Objective:To investigate the expression of Toll-like receptor 4(TLR4)and extracellular signal-regulated protein kinase 1/2(ERK1/2)in decidua tissue of patients with unexplained spontaneous abortion and their correlation.Methods:The expres-sions of TLR4,ERK1/2 and p-ERK1/2 in decidua tissues of 32 patients with unexplained spontaneous abortion(abortion group)and 32 normal pregnancy(control group)were detected by immunohistochemistry and Western blot,respectively.The correlation between TLR4 and p-ERK1/2 in abortion group were analyzed by Pearson hierarchical correlation analysis.Results:In immunohistochemical experiments,the cytoplasm of decidua cells in the two groups is the expression locus of TLR4,ERK1/2 and p-ERK1/2,the expression of the three proteins were different,and the expressions of TLR4 and p-ERK1/2 in abortion group were significantly higher than that in control group(P<0.01).There was no significant difference in ERK1/2 expression between abortion group and control group(P>0.05);In decidua tissue samples of abortion group,the protein level of TLR4 was higher than that of control group(P<0.05);the pro-tein level of p-ERK1/2 was significantly higher than that of control group(P<0.01),and the protein level of ERK1/2 in decidua tissue of abortion group was not statistically different from that of control group(P>0.05).TLR4 was positively correlated with p-ERK1/2 expression in abortion group(r=0.890,P<0.01).Conclusion:Abnormal activation of TLR4/ERK1/2 signaling pathway may be one of the mechanisms of unexplained spontaneous abortion.

Component analysis and network pharmacology of flavonoids in Sophora flavescens tissues at anthesis / 药学学报

italic>Sophora flavescens is a traditional Chinese medicine rich in flavonoids and has wide application potential in drug development and clinical practice. In this study, a total of 227 flavonoids were detected among five tissues of S. flavescens during anthesis using widely targeted metabolomics techniques. There were 137 flavonoids shared by five S. flavescens tissues and 18 root-specific flavonoids. There were 156, 155, 156 and 150 differentially accumulated metabolites identified in stem, leaf, flower, and young pod, respectively, compared with root. Forty-seven potentially active flavonoid components in S. flavescens were identified using the PubChem and SwissADME databases. The 58 potential target proteins for these potentially active components were predicted to be important in the treatment of type 2 diabetes mellitus (T2DM) based on the SwissTargetPrediction and GeneCards database. These 58 target proteins were used to construct a protein-protein interaction network through the STRING database, from which we performed GO and KEGG functional enrichment analysis. The mechanisms by which S. flavescens flavonoids may be useful in the treatment of T2DM was further explored in a multi-level and systematic way based on a "component-target-pathway" network. Finally, ten key potentially effective components were identified and found to be mainly distributed in the roots, flowers, and pods, and their content varied significantly between tissues. The results predict that the key targets of S. flavescens flavonoids in the treatment of T2DM are AKT1, ESR1, EGFR, PIK3R1, TNF and PTGS2, and that they play a hypoglycemic role through the regulation of endocrine resistance, AGE-RAGE, the PI3K-Akt signaling pathway, EGFR tyrosine kinase inhibitor resistance and other signaling pathways. This analysis of the tissue distribution and network pharmacology of S. flavescens flavonoids provides a theoretical basis for further studies on S. flavescens metabolites, the rational development and utilization of the S. flavescens aboveground parts, and initiates a comprehensive exploration of the mechanisms by which S. flavescens can be used in the treatment of T2DM.

Clinical features of autoimmune encephalitis secondary to epidemic encephalitis B in 5 children / 中国当代儿科杂志

OBJECTIVES@#To study the clinical features of children with autoimmune encephalitis (AE) secondary to epidemic encephalitis B (EEB).@*METHODS@#A retrospective analysis was performed on the medical data of five children with EEB with "bipolar course" who were treated in Children's Hospital Affiliated to Zhengzhou University from January 2020 to June 2022.@*RESULTS@#Among the five children, there were three boys and two girls, with a median age of onset of 7 years (range 3 years 9 months to 12 years) and a median time of 32 (range 25-37) days from the onset of EEB to the appearance of AE symptoms. The main symptoms in the AE stage included dyskinesia (5/5), low-grade fever (4/5), mental and behavioral disorders (4/5), convulsion (2/5), severe disturbance of consciousness (2/5), and limb weakness (1/5). Compared with the results of cranial MRI in the acute phase of EEB, the lesions were enlarged in 3 children and unchanged in 2 children showed on cranial MRI in the AE stage. In the AE stage, four children were positive for anti-N-methyl-D-aspartate receptor antibody (one was also positive for anti-γ-aminobutyric acid type B receptor antibody), and one was negative for all AE antibodies. All five children in the AE stage responded to immunotherapy and were followed up for 3 months, among whom one almost recovered and four still had neurological dysfunction.@*CONCLUSIONS@#EEB can induce AE, with anti-N-methyl-D-aspartate receptor encephalitis as the most common disease. The symptoms in the AE stage are similar to those of classical anti-N-methyl-D-aspartate receptor encephalitis. Immunotherapy is effective for children with AE secondary to EEB, and the prognosis might be related to neurological dysfunction in the acute phase of EEB.

