Abstract
Objective: To examine the effect of adjuvant radiotherapy on postoperative complications of immediate deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. Methods: Data was collected from 185 patients underwent immediate DIEP reconstruction during November 2006 to March 2020 Department of Breast surgery, Fudan University shanghai Cancer Center. All the patients were female, aging (43.0±7.8) years (range: 29 to 61 years). The series included with a total of 187 flaps (2 bilateral, 183 unilateral). Included patients were divided into 2 groups: immediate DIEP reconstruction requring or not requring post-mastectomy radiation therapy (71 cases (71 flaps) in PMRT group, 114 cases (116 flaps) in control group). The aesthetic outcome were measured by Kroll score system and compared between the groups by t test. The complications included partial flap loss, minor necrosis were analyzed between the groups by χ2 test, while the influence of the other correlation factors on complication occurrence was analyzed by Logistic analysis. Results: The controll groups showed higher aesthetic results (2.21±0.55 vs. 2.47±0.82, t=-2.593, P=0.010). Complication rate in PMRT group was higher than that in control group (19.7% (15/71) vs. 4.2% (4/116), χ²=15.079,P<0.01). The complication rate was not correlated with age, body mass index, perforator number, neoadjuvant chemotherapy and adjuvant chemotherapy. Conclusions: Correlation was observed between adiuvant radiotherapy and post-operative complication of the DIEP flap. However, the complication occurrence and aesthetic results remain in the acceptable range. The other factors such as age, body mass index, perforator number, neoadjuvant chemotherapy and adjuvant chemotherapy should not be considered as prognosis factor of post-operative complication of the DIEP flap.

Abstract
Objective: To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China. Methods: A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ2 test was used for categorical variables. Results: A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ2=6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ²=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ2=4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×109/L vs. 10.5 (2.5-32.2)×109/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) μg/L vs. 0.24 (0.01-18.85) μg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions: The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

Abstract
The classical B1(NaCl)↔B2(CsCl) transitions have been considered as a model for general structural phase transformations, and resolving corresponding phase transition mechanisms under high strain rate shock compression is critical to a fundamental understanding of phase transition dynamics. Here, we use subnanosecond synchrotron x-ray diffraction to visualize the lattice response of single-crystal KCl to planar shock compression. Complete B1-B2 orientation relations are revealed for KCl under shock compression along ⟨100⟩_{B1} and ⟨110⟩_{B1}; the orientation relations and transition mechanisms are anisotropic and can be described with the standard and modified Watanabe-Tokonami-Morimoto model, respectively, both involving interlayer sliding and intralayer ion rearrangement. The current study also establishes a paradigm for investigating solid-solid phase transitions under dynamic extremes with ultrafast synchrotron x-ray diffraction.

Abstract
Objective: To compare the postoperative outcomes and urinary continence recovery time between standard robotic-assisted laparoscopic radical prostatectomy (RARP) and Retzius-sparing robotic-assisted laparoscopic radical prostatectomy (RsRARP). Methods: A total of 92 patients with low to intermediate-risk prostate cancer who underwent RARP (n=52) and RsRARP (n=40) in Sir Run Run Shaw Hospital from October, 2016 to January, 2018 were retrospectively reviewed. Perioperative data (operative time, estimated blood loss, complications, postoperative staging, postoperative Gleason score) and surgical outcomes (rate of margin positive, urinary continence recovery time) of RARP and RsRARP group were comparatively analyzed. Results: All 92 cases were successfully performed with robot. RARP group had a significantly shorter mean operative time when compared with that in RsRARP group ((103±23) min vs (130±26) min, P<0.05). The two groups had comparable estimated blood loss ((100±54) ml vs (103±64) ml, P>0.05), rate of postoperative infection (5.8% (3/52) vs 5.0% (2/40), P>0.05) and rate of postoperative urine leakage (3.8%(2/52) vs 2.5%(1/40), P>0.05). The two groups had a comparable rate of margin positive (7.7%(4/52) vs 12.5%(5/40), P>0.05). Compared with RsRARP group, the RARP group had a lower rate of urinary continence recovery immediately after the catheter removing at 1 week, 1 month and 3 months after the operation (all P>0.05). The two group had a comparable rate of urinary continence recovery at 6 months after the operation (P>0.05). Conclusion: The RsRARP technique has a good tumor control and obvious advantage of early urinary continence recovery compared with the standard RARP technique. RsRARP technique is safe and effective for the treatment of localized prostate cancer.

