Objective:To explore the influencing factors of left ventricular thrombus (LVT) in patients with non-ischemic heart failure (NIHF) and to construct a nomogram prediction model for NIHF patients with LVT.Methods:This study was a case-control study. A total of 2 592 patients with NIHF hospitalized in Beijing Anzhen Hospital affiliated to Capital Medical University from January 2018 to July 2022 were selected. Fifty-one patients with LVT identified by echocardiography and cardiac magnetic resonance were classified into LVT group. One hundred and sixty patients were selected as the non-LVT group using a 1∶3 propensity score matching based on age and gender. Multivariate logistic regression analysis was used to explore the influencing factors of LVT in patients with NIHF. A nomogram prediction model was constructed, and the area under (AUC) the receiver operating characteristic (ROC) curve was calculated to evaluate the predictive effect of the model.Results:A total of 211 patients were enrolled, with a median age of 40 years old and 160 males (76%). Compared with non-LVT group, LVT group had lower systolic blood pressure ((112±20) mmHg vs. (120±19) mmHg; 1 mmHg=0.133 kPa), lower left ventricular ejection fraction (LVEF; (27±12)% vs. (39±14)% ), lower proportion of patients with history of hypertension (28% (14/51) vs. 44% (70/160)) and atrial fibrillation (8% (4/51)vs.39% (62/160)), higher proportion of patients with New York Heart Association functional class Ⅲ to Ⅳ (class Ⅲ: 59% (30/51) vs. 41% (66/160); class Ⅳ: 28% (14/51) vs. 19% (31/160)), and larger left ventricular end-systolic diameter (LVESD; (56±14) mm vs. (50±15) mm). The levels of hemoglobin ((152±23) g/L vs. (142±30) g/L), D-dimer (508 (300, 1 105) μg/L vs. 158 (68, 379) μg/L), and N-terminal pro-brain natriuretic peptide (3 429 (2 462, 4 734) ng/L vs. 1 288 (422, 2 544) ng/L) were higher in LVT group than in non-LVT group ( P all<0.05). LVT group had a higher proportion of patients using beta-blockers (92% (47/51) vs. 78% (124/160)), angiotensin-converting enzyme inhibitors or angiotensin receptor blockers or angiotensin receptor neprilysin inhibitors (88% (45/51) vs. 72% (115/160)), and anticoagulant drugs (98% (50/51) vs. 32% (51/160)) than non-LVT group (all P <0.05). Multivariate logistic regression showed that reduced LVEF ( OR=1.08, 95% CI 1.02-1.15, P=0.008), decreased LVESD ( OR=1.07, 95% CI 1.01-1.12, P=0.013), and increased D-dimer levels ( OR=5.40, 95% CI 1.98-14.74, P=0.001) were independent influencing factors for LVT in patients with NIHF. The ROC curve showed that the AUC of the nomogram for predicting LVT in patients with NIHF was 0.793 (95% CI 0.710-0.876, P<0.001). Conclusion:Reduced LVEF, decreased LVESD, and elevated D-dimer are associated with LVT in NIHF patients. The predictive model developed based on the above indicators has certain value in predicting LVT in NIHF patients.

Although great progress has been achieved in the techniques and materials of cardiopulmonary bypass (CPB), cardiac surgery under CPB is still one of the surgeries with the highest complication rate. The systemic inflammatory response is an important cause of complications, mainly characterized by activation of innate immune cells and platelets, and up-regulation of inflammatory cytokines. After activation, a variety of molecules on the membrane surface are up-regulated or down-regulated, which can amplify tissue inflammatory damage by releasing cytoplasmic protease and reactive oxygen species, and activate multiple inflammatory signaling pathways in the cell, ultimately leading to organ dysfunction. Therefore, the expression of these cell membrane activation markers is not only a marker of cell activation, but also plays an important role in the process of vital organ injury after surgery. Identification of these specific activation markers is of great significance to elucidate the mechanisms related to organ injury and to find new prevention and treatment methods. This article will review the relationship between these activated biomarkers in the innate immune cells and vital organ injuries under CPB.

Objective:To explore the application value and treatment effects of multiple free anterolateral perforator flaps of calf for reconstruction of multiple digital wounds in single hand.Methods:From August 2020 to March 2022, 12 patients with soft tissue defects in 35 digits were treated in Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Ten patients were male and 2 were female, aged 25 to 58 years old. Of the patients, 1 had soft tissue defects in 5 digits, 3 in 4 digits, 2 in 3 digits and 6 in 2 digits. The size of defects was from 1.2 cm ×1.2 cm to 7.0 cm×3.5 cm after debridement. The vascular perforators discovered from intraoperative explorations were found originating from the superficial peroneal artery in 24 flaps, from the peroneal artery in 7 flaps and from the anterior tibial artery in 4 flaps. During surgery, the perforator artery and accompanying veins of the flaps were anastomosed with the proper digital artery and palmar or dorsal subcutaneous veins in the recipient site, respectively. The size of the flaps was from 1.5 cm×1.5 cm to 7.5 cm×4.0 cm. No nerve was affected in the surgery. The wound at donor sites in the calf was sutured directly. Regular postoperative follow-ups were conducted at outpatient clinics. The comprehensive evaluation scale of flap was used to assess the conditions of the donor and recipient sites.Results:In this study, all 35 soft tissue defects of digits in 12 patients were reconstructed by the anterolateral perforator flaps of calf. All the 35 flaps survived after surgery, with a 100% of survival rate. The patients were instructed to carry out early functional training after surgery. Follow-up lasted 6 to 24 months, with an average of 11 months. Twenty-five flaps were found in slightly swollen, and further flap thinning surgery were carried out 3 months after the primary surgery, while the rest of the flaps had good appearance and texture. At 6 months after surgery, all flaps recovered a partial deep and shallow sensory and sense of touch. All wound at donor sites in calf had one-stage healing without dysfunction. The comprehensive evaluation scale was excellent in 28 flaps and good in 7 flaps. The excellent and good rate was 100%.Conclusion:It is an effective method to use multiple free anterolateral perforator flaps of calf to reconstruct multiple digit defects in single hand. The flaps can be conveniently harvested and the multiple digital defects in single hand can be reconstructed in primary surgery with small damages to the donor sites and together with satisfactory clinical outcomes.

