This study aimed to examine the short-term effect of the no-touch technique on the patency rate of a great saphenous vein (GSV) bridge used during off-pump coronary artery bypass grafting (OPCABG).

Between June 2018 and September 2020, 140 patients undergoing OPCABG, with grafts obtained from the GSV using the "no-touch" technique or the left internal mammary artery (LIMA), were enrolled in this study. The early clinical results and short-term patency rate of the OPCABG were evaluated at a three-month follow-up by comparing the patency rate of the LIMA bridge and the GSV bridge obtained by the no-touch technique. This study also analyzed the impacts of the postoperative complications of the lower limbs and the distribution area of diseased vessels on the patency rate of a GSV bridge obtained by the no-touch technique at an early stage.

No perioperative death or adverse cardiovascular or cerebrovascular events occurred in the 140 patients undergoing OPCABG. The difference in the early patency rate between the GSV bridge obtained by the no-touch technique and the LIMA bridge was not statistically significant (95.9% vs 97.1%, p = 0.501). There was no significant difference in the patency rate between an end-to-side anastomosed venous bridge and a LIMA bridge (95.0% [248/261] vs 97.1% [136/140], p = 0.314). Sepantronium Survivin inhibitor The overall patency rate of a no-touch vein bridge in the right coronary artery region was lower than it was in the left coronary artery region (93.8% [165/176] vs 97.9% [183/187], p = 0.049).

The no-touch technique may improve the early patency rate of a GSV bridge, and its effect is similar to that of a LIMA bridge.

The aim of the study was to explore the nature of a V-shaped sign in the backbone of the fifth lumbar vertebra revealed by whole-body bone scintigraphy (WBBS).

A local single-photon emission computed tomography (SPECT) scan plus a computed tomography (CT) scan were performed on 41 patients in our department who had a V-shaped sign in the backbone of the fifth lumbar vertebra detected by WBBS. Image fusion was conducted to understand the manifestations of the changes in the V-shaped sign in the CT images in WBBS and to determine the nature of the lesion.

All 41 patients presented with degenerative changes observed in the bilateral posterior zygapophysial joint of the fifth lumbar vertebra in the CT imaging bone window, bone hyperplasia of the articular process, joint surface hardening, and a joint gap. The vacuum sign could also be seen in some of these patients.

The typical V-shaped sign in the posterior zygapophysial joint of the fifth lumbar vertebra revealed by WBBS suggests degenerative changes in the zygapophysial joint of the fifth lumbar vertebra.

The present study aimed to identify the risk factors for early postoperative recurrence of hepatocellular carcinoma (HCC) in patients with microvascular invasion (MVI) and develop a predictive model.

Patients who underwent surgery for HCC with pathological identification of MVI at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2014 to June 2019 were consecutively enrolled in this study. A total of 416 patients were included, divided into an early recurrence group (N = 169) and a non-early recurrence group (N = 247), taking 12 months as the cut-off point for early recurrence. Univariate and multivariate Cox analysis was adopted to screen for risk factors for recurrence, and independence of risk factors was determined by logistic regression analysis. All variables were included in the logistic regression analysis. As previous studies have shown that tumor diameter is a risk factor for recurrence, this was also included in the analyses. A predictive model for early recurrence wasactors for early postoperative recurrence. The predictive model developed by applying the above risk factors had good predictive value in patients with early postoperative recurrence.
Protamine is a polycationic, and a strong basic peptide isolated from Clupeidae or Salmonidae fishes' sperm, which is rich in arginine and highly alkaline.

To explore the effect of lidocaine pre-treatment on protamine-induced pulmonary vascular reaction during the repair of congenital heart disease.

Eighty patients undergoing repair of congenital heart disease were randomly divided into four groups A
(non-pulmonary hypertension + lidocaine pre-treatment) group, A
(non-pulmonary hypertension + normal saline) group, B
(pulmonary hypertension + lidocaine pre-treatment) group, and B
(pulmonary hypertension + normal saline) group. Hemodynamic parameters, pulmonary inflammation, and pulmonary function were assessed at six intraoperative time points, two intraoperative time points and three intraoperative time points, respectively.
-value <0.05 was considered statistically significant.

A
group exhibited increased PAP, Paw, RI and A-aDO
. B
group exhibited increased Paw, RI and A-aDO
and decreased Cydn and OI after protamine administration. These changes were not observed in A
and B
group. Compared with A
and B
groups, plasma TXB
level in A
and B
group was higher, but 6-keto-PGF
in A
and B
groups was lower. Incidence of protamine adverse reactions in A
and B
group was lower than that in A
and B
group.

Precondition of lidocaine before neutralization of heparin may be effective for protamine-induced pulmonary vascular reaction during CHD repair.

Complete revascularization (CR) of hemodynamically stable STEMI improves outcomes when compared to culprit-only PCI. However, the optimal timing for CR (CR during index PCI [iCR] versus staged PCI [sCR]) is unknown. sCR is defined as revascularization of non-culprit lesions not done during the index procedure (mean 31.5±24.6 days after STEMI). Our goal was to determine whether iCR was the superior strategy when compared to sCR.

A systematic review of Medline, Cochrane, and Embase was performed for RCTs reporting outcomes of stable STEMI patients who had undergone CR. Only RCTs with a clearly defined timing of CR, for the classification into iCR and sCR, and a follow-up of at least 12 months were included. Seven RCTs comprising 6647 patients (mean age62.9±1.4 years, male sex79.4%) met these criteria and were included.

After a mean follow-up of 25.1±9.4 months, iCR was associated with a significant reduction in cardiovascular mortality (risk ratio [RR] 0.48, 95% confidence interval [CI] 0.26-0.90, p=0.02, relative risk reduction [RRR] 52%) and non-fatal reinfarctions (RR 0.
