To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.

BACKGROUND/AIMS: The gastrointestinal (GI) tract often becomes involved in patients with systemic amyloidosis. As few GI amyloidosis data have been reported, we describe the clinical features and outcomes of patients with pathologically proven GI amyloidosis. METHODS: We identified 155 patients diagnosed with systemic amyloidosis between April 1995 and April 2013. Twenty-four patients (15.5%) were diagnosed with GI amyloidosis using associated symptoms, and the diagnoses were confirmed by direct biopsy. RESULTS: Among the 24 patients, 20 (83.3%) had amyloidosis light chain (AL), three (12.5%) had amyloid A, and one (4.2%) had transthyretin-related type amyloidosis. Their median age was 57 years (range, 37 to 72), and 10 patients were female (41.7%). The most common symptoms of GI amyloidosis were diarrhea (11 patients, 45.8%), followed by anorexia (nine patients, 37.5%), weight loss, and nausea and/or vomiting (seven patients, 29.2%). The histologically confirmed GI tract site in AL amyloidosis was the stomach in 11 patients (55.0%), the colon in nine (45.0%), the rectum in seven (35.0%), and the small bowel in one (5.0%). Patients with GI involvement had a greater frequency of organ involvement (p = 0.014). Median overall survival (OS) in patients with GI involvement was shorter (7.95 months; range, 0.3 to 40.54) than in those without GI involvement (15.84 months; range, 0.0 to 114.53; p = 0.069) in a univariate analysis. A multivariate analysis of prognostic factors for AL amyloidosis revealed that GI involvement was not a significant predictor of OS (p = 0.447). CONCLUSIONS: The prognosis of patients with AL amyloidosis and GI involvement was poorer than those without GI involvement, and they presented with more organ involvement and more advanced disease than those without organ involvement.

The method of monoclonal antibody-based immunoassay has a great importance in the study of quality control of traditional Chinese medicine (TCM) and detection of trace components in vivo animals. Synthesis of small molecule artificial antigen is the prerequisite for the establishment of this method. In present study, catalpol-BSA was synthesized by sodium periodate oxidation method. Matrix-assisted laser desorption ionization-time-of-flight mass spectrometry ( MALDI-TOF-MS) and molecular exclusion chromatography showed that catalpol was successfully conjugated with BSA. The mice could specifically produce anti-catalpol antibodies with titer up to 1:8000. The artificial antigen of catalpol was successfully synthesized.

Pentraxin 3 (PTX3) was identified as a marker of the inflammatory response and overexpressed in various tissues and cells related to cardiovascular disease. Honokiol, an active component isolated from the Chinese medicinal herb Magnolia officinalis, was shown to have a variety of pharmacological activities. In the present study, we aimed to investigate the effects of honokiol on palmitic acid (PA)-induced dysfunction of human umbilical vein endothelial cells (HUVECs) and to elucidate potential regulatory mechanisms in this atherosclerotic cell model. Our results showed that PA significantly accelerated the expression of PTX3 in HUVECs through the IkappaB kinase (IKK)/IkappaB/nuclear factor-kappaB (NF-kappaB) pathway, reduced cell viability, induced cell apoptosis and triggered the inflammatory response. Knockdown of PTX3 supported cell growth and prevented apoptosis by blocking PA-inducted nitric oxide (NO) overproduction. Honokiol significantly suppressed the overexpression of PTX3 in PA-inducted HUVECs by inhibiting IkappaB phosphorylation and the expression of two NF-kappaB subunits (p50 and p65) in the IKK/IkappaB/NF-kappaB signaling pathway. Furthermore, honokiol reduced endothelial cell injury and apoptosis by regulating the expression of inducible NO synthase and endothelial NO synthase, as well as the generation of NO. Honokiol showed an anti-inflammatory effect in PA-inducted HUVECs by significantly inhibiting the generation of interleukin-6 (IL-6), IL-8 and monocyte chemoattractant protein-1. In summary, honokiol repaired endothelial dysfunction by suppressing PTX3 overexpression in an atherosclerotic cell model. PTX3 may be a potential therapeutic target for atherosclerosis.

OBJECTIVETo investigate the effects of application of intermittent hemofiltration combined with hemoperfusion (HP) in the early stage of severe burn in the prevention and treatment of sepsis.

METHODSForty severely burned patients, admitted to our burn ward from June 2011 to March 2013, conforming to the study criteria, were divided into conventional treatment group (CT, n=20) and blood purification group (BP, n=20) according to the random number table. Patients in group CT received CT according to the accepted principles of treatment for a severe burn. Patients in group BP received CT and intermittent hemofiltration combined with HP once respectively on post injury day (PID) 3, 5, and 7, spanning 6 to 8 hours for each treatment. On PID 3, 5, 7, 10, and 14, body temperature, heart rate, and respiratory rate were recorded; white blood cell count (WBC), neutrophil granulocytes, blood urea nitrogen (BUN), and creatinine were determined; levels of IL-1, IL-6, TNF-α, and high-mobility group box 1 (HMGB1) in serum were determined by ELISA; level of LPS in serum was determined with the chromogenic substrate limulus amebocyte lysate method; level of procalcitonin (PCT) in serum was determined by double antibody sandwich immune chemiluminescence method. The symptoms and signs of sepsis were observed during the treatment. Data were processed with Fisher's exact test, chi-square test, analysis of variance for repeated measurement, and LSD-t test.