Effect of Cyr61 on Imatinib Resistance in Chronic Myeloid Leukemia and Its Mechanism / 中国实验血液学杂志

OBJECTIVE@#To investigate the effect of Cyr61 on imatinib (IM) resistance in chronic myeloid leukemia (CML) and its mechanism.@*METHODS@#Cyr61 level in cell culture supernatant was determined by enzyme-linked immunosorbent assay. The expression of Cyr61 and Bcl-xL were measured by real-time PCR and Western blot. Cell apoptosis was analyzed using an Annexin V-APC Kit. Expression of signal pathways related proteins was determined by Western blot.@*RESULTS@#The level of Cyr61 obviously increased in K562G cells (IM resistance to CML cell line K562). Down-regulating the expression of Cyr61 decreased the resistance of K562G cells to IM and promoted IM induced apoptosis. In CML mouse model, down-regulating the expression of Cyr61 could increase the sensitivity of K562G cells to IM. The mechanism studies showed that Cyr61 mediated IM resistance in CML cells was related to the regulation of ERK1/2 pathways and apoptosis related molecule Bcl-xL by Cyr61.@*CONCLUSION@#Cyr61 plays an important role in promoting IM resistance of CML cells. Targeting Cyr61 or its related effectors pathways may be one of the ways to overcome IM resistance of CML cells.

Comparison of the predictive value of the modified CADILLAC, GRACE and TIMI risk scores for the risk of short-term death in patients with acute ST segment elevation myocardial infarction after percutaneous coronary intervention / 中华危重病急救医学

Objective:To establish a modified controlled abciximab and device investigation to lower late angioplasty complication (CADILLAC) score, and to compare the predictive value of modified CADILLAC score, the global registry of acute coronary event (GRACE) score and the thrombolysis in myocardial infarction (TIMI) score in predicting the risk of short-term death after percutaneous coronary intervention (PCI) in patients with acute ST segment elevation myocardial infarction (STEMI).Methods:A retrospective study was conducted. The clinical data of 169 STEMI patients under going PCI admitted to the department of cardiology of Guizhou Provincial People's Hospital from September 2019 to December 2020 through emergency chest pain fast track were enrolled. A multivariate Logistic regression analysis was used to screen the factors closely related to the mortality risk within 30 days of STEMI, and a modified CADILLAC scoring system was established by referring to CADILLAC scoring settings. The score of modified CADILLAC, GRACE and TIMI scores of patients were calculated after admission, and the number of deaths due to cardiovascular disease (CVD) within 30 days after onset was recorded. The receiver operating characteristic curve (ROC curve) was used to evaluate the predictive value of three scoring systems on the risk of death within 30 days after PCI in patients with STEMI.Results:In 169 STEMI patients, 16 patients died of CVD within 30 days after PCI, and the actual case mortality was 9.47%. Multivariate Logistic regression analysis showed that age > 75 years old, cardiac function Killip ≥ Grade Ⅲ, ventricular arrhythmia, ST segment elevation ≥ 0.2 mV, cardiac troponin I (cTnI) increase, systolic blood pressure (SBP) < 90 mmHg (1 mmHg ≈ 0.133 kPa) were all independent predictors of death after PCI in STEMI patients. The improved CADILLAC scoring system was constructed based on the above predictive factors combined with left ventricular ejection fraction (LVEF) less than 0.40. The GRACE, TIMI and modified CADILLAC scores of dead patients were significantly higher than those of survival patients (GRACE score: 197.60±31.83 vs. 149.81±36.72, TIMI score: 11.21±2.13 vs. 7.27±1.97, modified CADILLAC score: 12.60±2.52 vs. 6.96±2.17, all P < 0.05). The higher the risk stratification of the three scores, the higher the mortality of patients with CVD within 30 days after PCI [the mortality of patients with low, medium and high risk in GRACE score were 2.41% (2/83), 9.61% (5/52) and 26.47% (9/34); the mortality of patients with low, medium and high risk in TIMI score were 3.12% (3/96), 12.82% (5/39) and 23.53% (8/34); and the mortality of patients with low, medium and high risk in modified CADILLAC score were 3.19% (3/94), 7.69% (4/52) and 39.13% (9/23), respectively, all P < 0.01]. The area under the ROC curve (AUC) of the GRACE, TIMI and the modified CADILLAC scores predicting the risk of death 30 days after PCI in STEMI patients were 0.855 [95% confidence interval (95% CI) was 0.702-0.923], 0.725 (95% CI was 0.666-0.812) and 0.882 (95% CI was 0.732-0.936), respectively, all P = 0.000; the sensitivity of its prediction accuracy were 81.59%, 78.65% and 89.26%, and the specificity were 78.62%, 57.12% and 75.54%, respectively. Conclusions:The GRACE and the modified CADILLAC scores have predictive value for the short-term mortality risk of STEMI patients after PCI, and the modified CADILLAC score is more accurate. But the TIMI score has a poor predictive effect on the short-term mortality risk of STEMI patients after PCI.

