Objective To investigate the psychological state of high-risk pregnancy mothers af-ter being separated from their newborns and discuss the influencing factors of psychological state. Methods Nonexperimental descriptive study was used in this study. The investigation adopted state-trait anxiety inventory (STA-Ⅰ) and Edinburgh postnatal depression scale (EPDS). Results The moth-ers' anxiety score was significantly higher than normal women in China, and postnatal depression inci- dence rate was 57.9%. Mothers' psychological state was correlated with gestational age of new-borns, trait anxiety and pregnancy complications. Conclusions The psychological state of high- risk pregnancy mothers after being separated from their newborns should be paid more attention to, and cor-related nursing methods should be taken to improve their mental health.

Inhibitor of growth (ING) family proteins belong to candidate tumor suppressor proteins. The ING proteins participate in PtdInsPs-mediated lipid signaling and hormone signaling pathways. They are associated with histone acetyltransferase, histone deacetylase and play a role in chromatin remodeling and gene transcription regulation. ING proteins regulate cell growth, apoptosis and DNA damage repair in p53 dependent manner; thus linking the processes of cell cycle regulation, apoptosis and cellular aging through epigenetic regulation of gene expression.

Objective To explore the clinical significance of determining the levels of plasma TXB 2,PAgT,6-Keto-PGF 1? in the lung carcinoma patients.Methods The levels of plasma TXB 2,PAgT and 6-Keto-PGF 1? were determined in 43 patients with lung carcinoma and 45 healthy controls,and 36 cases of 43 patients with lung carcinoma were randomly divided into two groups:(A) conventional treatment plus warfarin sodium,(B) conventional treatment without anticoagulant.We also determined the level of plasma Fib in both group A and group B,besides examined the levels of plasma TXB 2,PAgT and 6-Keto-PGF 1? before and after treatment.Results Statistical analysis showed that the levels of TXB 2 and PAgT were significantly higher,but the levels of 6-Keto-PGF 1? was significantly lower in the patients with lung carcinoma than those in healthy controls(P0 05).Conclusion The determination of plasma TXB 2,PAgT and 6-Keto-PGF 1? for lung carcinoma patients are helpful in diagnosis and treatment of lung carcinoma.

Objective To compare the success rate, the one-time success rate, the average required time and the incidence of complications of two methods in oronasal conversion of nose biliary duct in naso-biliary drainage. Methods 60 cases of patients with ENBD in the ERCP in our department from March,2008 to March, 2010 were divided into the study group and the control group by random. The patients with sleeving the gastric tube by the guidewire during oronasal conversion of nose biliary duct were considered as the study group, and the patients using the traditional method were considered as the control group. The success rate of sleeving gastric tube, the one-time success rate of grasping, the average required time and the adverse reactions of the two groups were compared. Results The success rate of the study group was 100%, and the control group was 90%, there was no statistical significance. The one-time success rate of the study group was 76.7%, higher than 46.7% of the control group. The average required time of the study group were (1.3±0.3) min, shorter than (5.1±0.7) min of the control group. The incidence of complications in the study group were 13.3%, lower than 93.3% of the control group. Conclusions To sleeve the gastric tube by the guidewire can increase the one-time success rate of grasping the gastric tube, shorten time of grasping the gastric tube and significantly reduce discomfort of patients.

Objective: To investigate the awareness of knowledge about HPV infections and the willingness to HPV vaccination among male university students in Tongzhou District, Beijing Municipality, so as to provide insights into the formulation of the HPV vaccination strategy among males. Methods: A total of 997 male university students in Tongzhou District were selected as the study subjects using a multi-stage stratified cluster random sampling method, and a self-designed questionnaire was used to investigate the awareness of HPV infections and HPV vaccine, and willingness to HPV vaccination. In addition, the factors affecting the willingness to HPV vaccination were identified. Results: A total of 935 subjects were enrolled, with a mean age of (19.08±1.38) years, and there were 570 subjects with a Beijing household registration (60.96%). Among the 313 male university students that had heard of HPV, the awareness of HPV and HPV-related diseases was 59.42%, and among the 300 male university students that had heard of HPV vaccines, the awareness of HPV vaccines was 75.33%. The willingness to HPV vaccination was 38.50%, and the willingness was high among male university students with a non-Beijing household registration ( χ2=3.971, P=0.046 ), high household annual income ( χ2trend=6.219, P=0.013 ), short distance to vaccination clinics ( χ2=19.238, P<0.001 ), having heard of HPV ( χ2=11.188, P=0.001 ), having heard of HPV vaccine ( χ2=14.548, P<0.001 ), awareness of HPV and related diseases ( χ2=16.855, P<0.001 ) and awareness of HPV vaccine ( χ2=19.299, P<0.001 ). Conclusions The awareness of HPV and HPV vaccines and the willingness to HPV vaccination are low among male university students in Tongzhou District. Improving the correct recognition of HPV and HPV vaccines and the access to vaccination services are helpful to improve the willingness to HPV vaccination among male university students.

