OBJECTIVE To investigate the effects of galangin on rheumatoid arthritis （RA） in rats by regulating the Janus kinase 3 （JAK3）/signal transducer and activator of transcription 3 （STAT3） pathway. METHODS Fifty male SD rats were taken， and an emulsion composed of bovine type Ⅱ collagen and Freund’s complete adjuvant was injected subcutaneously to establish an induced arthritis model. The rats that were successfully modeled were randomly divided into model group， low， medium and high dose groups of galangin （1， 5， 15 mg/kg）， and methotrexate group （positive control， 2 mg/kg）， with 10 rats in each group. Another 10 normal rats were taken as the normal group. Starting from the 15th day of modeling， each group of rats was gavaged with the corresponding drug solution or normal saline containing 0.5% Tween 80 once a day for 28 consecutive days. The arthritis index （AI） scores and paw volume of rats were compared before and after gavage administration. Twenty-four hours after the last administration， the serum levels of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， IL-4 and IL-10 were determined， the pathological changes in ankle joint synovial tissue were observed， and the protein expressions of UNC-51 like kinase 1 （ULK1）， Beclin-1， microtubule-associated protein 1 light chain 3 （LC3）， B cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， caspase-3， JAK3， phosphorylated JAK3 （p-JAK3）， STAT3 and phosphorylated STAT3 （p-STAT3） in the synovial tissue of the ankle joint were detected， as well as the fluorescence intensity of LC3-positive areas. RESULTS Compared with the model group， the pathological changes such as cellular proliferation of ankle joint synovial tissue and infiltration of inflammatory cells in rats of each administration group showed improvement. Moreover， their AI scores and paw pad volumes （on day 28 after gavage）， the levels of IL-6 and TNF-α， the protein expression of Bcl-2， and the phosphorylation levels of JAK3 and STAT3 were all significantly reduced （ P ＜0.05）. The levels of IL-4 and IL-10， the protein expressions of ULK1， Beclin-1， Bax， caspase-3 and LC3， as well as the fluorescence intensity of LC3-positive areas， were all significantly increased （ P ＜0.05）. Moreover， the effect of galangin was in a dose-dependent manner （ P ＜0.05）. CONCLUSIONS Galangin can induce sustained autophagy in synovial tissue cells of RA rats， promote cell apoptosis， inhibit synovial cell proliferation， and alleviate persistent inflammatory responses. The above anti-RA effects may be related to the inhibition of the JAK3/STAT3 pathway.

Hemodynamic monitoring in shock is one of the core challenges in sepsis management.This article systematically explores how to optimize hemodynamic management in septic shock from three perspectives:assessment of fluid responsiveness and tolerance,monitoring of arterial and venous blood pressure,and macro- and microcirculatory monitoring.Firstly,fluid responsiveness assessment is the foundation of fluid therapy,but it must be combined with fluid tolerance to avoid fluid overload.Secondly,the refined evaluation of arterial and venous pressure changes,from macrocirculation to microcirculation,provides a more comprehensive perspective for hemodynamic management.Thirdly,the transition from cardiac output to microcirculatory flow is critical for optimizing oxygen delivery,requiring dynamic adjustment of treatment through both invasive and non-invasive techniques,while also considering the relationship between cardiac output and oxygen delivery and their impact on tissue oxygenation.By integrating these monitoring approaches,individualized and precise treatment for septic shock patients can be achieved,thereby improving outcomes.

