Objective To explore the correlations between emotions and self-concept in patients with traumatic brain injury. Method The Chinese version of the Positive and Negative Affect Scale and the Tennessee Self-Concept Scale was used to test 178 patients with traumatic brain injury.Results The mean scores on positive and negative emotions were (1.93±0.53) and (2.76±0.61), respectively. The mean score on self-concept was (2.45±0.31). The positive emotions of patients were positively correlated with the level of self-concept and the negative emotions negatively with the level of self-concept (r=0.437and -0.363respectively,bothP<0.01). Conclusions For patients with traumatic brain injury,the negative emotions outnumber the positive emotions and their self-concept was at lower level. Nurses should take measures to improve their positive emotions and reduce their negative emotions in order to improve their self-concept level.

Objective To explore the value of placental alpha-microglobulin-1 in vagina liquid to diagnose premature rupture of membranes. Methods A prospective observational study to initial evaluation included both the standard clinical evaluation for rupture of membranes and placental alpha-microglobulin-1 immunoassay. Rupture of membranes was diagnosed if fluid was seen leaking from the cervical os or if two of the following three conditions were present: pooling of fluid, positive nitrazine test, or feming. Rupture of membranes was diagnosed definitively on review of the medical records after delivery. Results Placental alpha-microglobulin-1 immunoassay confirmed rupture of membranes at initial presentation with a sensitivity of 100% (89/89), specificity of 91% (10/11), positive predictive value of 99% (89/90), and negative predictive value of 100% (10/10),false positive rate of 9% (1/11). Placental alpha-nricroglobulin-1 immunoassay was better than the conventional clinical assessment in confirming the diagnosis of rupture ofmembranes (P<0.01). Conclusion Measurement of placental alpha-microglobulin-1 in cervicovaginal secretions is superior to conventional clinical assessment in the diagnosis of rupture of membranes.

Objectives:To compare the advantage and the disadvantage between the normally inserted central venous catheter(NICC) and the peripherally inserted central venous catheter(PICC). Methods:The patients were divided into two groups by different insertion methods:NICC group and PICC group.The success rate of first insertion point,the time of insertion, the symptom of patients during insertion, the complication of insertion and the rate of catheter septicemia were compared. Results:The group of PICC had a higher rate of successful insertion, a less time of insertion, a less time of insertion, a lower rate of complication, but a higher rate of catheter septicemia,when compared with the group of NICC. Conclusions:①PICC have some advantages being simple in insertion and of less complications.②The PICC patients have more chances to suffer from the catheter septicemia.③Perepheral venous inflammation and veno-occlusion more earily occurr in PICC patients.

Objective Investigate and intervene the psychological health state of clinical trainees in the hospital of Yuxi City, in order to explore the method to improve the psychological health and clinical quality of teaching. Methods From 2009 to 2013, clinical trainees were investigated by SCL-90. Intervention for interns included holding psychological health lectures and making psychological counseling for the serious interns. At the same time, the teachers were trained to carry out two-way intervention between the teachers and clinic interns and to improve clinical interns' psychological health. Results Before the intervention,among 216 interns,34 (15.74%) showed positive. Except fear factor, other factors were significantly different than national norms ( <0.05). After the intervention, among 149 interns, 20 ( 13.42%) showed positive. Obsessive-compulsive symptom, depression,anxiety,hostility, spirit factors and the mean scores were all lower than before ( <0.05),similar to the national norm.Conclusion Clinical trainees have prominent psychological problems. Teaching hospitals should pay more attention to psychological health of them. Intervention is necessary and effective in improving psychological health and quality of teaching.

Objective To evaluate the expression of KAII (CD82) gene inhibited by small interfering RNA (siRNA) in human pancreatic cancer cell line T3. Methods Four sequences of siRNA including A, B,C, D were designed, which were based on the KAI1 gene sequence using online RNA interfering designing software and lentivirus vector was built. Then they were used to transfect T3 cells by liposome 2000 and virus titer was determined. Empty vector containing siRNAd1 lentivrus particle ( MOI =5) was also used to infect T3 cells. The expression of CD82 mRNA was detected by real-time PCR. Results The expression of CD82 mRNA in normal control group, empty vector group, A group, B group, C group, D group were 1. 398 ±0.242,1. 311±0.048, 0. 664 + 0. 093, 0. 345 ± 0. 032, 0. 641 ± 0. 049 and 0. 147 ± 0. 049, respectively, the difference between the expression of CD82 mRNA in empty vector group and that of A, B, C, D groups was significant (P＜0.01 ). Conclusions RNAi was able to inhibit the expression of KAI1 gene CD82 in human pancreatic cancer cell line T3.

