RESUMO
Objective:To explore the expression levels of serum triple domain 35 (TRIM35) and tumor necrosis factor receptor associated factor 3 (TRAF3) in patients with acute pancreatitis (AP) and their correlation with the severity and prognosis of the disease.Methods:Using a prospective research method, 93 patients with AP (observation group) were selected from July 2020 to September 2022 in Qinghai Red Cross Hospital, including 40 cases of mild acute pancreatitis (MAP), 29 cases of moderate to severe acute pancreatitis (MSAP) and 24 cases of severe acute pancreatitis (SAP). During the same period, 40 healthy individuals who underwent physical examinations were selected as healthy control group. The serum TRIM35 and TRAF3 levels were detected by real time fluorescence quantitative polymerase chain reaction (RT-qPCR). The survival status after 28 d of admission was followed up. The correlation was analyzed by Pearson method. Multivariate Logistic regression analysis was used to analyze the relationship between serum TRIM35 and TRAF3 levels and the prognosis in patients with AP. The efficacy of serum TRIM35 and TRAF3 in predicting the prognosis in patients with AP was evaluated by the receiver operating characteristics (ROC) curve.Results:The serum TRIM35 and TRAF3 levels in observation group were significantly higher than those in healthy control group (3.76 ± 1.36 vs. 1.02 ± 0.19 and 5.37 ± 2.18 vs. 1.04 ± 0.16), and there were statistical differences ( P<0.01). The serum TRIM35 and TRAF3 levels in patients with MSAP and SAP were significantly higher than those in patients with MAP (4.11 ± 1.73 and 4.96 ± 1.47 vs. 2.79 ± 1.04, 5.43 ± 2.15 and 7.01 ± 2.85 vs. 4.35 ± 1.79), the indexes in patients with SAP were significantly higher than those in patients with MSAP, and there were statistical differences ( P<0.05). The follow-up results showed that 11 cases died and 82 cases survived. The serum TRIM35 and TRAF3 levels in death patients were significantly higher than those in surviving patients (4.94 ± 1.01 vs. 3.60 ± 1.67 and 7.08 ± 1.43 vs. 5.14 ± 2.57), and there were statistical differences ( P<0.05). Pearson correlation analysis result showed that serum TRIM35 level was positive correlation with serum TRAF3 level in patients with AP ( r = 0.483, P<0.01). Multivariate Logistic regression analysis result showed that serum TRIM35 and TRAF3 levels were the independent risk factors of prognosis in patients with AP ( OR = 1.86 and 1.37, 95% CI 1.12 to 3.09 and 1.02 to 1.82, P<0.05). ROC curve analysis result showed that the area under the curve of serum TRIM35 combined with TRAF3 levels for evaluating the prognosis in patients with AP was significantly larger than serum TRIM35 and TRAF3 alone (0.85 vs. 0.81 and 0.81, Z = 0.03 and 0.04, P<0.05). The optimal cutoff values of serum TRIM35 and TRAF3 levels were 4.90 and 6.11. Conclusions:The serum TRIM35 and TRAF3 levels in patients with AP are significantly elevated, and are related to the severity of the condition. The serum TRIM35 and TRAF3 levels are independent risk of prognosis in patients with AP, and their combined detection is more valuable in evaluating the prognosis in patients with AP.

