With the introduction and wide acceptance of the Glasgow coma scale, some progress was made in 1980s. Various types of coma scale were offered from different centers of the world for assessing coma and impaired consciousness. The existing coma scales may be divided into two main categories: (1) multi-dimensional scale, e.g., Glasgow coma scale (GCS), Glasgow-Liege coma scale (G-LCS), Maryland coma scale (MCS); and (2) uni-dimensional scale, e.g., Edinburgh-2 coma scale (E2CS). ⋯ On the basis of comparison between two main categories of coma scale and considering the shortcomings of E2CS, a modified uni-dimensional ordinal coma scale called "Chengdu-1 Coma scale" (C1CS) was proposed and applied for evaluating the depth of coma and for prognosticating the patients' outcome. This study was based on 98 acutely head-injured patients treated in the Neurosurgical department of 1st Affiliated Hospital of WCUMS, from October 1983 through May 1984. The follow-up results showed that a good correlation was observed between the score of C1CS and the outcome scale score (Glasgow outcome scale, GOS) of the patients.

[The mechanism and clinical significance of decreased anion gap in patients with COPD and acid-base imbalance].
The blood-gas and electrolytes of 427 blood samples from patients with COPD and acid-base imbalance were analysed. The results showed that 14 types of acid-base imbalance were present in patients with COPD and the anion gap decreased in 8 types of acid-base imbalance, especially in respiratory acidosis, metabolic alkalosis and coexistence of both. The anion gap in respiratory acidosis and metabolic alkalosis were 0.8 +/- 6.6mmol/L and 2.1 +/- 7.3mmol/L, respectively. ⋯ The anion gap decreased owing to the diminution of unmeasured anion. Clinically, the criterion for judging metabolic acidosis with increased anion gap is a value of anion gap over 16 mmol/L. But in case respiratory acidosis (or metabolic alkalosis) and metabolic acidosis coexist in a patient, the anion gap for judging metabolic acidosis should be decreased appropriately.
