This article introduces Professor WU Weiping's experience in treating bronchiectasis based on the thought of "half treating from collaterals and half treating as abscess". Professor WU classified this disease under the category of "lung collaterals abscess" and proposed the general principle of "half treating from collaterals and half treating as the abscess"， based on the core pathogenesis of lung-spleen qi deficiency and phlegm-stasis heat accumulation. Treatment should be based on syndrome differentiation according to the pathological characteristics of the disease at different stages. During the acute exacerbation stage， when the lung qi depletion and phlegm-heat congestion obstruct the lung collaterals and form into lung abscess， the methods should therefore focus partly on resolving stasis and unblocking to treat from the collaterals， and partly on clearing heat， eliminating phlegm and draining pus to treat as the abscess. Modified Qianjin Xiejing Decoction （千金苇茎汤） and Loulu Lianqiao Decoction （漏芦连翘汤）. During the chronic protracted stage， when there is lung-spleen qi deficiency， along with collateral deficiency and latent abscess， the main focus should be half on regulating the middle jiao （焦）， moving qi and consolidating the exterior to treat from collaterals， and half on rectifying lung， dispelling stasis and resolving phlegm to treat as the abscess， with modified Yupingfeng Powder （玉屏风散） and Liujunzi Decoction （六君子汤）. At the same time， attention should be paid to differentiating phlegm， blood， and cough to tailor the prescription.

OBJECTIVE: To explore the research history, hotspots and development trends of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease（GERD）based on knowledge graph technology, and to provide references for clinical and basic research in this field. METHODS: The literature of acupuncture and moxibustion for gastroesophageal reflux disease was searched from the CNKI, Wanfang, VIP and SinoMed, from the establishment of the databases to December 31th, 2023. CiteSpace 6.2.R6 Advance was used to draw the knowledge graph of authors, institutions, keywords and other elements, and then perform the visual analysis. RESULTS: A total of 341 articles were included, with the number of publications showing an upward trend and the research types continually diversifying. A total of 832 authors and 308 institutions were analyzed, with XIE Sheng from the First Affiliated Hospital of Guangxi University of CM and BAI Xinghua from the Beijing University of CM as representative figures, forming core research teams. However, there was a lack of close collaboration between institutions, and no significant cross-regional research networks had been formed. A total of 192 keywords were included, forming 8 cluster labels, which mainly included 4 categories：treatment methods, disease types, TCM syndrome types, and literature types. The burst analysis showed that the methods of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease had gradually become more integrated, the treatment methods had transitioned from simple acupuncture therapy to combined therapies with proton pump inhibitors or TCM decoctions, the disease types had become more refined, the focus of mechanism research had shifted from lower esophageal sphincter pressure and esophageal motility to changes in gastrointestinal hormone levels, and the research hotspots had gradually shifted from improving clinical symptoms to considering both mental and psychological states. Twenty-three high-frequency acupoints were obtained, forming 8 clusters of "acupuncture techniques-acupoints" for the treatment of gastroesophageal reflux disease with acupuncture and moxibustion, indicating a gradual enrichment of acupuncture and acupoint treatment protocols. CONCLUSION The research on acupuncture and moxibustion in the treatment of gastroesophageal reflux disease has gradually deepened, in the future, the cooperation among research teams should be strengthened, the quality of clinical research should be improved, more multi-dimensional mechanism research and horizontal comparative research of different acupuncture and moxibustion methods should be made, to provide a basis for clinical promotion and deeper exploration.

Tooth pulpitis is a prevalent oral disorder. Understanding the underlying mechanisms of pulpitis and developing effective treatment strategies hold great significance. Ferroptosis has recently emerged as a new form of cell death, but the role of ferroptosis in pulpitis remains largely unknown. In our study, single-cell RNA sequencing (scRNA-seq) was used to identify cellular heterogeneity between 3 pulpitis tissue and 3 healthy pulp tissue, and explored ferroptosis occurrence in pulpitis tissue and inflamed dental pulp cells (DPCs). In scRNA-seq, 40 231 cells (Pulpitis: 17 814; Healthy pulp: 22 417) were captured, and visualized into 12 distinct cell clusters. Differentially expressed ferroptosis-related genes (DE-FRGs) were almost presented in each cluster in pulpitis vs healthy pulp. ROS and Fe²⁺ levels significantly rose, and immunohistochemistry showed low expression of GPX4 and high expression of PTGS2 in pulpitis. In LPS-stimulated DPCs, thymosin α1 increased the expression of GPX4 and FTL, and decreased expression of TNF-α, IL-1β, IL-6, and Fe²⁺ levels. In rat pulpitis models, both prothymosin α (PTMA, precursor of thymosin α1) gelatin sponge placed at the hole of pulp (LPS-P(gs)) and PTMA injection in pulp (LPS-P(i)) significantly reduced infiltration of inflammatory cells and expression of PTGS2, and increased the expression of GPX4. In RNA sequencing, the expression of DE-FRGs were reversed when thymosin α1 were added in LPS-stimulated DPCs. Collectively, single-cell atlas reveals cellular heterogeneity between pulpitis and healthy pulp, and ferroptosis occurrence in pulpitis. Thymosin α1 may reduce ferroptosis in DPCs to alleviate pulpitis and thus potentially has the ability to treat pulpitis.