Objective:To explore the effectiveness and safety of different anticoagulation strategies during continuous blood purification (CBP) treatment,providing a reference for anticoagulation strategies in critically ill children undergoing CBP.Methods:A retrospective study was conducted,including children admitted to the PICU of Children's Hospital of Fudan University from January 2019 to December 2024.According to the anticoagulation methods used during CBP treatment,patients were divided into the sodium citrate group and the heparin group.CBP was performed using continuous venovenous hemofiltration or continuous venovenous hemodialysis filtration mode,with a blood flow rate of 3-5 mL/(kg·min),replacement fluid rate of 30-50 mL/(kg·h),and dialysis fluid rate of 20-30 mL/(kg·h).The filter lifespan,28-day all-cause mortality,total length of hospital stay,PICU stay duration,adverse events,and associated costs were compared between the two groups.Results:A total of 221 children were included (105 in the sodium citrate group and 116 in the heparin group),with a cumulative use of 666 filters (284 in the sodium citrate group and 382 in the heparin group).(1) There were no statistically significant differences in general data,including age,sex ratio,underlying diseases,the ratio and duration of invasive mechanical ventilation,vasopressor scores at baseline,and indications for CBP between the two groups (all P>0.05).(2) The filter lifespan was 20(14,32) hours for the sodium citrate group and 21(13,35) hours for the heparin group,with no statistically significant difference between the two groups ( P>0.05); the proportion of accidental downstroke was 2.8% and 6.5%,respectively,with a statistically significant difference ( P=0.029); among the 221 children,86 died,with 38 deaths (35.2%) in the sodium citrate group and 49 deaths (38.9%) in the heparin group,showing no statistically significant difference.(3) The sodium citrate group had a higher incidence of metabolic alkalosis,hypocalcemia,and sodium citrate accumulation (44.4% vs. 1.6%,32.7% vs 9.4%,7.7% vs 0,all P<0.01); the heparin group had a greater proportion of bleeding (6.0% vs. 2.9%) and was more likely to develop heparin-induced thrombocytopenia (10.2% vs. 0, P<0.01).(4) The total hospitalization costs for the sodium citrate group were significantly higher than for the heparin group (200 327 yuan vs. 152 077 yuan, P=0.05); costs related to the use of anticoagulants and monitoring indicators during CBP treatment were also higher in the sodium citrate group (2 479 yuan vs. 682 yuan, P<0.01). Conclusions:Sodium citrate is a safe and effective anticoagulation method for critically ill children undergoing CBP,which can reduce the risk of filter clotting compared to systemic heparin anticoagulation.

Objective To investigate the predictive value of uric acid for cardiovascular events in the elderly patients with ACS.Methods An observational follow-up study was conducted on 3440 ACS inpatients and outpatients admitted in the Heart Center of Beijing Chaoyang Hospital and the First Medical Center of Chinese PLA General Hospital from June 2017 to October 2022.According to the occurrence of cardiovascular events,they were divided into a cardiovascular event group(529 patients)and a non-cardiovascular event group(2911 patients).Their clinical data were collected for Cox risk proportional regression analysis.Results The cardiovascular event group had significantly uric acid when compared with the non-cardiovascular event group(P＜0.01).Af-ter adjusting the traditional risk factors and plasma biomarkers,uric acid was still a significant predictor for clinical endpoints(HR=2.634,95％CI:1.870-3.744,P＜0.01)and for cardiovascu-lar events(HR=1.508,95％CI:1.357-1.660,P＜0.01).Furthermore,uric acid was significantly correlated with acute heart failure,cardiovascular death and all-cause death(P＜0.01).Conclusion Uric acid is a risk predictor for cardiovascular events in elderly ACS patients,and can provide ear-ly warning information and diagnostic value for acute cardiovascular events.

The risk and incidence of malnutrition among patients with inflammatory bowel disease(IBD)are significantly higher than those in the general population,which affect the therapeutic efficacy and prognosis of patients.Clinical nutrition plays an important role in the treatment of IBD,and with the fact that there have been many studies on the clinical practice of nutrition therapy in IBD both domestically and abroad in recent years,it is necessary to update the expert consensus on nutrition therapy for IBD and provide the latest guidance for clinical practice.This consensus is drafted and revised by experts from Inflammatory Bowel Disease Group of Chinese Society of Gastroenterology,Gastroenterology and Nutrition Cooperative Group of Chinese Society of Parenteral and Enteral Nutrition,and Nutrition Support and Treatment Collaboration Group of Chinese Society of Gastroenterology,Chinese Medical Association.It combines both expert consensus abroad and Chinese expert consensus on nutrition support therapy in inflammatory bowel disease(the second edition),aiming to reflect the latest concepts and research progress,and provide standardized guidance for nutrition therapy of IBD.In order to be consistent with the professional terminology adopted by international authoritative nutrition academic organizations,especially considering the unique role of clinical nutrition in the treatment of IBD,this consensus is hereby renamed as Expert consensus on nutrition therapy for inflammatory bowel disease.

