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.

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 evaluate the cost-effectiveness of adebrelimab combined with chemotherapy versus chemotherapy alone in the first-line treatment of extensive stage small cell lung cancer from Chinese healthcare system perspective.
METHODS
Using the data obtained from the CAPSTONE-1 trial(230 cases for adebrelimab group, and 232 cases for chemotherapy group), Markov model was created for simulation of the disease development process of the extensive stage small cell lung cancer. The total costs, quality-adjusted life-years(QALYs) and incremental cost-effectiveness ratio(ICER) in each group were calculated. The sensitivity of key parameters was analyzed.
RESULTS
Compared with pure chemotherapy(etoposide plus carboplatin chemotherapy), the ICER of adebrelimab combined with chemotherapy was 157128.79 yuan·QALY−1 under the situation of charity assistance, and 351367.27 yuan·QALY −1 in the environment of no charity assistance. Sensitivity analysis showed that the utility and the cost of adebrelimab were the main influence parameter.
CONCLUSION
Adebrelimab combined with chemotherapy regimen has no cost-effective advantage versus chemotherapy alone in the treatment of extensive stage small cell lung cancer under the current economic level of China; the probability of adebrelimab combined with chemotherapy being cost- effectiveness was 44.5% under the situation of charity assistan.

OBJECTIVE:
Clinical characteristics and outcome in COVID-19 with brucellosis patients has not been well demonstrated, we tried to analyze clinical outcome in local and literature COVID-19 cases with brucellosis before and after recovery.
METHODS:
We retrospectively collected hospitalization data of comorbid patients and prospectively followed up after discharge in Heilongjiang Infectious Disease Hospital from January 15, 2020 to April 29, 2022. Demographics, epidemiological, clinical symptoms, radiological and laboratory data, treatment medicines and outcomes, and follow up were analyzed, and findings of a systematic review were demonstrated.
RESULTS:
A total of four COVID-19 with brucellosis patients were included. One patient had active brucellosis before covid and 3 patients had nonactive brucellosis before brucellosis. The median age was 54.5 years, and all were males (100.0%). Two cases (50.0%) were moderate, and one was mild and asymptomatic, respectively. Three cases (75.0%) had at least one comorbidity (brucellosis excluded). All 4 patients were found in COVID-19 nucleic acid screening. Case C and D had only headache and fever on admission, respectively. Four cases were treated with Traditional Chinese medicine, western medicines for three cases, no adverse reaction occurred during hospitalization. All patients were cured and discharged. Moreover, one case (25.0%) had still active brucellosis without re-positive COVID-19, and other three cases (75.0%) have no symptoms of discomfort except one case fell fatigue and anxious during the follow-up period after recovery. Conducting the literature review, two similar cases have been reported in two case reports, and were both recovered, whereas, no data of follow up after recovery.
CONCLUSION
These cases indicate that COVID-19 patients with brucellosis had favorable outcome before and after recovery. More clinical studies should be conducted to confirm our findings.
