Reverse effect of Semaphorin-3F on rituximab resistance in diffuse large B-cell lymphoma via the Hippo pathway / 中华医学杂志(英文版)

BACKGROUND@#Exploring the underlying mechanism of rituximab resistance is critical to improve the outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Here, we tried to identify the effects of the axon guidance factor semaphorin-3F (SEMA3F) on rituximab resistance as well as its therapeutic value in DLBCL.@*METHODS@#The effects of SEMA3F on the treatment response to rituximab were investigated by gain- or loss-of-function experiments. The role of the Hippo pathway in SEMA3F-mediated activity was explored. A xenograft mouse model generated by SEMA3F knockdown in cells was used to evaluate rituximab sensitivity and combined therapeutic effects. The prognostic value of SEMA3F and TAZ (WW domain-containing transcription regulator protein 1) was examined in the Gene Expression Omnibus (GEO) database and human DLBCL specimens.@*RESULTS@#We found that loss of SEMA3F was related to a poor prognosis in patients who received rituximab-based immunochemotherapy instead of chemotherapy regimen. Knockdown of SEMA3F significantly repressed the expression of CD20 and reduced the proapoptotic activity and complement-dependent cytotoxicity (CDC) activity induced by rituximab. We further demonstrated that the Hippo pathway was involved in the SEMA3F-mediated regulation of CD20. Knockdown of SEMA3F expression induced the nuclear accumulation of TAZ and inhibited CD20 transcriptional levels via direct binding of the transcription factor TEAD2 and the CD20 promoter. Moreover, in patients with DLBCL, SEMA3F expression was negatively correlated with TAZ, and patients with SEMA3F low TAZ high had a limited benefit from a rituximab-based strategy. Specifically, treatment of DLBCL cells with rituximab and a YAP/TAZ inhibitor showed promising therapeutic effects in vitro and in vivo .@*CONCLUSION@#Our study thus defined a previously unknown mechanism of SEMA3F-mediated rituximab resistance through TAZ activation in DLBCL and identified potential therapeutic targets in patients.

@#Objective     To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods     Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results     Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion     The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.

Objective:To investigate the relationship between serum vascular endothelial growth factor (VEGF) levels and white matter high signal and non-dementia vascular cognitive dysfunction in patients with cerebral small vascular disease (CSVD).Methods:Total 106 patients with CSVD who were admitted to the Department of Neurology of the First Affiliated Hospital of Xinxiang Medical College from April 2019 to December 2020 were enrolled.They were divided into vascular cognitive impairment no dementia group (VCIND group, n=47) and no vascular cognitive impairment group (N-VCI group, n=59)according to mini-mental assessment scale (MMSE), Montreal cognitive assessment (MoCA) scale and activity of daily living scale (ADL). Serum VEGF levels were detected by enzyme-linked immunosorbent assay (ELISA). The baseline data, serum VEGF levels, MoCA score and Fazekas score were compared between the two groups.The correlation between serum VEGF level and white matter high signal and cognitive function was analyzed.SPSS 19.0 software was used for data processing.The statistical methods were t-test, Chi square test, nonparametric test, Logistic regression analysis, Pearson correlation analysis and Spearman correlation analysis. Results:There were significant differences in serum VEGF level((464.18±114.58)pg/mL, (414.17±45.80)pg/mL, F=22.880), MoCA score((13.07±6.48), (20.17±4.06), F=17.920) and Fazekas score (4(3, 5), 3(1, 3), Z=-4.189)between the two groups (all P<0.05). The level of VEGF( β=0.008, OR=1.008, 95% CI=1.001-1.015, P<0.05) was the influencing factor of cognitive function in patients with CSVD .The level of VEGF was negatively correlated with the total score of MoCA, attention and calculation power, and orientation ability ( r=-0.345, -0.373, -0.445, all P<0.05) and it was positively correlated with the total Fazekas score and the Fazekas score of paraventricular and deep white matter ( r=0.392, 0.495, 0.302, all P<0.05). There was a linear trend between the high signal grade of paraventricular and deep white matter and VCIND (both P<0.05). Conclusion:Serum VEGF level is correlated with cognitive function and white matter hyperintensity in patients with CSVD.The increase of VEGF level may be a factor reflecting cognitive dysfunction.In addition, with the increase of white matter hyperintensity level, the risk of VCIND in CSVD is increased.

