Objective To compare the differences in the use of effects of improved and traditional abdominal positioning locator card in the empty nest elderly diabetic patients with insulin pen injection. Methods 100 discharged cases of empty nest elderly diabetic patients with insulin treated were enrolled. They were divided into two groups by random digital table method, 50 cases in traditional positioning card injection group and 50 cases in improved positioning card injection group. Usage rate of two sets of locator cart, adverse reactions in local skin injection and blood glucose control were observed for 12 months. Results After 12 months, 44 cases occupied 88%in improved positioning card injection group were not about using positioning card while 30 cases occupied 60%in traditional positioning card injection group. The difference was statistical significance (P<0.05). After 12 months, only 3 cases in improved positioning card injection group appeared local injection site reactions which was significantly lower than 31 cases in the traditional positioning card injection group, and the difference was statistically significant (P<0.05);12 months later, fasting blood glucose (FBG), 2 hour postprandial blood glucose (2 h PBG), glycosylated hemoglobin (HbA 1c) of improved positioning card injection group and traditional positioning card injection group [(7.0 ±1.5) mmol/L and(7.8±1.9)mmol/L,(10.7±2.1)mmol/L and(12.3±2.2)mmol/L,(7.1±1.3)% and(7.7±1.5)%] were all decreased significantly than before. The difference was statistically significant (P<0.05). FBG,2 h PBG, HbA1c of improved positioning card injection group were decreased more significantly than that in traditional positioning card injection group and the difference was statistically significant (P<0.05). The standard rate of HbA1c [64% (32/50)] in improved positioning card injection group was higher than that in traditional positioning card injection group [42%(21/50)]. The difference was statistically significant (P<0.05). Conclusions The modified abdominal injection locator card can improve patients′positioning card usage rate, optimize insulin injection technique, reduce the occurrence of adverse reactions in local skin injection and improve the control of blood glucose.

OBJECTIVETo observe the effect of Shenshuai Yingyang Capsule (SSYYJN) in ameliorating muscle atrophy in rats with chronic renal failure (CRF) and explore the role of Wnt7a-Akt/mTOR signal pathway in mediating this effect.

METHODSMale rats were randomly assigned to 5/6 nephrectomy group and sham-operated group, and the former group was further randomly divided into CRF model group, KA group, and SSYYJN group. The size of anterior tibia muscle was examined microscopically with HE staining. Protein synthesis in the soleus muscle was investigated by (14)C-phenylalanine experiment, and the expression of Wnt7a, frizzled-7, phospho-Akt, phospho-mTOR and GAPDH were detected with Western blotting.

RESULTSThe body weight, the wet and dry weight, cross-sectional area, and muscle protein synthesis of the anterior tibia muscles, and expressions of the proteins in the Wnt7a/Akt signaling pathway all increased significantly in SSYYJN and KA groups as compared with those in the model group.

CONCLUSIONSSYYJN can effectively improve muscle atrophy in the rat model of CRF possibly by reversing the reduction in the expressions of Wnt7a/Akt signaling pathway proteins in the skeletal muscles.
