Atrial fibrillation is the most common type of chronic cardiac arrhythmia. Catheter ablation and left atrial appendage occlusion are effective treatment methods for atrial fibrillation， but these procedures require anesthesia support. However， anesthetic drugs often cause side effects such as nausea， vomiting， involuntary movements， and respiratory depression. This paper presents a case of a successful one-stop procedure for cryoballoon ablation and left atrial appendage occlusion of atrial fibrillation performed entirely under acupuncture anesthesia. Thirty minutes before the procedure， acupuncture needles were inserted perpendicularly at bilateral Neiguan （PC 6）， Lieque （LU 7）， Ximen （PC 4） and （LU 6）. After obtaining the deqi （得气） sensation， an electroacupuncture device was connected， and electroacupuncture anesthesia was used for pain control throughout the procedure. The patient exhibited good tolerance and cooperation， with electroacupuncture anesthesia completely replacing intravenous anesthetics， ensuring the smooth completion of the surgery. Postoperative follow-up showed favorable outcomes.

Objective:To investigate the impact of early blood glucose fluctuations after acute multiple injuries on post-traumatic stress disorder (PTSD).Methods:This study was a case-control study. From March 2022 to March 2023, patients with acute multiple injuries who were admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University were selected. According to whether complicated with traumatic brain injury (TBI), the patients were divided into TBI group and non-TBI group. Early post-traumatic blood glucose fluctuations were observed, including stress-induced hyperglycemia (SIH), initial blood glucose value on admission, blood glucose extreme, short-term glycemic variability (GV) and other related indicators. The 72-hour glucose coefficient of variation (Glu-CV) was used to reflect short-term GV. After 1 month, the PTSD checklist for DSM-5 (PCL-5) was used to assess the patient's symptoms of PTSD. The patients were divided into PTSD group and non-PTSD group according to PCL-5 score ≥38. The differences in short-term glucose fluctuations in each groups were compared; the risk factors of PTSD were analyzed by logistic regression; the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of related indicators on the incidence of PTSD.Results:159 patients with acute multiple injuries were selected and defined as the TBI group ( n=94) and non-TBI group ( n=65). The incidence of PTSD, PCL-5 scale scores, the incidence of SIH and 72 h Glu-CV in the TBI group were significantly higher than the non-TBI group (all P<0.05). The incidence of SIH and 72 h Glu-CV in the PTSD group were significantly higher than the non-PTSD group (both P<0.05). Multivariate logistic regression analysis showed that 72 h Glu-CV ( OR=1.333, 95% CI: 1.028-1.727, P=0.030) was the independent risk factor for PTSD after acute multiple injuries, and the area under the ROC curve was 0.861 (95% CI: 0.789-0.933, P<0.001), the sensitivity was 62.9% and the specificity was 93.5%. Conclusion:Patients with acute multiple injuries with TBI are more likely to have early glucose fluctuations and develop PTSD, and increased short-term glucose variability is the independent risk factor for PTSD after acute multiple injuries.

