Issues such as the scientific management system and information technology in the building of archives management, technical and operational training, reward and punishment system, and intiatives of staff are focused on. The management level of medical engineering thus has been furtherly improved.

OBJECTIVE:To study the inhibitory action of Sarcandra glabra injection (ZJF) on tumor growth of SGC-7901 transplantation tumor in nude mice and its induction on apoptosis. METHODS:SGC-7901 transplantation tumor nude mice model was established then the model mice were assigned to blank,positive control,ZJF high-dose and low-dose (3,1.5 g?kg-1) groups. After treatment with ZJF for 14 days,the indexes of thymus and spleen,numbers of peripheral red blood cells,white cells and platelet were measured; the tumor-inhibition rate was computed; the ultrastructure of tumor tissues was observed,and the apoptosis of implanted tumor cells was observed. RESULTS:As compared with blank group,no significant change was noted in the indexes of thymus and spleen and peripheral hemogram. The differences between high-dose ZJF group and low-dose ZJF group were greatly significant in both the inhibition rate of SGC-7901 transplantation tumor (42.8% vs. 39.9%) and the apoptotic rate of tumor tissues [(9.3?0.15)% vs.(8.18?0.08)%].One or more apoptotic bodies formed after medication. CONCLUSION:ZJF can promote the presence of apoptotic body and induce apoptosis thus inhibiting the growth of SGC-7901 transplantation tumor in nude mice; however,it had little impact on the thymus and spleen and peripheral hemogram.

Objective:To prepare curcumin liposome and investigate its stability.Methods:Curcumin liposome was prepared by the reversed-phase evaporation method and purified by exclusion chromatography with Sephadex-50.The optimum formation was selected by means of orthogonal design of experiment;Centrifugal acceleration experiment and determination of leakling ration were served to proved the liposome stability.Results:The optimum formula was as follows:the ratio of lecithin to drug was 60∶1;lecithin:cholesterol was 4∶1;pH of PBS was 6.5,ultrasonic time was 5min.The average entrapment efficiency for curcumin was 95.06%.Conclusion:The selected formulation and preparation technique of curcumin liposome is reasonable in prescription,practicable in techniques,high in encapsulation efficiency and good in stability.

Objective:By adopting network pharmacology to study the mechanism of Yinchen-Erchen Decoction in treating non-alcoholic steatohepatitis (NASH). Methods:TCMSP was used to collect the chemical constituents of Yinchen-Erchen Decoction, and the effective active ingredients were obtained. Then the target of action was speculated. GeneCards database was used to collect the related genes of NASH. The visualized network of drug-target and disease-target was established by the Cytoscape software. After the analysis of key target genes, PPI network map was established to enrich GO and KEGG pathways based on key target proteins. Results:A total of 45 active ingredients and 114 drug target proteins, 463 NASH related genes and 33 drug and disease targets were obtained from the main chemical constituents of Yinchen-Erchen Decoction. The protein interaction network found that IL6, CASP3, MYC may be the key targets of Yinchen-Erchen Decoction in the treatment of NASH. GO and KEGG enrichment analysis identified 34 and 79 signal pathways related to inflammation, cell apoptosis, diabetes, NAFLD, cancer and so on. Conclusions:Yinchen-Erchen Decoction has multi-pathway and multi-target characteristics in treating NASH. It reveals the key targets, biological processes and signal pathways involved, and provide reference and basis for the following study.

OBJECTIVETo retrospectively analyze therapy comparison between hinged external fixator combining with internal fixation, soft tissue repair and plaster fixation after routine surgery for terrible triad of the elbow.

METHODSFrom January 2003 to June 2011,26 patients with terrible triad of the elbow (posterior dislocation associated with fracture of both the radial head and the ulnar coronoid process) were treated respectively by unilateral hinged external fixator and plaster fixation. Fourteen patients were treated with external fixator combining with internal fixation, soft tissue repair and reconstruction, including 8 males and 6 females,ranging in age from 20 to 62 years with an average of (33.60 +/- 8.53) years. The mean time of fixation was 7.5 weeks (ranged, 6 to 8 weeks), and forearm rotation exercise was performed after the first day of operation, elbow flexion and extension activities after 4 to 6 days. Twelve patients were treated with plaster external fixation combining with open reduction and internal fixation,including 8 males and 4 females,ranging in age from 21 to 63 years with an average of (34.80 +/- 7.41) years. The mean time of plaster fixation was 30.4 days, and functional exercise was carried out after 4 to 6 weeks of plaster removal. JOA assessment score were used to evaluate the elbow joint function.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 36 months,with an average of 18.6 months. The mean time of fracture healing was (8.6 +/- 3.1) weeks in plaster group and (9.0 +/- 2.7) weeks in fixator group, with no statistical difference between the two groups (t =1.47, P > 0.05). The function and are of motion in plaster group and fixator group showed significant difference. While the pain, articular instability and deformity showed no statistical difference. The total assessment score between two groups indicated markedly difference (t = -2.66, P < 0.01).

CONCLUSIONHinged external fixator can enhance lateral stability of elbows,benefit the reduction of fracture dislocation, guarantee early and safe functional exercise, prevent elbow stiffness, and reduce heterotopic ossification. In treating terrible triad of the elbow, the hinged external fixator is superior to other therapies with respect of improving the function of elbow joint.