Background and purpose: The Writ cell-signaling pathway is the key cellular developmental pathway. Dysregulation of this pathway has been implicated in the initiation and progression of cancer. Adenomatous polyposis coli (APC) is an important tumor suppressor gene of the Writ signaling pathway. The methylation of APC promoter and the accompanying loss of the APC transcript have been shown to occur in a significant proportion of cancers. However, there are few reports on the relationship between cervical cancer and methylation of APC. This study was aimed to investigate the promoter methylation status of the APC genes in cervical cancer and its correlation between clinicopathologic characteristics and the infection of high-risk HPV DNA. Methods: Promoter methylation was evaluated using a MSP (methylation-specific polymerase chain reaction) in 95 cervical cancer tissue specimens and 20 normal controls. The relationship between clinicopathologic parameters and the methylation status was evaluated. Results: The frequencies of promoter methylation of APC in cervical cancer were 56.8%. Cervical cancer had significant higher methylation frequencies than that of the controls (10%, P<0.01). The result showed that the methylation analysis of APC promoter and high-risk HPV DNA testing had good consistency (Kappa=0.348, P<0.001). The promoter methylation of APC was significantly higher in adenocarcinoma (AC) than in squamous cell carcinoma (SCC) (74.1% vs 50.0%, respectively, P<0.05). The larger tumor size, positive lymph node metastasis and positive HPV DNA exhibited an increased promoter methylation frequency for APC (P<0.05). There were no significant associations between the methylation frequencies for APC gene to age, invasion depth, FIGO stage and histological grade. Conclusion: Our results suggested that the promoter methyiation of APC and high-risk HPV DNA testing had good consistency. APC gene promoter methylation was a frequent epigenetic event in cervical carcinoma and had a significant correlation with cancer pathological types.

Objective In order to prevent the infection of Acinetobacter baumannii and use antibiotics rationally,the clinical infection and drug resistant data of multi-drug resistance Acinetobacter baumannii (MRAB)detected in intensive care unit (ICU)of Beijing Friendship Hospital from 2011 to 2013were analyzed.Methods This study is a retrospective study.One hundred and eighty five strains of MRAB were collected from the patients in ICU from January 2011 to December 2013.Identificationand antibiotic susceptibility of strains were determined with Vitek-2 Compact automatic bacteria identification system.The annual infection rate of MRAB was counted.PCR was used to detect the resistance genes.The clinical features of the patients with MRAB were analyzed.The average age,acute physiology and chronic health evaluation (APACHE) Ⅱ score,duration in ICU and mortality ratio of the MRAB patients were compared with the patients without MRAB.Rank-sum test was used to analyze the average age,APACHE Ⅱ score and duration in ICU.Chi-squared test was used to analyze the mortality ratio and annual infection rate.Results The average age [(67 ± 17)vs (59-± 19) years old,Z =-5.365,P =0],APACHE Ⅱ score [(25.68±7.93) vs (17.62±8.39),Z=-14.821,P=0],duration in ICU [(27 ±29) vs (5 ±8) d,Z =-4.342,P =0] and mortality ratio [10.82％ (53/185) vs 28.65％ (147/1 359),x2 =45.92,P =0] of the patients infected by MRAB were significantly higher than those without the infection.The MRAB was found mostly in sputum and bronchial precipitates (83.78％,155/185).Though detection rate reduced yearly and there was a significant reduction in 2013 compared with 2011 [11.07％ (69/469) vs 8.37％ (52/621),x2 =8.755,P =0.003],the drug resistant rate was in high level and did not show any change in the 3 years.OXA-23 and OXA-51 were detected in all MRAB.Conclusions The main drug resistant mechanism of MRAB in ICU is related to OXA-23.More active methods of coutrol and prevention of MRAB should be used in elderly aud severely pneumonic patients.Intensive disinfection and isolation measures can decrease MRAB detection rate.Combined antibiotics should be used in patients with MRAB infection.