Objective:To investigate the pollution levels and influencing factors of polybrominated diphenyl ethers (PBDEs) in household dust in five cities in northern China.Methods:Based on the "Chinese Indoor Environment and Health Surveillance" project carried out by the National Institute of Environmental Health, Chinese Center for Disease Control and Prevention in 2018-2019, during the warm season (April 2018 to September 2018) and the cold season (November 2018 to March 2019), Lanzhou in Northwest China, Shijiazhuang in North China, Panjin in Northeast China, Luoyang in Central China, and Qingdao in East China were selected as the research sites. A total of 87 families were recruited to study residences in real-life scenarios. At the same time, dust samples were collected to detect the concentration of PBDEs. The level of household environmental indicators was measured, and the residential building characteristics and family behavior habits were collected through questionnaires. A total of 142 valid dust samples and 140 valid questionnaires were obtained. The differences in PBDE concentrations across seasons, wind zones, residential building characteristics, and family habits were analyzed. The exploratory factor analysis was performed to investigate the possible sources of PBDEs, and multivariate linear regression was used to explore the factors influencing PBDEs in household dust.Results:The M ( Q1,Q3) of total PBDE concentrations in 142 household dust samples in five cities was 144.51 (106.61, 222.65) ng/g in the warm season and 145.10 (98.57, 180.65) ng/g in the cold season, respectively. There were seasonal differences in the concentration of ∑ 12PBDEs in Luoyang and Shijiazhuang ( P<0.01). The concentration of BDE-71 was highest among PBDE homologues, followed by BDE-66 and BDE-47. Three factors were extracted by exploratory factor analysis in the warm season, and the cumulative variance contribution rate was 67.90%. The multivariate linear regression showed that the house completion less than ten years [ β (95% CI): 0.186 (0.013, 0.359)], infrequent home cooking [ β (95% CI):-0.342 (-0.570, -0.114)], and increased residential PM 10 concentration [ β (95% CI): 0.001 (0.000, 0.002)] during the warm season, as well as the house far from driveway [ β (95% CI): 0.093 (0.013, 0.172)], house area less than 90 m 2 [ β (95% CI):-0.138 (-0.264, -0.013)], and lower residential xylene concentration [ β (95% CI):-0.006 (-0.011, -0.001)] during the cold season might be related to the elevated concentrations of ∑ 12PBDEs in household dust. Conclusion:The pollution of PBDEs in household dust in five northern cities is at a medium to high level. Years of house completion, frequency of cooking at home, residential PM 10 concentration, distance from house to driveway, house area, and residential xylene concentration may influence household PBDE concentrations.

Objective:To explore the clinical utility of liquid chromatography tandem mass spectrometry forprimary aldosteronism screening.Methods:From January to October 2019, 413 inpatients diagnosed hypertension from Fuwai Hospital of Chinese Academy of Medical Sciences were enrolled, including 60 Primary aldosteronism(PA)patients and 353 primary hypertension patients. The plasma aldosterone concentration (PAC) and renin concentration (DRC) were measured after 2 h of standing. The 24 h urine samples were collected for measurement of aldosterone using LC-MS/MS. The performance of urine aldosterone and urine aldosterone/renin ratio (UADRR) in PA screening was evaluated by ROC, and compared with PAC/DRC ratio (ADRR). Meanwhile, the efficiency of urine aldosterone in elderly patients or patients with low blood potassium or 24 h urine sodium over 200 mmol was investigated.Results:Area under the curve (AUC)of urine aldosterone was 0.725 (95 %CI 0.679-0.767), and the best cut-off was 7.13 μg/24 h, which was lower than AUC of ADRR (0.958, 95 %CI 0.934-0.975). The AUC of UADRR was 0.947 (95 %CI 0.920-0.966), the best cut-off was 1.11 (μg/24 h)/(μIU/ml), the sensitivity and specificity were 91.7% and 89.0%, respectively. There is no significant differences found with ADRR. In patients with 24 h urine sodium over 200 mmol, AUC of aldosterone was 0.834 (95 %CI 0.730-0.910) and the best cut-off was 9.31 μg/24 h. The sensitivity and specificity were 90.9% and 68.7%, respectively. For the elderly patients over 60 years old, the AUC of urinary aldosterone was 0.860 (95 %CI 0.770-0.925), and the best cut-off was 6.91 μg/24 h. The sensitivity and specificity were 84.6% and 81.3%, respectively. When admission blood potassium was less than 3.50 mmol/L, AUC of urinary aldosterone was 0.822 (95 %CI 0.684-0.917), and the best cut-off was 10.63 μg/24 h. The sensitivity and specificity were 85.7% and 66.7%, respectively. Conclusion:The detection of aldosterone in urine by LC-MS/MS can provide clinical information for PA screening, and the screening performance is better in patients with 24-hour urine sodium over 200 mmol, elderly patients or patients with low blood potassium. If combined with renin, screening efficiency was the same as that in ADRR.

