浅谈乳腺叶状囊肉瘤与乳腺纤维腺瘤超声影像的相关性及临床意义

乳腺纤维腺瘤发病率在乳腺良性肿瘤中居首位,而乳腺叶状囊肉瘤在临床恶性病变中也并不罕见,有的学者报道与乳腺癌之比可达1∶20.国内有些学者认为,叶状囊肉瘤虽然可以由纤维腺瘤经肉瘤变而成,但是也可能开始时就是肉瘤.本文通过对32例经手术病理证实的病例进行回顾分析,以探讨二者超声影像的相关性及临床意义.     

新生儿腹胀98例临床分析

目的：探讨新生儿腹胀的常见原因及治疗、转归。方法：对98例腹胀新生儿进行病因分类、回顾性分析治疗转归。结果：以出院诊断为标准，98例患儿中感染性疾病42例，占42．86％；早产儿生活力低下32例，占32．65％。1～3d痊愈12例，1W内痊愈81例，3例转外科治疗，2例死亡。结论：感染性疾病是新生儿腹胀的主要原因，早产儿尤其体重低下者是腹胀的高危人群。临床医师应高度重视，尽快明确原因，给予及时、合理治疗，以提高新生儿生存率。     

使用便携式微量输液泵持续输注氟尿嘧啶的临床观察及护理

目的：探讨使用便携式微量输液泵在肿瘤化疗中持续输注氟尿嘧啶的应用效果。方法：选取我科2006年3月-2008年7月96例癌症化疗病人按入院先后顺序分为对照组和实验组,每组48例。对照组采用传统的化疗方式,采用浅静脉留置针直接从外周静脉输注氟尿嘧啶（5-Fu）连续5天,每天维持6-8小时。实验组采用浅静脉留置针连接便携式微量输液泵持续泵入氟尿嘧啶（5-Fu）120h～135h,两组均以21天为1个周期,观察两组病人化疗毒副反应发生情况。结果：实验组化疗毒副反应发生率明显低于对照组,平均住院时间明显缩短,两组比较差异有统计学意义（P〈0.01）。结论：使用便携式微量输液泵持续泵入氟尿嘧啶能减轻病人的毒副反应,缩短住院时间,提高肿瘤病人生活质量,有效减轻护士的工作负担。     

Lipid extract from completely sporoderm‐broken germinating Ganoderma sinensis spores elicits potent antitumor immune responses in human macrophages

Ganoderma sinensis has been used widely in Oriental countries for the prevention and treatment of various diseases including cancer. Previous studies have shown that the lipid extract from Ganoderma exhibits direct cytotoxicity against tumor cells. Here, it is reported that the lipid extract from germinating G. sinensis spores, at lower concentrations that have no direct tumoricidal activity, induce potent antitumor immune responses in human monocytes/macrophages. Upon stimulation with the lipid extract, monocytes/macrophages exhibited markedly increased production of proinflammatory cytokines and surface expression of costimulatory molecules. Conditioned medium from stimulated cells effectively suppressed the growth of tumor cells. Apparently, the lipid extract triggered macrophage activation via a mechanism different from that associated with LPS. Moreover, it was observed that the lipid extract could partially re‐establish the antitumor activity of the immunosuppressive tumor‐associated macrophages. These results indicated that in addition to its direct tumoricidal activity, the lipid extract from G. sinensis spores could exert antitumor activity by stimulating the activation of human monocytes/macrophages.

嵌体与全冠治疗牙间食物嵌塞的临床应用比较

目的:比较嵌体与全冠治疗牙间食物嵌塞的临床操作及修复效果.方法:对纳入标准的78例患者随机分组,分别用嵌体和全冠进行修复并进行随访观察,并对两种方法的临床应用效果进行比较.结果:在对牙龈及牙周保护方面,嵌体与全冠有显著性差异;在边缘密合、重塑邻接关系及牙齿敏感方面,二者无显著性差异.结论:嵌体较全冠修复牙间食物嵌塞临床操作简便省时,更有利于保护牙髓及牙周组织健康,美观经济.     

螺旋CT三期扫描对肝纤维化诊断价值研究

目的探讨螺旋CT三期扫描对肝纤维化的诊断价值。方法对66例经肝穿刺活检病理证实的慢性乙型肝炎肝纤维化患者组和42例正常对照组进行螺旋CT三期增强扫描。根据纤维化程度分期进行影像资料和相关指标的统计分析。结果肝左叶增大,肝表面形态及肝实质密度的改变,脾脏增大,门静脉增宽和侧枝循环的建立等影像学改变,随着肝纤维化严重程度的加重而有统计学差异。本研究显示57例肝纤维化患者螺旋CT三期扫描诊断肝纤维化52例,敏感性91.2%,特异性77.8%。各期肝纤维化分期准确28例,准确率49.1%;准确判断轻度纤维化(S1、S2)或重度纤维化(S3、S4)44例,准确率77.2%,诊断早期肝硬化16例,准确率84.2%。结论螺旋CT三期扫描能判断肝纤维化的程度,而且是动态观察肝纤维化的病程演进和临床随访的有效手段。

胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.
