Objective:To discuss the effect of Jiegeng Yuanshen Tang(JGYST)on airway tissue inflammation and mucus secretion in the mice with allergic asthma,and to clarify the related mechanism.Methods:Forty male C57BL/J mice were randomly divided into control group,JGYST group,ovalbumin(OVA)group,and OVA + JGYST group.The mice in OVA group and OVA +JGYST group were sensitized with 50 μg OVA via intraperitoneal injection twice weekly,followed by 20 μg OVA nasal drops daily for 7 d to induce asthma;the mice in OVA +JGYST group were gavaged with 200 μL JGYST 1 h before each OVA challenge,and the administration lasted for 7 d;the mice in control group were given equivalent dose of PBS via intraperitoneal injection,nasal drops,and gavage;the mice in JGYST group were given the same dose of PBS for intraperitoneal and nasal administration and gavaged with the same dose of JGYST.The pathomorphology of lung tissue of the mice in various groups was observed by HE staining and periodic acid-Schiff(PAS)staining,and the inflammation and PAS scores were calculated;flow cytometry method was used to detect the numbers of eosinophils,neutrophils,helper T lymphocyte 1(Th1)cells,helper T lymphocyte 2(Th2)cells,and dendritic cells(DCs),as well as the percentage of mature DCs and level of reactive oxygen species(ROS)in lung tissue of the mice in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of interleukin-4(IL-4),interleukin-10(IL-10),and tumor necrosis factor-α(TNF-α)mRNA in lung tissue of the mice in various groups.Results:The HE and PAS staining results showed that the mice in control group had intact airway and alveolar structure,without infiltration of inflammatory cells or mucus secretion;compared with control group,there was a large number of infiltrating inflammatory cells in airway tissue of the mice in OVA group,and the inflammation and PAS scores were increased(P<0.01);compared with OVA group,the infiltration of inflammatory cells in airway tissue of the mice in JGYST group and OVA + JGYST group was decreased,and the inflammation and PAS scores were significantly decreased(P<0.01).The flow cytometry results showed that compared with control group,the numbers of eosinophils,Th2 cells,and DCs in lung tissue of the mice in OVA group were increased(P<0.05 or P<0.01),and the percentage of mature DCs and level of ROS were significantly increased(P<0.01);compared with OVA group,the numbers of eosinophils,Th2 cells,and DCs in lung tissue of the mice in JGYST group and OVA + JGYST group were decreased(P<0.01),and the percentage of mature DCs and level of ROS were significantly decreased(P<0.01).The RT-qPCR results showed that compared with control group,the expression levels of IL-4,IL-10,and TNF-α mRNA in lung tissue of the mice in OVA group were increased(P<0.01);compared with OVA group,the expression levels of IL-4 and TNF-α mRNA in lung tissue of the mice in JGYST group and OVA + JGYST group were decreased(P<0.01),while the expression level of IL-10 mRNA was increased(P<0.01).Conclusion:JGYST can alleviate the airway tissue inflammation and mucus secretion in the mice with allergic asthma,and its mechanism may be related to reducing the number of Th2 cells and DCs,decreasing the ROS level and expression level of proinflammatory cytokine,and increasing the expression level of anti-inflammatory cytokine.

Objective:To investigate the incidence and risk factors of ultrafiltration failure (UFF) in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).Methods:The clinical data of 65 patients undergoing CAPD at the Hubei Provincial Corps Hospital of Chinese People's Armed Police Forces and the General Hospital of Central Theater Command from January 2016 to December 2021 were retrospectively analyzed. The clinical data included patient history, smoking history, duration of peritoneal dialysis, incidence of peritonitis, levels of hemoglobin, albumin, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, and triglyceride. Univariate and multivariate regression analyses were conducted to investigate the correlation between UFF and various indicators in patients undergoing CAPD.Results:Among the 65 patients undergoing CAPD, the incidence of UFF was 35.4% (23/65). There were significant differences in duration of peritoneal dialysis, history of peritonitis, history of type 2 diabetes mellitus, serum albumin, low-density lipoprotein cholesterol, and triglyceride between patients with UFF and those without UFF ( t = -5.05, χ2 = 11.51, 6.83, t = 5.91, -3.28, -2.83, all P < 0.05). Multivariate regression analysis showed that albumin was negatively correlated with UFF ( r = -1.06, P < 0.05), while duration of peritoneal dialysis, level of low-density lipoprotein cholesterol, and peritonitis were positively correlated with UFF ( r = 0.43, 2.20, 1.67, all P < 0.05). Conclusion:Peritoneal dialysis duration, peritonitis, and low-density lipoprotein cholesterol are risk factors for UFF in patients undergoing CAPD, while albumin is a protective factor against UFF in these patients.