RESUMO
Objective:To investigate the clinical efficacy of recombinant human epidermal growth factor combined with sodium hyaluronate eye drops in the treatment of cataracts after multifocal intraocular lens implantation and its effect on inflammation factors in tears and tear film stability.Methods:A total of 86 patients with cataracts who underwent multifocal intraocular lens implantation at Jinan 2 nd People's Hospital from July 2020 to January 2023 were included in this randomized controlled study. These patients were randomly divided into a control group and a combined group, with 43 patients in each group. Patients in the control group were administered sodium hyaluronate eye drops postoperatively, while patients in the combined group received a combination of recombinant human epidermal growth factor and sodium hyaluronate eye drops. All patients were treated for 1 month. Before and after treatment, the levels of inflammatory factors in tears, tear film stability-related indicators, and corneal endothelial cells were measured and compared between the two groups. Additionally, any adverse reactions experienced by the patients were recorded throughout the treatment period. Results:After treatment, the levels of interleukin-6 and tumor necrosis factor-α in the tear fluid of the combined group were (17.91 ± 2.45) μg/L and (72.14 ± 8.43) μg/L, respectively. These values were significantly lower than those in the control group, which were (24.63 ± 3.05) μg/L and (86.97 ± 9.85) μg/L, respectively ( t = 11.26, 7.50, both P < 0.001). Additionally, the fluorescein staining score for corneal damage in the combined group was (2.34 ± 0.37) points. This was significantly lower than the score of (3.42 ± 0.48) points observed in the control group ( t = 11.69, P < 0.001). Tear break-up time and Schirmer I Test in the combined group were (8.68 ± 0.96) seconds and (9.31 ± 1.04) mm/5 minutes, respectively. These values were significantly higher than those in the control group, which were (7.81 ± 0.89) seconds and (7.14 ± 0.86) mm/5 minutes, respectively ( t = -4.36, -10.54, both P < 0.001). Furthermore, the corneal endothelial cell density and the proportion of hexagonal cells in the combined group were (2 514.09 ± 259.31) counts/mm 2 and (41.67 ± 5.05)%, respectively. These values were significantly higher than those in the control group, which were (2 244.82 ± 253.37) counts/mm 2 and (36.75 ± 4.96)% in the control group ( t = -4.87, -29.45, both P < 0.001). The incidence of adverse reactions in the combined group was 11.63% (5/43), which was significantly higher than 6.98% (3/43) in the control group ( χ2 = 0.55, P > 0.05). Conclusion:The combination of recombinant human epidermal growth factor with sodium hyaluronate eye drops following multifocal intraocular lens implantation in patients with cataracts effectively decreases the levels of inflammatory factors in tear fluid. This treatment regimen also enhances tear film stability, promotes the repair of injured corneal tissue, and is highly safe.

RESUMO
Objective:To establish a reliable,stable and clinically realistic model of blunt contusion injury to the rat skele-tal muscle. Method:A model of the rat gastrocnemius muscle blunt contusion injury was established by using a weight of 170g,a height of 70cm and a spring with a diameter of 0.5cm at the bottom to buffer the polymeric strik-ing part and guide the fall to hit for 5 consecutive times.The gait changes of rats were evaluated by CatWalk analysis system at 0h,12h,24h,3 days,7 days and 14 days after modeling;local histopathological changes were observed by HE staining and local ultrastructural changes were observed by transmission electron micros-copy.Enzyme-linked immunosorbent assay(ELISA)was used to detect the changes of tumor necrosis factor-α(TNF-α)in local tissues. Result:Compared with the blank group,the mean speed and maximum speed change rate of the model group were significantly decreased,and the difference was statistically significant(P＜0.001);compared with the normal foot group,the maximum contact area,footprint area and standing phase duration of the limb of the injured limb group were significantly decreased,and the difference was statistically significant(P＜0.05).A large infiltration of inflammatory cells and massive lysis necrosis of muscle fibers were observed on HE stain-ing after 3 days.By 14 days,although scar tissue was still present,tissue repair with HE staining was almost indistinguishable from that of the blank group.Vacuolation was observed in part of the sarcoplasmic reticulum at 0h after the blow,and lysis of muscle fibers and part of the sarcoplasmic reticulum at 3 days with in-creased inflammatory response which basically returned to normal by 14 days.The TNF-α level began to rise gradually and reached a peak from 0h to 12h after injury,and remained higher level from 12h to 72h,and the difference was statistically significant compared with the blank group(P＜0.05),and basically returned to the normal level by 14 days. Conclusion:The model can cause moderate damage of skeletal muscle in rats,with a 14-day natural recovery time at least.It can provide as one of the methods for for the establishment of the rat skeletal muscle blunt contusion model.

