Objective To research the effects of drought stress on activity of key enzyme in saikosaponin biosynthesis and saponins content in Bupleurum chinense; To reveal response of Bupleurum chinense to drought stress from protein level. Methods Bupleurum chinense was cultivated in potted water control experiment with 70%–80%, 60%–70%, 40%–50% and 20%–30% saturated soil water contents. The enzyme activities of 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGR), isoprenyl-based coke (IPPI), farnesyl pyrophosphate synthase (FPS) and β-carotenoid synthase (β-AS) of six months and one year old Bupleurum chinense were measured. The contents of saikosaponins a and d in samples of different soil water contents were determined by HPLC. Results When the saturated moisture was 40%–50%, the enzymatic activities of HMGR, IPPI, FPS and β-AS were the highest, followed by saturated moisture 60%–70%、70%–80% and 20%–30%. The trend of saikosaponin was similar to that of the activity of key enzyme. Conclusion 40%–50% soil saturated water content can significantly increase the activity of the key enzymes in the saikosaponin synthesis pathway. The saponin content and enzyme activity show a significant positive correlation, indicating that under drought stress, Bupleurum chinense regulates the synthesis of saikosaponin by regulating the key enzyme activity of saikosaponin synthesis pathway to respond drought stress.

Objective: Network pharmacology combines drug and disease targets with biological information networks based on the integrity and systematicness of the interactions between drugs and disease targets. This study aims to explore the molecular basis of Hanshi Zufei formula for treatment of COVID-19 based on network pharmacology and molecular docking techniques. Methods: Using TCMSP, the chemical constituents and molecular targets of Atractylodis Rhizoma, Citri Reticulatae Pericarpium, Magnoliae Officinalis Cortex, Pogostemonis Herba, Tsaoko Fructus, Ephedrae Herba, Notopterygii Rhizoma et Radix, Zingiberis Rhizoma Recens, and Arecae Semen were investigated. The predicted targets of novel coronavirus were screened using the NCBI and GeneCards databases. To further screen the drug-disease core targets network, the corresponding target proteins were queried using multiple databases (Biogrid, DIP, and HPRD), a protein interaction network graph was constructed, and the network topology was analyzed. The molecular docking studies were also performed between the network's top 15 compounds and the coronavirus (SARS-CoV-2) 3CL hydrolytic enzyme and angiotensin conversion enzyme II (ACE2). Results: The herb-active ingredient-target network contained nine drugs, 86 compounds, and 49 drug-disease targets. Gene ontology (GO) enrichment analysis resulted in 1566 GO items (P < 0.05), among which 1438 were biological process items, 35 were cell composition items, and 93 were molecular function items. Fourteen signal pathways were obtained by enrichment screening of the KEGG pathway database (P < 0.05). The molecular docking results showed that the affinity of the core active compounds with the SARS-CoV-2 3CL hydrolase was better than for the other compounds. Conclusion: Several core compounds can regulate multiple signaling pathways by binding with 3CL hydrolase and ACE2, which might contribute to the treatment of COVID-19.

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.