Influences of the copy number of SMN2 and transcript level of fl-SMN2 on the phenotype and survival of spinal muscular atrophy / 中华实用儿科临床杂志

Objective:To explore the distribution of the copy number of survival motor neuron gene 2 ( SMN2) and the transcript level of the full-length SMN2 ( fl-SMN2) transcript level in patients with type 1-3 spinal muscular atrophy (SMA), and to evaluate their influences on disease severity, progression, and prognosis. Methods:It was a retrospective study involving 78 therapy-naive SMA patients with SMN1 gene homozygous deletion who were diagnosed and treated in the Capital Institute of Pediatrics from January 2019 to December 2021.Cross-sectional clinical data, including age at onset, motor milestones, and complications were recorded.They were followed up for monitoring motor function degeneration and survival.The copy number of SMN2 and the transcript level of fl-SMN2 were detected.Differences between groups were compared by the Student′s t-test or One- Way ANOVA or Chi- square test.Kaplan-Meier analysis was used for survival analysis, and Kendall′ s tau- c was performed to assess the correlation of these two biomarkers with SMA phenotypes, age at onset, motor milestones, and survival. Results:Of the 78 SMA patients, there were 17 cases (21.8%) of type 1, 34 cases(43.6%) of type 2, and 27 cases(34.6%) of type 3.Seven cases(41.2%) type 1 SMA patients died, with a median survival time of 11 months, and no deaths were observed in type 2 and type 3 SMA patients.There was a significant difference in the median age at onset among SMA patients with 2, 3, and 4 copies of SMN2 (1.8, 12.0, and 24.0 months, respectively; F=4.943, P=0.01). The mean transcript level of fl-SMN2 in type 1, 2 and 3 SMA patients were 196.25±68.79, 331.21±108.79 and 455.69±122.27, respectively ( F=37.154, P<0.001). The survival rate of SMA with 2 SMN2 copies at 1, 2, and 5 years were 50.5%, 0, and 0, respectively, and their median survival age was 7 months.The survival rate of SMA with 3 and 4 SMN2 copies at 5 years were 97.4% and 100.0%, respectively.Moreover, a negative correlation was observed between the transcript level of fl-SMN2 and phenotype severity ( Kendall′ s tau- c=-0.444, P<0.001), and the transcript level of fl-SMN2 of the survival group was much higher than that of the death group (342.93±125.74 vs.212.14±92.31). More copies of SMN2 and higher transcript level of fl- SMN2 indicated more motor function acquisitions (head control, sitting and walking) ( P<0.001). In addition, there was a significant difference in the transcription level of fl-SMN2 between the undegenerated group and the degenerated group in sitting and standing ( F=5.432, P=0.023 and F=4.315, P=0.047, respectively). Conclusions:Both the copy number of SMN2 and the transcript level of fl-SMN2 are correlated with SMA severity, survival, and motor milestones, serving as valuable biomarkers for evaluating phenotypic severity of SMA.The transcript level of fl-SMN2 s may play an important role in the degeneration of sitting and standing.