Objective To investigate the influences of arctigenin(ATG)on ventricular remodeling and inflammatory reaction in chronic heart failure(CHF)rats,and to analyze its potential mecha-nism.Methods A total of 79 SD rats were randomly divided into sham operation group(n=12),and the remaining rats were inflicted with abdominal aortic coarctation to establish a rat CHF model.After modeling,60 CHF rats were randomly divided into CHF group,low and high dose ATG group(ATG-L and ATG-H groups,10 and 20 mg/kg,respectively),ATG+NC group[20 mg/kg ATG+100 μl high mobility group protein B1(HMGB1)negative control plasmid],and ATG+HMGB1 group(20 mg/kg ATG+100 pl HMGB1 overexpression plasmid),with 12 rats per group.After 4 weeks of corresponding intervention,heart function,levels of B-type brain na-triuretic peptide(BNP),N-terminal B-type brain natriuretic peptide precursor(NT-proBNP)andIL-6 and TNF-α,heart mass index(HMI)and left ventricular mass index(LVMI),pathological changes of myocardial tissue,cross-sectional area of myocardial cells and myocardial collagen vol-ume fraction(CVF)and protein expression of HMGB1/Toll-like receptor 4(TLR4)/NF-κB sig-naling pathway in left ventricular myocardial tissue were measured.Results Compared with the sham operation group,myocardial tissue HMGB1(0.42±0.05 vs 0.15±0.02)and TLR4(0.70± 0.09 vs 0.21±0.04)protein levels,and phosphorylated NF-κB p65(p-NF-κB p65)/NF-κB p65(0.73±0.09 vs 0.26±0.05)protein ratio were obviously increased in the CHF group,while the left ventricular ejection fraction(LVEF)and left ventricular short-axis fractional shortening(LVFS)were obviously decreased(P＜0.05).Myocardial tissue HMGB1(0.33±0.04、0.24±0.04 vs 0.42±0.05)and TLR4(0.56±0.06、0.41±0.05 vs 0.70±0.09)protein levels,and p-NF κB p65/NF-KB p65(0.61±0.08、0.49±0.06 vs 0.73±0.09)protein ratio were decreased,and the LVEF and LVFS were increased in the ATG-L group and ATG-H group than the CHF group(P＜0.05).Overexpression of HMGB1 obviously attenuated the inhibitory effects of ATG on HMGB1/TLR4/NF-κB signaling pathway,ventricular remodeling,and inflammatory reaction in CHF rats(P＜0.05).Conclusion ATG may suppress ventricular remodeling in CHF rats by in-hibiting HMGB1/TLR4/NF-κB signaling inflammatory pathway.
RESUMO
As a new treatment option after conventional corticosteroids and immunomodulatory drugs, biologics have been widely used in the clinical management of non-infectious uveitis in many countries due to their approved efficacy and safety. Anti-tumor necrosis factor-alpha monoclonal antibody is the most commonly used one. However, the guidance on its standardized application is lacking. The Ocular Immunology Group of Immunology and Rheumatology Academy in Cross-Straits Medicine Exchange Association compiled the Chinese expert consensus on treatment of non-infectious uveitis with anti-tumor necrosis factor-alpha monoclonal antibody. This evidence-based consensus is made according to the principle of consensus building and combines the clinical experience of the experts. Twelve recommendations are formatted on the application of Adalimumab and Infliximab. The interpretation of this consensus point will help improve the normative and effective application of anti-tumor necrosis factor-alpha monoclonal antibody in ophthalmologists, rheumatologists and immunologists.
