For solving the problem that common similarity algorithms are insensitive to the relative differences of different chromatographic fingerprints data, this paper improved the algorithms of improved extent similarity), which named new improved extent similarity. It was confirmed that new improved extent similarity could distinguish) the samples with the same total difference and different distribution of relative differences. by applying) the similarity algorithm to simulated data and the chromatographic fingerprints of nine batches Rukuaixiao tablets. New improved extent similarity could reflect the relative differences of peak areas more sensitively when the relative differences of common peak areas was less than 100%. The result indicates that new improved extent similarity can reflect the large deviation from the established proportion of components, which can be applied to the control of the fluctuation of the established proportion of effective components and the process quality control of Traditional Chinese Medicine .

AlM: To evaluate the clinical effect of 200g/L protein-free calf blood extract eye gel for corneal epithelial defect.METHODS: One hundred and sixty - eight cases of corneal epithelial defect ( 58 cases with herpes simplex keratitis; 24 cases with chemical injury; 85 cases with pterygium operation injury ) were randomly divided into two groups: 84 eyes were treated with protein-free calf blood extract eye gel; 84 cases were treated with basic fibroblast growth factor eye gel ( bFGF ) . The bFGF and protein-free calf blood extract eye gels were used 4 times a day. The treatment course was 7d. Epithelial defect restoration, local symptom and sign were observed.
RESULTS: The difference between pre-treatment and post-treatment was significant ( P<0. 01 ) in the two groups. The effect of protein-free calf blood extract eye gel (83. 3%) group was prior to that of bFGF (69%) for corneal epithelial defect. The effective rate of protein-free calf blood extract eye gel in the herpes simplex keratitis, chemical injury and pterygium operation injury was 72. 4%,69. 2% and 95. 2%. Localized stimulus and adverse reaction of all over the body were not been observed.
CONCLUSlON: Protein-free calf blood extract eye gels is valuable and safe for corneal epithelial defect.

OBJECTIVETo investigate the risk of hidden blood loss about applying rivaroxaban after total hip arthroplasty.

METHODSFrom October 2009 to May 2012,88 patients with femoral head necrosis were treated with primary total hip arthroplasty. All the patients were divided into Rivaroxaban group(44 cases)and control group(44 cases). There were 25 males and 19 females in the Rivaroxaban group, with an average age of (58.48 +/- 15.19) years old; in the control group,24 patients were male and 20 patients were female, with an average age of (61.11 +/- 13.54) years old. The patients in the Rivaroxaban group took Rivaroxaban orally from the first day after operation with a dose of 10 mg each day, and treatment course was 14 days. The patients in the control group took placebo orally at the same time. Dominant blood loss and transfusion were recorded, blood routine examinations were taken before operation and at 3 days after operation. The total blood loss and hidden blood loss were calculated according to the formula.

RESULTSThe mean total blood loss was (1509.56 +/- 325.23) ml and the hidden blood loss was(581.47 +/- 215.01) ml, accounting for (37.88 +/- 10.42)% in the Rivaroxaban group. The mean total blood loss was (1262.30 +/- 397.95) ml and the hidden blood loss was (395.59 +/- 97.33) ml, accounting for (30.62 +/- 0.20)% in the control group. The total blood loss, hidden blood loss and transfusion in the Rivaroxaban group was significantly more than those in control group,b ut there was no significant difference on dominant blood loss between two groups.

CONCLUSIONRivaroxaban increased the overall bleeding risk of total hip arthroplasty, especially hidden bleeding risk, which should be careful used.
