The 95% ethanol extract of Stephania hernandifolia was isolated and purified by column chromatography on silica gel and Sephadex LH-20, RP-18 medium-pressure liquid chromatography, and semi-preparative high performance liquid chromatography. The chemical structures of the compounds were identified by NMR and high-resolution mass spectrometry. Four alkaloids were isolated and identified as(-)-8-oxo-2,3,4,10,11-pentamethoxyberberine(1),(-)-8-oxo-11-hydroxy-2,3,4,10-tetramethoxyberberine(2), N-trans-feruloyl tyramine(3), and N-cis-feruloyl tyramine(4). Compounds 1 and 2 were new protoberberine alkaloids, while compounds 3 and 4 were amide alkaloids. All the four compounds were separated from this plant for the first time. The inhibitory activities of compounds 1, 3, and 4 against α-glycosidase were measured by the enzymatic reaction in vitro with 4-nitrophenyl-α-D-glucopyranoside(PNPG) as the substrate. Compounds 3 and 4 showed inhibitory activities against α-glucosidase, with median inhibition concentration(IC_(50)) values of(7.09±0.42) and(31.25±1.14) μmol·L~(-1), respectively.

OBJECTIVE:
To explore clinical effects of bone setting manipulation combined with pry reduction and Kirschner needle internal fixation in treating SandersⅡ-Ⅲ calcaneal fracture.
METHODS:
Clinical data of 52 patients with types Sanders Ⅱand Ⅲ calcaneal fracture (foot) treated with bone-setting manipulation combined with pry reduction and Kirscher needle internal fixation from July 2017 to July 2019 were retrospectively analyzed, including 43 males and 9 females, aged from 31 to 72 years old with an average of (50.83±10.48) years old; 15 patients with Sanders typeⅡ and 37 patients with Sanders type Ⅲ. The changes of Bühler angle, Gissane angle, calcaneus width and calcaneus height before operation and 24 months after operation were compared, and Maryland foot function score was performed to evaluate clinical effects.
RESULTS:
All patients were followed up from 24 to 60 months with an average of (41.50±9.86)months. The fracture healed normally and the healing time was (11.00±0.95) weeks. Bühler angle, Gissane angle, calcaneal bone width and calcaneal bone height were increased from (16.37±8.36)°, (96.27±9.62)°, (46.82±4.67) mm, (38.41±3.58) mm before operation to (31.48±8.24)°, (111.62±8.69)°, (42.06±4.83) mm, (44.21±3.82) mm at 24 months after operation, and the difference were statistically significant (P<0.01). Postoperative Maryland score at 24 months was (93.04±8.83), 40 patients got excellent result, 7 good and 5 fair.
CONCLUSION
Orthopedic manipulation combined with percutaneous reduction and Kirschner wire internal fixation could significantly improve Bühler angle, Gissane angle, width, and height of Sanders typeⅡ and Ⅲ calcaneal fractures, and the curative effect is satisfactory.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.

Objective:To examine the clinical outcomes of patients undergoing total thoracoscopic aortic-mitral double-valve replacement.Methods:This is a retrospective case series study. The clinical data of 50 patients who underwent double-valve replacement under a total thoracoscopic two-port approach from November 2021 to August 2022 in the Department of Cardiovascular Surgery, Fujian Medical University Union Hospital were retrospectively analyzed. There were 32 males and 18 females, with an age of (55.3±8.8) years (range: 21 to 62 years). Among them, 36 cases had rheumatic heart disease and 14 cases had infective endocarditis. The 3 rd intercostal space between the right anterior axillary line and the midclavicular line was selected as the main operating hole, the total thoracoscopic double-valve replacement were successfully carried out. Baseline data, intraoperative information, surgical outcomes, and postoperative complications were collected for all patients. Results:The cardiopulmonary bypass time was (168.2±30.9) minutes (range: 125 to 187 minutes), the aortic cross-clamping time was (118.8±16.5) minutes (range: 96 to 147 minutes). Five patients received bioprosthetic valves, and 45 received mechanical prosthetic valves. Postoperative mechanical ventilation lasted (9.6±3.4) hours (range: 5.1 to 14.2 hours), the ICU stay was (24.8±7.3) hours (range: 16.3 to 30.1 hours), and the postoperative hospital stay was (6.5±1.2) days (range: 5.0 to 8.0 days). Four patients received red blood cell transfusions of (2.7±0.9) units (range: 2 to 4 units), and the postoperative chest drainage volume was (222.1±56.3) ml (range: 175 to 289 ml). No deaths occurred intraoperatively or in the early postoperative period. One patient required reoperation due to bleeding in the aortic incision. Three patients had mild to moderate paravalvular leakage around the prosthetic aortic valve, with no cases of third-degree atrioventricular block or conversions to median sternotomy.Conclusions:The early outcomes of total thoracoscopic double valve replacement surgery are satisfactory, demonstrating safety and efficacy. This surgical approach expands the scope of total thoracoscopic cardiac surgery, which warrants further investigation and research.
