Objective To discuss the method to increase the success rate of stomach tube insertion for patients with indwelling nasotracheal tube in order to shorten the time of insertion operation and reduce the discomfort of patients.Methods Seventy patients with nasotracheal tube were randomly divided into the observation group(38 cases)and the control group(32 cases).When the operator for the observation group inserted stomach tube to 18～22 centimeters deep,the nurse pumped the gas out from the tracheal catheter aerocyst.After the stomach tube reached stomach the tracheal catheter aerocyst was aerified again.The control group did not release the gas from tracheal catheter aerocyst when inserting the stomach tube.The first intubation success rate and time needed for intubation were compared between the two groups.Results The first intubation success rate of the observation group was higher than that of the control group(P＜0.05).While the time needed for intubation was shorter than that of the control group(P＜0.01).Conclusions Method used by the observation group not only increased the first intubation success rate,but also shortened time needed for intubation.This method can alleviated pain of patients and worth applying widely in clinic.

Objective To explore the importance of diabetic education and hypoglycemia nursing for population with high risk of hypoglycemia through analysis of the personal factors influencing incidence of hypoglycemia of type 2 diabetic patients during initial use of insulin.Methods There were 257 cases of T2DM hospitalized patients during initial use of insulin,among whom 80 experienced hypoglycemia.They were divided into two groups,one was the hypoglycemia group,another was the non-hypoglycemia group.Firstly,we compared the different characteristics of the two groups such as gender,BMI and HbAlc,and so on.And then,the possible risk factors of hypoglycemia were analyzed by a Logistic regression model.Finally,the most significant factors were analyzed with the ROC curve.Results These two groups were obviously different in seven elements such as BMI,Scr,HbAlc and TG,and so on.BMI and HbAlc were the most primary causes for prevention of hypoglycemia.When patients got HbAlc＜8.65％ or BMI＜26.3 kg/m2,they had more opportunity to occur hypoglycemia.Conclusions BMI and HbAlc of patients are primary causes for hypoglycemia.It is of great significance for nurses to enhance diabetes education to the patients with HbAlc＜8.65％ or BMI＜26.3 kg/m2 to alleviate the incidence of hypoglycemia.

Objective: To establish a TaqMan-MGB probe-based real-time fluorescence RT-PCR assay for avian influenza H5N6 virus used in rapid diagnosis for suspected cases and surveillance for outer environment of live poultry markets. Methods: Based on the conservative sequences of avian influenza H5N6 virus for HA and NA gene published on GenBank, specific primers and TaqMan-MGB probes were designed to develop and optimize for the dual real-time RT-PCR assay. Specificity, sensitivity, repeatability and comparison tests were carried out. Results: This dual real-time RT-PCR detection can be completed within 80 minutes. There was no cross-reaction with other subtypes of influenza virus and common respiratory pathogens. The minimum detection limit could be up to 10 copies/reaction. The correlation coefficient of standard curve for the gene of H5 and N6 were 0.999 and 0.993, and the coefficients of variation for cycle threshold were range from 0.151%-0.549%and 0.213%-0.575%, respectively. The positive and negative coincidence rates of the validation test were 100%. Conclusions This TaqMan-MGB probe-based dual real-time RT-PCR for avian influenza H5N6 virus was rapid, specific and sensitive. It will have a good use in early emergency detection of suspected cases and continuous monitoring of external environment in live poultry trade market.
