目的 观察2型糖尿病大鼠肝脏组织中circRNA-0003340的表达,并探讨与糖尿病的关系。方法 选取健康雄性SD大鼠30只,随机分为2组,正常对照组（NC组,n=10）与2型糖尿病组（T2DM组,n=20）,检测FPG、FINs、HbA1c、TC、TG、HDL-C、LDL-C、AST、ALT;行腹腔注射糖耐量实验和胰岛素耐量实验,计算胰岛素抵抗指数（HOMA-IR）;HE染色观察胰岛细胞形态;RT-PCR检测大鼠肝脏组织circRNA-000334的表达量。结果 与NC组比较,T2DM组的AST、ALT、FPG、HAb1c、FINs、HOMA-IR、TG、TC、LDL-C均升高（P<0.05）,HDL-C降低（P<0.05）。circRNA-0003340在T2DM组肝脏组织中的表达较NC组肝脏组织中的表达是下调的,差异有统计学意义（P<0.05）。Sperman相关分析示大鼠肝脏组织中circRNA-0003340表达水平与FPG、TG及TC呈负相关（P<0.05）。结论 circRNA-003340的表达水平可能与T2DM大鼠的糖脂代谢密切相关,circRNA-003340在肝脏组织中的表达水平下调可能参与T2DM的发生发展。

Objective To observe the expression of circRNA-0003340 in the liver tissue of type 2 diabetes mellitus （T2DM）rats and to explore its relationship with diabetes．Methods A total of 30 healthy male SD rats were randomly divided into two groups,normal control group（NC group,n=10）and T2DM group（n=20）,and fasting plasma glucose（FPG）,fasting insulins（FINS）,glycated hemoglobin（HbA1c）,total cholesterol（TC）,triglyceride (TG）,high-density lipoprotein cholesterol（HDL-C）,low-density lipoprotein cholesterol（LDL-C）,aspartate aminotransferase（AST）,alanine aminotransferase（ALT）levels were detected．Intraperitoneal glucose tolerance test and insulin tolerance test were performed to calculate the insulin resistance index（HOMA-IR）,HE staining was used to observe islet cell morphology,the expression of circRNA-000334 in rat liver tissue was detected by RT-PCR．Results Compared with the NC group,the T2DM group had increased AST,ALT,FPG,HAb1c,FINs,HOMA-IR,TG,TC,LDL-C（P<0.05）and decreased HDL-C（P<0.05）．The expression of circRNA-0003340 in liver tissue in T2DM group was down-regulated compared with that in NC group,with statistically significant difference（P<0.05）．Sperman correlation analysis showed that the expression level of circ-0003340 in rat liver tissue was negatively correlated with FPG,TG and TC（P<0.05）．Conclusions The expression level of circRNA-003340 may be closely related to the glycolipid metabolism of T2DM rats,and the downward regulation of the circRNA-003340 expression level in liver tissues may be involved in the occurrence and development of T2DM．

本文综述近10年中医传统疗法中通过穴位刺激预防与治疗老年患者骨折术后谵妄的研究概况。术后谵妄是老年患者骨折术后常见的并发症,不仅延长患者住院时间、增加经济负担,同时与骨折术后死亡并发症的发生密切相关。但是本病机制尚未明确,在临床治疗上难以达成共识。针灸等穴位刺激是中医药治疗脑病的独具特色的疗法,近年来有关穴位刺激防治老年骨折术后谵妄的报道越来越多,本文主要探讨不同的穴位刺激方法干预对骨折术后谵妄发生率的影响,包括传统刺激方式如毫针、电针、穴位注射、穴位敷贴和新针疗法如耳针、头针等,认为穴位刺激能够较好预防骨折术后谵妄发生,在治疗上也有较好疗效。以期为进一步临床研究与应用提供参考。

Objective To clarify the current situation of mild cognitive impairment（MCI）in the community elderly in Minhang District,Shanghai,and analyze the interaction relationship between the influencing factors of MCI．Methods A cross-sectional study method was used,and AD8 and CSI-D were used to evaluate the current situation of MCI in the elderly over 65 years old in this district in 2021．SPSS 26.0 software,chi-square test and binary unconditional Logistic regression model were used to analyze the composition of smoking,drinking,chronic diseases and other factors in different detected conditions and the influencing factors of MCI occurrence in the elderly．A factor interaction analysis model was used to analyze the interaction of each variable on the occurrence of MCI．Results The AD8 and CSI-D double-scale evaluation method had high sensitivity．The positive rate of MCI in the community elderly in Minhang District was 26.6%,which was higher than other studies．Younger age（OR=1.09,95%CI：1.04~1.14）,good health mentality（OR=1.67,95%CI：1.15~2.42）were protective factors for reducing MCI in the elderly,occupation type（OR=1.19,95%CI：1.04~1.38）,caregiver type（OR=1.56,95%CI：1.09~2.22）were correlated with the occurrence of MCI in the elderly．There were interaction effects between the total monthly household income and the type of caregivers,whether drinking or not and the type of caregivers on the occurrence of MCI in the elderly（all P<0.05）．Conclusions Maintaining a good attitude can reduce the risk of MCI in the elderly．Different occupational types and types of caregivers are related to the occurrence of MCI in the elderly．Caregivers choosing nanny may increase the risk of MCI in the elderly．