Abstract
Objective: To observe the toxic effects of different doses of baicalin on liver and kidney of rats after different time administration, and provide experimental reference for the safety of clinical medication. Methods: In April 2019, 42 Wistar male rats were randomly divided into a control group (0.9% sodium chloride solution) and baicalin administration groups (100, 200 mg/kg) , 14 rats in each group, and one was given by oral gavage. 7 times/d, 6 times/week, 7 rats in each group were sacrificed 28 and 56 days after the administration. The wet weights of liver and kidney were weighed and the organ coefficients were calculated. The hematoxylin-eosin (HE) staining was used to detect the histomorphological changes. And the levels of serum alanine aminotransferase (ALT) , aspartate aminotransferase (AST) , alkaline phosphatase (ALP) , blood urea nitrogen (BUN) and creatinine (CRE) were detected. Results: After 56 days of administration in baicalin 200 mg/kg rats, the body weight and kidney coefficient were lower than those of the control group. Histopathology showed that glomerular atrophy became smaller, renal tubules were significantly atrophied, and epithelial cell necrosis occurred. No obvious abnormalities in liver was observed. After 56 days of administration in baicalin 200 mg/kg rats, the levels of BUN and CRE in the serum were higher than those of the control group, and the differences were statistically significant (P<0.05) . There were no obvious abnormalities in the baicalin 100 mg/kg group and the 28 d of administration in baicalin 200 mg/kg group. Conclusion: Under the conditions of this test, baicalin has certain renal toxicity in male rats.

Abstract
A large field of view is normally desired for synchrotron x-ray imaging, while a small x-ray spot size is required for x-ray diffraction. A multiscale measurement system with an adjustable x-ray spot size is developed to accommodate different spot size requirements for in situ phase-contrast imaging and diffraction. The centers of a diffraction scintillator with a through-hole and an imaging scintillator are collinear with the x-ray beam. With the proof-of-principle experiments on a magnesium alloy under uniaxial tension, we demonstrate the feasibility of the multiscale measurement system for full azimuthal range diffraction measurements with improved resolution and large field of view strain field measurements via x-ray digital image correlation.

Abstract
Objective: To examine treatment outcomes of breast phyllodes tumors and the prognosis factors of local recurrence. Methods: This retrospective cohort study included 276 patients who underwent surgical resection at Breast Center, Peking University People's Hospital from January 2011 to December 2019. Tumor subtype and histopathological features were determined from pathology reports, and the deadline of follow-up was September 30th, 2020. All 276 patients underwent open surgery, including 17 patients of mastectomy, and 259 patients of lumpectomy. The enrolled patients were all female, with age of (41.5±11.3) years (rang: 11 to 76 years), and tumor diameter of 35(28) mm (M(QR)). The Kaplan-Meier method and Log-rank test were used for survival analysis. The multivariate analysis was implemented using the Cox proportional hazard model. Results: According the pathologic test, there were 191 patients of benign phyllodes tumor, 67 patients of borderline tumor and 18 patients of malignant tumor. There were 249 patients with a follow-up of more than 6 months, and 14.1% (35/249) had local recurrence. The time-to-recurrence was (28.6±22.2) months (range: 2 to 96 months), (29.1±18.1) months (range: 2 to 80 months), (32.1±30.1) months (range: 5 to 96 months) and (12.0±6.9) months (range: 8 to 20 months) for benign, borderline and malignant phyllodes tumors. Tumor diameter (≥100 mm vs.<50 mm, HR=3.968, 95%CI: 1.550 to 10.158, P=0.004) and malignant heterologous element (yes vs. no, HR=26.933, 95%CI: 3.105 to 233.600, P=0.003) were prognosis factors of local recurrence. One death from malignant phyllodes occurred after distant metastasis. The 3-year disease-free survival rates of benign, borderline and malignant phyllodes tumor were 88.2%, 81.7% and 81.4% (P=0.300). Conclusion: Phyllodes tumors have a considerable local recurrence rate, which may be associated with tumor diameter and malignant heterologous element.

Abstract
The probability of developing liver metastases in patients with colorectal cancer is 40%-50%. Liver metastases remain an important adverse factor affecting long-term prognosis of colorectal cancer patients. Surgical resection of liver metastases is the only potentially curative treatment option. After comprehensive treatment, initially unresectable liver metastases might be converted to resectable tumors. This concept is known as conversion therapy. In this review, research status of conversion therapy in colorectal cancer liver metastases was summarized, providing updated concept of resectability, discussions on the assessment of tumor response and timing of operation, debates on the influence on tumor sidedness, and latest advancement in the treatment strategy of conversion therapy. Through analyzing existing problems, we hope to offer insights into possible progress in the future and provide references for the development of clinical practice.

