RESUMO
A novel coronavirus disease (COVID-19) caused by SARS-CoV-2 has been pandemic worldwide. The genetic dynamics of quasispecies afford RNA viruses a great fitness on cell tropism and host range. However, no quasispecies data of SARS-CoV-2 have been reported yet. To explore quasispecies haplotypes and its transmission characteristics, we carried out single-molecule real-time (SMRT) sequencing of the full-length of SARS-CoV-2 spike gene within 14 RNA samples from 2 infection clusters, covering first-to third-generation infected-patients. We observed a special quasispecies structure of SARS-CoV-2 (modeled as One-King): one dominant haplotype (mean abundance ~70.15%) followed by numerous minor haplotypes (mean abundance < 0.10%). We not only discovered a novel dominant haplotype of F1040 but also realized that minor quasispecies were also worthy of attention. Notably, some minor haplotypes (like F1040 and currently pandemic one G614) could potentially reveal adaptive and converse into the dominant one. However, minor haplotypes exhibited a high transmission bottleneck (~6% could be stably transmitted), and the new adaptive/dominant haplotypes were likely originated from genetic variations within a host rather than transmission. The evolutionary rate was estimated as 2.68-3.86 x 10-3 per site per year, which was larger than the estimation at consensus genome level. The One-King model and conversion event expanded our understanding of the genetic dynamics of SARS-CoV-2, and explained the incomprehensible phenomenon at the consensus genome level, such as limited cumulative mutations and low evolutionary rate. Moreover, our findings suggested the epidemic strains may be multi-host origin and future traceability would face huge difficulties.

RESUMO
Objective@#To study the distribution of natural killer (NK) cells and the CD38 positive subpopulations in different tissues in rheumatoid arthritis (RA) patients and the mechanism of CD38 agonist.@*Methods@#The levels of NK cells, CD38 positive subpopulation and NK cell surface chemokine receptors (CXCR3, CCR5), as well as granzyme B and perforin were detected by flow cytometry in peripheral blood and knee synovial fluid. The isolated cells were then cultured in vitro and divided into 3 groups, namely blank control group, IB4 stimulation group (Anti-CD38 mAb), IL-2 and IB4 co-stimulation group. And the concentration of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in culture supernatants was determined by enzyme linked immunosorbent assay (ELISA). Liposome CD38-siRNA was transfected into peripheral blood lymphocytes of RA patients, and transfection efficiency was detected by reverse transcription-polymerase chain reaction (RT-PCR). The effect of CD38 and CD38-siRNA silencing on the expression of phospholipase C-gamma 1 (PLC-γ1) protein in the peripheral blood lymphocytes of RA was detected by Western blot.@*Results@#The expression of CCR5 and CXCR3 in NK cells in peripercal NK cells of RA was significantly higher than that in normal healthy subjects (P<0.05). The two chemokine receptors (CXCR3, CCR5) were mainly expressed in CD38+ NK cell subsets. The levels of granzyme B and perforin in synovial lymphocytes cells were significantly higher than those in peripheral blood lymphocytes (P<0.05). The secretion of IL-6 and TNF-α in synovial and peripheral blood lymphocytes cells existed significant difference only in IL-2 and IB4 co-stimulation group (P<0.05). The levels of PLC-γ1 protein in the peripheral blood lymphocytes of RA patients was significantly decreased than that in the blank control group after the treatment with CD38-siRNA (P<0.05).@*Conclusions@#The synovial NK cells are more lethal than the peripheral NK cells in the RA patients. CD38 might mediate the phosphorylation of intracellular proteins via the Protain kinase C (PKC) pathway. Blocking CD38 molecules can reduce the phosphorylation level of intracellular proteins. CD38 maybe involved in the mechanism of chemotaxis and killing capability of NK cells.

RESUMO
Using high pressure homogenization method combined with spray-drying, budesonide-loaded chitosan microparticles were prepared and the in vitro release profile was investigated. The microparticles were then blended with lactose using a vortex mixer, influence of mixing speed, mixing time on drug recovery rate and content homogeneity were investigated. Meanwhile, influence of lactose content on drug recovery rate, content homogeneity, powder flowability and in vitro deposition were studied. It turned out that budesonide was released from the microparicles in a sustained manner, with fine particle fraction as high as 46.0%, but the powder flowability was poor. After blending with 10 times of lactose, the drug recovery rate was 96.5%, with relative standard deviation of drug content 2.5%, and fine particle fraction of the formulation increased to 59.6% with good flowability. It's demonstrated that using a vortex mixer, budesonide sustained-release dry powder for inhalation with good recovery and content homogeneity could be prepared, the formulation had good flowability and was suitable for pulmonary inhaling.

Objective To investigate the risk of permanent hair dye use for connective tissue disease ( CTD ) with positive antinuclear antibodies ( ANA ).Methods We conducted a population-based case-control study to analyze 440 CTD patients from the department of our hospital.Four hundreds and forty patients' relatives or friends who were free from any CTD were selected as controls.Patients and controls were matched in sex and age.A face-to-face interview was adopted to finish questionnaires about subjects' demographic data and the use of permanent hair dye.Data about the duration,frequency,times of usage and allergy related to hair dye were collected.Medical history was also reviewed,such as the diagnosis,disease course,primary symptoms,serum tests and organ involvements.Statistical analysis was performed by SPSS 17.0 software using x2 test and Logistic regression.Results The association between the use of permanent hair dye and CTD did not reach statistical significance (OR=1.282,95％CI 0.966-1.700,P=0.085 ),when the relationship of hair dye use with systemic lupus erythematosus (SLE) was tested,the same result (OR=1.092,95％CI 0.795-1.500,P=0.587 ) could be revealed.Conclusion This preliminary study has shown that the use of permanent hair dye couldn't induce the occurrence of CTD.
RESUMO
Objective To explore the influence of social support and coping style on body and mind symptoms of patients with laryngeal carcinoma. Methods SCL-90, SSRS and MCMQ were used for the questionnaire survey of 168 patients with laryngeal carcinoma. Results The result of SCL-90 showed that all items were higher than those of norm in China, except the interpersonal relationship sensitivity and psychotic symptoms. The result of SSRS showed that the total score of social support was higher than that of norm, while the availability of support was obviously lower than that of norm. The result of MCMQ showed that avoidance and submissiveness were used frequently in patients, and avoidance was negatively correlat-ed with the factors of psychology. Conclusions Before the nursing plan and health consultation are set for patients with laryngeal carcinoma, the patients' social support should be used sufficiently, and the effect of coping style on patients' mental health should be evaluated.
