Objective To observe the clinicopathological characteristics of pulmonary sclerosing hemangioma(PSH) and to analyze its expression and significance in immunohistochemistry,in order to improve the understanding and diagnostic level of this diesease. Methods The clinicopathological features of 6 patients with PSH in Whenzhou Center Hospital from January 2011 to May 2015 were analyzed.Using immunohistochemical methods,the expression of NapsinA,P63, TTF-1,EMA,CK,Vimentin,SP-B,CgA,Syn,CD34 and MC were observed. Results PSH exhibited the following histo-logical features:papillary,solid,hemorrhagic,sclerotic,and mixed.The majority of tumors showed a mixed pattern of histology. The tumor was composed of two distinct cellular components,the cuboidal or surface cells and the round or polygonal or stroma cells.Immunohistochemical staining revealed the both kinds of cells expressed TTF-1 and EMA,the cuboidal cells expressed NapsinA, P63, CK and SP-B,the round or polygonal cells expressed Vimentin.Neither of these two types of cells expressed MC,CD34 and Syn.Sporadic expression of CgA was observed in one case. Conclusion PSH is a rare lung tumor,with various histologie appearance,and often misdiagnosed as lung cancer. The immunohistochemical detection not only suggested that the tumor originates from the multiple potential of the primary respiratory epithelium, but also had important value in the diagnosis and differential diagnosis of PSH.

OBJECTIVETo explore the diagnostic value of ThinPrep cytology test (TCT) in lung cancer.

METHODS353 cases of bronchoalveolar lavage fluid (BALF) and(or) bronchial brushing cytology (192 cases from lung cancer patients and 161 cases from benign lung disease patients) were detected with TCT and method of direct smear, respectively. The sensitivity and specificity of two methods was compared.

RESULTSThe sensitivity and specificity of TCT were 39.6% and 99.4%. And which of direct smear method were 8.3% and 100%, respectively. The sensitivity of TCT was significantly higher than that of method of direct smear in the diagnosis of lung cancer (P < 0.01). There were 71 patients who underwent BALF and bronchial brushing cytology simultaneously, the sensitivity of TCT of BALF was higher than that of bronchial brushing cytology (P < 0.05). Of the 69 cases which had both TCT and histopathological results, TCT and pathology concordance rate was 84.1%.

CONCLUSIONTCT has more diagnostic value in lung cancer; BALF is more preponderant than bronchial brushing cytology by TCT in the diagnosis of lung cancer.

OBJECTIVETo investigate the effect of obstructive sleep apnea syndrome (OSAS) on blood lipid and blood glucose in elderly hypertensive patients.

METHODa One hundred and seven elderly hypertensive patients received examinations by polysomnography and according to the apnea-hypopnea index (AHI), the patients were divided into four groups, namely uncomplicated hypertension group (n=23) and 3 hypertension groups with mild (n=31), moderate (n=29) and severe (n=24) OSAS. The fasting and 2-hour postprandial plasma glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), Apo-A, and Apo-B of these patients were measured.

RESULTSaCompared with the non-OSAS patients, all the OSAS patients showed increased fasting and 2-hour postprandial plasma glucose, HbA1c, TC, TG, LDL and TC/HDL, and the increments were statistically significant in severe OSAS patients (P<0.05). The level of HDL was lowered in the OSAS groups, showing significant difference between severe OSAS group and the non-OSAS group (P<0.05). Apo-A level was lowered and Apo-B increased in the OSAS groups, but the differences were not statistically significant (P>0.05).

CONCLUSIONSOSAS may produce harmful affect on the blood glucose and blood lipids in elderly hypertensive patients.

OBJECTIVETo investigate the effects of platelet factor 4 (PF4) on the adherence, and the expressions of adherent molecules CD(49d) and CXCR4 and the receptor of SDF-1 of fresh and expanded cord blood CD(34)(+) cells.

METHODSCD(34)(+) cells were isolated from cord blood using MACS immune magnetic beads. The adherent ability was assayed by using crystal violet staining and the expression of adherent molecule CD(49d) and CXCR4 by FACS.

RESULTS(1) PF4 could increase the adherent ability of the fresh cord blood CD(34)(+) cells, the effect being positively correlated with the dose of PF4. (2) SDF-1 at concentration of 100 ng/ml increased the adherent ability of the fresh cord blood CD(34)(+) cells. (3) The spontaneous and the SDF-1 induced adherent ability of the cord blood CD(34)(+) cells began to decrease after being cultured for 10 days without PF4, while in the presence of PF4 at 100 ng/ml, the ability of the cord blood CD(34)(+) cell adhering to the stroma layer still remained at higher level. At day 14, the adherent ability was (262.04 +/- 64.81)% and (64.35 +/- 8.29)% in PF4 group and control group, respectively, if it was defined as 100% at day 0. SDF-1 at concentration of 100 ng/ml induced adherent ability was (138.31 +/- 32.39)% and (67.66 +/- 12.44)% in PF4 group and control group, respectively. (4) The expression of CD(49d) and CXCR4 increased 13.02% and 17.33%, respectively, when incubated with PF4.

CONCLUSIONSPF4 could increase the adherent ability and promote the expression of CD(49d) and CXCR4 of the cord blood CD(34)(+) cells, suggesting that PF4 promote the circulating stem cells homing to the marrow in the process of stem cells transplantation.

BACKGROUNDPalliative chemotherapy has been shown to have a survival benefit for patients with recurrent or metastatic gastric cancer. We conducted a Phase II trial to determine the efficacy and safety of S-1 plus oxaliplatin (SOX regimen) as first-line chemotherapy for patients with unresectable locally advanced or metastatic gastric cancer.

METHODSEligible patients had measurable lesions and no previous history of chemotherapy (except adjuvant chemotherapy). Oxaliplatin was administered intravenously at a dose of 130 mg/m(2) on day 1. S-1 was administered orally in doses of 80, 100, or 120 mg/d according to body surface areas of <1.25 m(2), 1.25-1.5 m(2), or >1.5 m(2) respectively; the total dose was divided into two daily doses on days 1-14. Treatments were repeated every 3 weeks until disease progression or intolerable toxicity occurred.

RESULTSForty-three patients were enrolled in the study. All were assessable for efficacy and adverse events. The objective response and disease control rates were 55.8% and 76.7% respectively. The median follow-up time was 16.5 months. The median progression-free survival time was 7 months (95% CI, 5.8-8.2 months) and the median overall survival time was 16.5 months (95% CI, 9.7-23.3 months). The one-year survival rate was 54.2%. Major adverse reactions were grade 3/4 neutropenia (9.3%) and thrombocytopenia (20.9%).

CONCLUSIONThe SOX regimen with oxaliplatin at a dose of 130 mg/m(2) was found to be effective and safe as a first-line chemotherapy in Chinese patients with advanced gastric cancer.
