ObjectiveTo explore the effect of Buzhong Yiqitang on the immune imbalance of helper T cell 17 (Th17)/regulatory T cell (Treg) and Notch1 signaling pathway in mice with autoimmune thyroiditis (AIT). MethodA total of 60 8-week-old NOD.H-2h4 mice were randomly divided into the normal group, model group, western medicine group (selenium yeast tablet, 32.5 mg·kg-1), and low-dose (4.78 g·kg-1·d-1), middle-dose (9.56 g·kg-1·d-1), and high-dose (19 g·kg-1·d-1) Buzhong Yiqitang groups, with 10 mice in each group. The normal group was fed with distilled water, and the other groups were fed with water containing 0.05% sodium iodide for eight weeks. After the animal model of AIT was formed spontaneously, the mice were killed under anesthesia after intragastric administration for eight weeks. Serum anti-thyroglobulin antibodies (TGAb), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroid hormone (FT4) were detected by enzyme-linked immunosorbent assay (ELISA), and thyroid tissue changes were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expressions of retinoid-related orphan receptor-γt (RORγt), interleukin (IL)-17, forkhead box P3 (FoxP3), IL-10, Notch1, and hair division-related enhancer 1 (Hes1) in thyroid tissue were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultCompared with the normal group, the thyroid structure of the model group was severely damaged, and lymphocytes were infiltrated obviously. The levels of serum TGAb, FT3, and FT4 contents were significantly increased, and TSH content was significantly decreased (P<0.01). The mRNA and protein expression levels of RORγt, IL-17, Notch1, and Hes1 were significantly increased, while those of FoxP3 and IL10 were significantly decreased in the model group (P<0.01). Compared with the model group, thyroid structural damage and lymphocyte infiltration were improved in the treatment groups, and serum TGAb, FT3, and FT4 contents were significantly decreased. TSH content was increased, and mRNA and protein expression levels of RORγt, IL-17, Notch1, and Hes1 were decreased. mRNA and protein expression levels of FoxP3 and IL-10 were increased to different degrees (P<0.05, P<0.01), and the middle-dose Buzhong Yiqitang group had the most significant intervention effect. ConclusionBuzhong Yiqitang can alleviate the thyroid structural damage in AIT mice, and its mechanism may be related to improving the abnormal differentiation of Th17/Treg immune cells and inhibiting the activation of the Notch1 signaling pathway.

Objective:To investigate the influencing factors for early tumor recurrence and the efficacy of adjuvant chemotherapy in gallbladder carcinoma (GBC) patients after curative-intent resection.Methods:The retrospective case-control study was conducted. The clinicopathological data of 506 patients with GBC in 11 medical centers, including The First Affiliated Hospital of Xi'an Jiaotong University et al, from January 2016 to December 2020 were collected. There were 168 males and 338 females, aged (62±11)years. All patients underwent curative-intent resection of GBC, and they were divided into patients with and without early recurrence based on time to postoperative recurrence. Observation indicators: (1) treatment; (2) follow-up and survival of patients; (3) analysis of influencing factors for early tumor recurrence after curative-intent resection of GBC; (4) efficacy of postoperative adjuvant chemotherapy. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Mann-Whitney U test. Univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic regression model with forward method. The Kaplan-Meier method was used to draw survival curve and calculate survival rate, and Log-Rank test was used for survival analysis. Results:(1) Treatment. Of 506 patients, there were 112 cases with postoperative adjuvant chemotherapy, and 394 cases without postopera-tive adjuvant chemotherapy. They underwent 5(range, 3-9)cycles of postoperative adjuvant chemo-therapy. (2) Follow-up and survival of patients. All 506 patients underwent postoperative follow-up, with the follow-up time of 55(range, 34-93)months. During the follow-up, there were 248 patients with tumor recurrence, including 158 cases of early recurrence and 90 cases of late recurrence, and there were 258 patients without tumor recurrence. Of 506 patients, 275 cases survived, and 