Asperuloside Promotes Apoptosis of Cervical Cancer Cells through Endoplasmic Reticulum Stress-Mitochondrial Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of asperuloside on cervical cancer based on endoplasmic reticulum (ER) stress and mitochondrial pathway.@*METHODS@#Different doses (12.5-800 µg/mL) of asperuloside were used to treat cervical cancer cell lines Hela and CaSki to calculate the half maximal inhibitory concentration (IC50) of asperuloside. The cell proliferation was analyzed by clone formation assay. Cell apoptosis, intracellular reactive oxygen species (ROS) and mitochondrial membrane potential were determined by flow cytometry. The protein expressions of cleaved-caspase-3, Bcl-2, Bax, Cyt-c, cleaved-caspase-4 and glucose-regulated protein 78 (GRP78) were analyzed by Western blot. And the inhibitor of ER stress, 4-phenyl butyric acid (4-PBA) was used to treat cervical cancer cells to further verify the role of ER stress in the apoptosis of cervical cancer cells induced by asperuloside.@*RESULTS@#Asperuloside of 325, 650, and 1300 µg/mL significantly inhibited the proliferation and promoted apoptosis of Hela and CaSki cells (P<0.01). All doses of asperuloside significantly increased intracellular ROS levels, reduced mitochondrial membrane potential, significantly reduced Bcl-2 protein expression level, and increased Bax, Cyt-c, GRP78 and cleaved-caspase-4 expressions (P<0.01). In addition, 10 mmol/L 4-PBA treatment significantly promoted cell proliferation and reduced apoptosis (P<0.05), and 650 µg/mL asperuloside could reverse 4-PBA-induced increased cell proliferation, decreased apoptosis and cleaved-caspase-3, -4 and GRP78 protein expressions (P<0.05).@*CONCLUSION@#Our study revealed the role of asperuloside in cervical cancer, suggesting that asperuloside promotes apoptosis of cervical cancer cells through ER stress-mitochondrial pathway.

But the carrying rates of enterotoxin genes (sec, sec3, seg, seh, sei, sel, sem, sen, seo and seu) were lower in infection strains than in colonization strains (P<0.05). For antibiotic resistance genes, the carrying rates of lnuA, lnuG, aadD, tetK and dfrG were significantly higher in infection strains than in colonization strains (P<0.05). The accuracy of cross-validation of the random forest model for screening pathogenic markers of S. aureus before and after screening was 69% and 68%, respectively, and the area under the curve was 0.75 and 0.70, respectively. The random forest model finally screened out 16 pathogenic markers (sem, etb, splE, sep, ser, mecA, lnuA, sea, blaZ, cat(pC233), blaTEm-1A, aph(3')-III, ermB, ermA, ant(9)-Ia and ant(6)-Ia). The top five variables in the variable importance ranking were sem (OR=0.40), etb (OR=3.95), splE (OR=1.68), sep (OR=3.97), and ser (OR=1.68).@*CONCLUSIONS@#The random forest model can screen out pathogenic markers of S. aureus and exhibits a superior predictive performance, providing genetic evidence for tracing highly pathogenic S. aureus and conducting precise targeted interventions.

Clinical features and risk factors of pulmonary hemorrhage in extremely preterm infants / 中国新生儿科杂志

Objective:To study the clinical features and risk factors of pulmonary hemorrhage in extremely preterm (EPT) infants.Methods:From February 2018 to January 2022, EPT infants admitted to NICU of our hospital and diagnosed with pulmonary hemorrhage were retrospectively assigned into the observation group and those without pulmonary hemorrhage were assigned into the control group. Univariate analysis and multivariate logistic regression analysis were used to compare the clinical features and determine risk factors of pulmonary hemorrhage in EPT infants.Results:A total of 114 EPT infants were included, including 28 cases (24.6%) in the observation group with pulmonary hemorrhage and 86 cases in the control group. Pulmonary hemorrhage mainly occurred within the first week after birth. Univariate analysis showed that the observation group had higher incidences of following events than the control group: birth asphyxia, delivery room intubation, severe respiratory distress syndrome, hyperglycemia, thrombocytopenia, severe acidosis, shock, score for neonatal acute physiology with perinatal extension-Ⅱ (SNAPPE-Ⅱ) ≥37 and the highest lactate level. Birth weight was lower in the observation group than the control group ( P<0.05). Logistic regression analysis showed that SNAPPE-Ⅱ≥37, shock and hyperglycemia were risk factors of pulmonary hemorrhage ( OR=4.081, 4.610 and 3.355, respectively, all P<0.05). The incidences of mortality and intracranial hemorrhage in the observation group were higher than the control group. The duration of mechanical ventilation in the observation group was longer than the control group ( P<0.05). No significant differences existed in the duration of nasal continuous positive airway pressure, assist mechanical ventilation and total oxygen use, the incidences of grade Ⅱ-Ⅲ bronchopulmonary dysplasia, retinopathy of prematurity and the length of hospital stay ( P>0.05). Conclusions:SNAPPE-Ⅱ≥37, shock and hyperglycemia are early risk factors for pulmonary hemorrhage in EPT infants. EPT infants with pulmonary hemorrhage have higher incidences of mortality and intracranial hemorrhage, requiring longer periods of mechanical ventilation.

