Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P＞0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The study investigated the intrinsic changes in material basis of Angelicae Sinensis Radix during wine processing by headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS), headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), and ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) combined with chemometrics. HS-GC-IMS fingerprints of Angelicae Sinensis Radix before and after wine processing were established to analyze the variation trends of volatile components and characterize volatile small-molecule substances before and after processing. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed for differentiation and difference analysis. A total of 89 volatile components in Angelicae Sinensis Radix were identified by HS-GC-IMS, including 14 unsaturated hydrocarbons, 16 aldehydes, 13 ketones, 9 alcohols, 16 esters, 6 organic acids, and 15 other compounds. HS-SPME-GC-MS detected 118 volatile components, comprising 42 unsaturated hydrocarbons, 11 aromatic compounds, 30 alcohols, 8 alkanes, 6 organic acids, 4 ketones, 7 aldehydes, 5 esters, and 5 other volatile compounds. UPLC-Q-Orbitrap-MS identified 76 non-volatile compounds. PCA revealed distinct clusters of raw and wine-processed Angelicae Sinensis Radix samples across the three detection methods. Both PCA and OPLS-DA effectively discriminated between the two groups, and 145 compounds(VIP>1) were identified as critical markers for evaluating processing quality, including 4-methyl-3-penten-2-one, ethyl 2-methylpentanoate, and 2,4-dimethyl-1,3-dioxolane detected by HS-GC-IMS, angelic acid, β-pinene, and germacrene B detected by HS-SPME-GC-MS, and L-tryptophan, licoricone, and angenomalin detected by UPLC-Q-Orbitrap-MS. In conclusion, the integration of the three detection methods with chemometrics elucidates the differences in the chemical material basis between raw and wine-processed Angelicae Sinensis Radix, providing a scientific foundation for understanding the processing mechanisms and clinical applications of wine-processed Angelicae Sinensis Radix.

BACKGROUND: The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined. METHODS: All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI. RESULTS: Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70). CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

OBJECTIVES: The core pathology of osteoporosis lies in bone resorption exceeding bone formation; thus, promoting osteogenesis is a key therapeutic strategy. The osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) forms the biological basis of bone formation. Astragaloside IV (A-IV), a major active component of Astragalus membranaceus, is known to enhance osteogenesis, but its precise molecular mechanisms remain unclear. This study aims to investigate the effects of A-IV on the proliferation and osteogenic differentiation of BMSCs from osteoporotic rats and to elucidate its molecular mechanism through the regulation of microRNA-21 (miR-21) and Notch2 expression. METHODS: After 1 week of adaptive feeding, mature female SD rats were randomly divided into a sham-operated (Sham) group (n=4) and an ovariectomized (OVX) group (n=8) to establish an osteoporosis model. Twelve weeks after surgery, BMSCs were isolated from femoral bone marrow and cultured. Cells were divided into a S-BMSCs group (from Sham), an O-BMSCs group (from OVX), and an A-BMSCs group (from OVX-derived BMSCs treated with A-IV). S-BMSCs and O-BMSCs were induced for osteogenic differentiation using osteogenic induction medium, whereas A-BMSCs were treated with A-IV before induction. Flow cytometry was used to identify mesenchymal stem cell surface markers (CD29) and hematopoietic stem cell marker (CD34) to confirm BMSC characteristics. Cell proliferation was assessed using the methyl thiazolyl tetrazolium (MTT) assay. Alizarin red staining was performed to quantify calcium nodule formation, and alkaline phosphatase (ALP) activity assays were used to evaluate osteogenic differentiation. Real-time reverse transcription PCR (real-time RT-PCR) was used to detect changes in osteogenic-related genes, runt-related transcription factor 2 (Runx2) and osteopontin (OPN), as well as miR-21 expression. Western blotting was performed to assess Runx2, OPN, and Notch2 protein expression. RESULTS: Flow cytometry confirmed that O-BMSCs retained the phenotypic characteristics of mesenchymal stem cells. A-IV significantly enhanced the proliferation of BMSCs from osteoporotic rats (P<0.05), increased ALP activity, and upregulated the mRNA and protein expression of Runx2 and OPN (P<0.05). Bioinformatic and experimental analyses demonstrated that miR-21 directly targeted Notch2. A-IV treatment increased miR-21 expression while suppressing Notch2 protein expression and inhibiting activation of the Notch signaling pathway (P<0.05). CONCLUSIONS Astragaloside IV promotes the osteogenic differentiation of BMSCs derived from osteoporotic rats by upregulating miR-21 expression and inhibiting the key Notch signaling protein Notch2, thereby relieving the Notch2-mediated suppression of osteogenesis.

