Object To study the chemical constituents from the fruits of Juniperus formosana Hayata. Methods The compounds were isolated and purified on liquid-liquid, silica gel, and aluminium oxide column chromatography, their structures were identified by spectroscopic methods, such as GC-MS, 1H-NMR, and 13C-NMR, especially 2D-NMR. Results Two new oxygenated diterpenoids, named labdatriene (Ⅰ) and labdadiene (Ⅱ), were isolated from the ethyl acetate extract. Their structures were determined to be 19-carboxy-8(17)-13(16)-14-labdatriene and 15, 19-dihydroxyl-8(17)-13(E)-labdadiene, respectively. Conclusion Compounds Ⅰ and Ⅱ are new diterpenoids.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.
