Red blood cell distribution width-to-albumin ratio is associated with all-cause mortality in cancer patients.

BACKGROUND: Cancer causes a serious health burden on patients worldwide. Chronic low-level inflammation plays a key role in tumorigenesis and prognosis. However, the role of the red blood cell distribution width (RDW)-to-albumin (RA) ratio in cancer mortality remains unclear. METHODS: In this retrospective cohort study, we collected clinical information from cancer patients from the Medical Information Mart for Intensive Care III (MIMIC-III) version 1.4 database and then calculated RA by dividing RDW by albumin concentration. The primary outcome was 30 days mortality, while secondary outcomes were 90 days and 1 year mortality. Next, we adopted Cox regression models to calculate hazard ratios (HR) together with 95% confidence intervals (CI) for all-cause mortalities associated with the RA ratio. RESULTS: For 30 days mortality, the HR (95% CI) for the high RA ratio (≥5.51) was 2.17 [95CI% (1.87-2.51); p = <0.0001], compared with the low RA ratio (<5.51). In Model 2, we adjusted sex and age and obtained HR (95% CI) of 2.17 [95CI% (1.87-2.52); p = <0.0001] for the high RA ratio (≥5.51) group, compared to that in the low RA ratio (<5.51). In Model 3, adjusting for age, sex, anion gap, hematocrit, white blood cell count, congestive heart failure, SOFA, liver disease, and renal failure resulted in HR (95% CI) of 1.74 [95CI% (1.48-2.04); p = <0.0001] for the high RA ratio (≥5.51) relative to the low RA ratio (<5.51). We also analyzed common diseases in cancer patients but found no significant association. CONCLUSION: To the best of our knowledge, this is the first study demonstrating that increased RA ratio is independently associated with increased all-cause mortality in cancer patients.

A Full Enhanced Recovery after Surgery Program in Gynecologic Laparoscopic Procedures: A Randomized Controlled Trial.

STUDY OBJECTIVE: To assess whether a full enhanced recovery after surgery (ERAS) program can further improve perioperative outcomes among patients undergoing gynecologic laparoscopic procedures relative to those receiving limited ERAS management. DESIGN: Randomized controlled trial. SETTING: Tertiary hospital, China: December 2018 to October 2019. PATIENTS: Total of 144 women scheduled for simple elective gynecologic laparoscopic surgery. INTERVENTIONS: The participants were randomized into 2 groups: full ERAS intervention or limited ERAS management (without preoperative carbohydrate loading or total intravenous anesthesia or opiate-sparing multimodal analgesia). MEASUREMENTS AND MAIN RESULTS: The primary outcome was postoperative length of stay (LOS), and the secondary outcomes included postoperative pain, time to postoperative milestones, morbidity, and in-hospital cost. Postoperative LOS for the full ERAS program showed a 1-day reduction in comparison with the limited ERAS group (median of 1.0 day vs 2.0 days, respectively; p = .001). Multivariate regression analysis identified preoperative carbohydrate loading and opioid-sparing analgesia as the independent factors for discharging on postoperative day 1. Patients in the full ERAS program reported less pain within 72 hours after surgery and had a lower narcotic consumption rate compared with those in the limited ERAS management. They also enjoyed better and faster recovery as demonstrated by the Quality of Recovery-15 scale on postoperative day 3: 137.0 (interquartile range, 126.3-141.0) for full ERAS program vs 130.0 (23.5-139.0) for limited ERAS management, respectively (p = .030). There were no significant differences between the groups regarding postoperative 30-day morbidity, readmission rate, or in-hospital cost. CONCLUSION: The addition of full ERAS management can further reduce postoperative LOS and improve patients' quality of life after laparoscopic surgery for gynecologic diseases.

CX3CR1 regulates angiogenesis and activation of pro-angiogenic factors and triggers macrophage accumulation in experimental hepatopulmonary syndrome model.

