ABSTRACT

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. It is known that aucubin (AU) exerts anti-inflammatory activity, but its effects and mechanisms in RA are unclear. This study investigated the anti-inflammatory effects and mechanisms of AU in vivo and in vitro. Human fibroblast-like synoviocyte cells from patients with RA (HFLS-RA), RAW264.7 cells, and MC3T3-E1 cells were used to evaluate the effects of AU on migration, invasion, apoptosis, osteoclast differentiation and production. Immunofluorescence was used to observe nuclear translocation of nuclear factor (NF)-κB, the double luciferase reporter gene method was used to observe NF-κB-p65 activity in AU-treated MC3T3-E1 cells. RT-qPCR was used to measure expression of bone metabolism and inflammation-related genes, and western blot was used to measure bone metabolism and NF-κB protein expression levels. Collagen-induced arthritis (CIA) rat model was used for pharmacodynamics study. Arthritis indexes were measured in the ankle and knee, histological staining and Micro-computed tomography were performed on the ankle joints. Also, inflammatory factor gene expression and the levels of NF-κB-related proteins were detected as in vitro. AU effectively inhibited HFLS-RA cell migration and invasion, promoted apoptosis, and inhibited RAW264.7 cell differentiation into osteoclasts, as well as inhibited NF-κB-p65 activity in MC3T3-E1 cells. Notably, AU significantly reduced the gene expression levels of three cell-related inflammatory factors and bone metabolism factors, effectively inhibited the expression of p-Iκκα β, p-IκBα, and p-p65 proteins. In vivo, AU relieved joint inflammation, reduced related inflammatory factors, and inhibited NF-κB signaling. It could be used to treat RA-related synovial inflammation and bone destruction through the NF-κB pathway.

ABSTRACT

In contrast to traditional representational perspectives in which the motor cortex is involved in motor control via neuronal preference for kinetics and kinematics, a dynamical system perspective emerging in the last decade views the motor cortex as a dynamical machine that generates motor commands by autonomous temporal evolution. In this review, we first look back at the history of the representational and dynamical perspectives and discuss their explanatory power and controversy from both empirical and computational points of view. Here, we aim to reconcile the above perspectives, and evaluate their theoretical impact, future direction, and potential applications in brain-machine interfaces.

ABSTRACT

OBJECTIVE@#To analyze clinical response of the Rituximab-based chemotherapy and prognostic features in patients with primary gastric diffuse large B-cell lymphoma (PGDLBCL).@*METHODS@#From June 2008 to December 2020, the data of 53 PGDLBCL patients were analyzed retrospectively.@*RESULTS@#The median age was 46(25-77) years old in 53 patients including 35 males and 18 females. Stomachache is the most common symptom. The diagnosis were confirmed in 47 patients by endoscopic biopsy and 6 patients by surgery. Twenty-six patients had Ⅰ/Ⅱ1 stage (Lugano staging system) disease and 27 cases had II2/IV stage disease. All patients were treated with chemotherapy, including RCHOP (25/53) and R-DA-EPOCH (28/53). Complete remission rate was 79.2%(42/53). The 3-year and 5-year overall survival (OS) rates were 77.4% and 69.8%. Univariate analysis showed that lactate dehydrogenase(LDH), Lugano stage and lesion size affected OS. Multivariate Cox regression analysis revealed that IPI score and Lugano stage were independent prognosis risk factors affecting OS. The patients in the R-DA-EPOCH group presented better survival outcomes than those in the RCHOP group with late stage (P5-year OS=0.035).@*CONCLUSION@#Rituximab in combination with chemotherapy is the backbone of therapy for PGDLBCL. IPI score and Lugano stage are independent prognosis risk factors affecting OS of PGDLBCL. R-DA-EPOCH can be superior to R-CHOP as a first-line regimen in PGDLBCL patients with late stage.

