Protein Losing Enteropathy in Severe Atopic Dermatitis in an Exclusively Breast-Fed Infant

Abstract:   We first report a case of protein losing enteropathy in severe atopic dermatitis in an exclusively breast-fed 5-month-old infant. Protein losing enteropathy was confirmed by fecal α₁-antitrypsin clearance test and imaged successfully by ^99mTc-human serum albumin scintigraphy. The present case highlights that protein losing enteropathy in severe infantile atopic dermatitis is being a topic of concern and also an issue even in exclusive breast feeding patients.     

丙泊酚对胆道感染患者髓样细胞触发受体-1表达的影响

目的探讨丙泊酚对胆道感染患者外周血髓样细胞触发受体-1(TREM-1)的影响。方法 48例严重胆道感染患者,随机分为两组:丙泊酚处理组(P 组,n=28),术中用丙泊酚6 mg·kg~(-1)·h~(-1)及异氟醚(呼气末异氟醚浓度维持在1%)维持麻醉;对照组(N 组,n=20),术中用异氟醚维持麻醉(呼气末异氟醚浓度维持在2.5%)。上述两组术中均间断静脉注射阿曲库铵、芬太尼维持麻醉.且用量无差异。两组分别在手术前及手术后12、24、48、72 h 留取血液标本,用流式细胞术检测外周血 TREM-1蛋白的表达;用酶联免疫吸附实验法(ELISA)检测血肿瘤坏死因子α(TNF-α)表达水平。结果术前两组患者的 TREM-1及 TNF-α含量差异无统计学意义;P 组患者术后12、24、48、72 h 的 TREM-1及 TNF-α水平均明显低于 N 组(P<0.05)。结论严重胆道感染患者可致外周血TREM-1蛋白高水平表达。丙泊酚可降低 TREM-1蛋白表达水平.减轻炎症反应。

Huge adrenal haemangioma

Adrenal tumours are either functioning or non-functioning. Non-functioning adrenal tumours are generally asymptomatic and usually of enormous proportions at the time of presentation. A case is presented here of a patient with a huge right adrenal haemangioma which was successfully treated surgically. This unusual tumour was 25 cm in diameter, was well encapsulated and weighed 4 kg. The literature pertaining to this interesting case is reviewed.

The effects of alpha M-foetoprotein, an acute phase protein, and BaSO4-induced injury on IgE-mediated, systemic anaphylaxis in the rat

A recently developed method for inducing fatal, IgE-mediated, bronchial and cardiovascular anaphylaxis in the rat was used to compare the effects of exogenously administered, purified alpha M-foetoprotein (alpha M FP) and BaSO4 pretreatment (as mean to induce an acute phase reaction with increased alpha M FP serum levels) with regard to mortality, bronchoconstriction and cardiovascular events. The BaSO4 pretreatment protected the rats almost completely against mortality, whereas exogenously administered alpha M FP offered no protection at all. With respect to the antigen-induced bronchoconstriction alpha M FP greatly inhibited the increase of the pulmonary resistance (RI), whereas the BaSO4 pretreatment suppressed either the dynamic lung compliance (Cdyn) or RI considerably. The cardiovascular events were only influenced by the BaSO4 pretreatment demonstrating a small but highly significant reduction of the initial fall in blood pressure together with a remarkable recovery within almost I h in the majority (91%) of the animals. Both exogenously administered alpha M FP and BaSO4 pretreatment increased the alpha M FP serum levels from a normal value of 59 +/- 4 micrograms/ml (n = 22), to 2732 +/- 252 micrograms/ml (n = 9) and 855 +/- 200 micrograms/ml (n = 22), respectively. From these data we conclude that the antianaphylactic activity of alpha M FP is limited to bronchoprotection of the more central parts of the lungs, whereas BaSO4 pretreatment covers a much broader antianaphylactic profile. This implies that BaSO4 pretreatment does not only induce alpha M FP but also other endogenous antianaphylactic factors.     

雄激素剥夺条件下阻断自噬增加LNCaP细胞凋亡

Objective To investigate the change of apoptosis in LNCaP cells after inhibition of autophagic process under androgen removal conditions. Methods The autophagic level was deter-mined by using confocal microscopy and RT-PCR. The DAPI staining was used to indicate the apopto-sis of LNCaP cells after inhibition of autophagic by 3-MA. Also, Z-VAD-FMK was used to extend the apoptosis results. Results ①Androgen deprivation led to increased autophagy in LNCaP cells. LN-CaP cells cultured in complete medium(CM) presented low autophagic process with 1.9 scores. After 24 hours, the punetate GFP-LC3 structures were accumulated in the cells cultured in serum-free medi-um (SF)(2.64 scores). In contrast, the number of punctate GFP-LC3 remained at a very low level (1.85 scores), when cells were incubated with DHT in SFA(serum-free medium+DHT). Statistical analysis showed the significant difference between SF and SFA (P<0.01). Semiquantitative RT-PCR was employed to examine the mRNA expression of LC3. Indeed, cells grown in the medium without serum had a higher LC3 mRNA expression with the highest at 12 hour time point as compared with the cells grown in CM. DHT treatment reduced the level of LC3 mRNA. ②Blockage of autophagy by 3-MA increased the apoptosis of LNCaP cells. LNCaP cells in SF and SFA just presented a basal level of apoptosis, which is (3.19±1.09)% and (3.01±0.33)% , respectively. Under androgen-free con-ditions, inhibition of autophagy by 3-MA could increase apoptosis significantly(10. 90±2.91%). While Z-VAD-FMK, a pan Caspase inhibitor, was able to suppress this apoptotic process to the level of (1.16±0.52)%, which was statistically significant(P<0.01). Conclusions Androgen removal can lead to the increase of autophagy in LNCaP cells. Moreover, inhibition of autophagy promotes the occurrence of apoptosis.

Lymphoceles: imaging characteristics and percutaneous management

Twenty-five patients who had lymphoceles underwent sectional imaging and interventional radiologic procedures. Viewed using sonography, lymphoceles were hypoechoic to anechoic, occasionally with internal septa and debris. Low numbers (occasionally negative values) were observed using computed tomography (CT); these numbers strongly suggest the diagnosis of lymphocele. Calcification was observed on CT images of one patient. Diagnostic aspiration revealed tan to yellow fluid containing many lymphocytes; pathognomonic fat globules were observed in four cases. Malignant cells were found in two collections, an unusual occurrence. Therapeutic needle aspiration and short-term catheter drainage were usually unsuccessful (only one of five patients [20%] was cured). Long-term (1-5-week) catheter drainage cured 11 of 14 patients (78.6%). Sclerosing agents may have been beneficial for lymphocele obliteration in three of four patients. For most patients, lymphoceles may be diagnosed and treated successfully using radiologic means.