OBJECTIVE: Prevalence of hepatopulmonary syndrome (HPS) ranges from 4% to 47% in patients with cirrhosis. This study aimed to explore possible relationship between CX3CR1 and angiogenesis or macrophage accumulation in pathological process of HPS. MATERIAL AND METHODS: Wide-type C57Bl/6 mice were divided into WT-sham, WT-common bile duct ligation (WT-CBDL), WT-CBDL plus antibody (WT-CBDL+Ab) and WT-CBDL plus Bevacizumab. The CX3CR1GFP/GFP mice were grouping into CX3CR1 GFP/GFP-sham, CX3CR1 GFP/GFP-CBDL and CX3CR1 GFP/GFP-CBDL+Bevacizumab group. Intrapulmonary expression of Akt, pAkt, ERK, pERK, iNOS, VEGF, PDGF was measured using biological technology. Hematoxylin-eosin (H&E) staining and immunohistochemical analysis were used to evaluate changes of pulmonary tissues including pathological abnormality, angiogenesis and macrophage accumulation. RESULTS: Blockade CX3CR1 pathway inhibited angiogenesis, macrophage accumulation and pathological changes of lung tissues. Blockade of CX3CR1 pathway reduced pAkt, pERK, iNOS, PDGF and VEGF activation. CX3CR1 contributed to the process of angiogenesis and activate the pro-angiogenic factors. CX3CR1 deficiency obviously reduced the macrophage accumulation. Inhibition of VEGF by Bevacizumab improved intrapulmonary angiogenesis and pathological changes of lung tissues. Inhibition of VEGF by Bevacizumab retarded the production of pAKt, PDGF, and iNOS. Inhibition of VEGF by Bevacizumab reduced CX3CL1 production. CONCLUSION: CX3CR1 could regulate the angiogenesis and activation of pro-angiogenic factors, including pAKT, pERK, iNOS, VEGF and PDGF in the process of hepato-pulmonary syndrome. Moreover, CX3CR1 could also contribute to the macrophage accumulation.

Analysis of the role of the human papillomavirus 16/18 E7 protein assay in screening for cervical intraepithelial neoplasia: a case control study.

BACKGROUND: Cervical cancer is the second-most common gynecological cancer, early screening plays a key role in the diagnosis and treatment of cervical intraepithelial neoplasia (CIN). Sustained E7 protein expression is the pathological basis for CIN and cervical cancer. METHODS: We collected the cervical cell samples of women who visited the gynecological clinic of Peking Union Medical College Hospital between September 2018 and September 2019 and submitted them to the high-risk human papillomavirus (Hr-HPV) test. We performed a magnetic particle-based chemiluminescence enzyme immunoassay to analyze the HPV16/18 E7 protein level in CIN of different severities and compared the results with those of cervical pathology (gold standard) and the HPV test. RESULTS: The positive rate of HPV16/18 E7 protein increased with the severity of CIN: 26.6% in normal tissue, 58.3% in CIN1, and 70.6% in CIN2 or higher (CIN2+). For CIN2+, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the E7 protein were 70.6, 67.9, 52.2, and 82.3%, respectively. These values of the HPV test were 86.8, 44.5, 43.7, and 87.1%, respectively. With the combination of the E7 protein assay and HPV test, the specificity for diagnosing CIN2+ was 78.1%, which was significantly higher than that of the HPV test alone. CONCLUSIONS: HPV16/18 E7 protein level is correlated with the severity of CIN and has a high concordance rate with the pathological result. For cervical cancer screening, the combination of HPV16/18 E7 protein assay and HPV test improves the CIN diagnostic specificity, detection rate, and detection accuracy.

Comparison of the impact of single-port laparoscopic and conventional laparoscopic ovarian cystectomy on the ovarian reserve in adult patients with benign ovarian cysts.

Objective: The surgical approach, hemostatic approach, histologic findings, and cyst size and location may have a role in reducing the ovarian reserve. The aim of this study was to investigate the impact of single-port laparoscopic cystectomy (SLC) and conventional laparoscopic cystectomy (CLC) on the ovarian reserve based on serum anti-Mullerian hormone (AMH) concentrations.Material and methods: This non-randomized concurrent control trial enrolled 79 female patients aged 18-45 years with benign ovarian cysts, including 47 patients in the SLC group and 32 patients in the CLC group. Outcome measures, including hospital stay, operative time, blood loss, analgesic use, body temperature, hospitalization cost, and serum AMH concentration, were evaluated preoperatively, two to three days postoperatively, and four to six weeks postoperatively.Results: The reduction in the AMH concentration after cystectomy was significantly different preoperatively, two to three days postoperatively (p < .001), and four weeks postoperatively (p < .001) regardless of the surgical approach (SLC or CLC) [F (1.00,31.00) = 0.026, p = .873]. Moreover, the hemostatic approach and histologic findings yielded significant differences in the serum AMH concentration regardless of the surgical approach (p < .05). The serum AMH concentration was higher in unilateral cysts (2.70 ± 1.80 ng/mL) than in bilateral cysts (1.73 ± 1.11 ng/mL) postoperatively (p < .05). In the SLC group, the serum AMH concentration in the patients with ovarian endometriomas (1.58 ± 1.39 ng/mL) was significantly lower than that in the patients with other cysts (3.22 ± 1.68 ng/mL) postoperatively (p < .05).Conclusion: The serum AMH concentration decreased over time postoperatively but did not significantly differ between SLC and CLC.