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective:To investigate the detection of bone marrow tumor cells in small cell lung cancer (SCLC) patients and their relationship with clinical features, treatment response and prognosis.Methods:A total of 113patients with newly diagnosed SCLC from January 2018 to October 2022 at Beijing Chest Hospital were prospectively enrolled. Before treatment, bone marrow was aspirated and separately submitted for tumor cells detection by liquid-based cytology and disseminated tumor cells (DTCs) detection by the substrction enrichment and immunostaining fluorescence in situ hybridization (SE-iFISH) platform. The correlation between the detection results of the two methods with patients' clinical features and treatment response was evaluated by Chi-square. Kaplan-Meier method was applied to create survival curves and the Cox regression model was used for multivariate analysis.Results:The positive rate of bone marrow liquid-based cytology in SCLC was 15.93% (18/113). The liver and bone metastases rates were significantly higher (55.56% vs 11.58% for liver metastasis, P＜0.001; 77.78% vs 16.84% for bone metastasis, P＜0.001) and thrombocytopenia was more common (16.67% vs 2.11%, P=0.033) in patients with tumor cells detected in liquid-based cytology than those without detected tumor cells. As for SE-iFISH, DTCs were detected in 92.92% of patients (105/113), the liver and bone metastasis rates were significantly higher (37.93% vs 11.90% for liver metastasis, P=0.002; 44.83% vs 20.23 % for bone metastasis, P=0.010), and the incidence of thrombocytopenia was significantly increased (13.79% vs 1.19%, P=0.020) in patients with DTCs≥111 per 3 ml than those with DTCs＜111 per 3 ml. The positive rates of bone marrow liquid-based cytology in the disease control group and the disease progression group were 12.00% (12/100) and 46.15% (6/13), respectively, and the difference was statistically significant ( P=0.002). However, the result of SE-iFISH revealed the DTCs quantities of the above two groups were 29 (8,110) and 64 (15,257) per 3 ml, and there was no statistical difference between the two groups ( P=0.329). Univariate analysis depicted that the median progression-free survival (PFS) and median overall survival (OS) of liquid-based cytology positive patients were significantly shorter than those of tumor cell negative patients (6.33 months vs 9.27 months for PFS, P=0.019; 8.03 months vs 19.50 months for OS, P=0.019, P=0.033). The median PFS and median OS in patients with DTCs≥111 per 3 ml decreased significantly than those with DTCs＜111 per 3 ml (6.83 months vs 9.50 months for PFS, P=0.004; 11.2 months vs 20.60 months for OS, P=0.019). Multivariate analysis showed that disease stage ( HR=2.806, 95% CI:1.499-5.251, P=0.001) and DTCs quantity detected by SE-iFISH ( HR=1.841, 95% CI:1.095-3.095, P=0.021) were independent factors of PFS, while disease stage was the independent factor of OS ( HR=2.538, 95% CI:1.169-5.512, P=0.019). Conclusions:Both bone marrow liquid-based cytology and SE-iFISH are clinically feasible. The positive detection of liquid-based cytology or DTCs≥111 per 3 ml was correlated with distant metastasis, and DTCs≥111 per 3 ml was an independent prognostic factor of decreased PFS in SCLC.

Objective To analyze the chemical components of Xiaoshi Lidan pills by using UPLC-MS/MS and explore the mechanism of Xiaoshi Lidan pills in the treatment of cholelithiasis through network pharmacology and molecular docking techniques.Methods The pharmacologically active components of Xiaoshi Lidan pills were analyzed through UPLC-MS/MS and compared with standard references.Potential targets of these components were obtained by searching the TCMSP and ETCM databases,and disease-related targets for cholelithiasis were identified using the DisGeNET database.The overlapping targets were used to construct a protein-protein interaction(PPI)network in the String database,and a"drug-component-target"network was built using Cytoscape 3.9.1.GO and KEGG enrichment analyses were performed for the core targets.Finally,the top 5 compounds with strong activity were selected as ligands for molecular docking with the screened disease target genes.The anti-inflammatory activity was verified by RAW264.7 cells,and the mRNA expression of TNF-a and other inflammatory factors was detected by RT-PCR.Results UPLC-MS/MS identified 30 compounds in Xiaoshi Lidan pills,among which baicalin,quercetin,wogonin,baicalein-7-O-glucuronide,and emodin were identified as key components of Xiaoshi Lidan pills.Network pharmacology identified 107 targets associated with cholelithiasis,with Alb,TP53,ESR1,TNF,and INS identified as core targets.GO analysis indicated the involvement in inflammation response and steroid binding,while KEGG pathways were primarily related to lipid metabolism,atherosclerosis,and the TNF signaling pathway.Molecular docking analysis and anti-inflammatory screening in vitro showed that Xiaoshi Lidan pills exhibited certain anti-inflammatory activity by regulating inflammatory factors such as TNF and inhibiting NO production through baicalein,quercetin,emodin and other components.Conclusion Xiaoshi Lidan pills exerts its therapeutic effect on cholelithiasis by regulating TNF-related pathways through components such as baicalin,thereby inhibiting the inflammatory response.

