Objective To compare the clinical efficacy of neuroendoscope-assisted evacuation and navigation-assisted puncture drainage in treating thalamic hemorrhage breaking into the ventricle. Methods A retrospective analysis was conducted on the clinical data of 93 patients with thalamic hemorrhage breaking into the ventricle at Taihe Hospital of Wannan Medical College between January 2022 and February 2024. The patients received neuroendoscope-assisted removal of thalamic hematoma combined with contralateral extraventricular drainage (n＝44, neuroendoscope group) and navigation-assisted thalamic hematoma puncture drainage combined with contralateral extraventricular drainage (n＝49, navigation group), respectively. The treatment efficacy, surgical situation, and prognosis between the two groups were compared. Results The neuroendoscope group had longer operation duration, more intraoperative blood loss, higher hospitalization costs than the navigation group (P＜0.05). The neuroendoscope group had higher hematoma clearance rate 3rd after surgery and shorter length of stay than the navigation group (P＜0.05). There was no significant difference in the incidence of intracranial infection after surgery between the two groups. The neuroendoscope group had higher Glasgow coma scale (GCS) score at 1 week after surgery and Glasgow outcome scale (GOS) score at 3 months after surgery (P＜0.01). Conclusions Compared with navigation-assisted puncture, neuroendoscope-assisted evacuation can improve the thalamic hemorrhage clearance rate, shorten the length of stay, and improve the prognosis of patients.

OBJECTIVE To analyze the trends of potentially inappropriate medication （PIM） among elderly cancer patients in the context of the diagnosis-related groups（DRG）-based medical insurance payment reform.METHODS Relevant data were extracted for elderly inpatients with cancer at a Grade-A Level-Ⅲ hospital from January 2018 to March 2025. Prescribed medications were screened for PIM using the 2024 Chinese Criteria for Identifying PIM in the Elderly and the US 2023 Beers Criteria， and consistency was evaluated. An interrupted time-series （ITS） model was established， with the period from January 2018 to December 2020 designated as the pre-implementation group， and January 2021 to March 2025 as the post-implementation group. The study analyzed the impact of the medical insurance DRG payment reform on per capita hospitalization costs， per capita length of stay， average number of medication specifications per patient， overall PIM incidence， and PIM incidences for target medications among elderly cancer inpatients. To eliminate the influence of baseline characteristics （age， sex）， propensity score matching（PSM） was further applied， followed by an ITS model analysis to assess the impact of the DRG payment reform on the overall PIM incidence among elderly cancer inpatients.RESULTS A total of 16 910 elderly cancer inpatients were included （6 552 in the pre-implementation group， and 10 358 in the post-implementation group）； PIMs occurred in 9 138 patients， with an incidence of 54.04%. PIMs involved 198 types of medications， among which six target medications （including Diclofenac sodium enteric capsules and Oxycodone hydrochloride sustained-release tablets）， exhibited a higher average PIM incidence or a significant trend change； the Kappa value for the consistency evaluation of the assessments by two pharmacists was 0.931 （ P ＜0.001） . After the implementation of DRG， the per capita hospitalization costs showed a downward trend of 103.501 yuan per month （ P ＜0.001）； the per capita length of stay showed a slight upward trend （increasing by 0.052 days per month， P ＝0.017）， but the actual slope （－0.036） was less than 0； there was no significant change in the average number of medication specifications per patient （ P ＝0.193）. The DRG payment reform under medical insurance can produce statistically significant instantaneous impact effects on the PIM incidences among users of Diclofenac sodium enteric capsules， Doxofylline injection， and Cimetidine injection （ P values of 0.041， 0.001， and 0.036， respectively）， a statistically significant long-term trend effect on the PIM incidences among users of Oxycodone hydrochloride sustained-release tablets （ P ＝0.008）， and statistically significant instantaneous shock and long-term trend effects on the PIM incidences among users of Spironolactone tablets （ P values of 0.035 and 0.031） and Aminophylline injection （ P values of 0.009 and 0.031）. Regardless of whether PSM was applied， the overall PIM incidence among patients showed a slight upward trend [an increase of 0.228% per month， P ＝0.001 （without PSM）， or an increase of 0.239% per month， P ＜0.001 （after PSM）].CONCLUSIONS Following the implementation of the DRG payment reform for medical insurance， the per capita hospitalization cost for elderly inpatients with cancer decreases significantly， while the decline in the per capita length of stay slows. The overall PIM incidence shows a slight upward trend， and the trends in PIM incidence vary across different drug formulations.

