BACKGROUND:Large randomized controled clinical trials have shown that drug-eluting stents has a lower
restenosis rate compared with bare-metal stents, but the drug-eluting stents cannot reduce major cardiovascular events and death rates, and long-term folow-up of clinical registries show the drug-eluting stents even may
increase late stent thrombosis events.
OBJECTIVE:To evaluate the incidence of stenosis and adverse reactions after treatment with biodegradable, non-biodegradable drug-eluting stents and bare-metal stents in patients after myocardial infarction.
METHODS:We retrospectively analyzed the clinical data of 236 cases of acute myocardial infarction, in which 79 cases were treated with biodegradable sirolimus-eluting stents, 83 cases treated with non-biodegradable
sirolimus-eluting stents, and 74 cases treated with bare metal stents. Then, we compared late lumen loss and restenosis within 12 months after stent implantation and major adverse cardiac reactions within 24 months after stent implantation.
RESULTS AND CONCLUSION: After 12 months, the late lumen loss of the bare stent group was significantly higher than that of biodegradable and non-biodegradable sirolimus-eluting stent groups (P < 0.05), but the
difference in stent restenosis rate (P > 0.05). After 24 months, there were no differences in death, cardiac death, recurrent myocardial infarction, target vessel revascularization, target lesion revascularization, major adverse
cardiac events and stent thrombosis events among the three groups. These three kinds of stents need to be
further studied in their long-term efficacy and safety as percutaneous coronary intervention for acute ST-segment elevation myocardial infarction.

Abstract: Objective　To investigate the cause of poisoning leading to multi-organ damage in a patient with an unexplained condition, to confirm the type and exposure amount of the pathogenic factor, to identify the sources of pathogenic factors, and to provide references and bases for the clinical treatment and the prevention of such events. Methods　Starting with the unknown traditional Chinese medicine taken by patients for a long time, the targeted screening strategy was initially used to screen for alkaloid poisoning. Subsequently, a non-targeted screening strategy using Information-dependent Acquisition Mode (IDA) was used to screen the patient's blood, urine, and drug samples. Combining the toxicological effects of suspected compounds with the patient′s clinical manifestations, the main pathogenic factors were determined. Quantitative methods were established according to standard substances to quantify the pathogenic factors in all the samples. An epidemiological investigation was conducted to obtain the patient's medication history, and combined with the examination of the medication's specifications and content, the exposure dose of each pathogenic factor was determined. Finally, a Data data-independent acquisition (DIA) mode termed Sequential Window Acquisition of All Theoretical Fragment-Ion Spectra (SWATH) was used to screen all samples, unbiasedly collecting secondary mass spectrometry information of compounds, thereby verifying and supplementing the confirmed pathogenic factors. Results　Targeted screening ruled out common alkaloid poisoning. Tadalafil was detected in the patient's blood and urine. Tadalafil, sildenafil, chloropretadalafil, acetaminophen, and diclofenac were detected in unknown traditional Chinese medicine. The side effects of these compounds were consistent with the clinical manifestations of the patient. The highest daily average exposure doses of tadalafil, sildenafil, chloropretadalafil, acetaminophen, and diclofenac were 30.5 mg, 15.8 mg, 0.05 mg, 45.6 mg, and 3.2 mg respectively, which were seriously excessive. The SWATH mode also screened out the above five drugs. In addition, palmatine chloride was also detected. Conclusions　Combining the patient's clinical manifestations and epidemiological data, this study integrated targeted screening, untargeted screening, targeted quantitative strategies, data-dependent, and DIA mode to confirm that this case is a drug poisoning event caused by long-term overdose consumption of traditional Chinese medicine adulterated with chemical components. This study provides insights for the diagnosis and investigation of patients with poisoning for unknown causes, offering references for emergency detection and management of related poisoning incidents.

