Bioactive compounds derived from herbal medicinal plants modulate various therapeutic targets and signaling pathways associated with cardiovascular diseases (CVDs), the world's primary cause of death. Ginkgo biloba, a well-known traditional Chinese medicine with notable cardiovascular actions, has been used as a cardio- and cerebrovascular therapeutic drug and nutraceutical in Asian countries for centuries. Preclinical studies have shown that ginkgolide B, a bioactive component in Ginkgo biloba, can ameliorate atherosclerosis in cultured vascular cells and disease models. Of clinical relevance, several clinical trials are ongoing or being completed to examine the efficacy and safety of ginkgolide B-related drug preparations in the prevention of cerebrovascular diseases, such as ischemia stroke. Here, we present a comprehensive review of the pharmacological activities, pharmacokinetic characteristics, and mechanisms of action of ginkgolide B in atherosclerosis prevention and therapy. We highlight new molecular targets of ginkgolide B, including nicotinamide adenine dinucleotide phosphate oxidases (NADPH oxidase), lectin-like oxidized LDL receptor-1 (LOX-1), sirtuin 1 (SIRT1), platelet-activating factor (PAF), proprotein convertase subtilisin/kexin type 9 (PCSK9) and others. Finally, we provide an overview and discussion of the therapeutic potential of ginkgolide B and highlight the future perspective of developing ginkgolide B as an effective therapeutic agent for treating atherosclerosis.

Objective To summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). Methods The clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. Results A total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. Conclusion AAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.

Purpose To explore the value of insulinoma associated protein 1(INSM1)in the pathological diagnosis and differential diagnosis of medullary thyroid carcinoma(MTC).Methods Twenty-eight cases of MTC were collected as the ex-perimental group and 25 cases of thyroid tumors(6 cases of transparent trabecular tumors,16 cases of poorly differentiated cancer,2 cases of spindle cell papillary carcinoma,and 1 case of thyroid paraganglioma)that needed to be differentiated from MTC in the same period were collected as the control group.The expression of INSM1 was detected using immunohistochemical EnVision method,and the sensitivity and specificity of INSM1 in MTC were analyzed,and compared with traditional MTC markers(Syn,CgA,CT,and CEA).Results The positive rate of IN-SM1 in the MTC group was96.4%(27/28),significantly high-er than the control group of 4.0%(1/25)(P<0.05).INSM1 had a sensitivity of 96.4%in MTC,significantly higher than CgA(71.4%)(P<0.05),and was positively expressed in CT negative MTC cases.The specificity of INSM1 in MTC was 96.0%,significantly higher than that of CEA(72.0%)(P<0.05).Conclusion INSM1 has high sensitivity and specificity in MTC,with a nuclear positive staining pattern,clear back-ground,and easy identification.It is superior to the traditional biomarkers and has high diagnostic value in MTC.

Objective To observe the effect of neuromuscular electrical stimulation on bone angiogene-sis and osteoporosis induced by denervation in sarcopenia osteoporosis rats,and explore the correlation of the miRNA expression level in circulating extracellular vesicles to bone angiogenesis and osteoporo-sis.Methods Ten-week-old male Sprague-Dawley rats were randomly divided into a sham operation control group(con,n=8),a double leg tibial nerve loss group(DD,n=8)and a double leg tibial nerve loss + right leg electrical stimulation group(D+ES,n=8).The tibial nerve of both legs was re-moved in DD and D+ES groups,and one week later the D+ES group received 8-week neuromuscular electrical stimulation.Samples were taken 24 hours after the last stimulation.Trabecular bone parame-ters were detected using micro-CT and its morphology was observed using hematoxylin and eosin(HE)staining.Immunohistochemical staining was used to identify the vascular markers platelet endothe-lial cell adhesion molecule-1(PECAM-1/CD31)and vascular endothelial growth factor A(VEGFA).Moreover,plasma exosomes were extracted and purified,and the vesicles were identified by electron microscopy,nanoparticle tracking analysis(NTA)and Western blotting.Meanwhile,the real time PCR was used to determine the expression of myogenic miR-1,miR-133a,miR-133b and miR-206 in exo-somes.Results(1)Compared with the CON group,the volume and weight of gastrocnemius and sole-us muscles in the DD group reduced significantly(P＜0.001),and the tibial trabecular bone parameters changed pathologically.After 8-week stimulation,compared with the DD group,the volume and weight of gastrocnemius and soleus muscles in D+ES group increased significantly(P＜0.05),and tibial trabecular bone parameters improved significantly.(2)The immunohistochemical staining results indicat-ed that,compared with CON group,the expression of CD31 and VEGFA in the tibia of DD group re-duced significantly,while that of the D+ES group increased significantly compared with DD group.(3)The results of NTA showed that,compared with CON group,the concentration of circulating extra-cellular vesicles in the DD group decreased significantly(P＜0.001),and the expression of miR-1,miR-133a,miR-133b and miR-206 in exosomes increased significantly(P＜0.05,P＜0.01,P＜0.05,P＜0.05 respectively).Compared with the DD group,the concentration of circulating exosomes in D+ES group increased significantly(P＜0.05),and the expression of the above four miRNAs decreased signifi-cantly(P＜0.05 for all).Conclusion Tibial nerve denervation can successfully establish the model of sar-copenia osteoporosis and neuromuscular electrical stimulation significantly relieves such denervation in-duced changes.Moreover,electrical stimulation also significantly increases the concentration of circulat-ing exosomes,and the expression of myogenic miRNAs carried by them,which suggests that the latter may be related to bone angiogenesis and the progression of osteoporosis.

Objective:Based on the business reengineering theory, to construct the emergency nursing process of acute massive hemoptysis in hospital and explore the effect of it.Methods:According to the order of hospitalization, 200 patients with acute massive hemoptysis admitted to the emergency department in Shanghai Pulmonary Hospital Affilated to Tongji University from January to June in 2020 were selected as the control group, and the original treatment process was adopted. Two hundred patients admitted to the emergency department of this hospital from July to December in 2020 were selected as the experimental group, and the reconstructed in-hospital emergency nursing process for acute massive hemoptysis was applied. In both groups, the researchers recorded the time spent in each sub-process by using the in-hospital treatment time record of acute massive hemoptysis and collected the clinical outcomes of patients through electronic cases. The time-consuming, treatment efficiency and patient outcome of each link of the treatment process in the backyard of the two groups were compared.Results:Finally, 192 patients were enrolled in the control group and the experimental group. The median time from admission to intravenous use of hemostatic drugs and from admission to endovascular treatment in the experimental group were 21.50(20.00, 22.50) and 82.50(79.50, 84.50) min, which were lower than those in the control group which spent 40.87(37.06, 44.43) and 135.50(123.50, 147.00) min, and the differences between the two groups were statistically significant ( Z=-16.84, 16.63, both P<0.01). The incidence of asphyxia caused by acute massive hemoptysis in the experimental group was 4.2%(8/192), which was lower than that in the control group, which was 13.0%(25/192) . There was a statistically significant difference in the incidence of asphyxia between the two groups( χ2=9.58, P<0.01). Conclusions:The emergency nursing process of acute massive hemoptysis effectively shortens the time of in-hospital treatment of acute massive hemoptysis, further promotes the seamless connection of multiple links of in-hospital treatment of acute massive hemoptysis, and improves the overall efficiency of in-hospital treatment of patients with acute massive hemoptysis.
