This article systematically reviews and verifies the name, origin, production area, quality evaluation, harvesting, processing and other aspects of Cynanchi Atrati Radix et Rhizoma(CARR) by consulting relevant ancient and modern literature, in order to provide a basis for the development and utilization of famous classical formulas containing this herb. Through textual research, Baiwei has been the official name for CARR, though it also bears alternative names such as Chuncao, Popo Zhenxianbao, Longdan Baiwei. The mainstream base is the roots and rhizomes of Cynanchum atratum. Historical records indicate primary producing areas include Shandong, Anhui, Jiangsu, Shaanxi and Shanxi. Since the late Ming dynasty, varieties from Juxian, Yishui and Rizhao in Shandong have been highly regarded as authentic, commonly known as eastern Baiwei. Since modern times, its quality has been summarized as fine, slender, and straight fibrous roots, pale yellow exterior, whiter interior, and dryness with easy breakability are considered superior. The harvesting time before the Song dynasty was on the third day of the third lunar month, but after the Song dynasty, harvesting was possible in both spring and autumn. The initial processing methods of CARR in ancient times included drying in the shade, removing Lu(the little rhizomes which are on tap of roots), and removing mustaches, modern methods involve washing and sun-drying. During the Northern and Southern dynasties, processing methods included steaming. In the Song dynasty, drying and light stir-frying were predominant, while wine washing emerged in the Ming dynasty. Modern practices primarily involve using raw, stir-frying or honey processing. Regarding the medicinal properties of CARR, both ancient and modern texts agree it has a bitter and salty taste and is non-toxic. Records prior to the Qing dynasty predominantly describe its nature as extremely cold, while mainstream herbal texts after the Qing dynasty generally characterize it as cold. Before the Ming dynasty, there were no records of its meridian tropism. It was not until the Qing dynasty that it was recorded in the lung meridian. Modern records mainly refer to the stomach, liver, and kidney meridians. Throughout history, its main functions have been to clear heat, diuresis, nourish Yin, and replenish essence, primarily treating Yin deficiency and fever syndrome. Based on the research results, it is suggested that when developing famous classical formulas containing CARR, the dried roots and rhizomes of C. atratum can be selected as its medicinal source. If there are no specific processing requirements, raw products can be selected as medicine. If the processing requirements are specified, corresponding processed products can be selected as medicine according to the original formula requirements.

This article systematically analyzed the historical evolution of the name, origin, harvesting and others of Longan Arillus by referring to the ancient and modern literature, in order to provide a foundation for developing famous classical formulas containing this herb. After textual research, it indicated that Longan Arillus was first recorded under the name of longan in Shennong Bencaojing of the Han dynasty. During the Ming and Qing dynasties, Longan Arillus gradually replaced longan as the standard name recorded in the materia medica, with additional aliases including Yizhi, Lizhinu and Yuanyan. The source of Longan Arillus used in the past dynasties was the arillus of the Sapindaceae plant Dimocarpus longan. The production regions recorded in the past dynasties were mainly Fujian, Guangdong, Guangxi, Hainan, Sichuan and others. Since the Qing dynasty, Longan Arillus produced in Fujian, Guangdong and Guangxi have been regarded as the finest and authentic varieties, with Fujian, Guangxi, and Guangdong remaining the primary authentic production areas today. In ancient times, the fruits were primarily harvested in August of the lunar calendar. However, modern longan cultivation typically involves harvesting ripe fruits during summer and autumn. Post-harvest processing involves removing moisture through sun-drying or baking before drying for medicinal use. Throughout history, processing methods have primarily focused on raw product, though techniques such as wine soaking and powdering have also been employed. Since modern times, it has been concluded that its quality is the best one with thick flesh, sweet taste, brownish-yellow color and tender texture. Longan Arillus possesses a sweet and warm nature, entering the heart and spleen meridians. Its primary functions are tonifying the heart and spleen, nourishing the blood and calming the spirit, which is consistent in ancient and modern times. Based on the textual research, it is suggested to use the arillus of D. longan when developing the famous classical formulas containing Longan Arillus. Processing methods should be selected according to the formula requirements, where no specific processing is indicated, the raw products is recommended for medicinal use.