The Predictive Value of Potential Hematological Biomarkers in Acute Coronary Syndrome.

BACKGROUND: To explore the predictive value of potential hematological biomarkers in acute coronary syndrome (ACS). METHODS: A total of 309 patients suffering ACS from June 2014 to June 2016 in The First Affiliated Hospital of Anhui Medical University were enrolled. The clinical data was studied retrospectively. All patients were divided into 3 groups based on the presence of elevated ST-segment including UA (150), STEMI (159), and NSTEMI (100). The association between potential hematological biomarkers of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), white blood cell count (WBC), monocyte percentage (MO), and platelet width (PLW) and outcome of ACS including cTnI, occlusion of coronary artery, emergent PCI, and 30-day mortality was performed. RESULTS: Mean ± standard deviation was used to describe quantitative data of normal distribution. Inter-group comparison was performed by t or chi-square test and non-parametric test. M (P25, P75) was used to describe quantitative data of skewed distribution. Non-parametric tests revealed, except for PLW, there was significance between NLR, PLR, MO, and WBC and emergent PCI as well as 30-day mortality (p < 0.05). Multivariate logistic regression revealed that NLR was the best predictive factor of 30-day mortality. Meanwhile, it was found that the association between NLR, PLR, WBC, and cTnI was significant (p < 0.05). CONCLUSIONS: NLR is a useful and available factor in predicting outcome of ACS and more significant when combined with PLR, MO, and WBC.

Transvaginal Natural Orifice Transluminal Endoscopic Surgery for Tubal Pregnancy and a Device Innovation from Our Institution.

Natural orifice transluminal endoscopic surgery (NOTES) is a relatively new technique currently being studied around the world. Between June 2015 and June 2017, 12 patients diagnosed with ectopic pregnancy underwent transvaginal NOTES to remove their fallopian tubes. All 12 surgeries were completed successfully. The median age of patients was 33years (range, 28-42), and the median body mass index was 23.47 (range, 20.55-27.68). The median duration of amenorrhea was 53days (range, 41-60). The median serum ß-human chorionic gonadotropin was 8887 U/mL (range, 392-25 695). The median ectopic mass longest diameter was 2.95 cm (range, 2.1-5.0). The median surgical time was 47.5 minutes (range, 40-70). The median hemoperitoneum was 52.5 mL (range, 20-300), and the median blood loss was 7.5 mL (range, 2-20). Our study has proven the feasibility and repeatability of transvaginal NOTES for less difficult ectopic pregnancies. The success of transvaginal NOTES lies in the choice of patients and the establishment of the transvaginal operating platform. We added a plastic ring between the inner and outer rings outside the wound retractor. The modified platform can lessen the technical difficulties of performing transvaginal NOTES and broaden its applicability to other procedures.

Design of Sparse FIR Decision Feedback Equalizers in MIMO Systems Using Hybrid l1/l2 Norm Minimization and the OMP Algorithm.

In this paper, a novel scheme using hybrid l1/l2 norm minimization and the orthogonal matching pursuit (OMP) algorithm is proposed to design the sparse finite impulse response (FIR) decision feedback equalizers (DFE) in multiple input multiple output (MIMO) systems. To reduce the number of nonzero taps for the FIR DFE while ensuring its design accuracy, the problem of designing a sparse FIR DFE is transformed into an l0 norm minimization problem, and then the proposed scheme is used to obtain the sparse solution. In the proposed scheme, a sequence of minimum weighted l2 norm problems is solved using the OMP algorithm. The nonzero taps positions can be corrected with the different weights in the diagonal weighting matrix which is computed through the hybrid l1/l2 norm minimization. The simulation results verify that the sparse FIR MIMO DFEs designed by the proposed scheme get a significant reduction in the number of nonzero taps with a small performance loss compared to the non-sparse optimum DFE under the minimum mean square error (MMSE) criterion. In addition, the proposed scheme provides better design accuracy than the OMP algorithm with the same sparsity level.

