OLIG2 expression level could be used as an independent prognostic factor for patients with cerebellar Glioblastoma (cGBM)

Abstract Objectives: The incidence of cerebellar Glioblastoma Multiforme (cGBM) is rare. Database like TCGA have not distinguish cGBM from GBM, our knowledge on cGBM gene expression characteristics is limited. The expression status of Oligodendrocyte Lineage Transcription factor 2 (OLIG2) and its clinical significance in cGBM is still unclear. Methods: The clinical data and tissue specimens of 73 cGBM patients were retrospectively studied. The association between OLIG2 expression level and the demographic characteristics of cGBM patients was identified by the Chi-Square test. The survival curves were drawn by Kaplan-Meier analysis. The independent prognostic factors was calculated according to Cox regression analysis. Results: The OLIG2 high expression was observed in about 57.5% (42/73) of the cGBM patients. Patients with high OLIG2 expression levels had a higher alive ratio at the end of follow-up (alive ratio: 70.6% vs. 29.4%, p = 0.04). The median survival time was 21 months and 13 months for high and low expression of OLIG2 (p < 0 .05). Univariate analysis and Multivariate analysis indicated that EOR (HR = 3.89, 95% CI 1.23−12.26, p = 0.02), low OLIG2 expression (HR = 5.26, 95% CI 1.13−24.59, p = 0.04), and without adjuvant therapy (HR = 4.95, 95% CI 1.22−20.00, p = 0.03) were independent risk factors for the OS of cGBM patients. Conclusion: High expression level of OLIG2 could be used as an independent favorable prognosis indicator in cGBM patients and be recognized as a characteristic biomarker of cGBM.

Analysis of 50 cases of bloodstream infection with Listeria monocytogenes / 中国热带医学

@#Abstract: Objective　To analyze the characteristics of bloodstream infection of Listeria monocytogenes and provide basis for the diagnosis and treatment of the disease. Methods　We retrospectively analyzed the cases of Listeria monomyrhosi bloodstream infection in Peking Union Medical College Hospital (PUMCH) from April 2012 to April 2022. The age, sex, onset time, underlying disease, symptoms, diagnosis, treatment and prognosis of the patients were analyzed, as well as the changes of white blood cells (WBC), neutrophils, lymphocytes, and C-reactive protein (CRP) before and after anti-infection treatment. Results　Fifty cases of Listeria monocytogenes bloodstream infection confirmed by blood culture were involved. The age of patients ranged from 0 to 82 (43.7±20.0) years old, among whom 20.0% were over 60 years old. The onset time of patients was the highest in spring (44.0%), followed by winter (24.0%), and relatively fewer in summer and autumn (14.0%-18.0%). The median diagnosis time was 3 days (1-60 days). After the etiological diagnosis, 45 patients (90.0%) had underlying diseases or pregnancy status, and 45 patients were adjusted to the target antibacterial treatment mainly with carbapenems (48.9%) and penicillins (44.4%). The level of WBC, neutrophils, lymphocytes, monocytes, and CRP after treatment were significantly lower than those pre-treatments (P<0.05). Among all patients, 36 cases (72.0%) were treated according to the Antimicrobial Treatment Guidelines for Fever Sanford, of which 26 cases (72.2%) were discharged from the hospital, two cases died, one case was transferred to other hospitals, and 7 cases had a poor prognosis. Conclusions　Autoimmune diseases, tumor diseases, pregnant patients are susceptible to Listeria monocytogenes infection. Penicillins are the first choice for effective empiric therapy. For the patients allergic to penicillins, trimethoprim/sulfamethoxazole or meropenem could be used.

Advances in diagnosis,prevention and treatment of flexible flatfoot in children / 中国学校卫生

Abstract@#Flexibleis an important classification of flat foot. Flatfoot occurs due to a variety of reasons and causes the medial longitudinal arch to collapse or disappear. However, many children still do not develop a normal foot arch as the grow, and a failure to intervene in a timely manner will greatly harm a child s normal mobility development. Timely detection and intervention are the key to improve the prognosis. There is a lack of uniform quantitative criteria for the diagnosis of flexible flatfoot. Currently, the commonly used diagnostic methods include physical examination, foot printing, plantar pressure test and imaging examination. This article reviews the risk factors, diagnosis, prevention and treatment of Flexible Flatfoot.