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, producing area, harvesting and processing, nature, flavor and efficacy of Piperis Longi Fructus by referring to the materia medica, medical books, and prescription books of past dynasties, combined with the relevant modern literature, in order to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the herbal textual research, the name of Piper longum first appeared in Nanfang Caomuzhuang, and it also has other aliases such as Biboli, Halou, and Hujiaohua. Historically, the origin of Piperis Longi Fructus has been P. longum of the Piperaceae family. In ancient times, both the fruit and root were used as medicine, and since the Republic of China, the fruit has been mainly used as medicine. The medicinal part is the dried, nearly ripe or ripe fruit spikes. Piperis Longi Fructus is native to India and has been introduced into China since the Tang dynasty. In the Ming dynasty, Bencao Pinhui Jingyao clearly stated that the genuine producing area was "Duanzhou", present-day Zhaoqing in Guangdong province. Nowadays, it is planted in Guangdong, Guangxi, Hainan, Yunnan and other regions. Historically and currently, harvesting occurs in autumn. The ancient processing method uniformly involved removing the stems, soaking in the sourest vinegar overnight, baking, and scraping off the peels and grains with a knife until clean. In modern times, impurities are removed, and it is dried in the sun and crushed when used. The properties, functions and applications of P. longum are basically the same in ancient and modern times. It tastes pungent, is warm in nature, and non-toxic. It has the effects of warming the middle-jiao to dispel cold, lowering Qi and relieving pain, and is used for cold pain in the epigastrium and abdomen, vomiting, diarrhea, chest pain, headache, and toothache. Based on the research results, it is recommended that when developing famous classical formulas containing Piperis Longi Fructus, the dried nearly ripe or ripe fruit spikes of P. longum should be used. If there are no clear processing requirements, it is recommended to use the raw products for medicinal use, and the specific processing methods can refer to the relevant requirements under Piperis Longi Fructus in the 2025 edition of the Pharmacopoeia of the People's Republic of China. If processing requirements such as soaking in vinegar and peeling are clearly specified, it is recommended to follow the ancient methods.

Background Occupational groups are facing a "dual health threat". Research indicates that enhancing the occupational health literacy (OHL) of workers is crucial for safeguarding their health and well-being. However, at present, the research on OHL in China is still in its infancy and there is an urgent need to carry out systematic studies. Objective To analyze the OHL level and influencing factors of key industry groups in Huangshan City, and to provide a basis for targeted intervention activities. Methods From 2022 to 2023, a stratified cluster random sampling method was used to select 621 frontline workers from 20 companies in four industries: non-metallic mineral mining and dressing, textile and apparel, rubber and plastic products, and non-metallic mineral products in Huangshan City. The participants were asked to anonymously complete the National Key Population Occupational Health Literacy Monitoring Survey Personal Questionnaire. The overall and 4 dimension levels of OHL were calculated according to the "2022 Calculation Standards for Occupational Health Literacy Levels of Key Populations". The OHL level was defined as the proportion of the target population possessing adequate OHL (indicated by an overall or dimension-specific score rate ≥80% on the questionnaire). Results A total of 621 workers were surveyed during the study period, with 597 valid questionnaires collected, resulting in an effective rate of 96.14%. The participants were mainly frontline workers in small enterprises, presenting the pattern of "three lows and one long". The male-to-female ratio was 1.16∶1. The overall OHL level of the participants was 45.06% during the study period. The dimension-specific levels of occupational health legal knowledge, basic knowledge, basic skills, and healthy working methods and behaviors were 50.25%, 73.53%, 30.49%, and 60.13%, respectively. There were statistically significant differences in the overall OHL level and the four dimension-specific levels among workers across different industries (P<0.05), with the lowest overall OHL level in the textile and apparel industry (32.06%). The results of logistic regression analysis showed that compared with those with a monthly income of less than

Objective:
To analyze the one year follow up changes and influencing factors of anisometropia among primary school students in Beihai, so as to provide data support for formulating targeted prevention and control strategies.
