理肺消积丸对Lewis肺癌小鼠肿瘤生长的抑制作用

目的:观察理肺消积丸对Lewis肺癌小鼠肿瘤生长的影响作用。方法:将50只小鼠随机分为空白对照组、模型对照组、理肺消积丸组[240μg/(g·d)]、顺铂组[0.5μg/(g·d)]、联合组[理肺消积丸240μg/(g·d)+顺铂0.5μg/(g·d)]。采用皮下接种法建立Lewis肺癌小鼠模型,制备模型次日进行药物干预。2周后分别采用活体成像技术检测小鼠体内肿瘤生长情况,HE染色评价肿瘤组织病理学形态,免疫组化技术观察肿瘤细胞增殖细胞核抗原(Proliferating cell nuclear antigen,PCNA)及人第10号染色体缺失的磷酸酶及张力蛋白同源物(gene of phosphate and tension homology deleted on chromosome ten,PTEN)的表达情况,TUNEL技术评价肿瘤细胞凋亡情况。结果:模型对照组小鼠体内肿瘤增殖明显,肿瘤细胞异型性明显、核分裂象多见,PCNA蛋白表达程度极高,而细胞凋亡率及PTEN蛋白表达量极低。与模型对照组对比,理肺消积丸组的肿瘤生长受到抵制,肿瘤细胞异型性及核分裂象减少,PCNA蛋白表达下降,肿瘤细胞凋亡率升高,PTEN蛋白表达升高,差异均有统计学意义(P<0.05)。而顺铂组和联合组除PTEN蛋白表达较模型对照组差异无统计学意义外,其余指标均有统计学意义。结论:理肺消积丸可显著抑制Lewis肺癌小鼠肿瘤生长,其机制可能与其抑制肺癌细胞增殖、上调细胞凋亡和PTEN蛋白表达有关。     

Retention and survival rate of etanercept in psoriasis over 15 years and patient outcomes during the COVID-19 pandemic: The real-world experience of a single center

There have been a number of investigations of the efficacy and safety of etanercept. This study was performed to obtain long-term drug survival data (ie, time to drug discontinuation) for etanercept, and the reasons for its discontinuation. The study population consisted of patients with psoriatic arthritis and psoriasis followed up by our clinic, registered in the Turkish Psoriasis Registry (PSR-TR) and treated with etanercept for at least 4 weeks between January 1, 2005, and January 31, 2020. The efficacy of etanercept was evaluated in terms of the Psoriasis Area and Severity Index (PASI) 75, PASI 90 and PASI 100 response rates at 12, 24, 36, and 48 weeks, and annually thereafter. The behaviors of the patients with respect to the use of etanercept, and the outcomes of those who continued to use it during the COVID-19 pandemic, were also investigated.     

Efeitos de tramadol,magnésio e cetamina por via intra‐articular sobre a dor pós‐operatória em meniscectomia artroscópica

Objective

Postoperative pain control is important in terms of early recovery and rehabilitation in arthroscopic meniscectomy. For this purpose, we aimed to compare the effects of intraarticular tramadol, magnesium, and ketamine with combinations of pericapsular bupivacaine on postoperative pain and recovery in arthroscopic meniscectomy.

Chest wall metastasis of endometrial cancer: case report and review of the literature

Introduction: Endometrial cancer is the fourth most common female cancer and also distant metastases to the chest wall associated with these tumors are seen less common. Surgical treatment options for metastases of endometrial cancer are limited.

Case: A 57-year-old patient who underwent total abdominal hysterectomy?+?bilateral salpingo oophorectomy and received adjuvant chemotherapy for endometrioid-type adenocarcinoma of the endometrium and tuba is presented. The patient initially presented with pleural effusion 8 years ago and the tumor was detected while during etiologic screening. The patient had no problems after adjuvant chemotherapy and had been living in another city when she presented with a mass on the chest wall measuring 20?×?15?×?12?cm 8 years after the initial diagnosis and distant organ metastasis due to the first surgery was detected. The mass was first thought to be a sarcoma and the tru-cut biopsy revealed a metastatic lesion that was immunohistochemically similar to the first surgical specimen. The mass was resected with a wide radical excision and ‘no touch’ technique. The patient was then discharged with no postoperative complications.

