CONCLUSION: The modified hydroxyapatite implant in scleral shell can maintain the normal anatomy of the orbital tissue, and also can get full eyes socket and good activity, It was an easy and simple surgery which could obtain satisfactory clinical effect and less complications.

Abtract: Acute coronary syndrome is a common clinical and frequently occurring disease, belonging to the chest discomfort, heartache, and true heart pain of TCM category. The clinical observation shows that the heat and blood stasis, and poison damage heart nutrient is one of the important mechanisms of triggering coronary syndrome. Therefore, the method of promoting blood circulation to remove meridian obstruction and the Qing Ying detoxication was established as the basic treatment, and Danshen Tongluo Jiedu Decoction is applied as the main formula. According to the different types of disease and syndrome differentiation, flexible modification can achieve good efficacy. It is expected that these will provide new ideas and methods for clinical treatment of acute coronary syndrome.

Objective To investigate the related clinical factors and homology of strains in Stenotrophomonas maltophilia (S. Maltophilia) infections in 15 patients with liver transplantation. Methods Fifteen patients with S. Maltophilia infection from September to December 2006 were enrolled and their clinical data were collected. Minimal inhibitory concentrations (MICs) of 10 antimierobial agents against S. Maltophilia were determined by Etest strips. Antibiogram was carried out by resistance analysis assembly with WHONET 5 software. The genomic DNA of all the isolates was digested with Xbal and subjected to pulse-field gel electrophoresis (PFGE). Results All patients received mechanical ventilation during the treatment and had a history of long-term use of extended-spectrum β-lactamases and quinolones. MICs of 10 antimicrobial agents indicated that S. Maltophilia were susceptible to several antimicrobial agents including compound sulfamethoxazole and ciprofloxacin, but the best active agent against these resistant isolates was minocycline in vitro. The results of all 15 S. Maltophilia antibiograms were accordance with PFGE patterns. All 15 S. Maltophilia isolates were classified as 2 PFGE patterns: 9 for pattern A and 6 for pattern B. Conclusion Mechanical ventilation might be associated with the S. Maltophilia septicemia in patients with liver transplantation.

Objective To explore the effect of whole course integrated health education on depressive emotion and self-concept modification in depressive patients and to improve their psychological rehabilitation. Methods Sixties depressive inpatients treated with antidepressive drugs were randomly assigned to receive supportive psychological nursing and general health education (control group 28) or whole course integrated health education (experimental group 32). Hamilton Depression Scale ( HAMD), Tennessee Self-Concept Scale (TSCS) and Symptom Checklist 90(SCL-90) were used before and after intervention to evaluate the clinical effects of two groups. Results Before interventions,the total scores of HAMD,TSCS and SCL-90 were (24.8 ±4. 3) ,(249.68 ±16.23) and(136.39±34.26)in experimental group and (24. 9 ±4. 2) , (248. 74 ± 17. 32) and( 136. 52 ± 35.04) in control group, with no significant difference between two groups (all P ＜ 0.01). After intervention, the total scores of HAMD, TSCS and SCL-90 were (19.7±2.8),(263.55±19.53) and (114.22 ± 18. 75) in experimental group and (22.4 ± 3. 3), (253. 66 ± 18. 37) and (134. 56 ± 32. 64) in control group, with significant difference between two groups (all P＜0.01). Conclusions Whole course integrated health education can improve depressive emotion of patients with depression, develop their positive self-concept and boost their mental health level.

The teaching method, teaching process and teaching model of programming course were reformed in Beijing University of Traditional Chinese Medicine by combining task-driven and flipped classroom teaching con-cept with BB network platform to provide a free and open environment for students in order to train their capability of analyzing and solving problems and the skills of independent learning and life-long learning. Good results were achieved in two rounds of task-driven plus flipped classroom teaching, which are of significance for the teaching model and teaching structure reform of other courses.

Objective To study the influence of carboxymethyl-chitosan(CM-chitosan)on chondro- cyte apoptosis induced by recombinant human interleukin-1?(rhIL-1?)and explore its mechanism.Methods Rabbit chondrocytes were isolated and cultured.Chondrocytes were pretreated with different concentrations of CM-chitosan for 1 h,then 10 ng/ml IL-1?were added into the culture medium.After 24 h,the apoptotic rates of chondrocytes were measured by flow cytometry with AnnexinⅤ-FITC and PI staining.The morphology of nuclei was observed by fluorescent microscopy with Hoechst 33342 staining.The mitochondrial membrane po- tentials were tested by confocal laser scanning microsocopy with Rhodamine-123 and ATP contents were mea- sured by luciferase reaction.Results CM-chitosan could inhibit chondrocyte apoptosis and restore the func- tion of mitochondria induced by IL-113 in a dose-dependent manner.Conclusion CM-ehitosan can inhibit chondrocyte apoptosis by protecting mitochondrial function.

OBJECTIVE: Using the method of lactate dehydrogenase (LDH) assay, to observe the activities of rat cerebral microvascular endothelial cells (CMECs) intervened by Tongluo Jiunao Injection (TLJNI), a traditional Chinese compound drug removing toxin to dredge brain collaterals, and then further study the effects of different kinds of conditioned mediums (CMECs-CM) of cerebral microvascular endothelial cells on ischemia and ischemia/reperfusion cerebral cortex cells, and to probe into the drug pharmacological mechanisms of CMECs in modulating the neurons. METHODS: Three kinds of CMECs (normal, ischemic and ischemic/reperfusional) were all treated by TLJNI previously, and then the three pairs of CMECs-CM without serum were collected respectively for LDH assay. Rat cerebral cortex neurons were also primarily cultured and then divided into similar three groups (normal, ischemic and ischemic/reperfusional). The neuron responses caused by CMECs-CM at different concentrations were observed by using LDH transudation rate assay. RESULTS: The LDH release values of ischemic and ischemic/reperfusional CMECs with TLJNI treatment were obviously reduced (P<0.01) compared with the same kinds of CMECs untreated. For ischemic neurons, both conditioned medium of ischemic CMECs (Is-CM) and conditioned medium of ischemic CMECs with drug treatment (IsT-CM) in high concentration of 100% increased the LDH transudation rate (P<0.01), while in low concentration of 10%, IsT-CM reduced the transudation rate (P<0.05). For ischemia/reperfusion neurons, all kinds of CMECs-CM reduced the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, 10% or 50% showed relatively stronger effects, and both conditioned medium of normal CMECs (N-CM) group and conditioned medium of ischemic/reperfusional CMECs (Rp-CM) group had statistical significance (P<0.05 or P<0.01). For normal neurons, all kinds of CMECs-CM increased the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, only conditioned medium of normal CMECs (N-CM) had statistical significance (P<0.05 or P<0.01). CONCLUSION: The study shows that TLJNI is capable of preventing the damage of CMECs from both ischemia and ischemia/reperfusion states. Chinese drug can restrain the brain ischemia and ischemia/reperfusion damage by the media that CMECs modulate the neurons, demonstrating the pharmacological mechanisms of TLJNI. This work also indicates that there exist some active substances against ischemia/reperfusion injury secreted from CMECs-CM with TLJNI treatment.
