Abstract
This study aimed to investigate the influence of different ratios of taro slices (TS) on the nutritional quality, sensory quality, and shelf life of Chinese pickled and steamed pork belly (CPSPB). The study examined various aspects of CPSPB, including its proximate components, fat oxidation, fatty acid composition, protein hydrolysis, oxidation reaction, and induction period (IP). Additionally, the sensory quality and texture analysis were compared simultaneously. The results showed that the addition of TS to CPSPB significantly improved water and lipid loss (p < 0.05), increased the unsaturated/saturated ratio of fatty acids, and reduced lipid and protein oxidation. Additionally, the incorporation of TS extended the IP and enhanced the shelf life of CPSPB. Particularly, the addition of a specific amount of TS (60%) to CPSPB resulted in the highest organoleptic quality. Therefore, these results emphasize the positive impact of TS on the overall quality of CPSPB, highlighting its potential to enhance the nutritional value, sensory attributes, and shelf life.

Abstract
Objectives The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development. Cite this article: X. Yang, H. Meng, Q. Quan, J. Peng, S. Lu, A. Wang.

Abstract
Decreasing pH due to anthropogenic CO2 inputs, called ocean acidification (OA), can make coastal environments unfavorable for oysters. This is a serious socioeconomical issue for China which supplies >70% of the world's edible oysters. Here, we present an iTRAQ-based protein profiling approach for the detection and quantification of proteome changes under OA in the early life stage of a commercially important oyster, Crassostrea hongkongensis. Availability of complete genome sequence for the pacific oyster (Crassostrea gigas) enabled us to confidently quantify over 1500 proteins in larval oysters. Over 7% of the proteome was altered in response to OA at pHNBS 7.6. Analysis of differentially expressed proteins and their associated functional pathways showed an upregulation of proteins involved in calcification, metabolic processes, and oxidative stress, each of which may be important in physiological adaptation of this species to OA. The downregulation of cytoskeletal and signal transduction proteins, on the other hand, might have impaired cellular dynamics and organelle development under OA. However, there were no significant detrimental effects in developmental processes such as metamorphic success. Implications of the differentially expressed proteins and metabolic pathways in the development of OA resistance in oyster larvae are discussed. The MS proteomics data have been deposited to the ProteomeXchange with identifiers PXD002138 (http://proteomecentral.proteomexchange.org/dataset/PXD002138).

Abstract
Although RNA-Seq is an effective method for identifying and exploring novel functional genes in mammals, it has rarely been applied to study fertility-related genes in the goat. In this study, RNA-Seq was used to screen the estrus ovaries of uniparous and multiparous Anhui white goats (AWGs). In total, 15,890 genes were identified and 2201 of these were found to be differentially expressed between the genetic libraries from uniparous and multiparous goats. Compared to the uniparous library, 1583 genes were up-regulated and 618 genes were down-regulated in the multiparous library. The FER1L4 gene showed the level of highest up-regulation in the multiparous library, while SRD5A2 expression showed the greatest down-regulation. In order to determine the functions of FER1L4 and SRD5A2 in goats, the expression profiles of the two genes in different tissues from AWGs and Boer goats at diestrus were analyzed by quantitative PCR. FER1L4 and SRD5A2 showed tissue specific expression patterns and were highly expressed in ovaries from both AWGs and Boer goats. FER1L4 was more highly expressed in ovaries from multiparous than uniparous AWGs. In contrast, SRD5A2 was expressed at a lower level in multiparous AWGs. These results indicated that FER1L4 and SRD5A2 may be associated with the high fecundity of AWGs.

