RESUMEN
Objective To analyze the application effect of nursing intervention under the guidance of pain care quality in pain management of patients undergone orthopedic surgery, and to provide reference for the standardized management of pain in patients undergone orthopedic surgery. Methods A total of 124 cases of patients who were to undergo orthopedic surgery and admitted to hospital from January 2015 to June 2016 were selected as the research objects,and divided into the observation group and the control group using the random number table method,with 62 cases in each group.Patients in the control group were performed routine pain nursing intervention after orthopedic surgery, including pain propaganda and education, pain prevention and pain symptomatic treatment. Patients in the observation group were performed nursing intervention under the guidance of pain nursing quality indexes.The pain related indicators, pain nursing quality related indexes and pain related complications of patients in the two groups were compared. Results The scores of visual analogue scale(VAS)0 d,1 d and 3 d after the operation in the observation group were respectively 2.82 ± 0.42, 2.45 ± 0.40 and 1.85 ± 0.32, the corresponding scores in the control group were respectively 4.14±0.56,3.25±0.52 and 2.21±0.36,and the difference between the two groups was statistically significant (t=14.848, 9.601, 5.885, P<0.05 or 0.01). The sleep hours 0d,1d and 3d after the operation in the observation group were respectively(5.16±0.71)h, (6.01 ± 0.82)h and (6.84 ± 1.02) h, the corresponding sleep hours in the control group were respectively (4.12±0.62)h,(4.65±0.72)h and(6.01±0.75)h,and the difference between the two groups was statistically significant (t=8.689, 9.613, 5.162, P<0.05 or 0.01). The unplanned anesthetic medication times in the observation group and the control group were respectively(2.32±0.45)times and(3.45±0.56)times,and the difference between the two groups was statistically significant (t=12.385, P<0.01). The observation timeliness rate,nursing record pass percent,pain intervention effective rate and management satisfaction degree in the observation group were respectively 98.39%(61/62), 96.77%(60/62), 96.77%(60/62) and 96.77%(60/62),the corresponding values in the control group were respectively 88.71%(55/62),87.10% (54/62), 85.48%(53/62)and 87.10%(54/62). The difference between the two groups was statistically significant (χ2=4.810, 3.916, 4.888, 3.916, all P<0.05). The incidence rates of delayed incision healing, insomnia and constipation in the observation group were respectively 0,9.68%(6/62)and 1.61%(1/62), the corresponding incidence rates in the control group were respectively 6.45%(4/62), 24.19%(15/62) and 11.29%(7/62), and the difference between the two groups was statistically significant(χ2=4.133, 4.644, 4.810, all P<0.05).

RESUMEN
Objective To analyze the clinical effect of a bifurcated ball frame designed for undergraduate research to assist hand-knee position,avoid physical exertion and increase comfort.Methods Randomized controlled trials consisted of 260 occipital (posterior) primiparous women born during labor,and were randomly divided into the observation group and the control group with 130 cases each.The observing group's mothers were on the yoga ball on the device.The angle and height of the frame and the ball plate were adjusted according to the maternal body type,so that the yoga ball at the chest and the cross could effectively support the maternal weight loss knee burden,and both sides of the small abdominal yoga ball could be effectively posted.After the adjustment was completed,the maternal relaxes and gently shakes the body in one direction so that the small yoga ball on the ventral side forms a continuous soothing push.The control group leaned forward on both knees (with protective gear) and supported themselves with both hands or both fists,swaying the pelvis or crawling forward.Comparing the two groups of vaginal delivery rate,maternal postural maintenance time,maternal dehvery experience,and effective correction rate of occipital position.Results The time of postoperative maintenance in the observation group was (49.51 ±10.62) minutes,and that of the control group was (18.31 ± 9.72) minutes.The difference between the two groups was statistically significant (t=6.69,P <0.05).The effective correction of abnormal fetal position rate,spontaneous delivery rate and comfort rate were 82.30% (107/130),77.69% (101/130),and 99.23% (129/130),respectively in the observation group,and 27.69% (36/130),33.85% (44/130),3.84% (5/130),respectively in the control group,the differences between the two groups were statistically significant (x2 =4.06,4.15,5.61,all P <0.05).Conclusions The undergraduate design of this sort of ball delivery group has a significant effect on the extraversion of the assisted position to the fetal position.
