The management of hospital medical periodicals is now facing many realistic problems such as management system of editorial department, ability of editorial team, quality of articles and outside living environment. Co-publishing periodicals with pharmaceutical enterprises, with foreign publications and innovating publishing model of periodicals have been adopted by some domestic hospitals. By studying cases of periodical management innovation, and summing up the latest domestic point of view on medical periodical management, this paper held the view that the hospital medical periodicals management should be grouped into the framework of hospital scientific research management. Basically, the hospital should focus on solving the problem of management system in priority;developing in a way of specialization, collectivization and brand-orientation;establishing of a high-level editorial team;strengthening international communication and publishing periodicals according to international rules.

Objective To evaluate the immunogenicity of a recombinant adenovirus containing the porin IB (PIB) gene and Neisseria surface protein A (NspA) gene of N.gonorrhoeae in BALB/c mice.Methods A recombinant adenovirus containing the PIB gene and NspA gene of N.gonorrhoeae (pAdEasy-1-PN) was constructed in previous studies.Thirty BALB/c mice were randomly and equally divided into 5 groups:low-,medium-and high-dose experiment group intramuscularly immunized with 104,106,and 108 50％ tissue culture infective dose (TCID50) of the recombinant adenovirus pAdEasy-1-PN,respectively,pAdEasy-1 control group immunized with 106 TCID50 of pAdEasy-1,blank control group immunized with sodium chloride physiological solution.Immunization was carried out twice at a 4-week interval.Serum samples were collected at 0,3 and 5 weeks after the first immunization,and spleens were removed at 5 weeks followed by the isolation of spleen lymphocytes.Enzyme linked immunosorbent assay (ELISA) was performed to determine the serum levels of PIB-specific and NspA-specific antibodies,methyl thiazolyl tetrazolium (MTT) assay to evaluate the proliferaton activity of spleen lymphocytes after stimulation by the recombinant PIB and NspA antigens.A slide agglutination test was used to estimate the anti-bacterial activity of murine serum.The complement-dependent bacteriolytic activity of murine serum was also evaluated.Statistical analysis was carried out by t test.Results Both humoral and cellular immune response specific to PIB and NspA were elicited by the recombinant adenovirus in mice.At 3 and 5 weeks after the immunization,significant differences were observed in the serum levels of PIB-specific (F =285.72,564.83,respectively,both P ＜ 0.01) and NspA-specific (F =521.57,542.61,respectively,both P ＜ 0.01)antibodies.Also,the proliferation index was statistically different among these groups in spleen lymphocytes stimulated with PIB and NspA (F =171.61,233.96,respectively,both P ＜ 0.01).The vaccination efficiency was positively correlated with the inoculation dose of recombinant pAdEasy-1-PN,and 108 TCID50 per dose proved to be the optimal dose for immunization.The sera from mice immunized with pAdEasy-1-PN could agglutinate N.gonorrhoeae and kill it in the presence of complement.Conclusions The recombinant adenovirus pAdEasy-1-PN containing PIB and NspA genes could induce specific humoral and cellular immune response in mice,and may be a potential vaccine against N.gonorrhoeae.

Patent competition has become one of the key issues of global competitions in economy,science and technology. In hospitals, the patent management strategy provides guidance for and impels knowledge innovation. However, hospital management is quite weak in China, which may have been caused by various reasons, such as the over enthusiasm for published paper and the technological achievement contrasted with negligence in patent application and exploitation. In the paper, countermeasures are proposed,which include the whole process management during the scientific research, setting up detail targets and standard procedures for patent management, training patent management staff, et al.

Pro-prostate-specific antigen (proPSA) is the precursor of PSA and a form of free PSA (fPSA). In recent years, a lot of studies have been done on proPSA, the roles of its related indexes in the diagnosis of prostate cancer, and the value of its clinical application. The correlated indexes of proPSA include proPSA, % pPSA, p2PSA, % p2PSA and prostate health index (PHI). They are more effective than total PSA (tPSA) and fPSA in the diagnosis of prostate cancer, especially % p2PSA and PHI, which may significantly increase our ability to detect and identify PCa and lower the rate of unnecessary biopsies. This article presents an overview on the advances in the studies of proPSA and the application of its related indexes in the diagnosis of prostate cancer.

