The oncogenic impact of RNF2 on cell proliferation,invasion and migration through EMT on mammary carcinoma

Mammary carcinoma (MC) is one of most common malignancy in women, and ring finger protein 2 (RNF2) possesses various roles in vast human tumors. In MC tissues as well as in cell lines RNF2 exhibited high expression, had significant association with tumor size, lymph node status, TNM stage, patients’ poor survival, and promoted cell proliferation, colony formation, cell migration and invasion of MC cell lines which was mediated by downregulation of E-cadherin protein. These data reveal that RNF2 protein plays a vital role in the development of MC and may be a potential therapy target of MC.     

不同容积布比卡因腹横肌平面阻滞用于腹股沟斜疝患儿术后镇痛的效果

目的探讨使用相同浓度不同容积的布比卡因行腹横肌平面阻滞对患儿腹股沟斜疝患儿术后镇痛作用的影响。方法择期行腹股沟斜疝修补术的患儿120例,男95例,女25例,年龄1～6岁,体重8.3～26.5 kg,ASAⅠ级。随机分为四组,三组使用浓度为0.15%的布比卡因,按不同容积分为0.4 ml/kg组(V4组)、0.5 ml/kg组(V5组)、0.6 ml/kg组(V6组);一组使用2%的利多卡因进行局部浸润麻醉(V0组)。采用儿童疼痛行为量表评估术后即刻(T_0)和术后1 h(T_1)、2 h(T_2)、6 h(T_3)的疼痛程度。当儿童疼痛行为量表评分5分时,静脉注射芬太尼0.25μg/kg补救镇痛。记录术后1 h追加芬太尼的例数。结果与V6组比较,T_2—T_3时V4、V5、V0组儿童疼痛行为量表评分明显升高(P0.05);与T_0时比较,T_2—T_3时V4、V5、V0组儿童疼痛行为量表评分明显增高(P0.05),T_3时V6组儿童疼痛行为量表评分明显增高(P0.05)。与V0组比较,V6组术后1 h内追加芬太尼的例数明显减少(P0.05)。结论儿童患者腹股沟疝修补术使用0.15%布比卡因行TAPB时,在有效剂量和安全剂量范围内,布比卡因的容积更大,术后1 h内镇痛不足的比例减少,术后6 h内镇痛作用持续时间较长,镇痛效果更好。     

A Case of Mayer-Rokitansky-Küster-Hauser Syndrome Diagnosed in Infancy after Evaluation of Palpable Gonads

BackgroundMayer-Rokitansky-Küster-Hauser (MRKH) syndrome is defined as incomplete development of Müllerian structures (uterus, fallopian tubes, proximal vagina) in an otherwise phenotypic female individual. MRKH syndrome typically presents in adolescence with primary amenorrhea, but has been diagnosed in younger patients who present with other associated abnormalities, most commonly renal and skeletal.CaseHere we describe a 46,XX female infant with prenatally diagnosed renal anomalies who was found to have bilateral inguinal ovarian hernias at 1 month of age. Imaging of the genitourinary system revealed absence of the uterus and proximal vagina, consistent with MRKH syndrome.Summary and ConclusionsThis case highlights the importance of a thorough physical examination and an interdisciplinary team evaluation of infants with genitourinary anomalies, particularly when there is concern for differences in sexual development.     

Simultaneous metastasized primary unknown signet ring cell carcinoma of the cervical lymph node and mucoepidermoid carcinoma of the parotid gland as double cancers

Lymph node metastasis from signet ring cellcarcinoma (SRCC) primary unknown is extremely rare. We here report a case of primary-unknown SRCC that metastasized to the cervical lymph nodes, co-existing with mucoepidermoid carcinoma (MEC) of the parotid gland as a simultaneous double cancer. A 68-year-old female patient with right swollen cervical lymph nodes consulted our medical center. A diagnosis of bilateral cervical lymph node metastasis and a right parotid tumor was made. After bilateral neck dissection and right parotidectomy, the pathological diagnosis was SRCC of primary unknown with metastasis to the cervical lymph node and MEC of the parotid gland. Examination of the CRTC1/3-MAML2 fusion gene showed no relation between SRCC of primary unknown with metastasis to the cervical lymph node and MEC of the parotid gland. Ten months after the first treatment, there was recurrence in the left neck lymph node, and left neck dissection was performed. Fourteen months after the first treatment, the patient is alive and cancer-free. This case is the fourth report of SRCC with lymph node metastasis, and highlights the value of fusion gene detection to determine relatedness between simultaneous cancers. Moreover, such cases should be closely monitored for the subsequent appearance of distant metastases.     

超声乳化术中联合应用囊袋张力环对不同眼轴长度超高度近视合并白内障患者的临床疗效

目的探讨超声乳化术中联合囊袋张力环植入对不同眼轴长度(axial length,AL)超高度近视合并白内障患者的疗效和安全性。方法选取2016年10月至2019年6月于我院治疗的超高度近视合并白内障患者56例(56眼)。将患者随机分成两组观察组28例(28眼),其中AL为27~<30 mm者12眼,AL≥30 mm者16眼;对照组28例(28眼),其中AL为27~<30 mm者14眼,AL≥30 mm者14眼。观察组超声乳化术中联合应用囊袋张力环植入,对照组术中不植入张力环。术后随访3个月,检测各组患者视力、眼压、角膜内皮细胞计数、人工晶状体偏心量和倾斜度,同时对各组患者进行主观视觉质量量表评分。结果两组不同AL患者术后3个月最佳矫正视力均较术前升高(均为P<0.05);两组不同AL患者间比较差异则均无统计学意义(均为P>0.05)。两组不同AL患者术后3个月眼压和角膜内皮细胞计数均较术前降低(均为P<0.05);两组不同AL患者间比较差异则均无统计学意义(均为P>0.05)。术后1个月和3个月两组不同AL患者各自组间水平偏心量、垂直偏心量及总偏心量比较,差异均无统计学意义(均为P>0.05)。术后1个月和3个月两组27 mm≤AL<30 mm患者组间水平倾斜度、垂直倾斜度及总倾斜度比较,差异均无统计学意义(均为P>0.05)。术后1个月,观察组AL≥30 mm患者水平倾斜度和总倾斜度均低于对照组同级AL患者,差异均有统计学意义(均为P<0.05);垂直倾斜度比较差异无统计学意义(P>0.05)。术后3个月,观察组AL≥30 mm患者垂直倾斜度和总倾斜度均低于对照组同级AL患者,差异均有统计学意义(均为P<0.05);水平倾斜度比较差异无统计学意义(P>0.05)。术后3个月两组患者主观视觉质量评分均高于术前;两组间同级AL患者观察组均高于对照组,差异均有统计学意义(均为P<0.05)。术后随访3个月,两组患者均未发生眼压升高、角膜内皮失代偿、人工晶状体脱位、眼内炎、视网膜脱离等并发症。结论超声乳化术中联合应用囊袋张力环治疗超高度近视合并白内障安全稳定,并能获得理想的视觉质量。
