The coronavirus disease 2019(COVID-19), which is caused by SARS-CoV-2, has become a worldwide public health crisis. Published clinical data from China and other countries have shown a much higher risk of developing COVID-19 and dying from the disease among the elderly, especially among those who had preexisting hypertension, cardiovascular diseases(CVD) and diabetes mellitus[1].

Evidence suggests that the deterioration of communication between the sympathetic nervous system and cardiovascular system always accompanies the aging of human and animals. Cardiac sympathetic norepinephrine(NE) transporter(NET) on presynaptic membrane is a predominant component to eliminate released NE in the synaptic cleft and maintains the sensitivity of the β-adrenergic receptor(β-AR). In the present study,we investigated NET and β1-AR mRNA levels and sympathetic nerve density in cardiac sympathetic ganglion and left ventricular myocardium in 2-and 16-month-old rats with Northern blot analysis and immunohistochemistry. The expression levels of NET mRNA,NET protein and β1-AR mRNA in the ganglia or myocardia of 16-month-old rats were markedly reduced by 67%,26%,and 43%,respectively,in comparison with those in 2-month-old rats. Our results also show that aging induces a strong decrease of the catecholaminergic nerve fiber density.

AIM: To investigate whether changes in the frequencyof peripheral natural killer T (NKT) cells were correlatedwith liver disease in patients who had metabolicpredispositions to nonalcoholic fatty liver disease(NAFLD).METHODS: Peripheral blood samples were obtainedfrom 60 Chinese NAFLD patients and 60 age and gendermatched healthy controls. The frequency of peripheralNKT cells was detected by flow cytometry. Clinical andlaboratory data were collected for further analysis. RESULTS: NAFLD patients had a lower frequencyof peripheral NKT cells than healthy controls (1.21%± 0.06% vs 1.62% ± 0.07%, P < 0.001). Furtheranalysis revealed that the frequency of peripheralNKT cells was negatively correlated with body massindex, waist circumference and serum levels of alanineaminotransferase. Logistic regression analysis revealedthat elevated body mass index [hazard ratio (HR):2.991], aspartate aminotransferase levels (HR: 1.148)and fasting blood sugar (HR: 3.133) increased the riskof NAFLD, whereas an elevated frequency of peripheralNKT cells (HR: 0.107) decreased the risk. CONCLUSION: Changes in the frequency of peripheralNKT cells were correlated with NAFLD and a decreasedfrequency of peripheral NKT cells was a risk factor forNAFLD.

Genetic diversity of 18 processing apple varieties and two fresh varieties were evaluated using 12 simple sequence repeats （SSR） primer pairs previously identified in Malus domestica Borkh. A total of 87 alleles in 10 loci were detected using 10 polymorphic SSR markers selected within the range of 5-14 alleles per locus. All the 20 varieties could be distinguished using two primer pairs and they were divided into four groups using cluster analysis. The genetic similarity （GS） of groups analyzed using cluster analysis varied from 0.14 to 0.83. High acid variety Avrolles separated from other varieties with GS less than 0.42. The second group contained Longfeng and Dolgo from Northeast of China, the inherited genes of Chinese crab apple. The five cider varieties with high tannin contents, namely, Dabinette, Frequin rouge, Kermerrien, ***, and *** were clustered into the third group. The fourth group was mainly composed of 12 juice and fresh varieties. Principal coordinate analysis （PCO） also divided all the varieties into four groups. Juice and fresh apple varieties, Longfeng and Dolgo were clustered together, respectively, using both the analyses. Both the analyses showed there was much difference between cider and juice varieties, cider and fresh varieties, as well as Chinese crab apple and western European crab apple, whereas juice varieties and fresh varieties had a similar genetic background. The genetic diversity and differentiation could be sufficiently reflected by combining the two analytical methods.

Beside as precursors of BRs biosynthesis, more and more evidences supported that phytosterols play an important role in plant growth and development. To investigate the effects of phytosterols on the fiber development of upland cotton （Gossypium hirsutum L.） and the molecular base of sterol regulating cotton fiber growth, a homologue of HYDRA1 was cloned from upland cotton （cv. Xuzhou 142） by screening cotton fiber EST database and contigging the candidate ESTs. The GhHYDRA1 encoded a polypeptide of 218 amino acid residues and the deduced amino acid sequences had high homology with the members of HYDRA1 in Populus trichocarpa, Solanum tuberosum, and Arabidopsis thaliana. Moreover, GhHYDRA1 had comparable transmembrane regions to AtHYDRA1 in sequence, length, order, and spacing, except for a C-terminal polylysine cluster. Quantitative real-time RT-PCR analysis revealed that the higher expression levels of GhHYDRA1 gene were detected in 6 to 12 DPA （days post anthesis） fibers, while the lower levels were observed in 0 DPA ovule （with fibers） and 16 to 18 DPA fibers. These results indicated that GhHYDRA1 is the homologue of HYDRA1 gene and plays a crucial role in fiber elongation. Furthermore, auxin and BL up-regulated the expression level of GhHYDRA1 while ABA and KT down-regulated the expression level of GhHYDRA1 in cotton ovule and fiber growth. The result suggested that phytosterols play a role in the interaction of plant hormones.
