The abnormal expression of MUC15, a novel cell membrane-associated mucin, has been reported to predict poor survival in several cancers. The aim of the present study was to examine the expression of MUC15 in glioma and its correlation with clinicopathological features, including the survival of patients with glioma. The mRNA expression level of MUC15 was determined by RT-PCR, quantitative RT-PCR (RT-qPCR) and Western blotting in seven normal brain tissues and seven glioma tissues, respectively. The protein expression level of MUC15 was immunohistochemically detected in paraffin-embedded samples of 317 glioma tissues and 115 noncancerous brain tissues. The association of MUC15 expression levels with the clinicopathologic features and the prognosis was analyzed. The results showed that both mRNA and protein levels of MUC15 were significantly increased in glioma as compared with those in noncancerous brain tissue. Moreover, MUC15 overexpression was positively correlated with the advanced clinical stages of glioam patients (P<0.01). Furthermore, MUC15 expression levels were significantly correlated with the progression of glioma (P<0.001). Survival analysis indicated that glioma patients with higher MUC15 expression had a significantly shorter overall and 5-year survival time than those with low MUC15 expression. Multivariate analysis suggested that MUC15 overexpression was an independent factor for prognosis (hazard risk: 3.216; P=0.009). It was concluded that MUC15 is overexpressed in glioma tissues. Its overexpression correlates with tumor progression and it is a potentially unfavorable prognostic factor for patients with glioma.

OBJECTIVE: To investigate the relationship between visceral syndrome differentiation in traditional Chinese medicine (TCM) and the changes of nutrition status or blood gas analysis in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty patients with COPD in stable phase were divided into dysfunction of lung (DL, n=20) group, dysfunction of lung and spleen (DLS, n=16) group and dysfunction of lung, spleen and kidney (DLSK, n=24) group according to syndrome differentiation of TCM. Moreover, the basic electric rhythm, percentage of bradygastria in electrogastrogram (EGG), ratio of actual body weight (ABW) to ideal body weight (IBW) and serum albumin level were determined to evaluate the nutrition status of the patients with COPD. Blood gas analysis was made too. RESULTS: The basic electric rhythm values in the DL, DLS and DLSK groups were (56.20+/-13.24)%, (47.38+/-10.24)% and (41.35+/-10.01)%, respectively. Compared with the DL group, the basic electric rhythm values in the DLS and DLSK groups decreased obviously (P<0.05). The percentages of bradygastria in the DL, DLS and DLSK groups were (45.18+/-18.13)%, (46.31+/-15.83)% and (49.90+/-17.54)%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of ABW/IBW<90% in the DL, DLS and DLSK groups were 50%, 75% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of serum albumin less than 35 g/L were 20%, 37.5% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). PO2 in the DLS group [(63.56+/-15.06) mmHg] and DLSK group [(63.17+/-19.05) mmHg] were decreased as compared with the DL group [(78.15+/-16.63) mmHg] (P<0.05). PCO2 in the DL, DLS and DLSK groups were (42.25+/-12.46) mmHg, (48.60+/-17.60) mmHg and (49.97+/-13.43) mmHg respectively, and there were no differences among the three groups (P>0.05). CONCLUSION: Several dysfunction organs described in TCM were involved in COPD followed by the increased severity, hypoxemia and PCO2. Dysfunction of gastrointestinal tract and malnourishment took place accordingly.

Objective To explore the therapeutic effect and degree of safety in patients aged 80 years or over with non-small cell lung cancer undergoing radical resection. Methods A retrospective survey of 97 elder patients aged 80 years or over, in whom non-small cell lung cancer was pathologically confirmed after partial resection of the lung in Chinese PLA General Hospital from Jan. 2003 to Dec. 2012. The peri-operative features were evaluated, including gender, age, history of smoking, pulmonary function, surgical procedure, histopathologic type, pathologic stage, etc. The relation of the postoperative complications and mortality with the factors mentioned above was analyzed. Results Among all patients, the surgical procedure comprised 36 lobectomies, 31 segmentectomies, and 30 wedge resections. The histopathologic diagnosis showed there were adenocarcinoma in 51 patients, squamous cell carcinoma in 29, large cell carcinoma in 9, adenosquamous cell carcinoma in 6 and neuro-endocrine cell carcinomas in 2. The disease stage was determined as I A in 55 cases, I B in 33, IIA in 7, III A in 2. The post-operative complications (POC) occurred in 14 of 97 patients (14.4%), and the most common complication was cardiovascular complication (9 cases), followed by pulmonary complication (5 cases). Only two patients died to the complications, one of them was post-operative pneumonia and respiratory failure, and the other one was acute myocardial infarction. The survival rate of the 97 patients was 91.7%, 70.2% and 52.8% at 1, 3 and 5 years, respectively, and in the patients with stage I disease, the survival rate was 93.9%, 73.6% and 54.1%, respectively. Conclusion Advanced age is not a contraindication to radical pulmonary resection in patients over 80 years old suffering from early stage non-small cell lung cancer.

Objective To explore the effect of JNK inhibitor SP600125 on expression of JNK/c-jun in liver cells of rats under repeated and sustained high +Gz exposure and its mechanism of the effect. Methods Eighteen inbred adult male Wistar rats were randomly divided into control group, +10Gz group and SP600125 group (n=6). The rats in +10Gz group and SP600125 group were fixed to the rotating arm of a centrifuge with head towards the axis. The increase rate of acceleration was 1G/s with a peak-time of 3 minutes, and the +Gz exposure was repeated 5 times with an interval of 30 minutes. SP600125 was given to rats of SP600125 group 30 minutes before the first centrifugation by intraperitoneal injection. All of the animals were sacrificed 30 minutes after centrifugation. Blood samples were collected from inferior vena cava to determine the plasma level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The expression of c-jun mRNA was determined by quantitative real-time RT-PCR (qRT-PCR). The expressions of p-JNK, JNK, p-c-jun and c-jun protein were determined by Western blotting. The morphological change in the liver tissue was observed after HE staining. Results The plasma level of ALT and AST, expression level of c-jun mRNA and p-JNK, p-c-jun, c-jun protein in the liver tissue of SP600125 group were significantly higher than those of control group (P<0.05), but they were lower than those of +10Gz group (P<0.05). There was no significant difference of JNK protein expression in the liver tissue among 3 groups (P>0.05). HE staining revealed disorganized hepatic cords, irregular liver cells, vacuolar changes, and marked edema of hepatocytes, and collapsed hepatic sinusoids in +10Gz group, but these changes were alleviated obviously in SP600125 group. Conclusion SP600125 could alleviate the liver cell injury in rats under repeated and sustained high +Gz exposure.