Abstract
Objective: To compare and analyze the diagnostic value of prostate imaging reporting and data system (PI-RADS) version 2.1 and version 2 for prostate transitional zone lesions. Methods: The imaging data of 159 patients with major prostate lesions located in the transitional zone collected by the Department of Radiology of the Second Affiliated Hospital of Suzhou University from January to December 2017 were retrospectively analyzed. Two radiologists used PI-RADS V2.1 and V2 scoring system respectively to perform diagnostic scores on the enrolled cases. The weighted Kappa test was used to evaluate the consistency of PI-RADS V2.1 and V2 scores between the two radiologists. The receiver operating characteristic (ROC) curve was used to evaluate and compare the diagnostic efficiency of two radiologists using two scoring systems for transitional zone prostate cancer (PCa) and clinically significant PCa (csPCa). Results: The weighted Kappa values between the scores of all lesions, benign lesions, PCa lesions, and csPCa lesions by the two radiologists using PI-RADS V2.1 and V2 scoring systems were 0.754, 0.643, 0.734, 0.782 and 0.808, 0.738, 0.775, 0.826, respectively. The PI-RADS V2.1 scoring system had a better consistency. There were no statistically significant differences in sensitivity, specificity, area under the ROC curve (AUC) between the PI-RADS V2.1 and V2 scoring system for PCa and csPCa (all P>0.05). However, in this set of data, the sensitivity and AUC value of PI-RADS V2.1 scoring system in diagnosing PCa and csPCa were higher than those of P-RADS V2. The diagnostic sensitivity of PI-RADS V2.1 and V2 for PCa were 86.7% and 80.0%, the diagnostic sensitivity for csPCa were 94.4% and 88.9%, the diagnostic AUC for PCa were 0.857 and 0.816, and the diagnostic AUC of csPCa were 0.917 and 0.886, respectively. Conclusion: The consistency of PI-RADS V2.1 in scoring prostate transitional zone lesions was better than PI-RADS V2.

Abstract
Objective: To investigate the current trend of breast cancer neoadjuvant therapy and provide reference for the improvement of breast cancer clinical guideline in the future. Methods: Questionnaires of cross-sectional survey were sent to 110 hospitals (breast cancer surgery quantity surpassing 200) between July 2018 and September 2018. The stages and subtypes, therapeutic regimen, treatment assession, operation choice and preforming of patients underwent neoadjuvant therapy were recorded. Results: Neoadjuvant treatment has been performed in all of the 110 hospitals. The total number of breast patients underwent neoadjuvant therapy was about 14 550 (17.0% in surgical patients) in 2017. For all of the neoadjuvant patients, the proportion of stageⅡ patients was less than 30% in 81 hospitals, and the proportion of stage Ⅲ was more than 50% in 84 hospitals. The numbers of estrogen receptor (ER) (+ )/human epidermal growth factor receptor-2 (HER-2) (-), ER (-)/HER-2 (+ ) and triple negative subtype breast cancer patients were 3 550 (24.4%), 6 024 (41.4%) and 4 991 (34.3%), respectively. Patient's scruples of relatively delayed operation and weak will of breast conservation after neoadjuvant therapy were the majority reasons for neoadjuvant therapy restriction. Anthracycline followed by taxane was the most usual neoadjuvant therapeutic regimens in 53.6% hospitals, and anthracycline plus taxane was the first choice in 42.7% hospitals. Chemotherapy with targeting therapy was recommended to HER-2 positive neoadjuvant patients in 80.9% hospitals. To assess treatment outcome of neoadjuvant treatment, 42.7% hospitals used MRI in more than 50% patients while the usage rate of MRI was less than 20% in 37.3% hospitals. The proportions of hospital using repeat-marking, tattoo and metal clip as the first method to identify the primary tumor region and lymph nodes were 60.0%, 29.1% and 10.9%, respectively. Breast-conservation rate after neoadjuvant therapy was less than 20% in 87.3% hospitals. Conclusions: Neoadjuvant therapy for breast cancer is widely performed in most hospitals in China, while the proportion of neoadjuvant treatment in patients with operable breast cancer is still low. Meanwhile, the idea of achieving de-escalation operation through neoadjuvant treatment is not promoted and the therapeutic evaluation method of neoadjuvant treatment needs further studies to improve.