Objective:To analyze the factors affecting delayed chemotherapy in children with Burkitt lymphoma (BL) and their influence on prognosis.Methods:Retrospective cohort study. Clinical data of 591 children aged ≤18 years with BL from May 2017 to December 2022 in China Net Childhood Lymphoma (CNCL) was collected. The patients were treated according to the protocol CNCL-BL-2017. According to the clinical characteristics, therapeutic regimen was divided into group A, group B and group C .Based on whether the total chemotherapy time was delayed, patients were divided into two groups: the delayed chemotherapy group and the non-delayed chemotherapy group. Based on the total delayed time of chemotherapy, patients in group C were divided into non-delayed chemotherapy group, 1-7 days delayed group and more than 7 days delayed group. Relationships between delayed chemotherapy and gender, age, tumor lysis syndrome before chemotherapy, bone marrow involvement, disease group (B/C group), serum lactate dehydrogenase (LDH) > 4 times than normal, grade Ⅲ-Ⅳ myelosuppression after chemotherapy, minimal residual disease in the interim assessment, and severe infection (including severe pneumonia, sepsis, meningitis, chickenpox, etc.) were analyzed. Logistic analysis was used to identify the relevant factors. Kaplan-Meier method was used to analyze the patients' survival information. Log-Rank was used for comparison between groups.Results:Among 591 patients, 504 were males and 87 were females, the follow-up time was 34.8 (18.6,50.1) months. The 3-year overall survival (OS) rate was (92.5±1.1)%,and the 3-year event-free survival (EFS) rate was (90.5±1.2)%. Seventy-three (12.4%) patients were in delayed chemotherapy group and 518 (87.6%) patients were in non-delayed chemotherapy group. The reasons for chemotherapy delay included 72 cases (98.6%) of severe infection, 65 cases (89.0%) of bone marrow suppression, 35 cases (47.9%) of organ dysfunction, 22 cases (30.1%) of tumor lysis syndrome,etc. There were 7 cases of chemotherapy delay in group B, which were seen in COPADM (vincristine+cyclophosphamide+prednisone+daunorubicin+methotrexate+intrathecal injection,4 cases) and CYM (methotrexate+cytarabine+intrathecal injection,3 cases) stages. There were 66 cases of chemotherapy delay in group C, which were common in COPADM (28 cases) and CYVE 1 (low dose cytarabine+high dose cytarabine+etoposide+methotrexate, 12 cases) stages. Multinomial Logistic regression analysis showed that the age over 10 years old ( OR=0.54,95% CI 0.30-0.93), tumor lysis syndrome before chemotherapy ( OR=0.48,95% CI 0.27-0.84) and grade Ⅲ-Ⅳ myelosuppression after chemotherapy ( OR=0.55,95% CI 0.33-0.91)were independent risk factors for chemotherapy delay.The 3-year OS rate and the 3-year EFS rate of children with Burkitt lymphoma in the delayed chemotherapy group were lower than those in the non-delayed chemotherapy group ((79.4±4.9)% vs. (94.2±1.1)%, (80.2±4.8)% vs. (92.0±1.2)%,both P<0.05). The 3-year OS rate of the group C with chemotherapy delay >7 days (42 cases) was lower than that of the group with chemotherapy delay of 1-7 days (22 cases) and the non-delay group (399 cases) ((76.7±6.9)% vs. (81.8±8.2)% vs. (92.7±1.3)%, P=0.002).The 3-year OS rate of the chemotherapy delay group (9 cases) in the COP (vincristine+cyclophosphamide+prednisone) phase was lower than that of the non-chemotherapy delay group (454 cases) ((66.7±15.7)% vs. (91.3±1.4)%, P=0.005). Similarly, the 3-year OS rate of the chemotherapy delay group (11 cases) in the COPADM1 phase was lower than that of the non-chemotherapy delay group (452 cases) ((63.6±14.5)% vs. (91.5±1.3)%, P=0.001). Conclusions:The delayed chemotherapy was related to the age over 10 years old, tumor lysis syndrome before chemotherapy and grade Ⅲ-Ⅳ myelosuppression after chemotherapy in pediatric BL. There is a significant relationship between delayed chemotherapy and prognosis of BL in children.