Cyclin Y regulates the proliferation, migration, and invasion of ovarian cancer cells via Wnt signaling pathway.

This study is designated to investigate the roles of cyclin Y (CCNY) and Wnt signaling pathway in regulating ovarian cancer (OC) cell proliferation, migration, and invasion. Quantitative real-time PCR (qRT-PCR), Western blot, MTT assay, cell scratch, and transwell test were used in our study, and transplanted tumor model was constructed on nude mice. C-Myc, cyclin D1, PFTK1, ki67, OGT, and ß-catenin protein expressions in tumor tissues were detected. CCNY was significantly upregulated in OC cell lines and tissues (both P < 0.05); significant association was observed between CCNY expression and clinicopathological stage, lymph node metastasis (LNM) (P < 0.05); and the CCNY expression in stages III to IV was higher than that in stages I to II, and patients with LNM had higher CCNY expression when compared with those in patients without LNM (P < 0.05); expressions of c-Myc, cyclin D, PFTK1, ki67, and OGT were upregulated in OC tissues compared with ovarian benign tissues, suggesting that these expressions were significantly different between the two groups (P < 0.05); CCNY significantly exacerbated proliferation, migration, and invasion of A2780 cells; c-Myc and cyclin D1 protein expressions increased as the expression of CCNY increased (P < 0.001); ß-catenin expressions in A2780 cells with over-expression of CCNY were significantly increased in the nucleus, but significantly decreased in the cytoplasm (both P < 0.05); high expressions of CCNY exacerbated the proliferation of A2780 cells in nude mice and significantly increased c-Myc, cyclin D1, PFTK1, ki67, and OGT protein expressions in tumor tissues which were transplanted into nude mice (P < 0.01). CCNY might exacerbate the proliferation, migration, and invasion of OC cells via activating the Wnt signaling pathway. Thus, this study provides a theoretical foundation for the development of therapeutic drugs that are able to cure OC by targeting CCNY.

Clear cell carcinoma arising from abdominal wall endometriosis: a unique case with bladder and lymph node metastasis.

The malignant transformation of abdominal wall endometriosis is a rare event and poorly understood. Less than 30 cases have been reported in the literature. Most of the reported cases have a solitary tumor in the abdominal scar. A few cases have metastasis. Here we report a case of clear cell carcinoma in abdominal wall endometriosis with bladder and lymph system metastasis. The patient had a history of abdominal wall endometriosis and recently developed symptoms of urgent urination and inguinal mass. Physical examination and a computed tomography (CT) scan detected lymph node metastasis. CT and cystoscopy confirmed bladder involvement. The patient underwent extensive surgery and chemotherapy. Pathological analysis made a diagnosis of clear cell carcinoma with bladder and lymph node metastasis. The patient was followed up and died of the disease. Symptoms of bladder invasion and lymph node spread could be a sign of malignant transformation. Local invasion and lymph node spread are two important forms of tumor metastasis. Extensive lymph nodes metastasis might be related with poor prognosis.

Surgical Management of Pulmonary Artery Sling in a Pediatric Patient.

BACKGROUND Pulmonary artery sling (PAS) is an anatomical vascular anomaly due to the origin of the left pulmonary artery from the right pulmonary artery, which runs posteriorly between the esophagus and trachea, resulting in compression of adjacent structures. Accurate evaluation for malformation of the pulmonary artery and severity of airway obstruction is essential to surgical strategy. This report presents the diagnosis and surgical management of pulmonary artery sling in a 12-year-old boy. CASE REPORT A 12-year-old boy had chest tightness and wheezing after exercise for 6 years. He was diagnosed with PSA based on findings from imaging tests, demonstrating the left pulmonary artery originated from the middle of the right pulmonary artery and the tracheal carina was located at the site of the T6 thoracic vertebra. The main bronchus and esophagus were compressed by the left pulmonary artery due to its ectopic origin. Then, after comprehensive preoperative assessment, the patient underwent surgical repair of PAS. CONCLUSIONS This report highlights the importance of pulmonary artery sling diagnosis, imaging, and surgical planning, and the role of a multidisciplinary team in preoperative and postoperative patient management. An individualized strategy based on the preoperative assessment, intraoperative coordination among cardiologists, surgeons, and perfusionists, and careful postoperative management are the core elements for successful PAS repair.

