Objective To investigate the clinical efficacy of combined acupuncture and medicine plus ultrashort wave diathermy in treating post-stroke complicated urinary tract infection.Methods One hundred and twenty patients with post-stroke complicated urinary tract infection were randomly allocated to groups A, B and C, 40 cases each. Group A received acupuncture, ultrashort wave diathermy and treatment with anti-infective drugs; group B, ultrashort wave diathermy and treatment with anti-infective drugs; group C, treatment with anti-infective drugs alone. The clinical therapeutic effects and the recurrence rates were compared between the three groups.Results The total efficacy rate was 92.5% in group A, 90.0% in group B and 72.5% in group C. There was a statistically significant difference in the total efficacy rate between group A or B and group C (P<0.05). The recurrence rate was 8.1% in group A, 27.8% in group B and 31.0% in group C. There was a statistically significant difference in the recurrence rate between group A and group B or C (P<0.05).Conclusion Combined use of acupuncture and medicine plus ultrashort wave diathermy is an effective way to treat post-stroke complicated urinary tract infection.

Objective To observe the effects of immune acupuncture and moxibustion on the infection in hospital and the outcome of re-habilitation after stroke. Methods From January, 2014 to January, 2016, 100 patients following acute stroke were randomly divided into ob-servation group (n=50) and control group (n=50). The control group accepted routine medications, rehabilitation and acupuncture, while the observation group accepted acupuncture and moxibustion on Guanyuan (RN4), Qihai (RN6) and Zusanli (ST36) in addition. The nosocomi-al infection rate was recorded 90 days after treatment, and the T lymphocyte subsets, scores of Fugl-Meyer Assessment (FMA) and modified Barthel index (MBI) were measured before and after treatment. Results The nosocomial infection rate was 20% in the observation group, less than 42% in the control group (χ2=5.657, P<0.05). The contribution of CD3+ and CD4+ T lymphocytes, and the scores of FMA and MBI increased after treatment in both groups (t>2.463, P<0.05), and increased more in the observation group than in the control group (t>2.225, P<0.05). Conclusion Immune acupuncture and moxibustion therapy can reduce the incidence of nosocomial infection, and promote the func-tion of the immune system and outcome in patients after acute stroke.

To study the chemical constituents of Veratrum dahuricum (Turcz.) Loes. f., a new aurone glycoside named as (Z)-7, 4'-dimethoxy-6-hydroxyl-aurone-4-O-β-glucopyranoside was isolated from the 95% ethanol extracts of the rhizomes and roots of Veratrum dahuricum (Turcz.) Loes. f. by repeated column chromatography on silica gel and recrystallization. Its structure was established by extensive spectroscopic analyses, and its cytotoxicities against HepG-2, MCF7 and A549 cell lines were measured in vitro.

Objective To investigate the effect of interventional therapy for Budd Chiari Syndrome(BCS). Methods 355 patients with BCS were examined with phlebography of inferior vena cava(PIVC) and percutaneous transhepatic hepatovenography(PTHV).The interventional procedures were based on the pathological changes of inferior vena cava(IVC) and main hepatic veins(MHVs).The procedures included PTA and/or stent placement of IVC,percutaneous transhepatic recanalization and dilation (PTHRD)of MHVs ,and percutaneous transjugular or transinferior vena cava recanalization and dilation with stent placement of MHVs(PTJRD and PTIRD ), percutaneous transhepatic recanalization or transinferior vena cava recanalization and dilation with stent placement of associated hepatic veins(AHVs). Results The success rate and recurrence rate were 96.0%(240/250) and 10.0 %(24/240), respectively, in PTA; the success rate was 91.4%(32/35 ) in PTHRD of MHVs; 90.0%(18/20 ) in PTJRD and PTIRD of MHVs , 100.0%(10/10) in PTJRD and PTIRD of AHVs; 90.0 %( 9/10 ) in PTA and stent placement plus PTHRD of AHVs. Severe complications occurred in 10 cases (2.8%). Conclusions Interventional therapy is simple, safe and effective for patients with some types of Budd Chiari Syndrome.

Objective:Based on single-center clinical results of endovascular recanalization for symptomatic non-acute internal carotid artery occlusion (ICAO), a new patient classification method is proposed to distinguish the most suitable ICAO patient subgroups for endovascular recanalization.Methods:A total of 140 patients with symptomatic non-acute ICAO accepted endovascular recanalization in Department of Cerebrovascular Intervention, He'nan Provincial People's Hospital from January 2019 to December 2021 were selected. These patients were divided into low risk group ( n=57), medium risk group ( n=54) and high risk group ( n=29) according to the occlusion segments, occlusion times, plaque features, calcification at the occlusion site and occlusion segment angulation. The immediate postoperative recanalization rate, perioperative complications, perioperative death, and prognoses 90 d after endovascular recanalization (modified Rankin scale scores of 0-2 as good prognosis) were evaluated in the 3 groups. Results:The immediate postoperative recanalization rate was 82.9% (114/140), perioperative complication rate was 11.4% (16/140), and perioperative mortality was 0.7% (1/140). The success recanalization rate decreased gradually from the low risk group to the high risk group (100%, 85.2%, and 37.9%), while the perioperative complication rate was the opposite (0%, 11.1%, and 34.5%), with significant differences ( P<0.05). Ninety d after endovascular recanalization, 109 patients had good prognosis and 27 had poor prognosis; the good prognosis rate in low risk group, medium risk group and high risk group was 98.2%, 79.6% and 34.5%, respectively, with significant differences ( P<0.05). The vascular restenosis rate in low risk group, medium risk group and high risk group was 0%, 8.7% and 18.2%, and re-occlusion rate was 0%, 6.5% and 27.2%, respectively, 90 d after endovascular recanalization, with significant differences ( P<0.05). Conclusion:Endovascular recanalization is technically feasible for patients with symptomatic non-acute ICAO, especially those met the criterions of low and medium risk groups in our study.

