ObjectiveBy comparing the composition and content of volatile components in raw products, wine-washed products and wine-fried products of Ligusticum sinense cv. Chaxiong rhizome(LSCR), to investigate the influence of wine processing on the volatile components of LSCR, in order to provide a basis for the development of quality standards for LSCR and its processed products. MethodsElectronic nose was used to identify the odors of LSCR, wine-washed and wine-fried LSCR, and their volatile components were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the relative mass fractions of these components were determined by peak area normalization method. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the obtained sample data by SIMCA 14.1 software, and the differential components of LSCR, wine-washed and wine-fried LSCR were screened according to the variable importance in the projection(VIP) value>1. Pearson correlation analysis was used to explore the relationship between volatile differential flavor components and electronic nose sensors. ResultsElectronic nose detection results showed that there were significant differences in the odors of LSCR, wine-washed and wine-fried LSCR, mainly reflected in the sensors S2, S4, S5, S6, S11, S12, S13. And a total of 62 compounds were identified from LSCR and its wine-processed products, among which 46, 50 and 51 compounds were identified from LSCR, wine-fried and wine-washed LSCR, respectively. There were 21 differential components between the raw products and wine-fried products, of which 10 components were increased and 11 were decreased after processing. There were 20 differential components between the raw products and wine-washed products, of which 11 constituents increased and 9 decreased after processing. There were 17 differential components between the wine-wash products and wine-fried products. Compared with the wine-washed products, the contents of 13 components in the wine-fried products increased, and the contents of 4 components decreased. The increasing trend of the content of phthalides in the wine-washed products was more obvious than that in the wine-fried products, but the content of total volatile components was higher in the wine-fried products than the wine-washed products. Correlation analysis showed that there were different degrees of correlation between the 7 differential sensors of electronic nose and 24 differential volatile components, mainly phthalides and olefins. ConclusionThe odor and the content of volatile components in LSCR changed obviously after wine processing, and n-butylphthalide, Z-butylidenephthalide and E-ligustilide can be used as the candidate differential markers of volatile components in LSCR before and after wine processing.

OBJECTIVE To screen the primary processing methods of Ligusticum sinense slice based on differential metabolites, and provide theoretical basis for the scientific processing of L. sinense. METHODS Using 13 groups of L. sinense slice processed by fresh-cutting or traditional methods as samples, UHPLC-QE-MS was employed for metabolite identification. Multivariate statistical analysis was applied to screen differential metabolites among the 13 sample groups, analyzing the effects of washing, soaking, drying methods, and drying cycles on both the relative expressions of differential metabolites and the contents of carboxylic acids and their derivatives in the samples (to reflect the total amino acid content). RESULTS Principal component analysis and partial least squares-discriminant analysis both showed significant intergroup differences among the 13 sample groups. A total of 688 differential metabolites were screened from the 13 sample groups, with carboxylic acids and their derivatives showing the highest proportion. The relative expression levels of phosphatidylcholine significantly increased after washing treatment, while tryptophan expression significantly decreased after soaking treatment. Samples dried at 50-60 ℃ showed significantly increased expression of psoralen, whereas those dried at 40 ℃ showed significantly decreased expression of methyl -p- methoxycinnamate. Both washing and soaking treatments significantly reduced the total amino acid content in samples, while secondary drying significantly increased it. The three controlled-temperature drying methods maintained relatively stable total content of amino acids in samples. CONCLUSIONS The optimal processing protocol for L. sinense slice is as follows: fresh L. sinense slice should be freshly cut at the production site, undergo quick washing after soil removal, and be dried twice at 40 ℃ (before and after slicing).

Objective To evaluate the efficacy and safety of Mirabegron combined with transcutaneous tibial nerve stimulation (TTNS) in the treatment of drug-refractory overactive bladder (OAB), so as to alleviate patients'symptoms, improve their quality of life with optimized treatment plan, and provide reference for clinical practice. Methods A retrospective analysis was conducted on 56 patients with drug-refractory OAB treated at the Department of Urology of Gansu Provincial Hospital during Jan.2023 and Dec.2024. Based on the treatment methods, the patients were divided into two groups:the TTNS group and the combined treatment group, with 28 patients in either group. The daytime urination frequency, nocturia frequency, urgency episodes, urinary incontinence, functional bladder capacity (FBC), OAB symptom scores (OABSS), and incontinence quality of life questionnaire (I-QoL) scores were collected before and after treatment. The therapeutic efficacy was evaluated using the Nimodipine method. Results After 12 weeks of treatment, the 24-hour urination indicators in both groups including daytime urination frequency, nocturia frequency, urgency episodes and FBC, as well as OABSS and I-QoL scores, showed a significant improvement compared to baseline (P<0.001). The combined treatment group exhibited fewer urgency episodes than the TTNS group [ (1.07±0.66) times/24 h vs. (1.64±0.62) times/24 h, P<0.05]. However, no statistically significant differences were observed between the two groups in other urinary parameters (P>0.05). The total effective rate in the combined treatment group was 96.43%, which was significantly higher than that in the TTNS group (82.14%, P<0.05). During treatment, one patient (3.57%) in the TTNS group experienced mild skin allergy, which recovered following symptomatic management. Conclusion The combination of TTNS and Mirabegron in drug-refractory OAB not only alleviates clinical symptoms and improves quality of life, but also shows superior efficacy in reducing urgency episodes. This approach is a safe and effective treatment option.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a refractory condition characterized by chronic inflammation of the bladder wall, disruption of the urothelial barrier, and neural sensitization. Current therapies, such as oral pentosan polysulfate sodium (PPS) or intravesical hyaluronic acid instillations, offer limited efficacy due to transient effects and an inability to reverse tissue fibrosis. Platelet-rich plasma (PRP), a regenerative medicine approach, has demonstrated significant therapeutic potential in urological disorders through the synergistic actions of its multiple growth factors. This review summarizes the latest advances in PRP therapy for IC/BPS, revealing that the underlying mechanisms primarily involve the release of diverse growth factors, suppression of inflammatory responses, restoration of the urothelial barrier, and modulation of nerve axonal regeneration. Clinically, PRP therapy significantly alleviates symptoms including pelvic/bladder pain, urinary frequency, nocturia episodes, and improves patients'quality of life. Furthermore, it offers advantages such as convenient administration, a favorable safety profile, and strong feasibility, presenting new therapeutic methods and options for the clinical treatment of IC/BPS.