Crescent sign for predicting the invasiveness of lung adenocarcinoma with pure ground-glass opacity / 中华放射学杂志

Objective:To evaluate the value of the crescent sign for predicting the invasiveness of lung adenocarcinoma presenting as pure ground-glass nodule (pGGN).Methods:The clinical, pathological and imaging data of 316 patients (320 pGGNs) confirmed lung adenocarcinoma by surgery and pathology from July 2013 to June 2018 in the First Affiliated Hospital of Wenzhou Medical University were retrospectively analyzed. All pGGNs were divided into preinvasive group (148 pGGNs) and invasive group (172 pGGNs) according to histopathology. Logistic regression analysis was used to determine the risk factors for invasiveness of pGGN, and the ROC curve analysis was performed on each risk factor.Results:Crescent sign was found in 24 cases (16.2%) in the preinvasive group and 49 (28.5%) in the invasive group, and the difference between the two groups was statistically significant (χ2=6.804 ,P=0.009).There were statistically significant differences in patient′s age, lesion size, shape, lobulation sign, and vascular stretch sign between the two groups ( P<0.05). The ROC curve showed that with the lesion size 10.5 mm as the optimal cut off value, the sensitivity for differential diagnosis of preinvasive and invasive lesions was 65.7%, the specificity was 61.5%, and the area under the curve was 0.666. Logistic regression analysis showed that maximum diameter of the lesion ≥10.5 mm, irregular shape, crescent sign and vascular stretch were independent risk factors of invasiveness of pGGN, and the OR value (95%CI) were 3.192 (1.981-5.144), 3.672 (1.545-8.725), 1.972 (1.104-3.521), and 2.026 (1.087-3.777), respectively. A logistic model was established based on the above four independent risk factors, and the area under curve was 0.711 (95%CI 0.655-0.768). Conclusion:Crescent sign can effectively reflect the invasiveness of pGGN. Maximum diameter of the lesion ≥10.5 mm, irregular shape, crescent sign and vascular stretch sign are independent risk factors of invasiveness of pGGN.

MiR-148a-3p Regulates the Invasion and Odontoblastic Differentiation of Human Dental Pulp Stem Cells via the Wnt1/β-Catenin Pathway

Background and Objectives@#MiR-148a-3p has been reported to regulate the differentiation of marrow stromal cell osteoblast. In this study, whether miR-148a-3p regulated the odontoblastic differentiation of human dental pulp stem cells (hDPSCs) or not was explored. @*Methods@#and Results: The hDPSCs were isolated and identified via flow cytometry. Targets of miR-148a-3p were identi-fied via bioinformatics and dual-luciferase reporter assay. After the cell was cultured in the odontogenic differentiation medium or infected, cell viability, invasion, and odontoblastic differentiation were detected via MTT, transwell, and Alizarin Red S staining, respectively. The miR-148a-3p, Wnt1, β-catenin, DSPP, DMP-1, RUNX2, OCN, and Smad4 expressions were determined by RT-qPCR and Western blot. The hDPSCs odontoblastic differentiation downregulated the miR-148a-3p expression and upregulated Wnt1 expression. Wnt1 was determined as the target for miR-148a-3p. MiR-148a-3p mimic and siWnt1 suppressed the cell viability, invasion, and odontoblastic differentiation of hDPSCs and inhibited the Wnt1, β-catenin, DSPP, DMP-1, RUNX2, OCN, and Smad4 expressions. In contrast, miR-148a-3p inhibitor and overexpressed Wnt1 promoted the cell viability, invasion, and odontoblastic differentiation of hDPSCs, and upregulated the Wnt1, β-catenin, DSPP, DMP-1, RUNX2, OCN, and Smad4 expressions. Also, miR-148a-3p mimic and inhibitor reversed the effects of Wnt1 overexpression and siWnt1. @*Conclusions@#MiR-148a-3p modulated the invasion and odontoblastic differentiation of hDPSCs through the Wnt1/β-catenin pathway.

