OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Aim To investigate the effect of quercetin(Que)on podocyte inflammatory injury and the under-lying mechanism.Methods MPC5 cells were divided into normal glucose group(NG),mannitol group(MA),high glucose group(HG)and high glucose+quercetin group(HG+Que).Cell proliferation and apoptosis were detected by CCK-8 and flow cytometry.The expression of SIRT1,STAT3,apoptosis-related proteins(Bax,Bcl-2,caspase-3)and pyroptosis pro-tein GSDME was detected by Western blot.The ex-pression levels of inflammatory factors(IL-6,TNF-α,IL-18,IL-1β)in cell supernatants were detected by ELISA.Then small interfering RNA technology was used to knockdown SIRT1 expression.To further eval-uate the biological significance of SIRT1 in response to high glucose and Que treatment,negative control group(HG+si-NC+Que)and SIRT1 interference group(HG+si-SIRT1+Que)were added in the presence of high glucose and Que.Results Compared with the high glucose group,40 μmol·L-1 Que could alleviate the apoptosis of MPC5 cells induced by high glucose,decrease the expression of apoptosis related protein Bax and caspase-3,as well as increase the expression of anti-apoptotic protein Bcl-2;ELISA results showed that Que could decrease the expression of TNF-α,IL-6,IL-1 β and IL-18 induced by high glucose.Mechanical-ly,Que could alleviate the inhibitory effect of high glu-cose on the expression of SIRT1,and further decrease the activation of STAT3 and N-GSDME,and inhibit pyroptosis.Compared with the si-NC group,si-SIRT1 group could reverse the protective effect of Que on the high glucose induced inflammatory damage of podo-cytes,the expression of apoptotic proteins Bax and caspase-3 increased,while the expression of anti-apop-totic protein Bcl-2 decreased.At the same time,the levels of inflammatory cytokines TNF-α,IL-6,IL-1 βand IL-18 in supernatants increased,and the expres-sion of STAT3 and N-GSDME increased.Conclusion Que could inhibit pyroptosis and relieve the inflam-matory damage of podocytes through SIRT1/STAT3/GSDME pathway.

Objective To analyze the epidemiological characteristics of hepatitis A in Guangxi from 2010 to 2020, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of hepatitis A in Guangxi from 2010 to 2020. Results From 2010 to 2020, a total of 8,742 cases of hepatitis A were reported in Guangxi, with an average annual incidence rate of 1.66 /100,000. There were 5 298 male cases (60.60%), and 3,444 female cases (39.40%). The incidence rate decreased from 2.73/100 000 in 2010 to 1.38/100 000 in 2020. The onset seasonality was strong in 2010, but there was no obvious seasonality in other years. A total of 5 891 cases (67.39%) were aged from 25 to 64 years. Farmers accounted for 59.79% of the cases. A total of 7 hepatitis A outbreaks were reported during 2010-2020, including 273 cases，accounting for 3.12% of the total cases．The incidence rates of hepatitis A in Hezhou (3.97/100 000), Wuzhou (2.98/100 000), Hechi (2.44/100 000), Guigang (2.00/100 000) and Beihai (1.79/100 000) were relatively higher than other places. Conclusion The number of reported hepatitis A cases in Guangxi has been declining year by year, and the prevention and control measures of hepatitis A vaccine prevention are effective. The surveillance of hepatitis A should be strengthened, and prevention and control strategies should be formulated for high-risk areas and key populations.

Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ² test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

Objective: To trace and characterize the whole genome of SARS-CoV-2 of confirmed cases in the outbreak of COVID-19 on July 31, 2021 in Henan Province. Method: Genome-wide sequencing and comparative analysis were performed on positive nucleic acid samples of SARS-CoV-2 from 167 local cases related to the epidemic on July 31, 2021, to analyze the consistency and evolution of the whole genome sequence of virus. Results: Through high-throughput sequencing, a total of 106 cases of SARS-CoV-2 whole genome sequences were obtained. The results of genome analysis showed that the whole genome sequences of 106 cases belonged to the VOC/Delta variant strain (B.1.617.2 clade), and the whole genome sequences of 106 cases were shared with the genomes of 3 imported cases from Myanmar admitted to a hospital in Zhengzhou. On the basis of 45 nucleotide sites, 1-5 nucleotide variation sites were added, and the genome sequence was highly homologous. Conclusion: Combined with the comprehensive analysis of viral genomics, transmission path simulation experiments and epidemiology, it is determined that the local new epidemic in Henan Province is caused by imported cases in the nosocomial area, and the spillover has caused localized infection in the community. At the same time, it spills over to some provincial cities and results in localized clustered epidemics.