The postmortem diagnosis of an Armillifer infection case in a cynomolgus macaque (Macaca fascicularis).

Armillifer moniliformis belongs to the order Porocephalida and family Porocephalidae, and it can cause zoonotic pentastomiasis. A suspected parasitic infection was incidentally discovered in the abdominal cavity of a cynomolgus macaque that died of persistent diarrhea. 18S rDNA amplification and sequencing revealed a high similarity (99.83%) to the Armillifer moniliformis Guangxi isolate. The isolated parasite was named the Armillifer moniliformis Yunnan isolate (GenBank accession no. HM048870). Our report presents a case of Armillifer moniliformis infection in macaques. The results indicated that early quarantine and diagnosis should be employed for animal health.

Risk factors for prolonged postoperative ICU stay in the patients with Stanford type A aortic dissection.

OBJECTIVE: To investigate the independent risk factors for postoperative prolonged ICU stay in patients with Stanford type A aortic dissection (TAAD) and assess the clinical outcomes of prolonged ICU stay. METHOD: The clinical data of 100 patients with TAAD admitted to the Department of Cardiovascular Surgery, First Affiliated Hospital of Anhui Medical University from December 2018 to September 2022 were retrospectively collected and analyzed. Patients were divided into two groups, based on the postoperative ICU stay (7 days as the threshold), regular ICU stay group (< 7 days) and prolonged ICU stay group (≥ 7 days). First, preoperative and intraoperative materials were collected for univariate analysis. Then, the significant variables after univariate analysis were analyzed using logistic regression, and the final independent risk factors for prolonged ICU stay were determined. Meanwhile, the postoperative clinical outcomes were analyzed with the aim of assessing the clinical outcomes due to prolonged ICU stay. RESULTS: There were 65 and 35 patients in the regular ICU stay group and the prolonged ICU stay group, respectively. In accordance with the result of univariate analysis in the two groups, emergency surgery (χ2 = 13.598; P < 0.001), preoperative urea nitrogen (t = 3.006; P = 0.004), cardiopulmonary bypass (CPB) time (t = 2.671; P = 0.001) and surgery time (t = 2.630; P = 0.010) were significant. All significant variates were analyzed through logistic regression, and it was found that emergency surgery (OR = 0.192; 95% CI: 0.065-0.561), preoperative urea nitrogen (OR = 0.775; 95% CI: 0.634-0.947) and cardiopulmonary time (OR = 0.988; 95% CI: 0.979-0.998) were independent risk factors for prolonged postoperative ICU stay. The Receiver Operating Characteristic (ROC) curves of these three factors were also effective in predicting postoperative prolonged ICU stay (Emergency surgery, AUC = 0.308, 95% CI: 0.201-0.415; Preoperative urea nitrogen, AUC = 0.288, 95% CI: 0.185-0.392; cardiopulmonary time, AUC = 0.340, 95% CI: 0.223-0.457). Moreover, compared with a single factor, the predictive value of combined factors was more significant (AUC = 0.810, 95% CI: 0.722-0.897). For the comparison of postoperative data in the two groups,, compared with the regular ICU stay group, the incidence of adverse events in the prolonged ICU stay group increased significantly, including limb disability of limbs (χ2 = 22.182; P < 0.001), severe organ injury (χ2 = 23.077; P < 0.001), tracheotomy (χ2 = 17.582; P < 0.001), reintubation (χ2 = 28.020; P < 0.001), 72 h tracheal extubation after surgery (χ2 = 29.335; P < 0.001), 12 h consciousness recovery after surgery (χ2 = 18.445; P < 0.001), ICU re-entering (χ2 = 9.496; P = 0.002) and irregular discharging (χ2 = 24.969; P < 0.001). CONCLUSION: Emergency surgery, preoperative urea nitrogen, and CPB time are risk factors for postoperative prolonged ICU stay after TAAD surgery. Furthermore, prolonged ICU stay is associated with worse clinical outcomes. Hence, a reasonable strategy should be adopted proactively focusing on the risk factors to shorten ICU stays and improve clinical outcomes.

Cloning, expression analysis, and molecular modeling of the gamma-aminobutyric acid receptor alpha2 subunit gene from the common cutworm, Spodoptera litura.

