ABSTRACT
Objective To investigate the clinical application value of strong ion gap(SIG)generated by the third generation equa-tion following pH and the anion gap(AG)in critically ill patients.Methods On the basis of the determination results of blood gas and blood biochemistry,the equation in the Stewart-Figge methodology was adopted to calculate SIG.Results (1)There were sta-tistically significant differences in K+ ,Na+ ,HCO3 - ,AG,pH,PO4 3 - ,ALB,SIG and Cr between the critical illness groups and the control group(P <0.05).(2)The SIG mean value ratio the death group to non-death group was 3.04,the difference was the big-gest,P <0.05,AG and Cr took the second place.Conclusion SIG as a new indicator in combination with other biochemical and blood gas indicators,such as the HCO3 - ,AG,pH,PO4 3 - ,Cr and lactic acid can reflect the situation of the acid-base disorders in critically ill patients and plays a strong indicative role in predicting the disease development trends.
ABSTRACT
In this paper is recommended a highly sensitive and reagent-safe method to determine plasma heamoglobin (FHb) in viscacha hemolytic test. The 2,4-dichlorophenol method (2,4-DCP) of Trinder reaction has been improved. The performance of 2,4-DCP is verified. The sensitivity of 2,4-DCP is 2.39 times that of phenol method. It is well used with run precision and day-to-day precision. The reaction color is stable. The reference value FHb is 1-36.7 mg/L. Sodium citric is an excellent anticoagulant liquid to keep erythrocyte. The 2,4-DCP method is neither carcinogenic nor poisonous;it is suitable for viscacha hemolytic test in clinical and biomedical engineering.

87%. CONCLUSIONS The surveillance of overexpressing AmpC ?-lactamases in cefoxitin-resistant Gram-negative bacillus must be enhanced.The therapy of infections caused by related bacillus should make imipenem and meropenem a chief choice.DHA-1,CMY-2 and CMY-22 AmpC enzymes are found in Fuzhou.
ABSTRACT
Objective To evaluate the early kindney injury by means of urinary protein/creatinine ratio(TPCR,200mg/g Cr)through group-discrimination in mellitus diabetes patients. Methods Qualitative analysis was carried out with urine 5~6 item indexes in 113 cases of diabetes mellitus ,61 cases of heallthy people and other 67 cases of diabetes mellitus patients. 2 groups were divided by means of urinary protein/creatinine ratio(TPCR,200mg/g Cr).Results In 113 cases of diabetes mellitus ,urine TPCR,mAlb,?2-MG,LAP and AFU of 38 cases in TPCR≥200mg/g Cr group were significantly higher than those of 75 cases in TPCR
ABSTRACT
Objective To Investigate the application value of strong ion gap(SIG),anion gap(AG)and other four indicators in the trauma disease.Methods Blood was taken from trauma patients admitted to hospital immediately,with the heparin anticoagulation,misce bene.Blood gas was measured.Creatinine(Cr),phosphorus and albumin(ALB)was measured simultaneously.Results Betwean traumatic group and control group,there was signifrcant difference in SIG,AG,potential HCO3-,and other 5 item(P4mmol/L.
ABSTRACT
Objective: To study the effect of chronic stress on spatial learning and memory and nitric oxide (NO) in hippocampus of the rats Method: Chronic stress model was established by electric-foot accompanied with noise Morris watermaze was used to observe spatial learning and memory abilities, contents of NO and activities of NOS in hippocampus were measured during the test Result: The spatial learning and memory of chronic stress rats were significantly decreased in Morris watermaze Contents of NO (3 87?0 47 nmol/mgpro) and NOS activity (102 64?13 33 pmol/mgpro/min) in hippocampus of the stress rats were significantly higher than that of normal rats (2 76?0 43 nmol/mgpro, 78 25?10 67 pmol/mgpro/min respectively) Conclusion: Chronic stress impairs spatial learning and memory abilities of rats, which may be related to the increase of NO in their hippocampus