Conclusion: Here in, a case with a distant organ metastasis due to an endometrioid-type adenocarcinoma is presented accompanied by literature data.

妊娠早期胎儿颈部透明层厚度与胎儿预后的前瞻性队列研究

目的探讨妊娠早期胎儿颈部透明层(NT)厚度与胎儿预后的关系。方法收集2015年12月至2018年12月于南京大学医学院附属鼓楼医院行妊娠早期胎儿NT厚度测量的单胎孕妇,共4958例建立前瞻性研究队列,进行妊娠早期胎儿结构超声筛查、妊娠早期血清学筛查、妊娠中期超声筛查及对新生儿出生后28 d的体格检查。根据妊娠早期超声筛查的结果,分为胎儿NT增厚(≥3.0 mm)者167例与NT厚度正常者4791例;将胎儿NT增厚的孕妇,分为胎儿单纯NT增厚者86例与NT增厚合并结构异常者81例。分析不同NT厚度胎儿的预后,并重点对单纯NT增厚与NT增厚合并结构异常胎儿的妊娠结局进行分析。妊娠早期超声筛查发现胎儿结构异常或血清学筛查结果为高风险的孕妇,经绒毛穿刺取样术行染色体微阵列分析(CMA)检测以明确产前诊断。结果(1)胎儿NT厚度正常孕妇的妊娠结局:共4791例孕妇,包括胎儿NT厚度正常且无结构异常者4726例,其中妊娠中期及产后新诊断结构异常83例,4688例活产;胎儿NT厚度正常但结构异常的孕妇65例,其中61例孕妇终止妊娠,4例活产。(2)胎儿单纯NT增厚孕妇的妊娠结局:86例孕妇中,66例(76.7%,66/86)行CMA检测,3例胎儿诊断为21三体综合征;除7例孕妇选择终止妊娠外,余79例行妊娠中期超声检查、新生儿出生后28 d体格检查、新生儿电话随访至6~21个月均未发现发育异常。(3)胎儿NT增厚合并结构异常孕妇的妊娠结局:81例孕妇中,73例(90.1%,73/81)行CMA检测,其中32例的胎儿为染色体非整倍体异常。70例选择终止妊娠,2例妊娠中期自然流产,9例活产。(4)NT增厚是否合并结构异常胎儿的产前诊断结果及预后比较:单纯NT增厚的胎儿染色体非整倍体的发生率为3.5%(3/86),合并结构异常者为39.5%(32/81),两者比较,差异有统计学意义(χ2=32.7,P<0.01);胎儿单纯NT增厚孕妇的健康新生儿存活率为91.9%(79/86),合并结构异常者为9.9%(8/81),两者比较,差异有统计学意义(χ2=112.3,P<0.01)。结论妊娠早期,超声筛查胎儿NT及结构,能提高出生缺陷的产前筛查率。单纯NT增厚胎儿的染色体非整倍体的发生率较低,新生儿健康存活率较高。     

Increased risk of eating disorders in women with polycystic ovary syndrome: a case-control study

Abstract

Data on eating disorders in women with PCOS is insufficient. The objective of this case study was to examine the hypothesis that women with PCOS exhibit more impaired eating than healthy women. Women diagnosed with PCOS under the 2003 Rotterdam Diagnostic Criteria (n?=?40) were compared with a healthy control group (n?=?40). The groups also were divided into two as normal body weight and overweight/obese. The Eating Disorders Assessment Questionnaire (EDE-Q) and the Three Factor Eating Questionnaire (TFEQ-R21), were completed by all participants in order to evaluate eating behaviors in addition to eating disorders. Among the overweight/obese group, the average total and subscale scores of the EDE-Q as well as the total and sub-factor scores of the TFEQ-R21 were higher in women with PCOS compared to controls (p?<?.05). However, this statistically significant result was not shown among the women with normal weight (p?>?.05). In comparison to the controls, the PCOS women displayed higher values of the tool scores indicating abnormal restraint eating, body shape concern and weight concern subscale scores (p?<?.05). This result suggests that the evaluation of eating disorders should be added to routine screening and the monitoring of women with PCOS.
