ABSTRACT

@#Objective    To explore the effect of continuous nursing on lung transplant patients at home based on humanistic care. Methods    According to hospitalization order, patients who received lung transplantation in our hospital from January 2016 to October 2020 were divided into a control group and a nursing group. The control group was treated with routine lung transplantation education and regular follow-up after discharge, and the nursing group received humanistic care during follow-up, health education at discharge, cultural exchange activities, and home care plans. After discharge, the self-management ability at home, medication adherence and satisfaction of home care between the two groups were campared. Results    A total of 60 patients were included in the study. There were 23 patients in the control group, including 16 males and 7 females, with an average age of 58.70±11.00 years. There were 37 pateints in the nursing group, including 25 males and 12 females, with an average age of 57.90±13.20 years. The scores of self-management ability at home of the nursing group (self-concept 27.41±2.37 points vs. 21.78±3.54 points; self-care responsibility 20.73±1.63 points vs. 16.83±2.79 points; self-care skills 41.46±3.77 points vs. 28.26±4.11 points; health knowledge level 57.95±4.10 points vs. 44.87±5.79 points) were higher than those in the control group (all P<0.05). The medication adherence (7.47±0.46 points vs. 6.87±0.28 points) and satisfaction of home care (23.80±1.20 points vs. 20.50±1.90 points) in the nursing group were higher than those in the control group (both P<0.05). Conclusion    Continuous nursing based on humanistic care for lung transplant patients can effectively improve the self-management ability, medication adherence and nursing satisfaction of patients after discharge.

ABSTRACT

Objective:To construct a real-time artificial intelligence (AI)-assisted endoscepic diagnosis system based on YOLO v3 algorithm, and to evaluate its ability of detecting focal gastric lesions in gastroscopy.Methods:A total of 5 488 white light gastroscopic images (2 733 images with gastric focal lesions and 2 755 images without gastric focal lesions) from June to November 2019 and videos of 92 cases (288 168 clear stomach frames) from May to June 2020 at the Digestive Endoscopy Center of Renmin Hospital of Wuhan University were retrospectively collected for AI System test. A total of 3 997 prospective consecutive patients undergoing gastroscopy at the Digestive Endoscopy Center of Renmin Hospital of Wuhan University from July 6, 2020 to November 27, 2020 and May 6, 2021 to August 2, 2021 were enrolled to assess the clinical applicability of AI System. When AI System recognized an abnormal lesion, it marked the lesion with a blue box as a warning. The ability to identify focal gastric lesions and the frequency and causes of false positives and false negatives of AI System were statistically analyzed.Results:In the image test set, the accuracy, the sensitivity, the specificity, the positive predictive value and the negative predictive value of AI System were 92.3% (5 064/5 488), 95.0% (2 597/2 733), 89.5% (2 467/ 2 755), 90.0% (2 597/2 885) and 94.8% (2 467/2 603), respectively. In the video test set, the accuracy, the sensitivity, the specificity, the positive predictive value and the negative predictive value of AI System were 95.4% (274 792/288 168), 95.2% (109 727/115 287), 95.5% (165 065/172 881), 93.4% (109 727/117 543) and 96.7% (165 065/170 625), respectively. In clinical application, the detection rate of local gastric lesions by AI System was 93.0% (6 830/7 344). A total of 514 focal gastric lesions were missed by AI System. The main reasons were punctate erosions (48.8%, 251/514), diminutive xanthomas (22.8%, 117/514) and diminutive polyps (21.4%, 110/514). The mean number of false positives per gastroscopy was 2 (1, 4), most of which were due to normal mucosa folds (50.2%, 5 635/11 225), bubbles and mucus (35.0%, 3 928/11 225), and liquid deposited in the fundus (9.1%, 1 021/11 225).Conclusion:The application of AI System can increase the detection rate of focal gastric lesions.

