OBJECTIVE:There are many kinds of biological agents for the treatment of rheumatoid arthritis in clinic,but the differences in therapeutic efficacy and safety are still unclear.The purpose of this study is to compare the differences in effectiveness and safety of different biological agents for the treatment of rheumatoid arthritis. METHODS:CNKI,VIP,WanFang,China Biomedical Literature System,PubMed,Cochrane Library,Web of Science,and Embase databases were searched to collect the randomized controlled trials on biological agents for rheumatoid arthritis that meet the requirements from inception to October 1,2022.The literature was selected by EndNote software,and the quality of the included literature was evaluated by RevMan 5.3 software.The software Stata 14.2 was used for direct meta-analysis and network meta-analysis of ACR20(American College of Rheumatology 20%response),ACR50(American College of Rheumatology 50%response),ACR70(American College of Rheumatology 70%response),erythrocyte sedimentation rate,and adverse reactions. RESULTS:Totally 39 articles were included,including 5 low-risk articles,4 high-risk articles,and the remaining 30 articles contained unknown risk bias,with a total of 13 treatment measures.The results of network meta-analysis:(1)In ACR20,infliximab combined with methotrexate(OR=5.54,95%CI:1.33-23.01,P<0.05),abatacept+methotrexate tablets(OR=3.21,95%CI:1.13-9.10,P<0.05),and tocilizumab(OR=2.95,95%CI:1.61-5.44,P<0.05)were better than methotrexate tablets.The probabilistic ranking of ACR20 was:infliximab+methotrexate tablets>abatacept+methotrexate tablets>tocilizumab>certlizumab>etanercept+methotrexate tablets.(2)In the aspect of ACR50,etanercept combined with methotrexate tablets(OR=4.04,95%CI:2.13-7.66,P<0.05),infliximab combined with methotrexate tablets(OR=4.79,95%CI:1.19-19.26,P<0.05),and tocilizumab combined with methotrexate tablets(OR=3.54,95%CI:1.36-9.22,P<0.05)had better therapeutic effects than methotrexate tablets.The probabilistic ranking of ACR50 was:etanercept+methotrexate tablets>infliximab+methotrexate tablets>tocilizumab+methotrexate tablets>tocilizumab>certlizumab+methotrexate tablets.(3)In terms of ACR70,the therapeutic effects of infliximab combined with methotrexate tablets(OR=8.00,95%CI:2.31-27.69,P<0.05),etanercept combined with methotrexate tablets(OR=4.26,95%CI:2.51-7.21,P<0.05),and tocilizumab combined with methotrexate tablets(OR=3.51,95%CI:1.82-6.80,P<0.05)were better than methotrexate tablets.The probabilistic ranking of ACR70 was infliximab+methotrexate tablets>etanercept+methotrexate tablets>tocilizumab+methotrexate tablets>certlizumab>adalimumab+methotrexate tablets.(4)In erythrocyte sedimentation rate,etanercept combined with methotrexate tablets(SMD=-9.23,95%CI:-16.55 to-1.92,P<0.05)was better than etanercept and methotrexate tablets(SMD=14.59,95%CI:7.28-21.91,P<0.05).The probabilistic ranking of erythrocyte sedimentation rate was etanercept+methotrexate tablets>infliximab+methotrexate tablets>etanercept>adalimumab+methotrexate tablets>methotrexate tablets.(5)In terms of adverse reactions,placebo(OR=0.62,95%CI:0.39-0.99,P<0.05)was better than infliximab and certlizumab(OR=0.44,95%CI:0.25-0.78,P<0.05).The probabilistic ranking of adverse reactions was placebo>infliximab>etanercept+methotrexate tablets>certlizumab>etanercept. CONCLUSION:Based on evidence from 39 randomized controlled trials,infliximab combined with methotrexate tablets(highly recommended)can be the first choice in clinic,and etanercept combined with methotrexate tablets(highly recommended)can be the second choice in terms of good effectiveness and safety.