Hypoxic pretreatment enhancing the angiogenesis of aged human bone marrow mesenchymal stem cells through hypoxia inducible factor-1α / 解剖学报

Objective To investigate the effect of hypoxic pretreatment on the angiogenesis of aged human bone marrow mesenchymal stem cells (hBMSCs), so to provide experimental support for more effective autologous stem cell transplantation therapy in aged patients with ischemic myocardial injury. Methods The aged hBMSCs were cultured in a hypoxic incubator, and then the cell morphology was observed under inverted phase-contrast microscope, the surface markers were detected by flow cytometry, and the differentiation potential was detected by osteogenic and adipogenic differentiation. Subsequently, the conditioned medium (CM) of young hBMSCs under normoxic culture (norCM), the conditioned media of aged hBMSCs under normoxic and hypoxic culture(hypoCM) were collected respectively. They were named as norCM-young, norCM-old and hypoCM-old. The equal volume of medium, which was not treated with stem cells, was set as control group. Human umbilical vein endothelial cells (HUVECs) were treated with 4 conditioned media, the cell survival rate was detected by CCK-8 assay, and the tube formation experiment was used to detect the angiogenesis ability in vitro. The BCA method was used to detect the total protein concentration of the conditioned medium of each group, and the Western blotting was used to detect the expression of hypoxia inducible factor-1α (HIF-1α) in the cells and the conditioned media. Results There was not significant effect of hypoxic pretreatment on the morphology, surface markers and differentiation ability of aged hBMSCs (P > 0. 05. n ≥ 3). Compared with the norCM-old group, hypoCM-old group significantly improved the survival of HUVECs under hypoxia-reoxygenation condition (P < 0. 05, n = 5), and the tube formation ability of it (P<0. 01, n = 5). The total protein concentration of hypoCM-old group was significantly higher than that of norCM-old group (P<0. 05, n = 3). The expression of HIF-1α in hBMSCs of hypo-old group was significantly higher than that of nor-old group (P<0. 05,n = 3), while the content of HIF-1α in conditioned medium of hypoCM-old group was significantly higher than that in norCM-old group (P<0. 01,n = 3). Conclusion The aged hBMSCs pretreated with hypoxia can promote the survival and tube formation of HUVECs through paracrine in vitro, which is HIF-1α-related.

Objective:To explore application status and development trend of spinal muscular atrophy (SMA) genetic diagnosis technology based on the national rare diseases registry system of China.Method:A total of 200 SMA children registered at the Capital Institute of Pediatrics from July 2016 to December 2018 were included in this retrospective cross-sectional survey. The basic data, clinical subtypes, genotypes, and related genetic testing information of SMA children were obtained by checking SMA registration information, genetic testing reports, and also by telephone follow-up. The patient number and the composition of different genetic diagnosis technologies were analyzed by the stratification of genetic testing at various time. The correlation between the proportion of genetic diagnosis technology and genetic testing time was analyzed with Pearson correlation analysis.Result:There were 3 SMA cases with incomplete data, the remaining 197 SMA cases were included in this study. There were 37 (18.8%), 115 (58.4%) and 45 (22.8%) patients with type Ⅰ, Ⅱ and Ⅲ SMA, respectively. There were 185 cases of SMN1 homozygous deletion (93.9%), and 12 cases with compound heterozygotes (6.1%). Seven SMA-related genetic technologies were used from 2004 to 2017. MLPA accounted for 54.1% (100/185) used approach, followed by PCR-RFLP and first-generation sequencing, which accounted for 22.7% (42/185) and 10.3% (19/185), respectively. Nine, 6, 5 and 4 cases were tested with AS-PCR, qPCR, WES and DHPLC, respectively (2.2%-4.9%). The proportion of MLPA increased gradually since 2010 ( r=0.95, P<0.05), while PCR-RFLP declined gradually since 2004 ( r=-0.99, P<0.05). No correlation was found between technology and testing time for other genetic testing technologies ( P>0.05). The proportion of quantitative genetic technologies (MLPA, qPCR and DHPLC) increased gradually since 2010 ( r=0.94, P<0.05), and qualitative genetic technologies (PCR-RFLP, first-generation sequencing, AS-PCR and WES) decreased gradually since 2004 ( r=-0.94, P<0.05). The duplication detection rates of homozygous deletion and compound heterozygous mutation were 12.4% (23/185) and 41.7% (5/12), respectively (χ 2=5.86, P<0.05). During 2008-2015, the proportion of "the reports of both copy numbers of SMN1 gene and SMN2 gene" increased from 56.8% (21/37) in 2008-2015 to 69.1% (56/81) in 2016-2017. Conclusion:Genetic diagnosis of SMA has gradually developed from qualitative detection technology to quantitative detection technology, such as MLPA and qPCR, in China. In more and more SMA quantitative test reports, quantitative results of SMN2 gene are also provided in addition to quantitative results of SMN1 gene.