Objective To investigate the value of multi-modal neuroendoscopy combined with microscopy in the treatment of solid cystic brain tumors. Methods Fifty patients with cystic solid tumors admitted to Wuzhou Worker′s Hospital(the Seventh Affiliated Hospital of Guangxi Medical University) from February 2016 to February 2019 were enrolled. The patients were divided into two groups by random number table method. The patients in control group (25 cases) received microsurgery, and the patients in observation group (25 cases) received microsurgery combined with neuroendoscopy. All patients underwent CT or MRI. The differences in tumor resection rate between the two groups were observed and compared. The postoperative complications and Glasgow Outcome Scale (GOS) scores were compared between the two groups. All patients were followed up for 12 months after surgery. The tumor recurrence rate and mortality rate of the two groups were compared. Results The total resection rate of the tumor in observation group was 80.00%(20/25), and in control group was 48.00%(12/25), and there was significant difference (P<0.05). The postoperative GOS score of observation group was higher than that of control group: (4.52 ± 1.73) scores vs. (3.65 ± 1.15) scores, t=2.094, P=0.041. The incidence of postoperative complications, tumor recurrence rate and the mortality rate between two groups had no significant difference (P>0.05). Conclusions Multi-modal neuroendoscopy combined with microscopy can significantly improve the total resection rate of cystic brain tumors and improve the prognosis without increasing the risk of surgery.

Objective To study the impact on the use of branched vascular allografts in the prevention of left regional portal hypertension after pancreatic cancer operations.Methods This retrospective study included 25 patients who underwent pancreaticoduodenectomy for pancreatic head cancer which involved the portal vein,superior mesenteric vein and splenic venous confluence between January 2011 to December 2017 in the Beijing Chao Yang Hospital,Capital Medical University.These patients underwent "en bloc" resection of the spleno-mesenterio-portal (SMS) venous axis with replacement of a branched vascular allografts.They were studied to see whether gastroesophageal varices were found on gastroscopy and whether there were any changes in leukocyte,platelet and splenic volume before and after the operation to determine the incidence of left regional portal hypertension after operation.Results During the follow-up period,all the portal vein,superior mesenteric vein and splenic vein anastomoses were unobstructed and without any thrombosis.No new varices were found on gastroscopy.There were no significant differences in the white blood cell count,platelets count and splenic volume before and after the operations (all P＞0.05).The 25 patients had no left regional portal hypertension.Survival time and one year survival rate of the patients were (20.2±3.7) months and 44.0％.Conclusion Branched vascular allografts effectively prevented the occurrence of left regional portal hypertension after radical pancreaticoduodenectomy with resection of SMP.

Objective To investigate the effects of cholinergic signal on neural stem cell(NSC)differenti-ation in peri-infarction region after ischemic stroke. Methods Mice were randomly assigned into sham + vehicle group,middle cerebral artery occlusion(MCAO)+ vehicle group,MCAO + donepezil group and MCAO + atro-pine group(n = 25). MCAO was induced by thread-occlusion method. Modified neurological severity score (mNSS)was used to evaluate neurological function recovery,and the brain water content was measured by dry-wet weight method. NeuN/5-bromodeoxyuridine(BrdU),CNPase/BrdU,GFAP/BrdU double-labeled cells were tested by immunofluorescence. Results Brain water content of MCAO + vehicle group was significantly higher than that of sham operation group(P < 0.05). Donepezil-treated MCAO mice had lower neurologic deficit scores and brain water content than of MCAO + vehicle group(P < 0.05). On day 14 and day 28 after MCAO,the NeuN/BrdU, CNPase/BrdU and GFAP/BrdU immune-positive cells of MCAO + vehicle group were markedly increased as com-pared with that of sham+vehicle group(P<0.05).Compared with that of MCAO+vehicle group,the number of NeuN/BrdU-positive cells,CNPase/BrdU-positive cells and GFAP/BrdU-positive cells was higher in MCAO+done-pezil group,and the number of NeuN/BrdU-positive cells and CNPase/BrdU-positive cells of MCAO + atropine group was lower(P < 0.05). Conclusions Cholinergic signal could promote NSCs differentiation in peri-infarc-tion region,a lleviate cerebral edema,and improve the brain function restoration after stroke.