A novel nomogram can predict pathological T3a upstaged from clinical T1a in localized renal cell carcinoma

ABSTRACT Hypothesis: Nomogram can be built to predict the pathological T3a upstaging from clinical T1a in patients with localized renal cell carcinoma before surgery. Purpose: Renal cell carcinoma (RCC) patients with clinical T1a (cT1a) disease who are upstaged to pathological T3a (pT3a) have reduced survivals after partial nephrectomy. We aimed to develop a nomogram-based model predicting pT3a upstaging in RCC patients with preoperative cT1a based on multiple preoperative blood indexes and oncological characteristics. Materials and Methods: Between 2010 and 2019, 510 patients with cT1a RCC were individually matched according to pT3a upstaging and pathological T1a (pT1a) at a 1:4 ratio using clinicopathologic features. Least absolute shrinkage and selection operator regression analysis was used to identify the most important risk factor from 40 peripheral blood indicators, and a predictive model was established. Multivariate logistic regression analysis was performed with the screened blood parameters and clinical data to identify significant variables. Harrell's concordance index (C-index) was applied to evaluate the accuracy of the model for predicting pT3a upstaging in patients with cT1a RCC. Results: Out of 40 blood indexes, the top ranked predictor was fibrinogen (FIB). Age, the ratio of the tumor maximum and minimum diameter (ROD), FIB, and tumor size were all independent risk factors for pT3a upstaging in multivariate analysis. A predictive ARFS model (Age, ROD, FIB, tumor Size) was established, and the C-index was 0.756 (95% CI, 0.681-0.831) and 0.712 (95% CI, 0.638-0.785) in the training and validation cohorts, respectively. Conclusions: Older age, higher ROD, increased FIB level, and larger tumor size were independent risk factors for upstaging. The ARFS model has a high prediction efficiency for pT3a upstaging in patients with cT1a RCC.

Medical services for sports injuries and illnesses in the Beijing 2022 Olympic Winter Games / 世界急诊医学杂志（英文）

BACKGROUND: Beijing 2022 Olympic Winter Games was the second Games held amid the COVID-19 pandemic. To a certain extent, it has altered the way sporting activities operate. There is a lack of knowledge on injury risk and illness occurrence in elite winter sport athletes amid the COVID-19 pandemic. This study aimed to describe the incidence of injuries and illnesses sustained during the XXIV Olympic Winter Games in Beijing from February 4 to 20, 2022. METHODS: We recorded the daily number of injuries and illnesses among athletes reported by Beijing 2022 medical staff in the polyclinic, medical venues, and ambulance. We calculated injury and illness incidence as the number of injuries or illnesses occurring during competition or training, respectively, with incidence presented as injuries/illnesses per 100 athlete-days. RESULTS: In total, 2,897 athletes from 91 nations experienced injury or illness. Beijing 2022 medical staff reported 326 injuries and 80 illnesses, equaling 11.3 injuries and 2.8 illnesses per 100 athletes over the 17-day period. Altogether, 11％ of the athletes incurred at least one injury and nearly 3％ incurred at least one illness. The number of injured athletes was highest in the skating sports (n=104), followed by alpine skiing (n=53), ice track (n=37), freestyle skiing (n=36), and ice hockey (n=35), and was the lowest in the Nordic skiing disciplines (n=20). Of the 326 injuries, 14 (4.3％) led to an estimated absence from training or competition of more than 1 week. A total of 52 injured athletes were transferred to hospitals for further care. The number of athletes with illness (n=80) was the highest for skating (n=33) and Nordic skiing (n=22). A total of 50 illnesses (62.5％) were admitted to the department of dentistry/ophthalmology/otolaryngology, and the most common cause of illness was other causes, including preexisting illness and medicine (n=52, 65％). CONCLUSION: Overall, 11％ of athletes incurred at least one injury during the Games, which is similar to the findings during the Olympic Winter Games in 2014 and 2018. Regarding illness, 2％ of athletes were affected, which is approximately one-third of the number affected in the 2018 Olympic Winter Games.