Objective To study the functional mechanism of Yougui Pill(Right Restoring Pill)through its effect on cerebral gene of mice models with kidney-yang asthenia caused by excessive physical and sexual activity.Methods There were 10,15,10 male mice in the control,model and treatment groups respectively.The control and model groups were treated with 0.5ml permouse perday distilled water by gavage while the treatment group was given 0.5ml permouse perday suspension of Yougui Pill.In the model and treatment groups,the ratio of male and female was 1∶6,feeding in the same cage,and the males were swimming everyday for 30~40 minutes,4 weeks in succession,to induce the kidney-yang asthenia.The 36K mouse cerebral gene chips were used to measure the brain genes of mice of 3 groups.The intensity ratio of fluorescence signals ≥2 and ≤0.5 were used as the scale to screen out the remarkably different genes.Results In the model and control groups,totally 186 gene with different expressions were screened out,including the 150 up-regulated genes and 36 down-regulated genes.In the treatment and model groups,155 gene with different expressions were screened out,including the up-regulated 64 genes and 91 down-regulated genes.There were 32 genes up-regulated in the model and control groups but down-regulated in the treatment and model groups,mainly involving the inflammation perimmunity and neurotransmissions persignal transduction genes.There were 12 genes down-regulated in the model and control groups but up-regulated in the treatment and model group,mainly involving the hormone related genes of melanin and orphan nuclear receptor.Conclusion Yougui Pill may make the notably down-regulated genes of melanin markedly up-regulated in mice models of kidney-yang asthenia,improving the effect of hormone related orphan nuclear receptor and promoting the cellular proliferation.

The purpose of the present study was to assess the correlation that likely exists among increased portal pressure (Pp), portal blood flow quantity (Qp) and ETA and ETB receptor mRNA expression in human cirrhosis. In situ hybridization and reverse-transcription polymerase chain reactions (RT-PCR) were performed to determined the expression of ETA and ETB receptor mRNA in liver tissues from traumatic subjects (n = 10) and cirrhotic patients (n = 15) in whom hepatic hemodynamic values were measured. The expression of the two transcripts was significantly higher in liver samples of cirrhotic patients than in those obtained from traumatic subjects. It has shown that ETA receptor mRNA predominantly located in hepatic stellate cells (HSCs) and vascular smooth muscle cells of intrahepatic arteries and portal veins, ETB receptor mRNA in HSCs, sinusoidal endothelial cells and Kuppfer cells. There was a highly significant direct relationship between ETA and ETB receptor mRNA and Pp and Qp in cirrhotic patients. It suggests that liver paracrine endothelin system may be overactivated in human cirrhosis accompanied with increased expression of ETA and ETB receptor mRNA which may play an important role in the pathogenesis and maintenance of splanchnic hyperdynamics.

Bone marrow stem cells(BMSCs) can differentiate into cardiomyocytes when induced with proper reagent. The cardiomyocytes from BMSCs have cardiomyocyte phenotypes with the expression of cardiac-specific antigen and receptor. BMSCs differentiate into cardiomyocytes in host myocardial microenvironments. Mechanism of the differentiation is unclear and need to be studied further.

BACKGROUND:Chronic ankle instability affects normal life severely. Therefore, chronic ankle instability causes more and more attention of experts, and choice of reasonable and effective diagnosis and targeted treatment method for chronic ankle instability in early stage has become an important issue in the clinic.
OBJECTIVE:To review literature research on the diagnosis and treatment of chronic ankle instability in recent years, and to provide reference and evaluation criteria for the diagnosis and reasonable and effective treatment of chronic ankle instability in clinical practice.
METHODS:We searched PubMed database, China National Knowledge Infrastructure, Wanfang database and VIP database for clinical and basic experimental research on chronic ankle instability. Keywords were“chronic ankle, instability, diagnosis, rehabilitation exercises, surgery methods, research progress”in Chinese and“chronic ankle, instability, diagnosis, rehabilitation exercises, surgical methods, research”in English. Total y 40 literatures were analyzed.
RESULTS AND CONCLUSION:Because of the special anatomical features and biomechanical advantages of the ankle, we should first consider the early diagnosis and effective treatment in chronic ankle instability patients. The treatment should focus on the anatomic characteristics, biomechanic characteristics, etiology of chronic ankle and diagnostic methods of the ankle joint. Conservative treatment and rehabilitation exercises after surgery play a major role in the recovery of chronic ankle instability. The use of balance board, tilting board, and climbing machines is an effective rehabilitation exercises for chronic ankle instability. The application of AOFOS-hind foot and ankle fibula reaction time is important for the assessment of functional recovery of the ankle joint. The emergence of arthroscope is an important clinical research direction of ankle surgery. This plays a significant effect on the treatment of chronic ankle instability.
