ObjectiveTo reveal the changing pattern of fungal communities and isoflavone content during the fermentation of Sojae Semen Praeparatum. MethodsInternal transcribed spacer (ITS) amplicon sequencing was used to analyze the changes in fungal communities during the fermentation. High-performance liquid chromatography (HPLC) was employed to determine the composition and content of isoflavones. Spearman correlation analysis was conducted to identify fungal communities positively correlated with isoflavone content. ResultsDuring the fermentation of Sojae Semen Praeparatum, the abundance of Penicillium continued to increase and became the dominant genus from the "yellow cladding" to the early "secondary fermentation" stage (9 days). However, in the mid-to-late "secondary fermentation" stage (12-21 days), the abundance of Penicillium decreased, while the abundance of Barnettozyma increased rapidly, becoming the dominant genus during the later stages (18-21 days). Alpha diversity analyses showed that fungal diversity was higher in the "secondary fermentation" stage than in the "yellow cladding" stage. Beta diversity analyses showed greater variability in fungal communities during the "yellow cladding" stage, with relatively stable fungal communities during the "secondary fermentation" stage. The aglycone isoflavone content exhibited a gradual increase, rising from 5.56% at the start of fermentation to 96.84% by the end. In contrast, the glucoside isoflavone content experienced a corresponding decline, decreasing from 94.44% to 3.16%. Spearman analysis showed that Penicillium, Barnettozyma, and Ilyonectria were positively correlated with the contents of daidzein, glycitein, and genistein, and promoted the conversion of isoflavones from glucoside to aglycone forms. ConclusionThe fungal communities of Penicillium, Barnettozyma, and Ilyonectria promote the conversion of isoflavones from glucoside to aglycone forms during the fermentation of Sojae Semen Praeparatum. The findings provide an important reference for improving the scalability and quality of Sojae Semen Praeparatu fermentation.

By consulting ancient and modern literature, the herbal textual research of Farfarae Flos has been conducted to verify the name, origin, producing area, quality evaluation, harvesting and processing methods, so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research, the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing(《神农本草经》), and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara, in addition, the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar, and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei, Gansu, Shaanxi are the authentic producing areas with the good quality products. Since modern times, its quality is summarized as big, fat, purple-red color, no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty, and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results, it is suggested that the dried flower buds of T. farfara, a Compositae plant, should be selected for the development of famous classical formulas containing Farfarae Flos, and the corresponding processed products should be selected according to the specific processing requirements of the formulas, and raw products are recommended for medicinal use without indicating processing requirements.

By reviewing the ancient and modern literature, the name, origin, scientific name evolution, place of origin, quality, harvesting, processing, efficacy and toxicity of Asteris Radix et Rhizoma(ARR) were systematically sorted out, so as to provide reference for the development and utilization of the relevant famous classical formulas. According to textual research, ARR was first contained in Shennong Bencaojing, all generations are Ziwan for its proper name, and there are still aliases such as Ziyuan, Ziqian and Xiaobianer. Its mainstream origin in successive generations was Aster tataricus, and there are also Ligularia fischeri and others in local area of use. The medicinal parts of ARR are root and rhizome, but in modern times, the rhizome is mostly used for propagation and cultivation, so some of ARR medicinal materials only have the root without the rhizome. The earliest recorded ancient origin of ARR was now Fangxian(Hubei), Zhengding and Handan(Heibei), then the range of production areas gradually expanded, the mainstream production areas from the Song dynasty to the Ming and Qing dynasties included Hebei, Jiangsu, Anhui, Henan and other places, since modern times, two major producing areas have been formed in Anguo, Hebei province and Bozhou, Anhui province. From the quality evaluation, it is clear that from ancient times, flexible roots and purple color are the best. The ancient harvesting was mainly in lunar February or March, and then dried in the shade, and the modern harvesting is mostly in spring and autumn, and the roots are braided into pigtails and then dried in the sun or dried in the sun after 1-2 d. The ancient and modern processing method of ARR are basically the same, mainly honey processing, there are still methods of frying, steaming, vinegar sizzling, etc. Based on the results, it is recommended that the dried roots and rhizomes of A. tataricus should be used in clinical and the development of related famous classical formulas, and those whose original formulas specify the processing requirements can be processed according to the relevant requirements, while whose processing requirements are not specified should be used in the form of raw products.

