OBJECTIVE To know the gene type of Staphylococcus aureus which caused the respiratory tract infection of patients after transplantation in our hospital,and to explore the epidemiology,preventing measure and nursing strategy of the lung infection by S.aureus among them.METHODS Using random amplified polymorphic DNA(RAPD) to analyze the gene type fingerprint of the 20 S.aureus strains originated from the respiratory tract of patients after transplantation,and using cefoxitin paper strip method to detect the mecA gene of the S.aureus.RESULTS Twenty S.aureus strains were divided into 8 gene types,and among them,the detectable rate of gene types Ⅰ,Ⅱ,and Ⅲ was 40.0%,15.0%,and 15.0%,respectively.The positive rate of mecA gene reached to 80.0%.CONCLUSIONS The S.aureus originated from respiratory tracts of the patients after transplantation is mainly of gene type Ⅰ.And the positive rate of mecA gene is very high.So the management of hands washing,sterilization and isolation of medical and nursing staffs should be strengthened,and effective method should be took to prevent the propagation of mecA positive S.aureus among the patients after transplantation.

Objective To explore the significance of established Tp0259-PCR in diagnosing primary syphilis.To provide basis for establishing new PCR diagnosis method of Treponema pallidum.Methods Specific primers were designed by the gene sequences of Tp0259 which was obtained from Genbank.Tp0259-PCR was established under the optimization reaction condition.Using the new construction of amplification method to detect the common pathogenic microorganism in urinary and reproductive tract infec-tion.42 clinical secretion specimens suspected primary syphilis were tested by Tp0259-PCR.Serum specimens from the same pa-tients were tested by TPPA.Results Only specific amplicons could be found in amplifying the Treponema pallidum by Tp0259-PCR.The detection rate was 73.8% using Tp0259-PCR which was apparently higher than 57.1% using TPPA(P <0.05 ).The specificity of the established method was 100% comparing with TPPA.Conclusion The established method of Tp0259-PCR has high sensibility and specificity.This method might be better than serological method in diagnosis of primary syphilis.but its clinical diagnosis value need to be repeatedly verified by more clinical specimens.

0.05). After operation about 50% cases (11/22) improved the menstrual dysfunction, and most cases avoid doing operation again in short period. Conclusion While cases chosen properly and adequate operative preparation, it is feasible and valuable to carry out cesarean section and myomectomy at the same time.

Objective To study the effects of Leptin on the expression of CD86 and HLA-DR in human monocytes.Methods The expression of CD86 and HLA-DR in THP-1 Cells and human primary monocytes were detected by flow cytometry.Results Expression of CD86 and HLA-DR in THP-1 cells was significantly increased after treatment with high-dose Leptin ( CD86Untreated group:8.78 ± 1.66,CD86leptin10:50.76 ± 4.29,CD86leptin100:95.20 ± 4.90; HLAUntreated group:20.75 ± 2.12,HLAleptin10:102.14 ± 5.75,HLAleptin100:104.32 ± 4.75;).The similar results were observed in human primary monocytes ( CD86Untreated group:17.91 ± 1.78,CD86leptin100:48.80 ± 3.60; HLAUntreated group:34.10 ± 2.76,HLAleptin100:88.86 ± 3.53).Conclusions By up-regulating CD86 and HLA-DR expression,Leptin might enhance the ability to present antigen in THP - 1 cells and human monocytes.

Objective: To study the curative effects of Rupixiao Grains on mammary hyperplasia rats and provide the bisis for the wider use. Methods: The model of mammary hyperplasia were established with estrogen and progestogen, the changes of nipple appearance and pathological tissue of mammary gland on morphologic change were observed. The E2, P and PRL of serum were determined. Results: The treatment groups of high and middle dose of Rupixiao Grains can siginifi cantly reduce the diameter and height of nipple in rat mammary gland hyperplasia models(P

AIM: To investigate the role of the nucleus tractus solitarius (NTS) in the regulation of paraventricular nucleus (PVN) AVP-ergic neurons on gastric ischemia- reperfusion injury (GI-RI). METHODS: Male SD rats were used in experiments. The celiac artery were clamped for 30 min and reperfused 1 h by removal of the clamp to obtain the ischemia-reperfusion state. The mechanism was analysed with nucleus electrical stimulation, electrolytic lesion and nucleus microinjection technique. RESULTS: Microinjection of arginine-vasopressin (AVP) into PVN obviously attenuated the GI-RI and dose-dependent effects were observed ( r= -0.477, P

AIM: To determine the effect of electrical stimulation of lateral hypothalamic area(LHA) on gastric ischemia-reperfusion injury(GI-RI) in rats and to analyse its possible neuroregulatory mechanisms. METHODS: The methods of electrical stimulation(ES), chemical stimulation, electrolytic lesion(EL) and denervation were used to investigate the effect of LHA ES on gastric mucosal injury in rats subjected to 30 min gastric ischemia followed by 60 min reperfusion and to analyse the role of dorsal vagal complex(DVC), vagus and sympathetic nerve in this effect. RESULTS: ①Electrical stimulation of LHA and microinjection of L-glutamic acid into LHA obviously aggravated GI-RI; ②Electrolytic lesion of the LHA attenuated the GI-RI;③DVC lesion eliminated the effect of electrical stimulation of LHA on GI-RI; ④Vagotomy or sympathectomy eliminated the effect of electrical stimulation of LHA on GI-RI too.CONCLUSION: These results indicate that the LHA is a specific area in the CNS for exerting aggravative effects on the GI-RI; the DVC, vagus and sympathetic nerve may be involved in regulatory effects of LHA on GI-RI.

Objective To construct and implement the nursing quality information feedback system based on QUACERS model and control theory, and discuss its application effect and the problems that should be paid attention to and to provide operational cases and practical basis for nursing quality management. Methods Through literature review and expert consultation, the framework and content of nursing quality information feedback system were set up and implemented. The changes of the nursing quality and the repeated occurrence of nursing problems were evaluated before (2013) and after (2015) the implementation of this project. And in December 2015, a self-made questionnaire was conducted among the nurses in the hospital to evaluate the importance of the feedback and it′s effect of improving the nursing quality. And evaluate the timeliness and effectiveness of different feedback forms. Results 1 120 and 1 136 nurses were followed-up in 2013 and 2015 respectively. The scores of human resource management, clinical nursing service and nursing safety management were higher than before, and the repeated occurrence of nursing problems was lower than before. A total of 450 questionnaires were distributed, 438 copies were collected, the effective recovery rate was 97.33%. Ratings for the importance of each item was from 3.37 to 4.57. Ratings for the effect of improving the quality of care was 3.79 to 4.39. The percentage of quality information received by nurses was more than 95%, and the average score of feedback timeliness was 4.29 to 4.53. Conclusions Quality information feedback system based on QUACERS model can cover multiple dimensions of quality management, and it was conducive to obtaining comprehensive information;Combined with multiple feedback forms can improve the effect of information feedback.
