ObjectiveTo assess the efficacy and safety of the Qi-regulating and phlegm-removing method(Liu Junzitang Combined with Linggang Wuwei Jiangxintang) for treating acute exacerbations of chronic obstructive pulmonary disease (AECOPD) with increased eosinophils (EOS). MethodsSixty-eight AECOPD patients with increased EOS who were hospitalized in the Department of Pulmonary Diseases of Jinhua Traditional Chinese Medicine Hospital from April 2023 to April 2024 were recruited and randomly assigned to an experimental group (EG) or a control group (CG). Both groups received conventional Western medicine, with the EG additionally receiving Liujunzitang and Linggan Wuwei Jiangxintang. The therapeutic efficacy indicators were measured after the treatment. The main therapeutic efficacy indicators included partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2). The secondary efficacy indicators included the TCM symptom scores, the COPD Assessment Test (CAT) score, the Modified Medical Research Council (mMRC) Dyspnea Scale score, and the length of hospital stay. The indicators were measured at baseline and on days 3 and 7 of intervention. The safety was evaluated based on the adverse events. ResultsBaseline characteristics were not statistically different between the two groups. Compared with CG, EG showed no significant difference in PaO2 (P=0.773), PaCO2 (P=0.632) and or CAT score (P=0.336) at on day 3 but better PaO2 (P=0.004), PaCO2 (P=0.008), and CAT score (P=0.013) were significantly better at on day 7. Compared with CGAfter treatment, EG had lower TCM syndrome scores of than CG EG on day 3 (P=0.005) and day 7 were significantly decreased (P0.001).

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

ObjectiveTo explore the mechanism of total saponins of Dioscoreae Nipponicae Rhizoma (TSDN) in treating gouty arthritis (GA) by regulating cyclooxygenase-2 (COX-2)-mediated M1 macrophage reprogramming by in vivo and in vitro experiments. MethodsIn vivo experiment: 24 male SD rats were randomly allocated into blank, model (GA), TSDN, and celecoxib groups, with 6 rats in each group. After 7 days of administration, pathological changes in the ankle synovial tissue were observed via hematoxylin-eosin (HE) staining. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to quantify the mRNA levels of NOD-like receptor protein 3 (NLRP3) inflammasome, apoptosis-associated speck-like protein (ASC), Caspase-1, COX-2, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in the synovial tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the serum levels of inducible nitric oxide synthase (iNOS), IL-1β, CD86, CD80, CD206, and arginase-1 (Arg-1). In vitro experiment: The GA model was established by lipopolysaccharide (LPS) + MSU induction, and the inhibitor concentration was screened by the methyl thiazolyl tetrazolium (MTT) assay. RAW264.7 cells were allocated into blank, model, TSDN, dexamethasone, COX-2 inhibitor (celecoxib), and TSDN + COX-2 inhibitor groups. The levels of iNOS, IL-1β, CD86, CD80, CD206, and Arg-1 in the cell supernatant of each group were determined by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein levels of NLRP3 inflammasome, COX-2, IL-1β, and TNF-α in each group were determined by Real-time PCR and Western blot, respectively. ResultsIn vivo experiment: compared with the model group, TSDN reduced the mRNA levels of NLRP3 inflammasome, COX-2, IL-1β, and TNF-α in the synovial tissue (P<0.05, P<0.01). ELISA results showed that TSDN lowered the serum levels of iNOS, IL-1β, CD86, and CD80 (P<0.01) while increasing the serum levels of CD206 and Arg-1 (P<0.01). In vitro experiment: compared with the model group, TSDN and inhibitor down-regulated the mRNA levels of NLRP3 inflammasome, COX-2, IL-1β, and TNF-α and the protein levels of NLRP3 inflammasome, COX-2, cleaved IL-1β, and TNF-α (P<0.01). Compared with TSDN alone, TSDN + COX-2 inhibitor further reduced the mRNA and protein levels of the markers above (P<0.01). Compared with the model group, TSDN and COX-2 inhibitor decreased the levels of IL-1β, iNOS, CD80, and CD86 (P<0.01) and increased the levels of CD206 and Arg-1 (P<0.01) in cells. Compared with TSDN alone, TSDN + COX-2 inhibitor reduced IL-1β, iNOS, CD80, and CD86 levels (P<0.05, P<0.01) and elevated CD206 and Arg-1 levels (P<0.01) in cells. ConclusionTSDN can alleviate GA by downregulating COX-2-mediated M1 macrophage reprogramming and suppressing the inflammatory factors.