Objective To study the bioequivalence and safety of two olmesartan medoxomil and hydrochlorothiazide tablets in Chinese healthy subjects.Methods A total of 24 healthy subjects underwent fasting and postprandial tests in a single-center,randomized,open-label,single-dose,two-formulation,two-sequence,two-period,self-cross-over controlled design.The subjects were administered a single oral dose of the test formulation and reference formulation(each containingolmesartan medoxomil 20 mg and hydrochlorothiazide 12.5 mg)in a random cross-over fashion.The plasma concentrations of olmesartan and hydrochlorothiazide were determined by LC-MS/MS.The non-compartmental model analysis of olmesartan and hydrochlorothiazide was conducted using WinNonlin 7.0 software to calculate pharmacokinetic parameters and assess bioequivalence.Results In the fasting test,the pharmacokinetic parameters of olmesartan of test and reference were as follows:Cmax were(798.35±206.78)and(664.52±168.25)ng·mL-1,AUC0-t were(4 430.71±1 294.87)and(3 976.67±1 083.54)h·ng·mL-1,AUC0-∞ were(4 551.67±1 303.06)and(4 090.37±1 103.97)h·ng·mL-1.The pharmacokinetic parameters of hydrochlorothiazide of test and reference were as follows:Cmax were(92.39±35.96)and(96.15±38.76)ng·mL-1,AUC0_t were(548.69±217.11)and(564.41±208.68)h·ng·mL-1,AUC0-∞ were(603.04±228.59)and(619.26±223.27)h·ng·mL-1.In the fed test,the pharmacokinetic parameters of olmesartan of T and R were as follows:Cmax were(583.15±149.48)and(550.57±104.76)ng·mL-1,AUC0-t were(3 585.18±952.72)and(3 292.19±904.58)h·ng·mL-1,AUC0-∞ were(3 696.05±996.55)and(3 396.30±923.41)h·ng·mL-1.The pharmacokinetic parameters of hydrochlorothiazide of test and reference were as follows:Cmax were(70.30±17.88)and(74.70±21.65)ng·mL-1,AUC0-t were(476.60±119.39)and(492.91±144.81)h·ng·mL-1,AUC0-∞ were(523.37±132.67)and(535.81±151.92)h·ng·mL-1.In fasting and fed condition,the 90％confidence interval(90％CI)of Cmax,AUC0-t and AUC0-∞ of olmesartan and hydrochlorothiazide were in 80.00％-125.00％.Conclusion The two olmesartan medoxomil and hydrochlorothiazide tablets were bioequivalent under fasting and fed conditions,and good security.

Objective To investigate the clinical characteristics of female migraine patients with patent foramen ovale(PFO)and design a risk prediction model for PFO in female migraine patients(migraineur patients PFO risk prediction model,MPRPM).Methods Female migraine patients who visited Zhongshan Hospital,Fudan University from Jun 1,2019 to Dec 31,2022 were included.Preoperative information and follow-up results after discontinuation of medication were collected.Patients were divided into PFO-positive and PFO-negative groups based on transesophageal echocardiography results.A multivariate Logistic regression model and a random forest model were constructed,and the random forest model was validated multidimensionally.Key features were selected based on the mean decrease accuracy(MDA)to construct MPRPM.Results A total of 305 female patients were included in the study,with 204 patients in the PFO-positive group and 101 patients in the PFO-negative group.Multivariate Logistic regression analysis showed that age at migraine onset,attack frequency,severe impact on life during attacks,exercise-related headaches,menstruation-induced headaches,aura migraines,and a history of cryptogenic stroke were predictive factors for PFO positivity.The random forest model effectively predicted the incidence of PFO in female migraine patients,with an AUC of 0.895(95%CI:0.847-0.943).MPRPM demonstrated a sensitivity of 71.6%and specificity of 91.1%(AUC:0.862,95%CI:0.818-0.906,P<0.001).The optimal cut-off value was 2.5 points.Patients correctly classified by the model showed a higher rate of symptom improvement compared to incorrectly classified patients(94.3%vs.82.0%,P=0.023).Conclusion We identified predictive factors for PFO in migraine patients.MPRPM can provide guidance in the diagnostic process and therapeutic decision-making for female migraine patients,assist in patient triage,and reduce the healthcare burden.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Aim To investigate the effects of dagliflozin (DAPA) on atrial tachyarrhythmia (AT) in rats with right heart failure (RHF) due to pulmonary arterial hypertension (PAH) and the underlying mechanisms. Methods Sixty male SD rats were randomly divided into four groups: control group (CTL group), model group (MCT group), MCT + low-dose DAPA intervention group (MCT + LD group) and MCT + high-dose DAPA intervention group (MCT + HD group). After 35 days of continuous intervention, the model and cardiac function evaluation, atrial structural remodelling assessment, inflammatory factor detection, and in vivo cardiac electrophysiology experiments were completed. Results DAPA reduced menn pulmonaryarterial pressure (mPAP) and menn right ventricular pressure (mRVP) in the model rats (P <0.05), attenuated the inflammatory response (P < 0.05), reduced right atrial fibrosis (P <0.05), reduced AT induction rate (P < 0.05) and mean atrial tachyarrhythmia duration (MATD) (P < 0.05), the extent of which was more pronounced in the high-dose DAPA intervention group. Conclusions DAPA can reduce AT susceptibility in PAH-induced RHF rats, and the mechanisms may be related to the inhibition of systemic inflammation and anti-atrial fibrosis by DAPA.