目的 分析不同年龄、不同季节河源市源城区呼吸道感染的病原学情况,指导临床用药。方法 回顾性研究2020年3月—2022年2月2 468例呼吸道感染的住院患儿,取咽部分泌物送广州达安临床检验中心进行呼吸道核酸六项检测并分析结果。包括：肺炎链球菌（Sp）、呼吸道合胞病毒（RSV）、卡他莫拉菌（MC）、流感嗜血杆菌（Hi）、肺炎支原体（LP）、腺病毒（ADV）。结果 （1）2 468例患儿的标本中阳性率52.8%,其中RSV最高,其他依次为Sp、Hi、MC、MP、ADV。而混合感染仅次于RSV。（2）婴儿组和幼儿组以RSV感染为主,在学龄前组和学龄组儿童中,以Sp感染为主,各病原体的混合感染组合很多,一种细菌合并一种病毒多见。（3）秋冬季是河源市源城区呼吸道感染的高发季节,RSV是秋冬季呼吸道感染最主要的病原体。结论 秋冬季节为河源市源城区呼吸道感染的高发季节,RSV为该季节的主要病原体。RSV也是婴幼儿组感染的主要致病菌,随着年龄增大,细菌感染导致的呼吸道疾病逐渐占优势。混合感染在各年龄组中均占比较高,值得临床诊疗的重视。

Objective To analyze the etiology of respiratory tract infection in Yuancheng District of Heyuan City ,which was in different ages and seasons,and to provide guidance of clinical drug usage．Methods Cases of 2 468 hospitalized children with respiratory tract infection from March 2020 to February 2022 were analyzed．The secretion from pharynx was collected and sent to Guangzhou Da’an Clinical Examination Center for six respiratory nucleic acid tests and then the results were analyzed,including Streptococcus pneumoniae（Sp）,respiratory syncytial virus（RSV）,Moraxella catarrhalis（MC）,Haemophilus influenzae（Hi）,Mycoplasma pneumonia（MP）,adenovirus（ADV）．Results The positive rate of 2 468 hospitalized children with respiratory tract infection was 52.8%,of which the highest was RSV,followed by Sp,Hi,MC,MP,ADV．Meanwhile the mixed infection rate was second to RSV．RSV infection was the main infection in infant group and early-aged children group,while in preschool group and school-aged group,Sp infection was the main infection．There were many mixed infection of pathogen,and one bacteria combined with one virus was more common．Respiratory tract infection had high incidence in autumn and winter in Yuancheng District of Heyuan City,RSV was the major pathogen．Conclusions Autumn and winter were the seasons with high respiratory tract infection incidence in Yuancheng District of Heyuan City,and RSV was the main pathogen in these two seasons．RSV was also the main pathogen of infant group infection．But with the increase of children’s age,bacterial infection became the main reason of respiratory tract diseases．Mixed infection accounts for a high proportion in all age groups,which should be valued in clinical diagnosis and treatment．

目的 探讨腹主动脉瘤腔内修复术后瘤体直径和瘤体体积的转归以及与术后内漏的关系。方法 回顾性分析2015年—2020年在我院行腹主动脉瘤腔内修复术的83例患者的临床及影像学资料。测量术前和术后各随访时间点瘤体最大直径及体积。CT评价术后内漏发生情况。定义瘤体（直径/体积）扩张/回缩及瘤体（直径/体积）稳定。以术前瘤体最大直径大小和术后内漏发生情况将患者分组,比较组间各随访时点的瘤体直径和体积转归情况。结果 患者术后平均随访时间24（10~62）个月。以瘤体直径<50 mm及≥50 mm分组,术后各随访时间点2组间瘤体体积及瘤体直径比较均无统计学差异。以术后有无内漏分组,术后各随访时间点组间比较瘤体体积变化比较差异均有统计学意义（P<0.05）,但瘤体直径变化组间比较差异均无统计学意义。结论 主动脉瘤瘤体体积与直径变化并不存在一致性,监测瘤体体积可以发现那些直径变化不明显的瘤体变化;腹主动脉瘤腔内修复术后内漏可能是导致瘤体增大的因素之一。

Objective To evaluate the outcome of aneurysm diameter and volume,and the role of endoleak after endovascular aneurysm repair of abdominal aortic aneurysm．Methods The clinical and imaging data from 83 patients who underwent endovascular repair of abdominal aortic aneurysm in our hospital from 2015 to 2020 were retrospectively analyzed．The maximum aneurysm diameter and volume were measured at the preoperative and postoperative follow-up time points．CT was used to evaluate the incidence of postoperative leakage．The aneurysm（diameter/volume）expansion/shrinkage and aneurysm（diameter/volume）stability were defined．Patients were divided into different groups according to the maximum preoperative aneurysm diameter and the incidence of postoperative endoleak,and the outcomes of aneurysm diameter and volume were compared at established follow-up points．Results The mean follow-up time was 24（10-62）months．There were no statistically significant differences in postoperative aneurysm volume and diameter at follow-up points between the patients with aneurysm diameter <50 mm and patients with aneurysm≥50 mm．There were statistically significant differences in postoperative aneurysm volume between the patients with postoperative endoleak and patients without postoperative endoleak（P<0.05）．However,there were no statistically significant differences in postoperative diameter between the two groups．Conclusions The changes of aneurysm volume and diameter were not closely related,and the detection of aneurysm volume can help to find the aneurysm changes with no obvious diameter changes．The postoperative endoleak after endovascular aneurysm repair may be one of the factors leading to aneurysm enlargement．
