2.Research approach of cervical kyphosis
Orthopedic Journal of China 2006;0(18):-
According to the concept of sagittal spinal balance, the alternating curves of cervical and lumbar lordosis and thoracic and sacral kyphosis enable the head to be positioned over the trunk and pelvis. But the sagittal imbalance represents departure from this ideal form. Cervical kyphosis may represent the most disabling of these imbalances, for it can cause pain, postural difficulties, or neurologic deficit. A summary and discussion is reviewed regarding the anatomy, biomechanics, etiology, clinical presentation, laboratory examination and treatment of this condition.

Chinese Journal of Anesthesiology 1995;0(12):-
Objective To investigate the effect of isovolumic hemodilution with 6% hydroxyethyl starch (HES) (200/0.5) on expression of intercellular adhesion molecule-1 (ICAM-1) after global cerebral ischemia-reperfusion in rats. Methods Eighty-four male Wistar rats weighing 230-280g were randomly divided into 3 groups: group Ⅱ sham operation (S , n = 20); group ischemia-reperfusion (Ⅱ , n = 32) and groupⅢ hemodilution with 6% HES (200/0.05) (H, n =32) . Group Ⅱ and group Ⅲ were further divided into 4 equal subgroups with 8 animals in each subgroup: 2h, 4h, 8h and 12h after beginning of reperfusion. Global cerebral ischemia was produced by permanent occlusion of bilateral vertebral arteries and cross-clamping of bilateral common carotid arteries for 10min and then clamping was released for reperfusion. In group Ⅲ acute normal volumic hemodilution was performed at 10 min after reperfusion was begun. 1ml/100g of blood was removed from artery and equal volume of 6% HES(200/0.5) was infused into the vein simultaneously. Hct was checked before and after hemodilution. The animals were decapitated at designed time and brain tissue was removed from ischemic area and frozen in liquid nitrogen. ICAM-1 expression was determined by using immunohistochemical technique. Results ICAM-1 expression significantly increased after 2h, 4h, 8h and 12h reperfusion in group Ⅱ and Ⅲ as compared with in group Ⅰ (P

Objective To investigate the effect of hemodilution with different plasma substitutes on the expression of tumor necrosis factor-? (TNF-?) and interleukin-1 (IL-1 ) in brain tissue after global cerebral ischemia-reperfusion (I/R) in rats.Methods 116 male Wistar rats weighing 230-280 g were randomly divided into 4 groups: group S ( n = 20) sham operation; group Ⅰ ( n = 32) I/R; group H (n = 32) I/R + hemodilution with 6% hydroxyethyl starch (HAES, 200/0.5) and group G ( n = 32) I/R + hemodilution with gelatine solution. Group Ⅰ, H and G were further divided into 4 equal subgroups with 8 animals in each subgroup according to the duration of reperfusion: 1, 3, 6, 12 h. Global cerebral ischemia was produced by permanent occlusion of bilateral vertebral arteries and cross-clamping of bilateral common carotid arteries for 10 min. The clamping was then released for reperfusion. Global cerebral ischemia was confirmed by coma, loss of righting reflex, bilateral pupil dilation and loss of pain sensation. In group H and G acute hemodilution was performed at 10 min after the beginning of reperfusion. 1 ml? 100 g-1 of blood was removed from the right femoral artery and equal volume of plasma substitute was infused into left femoral vein simultaneously within 5 min. Hematocrit was checked before and after hemodilution. The animals were decapitated after being reperfused for different periods of time as planned and the brains were immediately removed. MTT bioassay and radioimmunoassay techniques were used to determine the IL-1 activity and TNF-? content of the brain tissue respectively. Results The IL-1 and TNF-? levels of brain tissue at 1, 3, 6, 12 h after reperfusion was started were significantly higher in group Ⅰ, H and G than in group S (P

Chronic pain is a common clinical disease,which brings great burden to the patients.However,the pathogenesis underlying of chronic pain is complicated,which is affected by many factors,such as physiology,psychology and society.Therefore,the treatment of chronic pain has been a problem in clinical practice.Considering its complexity,a single way of treatment usually could not reach satisfactory results,so combination therapy is often used to treat chronic pain at present.The combination therapy includes pharmacological treatment,psychological approaches,interventional treatment,self management and so on.The treatment plans are distinct for different types of chronic pain,even the individual patients with the same kind of pain.The emergence of interdisciplinary rehabilitation programs shed light upon the treatment of chronic pain recent years.This paper reviewed the research on chronic pain treatment,in order to provide theoretical basis for clinical practice.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.

Objective To observe the clinical characteristics and prognosis in children with high take -off coronary artery.Methods The clinical characteristics,laboratory examinations and prognosis were retrospectively ana-lyzed in 49 children with high take -off coronary artery who had been admitted to Beijing Children′s Hospital Affiliated to Capital Medical University from April 2009 to December 201 2.Results Among 49 medical records of children with high take -off coronary artery,34 cases were male and 1 5 cases were female,with a mean age of (9.28 ±4.42)years old,and the youngest patient was 1 3 months old,and the oldest patient was 1 7 years and 2 months old.The 64 -section multidetector CT angiography of all patients showed one or both coronary arteries originated from 1 .0 cm higher than the junction area of sinus and aorta,including 38 high take -off of the left coronary artery,7 high take -off of the right coronary artery and 4 high take -off of both coronary arteries.The chief complaints of the patients included chest pain (22 cases,44.90%),chest tightness(1 3 cases,26.53%),declining of exercise tolerance(7 cases,1 4.29%),fatigue (5 cases,1 0.20%),palpitation(3 cases,6.21 %),syncope(1 case,2.04%).Electrocardiogram(ECG)of those pa-tients showed ST -T changes,atrioventricular block,sinus tachycardia,pathological Q -wave,proiosystole and bundle branch block.Ultrasonic cardiogram(UCG)indicated 1 4 patients with the enlarged left ventricle,including 2 patients with ejection fraction lower than 60%.After 1 0 days hospitalization,the anesis of chest pain and chest tightness were significantly different statistically(P <0.05),but there was no significant difference in ECG and UCG.Thirty -nine out of 49 children were followed for 1 year.After 3 months,6 patients with ST -T problem showed normal ST -T segment. After 6 months,1 0 patients with ST -T problem showed normal ST -T segment.After 1 year,1 7 patients with ST -T problem showed normal ST -T segment.Conclusions High take -off coronary artery is a rare malformation of the coronary artery,which can cause myocardial ischemic,leading to multiple clinical manifestations and may result in ECG changes and the left ventricle enlargement.High take -off coronary artery can be confused with myocarditis and myocar-dial lesion clinically.Patients receiving systemic treatment may have their symptoms released,but ECG and UCG may not relieve in a short term.Patients with high take -off coronary artery need long -term observation.