Abstract
This study aimed to explore the relationship between genetic changes and high-altitude pulmonary edema (HAPE) susceptibility, and to screen for the key single nucleotide polymorphism (SNP) loci in the HAPE-susceptibility gene, by investigating the SNPs occurring in hypoxia-related genes in HAPE-susceptible and control (non-susceptible) populations. This research was conducted on Han recruits, who travelled to the Lhasa plateau (altitude, 3658 m). Ten loci located on ten genes extracted from the HAPE and healthy populations were amplified by polymerase chain reaction, and subsequently sequenced. The investigated genes included those coding for aldosterone synthase 2 (CYP11B2), angiotensin-converting enzyme (ACE), heat-shock protein 70 (HSP70), nuclear factor kappa B (NF-κB), surfactant protein A2 (SP-A2), plasminogen activator inhibitor-1 (PAI-1), nitric oxide synthetase (NOS), vascular endothelial growth factor (VEGF), prolyl hydroxylase (EGLN1), and zinc finger protein A20. The gene distribution of each SNP loci and its correlation with HAPE was analyzed. Statistical analyses of the genotype frequencies of the SNPs revealed significant differences in the ACE (rs4309), EGLN1 (rs480902), SP-A2 (rs1965708), HSP70 (rs1008438), PAI-1 (rs1799889), and NOS (rs199983) expressions between the HAPE and healthy control groups (P < 0.05); therefore, these SNP loci were believed to indicate HAPE susceptibility. HAPE is correlated with multiple- SNP loci. A correlation analysis between genetic polymorphism and HAPE susceptibility revealed that 6 hypoxia-related genes were key sites accounting for HAPE. These findings could help assess the risk of HAPE in populations expressing different genotypes, in order to reduce the occurrence of HAPE.

Abstract
OBJECTIVE The aim of this study was to improve the understanding of FBA in children and to decrease the rate of misdiagnosis, missed diagnosis and morbidity. PATIENTS AND METHODS We analyzed the clinical features and the three-dimensional reconstructed CT images of 590 children with foreign body aspiration (FBA) in the Xuzhou area of the Jiangsu province. RESULTS CT imaging revealed common complications of FBA including emphysema (n = 379), pneumonia (n = 174), and atelectasis (n = 26). The remaining 120 patients had no visible complications on the three-dimensional reconstructed CT images. Serious complications including pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumatorrhachis could also be observed. The types of foreign bodies were diverse: the most common were peanuts and sunflower seeds. The diagnostic accuracy of the three-dimensional CT imaging was high, with a sensitivity and specificity of 99.83% and 99.89%, respectively. CONCLUSIONS 3D CT imaging is an accurate, non-invasive technique to evaluate children with suspected FBA that can help decrease the rate of misdiagnosis and eliminate a delay in treatment for this potentially life-threatening condition.

Abstract
The purpose of this study was to detect chromosomal aberrations and azoospermia factor (AZF) microdeletions in male patients with reproductive problems and to summarize related clinical features to provide reliable information for evaluating prenatal and preimplantation diagnoses. A large cohort of 5083 men with various phenotypes of male infertility was analyzed via G-banding karyotyping, and Origin 8.0 was used to analyze the prevalence of abnormalities. Additionally, patients with azoospermia, oligozoospermia, and oligoasthenozoospermia were analyzed using multiplex polymerase chain reaction to detect microdeletion in the AZF. We identified 387 patients with abnormal karyotypes, and the ratio was 7.61%. Among them were 175 patients with Klinefelter's syndrome, which was the most common numerical chromosomal abnormality and accounted for 45.22% of all chromosomal aberrations. The frequencies of increased satellites, balanced translocations, and Robertsonian translocations were 6.47, 7.00, and 3.62%, respectively. Multiplex polymerase chain reaction performed in 810 cases with azoospermia, oligozoospermia, and oligoasthenozoospermia found a ratio of AZF microdeletions of 4.94%. The finding suggests that chromosomal abnormalities and AZF deletion are main factors that result in male infertility. Detecting these common genetic variations is necessary in infertile men seeking assisted reproductive technology.

Abstract
Four calcium channel blockers, i.e. nifedipine, verapamil, cinnarizine and tetrandrine are currently available and used widely in treating cardiovascular diseases. To confirm the effects, if any, of calcium channel blockers on cirrhotic patients with portal hypertension, a study was performed on esophageal variceal pressure and rebleeding rate of esophageal varices after 2 years by using calcium channel blocker in 321 patients from some 23 hospitals. The results demonstrated that the calcium channel blockers could significantly reduce the esophageal variceal pressure and the portal blood flow in cirrhotic patients with portal hypertension. The proportion of patients with no recurrent gastrointestinal bleeding after 2 years medication of tetrandrine was 87.9% in tetrandrine group, significantly higher than those in the other 4 groups (P < 0.05). It is suggested that tetrandrine should be more effective for cirrhotic patients with portal hypertension in preventing recurrent variceal bleeding.