231 cases died of multiple organ failure caused by tumor recurrence and metastasis. The postoperative recurr-ence-free survival time, overall survival time were 52(range,1-93)months, 62(range, 2-93)months. The 1-, 3-, 5-year disease-free survival rates and 1-, 3-, 5-year overall survival rates of the 506 pati-ents were 68.8%, 53.8%, 47.9% and 78.3%, 58.7%, 51.6%, respectively. Results of survival analysis showed that the median overall survival time of 158 patients with postoperative early recurrence and 348 patients without postoperative early recurrence (including 90 cases of late recurrence and 258 cases of no tumor recurrence) were 9(range, 2-73)months and unreached, showing a significant difference between them ( χ2=456.15, P<0.05). (3) Analysis of influencing factors for early tumor recurrence after curative-intent resection of GBC. Results of multivariate analysis showed that carcinoembryonic antigen (CEA) >5.0 μg/L, poorly differentiated tumor, liver invasion, and tumor N staging as stage N1-N2 were independent risk factors influencing early tumor recurrence after cura-tive-intent resection of GBC ( odds ratio=2.74, 6.20, 1.81, 2.93, 4.82, 95% confidence interval as 1.62-4.64, 1.82-21.12, 1.15-3.08, 1.68-5.09, 1.91-12.18, P<0.05), while postoperative adjuvant chemo-therapy was an independent protect factor ( odds ratio=0.39, 95% confidence interval as 0.21-0.71, P<0.05). (4) Efficacy of postoperative adjuvant chemotherapy. The median overall survival time of 394 patients without postoperative adjuvant chemotherapy and 112 patients with postoperative adjuvant chemotherapy were 57(range, 2-93)months and unreached, showing a significant differ-ence between them ( χ2=9.38, P<0.05). Of the 158 patients with postoperative early recurrence after curative-intent resection of GBC, 135 cases didn't receive adjuvant chemotherapy and 23 cases received adjuvant chemotherapy, with the overall survival time of 8(range, 2-73)months and 17(range, 8-61)months, respectively, showing a significant difference between them ( χ2=7.68, P<0.05). Conclusions:CEA >5.0 μg/L, poorly differentiated tumor, liver invasion, and tumor N staging as stage N1-N2 are independent risk factors influencing early tumor recurrence after curative-intent resection of GBC, while postoperative adjuvant chemotherapy is an independent protect factor. Postoperative adjuvant chemotherapy can prolong the overall survival time of patients with post-operative tumor early recurrence.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4(TLR4)/nuclear transcription factor-kappa B(NF-κB)/absent in melanoma 2(AIM2)inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2h4 mice were selected and randomly divided into control group, model group, low, medium and high dose groups of Buzhong Yiqitang (4.78, 9.56, 19.12 g·kg-1), and western medicine group (selenium yeast tablets, 3.033×10-5 g·kg-1). The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model, and the control group drank ad libitum distilled water. Eight weeks later, the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye, and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA), and Real-time PCR was used to detect the expression of HMGB1, TLR4, AIM2, NF-κB p65,apoptosis-associated speck-like protein(ASC),cysteinyl aspartate-specific protease-1(Caspase-1), IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 (HMGB1), TLR4, AIM2, NF-κB p65, phosphorylation(p)-NF-κB p65, ASC, Caspase-1, and IL-1β proteins in thyroid tissue, and immunofluorescence staining was used to observe the protein expression of HMGB1, AIM2, and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group, the thyroid tissue of mice in the model group was significantly swollen, the spleen quality was significantly increased, and the expression of HMGB1, TLR4, NF-κB p65, AIM2, ASC, Caspase-1, IL-1β in thyroid tissue was significantly increased (P<0.01). Compared with the model group, the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved, the quality of spleen was significantly reduced, and the expression of HMGB1, TLR4, AIM2, NF-κB p65, p-NF-κB p65, ASC, Caspase-1, IL-1β in thyroid tissue was significantly reduced (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT, and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

