Rhynchophylla is a Chinese herb commonly used in clinical practice. It's also the primary herb of some famous Chinese herbal compound such as Tianma Gouteng decoction, and Lingyang Gouteng decoction. According the record from many previous materia medica literatures, rhynchophylla should be added later during decoction. Pharmaceutical research showed that rhynchophylla alkaloids were not stable. Which has resulted in many problems in the research and its application. For example, there was not a quantitative determination method in "Chinese Pharmacopoeia" of past and present versions, which seriously impacted its quality control and product application. Firstly, records from previous materia medica literatures and "Chinese Pharmacopoeia" were systematically sorted based on the chemical stability of rhynchophylla. Secondly, pharmaceutical research including chemical compositions and their stability, pharmacological effects, extraction process and quality analysis, was reviewed after reference of literatures published at home and abroad in recent decades. Positive reference and evidence for further research and development of rhynchophylla will be provided in the article.

Objective To evaluate the functional outcomes and complications of patients with bone tumors who were treated with the excision-alcoholization-replantation (EAR) method. Methods From August 1965 to August 2003, 191 patients treated with the EAR method who had suitable follow-up were evaluated in our department, including 102 males and 89 females with an average age of 20 years (range, 10-62). On the basis of Enneking tumor staging, 136 patients were identified II B stage, 25 I B stage, and 30 invasive benign tumors and tumor-like lesion. The length of the resected part ranged from 5 cm to 26 cm, with marginal resection in 30 cases, wide resection in 116. The oncological parameters that were evaluated included survival of the patients, local recurrence, and metastasis. Complications included non-union, infection, and fracture of the grafts. Mankin evaluation system was used to assess functional outcomes. Results The mean follow-up time was 32 months (range, 1-372), 52 patients died with disease at the final follow-up. Five-year survival rates of high grade sarcoma and low grade sarcoma were 59% and 90%, respectively, with statistical significance (P=0.02). Lung metastasis were demonstrated in 52 patients (27.2%, 52/191), 51 (26.7%, 51/191) had local recurrence. Except the tumor factor, the total complication rate was 50.3%(96/191). Local complications included 33 nonunion (17.3%, 33/191), 39 fracture of the grafts (20.4%, 39/191), 39 infections of the graft (20.4%, 39/191), 15 fracture of internal fixation (7.9%, 15/191), 5 instability or semiluxation of the joint (2.6%, 5/191). The 5-year survival rate of inactivated bone was 55%. On the basis of Mankin functional evaluation, the satisfied rate was 50.3%. At last there were 141 patients (73.8%, 141/191) preserved their extremities. Conclusion Compared to other methods in the same period, EAR method is considered on the same level of safety in oncology, which superiorities are economic-applicable to patients and the well fitness of bone graft with the defects.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).
METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.
RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).
CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins

Background Recently,whether the epithelial flaps should be removed or preserved during the Epi-LASIK and its affection on clinical results are concerned.Objecfive This system analysis was to evaluate and compare the clinical effectiveness between on-flap Epi-LASIK and off-flap epi-LASIK for myopia. Methods A systematic literature retfieval was conducted in the MEDLINE,EMBase,Coehrane Library,CBM disc,CNKI from 2003 through 2009.The possible differences in reepithelization time,pain sensation,and haze after surgery were compared between on-flap and off-flap Epi-LASIK for myopia.The statistical analysis was performed using a RevMan 4.2 software.The data was extracted,and the methodological quality was evaluated by two reviewers independently with weighted mean difierence(WMD)for the effectiveness analysis and odds ratio(OR)for counting variable.The quality of included literature was scored according to the Jadad Scale. Results A total of 8 studies involving 251 patients(502 eyes)were included in the meta-analysis.Of these eight studies.five studies were randomized clinical trials and the other three studies were retrospective cohort studies.Compared with on-flap Epi-LASIK group,off-flap Epi-LASIK group had a better postoperative outcome in the mean reepithelization time(WMD=1.32,95%CI-1.82to-0.82,P<0.01)and pain scores at 3,5 day(WMD=-O.99,95%CI-1.71 to-0.28,P(0.01)(WMD=-0.94.95%CI-1.35 to-0.54,P<0.01)after surgery.No significant difierenees were found in the eye numbers of haze at 1 month(OR=0.62,95%C1 0.34 to 1.12,P=0.11),3 months(OR=0.70,95%C1 0.31 to 1.55,P=0.38)and 6 months(OR=1.14,95%C1 0.58 to 2.26,P=0.71)between these two types of operation.The pain scores at the first day after surgery was not significantly different between these two groups(WMD=-0.17,95%CI -0.55 to 0.20,P=0.37). Conclusion The effectiveness of off-flap Epi-LASIK is superior to on-flap Epi-LASIK for myopia.Some high-quality randomlizd and control studies are needed for the further clinical evaluation.