ObjectiveTo explore the effects of different embolic materials for preoperative transarterial embolization （TAE） on surgical resections of sizeable （＞3 cm） Shamblin Ⅱ/Ⅲ carotid body tumors （CBTs） MethodsThis study retrospectively analyzed the data of patients with Shamblin type Ⅱ/Ⅲ carotid body tumors >3 cm in size who underwent TAE at our hospital between January 2010 and August 2025. Based on the adopted embolic agents， the patients were divided into two groups： temporary embolization group （TEG） and permanent embolization group （PEG）. General clinical data， periprocedural details， and postoperative outcomes were collected and compared between the two groups. ResultsA total of 50 patients with 50 lesions were included （n=25 in the TEG and n=25 in PEG group）. Tumor sizes were comparable between the two groups ［（41.22 vs. 42.13） mm， P=0.989］. For the TEG compared with PEG， intraoperative blood loss was （388.19 vs. 155.90） mL （P＜0.001） and operative time was （254.01 vs. 162.22） mins （P=0.007）. The intraoperative vascular reconstruction rate was 16% vs. 12% （P=0.684）， and the complication rate was 36% vs. 12% （P=0.047） in the TEG and PEG. ConclusionsOur results indicate that the use of permanent embolic agents during TAE is optimal. These agents are superior to temporary embolic agents in terms of intraoperative blood loss， operative time， and improved surgical field visualization， which thereby facilitate the surgical resection of Shamblin type Ⅱ/Ⅲ CBTs while reducing postoperative complications.

Objective: To explore the effect of HIF-1α on osteogenic-angiogenic coupling response in bone mesenchymal stem cells (BMSCs) and provide new concepts for engineered bone tissue in vitro. Methods: With the approval of the hospital’s experimental animal ethics committee, BMSCs were harvested from Wistar rats. The lentivirus carrying hypoxia-inducible factor-1α (HIF-1α) and empty lentivirus were stably transfected into the third generations of BMSCs to form LV-HIF-1α-BMSCs and LV-BMSCs. Meanwhile, BMSCs without transfection of lentivirus were used as a blank control. Then, the effect of HIF-1α transfection was verified by qPCR and Western Blot. LV-HIF-1α-BMSCs were induced to differentiate into endothelium-like cells (iECs). The morphology was observed by optical microscopy, the differentiation rate was detected by cellular flow CD31, and the Transwell test was used to detect the migration ability. At the same time, LV-HIF-1α-BMSCs and LV-BMSCs were continuously cultured to form osteogenic cell sheets (OCTs), which were stained by alkaline phosphatase on day 14 and alizarin red staining on day 21, and counted for mineralization capacity. Finally, iECs were implanted into OCTs to form prevascularized osteogenic cell sheets (P-OCTs), immunofluorescence CD31 was performed to detect the formation of vascular networks, and the results were recorded on days 1, 3, 7, and 14. Meanwhile, osteopontin (OPN) and osteocalcin (OCN) were detected by western blot to verify their ability for osteogenic differentiation on days 1, 7, and 14. Results: The optimal multiplicity of infection (MOI) for lentiviral transfection was 30, and the transfection efficiency was >80%. The results of qPCR and western blot showed that compared with the LV-BMSCs group and BMSCs group, the LV-HIF-1α-BMSCs group had stable and high expressions of HIF-1α (P<0.05). LV-HIF-1α-BMSCs showed an enhanced ability to differentiate into endothelial cells, with a differentiation rate as high as 91.81%. Transwell assay verified that HIF-1α could recruit iECs in vitro. Alkaline phosphatase staining and alizarin red staining confirmed that OCTs formed by LV-HIF-1α-BMSCs had a statistically significant osteogenic differentiation ability compared with LV -BMSCs control group (P<0.05). When iECs were implanted into the LV-HIF-1α-BMSCs group OCTs to form P-OCTs, iECs substantially proliferated and rapidly fused, and formation of the progressive lumen was revealed by immunofluorescent CD31 staining. The expressions of OPN and OCN were significantly enhanced compared with those of the LV-BMSCs control group; OCN was the highest on day 7, and OPN was the highest on day 1 (P<0.05). Conclusion BMSCs transfected by HIF-1α have good osteogenic-angiogenic effect after induction and differentiation, which provides experimental foundation for optimizing the construction of three-dimensional prevascularized bone tissue.

