OBJECTIVE To compare the antihypertensive efficacy of sacubitril/valsartan versus benazepril in patients with perimenopausal hypertension， as well as their impacts on ventricular remodeling and inflammatory fibrosis. METHODS A total of 206 perimenopausal hypertensive patients in our hospital from January 1， 2023 to December 30， 2024 were retrospectively included.These patients were enrolled and divided into benazepril group （105 cases） and sacubitril/valsartan group （101 cases）. Benazepril group received Benazepril hydrochloride tablet， and sacubitril/valsartan group received Sacubitril valsartan sodium tablet. All patients were treated for 6 months. The blood pressure（systolic blood pressure and diastolic blood pressure） and blood pressure control status before and after treatment， echocardiographic indicators （left ventricular ejection fraction， left ventricular mass index， relative wall thickness， and early-diastolic peak transmitral flow velocity/early-diastolic peak velocity of the mitral annulus）， inflammatory fibrosis related indicators（high-sensitivity C-reactive protein，ratio of monocytes to lymphocytes，and ratio of neutrophils to lymphocytes）， as well as the occurrence of adverse reactions（hypotension，hyperkalemia，and angioedema） were observed in both groups before and after treatment. RESULTS The blood pressure control rate was significantly higher in the sacubitril/valsartan group than in benazepril group （ P ＜0.05）. After treatment， the blood pressure， echocardiographic indicators（except for left ventricular ejection fraction） ，and inflammatory fibrosis related indicators were significantly lower than those before treatment within the same group， and the sacubitril/valsartan group were significantly lower than the benazepril group （ P ＜0.05）. There were no statistically significant differences in the incidence of hypotension， hyperkalemia， angioedema， and overall adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared with benazepril， sacubitril/valsartan provides superior blood-pressure control， reverses ventricular remodeling， attenuates inflammatory fibrosis in perimenopausal hypertensive patients， while maintaining a similar safety profile.

Objective To explore the efficiency improvement in segmenting neural network with the application of Transformer + U-Net artificial intelligence (AI) and modeling with the application of Python scripts in three-dimensional (3D) printing brachytherapy. Methods A Transformer + U-Net AI neural network model was constructed, and Adam optimizer was used to ensure rapid gradient descent. Computed tomography or magnetic resonance imaging data of patients were standardized and processed as self-made data sets. The training set was used to train AI and the optimal result weight parameters were saved. The test set was used to evaluate the AI ability. Python programming language was used to write an automated script to obtain the output segmentation image and convert it to the STL file for import. The source applicator and needle could be automatically modeled. The time of automatic segmentation and modeling and the time of manual segmentation and modeling were entered by two people, and the difference was verified by paired t-test. Results Dice similarity coefficient (DSC), mean intersection over union (MIOU), and Hausdorff distance (HD95) were used for evaluation. DSC was 0.9341, MIOU was 0.8762, and mean HD95 was 2.516. The mean time of manual segmentation was 1187 s, and the mean time of AI segmentation was 145 s (P < 0.01). The mean time of manual modeling was 321 s, and the mean time of modeling with Python automated scripts was 18 s (P < 0.01). Conclusion The application of Transformer + U-Net automatic segmentation and Python automated scripts can effectively improve work efficiency in the 3D printing brachytherapy for cervical cancer.

AIM: To review and summarize the current research and achievements in the field of diabetic cataract, with the aim of better identifying research hotspots and trends in this area.METHODS: Based on the relevant literature retrieved from the China National Knowledge Infrastructure, Web of Science databases, and Pubmed, a bibliometric analysis of the diabetic cataract was conducted by means of Microsoft Office Excel 2017 and CiteSpace 6.3R2. Research hotspots were subsequently synthesized after visualizations of author/country collaborations, co-citation networks of highly cited literature, keyword clustering, and emergence.RESULTS: A total of 815 Chinese and 572 English publications were finally included. Overall, this field had maintained substantial scholarly attention globally, though publications had progressively decreased since 2018. While inter-institutional collaboration in this area remained limited, a multinational collaborative network had emerged with the People's Republic of China, the United States of America, the United Kingdom, and the Kingdom of Spain as central hubs. Core research priorities in diabetic cataract consistently encompassed surgical and pharmacological interventions, pathogenesis, associated ocular/systemic complications; while international and domestic research contents aligned fundamentally in these domains, but the domestic research was unique in nursing interventions and herbal medicine-based interventions. Recent analytical trends revealed that Chinese investigations prioritized the pathogenic mechanisms of diabetic cataract, whereas international efforts concentrated on clinical therapeutics.CONCLUSION: This bibliometric analysis of diabetic cataract research literature(2000-2024)synthesizes the current advancements, research priorities, and scholarly contributions in the field, and intuitively demonstrates significant academic merit and clinical relevance, which can provide evidence-based guidance for the future research trajectories.

