79 cases (180 amputated fingers) underwent gradual distraction through phanlanges. The bone elongation obtained varied from 1 to 3.2 cm, with an average of 2.2 cm. Finger stumps were examined by measurement of 2 point discrimination (2PD) and sensative nerve conduction velocity as well as SO, both before and post lengthening. We confirmed that it was safe to distract the finger stump at a daily rate of 1 mm. Several fingers can be lengthened simultaneously using our device. The adjacent joint was also stretched other than compressed. Therefore, the lateral accessory ligament contraction and joint crush injury were avoided. The long-term length increase was maintained by subperiosteal osteotomy. Gradual finger lengthening is a simple, safe and effective method.

Objective To establish the diagnosis of am niotic fluid em bolismwith blood sam ples by liq-uid-based cytology technique and to study the validity of m ethod. Methods The blood sam ples were collected from patients who suffered from am niotic fluid em bolism. The com ponents of am niotic fluid in blood samples were examined with blood smear by two direct smear methods(supernatant smear, sedi-ment smear) and two liquid-based cytology methods(autom atic smear, manual smear). The positive de-tection rate of each m ethod was calculated. Results The positive detection rates of two liquid-based cy-tology methods(84.6% and 92.3%, respectively) were m uch higher than those of two direct methods(53.8% and 61.5%, respectively). Conclusion The liquid-based cytology technique could im prove the positive detection rate of am niotic fluid em bolism.

Objective To establish an HPLC method for determination of gastrodigenin concentration in brain tissue of mice and investigate its pharmacokinetics after intragastric administration of gastrodin.Methods The brain homogenate was extracted with acetoacetate and analyzed by HPLC method.The separation was performed on a Diamonsil C18 column(250 mm ? 4.6 mm,5 ?m) under the following chromatographic conditions: mobile phase,acetonitrile-water(10.5∶89.5);column temperature,25 ℃;flow rate,1.0 mL/min;detection wavelength,221 nm;and sampling amount,20 ?L.Results The calibration curve showed good linearity within the concentration range of 50-1 616 ng/mL(r= 0.999 6).The relative recoveries were 93.8%-95.1%,and the RSDs of the intra-and inter-day precision were less than 10%.The concentration-time profile of gastrodigenin in brain tissue of mice showed double peaks(tmax1=15 min,tmax2=90 min).The AUC was 52 822.5 ng?min/g,and t1/2(ke) was 54.8 min.Conclusion The analytical method established for assay of gastrodigenin in brain tissue of mice is sensitive and accurate.The result indicates that gastrodin could rapidly distribute to the brain,be metabolized into gastrodigenin,and be eliminated after oral administration.

Remaining organic and functional damage of ischemia cardio-cerebrovascular disease is always a main trouble puzzling the clinicians. After the discovery of endothelial progenitor cells (EPCs), researchers realize that postnatal angiogenesis is an important biological process, which play a key role to repair the ischemia tissue and improve the function. So a new concept which names therapeutic angiogenesis supply a new treament way for the ischemia cardio-cerebrovascular disease. Traditional Chinese medicine (TCM) has accumulated rich experience on treating the ischemia disease, studies found that many Chinese medicine prescriptions and effective ingredients can increase the therapeutic angiogenesis, howerer the mechanisms were not the same, they mainly manifest in regular the secretion of angiogenic factors, increase the proliferation and differentiation etc. In this paper, we review recent studies, summary the Chinese medicine prescriptions and effective ingredients which can increase the therapeutic angiogenesis, and analyze the differernt pathway. We view to provide reference for the later researchers.

Objective To explore application effect of evidence-based nursing in operation of rupture of liver and apleen. Methods 108 patients with rupture of liver and spleen received evidence-based nursing during perioperative period, that is, to determinate nursing problems needed to prove, retrieve and analyze related articles, make the best nursing mode and prevent complications. Results Complications appeared in 15 patients, intra-abdominal hemorrhage in 4 patients, infection in 7 patients and splenic fever in 4 patients. All were corrected in time, and no case showed thrombosis and organ failure. Conclusions EBN can prevent post-operative complications for patients with rapture of liver and spleen and improve nursing quality.

