Objective To investigate the clinical, electrophysiological and pathological features of critical illness polyneuropathy and myopathy (CIPNM). Methods The clinical outcomes, electromyogram Results as well as pathological features in nerves and muscles of 3 patients with CIPNM were investigated and analyzed. Results 3 patients were all provided with assisted respiration after tracheal intubation. 7~10 d after intubation, all the patients emerged muscle strength and tendon reflexes of extremities weakening; while 14 days after that, 2 patients appeared amyotrophy of extremities. Electromyogram showed that the conduction of many motor and sensory nerves for extremities decreased, while the amplitude of compound muscle action potential (CMAP) of part of motor nerves decreased. Biopsy for nerves revealed decreased medullated nerve fibers and regeneration phenomenon of auxiliary fibers; while that for muscles showed neuralgic damage and myopathy-like changes. Conclusion CIPNM can complicate after tracheal intubation. The electrophysiological and pathological examinations for nerves and muscles can be helpful for the diagnosis.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.
METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.
RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.
CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.
