Purpose To study the clinicopathologic features and immunophenotype of the basal cell adenoma ( BCA) with a focal crib-riform pattern in salivary gland. Methods Four cases of BCA with a focal cribriform pattern were retrospectively analyzed with their clinical findings, histopathology and immunohistochemical staining for CK, CK14, CK8/18, CK19, EMA, CD10, CD117, BCL-2, CDX-2, SMA, S-100, p63, p53, EGFR and Ki-67. Results Four cases of BCA with a focal cribriform structure all appeared as slow-growing neoplasms with good circumscription and lack of infiltrative properties, with capsular invasion but without capsular break-through. There are have at least a 50% area of cribriform structure in tumors under microscope. Immunohistochemical profiles exhibi-ted weak positivity for CK, EMA, CD10, CD117, BCL-2, CDX-2, p53 and EGFR, moderate for CK14, CK8/18, SMA and S-100, and strong for CK19, p63 and Ki-67 index<1%. Conclusions Cribriform type of salivary bacal cell adenoma is relatively rare and has difficulty in distinction from adenoid cystic carcinoma ( ACC) . Clinicopathologic features and immunophenotype are the most relia-ble points for differential diagnosis of BCA from ACC.

Serum Cardiac troponin Ⅰ (cTn Ⅰ) and lactic acid were measured in 128 neonatal patients with hypoxic-ischemic encephalopathy and 38 healthy neonates (control group). Serum cTn Ⅰ and lactic acid levels were higher in neonates with hypoxic-ischemic encephalopathy than those in healthy neonates (P < 0. 05 ); and the differences of these values were also statistically significant between the serious patients and the mild patients (P<0.05). Serum cTn Ⅰ and lactic acid are two sensitive markers for degree of myocardial injury and hypoxia in neonatal patients with hypoxic-ischemic encephalopathy.

Objectives To investigate the clinical features of progressive familial intrahepatic cholestasis type 2 (PFIC2) and to illustrate the importance of genetic diagnosis. Methods The mutations in 27 exons of ABCB11 encoding bile salt export pump (BSEP) were identiifed using polymerase chain reaction (PCR) and direct DNA sequencing in 6 children with suspected PFIC2. The pathogenicity of the newly identiifed mutations were predicted by SIFT, PolyPhen-2, SNPs&GO software. The clini-cal features and laboratory examinations were reviewed. Results Four disease-causing mutations, p.R928*, p.E554K, p.R575Q and p.Y337H were identiifed, and the last three mutations were novel. These three kinds of novel mutations can cause the disease. Two children with genetic diagnosis had such manifestations as onset within a month after birth, jaundice, hepatosplenomegaly, upset, increased levels of total bilirubin and direct bilirubin, GGT<100 U/L and high levels of total bile acid. Conclusions Genetic diagnosis is a potent tool for clinical diagnosis of PFIC2.

Objective:To investigate the effect of pidotimod in reducing pulmonary infection in patients with lung cancer undergoing chemotherapy.Methods:One hundred and twenty patients with lung cancer in the Fifth People′s Hospital of Dalian City from July 2017 to July 2018 were selected. The patients were divided into control group and pidotimod group by random digits table method with 60 cases each. The patients were treated with standard two drugs chemotherapy containing platinum drug according to the pathological type, and the patients in pidotimod group were combined with pidotimod. The number of pulmonary infections during chemotherapy, number of completed scheduled chemotherapy and adverse reaction were observed. The correlation between pulmonary infection and pidotimod was analyzed by multivariate orderly Logistic regression.Results:The incidence of pulmonary infection in pidotimod group was significantly lower than that in control group: 18.33% (11/60) vs. 40.00% (24/60), and there was statistical difference ( χ2 = 6.845, P<0.01). The rate of completed scheduled chemotherapy in pidotimod group was significantly higher than that in control group: 55.00% (33/60) vs. 36.67% (22/60), and there was statistical difference ( χ2 = 4.062, P<0.05). Multivariate orderly Logistic regression analysis result showed that pidotimod could reduce the risk of pulmonary infection ( OR = 0.210, 95% CI 0.072 to 0.606, P = 0.004), and help to complete the scheduled chemotherapy ( OR = 2.323, 95% CI 1.080 to 5.003, P = 0.031). In pidotimod group, no obvious adverse reaction related to pidotimod application was detected, and chemotherapy was not affected. Conclusions:Application of pidotimod can reduce the chance of pulmonary infection in patients with lung cancer undergoing chemotherapy and help patients complete scheduled chemotherapy.

OBJECTIVETo investigate the effect of antisense vascular endothelial growth factor (VEGF)(121) cDNA transfection on the growth of K562 cells in nude mice.
METHODSK562 cells transfected with the antisense (AS) or sense (S) VEGF(121) cDNA, and the vector (V, pcDNA3) alone were transplanted subcutaneously into nude mice and the growth of the transfected cells in vivo was investigated. The effects of transfected K562 cells on human bone marrow endothelial cells (BMEC) were analyzed by MTT assay, the microvessel density (MVD) in tumor mass by vWF immunohistochemistry stain.
RESULTSK562/V tumor grew more slowly [(207.5 +/- 192.9) mm(3) vs (445.0 +/- 150.9) mm(3), P < 0.05] and K562/S tumor more rapidly than K562/V tumor did [(1 174.6 +/- 508.7)/mm(3) vs (445.0 +/- 150.9) mm(3), P < 0.01]. K562/S cell culture supernatant was more strongly in promoting the proliferation of BMEC than K562/V supernatant did, but K562/AS supernatant resulted in a marked decrease of the promoting effect as compared with K562/V's. The MVDs in K562/AS, K562/S, and K562/V tumors were [(11.0 +/- 7.6)/0.72 mm(2) vs (50.8 +/- 11.7)/0.72 mm(2) vs (18.9 +/- 7.0)/0.72 mm(2)], respectively.
CONCLUSIONSAntisense VEGF(121) cDNA transfected K562 cells show growth retardation in transplanted nude mice, decrease of tumor MVD, and decrease of promoting BMEC proliferation capacity.