ABSTRACT

Objective:To search for valuable laboratory indexes of early diagnosis of anastomotic leakage after anterior resection for rectal carcinoma.Methods:From Sep 2017 to Jan 2019, 128 patients with colorectal cancer underwent anterior rectal resection at the Department of Colorectal & Anal Surgery, the 940 Hospital of the Joint Logistics Support Force.Results:Anastomotic leakage occurred in 16 of 128 patients (12.5%). Definite diagnosis of anastomotic leakage was made on between 2nd and 9th day, postopera tively averagign (6.13±2.00) days. Tumor location was a risk factor for anastomotic leakage with the incidence significantly lower when the distance from the lower edge of the tumor to the anal margin >7 cm than when the distance ≤7 cm ( χ 2=6.022, P=0.014). The percentage of increase in peripheral blood leukocytes, neutrophils, serum interleukin-6, C-reactive protein and procalcitonin in patients 3-5 days after surgery significantly related to the occurrence of anastomotic leakage (all P<0.05). The area under the working characteristic curve of the subjects with the percentage of C-reactive protein, procalcitonin, interleukin-6, leukocytes and neutrophils from the 3rd to the 5th day after operation was greater than 0.5. Conclusion:C-reactive protein, procalcitonin, interleukin-6, leukocyte and neutrophil percentage are risk factors predicting anastomotic leakage after anterior resection of rectal cancer.

ABSTRACT

Objective:To investigate the feasibility and early clinical efficacy of spherical motion axis hinge knee prosthesis to reconstruct distal femoral bone defects.Methods:A retrospective analysis was performed on 16 patients admitted to PLA 960th Hospital and Tianjin Hospital from October 2019 to November 2021, including 8 males and 8 females, with an average age of 43.3±17.8 years (range, 15-71 years). There were 13 patients of primary tumors of the distal femur and 3 patients of postoperative revision of knee joint prostheses. Among the 13 patients with distal femur tumors, there were 6 cases of osteosarcoma, 5 cases of giant cell tumor of bone, 1 case of leiomyosarcoma and 1 case of chondrosarcoma. The reasons for revision after prosthesis replacement in 3 cases were: 2 cases of aseptic loosening after tumor-type prosthesis and 1 case of periphery fracture of surface artificial knee prosthesis. A spherical shaft rotary hinged knee prosthesis was designed and fabricated to reconstruct postoperative femoral defects in 16 patients. Follow up regularly after the operation, recheck the X-ray film to evaluate the lower limb force line, evaluate the quality of life after the operation with the Chinese version of 36-item short-form (SF-36), and evaluate the postoperative limb function with the Musculoskeletal Tumor Society (MSTS) 93 evaluation system.Results:All 16 patients were successfully placed with prostheses, and except for 2 patients undergoing total femoral replacement, the length of bone defects was 18.2±11.7 cm (range, 8.6-47.1 cm) in other 14 patients, and the operation time was 138±19 min (range, 110-170 min), the intraoperative blood loss was 211±118 ml (range, 100-500 ml). The postoperative full length orthostatic X-ray film of the lower limbs showed that the distance between the mechanical axis of the lower limb and the center of the knee joint was 0.1 (0, 0.7) cm in 16 patients, and the hip-knee ankle angle was 179.0°±2.3°(range, 173.3°-182.2°). The patients were followed up for 12-36 months. No prosthesis complications were found in 16 patients. The SF-36 score was 56.7±7.0 (range, 42.7-67.4) for physiological function and 54.1±7.6 (range, 40.5-66.3) for psychological function. The maximum knee flexion angle was 120.0°±15.6° (range, 95°-130°). The MSTS 93 score of 15 patients with tumor was 25.0±1.7 (range, 22-28), including 7 excellent and 8 good. One patient developed liver and lung metastases 10 months after surgery and died 18 months after surgery. The remaining patients, as of the last follow-up, were alive and had no local recurrence or distant metastases. Tumor-free survival time was 25.8±8.4 months (range, 12-36 months).Conclusion:The spherical motion axis hinge knee prosthesis reconstruction for distal femoral bone defects is simple and fast in intraoperative prosthesis installation, and there are no prosthetic related complications during short-term follow-up. The clinical efficacy is satisfactory.

ABSTRACT

Congenital bilateral absence of the vas deferens (CBAVD) is observed in 1%-2% of males presenting with infertility and is clearly associated with cystic fibrosis transmembrane conductance regulator (CFTR) mutations. CFTR is one of the most well-known genes related to male fertility. The frequency of CFTR mutations or impaired CFTR expression is increased in men with nonobstructive azoospermia (NOA). CFTR mutations are highly polymorphic and have established ethnic specificity. Compared with F508Del in Caucasians, the p.G970D mutation is reported to be the most frequent CFTR mutation in Chinese patients with cystic fibrosis. However, whether p.G970D participates in male infertility remains unknown. Herein, a loss-of-function CFTR p.G970D missense mutation was identified in a patient with CBAVD and NOA. Subsequent retrospective analysis of 122 Chinese patients with CBAVD showed that the mutation is a common pathogenic mutation (4.1%, 5/122), excluding polymorphic sites. Furthermore, we generated model cell lines derived from mouse testes harboring the homozygous Cftr p.G965D mutation equivalent to the CFTR variant in patients. The Cftr p.G965D mutation may be lethal in spermatogonial stem cells and spermatogonia and affect the proliferation of spermatocytes and Sertoli cells. In spermatocyte GC-2(spd)ts (GC2) Cftr p.G965D cells, RNA splicing variants were detected and CFTR expression decreased, which may contribute to the phenotypes associated with impaired spermatogenesis. Thus, this study indicated that the CFTR p.G970D missense mutation might be a pathogenic mutation for CBAVD in Chinese males and associated with impaired spermatogenesis by affecting the proliferation of germ cells.