ObjectiveTo analyze the effects of new integration processing method in producing area and traditional method on the composition and pharmacological action of Polygoni Multiflori Radix Praeparata(PMRP), and to illustrate the advantages of toxicity reducing and efficacy enhancing of the decoction pieces prepared by the new method. MethodFresh Polygoni Multiflori Radix(PMR) was taken from Dao-di producing area, and was processed by new integration processing method in producing area(steaming with black bean juice under pressure of 0.1 MPa and temperature at 120 ℃ for 10.5 h) and traditional method(steaming with black bean juice under water for 36 h), respectively. Samples were collected during the processing process of the two methods, For new method, the samples were collected at 0.5, 3, 5.5, 8, 10.5 h, separately. For traditional method, the samples were collected every 4 h. High performance liquid chromatography(HPLC) was used to establish fingerprint and identify common peaks, the content of polysaccharides was determined by anthrone-sulfuric acid colorimetry at 627 nm, and the contents of anthraquinones and stilbene glycosides in different processed products were determined according to the methods under the item of determination of PMR and PMRP in the 2020 edition of Chinese Pharmacopoeia. In pharmacological experiments, 90 SD rats were randomly divided into 9 groups with 10 in each group(half of male and half of female), including the blank group, and raw products, 24 h processed products under atmospheric pressure, 30 h processed products under atmospheric pressure, 8 h processed products under high pressure groups with low and high dosages(4.125, 16.5 g·kg-1). Rats were given the drug by gavage for 29 d with once a day, blood was collected from the abdominal aorta after the last administration, and the serum was isolated, the body mass and liver mass of rats were weighed and the organ index was calculated. The pathological change of liver tissue was observed by hematoxylin-eosin(HE) staining, and biochemical methods were used to detect the contents of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), γ-glutamyltransferase(GGT), lactic dehydrogenase(LDH) in serum which used as liver function indicators and the levels of superoxide dismutase(SOD), malondialdehyde(MDA), glutathione peroxidase(GSH-Px) in brain tissues which used as oxidation indicators. ResultA total of 14 common peaks were identified in the fingerprint of PMR, PMRP prepared by new method and traditional method, and three of the peaks were designated as stilbene glycoside, emodin and emodin methyl ether, respectively. The characteristic peak areas of each processed products changed significantly from 0 min to 25 min, indicating that different processing methods had an effect on the contents of components with high polarity in PMRP, and the trend of the changes of the two methods was similar, with the higher degree of change in the new method. The determination results showed that compared with the traditional method, the content of polysaccharide(a kind of beneficial component in PMRP obtained by the new method) significantly increased, while the contents of stilbene glycoside and bound anthraquinone(liver-damaging ingredients) significantly decreased. The pharmacological results showed that compared with the blank group, AST and LDH levels of male rats in the low and high dose groups of 24 h processed products under atmospheric pressure and AST level of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly reduced(P<0.05, P<0.01), while compared with the raw product groups with the same dose, AST and LDH levels of male rats in the low dose group of 30 h processed products under atmospheric pressure were significantly reduced(P<0.05, P<0.01), the AST levels of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly decreased(P<0.01), and there was no statistical significance in the differences of biochemical indexes of female rats in each administration group as compared with those of the blank group. ConclusionThe new integration processing method in producing area of PMRP can reach the quality of relevant regulations in 8 h. The processed products obtained by this method have more advantages than the traditional method in terms of toxicity reducing and efficacy enhancing, and energy saving to avoid the loss of ingredients, which can provide ideas for the production of high-quality decoction pieces of PMRP, and the integration processing method in producing area of other roots and rhizomes of traditional Chinese medicines.