Methods:
In 2023 and 2024, visual acuity and refractive screening were conducted on primary school students in Beihai. A cohort matching method was used based on unique identifiers to link data from 2023 (baseline) Grades one to five with those from 2024 (follow up) Grades two to six, obtaining a total of 59 743 complete datasets. McNemar test and generalized estimating equations(GEE) model were employed to analyze the changing patterns of anisometropia.
Results:
The detection rate of anisometropia among primary school students in Beihai increased from 10.88% in 2023 to 12.30% in 2024 ( χ 2=97.12, P <0.01). Among them, the detection rate in Grade 1 decreased from 8.82% in 2023 to 7.50% in 2024, Grade 3 increased from 10.15% to 11.52%, Grade 4 increased from 12.10 % to 15.22%, Grade 5 increased from 14.61% to 17.88% ( χ 2=16.51,18.03,95.52,95.95,all P <0.05). The GEE results showed that the risk of anisometropia development was higher in girls than in boys ( OR =1.15), the risk of anisometropia increased by 16% with each 1 year increment in age ( OR =1.16) among primary school students, the risk of anisometropia development in Grade 5 was 2.20 times higher than that in Grade 1 ( OR =2.20)(all P <0.05). In lower grades, only the baseline anisometropia status in lower grades had a statistically significant effect on anisometropia among primary school students( OR =59.09), while the positive effects of gender and age difference gradually emerged and strengthened in middle and higher grades (all P <0.05).
Conclusions
The detection rate of anisometropia among primary school students in Beihai shows dynamic changes and influencing factors vary by grade level. It is necessary to develop stratified prevention and control strategies tailored to different grades.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material, covering aspects such as nomenclature, origin, geographical distribution, harvesting and processing methods, quality assessment, therapeutic effects and indications, by consulting ancient herbal texts, medical compendia, and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty, with Zhuli being the standard name used throughout history, alongside aliases like Zhuzhi, Zhuyou and Huoquan. Historically, the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis(Danzhu), although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou(present-day Chengdu and surrounding areas in Sichuan) and the Wuling region(between present-day Hunan, Guangdong, Guangxi and Jiangxi provinces), while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally, Bambusae Succus was harvested from bamboo that had grown for exactly one year, today, it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation, whereas modern industrial production employs dry distillation, reflux extraction, and percolation. In terms of quality evaluation, ancient texts considered a sweet taste to be superior, while today, clarity and transparency are prioritized. Historically, Bambusae Succus was characterized as sweet and cold nature, targeting the lung and stomach meridians, with uses evolving from clearing heat and resolving phlegm to nourishing Yin, moistening dryness, and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet, bitter, and cold in nature, affecting the heart, liver, and lung meridians, with functions including clearing heat, resolving phlegm, and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion, lung heat with phlegm congestion, convulsions, epilepsy, excessive phlegm in febrile diseases, high fever with thirst, irritability during pregnancy, and tetanus, with more clearly defined applications. Based on the results of the research, it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus, the one-year-old Phyllostachys nigra var. Henonis, which has been highly praised throughout history, should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore, in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste, and reasonable modern quality control standards should be established.