Objective:To investigate the effects of curdione on the proliferation， apoptosis and cell cycle of triple negative breast cancer cell line MDA-MB-231. Method:MDA-MB-231 cells were cultured<italic> in vitro</italic> with capecitabine （positive control） and curdione at different concentrations （125， 250， 500， 1 000， and 2 000 μmol·L^-1）， respectively， for detecting their viability using the cell counting kit-8 （CCK-8） at 24 and 48 h. Three effective inhibitory concentrations （250， 500， and 1 000 μmol·L^-1） against cell proliferation were selected for subsequent experiments. The effect of curdione on cell cycle was determined by flow cytometry combined with propidium iodide （PI） staining. After the set-up of high-concentration （2 000 μmol·L^-1） group， the effect of curdione on cell mitochondrial membrane potential was measured by JC-1（5，5，6，6-tetrachloro-1，1，3，3-tetraethylbenzimidazolylcarbocyanine iodide） staining， followed by the detection of cell apoptosis by flow cytometry combined with Annexin V-FITC/PI double staining. The changes in cell cycle status and apoptosis-related protein expression following curdione intervention were assayed by Western blot. Result:Compared with the blank control， curdione at 250， 500， 1 000， and 2 000 μmol·L^-1significantly inhibited the proliferation of MDA-MB-231 cells （<italic>P</italic><0.01）， exhibiting a concentration- and time-response relationship. The half maximal inhibitory concentration （IC₅₀） values at 24 and 48 h were 1 607 and 1 401 μmol·L^-1， respectively. Curdione at 250， 500， and 1 000 μmol·L^-1 arrested cells in G₁ phase. Curdione at 250 μmol·L^-1had no effect on cell mitochondrial membrane potential， which， however， declined significantly in the 500， 1 000， and 2 000 μmol·L^-1groups （<italic>P</italic><0.05， <italic>P</italic><0.01）. Curdione at 250， 500， and 1 000 μmol·L^-1obviously increased the proportion of apoptotic cells （<italic>P</italic><0.05， <italic>P</italic><0.01）. Curdione at each concentration elevated the Bcl-2-associated X protein （Bax）/B-cell lymphoma 2 （Bcl-2） ratio （<italic>P</italic><0.05， <italic>P</italic><0.01）， but did not change the cysteinyl aspartate-specific protease-3 （Caspase-3） expression. The protein expression levels of Caspase-9， cleaved Caspase-9， cleaved Caspase-3， p53， and p21 were up-regulated （<italic>P</italic><0.05）. Conclusion:A certain concentration of curdione inhibits the proliferation of MDA-MB-231 cells， which may be related to its efficacy in arresting cell cycle and inducing apoptosis.

Cornelia de Lange syndrome (CdLS) is a genetic syndrome with severe neurodevelopmental disorders as the main manifestation. Its clinical manifestations included mental retardation, typical facial features, intrauterine and postnatal developmental delay, and deformity in multiple organs and systems, with an incidence rate of about 1/10000 to 1/30000. International CdLS Consensus Group was established in 2017 and issued the first international consensus on CdLS, i.e., "Diagnosis and management of Cornelia de Lange syndrome: first international consensus statement", in July 2018. Being developed through a modified Delphi consensus process, this consensus provides guidance on the diagnosis and management of children with CdLS. This article gives an interpretation of this consensus, aiming to help clinicians with early identification, diagnosis, standard follow-up, and management of this disease.

Clinical Characteristics and Bone Marrow Histopathology Features in Essential Thrombocythaemia Patients with Different Gene Mutation in China / 中国实验血液学杂志

OBJECTIVE@#To investigate the clinical characteristics, laboratorial and bone marrow pathological features of primary thrombocytopenia (ET) patients with different mutations of CALR, JAK2 and MPL genes.@*METHODS@#The chinical data of 120 cases of ET in Jiangsu provincial people's hospital/ The First Affiliated Hospital of Nanjing Medical University from January 2015 to December 2017 were collected and analyzed, including 76 cases with JAK2 gene mutation, 40 cases with CALR gene mutation, 2 cases with MPL gene mutations, 2 cases without gene mutation.@*RESULTS@#Among the ET patients, compared with the JAK2 gene mutation, CALR gene mutation showed statistically significant deareament of white blood cells and hemoglobin (P=0.001, P=0.01) and the male platelets in CALR group showed significant increament (P=0.04). Fourthermore, the average number of megakaryocytes and its cluster numbers in each hight power field of vision showed statistically significant decreament in CALR group as compared with JAK2 group (P=0.001, P=0.001), and thrombotic events in CALR group were signicantly lower than those in JAK2 group (7.5% vs 18.4%) (P=0.03).@*CONCLUSION@#Mutations of CALR, JAK2 have different clinical characteristics and blood pathological changes of Chinese ET patients, and their clinical significance is worth to explore.