Objective To investigate the therapeutic effects of focused ultrasound and ATP-infrared bioeffect for non-neoplastic epithelial disorders of the vulva(NNEDV),aiming to provide references for the clinical study and selection of individualized treatment plans of NNEDV patients.Methods The clinical data of 278 NNEDV patients attending the gynecology department of some hospital from May 2020 to December 2023 were retrospectively analyzed,who were divided into an observation group receiving focused ultrasound treatment and a control group receiving ATP-infrared bioeffect treatment with the single random grouping mmethod.The observation group enrolled in 143 patients including 84 cases of lichen simplex chronicus(LSC)and 59 cases of vulvar lichen sclerosus(VLS),and the control group had 135 patients including 71 LSC cases and 64 VLS cases.Comparisons were carried out in terms of the therapeutic effect and safety in the two groups,the efficacy for LSC and VLS between and within the two groups,and the clinical symptom scores and the quality of life scores before and after treatment of the two groups.SPSS 23.0 software was used for statistical analysis.Results The two groups had no significant differences in response rate and recurrence rate(P>0.05),while the observation group had the cure rate higher and the complication rate higher than those of the control group(P<0.05).In the observation group,the overall response rates for LSC and VLS were not significantly different(P>0.05);in the control group,the overall response rate for LSC was higher than that for VLS significantly(P<0.05).The cure rate for LSC in the observation group was higher than that in the control group,with the differences being statistically significant(P<0.05);the two groups had no significant differences in the cure rate for VLS(P>0.05).The two groups had significant differences in the skin color socre,vitiligo area scoring index and skin elasticity one month,three months and six months after treatment(P<0.05),with the differences being statistically significant in the tissue structure score three months and six months after treatment(P<0.05);there were no significant differences found between the two groups in the pruritus score one month,three months and six months after treatment and in tissue structure score one month after treatment(P>0.05).In the two groups the differences were all statistically significant in the quality of life score three and six months after treatment(P<0.05);the two groups had significant differences in the quality of life score before and after treatment(P>0.05).Conclusion Focused ultrasound and ATP-infrared bioeffect are both effective for NNEDV.Focused ultrasound gains advantages in restoring the color and tissue structure of vulvar skin,and the physical therapy is the first choice for NNEDV that has failed drug therapy and risks for recurrence and canceration;ATP-infrared bioeffect with a low complication rate can be used for the patients with mild symptoms,cracked skin inflammation or those unable to tolerate ultrasound.[Chinese Medical Equipment Journal,2025,46(6):59-64]

Objective:To analyze the efficacy of delineating the clinical target volume (CTV) following the trajectory of trigeminal nerve branches and elective neck irradiation (ENI) in postoperative intensity-modulated radiotherapy (IMRT) for adenoid cystic carcinoma of head and neck (ACCHN).Methods:In this study, the data of ACCHN patients without distal metastasis who received postoperative radiotherapy after radical surgery at the Ninth People's Hospital of Shanghai Jiaotong University School of Medicine from January 2016 to December 2022 were retrospectively analyzed. Postoperative radiotherapy target zone and intensity-modulated radiotherapy plan for ACCHN were formulated according to the site of primary focus, whether nerve invasion and pathological staging. Kaplan-Meier method was applied to perform survival analysis, while assessing the tumor local control rate and locoregional recurrence pattern under this target zone outlining principle.Results:A total of 309 ACCHN patients were included. With a median follow-up of 49 months, the 5-year local control rate was 93.2%, the 5-year overall survival rate, locoregional recurrence-free survival rate, and distant metastasis-free survival rate were 90.8%, 90.6%, 66.3%, respectively. Twenty-three patients developed locoregional recurrence, including 14 with primary tumor recurrence alone, 5 with regional lymph node recurrence alone, and 4 with both primary and regional lymph node recurrence. Among the patients with primary tumor recurrence, 11 had recurrence related to the trigeminal nerve branches,and 7 had recurrence in the tumor bed or surgical bed region, with no out-of-field recurrence. Among the 9 patients with lymph node recurrence, none had undergone neck dissection.Conclusions:Delineating the CTV following the trigeminal nerve branches in postoperative radiotherapy for ACCHN achieves excellent local control. Elective neck irradiation avoids irradiation of the entire neck lymphatic drainage area with a low regional recurrence rate.

