Modern Clinical Nursing 2016;15(1):62-65
Objective To explore the effect of community family nursing intervention on glycemic control of type 2 diabetic patients. Methods Ninety-two patients with type 2 diabetes after discharge in 6 communities of Tianhe District in Guangzhou were divided into a study group and a control group , 46 cases in each . The control group received routine care , while patients in the study group received additional community family nursing intervention, including personalized health education, diabetes family day and sharing, telephone follow-up and family home visits. The fasting plasma glucose, 2h-postprandial glucose and glycosylated hemoglobin A1c were compared. Results There were no significant differences in fasting plasma glucose, 2h-postprandial glucose and glycosylated hemoglobin A1c (all P>0.05). After intervention, there were significant differences in the three eridoxes between the two groups(all P<0.05). Conclusion The community family nursing intervention is of great importance to control the blood glucose, improve the therapeutic compliance and self-management ability in patients with type 2 diabetes.

We reported a simple and fast fluorescence system based on quantum dots ( QDs ) to detect glutamate dehydrogenase ( GLDH) , which inverted glutamate to α-ketogrutarate using NAD+ as a coenzyme. The fluorescence of CdTe QDs was quenched by nicotinamide adenine dimucleotide ( NAD+) through an electron transfer pathway, and the quencher NAD+ could be consumed by adding NAD+-dependent enzymes and corresponding substrates. Based on this principle we introduced GLDH to consume NAD+ in the QDs/NAD+ system, leading to the enhancement of the fluorescence intensity of QDs, which was in proportional to the amounts of GLDH added. Using this fluorescence system, we measured GLDH in a wide concentration range from 10 U/L to 1000 U/L, which was of significance in clinical diagnosis of different kinds of liver diseases.

Objective To explore the influence of continuity care model on how to deal with medical waste of insulin injections among domestic patients Methods Consecutive diabetes patients using the home insulin injections were recruited as the the members of our Diabetes Education Classfrom September 2014 to March 2015. The home medical waste disposal was brought into the content of diabetes education;problems were intervened through the continuity care model. Using the questionnaire survey to investigate the cognitive and disposal of patients on medical waste, to compare the difference of results of questionnaire before and after the intervention. Results The cognitive rate of medical waste after intervention was 97.70%(212/217),while the cognitive rate before intervention was 3.69%(8/217), the difference was significant (χ2=383.63,P<0.01). Disposal of diabetes patients using the home insulin injections had improved after the continuity care, the rate of dealing with medical waste according to specification after the intervention was 91.24% (198/217),while the rate before the intervention was 3.23%(7/217), the difference was significant (χ2=337.26,P<0.01). Conclusions The continuity care model standardized the behavior of patients for disposal of medical waste, reduced the environment pollution of medical waste and decreased the spread of disease.

[Objective] To investigate the effect of sevoflurane and isoflurane anesthesia on the renal function of patients with severe fracture after surgery.[Methods] Sixty-two patients with severe fracture who needed surgery were enrolled and all received general anesthesia.All the patients were divided by random digits table method into two groups with 31 cases each:sevoflurane group(anesthesia maintenance with 1.5%-3.0% sevoflurane)and isoflurane group(anesthesia maintenance with 1.5%-3.0% isoflurane).The patients in two groups received 0.1-0.2 μg/(kg·min)remifentanll continuous intravenous infusion and atracuurium intermittent intravenous injection for anesthesia maintenance.Serum creatinine(SCr)and blood urea nitrogen(BUN)in two groups after surgery were compared,as well as the number of hemodialysis.[Results]SCr and BUN at 1,3,7 d after surgery in two groups were significantly lower than those before surgery[seveflurane group:(517 ± 187),(163 ± 110),(103 ± 99)μ mol/L vs.(853 ± 220)μmol/L,(17.1 ± 7.8),(9.5 ± 4.1),(9.7 ± 3.8)mmol/L vs.(21.8 ± 9.3)mmol/L;isoflurane group:(539 ± 188),(136 ± 108),(101 ± 95)μ mol/L vs.(881 ± 220)μmol/L,(17.5 ± 7.4),(9.5 ± 3.5),(9.8 ± 3.3)mmol/Lvs.(20.0 ± 8.9)mmol/L](P < 0.05).SCr and BUN between two groups at every time point after surgery had no statistical significance(P > 0.05).There was 1 case(3.2%)in sevoflurane group needed hemodialysis within 7 d after surgery,as well as in isoflurane group,and there was no statistical significance between two groups(P>0.05).[Conclusions] For patients with severe fracture who need general anesthesia and surgery,sevoflurane and isoflurane both have no significant adverse reaction to renal function.Therefore,it is acceptable for the patients to use sevoflurane for anesthesia and it is worthy of clinical popularization and application.

Cryogel is a kind of elastic, spongy hydrogel prepared via addition polymerization from monomers or cross-linking reaction from a polymer at a temperature lower than the freezing point of the solvent. Cryogel has been principally used in molecular imprinting cryogel based solid phase extraction in the field of analytical chemistry, which combines both the advantages of high selectivity of the molecular imprinting and the porous structure, high throughput of a cryogel. Molecular imprinting cryogel can be used as the stationary phase in a packed column, a monolith column, or the adsorbent in a separation membrane. A variety of molecules can act as template molecules, including small molecules, macromolecules, a certain fragment of a macromolecule, and even an inorganic ion. Both a simple template and a complex template can be used. When employing more than a molecule ( or an ion) as templates simultaneously, the method is termed as Mixed template. While high abundance components of a complex sample act directly as mixed template, we name the method as Pending template. Further, while an analogue, an isotopic label, or a fragment of the target substance acts as a template, the method is defined as Dummy template. However, the research on cryogel is insufficient and the application of the cryogel is narrow hitherto.
