In this paper， by referring to ancient and modern literature， the textual research of Kochiae Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， taste and efficacy， harvesting time， processing and compatibility taboo， so as to provide reference and basis for the development and utilization of related famous classical formulas. According to the investigation， it can be seen that Difuzi was first published in Sheng Nong's Herbal Classic， and has been used as the official name throughout history. It is also known by other names such as Dimai， Dikui， and Luozhou. The mainstream source of Difuzi in materia medica throughout history is the dried ripe fruit of Kochia scoparia， which is consistent throughout history. In the Han dynasty， it was recorded that Kochiae Fructus was produced in Jingzhou（Hubei province）， while modern literature records its distribution throughout the country， so it does not have obvious geoherbalism. The harvesting period of Kochiae Fructus is mostly in the late autumn， and the quality is best when it is full， gray green in color， and no impurities. There are two processing methods for its origin：from the Southern and Northern dynasties to the Ming dynasty， it was dried in the shade， and after the founding of the People's Republic of China， it was dried in the sun. There are few records about the processing of Kochiae Fructus， and its clinical application is mostly based on raw products as medicine. The seedlings are harvested in February of the lunar calendar， and the leaves are taken in April and May， processing in the place of origin is shade drying， the processing methods include burning ash and frying frost， pounding juice and wine soaking. For internal use， it is mostly decocted or mashed， while for external use， it is mostly washed with decoction or taken in a soup bath. Throughout history， it has been recorded that Kochiae Fructus is bitter and cold， and is mainly used for treating bladder fever. After the founding of the People's Republic of China， most of the literature classified it as damp-clearing medicine. Since the 1985 edition of Chinese Pharmacopoeia， it has been recorded that Kochiae Fructus has a pungent and bitter taste， and a cold nature. Returning to the kidney and bladder meridians with functions of clearing heat and dampness， dispelling wind and relieving itching. The clinical contraindications are mainly prohibited for those with deficiency and no dampness and heat. Throughout history， it has been recorded that the taste of the seedlings and leaves is bitter and cold for treatment of dysentery. Since modern times， it has been used to regulate the liver， spleen and large intestine meridians， with functions such as clearing heat and detoxifying， and diuresis. Based on the textual research， it is recommended to use the dried ripe fruit of K. scoparia when developing the famous classical formulas containing Kochiae Fructus， and processing shall be carried out according to the original processing requirements. If the original formula does not specify the processing requirements， the raw products is taken into medicine.