ABSTRACT

Objective:To evaluate the intelligent gastrointestinal endoscopy quality control system in gastroscopy.Methods:Fourteen endoscopists from Renmin Hospital of Wuhan University were assigned to the quality-control group and the control group by the random number table. In the pre-quality-control stage (from April 20, 2019 to May 31, 2019), data of gastroscopies performed by the enrolled endoscopists were collected. In the training stage (June 1 to 30, 2019), the quality-control group was trained in quality control knowledge and the instructions of intelligent gastrointestinal endoscopy quality control system; but the control group was only trained in quality control knowledge. In the post-quality-control stage (from July 1, 2019 to August 20, 2019), a quality report was submitted weekly to the endoscopists in the quality-control group with a review and feedback, while the control group had no quality control report. Simultaneously, the gastroscopies performed by the enrolled endoscopists were collected during the period. Changes of precancerous lesion detection rate in the two groups were compared.Results:Seven endoscopists were assigned to each group. A total of 3 446 gastroscopies were included in the pre-quality-control stage ( n=1 651, including 753 cases in the quality-control group and 898 cases in the control group) and post-quality-control stage (n=1 795, including 892 cases in the quality-control group and 903 cases in the control group). The detection rate of precancerous lesions in the quality-control group increased by 3.6% [3.3% (29/892) VS 6.9% (52/753), χ2=11.65, P<0.01], while that of the control group increased by 0.4% [3.3% (30/903) VS 3.7% (33/898), χ2=0.17, P=0.684]. Conclusion:The intelligent gastrointestinal endoscopy quality control system with a review and feedback could monitor and improve the quality of gastroscopy.

ABSTRACT

Paeonia lactiflora is an important medicinal resource in China. It is of great significance for the protection and cultivation of P. lactiflora resources to find the suitable habitats. The study was based on the information of 98 distribution sites and the data of 20 current environmental factors of wild P. lactiflora in China. According to the correlation and importance of environmental factors, we selected the main environmental factors affecting the potential suitable habitats. Then, BCC-CSM2-MR model was employed to predict the distribution range and center change of potential suitable habitat of wild P. lactiflora in the climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 during 2021-2100. The ensemble model combined with GBM, GLM, MaxEnt, and RF showed improved prediction accuracy, with TSS=0.85 and AUC=0.95. Among the 20 environmental factors, annual mean temperature, monthly mean diurnal range of temperature, temperature seasonality, mean temperature of the warmest quarter, precipitation of the wettest month, precipitation seasonality, precipitation of the driest quarter, and elevation were the main factors that affected the suitable habitat distribution of P. lactiflora. At present, the potential suitable habitats of wild P. lactiflora is mainly distributed in Inner Mongolia, Heilongjiang, Jilin, Liaoning, Hebei, Beijing, Shaanxi, Shanxi, Shandong, Gansu, Xinjiang, Tibet, and Ningxia, and concentrated in the northeastern Inner Mongolia, central Heilongjiang, and northern Jilin. Under future climate conditions, the highly sui-table area of wild P. lactiflora will shrink, and the potential suitable habitat will mainly be lost to different degrees. However, in the SSP5-8.5 scenario, the low suitable area of wild P. lactiflora will partially increase in the highlands and mountains in western China including Xinjiang, Tibet, and Qinghai during 2061-2100. The distribution center of wild P. lactiflora migrated first to the northeast and then to the southwest. The total suitable habitats were stable and kept in the high-latitude zones. The prediction of the potential geo-graphical distribution of P. lactiflora is of great significance to the habitat protection and standardized cultivation of this plant in the future.

