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.

OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

Objective To investigate the classification of cerebral arteriovenous malformation (AVM) associated with hemodynamics correlative aneurysms and its efficiency treated by endovascular treatment.Methods The clinical data of 17 patients of AVM associated with hemodynamics correlative aneurysms undergoing endovascular treatment were analyzed retrospectively.Results Eleven cases of aneurysms with great divergence between the aneurysm and arteriovenous malformation were embolized,6 cases of aneurysms without a great divergence between the aneurysm and arteriovenous malformation,1 case of aneurysm was treated with stent,other 5 cases of aneurysms were not treated.Eleven cases of arteriovenous malformations were embolized completely,4 cases were embolized 71％-90％ and 2 cases were embolized 50％-70％.Six cases with residual were given radiotherapy.Follow-up 3 months to 3 years,there were no cases of cerebral hemorrhage or death.Unhandled 5 cases of aneurysm and 1 case of stent implantation with the follow-up by using digital subtraction angiography,laneurysm with a stent was closed.Three aneurysms were disappeared and 2 aneurysms were reduced significantly among the 5 cases of aneurysms without treatment.One case of aneurysm occlusion in patients with stent implantation.Conclusions Classification based on a great divergence artery or not between the aneurysm and arteriovenous malformation is more instructive for clinical treatmen of cerebral arteriovenous malformation associated with hemodynamics correlative aneurysm.If it has not a great divergence artery between aneurysm and arteriovenous malformation,arteriovenous malformation after a thorough treatment,aneurysms need not be treated.The endovascular treatment for cerebral arteriovenous malformation associated with hemodynamics correlative aneurysms has a good efficiency and can be treated as a priority.

ObjectiveTo study the effects of perindopril on myocardial energy metabolism and ultrastructural changes in rats with chronic heart failure (CHF) induce by isoproterenol. MethodsTotally 55 male SD rats were randomly (random number) divided into two groups, namely control group (Group C) and CHF model group. The CHF rat models were made by subcutaneous injection of isopreteronol (ISO) in doses of 20 mg · kg-1 · d-1, 10mg · kg-1 · d-1 and 5 mg/kg/d for successive 3 days and then 3 mg· kg-1· d-1 for9 days. Four weeks later, the rats in CHF model group were randomly further divided into two subgroups, namely untreated subgroup (group M ) and perindopril treated subgroup (group P). After treatment for five weeks in average, echocardiography and myocardial pathology examination carried out to assess the cardiac function and structure changes of these rats. The levels of ATP, ADP, AMP, lactic acid (LA) and sarcoplasmic reticulum Ca2+ -ATPase (SERCA) activity in myocardium were determined by enzymatic reaction. ResultsCompared with rats in group M, the ejection fraction of left ventricle (EF) and fractional shortening of short axis of left ventricle (FS) of the rats in group P increased by 3.25％ and 7. 33％, respectively. Compared with rats in group C, the myocardial ATP, AMP, TAN (total adenosine) and LA significantly decreased in rats of group M. There were no significant differences in the levels of ADP, AMP, ATP/ADP and TAN between group C and group P (P ＞0. 05). Compared with rats in group M, the myocardial SERCA activity increased by 16. 41％ in rats of group P. The myocardial injury found under microscope and electronic microscope was ameliorated by treatment with peidolapril in rats of group P in comparison with rats of group M. ConclusionsPerindopril can improve myocardial energy metabolism,and lessen the pathological changes of ultrastructure, enhancing the cardiac function of rats with CHF induced by ISO.

Objective To explore the effects of granulocyte colony stimulating factor (G-CSF)on chronic cerebral ischemia in rats,and its possible mechanism.Methods Chronic cerebral ischemia (2-VO) model was prepared and bilateral external jugular veins were isolated.A total of 30 rats were divided into 2 groups at random sham group (received no intervention,n=15) and operative group (received G-CSF or PBS through external jugular vein injection,n=15).At 6 weeks after operation,the rats in operative group were divided into G--CSF group (received G-CSF 10 mg/L,1 ml · kg-1 · d-1,1 times every 24 h for,3 times) and PBS control group (received PBS 10 mg/L,1 ml ·kg 1 · d-11,1 times every 24 h for 3 times).At 8 weeks after the operation,morris water maze was carried out to evaluate the learning and memory ability of the rats.The cell proliferation,threedimensional vascular distribution,ischemic neuronal apoptosis,cell morphological changes in ischemic area and the plasma VEGF levels were detected to explore the possible mechanisms.Results In morris water maze,escape latency at the 2rd to 5th day were significantly lower in G-CSF group than the PBS group (all P＜0.05).The swimming time spent in the first quadrant in G-CSF group was significantly longer than the PBS group (P＜0.05).There was a significant difference in the number of BrdU positive cells in the ischemical area between the G-CSF group and the control group [(27.7±4.76) vs.(10.4 ± 3.7),P =0.030).Three-dimensional quantitative measurements of vascular structure showed that the capillary diameters was smaller in the G-CSF group than in the PBS group [(2.90±0.20) μm vs.(3.45±0.26) μm,P=0.020] and the number of branch points in the boundary regions of ischemia had a significant difference in the G-CSF group compared with the control group [(207.82±10.73) /0.002 mm3 vs.(162.10±9.31) /0.002mm3,P=0.005].Threedimensional cerebral vessel surface area in the ipsilateral hemisphere was increased in the G-CSF group compared with the PBS group [(86498±2896) μm2/0.002 mm3vs.(73976±3826) μm2/0.002 mm3,P=0.003].The number of apoptotic cells in G-CSF group was decreased compared with the PBS group [(32.10±6.70) vs.(56.30±11.20),F=11.89,P=0.043].The electron microscope morphological observations showed inflammatory edema in intercellular gap was significantly reduced in the G-CSF group compared with the PBS group.The level of plasma VEGF was significantly increased in the G-CSF group compared with the PBS group [(58.81±6.61) ng/L vs.(20.81±4.35)ng/L,P=0.025].Conclusions G--CSF can improve the learning and memory ability in the chronic cerebral ischemic rats,and its possible mechanism might involve the nerve protection and the vascular regeneration associated with the VEGF.There is a great prospect for G-CSF in the therapy of chronic cerebral ischemic disease.
