AIM:To study the effect of neuregulin-1 ( NRG-1β) or captopril alone and their combination on myocardial cell apoptosis and related gene expression in rats with chronic heart failure .METHODS:Young male Sprague-Dawley rats were randomly divided into sham-operated group, heart failure group, NRG-1βgroup, captopril group and combined treatment group .The volume overloaded heart failure model in the rats was established by aortocaval fistula .The cardiac function was evaluated by determining the changes of hemodynamics and plasma BNP level .The apoptotic index ( AI) of myocardial cells was assayed by TUNEL .The protein levels of p-Akt, Bax and Bcl-2 in left ventricular tissue were detected by Western blot .RESULTS: The LVEDP, AI and the expression of Bax were significantly lower in NRG-1βgroup, captopril group and combined treatment group than those in heart failure group ( P<0.05 ) , while the values of ±dp/dtmax and the protein levels of p-Akt and Bcl-2 were significantly higher in NRG-1βgroup, captopril group and com-bined treatment group than those in heart failure group (P<0.05).The effect of combined treatment group was more signifi-cant ( P<0.05) than that in NRG-1βgroup and captopril group .CONCLUSION: Neuregulin-1βor captopril alone and the combination of them effectively improve the cardiac function and inhibit myocardial cell apoptosis in chronic heart failure rats.The therapeutic effect of combination of NRG-1βand captopril is better than that of NRG-1βor captopril alone .

Objective To analyze the clinical conditions and emergency treatment experiences of acute and chronic renal failure with hyperpotassemia. Methods Retrospective analyzed 542 clinical cases of supervening hyperpotassemia, which were treated by hemodialysis on 186 patients of renal failure with hyperpotassemia for 5 years. Results 540 cases clinical symptom was improved, serum potassium concentration was down to normal range and hyperpotassemia disappeared in electro cardiogram. 2 cases died after salvage. Rate of success was 99.6%. Conclusion Hemodialysis therapy is the most effective treatment to hyperpotassemia. Use bicarbonate with kalium pH indicator of 3.0～3.5mmol/L in dialysis is useful to lower hyperpotassemia, and safe also. In the early stage of hemodialysis, pure ultrafiltration dehydration treatment is not suitable. There is still danger of heartbeat stop deal to high kalium in the early stage of dialysis; emergency treatments should be standby all the time.

This paper presents a surgical optical navigation system with non-invasive, real-time, and positioning characteristics for open surgical procedure. The design was based on the principle of near-infrared fluorescence molecular imaging. The in vivo fluorescence excitation technology, multi-channel spectral camera technology and image fusion software technology were used. Visible and near-infrared light ring LED excitation source, multi-channel band pass filters, spectral camera 2 CCD optical sensor technology and computer systems were integrated, and, as a result, a new surgical optical navigation system was successfully developed. When the near-infrared fluorescence was injected, the system could display anatomical images of the tissue surface and near-infrared fluorescent functional images of surgical field simultaneously. The system can identify the lymphatic vessels, lymph node, tumor edge which doctor cannot find out with naked eye intra-operatively. Our research will guide effectively the surgeon to remove the tumor tissue to improve significantly the success rate of surgery. The technologies have obtained a national patent, with patent No. ZI. 2011 1 0292374. 1.
