Objective To explore the accuracy of three dimensional speckle tracking imaging (3D-STI) in quantitative coronary evaluation of (CHD) patients' left ventricular global systolic function.Methods Sixty-eight CHD patients were divided into three groups according to the coronary artery angiography (CAG) results:32 cases in severe stenosis group,23 cases in moderate stenosis group,and 13 cases in mild stenosis group.Thirty gender-age-matched healthy subjects(control group) were enrolled in this study.All patients underwent 2D-echocardiography and real-time three-dimensional echocardiography (3DE).The global longitudinal strain(GLS),global radial strain(GRS),global circumferential strain(GCS),global area strain (GAS),global area strain rate (GASrate) and 3D global LV strain (3D-Strain) were analyzed using 3D-STI.Correlation between strain measurements and left ventricular ejection fraction (LVEF) by simpson method,3D-LVEF by 3DE were assessed using linear regression analysis.Results All 3D-STI parameters in the severe stenosis group were significant decreased compared with the other groups.GLS,GRS,GCS,GAS,3D-Strain of moderate stenosis group shown more significant decrease than both mild stenosis group and control group (P ＜ 0.05).Strong correlations were demonstrated in all 3D-STI parameters between 3D-LVEF and LVEF.The strongest correlation was observed between GAS with 3D-LVEF in severe stenosis group(r =-0.910,P ＜0.05).Intraobserver and interobserver reliability of GAS was better than other parameters.Conclusions Global strain of 3D-STI can quantitatively evaluate the global LV function in CHD patients,and GAS is more sensitive and reproducible than other parameters.

Objective To establish a mouse model of kidney-yin and kidney?yang deficiency after oral administra?tion of hydrocortisone, and to explore the related evaluation factors. Methods The model was established by oral adminis?tration of hydrocortisone to induce kidney?yin and kidney?yang deficiency in mice. The survival and body weight of the mice were observed. The serum content of adrenal cortical hormone ( ACTH) , cortisol ( Cor. ) in the hypothalamic?pituitary?ad?renal (HPA) axis, and thyroid stimulating hormone (TSH), triiodothyronine (T3), thyrox (T4) in the hypothalamic?pi?tuitary?thyroid (HPT) axis, follicle?stimulating hormone (FSH), estradiol (E2), testosterone (T) in the hypothalamic?pituitary?gonadal ( HPG) axis were determined by radioimmunoassay. Results The body weight of kidney?yin and kidney?yang mice were decreased, the serum ACTH, Cor, TSH, T3, T4 contents were decreased, the serum FSH, E2, T contents were increased in the kidney?yang deficiency model mce ( P<0. 01 ) , and those parameters in the kidney?yin deficiency model mice were changed in opposite direction. Conclusions It is found that the hormone levels of ACTH, Cor, TSH, T3, T4, FSH, E2 and T in kidney deficiency mice are changed, and cortisol can be used as an important index to evaluate the model of kidney deficiency induced by glucocorticoid.

Serbia is a parliamentary republic country in Southeast Europe. It implements a health security system with social insurance as the mainstay and social assistance as a supplement. Ischemic heart disease, stroke and Alzheimer’s disease are the major causes of death, and the mortality rates of cardiomyopathy and chronic kidney disease are increasing. Serbia has relevant legislation on traditional medicine. Acupuncture, as the main form of Traditional Chinese Medicine (TCM), has been introduced to Serbia in an early stage. Acupuncture was recognized as a legal medical method in 2005, and then the corresponding educational institutions of TCM were established soon. However, the limitation of acupuncture treatment application, difficulty in access to Chinese medicine, and undeveloped of TCM education system, all of them restrict the development of TCM in Serbia. It is recommended to improve the development and dissemination of Chinese medicine in Serbia, like to increase the promotion of acupuncture, pay attention to the Chinese medicine for preventive health care, and strengthen TCM education.

Purpose: Neoadjuvant therapy modality can increase the operability rate and mitigate pathological risks in locally advanced cervical cancer, but treatment response varies widely. It remains unclear whether genetic alterations correlate with the response to neoadjuvant therapy and disease-free survival (DFS) in locally advanced cervical cancer. Materials and Methods: A total of 62 locally advanced cervical cancer (stage IB-IIA) patients who received neoadjuvant chemoradiation plus radical hysterectomy were retrospectively analyzed. Patients’ tumor biopsy samples were comprehensively profiled using targeted next generation sequencing. Pathologic response to neoadjuvant treatment and DFS were evaluated against the association with genomic traits. Results: Genetic alterations of PIK3CA were most frequent (37%), comparable to that of Caucasian populations from The Cancer Genome Atlas. The mutation frequency of genes including TERT, POLD1, NOS2, and FGFR3 was significantly higher in Chinese patients whereas RPTOR, EGFR, and TP53 were underrepresented in comparison to Caucasians. Germline mutations were identified in 21% (13/62) of the cohort and more than half (57%) had mutations in DNA damage repair genes, including BRCA1/2, TP53 and PALB2. Importantly, high tumor mutation burden, TP53 polymorphism (rs1042522), and KEAP1 mutations were found to be associated with poor pathologic response to neoadjuvant chemoradiation treatment. KEAP1 mutations, PIK3CA-SOX2 co-amplification, TERC copy number gain, and TYMS polymorphism correlated with an increased risk of disease relapse. Conclusion We report the genomic profile of locally advanced cervical cancer patients and the distinction between Asian and Caucasian cohorts. Our findings highlight genomic traits associated with unfavorable neoadjuvant chemoradiation response and a higher risk of early disease recurrence.

Thanks to the support of relevant national policies since 2018, Internet hospitals in China had developed rapidly. The authors sorted out the current situation of Internet hospital management and construction in China through policy document search and literature search, and found such loopholes as lack of unified supervision and process supervision, barriers between online and offline one-stop services, obsolete information interoperability and network security technology, and poor doctor-patient satisfaction and treatment efficiency. It is recommended to establish a provincial-level standardized supervision and evaluation system, explore an integrated online and offline medical service system, improve the hospital informationized operation guarantee system, promote the improvement of doctor-patient communication satisfaction system, and further promote the development of Internet hospitals in China.

Objectives:To investigate the effect of resistance exercise(RE)on the dissolution of catheter-associated thrombus(CRT)and its possible mechanism.Methods:A total of 36 male SD rats were randomly divided into control group,CRT group,CRT+ RE group(n=12 in each group).Rats in the CRT group did not receive any intervention,while rats in the CRT+RE group received RE intervention 10 days after modeling for 28 days.The thrombolysis rate was evaluated by Hematoxylin-Eosin staining.The contents of irisin,interleukin(IL)-6 and IL-10 in serum were detected by ELISA.The relative mRNA expression levels of peroxisome proliferator-activated receptor γ coactivator α(PGC-1α)and fibronectin type Ⅲ domain-containing 5(FNDC5)in gastrocnemius were detected by real-time quantitative PCR(qPCR).Results:There was no thrombosis in control group.Compared with control group,the contents of irisin and IL-10 in CRT group were significantly decreased,while the content of IL-6 in CRT rats was significantly increased(all P<0.01).Thrombolysis rate was significantly higher,and the mRNA expressions of PGC-1α and FNDC5 in gastrocnemius were significantly upregulated in CRT+RE group than in CRT group(all P<0.01).Serum irisin,IL-10 contents were significantly increased,IL-6 content was significantly lower in CRT+RE group than in CRT group(all P<0.01).Conclusions:Resistance exercise for 28 days could promote the dissolution of CRT,which may be related to the up-regulation of irisin expression and the inhibition of inflammation.
