To investigate the anti-pyretic and anti-endotoxin effect of Chinese herb medicine Jinhuaqingre capsules.Thirty healthy male New Zealand rabbits with lipopolysaccharide-induced fever were divided into 5 groups (6 rabbits in each): animals in model group were given normal saline by gavage, animals in positive control group were given aspirin (0.2 g/kg), and animals in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0 or 1.5 g/kg, respectively. The changes in body temperature of rabbits were observed. Fifty healthy Kunming mice were divided into 5 groups (10 mice in each): mice in model group were given normal saline by gavage, mice in positive control group were given aspirin (0.2 g/kg), and those in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0, 1.5 g/kg, respectively. Matrix coloration method was used to detect the degradation rate of endotoxin in mice.The body temperature in rabbits of high and medium dose Jinhuaqingre capsule groups declined significantly 60 min after drug administration, and the temperature of high-dose group returned to the baseline after 300 min; while the body temperature of low-dose group started to decline at 180 min after drug administration. The endotoxin degradation rates in mice of high, medium and low dose groups was (56.73±3.12)%, (47.23±1.77)% and (21.08±2.30)% at 30 min after drug administration; those were (82.76±1.00)%, (64.75±1.77)% and (38.21±1.57)% at 60 min after drug administration, respectively.Chinese herb medicine Jinhuanigre capsules have anti-pyretic and anti-endotoxin effects, which may provide a new option for the treatment of heat-toxin syndrome.

Statins lower the hyperlipidemia and reduce the incidence of cardiovascular events and related mortality. A 60-year-old man who was diagnosed with a transient ischemic attack was started on acetyl-L-carnitine, cilostazol, and rosuvastatin. After rosuvastatin treatment for 4 weeks, the patient presented with sudden onset fever, cough, and dyspnea. His symptoms were aggravated despite empirical antibiotic treatment. All infectious pathogens were excluded based on results of culture and polymerase chain reaction of the bronchoscopic wash specimens. Chest radiography showed diffuse ground-glass opacities in both lungs, along with several subpleural ground-glass opacity nodules; and a foamy alveolar macrophage appearance was confirmed on bronchoalveolar lavage. We suspected rosuvastatin-induced lung injury, discontinued rosuvastatin and initiated prednisolone 1 mg/kg tapered over 2weeks. After initiating steroid therapy, his symptoms and radiologic findings significantly improved. We suggest that clinicians should be aware of the potential for rosuvastatin-induced lung injury.

Thais luteostoma has been utilized as a crude drug whose shell and soft tissue have been widely used for the treatment of heat syndrome in China for thousands of years. The present study was designed to investigate the antipyretic and anti-inflammatory activities of T. luteostoma. T. luteostoma was divided into shell (TLSH) and soft tissue (TLST) samples in the present study. The rat model of yeast-induced fever was used to investigate their antipyretic effects; and the rat model of hind paw edema induced by carrageenan was utilized to study their anti-inflammatory activities, and at the same time, the concentration variations of the central neurotransmitter [prostaglandin E2 (PGE2) and cyclic adenosine monophosphate (cAMP)], inflammatory mediators [tumor necrosis factor (TNFα), interleukin-1β (IL-1), interleukin-2 (IL-2) and interleukin-6 (IL-6)] and ion (Na(+) and Ca(2+)) were also tested. The results showed that TLSH and TLST extracts significantly inhibited yeast-induced pyrexia in rats (P < 0.05), and exhibited more lasting effects as compared to aspirin, and TLSH had the better antipyretic activity than TLST, and that TLSH and TLST could significantly prevent against carrageenan induced paw edema in rats (P < 0.05); and markedly reduced levels of PGE2, cAMP, TNFα, IL-1β, IL-2, IL-6, and Na(+)/Ca(2+). In fever model, TLST could significantly reduce the levels of PGE2 (P < 0.01) in rats' homogenate and TNFα (P < 0.05), IL-1β (P < 0.01) in the plasma than TLSH, whereas TLSH could reduce the content of IL-2 (P < 0.01) and IL-6 (P < 0.01) in plasma and increase the content of Ca(2+) (P < 0.01) in plasma and homogenate more significantly than TLST. In conclusion, T. luteostoma extract has antipyretic and anti-inflammatory activities, which may be mediated through the suppression of production of PGE2, cAMP, Na(+)/Ca(2+), TNFα, IL-1β, IL-2, and IL-6.

OBJECTIVETo evaluate the efficacy and safety of trastuzumab plus different chemotherapy regimens in treatment of patients with HER-2-positive advanced breast cancer.

METHODS132 patients with advanced HER-2-positive breast cancer were treated with trastuzumab plus different regimens. The clinical characteristics, efficacy and toxicity of the 132 patients were retrospectively analyzed.

