Objective To explore the clinical value of application research in business process reengineering in transferring of inpatients for check-up. Methods We reorganized transferring of inpatients for check-up and service tache by introducing the Systematic Redesign method from the therory of Business Process Reengineering. The reengineered process was adopted and applied in the transferring processes. We randomly selected patients for check-up(126 cases for electrocardiogram,130 cases for Xrayand 128 cases for CT examination)and investigated the time cost for check-up and patients satisfaction rate. The above results were compared with those patients(112 cases for electrocardiogram,112 cases for Xrayand 120 cases for CT examination)before use of reengineered process. Results The time cost for the above mentioned check-up was shorter and patients satisfaction rate were alleviated compared with those before use of reengineered process(U=14.55,12.26,13.57;x2=17.37,14.65,10.75,P<0.01).Conclusion Application of business process reengineering in the transferring process of inpatients for check-up proved pivotal important in that it could shorten time cost for transferring process and improve patients satisfaction rate.It possessed realistic significance for increasing benefit and competitions for hospitals.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.

Objective To investigate the safety and effectiveness of endovascular embolization combined with two-stage stereotacticradiosurgery (SRS)for the treatment of intracranial arteriovenous malformation (AVM). Methods From January 2010 to December 2012,the clinical data of 66 patients treated with endovascular embolization combined with two-stage SRS AVM comprehensive therapy at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were analyzed retro-spectively. They were followed up by imaging. The followed-up time was 7 to 96 months. DSA revealed that the complete disappearance of vascular flow void shadow was regarded as a cure. The patients were divided into either a cured group (n = 29)or a not cured group (n = 37)according whether they were cured or not. The effects of different factors,such as AVM rupture or not,the volume size before embolization,and the degree of embolization on the cure rate of AVM with the comprehensive therapy were observed in both groups,and logistic regression was used to analyze the factors affecting the cure rate of comprehensive therapy. Results (1)There were 22 patients (75. 9%)had ruptured AVMs and 7 (24. 1%)had unruptured AVMs in the cured group. The diameters of the aneurysms < 3 cm and ≥3 cm were in 26 (89. 7%)and 3 (10. 3%)cases respectively. Spetzler-Martin (SM)grades of patients were Ⅰ to Ⅲ. In the not cured group,20 patients (54. 1%)had ruptured AVMs and 17 (45. 9%)had unruptured AVMs. The diameters< 3 cm and ≥3 cm were 18 (48. 6%)and 19 patients (51. 4%)respectively. The SM grade in 34 cases were Ⅰ to Ⅲ. (2)During the follow-up period,29 patients (43. 9%)achieved cure on imaging. The modified Rankin scale (mRS)scores in 64 cases (97%)were 0 to 1. Six patients had complications. (3)Multivariate logistic regression analysis showed that the size of AVM (OR,0. 141,95% CI 0. 035 -0. 570,P < 0. 01)and the degree of interventional embolization (OR,2. 414,95% CI 1. 038 -5. 613,P <0. 05)were the influencing factor of the cure rate. Conclusions Vascular interventional embolization in combination with SRS for the treatment of intracranial AVMs was both effective and safe. The diameter of AVM < 3 cm was the beneficial factor of cure rate of comprehensive therapy. The degree of interventional embolization not reaching cure on imaging was a risk factor for the cure rate of comprehensive therapy.
