OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.
METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.
RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).
CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

AIM To investigate the effects of serine/threonine protein phosphatases in regulation of cell signal transduction on voltage-gated potassium and calcium channels in cultured rat trigeminal ganglion (TRG) neurons. METHODS Whole-cell patch clamp technique was used to record the potassium and calcium currents from adult rat TRG neurons before and after perfusion of okadaic acid, a potent inhibitor of the serine/threonine protein phosphatases 1 and 2A. RESULTS Okadaic acid 1 μmol·L-1 inhibited transient outwards potassium currents (IA) by 28.6%, increased delay rectified potassium currents (IK) and calcium currents (ICa) by 22.7% and 20.0%, respectively. okadaic acid 1 μmol·L-1 produced significant hyperpolarizing shifts in the conductance-voltage (G-V) curves and inactivation curves of IA , also produced significant hyperpolarizing shifts in the G-V curves of IK, while it had no effect on the activation and inactivation kinetics of ICa. CONCLUSION Serine/threonine protein phosphatases 1 and 2A may be involved in the modulation of voltage-gated potassium and calcium channels on rat TRG neurons. In addition, voltage-gated potassium and calcium channels show different dependence on the dephosphorylation reactions of PP1 and PP2A phosphatases.
