Atrial fibrillation ( AF) is an abnormal heart rhythm characterised by rapid and irregular beating.It is caused by multiple factors and can lead to ischemia-associated thrombosis, heart failure and other complex symptoms. Based on the etiology and characteristics of AF, animal models have 3 main categories including electrical, neurohormonal or vessel-related, and structural remodeling models.New technologies such as microRNA knock-down/overexpression or CRISPR-Cas9 gene editing provide tools for constructing animal AF models and directions in the development of AF thera-peutic strategies.Currently these strategies have largely focused on the cellular and molecular therapeutics rather than tradi-tional invasive electrophysiological methods or antiarrhythmic drugs.With the aid of new tools, progress has been greatly made in a broad range of therapeutic research areas including molecular mechanisms, drug targeting and screening.This re-view summarizes the animal models of atrial fibrillation currently used in studies of the molecular and cellular therapeutics and notes their contributions to this research area.

Objective To investigate the clinical features and human papillomavims (HPV) types in 12 cases of HPV infection characterized by pseudocondyloma of vulvae. Methods Twelve women, who had a history of sexual behavior with non-spouses and presented with pseudocondyloma of vulvae, were included in this study. Tissue specimens were scraped or resected from the lesions of pseudocondyloma of vulvae. PCR-based reverse hybridization assay was performed to determine the genotypes of HPV. Results All the 12 specimens were HPV positive. The reverse hybridization assay generated 13 subgenotypes of HPV, including 3 low-risk genotypes (11, 42 and 43) and 10 high-risk genotypes (16, 18, 31, 33, 35, 39, 51, 52, 58 and 59). All the patients were found to be infected by at least one high-risk genotype. Of the 12 patients, 4 were infected by single type of HPV, 6 by 2 types of HPV, and 2 by 3 or 4 genotypes of HPV. Conclusion The patients characterized by pseudocondyloma of vulvae may suffer from high-risk HPV infection.

Finite element method (FEM) is a method to decompose a large complex problem into several small problems to solve it. With this method, multiple small elements can be used to simulate the real physical system, which greatly promotes the development of biomechanics. Biomechanics has always been a hot research direction in spine surgery, and the finite element method is also widely used in spine biomechanics. It can simulate the healthy spine on the computer and study the stress of normal spine in various states, so as to provide help for the study of basic stress of spine.It can simulate the spinal column of pathological changes and degenerative changes, and study its stress in various scenarios, so as to provide direction for the treatment of diseases. Different surgical methods can be simulated to study the stress of the spine and internal fixation after different surgical methods, so as to select the best surgical method for patients; At the same time, it can also simulate different implants and study the stress of different implants in vivo and in vitro, so as to provide guidance for the selection of intraoperative implants and the upgrading and optimization of implants.This paper mainly discusses the application and progress of finite element method in spine surgery, and provides more references for the future study of spine biomechanics and clinical treatment of spine surgery.

Objective To establish a Juema minipig model of myocardial infarction, to evaluate the clinical indi?ces in the model pigs, and to explore the relationship between gene expression and metabolic decompensation. Methods 13 male Juema minipigs were randomly divided into control (Sham, n=5), myocardial infarction (MI, n=5) and normal control (for evaluating the recovery condition after surgery, n=3) groups. In the MI group, the ligation was done at the left descending coronary artery around the 1/3 distance to heart apex. Four weeks after the surgery, the cardiac function and serum biochemistry was analyzed. The histological changes and gene expression profiles in the myocardium in the peri?infarct area were exanimated. Results Ultrasonic images showed that the infarction was formed, the ejection fraction and fraction shortening were significantly reduced in the MI group ( ~32% and ~40% less than those of the sham group). Histological examination showed that myocardial fibers at the peri?infarct area were broken, dissolved, and there was con?nective tissue hyperplasia with increased neutrophil and lymphocyte infiltration. Microarray analysis revealed that two myo?cardial remodeling and pathology mediating pathways, three inflammation?related pathways, and 8 metabolic pathways ( in?cluding fatty acid, amino acid, and glucose metabolic pathways) were significantly changed. Conclusions We have suc?cessfully established a Juema minipig model of myocardial infarction. The less branches of the left descending coronary ar?tery allow us to establish a stable model by surgery with comparable characteristics in the clinic indices. The results of this study provides useful reference characteristics of an animal model with characteristic changes in the peri?infarct area.

OBJECTIVETo evaluate the accuracy and direct medical cost of different screening modalities of physical examination (PE), mammography (MAM), and high-frequency ultrasonography (US) for breast cancer among Chinese women.

METHODSThis study was designed as a blindly carried outcom parative parallel screening trial for breast cancer among Chinese women aged 35 years or older. Physical examination was conducted with the subjects in the first round of breast cancer screening. The negative cases were followed up approximately 1 year later and moved into the second round of screening. Using the results of biopsies and 1-year follow-up as the gold standards, the accuracy and cost indexes of different screening modalities were calculated. Data were analyzed by McNemar test.

RESULTSA total of 2 471 eligible women were included in this trial, and 14 breast cancers were identified among them. Mammography enabled to detect 11 cancers, high-frequency ultrasonography detected 9 cancers and physical examination detected 8 cancers. Considering the three modalities separately, MAM identified the fewest suspicious cases (52 cases) and detected the most cancers (11 cases). Using US alone at the first stage, followed by MAM when indicated, offered the highest specificity (99.7%)and correct positive predictive value (11.4%), meanwhile the sensitivity was 78.6%, and the mean costs of the screening modality in urban and rural areas were 291, 210 yuan and 886,050 yuan per cancer case detected.

CONCLUSIONSThe strategy of screening with US alone at the first stage, followed by MAM when indicated, may be the most suitable modality of breast cancer detection in most regions of China, but the cost is still too high to develop the breast cancer screening in some low incidence regions with limited health resources.
