ObjectiveChinese patent medicines for cardiovascular and cerebrovascular diseases are diverse and complex in their efficacy. The traditional classification method based on efficacy categories has certain limitations and cannot meet the clinical needs for individualized drug selection and variety comparison. This article， based on the formulation compatibility analysis technology of "Tangye Jingfa Tu"， clarifies the composition and efficacy characteristics of common Chinese patent medicines used for cardiovascular and cerebrovascular diseases， providing support for the precise selection of these medicines. MethodsFifty-six representative Chinese patent medicines， covering all the efficacy subcategories of "stasis-resolving agents" in the National Basic Medical Insurance， Work Injury Insurance， and Maternity Insurance Drug Catalogue （2023） （more than 50% of the total）， were selected for the study. Within the knowledge system of "Tangye Jingfa Tu"， the compatibility structure of herbal flavors and the proportion structure of herbal quantities for each Chinese patent medicine were determined. The correlation between these structures and the efficacy categories was analyzed to identify the similarities and differences among the selected Chinese patent medicines. Additionally， the efficacy was reclassified and compared according to the theoretical framework of tonifying and purging methods of five Zang organs in the "Tangye Jingfa Tu". ResultsThe representative Chinese patent medicines included in the analysis were Shexiang Baoxin pills， Danshen tablets， Qili Qiangxin capsules， Breviscapine tablets， etc.， covering all the efficacy subcategories of "stasis-resolving agents". Among the 56 representative Chinese patent medicines， salty flavor was the most common （48）， followed by pungent （33）， and sweet （26）. According to the dominant herbal flavor， salty flavor was the most common （37）， followed by pungent （9）， and sour （5）. According to the dominant herbal quantity， salty flavor was the most common （27）， followed by sour （7）， and pungent （5）. Furthermore， Chinese patent medicines with different efficacy subtypes showed different flavor characteristics. For example， most Qi-invigorating and blood-activating agents contained sweet drugs for tonifying the spleen （9/10）， most Qi-moving and blood-activating agents contained pungent drugs for tonifying the liver （7/8）， and all kidney-invigorating and blood-activating agents contained bitter drugs for tonifying the kidneys （6/6）. However， the efficacy classification of individual medicines did not always align with the compatibility characteristics of their formulas， as seen with Dengyin Naotong capsules. ConclusionThe formulations of Chinese patent medicines for cardiovascular and cerebrovascular diseases predominantly feature salty， sour， and pungent flavors， which largely conform to the therapeutic principles of "nourishing the heart with salt and soothing the heart with sour" and the liver-heart， heart-spleen mother-child treatment relationship shown in the "Tangye Jingfa Tu". Using the "Tangye Jingfa Tu" framework to conduct research on the structure and efficacy characteristics of Chinese patent medicines is objective and effective.

To improve the current situation of multiple preoperative visits and evaluations for elderly patients and other patients with complex conditions, in December 2022, Peking Union Medical College Hospital established preoperative multidisciplinary evaluation clinic (shorted as joint clinic). The joint clinic established a multidisciplinary team, clarified service targets, and developed standardized clinic workflows to provide patients with a " one-stop" preoperative assessment(physical fitness assessment, nutritional assessment, and frailty assessment, etc.), nutritional optimization intervention, and prerehabilitation education and guidance services. This practice strengthened preoperative risk management, improved preoperative assessment efficiency, and ensured the safety of patients during the perioperative period. As of September 2023, the joint clinic had received a total of 128 patients, of which 86 underwent surgery after preoperative evaluation and prehabilitation optimization. The obesity rate, smoking rate, and number of frailty cases of these patients had decreased from 13.96%, 11.63%, and 18 at the time of visit to 9.30%, 4.65%, and 14 on the day before surgery, respectively. They had recovered well after surgery. This practice had improved the preoperative status of patients and created conditions for high-risk patients to undergo surgery smoothly, so as to provide references for other hospitals to carry out multidisciplinary collaborative preoperative evaluation works.

Objective To investigate clinicians'practice and opinions on sedation therapy in end-stage patients at Peking Union Medical College Hospital.Methods From August,2022 to April,2023,an online questionnaire survey was conducted among clinicians involved in end-stage patient management.Results A total of 205 questionnaires were distributed,with an effective response rate of 56.1% .Among the clinicians,55.7% of them had experience of applying sedation therapy in end-stage patients;85.2% of clinicians believed that se-dation could relieve the suffering of terminal patients from physical refractory symptoms;75.7% of clinicians considered that sedation therapy could be used to relieve agony from psycho-existential distress.Most clinicians had concerns about sedation therapy due to the lack of legal support(86.1% )and the lack of understanding of patients or families(59.1% ).The majority(90.4% )of clinicians were willing to receive training on palliative sedation.Conclusions A majority of clinicians agree that sedation therapy could relieve the physical distress and psycho-existential distress in end-stage patients.However,most clinicians have concerns about the application of sedation therapy due to the lack of legal support.It is necessary to enhance the training on palliative sedation.

