Fifteen morphologically and structurally complete sacrum specimens of normotrophic adult females were choosen. Distances between posterior sacral foramina and median sacral crest,and between the cores of adjacent posterior sacral foramina were measured. Then statistical analysis was done so as to provide objective anatomical evidence for the surface localization of Baliao points. The average distance between Shangliao (BL 31) and median sacral crest was (2.08 ± 0.19) cm; and the average distance between Ciliao (BL 32) and median sacral crest was (1.75 ± 0.12) cm; Zhongliao (BL 33), (1.59 ± 0.15) cm; Xialiao (BL 34), (1.56 ± 0.15) cm. And the distance of S₁-S₂ was (2.36 ± 0.31) cm averagely; S₂-S₃, (1.98 ± 0.23) cm; S₃-S₄, (1.71 ± 0.18) cm. It is considered that to locate Baliao points, Ciliao (BL 32) needs to be ascertained firstly.

Objective To investigate the relationship between carotid arteriostenosis and atheromatous plaques with cerebral in-farction.Methods Cervical spiral CT angiography of 56 cases with cerebral infarction and 49 cases without cerebral infarction were retrospectively analysed .The difference between the two groups was compared with regard to the distribution ,nature of plaques and the degree of carotid artery stenosis.Results Of 56 patients with cerebral infarction,126 atheromatous plaques were detected in 42 patients,of which 39 were soft,34 were calcified,53 exhibited a combined nature of both calcified and soft plaque and 7 cases were plaque ulcerations (soft plaque and mixed plaque accounted for about 73%).Plaque location for carotid artery was in the bifurcation. 102 carotid arteries stenosis were found in 38 patients,which included mild stenosis in 29,moderate in 40,severe in 27 and occlusion in 6(moderate and severe stenosis accounted for about 65.7%).In the control group,28 plaques were detected in 1 1 cases,of which 6 were soft,13 were calcified and 9 exhibited a combined nature of both calcified and soft plaque.1 1 carotid arteries stenosis were found in 7 patients,included mild stenosis in 10,moderate in 1.A significant difference (P <0.05)in carotid arteriostenosis and ath-eromatous plaques between the two groups was found.Conclusion Carotid plaques and stenosis are important risk factors of cerebral infarction.Multi-slice spiral CT angiography(MSCTA)has important value in analysis of carotid artery stenosis and atheroderotic plaques.

Objective To explore the genuineness of Exocarpium Citri Grandis(ECG) from Huazhou city of Guangdong province.Methods We used the method of high performance liquid chromatography to detect the naringin content in ECG from different producing areas of Huazhou city.Random amplified polymorphic DNA analysis was used for the examination of genetic distance,and plasma-atomic emission spectrometry for the detection of soil elemental abundance of 8 elements such as aluminium(Al),kalium(K),calcium(Ca),ferrum(Fe),titanium(Ti),boron(B),magnesium(Mg),and manganese(Ma).The correlation of the above three parameters was analyzed by statistical software SPSS 11.5.Results Ca abundance in the surface soil layer had an obvious effect on the content of naringin,and the difference of Al and K abundance in subsoil layer was correlated with the genetic distance of ECG.Conclusion The genuineness of ECG is probably related with the abundance of phlopopitum in the soil of producing areas of Huazhou city.

Objective To explore the application effect of elaborate and staged teaching in the teaching of emergency nursing practice.Methods 65 cases of intern nursing students in emergency department from June 2015 to July 2015 were selected as the control group,and the traditional clinical teaching mode was adopted for this group.68 cases of intern nursing students in emergency department from August 2015 to September 2015 were selected as the experimental group,and elaborate and staged teaching was adopted to make teaching requirements in order to carry out the clinical practice teaching.The resuits of two groups of intern nursing students in theoretical score and practice score undergoing different kinds of teaching modes were contrasted and analyzed,and the teaching satisfaction degree for the intern nursing students were recorded.All the data were analyzed by t test with independent sample.Results The theoretical knowledge score [(82.0 ± 1.7) vs.(77.5 ± 2.0)],practice performance score [(80.5 ± 1.3) vs.75.5 ± 2.5)] and teaching satisfaction degree [(93.3 ± 1.3) vs.(75.5 ± 2.5)] of the experimental group were significantly better than those of the control group,and the differences were all statistically significant (P＜0.05).Conclusion Elaborate and staged teaching is helpful for nursing students to master the knowledge and clinical practice skills in emergency nursing,and can improve the teaching satisfaction of the nursing students.There is certain kind of value for promotion for this mode.