Intensive research on the molecule structures of the gamma-nminobutyric acid (GABA) receptor in agricultural pests has great significance to the mechanism investigation, resistance prevention, and molecular design of novel pesticides. The GABA receptor a2 (SlGABARα2) subunit gene in Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) was cloned using the technologies of reverse transcription PCR and rapid amplification of cDNA ends. The gemonic DNA sequence of SlGABARα2 has 5164 bp with 8 exons and 7 introns that were in accordance with the GT-AG splicing formula. The complete mRNA sequence of SlGABARα2 was 1965 bp, with an open reading frame of 1500 bp encoding a protein of 499 amino acids. The GABA receptor is highly conserved among insects. The conserved regions include several N-glycosylation, Oglycosylation, and phosphorylation sites, as well as 4 transmembrane domains. The identities that SlGABARα2 shared with the GABA receptor a2 subunit of Spodoptera exigua, Heliothis virescens, Chilo suppressalis, Plutella xylostella, Bombyx mori ranged from 99.2% to 87.2% at the amino acid level. The comparative 3-dimensional model of SlGABARα2 showed that its tertiary structure was composed of 4 major α-helixes located at the 4 putative transmembrane domains on one side, with some ß-sheets and 1 small α-helix on the other side. SlGABARα2 may be attached to the membrane by 4 α-helixes that bind ions in other conserved domains to transport them through the membrane. The results of quantitative real time PCR demonstrated that SlGABARα2 was expressed in all developmental stages of S. litura. The relative expression level of SlGABARα2 was the lowest in eggs and increased with larval growth, while it declined slightly in pupae and reached the peak in adults. The expressions of SlGABARα2 in larvae varied among different tissues; it was extremely high in the brain but was low in the midgut, epicuticle, Malpighian tube, and fat body.

The optimal diagnosis and treatment of intravenous leimyomatosis.

Intravenous leiomyomatosis (IVL) is a rare form of gynaecological- uterine leiomyoma. Clinically, the diagnosis and treatment are more difficult and challenging due to occult symptoms and clinical presentations, which can be similar to other common diseases. In this report, comprehensive management of a case of IVL is reported and discussed, with the aim of sharing our academic and clinical experience to improve the medical management of IVL.

Assisted Da Vinci robotic surgery combined with 3D printing technology applied in septal myectomy.

Generally, the standard surgical route of Morrow begins with the incision of median sternal, which leads to more trauma, pains and discomforts to patients with hypertrophic obstructive cardiomyopathy (HOCM). It is more difficult and rough to perform the competed resection of hypertrophic myocardium due to complicated anatomical morphology of left ventricular outflow tract and limited visual field of left ventricle during surgery. As the novel surgical strategy, firstly, under the guiding of 3D printing technology, the platform of effective preoperative evaluation focusing on how to resect the hypertrophic myocardium is established. Then, combined with assisted Da Vinci robotic surgery system, the outcome of patient with HOCM is positive and promised.

Acute effects of blood flow restriction with whole-body vibration on sprint, muscle activation and metabolic accumulation in male sprinters.

Purpose: The aim of this study was to explore the acute effects of Blood Flow Restriction Training (BFRT), Whole-Body Vibration (WBV), and BFRT + WBV on the 20 m sprint, muscle activation, and metabolic accumulation in male sprinters. Method: Sixteen male sprinters randomly performed BFRT, WBV, or BFRT + WBV interventions with 72 h intervals. Electromyography (EMG) signals were collected before and during interventions. Fingertip blood was taken before, immediately after, and 15 min after the intervention. 20 m sprint was performed before and 3 min after the intervention. Results: 1) 0-10m and 0-20 m sprint performance were significantly improved after WBV and BFRT + WBV interventions (p < 0.05), 0-20 m sprint performance was significantly improved after all three interventions (p < 0.05), 2) After BFRT + WBV intervention, the EMG amplitude of the vastus lateralis and soleus were significantly improved. Greater increases in EMG activity of the tibialis anterior muscle (p < 0.05)and blood lactate (p < 0.05)were observed following BFRT intervention compared to BFRT + WBV intervention. Conclusion: For sprint performance, BFRT and WBV had similar post-activation enhancement effects to BFRT + WBV, and the metabolic accumulation immediately following the BFRT were higher than that following BFRT + WBV in male sprinters.
