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.

Objective To study the molecular mechanism of injection with hepatocyte growth factor (HGF) at different doses on angiogenesis in myocardium of dogs with acute myocardial infarction (MI).Methods Sixteen 1.5-year-old male hybrid dogs,weighing 11-13 kg,were divided into 500 ?g HGF treatment group,1 000 ?g HGF treatment group,sham operation group,and no MI interference group,4 dogs in each group.Expressions of VEGF,HGF,CD31,and platelet factor Ⅷ in myocardium of dogs with MI were detected,the number of micro blood vessels was calculated,and correlation between angiogenesis and expression of HGF and VEGF was analyzed in 28 d after the model was established.Results HGF gene therapy could up-regulate the expression of CD31 and VEGF.The expression of CD31 and VEGF mRNA was 0.82 and 0.39 respectively in 1 000 ?g HGF group,and 0.47 and 0.21 respectively in 500 ?g HGF group.The expression of VEGF mRNA was 0.09 and no expression of CD31 mRNA was found in MI group.HGF could increase the angiogenesis in infracted myocardium.The microvascular density was 126.4?10.6,79.8?6.0,and 21.7?2.5/mm2,respectively,in 1 000 ?g HGF group,500 ?g HGF group,and MI group (P

Objective:To evaluate the diagnostic efficacy of SPIO in known liver lesions.Methods:30 patients with known liver lesion were underwent MRI.The contrast noise rate(CNR)of lesion to liver and the relative enhancement rate(RE)of liver were measured at 10、30、45、70 min and 16 hour after SPIO was injected.The dynamic curve of signal-noise were made and analysed.Results:The study shown that the hepatic parenchyma had a significantly negative enhancement in T 2 weight of SE and GRE sequence.However,the signal intensity showed few changes in hepatic metastases and only a little positive or negative enhancement in angioma、HCC and FNH.Conclusion:SPIO,as a negative contrast media for liver,has a significantly efficacy to show liver lesions,and as liver lesion-specific contrast MR agent,is worth being explored.

Objective To investigate the clinical application of acupuncture combined with general anesthe -sia in gynecologic laparoscopic surgery .Methods 60 ASA( the American society of anesthesiologists )Ⅰ-Ⅱpatients undergoing elective gynecologic laparoscopic surgery were randomly divided into the acupuncture group and control group.Patients in the acupuncture group were chosen Hegu (LI 4),Neiguan(PC 6) on both sides.After acupuncture, the two acupoints,electroacupuncture stimulated 20-30min,then administered general anesthesia ,electroacupuncture until surgery finished ,the control group received general anesthesia only .The drug dosages of the two groups was regu-lated,maintained anesthesia depth bispectral index ( BIS) between 40 and 60.The changes of the blood pressure ( BP) ,heart rate and BIS of the two groups at the same time points were observed;the propofol and remifentanil dos-age after the surgery ,the awaken time and extubation time ,OAA/S score and pain score after wake ,the happening of restlessness,chills,nausea and vomiting ,the usage of narcotic analgesics postoperation ,and the intraoperative aware-ness were recorded .The effect of acupuncture combined with general anesthesia was evaluated .Results Anesthetic dosage propofol of the acupuncture group [(7.44 ±1.30)μg· kg-1· h-1] was less than [(8.66 ±1.24)μg· kg-1· h-1] of the control group (t=3.720,P=0.001),remifentanil dosage was also less than the control group [acupunc-ture group (10.59 ±2.58)μg· kg-1· h-1,control group (11.93 ±2.27)μg· kg-1· h-1,t=2.168,P=0.034]. Compared with the basic value ,the BP values were higher at the time of intraoperation ,waking,extubation and 10 min after extubation (all P<0.05),the acupuncture group had more stable BP .Compared with the acupuncture group , heart rates in the control group were faster at extubation and 10min after extubation .Recovery time and extubation time of the acupuncture group were (9.05 ±2.36)min and (1.61 ±2.40)min,which were shorter than (12.50 ± 3.20)min and (15.90 ±3.37)min of the control group (P<0.05).Pain score(VAS) in the acupuncture group was lower than that of the control group .Consciousness score was higher in the acupuncture group ,the incidence rates of restlessness,chills were less.Conclusion The use of acupuncture combined with general anesthesia in gynecologic laparoscopic surgery can reduce the dosage of general anesthetics ,shorten the awaken time and extubation time ,increase the OAA/S score of the patients ,relieve pain ,and the recovery quality is higher .