The Role of miR-34c-5p in Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells

Background and Objectives@#Osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) plays a critical role in the success of lumbar spinal fusion with autogenous bone graft. This study aims to explore the role and specific mechanism of miR-34c-5p in osteogenic differentiation of BMSCs. @*Methods@#and Results: Rabbit model of lumbar fusion was established by surgery. The osteogenic differentiation dataset of mesenchymal stem cells was obtained from the Gene Expression Omnibus (GEO) database, and differentially expressed miRNAs were analyzed using R language (limma package). The expressions of miR-34c-5p, miR-199a-5p, miR-324-5p, miR-361-5p, RUNX2, OCN and Bcl-2 were determined by qRT-PCR and Western blot. ELISA, Alizarin red staining and CCK-8 were used to detect the ALP content, calcium deposition and proliferation of BMSCs. The targeted binding sites between miR-34c-5p and Bcl-2 were predicted by the Target database and verified using dual-luciferase reporter assay. MiR-34c-5p expression was higher in rabbit lumbar fusion model and differentiated BMSCs than normal rabbit or BMSCs. The content of ALP and the deposition of calcium increased with the osteogenic differentiation of BMSCs. Upregulation of miR-34c-5p reduced cell proliferation and promoted ALP content, calcium deposition, RUNX2 and OCN expression compared with the control group. The effects of miR-34c-5p inhibitor were the opposite. In addition, miR-34c-5p negatively correlated with Bcl-2. Upregulation of Bcl-2 reversed the effects of miR-34c-5p on ALP content, calcium deposition, and the expressions of RUNX2 and OCN. @*Conclusions@#miR-34c-5p could promote osteogenic differentiation and suppress proliferation of BMSCs by inhibiting Bcl-2.

Outcomes of chronic total occlusions in coronary arteries according to three therapeutic strategies: a meta-analysis with 6985 patients from 8 published observational studies

Abstract Objective: To perform a systematic review and meta-analysis of studies comparing coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), and medical treatment (MT) in patients with chronic total occlusions (CTOs). Methods: We identified eligible observational studies published in the China National Knowledge Infrastructure database, PubMed, Excerpta Medica database, Google Scholar, Cochrane Library, Web of Science, and "Clinical trials" registration from 1999 to October 2018. Main outcome measures were all-cause mortality, cardiac death, major adverse cardiac events (MACEs), and myocardial infarction (MI). Results: There were eight observational studies including 6985 patients. Patients' mean age was 64.4 years. Mean follow-up time was 4.3 years. Comparing with MT (2958 patients), PCI (3157 patients) presented decreased all-cause mortality (odd ratio [OR]: 0.46, 95% confidence interval [CI]: 0.36-0.60; P<0.001), cardiac death (OR: 0.40, 95% CI: 0.31-0.52; P<0.001), MACE (OR: 0.55, 95% CI: 0.43-0.71; P<0.001), and MI (OR: 0.40, 95% CI: 0.26-0.62; P<0.001). Comparing with MT, CABG (613 patients) presented lower all-cause mortality (OR: 0.50, 95% CI: 0.36-0.69; P<0.001) and MACE (OR: 0.50, 95% CI: 0.26-0.96; P=0.04), but not lower MI (OR: 0.23, 95% CI: 0.03-1.54; P=0.13) and cardiac death (OR: 0.83, 95% CI: 0.51-1.35). Comparing with CABG, PCI did not present decreased risk for those outcomes. Conclusions: PCI or CABG was associated with better clinical outcome in patients with CTO than MT. PCI is not better than CABG in decreasing mortality, MI, cardiac death, and MACE in coronary CTO patients.

Association between C1q gene polymorphisms and autoimmune thyroid diseases

ABSTRACT Objective In the present study, we aimed to assess the associations of C1q gene polymorphisms with autoimmune thyroid diseases (AITD) susceptibility. Subjects and methods A set of 1,003 AITD patients (661 with Graves' disease and 342 with Hashimoto's thyroiditis) and 880 ethnically- and geographically-matched controls from Chinese Han population were included. Five common single nucleotide polymorphisms (SNPs) (rs294185, rs292001, rs682658, rs665691 and rs294179) in C1q gene locus were genotyped. Frequencies of genotypes and alleles were compared between patients and controls, and haplotype analysis was also performed. Results There was no statistically significant difference between AITD patients and controls in the frequencies of alleles of rs294185 (P = 0.41), rs292001 (P = 0.71), rs682658 (P = 0.68), rs665691 (P = 0.68) and rs294179 (P = 0.69). There was also no statistically significant difference between AITD patients and controls in the frequencies of genotypes of rs294185 (P = 0.72), rs292001 (P = 0.89), rs682658 (P = 0.83), rs665691 (P = 0.90) and rs294179 (P = 0.43). Stratified analyses showed that none of those five SNPs in C1q gene were associated with Graves' disease or Hashimoto's thyroiditis (all P values > 0.05). Haplotype analysis revealed that there were no obvious genetic associations of C1q gene polymorphisms with AITD susceptibility. Conclusions We, for the first time, identified the associations between C1q gene SNPs and AITD, and our findings suggested that five common SNPs in C1q gene were not associated with AITD susceptibility in Chinese Han population.

