Pituitary stalk interruption syndrome(PSIS), as a rare congenital defect manifesting with varying degrees of pituitary hormone deficiency, its diagnosis is frequently delayed in clinical practice for the signs and symptoms during the neonatal period and infancy are often overlooked. The typical features of PSIS can be detected by magnetic resonance imaging. Several genes in Wnt, Notch, and Shh signaling pathways that related to hypothalamic-pituitary development, have been found to be associated with this rare syndrome. Nevertheless, the etiology in the majority of cases still remains unknown.In this review, we provide an overview of clinical features of PSIS and summarize our current understanding of its etiology. Furthermore, we propose future research directions for it.

Objective To study the relationship between the number of examined lymph nodes and the prognosis of colorectal cancer by TNM stage. Methods According to the number of examined lymph nodes, 567 patients of colorectal carcinoma who underwent resection were divided into three groups: ≤ 6,7-11 and ≥ 12, the 5-year overall survival rates of three groups were compared. For each TNM stage ( stage Ⅰ -Ⅳ ) , patients were substratified into two groups basing on the number of examined lymph nodes:<12 group and ≥12 group, the 5-year survival rates of two groups in each TNM stage were assessed, and prognostic factors of stage Ⅱ and Ⅲ stage were analyzed. 5-year survival curves were estimated with the Kaplan-Meier method and compared by the log-rank test. Cox proportional models were used to conduct multivariate analyses of prognostic factors. Results The average number of examined lymph nodes was 16. 75 ±9. 88. With the patients grouped by the number of lymph nodes ( ≤6,7 -11 and ≥12 nodes) , the 5-year survival rate was 32. 3% , 43. 8% , and 57. 7% , the univariable analysis indicated that the 5-year survival rate of ≥ 12 examined nodes were significantly higher than the other groups (P<0. 05). There was no difference between two groups in the 5-year survival rates of stage Ⅰ or Ⅳ colorectal cancer (89. 5% vs.89. 1% ,8. 0% vs. 18. 2% , P>0. 05 ) , however, the 5-year survival rates of stage Ⅱ and Ⅲ colorectal cancer in ≥12 group were significantly higher than<12 group(71. 1% vs. 32. 6% ,48. 8% vs. 30. 0% ,P<0. 05) , multivariable analysis revealed that the number of lymph nodes examined was an independent factor of prognosis of stage Ⅱ and Ⅲ colorectal cancer. Conclusions The number of examined lymph nodes significantly influenced the 5-year overall survival rate of TNM stage Ⅱ and Ⅲ colorectal cancer.

Objective:To observe the color change of tooth i nduced by hydrogen peroxide gel. Method:12 extracted teeth were randomly assigned to two groups (n=6) and treated with 350 g/L and 75 g/L hy drogen peroxide gel respectively. One of the 6 samples in each group was used as the control. The bleaching gel was placed onto the enamel surface of the sample s. In 350 g/L gel group digital photographs were taken just before,10 and 30 min after the process, in 75 g/L gel group digital photographs were taken before an d 1.5?N(N=0,1,2,3,4,5,6,7) hours after the process respectively. All photograph s were taken at the same illuminating conditions and photographic parameters wer e analyzed with Photoshop7.0 software. Results:10.5 h after trea tment in the 75 g/L gel group L *, a * and b * values on the teeth surface were in creased(+) or decreased(-) by +4.5,-1.4 and -0.5,those on the inner sections 2.7 ,-1.0 and -0.8,respectively. 30 min after treatment in the 350 g/L gel group L *, a * and b * values on the teeth surfaces were increased(+) or decreased (-) by +1.9,-0.6 and 0,those on the inner sections +0.4,-0.4 and -0.6,respectively. Conclusion:Effective bleaching effect may be obtained in 10~30 min b y 75 g/L or 350 g/L hydrogen peroxide gel on teeth surface and in inner dentin. 75 g/L hydrogen peroxide bleaching gel may produce more reliable and save effect than 350 g/L.

Objective To evaluate the effectiveness of renal sympathetic denervation (RDN) for hypertensive heart dis-ease combined with systolic heart failure. Methods Two patients (mean age 35 years) with hypertensive heart disease com-bined with systolic heart failure on maximal tolerated heart failure therapy underwent bilateral renal denervation. Echocar-diography, the six minute walk distance, renal function, glycosylated hemoglobin and NT-proBNP were assessed at baseline and 1 year after renal denervation. Results Renal artery angiography showed that no stenosis and dissection. After 1 year follow up, the left ventricular ejection fraction (LVEF), six minute walk distance and NT-proBNP were significantly im-proved, and the size of left ventricular decreased. Conclusion RDN is effective and feasible for the treatment in patients with hypertensive heart disease and systolic heart failure.