OBJECTIVE To explore the practice pathway and evaluate the effectiveness of the resident pharmacists stationed in the Drug Clinical Trial Institution Office （hereinafter referred to as the “GCP resident pharmacist”） in the management of dermatological drug clinical trials. METHODS The practical approach of GCP resident pharmacists participating in dermatological drug clinical trials at our hospital was introduced. A retrospective analysis was conducted on the data of dermatological drug clinical trials from 2021 to 2024， comparing efficiency and quality indicators between dermatological clinical trials and those of other specialties. RESULTS With the involvement of our hospital’s GCP resident pharmacists throughout, the process for dermatology drug clinical trials was constructed and optimized， a dedicated quality control system was established， and the acceleration strategy for subject enrollment was optimized. The number of dermatological drug clinical trials at our hospital showed a compound annual growth rate of 69.56% from 2021 to 2023. In terms of efficiency indicators， the approval waiting time for dermatological drug clinical trials was （12.31±4.99） days， which was significantly shorter than that of other specialties （[ 19.68±6.09） days， P＜0.05]. Regarding quality indicators， the enrollment rate for dermatological drug clinical trials was 75.71%（50.00%，114.48%）， which was significantly higher than that of other specialties [51.00%（25.00%，174.17%）， P＜0.05]. The numbers of first quality control issues （[ 8.31±3.25）items vs.（ 11.68±4.49）items] and protocol deviations [5.5（2.0，11.0）times vs. 11.0（5.5，17.5）times] were significantly lower than those of other specialties （P＜0.05）. CONCLUSIONS GCP resident pharmacists significantly enhance the overall efficiency of dermatological drug clinical trials， playing a crucial role in ensuring the reliability and authenticity of drug clinical trials， as well as safeguarding the rights and safety of trial subjects.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

OBJECTIVES: To explore the association of the expression of WW domain-containing ubiquitin E3 ligase 1 (WWP1) with immune infiltration in tumor microenvironment (TME) of ovarian cancer. METHODS: Ovarian cancer patient data from The Cancer Genome Atlas (TCGA) were used to analyze the association of WWP1 expression with patient prognosis. TISCH2 was utilized to analyze the changes in immune cell subtypes in TME of metastatic tumor and after chemotherapy. The impact of WWP1 on immune cell infiltration, somatic copy number alterations of WWP1 and evolution of immune cell subtypes was evaluated using TIMER and TIGER pseudo-time analysis. A deep learning model was used to analyze TCGA pathological images to investigate the effect of WWP1 on TME of ovarian cancer. RNA-seq analysis was conducted to identify the differentially expressed genes in WWP1-overexpressing SKOV3 cells and validate immune infiltration. Multicolor immunofluorescence assay was used to analyze the immune markers in SKOV3 and SKOV3/DDP cell xenografts in nude mice. RESULTS: The patients with high WWP1 expression levels had significantly lower overall survival rate (P=0.0012). High WWP1 expression levels and Stage IV disease were both associated with a poor prognosis (P<0.05). In metastatic ovarian cancer or after chemotherapy, the percentages of malignant tumor cells and tumor-associated fibroblasts increased in the TME, accompanied by elevated WWP1 levels. WWP1 expression level was positively correlated with pro-tumorigenic immunosuppressive cells (r=0.1323-0.3955, P<0.05) and negatively with tumor-inhibiting immune cells (r=-0.1949- -0.1333, P<0.05). Specific copy number alterations of WWP1 also influenced CD8⁺ T cell percentage and neutrophil infiltration levels in the TME. RNA-seq analysis of WWP1-overexpressing SKOV3 cells and immunofluorescence assay of the tumor-bearing mice yielded findings consistent with those of bioinformatics analysis. CONCLUSIONS WWP1 may serve as a prognostic biomarker and a potential target for immune regulation in the TME of ovarian cancer.