ABSTRACT

Objective: To investigate the diagnosis value of myocardial work (MW) in evaluating left ventricular global systolic function among acute myocardial infarction (AMI) patients with preserved ejection fraction (LVEF). Methods: This study was a diagnostic trial in a prospective case-control design. AMI patients with preserved LVEF were enrolled as AMI(LVEF>50%) group and age and sex-matched healthy individuals undergoing healthy checkup in our hospital were collected as control group. Two-dimensional dynamic images, including standard apical two-chamber, long-axis and four-chamber views in 3 consecutive cardiac cycles were acquired. General clinical data, routine echocardiography and myocardial work parameters were obtained from all subjects. The indices were compared between the two groups. Intra-observer and inter-observer repeatability of myocardial work parameters were evaluated by intra-group correlation coefficient (ICC). Receiver operator characteristic (ROC) curve was used to determine the diagnostic value of global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE) and global work index (GWI) on the reduction of left ventricular global systolic function in AMI(LVEF>50%) group. Results: There were 30 patients in AMI(LVEF>50%) group, the age was (67.3±9.7)years, and 14 cases were female(46.7%). Thirty participants were included in the control group, the age was (68.1±8.6)years, and 12 cases were female (40.0%). Compared with the control group, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), interventricular septum thickness (IVSD), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), peak early diastolic velocity of mitral orifice/tissue Doppler velocity of posterior mitral annulus (E/e), left ventricular mass (LVM), left ventricular mass index (LVMI) were significantly higher, while E and e values were significantly lower in AMI (LVEF>50%) group (all P<0.05). Compared with the control group, GCW ((1 145.9±440.1)mmHg% (1 mmHg=0.133 kPa) vs. (1 425.7±355.4)mmHg%), GWE ((80.9±9.5)% vs. (87.3±5.5)%), GWI ((1 001.3±416.2)mmHg% vs. (1 247.6±341.7)mmHg%) and the absolute value of long axis integral strain (GLS) ((8.5±3.4)% vs. (11.4±3.7)%) were significantly lower, while peak strain dispersion(PSD)((101.3±66.4)ms vs. (74.7±31.9)ms) was significantly higher in AMI(LVEF>50%) group (P all<0 05). There was no significant difference in GWW((177.2±71.1)mmHg% vs. (155.7±64.6)mmHg%) between the two groups (P>0.05). The reproducibility of GCW, GWW, GWE and GWI within and between observers were satisfactory (all ICC>0.75). ROC curve analysis showed that all four parameters, GCW, GWW, GWE, and GWI, could be used for the diagnosis of reduced left ventricular systolic function in patients with AMI (LVEF>50%), and their areas under the ROC curve were 0.896,0.929,0.808,0.862. Conclusion: Myocardial work assessment is valuable on diagnosing left ventricular global systolic function reduction in AMI patients with preserved LVEF.

ABSTRACT

Objective:To explore the status and correlates of sleep quality in hospitalized patients with schizophrenia.Methods:A total number of 269 schizophrenia inpatients were recruited from 7 hospitals including Peking University Sixth Hospital, Zhumadian Second People′s Hospital and Liaocheng Fourth People′s Hospital from August 2019 to March 2021. The Brief Psychiatric Rating Scale (BPRS), the Pittsburgh Sleep Quality Index (PSQI), the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder Scale (GAD-7) and the suicide module of Mini-International Neuropsychiatric Interview were evaluated. Poor sleep quality was determined by the score of more than 5 according to PSQI, all patients were divided into groups of poor and normal sleep quality. The general demographic data and clinical characteristics of two groups were compared, and the correlates of sleep quality were obtained by Spearman correlations and multiple logistic regression.Results:The prevalence of poor sleep quality in schizophrenia inpatients was up to 44.6% (120/269). Compared with normal sleep quality group, inpatients with poor sleep quality had higher rates of alcohol consumption history, use of benzodiazepines (BZDs) and current suicide risk, and BPRS total score, factor scores (thinking disorders, anxious-depression, hostile-suspiciousness and activation), PHQ-9 and GAD-7 scores were also higher (all P<0.05). Spearman correlation analyses showed that PSQI total score were significantly positively correlated with BPRS total score ( r=0.323), PHQ-9 score ( r=0.553), GAD-7 score ( r=0.456) and current suicide risk level ( r=0.320) (all P<0.001). Multiple logistic regression showed that history of alcohol consumption ( OR=2.897, 95% CI: 1.002-8.372), use of BZDs ( OR=3.181, 95% CI: 1.548-6.534), thinking disorders ( OR=1.563, 95% CI: 1.015-2.406), comorbidity with depression ( OR=4.968, 95% CI: 1.869-13.202), and current suicide risk ( OR=2.496, 95% CI: 1.360-4.581) were independently correlated with poor sleep quality (all P<0.05). Conclusion:Poor sleep quality is common in hospitalized patients with schizophrenia, and history of alcohol consumption, use of BZDs, thinking disorders, comorbidity with depression and current suicide risk are independent correlates of poor sleep quality.

