Safety evaluation of Parecoxib Sodium for Injection / 药物评价研究

Objective To evaluate the safety of Parecoxib Sodium for Injection.Methods Systemic active anaphylaxis test:Guinea pigs were injected respectively with Parecoxib Sodium for Injection (test sample,20 mg/mL),primary control,sodium chloride injection or human serum albumin,once every other day,continuously for three times.After 14 and 21 d from the end time of sensitization,to stimulation and to observe whether allergic reactions occurred within 30 mins.Passive cutaneous anaphylaxis test:Guinea pigs were received 0.1 mL antiserum injection for inducing passive sensitization,after 24 h of that we stimulated the guinea pigs,and the guinea pigs were sacrificed after 30 mins to examine the diameter of blue spots.Blood vessel irritation test:After continuous ear Ⅳ test sample for 5 d,HE staining was performed at the end of the administration and recovery period,and the stimulation of the blood vessel at the site of injection was observed.Hemolysis or agglutination of Parecoxib Sodium for Injection was examined by in vitro methods.Results Under the dosage of 20 mg/mL,guinea pigs showed no systemic allergy and passive skin allergy,and no hemolysis,agglutination,and irritation of vascular was observed.Conclusion Under the present experimental conditions,20 mg/mL Parecoxib Sodium for Injection shows no obvious allergic reactions,irritation and hemolysis,is safe.

Clinical efficacy of cefoperazone and Shubatan in the treatment of severe acute infection / 中国生化药物杂志

Objective To investigate and analyze the clinical efficacy of cefoperazone and Shubatan in the treatment of severe infection in emergency department. Methods 100 cases of severe infection were randomly divided into control group and experimental group, with 50 patients in each group. The control group received routine treatment, and the experimental group was treated with cefoperazone and Shubatan on this basis. Pay close attention to the related vital signs change of the experimental group and the control group, the relevant clinical indicators of the two groups of patients were compared and analyzed. Results After the corresponding treatment, the bacteria removal rate of the experimental group was 90.00%, significantly higher thant 60.00 % of the control group (P<0.05). The effective rate of the experimental group was 90.00%, which was significantly higher than that of the control group (74.00%), which was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups. After treatment, the total score of quality of life in the experimental group was (75.2±11.2) points, and the total score of QOL in the control group was (64.2±9.3) points, which was statistically significant (P<0.05). Conclusion The clinical efficacy of cefoperazone and Shubatan in the treatment of emergency severe infection is satisfactory. It can significantly improve the clinical symptoms and improve the quality of life in patients with severe acute respiratory infection.

Postmortem distribution of tetrodotoxin in tissues and body fluids of guinea pigs / 法医学杂志

OBJECTIVE@#To investigate the postmortem distribution of tetrodotoxin in tissues and body fluids of guinea pig, and to provide method and evidence for forensic identification and clinical diagnosis and treatment.@*METHODS@#Guinea pigs were intragastric administrated with 100, 50, 15 microg/kg tetrodotoxin, respectively. The poisoning symptoms were observed. The samples of heart, liver, spleen, lung, kidney, brain, stomach, intestines, bile, heart blood and urine were collected. The concentrations of tetrodotoxin in tissues and body fluids were measured with liquid chromatography-tandem mass spectrometry (LC-MS/MS).@*RESULTS@#After administrated with tetrodotoxin, all guinea pigs came out poisoning signs including tachypnea, weary and dead finally. Tetrodotoxin concentrations in lung, stomach, intestines and urine were higher, followed by blood, heart and brain. The concentration in bile was the lowest.@*CONCLUSION@#Postmortem distribution of tetrodotoxin in guinea pig is uneven. The concentration in the lung, stomach, intestines, urine and heart blood are higher, those tissues could be used for diagnosis of tetrodotoxin poisoning.

Observation of gastric intubation with zebra- guidewire under the induction of anesthesia with sevoflurane / 中国实用护理杂志

ObjectiveTo investigate the practicability of gastric intubation with zebra-guidewire under the induction of anesthesia with sevoflurane (zebra-guidewire was the obsolete guide wire in percutaneous nephrolithotomy in urology surgery). MethodsThe patients who needed gastric intubation were randomized into the experimental group and the control group with 20 patients in each group.the experimental group received gastric intubation with zebra- guidewire under the induction of anesthesia with sevoflurane.In the control group,the gastric tubes were catheterized with routine method.The physiological indices changes,incidence rate of adverse reaction and success rate of one-time catheterization and average time of catheterization per patient were compared between the two groups. ResultsIn patients of the experimental group,the blood pressure,heart rate before and during the intubation did not fluctuate evidently,but in the control group the results were the opposite.In the experimental group the incidence rate of adverse reaction,success rate of one-time catheterization and average time of catheterization per patient were superior to the control group. ConclusionsGastric intubation under the induction of anesthesia with sevoflurane was a painless way of gastric intubation.Gastric intubation with zebra-guidewire under anesthesia state was simple and fast.

Determination of TTX in biological samples by LC-MS/MS / 法医学杂志

OBJECTIVE@#To propose a method for determination of tetrodotoxin (TTX) in human blood, urine and liver by liquid chromatography with tandem mass spectrometry (LC-MS/MS).@*METHODS@#Solid phase extraction is used after the samples are precipitated, then the samples will be analyzed by LC-MS/MS.@*RESULTS@#The limits of detection were 2 ng/mL in blood and urine and 4 ng/g in liver for TIX respectively, the linear correlation coefficients were not less than 0.9973, both of the intra-day and inter-day precisions were less than 12.80%, the recoveries for all kinds of specimens were more than 47.2%.@*CONCLUSION@#This method is efficient, sensitive and accurate and was successfully validated for implementation in forensic toxicological analysis.