Objective:To evaluate the impact of surgical margin status and pathological subtypes on the prognosis of patients with adenoid cystic carcinoma of the head and neck (ACCHN) who underwent postoperative radiotherapy.Methods:A retrospective analysis was conducted on 309 patients with initially treated, non-metastatic ACCHN who completed postoperative radiotherapy at Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. All patients underwent curative (non-palliative) surgery followed by postoperative radiotherapy, with a median dose of 66 Gy (range: 54-70 Gy). The Kaplan-Meier method was used to compare 5-year local recurrence-free survival (LRFS) between R0 (negative margin) and non-R0 resections in patients with initially resectable (T 1-T 4a stage) and initially unresectable (T 4b stage) disease. Univariate and multivariate Cox proportional hazards models were employed to analyze risk factors for local recurrence, with a focus on surgical margin status and pathological subtypes. Results:The median follow-up was 48 months. Of the 309 patients included in the study, 133 were males and 176 were females, with a median age of 51 years (range: 18-77 years). Primary tumors were located in the major salivary glands in 135 cases (including 42 in the parotid gland, 65 in the submandibular gland, and 28 in the sublingual gland) and in the minor salivary glands in 174 cases. The 5-year overall survival, locoregional recurrence-free survival, distant metastasis-free survival, and progression-free survival rates were 91.5%, 90.8%, 66.1%, and 63.9%, respectively. Non-R0 resection was achieved in 177 patients (57.3%). Among initially resectable patients ( n=253), the non-R0 resection rate was 49.0% ( n=124), with only 6 cases (2.4%) experiencing local recurrence (all non-R0 resections). In initially unresectable patients ( n=56), the non-R0 resection rate was as high as 95% ( n=53), with 13 cases (23%) experiencing local recurrence (2 cases in non-R0 resection and 1 case in R0 resection). For initially resectable patients, non-R0 resection significantly reduced the 5-year LRFS rate to 95.2%, compared to 100% in R0 resection patients ( P=0.014). However, multivariate analysis revealed that the solid pathological subtype was an independent risk factor for 5-year LRFS ( HR=7.40, 95% CI: 2.81-19.52, P<0.001), while the surgical margin status was not an independent factor. Conclusions:The combined strategy of surgery and postoperative radiotherapy provides high local control rates for ACCHN patients. Achieving R0 resection is crucial for initially resectable patients, while a comprehensive treatment strategy involving surgery and postoperative radiotherapy remains essential for initially unresectable patients. The solid pathological subtype is the most significant risk factor for local recurrence.

Aim To explore the compatibility and po-tential mechanism of effective components of Biejia-Ezhu against triple negative breast cancer(TNBC)and verify it by experiments.Methods Effective compo-nents and targets of Biejia-Ezhu were obtained by TC-MSP and Swiss Target Prediction.Disease targets of TNBC were obtained from OMMI and GeneCards data-bases.The PPI network was constructed using STRING database.GO and KEGG path enrichment analysis was performed using DAVID database.Cytoscape3.9.1 software was used to construct the"drug-component-target-disease"network,screen key targets and compo-nents for molecular docking,and further verify the com-patibility of key components and targets in vitro.Re-sults ① A total of 71 effective components were iden-tified in the Biejia-Ezhu drug pair.There were 146 drug targets associated with the disease.A total of 113 signaling pathways were identified by KEGG analysis.The 71 potential active components of Biejia-Ezhu mainly acted on key targets such as mTORC1,ULK1,TNF,EGFR,ESR1,STAT3,HIF1A,and PTGS2.Mo-lecular docking results showed that glycine and curcu-min were the key active components of Biejia-Ezhu,and both had strong docking activity against key target proteins mTORC1 and ULK1.②The results of in vitro experiment showed that glycine combined with curcu-min significantly inhibited the proliferation and clonal formation ability of TNBC cells(P＜0.05),up-regula-ted the expression of autophagy marker LC3 Ⅱ/Ⅰ,down-regulated the expression of EGFR,down-regula-ted the expression of pathway protein mTORC1,p-mTOR,p-ULK1,and promoted the expression of path-way protein ULK1(P＜0.05).Conclusion The key component of Biejia-Ezhu against triple-negative breast cancer is glycine-curcumin,the mechanism of which may be related to the regulation of the mTORC1/ULK1 signaling pathway to promote autophagy.