BACKGROUND: Endoscopic sphincterotomy (EST) is widely used to treat common bile duct stones (CBDS); however, long-term studies have revealed the increasing incidence of recurrent CBDS after EST. Loss of sphincter of Oddi function after EST was the main cause of recurrent CBDS. Reparation of the sphincter of Oddi is therefore crucial. This study aims to investigate the effectiveness and safety of endoclip papilloplasty (ECPP) for repairing the sphincter of Oddi and elucidate its mechanism. METHODS: Eight healthy Bama minipigs were randomly divided into the EST group and the ECPP group at a 1:1 ratio, and bile samples were collected before endoscopy and 6 months later. All minipigs underwent transabdominal biliary ultrasonography for the diagnosis of cholelithiasis 6 months after endoscopy. The biliary microbiota composition and alpha and beta diversity were analyzed by 16S ribosomal RNA gene sequencing. Differential metabolites were analyzed by bile acid metabolomics to explore the predictive indicators of cholelithiasis. RESULTS: Three minipigs were diagnosed with cholelithiasis in the EST group, while none in the ECPP group showed cholelithiasis. The biliary Firmicutes/Bacteroidota (F/B) ratio was increased after EST and decreased after ECPP. The Chao1 and observed species index significantly decreased 6 months after EST ( P  = 0.017 and 0.018, respectively); however, the biliary α-diversity was similar before and 6 months after ECPP. The β-diversity significantly differed in the EST group before and 6 months after EST, as well as in the ECPP group before and 6 months after ECPP (analysis of similarities [ANOSIM]: R  = 0.917, P  = 0.040; R  = 0.740, P  = 0.035; respectively). Glycolithocholic acid (GLCA) and taurolithocholic acid (TLCA) accumulated in bile 6 months after EST. CONCLUSIONS ECPP has less impact on the biliary microenvironment than EST and prevents duodenobiliary reflux by repairing the sphincter of Oddi. The bile levels of GLCA and TLCA may be used to predict the risk of cholelithiasis.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

Cancer represents a significant disease that profoundly impacts human health and longevity. Projections indicate a 47% increase in the global cancer burden by 2040 compared to 2020, accompanied by a further rise in the associated economic burden. Consequently, there is an urgent need to discover and develop new alternative drugs to mitigate the global impact of cancer. Natural products (NPs) play a crucial role in the identification and development of anticancer therapeutics. This study identified ustusolate E (UE) and its analog 11α-hydroxy-ustusolate E (HUE) from strain Aspergilluscalidoustus TJ403-EL05, and examined their antitumor activities and mechanisms of action. The findings demonstrate that both compounds significantly inhibited the proliferation and colony formation of AGS (human gastric cancer cells) and 786-O (human renal clear cell carcinoma cells), induced irreversible DNA damage, blocked the cell cycle at the G₂/M phase, and further induced apoptosis in tumor cells. To the best of the authors' knowledge, this is the first report on the anticancer effects of UE and HUE and their underlying mechanisms. The present study suggests that HUE and UE could serve as lead compounds for the development of novel anticancer drugs.

Five novel nor-eremophilane-type sesquiterpenoids, peniroqueforins E-H and J (1-4 and 7), two new eremophilane-type sesquiterpenoids, peniroqueforins I and K (5 and 8), and a new eudesmane-type sesquiterpenoid, peniroqueforin L (9), along with four known compounds (6 and 10-12), were isolated and characterized from fungus Penicillium roqueforti (P. roqueforti). The structures and absolute configurations of these compounds were determined through comprehensive spectroscopic analyses, electronic circular dichroism (ECD) data analyses, and single-crystal X-ray diffraction methods. The anti-multi-drug resistance (MDR) cancer activity of these compounds was evaluated using SW620/Ad300 cells. Notably, the half maximal inhibitory concentration (IC₅₀) value of paclitaxel (PTX) combined with 1 in SW620/Ad300 cells was 50.36 nmol·L^-1, which was 65-fold more potent than PTX alone (IC₅₀ 3.26 μmol·L^-1). Subsequent molecular docking studies revealed an affinity between compound 1 and P-glycoprotein (P-gp), suggesting that this nor-eremophilane-type sesquiterpenoid (1) could serve as a potential lead for MDR reversal in cancer cells through P-gp inhibition.