DNA barcoding identification of original plants of a rare medicinal material Resina Draconis and related Dracaena species / 中国中药杂志

Resina Draconis, a rare and precious traditional medicine in China, is known as the "holy medicine for promoting blood circulation". According to the national drug standard, it's derived from the resin extracted from the wood of Dracaena cochinchinensis, a Liliaceae plant. In addition, a variety of Dracaena species all over the world can form red resins, and there is currently no molecular identification method that can efficiently identify the origin of Dracaena medicinal materials. In this study, seven species of Dracaena distributed in China were selected as the research objects. Four commonly used DNA barcodes(ITS2, matK, rbcL and psbA-trnH), and four highly variable regions(trnP-psaJ, psbK-psbI, trnT-trnL, clpP) in chloroplast genome were used to evaluate the identification efficiency of Dracaena species. The results showed that clpP sequence fragment could accurately identify seven species of Dracaena plants. However, due to the long sequence of clpP fragment, there were potential problems in the practical application process. We found that the combined fragment "psbK-psbI+ trnP-psaJ" can also be used for accurate molecular identification of the Resina Draconis origin plants and relative species of Dracaena, which were both relatively short sequences in the combined fragment, showing high success rates of amplification and sequencing. Therefore, the "psbK-psbI+ trnP-psaJ" combined fragment can be used as the DNA barcode fragments for molecular identification of Resina Dracon's origin plants and relative species of Dracaena. Research on the identification of Dracaena species, the results of this study can be used to accurately identify the original material of Resina Draconis, and providing effective means for identification, rational development and application of Resina Draconis base source.

Effect of breastfeeding on the development of infection-related diseases during hospitalization in late preterm infants in 25 hospitals in Beijing, China / 中国当代儿科杂志

OBJECTIVE@#To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases.@*METHODS@#Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases.@*RESULTS@#A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, @*CONCLUSIONS@#Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

Psychological care combined with enhanced recovery after surgery management in perioperative nursing care of andrological patients: A randomized controlled study / 中华男科学杂志

Objective@#To evaluate the validity of psychological care combined with enhanced recovery after surgery (PC+ERAS) management in perioperative nursing care of andrological patients.@*METHODS@#A total of 300 male patients undergoing andrological surgery were included in this study, 150 given PC+ERAS and the other 150 receiving routine nursing care as controls. We evaluated anxiety and depression of all the patients on admission and discharge using Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS), and compared post-operative hospital days, off-bed time, first passage of flatus, Visual Analog Scale (VAS) score and satisfaction with nursing care between the two groups of patients.@*RESULTS@#On discharge, significant improvement was observed in SAS and SDS scores in the PC+ERAS group compared with the baseline, even more significant than in the control group (P 0.05). The patients in the PC+ERAS group also achieved a significantly shorter post-operative hospital stay, earlier post-operative off-bed time and passage of flatus, lower VAS score, and higher satisfaction with nursing care than those in the control group (P < 0.05).@*CONCLUSIONS@#Psychological care combined with ERAS management deserves wide application in the perioperative nursing care of andrological patients, which can significantly improve the patients' anxiety and depression, shorten post-operative hospital stay, reduce VAS score, and increase their satisfaction with nursing care.

Professor 's academic thoughts and acupoint selection experience for hot flashes / 中国针灸

Professor is a well-known national veteran doctor with over 70 years of clinical experience. He has unique academic thoughts and clinical experience for common diseases and some difficult and complicated diseases. This paper mainly introduces professor 's syndrome-differentiation thought and experience of acupoint selection for hot flashes. It is emphasized that common hot flashes, such as hot flashes and night sweats, are different between and . While regulating and , more attention should be paid to - harmony, which is not only suitable for women's perimenopausal syndrome, but also for a series of clinical diseases caused by refractory drugs such as endocrine therapy after breast cancer surgery. At the same time of acupoint selection based on syndrome differentiation, a more rational prescriptions should be made according to the duration of the disease and the experience acupoints to improve the clinical efficacy.
