Objective to analyze the basic situation of university and college teachers′psychological empowerment,and investigate the effect of perceived organizational support,organizational identification,supervisory commitment on psychological empowerment. Methods the instruments which were used include perceived organizational support questionnaire(POS),organizational identification questionnaire(OIQ),supervisory com-mitment scale(SCS)and psychological empowerment scale(PES). A total number of 1 500 teachers were recruited conveniently from 6 university and colleges. Results the average score of psychological empowerment was 60.09±14.21. Positive correlation was found among perceived organiza-tional support,organizational identification,supervisory commitment and psychological empowerment(P < 0.05). Perceived organizational support, organizational identification and supervisory commitment explained 86.5% of variance of psychological empowerment. Conclusion Overall level of university and college teachers′psychological empowerment is in moderate or above degree. Perceived organizational support,organizational identifi-cation,and supervisory commitment can predict a deep level of psychological empowerment.

ObjectiveTo observe the effect of intravesical instillation of Brucea Javanica oil emulsion on recurrence of bladder cancer after transurethral resection of bladder tumor (TUR-Bt) operation.Methods187 patients with superficial bladder carcinoma after TUR-Bt operation were randomly divided into the group A (85 cases) and group B (102 cases). Patients of the group A were treated with instillation of Brucea Javanica oil emulsion; those of the group B were treated with mitomycin. A three-years following up was performed to observe the recurrence and side effects.ResultsAfter a 3-years following up, the recurrence rate of group A was 12.94%, lower than that of group B (34.31%). The side effects were seldom seen in the group A.ConclusionThe effect of intravesical instillation of Brucea Javanica oil emulsion to prevent the recurrence of bladder cancer after TUR-Bt operation is favorable.

Objective To investigate the related risk factors for small artery occlusion (SAO) and its 2 subtypes. Methods The clinical and imaging data in 291 patients with first-ever stroke who met the TOAST criteria of large artery atherosclerotic stroke (LAA) or SAO were collected from the Nanjing Stroke Registry Prog-am from December 2009 to November 2010. All the patients were divided into a LAA group (n = 120) and a SAO group (n = 171). The latter was redivided into either a lacunar infarction with ischemic leukoaraiosis (ILA) subgroup (n = 84)or an isolated lacunar infarction (ILI) subgroup (n = 87). The risk factors of the LAA group and SAO group and its subgroups were compared. Multivariate logistic regression analysis was conducted and the independent risk factors were screened. Results The mean age in the SAO group was larger than that in the LAA group. The proportion of the patients with hypertension and the serum homocysteine (Hcy) level were significantly higher than those in the LAA group (all P ＜0. 05). Multivariate logistic analysis showed that the advanced age (odds ratio, [OR] = 1.041,95% confidence interval [CI] 1.02-1.06, P = 0.045), hypertension (OR = 2. 912,95% CI 1. 11-6. 46, P =0. 031) and increased plasma Hcy (OR = 1. 109, 95% CI 1. 11-1. 32, P =0. 001) were the independent risk factors for SAO. The advanced age (OR = 1. 047,95% CI 1.00-1.09, P = 0.043), hypertension (OR = 2. 632, 95% CI 1.08-6.41, P= 0.033) and increased plasma Hcy (OR = 1. 211, 95% CI 1. 11-1. 32, P ＜0. 001) were the independent risk factors for ILA, while the hypercholesterolemia (OR =0. 136, 95% CI 0. 05-0. 37, P ＜0. 001) was the independent risk factor for ILI. Conclusions The advanced age, hypertension and increased plasma Hcy level may play important roles in the pathogenesis of SAO. The hypercholesterolemia is an independent risk factor for ILI, while advanced age, hypertension and increased plasma Hcy level are the independent risk factors for ILA.

OBJECTIVETo explore the theory of "Fei and Dachang being interior-exteriorly related" and the pathogenesis of lung injury by observing changes of inflammatory cytokines and oxygen free radicals in ulcerative colitis (UC) rats.

METHODSTotally 50 healthy male Wistar rats were randomly divided into two groups, the normal control group and the model group, 25 rats in each group. The UC model was established by allergizing colon mucosa combined with TNBS-alcohol (50%) enema. Another 25 rats were recruited as the normal control group. At week 2 and 4 after modeling, the pathomorphological changes of the lung were observed. Furthermore, the contents of tumor necrosis factor alpha (TNF-alpha) and IL-1beta were determined by ELISA. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated with colorimetry.