Objective:To observe the efficacy of cosmetic suturing techniques combined with topical recombinant human basic fibroblast growth factor (rh-bFGF) in repairing facial trauma.Methods:A prospective study was conducted on 140 patients with facial trauma admitted to the Department of Burn and Plastic Surgery, Northern Jiangsu People's Hospital from January to December 2022. Patients were divided into two groups based on different treatment methods using a random number table method: treatment group (70 cases), including 38 males and 32 females aged 3 to 54 (23.1±8.2) years, received cosmetic suturing techniques combined with topical rh-bFGF for wound repair; control group (70 cases), including 36 males and 34 females aged 2 to 49 (22.3±7.5) years, only received cosmetic suturing techniques for wound repair. Patients were followed up 2 weeks post-surgery to evaluate wound healing quality. Patient satisfaction was assessed using the visual analogue scale (VAS). Six months post-surgery, scar conditions were evaluated using the Vancouver scar scale (VSS).Results:In the treatment group, 65 cases were directly sutured, and 5 cases were repaired with skin flaps, with a first-class healing rate of 100% (70/70). In the control group, 66 cases were directly sutured, and 4 cases were repaired with skin flaps, with a first-class healing rate of 91.4% (64/70). The first-class healing rate in the treatment group was higher than that in the control group, with a statistically significant difference ( P=0.037). Two weeks post-surgery, the VAS score for surgical satisfaction in the treatment group was (1.13±0.52) scores, which was lower than that in the control group (2.56±1.32) scores, with a statistically significant difference ( P<0.001). Six months post-surgery, the VSS score for the treatment group was (2.49±1.27) scores, which was lower than that in the control group (4.67±1.93) scores, with a statistically significant difference ( P<0.001). Conclusions:In repairing facial trauma, the combination of cosmetic suturing techniques and topical rh-bFGF can improve wound healing quality, reduce wound scarring, and enhance patient satisfaction with surgery.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

ObjectiveTo determine the influence of Buzhong Yiqitang on miRNA expression in thyroid tissues of mice with autoimmune thyroiditis (AIT). MethodThirty female 8-week-old NOD.H-2h4 mice were randomly assigned into normal control group, model group, and Buzhong Yiqitang group (BG), 10 in each group. Mice were subjected to a diet containing 0.05% sodium iodide for 8 weeks to build the AIT mouse model. After 8 weeks of administration (ig), samples were collected. A thyroid biopsy was performed on each group of mice, and differential miRNAs in thyroid tissues from each group of mice were analyzed based on experimental validation and bioinformatics. ResultCompared with the conditions of normal control group, thyroid lymphocytes had significant inflammatory infiltration, and there was an increase in serum TgAb level and interleukin(IL)-6 and IL-17 expression and a decrease in IL-1β expression in mice of the model group (P<0.05, P<0.01). In addition, 154 differentially expressed miRNAs were found. Compared with the conditions of model group, the degree of thyroid tissue inflammation was alleviated, and serum TgAb level, and IL-1β, IL-6 and IL-17 expression of mice treated with the Buzhong Yiqitang were reduced (P<0.05, P<0.01). Additionally, 112 differentially expressed miRNAs were identified in the BG group. Validation using real-time polymerase chain reaction(Real-time PCR) showed the same trend for miR-326-3p, miR-128-3p, miR-223-5p, miR-141-3p, miR-871-3p, and miR-204-3p as that obtained from miRNA sequencing. In particular, gene ontology(GO) functions were enriched for regulation of T cell activation, oxidative stress, and miRNA binding. Pathways identified by Kyoto encyclopedia of genes and genomes(KEGG)database tended to be enriched in phosphatidylinositol 3-kinases(PI3K)/protein kinase B(Akt), mitogen-activated protein kinase(MAPK), and cyclic adenosine monophosphate(cAMP) signaling pathways. Based on miRNA prediction differences, three key genes were identified: SMAD3, JAK2, and STAT3. ConclusionBushong Yiqitang might treat autoimmune thyroiditis by regulating 6 miRNAs.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.