Background Di(2-ethylhexyl) phthalate (DEHP) is the most prevalent environmental endocrine disruptor among phthalate acid esters (PAEs) worldwide. Previous studies have indicated that exposure to DEHP may disrupt glucose metabolism. Objective To investigate the impact of DEHP on glucose homeostasis in rats, focusing on oxidative stress-induced impairment of autophagy in islet β cells. Methods Forty male SD rats were randomly assigned to four groups, receiving DEHP doses of 0, 187, 375, and 750 mg·kg⁻¹ for 12 weeks. Oral glucose tolerance (OGTT) and insulin tolerance tests (ITT) were conducted 24 h after the final exposure. Pancreatic microstructural alterations were assessed using hematoxylin and eosin (HE) staining and transmission electron microscopy (TEM). Commercial ELISA kits were employed to quantify the levels of insulin, adenosine triphosphate (ATP), and adenosine monophosphate (AMP) in rat serum, as well as the protein expression level of activated caspase-3 in pancreatic tissue. Additionally, commercial microplate kits were utilized to measure the concentration of reduced glutathione (GSH) in serum, the activity of superoxide dismutase (SOD) using water-soluble tetrazolium salt-1, the content of malondialdehyde (MDA) by thiobarbituric acid method, and the level of reactive oxygen species (ROS) in pancreatic tissue by chemical fluorescence method. Reverse transcription polymerase chain reaction (RT-PCR) was used to measure sequestosome1 (SQSTM1/p62), Beclin1, microtubule-associated protein 1 light chain 3 (LC3), and cysteinyl aspartate specific proteinase-8 (Caspase-8) mRNA levels. Western blot analysis was applied to detect the protein relative expression levels of p62, Beclin-1, LC3-I, LC3 II, AMPK, p-AMPK, mTOR, p-mTOR, ULK1, and Caspase-8. Results Compared to the 0 mg·kg⁻¹ DEHP group, the 750 mg·kg⁻¹ DEHP group exhibited a significant increase in fasting blood glucose levels at 2, 4, 6, and 12 weeks (P<0.05). The OGTT showed that, following high-glucose gavage, the 187 mg·kg⁻¹ DEHP group had elevated blood glucose at 30 min (P<0.05), the 375 mg·kg⁻¹ DEHP group showed increased glucose levels at 15, 30, and 180 min (P<0.05), and the 750 mg·kg⁻¹ DEHP group exhibited elevated levels at 15, 30, 60, and 180 min (P<0.05). The 375 and 750 mg·kg⁻¹ DEHP groups demonstrated significantly increased OGTT area under the curve (AUC) values (P<0.05). In contrast, ITT results indicated no significant differences in blood glucose levels or AUC among the DEHP exposure groups at all time points (P>0.05). Compared to the 0 mg·kg⁻¹ DEHP group, the 750 mg·kg⁻¹ DEHP group exhibited significantly higher HOMA-IR levels and markedly lower HOMA-ISI values (P<0.05). HE and TEM showed that in each DEHP exposure group, the number of islet cells decreased, the islet area reduced, and chromatin condensation occurred. The endocrine granules in the cytoplasm of islet β cells decreased, and there were varying degrees of widening of the nuclear membrane gap, flattening and expansion of the Golgi complex, and expansion of the endoplasmic reticulum. Ribosome separation was observed, and autophagosomes were visible. In the 375 and 750 mg·kg⁻¹ DEHP groups, the mitochondria were deformed to varying degrees, and some cristae structures disappeared, presenting vacuolization. Moreover, the chromatin condensation in the nuclei was more severe in the 750 mg·kg⁻¹ DEHP group. The serum SOD activity was significantly elevated in the 750 mg·kg⁻¹ DEHP group (P<0.05). Both the 375 mg·kg⁻¹ and 750 mg·kg⁻¹ DEHP groups exhibited a significant increase in the relative ROS content in pancreatic tissue (P<0.05). In DEHP-treated groups, the MDA content increased (P<0.05), while the GSH content decreased (P<0.05). Additionally, in the 750 mg·kg⁻¹ DEHP group, the AMP/ATP ratio in serum was significantly raised (P<0.05), and the expression of cleaved Caspase-3 protein in pancreatic tissue was also significantly increased (P<0.05). The relative mRNA levels of p62, Beclin-1, LC3, and Caspase-8 in the pancreatic tissue of rats exposed to DEHP were significantly elevated (P<0.05). The relative expression levels of p-AMPK/AMPK, p-ULK1/ULK1, and Beclin-1 proteins in the DEHP-treated groups were significantly increased (P<0.05). In the 375 mg·kg⁻¹ and 750 mg·kg⁻¹ DEHP treatment groups, the relative expression levels of p62, LC3 II/LC1, and Caspase-8 proteins were significantly increased (P<0.05), while the relative expression level of p-mTOR/mTOR was significantly decreased (P<0.05). Conclusion DEHP can disrupt glucose homeostasis by inducing oxidative stress, which subsequently activates autophagy via the ROS/AMPK/ULK1 pathway, impairing autophagic flux and promoting apoptosis of islet β cells, ultimately decreasing their function and number.

In this paper， by referring to ancient and modern literature， the textual research of Cnidii Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， nature and flavour， efficacy， harvesting and processing， compatibility taboo and others， so as to provide reference and basis for the development and utilization of the relevant famous classical formulas. After textual research， it can be verified that Cnidii Fructus was first published in Sheng Nong's Herbal Classic， the materia medica of all dynasties was named Shechuangzi， and there are also aliases such as Shesu， Shemi， and Qiangmi. The main source for generations was the dried ripe fruit of Cnidium monnieri， and ancient and modern consistent. From the Eastern Han dynasty to Tang dynasty， the origin of Cnidii Fructus was Zibo， Shandong province. During the Five dynasties， it expanded to Yangzhou in Jiangsu province and Xiangyang in Hubei province， the Song dynasty added Shangqiu in Henan province， and it was considered that Yangzhou， Xiangyang and Shangqiu were its genuine producing areas. It was more widely distributed in Ming and Qing dynasties. After the founding of the People's Republic of China， the origin is clearly distributed throughout the country. For its quality evaluation， generally full grain， gray yellow color， strong aroma is the best. The harvesting period in the past dynasties was mostly the fifth lunar month， and the fruit was collected to remove impurities and dry. The mainstream processing in producing area of the past dynasties was net selection of raw products， mixing and steaming with the juice of Rehmanniae Radix and stir-frying were the mainstream processing methods in the past， there were also stir-frying with honey， stir-frying with salt and rice wine， immersing and steaming with rice wine and other methods. In recent times， it has been used in raw products as medicine. Sheng Nong's Herbal Classic recorded Cnidii Fructus was bitter， Supplementary Records of Famous Physicians recorded its acrid for the first time. It was recorded in the Ming dynasty that its nature was warm， acted on the kidney meridian， and had small toxicity. After the founding of the People's Republic of China， most of the literature classified it as a medicine to attack poison， kill insects and relieve itching with the functions of dispelling pathogenic wind and removing dampness， destroying parasites and elieving itching， warming kidney and activating Yang. Clinical contraindications are mainly contraindicated for people with damp-heat from the lower-jiao or kidney heat. Based on the textual research， it is suggested that when developing the famous classical formulas containing Cnidii Fructus， the source shall be the dried ripe fruit of C. monnieri， and then it shall be processed according to the original formulas. If there is no requirement for processing in the formulas， the raw products can be taken into medicine.

