Objective To study the characteristics and prognostic analysis of 83 cases of pulmonary infection in elderly patients in emergency department.Methods Thirty-eight elderly patients with pulmonary infection from January 2013 to December 2015 in our hospital were retrospectively analyzed.Results The number of neutrophils increased in 56 patients(67.46%), the neutrophil-lymphocyte ratio increased in 69 patients(83.13%), and C-reactive protein increased in 74 patients increased(89.16 %).There was significant difference between C-reactive protein detection and neutrophil count(P<0.05).61 cases(73.49%) were complicated with other diseases.While the effect of a single antibiotic treatment is less effective.Conclusion The early symptoms of pulmonary infection in the elderly are easy to ignore, and often associated with other diseases.C-reactive protein, neutrophil-lymphocyte ratio combined with lung imaging can be more accurate response to the elderly pulmonary infection.Early detection and early treatment, combined use of antibiotics can improve the prognosis.

Objective To find out about the causes of death of child-bearing women in Shenyang so as to provide basis for the improvement of child-bearing women's reproductive health. Methods A retrospective statistical survey into the death reporting system of Shenyang was conducted and a comparison was made between various age groups of child-bearing women from 1996 to 2000 with regard to the trends of changes in death, the rank order of causes of death and deaths due to malignant tumors. Results From 1996 to 2000, the death rate of child-bearing women in Shenyang was in a state of fluctuation. The case-death ratio in urban areas was 67.24 per 100 thousand people while the case-death ratio in rural areas was 45.97 per 100 thousand. Urban women aged 35 to 49 accounted for most of the deaths among child-bearing women. The rate of death due to cancers in urban areas was markedly higher than that in rural areas. The deaths of child-bearing women due to mammary and reproductive system cancers accounted for one fourths of deaths caused by cancer, with their incidence rate in rural areas being higher than in urban areas. Conclusion More work needs to be done to improve the healthcare of child-bearing women.

Objective To investigate the effects of WeChat follow-up of relatives on knowledge cognition, change of behavior, visual acuity and blood glucose for diabetic retinopathy (DR) patients.Methods Totally 107 typeⅡdiabetic patients from January 2014 to December 2015 in the Department of Endocrinology were enrolled in the study, with the inclusion criteria of 60 years of age and older and diagnosed with diabetic retinopathy. Subjects were divided into the WeChat group (53 cases) and the control group (54 cases) based on the order of enrollment. The control group was given routine care and health education, while the WeChat group was given additional follow-up of relatives through WeChat with distribution of health education messages for the management of DM and DR once each week for 12 months. Questionnaires were used to collect information on patient's knowledge of DR prevention & treatment and behavior change, FBG, PBG, and HbA1c, and visual acuity were also collected to assess the effectiveness of the intervention. Chi-square test was used to compare the patients' cognitive rate, behavioral change and stage of retinopathy. The t-test was used to compare fasting blood glucose, 2 hours postprandial blood glucose, glycosylated hemoglobin and visual acuity. Results Cognitive Knowledge change on DR were analyzed for the following questions:the time of the first fundus examination after diagnosis of diabetes and occurrence of systemic complications; what are key measures for prevention of early blindness in patients with DR;fundus checkup requirements while blood glucose control is ideal;types of major eye complications for diabetic patients; when laser treatment should be done for DR patients; how long apart should patients check the fundus;what is the normal range of blood glucose;and the types of server damages of DR;etc. The cognitive rates of WeChat group after follow-up were as follows 88.7%, 67.9%, 56.6%, 96.2%, 79.2%, 67.9%, 69.8%, 94.3%, 75.5%. WeChat group compared with the Control group after follow-up (χ2 values were 16.77, 30.76, 16.30, 7.75, 9.68, 36.03, 9.25, 10.57and 9.41, respectively, all P<0.01), the difference was statistically significant. The results of WeChat group before and after the follow-up were (χ2 values were 19.41, 38.22, 17.90, 8.23, 9.34, 38.22, 21.81, 12.08 and 25.52, respectively, all P<0.01), the difference was statistically significant. The cognitive rate for DR risk factors for the WeChat group was 24.5% before follow-up and 43.4%after follow-up;the after follow-up difference between WeChat group and the Control group was statistically significant (χ2=5.33, P<0.05). WeChat group before and after follow-up comparison (χ2=4.21, P<0.05) was also statistically significant. For values of fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin, results of WeChat group before follow-up were as follows (13.18± 4.46) mmol/L, (16.17 ± 3.97) mmol/L, (10.18 ± 2.76)%;results of WeChat group after follow-up were (8.45 ± 2.26) mmol/L, (11.34 ± 2.34) mmol/L,(7.83 ± 1.40)% respectively. The after follow-up comparison between WeChat group and the Control group showed statistically significant differences (t values were-7.06,-7.30, and-6.37, respectively, all P<0.01). Within the WeChat group, before and after follow-up comparison were all significantly different (t values were 6.83, 7.59 and 5.54, respectively, all P<0.01). The vision of WeChat group before follow-up was 0.68 ± 0.18, after follow-up was 0.71 ± 0.20. There were no significant differences in the two groups after follow-up, before and after follow-up WeChat group, the Control group before and after follow-up about visual acuity comparison (t values were 1.02,-1.10, and 0.57, respectively, all P>0.05). The two groups of patients were compared in balanced diet, regular eating time, meal volume, wearing loose clothing and exercise shoes and socks before each exercise, exercising for more than 30 min, weekly checkup of blood glucose, blood sugar test before and after the exercise and other measurements of behavior changes were significantly different (χ2 values were 11.54, 11.77, 13.68, 5.89, 10.23 and 8.72, respectively, all P<0.01 or 0.05). There were no significant differences in self-withdrawal of medication and Retinopathy stageⅠand stageⅡpatients and between these two patient groups (χ2 values were 1.20, 0.01 and 0.01, respectively, all P>0.05). Conclusions The practice of WeChat follow-up of relatives can improve cognition ability for DR patients aged 60 years and older, it can promote the healthy behavior and the BG monitoring effectively.