ABSTRACT

Background Gene sequencing industry is an emerging innovation-driven industry. Employees have high requirements for independent learning and innovation ability and face great professional pressure. Objective To understand the occupational stress, depression, and sleep of gene sequencing enterprise employees and to analyze the effect of occupational stress on depression and sleep. Methods From November to December 2021, occupational stress, depression, and sleep conditions of 469 workers from 34 enterprises in gene sequencing industry were surveyed by Core Occupational Stress Scale (COSS), Patient Health Questionnaire 9 (PHQ-9), and Pittsburgh Sleep Quality Index (PSQI). A total of 427 valid questionnaires were recovered with a questionnaire valid response rate of 91.04%. The relationship of occupational stress with depression or sleep was analyzed by logistic regression. Results The rates of occupational stress, depression, and sleep disorder were 27.40%, 33.50%, and 28.10%, respectively. Significant difference were found in the rates of depression and sleep disorder in different occupational stress groups (P<0.05). The results of logistic regression analysis showed that, for every 1 increase in social support score, the risk of depression increased by 1.206 (95%CI: 1.117−1.304), and the risk of sleep disorder increased by 1.143 (95%CI: 1.059−1.233). For every 1 increase in organization and reward score, the risk of developing depression increased by 1.082 (95%CI: 1.017−1.151). Mild, moderate, and severe occupational stress were all associated with a higher risk of depression in reference to no occupational stress (OR=2.535, 95%CI: 1.465−4.386; OR=3.774, 95%CI: 1.809−7.870; OR=3.823, 95%CI: 1.486−9.837). Severe occupational stress was associated with a higher risk of sleep disorder in reference to no occupational stress (OR=3.141, 95%CI: 1.233−8.006). Conclusion Occupational stress among employees in the gene sequencing industry can increase the risks of depression and sleep disorder. Enterprises need to take intervention measures and pay attention to prevention and treatment.

ABSTRACT

Objective:To evaluate the Kyoto gastritis score for diagnosing Helicobacter pylori ( HP) infection in Chinese people. Methods:A total of 902 cases who underwent 13C-urea breath test and gastroscopy at the same time at the Digestive Endoscopy center of Renmin Hospital of Wuhan University from January 2020 to December 2020 were studied retrospectively, including 345 cases of HP-positive and 557 of HP-negative. The differences of mucosal features and Kyoto gastritis score between HP-positive and HP-negative patients were analyzed. A receiver operating characteristic curve was plotted to predict HP infection by Kyoto gastritis score. Results:Compared with HP-negative patients, nodules [8.1% (28/345) VS 0.2% (1/557), χ2=86.29, P<0.001], diffuse redness [47.8% (165/345) VS 6.6% (37/557), χ2=413.63, P<0.001], atrophy [27.8% (96/345) VS 13.8% (77/557), χ2=52.90, P<0.001] and fold enlargement [69.0% (238/345) VS 36.6% (204/557), χ2=175.38, P<0.001] occurred more frequently in HP-positive patients. For predicting HP infection, nodules showed the highest specificity [99.8% (556/557)] and positive predictive value [96.6% (28/29)], diffuse redness showed the largest area under the receiver operating characteristic curve (AUC) of 0.707, and fold enlargement showed the highest sensitivity [69.0% (238/345)] and negative predictive value [76.7% (353/460)]. The Kyoto gastritis score of HP-positive patients was higher than that of HP-negative patients [2 (1, 2) VS 0 (0, 1), Z=20.82, P<0.001]. Furthermore, at an optimal threshold of 2, the AUC of the Kyoto gastritis score for predicting HP infection was 0.779. Conclusion:Nodules, diffuse redness, atrophy and fold enlargement under gastroscopy can suggest positive of HP infection, and the Kyoto gastritis score≥2 is sufficient reference to diagnose HP positive.

