Objective To analyze the correlation of traditional Chinese medical constitution types withcardiovascular risk factors in community hypertension patients. Methods We defined the constitution types of 1108 community hypertension patients, created personal health archives and provided routine examination for the subjects. After that, we input and analyzed the relevant data and results by computer. Results In 1108 cases of hypertension patients, 229 (20.67%) were defined as harmony physique, 879 (79.33%) as biased physique. In patients with biased physique, phlegm-dampness physique accounted for 25.54% (283 cases) , and then came yin deficiency physique and Qi deficiency physique, which accounted for 15.16% (168 cases) and 13.18% (146 cases) , respectively. The biased physique was dominated by single biased physique with a total of 590 cases ( 67.12%) , but the complex physique was also in large quantity, with a total of 289 cases ( 32.88%) . The complex physique consisting of two kinds of single physique was commonly seen in the patients with complex physique, accounting for 15.70%. The complex physique consisting of more kinds of single physique had less percentage. Phlegm-dampness physique was a kind of physique involving the most cardiovascular risk factors. Patients with phlegm-dampness physique had higher incidence of overweight, abnormal lipid level, family history of cardiovascular disease, lack of physical exercise and electrocardiographic abnormality, and the difference was statistically significant compared with other physique types ( P<0.05 or P<0.01) . Conclusion Phlegm-dampness, yin deficiency and Qi deficiency physique are the three commonly-seen constitution types in hypertension patients. Phlegm-dampness physique is the most commonly-seen biased physique and is also a kind of physique involving the most cardiovascular risk factors. Prevention and management in consideration with the constitution characteristics and cardiovascular risk factors will be a new prospective method for the treatment of hypertension patients in community.

Objective To study the correlations among lumbosacral anatomical structure variations and herniation of intervertebral disc.Methods Through analyzing lumbar CT images of 684 patients with lumbocrural pain between 15 to 24 years old, the anatomical variations of spondylolysis, scoliosis deformity, lumbosacral transitional vertebra, subfissure, lumbosacral angle and others (including vertebral muscles beside, spines, transverse process on both sides) were observed, and the correlations among these anatomical variations and herniation of intervertebral disc were analyzed.Results The correlations among these above mentioned anatomical variations and herniation of intervertebral disc were 93.6%,92.3%,87.5%,81.3%,72.1%,53.3% respectively.In 91.4% of patients, the lumbosacral anatomical structure variations suffered herniation of intervertebral disc at the same time.But only 36.2% of patients suffered herniation of intervertebral disc without lumbosacral anatomical structure variations.Conclusion Lumbosacral anatomical structure variation is the main reason of herniation of intervertebral disc on teenagers.CT examination,which can reflect the correlation between them.

OBJECTIVES:
Myocardial ischemia reperfusion injury (IRI) occurs occasionally in the process of ischemic heart disease. Sevoflurane preconditioning has an effect on attenuating IRI. Preserving the structural and functional integrity of mitochondria is the key to reduce myocardial IRI. Silent information regulator 3 (SIRT3), a class of nicotinamide adenine dinucleotide (NAD+) dependent deacetylases, is an important signal-regulating molecule in mitochondria. This study aims to explore the role of mitochondrial NAD+-SIRT3 pathway in attenuating myocardial IRI in rats by sevoflurane preconditioning.
METHODS:
A total of 60 male Sprague Dawley (SD) rats were randomly divided into 5 groups (n=12): A sham group (Sham group), an ischemia reperfusion group (IR group), a sevoflurane preconditioning group (Sev group, inhaled 2.5% sevoflurane for 30 min), a sevoflurane preconditioning+SIRT3 inhibitor 3-TYP group (Sev+3-TYP group, inhaled 2.5% sevoflurane for 30 min and received 5 mg/kg 3-TYP), and a 3-TYP group (5 mg/kg 3-TYP). Except for the Sham group, the IR model in the other 4 groups was established by ligating the left anterior descending coronary artery. The size of myocardial infarction was determined by double staining. Serum cardiac troponin I (cTnI) level was measured. The contents of NAD+ and ATP, the activities of mitochondrial complexes I, II, and IV, the content of MDA, the activity of SOD, and the changes of mitochondrial permeability were measured. The protein expression levels of SIRT3, SOD2, catalase (CAT), and voltage dependent anion channel 1 (VDAC1) were detected by Western blotting. The ultrastructure of myocardium was observed under transmission electron microscope. MAP and HR were recorded immediately before ischemia (T0), 30 min after ischemia (T1), 30 min after reperfusion (T2), 60 min after reperfusion (T3), and 120 min after reperfusion (T4).
RESULTS:
After ischemia reperfusion, the content of NAD+ in cardiac tissues and the expression level of SIRT3 protein were decreased (both P<0.01), and an obvious myocardial injury occurred, including the increase of myocardial infarction size and serum cTnI level (both P<0.01). Correspondingly, the mitochondria also showed obvious damage on energy metabolism, antioxidant function, and structural integrity, which was manifested as: the activities of mitochondrial complexes I, II, and IV, ATP content, protein expression levels of SOD2 and CAT were decreased, while MDA content, VDAC1 protein expression level and mitochondrial permeability were increased (all P<0.01). Compared with the IR group, the content of NAD+ in cardiac tissues and the expression level of SIRT3 protein were increased in the Sev group (both P<0.01); the size of myocardial infarction and the level of serum cTnI were decreased in the Sev group (both P<0.01); the activities of mitochondrial complexes I, II, and IV, ATP content, protein expression levels of SOD2 and CAT were increased, while MDA content, VDAC1 protein expression level, and mitochondrial permeability were decreased in the Sev group (all P<0.01). Compared with the Sev group, the content of NAD+ in cardiac tissues and the expression level of SIRT3 protein were decreased in the Sev+3-TYP group (both P<0.01); the size of myocardial infarction and the level of serum cTnI were increased in the Sev+3-TYP group (both P<0.01); the activities of mitochondrial complexes I, II, and IV, ATP content, protein expression levels of SOD2 and CAT were decreased, while MDA content, VDAC1 protein expression level, and mitochondrial permeability were increased in the Sev+3-TYP group (all P<0.01).
CONCLUSIONS
Sevoflurane preconditioning attenuates myocardial IRI through activating the mitochondrial NAD+-SIRT3 pathway to preserve the mitochondrial function.