ABSTRACT

Objective:To clarify the clinical significance, diagnostic and prognostic values of circular RNA circ_0141633 and circ_0008234 in peripheral blood of pancreatic cancer, and analyze their impact on the biological function of pancreatic cancer cells.Methods:The peripheral blood samples of 97 pancreatic cancer patients and 71 healthy controls were collected, and the expression of circ_0141633 and circ_0008234 was analyzed by real-time quantitative polymerase chain reaction (qRT-PCR). The relationships between the expression of circ_0141633 and circ_0008234 and clinicopathological characteristics and prognosis of pancreatic cancer were analyzed by chi-square test, K-M survival curves and Cox proportional hazards regression model. The area under curve (AUC), sensitivity and specificity of circ_0141633 and circ_0008234 in the diagnosis of pancreatic cancer were analyzed by receiver operating characteristic (ROC) curve. The effects of circ_0141633 and circ_0008234 on the proliferation, migration, invasion and epithelial mesenchymal transformation (EMT) of Bxpc-3 cells were analyzed by methyl thiazolyl tetrazolium (MTT) method, cell scratch test, Transwell invasion and Western blot.Results:The expression of circ_0141633 and circ_0008234 in peripheral blood of pancreatic cancer patients was higher than those of healthy controls (all P<0.05). High expression of circ_0141633 and circ_0008234 was associated with higher clinical stage, lymph node metastasis and venous invasion, and were independent risk factors for poor prognosis in pancreatic cancer (all P<0.05). The overall survival rate of patients with high expression of circ_0141633 and circ_0008234 was significantly lower than that of patients with low expression of circ_0141633 and circ_0008234 (all P<0.05). The AUC of circ_0141633, circ_0008234, the combination of circ_0141633 and circ_0008234, CA19-9 in the diagnosis of pancreatic cancer was 0.70, 0.67, 0.88 and 0.82, with sensitivity of 64.32%, 60.79%, 78.22% and 73.97%, respectively. The specificity was 68.54%, 65.46%, 81.65% and 79.41%, respectively. The diagnostic efficiency of combination was superior to CA19-9, circ_0141633 and circ_0008234 alone (all P<0.05). Interfering with circ_0141633 and circ_0008234 alone could inhibit the proliferation, migration, invasion and EMT of Bxpc-3 cells, and the above inhibitory effect was more obvious after interfering with both of circ_0141633 and circ_0008234 (all P<0.05). Conclusions:The high expression of circ_0141633 and circ_0008234 in peripheral blood could be used as potential diagnostic and prognostic biomarkers of pancreatic cancer, and could promote the progression of pancreatic cancer.