Objective: To explore the expression of Runt-related transcription factor 1 (RUNX1) in nasal polyps (NPs) tissues and the potential role on apoptosis of primary human nasal epithelial cells (pHNECs) in NPs. Methods: The expression level of RUNX1 in NPs tissues was determined by Western blot (WB) and immunohistochemical staining (IHC). In vitro, TNF-α (20 ng/ml) was used to stimulate pHNECs to establish the apoptosis injury model. Hoechst staining was performed to observe pHNECs apoptosis by kit. Subsequently, quantitative real-time PCR (qRT-PCR) and WB were utilized to detect the expression of apoptosis-related proteins B-cell lymphoma-2 (BCL-2), BCL2-associated X (BAX) and cysteinyl aspartate specific proteinase-3 (Caspase-3) to assess the level of apoptosis. The plasmid of sh-RUNX1-6 was transfected into the pHNECs apoptosis model, then the effect of RUNX1 silence on apoptosis was evaluated by WB and flow cytometry. Statistical analysis was performed by the SPSS 19.0 and GraphPad Prism5 software. Results: The expression of RUNX1 in NPs tissue was significantly higher than that in inferior turbinates, and the difference was statistically significant (0.274±0.042 vs 0.110±0.027, t=9.675, P<0.05). Compared with the inferior turbinates, BAX and Caspase-3 expressions were increased whereas BCL-2 was decreased in NPs, and the differences were statistically significant (BAX 0.346±0.032 vs 0.302±0.037, Caspase-3 0.228±0.061 vs 0.158±0.065, BCL-2 0.090±0.047 vs 0.276±0.057, t value was 2.680, 2.361 and 7.575, respectively, all P<0.05). The expression levels of RUNX1 and apoptosis in pHNECs increased in a time-dependent manner after TNF-α exposure (P<0.05). Plasmid of sh-RUNX1-6 transfected silenced the expression of RUNX1 in pHNECs treated by TNF-α. After silencing RUNX1 in pHNECs apoptosis model, the protein levels of BAX and Caspase-3 were decreased, while the expression of BCL-2 was increased, the rate of apoptosis was decreased (P<0.05). Conclusions: RUNX1 is increased in NPs. Silencing RUNX1 can inhibit the apoptosis and reduce cell inflammatory damage of pHNECs induced by TNF-α.

Objective::To observe the effect of Bimin decoction(BMD) on nuclear factor-kappa B(NF-κB) signaling pathway and aquaporin 5(AQP5) expression in allergic rhinitis (AR) rats with lung and spleen Qi deficiency syndrome(LSQDS), in order to study the mechanism in treating AR. Method::Fifty-six SD rats were randomly divided into seven groups: control group, AR group, LSQDS AR group, BMD low dose two weeks group and four weeks group, BMD high dose two weeks group and four weeks group. The control group did not intervened, the AR group established the AR disease model with ovalbumin (OVA) as the allergen, the other five groups established the LSDQS model with smoke and senna gavage, and also established the AR disease model with OVA sensitization at the same time as the AR group. After the model was established successfully, four BMD intervention groups were separately given low dose BMD (11.3 g·kg^-1) for 2 weeks and 4 weeks, and high dose BMD (22.6 g·kg^-1) for 2 weeks and 4 weeks. To observe the general situation of the rats, hematoxylin eosin (HE) staining was used to observe the pathological changes of the nasal mucosa, immunohistochemistry and Western blot were used to detect the expression levels of NF-κB and AQP5, real-time fluorescent quantitative polymerase chain reaction technique (Real-time PCR)was used to detect mRNA levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6). Result::The typical AR symptoms were found in AR rats, the AR symptoms and lung and spleen Qi deficiency symptoms were found in AR rats with LSQDS at the same time, and the AR symptoms and lung and spleen Qi deficiency symptoms were significantly improved after the intervention of BMD. Compared with the control group, the typical histopathological changes of nasal mucosa were found in AR group and LSQDS AR group, with a higher behavioral score (P<0.05), and the expression of NF-κB and AQP5 protein increased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA increased (P<0.05). Compared with AR group, the pathological changes of nasal mucosa in LSQDS AR group were more serious, and the expression of NF-κB protein in nucleus increased (P<0.05), the expression of TNF-α and AQP5 mRNA increased (P<0.05). Compared with LSQDS AR group, the pathological changes of nasal mucosa in the groups which interfered by BMD were improved, and the expression of NF-κB and AQP5 protein decreased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA decreased (P<0.05). Compared with BMD low-dose two-week group, the expression of NF-κB protein in nucleus decreased (P<0.05) in BMD high dose four week group. Conclusion::Compared with AR group, the AR condition of the rats with LSQDS is more serious under the same allergen stimulation, BMD can treat AR and reduce the over secretion of glands, which may be related to inhibit the expression of AQP5 by inhibiting the NF-κB signaling pathway.