OBJECTIVE:
To observe the effects of moxibustion at "Baihui" (GV 20) and "Dazhui" (GV 14) at different time points on the serum level of β-endorphin (β-EP), substance P (SP) and expression of interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) protein in brainstem in rats with migraine, and to explore the effect and mechanism of moxibustion in preventing and treating migraine.
METHODS:
Forty male SD rats were randomly divided into a blank group, a model group, a prevention+treatment (PT) group and a treatment group, 10 rats in each group. Except the blank group, the rats in the remaining groups were injected with nitroglycerin subcutaneously to prepare migraine model. The rats in the PT group were treated with moxibustion 7 days before modeling (once a day) and 30 min after modeling, while the rats in the treatment group were treated with moxibustion 30 min after modeling. The "Baihui" (GV 20) and "Dazhui" (GV 14) were taken for 30 minutes each time. The behavioral scores in each group were observed before and after modeling. After intervention, ELISA method was used to detect the serum level of β-EP and SP; the immunohistochemistry method was used to detect the number of positive cells of IL-1β in brainstem; the Western blot method was used to detect the expression of COX-2 protein in brainstem.
RESULTS:
Compared with the blank group, the behavioral scores in the model group were increased 0-30 min, 60-90 min and 90-120 min after modeling (P<0.01); compared with the model group, in the treatment group and the PT group, the behavioral scores were decreased 60-90 min and 90-120 min after modeling (P<0.01). Compared with the blank group, in the model group, the serum level of β-EP was decreased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β in brainstem and the expression of COX-2 protein were increased (P<0.01). Compared with the model group, in the PT group and and the treatment group, the serum level of β-EP was increased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β and the expression of COX-2 protein in brainstem were decreased (P<0.01, P<0.05). Compared with the treatment group, in the PT group, the serum level of β-EP was increased and COX-2 protein expression was decreased (P<0.05).
CONCLUSION
Moxibustion could effectively relieve migraine. The mechanism may be related to reduce the serum level of SP, IL-1β and COX-2 protein expression in brainstem, and increase the serum level of β-EP, and the optimal effect is observed in the PT group.

The chemical constituents from the fruits of Morinda citrifolia were systematically explored by chromatographic fractionation methods including silica gel, octadecylsilyl(ODS) gel, Sephadex LH-20 gel, and preparative high performance liquid chromatography(pre-HPLC). The chemical structures of all isolated compounds were identified on the basis of their physicochemical properties, spectroscopic analyses, as well as the comparisons of their physicochemical and spectroscopic data with the reported data in literature. As a result, 22 isolated compounds from the 90% ethanol extract of the fruits of M. citrifolia were identified, which were moricitritone(1), 2'-deoxythymidine(2), cyclo-(L-Pro-L-Tyr)(3), methyl-5-hydroxy-2-pyridinecarboxylate(4), methyl pyroglutamate(5), bisbenzopyran(6), epipinoresinol(7), 3, 3'-bisdemethyl pinoresinol(8), 3, 3'-bisdemethyltanegool(9), trimesic acid(10), crypticin B(11), kojic acid(12), vanillic acid(13), protocatechoic acid(14), 5-hydroxymethyl furfural(15), blumenol A(16), 1-O-(9Z, 12Z-octadecadienoyl) glycerol(17), mucic acid dimethylester(18), methyl 2-O-β-D-glucopyranosylbenzoate(19), 2-phenylethyl-O-β-D-glucoside(20), scopoletin(21), and quercetin(22). Among them, compound 1 was a new pyrone derivative, compounds 2, 4-7, 10-12, and 17 were isolated from the plants belonging to Morinda genus for the first time, and compound 18 was obtained from M. citrifolia for the first time. Moreover, on the basis of testing the activities of all isolated compounds on inhibiting the proliferation of synovial fibroblasts in vitro by MTS assay, the anti-rheumatoid arthritis activities of all isolated compounds were initially evaluated. The results showed that compounds 1-6, 9, 19, and 20 exhibited remarkable anti-rheumatoid arthritis activities, which displayed the inhibitory effects on the proliferation of MH7A synovial fibroblast cells with the IC_(50) values in the range of(3.69±0.08) to(168.96±0.98) μmol·L~(-1).