OBJECTIVE: To investigate the effect of electroacupuncture pretreatment on the quality of recovery in the patients undergoing laparoscopic gastrointestinal surgery. METHODS: Sixty patients for elective laparoscopic resection of gastrointestinal tumors under general anesthesia were randomly assigned to either an observation group or a control group, with 30 patients in each group. In the control group, the routine inhalation-intravenous combined general anesthesia was adopted. On the basis of the control group, in the observation group, 30 min before anesthesia induction, electroacupuncture was applied to bilateral Neiguan (PC 6) and Neimadian (Extra) for 30 min, using disperse-dense wave and at 2 Hz/100 Hz. The recovery time of spontaneous breathing, awakening time, extubation time, and the post-anesthesia care unit (PACU) stay time were compared between the two groups. Mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO₂) were recorded at multiple time points: before electroacupuncture (T0), before extubation (T1), immediately after extubation (T2), 5 minutes (T3) and 10 minutes (T4) after extubation, and upon discharge from PACU (T5). The visual analogue scale (VAS) score for pain and Ramsay sedation score at T3, T4 and T5 were observed; and the incidence of agitation, nausea and vomiting at T5 was evaluated in the two groups. At T0 and T5, the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and cortisol were determined in the two groups. RESULTS: In the observation group, the recovery time of spontaneous breathing, awakening time, extubation time, and PACU stay time were shorter (P<0.001), MAP and HR at T2 were lower (P<0.01, P<0.05), the VAS scores for pain at T3, T4, and T5 dropped (P<0.001, P<0.01), and the Ramsay sedation score at T3 reduced (P<0.05) compared with those in the control group. The incidence of nausea and vomiting was lower in the observation group when compared with that in the control group (P<0.05). In comparison with the indexes at T0, the serum levels of TNF-α, IL-6, and cortisol increased at T5 in both groups (P<0.01); and these indexes at T5 in the observation group were lower than those in the control group (P<0.01, P<0.05). CONCLUSION Electroacupuncture pretreatment can enhance the quality of recovery in the patients undergoing laparoscopic gastrointestinal tumor surgery, shorten the time for spontaneous breathing recovery, awakening, extubation and PACU stay, and attenuate postoperative pain and stress response.

The quality of moxa is an important factor affecting moxibustion therapy, and traditionally, 3-year moxa is considered optimal, although scientific data are lacking. This study focused on 1-year and 3-year moxa from Artemisia stolonifera and A. argyi(leaf-to-moxa ratio of 10∶1) as research objects. Scanning electron microscopy(SEM), Van Soest method, and simultaneous thermal analysis were used to investigate the differences in the combustion heat quality of 1-year and 3-year moxa and their influencing factors. The results showed that the combustion of A. stolonifera moxa exhibited a balanced heat release pattern. The 3-year moxa released a concentrated heat of 9 998.84 mJ·mg~(-1)(accounting for 54% of the total heat release) in the temperature range of 140-302 ℃, with a heat production efficiency of 122 mW·mg~(-1). It further released 7 512.51 mJ·mg~(-1)(accounting for 41% of the total heat release) in the temperature range of 302-519 ℃. The combustion of A. argyi moxa showed a rapid heat release pattern. The 3-year moxa released a heat of 16 695.28 mJ·mg~(-1)(accounting for 70% of the total heat release) in the temperature range of 140-311 ℃, with an instantaneous power output of 218 mW·mg~(-1). It further released 5 996.95 mJ·mg~(-1)(accounting for 25% of the total heat release) in the temperature range of 311-483 ℃. Combustion parameters such as-R_p,-R_v, D_i, C, and D_b indicated that the combustion heat quality of 3-year moxa was superior to that of 1-year moxa. It exhibited greater combustion heat, heat production efficiency, flammability, mild and sustained burning, and higher instantaneous combustion efficiency. This study utilized scientific data to demonstrate that A. stolonifera could be used as excellent moxa, and the quality of 3-year moxa surpassed that of 1-year moxa. The research results provide a scientific basis for the in-depth development of A. stolonifera moxa and the improvement of moxa quality standards.