ABSTRACT

Objective:To investigate the efficacy and safety of nasal continuous positive airway pressure (NCPAP) combined with inhalation of pulmonary surfactant (PS) using vibrating mesh nebulizers in the treatment of neonatal respiratory distress syndrome (RDS).Methods:A prospective study was performed on premature infants with RDS admitted to the First Affiliated Hospital of Bengbu Medical College between December 2020 and June 2021. They were randomly assigned into vibrating mesh atomization technology group and intubation-surfactant-extubation (INSURE) technology group. The two groups were treated with NCPAP combined with PS. PS in the vibrating mesh atomization technology group was inhaled into the lungs by the new vibrating mesh atomization technology, while PS in the INSURE group was injected into the lungs by endotracheal tube. The pH value, arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), mechanical ventilation via endotracheal tube (MVET) demand rate, duration of respiratory support, secondary use of PS, complications, and hospital mortality were compared between the two groups. The occurrences of adverse events in the two groups were recorded. Results:A total of 42 preterm infants were finally enrolled, including 20 cases in the vibrating mesh atomization technology group and 22 cases in the INSURE technology group. There were no significant differences in blood gas analysis and PaO 2/FiO 2 before PS administration between the two groups. One hour after PS administration, blood gas analysis and PaO 2/FiO 2 were significantly improved in both groups. Compared with the INSURE technology group, the improvement of PaO 2/FiO 2 was more obvious in the vibrating mesh atomization technology group [mmHg (1 mmHg≈0.133 kPa): 198±34 vs. 173±39, P < 0.05], but no significant difference in pH value or PaCO 2 was found between the two groups. The duration of respiratory support in the vibrating mesh atomization technology group was significantly shorter than that in the INSURE technology group (hours: 96±13 vs. 120±18, P < 0.01), but there was no statistical difference in MVET demand rate [5.0% (1/20) vs. 13.6% (3/22), P > 0.05]. The incidence of periventricular-intraventricular hemorrhage (PVH-IVH) in the vibrating mesh atomization technology group was less than that in the INSURE technology group [0% (0/20) vs. 18.2% (4/22)], but no statistical difference was found ( P > 0.05). No significant differences in the secondary use rate of PS and incidence of bronchopulmonary dysplasia (BPD) or other complications were found between the vibrating mesh atomization technology group and the INSURE technology group [5.0% (1/20) vs. 9.1% (2/22), 5.0% (1/20) vs. 4.5% (1/22), both P > 0.05]. There were no deaths or serious adverse events such as pneumothorax, pulmonary hemorrhage, periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in both groups. Conclusion:Compared with the INSURE technique, NCPAP combined with vibrating mesh atomization technology was also effective and safe in the treatment of RDS, which could significantly improve PaO 2/FiO 2 and shorten the duration of respiratory support. Thus, it was worthy of clinical popularization and application.

ABSTRACT

OBJECTIVES@#To evaluate myocardial injury in neonates born to pregnant women with pregnancy complicated by severe preeclampsia by myocardial work indices.@*METHODS@#A prospective cohort study was performed on 25 preterm infants born to the pregnant women with severe preeclampsia from June 2020 to April 2021 (severe preeclampsia group), and 25 preterm infants born to the pregnant women without severe complications in pregnancy were enrolled as the control group. Echocardiography was performed within 24 hours and at 48-72 hours and 14-28 days after birth to measure conventional parameters. Two-dimensional speckle-tracking echocardiography was performed to construct a noninvasive left ventricular pressure-strain loop based on two-dimensional myocardial strain and left ventricular systolic pressure noninvasively measured, so as to calculate myocardial work indices.@*RESULTS@#Compared with the control group, the severe preeclampsia group had significant reductions in left ventricular global work index and global constructive work within 24 hours after birth (P<0.05), a significant reduction in left ventricular global work efficiency and a significant increase in global waste work at 48-72 hours after birth (P<0.05), and a significant reduction in left ventricular global work efficiency at 14-28 days after birth (P<0.05).@*CONCLUSIONS@#Subclinical myocardial injury persists in the neonatal period in preterm infants born to pregnant women with severe preeclampsia.