ObjectiveTo evaluate the attachment type,the level of alexitymia and the defense style of depression patients and their relativity.Methods 32 depression patients were assessed with the adult attachment scale (AAS-1996 Revised Edition),toronto alexithymia scale (TAS) and defense style questionnaire( DSQ),and 80 healthy people were involved as controls.Results The depression patients showed significantly different attachment type from the control group( x2 =47.6,P ＜ 0.01 ).Compare with the control group,the depression patients showed higher scores in immature defense style( (5.47 ± 1.13 ) vs (3.79 ± 1.09 ) ) and neurotic defense style( (4.93 ±0.56) vs (4.20 ± 1.00),(P＜0.01) ).Compared with controls,the depression patients showed higher scores in TAS total score( (76.88 ± 8.94) vs (65.70 ± 7.98 ) ) factor Ⅰ ( ( 3.34 ± 0.77 ) vs ( 2.41 ±0.78)) and factor Ⅱ ((3.64 ±0.51) vs (2.65 ±0.55),P＜0.01),and lower scores in factor Ⅲ((2.51 ±0.78) vs (3.14 ± 1.03 ),P ＜ 0.01 ).The depression patients' adult attachment was significantly correlative with their scores of alexithymia.The depression patients' adult attachment was also significantly correlative with their scores of defense style.ConclusionThe attachment of depression patients may lead to depression via their defense style.Depression leads to alexitymia.Depression patients with different features of attachment show different level of alexitymia.

BACKGROUND: Rhodiola rosco L acts on anti-aging,anti-fatigue and improving immunity in human body and improves angina pectoris.OBJECTIVE: To study the effect of rhodiola root on heart hemodynamics and myocardial contractility and probe into its mechanism.DESIGN: Observational and controlled based on the experimental animals.SETTING: Department of physiology in a medical university.MATERIALS: The experiment was performed in Laboratory of Cardiac Vessels of Department of Physiology of Guangxi Medical University,from January to April 2001.Thirty New Zealand white rabbits of either sex,weighted varied from 1.9 to 2.3 kg,were randomized into two groups,named as the control(physiological saline 4 mL/kg) and rhodiola sacra SH Fu (nuodikang) group(0.5 g/4 mL · kg-1),15 rabbits in each group. A hundred common wild frogs were employed,weighted varied from 120 to 160 g,randomized into 4 groups, named as the control group of physiological saline,nuodikang of small dosage group(blood concentration 209 mg/L),nuodikang of moderate dosage group(blood concentration 418 mg/L) and nuodikang of large dosage group(blood concentration 627 mg/L),25 frogs in each group.METHODS: ms2000 multiple medium biological signal analysis system was applied,by Straub method,frog heart perfusion specimen in vitro was prepared and the cardiac activity was assayed. The relevant indexes of ventricle activity in rabbits were determined with hemodynamics.MAIN OUTCOME MEASURES: Comparison of hemodynamics changes in rabbits of two groups and the comparison of effects of nuodikang at various dosages on frog heart work in vitro.RESULTS: Myocardial contractility in every nuodikang group was strengthened remarkably compared with the control(F = 8.939, P<0.01 ), the myocardial contractility in nuodikang groups at the dosages of 209 mg/L,418 mg/L and 627 mg/L was in the tendency of increasing,strengthened by 52. 3%,70. 1% and 86.4% respectively. But the significant difference was not apparent in the comparison among experimental groups(P>0.05). The significant difference in frog heart rates among groups was not apparent(P>0.05). Concerning to hemodynamics in rabbits,in nuodikang groups,the maximum increasing rate of pressure in the left ventricle was increased by 22.1% (F = 6.259,P<0.05),the mean pressure of artery was decreased by 8.2% (F = 5.688, P<0.05) . The significant difference in other indexes was not apparent in the comparison between the control and nuodikang groups.CONCLUSION: Nuodikang strengthens myocardial contractility and speeds up myocardial contraction, but does not present remarkable influence on myocardial dilation; simultaneously it reduces the mean pressure of artery.
