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.

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.

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.

Currently,research and practice in the of hospital management in China are at low level.This paper agrees that the innovation of hospital research management should be based on scientific knowledge management,knowledge communities is a core component of knowledge management implementation in hospitals.This paper descripts the method that how to buide the knowledge community,for example,the types of knowledge community,hospital knowledge system,and the job title based knowledge map and process-oriented knowledge map.

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.

Objective:To investigate the value of ultrasonography in the diagnosis of cystic renal cell carcinoma(CRCC).Methods:To review and analyze 32 cases confirmed by histological examination with the complete data and to sum up their characteristic features of ultrasonographic appearance,and then compared with the results of CT.Results:The sensitivity of ultrasonography in the diagnosis of cystic renal cell carcinoma was 75.00%(24/32),CT was 87.50%(28/32),therefore there was no obvious statistical difference between them.Conclusion:Color Doppler ultrasonography has diagnostic value in cystic renal cell carcinoma.

Clinical work is the core of a hospital. The level of the clinical work and scientific research are the major indexes for the evaluation of a hospital or a clinician. However, there seems contradiction between the clinical work and scientific research. For hospital administration and clinicians, it is important to adopt clinical work as the center, and conduct research around the clinical practice, which will facilitate the transition from the scientific research to clinical application. Eventually the clinical work will improve and medical science will develop.

OBJECTIVE:To observe analgesic effect and safety of ketorolac tromethamine combined with butorphanol tartrate in the treatment of acute pain after fracture surgery. METHODS:76 acute pain patients after fracture surgery were selected and ran-domly divided into control group and observation group,with 38 cases in each group. Control group was given Ketorolac trometh-amine injection 30 mg,ivgtt,and then 2 ml/h,0.5 mg/kg,ivgtt;observation group was additionally given butorphanol tartrate 10 mg,ivgtt,on the basis of control group. Pain degree was evaluated with VAS before and 10 min,1,2,4 and 6 h after treatment, and the occurrence of ADR was observed in 2 groups. RESULTS:10 min,1,2,4 and 6 h after treatment,VAS score of 2 groups were significantly lower than before,with statistical significance(P<0.05);6 h after treatment,VAS score of observation group was significantly higher than that of control group,with statistical significance (P<0.05);there was no statistical significance in VAS score between 2 groups 10 min,1,2 and 4 h after treatment (P>0.05). The incidence of ADR in observation group (5.26%)was significantly lower than in control group(21.05%),with statistical significance(P<0.05). CONCLUSIONS:Com-pared with ketorolac tromethamine alone,ketorolac tromethamine combined with butorphanol tartrate shows shorter analgesia dura-tion,similar therapeutic efficacy,and lower incidence of ADR.

Objective To investigate serum nesfatin-1 levels in type 2 diabetes (T2DM)patients with or without nonalcohol-ic fatty liver(NAFLD).Methods The hight,weight,serum GLU,lipid profiles,INS,HbA1c,ALT,nesfatin-1 levels were measured in 21 1 T2DM patients[98 without NAFLD(TD2M without NAFLD group)and 1 13 with NAFLD(TD2M with NAFLD group)] and 75 normal subjects(NGT group).BMI、HOMA-IR were also calculated.Results The serum nesfatin-1 level was significantly higher in T2DM group than those in NGT group(P <0.05),and T2DM with NAFLD group had higher nesfatin-1 level than T2DM without NAFLD group (P < 0.05 ).There was a close relation between nefastin-1 of T2DM group and course of disease (r=-0.447,P <0.05).NAFLD existed a significant correlation with BMI、TG and nesfatin-1 (P <0.05).Conclusion nesfatin-1 may partially contribute to the pathogenesis of T2DM and NAFLD.
