Objective To study the effect of lactate of differentconcentration on the action potential of ventricular papillary muscle cell (n=4) and contractile force (n=10).Method Using intracellular microelectrode technique and microtension depicting method.Result The Result showed the effect of lactated solution of a certain comcentration became obvious. After perfused with lactate solution of 4mmol/L,the vilocity maximum decreased significantly (p<0.05) showed the 4mmol/L lactate solution decreased the rate of depolarization: decreased the efficency of Na + channel; lactate solution decreased the contractile force of cardiac muscle. Conclusion The possible mechanism was: Ca+ influx and Na+ - H+ exchange were inhibited, resulted in the elevation of intracellular H+ concentration; through Na+-Ca2+ exchange, Ca2+ efflux decreased resulted in the intracellular Ca2+ decreased resulted in the intracellular Ca2+ overload.

Objective To do a longitudinal study of nursing undergraduates′ humanistic care ability in different period of clinical practice, and analyze its trend, aiming to provide reference about how to intervene to enhance the nursing undergraduates' humanistic care ability. Methods A total of 67 nursing undergraduates were investigated about their humanistic care ability with the Care Ability Inventory (Caring Ability Inventory, CAI) at the beginning, middle and end of the internship. Results The scores of seniors′ humanistic care ability at the beginning, middle and end of the internship were 194.97±22.93, 192.18±26.87, 187.24±22.15, and there was a statistically significant difference among the three time points (F=3.234, P<0.05), there was significant difference of the dimension of courage in different periods (F=7.511, P<0.01). Conclusions There is a downtrend of nursing undergraduates′humanistic care ability in different stages of clinical practice, and we suggest that nursing educators and administrators should consider the characteristics of different periods in the clinical practice, and then do a targeted training to foster nursing students′humanistic care ability.

It is to investigate the effect of two kinds of Houttuynia Cordata Injection on preventing and treating H1N1 influenza virus infection in mice. Pneumonia model was set up by intranasal infection of the normal and immunocompromised mice with influenza virus FM1 and PR8. The two injections were administered before and after the administration of virus, separately, and the lung index was observed. The results showed that the two preparations have obvious therapeutic effect on normal mice infected with influenza virus FM1 and PR8. And to FM1, the new injection's effect is better at small dosage. The results also showed that the two preparations have obvious prophylactic effect on immunodepressed mice infected with influenza virus FM1 and PR8. And to PR8, the old injection's effect is better at small dosage. Houttuynia Cordata Injection can improve the mice pneumonia caused by influenza virus H1N1 and decrease the lung index markedly. It has a remarkable preventive and therapeutic effect on H1N1 influenza virus in mice.

Objective To seek a optimization method for lung cancer planning with Helical TomoTherapy for reducing the low dose area of total lung.Methods CT images of thirty patients with unilateral lung cancer were selected.Seven plans (Groups A,B,C,D,E,F and G) were generated for each patient using an identical optimization procedure with the conditions that implemented contralateral lung with unblocked (control group),1/4 directional block,1/2 directional block,directional block,1/4 complete block,1/2 complete block and complete block,respectively.The benefits in different schemes of reducing the low dose area of normal lung tissue were estimated,in order to provide a reference treatment plan scheme in clinical.Results Groups B,C,D and E had less influence on the target than that of group A.And there were no statistical difference between the target dosimetric parameters.The median dose and average dose of group F were increased within 0.5 Gy.The conformal index of group G had great influence on the target.The low dose area of total lung were reduced effectively in Groups C,D,E,F and G,the average decrease of V5 and V10 was 8.06％-45.26％ and 6.21％-33.95％,respectively.The V20 decreased by 1.71％-3.78％ in directional block group,while V20 increased in complete block group (2.07％-5.07％).The single treatment time was increased by 8.51％-79.22％.Conclusions The results showed that the low dose area of total lung was higher for the plan without any block limitation.It could reduce the low dose area of total lung with directional block.We should lengthen the blocking arc of contralateral lung with directional block based on the fractional treatment time and the patient's physical condition.A certain arc of contralateral lung with complete block could effectively reduce low dose area.When complete block was used,it is suggested that the arc was no more than half of the contralateral lung.

Objective To explore the clinical efficacy and complications of the surgical treatment of sternal tumor resection and titanium mesh reconstruction.Methods From 2008 January to 2012 June,there were 8 cases of sternal tumor patients in our hospital,including 5 male and 3 female,with an average age of 50.4 (37-66) years old.The histological morphology included 2 cases of chondrosarcoma,1 case of osteosarcoma,2 cases of malignant fibrous histiocytoma,eosinophilic granuloma in 1 case,and 2 cases of sternal metastasis of breast cancer.Tumor invasion sites included the sternal manubrium in 3 cases,the body in 2 cases,and both in 3 cases.All patients had undergone preoperative puncture or incision biopsy.8 cases of sternal tumor patients were treated with sternal tumor resection and reconstruction of the thorax using titanium mesh.The clinical effect and complications were retrospectively analyzed.Results All patients were followed up for 9 months to 4 years.The operations went well in all cases,with no intraoperative crisis or operative death.Deep wound hematoma occurred in 1 patient 1 week postoperatively,who healed 2 weeks after drainage and debridement.There was no abnormal breathing,subcutaneous emphysema,pneumothorax,infection or other complications in other cases.1 case of malignant fibrous histiocytoma died of lung metastasis at 9 months follow-up,and 1 died of liver metastasis at 14 months,while other patients got no tumor recurrence,with good thoracic shape,free breathing,no titanium mesh loosening,dyspnea,chest tightness,pain,or abnormal respiratory discomfort during follow-up period.The chest radiograph showed no chest deformity,no loosening or fracture of the fixation device.Conclusion Sternal tumor resection and reconstruction with titanium mesh has the advantages of good shaping effect,fewer complications,and simple operation,showing that titanium mesh is an ideal material for the reconstruction of sternum.