RESUMO
Objective:To observe the effects of electroacupuncture(EA)on gut microbiota and serum inflammatory factors interleukin(IL)-1β and tumor necrosis factor(TNF)-α in Crohn disease(CD)model rats. Methods:Thirty-six Sprague-Dawley rats were randomly divided into a normal control(NC)group with 10 rats and a modeling group with 26 rats.In the modeling group,the CD rat model was prepared with 2,4,6-trinitrobenzene sulfonic acid(TNBS)enema.After successful modeling,the rats were randomly divided into a CD model(CD)group,an EA group,and a Western medicine(WM)group.The NC and CD groups received no treatment;the EA group was treated with EA for 20 min each time,with 7 consecutive days'intervention;the WM group received mesalazine enteric-coated tablet solution by gavage once a day for 7 d.The changes in body mass and disease activity index(DAI)were observed.Serum IL-1β and TNF-α were determined by enzyme-linked immunosorbent assay.Hematoxylin-eosin staining was used to observe the pathological changes of colon tissues,and 16S rDNA sequencing was used to analyze the structural changes of gut microbiota. Results:Compared with the NC group,the body mass of rats in the CD group decreased(P<0.01),and the DAI score increased(P<0.01);the colon tissue structure was disordered,and many inflammatory cells were present;also,IL-1β and TNF-α increased significantly(P<0.01).As a result,the diversity of gut microbiota decreased,and the abundance of some conditional pathogenic bacteria(such as Prevotella)increased,while the abundance of beneficial bacteria(such as Lactobacillus,Rochella,and Spirillum)decreased.After the intervention,compared with the CD group,the body mass of rats in the EA group and WM group increased(P<0.01);the DAI score decreased(P<0.01),the colon tissue structure improved,and the IL-1β and TNF-α levels decreased(P<0.01);the diversity of gut microbiota increased(P<0.05),and the abundance of some conditional pathogenic bacteria decreased while the abundance of beneficial bacteria increased in the EA group;whereas the diversity of gut microbiota in the WM group was not statistically different(P>0.05).

Objective To construct a stable synovial cell line MH7A from rheumatoid arthritis(RA)patients using lentiviral vectors that interfere with the expression of tumor necrosis factor receptor associated factor 2(TRAF2),and to study the role of TNF-α-TRAF2 signaling in MH7A abnormal proliferation.Methods Based on the design principles of human TRAF2 gene sequence and shRNA sequence,three pairs of TRAF2 shRNA interference se-quences were designed and synthesized.The primers were annealed by PCR,and a linear vector was obtained by double enzyme digestion PLKO.1-puro.The linearized vector was connected to the annealed primers through Solu-tion I,and the connected products were introduced into receptive cells.The plates were coated,and positive colo-nies were selected for sequencing.Three different recombinant plasmids of PLKO.1-TRAF2-shRNA lentivirus were constructed,and lentivirus packaging plasmids was used to package logarithmic growth phase HEK 293T cells.Vi-rus solution was collected to infect MH7A cells.At the same time,puromycin was used to screen MH7A stable transgenic strains with low TRAF2 expression.CCK-8 method,Western blot,and qPCR were used to detect the proliferation function of MH7A induced by TNF-α and low expression of TRAF2,as well as downstream signal TRAF2,P65 protein expression and mRNA levels.Results PLKO.1-TRAF2-shRNA(1),PLKO.1-TRAF2-shR-NA(2),and PLKO.1-TRAF2-shRNA(3)lentivirus vector plasmids and control group lentivirus vector plasmids PLKO.1-puro were successfully constructed.The three TRAF2-shRNA lentivirus vector plasmids and control group lentivirus vector plasmids PLKO.1-puro were respectively introduced into the lentivirus packaging plasmid of HEK 293T to obtain virus solution.After infecting MH7A cells with the virus solution,they were treated with puromycin(2.00 μ G/mL)screening and obtaining MH7A stable transgenic plants after 2 days.Through qPCR and Western blot results,it was found that the expression of TRAF2 mRNA and protein in PLKO.1-TRAF2-shRNA(1)MH7A stably transfected cells was significantly reduced compared to the negative control group.The results of CCK-8 and Western blot showed that after knocking down TRAF2 in MH7A,the proliferation of MH7A cells with low TRAF2 expression induced by TNF-α and the phosphorylation level of P65 were significantly reduced.Conclusion A sta-ble transgenic strain of PLKO.1-TRAF2-shRNA(1)MH7A cells was successfully constructed to investigate the role of TNF-α-TRAF2 signal activation in mediating abnormal proliferation of RA synovial cells.