Dysphagia is a common complication of stroke. Combining the principles of traditional Chinese medicine with modern research findings, it is proposed that "latent pathogen in the cerebral collaterals" constitutes the core pathogenesis of post-stroke dysphagia (PSD). In clinical practice, treatment is tailored according to the location of PSD. During the oral stage, when the pathogen invades the face and mouth, resulting in excessive salivation, acupoints are primarily selected from the foot shaoyin (少阴) kidney channel, in combination with ren mai (任脉) , du mai (督脉), chong mai (冲脉) and the spleen channel, to replenish essence and fill the marrow, dispel dampness and unblock the channels. In the pharyngeal stage, as the pathogen obstructs the throat, disrupting normal swallowing, the therapy emphasizes dredging the shaoyang (少阳) channel and warming and tonifying the jueyin (厥阴) channel, by taking acupoints mainly from the hand and foot shaoyang channels, along with the jueyin channels, so as to soothe the liver and promote bile secretion, regulate and harmonize qi and blood. During the esophageal stage, where the pathogen damages the esophagus, impeding food passage, the treatment emphasizes activating the yangming (阳明) channels and regulating taiyin (太阴) channels; acupoints are mainly selected from the foot yangming stomach channel, along with the taiyin channels, aiming to warm yang, unblock the channels and dispel stasis.

ObjectiveTo explore the quantity-quality transfer process of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(Haliotis discus hannai) by analyzing the physical phase and compositional changes, so as to provide references for the effective control of its quality. MethodsA total of 20 batches of Haliotidis Concha(H. discus hannai) from different habitats were collected and prepared into corresponding calcined products and standard decoction, and the content of CaCO3 of the three samples were determined and the extract yield and transfer rate of CaCO3 were calculated. The changes in elemental composition and their relative contents were investigated by X-ray fluorescence spectrometry(XRF), X-ray diffraction(XRD) was used to study the changes in the phase compositions of the three samples and to establish their respective XRD specific chromatogram. Fourier transform infrared spectrometry(FTIR) was used to study the changes in the chemical composition and content changes of the three samples and to establish their respective FTIR specific chromatogram, while combining hierarchical cluster analysis(HCA), principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) to find the common and differential characteristics, in order to explore the quantity-quality transfer relationship in the preparation process of standard decoction of Haliotidis Concha(H. discus hannai). ResultsThe CaCO3 contents of the 20 batches of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(H. discus hannai) were 93.87%-98.95%, 96.02%-99.97% and 38.29%-51.96%, respectively, and the extract yield of standard decoction was 1.71%-2.37%, and the CaCO3 transfer rate of decoction pieces-standard decoction was 0.68%-1.27%. XRF results showed that the elemental species and their relative contents contained in Haliotidis Concha and its calcined products had a high degree of similarity, and although there was no obvious difference in the elemental species contained in decoction pieces and standard decoction, the difference in the relative contents was obvious, which was mainly reflected in the decrease of the relative content of element Ca and the increase of the relative content of element Na. XRD results showed that Haliotidis Concha mainly contained CaCO3 of aragonite and calcite, while calcined Haliotidis Concha only contained CaCO3 of calcite, and standard decoction mainly contained CaCO3 of calcite and Na2CO3 of natrite. FTIR results showed that there were internal vibrations of O-H, C-H, C=O, HCO3- and CO32- groups in Haliotidis Concha, while O-H, HCO3- and CO32- groups existed in the calcined products and standard decoction. ConclusionThe changes of Haliotidis Concha and calcined Haliotidis Concha are mainly the increase of CaCO3 content, the transformation of CaCO3 aragonite crystal form to calcite crystal form and the absence of organic components after calcination, and the changes of calcined products and standard decoction are mainly the decrease of CaCO3 content and the increase of Na2CO3 relative content. The method established in the study is applicable to the quality control of the shellfish medicines-decoction pieces- standard decoction, which provides a new idea for the study of quality control of dispensing granules of shellfish medicines.

Objective To understand the situation of dental cone beam computed tomography (CBCT) quality control testing phantoms in radiation health technical service institutions in Guangdong province, analyze the differences among different phantoms, and provide a reference for dental CBCT quality control testing. Methods The testing phantoms of 49 radiation health technical service institutions were used as the research objects. The designated CBCT equipment was used for scanning and imaging. The Z-score method was used to evaluate the high-contrast resolution, low-contrast resolution, and distance measurement deviation of each phantom. Results The satisfaction rates of various items for the phantoms in 49 institutions ranged from 85.7% to 100%. The distance measurement deviations of four institutions were “suspicious”, and the high-contrast resolution of four institutions and the distance measurement deviation of one institution were “unsatisfactory”. Conclusion The overall performance of dental CBCT quality control testing phantoms in radiological health technical service institutions in Guangdong province is satisfactory. However, there are still some phantoms with poor results in items such as distance measurement deviation and high-contrast resolution. The structural design, material selection, and manufacturing process of the phantom may all affect the results of quality control testing. Therefore, appropriate phantoms, optimized exposure conditions, and suitable reconstruction algorithms should be used in CBCT quality control testing to ensure accurate and reliable measurements.