Abstract
1. Eggshell quality is important for the poultry industry. Calcium is deposited during eggshell formation, and protein kinase C alpha (PRKCA) is involved in transmembrane transport of calcium ions in cells. However, the biological function of PRKCA in poultry is still not understood. Therefore, the aim of this study was to explore the association of mRNA expression and single nucleotide polymorphisms (SNPs) of the PRKCA gene with eggshell quality in laying ducks. 2. The mRNA expression and SNPs of the PRKCA gene were detected by real-time fluorescence quantitative PCR (qRT-PCR) and sequencing of PCR products in 45-week-old female Sansui ducks, which is a high production layer duck breed in China. The association of mRNA expression and SNPs in the PRKCA gene with layer duck eggshell traits was analysed using SPSS (v18.0) software. 3. The results demonstrated that PRKCA mRNA was widely expressed in all examined tissues, and expression was highest in kidney and lowest in the gizzard. Furthermore, the PRKCA mRNA level in uterus was significantly positively correlated with eggshell strength and eggshell weight (P < 0.05). Three novel SNPs, the synonymous mutations of g.9571770 T > C in exon 5, g.9583222 C > T and g.9583227 G > A in exon 7, were found in the PRKCA gene, giving four haplotypes and 10 diplotypes, which affected the mRNA secondary structure and free energy. The g.9583222 C > T and g.9583227 G > A mutations were significantly associated with eggshell strength (P < 0.05). Diplotype H1H1 was advantageous for increasing the strength and thickness of an eggshell. 4. In conclusion, the study showed that the mRNA transcription and genetic variation in the PRKCA gene could significantly affect the strength of duck eggshell and that the PRKCA gene is an important candidate gene for improving eggshell quality in poultry.

Abstract
Tibial dyschondroplasia (TD) is an intractable avian cartilage disease in which proximal growth plates of tibia lack blood vessels and contain nonviable cells, and it leads to the inflammatory response. Prostaglandins (PGs) genes have not been studied yet in TD chicken, and they might play role in skeletal metabolism, therefore we planned to explore the role of recombinant glutathione-S-transferase A3 (rGSTA3) protein and PG-related genes. In this study, qRT-PCR, enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) analysis were used to identify the expression patterns of eight PG-related genes in the tibial growth plate of broiler chicken. The results showed that the expression of PG-related genes glutathione-S-transferase A3 (GSTA3), cyclooxygenase 2 (COX-2), prostaglandin D2 synthase (PTGDS), prostaglandin E synthase (PTGES), prostaglandin E2 receptor (PTGER) 3, PTGER4, prostaglandin reductase 1 (PTGR1) and hematopoietic prostaglandin D synthases (HPGDS) expression were identified and could significantly respond to thiram-induced TD chicken. Interestingly, the expression of rate-limiting enzyme COX-2 and PGE2 were induced after the treatment of rGSTA3 protein. These findings demonstrated that the occurrence of TD is closely related to the inhibition of PGs. Moreover, rGSTA3 protein participated in the recovery of TD by strengthening the expression of PG-related genes.

Abstract
Abstract Cantharidin poisoning has been proven to cause multiple organ damage. Acute circulatory failure, acute renal failure, and multiple organ failure resulting from cantharidin poisoning are the main causes of death for patients with cantharidin poisoning. However, research on the damage of main target organs and mechanism of cantharidin poisoning is not clear. This paper reviews the latest toxicological and pathological research literatures at home and abroad related to cantharidin poisoning and comprehensively summarizes the latest research progress on the toxicological and pathological damage and mechanism of the digestive system, circulatory system, respiratory system, urinary system, reproductive system, skin mucosa, immune system, and nervous system after cantharidin poisoning, to provide reference for improving the molecular toxicological mechanism of cantharidin poisoning and decision-making in the clinical intervention of cantharidin poisoning.