Objective:To explore the consistency between modified 12+ X prostate biopsy under transrectal interventional ultrasound and postoperative Gleason score in prostate cancer patients.Methods:A retrospective study was conducted on 312 patients diagnosed with prostate cancer and underwent radical resection at Zhongshan People′s Hospital from January 2020 to December 2022. All patients underwent modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound before surgery. Using the Gleason score of postoperative pathological specimens as the " gold standard", the detection rates of prostate cancer and clinically significant prostate cancer using modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound were compared, and the consistency between the two methods alone or in combination and postoperative Gleason score was compared.Results:Among 312 patients, the positive detection rate of the improved 12+ X puncture biopsy combined with the system puncture biopsy was significantly higher than that of the individual detection (95.51% vs 80.77% vs 76.92%), with a statistically significant difference ( P<0.05). The improved 12+ X puncture biopsy combined with system puncture biopsy showed a clinically significant higher detection rate of prostate cancer in positive patients compared to the two tests alone (94.63% vs 77.78% vs 80.00%), with a statistically significant difference ( P<0.05). There was no statistically significant difference in the detection rate of clinically significant prostate cancer among patients who missed diagnosis, either alone or in combination with biopsy ( P>0.05). The upgrade rate of Gleason score after prostate improvement 12+ X puncture biopsy (25.00%) was significantly lower than that of prostate system puncture (44.17%), which was significantly higher than combined puncture biopsy (11.74%), with a statistically significant difference ( P<0.05). After 312 patients received combined puncture biopsy, urinary retention was found in 14 cases (4.49%), hematuria in 30 cases (9.62%), fever in 28 cases (8.97%), and blood in stool in 18 cases (5.77%). After symptomatic treatment, they basically improved within 3 days after puncture. Conclusions:The combination of modified 12+ X prostate biopsy with systematic biopsy under transrectal interventional ultrasound can improve the detection rate of prostate cancer, and has good consistency with the postoperative Gleason score of prostate cancer patients, which has good clinical application value.

Through reviewing ancient and modern literature, the textual research of Anemarrhenae Rhizoma(AR) has been conducted to verify the name, origin, changes in production areas, quality evaluation, harvesting and processing methods, so as to provide reference for the development and utilization of the famous classical formulas containing AR. Through the herbal textual research, AR was first published in Shennong Bencaojing, and has been used as the proper name for this herb for generations, and the mainstream source of AR used for generations is the rhizome of Anemarrhena asphodeloides. The high-quality production areas that have been revered throughout the ages are Hebei, Shanxi, Shaanxi, Inner Mongolia and Fangshan district of Beijing, etc. In recent times, AR produced in Yixian county of Hebei province(Xiling Zhimu), is better known and is regarded as a very good source. At present, cultivated AR is mainly produced in Yixian county and Anguo of Hebei province, Bozhou of Anhui province and other places. The medicinal parts of AR in ancient and modern times are all rhizomes, and the quality is better if it has thick flesh, hard wood, yellow outer color and white section color. The harvesting time recorded in ancient medical books is usually in lunar February and August, with exposure to dryness, while modern harvesting is spring and autumn. The processing methods of the past dynasties were mainly to remove the hair when using, avoid iron when cutting, process with wine or salt water, while the two main specifications in modern times are raw and salted products. Based on the systematic research, it is recommended that the dried rhizome of A. asphodeloides in the famous classical formulas be used for AR. If the original formula specifies processing requirements, it should be operated according to the requirements, if the processing requirements are not indicated, the raw products can be used as medicine.