RESULTS(1) Except for that on PID 5, the mean body temperature of patients in group BP was significantly lower than that of group CT at each of the rest time points (with t values from 1.87 to 2.97, P values below 0.05). The heart rate was significantly slower in patients of group BP than in group CT from PID 3 to 14 (with t values from 1.78 to 3.59, P values below 0.05). Except for that on PID 3, the respiratory rate of patients in group BP was significantly slower than that of group CT at each of the rest time points (with t values from 1.93 to 2.85, P values below 0.05). (2) The levels of WBC, neutrophil granulocytes, BUN, and creatinine of patients in group BP were significantly lower than those of group CT (with t values from 1.78 to 4.23, P values below 0.05). (3) Except for that on PID 3, the level of IL-1 of patients in group BP was significantly lower than that of group CT at each of the rest time points (with t values from 1.97 to 4.16, P values below 0.05). Except for that on PID 7, the level of IL-6 of patients in group BP was significantly lower than that of group CT at each of the rest time points (with t values from 2.11 to 6.34, P values below 0.05). The levels of TNF-α and HMGB1 of patients in group BP were significantly lower than those of group CT from PID 3 to 14 (with t values from 1.98 to 5.29, P values below 0.05). (4) On PID 3, 5, 7, 10, and 14, the levels of LPS and PCT of patients in group BP were respectively (0.23 ± 0.07), (0.27 ± 0.09), (0.22 ± 0.06), (0.20 ± 0.08), (0.15 ± 0.07) EU/mL, and (0.44 ± 0.12), (0.67 ± 0.13), (0.74 ± 0.13), (0.64 ± 0.12), (0.71 ± 0.10) ng/mL, and they were lower than those of group CT [(0.37 ± 0.08), (0.45 ± 0.09), (0.56 ± 0.09), (0.48 ± 0.08), (0.40 ± 0.08) EU/mL, and (0.74 ± 0.11), (1.16 ± 0.12), (1.40 ± 0.13), (1.55 ± 0.15), (1.49 ± 0.14) ng/mL, with t values from 1.88 to 3.43, P values below 0.05]. (5) The incidence of sepsis of patients in group BP was obviously lower than that of group CT (χ² = 6.94, P<0.01).

CONCLUSIONSIntermittent hemofiltration combined with HP can effectively improve blood biochemical indexes and vital signs and reduce the occurrence of burn sepsis by decreasing the levels of proinflammatory cytokines, LPS, and PCT.

OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.

METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.

RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).

CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.

OBJECTIVETo compare the efficacy and safety of four different regimens for pediatric severe aplastic anemia (SAA) with immuno-suppressive therapy (IST) with or without combined human granulocyte colony-stimulating factor (G-CSF).

METHODThe authors retrospectively analyzed 105 children with SAA treated with IST with or without G-CSF in the hospital from February 2000 to September 2010. Regimen A, without G-CSF in the whole treatment, was used to treat Group A patients, n = 27; Regimen B, G-CSF, was initiated in Group B, n = 24, before the IST until hematologic recovery; Regimen C, G-CSF, was used together with the IST for Group C patients, n = 24, until hematologic recovery; Regimen D,G-CSF was used for Group D, n = 30, after the end of IST until hematologic recovery. The response rate, relapse rate, mortality, infection rate, infection-related death rate, risk of evolving into MDS/AML, survival rate, factors affecting the time of event-free survival and so on.

RESULT(1) The response (CR+PR) rates 4, 6, 12 and 24 months after IST of the whole series of 105 SAA children were 50.5% (7.6%+42.9%) , 60.0% (21.9%+38.1%) , 67.6% (38.1%+29.5%) and 69.5% (40.0%+29.5%) respectively. The 2-year survival rate was 90.5%; the follow-up of the patients for 13 years showed that the whole survival rate was 87.6%. (2) The differences of the response rates 4, 6, 12 and 24 months after IST of the 4 groups were not significant (P > 0.05). (3) No significant differences were found in the mortalities 4, 6, 12 and 24 months among the 4 groups (P > 0.05). (4) Of the 105 patients, 4 children had relapsed disease in the period of time from 6 to 24 months after IST. All the four patients belonged to the groups with G-CSF. (5) The use of G-CSF could not decrease the infection period before IST (day) (P = 0.273), and it had no impact on the infection rate after IST (P = 0.066). It did not reduce the rates of septicemia and infectious shock. And to the infection-related death rate no significant conclusion can be made. (6) Follow up of the patients for 13 years, showed that 2 had the evolution to MDS/AML in the 105 patients and the two children belonged to the groups with G-CSF. (7) Kaplan-meier curve analysis did not show any differences in the survival rates of the four groups. (8) Cox regression analysis showed that the use of G-CSF had no benefit to the patients' long term survival. While the age of diagnosis and the infection history before IST were significantly related to the patients' long term survival.

CONCLUSIONThe use of G-CSF did not contribute to the early response and could not reduce the infection rate, infection-related death rate and the patients' long term survival. There were no significant differences in the survival rates of the four groups. Attention should be paid to the risk of the evolution to MDS/AML.

Oxidation method with sodium iodide was used to synthesize immunogenic antigen (PF-BSA) and coating antigen (PF-OVA) of paeoniflorin. UV spectroscopy showed that paeoniflorin was successfully conjugated with BSA and OVA. After immunized by PF-BSA, the mice can produce anti-paeoniflorin antibodies specifically. The ELISA test results showed the high titer (1:12 800) and specificity (IC50 = 0.791 mg x L(-1)) of the antiserum from mice injected with PF-BSA. Also, the antiserum showed low cross activities against nine traditional Chinese medicine (TCM) of small molecules. These artificial antigens were successfully synthesized and the anti-paeoniflorin antibody well prepared, which provides the experimental basis for the further study of ELISA and its kit.