ABSTRACT

OBJECTIVE@#To systematically review the therapeutic effect of acupuncture and moxibustion on postoperative gastrointestinal dysfunction (GID) of gastric cancer with meta-analysis.@*METHODS@#The articles of randomized controlled trials (RCTs) of acupuncture and moxibustion treatment for postoperative GID of gastric cancer were retrieved from the following databases from the time of database establishment to December 31, 2020, including PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database and China Biomedical Literature Database (SinoMed). RevMan5.3 software was used for meta-analysis. Using Stata16.0 software, sensitivity analysis and publication bias test were performed.@*RESULTS@#A total of 16 RCTs were included finally, including 1 360 patients, of which, there were 681 cases in the intervention group and 679 cases in the control group. Meta-analysis results showed that acupuncture and moxibustion shortened the time of first flatus (P<0.000 01, MD =-14.52, 95%CI = [-17.31, -11.74]), the time of first bowel sound (P<0.000 01, MD =-10.50, 95%CI =[-13.99, -7.01]) and the time of first defecation (P<0.000 1, MD =-13.79, 95%CI =[-20.09, -7.50]). Meanwhile, acupuncture and moxibustion shortened the time of the first food intake (P<0.000 1, MD =-3.23, 95%CI = [-3.45, -3.00]) and the hospital stay (P<0.000 01, MD =-1.94, 95%CI =[-2.20, -1.69]) after gastric cancer operation, and reduced the incidences of postoperative adverse reactions, i.e. nausea and vomiting (P =0.000 3, RR =0.43, 95%CI =[0.28, 0.68]) and abdominal distention (P =0.000 5, RR =0.41, 95%CI =[0.25, 0.68]).@*CONCLUSION@#Acupuncture and moxibustion can promote the recovery of postoperative gastrointestinal function in the patients with gastric cancer. But, for the comparison among different measures of acupuncture and moxibustion intervention, it needs more high-quality trials for a further verification.

ABSTRACT

OBJECTIVE@#To observe the effect of acupuncture combined with regular treatment and swallowing function training on pharyngeal motor, sensory function and penetration-aspiration function in patients with dysphagia after stroke.@*METHODS@#A total of 60 patients with dysphagia after stroke were randomly divided into a control group and an observation group, 30 patients in each group. Both groups were treated with conventional treatment and swallowing function training; in addition, the observation group was treated with acupuncture at Lianquan (CV 23), Fengfu (GV 16), Yifeng (TE 17). All the treatments were given once a day, 5 days a week, for totally 4 weeks. In the two groups, the pharyngeal motor and sensory function, penetration-aspiration scores were evaluated by fiberoptic endoscopic evaluation of swallowing (FEES), and the Kubota water swallowing test scores were assessed before and after treatment, and the clinical effects were compared.@*RESULTS@#After treatment, the pharyngeal motor and sensory function in the two groups were all higher than those before treatment (P<0.05), and those in the observation group were better than the control group (P<0.05). After treatment, the penetration-aspiration scores and Kubota water swallowing test scores in the two groups were all lower than those before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). The total effective rate was 93.3% (28/30) in the observation group, which was better than 73.3% (22/30) in the control group (P<0.05).@*CONCLUSION@#Acupuncture combined with regular treatment and swallowing training could improve the pharyngeal motor and sensory function, and penetration-aspiration scores in patients with dysphagia after stroke.