RESULTSCompared with the normal control group, the pathomorphology of the lung tissue in the model group appeared abnormal at week 2 and 4. Compared with the normal control group, levels of TNF-alpha, IL-1beta, and MDA in the lung tissue significantly increased in the model group (P < 0. 01) and the activities of SOD significantly decreased (P < 0.05, P < 0.01).

CONCLUSIONTNF-alpha, IL-1beta, SOD, and MDA might be common material bases for the large intestine involved in lung disease of UC patients, thus providing a modern scientific basis for the theory of Fei and Dachang being interior-exteriorly related.

The release kinetics research of sustained-release formulations of traditional Chinese medicines (TCM) is an inalienable part of the chain of TCM modernization, which plays an important role in the development of modern compound TCM preparation. However, the research method or pattern in line with the specific characteristics of TCM, i.e., multi-component and multi-target, is still lacking. On the basis of material rough set theory, this paper reviewed the advantages and disadvantages of the existing evaluation patterns and methods, a tentative idea about the "total amount" release characteristics evaluation on TCM compound sustained-release preparation has suggested so as to evaluate the release kinetics and to promote the development of evaluation methodology on TCM sustained-release preparations.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

Objective The survey aimed to investigate the self-efficacy of permanent colostomy patients at different stages,and explore its impact factors.Methods A total of 267 cases of permanent colostomy patients at different stages (postoperative hospital stay,postoperative chemotherapy and home rehabilitation),coming from many domestic top three hospitals were investigated using the general information questionnaire,C-COH,the Stoma Self-Efficacy Scale,and Perceived Social Support Scale (PSSS).Results The total score of self-efficacy of 267 colostomy patients was (75.97 ± 23.92),ranked in the middle level,and it showed a rising tendency at postoperative hospitalization,postoperative chemotherapy and home rehabilitation.The influencing factors of self-efficacy of the patients at postoperative hospitalization included psychological well-being,BMI and age the regression coefficients were 7.126,1.512 and-0.281.the influencing factors of self-efficacy of the patients at postoperative chemotherapy included psychological well-being,age,the proportion of medical insurance,living state and caregiver,the regression coefficients were 5.182,-0.726,0.238,7.993 and 6.083; the influencing factors of self-efficacy of the patients at home rehabilitation included spiritual well-being,social support,self-care degree,gender and the monthly cost of ostomy supplies,the regression coefficients were 7.215,-7.820,-9.616 and-4.762.Conclusions The influencing factors of self-efficacy of permanent colostomy patients at different stages was different,the medical staff should assess and screen the high-risk factors of self-efficacy positively,according to the individual circumstance and stage,to formulate the individualized intervention measures,so as to enhance the patients' self-confidence to deal with and manage the disease,thereby increasing the level of self-efficacy.

Objective To analyze the magnetic resonance imaging (MRI)and histologic features of the synchronous bilateral primary breast cancer (sBPBC).Methods MRI findings and pathologic types of sBPBC in 20 patients in our institute were reviewed retrospectively. The MRI features of sBPBC were compared with the pathologic types,respectively.Results 20 sBPBC patients with 41 lesions were found with the most common pathological type of invasive ductal carcinoma in 26 (26/41 ).Bilateral lesions had the same pathological types in 1 1 patients(1 1/20),and different types in 9(9/20).The MRI features of invasive breast cancer were more characteristic than that of early breast cancer.In 20 patients,the first and second primary breast cancers with similar MRI findings were found in 6(6/20).In 10 patients with sBPBC,the first cancer was advanced breast cancer,and the second was early or low grade breast cancer.Conclusion (1)The most common pathological type of sBPBC is invasive ductal carcinoma,and the pathological types of bilateral lesions are not similar. (2)The MRI features of the first and the second lesions in bilateral primary breast cancer showed lower similarity,and the bilateral lesions should be diagnosed independently.(3)In patients with sBPBC,some cancers are advanced breast cancers,and the second ones are early cancers,suggesting the lesion should be followed up if the contralateral one is diagnosed as breast cancer.

Human cytomegalovirus (HCMV) is a DNA virus and serious opportunistic pathogen for both newborn and immunocompromised individuals.To research technique for gene silence and antiviral agents, ribozyme M1GS-T6 was constructed from external guide sequences(EGSs)that consist of a sequence complementary to HCMV UL54 gene RNA and M1 RNA, the catalytic RNA subunit of RNase P from Escherichia coli. The results showed that M1GS can efficiently cleave the mRNA sequence encoding UL54 protein in vitro.