Detection methods and devices of visual detection in closed tube recombinase polymerase amplification of hepatitis B virus / 医学研究生学报

ObjectiveThe traditional detection method of recombinase polymerase amplificaton (RPA) is not suitable for rapid field detection due to the complicated operation and other factors. Taking the detection of hepatitis b virus (HBV) nucleic acid as an example, it established a detection method of HBV nucleic acid isothermal amplification based on recombinase polymerase amplificaton (RPA) and designed a matching visual detection device of RPA product.MethodsFirstly, a RPA product detection device was designed, which can be used to collect images by taking photos of mobile phones and visually interpret the detection results. Secondly, RPA primers and probes were designed according to the design of HBV gene conserved sequence. Amplification efficiency of each primer pairs were compared though monitoring the RPA reaction of real-time fluorescence curve to screen the best primers and optimize the optimal reaction conditions. Visual detection sensitivity was investigated by using artificial synthesis of HBV target plasmid, and was investigated the specificity of the method by the detection of synthetic plasmid containing hepatitis c virus (HCV), human immunodeficiency virus, treponema pallidum, influenza virus, human papilloma virus DNA fragment. Thirdly, the feasibility of RPA product visualization detection device was verified by comparing with the real-time fluorescence amplification curve. Finally, RPA visual detection was performed on 20 serum DNA samples detected by real-time fluorescence PCR to evaluate the applicability of this method to the detection of actual clinical samples.ResultsThe visual detection device of RPA product was used to realize the negative and positive signals that could be detected by mobile phone photography and visual observation. The visual detection method of HBV nucleic acid RPA amplification could realize the visual detection of DNA targets as low as 1-10 copies of HBV within 30 min at 39 ℃ and had good specificity. The test results of 20 serum DNA samples were completely consistent with those of the commercially available qPCR kit, which preliminarily verified the practicability of the method and the device.ConclusionCombined the established HBV-RPA amplification system with the RPA product visualized detection device, it would be expected to develop a low-cost rapid visualization screening technology platform for HBV nucleic acid in blood.

Objective@#To investigate the clinical application value of using laminoplasty combine with short-segment pedicle screw fixation in the treatment of cervical spine trauma patients with ossification of posterior longitudinal ligament (OPLL).@*Methods@#Fifty-four cervical spine trauma patients with OPLL from June 2014 to June 2016 were retrospectively analyzed of Department of Spine Surgery, Changzheng Hospital, Naval Military Medical University. There were 31 males and 23 females, aging (68.4±4.3) years (rang: 46 to 82 years). All patients had a history of cervical spine trauma, confirmed by imaging examination of OPLL, and there are signs and symptoms related to cervical spinal cord compression. Eighteen patients underwent one-stage laminoplasty combine with short-segment pedicle screw fixation(group A), and 15 patients underwent posterior cervical laminectomy and pedicle screw fixation (group B). Twenty-one patients underwent posterior laminoplasty (C group). According to the range of OPLL and the compression of the spinal cord, the range of laminoplasty was selected. MRI scan was used to evaluated the compression condition of cervical spine and the injury condition of anterior longitudinal ligament injury and other factors that can cause local instability of the cervical spine. Posterior unilateral pedicle screw fixation (two pedicles) were performed in the instability segment. The neurological function of the patients was assessed by the Japanese Orthopedic Association (JOA) Score before surgery, the second day after surgery, 3 months, 1 year and the last follow-up. The cervical spine X-ray films were used to evaluate cervical curvature, cervical spine activity and internal fixation-related complications.@*Results@#The average follow-up time was 18 months (6-30 months). Satisfactory neurological improvement was achieved in all three groups, and no internal fixation-related complications occurred during follow-up. The range of laminoplasty was 22 cases in 4 segments (C3-C6, C4-C7) and 17 cases in 5 segments (C3-C7). Unilateral pedicle screw fixation was performed in 11 patients with C3-4 fixation and 7 patients with C4-5 fixation. Cervical curvature was basically the same in the three groups after operation and at the last follow-up. No significant changes in cervical curvature and kyphosis were observed during the follow-up period. The overall cervical mobility (C2-C7) in group A and group C had no significant difference compared with preoperative (P=0.077). The overall mobility of cervical vertebrae in group B was significantly lower than that before surgery (P=0.013).@*Conclusions@#For cervical spine trauma patients with OPLL, laminoplasty combined short-segment pedicle screw fixation can increase cervical segmental stability while extensive decompression of cervical spinal cord compression. At the same time, to some extent, the complications of postoperative axial symptoms caused by posterior cervical laminectomy and pedicle screw fixation were avoided.

Stem cell models for commercialization / 中国组织工程研究

BACKGROUND: Stem cells are the potentially immortal cells capable of self-renewal, which are essential to the mystery of human development and aging, and are also the core of research for regenerative medicine. OBJECTIVE: To summarize the biological characteristics of embryonic stem cells, adult stem cells and induced pluripotent stem cells, to review the clinical and commercial applications in stem cell therapy and drug screening, and to analyze the problems and prospects in stem cell industry. METHODS: We searched relevant articles about stem cell models in PubMed and CNKI databases during 1995 to 2017 on internet, and took"stem cells, embryonic stem cells, adult stem cells, induced pluripotent stem cells, stem cell therapy, drug screening" as the keywords in English and Chinese, respectively. RESULTS AND CONCLUSION: According to the origin, stem cell models are divided into three types: embryonic stem cells, adult stem cells and induced pluripotent stem cells. Different types of stem cells have their unique biological advantages. Embryonic stem cells can generate all somatic cell types, but the application is limited by ethical disputes. As for adult stem cells, there are the most extensive and in-depth, studies as the well as the most prevalent and mature applications. Induced pluripotent stem cells have similar characteristics as embryonic stem cells, and furthermore their use avoids source restriction, moral and ethical controversies, bringing new opportunities for stem cell application. Stem cell-based cell therapy has shown successful achievement. There have been a few commercial products about adult stem cells-based cell therapy; in the meanwhile both embryonic stem cells and induced pluripotent stem cells are making their way into clinical trials. In addition, pluripotent stem cells hold great promise for the specific drug screening because they enable scientists to establish a variety of cell and disease models in vitro.
