One of the major toxic effects of exposure to ammonia is the resulting pulmonary acute and chronic effects. This study investigated the acute pulmonary effects of exposure to ammonia lower than the recommended threshold limit value (TLV). This cross-sectional study was conducted in 2021 in four chemical fertilizer production industries using ammonia as the main raw material. A total of 116 workers who were exposed to ammonia were investigated. The level of exposure to ammonia was measured by NMAM 6016, and the evaluation of pulmonary symptoms and function parameters was done using the American Thoracic Society and European Respiratory Society protocols in four sessions. The paired-sample t-test, repeated measures test, Chi-square, and Fisher's exact test were run to analyze the collected data. The prevalence rates of pulmonary symptoms, including cough, dyspnea, phlegm, and wheezing, were 24.14, 17.24, 14.66, and 16.38%, respectively, after one exposure shift. It was observed that all pulmonary function parameters were reduced after one exposure shift to ammonia. The results revealed that the parameters of vital capacity, forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), the FEV1/FVC ratio, and peak expiratory flow significantly decreased ( < 0.05) across four exposure shifts. The findings indicated that exposure to ammonia at concentrations lower than one-fifth of TLV could bring about acute pulmonary effects and reduce pulmonary function parameters, similar to the pattern observed in obstructive pulmonary diseases.

This study aims to mine the regularity of traditional Chinese medicine(TCM) prescriptions for sick sinus syndrome(SSS) and provide a reference for clinical syndrome differentiation and treatment. The relevant papers were retrieved from CNKI, Wanfang, VIP, and SinoMed with the time interval from inception to January 31, 2023. The relevant information from qualified papers was extracted to establish a library. Lantern 5.0 and Rstudio were used to analyze the latent structure and association rules of TCMs with the frequency ≥3%, which combined with frequency descriptions, were used to explore the rules of TCM prescriptions for SSS. A total of 192 TCM prescriptions were included, involving 115 TCMs with the cumulative frequency of 1 816. High-frequency TCMs include Aconiti Lateralis Radix Praeparata, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Astragali Radix, and Salviae Miltiorrhizae Radix et Rhizoma. The high-frequency medicines mainly had the effects of tonifying, releasing exterior with pungent-warm, and activating blood and resolving stasis. The analysis of the latent structure model yielded 13 hidden variables, 26 hidden classes, 8 comprehensive cluster models, and 21 core prescriptions. Accordingly, the common syndromes of SSS were inferred as heart-Yang Qi deficiency, heart-spleen Yang deficiency, heart-kidney Yang deficiency, Yang deficiency and blood stasis, both Qi and Yin deficiency and blood stasis, and Yin and Yang deficiency. The analysis of association rules predicted 30 strong association rules, among which Ginseng Radix et Rhizoma-Aconiti Lateralis Radix Praeparata had the highest support. SSS is a syndrome with Yang deficiency and Qi deficiency as the root causes and cold, phlegm, and stasis as the manifestations. The clinical treatment of SSS should focus on warming Yang and replenishing Qi, which should be supplemented with the therapies of activating blood and resolving stasis, warming interior and dissipating cold, or regulating Qi movement for resolving phlegm according to the patients' syndromes.

Review
ETHNOPHARMACOLOGICAL RELEVANCE
Glehnia littoralis Fr. Schmidtex Miq. is a well-known perennial herb that is used in traditional medicine in China, Japan and Korea. G. littoralis has the effects of treating the lungs with heat, nourishing yin and blood, and acting as an expectorant. Traditional Chinese medicine (TCM) prescriptions containing G. littoralis have various clinical applications, such as clearing heat, relieving coughs, treating hepatic fibrosis, resolving phlegm, and treating esophagitis.
AIM OF THE REVIEW
This paper aims to provide a comprehensive and productive review of G. littoralis, mainly including traditional application, ethnopharmacology, chemical composition, pharmacological activities, and quality control.
MATERIALS AND METHODS
Literature search was conducted through the Web of Science, ScienceDirect, Springer Link, PubMed, Baidu Scholar, CNKI, and WanFang DATA by using the keywords "Glehnia littoralis", "Radix Glehniae", "Bei Shashen", "Clinical application", "Chemical composition", "Quality control" and "pharmacological action". In addition, information was collected from relevant ancient books, reviews, and documents (1980-2022).
RESULTS
G. littoralis is a traditional Chinese herbal medicine with great clinical value and rich resources. More than 186 components, including coumarins, lignans, polyacetylenes, organic acids, flavonoids, and terpenoids, have been isolated and identified from G. littoralis. The pharmacological activities of more than half of these chemicals are yet unknown. Polyacetylenes and coumarins are the most important bioactive compounds responsible for pharmacological activities, such as antiproliferative, anti-oxidation, anti-inflammatory, antibacterial, antitussive, immune regulation and analgesic. In this study, the progress in chemical analysis of G. littoralis, including thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (MS), and HPLC-MS, were summarized.
CONCLUSION
In this paper reviewed the previous literature regarding ethnopharmacological, phytochemical, pharmacological, and quality evaluation of the processing of G. littoralis was reviewed, providing potential reference information for future investigation and clinical applications. However, research on the relationship between chemical constituents and traditional uses of G. littoralis is lacking, and the comprehensive pharmacological effects and mechanisms of G. littoralis require further detailed exploration. In addition, an efficient method for chemical profiling is still unavailable to obtain potent bioactive markers for quality control. Perfect quality standards, which are also the basis for further drug development of G. littoralis, are urgently needed to ensure its quality and clinical application.