Objective:To discuss the clinical efficacy and plausible mechanism of Tiao Yang Qu Xie(regulating Yang to eliminate pathogenic factors)needling method plus paroxetine in treating mild-to-moderate depression. Methods:Sixty-six patients with mild-to-moderate depression were divided into an observation group and a control group using the random number table method,each consisting of 33 cases.Another 25 healthy subjects were recruited as a healthy group.The control group took oral paroxetine tablets for treatment,and the observation group received additional acupuncture treatment 3 times weekly.Both groups underwent 4-week treatment.Before treatment,after 2-week and 4-week treatment,and 2 weeks after treatment(follow-up),the patients were assessed using the Hamilton depression scale-17-item(HAMD-17),self-rating depression scale(SDS),self-rating anxiety scale(SAS),and traditional Chinese medicine(TCM)pattern element identification scale for depression.The two groups each randomly contributed 25 cases to detect the protein content of brain-derived neurotrophic factor(BDNF)before treatment and after 4-week treatment,and compared with the healthy group. Results:After 2-week treatment,the markedly effective and total effective rates were significantly higher in the observation group than in the control group(P<0.05);after 4-week treatment,the observation group significantly surpassed the control group in comparing the markedly effective rate(P<0.05).After 2 and 4 weeks of treatment and at the follow-up,the HAMD-17 total score and sleep disorder factor score were lower in the observation group than in the control group(P<0.05);the anxiety-somatic score was lower in the observation group than in the control group after 2-week treatment(P<0.05).After 2 and 4 weeks of treatment and at the follow-up,the observation group was lower than the control group in comparing the scores of SDS,SAS,and TCM pattern element identification scale for depression(P<0.05).After 4-week treatment,the observation group had an increased serum BDNF protein content,higher than that in the control group(P<0.05)and had no significant difference compared to the healthy group(P>0.05). Conclusion:Compared to the use of oral paroxetine alone,acupuncture plus paroxetine can produce more significant efficacy in treating mild-to-moderate depression and act faster in improving sleep disorder and anxiety-somatic symptoms;increasing the serum BDNF protein content may be a part of the mechanism underlying its antidepressant actions.

【Objective】 To analyze the results of different methods for reactive samples screened by the enzyme linked immunosorbent assay (ELISA) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in blood donors. 【Methods】 From March to April 2020, a total of 8 632 blood samples in Shenzhen were screened for SARS-CoV-2 total antibodies (TAb, including IgG, IgM, IgA) in plasma using ELISA(PC group), the antibody reactivity samples and their follow up plasma samples (FC group), and samples of disease control group(DC group) from January to April 2020 were detected using the following methods: 1) ELISA method for detecting IgG, IgM, and (or without detection) TAb; 2) pseudovirus neutralizing antibody test(pVNT); 3) western blot (WB) of SARS-CoV-2 antibody. The negative control group(NC group) from February to April 2020 performed ELISA and WB testing. 【Results】 Among the 34 total antibody positive samples, 2 were positive for pVNT test, and the total antibody, IgG and WB in the initial screening and tracking testing were positive. Thereafter, it was determined to be confirmed positive. The other 2 cases were positive for pVNT test, while the samples with positive WB results were in the follow-up stage. The TAb, IgG, and pVNT results did not conform to the dynamic evolution of antibodies, and cannot be determined as confirmed positive. 【Conclusion】 The infection status of antibody reactivity samples screened by SARS-CoV-2 ELISA can be judged by the logic of pVNT, WB and the dynamic change of antibody.