RESUMEN
Objective To explore the relationship of vertebral artery hypoplasia (VAH) with acute posterior circulation cerebral infarction (APCCI).Methods One hundred and eighty-nine consecutive patients diagnosed as having acute cerebral infarction admitted to our hospital from March 2015 to March 2016 were enrolled in our study;retrospective analysis was performed on their clinical and radiographic data to compare the general clinical characteristics of patients with posterior circulation infarction (PCI) and anterior circulation infarction (ACI).VAH was conformed by cranial magnetic resonance angiography (MRA),vertebral artery ultrasound or cranial MRA+vertebral artery Ultrasound.The infarction lesions in VAH patients with APCCI were typed;the correlation between vertebral artery diameter's differences and National Institute of Health stroke scale (NIHSS) scores in VAH patients with APCCI was illuminated.Results In 189 consecutive patients with acute cerebral infarction,32 (16.93%) were with VAH;after exclusion of 8 with infarction in both anterior and posterior circulation,90 (49.72%) were in PCI group while 91 (50.28%) in the ACI group.Univariate analysis showed that statistical differences were noted between the two groups in triglyceride (TG) and VAH levels (P<0.05).In 23 patients with APCCI with VAH,brain stem infarction consisted of 9 patients (5 VAHs were ipsilateral to the infarction,3 VAHs contralateral and one bi-VAH),cerebellum infarction consisted of one patient (ipsilateral side),thalamus infarction 10 patients (4 VAHs were ipsilateral to the infarction,and 6 VAHs contralateral),occipital lobe infarction 2 patients (one ipsilateral and one contralateral) and cerebellum with thalamus infarction one patient (the side of VAH was ipsilateral to the cerebellum and contralateral to the thalamus).After excluding one patient with bi-VAH,in 22 patients with APCCI combined with VAH,significantly positive correlation between vertebral artery diameter's differences and NIHSS scores was noted (r=0.560,P=0.000).Conclusions It might be the best assessment standard of VAH measured by combination of transcranial MRA and vertebral ultrasound.TG and VAH may be risk factors of APCCI,and VAH could be one independent risk factor of APCCI.The side of VAH is usually ipsilateral to the brain stem and cerebellum infarction,while contralateral to the thalamus infarction in APCCI patients with VAH.Also,vertebral artery diameter's differences are positively correlated with NIHSS scores.
RESUMEN
Objective To explore the incidence of olfactory dysfunction in patients with Parkinson disease and the characteristic as well as its possible influencing factors. Methods The SS-12 was used to evaluate the olfactory function of 106 patients with Parkinson's disease and 110 healthy volunteers. The data was then compared between the two groups to investigate the correlation of olfactory function with age, gender, education, smoking, disease duration, Hohn-Yahr stage, UPDRSⅢscores, the dosage of levodopao and olfactory scores. Results Mean identification scores were significantly lower in patients(5.97 ± 2.27)than in controls(8.04 ± 2.00)(t=7.108, P=7.108). Parkinson's disease group did worse than the control group in identifying some odors including peppermint, bananas,liquorice,coffee,pineap?ple,rose and fish (P0.05). Conclusion Olfactory dysfunction occurs in Parkinson disease with an hign incidence rate. Olfactory function has nothing to do with disease duration, Hohn-Yahr stage, UPDRSⅢscores and the dosage of levodopa in Parkinson disease.
RESUMEN
BACKGROUND AND PURPOSE: Whether or not migraine can cause cumulative brain alterations due to frequent migraine-related nociceptive input in patients is largely unclear. The aim of this study was to characterize longitudinal changes in brain activity between repeated observations within a short time interval in a group of female migraine patients, using resting-state functional magnetic resonance imaging. METHODS: Nineteen patients and 20 healthy controls (HC) participated in the study. Regional homogeneity (ReHo) and functional interregional connectivity were assessed to determine the focal and global features of brain dysfunction in migraine. The relationship between changes in headache parameters and longitudinal brain alterations were also investigated. RESULTS: All patients reported that their headache activity increased over time. Abnormal ReHo changes in the patient group relative to the HC were found in the putamen, orbitofrontal cortex, secondary somatosensory cortex, brainstem, and thalamus. Moreover, these brain regions exhibited longitudinal ReHo changes at the 6-week follow-up examination. These headache activity changes were accompanied by disproportionately dysfunctional connectivity in the putamen in the migraine patients, as revealed by functional connectivity analysis, suggesting that the putamen plays an important role in integrating diverse information among other migraine-related brain regions. CONCLUSIONS: The results obtained in this study suggest that progressive brain aberrations in migraine progress as a result of increased headache attacks.

Purpose:It has been shown that the heart is a chaotic oscillator. So it is appropriiate to use the Lyapunov exponent, an important parameter to identify the nature of non-linear dynamical systems, for identifying the state of human heart. Methods:Preliminary results are obtained in this paper using Wolf's algorithm for 8 normal and 107 abnormal ECG recordings. Results:Significant differences are found between the Lyapunov exponents of normal ECG and ECG with obvious coronary stenosis (OCS), but there is no significant difference between the Lyapunov exponents of normal ECG and ECG with mild coronary stenosis (MCS);Significant differences are also found between the Lyapunov exponents of R-R interval series of normal ECG、ECG with MCS and ECG with OCS. Conclusions:It is apparent that the R-R interval series can give us more messages about human heart, and the Lyapunov exponents of ECG and R-R interval series are the appropriate parameters for the identification of the physiological states of human heart. It is possible to use Lyapunov exponent for early diagnosis of Coronary Heart Disease.