ObjectiveBy exploring the volatile components, polysaccharide composition and changes in the contents of five carbohydrate components of Polygonatum cyrtonema rhizoma before and after processing, and then the effect of yellow rice wine on the odour formation of P. cyrtonema rhizoma was investigated. MethodThe volatile components of P. cyrtonema rhizoma before and after processing were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and sample data were subjected to principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) using SIMCA 14.1, then the differences between these components of P. cyrtonema rhizoma before and after processing were screened according to the principle of variable importance in the projection(VIP) value>1. Crude carbohydrate components in raw and wine-processed P. cyrtonema rhizoma were subjected to oxime and silylation, the carbohydrate components were analyzed by gas chromatography-mass spectrometry(GC-MS/MS), and the relative contents of various components were calculated by peak area normalization, then quantitative analysis of four carbohydrate components was also carried out. ResultA total of 23 volatile components were identified from the raw products and the wine-processed products, including 15 components in raw products and 20 components in wine-processed products. Among them, 2-methylbutyraldehyde and isovaleraldehyde had a sweet odor and their contents increased after processing, but the contents of hexanal and caproic acid decreased, new components such as 2-acetylfuran and 5-methylfuranal were produced after processing. PCA and OPLS-DA results showed that there were significant differences between raw products and the wine-processed products, a total of 13 differential compounds were screened out, of which 7 showed an upward trend in relative content and 6 showed a downward trend. A total of 7 carbohydrate components, including 5 monosaccharides and 2 disaccharides, were identified in raw products and the wine-processed products. The results of determination showed that the contents of fructose, glucose, mannose and sucrose in P. cyrtonema rhizoma increased after wine-processing, and their increases were 4.54, 1.51, 2.93, 3.66 times, respectively. ConclusionAfter processing, the increase of aromatic flavor of P. cyrtonema rhizoma may be related to the increase of the contents of aldehydes such as 2-methylbutyraldehyde and isovaleraldehyde, while the decrease of raw flavor may be related to the decrease of the contents of volatile components such as hexanal and hexanoic acid, the increase of sweet flavor may be related to the increase of the contents of monosaccharides and oligosaccharides such as fructose and sucrose.

Tianxiong has been used as a Chinese medicinal in China for thousands of years, and the earliest record can be traced back to the Shennong's Classic of Materia Medica. It is effective in dispersing wind, dissipating cold, and replenishing fire to streng-then yang. To clarify the origin of Tianxiong, the present herbalogical study reviewed the ancient and modern literature from the origin, processing, and clinical efficacy. Before the Tang Dynasty, although the description of Tianxiong was quite superficial, an apparent difference between Tianxiong and Fuzi was recognized. In the Tang and Song Dynasties, Tianxiong and Fuzi were mistakenly recognized to be prepared from a same plant since their raw materials came from artificial cultivation. Medical literature in the Ming and Qing Dynasties mostly followed the previous records, with the origin of Tianxiong remaining controversial. There were three mainstream views about the origin of Tianxiong according the ancient medical books. First, Tianxiong was a kind of Aconiti Radix(Chuanwu) without attachment of Fuzi. Second, Tianxiong was the large Fuzi. Third, Tianxiong derived from Aconiti Kusnezoffii Radix(Caowu) about 10 cm in length. By contrast, Fuzi in a large size was simply regarded as Tianxiong in modern times. The processing methods were diversified in the ancient times, and the fire-processing was continuously applied. With the deepening of the research on the efficacy and detoxification mechanism, more methods were discovered, such as processing with ginger juice, child's urine and alcohol. As for modern times, the processing of Tianxiong has not been nearly passed down. The characteristic processing of Tianxiong only handed down in Sichuan province and Lingnan area, which can be discriminated by the last step. The efficacies of Tianxiong can be directly understood from its literal name, including dispersing wind, dissipating cold, and replenishing fire to assist yang. Nowadays, Tianxiong is mostly used to strengthen yang.

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc. Among them, stir-frying, and stir-frying with the earth scraped from the wall facing east are still used nowadays. The bran stir-frying is the improved version of glutinous rice stir-frying in order to be adaptive to the modern-day situation and the needs of the present. In addition, the ancient shell removal and kernel keeping method are also included in the processing procedures in modern local processing specifications, which are combined with frying to form a new method named "Fazhi" processing( "Fazhi" means a processing method of multiple procedures). The 2015 edition of Chinese Pharmacopoeia records that Coicis Semen is helpful to clear dampness and promote diuresis, strengthen the spleen and prevent diarrhea, eliminate impediment, discharge pus, resolve toxin and a mass, etc., which are consistent with those contained in ancient monographs on materia medica. After the "Fazhi" processing, the cold nature of Coicis Semen has been removed and its nature,flavour and meridian tropism have been changed, so its application scopes expanded. The results of this study clearly traced the history of the collecting and proces-sing of Coicis Semen, summarized the nature, flavour and efficacy of Coicis Semen contained in both ancient and modern literature, and provided a historical basis for the standardization of the subsequent processing technology of Coicis Semen, the clinical application of various processed products, and the further development and utilization of medicinal materials.
