Endotoxins are lipopolysaccharides ( LPS) , major component of out wall in Gram-negative bacteria. Often they are considered as "prime criminals" of triggering systemic inflaming reaction such as sepsis, bacteremia and so on. It was found in recent years that bactericidal/permeability-increasing protein, a 55kDa member of lipid-related protein family, was a kind of natural molecule of anti-infection and it has special endotoxin-neutralising activity and antibacterial activity. Comprehensive phase II/III clinical trials demonstrated the feasibility and safety of recombinant BPI. So pharmaceutical corporations are attracted to try to apply it to therapy.

Objective To evaluate the value of echocardiography in diagnosing infective endocarditis (IE) in children. Methods The shape, size, echogenicity, distribution of vegetations and valvular function of the heart were observed by transthoracic echocardiography (TTE) in 30 patients with suspected IE. We correlated TTE ifndings with the results of hemoculture and serologic test. Results Vegetations were observed in all patients by echocardiography:seven patients with tricuspid valve vegetations, two with mitral valve vegetations, three with pulmonary valve vegetations, three with main pulmonary artery vegetations, three with aortic valve vegetations, two with aortic valve abscess, and two with vegetations in right atrium. After anti-infection therapy, the size of vegetations in iffteen patients became smaller and the less echogenic than before. Vegetations disappeared in two patients. Vegetation was recurrent repeatedly in one case. Ten patients recovered after operation. Two severe cases died. Five patients underwent TTE again one week after the previous negative TTE. Of them, echocardiography demonstrated vegetations in three cases. However, no vegetations were found in rest two cases because antibiotics had been used at early stage. In addition, echocardiography demonstrated one patient with mitral valve vegetation. But the lesion was ifnally conifrmed to be operating suture. The sensitivity and specificity of TTE in detecting vegetations were 88.0% and 80.0%, respectively. Blood cultures were positive in twenty-seven cases and were negative in three cases. Conclusions The early diagnosis of IE is important to improve patient′s prognosis. It takes a long time in organism cultivation before achieving the clinical diagnosis. TTE can help obtain an early diagnosis stage of IE, and provide the assessment of size and location of vegetation. It plays an important role in treatment and prognosis prediction.

To evaluate the properties of solidifying volatile oil with graphene oxide, clove oil and zedoary turmeric oil were solidified by graphene oxide. The amount of graphene oxide was optimized with the eugenol yield and curcumol yield as criteria. Curing powder was characterized by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The effects of graphene oxide on dissolution in vitro and thermal stability of active components were studied. The optimum solidification ratio of graphene oxide to volatile oil was 1:1. Dissolution rate of active components had rare influence while their thermal stability improved after volatile oil was solidified. Solidifying herbal volatile oil with graphene oxide deserves further study.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

In order to evaluate the characteristic of porous starch (PS) as the solid dispersions carrier of the total Epimedium flavonoids (TEF), the PS was used. The dissolution of icariin was selected as an indicator to analyze the differences of dissolution between TEF and its solid dispersion. TEF was characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray powder diffraction (XRD). Solid dispersion was irregular block and no powder characteristics of TEF and PS could be seen in SEM, DSC and XRD analysis suggested that TEF may be present in solid dispersion as amorphous substance. The dissolution rate of icariin has been improved significantly when the proportion of TEF and PS was 1:2. PS as a traditional solid dispersion carrier is worthy of further study.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).
METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.
RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].
CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.
