Objective: To observe the clinical effects of pediatric tuina plus Chinese medicine for exogenous fever in children. Methods: A total of 150 children withexogenous fever were randomly divided based on the random digital table into a control group (75 cases) and a treatment group (75 cases). The control group was treated with oral Xiao'er Chaigui Tuire Keli (<1 year old, 0.5 bag/time; 1-3 years old, 1 bag/time; 4-6 years old, 1.5 bags/time), 4 times/day. The treatment group was treated with pediatric tuina plus the intervention of the control group. The amount and usage of Chinese medicine were the same as those of the control group; tuina was conducted 1 time/day. The clinical effects and adverse reactions were observed after 3 d of treatment in both groups. The recurrence was observed within 7 d after the end of treatment. Results: The total effective rate was 92.0％ in the treatment group and 81.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups after treatment. The recurrence rate was 1.5％ in the treatment group and 13.1％ in the control group. The difference in the recurrence rate between the two groups was statistically significant (P<0.05). Conclusion: Pediatric tuina plus Chinese medicine is effective in treating children with exogenous fever.

Objective To study the clinical nursing significance of ECG monitor in primary PCI for AMI patients and the relation of changes in ECG and the reperfusion of infarction related artery.Methods Regressional analysis was made in ECG changes including different types of arrthymia,degree of ST segment regression,and their relation between the reperfusion of infarction related artery before and after interventional therapy in AMI patients.Results In 468 AMI patients,142 patients had ventricular arrhythmia before therapy.After interrentional therapy,285 patients were co-morbid with accelerated ventricular tachycardia,203 patients with transient ventricular tachycardia or R-on-T phenomenon,62 patients with ventricular fibrillation and received asynchronous electriacal cardioversion.Twenty four patients had new onsent of Ⅱ-Ⅲ degree atrio-ventricular block and 45 patients had bradycardia or sinus arrest.The atrio-ventricular blook in 10 patients before PCI disappeared after the operation.There are 301 patients with apparent ST segment regression(ST segment regressed ≥50%,57 patients with partial ST segment regression,and 29 patients without ST segment changes.Conclusion Arrhythmias always accompanied with IRA reperfusion.Careful monitoring of ECG is essential for patients' safety after AMI.Obvious ST segment is observed in sufficient IRA reperfusion.However,poor regression of ST segment as well as haemodynamics disorder and cardiogenic shock is observed in patients with poor reperfusion or subacute occlusion of IRA.

By using cup culture, influence of different strains (ammonium-resistant N2-fixing type, wild type, none N2-fixing type) of Klebsiella oxytoca on the growth of rice seedling was compared. It was discovered that ammonium-resistant N2 -fixing bacteria could excrete some plant growth promoting substance, which could be adsorbed by cation resin. It' s activity wouldn't be affected at 80℃. At optimal concentration, the weight of rice root and seedling were increased by

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

The circuit of a monitoring system for respiratory mechanical parameters is designed based on the detection of respiratory flow and pressure. Breaking through the restrictions of traditional methods that can only monitor respiratory rate, this design is able to monitor more than 10 respiratory parameters simultaneously and thus provides a good technical support for improving the properties of homemade monitors.

OBJECTIVE: To observe the effects of intermedin preconditioning on hypoxic injury in rat's cardiac myocytes and to provide the hypothetical mechanism of sudden cardiac death in the field of forensic pathology. METHODS: The H9c2 cultured rat cardiac myocytes were randomly divided into control group, hypoxia group and IMD group. The myocardial cell viability, cellular ultrastructure, intracellular calcium concentration and apoptosis rate were determined by MTT assay, transmission electron microscopy, laser scanning confocal microscope and flow cytometry, respectively. RESULTS: Compared with the control group, cell viability obviously decreased with inner ultrastructure injury in the hypoxia group (P<0.05), while cell viability significantly increased in the IMD group by reducing the hypoxia injury of cardiac myocytes (P<0.05). Compared with the control group, [Ca2+]i (fluorescence intensity) and apoptosis rate significantly increased in the hypoxia group, but decreased in the IMD group (P<0.05). CONCLUSION IMD increases the cell survival rate and decreases the cell apoptosis inhibited by intracellular calcium overload from hypoxia. This finding may reveal the mechanism of protective effects of myocardial hypoxia, and provide a scientific basis for the identification sudden cardiac death.
