Objective To evaluate the association between C-reactive protein (CRP) blood levels and specific survival time of non-small cell lung cancer (NSCLC) patients treated with chemotherapy.Methods Data from 96 advanced (stage ⅢB/Ⅳ) NSCLC patients were analyzed.All patients were divided into two groups based on the enrolled time as follows the initial treatment group (48 cases) and retreatment group (48 cases).According to 0.6 mg/L and 7.3 mg/L of CRP which were the 1/3 and 2/3 of CRP concentrations,respectively,the 96 patients were divided into low,intermediate and high groups.Kaplan-Meier and Cox proportional-hazard models were used to evaluate the relationship between the CRP level and survival time.Results After adjusting for age,sex,smoking history,histological type and stage of lung cancer,a significant relationship between CRP and survival time was observed (P < 0.05).Such significant differences of survival time were also observed in both of the adenocarcinoma (P < 0.001) and squamous with poorly differentiated (P =0.032) subtypes.On stratification analysis by chemotherapy status,the circulating CRP level in retreatment group was correlated well with survival time (P < 0.001).However,the influence of circulating CRP levels on survival time in initial group did not reach statistical significance (P =0.296).For all patients,the hazard ratio with high CRP levels for NSCLC-specific survival was 1.15 (95 % CI 0.82-1.61) compared with that of low CRP levels.The hazard ratio for the initial treatment group and retreatment group were 0.52 (95 % CI 0.16-1.74) and 1.77 (95 % CI 0.73-4.26),respectively.Patients with high circulating CRP level also responded poorly to chemotherapy.Conclusion A high level of circulating CRP is associated with an inferior response and survival outcome in NSCLC patients treated with chemotherapy.

10.Arterial baroreflex function and left ventricular hypertrophy
Academic Journal of Second Military Medical University 2004;25(4):448-448
It is well known that the arterial baroreflex(ABR)plays a key role in the regulation of heart rate and stabilization of blood pressure.Currently,it appears that ABR dysfunction is involved in the pathophysiology of cardiovascular disease states.Since the mid-1990s,a number of studies have been carried out in our laboratory to explore the pathological significance of ABR function in cardiovascular damage.This minireview summarizes our research work on the topic of ABR and left ventricular hypertrophy(LVH).On the basis of discussion concerning the importance of ABR dysfunction in hypertensive LVH and sinoaortic denervation-induced LVH,we advance a new strategy for reversal of LVH,that is,restoration of impaired ABR function.We tested this hypothesis in animal models with ABR deficiency.It was found that improvement of impaird ABR function with long-term treatment of ketanserin or candesartan was accompanied by reversal of LVH.The preliminary results indicate that it is feasible to target ABR for treatment of LVH.