Objective To explore the role of resveratrol (RES) on cardiomyocyte hypertrophy of rat induced by isoproternol (ISO) and the effect of Res on the expression of GRP78 and GRP94 in endoplasmic reticulum stress of cardiomyocyte hypertrophy.Methods Hypertrophic model of cardiomyocytes was induced by ISO.Cardiomyocytes was divided into four group: control group, the model group, RES+ISO group and RES group.Hypertrophy status of cardiomyocytes was determined by Leica 2Q500 image analysis system measuring the cell surface area and the gene expression of ANP.The content of LDH and MDA was measured in different groups, and the protein expressions of GRP78 and GRP94 were detected by Western blot.Results Compared with control group, ISO induced cardiomyocytes hypertrophy, endoplasmic reticulum stress related factors GRP78 and GRP94 protein expression were increased, compared with ISO group, RES intervention effectively suppressed the cardiomyocytes hyper-trophy induced by ISO, reduced the protein expression of GRP78 and GRP94, at the same time, reduced lactate dehydrogenase (LDH) and malondialdehyde (MDA) release in cell medium.Conclusions Treatment of RES may protect cardiomyocytes hypertrophy, which is partially mediated by inhibiting the expression of ERS factors GRP78 and GRP94.

OBJECTIVES: The long-term trends of cognitive function and its associations with physical performance remain unclear, particularly in Asian populations. The study objectives were to determine cognitive trajectories in middle-aged and elderly Chinese individuals, as well as to examine differences in physical performance across cognitive trajectory groups. METHODS: Data were extracted from the China Health and Retirement Longitudinal Study. A total of 5,701 participants (47.7% male) with a mean age of 57.8 (standard deviation, 8.4) years at enrollment were included. A group-based trajectory model was used to identify cognitive trajectory groups for each sex. Grip strength, repeated chair stand, and standing balance tests were used to evaluate physical performance. An ordered logistic regression model was employed to analyze differences in physical performance across cognitive trajectory groups. RESULTS: Three cognitive trajectory groups were identified for each sex: low, middle, and high. For both sexes, higher cognitive trajectory groups exhibited smaller declines with age. In the fully adjusted model, relative to the low trajectory group, the odds ratios (ORs) of better physical performance in the middle cognitive group were 1.37 (95% confidence interval [CI], 1.17 to 1.59; p<0.001) during follow-up and 1.40 (95% CI, 1.20 to 1.64; p<0.001) at the endpoint. The ORs in the high trajectory group were 1.94 (95% CI, 1.61 to 2.32; p<0.001) during follow-up and 2.04 (95% CI, 1.69 to 2.45; p<0.001) at the endpoint. CONCLUSIONS Cognitive function was better preserved in male participants and individuals with higher baseline cognitive function. A higher cognitive trajectory was associated with better physical performance over time.

Objective To investigate the effect of resistance training on the rehabilitation of patients after hip replacement with the framework of the theory of planned behavior(TPB).Methods A total of 85 patients of hip fracture patients in Gansu Provincial Hospital of Traditional Chinese Medicine from July 2022 to April 2023 were selected as research objects.The patients were separated into intervention group(n=43)and control group(n=42)by random sampling.Both groups were treated with routine nursing,and the intervention group was given resistance training based on TPB.The intervention time was 3 months.The Harris hip score(HHS),36-item short form(SF-36)score and Barthel index(BI)scores of the two groups were compared before intervention,1 month and 3 months after intervention,as well as the functional exercise compliance score of the patients 3 months after intervention.Results After 1 month and 3 months of intervention,the HHS,SF-36 score and BI score of intervention group were better than those of control group,and after 3 months of intervention,the executive ability of functional exercise in intervention group was significantly higher than that of control group,and the mean difference was significant(P＜0.05).Conclusion Resistance training led by TPB can effectively improve the functional exercise compliance of patients after total hip arthroplasty,improve the muscle strength,balance ability and joint stability of patients,and then improve the daily activity ability and quality of life.

OBJECTIVES: This study investigated the seasonal impact of diurnal temperature range (DTR) on hospitalization rates for intracerebral hemorrhage (ICH) in middle-aged and elderly adults. METHODS: We collected data on the DTR and hospitalization records of ≥45-year-old patients with ICH in 2019 in Hunan Province, central China. Time-series analyses were performed using a distributed lag non-linear model. RESULTS: Overall, 54,690 hospitalizations for ICH were recorded. DTR showed a non-linear relationship with ICH hospitalization in both middle-aged and elderly populations (45-59 and ≥60 years, respectively). During spring, a low DTR coupled with persistently low temperatures increased ICH risk in both age groups, while a high DTR was associated with an increased risk in the middle-aged group only (relative risk [RR], 1.24; 95% confidence interval [CI], 1.21 to 1.27). In the summer, a low DTR combined with persistently high temperatures was linked to a higher risk exclusively in the middle-aged group. A high DTR in the autumn was correlated with increased risk in both age groups. In winter, either a low DTR with a continuously low temperature or a high DTR elevated the risk solely in the elderly population (RR, 1.37; 95% CI, 1.00 to 1.69). In the elderly group, the impact of DTR on hospitalization risk manifested within a 5-day period. CONCLUSIONS The impact of DTR on ICH hospitalization risk differed significantly across seasons and between age groups. Elderly individuals demonstrated greater sensitivity to the impact of DTR. Weather forecasting services should emphasize DTR values, and interventions targeting sensitive populations are needed.
