Objective To explore the short and long-term effect of cardiopulmonary resuscitation (CPR) training for agricultural residence registration population with the language education and practice education,in order to establish a more effective method of first-aid training for agriculture population.Methods 989 agricultural residence registration people were divided into group A (721 people)and group B (268 people) randomly.Group A received CPR training with language education and group B adopted practice education.On the time before and after training immediatelythe 3rd and 6th month after training,we checked the training results and analyzed the data with statistical methods.Results The short- term effect of two methods was satisfying (accuracy more then 90％ ) and without statistical significance.The effect of group B was better than group A in the 3rd and 6th month after training.Two groups showed higher forgetting rate and some accuracy were less than 50％.Conclusions Agriculture population is in urgent need of first-aid.It may be a more effective method of first-aid training for agriculture population to transform gradually from language education to practice education.At the same time,we may use 4 hours as CPR practice education training time and 6 months as re-training period.

OBJECTIVE:To study the hypoglycemic effects of Insulin self-microemulsion for parenteral administration on mod-el rats with type 1 diabetes in vivo. METHODS:Rats were treated with streptozotocin(50 mg/kg)to reproduce model with type 1 diabetes,ip. The model rats were randomly divided into model group (normal saline),positive control group (Insulin injection 2.25 u/kg) and self-microemulsion low,medium and high dose groups (Insulin self-microemulsion 4.5,9 and 18 u/kg);and 10 normal rats were involved in sham-operation group (normal saline). Anesthesia and operation were conducted for all rats. Positive control group was administrated,ip;other rats were parenterally administrated. The blood glucose levels in groups were detected be-fore and after 15-600 min administration. Glucose tolerance test was conducted for the rats in normal control group,model group without glucose,model group with glucose and microemulsion group (Insulin self-microemulsion 9 u/kg). All group were given glucose except model group without glucose. RESULTS:Compared with sham-operation group,the blood glucose levels in model group within 0-240 min were increased,with significant difference(P<0.05). Compared with model group,there was hypoglyce-mic trend in positive control group after 15 min,the blood glucose levels within 30-480 min were decreased,the hypoglycemic peak was 36%,and the peak time was 30 min;there was also hypoglycemic trend in microemulsion low,medium and high dose groups after 30 min,the blood glucose levels within 45-360 min were decreased,hypoglycemic peak was 18%-21%,and the peak time was 90-120 min,with significant differences (P<0.01 or P<0.05). All rats had glucose absorption peak except for model group without glucose in glucose tolerance test,and glucose of rats in microemulsion group reached its peak and then quickly de-creased. CONCLUSIONS:Insulin self-microemulsion can obviously reduce the blood glucose of model rats with type 1 diabetes.

Objective To establish a spontaneous abortion rat model for a syndrome in traditional chinese medicine, kidney deficiency, and observe the changes of physiological indicators and related cytokine expression in the model. Methods 40 female and 20 male rats were used in this study. The female and male rats were mated (mating ratio 2:1). The day of vaginal smear with a large number of sperm was considered as the first day of pregnancy. The rats were randomly divided into control group and model group. The model group received 450 mg/kg hydroxyurea every day. Mifepristone was given on the eighth day in a dose of 3.75 mg/kg. The diet amount, the diameter index of kidney, ovary and embryos were analyzed. The mRNA expression of Th1/Th2 cytokine was detected by RT-PCR, and the expression of co-stimulating factors CD80, CD86, CD28, CTLA-4 were determined by flow cytometry.Results Comparing the model group with control group on the eighth day, there were significant differences between the model and control groups in quantity of food and water intake, and weight increase (P<0.05), and also in the embryonic diameter index, average of abortion rate, Th1/Th2 type cytokines, co-stimulating factor CD80, CD86, CD28, and CTLA-4 (P<0.05). Conclusion A rat model of spontaneous abortion due to kidney deficiency can be successfully established with hydroxyurea and mifepristone. The high expression of Th1 (TNF-α, IFN-γ) may cause abortion and be harmful to pregnancy. Th2 type (IL-4, IL-10) may facilitate pregnancy. The expression co-stimulating factor CD80, CD86, CD28, CTLA-4 may be relevant to the spontaneous abortion.

Objective To study the possible mechanisms by which repetitive transcranial magnetic stimulation (rTMS) pretreatment antagonizes seizures induced by lithium chloride-pilocarpine and any correlation with antiapoptosis in hippocampal CA1 neurons.Methods Thirty rats were randomly divided into a control group, a sham stimulation group and an rTMS pretreatment group. The rTMS pretreatment group was pretreated on 7 consecutive days with low-frequency rTMS (0.5 Hz, 75％ of threshold intensity, 20 times/bundle, and 5 bundles/d), while the sham-stimulation group was sham-stimulated with a similar sound. Lithium chloride-pilocarpine ( LPC ) was used to induce a model epileptic state.Epileptic stroke latency and severity were recorded ; neuronal morphology was observed using hematoxylin and eosin (HE) staining; mean positive-reactive cell number and mean optical density and absorbance of B cell lymphoma/leukemia gene-2 (Bcl-2) were recorded, and Fas and Caspase-3 protein in the hippocampal CA1 region were observed with immunohistochemistry.Results Compared with the sham stimulation group, epileptic latency in the rTMS pretreatment group was significantly longer. Seizures in the rTMS pretreatment group were less severe, and a number of degenerated neurons were observed to be apoptotic. Bcl-2 protein expression increased at each time point, but Fas and Caspase-3 protein expression decreased.Conclusions rTMS pretreatment has an anti-epilepsy effect. The possible neuronal protection might be produced by regulating the expression of Bcl-2, Fas and Caspase-3 protein in the hippocampus.

[ABSTRACT]OBJECTIVETo investigate the relationship between upper airway MRI parameters and the severity of patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Then the values of upper airway MRI parameters in waking state were assessed.METHODS The MRI upper airway parameters of 37 OSAHS patients and 18 nonsnoring normal subjects were measured and compared. Then data analysis were carried out to find out significant correlations between the MRI upper airway parameters and the severity of patients (the apnea hypopnea index, AHI; the lowest oxygen saturation, LSaO2; the oxygen desaturation index, ODI) with OSAHS.RESULTSThe correlation between cross-sectional areas and left-right diameter in the narrowest retropalatal region, the thickness of lateral pharyngeal wall, the length of the tongue, the length and thickness of the soft palate and the cross-sectional areas of the soft palate on midsagittal planes and severity of OSAHS were found (P<0.05).CONCLUSIONThe MRI upper airway parameters can be used in evaluating the severity of OSAHS in some ways, locating the obstruction sites and choosing the best treatment planning.