Abstract
Objective: Mesenteric fat hypertrophy is present in about a quarter of Crohn's disease (CD) patients and it can be easily detected by bowel ultrasound (US). The purpose of this research was to assess the correlation between mesenteric fat hypertrophy and behavior and activity of CD. Methods: A total of 89 CD patients who admitted to the First Affiliated Hospital of Nanjing Medical University from August 2018 to November 2019 were recruited in this study. The total CD patients were divided into two groups depending on with or without mesenteric fat hypertrophy by US tests. Crohn's disease activity index (CDAI), simplified endoscopic score for Crohn's disease (SES-CD), serum inflammatory indicators and fecal calprotectin were assessed. Results: Mesenteric fat hypertrophy was significantly associated with stricturing behavior (B2, P<0.01). CDAI (P=0.002) , blood platelet (P=0.001) , C-reactive protein (P=0.024) , fecal calprotectin (P=0.004) and bowel wall thickness (P<0.01) in patients with mesenteric fat hypertrophy were significantly higher than those without, but not the erythrocyte sedimentation rate (P=0.110) and SES-CD (P=0.115) . Serum albumin (P=0.001) in patients with mesenteric fat hypertrophy was lower than that in patients without mesenteric fat hypertrophy. Conclusion: Mesenteric fat hypertrophy is correlated with intestinal stenosis and disease activity in patients with Crohn's disease.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
1. The aim of this study was to investigate the effects of graded levels of dietary corn resistant starch (RS) on glucose and lipid metabolism of broilers. 2. A total of 320 male broiler chicks (Arbor Acres, one-day-old) were randomly allocated to five dietary treatments, including a corn-soybean control diet, a corn-soybean based diet containing 20% corn starch, and three diets containing 4%, 8% and 12% RS by replacing corn starch with 6.67%, 13.33% and 20% Hi-Maize® 260 (identified as control, RS1, RS2, RS3 and RS4, respectively). Each treatment contained eight replicates with eight birds, and the experiment lasted 42 days. 3. Birds fed RS diets showed lower (P < 0.05) concentrations of serum low-density lipoprotein cholesterol and non-esterified fatty acid (NEFA) at d 21 and 42 of age, compared to the control. Lower (P < 0.05) hepatic apolipoprotein B concentration and citrate synthase (CS) activity, as well as a higher (P < 0.05) glycogen synthase (GS) concentration were observed in birds fed RS diets than those in the control group at d 21 of age. Consuming RS diets linearly increased (P < 0.01) serum glucose concentration, and linearly decreased (P < 0.01) NEFA concentrations in broilers at d 21 and 42 of age. Liver GS concentration and activities of hexokinase, pyruvate and CS were linearly increased (P < 0.01) in broilers at d 21 of age, but were linearly decreased (P < 0.05) in birds at d 42 of age in response to the increase of dietary RS levels. Feeding RS diets linearly decreased (P < 0.05) mRNA expressions of PC, PPARα and CPT-1 at d 21 of age and the mRNA expressions of SREBP-1 c, ChREBP, ACC and FAS at d 42 of age, and linearly increased (P < 0.05) the mRNA expressions of PEPCK, PC, LKB1, AMPKα1, PPARα, CPT-1 and L-FABP at d 42 of age. 4. Feeding broilers with diets containing higher concentration of RS promoted hepatic lipolysis and gluconeogenesis through activated AMPK signalling pathway and accelerated whole-body energy expenditures in the grower phase.

Abstract
Glycerol is used as a bovine semen osmotic cryoprotectant that greatly improves the quality of frozen and thawed bovine sperm. However, high glycerol concentrations can have a toxic effect on frozen and thawed bovine sperm. Therefore, this experiment investigated the effect of replacing a portion of the glycerol in a cryoprotectant solution with crocin on the sperm apoptosis, protamine deficiency and membrane lipid oxidation of frozen and thawed Yanbian yellow cattle sperm. The experiment included a control group (6% glycerol) and four treatment groups: I (3% glycerol), II (3% glycerol +0.5 mM crocin), III (3% glycerol + 1 mM crocin) and IV (3% glycerol + 2 mM crocin). Computer assisted semen analysis was used to detect sperm motility, Hoechst 33,342, propidium iodide, and JC-1 staining were used to analyse sperm viability and mitochondrial membrane potential, chromomycin A3 staining was used to detect protamine deficiency and DNA damage, flow cytometry was used for sperm membrane lipid disorder detection and analysis, and real-time quantitative RT-qPCR was used to detect the mRNA expression levels of protamine-related genes (PRM2, PRM3), sperm acrosome-associated genes (SPACA3), oxidative stress-related genes (ROMO1) and apoptosis-related genes (BCL2, BAX). Compared to the control group, replacing a portion of glycerol with 1 mM crocin significantly improved sperm motility, plasma membrane integrity, membrane lipid disorders (p < .05) and viability, mitochondrial membrane potential, protamine deficiency (p < .01). The expression level of PRM2, PRM3, SPACA3 and BCL2 significantly increased (p < .05), while the expression levels of ROMO1 and BAX significantly decreased (p < .05). Accordingly, the BCL2/BAX ratio significantly increased (p < .05). In summary, the substitution of a portion of glycerol with crocin in cryoprotective solution improved the quality of Yanbian yellow cattle sperm after freezing and thawing.
