目的 研究CXC趋化因子配体4（CXCL4）、基质金属蛋白酶-9（MMP-9）、微小RNA-24（miR-24）对急性脑梗死（ACI）早期神经功能恶化（END）的预测价值。方法 分别选择2020年1月—2021年6月我院收治的30例ACI早期END患者（ACI+END组）,30例单纯ACI患者（ACI组）,同时期30例健康人群作为对照组,检测受试者CXCL4、MMP-9、miR-24表达情况及存在的相关性,分析血清CXCL4、MMP-9、miR-24表达情况与ACI早期发生END的关系。结果 CXCL4、MMP-9水平在对照组、ACI组、ACI+END组中依次升高,miR-24相对表达量依次降低（P<0.05）。血清CXCL4、MMP-9、miR-24水平在轻度、重度患者中呈升高趋势,miR-24相对表达呈降低趋势（P<0.05）。Logistic回归分析血清CXCL4、MMP-9、miR-24表达异常与ACI早期发生END独立相关（P<0.05）。经Pearson相关性分析发现,CXCL4与MMP-9之间呈正相关（r=0.584,P=0.001）;CXCL4、miR-24之间呈负相关（r=-0.569,P=0.001）,MMP-9、miR-24之间呈负相关（r=-0.567,P=0.001）。ROC曲线显示,与CXCL4、MMP-9、miR-24单项预测相比,三项联合对ACI的关系及对早期END的预测价值较高（P<0.05）。结论 CXCL4、MMP-9、miR-24在ACI发生END时出现异常表达,检测CXCL4、MMP-9、miR-24水平对ACI早期END具有一定预测价值,可尽早制定相关措施干预,提高治疗效率。

Objective To study the predictive value of CXC chemokine ligand 4（CXCL4）,matrix metalloproteinase-9（MMP-9）,microRNA-24（miR-24）in early neurological deterioration（END）of acute cerebral infarction（ACI）．Methods A total of 30 patients with ACI early END（ACI+END group）and 30 patients with ACI only（ACI group）who were admitted to our hospital from January 2020 to June 2021 were selected,and 30 healthy people（control group）who underwent physical examination in our hospital during the same period were selected．Expressions of CXCL4,MMP-9,and miR-24 were detected and their correlations were analyzed,and the relationship between the expressions of serum CXCL4,MMP-9,miR-24 and the early occurrence of END in ACI were analyzed．Results The levels of CXCL4 and MMP-9 were increased in the control group,ACI group and ACI+END group in turn,and the relative expression of miR-24 was decreased in turn,and the differences among the groups were statistically significant（P<0.05）．The levels of serum CXCL4,MMP-9,and miR-24 increased in mild and severe patients,while the relative expression of miR-24 decreased,and the differences between groups were statistically significant（P<0.05）．Logistic regression analysis showed that abnormal expressions of serum CXCL4,MMP-9 and miR-24 were independently correlated with the early occurrence of END in ACI（P<0.05）．After Pearson correlation analysis,it was found that there was a positive correlation between CXCL4 and MMP-9（r=0.584,P=0.001）,a negative correlation between CXCL4 and miR-24（r=-0.569,P=0.001）;a negative correlation between MMP-9 and miR-24（r=-0.567,P=0.001）．The ROC curve showed that compared with the single prediction of CXCL4,MMP-9 and miR-24,the predictive value of the combined prediction on ACI and early END were higher（P<0.05）．Conclusions CXCL4,MMP-9,and miR-24 are abnormally expressed in ACI when END occurs．Detection of CXCL4,MMP-9,and miR-24 levels has certain predictive value for early END of ACI,and relevant measures can be formulated as soon as possible to improve treatment efficiency．

Objective To analyze the clinical diagnosis and treatment of uterine carcinosarcoma and its characteristics,in order to improve the understanding of the disease．Methods The clinical data of a Tibetan woman with uterine carcinosarcoma treated in our hospital was analyzed retrospectively．The databases of China Wanfang,Chinese Medical Journal and PubMed were searched,and the relevant literatures were systematically analyzed to summarize the clinical and pathological characteristics．Results This patient was generally in good condition after operation．The incision was healed and she was discharged．The telephone follow-up found that the patient did not receive re-examination as scheduled in 9 months after the operation,and did not receive postoperative adjuvant treatment．The follow-up situation was unable to obtain．Conclusions Uterine carcinosarcoma is relatively rare in clinic and has no specific clinical manifestations．The diagnosis depends on pathology．It has particularity in pathology and contains two kinds of tissue components：cancer and sarcoma．Treatment refers to high-risk special tissue types of endometrial cancer,but there is a lack of effective treatment means,a variety of comprehensive treatment is needed,and the prognosis is poor．