RESULTSFive patients had complete response (CR), 61 patients had partial response (PR), 39 patients had stable disease (SD), and 27 patients had progressive disease (PD). The objective response rate was 50.0% and the disease control rate was 79.5%. The median progression-free survival was 9.3 months. The median overall survival time was 46.2 months. The 1-, 2-, 5- year survival rates were 98.3%, 81.9% and 40.2%, respectively. Trastuzumab combined with chemotherapy is superior to trastuzumab monotherapy (51.2% vs. 33.3%). The number of metastatic sites, efficacy, different previous treatment lines were independent prognostic factors of PFS (P = 0.002, P < 0.0001 and P < 0.0001, respectively). Visceral metastases, pathological grade, and PFS were independent prognostic factors of OS (P = 0.041, P = 0.001, P = 0.025, P < 0.001, P < 0.0001 and P < 0.0001, respectively). Regarding the toxicities, one case discontinued treatment due to the decrease of left ventricular ejection fraction to 47%, two cases had heartbeat tachycardia, 6 cases had palpitation, 17 cases had a fever during first input trastuzumab. No other serious cardiac toxicity was observed. The most common toxicities were chemotherapy-related hematological and non-hematological toxicities.

CONCLUSIONSTrastuzumab combined with chemotherapy is superior to trastuzumab monotherapy. Patients may get benefits for early use of trastuzumab. Trastuzumab plus chemotherapy is effective and well tolerated in patients with advanced HER-2 positive breast cancer. No heart failure occurred in this series of patients, and cardiac safety seems better than that in Caucasians because of younger age at the onset in Chinese advanced breast cancer patients.

Methimazole (MMI)-induced acute pancreatitis is very rare but severe adverse reaction. A 51-yr-old male developed a high fever, chills, and abdominal pain, two weeks after commencement on MMI for the treatment of Graves' disease. There was no evidence of agranulocytosis, and fever subsided soon after stopping MMI treatment. However, 5 hr after taking an additional dose of MMI, abdominal pain and fever developed again. His symptoms, biochemical, and imaging studies were compatible with acute pancreatitis. After withdrawal of MMI, he showed clinical improvement. This is the first case of MMI-induced acute pancreatitis in Korea. Clinicians should be aware of the rare but possible MMI-induced pancreatitis in patients complaining of fever and abdominal pain.

Pharmacokinetic-pharmacodynamic (PK-PD) modeling was used to characterize the antipyretic and anti-inflammatory effects in rats of Rhein, a major component in rhubarb. Twenty-four healthy male Sprague-Dawley (SD) rats were randomly into four groups, of 6 each. The rats in first group were injected intravenously with lipopolysaccharide (LPS, 100 microg x kg(-1)). The second group rats were given rhubarb decoction (RD, 1.54 g x kg(-1)) by oral administration alone. The rats belonging to third group were administered orally RD 30 min after LPS injection. The rest rats were given normal saline only as control group. Orbital sinus blood sampling was collected at different time points. The Rhein and NO concentration in plasma and body temperature (BT) were measured. Relevant data of PK-PD modeling were performed with Kinetica 5. 0. 11. RD could suppress the rise in BT and plasma NO concentration. The antipyretic and anti-inflammatory responses were best described by a Sigmod-E(max) model. Delay between exposure and response was accounted for by a transit compartment model with two parallel transit compartment chains. The results showed that some parameters such as t1/2, C(max) and AUC were significantly increased in rats treated with LPS, compared to those in rats treated with normal saline. The EC50 for antipyretic effect and decrease of plasma NO concentration was respectively equal to 114.1, 90.80 microg x L(-1). The E(max) for antipyretic effect was about 111% of that for increase in BT after LPS injection. The E(max) for anti-inflammatory action was close to 8.399% of that for elevated NO level after modeling. Meanwhile, there was a difference in pharmacokinetic process of Rhein between the impact of normal saline and LPS. So, it can be concluded that the targets of regulating NO production and BT after RD administration may be at the same location. Not only do that, the antipyretic effect induced by RD maybe completely manifest through reducing the plasma concentration of NO.

In order to discover the mechanism of Xuebijing oral effervescent tablet (XBJOET) to treat infectious diseases, the effect of XBJOET on endotoxin induced rabbit fever and disseminated intravascular coagulation (DIC) was investigated. Auricle microcirculation in rabbit was detected by laser speckle blood perfusion imager system; coagulation function was measured by coagulation analyzer, fibrinolytic system was quantified by Elisa assay and micro thrombosis in tissues was observed with HE staining under light microscope. The results demonstrated that the body temperature of rabbit decreased significantly at 1-3 h after administration with 4.8, 2.4 and 1.2 g x kg(-1) XBJOET to endotoxin induced DIC rabbit model, the auricle microcirculation blood flow in model group (54.45 +/- 14.53) PU was lower than that in control group (77.18 +/- 12.32) PU. The auricle microcirculation blood flow increased markedly and there was significant difference between model group and 1.2 g x kg(-1) XBJOET group. There was significant difference between model group and control group in the content of PAI1 and FIB. The PAI1 levels in model and control groups were (30.48 +/- 2.46) ng x mL(-1) and (20.93 +/- 3.25) ng x mL(-1), respectively. The FIB levels in model and control group were (3.34 +/- 1.09) g x L(-1) and (4.84 +/- 1.10) g x L(-1), respectively. The content of PAI1 in rabbit plasma decreased notably, there were significant differences between model group and 4.8, 2.4 g x kg(-1) XBJOET groups. On the contrary the content of FIB increased. XBJOET possessed pharmacological activities of curing infectious fever and DIC, the mechanism of which is related to amelioration of microcirculation disturbance, inhibition of fibrinolytic system activation and coagulation and micro thrombosis elimination.
