods The renal carcinoma cells were treated with different concentrations of sinomenine. MTS was used to analyze the effects of sinomenine on proliferation in 786-O renal carcinoma cells, the cell cycle changes were determined using flow cytometry, while the changes of apoptosis were detected by Annexin V-FITC / PI double staining. The expression of apoptosis-related proteins such as c-myc, Bax and Caspase-3 were detected by Western blot. Results Sinomenine significantly inhibited the proliferation of 786-O cells and induced cell cycle arrest and apoptosis in G1/S phase. With the increase of sinomenine concentration, the inhibition rate increased gradually. Sinomenine significantly down-regulated the expression of c-myc protein, while the expressions of the apoptotic protein Bax, Caspase-3 were up-regulated. Conclusions Sinomenine can significantly inhibit the expression of c-myc in 786-O cells, reduce proliferation ability, and induce cell cycle arrest and apoptosis. Sinomenine may have a potential therapeutic effect on renal cancer.