Objective:To investigate the characteristics, diagnosis and therapeutic effect of acquired lymphangiectasia of the vulva (ALV).Methods:A retrospective analysis of clinicopathological and follow-up data was conducted on the patients treated in Capital Medical University Affiliated Beijing Shijitan Hospital due to female ALV from July 2009 to July 2023. The patients who completed the staged operations [partial labiectomy and reconstruction + thoracic ductplasty and (or) perineal lymphovenous anastomosis] were included in the study and followed up. The improvement of perineal swelling, blister range, fluid leakage volume and frequency were evaluated through outpatient visits by the symptom rating scale of ALV (hereinafter referred to as the symptom rating scale) before and after surgery.Results:A total of 48 patients were treated due to ALV from July 2009 to July 2023, of which 98% (47/48) were postoperative pelvic malignant tumors and 94% (45/48) had a history of radiotherapy. A total of 10 patients with ALV who completed the staged operations were included in this study. (1) Clinical characteristics and diagnosis: 10 patients had a median age of 60 years old (50, 63 years old ). The median duration from cervical cancer surgery and radiation therapy to vulvar swelling was 1.5 years (0.0, 2.0 years), and the median duration from vulvar swelling to blister formation and leakage was 0.0 years (0.0, 4.8 years). Seven patients (7/10) had a history of recurrent erysipelas; 7 patients (7/10) had the most severe symptom (widespread blisters, persistent fluid leakage, and large amount of fluid leakage); noncontrast magnetic resonance lymphography (NCMRL) showed edema signals in the perineal region of all the patients, and increase of agent in the perineal region was observed in lymphoscintigram (LS). (2) Surgical treatment and postoperative pathological examination: of the 10 ALV patients who completed staged surgical treatment, 6 cases (6/10) were diagnosed with thoracic duct outlet obstruction and underwent thoracic ductplasty and partial labiectomy and reconstruction. Perineal lymphovenous anastomosis and partial labiectomy and reconstruction were performed in 4 cases (4/10) without thoracic duct outlet obstruction. Postoperative routine pathological examination of 10 patients (10/10) showed dermal papilla lymphangiectasia. Immunohistochemical tests were performed on 5 patients, all of which were positive for D2-40 and negative for CD 34. (3) Efficacy: 8 patients completed the postoperative follow-up, and the median follow-up time was 31.0 months (17.5, 78.3 months). The perineal swelling and the blister fluid leakage were all significantly improved after the staged operations. All indexes of the symptom rating scale, including the degree of perineal swelling, blister range, fluid leakage volume and frequency, were significantly improved in 8 follow-up patients, and 3 (3/8) of them were cured; the median symptom score decreased significantly from 11.0 before surgery to 3.0 after surgery ( P<0.001). The incidence of erysipelas was significantly reduced from 7/10 before surgery to 2/8 after surgery ( P=0.035). Conclusions:The main causes of female ALV are pelvic tumor surgery and radiotherapy. The clinical diagnosis is made from relevant medical history, clinical manifestations, LS and magnetic resonance imaging. The diagnosis is confirmed by histopathological findings. Pathological results show lymphangiectasia in the dermal papilla, and immunohistochemical staining show positive for D2-40 and negative for CD 34. The effect of staged surgery on ALV is remarkable and even cured, and could effectively reduce the incidence of erysipelas.

