Objective To explore the characteristic and the rule of flash-visual evoked potentials (F-VEP) of SD rats after optic nerve injury in different grades. Methods By using APS-2000 multifunctional electric physiological instrument, changes in F-VEP were observed in normal optic nerve and injured optic nerve (crushed in 3 grades) in rats. The latency and amplitude of F-VEP wave, were recorded and statistically. Results The F-VEP wave was reliably displayed with characteristic curve. The L5b was(53.67?3.12)ms and A5 was(17.83?5.91)?v. The latency of F-VEP in rats with optic nerve injury in different grades showed a significant prolongation, and the amplitude showed a significant decrease compared with normal rats (P

To investigate the efficacy of Qiangxin Mixture in patients with congestive heart failure (CHF).

Ventilatory volumes and respiratory flow rate during quiet and rapid respiration were measured in 480 healthy pilots of our Air Force. The mean values were: VE, 9.58?1.74 1/min; MVV, 154.69?19.48 l/min; PIFR, 23.56?4.60 l/min; and FPIFR, 182.388?29.95 l/min.Regression analysis showed that they correlated well with each other as well as with body surface area (BSA), age, sitting height etc. The regression. formulae are Y = 2.97398 + 3.74173X2 for VE, Y = 103.921-0.839956X1 + 44.4811X2 for MVV, Y = 20.2761+0.735782X4 for PIFR, and Y = 99.9757-0.69924X1+ 59.7506X2 for FPIFR, where X1 stands for age, X2 for BSA, and X4 for vital capacity.The above results should provide a valuable physiological basis for designing aircraft oxygen equipment,for laying down the standard of on-board oxygen supply, and for pulmonary functional tests in pilots.

Objective:To summarize the development of the HIV/AIDS designated hospital system, analyze the main issues and explore solutions for this system. Methods:184 leaders/experts of three levels of healthcare facilities ( provinces, cities and counties) from 30 provinces engaged in AIDS prevention and control for over five years, and 2,432 people living with HIV/AIDS(PLWHA) from seven provinces were investigated through two different question-naires. Results:According to the staff responses, the issues of surgery and hospitalization are difficult and outstand-ing for PLWHA due to the current designated hospital system with scores of 6. 49 in severity. Of the ten largest prob-lems, ranked third is the need for improved AIDS prevention and control. 2 367 (97. 3%) PLWHAs had an aware-ness of the designated hospitals, 1,376 received treatment in the designated hospitals, and 85. 5% believed that the illness was effectively treated, while 9. 0% thought that the medical technology of the designated hospital was limited;18 . 7% of hospitalized HIV/AIDS patients or those who received surgery experienced prevarication by the non-des-ignated hospitals. Policy analysis shows that China’s designated hospital system for PLWHA has developed gradually with the characteristics of periodic and temporary changes. Conclusion:The designated hospital system for PLWHA in China has played an important role, but there are still several problems. The government should improve the existing system by strengthening the comprehensive medical service capacity of designated hospitals, improving the mechanism of consultation and referrals, coordinating the non-designated hospitals to provide technical support, reducing dis-crimination and fear from medical staff against HIV/AIDS, decreasing the risk of occupational exposure, and enhan-cing the communication among hospitals, CDCs and patients.

Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.

Objective To investigate the image characteristics and clinical application of 18F-FDG PET/CT in autoimmune pancreatitis (ALP).Methods The PET/CT images from six male patients (age ranging from 51 to 78(average 69) years) with AIP from 2005 to 2012 were studied retrospectively.Of the six patients,two had follow-up PET/CT images after steroid therapy.The morphologic abnormality was visually analyzed and SUV was calculated.Scores were obtained according to the SUV of pancreas compared with that of the liver (3 =SUV higher than liver,2=SUV similar to liver,1 =SUV lower than liver).The difference between the regular and delayed SUV was compared by paired t test using SPSS 17.0.Results All of the 6 patients showed diffuse FDG uptake in the entire pancreas with SUVmax of 3.2-6.0(5.2± 1.1).Five patients had score 3 and one had score 2.Five patients had delayed scan,of which 4 had increased uptake (SUVmax5.3-7.2),but the SUVmax was not significantly different compared to that before delay scan (4.8-6.0,t =-2.424,P＞0.05).Five patients showed extrapancreatic uptake,especially in the salivary glands.After the steroid therapy,the enlarged pancreas reduced and the intense uptake of the pancreas disappeared.The extrapancreatic uptake showed coinstantaneous remission.Conclusions Increasing FDG uptake at entire pancreas was observed in patients with AIP.18F-FDG PET/CT may be useful for detecting AIP and the associated extrapancreatic uptake,and monitoring the change after therapy,yet it needs further evaluation.

