AIM　The purpose is to investigate the Anti-inflammatory mechanism of Biota orientalis. METHODS　Using rat leukocytes and rabbit platelets as experimental material the biosynthesis of leukotriene, 12-hydroxyheptadecatrienoic acid(12-HHT) and 12-hydroxyeicosatetraenoic acid(12-HETE) in the cells was determined with HPLC. RESULTS　Biota orientalis was shown to inhibit the biosynthesis of leukotriene B4(LTB4) and 5-hydroxyeicosatetraenoic acid(5-HETE) with IC50 of 0.40 and 0.41　mg/ml crude herb, respectively. It was also displayed to inhibit biosynthesis of 12-HHT in the platelets. CONCLUSION　Biota orientalis leaves contain anti-inflammatory components and the anti-inflammatory mechanism was related with inhibiting metabolism of arachidonic acid.

AIM To investigate the anti-inflammatory eff ec t of total flavonoids isolated from Platychadus orientalis and its mechanism . METHODS The inflammatory models in mice and swelling of rats hind paws were induced by dimethylbenzene and carrageenan respectivel y. The biosynthesis of leukotriene and ?-glucuronidase release in the cells we re measured by HPLC and fluorescence spectrophotometer respectively. RES ULTS Total flavonoids isolated from Platychadus orientalis remarkably inhibited the ear edema induced by dimethylbenzene in mice at the dose of 12.5 ～50.0 mg?kg -1 and the swelling of rats hind paws induced by carrageenan at the dose of 25.0～50.0 mg?kg -1 . Total flavonoids at final concentrati on of 5.0～125.0 mg?L -1 inhibited 5-HETE and LTB 4 synthesis by 30.5%～ 87.3% and 27.8%～84.3% respectively. In comparision with controls, Total flavono ids at final concentration of 5.0～45.0 mg?L -1 inhibited ?-glucuronidas e release by 13.4%～32.2%. CONCLUSION Total flavonoids isolated f rom Platychadus orientalis has an anti-inflammatory effect which may be rel ated to inhibiting 5-HETE and LTB 4 production and ?-glucuronidase release.

Objective To evaluate the values of visual inspection with acetic acid( VIA) and human papillomavirus( HPV) and thinprep cytology test( TCT) in the screening of cervical cancer.Methods VIA,HPV test and TCT in 946 women was conducted.Cervical biopsy or endocenical curettage( ECC) was performed in VIA positive women or HPV positive women or TCT positive women. The pathologic outcome was as the gold standard,and the out come more and equal to cervical intraepithelial neoplasia( CIN) Ⅱ were identified as positive.Results There was no significant difference among three groups in sensitivity rate( 73.l％,96.2,88.5％ ) and negative predictive value ( 99. 1％ ,99.9％ ,99.7％ ) ( all P ＞ 0.05 ).The specificity rate (97.5％ ) and positive predictive value ( 50.O％ ) of TCT was better than those of HPV ( 93.5％,29.4％ ),and HPV was better than those of VIA( 87.0％,13.7％ ),and the difference had statistifical significance among three groups ( x2 =71.34,26.00,22.17,8.28,all P ＜ 0.05 ).Conclusion Although the rate of missed diagnosis and misdiagnosis rate was higher than that of HPV and TCT,but VIA seems to be appropriate methods in the screening of cervical cancer owing to its low price.

Objective To explore the effect of intravenous infusion flow rebuilt on the patients’safety and nursing quality in intravenous infusion center.Methods Risk safety factors about intravenous infusion process in intravenous infusion center were analyzed and the work flow were rebuilt and optimized?The satisfaction rate,the reception time and the disinfection time for tourniquets were compared before and after work flow rebuilt.Results After work flow rebuilt,the satisfaction rate raised from 92?5%to 94?5%?There were significant differences among the reception time and the disinfection time for tourniquets before and after work flow rebuilt (all P<0?05)?After work flow rebuilt,both the reception time and the time for dealing with tourniquets are shorter than before. Conclusions The rebuilt work flow can make nurses work efficiently and enhance the patients’nursing quality?

Objective To study TCM pattem rules of primary hyperlipemia and its relation with sex,age,body mass index(BMI).Methods A total of 1 20 patients with primary hyperlipemia were divided into 5 groups by TCM syndrome differentiation:56 patients in a group of the turbid-phlegm stagnation syndrome,35 patients in a group of yang deficiency of spleen and kidney syndrome,13 patients in a group of yin deficiency of liver and kidney,7 patients in a group of hyperactivity of yang due to yin deficiency group,and 9 patients in a group of qi stagnation and blood stasis syndrome.Statistic analysis was made on factors that may affect these syndromes,and the correlations were discussed.Results Different age showed a closer relation to the onset of primary hyperlipemia than other factors(P＜0.01):sex,clinical classification,and accompanied diseases had no relation with the five-type syndromes(P＜0.01).Conclusion TCM syndromes had a certain relation with the age of patients with primary hyperlipemia.

Objective To explore the effect of multiple-formed nursing teaching ward-round.Methods Trainings and practices about muhiple-formed nursing teaching ward-round were executed to clinical instruction teachers.Results 95.9%of nursing students were satisfied with the quality of nursing teaching ward-round.After training ang practices,the evaluation to the nursing teaching ward-round and the scores of theoretic and operation examination of nursing students raised significantly(P＜0.05).Conclusions The trainings and practices improve the teachers' ability of utilizing multiple-formed nursing teaching ward-round,which not only enhance the students' study initiative,but also improve the query of nursing teaching teaching ward-round.

Objective To analyze the clinical characteristics and the endocrine changes in children with craniopharyngioma,and to improve the pediatrician understanding of the disease.Methods The study subjects consisted of 14 children with craniopharyngioma admitted to the Department of Endocrinology,Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2004 to Dec.2012.All the patients were followed up to analyze the clinical symptoms improvement,endocrine test results and medication,et al.Results The main clinical manifestations were headache (7/14 cases,50.0％),growth retardation(4/14 cases,28.6％),vomiting (4/14 cases,28.6％),polydipsia/ polyuria (3/14 cases,21.4％) and vision diminution (3/14 cases,21.4％).Three patients didn' t undergo the surgery,and 3 cases with diabetes insipidus and 2 cases with growth hormone deficiency,and 1 case with central hypothyroidism by laboratory test.The rest 11 children received surgery and all patients had changes in endocrine after it.Five cases got polydipsia and polyuria,other 5 cases had electrolyte disturbances,and 2 cases had epilepsy.Nine patients were followed up,and the follow-up duration ranged from 5 months to 10 years [(3.29 ± 3.52) years] after surgery.Seven patients got better and 2 patients got worse.Conclusions For clinical symptoms of increased intracranial pressure,changes in endocrine,the vision and visual field,the possibility of craniopharyngioma should be taken into account.Surgery is the main treatment,but it can lead to the damage of hypothalamus and pituitary gland.Changes in endocrine,electrolyte disturbances and epilepsy are the common complications.According to the level of endocrine,longterm hormone replacement therapy for some postoperative patients should be continued.

Sudden sensorineural hearing loss (SSHL),which is a common and frequently encountered disease,is considered to be a medical emergency in otolaryngology.The prevalence of SSHL is increasing in China.The pathogenesis of SSHL is not clear yet.Microcirculatory disorder of inner ear is considered as one of the most important causes of SSHL.In recent years,several reports have found the levels of serum lipids were changed in patients affected by SSHL.The relationship between SSHL and serum lipids was reviewed to provide new ideas for the diagnosis and treatment of SSHL.