Objective:To explore the relationship between the degree of devascularization and clinical outcomes after interventional embolization and sclerotherapy for peripheral arteriovenous malformations.Method:A retrospective analysis was conducted on the data of 37 patients with peripheral arteriovenous malformations admitted at Department of Cardiovascular Surgery, China-Japan Friendship Hospital from July 2021 to June 2023. All patients received the treatment of "nidus" and/or outflow veins embolization combined with sclerotherapy injection. Two experienced physicians evaluated the degree of devascularization before and after treatment, and conducted a correlation study with clinical outcomes after follow-up.Result:All 37 patients were symptomatic. Swelling and pain accounted for 75.7% of all the cases. Twenty-six patients received only one procedure, 3 patients received re-interventional treatments. The average follow-up time was（13.3±5.0）months. Clinical symptoms were completely relieved in 14 patients, and partial relief in 22 patients. The overall effective rate was 97%. There were 6 patients with degree of de vascularization<50% during procedure, 16 patients with degree of 50%-75%, and 5 patients with degree of 75%-90%, 10 cases with degree over 90%. Patients with devascularization degrees less than 60% can not achieve clinical symptom relief.Conclusions:There is a positive correlation between the degree of devascularization and clinical outcomes in the interventional embolization and sclerotherapy of peripheral arteriovenous malformations, and 60% of the degree of devascularization can serve as the "threshold" for effectiveness of treatment.

Objective To examine the differential expression of plasma circRNA in individuals with type 2 diabetes mellitus(T2DM)and to elucidate the potential role of circRNA in the pathogenesis and progression of T2DM.Methods A total of 33 newly diagnosed T2DM patients who were hospitalized in the Department of Endocrinology of Heze Municipal Hospital and 33 healthy subjects with normal glucose tolerance(NC)were enrolled in this study from March 2022 to March 2023.Three subjects with T2DM and 3 with NC were randomly selected from study population and underwent high-throughput sequencing to identify differentially expressed circRNA.Six circRNA with significant differences were selected,and validated in the remaining study population using Real-Time Quantitative Polymerase Chain Reaction(RT-qPCR).Bioinformatics analyses were conducted on the differentially expressed circRNA-associated genes,and their interaction with microRNA(miRNA)was predicted.Results Microarray analysis revealed 166 significantly differentially expressed circRNA(FC≥2,P<0.05)in the T2DM group compared with NC group.Among them,137 were up-regulated and 29 were down-regulated.RT-qPCR validation of six circRNA showed that the expression level of hsa_circ_0000705 was significantly higher,while the expression levels of hsa_circ_0005362 and hsa_circ_0042839 were significantly lower in T2DM group,consistent with the microarray results.However,hsa_circ_0117392,hsa_circ_0008311,and hsa_circ_0087641 showed no significant changes.Conclusion Differentially expressed circRNA are present in T2DM patients.Hsa_circ_0005362 was significantly down-regulated and may be involved in the development of T2DM through the regulation of related signaling pathways by targeting miR-128-1-5p.

Objective To explore the mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Methods The expression of miR-153 in cerebral hemorrhage was analyzed by miRNA microarray and RT-PCR,and the relationship between miR-153 and neuronal apoptosis in cerebral hemorrhage was observed,and predicted the target gene of miR-153;the binding of miR-153 to target genes was studied by dual-luciferase reporter gene Experiments,and to observe the effects of overexpression and inhibition of miR-153 on target genes.Subsequently,the relationship between target genes and neuronal apoptosis in cerebral hemorrhage was determined.Finally,the effect of Jianshen Lishui Decoction on miR-153 and the target gene,and finally explored the related mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Results Microarray chip and RT-PCR detection showed that miR-153 was lowly expressed in cerebral hemorrhage(P<0.05),and miR-153 was negatively correlated with neuronal apoptosis(R:-0.875,P=0.0002).The online databases TargetScan and miRDB showed that miR-153 has a binding region with TREM1,and the dual-luciferase reporter gene demonstrated a binding relationship between the two.When miR-153 was overexpressed,the expression of TREM1 was down-regulated,conversely,up-regulated when miR-153 was repressed,and TREM1 was positively correlated with nerve cell apoptosis(R:0.857,P<0.001).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction group were lower than those in the model group(P<0.05),and the expression of miR-153 was higher than that in the model group(P<0.05).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction +miR-153 inhibition group were higher than those in the Jianshen Lishui Decoction group(P<0.05).Conclusion Jianshen Lishui Decoction inhibits the apoptosis of nerve cells and protects the neurologicalfunctions in rats with cerebral hemorrhage by promoting miR-153 expression and inhibitingTREM1 expression.

