ABSTRACT

Objective To study the effect of ganoderma lucidum polysaccharides on T cell subsets and AQP1, AQP3 expression of bladder cancer T24 cell line bearing mice.Methods 60 BALB/C nude mice were selection as experimental animals, bladder tumor bearing animal models were made by bladder cancer T24 cells subcutaneous injection, and were randomly divided into control group, cisplatin group, ganoderma lucidum polysaccharides and cisplatin group, cisplatin group given 25 mg/kgcisplatin intraperitoneal injection, cisplatin combined ganoderma lucidum polysaccharide group given 200 mg/kg ganoderma lucidum polysaccharide lavage, 25 mg/kg cisplatin intraperitoneal injection, the control group given quite a volume normal saline lavage.Then tumor volume and weight, peripheral blood T cell subsets and AQP1, AQP3, Caspase-3, Bax mRNA content in tumor tissue were determined.Results Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide tumor volume and mass were significantly lower than the control group (P<0.05), cisplatin and ganoderma lucidum polysaccharide tumor volume and mass were significantly lower than that cisplatin group ( P<0.05 ); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharides group CD4 + T cells, CD8 +T cells , CD4 +/CD8 + were significantly higher than that of control group (P<0.05), cisplatin combined ganoderma lucidum polysaccharide group CD4 +T cells, CD4 +/CD8 +were significantly higher than that of cisplatin group (P<0.05); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide group mices tumor tissues Bax, Caspase 3 mRNA content were significantly lower than the control group (P<0.05), cisplatin combined ganoderma lucidum polysaccharide group Bax,caspase 3 mRNA content were significantly lower than that of cisplatin group (P<0.05); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide group mice tumor tissue AQP1, AQP3 mRNA content were significantly lower than the control group (P<0.05); Cisplatin combined ganoderma lucidum polysaccharide group AQP1, AQP3 mRNA content were significantly lower than cisplatin group (P<0.05 ). Conclusion ganoderma lucidum polysaccharide can inhibit tumor growth and enhance cellular immune function of bladder cancer T24 cell line bearing mice, and adjust the expression of pro-apoptotic genes, AQP1 and AQP3.

ABSTRACT

It is an important way for interns to evaluate and test quality of teaching and results of practice by means of clinical check.Applying dynamic simulation of anesthesia in our university,we statistically analyzed check results for interns of anesthesia specialty from 1996 to 2003 to invest present problems,aiming at perfecting clinical practice and teaching work of anesthesia specialty and favoring to cultivating talents with high diathesis.

ABSTRACT

The effects of continuous occlusion of thoracic or abdominal aorta (OTA or OAA) via intra-aortic balloon inflation on coronary perfusion pressure (CPP) were observed in 12 dogs after 10 min of cardiac fibrillation in comparison with those of different doses of epinephrine (0.02~0.14 mg/kg). The results showed that OTA could not increase CPP. However, during 30 min of cardiopu-Imonary resuscitation(CPR), every 3 min of OAA was followed by markedly increased CPP, 067 ~ 12kPa higher than the value in balloon deflation peritxl right before(P

ABSTRACT

Objective:To discuss the early diagnosis of malignant hyperthermia(MH) and its treatment regimen without dantrolene.Methods: A patient of American Society of Anesthesiologist class Ⅰhad sudden muscle spasms and masseter muscle spasm during induction of anesthesia for idiopathic scoliosis surgery,and was diagnosed as having MH.Without using dantrolene,the patient was treated promptly with removal of inducement,control of temperature,adequate oxygen supply,maintaining of pH,water and electrolyte balance,and protection of renal function.The dynamic changes of the myoglobin in the blood and urine,serum creatine kinase,the blood gas indicators,and EtCO2,together with the pathological changes of the quadriceps were observed.Our experience on diagnosis and treatment was summarized.Results: The patient fully recovered and was discharged without any complications.The myoglobin in the blood and urine,serum creatine kinase and its isoenzyme increased rapidly and reached the peak one hour after MH,and maintained for about ten hours,then returned gradually to normal level about five days later.The temperature and EtCO2 increased immediately after development of MH,arterial blood gas quickly showed hypercapnic acidosis,but pH maintained normal or partial alkali during the treatment due to sodium bicarbonate administration;the alkali maintained obviously higher.Some quadriceps muscle cell had vacuolar degeneration and lysis.Conclusion: Non-ventilation induced increase of EtCO2 is a reliable indicator for early diagnosis of MH.Anesthetics,such as succinylcholine,should be avoided in patients at high risk of MH,and EtCO2 should be monitored.Once MH is diagnosed,dantrolene is the first choice.When without dantrolene,satisfactory outcome can be achieved through early diagnosis,timely removal of incentives,control of temperature,adequate oxygen supply,maintaining of stable internal environment,control of arrhythmia and protection of renal function.
