外周血单个核细胞中mRNA表达与类风湿关节炎活动度的相关性研究

目的 以28个关节疾病活动度评分(disease activity score in 28 joints,DAS28)为基础对不同活动度群组的类风湿关节炎(rheumatoid arthritis, RA)病人和健康人群进行分析,挑选出RA活动度相关基因,为RA的诊断治疗提供新思路与线索。方法 收集苏州大学附属第一医院风湿免疫科门诊28个不同活动度的RA病人和18个健康人的基本信息并对它们外周血单个核细胞中mRNA水平进行检测,通过生物信息学分析寻找活动度相关基因。结果 筛选出80个单纯与RA活动度相关的基因,36个与RA活动度和发病都有关系的基因。在这些基因中,12个单纯与活动度相关的基因(SOCS3、C12orf44、KIFC1、MRPS18A、GYG1、RAB35、B4GALT5、LRRC41、LILRB4、LILRA5、CR1、PDIA6)与DAS28显著相关(r值分别为0.55、0.53、0.52、0.49、0.44、0.42、0.42、0.41、0.41、0.41、0.40、0.39,P值均<0.05)且呈趋势性下降,与发病和活动度都与相关基因PPIH与DAS28显著相关(r=-0.38,P<0.05)且呈趋势性上升。生物功能聚类发现有四项功能和甲基化相关,一项功能和应激反应相关。蛋白质关联分析显示HIST1H3E、HIST1H4I、HIST1H4F、HIST1H3D和HIST1H3F这五个基因不仅出现在与甲基化相关的功能中,而且在实验、文本挖掘和共表达三个方面都存在相互关系。结论 以DAS28为基础挑选出80个单纯与RA活动度相关的基因,功能分析表明他们大多受到甲基化调控作用,部分与免疫应激反应有关。

Molecular Epidemiological Characteristics of Streptococcus pyogenes Strains Involved in an Outbreak of Scarlet Fever in China, 2011

Objective To investigate molecular characterization of streptococcus pyogenes isolates involved in an outbreak of scarlet fever in China in 2011. Methods Seventy-four 5treptococcol pyogenes involved in an outbreak of scarlet fever were isolated from pediatric patients in the areas with high incidence in China from May to August of 2011. Emm genotyping, pulsed-field gel electrophoresis （PFGE）, superantigen （SAg） genes and antimicrobial susceptibility profiling were analyzed for these isolates. Results A total of 4 different emm types were identified. Emm12 was the most prevalent type which contained four predominating PFGE patterns corresponding to four different virulence and superantigen profiles. Emm12（79.7%） and emml （14.9%） accounted for approximately 94% of all the isolates. The speA gene was all negative in emm12 isolates and positive in emml isolates. All strains were resistant to erythromycin, and 89.4% of them were resistant to erythromycin, tracycline, and clindamycin simultaneously. Conclusion Several highly diversified clones with a high macrolide resistance rate comprise a predominant proportion of circulating strains, though no new emm type was found in this outbreak. The data provide a baseline for further surveillance of scarlet fever, which may contribute to the explanation of the outbreak and development of a GAS vaccine in China.

Increased Nectin-4 levels in chronic ketamine abusers and the relationship with lower urinary tract symptoms

Persistent ketamine use causes susceptibility to addiction and bladder toxicity. We examined the association of lower urinary tract symptoms and levels of Nectin-4, a member of the cell adhesion molecules that is essential for maintaining the urothelium barrier in chronic ketamine abusers. We measured the plasma levels of Nectin-4 in 88 patients with ketamine dependence and 69 controls. Patients with ketamine dependence were assessed for ketamine use variables, psychological symptoms, and lower urinary tract symptoms. We found Nectin-4 levels were increased in ketamine-dependent patients compared to the controls (p < 0.0001). Patients with urinary tract symptoms exhibited lower Nectin-4 levels than those without (p = 0.021). Our results suggest an up-regulation of Nectin-4 following chronic and heavy ketamine use. Patients with ketamine dependence with a compromised upregulation of Nectin-4 are likely to have more severe urinary tract symptoms. The mechanisms underlying the involvement of Nectin-4 in ketamine addiction and bladder toxicity warrant future investigation.     

饮食摄入种类和体力活动与2型糖尿病患者死亡风险的前瞻性研究

目的 探讨2型糖尿病（T2DM）患者饮食摄入种类和体力活动及其联合作用与全因死亡和特定原因死亡风险的关联。方法 2013年12月至2021年12月,对江苏省常熟市、淮安市清江浦区（原清河区）和淮安区纳入国家基本公共卫生服务管理的T2DM患者19 863人开展前瞻性队列研究。死亡信息和根本死因源于江苏省CDC死亡监测系统。利用Cox比例风险回归模型估计T2DM患者饮食摄入种类、体力活动以及联合作用与全因死亡及特定原因死亡风险的关联强度。结果 截至2021年12月31日,研究对象累计随访150 283人年,中位随访时间8.15年,随访期间共死亡3 293人,其中1 124人死于心血管疾病（CVD）,875人死于肿瘤。Cox比例风险回归模型分析结果显示,与摄入0~1种食物的T2DM患者相比,摄入5~9种食物的患者全因死亡风险降低19%［风险比（HR）=0.81,95%CI：0.70~0.94］,CVD死亡风险降低33%（HR=0.67,95%CI：0.52~0.87）。与体力活动Q₁组的T2DM患者相比,Q₄组全因、CVD和肿瘤死亡风险分别降低50%（HR=0.50,95%CI：0.45~0.56）、50%（HR=0.50,95%CI：0.41~0.61）和27%（HR=0.73,95%CI：0.60~0.88）。联合作用显示,与摄入0~2种食物和低体力活动的T2DM患者相比,摄入4~9种食物和高体力活动的T2DM患者全因、CVD和肿瘤死亡风险分别降低55%（HR=0.45,95%CI：0.38~0.53）、56%（HR=0.44,95%CI：0.32~0.59）和40%（HR=0.60,95%CI：0.44~0.82）。结论 饮食摄入种类和体力活动及其联合作用与T2DM患者死亡风险降低相关。     

Phosphorylcholine intranasal immunization with a 13-valent pneumococcal conjugate vaccine can boost immune response against Streptococcus pneumoniae

ObjectiveThis study aimed to investigate whether systemic immunization with a 13-valent pneumococcal conjugate vaccine (PCV13) followed by intranasal (IN) immunization with phosphorylcholine (PC) can boost immune response against Streptococcus pneumoniae.Materials and methodsTwo weeks after the intraperitoneal (IP) injection of PCV13, mice were divided into two groups (mice requiring another IP injection of PCV13 and mice requiring PC-keyhole limpet hemocyanin IN immunization in combination with cholera toxin as a mucosal adjuvant) to compare the magnitude of systemic and mucosal immune responses against S. pneumoniae and PC.ResultsSerum immunoglobulin (Ig) G antibody titer against the vaccine strains of S. pneumoniae was similar between the PCV13 systemic immunization group and PC IN immunization group, while the serum IgG antibody titer against PC was significantly higher in the PC IN immunization group. PC-specific IgA antibody titer in the nasal lavage and PC-specific IgA-producing cell number in the nasal mucosa were also significantly higher in the PC IN immunization group. Induction of PC-specific IgA in the PC IN immunization group enhanced the clearance of bacteria from the middle ear.ConclusionAdditional IN immunization with PC after PCV13 immunization, which is currently conducted under a periodic vaccination program, can produce a booster effect comparable to that achieved by additional systemic immunization as well as PC-specific mucosal immune response, thereby providing protection against S. pneumoniae serotypes not contained in PCV13.
