Along with the quickly popularization of Internet, the literature resource sharing mode in library has been changed. The paper introduces the current development of it, including interlibrary loan, document delivery, IC card service, proposes shortcomings and ideas for the further development of literature resource sharing.

Objective To observe the curative effect of treating CHD angina pectoris with the therapy of clearing away heat and detoxification. Methods Sixty patients with angina pectoris were randomly recurited into two groups, a trial group and a control group. The trial group was treated by Chinese medicine which has the efficacy of clearing away heat and detoxification (Qingre-Jiedu decoction) and conventional therapy of Isosorbide Mononitrate tablets as same as the control group. The period of treatment was 4 weeks. Compare the curative effect and the change of ECG between the two groups after the treatment. Results After the treatment,the curative effect and the change of ECG of the trial group were both better than the control group with significant difference (P< 0.05). Conclusion It was better to treat coronary heart disease with the management of clearing away heat and detoxification and western medicine than that with western medicine only.

0.05). - 40 mV activated threshold potential and - 30 mV peak potential for control group respectively droppedto - 60 mV and - 40 mV after irradiating 7 min. The half-activation voltage and the slope factor of the activationcurves of Na+ channel were also changed by the laser's exposure. The former changed from (- 42.091 ?1.537) mVto (54.971 ?1.846) mV (n= 8, P

[Objective]To evaluate the clinical effect of the plastic splint on treatment of Colles fracture.[Method]A total of 105 patients with Colles fracture were collected between September 2002 and August 2008.All patients were perfromed using the plastic splint afrer diaplasis.According to Gartland and Werley scoring syste,the function of wrist was evaluated after 3 months.[Result]There are only 2 cases losing during treatment,103 cases were finished.The average excellent to good case was 90.3%,including 80 cases of being excellent,13 of being good,7 of being fair and 3 of being poor.[Conclusion]The plastic splint is exactly effective to treatment Colles fracture,especially,it could effectively relieve swelling and improve the contour of the wrists.Theses all rely on reasonable biomechanics design.

?Objective: To design a new implant distraction apparatus.Methods:The implant distraction apparatus was designed on the bases of Ilizarov theory,made of pure titanium TA 2 and prepared as a set including distractor and accessories.Inferior edge of a dog's mandible was prepared for implantation. After horizontal osteotomy, two implant distraction devices were applied.Results:The transport bone segment was vertically augmented 3 5 mm successfully,and the ditraction apparatus was stable.Conclusion: The implant distraction device is functional in distraction osteogenesis.

Objective To explore the role of focus intervention mode in improving the self-efficacy and subjective well-being of newly-contracted nurses. Methods A total of 100 nurses selected as the survey subjects by means of convenient sampling method, were numbered consecutively and divided into observation group and control group by random digit number table. The observation group was intervened with conventional mental consultation and the observation group with the WeChat-based focus intervention mode, which included the use of past-oriented questions and answers for understanding their strength and sources, future-oriented presuppositions and miracle-oriented questions for their thinking of resolutions to future problems. The two groups were compared in terms of general self-efficacy and well-being by the general self-efficacy scale (GSES) and the overall well-being scale (GWB). Results Before intervention , the total scores on GSES and GWB of the observation groups were insignificantly higher than those of the control group (P > 0.05). After intervention, the scores of observation group were significantly higher than those in the control group (P < 0.01). Conclusion The We-Chat-based focus intervention mode can effectively improve the self-efficacy and subjective well-being of newly-contracted nurses.

Sleep-wake disturbance is not only a risk factor for stroke,but also one of the serious complications of stroke.The main clinical manifestations of post-stroke sleep-wake disturbance are insomnia,arousal disorders,sleep-related movement disorders and parasomnias.Its mechanism is mainly associated with the sleep-wake center after stroke injury.

Objective To study the indication,method and value of choledochal exploration through cystic duct.Methods The cystic duct was cut 0.5～1 cm from choledochus and its edge was raised with a forceps and a bakes dilator was inserted to probe the bill duct.If the dilator can not pass the choledochus,palpation around the point of dilator would help to distinguish the stone tumor or narrow.Results In 51 patients with cholecystitis and cholelithiasis,36 were explorated,of which 6 had the explorative indications,4 were postive(66.6%);in 30 without the indications,3 were positive(10%).The total positvity was 19.4%.Conclusions This method is less traumatic,convenient and able to find choledochal disease accurately.The exploration would be done if the cystic duct is over 0.3 cm in diameter.

OBJECTIVE:To determinate the serum concentration of methotrexate by HPLC. METHODS:The samples were separated on a Waters C18 column at a column temperature of 30 ℃. The mobile phase consisted of acetonitrile-phosphate buffer(pH 7.2,12∶88) at a flow rate of 1.0 mL?min-1. The detection wavelength was set at 303 nm. RESULTS:The linear range of methotrexate was 0.5～80 ?g?mL-1(r=0.999 4). The methodological recovery rates were all above 90%; the intraday RSD was 3.03 %～3.52 % and the inter-day RSD was 2.57%～4.05%. CONCLUSION:The method is proved to be simple,rapid,accurate and sensitive,and it is suitable for the determination of serum concentration and pharmacokinetic study of methotrexate.

Objective To evaluate economic benefits and clinical effects of internal fixation treatment of severe rib fracture so as to provide objective basis for improving medical treatment for rib fracture.Methods A retrospective review was made on clinical data of 50 patients with severe rib fracture hospitalized from January 2009 to April 2014.With varied treatment modalities,the patients were assigned to operative group (n =13) and non-operative group (n =37).Variables were recorded including length of stay,total hospital charges,length of ventilatory support,off-bed time,duration of antibiotic use and incidence of complications and used to perform cost-efficiency analysis.Results Between operative and non-operative groups,length of hospital stay was (25.9 ± 8.2) days vs (35.4 ± 7.0) days,total hospital charges were (121 676.2 ± 10 991.1) yuan vs (148 724.5 ± 21 254.3) yuan,length of ventilatory support was (7.9 ± 2.8) days vs (14.1 ± 3.3) days,off-bed time was (14.3 ± 4.9) days vs (26.1 ± 6.5) days,duration of antibiotic use was (12.4 ± 3.3) days vs (21.2 ± 6.2) days and complications occurred in 2 cases vs 13 cases respectively.The findings were length of ventilatory support,off-bed time and duration of antibiotic use differed significantly between the two groups (P ＜ 0.05).Cost-effectiveness ratios based on subjective and objective measures were superior in operative group (1 962.52 and 3 925.03) over those in non-operative group (1 931.48 and 3 718.10),suggesting operative treatment could yield higher economic returns.Conclusion Internal fixation can accelerate bone healing in patients with severer rib fracture and cut down medical expense,which should be promoted in medical treatment.