The proper orthogonai decomposition (POD) method for the instatiouary Navier-Stokes equations is considered. Several numerical approaches to evaluating the POD eigenfunctions are presented. The POD eigenfunctions are applied as a basis for a Galerkin projection of the instationary Navier-Stokes equations. And a low-dimensional ordinary differential models for fluid flows governed by the instationary Navier-Stokes equations are constructed. The numerical examples show that the method is feasible and efficient for optimal control of fluids.

Background Measurement of corneal thickness is of great significance for the design of refractive surgery and the diagnosis of eye diseases,measuring equipments and technology develop rapidly in recent years.Optovue iVue OCT is a new frequency-domain optical coherence tomography (OCT),to compare its results with those of Pentacam and Visante OCT is helpful to objectively assess the clinical value of Optovue iVue OCT.Objective This study was to investigate the repeatability of corneal thickness measurement with Optovue iVue OCT and the comparatbility with Pentacam three-dimensional anterior segment analysis diagnostic system and Visante OCT.In addition,this study attempted to analyze the distribution of average corneal thickness in each quadrant by Optovue iVue OCT.Methods The corneal thicknesses of the corneal thinnest point,the central point and 3:00,6:00,9:00,12:00 zones 1 mm away from the center of the cornea were measured in 45 right eyes of 45 subjects with myopia using Optovue iVue OCT,Pentacam and Visante OCT in Tianjin Eye Hospital.Interclass correlation coefficient (ICC) was used to analyze the repeatability of measurement by Optovue iVue OCT.The agreements between Optovue iVue OCT and Pentacam or Visante OCT were evaluated by Bland-Altman test.The corneal area of 1.0-2.5 mm away from the center was divided into eight quadrants and the average corneal thickness of each quadrant was measured and analysis with Optovue iVue OCT.Results No significant difference was found in corneal thickness values for 3 times by Optovue iVue OCT (P=0.546).The ICC by Optovue iVue OCT was 99.92％,99.99％,99.96％,99.99％,99.99％ and 99.97％ at the corneal thinnest point,the central point and 3:00,6:00,9:00,12:00 zones respectively.There were significant differences among the 3 kinds of methods (P =0.000,0.001,0.000,0.003,0.002,0.000).The measured values of Optovue iVue OCT were significantly lower mean 24.20 μm than those of Pentacam (P=0.000,0.001,0.000,0.003,0.004,0.000),but only the value at 12:00 zone of Optovue iVue OCT was evidently declined in comparison with that of Visante OCT (P =0.016),there were no significant differences between all the other zones (P =1.000,0.447,0.239,1.000,1.000).While the mean corneal thickness value from Pentacam lowed by 14.01 μm in comparison with Visante OCT,all zones had significant differences (P =0.009,0.005,0.034,0.017,0.008) except the central point (P =0.056).Based on the Optovue iVue OCT,the thinnest zone was at temporal quadrant in 23 eyes (accounting for 51.11％) and at superior quadrant or super nasal quadrant in 21 eyes (both at 46.66％).Conclusions Optovue iVue OCT measurement of corneal thickness is of high repeatability and is consistent with Visante OCT in myopic eye.Optovue iVue OCT shows evident difference from Pentacam in the measurement of corneal thickness.The thinnest point of the cornea is mainly in the inferior temporal quadrant and the thickest point is commonly in superior quadrant and nasal superior quadrant based on Optovue iVue OCT.

Objective To observe the efficacy of continuous ultrasonic wave therapy on post-stroke gastrocnemius spasticity. Methods 26 patients with gastrocnemius spasticity after stroke were randomly divided into ultrasonic group and control group. The stretch therapy was used in the two groups,and the continuous ultrasonic wave therapy was added on ultrasonic group for 4 weeks. The scores of modefied Ashworth scale (mAS),the ratio of Hmax and Mmax,and the fascicle length of gastrocnemius pre and post treatment were observed and compared respectively in the two groups.Results Compared with pre treatment,the score of mAS and the value of Hmax/Mmax in ultrasonic group wrer significantly reduced post treatment(all P

Objective To compare the clinical effect and safety evaluation of three different dose regimens for treating children with viral encephalitis.Methods Totally 126 cases treated in Xi'an Central Hospital from January 2010 to December 2015 were randomly divided into observation group 1 (ganciclovir combined with gangliosides,42 cases),observation group 2 (ganciclovir combined with gamma globulin,43 cases),and control group (39 cases).The clinical effect and levels of NSE,inflammatory cytokine were compared in the three groups.Results The total effective rate in observation group 1 was 95.24％ and that of observation group 2 was 93.02％,which were significantly higher than that of control group (79.48％).The disappearance time of headache,fever,convulsions,clouding of consciousness,meningeal irritation sign,cerebrospinal fluid abnormalities,and length of stay in observation groups (both 1 and 2)were significantly shorter than those in control group (P ＜ 0.05);After therapy,the levels of NSE in three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and those in observation group were significantly lower than the control group (P ＜ 0.05);the levels of inflammatory cytokine in all three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and that of observation group 1 had no statistical difference with the normal group,whereas that in control group was significantly higher than the normal group (P ＜ 0.05).Conclusion Ganciclovir combined with gangliosides as well as ganciclovir combined with gamma globulin were both effective methods in treating children with viral encephalitis and could decrease levels of inflammatory cytokine.Ganciclovir combined with gangliosides could effectively repair nerve damage,which deserves clinical expansion.