The mosquito Aedes albopictus is the primary vector for dengue virus transmission in Fujian Province.Despite that active dengue surveillance has been launched in several sites since 2005,the genetic diversity of A.albopictus from these sites remains exclusive.In this study,mosquito pools collected from dengue surveillance sites during 2015-2016 were randomly selected,the full-length mitochondrial cytochrome C oxidase subunit Ⅰ (mtDNA-COⅠ) were amplified and sequenced.Preliminary sequence alignment of 12 amplicons with the reference sequence indicated 99 ％ homology at nucleotide level,due to varia tions at 9 nucleotide sites.Three haplotypes,namely H02,H03 and H08,were determined based on phylogenetic analysis with 72 reference sequences of known haplotypes.These observations facilitate surveillance and control of arboviral diseases in Fujian.

Discovery of a small-molecule bromodomain-containing protein 4 inhibitor that induces AMP-activated protein kinase-modulated autophagy-associated cell death in breast cancer / 中国药理学与毒理学杂志

OBJECTIVE To discover a small-molecule bromodomain-containing protein 4 (BRD4) inhibitor that induces AMP- activated protein kinase- modulated autophagy- associated cell death in breast cancer and exploreits potential mechanisms. METHODS BRD4 interactors were analyzed by PPI network prediction and The Cancer Genome Atlas (TCGA) analysis. The interaction between BRD4 and AMPK was confirmed by co- immunoprecipitation assay. Novel BRD4 inhibitors were designed and synthesized based upon pharmacophore analysis of BRD4 (1), then screened by anti-proliferative activity and Alpha Screen of BRD4 (1). The selectivity of the best candidate compound 8f was validated by co-crystallization, FRET assay and co-immuno precipitation assay. The mechanisms of 8f were investigated by fluorescence microscopy, electron microscopy, Western blotting, immunocy?tochemistry, siRNA and GFP-mRFP-LC3 plasmid transfections, as well as immunohistochemistry and immunofluorescence. Potential mechanisms were discovered by iTRAQ- based proteomics analysis and the therapeutic effect of 8f was assessed by xenograft breast cancer mouse and zebrafish models. RESULTS We identified that BRD4 interacted with AMPK, which was remarkably downregulated in breast cancer. We next designed and synthesized 49 candidate compounds, and eventually discovered a selective small-molecule inhibitor of BRD4 (8f). Subsequently, 8f was discovered to induce autophagy-associated cell death (ACD) by BRD4- AMPK interaction, and thus activating AMPK- mTOR- ULK1-modulated autophagic pathway in breast cancer cells. Interestingly, the iTRAQ- based proteomics analyses revealed that 8f induced ACD pathways, involved in HMGB1, VDAC1/2 and eEF2. Moreover, 8f displayed a therapeutic potential on both xenograft breast cancer mouse and zebrafish models. CONCLUSION We discovered a novel small-molecule inhibitor of BRD4 that induces BRD4-AMPK-modulated ACD in breast cancer, which may provide a candidate drug for future cancer therapy.

Observations on the Application of She Medicine Therapy to Rapid Rehabilitation after Lumbar Spinal Endoscopic Surgery / 上海针灸杂志

Objective To investigate the clinical efficacy of She medicine therapy in rehabilitation after endoscopic surgery for lumbar intervertebral disc herniation.Methods Sixty patients with lumbar intervertebral disc herniation were allocated, using random number table method following registration order, to treatment and control groups, 30 cases each. The treatment group received She medicine therapy and the control group, oral administration of conventional drugs. The excellent and good rate was observed in the two groups after treatment. Post-treatment active straight leg raising times and analgesic dosages were compared between the two groups.Results Active straight leg raising time was significantly advanced (P<0.01) and the number of potent analgesic uses was significantly decreased (P<0.01) in the treatment group after endoscopic surgery for lumbar intervertebral disc herniation. The excellent and good rate was 93.3％ in the treatment group and 80.0％ in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion She medicine therapy can help rapid rehabilitation after endoscopic surgery for lumbar intervertebral disc herniation.