The secretion and localization of epididymal specific proteins ESP-1, ESP-2 were systematically studied by the PAGE-western blot and ABC immunocytochemical technique in the epididymis of the rabbit. The results indicated that ESP-1 and ESP-2 represented the rabbit epididymal specific proteins of 42 kd and 20 kd, respectively. They were immunoeytochemically negative in the testis, heart, liver, spleen, lung, kidney and skeletal muscle of the rabbit as well as testis and epididymis of the rat. However, in the rabbit epididymis, except the initial segment ESP-1 and ESP-2 were started to be positive from caput segment. The ESP-1 was displyed in the supranuclear area of the principle cells, while the ESP-2 was distributed evenly in the whole cytoplasm of it. Subsequently, the most heavy positive reaction was demonstrated in the corpus epididymis and the proximal segment of cauda. In contrast of the caput, the stereocilia of principle cells and lumen sperms of the cauda epididymis were positive also. However, in the distal segment of cauda the positive reaction in cytoplasm of principle cells was gradually decreased and became disappeared completely soon, while the stereocilia of it still remained heavy positive even in that of vas deferens. The epithelium of prostate gland and seminal vesicle were negative. These results indicated that both ESP-1 and ESP-2 were secretory proteins produced mainly in the principle cells of the corpus epididymis. After releasing into the lumen, they took part of epididymal fluid and might bind on the sperm to regulate sperm maturation. The possible physiological significance of ESP-1 and ESP-2 was discussed.

Objective:To investigate the immunoregulation effect of ovalbumin immune tolerance factors (OVA ITFs).Methods:Components that were smaller than 3 kD were isolated from the splenic lymphocytes lysates of OVA tolerance mice or naive mice,respectively,named as OVA ITFs or OVA ITFs conttrol.Naive BALB/c mice were divided into 5 groups,group A,B,C,D were injected i.v.by OVA ITFs,OVA ITFs control,splenic lymphocytes from OVA tolerant mice or PBS,respectively,group E as the blank control.The percentages of CD4+CD25+ T cell subpopulation from spleens before and after adoptive transfer were measured with flow cytometer;OVA specific lymphocyte responses were assessed by MTT assay.The levels of IL-10 and TGF-?1 in the culture supernatants were tested by ELISA kits.Results:For OVA ITFs or splenic lymphocytes from OVA tolerant mice,the percentages of CD4+CD25+ T cell subpopulation from spleens after adoptive transfer were raised significantly compared with that before adoptive transfer (15.32%?1.03% and 15.35%?0.62% vs 9.97%?1.38%,P

The overuse of injection exists more than 20 years since economic reform in China. It is a persistent problem and seems becoming a new challenge in the new health reform period. This study was designed to assess the effect of national essential medicines policy (NEMP) on injection use at primary health facilities in China by investigating their prescription information. Questionnaires were designed and disseminated to collect empirical data on injection use at 120 primary health facilities in 6 provinces from January to September in 2010 and 2011. The injection use was measured as the indicator as the percentage of prescriptions with one or more injections. The results showed that the percentage of prescriptions with one or more injections was decreased from 38.91% to 36.82% (χ (2)=11.158, P=0.001) in the all survey areas during the NEMP reform. The difference in level of the injection use in 2011 was significant among the eastern, central and western regions (χ (2)=223.584, P=0.000); level of the injection use in western region was the lowest (27.73%), while that in the central region was the highest (43.10%). The level of the injection use in 2011 among different provinces was also of great difference (26.00%-58.25%, range: 32.25%). The level of the injection use in 2011 was still much higher than the standard suggested by WHO for developing countries (13.4%-24.1%). It was concluded that NEMP has improved injection use in China, but the injection abuse situation remains serious, indicating that one of the priorities to the next stage of NEMP is to promote the rational use of drugs, especially the injection use.
