Objective: To evaluate the effects of treatment of integrative Chinese and Western medicine (ICWM) on arterial oxygen saturation (SaO2) in patients with severe acute respiratory syndrome (SARS).Methods:The non-randomized, controlled trial was conducted on 447 SARS patients treated synchronously with western conventional treatment (WM group,n= 171) alone and ICWM (ICWM group,n= 276). The changes of the cases with normal level (≥95%) or abnormal level (<95%) SaO2were observed dynamically.Results: In the 3rd-14th day of the therapeutic course, the percentage of patients with normal SaO2 in the ICWM group was higher than that in the WM group (OR = 0. 5178,P= 0.0038), and this tendency was more evident in patients of the severe type (OR = 0.18,P= 0.0001). However, the statistical significance of difference was only shown in patients for whom the ICWM treatment started in the early period after the onset (<-7 days after it, OR = 0.3803,P= 0.006), but not shown in those who received ICWM treatment later in the mid-late period of SARS (P>0.05).Conclusion: ICWM treatment, particularly when it is used for intervention in the early stage, is beneficial for maintaining normal SaO2in SARS patients.

Oscillator strength f-values for L-shell transitions in highly ionized sulfur are studied by the beam–foil technique at the HI-13 tandem accelerator in China Institute of Atomic Energy. The lifetimes of the upper levels 2s2p ¹P^o₁, 2p^{2 1}S₀, 2p^{2 3}P₁, 2p^{2 3}P₂, 2p^{2 3}P₀ of Be-like sulfur are measured to be 129±4, 81±5, 165±7, 159±8, 176±11 ps. By using the measured lifetimes, the f-values are calculated to be 0.074, 0.082, 0.060, 0.066, 0.229, 0.056, 0.083, 0.089, 0.028 for the transitions 2s²2p^{2 3}P₁–2s2p^{3 3}P^o₁, 2s²2p ²P^o_3/2–2s2p^{2 2}P_1/2, 2s2p^{2 4}P_3/2–2p^{3 4}S^o_3/2, 2s²2p ²P^o_1/2–2s2p^{2 2}D_3/2, 2s^{2 1}S₀–2s2p ¹P^o₁, 2s2p¹P^o₁–2p^{2 1}S₀, 2s2p³P^o₀–2p^{2 3}P₁, 2s2p ³P^o₂–2p^{2 3}P₂ and 2s2p ³P^o₁–2p^{2 3}P₀. Most of the experimental results are in agreement with theoretical studies, but differ slightly from the previous experimental data.
