The user information needs, being one of the core elements in modem library, is the basis for survival and development of modern library. In the digital and network environment, the electronic resources are increasingly becoming the main part of information resources. The Library of China Academy of Chinese Medical Sciences is the central library of traditional Chinese medicine (TCM) in China, and therefore how to use limited funds to build an optimal, most rational and sustainable development guarantee system of TCM electronic resources is its new task in the information age. This paper discussed the objective and principles of building guarantee system of TCM electronic resources, and also put forward some measures and strategies about constructing it from eight aspects.

OBJECTIVE:To study distribution and targeting of Gardenia jasminoides extract niosomes in rats. METHODS:G. jasminoides extract niosomes were prepared by modified thin film dispersion method. 30 rats were randomly divided into G. jasmin-oides extract group(57 mg/kg)and G. jasminoides extract liposome group(131 mg/kg)according to their weight. They were given relevant medicine intragastrically,once a day,for consecutive 7 days. 1 h after last administration,heart,liver,spleen,lung and kidney tissue were isolated,and HPLC method was adopted to the contents of active ingredients gardenoside in them. The targeting of G. jasminoides extract niosomes was evaluated by DTI quantitatively. RESULTS:Compared with G. jasminoides extract group, the contents of gardenoside in heart,spleen and brain tissue of rats increased significantly in G. jasminoides extract niosomes group (P<0.01),and DTI were 1.718,1.972 and 13.071;the contents of gardenoside in liver and kidney decreased significantly (P<0.01),and DTI were 0.431 and 0.467,respectively. CONCLUSIONS:G. jasminoides extract niosomes change the distribution of gardenoside in rats,showing brain targeting effect and decreasing first pass effect for liver.

Objective To investigate the changes of parathyroid hormone receptor in patients with different stages of renal disease and its possible underlying mechanisms. Methods Relatively quantitative RT/PCR method was used to detect PTH receptor mRNA expression in renal specimens obtained through biopsy or operation. Results The levels of PTH receptor mRNA were significantly decreased in all patients with chronic glomerulonephritisx moderate renal failure severe renal failure and acute renal failure, which was correlated with the extent of renal impairment. Conclusion The downregulation of renal PTH receptor occurs much earlier than the changes of renal function., plasma PTH., serum phosphate and calcium in the course of human renal disease.

Objective To compare the outcomes of TOT and TVT procedure treating female intrinsic sphincter deficiency (ISD).Methods From May 2010 to September 2015,42 stress urinary incontinence (SUI) patients whose abdominal leak point pressure was less than 60 cmH2O were enrolled in this study.Thirty-five patients were followed up.The mean age was (56.8 ±10.5) years,with a range of 30-80 years.The mean history was(10.5 ± 9.1)years,with a range of 4 months to 30 years,with 26 (74.3％) of them being postmenopausal,5 (14.3％) having a history of pelvic surgery,and no pelvic organ prolapsed or hormone replacement.All of them were randomly divided into 2 groups to undergo either TVT operation (13 cases) or TOT operation (22 cases).The baseline characteristics of the two groups including age,length of history,urodynamic parameters and scale scores showed no significant difference.The scales including urinary incontinence severity score (UISS),detrusor instability score (DIS),Quality of Life Scale Evaluation (I-QOL),lower urinary tract symptoms affect score (UDI-6) were used.The outcomes between TVT group and TOT group were compared.Result After procedure,patients in TVT group got a lower UISS score than TOT group(17.2 ± 2.2 vs.17.7 ± 3.1),and their severity of urinary incontinence improved significantly (P ＜ 0.05).Patients from TVT group got a lower DIS score than TOT group (12.6 ± 4.2 vs.14.2 ± 3.5),and their detrusor instability symptoms improved more significantly (P ＜ 0.05).Patients from TVT group got a higher I-QOL score than TOT group(17.5 ± 14.5 vs.16.1 ± 13.0),and their quality of life improved more significantly (P ＜ 0.05).Patients from TVT group got a lower UDI-6 score than TOT group (10.1 ± 3.0 vs.11.2 ± 3.4),and their lower urinary tract symptoms improved more significantly (P ＜ 0.05).Conclusion Urinary incontinence of female ISD patients were improved greater by TVT than TOT procedure.

