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.

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 evaluate the occurrence of multidrug-resistant organism (MDRO)infection in a general hospital,and take effective comprehensive intervention measures,so as to reduce MDRO infection.Methods Targeted monitoring on MDROs was performed from October 2012 to December 2013,comprehensive intervention measures were conducted,the occurrence of MDRO infection before and after intervention was compared.Results A total of 62 384 pa-tients were investigated,17.91%(n=11 176)were sent specimens for pathogen culture,606 times of culture for patients’ specimens were detected MDROs,292(0.47%)cases were MDRO healthcare-associated infection(HAI),314 were com-munity-acquired infection or colonization.MDRO infection case rate decreased from 0.65%(75/11 603)before intervention to 0.26%(36/13 875)after intervention (χ2 =21.08,P <0.05).Conclusion Comprehensive intervention measures can effectively reduce the occurrence of MDRO HAI.

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

The application of fetal echocardiography in clinical is increasing , more and more patients need de-tailed consulting services .The following suggestions are made:Echocardiographic doctors should set up the consulting service consciousness , provide consulting with patience , popularity and carefulness; the doctors should understand the patients and their family′s emotions and also pay attention to the psychological care;environmental requirements for patients′echocardiographic examination and counseling service;encouraging multidisciplinary join the participa-tion of consulting services .

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.

Objective To investigate the roles of hemopoietic stem cells (HSCs) in the pathogenesis of psoriasis. Methods HSCs were isolated from the bone marrow of a patient with psoriasis vulgaris and a normal human control. Forward- and reverse-subtracted cDNA libraries were constructed by using suppression subtractive hybridization (SSH) technique between HSCs from the patient and control. Bacterial PCR and dot hybridization were performed to screen for positive clones followed by gene sequencing, identification and functional analysis. Real time quantitative PCR was carried out to measure the mRNA expression of interferon-γ and thymosin 10 (TMSB10). Results Nine genes were screened from the forward-subtracted cDNA library which encoded interferon-γ, tyrosine phosphatase, SUMO1 activase, etc, and 8 genes including the TMSB10-encoding gene were screened from the reverse-subtracted cDNA library. The relative expression level of interferon-γ in HSCs from the patient was 47.5 times that in HSCs from the control, while the level of TMSB10 from the control was 22.6 times that from the patient. Conclusion The abnormal expression of 17 genes which encode interferon-γ, thyrosin, and so on, may be involved in the development of psoriasis.

Objective To elucidate the differences between invasive micropapillary carcinoma (IMPC) and invasive ductal carcinoma(IDC),and explore the clinicopathological and immunohistochemistry characteristics of invasive micropapillary carcinoma of the breast.Methods Invasive micropapillary carcinoma was identified in 51 patients by retrospective review of database from October 2004 to November 2007.Data were compared with 102 patients identified as invasive ductal carcinoma available in this hospital during the same period.Results Significant differences were observed in mammilla invasion,lymphatic vessel invasion,positivity of lymph node,lymph node metastatic level,extranodal extension,estrogen receptor,progestin receptor,triple negative between the two groups; while there was no significant differences between the two groups as to amenorrhea status,lesion laterality,number of metastatic lymph nodes,human epidermal growth factor receptor-2,local recurrence and distant organ metastasis.The median follow-up time of the invasive micropapillary carcinoma group were 46 months ( 16 - 75 months),and the 3-year overall survival and disease free survival was 90.2％ and 84.3％,respectively.Conclusions Invasive micropapillary carcinoma is a unique subtype of breast cancer which manifests an aggressive behavior tending to involve lymph node and extranodal soft tissues.Invasive micropapillary carcinoma of the breast had high expression of hormonal receptors,and triple negative breast cancer is less common in this type of breast cancer.
