To introduce the approaches and procedures of neurologic erectile dysfunction (ED) assessment in our institute, and evaluate the neurologic investigation by making an analysis of 58 cases. Diagnostic criteria of neurologic ED: nervous system injuries or diseases, abnormal clinical symptoms and signs, electrophysiological abnormalities of nervous system, abnormal results of nocturnal penile tumescence and rigidity (NPTR) (penis rigidity <60% and lasting time <10 minutes). In the group of 20 patients with the injuries of the brain, spinal cord or spinal root nerves, pudendal cortical somatic evoked potential (PCSEP), sacral reflex latency (SRL), pudendal-to-cortical motor evoked potential (PCMEP), penile sym- pathetic skin responses (PSSR) and NPTR showed abnormality by 45%, 20%, 20%, 85% and 85%, re- spectively. In 38 patients with the injuries of pelvic fracture with urethra break, PCSEP, SRL, PCMEP, PSSR and NPTR showed abnormality by 24%, 5%, 20%, 92% and 66%, respectively. In the former, 35% were identified to have severe ED, and 50%, moderate ED; in the latter, 21%, to have severe ED, 13%, medium ED, and 37%, light ED. The approaches and procedures were proved to possess excellent specificity and reliability in the assessment of neurological ED.

The occupational hazards to nurses are important factors which may influence the physical and mental health of nurses, and further more influence the quality of care the nurses providing to patients. This article reviewed the occupational hazards to nurses and the related factors in organizational environments and nursing human resources, so as to provide references for further studies and evidence for taking measures to prevent occupational hazards to clinical nurses.

Objective To learn the psychological needs of the hospital staff in terms of their life,medical care and psychological health.Methods 2910 hospital staff were interviewed with questionnaires and the outcomes analyzed with x2 test and descriptive analysis.Results 96.9％of the surveyed found themselves in need of psychological counseling; considerable consulting needs of the staff; most of them turn to friends to complain instead of their leaders.Conclusion The psychological counseling should be enhanced to build effective communication channels and ease stress of the staff.

Background and purpose:Hepatocellular carcinoma (HCC) is a common malignant tumor of the digestive system in our country, with high fatality, development of HCC and the machine system research and treatment is a primary issue in current study of HCC. To explore the expression ofβ-catenin at different stages in the process of hepatocellular carcinoma carcinogenisis for SD rats induced by chemicals. Methods: The experimental group included 48 male SD rats mice with primary liver cancer induced by diethylnirtosamine/carbon tetrachloride/Ethanol, while 48 normal male SD rats mice were used as the control group. The rats were killed every 3 weeks to collect the specimens and observe the pathological changes by HE staining. The changes ofβ-catenin protein expressions were detected by immunohistochemistry and Western blot respectively. Results:SD rats liver cancer was conifrmed by HE staining after 21 weeks DEN/CCl4/Ethanol induction. Immunohistochemistry showed thatβ-catenin expression level was obviously higher in the experimental group(0.27±0.01) than that of the control group(0.21±0.02) after 3 weeks induction(P<0.05). As time progresses, the expression levels ofβ-catenin kept on rising, and at the 18th(0.30±0.02) and 21th weeks(0.32±0.02), it was significantly higher than that of the earlier liver tissues of the experimental group(P<0.05), Western blot consistent with immunohistochemical results. Conclusion:β-catenin protein expression is different in the normal liver tissue, cirrhosis, liver cancer,β-catenin and the occurrence of liver carcinoma development had close relationship.β-catenin protein in the cell with further accumulation, may active a series of target gene, leading to the formation of liver cancer..

Objective To analyze the clinicopathological characteristics of patients with gastrointestinal malignant tumor in some parts of Hainan province and alien patients outside of Hainan province. Methods Three hundred and fifteen patients who were diagnosed by pathological confirmation were selected in Hainan Branch of PLA General Hospital from Jun 2012 to June 2016, clinicopathological parameters including age, gender, tumor location, cancer cell differentiation, body mass index (BMI), body surface area (BSA), value of preoperative tumor markers, TNM stages, microsatellite state, human epidermal growth factor receptor 2 (Her-2) staining, Ki-67 index and risk factors were collected and compared between local and alien patients. Results In contrast with patients outside of Hainan province, a significant lesser BMI [colorectal cancer: (23 ± 3) kg/m2 vs. (24 ± 4) kg/m2, t=-3.69, P< 0.05; gastric cancer: (21.50 ± 3.15) kg/m2 vs. (23.00 ± 3.61) kg/m2, t=-2.11, P=0.04] and BSA [colorectal cancer:[(1.73 ± 0.18) m2 vs. (1.82 ± 0.18) m2, t=-3.46, P<0.05;gastric cancer:(1.73 ± 0.16) m2 vs. (1.81 ± 0.18) m2, t=-2.09, P=0.04] were found in local patients. Local patients with colorectal cancer were much more younger [(57 ± 13) years old vs. (62 ± 13) years old, t=-2.30, P=0.02], with corresponding elevated positive rate of preoperative CEA (χ2=4.56, P= 0.03), T stages (χ2 = 8.31, P= 0.04) and TNM stages (χ2= 11.19, P= 0.01), however, no such difference was detected in gastric cancer patients (all P>0.05). Conclusions Patients with gastrointestinal cancer in some parts of Hainan province, in particular, colorectal cancer patients, present some exceptional clinicopathological features, which are marked by younger age at diagnosis, low level of BMI and BSA. In addition, preoperative level of CEA would be of important for these patients.

Objective To evaluate the life quality of gastroesophageal reflux disease (GERD) patients. Methods Classify the definite GERD patients by differentiation of symptoms and signs first, and then evaluate their quality of life from physiological function, physiological role, body pain, general health, activity, social function, affection function and mental health with scale SF-36. At the same time, 100 healthy persons were brought into the study as control. Results The life quality of GERD patients decreased, and the body pain, general health, social function and mental health decreased more obviously. Difference also lies among the life quality of patients of different syndromes, and the scores of physiological function, physiological role, general health and mental health show significant differences among the four syndromes. Conclusion The life quality of GERD patients decreased obviously.

Objective The overexpression lung cancer1( OLC1) protein is overexpressed in a variety of human tumors.The purpose of the present study is to determine whether increased expression of OLC1 is associat-ed with colorectal cancer.Methods OLC1 expression was assayed in 150 colorectal cancer tissues by immuno-histochemical staining(IHC).Multivariate and univariate analyses were performed to determine the association between OLC1 expression and prognosis.Results Immunohistochemical results revealed that 107 out of 150 colorectal cancer patients had increased levels of OLC1.OLC1 expression was significantly correlated with UICC stage(P<0.001)and histological differentiation(P<0.001)in colorectal cancer patients.The 5-year overall survival( OS) rates in patients with strong positive and less OLC1 staining were 16.6%and 95.3%,respectively (P<0.0001).Conclusion OLC1 overexpression is an important factor in colorectal carcinoma prognosis and can be an interesting potential novel biomarker for colorectal cancer.