Objective:To explore the expression of TGF-?,TGF-?1 in the tissues of pancreatic adenocarcinoma and normal pancreas,and study the changes and the relationships with the clinicopathological parameters of pancreatic adenocarcinomas.Methods:The expressions of the TGF-?,TGF-?1 were assayed in formalin-fixed paraffin embedded samples of 41 patients with pancreatic adenocarcinoma and 12 normal pancreatic tissues by means of SABC immunohistochemistry.The relationships between the expression and clinical parameters were analysied,such as ages,gender,tumor size,location,degree of differentiation and stage(UICC).Results:The positive rate of TGF-?,TGF-?1 were73.2%,63.4% respectively in pancreatic adenoeareinoma and were16.7 %,25% respectively in normal pancreatic tissues.Significant differences were found between the two groups(P

Objective To evaluate the therapeutic effects and experience of the tracheal stent implantation for the management of severe tracheal stenosis.Materials Thirteen patients with severe tracheal stenosis of various causes underwent high kilovoltage radiography and computed tomography for evaluating the site,form and extent of the stenosis including 10 at the trachea,1 at the right main bronchus and 2 at left main bronchus.The C2 catheter assisted with ultra-slipping guide wire was inserted into the trachea under fluoroscopy and then a replaced high shoring guide wire was pushed through the stenotic segment and retained the stent. Results All stents were implanted successfully with successful rate 100% together with dyspneic improvements.The mean survival time was 6.2 months for patients with malignant neoplasm.One patient with benign tracheal stenosis has been followed-up for 5 years without restenosis. Conclusions The tracheal stent implantation is an effective means for severe tracheal stenosis.

This paper firstly introduced concept,advantages,disadvantages,and application prospect of free indexing. Then the theoretical feasibility of applying free indexing in the images of TCM ancient literatures was discussed with the combination of their characteristics.In the end,the article made examples to illustrate the application of free indexing in related subjects.

Objective To investigate the effect of ketamine injected via the radicular arteries on spinal cord. Methods Twenty healthy mongrel dogs of both sexes weighing 12-18 kg were randomly divided into 2 groups ( n = 10 each): control group (group C) and ketamine group (group K). The animals were anesthetized with intravenous pentobarbital 30-35 mg/kg, fentanyl 50-100 μg and vecuronium 0.2 mg/kg and maintained with propofol ically ventilated after tracheal intubation. A catheter was inserted into T8 poster intercostal artery and advanced toward the opening of radicular artery which supplies the spinal cord. Ketamine 100 mg (in 2 ml of normal saline)was injected via the catheter in group K. Three hours after ketamine administration, the animals were sacrificed. A 1.5 cm long segment of spinal cord at the level of T8 was removed for microscopic examination and determination of the expression of NSE, S100β and Tau protein by immuno-histochemistry. Results There was no significant difference in the number of Nissl' s staining-negative neuronal cells and the expression of NSE, S100β and Tau protein in the spinal cord between the 2 groups ( P ＞ 0.05 ). Conclusion Ketamine injected via the radicular arteries does not induce spinal cord injury.

This paper is intended to figure out how to develop and maintain the traditional Chinese medical (TCM)thesaurus in the Internet Era. The history of TCM thesaurus was reviewed. The function of TCM thesaurus in searching information in internet and the impact of internet to thesauri were discussed. Suggestions on descriptor/term selection, term relations, and thesaurus maintaining were put forward.

An overview was performed on the features, structure, included terms, applications and the process of editing and compiling of traditional Chinese medical thesaurus and its relative thesaurus.
