Journal of Third Military Medical University 2003;0(17):-
Objective To investigate the protective effect of Ca 2+ channal blocker(Verapamil)on the testis following testicular torsion in rats.Methods Forty healthy male Sprague-Danley rats were randomly divided equally into five groups:group A(sham operation),group B1(the left testis underwent 720? positive torsion,2 h later detorsion was performed),group B2(the process as group B1 except at 30 min before detorsion,intraperitoneal injection of physiological saline was performed),group B3(the process as group B1 except at 30 min before detorsion,intraperitoneal injection of 2 mg/kg Verapami was performed),group B4(the left testis underwent 720? positive torsion,and 2 h later the left testis was excised).Five days after operation,the bilateral testes(the right testis in group B4)were extracted and nitric oxide(NO),nitric oxide synthase activity(NOS),total antioxygen capacity(T-AOC)were measured.Results After detorsion,NO and NOS activity increased greatly,T-AOC decreased significantly in bilateral testes,but more obvious in the torsive testis;Verapamil could inhibit the changes.Conclusion The excessive production of NO and the decreased T-AOC may be the main causes of the contralateral testicular injury after unilateral testicular torsion.Verapamil can reduce the testicular injury in bilateral testes after testicular torsion/detorsion in rats.The resection of the torsive testis has protective effect on the contralateral one.

Objective To investigate the influence of continuous veno-venous hemofiltration (CVVH) on cardiac output (CO) value and parameters of hemodynamics monitored by transpulmonary thermodilution technique in critical patients. Methods A prospective cohort study was conduced. Sixty-two critical patients admitted to intensive care unit (ICU) of Zunyi Medical College Affiliated Hospital from January 2011 to October 2015 were enrolled. All of the patients received CVVH through femoral vein puncture catheter. The CO value was monitored before CVVH operation, immediately after CVVH operation (8 ℃ normal saline was injected immediately after the output of blood from the arterial end), 5 minutes after operation, the time at the sudden interruption (press pause key after 10 minutes of operation) and resumed immediately, 15 minutes and 30 minutes after operation by pulse-indicated continuous cardiac output (PiCCO) with transpulmonary thermodilution method. The changes in heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and blood temperature were observed at all time points. Results From CVVH before start to 5 minutes thereafter, CO values were not significantly changed in patients, fluctuating in 6.96 (7.33, 8.67)-6.98 (6.43, 7.45) L/min. When CVVH was suddenly interrupted, CO value was immediately increased to the peak 8.04 (7.36, 8.77) L/min, which showed statistically significant difference as compared with other time points (all P < 0.01). Immediately after the CVVH recovery from interruption, the CO value dropped to 4.71 (4.14, 7.26) L/min, and it was significantly lower than those at other time points (all P < 0.01). With the CVVH recovery, the patients' CO value was gradually restored to the stable operation ahead of interruption [4.71 (4.14, 7.26)-6.85 (6.08, 7.26) L/min]. During CO monitoring, HR, MAP, CVP and blood temperature of the patients were at the same level, and no significant changes were founded. Conclusions CVVH interruption of immediate PiCCO monitoring CO value were significantly increased, immediately after the CVVH recovery the CO value were significantly reduced, and the normal operation of CVVH did not affect the CO value monitoring. Hemodynamics and blood temperature of all patients were stable during CVVH.

The difference of the level of plasma VEGF of experimental group and control group after treatment was statistically significant(t =2.793,P <0.05). The level of plasma VEGFR [(2490.75+1695.9) pg/ml, (2322.78+1105.87) pg/ml] of experimental group and control group before treatment was statistically significant (t =2.914, t =2.783, P <0.01) compared with healthy group [(1134.98+378.45) pg/ml] respectively. The level of plasma VEGFR of those groups after treatment [(1359.71± 390.24) pg/ml, (1753.89±337.04) pg/ml] was statistically significant(t =2.572, t =2.447, P <0.05) compared with healthy group respectively. The difference of the level of plasma VEGFR of experimental group and control group before treatment was not statistically significant (t =1.276, P >0.05). The difference of the level of plasma VEGFR of experimental group and control group after treatment was statistically significant (t = 2.486, P <0.05). The level of plasma bFGF [(2.43±0.27) ng/ml, (2.41±0.33) ng/ml] of experimental group and control group before treatment was statistically significant(t =4.982, t =4.171, P <0.05) compared with healthy group (1.83±0.44) ng/ml respectively; the level of plasma bFGF of those groups after treatment [(2.09±0.17) ng/ml,(2.11±0.31) ng/ml] was statistically significant (t =3.011, t =2.773, P <0.05) compared with healthy group respectively. The difference of the level of plasma bFGF of experimental group and control group before treatment was not statistically significant (t =0.953, P >0.05). The difference of the level of plasma bFGF of experimental group and control group after treatment was not statistically significant (t =1.282, P >0.05).Conclusion The remission rate could be improved by thalidomide combined with chemotherapy in acute leukemia, which could be an effective treatment by anti-angiogenesis and inhibiting the growth and infiltration of acute leukemia cells.