This article discusses the important role and practical experience of Guangxi Zhuang Autonomous Region as a bridgehead between China and the Association of Southeast Asian Nations (ASEAN) in the joint prevention and control of cross-border infectious diseases between China and Vietnam. The cross-border transmission of infectious diseases has been effectively managed in Guangxi Zhuang Autonomous Region through a package of strategies, including government leadership, construction of the joint prevention and control mechanism, establishment of dialogue platforms, collaboration of scientific researches, and personnel exchange and training; however, there are still challenges. Further deepening of collaboration is required to meet future needs for infectious disease prevention and control.

Rapid and ultrasensitive detection of pathogen-associated biomarkers is vital for the early diagnosis and therapy of bacterial infections. Herein, we developed a close-packed and ordered Au@AgPt array coupled with a cascade triggering strategy for surface-enhanced Raman scattering (SERS) and colorimetric identification of the Staphylococcus aureus biomarker micrococcal nuclease (MNase) in serum samples. The trimetallic Au@AgPt nanozymes can catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) molecules to SERS-enhanced oxidized TMB (oxTMB), accompanied by the color change from colorless to blue. In the presence of S. aureus, the secreted MNase preferentially cut the nucleobase AT-rich regions of DNA sequences on magnetic beads (MBs) to release alkaline phosphatase (ALP), which subsequently mediated the oxTMB reduction for inducing the colorimetric/SERS signal fade away. Using this "on-to-off" triggering strategy, the target S. aureus can be recorded in a wide linear range with a limit of detection of 38 CFU/mL in the colorimetric mode and 6 CFU/mL in the SERS mode. Meanwhile, the MNase-mediated strategy characterized by high specificity and sensitivity successfully discriminated between patients with sepsis (n = 7) and healthy participants (n = 3), as well as monitored the prognostic progression of the disease (n = 2). Overall, benefiting from highly active and dense "hot spot" substrate, MNase-mediated cascade response strategy, and colorimetric/SERS dual-signal output, this methodology will offer a promising avenue for the early diagnosis of S. aureus infection.

Small urban wetlands are widely distributed and susceptible to human activities, serving as important sources and sinks of carbon. Microorganisms play a crucial role in carbon cycle, while limited studies have been conducted on the microbial diversity in small urban wetlands and the functions of microbiome in carbon fixation and metabolism. To probe into the microbiome-driven carbon cycling in small urban wetlands and dissect the composition and functional groups of microbiome, we analyzed the relationships between the microbiome structure, element metabolism pathways, and habitat physicochemical properties in sediment samples across three small wetlands in Huzhou City, and compared them with natural wetlands in the Zoige wetland. High-throughput sequencing of 16S rRNA gene amplicons and metagenomics was employed to determine the species and functional groups. Sixty medium to high-quality metagenome-assembled genomes (MAGs) were constructed, including 55 bacterial and 5 archaeal taxa, and their potential in driving elemental cycles were analyzed, with a focus on carbon fixation. Several bacterial species were found to encode a nearly complete carbon fixation pathway, including the Calvin cycle, the reductive tricarboxylic acid cycle, the Wood-Ljungdahl pathway, and the reductive glycine pathway. There were several potential novel carbon-fixing bacterial members, such as those belonging to Syntrophorhabdus (Desulfobacterota) and UBA4417 (Bacteroidetes), which had high relative abundance in the wetland microbiome. Unveiling the genetic potential of these functional groups to facilitate element cycling is of great scientific importance for enhancing the carbon sequestration capacity of small urban wetlands.