Objective:To explore the significance of multiple frequency bioelectrical impedance analysis (MFBIA) in the combined surgical treatment of breast cancer-related lymphedema (BCRL).Methods:A retrospective analysis was conducted on the clinical data of 30 patients with unilateral postoperative BCRL. The patients recieved staged liposuction and lymphaticovenular anastomosis (LVA) from April to October 2021 at the Department of Lymphatic Surgery in Beijing Shijitan Hospital, Capital Medical University. After LVA surgery, patients were followed-up by telephone and other means, and asked to come to the hospital at 1 year and 2 years, respectively. The circumference of each part of the upper limbs, the length of forearm and arm were measured, and the limb volume was calculated. MFBIA were also performed to record limb bioelectrical impedance, extracellular water(ECW), and extracellular water ratios (ECW/TBW). SPSS 21.0 was used for statistical analysis. Clinical data of the patients were analysed by One-way Repeated Measurement Anova to examine the changes in volume of the affected arms before and after surgery and the changes in values collected by MFBIA. Subsequently, differences in the volumes and values of MFBIA of the affected arms before and after surgery, and the ratios of the above were analysed by paired t-test to compare each pair, then followed by Pearson correlation test. P<0.05 was considered statistically significant. Results:After liposuction, the volume differences of affected and healthy arms were reduced from 1 147 ml ± 484 ml before surgery to 261 ml ± 304 ml after surgery, which achieved a significant reduction with statistical significance ( P<0.05). However, there were no significant changes in ECW or bioelectrical impedance at various frequencies (1-1 000 K) ( P>0.05). After LVA, the differences in volume of the affected and healthy arms further decreased to 17 ml±264 ml with statistical significance compared to that before surgery ( P<0.05), ECW decreased from 1.115 L ± 0.207 L to 0.937 L ± 0.164 L with statistical significance ( P<0.05), ECW/TBW decreased from 0.412 ± 0.008 to 0.405 ± 0.007 with statistical significance ( P<0.05), and the bioelectrical impedance at various frequencies was significantly increased with statistical significance ( P<0.05). After LVA, the difference in arm volume was positively correlated with the difference in ECW (correlation coefficient 0.602, P<0.05), positively correlated with the difference in Rate of ECW (correlation coefficient 0.560, P<0.05), and negatively correlated with the ratios of impedance at various frequencies (correlation coefficients 0.529-0.545, P<0.05). Conclusion:In the staged surgical treatment of BCRL, with the application of MFBIA, it is found that lymphatic liposuction removes the pathological adipose tissue of an arm, hence significantly reduces the volume of the affected arm. However, lymphatic stasis remains unrelieved, therefore without a significant reduction in arm oedema. After the second-stage LVA, the improvement of lymphatic return leads to the relief of arm oedema, and the volume of the affected arm approaches to that of the healthy side. MFBIA can be used for assessment of arm oedema.

Objective:To investigate the characteristics and diagnostic methods for the patients with primary lymphedema and interstitial lung disease, as well as the efficacy of thoracic duct or right lymphatic duct plasty.Methods:A retrospective study was performed on 13 patients who were treated for primary lymphedema in the Department of Lymphatic Surgery, Beijing Shijitan Hospital, Capital Medical University, from January 2018 to December 2022. All patients were confirmed with interstitial lung disease by high-resolution CT (HRCT) and then underwent thoracic duct or right lymphatic duct plasty surgery. The 13 patients in this study were 7 males and 6 females aged 7.3 (0.7-30.0) years old. Primary lymphedema was the first manifestation in all patients, with an average morbidity age at 1.0 (0-11.0) years old. The average time from the onset of lymphedema to the confirmed interstitial lung disease was 6.3 (0.3-19.0) years. All patients underwent thoracic duct or right lymphatic duct plasty for improvement of the lymphatic flow. In addition, 9 cases (69.2%) received a direct lymphangiography (DLG). In which, 4 cases (44.4%) received further treatment of ligation of the reflux branches, and 1 (11.1%) had the treatment plans changed, because a chylous reflux into the lung through a bronchomediastinal trunk was found from DLG, therefore a ligation of the abnormal reflux branches was performed and a life-long strict low-fat diet was required. Postoperative follow-ups for evaluation of the improvements of lymphedema and pulmonary lymphatic flow were carried out by visit of outpatient clinic or via telephone interviews.Results:All patients recovered well after surgery with an average follow-up time of 47.5 (19.0-68.0) months. Lymphedema was stable in 2 cases (15.4%) and relieved in 11 cases (84.6%). Ten cases (76.9%) had completed the postoperative HRCT reviews and 9 (90.0%) were found with significant improvement in the interstitial lung disease.Conclusion:The interstitial lung disease found during the examination of patients with primary lymphedema can be explained with a lymphatic flow disorder. DLG can identify the cause and make to guide the treatment. Thoracic duct or right lymphatic duct plasty can effectively improve both of the symptom of lymphedema and interstitial lung disease.
