Background: Nurses are the most visible, frontline personnel providing health education to patients. In particular, nurse experience with Pap examinations have the potential to influence women's attitudes toward screening for cervical cancer. However, nurses in Taiwan have lower rates of Pap testing than the general population. Understanding the factors predicting nurse intent to have a Pap exam and Pap exam status would inform interventions and policies to increase their Pap exam uptake. Therefore, the present study was undertaken. Materials and Methods: Data were collected by questionnaire from a convenient sample of 504 nurses at a regional hospital in central Taiwan between August and October 2011 and analyzed by descriptive statistics, confirmatory factor analysis, and logistic regression. Results: Nurse intention to have a Pap exam was predicted by younger age, less negative attitudes toward Pap exams, and greater influence of others recommendations. However, nurses were more likely to actually have had a Pap exam if they were older, married, had sexual experience, and had a high intention to have a Pap exam. Conclusions: Nurses who are younger than 34 years old, unmarried, sexually inexperienced, and with low intention to have a Pap exam should be targeted with interventions to educate them not only about the importance of Pap exams in detecting cervical cancer, but also about strategies to decrease pain and embarrassment during exams. Nurses with less negative attitudes and experiences related to Pap exams would serve as role models to persuade women to have Pap exams, thus increasing the uptake rate of Pap exams in Taiwan.

Objective: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. Methods: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. Results: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. Conclusion: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

Objective: To study the mechanism of effects of AZD1480 on the SKOV3 ovarian cancer cell line. Methods: The MTT method was used to assess cellular proliferation, flow cytometry for cellular apoptosis, the scratch test to determine migration, transwell chamber assays to detect cellular invasion, plate clone experiments to detect the clone forming ability and Western blotting to determine p-STAT3 protein levels. Results: The proliferation rate, migration ability, invasiveness and the clone forming ability of SKOV3 cells were reduced after treatment with AZD1480, while apoptosis rate and chemotherapeutic susceptibility were increased. After treatment with AZD1480 plus cisplatin, the apoptosis rate increased significantly while the expression level of p-STAT3 protein was decreased. Conclusion: AZD1480 can inhibit the proliferation, invasion, metastasis and clone formation of SKOV3 cells, induce cellulsar apoptosis, increase the chemotherapeutic sensitivity and reduce the expression level of p-STAT3 protein.

Previous studies have demonstrated that JMJD2A is a potential oncogene and is overexpressed in human tumors. However, its role in the endometrial carcinoma remains largely unknown. In this study, we discovered that JMJD2A was overexpressed in endometrial carcinoma, using immunohistochemistry, quantitative realtime polymerase chain reaction, and western blotting. Downregulation of JMJD2A led to reduced endometrial carcinoma RL95-2 and ISK cell proliferation, invasion and metastasis as asessed with cell counting kit-8, cell migration and invasive assays. Collectively, our results support that JMJD2A is a promoter of endometrial carcinoma cell proliferation and survival, and is a potential novel drug target.

Salvianolic acid B (SalB) is an active component isolated from Chinese herbal medicine Salvia miltiorrhiza. The aim of this study was to investigate the extent of absolute oral bioavailability (F) of SalB in beagle dogs and the effect on blood viscosity after intravenous and oral administration of Salvianolic acids (SAs). A gradient elution HPLC method was developed and validated to determine the concentration of SalB and its three possible metabolites in plasma. After SAs (180 mg/kg, p.o.; 9 mg/kg, i.v.) were given, the AUCs of SalB were 1680 ± 670 and 7840 ± 1140 ng/mL·h, respectively. The F of SalB in dogs was calculated to be only 1.07 ± 0.43%. The blood viscosity was remarkably decreased after a single intravenous injection of SAs (9 mg/kg). However, no significant change of blood viscosity was observed after a single oral administration of SAs (180 mg/kg). The results suggested that the F of SalB was extremely low and single oral administrated SAs had no effect on ameliorating blood viscosity in beagle dogs.

Yunnan Baiyao is a famous Chinese medicine that has long been directly applied to wounds to reduce bleeding, pain, and swelling without causing infection. However, little is known about its ability to prevent infection. The present study aimed to assess in vitro the anti-virulence activity of an aqueous extract of Yunnan Baiyao (YBX) using Pseudomonas aeruginosa as a pathogenic model. We found that a sub-MIC (2.5 mg/ml) of YBX can efficiently interfere with the quorum-sensing (QS) signaling circuit. Real-time polymerase chain reaction analysis showed that a sub-MIC of YBX downregulated the transcriptions of lasR, lasI, rhlR, and rhlI,which resulted in global attenuation of QS-regulated virulence activities, such as biofilm formation, and secretion of LasA protease, LasB elastase and pyocyanin. Further, YBX reduced the motility of P. aeruginosa related to QS, and impaired the formation of biofilms. These results suggest that YBX may possess global inhibitory activity against the virulence of P. aeruginosa and that YBX may also exhibit antimicrobial activity in vivo. The present study suggests that Yunnan Baiyao represents a potential source for isolating novel, safe, and efficacious antimicrobial agents.

Plk 1 is overexpressed in many human malignancies including laryngeal carcinoma. However, its therapeutic potential has been never examined in laryngeal carcinoma. In the present study, a simple cellular morphology-based strategy was firstly proposed for rapidly screening the effective siRNAs against Plk1. Furthermore, we investigated the effects of Plk1 depletion via a novel identified effective siRNA against Plk1, Plk1 siRNA-607, on human laryngeal carcinoma Hep-2 cells. The results indicated that Plk1 siRNA-607 transfection resulted in a significant inhibition in Plk1 expression in cells, and subsequently caused a dramatic mitotic cell cycle arrest followed by massive apoptotic cell death, and eventually resulted in a significant decrease in growth and viability of the laryngeal carcinoma cells. Taken together, our present study not only suggests a simple strategy for rapidly screening effective siRNAs against Plk1 but also implicates that Plk1 may serve as a potential therapeutic target in human laryngeal carcinoma.