ABSTRACT

OBJECTIVE@#To summarize the experience in the diagnosis and management of septic arthritis after anterior cruciate ligament reconstruction.@*METHODS@#A retrospective review was conducted of all the arthroscopic anterior cruciate ligament reconstructions performed at Department of Sports Medicine, Peking University Third Hospital between January 2001 and December 2020. In the study, 65 of 27 867 patients experienced postoperative septic arthritis. The incidence, presentation, laboratory results, treatment, and outcome of all the infected patients were analyzed. The experiences of diagnosis and management of septic arthritis after anterior cruciate ligament reconstruction were summarized.@*RESULTS@#A total of 27 867 anterior cruciate ligament reconstructions were performed at our department between January 2001 and December 2020. In the study, 65 (0.23%) patients were identified with postoperative septic arthritis. The most common symptoms of the infected patients were fever (38.7±0.5) ℃, knee swelling, pain, and restricted motion. The mean peripheral white blood cell count (WBC) was (9.2±2.6)×109/L (range 4.2×109/L-19.4×109/L), with (72.5±6.3) % (range 54.9%-85.1%) polymorphonuclear neutrophils (N). The mean erythrocyte sedimentation rate (ESR) was (59.9±24.1) mm/h (range 9-108 mm/h), C-reactive protein (CRP) was (10.9±5.7) mg/dL (range 1.2-30.8 mg/dL), and fibrinogen (FIB) level was (7.0±1.6) g/L (range 3.7-10.8 g/L). All of the laboratory results were statistically higher in the infection group compared with the normal postoperative group (P<0.001). The synovial white blood cell count (SWBC) of aspirated knee joint fluid was (45.0±29.8)×109/L (range 7.1×109-76.5×109/L). Polymorphonuclear cell percentage (PMNC) was (90.27±7.86) % (range 60%-97%). In the study, 45 patients (69.2%) had positive aspirate cultures. Microbiology showed coagulase-negative Staphylococcus (CNS) and Staphylococcus aureus (SA) were the most common bacterium (34 cases and 7 cases, individually). There were 26 methicillin-resistant Staphylococcus. Both conservative (16 patients) and operative (49 patients) treatments were effective, but conservative group had a longer recovery time (5.6 d vs. 1.6 d, P=0.042).@*CONCLUSION@#Septic arthritis after arthroscopic anterior cruciate ligament reconstruction is a rare but potentially devastating complication. The correct diagnosis relies on synovial fluid analysis and bacterial culture. Our proposed treatment protocol is arthroscopic debridement and antibiotic therapy as quickly as possible.

ABSTRACT

OBJECTIVE@#To make a retrospective analysis of the situation and process of treating skiers' injuries in the medical station of the Wanlong ski resort in Chongli and the nearest treatment hospital, and to provide a basis for the establishment and optimization of the treatment process between the medical station of the Winter Olympics ski resort and the nearest treatment hospital, and to gain experience for medical security of mass skiing.@*METHODS@#The data of all ski injuries in Chongli District were collected from the medical station of the Wanlong ski resort during the 2018-2019 snow season (November 2018 to April 2019) and the nearest treatment hospital during two periods (March 2019, and November 2019 to January 2020). The differences of injury causes, injury types, injury sites, and treatment effects of the injured skiers were analyzed.@*RESULTS@#A total of 755 cases of ski injuries were recorded in the medical station of Wanlong ski resort, the estimated incidence of injury was 2.02‰ per day. The nearest treatment hospital treated a total of 838 injured skiers from different ski resorts in Chongli District in the two periods. In the records of the ski resort medical station, the main causes of injury were technical defects and turnovers (53.6%). Knee joint injury rate was the highest (18.7%), followed by head and neck (12.9%) and lower limb (11.9%). The number of injuries on intermediate roads was the highest (40.0%), the greatest number of injuries (81.2%) occurred when the age of skiing was less than 5 years. In the records of the nearest treatment hospital, the injury types were fracture or fissure fracture, contusion and trauma, and muscle and soft tissue injury, accounting for 30.5%, 27.4%, and 21.2% respectively. 9.6% of the injured took the snow field ambulance to the hospital, and 50% of them suffered from fractures or fissure fractures.@*CONCLUSION@#The injury rate of skiing in the 2018-2019 snow season of the Wanlong ski resort in Chongli was higher than that reported by foreign literature. Severe trauma (including severe fractures and concussions) could occur and patients needed to be transferred to the nearest hospital for treatment. The ski resort medical station and the nearest treatment hospital should be strengthened with adequate medical staff and equipment, and promote cooperation in the timely referral of seriously injured patients, the organization and construction of ski patrols and the medical security of large-scale competitions, thus playing an important role in forming a grassroots network of medical security and treatment system for skiing.