Objective To evaluate the clinical outcomes of double-port video-assisted thoracoscopic lobectomy. Methods We retrospectively analyzed the clinical data of 72 patients who underwent double-port video-assisted thoracoscopic lobectomy(DP group)from October 2014 to December 2015 in our hospital.A paired comparison was made with 72 patients who had the same lesion location and the nature(benign or malignant)and underwent three-port video-assisted thoracoscopic lobectomy(TP group)in the same period.The clinical outcomes included operation time, intraoperative blood loss,the number of lymph node, the chest tube time,postoperative hospital stay, incision pain VAS scores within three days and complications.Postoperative follow-ups were taken with telephone calls or out-patient reviews. Results No operative morality occurred in both groups.There were no statistical significances between the DP Group and the TP Group in intraoperative blood loss[(107.9 ±56.6)ml vs.(95.0 ± 46.8)ml,t=1.490,P=0.138],the number of lymph node(13.9 ±2.7 vs.14.5 ±2.6,t=1.358,P=0.177)and complication rate[11.1%(8/72)vs.9.7%(7/72),χ2=0.074,P=0.785].The DP group had significant longer operation time[(153.6 ± 22.6)min vs.(143.6 ±25.8)min, t=2.474, P=0.015], shorter chest tube time[(5.2 ±1.7)d vs.(6.4 ±1.1)d, t=5.029,P=0.000],shorter postoperative hospital stay[(6.1 ±1.6)d vs.7.6 ±1.2, t=6.364, P=0.000], and lower incision pain VAS scores within three days[(12.3 ±1.9)points vs.(14.4 ±1.8)points, t=6.808, P=0.000]as compared to the TP group.No short-term complication was noticed in both groups during a follow-up time ranged from 6 to 20 months. Conclusions Double-port video-assisted thoracoscopic lobectomy is safe and feasible.It is a preferred surgical mode for selected cases.

Objective To investigate the effect of donepezil on subventricular zone ( SVZ) neuro-genesis related neurotrophic factors after cerebral infarction. Methods Mice were randomly assigned into three groups: vehicle-treated sham group (Sham+vehicle,n=18),vehicle-treated middle cerebral artery oc-clusion (MCAO) group (MCAO + vehicle,n=30) and donepezil-treated MCAO group (MCAO+donepezil, n=30). Middle cerebral artery occlusion( MCAO) was induced by thread-occlusion method. Nissl staining was used to measure the infarct volume and the modified neurological severity score(mNSS) was used to as-sess neurologic function and brain water content was detected to assess brain edema degree. Proliferative cells and neuroblasts were labeled with 5-bromodeoxyuridine ( BrdU) and doublecortin ( DCX). The SVZ BrdU+/DCX+cells were detected by immunofluorescence. The expression of glial cell line-derived neurotro-phic factor (GDNF),brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) were detec-ted by Western blot. Results The infarct volume of MCAO + donepezil group ((13. 33±4. 55)%) was sig-nificantly lower than that of MCAO + vehicle group ((31. 33±3. 93)%,t=7. 34,P<0. 05). The neurologic deficits were significantly ameliorated after donepezil treatment,and the brain water content of MCAO + done-pezil group ((71. 82±10. 18)%)was significantly less than that of MCAO + vehicle group ((85. 93± 7. 54)%,F=13. 480,P<0. 05). All differences were statistically significant (P<0. 05). The area of BrdU+/DCX+cells within SVZ of MCAO + vehicle group ((6. 16±1. 79)%) was significantly larger than that of sham + vehicle group ((2. 25±1. 09)%),and was fewer than that of MCAO+donepezil group ((16. 19± 2. 16)%,F=102. 756,P<0. 05). MCAO significantly promoted the expression of GDNF,BDNF and NGF within SVZ compared with sham operation,and donepezil increased these protein levels(F=15. 114,27. 121, 27. 398,P<0. 05). Conclusion Donepezil regulates neurogenesis via increasesing the expression of GDNF, BDNF and NGF within SVZ after cerebral infarction.