RESUMO
Objective:To investigate the level change of cytokines in patients with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (EBV-HLH).Methods:A retrospective case control study was conducted. The clinical data of 65 patients with EBV-HLH, 30 patients with infectious mononucleosis (IM) (IM group) and 40 patients with non-EBV infection-associated hemophagocytic lymphohistiocytosis (non-EBV-HLH group) who admitted to Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology from February 2022 to February 2023 were retrospectively analyzed. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of the interleukin (IL)-6, IL-2, IL-10, IL-8, IL-1β, tumor necrosis factor-α (TNF-α) and interferon γ (IFN-γ) in serum samples of patients in the above 3 groups. The cytokines levels in EBV-HLH group were compared with those in IM group and non-EBV-HLH group, respectively.Results:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α and IFN-γ in EBV-HLH group were higher than those in the non-EBV-HLH group, and the differences were statistically significant (all P < 0.05). The cytokines levels of IL-2, IL-10 and IFN-γ in EBV-HLH group were higher than those in IM group, and the differences were statistically significant (all P < 0.05). Conclusions:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α, IFN-γ are increased in EBV-HLH patients, which may play an important role in the development and progression of EBV-HLH.
RESUMO
Objective To compare the effect of serratus anterior plane block(SAPB)and thoracic para-vertebral block(TPVB)on acute and chronic pain and plasma tumor necrosis factor-α(TNF-α)level after breast cancer modified radical operation.Methods A total of 99 patients with elective breast cancer modified radical operation,aged 35-70 years,American Society of Anesthesiologists physical status(ASA):grade Ⅰ-11,Body Mass Index(BMI):18-25 kg/m2,were randomly divided into three groups:the simple patient-con-trolled intravenous analgesia(PCIA)group(C group),PCIA combined with TPVB group(TC group)and PCI A combined witj SAPB group(SC group).TPVB and SAPB were performed before induction in the TC group and the SC group,and the relevant situation of regional blocking operation was recorded.The Visual Analogue Scales(VAS)scores in rest and activity at 2,4,8,12,24,48 h after operation,effective pressing times of analgesic pump and remedial analgesia situation after operation were recorded.The TNF-α levels be-fore anesthesia and at postoperative 12,48 h,in postoperative 3,6 months were measured by enzyme linked immunosorbent assay(ELISA).Results Compared with the TC group,the block operation time in the SC group was shorter(P＜0.05).Compared with the C group,the VAS scores in the state of rest and activity at postoperative 2,4,8,12,24 h in the TC group and SC group were significantly decreased(P＜0.05),and the dosage of remifentanil during operation,incidence rates of postoperative nausea and vomiting,effective press-ing times of analgesic pump and rate of remedial analgesia were all decreased(P＜0.05).There was no statis-tical difference in the incidence rate of post-mastectomy pain syndrome(PMPS)among the three groups(P＞0.05).Compared with the C group,the levels of plasma TNF-α in the TC group and SC group were decreased at postoperative 12,48 h,in postoperative 3,6 months,moreover the VAS score in the patients with PMPS was lower(P＜0.05).Compared with the patients without PMPS occurrence,the levels of plasma TNF-α in postoperative 3,6 months in the patients with PMPS were significantly up-regulated(P＜0.05).Conclusion By blocking the afference of pain signals caused by peripheral injury and reducing plasma TNF-α level,SAPB or TPVB may relieve the acute and chronic pain degree in the patients with breast cancer modified radi-cal operation.