ABSTRACT

ObjectiveTo study the chemical structure of gardenia blue pigment and its inhibitory activity against monoamine oxidase B (MAO-B), in order to seek a potential feasible way for rational utilization and value enhancement of iridoids in Gardeniae Fructus. MethodIridoid glycosides in Gardeniae Fructus were hydrolyzed by cellulase to obtain their aglycones and reacted with amino acids. Then, the products were purified by column chromatography packed with D101 macroporous resin and preparative liquid chromatography to obtain gardenia blue pigments, and the gardenia blue pigments were identified by nuclear magnetic resonance (NMR) and mass spectrometry (MS). Benzylamine was used as the reaction substrate of MAO-B and in vitro incubated with gardenia blue pigment monomers, high performance liquid chromatography (HPLC) was employed to determine the production of benzaldehyde for evaluating the inhibitory effect of gardenia blue pigments on MAO-B, the mobile phase was methanol (A) -50 mmol·L-1 potassium phosphate buffer (B, pH 3.2) (2∶3), and the detection wavelength was 245 nm. ResultEight compounds of gardenia blue pigment A-H were synthesized and identified. In MAO-B inhibition test, compared with geniposide, the inhibitory activity of gardenia blue pigment D and E was significantly enhanced (P<0.05). Compared with the 6β-hydroxygeniposide, the inhibitory activity of gardenia blue pigment G and H was significantly enhanced (P<0.05, P<0.01). All the four gardenia blue pigments showed better MAO-B inhibitory activity than the prototype compounds. ConclusionGardenia blue pigment is a simple compound formed by one molecule of amino acid and one molecule of iridoid. Some gardenia blue pigments have better MAO-B inhibitory activity than the prototype compounds. The activity of gardenia blue pigment produced by different substrates is different, and the high-value gardenia blue pigment can be prepared based on experimental optimization, which can expand the application range of gardenia blue pigment and enrich the comprehensive utilization of iridoids from Gardeniae Fructus.

ABSTRACT

Objective: To summarize short-term postoperative complications of transanal total mesorectal excision (taTME) in the treatment of middle-low rectal cancer. Methods: A descriptive case series of cases was constructed. Clinical data of consecutive 83 patients with mid-low rectal cancer who received taTME treatment from November 2016 to April 2021 at Department of General Surgery of Beijing Friendship Hospital, Capital Medical University were collected. Among 83 patients, 58 (69.9%) were males, with a mean age of (61.4±11.8) years; 42 (50.6%) were low rectal cancer, 41 (49.4%) were middle rectal cancer. Short-term postoperative complication was defined as complication occurring within 30 days after operation. The complication was graded according to the Clavien-Dindo classification. At the same time, the morbidity of short-term postoperative complication in the first 40 patients and that in the last 43 patients were compared to understand the differences before and after passing the taTME learning curve. Results: Two patients (2.5%) were converted to laparotomy ; 78 (94.0%) completed anastomosis.While 5 (6.0%) underwent permanent stoma. The total operation time of transabdominal+ transanal procedure was (246.9±85.0) minutes, and the median intraoperative blood loss was 100 (IQR: 100) ml. Seventy-five cases (75 /78, 96.2%) underwent defunctioning stoma, including 74 cases of diverting ileostomy, 1 case of diverting transverse colostomy and 3 cases without stoma. The morbidity of complication within 30 days after operation was 38.6% (32/83), and the morbidity of complication after discharge was 8.4% (7/83). Minor complications accounted for 31.3% (26/83) and major complications accounted for 7.2% (6/83). No patient died within 30 days after operation. The incidence of anastomotic leakage was 15.4% (12/78). Eight patients (9.6%) were hospitalized again due to complications after discharge. The median postoperative hospital stay was 7 (IQR: 3) days. All the patients with minor (I-II) complications received conservative treatment. One patient with grade C anastomotic leakage was transferred to intensive care unit and received a second operation due to sepsis and multiple organ dysfunction. Two patients with paralytic ileus (Clavien-Dindo IIIa) underwent endoscopic ileus catheter placement. There were 3 patients with Clavien-Dindo III or above respiratory complications, including 1 patient with pleural effusion and ultrasound-guided puncture, 2 patients with respiratory failure who were improved and discharged after anti-infection and symptomatic treatment. One patient underwent emergency ureteral stent implantation due to urinary infection (Clavien-Dindo IIIb). The morbidity of postoperative complication in the first 40 cases was 50.0% (20/40), and that in the latter 43 cases decreased significantly (27.9%, 12/43), whose difference was statistically significant (χ(2)=4.270, P=0.039). Conclusions: The procedure of taTME has an acceptable morbidity of short-term postoperative complication in the treatment of mid-low rectal cancer. The accumulation of surgical experience plays an important role in reducing the morbidity of postoperative complication.