Objective:To investigate the clinical characteristics and prognostic factors of primary signet-ring cell adenocarcinoma of lung. Methods:The clinical features of 22 patients with primary signet-ring cell adenocarcinoma of lung from the year 1981 to 2007 were analyzed retrospectively and made a statistical analysis on the prognostic factors. Results:Postoperative pathologic examination was an important method to confirm the primary signet-ring cell adenocarcinoma of lung and surgery was the main therapeutic approach. The 1-, 3-, and 5-year survival rates were 63.0%, 53.3%, and 37.7%, respectively. Statistical analysis indicated that smoking, tumor size, complete resection, and tumor staging were the independent prognostic factors for patients with primary signet-ring adenocarcinoma of lung.Conclusion:The primary signet-ring cell adenocarcinoma of lung has higher malignancy. Invasion and migration frequently occur. Its prognosis is poor.

Objective:To investigate the correlation between the expression of Golgi phosphoprotein 3 (GOLPH3) and the occurrence of apoptosis in colorectal cancer cells (CRC). Methods:Immunohistochemical assays of GOLPH3 and caspase-3 were performed on the paraffin-embedded sections of 62 CRC samples using the standard streptavidin-peroxidase technique. The apoptotic index of the CRCs was examined using the in situ terminal deoxynucleotidyl transferase nick-end labeling technique. The relationship of the GOLPH3 expression, the cell apoptosis, and the clinicopathologic parameters was analyzed. Results:The positive rates of GOLPH3 expression were significantly higher in the CRC tissues (53.2%) than in the normal colorectal mucosa (37.2%;P<0.05). Likewise, GOLPH3 expression was significantly higher in poorly differentiated cancer tissue, tissue outside the serous membrane, metastatic lymph node tissue, and the stage III CRCs, as compared with those of the moderately to well differentiated tissue, tissue inside the serous membrane, lymph node tissue without metastasis, and the stage I to II CRCs (P<0.05). However, GOLPH3 expression was not significantly correlated with the other clinicopathologic pa-rameters, namely, the age and sex of the patients as well as the site, depth, and length of the invasive tumor (P>0.05). The caspase-3 expression and apoptotic index were significantly lower in the GOLPH3-positive CRC tissue than in the GOLPH3-negative tissue (P<0.05). GOLPH3 expression was negatively correlated with the apoptotic index of CRCs based on the Spearman correlation (r=-0.320, P<0.05). Conclusion:GOLPH3 overexpression in CRC tissue is negatively correlated with apoptotic index.

Objective To study the risk factors of severe hand-foot-mouth disease (HFMD) among children.Methods The clinical data of 1 570 children with HFMD at Linyi People's Hospital in Shandong Province in 2011 were collected,retrospectively.The data were analyzed using univariate and multivariate Logistic regression.Results The mean age of severe HFMD (including severe and critical HFMD) was (25.0± 14.0) months old,predominantely aged between 1 and 5 years old,while mild HFMD was (27.1±15.8) months (t'=-2.717,P=0.007).There were 61.0％ and 65.9％ boys in two groups,respectively (x2 =3.894,P=0.048).Fever,convulsion,tremor,nausea and vomiting were more frequently seen in severe HFMD.The neutrophil count and the level of creatine kinase in severe HFMD were both significantly higher than that in mild HFMD.Univariate analysis revealed that age (odds ratio [OR]=1.799,95％CI:0.984-1.997),girl sex (OR=1.234,95％CI:1.001-1.522),high fever (OR=2.110,95％CI:1.816-2.452),convulsion (OR=1.878,95％CI:1.578-2.236),nausea and vomiting (OR=1.760,95％CI:1.456-2.128),neutrophil count (OR=1.031,95％CI:1.025-1.037) and creatine kinase (OR=1.002,95％CI:1.001-1.003) were risk factors for severe HFMD.Multivariate Logistic regression showed that high fever (OR =1.751,95％ CI:1.487-2.062),convulsion (OR=1.451,95％CI:1.204-1.749),nausea and vomiting (OR=1.269,95％CI:1.027-1.568),neutrophil count (OR=1.028,95％CI:1.021-1.035) were independent risk factors.Conclusions Body temperature,neurological manifestations and trend of neutrophil counts should be carefully monitored in children with HFMD.Prevention of the development of severe HFMD mainly relies on the identification of risk factors and adoption of precautions in time.