BACKGROUND:The Ilizarov technique is very effective in the treatment of congenital brachymetatarsia of the fourth,but there are still some complications.The optimal proportion of lengthening of the fourth metatarsal is still controversial.OBJECTIVE:To explore the clinical efficacy of Ilizarov technique in the treatment of congenital brachymetatarsia of the fourth and the optimal lengthening ratio.METHODS:Medical records of patients with congenital brachymetatarsia of the fourth treated with Ilizarov technique in Guangdong Provincial Hospital of Traditional Chinese Medicine from August 2021 to October 2023 were collected.American Orthopaedic Foot and Ankle Society scores before and after the treatment,length of the fourth metatarsal before and after surgery,and postoperative complications were evaluated.The prolongation ratio was analyzed by subgroups to assess the best suitable length for the operative conditions.RESULTS AND CONCLUSION:(1)A total of 16 patients were included.The length of the fourth metatarsal before treatment was(43.51±3.75)mm,and the shortening length was(12.53±2.82)mm;the lengthening time during the treatment period was(36.95±4.12)days,and the time with external fixation bracket was(102.30±32.74)days,and the lengthening length after the treatment was(13.90±3.47)mm,and the prolongation ratio was(32.30±9.10)％.(2)American Orthopaedic Foot and Ankle Society scores were significantly increased at the last follow-up compared with that before treatment(t=0.763,P＜0.01).(3)The main postoperative complications were bone nonunion,metatarsophalangeal joint dislocation,metatarsophalangeal joint narrowing,and excessive lengthening of the fourth metatarsal.All patients were free of infection and abnormal sensation in the toe.(4)Subgroup analysis based on prolongation ratio showed that the rate of complications in patients in the prolongation ratio ≤ 35.36％group(17％)was significantly lower than the prolongation ratio＞35.36％group(100％)(t=14.008,P＜0.01).Meanwhile,the postoperative American Orthopaedic Foot and Ankle Society score of patients in the prolongation ratio ≤ 35.36％group(90.25±3.01)was higher than that of patients in the prolongation ratio＞35.36％group(82.00±9.97)(t=2.254,P=0.037).(5)It is concluded that Ilizarov technique for the treatment of congenital brachymetatarsia of the fourth is less traumatic surgery,can significantly improve the foot deformity of patients,especially suitable for the treatment of patients whose prolongation ratio does not exceed 35.36％,with low complication rate and satisfactory results.

Objective To evaluate the efficacy,safety and patient compliance of a quadruple therapy containing minocycline compared with the traditional quadruple therapy in the treatment of Helicobacter(H.)pylori.Methods This study included 200 H.pylori positive patients,with 100 assigned to the minocycline-containing bismuth quadruple therapy group(LBMC group)and the other 100 to the amoxicillin-containing bismuth quadruple therapy group(LBAC group).After matching the two groups of patients using the propensity score matching(PSM)method,there were 86 cases in each group.Telephone follow-up was conducted on the 14th day after the start of treatment to record patient medication compliance and adverse drug reactions.A 13C urea breath test was performed for re-examination at least one month after completing the treatment plan and discontinuing medication.The intention-to-treat(ITT)and per-protocol(PP)analyses were used to compare the H.pylori eradication rates between the two groups,and Chi-square test and t-test were used for intergroup comparison.Results In the ITT analysis,the eradication rates of the LBMC group and the LBAC group were 89.5%(77/86,95%CI:82.9%～96.1%)and 82.6%(71/86,95%CI:74.4%～90.7%),respectively.In the PP analysis,the eradication rates were 92.6%(75/81,95%CI:86.8%～98.4%)and 88.8%(71/80,95%CI:81.7%～95.8%),respectively.The adverse reaction rate of the LBMC group was 27.9%(24/86),and that of the LBAC group 31.4%(27/86),showing no statistically significant difference(P>0.05).In terms of compliance,the LBMC group was 94.2%(81/86),and the LBAC group 93.0%(80/86),revealing no statistically significant difference(P>0.05).Conclusion As a first-line treatment for eradicating H.pylori,regimens containing minocycline demonstrate equivalent eradication rates to those containing amoxicillin,with similar safety and compliance.They can be used as an alternative treatment for patients allergic to penicillin.

Conclusions:Sodium citrate is a safe and effective anticoagulation method for critically ill children undergoing CBP,which can reduce the risk of filter clotting compared to systemic heparin anticoagulation.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.