ABSTRACT

Rectal cancer is a great threat to the health of the Chinese people. With the continuous improvement of surgical treatment level, complication as an important indicator to measure the safety of surgery has received increasing attention from clinicians both at home and abroad. Although there are many studies on postoperative complications of rectal cancer, the morbidity of complication reported by related studies varies greatly. An important reason occurs in the limitations of retrospective research, such as incomplete medical records, unclear diagnostic criteria for some complications, incomplete follow-up records after discharge, and poor communication mechanisms among MDT members. Starting from a retrospective study on postoperative complications of rectal cancer and finding out the defects and problems in the registration of complications in each center, then clarifying the definition of various postoperative complications, so as to establish a sound and standardized registration system, and carry out prospective research, this path could be a reliable method to obtain relatively accurate postoperative complications of rectal cancer.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture on motor function and muscle state in patients with primary osteoporosis (POP).@*METHODS@#A total of 60 female patients with POP were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case dropped off). On the basis of adjusting lifestyle, caltrate was given orally in the control group, 2 pills a day for 4 weeks. On the basis of the treatment in the control group, electroacupuncture was applied at Zusanli (ST 36), Yanglingquan (GB 34), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), etc. in the observation group, with disperse-dense wave of 2 Hz/10 Hz in frequency, once every other day, 3 times a week for 4 weeks. The time of timed up-and-go test (TUGT) and the value of 10 m maximal walking speed (10 m MWS) before and after treatment were compared in the two groups, and the Young's modulus values of bilateral multifidus muscles in prone position and sitting position before and after treatment were compared by real-time shear wave elastography (SWE) in the two groups.@*RESULTS@#After treatment, the TUGT time was decreased compared before treatment in the observation group (P<0.01), and that in the observation group was shorter than the control group (P<0.01). After treatment, the value of 10 m MWS test was increased compared before treatment in the observation group (P<0.05). After treatment, the Young's modulus values of bilateral multifidus muscles in prone position and sitting position were increased compared before treatment in the observation group (P<0.01); except for the left side in sitting position, the Young's modulus values of multifidus muscles in the observation group were higher than those in the control group (P<0.01, P<0.05).@*CONCLUSION@#On the basis of oral caltrate, electroacupuncture can improve the motor function and muscle state in patients with POP.

ABSTRACT

As the first country that has been certified malaria-free in the WHO Western Pacific Region for more than 3 decades, China should share its successful experiences of malaria control and provide globally recognized anti-malaria products by making full uses of its advantages in provision and production capacity of artemisinin raw materials, to fill the gaps of international demands for mosquito nets, rapid diagnostic reagents and antimalarial compounds. Increasing the investment of research and development of antimalarial products, building overseas bases for artemisinin raw material production, establishing international regulatory authority and promoting the local production of antimalarial products are needed to further promote the internationalization of Chinese antimalarial products, so as to achieve the equity and accessibility of Chinese antimalarial products in highburden regions for malaria.

ABSTRACT

We investigated the ability of Dracocephalum moldavica (EPDM) flavonoids to protect human brain microvascular endothelial cells (HBMECs) from necroptosis induced by ischemia-reperfusion injury. To mimic the process of cerebral ischemia-reperfusion injury, a necroptosis model was established by treatment with the pan-cysteine aspartic acid protease (caspase) inhibitor Z-VAD-FMK combined with oxygen-glucose deprivation/re-oxygenation (OGD/R) injury using HBMECs. Cell proliferation and cytotoxicity (cell counting kit-8, CCK-8) was used to measure cell viability. A Hoechst33342/PI fluorescent double-staining method was exploited to determine the rate of cell necroptosis. A commercial kit was used to detect lactate dehydrogenase in the cell culture supernate. DCFH-DA probes, calcein AM and JC-1 probes were used to measure changes in ROS production, mitochondrial membrane permeability transformation pore (MPTP) opening and mitochondrial membrane potential (MMP), respectively. Enzyme-linked immunosorbent assay (ELISA) kits were chosen to detect the release of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6). Western blotting was used to detect necroptosis-related proteins. The results show that relative to control group, Z-VAD-FMK combined with OGD/R injury reduced cell viability, increased the necroptosis rate and the levels of LDH and ROS in HBMECs. The MPTP of the model group cells opened and the MMP reduced. TNF-α, IL-1β, and IL-6 levels were significantly elevated. Furthermore, the expression of receptor-interacting protein kinase 3 (RIP3) and mitochondrial phosphoglycerate mutase 5 (PGAM5) was significantly increased, accompanied by an increase of phosphorylated mixed-lineage kinase domain-like protein (p-MLKL)/MLKL. EPDM partially reversed the changes of the above-mentioned factors in HBMECs induced by Z-VAD-FMK plus OGD/R injury. These results indicate that EPDM may protect HBMECs from cerebral ischemia-reperfusion injury by inhibiting the RIP3/MLKL/PGAM5 pathway and MPTP opening to maintain mitochondrial function, thereby providing a scientific basis for the use of EPDM in the treatment of cerebral ischemia-related diseases.