Joint effect of school and family on domestic second-hand smoke exposure in middle school students / 中国学校卫生

Objective@#To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents.@*Methods@#A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected.@*Results@#The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08).@*Conclusion@#The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.

Premature infant born to a convalescent mother with COVID-19 in mid-term pregnancy / 中华围产医学杂志

We report a female infant born preterm to a woman at 35 gestational weeks and four days in a normal pregnancy prior to delivery, with normal liquor volume and good maternal and infant outcomes. The baby was transferred to the neonatal department 30 min after birth at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, on March 21, 2020. The infant weighed 2 800 g with 7 and 9 Apgar scores respectively at 1 and 5 min. The mother had been diagnosed with COVID-19 at 26 +6 weeks of pregnancy and the maternal serum level of IgM was negative and that of IgG was 20.77 AU/ml (normal reference <10 AU/ml) before delivery. The baby had hypoglycemia on admission, and the blood sugar stabilized after treatment. Though early mild feeding intolerance occurred, the baby was able to feed normal by eight days after birth. The baby was in good condition during hospitalization and discharged. Throat swab specimens obtained from the infant on the 2nd, 3rd and 8th day after birth for SARS-Cov-2 RNA detection were all negative. On the 2nd and 8th day after birth, SARS-Cov-2 IgM in the neonatal serum were negative, while elevated IgG levels of 30.2 AU/ml and 25.3 AU/ml (normal reference value <10 AU/ml) were observed, suggesting that the infant's IgG antibody of SARS-CoV-2 may have come from the mother. According to this case report, no intrauterine vertical transmission was found in the pregnancy with SARS-CoV-2 infection in the second trimester, while further follow-up is still needed.

Analysis of malaria epidemic situation before and after malaria elimination in Qiandongnan Prefecture of Guizhou / 中华地方病学杂志

Objective:To analyze the characteristics of malaria epidemic situation before and after malaria elimination in Qiandongnan Prefecture, and to provide the basis for establishment of effective strategies and measures to consolidate the achievements of malaria prevention and control.Methods:The data of malaria cases in 16 counties (cities) of Qiandongnan Prefecture from 2005 to 2018 were collected, and descriptive epidemiological method was used to analyze the infection rate of Plasmodium among local residents and floating population before (2005-2011) and after (2012-2018) elimination of malaria, and the characteristics of population distribution, seasonal distribution, species of Plasmodium and types of malaria vectors were analyzed. Results:Before elimination of malaria, total of 1 412 cases of malaria were reported, among those cases, 1 361 cases were local cases, accounting for 96.39% of the total cases. After elimination of malaria, total of 17 cases were reported, all of them were imported cases. After comparison of malaria cases before and after the elimination, the proportion of people aged from 18 to 60 was 70.54% (996/1 412) before the elimination, all 17 imported cases were 18-60 years old after the elimination, and the proportion of children/students decreased from 24.65% (348/1 412) before the elimination to 0 after the elimination. The peak incidence of malaria cases before the elimination was from June to October, and cases occurred every month. After the elimination, the imported cases were sporadic. Plasmodium vivax was the main species of Plasmodium before the elimination (98.58%, 1 392/1 412), and Plasmodium falciparum was mainly imported after the elimination (70.59%, 12/17). Before and after the elimination, Anopheles sinensis, the malaria vector, was the dominant population, but no distribution of Anopheles minimus and Anopheles anthropophagus was found after 2015. Conclusions:After the elimination of malaria in Qiandongnan Prefecture, there is a risk of local malaria cases caused by imported cases. It is suggested that local authorities should focus on the treatment of suspected malaria cases and vector surveillance of overseas returnees in the future.