Objective To explore the risk factors and countermeasures of the perfusionist-related near-miss event (NME) in cardiopulmonary bypass (CPB). Methods The clinical data of the patients who underwent cardiac surgery in the Department of Cardiovascular Surgery, Nanfang Hospital, Southern Medical University from March 2020 to July 2021 were retrospectively analyzed. According to whether NME occurred during the operation, the patients were divided into an NME group and a non-NME group. The clinical data of the two groups were compared, and the risk factors for NME were analyzed. Results A total of 702 patients were enrolled, including 424 males and 278 females with a median age of 56.0 years. There were 125 patients in the NME group and 577 patients in the non-NME group. The occurrence rate of NME was 17.81%. Univariate analysis showed that there were statistical differences between the two groups in the gender, body surface area, CPB time, European system for cardiac operative risk evaluation score, emergency surgery, type of surgery, night CPB initiation, modified ultrafiltration use, multi-device control, average operation time, et al. (all P<0.05). The above variables were dimensionality reduction processed by least absolute shrinkage and selection operator regression, and the λ of minimum mean square error of 10-fold cross validation was 0.014. The variables of the corresponding model were selected as follows: multi-device control, night CPB initiation, minimum hematocrit, modified ultrafiltration use, CPB time. The results of multivariate logistic regression showed that night CPB initiation [OR=9.658, 95%CI (4.735. 19.701), P<0.01] and CPB time [OR=1.003, 95%CI (1.001, 1.006), P=0.014] were independent risk factors for NME. Conclusion Night CPB initiation and CPB time are independent risk factors for NME during CPB, which should be recognized and early warned in clinical work.

Objective:To evaluate the safety and efficacy of endovascular interventional treatment of the intracranial vertebrobasilar trunk large aneurysms (VBTLAs) compared with conservative treatment.Methods:This is a prospective multi-center cohort study. From October 2012 to October 2018, a total of 69 patients with intracranial vertebrobasilar trunk large aneurysm (diameter>10 mm) from Henan Province People's Hospital and People's Liberation Army Rocket Medical Center were included in this study. Patients themselves chose either endovascular interventional therapy (interventional group) or conservative treatment (conservative group) after discussion with their doctors. The χ 2 test was used to compare the incidence of deaths, stroke, and all other serious adverse events including other site bleeding, myocardial infarction and others between the two groups. Results:A total of 69 patients were enrolled, of whom 51 patients were enrolled in interventional group, 18 patients underwent endovascular reconstructive therapy, 11 patients underwent deconstructive therapy, and 4 patients underwent conjunction interventional treatments. Eighteen patients were enrolled in conservative group, of whom 11 cases received simple risk factor control, 7 cases received antiplatelet and risk factors control. The proportions of hypertensive patients 94.4% (17/18) and giant aneurysms 50.0% (9/18) in the conservative group were higher than those in the surgery group 64.7% (33/51, χ 2=4.500, P=0.034), 19.6% (10/51, χ 2=4.730, P= 0.030).The incidence of all serious adverse events associated with protocol was 15.7% (8/51) in the interventional group and 44.4% (8/18) in the conservative group [risk ratio (RR) =0.353, 95% confidence intervals (CI): 0.156-0.801], and the difference was significant (χ 2=4.668, P=0.031). The incidence of fatal events associated with protocol was 2.0% (1/51) in the interventional group and 38.9% (7/18) in the conservative group (RR=0.050, 95%CI: 0.007-0.382), and the difference was significant (χ 2=14.281, P<0.001). The incidence of hemorrhage events associated with protocol was 2.0% (1/51) in the interventional group and 22.2% (4/18) in the conservative group (RR=0.088, 95%CI: 0.011-0.738), and the difference was significant (χ 2 =5.391, P=0.020). Follow-up imaging showed that the occlusion rate of aneurysms in 44 patients in the interventional group was 56.8% (25/44) after a median follow-up of 6 months. Imaging follow-up was obtained in 9 patients, whose occlusion rate of aneurysms was 0 and the median follow-up time was 12 months, in the conservative group. The difference was significant(χ 2 =7.534, P=0.006). Conclusion:Compared with conservative treatment, endovascular intervention of the intracranial VBTLAs has lower incidences of serious adverse events and death events.
