AIM: To evaluate the influences of triptolide on serum cytokines, symptoms and pulmonary function in patients with steroid - resistant asthma, so as to investigate if there is therapeutic effect of triptolide on these patients. METHODS: Sixteen patients with steroid - resistant asthma were randomly divided into two groups (A and B, n =8 for each group). All of the patients took procaterol (50 - 100 μg/d) and theophylline (400 mg/d) orally as baseline treatment. Additionally, triptolide was prescribed for group A (33 μg, orally, three times per day for 4 weeks). Asthmatic symptom score calculation, serum cytokines ( interferon - γ, IFN - γ; interleukin - 4, IL - 4; and interleukin - 5, IL - 5)determination and pulmonary function test (FVC%, FEV1%, PEF%, V50% and V25% ) were undertaken before and at the end of the study. RESULTS: At baseline, no significant difference was found between group A and group B with respect to the above mentioned indices. Following the administration of triptolide, group A had significantly increased serum IFN -γlevel, FVC%, FEV1%, PEF%, V50% and V25%, and significantly decreased asthmatic symptom score and serum IL-4, IL-5 levels (P<0.01 compared with baseline in the same group, and P<0.05 compared with group B at the end of the study). Compared with baseline, no significant change was observed for group B regarding all the indices at the end of the study. CONCLUSION: Triptolide in combination with procaterol and theophylline may be a novel and effective strategy for the treatment of steroid - resistant asthma.

AIM: To evaluate the pulmonary function in patients with type 2 diabetes mellitus in order to identify whether the lung is a target organ of chronic pathologic changes in diabetes mellitus. METHODS: Pulmonary ventilation function and diffusion capacity were studied in 107 patients with type 2 diabetes mellitus and 61 healthy subjects matched for age and sex. Glycosylated hemoglobin (HbA1c), urine albumin excretion rate (AER), fundus examination and nerve conduction velocity were included as parameters of glycemic control and diabetic microangiopathies. RESULTS: Pulmonary ventilation function was similar in type 2 diabetic group and the control. Compared with the control, carbon monoxide diffusion capacity (DLCO) and DLCO corrected by alveolar volume (DLCO/VA) were significantly lower in type 2 diabetic group (P<0.05). DLCO and DLCO/VA were inversely correlated with microangiopathy score (r: -0.291, -0.324, respectively, P<0.01). Furthermore, DLCO/VA was negatively correlated with age and duration of diabetes mellitus (r: -0.269, -0.236, respectively, P<0.05). CONCLUSIONS: Pulmonary ventilation function is normal in patients with type 2 diabetes mellitus, but their diffusion capacity is impaired. It suggests that the lung may also be the target organ of the chronic pathologic changes of diabetes mellitus.

<p><b>OBJECTIVE</b>To identify valid measures for preventing outbreaks of severe acute respiratory syndrome (SARS) among protected healthcare workers in isolation units.</p><p><b>METHODS</b>Architectural factors, admitted SARS cases and infection of healthcare workers in different isolation wards between January 30 and March 30, 2003 were analyzed.</p><p><b>RESULTS</b>Four types of isolation wards were analyzed, including the ward where the thirty-first bed was located on the twelfth floor, the laminar flow ward in the Intensive Care Unit where the tenth bed was located on the fifteenth floor, the ward where the twenty-seventh bed was located on the thirteenth floor of the Lingnan Building, and thirty wards on the fourteenth to eighteenth floors of the Zhongshan Building. The ratios (m(2)/m(3)) of the area of the ventilation windows to the volume of the rooms were 0, 0, 1:95 and 1:40, respectively. Numbers of SARS cases in the wards mentioned above were 1, 1, 1 and 96, respectively. Total times of hospitalization were 43, 168, 110 and 1272 hours, respectively. The infection rates of the healthcare workers in the areas mentioned above were 73.2%, 32.1%, 27.5% and 1.7%, respectively. The difference in the infection rates was of statistical significance.</p><p><b>CONCLUSIONS</b>Isolating SARS cases in wards with good ventilation could reduce the viral load of the ward and might be the key to preventing outbreaks of SARS among healthcare workers along with strict personal protection measures in isolation units.</p>

<p><b>OBJECTIVE</b>To describe a hospital outbreak of severe acute respiratory syndrome (SARS) and summarize its clinical features and therapeutic approaches.</p><p><b>METHODS</b>The outbreak started with a SARS patient from the community, and a total of 96 people (76 women and 20 men, mean age (29.5 +/- 10.3) years, 93.8% of whom were health care workers) who had exposure to this source patient became infected in a short time. Clinical data in this cohort were collected prospectively as they were identified.</p><p><b>RESULTS</b>(1) The incubation period ranged from 1 to 20 (mean: 5.9 +/- 3.5) days. The duration of hospitalization was (17.2 +/- 8.0) days. (2) The initial temperature was (38.3 +/- 0.6) degrees C, while the highest was (39.2 +/- 0.6) degrees C (P < 0.001), with fever duration of (9.0 +/- 4.2) days. (3) Other most common symptoms included fatigue (93.8%), cough (85.4%), mild sputum production (66.7%), chills (55.2%), headache (39.6%), general malaise (35.4%) and myalgia (21.9%). (4) The radiographic changes were predominantly bilateral in the middle or lower lung zones. The number of affected lung fields was 1.2 +/- 0.8 on presentation, which increased to 2.9 +/- 1.4 after admission (P < 0.001). The interval from the beginning of fever to the onset of abnormal chest radiographs was (3.5 +/- 2.3) days, which increased in size, extent, and severity to the maximum (6.7 +/- 3.5) days later. The time before the lung opacities were basically absorbed was (14.9 +/- 7.8) days. (5) Leukopenia was observed in 67.7% of this cohort. The time between the onset of fever and leukopenia was (4.4 +/- 2.3) days, with the lowest white blood cell count of (2.80 +/- 0.72) x 10(9)/L. (6) The lowest arterial oxygen saturation was (94.8 +/- 3.1)% with supplementary oxygen. (7) Antibiotical therapies included tetracyclines (91.0%), aminoglycosides (83.3%), quinolones (79.2%); 18.8% of the patients received a combination of tetracyclines and aminoglycosides, while 11.5% received a combination of tetracyclines and quinolones, and 63.5% received a combination of tetracyclines, aminoglycosides and quinolones. Vancomycin was used in 13.5% of the patients. (8) 68.8% of the patients were treated with methylprednisolones for a mean interval of (4.9 +/- 2.4) days. The initial dose was (67.3 +/- 28.2) mg/d and the maximal dose was (82.4 +/- 30.5) mg/d. (9) Human gamma-globulin, interferon-alpha, antiviral drugs (oral ribavirin or oseltamivir) were used respectively in 68.6%, 46.9% and 92.7% of the patients. (10) Ninety-five patients (99.0%) had a complete clinical recovery, and only 1 patient (1.0%) died.</p><p><b>CONCLUSIONS</b>SARS appears to be quickly infectious and potentially lethal among health care workers, characterized by acute onset and rapid progression, and mostly bilateral lung involvement on chest radiographs. Proper administration of glucocorticosteroids seems to be of some benefits. Antibiotics, human gamma-globulin, interferon-alpha, and antiviral drugs, although empirically, might be useful to shorten the clinical course.</p>
