Objective To evaluate application of quality care in prevention of general surgery wound infection in elderly patients. Methods 116 cases of elderly patients undertook general surgery from October 2013 to October 2014 were selected in alphabetical order by pinyin of last name as the research objects, who were divided into the observation group (58 cases) and control group (58 cases) by lottery. The control group received routine care, the observation group received quality care. The occurrence of wound infection and the hospitalization time were compared. Results The incidence of wound infection of the observation group was 6.9%(4/58), which was lower than that of the control group [24.1%(14/58),χ2=6.576, P<0.05]. The hospitalization time of the observation group was lower than that of control group [(22.6±3.2) d vs.(28.6±3.8) d, t=5.401, P<0.05]. Conclusions Quality care contributes to reduce the incidence of wound infection on general surgery incisions of elderly patients, and promotes the recovery of patients.

Background Central corneal thickness (CCT)is an important parameter to evaluate corneal healthy status and is crucial for surgical planning.However,clinical study found that the center of cornea does not correspond to the thinnest point of cornea.Thus,it is essential to characterize the minimum corneal thickness(MCT) and its location.Objective Present study was to determine the thickness and location of MCT and its relationship to the fellow eye using Pentacam High Resolution technique.Methods The 564 eyes from 282 Chinese myopic patients were reviewed in this study.The CCT,MCT,pupillary central corneal thickness(PCT) and x-y coordinate of thinnest point were bilaterally measured.Written informed consent was obtained prior to the ocular biomedical measurement.Results CCT was (540.07±31.78) μm in the right eyes and (539.24±31.06) μm in the lefi eyes; PCT was (540.25±30.75)μm in the right eyes and (539.48±31.00)μm in the left eyes.MCT was (537.87± 31.91)μm in the right eyes and (536.35±31.24)μm in the left eyes,showing significant differences in all the parameters between the right eyes and left eyes expect for PCT(CCT:P=0.046;PCT:P=0.065 ;MCT:P=0.000).The C CT,PCT and M CT were significantly correlated between the right eyes and left eyes (r =0.97,0.97,0.98,P＜ 0.01).Bland-Altman plot showed a good consistence between the both eyes.The mean distance from the center was (0.50±0.21) mm in the right eyes and (0.56±0.22)mm in the left eyes,showing a significant difference (P =0.000).The difference between CCT and MCT was approximately (2.20±1.74)μm in the right eyes and (2.88±1.75) μm in the left eyes.The location of MCT in both the right eyes and left eyes tended to symmetry along the vertical midline.The distance between the R (x,y) to transformed L (x,y) was (0.29 ± 0.17)mm and the angular distance was (28.28±28.21)degree.Conclusions This study offers a range of MCT and its location in Chinese myopic patients.The difference exists between the CCT and MCT in bilateral eyes.The location of the thinnest point tends to be symmetrical along the vertical midline between the both eyes.The changes of these parameters may be helpful for the diagnosis of some corneal diseases.

Fourteen compounds were isolated from 95% ethanol extract by silica gel, MCI, and ODS column chromatography. These compounds were respectively identified as quercetin (1), kaempferol (2), (+)-catechin (3), fraxin (4), protocatechuic acid (5), gallic acid (6), methyl gallate (7), ethyl gallate (8), apocynol A (9), baccatin (10), cerevisterol (11), ellagic acid (12), 3, 3',4'-tri-0-methylellagic acid(13) and N-benzoyl-L-phenylalaninyl-N-benzoyl-L-phenylalaninate(14) by analyzing their spectral data and comparing with the previously reported literatures. Except for gallic acid (6), all other compounds were isolated from this plant for the first time. Compounds 1, 2 and 6 showed moderate anti-proliferation activities on tumor cells.

In this study, we applied generalized autoregressive conditional heteroskedasticity (GARCH) model to conditional fluctuation characteristics of heart rate variation (HRV) series (congestive heart failure, Normal), with all the data from PhysioNet ECG database. Research results proved the existence of condition fluctuation characteristic in the series of changing rate of HRV. In the GARCH model family, threshold GARCH (1,1)(TGARCH (1,1)) model performs best in fitting changing rate of HRV. Although the structure of ARCH (1) model is simple, its error is the closest to that of TGARCH (1, 1) model. The results also showed that the difference was obvious between disease group and normal group. All these results provide a new method to the research and clinical application of HRV.