ABSTRACT

Objective:To investigate the risk factors of postpartum embryo residues associated with uterine arteriovenous fistula.Methods:From January 2000 to December 2020, 26 cases of postpartum embryo residue complicated with uterine arteriovenous fistula in Tangshan Maternal and Child Health Hospital were selected as the case group, and 32 cases of postpartum embryo residue without uterine arteriovenous fistula were selected as control group.Both the case group and the control group had embryo residue in cesarean scar.Univariate and multivariate logistic analysis were used to screen the risk factors of postpartum embryo residue combined with uterine arteriovenous fistula.Results:There were 26 patients in the case group, including 3 patients after medical abortion, 17 patients after artificial abortion, 2 patients after cesarean section, and 4 patients after mid-term induced labor.There were 32 patients in the control group, including 7 patients after medical abortion, 11 patients after induced abortion, 8 patients after cesarean section, and 6 patients after mid-term induced labor.There were 11 patients in the case group and 3 patients in the control group.Univariate analysis showed that: the occurrence of postpartum embryo residue combined with uterine arteriovenous fistula was related to the time of vaginal bleeding, HCG value before and after treatment, hemoglobin value before treatment, platelet count and residual embryo area(all P<0.05). Multivariate regression analysis showed that the increase of hCG before treatment ( OR 20.319, 95% CI 1.348-306.187) and the decrease of hemoglobin before treatment ( OR 0.870, 95% CI 0.788-0.960) were the independent risk factors of postpartum embryo residue combined with uterine arteriovenous fistula (all P<0.05). Conclusion:The risk factors of uterine arteriovenous fistula in postpartum embryo residue patients with elevated hCG value and decreased hemoglobin value before treatment should be highly vigilant to reduce the rate of clinical missed diagnosis.

Objective:To investigate the predictive value of the ischemic stroke predictive risk score (iScore) and serum homocysteine (Hcy) for early neurological deterioration (END) in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke admitted to the Affiliated Hospital of Jining Medical University from July 2018 to June 2020 were enrolled retrospectively. END was defined as the National Institutes of Health Stroke Scale (NIHSS) score within 7 d after admission increased by ≥2 from the baseline. Multivariate logistic regression analysis was used to determine the independent correlations of iScore and serum Hcy level with END, and then the receiver operating characteristics (ROC) curve was used to evaluate the individual and combined predictive values of iScore and serum Hcy for END. Results:A total of 398 patients with acute ischemic stroke were enrolled, including 241 (60.6%) males, aged 65.02±12.17 years. The baseline NIHSS score was 12.15±5.67 and iScore was 124.58±37.51, and 103 patients (25.9%) developed END. Univariate analysis showed that there were significant differences in atrial fibrillation, fasting blood glucose, serum Hcy, stroke etiology type (large artery atherosclerosis and small artery occlusion), baseline NIHSS score and iScore between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for age, atrial fibrillation, fasting blood glucose, and stroke etiology type, the iScore (odds ratio [ OR] 1.016, 95% confidence interval [ CI] 1.009-1.040; P=0.004), serum Hcy ( OR 1.191, 95% CI 1.075-1.588; P<0.001) and baseline NIHSS score ( OR 1.289, 95% CI 1.101-1.613; P=0.023) had significant independent correlation with END. ROC curve analysis showed that the area under the curve of iScore combined with serum Hcy for predicting END was 0.859 (95% CI 0.820-0.898; P<0.001), which was significantly higher than that of iScore or serum Hcy alone ( P<0.001). The sensitivity and specificity of combined prediction were 81.55% and 85.76%, respectively. Conclusion:The iScore combined with serum Hcy has higher predictive value for END in patients with acute ischemic stroke.

ABSTRACT

ObjectiveTo provides suggestions to improve the mental health of the medical staff by investigation and effect analysis of mental health status of the medical staff in the public medical institutions in Shanghai. MethodsTo conducted a survey of medical staff in public medical institutions including tertiary general hospitals and tertiary specialized hospitals in Shanghai, using random stratified sampling method. The stratified standard includes hospital classification, title, and practice type. ResultsTotally 3 437 valid questionnaires were collected. Depression, anxiety and compulsion in medical staff were significantly higher than that in the general population. The top three factors that make medical staff anxious were examination, professional promotion, and academic research. The top three stressors were heavy workload, unstable working hours, and promotion pressure. Among the ways to relieve the pressure, the top three were taking a tour, talking with family or friends, and participating in recreational activities. Comparing with female medical staff, male medical staff had a lower level of resilience. ConclusionGovernment should speed up to establish the scientific performance appraisal and salary distribution system, and to guide the society to form a good atmosphere in caring for medical staff. Hospitals should promote the construction of health hospitals, and strengthen the construction of health archives. Individuals should have a healthy lifestyle and actively participate in physical examination and training that can improve mental health.

