OBJECTIVE: To optimize the preparation process of Xiangsha Liujun Granule. METHODS: By the orthogonal design. taking the rates of recovery of volatile oil, Ginsenoside Re and qualified granules as the indexes, we optimized the oil extracting conditions, the decocting conditions and the conditions of granulation by spayer. RESULTS: The optimum oil ex- tracting conditions for four kinds of herbs(Pericarpium Citri Reticulatae etc.) were that water was 30 times of herbs in weight, soaking time was 3 hours and extracting time 15 hours. The optimum decocting conditions for four kinds of herbs(Fuling etc.) were that water was 15 times of herbs in weight, soaking time was 3 hours and decocting time 4 hours, herbs were decocted twice. The optimum conditions of granulation by sprayer were that the fliud extract was 2 times of Dextrin in weight, the rel- ative density of the fliud extract was 1. 30(measured at 25℃), the voltage of sprayer was 120 volts, the period of shaking bag was 65 times(shaking bag back and forth twice in each period). CONCLUSION: The results of the experiment make it clear that the preparation process of Xiangsha Liu jun Granule is stable and feasible.

Objective:To explore the antipyretic effect on rabbit fever induced by endotoxin and the anti-inflammatory effect on the increase of mouse abdominal cavity capillary permeability caused by 0. 6% glacial acetic acid of Bazhong gardenia. Methods:The rab-bit fever model was made by ear margin vein injection of endotoxin in physiological saline solution, and the mouse inflammation model of abdominal cavity capillary permeability increase was established by 0. 6% glacial acetic acid solution. The animals were respectively intragastrically administrated with gardenia water-soluble effective parts and 70% alcohol-soluble effective parts. The rabbit body tem-perature and mouse celiac fluid absorbance values were detected. The effects of gardenia from different habitats were studied and com-pared. Results:The antipyretic effect of water-soluble effective parts from Bazhong gardenia extract was better than that of gardenia ex-tract from Jiangxi, Hubei and Jiangjin (P<0. 01), and that of alcohol-soluble effective parts from Bazhong gardenia extract was better than that of gardenia extract from Jiangjin and Jiangxi (P<0. 05 or 0. 01). Although compared with that of Hubei gardenia, the anti-pyretic effect of alcohol-soluble effective parts from Bazhong gardenia extract was weaker than that of gardenia extract from Hubei, the difference was not significant (P>0. 05). Bazhong gardenia could inhibit the increase of abdominal blood capillary permeability in mouse inflammation model, and the effect was better than the other gardenia, however without significant difference (P>0. 05). Con-clusion:Bazhong gardenia shows better antipyretic effect compared with that from other habitats.

Objective To determine whether anticoagulation markers can improve mortality prediction in patients of surgical intensive care unit (ICU).Methods A case-control study was adopted,252 patients from Tongji hospital's surgical ICU and 30 healthy control individuals were investigated.The protein C,antithrombin,thrombomodulin,and other coagulation/ inflammatory markers were detected.The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score were obtained.Markers level comparison among survivors,non-survivors and controls were conducted with single factor variance analysis,Kruskal-Wallis test or Mann-Whitney U test.Results Between survivors and non-survivors after 28-day hospitalization,there were significant difference on protein C levels[(70.2 ±22.7)％ vs (48.6 ±29.8)％,t=2.84,P＜0.01],APACHE Ⅱ scores[(21.0±8.2) vs (29.5 ±10.9),t =-2.51,P＜0.05] and prothrombin times[(12.9-± 3.5) s vs (18.8 ± 10.2) s,t =-2.13,P ＜ 0.05].Combining protein C levels with APACHE Ⅱ score could obtain a higher mortality prediction efficiency in patients of surgical ICU than any single marker (AUC =0.806).That protein C concentration less than 47.5％ [OR =6.40,95％confidence interval(CI) 2.526-16.216,P ＜0.001] and APACHE Ⅱ score (OR =1.123,95％ CI 1.012 -1.250,P ＜ 0.05) were the independent risk factors for surgical ICU death.Conclusion Decrease of protein C levels predict increase of mortality risk in patients of surgical ICU,combining protein C with APACHE Ⅱ score can improve the prognostic accuracy for patients of surgical ICU.(Chin J Lab Med,2013,36:339-342)

OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.