Exploration of biomarkers for efficacy evaluation of traditional Chinese medicine syndromes of acute exacerbation of chronic obstructive pulmonary disease based on metabolomics.
Traditional Chinese medicine (TCM) is effective for the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD); however, there is no objective index for the evaluation of TCM syndrome efficacy. This study aimed to screen biomarkers related to the efficacy of TCM syndrome using metabolomics. We recruited AECOPD patients with phlegm-heat congesting lung (PH)/phlegm-damp amassing lung (PD) syndrome and treated them with Chinese herbal medicine (Qingre Huatan or Zaoshi Huatan granules) in addition to conventional medicine for 7 days. Data on clinical symptoms and sign scores, modified British Medical Research Council (mMRC), COPD assessment test (CAT), and inflammation indicators, including white blood cell (WBC) count, percentage of neutrophil count (NEU%), and C-reactive protein (CRP), were collected before and after treatment to evaluate the therapeutic effect. Serum samples were collected before and after treatment for metabolomic analysis to screen differential metabolites. A total of 69 patients with AECOPD were enrolled, including 41 and 28 patients in the PH and PD groups, respectively. The clinical symptoms and sign scores, CAT, mMRC, NEU%, and CRP levels after treatment were lower than those before treatment in both groups ( < 0.05). Serum metabolomics analysis showed that there were 13 differential metabolites in the PH group and 16 differential metabolites in the PD group before and after treatment ( < 0.05, variable importance projection (VIP) ≥ 1.00). In the PH group, lysophosphatidylcholine (LPC) (16:0), LPC (17:1), LPC (18:3), LPC (18:2), and LPC (17:0) negatively correlated with clinical symptoms and sign scores ( < 0.05); LPC (16:0), LPC (17:1), LPC (16:1), and LPC (17:0) negatively correlated with WBC ( < 0.05) and NEU% ( < 0.05); and LPC (16:0) negatively correlated with CRP levels. In the PD group, L-phenylalanine positively correlated with CRP levels ( < 0.05), and 2-methylbutyroylcarnitine positively correlated with clinical symptoms and sign ( < 0.05) and CAT scores ( < 0.05). DL-carnitine positively correlated with clinical symptoms and sign scores ( < 0.05). Serum metabolites may be potential indicators to objectively evaluate the efficacy of TCM syndromes; however, further large controlled trials are required to verify these findings.

Review
BACKGROUND
Extra-adrenal myelolipoma is an unusual entity, and endobronchial myelolipoma is rarer, which is often ignored by clinicians, delaying the disease and affecting the prognosis.
CASE PRESENTATION
A 71-year-old man with a history of chronic obstructive pulmonary disease (COPD) and type 2 diabetes mellitus, with recurrent fever, cough, and expectoration for more than 2 weeks experienced relief in cough, phlegm reduction, and glycemic control with anti-inflammatory treatment. Further examination revealed that new growths obstructing all lobar bronchi impaired flexible bronchoscope entry. In order to relieve the patient's symptoms, under general anesthesia, we performed liquid nitrogen cryobiopsy at multiple bronchial openings, and then used argon plasma coagulation (APC) to achieve hemostasis. The pathological diagnosis was bronchial myelolipoma. The largest volume of the resected tissue was a mass measuring 0.6 cm × 0.4 cm × 0.3 cm at the bronchial opening of the upper lobe of the left lung. The patient's condition was stable and the symptoms were partially relieved after surgery. No recurrence was observed during the 12-month follow-up, although the long-term treatment efficacy is unknown.
CONCLUSION
Pathological biopsy is key to the diagnosis of endobronchial myelolipoma, and the development of the endobronchial myelolipomas may have been associated with long-term poor control of steroid levels in this patient.