Objective:To explore the longitudinal changes of symptom clusters and quality of life in young and middle-aged postoperative patients with cervical cancer during chemotherapy, and to clarify the correlation between the two, in order to provide reference for clinical staff symptom management and improvement of patients′ quality of life.Methods:A longitudinal study was conducted, a total of 252 young and middle-aged who underwent chemotherapy after radical cervical cancer surgery in the gynecological ward of Henan Provincial People′s Hospital from December 2022 to August 2023 were selected as the investigation objects by convenient sampling method. Data were collected at 2 d before chemotherapy (T1), 1 week after the first chemotherapy (T2), 1 week after the third chemotherapy (T3), and 1 week after the sixth chemotherapy (T4), using the general data questionnaire, the Chinese version of the Memorial Symptom Assessment Scale and the Functional Assessment of Cancer Therapy-Cervix. Exploratory factor analysis was used to extract symptom clusters from the data. The generalized estimation equation model was used to analyze the dynamic change trend and correlation between symptom clusters and quality of life.Results:A total of 221 patients with cervical cancer aged 18-59 (46.85 ± 6.50) years old were included. At T1 and T2, there were 4 symptom clusters, which were psychological symptom cluster, gastrointestinal symptom cluster, disease behavior symptom cluster and perimenopausal symptom cluster. T3 and T4 increased the neurological symptom cluster and self-image disorder symptom cluster, a total of 6 symptom clusters. The higher score of each symptom cluster, the lower total score of quality of life (Wald χ2 values were 8.08-62.70, all P<0.01). Conclusions:Young and middle-aged postoperative patients with cervical cancer suffered from multiple symptom clusters during chemotherapy, which not only remained relatively stable, but also showed a constantly changing trend. Effective dynamic management of symptoms clusters in young and middle-aged postoperative patients with cervical cancer during chemotherapy is expected to improve their quality of life.

Objective:To explore the application value of real-time shear wave elastography(SWE)and ultrafast pulse wave velocity(UFPWV)techniques in assessing carotid artery stiffness of patients with gouty arthritis(GA).Methods:A total of 80 GA patients admitted to the First People's Hospital of Yibin from August 2022 to July 2023 were selected as GA group.Among of them,24 cases combined with bone erosion who were confirmed by imaging examination,and 56 cases did not combine with bone erosion.In addition,a total of 40 healthy individuals,who underwent physical examinations in our hospital during the same period,were selected as the healthy control group.SWE and UFPWV were used to detect the maximum,minimum and mean values of Young's modulus values of the vessel wall of common carotid artery,and the pulse wave velocity at the beginning of systole(PWVBS)and pulse wave velocity at the end of systole(PWVES)of the vessel wall of common carotid artery of all subjects,and to assess the hardness of circumferential and longitudinal vessel wall of common carotid artery of them.The differences in Young's modulus values,PWVBS and PWVES between two groups were compared.And then,the correlations between bone erosion and Young's modulus values,PWVBS,PWVES of GA patients were further analyzed.Results:The maximum,minimum,mean values,PWVBS and PWVES in the GA group were respectively(78.80±12.38)kPa,(57.83±7.42)kPa,(67.67±8.38)kPa,(7.06±0.59)m/s and(9.50±0.63)m/s,which were significantly higher than those in the healthy control group(t=11.066,8.216,11.751,14.159,19.118,P＜0.05).The maximum,minimum,mean values,PWVBS and PWVES of GA patients with bone erosion were respectively(82.95±6.37)kPa,(59.59±5.29)kPa,(72.18±7.62)kPa,(7.37±0.43)m/s,(10.43±0.47)m/s,which were significantly higher than those[(77.01±5.32)kPa,(57.08±4.73)kPa,(65.73±4.54)kPa,(6.92±0.39)m/s and(9.10±0.41)m/s]of GA patients without bone erosion,the differences were significant(t=4.309,2.099,4.699,4.586,12.720,P＜0.05).Spearman correlation analysis showed that there was significant correlations between maximum,minimum,mean values,PWVBS,PWVES and the combined bone erosion in GA patients(r=0.602,0.421,0.682,0.647,0.732,P＜0.05).Conclusion:SWE and UFPEV techniques can evaluate the hardness of vascular wall of GA patients,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient is higher than that of healthy person,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient with bone erosion is higher.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
