AIM To investigate the effects of stir-frying,processing with butter and carbonizing by stir-frying on oil components in Gleditsiae sinensis Fructus and Gleditsiae Fructus Abnormalis.METHODS The volatile oils and fatty oils were extracted by steam distillation method and Soxhlet extraction method,respectively,after which the extraction rates were determined.GC-MS was applied to analyzing the kinds and relative contents of oil components,after which cluster analysis was performed.RESULTS After the processing,the two medicinal materials demonstrated increased extraction rates of fatty oils and decreased extraction rates of volatile oils(except for processing with butter),the extraction rates of oil components in Gleditsiae sinensis Fructus were higher than those in Gleditsiae Fructus Abnormalis,and the reduced relative contents of toxic olefin benzene components were observable.CONCLUSION The kinds and relative contents of oil components in Gleditsiae sinensis Fructus and Gleditsiae Fructus Abnormalis exist obvious differences,the former displays better medicinal quality,whose processing mechanism in alleviating dryness and strength may contribute to the reduction of relative contents of toxic olefin benzene components.

Objective To investigate and analyze the wounded's stale of ear,nose,throat,neck and head injury in Wenchuan earthquake. Methods The 206 wounded cases,who was treated in No.452 Hospital of People's Liberation Army,were investigated specially with emphasis on injury casue,severity and treatment. Results The injured 165 cases among the 206 were in hospital,while the cases who related to the injury of ear,nose and throat were 37 cases (22.4%). Among the inpatients,the trauma of torhinolaryngology and head and neck included:ear injuries totally 13 cases (including haemotympanum 2 cases),extraneous matter 4 cases,haemorrhagia 4 cases,nasalis and the fracture of nasal bone and nasal sinuses 7 cases (including cerebrospinal rhinorrhea 1 case),zygomatica abscess 1 case,fracture of mandible 4 cases,lip injureies 2 cases and hoarse 2 cases. The inpatients were wounded mostly because of failing and stepping.All the inpatients recovered well after properly management by ENT doctors.Concldusions Maxillofacial injury of the wounded those were medical evacuation in the earthquake area,was ignored more readily comparing to the injury of other spots,so specialist should examine early and treat properly the people as soon as possible.

OBJECTIVETo evaluate the efficacy and safety of long-term treatment with arotinolol in patients with idiopathic dilated cardiomyopathy (IDCM).

METHODSSixty-three patients with IDCM were evaluated at baseline and after 12-month therapy with arotinolol. The conventional therapy for congestive heart failure was continued throughout the study with arotinolol as the only beta-blocker. Left ventricular function was assessed with the New York Heart Association functional class and two-dimensional echocardiography.

RESULTSAfter 12-month arotinolol treatment, there was a significant improvement in left ventricular systolic function. Left ventricular end-systolic dimension significantly decreased from 59.52 +/- 8.83 mm to 50.89 +/- 8.17 mm (P < 0.001). Left ventricular ejection fraction significantly increased from 27.39% +/- 7.94% to 41.13% +/- 9.45% ( P < 0.001). Left ventricular mass index decreased from 150.47 +/- 42.42 g/m2 to 141.58 +/- 34.36 g/m2 (P < 0.01). No adverse events leading to premature discontinuation of study drug occurred.

CONCLUSIONIn this preliminary study, 12-month arotinolol treatment has a favorable effect on left ventricular function in patients with IDCM, and it is safe and well tolerated.

OBJECTIVETo explore the correlation between the dosage of corticosteroid, time of onset and incidence of osteonecrosis (ON) in patients with SARS.

METHODSFrom July 2003 to January 2004, general survey carried out for ON in 551 patients with SARS. Five hundred and fifty-one patients except 12 were administrated by corticosteroid from 80 mg to 30 000 mg. The age of patients was (33 +/- 9) years old ranging from 19 to 59 years old. One hundred and thirty-one were male, and four hundred and twenty were female. MRI and X-ray film were taken in all patients including both hips, knees, shoulders, ankles and wrists. CT scan was taken in partial patients. Common classification system were used for staging of hip (ARCO), knee (Lotka) and shoulder (Cruess). Independent test, rank-sum test and multiple factor logistic regression analysis were used for statistical analysis.