ABSTRACT

Single cell "omics" technology enables the capture of genome, transcriptome, proteome and other omics information in a high-throughput and unbiased manner at single-cell resolution, allowing the characterization of the functional state of individual cells to reveal their heterogeneity and differential responses to drug treatment. This technology has wide application in pharmacological research, facilitating drug screening, efficacy evaluation, and mechanistic studies. We envision that, in the field of traditional Chinese medicine (TCM), single cell omics technology can be applied in the identification of active ingredients and drug targets, and elucidation of drug mechanism of action. In this article, we briefly introduce the single cell omics technology - particularly single cell transcriptome sequencing, and review its application in the field of modern drug research. Based on that, we propose the concept of "single cell pharmacology" and articulate how it can be applied to transform the pharmacological research of TCM and promote TCM modernization.

ABSTRACT

Objective:To explore the research focus, frontier and trend of global reseaches about low back pain using bibliometrics and visualization technology. Methods:The researchs in the Web of Science core database from 2016 to 2020 were retrieved with the subject terms of "low back pain" and categories of rehabilitation, and analyzed with Creating Citation Reports and Analyzing Retrieval Results of Web of Science, as well as the CiteSpace. Results:A total of 2026 papers were retrieved. The total frequency of citations in the last five years was 6793. The number of papers and citations increased year by year. Most of the papers came from the countries of America, Europe and Australia; the top five university institutions also with high centrality; and funded by US National Research Fund mostly. The top ten journals for number of papers and cited frequency were mainly rehabilitation journals, and the researches mainly focused on orthopedics, sports medicine and healthcare medicine. A total of 468 key words were obtained, including 33 key words with high centrality and 29 key words with Strongest Citation Bursts. Nine papers of highly cited were suggested by Web of Science. A total of 466 references were obtained through CiteSpace, including 35 references with high centrality and 53 references with Strongest Citation Bursts. The researches of key node literature were mainly randomized controlled trails and systematic review. Conclusion:The researches of low back pain mainly focus on the mechanism and management of pain, such as central sensitization, pressure pain threshold, pain pattern classification, pain directional preference and centralization, pain physiology/neuroscience education, and nonpharmacologic strategies for comprehensive pain care; as well as the psychological and social factors, such as behavioral cognitive therapy/psychologically informed physical therapy, self-efficacy, kinesiophobia, fear avoidance, and variables and interventions related to return-to-work. The trial studies of STarT Back tool, core instruments and standardization of core outcome reporting in clinical trials, and individualized and targeted treatment, would be the global trends in the research of low back pain.

ABSTRACT

Objective:To analyze the seasonal characteristics and incidence trend of hepatitis E from 2005 to 2019 in Shanghai, and provide references for the prevention and treatment of hepatitis E. Methods:The seasonal characteristics of hepatitis E in Shanghai from 2005 to 2019 were analyzed by circular distribution method. The incidence trend of hepatitis E was analyzed by ARIMA (autoregressive moving average model). Results:The peak period of hepatitis E in Shanghai from 2005 to 2019 was from November 17 to June 9, and the peak day was on February 27. The time series shows that the optimal model is SARIMA(0,1,1)×(0,1,1)12, Akaike information criterion(AIC) and Schwartz Bayesian information criterion (SBC) are 1 243.799 and 1 250.035 respectively, and the residual is white noise sequence. The mean absolute percentage error(MAPE)between the predicted value, and the actual value of this model is 20.253%. The forecast shows a slight decrease in the number of cases of hepatitis E in 2020-2021 compared with 2019, but it is still at a high level. Conclusion:The incidence of hepatitis E in Shanghai shows a solid seasonal characteristic. Health education and prevention/control measures should be conducted well before the epidemic peak. Based on the short-term prediction, the incidence of hepatitis E would still be high. Effective prevention and control strategies should be developed, and active measures should be taken.
