Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

Objective To observe the safety and efficacy of levosimendan in the perioperative pe-riod for patients with pulmonary hypertension associated with valvular heart disease undergoing heart valve replacement surgery.Methods A total of 90 patients with pulmonary hypertension associated with valvular heart disease who underwent valve replacement surgery from April 2023 to May 2024 were enrolled.Based on the use of levosimendan,patients were divided into low-dose group,high-dose group,and control group,with 30 patients in each group.The control group received conventional drug therapy;the low-dose group received one dose of levosimendan from 3 days before surgery to 3 days after surgery combined with conventional drug therapy;the high-dose group received two doses of levosimendan from 3 days before surgery to 3 days after surgery combined with conventional drug therapy.Data on brain natriuretic peptide(BNP),left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),creatinine(Cr),mean pulmonary artery pressure(mPAP),PH related to left heart disease(PH-LHD)status,postoperative ICU stay,postoperative hospital stay,and cardiac function classification were collected and recorded at admission and before discharge.Results There were no statistically significant differences in gender,age,and body mass among the control group,low-dose group,and high-dose group(P＞0.05).There was no sta-tistically significant difference in the increase in Cr among the three groups(P＞0.05).There were statistically significant differences in postoperative ICU stay between the control group and the high-dose group,and between the control group and the low-dose group(P=0.017,0.028).However,there was no statistically significant difference in postoperative ICU stay between the low-dose group and the high-dose group(P=0.839).There were statistically significant differences in postopera-tive hospital stay between the control group and the high-dose group,and between the control group and the low-dose group(P=0.001,0.009),but no statistically significant difference was found between the low-dose group and the high-dose group(P=0.463).No serious complications oc-curred in any of three groups,and no patients withdrew from the study.Only one patient in the high-dose group experienced hypotension during the postoperative use of levosimendan,which nor-malized after fluid replacement.There was no statistically significant difference in the decrease in mPAP among the three groups(P＞0.05).There was a statistically significant difference in the de-crease in BNP between the control group and the high-dose group(P=0.025);however,there were no statistically significant differences in the decrease in BNP between the control group and the low-dose group,or between the low-dose group and the high-dose group(P=0.068,0.970).There was a statistically significant difference in the increase in LVEF between the control group and the high-dose group(P=0.019);however,there were no statistically significant differences in the increase in LVEF between the control group and the low-dose group,or between the low-dose group and the high-dose group(P=0.055,0.652).There were statistically significant differences in the decrease in LVEDD between the control group and the low-dose group,and between the control group and the high-dose group(P=0.019,0.033);however,there was no statistically significant difference between the low-dose group and the high-dose group(P=0.829).In the control group,18 patients(60.0％)had clinically effective treatment,22 patients(73.3％)in the low-dose group,and 24 patients(80.0％)in the high-dose group.There was no statistically significant differ-ence in clinical efficacy among the three groups(P=0.220).Conclusion Levosimendan is safe and effective in the perioperative period for patients with pulmonary hypertension associated with valvular heart disease,and high-dose use can more significantly improve LVEF and reduce BNP levels.

Objective:This article aimed to systematically evaluate the safety, feasibility and short-term outcomes of laparoscopic versus open radical resection for hilar cholangiocarcinoma.Methods:Relevant medical literatures published before November 30, 2021 were searched using PubMed, EMbase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP, CBM databases. Based on predetermined inclusion and exclusion criteria, articles were selected, and RevMan5.4 software was used to conduct the meta-analysis of this study.Results:Twelve comparative cohort articles were enrolled, which included 634 patients. There were 275 patients who underwent laparoscopic radical resection for hilar cholangiocarcinoma in the laparoscopic group, and 359 patients who underwent open radical resection for hilar cholangiocarcinoma in the open group. Meta-analysis showed that when compared with the open group, operation time of the laparoscopic group was significantly longer ( MD=58.36, 95% CI:13.54-103.18). However, intraoperative blood loss ( MD=-79.70, 95% CI:-90.01--69.39), hospital stay ( MD=-3.37, 95% CI:-4.29--2.45) and incision-related complications ( OR=0.36, 95% CI:0.16-0.80) were all significantly less (all P<0.05). The number of lymph node harvested, R 0 resection rates, postoperative bile leakage, intraperitoneal infection and effusion, total complication rates, and perioperative mortality and 1-year survival rates after operation between the two groups were not significantly different (all P>0.05). Conclusion:Laparoscopic radical resection for hilar cholangiocarcinoma was feasible and safe in selected patients carried out in an experienced hepatobiliary surgery center.

Objective To study the changes of resting-state brain activity in knee osteoarthritis(KOA)patients with chronic pain.Methods The data of 21 KOA patients (KOA group) and 21 healthy controls (HC group) who underwent standard resting-state fMRI scan were analyzed with regional homogeneity (ReHo) method to observe the changes in the patients in contrast to the controls.Results Compared to HC group,patients of the KOA group showed ReHo changes in bilateral frontal lobe,bilateral parietal lobe,bilateral temporal lobe,bilateral cerebellum,limbic system and default-mode network.Conclusion Patients with chronic pain demonstrate abnormal neuron activities in the brain regions, and control loops not only related with pain but also related with emotive function disorder and cognitive impairment.