RESULTSNo osteonecrosis was detected in 12 patients without corticosteroid. Osteonecrosis was detected in 176 patients (32.7 percent) among 539 patients. There were ON of femoral head in 130 cases (210 hips), ON of knee in 98 cases (130 knees), ON of humeral head in 21 cases (36 shoulders), ON of talus and calcaneus in 16 cases (26 ankles), ON of scaphoid and lunate in 11 cases (17 wrists), ON of patella in 3 cases (4 patella), ON of ilium in 1 case and bone infarction (femur, tibia) in 18 cases. One hundred and nineteen cases (195 hips) with ONFH were in stage I (IA 45 hips, IB 77 hips, IC 73 hips). Eleven cases (15 hips) were in stage II. All osteonecrosis of the knee and humoral head was stage I. Thirty-four patients with ON had one joint affected, 45 patients had 2 joints, 93 patients had more than 3 joints. The dosage of corticosteroid was (5842 +/- 4988) mg in ON group and (2719 +/- 2571) mg in non-ON group (P < 0.0001). The duration of steroid was (38 +/- 17) d in ON group and (27 +/- 15) d in non-ON group (P < 0.01). The dosage of pulse treatment was (340 +/- 207) mg/d in ON group and (211 +/- 160) mg/d in non-ON group (P < 0.01). The duration of pulse treatment was (28 +/- 13) d in ON group and (18 +/- 11) d in non-ON group (P < 0.01). All patients with ON were detected within 6 months from administration.

CONCLUSIONAbout one-third patients with SARS who were treated with a high dose of corticosteroid occurred osteonecrosis. ON is frequently multiple focuses. The actual time of onset of ON is early of steroid used. MRI is golden standard for early diagnosis of ON. The patients who were treated with a high dose of corticosteroid should be inspected initially by MRI.

Halofuginone (HF) is a derivative of dichroine which is the extract of traditional Chinese medicine. It is widely used as an efficient anticoccidial drug. Recent studies have found that HF has unique biological activities, showing great potential capacities in the treatment of autoimmune diseases. In the article, we summarized the therapeutic effects of HF in a variety of autoimmune diseases and its mechanism, providing references for further clinical studies of HF.

BACKGROUNDCoronary artery disease (CAD) is generally considered as a disease of middle-aged men. It is widely accepted that the risk for CAD of premenopausal women is low because of hormone protection. Based on our clinical experience, more and more premenopausal women suffer from angina and myocardial infarction without adequate concern. Even now, there are still limited detailed data to describe the characteristics, mechanism and prognosis of premenopausal CAD patients. This article aimed to analyze the clinical and angiographic characteristics of premenopausal women with CAD.

METHODSA total of 565 premenopausal women and 721 postmenopausal women (56 - 60 years old) who underwent coronary angiography for the first time from April 2004 to December 2007 were enrolled. The clinical data and coronary angiographic characteristics (presence, localization, length and severity) were compared between the premenopausal and postmenopausal CAD groups.

RESULTSPremenopausal CAD patients presented less frequently with hypertension, diabetes mellitus and dyslipidemia compared with postmenopausal CAD patients (55.0% vs 66.0%, 15.0% vs 31.5%, 23.9% vs 37.4%, respectively; all P < 0.05). Although we found more frequent involvement of single vessel in premenopausal CAD (43.2% vs 26.9%, P = 0), and triple vessels in postmenopausal (56 - 60 years old) CAD patients (33.8% vs 20.4%, P = 0), much more severe lesions (> or = 90%) at left main (2.9% vs 1.1%, P = 0.048) and proximal left anterior descending artery (LAD) (28.2% vs 16.6%, P = 0) in the premenopausal CAD group were found.

CONCLUSIONPremenopausal women with chest discomfort are always found to have obvious atherosclerosis, more inclined to be located at the left main and proximal LAD, which is a strong predictor of an adverse clinical outcome.
