Objective To investigate clinical therapeutic effects after a series of improvements of multi-site combination in the simple obese patient with tumescent liposuction. Methods Before tumescence anesthetization, short-acting benzo-diazepine was used as sedative inducer. The pressure and fluid velocity of short-acting benzodiazepine were regulated and injected into deeper level of fat at first, and all of these actions decreased the pain of patients, and promote the effect of the pain tolerance. The positions of the incisions were selected to hide from view and specifically protected, which could improve looks and decrease the scar formation after operation. In later stage of operation the flaps were pressurized and slid from outside, in order to make the flaps even and smooth and to keep their thickness according to the position of the flaps and the age of the patients. Opened draining was changed to block draining after operation. Results 73 cases were taken the follow-up for 6~24 months. All cases obtained satisfactory results, except that one cases was complicated by scar hypertrophy. The changes of the circumferences were as follows: the decrease of the maximum circumference of thigh was from 2 cm to 17cm, abdomen from 3 cm to 24 cm, and buttocks from 1 cm to 3 cm. Conclusions A series of improvement of key measures enhance the clinical therapeutic effects of multi-site combination in the simple obese patient with tumescent liposuction.

Objective To evalutate the safty of hBMSCs transpalntation and to observe their migration and distribution in the brain of young macaca fascicularis. To establish a new technology platform and theoretical basis for the treatment of central nervous system diseases in children. Methods Labelled hBMSCs were transplanted into the striatum of young macaca fascicularis. Brain sections were examined to evalutate the inflammatory reaction and immunological rejection of local injection sites by HE observation and immunohistochemical staining. Migration and distribution of transplanted?hBMSCs was observed by real?time fluorescence quantitative PCR of male DNA and fluorescence microscope. Results The results showed that the direct intracerebral injection of hBMSCs did not cause systemic symptoms in animals. There is no inflammatory reaction and immunological rejection was detected, and degeneration and necrosis of neural cells and proliferation of glial cells were absent in the local injection sites. The transplanted hBMSCs survived, and migrated into the brain after 4 weeks transplantation. Its migration and distribution have certain regularity and were overlapping between transplant recipients. In addtion, hBMSCs tended to extend rostrally into the forebrain and showed preference of migrating toward the blood vessels and below the ependyma. Conculsions Intracerebral transplantation of hBMSCs is safe. And hBMSCs can survive and migrate into the brain.

Objective To investigate the impact ofα?lipoic acid(ALA)treatment on sepsis?induced acute kidney injury in rats and explore the mechanisms. Methods A total of 32 male SD rats were randomized into 4 groups:normal control group(group A),ALA?treated control group (group B),sepsis group(group C)and sepsis with ALA treated group(group D). Group A and B underwent sham operation,while CLP operations were conducted in group C and D. Rats in both group B and group D were then administered with 200 mg/kg ALA by oral gavage immediately after the surgical procedure. Twenty?four hours after the surgical procedure blood samples were obtained for the evaluation of creatinine,BUN,TNF?α,IL?6 and IL?1β. Rat kidneys were rapidly removed for PAS stain. Western blot was employed to determine the expression of NF?κB. Results Pathologi?cal changes of kidney were induced by sepsis and the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly increased by 178%,66%, 55%,114%and 110%(P<0.01). respectively;simultaneously the phosphorylation and nuclear expression of NF?κB p65 in kidney tissues were significantly increased by 144%and 102%(P<0.01). Sepsis?induced acute kidney injury also significantly reduced the expression of IκBαby 61%(P<0.01). These changes were significantly suppressed by early ALA treatment. Compared with C group,the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly decreased by 48%,26%,25%,37%and 40%(P<0.05),respectively,and the relative expression of IκBαwas increased by 103%(P<0.05). Conclusion The present study demonstrated that ALA can suppress the activation of NF?κB,thus ameliorat?ing sepsis?related acute kidney injury.

BACKGROUND:Peripheral facial nerve injury first involves the retrograde reactions of central nervous system axons, and nerve regeneration wil depend on the survival and functional status of neuronal cel bodies. OBJECTIVE:To explore the expression of neuronal cadherin and placental cadherin in facial nuclei after facial nerve injury. METHODS:New Zealand white rabbits were randomly divided into model group (n=48) and control group (n=8). In the model group, every eight rabbits were used to carry out the test respectively at 1, 4, 7, 14, 21 days after the model of facial nerve injury (right side) was established. SP and real-time quantitative PCR methods were taken to test the expression of neuronal cadherin and placental cadherin in the facial nerve nucleus at mRNA and RESULTS AND CONCLUSION:The control group had neuronal cadherin-and placental cadherin-positive neurons. In the model group, neuronal cadherin and placental cadherin positively expressed in the facial motorneurons (right side), and their expressions were peaked at 14 days. Compared with the control group, the mRNA expression of neuronal cadherin in the facial motorneurons was increased significantly at 4-28 days after injury;the mRNA expression of placental cadherin in the facial motorneurons was decreased significantly at 1 day after injury, and then increased significantly at 7-28 days. It is suggested that the expression of neuronal cadherin and placental cadherin is positive in the early stage of facial nerve injury, and the expression of placental cadherin is always present, while the expression of neuronal cadherin relatively lasts for a short time. After facial nerve injury, the expression of neuronal cadherin and placental cadherin in the facial nerve nucleus is both increased, which indicates that the facial nerve regeneration may be related to the high expression of adhesion molecules.