Objective:To investigate the effects of different concentrations of Qilan Prescription(QLP)on the proliferation and apoptosis of human PCa DU145 cells and its underlying mechanism.Methods:We treated human PCa DU145 cells with QLP at 400,200,100,50,25,12.5,6.25,3.125 or 1.56 μg/ml for 24,48 and 72 hours respectively.Then we observed the morphologi-cal changes of the cells,examined their viability by CCK-8 assay,detected their cell cycle and apoptosis by flow cytometry,and deter-mined the protein expressions of cyclin D1,Bax,Bcl-2 and cleaved-caspase 3 in the DU145 cells by Western blot,followed by com-parison of the parameters with those obtained from the blank control group.Results:QLP significantly inhibited the growth,reduced the contour clarity and adhesion ability of the DU145 cells at the concentrations of 100,200 and 400 μg/ml,and markedly decreased the activity of the cells at 200 and 400 μg/ml,most significantly at 400 μg/ml.The number of the G2-phase DU145 cells was dramat-ically increased in all the concentration groups(P＜0.01),so was the total number of apoptotic DU145 cells(P＜0.01),while that of the S-phase cells remarkably decreased in the 400 μg/ml QLP(P＜0.01)and 200 μg/ml QLP(P＜0.05)groups.The ex-pression of the cyclin D1 protein was significantly down-regulated in the 400 μg/ml QLP group(P＜0.01).That of Bcl-2 was also down-regulated(P＜0.01)while those of Bax and cleaved-caspase 3 up-regulated in the 400 and 200 μg/ml QLP groups(P＜0.01).Conclusion:QLP can inhibit the proliferation and promote the apoptosis of human PCa DU145 cells,which may be associat-ed with its effects of down-regulating the expression of the cell cycle-related protein cyclin D1,disrupting the Bax-Bcl-2 balance,and up-regulating the expression of cleaved-caspase 3.

Objective: To explore the short-term efficacy of fenestrated atrial septal defect (ASD) occulders in the treatment of pulmonary arterial hypertension (PAH). Methods: Thirty-six healthy dogs were divided into the balloon atrial septostomy (BAS)+fenestrated ASD occulders group (n=12), BAS group (n=12) and non-septostomy group (n=12). PAH was induced by intra-atrial injection of dehydrogenized monocrotaline (1.5 mg/kg) in all dogs. Animals in the BAS+fenestrated ASD occulders group underwent atrial septal puncture and fenestrated ASD occulders implantation. Animals in the BAS group underwent balloon atrial septostomy. The non-septostomy group received no surgical intervention. The hemodynamic indexes and blood N-terminal pro-B-type natriuretic peptide (NT-proBNP) of dogs were measured before modeling, 2 months after modeling, 1, 3, and 6 months after surgery, respectively. Echocardiography was performed to observe the patency of the shunt and atrial septostomy of the dogs in the BAS+fenestrated ASD occulders group and BAS group at 1, 3, and 6 months after surgery. Three dogs were sacrificed in each group at 1, 3, and 6 months after surgery, respectively. Atrial septal tissue and fenestrated ASD occulders were removed to observe the patency and endothelialization of the device. Lung tissues were obtained for hematoxylin-eosin (HE) staining to observe the inflammatory cells infiltration and the thickening and narrowing of the pulmonary arterials. Results: Among 36 dogs, 2 dogs died within 24 hours after modeling, and 34 dogs were assigned to BAS+fenestrated ASD occulders group (n=12), BAS group (n=11), and non-septostomy group (n=11). Compared with BAS group, the average right atrial pressure (mRAP) and NT-proBNP of dogs in the BAS+fenestrated ASD occulders group were significantly reduced at 3 months after surgery (P<0.05), and the cardiac output (CO) was significantly increased at 6 months after surgery, arterial oxygen saturation (SaO₂) was also significantly reduced (P<0.05). Compared with non-septostomy group, dogs in the BAS+fenestrated ASD occulders group had significantly lower mRAP and NT-proBNP at 1, 3, and 6 months after surgery (P<0.05), and higher CO and lower SaO₂ at 6 months after surgery (P<0.05). Compared with the non-septostomy group, the dogs in the BAS group had significantly lower mRAP and NT-proBNP at 1 month after surgery (P<0.05), and there was no significant difference on mRAP and NT-proBNP at 3 and 6 months after surgery (P>0.05). Echocardiography showed that there was a minimal right-to-left shunt in the atrial septum in the BAS group at 1 month after the surgery, and the ostomy was closed in all the dogs in the BAS group at 3 months after the surgery. There was still a clear right-to-left shunt in the dogs of BAS+fenestrated ASD occulders group. The shunt was well formed and satisfactory endothelialization was observed at 1, 3 and 6 months after surgery. The results of HE staining showed that the pulmonary arterials were significantly thickened, stenosis and collapse occurred in the non-septostomy group. Pulmonary microvascular stenosis and inflammatory cell infiltration in the pulmonary arterials were observed in the non-septostomy group. Pulmonary arterial histological results were comparable between BAS+fenestrated ASD occulders group and non-septostomy group at 6 months after surgery . Conclusions: The fenestrated ASD occulder has the advantage of maintaining the open fistula hole for a longer time compared with simple balloon dilation. The fenestrated ASD occulder can improve cardiac function, and it is safe and feasible to treat PAH in this animal model.