目的 分析对比肺部受累的惠普尔病与初治菌阴肺结核患者的临床特征,提高对肺部受累的惠普尔病的认识、诊断及鉴别水平。方法 回顾性收集20例肺部受累的惠普尔病为病例组,并随机选取同期56例初治菌阴肺结核患者为对照组进行对比,探讨肺部受累的惠普尔病的临床特征。结果 病例组中老年（>37岁）、急性或亚急性的病程比例高于对照组（P<0.05）。CT影像学中,从病灶分布来看,病例组的病灶分布在下叶的病例比例高于对照组（P<0.05）,病灶分布在上叶的病例比例低于对照组（P<0.05）;从形态上看,病例组中表现为网状病灶、间质性肺炎的比例高于对照组（P<0.05）,病例组中表现为空洞、纤维条索、实性影、结节影、树芽征、肺门淋巴结肿大的比例低于对照组（P<0.05）,而性别、合并免疫力低下疾病、咳嗽、咳痰、发热、咳血、关节痛、腹泻等在组间比较差异均无统计学意义。病例组全部病例的肺泡灌洗液宏基因测序结果显示：惠普尔养障体是唯一菌19例（95.0%）或主要菌1例（5.00%,合并结核菌1序列）,而对照组肺泡灌洗液宏基因测序结果显示：21例（37.5%）检测出结核分枝杆菌（TB）复合群是唯一菌或主要致病菌,18例TB-RNA（+）,15例TB-LAMP（+）。结论 惠普尔病在临床可表现为急性或亚急性病程,好发中老年男性,以发热和（或）呼吸道症状为主,可伴或不伴有腹泻、关节痛;肺部影像学以下肺网状、间质性肺炎改变为主,可以单独累及肺部;与初治菌阴肺结核患者临床症状极其相似。应尽快完善支气管镜检查,肺泡灌洗液的宏基因检测对早期、快速诊断此病尤为重要。

Objective To analyze and compare the clinical features of patients with pulmonary involvement of Whipple disease and primary treated bacteriological negative pulmonary tuberculosis,so as to improve the recognition,diagnosis and differentiation ability of pulmonary involvement of Whipple disease．Methods Clinical features of Whipple disease with pulmonary involvement were investigated by retrospectively collecting 20 cases as a case group,comparing with 56 randomly selected patients with primary treated bacteriological negative pulmonary tuberculosis as a control group during the same period．Results The case group had a significantly higher proportion of older patients（>37 years）,acute or subacute disease courses than the control group （P<0.05）．On CT imaging,in terms of lesion distribution,the proportion of cases with lesions in the lower lobe was significantly more in the case group than in the control group（P<0.05）,and the ratio of cases with lesions in the upper lobe was considerably less than in the control group（P<0.05）．Regarding morphology,significantly more of the case group showed reticular lesions and interstitial pneumonia than the control group（P<0.05）．Significantly fewer of the case group showed cavities,fibrous bands,solid shadows,nodular shadows,tree-bud signs,and enlarged hilar lymph nodes than the control group（P<0.05）．No statistically significant differences existed between the two groups in gender,combined immunocompromising diseases,cough,sputum,fever,coughing up blood,arthralgia or diarrhea. At the same time,the differences of gender,combined immunocompromised disease,cough,sputum,fever,coughing up blood,arthralgia,and diarrhea were not statistically significant．The metagenomic sequencing of alveolar lavage fluid in the case group revealed Tropheryma whipplei as the sole pathogenic bacteria in 19 cases（95%）or the primary pathogenic bacteria in 1 case（5.00%,combined TB 1 sequence）．In contrast,metagenomic sequencing of alveolar lavage fluid in the control group detected Mycobacterium tuberculosis complex as the sole or primary pathogenic bacteria in 21 cases（37.5%）,TB-RNA（+）in 18 cases and TB-LAMP（+）in 15 cases．Conclusions Clinical presentation in Whipple disease can be of an acute or subacute course,preferably in middle-aged and older men,with fever or/and respiratory symptoms,either with or without diarrhea and arthralgia．Its pulmonary imaging dominates with reticular,interstitial pneumonia changes in the lower lungs,which can involve the lungs alone in the disease．At the same time,the clinical symptoms are highly similar to those patients with primary treated bacteriological negative pulmonary tuberculosis．Therefore,it is vital to complete bronchoscopy and metagenomic sequencing of alveolar lavage fluid as soon as possible for early and rapid diagnosis of this Whipple disease．Treatment with sensitive antibacterial drugs can result in significant improvement and save patients' lives．