Objective To explore methods of quickly identifying loopholes in medical quality management and to improve medical quality by means of analyzing low-risk death cases.Methods Two rounds of analysis of 1 14 low-risk death cases of hospitals in Beijing in 2012 in terms of data quality and medical procedures,in an effort to identify problems and to verify the feasibility and accuracy of the method through interaction with other data.Results Totally 585 760 inpatients were discharged in 2012 from 21 hospitals,of whom 1 5 1 1 93 being low-risk cases.Such cases included 1 14 low-risk death cases, accounting for 0.01 9% of the total discharged,and 0.075% of low-risk discharged cases.Analysis of these medical records found 50 cases of problematic diagnosis (43.86%),45 cases of possible defects in diagnosis and treatment (39.47%),39 cases of missing items of secondary diagnosis (34.21%),and 28 cases of missing items of surgery/operation (24.56%). Some of the abovementioned cases had overlapping mistakes.Conclusion Analysis of low-risk death cases can help focus among massive data of medical records,problems of diagnostic and therapeutic insufficiency,pinpointing common problems in medical service and improving medical quality and fine management of hospitals.

Objective To explore the intervention effect of evidence-based nursing on the health behavior of elderly hypertensive patients in the community.Methods 187 elderly hypertensive patients who were hospitalized in December 2015 and met the inclusive criteria were divided into observation group (n=93) and control group (n=94).The observation group received evidence-based nursing according to the evidence-based medical system evaluation while the control group was given regular nursing both for 6 months.The clinical efficacy of two nursing modes was observed and the differences between pre-intervention and pose-intervention and groups were recorded and analyzed with a self-designed questionnaire, drug compliance questionnaire and health behavior scale.Results In the observation group, the blood pressure was effectively controlled or reduced, treatment compliance was significantly increased and body mass index (BMI) was within the ideal range 6 months later.Scores of unhealthy behaviors such as those in living habits and mental stress were lower than those in the control group, which showed significant difference (P<0.05).There was no significant difference in activity participation between the two groups (P>0.05).Conclusion Evidence-based nursing intervention can effectively control the hypertension, improve the treatment compliance of the community elderly hypertension patients and help lead them to a more positive and healthier life style.

Objective To determine the value of 18F-FDG PET/CT in the detection of subsolid pulmonary nodules.Methods The 18F-FDG PET/CT imaging data of 44 patients (35 males,9 females,mean age (68.05±9.89) years) with 49 subsolid pulmonary nodules were retrospectively analyzed.There were 28 pure ground-glass nodules (pGGN) and 21 part-solid nodules (PSN),which were all confirmed by postsurgical pathology or imaging results during follow-up.The lesion size (dmax),ground-glass opacity (GGO) percentage,SUV retention index (RI),and the positive rates on PET images were accessed.The correlation between SUVmax and lesion size and GGO percentage was analyzed by Pearson correlation analysis.The SUVmax between benign and malignant pGGN,and that between malignant pGGN and PSN,were compared using two-sample t test.The diagnostic accuracy was compared using x2 test.Results (1) Six pGGN were benign while 43 nodules (including 22 pGGN and 21 PSN) were malignant among the 49 nodules.(2) SUVmax was positively correlated with lesion size (r=0.500,P＜0.05) and was negatively correlated with GGO percentage (r=-0.605,P＜0.05) for PSN,while SUVmax was positively correlated with lesion size (r=0.375,P＜0.05) for pGGN.(3) SUVmax was not significantly different (t =-0.813,P＞0.05) between 6 benign pGGN (0.78±0.25,range:0.50-1.20) and 22 malignant pGGN (0.91±0.34,range:0.40-1.70);SUVmax of 21 malignant PSN (2.10±1.16,range:0.60-5.60) was higher than that of 22 malignant pGGN (t=-4.645,P＜0.05).(4) When a nodule's activity being equal to or greater than that of mediastinal blood-pool was defined as malignancy,the accuracy rate of PSN (66.7％,14/21) was significantly higher than that of pGGN (9.1％,2/22; x2 =15.244,P ＜0.05).Based on the criteria for malignancy of RI＞10％,the accuracy rates for PSN and pGGN were 65.0％ (13/20) and 45.8％ (11/24),respectively (x2 =1.616,P＞0.05).Conclusion 18F-FDG PET/CT shows no clear advantage for diagnosis of pGGN,but is helpful for PSN.

[ABSTRACT]OBJECTIVETo investigate the relationship between food allergen specific IgE, IgG and allergic rhinitis, and to explore the significance of food allergen in the diagnosis and prevention of allergic rhinitis.METHODSTen kinds of food specific IgE were detected by Western blot and 14 kinds of food specific IgG were detected by ELISA in 2860 allergic rhinitis patients. The positive results of specific IgE and specific IgG were retrospectively analyzed.RESULTSThere was no difference in positive rate of allergen in patients with different gender.