In order to study the pathogenesis of HPVl1 and seek for a therapeutic approach of the disease caused by HPV1l. The HPVl1/E2 644bp was amplified by PCR with HPVll plasmid DNA. pGEM-T Easy was used as vector and a clone pTV-644 was obtained.The inserted DNA sequencing was carried out after selecting and identification. According to the hammerhead structure described by Symon's, the possible secondery cleavage sites on HPVll/E2 mRNA were analyzed and the secondery structure of substrate was predicted by computer and ribozyme, excluding analogous sequence of substrate combined with ribozyme were found in the mRNA.The hammerhead ribozyme of RZ2777 against HPV1l/E2 mRNA was seleted to carry out cleavage reaction in vitro. Results of the experiment showed that 644bp substrate derived from HPVll/E2 can be cleavaed site-specifically by ribozyme in vitro. The cleavage activity showed over 85% by choosing the optimun reaction condition, which was not affected by two cis-ribozymes on both 3′-and 5′-ends released by self cleavage,but two flan-king sequences of target RNA influenced the cleavage activity. Results demonstrated that the ribozyme will become a highly effective and specific therapy against HPVll infection.

Objective To observe the resection of the scapholunate interosseous ligament (SLIL)and its subregions on the three-dimensional(3-D)movement of the scaphoid and lunate so as to discuss the role of SLIL in the 3D flexion-extension motion of the scaphoid and lunate.Methods Twelve upper extremities(six left extremities and six right extremities)from adult cadaver were used in this study and divided into five groups:normal group,proximal subregion resection group,proximal subregion plus dorsal subregion resection group,proximal subregion plus palmar subregion resection group and whole SLIL resection group.The 3-D laser scan and reconstruction technique were used for meusure ment of the 3-D flexion-extension motion of the scaphoid and lunate.Results In the normal group,the scaphoid and lunate flexed and the radial deviated at the same direction during wrist flexion-extension motion.At the same time,there was minimal scaphoid and lunate pronation-supination during wrist flexionextension.After resection of the proximal and palmar(or dorsal)subregions of the SLIL,some different movements were found compared with the normal specimen.Whole SLIL resection resulted in increase of the flexion motion of the scaphoid but decrease of the palmar flexion of the lunate.Conclusions 3-D laser scanning and image reconstruction techniques can accurately measure the 3D motion of the scaphoid and lunate.Partial or whole resection of SLIL may exert significant effect on the flexion-extension motion of the scaphoid and lunate.However,the proximal subregion of SLIL has no prominent effect on the motion of the scaphoid and lunate.

Objective To investigate the effects of mycoplasma pneumoniae(MP)infection on the exhaled nitric oxide level and lung function in asthmatic children,analyze the correlation between exhaled nitric oxide level and lung function and to provide reference for the treatment and monitoring of asthmatic children.Methods Sixty-eight children aged from 5 to 13 years old with mild or moderate asthma during June 2011 to January 2013 were collected.MP-IgG antibody,MP-IgM antibody,MP-DNA,total serum IgE,FeNO measurement and spirometry were examined on the next day morning.They were divided into two groups according to the pathogen:ashtma with MP group and ashtma without MP group.Then the levels of nitric oxide level and lung function indicators between the two groups were analyzed.Results The FeNO level in ashtma with MP group was significantly higher(P<0.05).There were no differences between two groups in lung function parameters such as FVC,FEV1,FEV1 / Vcmax,MEF25 and MEF50(P>0.05),but differnces were found in MEF75 and PEF(P<0.05).No correlation was found between FeNO levels and lung function parameters(FVC,FEV1,FEV1/Vcmax,MEF50,MEF25,MEF75 and PEF).Conclusion In asthma children with MP infection,the FeNO level was significantly increased and no correlation was found between FeNO levels and lung function.