Review
As a commonly used Chinese herbal medicine, Ganoderma applanatum (Pers.) Pat., also known as flat-ling Ganoderma (Chinese name bianlingzhi), old mother fungus (laomujun), and old ox liver (laoniugan), has high medicinal value. It is used as an anti-cancer drug in China and Japan. Besides, it can treat rheumatic tuberculosis and has the effect of relieving pain, clearing away heat, eliminating accumulation, stopping bleeding and eliminating phlegm. The purpose of this review is to analyze the research progress systematically and comprehensively in mycology, mycochemistry and pharmacological activities of G. applanatum, and discuss the prospect of prospective research and implementation of this medicinal material. A comprehensive literature search was performed on G. applanatum using scientific databases including Web of Science, PubMed, Google Scholar, CNKI, Elsevier. Collected data from different sources was comprehensively summarized for mycology, mycochemistry and pharmacology of G. applanatum. A total of 324 compounds were recorded, the main components of which were triterpenoids, meroterpenoids, steroids, and polysaccharides. G. applanatum and its active ingredients have a variety of pharmacological effects, including anti-tumor, liver protection, hypoglycemic, anti-fat, anti-oxidation, antibacterial and other activities. Although G. applanatum is widely used in traditional medicine and has diverse chemical constituents, more studies should be carried out in animals and humans to evaluate the cellular and molecular mechanisms involved in its biological activity.

Renin-angiotensin system mechanism underlying the effect of auricular acupuncture on blood pressure in hypertensive patients with phlegm-dampness constitution: Study protocol for a randomized controlled trial.
BACKGROUND
Phlegm-dampness constitution is a traditional Chinese medicine constitution typically associated with essential hypertension. Previous studies have demonstrated that auricular acupuncture effectively decreases blood pressure and adjusts the constitution. However, the mechanism underlying auricular acupuncture's effect is poorly understood.
METHODS
A non-blinded, randomized controlled trial will be undertaken between September 2022 and May 2023. Eighty essential hypertensive patients with a phlegm-dampness constitution will be randomly allocated to one of two groups. The intervention group will receive eight weeks of auricular acupuncture and regular use of antihypertensive drugs, while the control group will only receive antihypertensive drugs. The primary outcome will be any mean differences in office systolic blood pressure. The secondary outcomes investigations will include proteins of the renin-angiotensin system, office blood pressure of different genotypes, and phlegm-dampness constitution scores.
DISCUSSION
By demonstrating how auricular acupuncture affects the renin-angiotensin system, this research will offer significant new information on the mechanism underlying the action of auricular acupuncture in hypertension. Moreover, the results will provide crucial clinical information on the associations between renin-angiotensin system gene polymorphisms and the antihypertensive effects of auricular acupuncture.

Ling-gui-zhu-gan decoction has significant therapeutic effects in the treatment of diseases related to phlegm and fluid retention. In this study, we aimed to qualitatively characterize the chemical constituents of Ling-gui-zhu-gan decoction in vitro and in vivo by HPLC coupled to Fourier transform ion cyclotron resonance MS, and quantitively determine the contents of typical chemical constituents by HPLC method. As a result, a total of 75 chemical constituents were discovered including 37 flavonoids and their glycosides, 20 saponins, 9 sterols, 3 organic acids and their derivatives, 3 lactones, 2 coumarins, and 1 alcohol. Among them, 17 chemical constituents were specifically identified. Subsequently, an HPLC method was established for simultaneous determination of seven chemical constituents. Finally, a total of 40 prototype components were initially detected by HPLC-MS method in the biological samples of rats after their water extract was orally administrated. Among them, 29, 27, 12, and 32 prototype components were detected in plasma, bile, urine, and feces, respectively. Moreover, 34 metabolites, including 16 phase II metabolites, were detected for the first time. In conclusion, this study lays the foundation for the identification of chemical components in vitro and in vivo and the elucidation of the potential pharmacodynamic components of Ling-gui-zhu-gan decoction.