Objective: To establish a rapid, accurate, and decentralized workflow for bacterial whole-genome sequencing (WGS) and risk profiling within the shelf-life of platelet concentrates, and to characterize the species, virulence, antimicrobial resistance (AMR), and immune evasion mechanisms of co-existing bacteria in qualified platelet products, thereby providing a scientific basis for transfusion safety assessment. Methods: Three units of platelet concentrates, which tested negative by routine bacterial screening, were collected from the Chengdu Blood Center between May and June 2025. Samples were enriched at 37℃under six aerobic and nine anaerobic conditions for 7 days. Using a culturomics strategy, aliquots were plated for isolation on days 1, 3, 5, and 7 to obtain cultivable isolates, with negative culture controls included to exclude contamination. High-molecular-weight genomic DNA was extracted via mechanical grinding, purified, and size-selected. Sequencing libraries were constructed and sequenced on the G-seq500 single-molecule nanopore sequencing platform. Genomes were assembled using Flye and polished with NextPolish, with quality evaluated by BUSCO and CheckM. Taxonomic identification was performed using GTDB-Tk. Functional annotation and database comparisons were conducted to analyze virulence factors, AMR genes, and genes related to immune evasion and environmental adaptation. Results: Viable bacteria were successfully isolated from all three qualified platelet units within their shelf life. The isolates were identified as Bacillus albus, Niallia taxi, and Staphylococcus warneri. Nanopore sequencing generated 92 227-109 813 reads (totaling 680-758 Mb) with an N50 of 7 625-8 584 bp and Q20/Q30 scores of 97%/93%, respectively. All three genomes were assembled into complete circular chromosomes with 1-3 plasmids, achieving >93% completeness. Functional analysis revealed that B. albus carried multiple hemolysins, metalloproteases, and multidrug resistance genes, indicating the highest potential pathogenicity and AMR risk. S. warneri exhibited a typical multidrug resistance profile and regulatory network characteristic of coagulase-negative staphylococci, suggesting intermediate virulence. N. taxi harbored few canonical virulence factors and lacked functional AMR determinants, presenting a "low-virulence, low-resistance" profile. Notably, all three strains were enriched in genes encoding antimicrobial peptide resistance systems (e.g., dltABCD, mprF, GraRS, BceAB) and antioxidant enzymes, suggesting a strong capacity to withstand immune stress in the blood environment. Conclusion: Viable bacteria can be recovered from qualified platelet concentrates that test negative by routine screening. Nanopore WGS enables rapid strain-level identification and comprehensive risk profiling of virulence, resistance, and immune adaptation traits. The functional repertoires of these "co-existing" isolates range from environmental adaptation to potential pathogenicity, representing an underappreciated risk for transfusion-transmitted infections in susceptible recipients.

OBJECTIVE To investigate the effects of galangin on rheumatoid arthritis (RA) in rats by regulating the Janus kinase 3 (JAK3)/signal transducer and activator of transcription 3 (STAT3) pathway. METHODS Fifty male SD rats were taken, and an emulsion composed of bovine type Ⅱ collagen and Freund’s complete adjuvant was injected subcutaneously to establish an induced arthritis model. The rats that were successfully modeled were randomly divided into model group, low, medium and high dose groups of galangin (1, 5, 15 mg/kg), and methotrexate group (positive control, 2 mg/kg), with 10 rats in each group. Another 10 normal rats were taken as the normal group. Starting from the 15th day of modeling, each group of rats was gavaged with the corresponding drug solution or normal saline containing 0.5% Tween 80 once a day for 28 consecutive days. The arthritis index (AI) scores and paw volume of rats were compared before and after gavage administration. Twenty-four hours after the last administration, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-4 and IL-10 were determined, the pathological changes in ankle joint synovial tissue were observed, and the protein expressions of UNC-51 like kinase 1 (ULK1), Beclin-1, microtubule-associated protein 1 light chain 3 (LC3), B cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), caspase-3, JAK3, phosphorylated JAK3 (p-JAK3), STAT3 and phosphorylated STAT3 (p-STAT3) in the synovial tissue of the ankle joint were detected, as well as the fluorescence intensity of LC3-positive areas. RESULTS Compared with the model group, the pathological changes such as cellular proliferation of ankle joint synovial tissue and infiltration of inflammatory cells in rats of each administration group showed improvement. Moreover, their AI scores and paw pad volumes (on day 28 after gavage), the levels of IL-6 and TNF-α, the protein expression of Bcl-2, and the phosphorylation levels of JAK3 and STAT3 were all significantly reduced ( P <0.05). The levels of IL-4 and IL-10, the protein expressions of ULK1, Beclin-1, Bax, caspase-3 and LC3, as well as the fluorescence intensity of LC3-positive areas, were all significantly increased ( P <0.05). Moreover, the effect of galangin was in a dose-dependent manner ( P <0.05). CONCLUSIONS Galangin can induce sustained autophagy in synovial tissue cells of RA rats, promote cell apoptosis, inhibit synovial cell proliferation, and alleviate persistent inflammatory responses. The above anti-RA effects may be related to the inhibition of the JAK3/STAT3 pathway.
